Abstract
Introduction: Nowadays, Tehran is the most important challenge of political management of space in Iran due to the accumulation of problems in natural and human dimensions. The most important dimensions of this challenge are population density and the lack of coordinated management to overcome this problem and its consequences. Since one cannot consider Tehran separated from far and near hinterland, the first issue is the lack of spatial/geographical justice in these hinterlands. Tehran's problems can be analyzed in three levels: physical-residential, regional, and national. This descriptive-analytical research was carried out based on library resources with the aim of analyzing spatial justice in Iran and organizing political space in Tehran.
Conclusion: The lack of spatial planning and sustainable development approach on the national, regional, and local scale in the Iranian planning system has, above all, resulted in intense centralization, institutionalized, and has led to the formation of the center of the periphery pattern in the country. The performance of development programs, before and after the revolution, has led to the imbalance of the governing pattern of the spatial structure of the country. Also, the spatial/geographical injustice in the country and consequently in Tehran province, as well as the lack of integrated management in Tehran's urban management have caused Tehran's current problems. In order to solve the problems of Tehran and its optimal administration, it should be planned based on the available resources with the fair spatial planning approach to space and in the framework of the spatial planning strategy, using the space justice in three short, medium, and long periods, in order to provide the optimal administration of Tehran.

Indo-european worldview has been reflected considerably in the formation of the Persian poem and prose, because of its literary and contextual grandeur. It has affected many works in various aspects, so that its mythology has been used in the prominent works such as Firdausi's Shahnameh and the Kyrgyz epic of Manas. However, the way of possessing such a worldview by Shahnameh and Manas is the subject of current research. In this regard, we have described and considered the behavior of heroes in the two works based on the George Dumezil's Three Functions Theory. Our study reveals that the tree functions of the theory have been applied all over the stories of these two epics. This theory is based on the two vises: coordination and contrast; meanwhile Shahnameh and Manas are based on goodness and evil, which are symbolized in heroes such as Siavash/Bakai as well as Rostam/Manas. The first section consists of the wisdom, intellect and calmness symbols, and the second section is related to the symbols of violence, stringency warmness, militancy, and self discipline; while ordering the Quadruplet elements system, provides the people with peace and self-coordination by its force. Moreover, there are invulnerable Demons and Personages in both epics such as Esfandiar (in Shahnameh) and Malgun and Mady Khan (in Manas). However, their only vulnerable spots are their eyes through which they must be killed and their dominance must be ended. This is the motif of “Killing the Demon by blinding him”, which forms one of the worldview's elements mentioned in Indo-european mythology.

Presence of filler in the polymeric materials changes the mechanical, dynamic-mechanical, rheological properties and even the swelling behavior of rubber composite due to mechanisms such as hydrodynamics, polymer-filler and filler-filler interactions. Swelling in rubber composites directly affects the polymer chains, also can affect indirectly other structures in composites such as the filler network and reduce mechanical properties suddenly. In this study, the nitrile rubber-nanosilica composite containing different concentrations of modified nanosilica was prepared and the composite structure was studied through rheological, mechanical, dynamic-mechanical tests. Also it was found that the filler network containing over percolation threshold 13phr of filler concentration has a significant contribution to the mechanical properties of composites. To determine the swelling effect on the prepared composite structure, with different degrees of solubility were used. The mechanical properties of the samples were measured in equilibrium swelling state for each of the solvents The decrement of the mechanical properties between the dry samples and swelled ones containing 14.4, 20 and phr 6.25 silica in solvent with 15% toluene is significant. These intensive changes in mechanical properties that happen at the low degree of swelling are attributed to the removal of the filler network. Therefore, controlling the swelling of rubber parts in adjacent to the solvent, plays the fundamental role in their performance.

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.

In this study, first using documentary research method, the nature of language in the web-based electronic communication, besides different methods of improving communicative and linguistics competence in teaching languages online, were investigated. Then considering the importance of language faculties' familiarity with the role of computer-based teaching in the development of linguistic competence and communicative skills necessary for translating or teaching all foreign languages (esp. Persian to non-natives), a descriptive survey method was used to investigate the familiarity of foreign language faculties with the strategies and technologies used in e-teaching-learning process applied in teaching languages online. The results of the 68 questionnaires filled in by English, French, German and Persian faculties of seven universities offering classical and virtual programs indicated that most of language faculties are not familiar with web-based strategies and techniques in teaching or learning foreign languages. Considering the need of our country for the experts who are able to communicate with the scientific scholarly networks in the world to obtain or transfer related knowledge and those who are able to use at least one international language of their fields thoroughly, planning an online faculty training program can be an essential measure to improve teaching or translating foreign languages at the academic level and also lead Persian language to find its proper position in the cultural, educational and scientific world networks.

Research subject: The sensitivity of electrical conductivity of rubber/conductive filler composites against swelling strains is a phenomenon that can lead to the creation of sensors to detect the type or leakage of hydrocarbon liquids. In the swollen conductive composites, the variation of filler network structure reduces the Statistical frequency of the tunneling and interconnection of conductive particles. This behavior can be a sign for a solvent or hydrocarbon fuel detector system in a flexible sensors.
Research approach: In this study, nitrile rubber/graphite composite samples with several concentrations (20, 30, 40, 50, 60, 70 and 80phr) of graphite particles were prepared and their electrical characteristics were measured. The changes in the electrical resistance of nitrile rubber /graphite samples were investigated based on increasing the content of graphite particles, immerse to toluene, and repeating the period of the swelling/recovery process for each sample.
Main results: The sensitivity of composites with higher concentrations than the percolation threshold (53.5phr of graphite particles) to the conductivity changes due to the swelling phenomenon is appropriate for use in the sensor. Also, incremental changes in the electrical resistance of the samples immersed in the toluene solvent were measured and it was observed that all the samples were eventually converted to electrical insulation. In order to study the repeatability performance of sensor, samples with 60, 70 and 80phr of filler were swelled and recovered for three periods, which is less than the conductivity of the sample before the second and third swelling process compared to the conductivity before the first one. This difference is very small in the sample containing 80phr of graphite particles. The trend of change in electrical resistance is significantly different in the second swelling process compared to the primary swelling. But there is little difference between the third swelling process and the second one. This phenomenon has occurred for all three samples, which can be observed to be similar to Mullins effect.

Rearing methods for Bracon hebetor (Say) (Hym., Braconidae) were investigated in the series of laboratory experiments designed to enhance the yield of the mass rearing of this parasitoid for biological control of lepidopteran field and stored product pests. In these experiments, the effects of parasitoid and host densities on fertility and sex ratio of B. hebetor were assessed. In parasitoid densities, 50 last-instar greater wax moth (GWM) Galleria mellonella (L.) larvae were placed per container and 1, 2, 4, 8 or10 pairs of B. hebetor (one male and one female) were released in each container. In host density study two pairs B. hebetor were introduce in six different densities (10, 20, 30, 40, 50 and 60) of host, GWM per container. A density of ten male-female pairs of B. hebetor produced a higher number of progeny (205 ± 7.07 adults) on 50 last instar larvae of GWM. Similarly, in a host density experiment, a density of 60 last instars GWM larvae produced a significantly higher number of parasitoid progeny (142.0  ±  8.75 adults), followed by 50 last instar larvae (141.0 ± 8.34 adults) among the tested host densities when two pairs of B. hebetor were used. The sex ratio of progenies was male-biased in all studies and there were no significant effects on sex ratio in various parasitoid and host densities. In mass rearing experiment, total number of emerged parasitoids per 200 wax moth larvae was 1091 ± 82.38 adults with mean parasitism rate of 98 ± 0.8%.

ntroduction
Since about a century ago, Iranians have been careful in facing the social developments of other nations and the implementation of the "development" paradigm in Iran and third world countries. And gradually their thinking has reached a degree of maturity to start an official effort to replace this paradigm.
A review of Iran's social history from 100 years ago until now, clearly indicates that Iranians have continuously observed the social developments of other nations and with the coming of the Pahlavi period, they witnessed profound spatial changes in Iran.
These developments took an organized form especially during the second Pahlavi period, and many programs were prepared in the field of administrative organizations, buying satellites, establishing a nuclear power plant, building big dams, creating a modern army, etc. The implementation of these programs in several decades was followed by a national review of what had happened. The general understanding of the society based on the emotional wisdom of what had happened can be summarized in a few basic points.
What has happened is pushing Iran towards a country with mass consumption and leading to dependence on foreigners.
The class gap and the population of the poor have increased drastically every day.
Nomadism and muralism are in danger of extinction
Environmental vulnerability has become a serious problem
Iran's cultural and historical identity has been exposed to destruction and its major change has manifested as a fundamental attack )Crossing identity, history and security(.
Theoretical foundations and objectives:
This article followed a comparative logic and mostly analyzed the differences between the development and progress paradigms. Also to run the progress paradigm it is tried to benefit from the executive structures of the development paradigm
Methodology
In order to achieve the goals of this research, at first, the bases and foundations of the development paradigm (Rusto in America), the land use paradigm (the French and the Germans) and the regional foresight paradigm (the European Union) in terms of epistemology are investigated, and according to the definition of paradigm according to Cohen, the semantic variables of each paradigm are indexed. The semantic variables defined for each paradigm were:

• The Hometown  of paradigm

• The Doctrine of paradigm
• The goals of paradigm
• The final destination of paradigm
• The executive subsystems of paradigm
• The ideological contexts of paradigm

After recognizing each of the semantic indicators of the paradigms, the recognition of these semantic indicators was discussed in the paradigm of progress. This work was done based on the latest version of the Paradigm of Progress document at the Iranian Islamic Pattern Center. In the next step, to compare these paradigms with each other, “Nich method” was used to calculate their spatial distance. The degree of difference of each in the field of Hometown, Doctrine, and Goals was determined. This comparison has followed “Jeanette's method” of analysis.
Findings:
Investigations showed that the four paradigms in spatial planning have sometimes fundamental differences in terms of Hometown, Doctrine, and Goals. These differences in their Hometowns, Doctrines, and Goals are different from what is discussed in the progress paradigm of Iranian society, and therefore, a review of the theoretical foundations of social and spatial evolution in Iran requires a serious revision.
Conclusions:
For the implementation of any paradigm, three systems (scientific-philosophical, governance and cultural) are necessary Which can generally be summarized in the following cases:
Borrowing the executive organization of the "development" paradigm is one of the valuable experiences, the use of which can reduce the fifty-year period of the progress paradigm to one or two decades.
Certainly, the implementation of the progress paradigm cannot be implemented without having three systems of "governance", "scientific" and "cultural", and this is the most important achievement of the development review and international experiences of several decades in the development paradigm.
In the field of philosophical and scientific system, although the combination of the field knowledge and the university is a suitable combination, but the change in the content is necessary both in the field of knowledge and in the university. Iranian scientists and researchers in both areas should define indicators that can continuously and intelligently evaluate the paradigm elements and the extent to which they have been achieved.
In the realm of culture, the tricks and techniques of the evangelists are very rich and only updating them and their form of presentation should be adapted and updated according to the taste of today's societies. In this matter, the main axes of the norms of the progress paradigm should be placed in the agenda of the cultural trustees and help in all processes that can transform these norms into social behavior at various scales.

A honeycomb panel consists of an array of open hexagonal cells which their walls are perpendicular to face sheets although other panel sandwiches don’t have these perpendicular walls. Their design is often performed based on minimum weight. This research is aimed at minimizations of weight by means of computing honeycomb core girth. Weight optimization is done by means of Naive and numerical procedures. Numerical optimization is done by the sequential quadratic programming (SQP) method. Geometric parameters and optimized weight are calculated for hexagonal and square cells. Optimized weights for these two cross-sections are compared. Keywords: Honeycomb Weight Optimization, Sandwich Panels, Numerical optimization, Sequential Quadratic Programming.

Radiative heat transfer must be considered in retail refrigerators with glass doors. Some methods have been proposed for reducing radiative losses, like usage of double glased windows filled with argon or other types of transparent material with low emissivity in infrared band. For evaluation of thermal radiation in commercial refrigerator compared to infiltration loss, thermal conduction and facilities loss, a three dimensional model has been developed. In this model all wall surfaces are isothermal and evaporator with specific temperature located in roof. The radiative properties of glass are considered as actual. The results show that decreasing internal temperature of cabinet incentive radiation losses. These losses are almost independent of window surface temperature. Increasing of emissivity factor of evaporator, causes increasing of thermal radiation flux of evaporator which can be used in design improvement. Radiation flux of each surface have been compared with convection flux. This comparison show the importance of covering windows in unutilized times.

Backgrounds: Syzygium aromaticum L (S. aromaticum, clove) is a plant species belonging to the Myrtaceae family. It is cultivated in many African and Asian countries. Folk medicine practitioners use different parts of this plant to treat gastrointestinal problems, diarrhea, dental pain, ulcer, and other chronic diseases. Experimental data on phytochemicals and pharmacological activities of this plant are scattered or unsystematic. Therefore, this review aimed to explore the available data on phytochemicals and pharmacological activities of S. aromaticum essential oil and extracts with various polarities.
Materials & Methods: The literature review showed that only a few studies were conducted on this plant; consequently, there is not enough documented information about its bioactive phytochemicals and pharmacological activities.
Findings: Most previous studies reviewed reported significant bioactive phytochemical contents, namely eugenol (49.7%), caryophyllene (18.9%), benzene, and 1-ethyl-3-nitro (11.1%), along with minor amounts of phytochemicals including carotenoids, gallic acid, flavonoids, oxalic acid, tannins, amino acids, fatty acids, and cyanidin glycoside. Sugars, coumarins, oleanolic acid, saponins, glycosides, and lipids were also identified in this species. The methanol extract of this plant and its different polar fractions were shown to exhibit significant antimicrobial, antioxidant, anti-allergic, antidiabetic, antihypertensive, anti-inflammatory, antifungal, and anticancer activities. Furthermore, the plant extracts were also shown to have chemoprotective and hepatoprotective properties.
Conclusion: This review provides comprehensive data on botanical aspects, phytochemicals, and pharmacological activities of this plant to researchers to explore traditional/ medicinal uses and commercial drug production from S. aromaticum.

Nowadays, the effect and importance of housing and its role in Iran’s economy cannot be underestimated. Housing as a fundamental and basic need for Iranian households is not just a shelter, but is considered as a crucial asset. It has a superior financial value as well. Expansion in urbanization, especially in Tehran, regarding its financial and political importance has contributed to this situation. In this paper, using time interval data between the years 1981 to 2005, the casual relation between variables which affect housing in urban districts through analyzing and monitoring Granger-Hissao, Simes causality test, have been utilized and its impacts are examined in self-regression model. The results indicate that there was a causality relation between price of house, bank loans, number of households and their incomes. Nevertheless, house price had the most impact on instabilities of housing during this period.

The waste produced by households, industry and factories to use as wash water and cooling systems and equipment, is caused environmental complications. Waste created a suitable environment for the growth of odor and pathogenic bacteria. This study aimed to isolate microorganisms in the wastewater and use them for the reduction of BOD (biochemical oxygen demand) and COD (chemical oxygen demand).The samples were collected aseptically from different parts of wastewater of herbal distillation industry. The bacterial strains were isolated from the samples in LB media. The isolates were distinguished based on the morphology and biochemical characteristics. Among the total 69 isolates, four isolates were selected to measure the ability to reduce BOD and COD and added to the waste water. Reduction of BOD was measured using BOD meter. Also, COD was determined by titration method. The isolates were identified by biochemical tests. The amount of BOD and COD reduction after adding selected strains to wastewater was 47.43 - 71.82% and 44.79 - 56.5% respectively. Also, the consortium of bacterial strains showed better ability to reduce BOD and COD (38.32-57.29%and 76.6-83.21% respectively). The results determined that wastewater contains bacterial strains which have shown significant reduction in BOD and COD and organic matter decomposition in wastewater and reuse it in agricultural and industrial sectors. Therefore, we can use these bacteria for wastewater treatment.

The present Research has surveyed the foreign policy of the Islamic Republic of Iran vis-à-vis the Republic of Azerbaijan. Based on some of the most important geographical and geopolitical realities that exist between the two states, by presenting one main question and two hypotheses, used as guide into a thorough geopolitical assessment of the issue. Based on the findings, we come to this conclusion that the none-cordial disposition of the Republic of Azerbaijan towards Iran, and some of the uncharted pasturings and unspecified strategies by the Islamic Republic of Iran render ineffective so many positively positoned areas of common geographical and/or geopolitical interests such as territorial contiguity, common religious tendency (both Shiite), common ethnicity, common economic interests (agricultural and irrigation possibilities), common cultural and historical backgrounds. Unfortunately, the continued policies between the two states have further made all these possibilities to render ineffective. The main outcome of the research shows that some of the issue are resultant from a suspected nationalistic disposition on the part of the Iranians; and similarly, a persistent attitude of none cordiality from the Azeris. Moreover, the Republic of Azerbaijan has yet to present a logical and pragmatic reason to explain its negative diplomatic strategy against the Islamic Republic of Iran That could justify its distrustful policy towards iran. The research consequently has proposed the following general aims and strategies to be implemented in Iran’s faring policy towards the Republic of Azerbaijan: General aim: the faring policy of the Islamic Republic of Iran in relation to the Republic of Azerbaijan is determined by geographical and geopolitical realities that exist between the two states. Strategy: to develop mutual relations based on the need for neighborly dispositions, to understand the geopolitical dictates of time and space, common national interests and aims,economic cooperation,and to explore other avenues that would develop mutual trust in order to broaden cooperation between the two states.

In this paper, it is tried to propose a robust model for predicting inflation in Iran among alternative models. For doing this, monthly data from April 1990 to the end of September 2009 is used. Firstly, it is tried to determine whether the CPI data is chaotic or stochastic. It is shown that it is chaotic rather than stochastic. Therefore, it is predictable. Then, a stochastic differential equation model is estimated (specifically a geometric Brownian motion) for CPI in Iran. In order to compare the prediction power of the model other alternative models of prediction like ARMA, non-linear GARCH, EGARCH, TGARCH are also used to extrapolate inflation during a six month prediction period. Based on RMSE, MAE, U-Tail, it is revealed that stochastic differential equation model is much more robust than the alternative models mentioned above.

Nowadays, the issue of service quality for service-provider organizations specifically banks is of considerable importance. The service-provider organizations (specifically governmental banks) are aware from the necessity of getting satisfaction of customer and assessing quality of services. In this research, we evaluate and analyze the gap of expected and current service quality. In fact, the gap between customer´s expectations of bank services and customers perceptions is assessed based on the hierarchical service quality model (HSQM), which has been introduced by Brady and Cronin in 2001. To do this, customers of Keshavarzi Bank are given as statistical population and a sample with 384 people is extracted from Tehran Keshavarzi Banks using Krejcie-Morgan Table and Cochran formula. The results show that just in two dimensions of HSQM namely «waiting time» and «valence», there is no significant difference between expectations and perceptions, but there are gaps among expectations and perceptions in the other dimensions.
