Published: November 2021

The adsorption capacity of two sorbents, silica SBA-15 and titanosilicate ETS-10, toward Ce(III) was tested. The obtained sorbents were characterized using X-ray diffraction, nitrogen adsorption-desorption, Scanning electron microscopy, and Fourier-transform infrared spectroscopy. The effects of solution acidity, cerium concentration, time of contact, and temperature on Ce(III) sorption were investigated. The maximum Ce(III) removal by silica SBA-15 was achieved at pH 3.0 and by titanosilicate ETS-10 at a pH range of 4.0–5.0. The Freundlich, Langmuir, and Temkin isotherm models were applied for the description of equilibrium sorption of Ce(III) by the studied absorbents. Langmuir model obeys the experimentally obtained data for both sorbents with a maximum sorption capacity of 68 and 162 mg/g for silica SBA-15 and titanosilicate ETS-10, respectively. The kinetics of the sorption were described using pseudo-first- and pseudo-second-order kinetics, Elovich, and Weber–Morris intraparticle diffusion models. The adsorption data fit accurately to pseudo-first- and pseudo-second-order kinetic models. Thermodynamic data revealed that the adsorption process was spontaneous and exothermic.

Purpose: We sought to identify the risk factors for prolonged hospitalization and delayed treatment completion after laparoscopic appendectomy in patients with uncomplicated acute appendicitis.Methods: The study retrospectively analyzed 497 patients who underwent laparoscopic appendectomies for uncomplicated appendicitis between January 2018 and December 2020. The patients were divided into an early discharge group (≤2 days) and a late discharge group (>2 days) based on the length of hospital stay (LOS). The patients were also divided into uneventful and complicated groups according to the need for additional treatment after standard follow-up.Results: Thirty-seven patients (7.4%) were included in the late discharge group. The mean LOS of the late discharge groups was 3.9 days. There were significant differences according to age, preoperative C-reactive protein (CRP), and operative time between the 2 groups. Only operative time was significantly associated with prolonged LOS in multivariate analysis. Thirty-five patients (7.0%) were included in the complicated group. The mean duration of treatment in the uneventful and complicated groups was 7.4 and 25.3 days, respectively. Significant differences existed between the uneventful and complicated groups in preoperative body temperature, preoperative CRP levels, maximal appendix diameter, and the presence of appendicoliths. In multivariate analysis, preoperative CRP levels and maximal appendix diameter were independent predictors of delayed treatment completion.Conclusion: Shorter operative time is desirable to ensure minimal hospital stay in patients with uncomplicated appendicitis. Further efforts are needed to ensure that patients with uncomplicated appendicitis do not experience delayed treatment completion after laparoscopic appendectomies.

Analyzing the Competition of HIV-1 Phenotypes with Quantum Game Theory
Authors: ÖZLÜER BAŞER Bilge
Published: November 2021

HIV-1 (Human Immunodeficiency Virus) is a virus that causes AIDS (Acquired Immunodeficiency Syndrome), which damages the immune system by reducing people's resistance to infections and diseases. Antiretroviral treatment methods are based on drug designs developed using inhibitors that suppress the dynamics that enable the maturation of the virus. However, studies are needed to improve treatment methods against infection because HIV-1 is frequently mutated and mutant viruses develop resistance to the treatment used. Therefore, it is important to model the evolutionary development of the virus. For this purpose, the developmental process and spread of HIV-1 are modeled as a game with the players of phenotypes in this study. The related searches known to be made so far have been carried out based on the rules of classical physics. However, games of survival are being played on the molecular level, where the rules of quantum mechanics work. Since the HIV-1 game is being played on the molecular level, the behaviors of the virus phenotypes are examined from the perspective of quantum computation.

Electrostatic precipitators (ESP) have been widely used in different fields such as thermal power plants, cement plants, production of constructive materials, chemical industry, fertilizer production, . . . due to their advantagesover other dust collector systems. One of the parameters which influences on dust removing efficiency of the ESP devices is the speed and velocity distribution of the polluted gas in the collecting chamber. This paper presents the research results of improving the uniform distribution of the gas velocity in the collecting chamber of ESP using CFD (Computational Fluid Dynamics) simulation. The simulation results showed that as the dispersion plate was installed at the gas inlet of the collecting chamber the velocity distribution of gas flow was more uniform and its direction was more stable towards the outlet. In addition, the dispersion plate also improved the flow stability at different flow rates and the smaller hole diameter on the dispersion plate was better for the velocity distribution and direction in the flow. The research results provide an approach foroptimum design of a ESP with high collection efficiency.

Анотація. У статті представлено дослідження авторської педагогічної системи Василя Сухомлинського, охарактеризовано форми освітньої діяльності «під блакитним небом».  Окреслено фактори удосконалення професіоналізму вчителя, які, на переконання В. Сухомлинського, розкривають творчий потенціал вчителя і визначають сенс його професіоналізму впродовж життя: наявність у нього віри в дитину; поєднання емоційної культури з тактом; дотримання вчителем інтелектуальної культури; орієнтація учнів на особистий приклад вчителя; поглиблення, поповнення, удосконалення знань; самоаналіз педагогічної праці; її дослідницький, творчий характер, використання передового педагогічного досвіду; атмосфера багатого духовного життя колективу.

Великий педагог довів, що природа сама собою не виховує, виховує лише активна взаємодія дитини з нею. Тому екологічне виховання та екологічна культура тісно пов’язані з природоохоронною діяльністю. В.Сухомлинський вважав, що самих екологічних знань з охорони навколишнього середовища, якщо вони не втілюються на практиці, недостатньо. Важливо, щоб вихованці брали участь у збереженні і збагаченні природи рідного краю, тільки у цьому разі у них формуються необхідні уміння і навички, розвивається відповідальне, бережне ставлення до навколишнього середовища.

Assessment of Healthy Eating Awareness of Schoolchildren in a Digital Environment
Authors: Solovyeva YuV , Gorelova JYu , Letuchaya TA , Mirskaya NB , Zaretskaya AR
Published: November 2021

Introduction: Daily diets of contemporary schoolchildren mainly consist of foodstuffs, which are rich in fats and carbohydrates but poor in proteins, vitamins, and trace elements. Food stereotypes associated with consumption of freeze-dried and refined food as well as fast food products have become widespread. Such negative manifestations of the eating behavior of schoolchildren are largely determined by nutritional unawareness and necessitate appropriate measures for enhancing food literacy to preserve and strengthen health of the younger generation.
Objectives: To assess nutritional awareness of contemporary schoolchildren in a digital environment using a modified questionnaire.
Materials and methods: We modified the questionnaire developed on the basis of ten principles of healthy eating promoted by the World Health Organization to establish healthy diet awareness of 73 Moscow fifth-year schoolchildren. The self-administered questionnaire contained 23 questions.
Results: Almost all the respondents lacked the necessary level of knowledge about healthy eating: 93 % and 7 % of the schoolchildren had a moderate and low food literacy level, respectively, and none of the pupils demonstrated a high level of awareness. The diet was perceived as unbalanced or partially balanced by 14 % and 7 %, respectively, and high-calorie – by 70 % of the respondents. Only 10 % of the pupils agreed that the diet influenced their school performance, while 20 % of them were not sure about that and 70 % disagreed.
Conclusions: The identified eating disorders were associated with the level of food literacy. Our questionnaire proved to be an effective tool of obtaining detailed information about dietary habits of schoolchildren, and it can therefore be recommended for a larger survey aimed at early detection of eating disorders, improvement of food literacy, and prevention of nutrition-related health problems.
Contemporary Aspects of Training in Vocational Secondary Schools
and Students’ Health
Authors: Shubochkina EI , Blinova EG
Published: November 2021

Introduction: Current vocational secondary education (VSE) in Russia is characterized by a focus on practical training (as part of dual training) aimed at improving professional competencies of graduates. It also demonstrates negative trends in adolescent health, which requires optimization and development of specific algorithms of medical support for students aged 14–22 years and older appropriate to their academic and practical workload.
Objective: To assess adaptation of college students to learning conditions, depending on their health status, and to substantiate ways of improving their health care.
Material and methods: We retrieved and analyzed information from the database of multicenter studies conducted within the unified program of the National Medical Research Center for Children’s Health of the Russian Ministry of Health. Our sample included 197 first- and second-year college boys from the cities of Omsk and Moscow studying to become welders and auto mechanics. The quality of life, health and well-being indicators were evaluated according to the International Medical Outcomes Study 36-item short-form (MOS SF-36). The students were divided into subgroups based on their health status. The statistical processing complied with modern requirements and criteria of evidence-based medicine.
Results: We established that vocational schools admitted a significant number of applicants with the above specialty preferences suffering from chronic diseases (21.1–26 %). Results of the questionnaire-based survey of future welders and car mechanics revealed difficulties in adaptation to the educational process of the students with chronic disorders expressed by lower quality of life indicators, frequent health complaints and feelings of fatigue, especially in second-year students who experience an increasing academic and practical workload.
Conclusions: Students with chronic diseases mastering professions with hazardous working conditions represent population at risk, require health monitoring, determination of professional suitability, and control over the working conditions in industrial practice. The importance of protecting health of future professionals is determined by implementation of practice-based training in 42 % of vocational schools. Models of school medicine proposed to optimize health care in comprehensive schools can be adapted to conditions of secondary vocational facilities. Foreign studies have proved feasibility of an early onset of work-related diseases in certain occupations, even before completion of training, thus necessitating vocational guidance, professional medical advice, and development of an effective system of medical support for adolescents and students.

Published: November 2021

Introduction: The key objective of national projects is to maintain and promote health of citizens. Nutrition makes a significant contribution to health protection; yet, problems related to quantitative and qualitative characteristics of nutrition, food safety, and high risks of nutrition-related diseases are obvious. Current trends necessitate the development of new approaches to training specialists majoring in preventive medicine. The students mastering a specialty program shall acquire general cultural and professional competencies and be ready to perform medical, organizational, managerial, and research activities, including those needed to respond to challenges related to safe and high-quality nutrition. The required competency building occurs when studying the main academic disciplines and may be then reinforced and deepened by the variable part (or elective academic component) of the educational program.
Objective: To substantiate the content of the variable part of the educational program on food safety aimed to improve the quality of training of public health physicians in this area.
Materials and methods: Based on the requirements of the federal higher education standard, professional standard and an exemplary educational program of higher education for students majoring in medical and preventive care, the curriculum of the Ural State Medical University was supplemented with optional academic disciplines containing separate sections on food hygiene, as well as the discipline titled “Sanitary and Epidemiological Surveillance over Food Production and Sale”.
Results and conclusions: The experience in the development and implementation of optional academic disciplines has demonstrated their high demand by students and general satisfaction with results of training. It has also created conditions for multiple repetition and consolidation of learning materials by means of food examinations in class, hygienic education according to individual and group programs, and studies of new technologies for food production, circulation, quality and safety assurance.

In this study, a large-size eutectic scintillator of Tb-doped BaCl2/NaCl/KCl was grown using the Czochralski (Cz) and halide vertical Bridgman methods (H-VB). The suitability of these two growth methods for growing the eutectic was compared. Finally, 1 inch diameter eutectic bulks were obtained using the H-VB method. The Tb3+-derived strongest intensity peak at approximately 550 nm was observed by X-ray irradiation. An approximately 3 × 3 mm transparent eutectic wafer was cut and polished from the grown eutectic bulk. An imaging test using α-ray was performed using the grown eutectic, a fiber optic plate, and an electron-multiplying CCD camera. The resolution performance for radiation-imaging applications was evaluated.

Published: November 2021

This paper presents simple techniques to significantly reduced energy consumption of DNNs: Operating at reduced voltages offers substantial energy efficiency improvement but at the expense of increasing the probability of computational errors due to hardware faults. In this context, we targeted Deep Neural Networks (DNN) as emerging energy hungry building blocks in embedded applications. Without an error feedback mechanism, blind voltage down-scaling will result in degraded accuracy or total system failure. To enable safe voltage down-scaling, in this paper two solutions based on Self-Supervised Learning (SSL) and Algorithm Based Fault Tolerance (ABFT) were developed. A DNN model trained on MNIST data-set was deployed on a Field Programmable Gate Array (FPGA) that operated at reduced voltages and employed the proposed schemes. The SSL approach provides extremely low-overhead (≈0.2%) fault detection at the cost of lower error coverage and extra training, while ABFT incurs less than 8%overheads at run-time with close to 100% error detection rate. By using the solutions, substantial energy savings, i.e., up to 40.3%,without compromising the accuracy of the model was achieved

Authors: Jiang Pengcheng
Published: November 2021

Abstract— One of the most prevalent diseases, skin cancer, has been proven to be treatable at an early stage. Thus, techniques that allow individuals to identify skin cancer symptoms early are in great demand. This paper proposed an interactive skin lesion diagnosis system based on the ensemble of multiple sophisticated CNN models for image classification. The performance of ResNet50, ResNeXt50, ResNeXt101, EfficientNetB4, Mobile-NetV2, MobileNetV3, and MnasNet are investigated separately as ensemble components. Then, using various criteria, we constructed ensembles and compared the accuracy they achieved. Moreover, we designed a method to update the ensemble for new data and examined its performance. In addition, a few natural language processing (NLP) techniques were used to make our system more user-friendly. To integrate all the functionalities, we built a user interface with PyQt5. As a result, MobileNetV3 achieved 91.02% as the best accuracy among all single models; ensemble weighted by cubic precision achieved 92.84% accuracy as the highest one in this study; a notable improvement in accuracy demonstrated the effectiveness of the model updating approach, and a system with all of the desired features was successfully developed. These findings benefit in two aspects. For model performance, applying cubic precisions can increase ensemble learning classification accuracy. For the developed diagnosis system, it can aid in the

The paper presents the results of an introduction study of four species of the genus Echinacea Moench from the collection of aromatic and medical plants of the Nikitsky Botanical Garden: E. angustifolia DС. , E. pallida (Nutt.) Nutt. , E. tennesseensis (Breadle) Small and E. purpurea (L.) Moench. Morphological and biological features of these species were identified in order to determine the prospects of their cultivation in the conditions of the Southern Coast of the Crimea. A positive interspecific dependence of the number of inflorescences (baskets) on a plant with the length of the growing season (r=0.92) was established. An intraspecific assessment of the morphometry of inflorescences, such as their diameter, the length of the lingual flowers and the height of the flower bed, showed that E. purpurea has a tendency to negatively correlate these indicators with their number on the plant. Among the studied species of the genus Echinacea, according to the complex of thirteen morpho-biological and economically valuable traits, two species differ in adaptive advantage - these are E. purpurea and E. tennesseensis , and the best samples are No. 15309 and No. 6106 with an aboveground mass yield, respectively, 1.20±0.21 kg/plant and 0.92±0.19 kg/plant. E. pallida is characterized by cumulative signs of drought resistance, it is a short growing season equal to 124±4.1 days and a narrow-lanceolate leaf blade shape (index - 9.6), which allows this species to form a significant yield of aboveground mass (0.86±0.17 kg/plant) in the arid conditions of the subtropical climate of the Southern coast of the Crimea.

The results of the study of the early stages of the ontogenesis of Aerva lanata (L.) Juss. in the conditions of introduction to the Southern coast of the Crimea are presented. Morphobiological signs of seeds, morphological features of fruits, seeds and seedlings were revealed. The fruit of A. lanata is a densely pubescent single-seeded box of a rounded shape from greenish to cream color. The morphometric parameters of the seeds have a very low level of variability (from 5 to 10%). On average, their length is 0.72 mm, width - 0.55 mm, and thickness - 0.40 mm. As a result of the research, the seeds were found to be of different quality. Immature seeds from red to dark brown are located mainly in the upper and middle part of the inflorescence. The marginal embryo is milky in color, covering the abundant perisperm in a semicircle, on average 1.55 mm in length and 0.16 mm in width. The seedlings are small lobe-shaped, petiolate light green 2 mm long and 1 mm wide. The hypocotyl is white 0.4 mm long. According to the method of distribution of diaspores, A. lanata refers to barochora plants. The coefficient of semenification was 36.2%.

Published: November 2021

The article presents data on the content and composition of the essential oil of Mentha longifolia (L.) L. plants growing in natural phytocenoses on the territory of Crimea and Abkhazia. It was found that dry raw materials in two samples from natural phytocenoses of Crimea contain 1.27 and 1.76% of essential oil per wet weight, three samples from phytocenoses of Abkhazia contain less essential oil - 0.68, 0.98 and 1.19 %. About 60 components have been identified. Two new chemotypes were identified for Crimea: carvone-piperitone (mass fraction of carvone is 66.65%, piperitone oxide - 14.37%) and piperitone-sabinene (mass fraction of piperitone oxide - 55.19% and cis-sabinene hydrate - 23.51%), and two for Abkhazia: terpene-caryophyllene (α-terpinyl acetate - 51.48%;  β-caryophyllene - 9.26%), piperitone-non-petalactone (piperitone oxide - 46.29%;  nepetalactone 4aa, 7a, 7aa - 34.85%). These Mentha longifolia chemotypes are promising for use in the food, chemical, pharmaceutical and perfume industries.
Mites from the family Phytoseiidae as an element of an anti-resistant strategy for protecting fruit plantations from spider mites
Authors: Rybareva T. S.
Published: November 2021

In the last decade, the acarocomplex of apple orchards in the plain-steppe zone of the Crimea was dominated by two species of mites, fam. Tetranychidae - Amphitetranychus viennensis (Zacher) and Panonychus ulmi (Koch). Their share in the complex of phytophagous mites was 52.5 and 32.0%, respectively. Against the background of repeated acaricidal treatments during the season, the emergence of resistant races of phytophagous mites was recorded. The proposed anti-resistant strategy for controlling the number of spider mites on an apple tree involves the use of Phytoseiulus persimilis (Athias-Henriot), Neoseiulus californicus (McGregor), and Amblyseius andersoni (Chant). The combination of methods of seasonal colonization by phytoseiids serves as the building blocks of an anti-resistant defense system.Resettlement in the spring, by flooding, of two species of acariphages, P. persimilis and A. andersoni , contributes to the formation of acarofauna, so that while the first species reduces the number of phytophagous mites (by 50-60%), the second adapts and starts feeding later, and, at the expense of daughter individuals, it allows to reduce the number of pests by the end of the second decade of June to 2-3 individuals / leaf. In summer, a double release of the predatory mite N. californicus with a norm of 30 thousand individuals / ha (150-300 individuals / every 10 trees) reduces the risk of mass reproduction of spider mites at high average daily temperatures and low humidity.

Background: “On-demand” treatments approved in the United States (US) for “OFF” episodes in Parkinson’s disease (PD) include apomorphine hydrochloride injection (SC-APO), apomorphine sublingual film (APL), and levodopa inhalation powder (CVT-301). APL received US approval in 2020, and its cost-effectiveness has not been compared with SC-APO and CVT-301.

Objective: To develop a cost-effectiveness analysis model comparing APL versus SC-APO and CVT-301 for treatment of patients with PD experiencing “OFF” episodes from a US payer perspective.

Methods: The model estimated total costs and effectiveness for each comparator arm, informed from the treatments’ pivotal studies or literature, over a 10-year horizon. Total and incremental patient costs (in 2020 US dollars), total time spent without “OFF” episode symptoms, and quality-adjusted life years (QALY) gained were summarized and compared. Incremental cost-effectiveness ratios for APL versus SC-APO and CVT-301 were estimated and expressed as incremental patient costs per patient QALY gained and incremental cost per “OFF” hour avoided. Scenario analyses varying inputs and including caregiver costs were also conducted.

Results: In the base case, APL had the lowest total “on-demand” treatment costs ($42,095) compared with SC-APO ($276,320; difference: –$234,225) and CVT-301 ($69,577; difference: –$27,482) over the 10-year horizon. APL was also associated with the highest utility, with incremental QALYs of 0.019 versus SC-APO and 0.235 versus CVT-301. APL was dominant over CVT-301 in terms of incremental cost per “OFF” hour, and dominant over both CVT-301 and SC-APO in terms of incremental cost per QALY gained. In all scenario analyses, APL was dominant against both SC-APO and CVT-301, confirming the robustness of the base-case results.

Discussion: APL was dominant compared with both comparator arms, being less costly and more effective on average than SC-APO and CVT-301 in terms of QALYs. For SC-APO, cost-effectiveness of APL was driven by lower “on-demand” treatment costs and adverse event–related disutilities. For CVT-301, cost-effectiveness of APL was driven by lower “on-demand” treatment costs and substantially higher efficacy.

Conclusions: From a US payer perspective, APL represents a cost-effective option compared with SC-APO and CVT-301 for treatment of “OFF” episodes in patients with PD.
