Authors: Kostiuk T. , Kaniura A.
Published: November 2021

The prevalence of dysfunction of the temporomandibular joint, especially in people aged 18-60 years, reached 95-98 % among all dental applications. The course of the pathology is usually hidden, with periodic recurrences and has a long nature, which is accompanied by a decrease in overall quality of life. Treatment of this pathology of the temporomandibular joint is a set of complex therapeutic, orthopedic and psychological measures. The literature describes many ways to treat temporomandibular joint dysfunction, one of the modem ones is the use of occlusal splints, which allow to change the position of the mandible, diagnose and eliminate musculoskeletal dysfunction of the temporomandibular joint. The aim of the study was to determine the effectiveness of treatment of musculoskeletal dysfunction of the temporomandibular joint with occlusal splints according to axiography. 274 patients aged 18 to 65 years were diagnosed with temporomandibular joint pain syndrome before and after treatment. All patients with signs of temporomandibular joint dysfunction before treatment had a violation of the trajectory of the mandible (deviation is 68.7 %, dyslexia is 31.3 %). When opening and closing the mouth, asymmetrical shifts of the lower jaw to the sides of more than 2 mm (deviation from the midline is more than 2 mm) were observed. After treatment with occlusal splints there was an improvement in the trajectory of opening and closing the mouth: the number of patients with a violation of the trajectory decreased by 89.1 %, and the displacement of the mandible during opening and closing the mouth in 92.4 % of patients decreased on average to 0.9 mm. When analyzing the movements of the mandible in the sagittal plane in 79 % of cases, deviations of the trajectory of the mandible were detected. After treatment with occlusive muscle relaxation splints, elimination of violations of the trajectory of the mandible in the transverse plane was noted in 93.4 % of cases, reduction of displacement to 0.9 mm in 78.1 % of patients. The trajectory of the mandible in the sagittal plane improved in 80.1 % of patients, normalization of the position of the mandible relative to the neuromuscular trajectory was achieved in 93.4 % of clinical cases. According to the analysis of parameters, such treatment should be considered effective.

COVID-19 OUTBREAK IN EUROPE AND ITS IMPACT ACROSS FOUR DIFFERENT SECTORS: ANALYTICAL RESEARCH
Authors: GIAMMANCO Maria Daniela , GITTO Lara
Published: November 2021

The ambition of this contribution is to outline how the European perspective – that of economists and social science scholars who have observed and studied Covid-19 in the last 16 months, has been represented in the more popular journals worldwide dealing with Agriculture, Education, Health and Tourism. The first two sectors, Health and Education, have been chosen because of the relevance of the merit goods provided, not only for the present wealth, but for the future development of society. Tourism has been selected because this sector has been savagely devastated by the pandemic due to the necessary restrictive governmental measures imposed to avoid the virus spreading. Agricultural sector plays an important role in the European economy especially for the countries with the lowest income.

The trend found among the considered journals, which were selected out of those with the highest h-index through the search engine Scimago, was to publish a few selected contributions or, oftentimes, to dedicate a special issue of the journal to the economic consequences of the pandemic. Since this survey is aimed at summarizing the European evidence, some of the identified studies were not considered, most of them concerning the Asian Far East countries (the geographic area from where the contagion began) and the USA (the country with the highest number of deaths due to Covid-19).

Authors: Belyaeva Svetlana N. , Pirogova Maria E. , Govorun Maria I.
Published: November 2021

BACKGROUND: Plant pollen can influence the climatotherapy and elimination therapy results of respiratory allergic diseases. Flora diversity and the poorly studied prevalence and etiology of pollinosis on the Southern Coast of Crimea determine the need for aeropalinological studies of this region to optimize the treatment and rehabilitation of patients with respiratory sensitization. AIMS: To determine the potentially unfavorable periods for the stay of patients with pollen sensitization on the Southern Coast of the Crimea and develop a plant pollination calendar of the Yalta resort MATERIALS AND METHODS: The research was conducted in the coastal and foothill area of Yalta in 20112013. The study determined the content of pollen in plants that are passively deposited from the air onto the glasses-traps using the gravimetric method. The taxonomic belonging of the pollen was established by collecting the plant pollen of the Southern Coast of Crimea. RESULTS: A total of 19 pollen taxa have been identified in the air of Yalta, of which 10 had sensitizing properties. Cypress (49.7% of pollen of the average annual amount) and most deciduous trees with allergenic pollen (4.7% of pollen) were intensively pollinated in MarchApril, Poaceae grasses (1.6% of pollen) in May, and weed grasses (1.6% of pollen) in late August to early September. Birch and alder pollen was not detected. On average, 2.2 times less pollen was detected in the coastal area air of the resort than in the foothill area. The plant pollination calendar of the Yalta resort has been developed. CONCLUSIONS: The intensive cypress pollination period in MarchApril is least favorable for patients with pollen sensitization to stay on the Southern Coast of the Crimea. Poaceae in May and weeds in late August to early September create an insignificant pollen load. A plant pollination calendar has been developed to predict unfavorable aeropalinological periods and optimize the treatment and rehabilitation of patients with pollen sensitization in the Yalta resort. The best conditions for the treatment and rehabilitation of patients with respiratory allergies have been identified in the coastal area of the resort. The absence of birch and alder pollen in the air contributes to the elimination therapy at the Yalta resort.

Mushroom can be served as flavoursome food, but most importantly, it can be served as nutritional and medicinal value food. Therefore, a mushroom is an essential commodity under the Malaysia National Agro-Food Policy. Currently, mushroom cultivation is being done in the conventional method, not in a proper and hygienic condition. Therefore controlled environment mushroom house (CEMH) has been developed by transforming a greenhouse into a controlled environment mushroom house integrated with the internet of things (IoT) system. This CEMH micro-climate is automatically controlled by the combination of data parameters provided by various types of sensors. The integration of the IoT system has further enhanced this system to overcome extreme weather changes and override the control anytime and anywhere. The computation and monitoring process can be done either locally or remotely. The current system is set up for Grey Oyster mushroom (Pleurotus pulmonaris) cultivation to identify the best isolate to be proposed for mass production. The interconnection of sensors, mechanical and electronic systems is to optimize the growth condition. The developed system manages to control the temperature consistently and relative humidity (% RH) in the range of 18oC to 27oC and % RH not lower than 70%, respectively. For this condition, this system can produce at least 30% more yield than ordinary mushroom houses. Moreover, the contamination rate is successfully kept below 2% and is considered very low compared to ordinary entrepreneur mushroom houses, usually more than 10%. This system can provide the research facility for the high nutritional and medicinal value mushrooms.
DEVELOPMENT OF THE COMBINED TECHNOLOGICAL PROCESS OF BLANK STACKS FLANGES FORMATION BY THE METHOD OF STAMPING BY ROLLING AND ROTARY DRAWING
Authors: Matviychuk Viktor , Kolisnyk Mykola
Published: November 2021

The article presents the results of the development and research of the combined technological process of forming the outer and inner flanges of the lids of fractional and distillation columns on sheet blanks by the method of stamping by rolling and rotary drawing. For this purpose, equipment has been developed that allows to form both outer and inner flanges of the blank in one run of the conical roll.

Studies have shown that technological capabilities of the process are limited by the risk of destruction of the top layers of the outer flange bending center and its corrugation, as well as by the neck formation or destruction of the peripheral areas of the inner flange. To assess the deformability of the outer flange, the stress-strain state of its bending center was investigated. According to the set stress values, the stress state of the material is determined, the maximum value of which on the surface of the bending zone is Formula for determining the minimum radius of the mandrel, which when using the values of the critical ductility of the material allows to prevent destruction. As well, an expression for determining the maximum width of the flange, provided that the destruction of peripheral areas is prevented, is obtained.

As corrugations formation is the main danger in forming the external flanges by the stamping by rolling method (SR), the expression for determining the maximum width of the flange under the condition of a stable process is obtained. If it is necessary to get more developed flanges, it is proposed to provide thinning of their walls by rotary extraction at the second stage.

When forming the inner flanges of the blank stacks radial compressive stresses and tangential tensile stresses in the material are brought about. The action of tangential stresses causes loss of stability of the flange by way of neck formation. The value of the critical strains increases with the approach to the state of plain-strain deformation. Therefore, it is recommended to develop process parameters based on construction of the critical strains diagrams.
CALCULATION ON THE STRENGTH OF DEFORMING ELEMENTS AND DEVELOPMENT OF FIRMWARE STRUCTURES FOR ULTRASOUND PROCESSING
Authors: Rutkevych Volodymyr , Kushnir Vitaliy
Published: November 2021

The possibility of increasing the efficiency and expanding the technological capabilities of the process of deforming drawing, by studying the contact phenomena and force characteristics of the process of deforming drawing (flashing) with the imposition of ultrasonic vibrations on the tool.

The main advantages of deforming drawing with application of ultrasound are noted, among which it is necessary to allocate considerable decrease in force parameters of process, reduction of level of residual stresses, increase of accuracy of the processed details. Also, the application of ultrasound allows you to process parts made of metal and alloys, the processing of which in normal conditions is impossible and requires special techniques. It is noted that it is not possible to use known designs of broaches and firmware when flashing with the application of ultrasonic vibrations, because the firmware must have all the dimensions related to the acoustic parameters and the deforming element must be placed on the mandrel with tension to create good acoustic contact between the mandrel and the element.

Prefabricated deforming firmware for processing holes with the imposition of longitudinal ultrasonic vibrations has been developed and a method for calculating their deforming elements for strength has been proposed. The performed calculations showed that the calculated stresses differ from the allowable ones by no more than 15-20 %. From the above calculations it is seen that the deforming element can be destroyed, both under the action of the working load in the process of flashing, and under the action of thermal stresses after the exit of the element from the machined hole. This difference in the results of research can be explained by the fact that the order of tensile strength is a value that has a large scattering zone and in different studies it is different.

The results of research on the strength of deforming elements can be used in engineering calculations in the design of prefabricated tools for drawing holes with ultrasound.
EXTRACTION OF MINERAL RAW MATERIALS OF A GIVEN SIZE AND DENSITY FROM ROCK MASS BY THE VIBRATION METHOD

Published: November 2021

Vibration processes are widely used in technology in the processing of bulk materials to improve the efficiency of such operations as transportation, mixing, separation by size and material composition and compaction. Theoretical studies of the processes of vibration displacement of particles in granular media under the influence of vibration are presented by a large number of mathematical models, but many of them need to be compared with experimental data. Practical interest is the determination of the time of ascent of relatively large or densest particles to the surface of a layer of crushed rock mass under the action of the vertical vibration component. The article presents the results of an experimental study of this process. A set of experiments on the extraction of basalt particles from tuff rock mass (waste from basalt quarries), ferruginous quartzites from the mass of dump rock, and relatively large granite particles from crushed granite mass was performed. Processing of the experiments using the SPSS Statistics program allowed us to analyze the process and obtain regression models for determining the time of ascent of a particle of a given size and density from the rock mass, including two generalized regression models. In the first of them, the variables were the amplitude and frequency of vibration, the particle size of the medium was 25 mm, the particle density of the medium was 1.6-2.8 g/cm3, the particles floating under the action of vibration have a particle size of 50 mm, their density varies from 2.5 to 5.1 g/cm3. In the second model for А= 5 мм, w=30 Гц, an additional variable factor is the size of the floating particle, which varies from 50 to 25 mm The resulting equations allow us to determine the time of ascent and predict the extraction of particles of a given size and density under the influence of vibration, for example on the conveyor belt, without conducting cumbersome experiments.
OSCILLATIONS OF A PULSE LOADED OSCILLATOR WITH A SQUARE RESISTANCE IN THE COMPOSITION OF THE DISSIPATIVE FORCE
Authors: Olshanskiy Vasyl , Slipchenko Maksym , Tverdokhlib Igor , Kupchuk Ihor
Published: November 2021

The unsteady oscillations of a dissipative oscillator caused by an instantaneous impulse of the force are described. The case is considered when the dissipative force consists of quadratic viscous resistance and dry friction, and the theoretical results are generalized to the case of the sum of three forces. The third is the force of positional friction. Formulas for calculating the ranges of oscillations have been constructed In this case, the Lambert function of negative and positive arguments is used. It is a tabulated special function. Its value can also be calculated using its known approximations in elementary functions. It is shown that, due to the action of the dissipative force, the process of post-pulse oscillations consists of a finite number of cycles and is limited in time. This is due to the presence of dry friction among the resistance components. Examples of calculations that illustrate the possibilities of the stated theory are given. In order to check the reliability of the derived calculation formulas, numerical computer integration of the differential equation of motion was also carried out. The convergence of the numerical results obtained by two different methods is shown. Thus, it has been confirmed that with the help of analytical solutions it is possible to find the extreme displacements of the oscillator without numerically solving its nonlinear differential equation of motion. Using Lambert function and the first integral of the equation of motion made it possible to derive precise calculation formulas for determining the range of oscillations caused by the pulsed load of the oscillator. The derived formulas are suitable for calculating the value of the instantaneous impulse applied to the oscillator, which refers to the inverse problems of mechanics. Thus, by measuring the maximum displacement of the oscillator, it is possible to identify the initial velocity or instantaneous impulse applied to the oscillator. The performed numerical computer integration of the output differential equation confirmed the adequacy of the obtained analytical solutions, which concern not only direct, but also inverse problems of dynamics.

The peculiarity of harvesting legumes is the need to process their heap on grater devices with subsequent separation. To improve the technical and economic performance of seed heap processing equipment, it is advisable to combine wiping and separation operations by combining a grater working body and a separating rotating sieve of cylindrical or conical shape. The analysis of influence of geometry of rotary sieve drums allows to define the rational form and parameters of work of the separating device which will provide the necessary quality of seed material.

Analysis of the literature on the processes of sieve separation of grain and seed mixtures showed the advantages of centrifugal separators with a rotating sieve surface. Improving the efficiency of separation of mixtures by rotary sieves is achieved by the simultaneous use of centrifugal, Coriolis and gravitational forces.

The aim of the study is to increase the efficiency of separation of seed heaps of legumes after treatment with a grater device by determining the trajectory of the seeds along the rotational surfaces. Earlier, the authors developed a grater-separating unit in which a cylindrical perforated drum is used to remove unworn seeds. This design does not use the surface of the sieve effectively enough. To increase the uniformity of the load on the steaming surface of the rotary drum, it is advisable to reduce its area in the direction of seed movement. To do this, use a conical separating surface to reduce the radius of the cone in the direction of movement of the material.

When considering the movement of a particle, it is represented as a material point with mass m moving along a conical surface that rotates around a vertical axis. As a result of theoretical researches the dependence which defines time of stay of a particle on a sieve depending on a coordinate (length of a generating cone) is received. A graphical interpretation of this dependence for certain values of design parameters is also presented.

As a result of research, it was found that increasing the residence time of the material on the sieve due to the use of a conical surface increases the yield of pure seeds, and also contributes to the uniform loading of the sieve surface, which improves the quality of the source material.

Multi-choice programming problems arise due to diverse needs of people. In this paper, multi-choice optimisation is applied to bilevel transportation problem. This problem deals with transportation at both the levels, upper as well as lower. There are multiple choices for demand and supply parameters. The multi-choice parameters at the respective levels are converted into polynomials which transmute the defined problem into a mixed integer programming problem. The objective of the paper is to determine a solution methodology for the transformed problem. The significance of the formulated model is exhibited through an example by applying it to a hotel industry. The fuzzy programing approach is employed to obtain the satisfactory solution for the decision makers at the two levels. A comparative analysis is presented in the paper by solving bilevel multi-choice transportation problem with goal programming mode as well as by the linear transformation technique proposed in the paper by Khalil et al. The example is solved using computing software.

Traditional Chinese medicine recommends kidney-tonifying treatment for osteoporosis. Zuogui pill is one such treatment composed of eight well characterized Chinese medicinal herbs (Radix rehmanniae preparata, Fructus lycii, Rhizoma dioscoreae, F. corni, Semen cuscutae, Colla cornus cervi, C. carapacis et Plastri testudinis, and R. achyranthis bidentatae). The aim of the study is to evaluate the effects of the Zuogui pill on osteoporosis in ovariectomized rats and to identify the signaling pathways that mediate its action on the bones. A total of 46 6-month-old female Sprague-Dawley rats were divided into four groups: sham-operated control, bilaterally ovariectomized, ovariectomized rats receiving diethylstilbestrol (the positive control group), and ovariectomized rats receiving the Zuogui pill. By the end of 8-week treatments, the following parameters were assessed: (a) bone mineral density and trabecular histomorphology, (b) the expression levels of receptor activator of nuclear factor kappa B ligand and osteoprotegerin in rat tibial osteoblasts and (c) bone marrow stromal cells. The Zuogui pill treatment elevated the trabecular bone area and trabecular thickness and reduced the trabecular spacing in rats with ovariectomy-induced osteoporosis. Compared to the ovariectomized group, the Zuogui pill treatment significantly increased the levels of bone mineral density and osteoprotegerin and suppressed the level of receptor activator of the nuclear factor kappa B ligand. These data led us to conclude that the Zuogui pill regulates bone metabolism and improves osteoporosis symptoms possibly through the osteoprotegerin/receptor activator of the nuclear factor kappa B ligand/receptor activator of the nuclear factor kappa B signaling pathway.
