The proposed approach is presented using smart mobile phones for online digital imaging for customers. In this work, a fuzzy clustering has been used to categorize the characteristics of the images of different people and by applying them to different machine learning methods, a combined technique of machine learning classification methods has been presented to improve performance and increases strength against various attacks. Also to reduce the complexity of machine design for operational tasks, the technique of reducing features extracted from face images with the help of genetic algorithm has been used. In the last part, in order to make a decision for authentication selected by machine learning systems, a fuzzy logic system is presented based on the highest accuracy of identifying the desired person. Using a public dataset, the experimental results showed that the genetic algorithm-based technique is the best feature selection to create an implicit authentication method for the smartphone environment. The results showed an accuracy of about 99.80% using only 30 features out of 77 to authenticate users. At the same time, the results showed that the proposed method has a lower error rate compared to the related work. Manuscript profile -

It overcomes the physical distances by various modes of transportation, and is able to distribute data and information through telecommunication tools. Generally, the challenge created by speed is its sudden and hasty effect in a physical or even virtual environment which can lead to non conformities and a kind of disruption in present function of the system and would be harmful to the new agent, the environment itself or other users of it. So the pervasive impact of speed in changing communities and the human settlements is revealed. In detailed point of view, the study of variety of technological tools and the plurality of physical infrastructures in Shiraz urban structure shows the emergence of multiple speeds that led to the complexity, extension and dispersion of the city. Therefore, this amount of change in a short period of time caused a serious problem especially in measurement and evaluation of the city's structure. On this basis, the goal of this article is to gain a comprehensive view of speed, furthermore achieving an interrelationship between speed and urban structure is considered. This is investigated and analyzed through four speed ages extracted in both global and national scale. The objectives would be obtaining the urban corridors in the structure of Shiraz city in four speed ages which has the highest potential of mobility and this is coinciding with the definition of speed extracted in the epochs mentioned before. The proof of this claim is performed through space syntax analysis and its most practical criterion which is called the integration value. Moreover, in order to carry out a comprehensive and detailed investigation of speed in the present age, the study of different modes of transportation comprised of bus corridors, special taxi corridors and metro stations is done. Also the network analysis in physical context which has been done through space syntax, is applied. Besides, the virtual infrastructure of two main telephone portables in Iranian networks including Irancell and MCI coverage is studied. The overlapping of the above maps results the multi mobility-multi speed corridors in the structure of Shiraz which is comprised of a wide range of speed between minimum and maximum rate in the categories of natural speed, mechanical speed and virtual speed. These corridors achieve their multi functional characteristics through a historical and evolutionary process. The aforementioned corridors are the main streets ending to the five entrances of Shiraz city, number of corridors agglomerated in central part of city, and many east-west corridors versus few north-south corridors scattered in different city directions. As a result, in order to make a coherent and integrated structure, it is important to consider proper distribution of corridors in the north-south direction along with east-west direction also making an appropriate connection between these directions is suggested. The augmentation and reinforcement of south and east corridors together with north and west, also strengthening and emphasizing on the corridors connected to the peripheral settlements is recommended.

The author argues that the viciouscycle of power, that is the domination of political power overeconomic power, is one of the main reasons for the perpetuationof such a situation. In this regard, excessive class mobility is animportant obstacle to the emergence of autonomous classes inIran. It is expected that new class mobility (negative or positive)would be witnessed when there is a change in political system.Furthermore, there are other factors which affect the positionof classes in Iran. International system, religion and specificstructure of Iranian society are among these factors. Accordingto the author, understanding the question of classes depends onstudying the way in which power is executed in the society. Classis closely related to national identity, social cohesion and socialorder. Therefore, he concludes that the higher class mobility in asociety, the lower will become social cohesion.

In addition the moderating effect of customers’ experience with internet banking and mobile applications was conducted. Methodology: The present study is applied in terms of purpose and descriptive survey in terms of data collection. Using a questioner, the sample was selected using convenience sampling, which includes 450 bank customers who don’t use mobile banking. Out of 450 questionnaires, 400 were usable that analyzed with SPSS and Smart PLS 3. Findings and Conclusion: The findings reveal that intention of adopting mobile banking is determined by attitude toward mobile banking, which in turn is determined by attitude toward learning to use mobile banking. In addition, respondents’ past experience with internet banking and mobile applications did not have moderating effect on the relationship of attitudes and adoption intention. The result also showed that customers are interested in learning how to use mobile banking, also they have a lot of experience in using Internet and mobile applications. Therefore, the reason for customers' weakness of attitude depends not on the individuals and customers but on the performance of the bank and its infrastructure. Manuscript profile -

With mobile banking, customers are able to conduct banking services at anyplace and anytime and to connect banking service easily and quickly with mobile devices. Since the penetration rate of mobile devices is more than other technologies, if mobile banking accepted by the customers can decreases costs of banks and customers effectively. Worldwide researches has shown that despite there are numerous benefits that mobile banking provides for customers and banks, it is not accepted by the customers. Research on factors affecting the adoption of mobile banking by customers can be helpful in resolving this issue. Therefore, in this study a new model for the adoption of mobile banking taking into account the role of advertisement is presented. The proposed model combines the Unified Theory of Acceptance and Usage of Technology (UTAUT) with Task Technology Fit (TTF), and adds other influencing factors. Also, the proposed model is compared with the world known models in this research. Manuscript profile -

Higher education puts forward new demands and concerns and heightens the expectations of the educated people. Besides, the advancement of modern communication and information technologies accelerates this process. This process could result in a high potential for development; however, the strategy of states in the form of a step-by-step development in various fields has produced the adverse outcome for these countries. What would be the challenges before Developmental States in following a step-by-step development process concurrent with the promotion of education in the society? And how would the rise of new demands along with the objection of modern educated forces, who are focused on economic development, be understandable? Before answering this question, it must be clarified that the modern social forces, having different concerns from those of the planned steps of development, are recognized as the anti-development forces. The requirements of these growing classes of the society are not prioritized within the Development Plans of developing countries. Due to the lack of structural integration, these countries are deprived from utilizing the talents of these educated forces as the main source of development. Based on the necessity of solidarity and mobilization of social forces for development specifically the educated people, in this study we will analyze the Development Plans and by redefining development, we will try to identify the solidarity and balance required by the society for the realization of development as a strategy for fulfillment of development plans.

Moreover, the biological effects of amending these soil modifiers were evaluated throughmeasuring soil dehydrogenase and phosphatase activity. The experiment carried out in a completelyrandomized design with Factorial arrangement including 5 types of zeolite (modified with iron,manganese, aluminum, iron+ manganese and iron+ aluminum) and two levels (2% and 5%) of eachamendment.Results and discussion:The results of this study revealed that the applied amendments could increase the produced biomassand decrease both arsenic concentration in barely and arsenic extracted by DTPA. Also, furtherincorporation of amendments increased the activity of dehydrogenase, as a soil health index.However, the iron- and aluminum-modified zeolite was the only amendment which meaningfullyincreased the phosphatase activity. The reslts indicated that the iron-, manganese- and aluminummodifiedzeolite can be considered as a good alternative, low cost and environmental friendlyamendment for immobilization of arsenic in contaminated soils, and can mitigate the risk associatedwith arsenic entrance into the food chain.

Imperfect combustion of fuel leads to an increase in the amount of emitted gases (CO, NOX and HC). To prevent precipitation and reduce the pollution of such engines, choline stearate soap which is synthesized as nano structure, has been studied as a new additive cleaning agent. In this study, the researchers chose a suitable surface activator and by using it, they prepared a permanent emulsion from the nano soap. Then, the emulsion was added to gasoline in different amounts, and the pollution test was carried out for the emitted gases. The results show that applying nano choline stearate as an oxidizing compound with a high cleaning capacity results in an average decrease of 30-50% of the two important pollutants (CO & HC) depending on the type of automobile and the amount of emulsion used in its fuel; however, it does not have any positive effect on an increase or decrease in the amount of NOX.

Various soil and water remediation techniques including the use of chemical amendments have been applied to reduce the risks associated with these contaminants. This paper reviews the use of chemical amendments for immobilizing chemical amendments, the chemistry of contaminant immobilization, and environmental concerns associated with the use of these products. Total Contents of heavy metal in the soils of polluted villages of Hashtrood city and determining the relationships of these metals and soil properties are the goals of this research.Material and Methodology: The commonly used chemical amendments were grouped into aluminum-, calcium-, and iron-containing products. Other products of interest include phosphorus-containing compounds and silicate clays.Results: Mechanisms of contaminant immobilization include one or a combination of the following: surface precipitation, adsorption to mineral surfaces (ion exchange and formation of stable complexes), precipitation as salts, and co-precipitation. Reviews of environmental implications revealed that undesirable substances such as trace elements, fluoride, sulfate, total dissolved solids, as well as radioactive materials associated with some industrial wastes used as amendment could be leached to ground water or lost through run off to receiving water bodies.Discussion and Conclusion: The acidity or alkalinity associated with some of the industrial-waste amendments could also constitute a substantial environmental hazard. Chemical amendments have elements capable of affecting the activities of certain microbes that could influence geochemical processes such as mineral dissolution and formation, weathering, and organic matter mineralization.

Glucose oxidase is an oxido-reductase enzyme that catalyses the oxidation of glucose to hydrogen peroxide and gluconic acid. In this study, the glucose oxidase enzyme, its structure and function, tragacanth polymer, different methods of enzyme immobilization and statistical modeling methods have been introduced. To investigate the enzyme activity of glucose oxidase using design of experiments (DOE) and response surface methodology (RSM), the results of 19 experiments, have been conducted in previous research, were used. For modeling and optimization of enzymatic activity, three variables of pH, temperature and immobilization time were selected and examined using the Design Expert software. Then, based on statistical modeling, a correlation was proposed that be able to determine the enzyme activity of the glucose oxidase. Using response surface methodology, maximum enzyme activity (1116.2 μmol/min) of the glucose oxidase was achieved at pH of 5.98, 37 ° C and 33.28 minutes. Finally we observed that our model results are accurately agreed with the experimental results. Manuscript profile -

Bio MoreNowadays demands for clean power source enhanced. Bio-fuel cell (BFC) can convert chemical energy to electrical energy. The enzyme-based biofuel cell (BFC) is a special fuel cell using enzyme as catalyst and can directly convert chemical energy to electrical energy. Bio-fuel cells are energy conversion devices based on bio-electrocatalysis leveraging on enzymes or microorganisms. Enzymatic fuel cells are promising low cost, compact and flexible energy resources. The basis of enzymatic fuel cells is transfer of electron from enzyme to the electrode surface and vice versa.. The DET of laccase enzyme has been studied using Multi-walled carbon nanotubes (MWCNTs)/Nafion polymer. Laccase was entrapped by nafion polymer . As Nafion is a proton exchange polymer but not an electron conductive, the MWCNTs were also used to facilitate electron transfer of laccase. Cyclic voltammetric results showed a well-defined redox peaks at 170 µA in a solution containing 10 µM o-dianisidine as a substrate for MWCNTs/Nafion composite. The cyclic voltammetric results showed that laccase immobilization on MWCNTs/Nafion is efficient. Therefore, this method can be used to fabricate biocathode of biofuels cellor laccase based biosensors. Manuscript profile -

Therefore, the purpose of this study was to investigate the effect of aromatherapy with ginger EO on serum metabolites and fear related responses in capons and intact cockerels. Materials and Methods:In this study, 10 caponized and 10 sham-operatedcockerelswere used. Half of the poultries in each group (capons=5 andsham-operated cockerels=5) were treated by aromatic EO in a chamber, and the rest of experimental poultries were exposed to water vapor in the same chamber. Eachbird after removal from the chamber was held by both legs and swung into an inverted position for 30 s and thereaftertonic immobility (TI)test was performed on it.Two weeks after this test, the aromatherapy process was repeated in all birds and blood plasma metabolites were measured before and after aromatherapy. Results: Aromatherapy in the caponized group resulted in a decrease in the tonic immobility duration, indicating a decrease in fearfulness induced by harvesting process.Moreover, aromatherapy significantly increased plasmalevels of glucose, protein and total urea in cockerels. Conclusion: Aromatherapy is probably by activating the sympathetic system and increase blood pressure, lead to increased levels of glucose, protein and serum urea and reduce the number of inductions required to attain the TI response. Therefore, ginger EOexposure during manual harvesting maybe advisable to reduce fearful responses in cockerels. Manuscript profile -

And sports clubs need to be analyzed and read from the perspective of the fans. Therefore, the purpose of the current research is to analyze the lived experience of fans of the challenges of developing the culture of football fandom.Methodology: Qualitative research method is a phenomenological type with a descriptive approach and based on the Colaizzi model. The research community was the members of Sepahan Isfahan Sports Club and the cultural managers of the club. Of these, the research sample reached data saturation with 20 people. The purposeful sampling method was dependent on the criteria and heterogeneous. The data collection tool was a semi-structured interview. The validity of the data was confirmed through external auditors, in-depth description, returning to the interviewees and two coders.Results: The findings of the research after implementing the information and coding the data in several categories including the re-engineering of the fans' thoughts in the development culture, the increasing trend towards media consumption, instrumental attitude towards the fans, the feminization of sports, the social responsibility of the fans, the cultural-social competence of the fans and Fan businesses were categorized.Conclusion: The development of fan culture requires preparation to face challenges, a major part of which can be done by increasing individual and interpersonal skills by fans; the results of this research will be effective in strengthening and rebuilding the attitudes of the managers and planners of fan centers for the development of fan culture.Paying attention to the upcoming challenges of the fan culture requires sports centers to create the necessary frameworks and standards to attract, educate and promote the fan culture and modify the existing processes in order to support the development of fandom. Based on this, fan centers need to draw a technical and cultural map in order to reach the desired sports position with the aim of continuing the presence of fans through the expansion and development of entrepreneurship and value creation of sports at the community level.

Nitrogen factor with two levels of non-foliar application (N1) and application of urea fertilizer 46% in the flowering stage at a rate of 20 kg / ha (N2) were allotted to the main plots and cereal type factor in the subplots. The results showed that N2 treatment increased grain yield by 12.6%, which was mainly due to the increase in the contribution of current photosynthesis in grain yield formation from 43.6 to 51.2% and had little relationship with the efficiency of dry matter distribution to grain. Also, N2 treatment, despite a significant reduction in 1000-seed weight, increased the number of seeds per spike by 20.9% and grain weight per spike by 12.9%. Nitrogen foliar application increased the contribution of current photosynthesis in grain yield formation from 43.6% to 51.2% and decreased the rule of stem dry matter remobilization in yield formation from 72.4% to 53.4%. Despite having the same harvest index as wheat, triticale had 13.3% higher grain yield than wheat due to its higher biological yield. The amount of current photosynthesis in triticale was %46.8 more than wheat, but the relative contribution of stem reserves to yield formation was not significantly different. The main reason for the higher in triticale compared to wheat was the higher number of grains per spike, and the difference in grain weight was less important. The results indicate that grain weight is not affected by nitrogen uptake and transport processes and is mostly a function of photosynthesis. Based on these results, the source-sink balance in triticale resulted in higher yield of it compared to wheat and barley. It seems that nitrogen in the flowering stage can increase the yield of wheat and barley by preventing abortion of florets and increasing the size of the reservoir as well as improving the strength of the source by increasing the current photosynthesis.

Due to the fact that the amylase gene of Bacillus alkalitelluris has not been identified so far, it is important to achieve stable enzyme production conditions by the bacteria that produce these enzymes. One of the most important methods is to immobilization of the bacteria in suitable support so that the ability of these bacteria to produce enzymes is maintained. In this study, Bacillus alkalitelluris was first cultured in LB broth culture medium containing starch. The bacteria were then immobolized on agar and the amount of enzyme produced was measured using the DNS method. Finally, the amount of enzyme production when re-use stabilized cells in successive cultures was evaluated. According to the results, the bacterium Bacillus alkalitelluris immobilized in agar support is still able to produce alpha-amylase enzyme. Maximum alpha-amylase production was obtained after 24 hours. In addition, the immobilized bacteria remain after 4 times of changing the culture medium and are able to produce amylase enzyme so that up to 72 hours no significant change in enzyme production is observed. Due to the fact that the immobilized of Bacillus alkalitelluris in agar leads to the maintenance of alpha-amylase production capacity, so this method can be used in mass production of amylase enzyme.

With the advancement of technology, new enzymes with a wide range of applications and properties have been developed, and new fields of application are still being investigated. Microorganisms such as bacteria, yeasts, and fungi and their enzymes are widely used in many foods to improve flavor and texture and have many economic benefits for industries. Enzymes are also able to remove organic substances from food wastes effectively. Microbial enzymes are preferred sources over plants or animals due to their many advantages such as easy production, cost-effectiveness, and compatibility. However, the use of enzymes in processes has a series of disadvantages. Due to the high price of enzymes, enzymatic processes are one of the most expensive reactions. They are also sensitive to environmental conditions and can easily change their nature and lose their properties. Using a heterogeneous catalyst and immobilized enzymes on a solid support is a method that can make the recycling of enzymes possible. In this research, after examining the structure and types of enzymes, the thermodynamics of enzyme reactions and methods of enzyme stabilization were studied. Finally, recent advances in enzyme technology for food industries and a comprehensive list of enzymes used in food processing, the microbial source of these enzymes, and their wide range of applications are discussed.

Hence, MoreIn order to obtain an optimum economical system in our country, there is a call to choose the shortest and fastest path for achieving the goal. The system can only achieve this goal, when it could obtain the best and maximum outputs by spending the least inputs. Hence, there is only one way ahead, which is the way of productivity. Among different areas of productivities, human resource productivity plays one of the most significant roles in the whole system productivity because the human resource is the provider of the capital. Hence, the lack of human resources reflects itself as capital demand and economical dependency. The present paper, based on the investigation carried out on the country industry and by considering the impact of computer on the level of human resource productivity in the administrative section, has been attempted to determine the drawbacks of the system. In order to successfully determine the drawbacks, the parameters such as the conditions of securing a job vacancy regarding to the level of computer literacy of the personnel, the speed of fulfilling a task using computers and the condition of the job, the security of computer utilization, the level of output yield from investing in computer utilization and the level of satisfaction from computer utilization, has been taken into account. The mentioned parameters have been ranked according to their maladjustment with computer utilization, from personnel and managers point of view. Consequently, in order to remove these drawbacks and increase human resource productivity, some solutions are presented. For conducting this research, several automobile industries as the investigating cases have been chosen randomly. The final analysis by information collection and data statistical surveys has been carried out and then the outcomes are presented. Manuscript profile -

Considering the effects of Anthemis nobilis L. in traditional medicine as an effective treatment of certain diseases, the aim of this study was to evaluate the effect of hydro-alcoholic extract of Anthemis nobilis L.onreproductive and behavioural parameters in male rats exposed to immobility stress. Thirty male Wistar rats weighing 220±20 g were randomly divided into five groups including control without any stress and additive, control exposed to stress without additive (positive control) and treatment groups exposed to stress and receiving Anthemis nobilis L.extract in dosages of 50, 100 and 200mg/kg respectively. The extract was given to the rats with gavage and accompanied by immobility stress for 21 days. At the end of the study, anxiety was evaluated using elevated plus maze, also blood samples were collected for hormonal assay and the number of sperms were assessed. Obtained data were analyzed using one way ANOVA followed by Tukey post hoc test. Hydro-alcoholic extract of Anthemis nobilis L.significantly increased the number of sperms, testosterone, LH and FSH levels in comparison to the stress group (p < /em><0.05). Also the findings of this research revealed that the extract led to significant increase in percentages of open arm entry and decrease in percentages of close arm entries in the elevated plus maze compared to the stress group (p < /em><0.05). The results indicated that hydro alcoholic extract of Anthemis nobilis L.has anxiolytic effects and increases the reproductive parameters probably due to antioxidant components of this plant.

Via a rich literature review, the factors involved in the formation of teleworking were added to the conceptual model and their congruence with the Iranian organizations were measured through two stages of pragmatic and scientific talent via the Delphi technique. The telework industry indicators were determined via a questionnaire that was administered to a snowball sample selected from the population of experienced teleworkers, teleworker managers, and the scientific community that is normally associated with teleworking. Comparison of the similarity of each aspect of the factors with types of organizational cultures supported the similarity among them. The research data were analyzed using SPSS software and the Multidimensional Scaling Technology rendering four types of teleworking based on the distance matrix and determining the coordinates of each of the indicators on the dimensions of the model of competitive values model (control dimension - flexibility and focus on intraocularization outside the organization). The results showed that organizational culture significantly influences the way teleworking works, and that teleworking is a multi-dimensional structure whose precise execution depends on the context. This implies the necessity of telecommunication modalities to be implemented in order to take advantage of the organization from an ecological point of view. Manuscript profile -

The proposed model is a combination of GMS aquifer simulation model and Billiard-Inspired Multi-Objective Optimization Algorithm (MOBOA) in MATLAB programming. First, the model was calibrated and validated to determine the hydrodynamic parameters of the aquifer. Then, by minimizing the three deficit objective functions comprises as the shortage affected by the failure to supply water demands, groundwater level drop and Modified Shortage Index (MSI), the model was implemented for a period of one year with 12 periods of monthly stress and the Pareto front was achieved. As one of Pareto optimal calculated responses, it can be observed that when groundwater level remains unchanged, 11.7 million cubic meters of demands will be in short supply and the amount of MSI will be 17.15. In order to specify the best option of operation policy, considering the socio-economic criteria as well as environmental consequences by the relevant officials, it is essential to select the suitable optimal response from the other Pareto optimal solutions and the corresponding withdrawal values will be determined. By studying the consequences of applying the proposed structure, it is worth noting that the proposed procedure has a high efficiency in determining the optimal aquifer strategy. Manuscript profile -

The main factor of drought stress at the end of the season with two levels of normal irrigation and cessation of irrigation in the post-pollination stage, cycocel with three levels of water as a control, 1.5 g/l, and 3 g/l, and humic acid with three levels of non-foliar application (water as control), 2 liters per hectare, and 4 liters per hectare were factorial sub-factors. Results showed that the interaction of end-of-the-season drought stress and cycocel on grain yield and number of grains per spike was significant. The highest grain yield (4840.5 kg ha-1) was obtained by applying 3 g/l cycocel under normal irrigation conditions, which did not show a statistically significant difference from the application of 3 g/l cycocel under drought stress at the end of the season. Application of humic acid had a positive and significant effect on all test traits. The highest grain yield, number of grains per spike, and 1000-grain weight were obtained from the application of 3 liters per hectare of humic acid under normal irrigation conditions. Under end-of-the season drought stress, the current photosynthesis and the share of current photosynthesis decreased by 29% and 10%, respectively while remobilization and contribution of remobilization increased by 16% and 34%, respectively. In general, to increase the rate of grain yield under optimal conditions and reduce the drop in stress conditions, growth regulators such as cycocel by a concentration of 3 g/l and organic acid fertilizer by the concentration of 4 liters per hectare are recommended.

In this paper, thetrajectory tracking control issues of a tractor-trailer wheeled mob­ile robot has been significantly solved in the presence of structural uncertainties,non-hol­o­­n­o­mic constraints and external disturbance. The proposed scheme is based on a design that the tractor-trailer’s state space representation is extracted from its dynamic and ki­n­­e­matic models and presented ina companion format first. In the following,by considering the state space representation of system, the control algorithm is presented includingtwo external and internal control loops. Toward this end, the control law has been developed in the inner loop via input-output feedback linearization in a nonlinear feedback formwh­i­­ch is continuously eliminating the nonlinear dynamics of the system. Then,by using a comb­ination of the output that is pr­o­duced in linearization steps with a terminal sliding mode control algorithm and sketching a neural robust ad­aptive finite time controller in the outer loop, the accurate and fast performance of the closed loop system has been guar­a­nteed in the presence of uncertainties. The proposed control algorithmfinally guarantees the boundedness of closed-loop signals and accurate finite time convergence of tracking errors. At the end, the effectiveness of the proposed sch­eme has been demo­nstrated and shown through the extended Lyapunov theorem and simulated by MATLAB application. Manuscript profile -

Also, optimizing the path length and crossing the local minima traps are the basic and up-to-date challenges in this field. One of the important methods in path planning of these robots is the artificial potential field method. Because it is based on simple mathematical calculations. One of the most important disadvantages of this method is getting trapped in local minima situations. One approach for solving the problem of local minima is to use optimization methods to find suitable coefficients (attractive and repulsive) and step length that can solve local minima and optimize the path length. The Harris Hawks algorithm is a powerful and new meta-heuristic algorithm in the field of optimization that is based on population and inspired by the life of Harris Hawks in nature. This algorithm has been able to prove its superiority over similar optimization methods in finding the optimal solution, faster convergence, lower computational time and not trapping in local minima. This method has not been used in the path planning of mobile robots. In order to eliminate the disadvantages of the artificial potential field method and to optimize the path length, the Harris Hawks algorithm has been used in this paper. The simulation results showed that the combination of the artificial potential field method and the Harris Hawks algorithm can solve the local minima problem and optimize the path length, increase the path efficiency and reduce the convergence time.

To reduce the data transfer time in the relay node selection criteria, we consider the effect of different factors: node records, end-to-end latency, the nodes' available buffer space, and information such as average speed and node movement direction. We also use artificial intelligence to perform optimal routing using the Simulated Annealing algorithm. Important common performance criteria such as average latency, delivery ratio, number of lost messages, and network overhead were used to evaluate the performance of the proposed model. The results showed that our proposed routing method has less reception delay than other routing methods and maintains maximum transmission. Manuscript profile -

Robot models include kinematic and dynamic equations of motion. In this paper, in order to reach the final position, the wheeled moving robot must be controlled in such a way that it can follow a reference path. Many studies often use a motion control strategy for the wheeled mobile robot. In this study, the proposed control strategy has two stages including cinematic control and dynamic control. In this regard, first after introducing the kinematic model of the robot, we design a predictive controller for this part and prove it. Then, based on the nonlinear dynamic dynamics of the robot, an adaptive sliding mode dynamic controller is introduced to estimate the disturbances online, automatically adjust the gain of the control and eliminate the umbrella phenomenon completely. Then, the proposed design is analyzed and proved using Lyapanov's theory of stability. According to the proposed adaptive control law, optimal convergence and tracking performance of all signals are guaranteed and tracking errors can converge arbitrarily in finite time to the source. Simulation results have been performed to show the effectiveness of the proposed design using Matlab software. Manuscript profile -

The proposed scheme minimizes the planning cost (including construction, maintenance, and operation) of the mentioned sources and storages, and environmental pollution level. This problem is constrained to operation and planning model of the different sources and storages, and power balance constraint in IHS. The proposed scheme is formulated in the Pareto optimization framework based on method of the summation of weighted functions. Also, the bounded uncertainty-based robust optimization (BURO) is used to model the uncertainties of load, renewable power, and energy of mobile storage. Then, the hybrid evolutionary algorithm according to composition of Krill Herd Optimization (KHO) and Grey Wolf Optimization (GWO) algorithms obtains an optimal solution including low standard deviation in the final response. Finally, it is seen that the proposed scheme has a suitable capability in the planning of the proposed system according to economic and environmental viewpoints based on obtained numerical results.

Each of the generated passbands, is resonated by the use of one of the two existing types of resonator structures. The larger resonators, as main-structures of the filter with a stepped-impedance features, by appling 0°-feed structure and electrical coupling in-between, create the first passband at 0.9 GHz. The smaller resonators as sub-structures, with dual-spiral topology, are in the same size and uniform-impedance, and with symmetrical feeding and internal coupling, are embedded in the main-structures to generate and control the higher passband at 1.8GHz. The existence of a cross-coupling between the sub-structures, suppresses any harmonics in the stop-band and generates additional transmission zeros on both sides of the upper passband. Overal dimensions of the innovative filters with a miniaturizing approach, are reduced from 0.163λg*0.09λg to 0.092λg*0.08λg in terms of the guided wavelength, which is the most compacted structure compared with other filters. According to 0.7 dB and 0.5 dB, the obtained insertion losses of the first and second passbands of the dual-band BPF respectively, the lowest losses have been achieved, compared with other examined dual-band BPFs. Finally three prototypes for global systems for mobile communication, were fabricated and measured. A good agreement between the measured and simulated results indicates realizing the goals and ingenious methods of this design. Manuscript profile -

In this paper, a new global path planning algorithm named HYBRID-Visibility-QuadTree-Voronoi-WaveFront method (HYBRID-VQVW) is presented where these four methods are integrated in a single architecture. After constructing these global trajectories of C-space, the best trajectory among four is selected in every sampling distance by several criterions. These criterions consist of length, smoothness and safety of the trajectory. In fact, the algorithm provides a parametric tradeoff between shortest, safest and smoothest paths and generally yields shorter and smoother paths than the Voronoi, Quad-Tree and Wave-Front methods, and safer than the visibility graph.

VANETs address direct communication between vehicle-to-vehicle and vehicles to roadside units (RSUs). They are similar to the Mobile and Ad hoc Networks (MANET) in their rapid and dynamic network topology changes due to the fast motion of nodes. High mobility of nodes and network resources limitations have made the routing, one of the most important challenges in VANET researches. Therefore, guaranteeing a stable and reliable routing algorithm over VANET is one of the main steps to realize an effective vehicular communications. In this paper, a two-step AODV-based routing protocol is proposed for VANET networks. At first, node-grouping is done using their mobility information such as speed and movement direction. If the first step cannot respond efficiently, the algorithm enters the second step which uses link expiration time (LET) information in the formation of the groups. The goal of the proposed protocol is increasing the stability of routing algorithm by selecting long-lived routes and decreasing link breakages. The comparison of proposed algorithm with AODV and DSR protocols is performed via the Network Simulator NS-2. It is shown that the proposed algorithm increases the delivery ratio and also decreases the routing control overhead. Manuscript profile -

The article tries to base its argument on the theory of “uneven development” of Samuel Huntington. A theory which believes that once the political institution lag behind the social and economic transformation this phenomenon leads to creation of new foundation for political association and formation of new political institutions. The underlying hypothesis is that the uneven development of Hashemi period (Reconstruction period) was the cause of Khatami coming into power. In fact due to social and class mobility along with economic development and consequently the growth of new middle class which happened during this period new expectations and demands were created which were mainly participation in the country’s affairs and determining their political future. But during this period no tangible effort were made to fulfill these demands for political development. In this background the slogans of Khatami which were based on the above said demands led to this fact that a large section of voters cast their votes in favour of Khatami and this culminated to his victory in the seventh presidential elections.

Our investigation sought to illuminate the educational and learning contexts, methodologies, data collection techniques, learning outcomes, and challenges associated with M-TBLL. To this end, we meticulously combed through the ISI Web of Science database, ultimately analyzing 50 carefully selected papers from a pool of 398 identified publications. The review yielded several key findings. First, all included studies focused on language learning, demonstrating the versatility of M-TBLL across various linguistic domains. Second, a clear trend emerged toward higher education settings as the primary research ground for M-TBLL, highlighting its potential for advanced language acquisition. Moreover, the review revealed a growing emphasis on informal learning contexts, suggesting a shift towards mobile technology facilitating language learning beyond the traditional classroom walls. In-depth empirical studies on mobile seamless learning could shed light on the integration of mobile devices into existing learning environments. Additionally, research into tasks specifically designed based on learners' needs analyses could personalize and optimize the M-TBLL experience. Finally, investigations into cognitive load and learning anxiety in M-TBLL contexts could offer valuable insights into mitigating student stress and maximizing learning potential. By addressing these gaps and embracing emerging trends, future research can continue to shape and refine the landscape of M-TBLL, unlocking its full potential for enhancing language acquisition in diverse educational settings.

The research was conducted using qualitative approach, grounded theory method and the paradigmatic model. Data analysis was performed using the continuous comparative method of Strauss and Corbin. Unstructured, in-depth interviews were conducted individually, and the duration of each interview session was between 1-2 hours. 15 interviews were conducted. 67 concepts were formed and 21 categories were created. Interviewees were selected via a snowball sampling method. In this study, triangulation validity was used. The results showed that the modern identity was acquired through exclusion of the adult woman, psychological and mental preoccupations, and compliance with social demands. Factors affecting the acquisition of modern identity were identified as body-dysmorphic-disorder, the desire to reach the era of beauty and dreaming of the ideal body. Advancement of technology, people's encouragement and public acceptance were the intervening conditions and the acquisition of modern identity lead to imitating of media and reference groups and a search for beauty surgeons and hair stylits. The consequences of such actions and responses are addiction and dependency to makeup, showing the vertical mobility of social classes, showing good taste and creativity to others, and the spreading of a culture of consumption.

Hence, the prevalence of COVID-19 led to more emphasis on the role and importance of smart cities in dealing with and preventing crises. Because it combines the capabilities of the real and virtual world to solve urban problems. Therefore, the purpose of this study was to identify smart city indicators for reducing the COVID-19 risk. The present study is a descriptive-correlational and applied study that has been conducted using exploratory factor analysis with principal component analysis. The statistical population of this study is citizens living in the new town of Baharestan. Using available sampling method, 382 people were selected as sample members. The main tool for collecting information was a questionnaire. Descriptive and inferential statistics were used to analyze the obtained data. Findings from exploratory factor analysis led to the identification of three factors: smart services, smart health care and smart mobility. smart cities with the above three factors, have the ability to reduce the risk of corona and can play an important role in the optimal control and management of the situation in the event of such crises. Building smarter cities can support significantly better outbreaks and are crucial to saving lives. Evidence suggests that the risk of COVID-19 can be reduced with the help of smart city solutions. The need for smart cities is essential for the epidemic. COVID-19 epidemic has increased the demand for smart city and justified its existence. Manuscript profile -

The aim of this study was to identify behaviors, demographic, social and economic migrants in the southern regions and less developed Afghanistan Iran. Afghan refugees in Iran of significant population (4.1 million) and long-term record of their presence in society, the need to study in the field of recognizing the different characteristics of this group of immigrants stresses. So the two regions in the provinces of Fars and Hormozgan (Parsian and Lamerd) selected from 115 women 15 to 49, the information collected and analyzed. The findings suggest that immigrant women's reproductive and fertility of origin and destination are significant differences in the level of the target provinces. Among the social variables explained only education gives women of reproductive differences. A significant correlation between length of stay, there was no family relationship of spouses and children. Low levels of awareness and early marriage leads to a lack of social mobility of immigrant women. These two factors lead to higher fertility levels were to immigrant women than women. It seems that there are areas of cultural and religious, such as early marriage, particularly for girls, called sons of immigrants in the city studied the determinants of reproductive behavior in the coming years and their fertility at a higher level than natives place.

The problem in these networks is the non-rechargeable batteries of these sensors, which limit the lifetime of the network. Therefore, the optimal energy consumption of sensors is an open research topic. In this paper, a new algorithm with the Development of Genetic Algorithm with the Floyd Warshall (DGAFW) has been proposed. Using the proposed DGAFW algorithm, the number of clusters and nodes assigned to each cluster is first determined with the Floyd Warshall algorithm and then the Cluster Head (CH) is selected using fuzzy logic. Finally, the optimal placement of the base station is specified by the combination of the Genetic Algorithm and the Floyd Warshall. The DGAFW algorithm is based on minimizing the distance of sending multi-hop messages. The simulation is carried out in MATLAB 2023a online software. The simulation results obtained from the DGAFW algorithm have been compared based on the distance, the amount of remaining energy in each round, and the number of rounds of network activity in the case where the location of the base station is fixed or randomly determined in each round. The results obtained show that the DGAFW algorithm compared to the case of random base station and fixed station respectively, has 12.7% and 14.3% shorter average message-sending distance in each round, 14.7% and 19.1% more residual energy and also 36% and 48% more rounds of network activity.

Effective parameters of the method such as pH, ionic strength of the sample, homogenization rate and time, type and volume of extraction solvent have been investigated and optimized. Optimal conditions were obtained by applying 50 µl chloroform solvent at 8 second homogenization time for 16000 rpm at pH equal to 5 and salt addition at 0.15 g/ml. The analytical performances of the method including linear range, detection limit, repeatability, and enrichment factor were evaluated under optimal conditions. The calibration curve was linear in the range of 10 to 500 μg/L. The inter-day and intra-day relative standard deviations were 9.8% and 8.1%, respectively. The limit of detection for the analyte was 3.1 µg/L. Relative recoveries were obtained in the range of 92 to 111% for river water, 88 to 107% for urine, and 92 to 106% for milk samples.

It was found that in the presence of hydronium as reactant ion and ammonium as dopant, the ionization of valine took place through its protonation, fragmentation of protonated molecule, and also formation of adduct ions. At least six ionic species were identified as product. In ion mobility spectrum of valine, two signals were assigned to the protonated valine and its symmetric proton-bound dimer, respectively. Identification of two other signals were conducted by comparison of the ion mobility spectrum of valine and isobutylamine. Using mass-mobility correlation equation based on two standard masses, two other signals were assigned. One of them was attributed to an ionic cluster obtained from the interaction of the ionic fragment with the neutral molecule of valine and the other one was related to a carbocation resulting from the fragmentation of protonated valine through the elimination of water. By the study of time, evolution of product and reactant ions signals and also the change of cell temperature, the proposed origin of the signals was confirmed. Therefore, the identification of ion products without need to couple the ion mobility spectrometer to the mass spectrometer was performed. Manuscript profile -

Thus, the development of an efficient amidation method continues to be an essential scientific pursuit. In this research, a simple method was introduced for the direct and solvent-free formation of amides, and also for real-time product identification. At first, the ion mobility spectrum of perindopril erbumine salt was obtained, and the ionic species resulting from evaporation and ionization of this salt in corona discharge were identified. Subsequently, the formation of a product ion having heavier mass than protonated perindopril was demonstrated by applying thermal shock at 400 °C to perindopril erbumine salt. The variation of the intensities of the peaks in the ion mobility spectra over the elapsed time, and also predicting the mass of the ionic species were examined to determine the nature of the newly formed product. Through the method described in this article the new product was identified to be an amide compound. The efficiency of the two-reference method for applying the mass-mobility correlation equation to predict the masses of ion species in the ion mobility spectrometry was demonstrated. The results of this study showed that applying thermal shock to perindopril erbumine in addition to degradation of the sample can cause to create new products through the formation of amide bond.

The proposed method is based on using a smartphone to obtain RGB values of digital images. 4-nitroaniline and α-naphthol were used to convert nitrite to a colored product. Magnetic solid phase extraction was then used to extract azo dye. In magnetic solid phase extraction, magnetic graphene was used as adsorbent and acetone as a desorption solvent. After taking the extraction phase digital images using a cell phone and their analyzing using Color Grab software, R values were used to obtain analysis signal related to nitrite concentration. The experimental parameters affecting the reaction and extraction efficiency were investigated. Under optimum conditions, the detection limit and the quantitative limit of the method were obtained 1.2 and 4 μg l-1, respectively. The calibration graph was linear in the range of 10-300 μg l-1 with a correlation coefficient of 0.993. The relative standard deviations for 100 and 30 μg l-1 were 2.2 and 3.9, respectively. The proposed method was successfully applied for the determination of nitrite in various water samples. Manuscript profile -

Robot models include kinematic and dynamic equations of motion. A barrier function adaptive terminal sliding mode control is used to control the movement of the robot. It considers sliding mode control (SMC) to deal with the dynamic model uncertainties of the chaos system, and uses a combination of SMC with an adaptive control approach to solve the upper boundaries problem of unknown model uncertainties and their estimation. Chattering is completely eliminated without over estimating the control gains by adopting an adaptive continuous barrier function in the dynamic switching function. Using the Lyapunov's stability theory, it was shown that the proposed scheme can guarantee the convergence of system states to the vicinity of the sliding surface in finite time. Additionally, the adoption of a sliding surface with a nonlinear and integral switching function resulted in removing the reaching phase of the sliding surface and yielding a controller that is robust to uncertainties from the start. The effectiveness of the proposed control method was assessed using three scenarios implemented to a Liu's uncertain chaotic system in MATLAB/Simulink environment. The obtained results confirmed the ability of the proposed approach to achieve continuous and smooth control rules for such chaotic systems. Among the main attributes of the proposed control method are its ability to completely eliminate chattering and yield a robust performance against model uncertainties and unknown external disturbances.

Cells immobilization is a useful method for protecting microorganisms against direct physicochemical tensions and reusing them. This study was conducted to assess the effect of alginate-chitosan complex carrier on immobilizing Saccharomyces cerevisiae in order to enhance the yield of ethanol production in the presence of furfural. Methods & Materials: In this study, S. cerevisiae AT-1350 were immobilized in alginate-chitosan complex carrier. Then, 3 g/L of furfural was added to the fermentation medium as the stressor. Glucose consumption was determined using glucose sensing kit. High performance liquid chromatography was used to measure the amount of ethanol production. Results: The results showed that the ethanol yield was decreased 21% by non-immobilized autochthonous yeast, in the medium containing 3 g/L furfural as compared to the control (furfural-free medium). On the other hand, in the presence of furfural, using yeast immobilized in alginate-chitosan complex increased the ethanol yield 6.9% and 14.4% in comparison with yeasts immobilized in alginate and non-immobilized yeasts, respectively. Conclusion: The alginate-chitosan complex can be used as a suitable carrier to immobilize and protect yeast cells against tensions and thusto enhance the ethanol yield obtained from lignocellulosic wastes.

For instance, application of the antimicrobial activity of nanosilver is one of the consequences of such these strategies. Furthermore, iron oxide nanoparticles is currently employed in microbial cell fixation. In addition, nanoparticles can be used for effective targeted drug delivery to the site of infection. In this term, study on the effect of iron oxide nanoparticles on the physiology of microorganisms is highly demanded. At low concentrations, since iron oxide nanoparticles can act as iron source of microorganisms, they may be eliminated from microbial environment. However, higher concentrations of these particles can result in cell stress and reduction in microbial cell growth. These nanoparticles attach to the microbial cell wall via electrostatic and hydrophobic forces, reducing microbial pathogenicity. The attachment of iron oxide nanoparticles to bacterial cell wall interferes in functionality of cell membrane and thereby increase membranes permeability. These phenomenon increases molecular transportation through the cell membrane and increases productivity in industrial process. Manuscript profile -

The aim of this study was to immobilize Bacillus licheniformis cells in calcium alginate beads and study of its effects on the amount of alkaline protease production. Effects of several different conditions on stability of the beads were also examined. Material and Methods: Bacillus licheniformis cells were immobilized in calcium alginate beads and were used for production of alkaline protease. The amount of enzyme production was compared in immobilized and free-cell fermentation. Effect of stuffing rate (%) on the enzyme production was studied. Optimum pH and temperature of enzyme activity were also determined. Furthermore, effects of pH, curing time and treating the beads by glutaraldehyde on stability of the beads were examined. Results: In this study the amount of production and productivity of protease in immobilized cells state showed an increase of 74% and 54% in comparison to free cells state, respectively. The highest amount of the production of the enzyme was obtained in stuffing rate of 5% (v/v). Optimum pH and temperature of the enzyme activity were determined 8 and 65oC, respectively. The highest stability of the beads was observed at curing time of 1 hour at pH of 7.4. Treating the beads by glutaraldehyde was detrimental to their stability. Conclusion: Use of immobilized cells of Bacillus licheniformis in calcium alginate beads on the one hand, can increase productivity of the alkaline protease in comparison to free cells method, and on the other hand, reduces the cost of the enzyme production because of eliminating the need of preparation of inoculum for the new batches.

In this study interfering effects of two distinguished plant extracts, whitetop and dill, on bacterial quorum sensing of Chromobacterium violaceum CV026 was evaluated. Materials and Methods: Whitetop and dill plant species were collected from the surrounding agricultural areas and commercial fields of Urmia City. The collected plants were extracted using three organic solvents, 96% ethanol, n-hexane and methanol. The Antimicrobial susceptibility and anti-quorum sensing bioassays were then performed to find out their bactericidal property and depletion of violacein, respectively. Furthermore, the assays regarding pathogenicity suppression using anti-quorum sensing activity and acyl homoserine lactone induction through Pectobacterium carotovorum subsp. carotovorum strain were carried out. Results: Based on the results, both of the plant extracts possess meaningful anti-QS activities; however, the proportion of the activity in whitetop was fewer than dill. Furthermore, the aforementioned plant extracts had bactericidal activity in which whitetop had more proportion in comparison to dill. Conclusion: Due to decrease in the production level of violacein by CV026 as a result of the anti-quorum sensing activity of whitetop and dill extracts, application of the extracts can be considered as an appropriate approach for controlling bacterial pathogens without developing resistance.

This study included drought stress as irrigation at different stages of plant growth (V1= withholding irrigation at the beginning of 10 leaves to emerge tassel, V2= withholding irrigation at rise of 50 percent of tassel, until becoming a brown silk, V3= irrigation according to plant requirement until the end of the growing season) as main plot and three levels of nitrogen rate (50, 100, 150 kg N/ha) as sub plots were investigated. The results showed that the grain yield significantly under the influence of stress the lack of moisture. The maximum dry matter remobilization was in the rise of 50 percent of tassel, until becoming a brown silk and increase N fertilizer, dry matter remobilization decreased. Treatment of no water stress (control) and application of 150 kg N/ha with an average of 7.4% has a minimum rate of dry remobilization efficiency. The rise of 50 percent of tassel, until becoming a brown silk treatment, with an average of 29.1% has the maximum contributions of dry matter remobilization in grain yield. Increase the amount of nitrogen was significantly reduced nitrogen agronomic efficiency. Applied moisture and N fertilizer on before flowering stage in the event of water stress at this stage was increased through stimulation of the amount of dry matter remobilization can be prevented to some extent a drastic reduction of grain weight.

Treatments including irrigation regimes (common irrigation, cutting off irrigation at mid-flowering and mid-silique formation stages), P application methods (without P, broadcast and band) and rapeseed cultivars (Sarigol and RGS) were assigned in main plots, sub plots and sub sub plots, respectively. Results showed that cutting of irrigation at common irrigation with 25.31 seed numbers per silique had significant differences with mid-flowering with 22.25 seed numbers per silique and cutting of irrigation at mid-silique formation with 22.94 seed numbers per silique . In cutting of irrigation at mid-flowering and band application of P, RGS had the highest biological yield (12435 hg/ha). Common irrigation had the highest (11.02 kg/ha) and cutting of irrigation at mid-flowering had the lowest (5.95 kg/ha) P absorption amount. Overall, P recovery efficiency in broadcast and band application methods of P was 1.09% and 1.38%, respectively. RGS cultivar compared to Sarigol had maximum grain yield under cutting of irrigation at mid-flowering (3830 kg/ha) and mid-silique formation conditions (5428 kg/ha). RGS had the highest rate of assimilate remobilization under cutting off irrigation at mid-flowering and band application of P and it can prevent a further reduction in grain yield when exposed to late season water shortage.

Water regime (includes: complete irrigation (control) and withholding irrigation from starting grain-filling stage till maturity) and wheat genotype (includes: Marvdasht and Pishtaz cultivars and DN-11 and 336 lines) were placed in main and sub-plots, respectively. Under control and drought stress treatments, DN-11 line and Marvdasht cultivar had the highest and the lowest grain yield. Drought stress significantly increased dry mater and soluble sugars remobilization of peduncle and penultimate internode in all genotypes and in 336 and DN-11 lines respectively. 336 and DN-11 lines significantly had higher capacity of stem reserves for remobilization from stem to the growing grains than Marvdasht cultivar (sensitive to drought stress). Among studied internodes, lower internodes in addition to having higher potential for accumulation of photosynthetic material also had higher remobilization rate than penultimate and the peduncle internodes. The evidence from this study suggests that DN-11 line with lower grain loss under terminal drought stress then had the highest drought stress resistance. Manuscript profile -

A wide range of techniques are available for the removal of metal ions from polluted environments. Each of them has advantages and disadvantages based on simplicity, flexibility, efficiency of processes, cost, technical and maintenance problems. Therefore, easy, effective, economical and environmentally friendly techniques for treatments are needed. Use of organic absorbents is one of the newest and most appropriate cost techniques. In this study, soil was treated with citrus peel as low cost organic immobilizers in order to investigate the time effect on decreasing mobility of Ni and Zn. The soil was artificially contaminated with Ni and Zn in separate containers. Both elements were incorporated at a dose of 600 mg l-1 and then citrus peel was added to soils at the rate of 5%. Sampling of treatments was in 1h, 1, 3, 7, 14, 21, 28 days of incubation. The experiment was done with 2 treatments including polluted soil samples with and without citrus peel as control in completely randomized design. Statistical analysis done using the SAS software (version 9.1) and Duncan test was performed at 5% level. Results indicated that at the first time of incubation, the pH of soils decreased due to the presence of citrus peel and increased the availability of metals. But the prolonged incubation time led to increasing metal adsorption onto organic adsorbent surfaces and decreasing the metal concentration in exchangeable fraction. Mean Zn concentrations in the control soil and soil treated with citrus peel, were 107.8 and 98.3 mg kg-1 and mean Ni concentrations were 144.5 and 134.4 mg kg,-1 respectively. Differences in control and the citrus peel treatment for both elements were significant. Manuscript profile -

The experiment was carried out in a complete randomized block design with split plot arrangement. The irrigation regimes were allotted to main plots. The intensity and time of defoliation combination were allotted to sub plots. In moderate irrigation plots, the irrigation was done when the soil water content reached to 75% of available water content. In under stress plots, two short periods of water-holding were applied at V8 and tasseling growth stages. Defoliation treatments were consisted of: Control, cutting 1:3 of leaves at V8, cutting of 2:3 of leaves at V8, Cutting 1:3 of leaves at tasseling and cutting 2:3 of leaves at tasseling. This result showed that remobilization efficiency of stem reserves for grain yield is mostly related to sink capacity than source strength. Under moderate irrigation, later or more intensity defoliation decreased the RGR. While under drought stress, cutting the 2/3 of leaves did not decrease the relative growth rate. The improved NAR due to defoliation caused to compensate the decreased leaf area. So, late and more intensity defoliation could not decrease the CGR. The grain yield of 8.9 t ha-1 was attained by moderate irrigation which was a results of 16.4% and 27.3% greater biomass and harvest index compared to the water stress conditions. This indicates that pot-anthesis water deficiency decreased the sink capacity more than source strength. The results showed that under water deficiency and source strength restriction, the stem reserves play an important role in grains filling process. But under high soil water supply, these reserves will be needed when the source strength is limited after flowering stage. Under moderate irrigation, there were not significant differences among defoliation treatment for remobilization efficiency of reserves from stem to grains. Manuscript profile -

Following the progression of this disease, the production of free radicals and inflammatory factors occurs and it is now increasingly widespread, especially among the elderly. Studies show that Bornyl acetate, as a monoterpene, has antioxidant and anti-inflammatory effects. Therefore, the present study aims at assessing the effects of Bornyl acetate on AD male Wistar rats. Aβ1-42 was injected into the hippocampus of male rats bilaterally to create the Alzheimer's model. The therapeutic as well as the preventive effects of Bornyl acetate at a dosage (50, 20 mg/kg) were also investigated. Moreover, biochemical enzymes, SOD and MDA, shuttle box behavioral test, histological studies and hematoxylin & eosin and thioflavin-S staining were used to evaluate neurogenesis and amyloid plaques and the effects of short-term restraint stress on AD rats as well as the effects of the compound in vitro. Biochemical factors, histological images and behavioral test of the AD group were significantly different from the control groups and AD group showed a significant decline in learning and memory indices compared with the control group. Also, receiving a Bornyl acetate caused a significant increase in neurogenesis and a significant decrease in plaque density as well as significant changes in biochemical indices and behavioral tests. In addition, Bornyl acetate + restraint stress (R) group elevated learning speed and improved memory compared with the AD group. Notably, the above combination reduced amyloid fibrils in vitro. It seems that this compound can improve memory disorders and complications according to the results of the present study and previous reports suggest the anti-inflammatory and antioxidant effects of Bornyl acetate.

There is a wide range of indications like infertility with male causes, cervical-associated causes, and unknown causes for intrauterine sperm injection. MoreIntrauterine insemination (IUI) is the first line of infertile couple treatment for its inexpensive and non-invasive. There is a wide range of indications like infertility with male causes, cervical-associated causes, and unknown causes for intrauterine sperm injection. Meanwhile, the main parameters of sperm such as count, mobility, and morphology of sperm play a key role in the success of this method. One of the significant problems in the quality of sperm is the reduced mobility of sperms. Based on the WHO, the mobility under 50%, concentration over 20 million, and morphology over 4% are considered as Astenoaspermia. This study was conducted on the effectiveness of mobility on the outcome of pregnancy with IUI among the infertile couples referring to Jahad Daneshgahi infertility center. A number of 215 samples were divided in three groups of mobility over 70% (normospermia), mobility between 50% and 70% (normospermia) and mobility under 50% (astenoaspermia). The sperms were prepared with SU. The studies indicated that on sperm mobility after preparing had significant increase in all groups. Ovarian stimulations were performed based on the international protocol and the prepared suspension sperm was injected slowly into the uterus with Catheter. The results of pregnancy in term of pregnancy rates, abortion rates, and birth rates were evaluated and analyzed statistically. The results indicated that mobility has no contribution in the significant increase of pregnancy outcomes due to intrauterine insemination. Manuscript profile -

Therefore, it is very important for industry managers to review and improve the acceptance process of these markets. After identifying the factors influencing the acceptance and attractiveness of marketplaces, this study examined the network effect by providing a dynamic model based on bass diffusion theory and modeled and simulated the studied market. This was done by presenting dynamic hypotheses, plotting causal loop diagram (CLD), stock-flow diagram (SFD), and entering mathematical equations in Vensim software. Then, after validating and ensuring the correctness of the model's performance, two different policies were implemented in the model. The research findings show that under the pressure of the Play Store, Iranian markets are still forced to improve their services and at the same time try to reduce the competitive distance with it. These marketplaces need to reconfigure their existing resources and core competencies, given the market dynamics and to gain emerging opportunities. Manuscript profile -

Due to the large volume of reviews, summarizing them is very difficult and error-prone. So far, many works have been done in the field of extractive summarization of users' reviews; However, in most researches, old methods of machine learning or natural language processing have been used, or if a model has been trained for summarizing using transformers, it has not been determined whether this model is useful for summarizing the reviews of mobile users. No? In other words, the model for summarizing texts has been presented in a general purpose form, and no investigation has been carried out for its use in special purpose summarization. In this article, first, 1000 reviews were randomly selected from the Kaggle database of user reviews, and then given to 4 pre-trained models bart_large_cnn, bart_large_xsum, mT5_multilingual_XLSum, and Falcon'sai Text_Summrization for summarization, and the criteria Rouge1, Rouge2 and RoungL were calculated separately for each of the models and finally it was found that the pre-trained Falcon's AI model with a score of 0.6464 in the rouge1 criterion, a score of 0.6140 in the rouge2 criterion and a score of 0.6346 in rougeL The best model for summarizing users' reviews is the Play Store.

Therefore, with the aim of investigating the nitrogen use efficiency and its components in different cereals under the conditions of control (no use nitrogen) and optimal conditions of nitrogen, a factorial field experiment was conducted base on randomized complete block design with three replications at Gonbad Kavus University in 2017-2018. The experimental treatments included cereals at 7 levels, including bread wheat Koohdasht cultivar, durum wheat Seimareh cultivar, two rowed barley Khoram cultivar, six rowed barley Sahra cultivar, hull less barley Line 17, triticale Javanilo cultivar and oat Canadian cultivar) and the nitrogen factor were evaluated at two control (zero) and optimum levels. The result showed that cereal × nitrogen interaction was not significant on nitrogen utilization efficiency, nitrogen uptake efficiency and nitrogen use efficiency, nitrogen harvest index, nitrogen content and grain protein. But the main effect of nitrogen and cereals on nitrogen uptake efficiency, nitrogen utilization efficiency and grain protein percentage was significant at 1% level. While the nitrogen harvest index was only affected by cereals, Also, nitrogen remobilization was affected by cereals, nitrogen and cereals × nitrogen interaction. Finally, the results of this experiment showed that nitrogen use efficiency increased in all studied cereals under optimal nitrogen conditions. Nitrogen use efficiency consists of two components, nitrogen uptake efficiency and nitrogen utilization efficiency, as a result, the increase in nitrogen use efficiency is mostly due to the improvement in nitrogen uptake efficiency. Also, in all cereals under optimal nitrogen conditions, protein percentage and grain yield increased, in order to the increase in protein percentage was due to increased nitrogen remobilization. On the other hand, hull less barley had a higher nitrogen use efficiency than other cereals. Manuscript profile -

The method of this study was a type of descriptive research. The statistical populations of this study were the economic elites in Tehran (about one hundred thousand people) and according to Morgan table, the sample size was 384 people, which was chosen by systematic random selection. In this method, from every 260 people, one person was selected and answered the questioner. To collect the data, the researcher-made questioner was used, the validity of which is determined by content validity, structural validity, and reliability of instruments through Alpha Cronbach formula. In order to analyze the data, one-way ANOVA test, and path analysis method was used. The findings indicate that social mobility was different in the three 70-80-90 decades, regarding vertical, horizontal, and geographic mobility. It was determined that horizontal mobility and geographic mobility in the three 70-80-90 decades had a significant difference. Furthermore, the results showed that economic elites had the most social mobility in the 90 decade, and the least mobility in the 80 decade. Also economic elites in the 90 decade didn’t have the tendency to geographic mobility, because 97,9 percent of the economic elites announced that they didn’t have a tendency to leave the country. Furthermore, it was clear that based on the results, people did not have the tendency toward sufficient mobility. It was also clear in path analysis that the family factor was in the first priority by the sum of direct and indirect effects of 0,291, in the second priority economic knowledge by direct and indirect effects of 0,254, in the third priority media by direct and indirect effects of -0,164 with transition, in the fourth priority, social intelligence by the direct and indirect effects of 0,163 with reverse transition, in the fifth priority, sexual attitude by direct and indirect effects of -0,153 with reverse transition, in the sixth priority, vocal communication by direct and indirect effects of -0,098, in the seventh priority, creativity by direct and indirect effects of -0,90 with transition, and in the eighth priority politics by direct and indirect effects of -0,077 with reverse transition were located.
