Authors: Nemtsev Anatoly , Voronin Dmitry , Demenok Irina 
Published: December 2019

Abstract
A decrease in the technical potential of the agro-industrial complex of the regions and Russia due to a decrease in the availability of equipment and significant aging is shown, which imposes special requirements for ensuring its performance due to a well-organized technical service. It is possible to maintain high availability of machinery through the regional system for ensuring the operability of agricultural machinery. The aim of the study is to develop a method for ensuring the operability and availability of equipment for its effective use based on the use of service technical clusters. The system for ensuring the operability of agricultural machinery provides various options for servicing consumers from the following levels: economy, district and region. A normative and calculation method is proposed for determining the parameters of the regional system for ensuring the operability of agricultural machinery in order to reduce labor intensity, according to which its parameters are calculated for model technical service clusters: economy and district. The obtained parameters for model levels of the economy and the district are adjusted taking into account the main actual indicators for the zone served by this level of the system. The proposed regulatory calculation method for determining the parameters of the system for ensuring the operability of agricultural machinery was implemented for the Novosibirsk region. Based on a certain laboriousness of the equipment being serviced, a regional model service cluster and a model service cluster of a farm (a farm with average indicators for the region) are substantiated. The conversion factors from model service clusters to actual enterprises at the district and farm levels are given.

Published: December 2019

Abstract
The paper is devoted to studying the motion dynamics of stem and ear, as well as particular wheat grains. The purpose of this consideration is to establish parameters of the effect on the plant as a whole, and in particular on the ear, for the efficient extraction of grains from the ear. For this, a mathematical model of the interaction between the elements of the stem-ear-grain system and the conditions for the separation of grain from the ear is built. In a first approximation, a simple stem model consisting of absolutely rigid bodies interconnected by elastic bonds is taken as such a model. Stems with a given moment of inertia act as such bodies, and spiral springs act as elastic bonds.

Published: December 2019

Abstract
There are many devices for determining the coefficients of external friction, but there are almost no devices for determining the coefficients of internal friction of bulk products. The paper considers the question of physical and mechanical characteristics of bulk materials - the coefficients of external and internal friction. The purpose of this study was to create a device for determining the friction characteristics of bulk materials and its approbation by determining the coefficients of static and dynamic friction of grain materials. The basic parameters of the installation to determine the friction characteristics of bulk materials were defined - static and dynamic, internal and external friction coefficients. The developed installation allows measurements of shear forces inside the bulk material. The relationship between the coefficient of static and dynamic friction in organic and inorganic bulk materials is revealed. Grain crops have a higher value of the dynamic coefficient of friction at a speed up to 0.215 m/s. The difference between the values of static and dynamic friction coefficients was not revealed in the specified speed range of legumes. Dynamics of change in the coefficient of friction for grain crops depending on speed is studied using the example of wheat, and for mineral materials - using the example of table salt. For a speed range of 0-0.215 m/s, the relative change in the coefficient of friction for grain crops has a polynomial regression model, for mineral materials it has a logarithmic.

Published: December 2019

Abstract
The results of studying the intramuscular administration effect of ethyl methylhydroxypyridine succinate are presented in the article, as well as administration of the Flunidzhekt drug and the new Antioxidant anti-inflammatory drug for animals on the course of aseptic inflammation in white laboratory mice. After provoking the inflammation by subcutaneous turpentine oil injection, experimental animals were administered intramuscularly with abovementioned pharmaceutical substances for five days. Abscessing soft tissues of white mice obtained from an inflammatory lesion were subjected to microscopic examination. Microscopy of substances obtained from animals of the control group, in which no therapeutic agents were used, established that the pathological process proceeded against the background of significant leukocyte infiltration of the affected areas. In contrast, development signs of regenerative processes were observed on microsections made from the tissues of mice that were injected with ethylmethylhydroxypyridine succinate. The onset of those signs was predicted by the increase in the proliferation of fibroblasts with a decrease in leukocyte infiltration. After using the “Flunidzhekt” drug, it was noted to be highly effective in suppressing the intensity of the inflammatory process. But it was also noted that the most optimal microscopic picture was observed in pathological tissues obtained from animals that used the Antioxidant anti-inflammatory drug for animals. The use of ethyl methylhydroxypyridine succinate has a positive effect on the course of the inflammatory process, helping to reduce pathological changes in tissues in the outbreak and accelerating the healing process. Moreover, the use of the Antioxidant anti-inflammatory drug for animals helps accelerate the regeneration of the outbreak and reduces the severity of its pathogenetic effects.

Abstract
The present paper considers a hydraulic unit of high-pressure plunger pump that relates to the main types of equipment for oil-and-gas well drilling, completing or repairing. The problem of fatigue breakdowns of hydraulic units of high-pressure plunger pumps is posed in the paper. According to the leading pump manufacturers, the main source of stress concentration in a valve casing of a pump is the edgings of crossing of cylindrical surfaces of seating fits, valves or plunger bores. The value of stresses in the concentrator zone was assessed, and values of safety coefficients of fatigue strength depending on geometric parameters of stress concentrators were compared. To solve the problem set by the leading manufacturers of pumps, the full-scale model of hydraulic unit was elaborated, stress condition and its effect on fatigue parameters of valve casing of hydraulic unit of oilfield high-pressure plunger pump were analyzed. The obtained calculation results quantitatively clarify the pattern of stress distribution in zones of stress concentration in a valve casing of hydraulic unit of a high-pressure plunger pump. Certain conclusions were made on how the parameters under consideration affect the values of fatigue stresses and on priority research directions for the problem under study.

Abstract
The article conducted a study of the working conditions of the combine operator, as a result of which it was revealed that the occupational hazards of an employee are unfavorable microclimate parameters. Based on the analysis of the thermal state of the combine cab during the summer and winter operation, a microclimate normalization system has been proposed, for which the main functional characteristics (cooling and heating capacity) have been determined. According to the results of the calculation, the relationship between these characteristics and the working speed of the combine is established. So, with the increase in the speed of the combine up to 20 km/h, the cooling capacity of the climate system increases by 36%, and the heat output – by 22%. The surface areas of the main elements of the microclimate normalization system (condenser and evaporator), providing the necessary performance, are also determined.

Authors: Byshov Nikolay , Makarov Valentin , Makarova Olga , Gasparyan Svetlana , Novozhilova Zhanna 
Published: December 2019

Abstract
The article uses a systematic approach when considering the implementation of field work by planting and harvesting complexes. It was established that for the full use of the capabilities of these complexes at minimal cost, mechanized work must be carried out at the maximum values of the shift time utilization factors. The tabular form shows the values of the shift time utilization factors for the conditions of the Non-Chernozem Zone of Russia. The choice of work strategy determines the maturation rate, weather conditions, and the availability of technical equipment. Numerical compositions of planting and harvesting complexes per 1 ha are proposed, which are presented in tabular form when aggregated with tractors of class 1.4; 2; 3. Effectiveness evaluation of the complex functioning should be based on the activities of all subsystems to implement the work plan. Such an evaluation of the daily work of the complex can serve as a coefficient of work intensity equal to the ratio of the amounts of actually completed work to the planned ones. The conclusions establish ways to improve mechanized processes for planting and harvesting grain crops, and as an optimal option, the option of maximizing the use of shift time due to the introduction of new organizational and technical forms was chosen. As a result, a mathematical model for the functioning of planting and harvesting complexes in the production of grain crops for the Non-Chernozem Zone of Russia, which can also be used for other regions, was developed.

Published: December 2019

Abstract
Reliable operation of a diesel engine largely depends on wearing degree of joints and assemblies of fuel injection equipment. The precision components of the high-pressure fuel pump and nozzles are most susceptible to wear. The following methods are used to reduce the wear of precision pairs of a high-pressure fuel pump: increasing the hardness of the mating parts, improving the filtering quality of the fuel and increasing the fuel lubricity. From the point of implementing easiness and obtaining the greatest effect, the most promising is improving the lubricity of motor fuel. It is possible to increase the lubricity of motor fuels by using liquid fuels of biological origin or by introducing vegetable-based fluid into commercial mineral diesel fuel, for example, cameline oil. The fuel kinematic viscosity effect on the wear of the precision pairs of the fuel injection equipment in diesel engines is theoretically substantiated. The results of bench tests of a high-pressure fuel pump for wear of plunger pairs (inner cylinder - bush bearing) during operation with mixed cameline-mineral fuel are presented.

Published: December 2019

Abstract
There is a growing interest in African Clary catfish as a perspective object of industrial fishery in the Russian aquaculture in the last decade. This interest is due to the high growth rate of Clary catfish, its delicious meat and valuable caviar. This species has multiport spawning, so it is possible to get caviar from catfish several times a year. However, in high-tech industrial system of fish breeding, biology of fishes is modified, so that the African Clary catfish loses the ability to reproduce and produce full roe. For reproduction and production of full roe in industrial aquaculture, artificial spawning technologies are used with the use of hormonal drugs that induce the maturation of reproductive cells. The study is devoted to the dynamics of puberty in female African Clary catfish to identify the starting age of its possible use in the reproductive process and in the production of caviar. The results showed that at the age of 8 months, the reproductive system of females reached maturity, females were able to reproduce posterity. However, its reproductive performance in this period, in particular caviar productivity, was very low. The age of 12 months can be considered the starting age for caviar production. Caviar productivity continued to grow, reaching a maximum at the age of 18-24 months, and depended on the weight of females. Working fertility of females and gonadosomatic index at the age of 12-24 months were characterized by increasing dynamics. The size and weight of oocytes during this period reached definitive sizes.

AbstractThe morphology and topography of atypical lymph nodes of Korean water deer (Hydropotes inermis argyropus) is described for the first time. The aim of this work was to study the structural organization of atypical lymph nodes in water deer. Fresh organ samples were taken from 5 adult water deer. Samples are fixed in formalin and embedded in paraffin wax (Hystomix). Stain serial sections, 4-5 μm thick, are stained with hematoxylin-eosin, Masson’s trichrome stain, Gomori’s silver impregnation stain. Atypical lymph nodes in Korean water deer are located on the trachea along the jugular vein and under the trachea on the internal carotid artery and internal jugular vein. The nodes are localized on the adipose tissue of the pericardium in the thoracic cavity, as well as directly on the aortic arch. In the abdominal cavity, nodes are located along the caudal cava and abdominal aorta, as well as in the connective tissue layers of the pancreas. Organs have a dark red color, oval or round shape, its size - from millet grain to peas. Atypical lymph nodes are heterogeneous organs that differ not only from the usual lymph nodes, but also from each other, both in the type of bringing vessels and some features of the structure. Based on a detailed morphological study, atypical lymph nodes in the abdominal cavity were subdivided into 3 types: 1) hemolymphatic nodes; 2) venous hemal nodes and 3) arterial hemal nodes.
