Authors: Rogalev A. N. , Rogalev N. D. , Kindra V. O. , Grigoriev E. Y. , Makhmutov B. A.
Published: October 2019

Rising carbon dioxide concentration in the atmosphere is probably the main reason of global warming. The development of the oxy-fuel combustion cycles is a possible way to decrease the energy sector contribution in the emission process. However, an unusual composition and thermodynamic parameters of the working fluid cause the necessity of revision of the main equipment characteristics, especially for the supercritical carbon dioxide gas turbine. This study presents the method and the results of the flow path preliminary analysis for the new generation gas turbines working on carbon dioxide. The flow path shape with a constant root diameter of seven stages was chosen as the most reasonable due to cheap manufacturing. Influence of reaction degree of stages and velocity ratio on stage geometric parameters are revealed. It was found that the optimal reaction degree and velocity ratio are equal to 0.25 and 0.36 correspondingly. Thermal and constructive stages characteristics of the 350 MW turbine are determined.

Authors: Romanov D. O. , Yavorovsky Y. V.
Published: October 2019

Application of thermohydraulic dispatcher (THD) for district heating systems is, to some extent, limited due to insufficient information about its properties and features. At the same time this device has a potential to solve the problem of mutual dependence of heat consumers and to decrease electricity consumption in heat supply systems. This paper deals with experimental research and numerical simulation of THD with the aim of increasing the range of knowledge about its properties. Presented results describe already known properties such as near-to-zero differential pressure at THD and flow rates independence which were checked. Some new properties and peculiarities of THD were obtained during the investigation as well. Among them is differential pressure “variability”, hydrodynamic separation under higher velocity, similarity of thermohydraulic processes inside THD under similar velocities in manifolds of THD, absence of thermal stratification in mixing regime, dependence of secondary circuits supply temperature from the height level and secondary circuits return temperature.

Published: October 2019

Traveling-wave methods of the fault location prove their practical efficiency for the power transmission lines (TL) with an arbitrary configuration of any voltage class. This paper formulates algorithms to automate the process of the fault location in the TLs with a tree-like structure. The error of the simplified traveling-wave fault location (TWFL) algorithm based on the average propagation velocity of the transient signals (TS) is analyzed. A tabular algorithm for TWFL, which considers different propagation velocities of the TS in different segments of a hybrid network is proposed. An adaptive TWFL algorithm that considers the registration of the TSs with known places of their occurrence is proposed, to reduce the impact of the inaccuracy of the initial different network segments’ lengths and TS’s propagation velocity determination.

Published: October 2019

For a quantitative analysis of the organic matter content in the production waters of the energy-technological complexes of the Thermal Power Plant petrochemical enterprise, a simple, effective, affordable and very fast method was developed. Its essence is to determine the optical density at a 400 nm wavelength on a device such as a colorimeter. The correlation with the permanganate oxidation method is 98-99%. According to the presented method, the quantitative composition of organic substances in the alkaline spent regeneration solution of anion-exchange filters of the Thermal Power Plant (TPP) water treatment plant and in the return condensate from petrochemical enterprise was determined. For each water type, its own calibration schedule was constructed due to significant differences in the qualitative composition of organic impurities.

Authors: Filina O. A. , Tsvetkov A. N. , Pavlov P. P. , Radu D. , Butakov V. M.
Published: October 2019

This article describes a vibration model connected by individual nodes of a DC motor. The purpose of the article is a mathematical model allowing to predict the work of machines with a depreciation resource and search for ways to increase the information content of assessing the functioning of the rolling stock condition without dismantling them. Currently, the operational reliability of the DC motor is reduced after the development of the service life. Study and evaluation of the vibration effect on the brush-collector node. The main components of the DC motor (bearings, electrical brushes) are unrecoverable. Therefore, any interference with their normal operation leads to premature wear of the entire DC motor. Existing methods for life-extending maintain the operational reliability of a DC motor equal or close to the passport data for several years. This model allows vibration diagnostics without dismantling the DC motor and stopping the rolling stock. The mathematical model describes the oscillations of each node of the DC motor in the direction of movement of the rolling stock, showing the excess of the permissible value. After mathematical processing of the results, a machine reliability model under study is obtained (usually in the form of polynomials) as a function of the needed parameters – the influencing factors. Due to this model, pre-detected defects can save on repairs and maintenance in the future. This model is the basis of software for online diagnostics. The proposed model allows providing an objective use of repair and restoration compositions depending on the current technical condition, which will lead to an increase in the service life of the mechanism and savings in operating costs. On the one hand, extending the operating life of a DC motor should produce an economic effect, and on the other hand, technical measures to maintain operational reliability cause an increase in material costs.

Modified method of conductometric data analysis to calculate the degree of ionization and conductivity of micelles
Authors: Zueva O. S.
Published: October 2019

Methods for calculation of specific conductance of ions and micelles and the degree of micelle ionization using conductometric data in various approximations of the Debye – Hückel – Onsager theory were considered. The analysis of the existing calculation methods was carried out to identify their drawbacks and to suggest ways of their elimination. The calculation method of the micellar parameters on the basis of conductometric data using micellar size was modified, and a new formula for determining the degree of micelle ionization was obtained. All calculations using the modified method were performed in the first and the second approximations, and the newly obtained values of the micellar parameters are in greater agreement with the results of other studies. Based on the calculations performed, it was shown that the contribution of micelles to the total conductivity of micellar solution cannot be neglected, since at high concentrations the contribution of micelles exceeds the contribution of counterions and can exceed 50%.
Modified method of conductometric data analysis to calculate the conductivity of surfactant ions
Authors: Zueva O. S.
Published: October 2019

Methodology for simple analytical refinement of the equivalent electrical conductivities of surfactant ions and counterions was proposed in the framework of the Debye – Hückel – Onsager theory as applied to surfactant dispersions at various concentrations. The developed methodology is based on the use of the mathematical form for the concentration dependencies of the specific conductivity in the premicellar region and makes it possible to calculate the equivalent conductivities of surfactant ions both under infinite dilution conditions and near the CMC. One of the advantages of the described method is the possibility of calculating the ion conductivities in the presence of a minimum number of experimental points (formally, a straight line can be constructed and its tangent of the angle of inclination can be determined even by two points corresponding to region 0.2 CMC — 0.8 CMC). Using the values of the equivalent conductivities of surfactant ions and counterions calculated for the required concentrations, allows to determine the parameters of the solution more accurately, including the contribution of micelles to the total conductivity of the solution.

Published: October 2019

We demonstrate that the most efficient way to extinguish the short-circuit arc is extinguishing inside the camera with an arc extinguishing grid, which splits it into several smaller arcs. The active resistivity of these partial arcs decreases the amplitude of the current of the short-circuit arc, decreases the angle φ between current and voltage, which decreases the amplitude of the return current and enhances the condition for the arc extinguishing. We analyze the process of arc extinguishing in the three-phase circuit. We would like to note that during the extinguishing of the arc in the first extinguishing pole resistance of electric arcs in two other poles deforms the voltage triangle decreasing the coefficients of the scheme from 1.5 to 1.3 according to the experimental data. This allows to decrease the difficulty of the tests for maximum commutation capability. Simultaneously, we consider the necessity of the selection and regulation of the wave parameters (amplitude coefficient and normal mode) of the test circuit according to the standard for test preparation. Taking into account the decrease of the coefficient of the scheme and the real wave parameters will allow to objectively estimate commutation capability and to optimize the parameters pf the contact arc extinguishing system of an automated switch.

The article discusses the main aspects of the organization of energy-saving environmental production systems. The factors affecting the energy efficiency of the production process from the standpoint of logistics, including the processes of storage, storage and transportation of products within an industrial enterprise, are summarized. As a criterion of energy saving in logistics chains, the coefficient of consumption of energy resources spent per unit of production is given. The analysis of the dynamics of fuel and energy costs per unit of output by the types of activities of petrochemical plants of the Republic of Tatarstan was carried out. The specificity of the level of fuel and energy costs by type of activity is shown, depending on the specifics of production and products. The variation of energy consumption data by types of petrochemical production activities for 10 years has been calculated. The prospects for reducing the energy intensity of petrochemical enterprises in the context of the liberalization of the market of electric energy and power are considered. The materials of the study can be used in managing the development of the real sector of the economy, the service sector, both at the enterprise services level and in government structures.

Published: October 2019

One of the quickly developing trends in the optimization of electric power grids is system development of operation and optimization of branch circuits which are based on linear programming problems. One of its categories is traffic problem. The paper discusses the formulation of various types of transport optimization problems used in the design of the most efficient power supply systems in the real sector of economy. The construction of arithmetic models of problems is carried out. Their optimality criterion is cost minimization for the design of electrical network diagrams consisting of power lines connecting sources and consumers. Examples of designing optimization power layout in mathematical problems considering the transmission capacity of power lines is given. The paper also touches upon a mathematical problem considering possible transit of capacities. The task is to build a mathematical model and solve problems that ensure minimization of process losses and losses of power when designing electrical networks. The results of solving problems are presented in the form of power supply circuits corresponding to the most optimal linking of source and consumer nodes. The work is of a scientific and practical significance as it considers the problem of optimizing economic costs when designing electric power network schemes. Moreover it is based on a qualitatively different level of use of the traffic problem algorithm. The algorithm for solving the minimization problem obtained in this paper allows developing the necessary computing operations as well as quickly obtaining the results of solving the cost optimization problem in the designed electric power network.

Published: October 2019

Nanocluster structures can be easily modified in necessary direction and by controlled way in femtonanophotonics experiments. The variation of the key topology parameters can result in new type of the quantum correlation states/size effect for charged particles.

In our earlier experiments we studied laser-induced topological nanoclusters structures of different types in thin films with unique phenomena in electrophysics and optics (see [1-3]). A simple 2-steps mechanism for enhancement of quantum behavior (e.g. in electroconductivity) exists for different conditions. First, when inelastic length linelastic > acluster we have no incoherent electron-phonon (e-ph) scattering, i.e. the coherent process takes place. Second, when de Broglie wave length λdB ≡ ℓcoh < Λ, (acluster – cluster size , Λ – spatial period of nanoparticle distribution) the coherent tunneling without loss occurs, and a long-range order with interference of the states takes place in the medium due to lattice structure.

Variability of pikeperch Sander lucioperca (L. 1758) cohorts in early life history
Authors: Blabolil Petr , Čech Martin , Jůza Tomáš , Peterka Jiří
Published: October 2019

Year to year fluctuations in 0+ fish cohort strength are a common phenomenon. Many factors can affect cohort strength during the fish's early life period. In this study, development of a 0+ pikeperch Sander lucioperca cohort in the pelagic zone was studied by trawling for 50 days from first larvae hatching, in two consecutive years. In 2007, an abundant S. lucioperca cohort collapsed suddenly soon after hatching. After the incident, slow-growing S. lucioperca prevailed in the catch. In 2008, the catch gradually increased during the whole study period because of prolonged hatching. Environmental factors differed mainly in a slower temperature increase, higher water level and higher zooplankton abundance in 2008 compared to 2007. Our study revealed that a strong 0+ S. lucioperca cohort at the time of hatching might not result in a strong S. lucioperca cohort in general.
Long-time behaviour of the approximate solution to quasi-convolution Volterra equations
Authors: Messina Eleonora , Vecchio Antonia
Published: October 2019

The integral representation of some biological phenomena consists in Volterra equations whose kernels involve a convolution term plus a non convolution one. Some significative applications arise in linearised models of cell migration and collective motion, as described in Di Costanzoet al.(Discrete Contin. Dyn. Syst. Ser. B25(2020) 443–472), Etchegarayet al.(Integral Methods in Science and Engineering (2015)), Grecet al.(J. Theor. Biol.452(2018) 35–46) where the asymptotic behaviour of the analytical solution has been extensively investigated. Here we consider this type of problems from a numerical point of view and we study the asymptotic dynamics of numerical approximations by linear multistep methods. Through a suitable reformulation of the equation, we collect all the non convolution parts of the kernel into ageneralized forcing function,and we transform the problem into a convolution one. This allows us to exploit the theory developed in Lubich (IMA J. Numer. Anal.3(1983) 439–465) and based on discrete variants of Paley–Wiener theorem. The main effort consists in the numerical treatment of the generalized forcing term, which will be analysed under suitable assumptions. Furthermore, in cases of interest, we connect the results to the behaviour of the analytical solution.
Cross-cultural communication during the lend-lease supplies via the Arctic route
Authors: Aleksandrova Elena , Kokanova Elena
Published: October 2019

The article presents the overview of the ways in which cross-cultural communication was carried out during the lend-lease supplies via the Arctic convoys. It reflects on the importance of non-professional translation and cross-cultural mediation in such spheres as medicine, hospitality, transport, customs, etc. The skills of a professional translator are viewed in contrast to those necessary for successful linguistic mediation. The authors emphasise the role of international seamen's clubs in the establishment of contacts between the represantatives of different nationalites. Much of the information provided in the article has never been published before as it was obtained in the state archives of Murmansk and Arkhangelsk, some of which have been open for research in recent years. A number of documents concerning details of cross-cultural mediation during the period of the Arctic convoys were lost or destroyed during the Great Patriotic War, so some information can be obtained only from the participants of the events of that period who are not numerous nowadays.

The paper discusses the main stages of investigation into the dialectological situation in the South of Russia, with special attention being given to the studies of territories close to the Republic of Crimea. This paper presents findings from a field study of the Russian language functioning in an isolated area. We investigate speech of the people living in Greater Sevastopol to identify peculiar features in phonetics, word building, morphology and syntax. Our respondents are both natives and migrants from various regions. The regiolect of Sevastopol is analysed in terms of dialect bases and their correlation, time of migration. Our results show positive relationship between the respondents linguistic and biographic background. The speech of the respondents exhibits a high degree of similarity with the Russian literary language, and demonstrates features of the closely related Ukrainian language. The influence of Ukrainian is more pronounced at the phonetic level and less evident at the lexical level.
Political discourse and the study of parliamentary communication: a comparative analysis
Authors: Konstantinova Anna , Anufrienko Svetlana , Abazalieva Madina , Gevorgyan Arevik , Soloveva Elena
Published: October 2019

The article is devoted to an analytical review of the main areas of theoretical and applied research of parliamentary communication, among which a special attention is given to the theory of political discourse and political linguistics. The prospects for a comparative study of public parliamentary communication are outlined as oneof the comparatively not studied components of political discourse. Today parliamentary discourse, being one of the components of political discourse, is the subject and object of several humanitarian disciplines. The main system-forming factor of parliamentary discourse is its institutionality, which determines both the form and the content of parliamentary communication. The development of parliamentary communication as a democratic form of exercising state power is influenced by historical, social and cultural progress of mankind as a whole, and the specifics of achieving this progress in separate countries. Despite the existence of a universal democratic framework that determines the status of parliament as a social institution in different countries, its activities have national and cultural specifics. Comparison and identification of universal and national-cultural-specific language features of the parliamentary discourse in different countries are the urgent tasks for political linguistics to fulfill.

Dependencies in political studies (non-linearity and typical methodological errors)
Authors: Basimov Mikhail
Published: October 2019

The article raises the question of studying the statistical dependencies in a sociological research. Most sociologists, if they study cause and effect relations, offer interpretations of only linear relations and linear models based on their data. However, the problem arises not only with respect to the fact that sociologists interpreting any linear dependencies ignore a large number of simple non-linear relations (type 1 errors) often without understanding the essence of the issue. In the last 20-25 years, they often study processes not so simple to describe them by means of linear models. And sociologists go (consciously or not) along the way when weak linear relations (not strong ones are detected), referring to the hypothesis of zero correlation coefficient (saving stars SPSS), began to be presented as “significant” and tacitly understood as sufficiently strong correlations of a scientific interest for interpretation of cause and effect relations.But there is an even more significant error (type 2 errors), when they fail to notice not only the simplest non-linear dependencies, but strong simple non-linear dependencies between the parameters that provide their linear approximations with a weak correlation, and even a very weak correlation (0.11-0.3), which completely distorts the real picture of the phenomenon or process under study. It turns out to be scientific knowledge that does not correspond to reality, which contributes to the parallel development of philosophical (qualitative) analysis of social processes, based mainly on an intuitive understanding of social problems, the emergence of contradictions between the approaches. The article deals with some individual dependencies and their interpretation according to the results of the study of political preferences of young people, demonstrating the type 1 and 2 errors.

Authors: Sychugova L.P. , Belozerova A.V. , Lepikhova L.Y. , Akinshina N.V. , Sukhanova Y.S.
Published: October 2019

The authors analyzed techniques of formation of a conceptual system on the synergistic basis of language and speech learning using authors’ cognitive dictionaries. Synergetic dictionaries are created taking into account: 1) student’s perception of randomly perceived facts; 2) consolidation and bifurcation in the minds of cumulative images of the world by verbal and non-verbal means; 3) systematization, streamlining of information obtained through mental actions. The authors conclude that cognitive information verbalized in dictionaries is represented by syntagmas; predicates are a basis of sentence structures; the object prediction is one of the most important stages of the mechanism of translating internal speech into external one. Expansion of the entire cognitive base, including extralinguistic and linguistic components, contributes to mental activities of the speaker.
Fundamentals of metatheoretical understanding of nature based on comprehensive reflection of discourse
Authors: Bredikhin Sergey N. , Marchenko Tatiana V. , Pelevina Nataliia A. , Pelevina Iuliia I.
Published: October 2019

The study provides rationale for meta-theoretical interpretation of a special type of a literary text – the one based on ultimate reflexion. The analysis rests on “camp prose” works characterized by a significant degree of abstraction on the part of the subject of narration and the possibility of contaminating the objective reality phenomena and the ones of personal reflexive reality within the framework of an “objective” observer description. The authors specify the meta-language of the first level abstraction and the peculiarities of constructing the analyzed type of text as a certain acting scheme for both the literary text producer and the recipient. The proposed scheme incorporates a peculiar cognitive experience (featuring creativity, abstraction, intuition and reflexivity) and a new phenomenological reflexion that imply a new way of realizing different types of experience within the scope of reflexive reality. The texts based on ultimate reflexion are defined as verbal-psycho-emotive entities that can trigger a certain state of consciousness in the process of reading and objectify different sense overtones implied by the author.

According to our previous research no attempt was made to find a multiple regression model, and consequently a correlation between the personality trait of an introvert/extrovert, individual motivation and an approach to Russian language L2. After a general review of the literature, we mainly concerned English as a foreign language (ESL). A research was made through a survey of Italian students learning Russian L2 outside the language environment in Italy. Starting from their answers we made a suitable score system, thanks to which we made a distribution, graphical and descriptive function for all the three variables. Finally a multiple regression model is provided to make reconciliation among the variables with statistical estimators of reliability.

The article analyzes directions of development of the international legal mechanism for regulating environmental migration. Two directions were described. The first one involves the extension of the 1951 UN Convention on the Legal Status of Refugees to environmental migrants who have left their permanent places of residence due to an environmental degradation caused by natural or man-made disasters or negative impacts of industrial and economic activities. The second way to create an international legal mechanism for regulating environmental migration and protecting environmental migrants is to develop and adopt a new international agreement governing actions of the international community aimed to protect environmental migrants. The analysis allows for the conclusion that the first direction seems to be the most optimal due to the similar status of asylum seekers and people who have left their places of permanent residence as a result of natural disasters or industrial accidents, environmental and climatic conditions.

The aim of the programme is to devise a commercial model of distance teaching foreign languages that will secure an effective and efficient learning. Successful implementation of about twenty educational programmes of distance learning at MSLU has proved the effectiveness of management and the important role of information gathering with the aim of further expertise. For that purpose special software has been developed. Then some statistic data are given, proving the relevance of courses in different languages, monthly fluctuation of agreement making, the relevance of different types of courses, the relative percentage of students with more than one agreement ect. The results give reasons to believe that in terms of development prospects the major focus in the near future will be placed on increasing the number of taught languages and expanding the variety of educational programmes (with an important step being launching a programme of Russian as a foreign language), upgrading software products with a view to improving distant learning management.

This paper considers the issue of the characteristics of everyday knowledge categories verbalization in professional discourse. On the basis of language fragments, objectifying ideas about the cognitive situation, through frame analysis, surface realizations of significant cognitive categories are investigated, among which are the subject of cognition, the object, the cognitive action, the instrument, the result, space and time. The named semantic nodes form the categorical structure of the frame behind the language fragment. The analysis demonstrates the compatibility of everyday and scientific knowledge division by a speaker; still, it illustrates the specificity of the language expression of frame nodes within the framework of professional discourse.
