The intensification of animal husbandry is accompanied by an increase in demand for high-quality compound feed, which largely determines the level of development and economics of animal husbandry, especially industrial, specialized livestock farms. Reducing feed costs is one of the key challenges. Its solution is impossible without the rational use of grain and other raw materials, the introduction of modern innovative technologies and equipment at feed mills. Barothermal treatment of the grain mixture in the expander reduces bacterial contamination, completely destroys coliform bacteria, E. coli, mold fungi and salmonella. The technology for the production of expanded feed for broiler chickens was developed in the course of the work. Broiler chickens of the Smena 7 cross were used as the object of the study. It was found that the chicken palatability of the expanded compound feed developed with the help of the optimization program "Korm Optima Expert" improved and at the age of 28 days their live weight increased by 2.5–3 times in groups, chickens that received grits from granular expandate having the highest indicator (915 g). At the end of the experiment 42-days old chickens of the control group had a live weight of 2246 g, and the chickens that received granulated expandate - 2574 g. The average daily gain in live weight of chickens was 66.4 g, which is 7.9% higher than in the control group. The results of the control slaughter of chickens showed an increased yield of meat in chickens treated with expanded pellets (69.5%) compared to the control (67.6%). The best indicators of the productivity of broiler chickens of the Smena 7 cross were obtained when feeding compound feed in the form of grains from granulated expandate in the first period of cultivation and granulated expandate in the second period of cultivation.

The article is devoted to the development of a mathematical regression model of the beet pulp pressing process carried out on on a deep press extruder. The following parameters of beet pulp pressing were taken as initial ones: initial moisture content (before the extruder) and final moisture content (after the extruder); sugar content in the pulp before and after pressing; sugar content in the pulp; beet chips length before and after pressing; total biological contamination of sugar beet pulp; pulp acidity before and after pressing; acidity of the granulated pulp. The Fuzzy Logic Toolbox module included in the MatLab package is used to implement the proposed technique. The Surfase Viewer module is used to present the simulation results in a graphical form. Such studies were previously carried out with the CurveExpert 1.3 application package. The resulting equations adequately describe the change in the sugar content in the pulp and its nutritional value depending on the pulp acidity and moisture content, as well as the length of the sugar beet chips. The significance of the influence of each of the main technological parameters (acidity and moisture content of the beet pulp, the length of the beet chips) on the amount of sugar in the pulp and its nutritional value was determined in the work. The resulting quadratic dependences having sufficiently high coefficients R2, adequately describe the process of beet pulp pressing in a deep press extruder with an assessment of the influence of variable parameters on the content of residual sugar and feed units in beet pulp. The data obtained make it possible to objectively evaluate the work of a deep-pressing exstruder and justify the kinematic mode of the screws rotation, which allows minimizing the cost of finished products.

The article provides a solution to the problem of studying the characteristics of resource efficiency for a given time interval in the form of solving an optimization problem (using dynamic programming methods and the method of recurrent Bellman equations. A multistep search for a solution was carried out for a given period of planning production activities. Boundary requirements were met in different ways due to the multivariate management decisions. The features of the optimization model were considered. The solution of the multistep problem is reduced to the sequential solution of several one-step optimization problems. The function of changes in resource efficiency in lean manufacturing technologies was set for the planning period. Changes in technologies for the capability involved demonstrate how resource efficiency changes with the observation time. It is noted thaqt the experience accumulation of experts and participants in the production process in the implementation of innovative approaches is of great importance for reducing all types of losses. It was revealed that one of the crucial parameters in a multi-criteria system is the preservation of efficient operation in the subsystem associated with intelligent decision support. The optimal amounts of costs have been determined. Their assessment was carried out to allow for the fact that when solving optimization problems, it is necessary to take into account such criteria for which the values take extrema. Assuming a successful solution of the optimization problem posed and analyzing the results obtained when dividing the multistep decision into three one-step ones, we received S-shaped functions with a function value equal to 6.8%

Locusts are insect species that can form migratory swarms, causing widespread destruction of crops and pastures, with significant impacts on food security. This article assesses the potential for beneficial use of locust swarms. Of the 21 known locust species, about ten species have traditionally been consumed by humans or fed to animals for thousands of years in 65 countries. Their nutritional composition is comparable to that of regular meat. However, insecticide residues, microbial contaminants and allergens can jeopardize the safety of their use. Several countries have developed regulations for edible insects, including locusts. In this article, prototypes of acrides were obtained and their chemical composition was determined - the content of crude protein, dry matter, crude fat, crude fiber, minerals, and the amino acid composition was determined. All studies were carried out according to generally accepted methods, based on the results of the studies, conclusions were drawn and possible methods of using acrides are described - locusts are rich in protein; minerals such as calcium, iron and zinc; a number of vitamins; useful fatty acids; in addition, the quantitative content of amino acids in locusts is higher than in meat products of slaughter. Safe and effective collection of locusts can help preserve agricultural land, as well as provide material as feed for animals and fish, and rearing locusts under incubation conditions can facilitate their use in food products in order to enrich them with protein or replace part of the raw materials.

The article discusses the features a distance learning system (LMS) organization of an educational institution, reflects modern approaches to the implementation of management decisions in educational organizations. Among the main advantages of using the LMS are free access to the training course, the adaptability and flexibility of the educational trajectory, the relevance of training, minimization of costs, simplified access to training materials for people with disabilities, synchronous and asynchronous educational process, depending on the current needs of the educational institution. The relevance of the information tools used and the reduction of various kinds of costs (labor resources, time costs) during their implementation are emphasized. Particular attention is paid to issues of a financial nature, including the rationale for choosing a platform for the implementation of LMS based on commercial, free access or a system developed by its own resources. It is noted that the use of the SCORM, Tin Can and similar formats in the development of their own LMS may fade into the background if an educational institution has its own standards for electronic documents of open formats, such as XML. The need to build a quality control system for the implementation of the educational process in the development of your own LMS is shown. The distinguishing features are the possibility of generating multi-level reports and the formation of learning statistics, as well as the possibility of analytics, depending on the changing needs of an educational institution for monitoring and managing the educational process in a remote mode. It is noted that individually developed LMS, in contrast to open and commercial ones, have the ability to add their modules for the analysis of statistics. The article provides data on the effectiveness of using this tool for all target groups (faculty, students, administrative staff, legal representatives of students) and their impact on the overall organization of the management process in the system of higher and secondary vocational education.

The phenomenon of social responsibility is gradually penetrating the insurance business. He himself is also deeply socially significant. At the same time, the practices of participation of insurers in events and programs for the whole society, and not only for recipients of insurance services, are of particular interest. As a result of the study, a databank was formed that characterizes the participation of Russian insurance companies in socially oriented projects. It gives an idea of the scale of the supported initiatives, their focus and forms of implementation. The main forms of social interaction of insurance organizations at the municipal, regional and national levels were established. It has been proved that most of them can be considered as a full-fledged instrument of the social protection system of the population. The emphasis was made on the possibility of attracting their clients by insurance companies to participate in charity events. Such experience is a good example of social contribution, not only ensuring the implementation of social function and client participation, but also increasing the level of social responsibility of those who are initially considered exclusively in the role of recipients of insurance services. It was concluded that there is a relative diversity of initiatives supported by insurers, but at the same time, the involvement of representatives of the insurance community in social projects is extremely low. The main social tasks are presented, in the solution of which the resources of insurance organizations are currently involved.)

Contemporary market of food of animal origin and its substitutes, i.e. dairy alternatives offers a range of non-alcohol beverages of plant origin (plant “milk”) of different level of particles’ dispersion. At Russian food market dairy alternative beverages are mostly cereal and food products by well-known brands. Application of alternative types of bean crops (green beans and haricot) in production of non-alcohol beverages of plant origin or synthetic products should be proven not only with consideration of their biological activity and their toxicity as well. The article deals with the results of comparative analysis of nutritional value and the evaluation stage of the basic toxicity of natural compositions of plant dispersion of germinated grains of bean varieties bred at Bashkir Research Institute of Agriculture and Omsk State Agrarian University in in vitro conditions. To estimate the level of toxicity and biological activity of natural compositions of plant dispersion of germinated bean grain of varieties Chishminskiy 95, Chishminskiy 229, Pamyati Khangildina, and haricot of varieties Omichka and Lukerya the most popular method for OZBlue - matter detection was used, i.e. the test on human civilized cell cultures HEK 293. It has been found out that plan dispersion of these varieties do not show the visible toxicity level in the interval of the concentrations under research, what gives a possibility to use them for targeted production.

It has been found out that plan dispersion of these varieties do not show the visible toxicity level in the interval of the concentrations under research, what gives a possibility to use them for targeted production.","PeriodicalId":20611,"journal":{"name":"Proceedings of the Voronezh State University of Engineering Technologies","volume":"22 6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79808371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main characteristics of a complex system of unsaturated plasticizer-bromine using the main "working components" - isomers of 2-ethylhexyl-2-ethylhexene phthalate are considered. It is taken into account that the phthalate-type ester plasticizer is a polar compound with a dipole moment at the level of dioctyl phthalate included in its composition. It has been shown that in the process of bromination, molecular bromine enters into physical interaction with all components of the plasticizer. Dosed introduction of bromine into the system at high stirring speeds leads to the formation of a homogeneous thermodynamically stable system, since the solubility parameters of the components are practically the same. Using a model mixture of bromine-dioctyl phthalate-dibutyl phthalate, it was shown that mixing bromine with plasticizers in any investigated ratios does not lead to the appearance of the boundary “bromine in a plasticizer” or “plasticizer in bromine”. This established the unlimited solubility of bromine in the plasticizer under the conditions of its bromination. Using the method of UV spectroscopy on model mixtures of acetic acid-bromine-water; acetic acid-bromine-hexane, it was proved that in a real system, unsaturated plasticizer-bromine, bromination is most likely carried out only with molecular bromine without the formation of bromine dimers. The mechanism of bromination of unsaturated phthalates included in the plasticizer is shown. A system of kinetic equations in dimensionless variables is proposed. It was found that the nature of the theoretical curves significantly depends on the rate of introduction of bromine with a constant reaction mechanism. A change in the limiting stages of the bromination process was noted depending on the rate of bromine introduction into the system.

Various types of membrane units, including standard units for permeate separating, which are currently used for various liquids processing, are considered. Their advantages and disadvantages, working conditions and operating features are assessed. The principle of operation of membrane units with the bleed of the polarization layer is analyzed. A distinctive feature of such devices is the separation of the feed stream into three parts: adjacent to the membrane, including a polarization layer, with an increased concentration of high molecular substances (HMS) – concentrate, a spent stream core to be re-processed – retentate, and permeate, that practically contains no HMS. The unit scheme and the principle of operation of the plant completed with this equipment are given. A feature of this plant is the parallel arrangement of the membrane devices. In this configuration of the plant, there are two flow circulation loops and two tanks, in one of which there will be a depleted solution, in the other the retentate. During operation, the circulation of the depleted flow is provided. In this case, the resulting polarization layer (concentrate) will be discharged into the second tank. The working process continues until the complete depletion of the solution in the first tank. In the event that the solution in this tank is exhausted, and the required concentration of the product has not been reached, the second tank with the concentrate activates and the process continues. The principle of operation in this case is similar. The rotation of tanks continues until the required degree of concentration of the product is obtained. A calculation algorithm, a block diagram and a program for calculating the operating time of a membrane installation are proposed, for which a certificate of state registration of a computer program has been obtained. The calculation algorithm and program interface are presented. This program makes it possible to predict the operation of such installations and provides for the possibility of optimizing their operation.т.п.)
