Authors: Makarov O A , Bekker A T 
Published: March 2021

Abstract
In recent years numerical modelling is widely used for solving ice-structure interaction problems. The most popular numerical method is finite element method. One of the promising approaches for modelling ice destruction is cohesive element method, where ice field is discretized using both bulk and special cohesive elements, which are possible crack paths. The investigation of modelling features and limitations of this method have been performed by several authors but with not appropriate quality. This paper belongs to series of numerical experiments performed to study the cohesive element techniques for ice modelling and includes some considerations and study of influence of finite element shape.

Abstract
The level of implementation of information and communication technologies in agriculture changes the demand for information support for crop production management. The study showed that the main criteria for selecting mobile crop applications in Russia are recommendations from friends and colleagues, content and timeliness of data updates, cost of use, language, user reviews and ratings. According to the scope of application, the author has identified the following groups of mobile applications: management of technical means; control and measurement of technological parameters; production planning; management decision support, knowledge development, communication and consulting; sales and purchasing organization. The most popular applications for Russian crop production workers are applications for precision farming technologies, navigation, agro calculators, nitrogen management, process maps and reference books. The results obtained differ from the global ones and are explained, in our opinion, by cultural and geographical characteristics, the level of digitalization of the economy, education, and technology.
Smart Rural Settlement: Digitalizing the Quality of Life
Authors: Kurcheeva G I , Klochkov G A 
Published: March 2021

Abstract
A targeted approach to digitalization of the quality of life in rural settlements is considered. The decline in the rural population is evidence of the continuing lag in the quality of life of the rural population from the urban one. Along with this, new indicators related to digitalization appear, such as the number of computers per household, the availability of mobile communications, and others. The growth of these indicators among the rural population is close to that of the urban population, which allows setting goals and performance criteria to improve the quality of life based on digitalization. The main tool, in this case, can be websites, which we analyzed for all districts of the Novosibirsk region; this procedure does not require large capital investments, but allows solving many problems of a social and public nature.
Consideration of Multiscale Permeability Studies of the Formation for Creation of the Targeted Permanent Geological and Technological Model of a Cavern and Pore Collector
Authors: Kozyrev N D , Kochnev A A , Mengaliev A G 
Published: March 2021

Abstract
The geological-hydrodynamic model of the reservoir is very important in predicting of oil field performance. Reliability and accuracy of the forecast depend on the quality and quantity of the initial information. The assessment and accounting of the results of various methods of reservoir analysis is often carried out separately from each other and at different times of model creation. As a result, it becomes impossible to describe clearly physical processes occurring in the formation. In addition, the degree of uncertainty of the reservoir properties remains high, even with a sufficient information. So a comprehensive analysis of all initial information is needed. The paper presents a methodological approach for integrating multi-scale data. Based on the clarification made Cuba permeability of the reservoir complex manifold in “Vostochno Lambeyshorskoe” field. Taking into account all borehole studies allowed reducing the degree of permeability uncertainty and more accurately assessing the filtration processes occurring during the development of the field. The proposed method of aggregation is universal and can be replicated for all oil fields with different degrees of study. information search engines rely heavily on the content of titles and abstracts to identify the corresponding articles in literary searches.

Glaukonite from Deposits of Different Age in Mountain Crimea
Authors: Georgievskiy A F , Bugina V M 
Published: March 2021

Abstract
The article describes glauconites, which in stratigraphic section of the Crimean Mountains, are mainly localized among Alb-Cenomanian, Maastricht-Danian and Eocene deposits. The study of isolated mono fractions made possible to identify the characteristics of glauconites of different ages and different generations. Three generations are distinguished, reflecting a sequential series of glauconite transformation at different stages of sedimentary rock formation. Generations differ in density, electromagnetic, structural, and chemical properties. Together, they allow to consider glauconites as heterogeneous illite formations with a variable content of swelling smectite layers, replaced by “hard” illite packets. This led to stabilization of the glauconites structure and their self-purification from Mn, Ti, V, Cr, Ni, Co, Cu, Zn. At different stratigraphic levels glauconites also differ in trace contaminants. In Alb-Cenomanian glauconites V, Cu, Zn accumulate above Clark. Danian varieties are enriched in Cr and a little in V, and Eocene glauconites - Mn, Ni, Co, and B. The glauconites formation was an intermittent, multi-stage, recycling process. Their main mass was formed during diagenetic crystallization of Al-Fe-Si gel. The process was repeatedly interrupted by sediments’ rewashing and roiling by waves and currents. Then the glauconites formation renewed again in the form of microconcretions or of outgrowths, coatings, and shells over rewashed glauconite grains. The maximum concentration of glauconite occurred at elevated offshore areas during erosion and rewashing of glauconite-containing sediments, as well as in depressions below the wave erosion base. Diagenetic glauconite formation was optimally combined with the accumulation of glauconite grains, transported by sea heaving and currents.

Published: March 2021

Abstract
The environmental hazard is the transport of toxic ions and aluminium oxides entering the hydrosphere. In addition to solving global issues of maintaining environmental wellbeing through sustainable development, it is necessary to solve the technological problems of cleaning water bodies from excessive aluminium. One of the effective measures to solve such problems is the use of phytoremediation - a set of methods for treating wastewater and water bodies with the help of aquatic plants. The study of aquatic organisms (hydrobionts) ecology shows how do they affect the physical and chemical parameters of the environment, including the hydrosphere. Our study in measuring the concentration and toxicity of aluminium ions in the aquatic environment based on the results of experiments with aquatic plants (macrophytes) Ceratophyllum and Chara fragilis, as well as with the higher aquatic plant Callitriche palustris Linne showed the possibility in initiating self-purification processes of hydrosphere objects from mentioned pollutants. Another option in preventing hydrosphere pollution by aluminium compounds should be based on implementation the noospheric transformation of the educational system for national economy specialists in accordance with proposals, given in the paper.
Hydrodynamic Causes of Vibration in the Pipe Bend of Process Pipelines
Authors: Tokarev A P , Spirin S E , Godovskiy D A 
Published: March 2021

Abstract
Hydrodynamic vibrations can occur both in pump piping at local resistances and in the pump, for example, when it’s operated outside the working area. Vibrations occurring in the hydraulic section of the pumps and associated pipings are transmitted to the mechanical section and can lead to breakdowns. Oscillations of pump piping can be caused by both hydrodynamic reasons and vortex formation at local resistances, and resonance with the natural frequencies of the piping. In some cases, the vibration of pipelines exceeds the permissible norms by 1.5-2 times. The range of vibration frequencies of a hydrodynamic nature directly depends on the flow rate of the working medium. As the latter decreases, the range also decreases. In any elbow of the pipeline, with a sufficient flow rate of the liquid, vortex formation occurs, which is the cause of forced vibrations. The values of the Strouhal number characterizing hydrodynamic phenomena in unsteady flow regimes for the flow of liquids in local resistances of pipelines have been studied very little.

Authors: Myalo O V , Myalo V V , Demchuk E V 
Published: March 2021

Abstract
Diagnostics in place is used for on-the-go monitoring of internal combustion engine condition in tractors. When an engine is running, motor oil is continuously interacting with the engine processes, which is why change in motor oil quality is used as the criterion of such interaction. This research used two diagnostic methods: oil spectrometry to detect the content of wear products in used oil as well as the content of silicon, sodium, and metals from oil additives; and spot check to determine the total contamination of oil, its water content, and dispersancy. Studies found out the characteristic indicators of change in the engine’s technical condition. The authors were able to obtain dependencies that can be used to find out the diameter of additive diffusion spots, the radii of contamination / additive / pure oil zones. The paper establishes how oil quality correlates with the technical condition of the engine. A combined analysis of two oil and ICE assembly diagnosis methods produced the reference values for oil spot checks.
Technologies and Machinery for Tillage on Slopes
Authors: Myalo V V , Myalo O V , Demchuk E V 
Published: March 2021

Abstract
With slope farming, land improvement operations shall be adapted to successfully counteract both wind and water erosion, as well as their joint effects. Paraplowing and chisel plowing are considered the most effective for controlling water erosion in the Western Siberia region, where the steepness of slopes in most areas does not exceed 4-6 degrees. However, even relatively small slopes have large areas where the required direction of machinery movement is difficult to determine unambiguously, while incorrect tillage significantly enhances erosion processes on the slopes. A number of disadvantages of existing tools can be eliminated with the help of a rotary-type blade tiller developed by Omsk SAU. As the machinery moves, the tool creates intermittent grooves of a complex configuration on the field surface, which allow to restrain the flow of melt and storm water. With a working depth of over 40 cm in the middle of the furrow, the tool operates partly as a paraplow keeping the crop residue on the field surface. However, this tool needs further modernization. Therefore, research aimed at creating and improving the tool pieces of tillage machinery capable of working on slopes of complex configuration is currently relevant.

Formation of Hydrocarbon Deposits in the Riphean-Lower- Paleozoic Sedimentary Basin in the Southern Siberian Platform
Authors: Marsanova M R , Berzin A G 
Published: March 2021

Abstract
In fluidodynamic theories activated deep faults with a key characteristic "activated" are an important and integral part of the oil and gas basins. The influence of fault tectonics on the processes of oil and gas formation is generally recognized and reflected in a variety of publications, but the mechanism of influence that is associated with the activation parameters: cyclicity of manifestation, generation redirection, time and the period of activation of fault systems, remains insufficiently studied [10, 11, 12, 13, 14].
Previously, in the marginal depressions of the east of the Siberian platform (Viluy Syneclise), carried out by several sedimentary basins (OPB), periodic processes of different ages activation of previously laid deep fault systems with various directions and generations were established.
It’s argued that the formation of hydrocarbon deposits in the synchronous sediments of the same Riphean-lower Paleozoic OPB on-site of Nepa-Botuoba anteclise was due to subvertical fluid flows from underfoundation sources and processes of reformation of hydrocarbon deposits between productive layers under the influence of the periodic re-activation of fault systems with different spatial orientation. Deposits in productive formations of the terrigenous Vendian complex form under the influence of fault activation of early North-East, North of the North-East and submeridional generations. But in productive carbonate horizons of Wend-Cambrian and Lower Cambrian deposits form at the cost of reformation of deposits in the vendian deposits as affected by late north-west generation faults in the zones of overlaying on earlier generation. Oil exploration in the carbonates is recommended in the areas adjacent to the selected fault systems.
Study of the Effect of the Film-Forming Substance on the Corrosion Resistance of Intumescent Paints

Published: March 2021

Abstract
One of the simplest and most effective fire protection methods for building structures is the application of a fire retardant intumescent coating on the surface of a structure. These swelling (intumescent) type coatings are widely used today. Intumescent coatings can increase the fire resistance of polymer compositions, but they have insufficient chemical resistance, resistance to high humidity. As a result, corrosion pockets appear on the surface of the steel structure and under the coating during long-term operation, the coating peels off, and cracks appear on it, and adhesion decreases. The purpose of this work was to determine the effect of a film-forming substance (binder) on the resistance of intumescent paints to the action of a corrosive atmosphere. For this, intumescent compositions with three different binders were made. The paint composition was applied with a brush to metal plates. For the experiments, samples of St 3 were used. The problem was solved, which was aimed at studying the heat-insulating properties of the studied coatings and the microhardness of metal samples under it. As the main criterion for evaluating the fire retardant properties, the heating time of the metal substrate of the sample was used. It was revealed that three paints obtained satisfactory results and can be used in industry. But epoxy binder paint got better results.
Technique for Justifying the Amount of the Redundant Developed Reserves Considering the Content of Metal in the Mining Ore
Authors: Rysbekov K B , Toktarov A A , Kalybekov T 
Published: March 2021

Abstract
An analysis of the preparedness of reserves in the Kazakhstan quarries has shown that in a real production process, periods of stable mining unit operation alternate with failures when the ore mass is not fully or partially supplied over the estimated time in the targeted amount and quality. To eliminate the production process breakdown and ensure continuity and consistency of the individual mining cycle stages, redundant mining units with developed reserves should be provided.
A technique for justifying the prepared ore reserves is proposed considering the variability of the active mining face parameters based on a statistical analysis of data of operating mining enterprises. To determine the dependence of the produced raw material qualitative composition homogeneity on the number of open pitiable mining faces, the actual weekly-daily schedules of the mining operations of several quarries (test pit 1) and (test pit 2) have been used. It is assumed that under the conditions of an operating mining enterprise, some averaging process parameters independent of the number of mining units may be considered constant and determined based on the operation data. Therefore, the solution to the problem of determining the effect of the number of mining units on the ore flow averaging level can be simplified.
The dependence of the useful component content on the number of operating mining units has been studied. A regression analysis of statistical data has been performed. Based on empirical dependencies, formulas for simplified calculating the amount of redundant developed reserves considering the required quality of the extracted ore have been obtained.

Published: March 2021

Abstract
This article discusses experimental studies of the use of local vermiculite from the Inagli field (Sakha Republic (Yakutia), Russia) as a recultivant on industrially disturbed permafrost-soil ecosystems of Yakutia after emergency oil spills. A brief description of the material composition, physical, chemical and technological properties of local vermiculite, which are close to the properties of vermiculite of the Kovdorskoe field (Murmansk oblast, Russia), is given. The sorption properties of Yakut vermiculite were tested on oil from the Talakan field, gasoline, diesel fuel, and toluene. Vermiculite of the Inagli field is a promising raw material for the production of oil sorbents, especially in connection with the increase in oil production, processing and transportation on the territory of Yakutia. The results of experimental application of hydrocarbon-oxidizing microorganisms (HOM) immobilized on vermiculite in oil-contaminated soils are presented. The technology of using vermiculite raw materials for oil pollution cleaning of various types of permafrost soils provides a significant environmental and economic effect, contributing to reducing the time of rehabilitation of disturbed lands and improving the environment of the disturbed territory.
