Religion is a type of tool for social control that reduces insecurity and increases the feeling of social security by training ethical and normal behaviors and binding groups with the same religion and beliefs in an ideal society. In this research, a quantitative meta-analysis was applied. The population consisted of 34 documents. 27 pieces of research in 2008-2021 were selected (articles related to meta-analysis) using purposeful sampling by observing inclusion and exclusion criteria. The findings indicate that there is a direct significant relationship between emotional religiosity (%37), experiential religiosity (%36), belief religiosity (%30), ritualistic religiosity (%18), and consequential religiosity (%19), and citizens’ feeling of security. Religiosity has a direct significant influence on the feeling of security. Its overall effect is %37. With an increase in religiosity, the feeling of security increases.

 Recent researches have shown that workforce training is significant for achieving organizational productivity. On the other hand, in Islam, man is considered to be the most valuable capital of a society, a worthy being and the best creature; Therefore, this research seeks to find out what the study of human capital is according to the Qur'an.

 The statistical population of this research is the verses of the 60th chapter of the Qur'an, the words "science" and "teaching" were collected in the software of Jamiat al-Tafaseer Noor in the form of thematic interpretation and using the keyword and word method, and the verses obtained with a practical approach by applying the content analysis method. Qualitative induction was coded and analyzed in three stages. The verses of each category were extracted and placed in the form of subcategories. Quantitative content analysis has also been used to obtain abundance.

 The research findings show that human capital education has 14 categories and 28 subcategories from the perspective of the Qur'an; These results are the result of examining the Qur'an and extracting 255 verses from 60 surahs as research sheets.

 Institutional training of human capital from the perspective of the Qur'an expresses the characteristics of human learning and learning, which causes deepening of spirituality, skill training, transformation and increase in productivity in the organization.

Context: 

In today's era, organizational success requires a change in functions, especially a change in management styles and its management, among which the role of spiritual leadership is very prominent, so that people enthusiastically carry out their activities. To achieve organizational goals.The goal is to identify, explain and develop the style of spiritual leadership from the perspective of the Qur'an, so that it can help the training and perfection of human capital in organizations.

This research used inductive qualitative content analysis method, ijtihad method and interpretation method to collect information and analyze data.

Spiritual leadership with a Quranic approach has 5 categories: vision, altruism, hope and faith in work, organizational commitment and productivity, for which 25 verses have been extracted from the Quran.

Spiritual leadership is important from the perspective of the Quran and its presence in the organization motivates people and leads to spirituality in the goals of the organization.

The cichlidae family has more than 1300 species which in turn have great species morphologic differences. In this study, histology of liver, spleen and pancreas of four cichlid species (green terror cichlid, Oscar, giraffe cichlid and Texas cichlid) were compared. For this purpose, four apparently normal fish specimens from each species were selected after killing of which, tissue samples were taken. The sections stained with two methods (Haematoxillin- Eosin and Periodic acid Schiff). The results showed that all liver sections contained pancreas tissues around the liver blood vessels. Liver cells size in two species (green terror cichlid and giraffe cichlid) was significantly bigger than the two other species. The liver cell to pancreatic cell ratios also was significantly higher in two species. The liver size in giraffe cichlid, was even significantly bigger than the green terror cichlid. Exocrine pancreatic cell size in all 4 species showed no significant difference. The spleen in four fish species showed different degrees of amount and intensity in melanomacrophage centers. In PAS stained sections, only the pancreatic tissues showed more PAS positive reaction that may be due to the more glycogen content. The liver showed a weak PAS reaction. The bigger size formation of liver cells in two species can be due to feeding regime or simply a species specific trait. Yet more investigation is still needed to determine the importance of these findings.

Fog computing address numerous cloud computing challenges such as high latency, low capacity and network failure.  The cloud computing infrastructure includes a large number of IoT devices with the ability to process in the cloud environment.  In fog computing, processing and storage provide on IoT devices locally instead of remote servers, therefore, fog computing is the best choice to enable IoT in order to provide efficient, faster and secure services for many users on the edge of the network.  Fog computing have a variety of challenges. One of these important challenges is resource management and task scheduling such that solving this problem has a great impact on system efficiency and service quality. In this paper, we present a task scheduling approach based on the imperialist competition algorithm namely, Imperialist Competitive Algorithm-based Task Scheduling in Fog Computing (ICTF). In the proposed method, we consider the search space as a directional graph. Assume that each task that contains a set of tasks is a graph with a root node and an end leaf node whose middle nodes are the task set. Each path in this graph that starts at the root node and ends at the leaf is a solution represented by a string. This solution is modeled as a country. Therefore, in the proposed method, the concept of country includes the tasks of a job along with the fog nodes that are assigned to these tasks. The initial population consists of a random number of these solutions. ICTF presents a cost function consisting of three important criteria for assessing the initial population of countries and determining the imperialists and colonies countries include energy, execution time and execution cost. The assimilation operation is performed on two different members of countries, namely the imperialists and colonies country, and two new types of members are created called children. The countries participating in this process are among the best countries and are selected using the cost function. In this process, the best offspring produced are passed on to the next generation, and this operation continues until the final population of the countries is obtained. The assimilation operator has different models and in this article we use the two-point assimilation operator. The name of the revolution operator used in this algorithm is the inverse of the task. This operator randomly selects two tasks belonging to a fog node and moves them together. The above operation is repeated until the population converges and reaches the final answer. We show that our proposed approach is more efficient in terms of makespan, resource utilization, energy consumption and remaining energy compared to the similar approach.

This study aimed to investigate the effect of electron beam welding parameters on the microstructural characteristics and mechanical properties of the dissimilar joint between 17-4PH stainless steel and Ti6Al4V alloy. For this purpose, the welding of these two alloys was performed with an copper interlayer with a thickness of 1 mm. Two different welding speeds of 0.7 and 0.9 m/min with four levels of beam offset  (0, 0.2, 0.4 and 0.6 mm) from the center of the interlayer towards the steel were used to accomplish the experiments. The results show that by using the copper interlayer with thickness of 1 mm, the cracks caused by the formation of intermetallic compounds are removed from the weld pool. At the interface between the titanium and the weld pool, at the beam offset  of 0 and 0.2 mm, a solid solution of copper and TiCu2 intermetallic compounds is formed, while at the beam offset  of 0.4 and 0.6 mm, a solid solution of copper and TiCu intermetallic compounds is formed. The weld pool, at the beam offset  of 0 and 0.2 mm, consists of TiCr2+TiFe2 intermetallic compounds while at the beam offset  of 0.4 and 0.6 mm, solid solution of iron (α-Fe), solid solution of copper and TiCu intermetallic compounds are formed. The highest value of hardness is observed at the interface between the weld pool and the titanium alloy, as well as at the interface between the weld pool and the steel, which is due to the presence of intermetallic compounds with high hardness in these regions. By increasing the welding speed and the beam offset, the hardness value decreases, which is due to the reduction of brittle intermetallic compounds in the joint structure. By increasing the beam offset from 0.4 mm to 0.6 mm at the speed of 0.7 m/min, the shear strength increases from 180 MPa to 210 MPa and at the speed of 0.9 m/min, the shear strength raises from 230 MPa to 250 MPa. The welded sample with the welding speed of 0.9 m/min and the beam offset of 0.6 mm has the highest shear strength equal to 250 MPa. The failure in all samples happened at the interface between the weld pool and the titanium alloy, which shows that the weakest region in the joint is this interface.

This study aimed to investigate the effect of electron beam welding parameters on the microstructural characteristics and mechanical properties of the dissimilar joint between 17-4PH precipitation hardening stainless steel and Ti6Al4V alloy. For this purpose, the welding of these two alloys was done without an interlayer and with an interlayer of copper with a thickness of 0.8 mm. Two different welding speeds of 0.7 and 0.9 m/min with four levels of beam offset  (0, 0.2, 0.4 and 0.6 mm) from the center of the interlayer towards the steel were used to perform experiments. The results show that in the direct welding of titanium and steel, the joint structure consists of TiFe and TiFe2+TiCr2 intermetallic compounds with high hardness (about 900 Vickers). In the welding of titanium and steel by using the copper interlayer, the structure in the weld pool and the interface between the weld pool and steel includes a solid solution of copper and TiFe2 intermetallic compounds, and at the interface between the weld pool and titanium includes Ti+Ti2Cu and TiFe. The hardness of the welding zone in the samples welded with copper interlayer is about 400 Vickers. The highest value of hardness is observed at the interface between the weld pool and titanium alloy, as well as at the interface between the weld pool and steel, which is due to the presence of intermetallic compounds with high hardness. By increasing the welding speed and beam offset, the hardness decreases, which is due to the reduction of brittle intermetallic compounds in the joint structure. The welded sample with a welding speed of 0.9 m/min and beam offset of 0.6 mm has the highest shear strength equal to 160 MPa.

From the Islamic point of view, the most valuable asset of a society and organization is manpower; In such a way that the Qur'an introduces man with attributes such as divine successors, chosen creatures and conquerors of all beings. Therefore, the present study seeks to explain the pattern of perfected human capital from the perspective of the Holy Quran.

The present study is applied in terms of purpose via using a content analysis technique. First, by exploratory study, the dimensions of perfect human capital from the perspective of the Qur'an were identified and the categories of each dimension were identified. Then, by referring to the text of the Quran, verses related to each of the dimensions and categories were identified and analyzed, and also the frequency of verses related to each index was reported.

The results showed that human capital from the perspective of the Qur'an has two dimensions of individual and organizational, 14 categories and 36 indicators; These results were the result of examining all verses of the Qur'an and extracting 88688 related verses from 89 suras.

Perfect human capital from the perspective of the Qur'an reflects the innate characteristics of human beings and is strengthened by communication, efforts and education and causes deepening of spirituality, companionship with others, transformation and increasing productivity in the organization.

The sustainability of agricultural systems plays a key role in adapting to climate change. There is ample evidence that biodiversity can increase the stability of ecosystem processes by changing environmental conditions. Therefore, the effectiveness of breeding programs requires a correct understanding of the reaction of breeding cultivars to environments with different climatic and soil conditions. Therefore, this study was conducted to assess the response of some new maize hybrids to divergent environmental conditions and determine their grain yield stability.

This study was conducted with 16 maize hybrids using a randomized complete block design with three replications in six locations, during the 2017 cropping season. Considering significant differences for hybrid × environment (GxE) interaction, stability analyses were performed using AMMI and GGE-biplot methods to determine stable and high-yielding hybrids.

The results of the AMMI model showed that only the first two principal components of AMMI (AMMI1and AMMI2) were significant and described 68.53% of the variance of G×E interaction. Based on the results of statistics of the AMMI model (ASV and SPCA1), hybrids No. 16 (SC704) and 1 (KLM77002/3-1-1-1-1-1-1-3 × K18) were recognized as the most stable hybrids. Stability analysis by GGE biplot procedure explained 71.5% of grain yield variation due to two components of GGE. In addition, hybrids No. 16 and 1 were identified as superior and stable hybrids by the GGE biplot graphical method.

Generally, results of grain yield and stability analyses showed that hybrids No. 16 and 1 with 12.76 and 11.72 t/ha yields, respectively, were better than other hybrids across environments for yield and stability with wide adaptation and thus can be cultivated in Iran. Also, biplot analysis of correlation among environments revealed that Kermanshah, Esfahan, and Shiraz, as well as and Moghan and Miyandoab were closer and similar in ranking, grouping, and assessing stability. Also, Kerman and Karaj regions were less similar to other regions in terms of hybrids discrimination. Considering the high discriminate power of hybrids in Shiraz, Miyandoab, Kerman, and Karaj environments, and in order to decrease the costs, it is recommended to conduct future trials in the aforementioned environments.

Interest in cloud computing has grown considerably over recent years, primarily due to scalable virtualized resources. So, cloud computing has contributed to the advancement of real-time applications such as signal processing, environment surveillance and weather forecast where time and energy considerations to perform the tasks are critical. In real-time applications, missing the deadlines for the tasks will cause catastrophic consequences; thus, real-time task scheduling in cloud computing environment is an important and essential issue. Furthermore, energy-saving in cloud data center, regarding the benefits such as reduction of system operating costs and environmental protection is an important concern that is considered during recent years and is reducible with appropriate task scheduling. In this paper, we present an energy-aware task scheduling approach, namely EaRTs for real-time applications. We employ the virtualization and consolidation technique subject to minimizing the energy consumptions, improve resource utilization and meeting the deadlines of tasks. In the consolidation technique, scale up and scale down of virtualized resources could improve the performance of task execution. The proposed approach comprises four algorithms, namely Energy-aware Task Scheduling in Cloud Computing(ETC), Vertical VM Scale Up(V2S), Horizontal VM Scale up(HVS) and Physical Machine Scale Down(PSD). We present the formal model of the proposed approach using Timed Automata to prove precisely the schedulability feature and correctness of EaRTs. We show that our proposed approach is more efficient in terms of deadline hit ratio, resource utilization and energy consumption compared to other energy-aware real-time tasks scheduling algorithms.

In this research, the influence of H321 stabilizing heat treatment on microstructure, hardness, and intergranular corrosion resistance of 1cm thick sheet of AA5083 has been investigated. After 10%, 20%, 30%, and 40% cold rolling of samples, they were all annealed for recrystallization. The processes of rolling and annealing have been repeated until 1.5mm thickness samples were obtained. Then, 30% cold work was applied to them to achieve sheets having 1mm thickness. For stabilizing treatment, samples were put in the heat treatment furnace for 1 and 4 hours in a temperature range of 150°C to 300°C. Then, sensitization treatment was applied to the samples at 150°C for 48h to consider the effect of stabilizing. The results show that the hardness of samples decreases by increasing stabilizing temperature. The optimum stabilizing temperature for samples with 10% to 30% rolling is 220°C to attain the highest corrosion resistance, but this treatment does not improve the sample's corrosion resistance with 40% rolling. In conclusion, the sample with 20% rolling, which stabilized at 220°C, exhibits mass loss of 6 to 9 mg/cm2 and hardness of 100HV in 4h and 110HV in 1h of stabilizing time has the optimum combination of hardness and intergranular corrosion resistance.

Intensive aquaculture and commercialization production are believed to be needed for improving fish health status and probiotics are candidates to achieve this goal.

In this study, we utilized Lactobacillus plantarum and Lactobacillus pentosus as autochthonous food supplementation for biochemical investigation in rainbow trout.

In the current study, 240 juvenile rainbow trout with an average weight of 15 ± 2 g were randomly divided into four groups with three replications. Group 1, 2, and 3 were fed with 108 CFU/g of L. plantarum, L. pentosus, and the combination of these two probiotics, respectively. The control group was fed with the normal diet, for 60 days (2 % of body weight, 3times per day). Samples were taken at days 0 and 60 and biochemical parameters and hepatic enzymes activity were then investigated.

Most biochemical factors had positive changes in the fish fed with probiotics, particularly in L. plantarum group (p < 0.05). Furthermore, the results exhibited a significant decrease in ALP level in the probiotic groups, particularly in L. pentosus group (p < 0.05). Meanwhile, AST enzyme activity in plantarum+pentosus group was higher than that in the other groups (p < 0.05).

The present results indicated the effectiveness of food supplementation with probiotics in fish diet with the preference of probiotic to improve the biochemical factors and hepatic enzymes activity of rainbow trout, Oncorhynchus mykiss.

Caspian brown trout (Salmo trutta caspius) is one of the nine subspecies of brown trout in the world and is one of the economically and endangered species of Iran. This study aimed to investigate the effect of sodium diformate as an acidifier on biochemical and antioxidant indices in Caspian salmon. For this purpose, the Caspian brown trout fries (salmo trutta caspius) that weight 13±0.05 gr were recruiting for 60 days by employing four diets consisting of levels of zero (control), 0.5, 1 and 1.5 percent with 3 repeats and blood sampling was done at the beginning of the experiment, day 30 and after the end of the test. Biochemical methods were used to determine the activity of catalase, superoxide dismutase (SOD) and malondialdehyde (MDA) enzymes, as well as triglyceride, cholesterol, LDH lactate dihydrogenase and glucose levels. The results showed that the amount of glucose in the first day of all treatments significantly differed from the control group. The amount of serum cholesterol on 30 days of the 0.5% treatment and 60 days of the 1% treatment was significantly decreased in contrast with the control. The triglyceride concentration in all of the groups except the 1% treatment was higher than the beginning of the experiment. Besides, there were significant differences between 0 and 30 days and on day 60 of 0.5 and 1.5% treatments. LDH enzyme level was significantly decreased on day 60 of the 1% treatment when compared to control group. Serum catalase level was not significantly different from the control group on day 60. SOD level after 60 days was not significant compared to the control group. The amount of malondialdehyde (MDA) activity on days 30 and 60 of the 1 and on day 60 of the 1.5% treatment was significantly different from control. The results of this study showed that the acidifier treatments (1% and 1.5%) had a significant effect on the biochemical factor and antioxidant defense of brown trout caspius for the first 30 days but in the second 30 days the results were the opposite.

Model checking is an automatic technique for software verification through which all reachable states are generated from an initial state to finding errors and desirable patterns. In the model checking approach, the behavior and structure of system should be modeled. Graph transformation system is a graphical formal modeling language to specify and model the system. However, modeling of large systems with the graph transformation system suffers from the state space explosion problem which usually requires huge amounts of computational resources. In this paper, we propose a hybrid meta-heuristic approach to deal with this searching problem in the graph transformation system because meta-heuristic algorithms are efficient solutions to traverse the graph of large systems. Our approach, using Artificial Bee Colony and Simulated Annealing, replaces a full state space generation, only by producing part of it checking the safety, and finding errors (e.g., deadlock). The experimental results show that our proposed approach is more efficient and accurate compared to other approaches.

Lactococcus garvieae, the causative agent of lactococcosis, is one of the most important fish pathogens all around the world. The aim of this study was to investigate the inhibitory effects of Satureja bachtiarica and Satureja khuzestanica essential oils against the expression of capsule gene (epsD) of L. garvieae. Bacterial isolates containing epsD gene were exposed to the minimum inhibitory concentrations of the essential oils (0.12 μl/ml) and the expression of epsD gene was investigated by real-time PCR. The results showed that the expression of epsD gene was suppressed in the studied bacterial isolates under MIC concentration of the essential oils. The results also revealed that the gene expression was decreased by increasing the essential oil concentration. However, S. khuzestanica was more effective on the expression of epsD gene than S. khuzestanica. Therefore, the use of S. bachtiarica and S. khuzestanica essential oils can be recommended to prevent lactococcosis in aquaculture via suppression of capsule gene.

Understanding softening mechanisms of wrought aluminum alloy during hot deformation processes is important in order to control microstructure and to predict flow stress accurately in simulation. In this paper, hot compression tests have been done to study the hot deformation behavior of an A5456 aluminum alloy. The effect of temperature, strain and strain rate on flow behavior of the alloy has been studied as well. For this meaning, several cylindrical samples with respectively 10 and 15 mm in diameter and length have been subjected to the test at 350, 400, 450, 500 and 550 °C, strain rates of 0.001, 0.01, 0.1, 1 s-1 and strain of 0.7. The samples where then immediately quenched in water in order to study the microstructure. Analysis of the strain – strain curves at different deformation conditions show that the flow stress decreases with increasing the test temperature and decreasing the strain rate. Because of high stacking fault energy of aluminum alloy, the dominant softening mechanism in this alloy is dynamic recovery. From experimental results, the equations governing the hot deformation behavior of the material have been determined at peak stress and activation energy of 182 KJ/mol for hot deformation process has been obtained.

Today, there are more than 300 types of cars in Iran auto market, which has a significant growth in recent decade. High variety have challenges for decision makers in selecting cars. No mathematical model has been developed yet for segmenting and ranking Iran auto market, which carry out both defining automatic cluster numbers as well as automatic weighting criteria by the model.
This research develops a Hybrid DEMATEL-Two-Step Clustering-TOPSIS approach. The model first finds the beat appropriated criterion for segmentation. Then uses a two-step clustering approach for segmenting Iran auto market based on price criterion. Second, the criteria will be weighted automatically using Shannon entropy weighting method and then, TOPSIS method rank competitors in each defined price segment (lower 900 Million Rials). Also, the Spearman's rank correlation test is used to compare the model results with Iranian customer behavior (with selling volume). The price segmentation results reveal that the Iran auto market can be segmented in six different levels. Furthermore, the ranking results disclose that price is not the only effective factor in finding car utility for the buyer. A weighted combination of performance, features and price will determine optimized selection for buyers.

Viral hemorrhagic septicemia (VHS) is known as the most serious disease of rainbow trout in aquaculture industry. In this study, VHS virus glycoprotein genes were identified in farmed rainbow trout by RT-PCR test. Then nucleotide sequencing and phylogenetic analysis were performed on the viral isolates.
Suspected samples of VHS disease that collected from rainbow trout farms of Chaharmahal and Bakhtiari province were tested by RT-PCR method. Finally, the eight samples were identified as positive VHS strains and nucleotide sequencing was accomplished. Based on phylogenetic analysis, results of nucleotide sequences of glycoprotein gene were compared with other countries.
The results of present study showed that genetic variation in the glycoprotein gene was 0-7.4 percent. There was the highest similarity of glycoprotein gene of Iranian strains up to 100% with Germany strain (EU708818) and the lowest similarity was showed in Japan (AB672616) and Turkey (JF415091) strains with 60/92 percent in each.
Discussion and According to the genetic similarity of the VHS virus isolated from Iran with European strains, especially Germany and France, there is possibility of the relationship between the outbreak of VHS and eyed eggs imported from the mentioned countries.

AA2024 alloy has high strength but low formability. Therefore there is a difficulty during forming processes of the alloy such as rolling, because high capacity of rolling machine is required. So, achievements in good mechanical properties in this alloy besides the improvement in ductility during cold rolling are the main challenges for industries. The objective of this paper is to improve mechanical properties of 2024 aluminum alloy by using a combination of cold rolling and precipitation hardening. To do this, the hot rolled strip of the alloy first solutionized at495 ̊C for an hour and immediately quenched in cold water. The samples were then subjected to 15, 30 and 50 percent reduction by rolling at room temperatures. The cold worked samples were then natural aged for a week. The tensile test and Brinell hardness test were conducted and microstructural study was carried out by metallography. The results indicate that, the 30% cold rolled sample has the maximum strength and hardness in comparison to the T4 or T3 samples.
