This study was conducted during summer and winter of 2018- 2019 in the agricultural research field of Shahid Chamran University. Experimental design was split- plot based on RCBD with three replications. The main plot was the type of agricultural system in three levels including conventional (Conv), organic (Org) and sustainable (Sust) (integrated between Conv and Org) and sup- plot was the type of pre- cultivated crop in sequence with wheat including cultivation of mung bean (M- W), corn (C- W), sesame (S- W) and fallow (F- W). Yield quantity (yield and its component) and quality (grain protein), an estimate of photosynthesis matter transfer index of wheat and soil organic carbon (SOC) after one double-cropping were measured. The result showed that the highest (545.04 g/m2) and the lowest (409.28 g/m2) seed yields were obtained in Conv and Org respectively. In contract, with the changing type of system from Conv to Org, grain protein was increased significantly (from 8.3 to 9.6 %). In addition, the highest (535.47 g/m2) yield of wheat was obtained from M- W double cropping. On the other hands the highest remobilization and current photosynthesis matter were obtained in the organic agricultural system with M- W and conventional with M- W double cropping. The situation of SOC showed that the highest (33.18 mg/g) SOC was obtained in the organic agricultural system with C- W double cropping. The reason for improving SOC in the organic and sustainable agricultural system was application of organic matter (compost and vermicompost) and crop residue management. Totally, from the crop ecology point of view, sustainable agricultural method with a sequence of M- W was the most desirable system.

The importance of sustainability development for developing countries and their tourism is a major issue. This study presents a new approach and framework for spatial modelling of tourism products potentials (TPP) in their sustainability evaluation. The approach was developed based on the GIS multi-criteria decision analysis (MCDA) and its performance was evaluated for spatial TPP mapping in Tabriz city, Iran. To achieve this purpose, we recognized the main Components of Tourism Development indicators (CTDI) such as attractions, accommodation, services and infrastructures facilities to improving sustainable tourism, and determined their significance using the Geographic information SYSTEMS (GIS). Furthermore, the uncertainty analyze was applied to diminish the inherent error in criteria weights. A GIS-based aggregation function was applied to discern the TPP map. Finally, the emphasis in this paper investigates the practical usage of GIS for the benefit of sustainable tourism development. In particular, it inquired the possible opportunities and challenges facing the adoption of GIS to assist sustainable tourism development. The purpose of this article is to map and explore existing and potential attractions, tourism services and facilities in Tabriz and to ensure that potential opportunities are available for all tourists to enjoy enjoyable experiences in order to reveal their diverse economic, social, political and cultural benefits. Build on the positive and negative aspects of their construction and present them with appropriate solutions for tourism development that lead to sustainable tourism development and infrastructure improvement.

Air conditioning SYSTEMS are used in industries and residential environments with the aim of improving environmental conditions and creating a comfortable temperature for users. Considering the production of sound and vibration in most of its components, the lack of control of the production sound level always exposes the users to unwanted sound, which in addition to hearing complications, also causes fatigue and dissatisfaction with the environmental conditions. . Compressors are one of the most important sources of sound production in air conditioning SYSTEMS, and screw compressors are one of the most widely used in air conditioning industries. Therefore, the compressor shell should be designed to minimize the transmission of sound from inside to outside. Since the maximum working temperature of compressors is up to 80 degrees Celsius, therefore, in this research, an acoustic test was performed on a sample of a screw compressor shell in two modes of ambient temperature and maximum working temperature inside the acoustic room, and the effect of temperature increase on the sound pressure level. transferred from the shell to the external environment is discussed. Finally, based on the frequency analysis performed in two conditions of ambient temperature and maximum working temperature and comparing the amount of sound transmitted to the environment at different frequencies, practical solutions to reduce the amount of transmitted sound pressure have been presented.

The city's regeneration is one of the strategies that lead to urban deterioration and inefficient textures towards revitalization. Using SYSTEMS thinking on the subject of reinvention can lead to the identification of complex SYSTEMS that are considered effective in producing and reproducing worn-out textures. In this regard, this study was to benefit from a systemic approach in identifying the the roots of the production and reproduction of historical/worn-out textures in Semnan city. The leading research is among the applied research, and in terms of information and data analysis, it uses the descriptive-analytical method. The tool for collecting information is also in documents and surveys. The statistical population of the research was 18 university professors, experts, and officials familiar with the urban fabric of Semnan, who were selected by the snowball method. In the end, using experts' opinions, 24 variables were selected as effective drivers of Semnan's production-reproduction system of worn tissue. MicMac software was used for structural-interpretive analysis of variables. The results show that the rules and regulations governing the regeneration of the studied area are the most important and effective factors. Also, the special ownership conditions governing barren, ruined, and ruined lands have caused the private sector to have no incentive to invest in this area and reproduce the existing conditions. With the continuation of the current process, the existing situation is reproduced. Breaking this round of the reproduction process requires a constructive look at the target neighborhoods from the city administration and government agencies, which can provide the basis for the presence of private sector investors in these neighborhoods

Progressive collapse studies generally assess the performance of the structure under gravity and blast loads, while earthquakes may also lead to the progressive collapse of a damaged structure. In this study, the progressive collapse response of concentrically braced dual SYSTEMS with steel moment-resisting frames was assessed under seismic loads through pushover analysis using triangular and uniform lateral load patterns. Two different bracing types (X and inverted V braces) were considered, and their performances were compared under different lateral load patterns using the nonlinear static alternate path method recommended in the Unified Facilities Criteria (UFC) guideline. Eventually, the seismic progressive collapse resistance of models was compared to their progressive collapse response under gravity loads. These studies showed that models under the seismic progressive collapse loads satisfied UFC acceptance criteria and limited rehabilitation objective. The structures had better performance under seismic progressive collapse than models under gravity loads because of more resistance, ductility, suitable load redistribution, and more structural elements that participated in load redistribution. Furthermore, despite studies on progressive collapse under gravity loads, the dual system with X braces showed better progressive collapse performance (more resistance, residual reserve strength ratio and ductility) under seismic loads than the model with inverted V braces.

This paper attempts to analyze the semantic SPATIALIZATION of some abstract concepts in the language of Quran. It has been carried out based on Lakoff-Johnson's 1980 theory of cognitive metaphors-orientation metaphors. The main research question is whether concrete space concepts influence the transition of abstract concepts or those not related to place or space, and whether the mapping of these two concepts can be dealt with through cognitive theory of metaphor. For this reason, words, expressions, and metaphorical focuses denoting the spatial concepts of "front, back, near and far" were extracted from the Holy Quran. The findings show that the abstract concepts of "importance, attention and failure" are spatialized through FRONT/BACK concepts. Moreover, "greatness, enmity, and doing affairs" are the non-spatial ideas, conceptualized by "FAR/ NEAR" concepts.

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

One of the most frequent rules in various areas of demonstrative jurisprudence of Two Major Sects of Islam religion is a rule that is known among Shīʿa as “tolerance in the evidence of traditions” (Arabic: التسامح فی أدلّة السنن) and in Sunnī as “latitudinarianism in documents” (Arabic: التساهل فی أسانید). Believers in the general application of this rule have based it for reasons such as consensus (Arabic: إجماع), tradition famous through practice (Arabic: الشهرة العملیّة), and rational judgement (intellectual judgement) and a group of aḥādīth (Arabic: أحادیث, plural form for ḥadīth, literally “talk” or “discourse”) called “Akhbar-e- Man Balagh” (Arabic: أخبار من بلغ). The understanding of the aforementioned narrations and the extent of application of this rule has caused a conflict of opinions among scholars. The narrations containing the excellences of suras of the Holy Book of Quran is one of the fields of application of the rule of tolerance. The present research has explained the types of exposure to this group of narrations based on the rule of tolerance by using descriptive-exploratory method and using library sources and seeks to find a suitable approach about narrations of the excellences of suras (chapters) of the Holy Book of Quran. The interaction with these narrations is organized based on a special reading of the rule of tolerance in the selected approach, which is based on a rational interpretation of the contents of Man-Balagh (Arabic: من بلغ)’s narrations and is compatible with the indications of some verses and traditions. The use of weak narrations containing the excellences of suras (chapters) will be permissible based on this approach considering three conditions and without any certainty of attributing these narrations to Sharʿ (Islamic rules).

How to profoundly change the beliefs of the polytheists during the age of revelation from the denial of the Prophet (pbuh) to the certainty of his Message and the acceptance of his full guardianship is a question worthy of attention. The order of verses about prophecy based on the order of revelation is the reason to lead a transformative process and a special Quranic method in institutionalizing the belief of prophecy in the lives of Arabs. In the first stage, the Holy Quran in the first Makkī (Arabic: المکّیّ, suras revealed in Mecca) chapters has prepared the community from the motivational side to accept the truth of the Prophet’s (pbuh) prophecy and briefly stating the key issues surrounding it. The Holy Book of Quran at the time of the emergence of oppositions and doubts (the second stage) destroyed the arguments of the polytheists and explained the prophecy and proved its authenticity from a cognitive perspective in the second stage by presenting clear arguments. and the Holy Book of Quran in the third stage after Madanī (Arabic: المدنیّ, suras revealed in Medina) period has undertaken measures in order to fulfill the goals of the Massage by explaining the true position of the Prophet (pbuh) to deepen and operationalize the Prophetic belief through explaining practical duties for the Prophet (pbuh) and behavior based on the acceptance of Walaya (Arabic: ولایة, meaning “guardianship” or “governance”).

The current research was conducted with the aim of identifying the employment competencies of educational graduates from the perspective of view of employers. This research was applied in terms of purpose and was among the qualitative researches of Grounded Theory type. The participants of this research included 24 employers in the field of educational (interviewers for the Education recruitment exam, directors of non-state educational institutes, directors and recruitment officers of non-state schools, directors of kindergartens and preschools) in Birjand city. Data were collected using semi-structured interview and analyzed by Strauss and Corbin method and using MAXQDA-2020 software. In order to validate the research, two methods of member control and peer review or feedback were used. Consecutive review and comparison of data resulted in the extraction of 28 categories and 6 themes. Data analysis led to the formation of a sub-theory. The model shows that the focal variable is the process of education and teaching skills. The focal variable, under the influence of contextual and intermediate conditions, leads to the formation of the strategies of "being a lifelong learner", "research skills", "planning skills", "classroom skills and classroom management", "purposefulness" and "problem solving skills". became Finally, "increasing employability" was the consequence of this process.
