Improving the heat treatment process of the underutilized fish raw materials of the Northern Basin
Authors: Golubeva O A , Astramovich V L , Zhikhoruk A A , Malaeva A V
Published: August 2019

The extent of dehydration of raw fish being blanched depends on the method and the mode of blanching and determines the area of their application. Stingray stellate meat is a valuable raw material for the fish foods production, since its protein contains all essential amino acids not synthesized in the human body. The main obstacle to the intensive industrial use of stingray stellate meat is the necessity to remove urea. The removal of uric acid is only possible in its thermal decomposition at temperatures above 60 °C. Mixed blanching (water-steam) can significantly expand the range of the loss of the raw material mass from 11 to 30 % compared to blanching with steam or water when removing the urea. The developed mathematical models for determining the basic parameters of the process of mixed blanching of stingray stellate are adequate and can be used for the predictive calculations. The developed modes of mixed blanching of stingray stellate are experimentally confirmed and can be recommended for the industrial use.

Authors: Batanov S D , Starostina O S , Baranova I A
Published: August 2019

Examination of body conformation traits and measuring of cattle exterior parameters play a significant role in improvement of animal’s breeding abilities and enhancement of selection efficiency. Non-contact remote measuring through the use of digital technologies means considerable progress towards mitigation of animal’s critical reaction to stress and substantial time reduction in contrast to manual measurements in contact with animals. This article presents a new approach to exterior assessment and provides an analysis of non-contact methods of measuring basic parameters of animals’ body conformation. The values of conformation parameters have been obtained by photo image processing of animals and with depth sensor. Basic body measurements (height at withers, height at rump, chest depth, chest width, rump width, rump length, body length, metacarpus girth) were taken in the production environment. They were determined with the accuracy up to 1 mm and an error about 2 %. Experimental findings show that these techniques may be considered as an innovative method of non-contact measuring of cattle conformation traits.

Published: August 2019

The aim of the work is a comparative assessment of the technological level of high-power wheeled tractors in the natural-industrial conditions of the Eastern agrozone of the Siberian Federal District. As the main criterion for adaptation to natural production conditions, when forming models and algorithms for assessing the technological level of Russian-made production tractors of different configuration, we used a generalized net performance indicator corresponding to the minimum reduced costs for different classes of rut and groups of tillage operations with specific characteristics of specific traction resistance of working machines and the nominal values of technological speed. According to the simulation results, rational traction modes were defined, limited by 7-15% skidding of propulsions and the corresponding change ranges and axle distribution of wheeled 4K4b tractors of different configurations. For the prevailing class of rut length more than 1000 m, the required tractor power, taking into account the employment in operations of different groups, was 260 kW on single wheels and 250 kW doubled with an operating weight of 14.64-17.60 t and 15.70-18.38 t respectively. With an average for the agrozone, the rut length class of 600–1000 m, the optimum values of the mass-energy parameters of the tractor are at the level of 0.80–0.81 from those indicated. According to the criterion of the technological level in the natural production conditions of agrozones with a rut length of more than 1000 m, the Kirovets tractors of models K-740P, K-742C and K-742P with an operating capacity of 284-298 kW on single wheels and tractor RSM-2375 (240 kW) on dual are mostly efficient (Kэ≥ 0, 950). Doubling the tractor wheels increases productivity by 5-6% and fuel efficiency of the aggregates up to 14% with a two-fold decrease in pressure on the soil.

Published: August 2019

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.

Published: August 2019

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.

Published: August 2019

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.

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

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.

Mathematical modeling of the magnetic field of red blood cells in narrow capillaries
Authors: Kopyltsov A V
Published: August 2019

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.

Published: August 2019

In the field experiment in the conditions of the Krasnoyarsk forest-steppe, the influence of resource-saving technologies on the physical state of agrochernozem and the carbon reserves of organic substance is studied. It is shown that the productive moisture reserves are satisfactory, in the subsoil layer there is a tendency to increase the moisture reserves by 2-5 mm on the minimum and zero background compared with plowing. Moldboard plowing and minimal tillage by fluffy consistency determined the greatest degree of differentiation of the humus horizon. Resource-saving technologies of main tillage contributed to an increase in bulk density by 0.05-0.08 g/cc while retaining the optimal parameters. The method of the main tillage determined the stocks of the above-ground mortmass. The stock of plant residues on the soil surface at the minimal background increased 1.4 times, at zero - 2.1 times compared with plowing. Stocks of phytomass, roots and underground mortmass were not identified by crop cultivation.

Authors: Stafford V V , Strel’tsova Ya B
Published: August 2019

The paper presents data supplementing the pathogenesis of porcine viral reproductive and respiratory syndrome. It was shown that the pathological changes taking place are characteristic both for animals infected under natural conditions and for experimental infection of piglets. Pathological data reflecting the development of pathology in the skin and in the internal organs of piglets indicate the development of systemic pathology affecting the hepato-linear, immune, respiratory and vascular system. The use of specific staining for fibrin showed its effect on the development of pathology not only in the respiratory system, but also in immunocompetent tissues. Specific staining for fibrin in histological sections of lung and lymph node tissues made it possible to determine that “young” fibrin coagulates in the tissues for 6 hours and becomes yellow-orange; “Mature” fibrin stays longer in the body for up to 24 hours and is painted depending on the period in orange-red (6-12 hours), bright red (12-18 hours) and red-violet (18-24 hours), then turning into the “old” fibrin, which is painted in purple (more than 24 hours) and grey-blue (more than 48 hours).

The influence of various types of fallow on the fertility of the textural carbonate agrochernozem and wheat yield in the conditions of the forest-steppe zone of Tuva was studied. It is shown that in the forest-steppe natural-climatic zone of the region of sideril fallows, the green manure melt fallow has the highest efficiency. In the forest-steppe in dry years, one of the best predecessors is pure fallow, but the highest yield of spring wheat was obtained after pure fallow with the introduction of manure and green manure traverses. The economic efficiency of various types of fallows in the territory of the Tuva Republic has been determined.

The basis of the study was the assumption that the nanoparticles of biogenic ferrihydrite exhibit biological activity in relation to plant organisms, which can be used in the cultivation of agricultural crops. The research studied the effect of nanoparticles of biogenic ferrihydrite on the development of seeds and seedlings of Lepidium sativum. Structural indicators were studied: masses of the aerial and root parts, linear dimensions of the above ground and root parts of seedlings. The activity of the photosynthetic apparatus was assessed by the relative index of the delayed fluorescence of chlorophyll seedlings of watercress. The germination energy and germination of seeds were investigated. The most pronounced effect of nanoparticles is registered in the increase in the total phytomass of seedlings and the length of the above ground part. A slight decrease in the photosynthetic activity of watercress sprouts was noted. The effect of nanoparticles of biogenic ferrihydrite on seed germination was not manifested.

Feline Leukemia Virus (FeLV) belongs to retrovirus family, causing various proliferative and immunosuppressive diseases in felines. There are two forms of FeLV: endogenous (enFeLV) and exogenous (exFeLV), the latter has 4 subgroups: A, B, C and T with different receptor specificity. The FeLV-A is the most abundant transmissive form. The FeLVB emerged as a recombinant between provirus FeLV-A and endogenous virus of domestic cats. The FeLV-C appeared as a result of accumulation of mutations in the env FeLV-A gene. The chimeric FeLV-T virus was obtaind as recombination event between 61E and 61C viruses. This review also covers two new recently described subgroups - FeLV-D и TG35.

The aim of the research is to study the effect of “Therapeutic and preventive immunoglobulin” immunostimulant on the veterinary and sanitary assessment of meat and the histological features of the parenchymatous organs of cattle. The study showed that pH of the meat in the experimental group was 5.32±0.03, in the control group – 5.43±0.02, the level of amine ammonia nitrogen – 1.19±0.02 and 1.21±0.01 mg in the experimental and control groups, respectively. The peroxidase reaction was positive both in the experimental and control groups, the reaction with copper sulfate was negative. The copper content was 34% more in the experimental group than in the control group (1.80±0.03 mg/kg). The concentration of zinc was 38.5±1.32 and 23.1±0.98 mg/kg in the experimental and control groups, respectively. The levels of iron were similar in the experimental and control groups. The cobalt content in the meat of calves in the experimental group was 24.6% higher than in the control group. The concentration of selenium and magnesium in the meat of calves in the experimental group was higher than in the control group. Such heavy metals as lead, cadmium, mercury and arsenic were not found in the meat of the calves in the experimental and control groups. According to the results of the histological study, the drug does not cause pathological changes in the structure of the liver, kidneys, myocardium, lymph nodes and spleen.
