Abstract: 

To investigate the effect of vermicompost, N fertilizer and their integration on growth, biological and essential yields oil and its components in two populations (Varamin and Isfahan), an experiment was conducted in a randomized complete block design with three replications in the field of Isfahan Medicinal Plants Research Center in 2016. Fertilizer treatments including 100% urea, vermicompost 33.3 and urea 66.6%, vermicompost 66.6 and urea 33.3%, 100% vermicompost and control treatment (without fertilizer) as the first factor and Varamin and Isfahan populations as the second factor were selected. The results showed that the interaction effects of nitrogen fertilizer and populations on all studied traits were significant. In both populations, nitrogen fertilizer improved height, biological and essential oil yields, content of essential oil compounds (d-Carvone and its yield, α-phellandrene and linalool; except p-Cymene and Limonene in Isfahan population). Since in medicinal plants, the quantity (biological yield) and quality (essential oil and d-Carvone; the most important ingredient and the highest amount of essential oil in this experiment), 66.6% vermicompost + 33.3% urea in Varamin population, was the best treatment in the experiment. In addition an in the direction of human health and sustainable agriculture, it is possible to reduce 33% of chemical fertilizers application and pollution; however, in terms of other essential oil contents (α-phellandrene, Linalool and p-Cymene), 100% vermicompost fertilizer treatment was superior in Isfahan population.

Abstract: 

Different TYPES of contact, including contact between node pairs, any-contact of nodes, and contacts of the entire network, are used to characterize social relations in mobile social networks. Different modes of routing, from the point of view of message delivery semantics, encompass unicasting, multicasting, any-casting, and broadcasting. Studies have shown that using probability distribution functions of contact data, which is mainly assumed to be homogeneous for nodes, improves the performance of these networks. However, there exists an important challenge in studies on distributions. A lot of works apply the distribution of one type of contact to other TYPES. Hence in routing applications, it causes to use of the distribution of one type of contact for any mode of routing. This study provides a complete solution to model each type of homogeneous contact data distribution and to use them in different modes of routing. We propose a routing algorithm that uses this new model. Results show that our solution improves the average latency of comparing methods Epidemic, TCCB, and DR about 3.5-times, 30%, and 45%, respectively. It achieves a delivery rate of about 5% and 6%, and average latency about 6% and 8% better than that of DR and TCCB, respectively.

Abstract: 

This study was conducted with the purpose of addressing the production of scientific works in the field of PRIVATIZATION of higher education abroad and the acquisition of discussions and components focused by studies, the results of the studies and the descriptive and formal analysis of the studies. Accordingly all works produced within the period of 2000-2015 in the Faculty of Education and Psychology database of Shahid Beheshti University were studied. The works were extracted from 33 journals in the field of higher education, including 24 scientific documents including 18 articles, 5 books and a thesis in the field of private higher education and analyzed by descriptive - analytic method. The findings are presented in three parts, the first part, related to the issues and factors considered by the study results showed that topics including the reason of PRIVATIZATION of higher education, goals, advantages and disadvantages and different TYPES of private higher education institutions have been more focused by the researchers. In the second part the results indicated that indiscriminate expansion of the private sector in higher education has led to lower quality, rising unemployment, failure to reduce financial dependence on public sector budgets, lack of responsiveness to labor market needs and priorities of individual interests to the social interests. In the third part the result of formal and descriptive analysis of the studies showed that 58.3% of the studies have been conducted within the years of 2011-2015 and 83% of the studies have used qualitative research and library method and only 17% have used the quantitative method and interviews and questionnaires. In terms of national and transnational studies 71% of the studies were national and 29% of the studies were transnational. In terms of cooperation and partnerships the group research was 8% higher than the individual research.

Abstract: 

The present study aims to explain the effects of tourism on the development of rural businesses in the city of Hamadan. This research is applied according to its purpose and based on its nature and method, it is of survey type and descriptive and non-experimental research and the method of collecting field and library information. The statistical population of the research based on the bachelor's standard is equal to 40 experts and the level of village analysis is equal to 40 villages in 9 villages. For validity of content validity method and reliability of research is Cronbach's alpha method that all questionnaires with a high rate of 0.7 have high reliability. In this study, variables fall into two categories of independent variables: including; Variables and factors of tourism and non-tourism affecting rural and tourism businesses and dependent variables that meet 4 criteria: 1. Physical-environmental criteria; 2. Management criteria; 3. Socio-cultural criteria; 4- Economic criteria are divided. In this research, two-sample test and one-sample t-test, correlation test to measure the correlation between variables, to measure the effects of tourism factors on businesses from univariate and multivariate linear regression analysis. And Chi-square test, Spearman test was used. According to the research results, tourism criteria with an average of 4.71 has the greatest impact on the development of rural tourism businesses and in fact is the only dimension that has significant effects on business development. Other non-tourism dimensions have relative and moderate upward effects. In fact, according to the classification that was done at the beginning of the study, tourism criteria have much more important effects than non-tourism factors. In conclusion, it should be noted that apparently the effects of different factors on businesses are not very high and are at a medium to high level. Among these, only tourism factors have high impacts, which is closely related to tourism factors and rural businesses. In fact, the set of tourism elements has a more semantic connection with businesses.

Abstract: 

In some point of view, neither Michel Foucault nor Ibn Khaldun are considered philosophers in the conventional classifications, but both are very  important in intellectual and, of course, in philosophical contexts, especially for those who are interested in the deep study of human life from the perspective of political thought.The main concern of two thinkers, one in the 14th century, the other in the 20th century, is the issue  of power, although neither of them provided a precise definition of it. In this article, an attempt has been made to show the place of power and domination in the political thought of both thinkers by examining the thoughts of two thinkers. And in search of an answer to this question, how did Asabiyyah and industry of religion in Ibn Khaldun's thought and social control through self-technology and discipline in Foucault's thought lead to the expansion of the domination of power? This article is written by analytically comparing the opinions of two thinkers based on Ibn Khaldun's most important book called Muqaddimah and Foucault's late works

Abstract: 

Many tubular joints commonly found in offshore jacket structures are multi-planar. Investigating the effect of loaded out-of-plane braces on the values of the stress concentration factor (SCF) in offshore tubular joints has been the objective of numerous research works. However, due to the diversity of joint TYPES and loading conditions, several quite important cases still exist that have not been studied thoroughly. Among them are internally ring-stiffened multi-planar XT-joints subjected to axial loading. In the present research, data extracted from the stress analysis of 81 finite element (FE) models, verified using experimental test results, was used to study the effects of geometrical parameters on the chord-side SCFs in multi-planar tubular XT-joints reinforced with internal ring stiffeners subjected to two TYPES of axial loading. Parametric FE study was followed by a set of the nonlinear regression analyses to develop four new SCF parametric equations for the fatigue analysis and design of axially loaded multi-planar XT-joints reinforced with internal ring stiffeners.

Abstract: 

Changing the ownership of the firms from governmental to other forms, along with the emphasis on cooperative ownership and increasing the share of this sector to 25% in Iran's economy, is one of the main aims of the comprehensive policies of Principle 44 of the Constitution of Islamic Republic of Iran. Therefore if such a change is supposedly true, to prove the preference of the change to cooperative sector as a sector through which the Islamic economics could be spread in the society, it should be shown that the firms operating under this kind of ownership had a better or at least equivalent performance as compared to the private or government sectors.And if no noticeable distinction in the performance of the economic firms is observed from this aspect, the emphasis on the ownership change, at least from an economic view would not be supportable.This paper strives to examine the distinctions in performance of the Manufacturing industries of the cooperative sector with the two government and Private sectors. Using plant-level data, labor productivity, and value added per unit of paid wages and salaries, employment generated, and finally the speedy growth of the employees of the manufacturing units during the Second and Third Development Plans towards segregation of ownership, are the analytical basis of This study. The results of this study show that changing to cooperative sin place of PRIVATIZATION is only possible through [handsome] productivity in the cooperative sector in comparison with the private sector, and consequently through the achievement of a level of profits equal to that of the private sector.
