Published: December 2019

Abstract
A description is given of a vertical paddle mixer with a batch action of bulk materials. Based on the obtained experimental data, part of the previously published and newly identified equations of regression of mixing unevenness, the functions of the factors of the empirical mixing intensity coefficient are obtained. They take into account the influence of technological (proportion of the control component, volume of a mixing tank and its degree of filling), operating (mixer angle of the blades) and design(number of blades, blade length) mixer parameters. Based on the interconnection of the functions describing the power consumption, the required duration of mixing and the mass of the prepared mixture, a mathematical model of specific energy costs is obtained. Graphic materials are presented that make it possible to evaluate the combined effect of the mixer parameters on the mass of the prepared mixture, the duration of mixing, power consumption, and specific energy consumption. The rational use of the mixer with a share of the control component of at least 10%. With an increase in the stirrer rotation frequency of more than 350min-1, the intensity of the reduction in mixing time slows down. Reducing a portion of the mixture reduces energy costs. In terms of energy consumption, small mixers are more efficient, but they have low productivity.
Improving the design of actuator rod cultivator
Authors: Saleyev Farid , Yakovlev Vasiliy 
Published: December 2019

Abstract
Classification of continuous tillage cultivator rod drives is given. It is shown that to effectively kill the weeds with a rod cultivator, the rod must be buried in the soil and rotate in the opposite direction of rotation of the cultivator support wheels. It is shown that the existing designs implementing this requirement are rather complex. A simplified design of the extension without mechanical rod drive from the cultivator drive wheels, which provides the required direction of rotation of this working tool, is proposed and analyzed.

Abstract
In modern conditions of economic development, agricultural organizations are faced with the need to manage their property and obligations in situations of risk and uncertainty. Accounting and analytical support is becoming an important source of information for making effective management decisions. An important stage of management at all levels is control. Effective control is not possible without consideration and analysis, which causes certain difficulties. The risk management system works with all identified risks of the organization. The accounting system covers a limited number of risks with the necessary parameters for their registration and acceptance for accounting. When registering risk, each type of accounting (financial, management, tax, statistical) is determined by its goals, uses different methods of assessment, etc. The reporting in each case meets specific criteria. Differences in the principles of accounting and assessment of one risk in several accounting systems cause difficulties in the practice of risk management. The risk management process has its own procedure regulated by international and national standards for risk management, which do not contain unified actions regarding further accounting measures for identified risks. This leads to a decrease in the quality of information regarding risks to ensure control and management procedures. At the same time, accounting standards do not provide for management actions for risks accepted for accounting. This paper is devoted to the study of the role of accounting and analytical aspects in the risk management of agricultural organizations from the position of coordination of control actions of risk management and accounting procedures. General scientific methods were used in the study: a systematic approach, comparative analysis, logical generalization, modeling, etc.

Published: December 2019

Abstract
Natural mineral glauconite, which is extracted in the Bondarsky district in the Tambov region, has a high adsorption capacity. The study of its properties as an enterosorbent in the conditions of passage through the gastrointestinal tract of calves was executed. Chemical modification of the mineral was carried out by converting to Na-form. As a result of treatment, the number of bacteria in it decreased 10 times, and the number of molds decreased 3 times. The prepared enterosorbent was fed to 2 and 6-month-old calves once and for 6 and 9 days daily in the amount of 0.2 g/kg of live weight. The content of metals in the mineral, feed and excrement was determined by x-ray fluorescence analysis. According to the results of one-time feeding of enterosorbent to the calf during the milk growing period, a significant sorption effect was observed with respect to copper (13.6%), nickel (52.7%) and lead (93.8%). The use of enterosorbent in the diets of 6-month-old calves contributed to an increase in the excretion of lead from the body of animals up to 36% of the total amount, which on average is excreted with feces.

Authors: Stepina Irina 
Published: December 2019

Abstract
The study of the composition and structure of the reaction products formed in the systems: boric acid – monoethanolamine – water and boric acid – diethanolamine – water at an equimolar ratio of acid and alcohol in an alkaline environment. Using IR-spectroscopy,1H and11B NMR-spectroscopy revealed the formation of monoethanolamine(N→B)-threehydroxyborate and diethanolamine(N→B)-threehydroxyborate, in which the nitrogen and boron atoms are coordinated. In the process of drying the resulting product due to intramolecular condensation, a cyclic structure is formed. In the composition of the boron-nitrogen compounds obtained, the boron atom has a coordination number of four. The resulting boron-nitrogen compounds are effective antiseptics of wood building structures, and also exhibit flame retardant properties. There is boron-nitrogen coordination in the composition of the modifier molecule, due to which nucleophilic attack by water molecules is excluded. Therefore, the modifier is firmly fixed in the composition of the wood and provides durable protection against bio-corrosion and fire.

Abstract
This article deals with the hydraulic transport of river sediments in a cylindrical pipeline. To describe the nature of hydraulic phenomena, experiments were provided for single-phase and two-phase flows in field and laboratory condition. According to the results of the experiments, the main hydraulic parameters of the proposed jet device for hydro transportation of river sediments were determined. Based on the processing of the available data, as well as the data of specially commissioned experiments, the dependencies of flow rates, speed, jet constraining and resistance when the pulp flow from the jet apparatus has expired on the Reynolds number, are valid for certain limits of Reynolds number change. As a result of special experiments, the dependences of local resistance coefficients on the Reynolds number for some practically important cases (when the net flow and pulp from the jet apparatus pipeline have elapsed), valid within certain limits of change of Reynolds numbers, are established. The design parameters of the jet apparatus for the purification of water bodies from river sediments are substantiated, the design formulas for determining the hydraulic parameters of the proposed jet apparatus are proposed. A calculation formula for determining the flow rate of the slurry jet apparatus is proposed. As a result of special experiments, the dependences of the coefficient of hydraulic friction on the Reynolds number for various saturations of flow with a suspension are established. The article offers a new method for determination critical velocity two-phase current, and proposed method is valued with given laboratory condition.
Water filter with central perforated pipe for livestock complexes
Authors: Saitov Viktor , Kotyukov Anatoly 
Published: December 2019

Abstract
Improving the livestock sector is a priority for the development of agricultural production in the Russian Federation. The development of animal husbandry to a certain extent depends on the use of clean drinking water. The use of contaminated drinking water for animals and birds leads to the accumulation of harmful and toxic substances in meat, milk and eggs. The use of such products by people significantly affects their health, leads to various diseases and shortens life expectancy. To filter water from various impurities, slotted filters are used in livestock complexes that do not provide high-quality water purification. A prototype of a filter for water purification with a central perforated pipe with a productivity of 5 m3/h with an increased service life of the filter bag has been developed. The developed filter provides water purification from high concentration of salts of iron, manganese, chlorine, hardness salts, hydrogen sulfide, pesticides, and also various organic compounds. The purified water is clean and transparent, has a pleasant taste, contains the optimal chemical composition of various impurities, does not contain pathogens and helminth eggs, and therefore meets the high sanitary and hygienic requirements for the safe drinking water for farm animals in the water treatment line of the livestock complex. It can also be used in chemical water treatment units of thermal power plants and other organizations.

Abstract
Composite materials were made by integration of two or more substances, one of them is a supported material like fabric, the other is a matrix material like resin. The outcome of the integration of the two substances produce new material has the attributes differ from the specifications of its constituent materials. This paper presents a comparative study of buckling resistance for cylinders made of a composite material once using a woven cloth as supporting material and the other using knitted cloth. Cylinders have been manufactured, one by woven fabric as supporting material and other by knitting fabric as supporting material, by test the cylinders under the buckling test, we found that the buckle for cylinder producing by knitting fabric is 20% higher than that produced of woven fabric. Comparing the scheme (force-displacement) of the test of two cylinder, it was found that the cylinder producing by knitting fabric has a rapid failure, while the other one has a more displacement.
Influence of long-term plowing on water permeability of light-gray forest soils of taiga-forest zone of Western Siberia
Authors: Gruzdeva Natalya , Eremin Dmitry 
Published: December 2019

Abstract
Light-gray forest soils are of particular value to agricultural enterprises in Western Siberia. These soils have a number of advantages relative to semi-hydromorphic soils, which have high potential fertility, but unfavorable water-physical properties. The involvement of light-gray forest soils in agriculture leads to a change in the balance of organic matter and moisture regime. This affects water permeability, which characterizes the main indicators of water-physical properties. The deterioration of the conditions for the movement of water deeper into the soil leads to surface water saturation and the manifestation of water erosion. The purpose of scientific research was to study the influence of long-term plowing on water permeability of light-gray forest soils. It is established that in the virgin state, light-gray forest soils are characterized by the best water permeability. The illuvial horizon has a minimum infiltration and filtration rates, which reach 3.1 and 1.8 mm/min, respectively. Plowing and prolonged use of light-gray forest soils in arable land leads to a deterioration in the speed of movement of water in the arable horizon. The infiltration and filtration coefficients reach 2.8 and 1.1 mm/min, which is almost three times less than the values of virgin soil. Under the influence of an anthropogenic factor, a layer is formed in the upper part of the illuvial horizon with a minimum filtration rate (1.0 mm/min). The ratio of the water speed between the initial and final measurement points indicates the presence of a non-water-stable structure in the humus-eluvial and arable horizons. Therefore, to prevent deterioration in arable land, it is necessary to create all conditions for the formation of a water-stable structure by applying organic fertilizers and lime.

Published: December 2019

Abstract
In the process of designing tillage and other agricultural machines, the main problem is to ensure the quality and optimal energy consumption of technological operations. For existing rotary and milling tillage machines, the main indicators of the quality of work and the energy intensity of the process depend on the kinematic, structural and technological parameters, the ratio of the angular rotational speeds of the disks, translational speed, diameter of the working body, number of cutting elements, depth of cut, ridge height, etc. The ridging of the bottom of the furrow is one of the important agrotechnical indicators of the operation of rotary tillage machines. The height of the ridges should be no more than 20% of the tillage depth. This requirement imposes certain restrictions on the choice of parameters and operating modes of rotary tillage machines. The purpose of the study is to establish the laws of the influence of kinematic and structural parameters of a double-disc rotary working body on the quality and energy intensity of soil cultivation. The object of the study is the process of cutting soil by an active-passive rotary working body. The influence of setting and design parameters on the energy intensity of the working process of a double-disc rotary working body is determined. Power characteristics of the working body, leading to the destruction of the ridge of the bottom of the furrow are defined. Range of adaptive high-speed regulation of the working process of a double-disk rotary working body is established. The energy parameters of the working process of the combined double-disc working body are assessed. It was found that the specific energy consumption of rotary tillage by a double-disc working body is reduced to 20-30% compared to milling. Evenness of the furrow bottom up to 80% is ensured.

Abstract
The paper is devoted to topical issues of monitoring infrastructure facilities. The aim of the study is to compare the already established traditional method of ground-based laser scanning and its aerial analogue based on the use of compact drones in collecting data on road structures. The question was raised about the possible ways to modernize the existing monitoring procedure for the timely detection and prevention of dangerous emergencies at engineering structures. The most effective technologies for obtaining comprehensive information on the technical condition of such structures are analyzed. It was determined that the most rational method from the point of view of information content, mobility and examination time is the method of using airborne laser scanners in conjunction with unmanned small-sized aircraft. The procedure of the entire cycle of obtaining information, including its subsequent processing, is described. The analysis of stationary and other applied methods of monitoring infrastructure facilities is made, their advantages and disadvantages are described. A question was raised about the prospect of creating software that uses artificial neural networks as a means of automating the processes of subsequent processing of primary scan data and analysis of the obtained object model. Conclusions are made about the appropriateness and prospects of using similar tools and methods for the needs of monitoring engineering infrastructure facilities, as well as the need for further development of software that will automatically analyze the accumulated data on the same infrastructure object.
