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).

Among many environmental conditions that affect a person, the most important factor is nutrition. Today, there is no doubt that there is a direct link between nutrition, health and disease. Proper nutrition ensures normal growth and development of a person, contributes to the prevention of diseases, has a positive impact on life expectancy and creates conditions for adaptation to the environment. A very actual topic for public catering in the Republic of Kazakhstan, namely for fast food companies, is the development of new recipes and culinary products from relatively inexpensive vegetable raw materials, as well as qualitatively new food products with a purposefully changed chemical composition. One of the main ways of solving problems of expanding the production of products for quick service, as well as products for dietary and therapeutic and preventive nutrition is the use of sprouted grains and beans. In this article, poly-grain mixtures of sprouted wheat and extruded soy beans in different ratios are studied and considered. Poly-grain mixtures developed by us are balanced in nutrients, vitamins and amino acids. The research was carried out on the basis of the accredited testing laboratory of RUBICOM enterprise LLP and the scientific laboratory of the Innovative Eurasian University. The purpose of this work is to study a promising method for increasing the nutritional value of grain mixtures by extruding them at different temperature conditions. To achieve this goal, the following tasks were planned: – to study the grain of soy beans and sprouted wheat on the organolepti c characteristics and chemical composition of the poly-grain mixture; – examine the chemical composition of the poly-grain mixture before extrusion; – choose the optimal mode of the extrusion process; – study and analyze the chemical composition of poly-grain extruded mixture; It should be noted that we have developed for the first time the optimal technological mode of extrusion of poly-grain mixture from sprouted wheat and soy beans, and the physical and chemical composition of the poly-grain mixture was studied. The results of the research presented in this paper are the basis for the development of recipes and technologies for fast food products. The reliability and validity of scientific statements is confirmed by the choice of modern methods of chemical composition analysis.

Main problem: Presence of acidic chemicals such as carbon dioxide and hydrogen sulphide, composition of production fluids triggers corrosion. Corrosion in oil and gas industry leads to deterioration of equipment since most of equipment is made of metal alloys. Application of inhibitors is one of the corrosion mitigation methods that needs to be controlled because it is important to identify optimal concentration of the chemicals in production fluids.Residual chemical analysis plays an important rolein identifying the appropriate dosage of corrosion inhibitors and its correction. It is imperative to find the most optimal concentration of amines due to the fact that both overdose and underdose could lead to equipment deterioration. The chemical analysis is hindered by complexity of mixtures that are applied in petroleum industry. Purpose: The main purpose of this article is to find out the most effective method of residual chemical analysis for inhibitors used against sweet and sour corrosion by studying and analyzing corresponding literature review. The analysis should be carried out with robust, sensitive, and accurate instrumentation. Methods :Theoretical study of composition and mechanism of amines used in oil and gas industry as corrosion inhibitors and selection of appropriate instrumental analytical techniques for the residual analysis. Results and their importance: After careful studying and consideration of modern instrumental analytical techniques the most optimal and efficient method in terms of robustness, time saving and cost was selected. Ion chromatography is an adequate method to carry out residual chemical analysis for amines that are used as inhibitors in oil and gas industry to prevent sweet and sour corrosion.

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.

Combustion engines operate over a wide range of power and speed. To the greatest extent, this applies to automotive and tractor engines and diesel engines operating at fractional and idle loads for a significant part of the operating time. When designing engines, the choice of their main design and layout parameters is carried out in a comprehensive manner, taking into account the provision of the required power and efficiency in the modes of maximum torque and rated power. However, ensuring the economical operation of modern highly accelerated diesel engines at low loads and idling causes a whole range of problems related mainly to the organization of effective mixture formation and fuel burnout, as well as to ensuring stable fuel supply. Thus, the cycle dose of injected fuel in idle mode is 8–12 times less than the cycle dose in nominal mode, which determines increased requirements for fuel equipment and difficulties in ensuring high-quality mixture formation. At the same time, diesel engines operate in idle mode up to 50 % of the total operating time, consuming up to 15–20% of the fuel. For truck engines, the relative idle time is approximately 20–25 %. Thus, the development of measures to improve the efficiency of diesel engines at idle is relevant. The purpose is to perform a numerical analysis of the effect of switching off cycles in diesel engines for autotractor and diesel locomotive purposes on the working processes in the cylinder and the indicator parameters of the cycle in idle modes. When writing the article, traditional methods (comparison, description, and measurement), generallogical methods and research techniques (analysis, generalization, etc.) were used. A numerical analysis of the operating cycle of a diesel engine equipped with a cycle shutdown system was performed. The relationship between changes in fuel injection characteristics when cycles are turned off with indicator indicators of the engine operating cycle in idle load modes is disclosed. It has been established that the expediency of switching off cycles in a specific engine operation mode is determined primarily by the features of the injection, carburetion and fuel burnout processes.

This article presents the concept of a controlled landing of spent launch vehicles with liquid rocket engines (LRE) in the expected zones of damage to the ecosystems of the area while maintaining the energy-optimal launch scenario of the launch vehicle. Purpose of the article - development of effective technologies for reducing the anthropogenic impact during launches of promising rockets from the Baikonur Cosmodrome based on theoretical and experimental studies of innovative technologies: reducing the area of impact of parts from launch vehicles; fire and explosion safety, no danger of rocket launchers; controlled descent of used first stages; To solve the problem, it is proposed to create an additional IASM, which will be included in the environmental management system of the Baikonur Cosmodrome. Possible design solutions are proposed based on the evaporation of untreated liquid waste from the tanks of separated parts, their fire and explosion safety, and the use of the obtained vapor-gas mixtures for controlled unloading of separated parts while moving along the landing trajectory to the optimal area. The authors of the article have developed evaluation criteria that characterize the main environmental indicators of the studied areas: fire hazard, soil cover and impact on vegetation are studied for inclusion in the IASM. There are objective requirements and basic rules for the creation of HIASM, which is an integral part of the environmental management system of the cosmodrome.
