Abstract This article investigates the use of wing and angel in Pre - Islamic period artists. The investigated various visual model remaning of winged animals, espically winged man show that angel carnated is not exclusively winged man and is not just an Iranian symbol. In a way, wing in a Pre - Islamic period have often been the power and eazata sing and symbol. It is strongly gussed that the origin of the symbols of angel and wing have been belonged to Mesopotamaia. The wingins in the beginnig (i.e., the third millennium BC), based on the oldest model of Winged man has been belonged to the Ald Period. But the Three - winged man was the specific symbole of Achaemedis.

MaqamateHamidi is a good example of a text, which has emerged out of the previous culture and literature. This book has turned into a broad site in which various texts have been mixed in such a way that it represents an extensive array of genres. The main purpose of this study is the discovery and analysis of the intertexual relations in Maqamate Hamidi. To achieve this aim, we investigated twenty three Maqams in this this book in the light of Gerard Jeant’s Transtexuality Theory. The results indicated that MaqamateHamidi is a good example of intertexuality in a sense that different allusions to the Holy Quran are made, and also Arabaic poetry is extravagantly is used. Moreover, Hamidi’s book is greatly modeled on Hamadani and Harriri’s works, which attest to the intertextual nature and diversity of voices within this book. This intertexuality reinforces the coherence of meaning in this text, which is in line with Gerard Jeant’s Intertexuality Theory.

Formalin is a common disinfectant and therapeutic agent in fisheries-related activities. Considering large variation in susceptibility of different species to formalin toxicity, it is necessary to determine its toxicity and safety margins in different species, separately. Therefore, to investigate formalin acute toxicity and safety margins on Caspian roach, an experiment was conducted in 1g Caspian roachs Rutilus rutilus caspicus. Fish were exposed to 0, 30, 40, 45, 50, 55, 60, 70, 100, 150, 200, 250, 300 and 400 ppm formalin and mortality was recorded after 0.5, 1, 12, 24, 48, 72 and 96h. 0.5-96 h LC50 values were 49-246 ppm. The lowest observed effect concentrations (LOEC) were found to be 40-150 ppm at different periods. No observed effect concentrations (NOEC) were 30-100 ppm at different periods. According to regression model for NOEC versus time, concentrations of 88.4, 80.3, 51.2 and 40.1 ppm are suggested as the maximum concentrations for 0.5, 1, 12 and 24 h bath treatment, respectively. Results showed the recommendations for formalin safety in the literatures are not applicable and valid for Caspian roach. Such differences could be due to species or experimental differences which should be taken into account before treating.

Aims: Urban spatial planning may be defined as the spatial planning in the geographical location of the city, based on the approach of providing the needs of inhabitants within the geographic spaces, following the recreation of the roles and functions of urban elements. By planning identity signs in urban spaces, it is meant to make the safety and security of the city sustainable. By identifying the emotional, psychological, and educational needs of citizens, visual discipline is created; by planning the identity signs of city’s index and planning the signs, vitality is created for citizens; and in completion, with city architecture, facade and urban landscape will be managed in such a way that the citizens' mental and objective needs are met. Given the role of signs in the city, the question of this study is in what situations, will signs meet the need for security and self-awareness of the inhabitants? In what situations, are vitality and beauty transmitted to the citizens and affect the city's atmosphere? Applying a descriptive-analytical method and using library studies as well as available documents, this study examined the planning of urban signs to achieve the main function of the sign.
Conclusion: Signs in urban spaces with appropriate planning can have positive effects and meet citizens' needs for self-awareness, security, education, etc. In this regard, convergence should be created among decision makers, urban managers, and culture, community, economics, politics, and geography of the urban space of citizens.

Smart materials and shells affect on represent the space and identity of a society with their special activity and like any technology and element, it has its own effects and consequences and it can be said that based on the visual attractions and philosophy of the age of communication and visualization the culture of societies founded. The aim of this research is explaination of these effects on urban smart surfaces from psychological and intellectual and cultural anomalies aspects and helping designers to use it logically and in accordance with the culture and smart buildings of the community. The present research has a positive-content aspect and from another aspect, has a normative-content structure. Also, the research method includes descriptive and analytical research along with qualitative strategy, because it addresses contemporary social and cultural conditions. Data collection is based on library studies and documentation. The physical and material effects of smart shells that make urban facades based on perceptual visual cultures in perceptual aspects are criticized: truth and reality, time and space, experience and event, equality and justice, knowledge and information in a society and consider equal the meaning of firmness with persistence, generosity with lavishness, tolerance with indifference, adherence to affection and beauty with pretense and and in sensual aspects: Unity, distance and distance from the world, distorting other senses, undermining the message and meaning of the sender of the message, separation, isolation, apparent attachment, limiting taste, inhumanity of architecture and urbanization would be the results of increasing use of them.

The Economic Cooperation Organization (ECO) is the result of the political will of its three founding countries for economic convergence, which had previously symbolized in its predecessor, the Regional Cooperation for Development (RCD). The desire of Iran and two other neighbouring countries to fill the void of past regional cooperation led to the revival of RCD in ECO in 1984. The collapse of the Soviet :union: and the independence of the Muslim Republics led to expansion of the organization. During 1992-96, ECO realized the main areas and priorities of cooperation and established several regional institutions and since 2006 entered the implementation phase of its agreements and strategies. This research seeks to analyse the activities of ECO to achieve the set objectives and evaluate the degree of their realization.. The main question of the essay is whether ECO has been able to realize the goals of regional integration? What has been the role and influence of Iran in the successes and failures of ECO? And can we still hope for the success of this organization? The research hypothesis is that ECO has not achieved much success in the implementation of a large number of agreements and regional plans, and its activities have not had a tangible impact on regional development and prosperity. In the meantime, Iran has played a large role in the failure of ECO. The research method is descriptive-analytical, and the data has been collected and analysed by referring to ECO documents, library sources and field experiences.

Acute toxicity (96h-LC₅₀) of potassium permanganate (PM) was determined for Caspian kutum Rutilus frisii kutum at two size classes (1 and 3 g). Static renewal method was used. Fish were exposed to different concentrations of PM and mortality was recorded thereafter, until 96 h. Exposed fish showed behavioral stress indicators. 96h-LC₅₀ was calculated to be 3.204 (3.147-3.260) mg/L for small fish and 3.460 (3.393-3.528) mg/L for large fish. Safe concentration for small and large fish was calculated to be 0.003-0.320 and 0.003-0.342 mg/L, respectively. No Observed Effect Concentration (NOEC) and Lowest Observed Effect Concentration (LOEC) were 2.6 and 2.8 mg/L for small and 2.8 and 3.0 mg/L for large fish. Results indicated that Caspian kutum is susceptible to PM toxicity; although less than many tested species. Likewise, toxicity of PM significantly decreases with increase in fish weight. Higher tolerance in large fish compared to small fish might be as a result of increased stress resistance and higher quality of these fish.

In spite of their apparent diversity and variety, Arabic and Persian maqamas are unified, which is the result of a common narrative structure. The main purpose of this study is to uncover this common structure. To this end, 124 maqamas including those of Hamadani, Hariri and Hamidi were analyzed based on Vladimir Propp’s morphology theory. The results indicated that Arabic and Persian maqamas are similar to each other in terms of character types and functioning. Moreover, in 31 functions and seven areas, they are in line with Propp’s theory. Such an approach allowed us to investigate all of these 124 maqamas within a single model and to conclude that narrative structure of these maqamas is the result of a single and primary plan, which has been effective in creation of this genre.

  Background: The over-expression of recombinant proteins in large amount is important for production of therapeutic proteins and structural study. There are several systems for expression of recombinant proteins. One of the most relevant expression systems is Escherichia coli (E. coli). Although this organism has many advantages, most of recombinant proteins expressed in E. coli hosts form inclusion bodies. For gaining biological activities, these structures should be refolded. Many techniques have been developed for in vitro protein refolding.   Methods: In this study, a method was designed for inclusion body solubilization and protein refolding. IBs were solubilized in the solution containing 2M urea. This is a mild solubilization method without creating random coil structures in the protein. Results : Inclusion bodies undergo mild solubilization with maintain native-like secondary structures. Solubilized proteins were refolded on chromatography column by using native buffer conditions. The results showed the recombinant proteins were purified with high efficiency without aggregation. Conclusions : The results suggest that this method is easy, efficient, cheap procedure and usable for obtaining refolded recombinant proteins. In addition, purified protein with the method can be used in diagnosis and/or treatment of diseases.

Occupation of Palestine and Iraq’s invasion to Iran, as two enormous events of the twentieth century, overshadowed the lives of two lands. Meanwhile, literature- especially poetry-as one of the thinking areas of the Palestinians and Iranians, had witnessed a fundamental transformation. The poets of the two lands parallel to the enemy’s attack, showed resistance together with the combatants against the invasion of the enemy. “Smyh Alqasm” and “Hassan Hussein were two poems who left various worthwhile resistance poems. One indicator of this type of literature is the use of dramatic, symbolic and lyric contents. The present paper intends to investigate the reflection of changes caused by the onslaught of foreign enemies on the deployment of concepts and symbolic myths as well as the homology, differences, semantic developments and concept changes of these themes in the lyrics of Samyh Alqasem and Hassan Hosseini. The results indicated that both Samyh Alqasem and Hassan Hosseini have used symbolic and natural, human being, animal and place lyrics but symbolic and lyric meanings in the poets of Samyh enjoy more initiative, variety and extension.

Background: Masske is a traditional Iranian butter made from yoghurt. The first aim of this study was to isolate and identify the nonlactic pathogenic microflora by culture and molecular methods of identification, and the second purpose was to identify genetic similarity of the isolated bacteria in Masske.
Materials and Methods: In order to detect pathogenic dominant indicator microorganisms, a number of 150 bacterial isolates from three Masske samples, which may comprise the repetitive isolates and could grow on appropriate media for Staphylococci and E.coli, were classified into 8 groups according to their phenotypic characterization followed by chemical tests. Then 2approximately similar isolates from each group were chosen (total 18 isolates; we selected 3 isolates from 2 groups of eight), and the sequencing of 16S rRNA gene was done for subsequent analysis.
Results: Among 18 bacterial isolates, Staphylococcus hominis was the most frequently isolated species during the manufacture of Masske as the presence of this bacterium was confirmed in 14 out of 18 samples. Also, the presence of Staphylococcus epidermidis and Escherichia coli was identical across the samples (for each one, 2 out of 18).
Conclusion: Our results based on cultural and molecular methods suggest making some improvements to the hygiene of Masske manufacture due to the high population of minor pathogens.

The 21th century has been confronted with wonderful changes in the dimensions of technology, social, economic, and political, perhaps no organization and settlement be safe from their changes and events. In recent decades, strategic management is one of the important organizational and institutional issues that has attracted researchers and experts. In addition, this strategic management has expressed among many new theories and approaches in developed countries and, consequently in all over the world including Iran, which in turn created a lot of new theoretical and practical challenges. This research has been tried by using a descriptive method, discourse analysis, and critique of the framework, that propose strategic management as new management in the service description of spatial planning. Therefore, in the first step, examined the constituent parts of the management spatial planning in the description of the services and then described planning and strategic management and strategic management process as the integrated and practical and at the end, presented suggestions for achieving strategic management in the description of the services of spatial planning with the achieve of integrated management, in the service description of the spatial planning, we will see the operational of the spatial planning oriented programs in the territory of Iran.

Literature of resistance has both human and world face. Efforts by a generation of fighters for liberation of land, religion, culture and traditions from the shackles of aggressors to national privacy and human values are done, which everyone can draw poetic and literary expression. Events such as occupied Palestine and Iraq’s attack on Iran caused the creation of unique works of the resistance literature of nations. Works of the poet of Palestinian resistance, “Smyah Alqasem”, poets of Iranian’s Sacred Defense, “Hosseini Hassan” and “Kaiser Amin Pour” are valuable legacy in the realm of the resistance poetry of the two territories. The present study is to investigate homology and differences in the poetry of resistance by relying on the works of two poets of the country. Research findings showed that sense of belonging to the land, disposal of foreign invasion and occupation are among the main factors in the incidence of resistance elements of Samyh, Husseini and Aminpour poetry. Land, war victims, rebellion against the aggressor, religious and ethnic motivations of struggle, martyrdom, the enemy, oriented ideals and values to override objections by flow resistance are the main themes of the poets.

In his Notebooks (1914-1916), Wittgenstein announces that ‘artwork is the object seen sub specie aeternitatis’. At nearly the same time, in another part of the world, there was a critic and thinker, who thought art as making objects ‘unfamiliar’. He was Victor Shklovsky. I argue that there is a noticeable and yet unintended similarity and relation between these two aesthetic viewpoints. Wittgenstein and Shklovsky’s emphasis on art is its power to pave the way for the readers (in the extended sense of meaning) to feel things in themselves and ‘out of their normal context’. As Shklovsky claims ‘art removes objects from the automatism of perception in several ways’; in contrast, through ordinary way of seeing, objects are ‘reckoned as nothing’. According to Wittgenstein and similar to Shklovsky’s attitude ‘aesthetically the miracle is that the world exists. That what exists does exist’. In this paper I attempt to show that the early Wittgenstein’s ideas of aesthetics are in harmony with the Shklovsky’s formalistic theory of art. In this direction, I focus on Wittgenstein’s sub specie aeternitatis’ and Shklovsky’s defamiliarization; because I think that they fill each other’s gaps. An artist defamiliarizes objects and the spectators see the objects sub specie aeternitatis. In Shklovsky’s thinking Habitualization (which ‘devours works, clothes, furniture, one’s wife and the fear of war’) is very near to what Wittgenstein means by ‘the usual way of looking at things’.

Today, sports are an essential part of the diplomatic tools of countries. As a desirable tool, the sport can shape the preferences of others through soft power. Therefore, the researcher decided to identify the political functions of public diplomacy and soft power in sports and tourism in Iran. This research was conducted in the framework of a qualitative approach, and data were collected through semi-structured interviews. The statistical population of the study was experts in the field of politics, sports and tourism, including five sports faculty members, five tourism faculty members, seven political science faculty members, and five people with executive work experience in the tourism and cultural heritage organization, and athletes with a history of participating in international competitions. The data collection method was a previous research study and an in-depth and open interview. In order to measure the reliability of the research, an intra-subject agreement was used. The average level of intra-subject agreement was reported as 89%. Based on the findings of the semi-structured interview, the most important political functions of public diplomacy and soft power in Iran's sports and tourism were six components: political character, foreign policy, domestic policy, political awareness, combating isolation, information and communication. According to the results of the research, it is suggested to use the advantage of sports, which is a common language between nations, to increase international communication and political awareness of sports ambassadors because of the benefits of the negotiations of athletes and coaches in sports events compared to official politicians; Diplomacy and communication are spontaneous and will face fewer restrictions.

Semiology and study of meaning and its effects on users is one of the new approaches that recently have become very popular in urban studies. It can be used as a useful and efficient tool for producing qualitative data out of the city and daily life of citizens and assist urban designers in identifying signs and concepts they represent. In this paper, Nazi Abad Neighborhood in Tehran is explored as a case study in terms of existence of signs, the effects of environmental meanings on different groups of residents and environmental legibility. The objective of this research is to review Lynch’s cognitive mapping approach critically and to study the effects of meanings embedded in urban elements and signs on creation of people’s environmental cognitive maps and legible environments. This is conducted by using surveys, cognitive maps, fieldwork interviews and photo-analysis method in the neighborhood. The findings, parallel to some other critics of Lynch’s studies, confirm that his five elements are mostly used for faster environmental perception and legibility, not clarity, and operate as functional features and cognitive maps vary depending on age, gender and socio-cultural characteristics of urban dwellers. People, based on their experience, culture, past history, ideology etc. perceive different meanings of the environment and can have specific interpretation of their neighborhoods according to their reading of environmental signs. Analyzing Cognitive maps of Naziabad residents and other aspects such as meaningful elements, symbolic buildings, memories and daily experiences revealed that these features, besides affecting cognitive maps, can work as a language via which residents can connect themselves to their environment. This confirms Peponis ideas who believed that there is a difference between people’s perception of and urban form based on their experience, memory, culture and everyday meanings and its verbal description. He believes that people usually use significant visual elements of an environment and not their reading or personal meaningful elements for way-finding or giving address to others. Therefore, urban designers can make environmental design and transformations with regards to elements that are meaningful in private and public life of people and provide an opportunity to create place attachment.

Supply chain Integration importance leads to this believe that some scholars express that the whole concept of supply chain management is derived from integration. Providing the basis for creation and effective continuation of supply chain management requires the recognition of main factors affecting the integration. Studies reveal that the organizations with higher levels of social capital are more successful than their rivals. So, the purpose of this study is to surveying Social Capital Influence on Supply Chain Integration. Considering the purpose, this study is applied research, and based on its research methodology, it is a correlation descriptive, and it is specifically based on the structural equation models. The population consisted of 435 organizations in food industry of Fars province in Iran, and via employing stratified sampling, 124 executives related to supply chain management were selected and the questionnaires were distributed and collected data were analyzed. This model suggests that five factors influence Supply Chain Integration, and the purpose of the research was to investigate the influence of social capital on these factors. The results indicated that the social capital has positive and direct relation with integration, communication pattern, trust and commitment and has no direct relation with power and attitude.
