Physical fitness is considered as a process of directed development of physical qualities, contributing to the formation of the necessary range of motor skills and abilities. The study of students’ physical fitness was conducted by gender. Physical fitness testing was carried out according to the guidelines developed by the Ministry of Education of the Republic of Belarus. The study of physical qualities showed that the maximum increases of the indicators of physical fitness being studied do not always coincide with the rates of puberty, however, in general, the biological development of adolescents is determined by gender differences in the dynamics of physical fitness. An integral assessment of the general physical fitness of schoolchildren showed that students of all age groups, regardless gender, are at the average level of physical fitness when they are involved in sports.

The goal of this work to evaluate the efficiency of using a hiphop class method during the educational process of non-sports university female students based on lateral dominance indicator manifestation. One of the most important evaluation parameters of brain hemispheres activity is lateral organization profile presence or absence. Brain lateralization is manifested as a consequence if the brain hemispheres functional asymmetry occurs. Unequal distribution of brain strain on the brain hemispheres’ activity is one of the obvious reasons of both motor and sensory asymmetry occurrence among those, who go in for physical training and sports. This is connected with unilateral character of the training process in sports and in physical training educational process. In the course of pedagogical testing of non-sports university female students, functional motor asymmetry with an individual right-hand type of the lateral profile has been revealed. This fact emphasizes insufficiency of impact on one of the coordination skills indicators in the process of physical training classes with students, which aggravates the processes of brain hemispheres functioning, which, in its turn, leads to inferior development of psychomotor qualities, which manifestation level is directly connected with coordination skills. As a result of the pedagogical experiment, based on using hip-hop as a means of coordination skills refinement, experimental group showed reliable improvement of lateral dominance indicator towards its decrease.

The article examines the issue of voluntary behaviour as a process aimed at personality development that contributes to the formation of skills necessary for learning at school. Voluntary behaviour manifests itself in various aspects of a child’s life, including play activity. Playing children learn to regulate their behaviour. Games with rules acquire a special role, using game rules children have to act purposefully and overcome difficulties in solving a game task. The study of the level of voluntary behaviour development in senior preschool children was carried out using diagnostic techniques. The results of the study showed that at the beginning of the research the pre-schoolers had low indicators of voluntary behaviour. Therefore, a complex of outdoor games with rules was selected for voluntary behaviour development in senior pre-schoolers since they contain a number accompanying conditions that increase voluntary behaviour.

One of the ways to enrich food with essential micronutrients is to use cereals and legumes. The inclusion of wheat germ in the daily diet is the basis of “correct” and “healthy” nutrition systems. One of the most promising ways to create food products with desired properties is the use of a computational method for optimizing the amino acid rate of finished foods. By correctly selecting the component and nutrient composition, it is possible to produce food products for functional, specialized and therapeutic and prophylactic nutrition. Only by using of modern software you can quickly select and adjust the diet for various population groups, taking into account national and regional characteristics. The digitalization of world markets provides prerequisites for the creation of many newest software products that help technologists in the development of recipes for functional and preventive food products, raising food production to a new quality level.

This applies in particular to the Syrian Arab Republic and the Tartous governorate located in the eastern Mediterranean. In the article the factors determining tourism demand in the Tartous governorate are studied. The results of the investigation allowed formulating recommendations for the development of tourism in Tartous governorate.

Purpose: The purpose of our research is to determine, on the basis of mathematical processing of the experimental results, the most informative functional test, which makes it possible with a greater degree of reliability to assess the state of the vestibular apparatus and the presence of deviations in the work of the nervous system of students of higher educational institutions, and thereby recommend it for use in the practice of physical education in higher educational institutions. Results: Data analysis of the ascertaining experiment for evaluation of the condition of the vestibular system and possible nervous system disorder of the undergraduates shows a significant difference in functional test indicators which makes it necessary to choose the most informative one. Considering the comparison of the test results according to the normal distribution law and further calculation of variation coefficient of the received data it was defined that Romberg test example assuming to hold the balance standing on one leg with eyes closed with hands upwards is the most informative test allowing to more exactly define the condition of the vestibular system and nervous system of the undergraduates. Conclusion: Practical application of functional tests in physical training of students and interpretation of received data regarding the actual biological age of students allows us to actualize their need in physical activity increase. Herewith it is necessary to rely on results of the most informative functional tests, which do not require the application of complex measuring equipment and are quite simple in calculation of results.

The paper describes the features and components of the academic course content and teaching techniques aimed at forming the pedagogic position (a set of pedagogical knowledges, skills, competences, values, and attitudes) of a doctor in young resident physicians. This position contributes to an effective health-oriented lifestyle dissemination and adoption, especially in patients with chronic diseases. It reflects a new perception of physician’s vocational duties, including care for patients’ life and their need for psychological support. Biopsychosocial approach to health and disease was chosen as a conceptual core of the academic course content and methodology design, specially elaborated to unite pedagogical aspects of the physician’s job with the clinical ones. The set of methods aimed at doctor’s pedagogical position formation and development of professional reflection, values and attitudes included lecturing, interviewing, case studies and clinical cases analysis, discussion, questionnaires, brainstorming, trainings and testing. Eighty-six resident physicians were observed within this study. Such components of the pedagogic position as knowledges, skills, attitudes and motivation showed more dynamics, whereas personal traits were seen as a more static and stable component of the pedagogic position in resident physicians. A remarkable divergence of progress was elicited between doctors of various specialties.

The article presents the issue of monitoring the sociopsychological state of society in the period of epidemics by means of neural network algorithms and methods. Publications of sociologists, psychologists, and philologists, who have created a number of methods for in-depth analysis of emotions and tonality of texts in the Internet media, including cognitive and interpretive decoding, are devoted to substantiating approaches and methods for studying the content of Internet content. The purpose of the study is to substantiate the methods and computer tools for studying the socio-psychological state of society in crisis situations, in particular epidemics, based on neural network technologies based on Internet resources. The article considers methodological approaches and particular methods of their computer implementation. It is shown that for the computer analysis of the psychological state of society in the context of the epidemic, it is necessary to adapt the methodology for designing neural network technologies, as well as systems for collecting and textual analysis of the content of electronic and Internet resources. An effective approach to creating such systems is embedding, which uses a dense vector representation of tokens in a multidimensional space, the dimension of which should be selected experimentally in the process of training and testing the developed artificial neural networks (ANN). For contextual neural network analysis, a multiclass-oriented ANN with regularization layers of the form “SpatialDropout1D”can be used. The neural network architecture can be built on fully connected layers with an activation function of the “ReLU” type. The scientific and applied significance of the results of neural network analysis based on Internet resources is the possibility of obtaining classified assessments and segmentation of target information about the psychological state of society during periods of epidemics. This information can be used to effectively counter information threats to society.

The COVID-19 epidemic, which turned into a pandemic, has led to the introduction of lockdown in many countries as a measure to prevent the spread of the virus. Significant changes have occurred in the lives of Russian students. The research objective is to study students’ strategies of adaptation to the self-isolation caused by the need to prevent the spread of COVID-19. To achieve this purpose, an online survey of students was conducted, followed by a correlation analysis of the data. The survey involved 269 students aged 17-21. In self-isolating conditions, students prefer to use strategies aimed at self-change. Two groups of strategies are distinguished in the structure of students’ adaptive behavior, between which there are positive correlations of average strength. The first group includes students’ preferable behavior strategies (accommodating, self-change, and self-immersion). The second group consists of strategies that are not popular among students (environment changing, waiting, avoidance, and passive self-representation). Male students are more active in solving problems than female students. The research results expand the existing understanding of students’ reactions to changes related to self-isolation. They can be useful to teachers, psychologists involved in assessing the social consequences of the COVID-19 pandemic on students.

The research touches on an interesting and important, both theoretically and practically, scientific problem that lies in the contradiction between two circumstances. The first circumstance is the large number of the Russian dissertations on judo. And the second circumstance is the lack of that scientific information, the knowledge of which would determine a significant increase in the sports’ achievements of Russian judokas. In the whole the elimination of this contradiction is necessary for the integrated management of increasing the competitiveness of the sports’ achievements of Russian judokas. In addition, the solution to this contradiction is also relevant in the context of the fact that full knowledge about the judo’s phenomenon, about judo as a weapon and about the ways of judo’s mastering is available mainly to the Japanese as the judo’s founders. The purpose of this research is to clarify the promising directions of the Russian dissertations on judo as a theoretical and methodological basis for increasing the effectiveness of Russian judo on the world sports’ arena. The methods of this research: comparative method, case studies, content’s analysis, frequence’s analysis, conjugation’s tables’ analysis, genetic method, theoretical modeling. The results of a systematic analysis of all Russian dissertations on judo (for the entire period over forty years) are presented, the composition of these dissertations and significant relationships between their main characteristics are uncovered, gaps in scientific knowledge in judo are identified, and the necessary directions for further dissertational researches in this area are outlined.

The article examines the concept of such an activity as “sports tourism.” This category is considered both as a type of tourism and as a type of sport. The authors formulate their definition of the concept of “sports tourism” and consider the difference in approaches to the definition of sports tourism by Russian and foreign scientists, proposing to understand sports tourism as a temporary departure of a traveler from their home destination for the purpose of active or passive participation in activities, in one way or another related to sports. Problems in the development of sports tourism in the Russian Federation are formulated, to which the authors attribute its poor infrastructure, lack of state support, inaccessibility of some destinations and lack of dedicated specialists.

Main food products of Russians are cereals, various meat and fish. The phenomenon of Russian and another national cuisines are balance of main nutrients in their dishes. Traditional Russian dishes are different kinds of porridge and culinary products made of cereals. Grits themselves are the source of protein, carbohydrates, lipids, fiber, vitamins of B group, biologically active substances and minerals but unbalanced grain protein in amino acid content is considered to be a serious deficiency. There is the lack of lysine, threonine, tryptophan in the majority of grains, so vegetable protein is digested and processed harder than animal protein. That is why, while developing compositions of dishes, it is necessary to consider availability and digestibility of the protein. Level of digestion of protein can be estimated during the process of digestion of food products by the system of ferments in vitro. In this work you can see the results of the research of amino acid composition of protein and their hydrolyzates after enzymatic hydrolysis in boiled grains. It can be seen that hydrolyzates have bigger coefficient of utilized protein and lower percentage of unutilized protein comparing with untreated grits. According to these results they developed two-, three-, four-component compositions from buckwheat, barley, oats and millet grains and elaborated more than 100 optimal compositions of dishes from grains.

The purpose of the research is to identify the role of physical culture and sports activities on the practice of students’ self-preservation behavior. The materials: The research was based on an online questionnaire which was held among 2503 students in REU Plekhanov (Moscow) in October 2019 under E. V. Kargapolova leadership. The results: The most common practices of self-preservation behavior are walking outside, physical education classes and regular sports. The most preferable kinds of sports for students were football, basketball and volleyball. The less preferable were Eastern health practices. Nevertheless, only half of students were regularly engaged in physical education activities. Most of respondents consider they are able to make a set of training exercises and a rational diet. Conclusions: There are several contradictions in students’ behavior values of self-preservation and their practices of sport activities. The majority of respondents understand the importance of a healthy lifestyle. Nevertheless, students do not always follow these practices in their daily routine. There is a strong correlation between their health and regular sport assessment, especially. This was due to the presence of a physical education system in higher educational institutions. That’s why universities are the most important platform for sports activities.

The article provides a histological description of the internal organs – the spleen and kidneys of chickens exposed to the action of “Guidamis” as an adjuvant. A lysate was tested as part of a sample of the vaccine PB-07 against infectious bronchitis developed by researchers of the Department of Virology and Tumor Diseases of Birds of the Russian Agricultural Academy (Lomonosov). The experiments were carried out on Lohmann Brown chickens in the conditions of the Laishev branch of “Ak Bars” Poultry Company, the Republic of Tatarstan. The prolonged action of the vaccine against infectious bronchitis and the use of “Guidamis” as an adjuvant was manifested as an increase in the proliferation and differentiation of lymphoid tissues in the numerous lymph nodes. The use of the vaccine and the adjuvant had a weak reactogenic effect. In the spleen of control chickens, hyperplasia of lymphoid tissue cells is weakly expressed. In the periarterial zone of nodules of the thymus-dependent lymphocytes, the cell density is low. In the kidneys, for fourteen days after the vaccination against infectious bronchitis using Guidamis, the moderate granular dystrophy of the epithelium, mainly of individual distal tubules, and local moderate manifestations of edema of the capsule of the renal corpuscles were observed. In the kidneys, signs of pronounced edema of the capsule cavity, significant disturbances in the patency of the tubular network caused by swelling and partial desquamation of the epithelium, as well as the presence of epithelium and protein mass in the lumen of the tubules, were observed.

The object of the study is a double disc coulter with a pressure plate. The aim of the research was to simulate the operation of the double disc coulter using a grain seed drill as an example. Analytical dependencies for determining the traction resistance of the improved coulter are presented. The method of calculating the drag resistance of a double disc coulter with an original pressure plate installed on it is given. The components of the traction resistance balance have been determined and the dependence on the sowing depth has been established. 3D graphical dependences of the traction resistance of serial and advanced coulters on the speed and depth of its movement have been constructed based on the results of calculations. The main influence is the placement depth. Speed of movement of the seeder in the considered interval of its values does not render essential influence on traction resistance. Installation of an additional pressure plate increases traction resistance to 5 %.

The possibilities of adaptation of Begonia grandis Dry., the most cold-resistant representative of the genus, to conditions of the forest-steppe zone of Western Siberia, more severe than in areas of natural growth in China, are studied. The experiment carried out outdoors in spring-summer-autumn period in comparison with a year-round greenhouse cultivation. It was established that the development of plants placed outside the greenhouses accelerates: the flowering time was reduced by 1.5 times and fruiting began two months earlier. The productivity indicators increased such as the number of simultaneously blooming inflorescences, the number of female flowers in separate inflorescence and the number of ripened fruits. The coefficient of vegetative propagation also increased. The number of bulbils was almost 2.5 times more, with significant increase in their size. It was shown that plants of B. grandis grown in the open air were adapted to the conditions of the forest-steppe of Western Siberia. By the time of autumn frosts, they are completing flowering, form ripen seeds and bulbils. Thus, reproduction is provided both by seed and vegetative means. However, to undergo the full life cycle of B. grandis it is necessary to keep dormant tubers in greenhouse or shelter during the frosty period.

The scientific research is dedicated to studying of treatment problems of mesial malocclusion with the anterior mandible shift among preschool aged children (in the period of temporary dentition). The point of the study is to demonstrate the effect of treating mesial malocclusion associated with the mandible anterior shift and reverse overjet in a clinical case description. During the research of a clinical case long term results were analyzed. The method of treating mesial malocclusion associated with the mandible anterior shift and reverse overjet included usage of the original appliance. The appliance was also supposed to lead to harmonic development of a child’s oro-facial area. The analysis showed advantages of the suggested original orthodontic appliance. The malocclusion was corrected in a short time (3 months), that let us develop physiological jaws and teeth arches relationships and to resolve mandible side shifting before the central incisors erupted. During the eruption permanent incisors take their place and establish the proper overjet, that creates physiological conditions for harmonic oro-facial development. The result is stable over time. The appliance is easy to use and to adapt by children and has a good fixation in oral cavity. Thus, the suggested orthodontic appliance could be recommended for treatment of mesial malocclusion associated with the mandible anterior shifting among preschool aged children.

The article presents a comparative analysis of the effectiveness of the use of finite elements of various dimensions in the study of the stress-strain state (SSS) of objects of the agro-industrial complex (AIC). To determine the strength parameters of the AIC objects, which can be attributed to the class of thinwalled, it is proposed to use a two-dimensional finite element in the form of a fragment of the middle surface of a triangular shape with nodes at its vertices. To improve the compatibility of a two-dimensional finite element at the boundaries of adjacent elements, it is proposed to use the Lagrange multipliers introduced in additional nodes located in the middle of the sides of the triangular fragment as additional unknowns. It is proposed to use a three-dimensional finite element in the form of a prism with triangular bases to study the SSS of agricultural objects of medium thickness and thick-walled. To improve the compatibility of the prismatic element, Lagrange multipliers in the middle of the sides of the upper and lower bases are also used. On the example of calculating a fragment of a cylindrical pipeline rigidly clamped at the ends loaded with internal pressure, the effectiveness of the developed two-dimensional and three-dimensional finite elements with Lagrange multipliers was proved. The validity of the use of a twodimensional element for researching the SSS of agricultural objects belonging to the class of thin-walled was proved.

The paper analyzes the regional statistical characteristics of analytical and morphometric properties of agro-gray soils formed in one-factor conditions of the Privyatskaya band of the Pre-Kama region of the Republic of Tatarstan.

The upper part of the soil profile of the studied soil has a low humus content, medium acid reaction, the profile distribution of the sum of absorbed bases is almost uniform and is in the range of 22.6 to 26.8 mmol /100 g of soil. Generalization of the accumulated analytical and morphological information is a zero cycle of monitoring of arable soils and can serve as a reference for comparison to identify changes in the properties and morphological structure of arable soils in the region. In conditions of intensive agriculture, statistical parameters make it possible to purposefully manage soil fertility in the studied region.

This work is aimed at studying the influence of various components’ content on the process of vacuum dehydration. It was found that with an increase in the proportion of fat in dry matter from 10 to 20 %, the duration of disinfection increases by 4 %. The further grows of the fat proportion from 20 to 50 increases the process duration by 54 %. It was revealed, when cheeses, with the fat proportion equal from 10 to 50 %, a change their fat proportion by 1 %, the duration of dehydration decreases by 4.25 minutes, and the drying rate grows by 0.0065 %/min. It has been discovered that with an increase in the table salt concentration with the same mass fraction of cheese moisture 53–55 %, a decrease in the rate of dehydration is observed as well. In the period with a constant drying rate at a concentration of sodium chloride of 1 %, the drying speed is 0.98 %/min; 2 % – 0.8 %/min; 3 % – 0.72 %/min; 4 % – 0.54 %/min. The amount of water activity in cheeses was investigated. It was established that with an increase in the concentration of table salt from 1 to 4 %, the water activity of cheese before drying changes by 0.131; after drying – by 0.174.

Selais fish is difficult to discriminate with other Silurid fish species based on morphological characters. As a result, the valid species of selais fish is uncertain. Therefore, a molecular phylogenetic study was needed to clarify species boundaries and to addresses genetic relationships of the selais fish. In this study, 16S mitochondrial gene of ten selais samples collected from Arut River (Central Kalimantan) were sequenced, from which a Bayesian trees was generated. Result revealed monophyletic of selais fish which is revealed as a single species. The Bayesian inference showed that the selais fish clade is distinguished with two other genus, Kryptopterus and Ompok, by its sequence differences. This finding can address species boundaries of selais fish using Bayesian approach, but the name of the selais species has not been clarified.

Optimization of plants long-term conservation under in vitro conditions and identification of their structural and functional features during preservation is the basis for the creation of a genebank of cultured and wild plant species in vitro. The aim of our work was to study morphological and anatomical features of plants in lavender cultivar ‘Sineva’ after two years of in vitro storage at low positive temperatures. The plant material was evaluated after 24 months of conservation. A significant decrease in the linear parameters of leaves in the preserved plants was noted. Leaf shape altered from narrowly linear to oblong. With prolonged storage, the thickness of the leaf blade slightly increased. The integumentary tissues were thinner, compared with the plants cultured under standard in vitro conditions, the cuticle was not clear. The number of stomata decreased. The number of small vascular bundles decreased. The obtained data demonstrate viability of in vitro preserved explants, despite significant differences in structure, preservation of chlorophyll-containing tissues, a decrease in transpiration, and an increase of trichomes number. The stability of the vegetative organs functioning was revealed.

The article provides an estimation of abundance the typographer bark beetle using barrier traps in the spruce forests of the Republic of Tatarstan. For the last 10 years, there has been the shrinkage of spruce forests throughout the Russian Federation due to adverse factors, primarily the weather. In the forests of the Republic of Tatarstan, the main reasons for the unsatisfactory condition of forest stands are forest diseases – 20,276.7 ha and weather conditions – 16,824.1 ha, corresponding to 51.7% and 42.9% of the area of all plantations with disrupted and lost stability. The research studies were carried out in the “Sabinskiy Forestry Enterprise” and “Lubyankskiy Forestry Enterprise” of the Republic of Tatarstan. According to our observations for the whole growing season, the largest number of beetles is concentrated on a site of pure plantings at the age of 40 years and is estimated at 1,645 pcs. On all three sites, the peak number of beetles takes place on July 5, 2019 corresponding to 3,684 pcs. In 2019, there was damping of some foci of this pest on 330.1 ha. At the same time, the new foci were identified, which accounted for 9.5% of the total area of bark beetle foci. As a result, at the end of 2019, the total area of foci of this pest in the forests of the Republic of Tatarstan was 1,018.9 ha, which is 28% less than the same indicator last year.

The results of studies of the chemical composition of atmospheric air showed that the concentration of ammonia (0.2520 mg/m3), nitrogen dioxide (0.3942 mg/m3) and hydrogen sulfide (0.0269 mg/m3) exceeded the MPC requirements. The seasonal dynamics of the spread of aerogenic pollutants revealed a decrease in NO, NO2, H2S, SO2from winter to the spring-summer season. However, the content of such pollutants as NH3, CO and dust increased significantly in summer to 0.0816, 3.7140 and 0.0289 mg/m3respectively. During bio-indication of 363 trees only 4 species of the 16 studied ones were characterized as healthy (KAcer Platanoides) to environmental pollution (the level of asymmetry in the transport zone was 0.039 against 0.077–0.078 in the silver birch (Betula pendula) and the fragrant poplar (Populus suaveolens). The high level of anthropogenic pollution in the transport zones of the city adversely affected roadside biotopes. It has been proven that roadside phytocenosis is significantly sparse and the population density drops sharply by 50–100 %, compared to cleaner functional areas. The results of lichenoid indication showed that in most of the sites studied, the air was highly polluted (pollution class 1) and the concentration of SO2was 0.10–0.30 mg/m3.

In recent years, there is a growing number of children with speech disorders, including General speech underdevelopment (GSU). GSU children have problems with communication, development, and difficulties in working together with their peers. The use of kinesiological exercises complex in correctional and developmental work with preschool children is effective for the development of coherent speech and optimization of interpersonal relationships in the children’s team.

The scientists of the Volgograd State Agrarian University and Samara State Agrarian University carried out research on the use of bio-soluble silicon form as a part of the «NaBiKat» additive in various concentrations in the rations of pullets and egg-laying hens in conditions of the Volgograd region at the facilities of Volzhskaya Poultry Farm CJSC in 20152019. For the experiment, the birds were selected by the method of similar groups (control and three experimental). The control group poultry received a standard ration; the additive was additionally added to the feed of experimental groups 1, 2 and 3 in a concentration of 0.12%, 0.15% and 0.17%, respectively, depending on the fodder weight. The digestibility of dry matter in the body of young and adult laying hens was higher in the experimental groups compared to the control, by 1.82% and 1.79%, 3.13% and 3.08%, 1.97% and 1.93, respectively. The use of the silicon-containing polyadditive “NaBiKat” in various dosages contributed to the increase in pullets’ live weight by the end of the experiment by 4.15–4.35%, and to egg productivity of hens by 0.56% -1.37%. At the same time, there was a decrease in costs for a dozen eggs and 1 kg of egg mass.

The article presents a multi-year multicenter research material concerning the study of adaptive aspects of hemodynamic and vegetative homeostasis of athletes engaged in football and hockey at the stage of sports improvement. The following was revealed: both groups of athletes were characterized by the formation of a cardiovascular functional system with a state of minimal tension of regulatory mechanisms to maintain hemodynamic homeostasis. The total sum of ICVR indicators in the group of football players was -1 point, which, according to the classification, can be assessed as a state of some functional tension, manifested by the mobilization of protective mechanisms. The hockey players were observed to have an optimal state of the regulation systems tension. It is characteristic of a satisfactory adaptation of the body to environmental conditions (1 point). The vascular type of self-regulation of blood circulation is more optimal in the formation of adaptation to dynamic loads of variable intensity.

The composition of anthocyans depends on both the variety and the grape habitat. The presence of 3.5-diglucosides in hybrid varieties was established.

Currently, there are a lot of applications of vortex technologies. The vortex effect is used in gasdynamic cold generators and vortex cooling chambers. Vortex devices are also used as dehumidifiers, separators, for cooling and heating hydraulic fluids, separating two-phase media, gas mixtures, evacuating, etc. Scientists study the applicability of vortex equipment for traditional and freeze-drying of agricultural products. However, the influence of geometric parameters of vortex devices on the productivity and energy efficiency of temperature separation of gas flows is poorly studied. Research aimed at finding opportunities and expanding the field of application of vortex tubes is an urgent task. The paper describes twodimensional and three-dimensional mathematical models of the swirling gas flow arising in a vortex tube. It presents results of its implementation in the Anсs-Fluent software package. Thermodynamic and hydrodynamic characteristics confirm the effect of temperature separation in a vortex tube. The dependences of temperature separation on the swirl angle and inlet pressure were obtained. For a two-dimensional vortex tube model, calculations were carried out using various turbulence models. The influence of the cross-sectional area at the hot gas flow outlet on temperature separation was studied.

Anterior disc displacement is a condition when the articular disc is in the anterior normal position. Epidemiological research shows that the prevalence of TMD is higher in women than in men. Women have a dominant hormone that is not owned by men, the hormone estradiol. Estrogen receptors and the hormone progesterone are found in articular joints in humans. Joint structure, extracellular matrix remodeling, and bone volume modification can be affected by sexual hormones. It was thought to cause changes in connective tissue in the TMJ structure. This study aims to determine the effect of the level of the hormone estradiol in menopausal women on anterior temporal disc displacement of the temporomandibular joint. Subjects were 40 postmenopausal women who were examined for temporomandary joints. The diagnosis of anterior disc displacement was made using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD) method. Subjects were grouped into subjects with normal tempromandibular joints and subjects with anterior disc displacement. Estradiol hormone was examined by the immunoassay method. This study’s conclusion is estradiol hormone in menopausal women with anterior disc displacement is higher than menopausal women without anterior disc displacement.

The morphological characteristics of Phlomoides oreophila, which grows in the Altai Mountains and Southeast Kazakhstan, are given. It is established that the species belongs to the monopodial-rosette model of shoot formation. The main structural unit is a perennial basal (skeletal) rosette shoot. Its annual growths form an epigeogenic oblique-orthotropic rhizome. An elementary shoot appears during 1 growth period and carries the vegetative and generative parts. The formula of the functional zones of the elementary shoot is determined: the inhibition zone → [innovation zone] → amplification zone → apical bud. It was established that the boundaries of the elementary and annual shoots do not coincide. Elementary shoot includes spring leaf generation (inhibition zone), summer leaf generation with axillary vegetative buds (innovation zone) and vegetative-generative buds (amplification zone). Vegetative-generative shoots appear only after wintering the following spring. They are located below the rosette leaves of the spring generation (this is the beginning of a new elementary shoot). As a result, the annual shoot includes the elementary shoot of the current year, as well as the amplification zone of the elementary shoot of last year.

The work is devoted to the mycelium biochemical composition of Stagonospora cirsii C-211, Calophoma complanata 32.121, Didymella macrostoma 32.52. These phylogenetically distant species of phoma-like micromycetes are the potential mycoherbicides of Cirsium arvense, Heracleum sosnowskyi, and Convolvulus arvensis, respectively. The S. cirsii C-211, C. complanata 32.121, D. macrostoma 32.52 mycelium in the early stationary growth phase was obtained on sucrose-soybean nutrient medium. It was shown that the lipid and carbohydrate (polyols, sugars) profiles of these strains have much in common. We suppose that levels of arabitol and trehalose influence to the stress-resistant of phoma-like micromycetes. In particularly, these carbohydrates serve structural and protective roles in the cell walls during osmotic and temperatures stress. The ratio of phosphatidylcholine to phosphatidylethanolamine and the proportion of phosphatidylserine among structural lipids also determine the properties of mycelium, and can be used to assess its quality.

We defined prospective directions in inclusive teaching Paralympic kind of sport taekwondo WTF LMAI.

The research is focused on studying the possibility of effective use of the dart grip system, the work of the athlete’s hand, to prepare the dartsman for competitions using the MOSAR complex. The experiment uses optical motion capture systems, a set of video cameras, led parameter sensors, and devices that allow to record the movement of body parts and a dart. This method of training and controlling dart throwing can serve as educational and visual material for training future athletes. The use of such motion capture systems in the near future may become one of the main aspects of training, both beginners and professionals, in many sports.

The biological and economic effectiveness of plant protection measures depends not only on the correct choice of pesticide, but also on the quality of its application to the processed target objects. The article discusses the results of assessing the quality of applying herbicides by spraying using low-volume spraying technology, ULV spraying without forced and forced precipitation of small droplets, and treatment with cold aerosol. To assess the impact of the quality of the application of plant protection products on the environmental safety of the use of herbicides, two main indicators were used: – uniform distribution of the working fluid over the treated area: – the amount of drift of small drops from the treatment area. The analysis of methodological approaches and regulatory documents for assessing the potential risk of pesticides for the environment in European countries and in Russia is given.Based on the obtained experimental data on the coefficients of variation in the distribution of the drug over the effective coverage width, an expert assessment of the drug overuse was carried out using various technologies. An expert assessment of the drift of small drops of the working fluid from the treatment zone was also carried out. A comparative assessment of technologies was carried out according to the indicated environmental safety indicators for the use of the herbicide Gezagard WP on potato plantings.

Species composition, quantity participation and spreading of ornamental bushes in current system of Novosibirsk green areas are determined. Upper zone (“Verkhnyaya zona”) of Academgorodok is not taken into research as far as it is a cultural heritage site and a significant site of landscape architecture of the 20th century. Special attention is given to participation of lilac species and cultivars (Syringa vulgaris L., Syringa amurensis Rupr., Syringa josikaea J. Jacq. ex Rchb.). It is pointed out that 62 species of bushes are used in the city, including 3 species of lilac, however their quantity participation is not enough and does not satisfy regulatory limits. Twenty six cultivars from the collection Syringa vulgaris L. of the Central Siberian Botanical Garden SB RAS are recommended additionally. Three cultivars, ‘Nadezhda’, ‘Pamyat’ o S. M. Kirove’ and ‘Olimpiada Kolesnikova’, successfully tested in urban environment are highly recommended. Besides, it is recommended to use wider Syringa amurensis Rupr., and to introduce late-flowering Preston hybrids (Syringa x prestoniae Mc. Kelvey (S. reflexa x S. villosa)), curretly absent in green urban areas, in urban greening in Siberia.

Biogenic amines (BAs) are low molecular weight organic bases with an aliphatic, aromatic, or heterocyclic structure which have been found in many foods. biogenic amines have been related with several outbreaks of food-borne intoxication and are very important in public health concern because of their potential toxic effects. The accumulation of biogenic amines in foods is mainly due to the presence of bacteria able to decarboxylate certain amino acids. Biogenic amines are formed when the alpha carboxvl group breaks away from free amino acid precursors. They are colled after the amino acid they originated from. The main biogenic amines producers in foods are Gram positive bacteria and cheese is among the most commonly implicated foods associated with biogenic amines poisoning. The consumption of foods containing high concentrations of biogenic amines has been associated with health hazards and they are used as a quality indicator that shows the degree of spoilage, use of non-hygienic raw material and poor manufacturing practice. Biogenic amines may also be considered as carcinogens because they are able to react with nitrites to form potentially carcinogenic nitrosamines. Generally, biogenic amines in foods can be controlled by strict use of good hygiene in both raw material and manufacturing environments with corresponding inhibition of spoiling microorganisms. The aim of this review was to give some information about biogenic amines in foods.

The paper presents the results of a comparative study of the cultivated and wild-growing apricot of Dagestan origin according to the morphological characteristics of the fruit and stone at different ripening periods. The pomological evaluation showed that the shape index of the fruit changes by one gradation regardless of the origin of the genotype, while the shape of the stone does not change and remains constant for all genotypes. For example, the fruit of the Kamil cultivar has an ovate shape at an early ripening period, and a circular one at late ripening. During ripening, the weight of the fruit doubles (1.8–2.6 times), while the ratio of stone mass to the weight of the fruit decreases (1.8–2.5 times). For cultivars and wild-growing forms, differences in the change in the linear dimensions and mass of the stone at different maturation periods were noted. The morphological characteristics of the fruit and stone in terms of the coefficient of variation (CV) vary more at the later stages of ripening, and in general are higher in cultivars than in wild plants, and the endocarp varies less than the fruit, at all periods of ripening.

In natural conditions, insertion of Agrobacterium T-DNA into the plant genome and its subsequent transfer via sexual reproduction has been shown for several dozens of species, including species from genera Nicotiana and Vaccinium. In the framework of investigation of possible function of cT-DNA in naturally transgenic species we have shown, that increasing of expression of rolC in Nicotiana tabacum is associated with increase of amount of glucose and total sugar content. Similar trend was observed for rolB/C-like gene in Vaccinium.

A role of the blood circulatory system in a regulation of organism’s physiological functions and in a development of pathological processes is enormous. In this work the specifics of the vascular supply of the northern reindeer’s limbs are presented which are characterized by monotonous scheme. However, the northern reindeer has anatomic specific due to advanced second and the fifth dactyls. In this article there is determination of the development of forelimb’s arterial vessels of the northern reindeer during postnatal ontogenesis. In the postnatal period of development, the most intensive growth in the length and diameter of the great arteries is observed in the first year of the animal’s life, especially in the first month.

Studies have been carried out with the identification of criteria for the anthropogenic stability of agro-gray forest soils according to the main indicators of biological activity under conditions of intensive farming. Soils of this type are dominant in the soil cover of the Republic of Tatarstan, so the results of the experiment can be widely interpolated to similar conditions of soil formation and serve as quickly defined markers for diagnosing anthropogenic pressure. Studies have been carried out in field crop rotation since 1992, using various doses of potassium at three levels of soil nitrogen supply. As a result of long-term use of fertilizers, changes in microbiological activity have been revealed, in the variant with the use of environmentally balanced doses of mineral nutrition, an increase in microorganisms from 3,400 thousand (control) to 4,000 thousand per 1 g of soil is observed. A subsequent increase in the dose of fertilizers led to a decrease in the number of microorganisms relative to the control. Under the influence of the optimal combination of fertilizers (option 3), conditions for the development of actinomycetes, ammonifiers, nitrifiers, cellulose-decomposing bacteria are improved, while very high doses of mineral fertilizers (N180P60K200) worsen them, indicating a decrease in the activity of beneficial bacterial microflora. This leads to a slowdown in decomposition of fiber, nitrification and other biochemical processes. Indicators of the biological activity of the soil correlate among themselves, as well as with other indicators of its fertility, with the productivity of crop rotation and therefore can serve as an additional diagnostic sign when assessing the anthropogenic stability of the agricultural soil of the agricultural soil in intensive agriculture.

A preliminary evaluation towards a breeding value of the Holstein breeding bulls with different genotypes of somatotropin cascade genes is presented: pituitary transcription factor or growth hormone factor (PIT1), prolactin (PRL), somatotropin (GH), somatotropin releasing hormone (GHRH), insulin-like (IGF-1) in the conditions of the Republic of Tatarstan. The research studies the signs (indices) of milk productivity (milk yield and fat in milk) of the closest female ancestors of bulls with different genotypes of somatotropin cascade genes. Studies and analysis have shown that the bulls with the mixed genotypes ABAALLBBAA (10269 kg), AAAALLBBAB (4.13 %) and BBAALLABBB (9402 kg and 4.06 %) had the highest and optimum evaluation by origin, judging by the bulls’ pedigree (geneological) index. The frequency to meet bulls with the desired mixed genotypes was low and amounted to 4.28–5.71 %.

The necessity of reformatting the structural organization of processes, which determines the priority of using the ways, forms and methods of the sixth technological structure, in particular, biotechnologies is actualized. The main definitions are given: nursery, biologization, greening, resource saving, promising technology. The analysis of the efficiency of sapling fruit production, the structural organization of specific processes for the production of planting material and sapling is presented. The main elements of the agrocenosis, which are most susceptible to chemical and technogenic effects, have been determined. The analysis of soil fertility and the state of soil biota is carried out, the problem of microbiological processes branch in all agrocenosis elements is actualized. It was found that the increased chemical load on the agrocenosis of the fruit nursery led to the destruction of microflora useful species. The nature of plant organs infection has changed, and negative changes have occurred in the plants immune status. The priority role of biologization in ensuring the stability of the fruit nursery agrocenosis has been substantiated.

The investigations are made of cherry biological peculiarities and disease excitants composition. The domination of necrotrophic fungi and Pseudomonas syringae van Hall bacteria in pathocenosis is shown. The fact of microbiota associative lesion of plants is established. The antagonist action of isolated bacterium in relation to Cytospora leucostoma (Pers.) Sacc., Alternaria alternata Keissl., Fusarium oxysporum Schlecht., Monillia cinerea Bonord is detected. The character of isolated bacterium metabolites, pathogenic fungi and their association effect on a host-plant is established. The ability of bacterium to lower the activity of phytotoxins secretion in fungi when cultivated together is identified. It has been found that it is the fungal pathogens causing the development of die-back in cherry in investigated gardens, whereas P. syringae bacterium, when in latent state, plays a part of protector and permits to suppress the development of fungal infection. Taking into account the fact that this bacterium is pathogenic, the works of advanced breeding for resistance of the horticultural crops to bacterial blight are recommended.
