Evaluation of the influence of heat treatment modes of steel 60С2A on its mechanical characteristics and increasing the performance of the generator of hydrodynamic oscillations

The article considers a variant of the drilling head, in which a generator of hydrodynamic oscillations is placed. The main task of research is to select the mode of heat treatment of the resonator material, which ensures an increase in its plasticity. Due to this, an increase in the service life of the resonator is expected as a result of a decrease in sensitivity to stress concentration in the region of defects, including cracks. The main part of the research is related to the determination of the 60С2A steel mechanical characteristics, both in the state of delivery and after heat treatment. With the help of metallographic analysis, the author showed that the proposed options for heat treatment don’t lead to deviations in indicators from the requirements of regulatory documentation. It was determined that the highest value of the plasticity index is realized during heat treatment, which includes annealing + hardening + tempering. A variant of heat treatment of steel 60C2A is proposed, which provides an increase in the service life of the drilling head. Keywords: heat treatment, steel 60С2A, metallographic analysis, tensile test, mechanical characteristics, plasticity index

Assessment of the influence of pesticides based on glyphosate on the health of agricultural producers

Introduction. The results of a hygienic risk assessment of the use of pesticides based on glyphosate in agricultural production are presented. The study of the pathogenetic mechanisms of action on the body of widely used glyphosate-containing herbicides and the search for markers of health conditions that change under the influence of these drugs are of increasing interest for the early diagnosis of pathological processes and the prevention of occupational and occupational diseases. The aim of this study was to assess the health effects of glyphosate-based pesticides on the health of operators in an agricultural environment. Materials and methods. The clinical material for the study was the plasma and erythrocytes of the peripheral blood of operators in contact with glyphosate-containing pesticides. As a control group, 20 clinically healthy individuals of the same age group, who had no contact with the studied pesticides, were selected. There were assessed leading indices of general clinical and biochemical blood tests and markers of endogenous intoxication and oxidative stress. Results. There were established acceptable risk of exposure to pesticides on workers, subject to compliance with technological regulations and safety requirements. Minor deviations of indicators of general and biochemical blood tests were revealed. A statistically significant increase in the total level of carbonyl derivatives compared to control was obtained among operators who had more substantial contact with glyphosate-containing pesticides. Conclusion. Working conditions when using preparations in the form of aqueous solutions containing glyphosate, using ground-based spraying of steam fields with a consumption rate of 8 l / ha, subject to compliance with regulations and safety measures, comply with hygienic requirements. The established statistically significant changes in the blood parameters of the operators in comparison with the control group indicate the presence of a risk to the health for workers in contact with glyphosate-containing pesticides and indicates the need for additional biochemical studies during periodic medical examinations of agricultural workers for the early detection of deviations in the health state caused by exposure to pesticides, including those containing glyphosate.

Biomechanical Study of Walking and Vertical Posture in 4-6-year-old Children with Spastic Forms of Cerebral Palsy

Rehabilitation of children with cerebral palsy (CP) requires a systematic approach and dynamic assessment of the results achieved. The development of methods for assessing the dynamics of motor disorders during medical rehabilitation is of great importance for modern medical rehabilitation. In recent years, there are more and more scientific papers devoted to the study of biomechanical disorders of locomotion in patients with CP. Aim. To assess the features of walking biomechanical characteristics and vertical pose stability in of children 4-6 years old with spastic forms of CP for further formation of rehabilitation groups, taking into account the identified functional disorders. Material and methods. The study included 20 patients (5.4±0.67 years) with spastic forms of CP. A comparative analysis of walking parameters and stabilography of children with spastic diplegia and hepiplegic CP among themselves and with a group of conditionally healthy children (norm group) (n=12) was performed. Results. A statistically significant decrease in the following indicators was found in children with hemi-and paraparesis: walking speed, double step length, and hip flexion/extension angle. Deviations of indicators are more pronounced in spastic diplegia, but are not always equivalent for both limbs; there is a violation step cycle proportions. the decrease in the length of the double step is more pronounced on the affected limb; there is a decrease in the angle of flexion/extension in the knee joint, more pronounced on a healthy limb in patients with hemiplegic CP. A wide range of stabilographic indicators values is observed in both study groups. However, only the average position of the pressure center relative to the frontal plane statistically significantly differs from the norm in the group of children with hemiparesis. In paraparesis, such differences from the norm are much more common: the area of the statokinesiogram, the maximum amplitude of fluctuations in the center of pressure and the energy of the frequency spectrum. The range of values for most indicators in paraparesis is wider. Conclusion. The revealed biomechanical features of walking and stability of the vertical posture of children with spastic forms of CP can serve as a basis for the development of rehabilitation programs. Clinical and rehabilitation groups of children with CP should be formed taking into account the severity of static-dynamic disorders present in patients. This approach will make it possible to plan further rehabilitation treatment of such patients and adequately assess the results obtained.

Research long-term fluctuations in winter temperatures. Methods for analyzing the intensities and synchronicities of fluctuations in fuel consumption

The article deals with the problem of assessing the deviations of the meteorological characteristics of the heating season. The usual method of calculating the relative deviations of indicators from the arithmetic mean is not suitable. A requirement is imposed on the “new” averages and estimates of deviations of meteorological characteristics, which follows from their properties: the duration multiplied by the average daily temperature difference for the heating period should be equal to the integral temperature difference. The application of this property to the means and to the very estimates of the deviations of meteorological characteristics makes it difficult to determine the latter. A method is being developed to determine the intensities of fluctuations in the meteorological characteristics of the heating season. Intensities show how much, on average, the duration, average daily and integral temperature differences for the heating period can deviate from the average expected level. A technique is being developed for reflecting synchronous and asynchronous fluctuations in deviations of meteorological characteristics, and the contributions of these fluctuations are determined.

Comparative analysis of the composition of intestinal microbiome in patients with liver diseases

Aim: to analyze the composition of the intestinal microbiome in patients with liver diseases of various etiologies.Materials and methods: 128 patients of different sexes with pathological liver lesions were examined. The diagnosis of diseases was carried out using laboratory and instrumental methods of research. The study of the composition of microbiota in qualitative and quantitative indicators was carried out using standard bacteriological methods. The statistical analysis was performed using Student's t-test. Differences in indicators were considered significant at P<0.05.Results: the comparative analysis of the composition of the intestinal microbiocenosis of patients with various liver diseases showed significant drops in the titers of symbiotic bacteria: lactobacilli to 100–104 CFU/ml, bifidobacteria to 105–108 CFU/ml, enterococci to 105–106 CFU/ml and typical E. coli to 103–106 CFU/ml, as well as an increase in the number of opportunistic microorganisms: Candida to 104–109 CFU/ml, hemolytic E. coli to 107–109 CFU/ml, Staphylococcus spp. to 104–106 CFU/ml, Klebsiella spp. and Enterobacter spp. to 106–108 CFU/ml. According to the degree of colonization of associative and conditionally pathogenic microbiota of the intestinal tract, significant fluctuations in the deviations of indicators were recorded in women and men with non-alcoholic steatohepatitis, alcoholic hepatitis and hepatitis C.Conclusions: the study revealed the significant imbalance of microbiome of the gastrointestinal tract: there was a tendency to increase the quantitative and qualitative indicators of the content of representatives of the opportunistic microbiota against the background of decreasing titers of symbiotic microorganisms. The most significant deviations in the composition of the intestinal microbiome were observed in patients with hepatitis C. The differences in the microbial landscape of the intestine of patients of different sex with liver diseases are shown, which was mentioned in the changing relationship of individual members of the intestinal microbiota

THE MODEL OF THE EXTERNAL ENVIRONMENT OF THE REGIONAL SOCIO-ECONOMIC SYSTEM

The article reveals the concept of National projects of the Russian Federation as a determining influence within the framework of the developed control system of the regional socio-economic system. A methodology has been developed that provides the definition of indicators of National projects of the Russian Federation in classification terms of components for the regional socio-economic system and the functional control device. It is proposed to understand the external environment of influence on the regional socio-economic system as its environment, which is determined by the complex and versatile influence of political, economic, demographic, technological and other disturbances. The external environment was considered in the work as a “disturbing” element, the influence of which must be taken into account when describing the object of control -the regional socio-economic system. A classifier of environmental factors affecting the regional socio-economic system was formed, which was distinguished by combining regional, country and global interpretations of environmental factors affecting the regional socio-economic system. A method for analyzing dynamic information flows in the control system of the regional socio-economic system was developed. The concept of environmental disturbances was introduced, their linguistic variable was set, and the order of estimating their displacement was determined. The concept of interference (noise) measurements is introduced, which determine the deviation of indicators of information (signals) coming from the external environment of influence on the measuring devices of the regional socio-economic system control system. A linguistic variable describing the interference (noise) of measurements is set. Thus, the presented materials will allow us to proceed in the future to the formation of a comprehensive methodology for managing the regional socio-economic system based on the analysis of the external environment.

Оцінка впливу лакування на кольоровідтворення рекламної аркушевої продукції

The results of the study revealed a deviation of indicators of the color differences as well as a slight difference in the degree of gloss for the prints covered with water-dispersion and UV-varnish. The mentioned above provides the necessity of adjusting the processes of printing and varnishing to achive the standards of the studied parameters. This is possible to obtain trough reducing the volume of ink feeding and adjusting the feeding force of the varnishing jet and the process of its spreading and fixing speed. The most qualitative varnishing the prints can be provided applying the offset printing and processing ‘in line’ with a lacquer section, equipped with the chambered doctor blade system with an anilox roller. Taking into account the tendencies of the development of the publishing and polygraphic complex, reducing the cost and the time of execution of the order, as well as assessing the economic and technological parameters of possible ways of decoration of advertising products such as cheapness, simplicity, efficiency, prevalence, it can be argued that the preferences should be given to the application of varnish on the print. In order to produce competitive products, it is necessary to meet the relevant quality requirements that had been currently extending. The quality control of the prints, decorated with two different types of varnish, will allow to analyze the factors influencing on the color reproduction, the degree of gloss, to assess the cost-effectiveness of applying one or another type of varnish depending on the obtained results and technical and economic indicators and taking into account the difference in the cost of consumable material as well. Understanding the current state of varnishing, the prospects of the development of ink and varnish materials and analysis of the technological process of varnishing is an important aspect for improving this process.

Benchmarking of bank performance using the life cycle concept and the DEA approach

Despite the widespread use of benchmarking as an effective tool for improving the efficiency of the bank’s functioning, its implementation does not take into account the relation between comparable performance indicators, the choice of benchmark for comparison, deviations of indicators from target values with stages of the bank’s life cycle, which cause differences in the intensity and characteristics of development of financial institutions. The procedure for identifying a reference bank for comparison is also insufficiently specified, which is important in terms of adapting its experience by the recipient bank due to the possible fundamental differences in their functioning. Therefore, the article has modified the technology of benchmarking of the bank’s performance based on the life cycle concept and the DEA approach. The research is based on the use of the DEA method to determine the most efficient bank as a reference bank in benchmarking comparison; canonical analysis – for the formation of a list of indicators of bank performance; cluster analysis – to substantiate the levels of deviations of the actual values of comparable indicators from the target ones. The study envisages, firstly, the selection of indicators for benchmarking comparisons based on the identification of causal relationships between the indicators of subsystems “Finance”, “Customers”, “Business processes”, “Personnel development” that arise at each stage of a bank’s life cycle; secondly, the choice of a benchmark bank for comparison according to the maximum value of the performance indicator calculated through the DEA method for a set of banks that are at one and the same stage of their life cycle; thirdly, definition of the range of deviations (low, permissible, critical) of the actual values of comparable indicators of the effectiveness of management of finance, customer base, business processes and personnel of the bank from the target ones. A practical testing of the benchmarking technology was carried out on the example of Ukrainian banks, whose stage in 2016 was identified as “intense growth”.

Показатели иммунной системы у подростков с остеоартрозом на фоне гипермобильного синдрома

Indicators of an immunological homeostasis in 84 adolescents aged 12-18 years with osteoarthrosis (OA) against the background of hyper mobility of joints (GMS) are studied. The group of comparison was made by adolescents of identical age with osteoarthrosis without hyper mobility of joints. The considerable changes in the immune system which were characterized by disturbances in various links of immunity and manifested themselves by the depression of monocyte- phagocytic system of the T-link, the moderate activation of the V-link, dysglobulinemia, and compliment increase were established. More considerable deviations of indicators were observed in patients with osteoarthrosis and simultaneous hyper mobility of joints and accrued with the extent of increase in hyper mobility of joints. Increase in immunological frustration in patients with growth of joint mobility degree was defined.

If I Leave Here Tomorrow: An Option View of Migration When Labor Market Quality Declines

In this paper we provide a framework for determining when it is optimal to move when labor market opportunities are declining. We model the decision to migrate as akin to owning a financial option in which the exercise price is the fixed cost of moving. We show that a higher fixed cost associated with moving and a higher standard deviation of the quality of the labor market reduce the incentive to migrate. We then empirically examine whether the standard deviation of indicators of labor market quality reduce the likelihood of migration. Our findings strongly support this hypothesis, and imply that for the relatively mobile population of high-skilled workers, the counterfactual outmigration rates that would obtain if future labor-market quality were known with certainty are more than twice observed rates.
