Matrices with restricted entries and q-analogues of permutations

We study the functions that count matrices of given rank over a finite field with specified positions equal to zero. We show that these matrices are $q$-analogues of permutations with certain restricted values. We obtain a simple closed formula for the number of invertible matrices with zero diagonal, a $q$-analogue of derangements, and a curious relationship between invertible skew-symmetric matrices and invertible symmetric matrices with zero diagonal. In addition, we provide recursions to enumerate matrices and symmetric matrices with zero diagonal by rank, and we frame some of our results in the context of Lie theory. Finally, we provide a brief exposition of polynomiality results for enumeration questions related to those mentioned, and give several open questions.Comment: 29 pages, 2 figures, v2: one additional result, some formulas simplified, and a new reference; v3: corrected typo

Socio-Communicative Technology of Working with Public Opinion in the Context of an Environmental Incident

The article is devoted to the problem of resolving environmental incidents of various origins, building an effective crisis management model. The article examines the analysis of crisis communications, subjects of environmental communications, sources of information dissemination, response tools.   Target. Formation of a successful practice of overcoming the environmental crisis based on the development of an effective communication strategy and action model.   Methodology. In the course of the research, in order to form a theoretical base, the author turned to the works of Russian and foreign researchers studying the issues of social and communicative technologies, crisis communications. In the practical part, materials from the mass media, information from state bodies, and the author’s own experience in resolving crisis situations were used. To draw conclusions, strategies and actions in three different categories of environmental crises were evaluated and the results they led to.   Results. Issues of environmental protection and the quality of ecology are increasingly of concern to citizens, they quickly move from social to political. The ability to competently respond to overcoming environmental crises, minimizing their consequences can not only maintain the official position of a representative of state authorities and business stability, but also ensure social stability in society and trust in management institutions

Physics and chemistry of producing silicon-hydroxylapatite-titanium composite materials

In the research, Si-HA poweders have been synthesized using SBF solution with different content of silicon. It was found that all the samples synthesized from the model solution of extracellular fluid under varying concentration of silicate ions are single-phase and repesent hydroxyapatite. The nature of the reagent containing SiO[44]- ions does not affect the hydroxyapatite structure. In the study of the surface and morphological characteristics of the phosphate coatings modified by silicon ions, it was found that as the degree of phosphate calcium substitution by SiO[44]- ions increases, the surface wettability on the titanium substrates deteriorates and cohesive energy decreases. It is shown that the titanium coating is formed in three stages. After irradiation of titanium substrates coated with Si-HA, the crystals can keep growing and the surface can keep regenerating

Роль законодавства та державної політики в мінімізації впливу загроз екологічній безпеці в галузі автомобільного транспорту

The role of legislation and state policy in minimizing the impact of threats to environmental safety in the field of automobile transport has been studied. The main directions of the development of state policy and legislation in the field of reducing the negative impact of motor vehicles on the environment and public health have been defined. The main problems of reducing the negative impact of motor vehicles on the environment and public health, as well as the development of state and legal mechanisms to overcome them have been determined. The main environmental problems faced by governments are the use of internal combustion engines and fuel quality indicators. Many EU countries are refusing to further impose more strict requirements on the operation of motor fuel engines, instead introducing mechanisms to completely abandon such vehicle propulsion systems. However, such a refusal raises another problem of greening of road transport – the problem of electrification of transport, in the process of which it is necessary to solve the problems of transport energy and disposal of used batteries of electric vehicles. The authors have emphasized on inexpediency that to be limited in the long run only to mechanisms for setting more strict emission requirements for cars. The authors have indicated the need for a comprehensive approach to solving environmental problems to prevent the emergence of new significant difficulties – the accumulation of used batteries of electric cars, the depletion of non-renewable resources for their manufacture, etc. It has been offered to join Ukraine to the pan-European initiative of electrification of road transport, to develop the state program for the transformation of the motor transport industry with clear deadlines for the introduction of restrictions on the use of internal combustion engines, to introduce mechanisms to financially stimulate the transition from internal combustion engines to electric combustion engines.Досліджено практику державної політики та застосування законодавства в Україні та країнах Європейського Союзу в запровадженні вимог охорони довкілля від забруднення в галузі автомобільного транспорту, виявлено основні сучасні проблеми та виклики екологічній безпеці у сфері експлуатації автомобільного транспорту і трансформації транспортної галузі, запропоновано рекомендації щодо вдосконалення державної політики країн стосовно встановлення законодавчих вимог до автомобільних транспортних засобів

Финансы в России и мире: концептуальные аспекты

The modern digital economy requires “new finance”. The subject of the study is to clarify their content, and the goal is to develop the author’s view of the term of “finance”. The relevance of the topic is dictated by the need to analyze complex theoretical questions of technological transformation of financial markets and activities of financial intermediaries. The scientific novelty consists of the theoretical contribution of the theory of finance evolution in the digital era. The main research methods are systemic and logical approaches, the method of theoretical cognition, the historical method and the method of scientific abstraction. The results of the study are clarification the essence of finance and applied issues of their use in Russia and abroad. It will contribute to the development of a scientific doctrine of digital assets circulation; will allow to refine the model of the activities of financial intermediaries’ regulation in our country and lay the foundation for the formation of global norms and rules for the development of national and international financial markets of the CIS, the EAEU, the SCO, and BRICS countries. The conclusions of the study are: a) confirmation of the author’s position on the essence of finance. The paper indicates that, in the context of the economy’s digital revolution, the substance of economic categories stays constant, although their forms vary according to innovation, behavioral characteristics, and other factors; b) without rejecting the rational knowledge formed in the Western scientific school, the authors emphasize that the social sciences cannot be global, they have a national character; c) based on the investigation, the author defines “finance” as a distribution category in the development and utilization of financial resources.Современная цифровая экономика требует «новых финансов». Предметом исследования является выяснение их содержания, а целью — разработка авторской позиции толкования дефиниции «финансы». Актуальность темы продиктована необходимостью исследовать сложные теоретические вопросы технологической трансформации финансовых рынков и деятельности финансовых посредников. Научная новизна состоит в обосновании эволюции теории финансов в цифровую эпоху.

A ROLE FOR CELLULAR IMMUNITY IN EARLY POSTPARTUM PERIOD

The functioning of the secretory organs is closely related to the activity of the immune system. As is well known, this participation is manifested in the fact that at certain stages of activity, the lymphoid cells migrating to the organ can be involved in the regulation of secretion. In addition, the products of the immune system and even its cellular elements can become components of a number of secrets. Colostrum and milk contain a large number of cells of a wide spectrum (up to 1/3 of the volume), of which the number of lymphocytes is up to 16% of leukocytes. Lymphocytes, in an immunologically active form, entering the newborn’s body with colostrum, activate the cellular immunity system. The transport of lymphokinin mediators plays a certain role in this process. Microphages, T- and B-lymphocytes, penetrating through the intercellular spaces into the lymphoid layer of the intestine, transmit immunoreceptors to the prolymphocytes of the newborn, "armed" with their activity to recognize genetically foreign ones. The lymphocytes contained in colostrum are the cells of the immune system that provide cellular and humoral immunity. They are mainly represented by T-cells, B-cells and killer cells. Milk T-cells produce a full spectrum of immune regulatory proteins such as interferon, tumor necrosis factor alpha. These cells are the cells of the immune memory. Newborns who received the first portion of colostrum no later than an hour after birth are characterized by an increased number of leukocytes, more pronounced phagocytosis, which indicates the stimulation of hemo- and lymphocytosis. When carrying out transmission and scanning electron microscopy in the epithelial layer of the intestine, cellular elements were found that got there from the intestinal lumen. Microsections show how cells of a lymphoid nature, pushing apart the structures of the epithelial layer, bypass natural barriers and, at the same time, retain their physiological usefulness. The possibility of penetration of immunocompetent cells of the mother’s colostrum into the bloodstream of the young is proved using the natural label of the female’s cells – sex chromatin. Naturally, sex chromatin-labeled cells were sought in male newborns. The detection of colostrum cells in the intestinal wall and bloodstream of the young is approximately 25% in the blood, 1% in the lymph, and about 70% in the intestine. There is no doubt that the leukocytes of colostrum are of exceptional importance in creating immunity in newborn animals
