In order to protect the transmission lines against lightning strikes, it is important to investigate the tower grounding system. In this paper, a recent method called hybrid continuous circuit-trapezoidal integration method is used to calculate the impulse impedance of the grounding system. Moreover, conventional structures of the grounding systems have been simulated and the results show that, with the same wire length, the square with additional wire system has the least impulse impedance as compared to counterpoise, square and crow?s foot. Moreover, the effects of soil resistivity and lightning current rise-time on the impulse impedance of these grounding systems are investigated. It is concluded that the design of the grounding system depends on the geographic location of the site in terms of soil resistivity and isotropic characteristics of the area in terms of lightning current rise-time.

This study aims to describe 1) the form of cohesion contained in the news Watching Sakinah Movies, UIN Yogyakarta Give Praise Students and 2) describing the forms of coherence contained in the news Watching Sakinah Film, Students of UIN Yogyakarta Give Praise. The subjects used in this study were news of watching Sakinah film, UIN Yogyakarta students giving praise, and the objects used were sentences containing grammatical cohesion, a form of lexical cohesion. The approach used in this study is a qualitative descriptive approach. The data in this study are sentences in the news of Watching Sakinah Movies, This student is a method of literature study. While the method of data analysis in this study is descriptive method analysis method, the method used to analyze and describe cohesion markers and analyze markers of coherence. Test The results of the study show that in the news of watching Sakinah films, UIN Yogyakarta Beri Pujian students have varied markers of cohesion and coherence in the Tebuireng Online news discourse. Cohesion markers were found to reference (3), substitution (1), ellipsis (2), conjunction (3), collocation (1), and markers of coherence found cause-effect relationships (2), relationship coherence suggestions — goals (1), coherence temporal relations (1), and coherence of causal relationships (1).

The article is devoted to the research of the youth criminal subculture and its impact on the personality of under-aged. In the course of analysis of this negative impact, a definition of the criminal subculture of under-aged was proposed. The main principles of such a criminal subculture as AUE (the acronym, transcribed from Russian: АУЕ or А.У.Е., comes from «Арестантский уклад един» / “Prisoners Unity (Solidarity)” are defined. The reasons contributing to the development of this negative phenomenon and the typical fea- tures of a minor sharing the ideology of the AUE were identified. The methods for counteracting the AUE were proposed. The method- ological basis of the research is formed by general scientific methods: dialectical, system research method, analysis, synthesis, induction, deduction, analogy, etc., as well as such private scientific methods as comparative legal, formal legal, structural and functional, statistical ones. The authors relied on the results of research by Russian and foreign legal scholars, sociologists, psychologists.
