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).

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: It is considered that Norilsk ranks second in terms of atmospheric contamination. Industrial enterprises annually emit large amounts of sulphur dioxide, phenols, and heavy metal particles. The city is located within the Far North and is distinguished by the harsh climate of the subarctic type. The snow cover can lie from 244 to 277 days. Snow is a good sorbent; therefore, the snow cover accumulates solid and gaseous pollutants that enter it from the atmosphere with precipitation or are absorbed from it. The purpose of this study was to analyse the snow cover in the Norilsk industrial region and assess the state of atmospheric air in the winter. To achieve this goal, it is necessary to solve the following tasks: conduct a literature review on a given topic; take samples of snow in various industrial districts of Norilsk; study the dependence of the qualitative characteristics of snow on the sampling site; draw conclusions on the quality of snowpack in different areas of the industrial districts of Norilsk. In the course of the study, the following methods were used: organoleptic, visual, methods for determining water transparency, titrimetric analysis, etc. Heavy metal ions and sulphate ions were not detected in the thawed snow, so no industrial gas pollution was noted in the residential area. Most of the particulate contamination was caused by slagging of roads to improve vehicle traction.

ecological situation -- industrial city -- water supply -- public utilities
Аннотация: According to UN estimates, the shortage of safe drinking water can become one of the most acute and pressing problems. The specificity of this problem for Russia is not a shortage of water resources, but their pollution and ongoing degradation of water bodies. The quality of water is understood as the totality of its properties associated with the nature and concentration of impurities in the water. Water analysis is the only tool for monitoring its condition and properties. During the experiment, a team of researchers took samples of drinking water from the water supply network in various districts of the Norilsk industrial region, studied the dependence of the quality characteristics of water on the location and sampling method. Based on the findings, conclusions on the quality of drinking water were drawn. During the experiment, the authors found that in terms of organoleptic indicators, drinking water in all areas of the NIR meets the requirements of Sanitary Rules and Regulations and GOST. Taking samples at three control points of the Norilsk industrial region, it has been proven that the water is soft and its salt content is mainly due to the presence of hardness salts. Having made the necessary analyses, the authors found that the presence of microorganisms in the water supply network of the NIR is not significant, the permanganate oxidisability indicator does not exceed the requirements of Sanitary Rules and Regulations.

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.

Аннотация: Возделывание подсолнечника актуально в климатических условиях Западного Казахстана, характеризующихся высокой теплообеспеченностью и продолжительным вегетационным периодом. Для получения высокого урожая подсолнечника в системе адаптивных технологий важное значение имеет правильная предпосевная подготовка почвы и оптимальные сроки посева. Большой урон урожаю подсолнечника наносят сорные растения. Обладая мощной подземной и надземной массой, подсолнечник конкурирует с сорняками лучше многих других полевых культур. Тем не менее, на засоренных полях его урожайность, по данным ВНИИМК, снижается на 2,5 ц/га [48, 49, 50]. Как показали данные учета, в наших исследованиях 2018-2020 годов наибольшая засоренность посевов подсолнечника была на вариантах без применения гербицидов. Так, в среднем за 3 года в фазу 2-х настоящих листьев при применении технологии боронование + предпосевная культивация (контроль) на 1 м2 насчитывался 10,67 сорных растений с сырой массой 31,22 г/м2. Как показали данные исследований, в среднем за 2018-2020 годы наиболее высокий сбор масла установлен на варианте боронование + предпосевная культивация с внесением Раундап (2 л/га) – 9,57 ц/га. При применении 1 и 2-х междурядных обработок, совмещенных боронованием и предпосевной культивацией, сбор масла вырос до 7,16-7,95 ц/га, что больше по сравнению с контролем на 0,92-1,71 ц/га.

Аннотация: Механизм распределительных отношений по поводу обмена промежуточной продукции, ресурсов и услуг и распределение дохода от реализации конечной продукции на внешнем рынке является важнейшей частью экономических отношений внутри кластера. Распределительный механизм обеспечивает соблюдение интересов субъектов кластера и при этом механизм зернопродуктового кластера основан на том, что доходы от реализации конечной продукции распределены по цепочке технологического цикла, распределяются через цены, тарифы, централизованные фонды, которые созданы участниками кластера. В зернопродуктовом комплексе при использовании рыночных цен часть предприятий становятся прибыльными, одни – убыточными и при кластеризации данные процессы могут сохраняться. Важным звеном регионального зернового кластера являются крупные зерновые компании, холдинги, сосредоточившие крупные хлебоприемные предприятия по приемке, сушке, хранению и отгрузке зерна, они включают высокопроизводительные мукомольные предприятия, располагающие современной техникой международных производителей. В составе данных компаний находятся крупные, средние и мелкие сельскохозяйственные предприятия, производящие зерно, разработавшие свою технологическую стратегию и структуру производства, тактику, поведение на рынке, ценообразовательную политику

Распределительный механизм обеспечивает соблюдение интересов субъектов кластера и при этом механизм зернопродуктового кластера основан на том, что доходы от реализации конечной продукции распределены по цепочке технологического цикла, распределяются через цены, тарифы, централизованные фонды, которые созданы участниками кластера. В зернопродуктовом комплексе при использовании рыночных цен часть предприятий становятся прибыльными, одни – убыточными и при кластеризации данные процессы могут сохраняться. Важным звеном регионального зернового кластера являются крупные зерновые компании, холдинги, сосредоточившие крупные хлебоприемные предприятия по приемке, сушке, хранению и отгрузке зерна, они включают высокопроизводительные мукомольные предприятия, располагающие современной техникой международных производителей. В составе данных компаний находятся крупные, средние и мелкие сельскохозяйственные предприятия, производящие зерно, разработавшие свою технологическую стратегию и структуру производства, тактику, поведение на рынке, ценообразовательную политику
