Description
The article is devoted to the development of high-tech metal-working industry, as well as to the use of unmanned technology. We recommended measures to improve the accuracy and quality of manufacturing of complex and large workpieces weighing up to 100 tons. To date, the technical level of many economy sectors is largely determined by the level of the production means. Based on the engineering development there is an overall automation and mechanization of production and industry processes, construction, agriculture, transport and other industries. We analyzed forms of slide sections, of errors affecting the accuracy of the workpieces manufacturing. We made simulation of the cutting forces and sliders deformations. Solved measures increase manufacturing accuracy based on multi-purpose machine tool systems of VM series. We held the analysis of the dependence of cutting forces, a slider form on its strain in different types of processing. We obtained a graph of cutting force and precision manufacturing. We defined the optimal shape of the slider cross section to increase the rigidity and reduce the slide deformation in metal cutting

Description
The article presents the criteria for evaluating the integration of researchers in the scientific community, based on an analysis of its citations. It is known, that one of the major components of interscientific communication (communication in the scientific community) is a citation of scientific publications (monographs, articles, etc.). According to the sociological approach, a scientist is a part of society, ie, scientific community; under scientific community we understand scientific mega environment (opposed to research groups of institutions and their structural units). Integration of a researcher to the community has many aspects: on the one hand, it is - the importance of his work to the scientific community, on the other hand, it is - the use of a scientist social mega environment for building for their personal and professional development to improve their research and improve the quality of its results (in the context of the article we will consider the second aspect). Methodological bases of the research: systematic, competence, sociological, and mega-system qualimetric approaches. Methods: modeling, methods of quality control, methods of set theory, relations and graphs. Evaluation (diagnostics) involvement of scientists in the scientific community - is more complicated metrology task than the evaluation of the significance of the results of its research activities. For the authors it is clear that a mature scientist (with a high level of research competence) should intensively use the potential of the social and the cultural science international environment (community) for their personal and professional development, to improve the efficiency of this research activities and the quality of this results. The proposed indicators can be considered as group indicator variables reflecting the level of the behavioral component of the research competence (scientist). Using social media for researcher’s potential – it is necessary, but not sufficient condition for productive research, producing goodquality scientific results. In this situation, negative prognosis is more significant: poor use of social media for researcher’s potential – is a "guarantee" for low productivity of this research activities and the low quality of this results. Only the combination of the highest levels of readiness for research (research competence) with high levels of other competences (as a whole - the social and professional competence, implying the presence of the professional skills of selforganization) can be the factors of successful research

Description
We have illustrated multiple factor analysis of the dynamic friction coefficient of the friction units in tribosystem and tribounits under laboratory conditions. As the tribosystem we had a model band-block brake with regime parameters of the control handle tension of the brake and brake work. By using the method of the mathematical planning of the extreme experiments, we have obtained functional dependence of the dynamic friction coefficient of the variable parameters in the form of a second-order polynomial, which adequately describe the processes under study. As tribounit at the micro- and nanoscale there was the reference change of the dynamic friction coefficient of the pair "Retinax FC-24A – Steel 35HNL" as a function of surface temperature, the values of which correspond to certain laws, based on the rise and fall of the characteristics of the dynamic friction coefficient. We have made the evaluation of the dynamic friction coefficient on the principle of the superposition with the multiple factor analysis of the following parameters: the process of forced cooling and heating; the processes of the polarization and depolarization in the contact patch of the micropoints of friction pairs; the type of the contacts of the micropoints depending on the work function of the electrons and ions from materials; the formation of primary and secondary structures on the surfaces of frictional contact; the destruction and restoration of the pellicles on surfaces, etc. We have analyzed the results of the studies of changes of the dynamic friction coefficient on the macro-, micro- and nanoscale and we have found the basic factors affecting its value

AGAINST THE LIES AND INSINUATIONS OF THE GREAT PATRIOTIC WAR 1941 – 1945
DescriptionThe authors in the article reveal the highlights of the history associated with the prehistory of the Great Patriotic War of 1941 - 1945, its tragical beginning in the first few months and its further course, up to the Great Victory in May of 1945. They dwell on the analysis of the causes of the Second World War and the Great Patriotic War of the Soviet people against Hitler Germany. The authors, in spite of liars and forgers, show who is to blame for their unleashing and clearly indicate that the Second World War was unleashed by Hitler, through and in fact with the blessing of Western powers and especially Britain and France, carried out the policy of "appeasement" the aggressor, and ended the Munich Agreement of 1938. The authors pay special attention to the Treaty of Non-Aggression between Germany and the USSR, signed on August 23, 1939, known as the Molotov - Ribbentrop Pact. They argue that this was a necessary step on the part of the Soviet Union and that this agreement, Stalin was trying to gain time and delay the beginning of the war against Nazi Germany. The authors show that Stalin and the Soviet leadership were perfectly aware of the fact that on 1 September 1939, Hitler attacked Poland and then it would be the USSR. Considering the progress, results and lessons of the Great Patriotic War of 1941-1945, the authors elaborate and criticize the information widespread in Western historiography, as well as, first and foremost, in terms of the Soviet-Russian, lies, slander and all kinds of insinuations about the Great Patriotic war

Description
The reasons for the development of Protestantism in the South of Russia in the late XIX - early XX centuries are discussed in this article. Standpattism is spreading among the population of southern Russia. The ranks of the Protestants were replenished with the social strata associated with the development of capitalist relations in town and village. The emergence and development of Protestantism is an important feature of capitalization and Europeanization of Russia. By the beginning of XX century the Baptists are widely distributed throughout the South of Russia. In the late XIX - early XX century the process of converting from Orthodoxy to Protestantism of Cossacks was observed in the South of Russia. The article also researches Russian Protestantism – the old belief. In 1883 it became possible the old believers' worship. Russian Protestantism gained almost full rights

Description
The article considers problems of the exchange of information between teachers, students and departments of educational institutions. It analyzes the advantages and disadvantages of traditional approaches: email, chat via phone, social networks. The questions of placement of information to large numbers of users were revealed. We also revealed the need to address issues related to the publication of major events, administrative announcements of educational institutions, which are visible to all users, and are assigned to a specific date. We suggested an approach to the publication of the activities of the individual system modules. The article shows a mechanism of mass mailings, providing users the ability to transmit information to two or more recipients and to ensure the exchange of information that is available only to send the recipient, as opposed to the "wall". We found an approach to increase the quality of the educational process, allowing rapid exchange of information between staff, students and departments of educational organization on the example of the system "Social network educational organization." In the approach, it has been proposed to take the ideology of social networking and project it on the specifics and needs of educational institutions, which will allow rapid exchange between staff, students and divisions (departments) educational organization. The study analyzed data on the age of users of the system over a period of 30 days

Description
The article considers questions of workflow in the educational organization. It revealed the need to process everyday documents, which exchange does not have the character of strict accountability, but they are also crucial to the implementation of the work in the educational organization. The exchange of such documents is different from the traditional workflow, primarily, it is the speed of document creation and sharing them. We identified other requirements and limitations to the daily workflow of documents. The study proposed to divide document on direct and indirect. The article formulates basic differences between direct and indirect document. It also analyzes the advantages and disadvantages of traditional approaches based on file servers and cloud data storage. We list problems of implementation of the account running errands. We have offered the structure of the order in the approach. The study shows an approach to increase the quality of the educational process based on the implementation of the indirect workflow through the use of centralized WEB system for the exchange of files, documents, accounting running errands, organizing indirect document. The proposed approach takes responsibility for storage of files from the technical support department of educational organizations can work with the system with mobile and desktop devices

01.00.00 Physical-mathematical sciences
DescriptionThis article describes a mathematical model of transport of salt ions in a cell with a rotating disk cation exchange membrane at transcendent current regimes, taking into account electroconvection. Based on this model, we had a theoretically study of the process of transfer of salt ions and the dependence of the thickness of the diffusion layer from the fall of potential. This article is a continuation of [8] and [9], it conducted a numerical analysis of boundary value problem for a system of equations Nernst-Planck-Poisson and Navier-Stokes equations, modeling the transport of salt ions in a cylindrical cell with a rotating disc cation exchange membrane based on electroconvection. It is shown there is an electroconvection vortex in the center of the membrane disc. The solution flows around this vortex and forms a stagnation zone in front of it. With the increase in the size of the fall of potential, the electroconvective vortex decreases and at some value, the electroconvective vortex disappears. The study was conducted in the 1000 s when the angular velocity of 30 turns in a minute and change of the potential difference of 0.2V to 1.4V with a step 0.1. As a result, in this study it is shown that the thickness of the diffusion layer is practically linearly dependent on the fall of potential. The linear dependence of the thickness of diffusion layer from the fall of potential, in the first approximation, is disturbed by a slight deflection curve, the causes of which are needed to be found by means of extra experiments

TECHNICAL AND ECONOMIC PERFORMANCE OF VM32 MACHINE MULTI-COMPLEX
DescriptionThe article describes problems of economic growth of the Russian Federation, development of high-tech knowledge-intensive manufacturing industries on the basis of a fundamentally new technological order, creation and development of import-substituting production of engineering resources that relate to dual-use technology and are in the most demand by strategic organizations of machinetool, machine-building and military-industrial complexes (aircraft engineering, rocket and space engineering, shipbuilding and power engineering). We proposed some measures to improve the accuracy in the manufacture of complex and large-sized parts with weights up to 100 tons. Precision machining of the workpiece surface is directly dependent on the tooling, quality and quantity of the cutting tool (CT), as during the processing the CT wears and must be replaced. We have described the modernization of multi-machine complex and ways of increasing the accuracy, the change in the kinematics tool supply to increase the number of tools used in the processing. We made calculations of the new chain drive of the tool supply. The proposed modernization of the tools will increase the instrument amount that allows increasing the accuracy of manufacturing products. We have also made calculations of the economic effects of the tool supply modernization

OPTIMIZATION OF WELL PLACEMENT IN WATERFLOOD PROJECT IN "X" FIELD NIGER DELTA, NIGERIA
DescriptionWater flooding used in secondary oil recovery to level up reservoir pressure can be enhanced in order to fit the reservoir conditions with the aim to optimally recover oil. One of the important optimization variables to realize this aim is optimal well placement. Various methods have been suggested for this problem. Among these is direct optimization, although accurate, is difficult due to the number of simulations required. Optimal placement of up to six injection wells was studied at the X field in western Niger Delta of Nigeria. Injection rate and injection time was also optimized and net present value (NPV) of the flooding project was used as the objective function. In this case study, it is shown theoretically and by means of Eclipse 100 that according to the basic elementary reservoir characteristics, optimal oil recovery is strongly dependent on well placement pattern and injection rate. Simulation results show that good sweep efficiency can be achieved with a regular pattern with an optimal well position
