The central problem of the use of LEDs in greenhouse production is the establishment of a causal relationship between the environment in a parametric microclimate and the manifested properties of a biological object (phenological, biological, spectral sensitivity). Information management systems with biofeedback relate to biotechnical systems in which a biological object directly participates in the formation of control decisions in real time. At the same time, the plant as a biological object detects a feedback channel from the source, which indicates the external plant characteristics (phenomenological and spectral characteristics, intensity of such processes as photosynthesis, respiration, transpiration, etc.).

Authors: Zhichkin Kirill , Nosov Vladimir , Zhichkina Ljudmila
Published: December 2019

The article discusses the situation with the restoration of the machine and tractor fleet of agricultural enterprises in the Samara region and determines the role of individual elements of the economic mechanism. In modern conditions, the main guarantee of the success of agricultural production is the maximum mechanization of production processes. Replacement of manual labor by machine allows reducing the cost of production, increasing its output, implementing modern industrial technologies, reducing the dependence of the result on the human factor. The purpose of this study is to determine the capabilities of agricultural enterprises in the Samara region to modernize the composition of the equipment used. The number of almost all types of energy and agricultural machinery compared with the 1995 level has decreased significantly. At the same time, energy supply per 100 hectares of arable land has stabilized, which is explained by the choice of powerful, productive equipment. The situation can be corrected by increasing the profitability of crop production and correcting the situation with price disparity. Direct government funding for acquisitions has declined. Among the instruments of state support, along with interest rate subsidies, subsidization of expenses for the purchase of cars has been widely used. The amount of subsidies reaches 492.2 million rubles (2013). The applied measures of state support in the conditions of the Samara region are complex and, with prolonged use, can solve the problem of updating equipment.

Published: December 2019

The paper is devoted to summarizing the experience of forming sources of funding in emerging markets and analyzing the efficiency of capital use using the example of agricultural enterprises in the South of Russia. The literature review covers studies revealing the determinants of the formation of sources of capital funding in both developed and emerging markets. It is noted that the features of the establishment of business structures and the country’s financial system are factors in the choice of hierarchy theory by the management of companies in the formation of capital structure. A study of the impact of the weighted average cost of capital on return on assets was carried out using the example of agricultural enterprises in the South of Russia. The obtained results confirm the developed hypotheses about the negative impact of an increase in the volume of debt financing of agribusiness organizations on the return on assets, as well as about the choice of a conservative agricultural policy by agricultural organizations in forming funding sources. These results are close to the results of applied research on the formation of capital structure in other sectors of the Russian economy.

Published: December 2019

The object of the research of the presented article is the internal axisymmetric cylindrical flanging. This work is intended to improve the quality and accelerate the development of technology for flanging round holes from sheet blanks and designing tooling by improving the accuracy of calculating the diameter of the flanging holes in the automated mode for constructing three-dimensional models of a blank and a flanged product. Formulas are proposed that increase the accuracy of calculating the diameter of the hole for flanging. The accuracy of calculating the diameter of the flange hole according to the proposed formulas is determined by comparing the mass of the workpiece with the mass of the flanged part. The algorithm for the automated construction of a sketch of a flanged part and the determination of technological parameters is implemented in KOMPAS-3D. The constructed models allow making changes to their parameters and to provide automatic presentation of the calculation results, as well as their correct graphical interpretation. A discussion of the results of the work allows drawing conclusions about the correctness of the proposed mathematical model and its applicability to the automated construction of three-dimensional models of flanged parts, which will simplify the development of technological and design documentation with a simultaneous increase in their accuracy and reduce the cost of preparing the production.

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.

Published: December 2019

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

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

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.

Published: December 2019

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

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.

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

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.
Rotary working body of the tillage machine
Authors: Ivanov Andrey , Puzyrev Maxim
Published: December 2019

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.

Published: December 2019

In different periods of the life cycle, the chemical composition of fish muscle tissue is subject to significant fluctuations. These changes are most pronounced during the spawning period, when there is a switch to generative exchange. The studies of the nutritional value of the meat of African catfish (Clarias gariepinus) in the spawning period showed that the protein content of this species of fish falls into the category of protein products containing a full range of essential amino acids; by the fat content in muscle tissue, it can be attributed to the varieties of fatty fish. According to the research, the muscle mass of this fish species contains high levels of mono - and polyunsaturated fatty acids and is characterized by high levels of linoleic acid, which is an essential fatty acid. The content of linoleic acid in the muscles of African catfish is much higher than in the muscles of pink salmon. The content of linoleic acid in the caviar of African catfish is seven times higher than in the caviar of pink salmon. African catfish caviar also contains a large amount of oleic acid, which plays an important role in the prevention of cardiovascular diseases. The results showed that during the spawning period, the nutritional value of the muscle tissue of the African catfish remains high. The results of the study are important for the development of African catfish caviar production and give a positive answer to the question whether it is possible to obtain edible caviar from catfish without compromising the production of commercial fish of high nutritional value.

In a tough competitive environment, you can survive and develop only by orienting your business activities to a logistic approach. The gold mining industry plays a key role in the global economy. This industry has a high asset value, large-scale production lines and large infrastructure. One of the main tasks of strategic planning of gold mining enterprises is the choice of a rational marketing system. Planning and selection of schemes for the supply of precious metals is an important condition for the effective functioning of the marketing activities of gold mining enterprises. For these purposes, the need for improving logistics flows and creating an information system for sales planning is growing. The article explores the planning and selection of precious metals supply schemes using the example of PJSC “Vysochaishy”. Much attention paid to the construction of the company’s logistics flows. The main problems in the supply chain of PJSC “Vysochaishy” are identify. The algorithm of the process of introducing a new supply chain planning system for Vysochaishy PJSC is considered, and an improved strategic planning process for PJSC “Vysochaishy” is present. A new scheme of operation of the transport and logistics system for the direction of logistics flows of PJSC “Vysochaishy” proposed.

The methodology developed by the authors for designing a stage-by-stage change the shape and capacity of a multimodal transportation network allows, on the basis of the initial set of strategies, forming the area of effective strategies. This area is used to make an optimal design decision. The article discusses the efficiency of the strategy that stage-by-stage changes shape and capacity of the multimodal transportation network. In this study the strategy efficiency is the strategy compliance with the set goals and interests of potential participants of the investment project for its implementation. At the same time, the use of only economic indicators does not always determine the optimal strategy. For this purpose, in the multimodal transportation network designing methodology a set of interrelated balanced indicators is applied: economic, social, technical, operational, environmental, etc. The article provides recommendations for determining the indicators of economic efficiency: social, national (federal), regional and industry efficiencies included in the Balanced scorecard. These indicators allow estimating possible outcomes of strategies implementation of multimodal transport network development in economic and social spheres for society as a whole, economy of the country, transport industry, and also investment appeal of strategy for potential participants of the project on its realization.

This research was aimed to identify substrates type in the east part of the Banyuasin coastal waters using quantitative backscatter data from single-beam echo-sounding. The SIMRAD EK-15 was used to classify the seafloor substrate types. The ground truth was required for calibrating the acoustic result. Wet sieving methods and Shepard’s triangular diagram were used to analyze the ground truth samples. The acoustic data were filtered to extract the volume backscattering strength of bottom surface (SV) using Echoview 4.0. The data of bottom surface backscattering strength (SS) and SV were classified by using Hierarchical Cluster Method. Data of substrate type from the ground truth will be used as a guideline to classify the SS data to identify the substrate type based on the SS characteristic which associated with various types of the bottom substrate. The results showed the single beam capability in distinguishing the types of bottom substrate, namely clayed sand with the SS value ranges from -47.29 to -46.32 dB), silt + sand + clay with the SS value ranges from -51.00 to -48.54 dB), clayed silt with the SS value ranges from -53.47 to -52.24 dB), and silty clay with the SS value ranges from -56.89 to -55.94 dB.

Published: December 2019

Longterm fluctuation content of heavy metal concentrations (Sr, Cr, Fe, Zn, and Pb) was traced through the analysis of coral skeletal growth bands of massive coral core Porites lutea. Annual growth band was examined using X radiography. Heavy metal samples were extracted from each yearly layer of the core section. Seven samples of the coral skeleton were analyzed using neutron activation analysis and atomic absorption spectrometry to detect metal concentrations. The oldest layer of coring corals obtained from the windward side started from 1940, while in leeward of the island starting from 1969. All five metals from both sides were still detected until 2014. There was significant increase over time of the four metals (Cr, Fe, Zn. and Pb), while the concentrations of strontium remained relatively stable.

Published: December 2019

Salmonella is pathogenic bacteria causing intestinal diseases or thypoid fever. Contamination of fisheries products by these bacteria could lead to a customer dissatisfaction and product recall. In this study, Salmonella contamination in 25 seafood and seafood products obtained from traditional and modern retailers were evaluated using real time PCR. Two primers were designed to amplify a 204 bp target gene specific to Salmonella. These primers were successfully amplified the target gene of Salmonella typhimurium (ATCC 25241). However, the melting curves of the product samples were found below the threshold Cycle (Ct) value, indicating that Salmonella bacteria contaminated none of the fish and fisheries products.
