Authors: Tepina M S , Gorlenko N V , Murzin M A 
Published: March 2021

Abstract
The aim of this paper was to study the characteristics of porous composite materials based on man-made waste from aluminum and silicon industries. Using chemical and X-ray diffraction methods of analysis, it was found that the dust of silicon production consisted, on average, of 86% silica, and the remaining harmful impurities, due to their low content in the samples, were not recorded by the device, which indicated the potential use of this man-made material as a basis for the development of sorption material. Also, the dust of electrostatic precipitators from aluminum production was used in the samples. Liquid glass was used as a binder for the above-described components. This substance has adhesive properties; in addition, it is known that the interaction of NaOH, which is part of liquid glass, and fine-crystalline silicon is accompanied by active release of hydrogen following an exothermic reaction. Therefore, fine-crystalline silicon was used as a reagent for imparting a porous structure to the sorbent. The increased content of fine man-made waste near metallurgical enterprises proves the need for their use in various industries. Furthermore, studies have shown that the studied industrial materials can be used as raw materials for the production of sorbents.

Abstract
The aim of the work was to study the ecological plasticity of soft spring wheat. To achieve this goal the following tasks were defined: to evaluate varieties of soft spring wheat by yield, elements of environmental plasticity and stability, using the principle of ranking varieties, to evaluate their adaptability to environmental conditions. Varieties of soft spring wheat «Altaiskaya 70», «Kanskaya», «Novosibirskaya 15», «Novosibirskaya 29», «Novosibirskaya 31», «Novosibirskaya 41», «Omskaya 32» and «Vavenkov’s memory» were the objects of research. The parameters of ecological plasticity and stability (bi, σ) were calculated using the method of S. A. Eberhart and W. A. Russell, the homeostatic index (Hom) was calculated using the formula of V. V. Khangildin, and stability parameters of spring wheat were calculated using the method of E. D. Nettevich. The varieties «Kanskaya», «Omskaya 32», «Altaiskaya 70»realized their yield potential in the conditions of the variety testing area to a greater extent. Comparison of different methods for evaluating varieties for stability and plasticity showed that their resolution was not the same. The most complete information is provided by the use of several methods, while it is more convenient to use the principle of ranking varieties by all parameters and to evaluate them by the sum of points. Under contrasting growing onditions, the varieties showed different adaptive properties in terms of yield. It responded to improvements in growing conditions well and reduced yields in adverse conditions to a lesser extent.

On the content of total sulfur in raw coals of various grades
Authors: Koval’ Yu N 
Published: March 2021

Abstract
The environmental safety of using coals and their combustion efficiency depends on the total sulfur content. The author analysed the sulfur content of the coals of the Irsha-Borodinsky, Altai, Irkutsk and Kuznetsk deposits. Gravimetric analysis was used as analytical methods. The results of the study showed that the coals taken from the boiler houses contain from 2.7% to 3.9% of total sulfur and belong to the sulphurous group. These coals are noticeably inferior to the high-quality coals of the world market in terms of their sulfur content. This means that the fuel does not meet the high requirements for environmental friendliness when burning and can harm the ecosystem.

Abstract
The article presents the results of theoretical and experimental studies of new solution of the applied research task that consists in mathematical modelling of the interaction process of concave disk spring shanks and a soil medium, taking into account the random nature of soil response, in the form of a non-linear dynamic movement model. It has allowed for determining the optimal dynamic characteristics and the design parameters of the spring shanks of a disk operating element: rigidity, reduced mass, frequency and amplitude of oscillations. A structural diagram of the interaction process of a concave disk and the soil, where oscillations of an operating element on a spring shank with a certain amplitude and frequency create a feedback in the system “soil – disk – spring shank”, has been suggested. A mathematical model has been developed and a theoretical investigation on the change in the drag forces of a disk operating element on a spring shank has been conducted. The dynamic characteristics of a spring shank in the course of unit operation have been determined within the range of the rigidity variation limits from 20 kN/m to 40 kN/m, the reduced mass limits from 100 N to 300 N, the draft force variation limits from 200 N дo 2000 N.

Published: March 2021

Abstract
For sowing grain crops on stubble, stubble seeders with tine coulters are used, which perform technological operations in one pass. However, they do not meet the requirements of the agricultural machinery to ensure an even distribution of seeds in the sub-spear space. The subsoil no-drill planting creates the most favorable conditions for growth and development of cultivated crops and at the same time, grain crop yields are increased on average by 10…30%. Using no-drill planting, seeders equipped with spear coulters with spreaders for no-drill subsoil seeding provide the best quality and distribute the seeds evenly over the field. The article proposes the original design of the seed drill coulter for no-drill planting, which provides an even seed distribution over the feeding area. As a result of the theoretical researches the optimal parameters of the diffuser for the grain drill coulter are determined and the dependence between the unevenness on the test parameters of the diffuser and the height of the pendulum spreader, the base diameter are obtained. The purpose of this research is to develop the design and rationale of parameters of the grain drill for subsoil no-drill planting, the use of which will reduce the uneven distribution of grain crops seeds or mineral fertilizer granules.

Abstract
Until recently, only the trunk was recognized as valuable in the forestry industry, and everything else, including the crown, was considered waste that cluttered the areas of cutting areas, and was also considered a dangerous raw material in the event of possible fires. Currently, only about 700 thousand tons of wood waste is used, which is no more than 4% of the resulting amount of potential raw materials that could be used at wood processing enterprises. Analysis of the processes of formation and use of felling waste showed that today coniferous greenery has found its application as a raw material for the production of coniferous flour, which is produced directly at the cutting area. After the needles are separated, branches remain in the cutting area that have not found further use. One of the promising areas for the use of logging waste after the separation of needles is the production of wood flour, which has found its wide application in many industries. In the course of research, a design of a mobile device for processing felling residues in a felling area into wood floor was proposed and a laboratory prototype was made. In the course of the analysis of the results of experimental studies, the influence of the design and technological parameters of the device for obtaining wood flour from felling residues on the quality indicators of the finished marketable product was revealed. Statistical and mathematical equations and graphical dependencies have been obtained, which make it possible to predict the qualitative characteristics of wood floor for given design and technological parameters.

Published: March 2021

Abstract
The paper investigated the possibility of using modified woodworking waste to remove heavy oil products from the water surface by sorption. Sawdust of a heart-shaped linden tree (Tília cordáta) was used as sorption materials and used diesel engine oil was used as a sorbate. In order to improve the sorption capacity and increase the sorption capacity of wood waste, they were treated with ultrasound at a frequency of 35000 Hz in an aqueous medium for 4 hours. The physical and mechanical characteristics of modified sawdust have been determined: bulk density, ash content, buoyancy. Experiments on modeling engine oil spills on the water surface have shown that linden sawdust, subjected to ultrasonic action, are effective sorption materials in relation to used diesel engine oil. The degree of water purification under static adsorption conditions reaches 99%.

Published: March 2021

Abstract
This article is dedicated to increasing of removing of nitrogen and phosphorus in DENIFO technology, and the removing of phosphorus by reagents. Removal of nitrogen and phosphorus from municipal wastewater prevents eutrophication of open water, which has become a global problem. A list of conditions that provide maximum efficiency of the processes of wastewater treatment and sludge treatment is completed. Functions of primary settlers, air tanks (based on technology DENIFO), and secondary settlers is reviewed. Pre-denitrification of the returned active sludge with the partial flow of waste water improves anaerobiosis in the anaerobic zone of biological block, and promotes intensive dephosphorization. The work was made under normal conditions of wastewater treatment plant. Unfavorable periods (snowmelt, torrential rains, floods) are not taken into consideration. Mathematical equations are made for the average flow of wastewater during dry weather. Combined dehydratation of the sludge and sediments (the long stay in the tank) leads to rapid displacement phosphorus phosphate to drain water, and a corresponded increase the content of phosphorus in the treated water. Also recommendations for changing the operating mode of the block of sludge treatment given. The important results included in article was taken on the really functioned wastewater treatment plants of Saint Petersburg. This work is aimed at a comprehensive assessment, development and improvement of technology of removing nitrogen and phosphorus from municipal wastewater, including from secondary pollution coming from the return flow from the sludge treatment units.

Abstract
Weather conditions in the risky cotton growing area largely determine readiness of the agricultural background of the cotton field for machine harvesting of cotton. A combined cotton picker with replaceable horizontal spindle and vertical spindle devices was invented. At full (85-90%) opening of cotton bolls, an option of a cotton picker with horizontal spindle is applied, and at incomplete (55-60%) opening – an option with vertical spindle devices is applied. Field trials of a cotton picker with removable devices were carried out. The estimated parameters were completeness of cotton harvest, residue on bushes, losses to the ground, debris and moisture of harvested cotton. Use of a combined cotton picker allows to harvest cotton selectively at full and incomplete opening cotton bolls. Productivity and cotton-picking quality has increased.

Abstract
Due to climate change, all the inhabitants of the Earth are increasingly observing various natural anomalies. The consequences of global warming are particularly noticeable for Russia, where it is about 2.5 times faster than in the rest of the world (the Russian Federation almost does not experience the softening influence of the ocean due to geographical features, so the climate is particularly sensitive). In order to successfully forecast climate change and develop an adequate adaptation program, it is necessary to assess the volume of emissions of the main greenhouse gas CO2 in a timely manner. Since the final carbon footprint of the Russian Federation largely depends on the environmental awareness of the young generation and its contribution to the existing climate change problem, the subject of this article was the average carbon footprint of young people (18-25 years old) in the Russian Federation.

Published: March 2021

Abstract
Perspective type of mechanized parkings is a multi-storey rotary parking system. It is the most efficiency type, but it costs relatively high per unit of parking space. Lower speed of transportation of cars in comparison with other parking types slightly influences on productivity, because an efficiency of work of the device is firstly defined by duration of stages of loading and unloading of cars. The main disadvantage of multi-storey car parks compared to conventional parking lots - is the need for increasing costs for the operation of the lifting device. One of the methods of improving the energy efficiency of lifting and transport machines is the development of structures with energy recuperation. It allows the kinetic energy of the moving parts at the stage of braking to be accumulated in the battery, and to get used for acceleration when performing the next movement. The article describes the mechanism of a rotary-type parking lot with a flywheel energy storage device, and its principle of operation. The characteristics of a flywheel energy accumulator are well suited to the task. In terms of the specific energy reserve per unit of weight, the flywheel battery effectively competes with the electric one, differing from it by a higher working life. Also, its properties do not deteriorate at low operating temperatures. The justification of the choice of the required parameters of the flywheel, the analysis of its shape and the choice of material from which the flywheel can be made.

Abstract
The study by infrared spectroscopy of the structure of liposomes used in veterinary medicine as nanocontainers for the targeted delivery of medicinal substances to the cells of body tissues is a very important area of research. In the process of obtaining liposomes and liposomal preparations, processes of phospholipid modification occur. At present, the method of IR spectroscopy is used to control the deposition of substances on the surface of a liposome in order to study the delivery of drugs, etc. The comparative study of liposomes obtained by different versions of the injection method was first carried out by infrared spectroscopy. According to the results of medium-wave spectroscopy, the peaks of absorption of IR radiation in various wavelength ranges for these liposomes were revealed. This indicates the presence in liposomes of groups of atoms -CH3, -CH2-, primary and secondary alcohols, cis- and trans-isomers HRC = CR´H, groups –OH, groups C=O, solid fatty acids. The results of the study can be used as reference identification IR spectra for the express identification of liposomes obtained by the injection method, and the use of the Fourier IR spectroscopy method for studying the structure of liposomes with encapsulated potassium orotate can be of wide practical importance as a method of express analysis.
