Agriculture is one of the important and complex sectors, it is not only a simple economic sector but also a biological - technical system. Because the basis for agricultural development is the use of bio-energy - plants and animals. Agricultural sector, if understood in a narrow sense, is only the cultivation, husbandry and service sectors. As for agriculture, in broad terms it also includes forestry and fishery. Agriculture provides food and food for social needs, agriculture is the basic material production industry, plays a major role in economic development in most of the country, especially in developing countries. At present, Vietnam’s agriculture has great potential and can be enriched from agriculture. However, wastage and loss in agriculture are still high in the stages of processing, harvesting and preserving. Mechanization is still low, lower than Thailand, so agricultural labor productivity is not high. Over the past years, Vietnam’s Agriculture has achieved important developments, contributing to the development of Vietnam’s economy. However, to achieve higher goals in the next 10 years, Vietnam’s agriculture needs to promote its strengths, such as: Well implementing land policies in agriculture; training high quality human resources; building a credible agriculture, which is clean, safe, quality agriculture and organic agriculture; protect natural environment, such as: land, climate, weather, hydrology, etc. In order to ensure sustainable agricultural development.

Published: June 2020

Cows’ milk productivity determining method of includes: determining the amount of milk during control milking, milk sampling and analyzing its fat and protein content for each milking, they are the same indicators for the day; calculating the conversion coefficients of milk amount and the mass fraction of fat and protein for each milking into daily indicators. Then one control milking is performed per day, and the same indicator is calculated for the same type of feeding, maintenance, and milking based on its indicators multiplied by the Corresponding coefficient. The time intervals between milking being unequal, milk productivity is more accurately determined by a single milk yield after a longer interval between them. For this method, milk cows are taken from the tenth day of lactation and more. The method allows reducing labor costs and working hours of operators and laboratory assistants to daily determine the dairy productivity of cows, as well as to reduce the stress load on animals.

Authors: Obvintseva Olga , Erimbetov Kenes , Mikhailov Vitaly
Published: June 2020

One of the approaches to creating biologically active additives for use in pig breeding can be the use of 20-hydroxyecdysone regulating protein metabolism in piglets. The purpose of the work is to assess the effect of 20-hydroxyecdysone on turnover of protein in piglets. The experiment was carried out on barrows (♂ Danish Yorkshire × ♀ Danish landrace) to achieve a live weight of 53-62 kg. At the age of 60 days, 2 groups of piglets were formed: control and experimental. Piglets of the experimental group were injected with 20-hydroxyecdysone at a dose of 1.6 mg / kg body weight. In piglets of the experimental group, in comparison with the control, a decrease in the excretion of nitrogen in the urine was noted (by 26.8%, P <0.05). Nitrogen deposition was higher in piglets of the experimental group by 19.0% (P <0.001) compared with the control. 20-hydroxyecdysone contributed to increased protein deposition in the body of piglets due to protein synthesizing activity. Thus, the use of 20-hydroxyecdysone in pigs increases the efficiency of using amino acids for the synthesis and deposition of proteins in the body.

Published: June 2020

In the literature there is no complete data on the use of slaked lime as a disinfectant disinfectant. All veterinary publications indicate that a 10 - 20% solution of slaked lime has a disinfecting effect. However, the technology of carrying out, as well as modes of disinfection, are not specifically indicated in any literature. There is no data on which infectious diseases they affect, at what concentration, exposure and consumption of the disinfectant it can be applied, on smooth or rough surfaces, the frequency of whitewashing or wet disinfection, etc. Until now, the issue of the solubility of slaked lime in water and other chemical compounds has not been completely resolved. In addition, the lack of a disinfectant - 10 - 20% slaked lime, is a low disinfection efficiency, high corrosion activity in relation to metal products, a large flow rate of a solution of 1 -1.5 l / m2, which is carried out 2 - 3 times by whitewash.

Authors: Tihonov Еvgenii , Bazykin Valentin , Mukhanov Nikolay
Published: June 2020

In this paper, we consider effective delivery of feed to fish cages. The rotary feeders design analysis is performed. Their disadvantages are analyzed. Possible ways to improve reliability are identified: rotor balancing, elimination of moving parts in design. The design of the feeder without moving parts is proposed, which provides the required parameters of feed distribution in cages and at the same time has high reliability and almost unlimited service life. To justify the design parameters of the feeder, we developed design factors that affect the feed distribution process (height of the pipe cut, height of the cone position, radius of curvature of the generatrix), and an integral criterion for evaluating the quality of feed distribution. The integral criterion includes an assessment of the effective area of feed distribution in the cage and its uniformity. A numerical multifactor study was performed and the optimal values of design factors were determined with the maximum value of the integral criterion that determines the efficiency of the feed distribution process. Based on the results of processing the obtained data, the high quality of feed distribution in cages and the prospects of the proposed design of the feeder as a whole were determined.

Published: June 2020

In order to ensure safe working conditions for drivers, strict requirements are imposed on the smooth running of agricultural vehicles. The purpose of this research was to study the vibration load on the driver’s seat when driving vehicle under agricultural conditions. Studies have revealed that the standard KamAZ-43255 car seat string system effectively damps vibrations with the frequency of more than 16 Hz, and practically does not damp vibrations below 4 Hz. It was determined that: at all speeds, the maximum values of vibration acceleration in the vertical plane are located in the second octave at the frequency of 2.0 Hz; peak values of vibration acceleration of the driver’s seat in the horizontal plane are located in the third octave at frequencies of 3.15 4.1 Hz; maximum mean square accelerations in the vertical plane are 3.76 times higher than the maximum permissible standards; at vehicle speed of V = 20 km/h, the acceleration of the driver’s seat in the vertical plane exceeds the permissible values in 3.9 times, in the horizontal plane it exceeds the permissible values in 2.75 ... 2.79 times. Therefore, on agricultural vehicles, it is necessary to install spring systems that are adaptive to operating conditions.

Authors: Antipov Sergey , Klyuchnikov Andrey , Kazartsev Dmitry
Published: June 2020

At the present time the maim quantity of free-running food products, including grains, are dried in units with convective method of heat input. To intensify convective drying, general attention is paid to improving the method of moving and mixing the product with drying agent, to guarantee fast and quality drying. The use of high and super-high frequency allows can significantly intensify the drying processes, because the phenomenon of super-high frequencies energy into heat conversion throughout the processed material volume contributes to the most uniform heating of the product, compared to other heat input methods. The optimal solution for drying free-running food products is a combination of convective and high-frequency heat input methods. This combination allows controlling gradients of moisture content and temperature, changing its directions, which significantly affects quality of the resulting dry product. In this regard, combined approach to drying process modeling is of practical interest: on the one hand, there are used analytical solutions, based on physical laws application or phenomenological equations, and, on the other hand, experimentally established a relationship between temperature and moisture content of media, which is considered as a heat and mass transfer characteristic for each material.

Authors: Buklagin Dmitry
Published: June 2020

The availability of spare capacities for the production of vegetable oil in Russia and the increased demand in the world’s industrial markets stimulate the development of domestic competitive technologies for growing, storing and processing sunflower, soybean and rapeseed. Reducing the level of dependence of oilseeds on foreign analogues is considered as one of the key tasks. Currently, the share of foreign varieties in Russia occupies about 56 % of the acreage of spring rapeseed, 76% of winter rapeseed, 74% of sunflower and 26% of soy. It is shown that the inclusion of foreign varieties of oilseeds in the State register of varieties approved for use in the Russian Federation is not always justified. It is recommended to include in the state register only those varieties of foreign selection that have a statistically significant difference in the indicators of domestic and foreign varieties obtained as a result of their tests in the regions of Russia.

The study investigates the effect of biochar on nitrous oxide emission in Endoargic Anthrosols in the southern territory of the Russian Far East. Biochar (bio-charcoal) was applied in the amounts of 1 kg/m2 and 3 kg/m2 in combination with organic and mineral fertilizers to drained and drain-free fields during the vegetation season, and the five-gas analyzer G2508 (Picarro) was used. Cumulative flows of N2O were estimated. The analysis revealed that biochar reduces the emissions and the cumulative flow of nitrous oxide. The higher the dose of biochar, the lower the emission and cumulative flows of nitrous oxide, regardless of a drainage system. Biochar (1 kg/m2) reduced the cumulative N2O flow from the soil by 52.2% throughout the experiment conducted, while a dose of 3 kg/m2 allowed for 97.8% reduction. The study found that organic and mineral fertilizers can be effectively used in combination with biochar, as N2O emission from the soil with mineral fertilizers is significantly higher than from the soil with organic fertilizers. Biochar (1 kg/m2) combined with organic fertilizers reduces N2O emission by 53.7%, while a dose of 3 kg/m2 can reduce emissions by 88.9%. Biochar (1 kg/m2) combined with mineral fertilizers reduced the flow of N2O by 17.5%, while a 3 kg/m2 dose of biochar used with mineral fertilizers reduced the emission by 85.3%.

Published: June 2020

Today, the decline in soil fertility progress, therefore, special attention paid to the search for new, including non-traditional sources of raw materials that allow cultivating agricultural crops. It is propose to use expanded obsidian as a soil aerator. Obsidian is a volcanic rock, consisting of volcanic glass in which water content does not exceed 1%. A characteristic feature of this stone is the ability to expand under heat treatment. The expansion of obsidian is possible to implement at temperatures of 1050… 1150 °C. It has been shown that due to obsidian expansion it is possible to obtain a light porous filler with an average density of 200… 350 kg/m3, where the heat treatment of 5… 10 mm grains should be performed under temperatures from 1050 to 1150°C, during 3…5 minutes. The mechanical strength of the expanded obsidian is due to the thickness of the internal partitions of the pores and depends on the total porosity. Increased porosity decreases the strength of the expanded obsidian grains as the internal partitions of the pores become thinner. Relatively high mechanical strength develop grains with less porosity, ie lower coefficient of expansion. At the same time, the nature of the external surface of the grain has a significant influence on the mechanical strength. The melted surface,under other equal conditions provides mechanical strength increase of the expanded obsidian.

Nowadays, in the entire palette of famous types of tourism, accessible ecotourism is one of the most promising ones. This area of tourism plays an important social role in the life of people with physical disabilities. Thanks to accessible ecotourism, the environment for people with disabilities is expanding. The paper analyzes the development of accessible tourism using the example of Krasnodar and the Krasnodar Krai, actualizes the need for the development of this type of tourism and establishes its importance for people with disabilities. It was revealed that it is necessary to carry out the state policy of the field of accessible tourism and plan the development of this sector at the state and regional levels using advanced information technologies. Routes that will be equipped with the necessary equipment for a comfortable moving and stay of people with disabilities are presented. The project approach allowed developing a model of mobile application for the development of accessible ecotourism in the Krasnodar Krai and throughout the whole country with the inclusion of all interested authorities in the solution of the problem, pooling the necessary resources and social survey. The results of the study and the experience of personal participation of the authors are given in this paper.

Authors: Ababkova Marianna , Vasileva Olga
Published: June 2020

The survey is aimed to justify system approach to assess companies’ interaction and environment in tourism clusters. Intangibility of tourism product is determined by the specifics of economic entity and territorial authorities’ interaction, that makes it a prerequisite to use system approach for companies’ interaction within regional tourism cluster. The paper identifies institutional environment of business development in tourism cluster taking into accountthe rapid development of communication and information technologies. To achieve this goal the authors analysed the theoretical frameworks of institutional environment of tourism and the process of its formation and factors. The proposed technique is based on system approach and allows to indicate the deficiency in tourism cluster models, taking such critical issues into account as interconnection between cluster actors, regional competition policy, investment climate, development of standards and systems for the services certification, availability of qualified personnel in the region’s labour market, tourism infrastructure, financial and tax policies in the region, network of competitive local suppliers, public policies on tourism, tourism support programs and communication problems. As a result, the rationale of using system approach to evaluate effectiveness of subjects’ interaction in tourism clusters to determine weaknesses in regional tourism clusters was formed

Studies have been performed to evaluate the dynamic effect of columns of the same type of agricultural tanker truck on the beam-bearing systems of transport structures during movement in braking mode. The design scheme of the general oscillatory system is selected, a mathematical and numerical model of its behavior is developed, an algorithm for joint nonlinear oscillations is constructed. On the basis of the developed expert models, a computer complex was created using the simulation package of dynamic and event-driven systems Simulink MATLAB systems. Using it, a series of computational experiments was carried out to simulate situations of passage of convoys of cars with different parameters and with different driving modes. Various parameters varied: the speed of the column, the distance between the cars, the speed at the time of the start of braking, the place where the first car began to brake, the amount of steady deceleration, the number of tank compartments, and the value of operational underfilling. Based on the analysis of the results of numerical studies, the features of the dynamic effect of vehicles convoys carrying liquid cargo on load-bearing systems from the standpoint of the emergence of excess dynamic pressure on transport facilities and the need for its consideration are shown. Cases of a dangerous combination of parameters and driving modes are highlighted, and the need to distinguish such columns in a special class of moving load is shown. A significant increase in the dynamic coefficients of deflections in comparison with solid loads is shown. The need for full-scale research in this area with the aim of introducing amendments to regulatory documents has been proved.

Published: June 2020

This article discusses klystron bunching with post-acceleration, when bunchers are placed in front of the accelerating tube, and the electronic seals previously formed during the acceleration are ungrouped. The processes of acceleration and bunching of relativistic electron beams can be combined when placing the cavity resonators of the klystron buncher in the gaps between the electrodes of the accelerating tube. In this case, the grouping process occurs in accelerating gaps.

Published: June 2020

The article contains the following technical proposals for the power supply of autonomous agricultural facilities using renewable energy sources: the use of hybrid solar-wind power plants, the use of vortex wind power plants with a vertical axis to use both the energy of horizontal wind flows and the energy of upward air flows. The structure and operation algorithm of an autonomous power supply system based on a hybrid solarwind power plant and a diesel generator for autonomous agricultural facilities of small and medium power in regions where there is no distribution electric network are proposed. This system will allow for insufficient wind load to ensure reliable power supply to an autonomous agricultural facility with minimal use of diesel fuel. The design of a vortex wind power installation has been developed. The fastening on the shaft of the wind power installation of a conical helical blade with a variable radius, decreasing in the direction from the lower to the upper cut of the socket, improves the efficiency of the installation. The proposed installation makes it possible to use small winds and low-potential thermal ascending air currents, reduce low-frequency vibration and noise, and also increase the stability and efficiency of use of wind energy.

Published: June 2020

Conductive asphalt concrete can eliminate snow and icing on road areas, and is a research hot topic for intelligent snow removal. By adding graphite, the electrical resistivity of asphalt concrete can be reduced to achieve the purpose of electrical conductivity. However, the aggregate electrical resistance in asphalt concrete is very large and does not play a conductive role. It is a new technical idea to use steel slag with good electrical conductivity as aggregate to mix graphite powder with good electrical conductivity to prepare steel slag graphite conductive asphalt concrete (SGCAC). In this paper, the effects of steel slag and graphite on the conductive properties of steel slag graphite conductive asphalt concrete are separately explained, and then the conductive mechanism and electrical resistance stability of the conductive slag and graphite are studied.

Published: June 2020

Production premises should be provided with air conditioning in order to ensure and maintain required indoor climate parameters for proper technological process running. The paper presents analytical dependences that allow assessing the amount of heat supplied into a premise of processing meat products. A method of determining air parameters was proposed for implementing central conditioning under a technological process running in a premise. For a warm season, the air handling processes that involve or do not involve after-warming were drawn up using Id-chart depicting the state of humid air; the need for air recirculation was observed. The need for dehumidification of inlet air was defined and recommendations were proposed to be fulfilled. The method for evaluation of recirculation air amount was amended. For a cold season, the air handling processes that involve or do not involve preheating were drawn up using Id-chart depicting the state of humid air; the system of free cooling was proved reasonable to apply.
