Among the lexical units of a language, all of which can be subjected to semantic expansion according to selection and combination, verbs are quite susceptible to radial and semantic expansion due to their nature. This article tries to use the cognitive approach to investigate the semantic expansion of the simple triad form of the event "Zarb" in the Arabic language. And in a descriptive-analytical way, while enumerating the marginal expansions of this verb, explain how they are produced and also the semantic sharing relationship between the derivatives of the same root. About 80 usages were extracted from the most advanced to the latest Arabic dictionaries for the event "Zarb", which, excluding similar usages, resulted in 32 radial meanings for this event. The result showed that the existence of a semantic relationship between the derivatives of a word can be confirmed in the light of the derivational property of the Arabic language. Therefore, from the most unmarked meaning of "stroke" to its metaphorical expansions, each of them conveys the concept of "pressure and force" in a way. Therefore, the claim that the meaning of "beating" is late in this event is questionable. Also, most of the marginal expansions of the verb "to multiply" are the product of the change in the most frequently used elements accompanying this event, i.e. space scenes. In addition, in the virtual expansion of the event "hit", the necessary-necessary interest and the cause-cause have more frequency in producing the radial meanings of this event.

In this paper, a new propagation model based on UTD for multiple diffraction paths in cellular mobile radio communications in urban environments is proposed. Moreover, the most rigorous novel UTD-based expressions for multiple diffractions by buildings and excess path losses are d - rived and analyzed. For this purpose, building rows are supposed to have rectangular cross-sections with the same heights and spacings. In addition, in this analysis actual electrical roperties of buildings are regarded. Previous studies have been concentrated on the simplified models that approximated building rows as absorbing half-screens or perfectly conducting half screens (knife-edges) or 90 degrees wedges. In this work, buildings are assumed flat-roofed parallel rows of dielectric blocks and their actual relative permittivity and conductivity are applied.

Religious pluralism is a suitable successor for two approaches including religious exclusivism and inclusivism. More compatibility of religious pluralism with the modern world’s requirements is led to more welcoming to it. This approach, however, is unacceptable based on its foundations, principles and especially results. Some significant reasons that it can’t be acceptable are as follows: 1. It causes people to neglect other religions’ facts; 2. It does not pay attention to some vital differences within religious traditions; 3. Welcome to religious pluralism is led to vain the question and asking for religious truth and human beings' salvation; 4. Accepting it is caused by epistemic relativism and meaningless of seeking for religious truth; 5. Attaching it led to vain divine revelation and the philosophy of Prophethood; 6. Believing in religious pluralism is caused to destroy differences between intellectual and imitative religiosity; 7. Debasement religiosity and religious creeds are as welcoming to religious pluralism; 8. Accepting it leads to violation in divine attributes and insult to divine dignity of God; 9. Welcome to religious pluralism is caused by religious immorality, and 10. Destroying the religious identity of believers. Now, considering unacceptable results of religious pluralism, and some problems of religious exclusivism and inclusivism, I suggest the Gradual Approach to religious truth and salvation, in the sense that these divine graces have been distributed gradually and hierarchically and longitudinally in all religions, although the final salvation is depended on human being’s struggling and effort.

The monotheistic tradition, especially in Abrahamic religions, emphasizes the belief in an omnipotent, omniscient, purely benevolent, just and wise God. Such a view is threatened by various forms of evil-beliefs, and if logical and convincing answers cannot be given to it, it is a serious threat to the tradition of monotheism. In this article, it is shown that due to the presence of the infinite God's activity on one side of the equation of the problem of evil, the most logical solution is to use the total of possible answers in a combined and unified way, because the combination of the existing ways brings closer to the answer and is more convincing in this context. Therefore, while paying attention to the differences between the metaphysical, natural and moral evils from each other, combining answers such as the relativity of evil, evil as a necessity of human free will, seeing evil as a punishment for human sins, evil as the cause of human spiritual excellence, and seeing the world of the hereafter and the importance of the eternal perspective are needed as the final manifestation of the evil philosophy.

Age structure, growth and mortality index of 661 specimens of spirlin, Alburnoides eichwaldii, from Shirood River in Mazandaran Province were studied during April 2011 to March 2012. The average total length, weight and age of the specimens were 68.33 ± 16.92 mm, 4.9 ± 3.2 g and 1.32 ± 0.86 years, respectively. The fish were in the age range of 0⁺ to 3⁺, of which the 0⁺ year specimens dominanted the age groups in the river. The largest specimen was 111.4 mm in length and a weight of 15.5 g. Comparing total length and weight of fish showed significant differences various ages (P < 0.05). Based on Pauly formula, population growth pattern was negatively allometric (b = 2.94). Based on von Bertalanffy growth equation using the FiSAT program, L_∞, K and t₀ were 12.08, 0.55, and -0.47, respectively. The growth performance index was up to 3.65.  Mortality indices for the fish were calculated as 2.41, 1.19 and 1.22, respectively for the total (Z), natural (M) and fishing (F). Considering the ecological, biological and ornamental value of spirlin as well as its vulnerabilty to serious environmental degradation, such studies may be useful in the protection of the species.

Investigating and studying the political relations of countries in the international arena, especially the countries of a particular region, is of particular importance. Such studies investigate issues related to the interactions between states and factors affecting political relations between them from different perspectives. Geopolitical studies are among such studies which provide national interests and national security for countries to identify political and geographical factors and variables affecting the political relations of states and accordingly, to investigate the regional and global impacts of these relations. By looking at the political relations between Iran and Syria, as two important non-bordering Middle East countries with special geopolitical and geostrategic importance in the axis of Islamic Resistance, which plays an essential and decisive role in regional interactions and geopolitics which is significantly impacted by these relations, we can observe fluctuations due to the influence of geopolitical, political and economic factors in the interactions between them. The current study tries to examine the impact of major geopolitical factors between the two countries and finally answer the following question: What predictable prospect exists for Iran-Syria relations in the future"? In this regard, using a descriptive-analytical research method, we will test the hypothesis that "the future of Iran-Syria relations depends on the future of Syria and its future positioning." This research investigates other aspects of the future effect of the two countries' relations on the region and, like any other research studies, there were limitations and obstacles.

Research subject: Selectivity and permeability are the major parameters of polymeric membranes in gas separation process. Hence, nowadays in order to improve aforementioned parameters, modification and enhancement issues for such membrane have been highly noticed.
Research approach: In this study, in order to improve the performance of polymeric membranes, the two-component blend membranes containing Pebax^®1657 and PVA were synthesized for CO₂ separation. The effect of different PVA concentrations within the Pebax matrix on structure, morphology and gas separation properties of resultant membranes was investigated. The chemical bonds, crystallinity and cross-sectional morphology studied through, Fourier transform infrared (FTIR), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM), and were utilized.
Main results: The results of the thermal analysis indicated an increase in crystallinity and also glass transition temperature in presence of 5 – 15 wt.% PVA, while the membrane crystallinity decreased by increasing the PVA content up to 20 wt.%. FESEM images demonstrated a uniform cross-section without any cracks and defects for neat Pebax membrane but by adding PVA to Pebax matrix, appeared cracks and cave structures on the cross- section of blend membranes. The CO₂/CH₄ separation performance of membranes was measured using a constant volume set up at 30°C and feed pressure of 2, 6 and 10 bar. The obtained results revealed that the CO₂ permeability in blend membranes improved as the PVA content increased within the membrane. The best obtained CO₂ permeability was 204.64 Barrer which gained by Pebax/PVA (20wt.%) at feed pressure of 10 bar. Moreover, the highest selectivity of CO₂/N₂ for blend membrane with 15 wt.% of PVA was about 100.21 at 10 bar and 30°C.

The production of bioethanol from lignocellulosic biomass could be considered as an appropriate and economic option to remove environmental disasters and improve energy security. In fact, lignocellulosic material is mainly composed of cellulose, hemicellulose and lignin. Lignin works as the adhering prevents the bioconversion of cellulose into sugars and ultimately to ethanol. To address the problem, various chemical, physical, physicochemical and biological methods have been suggested. Enjoying convenient operating conditions, production of non-hazardous wastes, and having no harmful side effects, make the biological methods a potentially proper option. Unfortunately, the biological methods are slower and less efficient in comparison with the other processes. In the present study, an attempt is made to resolve this problem in an enzymatic degradation of lignin of a rice straw sample. Several peroxidase enzymes were produced by a white rot fungus, and their effects on lignin removal from the biomass samples were investigated in shaking flasks. Lignin concentration and enzymes' activity were measured by the acetyl bromide-soluble lignin spectrophotometric method and optical density method using special reagents, respectively. The results revealed that the enzymatic treatment could remove at least 30% of the lignin content of the lignocellulosic biomass. To achieve the maximum activity of the enzymes, The chemical composition of the culturing medium was optimized for the concentration of important metal ions including Cu2+, Mn2+ and Zn2+ through Box Behnken response surface methodology. The enzymes' activity at the obtained optimal conditions increased four times for Manganese peroxidase, and lignin peroxidase.

According to the prevalent beliefs, comitative object, cognate object and object of purpose are not present in the syntactical functions of Persian language. However, there is lack of scientific research on this subject. Not only has it been ignored in grammar books, but also it has not been discussed in the essays and articles. The present study seeks to investigate the above mentioned functions in Persian syntax and to show their Persian equivalents by bringing several instances from Persian texts of prose and poetry. Subsequently, the paper aims to show the differences between these functions in Arabic and Persian. Influenced by Arabic, the article introduces new terminology, which did not formerly exist in Persian language.

As an important country in West Asia, Turkey has an influential position on Iran's foreign policy, and considering the bilateral and trans-regional relations in the relations between the two countries, it can be very important from a geopolitical point of view. Developments in recent years in Turkey have been mainly related to the foreign policy of that country. Relations between Turkey and Iran have undergone many changes throughout history. The two countries are considered as powerful non-Arab countries in the region that have common geographical and cultural features and do not consider each other as an existential threat. In recent years, political differences between the two countries over Syria and sometimes Iraq have led to political disputes between them. This scientific study examines the impact of Turkey's geopolitical actions in Iraq and Syria on reducing Iran's regional influence. The research method is descriptive-analytical, it is descriptive because it describes Turkey's geopolitical actions in Iraq and Syria and is analytical. This is because it expresses the impact of these actions on reducing Iran's regional influence. The method of collecting information is library, based on the use of relevant letters, reports, information and valid data. The results show that although Turkey's geopolitical actions have caused conflicts between the two countries, the maturity of the two countries' diplomacy and some similarities have led to the stability of relations.

Biofilter is one of key components of recirculating aquaculture system (RAS) that affect initial investment, executing cast and success or unsuccess of system. Hence in this research, performance of barley straw, wood chip, sponge (as cheap and available media) and PVC pure pipe (to compare) based biofilters was surveyed in Common carp recirculating aquaculture system. To conduct this research 12 pilot recirculating aquaculture systems designed and 50 common carp individuals (mean weight: 4/8 g) were stocked in each system. After activation period (about 1 month), waste removal efficiency of biofilters and growth performance of Common carp were surveyed. Results indicated that sponge based biofilters had the best performance. Barley straw and wood chip based biofilters showed acceptable waste removal efficiency, while PVC pure pipe biofilters had poor performance. The highest feeding and growth performance of fish were observed in systems involved barley straw based biofilter. In conclusion barley straw, wood chip and sponge because of having low cast, being available, having relatively high specific surface area and showing acceptable waste removal efficiency, can be used in RAS and semi reuse systems.

This experiment was conducted to determine the effects of three binding agents, including corn starch, carboxymethyl cellulose (CMC) and urea formaldehyde (UFA) (in diets containing 42% soybean meal) on growth performance, pellet water stability and chemical composition of Litopenaeus vannamei. Shrimps with an average initial weight of 0.73 g stored in polyethylene tanks and fed experimental diets for 52 days (four treatments and three replicates). Biometric measurements of shrimp were carried out in two periods of 15 and 21 days. At the end of experiment results showed that the average final weight of shrimp fed the UFA binder is significantly lower than other treatments (p<0.05). Specific growth rate at three sampling periods (p<0.05) and at the end of experimental (p<0.01) was significantly affected by the type of binder, with the lowest SGR in UFA and highest in shrimps were fed control diet. Statistical analysis showed that chemical body composition of shrimp was not significantly affected by dietary treatments. In general, according to the results of diet stability, growth performance and feed utilization as well as shrimp body composition, corn starch is a good binder for whiteleg shrimp feed.

One of the significant elements in the formation of narrative structure is the sequence of its events which is explored under the umbrella term of temporal element. Abbas Maroufi’s novel Peykar-e farhadis a work in which real and imaginative times are what narrative is based upon. The novelist relates, in the novel’s surface structure, one single story in three different temporal frames, yet breaks the narrative linearity, so that for the most part the existing relations and temporal order of events remain obscure and, consequently, time, losing its quantitative value, fades away in the narrative. The current paper attempts to survey the order of events and narrative temporality in addition to studying how the author, by deploying some features of stream of consciousness, has narrated the mental structure as well as confusion of the novel’s female character. These features range from temporal and spatial turbulence, free association, author’s textual removal, and assigning a role to the reader in narration act due to direct displaying of disturbed subjectivities as well as uncensored stream-of-consciousness memories—being the same as pre-lingual mental layers—to utilizing internal monologue and soliloquy in some parts of the story, poeticness, mental obscurity and difficulty of finding the decisively right meaning for the novel with the purpose of developing a particular narrative technique.

In this paper the reflection coefficient of electromagnetic wave incidence on the walls of the buildings and obstacles that occurs in mobile communication path was modified by solving the Riccati nonlinear equations. For this purpose, the building walls are assumed inhomogeneous layers where their permittivity changes as function of the wall thickness. Using this reflection coefficient, a new propagation model based on urn and GID (uniform geometrical theory of diffraction and geometrical theory of diffraction) for multiple diffraction paths is proposed. Using this model, the diffraction loss as well as the path loss for a row of buildings with two in homogeneous faces is calculated and compared with measured data. Comparison of theoretical and measured results reveals that the modified reflection coefficient can adequately predict the reflective properties of the building walls. Moreover, results obtained with the proposed UID model are in good agreement with the measurement data. Therefore, the modified reflection coefficients well as the new UID model can be used for estimation of multipath signals strength, diffraction loss and also path delay in ray tracing algorithms used in mobile communication, radar and radio links.

Introduction
One of the centers of regional crisis is Afghanistan in the east of Iran. This country has common cultural, social, religious and political structures with Iran, but due to the weakness of political structures, it has been the center of geopolitical competition of regional and global powers. Due to its geographical proximity on the one hand and the competition of the powers, it is one of the geopolitical regions that can have many effects on Iran's regional actions. Therefore, Iran is bound to play a geopolitical role in this region. One of the most important reasons for the importance of Iran's role in the East, especially in today's Afghanistan, is activities of the groups that are religiously sympathetic to the Taliban. Therefore, national interests require Iran to prevent these groups from approaching radicalism through regional de-escalation. During the sanctions period, the Afghan market is one of the main markets for Iran's exports, the dependence of Sistan and Baluchistan province in eastern Iran on Hirmand River can be better achieved by maintaining the relationship with the Taliban, and finally, being present in Afghanistan prevents the country from turning into the backyard of Iran's regional and extra-regional rivals.

Methodology
The research method is applied in terms of purpose and is descriptive-analytic in terms of method and nature. Data gathering procedure is based on library findings. The statistical population of the research consists of experts and professors of the university and fields related to geopolitics, geostrategy and geoculture, and the sample size was determined based on Cochran's model of 50 people. In order to analyze the findings, the average test was used in SPSS software.

Results and discussion
The factors of Iran's role-playing in the geopolitical region of the East with an emphasis on Afghanistan are subject to relevant factors and variables at three internal, regional and extra-regional "global" levels. In this context, the ambiguous future indicators of power in Afghanistan and Iran's capabilities in playing its role, ethnic diversity in Afghanistan and the Pashtuns' role in power and the roles played by the Islamic Republic with regard to its civilizational characteristics in Afghanistan and playing a role, the Islamic Republic of Iran is considered as one of the main and most important factors in the geopolitical region of the East in terms of building universities and scientific centers in Afghanistan and Pakistan and producing knowledge and increasing general literacy in Afghanistan, and the influencing factors. The role of the Islamic Republic of Iran in the fields of increasing the construction of cultural bases such as Basij, seminaries, knowledge centers and cultural centers, etc. is prominent. Preventing illegal immigration on the borders of Pakistan and Afghanistan has not been successful. In the context of evaluating Iran's role-playing achievements in the direction of securing the national interests of the Islamic Republic of Iran in the East, 12 indicators were presented, and the results showed that factors such as Iran's achievements in solving hydropolitical disputes with Afghanistan, Iran's achievements in the construction of the Chabahar Free Zone, Iran's achievements in the field of spreading the Persian language in Afghanistan and Iran's roles in preventing the spread of the Salafist ideology of Arab countries such as Saudi Arabia are the most achievements for Iran in the East, and finally factors such as Iran's role in preventing the transit of narcotics on the borders of Pakistan and Afghanistan and Iran's role in preventing arms smuggling in the borders of the peripheral east are not considered as the achievements of the Islamic Republic of Iran in the peripheral east.

Conclusions
The results showed that Iran's role-playing in the geopolitical region of its peripheral east, with an emphasis on Afghanistan, will be subject to relevant factors and variables at three internal, regional and extra-regional "global" levels, and the greatest share of this role-playing includes extra-regional factors. Also, factors such as Iran's achievements in the field of settling hydropolitical disputes with Afghanistan, Iran's achievements in the field of establishing the Chabahar Free Zone, Iran's achievements in the field of spreading the Persian language in Afghanistan and Iran's roles in preventing the spread of Salafist ideology in Arab countries such as Saudi Arabia will bring the most achievements for Iran in its peripheral east.

Abstract:
This research analyzes the term “soul”, one of the magnificent secret codes in Shams’ sonnets; the eternal masterpiece created by Jalal-Eddin Mohammad Balkhi. Through using the diverse functions of ‘soul’ in this analysis, the variety of its meanings are perceived and the transcendental path of this concept is known. The perception of the different concepts of ‘soul’ takes place in three steps; in the first stage the lexical concept of soul is perceived through the relation existing among synonyms, antonyms and symmetry. In the second stage, the perception of the concept of ‘soul’ happens through its attributes and adjectives. And finally in the third stage the concept of ‘soul’ is perceived by figures of speech; simile, metaphor and symbol. The authors then have studied the concept of ‘soul’ throughout the great poetry book; making an attempt to elaborate and express the concealed concepts underlying it; trying to show how ‘soul’ goes beyond a mere lexical function and finally reaches a symbolic stage; while this study shows the concepts and traits of meanings it bears within each stage.
