Modern ideas about natural monopolies and their tariff regulation. Part 1. Natural monopolies
Authors: Сериков Павел Юрьевич , Гончарова Надежда Викторовна , Серикова Ирина Павловна 
Published: April 2021

Определение естественных монополий, закрепленное в российском законодательстве, недостаточно корректно, что негативно сказывается на практике их государственного регулирования в нашей стране. В этой связи авторами рассмотрено становление отечественного института естественных монополий, исследована «эволюция» понятия «естественная монополия», проанализированы подходы российских и зарубежных экономистов к регулированию деятельности естественных монополий. Отмечено, что у отечественных исследователей отсутствует консолидированный взгляд на природу и процедуру идентификации естественных монополий, в то же время имеющиеся теоретические разработки в этой области недостаточно учитываются на практике. Констатируется, что дискуссия по вопросам регулирования естественных монополий продолжается. Необходимость заполнения пробелов в законодательстве очевидна, и в первую очередь это касается обоснования собственно понятия естественных монополий и процедуры их идентификации. По мнению авторов, предпочтительным с указанной целью является обновление Федерального закона «О естественных монополиях» № 147-ФЗ - его своего рода реновация, которая позволила бы наполнить закон содержанием, соответствующим современным реалиям, в том числе актуализировать определение естественных монополий как объектов регулирования, определить адекватные времени методические подходы к их регулированию и т. д.
The definition of natural monopolies, enshrined in Russian legislation, is not correct enough, which negatively affects the practice of their state regulation in our country. In this regard, the authors considered formation of national institute of natural monopolies, investigated the “evolution” of “natural monopoly” concept, analysed the approaches of Russian and foreign economists to regulate natural monopoly activities. It is stated that the discussion on the regulation of natural monopolies continues. The need to fill the gaps in legislation is obvious, and first of all it concerns the substantiation of the actual concept of natural monopolies and the procedure for their identification. According to the authors, it is preferable for this purpose to update the Federal Law “On Natural Monopolies” No. 147-FZ - a kind of renovation that would fill the law with content that meets modern realities, including updating the definition of natural monopolies as objects of regulation, determining adequate time methodical approaches to their regulation, etc.

Published: April 2021

В настоящее время в отечественных национальных и международных стандартах отсутствуют данные по коррозионной активности атмосферы регионов, в которых расположены нефтеперекачивающие станции с резервуарными парками, эксплуатируемые российским оператором магистральных нефте- и нефтепродуктопроводов. В нормативных документах ПАО «Транснефть», регламентирующих требования к антикоррозионным покрытиям для наружной поверхности резервуаров, определены три категории коррозионной активности атмосферы по ISO 12944-2:2017. Данная классификация учитывает климатические условия регионов, но не учитывает скорость коррозии стали. В этой связи с целью определения скорости коррозии стальных конструкций в различных климатических районах, где расположены объекты организаций системы «Транснефть», была проведена серия испытаний. На 28 НПС в восьми климатических районах были установлены стенды с образцами из стали 09Г2С. Скорость коррозии металла образцов определяли гравиметрическим методом после выдержки в течение шести месяцев, одного года, двух, трех, четырех и пяти лет. Установлено, что скорость коррозии металлических образцов составила от 55 до 236 г/(м∙год), что соответствует категории коррозионной активности атмосферы С2 и С3 по ISO 12944-2:2017 и ГОСТ 34667.2-2020. Наибольшая скорость коррозии - от 177 до 236 г/(м∙год) - наблюдалась в районах расположения НПС в непосредственной близости от моря (до 1,5 км от береговой линии).
Currently, there is no data included in the state and international standards on the corrosion activity of the atmosphere in the regions in which oil pumping stations with tank farms are situated, which are operated by Russian main oil and oil products pipeline operators. In the regulatory documents of Transneft PJSC, which specify the requirement for anticorrosion coatings for the outer surfaces of tanks, three categories of atmospheric corrosion activity are defined as per ISO 12944-2:2017. This classification takes into account the climatic conditions of the regions, but not the steel corrosion rate. In this regard, in order to determine the corrosion rate of steel structure in various climatic regions, where Transneft facilities are situated, a series of tests was performed. The test bench with 09G2S steel samples was installed on 28 oil pumping stations in eight climatic regions. The corrosion rate of the metal samples was determined by the gravimetric method after tempering within the period of six months, one year, two, three, four and five years. It has been established that the corrosion rate of the metal samples amounted from 55 to 236 g/(m·per year), which corresponds to the atmospheric corrosion activity category C2 and C3 as per ISO 12944-2:2017 and GOST 34667.2-2020. The highest corrosion rate, from 177 to 236 g/(m·per year) - was observed in the OPS location regions with close proximity to sea (1,5 km to shore line).

Authors: Ubi Stanley Emmanuel 
Published: April 2021

Concrete is very variable material, having a wide range of strengths and stress-strain curve. Concrete composite material whose basic properties are related to the characteristic of constituent element, especially the aggregate. This research aimed to investigate the effect of replacing sharp sand with stone dust as an alternative to only river sand. Sieve analysis was carried out on the aggregate to determine the size of particle distribution. Slump test was carried out to compare the batches of concrete for the grade, water content between batches of concrete and amount of aggregate. Compressive strength test was carried out on concrete cubes made from sharp sand and concrete cubes made from replacement of sharp sand with stone dust also concrete made from ordinary stone dust at constant of free water/cement ratio 0.5. To check the properties of concrete produced with different materials, the tests were done for 7, 14, 21 and 28 days. The result obtained indicated that the strength of using sharp sand with stone dust in concrete production was higher than the strength of stone dust in concrete also higher than the strength of using sharp sand in concrete.
Comparison of U-spatial statistics method with Classical Statistics results in the determination of geochemical anomalies of Epithermal Gold in Khoshnameh area, Hashtjin, Iran
Authors: Seyedrahimi-Niaraq Mirmahdi 
Published: April 2021

In this study, methods based on the distribution model (with and without personal opinion) were used for the separation of anomalous zones, which include two different methods of U-spatial statistics and mean plus values of standard deviation (). The primary purpose is to compare the results of these methods with each other. To increase the accuracy of comparison, regional geochemical data were used where occurrences and mineralization zones of epithermal gold have been introduced. The study area is part of the Hashtjin geological map, which is structurally part of the folded and thrust belt and part of the Alborz Tertiary magmatic complex. Samples were taken from secondary lithogeochemical environments. Au element data concerning epithermal gold reserves were used to investigate the efficacy of these two methods. In the U- spatial statistics method, and criteria were used to determine the threshold, and in the method, the element enrichment index of the region rock units was obtained with grouping these units. The anomalous areas were identified by, and criteria. Comparison of methods was made considering the position of discovered occurrences and the occurrences obtained from these methods, the flexibility of the methods in separating the anomalous zones, and the two-dimensional spatial correlation of the three elements As, Pb, and Ag with Au element. The ability of two methods to identify potential areas is acceptable. Among these methods, it seems the method with criteria has a high degree of flexibility in separating anomalous regions in the case of epithermal type gold deposits.

Chitosan/ biphasic calcium phosphate nanofibrous scaffolds for bone tissue engineering
Authors: Truong Truong Le Bich Tram 
Published: April 2021

In this article, chitosan/biphasic calcium phosphate (CS/BCP)nanofibers were prepared by electrospinning.	From the culture of osteogenic cells, the biocompatibility of CS/BCP nanofibrous substrates was identified and increased by the photocrosslinking. The enhancement in cell attachment and proliferation was caused by the improvement in nanofibers’ mechanical properties. The biocompatibility to osteoblasts was also promoted with the content of BCP. The osteogenic differentiation in early, middle and late stage was encouraged by the addition of BCP on nanofibrous substrates. The CS/BCP nanofibers were highly specific to osteogenic cells, revealed by difficulties in the growth of non-osteogenic cells on this composite nanofibrous scaffold. The novel nanofibrous scaffolds showed great potential in the tissue engineering of bones.

Published: April 2021

The purpose of psychological protection is to maintain the integrity of the "self-concept" of the individual by protecting his consciousness from negative traumatic experiences, fear of failure, anxiety or uncertainty in their actions. The authors who studied this phenomenon in sports note that the psychological protection of the athlete - is a system of mechanisms and methods of mental self-regulation of consciousness and behavior of the individual in extreme mental conditions.
Psychological defense mechanisms are manifested in students as a regulatory system that is activated in a situation of internal or external conflict. Based on it, students often show such a defense mechanism as substitution, regression, and compensation. Considering the manifestation of protective mechanisms in boys and girls, we obtained the following indicators: reactive formations (73% in girls and 51% in boys) and projection (73% in girls and 54% in boys) (p <0.05); in boys prevails: suppression (65% in boys and 45% in girls) and intellectualization (69% in boys and 56.1% in girls) (p <0.05). We found differences in the choice of the dominant mechanism of psychological protection by swimming students. The leading mechanism in the studied contingent is substitution, and the least preferred is suppression. The study identified the manifestation of the main mechanisms of psychological protection in students who swim and analyzed certain types of protection with a description of the specific features of the system of protective mechanisms and the level of their impact depending on gender differences.

Authors: Omelchuk E.V. 
Published: April 2021

The experience of foreign scientists on the need to master knowledge of medical genetics for the professional competence of physical therapists is considered. The features of teaching the selective educational component "Medical genetics" for applicants for the second (master's) level of higher education in the field of knowledge 22 "Health" specialty 227 "Physical therapy, occupational therapy" are presented. Today, it is relevant to improve the quality of professional training of future specialists in physiotherapy, occupational therapy, in accordance with world and European standards in order to enhance the competitiveness of domestic education, optimize conditions for international student mobility and expand the capabilities of Ukrainian specialists in the domestic and international labor markets.
According to the position of modern medicine, any human pathology is often associated with heredity. Since heredity and variability are integral parts of life, medical genetics should be included in the theoretical and practical training of specialists in physiotherapy and occupational therapy. The need for genetic knowledge for specialists in physiotherapy, occupational therapy is also determined by the constant increase in the proportion of hereditary pathology in the structure of morbidity, mortality and disability of the population. We believe that physical therapists need to be prepared for new developments in healthcare, including personalized rehabilitation. The physical therapist profession must embrace medical genetics in order to fulfill its operational role and help shape the future of personalized healthcare delivery. Competence in medical genetics provides additional opportunities for working with peers to integrate such information into a healthcare perspective. By developing and demonstrating this competence, physical therapists continue to enjoy a position of respect among the general health community. We consider it important to include in the training program for applicants for the second (master's) level of higher education the area of knowledge 22 "Health", specialty 227 "Physical therapy, occupational therapy" of an educational component such as "Medical genetics". In this way, the physical therapy profession can collaborate with other medical professions to further strengthen and define its role in patient-centered health care.

The study is devoted to relevant problems of maintaining the healthy lifestyle of students of young age of Ukrainian Institute of Arts and Sciences. Calculating the kinds of reaction and level of stamina of students towards physical load according to Letunov’s test to discover the functional state of cardiovascular system.
Moving activity is a necessary part of healthy lifestyle and is determined and stipulated by totality of physical activity of a person. Both excessive and lacking physical load can be negatively marked on health state of students under the conditions of term control. Rational usage of the means of physical education has its positive influence and irrational usage can cause pathological changes in the system of blood circulation. Results of medical examination of first year students claims that the quantity of students with deflections of health state increases every year. Correct organization of the process of physical education can become driving force of all the studying process by forming and strengthening the physical education of a personality. It happens by means of stimulating the development of the most significant biological and social needs of a person such as movement, development, self- affirmation, self-education. Nowadays during practice coordination of the studying process for teachers of physical education in school and also teachers of physical education in higher educational institutions unconventional cases happen in terms of admittance of a pupil for the physical education lesson or a student for a physical education lesson, taking into account a few accidents that happened at physical education lessons at schools, which are connected to the low level of health state of majority of students. Certainly, nowadays unfavorable ecological factors, high level of stressful situations, low level of water quality, low level of food quality, poor life standards influence negatively the city residents. [1]
The implementation of modern technologies considerably fosters the decrease of physical activity, which stimulates notable rejuvenation of many diseases, that were typical for older population 10 years ago. [2,7,8]
