Abstract
A statistical analysis of the incidence rate of various types of diseases in a population for different age groups was carried out: children (up to 14 years old inclusive), adolescents (15-17 years old), adults (18 years old and older), depending on environmental factors such as concentration of atmospheric impurities, as well as drinking water quality indicators. A dynamic autoregressive model for panel data was used to determine the quantitative dependence of the incidence rate in a population on environmental pollution factors. Panel data on population morbidity indicators, air pollution and the drinking water quality were built on the basis of official statistics for the districts of the Voronezh region and the city of Voronezh over a multi-year period. Considering that the incidence levels in the districts of the Voronezh region and in the city of Voronezh linearly depend on determining factors, linear dynamic models were constructed to describe the level of the disease classes recorded for the year, depending on the level of the corresponding disease classes for the previous year, as well as those registered for the analyzed year of concentrations of chemical impurities in the atmosphere or, accordingly, the values of drinking water quality indicators. As a result of the analysis, statistically significant quantitative dependences on the recorded factors of technogenic environmental pollution were obtained for certain classes of morbidity.

Abstract
The task of automation and increasing the efficiency of calculating the parameters of the rectifying column for the needs of chemical production is being solved. Rectification is one of the most time-consuming chemical-technological processes responsible for the separation of liquid mixtures into practically pure components, which differ in boiling points, by repeated evaporation of the liquid and vapor condensation. The possibility of separation of the liquid mixture into its constituent components by distillation is due to the fact that the composition of the vapor formed above the liquid mixture differs from the composition of the liquid mixture under the conditions of the equilibrium state of steam and liquid. To select the optimal working conditions, it is necessary to take into account the heat consumption, temperature and pressure of the heat carrier - heating steam and cooling water, as well as the necessary dimensions of the columns and connecting elements with it by heat exchangers. All these factors are interrelated and depend, in particular, on the temperature and state of aggregation of the mixture supplied for separation. When calculating the processes of rectification, the compositions of liquids are usually given in mass fractions or percent, and for practical calculation it is more convenient to use the compositions of liquids and steam, expressed in molar fractions or percent. The software being developed will automate the calculation of distillation plants, which will increase the calculation speed. In most existing installations, rectification is not clear. The resulting components of light and oil distillates do not correspond to the required fractional composition, overgrowth of fractions is observed, some of the heaviest fractions of light diesel oil products fall into the bottom of the column, into fuel oil. Therefore, much attention is paid to the study and analysis of the operation of distillation columns, improving the methods of their calculation. The software created as a result of the project will be used directly by technologists, chemists and professors.

Published: September 2020

Abstract
Experimental data on the dynamics of the most important agrophysical indicators of soil fertility which were obtained against the background of various fertilizer systems and predecessors in the development of degraded reclaimed lands that were withdrawn from circulation are presented. It has been shown that the rate of formation of a macrostructure that is valuable in production (0.25-10 mm) strongly depends on the amount of organic matter entering the soil in the form of high doses of all types of organic fertilizers, green manure and crop-root residues, upon decomposition of which an active humus is formed, which, when interacting with calcium, impregnates and cements the soil lumps, transforming them into a water-insoluble form. The greatest positive influence on the structural coefficient is exerted by cultivation of barley according to the organic background with the introduction of manure (40 … 80 t / ha) or liquid runoff of livestock complexes (120 t / ha) in combination with sowing application 10 kg a.v. P2O5 and 30 kg a.m. nitrogen as a top dressing per 1 ha. It has been established that in order to improve agrophysical parameters when degraded lands are involved in agricultural production, along with the introduction of high doses of organic fertilizers, crops with a deeply penetrating, powerfully developed root system that can not only condense the arable and plow layers, reduce acidity should be sown soil, but also at the same time improve its structure.

Published: September 2020

AbstractIn recent decades, in our country insufficient attention has been paid to the study of soil mechanics. Currently, there is a need to study the mechanical processes in the soil when it interacts with the working bodies of tillage machines and operating systems of mobile agricultural equipment. With existing technologies for cultivating crops, various machines pass through the field from 10 to 15 times. The tools used have a centuries-old history of development and improvement, both of individual types of working parts, and of technological tillage complexes as a whole. At the same time, the scientific basis for tillage has not yet been fully developed. The article explores soil mechanics and intensification of agriculture; saturating it with heavy machines, and increasing the energy saturation of tractors put forward new tasks that cannot be solved without the development of theoretical and applied research in the field of soil mechanics. Depending on the formulation of the tasks of the interaction of tillage organs and movers with soil, degenerate models can be used that contain only those rheological properties of the soil that define the main goal of the technological problem.

Abstract
The article presents the results of the study of structural-sorption performance and absorption properties of both raw materials and carbon sorbents obtained in the carbonization process, in terms of their ability to absorb petroleum products from water and contribute to the preservation of environmental infrastructure. Under the proposed mode of carbonization received hydrophobic sorbents. The analysis of the obtained results shows that carbon materials based on pine sawdust, obtained at a temperature of 300 °C for 8-10 minutes, have the best buoyancy – 97-100%. This can be explained by the fact that in the process of carbonization of cellulose-containing raw materials the last of the components of plant tissues decomposes lignin (active decomposition of lignin occurs in the temperature range 280-325 °C). As a result of research it is established that in the process of low-temperature one-stage carbonization of vegetable raw materials unauthorized hydrophobization of the sorbent surface is carried out. For fast and efficient collection of oil and oil products, the sorbent must have the maximum sorption rate, which will reduce the absorption time of pollutants. The highest sorption rate is shown by a mixture of pine sawdust carbonate: expanded graphite (50:50) and carbon material based on pine sawdust, which can be explained by the developed porous structure and surface chemistry of the materials.

Abstract
For the rational and sustainable forest use, some representative (reference) areas of ecosystems being high conservation value forests within the leasing estate of Tolshmenskoe, LLC, were selected. After that, the monitoring study for the assessment of the forest breeding, environmental and medium stabilizing functions and the reproduction capacity of the preserved forest ecosystems was carried out. Within the ecosystems, six sample sites were drawn and the survey based on the standard forest ecology methods was performed. The objects of the study (sample sites) were shaped to cover the maximum of all types of forest communities available at the leasing estate. Generally, the monitoring observation showed that the arboreal plants growing in the studied sample sites featured high resistance. The forest formation process is continuous but requires some silvicultural practices, such as appropriate care to stimulate the domination of the economically valuable wood species.

Published: September 2020

AbstractCurrently, the search for alternative renewable fuels for internal combustion engines is becoming strategic. At the same time, it is necessary to work on adapting and improving the design of power transport units, conduct research on optimizing the composition of fuels, their quality and safety, and improve the combustion process of fuels in the cylinder. Vegetable oil-based fuels and alcohol-based fuels are well established and widely distributed. Their valuable property is that when burned, they are less prone to the formation of toxic components and carcinogens. The purpose of this work was to analyze the characteristics of the diesel engine and the combustion process when working on ethanol and rapeseed oil when changing the ratio of cyclic feeds. At the same time, diesel fuel was not used and alcohol fuel was injected into the combustion chamber by a separate injector and ignited with a flame from the rapeseed oil. A 2F10,5/12,0 tractor diesel was upgraded to run on alternative fuels. The article presents the effective characteristics, indicator diagrams, the functions of heat dissipation and the average gas temperature at various portions of the rapeseed oil. The optimal relations portions of the fuels (ethanol and rapeseed oil) is established and justified.

Published: September 2020

AbstractIn recent years, energy indepence from petroleum fuel has been of considerable interest in agriculture. In fact, occasional tightening of standards on toxic emissions combined with rising prices for diesel fuel, force scientists to look for alternative fuels. In this article, such fuels are represented by methyl alcohol, as the main fuel, and rapeseed oil methyl ether, as the fuel that is needed for the ignition of alcohol. The paper shows the characteristics of combusting these fuels in the diesel engine 2F 10.5/12.0 under various loading conditions when using a dual fuel system. The graphs of the indicator pressure and roughness of the combustion process during the operation of a diesel engine at a frequency corresponding to the nominal operation mode and maximum torque are presented. The article presents the analysis of the obtained diagrams and conclusions on the use of the above mentioned fuels in diesel engines.

Published: September 2020

AbstractAt present, the use of renewable alternative fuels of non-petroleum origin has become a challenge. Primarily, this is due to the fact that oil resources are gradually being depleted, and their cost is growing proportionally every year. Switching to renewable fuels will reduce air pollution and ensure independence from crude oil. The article presented describes the results of bench tests of an air-cooled diesel engine 2F 10.5/12.0 running on methyl alcohol and methyl ether of rapeseed oil. Herewith, a dual fuel supply system was used. That allowed ensuring synchronous fuel feeding into the engine cylinder. The article also presents diagrams of indicator pressure, heat release and roughness of the combustion process of a diesel engine running on alternative fuels, depending on the change in the crankshaft speed. Along with this, positive environmental effects were also revealed in terms of the amount of toxic agents in the exhaust gases of a tractor diesel engine. Thus, there is a significant reduction in nitrogen oxides (by 47.4%) as compared to the diesel process, and the soot content in the exhaust gases has decreased by 10.42 times.
