Authors: Khakimova G V , Asfandiyarova L R 
Published: September 2021

Abstract
Snow cover monitoring is a part of the environmental monitoring system, the pollution of which is a reflection of the degree of anthropogenic impact in view of the fact that the snow cover is an effective accumulator of aerosol pollutants falling out of the atmospheric air. Carrying out a complete study of atmospheric air, scientific assessment of the dynamics of the state of urban air and computer modeling is not possible without analysis and statistical processing of the data obtained using special software. This article is an example of the use of GIS technologies in order to visualize and interpret the results obtained in the analysis of the snow cover of an industrial city (in case of the Sterlitamak city), in particular, the Kriging method used makes it possible to obtain representative schematic maps of urban pollution.
Modern climate changes and dynamics of density and structure of bird population of South Baikal of forest ecosystems in winter period
Authors: Mel’nikov Yu 
Published: September 2021

Abstract
On the basis long-term researches (2010-2021), the features of the formation of the winter population of birds on the right bank of the source of the Angara river (South Baikal) during a period of sharp climate warming are considered. It is shown that the warming was accompanied by a gradual decrease in the total density of the bird population and a noticeable increase in their species diversity. On the key site, were 73 wintering species recorded, of which 28 were new to the region. However, 24 species were previously in this area as nesting, migratory and summering birds found. Only 4 species were really new. All new wintering species differed in insignificant numbers and the increase in the number of wintering species was due to an increase in the comfort of the living conditions of birds as result of climate warming. The relationship between population density birds and the number of wintering species was clearly in certain categories manifested, and only in minor species did it play a certain role in increasing their population density. The reformation of the structure of the bird population in the winter period due to the noticeable warming of the climate was almost completely by the dynamics of the population of the most massive and numerous species of sedentary and migrating for wintering species determined. The decrease in the abundance of birds is clearly associated with a shift in the optima of their ranges to more northern regions.

AbstractA study of the hydrophysical properties of substrates of technogenic landscapes, an assessment of the prospects of using thermoactivated vermiculite as an ameliorant was carried out. Contaminated areas are characterized by the absence of vegetation and a low probability of initiating the process of soil formation without direct intervention. Thermally activated vermiculite has been proposed as an ameliorant to improve the quality of soil and reduce the geochemical mobility of metals. The proposed materials have water-retaining properties, high sorption activity with respect to a number of metals, developed specific surface area and availability in sufficient quantities. The use of local mining enterprises as remediators of waste makes it possible to increase the profitability of developments and helps to reduce the volume of accumulated waste.

Published: September 2021

Abstract
Since 2003, the State Agrarian University of the Northern Trans-Urals has been conducting research on the cultivation of healthy seed tubers of the Vesna variety from botanical seeds. It was found that under the conditions of the northern forest-steppe of the Tyumen region, the marked variety for many years forms berries on plants. After ripening, the seeds washed from them after one to two years of storage have a high germination capacity. When sown in a greenhouse, they produce minitubers, and the next year, normal tubers. Their further reproduction in isolated areas of the taiga zone and the tundra zone makes it possible to obtain healthy seed tubers in the required volume for sale to amateur gardeners and small farms.

Abstract
The paper presents research on the study of spring soft wheat cultivars from the genetic fund of the Federal Research Center of the All-Russian Institute of Plant Genetic Resources named after N. I. Vavilov (VIR). In the course of the research work, the influence of agroclimatic conditions on the yield of different varieties with different genotypic characteristics was studied. Two varieties with the highest yield were selected: Arhat by 18.2 % and Icarus by 17.82 %. Studies have shown low plasticity of the studied varieties due to the strong variability of yield. According to the analysis of the research results, it was found that the spring soft wheat variety Liza (Russia) had the lowest degree of variability (V=5.68 %). It was revealed that as a result of four years of research, all the samples studied in the experiment have a complete correlation between the yield and the weather conditions of the growing season.

Published: September 2021

Abstract
The article considers the biodiversity and spatial structure of the urban flora as a complex phenomenon formed as a result of the interaction of natural and anthropogenic ecosystems. The data of the chorological analysis of the urban flora demonstrate the genesis of the species diversity and the relationship with other botanical and geographical areas, while being of great importance in predicting the ways of its formation. The purpose of this research was to study and analyze the spatial distribution of the flora species composition of Sosnovoborsk (south of Central Siberia, Krasnoyarsk Territory). The study of plant biodiversity was carried out using a special research method of urbanized territories - the model allocation method in combination with traditional route surveys. The types of areas and their elements were determined using the literature data of fundamental floristic and monographic summaries. In the course of the analysis, the types of areas identified by other authors studying the floras of various Siberian regions were taken as a basis. As a result of the study, 387 species of vascular plants were determined, distributed in 231 genera and 62 families. The chorological analysis showed the dominance of Eurasian and Euro-Siberian geographical elements, as well as the belonging of the flora of Sosnovoborsk to the subboreal type, formed on the basis of forest-steppe with a high activity of boreal species.

Abstract
The consequences of increasing urbanization in the modern world are in the field of knowledge of a wide variety of sciences, while one of the most important aspects of this problem is monitoring the biological diversity of urban areas, as the main condition for their sustainable ecological development. The study of urban flora is one of the priority areas of modern floristry and phytogeography, the scientific value of which is steadily increasing due to the strengthening, both in time and in space, of anthropogenic pressure. The purpose of the article is to identify plant species for the Red List of Threatened Animals and Plants of the Krasnoyarsk Territory in the urbanized landscape of the city of Krasnoyarsk and to determine their status. As a result of the study, 56 species of protected plants in Krasnoyarsk were identified, proposed for protection in the new edition of the regional Red List of Threatened Animals and Plants of 2022. A list of Red List of Threatened Animals and Plants species was compiled indicating the main habitats and distribution in 26 established and studied model sites within the city. For each species, Latin and Russian names, main habitats, frequency of occurrence and abundance are given, in the case of authors’ own collections. The statuses of rare species of Krasnoyarsk have been determined: 1 species has an indefinite status - 4 (I); 28 species have the status 3 (R) - rare species; 25 species have status 2 (V) - vulnerable species, 2 species with status 1 (E) - endangered species.

Published: September 2021

Abstract
The research is devoted to studying the biological productivity of modal Siberian pine stands of the Siberian taiga zone (southern ecoregions). Forest stands of the IV bonitet class, including Bilberry- and Bergenia-dominated forest types, were studied. The study was based on mathematical modeling of the forest stand growth combined with the conversion-volumetric method for determining the amount of phytomass converted to sequestered carbon. Tables were proposed that reflect the quantitative characteristics of the age dynamics in phytomass and the carbon contained in it. The range of changes in the phytomass in modal Siberian pine stands throughout all age classes in the Bilberry-dominated forest type was from 40.2 to 297.7 t m−3, in the Bergenia-dominated forest type - from 52.6 to 292.1 t m−3. In Siberian pine forests of the IV bonitet class, carbon pools were concentrated in the Bilberry-dominated type from 37.5 to 147.6 t⋅C⋅ha−1, in the Bergenia-dominated type - from 48.1 to 147.2 t⋅C⋅ha−1. The results supplemented the existing database on the biological productivity of taiga forests and can be used in organizing forest monitoring and implementing regional environmental programs, including calculating the carbon cycle.
Some cenotic features of Scots pine blister rust and red ring rot in pine forests

Published: September 2021

Abstract
Scots pine blister rust and red ring rot are common diseases on Scots pine throughout its entire range. Many specialists have studied these diseases in various aspects. Nevertheless, the cenotic patterns of incidence in pine forests, primarily for Scots pine blister rust, have been studied to a lesser extent. The study is aimed to establish the peculiarities of incidence of Scots pine blister rust and red ring rot in pine forests at the dendrocenosis-level in the context of forest conditions and the biology of pathogens. We studied the pine forests of the Dzerzhinskoe forestry located in the Krasnoyarsk Krai. Research methods included detailed forest pathological examination, macroscopic diagnostics of diseases, determination of indicators proving disease manifestation, and analysis of the series of diameter-related distribution of trees. Scots pine blister rust was proved to be of high injuriousness for trees and entire forest stand in case of hotspot emergency. Red ring rot does not play such a significant role in the plant community since trees with signs of rot retain their activity for a long time as part of the cenopopulation. Diameter-related distribution of the affected trees mainly corresponds to the general stand structure. Nevertheless, in red ring rot hotspots, there is a certain predominance of large specimens in the affected part of the stand, which is associated with a reduced immunity in such trees. Scots pine blister rust in herb-rich pine forests often damages trees with diameters below average. Scots pine blister rust pathogen completes different stages of its life cycle on different plants infecting intermediate host from various species of herbaceous growing in the ground cover of herb-rich pine forests.

Authors: Tsybulevsky V V , Maslov G G , Tazmeev B K 
Published: September 2021

Abstract
A modernized Harrington function with three zones of evaluation indicators is proposed: excellent-good-satisfactory for making a decision on choosing the best design of a combine harvester. Harrington’s desirability function is used only in the 0.2 … 0.8 section, in the interval of which the system of j-th estimated indicators with its own units of measurement (operating costs, grain losses, labor costs, energy consumption of the combine harvesting process) is located. The developed desirability scales were used based on economic tests of combines. Dependences are obtained for converting the values of experimental estimated indicators to a dimensionless scale limited by the range of the desirability function 0.2 … 0.8. By the method of paired comparison of the estimated indicators, their rank place, the weight coefficient of each indicator used in calculating the generalized criterion for the comprehensive assessment of each combine harvester was determined. The maximum value of the criterion determines the best design of the combine from the alternative. The values of the

criteria for the integrated assessment of combines with and without weight factors (mean geometric value of the criteria) have been analysed. When using the latter, a more significant difference was obtained between the compared designs of combines. Such a comparison can be applied to carry out comparative tests of combines under the same conditions (yield, moisture, weediness, etc.). The purpose of the work is to substantiate, using the example of a group of compared grain harvesters, the best design option using the proposed system of evaluation indicators and generalized criteria for complex evaluation.

Published: September 2021

Abstract
The scheme of all-around (triaxial) compression of the deformable material in the deformation center is the most favorable and desirable scheme from the point of view of giving the material high values of its physical and mechanical properties. The intention to bring real technological processes closer to implementation of this scheme led to development of range of technologies for processing meterials with a high-pressure fluid and, in particular, hydroextrusion of materials. The hydroextrusion process in the most comprehensive way meets the requirement of all-around compression scheme of material when it this material is compressed in the hydrodynamic friction mode, which stable nature of flow depends on flow rate of a working fluid entering through the annular clearance between the plunger and the chamber. The flow rate is determined by pressure differential and the parameters of the clearance itself. Therefore, there is a need for analytical study of clearance parameters for various hydraulic extrusion schemes. This article analyzes the work motion pattern of an uncompacted plunger in a solid container and for hydroextrusion with an uncompressed shank. For these hydroextrusion schemes the mathematical equations are proposed in order to determine the parameters of the clearance, taking into account the elastic deformations of the container and the plunger (shank).

Development of a manual garden shovel with the ability to quickly clean the working surface
Authors: Voiku I P 
Published: September 2021

Abstract
Manual garden shovels have various shapes and sizes, are used to perform a large number of works with soil. A common problem for all garden shovels is the sticking of soil on the working part – the blade. Constant sticking of soil on the blade reduces labor productivity, requires considerable effort and time for cleaning, even the presence of special devices. There are constant attempts to solve the problem of quick cleaning of the blade of manual shovels. Many technical solutions to this problem are patented and are actively used in practice. The design of the self-cleaning shovel consists of a handle and a metal blade with a sharpened cutting edge fixed at one end of the handle, a tubular clamp and footrests, as well as a cleaning plate that is fixed to the movable handle, and a compression spring located under the movable handle around the tubular clamp of the shovel. Cleaning of a metal blade is performed by the cleaning plate, which moves along the metal blade from the footrests to the cutting edge and back. To do this, the user moves the movable handle towards the metal blade, providing compression of the spring.
