Authors: Davybida N. , Sobchuk V. 
Published: July 2023

At present, the scientific and methodical literature has accumulated a lot of data on the positive effect of corrective exercises in scoliosis, the latest, modern methods of their implementation have been developed and implemented in the practice of treatment, a large number of aids have been invented in the form of exercise machines, Yevminov’s board, sports accessories and equipment, various types of massage, but the problem remains not fully studied and needs research.
Today, there are many new technologies and methods in the world, which are aimed at additional diagnosis, prevention and treatment of scoliosis. For the purpose of diagnosis, the methods of Chaplin, Ferguson, Kob, Lekumu, O. Sminko are widely used in clinical practice, and scoliosis can also be diagnosed using a scoliometer, X-ray diagnostics, computer tomography, and magnetic resonance therapy. Parents, teachers themselves can diagnose/see visually the curvature of the spine in a child by some signs, but subjective methods of assessing scoliosis do not provide quantitative characteristics of posture, instead, objective methods provide detailed objective information about the condition of the spine and changes in the shape and orientation of the body in space and consult a doctor for a more detailed diagnosis. The issue of specifics of massage techniques and techniques for scoliosis of various degrees of development, as well as its place in the complex of rehabilitation measures, has not been practically resolved, which is a significant drawback. Therefore, the issue of prevention and correction of posture disorders is one of the important problems of physical education of students and an urgent problem of modern times.
Analysis of scientific and methodical literature; observation is carried out for the correct selection of control and experimental groups; testing motor abilities using special tests, each of which allows to assess the level of physical activity, and comparison before and after the experiment; the experiment involves the creation of new methods of rehabilitation; method of mathematical processing of results.

Discussions about the need for the development of youth and mass football in Ukraine for a long time have remained only conversational creativity. Attempts to do half-measures do not bring any positive results. At the same time, the long-term experience of other developed countries in the field of football shows that even full-fledged measures do not always immediately give the desired result. Only an exceptionally thought-out systematic approach over a long period of time is capable of ensuring the development and effectiveness of a multidisciplinary concept, methodology or program.
The experience of such developed countries in terms of football as Germany has proven, and the football managers of England, Belgium, Spain, Netherlands, France and many other leading football countries agree with them, that the bet on youth is a win-win, and in this case, universal profit is guaranteed can be considerable.
In the long term, the Ukrainian Football Association could consider studying the German experience, both at the club and national level. For Ukrainian football clubs, the traditional management system with the rule "50% shares + 1 share" seems very appropriate. Such a model would not only develop the concept of developing young football talents, but also contribute to the de- oligarchization of Ukrainian football.

Published: July 2023

Introduction: Pulmonary carcinoma is the most prevalent cancer in the world, followed by breast cancer. It has high mortality rates in men and women mainly due to its ability to metastasize. Metastases from lung carcinoma to the breast are extremely rare. The first case described occurred in 1965 and since then there are few cases of this condition reported in the world medical literature. Case report: A 59-year-old woman who complained of low back pain in May 2017. The investigation revealed a metastatic site in the fifth vertebra of the lumbar spine with unknown origin. Six months later, a new lesion was found in the ninth vertebra of the thoracic spine. Immunohistochemistry showed positivity for cytokeratin 7 and TTF1 markers, confirming the hypothesis of lung carcinoma as the primary site. In March 2018, the patient evolved with a symptomatic nodule in the right breast on ultrasound and with positivity for TTF1 on immunohistochemical study, confirming the metastasis of lung carcinoma to the breast. Treated for two years until March 2020, when she presented multiple brain metastases. Patient had no therapeutic success and died. Conclusion: The difficulty in diagnosing lung carcinoma metastasis to the breast stands out, surgeons, clinicians and pathologists should consider this diagnosis, although rare.

Long-Range Surface-Directed Polymerization-Induced Phase Separation: A Computational Study
Authors: Ghaﬀari Shima , Chan Philip K. , Mehrvar Mehrab 
Published: July 2023

<p>The presence of a surface preferably attracting one component of a polymer mixture by the long-range van der Waals surface potential while the mixture undergoes phase separation by spinodal decomposition is called long-range surface-directed spinodal decomposition (SDSD). The morphology achieved under SDSD is an enrichment layer(s) close to the wall surface and a droplet-type structure in the bulk. In the current study of the long-range surface-directed polymerization-induced phase separation, the surface-directed spinodal decomposition of a monomer-solvent mixture undergoing self-condensation polymerization was theoretically simulated. The nonlinear Cahn-Hilliard and Flory-Huggins free energy theories were applied to investigate the phase separation phenomenon. The long-range surface potential led to the formation of a wetting layer on the surface. The thickness of the wetting layer was found proportional to time t*(1/5) and surface potential parameter h(1)(1/5). A larger diffusion coefficient led to the formation of smaller droplets in the bulk and a thinner depletion layer, while it did not affect the thickness of the enrichment layer close to the wall. A temperature gradient imposed in the same direction of long-range surface potential led to the formation of a stripe morphology near the wall, while imposing it in the opposite direction of surface potential led to the formation of large particles at the high-temperature side, the opposite side of the interacting wall. </p>
Degradation of aqueous methyl tert-butyl ether by photochemical, biological, and their combined processes
Authors: Asadi Azadeh , Mehrvar Mehrab 
Published: July 2023

<p>The degradation of aqueous methyl tert-butyl ether ( MTBE) at relatively high concentrations was investigated by various photoinduced oxidation processes such as UV/H2O2 and UV/TiO2 as well as biological processes and their combination. It was shown that the degradation of MTBE by UV/H2O2 and TiO2 photocatalytic followed a first-order model with apparent rate constant of 1.31 x 10(-1) and 1.21 x 10(-2) min(-1), respectively. It was observed that UV/H2O2/ TiO2 process did not have any advantages over each of the other processes alone. The biodegradation of methyl tert-butyl ether ( MTBE) was evaluated using aerobic mixed culture with three different approaches, including ultimate biological oxygen demand (BODU) assessment, nonacclimated, and acclimated mixed cultures. The apparent rate constant for the biodegradation of MTBE by nonacclimated mixed culture was 4.36 x 10(-2) day(-1). It was shown that the acclimatization of the mixed cultures enhanced the rate of biodegradation of MTBE to 3.24 x 10(-1) mg L-1 h(-1). Finally, the effects of the photocatalytic pretreatment of aqueous MTBE on its subsequent biological treatment were studied. It was observed that the rate of bioreaction was not enhanced and the photocatalytic pretreatment had adverse effects on its biological treatment so that the apparent rate constant decreased to 2.83 x 10(-1) mg L-1 h(-1). </p>

Authors: Mehrvar Mehrab , Anderson William A. , Moo-Young Murray 
Published: July 2023

<p>Photocatalytic degradation of tetrahydrofuran, 1,4-dioxane, and their mixture in a slurry photoreactor was studied. Using both GC/MS and ion chromatography (IC) methods, possible intermediates were detected and the reaction mechanism pathways for both compounds were proposed. Kinetic models were developed and the kinetic parameters were estimated using a statistical method of non-linear parameter estimation in which all experimental data were utilized. It was shown that tetrahydrofuran was disappeared via direct oxidation as well as hydroxyl radical attack. A modified Langmuir-Hinshelwood described the degradation behavior of tetrahydrofuran and the binary system. 1,4-Dioxane obeyed a simple Langmuir-Hinshelwood kinetic form in the single compound system. </p>
Computer Simulation of Anisotropic Polymeric Materials Using Polymerization-Induced Phase Separation under Combined Temperature and Concentration Gradients
Authors: Ghaﬀari Shima , Chan Philip K. , Mehrvar Mehrab 
Published: July 2023

<p>In this study, the self-condensation polymerization of a tri-functional monomer in a monomer-solvent mixture and the phase separation of the system were simultaneously modeled and simulated. Nonlinear Cahn-Hilliard and Flory-Huggins free energy theories incorporated with the kinetics of the polymerization reaction were utilized to develop the model. Linear temperature and concentration gradients singly and in combination were applied to the system. Eight cases which faced different ranges of initial concentration and/or temperature gradients in different directions, were studied. Various anisotropic structural morphologies were achieved. The numerical results were in good agreement with published data. The size analysis and structural characterization of the phase-separated system were also carried out using digital imaging software. The results showed that the phase separation occurred earlier in the section with a higher initial concentration and/or temperature, and, at a given time, the average equivalent diameter of the droplets was larger in this region. While smaller droplets formed later in the lower concentration/temperature regions, at the higher concentration/temperature side, the droplets went through phase separation longer, allowing them to reach the late stage of the phase separation where particles coarsened. In the intermediate stage of phase separation, was found proportional to t*(alpha), where alpha was in the range between 1/3 and 1/2 for the cases studied and was consistent with published results. </p>
Photocatalytic degradation of aqueous organic solvents in the presence of hydroxyl radical scavengers
Authors: Mehrvar Mehrab , Anderson William A. , Moo-Young Murray 
Published: July 2023

<p>Tetrahydrofuran (THF) and 1,4-dioxane (DIOX) are two common solvents that are found in contaminated groundwater. Photocatalytic degradation of these two organic solvents in water was studied in the presence of carbonate and bicarbonate, which are hydroxyl radical scavengers. The reactions were performed in an annular slurry photoreactor. It was found that bicarbonate and carbonate ions acted as hydroxyl radical scavengers and slowed down the DIOX degradation rate but did not significantly affect the THF degradation rate. The slight enhancement in the THF degradation rate in the presence of sodium bicarbonate may be due to the increase in pH. In addition, it appears that bicarbonate and carbonate ions were reduced to other organic species during the photocatalytic reaction. </p>

Published: July 2023

<p>Two different commercial photocatalysts, Degussa P25 and Hombikat UV 100, were used to degrade 1,4-dioxane photocatalytically in an annular slurry photoreactor. The optimum photocatalyst loading for Degussa P25 was found to be 1.5 g L-1 while for Hombikat UV 100 was between 3.0-4.0 g L-1. The photoactivity of Degussa P25 is higher than that of Hombikat at lower photocatalyst loadings whereas it is lower at higher photocatalyst loadings. This was found both experimentally and also by mathematical modeling of the radiation within the photoreactor zone. The photoactivity of UV 100 titanium dioxide was found to be twice that of Degussa P25 at optimum loadings. </p>
