Abstract
The need to address reading skills in language teaching is important because it is related to the other three skills (listening, speaking and writing) and ultimately affects the main goal of language teaching, which is the ability to create effective communication. Now, given the presence of all mobile phones and laptops, questions arise, to what extent are electronic opportunities included in the educational content of the Russian language in Iran? Аanswering this question, as well as analyzing questionnaires with eleven main questions regarding the inclusion of new technologies, cultural topics, playing with proverbs and other issues raised in the teaching content of the reading lesson, as well as questions about whether such materials are included in the reading textbook or not, we came to the conclusion that there is an acute lack of new technologies and other things in the educational content of reading. Therefore, the authors of this study propose new ideas in the educational content of reading to solve existing problems and improve the educational process of teaching reading in Russian at the undergraduate level.

Abstract
The relocation of nutrients and water fluxes to the forest floor varies spatially due to partition of rainfall into throughfall and stemflow by tree canopies. In this study, nutrient concentrations of rainfall and stemflow were measured for seven rainfall events in Chaboksar area in the Hyrcanian ecozone of Iran composed of Juglans regia Linn and Cup. Sempervirens L. Var. Fastigiata where such information was absent. In the course of the study, a total of 24 samples were collected, and stemflow samples of these species were analysed in relation to rainfall. The results of this study suggest that the nutrient concentrations in stemflow are mainly influenced by vegetation species. The concentrations of CaCO3, nitrate, calcium, magnesium, sodium, zinc, and chloride, were all higher in the stemflow of cypress tree than that of the walnut tree. The concentration of iron in both stemflow samples was zero. The pH level in the stemflow of Juglans regia Linn and Cup. Sempervirens L. Var. Fastigiata was slightly lower than rainfall pH level. However, in terms of heavy metals, the concentration of lead in cypress stemflow was found to be higher than that in walnut stemflow. Furthermore, a very small amount of copper was detected in the stemflow of cypress tree. Electrical conductivity of cypress stemflow was also higher than that of walnut stemflow.

Abstract
The item of livability is one of the closest concepts to the quality of life that through it an ideal environmental society can be estimated. Therefore, any increasing or decreasing in the amount of livability is a means to evaluate staying inhabitants in the neighborhoods, regions, and cities. Also, it is a measurement for estimating the quality of life. While the city is developing, at the same time, all its traditional, new and periphery neighborhoods are facing to variety of physical, cultural, etc changes. So, due to existence of some challenging issues and necessity of livability to inhabitants, this needs to be assessed. In this study, three different neighborhoods including Haji, Etemadieh, and Mazdaghineh are investigated. It is interesting that all of them situated in 2 region municipality in Hamedan. There would be four components including physical-spatial, social-cultural, economic, and environmental items. The analytical-comparative methodology is used and in order to data analyzing and final evaluations, SPSS 19 and Expert Choice 10 technique is implemented and finally AHP method is used. To gather data observing, completion questionaires by residetial neighborhood and interviews with experts are used. Final results exhibited that the amount of livability in the neighborhood of Etemadieh is the most, nearly 0.431 points, and Haji and Mazdaghineh respectively are the second and the third livability neighborhoods with 0.322 and 0.246 points. The physical and economic components in Haji neighborhood are more favorable than other neighborhoods, but the social component in Mazdaqineh neighborhood is superior to the other two neighborhoods. The Etemadiyeh neighborhood is also a priority in the environmental component over other neighborhoods.

Abstract
Forming urban heat islands is a serious challenge of the present age and a concern of academic communities. Attention to this issue has increased tremendously in scientific articles and researches, particularly in the last decade. With regard to the importance of the issue, the aim of this study is to form a systematic review and thematic analysis of articles and other researches in this field. Moreover, the content of the key articles was analyzed and the most important factors affecting the formation of urban heat islands were represented in a diagram and each of them was analyzed separately. As examined, urban heat islands are affected by climatic and urban construction factors. The climatic factors include sunlight, wind speed and direction, cloud cover, soil moisture, air humidity, precipitation, latitude, seasonal topographic variations, and the proximity to the river and the sea. Although these factors are almost uncontrollable in the existing cities, they have enormous importance for deciding new towns location and making the decision for city development direction. The second group of factors mainly related to the design of cities is controllable. Among these factors, the most important one is the amount and quality of vegetation in the city. Other factors such as land use, urban density, type of materials used on the facade of the buildings and streets, form and geometry of the city, and also transportation mode could influence the intensity and extent of urban heat islands.

Abstract
In his classic paper on the philosophy of religion entitled ‘The Presumption of Atheism’, Antony Flew, relying on a traditional legal rule, extracts a methodological rule according to which the burden of proof in the problem of God’s existence is non-restrictedly on the Theist. Here we argue that from another legal rule in Islamic jurisprudence, we can extract another methodological rule that, in contrast to Flew’s rule, is context-dependent; so, applying this new rule, we can imagine that in some situations, the burden of proof would be on atheist. Since there are some historical evidence for the relationship or even identification of that traditional rule and this Islamic rule, it could be concluded that Flew’s rules, too, should be context-dependence. Hence, his non-restricted claim about the burden of proof in the problem of God’s existence will be rejected.

Abstract
In this paper, we will try to reconstruct Hegel’s logic and metaphysics through modern logic. Graham Priest has claimed that we can read Hegel’s logic with the paraconsistent approach to logic, specially Dialetheism; he calls Hegel a Dialetheist. At first, we report Priest’s account of Hegel’s dialectic and his notion of dialectical contradiction; also, we try to analyze Priest’s argument for calling Hegel a Dialetheist. To achieve the proper comparison between Hegel’s logic and Dialetic one, we explain, non-technically, the simple semantics of a Dialetic logic. Furthermore, finally, we establish a criticism of Priest’s account to reopen the question about Hegel’s being Dialetheist.

Abstract
Introduction: Spatial planning is a set of measures to organize the distribution of human and activities carried out in the geographical space. Each area should enjoy a range of economic and social activities based on its capabilities, needs, and situation. Spatial planning is the basis of organizing regional development and it is the main instrument for regional and national planning and policy making; it provides the basis for the preparation of socio-economic development plans for each area or country. Since for the fulfillment of development objectives all social resources, including human, economic, spatial, and environmental resources should be used and making use of all these elements needs planning, spatial planning is the basis of comprehensive development plans and projects and connects spatial, social, and economic planning, or as a whole in the form of comprehensive planning, in regional and national scale. Border areas have special characteristics due to their contacts with the external environments. The cross-border exchanges and spatial connections between the adjacent countries as well as the various vulnerabilities and threats posed by this issue necessitate special care to the process of development planning in these areas. The aim of the present research was to investigate the employed strategies for spatial plannig in brder areas in Five-Year economic, social, and cultural development plans of Islamic Republic of Iran (1st to 5th Plan).
Conclusion: In general, and especially in the 3rd and 4th plans, the economic strategy is more important. Also, spatial differences have not been considered in 5-year development plans; strategies ignored the differences in the various border areas of the country and looked at all areas in the same way. In addition, a special type of strategy is focused in each plan.

Abstract
Introduction: As one of the oldest and the most dynamic branches of political geography, Electoral geography has experienced ups and downs more than other branches of political geography. The objective ontology of the phenomenon of vote and its spatial distribution have linked this branch to spatial approach so that a large proportion of works in the area of Electoral geography have been written based on this approach. With the fall of positivism, the researches of Electoral geography also decreased. On the other hand, domination of descriptive, case, and applied studies without a robust theoretical and philosophical basis on theoretical and basic writings, is the main deficiency of Electoral geography in International and Iranian level. The aim of the present theoretical-fundamental study was to explain the dominant theoretical approaches in Electoral geography.
Conclusion: The Electoral geography can be explored in five theoretical approaches. The first approach is the traditional approach that deals with the spatial patterns of voting in the form of a regional school and human-environment relations. The second one is a spatial-behavioral approach that examines the voting behavior according to the measurement and analysis of key spatial variables based on the spatial school. The third approach is a radical approach that base on radical geography school deals with the theoretical articulation and revealing mechanisms that form Electoral processes. The fourth approach is a location-based approach that focuses on the impact of geographic-historical context on electoral behavior on the basis of the humanistic geography school and structuration theory. And, the fifth approach is a critical approach that criticizes the current approaches to the study of electoral geography and the presesentation of alternative readerships of electoral geography based on schools such as feminism, post-structuralism, and post-modernism.

Abstract
In the philosophy of religion, Divine Agency has been related to how God does his action in the human world and the physical world. Polkinghorne has presented a particular method to answer this question. His theological approach has been a combination of Classical Theology and Process Theology. On the one hand, he has said that the God defined in Classical Theology is too unavailable, and on the other hand, he has criticized the Process approach to God. Polkinghorne has established that Epistemology is equal to Ontology, and based on this fact, he has explained his Critical Realism. In his view, the guaranty of reality is not to understand it but is its objectivity. Uncertain situations in Modern Physics presented in Einsteinian Relativity, Quantum Theory, and Chaos Theory is the main areas Polkinghorne has constructed his specific theory about Divine Agency on them.

Abstract
Thoughts Kierkegaard, one of the leading pioneers of existentialist philosophy, has greatly influenced Sartre's existentialist ideas and his literary and theatrical works and prominent filmmakers in the history of world cinema and other artists in other fields. In this article, organized in three parts, we aim to examine the reflection of Thoughts Kierkegaard's on categories such as "truth, forgetfulness, domination of popular beliefs, existential and non-existent human beings, individualization and liberation from Intermediate, and freedom and Selection." Sepehr Hasti and ... " are among the factors that Sartre's literary works are completely influenced by and in artistic forms and forms and the form of images and dramatic phenomena in dramatic and literary works, Sartre's screenplays are skillfully, creatively, and attractively reflected. Has found. In the form of fascinating visual events, stories, and adventures, these phenomena have woven and implemented the abstract ideas of existentialism in such a way that its created characters, as if living in their natural life and in a completely real way, disappear. Sartre's plays The Flies, a historical work adapted from the Greek playwright Euripides, The Noble Prostitute, the subject of contemporary American society, and The Infected Gangs, whose adventures and events take place. Concerned with World War II and the French resistance movement, it has received the most influence from Kierkegaard's philosophical thought. In this article, we have shown the extent of Sartre's influence on Kierkegaard by examining these plays.

Abstract
Administrative political decentralization, the move towards political development and the management of geographic space are one of the main concerns of governmental systems in developing countries in general and in Iran in particular to achieve democracy. Such a decentralization follows a special approach to the geographic (Natural human) characteristics of each country as well as the type of administrative political system that governs it. However, the most important regional geopolitical decentralization in each independent political unit is the local government. Local governments play an effective role in optimizing the management of human habitats with the knowledge of geographical areas and human rights. Therefore, the present research seeks to answer the following questions: What are the effective elements in the formation of an effective local government in Iran? The method of this research was descriptive- analytic, which has been done by studying high-handed documents and rules in Iran, as well as studying the human-natural characteristics of Iran to identify the indices and elements effective in the formation of an efficient local government. Findings of the research indicate that the decentralization and delegated powers to non-central places and the distribution of power at the geographical level are scattered in some of the laws and documents of the Islamic Republic of Iran.

Abstract
The spatial arrangement of the elements of the spatial organization will lead to sustainable development, if it considers three main components of the environment, economic growth, and social development, with emphasis on human-centeredness. In order to identify imbalances and balances in spatial distribution, it is very important to use appropriate methods that have the ability to combine various indicators into the spatial organization. The purpose of this study was to determine the strategic factors affecting the political management of the Arak township spaces through library and field studies in the first stage and, secondly, the ranking of these factors based on their importance and their impact through the Analytical hierarchy process for the proper management of geographical spaces of the Arak Township.
This study is a descriptive approach based on nature and is applied developmental based on the goal. The research method is descriptive-analytic and library, internet, and interviewing materials are used for gathering information. Analytic hierarchy process (AHP) technique have been used for weighing the factors.
Conclusion: After determining the importance of each of the factors, The existence of suitable business development Potentials with cargo and passenger terminals and the international exhibition site in Arak, Unstable exploitation and overcapacity of natural and environmental resources, existence of target markets, especially in neighboring countries, market failure and unpredictability of some agricultural production support policies were recognized as the most important internal and external factors of the township.

Abstract
The present paper seeks to examine factors affecting the sense of security of religious tourists on the border of Mehran as a model of border towns. The research method is descriptive-analytic. Data was collected through library studies and a questionnaire. Data were analyzed using SPSS software and hypotheses. Findings show that there is no meaningful relationship between personal characteristics of respondents between their age and their sense of security. There is a significant relationship between the sense of security and gender, the sense of security and education of the respondents, and the sense of security and the status of the marital status of the respondents. In terms of tourists' safety, the security of a person with T=37.4 is most secure. Road safety with a T-value of 97.2 is in the lowest category security. According the Sperman test, in the study of the relationship between total safety indices and sub-indicators of tourism development, the highest correlation coefficient between total security and re-visit with a correlation value of 5.30 is obtained. In examining boundary measures for border city security, the predicted variables predict 0.79% of the safety sensitivity variance, and all variables significantly predict safety. The efforts of security officials to secure security on both sides of the border with (Beta=0.526; has the highest impact on the variable of security.

Abstract
The spatial boundaries are not just important in the macro and international levels, but also are significant at the local, regional and national levels. They are significant in areas such as Mamasani County in which the social structure has the tribal nature. The spatial-identity boundaries are appeared due to the dominant tribal atmosphere. On this basis, the areas of culture, society and politics are overshadowed. Tribalism and socio-political boundaries in these areas consolidate each other through factors such as identity, geographic space; the creation of symbols and values; the emphasis on the notions of one's self and others; friendship, hostility and competition and the elections in local level (city council and village or parliament). This kind of solidarity plays an important role in stabilizing local- tribal and traditional political behavior on the one hand and perceptual and spatial boundaries on the other. This situation has consequences such as tribal divergence, cultural introspection and border demarcation. The current research is based on the question of what is the relationship between tribalism and socio-political boundaries in Mamasani. In explaining the research hypothesis, it seems that tribalism and socio-political boundaries mutually reinforce each other. The research is conducted using the descriptive-analytical method and the required data have been collected through library, documentary and field (observation) methods. The findings show that tribalism and socio-political boundaries had mutual effects on each other so that tribes were socialized and politicized during the reign of the Khans and after the fall of the Khans, tribal boundaries have also been influential in intensifying clannish attitudes.

Abstract
Thomism has had a continuous history from the 13th century, and some think it is unique in this regard. Each time, it experienced different forms and took different approaches, as in the twentieth century, there are also transcendental Thomists and existentialist Thomists. However, it took longer for analytic philosophy and Thomism to have interaction, and it did not happen until the attempts by Peter Geach, Elizabeth Anscombe, and Anthony Kenny. Then, in the 1990s, John Haldane, drawing on these works, coined the term "Analytic Thomism". Here I explore this movement by focusing on some of its aspects. First, we will see the historical phases of Thomism. Then, we review the roots of analytic Thomism as we know it now. After looking at some examples of the works done in this tradition, some challenges for analytic Thomism are presented and discussed. By way of conclusion, a few remarks about “Analytic Islamic philosophy” are discussed.

Abstract
Emergentism bears similarities to the Islamic Transcendent Philosophy about the relationship between the soul and the body. At the same time, despite these similarities, there seem to be fundamental differences in the ontological picture of these two. The main issue of this paper is to identify these differences. The result of this effort can be summarized as saying that the ontological foundations of Emergentism are consistent with scientific findings, while this is not the case with Transcendent Philosophy, and that there are fundamental differences between the ontological picture of Transcendent Philosophy and Emergentism in relation to the soul and the body relation; Differences rooted in the contradiction between the classical or Aristotelian image of the world and the new scientific image of the that.

Abstract
Discovering the differences between the various systems of modal logics was one of the advantages of inventing Kripke semantics. One of the most obvious examples is interpreting the necessity of provability in provability logic. According to Boolos in The Logic of Provability, by discovering this logic, we can say that the understanding of new issues in the field of argument was opened. In this paper, with a formal approach and with a descriptive-analytical and comparative method, the axiomatic propositional systems of the GL, Grz, and H, and their possible world semantics based on Kripke semantics are studied, as well as the sequent calculus of GL (in Peano arithmetic) and GLS (in the standard model) were introduced. Finally, the meta-theorems of soundness, consistency, and completeness of the GL were interpreted and proved.

Abstract
The percentage of urediniospore germination of two isolates of yellow rust {Puccinia
striiformis f. sp. tritici) namely, WYR 69/10 |Race 104E 137(1)] and isolate WYR 79/4
|Race 41E 139 (4)], was studied at various temperatues between 5-20°C on agar and
the adaxial surface of detached leaves on a layer of benzimidazole agar. Four
replicates for five temperature treatments were arranged as a preliminary
investigation to find the most appropriate temperature for the subsequent comparison
of spore germination on the host material under investigation. Mean percentage
values were analysed separately and the levels of urediniospore germination at
different temperatures were compared using analysis of variance and Student-
Newman-Keuls techniques. Spore germination of both isolates was high over the
temperature range 5-10°C, but dropped significantly at 15-20°C . At the cooler
temperatures 5° , 7.5° and 10°C , isolate WYR 69/10 consistently germinated at a
higher level than isolate WYR 79/4 , whereas at 20°C, the latter isolate gave the
highest figures. This observation indicates that both isolates germinated most
effectively at 10°C on agar and detached leaves.

Abstract
One of the problems for use of rubber in various industries is the surface tension at the surface of rubbers, which results in the crack on the surface, fracture of the rubber and reduces its service life. These tensions are caused by contacting the rubber component with the metal surface and the friction between two surfaces. Roughness of the surface, the composition of the rubber compound, the environmental factors, test conditions and etc. affect the friction between rubbers – metal. Surface roughness plays an important role in sliding between two surfaces and mainly controls friction behavior. On the other hand, roughness effect on the coefficient of friction is controllable using a suitable lubricant. In the present study regarding to the application of JP4 as an aviation fuel, the effect of JP4 fuel as a lubricant was investigated in the reduction of the sliding friction coefficient between the NBR and aluminum surfaces with different roughness. Experimental studies showed, friction coefficient has a good correlation with the mean surface roughness (Ra). By applying JP4 lubricant, the coefficient of friction decreased by about 75%. JP4 fuel as lubricant has changed the trend of varying friction coefficient from decreasing to increasing regard to the surface roughness.
