Authors: Djuraev Khayrullo , Yodgorova Mamura , Usmonov Akhtam , Mizomov Mukhammad 
Published: October 2021

Abstract
The article presents the results of studying the influence of such factors as the contact surface of the phases, the degree of grinding of the material, the nature of the flow and the ratio of the two phases called the hydro-module. It has been experimentally proven that at a hydro-module of 1: 4.1: 5, soluble components diffuse to the surface of the material, mixing and dissolving almost completely. By choosing a more acceptable hydro-module, it is possible to obtain a large percentage yield of the extract with the most valuable components, as well as to intensify the extraction process.

Physiological changes in the blood of calves by plant food when using Katozal
Authors: Yu Zavalishina S 
Published: October 2021

Abstract
An increase in livestock productivity is closely linked to an increase in calf vitality. This can be achieved using a number of approaches, including through the use of a number of biological stimulants in calves. The effectiveness of their use can be determined during the assessment of the main hematological parameters. As a result of 7 courses of daily use of 15.0 ml of Katozal plant nutrition in calves per animal, physiologically optimal changes in blood parameters were achieved. The results obtained as a result of regular injections of Katozal are regarded as highly physiologically beneficial for increasing the viability of animals and increasing their productive potential. The achieved dynamics of hematological parameters can be considered as a marker of the formation in the body of calves under the influence of Katozal of the situation, contributing to a pronounced increase in the processes of anabolism. The use of the drug Katozal is very promising for biological stimulation of calves at the end of early ontogenesis.
Adaptation of wheat varieties under combined stress
Authors: Gurova T A 
Published: October 2021

Abstract
The article presents the results of studies of adaptive reactions of 10-day-old seedlings of wheat varieties Novosibirskaya 18, Novosibirskaya 44, Sibirskaya 21 and Omskaya 18 under combined stress. The indices of growth, accumulation of wet and dry biomass and permeability of cell membranes by specific electrical conductivity (EC) of leaf extracts under the combined action of chloride salinity (1.3%) and hyperthermia of seeds (43 °C) were studied. Chloride salinization without preliminary heating of seeds caused mainly a decrease in adaptive capacity and a loss of cultivar resistance (a decrease in growth to 57.2%, a decrease in biomass to 35.2%, an increase in EC up to 5.7 times). The most resistant cultivar is Omskaya 18. Preliminary hyperthermia of seeds increased the resistance of seedlings to the subsequent action of chloride salinization (decrease in EC to 56.2%, inhibition of biomass accumulation and growth by up to 14 times). The protective effect of hyperthermia during the subsequent action of salinity is most pronounced in the Sibirskaya 21 variety.

Abstract
Commercial sturgeon breeding is one of the promising areas of aquaculture. This is not only an integral part of the production of valuable protein products, but also the main source of replenishing the number of sturgeon fish, especially rare and endangered species. This paper examines studies on the influence of environmental factors on the development and safety of sturgeon fry in a sturgeon breeding enterprise in the Krasnodar Territory, carried out on juvenile Russian sturgeon. It was found that the control group was reared for 213 days, the experimental group for 152 days. The average water temperature during the growing period was 20.39°C for the control group and 21. 19°C for the experimental group. The oxygen concentration was at the level of 73.6% in the control group and 76.6% in the experimental one. The pH level in water for the control group was 8.15, for the experimental one – 7.51; the concentration of nitrites for the control group was 0.025, for the experimental group it was 0.017. The average nitrate index is 0.96 and 0.84, in the control and experimental groups, respectively. The weight growth of sturgeons of the first group was higher, with the same initial weight, the final weight of juveniles in the experimental group was 97.4 grams, which is 14.8 grams more than juveniles in the control group. And the weight gain was 174.4% in the control group, and 222.5% in the experimental group. The average linear growth was also higher in the experimental group – 25.8 cm, in the control group – 24.1 cm. The increase in length was 76.7% in the experimental group, 68.5% in the control group. The survival rate of juveniles in the experimental group was 90.7% (136 specimens of Russian sturgeon out of 150), in the control group it was 86%.

Published: October 2021

Abstract
The article presents the field experiments’ many years results on the leaves photosynthetic activity manifestation varietal aspects study in spring wheat plants. It was shown on 25 modern cultivars that the leaf photosynthesis intensity significantly depends on the donor-acceptor relationships in nature, which are determined by the plants’ hereditary characteristics, the growth phase, location and vegetation conditions. The most active CO2 molecules assimilation from the air is the plants flag leaf, on which the main fruit load falls. During the caryopsis formation period, in photosynthesis intensity terms, it exceeded the pre-flag leaf by an average of 1.5 times, and the lower one by 2.7 times. In special model field experiments, it was found that its removal from plants leads to an increase in the pre-flag leaf photosynthesis intensity by an average of 35.4%, and the third from the top - by 28.0%. When the flag leaf remains alone, and the rest are removed, its CO2 assimilation intensity increases only by 5.6%. It was concluded that the spring wheat genetic resources are characterized by a plant leaves photosynthesis intensity sufficiently wide polymorphism to effectively select forms with a photosynthesis high activity and purposefully use inbreeding. Work in this direction may well be successful since the leaves photosynthesis intensity in culture plants is high hereditary conditioning.

Authors: Varavkin V A 
Published: October 2021

Abstract
The effect of high temperatures on the xeromorphism of leaves and the water-holding capacity of various ecotypes tissues of winter wheat has been studied. In the weather conditions of 2013 in the forest-steppe zone, according to the xeromorphism of the flag leaf structure, a significant variation in the number of stomata in the studied wheat varieties was revealed. Significant differences were noted in winter wheat varieties in the number of stomata at the beginning of earing and flowering, with the exception of the Gordovita and Sonechko varieties. An increase in the number of stomata per leaf area unit corresponds to a smaller cell size, that is, an increase in xeromorphism. Varieties Natalka, Rozkishna, Sonechko, Bilitsya are characterized by the highest xeromorphism and by a high adaptive potential in the agro-climatic conditions of the forest-steppe zone. In the phase of the beginning of earing and flowering in the weather conditions of 2014, significant differences were defined between winter wheat varieties in the number of stomata on flag leaves. The exceptions for this indicator were Sonechko, Rozkishna, Gordovita, Pilipovka varieties. According to the parameter of the highest xeromorphism, the varieties Sonechko, Rozkishna, Gordovita were identified. This characterizes them as ecotypes with a high adaptive potential to arid conditions that arise when growing crops in a given zone. During the studies in 2013-2015 the varioust ability of winter wheat varieties to retain water, depending on their genetic characteristics and the duration of the action of the extreme environmental factor was identified. The varieties of winter wheat that have a higher water-holding capacity of tissues, after the impact on stress factor during 1.5 hours, include: Sonechko, Yuvilyar Mironivsky, Krasnodarskaya 99, in Memory of Craft.

Abstract
The paper states that study of the production process of winter wheat plants, including overwintering of plants. It showed that the plants treatment with biological products Albit and Moddus in the phase of 3-5 leaves had a positive effect on the studied parameters. The treatment with Albit increased the number of shoots and plant height, while Moddus increased the mass of plants and roots, the number of secondary roots and leaves, and the content of sugars and monosaccharides. The treatment with Moddus helped to preserve some overwintered plants by 6%, and Albit by 5% in comparison to untreated ones. The loss of sugars was insignificant, up to 5% for untreated plants, up to 4.6% when treated with Albit, and up to 3.8% when treated with Moddus. The sugar content in the tillering nodes was 16.2%, when treated with Albit was more by 10%. The sugar content in the tillering nodes was 16.2%, when treated with Moddus was by 21%, i.e., with an even more significant volume. The fully ripe grain had a high content of sugars and starch. The treatment with Albit promoted an increase in starch up to 16%, and with Moddus, an increase in sugars by 26%. The mass of a thousand grains and grain yield increased when treated with Albit and Moddus. The mass of 1000 seeds was equal to 2.5 g, the yield when treated with Albit by 16%, and it increased with Moddus by 20%.

Abstract
The northern Elbrus region is the Greater Caucasus most thoroughly studied sector. Here, in the Bolshoi Zelenchuk Baksan interfluve, the Caucasus pre-Alpine basement, represented by a granite-metamorphic layer, is visible. The interdisciplinary research information support is considered, which covers the Caucasus pre-Alpine development two competing concepts theoretical and methodological foundations - geosynclinals and new global tectonics. The article authors have identified geological objects that disprove a large thrust structures number presence. It is shown that the Russia Petrographic Code terminology, published in 1995, is not consistent with the Stratigraphic Code terminology (1977, 1992, 2006). This led to the synonyms and homonyms emergence. Following the PK-95 requirements in the explanatory note to the K-38-1 tablet map led to the SC logically justified and consistent with the instructions’ destruction, metamorphic formations stratigraphic schemes developed over 50 years.

Meanwhile, the main trends in the development of cities and the urban environment as a whole are indicated. The paper provides data on the pollution of water resources of the Krasnoyarsk Krai, caused, among other things, by the anthropogenic impact on the environment, and identifies environmental problems arising from the functioning and development of large urban agglomerations. In addition, the tasks and problems associated with the realization of environmental monitoring have been investigated, the prospects for its application in cities have been determined, and the tasks solvable by using data on the state of the natural urban environment, as well as areas close to the city and experiencing serious impacts due to the livelihood of the urban population, have been identified. Within the study, sufficient attention is paid to the issues of ensuring the purity of water resources used in urban agglomerations, the issues of environmental pollution caused by accumulations of waste of the urban population at urban landfills, as well as landfills positioned in areas adjacent to cities, the problems of changes in the landscape, soil, and vegetation cover in large cities. The issues of atmospheric air pollution in large urban agglomerations are also considered.
Mechanized complex of mine water purification from large mechanical impurities
Authors: Ovchinnikov N P 
Published: October 2021

Abstract
It is well known that the main reason for the failure of sectional pumps in underground mines is the extensive hydroabrasive wear of their impellers. The rate of hydroabrasive wear of the impellers of sectional pumps largely depends on the size of solid particles contained in mine waters. Within the framework of this research work, in order to reduce the rate of hydroabrasive wear of parts of the flow path of sectional pumps of mine drainage installations, in particular impellers, a mechanized complex was developed and sufficiently substantiated for cleaning mine water from large solid particles. It is based on the use of a hydrocyclone and a high-frequency screen. Introduction of the developed technical solution in mine drainage systems will reduce the intensity of hydroabrasive wear of sectional pump impellers.

Abstract
In the Russian Federation, the main gas reserves are located in Siberia, and they are also present in the North Caucasus and the Black Sea basin. The largest gas fields in Russia are in harsh climatic conditions and drilling remains the main method of their development. Prior to its use, a preliminary study of rocks is required. Safety rules in the oil and gas industry are always relevant, taking into account, as a rule, harsh natural and climatic conditions in promising gas production regions. The forecasts for the growth of Russia’s gas industry varied greatly depending on the overall future prospects for the development of the country’s economic situation. This would entail examining the risks posed by the combined effects of natural and man-made factors on the environment and human health in areas affected by the gas industry. The most effective and widespread method of gas production, but at the same time the most traumatic of the articles is drilling. The article presents the main reasons for the injury of workers during drilling operations: technical, sanitary, organizational and psychological. Based on the causes of injuries in the performance of brown work, the authors developed and presented in the article a number of measures aimed at the pre-rotation or reduction of the impact of dangerous and harmful factors on workers when drilling gas wells. Gas mixtures of explosions and fire hazards, as well as when inhaled, can lead to poisoning of workers or an emergency. The development of a list of measures to protect against peacetime emergencies for gas facilities is presented in the second part of the work in the form of organizational and engineering measures. The list of measures for protection in peacetime emergencies for gas facilities is aimed at ensuring industrial safety, emergency resistance of hazardous production facilities, creating safe working conditions during drilling operations.

Published: October 2021

Abstract
The purpose of our work is to analyze the results of monitoring agricultural landscapes exposed to wind erosion and develop recommendations for their protection and further use, depending on their quality condition. Monitoring data allows us to assess the state of agricultural land and make recommendations for their further use. During the research, modern methods of territory survey were used, such as remote sensing of the earth using satellite images and unmanned aerial vehicles, as well as ground - based methods for detecting deflated land. Deflated areas of agricultural landscapes were identified, the area, the degree of their degradation, the causes of their occurrence and the percentage of increase in the area relative to previous surveys were determined. The results of monitoring of agricultural landscapes show that the area of land subject to wind erosion tends to increase, and in addition, there is an increase in the area of land with a medium, strong and very strong degree of degradation. The obtained research results give an idea of the current state of agricultural landscapes that have undergone deflation, and also allow us to propose a number of measures aimed at their improvement and preservation. It should also be noted that not taking urgent measures to correct the current situation will lead to the loss of large areas of agricultural land in all administrative districts of the region.

Published: October 2021

Abstract
The paper is devoted to the study of the use of organic-mineral waste from the pulp and paper industry for the land and dumps restoration disturbed by the mining and processing industry. The examination of the chemical, agrochemical and toxicological properties of the dumps of the Verninsky GOK were carried out. It showed their toxicity to the environment and the need for restoration. It is proposed to use soil moisture obtained from frozen colloidal sediments of sludge-lignin of the Baikal PPM OJSC (BPPM) to intensify the restoration succession. It reduces the toxic effect of dumps on higher plants and introduces the necessary nutrients. At the same time, the use of the obtained soil moistures will make it possible not only to restore lands disturbed by the mining and processing industry, but also to utilize the accumulated waste of JSC BPPM, which creates a huge socio-ecological threat for Lake Baikal and the entire Southern Baikal region.
