Biotechnological approaches in making new meat products
Annotation:

This paper presents a biotechnological approach of making a meat product in order to create a new domestic product. As the result of the study, prescription composition of the meat product with a cereal component was developed. Components comprise raw materials of domestic production, which allows to increase the level of nutritional balance of the product. The prescription composition includes secondary raw materials, and that allows manufacturers of processing industries to use non-waste production. This characteristic has been achieved due to the know-how. Secondary raw materials have nutritional value, but because of its features (coarse fibers) they are poorly digest by the body. The developed know-how ensures that these fibers are transformed into easily digestible form, giving the product special characteristics, which are described based on the results of nutritional value of the newly developed type of product. The developed new product allows to expand the range of meat products on the market.

Influence of ultrasonic treatment on the efficiency of biogas production
Annotation:

This paper presents the results of the influence of ultrasonic treatment in the cofermentation of the cattle manure mixture (cattle) with the leaven from the rumen of ruminants on the process of biogas production. Anaerobic digestion was carried out in matinence periodic operation at the mesophilic temperature of 38 C ̊. As a substrate, a mixture with a content of 70 % cattle manure and 10 % leaven from rumen of ruminants was used. Treatment with ultrasound of the mixture was carried out at an intensity of 10 W/cm2 and an amount of input energy of 9350 kJ/kg of dry matter (DM), which completely eliminated the processes of stratification and sedimentation. Decomposition of organic matter (OM) in the periodic regime with the enzyme and ultrasound treatment occurred within 8 days, the usual substrate during this time OM decomposed 3.0 times less (only 14 %). The process of fermentation of methane in continuous and periodic modes treated with ultrasound, as at other temperatures, was stable, as can be judged by the values of volatile fatty acids (VFA) Volatile fatty acids (VFAs), alkalinity, pH, and biogas. The energetical efficiency of methane fermentation is estimated by comparing the volume of fuel (biogas) and heat consumption for technological needs. As shown by the comparison of efficiency of different regime, the largest amount of commercial energy in the form of biogas was obtained in the mode of joint fermentation of a mixture of cattle manure (cattle) with a ferment from the rumen of ruminants treated with ultrasound – 3 times more than without treatment (space).

Organization of activities for the treatment and disposal of industrial waste at the landfill
Annotation:

Environmental protection measures are based, among other things, on the rationalization of the organization of the production waste management process. Population growth and the race to industrialize pose a serious threat to the ecosystem. Currently, the average global waste generation per capita is 494 kg / year. A large number of industrial enterprises operate on the territory of Kazakhstan. The range of manufactured products is very wide: household items, transport, building materials, equipment and much more. Each type of production is inevitably a source of a large amount of industrial waste, annually at the enterprises of Kazakhstan up to 600 million tons of waste are generated, three percent of which are recycled. On the territory of Pavlodar region there are enterprises in the field of metallurgy, mechanical engineering, chemical industry, construction industry enterprises, light industry, about a hundred in total. In this connection, the problem of treatment and disposal of industrial waste in Pavlodar region is very relevant. The article discusses the system of waste management in order to reduce their impact on the environment, activities for the disposal, transportation, disposal of waste, as well as their disposal at the industrial waste landfill in Pavlodar. The landfill in question is intended for the reception, temporary storage and disposal of non-hazardous solid industrial waste of the «green» level: waste and scrap of chromium, cadmium, aluminum, copper, lead, zinc, manganese, plastic waste, polyethylene, abrasive, rubber waste, ash and ash and slag waste; and also «amber»: waste containing mercury, arsenic, lead, waste batteries, phosphoric slags, waste oils, oil sludge. The scheme of organizing waste storage works is considered. The volume of accepted and recycled waste, as well as those placed at the landfill and used for their own needs, was analyzed, including construction waste, waste sleepers, ash and slag and abrasive scrap. The solution to the problem of industrial waste disposal is associated with the need for innovation and the introduction of new technologies and equipment.

On the question of forms and types of property rights in civil law
Annotation:

The right of ownership, like property itself, occupies one of the mainplaces in public life. Statutory regulation of property relations in the Republic of Kazakhstan existed throughout the entire period of statehood formation. Today, property relations are regulated by the norms of various branches of law. But civil law regulation occupies one of the most important places in the system of regulatory regulation. This article deals with a comprehensive analysis of the main legal concepts, such as property, owner, subject of property rights, as well as forms and types of property, the grounds for the emergence and termination of property rights and ways to protect and protect the absolute right of the owner. A certain thing may belong to several persons as common property. In this case, the right of ownership is distributed among several owners (co-owners). The totality of legal norms on common property forms the institution of common property law. The purpose of this work is a comprehensive analysis of the main legal concepts, such as property, owner and subject of property rights, as well as forms and types of property, the basis for the emergence and termination of property rights and the definition of ways to protect and protect the absolute right of the owner. The means of achieving this goal is the study of the works of Kazakh legal scholars, the study of the analysis of practical materials. The article uses the following methods: comparative-legal, system-structural, formal-logical, as well as the method of system analysis. The legislation of Kazakhstan provides for two subjects of State property that have the right to act on their own behalf: the Republic of Kazakhstan as a whole (in respect of property constituting republican property) and the administrative – territorial unit (in respect of property constituting municipal property). That is, in civil circulation, data are carriers of state property rights. Depending on the tasks performed, the State exercises the powers of the owner on behalf of one of the specified entities. The Republic of Kazakhstan and the administrative-territorial unit are not legal entities. However, unless otherwise provided by legislative acts, they are subject to the rules governing the participation of legal entities in relations regulated by civil law. The state and administrative-territorial unit, as special subjects, have all the rights ofsubjects of civil legal relations and are limited in legal personality only by the current legislation.

Features of teaching physics in English in secondary school
Annotation:

This article reveals the essence of teaching the disciplines of the natural science cycle in English in high school. When preparing for the lesson, there is a need for careful selection of educational material, the teacher thinks out a specific algorithm for working with the text in a foreign language using subject terminology, while not forgetting the basic grammatical and syntactic models characteristic of the English language. In such a language environment, foreign speakers actively acquire solid knowledge, eliminating language difficulties in professionally-oriented lessons. Given this problem, we decided to create a methodological guide for teachers, which will contain tasks for formative assessment in physics lessons in English. Its lexical and grammatical material meets the requirements for mastering the English language (B1) in educational and cognitive activities. The presented progress tests also meet all the requirements of the corresponding stage of training of non-native speakers and help to consolidate the skills of professionally oriented communication. The purpose is to reveal some principles that should be taken into account when preparing assignments for physics lessons in English, as well as to provide a methodological guide for teachers. This article shows several principles that are most effective when conducting lessons. All the data of the article was confirmed by a computer survey of students, the answers were analyzed and collected for publication. Given the results we have presented, secondary school teachers can improve the quality of the material provided, as well as spend less time preparing for lessons. Physics is one of the fundamental sciences that can combine both the subject content and the language component. Here we present various methods of subject-language integration to improve communication skills. Thus, the preparation and conduct of physics lessons in English requires a strict and careful selection of educational material and takes into account the educational profile of secondary school students.

Development of a technology for producing organic fertilizers based on catalytic processes
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.

Features of voluntary refusal depending on the construction of the corpus delicti
Annotation:

In recent years, the Republic of Kazakhstan has maintained an ambiguous criminal situation, and there is an increase in certain types of crimes, against the background of the overall positive dynamics of decline. Special attention of criminologists has recently been attracted to the study of crimes in the family and household sphere, and crimes committed in the sphere of religious and spiritual relations, since both of these types are showing increasing prevalence. Therefore, considering such an important institution as a «voluntary refusal», it would be advisable to consider them from the perspective of the offenses we have named, especially since countering them is one of the main directions of state criminal policy. In general, the study of the institution of voluntary refusal to commit an offense is based not only on coercive measures, but also on incentive measures, which means the opportunity to correct the behavior of the offender until the end of the illegal act. The purpose of this scientific article is to study the features of voluntary refusal to commit a criminal offense in crimes committed in the sphere of religious, spiritual and family-household relations, taking into account practice and making recommendations for improving regulations of a criminal nature. The leading methodological tools of the scientific article are dialectical, phenomenological, synergetic and systematic approaches of scientific cognition. Before proceeding to the analysis of the concept of voluntary refusal, it should be noted that the norms about it are far from perfect. There is no unambiguous understanding of the signs of voluntary refusal among scientists, which complicates law enforcement practice. One of the most important tasks of any scientific research is the development of scientific concepts. The consolidation of such concepts in legislation is an effective way to establish a uniform understanding of the norms, a clear idea of their content and, as a result, an increase in the effectiveness of the impact of criminal law in the process of legal regulation. However, these concepts themselves do not reflect reality like contemplation or representation, they are closer to the essence of the phenomenon. The article concludes that the essential features of the concept itself somewhat narrow the objective reality. But, at the same time, the correct identification of the main features in the concept is an important task of scientific research.
