Author

Voloshina, Ludmila Nikolaevna, Demicheva, Vera Vladimirovna, Reprintsev, Alexander Valentinovich, Stebunova, Kira Konstantinovna, and Yakovleva, Tatyana Viktorovna

Abstract

The problem of creating self-established educational standards (SES) is considered by the authors associated with the need to ensure the quality of educational programs and quality of preparation of the future teacher to solve new professional problems. The present work is aimed at scientifically recognising the technology of designing SES. Research methods: theoretical (analysis, synthesis and modelling) and empirical: survey methods (questioning and interviewing). Based on the results of employers' satisfaction survey (n = 112), the quality of teacher training and self-assessment of the preparation of graduates of a pedagogical university (n = 123) to perform work functions were defined an algorithm for developing SES in the direction of 'Pedagogical education', including analytical and diagnostic, modelling and reflexive stages. In general, the technology of preparing and introducing an SES ensures the integration of pedagogical science and practice and the development of continuous pedagogical education in the context of a regional scientific and educational cluster.

Abstract

In the science of law legal definitions are considered as the semantic core, thanks to which a legal norm functions, and represent a reliable legal basis for further social transformations. In order to identify the characteristic features, properties, content of the concept of environment and its components, to establish their relationship, features of legal effect, the common, scientific and legal meanings of the definitions were compared. The methodological basis of the study was general scientific (analysis, synthesis, generalization) and special legal methods (formal logical, legal modeling method). Modeling the conceptual framework of the ecological legislation in Russia is not only of scientific but also of practical interest. It enables to identify the characteristic features, properties of the concept of environment, the relationship among its elements as a potential subject of further research contributing to in-depth study, identification of gaps and improvement of legislation. The legal model of environment contains a schematic and descriptive part, demonstrating the concept, system and its content, thanks to which environmental legal norms function that reflect the essence of legal regulation and state policy of Russia in the field of environmental protection and the use of natural resources, clearly shows its shortcomings and determines the directions to improve legislation.

Abstract

The stage of formation of organic agriculture has begun in Russia. According to the requirements of Russian legislation and international standards, organic agriculture provides for the production of organic products in conditions close to biological processes occurring in natural ecological systems. Organic agriculture should be based on a set of methods that ensure a viable ecosystem, safe food, healthy nutrition, animal health and social justice, and an organic product is a product that is produced in accordance with organic farming standards. The system of state regulation of organic production in Russia is insufficiently formed and does not fully meet the modern requirements of international standards. The purpose of the study is to assess the compliance of Russian legislation with the requirements of international standards in the field of certification of organic production. The laws introduce requirements for certification of only organic products themselves, which is insufficient to solve the tasks set by the state and the international community. The proposed model of ecological certification of organic production will meet the challenges in the field of organic agriculture, environmental protection, and organic products will meet international requirements and standards, which will contribute to the output of products on the Russian and international market.

Abstract

International and environmental law in Russia does not provide a preventive and precautionary approach to forestall degradation of the marine environment and the "polluter pays" principle at the present stage. The author proposes supplementing international environmental law in the investigated area with an approach based on the principle that the polluter not only pays but also restores. Improvement of approaches and principles of international law will be the basis for changing Russian legislation and legislation of other countries in order to prevent degradation of the marine environment. After an oil spill, the coastal waters of the seas and their ecosystems are the most vulnerable; therefore, the national legislation of states is primarily interested in legal regulation of marine environmental protection in case of oil and petroleum product spills. The legal obligation on oil and gas producing companies to carry out measures to remediate the marine environment will require them to finance scientific research, search and develop new technologies for the safe development of subsoil resources and restoration of the marine environment. This study is a comprehensive analysis of the scientific research results in the field of biology, environmental protection, protection of water bodies, marine environment, as well as international and Russian environmental law governing relations in the field of marine environment protection during the development of mineral deposits on the continental shelf, internal sea waters, in the territorial sea and the adjacent zone of the Russian Federation.

Abstract

In this study, the microstructural behavior of the advanced Ti-5.7Al-3.8Mo-1.2Zr-1.3Sn-0.15Si (VT8M-1) alloy during rotary swaging (RS) was investigated. VT8M-1 has increased heat resistance and is considered a replacement for the Ti-6Al-4V alloy. It was shown that, during RS, the evolution of the primary a phase is characterized by the formation of predominantly low-angle boundaries according to the mechanism of continuous dynamic recrystallization. The density of low-angle boundaries increases three times: from 0.38 µm−1 to 1.21 µm−1 after RS. The process of spheroidization of the lamellar (a + b) component is incomplete. The average size of globular a and b particles was 0.3 μm (TEM). It is shown that the microstructures after RS (ε = 1.56) and equal-channel angular pressing (ECAP) (ε = 1.4) are significantly different. The temperature–velocity regime and the predominance of shear deformations during ECAP contributed to a noticeable refinement of the primary a-phase and a more complete development of globularization of the lamellar (a+b) component. EBSD studies have shown that RS leads to the formation of a structure with a higher density of low- and high-angle boundaries compared to the structure after ECAP. The results are useful for predicting alloy microstructure in the production of long rods that are further used in forging operations. [ABSTRACT FROM AUTHOR]

Abstract

Discourse study in contemporary science is characterized by various approaches, whose integrative feature is the fact that this theoretical phenomenon is considered as a communicative activity and is caused by anthropocentric factors of speech generation. The representation of school discourse stimuli allows simulating the speech portrait of participants in educational activities. School discourse is a complex communicative phenomenon created by the subjects of the school educational process. It reflects the totality of accepted values and behavioral stereotypes in a particular socio-cultural space. The work aims to investigate the stimuli of school discourse. This work was conducted employing methods, such as 1) the free associative experiment; 2) quantitative analysis, which allowed identifying the actualization of the incentive perception based on quantitative data; and 3) discursive and conceptual analysis, which involved the identification of concepts, simulating them based on the conceptual totality of the means of their lexical representation in the usage. In the course of conducted study, about 600 native speakers of the Russian language were interviewed, and 9,440 associations were obtained for the school discourse stimuli. In the language consciousness of schoolchildren and teachers, associations for the “Family” stimulus were dominant, and the associative field of this stimulus was represented most broadly. The smallest number of associations was noted with regard to the “Evil” stimulus. The frequency of associations in the stimuli “Good”, “Happiness”, “Love”, “Friendship”, “Joy”, and “Labor” was approximately the same. The representation of school discourse stimuli reflects the value system, worldviews, moods, and assessments of recipients. Such a study was conducted for the first time.

35. Thermal Stability and Recrystallization of Titanium Grade 4 with Ultrafine-Grained Structure

Abstract

The paper examined annealing behavior of ultrafine-grained Ti Grade 4. The ultrafine-grained microstructure was produced by equal-channel angular pressing (ECAP) technique by using a Conform scheme and was characterized by a mean grain size of d=0.3 μm and non-equilibrium grain boundaries. The ultrafine-grained structure was found to be stable up to 400°C. The excellent thermal stability was attributed to a strain-ageing, i.e., the enhanced diffusion of interstitial solutes resulting in a formation of solute atmospheres at/near grain boundaries and dislocations. At 450–500°C, a rapid growth of strain-free grains was observed to occur. This process eliminated severely-deformed microstructure and gave rise to abrupt material softening. A further increase of the annealing temperature above 600°С resulted in precipitation of lenticular dispersoids as well as iron-rich globular β-particles. This surprising phenomenon promoted a subtle hardening effect.

Abstract

This article describes a method for analyzing hierarchies; identifies the problems with inconsistent judgments. The proof is given that the most effective tool allowing one to make the right decisions with inconsistencies is the introduction of the eigenvector on environmental planning and management. The Analytic Hierarchy Process (AHP) is a method for decision making, which includes qualitative factors. In this method, ratio scales are obtained from ordinal scales, which are derived from individual judgments for qualitative factors using the pairwise comparison matrix. This paper describes the applicability of a multicriteria decision-making method, specifically, the analytic network process.

Abstract

Актуальность исследования. Наноэлектромеханические системы, будучи высокочувствительными датчиками, имеющими малые размеры, и надежными в эксплуатации, находят все более широкое применение в нефтегазовой промышленности для мониторинга различных процессов в нефтедобыче - от разведки до повышения нефтеотдачи, а также при бурении скважин, очистке, фракционировании и переработке до вывода их из эксплуатации. Одним из примеров применения наноэлектромеханических систем является сейсмические исследование месторождений. Применение наноэлектромеханических систем позволяет улучшить производительность в дополнение к существенной экономии средств и времени для широкого спектра технологий нефтегазовой промышленности. Благодаря возможности непрерывного контроля эти технологии могут стать основой «умных» месторождений. Цель: построение математической модели, наиболее полно описывающей нелинейную динамику чувствительного элемента наноэлектромеханического датчика под действием знакопеременной нагрузки. Для этого необходимо учесть наиболее распространѐнные в настоящее время кинематические гипотезы, масштабные эффекты с помощью моментной теории упругости, нелинейную зависимость между напряжениями и деформациями, неоднородность материала, шумовые и тепловые поля. А также исследовать характер сложных нелинейных колебаний и выявить закономерности перехода их от гармонических к хаотическим. Объекты: геометрически и физически нелинейная нанобалка, описываемая кинематической моделью первого приближения, на которую воздействует равномерно распределенная знакопеременная поперечная нагрузка с гармонической составляющей, температурное поле и аддитивный внешний шум. Методы: вариационные методы, метод конечных разностей второго порядка точности для сведения системы нелинейных дифференциальных уравнений в частных производных к задаче Коши, метод Ньюмарка для решения задачи Коши, метод переменных параметров упругости Биргера для решения физически нелинейной задачи, метод вариационных итераций для получения аналитического решения двумерного уравнения теплопроводности. Результаты. Для получения аналитического решения теплопроводности применяется метод вариационных итераций. Построена математическая модель колебаний чувствительного элемента наноэлектромеханического датчика в виде размерно-зависимой балки, на которую действует равномерно распределенная поперечная нагрузка с гармонической составляющей. Помимо переменной нагрузки учитывалось влияние температурного поля и аддитивного внешнего шумового воздействия. Геометрическая нелинейность принята по теории Теодора фон Кармана (связь между деформациями и перемещениями). Для учета физической нелинейности материала балки применяются деформационная теория пластичности и метод переменных параметров упругости. Уравнения движения элемента механической системы, а также соответствующие граничные и начальные условия выведены исходя из принципа Остроградского-Гамильтона на базе модифицированной моментной теории с учетом гипотезы Эйлера-Бернулли. Выявлено, что температурное и шумовое поля уменьшают нагрузку, при которой происходит переход в хаотическое состояние системы. Переход от гармонических колебаний к хаотическим происходит по сценарию Рюэля-Такенса-Ньюхауза. The research relevance. Nanoelectromechanical systems, being highly sensitive sensors with small dimensions and reliable in operation, are increasingly used in the oil and gas industry for monitoring various processes in oil production, from exploration to enhanced oil recovery, as well as in well drilling, cleaning, fractionation and processing before decommissioning. One application example of nanoelectromechanical systems is seismic exploration. The use of nanoelectromechanical systems offers improved performance in addition to significant cost and time savings for a wide range of oil and gas industry technologies. With continuous monitoring capabilities, these technologies can become the foundation of smart deposits. The main aim of the research is a construction of a mathematical model that most closely describes the sensitive element nonlinear dynamics of a nanoelectromechanical sensor under an alternating load action. For this, it is necessary to take into account the most common kinematic hypotheses, scale effects using the modified couple stress theory of elasticity, the nonlinear relationship between stresses and strains, the material inhomogeneity, noise and thermal fields. And also to examine the complex nonlinear oscillations nature and identify patterns of transition from harmonic to chaotic. Objects: geometrically and physically nonlinear nanobeam, described by the kinematic model of the first approximation, which is affected by a uniformly distributed alternating transverse load with a harmonic component, the temperature field and additive external noise. Methods: variation methods, a second-order finite difference method for reducing the system of nonlinear partial differential equations to the Cauchy problem, the Newmark method for solving the Cauchy problem, the Birger method of variable elasticity parameters for solving a physically non-linear problem, the variation iteration method for obtaining an analytical solution of the two-dimensional heat equation. Results. The variation iterations method is used to obtain an analytical solution of thermal conductivity. An oscillations mathematical model for the sensitive element of the nanoelectromechanical sensor in the form of a size-dependent beam, on which a uniformly distributed transverse load with a harmonic component acts, is constructed. In addition to the variable load, the influence of the temperature field and additive external noise exposure were taken into account. The geometric nonlinearity is accepted according to Theodore von Karman theory (the relationship between deformations and displacements). To take into account the physical nonlinearity of the beam material, the deformation plasticity theory and the method of variable elasticity parameters are used. The motion equations of a mechanical system element, as well as the corresponding boundary and initial conditions, are derived from the Ostrogradsky-Hamilton principle based on a modified moment theory taking into account the Euler-Bernoulli hypothesis. It was revealed that the temperature and noise fields reduce the load at which the transition to the chaotic state of the system occurs. The transition from harmonic to chaotic oscillations occurs according to Ruelle-Takens-Newhouse scenario.
