The Palatine tonsils are peripheral organs of the immune system. B-dependent and parafollicular T-dependent zones represent Their lymphoid tissue. A feature of the Palatine tonsils is the close connection of the lymphoid tissue with the integumentary epithelium, reflecting the intercellular interaction of lymphocytes and epithelial cells in the immuneresponse. The various local treatment methods of chronic tonsillitis are used, which in most cases do not prevent the development of acutetonsillitis and paratonsillar abscesses even in the shortest possible time after treatment. Therefore, the search for new methods of treatment of chronic tonsillitis is still an urgent problem

Today, the COVID-19 pandemic is one of the most pressing problems facing humanity. Therefore, reducing the population's level of infection with this virus is one of our government's main tasks.Therefore, it is necessary to isolate patients with chronic diseases as much as possible. Clients are more likely to be infected with caronavirus due to their age and the presence of underlying medical conditions.Limiting direct contact between such patients and observing healthcare professionals significantly reduces the patient's chances of contracting caronavirus.The article proposes a device design that allows for remote automatic monitoring of patients' condition being treated at home by an observing medical professional.With the proposed device's help, the patient's blood oxygen saturation level is automatically and remotely controlled. The device is built on an Arduino board.The use of the device greatly reduces the likelihood of contracting caronavirus in patients receiving home treatment.This could be one of the most important decisions in maintaining the health of the population today.

Age-related macular degeneration (AMD) is a progressive eye disease in which the physiological function of the choriocapillaries, Bruch’s membrane, and retinal pigment epithelium (RPE) areimpaired, a defect in the photoreceptor layer occurs, and central vision is irreversible. Primary open-angle glaucoma (POAG)is a pathological process characterized by impaired hydrodynamicsof intraocular fluid and damage to the optic nerve, althoughthe anterior chamber angle is open. In this disease, intraocular pressure (IOP) often increases and peripheral vision decreases depending on the retinallayer's level of compression. According to WHO statistics, POAG is then complicated by the “dry” form of AMD in 41% of cases, i.e. an effectivecombination of the above two pathologies can be observed in clinical practice. Consumption of foods rich in antioxidant micronutrients and drugslikes“Ophthalmocomplex” in the prevention and treatment of chronic degenerative eye diseases such as primary open-angle glaucoma (POAG) and age-related macular degeneration (AMD) can shorten the rehabilitation period. Themechanisms of development of pathologicalprocesses (especially inflammation, degeneration) are different. Still,the main pathogenetic point is the disruption of the antioxidant defense system as a result of detoxification.Keywords: age-related macular degeneration (AMD), primary open-angle glaucoma (POAG), vitamins, antioxidants, partially oxidized free radicals, Ophthalmocomplex drug, healthy eating

Arterial hypertension (AH)is currently considered the most significant risk factor for the development of not only acute cerebrovascular accidents and chronic cerebral ischemia, but also disorders of memory and other cognitive (cognitive) functions. Numerous studies have proven the connection between persistent increase in blood pressure (BP) and the risk of the onset and progression of cognitive impairment. The positive dynamics on the part of clinical and hemodynamicparameters is explained by the fact that gliatilin improves thetransmission of nerve impulses in cholinergic neurons; positively affects the plasticity of neuronal membranes and receptor function. Gliatilin improves cerebral blood flow, enhances metabolic processes in the brain, activates the structures of the reticular formation of the brain and restores consciousness in traumatic brain lesions.

Viral infections are responsible for 15–20% of all human cancers. Infection with oncogenic viruses can contribute to various stages of carcinogenesis. Despite effective screening methods, cervical cancer continues to be a major public health problem. There are large differences in morbidity and mortality from cervical cancer by geographic region. The age-specific prevalence of HPV varies widely in different populations and has shown two peaks of HPV positiveness in young and older women. Around the world, there have been many studies on the epidemiology of HPV infection and oncogenic properties due to different HPV genotypes. However, there are still many countries where population prevalence has not yet been determined. Moreover, screening strategies for cervical cancer differ from country to country. Organized cervical screening programs are potentially more effectivethan opportunistic screening programs.Key words:Human papillomavirus, cervical cancer, screening, dysplasia

Authors: Woldeyesus Solomon Kassa , Endris Mohammed Yimam
Published: October 2021

This article examines the discursive strategies, the ideological dominations and interrelated material tools employed by the Tigray People’s Liberation Front (TPLF) in maintaining its rule. It also unravels the hegemonic crisis it has encountered, and the counter-hegemony it has confronted since 2015. Gramscian novelties of historical bloc, hegemony, organic crisis, counter-hegemony, and interregnum, are deployed in order to understand the continuities, ruptures and crises witnessed in Ethiopia’s politics for the past thirty years. The article interprets the crisis of the TPLF since the 2015 protests through the prism of organic crises and analyses the counter-hegemonic contestations, the interregnum and the ongoing war since 4 November 2020. The article adds to the recent resurgence of interest in Gramscian perspectives by demonstrating the relevance of Gramscian concepts to the understanding of politics in the states of the global south.
LEVELING IMPLEMENTS USED FOR DEVELOPING AND CLEANING RECLAMATION CANALS
Authors:   Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, MIRONOV ALEKSEI V.
Published: October 2021

Effi cient performance of agricultural operations requires the active use of reclamation systems, e.g., bypass canals. One of the main factors that reduce the quality of reclamation is the accuracy of positioning the soil profi le when cleaning or arranging canals. Excavating equipment is used to develop reclamation canals. Modernization of excavators by introducing automatic leveling systems (ALS) into their design can increase performance, accuracy, and, therefore, productivity. The authors consider three principal solutions of the ALS design during the operation of excavators: ALS2D control system, ALS satellite control system, ALS AUTO satellite leveling system. Field tests were carried out at the test site to check the quality of the embankment erection with a JCB JS205 excavator with the ALS. The data obtained were compared with the indicators of blading with a JCB JS205 excavator without the ALS. The research results showed that the most advanced option was the ALS AUTO satellite leveling system since the quality of the work performed practically does not depend on the human factor. Also, the excavator with the ALS AUTO satellite leveling system proved to have a lower deviation angle of the developed embankment from the design-specifi ed angle per 1 sq. (2.4%) as contrasted to the ALS2D control system (8.3%) and the ALS satellite monitoring s ystem (6%). The excavator without the ALS demonstrated a value of 11.1%. Therefore, it is advisable to modernize excavators by introducing the automatic leveling system, which will increase the performance by 200% and double the accuracy of the work performed.
TESTING THE HYPOTHESIS OF THE COSINE DISTRIBUTION OF STRESSES IN THE SHAFT-HOLE CONTACT
Authors:   Bryansk State Agrarian University, BEZIK DMITRY A.
Published: October 2021

One of the most common connection types in mechanical engineering and construction is the shaft-hole connection. The mechanical stresses caused by its loading are distributed in the contact zone of the loaded parts of the joint. In some cases, they can lead to destruction. Therefore, while designing, it is important to analyze the mechanical stresses in the contact zone. Traditionally, calculations assume that the contact stresses are distributed according to the cosine law. However, this is not entirely true, especially with diff erent shaft and hole diameters. The authors examined theoretical studies of the contact zone of the shaft and the hole (including the cases of diff erent diameters) and the stress distribution in the contact zone. Based on the studies, they performed numerical calculations in the APMWinMachine environment to determine the stresses in the volume of the shaft and the plate with a hole when loading the shaft-hole connection. The analyses were performed for the two-dimensional case by the fi nite element method in the APMStructure program. The results show that when the diameters in the connection are equal, the stress distribution is close to the cosine law. In this case, only one stress raiser occurs in the contact zone, which is located on the line of action of the loading force. However, if there is a slight discrepancy in the shaft and hole diameters, there are three stress raisers in which the connection may break – the central zone and two side zones. The angular distance between them can be determined based on the known theoretical formulas. The authors made an experiment with a plexiglass model, which qualitatively confi rmed the correctness of the analysis performed.

Published: October 2021

The article is devoted to the problem of educational institutions' heads’ academic diplomacy development by creative cooperation means. The main task of educational diplomacy in forming the educational institution image and all participants' interpersonal relations in the educational process is substantiated. The attention is focused on the educational institutions' heads' communicative activity as a phenomenon and creativity pedagogy subject; the educational institutions' heads' creativity directions are substantiated; considered the concepts theoretical content of «diplomacy», «communicative culture», «educational diplomacy», «creativity»; diagnostics the readiness of educational institutions' leaders and teachers for the educational diplomacy development as a tool for the creativity pedagogy was carried out. The diplomatic qualities of the leader and teachers of an educational institution are characterized, which provide an opportunity for the manifestation of their own creative abilities and characteristics, which encourage the creative potentials to be processed in a high-quality, enrich them with mental new formations, creative activity experience, and creative abilities, and also develop communicative interaction.

The direction of interaction between the educational process participants on the dialogue basis and the head preparation for the creation of psychological and pedagogical conditions, concerning the creative educational activity of students, with educational diplomacy application, communication methods and receptions of their creative activity is defined. Pedagogical creativity occupies a special place among different types of creativity, because it determines the dynamic development vectors of mankind all creative processes, and the creative nature development is determined by communication and increase in communicative culture. The peculiarity of any communicative process – the process as a result of which a qualitatively new one is created – is that not only man, the creator influences his own creativity result, but also the subject of creative interaction contributes to further human development. That is why in the pedagogical interaction process the creative development of the educational institutions' heads is both their activity purpose and the creative development means of the leader's personality, increasing his professional competence and communicative skills level. Thus, creativity leads to professional and personal self-realization of the leader in the management process.

Authors: Melnyk Inna
Published: October 2021

The article is devoted to the problems of psychological and pedagogical training. The urgency of the problem is due to lack of knowledge in society about effective mechanisms for maintaining, strengthening and restoring mental health in conditions of constant physical and intellectual overload, stress, social unrest, as evidenced by numerous facts of nervous breakdowns and psychosomatic diseases. The article highlights the quantitative and qualitative results of an empirical study of the psychological component of health competence in future teachers according to certain criteria - cognitive, motivational-value, activity and reflexive. The indicators of each of these criteria are described, as well as the used diagnostic tools for their study are described. It was found that the respondents do not have a high enough level of formation of the psychological component of health competence according to cognitive and reflexive criteria, which indicates the need for intensive work on the formation of deep knowledge of future teachers on the essence of "mental health" and ability to reflect in order to preserve and strengthen their own mental health and the health of children. Based on these results, the main ways and prospects for improving the level of formation of the psychological component of health competence of students on cognitive and reflexive criteria in the process of studying the course "Psychological Anthropology" were identified.

Published: October 2021

Given the importance of overcoming the shortage of staff in the STEM market, this study aims to present the analysis in terms of gender characteristics that affect the choice of profession by high school students. The sociological survey was conducted using the online method - a survey using Google Forms service. Four hundred and thirty-one respondents were 11th grade students (including 230 girls and 201 boys) who studied in experimental secondary schools in Dnipropetrovsk region participated in the survey. The methodology covers such aspects, as students’ knowledge of mathematics and natural sciences; career interests in the context of students’ motivation in studying STEM disciplines; students’ knowledge of the requirements for STEM careers. In the research, by comparing the answers of male and female respondents, it became possible to draw parallels on gender differences in the field of professional preferences of the surveyed students in the context of STEM education. Thus, after conducting research on gender specifics that influence the choice of profession in STEM areas by high school students, we can talk about the following. The obtained results show that there are insignificant differences between girls and boys in the field of interest in natural and mathematics sciences and technological education with an advantage in favor of boys. The results suggest that the choice of profession by high school students in the field of STEM is influenced by awareness of the prospects of the future career and self-confidence, which is connected with students’ academic success in mathematics, science and technology education. The study is one of the pilot projects in Ukraine. To further delve into the problem, it is necessary to conduct a regression analysis of several variables, in particular, the study of the relationship between career planning in the field of STEM and the type of residence of students (metropolis, city, town, village) and analysis of STEM preferences with reference to academic success of boys and girls.
INTERNAL MOTIVATION OF STUDENTS AS A PRIORITY COMPONENT OF LEARNING TO PLAY THE PIANO
Authors: Bondarenko Anasasya , Nalyvaikoa Oleksii
Published: October 2021

The article deals with the need for the formation of internal motivation as one of the most important components of pedagogical activity in teaching piano, which is based on the development of creative individuality of the student and provides a constant need to share emotional experience. Establishing such communication, mediated by a work of art, the "sensory fabric" of which is unfolded in time, concerns the immediate environment and circulation of the experience of previous generations with the constantly updated impressions of a student-musician who is faced with the world of classical piano music. On the basis of a deep inner interest, which can develop into a passion for the process of mastering the instrument, a special language of auto-communication is built, a sensitive attitude to one's own feelings, which is later reflected with the help of the musical language. This contributes to an increase in the general level of reflexivity and awareness, and therefore there is a natural shift in focus on the development of the student's personality in the context of solving urgent problems of mastering playing the instrument. The focus on getting pleasure from playing music arises as a guarantee of high-quality mastery of the skills necessary for creative self-expression. The work analyzes the research of domestic and foreign scientists. The authors give recommendations for increasing the level of intrinsic motivation in the process of learning to play the piano. The paper concludes that the main factors that affect the increase in the level of intrinsic motivation are the building of harmonious relationships in the learning process. To do this, the authors propose to expand the range of psychological and pedagogical training of teachers of musical art on the basis of studying the current state of psychology and behavior of student, introducing digital teaching tools in the process of mastering the piano as a condition for rapprochement between different generations

Estimating Attention Level from Blinks and Head Movement
Authors: Goto Masaaki , Tanaka Tetsuo , Matsumoto Kazunori
Published: October 2021

In this paper, we develop a real-time method for estimating the level of attention while performing a task. This method uses only a low frame rate video from a standard camera so that it can be available even on a small computer. Eye blinks and head movements are calculated from a video by using landmarks. Existing blink detection methods use standard frame rate videos, making them difficult to process on a computer with low processing performance. One obvious solution is to use videos with a reduced frame rate. We investigate the error caused by reducing the frame rate, and then to overcome the error, we further develop a new method that uses the head movements calculated from the reduced frame rate videos. Then we demonstrate the error is within acceptable ranges by using the method, and show it is effective to estimate the attention level. Since this method uses only landmark information obtained from facial images, it reduces the mental burden on the user, and also partially protects personal information. In this paper, we explain the details of the method and report the experimental results.

Challenge of polymers for biosimilar products packaging
Authors: Anupam Chanda
Published: October 2021

Presently Packaging plays a significant role for Biosimilar product. The process of selecting materials and the type of packaging also offers an opportunity for the Packaging scientist to look for new biological delivery choices. Most injectable protein products were supplied in some sort of glass vial, prefilled syringe, and cartridge. Those product having high Ph content there is a chance of “delamination “from inner surface of glass vial. With protein-based drugs, the biggest issue is the effect of packaging derivatives on the protein’s three-dimensional and surface structure. These are any effects that relate to denaturation or aggregation of the protein due to oxidation or interactions from contaminants or impurities in the preparation. The potential for these effects needs to be carefully considered in choosing the container and the container closure system to avoid putting patients in jeopardy.

Fractures induced in twenty-five local breed rabbits, immobilization achieved by using Steinman intramedullary pins, which was not removed during the period of study for 7 weeks. 

Irradiation with LPL was made by direct contact between the source and the site of fracture directly after the operation and then daily for fifteen days. 

Each fracture was studied radiologically after the first day from the operation until complete healing occurs. 

This study confirm that the healing of distal third of tibial fracture was very slow in control group and LPL accelerate the process of fracture healing in treated groups. 

With notice that the surface of fractured bone exposed to the source of laser therapy (medial side) was healed better than the non - exposed surface (lateral side). 

Finally there was no clear difference between treated groups.

Cyproheptadine hydrochloride is a very high potent histamine and serotonine antagonist. This study was conducted to investigate the role of cyproheptadine on feed intake, body weight gain, feed conversion ratio, serum total protein, cholesterol and glucose. Red blood cells (RBC), Hemoglobin (Hb), Packed Cell Volume (PCV) and differential leukocytic count in blood of chickens were also estimated. A total of 60 one-day-old Fabro chicks were randomly divided into 2 groups. One group was received cyproheptadine at a rate of 10 ug / 100g body weight daily for eight weeks and the second group was used as a control. 

The results revealed that cyproheptadine could stimulate feed intake and improve body weight gain in chickens. Erythrocyte count, hemoglobin content and PCV where increased significantly in these chickens accompanied by an increase in percentage of lymphocytes with a significant decrease in percentage of heterophiles and H / L ratio. This drug also reduces the total protein, cholesterol and glucose in serum.

Indonesia merupakan negara kepulauan yang memiliki banyak wilayah yang sulit dijangkau, terutama di daerah perbatasan atau rural. Selain itu ketidaksetaraan distribusi penduduk dan ekonomi membuat pembangunan infrastruktur Teknologi Infomasi dan Komunikasi (TIK) secara keseluruhan di Indonesia tidak merata. Provider penyedia Telekomunikasi dan layanan internet di Indonesia belum dapat memenuhi kebutuhan infrastruktur di daerah terpencil. Solusi komunikasi yang berkembang cepat dan tanpa infrastruktur adalah MANET. MANET adalah sekumpulan node nirkabel yang bekerja sama membentuk jaringan. MANET terbentuk dari sekian banyak host yang terkoneksi melewati router tanpa inftrastruktur yang tetap dan berubah–ubah.  Pada pengujian dengan 5 node, kemudian dilakukan analisis QoS dengan standarisasi TIPHON, didapatkan nilai Sangat Bagus Ketika diuji dengan paket 1500 dan 2000 byte mendapatkan nilai indeks lebih dari 3 di Delay, sedangkan Jitter mendapkan nilai Sangat Bagus disemua pengujian dengan nilai indeks diatas 3.  Sedangkan Packet Loss mendapatkan nilai Sangat Bagus pada pengujian paket 1000 dengan nilai dibawah 3, pada pengujian throughput mendapatkan nilai TIPHON Sangat Jelek. Performa MANET dengan routing Babel layak digunakan model komunikasi alternatif karena masih mendapatkan nilai Sangat Bagus pada beberapa pengujian.

The article presents the results of a four-year collection study of promising varieties of spring-sown vetch, Vicia sativa L., for zoning in the conditions of the south-eastern zone of the Kamchatka Territory according to statistical parameters. The aim of the study was to identify stress-resistant, environmentally plastic, stable and adaptive varieties of vetch seed calculated by the yield of green mass. The experimental field of the Kamchatka Research Institute of Agriculture is located in the area of the Pacific influence with a cold summer without a dry season. Hydrothermal conditions during the periods of green mass formation in 2014-2017 were characterized by excessive moisture content, hydrothermal coefficient = 2.0-4.6. The environmental index ranged from -12.08 to 13.2. The correlation analysis revealed a direct relationship between the total yield and the sum of active temperatures, r = 0.9. An inverse correlation was determined between the environmental conditions index and the hydro-thermal coefficient, r = -0.79. The average annual yield of green mass for 4 years was 18.7 t/ha. The level of the average yield of green mass varied from 10.0 to 26.8 t/ha, the limit values varied within 5.5-34 t/ha. In the course of work, 18 varieties of spring vetch were studied, of which 5 valuable varieties were identified for cultivation in the region: Lyudmila (Yср = 26.8 t/ha), Yubilejnaya 110 (25.5), Uzunovskaya 91 (22.8), Tayozhnaya (21.8) and the zoned variety Lugovskaya 85 (18.0 t/ha), capable of producing stable yields in favorable and extreme conditions.

The work was carried out on the basis of the laboratory physiology of fruit plants resistance of the Russian Research Institute for Fruit Crop Breeding (VNIISPK) in 2019-2020. The objects of study were selected seedlings of red currant selection of the Institute. The method of artificial leaves dehydration was used for determination the drought resistance. The purpose of study was study indicators of water regime of selected seedlings of red currant in connection with their drought resistance. The water content, water deficiency, and the ability to restore water content after stress were determined. The Jonkheer Van Tets variety was use, as a control variety. In the result of study the indicators water regime of leaves in field conditions, the average level of water content was determined in the most hybrid forms of red currant. The lower level of leave water content was shown in July in compare to June, because there was an intensive outflow of water to the berries during the period of mass fruiting. In the field conditions, with sufficient plant moisture, red currant hybrids had a low water deficiency of leaves. After drought modelling, the water deficiency was increased in all the samples. The minimum amount of water deficiency in June and July under artificial conditions was found in red currant hybrids 2466-46-23. After modeling the drought and water saturation after that, select seedlings 2466-46-23, 2466-46-27, 2503-47-68, 2504-47-131, 2506-47-34, 2506-47-36, 2506-47-51, 2521-48-94 were characterized by a consistently high ability to restore the water content of the leaves. According to the results of the study some indicators of the water regime of red currant, was identified. the drought-resistant form 2466-46-23. The average level of drought resistance was shown in 2466-46-27, 2503-47-68, 2504-47-131, 2506-47-34, 2506-47-36, 2506-47-51, 2518-50-33, 2520-50-33, 2521-48-94.

The pandemic of the new coronavirus (COVID-19) disease that began in December 2019 in China is still having a huge impact on all spheres of human life. The herd immunity, which is the most effective tool for preventing the spread of the disease, is formed in two ways: the passive way (i.e., the formation of a population not susceptible to re-infection due to the natural spread of the disease) and the active way (mass immunisation). High rates of COVID-19 vaccination were achieved thanks to the development and mass production of new vaccines. The selection of the most promising vaccine platforms is one of the key aspects of successful mass immunisation. The aim of the study was to compare the characteristics of COVID-19 vaccines used for mass immunisation. The paper analyses the vaccine technology platforms, efficacy of different types of vaccines based on clinical trial results, safety of vaccines for different population groups, and potential for scaling up vaccine production in order to ensure the necessary vaccination coverage. The vaccines currently used for mass immunisation are: BNT162b2 (Pfizer/BioNTech), mRNA1273 (Moderna), Gam-COVID-Vac (N.F. Gamaleya National Research Center for Epidemiology and Microbiology), Ad26.COV2.S (Johnson & Johnson), ChAdOx1-S (AZD1222) (AstraZeneca), BBIBP-CorV (Sinopharm), CoronaVac (Sinovac Biotech), and NVX-CoV2373 (Novavax). The comparison of the main characteristics of the vaccines demonstrated that the most promising types of vaccines for COVID-19 specific prophylaxis are RNA vaccines and recombinant adenovirus vector-based vaccines.

The article presents the results of isotope-chemical research of the Tavatum thermal water deposit (coast of the Sea of Okhotsk, Magadanskaya Oblast), as well as surrounding underground and surface waters. For the first time, data on the content of isotopes of oxygen and hydrogen in the underground and surface waters were obtained, and the analysis of trace elements was performed. The results show that the chloride sodium-calcium mesohalinous thermal waters of the Tavatum deposit are atmogenic; two processes can be considered as the main processes of the chemical composition formation: 1) involvement of deep brines (including cryopeg waters) and 2) cationic exchange in the interaction of sea waters (buried during marine transgressions in the Holocene) with rocks. In the chemical composition of thermal waters, there are indicator chemical elements reflecting the impact of deep high-temperature processes. The temperature of the deep fluid estimated by different geothermometers is 117 to 128°C, and the depth of formation is at least three kilometers.
