The statistical population of the research consists of managers, assistants and marketers of saffron processing centers and saffron sales centers of saffron business clusters in South Khorasan, whose number is 987 people. The sample population was equal to 278 people, and the necessary information was collected using a questionnaire. SPSS and AMOS software and structural equation analysis were used for data analysis. The inferential findings of the research showed the complete compliance of the measured factors with the existing theoretical models and the complete consistency between the theoretical constructs and the experimental constructs of the research. Accordingly, the educational role of promotion in the theoretical model was confirmed in ten dimensions and the social role of promotion in five dimensions in the final models. In the educational sector, the most important items affecting the development of saffron business clusters are "holding specialized seminars and familiarizing investors with the capacity of saffron", "establishing internal and external exhibitions to display saffron products" and "using virtual networks to advertise saffron products." " and in the social sector, the most important factors affecting the development of saffron business clusters are "creating culture about the place of saffron in the household food basket" and "investment risk for saffron product".

According to the theory of intertextuality, no context is independent of other ones; contexts are interrelated and bound to the contexts before and after them. This article aims to study the intertextual relations between the sonnets of Hafiz and Houshang Ebtehaj aka Sayeh. From among the Iranian contemporary sonneteers Sayeh is closer to classic poets and to Hafez in specific, regarding his fluency and stylistic composition. The question here is the intertextual frequency between Sayeh’s sonnets and Hafiz’s. Manuscript profile -

The quenching constants and binding parameters (binding constants and number of binding sites) were determined by fluorescence quenching method. The obtained results revealed the presence of a static type of quenching mechanism in the binding of GSH-AuNCs with BSA. Based on the thermodynamic parameters extracted from the fluorescence data, it was shown that binding of GSH-AuNCs to BSA was driven mainly by van der Waals and hydrogen bonding interactions. The displacement experiment shows that GSH-AuNCs can bind to the subdomain IIA (site I) of albumin. Manuscript profile -

Territorial development researchers believe that formation of regional industrial clusters improves competitiveness and plays a role in promoting competitive advantages and regional development. Hence, because of the possibility of realization of competitive advantage, industrial clusters became a focal point for research and policymaking. Against this background, the purpose of this research is to analyze and review the role of industrial clusters on the development of regional competitiveness and assumes that the higher number of relations in an industrial cluster leads to higher level of regional competitiveness. The research applies descriptive-analytical research method and utilizes questionnaire to collect data. The data was studied by SPSS and Lisrel software packs after approval of validity and reliability of data. Findings corroborate the relationship between the higher number of relations in industrial clusters with the higher level of regional competitiveness and also identifies the contributing factors to development and stimulation of regional development which is ranked by the order of their effect as follows: 1. Social relations, 2. Geographic and location relations, 3. Economic relations, and 4. Institutional relations. Manuscript profile -

Study sample size was 107 individuals randomly chosen from the population of these regions. The sample was calculated by using Cochran formula. Instruments included a questionnaire which its face validity was confirmed by a panel of experts and experienced instructors. The reliability of the four items of the questionnaire was 78.1%, 88.1%, 72.3% and 80.6%, respectively. Data from the completed questionnaires, using Win/SPSS version 21 of the Kolmogorov-Smirnov test statistics, descriptive and analytical statistics to assess the normality of the data, a Friedman test to rank the items in the single-sample t-test comparison was used to test the hypotheses and answer questions. Results showed that the variables associated with the cluster development agent, broker organizations and support institutions, business environment and development of clusters of clusters with the successful implementation of development programs is a positive and significant correlation. These variables can affect the success of the development of industrial clusters. These factors have also been linked to prioritize items. It was found that no matter how the scales will rise above and be evaluated from the perspective of people over the clusters will also increase the success rate of development. Manuscript profile -

Thererketing of fore, a strategic factors analysis approach was used to identify the strengths, weaknesses, opportunities and threats of the raisin market in the manufacturing and processing sector in the form of a marketing mix. The data needed was collected by conducting interviews with 10 experts of the Ministry of Commerce, Chamber of Commerce, Ministry of Agriculture and Exporters of Raisins. The specialized questionnaires were completed by managers and experts of the companies producing and exporting raisins in Qazvin and Tehran. According to the results of the internal factors matrix, in the mix of processing, product, physical evidence and position, strengths overcome weaknesses, and the results of the external factors matrix indicated that opportunities overcome threats. The results obtained from the matrix approach to status quo analysis suggested the diversity and competitiveness of marketing mix strategies. Thus, quality promotion of derivative products, the periodic use of areas of grape cultivation and raisin processing are recommended for maintenance and improvement of the soil, the emphasis on farm productivity and the development of conversion and complementary industries in the major areas of grape cultivation...

In terms of understanding the role of catalysis, these smallest bimetallic nanoparticles provide the simplest prototypes of Pd-Co bimetallic catalysts for different compositions. In this study, the effect of LixO (x=1,2) on PdCo nanoalloys has been investigated comprehensively employing the density functional theory (DFT) to identify the mechanism of structural, electronic, and energetic properties of the studied species. Binding energies are calculated for stability analysis which is very important for nanoparticles. Results show that lithium oxides are generally adsorbed by cobalt sites on the Pd-Co substrate. This is important for determining active sites of the catalytic material. Furthermore, the structures have low symmetric properties. Hence, this study might provide an initial structural evaluation step for future studies related to the possible new catalytic material of Li-air batteries. Manuscript profile -

With the exception of two villages in this city, the dialect of the rest of the people of the city, is Lori. The number of villages studied is 59 ones. The research method was a combination of field and descriptive methods and linguistic materials were collected by guided collection method. The questionnaire of this research is based on the national project of Atlas language, which includes 105 words and phrases and 36 sentences. Data were transliterated after the interview using the International Phonetic Alphabet. Some words of this dialect are completely different from standard Persian, some have only a different pronunciation and some are completely the same. There are five types of syllables in this dialect, which are: cv, cvc, cvcc, ccv, ccvc. Also, in this dialect, vowel extension causes semantic differentiation in some cases. The order of adjectives, and nouns is the same as in Persian, except the ones in some cases, [e] are omitted. The plural sign in this dialect is [-æl], added to the end of the nouns. The definite article is / -æku / and / -ku / added to the end of the definite nouns. Manuscript profile
