Authors: Shapovalova E A , Ganyaev V P , Pimneva L.A. 
Published: June 2019

Abstract
Currently, two methods of extracting iodine are mainly used: air-desorption and ionexchange. Common to these methods is the use of chemical reagents such as sulfuric acid and chlorine in the stages of acidification and oxidation, which are the main sources of costs in the production of iodine and environmental pollution. Therefore, the development of technology for the processing of reservoir waters in oil production with the goal of isolating such elements as iodine for further use is an urgent task of rational nature management. A new method for extraction of iodine from the geothermal reservoir water and oil and gas fields in Western Siberia, which eliminates the use of chemicals in the technological scheme, which reduces the environmental burden on the environment. This technology was tested in a pilot plant and can be used in the preparation of iodine-bromine water Cherkashinskoye field Tyumen Oblast of the Russian Federation.

Published: June 2019

Abstract
The article considers parameters of the influence of a high voltage source (HVS), as a form of the output voltage curve and its influence on the technological parameters of the electron-ion technology (EIT) devices for various purposes, the HVS schematic solutions and their classification. A equivalent circuit a single-zone electrostatic precipitator is developed, differing from the existing ones in that the differential capacitance is moved beyond the key VD, because the volume charge can be neglected until the moment of ignition of the corona discharge when considering the corona-discharge system, i.e. for simplicity, the condition is assumed that volumetric charges are created only by corona discharge. Based on this scheme, an equivalent electrical equivalent circuit for a two-zone electrostatic precipitator was constructed. The analytical expression for calculating the electrical constructive capacity of the most commonly used in the electrostatic precipitator corona-discharge system “a number of wires - a plane,” taking into account the additional electric capacity. The article presents the results of the investigation of the effect of the frequency of the output voltage of the HVS and the additional capacitance of the capacitor bank on the volt-ampere characteristic of the corona-discharge system of the electrostatic precipitator-ozonizer. The analytical expression is shown in general form, describing the volt-ampere characteristic of the electrostatic precipitator, taking into account the shape of the HVS output voltage curve. An analytical expression for determining the ozone concentration at the output of the EIT devices in the general case is also shown.

Published: June 2019

Abstract
The risk and quality assessment paper is dedicated to estimation of impact (for human health) of bottled drinking-water package (especially PET one). The investigation is concentrated on using one integral method for different risk types (factors connected with potential carcinogenicity: concentrations of antimony, formaldehyde, diethylhexylphthalate; and organoleptic factors: turbidity, colour, and pH). We imply the nature of organoleptic (quality assessment) factors close to risk ones because their indirect influence on polluting power of chemicals can be amplifying. The acceptable risk levels for these types are fixed as 10-1 and 10-5 respectively. The research is based on Russian and International (principally, American) scientific researches and standards. The calculation of risk metric is proposed to be estimated in dimensionless number (hazard quotient – HQ). HQ can be transformed in probabilistic numbers in conversion to events per million (Risk Index – RI and risk of olfactory-reflectory impact factors, Integral Index of Water Risk). In the article we used the idea of “chronic daily intake” (CDI) as an acceptable risk-free measure of factors of potential carcinogenicity, which is an adequate evaluation of permissible concentration. 5 brands of Russian bottled water were analyzed, it turned out that one of them had an exceeded acceptable level of risk.

Published: June 2019

Abstract
The spending energy for gas transportation reaches 10% of the produced gas. After the reaching of the consumer, this pressure must be reduced to a certain. The created energy of the gas in gas pipelines in compressor shop can be extracted in the mechanical energy form and delivered to the turbo-expander shaft. Using of new turbo expanders with asynchronous generators for the use of throttle gas energy will save energy costs for gas transportation in main gas pipelines. For reliable operation of the asynchronous generator systems and devices are needed to stabilize the voltage. The principle of the new device for adjusting and stabilizing the voltage of an autonomous asynchronous generator is based on the selective inclusion of capacitors with three-phase electronic keys as a function of the feedback signal from the output voltage.

Authors: Polonsky A B , Sukhonos P A 
Published: June 2019

Abstract
The physical processes that determine spatio-temporal variability of the upper mixed layer (UML) temperature in the North Atlantic have been investigated. The study of physical processes is based on the closed UML heat budget. The components for the mixed layer temperature balance are computed using the monthly data from ORA-S3 ocean reanalysis over the period 1959 — 2011. This paper deals with the relative contribution of heat budget terms into generating the both intra-annual and interannual-to-decadal variations of the UML temperature. The result of the study shows that the local heat flux on the ocean surface plays a major role in the intra-annual cycle of the UML temperature, while the nonlocal processes, such as advection and diffusion of heat, affect the interannual-decadal variability of the UML temperature. The obtained results are vital for studying the physics of ocean-atmosphere interactions.

Published: June 2019

Abstract
The modernization of mining lowered the number of air-dust-methane mixture explosions, but specific value of fatal traumatism has increased threefold. Most of the miners’ die from toxic gases poisoning in accidents, which means insufficient efficiency of personal protective equipment use. The cause of miners’ death was inability to behave in 52% of cases. Excessive stress in miners’ professional activity contributes the decline of self-control, forming disadaptive forms of behavior with characteristics of deviancy. Modelling escape to the surface using mine self-rescuers with chemically complexed oxygen among 84 individuals have had experienced protective equipment for respiratory tract has demonstrated that only 20% have covered the distance to the surface in estimated time. Strategy for solving the problems prevailed among this category of miners. The study was shut down for 80% of miners, and they had the strategy of avoiding the problems and support. Forming during respiration hyperoxygenated mixture with the help of mine self-rescuer helps forming circumstances for inadequate danger estimate and insecure behavior in extreme situation. Thus, miners’ preparation for action at risk should be realized according to the strategies of behavior while respiration modelling using mine self-rescuer, providing breathing hyperoxygenated gas mixture.

Published: June 2019

Abstract
Road traffic accidents, especially occurring on road sections outside of populated areas, are characterized by high severity of consequences and, therefore, are one of the main safety problems of the technosphere. Studies of many authors confirm the importance of the influence of meteorological parameters on the accident rate. However, most results don’t contain quantitative data demonstrating how risk of occurring a car accident depends on weather conditions. Research of this article assesses the impact of five main meteorological parameters on the accident rate using as example one of the Russian Federal roads. Nonlinear dependences of weather conditions and road accident risk were obtained by means of calculation of frequencies. The results are presented in the form of graphical dependencies. As a result of approximation there were found formulas that describe the relationship between values of meteorological parameters and the variation of a car accident risk. According to probability theory, the mathematical model can be based on the multiplication of risks caused by each meteorological parameter.
New Information on the Structure, Geological Development and Oil and Gas Potential of the Northwestern Territories of Yakutia and the Adjacent Shelf of the Laptev Sea

Published: June 2019

Abstract
In the XX-th century, scientific ideas prevailed on the genetic connection of the marginal Arctic territory, stretching far into the Laptev Sea shelf, with the mesozoids of the Verkhoyansk-Kolyma’s mountain-fold system. At the same time, this coastal strip of elevation was considered as the northwestern branch of this system. At the end of the last century, there have been significant changes in these views. The opinions of the geological development of the northern continental and adjacent shelf areas during the pre-Cenozoic geological epochs get very broad support under the conditions of a typical platform regime. The latest results of the seismic survey of the CDP-2D carried out in the Laptev Sea area was played an important role. The geological model of the structure and oil and gas content of the large area of the articulation of the continental land and the adjacent East Arctic shelf is justified and for the first time a preliminary characteristic of the new large Olenek-Laptevskaya oil and gas bearing region was given. The marginal structural-tectonic elements of sub latitudinal strike are constituent parts of the southern side of a large sedimentary basin, mainly located on the shelf Laptev Sea (Olenek-Laptevskaya syneclise). The tectonic regime of the concordative deflection, carried out earlier under the conditions of the passive continental margins of the Siberian Platform, was replaced with the conditions typical for the areas of interplate activation at the end of the Cretaceous and further in the Paleogene-Neogene. At the same time, the predominant stretching established earlier in the spreading zone on the continuation of the Gakkel ridge in the south-west direction was replaced by the conditions of regional subhorizontal compression. The obtained results indicate a regional continuation on the shelf of a large Riphean focus of oil and gas formation, established earlier by seismic prospecting in the northeast of the Siberian platform. As a result, it assumes the presence of a very significant hydrocarbon potential, much exceeding the high predictive estimates of past years.

Abstract
In the diet of the rural population, the main products of consumption were meat and meat products, bakery products, dairy, fruit and vegetable products. The greatest contribution to the population exposure to cadmium, arsenic, mercury when ingested with food products like milk and dairy products, meat and meat products, fish, bread and bread products. The most susceptible to the total nonspecific effects from domestic products are the cardiovascular system, the hormonal system, the central nervous system, the immune system, the blood of the kidney and the reproductive system, from the imported products - blood, hormonal system, central nervous system and reproductive system. With combined intake of pollutants by alimentary methods, the total index of the risk of development of non-carcinogenic effects was 16.2 (95% per cent) for domestic products, 4.6 (95% perc) for imports. The non-carcinogenic risk from contamination of domestic food products is formed by cadmium, arsenic and mercury. Systems most susceptible to total nonspecific effects are cardiovascular (HI) - 3.6, hormonal with an index of danger (HI) -2.7, the central nervous system with an index which is dangerous (HI = 2.4), immune (HI = 1.45), blood (HI = 0.88), kidneys (HI = 0.79), and reproductive (HI = 0.71). The influence of imported products on functional systems was distributed as follows: blood (HI = 0.48), hormones (HI = 0.81), cc HI = 0.52), reproductive system (HI = 0.41). With the combined intake of pollutants by alimentary methods, the total index of the risk of development of non-carcinogenic effects by domestic products was 16.2 for imported - 4.6.

Published: June 2019

Abstract
During exploitation of oil pipelines and storages oil spill can occur. For effective collecting spills sorbents are used. There are many types of sorbents, but sorbents that can be utilized in excess oil are very promising. The aim of the work is to study the properties of such substances, their applicability for oil spill collection and comparison with other sorbents. The object of the study was a sorbent that contains powdery polypropylene. A study of a number of basic working properties was carried out in laboratory conditions at room temperature of 20 °C. This sorbents creates a rubber-like formation like “carpet” that is easily removed from the surface. During experimental study the sorption capacity has been measured. Test of the buoyancy of the sorbent in water showed that after 20 days sorbent granules do not sink, do not swell and form no film on the surface, allowing water to evaporate freely.

Published: June 2019

Abstract
For the moment, a large number of mining enterprises in Russia engaged in the open-pit mining face with the problem of providing the stability of the directly-embedded concrete poles which are a part of the overall transmission power line system. The blasting operations considered to be an efficient way of developing the deposits strongly affect the concrete poles in the immediate vicinity from the quarries. The major part of electric poles near the deposits has critical deflections from the vertical position. The process of evaluating the stability of the poles affected by the blast-induced ground vibrations should inevitably include the process of determining the criterion of the loss of stability that will help to evaluate the level of the ground vibrations safe for the construction. The paper presents the methodical approach of evaluating the stability to be performed with the help of the finite element model and studies of the stability of a construction having various angles of deflection.

Published: June 2019

AbstractThe paper considers a new approach to identifying the possibility of saving pumping energy for in the oil trunk pipeline system by optimization the mixing ratio of the oils pumped to different directions in complicate branched network. To get the effect of energy consumption reduction, optimal mixing concentrations are calculated on the simplex space characterizing the composition of the oil blend. The problems of calculating the flow rate and required energy by a more explicit function type without iterative methods are considered. Attention is paid to determining the boundaries of possible ratios of blending taking into account the condition of mass balance. An example to solving the task aimed to optimization of oil flows distribution in condition of differences of their rheological properties in the case of the simplest configuration type of the pipeline network is also shown. The considered method presents the local nodal solution of a more complete transportation optimization task – The Maximum flow of the Minimum cost.

Abstract
The ground penetrating radar (GPR) is one of the most frequently recommended non-destructive methods for the pavement thickness measurement. Due to the rapid growth of GPR data in the recent years, the development of automatic data processing techniques is required. In this paper we propose to use one type of artificial neural network, the multilayer perceptron (MLP), for automatic selection of the pavement boundaries. The experimental results indicate that machine learning techniques can be used for robust road structure evaluation.

Published: June 2019

Abstract
Based on long-term data of chemical and biological monitoring, the risk of anthropogenic impact on urban water bodies was estimated (Kazan, Republic of Tatarstan, Russia). These chemical parameters were used as pollution markers: dissolved oxygen, BOD, ammonium compounds, as well as pollutants, which exceeded MAC (15 ingredients in total). The main biological indicators were the total number of phytoplankton, the relative number of oligochaetes in the composition of zoobenthos and the relative number of rotifers in the zooplankton. It is shown that urban aquatic ecosystems are in transition from equilibrium to critical state according to the degree of risk of anthropogenic impact.
Ecological and Hydrogeological Problems of the Old Industrial Regions of the Middle Urals (Russia)
Authors: Rybnikova L S , Rybnikov P A 
Published: June 2019

Abstract
Mining of mineral deposits leads to the formation of mining landscapes, within which specific hydrogeochemical systems arise. Following the dewatering to the depths of tens and hundreds of meters, processes of technogenic hyper-genesis and mineral formation are developing, especially in areas where the continuity of rocks is disturbed. Here, the sulfuric acid weathering crust is formed, which contains secondary minerals, including readily soluble crystalline hydrates of sulfates. The article presents the results of the analysis of the hydrochemical situation within the abandoned Levikha mine (Middle Urals). It is shown that the reason for the formation of unloading of acid mine waters on the surface during postmining is the change in the hydrodynamic conditions (cessation of the drainage and the filling of the depression cone), the dissolution of secondary minerals in the technogenic zone of hypergenesis (in the zones of collapse and displacement). The mass consumption of components at the post-operational stage is comparable to the rate of oxidative weathering of sulfides during the operation of the dewatering. The half-life of the components is about 5 years, and the formation of contaminated mine waters will last at least 50 years. These results are the basis for determining the strategy and tactics of planning work to eliminate the accumulated damage to the environment of the mining landscapes of the Middle Urals at the post-mining stage.

Abstract
This article deals with an urgent issue - that of the deficit of natural energy resources, ways of their sustainable utilization and the need to find new alternative energy sources. It proposes a way to improve the efficiency of energy usage as well as to save energy in a mechanical ventilation system through the heat recovery of ventilation emissions by platetype waste heat exchangers. Schemes of steam-curing the supplied air in ventilation systems featuring waste heat recovery and partial recirculation of exhaust air in a cold season have been developed for the dining halls of the canteen at Lipetsk State Technical University. This paper relies upon the results of microclimate parameter analysis in the scenarios of using the proposed scheme and the current direct-flow scheme of supplied air treatment in cold and transitional seasons. It provides conclusions on the possibility to attain optimum parameters of air inside the serviced rooms in case of implementing the scheme of steam-curing the supplied air with the recovery and circulation. The research also involved an appraisal of feasibility of using heat recovery installations in air ventilation systems.
