Today, in the field of agriculture and animal husbandry, new meat and plant products called transgenic are created by genetic engineering, which due to its novelty, it will be necessary to study the position of the legislator and explain the restrictions and necessary conditions. In particular, scientific research has considered it detrimental to public health, and consequently the existence of dissenting and agreeing opinions, as well as legal gap (legal absence of required laws) in the relevant laws to ensure consumer rights and explain strong executive guarantees and other cases has made it one of the serious areas for jurisprudential and legal debates. In this study, while analyzing the arguments of those who believe in legitimacy, considering the possibility of applying rule of prohibition of detriment (rule of harm) in eliminating the expectant ((possible)) Shari'a rulings, as well as the rational and narrative obligation to avoid the expectant ((possible)) harm when the expectant ((possible)) harm is not negligible compared to the benefits that is motive on action and other controversies arising from their arguments, it seems that these products are not the permission for the mere possibility of loss when the obvious and apparent benefits are opposed to the expediency of preserving life and the right to health of the whole society and life. Therefore, it may be (possible) to establish a conflict between the permissibility (principle of permission and authorization) of taking this action and the observance of precaution in saving human lives, and according to the rule of more important instances exclude the important ones, the duty of mukallaf (obliged) should be clarified as in the questionnaires of a number of marā ji (authorities, source to follow or religious reference) have considered the precaution to leave this action. In particular, it can be seen that concerns about the Definite or potential risks reported have significantly changed the policy of developed countries in the consumption of these products and turned attention to the export market.

Due to its unique features and emergence of new concepts and meanings after the revelation of Quran, Arabic language has been the center of attention by the semantic experts from the beginning until the contemporary era. Among contemporary linguists and syntax analysts, Fazel Sameraii has also written some works, one of which is the book “ Aljomlat ol-Arabia val-Mani” . In this study, it has been tried to investigate and analyze this book in terms of both form and content. The results of the study show that this book is in line with the Islamic approaches, and the writer also has control of the authentic resources. In understanding Arabic sentences, Sameraii has used constructivist semantics. He also exploited role-oriented linguistics by making use of Maqam and style symmetry. Although he could not propose a comprehensive approach to the role of symmetrical relationships in semantics like Tamam Hasan, who developed the theory of symmetrical correlation, he mentioned the role of each symmetry in its own place, which was a success. However, in terms of form, the book lacks rudimentary and didactic tools. As well as the strengths, some suggestions have been provided concerning the weak points.

Proper names and Definite descriptions have been of controversial and essential issues in the field of philosophy of languuage and philosophers working on them have faced many problems. One of the most important problems is the problem of absurd names - descriptions. The present article first presents some of the most influential theoris. Such as those of Meinong, Russell, Frege, Strawson and Donnellan. Then studies the solutions provided for the mentioned problem and finally presents a new theory about proper names - descriptions.

In this paper, by using Mond-Pecaric method we provide some inequalities for connections of positive Definite matrices. Next, we discuss specifications of the obtained results for some special cases. In doing so, we use a-arithmetic, a-geometric and a-harmonic operator means.
