Relevance of the discussed issue is caused by the necessity to expand the local mineral resource base of Tyumen region for producing a large range of modern building and insulating foamglass ceramics materials. The main aim of the research is to study the chemical and mineral composition of sediments of Turtass suite of Upper Oligocene to determine the possibility of their use as a raw material for producing building and insulating foamglass ceramics materials on the example of Uspenskaya area (Tyumen region). The methods used in study: field investigations, reconnaissance of the area, macroscopic study, X-ray fluorescence analysis, X-ray analysis, petrographic analysis, electron microscopy, diatom analysis, technological tests in accordance with the RF patent № 2464251 and TC 5764-001-90903792-2013. The results. The carried out investigations show that the significant content of frustules of diatoms and their fragments (10 %), formed by X-ray amorphous opal, combined with mixed layers of formation (corensite, tosudite etc.), which form the clay part, actively engages with weak alkalis and, consequently, define the opportunities for their wide use in production of foamglass ceramics materials. During the pilot testing the authors have obtained the samples of foamglass ceramics materials, which meet the RF patent no. 2464251 and TC 5764-001-90903792-2013 in part of bulk density, compressive strength, water absorption by volume, softening coefficient and thermal conductivity. Multifunctionality of the material allows planning the production of a wide range of products in demand in industrial, civil and low-rise wireframe, road construction, oil and gas industry, landscape design: building blocks, dry construction mixtures, fillers in concrete, foamglass ceramics blocks, bulk insulation for roads and grounds.

The paper presents an analysis of the priority directions of modernization of vocational training in the field of physical culture in the context of health-technology identified possible areas of its optimization from the perspective of a competent approach.

The paper presents the current state of autonomous energy sources in the north of the Far East. Consideration is given to the capacity structures with a focus on industrial and residential autonomous energy sources. One of the main problems facing power supply to residential consumers in the north of the Far East is the insufficiently developed transport infrastructure, which causes complicated fuel delivery patterns, fuel price rise, and hence high electricity generation cost. The changes in the installed capacity of renewable energy sources (RES) in the north of the Far East are demonstrated for the period between 2011 and 2015. The research shows the main directions of power production diversification in the north of the Far East. The directions include the use of local fuel types, the development of cogeneration, the involvement of renewable energy sources and small-scale nuclear power plants. The paper presents a forecast for the renewable energy development in the north of the Far East up to 2035, made by the authors. The priority RES projects in the off-grid power supply in the north of the Far East are wind and solar power plants

In this paper, we present new parallel algorithms for finite element analysis implemented in the FEStudio software framework. We describe the programming model of finite element method, which supports parallelism on different stages of numerical simulations. Using this model, we develop parallel algorithms of numerical integration for dynamic problems and local stiffness matrices. For constructing and solving the systems of equations, we use the CUDA programming platform.
