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.

Modified sorbents and their application for extraction of metal ions. [Текст] / N. C. Murzakassymova, N. A. Bektenov, M. A. Gavrilenko // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №1. - P. 75-79

Аннотация: The data on accumulated mining waste in the territory of Kazakhstan are presented. Their processing has become very important in our time. The structure of surface-modified carbon materials with a grafted layer is given. New modified carbon sorbents were obtained, oleum was used as a modifying agent. It was revealed that the capacitive characteristics of the modified sorbent are significantly higher than that of the original one, which will make it possible to more efficiently extract the metal ion from wastewater and technogenic formations. Sorption is an effective method of extracting valuable components from wastewater and man-made formations. This method allows you to recover valuable substances with a high degree of wastewater treatment, which can be purified to the maximum permissible concentration of pollutants and then used in technological processes or in recycling water supply systems. Processing involves ores characterized by a low content of valuable components, fine dissemination and similar technological properties of minerals. The existing technologies for the development of minerals make it possible to use only a small part of the valuable mineral mass extracted from the subsoil, and the rest forms waste, which, as it accumulates and is stored, becomes one of the most significant factors of anthropogenic changes in the environment.

Аннотация: The most important task of the dairy cattle industry is to obtain high quality raw milk. To achieve it, a set of measures is required, including aimed at increasing the biological safety of produced raw materials. The aim of the study was to create a scientific and methodological basis for the Bovine leukemia virus (BLV) gene diagnostics in a combined format of pathogen indication and identification. This required updating the strategy of BLVPCR-RFLP genotyping, consistent with its phylogenetic classification, taking into account the growing knowledge about the genetic diversity of 11 genotypes of the studied viral pathogen. When staging nested PCR, oligonucleotide primers were used, which initiate at the final stage of the reaction the production of a 444 bp env-gene fragment of the pathogen. Five restriction endonucleases were used in PCR-RFLP BLV genotyping of: PvuII, SspI, AsuHPI, HaeIII, and BstX2I. As a result of verification of the developed Bovine leukemia virus method for gene identification with an updated genotyping strategy, a technical result was obtained, expressed in the ability to identify all 11 BLV genotypes discovered to date by interpreting the generated 58 genotype-associated combinations of PCR-RFLP profiles.

Аннотация: The main goal of the study was to develop and test an effective technology for cattle genotyping by the CSN3 gene based on real-time PCR with hybridization-fluorescence detection. There was developed a method for real-time PCR for cattle genotyping by A and B alleles of the CSN3 gene in the format of hybridization-fluorescence detection, involving the use of two 5/-fluorescence-labeled forward allele-specific primers, one reverse common primer, and one anti-primer labeled with a fluorescence quencher at the 3/-end of the oligonucleotide. As a result of practical studies aimed at testing the developed method, we obtained the technical result provided by the proposed technology, expressed in the effective identification of the desired genotypes due to correct interpretation of these curves of increasing fluorescence intensity, the results reliability of which was also confirmed by the well-known PCR-RFLP analysis technique for Bos taurus genotyping for similar allelic variants of the kappa-casein gene.

Спустя 1-1.5 дней после спаривания, самки откладывают яйцо в ночное время в течение недели. В лабораторных условиях самки откладывают яйцо по одному или беспорядочно на поверхности листьев (35%), снизу (45%), в стеблях (15%), на листьях чашек (5%), а на плодах почти не откладывают. После вылупления из яиц личинка прогрызает вход на мезодерму листа и проникает в него в течение 5 минут. Личинка T. absoluta имеет почти цилиндрическую форму, с четко выраженной головой, тремя парами грудных ножек и пятью парами брюшных псевдоножек.

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.

The proposed technology of continuous carbon-free selective extraction of zinc and lead from the dust of electric steelmaking production allows the use of lead production slag, which is fed into a rotating drum furnace in two oppositely directed streams. During the movement of lead slag in the furnace drum and the burning of the torch, lead and zinc are more completely extracted from the dust-like material, where the transporting object is compressed air, and the purified flue gas after the gas is further purified by means of a smoke pump is released into the atmosphere.

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.
