    The technology of MEMS atomic cells containing rubidium or caesium vapors in an atmosphere of neon buffer gas has been developed. Two-chamber silicon cells containing an optical cavity, shallow filtration channels and a technical container for a solid-state alkali source have been implemented in a single-step process of anisotropic wet chemical etching. To prevent significant undercutting of the filtration channels during etching of the through silicon cavities, the shapes of the compensating elements at the convex corners of the silicon nitride mask have been calculated and the composition of the silicon etchant has been experimentally found. The sealing of the cells has been carried out by silicon-glass anodic bonding at a temperature of 250 оС. For this purpose the LK5 glass which has an increased ionic conductivity in comparison with the conventional glass Borofloat 33 was used. The best microfabricated cells allowed us to obtain estimates of the relative instability of the coherent population trapping resonance frequency at the level of 5·10-11 at 1 s

    © Serials Publications.Relevance of organizing socially oriented education is caused by multinational and multicultural society in almost every country nowadays. It assumes the analysis of principles and conditions that allow to construct socio oriented educational process. The purpose of the article is to characterize features, which educators should form in their pupils choosing special educational activities, forms, methods and techniques. The leading approaches to research of this problem are intercultural, problem and communicative ones, allowed to define principles, and goals of tutoring in multiculturalism. The main results of research consist in systematization of a technique of forming socio-oriented qualities at students. In order to realize principles a number of requirements were defined: involvement into educational activities not only the educational staff, but representatives of governmental, and civic structures and development of significant qualities of personality at socially significant level: both cultural and public and at individually significant level Materials of the paper can be useful for university teachers and post-graduate students

    Despite that fact that cross-border tourism and recreation in the Baltic Sea Region have been extensively studied, there are still areas, which require further research. The aim of this article is to identify regions having active cross-border tourism and recreation in the adjacent territories of Finland and the Republic of Karelia. The authors propose to use an indicator characterizing the volume of incoming tourist flows. The number of tourists is not only indicative of the development of cross-border tourism and recreation; it is also one of the main criteria for determining the degree of the formation of cross-border regions. Using the statistics for Finland, the authors analyzed the geography of tourism in Finland's border areas and identified the degree of intensity of cross-border tourism exchange between the neighbouring administrative units of the two countries. The article also examines other tendencies indicative of the formation and development of cross-border tourism and recreation regions along the Russian-Finnish border. The authors identified three cross-border tourism and recreation regions of different development levels: South Karelia, Middle Karelia and North Karelia. South Karelia is a mesoregion with the average annual tourist exchange of about 100 thousand people, which is the average level of tourism development. The total volume of cross-border tourist flows from and to other cross-border tourist and recreation regions is about 30 thousand people per year. Middle Karelia microregion ranks second and is followed by the North Karelian microregion. The authors conclude that these two microregions are at the initial stage of their formation and, therefore, can be regarded as parts of one microregion - Russian-Finnish Northern microregion

    Get PDF
    Purposes: Increased international activity in Russia leads to a steady claim of foreign language knowledge. The list of professional characteristics of a university graduate includes the ability to adapt to new information realities in the professional community, where foreign language speech activities become highly demanded, when not only language skills, but also social and cultural arrangements of the country. Thus, innovative approaches to foreign language teaching are required. The article explored the following aspects of foreign-language speech activity of university students. Methodology: methodology of teaching foreign-language speech activity; principles of development of foreign language speech activity of students; realization of educational resources for this activity development; model of pedagogical technology of formation of foreign language speech activity, etc. Result:  The results of the pilot work showed the validity of using the principles of the development of foreign language speech activities in the organization of the educational process. Implications/Applications: This article will help the student to promote the ability to give a speech. Novelty/Originality: At the same time, being a type of speech activity, foreign language communication in the process of training solves, in turn, educational and development tasks by means of a foreign language sign system, where the whole set of speech actions of the individual is actually present

    © Author(s).Learning a foreign language is becoming an increasingly important with Russia's integration into the world community. In this regard, increased requirements for the educational process and the development of new innovative teaching methods meet the requirements of the time. One of the important aspects of learning a foreign language is listening as a kind of verbal activity. The study showed the importance of the problem of improving the mechanisms for listening in non-language faculties of the university. The article describes the relevant aspects of the difficulties of the process of listening, the essence and the main characteristics of this type of educational process and the criteria for high-quality listening in a non-language high school. The study describes a system of training of listening within the most effective exercises; learning of listening as speech culture; methodology of teaching a foreign language, which is subject to the general requirements of higher education, where listening becomes a part of developing the system of education. The results of the experimental work show the effectiveness of formation of the basic skills of listening as a speech and language in general, the successful development of students of non- language specialties of high school

    Received: 01.12.2021. Revised: 13.12.2021. Accepted: 14.12.2021. Available online: 15.12.2021.The possibility of obtaining cyclopentanone by pyrolysis of calcium adipate at different temperatures was considered. The pyrolysis proceeded with the formation of cyclopentanone and cyclopentene. The use of metal salts and metal oxide catalysts for the dehydrogenation of lower alkanes makes it possible to increase the yields of the target products. The best results were achieved in the presence of a «K-16u» catalyst

    © 2016 by iSER, International Society of Educational Research. The article reveals the essence of the phenomenon of multiculturalism in education as the construction of the learning process on the principle of cultural pluralism, contributing to the formation of a multicultural identity through the deliberate creation of a foreign language environment, formed and developed in the subject of multicultural thinking. The study identified and systematized the main approaches to understanding the problems of multicultural education (cultural and ethno-psychological); analyzed its basic principles (humanistic, cultural conformity, multiculturalism, social and evaluative, creativity); isolated components, factors and barriers of multicultural education; defined personality human culture and success criteria for their development in a multicultural educational space of a non- language high school, as well as the criteria for selection of educational material, having based on the study of a foreign language high multicultural potential. As the results of the experimental work proposed in the study, pedagogical conditions justified the thesis of the need to develop the student as a person of culture in a multicultural education in non-language high school
