The main task of financial management in groups of companies is to coordinate financial flows and improve the efficiency of their management. The search and substantiation of economically feasible solutions to these problems is hampered by the presence of many different types of consolidated associations that do not allow a single approach to financial management to be applied. Therefore, the processes of modeling financial flows of groups of companies based on modern principles of financial management are gaining relevance. The purpose of this study is to develop a model for managing the financial flows of a group of companies, taking into account the specifics of its activities within the framework of the formation of an effective financial management system. A systematic approach, theoretical and practical research of specialists in financial management, methods of economic and mathematical modeling are used. The paper substantiates the need to form a single financial center in groups of companies that performs treasury, clearing and credit functions, identifies the features of the implementation of financial functions by a single financial center within the type of a group of companies. Models for managing financial flows of a group of companies are proposed, which are an algorithm for maximizing individual positive synergistic effects of a group of companies that are predicted to be obtained as a result of performing functions assigned to a single financial center. The practical value of the work lies in the possibility of using the presented models for managing financial flows in the activities of Russian groups of companies and integration associations, which contributes to the formation of an effective financial management system. It is concluded that building a model for managing the financial flows of a group of companies involves defining the target function of the activities of the companies that are part of the group, and setting a system of restrictions in which the participants have to work; development of an algorithm for the optimal distribution of financial resources between participants, carrying out mutual settlements and implementing intragroup lending.

In Russia, as well as all over the world, one of the most acute problems is the protection of natural water resources from sewage contamination of food, especially dairy processing enterprises. However, despite the fact that restrictions, fines and suspension of their activities have been established at the legislative level for exceeding the established standards for the discharge of pollutants into reservoirs, they continue to cause more and more significant harm to the environment. The main objective reason for this phenomenon should be attributed to the lack of an effective technology for cleaning complex in composition, with changing even during the day physico-chemical properties of effluents of milk processing enterprises. The purpose of the study was to develop the concept of deep processing of secondary dairy raw materials for subsequent use in industrial production. The paper presents an analysis of the basic structure of the modern technology of wastewater treatment of dairy processing enterprises at factory treatment facilities and suggests the basic principles of processing secondary dairy raw materials. The analysis of the presented data shows that modern methods of wastewater treatment used in most dairy plants do not meet the standards. Following the proposed principles will ensure favorable conditions for the release of lactose from secondary dairy raw materials at subsequent stages of its deep processing. One or another combination of these processes primarily depends on the cost of technologies and the equipment necessary for their implementation, the volume of raw materials, the required depth of its processing, as well as the market price of finished products.

This research has been performed in the Ethylene Oxide production process. It is a flammable and colorless gas at temperatures above 11 °C. It is an important commodity chemical for the production of solvents, antifreeze, textiles, detergents, adhesives, polyurethane foam, and pharmaceuticals. Small amounts of Ethylene Oxide [EO] are used in manufacturing fumigants and sterilants for spices and cosmetics, as well as hospital sterilization for surgical equipment. Modern Ethylene oxide [EO] productions employ either air or oxygen (O2)to oxidize ethylene (C2H4) with a silver catalyst on an alumina oxide carrier[Ag/Al2O3]catalyst packed in a fixed-bed reactor (plug-flow reactor)but the oxygen-base reaction process is more desirable here we used oxygen. Mainly two reactions occur, partial oxidation of ethylene to ethylene oxide and total oxidation of ethylene to carbon dioxide and water. The design models of the process in this research based on a three-part system. They are: the reaction system, absorption system and Ethylene Oxide [EO] purification system. The largest cost in production of ethylene oxide is ethylene therefore, it’s important to optimize the selectivity towards ethylene oxide and thus reduce the consumption of Ethylene. The aim of this work is to create a simulation model of the Ethylene Oxide production process from Ethylene using Aspen Hysys V9. Also to knowing the optimum operational conditions (temperature –pressure –flow rate) for the oxidation reactions of Ethylene. The simulation was running three times with various operational conditions to make a good result. The conclusion was that during operational time the activation energy increased for both reactions which have to be compensated with increasing reactor temperature. At the same time the selectivity for producing Ethylene Oxide decreases, i.e. more carbon dioxide and water are formed. The simulation models yield Ethylene Oxide with purity of 99.2%.

Consumption of fermented milk products containing healthy substances is an effective means of strengthening the protective functions of the human body. Development of the new product technology is based on a well-founded method of introduction of plant components forming their composition and properties. The purpose of this work is to study the method of adding a mixture of aronia and hawthorn powders, the effect on organoleptic indicators and individual physicochemical properties of yogurt. During the work, a set of generally accepted standard research methods was used. The subjects of the study are samples of yogurt produced by a thermostat method, but differing in the step of introducing an enrichment additive. Digestion was performed using a dry bacterial starter for "vivo" brand yogurt. Based on the results of the study, the stage and method of adding a plant additive to the milk mixture are selected. The optimal dose for adding aronia and hawthorn powders to the milk mixture was 5%. It has been found that the addition of the additive before fermentation leads to a deterioration in appearance and consistency (whey peel off), and when a mixture of aronia and hawthorn powders is introduced at the fermentation stage, it contributes to an improvement in organoleptic indices of goat's milk-based yogurt. According to physical and chemical indicators, the developed sample according to the proposed technology meets the requirements set by TR TS 021/2011, TR TS 033/2013 and GOST 31981.

Trends caused by digital transformations in the economy have led to the formation of new forms of interaction between industrial enterprises, industries and complexes. Digital ecosystems are becoming a tool for ensuring sustainable economic development, requiring the development of conceptual foundations and methodological provisions for sustainable development in the context of the application of the ecosystem approach within the framework of spatial interaction of economic entities. The increasing role of digital assets and methods of their use within digital ecosystems is becoming an integral part of the formation of resource potential that ensures sustainable development with ecosystem interaction of participants, which indicates the development of competition not between individual companies, which is inherent in the traditional economy, but between the ecosystems being formed. Thanks to ecosystem interaction, participating companies focus more on external interaction, innovative priorities in management technologies, the creation of a rapidly adaptable value chain, the accumulation of knowledge and the build-up of digital assets. Territorial boundaries become conditional, competitive relations within the ecosystem become partner-oriented, aimed at increasing the return on network effects obtained through the interaction of digital platform participants. Ecosystems as more flexible structures have the property of rapid response to changes in the external environment and the ability to adjust to target requirements and tasks, rapid market coverage, technology adaptation and the creation of new business models. The structural changes taking place as a result of the digital transformation of the economy in various sectors of the economy show an increasing interest in the development of digital manufacturing enterprises and the transition to high-tech production. Digital transformation of activity is inextricably linked with ensuring sustainability of development, and such components of the ecosystem as flexibility and adaptability, as well as complementarity of assets, allow optimizing the sustainability of the socio-economic system.

The problems of extrusion process influence on the fatty acid composition of products obtained from the cake of cruciferous oilseeds (rapeseed, camelina) were considered in the article. Cakes of these crops have a wide range of uses for fodder purposes, which indicates their high biological value. The aim of this study was to evaluate the biological effectiveness of rape and camelina cakes before and after the extrusion process accorfding to the calculation of the rationality coefficient of the fatty acid composition. An increase in the content of saturated fatty acids and a decrease in unsaturated fatty acids were revealed during studies after extrusion processing. A decrease in the amount of linolenic acid was also noted in the work. Its amount decreased by 2.24% in rapeseed cake and by 2.63% in camelina cake after extrusion. It was determined that the coefficient of unsaturation of oils in rapeseed and camelina cakes decreases after extrusion by 4 and 3% for rapeseed and camelina cakes, respectively. The calculation of the rationality coefficients of the fatty acid composition showed an increase in the biological efficiency of oils in rapeseed and camelina cake after extrusion. The balance of the fatty acid composition increased after extrusion by 0.07 fractions of a unit in rapeseed cake and by 0.04 fractions of a unit in camelina. The use of the extrusion method in the processing of cruciferous oilseeds makes it possible to expand the range of raw materials for the feed industry, obtain feed that is safe for feeding animals and poultry, does not reduce its quality during storage and increases the energy value of the diet, and provides opportunities for the development of food products with increased content of essential fatty acids as well.

The world does not stand still. We are daily confronted with the achievements of modern science: we are able to communicate with a person from another continent via the Internet, we easily bypass any distance thanks to different modes of transport. And yet there are things that cannot be automated, improved, accelerated yet. A person still needs to sleep, have some physical activity during the day and, of course, eat. The whole day of a person can easily obey the rhythm: breakfast, lunch, dinner, and, of course, snacks, afternoon tea, brunch, late dinner. And it's getting harder and harder to give up food, as store shelves are bursting with goods that are ready to lie there for years until we buy them. This is because most of the foods we consume contain various dietary supplements in their composition. The main purpose of which is to make them tastier, stored longer, etc. Undoubtedly, the nutrition of all population groups can be affected by food additives, but in this article we will consider young people: 2nd and 3rd year students. Of course, studying, writing course projects, a large number of practical and other classes deprive you of the opportunity, or rather the strength and desire, to eat right. Therefore, this age group is of particular interest. To what extent are students aware of the presence of food additives in their food? How many of the survey respondents monitor their diet? And in general: are dietary supplements as harmful as they say in the media? In this article, we will analyze the survey data of students, as well as understand what dietary supplements are and how they affect the body.

The work noted the relevance of the development of the military-industrial complex of Russia. An analysis of sales volumes of a number of the largest enterprises of the military-industrial complex of the Russian Federation was carried out, as a result of which two leading organizations were identified. The value of the sales indicator for one analyzed enterprise was evaluated, indicating the reasons for the high results in three enterprises. Based on the analysis of data on the number, conclusions were made about the priority of large enterprises in the structure of the military-industrial complex of the Russian Federation and about the rather serious attention paid by the state to the development of the military economy in modern conditions. When considering the territorial location of the analyzed enterprises, the employment of employees of large organizations of the MIC industries in various regions of Russia is clearly shown, which serves as one of the main factors in the development of the regional economy throughout the country. It was noted the place of the largest enterprises of the military-industrial complex in the ranking of the 100 largest military-industrial companies in the world, based on income from sales of military products by world manufacturers in 2020. The build-up of the country's military power directly depends on the potential of military-industrial complex enterprises and the directions of their development. In the ranking of the analytical company GlobalFirepower for 2020, Russia was ahead of China, but lost to the United States. There are different opinions about the objectivity of this and similar ratings. However, it is impossible not to pay attention to the values of those factors in the GlobalFirepower rating, which indicate insufficient attention to them from the military-industrial complex of the Russian Federation at the present time.

An analysis of sales volumes of a number of the largest enterprises of the military-industrial complex of the Russian Federation was carried out, as a result of which two leading organizations were identified. The value of the sales indicator for one analyzed enterprise was evaluated, indicating the reasons for the high results in three enterprises. Based on the analysis of data on the number, conclusions were made about the priority of large enterprises in the structure of the military-industrial complex of the Russian Federation and about the rather serious attention paid by the state to the development of the military economy in modern conditions. When considering the territorial location of the analyzed enterprises, the employment of employees of large organizations of the MIC industries in various regions of Russia is clearly shown, which serves as one of the main factors in the development of the regional economy throughout the country. It was noted the place of the largest enterprises of the military-industrial complex in the ranking of the 100 largest military-industrial companies in the world, based on income from sales of military products by world manufacturers in 2020. The build-up of the country's military power directly depends on the potential of military-industrial complex enterprises and the directions of their development. In the ranking of the analytical company GlobalFirepower for 2020, Russia was ahead of China, but lost to the United States. There are different opinions about the objectivity of this and similar ratings. However, it is impossible not to pay attention to the values of those factors in the GlobalFirepower rating, which indicate insufficient attention to them from the military-industrial complex of the Russian Federation at the present time.","PeriodicalId":20611,"journal":{"name":"Proceedings of the Voronezh State University of Engineering Technologies","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89163149","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 number of cars used worldwide is constantly growing. In this regard, the problem of combating atmospheric pollutants - exhaust gases of internal combustion engines is of particular relevance. Over the years, automakers have made many improvements to car engine design and fuel systems to meet pollution limits. One of the best solutions to this problem is the use of a so-called catalytic converter (converter) or simply a catalyst with a high content of noble metals, the main function of which is the simultaneous oxidation of unburned hydrocarbons and CO, as well as the reduction of nitrogen oxides. It was found that the addition of rare earth metals to Pd, Pt catalysts improves their properties and reduces the proportion of noble metals in the composition of catalysts. The paper presents the results of a study of complexation in the Eu3+-ligand system, where the ligand is an organic acid, by photocolorimetric and potentiometric methods. In the Eu3+-gallic acid system, a stable complex of the composition MeLnx – 1:2 is formed. In the Eu3+- oxalic acid system, a stable complex of the composition MeLnx – 1:1 is formed. In the Eu3+-valine system, a stable complex of the composition MeLnx – 1:2 is formed. A new technique for obtaining complex compounds is shown, consisting in adding hydrogen peroxide H2O2 to a solution containing solutions of Eu3+ salt and organic acid in an aqueous-alcoholic medium to block the reduction of Eu3+→Eu2+. A technology for obtaining a automotive catalyst has been developed, consisting of successive stages: obtaining complex compounds, applying the obtained complex compounds to ceramic block matrices, drying, applying platinum (palladium) acid, calcination. The presence of the Eu3+ ion in the ceramic matrix is proved by the method of elemental analysis. The technology can be applied to solve the problem of environmental pollution, such pollutants as exhaust gases of cars containing a lot of harmful substances in their composition.

Sunflower proteins, due to their high nutritional and biological value and wide distribution in the Russian Federation, are promising raw material for the production of food protein products for use in therapeutic and preventive and infant nutrition. In this regard, when choosing sunflower varieties, special requirements are put forward to them: a sufficiently high protein content and a high proportion of the kernel in the seeds, a balanced amino acid composition, compliance of safety indicators with the standards of technical regulations. VNIIFАТs conducts long-term research on the development of technology for protein concentrate and sunflower seed isolate. In cooperation with VIR, scientific work devoted to the selection of sunflower varieties that allow to obtain protein products with optimal properties is carried out. Functional properties, nutrient composition and physico-chemical parameters of sunflower protein concentrate have been studied. It is shown that sunflower protein is not inferior in its properties and biological value to soy protein concentrates presented on the Russian market. Therefore, it can be recommended as a protein and functional additive in therapeutic preventive and baby food products.
