The article analyzes the current state of rhetoric as an academic discipline and the prospects for its study. Rhetorical skills and skills of the student are one of the significant results of educational achieve­ments. However, in Russia, their formation is hampered by the absence of the majority of native speakers of ideas about the logical, stylistic and ethical laws of public speech. Purpose of article - based on the analysis of works devoted to modern rhetoric, to characterize the state of rhetorical education in modern society and the place of rhetorical (communication) disciplines in the system of school and university education. The causes of the decline of rhetoric, the ways of its development as a factor in the education of a rhetorical person are considered, the problem of speech influence and its study in a higher educational institution is touched upon.В статье рассматривается современное состояние риторики как учебной дисциплины и перспективы ее изучения

Effect of water deficit on maize seeds (Zea mays L.) during germination

Received: October 29th, 2022 ; Accepted: March 23rd, 2023 ; Published: April 14th, 2023 ; Correspondence: [email protected] climate changes cause the frequent recurrence of droughts, which reduce crop production more than any other environmental factor. This study was conducted to access the effect of water deficit on maize seeds (Zea mays L.) DKC 5143 hybrid during germination. The tasks were to assess the influence of different rank of osmotic stress on the maize lipid peroxidation (LPO), proline content, catalase and aminotransferases activities, and morphometric parameters during the early stages of maize seeds germination. The maize seeds were exposed to five levels of water availability which produced by PEG-1500 solutions (0, 20, 50, 100, 200 g L-1 ). Seeds of maize were germinated on Petri dishes for 7 days under controlled parameters. Amounts of TBARS were increased in maize sprouted seeds by 1.9 times, coleoptiles by 1.4 times, and in roots - by 1.9 times under water deficit. Proline content increased by 9.2 times in coleoptiles and by 6.0 times in 7 days maize roots while PEG-1500 (200 g L–1 ) treatment. An increasing of catalase (CAT), aminotransferases (ALT, AST) activities according to osmotic potential value was also observed. A remarkable development of maize oxidative reaction was associated with a significant reduction in emergence, wet weight and length of water-stressed plants. These results assume that the maize adaptive strategy to osmotic stress during germination was found in the activation of LPO and antioxidant components. The findings provide useful help for correcting the stress state of maize using osmotically active regulators

Civic patriotism among young sportsman in the South of Russia: Sociological analysis and diagnostics

Purpose: This article is aimed at revealing the specifics of civil and Patriotic practices in the youth environment of the South Russian region. Methodology: The sociological study used methods of qualitative operational analysis and theoretical interpretation of the obtained empirical data, as well as methods of sociological diagnostics aimed at the conceptual generalization of the results of empirical research by social recognition of the qualitative characteristics of civil patriotism in the youth environment as an integral social phenomenon. Result: In modern Russian society, patriotism is positively perceived by the majority, including young Russians, who associate it with love for the Motherland and a willingness to stand up for it. However, state patriotism in the youth environment lacks citizenship, that is, the desire of young people to actively participate in social Affairs, working for the benefit of society and the social environment. Applications: This research can be used for the universities, teachers and students. Novelty/Originality: The sociological analysis and diagnostics reveal the reasons for the low level of civic patriotism among young people, as well as the factors that hinder its development in regional communities in the South of Russia.The article was completed as part of the implementation of the State Assignment (Ministry of Education and Science of the Russian Federation), project No. 28.3486.2017 / PC “Civil patriotism in the formation and development of solidarity practices in the south of Russia: resource potential and conditions for its implementation”

ETHNIC DIFFERENCE OF HEALTH DISORDERS IN INDIGENOUS ETHNIC GROUP OF BAIKAL REGION (LITERATURE REVIEW)

An analysis of the researches showed that the indigenous ethnic group of Baikal region has high level of adaptation to a place of residence in comparison with migrant. Rate and clinical manifestations of diseases in the Buryat ethnic group have significant differences from the Russian (moderate type 1 diabetes, severe reproductive disorders). Also, there are some differences of redox protection state in indigenous ethnic group of Baikal region that could be an additional biochemical marker of disease severity

The effect on nitrogen oxide emission from agricultural soils

The study investigates the effect of biochar on nitrous oxide emission in Endoargic Anthrosols in the southern territory of the Russian Far East. Biochar (bio-charcoal) was applied in the amounts of 1 kg/m2 and 3 kg/m2 in combination with organic and mineral fertilizers to drained and drain-free fields during the vegetation season, and the five-gas analyzer G2508 (Picarro) was used. Cumulative flows of N2O were estimated. The analysis revealed that biochar reduces the emissions and the cumulative flow of nitrous oxide. The higher the dose of biochar, the lower the emission and cumulative flows of nitrous oxide, regardless of a drainage system. Biochar (1 kg/m2) reduced the cumulative N2O flow from the soil by 52.2% throughout the experiment conducted, while a dose of 3 kg/m2 allowed for 97.8% reduction. The study found that organic and mineral fertilizers can be effectively used in combination with biochar, as N2O emission from the soil with mineral fertilizers is significantly higher than from the soil with organic fertilizers. Biochar (1 kg/m2) combined with organic fertilizers reduces N2O emission by 53.7%, while a dose of 3 kg/m2 can reduce emissions by 88.9%. Biochar (1 kg/m2) combined with mineral fertilizers reduced the flow of N2O by 17.5%, while a 3 kg/m2 dose of biochar used with mineral fertilizers reduced the emission by 85.3%

ETHNO-GENETIC MARKERS OF ANTIOXIDANT SYSTEM (LITERATURE REVIEW)

Oxidative stress plays an important role in the pathogenesis a most of diseases. Important components of protecting cells from oxidative stress are antioxidant enzymes, whose activity is genetically determined, due to the presence in the structure of the alleles of genes. Antioxidant enzymes are characterized by population and individual differences in enzyme activity. The study of genetic variation in the population of the world and the history of the formation of its gene pool is one of the promising areas of modern population genetics. Genetic variability of antioxidant enzymes in the body has recently become the most attractive destination in the pathogenesis of many diseases. Due to the involvement of enzymes in the pathogenesis of antioxidant enzymes social diseases is an important implementation. Comprehensive study of the genetic polymorphisms of genes contributes to the formation of human disease susceptibility. The antioxidant system is of the person a system that blocks the formation of free radicals, highly active oxygen. Under normal physiological conditions, a small amount of oxygen is constantly converted to superoxide anions, hydrogen peroxide and hydroxyl radicals. Excessive production of these radicals is a factor of injury; compensatory mechanism is the antioxidant system. The main component of this system is a network of antioxidant enzymes (AOP): superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT) and paraoxonase (PON). In this case, the activity of enzymes evolutionarily and genetically programmed to optimize the balance of oxidative processes and the activity of antioxidant defense systems. The purpose of the review is to summarize and discuss the current data on genetic polymorphisms of antioxidant enzymes in certain pathologies, the development of which plays the role of oxidative stress
