Authors: Grytsyuk I.V. , Ivanov E.A. , Kovalchuk I.P
Published: August 2020

The ponds distribution regularities within the basin, landscape and landscape-hydrological systems in the Volyn region have been established. The geospatial pond farms conditions and functioning analysis of region made it possible to evaluate advantages and disadvantages to use appropriate types of systems for these needs. To estimate basin systems saturation level by ponds was processed topographic maps of 1 : 50,000 scale. 586 ponds with an area of water mirror over 0.5 ha were identified on them. The average area of reservoirs is 6.4‒67.5 ha. Construction and exploitation of ponds in river basins of Volyn region significantly changes their landscape structure, influences on functioning of water bodies. The peculiarity of region is considerable river regulation on its upper parts. Maximum transformations (including hydrotechnical ones) have undergone floodplain complexes of small rivers, first of all on rivers Lypa, Luga, Serny and Chornoguzka.
In the Pripyat basin, counting about 456 pond’s with a total water mirror area of 3 400,61 ha. Most ponds are concentrated in Goryn, Styr, Stokhid and Turiya basin systems. In Western Bug basin there are 131 ponds with a total area of 841.78 ha. The basin is characterized by higher rates of pond density (over 40 units/1000 km2).
Most of ponds are locating in Luga river basin (110 units). For individual landscape places, quantitative parameters of pond differ, and the pond density varies from 7,69 to 86,48 units/1000 km2. The highest pond density is characteristic for Volyn highland. It is declining substantially in northeast direction, especially within Polissya alluvial-lakes, floodplains and terraces places of region.
It is proposed to use landscape-hydrological systems as an alternative to inventory of water bodies. The highest counts of ponds in region are in Styr-III sub-basins (175 units; 29.9 % of their total) and Luga-III (109 units). Density of ponds in these sub-basins exceeds 50‒80 units/1000 km2. The high density of ponds is characteristic of Goryn-III sub-basin, especially of territory stocking index (13.52 km2/1000 km2). In recent years, there has been a tendency to increase of pond farms number in region.
MODERN TRANSFORMATION OF SEASONAL RUNOFF DISTRIBUTION OF THE SIVERSKYI DONETS RIVER BASIN
Authors: Bolbot H.V. , Grebin V. V.
Published: August 2020

The annual runoff distribution of the Siverskyi Donets River Basin in the period of modern climate change was estimated. The annual runoff distribution of the Siverskyi Donets Basin was researched for two characteristic periods (from the beginning of observations to 1988 and from 1989 to 2018). The assessment was performed for three water year types: wet year, average year and dry year. The research was performed for three groups of rivers depending on their affiliation to a particular part of the Basin. During the research, the average monthly runoff of the hydrological gauges, which we selected for the study were averaged. The annual runoff distribution was leveled in the current period. The Siverskyi Donets Basin is characterized by the peculiar physico-geographical conditions, so the annual runoff distribution is somewhat different for different part of the Basin. Differences in the annual runoff distribution of the right-bank tributaries, the left-bank tributaries and the Siverskyi Donets River were revealed. For the left-bank tributaries, which are less affected by anthropogenic load, climate change has led to a significant increase in runoff of the winter and summer-autumn low period. For the right-bank tributaries of the Siverskyi Donets, flowing within the industrial part of Donbas, the share of low period runoff has not changed, or even decreased. This is due to the reduction of mine drainage, due to the reduction of industrial production in the region. Instead, the share of autumn-winter period in the annual runoff has increased for the right-bank tributaries and the Siverskyi Donets River itself.
It is established that the share of spring floods from the annual volume of runoff has significantly decreased and the share of the summer-autumn period for the rivers of the Siverskyi Donets Basin in the modern period has increased. The winter runoff of the left-bank tributaries of the modern period is characterized by an increase. The right-bank tributaries of the Basin are characterized by a decrease in winter runoff. Currently, in dry years, spring flood is practically not allocated on the annual hydrograph; the share of runoff in the limited months has significantly increased. At the present stage of climate change, the annual runoff distribution of the Siverskyi Donets River Basin has undergone significant changes.

Published: August 2020

The Dniester River is the second longest and most watery river in Ukraine, which is characterized by heterogeneity and diversity of conditions for the formation of water flow, both in terms of its length and numerous tributaries. The right-bank and left-bank parts of the Dniester River basin are quite different in terms of physical and geographical conditions, drainage network density, water regime and river water content. The object of the study is the average annual water flow of the rivers of the Dniester River basin, the subject is its calculated characteristics of different probabilities of exceeding. The purpose of the study is to analyze, systematize, generalize and compare the calculated characteristics of the average annual water flow of rivers of the right-bank and left-bank parts of the Dniester basin.
Input data is based on the average annual river water discharge from 50 stream flow measuring stations in the Dniester River basin (to Zalishchyky). The data bank was formed from the beginning of observations until 2016. 89% of 28 right-bank stream flow measuring stations have a continuous series of more than 50 years, and 86% of 22 left-bank stream flow measuring stations have a continuous series of observations of more than 50 years. As for the catchment areas of rivers in the closing areas, the right bank is dominated by small ones – 64% of 28 stations have an area of less than 500 km2 and 25% – from 500 to 1,000 km2. 37% of 22 stations on the left bank have a catchment area of less than 500 km2 and 41% – from 500 to 1,000 km2. According to statistical criteria, the series of observations of the average annual river water discharge in both parts were mainly homogeneous and representative.
Analytical distribution curves were calculated by the method of moments, as the coefficients of variation do not exceed 0.50. Generalization and comparison of the calculated characteristics of the average annual water flow of different probabilities of exceeding the rivers of the right-bank and left-bank parts of the Dniester basin have shown that the smallest scatter of certain analytical ordinates is observed for the probability of exceeding 50%, the transition coefficients from the norm are close to 1. The greatest spread of variation of ordinates is observed at extreme probabilities of excess of distributions, that is 0,01 % and 99 %. Analysis of the ranges of variability of transition coefficients from the norm of average annual water consumption has shown that the intensity of their change in the region of rare probabilities (0.01, 0.1, 1 %%) on the left bank is more significant than on the right bank of the Dniester basin. As for low-water supplies (95, 97, 99 %%), their ranges of variability coincide in both studied parts.
SPATIAL DISTRIBUTION OF MINIMUM RIVER RUNOFF IN THE PRUT AND SIRET BASINS (WITHIN UKRAINE)
Authors: Surai K.S. , Obodovskyi O.G , Pochaevets O.O.
Published: August 2020

This article gives an estimation of minimum river water flow of the Prut River and the Siret River basins. There are two special periods of low flow between floods. The first one runs from August to November (summer-autumn period) and the second one runs from December to February (winter period). These periods were separated because of different genetics of runoff formation. It was found that 7 days is an optimal period with a stable minimum water flow. Physical and geographical features of the river basin, comparative flow and precipitation graph, scientific works of American scientists became the confirmation for giving preference to 7-days period. All series of observations are homogeneous according to the calculations in the program StokStat. In general, all samples are homogeneous for at least one criterion with 1% level of significance and can be used for further research. The samples of the average 7-day minimum water runoff from the beginning of observations until 2018 became the basis for the construction of maps of the distribution of the minimum water runoff across the study area. The result of this work represents two current maps of the distribution of runoff modules (l*s / km2) of the summer-autumn and winter low water periods. There was conducted the research of the connection between the actual values and the values taken from the maps. The connection between calculated and cartographed minimum modules of water flow showed a close correlation, the approximation coefficients are R2 = 0.9731 and 0.986 for two maps. In this case, the connection line is at an angle close to 45°. We can see a decrease of minimum water flow modules in the direction from west to northeast and a parallel decrease in the density of the distribution of isolines. The altitude has a similar distribution in this area, so there was evaluated a correlation between these two parameters. It is close, the approximation coefficients are R2= 0.5618 and 0.6661 for winter and summer-autumn periods. Consequently, the constructed maps are reliable and can be used in the future to determine the value of minimum flow modules from other parts of the basins for practical and scientific purposes. In particular, this concerns the estimation of the minimum runoff of the river basins, for solving various water management tasks: planning water supply and water intake works, designing and constructing hydrotechnical structures, performing reclamation works, drought assessment.
Courts’ Participation in Lawmaking: Critical Analysis of the Theory and Practice of Legislative Initiative
Authors: Zbaratskiy B. A.
Published: August 2020

The paper explores the implementation of the power to initiate legislation by the highest judicial bodies of Russia—the Supreme Court of the Russian Federation and the Constitutional Court of the Russian Federation. The author focuses on specific legislative initiatives of the higher judiciary and provides examples of judicial intrusion into the field of activities of other branches of power. The author highlights the need for additional doctrinal elaboration of draft laws initiated on behalf of the Supreme Court of the Russian Federation. The paper analyzes the reasons for the non-application of the power to initiate legislation by the Constitutional Court of the Russian Federation, in particular: involvement in political life, the principle “nobody can be a judge in their own case,” authority impairment, judges’ opinion, the use of legal standings, complexity of the mechanisms. The author argues that the RF Constitutional Court participation in political activities is mediated. The conclusion is made about the necessity of using the structural-system method of scientific cognition in the study of the reasons for non-application of the institute of legislative initiative. The author substantiates the necessity for the Constitutional Court of the Russian Federation to apply the power to initiate legislation in exceptional cases, in cases of impossibility of using other forms of participation in law-making.

Implementation of the Constitutional Obligation of the State to Ensure Access to Justice in the Context of Digital Technologies Development
Authors: Vilkova T. Yu.
Published: August 2020

The paper shows that ensuring access to justice is enshrined in the constitutions of most UN member states. The specificity of the Russian constitutional norm lies in the fact that ensuring access to justice for victims of crimes is imposed on the state as its duty. In criminal proceedings, this obligation is realized through the activities of the preliminary investigation bodies, the prosecutor, and the court. The author proposes measures aimed at building pre-trial proceedings that effectively ensure access to justice: refusal from the stage of initiation of a criminal case and indicating the preliminary investigation from the moment of registration of a crime report; empowering the prosecutor to initiate criminal proceedings, direct investigations and bring charges; expansion of judicial control in pre-trial proceedings; development of effective simplified and accelerated procedures in preliminary production; supplementing the grounds for termination of a criminal case, criminal prosecution by the inexpediency of criminal prosecution. It is shown that the introduction of digital technologies in the criminal process, including the establishment of digital interaction between state bodies and the population through a single secure digital online platform, should become an independent direction for improving pre-trial proceedings; creation of a mechanism for filing a crime report through a special online service; automatic registration of applications and determination of the direction of their movement using the capabilities of artificial intelligence; introduction of an electronic criminal case; use of semantic neural networks, computer vision, data clustering, etc. in the criminal process.

Authors: KILIÇGÜN Hasan
Published: August 2020

In this study, in vitro antioxidant activity and chemical content of different concentrations of Asparagus L. plant, growing naturally in Çayırlı District of Erzincan Province, were investigated. It was observed that Asparagus L. plant had antioxidant activity in all concentrations of parameters in which antioxidant activity was determined in vitro. However, the best activity was at a concentration of 4%. As a result of the chemical content analysis, it showed a linear increase in the phenolic content depending on the concentration, and the idea that the antioxidant activity is related to the phenolic content. On the other hand, the low Na content of asparagus can be used as an important food source for blood pressure patients. Being rich in terms of potassium, calcium, magnesium and phosphorus content shows that it may be a good alternative to cultivated plants. The fact that asparagus contains iron, copper, zinc and manganese also shows that the plant is rich in mineral substances. In addition, its high vitamin C content suggests that vitamin C is one reason why asparagus has an antioxidant effect. When the data obtained in this study were evaluated; Asparagus shows that it contains a significant amount of bioactive compounds, especially antioxidants that have beneficial effects on human health, and is a nutritionally well-balanced edible plant.

Role of Bacterial Secretion Systems and Effector Proteins – Insight into the Pathogenicity Mechanisms in Aeromonas
Authors: Matys Joanna , Turska-Szewczuk Anna , Sroka-Bartnicka Anna
Published: August 2020

Gram-negative bacteria have developed several nanomachine channels known as type II, III, IV and VI secretion systems that enable export of effector proteins/toxins from the cytosol across the outer membrane to target host cells. Protein secretion systems are critical to bacterial virulence and interactions with other organisms. Aeromonas utilize various secretion machines e.g. two-step T2SS, a Sec-dependent system as well as one-step, Sec-independent T3SS and T6SS systems to transport effector proteins/toxins and virulence factors. Type III secretion system (T3SS) is considered the dominant virulence system in Aeromonas. The activity of bacterial T3SS effector proteins most often leads to disorders in signalling pathways and reorganization of the cell cytoskeleton. There are also scientific reports on the pathogenicity mechanism associated with host cell apopotosis/pyroptosis resulting from secretion of a cytotoxic enterotoxin, i.e. the Act protein, by the T2SS secretion system and an effector protein Hcp by the T6SS system. Type IV secretion system (T4SS) is the system which translocate protein substrates, protein-DNA complexes and DNA into eukaryotic or bacterial target cells. In this paper, the contribution of virulence determinants involved in the pathogenicity potential of Aeromonas is discussed. Considering that the variable expression of virulence factors has a decisive impact on the differences observed in the virulence of particular species of microorganisms, it is important to assess the correlation between bacterial pathogenicity and their virulence-associated genes.

Diante do contexto histórico de surgimento do modo de produção capitalista e da consolidação dos Estados nacionais, o Estado revela-se um agente essencial para a continuidade do desenvolvimento do sistema capitalista. Como base da estrutura de organização e funcionamento do Estado, o direito também está incluído no conjunto de elementos mantenedores da construção do risco. No entanto, diante deste cenário irrefutável, como a prática educativa da ciência do direito tem se comportado e reproduzido diante da crise socioambiental? O objetivo deste trabalho é analisar a necessidade de uma prática educativa interdisciplinar do Direito Socioambiental em face da sociedade de risco e da crise ecológica. Como metodologia, faz-se uso da combinação dos métodos de abordagem dialético e indutivo, dos métodos de procedimento monográfico e comparativo, e das técnicas de pesquisa bibliográfica e documental. Conclui-se que as modificações necessárias no Direito perpassam, necessariamente, pelo diálogo com outras disciplinas e devem abarcar também a prática educativa no seu ensino.

Актуальность исследования обусловлена отсутствием экспериментальных данных, устанавливающих связь между субмикроскопическими свойствами (свойствами III рода) и макроскопическими свойствами I рода. Такая взаимосвязанность, являющаяся фактором влиянияна отношение «микроструктура–прочность», может способствовать дальнейшим успехам в решении вопросов ресурса. Цель исследования заключается в установлении влияния циклических термических нагрузок на среднеквадратичные смещения атомов как показатель прочности межатомных связей и микроповрежденности металла пароперегревательных труб. Объектом исследования являются образцы из околошовных зон однородного сварного шва, выполненного из жаропрочной перлитной стали 12Х1МФ. Методы: физическое моделирование условий эксплуатации путем воздействия на образцы циклами термической нагрузки в электропечи МИМП-10УЭ, рентгенометрия образцов, оценка внутренних структурных напряжений на рентгеновских дифрактометрах ДРОН, морфология поверхности с помощью портативного электронного микроскопа типа PENSCKOPE. Результаты.Установлено влияние циклических термических нагрузок на среднеквадратичные смещения атомов. Показано, что в результате термического влияния прочность межатомных связей увеличивается. Проиллюстрирована корреляция между субмикро- и макроскопическими характеристиками прочности, и показано, что амплитуда тепловых колебаний атомов, являясь характеристикой прочности межатомных связей, может быть диагностическим признаком накопления и развития повреждаемости металла. Уменьшение амплитуды среднеквадратичных смещений атомов при термоциклировании объяснено на основе гипотезы о возникновении твердых растворов замещения в результате процесса азотирования поверхности молекулярным азотом атмосферного воздуха. В рамках этой гипотезы показано, что одним из механизмов осцилляции внутренних напряжений I рода при термоциклировании может быть процесс азотирования поверхности, приводящий к организации в многокомпонентных легированных сталях сложных связей «металл–неметалл», направленных на поддержание устойчивости системы твердых растворов.

Актуальность. В районах добычи нефти и газа в связи с интенсивным развитием распределенной энергетики можно прогнозировать появление активных потребителей, использующих работающие на попутном нефтяном газе газотурбинные установки. При этом представляется недостаточно изученным вопрос переходных процессов, возникающих при подключении активного потребителя к системе электроснабжения нефтегазодобывающего предприятия. При сильных возмущениях режима при условии наличия нелинейных элементов переходные процессы могут завершиться устойчивыми хаотическими колебаниями – аварийным режимом работы электросистемы. Таким образом, существует необходимость изучения подключения активного потребителя к централизованным системам электроснабжения в районах добычи нефти и газа. Цель исследования: рассмотрение переходных процессов, возникающих при включении электрических систем активного потребителя и нефтегазодобывающего предприятия на параллельную работу. Объекты исследования: электрические системы активного потребителя и нефтегазодобывающего предприятия. Методы. Переходные процессы в электрических системах активного потребителя и нефтегазодобывающего предприятия исследуются путем компьютерного моделирования в программном пакете Simscape Power Systems (Matlab). В компьютерной модели при построении структурных схем электросистем, выборе мощности элементов и уровня напряжений использованы основы электроснабжения промышленных предприятий. Расчет значений параметров элементов электросистем выполнен на основе теории электрических машин и теоретических основ электротехники. Результаты моделирования показывают при включении методом точной синхронизации генератора активного потребителя на параллельную работу с внешней системой нормальный переходный режим длительностью 4 секунды. При несинхронном включении генератора в электросистеме возникают устойчивые хаотические колебания. На хаотические колебания указывает апериодический характер изменения во времени значений частоты, напряжения и мощности, а также нестранный хаотический аттрактор напряжения с положительным показателем Ляпунова 0,44. При хаотическом режиме работы на шинах промысловой подстанции диапазон изменений значений активной мощности составляет 18 кВт, частоты - 1,5 Гц, напряжения – 400 В.

Актуальность исследования обусловлена тем, что при количественном определении состава веществ все большую популярность приобретает цифровой цветометрический анализ. Это оптический аналитический метод, в котором первичным измерительным преобразователем является оптод, полученный из реагентов, иммобилизованных в твердотельную матрицу. При взаимодействии с определяемым компонентом в пробе оптод изменяет цвет; интенсивность окраски оптода пропорциональна количеству определяемого компонента. Полученный таким образом аналитический сигнал необходимо оцифровать и представить в одном из существующих цветовых пространств для формирования значения измеряемой величины. В научно-технической литературе не существует обоснованных рекомендаций, которые позволяли бы на систематической основе выбирать наиболее подходящее для конкретных требований цветовое пространство (модель). Цель: способствовать решению проблемы выбора такой цветовой модели для организации цифрового цветометрического анализа, которая для заданного набора аналитов обеспечивает наилучшие значения характеристик построенных для них градуировочных зависимостей аналитических сигналов. Объекты: используемые при цифровом описании цвета стандартные цветовые модели RGB, HSL, XYZ и L*a*b*. В качестве определяемых веществ были использованы тяжелые металлы: серебро, медь, железо, кобальт, хром, никель и сумма тяжелых металлов. Методы. Предложен и экспериментально обоснован с помощью агрегирования предпочтений метод выбора стандартной системы (модели) представления цвета, обеспечивающей проведение цифрового цветометрического анализа с наилучшими возможными значениями набора характеристик градуировочных зависимостей получаемых аналитических сигналов. Результаты. Метод позволяет выбирать стандартную цветовую модель, наилучшим образом подходящую для проведения цифрового цветометрического анализа, что, в свою очередь, способствует повышению достоверности цифрового цветометрического анализа.

Актуальность исследования обусловлена необходимостью всестороннего изучения процессов, ответственных за изменения биогеохимического режима арктического региона. Увеличение темпов деградации прибрежной и подводной мерзлоты на Восточно-Сибирском шельфе приводит к вовлечению в современный биогеохимический цикл большого объема ремобилизованного органического углерода. Изучение особенностей его транспорта и преобразования в системе суша–шельф играет важную роль для оценки функционирования крайне хрупкой арктической экосистемы. Цель: изучение геохимических характеристик органического вещества, прослеживаемых по профилю от береговой зоны к континентальному склону моря Лаптевых с применением метода Rock-Eval и оценка их взаимосвязи с литологическими свойствами вмещающих осадков. Объектом исследования явились пробы донных осадков, взятые с поверхностного горизонта (0–2 см). Отбор проб проводился в морских арктических экспедициях 2018–2019 гг. на НИС «Академик Мстислав Келдыш». Результаты. На основе результатов пиролитического анализа дана геохимическая характеристика органического вещества, содержащегося в донных осадках моря Лаптевых. Органическое вещество, экспортируемое с речным стоком и продуктами береговой эрозии, характеризуется относительно низким кислородным (OI) и водородным (HI) индексами в прибрежной зоне и на глубинах до нескольких десятков метров. В районе среднего шельфа существенное влияние на состав органического вещества, по всей видимости, оказывает снос осадочного вещества с Новосибирских островов, где активно действуют термоабразионные процессы (снижение значений HI и увеличение OI). Высказано предположение, что для продуктов, выносимых речным стоком, и продуктов эрозии берегов характерны различные пиролитические параметры, определяемые методом Rock-Eval (в частности, значения HI, OI и Tpeak).

Published: August 2020

In today’s globalizing world, information technologies are used in every field of life, and using these technologies in foreign language teaching has become a necessity rather than an option. Enabling learners who frequently use information technology tools in their daily lives to benefit from these technologies while learning a foreign language will have positive effects on their learning and motivation to learn. Information technologies are also used in the field of teaching Turkish as a foreign language, which has gained importance day by day. However, although endless opportunities are provided to the instructors by information technologies, it is seen that these technologies are not utilized sufficiently. In this study, in which qualitative research approach was adopted, information technologies used in foreign language teaching were examined through literature review and technology tools used in teaching Turkish as a foreign language were brought together. In this context, the aim of this study is to provide the instructors with detailed information about the information technology tools used in this field, to increase their awareness about these tools, and thus to contribute to technology enriched teaching of Turkish as a foreign language.

In this study, social studies teachers working in Serdivan district of Sakarya province were asked about their opinions on virtual reality, 360-degree videos and virtual museum, it was ensured that they made a museum visit via the “360-Degree Video Based Virtual Museum Application (360DVVMA)”, and their views were examined in depth. A semi-structured interview form was used as the data collection tool in the research. 2 descriptive question items to be asked to the teachers before implementation and 5 questions items to be asked after the implementation were prepared about the virtual museum application. The question items were submitted to expert opinions, required changes were made to the items, and the semi-structured interview form was finalized. According to the findings of the study, most of 9 social studies teachers knew about the concept of virtual museum and benefited from virtual museum applications in their classes, and 4 of them had never heard the concept of virtual reality before. 5 teachers stated that they had only heard of the concept but had no experience before and 360DVVMA could be used in the classes. Furthermore, the teachers emphasized that if 360DVVMA was used in instructional processes, it would provide equal opportunities in education for students who do not have the opportunity to go to museums as well as offering a great contribution to their academic development.
