Authors: Tatarnikova N A 
Published: January 2020

Abstract
In diseases caused by Chl psittaci, a hematogenic type of infection is often observed, accompanied by damage to the CNS and internal organs: liver, spleen, lung. Lymphogenic spread of chlamydia (Chl trachomatis, venereal lymphogranulematosis) is possible. The hematogenic pathway of infection is most frequently observed in Chl trachomatis diseases (serovars D and K). Different biological variants (subspecies) of chlamydia cause lesions of different organs and systems. Chl trachomatis causes conjunctivitis, locally affects the mucous eye and urogenital tract.
Improving the efficiency of technological measurements when monitoring production and environmental indicators of thermal power plants
Authors: Tynchenko Ya A , Kovalev I V 
Published: January 2020

Abstract
The approaches are considered that provide an increase in the efficiency of technological measurements when monitoring production and environmental indicators of thermal power plants. The experience of expert evaluation of gas analytical systems is analyzed taking into account the technological parameters of equipment used in production processes at thermal power plants. The need for expert assessment is justified by the fact that currently there are no universal (generalized) formulas expressing the dependence of production and environmental parameters on each other or on the parameters of the technological process at thermal power plants. As practice shows, such dependencies are determined experimentally and most often with the involvement of specialists from commissioning organizations.

Published: January 2020

Abstract
The article assesses the dynamics of desertification based on changes in the area of moving sands in the territories of the villages Issatay, Zineden, Maykomgen, Miyaly Zhaskairat over the past 17 years based on the processed data of remote sensing satellite images. It should be noted that the research area is located almost on the border of the semi-desert and desert zones, which within Kazakhstan occupy 57.7% of the territory. Ecosystems of these arid territories are very vulnerable to impacts, especially in modern conditions of climate change, reduction of water resources and active anthropogenic development. It should be noted that land degradation has a serious socio-economic impact on the standard of living and health of the population, especially on socially vulnerable sections of the rural population.

Published: January 2020

Abstract
The article presents data on the chemical composition of the powder from sprouted wheat pomace, which determines its high nutritional value: dietary fiber (45%), vitamins, mg / 100g (C - 450, P-active substances 390), minor components, mg / 100g (flavonoids 690, chlorophyll 41, tannins 1310) and minerals, mg / 100g (calcium 60, magnesium 85, phosphorus 300, iron 6.8). The resulting powder is able to provide a daily physiological need for minor components from 41 to 1950%, for micro and macromineral substances from 6 to 48%. It also strengthens the functional significance of the main components in the composition of enriched products due to biologically active substances and dietary fiber. Titrimetric, photometric, and spectrophotometric standardized methods were used in the study of the powder chemical composition and the quality indicators of the composite flour mixture. The composition is justified. A rational ratio of wheat, hemp flour, and powder from sprouted wheat pomace - 70:20:10 respectively is determined, based on the results of organoleptic and physico-chemical indicators. The study revealed increased nutritional value compared to wheat flour. The developed composite flour mixture is able to meet 40 % of physiological norm in terms of nutrients and more than 5000% in selenium; it can be considered as an alternative to wheat flour for the development of enriched food products.
Simulation of agricultural landscape catenas based on the analysis of hydrodynamic characteristics of the underlying surfaces of slope lands
Authors: Vasiliev S A 
Published: January 2020

Abstract
The agricultural landscape of slope lands is characterized by ecological instability and to ensure its equilibrium state a system of agronomic, melioration and environmental measures is carried out. Assessing the state of slope agricultural landscapes, it is necessary to take into account slope parameters, contour sizes, hydrological regime, types and varieties of soils, erosion processes, economic conditions, location, etc. Monitoring the above parameters will allow to detect hidden impacts or changes and restore the stability of the agricultural ecosystem early, for example, to maintain the hydrodynamic characteristics of the underlying surface for a certain period. Comprehensive research including methods of mathematical simulation and analysis carried out on the agricultural landscape catena is most effective. One of the fundamental scientific problems to be solved in this is to study and construct agricultural landscape catenas using the analysis of hydrodynamic characteristics of soil and vegetation cover of slope lands. It has been established that for compensatory melioration measures and engineering melioration systems planned on agricultural landscapes of slope lands, the following water flow rates occur: from 0.022 to 1.5 m/s for phytomelioration measures when slopes are rather steep; from 0.138 m/s for agricultural melioration measures at a slope of 0.08; and for traditional tillage rates exceed the critical ones and reach 0.8 m/s. According to the nomogram for determining the velocity diagram on a particular catchment slope, it is possible to assess and control anti-erosion melioration measures, revealing the actual speed regime of water flow in problem areas, and, therefore, it is possible to prevent erosion processes and preserve soil fertility on meliorated slope lands early.

Authors: Zaitsev A M , Solodun V I , Gorbunova M S 
Published: January 2020

AbstractThe studies were carried out with the aim of identifying the most effective method for sowing spring wheat for the Pre-Baikal region through a comparative study of sowing machines of domestic and foreign production with different types of openers according to the backgrounds of dump, non-dump and zero tillage. The research was carried out on the basis of advanced farms in the Irkutsk region, widely using modern sowing units in 2016-2018 on typical gray forest loamy soils. In experiments, in comparison with the SZ-3,6 seeder, the Case IH Concord 2000, John Deere 1830, Morris Concept 2000, Tom-10 sowing complexes were studied, providing strip-spread, tape, single-line sowing with paw, anchor and disk coulters. As a result, it was found that the application of the band-spread method of sowing with the Concord 2000, John Deere 1830, Morris Concept 2000 sowing complexes increases the field germination of spring wheat seeds by 10-20%, plant standing density by 34-42%, and yield by 0.38- 0.47 t/ha. An increase in the depth of seed placement to 5-6 cm led to an increase in the yield of wheat by 0.16 t/ha when sowing SZ-3.6; 0.26 t/ha when sowing John Deere 1830; 0.23 t/ha when sowing Concord 2000. In the pre-Baikal agricultural sector, to increase the yield of grain crops, it is advisable instead of the ordinary method of sowing with the SZ-3.6 seeders to apply the tape and strip-spread methods of sowing with the paw and anchor coulters both for dump and for subsurface processing and for direct sowing. The most promising sowing machines are the sowing complexes Concord 2000, John Deere 1830, Morris Concept 2000 and their domestic counterparts Kuzbass-8.5.

Published: January 2020

Abstract
In the steppe zone, the productivity of spring rape for green fodder was studied in single-species and poly-species crops with annual bluegrass and leguminous crops. It was established that single-species crops have high productivity; but they are characterized by low adaptive ability. Thus, their productivity in the steppe zone of Tuva depends on weather conditions. It was determined that in the crops of spring rape with peas, reliable increases in the yield of green mass were obtained. The economic efficiency of spring rape cultivation in two-component crops on the territory of Tuva republic is determined.

Published: January 2020

Abstract
Forest fire represents one of the most serious abiotic stress factors that influence the function and productivity of ecosystems globally. Siberian pine forests are often exposed to forest fires but they are not always harmful to them. We have analyzed the effects of repeated heat stress on the photosynthetic apparatus of Scotch pines before and after surface fire exposure that occurred in the growing season in 2014. The survey area was the forest steppe zone of Krasnoyarsk region (South Siberia). First, we investigated the changes in the temperature-dependent responses of photosynthesis in the needles by means of fast and delayed chlorophyll fluorescence. Our results are indicative of some acclimation of Scotch pines after fire to the repeated high temperature stress. Also, this paper discusses the possibility of using chlorophyll fluorescence parameters for evaluating the presence of physiological changes after the fire affects. The time after fire effect and growth season were found to be important to assess the repair of photosynthesis and pigment content.

Abstract
Currently great attention is paid around the world to the problem of protecting the biosphere and the rational use of biological resources. The issues of protection of the atmosphere, water sources, flora and fauna, soil cover are becoming increasingly acute. Research is underway to develop the most rational principles for organizing industrial production that exclude environmental pollution. Particularly noteworthy are the issues of protection and rational use of soil cover. In the entire history of the development of human society, it has lost 20 million km2 of land resources. Currently, the loss of land on the planet for agricultural use is 5-7 million hectares annually. These lands go for building settlements on them, laying roads, mining, are lost due to erosion and salinization, the creation of industrial complexes, reservoirs, etc. Scientists estimate that the world’s population is growing by 68–70 million people every year, population growth and its increase is associated with the solution of major national and international problems, and this is the focus of the work.

Authors: Fazullin D D , Fazylova R D 
Published: January 2020

Abstract
To reduce the concentration of heavy metal ions in drinking, natural and wastewater to the established standards, a dynamic membrane with a surface layer of cellulose acetate particles on a nylon substrate was obtained. A dynamic membrane layer was formed from cellulose acetate particles with sizes from 42 to 130 nm. The cellulose acetate content was 14 % by weight, upon receipt from a 10 % solution of cellulose acetate in acetone. After applying a layer of cellulose acetate to the surface of a nylon substrate, a decrease in the specific productivity of the membranes is observed more than 10 times due to the formation of a dynamic layer on the surface and in the pores of the substrate. During the operation of the membrane for 1 hour, there is a decrease in the specific productivity of the membrane by 1.5 times and an increase in the working pressure from 0.35 to 0.41 MPa by 1.2 times. A high selectivity of the dynamic nylon-ACd membrane with respect to iron ions 96%, copper 93% and chromium 93% was established with a specific productivity of 300 dm3/m2·h and a pressure of 0.4 MPa. After purification of tap water with a dynamic membrane, the concentration of heavy metal ions does not exceed the MPC for water bodies for drinking water.

Published: January 2020

Abstract
The problem of creating a geographic spatial database of morphometric indicators based on the basin approach for several rivers in the Krasnoyarsk region is considered. The division of the territory into catchment basins is carried out in a hierarchical system, up to the river tributaries of the 4-th order. The initial data for the construction of watersheds was a MERIT DEM Hydro digital relief model, vector data on the hydrographic network from A.P. Karpinsky All-Russian Research Geological Institute (VSEGEI) and Roscartography (Federal Agency of Geodesy and Cartography). In the process of data processing methods and algorithms of spatial analysis of relief and hydrological modeling, implemented in GIS software Whitebox GAT, QGIS and ArcGIS, were used. The main morphometric characteristics of the relief are calculated: slope, exposure of slopes; with the help of zone statistics for basins, the average values of these characteristics, the main statistics are calculated. We consider this work as the first stage in the creation of information support for the tasks of land use analysis, assessment of the natural resource potential of the region.

Authors: Litsukov S D , Akinchin A V , Linkov S A , Shiryaev A V , Kuznetsova L N 
Published: January 2020

Abstract
The article presents agrochemical techniques that reduce the accumulation of heavy metals in vegetable crops, such as potatoes and table beets, when they are cultivated on typical chernozem soils with a heavy loam granulometric composition. The data obtained allowed to conclude that the use of lime, as well as the simultaneous use of lime and manure, reduce the penetration of cadmium in potato tubers by 22 and 18%, respectively. In addition, the use of organic in its pure form reduces the penetration of this element by 8%. The studied cultures absorbed copper, lead and zinc in amounts not exceeding the threshold limit value (TLV), also in plots artificially contaminated with these metals. Heavy metals are more intensely absorbed by the aerial part of potato. During the experiments, it was found that the use of lime, organics, as well as their simultaneous application contributed to a decrease in the studied elements penetration into table beet plants. The increase in the dose of mineral fertilizers doubled positive effect of lower penetration of copper and lead into plants, although the difference was within the experimental error. A double dose of mineral fertilizer did not have any positive effect on the penetration of cadmium and zinc.

Published: January 2020

Abstract
The article presents the results of a study of annual shoots of large-fruited apple varieties, characterized by early ripening and consumer maturity, in the Botanical Garden named after Vs. M. Krutovsky. The leaf area, weight of 1 cm2 of leaf and 1 running centimeter of shoot in absolutely dry state are calculated. A significant positive correlation was revealed between the indicators of the area of the sheet and the mass of 1 cm2 of sheet in absolutely dry state, and between the mass of 1 linear cm shoot and 1 cm2 leaf. Using the regression method, it is possible to reduce labor costs for determining phytomass without resorting to additional measurements of the supply of dry foliage mass and to determine the increase in the mass of branches even in leafless periods. In Siberia, it is recommended to use the most promising varieties of apple trees in terms of photosynthetic activity and productivity for cultivation.
