Genetic school of Leningrad-St.-Petersburg University had been shaped up on the background and simultaneously as a witness of achievements of the Russian genetics in 20-30-th of the XX century. The process had been strongly influenced by the personal relations of Yu.A. Filipchenko, the founder of department of genetics and experimental zoology of Petrograd University, with Russian (N.K. Koltsov, N.r. Vavilov at al.) and foreign (Т.Н. Morgan and his students first of all) colleagues. An episode is presented about formation of contemporary theory of mutation process by the efforts and cooperation of several scientific schools: by work of G.J. Muller, N.V. Timofeev-Ressovsky, M.E. Lobashev etc

The article deals with Russian traditions of studies of foreign countries which have become an intellectual pillar for Russian economic expertise. The modern application of experience of Soviet scientific schools in international studies is shown, especially in the fields of world development forecasts, analysis of Russian foreign economic relations and research of economic policy abroad. The article is based on open sources with publications, reports and presentations about expert and analytical activities of the Institute of World Economy and International Relations (IMEMO) and other institutes of the Russian Academy of Sciences, VNIKI-Institute, MGIMO-University and some other centers. It is explained that results of international studies have become a necessary element for consulting of governmental bodies and businessmen in the epoch of globalization.

In what follows I will develop an account of Fairbairn's object relations theory as I have understood and developed it, and, apply that theory to an understanding of the threeact opera King Roger, Op. 26 (1926) by Karol Szymanowski. My Fairbairnian approaches to the opera come from my previous work on Fairbairn's object relations theory. In order to fully understand the first of the approaches I employ you may need to read my book Personal Relations Theory (Clarke, 2006), in particular chapters one, five, and six. In order to fully understand the second of the approaches I am using you need to read Thinking Through Fairbairn (Clarke, 2018a), in particular chapters two, three, and four, as well as my paper in the journal Attachment (Clarke, 2018b) on MPD/DID and Fernando Pessoa's heteronyms.

This research is motivated by the lack of ability to write simple words first grade students of SD Negeri 014 Pagaran Tapah Darussalam Rokan Hulu. This study aims to improve the ability to write simple words first grade students of SD Negeri 014 Pagaran Tapah Darussalam, held for 1 month. The subjects were students of class I SD Negeri 014 Pagaran Tapah Darussalam academic year 2015/2016 the number of students as many as 7 people, consisting of 5 boys and 2 girls. Form of research is classroom action research. The research instrument consists of instruments and instrument performance data collection activity observation sheet form teacher and student activity. Based on the results of the study it can be concluded that the ability to write simple words can be enhanced through training methods first grade students of SD Negeri 014 Pagaran Tapah Darussalam. This statement can be accepted, because the students' ability to write simple words increased. Where known from preliminary data the average value of 59.3 or in the medium category. When viewed from the classical completeness, there is 28.6% or 2 students who completed gain value according to standards KKM, which is a minimum of 65. However, after the implementation of training methods, obtained an average value of 67.1 or higher in a category. When viewed from the classical completeness has reached 57.1%, or 4 students, but research has not been successful. Because this study was successful when 85% of students obtaining a minimum value of 65. While on the second cycle, to reach an average value of 80.7 or higher in a category. When viewed from the classical completeness, has acquired all of the students (100%). Thus, the researchers limited the study to the second cycle. Because of the results obtained was clear, that improve the students' first-class students of SD Negeri 014 Pagaran Tapah Darussalam in writing simple words.

Introduction: The Hadamard conjecture about the existence of Hadamard matrices in all orders multiple of 4, and the Gauss problem about the number of points in a circle are among the most important turning points in the development of mathematics. They both stimulated the development of scientific schools around the world with an immense amount of works. There are substantiations that these scientific problems are deeply connected. The number of Gaussian points (Z3 lattice points) on a spheroid, cone, paraboloid or parabola, along with their location, determines the number and types of Hadamard matrices.Purpose: Specification of the upper and lower bounds for the number of Gaussian points (with odd coordinates) on a spheroid depending on the problem size, in order to specify the Gauss theorem (about the solvability of quadratic problems in triangular numbers by projections onto the Liouville plane) with estimates for the case of Hadamard matrices. Methods: The authors, in addition to their previous ideas about proving the Hadamard conjecture on the base of a one-to-one correspondence between orthogonal matrices and Gaussian points, propose one more way, using the properties of generalized circles on Z3 .Results: It is proved that for a spheroid, the lower bound of all Gaussian points with odd coordinates is equal to the equator radius R, the upper limit of the points located above the equator is equal to the length of this equator L=2πR, and the total number of points is limited to 2L. Due to the spheroid symmetry in the sector with positive coordinates (octant), this gives the values of R/8 and L/4. Thus, the number of Gaussian points with odd coordinates does not exceed the border perimeter and is no less than the relative share of the sector in the total volume of the figure.Practical significance: Hadamard matrices associated with lattice points have a direct practical significance for noise-resistant coding, compression and masking of video information.

Overview of the research results got by various scientific schools in the field of application of ultrasonic surface hardening is provided. Wide range of opportunities of ultrasonic surface hardening is shown for the application in the preliminary machining of surfaces before thermal and chemical treatment, coating, and also as finishing machining. The effect of the energy of ultrasonic vibrations on structure changes in the material of the surface layer and on surface microrelief on parts performance is considered. The prospects of using of the ultrasonic surface hardening method in combination with other methods of the material modification are presented. In addition the possibilities of reducing the manufacturing cost of product by introducing ultrasonic surface hardening into the technological process are shown.
