Authors: Letuta U G , Tikhonova T A 
Published: January 2020

Abstract
Magnetic isotope effects of magnesium 25Mg on antibiotic resistance and biofilm formation of bacteria E. coli were discovered. The increase in antibiotic resistance in the presence of the ion 25Mg2+ was registered for E. coli cells incubated with quinolones, indicating the inhibiting effect of the magnetic moments of nuclei 25Mg on deoxyribonucleic acid (DNA) synthesis. It was discovered that the process of biofilm formation by the bacteria E. coli is magnetosensitive. Magnetic magnesium isotope presence in nutrient media stimulated formation of biofilm compared with nonmagnetic isotopes 24, 26Mg. As e result the enrichment of media by magnetic magnesium can be used to control the physiological properties of bacteria: biofilm formation and antibiotic resistance.

Published: January 2020

Abstract
Forest ecosystems play a global role in carbon sequestration and emission processes on a planetary scale. The topic of the functional ecological role of forests is urgent due to the problem of climate warming and an increase in the level of carbon dioxide concentration in the atmosphere. Currently, a differentiated (regional) approach to assessing the biological productivity of stands and their carbon-removing ability is important, which allows a detailed approach to organizing monitoring of the ecological balance and using the resource potential of forest ecosystems of a certain territory. The aim of this work was to assess the carbon-removing ability of modal stands of Siberian fir based on the study of the dynamics of the fractional composition of phytomass in the process of planting development. The studies were conducted in the conditions of the Central Siberian subtaiga forest-steppe region of the Krasnoyarsk Territory (the territory of the Bolshemurtinsky forestry). The object of research was fir stands of the third class bonitet. In the work, materials were used for eye-tracking taxation of 456 sections. The dynamics of the fractional composition was calculated using the conversion-volumetric method (Ph/M conversion) on the basis of the developed table of the growth course, followed by the conversion of the studied fir plantations to the carbon reserves deposited by the tree layer.

Published: January 2020

Abstract
The purpose of the work is to conduct a comparative assessment of the amount of smelted plant residues in various field crop rotations in the conditions of the Mari El Republic. The work was completed in 2013-2018 on a stationary site in a two-factor experiment. The first factor is types of crop rotation and crop rotation. Four crop rotation with a different set of crops. Cereal crops occupy 83% in the first. The share of cereals was 67% in the second and third. Cereals occupy 50% and perennial grasses and potatoes 50% in the fourth crop rotation. The second factor is mineral fertilizers: 1) without fertilizers: 2) N60P60K60. On average, 3.02 ± 0.06 t / ha of stubble and root residues was received per year according to the results of studies in the control grain-grass crop rotation with a one-year use of clover. There are no perennial herbs, but there are potatoes in the first fruit-bearing. Here, plant residues entered the soil by 41% less than in the first crop rotation. The accumulation of stubble and root residues was 2.91 ± 0.07 t / ha in the second crop rotation. The decrease is due to the cultivation of potatoes, which does not leave plant residues after harvesting. The largest number of stubble and root residues was formed in the third crop rotation (3.37 ± 0.07 t / ha). The use of mineral fertilizers increased the mass of stubble and root residues in all crop rotations by 0.16 t/ha.

Published: January 2020

Abstract
With transition to market economy for the majority of agroformations there was a problem which level of development does not correspond to its theoretical and practical importance in relation to modern conditions, it is a problem of efficiency of expenses for production of agricultural production in borders of separate rural territories. In the conditions when the formation of prices for products occurs according to the laws of the global market, the economic efficiency of its production is determined primarily by the specific production costs. The latter are caused not only by soil and climatic potential of economic entities, but also to a large extent by their geographical location and economic conditions. In other words, the cost and profitability of agricultural products vary in individual rural areas, not only in accordance with the yield, but also depending on the factors of “location” of producers, which, in turn, under the influence of the same natural conditions.

Published: January 2020

Abstract
The article presents the results of studying the chemical composition of the leaves of blue honeysuckle, naturally growing in the southern taiga of the Krasnoyarsk Territory. It was found that along with fiber and lignin, the studied biomass contains a significant amount (about 70 wt. %) of extractive substances. Using fractional extraction with solvents of increasing polarity, it was possible to extract from the studied raw materials 9.5 wt.% of substances soluble in non-polar solvents and about 60 wt.% of compounds soluble in isopropanol and water. A spectrophotometric study showed the presence in the leaves of blue honeysuckle (Lonicera caerulea L.) such classes of biologically active compounds that provide a wide range of pharmacological action of the plant, such as chlorophyll-containing derivatives, a complex of bioflavonoids, carbohydrate components, anthocyanins, tannins, organic acids and others. This circumstance opens up broad prospects for the practical usage of the biomass under study in the production of food additives, pharmaceutical and perfumery and cosmetic preparations.

The analysis of earthquake precursors in variations of TEC in the ionosphere and the subsequent impact on the environment
Authors: Denisenko A , Zeng Z 
Published: January 2020

Abstract
Ionospheric storms are general perturbations of the upper atmosphere which affect space- and ground-based technological systems. These storms are triggered by an increased flux of energetic electrons that are released by the Sun. Extreme solar activity may originate from Coronal Mass Ejections (CME) and solar flares that may result in ionospheric storms. The ionospheric anomalies usually happen in D-layer, E-layer and F-layer. They may be observed from 1 to 10 days prior to the earthquake and stay until 1 to 2 days after the earthquake. Comparatively the ionospheric precursors, the geomagnetic indices Dst, Kp and AE-indexes have been selected for pre-earthquake disturbed states. In the present study we are taking into account the existence of correlational changes in the ionosphere before strong earthquakes triggered by geomagnetic storms and we consider the subsequent impact on the environment. The statistical analysis presents the ionospheric precursors during geomagnetic storm conditions which occurred during March 2018 and correlated with them strong earthquakes.

Published: January 2020

Abstract
The possibility of applying the principles of organic farming in the cultivation of spring rape is considered in the article. The adoption of the Federal law “On organic products and on amendments to certain legislative acts of the Russian Federation” contributed to the creation of an effective mechanism for the production and sale of organic products in accordance with international standards and the orientation of the export potential of culture not only to the APEC countries, but also to the EU countries. Based on the analysis of the existing legislation in the field of organic production of agricultural crops and the used technologies, as well as taking into account the requirements for organic production and products, production and auxiliary processes of organic agricultural production in the cultivation of spring rape were developed. The agrotechnological plan of spring rape cultivation on organic technology in the conditions of Krasnoyarsk territory was developed, and then technological maps of production of oilseeds on traditional technology and organic were developed. The comparative evaluation of two technologies was carried out; economic indicators of efficiency are calculated. The calculations showed that due to the increase in the number of seeding-down treatments, the cost of production by organic technology is 8.4% higher than in technologies with the use of chemical means of protection. Due to the high selling price, which is more by 14.9 %, the profitability of rapeseed production by organic technology increased by 16% compared to traditional.
The determination of the rate of heat release in the diesel cylinder taking into account the change in the composition of the working substance

Published: January 2020

Abstract
The thermodynamic efficiency of the cycle of the internal combustion engine and its efficiency are related to the law of supply of heat to the working fluid. The characteristics of heat release allow us to evaluate and improve the combustion process from the point of view of the thermodynamic efficiency of the cycle, from thermodynamic positions. To optimize the combustion process in compression-ignition engines, including when working on unconventional fuels, it is necessary to develop an algorithm for determining the rate of heat release, taking into account the current composition of the working fluid, since when working on fuels with a changed chemical composition, the ratio of gases in the combustion products can significantly change. The type of heat dissipation characteristic is determined by the regularities of the combustion of fuel in the cylinder e and the law of displacement of the piston and depends, inter alia, on the composition of the working fluid, which continuously changes during combustion of diesel fuel, increasing volume and mass. Existing methods for calculating the heat dissipation characteristics consider a working body consisting of two components - a fresh charge and combustion products. Such an approach reduces the accuracy of calculations when determining the heat input from the diesel fuel indicator chart operating on fuels with modified chemical composition or on non-traditional fuels, since it does not take into account the change in the heat capacity and internal energy of the combustion products. In this article, a mathematical model to compute the heat dissipation in the cylinder of a diesel engine when operating on diesel fuel for the changes in the working fluid composition. The presented results of calculations for a diesel engine of 2CH10.5/12.0 when operating on diesel fuel at the nominal operating mode correspond to the results of the determination of the integral and differential heat dissipation rate obtained by the well known CNIDI method.

Abstract
The article discusses the results of hydrochemical and microbiological studies of the waters of the small river Arguzikha, the left-bank tributary of the Amur River. The natural landscapes of the Zeya-Bureya plain, along the territory of which a small river flows, are transformed into agrolandscapes. Organic matter, nitrogen and phosphorus compounds accumulated in the waters of the Arguzikha river. The number of heterotrophic bacteria, the main function of which is the destruction of organic matter, in the summer reached 75 thousand cells / ml, which corresponded to the dirty water quality class. The content of nitrogen compounds in water and the number of ammonium-oxidizing bacteria experienced seasonal dynamics. The obtained results of the study of hydrochemical and microbiological indicators of aquatic ecosystems of the Zeya-Bureya plain are the basis for further study of the technogenic load on small rivers of the agrolandscape.
Mathematical modeling of the interaction of magnetic fields of red blood cells
Authors: Kopyltsov A V 
Published: January 2020

Abstract
The article discusses the movement of red blood cells along narrow capillaries with a diameter less than the diameter of the red blood cell. The erythrocyte membrane in the narrow capillary performs a tank-treating motion with a frequency reaching several tens of revolutions per second. Electric charges located on the surface of an erythrocyte move together with the erythrocyte membrane and create a magnetic field in the surrounding space. A two-dimensional model of the movement of red blood cells along narrow capillaries is developed. Various options were considered: either neighboring red blood cells rotate in one direction, or in different directions. With different options, different distributions of the magnetic field strength are obtained. Calculations of the magnetic field were carried out at various distances between red blood cells and the speed of rotation of the erythrocyte membrane. It was shown that at distances between red blood cells less than two capillary diameters, the influence of neighboring red blood cells can be neglected (the difference is less than 3%).
