Published: December 2021

The production of enzyme preparations occupies one of the leading places in modern biotechnology and belongs to industries whose production volume is constantly growing, and the scope of application is expanding. Therefore, it is advisable to use enzymes for various industrial processes from an economic and technological standpoint. The main purpose of the study is to examine the chemical composition and activity of the enzyme preparation papain with subsequent use in the technology of meat products production to increase the biological value and improve the functional and technological properties of the finished product. The following research methods were used to solve these problems: moisture content – by drying the sample to a constant mass; fat content – by the Soxhlet method; ash content – by the generally accepted weight method; protein content – by the Kjeldahl method; papain activity was determined by a method based on the spectrophotometric determination of the number of proteolysis products under the action of an enzyme. Based on the results of the analysis of literature sources and own studies, the prospects of the research and use of enzymes and enzyme preparations obtained on their basis in the food industry are demonstrated, since this contributes to improving the quality of finished products and the level of greening of production, more rational use of raw materials and material resources. As a result of a study of the chemical composition, it was determined that the enzyme papain has a high protein content of 87.44%, so it has a broader effect on meat proteins. During the studies, the dependence of papain activity on the pH of the medium, temperature, sodium chloride and enzyme concentrations was investigated. The results of the conducted studies demonstrated that papain shows the greatest activity in the pH range of 5.5-6.0. The enzyme has a maximum collagenase activity of PH 6.0 and at a temperature of 50-60°C. The obtained results allow expanding the range of meat products, increasing the nutritional and biological value of raw materials, and obtaining a finished product with high organoleptic parameters
Development of a propolis collecting device
Authors: Dvykaliuk Roman , Adamchuk Leonora
Published: December 2021

Propolis is a sticky resinous substance collected from buds, leaves, stems of wild plants and processed by bees, which has bactericidal properties and which they use to seal cracks in the hive, polish the walls of wax cells, embalm the corpses of enemies. The analysis of research and publications gives grounds to conclude that Ukraine has not yet paid sufficient attention to the conditions of propolis production. No devices or equipment to improve the process of production of safe and highquality propolis, which will meet the high requirements of regulatory acts on the quality and safety of food products and raw materials, are available today. Currently, apiaries use methods of collecting propolis, which require considerable human labor, are not economically efficient, and the resulting product does not meet the quality requirements of market operators. Therefore, there is a need to improve existing technologies for obtaining propolis, to ameliorate sanitary-hygienic conditions of production, to increase productivity and economic efficiency, mechanization, and automation of the production process. The goal of the present work was to develop a new propolis collecting device. The study was carried out as a part of the thesis research at the Department of Standardization and Certification of Agricultural Products of the National University of Life and Environmental Sciences of Ukraine during 2020-2021. A new propolis collecting device has been designed and manufactured. The design of the device shafts and the principle of mechanical cleaning of the grids from the propolis, laid down during its development, can be used to develop highly automated lines for cleaning the grids. The use of the device in industrial apiaries in countries with tropical and subtropical climates is possible by placing the device in honeycomb storage, if available, or in a manufacturing area equipped with air conditioning. For a good cleaning of the grids with propolis using the device, it is sufficient to cool the grids at a temperature of +5°C for 60-90 minutes, depending on the type of propolis. The device can be used at apiaries in Ukraine and in other countries where the production of propolis from bee colonies is carried out using elastic grids. The use of the device ensures the production of pure propolis without mechanical impurities, which meets the requirements of current legislation. The developed device is patented, a patent No. 139736 “Propolis collecting device”

Authors:   National University of Life and Environmental Sciences of Ukraine, Chuienko R.
Published: December 2021

An asynchronous electric motor with a short-circuited rotor is the most common means of converting electrical energy into mechanical energy in the electric drive of working machines in industry and agriculture. Modern methods of increasing the energy efficiency of induction motors with short-circuited rotor are aimed at finding with the help of computer technology the optimal solutions in the processes of their design, production and operation using new high-performance materials in machines. Such methods do not change the physical processes occurring in the induction motor, ie are passive. However, despite numerous improvements and scientific achievements, technical and economic indicators of induction motors still do not meet modern energy requirements. It is necessary to use ways to increase the energy efficiency of induction motors while maintaining their simplicity and reliability. It is proposed to use internal capacitive compensation of reactive power of induction motors. The aim of the research is to develop a mathematical model of an induction motor with internal capacitive reactive power compensation in the MathLab Simulink software environment for the calculation of operating and mechanical characteristics. A mathematical model of an induction motor with internal capacitive reactive power compensation in the MathLab Simulink software environment using the theory of electric circuits has been developed. The developed mathematical model allows to study the working and mechanical characteristics of an induction motor with internal capacitive compensation of reactive power. Numerical researches of characteristics of the induction motor with internal capacitive compensation of reactive power are carried out and their comparison with corresponding characteristics of the basic induction motor is carried out.

Published: December 2021

The issue of legal regulation of information support on soils is considered. The characteristics of large-scale soil studies in Ukraine, which were conducted during 1957–1961, are given. The reasons for the inconsistency of the available information on the structure and condition of the soil cover are established. It is substantiated that the data of environmental impact assessments of ecological monitoring, soil survey, cadastral documentation, etc. can be sources of ecological information. Based on the legal analysis, it was concluded that the draft law of Ukraine «On Soil Conservation and Protection of Fertility» should establish that documented information on soil condition and ongoing soil protection measures should be open, publicly available, as it is public interest, except for information that is included in the category of information with limited access. Keywords: land, soil, soil cover, land use, soil protection, soil information, soil survey, monitoring, cadastral documentation

Published: December 2021

Objective: To analyze the clinical records of patients with gastric adenocarcinoma, treated at two different public health institutions in Mexico to determine survival rates. Methods: Cox proportional-hazards model was fitted to identify the factors involved in survival of patients. Result: The results show that subjects aged 41 to 50 years of age had a 56% lower risk of death from gastric cancer compared to those <40 years of age. Asthenia and/or adynamia, weight loss and leukocytosis increased the risk of dying. The incidence of melena was found to be a protective factor for mortality. Conclusion: At age <40 years, symptoms such as asthenia, adynamia and weight loss and leukocytosis are poor prognosis predictors in patients with gastric cancer. Melena seems to be a protective sign of gastric cancer mortality in Mexico. Given the low 5-year survival rate in patients with gastric cancer, further studies are necessary to explore the factors associated with survival to contribute to effective intervention.

The research aims to examine the democratic ideals ofparticipatory, inclusive democracy with "strong public" andclear means of interest articulation, in contrast to transitional, "delegativedemocracy," with local and national dynasties and the marginalized public.Employing the concept given by John Dewy, Jurgen Habermas, NancyFraser, Samuel P. Huntington, Takis Fotopoulos, the study is analytical andevaluative in nature, measuring the gap between theory and practice. Theprime area of concern is Pakistan, and the study is meant to answer "why"questions about the pendulum movement from authoritarian military ruleand democratic dispensations; and the inability of the delegatedtransitional democracy of Pakistan to transform into a consolidateddemocratic system. The supposition of the study is that though democraticnorms and awareness of people's interests are present even in the far-offperipheral regions of Pakistan yet in the presence of strong local dynastieswith local hegemonic designs, Pakistan remains a transitional democracy.

Authors: Войтік Андрій , Кравченко Василь , Пушка Олександр , Щур Тарас
Published: December 2021

Рекуперація використаної енергії є одним із напрямів розвитку енергозбереження під час використання машин. Під час роботи сільськогосподарських машин одним із резервів рекуперації енергії є виконання посівних робіт машинами, робочі органи яких розміщені на рухомих секціях, що копіюють поверхню поля. Оскільки поля зазвичай не є ідеально рівними, тому існує велика ймовірність примусового руху секцій відносно рам машин. Cтворену таким рухом енергію і можна розглядати як енергію для рекуперації.

Основними схемами кріплення висівних секцій сівалок є паралелограмна та радіальна. Виконавчим механізмом системи рекуперації руху секцій сівалок буде гідроциліндр, рух поршня якого створюватиме потік робочої рідини. У паралелограмній підвісці розмістимо гідроциліндр по лінії більшої діагоналі паралелограма. У радіальній підвісці сошникової секції хід штока гідроциліндра буде залежати від зміни вертикального положення сошника, а також від конструктивних особливостей секції.

Результати розрахунків показують, що за однакових зовнішніх умов, а саме нерівностей поля, і за фактичних розмірів паралелограмної та радіальної підвісок робочих органів вибраних сівалок зміна довжини проєктованого штока гідроциліндра радіальної підвіски менш виражена, ніж паралелограмної підвіски. Також проведені теоретичні дослідження з визначення можливих переміщень штока, вмонтованого в багатошарнірні секції посівних машин, показали, що за використання гідроциліндра з діаметром поршня 40 мм вони дозволяють створювати подачу робочої рідини до 8,1 л/хв для паралелограмних секцій сівалки та до 3,9 л/хв для радіальних підвісок секцій.

On the convergence of bumping routes to their limit shapes in the RSK algorithm: numerical experiments
Authors: Vassiliev Nikolay , Duzhin Vasilii , Kuzmin Artem
Published: December 2021

Introduction: The Robinson — Schensted — Knuth (RSK) algorithm transforms a sequence of elements of a linearly ordered set into a pair of Young tableaux P, Q of the same shape. This transformation is based on the process of bumping and inserting elements in tableau P according to special rules. The trajectory formed by all the boxes of the tableau P shifted in the RSK algorithm is called the bumping route. D. Romik and P. Śniady in 2016 obtained an explicit formula for the limit shape of the bumping route, which is determined by its first element. However, the rate of convergence of the bumping routes to the limit shape has not been previously investigated either theoretically or by numerical experiments. Purpose: Carrying out computer experiments to study the dynamics of the bumping routes produced by the RSK algorithm on Young tableaux as their sizes increase. Calculation of statistical means and variances of deviations of bumping routes from their limit shapes in the L2 metric for various values fed to the input of the RSK algorithm. Results: A series of computer experiments have been carried out on Young tableaux, consisting of up to 10 million boxes. We used 300 tableaux of each size. Different input values (0.1, 0.3, 0.5, 0.7, 0.9) were added to each such tableau using the RSK algorithm, and the deviations of the bumping routes built from these values from the corresponding limit shapes were calculated. The graphs of the statistical mean values and variances of these deviations were produced. It is noticed that the deviations decrease in proportion to the fourth root of the tableau size n. An approximation of the dependence of the mean values of deviations on n was obtained using the least squares method.

Published: December 2021

Introduction: The problem of remote monitoring of people's health has become especially urgent nowadays due to the rapid spread of dangerous infectious and viral diseases, such as COVID-19. This period was especially difficult for pregnant women. According to Rosstat statistics, in 2020, maternal mortality in Russia increased by 24.4% compared to 2019 and reached 11.2 per 100,000 newborns. This is the worst level since 2013. In the current conditions, there is a necessity for developing remote monitoring systems which allow you to check the health status of a pregnant woman remotely using tools outside a medical institution. Purpose: To develop the structure and validate the choice of elements for a hardware and software complex which would perform remote monitoring outside a medical institution and assess the condition of pregnant women during their active life. Results: An automated questionnaire for pregnant women has been developed in accordance with the methodological recommendations of the Ministry of Health of the Russian Federation, providing a quantitative assessment of the current state of a pregnant woman in order to study the dynamics of her health. Based on the results of instrumental studies, according to 30 factors of patient's body functioning and the questionnaire data, a set of diagnostically significant indicators was developed. For each of them, a range of values was specified (norm, alarm, pathology). We have developed an experimental sample of the hardware and software complex and tested its functioning, particularly the modes of taking biomedical data by urine tests. The algorithms for processing and analysis of biomedical data have been experimentally studied in order to confirm the validity of the proposed solutions. Practical relevance: The results of the studies allow us to affirmatively answer the question about the possibility of remote monitoring outside a medical institution and assessing the health state of a pregnant woman in order to predict pregnancy complications, as well as to validate the choice of measuring channels for recording a complex of biomedical signals and data, and the choice of algorithms for information processing and analysis.
Analysis of the probability of connectivity of a telecommunications network based on the reduction of several non-connectivity events to a union of independent events
Authors: Batenkov Aleksandr , Batenkov Kirill , Fokin Aleksandr
Published: December 2021

Introduction: For large and structurally complex telecommunication networks, calculating the connectivity probability turns out to be a very cumbersome and time-consuming process due to the huge number of elements in the resulting expression. The most expedient way out of this situation is a method based on the representation of a network connectivity event in the form of sums of products of incompatible events. However, this method also requires performing additional operations on sets in some cases. Purpose: To eliminate the main disadvantages of the method using multi-variable inversion. Results: It is shown that the connectivity event of a graph should be interpreted as a union of connectivity events of all its subgraphs, which leads to the validity of the expression for the connectivity event of the network in the form of a union of connectivity events of typical subgraphs (path, backbone, and in general, a multi-pole tree) of the original random graph. An iterative procedure is proposed for bringing a given number of connectivity events to the union of independent events by sequentially adding subgraph disjoint events. The possibility of eliminating repetitive routine procedures inherent in methods using multi-variable inversion is proved by considering not the union of connectivity events (incoherence) degenerating into the sum of incompatible products, but the intersection of opposite events, which also leads to a similar sum. However, to obtain this sum, there is no need to perform a multi-variable inversion for each of the terms over all those previously analyzed. Practical relevance: The obtained analytical relations can be applied in the analysis of reliability, survivability or stability of complex telecommunications networks.

Authors: Smirnova Ludmila , Ponomarenko Gennadiy , Suslyaev Vadim
Published: December 2021

Introduction: One of the methods for managing the quality of prosthetics is optimizing the composition of a modular prosthesis components. Mistakes in choosing models for functional modules of a prosthesis lead to a limited realization of the patient's potential capabilities, or to the choice of expensive highly functional models whose potential cannot be fully realized with the given body system disabilities. One of the most effective ways to solve this problem is to use the computer technology capabilities. Purpose: Substantiation of the methodology for the development of an innovative computer technology for personalized synthesis of a lower-limb prosthesis, including the development of the structure of an information-measuring system for its implementation. Methods: Analysis, synthesis, analogy; expert survey; analytic hierarchy process (Saaty method). The conceptual language of the International Classification of Functioning, Disability and Health was used to describe the factors influencing the requirements for the characteristics of prosthetic modules. Results: In order to choose models for prosthetic modules, we should use an extended system of factors, including both the basic factors associated with the purpose of the products and indicated in the catalogs, and additional factors: impairment indicators of the body functions and structures, the capacity and performance of the patient's activity and participation, the presence of barriers and facilitators environmental factors in which the prosthesis is planned to be used. Taking this system of factors into account, a structural diagram of an information-measuring system for examining a prosthetic patient has been developed. To select the components for the prosthesis, we have substantiated the necessity of creating a global electronic catalog, combining structured information on the models of prosthetic modules supplied by various manufacturers. A matrix representation form is proposed for the knowledge base, reflecting the rules for choosing models according to the correspondence of their characteristics to the estimates of the factors. The methodology of computerized selection of models from the electronic catalog has been substantiated. Practical relevance: The results of the work are a step towards the creation of a technology for a computerized multicriteria choice of components for a modular prosthesis, taking into account the personal needs and functional capabilities of the patient. The use of this technology will improve the patient's rehabilitation level and the quality of his or her life.

Salah satu masalah sosial saat ini adalah masalah pergaulan bebas dan bijak bermedsos yang terjadi pada kalangan remaja. Ada dua dampak yang ditimbulkan dari perilaku pergaulan bebas dan bijak bermedos di kalangan remaja yaitu kenakalan remaja dan penggunaan media sosial. Seperti kita ketahui bahwa banyak dampak buruk dari kenakalan remaja dan cenderung bersifat negatif seperti halnya, pergaulan bebas yang menimbulkan seks bebas dapat berakibat fatal bagi kesehatan. Seks bebas dapat terjadi karena pengaruh dari lingkungan dan salah pilihnya seseorang terhadap lingkungan tempatnya bergaul. Selain itu juga penggunaan media sosial yang harus kita lakukan adalah bagaiamana cara menggunakan media sosaial secara bijak. Tujuan kegiatan pengabdian masyarakat adalah meningkatkan pengetahuan dengan memberikan penyuluhan tentang bahaya pergaulan bebas dan bijak media sosial di kalangan remaja, dan diharapkan terjadinya perubahan pengetahuan dan perilaku terhadap bahaya pergaulan bebas dan bijak media sosial di kalangan remaja. Kegiatan ini dilaksanakan dua kali yaitu pertama dengan memberikan penyuluhan tentang bahaya pergaulan bebas di kalangan remaja, kedua dengan cara bijak menggunakan media sosial dalam kehiduan sehari-hari, agar terbentengi hal-hal yang negatif. Hasil dari pengabdian ini menunjukkan bahwa ada peningkatan pengetahuan dan respon yang positif bagi para remaja.

Ketapang and Kayong Utara Regency have road construction that often suffers damage before the planned life age caused by the behavior of expansive clay. The subgrade is a fundamental structure in building road construction because the subgrade will support traffic loads or construction loads. The strength and durability of the pavement structure road will depend on the properties and bearing capacity of the subgrade. Practically soil stabilization is a reinforcement engineering against foundation or subgrade by using mixed materials. Therefore, different soil improvement variations are needed. Based on the test result, the CBR value of Sukadana initially gets a 2.95% point. The CBR value for the 6% and 10 % mixture, respectively, gets 17.14% and 25.02%. The CBR value of Sungai Melayu Rayak originally get 4.65% point. Then, for the 6% and 10% mixture, the CBR values increased by 13.78% and 18%. The value of the bearing capacity of the highway soil construction can be know from the results of CBR testing on each variation. The CBR also can measure the strength of the soil. The addition of cement to the earth tends to increase the bearing capacity of the ground. It is because cement can function as a binder between soil particles with chemical compounds contained in cement.

Background: Curcumin (Cur) is a natural yellow polyphenol extracted from the turmeric rhizome (Curcuma longa). Cur is known for its potential therapeutic properties as an analgesic, anti-inflammatory, antioxidant, antimicrobial, hepatoprotective, and anti-mutagenic, although some of these biological activities remain unproven. Epidemiological studies have shown a positive relationship between high-fat diets and diet-related chronic diseases. We hypothesized that some adverse effects of consuming atherogenic or high-fat diets (AD) can be ameliorated by Cur supplementation. Using an experimental model of rats, this study investigated the significance of Cur when it is given as a supplement in an AD.Methods: Healthy adult Wistar rats were randomly assigned to one of three groups. Controls (C) received a standard diet and experimental rats were fed with AD or AD+Cur for 5 weeks. Cur (100 mg/kg body weight) was given orally daily, plus piperine (5 mg/kg body weight). The effect of Cur supplementation was studied on zoometrics, visceral fat content, serum lipids profile, hepatosteatosis, liver function and oxidative status. Results: Diets did not alter energy consumption. As compared to the other groups, AD+Cur group showed a lower total visceral fat content, percentage of perirenal, mesenteric, and pelvic fat, and body weight gain (P< 0.05). Serum total cholesterol (P<0.0001), non-HDL-C (P<0.0001) levels were significantly higher in AD groups as compared with C. Serum triglycerides and HDL-C levels remained similar among groups (P>0.05). AD induced a liver injury with macrovesicular steatosis and portal inflammation. AD+Cur rats presented microvesicular steatosis with no inflammation, achieving the lowest level of alanine aminotransferase (ALT; P<0.0001) and reductions of aspartate aminotransferase (AST; P<0.0001). Liver homogenates from AD+Cur showed that Cur supplementation reduced the dichlorofluorescein diacetate (DCFH-DA) oxidation rate induced by AD by 25 % and deferoxamine and superoxide dismutase inhibited DCFH-DA. Conclusion: Cur as a dietary supplement showed a protective effect against obesity and inflammation, but its cardioprotective ability remained unproved. Cur may develop as a promising therapeutic agent for liver diseases induced by oxidative stress. This study provides supporting evidence to confirm the beneficial effects of curcumin from the point of view of functional food science.  Keywords: curcumin, liver injury, ROS, atherogenic diet, visceral fat, obesity

Authors: Gasich E. L. , Orina* A. S.
Published: December 2021

Fungal strain MF KP-12.1, which is similar in morphological and cultural characteristics to Botryosphaeria fungi, was isolated from the seeds of white lupine variety Dega grown in Oryol region in 2018. Phylogenetic analysis of the large rRNA subunit (LSU), elongation factor-1α (TEF) and internal transcribed spacer (ITS) fragments was used to accurately identify the isolated strain as B. sinensis. When 2-week-old white lupine plants were treated under laboratory conditions with mycelial suspension of B. sinensis MF KP-12.1, plant damage reached 67 % on day 3, and 100 % plant death was observed on day 10. Pathogenicity of B. sinensis MF KP-12.1 was confirmed by re-isolation of the strain from damaged plant tissue. This is the first detection of B. sinensis on white lupine, which has not been previously reported as a host for this fungus. It is also the first detection of B. sinensis in Russia.

BACKGROUND: A framework to establish the biopsychosocial patient profile for persons with low back pain has been recently proposed and validated: The Pain and Disability Drivers Management model (PDDM). In order to facilitate its clinical integration, we developed the PDDM rating scale. OBJECTIVES: To determine the inter-rater agreement of the PDDM rating scale. A second objective was to determine if this inter-rater agreement varies according to the complexity of patients’ clinical presentation. METHODS: We recruited physiotherapists during one-day workshops on the PDDM. We asked each participant to assess two clinical vignettes using the rating scale. One vignette presented a typical clinical presentation (moderate level of difficulty) and one presented an atypical presentation (complex level of difficulty). We determined inter-rater agreement with the proportion of participants who gave the same answer for each PDDM domain. RESULTS: For the typical vignette, the inter-rater agreement per domain was moderate to good (between 0.54 and 0.97). For the complex vignette, the inter-rater agreement per domain was poor to good (between 0.49 and 0.81). The comparison between the two vignettes showed a significant difference (p< 0.01) for nociceptive and cognitive-emotional domains. CONCLUSION: Overall performance indicates that the rating scale present adequate agreement for clinical use, but specific domains require further development.

Published: December 2021

BACKGROUND: Therapeutic exercise (TE) is recommended in multimodal treatment for patients with non-specific chronic back pain (cLBP). OBJECTIVE: The aim of this study is to identify an exercise or a spectrum of exercises, well described and reproducible by the clinician, for cLBP patients. METHODS: Systematic review by researching in the databases MEDLINE, EMBASE, PEDro, CINAHL, and Scopus. Evidence from Randomized Controlled Trials (RCTs) supported the TE in patients with non-specific cLBP, provided that it was well described and could be repeated by another therapist. Methodological evaluation was performed using the PEDro scale and only studies with a score of ⩾ 6 were included. The assessment of the intervention description was carried out with the TIDieR checklist. The risk of bias was examined. RESULTS: Twenty-one articles were included in this systematic review. The defective description and the poorly reporting of the intervention makes it more difficult for the clinician to include the TE into clinical practice. CONCLUSIONS: The findings of this study showed that the reporting of the intervention in high quality RCT on chronic low back pain is low, threatening the external validity of the results.

Drug resistance is a critical factor responsible for the recurrence of non-small cell lung cancer (NSCLC). Previous studies suggest that curcumin acts as a chemosensitizer and radiosensitizer in human malignancies, but the underlying mechanism remains elusive. In the present study, we explored how curcumin regulates the expression of miR-142-5p and sensitizes NSCLC cells to crizotinib. We found that miR-142-5p is significantly downregulated in NSCLC tissue samples and cell lines. Curcumin could increase crizotinib cytotoxicity by epigenetically restoring the expression of miR-142-5p. Furthermore, curcumin treatment suppressed the expression of DNA methylation-related enzymes, including DNMT1, DNMT3A, and DNMT3B, in NSCLC cells. In addition, the upregulation of miR-142-5p expression increased crizotinib cytotoxicity and induced apoptosis in tumor cells in a similar manner to that of curcumin. Strikingly, miR-142-5p overexpression suppressed crizotinib-induced autophagy in A549 and H460 cells. Mechanistically, miR-142-5p inhibited autophagy in lung cancer cells by targeting Ulk1. Overexpression of Ulk1 abrogated the miR-142-5p-induced elevation of crizotinib cytotoxicity in A549 and H460 cells. Collectively, our findings demonstrate that curcumin sensitizes NSCLC cells to crizotinib by inactivating autophagy through the regulation of miR-142-5p and its target Ulk1.
