Annotation: 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. In some cases, it reaches only 40-50 %. Therefore, development of new methods to effectively extract different compounds from plant material and their input into large-scale industry is of great importance. The goal is to determine an effective and suitable technology for extracting bioactive compounds from medical plant. This is a narrative review paper which focuses on different extraction methods of medical plant. To find relevant articles for this narrative review, 73 articles were reviewed. Of these, 14 irrelevant documents were discarded. This review analyses various extraction processes to guide the selection of suitable methods for various types of medical plants and applications. This is done by outlining traditional and modern methods of extraction techniques, exploring the importance of solvents for extraction, and comparing novel and alternative methods of extraction. In conclusion, based on the current knowledge, solvent extraction is the most common method for medical plants extraction. Enzymatic hydrolysis and supercritical extraction are advanced techniques with high yield of compounds. However, more research is needed for some modern extraction methods.

Annotation: Main problem: The development of the genetic potential of poultry, as well as the receipt of high-quality eggs for collection or further incubation, are possible only if rational and correct feeding of the broodstock and, more importantly, the young during its rearing period is observed. During this period, high-quality protein nutrition occupies an important place, which determines the level of productivity, stable growth, reproductive ability of the bird, as well as the state of health during the feeding period. Protein deficiency always remains an urgent problem for agricultural land, whose main activity is aimed at breeding dairy and meat animals. In this regard, research in the field of finding the use of non-traditional protein feed is of great need. If we summarize the modern achievements in the field of protein and aminoacid nutrition of poultry, we can find the most profitable way to obtain feed additives in industrial production. The studies, the results of which will be described in this article, are aimed at studying the possibility, experimental substantiation of the optimal dosage and the effectiveness of using the feed additive from crustaceans Artemia salina in the diets of chickens of the egg-meat direction of productivity [1]. Purpose: To study the possibility, experimental substantiation of the optimal dosage and the effectiveness of the use of the feed additive from crustaceans Artemia salina in the diet of chickens of the egg-meat direction of productivity. Methods: Analysis and generalization of theoretical information Results and their significance: This article presents the results of the analysis and generalization of theoretical material. The theoretical significance is determined by the fact that it is invested in scientific and practical problems related directly to solving urgent problems, increasing the efficiency, competitiveness and quality of domestic poultry products.

Annotation: 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.

Annotation: Singularly perturbed partial differential equations with small parameters with higher derivatives deserve special attention, which often arise in a variety of applied problems and are used in describing mathematical models of diffusion processes, absorption taking into account small diffusion, filtration of liquids in porous media, chemical kinetics, chromatography, heat and mass transfer, hydrodynamics and many other fields. It is necessary to consider the creation of an asymptotic classification of solutions of singularly perturbed equations using a well-known approach to solving the boundary value problem. In this case, the singular problem is understood as the problem of constructing the asymptotics of the solution of the Cauchy problem for a system of ordinary differential equations with a small parameter with a large derivative. The asymptotics of the solution in all cases is based on the last time interval or the construction of a boundary value problem for a system with a weak clot in an asymptotically large time interval. Purpose - to construct and substantiate the asymptotics of solving a singular initial problem for a system of two nonlinear ordinary differential equations with a small parameter; To date, a number of methods have been developed for constructing asymptotic expansions of solutions to various problems. This is the method of boundary functions developed in the works of A.B. Vasilyeva, M.I. Vishik, L.A. Lusternik, V.F. Butuzov; the regularization method of S. A. Lomov, methods of averaging, VKB, splicing of asymptotic decompositions of A.M. Ilyin and others. All the above methods allow us to obtain asymptotic expansions of solutions for wide classes of equations. At the same time, such singularly perturbed problems often arise, to which ready-made methods are not applicable or do not allow to obtain an effective result. Therefore, the development of methods for solving equations remains a very urgent problem. As a result of the study, an algorithm for constructing an asymptotic classification of the initial solution of the problem with a singular perturbation is given, and approaches to estimating the residual term are also shown.

Annotation: Main problem: Currently, there are various socio-economic and environmental problems in the development of rural regions, among the key ones: access to basic services, lack of transport connectivity, inadequate social, housing infrastructure, and others. Achieving sustainable development of the territory is one of the important priorities, which is of great importance for any state. Sustainable development is understood as harmonious development from the perspective of the economy, social sphere and ecology. At the same time, the sustainable development of socio-economic and natural systems is not possible if many factors and conditions are not taken into account that can directly affect the current state and long-term sustainability of their functioning and interference is not created on these processes within the framework of the implementation of various policies by the state. Purpose: In this regard, the purpose of this study is to identify and study the key factors that determine and contribute to the balanced development of rural regions of the country in the context of sustainable development goals and objectives. Methods: Empirical methods of economic cognition, methods of induction and deduction, synthesis, as well as logical methods were used in the framework of scientific research. Results and their significance: When classifying significant factors that influence the formation of sustainable rural development, it is necessary to take into account an essential feature of sustainable development – a harmonious combination of economic, social and environmental components of social development. Taking into account the logic of this study, based on the variety of factors contributing to the sustainable development of rural a reas, their systematization has been carried out.

Annotation: Currently, the problems of environmental safety are facing society. The industry develops every year. In this critical economic situation, the oil industry is a stimulant for the economic sector in Azerbaijan. The level of development of this industry is also relevant due to other reasons: sociological, technological and features of the economy of Azerbaijan. The production activity of oil processing, concentrating harmful substances and energy, is a source of man-made danger and pollution of the natural environment. The risk management process mainly consists of three stages - risk safety analysis, risk assessment, which is carried out in comparison of calculated and actual risk levels, the so-called acceptable risk levels and the adoption of appropriate regulations and management decisions. One of the factors that should be taken into account when assessing risk and safety is to determine the necessary costs. Since these costs are paid directly to the company, they try to minimize them as much as possible, which reduce the accuracy of risk assessment. One of the objectives of the study is to determine the optimal value of the necessary costs. It is established that the less reliable the method, the lower is the cost of its implementation. The methodological basis of the work was scientific works on these problems of scientists-economists, mathematicians on safety and risk assessment at industrial enterprises. When developing the presented methodology, computational algorithms developed by Dow Chemical were used. This company has collected a large volume of material on accident statistics, taking into account damages. Based on the obtained and experimentally verified data, a system of indices has been developed, an assessment of various indicators for qualitative and quantitative risk assessment of oil refineries. The analysis of the technogenic danger of oil refineries makes it possible to determine ecological and economic losses and choose rational possibilities of acceptable risk. The required costs, depending on the level of risk, are determined based on an increase in the accuracy of calculating the probability of occurrence of the cause of risks. The article examines the relationship between the expected level of risk and economic losses during oil refining in separate technological units, which allow determining the required level of risk and the expected economic damage.

Annotation: The securities market is the most important instrument for financing and developing the economy of any state, including Kazakhstan. The main problem is to attract investments for enterprises in all sectors of the economy, as well as to ensure that enterprises have access to cheaper equity than bank loans. Purpose to identify the main trends in the development of the domestic securities market, to assess the level of its profitability. The article emphasizes the role of the securities market as the most important mechanism for the redistribution of funds between sectors of the economy. The securities market, as an integral part of the financial market, is gaining especially growing importance in the economy of Kazakhstan, as well as in the economy of the entire world community. When writing the article, traditional methods (comparison, description, and measurement), general logical methods and research techniques (analysis, generalization, etc.) were used. The article discusses the main theoretical approaches to determining the essence of the analyzed concept, attempts are made to formulate the main problems in the securities market, presents the results of the analysis of data characterizing the current state of the stock market of Kazakhstan. In essence, the securities market is a macroeconomic regulator of the state, through which opportunities are created to attract foreign and domestic capital. Thus, the securities market as an effective tool for attracting capital contributes to solving socio-economic problems. The author notes that the main theories about the state of the stock market are characterized by a superficial approach, as evidenced by the fact that none of them considers the internal structure of the stock market, which is the main tool for determining the patterns of changes in the value of financial instruments. It should also be noted that the choice of theory depends entirely on the perception and opinion of the relevant analyst. Singling out one theory as the only and most acceptable one would be wrong.

Annotation: In the conditions of market uncertainty, the coronavirus pandemic, the absence of an officially articulated national idea, national interests and ideology in Kazakhstan, the problem of the lack of logically justified and coordinated coordinates of systemic thinking, an unambiguous paradigm of humanitarian thinking (analytical, pedagogical, managerial, economic, etc.) is becoming more and more clearly realized as the most important conditions for personal, civil and professional self-determination. The purpose is to substantiate the general logical coordinates and methods of reformatting the ambiguous humanitarian paradigm used in the activity. The study used various methods: the ontological principle of genetically meaningful logic, the method of transformation of concrete images of objects based on their abstract essence, the method of ascent from the abstract to the concrete, the speculative language of schematic images of thought and the language of methodological theory of activity. Logically justified universal abstract-concrete coordinates of universal motion are given. In relation to life and the world of activity, they can be concretized by coordinates: "standard of living – efficiency of activity", or "efficiency of activity – time", or "results – costs", or "quality – quantity", etc. The use of motion vectors in the logic of descent from the concrete to the abstract (NCA), ascent from the abstract to the concrete (AAC), as well as in their combination – logic CAC gives certainty to thinking. As an example, the scheme of the qualitative difference between educational (pre-professional) activities from professional ones using these methods and paired dialectical categories is given. The scheme and description of the functional model of the system object, considered as a rubicon of the transformation of educational activity into professional activity, are given. To reformat the indefinite, ambiguous paradigms of the humanities used in the activity into functional-logical, visible, constructive and unambiguous, it is recommended to use abstract-concrete coordinates, the methods given, the language of schematic images and the paradigm of the methodological theory of activity. As an example, the concept of a typical unit of activity development is given. A visible unambiguous paradigm is a necessary, but not sufficient prerequisite for adequate personal, civil and professional self-determination of a person in situations of high uncertainty. A sufficient prerequisite is the acquisition by subjects of appropriate reflexive-thinking abilities for self-determination, self-organization, self-regulation, etc.

Annotation: Main problem: Microbial-plant relationships, including epiphytic microflora, are the subject of attention of many scientists. Numerous works confirm the high interest of researchers and the relevance of studying this topic. Despite many years of research, some questions concerning the characteristics of the epiphytic microflora still remain open. It is already a well-known fact that the epiphytic microflora is directly related to the physiological development of the plant, including yield. This is due to the close interaction of the plant with the microorganisms living on its surface throughout the entire growing season. It is also proved that epiphytic microflora has the ability to change characteristics under the influence of environmental factors (temperature, humidity, soil contamination, sunlight, etc.). In this regard, the study of this topic is one of the important areas of biological and agricultural sciences and is of high importance. It should be noted that a significant role in the development of agriculture in the Republic of Kazakhstan and the Pavlodar region is played by representatives of vegetable crops, including tomatoes and potatoes belonging to the Solanaceae family, which indicates the high importance of the plants selected for the study. The combination of the above arguments determines the need to study the epiphytic microflora of plants and establish the regularities of its influence on the adaptive properties of the studied plants of the Solanaceae family, as well as on their productivity. In turn, the study of epiphytic microflora can also contribute to the search for new ways to increase the yield of plants and their resistance to various diseases. Purpose: The article is devoted to the study of the properties and characteristics of the epiphytic microflora of the surface of various organs of plants of the Solanaceae family (on the example of tomato and potato). The variability of the composition and number of epiphytic microorganisms in seasonal dynamics is shown. Methods: bacterioscopic method, fingerprint method, flushing method, Gram staining method. Results and their significance: The characteristics and properties of representatives of epiphytic microorganisms of aboveground (leaf, fruit, flower) and underground (potato fruit) plant organs were studied. The role of the influence of environmental factors on the variability of epiphytic microflora is determined on the example of plants Lycopersicon esculentum Mill. (common tomato) and Solanum tuberosum L. (tuberous nightshade). The differences in the microflora of different plant organs in different periods of vegetation are shown.
