Authors: Simmi Patel , Sarah E Wheeler , Adam Anderson , Lisa Pinto , Michael R Shurin
Published: December 2022

Determining the extent of immunity induced by booster doses of COVID-19 vaccinations is crucial for informing recommendations for booster dose regimens as well as constant adjustments of immunization strategies amongst different groups of people within the population. The study involved 31 healthy volunteers (majority were healthcare professionals) who completed either vaccination course with Pfizer or Moderna mRNA vaccines and received a third dose of the vaccine. Here we report results on the evaluation of an antibody response to four different SARS-CoV-2 antigens: RBD, S1, S2 and nucleocapsid prior to third dose and two and four weeks after a booster vaccination. We detected a peak of high titers of antibodies after the third dose with a gradual decline after four weeks. No significant differences were seen between the two vaccines in terms of antibody response. There were no gender discrepancies between the two vaccines. Our results suggest that: third doses are necessary due to the emergence of different SARS-CoV-2 variants and postvaccination antibody testing continues be essential in determining possible standardization of SARS-CoV-2 vaccines regimens.

Published: December 2022

The focus of this study was to examine the effect of teaching based on inquiry-based learning versus traditional learning on mathematics achievement scores of undergraduate students enrolled in a college algebra class in a university classified as a Predominantly Black Institution. A college algebra course was chosen in this study due to the critical role it plays as a gateway for college completion and due to the generally high failure rate in college algebra. This study used a quasi-experimental design, with pre- and post-test to determine the effect of the instructional pedagogy on mathematics academic achievement of students. Analysis of covariance results from 41 students revealed, when controlling for college algebra readiness pre-test scores, students in the inquiry-based learning section showed significantly higher mathematics achievement post-test scores than in the traditional lecture section.

This study examined the hatchability performance of the offspring and some egg quality characteristics, which will be obtained from crossing Leghorn breed chickens and five different genotypes. The study's experiment was carried out in the XXXX . In the present study, which was designed to have one male and twelve females belonging to each genotype, a total of 200 eggs from each flock were examined. No adverse results were found in the incubation results of the crosses made with our local breed Denizli and Araucana, Brahma, and Cornish breeds, whose breeders increased locally. When egg quality characteristics were examined, the difference in egg weight between F1 genotypes was insignificant and ranged between 46.91-51.54 g on average. When the F2 generation was investigated, egg weight differed between genotype groups, and the average weights ranged between 57.6-67.14 g. In addition, the effect of genotype on strength, bark thickness, and point blunt up shell thickness values was significant. However, the effect on the Haugh Unit and yellow height were insignificant in the same generation. As a result, hybridizing genotypes with low yield performance with commercially important genotypes could provide a genotype for alternative production systems for future generations.

Anisotropy of the friction forces of rest and sliding frictionof single crystals of ice
Authors: Egorov B. P.
Published: December 2022

The properties of the ice of natural reservoirs are due to its crystalline structure. The dependence of the mechanical and strength characteristics of single ice crystals on the angle between the direction of application of force to a single crystal and the direction of its C-axis is known. Basically, this dependence is due to the possibility of the base plates of a single crystal of ice sliding relative to each other. In physics, in addition to the mechanical and strength characteristics of a solid, the properties of the surfaces of a solid state, manifested in the process of friction, are of great importance. The friction of two single crystals of ice relative to each other has been investigated in experiments on rest friction and sliding friction. From an artificially grown plate of a single ice crystal, samples of single crystals of ice with a certain orientation of the C-axis were made for the experiment. The measurement of the rest friction coefficient of a single ice crystal was realized according to the classical scheme of recording the minimum angle at which the single crystal began to roll down an inclined surface. The dependence of the rest friction coefficient of ice single crystals on the mutual orientation of the C-axes of single crystals relative to each other was discovered. The coefficients of rest friction in the case that the C-axes of single ice crystals are parallel to each other significantly exceed those obtained when the C-axes of single ice crystals are perpendicular to each other. Measurements have shown that the anisotropy of sliding friction increases with increasing initial velocity of the single crystal on the surface of the second single crystal. This is explained by the fact that with the growth of the path traveled by the M2 crystal, the time of interaction of single crystals of ice also increases, during which the properties of the anisotropy of single crystals of ice relative to sliding friction are manifested. Studies have shown the presence of anisotropy of the friction forces of rest and friction of sliding of a pair of single crystals of ice.

MODELING OF LOGISTICS STRATEGIES OF ENTERPRISES
Authors: VODOLAZHSKA T. , ACHKASOVA L.
Published: December 2022

The article provides a review and an extensive analysis of the latest literature, which highlights the latest developments and work of scientists in the theory of logistics, in particular, those whose object of research is the formation of logistics strategies of the enterprise. As a result of the consideration of a set of publications from various scientific sources, the need for the formation and selection of optimal logistics strategies as one of the ways of timely response to constant changes in a highly competitive environment, as well as preservation, strengthening and development of relevant competitive advantages, was established and substantiated. To facilitate and enable the implementation of such a choice, in particular, in conditions of market volatility, it is advisable to use modeling of such strategies. Therefore, at present, an urgent task in this field is to build a model for the selection of certain (optimal) logistics strategies, taking into account the key factors influencing it.
The main purpose of the article is to develop a model for choosing logistics strategies of an enterprise.
A careful analysis of scientific works devoted to the modeling of logistics strategies made it possible to formulate the following problems: firstly, the developed models of the formation/selection of these strategies are presented mainly in a rather general form, which necessitates their detailing; secondly, there is insufficient and/or partial description of the proposed models for choosing logistics strategies; thirdly, the indicators, on the basis of which the model for choosing a logistics strategy is built, need to be substantiated.
The study found that the logistics strategy is built on the basis of maximizing or minimizing certain key indicators that exert the greatest influence on its content. First of all, it is appropriate to consider the results of previous author's studies of certain aspects of the development of the logistics strategy of the enterprise as the basis for the selection and justification of the specified indicators, in particular: the clarified essence of the term “logistics strategy of the enterprise” and their improved classification.
A model for choosing the optimal logistics strategies of the enterprise has been built, whose key parameters are the logistics costs that outline the financial support of the strategy; the quality level of logistics service, which characterizes consumer satisfaction; the level of innovation, which determines the ability to quickly adapt and make changes in accordance with the latest trends and modern requirements in the logistics activities of the enterprise. Depending on the level of the specified parameters, a general set of logistic strategy options is outlined.

Authors: Strashok L.A. , Khomenko M.A.
Published: December 2022

The prevalence of obesity has reached epidemic proportions not only among adults, but also in the pediatric population. Expectedly the number of obesity-associated diseases, including non­alcoholic fatty liver disease (NAFLD) etc., increases, too. The pathogenesis of these conditions has common links, some of them are well known, others are being investigated. The latter include hormones of the gastrointestinal tract. They are considered as a part of the body’s humoral regulation. These compounds regulate energy balance of a body, and insulin resistance. It is assumed they can affect obesity and NAFLD pathogenesis.

Objective — to determine serotonin levels in adolescents with obesity and NAFLD.

Materials and methods. An examination of 108 adolescents aged 12—17 years with obesity (55 boys and 53 girls) was carried out. The control group consisted of 32 healthy adolescents (18 boys and 14 girls). Depending on the hepatobiliary pathology all patients were divided into two groups: 1st group included 29 (26.9 %) adolescents with functional disorders of the biliary tract (FDBT), and 2nd group consisted of 79 patients (73.1 %) with NAFLD and FDBT.All patients underwent a comprehensive clinical and anamnestic examination, clinical and biochemical blood tests, including determination of the levels of γ-glutamyl transpeptidase (GGT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), total bilirubin and its fractions, triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), very low-density lipoprotein cholesterol (VLDL-C), atherogenic coefficient (AC) value. Levels of fasting glucose and immunoreactive insulin (IRI), HOMA-IR index, and blood serotonin level were also determined. An ultrasound examination of the abdominal cavity was performed.

Results and discussion. According to the clinical and anamnestic data, there were no differences between the groups of adolescents with obesity, depending on the existing hepatobiliary pathology, except for a higher value of the WC/Height in patients with NAFLD and FDBT (p < 0.01). The results of laboratory investigations demonstrated that in patients with NAFLD and FDBT, compared to patients with FDBT, the following parameters were higher: fasting glucose level (p < 0.05), IRI (p < 0.01), the value of the HOMA-IR index and the frequency of its increase (p < 0.01), levels of ALT and AST activity (p < 0.05), the levels of triglycerides and VLDL-­C (p < 0.05). The level of serotonin was higher in the group of patients with NAFLD and FDBT compared to the control group (p < 0.015).

Conclusions. Adolescents with obesity, accompanied by NAFLD and FDBT, had higher rates characterizing abdominal obesity, carbohydrate and lipid metabolism, liver enzyme activity compared to patients with FDBT. Serotonin levels were higher in the group of patients with NAFLD and FDBT compared to the control group.

The article analyzes the role and importance of education system in human capital development in modern society. It is argued that education is the basic factor on the basis of which resource potential is formed and functions, a component of which is human capital. Education is not just a source of future socio-economic growth of the country. Its function is not only general intellectual and professional training, but also the general spiritual parameters of human activity, human cultural capital and its subsequent development. Skills and knowledge acquired at different stages of training increase the effectiveness of further investment in human capital, as a result, provide the opportunity for successful activities in various areas of society. In the process of realization of human capital there is an increase in labor productivity, quality of life of the population, overcoming the existing social differentiation between different social groups and ensuring sustainable socio-economic progress of society. Based on statistical materials and the results of sociological research, the main trends and contradictions in the development of the educational system in the region are determined on the example of the Republic of Bashkortostan. The article substantiates the necessity of developing social program, aimed at solving the problems of increasing the efficiency of using education as the most important factor of human capital development and its influence on intensification of development of different spheres of life activity of society, regions and country on the whole.
MICROBIAL COMMUNITIES OF KARST CAVES

Special geochemical, hydrological and microclimatic conditions in karst caves lead to the development of unique bacterial communities in them. The microbiota of such communities has complex, often unique mechanisms of interaction, which currently does not allow us to fully identify their species composition. Among the bacteria in caves, the most common are representatives of Alfaproteobacteria, Betaproteobacteria, Gammaproteobacteria and Actinobacteria. Lack of light, lack of nutrients and low temperatures lead to a number of adaptations in bacteria, such as a decrease in cell size, slow metabolism, changes in membrane lipids and enzymes, and a number of others. In aphotic conditions, the basis of trophic chains are chemolithotrophic bacteria. The development of bacteria occurs mostly on the surface of mineral formations, soil, walls and in the upper layer of water. Rocky surfaces of caves represent the largest areas potentially suitable for colonization by microbial communities. There is a widespread assumption among researchers that the bacteria living on the walls are mostly cave microbiota and are the least susceptible to changes under anthropogenic load. Bacteria are actively involved in the geochemical transformations of the environment: corrosion of rocks the subsequent deposition of mineral formations. At present, the hypothesis of biogenic mineralization is generally accepted. On the one hand, crystal formation occurs with the participation of only living microorganisms, on the other hand, a change in the physicochemical conditions of the environment is of no small importance in this process. A significant role, according to researchers, is played by secreted extracellular substances that induce passive mineralization or, conversely, cause the dissolution of calcite. In addition, it is known that microorganisms isolated from caves, while remaining viable, after some time lose their ability to form or destroy mineral formations. Bacteria involved in the transformation of mineral substrates are not confined to taxonomic groups and act as part of multispecies communities.

During early postnatal adaptation, the equilibrium between pro-oxidant and antioxidant systems of the organism is unstable. The birth and switch to pulmonary respiration initiate a cascade a free radical reactions and leads to an excessive load on the antioxidant protection (AOP). Functional immaturity of AOP, caused by the intrauterine growth retardation of the embryo and fetus (IUGR), can lead to oxidative stress. In humans, these processes are well-known, but in animals, they are under-studied. Experiments on Simental calves ( Bos taurus taurus ) with IUGR (Group I, n = 30) and physiologically normal pregnancy in their mothers (Group II, n = 29) aimed to evaluate AOP (catalase activity, glutathione peroxidase (GPO) activity, superoxide dismutase (SOD) activity, concentrations of vitamin A, alpha-tocopherol, and L-ascorbic acid) and oxidative stress parameters (concentrations of malondialdehyde (MDA), diene conjugates (DC), and their ratio) in the blood 1, 7, 14, and 28 days after the birth. Laboratory tests were performed with spectrophotometer UV-1700 (“Shimadzu”, Japan). Statistical analysis was performed in IBM SPSS Statistics 20.0 software (“IBM Corp.”, USA). The authors used the MannWhitney U-test to reveal the differences between the samples of calves of the same age. Wilcoxon's test for paired data was used to evaluate the dynamics inside a group. The blood of neonate calves with IUGR showed increased activity of catalase (by 30.3%, p < 0.05), SOD (27.8%, p < 0.05), content of vitamin A (by 33.6%, p < 0.05), alpha-tocopherol (by 33.9%, p < 0.05), and L-ascorbic acid (by 47.4%, p < 0.05), elevated concentrations of MDA (by 29.9%, p < 0.05), DC (by 4.5%, p < 0.05), and the ratio of MDA/DC (by 26.6% (p < 0.05), respectively, in comparison with animals from Group II, which indicated functional insufficiency of their AOP. The dynamics of the content of MDA, DC, and the ratio of MDA/DC in the calves blood on days 1-28 of their life showed a decrease in the functional capacity of AOP and more intensive transformation of primary ROI into intermediate and final toxic products considering the age of animals.

The article deals with the problem of discussion by the population of Bashkiria of the draft Model Charter of the collective farm, which took place in April - October 1969, and the introduction of various proposals and comments to it. A brief analysis of the literature indicates that this problem remains poorly understood. At the same time, modern historiography, including local historiography, actively studies various forms of relations between the government and the population. According to the researchers, the "discussion" of various draft laws and decrees, the "introduction" of their own proposals and comments to them were among the forms of "dialogue" of citizens with the authorities at that time. The work uses messages published in the republican newspaper "Soviet Bashkiria"; unpublished letters from readers received by the editorial office of the central publication "Rural Life"; citizens' proposals recorded in the party documents of the Bashkir regional Committee of the CPSU. The use of several types of sources allows you to achieve a certain degree of objectivity, however, they do not represent the full picture. The specific proposals made by citizens allow us to find out the level of socio-political activity, the development of public interests and preferences of the population of the republic during this period. In the discussion of the draft law, the population of Bashkiria was less active compared to neighboring regions. It is concluded that the proposals made were sometimes quite contradictory. On the one hand, some of them concerned the further improvement of social protection, social status, remuneration of collective farmers and pensioners, on the other, they demanded stricter Soviet legislation in the field of personal subsidiary farming, labor discipline. Thus, there were proposals on the need to include all collective farmers in trade union organizations, increase pensions, etc. Citizens were concerned about the lack of collective farm democracy, some advocated greater restriction of personal subsidiary farms. However, in general, the proposals made by the commission were not taken into account. The significance of the amendments to the draft law is that they indicate an increasingly increasing political activity of the population, including rural ones, and their interest in the political and socio-economic events of the era.

The need for a qualitative update of the characteristics of labor capital in the conditions of digitalization of the region's economy is due to the search for the necessary opportunities for accumulation and use of human potential, preservation and prolongation of the life cycle of labor resources. The modification of labor capital is expressed in increasing the role and transformation of the qualities of an employee not only as an object, but also as a subject of the labor process, changing its characteristics and socially responsible orientation. The purpose of this study is to analyze the process of qualitative renewal of the characteristics of labor capital in the conditions of digitalization and socialization of the economy of the region, to identify the main prerequisites, determinants and factors of its modification. The study revealed the causes and factors of qualitative renewal of labor capital in the conditions of digitalization and socialization of the economy, including: improvement of the structure of labor capital, development of social factors of the organization, improvement of working conditions, development of labor and social activity. The main characteristics and sources of labor capital development are identified: educational and professional level, health and professional longevity, sanitary and hygienic conditions and a healthy production environment, labor and creative activity, social responsibility and participation in management. The authors determined that the qualitative renewal of labor capital is determined, first of all, by changes in the structure of organizations and working conditions, the type and characteristics of employees, the role of the collective in creating economic wealth, social progress and is expressed in increasing the role of the employee's personality, changes in his socially responsible orientation. The active participation of personnel in production management is an important element of the humanization of social and labor relations and the modification of labor capital. Innovations in labor and employee characteristics are due to the requirements for personnel from modern advanced generations of labor tools, innovative technologies, and digitalization of the economy. Modern innovative production and digitalization of the economy require constant professional development. In addition, there is a need for competent employees with better professional abilities. The human factor is turning into the main source and impetus of economic and social development.
THE SOCIAL CAPITAL OF THE FOSTER FAMILY AS A TECHNOLOGY OF LIVING SUPPORT FOR ELDERLY PEOPLE IN THE REPUBLIC OF BASHKORTOSTAN

The article discusses an innovative and effective form of housing for the elderly and disabled in a foster family in the Republic of Bashkortostan. The experience of organizing a foster or substitute family is developed in a number of European countries and the USA. It has been established that this technology provides an elderly person with the necessary care and living conditions, leisure activities, psychological support, and for a foster family - additional financial support, especially in conditions of declining living standards and impoverishment of the population. The creation of the institution of a foster family for the elderly as an innovative form of their life arrangement will significantly improve the quality of life of older citizens, change their “social well-being”, relieve them of the problem of loneliness, strengthen the connection between generations, and contribute to the development of the family institution. In Russia, in order to solve the problems of older people, in 2004, the project "Foster Families for Elderly and Disabled Citizens" was launched. The mission of this project is to organize public support, help with household chores, and provide social and psychological services to lonely needy citizens. Particular attention deserves the peculiarities of organizing foster families for the elderly and disabled in the regions of the Russian Federation. Most of the regions supported the initiative of the project and many of them have their own experience in implementing this social technology. Each subject has its own characteristics and differences in the creation of foster families for the elderly, which is associated with the presence of its own legislative framework for the implementation of this project. The Republic of Bashkortostan has its own positive experience in the implementation of the designated social program. Social services provided by stationary and semi-residential social service institutions will not be able to replace the usual home family care for the elderly. It is possible that in the future the foster family model will replace special stationary social service institutions for the elderly. The solution of social, social, psychological and other problems of the elderly requires more active participation of the potential of the family institution, a constant search for effective forms and technologies of social services.
