An algorithm for diagnosing errors in a computer training program for solutions of the control system characteristic equation using a numerical method is offered. Its feature is the formation of a product knowledge base for searching errors and using dichotomous tree in the process of diagnosis.Анотаці
Problems and prospects of higher education system development in modern society
Education as a subsystem of economy is a structural component of production, exchange, distribution, consumption and reproduction of economic values. At the same time, education produces specific value added, market commodity – educational service, and transforms an ordinary person into a rare labor resource under conditions of extremely dense specialization of economic activity. The decisive role in this process belongs to higher education. In the paper, the problem of development of the European higher school is considered. Attention is focused on priorities of European higher education, which are directed at improvement of the organizational structure and quality of scientific and professional training: internationalization and trans-nationalization of educational processes, higher education quality assurance, actualization and a rise of the level of doctoral training, development of the culture of academic autonomy and creativity of higher educational institutions as a guarantee of sustainable self-development, orientation to a harmonious combination of scientific studies, business and practical training. Basic trends of the experience of European countries in the mechanism of promotion of higher educational institution activity and formation of the educational system in Russia were considered

Cationic penetrating antioxidants switch off Mn cluster of photosystem II in situ
Mitochondria-targeted antioxidants (also known as ‘Skulachev Ions’ electrophoretically accumulated by mitochondria) exert anti-ageing and ROS-protecting effects well documented in animal and human cells. However, their effects on chloroplast in photosynthetic cells and corresponding mechanisms are scarcely known. For the first time, we describe a dramatic quenching effect of (10-(6-plastoquinonyl)decyl triphenylphosphonium (SkQ1) on chlorophyll fluorescence, apparently mediated by redox interaction of SkQ1 with Mn cluster in Photosystem II (PSII) of chlorophyte microalga Chlorella vulgaris and disabling the oxygen-evolving complex (OEC). Microalgal cells displayed a vigorous uptake of SkQ1 which internal concentration built up to a very high level. Using optical and EPR spectroscopy, as well as electron donors and in silico molecular simulation techniques, we found that SkQ1 molecule can interact with Mn atoms of the OEC in PSII. This stops water splitting giving rise to potent quencher(s), e.g. oxidized reaction centre of PSII. Other components of the photosynthetic apparatus proved to be mostly intact. This effect of the Skulachev ions might help to develop in vivo models of photosynthetic cells with impaired OEC function but essentially intact otherwise. The observed phenomenon suggests that SkQ1 can be applied to study stress-induced damages to OEC in photosynthetic organisms. © 2019, Springer Nature B.V
