Authors: Noureddine Sarir , Morsli Sebaa , Tayeb Allaoui , Mouloud Denai
Published: December 2021

This paper focusses on the design of optimal control strategies for a variable-speed wind energy system based on Permanent Magnet Synchronous Generator (PMSG). The fractional order PI controller, denoted PIλ, is an extension of the classical PI controller, which provides greater flexibility, better performance and robustness, however the tuning of the controller parameters is challenging. In this work, Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) provide approximate solutions to various problems and form a good optimization. In our system, they are used to have the PI regulator parameters and tune the parameters of the proposed controllers. The proposed controllers have been applied as maximum power point (MPPT) controllers for the wind turbine and to regulate the PMGS currents under variable weather conditions and. The results show that, among all these controllers, the fractional order PI controller optimized by the PSO leads to better performance in terms of the transient response characteristics such overshoot, rise time and settling time.
Socio-economic inequality as a key challenge of our modernity
Authors: Butkaliuk Vitalina A.
Published: December 2021

The article is devoted to the study of the causes, essence and social consequences of socio-economic inequality in the modern world. On the basis of an economic-sociological approach, the author investigates the evolution of this phenomenon from the beginning of the implementation of neoliberal reforms to the present. The article proves that the key reason for the intensification of the polarization of income and wealth in recent decades has been the fundamental transformations of the sphere of labor and employment, as well as other economic and political measures implemented within the framework of introducing the principles of neoliberalism into economic practice. The declining share of the labor income within the national income, the blurring of the link between productivity and wage growth, the dismantling of the welfare state and weakening trade unions are the result of the neoliberalization of the global economic system and key drivers of income and wealth differentiation and our modernity of labor inequality.The article focuses on the study of inequality in the context of the COVID-19 pandemic and the current COVID-crisis. The author comes to the conclusion that the growth of inequality and other social problems as a result of the pandemic was determined mainly by the socio-economic policies of the states of the pre-pandemic period. The COVID-19 pandemic acted as a social x-ray that revealed to the worlds population the real state of modern social institutions.

Ecofeminism in Film Adaptations of Lesia Ukrainka’s Forest Song
Authors: Andrianova Anastassiya
Published: December 2021

This article off ers a pioneering ecofeminist study of Viktor Ivchenko’s Lisova pisnia (1961) and Yurii Illienko’s Lisova pisnia. Mavka (1980), two Soviet Ukrainian film adaptations of Lesia Ukrainka’s eponymous fairy-drama (1911; Forest Song). It focuses on the interrelated depiction of gender and nature along with the drama’s ideological and material aspects: androcentrism and deforestation. The production of both fi lms coincides with, and arguably refl ects, what Marko Pavlyshyn describes as “the emergence of a conservationist consciousness” in the USSR in the 1960s. The article’s goal is therefore twofold – to bring new ecofeminist insights into Ukrainian fi lm studies and to raise eco-awareness about the Volyn Polissia, which provides the setting for Ukrainka’s drama and its adaptations, and currently faces environmental devastation from illegal amber mining.
The Reception of Lesia Ukrainka’s Works in German: The Significance of the Concept of “Struggle”
Authors: Lysetska Nataliia
Published: December 2021

The article examines individual German translations of works by Lesia Ukrainka in various genres, which activate the concept of “struggle.” To establish the linguistic and stylistic analogues, coincidences, and diff erences of the translated works, their typological comparison with the original Ukrainian sources was carried out. It was found that key motifs in the works of Lesia Ukrainka, such as aff ection, resilience, courage, confrontation, and great strength of will and spirit are factors that form the concept of “struggle.” The conceptual meanings and axiological values of the concept of “struggle” created by the poetess are: internal strength and independence; free choice, freedom, and liberty; the desire to have freedom and longing for it as the beginning or continuation of the struggle, a sign of insubordination, the spirit of disobedience; the word as a future weapon for the native language and Ukraine; the desire to prevail; the antithesis of death, sad thoughts, obedience, and others. The analysis revealed that there are some linguistic and stylistic diff erences in the analyzed German translations that are related to the peculiarities of German grammar and word formation. The selection of German equivalents sometimes further reinforces the emphasis of the original text. The concept of “struggle” in Lesia Ukrainka’s works in the analyzed translations into German by well-known translators fully reveals the conceptual picture of the author’s works and expands the possibilities of the reception of Ukrainian linguistic culture for German-speaking readers.
Playing Upon Biographical Myths: William Shakespeare and Lesia Ukrainka as Characters in Contemporary Drama
Authors: Vysotska Natalia
Published: December 2021

The article sets out to explore two plays by contemporary playwrights, one American (Don Nigro, Loves Labours Wonne), the other Ukrainian (Neda Nezhdana, And Still I will Betray You), focusing on William Shakespeare and Lesia Ukrainka, respectively, within the framework of “the author as character” subgenre of fictional (imaginative) biography. Accordingly, the article considers the correlation between the factual and the fi ctional as one of its foci of attention. Drawing upon a variety of theoretical approaches (Paul Franssen, Ton Hoenselaars, Ira Nadel, Aleid Fokkema, Michael MacKeon, Ina Shabert and others), the article summarizes the principal characteristics of “the author as character” subgenre and proceeds to discuss how they operate in the dramas under scrutiny. The analysis makes it abundantly clear that in Nigro’s and Nezhdana’s plays the balance between fact and fi ction is defi nitively tipped in favor of the latter. By centering their (quasi) biographical plays on highly mythologized artists of national standing, both dramatists aimed at demythologizing these cult fi gures, inevitably placing them, however, within new mythical plots combining a Neo-Romantic vision of the artist as demiurge, with a Neo-Baroque as well as fin de siècle apology of death and a postmodern denial of one objective reality.

Authors: Meza Paulina
Published: December 2021

El objetivo general de esta investigación es determinar la variación de los problemas de escritura identificados en ensayos argumentativos producidos por estudiantes de primer año de tres carreras de pedagogía de una universidad chilena. Para ello, en el marco de una investigación cualitativa y un diseño no experimental, analizamos un corpus constituido por 12 ensayos argumentativos. Para analizar este corpus utilizamos una rúbrica analítica que fue validada por distintos especialistas. Entre los principales resultados destacamos que, en general, los estudiantes de Pedagogía en Castellano y Filosofía obtienen mejores resultados que los de Pedagogía en Educación Diferencial y de Pedagogía en Educación General Básica.  Además, pudimos identificar las dimensiones que representan mayores dificultades para los estudiantes al momento de desarrollar un ensayo argumentativo. Ellas son: referencias bibliográficas, puntuación y cohesión en Pedagogía en Educación Diferencial y Pedagogía en Educación General Básica. Los ensayos de Pedagogía en Castellano y Filosofía, por su parte, no evidencian dimensiones que no alcancen el porcentaje mínimo de aprobación. Finalmente, nuestros resultados pueden servir como insumo para sustentar una didáctica de la escritura en carreras de formación de profesores, pues nuestros resultados podrían entregar pistas sobre los elementos del ensayo que deberían trabajarse con mayor dedicación en las carreras consideradas en esta investigación.
Escrita de roteiros: a produção de um audiovisual na escola e a escrita sobre sua aprendizagem
Authors: Galvão Janaína Aguiar Mendes , Tiburzio Vera Lucia Bonfim
Published: December 2021

Este artigo analisa uma proposta de atividade escolar com o objetivo de constitui-la enquanto estratégia para alterar a relação de licenciandos com a escrita, usando gêneros do discurso (BAKHTIN, 2006) que permitem uma compreensão mais simples dos propósitos de produção e parecem mais afins aos interesses espontâneos da juventude. Para embasamento teórico sobre a escrita escolar e universitária, utilizamos uma série de textos (BARBOSA, 2013; GERALDI, 1999 e 2018; COSCARELLI, 1998; DE PIETRI, 2007; LARROSA, 2002; RIBEIRO, 2015) que articulam problemas antigos aos contemporâneos, como o advento das tecnologias de informação e comunicação (TIC), sobre este objeto de estudo. O foco é analisar o processo de escrita de roteiros e a produção de minidocumentários. Posteriormente, contrastar a primeira e a segunda produção audiovisual para destacar mudanças nos parâmetros para representação da escola, da relação professor-aluno, da importância de despertar nos alunos o interesse pelas atividades. Os resultados encontrados demonstram que os textos audiovisuais apresentam informações e reflexões que se apagam no texto escrito, mas podem considerar-se indícios de autoria. Os documentários foram realizados por universitários do curso de Licenciatura em Ciências Biológicas da Universidade Federal do Triângulo Mineiro (UFTM) como atividade do PIBID, numa escola municipal de Uberaba-MG, em parceria com a disciplina de Ciências no Ensino Fundamental II.
Explorando operações discursivas na leitura de um artigo científico do campo da educação matemática: contributos para a reflexão sobre produção de conhecimento
Authors: Mena Thiago
Published: December 2021

Neste trabalho, proponho-me a estudar o funcionamento de algumas operações discursivas presentes em um artigo científico do campo da Educação Matemática, de modo a viabilizar uma leitura crítica do conhecimento ali apresentado. Para tanto, mobilizo categorias de análise provenientes de três vertentes teóricas distintas: a Semântica Linguística, com as noções de posto, pressuposto e subentendido, estudadas por Oswald Ducrot; a Linguística Textual, com as noções de referenciação e avaliatividade, abordadas por Paulo Roberto Gonçalves Segundo; e a Metaforologia, com as noções de Metáfora Situada e Conceptual, trabalhadas por George Lakoff, Mark Johnson e Solange C. Vereza. O artigo analisado foi destacado de um corpus produzido na pesquisa que realizo no âmbito do programa de Doutorado em Educação da Faculdade de Educação da USP. Tal artigo, intitulado “Qual é o tempo médio das aulas de Matemática nas escolas públicas de periferia?”, foi publicado em 2004 nos anais do “II Seminário Internacional de Pesquisa e Estudos Qualitativos: a pesquisa em debate”. A análise dos dados permitiu explicitar como certos enunciados são construídos de modo a provocar efeitos de sentido que encobrem contradições, concepções equivocadas e posicionamentos autoritários no tocante ao controle da dialogicidade do texto, além de veicular determinada acepção de Educação enviesada por conteúdos positivistas e idealistas. Tais resultados evidenciam que os estudos discursivos podem contribuir para o avanço das produções científicas materializadas em textos acadêmicos do campo da Educação Matemática.

About characteristic features of naftides in connection with the process of formation of deposits
Authors: Punanova Svetlana
Published: December 2021

Studies have been carried out to assess the qualitative features of fluids, aimed at identifying the regularities in the differentiation of the properties of naphthides during the formation of hydrocarbon deposits outside anticlinal structures. Due to the exhaustion of hydrocarbon reserves associated with anticlinal traps, the main attention is paid to the composition of fluids confined specifically to non-anticlinal structures – to traps of a combined structure. Physicochemical properties, trace element (TE) composition, phase states of naphthides in deposits affected by hypergenetic or catagenetic processes have been analyzed using specific examples; in regions with a possible additional inflow of hydrocarbons (Romashkino group of fields in the Republic of Tatarstan); in the crystalline basement of sedimentary basins. The results of the analysis make it possible to predict the characteristic features of fluids in traps of various types at certain levels of the processes of oil formation, secondary transformation and destruction of accumulations, mainly due to the tectonic regime of the sedimentary basin. With prolonged lateral migration, at great depths with good isolation from surface weathering agents, light oils, depleted in TE, more often of nickel specialization, are found in lithologically and stratigraphically screened traps, and gas condensate accumulations are possible. At shallow depths with poor regional or local seals, heavy, highly viscous hypergene-transformed oils, natural bitumens with high concentrations of industrially significant metals V, Ni, Co, Mo Cd, U were found in traps of pinch-out zones and various types of trap screening. tectonically-screened traps) with a multiphase filling of traps and, at the same time, the influence and inflow of deep ones, i.e. more catagenically transformed fluids, it is possible to detect light oils of the nickel type or gas condensates enriched with elements of “magmatic emanations” – As, Hg, Al, B, rare earth elements. Oils filling combined traps in the crystalline basement within platform oil and gas basins, as a rule, do not differ in their compositional peculiarities in comparison with oils in overlying or adjacent parts of the sedimentary section.

Authors: Shakirzyanov Artur , Petrova Daria , Sofinskaya Oksana
Published: December 2021

The study of the influence of technogenesis on the state of surface waters in urbanized areas is one of the most urgent ecological and social problems. For processing and analysis of hydrochemical indicators of surface water bodies of Kazan for the period 2014–2020 the generally accepted stasticial indicators, as well as the methods of multivariate statistics were used. Hydrochemical models were built using the ArcGisMap software package. The data were grouped using the cluster analysis method separately for each hydrological season with the allocation of 6 groups of hydrochemical components in relation to the maximum permissible values. It has been revealed that the minimum technogenic load on the surface waters of the city falls on the spring period. Based on the analysis of the results obtained, an ecological and hydrological assessment of the state of surface waters was carried out. It was showed that the water bodies of Kazan are classified as unfavorable water bodies.

Published: December 2021

The article is devoted to the generation and accumulation systems in the territory of the Crimean-Caucasian segment of the Alpine folded system. An area of prolonged and stable sagging in the Mesozoic and Cenozoic – the Azov-Kuban Trough, which is a typical foreland basin – is distinguished within this segment. According to the results of geological and geochemical studies and modelling, depocentres are identified in this area, consolisated in four generative and accumulative hydrocarbon systems: Triassic-Jurassic, Cretaceous, Eocene and Maikop. Chemical-bitumenological, pyrolytic and coal petrology analysis of rock samples were carried out to assess geochemical conditions of oil and gas content in Meso-Cenozoic sediments. The modelling results made it possible to study and model the elements and processes of hydrocarbon systems in the Meso-Cenozoic in the Western Crimean-Caucasian region. It has been established that the extended catagenetic zoning is typical for these areas, which is caused by high rates of sedimentation and sagging, and large thicknesses of oil-bearing sediments in the source of oil formation, accordingly. The degree of organic matter depletion characterized the residual potential of the oil and gas source strata, was investigated. It is important for predicting and assessing the possibility of hydrocarbon generation.

Published: December 2021

This study introduces results of lithological, petrophysical and geochemical investigation of Lower Cretaceous (K1) and Middle Jurassic (J2a-b) rocks of East Pre-Caucasian basin.
According to pyrolytic and bituminological studies method of separate determination of kerogen and bitumen concentration been developed. In accordance with this method differentiation of organic matter components in different lithotypes of rocks been described. Also relationship between bitumen and kerogen concentrations been revealed.
The majority of samples have poor to fair organic richness and poor source potential. Kerogen type is commonly presented by type III and stages of maturity characterized by stages PC3 to MC3. Bitumen compounds have low concentrations of asphaltenes and aromatic hydrocarbons and mainly contains light and heavy resins.
Based on petrophysical and geochemical studies a close relationship between the concentration of organic carbon and the weight concentration of potassium nuclides was obtained. This relationship indicates that kerogen in the sediments under consideration is associated with clay minerals, which is also confirmed by the mineral composition of the rocks.
Interpretation of electrical logging data from the Hettangian-Aalenian terrigenous reservoirs in the Southeast of Western Siberia
Authors: Loktionova Olga , Kalinina Lyudmila , Mikhaylov Igor
Published: December 2021

In the southeast of Western Siberia, the most studied are the Upper Jurassic deposits, most of the oil and gas fields being confined to them. However, the probability of discovering new hydrocarbon deposits in the Upper Jurassic horizons is extremely small. Therefore, of great importance is finding new hydrocarbon deposits in less studied deep-lying complexes.
The article considers the development of a criterion for determining the saturation type of the terrigenous reservoirs in the Hettangian-Aalenian deposits in the southeast of the West Siberian sedimentary basin. We use the example of the Ust-Tym megadepression, a large depression located in the central part of the Tomsk region. The Lower and Middle Jurassic sections are represented by the Urman and Togur formations, Salat formation (Peshkov formation is its isochronous analogue) and Tyumen formation, and characterized by the alternation of predominantly sandy (potential reservoirs) and argillaceous-carbonaceous (seals) sequences. In the studied interval, tests were carried out in just a few wells, for which reason the identification of deposits and promising objects is complicated. Determining the type of reservoir saturation will significantly improve the assessment of oil and gas potential.
As a result of interpreting lateral logging sounding data, the geoelectric parameters of the invasion zone and undisturbed formation were reconstructed for the Lower Jurassic and Aalenian deposits. Based on the well logging data interpretation by means of numerical inversion, we obtained the criterion for the saturation type of the reservoirs (Ju11-17) in the Hettangian-Aalenian complex. The boundary resistivity values for the oil-saturated reservoirs vary from 8 to 20 ohm∙m, while for the water-saturated ones they do not exceed 5 ohm∙m.

Objectives: We aimed to evaluate the anesthetic approaches of patients who underwent surgery in our hospital during the early COVID-19 pandemic period. Methods: All patients admitted to general surgery (GS), orthopedics, neurosurgery (NS), urology, cardiovascular surgery (CVS), thoracic surgery, ear nose throat, and plastic and reconstructive surgery at the operating rooms in our hospital in early pandemic periods were scanned retrospectively. Demographical data, surgical indications, urgency, anesthetic methods, and complications are evaluated. Anesthetic methods used in the operations were examined as general anesthesia, regional anesthesia, and sedoanalgesia. In addition, patients’ hospital stay period, intensive care unit admission rate, 30 days mortality, and COVID-19 positivity after surgery were examined. Results: Two hundred and ninety patients were admitted for operation in our hospital during a pandemic. CVS, Orthopedics, and GS were departments that admitted the most number of patients with ratios of 27.2%, 26.2%, and 25.2% respectively. The patients who underwent emergency surgery were seen in the CVS with 79 patients and the orthopedics with 73 patients. In anesthesia management, the application rate of general anesthesia was 44.1%, regional anesthesia 33.1%, and sedoanalgesia 22.8%. Totally 61 patients were admitted to ICU. According to surgical branches, 30-day mortality rates were determined as 8.3% in NS, 6.6% in GS, 3.8% in CVS, and 2.7% in orthopedics respectively. Four patients were postoperative COVID-19 positive in total. Conclusions: Anesthetic approaches in surgical patients may affect the length of hospital stay, referral to the intensive care unit, and mortality in the early period of the COVID-19 pandemic.

The article is devoted to the vibration characteristics of one element, namely the rolling bearing andmethod, which is based on both bench and field tests and proven to be effective to identify items of axlebearing. The method is based on static kurtosis parameter, which remains constant for good bearing,irrespective of load and speed, but changes with the development of damage. The extent of damage can beestimated from the distribution of this parameter in the selected frequency intervals. Thus, the evaluation ofbearing condition can be conducted with minimal use of information about its past state. Most other methodsused to detect damage in a significant advantage of the data analysis, so this method could be a significantachievement in the field of detection of defects in the bearings or at least will allow you to create simple andcheap method. Like most other simple methods of damage detection, this method does not allow to defineprecisely the nature of the defect and to obtain such information it is necessary to use more sophisticateddiagnostic methods.

The problem of machining structural elements with removal of metal layers with thickness less than 0.01 mm by carbide tools, when the conditional radius of the blade rounding is less than or equal to the thickness of the cut layer, is considered. These cutting conditions can be considered constricted which requires research into cutting forces and chip shape. The problem of recording and measuring small cutting forces arising during blade machining of small grooves that serve for gas drainage in the manufacture of rubber products is solved. To measure forces, a lever fixed in a universal dynamometer, which has a supporting support with small friction, is used. Value of force moment measured with dynamometer can be used for optimization of cutting conditions, selection of tool geometry when processing small relief elements. Dependences of lever system cutting forces and displacements on the use of lubricant-cooling liquids, values of front angles during planing and milling with small-size tools are investigated. Experimental discrepancies between theoretical calculations of cutting forces according to classical and modern reference data and fixed results with the use of cutting liquids during cutting with small values of feed for carbide tools are found

The modern stringent requirements for fuel efficiency, exhaust gases toxicity and dynamic performance can only be met by equipping thermal power plants with modern control and regulation systems. Thermal power plants based on internal combustion engines have found the greatest application. They are used in different fields --- automobile and railway transport, agricultural, road-building and forestry machines, in ship-building, aviation, stationary power plants. The analysis of the main directions for further improvement of thermal power plants with internal combustion engines and their automated control and regulation systems has been carried out. Among these directions are an expansion of functional capabilities in such systems, improvement of control and regulation processes quality and their use at adaptation of thermal power plants to work on alternative fuels. The important aspects for improvement of thermal power plants with internal combustion engines are the necessity of studying the working processes of engines and their systems in order to decrease the exhaust gases toxicity. The relevance of these systems research is shown and the evaluation of the current level in their development is made. A characteristic feature of modern control and regulation systems of thermal power plants is their widespread construction on modern microprocessor element base

A method of forming a spacecraft adapter layout to meet the requirements of dynamic compatibility by topological and parametric optimization methods
Authors: Borovikov A.A. , Tushev O.N.
Published: December 2021

At present, the developers of launch vehicles impose a requirement for dynamic compatibility of the spacecraft with the launch vehicle, which consists in limiting the lower boundary of the first transverse and first longitudinal fundamental (primary) frequencies of the natural vibrations of the spacecraft fitted with an adapter of relatively rigid base. One of the tasks that must be solved in order to meet this requirement is the development of the spacecraft adapter layout. The traditional process of designing the adapter consists in developing its design on the basis of analogues and carrying out verification analysis with subsequent refinement of the design to meet the strength and stiffness requirements. However, this approach takes a lot of time and is not adaptable to constant changes in the input data at the initial design stage. The article presents a technique allowing the adapter layout to be quickly designed. The layout is determined to a greater extent by calculations using the topological and parametric optimization methods. The application of the developed technique is shown on the example of the development of an adapter for a promising spacecraft. It should be applied in the early stages of design. The results obtained by the method should be used as input data and recommendations for the design of the adapter.

Published: December 2021

The paper describes a method developed for designing the trajectory of a spacecraft flight from the lunar surface to a given area of the Earth’s surface and analyzes a single-pulse flight scheme, in which the trajectory of a take-off lunar rocket is approximated by a single velocity pulse. The characteristics of the spacecraft entry into the Earth’s atmosphere are chosen so as to ensure that the conditions along the entry corridor during the ballistic entry are met and to ensure the landing of the reentry vehicle at a given point on the Earth’s surface. The criterion for optimizing the trajectory of the spacecraft return to the Earth is considered to be the value of the impulse that provides the spacecraft launch from the lunar surface. The method relies on the analysis of an auxiliary problem, the solution of which makes it possible to estimate the main properties of the investigated maneuver and find an initial approximation for the selected characteristics of the optimized trajectory.

The evaluation of methodological errors in measuring the temperature of nitride ceramics under unilateral heating by high-intensity heat flow was carried out. Simulation of thermal processes in the temperature sensor — sample system was performed using the Siemens PLMNX program. Various methods of fixing platinum-rhodium thermocouples with a diameter of 0.1 mm on the surface and inside the samples have been investigated. The regularities of the influence of the size of the hot junction, the presence of thermal cement, the shape of the grooves for fixing thermocouples on the methodological error of temperature measurement were investigated. Significant errors were revealed when installing thermocouples on the surface of the sample without violating its integrity. Recommendations for the installation of thermocouples were given. The results of the paper can be useful in the preparation of experimental samples for thermal tests on radiation heating stands.
