Authors: Velichko E I , Polyakov A V , Dubov V V , Prikhodko M G 
Published: March 2021

Abstract
Currently, high-viscosity oil fields are actively developed in the world. This is due to the depletion of world reserves of light oils and a significant resource of heavy high-viscosity oils. The viscous oil production requires a solution to the issue of its transportation, which becomes much more complicated. This is determined by greatly increasing pressure loss due to hydraulic resistance when pumping heavy oil. To reduce the loss of the head, the pumped oil viscosity should be decreased. The paper considers improving the efficiency and transportation of high-viscosity oil by emulsification and creating a coaxial flow.

Abstract
The especial feature of high-latitude productive fields on the Arctic shelves is unusual geodynamic regime of the subaqual frozen bases enriched by methane gas-hydrates.Permafrost layersinto bottom sediments had been formed during the Ice Age, and after deglaciation the both permafrost and gas-hydrates came in a stage of instability and destruction, accompanying by hazardous effect on the man-made technosphere objects.Since 1937 constructing rules in the Russian permafrost areas were based on the 4-phase model of frozen soils: “mineral matrix – water – ice – gas” (MWIG), but new data on a distribution and structure of the relict subaqual permafrost on the icy shelves revealed an abundance of the new 5-phase type of frozen soils, named as SSGH – “Frozen Soil Saturated by Methane Gas-Hydrates” Preliminary assessment of potential risks for megascale constructions, which would be installed on the shelves, is presented in the article. It is shown that lack of sufficient scientific knowledge about geomechanical behavior SSGH when they serve as a ground base for extra-large engineering facilities. Evidently that fluidodynamic processes, associated with SSGH response ona technogenic stress or climate variations, have to be in a focus of engineering exploration into developing areas, and so the permanent geophysical monitoring during oil and gas field recovering on the Arctic shelveshas to be appointed as the obligatory requirements for large developing projects.

Authors: Buranshin A R , Godovskiy D A , Tokarev A P 
Published: March 2021

Abstract
In the process of gas main transportation, repair work is periodically required with cutting off the extended section and emptying the internal cavity of the pipeline. According to the established practice, gas from the cut-off section is released into the atmosphere. Ejectors may be involved in gas scavenging, but due to pressure reduction in the cut-off area, it is necessary to ensure high efficiency of the gas ejection unit. It is proposed to compare different configurations of ejectors at reduction of pumping gas pressure (single-stage ejector, ejector with inner cone, two-stage ejector). The ejector parameters are defined using the ANSYS Fluent CFD package. For each version of ejection unit, a graph is drawn on the dependence of the intake gas flow rate on the intake gas pressure, the inner cone position in the nozzle and the active gas pressure in the first stage of the ejector.

Published: March 2021

Abstract
Improving the technological component of agro-industrial production through the introduction of digital technologies accelerates the pace of economic growth and contributes to ensuring food security. The adaptation for agriculture of digital technologies already used in various industries is particularly relevant, and their integrated use is more effective. Artificial intelligence systems and, in particular, computer vision have significant prospects for implementation in the production and processing of agricultural products. Computer vision and image processing procedures can be used to control product quality and processing cycles in order to improve the efficiency of production processes. In each processing cycle, it is necessary to control the technological parameters and the quality of the processed raw materials, the results of which affect the duration, the number of operations and the conditions of the processing process. The use of the developed luminescent method to control the moisture content and particle size makes it possible to increase the efficiency of technological processes for processing grain products. The development of an innovative complex for deep processing of grain, as an example of application of new production technologies, is a promising current direction in the development of agricultural production. Increasing production efficiency is based on a significant expansion of the range of finished products, on an increase in the added value of processed products and on a slight decrease in capital costs due to the combination of processes. The increase in the potential for using various end-to-end digital technologies in agro-industrial production is facilitated through their combination and integration into complex systems for digitalization of production, which ensure the development of the agro-industrial complex.
Technological Innovation to Reduce the Negative Environmental Impact of Industrial Wastewater
Authors: Grakova A G , Novikova M A , Borisov A V 
Published: March 2021

Abstract
Rational use of natural resources and protection of water bodies is an actual problem of the modern world. Due to the rapidly developing industry, wastewater which contain high concentrations of suspended substances and organic pollutants is discharged to water bodies in a large volume.
So design improved treatment facilities that ensure high quality of treated water is an important task.
Biomembrane technology is a promising direction in water treatment, providing high efficiency of treatment at minimal cost. Compared to the traditional treatment scheme, it allows you to avoid the use of secondary settling tanks by separating the active sludge from the treated wastewater on the membranes. Due to the very small size of the membrane pores, almost complete removal of suspended substances and microorganisms is achieved. A bioreactor with an external arrangement of the membrane module provides high specific capacity.
The small-bubble aeration system in the aeration tank ensures the maintenance of dissolved oxygen at a concentration of 2-3 mg / l for the correct course of the nitrification and oxidation of organic substances. The combination of biological treatment and membrane separation ensures high operational reliability and durability.
This technology is used in various industries, but it is most widely used in the food and oil refining industries due to the high content of organic pollutants, which are mostly removed by this installation.
The use of biomembrane technology is economically advisable for designing treatment facilities for industrial wastewater treatment from organic pollutants.

Published: March 2021

Abstract
Quality control is an integral part of production process and sales and one of the main means conformity of the products in line with established requirements.
Meat products belong to the category of the most valuable food products. Freezing is a low-temperature preservation method. It provides the development of microbiological processes and a sharp reduction in the rate of enzymatic and physical-chemical reactions sacrificing the quality of the product.
There are some methods for evaluating the quality of meat products. One of the promising methods of complex research in this area is the impedance method. An important property of biological tissues is the dependence of their conductivity and relative permittivity on the current frequency. There is a dependence of frequency on electrical resistance dependency in the same way.
Its electrical characteristics also undergo changes, given that the cellular structure of meat changes during freezing. These changes are caused by the cell membranes destruction. As a result, the conditions for the passage of electrons and ions inside the meat change.
Impedancometry offers a wide range of possibilities for determining the meat freshness, the storage conditions correctness, compliance with technological modes of processing meat raw materials, in particular, the number of freezes that meat raw materials have undergone.
The bioimpedance meter will allow you to set the standard indicators typical for each type of meat, exceeding which would serve as evidence of the unsuitability of meat as a food.

Authors: Lebedeva E G , Kharitonova N A , Chelnokov G A 
Published: March 2021

Abstract
Chemical composition, distribution, structure, and numbers of different physiological groups of bacteria as well as their biodiversity have been researched. It has been shown that thermal waters are alkaline with low-TDS, Na-HCO3 type, and enriched in boron, lithium, arsenic, and strontium. The content of organic carbon in groundwaters from studied wells is low. They show uneven distribution, low diversity, and numbers of physiological groups of bacteria. The most insufficient numbers and the least diverse composition of physiological bacterial groups were registered in the groundwaters of higher temperatures. The study discovered the prevalence of chemolithotrophic thionic bacteria in the community structure, thus indicating the prevailing bacteria-induced oxidation of reduced sulfur compounds in the groundwaters. Silicate, iron- and manganese-reducing microorganisms also prevailed in groundwaters of wells No.3-87 and No.3-51. Low biodiversity of microorganisms with a significant prevalence of Bacillus sp. (50-60%) spore-forming bacteria in the taxonomic structure has been revealed. Thermophilic bacilli mostly included the species of B. flexus, B. licheniformis, B.subtilis, B. cereus, and B. cohnii.

Published: March 2021

AbstractIt is known that the concentration of the pollutant can be reduced by adding a reagent, which increase the rate of pollutant’s decomposition. In framework of the optimization approach, the problem of decreasing of the pollutant’s concentration is reduced to the multiplicative control problem for a nonlinear model of reaction-diffusion- convection. In the model under consideration, the reaction coefficient rather arbitrarily depends on both the concentration of the pollutant and the spatial variable.
