Abstract
The need to transfer agricultural production to the digital economy is obvious. One of the main factors constraining the mechanisms for introducing digital technologies into agricultural production is the insufficient availability of specialists with the necessary qualifications in the IT sphere in the area of processes and production. The main, in our opinion, criteria that allow us to predict the demand for labour resources with the necessary qualifications have been considered; typical problems of training in the framework of the current education system, associated with insufficient from the point of view of the digital economy, elaboration and specification of Educational Standards and qualification requirements for graduates who were educated by the time of transition to digital production mechanisms have been identified. The possible difficulties of the state of the labour market associated with the reduction of jobs as a result of the intensification and automation of a number of industries using the digital economy and buffer measures of pension legislation have been noted. Options for mitigating the effects of the problems presented by creating a specialized educational structure based on short-term, highly specialized courses, allowing in a short time, depending on the existing skill level of the worker, to bring his knowledge, skills, abilities and competencies in line with the level required for successful work in the framework of digital economy mechanisms have been offered.

Authors: Yu Prudnikov A , Bonnet V V , Yu Loginov A 
Published: August 2019

Abstract
The most common electric motor to drive working machines is an asynchronous one with a short-circuited rotor. It has a fairly large resource, provided proper operation. When analysing faults, it was found that the most common cause of failure is increased wear of bearings. The diagnostic parameter of this fault is an increase in the eccentricity of the rotor, to identify which we have developed a diagnostic method that allows us to evaluate the technical condition of the engine using an indirect indicator, the rotor speed. To make a diagnosis, it is necessary to process the data on the dynamics of change in the rotor speed of the engine and predict its operation for the forthcoming period. To simplify data processing, a program has been developed that is an automated system for analysing diagnostic parameters and can significantly reduce the laboriousness and time of diagnosis, eliminating the influence of the human factor. The developed programme was used to analyse the operation of asynchronous engines in poultry house ventilation systems, to predict their failure, as well as to plan maintenance and repair.

Abstract
The article presents a method for estimating the spatial distribution of spring barley yield, based on the use of optical ground and satellite spectral data (PlanetScope data with a spatial resolution of 3 meters). This approach is highly relevant for the development of precision agriculture technologies. Yield mapping is carried out on the basis of data on the spatial distribution of the actual yield and the spatial distribution of the spectral optical characteristics. The method’s characteristic feature is the use of the integral values of vegetation indices (NDVI, MSAVI2, ClGreen) at various stages of crop development. The method was tested on the basis of stationary field experience, where traditional agriculture (deep plowing) is compared with resource-saving technologies (subsurface and surface plowing, and direct seeding with zero tillage).

Authors: Gryzlov A A , Bukhanov S S , Grigorev M A 
Published: August 2019

Abstract
The article systematizes information on the structure of regulation of non-contact agricultural electric drives with improved mass-size parameters. Regulatory structures with independent control two-zone speed control and sequential excitation are proposed. It is shown that the best indicators are achieved in the scheme of sequential excitation and they reach values of 20-25%. Attention is drawn to the fact that structures with independent excitation are most relevant for dynamic mechanisms that realize the trajectory of motion with the maximum speed. Schemes of sequential excitation are most relevant for mechanisms with a large range of load variations on the motor shaft, for example, agricultural facilities. Schemes with two-zone speed control are most relevant for mechanisms that, with a large increase in speed, significantly reduce the load on the motor shaft.
Analysis of operating modes of electric drives in agriculture
Authors: Tsirkunenko A T , Zagoskin Y S 
Published: August 2019

Abstract
An algorithm for analyzing the operating modes of an agriculture electric machine as a control object based on its generalized mathematical model using the Fourier transform of non-sinusoidal signals of phase currents and conductance along the air gap of an electric machine is proposed, which is applicable to any electric machine with magnetic non-symmetry of rotor and which allows to obtain and investigate the spectral composition of such electric drive’s coordinates as induction and electromagnetic torque. According to such an algorithm, it is recommended to perform the calculation under the following assumptions: the machine is not saturated, the magnetic conductivity of steel is equal to infinity, there are no scattering fluxes. When going beyond these limitations, the calculation must be refined by a numerical finite element method using Maxwell’s equations. An example of an agriculture electric drive with a synchronous reluctance machine of independent excitation coordinates calculations is given according to the proposed algorithm in comparison with a numerical calculation by the finite element method.

Published: August 2019

Abstract
Yaks are unpretentious and extremely hardy. They have a well-developed sense of smell, thick hair which helps them endure harsh climatic conditions. They can live in high mountains and hilly steppes. The aim of the article is to assess adaptive properties of yaks based on morphological and biochemical studies of blood samples and immunogenetic certification by blood groups. Cattle breeding is successfully developing in the Transbaikal Krai. However, yak breeding is a new activity. In 2015, 53 breeding yaks were purchased in the Oka district of the Republic of Buryatia and exported to the Transbaikal Krai. The experimental studies on blood of transported animals identified the high content of leukocytes and the high level of hemoglobin. The lymphocyte, monocyte and red blood cell indicators were within the norm. The calcium content decreased by 0.17 mmol/l. The ratio of calcium to phosphorus was 1: 1.8. The protein content was 72.35 g/l, alkaline reserve – 51.8 v%. The indicators were within the norm. While determining the frequency of individual blood antigens, it was found that the most frequent groups were as follows: J’-52%, X2 - 50%, Z - 49%, D’- 48%, A2 - 47%, V - 32%, G2 - 28%, F - 26%, E - 23%, O2 - 22%, P - 20%. In new conditions, the Oka yaks have high adaptive properties and productive qualities.

Authors: Leontiev D F 
Published: August 2019

Abstract
The importance of hunting design for the rational use of hunting resources is highlighted. As part of hunting, the role of hunting taxation is defined. Using the example of an exceptionally economically important commercial species, the possibilities of a landscape-interpretation approach for mapping the habitats of game animals are shown. The work makes their inventory on the basis of the landscape-species concept of hunting taxation. According to the habitat conditions, optimal and suboptimal habitats are identified, as well as lands unusual for sable. Criteria for the selection of optimal conditions served as the possibility of providing natural complexes of year-round habitat of sable. The interpretation criteria as suboptimal are the worst habitat conditions of the sable and their use is mainly seasonal. Unusual lands are the areas where the species does not inhabit. In general, the work performed shows the use of ecology (biogeocenology) and modern landscape science in hunting management, including for identifying and displaying natural complexes that are extremely important for homeostasis of the sable population. The region has been identified for the special importance of indigenous Siberian pine (Pinus sibirica du Tour) and the importance of this species for sable is shown. Optimal habitats are characterized by sable population density. The current state of the sable population, taking into account the current commercial use, can be characterized by its homeostasis.

Published: August 2019

Abstract
Plants are structural and biochemical systems in which at each moment of ontogenesis are established inherent only to this plant, the ratio of growth, biorhythmic and morphogenetic processes. The conjugacy of circadian rhythm and the activity of chromatin-modifying enzymes is becoming increasingly important. In this aspect, histones play an important role, since they are able to fine-tune transcriptional programs through a series of accurately organized post-translational modifications that combinatorially regulate chromatin function. It is proved that almost all histones are proteolytically modified. It was shown that differences in the exhibition of activity Arg-X proteolysis between spring and winter seedlings are observed mainly in the fractions of core histones at the level of chromatin tightly bound. The preferential localization of Arg-X protease activity was found in the histone (H3 + H4) block as spring and winter varieties. In addition, activity Arg-X proteolysis at the level of nuclear matrix correlated with the growth characteristics of spring and winter seedlings in coleoptiles and roots growing by cell stretching. Results can be viewed as an illustration of a multi-layered regulatory proteinase network involved in proteolytic processing of nuclear proteins, taking part in circadian spatial and temporal structural changes of chromatin states.

Abstract
The article contains the results of hematological, immunological and chemiluminescent analysis of the functional activity of peripheral blood cells of five-year-old lactating cows from the central regions of the Krasnoyarsk Territory (Siberia, Russia) with different radiation status, at which the radiation doses of animals were 0.02, 0.17 and 0.21 mSv per year. It was established that small doses of radiation at 0.17 mSv per year and 0.21 mSv per year affect hematological parameters, increase the phagocytic activity of blood leukocytes and change the kinetics of the formation of active oxygen forms by blood cells, which is manifested as an increase in the time of formation of the maximum kinetics of spontaneous and activated secondary radicals, reduction of the total production of secondary radicals in the antigenic activation of blood cells in vitro and an increase in the volume of spontaneously produced primary radicals.
Mathematical modeling of the magnetic field of red blood cells in narrow capillaries
Authors: Kopyltsov A V 
Published: August 2019

Abstract
The red blood cell (RBC) moves in a narrow capillary and asymmetric of its shape lead to tank-treading motion of the membrane. Electric charges on the RBC membrane generate a magnetic field in the surrounding space. A mathematical model imitating the motion of RBC through capillaries with a diameter less than 8 μm is developed in order to estimate the distribution of plasma pressure, plasma velocity and magnetic field strength in the vicinity of RBC. It is assumed that plasma flow between erythrocytes in the capillary satisfies the Poiseuille law, and in the gap between the capillary wall and the RBC membrane satisfies the Reynolds system of equations for the lubricating layer. Calculations made on a computer allow us to estimate the shape of the RBC, the speed of rotation of the RBC membrane, the plasma pressure, the plasma velocity and the magnetic field strength in the vicinity of the RBC. It is shown that the distribution of the magnetic field strength in the vicinity of the erythrocyte is non-uniform and depends on the capillary diameter, RBC speed, RBC charge, volume and surface area of RBC.
