Construction and application of a dynamic motion counting system for researching the properties of electron mirrors and cathode lenses. [Текст] / A. T. Ibrayev // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №6. - P. 114-120

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 addresses the analysis of the basic principles of administrative proceedings. The main attention is given to the identification of the main functions, the system and the hierarchy of principles. The scientific novelty lies in the study of important subordinate guiding principles, the influence of which is decisive for the principles of administrative proceedings, and hence the entire system of public administration. A brief overview of the basic principles of administrative proceedings and their implementation in the countries of the near and far abroad was made.

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.

Аннотация: In this work, we investigated a modification of a copolymer based on α-olefin (octadecene-1) (ODC) and maleic anhydride (MA) synthesized by the method of initiated radical polymerization. In the studies carried out, it was revealed that of all the synthesized copolymers based on maleic anhydride, the copolymer with α-octadecene was the most effective copolymer in reducing the viscosity of oil and TPT. In this work, a copolymer based on maleic anhydride and octadecene-1 (ODC – MA) was modified with primary amines – butylamine (BA), hexylamine (HA), hexadecylamine (HDA), octadecylamine (ODA), benzylamine (BzA).

Electrochemical behavior of cupronickel electrode in acidic media. [Текст] / R. N. Nurdillayeva // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №1. - P. 38-46

cupronickel -- Cu-Ni alloy -- alternating current -- titanium electrode -- hydrochloric acid -- electrolysis -- current density -- current efficiency
Аннотация: The electrochemical properties of the cupronickel electrode polarized by an alternating current in an aqueous solution of hydrochloric acid were studied for the first time. The electrochemical dissolution of cupronickel was carried out in a polarization mode with a frequency of 50 Hz in pairs with a titanium electrode. The current efficiency of dissolution of Cu-Ni alloys dependence on the current density at the titanium (20-120 kA/m2) and cupronickel (200-1200 A/m2) electrodes, the concentration of a hydrochloric acid solution (0.5-5.0 M), the electrolysis duration (0.5-1.75 h) and the alternating current effect (50-300 Hz) were considered. It was observed that the current efficiency of the alloy dissolution decreases linearly with increasing current density at the cupronickel electrode, while the current density at the titanium electrode passes through a maximum value at 60 kA/m2.
