The wide variety of ethnic groups and cultures in Iran has been a great advantage for this country, providing a rich substantial culture and a lively society. However, this variety and multiplicity has sometimes been used by the country's enemies as means for engendering the national identity and unity. Ferdowsi's Shahnameh, due to its richness and profundity, can play its traditional role of providing national identity and unity. In order to demonstrate the significant role of Shahnameh in providing Iranian groups with a single national identity, we considered the effect of Shahnameh on naming the geographical phenomena in Ghorveh with four towns and twelve rural areas. This research, registering geographical names and being impressed of Shahnameh, prevents this national unity from obliteration.

Abstract
Child sexual abuse is one of the social problems that has devastating effects on various aspects of children's personality. In this article, an attempt has been made to examine the psychological consequences of sexual harassment in related to children. The main purpose of this study is to identify the psychological, behavioral, cognitive and emotional consequences of sexual victimization of children under 15 years of age among those referred to four social emergency centers located in Tehran province.
     In this research - which is quantitative in terms of type and descriptive-analytical in terms of method - First, different indicators were selected as the effective factors of sexual victimization and each of the selected data was entered into the statistical tables using the available sampling method and using the researcher questionnaire. Then, the relationship between the variables was measured using statistical tests and the correlations were analyzed.
     The results of the analysis of child sexual abuse cases referred to the social emergency confirm that there is a significant relationship between child sexual abuse and subsequent mental disorders. Hypothesis testing suggests that sexual abuse has psychological, behavioral, cognitive, and emotional consequences for children's personality. Due to the need to identify these factors in order to prevent the occurrence of psycho-behavioral disorders afterwards and increase ways to eliminate or reduce it, early detection of child abuse, intervention, treatment and prevention of horrific complications of child abuse seems necessary.

In order to study the role of Pythium species associated with cantaloupe root and crown rot, samples were collected from infected fields in different areas of Khorasan Razavi province during 2009-2010. The Root pieces were washed and cultured on CMA-PARP medium. The pythium isolates were then purified by hyphal tip method and identified based on van der Plaats-Niterink mycological key. The pathogenic species were identified as Pythium aphanidermatum, P. ultimum var. ultimum, and P. deliense. The pathogenicity of isolates on cantaloupe seedlings was tested under greenhouse conditions by using wheat grain inoculum. The results indicated that P. aphanidermatum was the most prevalent species and was recovered in all the regions. P. ultimum was isolated from Neyshabour, Fariman and Mashhad whereas P. deliense was detected in Khaaf. This to our knowledge, is the first report on occurrence and distribution of Pythium species causing root and stem rot on cantaloupes in Khorasan province.

Myth and archetype represent the universal aspirations and ideas of human. On the other hand, they represent religious experience and exposure to Holy Existence. On this basis, the mystical narratives are the basic vehicle for development and exposure of archetypes and myths. As for symbolism, and the significance of mystical narratives, necessary to interpret for understanding their texts and to obtain narrative functions, we have surveyed three authentic and effective texts of Attar`s Tazkarat-ol-Olya, Hojviri`s Kashf-ol-Mahjoob and Goshairieh’s Resaleh with mythology approach. Because the mystical narratives benefit from all components of the thought and culture sphere of human, especially archetype, we have reviewed, classified and decoded, according to the their texture, have archetypes such as tree, mountains, caves, animals, colors, cycle and center, the names and numbers in the mentioned three texts. This review illustrates that mystical narratives like other areas of human thought, benefit from myth and archetype to achieve its objectives and functions as one of the dominant elements. Based on these features, many mystical narratives use narrative folk or close to their structure. Archetype and myths explain religious experiences in mystical narratives, which are covered in symbolic forms. Although mythological elements have a bond with Holy Existence, they take distinctive color and odor to the mystical narratives, and describe and three stages of birth, death, and rebirth, and encounter with Holy Existence.

Abstract
Research subject: Due to the drought and lack of water resources, many efforts have been made to store water properly recently. Using of multilayer polyethylene tanks is an efficient measure in order to solve this problem and it has received considerable attention. Proper manufacturing conditions will greatly improve the strength of these tanks and their applications.
Research approach: In this study, the effect of cooling process on the final properties of polyethylene tanks prepared by rotational molding method is investigated. Three different cooling methods comprised of cooling with water, cooling by air, and quiescent cooling is selected and their mechanical and thermal properties were investigated.
Main results: The results of the tensile test show that as the tank is cooled faster, the elongation at break will be higher. It is also demonstrated that the air cooling method results in the lower elongation at break. The results of the thermal properties show that higher cooling rate creates thicker crystals in the fragment which requires higher energy to overcome these thick crystals. According to the results of the thermal properties and using the softening temperature test it is found that by increasing the cooling rate, the softening temperature will be increased as well which will improve the application of the tank in high temperature conditions. Melt flow rate and density tests are also performed to confirm the results of mechanical and thermal properties, respectively. Charpy impact test is performed at ambient temperature to confirm mechanical behavior induced by crystal structure. All in all, cooling by water performs better than other methods in terms of mechanical and thermal properties.

In this research, biodiesel was initially produced from waste vegetable oil by transesterification reaction. The main properties of this fuel were compared with the ASTM D-6751 standard.then, performance of MF-399 tractor engine was tested and evaluated by using 5 to 25 percent biodiesel and diesel blends. Test results showed that, the power and torque of MF-399 tractor engine were increased, using biodiesel and diesel blends. This is because of good combustion of biodiesel due to high oxygen content of this fuel. There was also a slight increase in the fuel consumption and specific fuel consumption of biodiesel and diesel blends due to low calorific value of biodiesel. Results show that the B5D95 blend has the best performance and the lowest increase in specific fuel consumption among the other blends. The fuel consumption and specific fuel consumption of B25D75 was lower than the B20D80 blend. Therefore, if the goal is using high amount of biodiesel, B25D75 blend is recommended for use in MF-399 tractor engine.

Pistachio is a major agricultural export commodity in Iran. Nowadays, it ranks first among Iran’s agricultural exports. This paper focuses on the comparative advantage in pistachio production and the export market in Iran. A policy analysis matrix (PAM) framework and revealed comparative advantage (RCA) index are applied to 2000-2004 data to study Iranian government policy regarding pistachio production and export. In addition, the producer protection indices in the framework of the aforementioned matrix was calculated in order to study input and output protection policy. Results showed that Iran has a comparative advantage both in the production and export of this commodity, but the comparative advantage in pistachio production is diminishing. The RCA index showed that the comparative advantage of pistachio exports from Iran has progressed. Indices showed a high net social profitability and government protection of pistachio pro-ducers in terms of input subsidies. Then, the effects of the changing world price, exchange rate, cost of domestic factors, and cost of tradable inputs on the comparative advantage and protection indices showed that, for retaining comparative advantage in pistachio production, productivity and production costs must be both increased and decreased, re-spectively. In order to increase the productivity of pistachio, farmers should use scientific on-farm management and should employ modern production methods, and the govern-ment should develop research and development institutes.

Transfer of inheritance and accumulated savings to future generations as a factor affecting the income inequalities for the next generations and as a key variable in government expenses allocated to socio-economic services and social security has always been a controversial subject for research. In this study, using a panel data, in a structure based on traditional culture in Sistan and Baluchestan province, it is tried to determine how the households make decisions on inheritance and which social, economic and demographic factors have greater impact on such decisions in a dual urban life. For this purpose, firstly, the Altonji and Villanueva model or the "income-wealth derivative" was considered as a base framework. Then, with regard to the charitable behavior of the province households, some variables are set for the model. After that, the Data Panel for the years 2001-2006 with nearly 1600 tax cases are analyzed which are prepared through inheritance tax cases and personal visits. Then using the statistical software of STATA 9.1, data were analyzed. To determine the fixed and random effect, the Hausman test was also used. Finally, the results related to the scheme hypothesis are reviewed. Findings indicate a difference in behavior and some form of harmony respect to dual structures of each society. It means that, with improving the economic wellbeing in Zahedan city, inheritance increases, but in case of low-income societies, inheritance will decrease. In other words, Wagner theory, arguing per capita income growth from the perspective of citizens’ behavior within different structures and changes in income elasticity of goods for the households in terms of effects on the inheritance transfer model can be easily seen in different behavioral coefficients.

Due to increasing demand for the scarce available water throughout the world it is an extremely important matter, in water management, to make serious attempts in determining its true economic value. This paper discusses the optimal allocation of water to agriculture, the relatively true economic value of water as well as the cropping patterns for the Shirvan Barzo (SB) dam area in North Khorasan Province of Iran. The analysis is based on linear programming (LP) and on multi goal linear programming (MGLP) models for determining solutions that can maximize net return to farmers. In the study, the priority of goals is developmental, social, economical, and environmental respectively. The results indicated that optimizing the cropping patterns along with proper the allocation of irrigation water has yet substantial potential to increase the net return from agriculture. It has already decreased the applied water as much as 19 percent. The results show that the economic value of each unit of agricultural water is estimated to be between 107 to 1296 IRR×104 per cubic meter. This suggests managing the allocation of water based on optimal models and bring water prices close to its true economic value to motivate the farmers to economize in the applied water.

In this article, fracture toughness of austenitic–martensitic functionally graded steels fabricated by electroslag remelting with crack arrester layers is investigated by experimental and analytical methods. The material contains austenite phase in addition to martensite layer. The Young’s modulus and the Poisson’s ratio have been assumed to be constant, while other mechanical properties like the yield strength and the strain hardening exponent vary exponentially along the specimen width. In analytical case, unloading compliance method is modified to calculate the critical value of J-integral for cracked three point bend specimens while standard specimens with different crack lengths are tested in experiments. The effect of crack length on the fracture toughness has been studied. It is observed that, as the crack tip goes toward a martensite layer, fracture toughness of the specimen decreases considerably. The obtained results from the proposed model are in good agreement with the experimental results.

In this article, using two criteria of rivalry and excludability, the direct production factors are classified as physical capital, human capital and technology. Based on the new theories of economic growth, essential role of human capital in innovation, adoption and application of new technologies is emphasized. Then to explain differences of economic growth across countries, institutions as the fundamental causes of economic growth are discussed. It is argued that institutions provide circumstances in which proximate causes of production are accumulated and used. Institutions signal to the economic agents to pursue productive or rent seeking activities. In this regard, paradoxical findings of empirical studies as to effects of human capital on economic growth are analyzed. Using a cross-section data, based on 10-year average of output per worker for about 90 countries over the period 2001-2010, the interaction effect of human capital and institutional quality on growth is evaluated. The main implication of the model for Iranian economy is: Notwithstanding the huge investments in human capital, which mainly financed by oil revenues, low quality of institutions has led to slow economic growth.

Objective: Titration of viruses is important to determine the quantity of virus in vaccine development, master virus seed stock preparation, viral vector studies and virus replication. In this study, we compared the CCID50% and plaque assay as a standard titration method for rotavirus (RF) and HSV-1.   Methods: The MA104 and Vero cells were inoculated by RF and HSV-1 in 6- and 96-well plates. Following infection and adsorption, the optimal time for the cytopathic effect caused by the viruses was noted and the results compared. Results: The CPE (Cytopathic Effect) of RF was observed in less than 18 hours, which increased until 72 hours after inoculation. In HSV-1, the CPE was observed 24 and 72 hours after inoculation. The virus titration in the plaque assay was monitored at 96 hours post-infection for RF and at 72 hours post-infection for HSV-1. In both viruses the plaque titer method was lower than the CCID50 method, since the results indicated that 1 CCID50% was equal to 0.7 PFU. Conclusion: The plaque assay is one of the most accurate methods for viral titration. For the plaque assay, individual lesions may be isolated, which the plaques can be counted. The CCID50% method is not applicable for purification of homogenous viruses, nor is this technique reproducible.

Objective: Group A rotaviruses (GARV) are responsible for the vast majority of severe diarrhea worldwide that kills an estimated 600,000-870,000 children annually. Since infantile gastroenteritis is a main health problem, therefore diagnosis and treatment of this disease is crucial. Gene rearrangements have been detected in vitro during serial passages of the virus at a high multiplicity of infection (MOI) in cell culture, as well as in chronically infected immunodeficient individuals. In this study, we developed an RT-PCR method to detect and diagnose the standard and gene rearranged bovine rotavirus. Methods: Rotavirus RNA was extracted from confluent monolayers of infected MA-104 cells, stained with silver nitrate, and then electrophoresed in a 10% polyacrylamide gel. The full-length gene products that encoded the NSP1, 2, and 3 genes of the standard and rearranged rotavirus were amplified by RT-PCR using specific primers. Results: We observed rearranged NSP1 and NSP3 genes that had different migration patterns seen with polyacrylamide gel electrophoresis. NSP1, 2, and 3 gene segments from standard and rearranged rotaviruses were amplified by RT-PCR, then the complete nucleotide sequence of each gene was subjected to sequencing. The results showed the generation of gene rearrangement through serial passages of the bovine rotavirus RF strain. Conclusion: Serial passage of rotavirus in cell culture at a high MOI and chronic infection in immunodeficient target groups might alter rotavirus evolution. The methods utilized for detection and characterization of rotaviruses are continually evolving and being refined. Data collection is necessary to understand the molecular and antigenic features of the rotavirus in order to have a successful implementation of rotavirus studies and the development of a rotavirus vaccine. This study shows the importance of genetic variation and can provide valuable information about the amplification, diversity, biology, and evolution of rotaviruses.

In this paper, thermal and vibration response of cross-ply bi-stable composite laminated plates were studied using semi-analytical, finite element and experimental method. In order to evaluate the semi-analytical and finite element results, a bi-stable composite plate was manufactured using a special procedure. Next, geometrical characteristics and displacement of different paths on the plate were measured experimentally at room temperature. In semi-analytical approach, the two stable states and the first natural frequency of cross-ply laminates are calculated based on Rayleigh–Ritz approach combined with Hamilton’s principle. In this study, a modified shape function was introduced that allows the curvatures to vary in both longitudinal and transverse directions. Using the modified shape function, the displacement of the plate in its stable configuration and the first natural frequency of the plate can be more accurately predicted in compared to the Hyer’s shape functions. The obtained results from the proposed shape function are in good agreement with the finite element and experimental data. The proposed shape functions can also be used in dynamic and vibration analysis to determine the snap-through load of the cross-ply laminates.
