Layered perovskites, including the Dion-Jacobson phases, are of interest to researchers due to a wide range of revealed properties. Among them there are compounds with high photocatalytic activity, ionic conductors, ferroelectrics, piezoelectrics, ferroelectrics and luminophores, as well as materials with unique magnetic properties. However, the properties of these materials largely depend on the method of synthesis and the precursors used, so the study of the possibility of obtaining layered perovskite-like compounds of various compositions remains relevant. The purpose of this work is to study various literature sources, to identify the possibility and methods for obtaining pure phases with the Dion-Jacobson structure, to consider the areas of application of these compounds, and to establish prospects for further research.

This research aimed to investigate the peculiarities of the emotional intelligence of basketball players of different levels of mastery. The study involved 33 average levels of mastery and 33 high levels of mastery sportsmen. The Schutte Emotional Intelligence Scale (SEIS) was used in the study. The results of this study revealed that appraisal of higher-level mastery basketball players was statistically significant (p < 05) higher than sportsmen's average level of mastery. But the optimism (p < 05) was higher for the average level of mastery players. No statistically significant differences in overall emotional intelligence estimates were found between average and higher level of mastery basketball players.

The study aimed to find out the differences in athletic identity between young (16–18 years old) basketball players. It was found that many indicators of the athletic identity of young basketball players selected for the national team were higher than those not invited to the national team. For they were highly expressed the negative affectivity.

The article focuses on the main driving forces that force telecom operators to introduce the latest achievements of scientific and technological progress into their networks and provide subscribers with new opportunities and advantages. One of the latest advances in the world of telecommunications is the IP Multimedia Subsystem (IMS). Based on literary sources, a review of the IMS concept is carried out, the main ideas embodied by it are highlighted. The paper provides a solution for the implementation of virtual IMS technology in the telecommunications network infrastructure, defines the main network equipment on which the functional components of the vIMS network are implemented.

Fermat's Last Theorem has been proved on the basis of school Physics, Mathematics, analytical Geometry. The main conceptions of the proof one can write on a math toy in the form of a wooden cube for children. Six faces of the cube are enough to deliver the main ideas of proof.

The aim of the study is to reveal the peculiarities of mental toughness among cadet and junior basketball players. To achieve this goal, the MTQ48 questionnaire (Mental Toughness Questionnaire 48) was used as a methodological toolkit. The results showed that cadets have higher scores on the «Reaction to the Challenge» and «Control» scales compared to junior players.

The article discusses the basic principles of the operation of Blockchain technology, its advantages and disadvantages. Particular attention is paid to the role of Blockchain in the development of a digital society. Various areas of application of this technology and features of use are shown.

This work is a continuation of a series of articles devoted to the development of the physics of «vacuum» on the basis of the axioms of the Algebra of Signatures. In this part of physics of the «vacuum» the overall dynamics of vacuum layers, and in particular of «vacuum electrostatics», are considered. The rotation of the vacuum layers within the core of the stable vacuum formation (in particular the inside cores of the «electron» and «positron») is investigated.

This paper is a continuation of a series of articles devoted to the development of light-geometry of the "vacuum" based on the axiomatics of the Algebra of signatures. In this part of the light-geometry of the "vacuum" the general dynamics of the vacuum layers is considered, from which under certain conditions "vacuum electrostatics" follow. The ways of studying vacuum layers rotation inside nuclear of stable vacuum formations, in particular inside the nuclear of the "electron" and "positron", are outlined.

The work presents a technique for image processing of aluminum alloy D16T experimental samples metallographic sections after erosion testing with variable parameters of high-speed drop impact.

The aim of the study is to compare the indices of mental toughness among basketball players and track and field athletes. To achieve this goal the questionnaire MTQ48 (Mental Toughness Questionnaire 48) was employed. The results showed that track and field athletes have higher scores on the "Reaction to challenge" and "Control" scales compared to basketball players.

This work considers questions of origin and formation of the Yaroslavl football club «Shinnik». The characteristic of infrastructure of the stadium is given, as it was planned to carry out its reconstruction initially by 2010 in honor of the millennium and further inclusion of stadium in the list of the cities in which the FIFA World Cup will be held is studied. Statistical data of victories and defeats in various years of existence of club are provided in work.

The article examines the intensity of secondary successions of vegetation in abandoned agricultural areas in submountain regions of Crimea. Floristic, age and quantitative range of the «pioneers» species of these phytocenoses’ settlement are identified by conventional forest inventory and geobotanical methods. The research proves the formation of transitional communities consisting of primary forest vegetation and grassy glade complexes with plenty of ruderal species and intensive mosaic grass stand, therefore secondary demutations are under discussion for decades.

The article discusses the most common platforms for creating virtual machines. The authors also ask questions about the definition of virtual machines and their target causes, based on a comparative analysis of the main characteristics.

The purpose of the study was to compare the performance of tactical and technical actions of playing activities among strikers of Continental and Higher Hockey League (KHL and VHL). To achieve this goal analytical method was employed. As the material was used individual performance statistics of twenty best strikers of KHL VHL in the season 2014-2015, published on the official sites of the championships.

Authors of this article note that one of the widely used in practice methods of strength calculation of structures is the finite element method (FEM). FEM is a procedure of approximate solution of differential equations. It was originally designed for solving problems related to the calculation of strength of structures, that is, to calculate forces, stresses and strains in solids.

The subject of the paper is the internet newspaper. Being based on a printed newspaper, an internet newspaper is viewed as hybrid, which means that it combines traditional parameters of the prototype and means of information organization and presentation peculiar for the Internet. Among them there are special graphic issuance of text, multimedia features, hypertextuality, a multilayered construction and interactivity.

The peculiarities of the willpower construct components of young basketball players (16–18 years old) were studied. The study used a questionnaire to evaluate the nine components of the willpower construct. It was found that the scores of most willpower components of young basketball players who achieved higher mastery were significantly higher than those of peers who trained together but had lower athletic achievements.
