Monitoring and evaluation of transformers are essential to prevent their insulation failure. In this paper, the use of 2-furan-carboxaldehyde (2-FAL) and methanol (MeOH) concentrations as the main products of paper insulation degradation, and insulation condition markers, has been studied. In order to study the degradation process and production of degradation products, the thermal aging process of the transformer insulation system was implemented in laboratory conditions. The results of laboratory studies show that in the early stages of degradation the amount of MeOH is significant compared to 2-FAL. Also, the estimation of the degree of polymerization (DP) in the early stages of degradation (DP>800) through MeOH concentration and with decreasing DP (DP <800) through 2-FAL concentration is closer to the real value. The results of studies performed on 35 distribution transformers confirm the production of significant amounts of MeOH in the early stages of degradation. Also, the estimated DP values for the studied transformers were obtained through 2-FAL and MeOH concentration. The results show that estimating the amount of DP through MeOH concentration is associated with a probability of error of about 9% compared to estimating DP through 2-FAL concentration.

To investigate the effects of fertilizer regimes on quantitative and qualitative traits of Dracocephalum kotschyi Boiss, a field experiment at three replications with the Split Plate arrangement in a completely randomized block design was conducted in the Research Field of Tarbiat Modares University during the 2017-18 growing season.Water deficit stress (irrigation after discharging 20 (optimal irrigation), 40 (mild water deficit stress), 60 (moderate water deficit stress) and 80% (severe water deficit stress) of water used (available water)) in the main plot and fertilizer regime (urea, nitroxin, vermicompost, azocompost and no fertilizer) in the subplot were studied. The results showed that the highest leaf fresh weight (1797 kg ha-1) and total biomass (2957 kg ha-1) were obtained by application of urea in mild water deficit stress condition and the highest dry matter digestibility percentage was observed in azocompost treatment in moderate water deficit stress condition (57.8%). The highest crude protein was produced in severe water deficit stress condition (19.72%) and moderate water deficit stress (18.4%), respectively.. The highest percentage of water soluble carbohydrate and neutral detergent fiber were obtained from no fertilizer in moderate water deficit stress (22.06%) and application of urea in severe water deficit stress conditions, respectively. Mild water deficit stress application to produce high biomass is recommended for Dracocephalum kotschyi Boiss. According to the results, application of urea in mild water deficit stress was selected as the best treatment to produce forage 32% more than control.

To optimize tomato (Solanum Lycopersicum) plant tissue culture condition, the effect of 13 different hormonal combinations and two explants of cotyledon and hypocotyl on the regeneration rate of three Newton, Infinity and Defines cultivars were investigated. Experiments were conducted in a factorial based on a completely randomized design with three replications. The highest shoot number (11.9 shoots per explant) was obtained for Defines cultivar on MS medium containing the hormones of TDZ=0.68, NAA=0.1milligrams per liter and cotyledon explant. Plant defense responses against environmental factors are one of the inhibitor factors of explants regeneration in plant tissue culture. Calcium ion signaling is one of the primary events and, of course, the most important event in plant defense response against pathogens, Therefore, the effect of verapamil as a calcium channel blocker was investigated on the plant defense response. For this purpose, inoculation was performed using Agrobacterium tumefaciens strain LBA4404 and based on optimized tissue culture condition. The effect of verapamil in four concentrations of 0, 50, 100 and 200 milligrams per liter was investigated in a co-culture medium. Results showed that the use of verapamil in comparison with the control sample reduced the plant defense response. Also, the use of 50 milligrams per liter of verapamil increased the amount of regeneration

Purpose: The present research aimed at finding an answer to the question of the process of influence of cyberspace on Iranian Poetry in the future, and the influence of cyberspace on various aspects of poetry such as content, its audience, the poet, the media that published the poem, the process of composing the poem, the rights of the author, and Globalization of the Iranian poetry. Method: The Delphi technique was used to carry out this research. A group of experts comprising professors in the fields of Communication and Literature was selected. The expert’s opinions were collected and analyzed through an in-depth interview, a questionnaire based on the Likert scale, and by the execution of three stages of Delphi rounds. Findings: Accordingly, considering the content, the experts predicted that due to the impact of cyberspace, the quality of the poetry will be reduced and consequently, the language of poetry will become simpler and close to prose and it will only reflect the daily events of life. Regarding the audience, they concluded that the audience’s selection power will be increased, however, we can differentiate between the public and professional audience. With respect to the sender, there will be no phenomenon of multi authors, and regarding the channel, the experts agreed upon Media Convergence besides, the poets’ agency in publishing their own poems will be increased. Conclusion: Experts believe that the spread of communication technologies will make censorship ineffective. This is the only case in which the group believes in the impact of technology on the future of poetry. The group of experts did not reach a consensus regarding the impact of technology on the phenomena such as publication of author’s poems as one’s original work and the Globalization of Iranian poetry, thus, analyzed these items in the framework of the human agency.

Due to its special natural and geographical conditions, the city of Tonekabon is susceptible to many shocks, including earthquakes and floods, which brings the need to pay attention to urban resilience. The present study was conducted to analyze the state of urban neighborhoods from the perspective of urban resilience components. This research is applied in terms of purpose and descriptive-analytical method. The research's statistical population was comprised of citizens living in Tonekabon city. Using Cochran's formula, the statistical sample size was estimated to be 384 people. The data collection tool was a questionnaire, the validity of which was verified in the form of face and face validity, as well as divergent validity and reliability of the questionnaire using Cronbach's alpha and composite reliability. Analysis of data and information was done using SPSS and PLS software programs. The findings of this research showed that the overall resilience of Tonekabon city is in an unfavorable situation. In such a way, the average experimental value obtained for the overall resilience of the city and its dimensions was lower than the average value of 3. Among the localities of the studied area, Karim Abad neighborhood, in which the overall average obtained was equal to 2.78, was in a better condition than other localities, and Tonekabon neighborhood, according to the average (2.39), was in an unfavorable condition among the studied localities. Among the other research findings, among the components of urban resilience, the physical factor with a path coefficient of 0.490 has the most significant impact and was ranked first, followed by the economic factor with a path coefficient of 0.348. In third place is the administrative, institutional factor with a path coefficient of 0.327 and in fourth place is the social dimension with a path coefficient of 0.264.

Purpose: Something that happens in the future of a scientific field depends on today's view of young people about the future. The perception of young people from the future and their conception of the future is very important. The purpose of this study was to imaging the future of sports science from the perspective of educated youth. Method: The method of the present research is qualitative and exploratory research and in terms of purpose is applied research. The statistical population of the study included educated youth who are familiar with sports science and the snowball sampling method was used for interviews and theoretical saturation were obtained with 23 interviews. To analyze the data, the content analysis method has been used to obtain the information of this research. Findings: The results show the future of sports science among educated youth consists of seven main concepts that include: hope for a green education system, excessive interest in working in the sports industry, basic reengineering, relative disappointment from the ability of authorities, social position through academic education, desire for empowerment and lack of skills, injustice, and utilitarianism. Conclusion: Finally, by observing the mental images of the youth, it can be stated that sports science will move towards the dystopia if the current situation continues, and it can move towards the utopia with fundamental changes. In this direction, the stakeholders of sports sciences need to be together and disagreements need to be managed as well as arbitrariness of sports science professionals should be reduced.

Four important ways of religious education in the field of beliefs are inferred in this article through the nature of religion in the Holy Quran. We have examined two categories of “nature of religion” and “methods of religious education” for this purpose. All verses including the root of “د ـ ی ـ ن” (religion) have been investigated in order to properly understand the nature of religion in the Holy Quran. Then, we have benefited from the inference method to find the ways of religious education in the Holy Quran. In the inferential method, we have reached the “conclusion”, which is the method of religious education by using two premises, “normative” and “realistic”. The solutions of the Holy Quran to achieve the methods of religious education are explained in the following. For example, using the Scriptures directly to know the right actions is one of the solutions of the Holy Quran to reach the way of believing in the punishment of deeds. The achievement of religious education methods through discovering the nature of religion and explaining the purpose of education on the one hand and using the inferential method as a research method on the other hand is one of the innovations of this research. The achievements of this paper can be used to provide an educational theoretical model for formal and public education system.

1برنامه درسی به عنوان ستون فقرات نظام آموزشی، یکی از عوامل مهم در راستای ایجاد تحولات بنیادین در نظام آموزش عالی به شمار می رود؛ هدف این پژوهش تبیین مدل اثربخشی آموزش کارآفرینی از دیدگاه اسلامی و آرای مقام معظم رهبری است تا بتوان با آن برنامه درسی آموزش معماری را، از نظر تحقق مولفه های کارآفرینی در دانشجویان بررسی کرد. روش پژوهش حاضر آمیخته اکتشافی است که در قسمت کیفی با بررسی آرای مقام معظم رهبری در مقالات، کتب و سخنرانی های ایشان، گزاره های توصیفی از اندیشه ایشان در خصوص اثربخشی آموزش کارآفرینی، با روش دلالت پژوهی استخراج شد. در بخش کمی داده ها با استفاده از روش معادلات ساختاری و با استفاده از نرم افزار SPSS20 و  smart PLS مورد تجزیه و تحلیل قرار گرفت. یافته ها نشان داد که الگوی کارآفرینی از دیگاه مقام معظم رهبری، در چهار رکن اصلی: بینش، دانش، مهارت و کسب و کار قابل تقسیم بندی است. و هر یک از این رکن های اصلی با الگوی اثربخشی آموزش کارآفرینی در برنامه درسی معماری همپوشانی دارد. بدین ترتیب مراکز آموزش عالی معماری می توانند در کنار ایجاد برنامه های درسی کارآفرینی در رشته معماری، با شناسایی پتانسیل های موجود در برنامه های درسی این رشته، به تقویت نقاط قوت و رفع نقاط ضعف موجود در آن ها بپردازند. این الگو ضمن فراهم کردن شرایط تحقق آموزش کارآفرینی در رشته های دانشگاهی، زمینه اجرای یک الگوی بومی را در پرتو دستورات اسلامی فراهم می آورد.
