Considering the importance of the multi-core spatial structure pattern, especially for large cities with high populations and diverse and complex activities, the present study aims to evaluate the spatial structure of Tabriz city from the perspective of multi-core pattern development based on the spatial distribution of functions and population across the city. The present study employs a Quantitative Correlational Research method. The documentary method is used for data collection, and various techniques such as mean center, standard deviational ellipse, kernel density estimation, location quotient (L.Q.), nearest neighbor index, and geographically weighted regression are applied for data analysis. The study examines six functions: religious, educational, commercial, healthcare, industrial, and administrative. The findings suggest that the spatial distribution of functional cores, except for industrial and commercial functions, exhibits a single-core spatial structure in the city center. Also, the results indicate that the correlation between functional cores and the population of Tabriz city, based on the spatial regression test, is moderate. Accordingly, an imbalance in the distribution of functional cores in Tabriz City is evident. Therefore, Tabriz is located in a single-core state, and due to the increase in the distribution of administrative and medical functions in the eastern and industries in the western, it can become a multi-core model.

The main reason for this is that various optimization problems, such as the complementary linear programming problem, can be written in the form of a robust equation that is easier to solve. The main purpose of this paper is to present a duplicate method for solving the equations of magnitude. Actually, in this paper, by introducing a scalar matrix, an improved generalized Newton method is proposed to solve the Absolute value equation. This new method is based on the methods of Mangserin [1] and Li [2]. In fact, if in the matrix A + αI-D, the value of the identity matrix coefficient is equal to zero, the Mangserin method and if the coefficient of the same matrix to one, the Li method is obtained. when all the singular values of the system matrix exceed one.

This approximation is ‎based on the space-time radial basis functions (RBFs) and the Sinc quadrature rule. In this ‎method, we use Gaussian radial basis function and don't distinguish between time and place ‎variables and the collocation points have both the coordinates of time and space. We use the ‎Sinc quadrature rule with single exponential transformation to approximate the integral part of ‎fractional derivatives. The chosen fractional derivatives is Riemann – Liouville.‎This method is implemented on two examples with different values of the fractional ‎derivative order. Obtained results illustrate the effectiveness of our method and sh ow that ‎one can obtain accurate results with a small number of the collocation points for the radial ‎basis function. It should be noted that all calculations in this paper have been done using ‎Mathematica software.‎ Manuscript profile -

We have also investigated the transition of historical view point regarding the concept of national and international security through extensive accounts of the transitions of the security concept dated back to the cold war era. Besides, after careful consideration of security paradigm transition ( realism, liberalism, constructivism), we attempted to theorize security both subjectively and objectively in a way to present its conceptual transition in U.S. foreign policy. Underlining the extensive concept of security, the results indicated a need for an inter paradigm study in terms of ontology, epistemnlogy and discourse regarding any analysis and investigation in the area of security.

Bitcoin is one of those digital currencies that are considered to be trading more than other currencies. A review of Bitcoin prices is indicative of fluctuations in this market, which increases probability of existing bubble. In this regard, using the monthly data for the period from 08/2013 to 01/2018, the bubble of this market and the single or multiple type of bubbles were investigated. The method used in this study is A recursive unit root test, which was used in the form of SADF, RADF and GSADF tests. Based on the RADF test, there were four bubble periods (March 2015- April 2015, Decembar 2015- March 2016, July 2016- January 2017, September 2017- not disappeared) that had single structures. Based on the SADF test, there was a continuous long bubble period (August 2016- not disappeared), which has a single structure and has not yet exploded. Finally, based on the GSADF test, there were three bubble periods (March 2015- May 2015, Decembar 2015- March 2016, July 2016- not disappeared), that two first bubbles have same structure (March 2015- May 2015, Decembar 2015- March 2016) and the third one has multiple structure (July 2016- not disappeared).

The main goal of this paper was to study Foster non-linear model as a new approach in contrast to previous offered models. Design/Methodology/Approach: This Survey research was conducted by a questionnaire that developed by the researcher based on existing criteria at the Foster’s thesis (2003). Total of 110 questionnaires were distributed and 105 of them were returned. Findings: The results showed different levels of correspondence in interdisciplinary and single-disciplinary researcher’s information-seeking behavior with Foster’s non-linear model in general and also with the contexts and triple core processes, too. The hypothesis test showed a significant difference in the the level of information seeking behavior matching between the two groups of studied researchers with the model. Conclusion: There is an essential need to review this model, especially in determining the weight and importance of each core processes and contexts in modeling the information seeking process.

It is also attempted to compare the Muller’s and Karbassi’s methods for determining the pollution index and the natural and anthropogenic share of the mentioned elements in the study area. in of Geoaccumulation index (Igeo) and (Ipoll), heavy metals of natural and anthropotogenic fase contribution in the region. Method: To perform this study, 3 samples were systematically collected from soil at the depths of 5 - 25 cm and mixed together to make a compound sample which was transferred to the laboratory. The concentrations of manganese, nickel and lead were measured using a spectrophotometer. Then the Muller’s Geoaccumulation index (Igeo) and the Karbassi’s Pollution Index (Ipoll) were employed to determine the intensity of pollution in the study area. Findings: The results of bulk digestion showed that concentrations of Mn and Ni are lower and concentration of Pb is higher than the maximum average concentrations in the Earth’s crust and shale. Igeo was in the range of 0-1 and Ipoll was in the range of 1-2 for all metals, respectively showing that soil pollution is classified as unpolluted and slightly polluted. Discussion and Counclusion: Karbassi’s Ipoll was found to be more efficient than Muller’s Igeo in determining the amount of contamination in the region. The share of heavy metals in anthropogenic phase was determined as the following order: Pb (16%)> Ni (8%)> Mn (5%). Manuscript profile -

However, hospitals frequently overlook objective criteria when evaluating and selecting waste disposal firms, relying instead on subjective judgment and past experiences. This research proposes a decision-making framework that presents a hybrid model combining multi-criteria decision-making and linear programming. The primary objective of this study is to propose a safe and efficient method for outsourcing disposing of or recycling hospital waste. Material and Methodology: This study presents a framework for decision-making in hospital waste disposal, addressing both single and multiple outsourcing scenarios. Firstly, the literature is reviewed to identify the criteria for evaluating waste disposal firms. The DEMATEL method is employed to explore the cause-and-effect relationships among these criteria, selecting the most significant ones and visualizing their causal relationships in a network format. The analytic network process (ANP) method is then utilized to evaluate and choose the most suitable waste disposal firm in a single outsourcing scenario. Additionally, to mitigate the risks associated with single outsourcing, a linear programming model is introduced for multiple outsourcing. This mathematical model determines the optimal allocation of waste quantities to various waste disposal firms, aiming to maximize the overall amount of waste disposed of by these firms. Fidings: The framework introduced in this study was put into practice to assess and choose hospital waste disposal firms in Tehran. Through a comprehensive literature review, 10 evaluation criteria were identified. Among these, the six most influential criteria were selected using the DEMATEL method, and their causal relationships were depicted in a network. The ANP was employed to assign weights to the evaluation criteria and the candidate firms. The evaluation criteria, in descending order of importance, include qualified human resources, recycling and disposal capacity, experience, cost, collection and transportation infrastructure, and waste disposal and recycling technology. Furthermore, a linear programming model was solved using Lingo software to optimize the allocation of waste among the candidate firms. Discussion & Conclusion: The decision-making model presented in this article offers advantages to both hospital officials and urban pollution control officials in the context of outsourcing sanitary waste disposal. The outcomes obtained from implementing the proposed framework demonstrate that decision-making based on this model not only benefits hospitals in selecting a suitable firm but also helps to mitigate conflicts of interest and disagreements between hospitals, sanitary waste disposal firms, and urban pollution control officials.

The models used to judge stock selection skills are Jensen (Single Factor) and Carhart (4 Factor). Market timing ability is evaluated using the Augmented Treynor- Mauzey Model. To test the hypothesis of time series data regression is used. The results showed that among research topic funds, according to the single factor model (jensen’s measure), only in one fund it also at a confidence level of 90%, security selection to be seen as significant, and in confidence level of 95%, security selection not significant in any case. according to the 4-factor Carhart model, only in one fund it also at a confidence level of 93%, security selection to be seen as significant, and in confidence level of 95%, security selection not significant in any case. Market timing in 4 of 5 samples was found to significantly that unfortunately every 4 cases were negative. Manuscript profile -

Findings of descriptive-analytical study show that Holy Quran implies absolute desirability and redemption of marriage because of its vital role. The Qur'an's supportive pattern of divorced women also reflects the same emphasis on marriage (and not remaining single). Qur'an's tone on polygamy is not hortatory and encouraging, but merely an expression of its permissibility. The purpose of Quran in knowing polygamy and temporary marriages formal, is to provide a solution to some of the social needs. What is emphasized in Holy Qur'an on main criteria of marriage is the necessity of being in the same dignity (for couples). Holy Qur'an also determines specific criterion for marriage and the role of women in marriage highlighting Divine Book's attention to the legal and ethical rules and commands of marriage as well as its social functions including expanding social interactions, maintaining women's respect and character and children education.

The difference of opinion became what we know today as the generation gap. In the twentieth century, Michel Foucault presented a broad theory called "discourse analysis" in which he emphasized that words have different meanings in different situations. In this article, we try to examine the image of family relations in the contemporary Algerian family by examining the novel "AlsaghFawghAlsagh" by Amin Al-Zawi and examine the generation gap between family members. The research method in this article is based on a critical method and We intend to explore how and to what extent society changes affect family events and the prevailing discourse in the family within the contemporary novel. We derive in our study from the discourse analysis of Michel Foucault. Discourse for him is used to know the factors outside the text framework and their impact on the content. Perhaps one of the most important points that can be mentioned as a result of this article is the independence of family members and consequently the expression of personal positions and as a result creating differences between different generations and views, which can be said to be a constant conflict between tradition and Modernity also fuels these differences.

The genetic algorithm mimics the evolutionary concept of generational survival. If the population develops through generations of individuals, the overall competence of the group will increase. If certain individuals are not competitive enough to survive, they are doomed to die and their genetic traits removed from the population. So the genetic algorithm method is a nature-inspired method. Below we define the concepts used in this method and explain the method of finding optimal solutions using genetic algorithm. Manuscript profile -

The novelty of this research includes the use of the equivalent single machine (SIME) method to implement and improve the two important and main parts of the TSCOPF problem. Part 1: SIME is used to analyze the transient stability of the power system. Part 2: SIME equates a multi-machine system to a single machine connected to an infinite bus (OMIB). The instability angle obtained from the equivalent OMIB angular path is used to construct the transient stability constraint. In this method, the transient stability constraint is included by SIME in each iteration of the TSCOPF method to accurately determine the dynamic behavior of the power system. Differential equations representing the dynamic behavior of system machines are decomposed into algebraic equations according to the trapezoidal rule. The proposed load distribution model is tested and analyzed on the IEEE 9-bus system (WECC). Manuscript profile -

Despite the importance of burying solid waste as one of the most efficient ways in waste management cycle, its basic standards have been neglected in many parts of Iran. Recently, the Geographic Information System (GIS) has been recognized as a suitable tool in landfill site selection studies. In addition, Multi-Criteria Decision Making (MCDM) has been introduced as a well-known technique to investigate complex decision-making issues such as landfill selection, and the Analytical Hierarchy Process (AHP) is one of the well-known methods of MCDM. In general, landfill siting based on GIS has two main screening steps including first, removing unsuitable land areas and then ranking remaining areas. Additionally, waste landfill siting mainly depends on information availability related to population characteristics. In this way, it is needed to forecast population in the future. Qazvin as a province in the central part of Iran, is facing a population growth in the recent decade. Comparing the population in 2011 and 2016, it showed an increase of about 1.17 percent of average annual growth in Qazvin's population. Therefore, with regard to the increasing population in this newly established province, it is considered critical to conduct a landfill site selection procedure. To achieve the aim, the present research intended to establish a landfill site regarding environmental factors and using integrated GIS-AHP approach which incorporated into the population forecasting in Qazvin province.Materials and Methods The present study was conducted in three main steps include; initial waste Landfill siting using Multi-Criteria Evaluation (MCE), determination of the required landfill area based on population forecasting up to 2046 and final locating of waste landfills using Single Objective Land Allocation (SOLA) in TerrSet software. In the first step, the initial Landfill siting was conducted by the integrated GIS-AHP approach during the process of identifying and selecting the criteria, weighting the criteria, standardizing the criteria and finally integrating the criteria with the Weighted Linear Combination (WLC) method. In the second step, the area required for waste disposal sites was estimated based on population growth rate, per capita waste generation (kg per day) and average groundwater depth. In order to forecast the population growth up to 2046, reports of Iran's Plan and Budget Organization was used. In the third step, the final sitting of the municipal solid waste was determined with a SOLA in TerrSet software. The initial suitability map was entered into the model as the base input. Also, the estimated area from the second step. In this study, two scenarios were implemented. In the first scenario, in order to select the appropriate locations, the condition of having the highest value of the map was applied, and in the second scenario, in addition to the mentioned condition, the need to have a 10 km buffer for each of the selected options was considered.Results and Discussion According to the expert's opinions and environmental standards, seven ecological and socio-economic criteria were suggested that each criterion consists of several sub-criteria. Then by implementing the AHP method on the experts’ judgment, the final weight of each criterion and sub-criterion was obtained. After preparing the GIS layers, each of the invoice layers was standardized according to the functions in the fuzzy membership tool and was classified with a range of numbers from 0 to 255. The results showed that in the study area the combination of AHP and GIS for landfill siting is significantly compatible with field observations. GIS is a very powerful tool that could provide a quick assessment of the study area to determine the appropriate location for landfill. The selection of criteria was one of the most important steps in this research. The environmental factors should be considered along with economic factors in choosing a landfill site. Therefore, the eight main criteria of distance from the road, elevation, slope, distance from residential areas, distance from surface waters, distance from protected areas, geology, hydrology and land use were used in their research. The criteria were divided into three parts; morphological, environmental and socio-economic. In this research, in addition to the mentioned criteria, various natural and human parameters such as distance from energy transmission lines, distance from industrial towns and railways, etc. were also used to double the comprehensiveness of the present study. By integrating standardized GIS layers with WLC method, the initial map indicating the distribution of suitability of different sites to waste disposal location in Qazvin province was prepared. By implementing the AHP method into each criterion and combining in GIS, the waste disposal areas in the study area were classified into four classes. According to this classification, the initial map was divided into very good, appropriate, inappropriate and very poor areas. According to the initial suitability map, the cities of Takestan, Abik and Buin Zahra, with an area of 50.15, 14.55 and 54.48 km2, respectively, had a good condition for landfill location. The suitable places for landfill were the flat territories near the urban and had the advantage of the appropriate access path. Then, using land use allocation algorithm, the best landfill site was identified in two scenarios and three location options for each scenario. In the first scenario, the maximum map value was applied to select the location options. In the second scenario, in addition to the mentioned condition, a 10 km buffer was considered for each location option. Finally, site number one of the first and second scenarios and site number three of the second scenario were identified as priorities. Site number one was selected in the range of Buin Zahra city and near the village of Elahabad. While site number three was located 15 km away from the waste management department of Qazvin city and near the Zinabad village.Conclusion It should be noted that not only the final location of municipal solid waste landfills has not been determined in recent years, but also a comprehensive program in the field of reducing waste production and implementation of waste separation plans from the source in the studied cities has not been implemented.Formation of a future forecasting section on the organizational structure of landfill waste management systems can not only reduce environmental risks but also bring sustainability to economic and social resources.

37 - Creating a graphical user interface (GUI) to automatically calculate the land surface temperature and use the results in evaluating temperature changes in land uses in Ardabil city
Hossein Fekrat Sayyad Asghari Saraskanrood Seyed Kazem AlavipanahBackground and Objective Land surface temperature is a vital indicator for studying environmental changes, hydrological conditions and the energy balance of the earth, which can also be used to monitor the temperature changes of cities. The lack of meteorological statio MoreBackground and Objective Land surface temperature is a vital indicator for studying environmental changes, hydrological conditions and the energy balance of the earth, which can also be used to monitor the temperature changes of cities. The lack of meteorological stations in most parts of the country, including the study area, has created information limitations in the field of surface temperature data. There are also a large number of non-remote sensing users who need LST maps, and most of them are not familiar enough with LST computing software and inevitably have to spend a lot of time mapping to prepare their maps. This process can be time-consuming even for remote sensing professionals if the number of images is high. The use of valid data for validation that has the least time difference with the satellite passes time is very important in estimating the accuracy of the results. By reviewing internal research similar to the one under study, most internal studies used only meteorological station data to validate the results, the data recording time at these stations is different from the satellite passes time. In this study, due to the large area of the study area and the insufficient number of meteorological stations, in addition to the surface temperature data measured in synoptic stations, the land surface temperature in two ground stations was recorded simultaneously with the satellite. Creating a graphical user interface (GUI) to automatically calculate the surface temperature of Ardabil city with two single-channel and RTE algorithms and use the results to evaluate the temperature changes of land usesMaterials and Methods In this study, in order to automatically calculate the land surface temperature of Ardabil city from three types of data: Landsat 5 and 8 satellite images, land surface temperature data recorded at two meteorological stations in the study area and also due to an insufficient number of stations Meteorological data land surface temperature data measured with digital thermometers are also used as the satellite passes. After preparing thermal and multispectral images, first MODTRAN web computing software was used to model the atmospheric transferability and atmospheric coefficients were extracted. Then, to create graphical user interfaces and automatic calculation of LST, land surface temperature with two algorithms single-channel and RTE method with Landsat 5 and Landsat 8 satellite images for two dates: 31/07/2000 and 21/08/2019 in MATLAB software were coded and using these codes, graphical user interfaces were created for each algorithm and finally, an automatic land surface temperature calculator application was produced. Also, the land use map of Ardabil city for both mentioned dates was classified and extracted using a random forest algorithm in the Google Earth engine system environment with 7 classes. This algorithm has a much better performance compared to traditional methods such as maximum likelihood due to its hierarchical structure in selecting each pixel to the appropriate class. To validate surface temperature maps from two types of surface temperature data recorded in two meteorological stations and surface temperature recorded by a digital thermometer that simultaneously passes the satellite in two points of the homogeneous non-urban environment with agricultural use (alfalfa) and Bayer that product It was harvested, used. To evaluate the accuracy of land use maps, using Google Earth, which has a better spatial resolution than the image used, 248 ground control points were obtained from pure pixels of different land uses and used in the validation process. Also, statistical parameters such as error matrix, overall accuracy and kappa coefficient were applied to the output of both land use maps.Results and Discussion Using the codes written in MATLAB software, graphical user interfaces (GUI) were created and then the automatic LST calculator application was produced. The output of the application was surface temperature maps with single channel algorithms and radiation transfer equation (RTE) for 31/07/2000 using thermal image (band 6) of Landsat 5 satellite TM and 21/08 / 2019 was created by the 10 TIRS sensor band of Landsat 8 satellite. After comparing the output maps with the meteorological station and ground station data, the results showed that the single-channel method had the lowest temperature deviations compared to the stations in both years. After preparing LST maps and selecting the optimal algorithm (single channel), land use maps of Ardabil city were prepared using a random forest algorithm in the GEE platform. Statistical evaluations of the classification results showed that for 2000, the highest pixel interference was related to the middle and poor rangeland class, which has a 16-pixel displacement with residential and rainfed agricultural classes. Due to the improved spatial resolution of the Landsat 8 satellite compared to the Landsat 5, followed by better class separation, this pixel displacement in the 2019 user map shows a smaller value. The most common error was related to the aquaculture class, which had a displacement of 10 pixels with rich rangeland and rainfed agriculture classes. Finally, using the LST map and land use map, the temperature changes of the land uses over a period of 19 years were evaluated. By entering the input images and atmospheric parameters in the application, the land surface temperature was calculated with two one-channel algorithms and the RTE method. Evaluation of output maps with meteorological and terrestrial data showed that the single-channel algorithm with a difference of +2.5 and -2 with stations 1 and 2 for the year 2000 and with a temperature difference of +1.3, +0.9, -1 and -0.9 with stations 1, 2, 3 and 4 in 2019, respectively, had higher accuracy than the RTE method. Also, the results of validation of land use maps showed an overall accuracy of 0.95 and a kappa coefficient of 0.94 for 2000 and overall accuracy of 0.96 and a kappa coefficient of 0.95 for 2019.Conclusion Assessing the relationship between land surface temperature and land use maps showed that despite the significant physical growth of the urban sector over a period of 19 years, except for residential areas, all land uses in 2019 compared to 2000 with an increase in average surface temperature. It seems that factors such as the expansion of agricultural lands with irrigated cultivation around the urban area up to a radius of 10 km and the entanglement of these farms with the urban sector have a great impact on the temperature adjustment of the urban sector. In 2000, these lands were mainly under cultivation of rain-fed crops, and by solving the water problem (digging deep wells and water transfer projects), they became orchards and irrigated farms such as potatoes. Due to the high water requirement, these products also have high greenery, and this factor has increased the rate of evapotranspiration, followed by cooling of the cultivation area and the urban sector. Among other classes, in both years of water use, the lowest and the use of barren lands had the highest average surface temperature. The generated application can be run on any operating system that supports the exe format, and the user by specifying atmospheric parameters can automatically estimate the LST. This application can also be used in various sectors such as agricultural systems, and climate and water resources management. 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 -

The results show that methane adsorption on the nanotube is an exothermic and physical process accompanied with the adsorption energy of -340 meV. The amount of adsorption energy indicates a significant increase in the adsorption energy of methane molecule on the decorated nanotube compared to pure one (-80 meV). The proposed structure before methane adsorption is a bipolar magnetic semiconductor with a small gap (-150 meV). On the other hand, methane adsorption energy is about twice the energy gap. This allows the carrier to be injected into the nanotube due to the heat of the reaction, followed by a change in conductivity. Therefore, the proposed structure has the potential to be used as a sensor based on reaction temperature and conductivity change. Manuscript profile -

Due to the ability to use the waste steam in oil, gas and petrochemical industries for air conditioning and process cooling purposes, the steam type chiller is more widely used. In this study, the artificial neural network is exploited in the prediction of the steam single-effect absorption chiller performance since it is faster and has lower computational cost compared to thermodynamic modeling methods. The perceptron multilayer neural network with the error backpropagation algorithm, the hyperbolic tangent excitation function and the Levenberg-Marquardt learning method with 15285 data points and also the mean squared error estimation index are used. Inputs of the artificial neural network are the inlet cooling tower water temperature, inlet chilled water temperature, inlet steam temperature, outlet chilled water temperature and the solution heat exchanger efficiency respectively. Also, outputs of the neural network are the coefficient of performance and thermal energy consumption of the chiller. Results of this study show that the artificial neural network is capable to predict the coefficient of performance and the thermal energy consumed by the single-effect absorption chiller while the values of mean squared error are 3.183×10^(-7) and 7.466×10^(-8) respectively which verify the accuracy of the method proposed here in absorption chiller performance prediction.

In this type of camera, all pixels are used to create the image. For CCD-based cameras at other wavelengths, including infrared and terahertz, having all the pixels increases the cost of the camera. The aim of this study is to design and build an imaging setup using a single pixel method to reduce the cost of the camera and to reconstruct the target image using less data. We verify this method for visible band due to availability of visible light equipment that can be generalized this method to other wavelengths. We use a spatial light modulator (SLM) produces two-level optical masks with random distribution with 20 x 20 pixels and a size of 10 x 10 cm and illuminates the target at a repetition rate of 1 Hz. The reflection of each mask from the target captured by a CCD camera and then we average of all pixels of the CCD to equate it with a single-pixel detector. The target image is reconstructed using a compressive sensing algorithm. The process of reconstructing the target image is performed using a minimum number of masks. We use the two norms L1 and TV to retrieve the target image. The simulation results show norm TV is more successful in target image retrieval. Also, with increasing the number of masks, the success rate in retrieving the target image increases. Manuscript profile -

However, the usability of SCO is limited due to the high price of the raw materials used in it. The fermentation process using inexpensive agricultural and industrial wastes can solve this problem, which are applicable for the production of SCO. The use of these by-products as the main source of carbon in fermentation not only significantly reduces the overall costs of SCO production, but also causes the treatment of produced waste streams, thus reducing the negative effects on the environment. . Because various agricultural and industrial biodegradable by-products can be used in microbial fermentations. The purpose of this review is to classify and compare usable agricultural residues based on their availability. Single-cell oils are lipids from bacteria, fungi, yeasts, microscopic cruciferous algae, and protists. These lipids have different uses depending on their fatty acid composition. SCOs with high saturated fatty acid content are suitable for biodiesel production, while SCOs rich in unsaturated fatty acids are suitable for human and animal nutrition. Manuscript profile -

Accordingly, two single slope solar stills with same sizes containing conventional and modified by using porous layer are fabricated and tested, simultaneously. Black sponge rubber with low heat capacity and wick characteristic is selected as porous material. All experiments were performed in Semnan with geographical coordinates of 35° 33' N, 53° 23' E, Iran. Results showed that daily total water productions enhance by using sponge in solar still. Daily total water productions are 3263 and 3829 cc/m2 for conventional and modified stills, respectively. Accordingly, modified still produces 17.35% more distilled water in comparison with conventional one during one day. There is a direct relationship between trends of daily efficiencies of stills and trends of surrounding temperature or solar radiation intensity. Manuscript profile -

There is a catacomb in engraved rocks which was misinterpreted as storage for rainfall. Some scholars, local people, and internet materials have wrongly identified it as a storage place for water. The authors attempt to reject such claim and identify the chronology and functions of the site by surveying the site and drawing its plan and comparing it with foreign and Iranian similar sites. The tomb consists of a main chamber with attached spaces and a symbolic square yard that is integrated with stony staircases that reach to them and can be presented as rocky Urartu tombs known as “integrated single unit”. Apparently, in Urartu, tomb types indicated the buried people’s status and since catacombs usually were for royal family and local governor, understanding and presenting can be profitable for a better realization of the region in Urartu period.

The research methodology was applied in terms of purpose and quasi-experimental in terms of data collection, employing pretest-posttest design with control and experimental groups. The statistical population of the study consisted of all female heads of household (a single mother who is in charge of the family following a divorce) in district 5 of the city of Tehran in the year 2020-2021. The sample consisted of 36 single mothers who were selected through convenience sampling and were randomly assigned into two groups of experimental (n=18) and control (n=18). The research instruments included the Subjective Wellbeing Scale (Kiz & Magiarmo, 2003), World Health Organization Quality of Life- BREF Questionnaire (1994), and Life Orientation Test-Revised (Shearer and Carver, 1994). The subjects in the experimental group underwent the PERMA Model training program for 10 sessions of 90 minutes while the control group did not receive any training. Data analysis was performed using covariance test and SPSS software. The results of the study showed that PERMA Model training is effective on subjective well-being, quality of life and orientation of life in single mothers (P<0/01). Therefore, it can be inferred that the PERMA Model training enhances single mother’s subjective well-being (F=4,89, P<0/01), improves their quality of life (F=4,56, P<0/01) and life orientation (F=6,36, P<0/01). Therefore, according to the Above mentioned results results, it can be concluded that Perma exercises have been effective on these components by emphasizing and focusing on the five components of positive emotions, engagement, meaning, positive relationships and accomplishment.

For this purpose 45 subjects were selected by purposeful sampling from among foster care/irresponsible parenting adolescent girls’ care centers and were divided into three groups (individual , 15), (group, 15), (control, 15). The experimental groups received six ninety-minute sessions of positive-based psychotherapy sessions from Positive Psychological Intervention (PPI) of Seligman & Csikszentmihalyi (47), but the control group did not receive any intervention. The subjects completed the Beck Depression Inventory before and after the intervention and one month later at follow-up phase. The gathered data were analyzed using the ANCOVA statistical method. The results of the analysis indicated that the positive training on the individual group reduced the emotional symptoms of the subjects compared to the other two groups (P<0/01). However, in the follow-up phase this effect was sustained. Therefore, the results of this study suggest that positive interventions can be used to improve symptoms of persistent depressive.

The optimal management of its organizational dynamicity can profoundly impact productivity. Yet, close inspection of the existing literature indicates lack of a framework for managing organizational changes in CHQs. Hence, the purpose of this qualitative single case study is to bridge the gap and introduce a framework for managing the adaptation process in the CHQs. Initially, a specific and applied definition was offered for CHQ based on meticulous review of the related literature. Further, the construct was operationalized in the form of a questionnaire which was administered in one of petrochemical multi-business companies to serve the purpose of the study. The research data gleaned through open interview and studying related documents were submitted to thematic analysis. The findings underscored the CHQ’s environmental requirements, fundamental changes, orienting elements, parenting and managerial style and the maturity curve as the most significant factors influencing the policymaking of the adaptation process. Challenges related to each of the factors and the ways of handling them are discussed and a framework is offered for managing the adaptation process in CHQs. Manuscript profile -

That era’s political, social, cultural, and even religious structures, broadened the poets’ horizons and led the personal feelings, and inner emotions of poets with heartwarming thoughts to be reflected in different subjects in poems of this era and a collection of different lyrical literature emerged in their works. On the other hand, single-couplet is a form of stating these subjects. The poets’ books during this era are the most extensive collections in which ethical, spiritual, love-making, religious, teaching, and social issues with novel and new content show off in a short form of single-couplets and generally, the frequency of lyrical literature is more significant in this form compared to different literary forms. This article has addressed the lyrical aspect of Indian-style’s single-couplets and the variety of lyrical contents and has studied variables such as love, mysticism, pomposity, grievance, threnody, humor, patriotism, mystery, etc. in the poems of this era. The present research results show that virtual love, mysticism terminology, pomposity, and patriotism have the most frequency. The present research method is based on description and analysis.

This article attempts mainly to investigate the reasons for this lack of variable – speed drives. This paper deals with literature survey of various existing converter topologies, which have been proposed for adjustable speed single phase induction motor drives. Various converter topologies have been compared in this paper. Among these converter topologies, the adjustable frequency PWM inverter is the best choice for single-phase induction motor drives. However, adjustable-frequency drives have not been widely used with single-phase Induction motors. The open-loop constant V/F control law cannot be used with the single-phase induction motor drives as it is used with three phase motors. The variation of the operating frequency at lower speed range with constant load torque causes variation in motor's slip. A constant V/F control is suitable only over the upper speed range.

Firstly, they have high starting current which causes significant voltage drop, and secondly, they operate in a single speed mode and not in variable speed. In many home appliances, traditionally a discrete speed control method is used by changing the number of the poles. A proper solution for these problems can be achieved by using control drive systems. In this paper, a simple scalar control method is applied to control the speed of a permanent capacitor single phase induction motor (PCSPIM). The philosophy of this method is on the basis of simultaneous system’s frequency and voltage control on the machines terminals subject to V/f=cte. Simulation and practical implementation results clearly show the effectiveness of the simple V/f =cte speed control method for home appliances. Manuscript profile -

The buckling restrained braces were made in one and three steel core with the same tensile and compressive capacity. These braces were subjected to cyclic tensile and compressive loads in the laboratory under the ATC-24 loading protocol. Hysteresis cyclic performances of each brace were obtained and examined. Then, the one and three core buckling braces were placed diagonally in a steel moment frame and their seismic performance and response modification factors were obtained using adaptive pushover analysis. The results indicated that the three core brace has 16.3% and 8.8% higher energy absorption and damping capacity. In addition, the damping in the three-core brace in drift 2.5% is 8.8% higher than the one core brace. Mean value of response modification factors for steel moment frame with one-core brace is 8.11 and steel moment frame with three-core brace is 9.14. In conclusion, the three-core brace has higher energy absorption and damping capacity and the ductility of the steel moment frame with the three core brace is higher than that of the frame with the one core brace, which presented the three-core brace has more acceptable seismic performance and is highly recommended for rehabilitation Manuscript profile -

This kind has more effective length than usual sharp tip weirs. In this regard, they can pass more flow than usual weirs for channel with similar width and height. In this study, effective geometrical parameters on single cycle labyrinth weir flow coefficient are measured by means of FLUENT software in three-dimensional way. To model turmoil, k-Ɛ model RNG method and to position free surface profile, VOF method are used. The results of numerical models are compared with those of rectangular weirs with same width. The results for specific H/P show that vertex angle increases with flow coefficient increase and rectangular weir performance of same width is less than single cycle labyrinth weirs, since in same width channel the interference of abscission blades is more severe than single cycle labyrinth weir and such an interference in vertex causes the flow coefficient decrease comparing with single cycle labyrinth weir. Moreover, single cycle labyrinth weir in less hydraulic loads has appropriate performance and ascending trend of flow coefficient. Manuscript profile -

In the meantime, the spatial structure and multi-core urban development due to the number of centers can form relatively uniform, balanced and homogeneous structures on the city level and distribute activities and population in a suitable way. GoalConsidering the importance of the multi-core spatial structure model, especially for large cities with high population and diverse and complex activities, the aim of the present research is to evaluate the spatial structure of Tabriz metropolis from the perspective of the development of the multi-core model.Methodology The research method in the current research is quantitative with an analytical-exploratory nature, in order to analyze information was used in the function distribution section, the spatial coefficient (LQ) model method and weighted geographic regression, and in the population growth section, the growth rate method. Geographical area of research The geographical scope of the research includes Tabriz metropolis. Results and discussion The findings of the research show that the spatial structure of Tabriz metropolis can be seen in a bipolar way and the central area (area 8) and the east of the city (area 2 and a part of area 1) have occupied most of the functions. However, due to the expansion of functions in the north of the city and with proper planning and proportional distribution of functions in other areas (south and west), it is possible to provide the preparations for the spatial structure and multi-core urban development in Tabriz metropolis. Conclusion The results indicate that centrifugation is quite evident in Tabriz metropolis and new population nuclei are increasing in the eastern, northern and western parts. Manuscript profile -

The business environment needs special attention and support and planning. The experience of developed countries shows that without paying attention to the business environment and supporting it, one cannot expect economic improvement and business prosperity and ultimately sustainable development, the business environment in our country is no exception to this rule. And it is necessary to pay serious attention to it and try to improve the business environment. One of the effective ways to improve the mentioned space and perhaps the most important way is to create and run a single window for starting a business, which has been experienced in other countries. In Iran, the establishment of a business start-up window was put on the agenda as a solution to improve this space, and it was implemented in 2018. The following article tries to provide solutions to improve it as much as possible by examining the reasons and necessities of creating such an environment while analyzing the related documents and how to start it.

Unfortunately, researchers have focused mainly on reading interventions and equal emphasis on timely interventions on spelling has been neglected. The purpose of this study was to investigate the efficacy of a multi-component spelling instruction in 4 students with specific learning disorder in spelling in an ABA design. Intervention was presented in 12 sessions and data were analyzed using visual analysis and quantitative methods by R software. Non-overlap of all pair's analysis (NAP) confirmed a significant increase in the spelling performance of 4 participants compared to baseline. In addition, findings did not show a significant reduction in participants' performance between the intervention phase and the maintenance phase (A2). Findings of this study seem promising to provide a multicomponent approach to treatment of multi-component deficits in specific learning disorders. Manuscript profile -

This study was aimed to evaluate the production of Aspergillus niger single cell protein and simulation of cell biomass production based on several un-structured models. Materials & Methods: In this experimental study, the fermentative process of single cell protein production was conducted in batch submerged culture with optimum culture medium formulation at 250C, pH 6 and 300 rpm for 200 h in an incubator shaker. At the end of process, the content of shaker flasks was used to analysis glucose concentration, cell dry weight and protein content in cell biomass. Results: The result simulation by Monod, Moser and Logistic models showed 92% 63% and 83% similarity, respectively. Increase in the pH from 3.5 to 6 caused 71% enhancement in protein content in cell biomass. However, pH more than 6 led to decrease in the cell biomass protein content and this values reached to 29% a pH 7. Increases in the initial glucose concentration from 10 to 50 g. L-1 did not show considerable effects on the cell biomass protein content. Cell biomass protein content of the media containing 50 g. L-1 initial glucose was only 5.67% more than the medium contained of 10 g. L-1 initial glucose. Conclusion: The Monod kinetic model was proposed as a suitable model to simulate A. niger behaviour. Furthermore, pH of the media affects cell biomass protein content. However, initial glucose concentration in the media did not show significant effects on the cell biomass protein content.

According to his theory of grace, which believes in the arc of descent and ascent, he believes in the obligatory grace of all beings, both material and abstract. His thought on the type of material and immaterial relationship and the way these two concepts influence each other is such that he has reached the inability to prove the physical resurrection and has left it to the Shari'ah. Based on his talking about cosmology, which divides beings into single and material ones, he comes to the conclusion that physical resurrection is not provable and the words of the Prophet must be trusted. The main question is: what are the consequences of the material and abstract concept in Ibn Sina's philosophy upon his psychology and eschatology. The current study aims to clarify the consequences of these two concepts in Ibn Sina's philosophy by examining the definition, and then he considers physical resurrection as an unprovable proof with these two concepts.

By acknowledging the international relations after the collapse of the Soviet Union, the world is practically ruled by a single-polar and despite the presence of China, Russia and the European Union in some global competition, still the hegemony of Washington almost exist. This article in response to the question of "The future of international order in the horizon of 2030?" has attempted to advance the global order based on the Games theory. Authors by using the " Scenario " method, argued that due to the constant effort of the States and a new actors such as India and Brazil to gain power in political, economic, cultural and military, global order will be changed. On the other hand, the USA's efforts to safeguard its hgemoni will cause the actor to maintain its focal focus, as a result of the current single-polar system to a single-multi-polarization system with the aforementioned focal classification and multi-focus (China, Russia, European Union, India and Brazil) will be changed.

In this paper, in addition to Singular Spectrum Analysis (SSA), a Genetic Algorithm (GA) is used to find the optimal window length and cut-off point, the objective of which is to find the minimum value for the correlation function between signal and noise components. Therefore, first, ten-year data of the overall index of Tehran Stock Exchange during 2009 to 2018 were implemented in three using the SSA method. Then it was solved in the form of an optimization problem by a genetic algorithm. The results of the first hypothesis showed that signal and noise resolution is possible in the SSA method. Also, according to the results of the research, Singular spectrum analysis based on genetic algorithm with an absolute value of less than the average value showed an improvement in prediction accuracy. Finally, considering the lowest weight correlation between time series components for signal and noise separation (finding the cut-off point) and then obtaining the optimal window length in the SSA based on GA, indicates the fact that the amount of parameters can be changed. Improve the performance of the SSA method to be useful. Manuscript profile -

Determining the proper pattern for forecasting volatility can play a significant role in decision making. In the old econometric models it is assumed that the component of error constant during the sample period. But in many financial time series it is observed that during periods of volatility is very sever. Under these conditions, the assumption of the exictence of the equivalence of variance is no longer reasonable. In the present paper, the GARCH, IGARCH, EGARCH, GJR-GARCH, FIEGARCH, HYGARCH, and MRS-GARCH two-regime models were evaluated in prediction of OPEC crude oil price volatility during 2010-2016 based on their RMSE error criterion. The results of this evaluation show the superiority of the Markov Switching GARCH Model on the 5 and 22-day horizons. Also, the long-term FIEGARCH memory model in predicting horizons of 1 and 10 days has better performance in predicting oil price volatilities than other competing models. Manuscript profile -

Using purposive sampling method, this cross-sectional study was carried out on 50 children of single-parent families and 50 children of nuclear families who were homogeneous in terms of their age. The study made use of the inventory of school motivation (ISM) (McInerney & Sinclair, 1992), adolescent multidimensional social competence questionnaire (AMSC-Q) (Gómez-Ortiz & et al., 2017) and academic identity status questionnaire (AISQ) (Wass & Isaacson, 2008). In this study, Multivariate analysis of variance (MANOVA) was used for data analysis. The results of multivariate analysis of variance showed that there is a difference between academic motivation, social competence and academic identity among children of single-parent families and nuclear families. In this way, the children of single-parent families have lower scores in academic motivation, social competence and academic identity (achievement) than the children of nuclear families. The results also show that children of single-parent families have higher scores in academic identity (moratorium, diffusion and foreclose) than children of nuclear families. These results have important implications for family structure for their children's academic functions. Accordingly, educational psychologists and educational counselors can benefit from the results of the present study to improve the educational problems of single-parent children. 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 Microstructural characterization of the coatings was performed by optical microscope and scanning electron microscope equipped with energy dispersive spectroscope. Hardness of coatings is also measured by Vickers method under the applied load of 30 gram-force. Isothermal oxidation and thermal shock tests are done at 1000 and 950ºC respectively. Post-spray results show that the use of nitrogen gas shroud is useful and coating achieved by nitrogen shroud has less oxide and porosity and has more homogeneous structure. Results from isothermal oxidation show that TGO layer growth rate in the specimen sprayed by nitrogen shroud is less. Thermal shock test shows that the specimen sprayed by nitrogen shroud has more resistance against thermal shock due to layer by layer and regular growth of TGO and having less oxide and porosity in comparison with the same specimen sprayed without nitrogen shroud. Also, the microhardness of sprayed coating without nitrogen shroud was 35 Vikers more than the applied coating with nitrogen shroud. 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 -

Russia's relations with Ukraine as a neighbor country in the region have embraced a painful separation and reflects the complex process of mutual identification in both countries. Hence, the Ukrainian crisis has always been responded to by Russian hardware power, the latest of which was the crisis in the Kerch Strait and the Sea of Azov, which has faced Russia's strict response to the Poroshenko’s sabotages. The present article seeks to answer the question of how Russia has managed the Ukrainian crisis and what techniques and tools have been used? The answer to this question is that the logic of the Russian approach to managing international crises suggests that, because of the importance of Ukraine for this country, Russia has managed the crisis in Ukraine in the form of crisis management models based on asymmetric, single line and single-multi-polar balance of powers, using hardware and software levers. The research methodology is based on a descriptive-analytical strategy. Manuscript profile -

Authors usually suppose that weights are given in advance, and focus on the solution methods for the specific problem at hand. However, weights directly settle the class of optimal solutions, and are of utmost importance in any practical scheduling problem. In this study, we propose a new weighting approach for single machine scheduling problems. First, factor weights to be used in customer evaluation are found by solving a nonlinear optimization problem using the covariance matrix adaptation evolutionary strategy (CMAES) under fuzzy environment that takes a pairwise comparison matrix as input. Next, customers are sorted using the technique for order of preference by similarity to ideal solution (TOPSIS) by means of which job weights are obtained. Finally, taking these weights as an input, a total weighted tardiness minimization problem is solved by using mixed-integer linear programming to find the best job sequence. This combined methodology may help companies make robust schedules not based purely on subjective judgment, find the best compromise between customer satisfaction and business needs, and thereby ensure profitability in the long run.

This study focuses on two types of nanocarriers: single-walled carbon nanotubes and boron nitride nanotubes, each of which carries a drug with an alkylating agent: chlorambucil. This research investigates the stability of these carriers at different temperatures and solvent conditions. Using quantum mechanical calculation methods, the interaction between the anticancer medicinal compounds chlorambucil with two nanocarriers (carbon nanotubes and boron nitride nanotubes) was investigated in a range of temperatures and different solvent environments. Checking the thermodynamic parameters through molecular mechanics calculations, the hardness, polarity, Gibbs free energy parameters, as well as the HOMO and LUMO gap of the compounds were calculated. Also, using molecular mechanics calculations, optimal force fields and lowest energy states were determined in each solvent. The findings of this research are promising for the development of targeted drug delivery systems and the preservation of these vital medicinal compounds. Manuscript profile -

The main factor included drought stress based on evaporation from class A pan at two levels of 70 millimeters as control and 140 millimeters as drought stress. The sub factor was 14 factorial combinations of mycorrhiza fungi application and non-application with seven corn hybrid including SC260, SC301, SC400, SC4015, SC703, SC704, and SC705. To evaluate tolerance and sensitivity of corn hybrids to drought stress, the stress tolerance index, stress sensitivity index, tolerance index, mean productivity and the geometric mean of the product were used. Two-year complex analysis showed that in most of the studied traits, the interaction of year and stress was significant in corn hybrids. Seed yield in two years was increased more with mycorrhiza application in hybrid SC301 than other hybrids considered as the most tolerant corn hybrid to drought stress. Indices of stress tolerance index and geometric mean productivity had positive and significant correlation with grain yield in both years. Also, mycorrhiza application had a different effect on mitigating of drought stress effects, but in general it increased maize yield under drought stress conditions. Manuscript profile -

In this study, two levels of N-Fertilizer including Amonium Nitrate and Urea with amounts including 100, 160 and 220 Kg of pure Nitrogen per hactar as a factorial design in compeletly randomized blockes with four replications was run. One of plots in each treatment was considered as control without N-Fertilizer receiving. Plants was planted as farrow system on the rows with 75 cm intervals and 67.000 plants/ha density in 23th of Ordibehesht. N-Fertilizers were applied in three times including simultaneously with planting, four and eight leave stages as top dressing. The plants were selected from 5 m2 of three middle rows for determining of seed yield and biological yield in physiological ripping stage and 15 plants randomizly were selected from each plots for yield component and head numbers in a plant in row and seed number in row were counted and 1000 seeds weight was evaluated. It is revealed that Amonium Nitrate application has higher yield than Urea application and 160 and 220 Kg/ha of pure Nitrogen has the same or more then yield of control and 100 Kg/ha treatment. The reason of high yield in Amonium Nitrate treatment has contributed with corn efficiency in Nitrogen Uptake. Low yield in Urea treatment is related to Nitrogen wasting by sublimitation and washing.
