Mathematical modeling of the results of experimental studies of the influence of the type and dose of cheese melting salt on the qualitative indicators of melted cheeses
Annotation:

The article is devoted to the mathematical modulation of a complex of experimental data obtained in the process of experimental studies of processed cheese products, processed by mathematical methods. The purpose of this study is to establish the type and amount of the melting salt that promotes the formation of the plastic structure of the processed cheese product. The analysis of scientific research in the field of food technologies showed that mathematical modeling is used in the following areas: clarification of the modes of technological processes, design of recipes and assessment of the quality of finished products, as well as forecasting the shelf life of new products when they are put into production. The most relevant in describing the processes of food production are models of multivariate variance-regression analysis using methods of mathematical planning of the experiment. The authors carried out mathematical modeling and established graphical dependencies characterizing the degree of influence of the regulated factors X1 and X2 on the controlled ones that determine the quality and safety of processed cheese products. It is important that the mathematical analysis of the graphical dependences of the rheological parameters on the adjustable factors indicates the reliability of the data obtained. It is concluded that an increase in the melting salt dose leads to an increase in the – limit shear stress, which reflects the nature and state of the consistency of the processed cheese product. The process of normalization of the controlled factors by the maximum value was carried out. Graphical dependencies were built and regression analysis was performed, the results of which allow an objective assessment of the degree of influence of the type and dose of the melting salt on the chemical and organoleptic characteristics of the test products. The authors have proven that the optimal efficiency of transforming the structure of the constituent components of the recipe into a plastic structure of a processed cheese product that is stable during storage is provided by a combination of adjustable factors X1 (Solva 85) and X2 (Solva 120) taken in a ratio of 1: 1, with a total amount of 1,2 mas.%. At the same time, the quality indicators of the experimental products are characterized by the following values of the controlled factors: У1 – 1280 Pa; У2 – 9 points, У3 – 9,301 (2,0-2,2109 colony forming units /g).

General characteristics and taxonomic composition of epiphytic microflora of plants
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.

Development of technology for a new cottage cheese product with fruit and berry fillers
Annotation:

Main problem: The unfavorable conditions in which a significant part of the population of our country lives (living in conditions of harmful, stressful, physical, chemical and radiation effects), an imbalance in nutrition dictate the need to create a variety of functional products enriched with pro– and prebiotic factors. In the science of nutrition, a functional direction has been developed - this is nutrition, which provides for the consumption of such products of natural origin, which, when used daily, have a regulating effect on the body as a whole, its certain systems, organs, providing a drug-free positive correction of their function. Compared with traditional types of dairy products with high organoleptic and commodity characteristics, produced on the basis of classical technological techniques, dairy products of the new generation should have increased nutritional and biological value. The article is devoted to the research and development of the technology of a new cottage cheese product - cottage cheese paste produced with the addition of lactulose concentrate and fruit and berry fillers. This article discusses the steady trend towards the use of fermented milk products with functional properties in the diet of modern humans. Purpose: Study and development of technology of thermized cottage cheese paste enriched with prebiotic lactulose and fruit and berry fillers. Methods: Analysis and generalization of theoretical information, organoleptic evaluation, physicochemical methods of analysis, microbiological methods of evaluation of cottage cheese paste, quality control of the finished product. Results and their significance: The positive role of prebiotic substances in the vital activity of the macroorganism was studied. It is not for nothing that academician Andrei Georgievich Khramtsov once called lactulose "a miracle made of milk." Lactulose, being a strong bifidogenic factor, allows stabilizing the microflora of the stomach. Lactulose activates the growth of bifidobacteria, which take root well in the intestine and ferment lactulose to form lactic acid. Lactic acid suppresses the development of pathogenic and putrefactive bacteria. As a result of the conducted studies, it was determined that the cottage cheese paste enriched with lactulose had high quality indicators and retained its consumer properties during the entire storage period. The introduction of lactulose into the recipe of cottage cheese paste does not reduce the nutritional advantages of the finished product.

Annotation:

The variety of species and forms of parasites of agricultural animals and the features of their life cycles are the basic foundation for the production of different types and medical forms of antiparasite medicine. In the treatment of the parasitic diseases of agricultural animals, one of the main factors is that the veterinary doctors have the knowledge on the mechanics, efficiency and the safety for humans and environment of the medicine being used. Taking into account high pathogenicity and resistance of parasitic organisms and their ability to adapt to effect of medicine, it is crucial to permanently monitor the efficiency of the applied anthelmintic drugs, including the new drugs offered by veterinary services. This article will describe the results of the research on pharmacodynamic and pharmacokinetic parameters of «Ivermectinum», «Ivermec», «Aversect-1», «Аvrsect-2», «Аivin» drugs and their methods of application with the consideration of terms of maintenance and immune status of cattle herds in Mayconyr village (Irtysh district, Pavlodar region). A comparative analysis of efficiency of the above mentioned drugs in dehelmintization and treatment of cattle was conducted with the results provided. The recommendations and the restrictions on use of the drugs were determined considering the farm condition. The experimental research of the aforementioned broad-spectrum drugs was conducted strictly following the rules of asepsis and instructions on application. The total number of replacement heifers subjected to the dehelmintization under the method of analogues is 150 units. Anthelmintic treatment was conducted two times a year - in springtime (March-April) before pasturage, and fall time (September-October) before confining the cattle in the stable. Coprological study on intestinal helminthes of the examined cattle was conducted in Irtysh RVL of the Pavlodar regional branch of RVE RVL VCaSC MA RK by ovoscopical, flotation and larvoscopical methods. There is a comparative analysis on the efficiency of avermectin group antiparasitic drugs applied twice a year for cattle dehelmintization. The recommendations on the use of the aforementioned drugs for dehelmentization and prevention of parasitic diseases are provided and the requirements for the use were determined.

Methods of teaching conversational skills, their advantages, disadvantages and overcoming language barriers and anxiety when learning a foreign language
Annotation:

Globalization is an integral part of our life. Therefore, today the relevance of learning foreign languages, in particular English, is beyond doubt, as interest in foreign culture, education, travel, life and work abroad increases. It is known that English is the most widespread international means of communication (including information technology and web space), for most of the population it is the native or state language. This is due to historical, political and geographical prerequisites, as well as socio-economic and cultural development. Proficiency in English opens up great prospects for those who know, but not every person chooses a linguistic direction of study when entering a higher educational institution. Mastering English is a laborious process. In universities of non-linguistic areas, one of the main problems for students is the so-called language anxiety and psychological barriers, especially for those students for whom English is not a core subject or direction of future activity. Overcoming language anxiety and psychological barriers continues to be an urgent issue in pedagogical psychology and the educational process of higher educational institutions. Therefore, the task of the teacher is to create such conditions in his classes so that the student has a desire to learn, develop himself and improve himself. It is necessary to form motivation for conversational skills through psychologically thought-out techniques and methods. The task of the teacher is to direct the student from a conniving and indifferent attitude to study to a conscious and positive attitude. To implement the above, the teacher needs to form the old motives and stimulate new, positive ones. The encouragement of positive manifestations of emotions should be supported, stimulated and helped to realize these emotions by the teacher in the educational process. For example, simple tasks, but at the same time fascinating, the manifestation of sincere emotions in the classroom by the teacher himself and his personal examples inspire students to pronounce their state of mind and experiences. Encouraging and highlighting the activity of students also helps to increase the motivation of learning, especially if they have creative ideas that differ from other fellow students. The purpose of the article is to describe the methods of teaching conversational skills, their advantages and disadvantages and to consider in detail the overcoming of language barriers when learning a foreign language. The methodological basis of the research was the works of such authors as: H.F. Makaev, O.S. Zorkina, V.P. Ipatova, L.V. Barinkova, E.V. Zarubina, E.I. Kaputskaya, E.I. Passov, E.G. Asimov, A.N. Shchukin and others. Critical analysis of scientific and methodological literature on the problem, study and generalization of positive experience of teachers; collection of empirical information, experiment, quantitative and qualitative data analysis. The results of the study can be used in the process of developing practical recommendations for psychological work with students in order to increase their motivation to learn a foreign language. In addition, these results can be used by teachers to correct and improve the effectiveness of the educational process.

Improving the means and methods for the prevention and treatment of postpartum paresis of cows
Annotation:

In modern conditions, the problem of the incidence of cows with high productivity in the postpartum period is relevant. It is these animals that are more susceptible to various diseases, primarily due to violations of the technology of keeping and feeding, weak body resistance, heavy loads during fruiting and milk production. It is known that as a result of various metabolic disorders, calving of cows in farms proceeds with various deviations. The lack of calcium in the blood due to hormonal disorders leads to hypocalcemia and paresis after calving, which is often the cause of death of animals. Therefore, the improvement of prevention schemes and treatment of puerperal paresis in cows is very relevant. Purpose of the article – Improvement of preventive and therapeutic measures for postpartum paresis in cows on the basis of the Tassu farm in Akmola district. The work was carried out under production conditions on a livestock farm in the Akmola region, in the farm "Tassu" in the spring and summer. The object of the study were black-motley cows with a pregnancy period of 250-260 days. 22 animals were selected in the experimental group, 12 animals in the control group. The average weight of animals is 567 ± 34.5 kg, age 5-6 years. The cows of the experimental group received injections of the drug Karsulen, which included: 2 % Cardus marianus D3, 1 % Sulfur D6 and 1 % Arsenycum album D6. Karsulen was administered to cows intramuscularly or subcutaneously at the rate of 1 ml per 100 kg of animal weight, the dose volume should not be less than 5 ml per animal. In the postpartum period, in the complex therapy of postpartum paresis in cows, Karsulen is used intramuscularly or subcutaneously 1-2 times a day. The use of the drug Karsulen with the composition: 1 % Cardus marianus D3, 1 % Sulfur D6 and 1 % Arsenycum album D6 has a regulatory effect on protein, carbohydrate, fat metabolism, restores impaired function of the gastrointestinal tract, liver and kidneys.

From the history of public administration in Kazakhstan during the period of "war communism"
Annotation:

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.

Family crises and ways to overcome them
Annotation:

The concept of resilience, the ability to withstand crises and adversities and recover from them, has valuable potential for research, intervention and preventive approaches aimed at strengthening the family. There are many paths to relationship resilience, varying depending on different forms of family, psychosocial problems, resources and constraints. Shared beliefs that promote alignment and cooperation are vital to overcoming adversity. Measures to increase the resilience of families are of timely importance to overcome the rapid social changes and uncertainties that families face today. According to research by sociologists and family consultants, each family goes through several stages of development, and the transition from one to another is usually accompanied by a crisis. It is generally believed that domestic difficulties lead to complications in family life, first of all. The purpose is to identify the types of problems and causes leading to crisis situations in marriage. In this regard, the methods such as analysis of literary sources on this topic, generalization, synthesis, psychological experiment, diagnosis of the psychology of family crisis by H.I. Olioirovia, T.A. Zinkevii-Kuzemkin, T.F. Velenta were used. The authors of the article come to the conclusion that stress is a part of life, and the slings and arrows of misfortune hit all families throughout their lives. The concept of family resilience confirms the reparative potential of all families and offers a valuable basis for research and clinical practice. Just as families face a variety of challenges, there are many ways to increase family resilience. By understanding key processes, clinicians can mobilize untapped resources, allowing families in distress to cope with difficulties more effectively and recover through their mutual support and cooperation. Therefore, it is necessary to understand the patterns of crisis situations and the socio-psychological causes of their occurrence.

Obtaining an effective biological instrument and method of reproducing lumpy skin disease
Annotation:

The production of vaccine preparations before release requires standardization of their immunobiological parameters, especially safety and immunogenic efficacy. An indicator of the immunogenic effectiveness of the lumpy skin disease vaccine is the resistance of vaccinated cattle against the virulent virus. However, according to preliminary studies, the virulent control virus did not always cause clinical disease with characteristic symptoms when infected subcutaneously. The purpose is to develop a biological model in the form of a complex consisting of a pathogenic virus, a method of infection and a susceptible animal to assess the immunogenicity of a lumpy skin disease vaccine. Local cattle, intact from lumpy dermatitis, were used to reproduce lumpy dermatitis and develop the causative agent of the disease. As the initial infectious virus, we used a 20 % tissue suspension of nodules (skin nodules) obtained from cattle that fell ill with lumpy dermatitis in the field in the Atyrau region in 2016. As a viral mass to control immunogenicity, a 20 % suspension of skin nodules and edematous skin tissue at the site of the pathogen injection, obtained after the “refreshment” of the virus in animals, were used. The disease was reproduced by infection with the test suspension of the virus intradermally, subcutaneously, intravenously at a dose of 0.5 cm3 and titration on the skin of the animal. The effectiveness of the biological model was assessed by morbidity, severity of the course and severity of the manifestation of the disease. During primary intradermal infection with a field isolate of the virus, the disease manifested itself in one of three animals in the form of hyperthermia, depression, lacrimation, and the appearance of several nodular nodules in the skin of animals. The refreshed tissue virus caused clinical disease both in subcutaneous, intradermal and intravenous infection. But the clinical signs of the disease were more pronounced with intradermal inoculation of the virus, and with intravenous inoculation, it manifested itself in a more severe form with a fatal outcome. Inoculation of the virus intradermally into different areas of the skin led to the development of an independent skin lesion in each infected point in the form of painful edema, followed by necrosis, the size and intensity of which depended on the dose of the injected virus. This development of skin pathology made it possible to work out a method for determining the virus titer in vivo. The tissue virus obtained from the edematous tissue at the site of the pathogen injection was guaranteed to cause clinical disease in cattle during intradermal inoculation and made it possible to evaluate the immunogenic efficacy of the produced batches of vaccine against lumpy dermatitis.

Development of a new type of curd mass using a vegetable protein-containing component
Annotation:

It is known that the nutritional value of proteins is primarily characterized by the composition of essential amino acids and is determined by their accessibility. Not just proteins are necessary for the good functioning of the human body, but a certain amount of essential amino acids. Since the lack or absence of any of them causes serious health problems. The problem of protein malnutrition is global for many reasons and to solve it, it’s necessary to study the prospects for the possible use of non-traditional sources of dietary protein, namely vegetable protein. Considering this, the article presents the results of studies conducted over several years, the objects of which were dairy and vegetable products and protein hydrolyzate from chickpea flour. At the same time, the possibility of its use as a filler of plant origin to improve the physicochemical and structural-mechanical properties of a new type of finished product was determined. The purpose of these studies is to develop a recipe and determine the technological stages of production of a new type of product of dairy and vegetable origin, which has a functional focus, in which vegetable products are used together with dairy components. It should be noted that when selecting components, preference is given to raw materials grown in the local region. When developing the recipe, the optimal amount of chickpea protein hydrolyzate to be added was determined, which makes it possible to give the finished product not only attractive commercial characteristics, which the modern consumer primarily pays attention to, but also to obtain such product properties that will help strengthen the immune system and the resistance of the human body to adverse conditions environment, what is especially important for the younger generation. When developing the technology of a new dairy-vegetable curd mass, the optimal modes of each technological operation and the stage at which it is most expedient to apply a vegetable component are determined. Launching the developed product into production, the manufacturer will not face the problem of the lack of the necessary equipment and its expensive acquisition, since the production organized according to the proposed technology is maximally adapted to the equipment available at enterprises engaged in the production of cottage cheese and curd products.

Promising directions in the use of retort packaging for the production of canned food products in Kazakhstan
Annotation:

The article is devoted to the study of the main types of retort packaging, as well as polymer and combined materials used for its manufacture. The authors have compiled a classification of retort packaging presented on the modern market, investigated the technological properties of packaging materials, and also determined the requirements for modern retort packaging: resistance to sterilization at a temperature of at least 120°C, steam and moisture resistance, chemical inertia to canned products, tightness, low gas permeability. It has been established that in order to give the retort packaging the required properties, it is made of multilayer polymer or combined materials, each of the layers of which performs certain functions. It is determined that due to the barrier properties of polymer and combined materials with respect to oxygen, retort packaging provides shelf life of canned products up to 5 years, which allows the use of retort packaging made of polymer and combined materials as an alternative to glass and metal packaging. In experimental studies, the composition of the outer layers of modern retort packaging was analyzed and it was concluded that polypropylene or polyethylene terephthalate are most often used, since these polymer materials are thermally and chemically resistant, vapor- and moisture-proof. It is established that materials that are barriers to gases are used as the middle layer – aluminum foil, metallized films, ethylene vinyl alcohol, polyamide. It is proved that polymer co-extrusion, multilayer injection molding or lamination is used for the manufacture of such materials and packaging. The data obtained indicate the high barrier properties of combined packaging materials, therefore, the thermal and chemical stability of the polymer and combined materials used makes it possible to use retort packaging for packing almost all groups of canned products.

Diagnostics of leading coping strategies of students
Annotation:

The article highlights the problem of coping behavior of students in stressful situations of the educational process. Purpose of the article - determination of the dominant productive and non-productive strategies of coping behavior among undergraduate students. While doing research the following methods were used: Coping with Stress Questionnaire (COPE) by K. Carver, M. Scheier and J. Weintraub, adapted by E.I. Rasskazova, T.O. Gordeeva and E.N. Aspen. Fourth-year students show significant variability in the choice of methods of coping behavior. This means they have a wider range of coping strategies. At the same time, first-year students do not have a diverse enough range of coping strategies. This may be due to their less experience and unfamiliarity with various coping techniques. Significant differences were found in the activity of using the effective strategy “Finding a solution to a problem” among students at different stages of training. This suggests that fourth-year students are more prone to problem-oriented coping, while first-year students prefer emotionally oriented coping with exam stress. As a result of the study, it was determined that the most common methods of coping behavior among students are the strategies “Accepting responsibility” and “Planning a solution to the problem.” This means that most students prefer active and mindful approaches to coping with difficulties. It has been proven that the relationship between methods of coping behavior and anxiety of students is different in all courses of study. This may be due to varying levels of experience, degree of curriculum difficulty, and other factors that influence perception and coping with stressful situations. These results highlight the importance of developing a variety of coping strategies in first-year students, as well as the need to support and train fourth-year students in using effective coping strategies.
