Abstract
Due to ethnic, religious and cultural diversity, Zahedan has a heterogeneous and diverse population. The diversity of religions and denominations from the formation of this city until the Islamic Revolution has never been a matter of dispute and peaceful coexistence between different religious groups has been established in this city. After the victory of the Islamic Revolution and the continuation and emergence of Shiism as the official religion of the country, the Baluch people, due to differences in religion, became less integrated with the central government than the Sistani's and became more and more isolated in identity. The objective manifestation of these gaps can be seen in the most symbolic religious element of the city, namely the Makki Mosque. The hidden signs in this mosque as an arena to show the ethnic-religious hegemonic power of the Sunni Baluchi's, with unusual dimensions and heights and unfamiliar forms and decorations, have dominated their surrounding context and produced special semantic rules. In the face of such a situation, the narrator of the Makki Mosque has experienced signs of apathy because the signs used in this mosque have acted in disconnection with the previous meanings of the Baluch mosques and have become an unfamiliar text for the narrator. Finally, the Makki Mosque has provided an opportunity to represent concepts and issues that can take us deeper into the Baluch cultural layers and provide a relatively deep understanding of the people's situation in contemporary society.

Abstract
The Historical Ashura books are historical reflections of the Ashura event and they are expressed in the form of narration. The application of new theories of literary criticism in the analysis of historical provides a better understanding of the narrative context of these works. The purpose of this study is to introduce an unknown Ashura historical book and its narratology from Todorov's point of view. This article tries to examine the syntactic level of narration in the book Sar-e-Asrar in a descriptive-analytical way. So that narratives better illustrates the narrative structure of such works. Todorov's narrative analysis is one of the most prominent structuralist approaches that deals with manifestations such as syntactic representation. According to the findings of the research, the narration with its developments, propositions, etc., which show the syntactic manifestation of the narration, has advanced the design of the narration.

Abstract
Autism is a neurocognitive disorder. Many children with autism do not have a change in language and usually tend to have literal interpretations of phrases, which makes it difficult to understand metaphorical language, which can be seen in both visual and visual metaphors. The aim of this study was to compare auditory and visual metaphorical perception in children with mild autism and normal children. The present study is a cross-sectional and causal-comparative study. The statistical sample of this study includes 30 boys aged 7 to 10 years with mild autism studying in educational centers for exceptional children in Mashhad and 30 normal children matched in terms of age who were selected by convenience sampling method. After initial language assessment, they were assessed by metaphorical perception test and U Mann-Whitney test and SPSS 23 software were used to analyze the data. The results of data analysis showed that in metaphorical perception in general there is a significant difference between autistic and normal children (P <0.001), also, in understanding visual and auditory metaphors, the two groups showed a significant difference (P <0/001). The obtained results indicate that compared to normal children, children with autism have a lower performance in terms of understanding visual and auditory metaphors, and considering this issue can be used in planning and designing educational content and rehabilitation interventions in order to improve educational performance and social benefit of these children.

Abstract
Powdery mildew (PM) of chilli is one of the major diseases affecting the yield and quality of chilli. Pathogen perpetuates in the infected crop debris and produce airborne conidia for rapid secondary spread. Prophylactic application of fungicides is admissible to keep the disease under threshold. Therefore, an experiment was designed to determine bio-efficacy and phytotoxicity of different doses of a new molecule combination (i.e KK-21: Sulphur 84% + Azoxystrobin 6% SC) along with optimization of its number of sprayings. This molecule was also compared with the most popularly used fungicides against PM of chilli. Additionally, influence of weather variables on the initiation and progression of the disease were also studied and prediction model developed by stepwise regression equation for timely forecasting and managing the disease. Study revealed, depending upon the prevailing weather the disease first appears between 44 to 64 days after transplanting then progress gradually at a rate varied from 0.0012 to 0.0139. Among the fungicides applied, three spraying of KK-21 @ 2500 ml/ha at 15 DI just after initiation of the disease was most effective with lowest disease severity index (5.00) and highest yield 150.24 q ha-1 and no phytotoxic effect was recorded even at higher dose. Result also showed, maximum temperature and relative humidity had significantly positive and negative correlation with the disease severity and the prediction equation demonstrated that these two factors could explain 78.2 - 87.6% of the variation in disease severity.

Abstract
The adjective "sustainable” is used for worldwide explanation where both human and nature can live up to their present needs, sustain the rights of future generations and protect the environment without the existence of destructive effects. Use of natural resources accordingly to provide today’s human needs and not to become dangerous for future’s human needs is the issue that leads architects to follow the principles of sustainable development. In this investigation, improving of climatic technology and use of climatic condition and natural resources in traditional architecture of Iran and contemporary architecture will be studied. It is often forgotten and even ignored that architectural traditions are rich in content, given that they have found the right harmony between the necessities of living, the environment, material resources and ideas on the use of space. Using these criteria, contemporary architecture could take a direction where cultural continuity and adaptability not only take pride place but also provide guidelines for climate-adapted and sustainable architecture. However, during the last decades, the impact of socio-economic and cultural changes on traditional environments has become obvious. Contemporary design is increasingly depending on the mechanically controlled environments in order to maintain comfort, hence, increasing energy consumption. For achieving this goal, first, the importance of climatic traditional architecture of Iran and its principles of designing will be noticed. In other words, we will find how climatic architecture can influence sustainable development by using renewable energy resources like wind and solar energy and climatic condition. In this part, the paper focuses on the role of climatic responsive design, building situation in a site and angle of sunlight, building form, building roof, interior thermal comfort and natural air ventilation. In the second part, we will study the role of new and smart technologies in achieving sustainable development goals. As we know, time is passing and human knowledge develops every day, so it is necessary to pay attention to new and smart technologies behind the climatic responsive design until we can design buildings in respect of human comfort that are conformable with sustainable development as well. So, according to revolution have been existed by nanotechnology. It is noticed to Nano smart Technology and using of renewable energies. Undoubtedly, nanotechnology can provide many opportunities for architects and engineers for enhancing the construction material and decreasing their weak points and increasing their advantages. Buildings have the main role in balancing energy consumption. Solar energy, which is known as Photovoltaic energy can provide energy without using fossil fuels. Due to the importance of photovoltaic energy for improving of the efficiency and flexibility of solar cells, they have been widely studied. In this case, Nano- technology has made some progress in providing energy from wind and sun in micro scale. The main goal of this article is to study on climate design and usage of new technologies. Climate design refers to the principles that we follow in traditional architecture, where the materials are clay and brick. However, now that the material and construction technology have been improved; the question is how we can have a conformable architecture with sustainable development?

Abstract
Plant extracts, like phytoecdysteroids, are currently studied because of the possibility of their use in plant protection. Phytoecdysteroids are insect steroid hormone analogues, and they are believed to deter invertebrates from plants, either by acting as antifeedants or by being toxic through hormonal disruption on ingestion. We describe here the effects of extract from Spinacia oleracea L. (Chenopodiaceae), a plant producing phytoecdysteroids, on the demographic parameters of Plutella xylostella L. (Lepidoptera: Plutellidae). Spinach is one of the very few crop plants which produce large amounts of phytoecdysteroids. Ecdysteroidal extracts of leaves from this plant were incorporated into food given to third instar larvae for two days. Then the larvae were reared on untreated leaves. The eggs from the emerging adults were picked up for demographic experiments. The rearing of the newly hatched larvae was continued individually on untreated leaves. All experiments were performed on 25 ± 1 ºC, 65 ± 5% RH and a photoperiod of 16:8 (L: D) hours in a growth chamber. Data analysis demonstrated that the fecundity of the females was strongly affected by ecdysteroidal extract. Values of intrinsic rate of increase and net reproduction rate decreased significantly as concentration of the extract increased. However, doubling time increased significantly as concentration of the extract increased. The present study demonstrated that the ecdysteroidal components of the spinach are effective on the demographic parameters of P. xylostella. Therefore, this extract may be potential protectants as botanical alternative agent.

Abstract
Reducing consumption of fossil fuel, is a key effort to promote sustainable development. Transportation sector is one of the most important parts of fuel consumers. Urban form is one of the most important and effective factors in fuel consumption in transportation sector. Urban form includes some criterions such as density, mix land use and internal development of city. In order to reduce fuel consumption in transportation sector, urban form should be changed. This issue is more necessary due to increasing urban population and urban sprawl. Resident’s use of private car increases with distance from city center and lack of proper public transport system. This not only causes increasing of the fuel consumption, but also it increases emission of greenhouse gases, noise pollution and traffic congestion. The present study has followed explanation of relationship between urban form and energy consumption in transportation sector. For this purpose, the theory of urban form, including compact city, transit-oriented development and Neo-traditional development and studies in other countries are surveyed and analyzed. Research findings indicate that socio-economic characteristics and physical variables and urban form are affected the usage of private car and fuel consumption in transportation sector. This study which is based on the findings of survey and analysis, seeks to develop a general conceptual framework for understanding the effective factors in Households Fuel Consumption in Transportation Sector.

Abstract
In this study, the human health risk of mercury due to consumption of croaker (Otolithes ruber) in Mahshahr, the Persian Gulf, , was evaluated using atomic absorbtion spectrophotometer)and cold vapor techniques to measure the mercury concentration in muscle samples of 30 fresh croakers . A. Result showed the average concentration of mercury in croaker muscle was 0.354±0.09 µg/ g of fresh wet weight, which was less than the allowable amount for human consumption determined by the international organizations such as USFDA and WHO, but more than the allowable amount for human consumption determined by MAFF and the USEPA. HQ Index was above 1 (1.18). In addition, the calculations indicated that daily and weekly mercury uptake for the Iranian consumers, according to Statistical Yearbook of Iran Fisheries organization (the amount consumed per capita), is lower than the guideline values (PTWI and PTDI) provided by WHO, USFDA and more than USEPA. Therefore, the consumption of the croaker might be associated with some threat to the consumer’s health particularly pregnant women, fetuses and children from mercury but consumption permitted rate of 20gper dayand138 gper week is recommended for other people.

Abstract
Background: Health care workers (HCWs) are at the risk of the acquisition of occupational transmissible diseases. Controversial results have been reported about hepatitis C virus (HCV). The main objective of the recent study was to evaluate the seroprevalence of HCV and its relationship to the occupational history and exposure of HCWs in two teaching hospitals in Tehran-Iran.
Materials and Methods: A seroprevalence survey of HCV was conducted using serum samples obtained from 1400 HCWs in two teaching hospitals during 2012. The samples were screened by ELISA for the presence of anti-HCV antibodies.
Results: In none of the participants the HCV antibody was detected. Needle stick injury was significantly higher among nurses. Younger HCWs with a shorter professional life had more frequent needle stick injury (p<0.001).
Conclusion: The seroprevalence of HCV in HCWs was considerably lower than that reported in the general population, and needs to be evaluated on a larger scale.

Semantic Space of šod-{n ‘to become’ in Persian: A Cognitive Account
This paper attempts to explore the semantic space of šod-{n ‘to become’ in Persian in order to address some basic features of linguistic cognition (e.g. analyzability and compositionality). One of the highly-frequent verbs in Persian is šod-{n, which with regard to its different functions at the level of sentence, can be considered as the most active verb in this language. According to a diachronic viewpoint, the same verbal form, šod{n, with four distinctive functions (as a main verb, as a copula, as a modal verb, and as the verbal constituent of complex predicates) plays an important role in Persian verbal system. The passive construction in Persian is considered as a Complex Predicate in which šod-{n combines with different linguistic categories such as noun, adjective, prepositional phrase and past participle (X in general).
Its semantic space indicates that various types of constructions including šod-{n form a network of meanings, in which the verbal element šod-{n is meaningful, in contrast to the previous studies it's passive construction which considered it as a purely syntactic element carrying no meaning. Therefore, the passive construction in Persian is viewed as analyzable in which šod-{n is not a random occurrence but rather an extension of its other uses. The relatedness of the uses of šod-{n provides further evidence for the claim in Cognitive Grammar that the passive construction is part of a larger network of related syntactic constructions and not derives from the active construction.

Abstract
Volunteers are an organization's most complete human resource to hold a successful sporting event. Maintaining a volunteer workforce and motivating volunteers to continue their activities is one of the most important tasks of sporting event managers. This study aimed to investigate how volunteers' involvement in the 14th Sports Olympiad for University Students in Iran affected their behavior. For this purpose, 157 volunteers present at the 14th Sports Olympiad for University Students in Iran were randomly selected as the research sample. Researchers collected data using the Zitsmal et al. (1996) Modified Scale of Behavioral Intentions, Doherty's community involvement scale (2009), and Zaichkowsky's Event Involvement Questionnaire (1994). In order to test the hypotheses, structural equation modeling was used. The results showed that the measurement model has appropriate internal consistency, convergent validity and Discriminant validity. It was confirmed that all variables used in the study were accurate. In the structural model results, the index for determining the coefficient of behavioral intentions was 0.44. Showed that social participation and event participation had a moderate and positive correlation with each other (0.40), and community involvement and event involvement, respectively, with path coefficients of 0.45 and 0.34, had an effect on behavioral intentions, so it can be concluded that understanding the psychological and behavioral aspects of volunteers, such as types of involvement, helps sports organizations in attracting volunteers. In this way, they can maximize the willingness of volunteers to involvement in the future.

Abstract
In a completely randomized design, the effects of two probiotic bacteria, Bifidobacterium animalis and B. lactis at four concentrations of 0 (control), 1×109 (T1), 2×109 (T2) and 3×109 (T3) CFU 100g-1 on nutritional parameters of rainbow trout fry (0.538 ± 0.197 g body weight) were compared for 60 days, with each treatment carried in three replications. A significant difference was observed between treatments and the control in protein and lipid gain and also body composition (p<0.05). Despite a significant difference of metabolic growth rate in T1 and T2 with T3 and the control, no significant difference was observed between T3 and the control. The results demonstrated that the use of thesebacteria could improve nutritional parameters and metabolic growth rate of rainbow trout fry.

Abstract
Asparaginase and amylase are widely used enzymes in various industries, which can be produced by endophytic fungi. In this study, the ability of producing these two enzymes in endophytic fungi isolated from six species of Thymus has been reported for the first time in the world. Among 89 isolates of the test, 34 isolates produced asparaginase among which M24 (Fusarium subglutinans) displayed the greatest enzyme activity. Thirty three isolates showed the ability to produce amylase while the greatest enzyme activity belonged to M53 (Curvularia akaii). This study can be regarded as a preliminary work and endophytic fungi of high activity are proposed as possible resources for control of cancer in humans and for industrial applications.

Abstract
The novelty in typography coupled with narrative techniques has turned Bivatan (Tehran, 2008) into a quasi-metafiction, i.e. a story which explores the process of its own construction. While in Bivatan the author is supposedly trying to produce a metafictional effect, a closer investigation into the novel will prove this claim void. In fact, Amirkhani’s novel fails to step into the realm of postmodernism.

Abstract
Most patients with liver diseases are in the waiting list of liver implantation for a long period of time because of the lack of enough donors. Liver differentiation potential of Mesenchymal Stem Cells (MSCs) is a new perspective in curing these patients. Tissue engineering improves hepatocyte differentiation by coating the culture surfaces with Glycosaminoglycans (GAGs) such as Heparan Sulfate (HS). Cell detachment and death during hepatogenic differentiation hamper the efficiency of cell therapy. This study aims to establish a matrix. mimicking the liver extracellular matrix, which supports the attachment and proliferation potential of MSCs, as well. Collagen was physically coated on polystyrene plates. Collagen-GAG matrix was constructed by covalently immoblizing the HS molecules on collagen by EDC. Cell attachment and proliferation were evaluated by direct cell-counting and MTT methods. GAG presence on collagen was verified by Safranin O staining. Comparisons showed that the highest attachment belonged to collagen, collagen-HS and polystyrene, respectively. Collagen matrix showed also the highest cell proliferation. Collagen-GAG provided more suitable matrix for cell proliferation compared to polystyrene. The results further showed that biomimicked collagen-GAG matrix supports superior attachment and viability for MSCs compared to polystyrene.
