At the present stage of development, in order to ensure the fulfillment of various kinds of tasks of national importance, systems based on groups of low-orbit communication spacecraft are increasingly being used. An example of such satellite systems is the Gonets Satellite System JSC, which provides mobile satellite channels for mobile and stationary subscribers anywhere in the world and is being developed by order of the Roskosmos state corporation for comic activities. Therefore, in view of the importance and in some cases the confidentiality of the tasks performed, the requirements for stealth and noise immunity for these systems are increasing. Increasing secrecy, namely, its information component, is possible through the use of an authentication protocol based on evidence with zero knowledge disclosure, which operates on the basis of modular codes. However, the modular codes in some systems are also used to combat equipment failures and malfunctions, and when introducing more redundancy, they are also able to localize errors caused by interference in the communication channel. Thus, using modular codes to ensure stealth, to combat failures and malfunctions, as well as to provide noise immunity, it will allow you to switch to a single mathematical apparatus for constructing the system and thereby move away from the traditionally used cascade codes. Therefore, the task of developing a new method for constructing a modular composite code to ensure noise immunity is relevant.

Development of new and improvement of existing types of equipment implies the intensification, environmental friendliness and energy efficiency of their processes. Studies of various energy effects on raw materials of animal and plant origin have shown that electric technologies are the most promising for intensifying the process of processing raw materials of animal and plant origin. Special attention should be paid to electron-ion technology, namely the process of applying an electric field directly or through the working medium to the processed raw materials. The most relevant issue is the environmental safety of equipment and service personnel, as well as environmental monitoring, where the technology is used using an electric field. The influence of powerful electric fields in the process of inducing electrical impulses, namely, the influence of negative side effects, both in the direction of electromagnetic characteristics and possible x-rays, has not been studied yet. The effectiveness of using electron-ion technology depends on a deep and comprehensive study of the positive and negative aspects of the influence of the electric field on the environmental condition of the product, production and people.

Modeling various parts is an integral part of the design process. At the modeling stage, it is necessary to identify places that are more susceptible to high loads and stresses. As a result of the analysis of the identified areas, actions should be taken to eliminate them for further development.

In the Russian Federation, there is a need for biologically active vitamin and antioxidant complexes of natural origin. At the present stage, it is possible to single out a promising universal bioactive composition, such as the carotenoid pigment complex lycopene (E-160d). The expediency of using room temperature when defrosting watermelon pulp is due, in addition to the above reasons, also to a noticeable increase in the proportion of separated juice, which facilitates the drying of the residual pulp due to a decrease in its moisture content and sugar content in it. At the same time, due to the insolubility of lycopene in water, it can be argued a priori that it is not removed with the separated juice and, as a result, its relative content in the residual pulp increases. The object of the study was blocks of pulp of ripe watermelons, provided their red color scale, which has a positive effect on the extraction of lycopene. The aim of the study is to define. Heat and mass transfer parameters when defrosting watermelon pulp. To achieve this goal, the following tasks were solved: determination of cryoscopic temperature: determination of the amount of frozen moisture depending on temperature; determination of the moisture content of the pulp of watermelon, after defrosting and the proportion of separation of the released liquid phase; determination and ratio of liquid and initial product consumption; determination of the sugar content of thawed watermelon pulp. The residual presence of moisture and sugars in berries and fruits after their defrosting plays a significant role, because determines its structural organization and consistency, which results in its stability during subsequent processing or storage. The sugar content of the thawed pulp of watermelon is 6.3%, therefore, like the watermelon in general, it can be classified as a fruit and vegetable product with a high sugar content. The ratio of the flow rates of the separated phases after thawing is calculated.

The article is devoted to the consideration of methodological approaches to identifying and evaluating factors that influence the activity of modern students. In modern sociology, as a rule, the general theoretical problems of youth and youth policy are analyzed. Actively conducted empirical research in the framework of youth issues is aimed at collecting statistical data, as well as studying various aspects of the state of youth. The subject of this research is new approaches and methods to the study the factors of social and political activity of students. The research is based on the methodology of a comprehensive approach: system, political and sociological analysis, methods of expert assessments, in particular, the rank method , structural-functional and factor analysis. The article presents the main conclusions based on the results of socio-political research of the student environment of the faculty of history of the Krasnoyarsk State Pedagogical University named after V.P. Astafiev. The analysis of empirical data obtained as a result of a questionnaire survey of students allows us to identify factors that affect their activity in the socio-political space, and formulate proposals for adjusting the methodology of working with modern students.

The analysis of the study of identities and semantic constructions of the value consciousness of the inhabitants of the Republic of Crimea and Sevastopol in ethnic groups is presented. The approach of the social anthropologist F. Barthes about the change of ethnic identity is used, with the help of which the process of the formation of the identity of the inhabitants of Crimea in the new socio-political reality is analyzed. The authors tried to understand how social processes contribute to the preservation of ethnic status, which occurs when ethnic characteristics are blurred or changed. The empirical model of the study included a mass survey of 2000 residents of the cities of the Republic of Crimea and Sevastopol. The object of the study was the inhabitants of the peninsula, during which three groups were singled out according to their ethnicity: those who consider themselves to be Russians - into the group of "Russians", who identify themselves as Ukrainians - into the group "Ukrainians", who refer to the Crimean Tatar population - into the group "Crimean Tatars ". The authors associate the understanding of the process of formation and change of identities among residents of the Crimean peninsula with factors of the social environment, communications, political and economic benefits. As a conclusion, the authors note that the process of forming identities in various ethnic groups of Crimea should be based on the principles of regional patriotism, taking into account territorial attachment to Crimea, creating unifying cultural codes, providing open alternatives, social opportunities, social trajectories of success that ethnicity can transmit.

The author examines the relationship between politics and sports in the aspect of political theology. The relevance of the topic of the article lies in the need to understand the relationship between politics and sports in modern conditions. As the goal of the article, the author sets the search for an approach to the problem of the relationship between religious, political and spiritual on the basis of sports activity. In the first part of the article, the author conducted the necessary analysis of the concepts of spirituality as comprehension of God in a religious aspect, and in the second part he focused on defining the concept of spirituality in sports politics. It is concluded that politics should not be seen as the only determining factor in sports spirituality. The religious perspective of the resacralization of the political field of sport is no less important and essential in modern Russian society. As a result, the functions of sports spirituality in sports policy were revealed and the applied aspect of this direction was indicated.

The study analyzes the problems of juvenile delinquency from a socio-political point of view. It is noted that the crime among the youth that is growing from year to year causes serious concern, both in society and in government structures. Many young offenders are themselves victims of social instability, which requires government efforts to balance public and personal interests. It is concluded that the criminalization of youth is an international problem that is characteristic of most states in the modern world. The article considers juvenile delinquency and justice from a socio-political point of view. Many argue that we have a long way to go before we arrive at child-friendly juvenile justice. Around the world, there are different and inadequate legal frameworks that do not correspond to the age of offenders, there are no specialized juvenile services and facilities, and there is an acute shortage of specialists, which leads to problems related to the training and supervision of this vulnerable social group. The meta-analysis identified three main factors associated with effective interventions for juvenile offenders: the philosophy of "therapeutic" intervention, service for high-risk offenders, and quality of implementation. These results are consistent with factors that are thought to be associated with good outcomes in residential care centers for disadvantaged adolescents and juvenile delinquents: good staff-adolescent relationships, perceptions of staff as pro-social role models, positive peer pressure, individualized treatment program, related programs and activities, clear expectations and boundaries, and placements to maintain ongoing contact with the family. In society, coercive interaction styles have been found to be less successful in achieving adherence among juvenile offenders than a client-centered approach. The price of antisocial behavior of minors is high and falls on the shoulders of society and the state. The current climate of austerity in public services requires that any intervention is not only effective but also cost-effective, which poses challenges in implementing interventions for this vulnerable social group of young people. Thus, the relevance of such studies at the present time lies in the fact that, having summarized the opinions of various scientists, having analyzed modern Russian and foreign legislation, judicial practice, we must admit that the problem of criminalization of youth, both in our country and in the world as a whole has a pronounced socio-political character due to its influence on the fate of future generations and the states themselves.

The article examines one of the most important periods in the formation of the migration policy of the Russian Federation - the first decade of the XXI century, when there was a choice between the priorities of the development of the country's migration policy. Will it move along the path of securitization or humanization? It should be noted that this choice was faced not only by the Russian Federation, other countries-receivers of migration flows also had to make their choice in the light of the spread of international terrorism and the openness of borders for migration flows, which required the postulates of globalization.

The use of crushed sprouted grain in public catering products can increase the competitiveness of enterprises, because in the field of public catering, the trend towards healthy nutrition continues, one of the directions of which is grain germination. Grains have a high content of carbohydrates (including starch), it germinate in a humid and not always light environment. This promotes the multiplication of microorganisms. To suppress the growth of the number of microorganisms, it is proposed to use cold plasma radiation treatment.

Distance learning is now rapidly becoming more important. Universities compete with each other around the world, trying to attract the best students and teachers from all over the world. The digital age has changed the way people live, the way they receive education and upbringing. Everything around us is changing, and the attitude to learning must change accordingly. The role of international education is significantly increasing, since it is vital for the modern world to develop its own culture, develop and move forward. It is also vital to learn foreign languages in order to keep up with the times. Today, the knowledge of foreign languages opens a window to a large global world with its wide flow of information and innovation. At present, the modernization of educational system in Russia is associated with innovative processes in the organization of foreign language teaching. The main task of the teacher at the present stage is to choose methods and forms of organization of educational activities of students that optimally meet the goal. In recent years, the question of using new information technologies in higher education has been raised more often. Since the main goal of teaching foreign languages is the formation and development of the communicative culture of students, training in practical foreign language acquisition is a priority in education. The article discusses the possibilities of using electronic educational resources to ensure interactivity of the learning process. The study attempts to identify the features of the use of digital educational technologies in teaching a foreign language in higher education, advantages and disadvantages.
