Abstract
The goal of the study was to investigate the distribution of tagged wild reindeers on the territory of Evenkiya and to provide recommendations on preserving and rational use of the population. The study was performed in 2015–2016 by the Department of Hunting Resources Research and Nature Reserve Management of the Siberian Federal University. The relocations of 10 wild reindeers equipped with Argos satellite tags were monitored, land and aerial surveys of the reindeers were also performed. Besides, taxation and cartographic documents of the State Hunting Register, as well as information received from hunters and hunting providers were used during the research. The areas of divisions were delimited mostly with the help of GIS-technologies. The borders of habitats, their size and the character of animal moving were found through signals received from satellite radio tags. To assess the behavior of the animals, the speed of their movements was analyzed both by the azimuth straight line between two daily points and by a tortuous trajectory. The maximum duration of signal from collars with new battery blocks in 2015-2016 was 438 and 444 days. The total distance covered by reindeers by the beginning of the third decade of July was 1641.1 km from locations of tagging, according to the satellite positioning data. The average speed was 13.5 km per day. A radical decrease in the number of tagged reindeers occurs with the beginning of spring migration. Two large waves of reindeer migration with an interval of 20–26 days have been observed in recent years. The positioning of tagged animals provides objective information on the migration of the herds, their fawning and wintering grounds. The possibilities of using a database for complex quality assessment of the population size and location of reindeer resources of Yessey group, as well as features of their habitats, are discussed in the article, with the biotic, abiotic and anthropogenic factors being taken into consideration.

Abstract
One of the methods for investigating complex mechanisms of pathological process development in the body is biological modeling. Absence of standardized reproducible experimental models makes comparative assessment of multiple drug efficacy studies including in case of liver diseases much more difficult. Among experimental toxic lesions of the liver, the model of liver lesion induced by tetrachloromethane in mice is widely spread, which has considerable drawbacks. So, for certain tasks it becomes necessary to work with other animal species, in particular, with rabbits. Modeling of acute and chronic lesion of liver was done by intraperitoneal administration of 50 % carbon tetrachloride olive oil solution based on 1 ml per kg of body mass twice a week. In the course of experiment, on day 5 rabbits develop toxic lesion of liver supported by hematology examination. Hepatic functional insufficiency was characterized by hypoproteinemia, dislipidemia, statistically significant increase of serum transaminase activity, total bilirubin. Ultrasound, x-ray, morphological analysis of liver tissues in experimental rabbits showed changes consistent with hepatitis signs. Thus, this investigation has demonstrated that use of rabbits as a model gives a number of advantages: the possibility of studying biochemical markers in dynamics, ultrasound and x-ray monitoring of lesion.

Abstract
The article analyses some factors of rational nature management. The concept of the rational is specified. The prospects of explication of this concept not only in the epistemological aspect but also in the sociological, praxiological and axiological aspects are shown and essential characteristics of rationality are revealed. The main conclusions of the study are that the rational improvement of the mechanism of environmental management inevitably involves humanisation of all spheres of society: social economic, political, managerial, educational, etc. A fundamental regulator of human activity in the field of environmental management is the ethical component that contributes to the implementation of the principle of co-evolution in the relationship between man and nature and the development of optimal factors of environmental management.

Published: August 2019

Abstract
The possibility of fixing genotoxic changes in Saccharomyces cerevisiae yeast under the influence of physicochemical factors was evaluated using the DNA-comet assay. Peripheral blood leukocytes of mice subjected to similar effects were used as an object of comparison. The data obtained showed that under the action of both the alkylating agent and X-ray irradiation, the changes were more pronounced in experiments with leukocytes of the blood of mice. At a methyl-methane sulphonate concentration of 10 mM, the comet tail length in mouse peripheral blood leukocytes was about 40 μm, while the yeast spheroplasts tail length of a comet was 0.16 μm. The DNA content in the tail of the comet did not exceed 5 % for yeast after treatment with an alkylating agent at a concentration of 40 mM, which is 10 times less than in peripheral blood leukocytes of mice under similar conditions. Under the action of X-ray radiation, the length of the comet’s tail and the DNA content in it for spheroplasts of yeast also differed significantly from the leukocytes of the peripheral blood of the mouse. Thus, the comet test allows to register a significant increase in the level of DNA damage in yeast spheroplasts under the action of physicochemical factors in relatively high doses.

Abstract
The development of milk horse breeding in Russia contributes to the high genetic potential of heavy draft stud mares. The Republic of Mari El has been breeding heavy draft horses to produce koumiss since 1977. The efficiency of heavy draft horse breeding depends on the intensity of use of the breeding stock. At the same time the duration of economic use of animals is of great importance as the duration of the use of horses provides not only economic benefits but also the breeding progress of the herd. The studies on duration of economic use of Lithuanian heavy draft stud mares and their lifetime productivity were conducted on the Koumiss farm of ZAO PZ “Semenovsky” of the Medvedevsky region of the Mari El Republic. The studies have shown that the duration of economic use of Lithuanian heavy draft stud mares on the farm is 4, 195 days or 11.5 years on the average. The study of the lifetime productivity revealed that the Lithuanian heavy draft stud mares had a high lifetime milk yield. As a result of the research the significant positive correlation between the duration of use of the mares and their lifetime milk yield was found out. There is a small positive correlation between the duration of economic use and 1-day milk yield of the economic use and 1-day lactation. The analysis of duration of economic use of Lithuanian heavy draft stud mares depending on their father’s genotype has showed that the longest lactation in the herd was among the daughters of stallion Sunkumas 32 – 15 years. Thus, when conducting selection and breeding work, the farms have great possibilities to increase the period of economic use of horses on this farm and increase their lifetime productivity.

Abstract
New varieties of spring triticale were taken an assessment in the conditions of the Republic of Chuvashia. It’s elicited that Saur variety is characterized by the biggest number of productive footstalks with kernel weight per spike and thousand-kernel weight. Variety Rovnya had the least number of productive footstalks. This variety showed minimal number of spikelets in a spike. At the same time, Rovnya had the biggest amount of grains. Variety Ulyana was inferior to all other varieties in kernel weight per spike and thousand-kernel weight. Variety Khaikar true of fact exceeded the standard in the number of productive footstalks, kernel weight per spike and thousand-kernel weight but in the number of spikelets and seeds in a spike was equal to Ulyana. The varieties Saur and Khaikar exceeded the standard in crop yields. Field germination rate turned to be rather low. In fact, Ulyana’s seeding rate has not affected the index. It fluctuated from 56, 0-56, 5%. Seeding density depended on both seed application rate and the variety itself. Number of seedlings with seeding rate growth increased of Ulyana variety from 225 to 339 and 276-372 pcs / m² of Khaikar. However, with increase of the seeding rate the survival capacity and viability of plants decreased. Especially sharp decline was common to the seeding rate of 6 ml of germinating seeds. Optimal seeding rate of triticale varieties in Chuvashia is 5 ml per 1 ha.

Abstract
The effect of the nature of the silicon source on the physicochemical properties of synthesized zeolites and the activity of Zn-containing catalysts prepared on their basis in the course of conversion of the propane-butane fraction into aromatic hydrocarbons is studied. It is shown that the silicon source plays an important role in the hydrothermal synthesis of zeolite. It has an effect on the duration of synthesis but its effect on the physicochemical characteristics of the resulting product is minor. It is established that the activity and selectivity of Zn-containing catalysts for the aromatization of lower alkanes are practically independent on the nature of the silicon source used in the synthesis of the high-silica zeolite, which is an acid carrier of these catalysts.

Published: August 2019

Abstract
The authors obtained two-phase samples of silver- and zinc-modified hydroxyapatite (AgHA, ZnHA) by liquid-phase deposition under microwave exposure; the main phase for all samples was hydroxyapatite Ca5(PO4)3(OH) with hexagonal syngony. The parameters of the elementary lattice of HA were studied via X-ray phase analysis and confirmed the formation of solid substitutional solutions while modifying HA with silver and zinc ions. Solubility has been estimated at 20 ºC for a 0.9% NaCl solution; specific surface area and porosity have been estimated for ZnHA powders obtained in presence of aminoacids. Surface morphology and dispersiveness have been studied for AgHA and ZnHA powders. Hammett method helped to establish the presence of acidic and basic centers on the surface of ZnHA and AgHA. Koch biotesting showed HA, AgHA, and ZnHA acting as inhibitors thus affecting E. coli tested samples. HA, AgHA, and ZnHA powders can be recommended for medical purposes.

Abstract
Physicochemical and catalytic properties of 4.0% Mo/ZSM-5 catalysts manufactured on the basis of zeolites with a hierarchical pore system are investigated. The effect of the conditions of synthesis of zeolites with an additional mesoporous structure on their textural and acidic characteristics is studied. The structure and morphology of crystals of synthesized zeolites and catalysts produced from them are determined by the methods of X-ray diffraction analysis and high-resolution scanning transmission electron microscopy. It is shown that 4.0% Mo/ZSM-5 catalysts produced from zeolites with a mesoporous structure exhibit higher activity and stability in the course of methane dehydroaromatization.
