Published: September 2020

Abstract
Microelement composition in a diet influences the morphology of duck liver is described. Microelement composition of the duck food was studied in accordance with GOST (State Standard Specification), which states the selenium content amounting to 0.06 mg/kg for the growing ducks and 0.14 mg/kg for adult ducks. The experiment on Pekin ducks aged from 1 to 120 days implied that the control group received basic diet and the experimental group received DAFS-25k (Diacetofenonilselenide) in accordance with the product instruction during the whole period of raising. The studies were undertaken at an interval of 15 days. Liver structure of one-day ducks had typical anatomy. Connective tissue was moderately marked, tubular structure was clearly marked, hepatocytes had polygon shapes, the nuclei were oval or round, located centrally, they contained from one to four nucleoli. Vacuolated cytoplasm was observed for 15-day ducks from the control group. For the experimental group: hepatocyte nuclei had the same size, cytoplasm was homogeneously coloured, sinusoidal capillaries with red blood cells were clearly marked. In critical periods of raising, namely on the 30th day, when neoptile was replaced with primary plumage, and on the 75th day, during post-juvenile moult, for the control group we could observe granular cytoplasm structure, which is a characteristic feature of granular degeneration; for the experimental ducks: liver structure had definitive structure, morphofunctionally active. For 120-day ducks from the experimental group: the liver retained its tubular structure, had singular fat build-ups; for the control group: clear signs of hepatosteatosis. DAFS-25k did not have negative influence on morphofunctional activity of the organ; the selenium content in the liver of 120-day ducks from the experimental group amounted to 0.52 mcg/kg compared to 0.31 mcg/kg for the control group.

Abstract
Increasing the intensification of herd reproduction is one of the main ways of increasing the number of beef cattle, increasing beef production, and reducing its cost. The main task in the reproduction of the herd is the annual receipt of a viable calf from each cow and heifer. One of the methods to increase reproductive functions is the use of hormonal drugs, analogues of sex hormones. Synthetic hormonal preparations in dairy cattle breeding are used to synchronize sexual hunting, ovulation and calving, to intensify the sexual functions of uterus (inducing superovulation, shorten the service period, etc.) and to treat pathologies of the ovaries, endometritis, and other disorders of the sexual apparatus of cows and heifers. The article presents the results of applying two synchronization schemes of sexual hunting in Holstein cows in an industrial dairy farm. In the first group, the Pre-synch scheme was used, in the second – «Ovsynch». The schemes differed in that the «Pre-synch» is longer and more costly, but it begins to be used from 21 days after calving. According to the results of the synchronization of sexual hunting of both groups, results were obtained on milk productivity. In the first group, baseline fat milk was produced for 305 days of lactation, 9411.0 kg of milk, in the second - 7785.0 kg. Considering all the costs of synchronizing sexual hunting in Holstein cows, profitability in the control group was 24.8%, in the experimental group - 19.2%.

Abstract
Massive contagious diseases (epidemics, pandemics) that quickly spread over large areas and can migrate from one country to another have been studied by such scientists as E. Johnner (1796), P. Louis (1879), I. Mechnikov (1883) and others. I. Mechnikov the immunity to infectious diseases associated with innate and acquired immunity. In turn, both innate and acquired immunity can be natural, if immunity is acquired as a result of a disease, or artificially acquired as a result of preventive vaccinations or the administration of artificial sera. In early 2020, the World Health Organization announced a pandemic of a new coronavirus infection due to its rapid spread in 170 countries. A person can be infected with coronavirus through different biological media, but first of all it is a respiratory disease. Coronavirus CoVID19 is a further mutation of the virus strain–SARS-pneumonia, also known as SARS-CoV-2. COVID19 contains 16 unstructured and structured proteins and has a large genome. Two models of solving the problem with COVID19, adopted in different countries, are considered: the first is complete self-isolation; the second is partial isolation of people with compromised immune systems. A graphic chart of the state and transition model of the Virus Source, Viral Vector, Recipient and Environment (CoV-E-V-P) system was constructed and analyzed. The change in human health state under the influence of the element parameters of the system is researched. The functional structure of the information model for monitoring and decision management system CoV-E-V-P is designed.

Abstract
In the scientific and practical fields of dairy farming a lot of attention is given to pathologies and diseases of cow’s mammary gland. Mastitis, as a nosological unit, is an actual targeted direction for many researchers. The development of preventive and therapeutic medicines based on bacteriophages is a promising and demanded direction in dairy farming. In the course of work was shown reactogenicity of mammary gland after the intracisternally administration of viral antigen. It was manifested by vividly expressed clinical signs of serous-fibrinous inflammation. The described reaction is very similar to the manifestation of a non-specific antiviral immune response. It was noted the dose-dependent intensity of the somatic reaction and clinical manifestations of a non-specific response when inactivated bacteriophages were administrated. The clinical manifestation of a non-specific protective antiviral mechanism of the mammary gland in response to the administration of bacteriophages was shown too. Method of phage-mediated sensitization of the mammary gland was proposed for the first time.

Published: September 2020

Abstract
This article shows that the number of biotic taxa in the region depends on the drought index. From the very beginning, in strict conformity with the drought index, the number of biotic taxa increases from tundra to the border of taiga and forest steppe, where it reaches its maximum, and then it decreases towards the steppe zone. The authors note that the interaction between the components of the biota is characterized by two basic indicators: degree of harmony H and stability Z. The analysis of the state of biotic systems based on the use of these indicators clearly reflects the level and potential for their functioning. These results generally demonstrate the unity and interdependence of plants and animals and the dependence of both on climate.

Authors: Savchenkova I P , Savchenkova E A , Osipova Yu A , Yurov K P 
Published: September 2020

AbstractMacrophages derived from pluripotent stem cells represent an attractive cellular system for the study of lentiviruses. The possibility of obtaining cells with a phenotype similar to macrophages in the process of differentiation of mouse embryonic stem cells (ESCs) in the presence of the conditioned medium (CS) from bone marrow-derived stromal cells or interleukin 3 (Il-3) and macrophage colony-stimulating factor (M-CSF) was demonstrated. The results of flow cytofluorimetry showed that the replacement of CS with recombinant cytokines in induction media contributed to an increase in the number of cells positively stained antibodies (AB) against AG CD34 by 8% and CD45 by 20%. When seeding such cells in a methylcellulose medium supplemented with CS or a mixture of Il-3 and M-CSF, the formation of colonies with different morphology, including monocyte/macrophage, was observed with an efficiency of 0.11 % and 0.33%, respectively. The percentage of positively stained cells AB against F4/80 AG was 8±0.02 %. The cells demonstrated the ability to non-specific phagocytosis of latex particles. Thus, it is shown that it is possible to obtain cells with a phenotype similar to macrophages from mouse ESCs during differentiation, and the advantage of using two recombinant cytokines for this purpose is established.

The influence of chemical soils composition on the thermodynamic probability of the air nitrogen fixation
Authors: Podshivalova A K 
Published: September 2020

Abstract
According to the simulation results, the oxidation of air nitrogen in soils to the highest degree of oxidation (nitrate ion) is thermodynamically possible. Clay soils are favorable for the process of air nitrogen oxidation. Sandy soils are inert in this respect, and the processes occurring in them are determined by other participants of the studied thermodynamic systems. Soils containing limestone and slaked lime are characterized by the highest efficiency of fixation of air nitrogen. The thermodynamic probability of air nitrogen binding depends not only on the type of the main component of the mineral fertilizer, but also on the degree of its oxidation in the composition of the corresponding compound. The presence of nitrogen (+5) in the simulated systems creates thermodynamic prerequisites for reducing the energy barrier of the limiting stage of air nitrogen oxidation.

Abstract
The growth indices of the 56-year-old Siberian cedar, which grows in forest crops under the forest stand canopy of Pinus sylvestris and Betula pendula when the canopy closed 0.1–0.4; 0.5-0.7; 0.8-0.9 and the number of survived specimens in the sites (from 1 to 8 pcs.) in the suburban area of Krasnoyarsk. Initially, in each area measuring 0.7×0.7m, 9 pieces of four-year-old seedlings were planted under the Kolesov’s planting iron, placing them at a distance of 20 cm. There is a distance of 4 m between the centers of the sites. It was found that indicators of leading trees such as height, diameter of the trunk and crown significantly decrease with increasing closeness of the canopy (the share of the influence of canopy on the height of the leading trees amounted to 84.8%, to the barrel diameter - 91.3%). The share of the influence of the number of Siberian cedar trees preserved in the sites on the indicators of leading specimens is insignificant and amounted to 3.9% in height and 1.7% in trunk diameter. The creation of Siberian cedar cultures is recommended with a lesser density of the forest stand canopy or in an open area.

Abstract
The article assesses the nature of the impact of environmental problems on biotechnology associated with changes in humoral factors (level of neuron-specific enolase in association with hormonal factors) during the formation of chronic abnormal conditions in conditions of environmental trouble. The possibility of using neuron-specific enolase as a predictor of these conditions has been proved. The quantitative values of neuron-specific enolase for predicting the risks of developing chronic abnormal processes in the presence of ecological problems have been established. The connection of these processes with the formation of endocrine dysfunction against the background of an increase in the level of neuron-specific enolase has been proved.

Published: September 2020

Abstract
One of the really effective options which can significantly improve the performance of harvesting machines is the equipment of the combing harvester reapers. A significant reduction of the technological mass of the straw entering the threshing device of the combine, reduces load and wear on the working elements of the threshing apparatus and allows for combing at higher speeds. Production costs on the option of direct harvesting has increased with great fuel consumption during the harvest of winter wheat. According to variants of the production costs amounted to 14911.4 when cutting and 14616.9 in the combing plants. The use of harvesting of grain crops by the method of combing increases the profitability of the resulting product. In direct combining, the level of profitability amounted to 63.4 %, when using combing plants – 66,2 %. The combing of the device confirmed its high efficiency, especially in high humidity conditions. The decrease in grain moisture contributed to yield reduction. When harvesting winter wheat with a grain moisture of 16% yield of 3.4 t/ha and 3.3 t/ha, respectively. When comparing two methods of harvesting the difference in yield was 0.2 t/ha. Account yield in the variant with the grain moisture 9 % obtained the following data: in the direct harvesting of 3.1, while the tops of plants of 3.2 t/ha. Sharp decline in the yield suggests that grain moisture 9% is critical in any way of harvesting losses increase significantly due to shedding of grain heap.

Abstract
To clean the industrial company air substances of the semiconductor electronics production is a necessary procedure to lower the atmosphere technical load. The hazardous substances of soldering and montage works are some metal oxides and aerosol substances, which simultaneously circulate in a production in its vapor and gas forms. To evacuate those hazardous substances from the production equipment is done through the tide and extraction ventilation channels, which transport the contaminations into the center filtering system. There is a scheme how to collect the hazardous production substances in an electronics production. The center filtering system contains of some engineer cyber-systems (ECS) to neutralize the contaminations with absorbing and adsorbing ecological means and also with catalyst methods. There is a scheme of center filtering aggregates to neutralize the contaminations using ECS. The production and ECS synchronous interaction must be provided with the intellectual environment resources to support the nature safety technologies to minimize the technical influence on the environment.

Published: September 2020

Abstract
The problem of damage and infestation of forests by pests and diseases takes a significant place in forestry. The combination of these factors, taking into account cutting and harm to forests from fires and other human activities, as a result leads to tremendous degradation of forest ecosystems. In modern conditions, the forest pathological stands condition in Russia is determined on the basis of data from forest pathological surveys and state forest pathological monitoring. For the current period (2020), disappointing statistics remain on the reproduction of the Siberian silkworm population (Dendrolimus superans sibiricus Tscetv.) nd the negative consequences for taiga forests. Modern climatic changes on a planetary scale have a significant impact on mass outbreaks of dangerous phytophage. In the near future, adaptation measures in the field of forest pathological monitoring should be based on risk factors when planning forest protection measures, a diverse selection of adaptation options and adopting a flexible forest management system at the regional level. In this paper, we consider one of the methods for improving forest pathological monitoring, based on the principles of covering as large a territory as possible with remote sensing data (ERS) combined with predictive models based on GIS that allow predicting the risk of mass reproduction of the Siberian silkworm based on the previously studied factorial dependence.
