Authors: Saitov Viktor , Farafonov Vyacheslav , Saitov Aleksey
Published: May 2020

The aim of the research is to determine the effectiveness of ergot isolation and to estimate grain losses in waste when the cereal material is immersed in the stream material in water and an aqueous solution of salt of different densities ρzh from the specific grain load gsp. Practical experiments were carried out by feeding grain material of winter rye of Falenskaya 4 variety with a moisture content of 14% from a height of h = 60∙10-3 m into water and an aqueous solution of sodium chloride (NaCl) with a density of 1030, 1060, 1090, 1120, 1150 and 1180 kg/m3. The variation of the specific grain load gsp was carried out according to the values of 0.674; 1.469; 2,871; 4.449 and 7.221 kg/(s∙m), which corresponded to the opening of the outlet window of the bunker of the experimental setup 10.0; 15.0; 20.0; 25.0 and 30.0∙10-3 m. The temperature of ambient air, water and an aqueous solution of salt was 200C. It has been established that the density ρzh of an aqueous salt solution has a greater influence on the result of the technological process than the specific grain load gsp. At a density ρzh of the aqueous solution of the salt of 1150 kg/m3, there is a 100% emergence of ergot sclerotia on the surface of the solution, and the losses of the PZ grain to the waste do not exceed 2,52%, which corresponds to the agrotechnical requirements for the final grain cleaning machines.

Published: May 2020

The priority in improving the existing methods of processing fish is salting with the use of food additives with different functional orientations. The aim of the study was the development of preserves with the introduction of lactate-containing additives and using sonochemical technologies; examination of the quality of the products obtained according to organoleptic and microbiological safety indicators. The article proposes a resource-saving technology for the production of fish products with prolonged shelf life due to the use of a complex food additive consisting of lactic, acetic, propionic acids and their salts in different proportions with subsequent ultrasonic treatment using the ultrasonic generator of the Wave series model UZTA-0 2/22-OM. There was established the optimal mode of using the ultrasonic processing power of 75 W / m2 in the manufacture of fish preserves from herring. Organoleptic and microbiological quality indicators were studied during storage of preserved products with the addition of additives and ultrasonic treatment compared to the control. Organoleptic assessment was carried out on a five-point scale, microbiological indicators were studied by standard methods. The Dilactin Forte Plus dietary supplement in the composition of preserves in the amount of 3% and in combination with the use of sonochemical technologies makes it possible to obtain a safe high-quality fish product. Manufactured preserves at a storage temperature of 0 ± 2 ° C can maintain their high quality for 5 months.

Published: May 2020

The research was carried out with the aid of vegetation experiments and on saline soils in production crops of the Stavropol territory farms (Andropovsky, Mineralovodsky and Kochubeyevsky districts). The goal of the research was to identify patterns of germination and formation of sunflower seeds, depending on the influence of saline soils and the use of mineral fertilizers. It was found that sunflower seeds germinate at fairly high concentrations of soil salts. In vegetation experiments, where saline soil containing 1.14% and 1.71% of chloride- sulfate salts was used, the number of sprouted seeds was 96.0% and 89.3% of the unsalted background, respectively, 14 days after sowing. The salinization type has a various impact on seed germination. A greater reduction in their germination was observed during sulfate-chloride salinization. The predominance of sulfates in the salt composition up to 0.4% did not have a negative effect on seed germination, while the predominance of chlorides reduced their germination, starting from 0.2%. If the difference between the two types of salinization at 0.4% was only 2%, then at 1.4% it reached 18%, which indicates an increase in the toxic effects of chlorides as their concentrations increase. In the process of growing plants, soil salts affect plants directly through the root system.

Published: May 2020

Residual brewing yeast is one of the main solid wastes in brewing. Using residual brewing biomass as a source of biologically active substances is an important way of recycling these brewing by-products. According to the literature S. cerevisiae is considered as the promising source of polysaccharides, particularly beta-glucans. Beta-glucans are structural polysaccharides of the yeast cell and perform immune stimulating properties. At the same time, there is too little information about the content of these polysaccharides in brewing yeast of the genus Brettanomyces. The objects of this study were yeast cultures of Saccharomyces cerevisiae and Brettanomyces bruxellensis. In this work, the cultivations of the yeasts were carried out to compare them as possible sources of beta-glucans. The yeasts were cultivated in a simple periodic culture using a laboratory fermenter (Biostat A, Sartorius). As a result, the content of beta-glucans in the yeasts S. cerevisiae and B. bruxellensis biomass was measured by enzymatic method (Megazyme, Ireland). According to the obtained data, the yeast B. bruxellensis contains a higher amount of beta-glucans than the yeast S. cerevisiae.
Digital cartographic support of geodynamic safety of subsoil use based on UAV technologies
Authors: Solovitskiy Aleksandr
Published: May 2020

It is established that the problem of digital cartographic support for geodynamic safety based on UAV technologies is the following: on the one hand, a significant increase in accuracy and efficiency of survey work and on the other hand – the lack of new models for approximating the crustal blocks, taking into account the adequacy of their configuration, hierarchy, structure, interaction and geodynamic activity. Traditional technologies are focused on the use of flat models of crustal blocks, which are not adequate and give ambiguous state parameters. The aim of the research is to develop a theory of digital cartographic support for the geodynamic safety of subsurface use, which provides not only the creation of new models of blocks of the earth’s crust based on their selection and identification, taking into account the accuracy of cartographic materials, but also provides an information basis for gaining new knowledge about their stress-strain state according to the structure hierarchy which is necessary to solve this problem. Based on the performed research, it was found that the morphostructural analysis of the cartographic materials of the territory in the area of the mining enterprise, obtained on the basis of UAV technologies, is more informative and automated, covers the latest period up to one million years and takes into account the dependence of their errors on the duration and relaxation of geodynamic processes . The practical use of this theory is safe subsoil use.
Prediction of deformations in the subsiding soils of Eastern Donbass’ undermined areas
Authors: Prokopov Al’bert , Shuiskii Anatolii , Shcherban’ Evgenii , Zhur Vyacheslav
Published: May 2020

Subsiding soils are structurally unstable and are common and Russia (Northern Caucasus, Western Siberia, etc.) as well as worldwide (China, Mongolia, Central Asia, North America, etc.). Construction and operation of buildings and structures on such soils are associated with the nonuniform subsiding of soil due to water saturation, which causes excessive deformations in basements and foundations. The geotechnical and technogenic conditions of Eastern Donbass feature the commonness of subsiding loess soils and undermining of industrial areas prone to waterlogging. The three mentioned factors have a negative impact on ground facilities due to nonuniform vertical and horizontal deformations of the Earth’s surface. Despite considerable scientific progress in studying the surficial deformations attributable to various factors, the concurrent effects of undermining, technogenic waterlogging, and manifestation of subsiding properties on the condition of buildings and structures are currently understudied. This paper proposes a method for predicting the deformation of subsiding massifs in the undermined areas of Eastern Donbass. The research team has developed an analytical method for assessing the damage to a typical urban structure simultaneously exposed to soil subsidence and undermining.

Monitoring of agrophysical properties of the active layer of drained long-frozen peat deposits in Western Siberia
Authors: Novokhatin Vasily , Osipova Nadezhda
Published: May 2020

In this study, the authors considered the dynamics of the main agrophysical properties of hydromorphic geosystems in Western Siberia. In the process of evolution, as well as in the conditions of technogenic impact, the soils of natural-territorial complexes, their properties are subject to significant changes. New hydromorphic geosystems are formed, the soils of which are characterized by changed agrophysical properties. Modern technologies for developing investment projects for soil reclamation of hydromorphic geosystems should be based on agrophysical characteristics of reclaimed soils, on the basis of which it is possible to create the necessary parameters of drainage systems and, as a result, provide optimal soil regimes for agricultural crops for a long period. The difficulty is that these soil characteristics are variable over time. Until recently, agrophysical characteristics of soils obtained in other regions of the country were used in the development of reclamation projects for hydromorphic soils in Western Siberia. The attempt to borrow them has led to the fact that large areas of drained soil have become completely unsuitable and to restore their project productivity, a number of agro-reclamation activities and the attraction of large financial resources are currently required. In this regard, there is a need for a comprehensive, long-term study of the main properties of hydromorphic soils used for agricultural purposes, and especially their changes over time under the influence of anthropogenic load.
Comparison of different land distribution mechanisms for a land-hungry region
Authors: Gurtuev Alim , Ivanov Zaur
Published: May 2020

This paper proposes an approach to the development an efficient land distribution mechanism for a particular land-hungry region. We separate budgetary and allocative efficiency and use general utility approach during evaluation of particular distribution mechanisms. We propose a model of potential land users, which allows quantifying the efficiency of a number of mechanisms of land distribution for land-hungry regions. Land users are represented as economic agents with bounded rationality and subjective utility functions. The model calculates allocation efficiency and budgetary efficiency as independent values and thus is more precise. It also has considerable flexibility and can be adjusted to specific agricultural technology and soil types. An analysis of the efficiency of various mechanisms for the test region showed that lottery mechanisms leads to losses of allocative efficiency compared with auction mechanisms. As for the budget revenues, the use of lottery mechanisms leads to much smaller losses of budgetary efficiency in comparison with simultaneous closed auctions of the first and second prices. But of all the mechanisms considered in the paper, the repetitive Vickrey auction leads to the smallest losses of budget efficiency in the model.

Authors: Ivanov Zaur , Gurtuev Alim , Israilov Magamed
Published: May 2020

The purpose of the study is to improve the method of economic assessment of limited land resources in the mountainous territories of the North Caucasus Federal district. The article analyzes specific shortcomings of the methodology currently used in Russia, which does not have a sufficiently objective scientific basis. Our approach is based on the synthesis of modern achievements of agro-economic science. Attempts to systematize the economic assessment of land in the agricultural sector of the Russian Federation depending on the land quality did not lead to positive results. This is first aspect of the problem we are studying. The second aspect is that the problem is not developed from the economic point of view. A positive differential rent is automatically included in the market value of agricultural products. The third aspect is the formation of tax and rental rates for agricultural land in direct correlation with the cadastral value. As a result, there is a research problem of objective assessment of limited agricultural land in agriculture. The method of economic evaluation of agricultural lands of the state Committee for land use of the Russian Federation has been improved.

Published: May 2020

According to numerous studies, even with a relatively low level of exposure to adverse environmental factors, risk of health deterioration may occur. Both the amount of harmful emissions and their chemical composition directly affect the level of air pollution. The article considers the issues of environmental pollution of an urbanized area by automobile exhausts. The most polluted city is Vladikavkaz that is the capital of the Republic. There the main stationary sources of pollution are located and the largest number of vehicles is concentrated. The dynamics of increasing the number of vehicles in the city of Vladikavkaz over the past 10 years and a corresponding increase in harmful emissions from combustion products are shown. For the same period of time, the amount of emissions of harmful substances into the atmosphere from stationary sources has been considered in order to compare their contribution to total pollution compared to road transport. Based on the explorations, it is shown that the main source of pollution in terms of emissions in the Republic of North Ossetia-Alania is road transport. The number of vehicles is increasing year after year, amid a decrease in total emissions of pollutants from stationary sources.

Published: May 2020

The aggravation of the environmental situation in major cities of the Russian Federation has been observed in recent years. A significant contribution to the deterioration of the quality of the urban environment has a large number of vehicles and consequently the number of gas stations. They are generally concentrated within the city limits. As a result of the high level of competition of oil companies in the gas station market and the large consumption of liquid fuel oil by the urban population there is a point building of gas stations on free sites of urban development. The question of the need to improve the ecological safety of urban gas filling stations is acute and remains extremely relevant in our time. On the basis of the results of theoretical, numerical and experimental studies obtained by the authors, factors influencing spread of harmful substances from emission sources at gas stations have been identified, and their significance was established. The identified factors formed the basis of a multi-criteria analysis of the environmental impact of emissions from sources at gas filling stations. The authors have developed a methodology for assessing environmental safety of urban gas filling stations, which allows to assess the degree of impact of gas filling stations on the urban environment and to reduce their negative effect.

Measuring systems using the design of laser module beams on the surface of the object under study are considered. A technique is proposed for experimental researches of the brightness structure of the study of laser modules. Adaptive algorithms on the type of module and distance have been developed for determining the coordinates of light marks on the surface of controlled products. The need for high-precision measuring systems to carry out their pre-liminary selection and calibration of laser modules according to the proposed method, taking into account the range of design of light marks, is shown. It is shown in the work that the accu-racy of determining the relative coordinates in the trajectory of the light marks of laser mod-ules for monochromatic targets can be several times higher (0.2 - 0.3 mm) than the accuracy of determining their absolute coordinates (≈ 1 mm).

Published: May 2020

The analysis and consideration of the influence of the main factors on the damage of welded metal structures during long-term operation. The relationship between the strength of the magnetic field of the Hр scattering and structural changes in structural steels that occur during cold plastic deformation to different degrees is established. It is shown that at small degrees of deformation, the change in the magnetic parameter Hр is large. As they increase, the HP value decreases and tends to the values of the Earth's magnetic field. The data of microstructural analysis of the metal of structural steels are in good agreement with the results of the passive ferrosonde method of control. A method for evaluating the effect of cold plastic deformation on the magnetic properties of metal in structural steels has been developed.

Published: May 2020

The study is intended for engineers designing hybrid systems. The analytic hierarchy method was used as the main tool of foresight. Nowadays, some experience in the design of optoelectronic systems is accumulated. However, in most cases, designers have to sort through all possible factors and parameters of devices. The involvement of experts for questionnaire survey will reduce the time range of designing. The results of the study show a high consistency of experts' opinions with the Kendall coefficient value of 0.782. Research materials in the future will allow planning experiments only with the most important factors. This will adjust the protocols for testing new optoelectronic systems and significantly reduce costs.

Published: May 2020

The study on issues of digital economy proved the current existence of the new “digital” economic reality. The traditional legal apparatus used for the statutory regulation of this new economic reality showed itself not only inefficient, but also significantly restraining the actively developing economic processes. In this regard, a plenty of practical and legal collisions occur related to the problems of identification of persons involved in civil-law transactions, property relations regarding digital economic turnover (for instance, relations concerning property rights in the field of distributed ledgers), registration of property rights and deals, regulation of banking line processes, formation of special protection models for relationships based on the use of digital technologies including issues of cybernetic and data security. The development of digital economy will inevitably influence legal principles and demand reconsidering some of doctrinal approaches to traditional legal models of regulating different types of economic activities. In this case, socially just changes in the legal regulation of economic activities should be primarily aimed at removing legal barriers that impede the development of digital economy, as well as at synchronizing legal rules with the technological features of economy’s functioning.

Authors: Filimonova Irina , Komarova Anna , Chebotareva Anastasia
Published: May 2020

The article presents an analysis of performance indicators of companies in the oil and gas industry of Russia in 2013-2018. The aim of the study is to decompose the factors of change in the return on equity (ROE) of Russian oil and gas companies. The authors used the Dupont method to identify the main factors affecting ROE. After decomposing the ROE into factors, the authors evaluated their impact using the Logarithmic Mean Divisia Index (LMDI-1). As a result of the study, it was found that in most companies the greatest impact on the change in ROE has a return on sales, primarily as a result of revenue growth due to favorable oil prices and positive exchange rate differences. Simultaneously, sales profitability has a positive effect on the index of almost all companies in the industry. Asset turnover also had only a positive effect on ROE. However, a comparison of the results for 2017 and 2018 showed a significant difference in performance for many companies. Thus, we can conclude that the effect of a certain factor on the profitability of sales largely depends on the development strategy of the company for the coming year, the economic and political situation.
Digital marketing in the SPA-resort product promoting

Published: May 2020

Digital marketing technologies create new ways for driving customers in spa-product purchasing, providing feedbacks and endorsements due to new methods of communication, supporting and reinforcing Spa-resort product producers and distributors promises. Actually, at this time resort market has no effective and united strategy for SPA-resort product promotion and sales, which has to be based on modern digital marketing instruments. The review of digital SPA-resort market in Black Sea resorts and Caucasian Spas areas revealed the lack of coordination between providers of natural curative resources, tourist’s accommodation means, healthcare facilities and travel organizers. Ignoring the specifics of SPA-resort product and uniqueness of its nature in its promotion and merchandising causes the drop-in sales because of the decrease in consumer interest and lack of information about variety of product benefits for health resumption. Thus, recommendations and suggestions about possible ways of joining efforts in SPA-product rout-to market with use of digital marketing technologies would show a large return to the resort industry in a long-term period.

The main task of the project manager is risk management. However, this task can be very complicated and inefficient if risk management is not considered from the beginning of the project. An effective risk management approach requires a systematic and appropriate approach, knowledge and experience. Studies of many projects have shown that both the owner and the contractor do not regularly implement risk management practices, which can have negative consequences on project performance. Because of the above-mentioned issues in this study, it is attempted to first evaluate the concepts of project risk management based on different and valid standards, to evaluate risk management in construction projects. Then, an attempt has been made to present an implementation approach for implementing six stages of risk management in projects. For this purpose, based on the experiences of the project “Lala Residential Complex” in Kabul, as a case study, the experimental application of the proposed method in this study, step by step, along with forms designed for follow-up and Implementation of process steps have been evaluated and evaluated in accordance with the PMBOK standard by the Project Management Institute (PMI) to ensure that it is moving toward achieving project economic risk management goals.
