Wormholes and Naked Singularities in Brans-Dicke cosmology

We perform analytical and numerical study of static spherically symmetric solutions in the context of Brans-Dicke-like cosmological model by Elizalde et al. with an exponential potential. In this model the phantom regime arises without the appearance of any ghost degree of freedom due to the specific form of coupling. For the certain parameter ranges the model contains a regular solution which we interpret as a wormhole in an otherwise dS Universe. We put several bounds on the parameter values: $\omega<0 ,\,\, \alpha^2/|\omega|<10^{-5},22.7\lesssim\!\phi_0\!\lesssim25\,$. The numerical solution could mimic the Schwarzschild one, so the original model is consistent with astrophysical and cosmological observational data. However differences between our solution and the Schwarzschild one can be quite large, so black hole candidate observations could probably place further limits on the $\phi_0$ value.Comment: 20 pages, 6 figures, typos & errors correcte

The development of vocational pedagogical education in Russia (organizational and pedagogical aspect)

The relevance of the problem under study is based on the necessity to determine the directions of studying and improving the vocational pedagogical education (the system of training vocational pedagogical teachers) in Russia. The purpose of the article is to identify the periodization of establishment and development of the vocational pedagogical education in Russia depending upon the changes of its organizational and pedagogical foundations that occur under the influence of socio-economic and socio-pedagogical factors. The leading approach to studying this problem is historic-logical one which allows us to identify stages of establishment and development of the vocational pedagogical education based on the qualitative changes of its organization and content that are perceived as a reaction to socio-economic and socio-pedagogical conditions at certain periods of time. Based on the qualitative changes of the organizational and pedagogical foundations of the vocational pedagogical education occurred under the influence of the changes in the society during more than a hundred years’ time, the stages of establishment and development of the vocational education are detailed in this article. It is stated that the main directions of the Russian vocational teachers’ training system development were determined by the requirements imposed upon the system by vocational education and industries. It is shown that the idea of industry-specific vocational and psychological training and training for a worker’s profession is the leading one in elaborating the vocation education development strategy. The article can be useful for academic specialists and practitioners in the sphere of vocational and vocational pedagogical education, candidates for a master’s degree and students of vocational pedagogical universities and faculties. © 2016 Fedorov and Tretyakova

Study of Flotation Isolation of Polyvinyl Acetate

In this paper, the effectiveness of polyacrylamide-based collecting samples for the separation of polyvinyl acetate by flotation method is studied. It is determined that the collectors show maximum efficiency at a concentration of 2 mg/l. Maximum efficiency is observed in an alkaline environment and can reach 99 % depending on the conditions of the process. © Published under licence by IOP Publishing Ltd

VOCATIONAL-PEDAGOGICAL EDUCATION IN RUSSIA: HISTORICAL AND LOGICAL PERIODS

Introduction. Rapid social and economic changes demand new methods and forms of vocational training, reorganization of content of professional education, i.e. its modernizations which cannot be carried out without existence of the qualified pedagogical staff. Therefore, high-quality professional and pedagogical preparation becomes today not just one of education components, and, without exaggeration, a guarantee of social and economic wellbeing of the country. To provide due functioning of the system of vocational pedagogical education (VPE), it is necessary to understand its specifics and regularities of development; thus, it is necessary to track formation and evolution of the system.The aim of the study is to provide retrospective analysis at the organizational and substantial level of development of VPE in Russia as the social and pedagogical system.Methodology and research methods. The historical and logical approach has become the leading approach while researching the problems of VPE. It allows us to build the accurate sequence of formation of the system of training of teachers of specific disciplines and masters of vocational training; on this basis to reveal its shortcomings and possibilities.Results and scientific novelty. A brief background into history of the Russian and foreign vocational pedagogical education existing prior to the beginning of the 20th century is given. The chronology of development of VPE in Russia since 1920-s till modern period is presented. According to the key changes happening in a target and organizational-content part of VPE, six stages are distinguished and described. It is shown that development of this type of education as a social and pedagogical system is caused by socio-economic factors and administrative decisions; at the same time the VPE system has own regularities, principles of functioning and internal potential for further improvement.The relevance of the appeal to VPE history is emphasized. The reflection concerning the accumulated positive and negative experience: promotes more exact diagnostics of tendencies in this area; helps to avoid former mistakes and to level the existing contradictions; enables to choose the most effective strategy of development of VPE.Practical significance. The materials of the publication can be useful for scientific and practical workers who are taking part in training of teachers of vocational education and engaged in forecasting and design of development of the system of vocational pedagogical education
