Authors: Ulyanova O A , Kurachenko N L , Vlasenko O A 
Published: August 2019

Abstract
In the field experiment with the agro-gray soil of the Krasnoyarsk forest-steppe, the improvement of the agro-physical properties was established with the use of organic fertilizers, regardless of their type and application rate. Under the influence of bio-fertilizer and chicken manure introduced into the agro-gray soil, there is a tendency to increase the amount of humus and nitrate nitrogen, mobile phosphorus and the yield of wheat grain. The correlation between the yield of wheat grain and mobile forms of humus is estimated at the average level. Using the method of multiple regression, a model of wheat yield was calculated, according to which it depends on the content of mobile humus substances.

Abstract
A field experiment was conducted at an agro-ecological station (53 ° 33‘58.75 “N and 102 ° 35‘23.90” E) of the Siberian Institute of Plant Physiology and Biochemistry on gray forest medium loam soil. Winter rye (family 6) and winter triticale (No. 430-6002) were sown in 4 terms with a 10-day interval (10, 20, 30 August and 10 September) in three replications. The results of the two-year studies show that the winter crops included in the experiment had a higher (higher than 5 t/ha) and more stable yield between the years with the planting dates held on August 20, 30 and September 10 for rye and August 30 and September 10 for triticale. Earlier sowing time contributed to intensive tillering, strong growth, which led to the plant death and lower yields.

Published: August 2019

Abstract
The article deals with the body adaptation of foreign students from warm countries to the sharply continental climate of the Volgograd region. By adapting to the new climatic and geographical conditions of study and living, there are changes in the physiological function of the life-supporting systems. On the basis of a differentiated approach to the assessment of the adaptive state of functional systems, it is possible to identify groups with “poor adaptation of functional systems”, with “stress of functional systems by adaptation” and with “satisfactory adaptation of functional systems”. The factor structure of adaptation has been determined, including: the hormonal factor, the oxygen transport cascade factor, the vegetative supply factor, the respiratory homeostasis factor, the acid-base and gas composition factor. Imbalance and inadequacy in the activity of life-supporting systems, strengthening the central contour of cardiac activity regulation, changes in peripheral blood, hormonal status are criteria for an unfavorable course of adaptation processes in the body. Functional adaptation of the body of foreign students is influenced by the factors of a new climatic and geographic environment and educational activities features.

Influence of the seeding rate on the formation of anatomical features of the monoecious hemp stems of Diana breed
Authors: Dimitriev V , Shashkarov L , Mefodyev G 
Published: August 2019

Abstract
The article considers the research results on the influence of the seeding rate on formation of anatomical features of the monoecious helm stems of the Diana breed. According to the experiment scheme, the seeding rate is from 0.1 to 2.7 million pieces of germinating seeds per hectare. The size of each plot is 10 × 10 m (100 m2). The tier is 3-fold. Nature of the change in the thickness of the bast-fibered layer depending on the seeding rates was studied. The results of the research showed that the thickest bast-fibered layer (530.5-636.4 μm) is formed due to the seeding rates of 1.8–2.7 million pieces / ha. Thus, there is a reason to assume that the increased seed rates allow achieving the best yields indicators of the bast-fibered substances. It is noteworthy that each seeding rate is characterized by a certain amount of elementary fibers in the stems: stems from crops with the seeding rate of 0.1–0.6 million pieces / ha have the smallest number of primary and secondary fibers. The largest cells of primary and secondary fibers are found in the stems from crops with the seeding rate of 0.1–0.6 million pieces / ha, the smallest - due to the seeding rate of 1.8–2.7 million pieces / ha. Consequently, the size of both primary and secondary fibers decreases when the seeding rate is increased. The data of the research conclusively prove that the size of the inner lumen of the elementary fibers decreases both lengthwise and edgewise when the seeding rate is increased. Stems that are grown on the plots with the seeding rate of 1.8 -2.7 million pieces / ha have a thick bast-fibered layer (530.5–636.4 μm) with the largest amount of primary and secondary fibers (6918, 4-8302.6 cm) of a regular multi-faceted shape with a small internal lumen lengthwise and edgewise (2.9–4.2 μm and 2.2–2.7 μm).
Cost-effective reducing the environmental impact of wheat production in Siberia
Authors: Keler V V , Khizhnyak S V 
Published: August 2019

Abstract
The effects of previous crop, fertilizers and pesticides on the wheat yield and the cost efficiency of wheat production in Siberia were studied in two-year field experiment. It was found that the yield mostly depends on the previous crop and pesticides, whereas the fertilizer demonstrated relatively slight effect in the year favourable for wheat growth and no effect in the year unfavourable for wheat growth. Cost-effectiveness analysis showed that the most effective way to reduce the environmental impact of wheat production in Siberia is the use of fallow in crop rotation scheme. Usage of fallow without chemical fertilisers provides higher yield than variants with fertilisers and pesticides where wheat was used as a previous crop. Cost efficiency of variant with fallow was 20.8% what is comparable with cost efficiency of the most cost effective variants (fallow as a as a previous crop + pesticides with cost efficiency of 36.6% and wheat as a previous crop + fertilizers with cost efficiency of 30.4%).

Published: August 2019

Abstract
In order to solve the urgent problem of the development of forest transport systems efficiently, it is necessary to develop strategic principles for their planning, taking into account the current realities of a market economy and the transition of the world community and Russia to the principles of sustainable development. Formation of transport systems in general and the new road network on the territory of forest lands in particular requires significant financial and material resources and therefore it is important to justify the cost effectiveness of their creation and development, taking into account the principles of sustainable development of the territories and the overall environmental and socio-economic effect of the implementation of state project. The paper substantiates the need to take into account environmental, social and economic factors when planning transport systems on the territory of forestland. The principles for assessing ecological and socio-economic efficiency are proposed. Quantitative efficiency criterion is developed taking into account the principles of consistency. The developed objective function of the optimization problem reflects the profitability of the timber transport system (including costs for all stages of its life cycle) for the entire planned period of interaction with the forest ecosystem, i.e. recoupment of the design, construction and operation of the forestry fund of the country’s regions by achieving the maximum productivity of the forest ecosystem from their coexistence over the entire planning period.

Published: August 2019

Abstract
The article discusses the issues of the interaction between indigenous peoples and business in environmental management in the context of the Arctic development. The author analyzes the current legislation on environment management related to the subsoil users and indigenous peoples, gives case-studies of such cooperation during mining. The implementation of corporate social responsibility during the interacting of indigenous peoples and business is considered in the paper, including investments in the development of social infrastructure, education, employment. It also discusses the main objectives of the development of the Arctic territories, which include improving the welfare of the population, solving social and economic problems. The author proves that research on the development of approaches and mechanisms for coordinating interests in traditional lands is relevant, since each stage of the investment project should include a set of tools and methods aimed at the negotiation process, the calculation of damage, monetary compensation, etc. Based on a study of statistical and legal data, the author justifies the need to develop mechanisms for cooperation and partnership between business and indigenous peoples to achieve the goals of sustainable development of the territory.
Biogeochemistry of honey chemical elements
Authors: Pashayan S A 
Published: August 2019

Abstract
The quality of honey is reduced due to the fact that various insecticides and residues of acaricides fall into it. This is due, on the one hand, to frequent violation of instructions on the use of drugs - time of use, dose, frequency of processing and intervals between them, on the other hand, it is necessary to take into account the state of bee colonies and their nests. Violation of these requirements may lead to the ingress of toxic substances into food honey, as well as changes in the normal functioning of the metabolism in the body of insects.

Published: August 2019

Abstract
The authors of the article determine the phytoxicity of aromatic hydrocarbons in various concentrations in relation to some agricultural plants and the ability of these plants to accumulate hydrocarbons. This is done for the first time on the basis of field studies of plantings at different distances from the enterprise for the production of carbon black, which is a source of gaseous saturated and aromatic hydrocarbons, as well as after exposure of these mixtures to methane, phenol, benzene and toluene. The objects of study were Phaseolus vulgaris, Hordeum vulgare and soft spring wheat called “Memory of Aziev”. Statistically significant changes in the pigment complex of plants, expressed in a decrease in the content of pigments and carotenoids, an increase in the ratio of b and a chlorophyll under the action of hydrocarbons were revealed. The activity of the polyphenol oxidase enzyme tended to initially increase, in response to pollution, and to a subsequent decrease under the action of higher concentrations and high toxicity of the gas. Plant peroxidase activity increased 1.5–7 times with an increase in the concentration of toxin in comparison with the control analogues. According to the degree of phytotoxicity, the studied gases are arranged in the following sequence: phenol > mixture of aromatic hydrocarbons > benzene > toluene > methane. Phaseolus vulgaris turned out to be the most sensitive to the action of hydrocarbons, and also capable of active absorption of hydrocarbons.

Authors: Semenov I E , Ivanov A V 
Published: August 2019

Abstract
This paper presents data on new designs of Russian solar collectors for hot water supply. Field tests of collector installations showed its high efficiency corresponding to the best foreign analogues. The main advantage of the collector is a low cost, which is achieved by using new methods of local processing. A new cost-effective production technology for a thin-walled heat-receiving panel allows you to produce channels of any shape. Based on the method of local deformation, the production technology of the panels made it possible to arrange their manufacture in Russia and reduce the weight of the panels and their cost by 30…45% compared with the best Japanese and German counterparts.

Published: August 2019

Abstract
The purpose of this research is to create a new way of making gluten-free foods. Gluten-free cereals acreages in Russia were analyzed. It was revealed that gluten-free cereals have much less acreages than wheat one which is why gluten-free food production in Russia is so poorly developed. It is suggested to use sorghum flour as gluten-free non-traditional raw material. Physical-chemical properties of sorghum flour were determined. Gluten-free biscuit, custard and chocolate cream were obtained. Determination of obtained products organoleptic properties was conducted by potential gluten intolerant customers.

Abstract
The paper is devoted to searching for alternative raw materials for the food industry. The purpose of this study is to develop a recipe and technology to prepare cheese curds coated with dried apricots. Conventional methods are used to study structural and mechanical parameters. The results obtained when investigating structural and mechanical indicators of fruit coating for cheese curds with the software package STATISTICA 6.0 are presented. The research involves regression and correlation analysis of experimental data. Based on the results we could determine the exact amount of each ingredient in the recipe for multicomponent fruit coating of cheese curds. A recipe and the stages of manufacturing process for the production of sweet cheese curds coated with dried fruit have been developed. The manufacturing process proposed for the production of cheese curds coated with dried fruit has a number of advantages in comparison with the traditional technologies for the production of glazed cheese curds. Replacing the chocolate glaze with dried apricots resulted in decreasing the cost of the cheese curds coated with dried apricots per 5 kg batch. Moreover, cheese curds with the fruit coating are a good source of complete proteins, fiber, vitamin C, and minerals.
Geochemical processes of mercury transformation in the river-sea system
Authors: Nguyen N T T 
Published: August 2019

Abstract
In this paper, the average concentrations of mercury in river water and suspension in seawater were presented. The authors gave the spatial distribution of mercury in the dissolved and suspended forms and in the bottom sediments. The studies were carried out at 30 stations twice a year (in the period of high water and low water) in the period 2014 – 2016. Samples of the bottom sediments were collected in the surface layer. The spatial distribution of mercury was performed by Kriging interpolation in ArcGIS 10.2.2. It was shown that the river flow is dominated by dissolved forms of mercury at the top and suspended forms in the mouths of watercourses, while the sea is dominated by dissolved forms. The geochemical transformation processes of the river sedimentary substance (dissolved and suspended forms of mercury) in the mixing zone of the river and sea waters (in the area of the so-called marginal ocean filter) have been studied in detail. It has been shown that, the marginal filter is characterized by flocculation of inorganic and organic dissolved substances with concomitant capture of dissolved forms of metals, which can lead to an increase in the proportion of mercury carried on the suspended substance. The content of suspended forms of metal was reduced due to the self-purification of the water system from the river material and the transition to marine conditions.

Published: August 2019

Abstract
To restore the shape of curved low-stiff cylindrical parts such as shafts and axles, the process of straightening by transverse bending is considered with subsequent hardening by the method of surface plastic deformation based on the transverse rolling of the cylindrical part with flat plates. The stress states of parts during editing are determined using the Ansys Workbench software package. The results of the distribution of the intensity of operating voltages and residual stresses over the cross section of the cylinder, depending on the absolute compression, are presented. The process in question can be implemented without the use of environmentally hazardous lubricating cooling technological means, which makes it possible to attribute it in the future to one of the types of green mechanical processing technologies.
Comparative economic characteristics of environmental protection tools
Authors: Veklenko V I , Soloshenko R V , Glebova I A , Nikiforov-Nikishin D L , Klimov V A 
Published: August 2019

Abstract
The relative advantages of the tools for the environmental protection have been assessed in the article. From the economical point of view emission taxes, subsidies for abatement of emissions, and market-based permit system are more preferable in comparison with the control and management systems. The control of emissions for each organization can be achieved only in case when the marginal costs of abatement for each pollutant are known, which is unlikely in practice. In case of immiscible pollution, the determination of the marginal costs of organizations to control emissions is not required only for permitting schemes, which gives them an advantage over other tools. The least expensive for achieving a particular purpose in the fight against pollution is the tool of minimum technological requirements for the protection of the environment. The long-term effect of the instrument depends on the net income effect and the effect of technological innovation. Subsidy schemes or alternative methods of initial distribution of market permits at the expense of positive effects of income can increase the size of the industry, which is undesirable from the ecological point of view. In order to neutralize this effect, the organizations of the subsidized industry may be obliged to make one-time payments, the amount of which is the total cost of subsidies. The second way is the induced impact on the pace of technological innovation. Control and management tools have weak incentives for innovation. An emissions tax (or emission control subsidy) will encourage environmentally sound innovation. In the market scheme, emission reductions reduce taxes. Pollution control instruments have different consequences for the distribution of income in the economy and the competitiveness of the economy.
