Abstract
From 2009 to 2012, 16 species of Curculionidae (Coleoptera) from the subfamily Lixinae were collected on 17 species of food plants in Iranian rangelands. Identified species belong to seven genera in the tribes Lixini and Cleonini. The host plants from which they were collected were in the families Asteraceae, Fabaceae, Apiaceae, Campanulaceae, Brassicaceae and Zygophyllaceae. Of the 16 species that we captured, two (Lixus subfarinosus Desbrochers, 1893 and Larinus remissus Faust, 1889) represent the first records from Iran. These new data also extend the known ranges of several species (Larinus fucatus Faust, 1894, Larinus grisescens Gyllenhal, 1835, Microlarinus rhinocylloides Hochhuth, 1847 and Bangasternus planifrons (Brulle, 1832) in Iran. The distribution of beetles and their associated host plants are presented and ecological notes on each species are provided.

Abstract
Background:
The innate immunity plays an important role in the host response to transplantation by Toll-like receptors and results in development of acute allograft rejection. The aim of this study was to evaluate the association of TLR2 and CD14 (co-receptor) gene polymorphisms with acute rejection in kidney transplant recipients.
Methods
: The study was conducted in a population of 239 subjects consisting of 71 patients with acute rejection, 71 patients without acute rejection (SGF) and 97 Healthy Control (HC). The allele and genotype frequencies of TLR2 (R753Q, rs5743708) and CD14 (-159 C>T, rs2569190) polymorphisms were genotyped by Real-time PCR in the study groups.
Results
: Genotype distribution of CD14 -159 polymorphism was significantly different in AR vs. SGF and HC. CD14 -159 TT genotype was more prevalent in rejection than SGF and HC (P<0.0001, P<0.007, respectively). Also Graft loss, defiened as need of dialysis after acute rejection, was occurred in 24 patients (33.8%) from AR group. The frequencies of three genotype in CD14 (TT, CT, CC) in rejection With Graft loss were 75.0%, 20.8% and 4.1% respectively, While 25.5%, 31.9% and 42.5% in rejection without Graft loss (P<0.0001 for TT vs. CT, CC). Many recipients with AR were involved with graft loss had CD14 -159 TT genotype, whereas only a few recipients without graft loss had TT genotype (p<0.0001).
Conclusion
: Therefore, due to the importance of CD14 polymorphism (-159 C/T, rs2569190) in disease progression and also as a biomarker, could be considered as a crucial therapeutic target in early prognosis of acute rejection

Abstract
Privatization of banking system in the Iran, emergence of new competitors and increased competition between public and private banks to retain customers and attract new ones, made banks to Customize their services. Banks do such as a policy to maintain and attract new customers. This happens in customer behavior assessment in terms of the dynamics of psychological (loyalty, trust and customer satisfaction) and are evaluated using ECSI model. In this regard, data collected through questionnaires distributed to available customers one of the Bank. Results showed that all the hypotheses of the study were accepted. If customization is performed in a appropriate manner, customer satisfaction, which is a prerequisite for loyalty, will improve. Customized services make customer encouraged to believe that bank was sensitive to his/her demands and as a result increase customer’s trust which lead to loyalty. Therefore, this study can help managers and policy makers who are executing in the bank.

Abstract
Research subject: In the present study, titanium dioxide/silver nanocomposites (TiO2/Ag) were synthesized by sol-gel method and their performance for photocatalytic removal of metribuzin was compared with commercial TiO2 catalysts P25 Degussa.
Research approach: The synthesized nanocomposites were evaluated using X-ray diffraction spectroscopy (XRD), field emission scanning electron microscopy (FESEM), and energy dispersive X-ray analysis (EDX). The effect of operating parameters including reaction time (0-240 minutes), pH (9-4), catalyst dose (0.005-0.015 g), temperature (10-60 ºC), visible light and UV light radiation, concentration Initial metribuzin (10-25 mg/L), the catalyst effect in the dark, and the amount of silver in TiO2/Ag nanocomposites (0.10-7% by weight) were investigated on the photocatalytic removal of metribuzin from artificial and real aqueous solutions.
Main results: Laboratory investigations showed that TiO2/Ag nanocomposite containing 10% by weight of silver, reaction time of 120 minutes, pH equal to 6, catalyst mass of 0.013 g, and initial concentration of 10 mg/L metribuzin are the best properties to maximize the removal of metribuzin in the presence of UV light. The obtained results showed that the synthesized TiO2/Ag nanocomposite has a higher potential in the degradation of herbicides compared to the commercial TiO2 nano-catalyst. In addition, the proposed method was used to remove metribuzin injected into the water of the Karun and Zohreh rivers and the wastewater of the sugarcane factory under optimal conditions, and successful results were obtained. Also, the results of using and regenerating the titanium dioxide/silver catalyst three times to remove metribuzin show the high efficiency of this photocatalyst in removing metribuzin from water samples. Comparing the methods available in the literature for the removal of metribuzin with the present method showed that the proposed method is better or comparable to the reported methods.

Chalcidoidea play an important role in the biological control of many agricultural pests. The present study determines and compares the diversities of this superfamily in four ecosystems in the Lake Urmia basin. It is the largest hypersaline lake in the world with a large basin of different ecological conditions in northwest Iran. These stations were: Khajeh (K) and Tasuj (T) in Lake Urmia Basin (LUBin) and Khoda-Afarin (KA) and Tikme-Dash (TD) out of their (LUBout). Four months of Malaise trapping in these habitats resulted in a total of 512 specimens from 11 families of Chalcidoidea, including 6, 9, 10 and 10 families in K, KA, T and TD, respectively. Maximum abundance was observed in the T station with 192 and the minimum was in the K station with 38. However, the families, Encyrtidae and Chalcididae have maximum abundance in T and KA, respectively. The maximum activity of chalcidoid wasps was observed during June-August. The majority of the species were belonging to the family Mymaridae (25%), in LUBout habitats peaked at 47 specimens in TD during the sampling period, while the corresponding LUBin habitats peaked at 40 specimens in T. The two LUBout habitats had greater community similarity (60%) than found between in and LUBout habitats (42%) and diversity of chalcidoid wasps in LUBout was found much more than LUBin. Biodiversity studies showed that the KA station has the greatest values of diversity, evenness, and richness of Chalcidoidea. This station is located outside of Lake Urmia basin with the warmest and most humid climate and forest ecosystem on the margins of the Aras River.

Abstract
Typology of language is 250year old. It is a systematic study of variations among languages and the presupposition of this definition is to consider some general principles governing language diversities (Comrie, 2001: quoted by Dabir-moghaddam). Word order is one of the integrated fields in determining differences and similarities in typology. Hawkins is one of the eminent linguists who has been the most influential figures of this branch specially word order. In addition to his vast knowledge in Generative Grammar, he had presented principles and universals related to word order (Hawkins, 1983:10). Dialectical studies have expanded greatly over the recent decades in Iran so that many linguists and typologists began to record and study the Iranian languages and dialects, they carried out many studies in the field of different dialects. The purpose of this study is to introduce Hawkins' theories, principles and universals related to word order, besides comparative analysis of word order between Azeri and standard Persian. This study was performed based on practical researches, theoretical framework and data collected through questionnaire in the analytic-descriptive method, also its conclusions prove the identity of Hawkins' some approaches on these two languages as well as verifying the similarities and differences about word order.

Abstract
In order to introduce new chemical weed management program in maize weed control in Iran, a study was conducted during 2014 and 2015. Experiment were carried out in a randomized complete block design with three replications. 15 treatments of the common maize herbicides, including nicosulfuron, foramsulforon, eradicane and 2,4-D + MCPA were applied in their recommended doses, moreover the treatments related to cycloxydim with dicamba + tritosulfuron were used with different doses and in different times along with two control treatments (weedy and weed-free). Treatments contained 75-150 g a.i. ha-1 of cycloxydim, showed similar results with the common treatments including nicosulfuron, foramsulforon, eradicane and 2,4-D + MCPA. However, treatments with high doses of cycloxydim, had a significant reduction in weed density and weed biomass. There were no significant differences between the effects of treatments on maize grain yield and biomass. Despite the acceptable weed control of the combined treatment of cycloxydim with dicamba plus tritosulfuron, maize canopy could overcome weed growth. Based on the results and by considering cycloxydim efficacy in controlling perennial grassy weeds in maize plantation, this chemical is a suitable option during different growing stages of weeds and maize. Finally, the application of 200-300 g a.i. ha-1 of cycloxydim combined with dicamba plus tritosulfuron was the best option from an economic and environmental safety points of view.

Abstract
Aims: Religious places are considered as important areas in cities so that they have supplied the bio balance and social life in the past. The development of cities and population growth have disrupted the balance of such textures and caused fundamental changes in their structure. An example of this issue is the inefficient texture of Emamzadeh Saleh (AS) which has been damaged in terms of historical values with the expansion of the city and its adjacent commercial space. Thus, regeneration of this urban area based on the recognition of contextual problems and the attitude of Islamic city studies and contemporization is among the objectives of the present study.
Instruments & Methods: This study is applied-developmental and its method is based on descriptive-analytical method. The library is the data collection tool for discussing the component of regeneration and the criteria are extracted through analyzing the data. In addition, the analysis of texture is performed through field surveys and observations.
Findings: By reviewing the previous studies, Islamic city strategies are explained based on environmental, physical, economic, and social criteria and the components of contemporization are extracted based on these criteria. Besides, the strengths and weaknesses of the adjacent urban area have explored for identifying the regeneration components.
Conclusion: Urban regeneration facing runaway development requires an identity-oriented and originality-based approach in order to restore the past social value based on society needs by the help of the latest factors. In Islamic city studies, the status of religious places is of great importance in quality improvement and its epitome is contemporization adjacent areas of Ememzadeh Saleh (AS).

Abstract
Aims: The forming elements result in the shape of the city during the history and according to the requirements of their dweller have followed a lawful and completely intangible geometry that, in their unorganized appearance, can interact and strike a balance among government, nation, and religion. The present study seeks to read and analyze the hidden geometry in the form of the city in the historical past that facilitates the connection between social pillars of the city.
Instruments & Methods: The method of this study is based on a qualitative approach of the historical-analytic type. By studying in the libraries and documents, this study has analyzed the hidden system of traditional city and the impact of modern development on it. In the case study of Sabze-Meydan, reading the hidden geometry is based on three heads of state, nation, and religion.
Findings: Hidden geometry in historic cities is a spirit that dominated the inner layers of the city and, with a systematic structure in functional and perceptual aspects, regulates the religious, political, and social relations of its inhabitants. With the advent of modernity and its fundamental transformations, the city of Tehran has been transformed. The proportions of the hidden and organic geometry in the Sabze-Meydan complex are transformed into euclidean geometry with perpendicular streets, and its balance is disturbed.
Conclusion: The geometric system contained in a city expresses the identity and civilization in it. The regular geometry of the modern city contrasts with the inner authenticity of the historical areas. Hence, the study of the hidden geometry of historical zones requires the adoption of an appropriate intervention approach in the city’s historical and charismatic tissues, through which historical authenticity can be restored.

Abstract
The relation between culture and language, features the need to examine the effectiveness of language textbooks. Considering the goal that foreign language teaching is mainly associated with the entry of cultural issues into the learner' knowledge, this need increases especially during learning a foreign language. Due to the today's growing importance of visual communication, this article offers a new perspective on images of English language textbooks in our system of education, based on the semiotic model of Kress and Van Leeuwen (2006), which emphasizes the importance of constituent elements of culture and society in analyzing linguistic signs; such as clothing, traditions or customs of cultures and subcultures. Paying attention to limitations of this case study, "ethnicity and location" are analyzed in the images of "Visions" and "Prospects". The present study explains how discourse is represented in these images, based on a scientific background and descriptive-analytical method with the aim of examining the social and cultural functions of language. The results show that the studied textbooks don't have a specific "ethnic-racial" approach and selection of "place" was without bias of the source language or the target language; In this way, the illustrator didn't pay special attention to his or her own language in choosing the images
1. Introduction
Due to the today's increasing importance of visual communication, the present study has a new perspective to this issue and examines the various forms of visual communication and discourse representation in images of "Visions" and "Prospects"related to place and ethnicity. Sometimes it is not possible to express everything that is presented through the images with a linguistic tool, and the opposite is also true. In this study, in addition to examining the semiotic pattern of Kress and Van Leeuwen (2006), we will look at the questions: how discourse is represented in images related to "ethnicity" as well as "place". A deep connection between English language and its related culture and the need to confirm that English language textbooks contain cultural issues in addition to linguistic issues, resulted the researcher into analyze multi-style texts after extracting. In this article, we try to analyze images at the levels of representational, interactive and compositional meaning using descriptive-analytical method. This study is based on the hypothesis that the mentioned English language textbooks, don't have a specific ethnic-racial approach and images related to "place" play a role in conveying concepts without biasing the source language or the target language.
2. Literature Review
It is necessary for images to meet the conditions of representation and communication, sothat they act as a complete communication system. One of the language semiotics' schools is social semiotics, which deals with a social dimension of meaning in the communication media and pictures. Social semiotics has many possibilities for semiotics and is presented with the assumption that signs and messages should considered in the field of social processes (Kress & Van leeuwen, 2006: 6). Studies like Meshkat (2002), Shin & Kubota (2008), Amouzade et al (2013), Wue (2014) and Ahangar & Shirvani (2016) have discussed the discourse representation in multimedia texts. However, the present research is a new study to newly published English textbooks "Prospect" and "Visions". Although Halliday's theory (1994) is capable of analyzing pragmatic aspects of language, it is incapable of studying multi-style texts. Kress and Van Leeuwen (2006) improved and generalized his idea to images. Torres (2015) evaluated textbook's social-visual semiotics in the educational system of South Korea based on Kress and Van Leeuwen (2006). His findings indicated that some visual and verbal messages conflict with each other. He also explains that this opposition reveals the purposeful ideology within those images. Rouhani and Saeed Far (2013) worked on a comprehensive study using the grammar model of Kress and Van Leeuwen (2006). They analyzed the images of old high school textbooks. According to their research, images aren't used in the service of language learning completely. With this in mind, let's know the other part of paper.
3. Methodology
This research applies Halliday's theory (1994) and Kress, G. & Van leeuwen (2006) to analyze discourse representation in images of English textbooks "Prospects" and "Visions" which affect the students as learners. In this article, we try to analyze images at the levels of representational, interactive and compositional meaning using descriptive-analytical method.
4. Results and Discussions
By analyzing the data, the initial hypotheses are confirmed. In this way, the studied images show that people having different ethnicity are the same. They tend to show that it doesn't matter what their particular race or skin color is; rather, human beings regardless of these features, can be successful and efficient people if they have necessary competencies. In selecting place-related images, public locations such as the street and the classroom are selected. It has a general aspect and isn't specifically related to a particular language or culture; As a result, no orientation of the source language or the target language plays a role in conveying concepts

Abstract
Aims: The heritage of early modern architecture in the first Pahlavi era, represents the concept of identity in a new domain which could be attributed to discontinuity of traditional Iranian architecture. Historical architecture in the first Pahlavi era is one of the first attempts made to protract the identity of Iranian architecture in its new shape. The present study was an attempt to retrieve the roots and levels of the historical approach in the first Pahlavi era to explain how identity remains embedded in the modern architectural heritage of this era.
Methods: in the present qualitative study, a descriptive-analytical approach is used to decipher the relationship between the cultural values of modern architectural heritage and the concept of identity in architecture. Using relevant documents, the researcher has tried to explore the trend of architecture formation in the Pahlavi era. By studying library sources, the researcher has also tried to analyze the concept of identity in architecture as well as components affiliated with that. In the next step, an inferential approach is used to investigate the relationship between historicism and identity development in the modern architecture heritage and the results are used to analyze a series of selected buildings associated with the historicism current of the first Pahlavi era.
Findings: Imitative, schematic and conceptual historicism are three components of retrospective approach that are directly correlated with different levels of identity: formal, inferential and semantic.
Conclusion: In the architectural heritage of the first Pahlavi era, Identity is, from a historical perspective, formally transferred through a direct perception and objective adaptation to the attributes of historical architecture in Iran. In the wake of that, another group of buildings was formed, which transferred identity through content representation and as a result of indirect use of Iranian architectural elements and the refinement and abstraction of historical components. Despite emphasizing on similarities, these buildings actually depict a cultural distinction in architectural heritage of this era.

Abstract
Numerical simulation of turbulent flow and heat transfer in film cooling from a cylindrical hole in three-dimensional case is considered. For this purpose, turbulent heat flux term of energy equation is usually modeled by simple eddy diffusivity model with constant turbulent Prandtl number, while experimental and numerical researches show that the prescribed constant value of turbulent Prandtl number is far from reality. In the present study, second moment closure (SMC) models with wall-reflection term is applied for modeling the turbulent flow and heat transfer in film cooling flow. Comparison between the numerical and experimental results show that the explicit algebraic second moment closure models have more ability to better prediction of temperature field in film cooling. In addition, turbulent Prandtl number distribution for film cooling has been investigated. The range of this parameter for the desired geometry has been identified from 0.1 to 0.95 in the near of injection hole to far from it respectively. Finally, in order to enhance the capability of simple eddy diffusivity model in simulating film cooling heat transfer, the value of 0.7 has been proposed for turbulent Prandtl number instead of the common value of 0.85.
