Population growth in developing countries leads to this fact that funding sources and budget are divided among more people. The people's demands increase and, subsequently, the price of livelihoods, health, security, education and transport increases as well. Globally speaking, education is subject to this phenomenon. The university, as an institution of higher education, is an ever-changing reality. Despite the significant increase in the number of students applying in this sector, budget allocation to universities lags behind. On the other hand, the nature of this population is changing as well because more middle-aged student groups as well as ordinary students enter into this field. Regarding their diverse family status, living conditions, social and professional needs, time to respond to demands and geographical distance, these students have different needs that affect the structure and implementation of education. As such, higher education sector and those universities that are not actively and professionally involved in this inevitable change as well as those universities that do not have a scientific future studies and planning to face this reality will lose market share. There are evidence that indicate that universities and higher education institutions and private sector will share the opportunity of commercialization of higher education and take advantage of this new opportunity. The necessity and demand for continuous and everlasting learning provides a great profitable and economic opportunity and capacity for universities. Commercialization of higher education in Iran is faced with important and challenging uncertainties. Future studies can examine the commercialization of higher education via investigating the past as well as main changes, trends, indicators and emerging phenomena in this domain. Furthermore, alternative scenarios for the future of commercialization of higher education in Iran in an active confrontation with main environmental uncertainties will be identified thereof.

Although many countries attempt to build up this kind of university; In fact, many scientists have had different interpretations from it. Altbach (2003) argues that World-Class university refers to those institutions which meets excellency standards in global ranking. Becoming a member of the exclusive group of World-Class universities is not achieved by self-declaration; rather elite status is conferred by the outside world on the basis of international recognition. Others argue that what makes a university World-Class one is related to prestige and there would be no consistency between the performance of this kind of university and its name. Some others suggest that having at least one World-Class university is helpful for growth and development of countries; While some opponents question joining to the standards of World- Class universities. This article is a descriptive research which aims to study the characteristics of World-class universities; Concentrating on talents, abundant resources and good governance, Using library research, reading academic articles, white papers, reports of international organizations such as World Bank, OCED, UNESCO, and Websites of World-Class universities. Meanwhile considering World-Class university's characteristics, the researcher consider the different approaches of becoming a member of this kind of university as well as its advantages and drawbacks, by upgrading existing institutions, merging existing institutions, and creating new institutions and through creating research universities as well.

The present study, have beendone in order to evaluate the effect of generics-Prone Purchaser Demographics and PcychographicCharacteristics on Generics Purchase’s Decision-Making. The present investigation of a relativelybroad spectrum of variables in connection with generics should serve to enlarge our understanding ofthis market. This study considers five types of segmentation variables: demographics, requirements forprice and quality, Requirements for brand, information seeking behavior, relevant behavioralcharacteristics. In addition to identify generic products Purchaser generally, generic purchase, haveconsidered at three level (none, low, high), toward to demographics and psychographic characteristics.Requirement information have been gathered by Descriptive-Correlational research and cluster, simpleRandom sampling of 265 people at Shahrvand chain store and Tehran grand market by using of validand reliable questionnaire. For testing hypothesis have been used of One-Sample T Test, Independent-Sample T Test, One-Way ANOVA and Univariate ANOVA, and have been analyzed through SPSS16software. The findings shows that price proneness, quality proneness, less brand loyalty, private( Vs.national) brand proneness, personal source usage, general change proneness, venturesomness,innovativeness and less perceived risk were determined to be positive influences on purchase ofgenerics .On the other hand, label readership, electronic and print media usage and approval ofadvertising were determined to be reverse influences on “high” generic purchaser group and finallypurchaser generics were characterized to be younger and married.

Conclusion: In the current situation, there are many challenges in the field of research quality in the country. In order to achieve research quality, components and indicators of research quality improvement should be considered. Universities and higher education institutions must organize research quality programs on a larger scale to meet the community's demand for progress and development. Considering that in recent years, in our society, higher education has paid attention to quantity and the downward trend of the qualitative indicators of its research is clear. Considering the internal and external issues facing the higher education system, the issue of quality reduction and the need to pay attention to it should be addressed. Be considered serious concerns of society. In order to improve the quality system of higher education research, there is a need to rethink and reconstruct the functions and quality programs of higher education and use a systemic approach in academic analysis, with regard to the commitment and responsibility of all officials.

The criticism procedures should satisfy the needs of all the stakeholders who participate in architectural design process. Criticism has a lot to do with a wide range of tangible and intangible issues such as environmental, social, technical, economic, aesthetic and fictional issues. Therefore performance-based criticism is an approach to evaluate architect's success in meeting aims and objectives of all the stakeholders who might be interested in the project. It is essential to explain that the level of architectural performance is effected by “context”. Moreover high-performance architecture might be crystalized through the relationship of form and content. This paper is to make a framework for discourse of high-performance architecture in order to shape a Method to understand contemporary architecture. As well as make a substantive model to criticize strength and weakness on contemporary architecture, especially contemporary architecture of developing countries such as Iran. Contrary to much of conventional approaches, architecture criticism not only study building beyond the way it performed but also prefer to analyze hidden dimensions of architectural design process. Theoretical framework of the paper is based on understanding architecture as a comprehensive discourse. Assumption of the research indicates that architecture is a matter of discourse and comprehensive meaning of high-performance architecture might be understood by adopting the relationship between architecture and architect as a critical discourse. It is essential to describe performance-based design as way to meet demands and expectation of all the stakeholders in architectural design process, especially in programing and planning phase. The research methodology of the paper is based on discourse analysis theory in order to explain the relationship between architecture and context as matter of understanding the level of performance. Moreover the research methodology aims at revealing socio-cultural, ultramundane, intangible and psychological characteristics of “architecture” rather than tangible and physical issues. The results of the paper show that a comprehensive approach toward architecture criticism includes five categories of all-inclusive and interdisciplinary strategies such as: 1- Relation to Context: high-performance architecture has to crystalize a meaningful learning from nature. The interrelationship of performative characteristics of architecture, recombinant materials and socio-cultural aspects of design. 2- Process-Based Approach: Understanding the level of performance is to concentrate on process in order to meet stakeholders’ demands and objectives. 3- General Welcoming: Performance-based design has a lot to do with collective mind. 4- Recriticizing Critics of Critics: Architecture might be read in contemporary discourses. Architects sometimes have their own approach toward architecture criticism which might be called designerly way of knowing and doing which works as a new style of architectural criticism. 5- Redevelopment of Future Discourse: New architectural technologies such as digitalism, mathematical architecture etc. are about to shape a new paradigm for future architecture. Based on theoretical developments future legacy in architecture is in need of a kind of futuristic discourse. It is essential to redevelop future discourse in programming architecture.

Memorable elements are the ones that can cause memories and sense of belonging by locating in mind. Being unique and criterion cause quick images to remain in minds and these elements cause the space to become an indicator of spatial identity. To become a memorable space and to remain in minds some schemes should be created in minds and this is the fundamental condition. Furthermore, the space should have a definite and unique identity. It is essential to recognize basic elements of creating mental spatial and social schemes and to investigate their effectiveness in the components of memorability. The purpose of this study is about urban highways and similar spaces. On the basis of posed theories, the hypothesis is as follows: there is a relation between memorability in highway observers and mental spatial and social schemas schemes so that creating mental schemas can help in creating observers’ memorability. On the basis of this proposition, creating mental schemes is the essential condition for memorability in green urban highways. The proof of this claim is achieved by referring to empirical evidences. The research methodology includes analytical-descriptive techniques. The statistical populations of 51 bystanders of the Modares highway margins were surveyed. Statistical analysis included descriptive and inferential techniques. The findings show that, in designing the urban highways paying attention to spatial-social schemas is one of the main components for generating memorably of highway margin by criteria. According to the results of the analysis of experimental findings, it seems that considering spatial-social schemes are one of the main components of creating a memorable environment for bystanders who visit routes such as highways. Variables such as age, gender and level of education do not affect the influence of the kind of mental spatial and social schemas so much and this issue can be used in creating most common indicators between different groups of citizens with different ages and level of education for designing a green and memorable highway. The most important criteria in the design of green urban highways space includes design style of highway space, detail Fitness in highway such as trees, elements and street furniture with generalities and its overall configuration, heterogeneity and diversity in the details. Because people have less time to remember and visualize the symbolic elements in the highways the use of such elements has less effect on their mental schemes and also the memorability of environment. Memorable elements should have a unique identity cause impression on the minds. According to the results of this study, there is a linear relationship and a high correlation between memorability and creating mental spatial and social schemes. It means to make a space memorable some schemes should be created in minds to make the space effective and persistent. Several sequences and focus points in the special parts can lead us to have a convergence mental schema Manuscript profile -

On the other hand, in this type of building, because of high user density in a limited area and the considerable use of energy resources during construction and exploitation, sustainable attitude have to be pursued not only in design process but also during exploitation. Since achieving the goals of sustainable architecture is impossible without attention to user’s behavior, the psychological terms and behavioral sciences play the key role. In this regard, few of the researches that have already been done are about the psychological and behavioral aspects of sustainability attitude. In This paper, the role of environmental psychology in sustainable high rise building design is recognized and also in order to promotion of this type of behavior through Maslow pyramid model of needs, the ways and strategies are explored. In the next step, with considering of the role of “attitude” in promoting individual and social behaviors, the strategies of “education” and “resources management” have been presented. Finally, environmental psychology as a basis for motivating sustainable behavior by users is introduced. Manuscript profile -

In the absence of noise traders trading volume would severely decrease. However, on the other hand, market microstructure noise deviates prices from their fundamental values. In this paper, we separate the microstructure noise from the price process and then we ask whether high frequency estimates of microstructure noise contain a risk factor and whether that risk factor is priced in the market, meaning that stocks that covary with our high-frequency measure of noise tend to get compensated in the form of higher returns. We examine this question through a portfolio switching approach by looking at the returns of portfolios sorted on our high frequency measurement of the magnitude of the market microstructure noise. The results show that the portfolio corresponding to the highest quartile noise outperforms the portfolio with the lowest quartile noise. Manuscript profile -

The sample of this study composed of stocks of companies listed in Tehran Stock Exchange from Farvardin 1381 until the end of Esfand 1392. To test the profitability of these two strategies, we use portfolio level analyses and Fama – Macbeth Cross sectional regressions (1973) in throughput. The results of this study confirmed the profitability strategy "The timing of 52-week high price" while winner portfolio based on"52 week high price " strategy could not yield higher returns in compare with looser one,therefore the profitability of "52 week high price "strategy is not approved. Our findings indicate that "the timing of 52-week high price" is able to predict changes in cross-sectional returns, but the point about the "52-week high price" does not apply. The results show that the interaction of these two strategies improve predictive power for stock returns. Manuscript profile -

For this purpose, reed plant flour, high density polyethylene, and oxidizedpoly-propylene compatibilizer in the specified value were mixed into the internal mixer for 6 min and after that, theresulting amorphous materials turned to the granules using a laboratory mill. Finally, the granules turned to reed-plasticplates using a hot press. Mechanical tests such as bending and tensile resistances and their modulus and physicalproperties such as water absorption and thickness swelling in 2 and 24 h were measured. A fourier transform infraredspectroscopy machine was used to check the modification of oxidized poly-propylene and the morphology of thecomposites was studied by electron microscopy images. The results demonstrated that with increasing thecompatibilizer, the mechanical properties were linearly increased, while the water absorption and thickness swellingwere decreased. Electron microscopy images showed that improved adhesion at the interface between the reed plantflour and polymer fibers.

And now as time passes, its dimensions are more evident and have attracted the attention of the relevant authorities and urban designers. Installation of noise barriers near highways is the most common way to reduce noise pollution. Noise barriers do not often have the necessary efficiency for the societies in which they are expected to work. However, in some cases, with a little accuracy in design, these barriers would have a considerably high efficiency.This paper evaluates different active and passive protection methods to control noise pollution in the highways and studies effective factors used in highways as a passive control method of sound barriers.

In this article, the most important question is related to the concept of Feeling from Schleiermacher’s viewpoint with emphasis on his works up to 1792 C.E. Schleiermacher lived in a time when philosophers were faced with a kind of metaphysics and theology, that was so different from those of antiquity and the middle ages. Although the main themes of philosophy, such as God, the soul and its immortality, had not lost their focus; philosophers, looked at them from a different perspective, and this led to a revelation in the systems of Scholastic Theology. On the one hand, Schleiermacher is known as a famous priest, and on the other hand, he is known as a philosopher who is influenced by Kantian philosophy. He seeks to redefine religion according to the concept of “Feeling” in his philosophical theology to rescue it from its decline into Kantian morality. In his early treatises, under the influence of Aristotle and Greek philosophers, and the Kant’s transcendental philosophy, he tries to save Christian theology from the domination of Kant’s ideas and Enlightenment rationalism.

Due to their relatively short lifespan, strong effect, and extensive variety of biological activities, carbamates are one of those that are frequently utilized as insecticides. The need to monitor the presence of pesticides in food products is a major concern because of their major risk on consumers' health.Materials and Methods: In the current research, Aldicarb, Carbaryl, and Primicarb insecticides were extracted from apple samples using a combination of QuEChERS technique with dispersive liquid-liquid microextraction, and their determination was carried out using HPLC-DAD. For this purpose, the effect of the effective factors in the two stages of the proposed extraction process was investigated and optimized. Also, merit figures including linear range, limits of detection and quantification, repeatability, enrichment factor, and extraction recovery were calculated in order to validate the developed method.Results: Concerned with the broad linear range (10.7-2000 ng/g) and the repeatability based on RSD% of 2.6 to 4.8, the proposed method proved highly capable of extracting the desired pesticide residues from apple samples. Under optimal conditions, the suggested approach had an extraction efficiency of 67–75%, an enrichment factor of greater than 335, and limits of detection and quantification of less than 4.2 and 14 ng/ml, respectively, which were less than the MRLs set for these pesticides in fruits and vegetables. The mentioned method was successfully performed on real apple samples and the results revealed that the samples did not contain any of the expected carbamates.Conclusion: In general, the developed method has the necessary ability to detect carbamate insecticides in apple samples. This method offers several advantages of being simple and reliable, employing green solvents, and short analysis time. Manuscript profile -

Monitoring the amount of antibiotic residue in milk is crucial in order to alert the nation's health authorities and in this regard, several researches have been conducted for determination of different antibiotic residues in milk using various traditional and chromatographic methods. In this study, an efficient method for determining the residual levels of some sulfonamides in pasteurized milk was developed and presented. Materials and Methods: After dispersive solid-phase extraction combined with air-assisted liquid-liquid microextraction of analytes, the residues of sulfadiazine, sulfamethoxazole, and sulfamethazine in the pasteurized milk were determined using HPLC with a diode array detector. Following the evaluation of the effective factors in the extraction and optimizing them, the validation of method was carried out by calculating analytical parameters such as linear range, LOD, LOQ, repeatability, and extraction recovery. Results: In the developed two-step extraction method, satisfactory figures of merit were obtained, therefore the method's linearity was shown with a coefficient of determination higher than 0.995. The limits of detection and measurement were less than 1.2 and 3.2 ng ml-1, respectively, which is less than the MRLs established for these antibiotics in milk. The analysis of real samples showed the presence of sulfamethoxazole in three milk samples in concentrations of 13±0.1, 9±0.2 and 9.6±0.5 ng ml-1 and no other antibiotics were discovered in the examined samples. Conclusion: Overall, the established approach is a sensitive, accurate and reliable method and has high efficiency in determining selected antibiotics in milk samples. Manuscript profile -

The nonsaponifiable components of vegetable oils are good sources of specific compounds such as sterols, tocopherols, squalene, fatty acids, and other substances. The aim of this investigation is to determine the components in particular α-Tocopherol and β-Sitosterol through deodorization process and have been accumulated in the distillate tank.Materials and Methods: Olive oil and distillates were provided by Roghan-e-Ziton Nabe Tavakoly manufacturing company. Sterols ad tocopherols were evaluated before and after the deodorization process and in the distilled tank. Qualitative and quantitative determination of sterols and tocopherols were conducted using gas chromatography and high-performance liquid chromatography after the extraction of nonsaponifiable matters.Results: The results showed that the deodorization process decreased the nonsaponifiable matters of olive oil such as sterols, tocopherols, hydrocarbons and some other components namely free fatty acids. Due to the lower temperature of the deodorization process for olive oil, in comparison to soyabean or sunflower oils, the accumulation of these components in the distilled tank were lower. There was no significant difference between sterol composition in distilled tank and oil samples.Conclusion: Collected compounds in the distilled tank are valuable sources of vegetable sterols and α-tocopherol which might be employed in food and pharmaceutical formulation and industries.

The advantages of this device in different industries are its relative simplicity of construction, low operating cost and reliable under extreme working conditions. Today, cyclone separators have become one of the most important particle removal devices in the fields of science and engineering. Due to the wide application of cyclones in industrial processes, especially thermal power plants, the study of the performance of cyclones at high temperatures is of particular importance. In the present study, two-phase flow simulation within a cyclone will be performed in three different dimensions using the Eulerian-Lagrangian approach in order to study the cyclone performance in a wide range of temperatures, and finally the problem of its lower performance will be substantially resolved by using appropriate geometry of vortex finder. Material and Methodology: In this study, the effect of inlet temperature on the flow field and the separation performance of a cyclone has been comprehensively investigated using CFD simulation. The Euler-Lagrangian approach has been used to simulate airflow and particle dynamics in cyclones. In addition, four proposed vortex finder geometries were considered and compared with the basic geometry in order to evaluate how the vortex finder affects the cyclone performance under a wide temperature range (293 K-700 K). The validity of the numerical model is confirmed by comparing the predicted pressure drop with the experimental data and numerical results in which there is a good agreement was achieved. Findings: The results demonstrated that increasing of inlet temperature significantly reduced the tangential velocity and led to a sharp decrease in the cyclone separation efficiency. All of the proposed vortex finders affected the flow pattern within the cyclone at all inlet temperatures. The simulation results showed that the highest tangential velocity observed in the cyclone was with CVF 1, which also had a positive effect on the relevant separation efficiency. Also, it is proved that the proposed cyclone with CVF 1 was able to collect finer particles (2 μm) at high inlet temperature (T = 700 K). Discussion and Conclusion: In the present study, while examining the performance of cyclone using the Eulerian-Lagrangian approach in three dimensions over a wide temperature range, a suitable solution to improve efficiency and solve the problem of efficiency drop at high temperatures was presented. By properly changing the dimensions and geometry of the vortex finder, the flow in the pre-separation zone can be well controlled to improve particle separation efficiency. Manuscript profile -

Therefore, a proper understanding of leakage behavior and its relationship with pressure variations can play a significant role in water loss control. The use of high-density polyethylene (HDPE) pipes has increased in recent years in water distribution networks so that in some rural area and small cities, these pipes have been utilized only. The aim of this study is to investigate the leakage behavior of orifices in HDPE pipes. Method: In the present study, the leakage behavior of polyethylene pipes has been investigated numerically and experimentally. In this study, the effect of temperature as one of the main factors on leakage behavior has been considered. Findings: The results showed that the Torricelli's classic relationship for the orifices can be used and the amount of leakage exponent for the orifices is approximately 0.5. This study shows that the discharge coefficient of the outflow from the orifices is dependent on some parameters such as Reynolds number, the thickness of pipe wall, orifice diameter, surrounding environment and orifice deformation. Discussion and Conclusion: The assumption of no deformation for the orifices in HDPE pipes with increasing pressure, particularly at high temperatures, is not necessary true. The symmetry state of the orifices in low-elastic pipes is removed with the pressure increase, due to the distribution of stress at the opening and also the effect of the Poisson coefficient, thereby reducing the discharge coefficient.

Moreover, the origin of pollutants was detected by the HYSPLIT model and satellite images. HYSPLIT model determined the origin of widespread pollution. It could detect them with the backward method in three levels, which included 10, 1500, and 5000 meters. Some maps were produced for satellite images and HYSPLIT models drawn in GIS. Findings: In the extratropical pattern, the dust from Syria, northeast to south-east Saudi Arabia, central, northern and southern Iraq and parts of Turkey have affected Tehran. According to HYSPLIT model outputs, at a lower level of the atmosphere and the middle level of the atmosphere, not only the local situation but also the regional situation had a considerable role. At the upper level of the atmosphere, environmental pollution could become into Tehran by streams. In the compound pattern, Saudi Arabia, Iraq, Syria, Jordan, and some parts of Turkey had an important function. In the HYSPLIT model, the North-East and North-West of Iran have attempted to influence Tehran in the lower level of the atmosphere. In the middle level of the atmosphere, the local situation is more remarkable. At the upper level of the atmosphere, the origin of dust was western to eastern parts of Iraq and the northeast part of Iraq. Further, the dust on the north-eastern of Syria, Jordan, and parts of Turkey is more notable. Conclusion: These maps were categorized into two main synoptic patterns, including extratropical and intricate patterns. Manuscript profile -

The “hidden water” and the “hidden energy” of building material are from among the most important issues in designerly approach to energy efficiency under the high-performance architecture theory. The aim of the research is to outline the concept of design for disassembly in order to minimize construction and demolition waste (C&DW) and facilitate appropriate disposal. Materials and Methods: Descriptive-analytical method has been adopted in which description of the theoretical concepts has merged with an analytical approach to the expert opinions. Results: Studies have shown that the successful cases in the framework of design for disassembly were deliberately designed with dismantling prediction from the early stage of the design process. Integrated approach toward the life cycle is the key factor in eco-friendly design and construction which is based on recycling, creative reuse, repurposing and upcycling strategies as a part of “green aesthetics”. Discussion and Conclusions:The concept of design for disassembly rots from flexibility in architectural design process and is an influential procedure for C&DW. The life cycle assessment (LCA) is a comprehensive methodology to address gains of the concept of design for disassembly. Moreover it has showed a meaningful relationship between design for disassembly and the environmental impacts which might be addressed as designerly approach to energy efficiency.

Consideri MoreBackground and Objective: Due to the high spatial resolution of Geoeye data, due to the wider distribution of pixels, the output maps in Neural network algorithm and Forest cover index (FCD) classification methods are more sensitive and with more pixel detail. Considering the large amount of information in new sensors, the aim of this study is to develop and improve the performance of more complex classification algorithms for the interpretation of modern satellite data. Material and Methodology: FCD model base classification is based on four main indicators: sensitive to shadow, uncovered soil, vegetation conditions and density, and without the need for a training sample. The Neural network algorithm operates with high sensitivity to the original image bands and the bands created and added to the image, as well as training samples. Training samples were determined in the summer of 2016-2017 from series 5 and 6 of 30 Ramsar watersheds. Finding: Using this method, an accuracy of 24.5% was obtained for the FCD method and 26.2% for the Neural network method. Due to the high resolution of the data used, the output map developed in this method is associated with a high density of polygons. Discussion & Conclusion: Due to the range of pixels in the output maps of the two methods, an extended method has been proposed to produce a more accurate map, due to the high spatial resolution of the Geoeye sensor. In this method, by reclassifying within the maximum frequency range of pixels, the demarcation of polygons in much smaller and more accurate dimensions is considerable. Manuscript profile -

Limi MoreEnvironment and natural resources as a pavement of sustainable development, is considered as a supportive factor for natural life and cultural heritage of the human society. The increasing growth of population has caused the necessity for job substitution services. Limited resources and lack of capable pattern for development have caused a lot of pressure on environment and restoring natural resources. Destruction of environment and natural resources has attracted the attention of planners and policy makers as a global problem. The trend of environmental destruction and natural resources of our own country is not an exception from this rule. Education is recognized as a profitable investment in development process, especially sustainable development and establishing changes and reforms in order to prevent the destruction of the environment and restoring natural resources. One of the important accelerating factors is public training especially educating students. This process only would take place if the training and education is compatible with the right conditions. For this purpose, this research has been delivered on high school level students of the city of Tehran to find out their knowledge and awareness about the environment and protecting it. Population of this study is about 470,000 students. This is an applied research with the Descriptive-Correlation method. A questionnaire was used to collect information and data. Data is analyzed by using SSPS software. The results obtained from Spearman Correlation coefficient between independent parameters of age, parents education, listening to the radio programs, watching the television programs, having access to forest and green spaces, studying books about environment. With the related parameter of students’ awareness about environment indicated that, there is a significant relationship between mentioned parameters. The obtained results of individual effects of independent parameters on related parameter through the tests of Keruscal-Walis and Man White Nee, indicated that the independent parameters method of acquiring information, using of magazines, participation in related activities, participation in educational classes and membership in environmental organizations, have direct effects on students’ awareness about the environment. However, the parameters of genders, educational achievement, educational field, deferent student organizations and being a member or not having a membership in students’ organizations have no effects students awareness about the environment. The obtained results of total effect of independent parameters on dependent parameter of students interest on environment through multiple regression indicated that the parameters of studying environmental books and journals have had positive effects on students awareness about environment.

Two measures of negative skewness coefficient and low to high volatility were used to measure the stock price crash risk. In this regard, the financial data of 131 companies during the period 2014-2019 have been extracted and analyzed by systematic elimination method as a statistical sample of research. Statistical analysis was performed using Eviews9 software at 95% confidence level and panel data and linear regression model were used to test the hypotheses. F-Limer (Chow) and Hausman statistics were used to determine how the regressions fit. The normality of the error distributions was evaluated by the Jarkue-Bera test, the residual independence was estimated by the Durbin-Watson statistic, and the test of variance by the Bartlett test. The results showed that there is no significant relationship between dividend reduction and the stock price crash risk according to both mentioned criteria in companies. Based on the results of the third hypothesis test (taking into account the first index of stock price risk), the ratio of independent directors intensified the direct relationship between the decrease in dividend yield and the Stock price crash risk. Finally, the level of tax avoidance is directly related to stock price crash risk in companies. This result shows that tax avoidance has led to the accumulation of bad news in the company, which with the disclosure of this news leads to a decrease in stock prices. Manuscript profile -

However, the noise content of this data may negatively affect the results of studies on market microstructure. Using maximum likelihood methodology, we disentangle from high frequency observations on the transaction prices of a sample of Tehran Stock Exchange stocks a fundamental component and a microstructure noise component. We then relate these statistical measurements of market microstructure noise to different financial measures of their market depth. We find that stocks with higher market depth have higher noise measured from their high frequency returns. This is in accordance with Fischer Black’s hypothesis that the existence of noise traders and the noise, which can be caused by the activities of this group of traders, to be the vital condition of a liquid market. We also find that pre-trade depth measures are the most powerful depth measure in explaining the noise in the market. Manuscript profile -

Proposing a high-frequency trading system has advantages (taking advantage of intraday stock market volatility) and disadvantages (high amounts of transaction cost due to the high transaction volume) thus we can augment advantages and cotrol the disadvantages by designing the system elaborately. In this research, the “Local Traders” approach for predicting the future trend of stock has been utilized. According to the “Local Traders” approach, there is a local trader (an agent) for each stock which is expert on it. It predicts the future trend of its own stock based on stock’s intraday data and their technical indicators by determining how much it is good to buy, sell or hold. Results show that, the proposed model outperforms the Buy and Hold strategy in all kinds of markets (Normal, Ascending, Descending) even if there is no discount on Transaction Costs.

In many of these studies, universe of discourse and relevant intervals have been determined based on levels of price or data; in this study a new type of universe of discourse is established based on rate of return concept in financial markets. Another point that has a significant effect on the performance of fuzzy time series models is the length of intervals, therefore doing research in this area became an interesting topic for time series researchers, there are some studies on this issue but their results are not good enough. So we propose a novel simulated annealing heuristic algorithm that is used to promote the accuracy of forecasting. The experimental results show that proposed model (RBFTS) is more accurate than existing models on forecasting Alabama university enrollments data. At the final step, Tehran’s bourse price index (TEPIX) is used as a case study for forecasting. The obtained results indicate a good forecasting performance on this test problem. Manuscript profile -

(Financial companies, companies with fiscal year different from end of 29th of isfand, companies which their stocks were not traded in past 3 month and those which listed after 1389 are excluded). Then portfolios based on the third and fourth moments are formed by the sampled companies. We used three pricing models including CAPM, Fama- French 3 factor model and Carhart Model for each portfolio. Results show that estimating these models accounting third and fourth moment lead to increase of significance of these models. But the insignificance of the interception of difference between two portfolios showed that third and fourth moment premium are not priced which can be due to assuming homogeneous investment horizon for investors. For this, using wavelet analysis, we analyzed three portfolios with in two horizon levels including level 1 (2 to 4 month) and level 2 (4 to 8 month). Results interestingly showed the improvement in significance and also in R^2. Using GPH estimator, we showed that there is long term memory in studied time series. In order to making these series stationary, we used recent method by calculating fractional data and again we estimated the models. Results showed that models estimation significantly improved for all three portfolios. But except CAPM for the two first portfolios, in other models the risk premium is not priced. Comparing fractional models with those obtained by wavelet models strongly indicates the superiority of the latter. Comparing all models, we concluded that best model for pricing, based on the third moment, is fama- French 3 factor model in level 2 daubeechies4 and by regarding the fourth moment, CAPM is optimal one for the level 2 symlts8.

This phenomenon is studied in different countries and in various financial variables and several hypotheses have been put forth to explain that. In this study, existence of this price clustering and factors affecting on it is tested in Iran capital market. To this, high frequency data is used and by means of statistical tests, the existence of price clustering is observed in Iran capital market. Furthermore, among all variables, only size, price and a dummy variable to distinguish between Tehran stock exchange and Iran Farabourse exchange, were effective on the intensity of price clustering and despite the expectations, size variable has a positive coefficient. Results are corresponded to odd-pricing, price resolution (just for price variable and not for size) and negotiation hypothesis. Manuscript profile -

Habitat variables such as percentage of plant cover and Height of plant for each plant species separately; slope, soil texture, and distance to the nearest road; as well as farm and water resource around animal nest were measured by the establishment of sampling units near the animal hole and compared with the nonappearance locations. The results showed that regions with rather soft soil texture and higher percentage of (Atraphaxis sp) and sagebrush (Artemisia sp) plant cover with a gentle slope are preferred by this animal. The higher percentage of plant cover of two species of Atraphaxis sp and sagebrush provide the required cover for the nest. With regard to water and wind erosion in the region, the low slope prevents the destruction of the nest by water or soil. Furthermore, distance to the road keeps the eggs protected from human disturbance. Saving the population of Spur-thighed tortoise in this region depends on the protection of the structure of plant communities and soil. Manuscript profile -

Contact with these fields will adversely affect the human health. On the other hand, extent of these sources due to the waves’ invisibility and propagation from different sources has increased the importance of these studies. The aim of this research is to evaluate the magnetic flux density in the vicinity of the high-voltage power lines and determine the critical points in GIS. Materials and Methods: In this field research, measurements were conducted in 13 districts of Isfahan using wave-measuring device (HI-3604) according to IEEE standard in 522 points. The results were analyzed by SPSS and GIS. Findings/Results: Minimum and maximum magnetic flux densities were 0.13 and 4.6 µT measured at 0 and 20 m distances from the high-voltage power line, respectively. This shows that the measured quantitates will be declined by increase of the distance and height and reduction of the current. A significant relationship was observed between the magnetic flux density and distance, height and current (P-value>0.05). Discussion and Conclution: The results also suggested that the magnetic flux density was lower than the ICNIRP in all the investigated points. However, regarding the consequences of these waves even in far smaller levels (compared to the standard) on the human health, the residential regions should be established in proper distance to these lines to minimize the exposure. In GIS, the critical points were observed in Shafagh Blvd. in vicinity of line 230; while the safe pints were located in Vali-e-Asr St. in vicinity of 63-kV line. Manuscript profile -

This has resulted in some patterns that reduce its disturbing effects along with improving the quality of life in these cities. Mankind is aware of the value of the sustained spaces and is trying to answer his needs, holding permanent horizons in view. These efforts resulted in patterns of sustained metropolises, a steady and dense city. But this human achievement is not, like his other achievements, without a consequence. Research shows that increase in the density of the city disturbs the balance in the illumination of the city spaces in addition to damaging the heat transfer between the earth, buildings and the atmosphere. It also affects the internal heat of the city, increases the temperature and influences the velocity of the wind. In another view, higher density means a decreased opportunity for building green spaces resulting in a demolished desirability of the spaces. It also results in crowdedness and brings about air pollution. As flat planes that occupy a large share in such dense cities, roofs are of great importance to us. Good effects of green patterns on improving the climatic conditions like moderating undesirable consequences of dense cities decrease of heat and sun waves, the velocity of the wind and pollution posits a good potential in plans. Bruce’s non-hydrostatic model is used in this research to simulate a site in three conditions of its current state, increase in density and greening the roofs. Then effects of rooftop greening especially on air temperature and wind velocity are studied. Finally a comparison is made between the results of this research and other researches done in this field t achieve a broader insight into how greening the roofs may affect low-scale environmental conditions specially in dense cities by using plants in higher scales.

Highlighting means the poet's capacity to use his (or her) linguistic and musical games and artistic possibilities; in a way that his own expression is defamiliarizing and prominent. Rumi created interesting harmony between structure and content by enjoying highlighting structures of the text such as phonetic, lexical, syntactic and musical structures. The purpose of this article is to propose an image of Rumi's artistic and prominence level. The present research which analytical-descriptive method is used according to the structural approach studies the sonnet in terms of phonetic, lexical, syntactic and semantic aspects. The result of the present study is that Rumi, has separated and distinguished his poetic language from the usual norm in the poems of others benefitting structural and semantic innovations,.

In this regard, in a descriptive-analytical study, we intend to examine the tools of poetry creation, especially its deviation in one of the poems of the prominent Iranian poet, Malek Al-Shoaraye Bahar. For this purpose, after a brief deviation to the pattern of linguistic deviation that was proposed by formalist linguists, especially Jeffrey Leach, the poem "Damavandieh" was analyzed from the point of view of this pattern. The results of this study showed that Bahar in his poem has more or less used all types of deviations, in which the frequency of semantic and temporal deviation is higher than other types, and this can be on the one hand, due to the prevailing political atmosphere during the life of this poet and the silence and indifference of the people towards his destiny and on the other hand, the deep study and attention of this poet to the works of previous poets and adherence to the traditions of the past.

In this approach, methodology is prescriptive and offers some do’s and don’ts about literature. On coming new literary methodologies, researchers discussed different aspects of literature and employed a pragmatist approach. The advantage of such theories is to use and appropriate them with certain texts to crystallize the theories. In this research, eight types of deviation (lexical, syntactic, vocal, writing, semantic, dialectical, stylistic, and temporal) are studied based on Leech’s deviationism (1969) in Ibn Hesam’s poetry. The results show that semantic deviation is more frequent than other forms of deviation. Syntactic, temporal, lexical, vocal, stylistic and dialectical deviations are more frequent, respectively. Writing deviation which is mostly associated with modern poetry had no frequency in his poetry. Manuscript profile -

They introduced literary language as deviating from the standard language and studied the style accordingly. Although the Holy Quran is not a literary text, but in terms of lexical, linguistic and rhetorical, it is considered a wonderful miracle that its study based on new perspectives can be a solution to achieve new findings. The present study seeks to examine the twenty-ninth part of the Holy Quran from the perspective of syntactic deviation using the analytical-inferential method. Findings indicate that syntactic deviation is represented in the form of presentation and delay, with the aim of highlighting a part of speech, omission with the aim of brevity and aesthetics, attention with the aim of aesthetics of speech and conceptualization, and repetition, due to emphasis.

Highlighting could be known equal with norm deviation in literature; because highlighting is based on poet's deviation from rules and standard language; poet attracts the reader's attention to other viewpoint and aspect by norm deviation. In other words, a poet deviates from standard language to attain the literature by enjoying some tricks. Thus highlighting means abnormal and uncommon language to form a literature. The present research studies highlighting and the issues may result it in two odes by Ahamd Mattar. The method is formalistic and all factors cause highlighting have been expressed in this research.

Most reports of this disease in the nonwaterfowl wild birds are the H5N1 subtype. The least susceptibility to HPAI viruses has been observed in the pigeon and starling spicies, and probably these spicieshavethe least role in the epidemiology of these viruses. While other Passeriformes, Falconiformes and parrots are highly susceptible to HPAI. In the most reported outbreaks in the Falconiformes and crows, the main causes of the infection were using the carcasses of the affected birds or contact with them. The main cause of the susceptibility of these birds to the influenza viruses is the presences of the alpha 2 and 3 sialic acid receptors in the respiratory and gastrointestinal tracts of them. The most common signs that observed in these birds are neurologic signs and the highest viral concentration has been observed in the brain.Due to the susceptibility of non-waterfowl wild birds, and the large number of these birds and the close contact between migratory birds with domestic and industrial birds and the possibility of transmission of infection to other birds and humans, these birds should be considered in the designing of influenza surveillance programs and in the outbreaks of HPAI.

The present study is an applied research in terms of purpose and in terms of the nature and method of data collection, the present study is correlational. The statistical population in this study consisted of 5938 high school teachers in Bushehr province, of which 361 were selected as a sample according to Morgan table. It should be noted that out of 361 questionnaires distributed, 250 questionnaires were returned. In fact, 75% of the population has responded. Therefore, the results were completed based on 250 questionnaires. Two questionnaires were used to collect data. Parsons 28-item questionnaire on organizational effectiveness based on the criteria of achieving or achieving the goal, adaptation or innovation, coherence or unity and continuity or maintenance of patterns, as well as a researcher-made 25-item talent development questionnaire in 6 dimensions: genetic, emotional (personal characteristics), cognitive (intelligence). Talent, environmental suns (home, school, community, gender and luck), thorns were used. The reliability coefficient of the Talent Development Questionnaire (0.88) and the School Effectiveness Questionnaire (0.83) were obtained and since Cronbach's alpha of both questionnaires is more than 0.7, Therefore, they have the necessary reliability. SPSS23 software was used to analyze the data. Data were analyzed using descriptive and inferential statistical tests (relative frequency, mean and standard deviation, Kolmogorov-Smirnov, Spearman correlation coefficient). The results of the test to evaluate the status of the components of talent development showed that among the six dimensions studied, only two dimensions, the emotional dimension with an average (3.89) and the cognitive dimension with an average (3.92) have a suitable status. The results show that the dimensions of teacher talent development have a significant relationship with the effectiveness of secondary schools in Bushehr province. The results of this study can take steps towards education to improve teachers' job ability, pay attention to their talents and try to create solutions for the development of talents in order to provide better services to students.

Method: The research method in this research is descriptive and content analysis type. The statistical population included all sociology textbooks of the second year of high school. Considering the nature of the research topic and due to the limited statistical population, sampling was omitted and the entire statistical population was considered as a sample. In this research, the unit of image analysis is question and activity, and Shannon's entropy method was used for data analysis. The validity and reliability of the research tool has been confirmed. Findings: The main findings of the research indicate that out of a total of 893 units for the components of cultural competence, individual competence, academic competence, religious competence and environmental competence, respectively, in sociology books of the second year, the importance coefficient is 0.2398., 0.2549, 0.2547 and 0.2518. The highest coefficient of importance in the content of the sociology textbook of the second year of high school is for the component "academic competence" (0.2549) and the lowest coefficient of importance is related to the component "individual competence" with the coefficient of 0.2398. Conclusion: The general result of the content analysis showed that although the characteristics of cultural competence have been paid attention to in the sociology textbooks of the second year of high school, but the amount of attention paid to the components of cultural competence in different courses is unbalanced. In some courses, very little attention has been paid to some components, and this leads to students not being aware of these components. Balanced attention to the components of cultural competence are different from each other. It is necessary that the current state of teaching the components of cultural competence is not comprehensive enough. Manuscript profile -

As part of the ongoing search for pharmacologically active lead structures, the obtained structural diversity allows for the fast exploration of a large chemical space. Not surprisingly, the development of MCRs, leading to new structural frameworks or serving as key transformations in the total synthesis of natural products, has expanded rapidly over the last few decades. To date a multitude of new three- and four-component reactions have already been described; however, examples of ‘‘higher-order’’ MCRs where five or even more components are combined in a single reaction vessel are remarkably scarce. With the growing interest for biologically active small molecules at the end of the 20th century, the application of MCRs to create libraries of such small, drug-like molecules was investigated with a steadily increasing intensity by industry and academia as a result of its superiority over other approaches (i.e. the use of readily available starting materials, inexpensive and easy to carry out chemistry, broad product spectra, high diversity in few steps, ease of automation, etc). This tutorial review aims to critically describe the developments achieved in recent years, charting the ideas, challenges, and milestone reactions that were essential for the progress of this field.

The meaning of Form in this trend refers to the format of stating or meaning making method. In this style all the preperations that are at the service of developing a new and original form of representing meaning are considered as the inner aspect of the form and the way words are written on the paper، playing with words، repetition and so on are considered as the outer aspect of the form. Focusing on the outer form sometimes causes the writer to tend to words the formation with an inexcusable excess and to fail to express meaning. Therefore in contemporary criticism، the study and analysis of technics of innovations that theauthor uses for postmodernism meaning making uses for postmodernism meaning making have been at the center of attention.The purpose of this article is to examine the innovative semantic tricks in Amirkhani's "Bivatan". Based on this, recognizing the type of forms and novel forms used in “bivatan” and their effects on the meaning and deepening of content have been the main questions of this research. Examining the elements of the forms and analyzing their roles in highlighting the themes of the story shows that Amirkhani's method was not merely apparent modernization, and he gave a special and thought-provoking depth to the content of the text by dynamically defamiliarizing and highlighting the form.

Our intention of music in this article is an extensive meaning namely form and construction. For a more detailed study of the subject, both of them from four direction has been investigated: 1- External music or prosody, 2. Side music or Rhyme and row 3. Internal Music or figures of speech, rhetoric and linguistic structures 4. Contemplative music or structures of fiction and description. With statistical presentations and analysis of them, distinguished that Ferdowsi's verses in four directions had more integrity, variety, expansion and high literary value. Verses, rhyme and rows of Ferdowsi are more various, musical and artistic than Daghighis verses. In figures of speech Daghighi has been more attentions to apparent of speech and rhetoric and Ferdowsi to depth of speech and intellectual relationships. In saying stories Daghighis verses compare to Ferdosis verses are more strictly speaking, more direct and more ambiguous and older but Ferdowsis narrations are mor realistic, multi-dimensional, more detailed, with more subtlety, and creating more attractive.

Among the various mystical works that have investigated these concepts is On the reality of Love (Fi Haghighat Al-Eshgh) which is a unique work. In this work Suhrawardi has characterized abstract concepts such as love, wisdom and goodness and has created a mystical and philosophical story. After him, many poets and writers have begun to imitate his work and created similar works .One of these is Fozouli's Health and Disease (Sehhat va Maraz). Given the similarities between the two works is the application of reason and good and love we considered and compared these concepts in these two treatises. Fozouli has paid more attention to the mystical meaning of these concepts; Suhrawardi has also considered the philosophical dimension of them. The reason has different meanings in the two treatises; but love and goodness have really close meanings. Manuscript profile -

The method of research is descriptive-correlational and its performance method is survey. The statistical population of the research consists of all female teachers in governmental and nongovernmental high schools of Kermanshah. Convenience sampling was used in this research to determine 286 teachers as the sample of study with regard to the total population (N=1000) and based on the Cochran formula. The research measurement instruments included three questionnaires of Public Health (Goldenberg), Adults' Resilience Scale for Adults (Friborg et al.), and Job Satisfaction (Kendall & Hulin). The validity of the questionnaires was confirmed by the experts and their reliability was calculated to be 95%, 89%, and 93% respectively. For data analysis, descriptive statistical methods (frequency, percentage, average, and standard deviation) and inferential statistics including correlation and regression were used. The results showed that there is a negative and significant relationship between components of resilience (personal qualification, social qualification, social support, family integrity, and personal structure) and mental health signs. Furthermore, a negative and significant relationship was observed between aspects of job satisfaction (occupation, supervisor, and colleagues) and mental health signs while there was no significant relationship between aspects of promotion and payment. Regression analysis results revealed that among predictor variables, the variables of personal qualification, social support, and personal structure have the potential to predict mental health symptoms. With respect to the research findings, the managers can have a positive impact on the betterment of their employees' resilience and job satisfaction. Manuscript profile -

Moreover, by properly using the capabilities of FinFET technology, the number of transistors is reduced, and subsequently, a smaller area is occupied. Replacing MOSFET transistors with FinFETs reduces the delay and power consumption of the circuit, so the overall performance is improved. The first innovation of the proposed design is that to reduce the size and power consumption, two transistors were removed and the back gates of two transistors were cross-coupled. The second innovation is the connection of back gates to other suitable points of the circuit that increase the speed of comparison. In this study, a supply voltage of 0.8 V is applied to the circuit to show that the proposed modifications with FinFET reduce the delay to 272 ps and power consumption to 6.7 µW. Manuscript profile -

Hence, using 32 nm carbon nanotube field-effect transistor (CNTFET) technology and relying on Toffoli's reversible gates, a new full adder (FA) circuit is presented. The proposed circuit has 4 basic Toffoli gates and 18 transistors. 3 of the 4 gates have the same transistor schematic with a constant-ON transistor, but the remaining gate has only two transistors. The proposed circuit has 3 constant inputs and 4 garbage outputs. As a new method, in the proposed circuit, only one type of reversible gate is used. The results show the superiority of the proposed FA in terms of power consumption and energy dissipation. By implementing the proposed FA and other circuits in a 4-bit and 8-bit ripple carry adder (RCA), the proposed circuit shows improvements by 6.83% and 11.25% in terms of power and energy, respectively, compared to the main competitor. Also, in an 8-bit RCA, the proposed FA has a 2% saving compared to the nearest competitor and 27% compared to the worst circuit in terms of the power-delay-area-product (PDAP). These results show the designed FA as a favorable option for complex structures with high-order bits. Manuscript profile -

The population was 480 students and the research method was a descriptive survey. For this purpose, 100 students from the regular and 100 students from the gifted high school were selected by using random sampling. Personality characteristics were measured by Personality Inventory for Adolescents (Eysenck, 1990), and Goldberg Mental Health Questionnaire was used to assess the mental health. Data analysis based on multivariate analysis of variance and Pearson correlation coefficient showed that, there were significant differences between gifted and regular students in personality characteristics of neuroticism and lying (P<0.001) and significant difference appeared between mental health and all its levels except social functioning (P<0.05). The correlation coefficient between neuroticism, aggressiveness and lying with mental health was significant in the gifted students. Also the correlation coefficient between aggressiveness and lying with mental health (r= -0.4) was significant in the regular students. The present study showed that lying and neuroticism, among regular school students were more than gifted school students. Moreover, gifted students had higher mental health in the subscales of physical symptoms and depression.

The research was a semi experimental, pretest- posttest with control group. The population composed of all girls in secondary schools of Ilam in 1392 among whom 180 students were selected by simple random sampling and the Conflict Behavior Questionnaire CBQ (Prinz, 1979) was administered to them. Then 48 students who had higher conflict scores with their parents were selected and assigned to the two experimental and control groups based on simple random sampling. Then, the experimental group was separately divided into triple groups (father, mother, and the student herself) and the control group (12 subjects) was assigned for all three groups (12 subjects). Each group participated in a 8-session training course. In the end, the post-test of the same Conflict Behavior Questionnaire CBQ (Prinz, 1979) was administered to both groups. The data were analyzed by covariance statistical analysis test and the findings showed that teaching proper communication techniques to parents and children, to a great extent, is influential in decreasing the intensity of conflict between parents and children. Also, there was a significant difference between the mean of the post-test scores of experimental and control groups implying that in the experimental groups the conflict has decreased considerably.

The sample consisted of 351 females who were selected by random clustered sampling from high school students in Alborz province. Research instruments were the NEO Personality Inventory (MacCrae and Costa, 1985) and Self-efficacy Scale (Sherer at.al, 1982). The result showed that conscientiousness of mothers was the only predictive variable which could predict daughters' self-efficacy. Regression coefficient of self-efficacy (&beta=0.226) showed a positive relationship between mothers conscientiousness with their daughters self-efficacy (P < 0.002). Also the average score of girls with regression coefficient (&beta=0.330) represented a significant and positive correlation and their self-efficacy (P < 0.0001), and maternal age with regression coefficient (&beta=-0.105) indicated a significant and negative correlation with daughters’ self- efficacy (P < 0.37). Therefore, considering the effect of both mothers’ role of responsibility and low maternal age gap with daughters on the self-efficacy of their daughters, it is necessary to increase self-efficacy of daughters by enriching the responsibility resources of mothers and encouraging mothers to have children at young age.

The statistical population included all male high school students in Kermanshah in the academic in 2020-2021, which was 234 students who obtained the highest scores in the pediatric symptoms questionnaire (parent form) (Gadow & Sprafkin, 2007) and They had the most symptoms of conduct disorder, were selected as a sample group based on multi-stage cluster sampling method, and participants completed the Alabama΄s parenting styles (Frick, 1991), the Baron-Cohen empathy quotient scale (Baron-Cohen & Wheelwrigh, 2004). Structural equation modeling on LISREL software was used to answer the hypotheses. The results of data analysis showed that direct and indirect path coefficients are significant in the research model (P <0.001). According to the findings of this study, efficient and inefficient parenting styles and emotional and cognitive empathy have a direct and significant effect on conduct disorder and efficient and inefficient parenting styles also have a direct and significant effect on emotional and cognitive empathy. Also, effective parenting style (positive parenting components and father participation) and inefficient parenting style (components of authority, poor supervision and corporal punishment) mediate emotional and cognitive empathy on students' conduct disorder indirectly. Based on the results of this study, it can be concluded that proper communication between parent and child enables the person to achieve emotional development and increases the ability to empathy and community friendly behavior in adolescents.

The research design was descriptive-correlational through structural equation modeling (SEM). The statistical population of the study included all high school students in Ahvaz in the academic year 2020-2021 (In total, 49,744 students). From this population, 850 students were selected by the multi-stage cluster sampling method to test the research hypotheses. The instruments used in this study included the Gross and John’ Emotion Regulation Scale (2003), Sukhodolsky et al.’ Anger Rumination Scale (2001), Thompson and Zuroff’ Levels of Self-Criticism Scale (2004), Neff’ Self-Compassion Scale (2003), Bond et al.’ Acceptance and Action Questionnaire (2011), and Weitzman’ Social Development Scale (1990). The goodness of fit of the proposed model was examined through structural equation modeling (SEM), using SPSS-24 and Amos-24 software packages. The indirect effects were tested by the Bootstrap procedure. The results showed a good fit of the final model with the data. The results showed that emotional regulation, anger rumination, and self-criticism have direct effects on students' social maladaptation (p<0.05). The findings also showed that self-compassion and psychological flexibility mediate the effects of predictor variables on social maladaptation (p<0.05). According to the research results, emotional regulation, anger rumination, self-criticism, self-compassion, and psychological flexibility are the most important variables affecting adolescents' social maladaptation that should be considered when formulating and implementing interventions.

The statistical population included students of Arak city who were studying mathematics, experimental and humanities in the Second Period public high schools and were selected by multi-stage cluster sampling method. The number of sample people was considered as 719 students, considering the probability of failure in completing the questionnaires. Data collection tools included Academic Boyancy Questionnaire (Dehghanizadeh & Hossein Chari), Academic Self- handicapping (ASHS) ( Schwinger & Stiensmeier-Pelster), Multidimensional Students’ Life Satisfaction (MSLSS) (Huebner) and Adolescent Perception of Parenting Educational Methods (POPS)( Robbins). The obtained data were analyzed by the structural equation model of latent variable type. In order to verify the model's fit, the values of the ratio of chi-square to degree of freedom, (RMSEA), (CFI), (NFI), (TLI), (IFI) and Cronbach's alpha were reported that indicate appropriate model reliability. Findings showed that buoyancy and academic self- handicapping have a direct and significant effect on life satisfaction and adolescent perception of parenting educational methods. The direct effect of the mediating variable on life satisfaction was also confirmed. By doing this research, by observing educational problems or lack of mental health and identifying the factors affecting it in students, appropriate programs can be implemented to increase life satisfaction in students.

Statistical universe In this research were full-time faculty members of Islamic Azad University Kerman Branch 2008-09 (N=620). Of them, 175 were selected using a relative random sampling. Tools used in this research were two researcher-made questionnaires. Reviewing the literature and research background, 54 variables and sub-components were extracted accordingly, the first questionnaire was compiled to determine the status quo of social capital. The content validity of the questionnaire was confirmed and approved by clear-sighted people and its reliability was, after performing the test among some of the faculty members, calculated using Kronbach Alpha (98%). Data analysis was done at two descriptive and deductive levels (correlation coefficient and factor analysis). After factor analysis was finished, 7 main components and 54 sub-components (namely organizational identity, capability making, cooperation and public benefit, knowledge sharing and creating intellectual capital, trust and correlation, cooperative management and awareness) were recognized. The Results revealed that the main components of trust and correlation had the highest average and components of cooperative management had the lowest one. The Sub-components of commitment and belonging, leadership power rate and management, benevolence, generosity, creating relationship between knowledgeable people and those who need their knowledge, accessibility to required people and groups had the highest average, while the sub-components of glorification and appreciation, justice, tendency toward collective objective, fostering innovation and creativity, correlation in the entire organization and cooperative management had the lowest average, reflecting undesirable conditions in these areas. The results also showed that there was no significant difference between the respondents' opinions concerning variables of sex, education and working record. There were some differences, however, regarding the variables of scientific rank and university location regarding scientific rank, the highest social capital was related to (professors) and the lowest to teachers. Also, concerning the place of service, Zarand Town and Kerman City had the highest and lowest social capital respectively. According to findings of the first questionnaire, the second one was compiled in 5 parts (philosophy and objectives, theoretical fundamentals, perceptual framework, executive steps and evaluation system).

A diagnostic test comprising six questions with multiple-choice format was used to collect the required data. To ensure the content validity of the instrument, a panel of 20 teachers of physics verified the questionnaire. The reliability was confirmed by Cronbach's alpha as 0.87.The test was given in a normal condition with no in advance awareness. After the test was run, the frequency, frequency percentage, the tables and corresponding graphs were used. To assess how well students understood, the conceptual evaluation method was applied. In this method, the options were categorized in four types as: full understanding, partial understanding, misunderstanding and lack of understanding.The findings showed new misunderstandings about the concepts of static electricity. Based on these findings, it seems so necessary that physics curricula and instructional materials which are about to be recently revised by the Ministry of Education be taken into more considerations so as to organize the concepts of static electricity and its modeling in related textbooks.

The research method was of quasi-experimental type, using pre and post tests for two experimental groups. Amongst the junior high schools, in Shiraz, one boy school and one girl school were selected by randomizing. Then, in each school, two classes were selected randomly, too: one as an inductive experimental group and the next class as a deductive group. Measurement test was of the thirty -questions test about comprehension and grammar. Since this test was standardized, its validity and reliability had been confirmed the first by some teacher, professors, and head teachers in Shiraz educational organization and the second by Coronbach’s Alpha as %76. The experimental groups, then, have been taught both inductively and deductively. In the end, post-test was given to these four groups. By Using co-variance analysis and an independent group t-test, data, then, have been analyzed. The findings showed that experimental groups were significantly different in that, the scores of students, being inductively taught, were better than those of deductive one. Regardless of the last hypothesis saying that there is a significant relationship between boys and girls in comprehension, in deductive method, most hypothesis of this research have been verified. It is, therefore, concluded that inductive method is much more effective than the deductive one. Considering the coming hypothesis, it is to say that this very method has been more effective on the girls however, in the last hypothesis, this relationship is not significantly meaningful. What being resulted, therefore, is that, generally, inductive teaching method is so beneficial in English learning. Manuscript profile -

Statically, population consists of all private and governmental higher education institutions (non-governmental universities, Islamic Azad University) in the Islamic Republic of Iran and to make an in-depth examination and thorough census was conducted. On the other hand, evidence shows that during the two last decades, governmental facilities and budgets could not respond to it. Thus, establishment, development and tooling of private and non-governmental universities and institutes, that the great part of it is Islamic Azad university, attracted considerable attention and growth. Hence Islamic Azad university students outnumber others (Bazargan, ). With respect to the sensitive role of this section, careful knowledge about its potentials and as well as planning for the future, is very crucial. Thus, in this research, primarily, the backgrounds of establishment and trend of private higher education development in some countries was discussed and then with the presentation of a short history of private higher education in Islamic Republic of Iran, we investigated the trend of growth in Iranian private and governmental higher education institutes.

We propose an examine use of Motahari educational ideas about socialization in textbooks. Motahari, as an intellectual leader, has an important role in explaining basic concepts of Islamic revolution of Iran. Motahari’s books and high school social sciences textbooks as statistical society and on census method, were studied based on paragraph unit analysis. We applied a mixed method of content analysis. For discovering components of socialization, we used qualitative method for content analyzing of Motahari’s books and find four components: social belonging; social responsibility; dialogue and communication, and critical thinking that extracted from thirteen categories. Then, by using a coding frame based on these components and categories, we use quantitative content analysis to obtain if these used in the social sciences textbooks based on exploratory factor analysis. Results show that there aren’t these components in many lessons of textbooks. Some of these results related to the educational aims of these books, because in these textbooks, students introduce with sociology discipline; but some related to weakness of consideration.

The participants in this study were 140 teachers (males=87,females=53) at secondary schools in Garmsar. Two instruments were used to collect data. The teachers' instruction procedure was measured by the use of a researcher made questionnaire (with three dimensions of instruction as direct, semi‐direct and indirect). The job burnout (namely: emotional exhaustion, depersonalization and decreased professional efficacy) was measured by the Maslach Burnout Inventory (MBI). The data were analyzed using the Pearson product‐moment correlation technique, Chi‐Square test and regression. The major findings were as follows: 1) A signiicant relationship between total teachers' nstruction procedure and total burnout. 2) A positive relationship between teachers' direct instruction procedure and job burnout. 3) A Negative relationship between teachers' indirect instruction procedure and job burnout. 4) No significant relationship between teachers' semi‐direct instruction procedure and job burnout. 5) A positive relationship was found between teachers' direct instruction procedure with each three dimensions of job burnout (Emotional exhaustion, depersonalization and reduced personal accomplishment). 6) A signiicantly negative relationship was found separate between teachers' direct instruction with each dimension of job burnout. 7) There was no relationship between teachers' semi‐direct instruction procedure with each three dimensions of job burnout.

The aim of this article is to study and compare the efforts made by curriculum planners in different universities around the world for the internationalization of the higher education. This comparative – analytical study investigates different approaches for the internationalization of curriculum of the higher education (including strategies, programs, activities and methods of teaching and learning) in countries like the United States of America, Canada, Australia, and Japan. Findings include strategies, programs, activities for internationalization of higher education curriculum learning and teaching methods in each country. Comparison of four strategies of the United States, Canada, Australia, and Japan showed that internationalizing the curriculum and learning strategies by embedding international content into their existing curricula is their most important strategy and teacher and student exchange programs receive less attention. Today, the internationalization of local and national curricula is of great importance. Manuscript profile -

These elements are of seven types as: Human Right and Democracy, Cooperation and Solidarity, Preservation of Cultures, Self and others, Internationalism, Protection of the Environment and Spirituality. The present study is one of descriptive and content analysis type. The data-collection tools in the first part include checklist. In second part teacher behavior observation checklist was used which was researcher-made checklist and its validity and reliability have been confirmed. The research sample, in the first part, includes all the contents of Social science, Persian literature, and Theology and History books in the three grades of junior high school. In the second part, based on stratified random sampling, 60 social science classes in Uremia schools were chosen for the study. For the content analysis, Shannon Entropy Method is used and descriptive and inferential statistics of T-test and variance analysis are used to analyze the implemented curriculum data. The results in content analysis part show that UNESCO peace education elements, in the above –mentioned books, are not, too much, taken into account. The most field of attention is on Cooperation and Solidarity elements which are most frequent in Social science books and least frequent in History books. The least attention, however, is paid to democracy and nature protection which in social and religious books, it is possible to keep track of them but we cannot say the same for literature. The Teacher behavior observation checklist results show that teachers function, lower than average in teaching-learning skills regarding teaching peace.

This study is based on the purposeful sampling of selecting the desirable cases and until saturation eighteen teachers (7 males and 11 females) were selected in which we would continue sampling to reach cases which no new information would be obtained. The teachers were semi-structured interviewed and they were analyzed by content analysis method. The validity and reliability of the instrument were verified using reliability, portability, verifiability and reliability. The results of the study showed that they do not accept the self-examination method as a valid method for evaluation and they do not take seriously the using of the portfolio. This study showed that the tacit knowledge of high school English language teachers in qualitative evaluation methods does not form a significant amount of tacit knowledge of teachers and their confidence in qualitative evaluation is low. Many teachers use quality evaluation as an adjunct to objective evaluation and to improve the learning process, and do not see quality evaluation as a serious method of evaluation.

Based on the four main processes of generative theory (motivation, learning, meaning making, generation), a checklist was developed. Four experts in TEFL and 21 English teachers were asked to analyze 9 selected lessons from the books. The content validity of the checklist was confirmed by the 4 experts and the intra- and inter-rater reliability indices showed a significant reliability level. Then, interval evaluation was used for the analysis of the obtained means. The results showed that the textbooks were evaluated as successful according to the generation criterion, moderate regarding meaning making criterion and weak in terms of learning and motivation criteria. Furthermore, the books were evaluated as weak regarding their generalizability power to non-learning contexts (which is an important aspect of communicative approaches) as well as motivation, developing thinking skills and raising awareness and attention criteria. Some suggestions are made for the improvement of generalizability of learning to out-of-class contexts, thinking skills and motivation in texts, exercises and tasks. Manuscript profile -

The present qualitative study was carried out with a phenomenological approach in the fall of 2018 on 21 English language teaching and training specialists through purposeful sampling and data saturation. This study continued with the confidentiality of the information and the possibility to leave the study at any time. Data were collected through semi-structured interviews. The method of analyzing the findings of this study was based on three codings: "open", "axial" and "selective". Interview data was read several times in an active and interactive way and then coded openly. After the open coding, the data came together based on the common axes that emerged between them and their abundance. Axial codes were then incorporated into themes based on similarities and inconsistencies. Frequency and percentage of each axial code were calculated. By analyzing and integrating the principal components, two principal components were identified and 28 sub-components were extracted by principal component analysis. The results show that among the sub-components derived from the analysis of the responses of English language education and training specialists, the most important method for teaching English is to enhance the motivation of learners to learn English through different ways by teacher in the first grade of high school.

This phenomenon has arisen due to organizational and individual circumstances (Causal Conditions) and resulted in reactions such as avoidance, conflict (Strategy). These reactions have been affected by the responses of the authorities, the persistence and common beliefs (intervening conditions), structure and academic culture (context), resulting in occupational, personal, social and economic vulnerability(Consequences). The function of education in this context is defined in three levels of good teaching (based on individual experience), scholarly teaching (based on the integration of content knowledge and pedagogy), and the scholarship of teaching (Teacher Education Publishing). From the faculty point of view, according to the phenomenon of bullying, teaching processes based on personal experience are organized, teacher empowerment and dissemination programs are not foreseen.

The research was conducted in a heuristic (qualitative-quantitative) mixed paradigm. In the qualitative part, studying and identifying the areas of global citizenship education in the academic curriculum in Iran were considered. Thematic analysis was used on two levels of electoral documents and headings approved by the Supreme Council of the Cultural Revolution. Data were collected through content analysis, checklist and checklist. Document analysis was used to analyze the data. In the quantitative section, a descriptive survey method was used and the statistical population of the program was 145 people. The researcher-made questionnaire was designed with Cronbach's alpha coefficient of 0.91 and content validity. Chi-square and Friedman tests were used for data analysis. According to the findings in the qualitative part of the general curriculum system, its focus and organization is based on the discipline-based normative approach. Most of the content related to the components of globalization is often indirectly related and is dominated by positive, neutral and negative aspects. Therefore, the Global Citizen Curriculum Model is based on an interdisciplinary approach in five key steps that include the key elements of the program. The course (Goals, Content, Teaching and Evaluation Methods) was designed based on three components of knowledge, skills, and attitudes at both macro and micro levels. At macro level, the integrated curriculum approach (integration) and at the micro level (vertical, broad and educational) used. Manuscript profile -

For this reason, the existence of curriculum templates can help university professors and curriculum planners in designing and compiling curricula in a way and in making decisions. The model in the development of university curricula is interpreted as a detailed plan to achieve the goal. For this purpose, the present research has been conducted with the aim of examining the curriculum patterns of higher education in Iran. The above research has been done with a systematic literature review and qualitative content analysis technique (theme analysis) among sources and documents collected from scientific databases. The results of the research show that the focus of the researchers in providing models was mostly on Tyler's four elements and less on the nine and ten elements of the curriculum, and the macro dimensions of the curriculum in higher education have been neglected. Designing the proposed models (providing the framework) is one of the important activities of curriculum planners and decision makers, and university educations are also forced to design and implement the proposed models (determined frameworks) of the curriculum. But the focus of attention that researchers should pay more attention to is the extent of attention to the larger dimensions of the curriculum and not the elements and content of the curriculum.

To achieve this purpose, the opinions of three groups were studied including the senior managers in government, the figures and experts in the field of planning and management, and administrative managers and employees. The last two groups were selected using judgment-sampling method. The research method was "applied research" in terms of purpose and so it was "content analysis", "survey research", and "correlational research" in terms of data collecting method. In addition to the review of the related literature, the desired data was gathered by analyzing the interview transcription of the senior managers as well as questionnaires. Descriptive and inferential statistics were employed to analyze the data and draw conclusions. According the findings, the obstacles to executing the development plans in the higher education system originate from its functional structure. The obstacles include: the lack of conformity between the structure and the particulars of the development plans, between the structure and the environment in which the plans carried out, and between the structure and the plans goals, which all resulted from functional structure of higher education system and its limits. Finally three strategies are proposed to overcome the structural obstacles to executing the development plans in the higher education sector. In order of importance, these strategies include participative culture, systematic or synthetic management, and matrix structure. On the basis of regression model, the proposed strategies have correlation with each other and play an effective role in removing the obstacles. Manuscript profile -

In similar conditions, the challenges of education and problems after graduation in the fields of science, technology, engineering, and mathematics (STEM) are more obvious. Although today there is a large amount of research on how to deal with the issues related to the quality of education, these methods were generally not successful and most of those who finish a degree in the university, are usually unprepared. They are not required to enter the labor market. In this article, a hybrid method called HEAL is introduced, which is especially effective in STEM education. This proposed approach can be considered a combination of teaching and learning and is a transformation that leads a person from being a mere student to becoming an active learner. The main idea of this approach is based on the fact that in university, a student is expected to be a researcher of knowledge, unlike a student who acquires knowledge through education.Method: hybrid education and learning (HEAL) is a skill-based, time-based method of instruction that combines face-to-face learning and virtual learning. Proficiency-oriented, time-based education provides a model in which students who fail to earn a passing grade or complete a course during a semester are given time to demonstrate competency.Findings: The basic philosophy of HEAL is to prove the skills and abilities of students, with an approach similar to the driver's license test. This means that if the test is failed, the learner is given an opportunity to improve and try another way to demonstrate mastery. The financial capability of universities is the most important factor in making this approach operational. However, this financial burden is negligible compared to course repetition, delayed graduation, and sometimes even more academic failure. HEAL removes the fear of exams and failure and increases the love of learning.Discussion: The combination of face-to-face and virtual learning can become a wider trend in the university. While we must remember the fact that nothing can replace face-to-face training and the need for student-faculty interaction. In this research, a method for teaching in universities was discussed, in which time-based and competency-based education are combined with face-to-face and virtual learning, which can be a successful approach with the aim of reducing academic retention.

This research aims to evaluate the effect of a cafeteria diet on the density of dendritic spines of hippocampal and striatum neurons from the end of infancy to the beginning of puberty. Materials & Methods: 22-day-old male and female Wistar rats that passed through infancy were randomly divided into two control and cafeteria groups (n=6). The control group had access to standard rat food, but the cafeteria group received a cafeteria diet in addition to standard food for up to 30 days. During the treatment, the rats of both groups were weighed every week. After five weeks after the start of the treatments, the brains of the mice were extracted and prepared for Golgi staining by the Rapid Golgi method. Results: Our results showed that the body weight increased significantly in the cafeteria group compared to the control group (P<0/01). In addition, the results showed that the cafeteria diet significantly reduces the density of dendritic spines in the hippocampus (P<0/01) and striatum (P<0/05) compared to controls. Conclusion: According to the results of the present study, the reduction of dendritic spines in the hippocampus and striatum, two important structures in cognitive behaviors, may cause memory and learning disorders observed in people consuming a high-fat diet.

The soft switching condition is provided for switch in turn on instant, so the converter efficiency is high. Due to the fact that only the capacitor is used to increase the voltage gain and there are no coupled inductors in the converter, the input current of the converter is continuous. The technique used to increase gain can be used with more stages to achieve higher voltage gain. The converter can also be used as a single input intertwined instead of two inputs, which in this case the input current ripple is reduced. The voltage stress on the switches is lower than the output voltage, so lower voltage switches can be used, which reduces the converter cost. The proposed converter is completely analyzed and in order to prove the theoretical results, a simulation is performed on the converter at 500 watts. The results of the simulation at full load show an efficiency of about 95.5%. Manuscript profile -

These converters can be used in applications of power systems based on wind, photovoltaic, hybrid vehicles, etc. In a multi-input system, usually one of the inputs is connected to an AC source. Also, these converters use soft switching techniques to increase efficiency. In this paper, a non-insulated dual input soft-switching boost converter with power factor correction capability is proposed. This converter uses only an auxiliary circuit with simple operation. The operation modes of the proposed converter are described. All of the semiconductor elements in this converter turn on and off in soft switching conditions. The proposed controller circuit is presented with power factor correction capability. The converter is simulated with PSIM and THD and PF shows that the power factor correction in AC input is occurred correctly. The efficiency of the proposed converter is increased in comparison with the multi-input hard switching converter under the same conditions. The simulation results with PSpice for a 200-watt prototype converter confirm the theoretical analysis. Manuscript profile -

There are soft switching conditions in the proposed converter for switching on and off time, which increases efficiency. In order to increase the gain, two coupled inductors have been used, and the leakage inductance of the coupled inductors has been used to create a soft switching condition, and the minimal auxiliary element has been used in the proposed converter. In the proposed converter, only one switch is used, and the condition of the converter is no different from a basic converter in terms of the control circuit. Therefore, the converter does not need to design a new control circuit. The auxiliary circuit added to the converter with a minimal element, provides soft switching conditions for the switch at turn-on, under zero current and at turn-off, under zero voltage, which, in addition to increased efficiency, the circuit has a simple structure. Therefore, the innovation of the paper is to present a switching converter high step-up soft without imposing an additional switch and with a low number of elements. The proposed converter is simulated after full theoretical analysis at 400 W output power, which shows the efficiency of 97.2 percent, in addition to proving the theoretical analysis. Also, the prototype of the converter is made and the experimental results obtained prove the theoretical and simulation results. Manuscript profile -

Cascaded boost converters provide more voltage gain than single boost converters, but they are still unsuitable for high step-up voltage conversion due to gain and hard switching conditions. To improve the voltage, gain of the cascaded boost converter, a coupled inductor can be used but the leakage inductance causes a voltage. To overcome these problems, a high step-up converter is proposed in which a cascaded structure, coupled inductor, and a lossless passive snubber are utilized together. The proposed converter has zero current and zero voltage switching conditions at turn-on and off instants. First, the proposed converter is theoretically analyzed, and then its design and simulation in OrCAD software are presented. Furthermore, the experimental results of the prototype verify soft switching conditions and high step-up gain. Manuscript profile -

The proposed converter consists of two switch cells that their inputs and outputs are cascaded. This converter provides ultra-high step-down conversion ratio and due to all semiconductor devices are soft switched, switching losses are reduced, also reverse recovery losses of diodes are reduced because of ZCS turn off condition. The duty cycle of proposed converter is much larger than step-down converter and therefore does not have the problems of the converter with a narrow duty cycle and since no auxiliary switch is used to achieve soft switching, the control circuit remains simple. In this paper, the convertor operating modes are discussed and to verify the performance of the converter a 50W prototype with 100 kHz switching frequency, 100V input and 16V output is built. The converter efficiency is measured and the peak efficiency is 94% also the conducted electromagnetic interference peak in the proposed converter is reduced by 6dBµv. Manuscript profile -

A part of his existence pertains to the light and the other part to the world of darkness. Lights and darkness allegory and man's place among both of them are symbolically addressed. Body and soul, wisdom and ego, goblet and light or goblet and wine as well as mirror and felt are of the most major titles of allegory. Man and woman are another expression in order to show the reciprocal symbols of light and darkness in the creation domain; an allegory which can also be seen in the other cultures and religions. In addition, woman herself has a dual face. On the one hand, she is the symbol of darkness against man, and on the other, she is the symbol of real light that is, absolute reality. It is seems that, man's duality is influenced by an extensive argument entiteled "Haghighat – e Mohammadiyeh", because the inherent concept of Haghighat-e Mohammadiyeh, in which mankind is proposed to be the most significant evidence, is per se a dual concept that plays the intermediate role.

The current research, which is of a descriptive-analytical type and was prepared using a survey method, while identifying the effective factors in spatial attachment including "form-physical", "perceptual-emotional" and "activity-functional" and ranking them It deals with the level of residential satisfaction. These components in the formal-physical index include the components of "presence ability", "desired quality", "suitable density", "collective spaces" and "indicative places", in the perceptual-emotional index including the components of "duration of residence". "marital status", "personal income", "gender" and "occupation". The components of "memorable local events", "social interactions", "special activities", "suitability of activity to needs" and "cooperation" are also included in the sub-components of the activity-functional factor. The case study of this research is the Aseman residential complex in Tabriz, and its statistical population consists of the residents of this complex. The results of the surveys show that the perceptual-emotional factor with an average score of (3.610) and the formal-physical factor with an average score of (2.932) had the greatest and least impact on creating attachment to a place, respectively. The components of "presence" (3.02) from the formal-physical factor, "duration of residence" (3.73) from the perceptual-emotional factor and "memorable local events" (3.62) from the activity-functional factor have the highest score. among the relevant sub-components. Also, the findings show that there is a significant relationship between the effective factors in creating attachment and people's satisfaction with living in high-rise buildings. This means that the higher the quality of these components and the higher the level of people's understanding of them, the greater the attachment to the place. In proportion to this promotion of the sense of belonging in people, their level of satisfaction with living in high-rise buildings increases. According to the findings of the research, it is suggested that architects, designers and urban planners in the design of residential complexes, all the effective indicators on creating spatial attachment, including physical (form and composition, natural elements, lighting, visibility and access and ...), activities (social welfare, commercial, recreational and transportation services, diversity of activities, etc.) should be taken into consideration more in advance and provide the basis for the positive impact of individual and social indicators in order to achieve satisfaction. Residents will increase from living in high-rise residential complexes Extended Abstract Introduction: As one of the important indicators of sustainable urban development, the housing category, if unhealthy, endangers the health and quality of life of a wide range of people in the society and consequently the health of the city. Regarding high-rise buildings and their level of satisfaction, many researchers believe that one of the effects of living in complexes with high population density and unfavorable environmental quality is the weakening of social ties between residents, which itself is the basis for reducing stable communication, non-participation, decreasing the sense of belonging and gradual deterioration of these collections. High-rise construction is one of the methods of providing urban housing, and nowadays, the examination of their responsiveness in providing the quality of life for residents has been more and more noticed by designers and researchers. In Iran, residential complexes in different forms are used as a solution to provide housing, but the examination of the response rate of these complexes to ensure the quality of life for the residents has not been given much attention. Measuring housing satisfaction is complex and depends on many factors. Regarding high-rise buildings and their level of satisfaction, many researchers believe that one of the effects of living in complexes with high population density and unfavorable environmental quality is the weakening of social ties between residents, which itself is the basis for reducing stable communication, non-participation, decreasing the sense of belonging and gradual deterioration of these collections. Given that satisfaction, like human nature, is a complex phenomenon with diverse and different indicators, in the present research, the effective factors in place dependence and satisfaction of citizens from living in high-rise buildings were investigated. The factors influencing the creation of a sense of belonging to a place can be considered to be caused by the person and the surrounding environment (with all its characteristics). This is the case with the factors of the "environmental" and the factors that are affected by the social factors, and the social factors. Local cooperation and local visas create memories, etc., and personal factors include mental images and personal characteristics, etc. Such as mental images, satisfaction, security, relationships, expectations and previous belongings, and personal characteristics have the factors of job, type of residence, reference culture and length of stay. Methodology: The current research, which is of a descriptive-analytical type and was prepared using a survey method, while identifying the effective factors in spatial attachment including "form-physical", "perceptual-emotional" and "activity-functional" and ranking them It deals with the level of residential satisfaction. These components in the formal-physical index include the components of "presence ability", "desired quality", "suitable density", "collective spaces" and "indicative places", in the perceptual-emotional index including the components of "duration of residence". "marital status", "personal income", "gender" and "occupation". The components of "memorable local events", "social interactions", "special activities", "suitability of activity to needs" and "cooperation" are also included in the sub-components of the activity-functional factor. The case study of this research is the Aseman residential complex in Tabriz, and its statistical population consists of the residents of this complex. The questions raised around each indicator were prepared and completed by the statistical community based on the five-point Likert scale. In order to determine the validity of the questionnaire, the content validity method was used qualitatively. The reliability of the questionnaires was also evaluated using Cronbach's alpha calculation method equal to (0.876). Finally, the collected data were processed with SPSS software at two levels of descriptive and inferential statistics and analyzed with Pearson's correlation coefficient test. Results and discussion: The results of the surveys show that the perceptual-emotional factor with an average score of (3.610) and the formal-physical factor with an average score of (2.932) had the greatest and least impact on creating attachment to a place, respectively. The components of "presence" (3.02) from the formal-physical factor, "duration of residence" (3.73) from the perceptual-emotional factor and "memorable local events" (3.62) from the activity-functional factor have the highest score. among the relevant sub-components. Also, the findings show that there is a significant relationship between the effective factors in creating attachment and people's satisfaction with living in high-rise buildings. This means that the higher the quality of these components and the higher the level of people's understanding of them, the greater the attachment to the place. In proportion to this promotion of the sense of belonging in people, their level of satisfaction with living in high-rise buildings increases. In the interpretation of these findings, it can be pointed out that the satisfaction of citizens has a deep relationship with a person's understanding and feeling about an object, subject, place, etc. Events, images, people and belongings in an environment create a memory and mentality in a person and cause feelings such as happiness, enthusiasm, sadness, sadness and memories in a person, which is associated with the creation of attachment. Form-physical factors as well as activity-functional factors, although each of them has some kind of effect in creating a memory and place attachment, but considering that the form-physical factors undergo changes over time, such as additions, colors and lighting, etc. and the activity-functional factors also cause the removal and addition of some activities by changing the use and converting some spaces into future needed spaces to other factors. Conclusion: In a general summary and according to the findings of the research, it can be concluded that all three mentioned factors had a positive effect in creating a sense of belonging and place attachment, but the effect of perceptual-emotional factors was better. So, It is suggested that architects, designers and urban planners in the design of residential complexes, all the effective indicators on creating spatial attachment, including physical (form and composition, natural elements, lighting, visibility and access and ...), activities (social welfare, commercial, recreational and transportation services, diversity of activities, etc.) should be taken into consideration more in advance and provide the basis for the positive impact of individual and social indicators in order to achieve satisfaction residents will increase from living in high-rise residential complexes.

403 - A new look at the function of the street: providing a conceptual model of High Streets for All approach (Case Study: comparing Imam Khomeini Street and Foroughi Street in Tabriz)
Mana Vahidbafandeh Javad Imani Shamloo Melika Fadavi The high and main streets of the city are the heart of cities nowadays. Today, these vital arteries are facing new social, environmental and economic challenges and must deal with the uncertainty of the city. Now the impo More The high and main streets of the city are the heart of cities nowadays. Today, these vital arteries are facing new social, environmental and economic challenges and must deal with the uncertainty of the city. Now the important question is how to design and plan the main streets of the city in such a way that it meets the different expectations of society and at the same time, it can be compatible with future developments. Many planners and urban designers in the world are thinking of creating strategies to restore the role of high streets to their original position as a place to serve visitors, businesses and stakeholders that all people can use. The high streets for all approach is a popular approach in urban studies in recent years. Nevertheless, so far, it has not been mentioned in the research field of Persian texts and sources in the specialized field of urban planning. Although this approach is successful in global experiences. The purpose of this research is to look at the function of the street by presenting a conceptual model of the high streets. In addition, to validate and better introduce this new approach, two critical streets of Tabriz City (Imam Khomeini Street and Foroughi Street) have been compared from the perspective of this approach. The general approach of this research is descriptive-analytical. Collecting information and field data through a questionnaire and the sample size based on Cochran's formula is 384 people. The research findings show that the essential components of the "High Street for All" approach are more vital in Imam Khomeini Street than in Foroughi Street, and only Foroughi Street has a higher priority in the two indicators of "personal branding, presence of famous commercial brands." To create a High Street for all streets, it should be a strength at the comprehensive level of spaces in all dimensions, including the relationship between humans and the environment.Extended AbstractIntroduction:The High Streets for All mission seeks to stitch the actual uses of the city back together following decades of dispersal and separation and invites us to rethink how we live and move around the city. High streets are the places most people can walk to or get the bus from; they provide common access points to the city’s cycle routes, bus and overground systems. High streets are essential places of employment. This research seeks to know whether the idea of High streets for all is applicable in the cities and streets of Iran and the world. So far, many cities worldwide, such as London, the founder of this concept, have succeeded in implementing it, and these streets have become public places for everyone. In the current research, the theoretical foundations are aimed at the functional revitalization of urban streets. For this purpose, the sources are based on creating a conceptual model according to the contextual-cultural conditions of the case examples. Then, an evaluation was done on Foroughi Street and Imam Khomeini Street in Tabriz, both of which are commercial and essential streets of the city. This comparison aims to find the best high street for basics close to the High Street for everyone.Methodology:The statistical population in this research includes the entire city of Tabriz (according to the definition of urban scale for High Streets) and the sampling is from different people of the city according to the context of the subject. The size of the statistical population of Cochran's formula according to the population of Tabriz city (1,727,476 people) and taking into account the error level of 5% is equal to 384 people. After collecting the field data, Spss software was used to analyze each component in case samples to analyze the mean using descriptive statistics methods. Considering the normality of the data in both samples, the standard deviation was used T-test for two independent models (independent two-sample t-test). Also, collecting information through document study and using the latest sources in the relevant field.Results and discussion:Based on the studies and tests conducted, most of the average data indicate the high potential and parameters of the "High Street for All" approach in Imam Khomeini Street. About 14 leading indicators had a high statistical average in this sample. Still, in contrast to Foroghi Street, due to the presence of a new context in the component of economic sustainability (personal branding, presence of commercial brands), it has a very high average, which indicates the strength of the element (sustainability Economic) on this street. In general, it can be said that the hypothesis of the research is confirmed according to the investigations carried out, and Imam Khomeini Street is considered a well-equipped street with a high average in most of the indicators and from this point of view, it has a lot of potential for the growth and design of businesses.Conclusion:High streets are social; they promote mutual friendship and cultural exchange. At once, global and local high streets offer everyday experiences and opportunities for social interaction worldwide. Designers tell us they particularly value this opportunity to be around other people. This opportunity is significant to socially vulnerable groups like older people or new neighbors looking to make friends. The streets of the "High street for all" are one of the modern city's most characteristic features and the city's most familiar public property. Well-equipped streets are places where most of the city's people from every class and income group can walk. Shared access points to bike and bus routes indicate high access to these streets. Paying attention to the economic dimensions of sustainable cities, including supporting creative businesses through cooperative work centers and holding start-ups, is also one of the new topics of this approach. According to the investigations and the successful experiences of the world, this example of streets can be very successful in promoting and improving presence in urban spaces. Based on this, this approach can act as a strong driver in the direction of balance and creating inclusive spaces in the streets of Iran. This research tried to introduce this functionally successful approach with sample evaluation. We hope that sufficient attention will be paid to it in future research. Manuscript profile -

Despite its significance for candidates, there appears to be insufficient emphasis on investigating the washback, particularly the impact of MSRT on the English language learning skills of Iranian candidates. Thus, the current research aimed to investigate the modifications that Iranian doctoral students regarded as more advantageous in utilizing the MSRT module for the purpose of English education. With this objective in mind, a survey based on the MSRT washback was administered to a group of 150 PhD students selected from Islamic Azad universities located in Shiraz and Marvdasht, who varied in terms of their gender, age, and field of study. A mixture of stratified and convenience sampling methods was employed to choose the study participants. In the second stage of the research, a purposive sampling approach was used to select 30 PhD candidates from the same population to participate in the semi-structured interviews. The findings from the data analysis revealed both favorable and unfavorable consequences of MSRT washback. In addition, it was observed that MSRT preparation did not adequately equip the students with English listening and speaking skills, which are crucial for their academic English needs, in contrast to their reading and writing capabilities.

According to modern portfolio theory, diversification should cover the risk. This theory is based on the normality of assets return. Experimental findings indicate that the assets return non-normality. Higher moments are sed to upgrade traditional models with the primary presumption of a normal distribution in recent years. This study uses a higher moment and the entropy for diversification and selects a portfolio given a non-normality assumption. It is essential to use up-to-date information to increase the model's efficiency, and accordingly, we used the rolling window for new price information. For the financial information method, we use the total index return in the last five working days and weigh the shares of the banking, insurance, and leasing industries on the next working day and evaluate this for three years. Python, math, and NumPy libraries were used to analyze the data. The results show that a much higher moment model can provide better portfolio selection results in most cases. Manuscript profile -

The characterization of this natural mineral was determined using the XRD, XRF, SEM and FT-IR analysis. The MG adsorption onto high porous activated waste was studied based on the parameters of pH, temperature, adsorbent dosage, initial dye concentration and contact time. The equilibrium and kinetic adsorption models were experimentally investigated. The obtained data have suggested that the process of MG removal followed up the Sips isotherm and pseudo-second order kinetic. The thermodynamic parameters values consist of ΔG˚, ΔH˚ and ΔS˚ confirms that the adsorption of MG is spontaneous and exothermic reaction. In the optimal condition the removal of MG was more than 93%. This method has a number of advantages, including being low-cost and non-toxic and the availability of natural adsorbent.

On the other hand both fields of amatory and mystic poetry were endowed with beauty, and since women were assumed as the embodiment of beauty, therefore their image as beloved has been institutionalized. This could somehow justify Sanaii’s attitude towards the role of women in poetry. It should also be added that in Sanaii’s poems, women were not given their proper status. Although he might be offensive towards women, but it does not necessarily mean that women were regarded evil; while eulogistically writing in praise of women did not necessarily mean that they were reputed good either. An attempt was made in this article to trace the aforementioned elements in Sanaii’s Hadighat-ul-Haghighah and bring out their importance. Manuscript profile -

Since in the Islamic text the woman is to take heed as mother and wife so in this study we investigate the mother’s role in disposition of high risk adolescents’ behaviors. Having basic skills by the parents could decrease the stress inside their family and lead to reasonable and normative confrontation with children’s problems, specially the adolescents. The young people are too vulnerable to be at risk and great dangers may impend over their present and future health more than others. Parents’ emotional neglect, particularly the mothers’ can cause that the adolescents consider any least lapse or omission of the parents as unkindness toward themselves. Therefore they may suffer from lack of sense and self confidence. These conditions make them to withdraw from any rationality and find refuge in their fancy. Such a feeling leads to anxious insecurity and finlly to high risk behaviors by the adolescents. Manuscript profile -

HIIT1 group performed four sets of 30 seconds of running with an intensity of 19-20 RPE, two minutes of rest between sets in each session. HIIT2 group performed four sets of 60 seconds of running with the same intensity and four minutes of rest between sets. training was performed three sessions a week for four weeks. Blood samples were evaluated to measure serum levels of IL-6, TNF-α and hs-CRP 48 hours before and 48 hours after training. To analyze the data . Mixed analysis of variance (ANOVA) test was used at a significant level (P<0.05). hs-CRP level significantly increased only in the HIIT2 group (p<0.05). No significant difference was observed between the groups (p=0.377). The IL-6 significantly decreased only in the HIIT2 group (p<0.05). A significant difference was observed only between the HIIT2 group and the control group (p=0.031). The mean of TNF-α showed a significant decrease only in the HIIT2 group (p<0.05). a significant difference was observed between the HIIT2 group and the control group (p=0.042). It seems that medium-term HIIT training reduces inflammatory indicators (IL-6, TNF-α) compared to short-term and probably has a role in reducing the incidence of heart and metabolic diseases in these people.

It was observed that 24 and 48 hours after dexamethasone consumption, thymocytes decrease by 55 and 84%, respectively, which can be associated with a decrease in the ability of the thymus to mature and differentiate T lymphocytes. The aim of the present study was to investigate the effect of 4 weeks of high intensity interval training on IL-4 and IFN-γ gene expression in the thymus tissue of rats with dexamethasone-induced immune system weakness.Materials and methods: The research samples in the present study consisted of 24 male Wistar rats, which were randomly divided into 3 groups: healthy control group, immunocompromised control group, immunocompromised group + intense periodic activity. Weakening of the immune system of the samples was done by injecting dexamethasone for three days, and high intensity interval training was done for 5 sessions per week, at 85% of the VO2max speed of the samples, for 4 weeks. The data were analyzed using one-way analysis of variance and Tukey's post hoc test at the level of α ≥0.05.Findings: The data showed that the expression of IFN-γ and IL4 gene decreased with dexamethasone injection compared to the control group (p=0.0001), also performing intense intermittent exercise led to a further decrease in IFN-γ and IL4 gene expression in the thymus tissue, but This reduction was not significant (p=0.151).Conclusion: In the present study, it was found that dexamethasone reduces the function of the thymus in the production of inflammatory and anti-inflammatory cytokines, thereby reducing their function in the maturation of lymphocytes.

In this study, static analysis of a rectangular plate with the special case of high order correction of shear deformation was investigated by considering the, secant function in spatial change field. In this study, the relation between the changes and the Hamilton's principle has been achieved by forming the different energy term of the system. To solving the governing equations, the Navier - stokes equations are implemented using sinusoidal and sinusoidal functions and considering the boundary conditions of the system. By solving the equations, the deflection values of the plates are calculated according to the changes in the system parameters and the obtained results are compared with the results contained in the validated literature and the accuracy of them is sufficient. In conclusion, the bounded analysis with the help of secant functions is very close to the responses obtained from similar researches and in certain cases we can use these functions.

The creation of very small grooves with sub-wavelength sizes (nanometers) on a thin metal film leads to a significant increase in the sensitivity associated with molecular absorption. By concentrating light within the grooves, the peak wavelength shift is improved. When the groove is engraved inside the structure, the sensitivity improves to 8.4 times more than the grooveless structure. The sensor functions for plasmonic structures with symmetric and asymmetric grooves have been investigated and it is shown that the proposed sensor is capable of performing biomolecular detection in multiplex form.

Since information technology can’t any more be regarded as an advantage, the importance of human resources as a potential capital capable of facing with national and international problems, seems to be vital? For encouraging innovations, initial steps toward freedom of thought and the so-called "software movement" has been started. But what is necessary is a continuing and progressive movement. Paying special attention to this issue thus needs appropriate educational policy in higher education. Unfortunately, our present economical situation, the phenomenon of educational impurities in universities, and the problem of "brain drain", are not good symptoms when evaluating the status of science .Scientific and academic norms in society are potentially vulnerable at present time and universities, more than anything, look like agencies just for producing academic degrees. Because of vulnerability of status and value of science, the higher education system in our country has been damaged. Moreover, without motivated students for learning, adequate output for satisfying development demands is not achievable. Higher education is in crisis. This article tries to show the limitations and problems in front of development plans in higher education and suggests operational solutions for improving the spirit if innovation and entrepreneur through Attitude Reengineering in universities Manuscript profile -

For analogueaccelerographs (SMA-1), human and instrumental errors and in the case of digital ones (SSA-2), lowand high frequency noises would be included in accelerograms. In order to use the accelerographrecorded data in practical applications both, errors and noises, should be omitted. The main purpose ofthis paper is to find different types of errors and noises which appear in the accelerograms and then tointroduce appropriate methods to remove them as to maintain characteristics of the recordedearthquake. Correction methods are based on mean removal, base line correction, and high and lowfrequency removal by the use of low-pass and high-pass filters. Acceleration, velocity anddisplacement time history were used in processing earthquake signals in the time domain andfrequency content of earthquake was shown using frequency spectrum in frequency domain. All of theabove-mentioned corrections and processings were also applied to a raw accelerogram. The studyindicates that correction of accelerograms before application is inevitable. Besides, selection of cut-offfrequencies in order not to lose earthquake frequency content is not the same for various records andthe filtration process would be better done using the frequency amplitude spectrum related to theparticular accelerogram.

Norm-evading is among the considerable approaches of transforming language as literary material into a poem that is in the mind of the creative group as long as don’t damage the original expression. Leach, the English linguist, considers norm-evading as the tool of poem creativity. The present article tries to investigate and analyze norm-evading in Yadullah Royaii’s poems based on Leach’s eight patterns (the syntactic, periodic, conceptual, wordily, styling, writing, dialectical, and vocal norm-evading) and with an analytic-descriptive method pays to the norm-evading components of Yadullah Royaii’s poems, the volume-oriented poet. The results show Yadullah Royaii, the contemporary poet and reviewer, has used some methods and tricks in this way which include: Balancing (poem melody): any extra-normative type: the conceptual extra-normative and defamiliarization. The predominant aspect in every collection of Royaii’s poems is different compared with other poem collections, and Royaii has benefited more from a part of those tricks depending on the time of composing the poem and the evolution of his linguistic experiences in each one of his poetic collection.

The present study aims to investigate the various areas of Global Citizenship Education (GCE) in the academic general curriculum in Iran. This is an applied research wherein, a qualitative content analysis method, the thematic analysis (themes), has been applied to the two levels of the selected documents (the law on the goals, duties, and organizations of the Ministry of Science, the comprehensive scientific map of Iran, and Iran''s sixth development plan) and syllabuses of the general courses approved by the Supreme Council of the Cultural Revolution. The data collection tools included content analysis, note-taking, and a checklist. A descriptive-analytic method was applied to interpret and analyze the data. Based on the research findings, the level of contents associated with globalization has a significant degree of severity and weakness from one course to another in terms of the qualitative aspect. It is certain that most of the contents related to the components of globalization often have indirect links and regarding the positive, negative, and neutral aspects, it can be claimed that the neutral aspect is of considerable significance compared to the other aspects. The qualitative content analysis of the documents and syllabuses of the general courses was done and subsequently, the obtained scheme indicates that the existing approach to the GCE in Iran is a combination of political and civic education approaches, cultural transfer, and the neo-liberal approach, and hence, the educational system should try to train global citizens with Iranian–Islamic identity. Among the important points in the analysis of the documents is a lack of distinction between globalization and internationalization. Manuscript profile -

Military targets detection can provide commanders with a variety of information on the status of activities, deployment of forces, military arrangement of targets, and many other information from a military area. In recent years, the advancement of remote sensing technology has made it possible to produce different images with high resolution Spectral and spatial. fusion of hyperspectral and high resolution imagery can help effectively identify, extract, and produce maps from the constituent elements of an environment. The purpose of this research is to target detection (military) using fusion of hyperspectral and high resolution imagery. For this reason the Hyperion, ALI and OrbView3 data was acquired. Firstly, Hyperion Data Preprocessing was used in terms of unused bands, bad straights, atmospheric correction and geometric correction. The image of Hyperion in a two-step process with panchromatic bands combined ALI and OrbView3 images using gram-schmidt, Pc Spectral, and IHS algorithms. The combined results showed that Gram schmidt had the best spectral and spatial performance. In the next research, the MNF conversion was used to reduce the image size and reduce the noise, and the PPI algorithm of the purest pixels was used to extract the spectral profile in a visual and precise manner compared with the reference spectra. In the following, algorithms, BANDMAX, spectral angle mapper and divergence spectral information were used to identify the targets. The results of the identification of the objectives showed that the BANDMAX method with a Overall accuracy of 89.25 and Kappa coefficient of 0.723 was better than the other two algorithms.

Methods: The statistical sample of this study was 20 footballers with a mean age of 18.9 ± 0.5 years, weight 1.7 ± 1.7 kg, height 176 cm2.2, body mass index of 22.4 ± 1 kg / m2 and the maximum consumed oxygen was 51.3 ± 2.5 ml / kg body weight, which was randomly selected among the soccer players of Esteghlal'e Novin team in south of Tehran. Subjects were participated in two groups with two tests, active recovery and inactive recovery. Blood samples were collected from both groups before and immediately after recovery then, cortisol, and IL-6 and CRP levels were evaluated using ELISA technique. Results: There was no significant difference between active and inactive recovery after HIIT activity on CRP and IL6 responses. While there was a significant difference between active and inactive recovery after HIIT activity on cortisol response (P <0.05). Conclusion: The results of this study showed that active recovery after HIIT activity could affect cortisol response. Therefore, active recovery would be more effective than passive recovery.

The purpose of this study was to investigate the effect of four weeks of high intensity interval training (HIIT) versus four weeks of aerobic training on serum levels of ceruloplasmin and malondialdehyde in elite handball player girls.Methods: Thirty young handball player girls (mean aged 16.85±1.4 years), with four years of membership in handball team of North Khorasan province, were selected and randomly divided into two groups of training and one control group. Subjects in experimental groups participated in four weeks of HIIT [running at intensity of 95-90 percentage of maximum heart rate and resting intervals of 1-3 minutes running at 60-50 percentage of maximum heart rate] and aerobic training (running at 50-70 percentage of maximum heart rate, 45-60 minutes per session), three sessions per week. The blood samples were taken factors before and 48 hours after last training session to assess blood factors. Data analysis was done by One-way ANOVA, paired t-test, and Pearson correlation, and P<0.05 considered significant.Results: Serum levels of MDA decreased significantly following aerobic training (P=0.044). Moreover, weight (P=0.009), body mass index (BMI) (P=0.002) and body fat percent (P=0.036) decreased significantly following HIIT. Furthermore, aerobic training resulted in significant decline in weight (P=0.008), BMI (P=0.015) and body fat percent (P=0.013).Conclusion: It seems that the volume of training influences on serum levels of MDA; however, ceruloplasmin levels was affected by neither intensity nor volume of training.

Therefore, the Purpose of this study was to investigate the effect of six weeks of high intensity interval training (HIIT) on adipose tissue levels of MiR-193b and insulin resistance index in male diabetic rats with high fat diet and streptozotocin. Twenty male wistar rat (10-12 weeks old, 370/25±13/76 gr) selected and following the induction of type 2 diabetes, the diabetic rats were randomly divided into experimental and control groups. The rats in the experimental group participated in six weeks of high intensity interval training of running on a treadmill with 40 seconds of repetitions with 2 seconds of active rest between each repetition, 30 minutes per session and five sessions per week. All rats were dissected 48 hours after the last training session and the blood indices were evaluated using appropriate laboratory methods. Data analysis were done using independent and paired t-test and Pearson's correlation test at a significance level of less than 0.05. Results: Adipose tissue levels of MiR-193b following six weeks of HIIT in experimental group were higher than control group; whereas, levels of insulin and fasting blood glucose , insulin resistance index and body weight were in the experimental group compared to the control group. Furthermore, Six weeks of high intensity interval training in experimental group caused in significant decreases in body weight in post- test compared to pre- test . Moreover, according to the Pearson correlation test, there were negative significant correlations between the changes in levels of adipose tissue levels of MiR-193b following HIIT and changes in body weight (P=0.038). Six weeks of HIIT play role in improving insulin resistance by increasing the MiR-193b levels in addition to improve body composition. Manuscript profile -

The present study was qualitative phenomenological research and conducted in terms of applied purposes. The statistical population consisted of 154 teachers and 620 students. Of these, the target population was selected through purposeful sampling. 15 teachers and 17 students were selected respectively. Semi-structured interviews and open-ended questionnaires were used to collect data. Data analysis was done by cluster analysis method. Data was analyzed using continuous comparative method. According to the findings of the research, the most important factors in students' low attention of high school textbooks based on viewpoint of teachers and students themselves can be divided into two general categories of personal or personal factors and school or environmental factors. From the perspective of students, the most important personal factors were lack of motivation due to observing unsuccessful people, unreasonable ambiguity in the future of employment and resorting to external documents and school factors were lack of facilities, teacher misconduct, curriculum content weakness, and long duration Educational hours. But in a more or less identical look, teachers find the most important personal factors as: lack of motivation for progress, identity confusion, false self esteem, mental concentration problems, mobile addiction, family problems and drowsiness, and school factors including long hours of instruction, poor physical standards of classes, poor content of the textbooks and poor ability in note-taking.

The data was analyzed by SPSS version 25 and SmartPLS version 3.2.8. The results showed that validity and adequacy of the suggested model was suitable. Thus, it could be used in different situations by experts in the related areas. The relationship between positive perceived behavioral control and academic achievement was significant; perceived behavioral moderated the effect of negative emotion and stress on academic achievement. The key role of professor skills in academic achievement of students was confirmed directly or through its effect on positive emotion. The effect of teaching skills was not significant on academic achievement of students with negative perceived behavioral control, while the effect of academic stress was confirmed on these students. Therefore, identification of students with negative perceived behavioral control and psychological interventions for these students can be effective in their academic achievement and their mental health.

The aim of current research was to investigate the relationship between basic psychological needs (autonomy, competence and relatedness), learning strategies (deep and surface) and students' academic achievement in a form of casual model. 285 high school students in Salmas city were selected using stratified sampling method and answered to learning strategies and basic psychological needs questionnaires. Path analysis was use for data analysis. The findings revealed that tested model had sufficient fit and predicted 23% of changes of academic achievement, 14% deep learning strategies and 13% of variance of surface learning strategies. Deep learning strategies had positive and significant effect on academic achievement. But the effect of surface learning strategies on academic achievement was negative and significant. Need for autonomy and competence had positive and significant effect on Deep learning strategies. But the effect of need for relatedness on this variable wasn't significant. Also, the effect of need for relatedness on surface learning strategies was positive and significant.

The data of the first questionnaire related to the components of higher education were used by Demetel technique (Atlas software) and for the second questionnaire related to teaching patterns, fuzzy TOPSIS method was used. Components of socio-cultural commitments, professors and political factors ranked first to third in terms of effectiveness of evaluation components, staff and the type and structure of the organization ranked first to third in terms of effectiveness. Also, individual teaching models were considered the best model for successful teaching and traditional teaching models were considered the worst model. The results show that teachers in universities should try to learn and improve the level of other models while strengthening traditional teaching patterns. Managers and policy makers should seek to improve the culture of universities by using modern teaching models. Manuscript profile -

The effect if each component of curriculum (purpose, content, duration, and evaluation) on vocational empowerment component (general and social skills, self-management, self-sufficiency, economic sufficiency, and vocational empowerment) was studied. The statistical population included all administrative officials, curriculum designers, teachers, and employers in Qazvin. A sample (223) was selected through randomization. The data gathering instruments were two researchers-made questionnaires based on 1-10 Likert scale. The results showed that administrative officials and curriculum designers regarded the curriculum effective in increasing general and social skills, self-management, self-sufficiency, economic sufficiency, and vocational empowerment. However, according to teachers, and employers the curriculum has little effect on promoting the skills. It can be argued that teachers and employers as implementers of the curriculum are more reliable source to evaluate the program. As a result, administrative officials, curriculum designers are recommended to revise the existing programs Manuscript profile -

One of the effective factors in export success is the valid national brand of the country of origin with the customers of the destination country. One of the industries with local capabilities and strong infrastructure in Iran is the electricity industry. Despite the quality and self-sufficiency in the products of this industry, the lack of a pattern in using the national brand in this industry has become an obstacle to reach regional markets. Accordingly, the main purpose of this study is to "present an effective model on promoting the image of the national brand of Iran."In this mixed research, which has been done sequentially. Researchers tried to identify the factors affecting the promotion of the national brand image (made in Iran) and its dimensions using the opinions of experts. Then, with the help of Maxqda software, the variables and the conceptual pattern of the relationships between them were extracted. In a small part, using the opinions of executives and exporters of high voltage power products, the local status of the research model was examined. The results of PLS software analysis in the structural equation model section showed that among these relationships, the variable "utilization of human, cultural, social and historical manpower capacities" has the greatest impact on strengthening the national brand and the variable "national macro policy" has the least impact.

Fluctuation plays a key role in option pricing, portfolio management and the market sentiment. In general, financial institutions are faced with four various kinds of risk, which are credit risk, liquidity risk, operational risk, and market risk. The most appropriate method to measure the market risk is by using the VaR (value at risk). Value at Risk is statistical technique used to measure and quantify the level of financial risk within the investment portfolio over a specific time frame. It is always expressed by the monetary amount that is at risk as well as the probability of loss. This research is to predict the VaR for a one-day period in six different industries in which three companies are monitored in each industry. The time periods of the study are 30-minute intervals between 91/11/1 to 92/4/1, in which the GARCH model is used for predicting the variance. The research then checks to see whether the data fits the normal or t-distributions models. Thus, six models are used for six different industries. All six chosen models are deemed proper to predict the coefficients, how fit the coefficients are, and Watson statistic camera. The estimation of the variance and the Var for all models is done at a %95 confidence interval. The research concludes that the companies involved in the basic metals group are more prone to risk and have higher VaR in comparison to other industries. Manuscript profile -

The widespread impact of these buildings on the body and space of today's cities is undeniable, as it has caused high-rise buildings to be reviewed by experts in various fields. High-rise buildings in today's cities have always been one of the most influential aspects of urban landscapes, and the symbolic, aesthetic, identity, and readability aspects of the environment are among the dimensions to be considered in their role in the urban landscape. In recent decades, the vertical growth of cities has been increasingly studied and buildings act as a single complex that serves and receives. High-rise construction has been used to exploit downtown lands and to produce and pay attention to urban economy. While most decisions in our country for this type of building are made without regard to this. Construction of high-rise buildings, limited to authorized or special areas for high-rise construction in some sub-zones of land use in Tehran and subject to permission in terms of earthquake zoning studies and related rules and regulations and permitted environmental zones whose location and permitted uses: 2000 Detailed plan zoning is specified and refined. The development of cities in the present century to respond to problems such as population growth, public demand for life and work has increased attention to vertical expansion. A high-rise residential complex is a way to respond to the prevailing conditions. These residential complexes have advantages and disadvantages in their structure and many of them have formed their spatial structure based on the existing rules and regulations and the main structure of the spatial structure has been in them. To control the spatial structure, it is necessary to control all the forces in each building, which requires recognizing the elements and components of the spatial structure, which has not yet been explained and reviewed. As a result of this research, the criteria have been formed by examining and prioritizing the criteria according to the extent of their factor contribution in the formation of high-rise buildings. The research method is a combination of qualitative and quantitative nesting. In the qualitative stage, the interview was used to collect information and the questionnaire was used in the quantitative stage. The software used is in the quantitative part of JMP and in the qualitative part of ATLASTI. The results show that the most impact belongs to; Criteria for height restriction on the distance between the elements with the amount (1.000), criteria for spatial restriction on the components of the unit with the amount (1.000), criteria for fire extinguishing on the components of the unit with the amount (0.982), criteria of elevator on the texture with the amount ( 1.000), but the least effective include the criteria of height restriction with physical continuity (0.388), the criteria of spatial restriction with texture (0.514), the criteria of elevator on the physical connection with the amount (0.356) and the criteria of fire extinguishing Form with value (0.246), exit criteria with unit components with value (0.401), criteria of physical structure on readability with value (0.213), physical coherence and criteria of energy consumption and saving with physical coherence with value ( 0.388), the criteria for the placement of vehicles with physical differences with the value of (0.255) and the criteria of protrusion on the spatial zoning with the value of (0.262).In recent decades, the vertical growth of cities has been increasingly studied and buildings act as a single complex that serves and receives. High-rise construction has been used to exploit downtown lands and to produce and pay attention to the urban economy. Impress. Due to the lack of localization and mere emphasis on some aspects of the spatial structure, the rules have caused some parts to remain rigid and inattention to other parts in the design of the spatial structure. In various researches, the effect of different groups of criteria on the elements of spatial structure has not been discussed and analyzed. To control the spatial structure, it is necessary to control all the forces in each building, which requires recognizing the elements and components of the spatial structure, which has not yet been explained and reviewed.

The experiment was carried out in a split-factorial arrangement of treatments based on randomized complete block design with three replications. The main plots consisted of three levels of irrigations (irrigating after 60, 90 and 120 mm evaporation from class A evaporation pan). Two levels of nitrogen replacement with phosphorus and without replacement and two levels of phosphorus replacement and without phosphorus replacement assigned to subplots. The results showed that simultaneous replacing of nitrogen and phosphorus in all irrigation levels increased physiological growth indices of leaf area index, dry matter accumulation, crop growth rate, relative growth rate and net assimilation rate. Moisture stress reduced growth rate of the crop significantly. Results also showed that crop growth rate increased 35 to 45 days after planting and reached to its maximum level after 65 days after planting date. After this period, the crop growth rate of soybean decreased and reached to zero about 95-100 days after planting. The highest dry matter accumulation and crop growth rate were obtained from irrigation after 60 mm evaporation and nitrogen-phosphorus simultaneous placement application. According to the results, simultaneous replacing nitrogen and phosphorus, reduced the negative effect of moisture stress on soybean growth indices. Nitrogen replacement with phosphorus increased grain yield by 11.4% as compared to non-replacement of nitrogen with phosphorus and yielded 3855.88 kg.ha-1. In this research, nitrogen replacement with phosphorus under irrigation after 90 mm evaporation prevented significant oil yield loss as compared to irrigation after 60 mm evaporation.

Families are constantly striving to care for their children so that children are raised away from injury and do not engage in risky behaviors. High-risk behaviors are behaviors that are intentional and the person has little control over the possible side effects, such as smoking, alcohol, drugs, psychotropic drugs, and performing early sexual behaviors. The aim of this study was to analysis family-based care and prevention strategies for high-risk behaviors. This study has a hermenutic and constructive-interpretive paradigm and in terms of basis, qualitative research and data collection technique, in-depth and semi-structured interviews. To analyze the data, grounded theory method, with open, axial and selective coding process has been used in order achieve the final theory. The universe included families from Tabriz and sampling was done through purposeful sampling and with the participation of 26 families, theoretical saturation was achieved. Findings show that families follow the following triple model to take care of appearing high-risk behaviors: 1. Inefficient care strategy (lacking effective strategy); 2. Impulsive care strategy; 3.

For this reason, the culture media was inoculated with a standard strain of histamine-producing Staphylococcus epidermidis TYH1, as well as S. capitis and S. carnosus strains harboring histidine decarboxylase-hdc. The migration time of histamine in CZE assay and retention time of HPLC were found 5.4 and 12 min, respectively. The calibration graph was linear ranged 6.25 to 200 μg/ml which was estimated using the regression equation of y=0.000004x (r2=0.999) for both methods. Determination of histamine produced by these three strains indicated no significant differences using CZE with HPLC methods. The results show that the CZE is suitable for the determination of histamine in bacterial culture, since, there is no need for initial preparation, simplicity, sensitivity and low cost.

Some of these substances not only remain on the surface of crops but also penetrate their tissues, as most of the crops exposed to pesticides contain amounts of pesticide residues that enter the consumer's body along with foods. For this reason, the use of precise and efficient methods in evaluating the residuals amounts of these compounds in food products is of great value. In this research, a combination of air-assisted liquid-liquid microextraction and liquid-liquid microextraction with solidification of floating organic drop methods has developed for extraction and preconcentration of some of the widely used organophosphorus pesticides used in Iran (Diazinon, Chlorpyrifos, Phosalone, Parathion- methyl and Azinphos-methyl) from juice samples before their analysis by high-performance liquid chromatography. Under optimal conditions, 32 μl of menthol as the extraction solvent and 75 μl acetonitrile as dispersive solvent at a temperature of 60 °C used to extract the analytes. The proposed method is simple, reliable, and inexpensive and yields optimal values for extraction efficiency so that under optimized conditions the recoveries ranging from 61 to 79%. RSD% was in range 4.6 to 6.9, indicating high reproducibility of the proposed method. Other advantages of this method include low organic solvents consumption and short analysis time.

This study aimed to investigate the content of histamine and tyramine in cheeses distributed in Qazvin. Sixty samples including 30 samples of Koozeh cheese, 15 samples of pasteurized cheese, and 15 samples of probiotic cheese were collected randomly from September to December 2021 from Qazvin. The content rates of histamine and tyramine in the samples were determined by high-performance liquid chromatography. All cheese samples contained histamine and the samples of Koozeh, pasteurized and probiotic cheeses contained 100%, 100% and 6.66% of histamine, respectively which are higher than the permissible limit (100 mg/kg). The mean value of histamine in the samples of Koozeh, pasteurized and probiotic cheeses were 208.37±34.94, 123.80 ± 12.04, and 66.67 ± 18.27 mg/kg, respectively (p<0.05). The values of tyramine in all the samples were within the permissible limit (600 mg/kg) and the mean values of tyramine in the samples of Koozeh, pasteurized and probiotic cheeses were 145.85 ± 15.24, 77.49 ± 10.34, and 45.98 ± 9.31 mg/kg, respectively(p<0.05). According to the results, it seems that the use of Koozeh and pasteurized cheeses in Qazvin is not suitable for people who are sensitive to high levels of histamine, and it is recommended that this group of people use probiotic cheese.

The aim of the present study was to determine the residual levels of tylosin, gentamicin, and neomycin in milk and ice cream distributed across Tehran. A total of 125 samples, including raw milk, pasteurized and sterilized milk, traditional and pasteurized ice cream. The samples were randomly obtained from retail centers in Tehran from July to September 2019. The residual levels of tylosin, gentamicin, and neomycin were determined using high-performance liquid chromatography (HPLC) method. Of the samples, tylosin, gentamicin, and neomycin were detected in 94.4%, 92.2%, and 96.6%, respectively. The highest tylosin residues in raw milk and ice cream samples was 26.72 ± 1.55 and 26.01 ± 1.55 μg/l, respectively. The highest gentamicin residues in raw milk and ice cream samples were 28.15 ± 1.29 and 28.8 ± 1.29 μg/l, respectively. The highest neomycin residues in raw milk and traditional ice cream samples were 33.46 ± 1.95 and 34.7 ±1.95 μg/l, respectively. According to the Iranian National Standard, in all tested samples the residual antibiotics were below the standard approval limit. Since most samples contained antibiotic residues, continuous monitoring of milk samples for antibiotic residues is recommended. Manuscript profile -

The most popular and sensitive method for determining low amounts of pesticide residues in order to find out their maximum residue levels (MRLs) in food products is the chromatographic assay. In the present study, the diazinon, chlorpyrifos, imidacloprid, acetamiprid, thiacloprid and fenvalerate insecticides were extracted from cucumber samples by using QuEChERS method in combination with liquid-liquid microextraction and were determined by HPLC-DAD. For this purpose, the effective factors in the developed extraction method were optimized and the mentioned method was validated. Based on the results, the target analytes were successfully extracted simultaneously using 2 ml of a mixture of acetonitrile, methanol, and acetone (in the QuEChERS step). Further, the highest efficiency in the second extraction step was obtained using 65 µl of hexanol and 15% NaCl. The LOD between 0.36 and 0.57 ng/g, high repeatability in the range of 3.6 to 6.8 (based on the RSD%), and extraction recovery of analytes in the range of 76 to 84% of the developed method's merit figures indicate the method's high capability in extracting particular pesticides. Overall, the procedure described in this study is a simple and cheap method and has a good ability to extract the desired pesticides from cucumber samples. Manuscript profile -

Regular exercise has been shown to modulate oxidative stress, reduce brain damage, enhance hippocampal neurogenesis, and improve spatial memory. Acetyl-L-carnitine, known for its protective and antioxidant properties, can enhance brain function. This study aimed to investigate the combined effects of High-Intensity Interval Training (HIIT) and acetyl-L-carnitine supplementation on substantia nigra tissue in a rat model of Parkinson's disease induced by 6-hydroxydopamine. A total of 36 male rats, weighing 270±20 g, were randomly divided into six equal groups: control healthy, surgical sham, Parkinsonian (unilateral single injection of 6-hydroxydopamine in the substantia nigra at 12.5 µg/ml), HIIT (8 weeks, 5 sessions per week), acetyl-L-carnitine (100 mg/kg daily for 8 weeks by gavage), and concurrent acetyl-L-carnitine + HIIT (similar regimen as groups 4 and 5). Spatial memory was evaluated using the Morris water maze test, and after euthanasia, brain tissue was collected to assess pathological changes in the hippocampus. Data were analyzed using ANOVA and Tukey post-hoc tests with a significance level of p<0.05, employing SPSS 23 software.Parkinson's disease induction resulted in reduced spatial memory indices. HIIT and acetyl-L-carnitine supplementation significantly improved spatial memory factors (p<0.05). Statistically, the combined HIIT and acetyl-L-carnitine treatment demonstrated the most substantial improvement in spatial memory indices. This study suggests that concurrent HIIT and acetyl-L-carnitine treatment can enhance spatial memory and ameliorate pathological changes in the hippocampus of Parkinson's disease rats.

Probiotics are food supplements containing live microbes which balance the flora of the digestive system and produce positive effects in the host body. L.acidophilus is a beneficial bacterium used in the production of probiotic products .The aim of this study is to evaluate the effects of consumption of milk containing L.acidophilus on serum lipid trends of rats fed high lipid diet. This is an experimental study in which 30 male albino Wistar rats with a body weight of 200±15 gr. were randomly allocated to two groups of treatment and control each containing 15 rats which were adapted to a high lipid diet (11.74%) and water containing 25% milk within a week. Rats in both groups received high lipid diet and water containing 25% milk for 60 days with the exception that rats in the treatment group received water containing L. acidophilus at a level of 109 CFU/rat/day throughout the experiment. Independent t-test revealed that at a level of α= 0.05, mean levels of total cholesterol and LDL-C of rats in the treatment group was significantly lower than the control group (p<0.05), and HDL-C of rats in the treatment group was significantly higher than the control group (p<0.05), but the mean levels of triglyceride and VLDL-C was not significantly different. Also increase in body weight was significantly higher in the treatment group compared with the control group (p<0.01). On the whole, long term daily consumption of milk containing L. acidophilus improves serum lipid trends by lowering total cholesterol level and LDL-C and increasing HDL-C and also increases the rate of body growth.

The aim of the present study was to evaluate the protective effects of Crocin on rat high fat diet-induced hepatic steatosis model. For this purpose male Wistar rats were given either control diet, high fat diet alone or high fat diet plus Crocin via gavage at different doses (25, 50 and 100 mg/kg) for 4 weeks in different experimental groups. Histopathological studies of the liver were conducted in all experimental rats at the end of experiment. Animals of the different groups were sacricified by cervical dislocation. Liver issue specimens were fixed in 10% buffered formalin and 5 micron thick sections were prepared using routine hitopathological techniques.The serum levels of aminotransferases, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured to determine hepatocyte injury. Alkaline phosphatase (ALP) and total bilirubin (TB) were measured to assess biliary function. Albumin (Alb) and total protein (TP) was measured to reflect liver synthetic function. Histopathology of the liver in high fat diet fed rats showed severe fatty change of hepatocytes. Crocin reduced accumulation of lipid droplets in the hepatocytes in a dose dependent manner. In the high fat diet fed rats, serum levels of ALT, AST, ALP and TB significantly (p<0.01) increased, and serum Alb as well as TP levels significantly (p<0.01) reduced in comparison with normal control rats. Crocin treatments (100 and 50 mg/kg) significantly (p<0.01 and p<0.05, respectively) reduced elevated markers of liver tissue injury and significantly (p<0.01 and p<0.05, respectively) increased serum Alb and TP levels in high fat diet fed rats. Low dose of Crocin (25 mg/kg) made no significant changes in the mentioned parameters. The results obtained showed that Crocin has protective effects against hepatic steatosis in rats fed with high fat. Manuscript profile -

One of the important challenges of this model is the diminishing of the decision-making unit’s precision when dealing with a multitude of inputs and outputs. Hence, the aim of the present research was to develop a comprehensive performance evaluation model while enhancing the resolution of decision-making units. To this end, a balanced scorecard was used to identify comprehensive indicators. At the same time, for the first time, two objective and subjective approaches based on factor analysis and fuzzy inference system were used simultaneously to reduce indicators and improve the resolution of decision-making units. This study used an explanatory-descriptive method and was conducted as an applied-developmental research. The statistical population for identifying performance evaluation indicators and developing fuzzy inference rules included the experts of higher education institutions of Semnan city. Moreover, twenty-four higher education institutions of Semnan city were selected for model testing. The researcher made two questionnaires for the data collection. The validity of the questionnaires was confirmed by content and construct validity, respectively. Also, the reliability of the questionnaires was confirmed by Cronbach's alpha value and composite reliability of more than 0.7 respectively. The main accomplishment of the research can be designing a unified model with objective and subjective approaches to improve the resolution of decision units. In this regard, 26 indicators were identified and reduced to 8 structures by factor analysis. Also, the structures were scored by relying on the designed fuzzy inference system. The results demonstrated a significant improvement in the resolution of decision-making units when utilizing the proposed model, in contrast to conventional models which are mostly based on objective and subjective methods. As a result, the number of effective units in the proposed model effectively reduced to 10. Additionally, the results of the Kruskal-Wallis test and the calculation of the standard deviation of the efficiency scores revealed that the proposed model with an average rating of 48.29 and a dispersion of 0.221 has a lower efficiency rating and a greater dispersion as compered to other models. This finding serves as a confirmation of the enhanced resolution achieved by the proposed model Manuscript profile -

In addition to its positive effects, the tendency to build high-rise buildings in the big cities of Iran has had harmful effects and consequences in different dimensions, especially in the social dimension. In this regard, the aim of the current research is to investigate the effects and social consequences of the increase in high-rise construction in Tabriz metropolis. The research method in the current study is applied in terms of purpose and in terms of descriptive-analytical nature, in order to analyze the information were used partial least squares method in Warp-pls software and F test or analysis of variance. The statistical population of the research includes the citizens of the 1st, 2nd and 5th regions of Tabriz, that is, the residents of Aftab Towers in Valiasr (region 1), Asman Towers in El Goli (region 2) and Mehr Towers in Roshdieh town (region 5), which is in line with determining the sample size. Cochran's method was used and the sample size was determined to be 384 people. The findings of the research show that the most important social consequences of high-rise development in Tabriz metropolis are related to the components of disruption in social interactions, reduced sense of belonging to a place, disruption in socialization, reduction in mental health and disruption in privacy, which the coefficients obtained from the structural model are 0.651, 0.574, 0.433, 0.411 and 0.383 for each. Also, among the sub-components, the highest impact of high-rise development is related to the reduction of social connections with friends and neighbors, reduction of place identity and sense of place belonging, and lack of formation of participation and social trust between residents. The predictive power of the designed model is analyzed using the coefficient value for the dependent variables, values greater than or equal to 0.1 have been specified for the determination coefficient. Therefore, it was concluded that the structural model of the current research has sufficient power. In this model, 13.4% of the variance of the variables of social effects and consequences of high-ranking is justified by the variables entering it. Based on the Stone-Geyser test, because the values of the Geyser test are calculated to be higher than zero, it shows that the considered model has the necessary capacity and predictive power.Also, the comparative analysis of the studied towers based on the analysis of variance method shows that there is no significant difference between the social consequences caused by high-rise construction between these towers. Variance analysis test is used to measure the difference between the average of a variable in more than two groups (3 groups and more). According to the amount of F statistic with 22.321 and a significance level of less than 95%, the obtained results indicate that there is no significant difference between the selected indicators in the current research between the towers under study.

Lack of physical activity among students is a global problem: students spend most of their time in school, which significantly reduces the amount of daily physical activity as they sit in class for long periods of time. Physical education lessons and coaches alone cannot be enough to motivate students to exercise, sports equipment and facilities are also necessary to help motivate students. This requires an environment that is conducive to their interest. In the world, there is in average of 5.2 square meters of sports space per student, but in our country, it is only 0.17 square meters. Lack of students’s physical activity endangers the physical and mental health of the society and this makes researches necessary in order to find the factors and solutions that lead to the increase of sports and physical activity of students. So these were the questions: What spaces encourage physical activity and sports from the students, principals, and teachers point of view? What features should this space have to encourage physical and sports activities? The purpose of this research was to identify spatial factors that enhance sports and physical activity from the students, principals and teachers point of view, so that schools can be actively designed and the school environment supports the students' sports activities.This research was based theoretically on behaviorism which deals with the relationship between environment and behavior and focused on the case study of the second cycle all-boys high schools in Marivan. The method of this research was to quantitatively collect the views of students, principals and teachers through a researcher-made questionnaire. The statistical population of this research was the principals, assistants, and sports teachers in one group, and the students of less and more deprived schools in terms of space and sports fields in another group. The answers were analyzed using SPSS 26 software. The reliability of the questionnaire was evaluated with Cronbach's alpha coefficient. The KMO test was used to check the factor loading of the questions. A significant test (t) was conducted between the group of principals and vice-presidents of schools, with the group of school sports teachers and physical education experts, as well as among less and more benefited students in terms of school sports environment.The results showed that The first priority from the students' point of view is the hardness of most school sports fields (especially the asphalt type, due to the separation of asphalt particles from the ground during sports use), the presence of obstacles near the sports fields, the lack of sufficient and suitable space for the fields. Depending on the sports field and the number of students, they have fully felt the lack of security during sports activities and have experienced the injuries and problems that have occurred. According to Maslow's Pyramid Of Needs, the need for security is one of the most basic and important basic needs of every human being. So, students need a safe and risk-free environment to increase their interest. Manuscript profile -

Methods: For this purpose, 14 volunteer players of the Iranian women's national basketball team (with an average age of 23.0 ± 3.24 years, weight 63.6 ± 8.50 kg, and body mass index = 21.8 ± 3.15 kg/m2) were selected and randomly divided into two experimental (n=7) and control (n=7) groups. Before and after the exercises, the subjects performed 1 incremental test with breath gas analysis to determine some physiological variables and a Wingate test to determine maximum power (PPO) and average power (MPO). Both groups followed the same basketball training program for four weeks while the experimental group performed the anaerobic sprint protocol (RAST) as a HIT protocol twice a week along with the basketball training program.Results The results of the ANCOVA test showed that the experimental group had a significant increase in VO2max (p=0.001), vLT (p=0.011), VO2max (p=0.001) and maximum oxygen pulse (p=0.001). Implementation of HIT also caused a significant increase in maximum power (p = 0.03) and average power (p = 0.02). Conclusions: The present findings showed that the intense interval training program with short rest periods can increase aerobic and anaerobic performance in the short term. Manuscript profile -

In recent years, with the spread of obesity and metabolic complications caused by obesity, much scientific attention has been paid to the study of adipose tissue. Today, adipose tissue is not considered a static tissue that stores only energy, but is considered a metabolically active tissue. Like the glandular system, metabolic tissues secrete various secretory factors that have auto, para and endocrine functions depending on the extracellular environment. Environmental factors such as diet, physical activity, and metabolic status are the main causes of overweight and obesity; in turn overweight and obesity are also affected by genetic traits. As a general rule, excess body fat is the result of a long-term imbalance between energy intake and energy expenditure. Conclusion: Proper selection of exercises is an important factor in changing the lifestyle of obese children and adolescents and is an effective indicator in the control and treatment of obesity. Physical activity creates a negative energy balance due to increased energy consumption. Recent research suggests that high intensity interval training (HIIT) creates a temporary state of anorexia that delays hunger for a short time after exercise, but this effect is short-term. On the other hand, HIIT plays a role in the changing energy consumption through changes in hunger and appetite signals as well as regulatory peptides at the levels of short to long-term signals in obese individuals. This review article discusses the effectiveness of HIIT in obese people. Keywords: Obesity, High Intensity Interval Training, Hormone Extended Abstract Introduction Recent advances in obesity research have shown that genetic mutations do not justify the growing trend of obesity, and that environmental factors and lifestyles are more effective. Although some people may be prone to obesity and related diseases as a result of genetic factors, it is not the only cause of obesity, and there are other determinants of the condition (1). Today, the obesity index is expanding due to the change in modern lifestyle, which indicates an increase in calorie intake and a decrease in physical activity, and it is believed that the cause of obesity is really complex and vague and is not well known (5). Several peptides released by peripheral tissues interact with specific areas of the brain, and the secreting neurons release anti-appetite or appetizing neuropeptides that are involved in controlling nutritional behavior and energy consumption patterns (7). Environmental signals can be divided into two main parts: a) appetite-suppressing signals, such as leptin and peptide PYY3-36, which are involved in long-term energy balance regulation and directly in responding to changes in body proportions, b) appetite increasing signals, such as agouti-related protein (AgRp < /em>) and ghrelin, that are involved in acute control of nutritional behavior (8, 9). Recent research suggests that high intensity interval training (HIIT) creates a transient anorexia nervosa that delays the feeling of hunger for a short time after exercise, but this effect is short-term. By focusing on HIIT, one can see the possibility of changing energy consumption through changes in hunger and appetite signals as well as regulatory peptides from short to long signal levels (17). In this article, first, the mechanism of action of hormones affecting appetite is explained and then the effect of HIIT on the response of these hormones is discussed. Appetite-suppressing hormones Leptin Leptin is an adipokine secreted from adipose tissue which is a major regulator of inflammatory status and glucose and fat metabolism and can be resistant to insulin (18). Leptin levels are directly related to the body's fat stores and respond to changes in the body's energy balance. Leptin levels in obese children and adolescents are 4 to 5 times higher than in peers who arein normal weight (22, 23). Peptide PYY3-36 Peptide PYY3-36 is associated with short-term appetite which has been observed at different ages of obesity. This anorexigenic peptide covers a wide range of peptides involved in food absorption regulation. PYY is presented in two main forms, PYY3-36 (biologically active form and effective in satiety) and PYY1-36, though many studies have reported total PYY (30). PYY3-36 is released from L cells, especially in the small distal intestine, and is stored at high levels for several hours after eating (34). After absorbing nutrients, the presence of nutrients in the duodenum probably releases a nerve signal or sputum into the distal river that plays an important role in the initial release of PYY3-36, and is then accompanied by direct stimulation of L cells in the ileum. (35). Although some of these peptides are produced and secreted in the brain and hypothalamus, the production of the central and peripheral nervous system and its activities indicate parallel paths in moderating nutritional behavior (36). Appetite increasing hormones Agouti-related protein (AgRp < /strong>) The Agouti-related protein (AgRp < /em>) gene is a candidate for obesity (52) and an appetizing and stimulating appetite-enhancing peptide .It is involved in nutritional behavior or weight regulation and energy homeostasis, and its plasma levels are higher in obese individuals (53, 54). Studies have shown that physical activity under normal conditions causes overeating by receiving energy and stimulating Y neuropeptide activity and the Agouti-related protein (AgRp < /em>) in the hypothalamus (8, 55). The negative energy balance for stimulating appetite and increasing food absorption depends on the severity, duration and the type of the exercise, the initial amount of fuel resources and nutritional status (57). Hunger and exercise increase appetite and lead to an increase in negative energy balance and the amount of appetite-increasing hypothalamic and extra-hypothalamic peptides including the agouti-related protein and neuropeptide Y (55, 58). Ghrelin Ghrelin is a 28-amino acid peptide derived from its precursor, preheproghrelin, which contains 117 amino acids. The ghrelin sequence is located immediately after the 23 amino acids associated with the peptide sign. To detect the hormone, a group of octanivil has been added to the serine amino acid ghrelin No. 3 which is required by the recipient (59). Ghrelin is a hormone that affects the feeling of hunger and long-term regulation of body weight. This peptide hormone is secreted from the gastrointestinal tract, especially the stomach, and plays an important role in increasing the absorption of food and fat mass (61). The findings show that the expression of the ghrelin gene increases during starvation and decreases during satiety. In fact, the plasma levels of ghrelin decrease during positive energy balance and increase during negative energy balance (63). Most studies have shown that fasting ghrelin levels decrease with age (37, 38) and puberty growth in childhood and adolescence (65). High intensity interval training (HIIT) HIIT is a style of training that is attributed to repeated bouts with relatively short interval activities with high intensity or intensity close to the one obtained by Vo2peak (68). Due to the intensity of the training, an HIIT bout may last from a few seconds to several minutes, and various bouts are separated by a few minutes of rest with low-intensity activity (69). There is ample evidence that HIIT has a wide range of cardiovascular and metabolic benefits (increased cardiovascular fitness, mitochondrial biogenesis, increased expression of glucose transporter type 4 (GLUT­4) levels, and insulin sensitivity) as long-term continuous training or even more (71 -74). These can help oxidize much body fat. In this regard, various studies have shown that HIIT can be a cost-effective method of body weight management in obese and overweight people (75, 76). Recent research shows that HIIT creates a state of transient anorexia that delays the feeling of hunger for a short time after exercise, but this effect is short-term. This training also plays a role in changing energy consumption through changes in hunger and appetite signals as well as regulatory peptides at short to long signal levels (17). The regulation of energy balance following HIIT involves an organized action and reaction between the central nervous system (CNS) and various organs that is effective in establishing energy homeostasis (54). On the other hand, producing a negative energy balance through exercise may trigger behavioral stimulation to compensate for nutrition which in turn can neutralize the energy loss caused by activity and can alter its effects on weight loss (79). In general, much of the evidence points to the increased levels of fasting ghrelin with weight loss from training. These results show that weight loss affected by training plays a role in normalizing fasting ghrelin levels in obese individuals (86, 90, 91). Conclusion Most of studies show that HIIT delays the feeling of hunger by creating a state of transient anorexia for a short time after exercise and plays a role by changing the signals of hunger and appetite as well as regulatory peptides from short to long term signal levels.

Despite the increase in urban land per capita, these buildings have caused negative effects in different dimensions due to the lack of proper planning and design. Considering the importance of the subject, the aim of the current research is to investigate the physical-environmental consequences by the increase in high-rise construction in Tabriz metropolis and to provide suggestions for the construction of future buildings. The research method in the current research is mixed (combination of quantitative-qualitative methods) with an applied purpose and a descriptive-analytical nature, in order to analyze the information, structural equation modeling was used in Amos software. The statistical population of the research includes the citizens of regions 1, 2 and 5 of Tabriz, that is, the residents around Aftab Towers in Valiasr (region 1), Asman towers in El Goli (region 2) and Mehr towers in Roshdieh (region 5), which is in line with determining the volume Cochran's sampling method was used and the sample size was determined to be 384 people. The findings of the research show that the most important physical-environmental consequences caused by high-rise construction in Tabriz metropolis are related to air pollution components, surrounding functions and uses, and visual effects. Also, among the sub-components, the most important consequences are related to reducing the capacity of the road network, increasing air pollution, imposing additional pressure and load on urban facilities and services, and visual disruption, for which the value of the structural model is 0.91, 0.85, 0.77 and 0.71 respectively.

This phenomenon, when it persists for longer durations, may cause environmental and agricultural damage. The objective of this research is to extract and introduce synoptic patterns that lead to the creation of heatwaves in the southern coastal cities over the past 33 years. To achieve this goal, using the Z-score index and other selected criteria, heatwave samples were extracted for all selected stations. Based on the selected criteria, 90 heatwave samples were extracted for the 33-year statistical period. Then, using the factor analysis method and visual inspection with 1000 hPa weather data, dominant and frequent synoptic patterns were extracted. The results of this research showed that seven factors and 14 frequent patterns are the most dominant synoptic patterns that create heatwaves during the cold season in southern Iranian cities. Among these patterns, the first factor of the Sudan-Turkmenistan low-pressure pattern and, among the effective systems in creating high heatwave temperatures, the Sudan low-pressure system had the most significant role in the structure of synoptic patterns. In this pattern, the Sudan low-pressure system is combined with a northeast expansion towards the South and the warm air movement of the Hadley cell, causing an abnormal rise in temperatures at coastal stations. The core heat of this pattern is located over Sudan and Saudi Arabia.

In this research we proceed to synoptic and thermodynamic of torrential flooding of 28 to 31 july2015 in the half north, west and central of the country. First with using territorial stations data the precipitation of under studied stations analyzed and then with using upper atmospheric data and tracing the related maps, precipitations analyzed. The results showed that spreading the black sea high pressure on north half of the country and penetrating the Warm low pressure of Persian Gulf-Pakistan from south, meanwhile, northern flowing cause severe gradient pressure in the sea level. In the middle levels stretching the trough axis from central Asia till south of Iran cause severe ascending of air. Analyzing the omega maps on Iran indicates the settlement of maximum negative omega in north of Iran. Also analyzing of moisture advection showed that in the levels of 1000 and 850HPA, the black and Caspian seas are the sources of supplying moisture. But in the levels of 700 and 500 HPA, the Oman and Arab Sea and India peninsula has the main rule in transferring the moisture on the studied region.The point worthy of attention is that the jet stream located only above the level of 300 hpa and upper the latitude of 38 northern degree and out of the occurrence boundary of supper heavy precipitation of ending days in July 2015.And it's impact was indirect which caused offloading the warm and humid air to the through and consequently strengthen the instability.

The study employed a sequential explanatory mixed-method design, consisting of two phases for data collection and analysis. In the quantitative phase, 40 male and 40 female students aged 16-18 were conveniently sampled from tenth-grade high schools in Lahijan, Iran. They were divided into two experimental and two control groups. The experimental groups received instruction using the team-teaching model, while the control groups received traditional instruction. Data analysis was conducted using one-way ANOVA, which revealed a statistically significant improvement in the performance of the experimental groups compared to the control groups. Due to gender differences, the results showed no significant disparities in the outcomes achieved by male and female students. In the qualitative phase, the same participants from the experimental groups were asked to provide open-ended responses regarding the advantages and disadvantages of the team-teaching method, using a questionnaire developed by Jones and Harris (2012). The responses were carefully examined using open coding techniques, and common themes were identified through systematic comparison of the codes. The findings indicated that team-teaching offered a wide range of benefits. Considering gender differences, it was evident that male participants perceived the benefits of the team-teaching model to outweigh the drawbacks more than their female counterparts. These findings have pedagogical implications for Iranian teachers and theoreticians in the field of English language instruction. Manuscript profile -

Type I consists of functionally graded layers coating a homogeneous core, while type II features an FG core covered by homogeneous face sheets. All materials are considered temperature dependent, with FGM properties modified through even and uneven porosity distributions modeled by a power law rule. The sandwich beam theory was adjusted to account for nonlinear Lagrange strains, thermal stresses of the face sheets, in-plane strain, and the transverse flexibility of the core. The governing equations were derived from the minimum potential energy principle, and a Galerkin method was employed to solve them for simply supported and clamped boundary conditions. Comparisons with existing literature demonstrate good agreement. The resultes showed that critical load parameter decreases with increasing temperature, power law index, length-to-thickness ratio, thickness, and porosity volume fraction in both distributions, but increases with the wave number. Additionally, the stability of type II sandwich beams surpasses that of type I in high-temperature conditions. Manuscript profile -

These sources can deliver their energy to the grid or directly to the consumer. Usually the voltage level produced in these sources is low and the need to increase the voltage level is. To solve this problem, high voltage gain converters can be used as single-port and multi-port. In the proposed converter to increase the voltage gain, the voltage multiplier circuit, the switched inductors and the switched capacitor are used, and also the clamp circuit is used to solve the problem of energy stored in the leakage inductor. One of the features of this converter is to share the components of the converter in different modes. This is important to reduce the number of semiconductor elements in the construction of the converter. In the proposed converter, the power transfer can be from solar array to load or from solar array to battery or both. Also, in peak moments, solar array and battery consumption can provide load power at the same time. In this paper, theoretical analysis has been used to evaluate the performance of the proposed converters and the results of the converter simulation in Orcad software have been presented to evaluate the accuracy of the theoretical analysis. Finally, a laboratory sample of the proposed converter with a power of 200 watts and a frequency of 100 kHz has been implemented, Manuscript profile -

Since the proposed converter gain is much lower than the conventional buck converter, it does not have the problems of these converters such as narrow duty cycle, high voltage stress and high switch current, etc. In the proposed converter, the voltage stress on the switch is reduced, so a switch with lower drain-source resistance (RDS(ON)) can be used and the conduction losses are reduced. On the other hand, because the diodes of the circuit are switched off under zero current switching condition, do not have the problem of reverse recovery. Switching losses of the switches are also greatly reduced due to operating under zero voltage switching conditions. The proposed converter has been thoroughly analyzed and a practical 120 W prototype has been made to prove the correctness of the circuit analysis. Manuscript profile -

The proposed auxiliary circuit has the coupled inductor with the input inductors of the converter and provides zero voltage switching conditions for the main switches of the converter. On the other hand, auxiliary switches and diodes of auxiliary circuit operate under zero current condition and therefore do not impose significant losses on the converter. The auxiliary circuit is modular and can apply to more phases of the converter. Therefore, the converter can be easily designed for very high power applications. The proposed converter uses the cross-coupled inductors technique with series lift capacitors to increase the voltage gain and reduce the voltage stress on the main switches. Also, leakage inductance energy can be easily absorbed by the clamp capacitors and helps to increasing the voltage gain. The proposed high step-up converter has been analyzed in detail and a practical prototype has been implemented at 100W.

On the other hand, the output diodes operate under zero current switching and do not have the reverse recovery problem. The converter is also controlled by pulse width modulation, and since the auxiliary switches are turned on in complimentary with the main switches, they do not have a complex control circuit.

Among the active materials used in modulators, graphene and indium tin oxide (ITO) are some of the suitable options among the active materials for modulation action due to their epsilon-near-zero (ENZ) characteristics, speed, and considerable response. In this paper, by applying direct coupling of light, the structure of plasmonic modulator in three-dimensional mode has been designed. And by changing the thickness of ITO, HfO2 (hafnium oxide) layers and waveguide width, the structure is optimized. Optimization thickness of 3 nm for ITO, 5nm for HfO2 and 280nm for waveguide width is achieved. The results of three-dimensional simulations of this paper with appropriate coupling show that the insertion loss (IL) of three-dimensional mode have not changed and the extinction ratio (ER) of the modulator has been slightly reduced in comparison with two-dimensional mode .On the other hand, appropriate and optimal coupling has no effect on energy consumption.Three-dimensional results show that the proposed plasmonic modulator can achieve an extinction ratio of 13.9 dB, an insertion loss of 2.9 dB, modulation speed of 140.9 GHz and a very low power consumption of 1.51 fj/bit for a 1µm length of the modulator, at 0.5 V voltage and a wavelength of 1.55 µm. Our design demonstrates a considerable reduction in energy consumption and improvement in extinction ratio compared to previous works. Also, for a 2 µm length of the modulator, an extinction ratio of 27.76 dB, an insertion loss of 5.68 dB, modulation speed of 70.14 GHz and power consumption of 2.88 fj/bit is achieved.

Memristor can become an essential element of SRAM and DRAM caches because of its zero power consumption in data storage and non-volatile state. It can effectively improve the efficiency, speed, and power consumption of circuits. In this paper, we propose a 4T1M memory cell reducing the cell area by maintaining the maximum properties of 6T1M. To simulate the proposed memory cell, the length of the memristors is 10 nm, and the resistance of their on and off states is selected as 1 kΩ and 200 kΩ, respectively. Also, the cell MOS transistors are simulated by the 32 nm HP CMOS PTM model. Simulations in H-Spice software, at 0.9 V power supply, have been conducted to compare the proposed cell characteristics with two conventional six-transistor (6T) and six-transistor one-memristor (6T1M) cells. The results show that using a memristor in a memory cell causes zero power consumption during data storage for a long time and reduces the occupied area by 36.7% compared to the 6T1M cell. The speed of writing “1” data on the proposed cell is only 30 ps, which shows a 3-fold improvement compared to the 6T1M cell, but no significant change is observed when writing “0” data. The static power of the proposed cell is 133 times less than that of a six-transistor cell, and its dynamic power is about the same as the 6T1M cell, but it consumes 60 times less energy than a six-transistor cell.

Due to sudden changes in load or input voltage level, the converter used as a voltage regulator in a certain range of output voltage changes should quickly return to its reference value, which should analyze the dynamic behavior of these converters and the speed of its dynamic response to any interference is discussed. Because the initial boost converter has a delay in its transfer function due to the right half plane zero, it is possible to use structures to eliminate this delay. The use of coupled inductor in non-insulated structures is one of the structures that can be repaired in this field, which in addition to removing right half plan zero of the transfer function, increases voltage gain, reduces voltage stress on circuit semiconductors. In this paper, a new coupled inductor structure is proposed to remove the right half plan zero. The new structure will be accompanied by an increase in gain, but the voltage stress on the switch is limited, and on the other hand, due to the position of the coupled inductor, the input current for this structure will be minimized.

Then, to improve the dynamic stability of the power system, the use of an optimized supplementary controller in the VSC HVDC system will be proposed. The proposed controller is added as an additional loop to the converter control circuits in VSC HVDC and will amplify the damping torque in the generators by correcting the damping coefficient of the system oscillation modes. In addition, a solution is provided to use the supplementary controller in the most optimal path, so that the most controllability on the oscillation modes and the least interference with other channels between the input-output signals are provided. To design the proposed controller, a fractional order PID controller will be used whose coefficients are adjusted through an optimized exchange market algorithm. The optimization of the algorithm is done by using mutation and crossover operators in the genetic algorithm with the aim of avoiding bats being trapped at local extremum. The simulation results show that the method proposed in this paper not only improves the dynamic stability of the power system but also strengthens the voltage profile. Manuscript profile -

An auxiliary circuit with minimum number of elements is added to the converter to provide the soft switching conditions for all the semiconductors solving the reverse recovery problem of the diodes, and reducing the conduction and the switching losses of the power switches. Moreover, there is only one magnetic core used in the converter decreasing the copper resistance; thus, the power losses and the electromagnetic interference of the converter is reduced so the efficiency of the proposed converter compared to the conventional hard switched boost converter, is improved. Further, in order to adjust the output voltage of the proposed converter to the desired value under the load variations, a PI controller has been applied to the output of the proposed converter and its operation is simulated by MATLAB. In order to verify the theoretical analysis of the soft switching operations, a 250W prototype is implemented and its experimental results are provided. Manuscript profile -

The proposed converter is a boost converter combined with two voltage multiplier cells for boosting output voltage. Also, extend voltage gain of the proposed converter is achieved by using a coupled-inductor. Compare with other similar high step-up topologies with the same number of components, the proposed converter has a higher voltage gain and higher efficiency. An active clamp circuit is used so, the zero-voltage switching (ZVS) is achieved. Also, in the proposed converter, the voltage stresses on the switches are low. As the voltage stress decreases on the switch, Ron of the MOSFET is deceased and as a result conduction loss of the switch is decreased. So, the efficiency of this converter increased. In this paper, operational principle of the converter is described and the analytical, simulated results and prototype converters are validated using a 20V input and 400V output converter at 200W load.

Therefore, it no needs extra driver circuit and control circuit is simple. Also the energy in auxiliary circuit transfers to the output. The auxiliary circuit provides zero current condition for turns on and zero voltage condition for turns off instants of the switch. In addition all diodes turn off under ZCS condition and reveres recovery problem don’t exist in them. One of the advantages of the proposed converter is the reduction of the voltage stress across the switch due to its high voltage gain. Also, the auxiliary circuit has a low number of elements; therefore, high conduction losses do not impose on the converter. The coupling inductors in the auxiliary circuit have low values, so the volumes and parasitic magnitudes do not increase. To verify theoretical analysis a prototype of the proposed converter is implemented. Manuscript profile -

As a result, it is necessary to develop new energy that is clean and renewable to replace of fossil fuels. Solar energy, photovoltaic power generation, fuel cell and hydrogen energy are methods used to big - scale energy sources.In a mono - phase system with two - step structure if the line voltage is 220 volts, bus inverter voltage that connected to network, should be about 380 volts. However, the output voltage of the photovoltaic cells and fuel cells are generally between 25 to 40 volts this voltage is much lower than the bus voltage. So a high efficiency DC-DC converter output voltage is required to boost fuel cells and photovoltaic cells. In this research, will be presented an improved structure as high efficiency voltage boost converter with a voltage multiplier circuit for solar cell applications. In the proposed structure for efficiency improvement, used voltage multiplier circuit techniques and coupled inductors. We have the proposed converter using the active clamp circuit to achieve soft switching conditions and reduce switching losses. generally, the advantages of the proposed converter are high step-up voltage and high efficiency, low voltage stress for switches and diodes, providing soft switching conditions, and ultimately reducing the number of magnetic elements and the circuit's size.

Solar or photovoltaic systems are one of the most widely used renewable energy sources that have a low output voltage. For this reason, research on dc-dc converters has increased in recent years. In this paper, a non-isolated high voltage gain converter with three input-output ports is proposed. This converter provides two separate paths for power flow from each input source to the output load. In order to reduce the number of converter components, some components play multiple roles. Therefore, the energy storage device (battery) will charge with the same components used to transfer the power to the load. In this converter, to increase the voltage gain, the coupled inductor technique is used. Moreover, to reduce the leakage inductance as well as achieving the soft switching condition, two active clamps are used. Since the voltage across the switches is limited, the switches can be used with low voltage stress and thus low conduction losses. In this converter, the ripple of the input current will reduce by adding an inductor at its input. This has a significant impact on the performance and the lifespan of the solar cells. The various operational modes of the converter are discussed and the designing considerations are presented. A prototype of the proposed converter is simulated to supply a 130 W, 330 V load with a switching frequency of 50 kHz, in OrCAD software. Finally, a laboratory sample is implemented and the theoretical analysis are validated by the practical results. Manuscript profile -

Meanwhile, synchronous converters have received a lot of attention due to the non-dependence of the voltage conversion ratio on the load and the continuity of the inductor current. But the switching of these converters takes place at higher power levels at lower frequencies. For this reason, the switching circuit must work with a higher dead time. In this article, an analog application circuit design without the use of a microcontroller is presented for the switching of the synchronous buck converter, which, while ensuring that pulses are not sent to the keys at the same time, the amount of dead time can be It provides a setting that can be changed according to the voltage level and current of the circuit. After analyzing the conditions at the moment of switching on and off of the circuit, it was found that at the moment of switching off, a destructive transient current is applied to the keys, which this article solves this issue by using two fast SSR relays in the path of the input signal to the gate module. The driver suggests that it has been tested on a prototype device. This article also mentions the requirements of the switching circuit by analyzing the conditions of the moment when the circuit is turned on and off, so that the transient damaging current does not pass through the IGBT. The results of experimental tests on a 15 kW synchronous buck DC/DC converter with an output of 300 V 50 amps show that the well-designed switching circuit creates an adjustable dead time of up to 6 microseconds in the switching of this converter and the continuity conditions It has provided the inductor current both in no load and under load. Also, the proposed method has well removed the transients of the circuit turning on and off. Manuscript profile -

The auxiliary circuit not only uses the leakage inductance energy to increase voltage gain but also reduces switching and conduction losses of the semiconductor devices. The auxiliary circuit has only one snubber capacitor and one auxiliary switch, and the circuit capacitors are used as clamp capacitors. The low voltage stress of the switches makes it possible to use cheaper switches with more minor drain-source resistance. Also, the lifting voltage capacitor absorbs the leakage inductance energy. Due to zero voltage switching of switches, there are no capacitive turn-on losses, and due to switching off the diodes at zero-current conditions, the reverse recovery problem is solved in them, so the conduction losses of the converter are significantly reduced. On the other hand, the ripple input current in the converter has been dramatically reduced, which makes it very suitable for use in photovoltaic systems. The converter is implemented at 200 W and 350V output and the practical results confirm the theoretical analyzes. Manuscript profile -

Concrete specimens which were prepared on standard methods were divided into control and treated ones from which the formers were just exposed to saturated situation(which attained compressive strength of 884.54 Kg/cm2 at 28 days) while the other 3 sets were cured as follows: First and second part were placed under saturated situation for one to three days but the remaining one) was directly transferred to autoclave. All of these 3 sets were maintained in autoclave for 15 to 150 minutes. Results showed that specimens kept in autoclave for 15 minutes (without any maintenance at saturated situation), attained compressive strength of 748.73 Kg/cm2 while in the case of the ones kept at saturated situation for one-day (before autoclave) the compressive strength to 834.71 Kg/cm2 which was about 84.65 and 94.37% of compressive strength of the control sample at the age of 28-days respectively. By increasing the autoclave time to 30 minutes, the compressive strength of the specimens under two circumstances mentioned above improved up to 892.40 Kg/cm2 and 903.51 Kg/cm2 respectively which was about the compressive strength of the check specimen in 28 days.

In this regard, the application of various bracing systems in the construction of high-rise buildings, such as steel and concrete shear walls is a common solution. Therefore, in this research, once considering the soil-structure interaction and again without considering the impact of this interaction on two 10 and 15-story structures, different models of ABAQUS software were presented in the presence of steel and concrete shear walls. The nonlinear analytical method was investigated. For this purpose, by modeling the structures mentioned in the software, the effect of using steel and concrete shear walls was analyzed in terms of the impact of soil-structure interaction and without it. The results of modeling for 10-story structures showed that the performance of the structure with steel shear wall is better than concrete shear wall. In addition, the results obtained for the 15-story structure showed that the performance of this structure with steel shear wall was better than concrete shear wall. In general, the results present that the steel shear wall exhibits better behavior than the concrete shear wall. In general, it was found that by taking into account the soil-structure interaction in the modeling performed for both types of structures, the outputs are closer to reality. Manuscript profile -

This issue is of particular importance, especially in tall embankments, based on loose platforms with little or no bearing capacity. Among the existing methods to improve the embankment and the bedding in the railway lines, installation of micropiles for fixing the embankment and the bed, which does not block the line and stop the traffic, is preferable. In the present paper, a parametric study was carried out; using ABAQUS, for high rise embankment improved by micropiles with different patterns, operational loads, railroad traffic and severe earthquakes, using the LM71 loading standard. The results indicate that the factors affecting the pattern of the microplots generally include the distribution of loads, shear parameters and bearing capacity, depth of the micropiles and geometric characteristics of the embankment. It should be noted that the optimum arrangement of micropiles for improvement, is the length between the toe and 0.25 to 0.5 percent of the slope length, which reduces the maintenance and handling cost.

One of the most important disadvantages of this system is the shear lag phenomenon, which increases the axial force in the side columns and decreases the axial force of the middle columns of the flange of structure. Therefore, in this study, the shear lag is investigated in high-rise reinforced concrete structures with tube-in-tube system with and without columns cut according to the height and plan under the effect of wind load. Thus, two high-rise concrete buildings, 40 and 60-story are modeled in ETABS 2017 software three dimensionally in three states. 40-story and 60-story prototypes are considered with and without columns cut in stories 11, 21 and 31, and then in stories 16, 31, and 46, respectively. Models were analyzed by wind force in order to calculate and compare the shear lag phenomenon. The results show that shear lag index has been changed from positive to negative phase at the height of building from the bottom to top and the axial force of the middle columns is higher than the corner columns in top stories. For example, the shear lag indices average is 1.2 and 0.61 in the 5th and 35th floors of 40-story building without column cut, respectively. Then the above values are 0.52 and 1.14 in the 5th and 55th floors, respectively for 60-story building without column cut. Also, the results indicate that the performance of structures has been improved at height by bundling of the columns in structures. Manuscript profile -

The selected accelerograms were related to the Chi Chi, Landers, Loma Prieta, Northridge, Parkfield, San Fernando and Tabas earthquakes which were selected and scaled according to Iranian Standard No. 2800. These accelerograms were related to the stations which were registered at the distance of 20 to 60 kilometers from the fault and did not have the near-fault earthquakes characteristics such as forward directivity and fling step and etc. Furthermore, the magnitude of all the selected earthquakes was between 6.5 and 7.5 Richter. Then, nonlinear time history analysis was used to investigate and compare the seismic response of the studied building in cases with and without using the rocking system. The results of studies (including base shear, drift, displacement of roof, acceleration of roof and etc.) indicated that using rocking system in the high-rise steel buildings could cause significantly reduce the seismic response of high-rise steel buildings.

In this study a high-Rise, 20-Storey, three-dimensional reinforced concrete frame with 8 Models, of which 4 models with moment frame structural system and 4 models with moment frame + viscoelastic damping system in two directions of X, Y located in the high seismic zone (A=0.3g) on the soil type III is considered. The aim of the present study is to investigate the horizontal lateral displacement (absolute and relative) of the stories, the base shear of frames under gravity loads, and lateral loads of the earthquake. In order to modeling the viscoelastic materials, the Kelvin-Voigt model and to determine damping ratio(ζ) of frames with viscoelastic damper, stiffness coefficient (Kv) and damping coefficient (Cv) of viscoelastic dampers, the modal strain energy method have been applied. For seismic analysis of models without and with dampers, dynamic analysis of nonlinear time history via direct integration and modal (FNA) methods have been utilized, respectively. Geometric modeling of all frames was done using the SAP2000-V15 software. The results indicate that with increasing span length (model 2 compared to model 1 and model 4 compared to model 3) and increasing the height of stories (model 3 compared to model 1 and Model 4 compared to model 2), the maximum absolute lateral and relative displacement of stories, and base shear along with X, Y without and with viscoelastic damper have an increasing trend.

Adopting a descriptive survey, the statistical population of the study included graduate students of Islamic Azad University of Sari Branch. Using Krejcie and Morgan table, 331 were randomly selected. The research instruments were researcher-made information technology literacy questionnaire and critical thinking questionnaire, the validities of which were confirmed by the experts in the field of educational sciences. The reliabilities for the given questionnaires were estimated through Chronbach's alpha coefficient by distributing the questionnaires among a group of 30 participants, the result of which was 0.93 for IT literacy questionnaire and 0.80 for critical thinking skills. Regarding the establishment of parametric statistics, the Pearson correlation was used to analyze the data. The results of the study showed that there was no relationship between IT literacy and critical thinking skills (creativity, maturity and commitment) among higher education students. It means that IT literacy was not a reason for the existence of critical thinking, perhaps the best time for improving the thinking power among people through using information technology is before their entrance to higher education.

Using phenomenological research method, purposeful sampling and deep semi-structured interviewing tool, mental perceptions of sixteen people (eight master and eight e-courses students) were analyzed. Then data was analyzed using van menon method. The findings of the research led to the identification of the three main axes and the twelve axis. The main pillars include ethical bottlenecks related to professors, students and universities. Master related ethical bottlenecks include violation of privacy, limitation of access to professors, weakness of teacher and student relationships, and lack of ethical modeling of instructors. Student ethical bottlenecks include academic intolerance, promotion of deception, diminished commitment and ethical adherence, and the misuse of technology. The ethical bottlenecks related to the university include the lack of educational aspects, lack of responsiveness to students, lack of skills and deficiencies in the assessment system and the existence of score bubbles. the results showed that; despite the unique opportunities of e-learning, due to the lack of face-to-face communication and the lack of student ethical modeling, the student's actual behaviors do not provide much ground for moral development, But this vacuum can be filled by interacting with the learning environment and using more multimedia technologies.

This study investigated the effect of ethanol extract of Bryophyllum pinnatum leaves on the biochemical indices of high salt-fed albino rats.Experimental: Twenty-four male healthy albino rats weighing 110-150g were randomly divided into four groups of six rats per group. Group 1 was administered with feed and water, which was the normal control. Group 2 was administered with 10 mL/kg of 18% NaCl only (Negative control), and groups 3 and 4 were administered with 10 mL/kg of 18% NaCl as well as 200 mg/kg and 400 mg/kg of the extract, respectively.Results: The acute toxicity of the methanol leaves extract of Bryophyllum pinnatum in rats recorded no mortality even at a high dose of 5000 mg/kg body weight of the animal, thus LD50 could not be determined. The negative control group was significantly (P<0.05) higher in alanine aminotransferase (ALT), alkaline phosphatase (ALP), aspartate aminotransferase (AST) activities, cholesterol (CHOL), triacylglycerol (TAG), low-density lipoprotein (LDL) and bilirubin level when compared with other groups. There was a significant reduction in the Urea and Creatinine levels in the group administered with 400 mg/kg extract. The administration of high salt (18%) increased serum levels of AST, ALT, ALP, Bilirubin, Urea, creatinine, TAG, Cholesterol, and LDL and reduced the high-density lipoprotein (HDL).Recommended applications/industries: The result of the high salt-fed untreated rats suggested inflammation of the liver and lipid dysfunction; however, the extract showed a highly potent effect in preventing cell damage that could be caused by high salt intake.

In this paper, in addition to evaluating the relationship between two main variables, other factors that can affect urban crimes are also examined. The research population consisted of the residents of regions 5, 6, 7, 8, 12, 13, 14 in north and south of Isfahan. The findings showed that the linear relationship between high rising buildings and urban crimes is low. In general the increase of high-rise building caused 6.5% increase of urban crimes. On the other hand, with the score of 0.92, there is a very strong nonlinear relationship between two mentioned variables. Among four groups of urban crime, Pearson coefficient for crimes against properties and ownership is 0.47 and Spearman coefficient is 0.6, which is the strongest relationship of variables considered. This indicates that the probability of committing a crime in high rise building areas like region 6, increases, perhaps because of the relatively good economic situation of the residents. Considering the effects of intervening variables, the results showed that better employment conditions, durability and age of buildings decreases urban crimes. Manuscript profile -

In this research, Rumi's linguistic changes in Shams lyrical poems have been analyzed. For this purpose, Shams Tabrizi Sonnets with Kadkani introduction and selection, were selected as the statistical sample of the research and were studied to identify the instances of linguistic changes which were then classified to two categories: lexical and syntactic changes. Subsequently, the lexical changes were categorized to three classes: structural, phonetic, and semantic. The results show that Rumi has violated the phonetic, morphological, and syntactic rules of the language and has created a novel work. This involvement of Rumi in language has led to: expanding and highlighting the language, and strengthening the musical side of his speech. The abundance of some of these changes is so high that it can be considered a stylistic feature of Rumi's sonnet. Manuscript profile -

Ultimately, by using a pairwise comparison questionnaire, the required data was extracted from 11 experts of the technical and vocational university, and by using the causal mapping approach, the successful brand model was designed with the integration mental map of the experts. The findings of the qualitative phase showed that a successful brand in higher education consists of 6 components, which were divided into university image, costs and financial matters, university services and facilities, advertising and external communications, planning and success of education and the location of the university. The highest relationship between variables is related to the relationship between university services and facilities with costs and financial items. Then, between the university image variables and university services and facilities. The weakest relationship is between the cost and financial variables with the university image and educational planning and success with costs and financial items. Successful brand consists of university image, costs and financial matters, university services and facilities, advertising and external communications, planning and success of education and the location of the university.

One of the problems is horizontal and immethodical expansion that has caused traffic, more use of energy, more environmental pollution and social isolation. If urban management is trying to control and reduce the urban problems to present urban expansion models, then it should reconsider urban planning methods and create efficient models in urban environments.This essay is aimed to present modern and efficient methods of urban structures by clarifying the infill development model and urban high-rise construction method and is also trying to answer the question that: " Can high-rise construction be an acceptable method of urban endogenous development in Bojnurd as a medium-sized city? " by conducting library and field studies and a practical research method.Bojnourd is a medium-sized city in the northeast of the country.The city has an area of more than 3,000 hectares and a population of about 250,000. The results show that Bojnurd expansion has faced urban sprawl over the past 20 years and about 70 hectares have been added to the city area while the available area of the city has the endogenous development potential and standard compact construction; and checking the population compaction, land value and urban pathways capacity and the questionnaire outcomes done by urban managers show that in some peripheral areas of the city, there is the potential of high-rise construction up to 6 floors in order to prevent the immethodical city expansion.

On the other hand, people are more likely to use open urban environments to meet their biological needs. In this regard, various factors such as forms, heights and green facade of buildings and the presence of continuous stream of wind can play a significant role in the distribution of pollutant particles. The present study aimed to investigate the effect of the forms and heights of high-rise residential buildings on the distribution of pollutant particles, by recognizing district one of Tehran's urban air flow. To this, a library research method was used to collect information, analytical-descriptive as well as computer simulation with Envi-met software and ANSYS to select the appropriate model. According to the modeling done for the nine different types of building with different forms and heights, it was concluded that changing these factors in residential building on the air flow Natural and wind speeds affect thus affect the distribution of particulate matter. In this study, the results of modeling show the residual amount of particulate matter around 9 tall building models, of which the square shape with 20-degree height in the specified position is more suitable than other options.

This research investigates the effect of the physical factors of the atrium on the thermal performance, lighting and ventilation of high buildings in the climate of Rasht city. Methodology: The main approach of the research method of this study is quantitative and uses the simulation method. The simulation reference building is a high building with ten floors and a square plan with an open interior design, with a rectangular atrium exactly in the center of the building, defined so that the center of the atrium is located on the center of the building. The indicators of energy performance and ventilation performance including cooling demand, heating demand, total energy consumption, indoor air temperature and the number of air changes throughout the building are considered as dependent variables, and the variables of land dimensions, building form, window-to-wall ratio (WWR) and internal plan are fixed as a control variable. Result and Discussion: The findings show that, in general, the change in the physical factors of the atrium directly affects the thermal performance, lighting and ventilation of high buildings in the climate of Rasht city. Also, the findings show that the variables of length, width, perimeter and area of the atrium in the reference model in the climate of Rasht city have a significant and direct relationship with the heating demand and ventilation volume and an inverse relationship with the lighting demand of the building. The results showed that the cooling demand constitutes the largest amount of energy consumption, i.e. about 74% of the total energy consumption. Also, the heating demand is about 17% of the total energy consumption on average. While lighting energy defines the lowest amount of energy consumption, on average 9% of the total energy consumption. Conclusion:According to the findings, it is concluded that the use of atriums in high buildings in Rasht city is recommended only in situations where there is an urgent need to increase the lighting in the heart of the building;. Also, based on the findings, it can be concluded that in an equal area, the use of a square atrium generally produces better results. Also, rectangular atriums with north-south orientation have a better response in terms of energy performance than other orientations in Rasht city. Manuscript profile -

Mulberry has improved through conventional breeding in general aims to improve the quantity and quality of leaf yield, which have direct bearing on silk productivity. Leaf senescence is one of the major constraints, which restricts the quantity of quality leaf availability for silkworm rearing. High yielding mulberry varieties often show leaf fall in the range of 20 – 33% in tropical sericultural belts. Hence, in order to increase the leaf availability, it is essential to delay the senescence of leaves. Keeping this in view, the present study was undertaken on 9 mulberry genotypes, which were developed systematically for delayed senescence. The interrelationship among factors that contribute to growth, yield and low foliar senescence were investigated. Correlation between agronomic traits and leaf yield revealed the existence of strong positive associations among plant height, total shoot length (TSL), nodal distance (ND), leaf fall (LF), number of leaves/ plant (NLP), fresh and dry weight of 100 leaves (FWL & DWL), leaf area (LA), leaf area index (LAI), above ground biomass (AGB) with leaf yield. However, leaf harvest index (LHI) had a strong negative correlation with leaf fall % and leaf yield. Significant improvement in the important growth and yield attributing charactersviz., FWL, DWL, LA, AGB, LHI and LAI contributed to a higher yield in CT44. Path co-efficient analysis revealed the direct positive effect of the characters viz., AGB (1.233), LHI (0.449), NLP (0.217), and LA (0.181), on leaf yield. From the studies it is concluded that low leaf fall coupled with high LHI can be considered for the selection of varieties with delayed leaf senescence in mulberry. Manuscript profile -

Then, each plot was divided into two parts. The upper part of plot was not weeding and was considered as a control and the lower part of the plot was removed by hand weeding. Based on the results, the effect of planting date and cultivar on biological yield, grain yield, and the number of spikes per square meter under weed control conditions was significant at the level of one percent. In this experiment, the highest yield was observed on the date of the first planting in the high-yielding cultivar Shafagh and at the rate of 5253 kg/ha. The results showed that grain yield loss due to weed presence was different depending on planting date, so that the highest and lowest production loss with the average of 1815 and 1090 kg/ha was related to the first and third planting date, respectively. Among rice cultivars, a decrease in grain yield of 40.85 and 32.95 percent was observed in high-yielding cultivars and local cultivars, respectively. Manuscript profile -

Cross sectional data generated from 160 smallholder farmers randomly selected from 2 out of the 3 agricultural zones in Imo State were used. Profit function was used in analyzing the data. Results showed that the LEIT farmers achieved higher level of economic efficiency relative to their HEIT counterparts, although the difference is statistically non significant. It is therefore recommended that in the face of escalating costs of fertilizer, organic manure could be used. Appropriate policies should be put in place by the government to encourage livestock rearing so as to effectively utilize their bye product-organic manure. Household refuse or bio-degradable from the cities could be channeled to farms to serve as organic manure. Manuscript profile -

The higher education s MoreOrganizational agility with a behavioral approach is one of the issues that explaining its various dimensions and angles in different organizations, provides a favorable position for growth and improvement of their performance at different levels. The higher education system is one of the organizations that should identify the drivers of change and take steps to respond to environmental changes and increase agility by strengthening human resources. Referring to the importance of the subject, the present study was conducted with the aim of designing a model of organizational behavioral agility in the higher education sector using a mixed method. In the qualitative section, using the Meta-synthesis method, after screening 481 articles, 120 articles were reviewed, of which 11 factors were introduced as the final factors of the Meta-synthesis. In the quantitative section, the enumerated factors were examined in terms of effectiveness, effectiveness and internal relations using the opinions of 14 members of the panel of experts and the application of DEMATEL technique. The results show that the criterion of "ability to respond to environmental issues" has the highest among other criteria and the criterion of "change in educational planning" has the least impact on other elements. The highest permeability was related to "formation of virtual educational and research programs" and the lowest permeability was related to "managers' support". It was also found that the variables of "ability to respond to environmental issues", "practical skills" and "adaptability" can be considered as independent variables among the variables of organizational behavioral agility.

Methods: Thi MoreObjective: The purpose of this article is to explain the relationship between knowledge management and educational affairs through explaining the basic components and main elements related to the aforementioned fields based on influential conceptual models. Methods: This descriptive-analytical article explained the research back ground in the relations between knowledge management and education in Iran based on the documentary research method. In the explanation of the mentioned relations, the influential international conceptual models have been interpreted and analyzed to clarify the related process. Resultss: Knowledge and knowing are considered as the two main infrastructures in the field of educational affairs and the establishment of knowledge-based systems. From another perspective, tacit and explicit knowledge and the relationship between them are considered as a basis for the historical root of the application of knowledge management in education. The relationship between different types of knowledge leads to the development of individual, group and organizational knowledge. The systematic and internal relationships between educational fields, especially higher education and the knowledge management process can be analyzed by explaining the main elements of education and the knowledge management cycle. In rooting out these findings, three international authorized and valid conceptual models, including Knowledge and Knowledge Matrix, SECI conceptual model and Knowledge Management Framework for Teaching Universities have been interpreted. Conclusion: The process of adaptation and knowledge exchange as the main components of knowledge management is fully related to the goals of educational affairs in knowledge-based empowerment and knowledge enhancement of all stakeholders in the field of education. Thus, in any knowledge dissemination program, the content of education, that is, knowledge and how to transfer it through knowledge management mechanisms should be taken into account for the learner as the end user.

Methodology: the method of this research was descriptive (survey) research, and statistical population of it included all students that enrolled in all branches of Payam-Noor University of Hamedan province. The total number of those were 28530 people. For sampling ofpopulation, a cluster sampling method was used. On the basis of this method, the 387 subjects were selected. For gathering of dada a research-made questionnaire was used. This questionnaire has made based on the Likert scale (very high, high, moderate, low, and very low). The component of scale (questionnaire) included 5 standard competency of ACRL. The questionnaire included 30 items in the form of self-report statements. For becoming suitable of items, the discriminative power method was used and formal, content and constructive (convergent validity and factor analysis) methods were used for validating of it. Based on the convergent validity, the correlation coefficient between my questionnaire and Asgharnia’s Questionnaire (2009) was 0.77. Also, results of explanatory factor analysis on the items of questionnaire lead to extraction of 6 factors with a total cumulative variance explained nearly 66/5%. Also, on the basis of confirmatory factor analysis, the 5 factors with a total cumulative variance explained nearly 63%, were extracted. For making items reliable, the Cronbach’s alpha was used (α=0.94). Findings: in general, results show that the research-made scale (information literacy questionnaire) is a suitable and reliable instrument for assessing the information literacy of distance learner. Also, other result of research shows that the level of students’ information literacy skills at Payam-e-Noor University is moderate. Conclusion: one of the results of this study was that the instrument (scale) is valid & reliable, so using this scale is proposed for assessing of Students’ Information Literacy at other branches of Payam-e-Noor University. Another result of research was that level of students’ information literacy in PNU isn’t desirable and there is a gap between status quo and desirable situation; therefore some interventions (such as: formal and informal instruction) for rising of students’ information literacy is proposed.

In the structure of CSP, the upper rim of calix[4]arne is substituted with two L-alanine units and the lower rim of calix[4]arene is linked to the silica gel by thiol-ene click chemistry. Elemental analysis of the CSP showed 120 μmol of chiral selector bonded per gram of silica gel. 1-Hexene was used for end-capping of unreacted mercapto groups on silica gel. The CSP is chemically bonded to the silica and can be used in the normal-phase mode, reversed-phase mode, and with halogenated solvents mobile phases, if desired. The chromatographic performance of the CSP was evaluated with enantioseparation of the 3,5-dinitrobenzoyl )DNB) derivatives of some amino acids. Manuscript profile -

We also used mean sea level pressure maps to analyze synoptically some special cases of extreme rainfalls. Our obtained results showed significant correlation at 95% level between extreme rainfalls and AO indices and also between rainfall and extreme AO indices in some stations of this region at monthly, seasonal and annual scales. In this context, using multiple regression analysis, rainfall was considered as the dependent variable and features of Siberian high pressure considered as independent variables. Results of this analysis showed that there is a strong relationship between precipitation and features of Siberian high pressure for eastern stations of the region under study in January and February. This relationship was quite evident for western stations in October. In most cases, coefficient of correlation of rainfall with central pressure of Siberian high was negative and, with latitude it was positive. Multiple regression analysis between AO indices and features of Siberian high pressure showed negative relationship between central pressures in Siberian high with AO indices and positive relationship between longitude of Siberian high pressure centers and AO indices in most months of autumn and winter.

The analysis shows that thesuggested mechanisms are all derived from a single model. These theories are different only in appearance. This single model is the basic mechanism of the Caspian Sea rainfall in autumn and winter. Torrential precipitation more occurs in autumn and less in winter. In this paper, winter floods in Noushahr city in 2012 have been studied. By posing different theories governing the precipitation of the Caspian Sea, next to one another, the pattern was introduced for the torrential rains. Results indicated that the floods were caused by the passage of low pressure systems from the North Caspian Sea. Low pressure cold front has passed over Noushahr on 11 November 2012. The cold front on 12 November 2012, located near the center of Iran, at 35 latitude. With the influx of cold air behind the cold front caused floods in Noushahr city. Cold advection over the sea caused too much moisture absorption by the air. The results also showed that the ridge of high pressure that immigrated from the north Mediterranean had important role in the passage of the cold front is Noushahr city. The ridge is moving cold front to lower latitude finally passes through the north of Iran. The cause of ridge formation was cold air advection on the Caspian Sea. Manuscript profile -

In this research, precipitation and temperature data of southern coastal region of Caspian Sea are examined for 8 synoptic stations in 1977-2009 period. NAO index data are also received from cpc.noaa.gov website. Precipitation and temperature data were examined with their corresponding NAO indices data by correlation test in monthly and yearly time scales. Furthermore, we found that in this region, when NAO index increases, precipitation will increase and temperature will decrease and vice versa. During recent years, NAO index shows negative trend, so we expect decrease of precipitation and increase of temperature in the region. Manuscript profile -

As technological advances provide more opportunities to exploit the natural resources of the oceans, so do threats to biodiversity. Due to the importance of marine biodiversity in areas outside the national jurisdiction and the increasing use of its resources, the international community's concern for the protection of biodiversity in these areas has increased. Gaps in the legal system of maritime areas outside national jurisdiction double the need for effective action to protect the marine environment in these areas.Method: This research has been conducted in terms of practical purpose and in terms of gathering information by documentary method and through the study of valid laws and sources, and the obtained information has been analyzed in a descriptive-analytical manner.Findings and Conclusions: In order to protect this marine environment, there is a need for the adoption of rules and regulations at the international level, which should be respected by the subjects of international law, because despite the multilateral agreements, conventions and agreements, there is still a binding mechanism. Regarding the protection of the environment, there are no high seas, therefore, given the current commitments of governments in the field of biodiversity protection in the high seas, the need for the adoption of a binding document is felt more than ever.

Our findings show that such relation is weak because of mismatching between jobs and education field basicly. This matter leads us to a reality which means omission of this inefficiency source can enhands the labor productivity and increase economic growth. Other results confirm that high education labor force has positive effects than low level education (primary and high school) on different sectors value added. So, authorities should consider more on higher education labor force in their planning and polices. Manuscript profile -

For this purpose, the 5-minute data of Tehran Stock Exchange was used in the period of 2021-2022. Based on the results of the research, it was determined that the variable trend of stock exchange returns in non-linear mode (separation of period length into high and low regimes) is preferable to linear mode, and when the volatility of stock trading is small, the average return of the stock market changes, but the variance of the return changes. The stock market has no significant effect. Also, the results show the asymmetric effects of the effect of stock trading on the changes in stock exchange returns in the boom regime, and the fluctuations of stock trading in the average and high variance regime, in the state of increasing and decreasing stock trading, will have a different effect on the changes in stock exchange returns, and generally its positive effect It is smaller than its negative effects. As a result, it is suggested that the policy makers in the implementation of policies related to the capital market should be proportional to the regime in which the capital market is located, different policies and even if the policies are the same, the intensity of their implementation should be proportional to the characteristics of that regime in each regime.

Therefore, in order to maintain the stability of the car in swing states, the suspension system plays an essential role. Therefore, the active suspension system is used to replace the conventional passive suspension system, to improve comfort and smoothness. To reduce the displacement of the spring mass in the active vehicle suspension system, a high-order sliding mode controller is proposed in this paper. Uncertainty of system parameters, nonlinear characteristic of damping and spring, load changes and unknown path disturbance are estimated by disturbance observer. The controller only needs the information of the spring mass state variables and therefore does not need separate sensors to measure the suspension mass state variables. Particle swarm optimization algorithm has been used to determine the control parameters. The efficiency of the proposed method has been shown using simulation in MATLAB software and the results have been compared with the passive suspension system. Manuscript profile -

In this study, an attempt was made to explain the optimal model for estimating returns and risk in cases where there is a financial crisis and the distribution of return on assets does not follow the normal distribution.For this purpose, we use CAPM with independent and identically asymmetric power distribution (CAPM-IIAPD) and CAPM with independent identically saymmetric exponential power distribution with two tail parameters (CAPM-IAEPD) instead of traditional CAPM. When the assumption of normality is violated, higher moments are used to optimize the model. In the next step, using Polynomial Goal Programming, we calculate optimal portfolios with third and fourth moments.The time horizon of the research from 2011 to 2018 and the statistical population has been all the companies of Tehran Stock Exchange, among which 30 companies have been selected.The results show that CAPM-IIAPD Model is the best model among three models and the adjusted return on risk in optimized models with thirs and fourth moemnts in generalized CAPM models is significantly different from the traditional model and has a better performance.

The first aim of the present article is to get acquainted with the decision-making structure in higher education curriculum design and also to find out whether it is better to centralize or decentralize by searching and reviewing articles from the most famous databases such as irandoc, cilivica, Jahad Daneshgahi database (SID), magiran, noormagz, Google, etc. The author introduces centralized and decentralized systems and examines their advantages and disadvantages in higher education planning and in the history of higher education in Iran and its developments in different periods, levels of decentralization of the curriculum, the position of participation of faculty members and important factors as well as barriers to their participation in the program development process. Finally, while expressing the challenges and solutions of decentralized planning, it has been concluded that complete transfer of decision-making power will not be a good solution to meet the existing needs, but a combination of decentralized and semi-centralized status for higher education in Iran can be very useful and effective.

The population consisted of 483 principals and teachers of Chamestan region. Following Morgan’s Table, a sample of 230 individuals was formed via simple random sampling. For measuring both self-efficacy and effectiveness a researcher-made questionnaire (Shalikar, 1999) with internal consistency of 0.77 using Cronbach’s alpha was employed. To analyze the data, in addition to descriptive statistics such as frequency, percentage, mean, mode and median, inferential statistics including Pearson correlation was utilized. One of the most important findings of the study was that there is a significant and positive correlation between self-efficacy, self-belief, self-regulation, self-measurement and principals’ effectiveness. However, components of self-leadership had no significant association with effectiveness in either level. Also, self-excitement had no significant correlation with effectiveness in high school.

The aime of this experimental study was to determine the effects of eight weeks of submaximal running and high-fat diet on IL-6 gene expression levels in the muscle tissue of an animal model. At the end of the two-week period of keeping under controlled conditions, 40 two-month-old male rats were randomly divided into four equal groups of control, high-fat diet, submaximal running, and a combination of high-fat diet and submaximal running. The training groups participated in the aerobic running protocol on the treadmill for five days a week for eight weeks. The polymerase chain reaction method was used to determine the levels of IL-6 gene expression in muscle tissue. One-way analysis of variance was used to determine between-group differences. The effects of high-fat diet and running with submaximal intensity on IL-6 gene expression in muscle tissue are significant. The consumption of high-fat food causes adverse changes in the expression of IL-6 gene, but eight weeks of running with sub-maximal intensity moderates the adverse effects of high-fat diet and creates favorable changes in the expression of IL-6 gene and body weight.

Stellite 6 and NiCrBSi powders were deposited on the substrate by HVOF and Stellate 6 wire were cladded by GTAW. Scanning electron microscopy with energy dispersive spectroscopy and optical microscopy, pins on disk wear machine, macro and micro hardness meter were used to analyze the coatings. Results showed that the hardness and wear resistance of thermal spray coating were higher than cladding coating. At high temperature, the results of wear test show, that the NiCrBSi coating has the better wear resistance rather than satellite 6 coating. This behavior of NiCrBSi coating attributed to silicate and boride particles in this coating. On the other hand, the thermal spray satellite 6 coating show the very low friction coefficient due to chromium oxide formed on the surface of coatings. Manuscript profile -

For this aim, five different levels are considered for four effective parameters (Fuel injection rate, oxygen injection rate, powder injection rate and spray distance) on HVOF process by response surface method (RSM) and minimum porosity and minimum oxidation layer thickness are considered as the responses. To investigate the microstructure of coatings, Thermal Grown Oxide (TGO) thickness and porosity, a Scanning Electron Microscopy (SEM) and image analysis method are applied. Oxidation test has done at1100ºC for 50 hours on coated samples. Results show that (oxygen injection rate and powder injection rate), (fuel injection rate and powder injection rate), (powder injection rate and spray distance) have a reaction on each other in the TGO thickness value. Also, (oxygen injection rate and powderinjectionrate), (fuel injection rate and powder injection rate) have a little reaction on the porosity against the other parameters which haven’t any effect on it. Investigation of the coated sample with optimized parameters reveals that porosity of the coating is about 0.5% and TGO thickness is about 5.3 micrometer. Manuscript profile -

In this research, a sheet of 6061 aluminum alloy was welded by a Nd:YAG laser machine. For the first time, the diameter of the dendritic arm spacing in the aluminum laser weld was measured and the results were compared with the solidification models. Contrary to the prediction of hot crack models, increasing the dendritic arm spacing, decreasing the solidification rate, and the reduction of the strain rate did not reduce hot cracking. However, based on the pre-existing models, preheating should reduce hot cracks, but inversely increases the amount of cracks. The images of high speed cameras and the assessment of crack surface by a field emission scanning electron microscopy showed that in pulsed laser welding, hot cracks will be created in three steps: 1) initiation 2) the first step of propagation 3) the second step of propagation. Propagation in the second step will occur in the newly solidified weak grain boundary of the weld metal. What is finally seen as a crack in the weld seam is the solidification and high temperature cracks and therefore, the models that are considered for continuous fusion welding are required to be modified based on the conditions of the pulsed solidification and melting and the fracture of weak grain boundaries after solidification should also be taken into account.

In order to produce composite samples, the primary powders were milled and blended in planetary ball mill apparatus with rotational speed of 200rpm and then processed using hot pressing (70ᵒC and 70MPa), cold isostatic press (200MPa), Pyrolysis (1000ᵒC) and sintering (2150ᵒC). The values of relative density and porosity of samples were measured to evaluate the effect of presence of micro-sized SiC and SiC nano particles simultaneously on the pressureless sintering behavior of ZrB2-SiC. In order to compare the microstructure and mechanical properties of samples Scanning Electron microscopy (SEM), equipped with EDS spectroscopy, XRD analysis, hardness and toughness tests were used. The results show that as the volume percentage of nano SiC decreases to 15 vol.%, the hardness, toughness, relative density and shrinkage initially increase and then decrease. Manuscript profile -

Due to the uncompleted reactions such as solvent evaporation and pyrolysis of the precursor, achieving coatings with controlled properties at a satisfactory precipitation rate remains an important challenge in these processes that needs to precise control of spray parameters. In this study, in order to investigate the effect of Solution precursor high velocity flame spraying parameters such as fuel and oxygen content, spraying distance and solution injection rate, single-scan spraying test was performed on glass substrates. The morphology of the formed splats and their structural characteristics were investigated using Scanning Electron Microscope (SEM). Structural comparison in the single-scan spraying test performed in two ratios of fuel to oxygen, showed that in the flame parameter with oxygen pressure of 6 bar and fuel 3 bar at the injection rate of Solution precursor 20 cm3/min and spray distance of 5 cm was selected as the optimal parameter. In this parameter, due to the low injection rate of the solution and higher heat transfer per drop of the solution precursor and completion of processes that resulting in melting and crystallization, the number of splats increased. Also, evaluation of single-scan spraying in the flame with oxygen pressure of 8 bar and fuel bar of 4 bar and spray distance of 5 cm showed that the injection rate of 40 cm3/min solution precursor would be more appropriate due to increasing the number of fine splats and improving coating efficiency.

The effect of graphite nano-flake on the densification behavior of the mentioned composites were investigated. Spark plasma sintering was carried out at a temperature of 1900 °C for a dwell time of 7 min under an applied pressure of 40 MPa. A fully dense ZrB2-SiC composite (with relative density of 100.6%) was obtained by the addition of 5 wt% nano-graphite. Elimination of oxide impurities through the chemical reactions with graphite as well as formation of sub-micron phases caused to an enhancement in the densification. In addition, the in-situ formed ZrC phase was one of the reasons behind the increasing of relative density.

Phase transformations via solidification and solid state reactions are discussed. Observations indicated that the microstructure of IN738/MBF-30/TiAl joint consist of four different zones; isothermal solidification zone in both sides, athermally solidified zone in the bond center, diffusion affected zone in the IN738 side and reaction layer in the TiAl side. γ-Ni solid solution phase in ISZ of the IN738 side and binary isostructural solid solutions in ISZ of the TiAl side were formed during holding time at bonding temperature. Ni-Cr borides have been formed due to binary eutectics associated with γ-Ni solid solution in the ASZ during cooling. Cr-Mo borides and Ni-rich boride with different morphologies were precipitated in the DAZ. Ni element from MBF-30 molten interlayer reacted with γ-TiAl base, leading to the formation of the reaction layer containing single phase δ-Ti2Ni and triple phase τ2-Al2TiNi+τ4-AlNi2Ti+β1-NiAl layers adjacent to TiAl substrate. Microhardness evaluation of different zones indicated that some high hardness phases have formed in the bond region and presence of the γ-Ni solid solution in the ASZ cause to decrease the detrimental effects of them.

According to the results, microstructure of the weld metals includes Cr and Nb Carides precipitating along the grain boundaries of austenitic matrix. Weld metal of the sample welded with UTP 3545 Nb filler metal showed denser and more continuous carbides which arises from higher Cr content in this filler metal. According to the XRD analysis of the oxidized weld metals at 1000 ℃ for 96 h, all samples represent an external oxide layer, mostly consist of Cr oxide and an internal oxide layer, mostly composed of Si oxide. Weld metal of the sample welded with UTP 2535 filler metal showed the highest weight gain (4.3 mg/cm2) and oxide thickness (20 μm). For the weld metal of the other sample, these values were 3.6 mg/cm2 and 11 μm, respectively. It can be attributed to the higher Cr and Si in the UTP 3545 Nb filler metal. The first element results in a resistant, continuous, and defect free external oxide on the surface, and the latter one leads to formation of a resistant internal oxide, both strongly effective in improving the oxidation resistance of the weld zone.

The applied powers of 1200 and 1450 W, the scanning speeds of 1.6 to 3 mm.s-1 and working distances of 55,, 70 and 75 mm were applied as test parameters. Microstructure and phase analysis and microhardness measurement were studied by optical microscopy, electron microscopy, X-ray diffraction and microhardness testing methods, respectively. The microstructure and phase analysis showed that the hardening process led to the formation of martensite and retained austenite dual-phase structure. The use of laser, created all three states of surface hardening, surface melting and non-hardening. The best result in terms of depth and width of hardening was obtained for samples with energy density of 208-250 J/mm2. The calculation of retained austenite phase percentage and heat input, indicated that an increase in the heat input raised the residual austenite percentage, so that for the sample with maximum heat input, the retained austenite phase percentage was calculated to be approximately 37%. Also, for the sample with the highest heat input (906/J/mm2), the lowest hardness was obtained (653 Vickers) and the sample with lower heat input (725 J/mm2) was owned the highest hardness (760 Vickers). Investigations of the values of hardening efficiency showed that the hardening conditions are not improved only by increasing the laser energy density, but to obtain highest hardness and appropriate microstructure, the optimum amount of power and scanning speed is needed.

The microstructure and phase composition of the coatings were investigated by SEM and XRD before and after the oxidation test. The porosity (volume percentage) and surface roughness (micrometer) were measured for HVOF coating as 0.6 and 4.4, and for LPPS coating as 2 and 6.62, respectively. The HVOF coating consisted of γ-CoNiCr and β-(Co,Ni)Al, while the LPPS coating included a single phase γ-CoNiCr. The disappearance of the β phase in the LPPS coating after spraying was due to dissolution in the plasma jet and its non-recovery in the conditions of rapid quenching and non-equilibrium solidification. This phase was recovered after heat treatment. The microstructure of the LPPS coating had much less oxide than the HVOF coating due to depositing at low oxygen pressure in the vacuum chamber. After 200 hours of oxidation test, the amount of β phase (as an oxidation resistance criterion) was completely consumed in the LPPS coating, while the HVOF coating contained the retained β deposits. The average thickness of TGO layer for HVOF and LPPS coatings was 5.2 and 7.1 μm, respectively. The dispersed oxides in the microstructure, lower roughness and denser structure of HVOF coating were reasons for the higher oxidation resistance of HVOF coating than LPPS. Manuscript profile -

Animal models are a valuable tool in these studies and could be developed using a simple and cost effective diet in susceptible strains. Adult NMRI mice weighing 25andplusmn;4 g were fed by a high fat diet for six weeks (E group) in comparison with a control group(C) receiving standard chow. Weekly measurements of body weight were performed. Animals were sacrificed after six weeks, and abdominal fat amount, fat liver accumulation, and LDL-C, HDL-C, cholesterol and triglyceride were measured. Histological studies were done on kidney, liver and testis. Body weight of E group increased up to about 50% (1.25-fold more than C group), their abdominal fat amount showed a two-fold increase compared with the C group(pandlt;0.001), and morphologic differences were observed in liver tissue relative to fat accumulation. Of biochemical factors, only triglyceride levels showed statistically significant increase in the E group (pandlt;0.05). Microscopic assessment of kidney, liver and testis samples, regarding to cells size and number showed no significant differences between C and E groups. This method is proposed as a mean to simulate an early stage of obesity. Manuscript profile -

Exercises and diet modification can affect oxidant and antioxidant factors. The aim of this study was to investigate the effect of high-intensity interval training (HIIT) and high-protein diet (HPD) on total oxidant status (TOS), total antioxidant capacity (TAC) and the ratio of TAC to TOS in the heart tissue of obese male rats. Forty 12-week-old obese male rats (Lee index above 310) were divided into five groups of eight including HIIT (5-12 intervals of 30 seconds with an intensity of 90% VO2max, 5 sessions per week, 10 weeks), HPD (about 57.5% of total calories from protein), HIIT+HPD, obese control-1 (OC-1) and obese control-2 (OC-2) and eight non-obese mice were also divided into the non-obese control (NC) group. became After 48 hours from the last intervention session, heart tissue was removed to measure TAC and TOS levels. Data were analyzed using one-way analysis of variance, post hoc Tukey, Kruskal-Wallis and Mann-Whitney tests at a significance level of p ≤ 0.05. The results showed that the TAC level of heart tissue in the HIIT, HPD, HIIT+HPD groups was significantly higher than in the OC-1 group. On the other hand, the TOS level of heart tissue was significantly lower in the HIIT and HIIT+HPD groups than in the HPD and OC-2 groups. Also, the ratio of TAC to TOS was significantly higher in the HIIT and HIIT+HPD groups compared to the OC-2 group. According to the results, a combination of HIIT and HPD improves TAC and TOS of heart tissue. It seems that HIIT together with HPD strengthens the antioxidant system and reduces oxidative stress in obesity conditions. Manuscript profile -

Introduction: This study aimed to investigate the comparison of a different orders of concurrent training on plasma IL-6 levels, insulin resistance index (HOMA) and anthropometric characteristics of an elderly male. Forty women with 55-70-year-old which having no particular illnesses were divided into 4 groups: endurance-resistance, (n = 9), resistance-endurance (n = 10), interval resistance-endurance (n = 12) training, and control group (n = 9) randomly. Height, weight, BMI, WHR, and serum levels of myonectine glucose and insulin were measured and recorded before and after performing protocol. Experimental groups participated in concurrent training for 8 weeks, 3 sessions every week, 60 minutes in every session. A univariate (covariance) test was used for analyzing the data. A significant increase of vaspin (p < /em> = 0.009) and the significant decrease of glucose (p < /em> = 0.001) and HOMA index (p < /em> = 0.028) was observed in the experimental groups compared to control, no significant difference among experimental groups. There was not any significant difference among groups in insulin levels (p < /em> = 0.37). Older males can take advantage of the concurrent training with any orders of them. Manuscript profile -

This study aimed to determine the effects of six weeks of aerobic exercise, consumption of cinnamon extract and high fat diet on the expression of 1 beta interleukin gene in liver tissue of male rats fed a high fat diet using two-month-old male Wistar rats. Fifty two-month-old male rats were divided into five control groups: high-fat diet, cinnamon extract, and high-fat diet, aerobic training and high-fat diet, and aerobic training and cinnamon extract and high-fat diet after two weeks of control. Cinnamon extract at a rate of 200 mg per kg of body weight and emulsion of high-fat food in excess of water and normal diet of rodents daily at a rate of 1.5 mg per kg of body weight for six weeks by gavage. The training group participated in an aerobic exercise program on a treadmill five days a week for six weeks. The mean of research variables among groups (except the control group) was compared with one-way variance analysis and Bonferroni tests to determine the differences among groups. The mean of research variables between each group was compared with the control group to determine the differences within the group by one-sample t-test at the significant level of p 05 0.05. There was a significant difference between body weight and liver tissue weight in the post-test between all groups. The difference among the mean variables of one beta interleukin in the liver tissue of male rats fed a high-fat diet after six weeks of aerobic exercise, consumption of cinnamon extract, and high-fat diet was significant. Therefore, it seems that the effects of high fat diet, high fat diet and aerobic exercise, high fat diet, and cinnamon and high-fat diet, and aerobic exercise and cinnamon on the interleukin variable of one beta in liver tissue are significant and significant.

Six MoreThe number of training sessions is an important factor in exercise training. Therefore, this study was aimed at investigating the effect of eight weeks of low and high volume HIIT training on lactate response and some performance indicators of Canadian canoe rowers. Sixteen female rowers invited to the Canadian Canoe National Team Camp were randomly divided into two groups: low frequency interval training and high frequency interval training. Rowing ergometer and respiratory gas analyzer were used and at the same time, physiological variables of aerobic function including maximum oxygen consumption (VO2max), minimum speed to reach maximum oxygen consumption (vVo2max) and exhaustion time (Tmax) were measured. Intense intermittent training was performed in both groups in the form of 6 one-minute rowing sessions with 100% vVo2max and with an increase of two rounds per week. The difference was that the low-frequency group practiced 3 sessions per week and the high-frequency group practiced 6 sessions per week. Exercises were performed for eight weeks. Data were analyzed by paired t-test and independent t-test. Significance between variables was considered at the level of P≤0.05. The results showed a significant difference in lactate, VO2max, vVo2max and Tmax between pre-test and post-test of both high-volume periodic training and low-volume periodic training. However, no significant difference was observed in the post-test values between the two groups in any of the variables (P≤0.05). Due to the lack of significant differences between the two groups, the combination of these two methods at different times of a Canadian canoeing season seems to be helpful in preparing athletes.

Obesity can be caused by sedentary lifestyle and a high-cholesterol diet. This condition increases oxidative stress and decreases the activity of oxidative enzymes, resulting in many complications, including cardiovascular disorders. Aerobic exercise and avoidance of high-fat diets are used as a non-pharmacological intervention to increase antioxidant capacity; however, the exact mechanisms of this on the cardiovascular system have not yet been fully identified. The aim of this study was to evaluate the effect of 12 weeks of aerobic exercise on cardiac antioxidant enzymes in mice fed high cholesterol diet. Thirty-two laboratory Wistar rats (191.2 ± 19 g), age 6-8 weeks were randomly assigned to four groups after the hypercholesterolemia induction of half of the rats (adding 1% cholesterol to the food of the rats and sampling the tails of the rats). These four groups comprised of the aerobic exercise-normal nutrition group (n=8), hypercholesterolemic group (n=8), aerobic exercise- hypercholesterolemic group (n=8) and normal nutrition group (n=8). Each endurance exercise training session was held five days a week for 12 weeks. Twenty-four hours after the last training session, the rats were killed and the cardiomyocytes were removed. Moreover, the activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) enzymes was evaluated by specific kits. The results showed that increasing blood cholesterol had a statistically significant effect on reducing SOD, CAT, and GPX in heart tissue (p=0.001). Furthermore, it was found that aerobic exercise significantly increases the activity of antioxidant enzymes in cardiomyocytes (p=0.001). The highest decrease in the level of antioxidant enzymes was related to the hypercholesterolemic group and the highest increase was related to the aerobic exercise-normal nutrition group. Cholesterol-rich diets reduce the activity of antioxidants in the heart. Although aerobic exercise increases the heart’s antioxidant activity, it seems that avoiding a high-cholesterol diet can play a more effective role. Manuscript profile -

For this purpose, 24 Zell male lambs with an avrage age of about 5 months and an avrage weight of 25.4±0.50 were used for 90 days. The experimental treatments included 1- control group (no supplement), 2- treatment containing 2 g of A-Max prebiotic supplement, 3- treatment containing 4 g of Biomin IMBO synbiotic supplement, and 4- treatment containing 6 g of Bioherbal phytobiotic supplement per head of lamb per day. The growth performance results showed that there was a significant difference between the experimental treatments in the fattening weight, dry matter intake, daily weight gain and feed conversion ratio (p < 0.05). The highest weight at the end of the fattening period, dry matter intake and daily weight gain were observed in the treatment of 4 g of synbiotic supplement. The treatment with 6 g of phytobiotic supplement had the lowest feed conversion ratio. The highest apparent digestibility of dry matter, NDF and ADF was observed in the treatment of 4 g of synbiotic supplement (p < 0.05). The results of some blood serum parameters showed that there was a significant difference in the concentration of glucose, cholesterol, triglyceride and blood urea nitrogen between the experimental treatments (p < 0.05). The highest concentration of glucose was in the treatment of 4 g of synbiotic supplement, the lowest concentration of cholesterol was in the treatment of 6 g of phytobiotic supplement. Blood urea nitrogen had the lowest concentration in the treatment of 4 g of synbiotic supplement. The treatment with 4 g of synbiotic supplement had the highest hot carcass weight, hot carcass percentage, cold carcass weight, cold carcass percentage, thigh percentage and shoulder percentage (p < 0.05). The present research showed that the addition of 4 g of synbiotic supplement in the diet improved the growth performance, valuable parts of the carcass and the apparent digestibility of nutrients in fattening lambs.

Therefore, the aim of the present study was to evaluate the effect of eight weeks of high-intensity interval training on GPR120 and AMPK proteins in the cardiac tissue of mice with type 2 diabetes. In an experimental study, 40 three-month-old adult male Wistar rats with an average weight (250-300 g) were randomly divided into four groups of 10 series including: healthy control (C: intraperitoneal injection of saline), healthy training (T: running at 85-90 % of maximum speed in 6 to 12 bouts in two-minute periods; 5 days per week for eight weeks), diabetic control (D: diabetic on a high-fat diet with intraperitoneal injection of streptozotocin) and trained diabetics (D+T: diabetic with training) were divided. A method based on Western blotting was used to determine changes in the expression profile of GPR120 and AMPK proteins in the heart muscle tissue (left ventricle) of rats. The two-way analysis of variance and Bonferroni post hoc test were used to analyze the data. Induction of diabetes (D) significantly reduced GPR120 and AMPK proteins (p ≤ 0.05). While HIIT training apply in healthy group (T) increased 81% and 47% in GPR120 and AMPK compared to diabetic control group (D) respectively (p = 0.001). Also, training intervention has the ability to prevent a decrease in both of proteins in the trained diabetic group (D+T) compared to the diabetic group (D) (p = 0.023). Based on the findings of this study, it can be stated that eight weeks of high-intensity interval training (HIIT) is a preventive strategy against reducing the activity of GPR120 and AMPK proteins involved in the reverse cholesterol transmission during type 2 diabetes.

This study aims at investigating the molecular changes in Human Dermal Fibroblasts (HDFs) in a high-glucose state and improving the effect of N-Acetyl-L-Cysteine (NAC) and gene expression of oxidative genes Super-Oxide Dismutase (SOD) and Heme Oxygenase1 (HO1). HDFs were cultured in 5.5, 25, 50, and 75 mM glucose concentrations for 72 hours. Cell proliferation was examined via 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assays. Oxidative stress markers of SOD and HO1 were quantified with real-time Polymerase Chain Reaction (PCR). The antioxidant effect of NAC on 1 mM was examined to evaluate oxidative markers in the glucose effects on the HDFs. The MTT assay revealed a decline in cell viability in 50 and 75 mM glucose concentrations. mRNA level of SOD and HO1 was upregulated. The antioxidant addition of NAC reduced the inhibitory effect of the high-glucose state on the proliferation of the HDFs. A high-glucose state impairs the in vitro proliferation and migration of HDFs and may, therefore, induce increased oxidative stress and cellular dysfunction. The antioxidant effect of NAC ameliorates the damaging impact of a high-glucose state. Manuscript profile -

On MoreUltra high molecular weight polyethylene (UHMWPE) has been used as the material of choice in joint replacement prosthesis as an articular component for several years. Despite its distinct physical and chemical characteristics, the lifespan of this polymer is limited. One approach to increase the lifespan and mechanical properties is the use of multi-walled carbon nanotubes (MWCNT). Multi-walled carbon nanotubes are promising candidates for use as a filler phase in polymers due to their excellent mechanical properties and excellent surface-to-volume ratio. In this research, the addition of 0.1% by weight of multi-walled carbon nanotubes functionalized with carboxyl groups was investigated on the mechanical properties and biocompatibility of the UHMWPE base matrix and its comparison with the pure UHMWPE sample. Fourier transform infrared spectroscopy (FTIR) confirmed the presence of characteristic peaks of UHMWPE and carbon nanoparticle in the matrix. X-ray diffraction (XRD) showed an increase in the intensity of the characteristic peaks of the composite compared to the pure sample. The differential scanning calorimetry test (DSC) showed an increase of about 10% in the crystallinity of the composite containing carbon nanotubes (PE/MWCNT). The dynamic mechanical thermal analysis (DMTA) showed an increase of about 22% in the storage modulus compared to the control sample, and finally, the cell viability through the cell culture test in the PE/MWCNT composite showed a 15 % increase in cell viability. According to mechanical and biocompatibility results, the composite sample can perform better in terms of mechanical loads in bearing surfaces compared to pure UHMWPE. Manuscript profile -

To overcome the limitations transposons, which are mobile genetic elements and have the ability to cut and insert target fragments in certain regions of the genome with the “Cut and Paste” mechanism, are effective. This research aims to evaluate the effect of the PiggyBac transposon vector on the expression level of recombinant Erythropoietin (rEPO) protein and to find a cell line with high expression. First the optimized rEPO sequence based on CHO codon performance was cloned into the pOptiVECTM plasmid. To create the second expression vector, the EPO-IRES-DHFR fragment was inserted into the PB513B-1 plasmid, and then the homogenization steps in both vectors were confirmed using Colony PCR reaction, enzyme digestion, and Sanger sequencing. In order to create a stable cell line, both vectors were separately transfected into CHO DG44 cells and then screened. After confirming the insertion of the vectors into the genome of the target cell, the level of erythropoietin gene expression at the transcript and protein level was checked using qRT-PCR and western blotting tests, respectively, in two cell lines. The Real-Time PCR data indicate a 188-fold increase in erythropoietin gene transcript in the PB513B-1-EPO cell line compared to pOptiVEC-EPO. Additionally, the western blotting test's result confirmed the correct synthesis and secretion of this protein. Analysis of findings in this research revealed that the transposon element significantly increased the expression of the desired gene at the transcriptional level and had could create a cell line with high expression of the target protein.

The purpose of this study was comparison of the influence of 12-week high-intensity interval training (HIIT) and moderate intensity continuous training (MICT) on PGC-1a and Tfam mitochondrial proteins expression in gastrocnemius muscle of elderly rats. In this study 45 elderly 22 months old Wistar rats (weighing 325-375g) were randomly divided into three groups: HIIT, MICT, and the control group. The exercise in the HIIT group was started with 20 minutes (2 minutes at 85-90% VO2max intensity and 2 minutes of recovery period at 45-50% VO2max intensity) in the first week and then reached to 48 minutes in the 12th week. The training program in the MICT group was begun with 20 minutes (at 65-70% VO2max intensity) and reached to 48 minutes in the 12th week. The expression levels of PGC-1α and Tfam proteins in gastrocnemius muscles were measured by Western blot method. One-way ANOVA was used to analyze the data. The PGC-1α expression was significantly increased in the HIIT (P< 0.001) and MICT (P<0.01) groups compared to the control group. Also, PGC-1α levels were significantly increased in the HIIT group compared to the MICT group (P<0.05). Tfam expression was significantly increased in the HIIT (P<0.01) and MICT (P<0.05) groups compared to the control group. HIIT resulted in a greater increase in PGC-1α and Tfam expressions in the gastrocnemius muscle of elderly rats compared to MICT. Manuscript profile -

Modifying the lifestyle through sports activities and herbal medicines is one of the solutions to combat this problem. The purpose of this study was to evaluate the effect of an 8-week cinnamon consumption with and without high-intensity interval training on blood lipid profiles in high school-aged overweight girls.Methods: In this semi-experimental study with a pre-test and post-test design, 36 overweight women aged 15-18 years were randomly assigned to one of the 3 groups: intense interval training (n=12), cinnamon supplementation (n=12) and intense interval training+cinnamon (n=12). The intense interval training program was conducted three times a week for 8 weeks in the two intervention groups. Each session, lasting 30-35 minutes, involved high-intensity exercises at 90-95% of peak oxygen consumption. Diet groups received cinnamon supplements at the rate of 6 grams/day for a period of 8 weeks. Body measurements (weight, body mass index) and serum levels of blood fats (cholesterol, triglyceride, high-density lipoprotein, low-density lipoprotein) were measured before and after the study. The data were analyzed using the dependent t-test and analysis of covariance at a level less than 0.05.Results: After 8 weeks of intervention, a significant decrease in body weight and body mass index and a significant increase in HDL cholesterol were observed in the intense interval training and intense interval training + cinnamon groups compared to the cinnamon alone group (p≤0.05). However, Bonferroni's follow-up test did not show significant differences in cholesterol, triglyceride and low-density lipoprotein levels between the groups (p≥0.05).Conclusion: High-intensity intermittent exercise with cinnamon consumption can reduce body composition and some blood lipids more effectively than cinnamon supplementation in overweight high school girls.

The aim of this study was the influence of different ways of backpack carrying on pelvic kinematics during gait among male students.Methods: Twelve boys aged 7–12 years from Yazd participated in this study. Using a three-dimensional motion analysis system, unilateral and bilateral evaluations of walking while carrying backpacks were conducted. The data were processed using MATLAB software. The Shapiro-Wilk test was performed to determine data distribution, and the paired t-test was employed for statistical analysis (p<0.05).Result: According to the research's findings, the two carrying techniques had similar amounts of anterior pelvic tilt. However, the unilateral backpack approach had slightly greater values for this angle. Due to the positioning of the body on the ground and the slower rate of thigh extension, the graph is downward throughout the stance phase of stepping, which comprises approximately the first 60% of the gate cycle. Additionally, the two carrying techniques in this range differ the most from one another. The levels of coordination variability differed by 30 to 40 degrees in various deciles between the two carrying techs. Furthermore, compared to the bilateral carrying approach, the unilateral carrying strategy had substantially higher hip rotation variability.Conclusion: Generally, the results indicated that except for hip-thigh coordination during walking, there are no appreciable differences in the effects of various backpack carrying techniques on the risk factors for hip-thigh injuries. Except for pelvic-thigh coordination during walking, while using various backpack carrying techniques, a significant difference was noticed. Manuscript profile -

In the present study, a systematic and strategic model of knowledge commercialization in higher education centers is designed according to the cultural factor.This research is an applied research in terms of purpose and descriptive survey in terms of method. The data of this research include documents received from keyword searches in reputable scientific databases and conducting interviews. In this research, first, using the content analysis method and its implementation in 2020MAXQDA software and performing open and axial coding, the components were identified and summarized, and then the final framework was formed using selective coding. Then, to check the validity of the model, 24 questionnaires were distributed among the statistical sample and analyzed with SmartPLS software.The findings show that the output of content analysis of 26 components in 5 dimensions (knowledge commercialization process, benefits, environment, resources and organization) was identified and the output of confirmatory factor analysis also showed the approval of 48 final indicators. It had validity and reliability tests and the final model was presented with 5 dimensions and 22 components.The system model presented in this research can study the process of turning ideas into technology and knowledge transfer with respect to cultural factors and use the environment and organization for creating appropriate output and benefits. Based on the presented results, decision makers in universities are advised not to implement the initial raw ideas quickly and instead they have to specify a specific process for presenting and evaluating existing ideas. It is also suggested to pay more attention to the role of cultural values, because the commercialization of knowledge, although considered a material activity, must be based on the right organizational culture and values Manuscript profile -

Looking at the performance of American diplomacy in Iran over the past decades, it can be understood that US is trying to promote American values and lifestyle, to establish a west-oriented middle class, especially in the universities, and also to develop English language as a scientific and communication tool.Accordingly, understanding US experience and practice in the field of academic diplomacy towards a country such as the Islamic Republic of Iran will be important. The main question of the present article is to understand how the US academic diplomacy has attracted academicians, especially the Iranian elites? Our hypothesis is that, using its academic tools as well as educational attractiveness, the country has been able to have the largest educational exchanges around the world, and thus, to disseminate its values to academicians, simultaneously with increasing its soft power. These attractivenesses have led many Iranian scholars to study abroad especially in the United States. Manuscript profile -

The evaluation of cultural policy lacks a local model. The present study was conducted with the aim of designing a model for evaluating cultural policy making in higher education institutions. This study followed with mixed method research (qualitative – quantitative). In qualitative sector, meta-synthesis of research findings (from 2002 t0 2019) was used. Semi-structured interviews with 19 experts selected through purposive sampling were done for purification, verification and validating of indicators. At final, three criteria including; 1) appropriateness in accompany with (2 factors, 5 criteria, 10 indicators); 2) efficiency (3 factors, 7 criteria, 16 indicators); and effectiveness (3 factors, 7 criteria, 16 indicators) were identified as a model for evaluation of cultural policy making in higher education institutions. In quantitative stage, the descriptive – analytical method was used for testing model. The statistical population was including 3163 faculty members of which with using Morgan table, 341 people in relative sample class method for each of three universities (Tehran, Allameh Tabatabai, and Al-Zahra), and 241, 59, 41 people were chosen respectively. A researcher made questionnaire resulted from qualitative section in Likert spectrum was developed for getting needed information. Validity (face, content, construct validity) was used for investigating quality and accuracy of questionnaire. Cronbach Alpha (0/94) was used for measuring reliability. At final, validity and reliability were confirmed. The results of second - order confirmatory factor analysis showed that the eight factors have a sufficient factor load to predict the cultural policy making evaluation model for higher education institutions. In order to test the model and check the data, 313 questionnaires were analyzed. The results of the second-order factor analysis showed that the eight factors have sufficient factor loading to predict the pattern of cultural policy evaluation of higher education institutions. So, 3 standards, along with 8 factors, 19 criteria and 42 indicators can form localized model for evaluation of cultural policy making and gather useful results for identification, amendment, improvement and promotion.

Aim:The purpose of this study was comparison of inguinal hernia surgery results in children with and without high ligation of hernia sac with consideration of conditions and necessity. method:This cross sectional study was done between 1/1384 and 9/1387(shamsi) in pediatric surgery centers of Mashhad (Iran). Amongst 287 children who undergone hernia repair surgery by a single surgeon, 100 patients were return for regular follow-ups. Of these patients, ligation of hernia sac was done on 76 cases. In the rest of patients (24 cases) hernia was repaired without ligation Results: In 1-3 years follow-up there were no recurrences or complications ,which need intervention, in any group. Also there were no complication during surgery such as bulging viscera out of surgical inscision after retraction of missed hernia sac. Conclusion: According to absence of recurrences or complications ,which need intervention, in any groups it can be concluded that when there is no possibility of easy ligation of hernia sac without any damage to cord we can avoid the high ligation of processus vaginalis. Anyway there is need for other studies with more patients to confirm the safety of this recommendation. Manuscript profile -

Since, obesity is also related to imbalance of oxidative- antioxidative system of body; purpose of this study was to investigate the effect of 14 days of resveratrol supplementation on changes in serum levels of ceruloplasmin and malondialdehyde in response to one bout of high intensity exercise in sedentary overweight young men. For this purpose, twenty sedentary overweight young men selected and randomly divided into two groups (experimental and control). Subjects in both experimental and control groups participated in one bout of exhaustive exercise (Bruce Test). Then, subjects in experimental group (supplementation) consumed one capsule of 400-mg resveratrol per day for 14 days. In control group (placebo), subject consumed one capsule of 400-mg lactose per day for 14 days. First blood sample was taken before the study and second one was done immediately after Bruce test. At the fifteenth day and at the end of 14 days of supplementation, subjects in both groups perform the exhaustive exercise again and forth blood sample was taken immediately following their performance. Data analysis was done using repeated measures ANOVA, and paired t-test, and P<0.05 was considered statistically significant. Finding showed 14 days of resveratrol supplementation had significant effect on serum levels of ceruloplasmin in response to one bout of high intensity exercise (P=0.043). It seems that 14 days of resveratrol supplementation has a significant effect on the improvement of function of antioxidant system of body in in sedentary overweight young men. Nevertheless, further research is necessary to understand the mediated mechanism. Manuscript profile -

In order to investigate the effect of crop density and variety in the production of greenhouse cucumber (Cucumis sativus), a factorial experiment was conducted in the form of a basic design of randomized complete blocks in 3 replications during 2016 and 2017. Based on this, single-flowered, double-flowered, medium-flowered and multi-flowered cucumber cultivars were cultivated in different planting densities of 37, 42 and 47 cm. The results of the research showed that the highest production productivity was achieved in the planting density of 42 cm between the plants and the selection of multi-flowered cultivars with a maximum yield of 270 tons per hectare, and the lowest yield was obtained in single-flowered cultivars with a planting density of 37 cm. meter and numerical value of 197 tons per hectare was obtained. Therefore, the main reason for the decrease in cucumber yield in Tehran province was the selection of low-flowering cultivars with inappropriate planting density. Manuscript profile -

948 - High Impedance Fault Detection in Distribution Systems Using a Method Based on Similarity Measurement
Ammar Abduladheem Ahmed Dibes Mohammad Mahdi RezaeiThe electric arc is one of the most intense electrical events.

This phenomenon occurs due to the electric discharge between two conductors or between a conductor and the ground, through the air. When the short-circuit current intensity is high, it can be easily detected by traditional protection equipment. However, when the short-circuit current is low, traditional protection methods cannot detect these faults. Faults that do not generate enough fault current to be detected by conventional protective equipment are called high-impedance faults (HIFs). HIFs can cause serious safety hazards in power distribution systems and damage to equipment due to the risk of arc ignition. This paper presents a new detection scheme for HIFs in electrical distribution systems based on similarity measurement. In this method, based on the waveform of two consecutive half-cycles of the current, an index is extracted that can be used to detect HIFs. The proposed HIF detection algorithm can distinguish these events from other non-fault events with waveforms that may be similar to HIF waveforms. In this paper, four case studies are simulated to verify the proposed HIF detection algorithm. The simulation results demonstrate the acceptable performance of the proposed method in detecting HIFs and distinguishing them from other events. Manuscript profile -

This study evaluates its effect on economic growth in 59 high-income countries from 2004 to 2021, using panel data and quantile methods. Financial inclusion is measured through banking penetration, availability of banking services, and usage of financial services. The results reveal significant differences among countries, generally enjoying favorable macroeconomic conditions, and indicate slight convergence among them. Positive impacts on economic growth were observed from bank and facility penetration, while ATM penetration and financial deepening showed negative effects. Influential factors include capital, inflation rate, unemployment rate, economic openness, life expectancy, and population growth. The impact of financial inclusion is more pronounced in lower-income countries. Expanding financial inclusion through the Internet and mobile banking, especially in less privileged areas, and enhancing microfinance and user-friendly applications, are pivotal for economic growth.

In recent years, vesicular arbuscular mycorrhizal fungi have been used in many plants to deal with dehydration and drought stress. In this regard, an experiment was conducted as split-plot in the form of randomized complete block design with 3 replications in the Yasuj region at years 2015 and 2016. Water stress was considered as the main factor in the form of irrigation after 30, 60, 90, 120 and 150 mm of evaporation from the evaporation pan class A and mycorrhizal fungus was considered as a secondary factor in the form of no application, application of Glomus mosseae and application of Glomus intraradices. The results showed that the interaction of irrigation and mycorrhizal fungi on flower phosphorus, flower yield, biological yield and water use efficiency of Borage was significant. In irrigation levels after 60, 90, 120 and 150 mm of water evaporation from the evaporation pan, the use of mycorrhizal fungi Glomus mosseae and Glomus intraradices compared to the absence of fungi respectively increased the yield of plant flowers (30.04% and 27.35 %), (90.2% and 90.98%), (93.21% and 94.1%) and (81.73% and 78.86%), also, at these levels of irrigation, biological yield and water use efficiency of Borage flower achieved a significant increase in the presence of mycorrhizal fungus, compared to the absence of mycorrhizal fungus application. Application of both strains of mycorrhizal fungus Glomus mosseae and Glomus intraradices in irrigation levels after 90, 120 and 150 mm of water evaporation from the evaporation pan compared to no application of mycorrhizal fungus, respectively, resulted in a significant increase in the harvest index of Borage flower (44.55% and 43.36%), (13.21% and 15.96%) and (5.6% and 5.41%) and flower phosphorus (44.69% and 20.45%), (150% and 125%) and ( 267.74% and 235.48%). Mycorrhizal fungus was able to moderate the negative effects of drought stress and increase the above-mentioned traits in those irrigation levels, and based on the results of this study, irrigation treatment after 90 mm of water evaporation from the evaporation pan + the use of Glomus mosseae mycorrhizal fungi is recommended.

Exercises can be a key factor in reversing or increasing this complication; Therefore, the aim of this research is the effect of high-intensity interval training (HIIT) on the content of autophagy proteins (BECLIN1 and AMBRA1) in the skeletal muscle of aged rats. Materials and Methods: The current research is of experimental-fundamental type, in which 12, 20-month-old male Sprague-Dawley rats with an average weight of 400±30 grams were randomly divided into 2 groups: 1) control (6 head) and 2) HIIT (6 head). The HIIT training program consisted of 8 weeks and 3 sessions per week with an intensity of 85-90% of VO2max. After 48 hours after the last training session, the EDL muscle tissue of the rats was removed. Data analysis Data were analysed through independent t-test in SPSS version 27 and GraphPad Prism version 2.2.10 software. The significance level was less than p≥0.05. Results: Eight weeks of HIIT training increased BECLIN1 protein intracellular content (P=0.0001) and decreased AMBRA1 protein intracellular content (P=0.0001) in EDL muscle of aged rats. Conclusion: Considering the conflicting results in the content of BECLIN1 and AMBRA1 proteins, it suggests that the adaptive responses of HIIT differ in the regulation of the autophagy pathway.

In terms of methodology, the current research was conducted using the qualitative method and using thematic analysis with MAXQDA software. The participants of this research, in the library section, were upstream documents and key documents of higher education, and in the field section, faculty members, managers and relevant officials. People were selected by targeted sampling with the criteria of at least fifteen years of teaching, research and management experience in different academic courses. Sampling was done with the participation of 30 experts. The data collection tool consisted of two sections, review and exploration of upstream documents and higher education documents in the library section and semi-structured interview in the field section. The semi-structured interview with the participants continued until the theoretical saturation stage. Data analysis was done based on thematic analysis. The research findings showed that the organizational well-being model for higher education includes 32 components and 5dimensions (individual well-being, occupational well-being, managerial well-being, process well-being, environmental well-being). In addition, the participants mostly mentioned the dimensions of individual well-being and occupational well-being, but in the upstream documents, the dimensions of managerial well-being, well-being of processes, and environmental well-being were discussed more. With a systematic look at the current research, we can see that the concept of organizational well-being has an important and effective role in improving the work process, and individual differences, occupational characteristics and organizational ethics variables, etc are antecedents of well-being.Therefore, the design of the organizational welfare model in higher education issues is needed to achieve a coherent and structured model.

Current study investigated the role of attachment and family functions in prediction of emotion regulation in adolescents. A sample of adolescents between the age of 14 to 17, selected based on multi-level cluster sampling, completed a battery of questionnaires including family function assessment, inventory of parent and peer attachment and children and adolescent’s emotion regulation checklist. Data were analyzed using SPSS software. The results of this study showed that the overall function of the family was most important in predicting emotional stability, self-awareness in expressing emotions, emotional expressiveness in suitable situations, emotional flexibility and control and management of emotions. Other family functions’ subscales including behavioral and communication control also played an important role in emotional expressiveness in suitable situations. However, attachment to mother showed weak correlations with several subscales of ERC, did not play a significant role to predict emotion regulation strategies in adolescents. Therefore, the healthy family function can play a crucial role in the formation of emotional stress during adolescence, and prevent many challenges during adolescence. Manuscript profile -

Electrophoresis of high molecular weight (HMW-GS) and low molecular weight (LMW-GS) glutenins was undertaken by SDS-PAGE with sequential extraction. For HMW-GS, three tetraploid accessions including TN-11372, TN-11734 and TN-11743 were identified which did not contain any alleles of Glu-D1 locus. In Glu-A1 locus, 83.33% of the landraces had null allele and 16.67% of them had subunit 2*. In Glu-B1 locus, subunits 7+8 had highest frequency (36.67%) and alleles 13+16 and 21 showed lowest frequency (3.33%). One exceptional subunit related to this locus was characterized in accession TN-11384 which named 6*. In Glu-D1 locus, subunits 2+12 were identified in 77.78% of accessions and subunits 3+12 were characterized in other accessions. In Glu-3 locus, 12 LMW subunits were observed with different mobilities and genetic diversity index (H) was 0.844. The high diversity characteristics of seed storage proteins may be useful in identification of varieties and ploidy levels and determining bread making quality in order to improving wheat quality characteristics.
