Published: June 2021

The article deals with the theory and practice of the influence of fitness on the health promotion of students. The authors of the article conducted an experiment and found the effectiveness of fitness classes in the sports club to improve the health of students. As a result of the experiment, it was concluded that students are able to work better in their physical activity, interest in physical education, development of musicality, plasticity. Many students experienced normalization of body weight and formation of correct body posture. After the experiment, views on the physical perfection and level of preparation of students have changed significantly, through fitness classes, and make new demands on the content of fitness classes. This approach to the issue of physical education of students increases the importance of strength training (functional development of the muscular system, the formation of the figure and appearance) with consistently increased attention to the quality of aerobic fitness and performance. These two factors, namely new views on the problem of physical fitness and a limited period of training are key in planning and developing the content of new health techniques. Improved physical development of students was facilitated by dosed physical exercises in the form of moderate physical activity, with the help of fitness programs, as well as additional physical activities in extracurricular activities, which ultimately made it possible to effectively maintain the physical condition and health of students.
The motive for activating fitness classes for students should be the positive impact of classes and improving physical fitness.

Published: June 2021

Given the widespread use in medicine of opioid analgesics, today it is extremely important to study the morphofunctional changes of various organs with prolonged exposure to opioids. In the modern scientific literature there are works in which changes of biochemical indicators of blood at use of narcotic analgesics in experiment are covered. To study the changes in the biochemical parameters of blood and urine with long-term use of Nalbuphine is an important area of research. The aim of the study was to detect changes in some biochemical parameters of blood and urine of rats at six-week administration of therapeutic doses of Nalbuphine. The study was based on 40 white adult male rats weighing 180-260 g, which were injected daily for six weeks with Nalbuphine injection 20 mg daily, intramuscularly in therapeutic doses. Daily diuresis and creatinine content were determined in urine samples. The content of total protein, creatinine, urea, calcium and phosphorus was determined in blood samples. The glomerular filtration rate was also determined by the clearance of endogenous creatinine. All statistical calculations were performed using R Studio v.1.1.442 and R Commander v.2.4-4 software. The results of the study showed that six weeks of therapeutic doses of Nalbuphine affects the filtration and reabsorption function of the kidney. The use of Nalbuphine for two weeks does not cause significant changes in biochemical parameters, but the established deviations may indicate the first signs of renal dysfunction. Further use of Nalbuphine, including the end of the sixth week of the experiment, leads to significant changes in the filtration and reabsorption functions of the kidneys, as evidenced by statistically significant changes in the biochemical parameters of blood and urine of rats. The data of the study can be used to compare with changes in the functional state of the kidneys caused by prolonged use of Nalbuphine, its withdrawal and the use of other drugs in combination with Nalbuphine. It is also advisable to compare the results of the study with the morphological changes of the kidneys at different times of use of Nalbuphine.

Overweight and obesity play a negative role in gynecological and obstetric practicE.In women, the frequency of infectious pathology increases against the background of metabolic disorderS.The most common form of infectious vaginitis is bacterial urogenital candidiasis, in the etiological structure of which a significant role belongs to the fungi Candida albicans, as well as Candida non-albicans: C.glabrata, C.tropicalis, C.parapsilosis, C.krusei. Associations of Candida fungi with various representatives of opportunistic microflora, such as gram-positive and gram-negative aerobic, facultative-anaerobic and obligate-anaerobic microorganisms, are often formed. As a result, numerous bacterial pathogens multiply and the number of lactobacilli, which are usually part of the bacterial flora of the vagina, is significantly reduced. In bacterial vaginosis (BV), the concentration of anaerobic pathogens Peptostreptococcus sp, Gardnerella vaginalis, Peptostreptococcus Mobiluncus sp, Mycoplasma hominis can increase 100 timeS.Activation of Atopobium vaginae and Gardnerella vaginalis, which play a “key” role in the pathogenesis of BV, has been proven. The aim of the study was to study changes in the vaginal microbiome in women with candidiasis and bacterial vaginosis in order to improve existing treatment regimenS.We examined 120 women of reproductive age with overweight and obesity. The degree of microbial contamination was determined and the maximum possible spectrum of aerobic and facultative-anaerobic microflora was detected. In women with vulvovaginal candidiasis, overweight and obesity, a high concentration (lg5.8 CFU/ml) of Candida fungi was found, and in 95% of patients two-, three- and four-component associations of Candida fungi with various representatives of conditional pathogenic microflora. Lactobacillus deficiency was found in 58.3% of patients, and their complete absence – in 10.0%. Bacteriological examination of the vaginal contents of women with vaginosis and obesity revealed significant dysbiotic disorders of the vaginal microflora, three-, four- and even five-component associations of anaerobic and facultative anaerobic microflora with a predominance of anaerobeS.A low seeding level of lactobacilli (lg2.2 CFU/ml) was established. Thus, the gram-positive anaerobic and facultative anaerobic microflora of Firmicutes have a significant share in the spectrum of vaginal microflora in overweight and obese patients, in contrast to non-obese women of reproductive agE.In women of reproductive age with vulvovaginal candidiasis and obesity, in contrast to non-obese patients, a higher frequency of fungal-bacterial associations, a higher quantitative level of vaginal contamination by Candida albicans and non-albicans with a lack or general absence of lactoflora.

Published: June 2021

The paper presents results of the modelling of heat transfer at film boiling of a liquid in a porous medium on a vertical heated wall. Such processes are observed at cooling of high-temperature surfaces of heat pipes, microstructural radiators etc. Heating conditions at the wall were the constant wall temperature or heat flux.
An analytical solution was obtained for the problem of fluid flow and heat transfer using the porous medium model in the Darcy-Brinkman. It was shown that heat transfer at film boiling in a porous medium was less intensive than in the absence of a porous medium (free fluid flow) and further decreased with the decreasing permeability of the porous medium. A sharp decrease in heat transfer was observed for the Darcy numbers lower than five. The analytical predictions of heat transfer coefficients qualitatively agreed with the data [14] though demonstrated lower values of heat transfer coefficients for the conditions of the constant wall temperature and constant wall heat flux.

The problem of drop deformation and breakup in shear flow represents academic and practical interest and has attracted close attention over the intervening decades. Drop breakup is important for a wide range of engineering and biomedical applications including production and processing of emulsions, aerosols, etc. Although drop breakup operations are widely used in various industries, however, till quite presently there is no unequivocal treatment of the physical mechanism, which causes the fragmentation of dispersions in shear flows. In this paper the principles of constructing a mathematical model, which predicts the evolution of initially spherical droplet in shear flows of viscous liquid over a wide range of flow regimes as well physical parameters of both liquid phases, are considered. A mathematical model is presented that describes the deformation of a single drop suspended in another immiscible liquid under the combined action of three forces, namely, hydrodynamic force, capillary force and dissipative viscous force. The influence of each of these forces on the process of droplet deformation is discussed in the paper.
The focus of the study is to more deeply analyze the dynamics of droplet deformation in shear flows and the transitional effects associated with current droplet shapes. Particular attention is paid to the analysis of critical conditions for the onset of irreversible deformation of droplets, which leads to their destruction. The deformed droplet is assumed to be in the form of prolate ellipsoid of revolution. The drop deformation is regarded as motion of the centers mass of the half-drops, symmetrical with respect to the drop center.
The results of numerical calculations for droplet deformation in shear flows in comparison with experimental data of other authors are presented. A simple criterion for destruction of droplets in shear flows has been obtained. The results of the analysis confirm the reliability of the model and the competency of the assumption made. The model is able to predict the nature of droplet deformation and the conditions for their destruction in shear flows with known operating parameters with a greater degree of accuracy than the existing empirical relationships.

Published: June 2021

The results of the study of heat transfer under forced convection in a flat porous microchannel taking into account the boundary conditions of slippage of the first and second order are considered.
The simulation showed that with decreasing porosity the flow velocity in the central part of the microchannel and the slipping velocity on the wall decrease due to the increase in hydrodynamic resistance. Taking into account the influence of the boundary conditions of the second order shows that the magnitude of the velocity jump on the wall varies depending on the value of the parameter A2. The jump decreases with a positive value of A2, with a negative value - increases in comparison with the case A2 = 0 (first order boundary conditions).
Qualitatively similar effects of porosity and second-order boundary conditions were also observed with respect to temperature profiles.
The results of the calculation of the relative Nusselt number showed that the decrease in porosity contributes to the intensification of heat transfer.
The dynamics of the change in the heat transfer coefficient with an increase in the Knudsen number indicates that an increase in the Prandtl number also leads to an improvement in the thermal interaction of the flow with the channel wall. The analysis of taking into account the boundary conditions of the second order showed that at small values of the Prandtl number (Pr ≤ 1) the influence of the parameter A2 was not observed. At A2 < 0 the effects of the boundary conditions of the second order lead to an increase in the relative Nusselt number, whereas at A2> 0 the value of the normalized Nusselt number decreases in comparison with the case A2 = 0 (boundary conditions of the first order).

Published: June 2021

Within the framework of the work, experimental and laboratory studies of a complex of heat and mass transfer processes in multicomponent disperse systems that exhibit emergent properties have been carried out.
The aim of the work is to determine the key factors that affect the properties of the final product, and bifurcation points for complex dispersed systems in terms of the mechanisms of structure formation.
The authors determined the influence of key parameters such as the process temperature and shear stresses that arise in systems during processing in rotary-pulsating devices of the disk-cylindrical type.
For systems with polyelectrolyte structures, the temperature ranges have been determined at which the intensity of the solvation process is maximum.
The investigated multicomponent systems are sensitive to shear stress and the duration of its exposure. The limiting shear stresses are determined at which the destruction of structures begins and the system becomes fluid.
Based on the results of the complex of works, a schematic diagram and a pilot plant for obtaining poly-component structured systems were proposed. Вatches of bactericidal sanitary-hygienic means and application medical-prophylactic means were obtained at the proposed installation and transferred for testing.

Indigenous elderly is one of the most medically underserved groups and are often left out, which resulted in significant health disparities. Besides, research on the indigenous elderly health and wellbeing is somewhat limited despite the world slogan of health equity for social sustainability. Hence, having to assess the health status of the group will make a balanced effort for improving their overall quality of life. This paper aims to evaluate and synthesise the indigenous elderly health and wellbeing by using the systematic review of Scopus-indexed publications, published from 2003 to November 2020. Ninety-three articles served as the initial data, but only 22 articles were eligible to be used for the analyses of 1) perception and beliefs on health behaviour, 2) physical and mental health practices, 3) impactful studies and 4) implications of the studies towards policy and healthcare delivery. The findings revealed developed countries like the USA, Canada, and New Zealand have placed greater efforts in voicing out the group needs. Suggestions for future research are to focus on intervention programs and improvement of the healthcare policy development for the indigenous elderly ease of access to healthcare, fundamental for reducing the social gaps.

Published: June 2021

There has been a significant falling rate in Malaysians’ English proficiency in recent years. This paper studies a proficient English L2 user aiming to investigate the case’s engagement in learning English from birth to primary 6. It is hoped to find out the implications (possible procedures and strategies) for moulding a child into a competent English user in the non-English setting in Malaysia. “Reflexivity”, a qualitative research method, was employed. The sample’s parent reflected and detailed the child’s learning journey with evidence of learning and achievements. Apart from the thorough recount on the child’s engagement with the L2 before formal education, the sample’s writings done in primary school were randomly selected and scrutinized with a text-analysing digital tool “Text Inspector©” whose analysis results were mapped with CEFR levels to examine his progression towards the mastery of the target language. The findings demonstrate that, first, exposing a child to English right after birth greatly triggers the learning process and the effects are significant; second, the provision of rich family literacy greatly complements the lacking of English environment; third, “imitation” can be an essential strategy to expedite the learner’s command of English.

Published: June 2021

This study aims to examine the relationships between the internal environment (IERH), basic requirement policy (PRRH), and the performance of retirement homes (PRH). 205 out of 400 questionnaires returned and used for the study. The three variables under study were IERH (8 items), the PRRH (6 items), and PRH (8 items). Reliability analysis was run and all three variables showed high Cronbach Alpha values ranging from 0.83 to 0.87 thus indicating high reliability. The findings of the Pearson Correlation analysis suggested that the relationship between IERH and PRH is r=0.80**; p=0.00, while the relationship between the PRRH and PRH is r=0.63**; p=0.00. The findings suggested that there was a positive and significant relationship between PRH with IERH and PRRH. IERH had a strong positive relationship with the PRH. In terms of the relationship between IERH and PRRH, there was a positive and a moderate relationship (r=0.54**; p=0.00). Hence, in order to promote good performance, a RH must ensure that the IERH either meets or exceeds the expectations of the tenants and fulfils the basic requirements of PRRH.

This is very related to workers who is repeat the same tasks and depending on manual handling processes. Posture analysis evaluations using the Rapid Upper Limb Assessment (RULA) and Rapid Entire Body Assessment (REBA) tools have been used to analyse the working postures of workers at poultry feed manufacturing industry. The aim of this study was to identify workersâ€™ risks of working posture problems, and to propose a standard of procedure to reduce MSDs and CTDs. The assessment was conducted using RULA and REBA worksheets. Three selected workers are divided into three different tasks. From the analysis had been done, the score obtain for RULA method is 7, 6 and 7 for Workers 1, Workers 2 and Workers 3 respectively. Meanwhile for REBA method, the score is 12, 6 and 5 for workers respectively. It is shows that the working postures is in high-risk, which need to be considered. It is expected that this research will help by proposing proper SOP and work position for reducing the risk of WMSDs in industry. In addition, this research is expected to increase the awareness regarding on the good working postures among workers.
