Authors: Gorbunova A D , Anisimov I A 
Published: April 2020

AbstractAt the present time, there is an increase in environmentally friendly vehicles, in particular it is introduction of electric vehicles. The variable operating conditions of these vehicles, which are characteristic of the Russian Federation territory, cause a decrease in the power reserve and an increase in the energy consumption. The use of existing methods to increase the power reserve of electric vehicles, which consist in the improvement of traction motors and energy storage systems, is impossible when it is in operation. However, the solution to this problem can be achieved by changing the modes of operation of electrical energy consumers, who receive it from a high-voltage battery. The article presents an analysis of previously performed work in the field of increasing the power reserve and reducing the electric energy consumption of an electric vehicle. The need to develop a classification of electric energy consumers, which will be one of the method stages for increasing the range of electric vehicles by controlling the power from electric energy consumers, has been identified. Experimental studies and highly specialized marketing questionnaires, which revealed the amount of energy required for the operation of consumers of electrical energy in an electric vehicle, were carried out.

Block Structure and Mora Circles for Stresses and Deformations
Authors: Chanyshev A I 
Published: April 2020

Abstract
Displacements associated with deformations are considered. The deformation vector at an arbitrary area with the normal

n

is defined as the ratio of the displacement vector of the site points to the distance from the site to the displacement reference point. The deformation vectors related to an arbitrary element of the medium have properties: their principal vector and principal moment are zero. For the strain vector, Mohr’s circles are constructed similarly to the stress vector. It is shown that, for an arbitrary area with a normal

n

, the work of forces corresponding to the stress vector on the relative displacements determined by the deformation vector depends, in the general case, on the loading path even in the case of applying the relations of Hooke’s law. The only areas where this effect does not exist are the stresses and deformations of the site that are equally inclined to the main axes. On this basis, a block model of materials (such as metals) is constructed, where the elements have the form of octahedrons.

Published: April 2020

Abstract
There is a discription of dynamical physical and chemical model of “flow reactor with an ideal piston displacement” type. With its help using the SELECTOR program complex (PC) for thermal solutions of Golovnin caldera (Kunashir Island, Kuril Islands) the numerical experiments were performed. The results of two “water-rock” type (W/R) systems modeling are represented: 1 – thermal solutions with pH=1.93; 2 – thermal ones with pH=6.35. The temperature range from 200 to 15 °C and the pressure of 1 and 10 bar in both experiments were used. As a results, data on the systems phase and chemical compositions were obtained; an evolutionary sequence of physical and chemical system states was identified with long-term water/rock (W/R) interaction; a metasomatism type for systems was gained; a metasomatic column was verified with ones near the orifice of thermal solutions. Thus, the complete correlation of model data with obtained in situ one was shown.
Compositional Interaction of Mica and Glass Waste
Authors: Fedorova S V 
Published: April 2020

Abstract
Mica belongs to a large group of minerals characterized by perfect cleavage, i.e. the ability to split into very thin sheets having smooth surfaces. Muscovite and phlogopite are the most important industrial micas. They are easily split into thin sheets. In addition, they have high hardness and mechanical strength. They are thermally and chemically stable, non-hygroscopic, flexible, elastic and transparent. Due to these properties, muscovite and phlogopite are the most important composite materials used for producing electrical insulating materials.
Technique of Determination of Commodity Cost of a Subsoil on the Basis of Calculation of Mineral and Raw Potential of Expected Resources
Authors: Dadykin V S , Okhlopkov M N , Gerashchenkova T M 
Published: April 2020

Abstract
Exploration and mining are logically interrelated. Currently, it is not necessary to carry out the work on reproducing the entire available mineral resource base, but only its cost-effective part. For forming investment projects it is required to assess the mineral resource potential of the territory. Calculating the mineral resource potential (MRP) typically includes data on reserves of deposits, estimated resources, the cost of subsoil and coefficients of bringing forecast resources to contingent reserves. The issues of a comprehensive study of the mineral and raw material potential from the point of view of a systematic approach, the efficiency of the mineral and raw material complex in the process of subsoil use, taking into account the specificity of solid minerals, are not well understood and require their scientific substantiation.

Authors: Kazak E S , Rodkina I A , Kazak A V 
Published: April 2020

Abstract
The paper presents data on water content separated into free, physically and chemically bound types for a collection of core samples from the Bazhenov formation. The rock samples came from 3 wells of Nizhnevartovsk arch, Western Siberia, Russian Federation. Each rock sample was a part of whole core with the maximum preserved natural water content. A suite of modern laboratory techniques includes evaporation method, derivatographic, and hygrometric studies. The results show that the content of chemically bound water (0÷6.4 wt.%) exceeds that of free (0÷1.87 wt.%) and physically bound (0÷1.0 wt.%). For the first time, we present the water content of mono-, poly-, and capillary condensation water obtained from the interpretation of adsorption isotherm. These data made it possible to draw a meaningful conclusion on mixed wettability of Bazhenov formation rocks.

Authors: Alexandrovskaya L N , Rosenthal O M , Kirillin A V 
Published: April 2020

Abstract
This paper describes analytical modeling of degradation of water treatment plants (WTP) during their extended operation; it also describes the algorithms for configuring such models on the basis of current WTP status readings so as to predict when the WTP deteriorates to the point it is no longer usable (time to failure).
Model selection is based on analyzing and generalizing a bulk of experimental data on various WTPs. Configuration algorithms are model-agnostic, which means the proposed approach can be used universally to improve water treatment quality while also cutting its costs.

Study of Bypasses for High-speed Passenger Trains, as an Alternative to the Reconstruction of Railway Stations
Authors: Kukleva N V , Kuklev D N 
Published: April 2020

Abstract
Nowadays, in order to organize the movement of passenger trains with speeds up to 200 km/h, it is necessary to reconstruct existing highways, which requires the need, in addition to performing a huge amount of work, to do it “under wheels”, i.e. in conditions of continuous movement, when it is often impossible to take trains to other routes (parallel passages), due to the lack of the last ones. As an alternative, the authors propose to consider the principal possibility of using bypasses for the passage of high-speed passenger trains, which in practice are often used for the organization of transit freight traffic, both individual railway stations and railway junctions in general. This allows not only to remove obstacles (“barrier places”) on the way of train traffic, but also to “unload” the existing infrastructure of railway stations and nodes. For this purpose, at the first stage, the factors that can affect the feasibility of using bypasses to perform such a task as the organization of high-speed passenger train passes were considered. The article can be useful for specialists, researchers who are engaged in the solution of issues on the organization of high-speed passenger traffic in terms of the preparation of existing highways in general, and railway stations in particular.

Authors: Tashbulatov R R , Karimov R M , Mastobayev B N 
Published: April 2020

Abstract
The article proposes a methodology for calculating the factors of rational mixing of oils with various rheological properties that are jointly transported through an extensive system of trunk pipelines to save energy demands for pumping. The calculation is aggravated by the absence of additivity of viscosity of specially formed multicomponent blends of oils that compels the calculation in a simplex place that characterize the possible compositions of oil blends. It is proposed to use the standard polydimensional optimization strategy as the main calculation module. The objective is presented in the form of summarized energy demand for pumping depending on the concentration of oil blend at the nodal points of their blending. There is proposed a method for calculating the objective for any extensive network of oil trunk pipelines using algorithms of constructing a blend tree and determining its properties using traversal tree algorithm.

Published: April 2020

Abstract
Three-dimensional analysis is an important and actively developing area in calculating the stability of slopes. The work was based on the results of the stability analysis of the landslide slope on the left side of the Kuban river valley above the Krasnogorsk hydropower station. The calculations were performed using the limit equilibrium methods in the three-dimensional formulation of the problem, taking into account the seismic effect. In this paper seismic effects were taken into account using the pseudostatic method. Based on the performed mathematical modelling it was shown, that direction of seismic impact changes not only the safety factor but also the spatial position of the potential landslide massif. This study proves the importance of three-dimensional calculations in the development of engineering protection measures against landslide processes.

Published: April 2020

Abstract
No living person can do without vegetables and fruits, food grown in the fields, kitchen gardens or in greenhouses. Those crops that are less whimsical to their surrounding nature and the conditions of growth and fruit formation are grown in open ground, and those that are more demanding, but at the same time not less necessary are grown in protected ground, or greenhouse. In this article, an analysis was conducted of the influence of the main harmful and dangerous production factors on the organism of workers in the greenhouse complex. When working in greenhouses, employees complain of discomfort from exposure to bright light and ultraviolet radiation during artificial irradiation and lighting up of plants. In the work, a comparison of frequently used types of lamps in greenhouses was made and it was revealed among them that it is safer for workers. Recommendations for improving working conditions are given.

Authors: Gilmutdinov D V , Mikriukov P E , Kolchin A V 
Published: April 2020

Abstract
Numerous natural gas liquefaction technologies for the main gas pipeline are known, however, this process is little used for the potential use of electric energy and is poorly implemented at the GDS, where it is possible to carry out low-tonnage LNG production. The object of research is gas distribution station (GDS) “Novo-Alexandrovka” with a capacity of 45 m3/hour. In the course of the research work the technological scheme of liquefaction of natural gas was developed on the basis of the available parameters at the mentioned GDS. This topic is topical due to the annually growing demand for liquefied natural gas. Currently, the LNG market in Russia especially is not developed due to the lack of proper regulatory governability of use and production, lack of cryo-filling stations and a clear program of development of gas vehicles. It is proposed to introduce a liquefied natural gas unit with a main temperature reduction unit through adiabatic expansion in turboexpander. The paper discover construction decisions and analysis of the dependence of the liquefaction temperature of natural gas on the inlet pressure into the gas distribution network as well as The technical and economic characteristics of the implementation of the liquefaction unit at the “Novo-Alexandrovka”.

Authors: Korenkova E A , Stepanova E I , Yakovleva E V 
Published: April 2020

Abstract
The article discusses one of the waste management areas – the use of fertilizer properties of chemical compounds that make up various types of production waste. The salt aluminum slag of the Mtsensk metallurgical plant AOOT Non-ferrous Metals and Alloys was chosen as the object of pollution. The presented studies indicate that the presence of macro-and microelements in the composition of slag fertilizers significantly increases the value of these fertilizers and partially solves the problem of complex application of the necessary elements into the soil [10]. The effectiveness was evaluated of the fertilizing properties of the salt screenings of aluminum slag, vermicompost and zeolites when using them as a part of nutrient soils for growing cucumber [8]. An increase in the toxic load for the analyzed period was established [7]. Also, all the studied forms and types of fertilizer nutritional compounds have a physiological effect, increase the growth and development of cucumber plants, product quality, and contribute to plant resistance to adverse environmental conditions and to the production of environmentally friendly products [13]. The effectiveness has been proved of the method of using plant cell juice electrical conductivity to assess the physiological state at different growth phases as a reaction to the fertilizer levels of production waste and natural minerals [9].
