Аннотация: The article discusses three methods for predicting network equipment failures and the impact of the data array of input controllers. The purpose of the article is to reveal the relevance of the approach proposed by the authors to the use of large-amount of data in the chosen method of machine learning and to make a comparative analysis of the final values with the works of other world researchers. In the first section, the authors analyze the work of scientists from the Beijing University of Post and Telecommunications, noting the strengths and weaknesses of their method. In Section 2, the authors analyze the Holt-Winters method for developing algorithms for analyzing network traffic, which was applied by researchers from the Tomsk State University of Control Systems and Radio Electronics. In section 3, the authors applied the method of random trees in the modeling of machine learning methods of Rapid Miner Studio. The authors have carried out work with a large amount of data, and a comparative analysis of the results of modeling the method. The importance of using large amounts of information to train a model of network equipment failure forecasts is proved. In the final section, the authors highlight the need to improve forecasting models for its further implementation in the working environment. Also, the authors emphasize that the two articles considered by international researchers are a special case, as well as their chosen method for predicting failures in the LAN system.

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 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 object of research is technogenic mineral formations-tailings of the Bestube processing plant located within the Bestube gold field. Analytical and technological studies of stale tailings have been carried out. According to the results of analytical studies, the material composition of stale tails was established. The average gold content in stale tailings according to assay analyses is 0.565 g/t, silver 1.56 g/t. The tailings belong to the category of poor sulfide, oxidized raw materials. The main industrially valuable component in the tailings is gold, silver has a subordinate value, and other metals are not of industrial value. Mineralogical analysis established that stale tails are represented by quartz, muscovite, clinochlore, albite, dolomite. Studies were conducted on agitation leaching of stale tailings of the initial size (64.08% of the class –0.074 mm) and after additional grinding to the size of 90% of the class –0.074 mm. Reducing the size contributes to the dissolution of gold from the tailings: at the initial size, 66.28% of gold is dissolved, after regrinding the degree of dissolution of gold from the tailings increases to 87.23%. The results of research on agitation leaching of gold have shown a high efficiency of hydrometallurgical technology for processing stale tailings of a processing plant.

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: В условиях казахстанского Приаралья товарное рисовое земледелие сложилось в 1966- 1990 годы. В этот период построены инженерные оросительные системы, освоены рисовые севообороты, рис ежегодно возделывался на больших плошадях (90-110 тыс. гектаров). Это принесло огромные социальные, экономические, экологические изменения. Однако в условиях сокращения количества орошаемых вод развитие сельского хозяйства связывать только с повышением производства зерна риса невыгодно с точки зрения обеспечения продовольственной безопасности региона. Поэтому внедрение посевов повышает обший выход зерна. В настоящее время поставлена задача развития орошаемого земледелия (до 3 млн. гектаров) в других регионах страны. Следовательно, в условиях рисовых, хлопковых и кормовых севооборотов усовершенствование технологии возделывания ячменя имеет огромное значение. В связи с этим, увеличение площади посевов ячменя, разработка агротехники возделывания и внедрение его в производства имеет определенное практическое значение.
