Influence of fertilizers on the productivity of tea plants in the conditions of the north-west Caucasus

The research is aimed at finding effective ways to regulate the functional state of tea plants under stress, increase in yield and its stability, preserving and improving the quality. Foliar spraying of the tea stimulated the active formation of Proline (135.1-179.2 mg/g, in the control - 122.6 mg/g) and ascorbic acid (177.8-226.5 mg/g, in the control - 131.4 mg/g) in the leaves, which indicates the inclusion of processes associated with the mechanism of nonspecific protection against stress. The optimal state of tea plants treated with fertilizers explains the more developed specific surface density of the leaf (1.44 mg/cm2, in the control -1.24 mg/cm). The developed specific surface density of the leaf was ensuring the active operation of the leaf apparatus on the experimental variants, which is expressed in a higher productivity of the leaves (1.27-1.31 g/dm2), compared to the control plants. The highest yield (about 23.05 centner per ha) was observed in the variant with foliar treatments with rokogumin, in the variant with sodium humate (31.47 centner per ha), the yield exceeded the control (26.88 centner per ha) only in 2020, which may be due to the accumulative effect.

Immune status of piglets after administration of Iron(IV) clatrochelate to pregnant sows

The degree of the physiological development of the body of piglets in the first months after birth is important because, during this period, there is an active formation of many organism systems, including those that provide homeostasis. The resistance of piglets to diseases of various etiologies during life depends on the formation of the immune system. Our study aimed to assess the immune status of piglets born to sows that received injections of solutions of Iron(IV) clatrochelate and cyanocobalamin during pregnancy. To achieve this goal, two groups of newborn piglets-analogs were formed during their retention with suckling sows – control and experimental, 15 animals each. Piglets from 5 sows (3 from each) were injected into the experimental group, which were injected 10 ml of 10 % solution of Iron(IV) clatrochelate and cyanocobalamin solution twice during pregnancy (14 and 7 days before the expected farrowing) intramuscularly. Piglets of the control group, according to the traditional scheme of prevention of iron deficiency anemia on the second day of life, were administered irondextran drug uniferon (200 mg of iron (III) per injection). Piglets and sows were observed for two months; for studies of the content of immunoglobulins in the piglets' serum, the blood samples were taken at 1, 5, 12, and 30 days of life. During the experiment, the indicators of the content of immunoglobulins of classes G, A, M in the serum of piglets of the experimental group and the dynamics of their changes within 30 days after birth did not differ from the control. Two injections of 10 % solution of Iron(IV) clatrochelate in a dose of 10 ml in combination with cyanocobalamin injections at a dose of 500 mg of active substance to pregnant sows 14 and 7 days before the expected farrowing did not adversely affect the immune status of newborn piglets. Furthermore, this has a high prophylactic effect against iron deficiency anemia.

Efficiency of Application of (Mo, Al)N-Based Coatings with Inclusion of Ti, Zr or Cr during the Turning of Steel of Nickel-Based Alloy

The article compares the properties of multilayer composite wear-resistant coatings of Zr–ZrN–(Zr, Mo, Al)N, Ti–TiN–(Ti, Mo, Al)N, and Cr–CrN–(Cr, Mo, Al)N. The investigation was focused on hardness, resistance to fracture during scratch tests, elemental composition, and structure of the coatings. Experiments were carried out to study the wear resistance of coated carbide tools during the turning of 1045 steel and of NiCr20TiAl heat-resistant nickel alloy. With the elemental compositions identical in the content of molybdenum (Mo) and aluminium (Al), identical thicknesses and nanolayer periods of λ, the coatings being studied demonstrated a noticeable difference in wear resistance. Both during the turning of steel and nickel-based alloy, the highest wear resistance was detected for tools with the Zr–ZrN–(Zr, Mo, Al)N coating (the tool life was 3–5 times higher than for uncoated tools). The good wear resistance of the Zr–ZrN–(Zr, Mo, Al)N coating may be related to the optimal combination of hardness and plasticity and the active formation of molybdenum oxide (MoO3) on the coating surface during the cutting, with good tribological and protective properties.

Violin sonata fis-moll by Paul Natorp in the context of genre development

Исследуется творчество композитора-философа Пауля Наторпа, фигура которого в русскоязычном музыкознании практически не представлена. Отдавая себе отчет в том, что его творчество может вызывать интерес с самых разных точек зрения, мы фокусируем свой научный интерес на Сонате fis-moll для скрипки и фортепиано, созданной в период активного формирования новых художественных течений в музыке начала ХХ века. На примере произведений так называемого «второго ряда» Соната fis-moll может служить довольно ярким примером процессов обновления музыкального языка, в том числе на основе переосмысления классического наследия. Музыковедческий анализ Сонаты для скрипки и фортепиано fis-moll осуществляется в опоре на историко-стилевой метод и интертекстуальность. Доказано, что, будучи созданной в русле традиций Бетховена, Шумана и Брамса, Соната fis-moll для скрипки и фортепиано отмечена самобытностью и оригинальностью. Теоретическая значимость работы определяется заполнением лакуны в истории становления жанра скрипичной сонаты в немецкой композиторской школе. Практическая значимость связана с возможностью обогатить скрипичный репертуар за счет знакомства с камерным жанром, представленным в творчестве немецкого музыканта-философа. This work is dedicated to the work of the composer-philosopher Paul Natorp, whose figure is in practice not represented in Russian-language musicology. Realizing that P. Natorp's work can arouse interest from a variety of points of view, we focus our scientific interest on the fis-moll Sonata for violin and piano, created during the active formation of new artistic trends in music at the beginning of the twentieth century. Using the works of the so-called “ second row” as an example, the fis-moll Sonata can serve as a vivid example of the processes of updating the musical language, including on the basis of rethinking the classical heritage. The musicological analysis of the fis-moll Sonata for violin and piano is based on the historical-stylistic method and intertextuality. It is proved that, being created in line with the traditions of Beethoven, Schumann and Brahms, the fis-moll Sonata for violin and piano by P. Natorp is noted for its musical identity and originality. The theoretical significance of the work lies in filling a gap in the history of the formation of the violin sonata genre in the German school of composition. Practical significance is associated with the opportunity to enrich the violin repertoire through acquaintance with the chamber genre presented in the works of the German musician-philosopher.

The Main Factors Influencing the Socialization of Students in PostPandemic Period

Successful reform of the higher education system in the context of COVID-19, both in a single country and in the world in the context of its development toward democratization, requires updated approaches to assessing the results of socialization of various categories of young people, and especially students. Since student age is a period of active formation of the inner need of a person to correlate his own aspirations with the interests of society, it is sensitive for the assimilation of social experience, socially significant activities, and the formation of an active creative personality. Higher education in the context of COVID-19 faces an important task - to ensure the education of "vital and socially competent person who can make independent choices and make responsible decisions in various life situations" the formation of their own motives and interests. It is important how much the student as a subject of socialization, independent in the information space, what is the level of his social competence, how quickly he chooses the field of activity in which he can achieve high professionalism. The article deals with the problem of socialization of student youth in modern conditions of a higher educational institution, associated with the processes of development and education of the individual. The features, stages and socio-pedagogical conditions of successful socialization of students in the context of COVID-19 are revealed.

Ukrainian Innovation Policy: The Smart Specialization Problem

The aim of the article is to reveal the place and role of smart specialization strategy as one of the relevant and central areas of modern economic policy. It is shown that in Ukraine the issue of economic essence and main goal of smart specialization policy as a form of state innovation policy remains theoretically and practically unexplored, as well as the importance of involving universities in smart specialization strategy in the context of creating basic innovations that can become the basis of the regional smart specializations.The article substantiates that the Ukrainian expert community is dominated by the perception the smart specialization strategy is the traditional sectoral economic policy, which considers innovation as a factor of increasing the competitiveness of existing industries, i.e. without much change in the technological structure of the economy or region. The article argues that the main content of the smart specialization policy should be the priority development of new high-tech sectors of the economy, industries belonging to the current and future technological paradigms.The results of studying the main development directions of the Top European innovation Universities are presented. These results testify to the close connection between the innovation Universities and the creation of basic innovations for the development of new high-tech business. The analysis showed that Ukraine not only cannot enter the European ranking of innovation Universities, but also lags far behind the total number of European patents per country. This shows that the country has in fact abandoned basic innovation competitions with Europe. The policy of smart specialization should help to correct this situation. The positive effect of such policy largely depends on the active formation of modern innovation Universities, which can create and commercialize basic innovations of the Schumpeter’s type, leading to the emergence of new high technologies.

METHODOLOGICAL APPROACHES TO THE STUDY OF THE UPBRINGING OF MODERN YOUTH BASED ON FAMILY VALUES

From time immemorial, society has been characterized by a specific set of values, the system of which acts as a high level of regulation.Value systems are formed and transformed in the historical development of society.In each society, the value system is determined by the sociocultural, historical, political, cultural, economic conditions of its development, trends in social dynamics, the specifics of a particular period of functioning of society with its difficulties and prospects.The system of values consists of three elements - universal, cultural and individual.This article is aimed at considering methodological approaches to the study of the education of modern youth on the basis of family values, which is included in the element of individual values.The family is one of the main life values for people all over the world and as a system is characterized by the presence of connections and relationships (marital, consanguineous and others) between its constituent elements (family members) and manifests its integrity with an indissoluble unity with the environment (sociocultural reality).Modern youth is going through the process of active formation and development in the family, therefore, in the process of adaptation to the rapidly changing sociocultural reality, they use the system of family values, adapting it to modern conditions.The axiological, personality-activity, gender approaches were also methodological guidelines in the upbringing of the attitude to family values among modern youth.Thus, family values and trends characterizing the state of the family are significant social indicators that educate today's youth.

“Pension capital” in representations of large cities residents: the experience of sociological analysis

The article discusses the possibility of applying the theories of human and social capital to the sociological study of “pension capital”. The authors methodologically substantiate that “pension social capital” in modern Russia already has certain institutional characteristics. On the example of an applied sociological study carried out with the financial support of a grant from the Russian Foundation for Basic Research, it is revealed that the public opinion of residents of large cities is dominated by attitudes towards paternalistic, traditional ways of forming pension capital. Responsibility for the future provision of pensions is massively entrusted to state institutions by the townspeople. Alternative sources of pension savings are perceived by the population as secondary, not enjoying special trust. The team of authors comes to the conclusion that among active citizens, groups are formed that have a special potential for future active formation of social pension capital.

Japanese cabbage: features of morphological and biochemical parameters of a promising sample

Relevance. New types of vegetable crops, previously unknown on a large scale, appear on the market. Japanese cabbage (Brassica rapa L. subsp. nipposinica (L. H. Bailey) Hanelt) is one of such crops for the middle zone of the Russian Federation. Due to the high content of vitamin C and microelements, Japanese cabbage can be classified as a rational balanced diet, including dietary one, and it can also be used as a raw material for the medical industry. Methods. The study of a promising sample of Japanese cabbage selection at the Federal Research Vegetable Center consisted in phenological observation of the stages of plant growth and development, morphological study of economically valuable traits, and biochemical analyzes of the content of ascorbic acid, dry matter and photosynthetic pigments. Results. The results of observations made it possible to establish the timing of the onset of phenological phases in Japanese cabbage plants and showed that the active formation of leaf mass in plants occurs 20 days after planting the seedlings. A close direct relationship was established between the duration of economic shelf life and the number of leaves in a plant (R = 0.95) and the length of the leaf plate (R=0.92). In the conducted biochemical studies, it was revealed that the content of ascorbic acid in the promising sample is 37.84±0.88 mg%, and the dry matter is in the range of 11.3±0.42%. The content of antioxidants in terms of HA and AA is within 5.72±0.72 and 19.5±2.46 mg/g, respectively. The study of the morphological characteristics and biological characteristics of Japanese cabbage plants contribute to the maximum use of the potential of vegetable crops in the conditions of the Moscow region.
