Magnetic states in multiply-connected flat nano-elements

Flat magnetic nano-elements are an essential component of current and future spintronic devices. By shaping an element it is possible to select and stabilize chosen metastable magnetic states, control its magnetization dynamics. Here, using a recent significant development in mathematics of conformal mapping, complex variable based approach to the description of magnetic states in planar nano-elements is extended to the case when elements are multiply-connected (that is, contain holes or magnetic anti-dots). We show that presence of holes implies a certain restriction on the set of magnetic states of nano-element.Comment: 5 pages, 7 figure

INTERVALS OPTIMIZATION OF SYSTEMS INFORMATION SECURITY INSPECTION

A Markov model is suggested for secure information systems, functioning under conditions of destructive impacts, which aftereffects are found by on-line and test control. It is assumed that on-line control, in contrast to the test one, is char- acterized by the limited control completeness, but does not require the stopping of computational process. The aim of re- search is to create models that optimize intervals of test control initialization by the criterion of probability maximization for system stay in the ready state to secure fulfillment of the functional requests and minimization of the dangerous system states in view of the uncertainty and intensity variance of the destructive impacts. Variants of testing intervals optimization are con- sidered depending on the intensity of destructive impacts by the criterion of the maximum system availability for the safe execution of queries. Optimization is carried out with and without adaptation to the actual intensity change of destructive impacts. The efficiency of adaptive change for testing periods is shown depending on the observed activity of destructive impacts. The solution of optimization problem is obtained by built-in tools of computer mathematics Mathcad 15, including symbolic mathematics for solution of systems of algebraic equations. The proposed models and methods of determining the optimal testing intervals can find their application in the system design of computer systems and networks of critical applications, working under conditions of destabilizing actions with the increased requirements for their safety

ИСТОРИЯ ЗАКОНОДАТЕЛЬНЫХ ИЗМЕНЕНИЙ В СФЕРЕ СОХРАНЕНИЯ ИСТОРИКО-КУЛЬТУРНОГО НАСЛЕДИЯ РСФСР В 1980-е гг

The preservation of cultural heritage for many years was one of the main directions of the state cultural policy of the RSFSR. The relevance of the study is associated with the need for a comprehensive analysis of the impact of changes in state law on the protection of cultural heritage sites. This article is the first to examine the impact of the Law on the Protection and Use of Monuments of History and Culture, adopted in 1976 on the management and protection of cultural heritage sites, with the aim of determining the development of state policy in the protection of historical and cultural monuments. The methodological base is primarily associated with historical-systemic and historical-comparative methods. The main source of research was documents and legislative acts related to structural changes in the rules for the protection of cultural heritage in the RSFSR. The legislative framework of the system for the protection of monuments of the RSFSR has a rich past and the Law adopted in 1977 became a peculiar embodiment of all previous legislative acts adopted by the state in this area. Since there were several tens of thousands of monuments of various levels on the territory of the RSFSR, changes in the legislation were, to a greater extent, related to the clarification of the rules for use and improvement. In addition, changes in legislation punished inappropriate care of historical and cultural monuments. In the course of the study, the authors come to the conclusion that changes in the legislation assigned the rights and obligations of Soviet citizens within the scope of protection of monuments. An important place in the text of the new Law is occupied by a certain format for the grouping of monuments, which distributed objects of cultural heritage according to new lists

Updating of physical activity trained on the basis of lessons by professional and applied physical training

Transition of system of sports education to new standards of the third generation is the effective tool for updating of physical activity trained on the basis of lessons by professional and applied physical training.

Analysis of the communication policy of the regional department of KHMAO-Yugra «Nyagan center of employment of the population»

В статье анализируется коммуникационная политика краевого управления (КУ) ХМАО-Югры «Няганский центр занятости населения». Теоретическая и практическая значимость анализа коммуникационной политики в указанной организации обусловлена отсутствием теоретической модели коммуникационной политики и практическим отождествлением информационной и коммуникационной политики в деятельности центра занятости населения. Коммуникационная политика рассматривается в связи с интегрированием маркетинговых коммуникаций через систему функциональных аспектов: информационно-аналитического, мотивационно-целевого, планово-прогностического, содержательно-операционного, контрольной-оценочного, регулятивно-коррекционного.The article analyzes the communication policy of the regional Department (KU) KHMAO-Yugra «Nyagan center of employment of the population». Theoretical and practical significance of the analysis of communication policy in this organization due to the lack of a theoretical model of communication policy and identification of practical information and communication policy in the activities of the centre of employment of the population. Communication policy is seen as a complex of integrated marketing communications of the organization and target audiences through a system of functional aspects: information-analytical aspect, motivational target aspect, planning and forecasting aspect, content and operational aspect, monitoring and evaluation aspect, regulatory-corrective aspect

Colormetric system for monitoring the growth of microalgae Dunaliella salina under laboratory conditions

The brackish microalgae Dunaliella salina, being an extremophilic halophyte, is a promising object for biotechnological production. The aim of this work is to develop a methodology for non-destructive control of the development of a microalgae culture under conditions of balanced growth during periodic cultivation on plates. Before the start of the experiment, the microalgae culture was synchronized. The quantitative content of chlorophylls a and b, as well as carotenoids, was determined spectrophotometrically in alcohol extracts. During cultivation, time-lapse images were recorded on a smartphone camera. The basis of the colorimetric evaluation is the analysis of the time series of images in the RGB color model. It is shown that the ratio of colors correlates to a high degree with the content of the determined main plant pigments – chlorophylls and carotenoids, and with the data of spectrophotometric measurements of live suspensions. The changes in the blue channel are the most pronounced, the least being in the green channel. The logarithm of color intensity is linearly dependent on the degree of dilution of the culture. The developed method for real-time monitoring of the development dynamics of the D. salina microalgae culture makes it possible to build growth curves and solve multiparametric problems to optimize the cultivation of microalgae, including when working with large arrays of samples
