The main task of microbiological study of pulmonary patients is to identify the etiology of acute and exacerbation of chronic disease in order to determine therapy and control its effectiveness. Classical methods of microbiological research consist in isolating a pure culture of the causative agent of the disease with its identification by biochemical, antigenic and other characteristics. Such studies are multistage; they impose rather strict requirements on the quality of the source material, the timing and conditions of its transportation, laboratory equipment and the precise execution of the research methodology for at least 3-5 days. Isolation of the culture of a number of pathogens (atypical intracellular microflora, anaerobic bacteria, mycobacterium tuberculosis) requires even more lengthy studies using special media and equipment. This article presents the results of a bacteriological study of pathogenic microflora in diseases of the respiratory system of the population of the Shcherbakty district of Pavlodar region for 2017-2019, including the following sequence: microscopy of native and Gram stained smears; inoculation of biological material on nutrient media for isolation and identification of the pathogen; determination of the sensitivity of the isolated microorganism to antibiotics; immunological (serological) research methods aimed at determining antigens of microbiological origin, as well as antibodies to them in the patient's body. It has been shown that conducting bacteriological studies in accordance with the requirements of regulatory documents allows obtaining reliable and comparable results necessary both for the optimal treatment of patients and for collecting and analyzing data on monitoring the emergence and spread of diseases of the respiratory system caused by pathogenic microflora.

The sharp deterioration of the environmental situation in the Republic of Kazakhstan, associated with human activity and the impact of harmful factors on the environment, affected the quality of food consumed by insufficient consumption of domestic fruit and vegetable products containing vitamins, minerals of an alkaline nature, carbohydrates, vegetable proteins, pectin substances and active fiber. The problem of improving the quality of growing and processing fruits and vegetables is one of the main tasks of the food independence of the Republic of Kazakhstan. Currently, the share of large vegetable farms in the Republic of Kazakhstan is only 10%. The volume of industrial processing of fruit and vegetable crops in Kazakhstan is insignificant. The demand for domestic fruit and vegetable products in the country is met only by 35-40%, most of it is imported from countries such as Russia, Kyrgyzstan, Uzbekistan and China. There is a need for the development of organic vegetable growing in Kazakhstan and the creation of new types of domestic fruit and vegetable products containing a sufficient amount of useful and active substances that can bind and remove toxic substances and radioactive elements from the human body. The purpose of the work is to improve the technology of fruit and vegetable semi-finished products with natural spicy and aromatic additives, to develop a multi-component recipe for vegetable mixtures and a method for producing quick-frozen vegetable mixtures with high quality indicators. These studies were aimed at studying the chemical composition and functional and technological properties of vegetables and spicy - aromatic plants for the content of biogenic compounds: carbohydrates, proteins, vitamins, essential oils, minerals and other substances. The structure of plant tissues was studied and the mass fraction of moisture, dry matter, fiber, mono - and disaccharides, pectin substances, vitamin C was determined, the formulation and production technology of Assorted vegetable mixtures were developed, and quality indicators were determined.

The article is devoted to the development of a technology for obtaining organic fertilizers from poultry waste based on biocatalytic processes. Currently, many poultry farms have become sources of environmental pollution, thereby causing serious environmental problems and economic and social damage. The problem of reliable protection of the natural environment from pollution by bird droppings is currently relevant. In the area of operation of large poultry farms, air pollution by microorganisms, dust, foul-smelling organic compounds, which are decomposition products of organic waste, as well as nitrogen, sulfur, and carbon oxides, is possible. Bird droppings contain acids, nitrogen, phosphorus and potassium, heavy metals. The content of nitrogen, phosphorus and potassium changes dramatically depending on the quantity and quality of the feed. Humic substances isolated from brown coal have a sufficiently high sorption activity and are used as cheap sorbents for solving a number of environmental problems in industry. These studies are aimed at minimizing the main disadvantage of the anaerobic digestion process, the low reaction rate, which leads to the need to create large-volume bioreactors. On the basis of the research carried out, a technology has been developed for obtaining organic fertilizers from poultry waste by the method of anaerobic fermentation of chicken manure with humidity at a temperature of 27 °C - 50 °C with the addition of sodium humate. The resulting fertilizer is intended for use in agricultural production, horticulture, floriculture, forestry, municipalities, in household plots in order to increase the yield and quality of crop production. For the developed technology, an application has been submitted for obtaining a Patent for the invention of the Republic of Kazakhstan «Method for producing organic fertilizers» (priority No. 2021-22818, dated July 13, 2021). The invention allows to significantly reduce the time of fermentation, to enrich the product with organic and mineral products contained in sodium humate, to convert the salts of heavy metals into an insoluble state, to improve the environmental friendliness of the method.

The development of extraction techniques of medical plants aims to maximize the bioactive compounds production. Тechnologies in this area of industry have not high enough еfficiency factor.

The article considers international experience in automating the system of land relations, aimed at improving the quality and reducing the time for the provision of services by state bodies to citizens and organizations, providing access to information databases, which positively affects the development of effective government decisions for the effective use of land resources, and also improves social welfare. In Kazakhstan, the transfer of land cadastral information to electronic media continues, and the automated information system of the land cadastre is being improved. The task of creating a unified mechanism for state cadastral registration of land plots according to uniform rules and technologies for all, identification and individualization of land plots and objects of immovable property firmly associated with them, for subsequent state registration of rights to land plots and transfer of information to the territorial bodies of the State Revenue Committee, remains relevant. To study the experience of developed countries in the provision of public services in the system of land relations through the development of official land information systems. The article used general scientific methods from general to concrete one, synthesis, theoretical generalization, induction, deduction, and system analysis. Based on the studied experience of developed countries, relevant conclusions and proposals were made: information technology is a useful tool and can help overcome bureaucracy, backwardness, isolation, monopolistic practices, and inefficiency in the public and private sectors; the use of state bodies for effective regulation of geographic information (GIS) systems that allow solving a wide range of tasks, as well as the use of modern information technologies, contributes to the transition of the activities of state bodies to a qualitatively new level of state control, which allows for full transparency of information about the land fund and objects real estate of the country, as well as its availability to the population. The provision of public services in the field of land relations using information and communication technologies reduces entry barriers and transaction costs in business, increases competition, and improves mechanisms in this area.

It is known that an increase in the volume of production in any sphere of production as a consequence increases the intensity of anthropogenic impact on the environment, including the atmosphere. This problem is especially typical for oil refineries. On the one hand, this is due to the complexity of oil refining processes and the release of various hydrocarbon compounds into the atmosphere during processing. Therefore, when implementing sustainable ecological and economic development in the Azerbaijani regions that are associated with oil refining, an increase in the volume of products should not create an increase in environmental impact. This problem is considered one of the factors directly affecting the economic situation of the enterprise, as well as creating certain environmental, social and economic problems for society as a whole. The purpose is to study the possibility of using the correlation-regression method in solving the problem of determining the presence of the decapling effect. The relationship between the volume of petroleum products produced and the amount of pollutants released into the atmosphere is random and is characterized by stochastic and statistical dependence. At the same time, on the basis of a mutual comparison of the methods of correlation and regression analysis and the method of production function, the effectiveness of correlation and regression analysis is determined. The methodological basis of the work was the scientific works of scientists-economists, mathematicians providing the definition of the decoupling effect at industrial enterprises. In the presented methodology, the obtained estimates of the performed in real time vary depending on the values of the set parameter. When developing the presented methodology, the STATISTIKA software package was used. This program was developed by StatSoft. Based on the obtained and experimentally verified data, the equation of linear regression dependence is determined. During the research, it was found that in some cases it is not possible to evaluate the statistical characteristics of a random variable or it is accompanied by serious errors. Therefore, when processing data, instead of mathematical expectations and variances, we used selective mathematical expectations and variances. The analysis of the ecological and economic situation of oil refineries based on correlation and regression analysis allows us to determine the presence of the decapling effect. The obtained correlation coefficient between the volume of production oil products and the volume of emissions into the atmosphere shows that there is no statistically significant relationship between these parameters. Thus, there is an achievement of the decoupling effect between the production of petroleum products and the volume of emissions of pollutants into the atmosphere.

The article examines the emergence and functioning of the Soviet institutions of power in Kazakhstan during the period of "war communism". On the basis of archival materials and published works, the author analyzes the activities of Soviets and revolutionary committees. The purpose of the article is to study the main trends and features of the development of local government in Kazakhstan in 1918-1921. The study is based on the principles of historical, scientific objectivity and systemic structural-functional analysis. For this reason, the author used such methods as the method of historical reconstruction for the reorganization of the administration of Soviet, party and other local bodies; the method of isolation for the study of local (regional) features in relation to local phenomena and processes in the energy sector; the method of typology, which made it possible to identify and describe different types of local authorities. The authors come to the conclusion that in 1918-1921, during the period of civil resistance, "war communism" and the beginning of the Chamber of Commerce and Industry, bodies of the new Soviet power appeared and operated in Kazakhstan. They are characterized as having an anti-democratic character; strict social orientation; alienation of indigenous peoples; immanent nature for creating conflict situations; choosing non-optimal ways and means of solving a problem situation; unification of party and state. As a result, an overgrown and clumsy class of party classification was formed, which was not provided for by the Constitution of the USSR.

On the territory of the Northern industrial zone of Pavlodar in the area of the industrial wastewater reservoir «Bylkyldak» in some areas of the earth there is soil contamination with mercury, exceeding the MPC for mercury (2.1 mg/kg) by 500 times. The total mass of mercury dispersed in the surface layer of soils is 2.8 tons. The mass of contaminated soil is approximately 208,000 tons. Pollution of the territory is historical. The purpose of the article is to determine the efficiency of chemical binding (immobilization) of mercury in the soil with the Japanese drug Denite® in real field conditions of the territory of mercury contamination in the Northern industrial zone of Pavlodar using an experimental study; to determine the stability of insoluble mercury compounds formed by the preparation at extreme winter and summer temperatures and seasonal fluctuations in open ground. Soil samples were taken for the study at 11 points in the centers of mercury pollution. Laboratory studies were carried out in an accredited analytical laboratory of the Testing Center of JSC Caustic. Soil samples were treated with Denite®, the preparations obtained were stabilized, and water extracts were prepared. The content of mercury in soils, extracts from them, and plants was determined by the atomic absorption method on a RA-915+ spectrometer equipped with RP-91 and RP-91S attachments. As a result of research, the effectiveness of Denite® in the chemical binding of mercury in the soil has been proven and its optimal dosages have been determined. As a result of the positive tests of the technology of chemical immobilization of mercury, the prospect of a practical solution to the issue of demercurization of mercury-contaminated soil on the territory of the Northern industrial zone appeared.

Main problem: the development of a new direction in the food industry – the so-called functional nutrition, which means the use of such products of natural origin, which, when systematically used, have a regulatory effect on the body as a whole or on its specific systems and organs, has been widely recognized all over the world: immunostimulants, biocorrectors for blood pressure, cholesterol levels, etc. When creating functional dairy products, ingredients of plant origin are increasingly included in recipes, which are sources of dietary fiber, vitamins and microelements, organic acids and other biologically active compounds, which can also serve as flavor fillers. Purpose: to develop a technology for the preparation of a fermented milk product with the addition of an extract from gourds. To do this, it was necessary: to select the amount (dose) of the yoghurt starter introduced into the prepared milk, and also to investigate the effect of temperature on the fermentation process of the drink; to investigate the amount (dose) of the vegetable filler introduced into the mixture and its effect on the organoleptic characteristics of the drink; to investigate the organoleptic properties of the drink with the melon culture extract added to it before fermentation and after fermentation; to investigate the effect of vegetable filler on the fermentation process; to investigate the effect of the dose of vegetable filler on the process of acid formation; conduct microbiological studies of milk and vegetable yogurt; to investigate the change in the acidity of milk and vegetable yogurt during storage; to investigate the effect of the freezing process on the chemical composition and biological value of the extract.
