Кл.слова (ненормированные):
motion -- reference frame -- coordinate transformation -- velocity -- interval invariance
Аннотация: Based on the analysis and consideration of the features of Galileo’s transformations, new inertial and dynamic reference frames of movements are obtained. In the new inertial reference frame, the main drawback of Galileo’s transformations, associated with the violation of the invariance of the intervals between events, is eliminated. The developed dynamic frame of reference makes it possible to conduct effective studies of movements in force fields. Elements of this dynamic frame of reference intuitively, without a detailed analysis of the meaning of the transformations used, have been successfully applied in a number of scientific works in the field of physical electronics, devoted to the construction of theories of electron mirrors and cathode lenses. Obviously, the new reference systems indicated in the work will find wide application both in the field of research and design of electron-optical devices and ion-beam technological installations, and in other branches of fundamental and technical sciences.

Аннотация: The article presents the results of chemical analysis soils of drilling sites of the Sostinsky and Mezhozerny oil fields of the Republic of Kalmykia. The content of sodium ions is more than 2 times higher in both deposits. At the same time, the content of chlorides in some areas of the Mezhozerny field reaches its maximum. As a result, the soils are highly saline in terms of the degree of salinity and are mainly chloride-sulfate-sodium in terms of the type of salinity.

uranium ore -- internal standard -- elemental analysis -- ICP-NPP
Аннотация: This article discusses the features of the determination of elements in uranium ores of the Shusarysu uranium-ore province by inductively coupled plasma atomic emission spectrometry in comparison with the ore standard of Ore Research & Exploration (Australia). A multi-stage method of sample preparation for measurement is considered. The existing and developed methods for determining the elemental composition of uranium ores are focused, as a rule, on the determination of specific elements using regulated analysis procedures. However, during routine analysis, we need to quickly and efficiently determine a larger list of elements available with one instrumental method. Various methods are used to obtain multielement analysis, among which mass spectrometry and inductively coupled plasma atomic emission analysis are most popular due to their high performance and low detection limits. The listed methods work with solutions, therefore, it is necessary to pay great attention to sample preparation and instrument calibration.

Аннотация: In the course of continuation of scientific research in the development of Kazakhstani technology for the production of trimanganese tetraoxide pigment, there have been proposed new methods of analysis which make it possible to investigate new nanostructural materials sourced from local deposits. The results obtained are of practical importance and serve as the foundation for developing new technologically advanced domestic production of a competitive product that is in demand both on the national and international markets. The available methods are not able to highlight the particularity and diversity of Kazakhstani manganese ores due to the uneven distribution of manganese minerals and host (waste) rock, the quantitative ratio of rock-forming components and their variation instability. Methods of energy-dispersive analysis of manganese ores from Kazakhstani Zhaksylyk and Bogach deposits have been put forward, electronic micrographs, spectrograms of samples, diagrams of normalized distribution of elements on the surface of samples have been obtained and a comparative analysis with raw analogue samples of some foreign manufacturers has been performed.
