Abstract
The study attempted to investigate the association between emotional intelligence and self-efficacy among English teachers. It also attempted to examine the role of experience in predicting this relationship. The present study was pioneering in investigating the role of experience in moderating the association between English teachers’ EI and their self-efficacy beliefs in private English school context. The participants in the present study included 120 English teachers from seven private language schools in Urmia, Iran. Two questionnaires of Teachers’ Emotional Intelligence Scale and Teachers’ Sense of Efficacy Scale were utilized in order to collect data. Bivariate correlations, linear and multiple regressions were run to analyze the data. The findings indicated that there is a positive relationship between emotional intelligence, its subscales, and self-efficacy among English teachers. It was found that emotional intelligence can predict some of the variation in the teachers’ self-efficacy beliefs. It was also found that experience does not moderate this relationship. The study concluded that pre-service and in-service teachers can benefit from training programs that can assist them in blossoming their emotional latencies. The implications of the findings of the present study for teacher educators are that they can benefit from enhancing pre-service and in-service teachers’ EI, which will concomitantly ameliorate their self-efficacy. Future research studies are recommended to concentrate on flourishing teachers’ EI by developing pertinent activities and training courses.

Abstract
In spite of the potential merit of technology-enhanced education in offering an innovative educational game in the arena of English teaching and learning, they have not garnered much momentum in terms of practical research, particularly in ELT speaking domain and their potential role in the Covid-19 pandemic and post-pandemic eras. This constitutes a substantial gap in the extant corpus of literature, which will be addressed in the current study by exploring the short- and long-term impacts of immersive virtual reality and space team ESL games on the speaking abilities of Iranian EFL learners. To this light, 54 basic EFL students from private language institutions in Urmia were selected through convenience sampling and an intact group design. Three classes were randomly exposed to two treatments, encompassing virtual reality, space team, and a control group receiving traditional instruction. The participants were pre-tested with the IELTS speaking test before receiving the treatment, and the same instrument was utilized for post-tests and delayed post-tests. In contrast to the traditional group, the results demonstrated that both immersive virtual reality and space team games enhanced students' short- and long-term oral performance. The findings of this study could be well-regarded as an important proposal for considering game-based instruction as an integral component of ELT classrooms and a technique for promoting language proficiency in non-native contexts.In spite of the potential merit of technology-enhanced education in offering an innovative educational game in the arena of English teaching and learning, they have not garnered much momentum in terms of practical research, particularly in ELT speaking domain and their potential role in the Covid-19 pandemic and post-pandemic eras.

Abstract
One of the main goals of developing countries is to achieve a sustainable economic growth. The exports promotion can directly help economic growth. Therefore, recognizing the factors influencing economic growth is of utmost important. Regarding the significance of factors affecting non-oil exports in trade policy making, this study aims to investigate the impact of exports insurance subsidy and other relevant variables on non-oil exports in Iran. To do this, the short- and long-term relationships between non-oil exports and exports insurance subsidy are estimated by Auto-Regressive Distributed Lags (ARDL) over the period 1995-2011. The results show that exports insurance subsidy is of positive effect on non-oil exports in both short- and long-term.

Abstract
Composites that withstand high temperatures are one of the parameters that always is the focus of attention. Especially when this type of material in sensitive parts flying craft is used. Generally, sensitive parts of flying craft should be also, radar transparency, have good mechanical strength at high temperatures. PTFE matrix composite is one of the options suitable for this purpose. PTFE is one of the polymers that have high heat resistance and low dielectric constant. This article processing preparation of glass fiber reinforced PTFE polymer matrix composites with conventional sintering methods. Then composite sheets made from E-glass woven fabric with PTFE have been produced with conventional sintering methods. To achieve optimal sintering processing of PTFE matrix composite, various cycles of time and temperature were selected and the optimal sintering cycle for such composite materials is obtained by the design of the experimental method. Then the mechanical properties of composites with different sintering processes were measured. To determine the mechanical properties, a tensile test was performed, and to determine the electrical and electromagnetic properties, a dielectric constant test in X-band was performed. The loss tangent, as well as composite products obtained. The maximum tensile strength and tensile modulus were achieved in this research respectively equal to 130 Mpa and 3.65 GPa. Constant dielectric and Loss tangent of the samples produced in the x-band are 2.37 and 0.096, respectively. Finally, to validate results in this research, the results of the performed tests were compared with the results of other references in this context.

Abstract
Ultra-High molecular weight polyethylene (UHMWPE) fibers are among the strongest and lightest fibers available and are widely used in high-performance ballistic applications. Despite the great advancement of computational analysis in recent years, precise calculations have not been performed to identify the failure of these fibers due to the complexity of the material behavior to impact. In this research, using the most advanced finite element modeling method of composites (Abaqus-Explicit) has been used to study the composite behavior of these fibers subjected to high-velocity projectile impact. Fiber and matrix are designed using solid elements and 3D Hashin failure criterion was used to determine the behavior of the material. Since this criterion is not available in Abaqus, the VUMAT subroutine has been used to implement this criterion. Velocity diagrams and damage evaluation have been reported. To evaluate and validate this method, six samples of Ultra High Molecular Weight Polyethylene (UHMWPE) Composite panels, consisting of 20 and 45 layers, respectively, were experimentally studied by high-velocity projectiles at different velocities. The simulation results are in good agreement with the experimental results.

Abstract
The milling process is widely used in the manufacturing industry to shape complex geometric parts. Considering the flexibility of the cutting process and the various variables involved, process optimization has become a key issue in achieving higher productivity and quality. To optimize the process planning, it is important to choose a suitable machining strategy. Implementation and selection of tool path strategies and orientations are very important in the machining process, especially in the aerospace and molding industries. The right choice can lead to significant savings in machining time, improvement of work-piece surface quality, and improvement in tool life, thus leading to overall cost reduction and higher productivity. Therefore, this article aims to identify the best strategy in terms of surface roughness and milling time. In this article, Shallow's strategy has been investigated, and the milling of its finishing stage has been studied and compared with three strategies of the milling process, including raster, 3D offset, and raster flat. In this article, the comparison of the strategies in the Powermill software and with the flat-head finger mill, which can grind the floor and the wall simultaneously, has been done. Tool-cutting parameters were considered constant for all tested strategies. Machining quality was evaluated by comparing surface roughness, surface Topography, and dimension control parameters. The results indicate that the Shallow machining strategy has the lowest surface roughness and the best surface quality, and the raster strategy has the highest surface roughness and the worst surface quality in this test.

Abstract
The research is about developing a solution to prevent deprivation of grandchildren from the legacy of the grandfather after the death of the father. Since the inheritance will be a source of livelihood for the grandchildren, they are the most closest to the grandfather. This is the fact that scholars and jurists give their opinions on the matter of the presence of uncles for the grandchildren and their inheritance. The aim of this research is to try to find a solution to this problem based on the opinions of two jurists because the issue of inheritance is important and one of the important legal matters in society. The study seeks answer as: Why are grandchildren deprived of inheritance after the death of their father, especially with the presence of uncles? What causes conflict between families and what the grandchildren go through from poverty? In this matter, Shiite and Sunni jurists believe that the grandchildren do not inherit their grandfather as long as uncles themselves are present, that is, the grandsons cannot get anything in the presence of uncles or aunts. As the grandchildren "go down," the nearest to them blocks the farthest ones. However, there is no explicit indication of such deprivation in Qur’anic verses and Hadiths. Based on opinions of some jurists, the study reached to the conclusion that when grandfather writes his Will, grandchildren get about one-third of the inheritance but they don’t get the same currently. The research takes the descriptive and analytical method as an approach since it accommodates the areas in highlighting all opinions and interpretations.
