Concerns about the Islamicization of humanities make it necessary to offer objective criteria, and the science of education is no exception. Thus, attending the macro process of research is the most significant factor in the Islamicization of education. That is because the factor both makes it possible to explain the relationship between the scientific and religious aspects of Islamic education and facilitates responding to issues like the relationship between the divine message, reason, and experience, the status of efficacy, and the relationships between educational elements. The present study investigated discussions on the philosophy of science and Islamic education, and it was shown that the process of doing research in Islamic education was, similar to other sciences, made up of two stages (i.e., theorization and theory evaluation). The stages of theorization in that science started with theorization about educational goals, proceeded by investigating the foundations, principles, and other educational elements, and ended with theorization about educational issues. The results showed that the scientific dimension of the theories was approved when they reflected reality and were agreeable, generalizable, and coherent, while the religious dimension relied on their reference to the divine message. Thus, reliance on the divine message as the only source of achieving educational goals was considered the most significant factor in the Islamicization of science at the first step of the study, and reliance on divine educational goals with the assistance of reason and experience was theorized as the guarantees of achieving the specified goals in the investigation of the foundations and other educational components. Therefore, reference, efficacy, and internal and external coherence were introduced as the criteria to evaluate theories on Islamic education.

Connectors, which are components for connecting different types of conductors to each other and to other equipment in the power grid, are installed in large numbers in the medium and low voltage distribution network. Use of the general and international standards in the development of national standards related to these parts, without completing and developing specialized/supplementary guidelines for the characteristics of these parts that are less discussed in the general standards, leads to numerous problems, including spending a lot of time and money to repair and replacement of these parts, unwanted power outages and also high electric power losses. The present paper shows that such an approach in the development of national standards, while causing defects in more than 100,000 of these components each year, has led to relatively high power losses due to the presence of these components in the medium voltage distribution network. By developing optimal standards based on the technical/economic conditions of the country, the problems related to these parts can be greatly reduced. It is suggested that a technical committee be set up in the relevant national commissions to analyze the problems, provide solutions and develop optimal standards.

In this work, the effect of laser line interruption was studied on the structure and magnetic properties of grain-oriented silicon steel sheets during the laser-scribing process in the presence/absence of an external magnetic field. By applying different patterns of interruption, the effect of discontinuity length, one-sided or two-sided application of laser and overlapping or non-overlapping of laser lines (for sheets scribed on both sides) was investigated on the domain structure and core losses of silicon steel sheets. Based on the results of these experiments, the optimal conditions of discontinuous laser scribing were obtained. The results show that although at small interruption lengths such as 2 mm, the effect of laser scribing is negligible on reducing the core losses, but by increasing the interruption length to about 6 mm, the magnetic losses are greatly improved. By re-increasing the length of interruption to about 10 mm, the core losses increase again and this indicates that a break length of 6 mm creates optimal core losses in the sheets. Use of a longitudinal external magnetic field during the discontinuous laser irradiation with an optimum interruption pattern results in a reduction of about 16% in core losses in grain-oriented silicon steel sheets.

Al/Cu bimetals have many applications in power lines. During operation and due to the crossing electrical current, bimetals are heated and the temperature increases, resulting in microstructural changes and properties alternation in the interface areas. The aim of this article is to study aging treatment of friction welded Cu/Al bimetallic joint, in the presence of electrical current. Aging of bimetals was carried out under electric currents of 250 A and 500 A, which caused the components to warm up to initial temperatures of 150 °C and 250 °C, respectively. The results show that electrical current increase from 250 A to 500 A leads to increase intermetallic grows rate and increase electrical resistance. Also, the possible stable phases at the interface are CuAl2, CuAl, Cu4Al3, and Cu3Al2.

The issue of immigration is not a choice for Russia, but it is an essential factor for maintaining the rate of its population and labor force. However, Russian immigration policy is not comprehensive; it endures alack of clear expression of the goals. In addition, foreign immigrants are often not only accused of depriving Russian citizens of their social-economic rights, but also they are considered as a threat to the cultural and ethnic homogeneity of Russian society and national identity. This paper addresses the phenomenon of immigration both from the perspective of economic competition and nationalism, national identity, and ethnic prejudice. The author addresses the following question: "Why Russian major ethnicities, especially the Russians are mostly against the mass immigration to Russia?" The hypothesis examined in this paper is that "major Russian ethnicities especially the Russians are against the mass immigration due to the fear of immigrants’ incompatibility with culture and values of Russian society, rather than racial and ethnic prejudices." Using   library data and a descriptive-analytical methodology, the author tries to tell why the research findings provide an answer to the research question.

Kremlin insisting on the idea of BRICS as a diplomatic club of emerging regional powers for a decade and rebuilding this idea in order for challenging US domination over global economic institutions, parallel attempts of the BRICS in line with the US-led order, particularly with the Brett on Woods Financial system, has created an emerging network of partnership between revisionist powers with the goal of changing global governance. There is no doubt that BRICS is one of the most strategic forces to reforming international system as well as a novel strategic management. However, it is mostly about the difference between what Kremlin wishes for and what it gains. The main question of this study is "What are Russia's expectations regarding BRICS and to what extent these expectations are obtainable? "The initial response to the first part of the question is that "Russia expects that Brix by weakening US-led institutions in the management of the global economy and creating alternative regimes creates a multipolar international system including Russia as an important pillar". For the second part, the hypothesis has been tested that "although Brix's acts, considering continuing convergence the focus of the member states on the criteria of sustainable development and political governance, will lead to weakening US-led institutions and creating alternative regimes in long term, Russia's position in the coming order will remain similar to what it is. "The findings of the paper conducted by documentary-library methodology and analyzed through a causal method in qualitative and descriptive dimensions confirm the hypotheses.

The Russia – India – China Triangle is one of the first mechanisms that were used to encounter the US centered international order by the eastern powers which brought along the SCO and BRICS. Russia, India and China’s foreign ministers troika is actually an attempt for making a cooperation network among revisionist powers. Given the bilateral, trilateral and multilateral relations between the three mentioned countries, the question is whether such a goal is possible or not. The article’s achievement proves that although having relative potentialities and strong motivations for changing the US centered international order, the Russia – India – China Triangle is not capable of achieving the goal in the present situation. That is rooted in their diverse perception about the nature of this change and the position of each three country in the future of such a new order. Therefore strengthening the perspective of a change in international order is assessed as a positive measure for these players. Using an explanatory - analyzing method, the literature tries to find out the inefficiency causes in mechanisms of Russia – India – China Triangle.

This paper intends to review the performances of the Islamic Republic News Agency (IRNA) and the British Broadcasting Media (BBC) and compare the two domestic and foreign news agencies. Our main objective is to analyze the print and photo coverage of the 1012 London Olympic Games by IRNA and BBC. The methodology of this research is qualitative and content analysis has been used. Its statistical population is all the sports news stories aired by IRNA and BBC within the month-long 2012 Olympic Games. BBC posted a total of 123 news stories of which 120 were reviewed in this study. From among 1000 news stories covered by IRNA, 120 were selected on the basis of systematic random sampling method and SPSS was used to analyze the data. The findings of the research indicate that there is a significant difference between the performance of the two news agencies in the fields of type of subject, photo, news writing style, news elements and news coverage on the basis of gender; that is the stories are event-oriented, pictures are archived ones, the news writing style is inverted pyramid and the news elements of ‘what’ and ‘who’ are used by IRNA more than BBC, while the latter showed more attention to stories about female athletes. On the subject and news values there was no significant difference from statistical point of view between the two news agencies.
