The feasibility of using red mud in coatings based on glyptal resins

The possibility of industrial waste – alkaline red mud to be used as the filler of glyptal resins and coatings thereof is considered. It was determined that the most effective way of compounding of said components was in situ combinations during the synthesis of the polymer, providing systems with filling factor up to 36 wt.% with decreased moisture absorption ability in comparison to the initial resin. It was demonstrated that the most probable cause of this performance increase is the formation of chemical bonds between the hydroxyl groups of glyptal and weak van der Waals bonds between the carbonyl group of the resin and surface groups on red mud

Study of the steering of a wide span vehicle controlled by a local positioning system

Controlled traffic farming allows to minimize traffic-induced soil compaction by a permanent separation of the crop zone from the traffic lanes used by wide span tractors. The Authors developed an agricultural wide span vehicle equipped with a skid equipment for turning and an automatic driving system prototype based on a laser beam. The aim of this work was to study the kinematic conditions that control the steering of this machine. Furthermore, the accuracy and the maximum delay time of the signal transmission by the automatic driving system of the set-up was also assessed. In comparison with crawler tractors, the turning of the agricultural wide span vehicle needs a smaller difference in the moments applied to its right- and left-side wheels. For the predetermined accuracy of the beam position relative to the plant rows, ±ds = ±0.025 m, the accuracy of the direction of the laser beam at a distance S=200 m should not be more than ±0.07° and ±0.0014°, considering a run length of 1000 m. Furthermore, at a speed V=2.5 m s–1 a trajectory deviation φ≤5° requires a topmost delay time of the control signal of Δtmax=0.11 s is required

Saabunud / Received 28.10.2021 ; Aktsepteeritud / Accepted 10.12.2021 ; Avaldatud veebis / Published online 11.12.2021 ; Vastutav autor / Corresponding author: Andrii Melnyk [email protected] experiment aimed to evaluate the effect of different compound regulators on the germination rate, seedling morphology of two mustard (Brassica juncea L.) cultivars ('Felicia' and 'Prima') under simulated drought stress with PEG-6000. The eight commercial growth compound regulators (ALBIT, VERMISTIMD, ANTISTRESS, AGRINOS, REGOPLAN, BIOFOGE, STIMULATE, and FAST START) were pretreated seeds at recommended doses. The application of growth regulators promoted the growth of seedlings under drought stress but had no obvious effect on the germination rate of the two varieties. The root fresh weight, total root length, leaf area, stem length, and stem volume in 'Felicia' significantly increased with ANTISTRESS treatment by 24.28, 3.30, 24.70, 19.40, and 30.90%. In addition, the number of lateral roots reached the maximum with AGRINOS and REGOPLAN treatment compared with plants without regulators under drought conditions, which were 135.55 and 121.20%, respectively. For 'Prima', the application of FAST START had a remarkable effect on root fresh weight, total root length, lateral root number and primary root length, root surface area, leaf area, and stem volume by 17.62, 18.12, 211.20, 53.75, 28.57, 15.90, and 32.30%, respectively

Criminological Assessment of Medical Misconduct during the COVID-19 Pandemic

This study examines the professional actions of health workers during the spread of the COVID-19 pandemic from the point of view of criminological assessment in the context of labor relations. With the help of political and legal analysis and a comparative legal method, the work considers the international practice of assessing the actions of medical workers from the standpoint of criminal responsibility, political and legal initiatives concerning the protection of the rights of medical workers during the spread of a pandemic and quarantine measures. This study argues for significantly broader criminal immunity for health workers during a pandemic. At the same time, the study gives grounds to assert that today the lack of sufficient empirical data and research complicates an objective assessment of the offender. At the same time, based on the results of this study, it is suggested that in the near future the number of investigations and appeals to the court on issues related to the professional activities of medical workers carried out during the spread of the pandemic will increase.

CLINICAL ASSESSMENT OF MANAGEMENT WHEN CHOOSING A METHOD OF PROVIDING CARE TO PATIENTS WITH OPEN-ANGLE GLAUCOMA

Introduction: glaucoma is an essential international social and medical problem, as it leads to irreversible blindness in patients worldwide. Organization of treatment and prevention of complications using the most effective methods is the most important task of ophthalmologists at the present stage of the fight against glaucoma. The purpose of the study: to evaluate the management of assistance under the monitoring program «STOP! Glaucoma» to patients with suspected glaucoma, open-angle glaucoma, and more advanced stages of glaucoma. To compare the effectiveness of therapeutic and surgical methods of glaucoma treatment. Materials and methods: To detect and prevent the progression of glaucoma in patients, the LLC «VISIOBUD» Clinic developed and implemented the monitoring program «Stop! Glaucoma». The main task of program was to analyze the dynamics of glaucomatous changes in the optic nerve and, based on this, to determine whether glaucoma compensation is complete and whether the patient does not need a more radical treatment method to preserve visual functions. The following methods of empirical research were used: systematic approach - to determine the research elements between which there are relationships of objects and their properties; observation - to identify signs and external manifestations of facts; comparison – to determine similarities and differences and identify regularities; measurement; monitoring. Results: In the course of the study, the dynamics of changes in intraocular pressure in patients who follow the annual monitoring program «Stop! Glaucoma» in the clinic of LLC «VISIOBUD». 4 groups of patients (116 patients – 156 eyes) were under observation. Installed that in 75% of cases, patients need surgical treatment of glaucoma to preserve their visual functions. Surgical treatment of patients with open-angle glaucoma effectively preserves vision in 89% of cases. Conclusions: Timely detection, monitoring, and treatment of initial signs of open-angle glaucoma and symptoms of its progression affects the preservation and prolongation of visual functions in patients. In the long term, surgical treatment of glaucoma is more cost-effective, as the need to use expensive hypotensive drops is significantly reduced (by 2.5 times)

Coupling between Geomagnetic Field and Earth’s Climate System

The idea about synchronized variations of geomagnetic field and climate appears in the middle of the twentieth century. Among others, one of the main reasons for its unpopularity is the missing mechanism of coupling between magnetic and non-magnetic media. This chapter offers such a mechanism, consisting of a chain of relations transmitting the geomagnetic spatial-temporal variations down to the planetary surface. The first element of this chain is energetic particles propagating in Earth’s atmosphere, whose density and depth of penetration are modulated by geomagnetic field. Thus, the non-dipolar geomagnetic irregularities are projected on the ionization layer in the lower atmosphere (known as Regener-Pfotzer maximum). This unevenly distributed ionization, in certain conditions (i.e. dry atmosphere), acts as a secondary source of ozone near the tropopause. Ozone at this level is of special importance due to its influence on the tropopause temperature and humidity, and consequently on the planetary radiation balance. Hence, the geomagnetic spatial and temporal variations are imprinted down to the surface, impacting the climate system and its regional structures. The chapter provides synthesized information about geomagnetic field variability, particles’ propagation in Earth’s atmosphere, ion-molecular reactions initiating ozone formation in the lower stratosphere, as well as evidence for its covariance with some atmospheric variables

Analysis of Tongue Color-Associated Features among Patients with PCR-Confirmed COVID-19 Infection in Ukraine

Objective: To evaluate and systematize tongue color-related manifestations among patients with PCR-confirmed COVID-19 infection. Material and Methods: This retrospective study included analysis of tongue images obtained from patients with PCR-confirmed COVID-19 infection. Evaluation of coronavirus disease severity (mild, moderate, severe, critical) was provided, considering clinical symptomatology and results of laboratorial and instrumental diagnostic methods. Each picture was analyzed considering the parameters of color of the tongue and color of the tongue plaque by two dental specialists. Cochran-Armitage test for trend was used to evaluate associations between the tongue color and tongue plaque color, and coronavirus disease severity. Results: The most prevalent tongue colors were pale pink, red and dark red (burgundy color). A total of 64.29% of patients with mild disease demonstrated pale pink color of the tongue. Patients with moderate coronavirus disease were characterized with the adverse trend: 62.35% of them presented with red-colored tongue, while in 37.64% of cases, the tongue was pale pink. Severe COVID-19 patients, almost in 90% of the cases, had either red or burgundy color of the tongue. Conclusion: SARS-COV-2 infection is not manifested by tongue-targeted or tongue-specific signs and features; however, coronavirus disease itself provokes changes within the tongue color and tongue plaque color similar to those registered during other internal pathologies
