This article is devoted to the development of designs for an experimental screw press for the production of safflower oil in small enterprises of the grain processing industry. A theoretical analysis is considered to develop the process of pressing oilseed material in a screw press. Using the methods of mathematical modeling, the problem for squeezing the liquid phase from a dispersed material is described and solved. And also a schematic diagram is given and the characteristics of the press equipment and the principle of its operation are given. The proposed method for the theoretical calculation of the pressing process makes it possible to determine the optimal parameters and carry out the extraction of safflower oil by pressing using the proposed design of the working body. Dependences (expressions) of the mathematical model are obtained, which make it possible to determine the optimal values with preliminary consideration of the necessary parameters when intensifying the pressing process.

This article is devoted to dairy and fermented milk products that have become relevant today. In our country and abroad, significant changes are taking place in the technology and technology of the production of fermented milk products, the product range is expanding. This article discusses the scientific work and research of foreign scientists, as well as new technologies have been developed with the study of the properties of the studied products of recent years. Analysis and generalization of literature sources have shown that many issues of technology development, increasing the nutritional and biological value of fermented milk products are insufficiently studied.

At the same time, positive trends have been taking place recently – the use of fermented milk products in the formulation with the addition of vegetable raw materials (vegetable, fruit) in fresh form, as well as canned (purees, jams, dry concentrates) provides fermented milk products with various flavor colors and an increased content of carbohydrates, vitamins and minerals. The use of vegetable, fruit and berry fillers in the production of fermented milk products ensures the expansion of the range and improvement of organoleptic indicators of the products.

In modern elementary particle physics, conducting actual experiments becomes more complicated due to the rise in cost and complexity of technologies, as well as long-term fundamental preparation for conducting such experiments. Since the processes occurring in elementary particle physics has a statistical nature, the simulation of such experiments is a multiple measurement of a set of random processes such as particle interactions and their passage through a detector. This problem can be solved by computer simulation of physical experiments by the Monte Carlo method. This paper presents the results of modeling an experiment on studying neutron radiation using the geant4 software package. It is shown that the simulation results correlate with the actual behavior of neutrons. These data show that this method can be used in modeling such experiments.

This article shows that various amounts of extract from raw rosehip (10, 15%)  are injected into the composition of a large-sized meat product. In the course of the study, the results of the influence of various amounts of rosehip extract from raw materials (10, 15%) on the organoleptic, physico-chemical parameters of a large-sized meat product were presented. The method of preparing large-sized meat products involves the use of a vegetable mixture, spices, water and heat treatment. At this stage of the study, we conducted an experiment to determine the optimal ratio of herbal supplements in the technology of a large-sized meat product. Large-piece meat products - only from pieces of meat, consisting of one or more large muscles, which are a single whole and are characterized by a heterogeneous technological value. The surface is smooth, without deep incisions in muscle tissue (no more than 10 mm), tendons and hard surface tissues are removed. Nutritional and biological value of meat. The nutritional value of meat depends on the ratio of the tissues that make up its composition. When determining the nutritional value, the first is determined by the content of biologically complete and quickly digestible proteins. The biological value will depend on the quality of the protein components.The coarse-grained meat product, which included a brine with 10% rosehip extract, and the coarse-grained meat product, which included a brine with 15% extract, had high humidity, soft consistency, and a pleasant smell characteristic of the smell of rosehip extract.

The article demonstrates the development of the electronic textbook "Cognition" on the Turbosite platform. The advantages and results of the study are given when using this electronic textbook in the process of teaching English. It was concluded that thanks to the colorful design, the presence of various forms of presentation of educational material, it allowed students of different ages to study the material much faster and better. The main difference between the electronic version of the textbook and the traditional paper version is in the open system of the first. If the information becomes outdated and needs to be updated, then the paper version of the textbook will have to be issued in a new edition, which will take more time and high financial costs. And in the electronic version, you can easily add, replace or delete information without much financial and time losses.

In this paper, we consider the possibility of using a binary steam turbine plant cycle in the heat supply systems of cities, in which the lower cycle is carried out by saturated  steam of a low-boiling working fluid, in this case freon-410. The advantage of this type of freon is that it is practically non-toxic, chemically stable, and maintains a constant temperature in phase transformations. In the area of high temperatures, water (steam) is taken as a working fluid, which has such advantages as accessibility and safety, and disadvantages are a limitedly low critical temperature and high heat capacity. The paper defines the thermal efficiency of the binary cycle and establishes its dependence on the thermal efficiency of the Carnot cycle.

In this paper, the efficiency of heating devices is considered. On the experimental installation "Automated heating system-03" modeling of operating conditions was carried out. It is considered how the temperature of the heat carrier of the heating system changes (water is traditionally used as the heat carrier) as it passes through the heating devices. The heaters are connected to each other in series, while temperatures are controlled: at the inlet to the first heater, at the outlet of the first heater and at the inlet to the second heater, at the outlet of the second heater. As a result, graphs were obtained that clearly demonstrate the change in the temperature of the coolant over time. As a result of mathematical processing, equations were obtained that describe the dependence of the heat output of heating devices on the duration of operation.

In this paper, we consider the possibility of using electric filters for cleaning flue gases from thermal power plants. Considering that most heat generating devices at the energy facilities of the Republic use solid fuel - coal, the issue of increasing the degree of flue gas purification is very important and relevant. The article provides a classification of electric filters according to the principle of operation, according to the methods of cleaning, according to the direction of movement of gases and according to the shape of the electrodes. The advantages of electrostatic precipitators are presented in detail. The paper presents the composition of Karazhyrinskoye coal and the initial data, including chemical and mechanical under burning, for which the calculation is carried out. There is an analysis of the composition of flue gases (emissions) of CHPP-1 of the city of Semey. The results of the studies carried out on the basis of CHPP-1 showed the degree of efficiency of using an electrostatic precipitator.

The features of the spatial distribution of the gross lead content and the forms of its compounds in the soils of the Karazhyra coal deposit, which is located in the East Kazakhstan region on the territory of the former Semipalatinsk nuclear test site, are investigated.

It was revealed that the average concentrations of lead in the soil of the deposit exceed the background values by 2.5 times, however, in relation to Clark, lead does not form significant anomalies in the soils in terms of intensity and contrast. The highest degree of heavy metal contamination was found in the northern part of the research object, which corresponds to the location of the on-board rock dump and coal loading ramp, as well as the wind rose. Minimal amounts of lead are concentrated in the soil in an easterly direction.

The maximum and minimum zones of accumulation of the chemical element in the lichen of Parmelia vagans growing in the technogenically polluted territory of the coal mine have been established. The average concentration of lead in lichen was 3.9 mg/kg, which exceeds the background level by 2.8 times. The calculated coefficient of biological absorption showed that lead, according to the ability of accumulation in lichen, according to the classification of A.N. Perelman, belongs to the elements of strong accumulation. A connection was found between the lead content in lichen and its accumulation in the soil cover of the studied object.
