Evolution of the Business Models of Russian Construction Companies Digitalization of the Industry
Authors: Cheremisina Tatyana P.
Published: June 2019

Development of the first business models of companies and the sectoral business system of the construction sector in Russia began 10 years after the country’s transition to market economy and was of evolutionary nature. The purpose of the study is to identify the relations between business models of large construction companies and their ability to adopt and apply digital technologies and non-technological innovations. Today, only the largest construction and development companies are capable of purposefully shaping and developing their business models. The share of such companies in Russia is less than 1 %, but their role in the development of the industry is large. Most companies are listed in national and regional ratings, which opens access to the information about their history and development, geography of presence, strategies, experience in overcoming crises, etc. The head offices of these companies are mainly located in Moscow and St. Petersburg, and sometimes in million-plus cities. Research methodology included compilation of a non-representative sample of 50 construction and development companies, identification of four types of business models and analysis of the models on the basis of the collected information. In the construction industry of Russia, business models of large companies evolve from incomplete to complete construction cycle, then to complete development cycle with and without the building contractor function. A significant share of development companies retains the building contractor functions, and it is a distinctive feature of their activity in Russia associated with the high uncertainty of economy. Complete cycle developers show great interest in digital technologies and organizational innovations, but their inclination to digital technologies reduces interest in non-technological innovations and vice versa. The business model of the complete construction cycle gives the companies a weaker impetus for innovation
‘Radioenseñanza’ an educational experience for adults through radio in Huelva at the end of Francoism
Authors: Hermosín-Mojeda Manuel Jesús
Published: June 2019

‘Radioenseñanza’ was an interesting experience carried out in the province of Huelva (Spain) over two academic years before the 1970 education law (Ley General de Educación). It was organised by the new broadcasting company ‘Radio Popular’ in collaboration with the local administration of the Ministry of Education at the end of Francoism. This activity was developed with didactic resources published by ‘Radio ECCA’, which had started broadcasting for educational purposes on the Canary Islands with the Jesuit priest Francisco Villén Lucena a few years before in 1965.Despite its benefits for the population, this fruitful experience had to finish early just two years after it started, due to some disagreements (mainly of an economic nature) between the broadcasting company and the education administration.The aim of this article is to outline the origins, dissemination and scope of this brief experience in the province of Huelva.
Challenges and Prospects of Evaluation of Programs in Public Finance Management in Georgia
Authors: Oboladze D. , Otinashvili R.
Published: June 2019

The establishment of a program assessment mechanism in the public sector of Georgia is an important element for supporting the ongoing public finance management reform and improving the budgeting process as well as enhancing the budget planning stage and ensuring the efficient, productive and prudent management of budgetary means. The present paper discusses the problem of the absence of a program assessment mechanism in the public sector, reviews alternative solutions to the problem and, by applying a cost-effective method, analyzes the best alternative. This best alternative envisages the establishment of a centralized structural unit at the Ministry of Finance which will be responsible for the assessment of the programs/subprograms of ministries/budgetary organizations. The concluding part of the policy paper offers those measures and reforms in the form of recommendations which must be undertaken for the successful implementation of the best alternative.
Evolución y dinámica geomorfológica actual del río Ebro en la Reserva Natural Dirigida de los Sotos y Galachos (Zaragoza)
Authors: Najes Pérez Laura , Ollero Ojeda Alfredo , Sánchez Fabre Miguel
Published: June 2019

El río Ebro en la Reserva Natural Dirigida de los Sotos y Galachos del Ebro ha generado cambios geomorfológicos notables debido a su propia funcionalidad, destacando por su dinámica fluvial muy activa en el contexto general del Ebro medio. Las imágenes aéreas de los años 1927, 1956, 1998, 2006 y 2015 han permitido cuantificar e interpretar dichos cambios. La comparación evolutiva de los cauces activos, el cálculo de superficies movilizadas y las medidas de desplazamiento de los vértices de meandro muestran una reducción progresiva en la actividad fluvial a lo largo de los últimos 90 años, debido a factores fundamentalmente antrópicos. Este hecho también se refleja en los datos obtenidos para usos de suelo. No obstante, el análisis detallado de la ortofoto de 2015 muestra la pervivencia de cierto dinamismo, asociado fundamentalmente a la crecida de ese mismo año, pero indicador también de la capacidad de trabajo geomorfológico del río Ebro en este tramo. El proceso de reducción o limitación de la dinámica parece haberse frenado en la actualidad, lo cual permitiría con las medidas de restauración fluvial adecuadas recuperar, al menos parcialmente, la movilidad geomorfológica del río.
EUROPEAN DIMENSION IN QUALIFICATIONS FOR THE TOURIST SECTOR AS AN INSTITUTION FOR RUSSIAN DESTINATIONS DEVELOPMENT
Authors: Ilkevich S. V. , Prikhodko L. V. , Smith N. L.
Published: June 2019

Adaptation of the best practices of the extensive and nationally specific European experience in the field of measurement of qualifications becomes particularly appropriate as there is some delay in the development of Russian scientific, practical and methodological approaches to the national qualifications framework. At the same time, the shortage of highly qualified personnel in the fast-growing tourist sector is becoming chronic, and the results of creating tourist clusters are ambiguous, with a large share of failures in the implementation of master plans for territorial tourism development. In this regard, the acceleration of the development of a structured measurement of qualifications in the form of a national qualifications framework becomes demanded not only to achieve greater maturity and effectiveness of the Russian educational and professional systems in the tourism sector, but also as a common institution for the strategic development of Russian destinations in training areas, technologies, competencies and the innovation potential of the tourism and hospitality industry. The projects of the European Commission ERASMUS+ are one of the effective network channels for the development of national and international expertise in structural measures to optimize educational systems, and in particular, to compare and develop systems, matrices frameworks for qualifications. The article represents an attempt to highlight how the implementation of a structured project in the field of qualifications can correspond both to general progressive trends in the evolution of educational systems and to the overall objectives of territorial tourist development. As a conceptual result, the authors identify six mid-term and six long-term effects of the developments of a national qualifications framework that directly and indirectly provide beneficial outcomes within the development of Russian destinations through improving the focus of retraining and advanced training programs, enhancing lifelong learning, promoting labor mobility in the tourism sector, successful validation of informal education, wider circulation of partial and intermediate qualifications in the tourism and hospitality industry. Adjacent to this issue is the problem of the relationship between the development of educational clusters in the tourism sector and the national qualifications framework, on the one hand, and tourism clusters, on the other, the consideration of which is also presented in this article.
Collective memories and cultural trauma of different generational groups
Authors: Baranova V.A. , Dontsov A.I.
Published: June 2019

The article theoretically substantiated the approach to the study of cultural trauma through the analysis of memories of generations, characterized by signs of injury. Scientific tasks involved the identification of events that construct two generations of memories of a particular historical period and an analysis of how these events can be characterized as a cultural trauma. The study used survey methods and in-depth interviews. The sample was 83 respondents. The content of collective memories testifies to the marked signs of cultural trauma, which is associated with a certain historical period: for the generation of 1961—1975. These are the events of the late 80s — early 90s, which determine the beginning of changes in the political and economic system: perestroika, the collapse of the USSR; for the generation of “children of war”, this event is the Great Patriotic War and the postwar period. Theoretical analysis and empirical research suggest that cultural trauma is reflected in the memories of generations. The study also recorded post-memory processes, — the attitude of the younger generation to the traumatic events of the twentieth century, which are beyond personal experience.

Authors: Volkova N.V. , Chiker V.A. , Pochebut L.G.
Published: June 2019

The aim of this article is to consider the consolidation of social capital in two Russian state organizations under the context of different generational cohorts, namely, Baby Boomers, Generation X and Y, and the features of their organizational behavior. Consolidation of social capital is based on the integrated semantic area that could include the estimation of organizational culture, employees’ commitment to company goals and values as well as strong organizational identification. Extensively, consolidation of social capital is determined by organizational, generational and subcultural peculiarities of staff. Altogether, 250 employees participated in this study and filled in three questionnaires to estimate organizational culture, commitment and four dimensions of identification. The data collected in two sample groups (90 and 160 people) in St. Petersburg and Petrozavodsk respectively demonstrated the significant differences among generational cohorts both in the organization and between them. The most hardships in the consolidation of social capital undergo generation X whose formative years had been within Perestroika span and strong social changes in Russia. All that is reflected at their level of organizational identification and contradictions while perceiving current and preferred organizational cultures.

Authors: Boev I. A. , Godovalov A. P. , Shtraube G. I. , Antakov G. I.
Published: June 2019

Aim. To study the characteristic features of long-term facial phlegmon morbidity in Perm Krai with assessment of the efficiency of infusion therapy using indices of endogenous intoxication expression.

Materials and methods. Manifestations of epidemic process of facial phlegmons were studied on the basis of a detailed retrospective analysis of sickness rate among the inhabitants of Perm Krai for the period of 2011–2016. In group 1, all patients besides standard therapy, underwent infusion therapy, and in group 2 – standard therapy alone. Prior to and after the therapy, peripheral blood cellular composition was assessed, and leukocytic indices of intoxication were calculated.

Results. A long-term dynamics of facial phlegmon morbidity was established to show the irregularity of process expression according to years. Growth of the quantity of patients is provided by increase in the number of cases with complicated forms. Besides, males play a significant role in formation of sickness rate: the chances for the development of phlegmon among them are 1.49 times higher than in females. In the age structure of morbidity, prevail persons aged 21–30 and 31–50. A half of patients have endogenous intoxication. The course of infusion therapy essentially reduces the expression of endogenous intoxication.

Conclusions. There is observed a tendency to growth of facial phlegmon morbidity that is probably connected with changes in etiological structure of pathogenic agents as well as with formation of pathosymbiosis of some opportunistic pathogenic microorganisms. As a rule, phlegmon is being developed against the background of endogenous intoxication, conditioned by both microbial metabolites and tissue destruction products. The efficiency of correction of endogenous intoxication using infusion therapy is shown.

Authors: Bykova L. P. , Trapeznikov Ya. P. , Godovalov A. P.
Published: June 2019

Aim.To assess the growth properties and formation of E. сoli biofilms with different concentrations of cholesterol available.

Materials and methods. E. coli strains were cultivated in the meat-peptone broth with cholesterol added in the concentration of 3, 5, 7 and 9 mmol/l as well as in the nutrient medium without cholesterol. The growth parameters and cholesterol concentration in the samples prior to and after cultivating microorganisms and the effect of cholesterol on biofilm-forming activity of E. coli was determined.

Results. Cholesterol was shown to have no bactericidal effect on E. coli, however, it is able to change the duration of growth phases of the strains that is, possibly, caused by adaptation to the presence of cholesterol and switching of metabolic pathways. Cholesterol has a stimulating effect on accumulation of biomass by the test-strain and its biofilm-forming activity.

Conclusions. In the study performed, the ability of E. coli to metabolize human cholesterol was shown.

Published: June 2019

Purpose:The study was carried out to investigate the expectations of liver
transplantation candidates and their relatives concerning transplantation and
the difficulties they experience.Materials and Methods:This descriptive
and single-center study was performed in the Transplantation Polyclinic of a
public hospital in Ankara. The sample consisted of 170 liver transplantation
candidates and 170 patient relatives. Data were collected through face-to-face
interviews with participants. Percentage, average, chi-square, and Fisher’s
exact chi-square tests were used to evaluate the data.Results:This study reveals that the most important expectation of liver
transplantation candidates during the waiting period is “a transplant operation
with successful results” (70.0%), whereas liver transplantation patients’
relatives are primarily concerned with the expectation that their sick relative
will “regain her or his health”(80.0%).Almost all (97.1%) of the patients had
physical problems,and the majority of them(87.1%) struggled with activities of
daily living and experienced psychological (85.3%) and socio-economic problems (81.8%).Patients’
relatives also had problems associated with activities of daily living (80.6%)
and experienced psychological (81.8%) and socio-economic (73.5%) difficulties.

Conclusion:The results of this study confirm that liver
transplantation candidates and their relatives experience many difficulties
that impact their activities of daily living, as well as psychological and
socio-economic problems.In order to provide relief from these difficulties, liver
transplantation candidates and their relatives should be given training and
counseling.

Published: June 2019

Purpose: The objective of this study was to evaluate the knowledge and behaviours of the first year students of a medical school on emergency contraception in Nicosia, Cyprus.Materials and Methods: The data of this cross-sectional study were collected in February 2016 by a questionnaire administered under observation. Of the 467 first year students of the Medical School, 418 responded to the questionnaire, with a response rate of 89.5%.Results: Students were from 24 countries but the majority were from Turkey (58.0%), Nigeria (11.8%) and Northern Cyprus (8.2%). The correct knowledge of definition of emergency contraception (EC) level was 57.6% and 57.2% knew the purpose. There was a significant difference regarding knowledge of correct definitions of emergency contraception and emergency contraception pills among continental groups, with lowest level of knowledge for Asian country members. Of the total, only 33.9% of the participants had correct knowledge of effective timing for EC and 14.2% of the definition of emergency contraception pills. Excluding those who stated having no knowledge of emergency contraceptives and effective timing for EC, only 36.7% -for each concept- of the remaining participants claiming to be informed about these concepts, defined them correctly. The use of contraceptive methods was 49.5% and emergency contraception 23.1% among sexually active participants.Conclusion: The knowledge level and behaviours of medical students on emergency contraception were insufficient. Emergency contraception education should be provided for all first year medical students, as well as other university beginners.

Using: Study of Multiculturalism and Identity Politics on Local Islam
Authors: Halim Abdul
Published: June 2019

This research reviews multiculturalism and identity politics with the object of Using Islam. Using ethnic is a native of Banyuwangi which is predominantly Muslim. The existence of the Using community in addition to describing the spirit of multiculturalism also reflects the spirit of identity politics. Using people live in Java and speak Old Javanese, but they tend to identify themselves as Using ethnicity rather than Javanese. They also refer to the language as Using language, not Javanese. Becoming its own ethnicity makes the Using community have a number of distinctive cultural traditions and systems, including Islamic practices. Islamic values are acculturated with Using's local values and form a unique religious culture system. Socio-anthropologically, the persistence of Using's ethnic attitude is a reflection of identity politics that arises because of past historical experiences that were colonized by other powers, including the Islamic Mataram kingdom.
The Toll-like Receptor 2 (TLR2)-related Immunopathological Responses in the Multiple Sclerosis and Experimental Autoimmune Encephalomyelitis
Authors: Jafarzadeh Abdollah , Nemati Maryam , Khorramdelazad Hossain , Mirshafiey Abbas
Published: June 2019

Toll-like receptors (TLRs) play principle roles in recognition of autologous components which have been pointed as the danger-associated molecular patterns (DAMP) and microbial components which are identified as pathogen associated molecular patterns (PAMP).The infiltration of various inflammatory cells such as dendritic cells, lymphocytes (CD4+ T, CD8+ T as well as B cells), monocytes and macrophages occur into the central nervous sys­tem (CNS) during multiple sclerosis (MS) and its animal model named experimental autoimmune encephalomyelitis (EAE). The infiltrated leukocytes and residential cells of the CNS express several TLRs (especially TLR2) and their expression are elevated in MS and EAE. TLR2 recognizes a large variety DAMP and PAMP molecules due to its ability to create heterodimers with TLR1, TLR6 and probably TLR10. A wide spectrum of  DAMP molecules, including heat shock protein 60 (HSP60), HSP70, high mobility group box 1 (HMGB1), β-defensin 3, surfactant protein A and D, eosinophil-derived neurotoxin, gangliosides, serum amyloid A, hyaluronic acid and biglycan are identified by TLR2, whose their expression is increased in MS patients. TLR2 may contribute in the development of MS and EAE diseases through the reinforcement of Th1/Th17 cell-related responses, downregulation of regulatory T cells, induction of IL-17+ γδ T cells, inhibition of oligodendrocyte maturation, induction of poly ADP-ribose polymerase-1 (PARP-1)-dependent pathway in microglia, macrophages and astrocytes and inhibition of type I interferons expression. The contribution of TLR2-related immunopathological responses in the MS and EAE pathogenesis and its possible targeting as promising therapeutic potentials are considered in this review.

Published: June 2019

Vascular endothelial growth factor receptor 2 (VEGFR-2) is known as one of the important antigens playing a vital role in angiogenesis. In this study, phage display technology (PDT) was used to produce a single-chain variable fragment (scFv) antibody against a region of the domain 3 in VEGFR-2 called kinase insert domain receptor 3 (KDR3).
After designing the KDR3 peptide and biopanning, a colony was chosen for scFv antibody expression. Following expression and purification; western blotting, dot blotting and immunofluorescence (IF) were used to evaluate the antibody function. Surface plasmon resonance (SPR) was also employed to measure affinity of produced antibody.
Once a colony was selected and transferred to the expression host, the scFv antibody was expressed in the expected range of 28 kDa. Using a designed chromatography column, antibody purification was found to be about 95%.
In this study, a novel scFv with the capability of binding to KDR3 was isolated and purified and its intracellular function was investigated and verified.

CONTRIBUIÇÕES DA SOCIOLOGIA DAS PROFISSÕES PARA A ANÁLISE DAS PROFISSÕES DE ARQUIVISTA E MUSEÓLOGO NO BRASIL
Authors: Alves Thiara dos Santos
Published: June 2019

Este artigo consiste em uma reflexão teórica, realizada a partir de levantamento bibliográfico, sobre a contribuição da Sociologia das Profissões para a análise das profissões de Arquivista e Museólogo no Brasil. Buscou-se desenvolver, sempre que possível convergindo para a realidade dos Arquivistas e dos Museólogos, os conteúdos da Sociologia das Profissões sobre a centralidade do conhecimento científico e o papel do Estado nas determinações profissionais e também sobre as profissões na sociedade democrática e a organização profissional. Este trabalho demonstrou que o diploma de nível superior é um critério determinante para distinguir os conceitos de profissão e ocupação e que o Estado exerce um papel relevante nas determinações profissionais. Destacou-se que cada grupo profissional possui um campo de atividade exclusivo e um campo residual de atuação profissional, no qual as profissões concorrem pelo mercado de trabalho. O controle legal sobre as profissões de Arquivistas e Museólogos, por meio da formação universitária e da regulamentação profissional, garante-lhes o exercício jurisdicional sobre certas atividades exclusivas; no entanto, não os exime da investida de alguns grupos, como dos Historiadores, pois a disputa é inerente ao campo das profissões. Na reflexão teórica aqui apresentada, evidenciou-se que as organizações profissionais são as responsáveis pela definição de laços de confiança púbica nas profissões e entre os profissionais. O campo museológico está melhor representado pelo Conselho Federal de Museologia e pelos Conselhos Regionais de Museologia. Ao passo que as associações estaduais é o tipo de organização profissional que se sobressai no campo arquivístico.

Memory construction of the local space: analysis of mnemonic online messages on Shabolovka district (Moscow)
Authors: Rud Daria
Published: June 2019

The article is devoted to narrative recollections, published in social media. The author analyzed messages about the district Shabolovskaya / Tulskaya (in Moscow) in 2018. Analysis was performed using concepts of memory scale and mnemonic media. The concept of scale, usually used in a topographical sense, is modifed and applied to the temporal depth. Mnemonic media allows tracing memories with diﬀerent criteria of memory validity and have a variety of functions: identity, imagination, knowledge transfer. Topics of Great Purge and avant-garde are isolated subjects of narratives, not intersecting with other topics. Narrative triggers of “mememory”, such as old city photographs, were identifed to designate the positions of a unifed identity, e.g. owners of childhood memories in a Soviet city. Typical features of narratives referring to diﬀerent places were analyzed. Work can be attributed to the felds of post-socialist research, approbation of memory research methodology, analysis of narrative recollections in social media, local memory investigation.
Between Nostalgia and Retrotopia
Authors: Starovoytenko Andrey
Published: June 2019

The notion of nostalgia has been used across various social sciences and humanities, having been rethought many times and acquiring many conceptual configurations. These configurations are not always easy to integrate with each other. Yet a number of new approaches have emerged that make it possible to look upon a person’s (a collective’s, a society’s) attitude to their pass diﬀerently. The brightest of them all is the theory of retrotopia as provided by Zygmunt Bauman in his last book. Thus the article has two goals. First, various approaches to theories of nostalgia are observed. Second, it is an attempt to fnd out how Bauman’s retrotopia could help to think more clearly about the problems traditionally discussed within theories of nostalgia.

Authors: Marykyn Aleksander , Myroshenko Vasiliy
Published: June 2019

Objective: To analyze transient processes when activating reactive power compensation unit with variable inductance and load bounce in electric traction alternating current network. To determine reactive power control range for possible structural variations of a unit. To choose the most power efficient variant of mutual connection of controlled reactor and capacitor bank with uncontrolled capacity in reactive power compensation unit. To make a conclusion, concerning feedback device application in control system. Methods: Connection diagrams of a unit to an alternating current monophase network. Mutual connection diagrams of controlled reactor and capacitor bank were chosen. Structural variations’ control range analysis of reactive power compensation unit was conducted. In MATLAB Simulink software package, simulation of different bucking out system circuitry was fulfilled. Simulation of compensation unit functioning was carried out for one variant with load bounce in electric traction. Results: It was established that, in case of series connection of controlled reactor and capacitor bank, control range may comprise no more than 15 % of nominal capacity. Starting current of a unit reaches twofold value. Parallel connection makes it possible to control reactive power in a broad band. Starting current in this case reaches fourfold excess of value. It is suggested to use uncontrolled reactor successively with capacitor bank as an additional unit. Such a variant makes it possible to reduce starting current and simultaneously provide filtration of the third current harmonics. Practical importance: A series-parallel variant of compensation unit circuitry seems to be the most perspective for application in electric traction alternating current network.

Published: June 2019

Objective: To obtain technical equipment of infrastructure and terminal capacity relations in order to determine the necessary gridiron of tracks, as well as to assess efficiency and optimization of existing stations’ functioning. Methods: Based on synthesis and analysis of stations’ operation, as well as transport systems’ simulation modeling theory. Results: Parameters, influencing the present and designed terminal capacity, were identified. Cause-and-effect relations of events, resulting in railway machinery being brought in non-serviceable condition, are established. Dynamic system of indices was suggested, allowing for a more precise solution of the following tasks: to identify the necessary and sufficient gridiron of tracks for passing the specified amount of traffic, to assess the most probable amount of traffic at the station and its loading. Criteria of input and output flows of traffic at the station, as well as lay-over and trains' delays were stated, the former make it possible to analyze the suggested technical equipment and station functioning. Practical importance: On the basis of obtained relations it is possible to specify optimum relationship of trains’ lay-over time at station yards, the reserve of gridiron of tracks’ elements time in use and the number of routes being implemented at the station, as well as the necessary gridiron of tracks within the given аmount of train traffic. The results of the research may be applied in designing new railway stations, as well as optimization of station functioning and reconstruction of the existing stations.
Application of virtual glide path for calculation of aircraft deflection at the final stage of landing
Authors: Olevinskaya Tatyana
Published: June 2019

Objective: The development of a calculation method of aircraft guidance parameters (linear and angular deflection from a synthetic glide path) by means of global satellite navigation system signals. As opposed to the existing methods, it is suggested to use an inclined plane, containing a glide slope line, as a base surface for vertical guidance. Methods: An experimental research was carried out, based on the suggested method of deflections’ calculation, as well as the comparison of results was fulfilled with identification of guidance parameters’ data by means of the existing methods. Results: It is shown that the results of calculating deflections from a glide path by means of the developed method and those methods, which are currently applied in transport planes landing, are practically the same. Practical importance: Application of the given method of calculating aircraft deflections from a glide path will make it possible to simplify significantly the deployment of the ground segment of landing system in airports, which in its turn will give the opportunity to equip regional airdromes of the third and the forth class, which are currently equipped with imprecise approach systems (compass locators or, the so-called, VOR) or have no radio-navigation aids, with satellite systems of precision approach. Satellite landing system implementation will allow aircraft crews, provided with proper airborne equipment, to pass, in case of need, from a contact fly to an instrumental fly conducted under flight rules. The above mentioned will reduce airdromes meteorological minimum, which in its turn will cause the decrease in the number of non-flying days and increase the efficiency of airdromes and fleet exploitation. One more advantage of satellite landing system application is the fact that it allows students to work out the procedure of approach on instrument landing system.

Objective: To define the reasons, that prevent the implementation of electrical brake for multiple unit rolling stock (MVPS) with asynchronous traction drive as an automatic brake (emergency brakes). To find the method for eliminating of found reasons. To determine, using mathematical simulation, the time indexes of traction drive readiness to the electrical braking in case of no voltage in catenary system. Methods: Mathematical model of traction drive is built in Matlab Simulink software. By using this model the empirical relations of the time from the moment of command input, made by the control system, to start an emergency braking, to the moment of charging of input capacitors to nominal voltage (in case of no voltage in catenary system) from the train speed and equivalent resistance of stator circuit were obtained. Results: The problems, preventing the implementation of electrical brake for MVPS as an automatic brakes, are examined. The methods of solving these problems are suggested. By using the mathematical model the principal possibility of suggested methods is presented, as well as the estimation of the time of traction drive preparing for readiness for braking, depending on the train speed and equivalent resistance of stator circuit. Also, the engineering solutions, are found, that allow to implement the electrical brake for multiple unit rolling stock as an automatic one. Practical importance: Electrical for brake multiple unit rolling stock with asynchronous traction drive has several benefits in comparison with the pneumatic brake. It provides smaller braking distance, not influenced by low temperatures and provides better resistance for sliding and skidding. Implementation of electrical brakes for multiple unit rolling stock in the function of automatic brake will positively influence on the safety of operation and will allow to increase the operating speed of multiple unit rolling stock.
