Research of methods for intensification of oil production from lower cretaceous sediments of Goryacheistochnenskoye field
Authors: Bakraev M M , Bulyukova F Z , Dumler E B 
Published: February 2022

Abstract
The oil industry is faced with the task of determining the most effective technological schemes, while ensuring environmental and fire safety, which can increase the return of oil-producing reservoirs. During the development of the Lower Cretaceous oil deposits of the Goryacheistochnenskoye field, located at the eastern end of the Tersk Ridge, there is a tendency to decrease the flow rate of oil production wells due to deposits of hardly soluble asphaltene-tar-parfin substances in the elevator pipes. The drop in the well flow rate led to an increase in the temperature, pressure in the reservoir, as well as the intensity of deposits of colmating elements in the bottom-hole formation zone. The authors of the article propose to solve the problem of selecting an effective method of processing the near-well zone to increase oil recovery and by cleaning from colmating deposits. The main goal of the study is to identify the most effective way to treat the terrigenous near-well zone of the Lower Cretaceous formation in order to influence the skeletal structure of the reservoir rocks and combat colmating deposits. Various methods of impact on the bottom-hole zone of the well were studied. It is proposed to treat the terrigenous formation zones of the Lower Cretaceous deposits with organic RINGO-GKS and MKS solvents. Experimental fire-safe treatment of wells has shown an effective effect on the bottom-hole formation zone and its complete cleaning of colmatate deposits.

Published: February 2022

Abstract
The results of studying the fire foams’ modification using organosilicone compounds are presented in this article. The results of comparative fighting flammable liquid fires (diesel fuel) using non-modified foam and modified foam are also studied. It is shown that fire fighting using foam, modified with organosilicone compounds is much more effective, because of the increasing isolating capacity of such foam due to high-solidifying formation of foam which prevent the liquid vapors from getting in the area of chemical reactions and also isolate the flammable liquid from the oxygen of the air. Such a result is possible due to the presence of the mixture of solutions of foaming agent and the organosilicone modifying compound in the structure of the foam – tethraethyl silicate (TES). The results of the study confirm the perspective of using the organic compounds of the silica for improvement the fire extinguishing properties of the foam and its further applying for the fighting with flammable liquid fire.

Published: February 2022

Abstract
The article deals with the problem of controlling the emission of gases and suspended particles of thermal power plants. It is a closed system with mutual influence of physical processes (fuel preparation, fuel combustion, flue gases and particulate matter removal) on computational processes (fuel quality control, fuel combustion completeness control, control of permissible emissions into the atmosphere) and the reverse influence of computational processes on physical ones (fuel preparation modes change, fuel combustion modes change, flue gases and suspended particles removal modes change). The fault tolerance and predictability improvement of such a cyber-physical system is associated with an increase of the data reliability from existing feedback loops and the multimodality of physical process control systems.

Authors: Khakimova G V , Asfandiyarova L R 
Published: February 2022

Abstract
The soils of the industrial city were investigated using phytotesting methods. Cress salad was chosen as the test object. Toxicity was assessed based on a comparison of germination and total seedling length. Based on the experiments conducted, one can judge the close relationship between atmospheric air pollution and depositing media - snow and soil cover. The main centers of contamination were identified, priority sources of pollution were established. It was established that the distribution of pollutants in the city is influenced by the physical and geographical characteristics of the area and meteorological conditions for the dispersion of pollutants.
Polyvariance of ontogeny of Castilleja lapponica Gand. under industrial pollution of the Subarctic
Authors: Vasilevskaya N V 
Published: February 2022

Abstract
Studies of the cenopopulations of Castilleja lapponica Gand. - the endemic Arctic, North European species were carried out in the Lovozersky Mountains (Murmansk region). Monitoring of the cenopopulations of C. lapponica continued for 2 years under chemical and radiation pollution of the environment (30-60 uR/hr) by the Lovozersky Mining and Processing Plant where the tantalum-niobium ores and rare earth raw materials are mined and processed. Wastes of ore dressing are homogeneous sands, which are stored in the Tailing Dump. The study was held at stationary test sites in the tundra meadows and in the vicinity of the Karnasurt Tailing Dump. The polyvariance of ontogeny in cenopopulations of C. lapponica under the industrial pollution and in the natural environment of the tundra has been revealed. It is shown that under the technogenic stress, Castilleja, which reproduces in tundra meadows mainly vegetatively, switches to seed reproduction. Ontogeny spectra are unstable: in the first year of monitoring, seedlings are dominating, in the second - generative plants. Radiation stimulates the germination of seeds, the intensity of sexual reproduction increases, but most of seedlings are eliminated up to the next year. The high level of dooming of generative shoots and individuals, teratogenesis of inflorescences has been identified. The vitality of individuals decreases, the density of cenopopulations changes. Seed reproduction under conditions of the environment pollution by rare elements and radionuclides can be considered as an adaptation that contributes to the survival of C. lapponica.
Conceptual model for examining knowledge maps adoption in ecosystem of megacities
Authors: Mamai I B , Gayer A V 
Published: February 2022

Abstract
The high anthropogenic load on the ecosystems of megalopolises necessitates the search for non-trivial ways to maintain and preserve the quality of life based on intelligent decision support systems. The introduction of knowledge maps into the ecosystems of megalopolises is associated with the need to develop conceptual decision-making models. It is proposed to use neuro-fuzzy networks as a basis for constructing such models. Scientific and methodological approaches to the evolutionary construction of decision rules for knowledge maps based on a system of criteria are developed. The proposed approaches were implemented in the form of a program that allows building knowledge maps based on the resolution of environmental and socio-economic factors of load on the ecosystems of megalopolises.

Abstract
Beekeeping in Russia has been widespread for a long time and almost everywhere, a traditional and significant branch of the country’s agriculture. In the Russian Federation, as in most countries, beekeeping is mainly practiced by amateurs. In 2019, according to government statistics, there were about 4.0 million bee colonies in the country, with more than 90% of them in the private sector. One of the factors of high productivity of bee colonies is the hygienic activity of individuals. The behavior of the bees in maintaining cleanliness and hygiene in the hive is astonishing. Not only the honeycomb, but even the walls and floor of the hive are always kept neat, polished with propolis. Garbage falling to the bottom of the hive is immediately thrown out through the entrance. Moreover, large litter, for example, the corpse of a bee, is pulled out by the orderlies onto the boarding board, and, grabbing it with their legs, take off to carry it away from the hive. Worker bees sweep small debris out of the hive with their fan wings, like brooms, and even brush dust particles to the tap hole. Sterility in a honey bee nest can be compared to an operating room in a modern clinical hospital.

Obtaining effective biodestructors of fungicidal drugs for environmental agrobiocenoses’ maintenance sustainability
Authors: Kolotova O V , Mogilevskaya I V , Nefedieva E E , Zheltobryukhov V F 
Published: February 2022

Abstract
Agrobiocenoses are highly productive communities. However, their resistance is low due to the artificially limited species diversity, susceptibility to diseases and pests, and the impossibility of self-recovery. The constant use of pesticides for plant protection further reduces the resistance of agrocenoses due to the toxicity of the components for the soil microbiota and pollinating insects. The accumulation and migration of toxic components of pesticides leads to an increase in the environmental load on surface water bodies and aquatic organisms. The impossibility of abandoning the use of fungicidal preparations and the need to develop ways to increase the ecological stability of agrobiocenoses determined the relevance of the studies described in the article. In the course of the experiment, pure cultures of 9 microbial strains-destructors of strobilurins and triazoles - active substances of widely used fungicides -were isolated from environmental objects. A comparative assessment of the ability of the isolated strains to consume high concentrations of azoxystrobin and cyproconazole was carried out. It was found that the Bacillus thuringiensis strain, which is capable of growing on media containing up to 100 APC for soil in the absence of other carbon sources, has the greatest activity. B. thuringiensis is promising as the basis of a biological product for the recultivation of soils contaminated with fungicides of the strobilurin and triazole classes. To obtain the biomass of the biodestructor, the optimal cultivation parameters were determined: temperature 37 ºC and the composition of the nutrient medium based on glucose and peptone with microelements: Mg, Fe, Zn, Mn, B.

Authors: Temukuyev Timur B , Prazdnow Gennady S , Temukuyev Boris B 
Published: February 2022

Abstract
The article discusses the possibility of using hydrogen as an ideal alternative fuel with a zero carbon footprint. It can be considered as such only if it is obtained from the decomposition of water using energy from renewable sources, since hydrogen will no longer belong to traditional types of fuel, turning into an energy accumulator obtained from a certain source, with all the advantages and disadvantages of such devices. The economic efficiency of the battery is estimated by the efficiency. For the industrial use of hydrogen as a fuel, it is necessary to solve such technical problems as the choice of primary energy sources for the decomposition of water, storage and transportation of the resulting gases, as well as to determine the energy feasibility of introducing certain technological schemes. To assess the carbon footprint, it is necessary to determine the primary energy efficiency, that is, to identify the sources of used energy in all links of the technological scheme from the development of project documentation to the disposal of used equipment.

Abstract
In short-term vegetative experiment studied the effect of the different combinations of nitrogen and zinc fertilizers on the chlorophyll content in the leaves of spring wheat plants of the Zlata variety. It is established that application of nitrogen fertilizers together with zinc in most combinations contributed to stabilization of synthesis processes of chlorophyll grains in the leaves of wheat. It is shown that in conditions of optimal water supply and in the conditions of ecological stress caused by drought the most optimal combinations were ammonium sulfate with zinc and urea with zinc. With optimal water supply in variants where were applied ammonium sulfate with zinc and urea with zinc was obtained an increase of the amount of chlorophyll (a + b) compared with control variant without zinc, as a result of the growth of the content of both chlorophylls a and chlorophyll b. In the conditions of named ecological stress, the amount of chlorophyll (a+b) was increased in the variant with the addition of ammonium sulfate mainly due to chlorophyll a. In the variant where was applied urea with zinc the amount of chlorophylls (a+b) increased as a result of growth of chlorophyll a and chlorophyll b. It is shown that in conditions of drought in the specified variants had been increasing the ratio og chlorophyll a and chlorophyll b due to growth of chlorophyll b which indicates about improvement of water balance inside of the plant cells and increasing a photosynthetic activity due to normalization of processes of photolysis of water.

Published: February 2022

Abstract
The topic under consideration is relevant, since more than 80% of Yakutia is covered with forests, which is why this region is one of the most fire hazardous in our country. This year in Russia, in particular in Yakutia, there was a record number of fires. Since the beginning of 2021, 69 forest fires have occurred in Russia, that is, they have affected the lands of the forest fund. In 2020, 439,100 fires were registered, which is 6.9% less than in 2019. They killed 8,262 people, which is 3.5% less than last year. Among the dead, 355 were minors - 12.6% less than in 2019. There is no doubt that fires have negative impacts on all areas. Ecology is no exception. In this regard, in this article, the authors consider the environmental consequences of the fires in Yakutia that occurred this year.

Authors: Kovalev N N , Leskova S E , Mikheev E V 
Published: February 2022

Abstract
The microalgae Tetraselmis suecica is widely studied as a potential producer of triglycerides for biofuels production and number of biologically active substances. Artificial cultivation of microalgae is associated with its use as live food for bivalve molluscs cultivation, sea cucumbers and fish. The efficiency of microalgae cultivation depends on many environmental factors and is an economically demanding process. The use of exogenous stimulants - phytohormones, has a significant effect on the growth and cultivated microalgae biochemical parameters. It was shown that salicylic acid in concentrations of 1.0 - 3.8 x 10-8 M stimulated the growth of the Tetraselmis suecica culture. In comparison with the control, the growth of the culture by 415% was noted, with the addition of phytohormone at a concentration of 3.8 x 10-8 M. Under the influence of salicylic acid, the amount of protein increased 3.2 times, protein 1.3 times, and the synthesis of carbohydrates was suppressed. The caloric content of Tetraselmis suecica was determined by biochemical composition differences, which must be taken into account when determining the cultivation strategy for marine invertebrates, since a certain plastic material is required for each stage of metamorphosis. The toxicity of salicylic acid due to its accumulation in the environment is well known. The results obtained in our work will contribute to the expansion of knowledge about the effect of acid on microalgae and the potential for their use for wastewater bioremediation.

Published: February 2022

Abstract
One of the main challenges in pet roleum-containing wastewater treatment in municipal wastewater treatment plants is their interference with the microbiological processes of nitrogen and phosphorus removal. The purpose of the study is to assess the effect of commercial petroleum products on the conversion of nitrogen and phosphorus compounds during the biological treatment of municipal wastewater in activated sludge systems. The presence of commercial petroleum products in wastewater was found to inhibit the process of conversion of NH4-N and the absorption of PO4-P in cells. The main inhibiting effect results from additives introduced into commercial petroleum products. Variations in the removal efficiencies of NH4-N and PO4-P are due to the variable distribution of commercial petroleum products in the mixed liquor of activated sludge. An increase in the degree of dispersion of commercial petroleum products, which results in an increase in the contact surface, increases the inhibitory effect on the activated sludge process. The toxic effect of gasoline is more pronounced in comparison with diesel fuel and hydraulic oil. During the first 30 minutes of incubation of samples with oil products, an increase in the concentration of PO4-P in the solution was observed due to the death of microorganisms from toxic effects, mainly from gasoline.

Published: February 2022

Abstract
The sensitivity of seedlings of two wheat varieties to the model toxicant (boric acid) in two soil types was tested with the use of the method (FR.1.39.2016.24117). The soil with a high content of humus was less toxic then the soil with less humus level with the same content of toxicant. It is shown that it is expediently to use the same type of soil for the control for an objective assessment of the effect of the toxicant contained in the tested soil on the test-organisms. Also it is necessary to consider the plants adaptability for the environmental stresses during selecting test object, particularly wheat.
