Authors: Ivanova I S , Korol I S , Korneev D S 
Published: April 2020

Abstract
Organic matter is an integral part of the chemical composition of natural waters and plays an important role in collection and migration of chemical elements, including pollutants in water bodies. The article presents the chemical and organic composition of layer waters in the Sovetskoe and Vakhskoe oil deposits in the Tomsk region. Underground waters have chloride and sodium, and a high concentration of organic matter (sorg up to 90 mg/l). The goal of the publication is to identify the main patterns in the distribution of diluted organic matter by groups in layer waters in the south of Western Siberia and determine their potential contribution to the migration and collection of micro-elements. On the basis of the collected data on the group composition of diluted organic matter, it has been established that alkanes, naphthalens, alkyl benzenes, cyclohexanes, phenanthrenes are the most common. The results of the analysis of the micro-element composition of the extracted organic matter from the underground waters show that there is no correlation between the micro-elements composition of the water organic matter and various groups of compounds in it. We have a made suggestion that the key role in the migration and accumulation of micro-elements in water belongs to high-molecular components of organic matter that is characterised by its diverse composition and complex insufficiently studied structure.

Authors: Nim Y A , Gogoleva L P , Illarionova M G 
Published: April 2020

Abstract
To expand the scope of unsteady electromagnetic fields in marine and land prospecting and mapping studies of deep-seated and/or polarized geological objects, such as oil and gas deposits, kimberlite bodies and other minerals, it is advisable to consider an engineering-analytical multicomponent model of an electrically conductive layer when excited by horizontal electric dipole – the classic causative agent of the formation of the field of horizontally layered media. To simplify analytical studies, the Cole-Cole dispersion model adopted for the polarized known plane Sη
was adopted as polarizable electrically conductive layer. The components of analytical expressions are described that describe the establishment of the electromagnetic field of an induction-induced polarizing conductive layer — objects of hydrocarbon deposits and sulphide ore occurrences. To identify the deep horizontal inhomogeneities of the section, equations are given that describe multicomponent fluxes of magnetic induction of polarized formation.
Biological and Chromatic Characteristics of Plants as a Factor for Monitoring and Management of Production Process When Applying Fertilizing Features of Production Wastes
Authors: Stepanova L P , Korenkova E A , Myshkin A I 
Published: April 2020

Abstract
The localization and intensity of technogenic flows of chemical elements causes the formation of technogenic anomalies and biogeochemical provinces with varying degrees of environmental distress. The purpose of the research is environmental assessment of the effectiveness of the fertilizing properties of metallurgical production wastes in nutrient soils. Studies have been conducted to determine the degree of influence of the fertilizing effect of various types of nutrient soils based on soil, slag and zeolite on germination, growth and development of seedlings of small-seeded lettuce. Seed germination, plant growth and development are affected by the water-physical properties of soils and the number of available macro and trace elements. Visual and computerized assessment of the color range of the lettuce leaves is proven to be effective to assess the level of soil contamination based on the intensity of nutrient consumption by plants.

The Necessity of Using Developed Cultural Traditions in Contemporary Architecture of South of Russia
Authors: Solodilova L A 
Published: April 2020

Abstract
Nowadays travelers all over the world are eager to see local traditional architecture typical for the given area. But the globalization processes that penetrated into architectural sphere as well, have turned the historical centers of many towns and cities into twins in their spatial pattern, technologies and materials used. As a rule, these are buildings made of glass and concrete, so characteristic for rational contemporary solutions. At the same time, there is historical architecture, surprisingly surviving in quiet outskirts of southern Russian cities and attracting genuine interest. Using photometry methods, the authors have detected, analyzed and graphically processed these examples. This architecture retained facade patterns representing artistic work of different people inhabiting the region. Each of these nations brought their own national traditions in the way of life and ornamental decoration of houses in specific form and pattern. It gives room for imagination of modern architects.

Abstract
Russia’s public interest is focused on modernization problems. To make Russia’s towns and cities look up-to-date must be the main task of this process. Actual art can become an effective way to aestheticism the urban area. The objective of the given article is to define and specify mechanisms of new cultural actions aimed at a creation of a new experimental phenomenon – an urban area as an integral exhibit space. At present, there are a great many methods for changing the situation in the cultural context of modern towns and cities. Nowadays, actual forms of art can become a most efficient tool of social co-operation. Informational, didactic, aesthetic, and ideological functions of art implemented in large-scale town art projects and art objects can significantly influence town residents’ way of thinking, help to unite the local community, form new kinds of leisure activities, and encourage creative activities of people of all ages. Involving young designer teams, student architectural studios, and decorative artist alliances can be regarded as a method for solving the above mentioned problems. In this case, the major idea is to make joint team efforts in order to create innovation residential areas. The results can be expressed in design concepts directed towards integrating contemporary art into the context of the urban environment. This article is meant to be a basis of the content that will allow to get quickly acquainted with actual concepts and methods for solving problems of forming cultural “landscape” and contemporary urban area ambience. Provided, active involving creative youth in co-operation process for both, creation of art objects and discussion of them, is to be a necessary condition. Cognitive methods for mastering actual art techniques, new visualization forms, and gaming and carnival scripts of art projects presentations are intended to become an efficient mechanism for creating a basically new appearance of towns and cities.

Published: April 2020

Abstract
Harbin - modern metropolis of northern China. Developing at an intense pace, he catastrophically lost his architectural heritage. To liberate territories for new construction, historical objects with unique architecture that were designed by Russian specialists were demolished. Currently, the historical environment of the city has been preserved in fragments. But in the architecture of new buildings there is a steady tendency to use retro styles as: baroque, classicism, modern, gothic.
Lost Architecture of the East frontier
Authors: Ivanova A P 
Published: April 2020

Abstract
This article talks about lost or destroyed objects that were built at early stages of colonization of the eastern frontier of the Russian Empire. The classification proposed by the author will include three categories: temporary wooden architecture with elements of a “national style” that decorated public spaces (arches, verandas, awnings, landing stages, carved facade decorations of educational institutions, railway stations, etc.); residential buildings of Russian and Ukrainian settlers; dachas, trading posts, estates and castles created by foreign and westernized Russian entrepreneurs (Yankovsky, Startsev, F. Geck, etc). The conclusion says that it is important to reproduce not only individual objects, but the lifestyle of the first colonists who reproduced European civilization patterns “in the wilds of the Ussuri Krai”. The empirical base of the study consists of materials of the expeditions, historical photographs and memoirs.

Topical Issues of Staffing in the Hospitality Industry of the Republic of Crimea
Authors: Zhavoronkova O R , Nikiforov I R 
Published: April 2020

Abstract
The paper deals with the current state of staffing the hospitality industry enterprises with qualified personnel. The dynamics of staff flows, as well as their remuneration rate are described. In addition, the paper highlights main activities undertaken by the Ministry of Tourism and Resorts of the Republic of Crimea and the Ministry of Education, Science and Youth of the Republic of Crimea connected with personnel availability in collective accommodation facilities. It is proved that these measures solve the issue of staffing during the holiday season partially. At the same time, the existing policy does not contribute to the human resource capacity building and development, as it leaves unsettled challenges associated with employee turnover and their full employment. The relevant factors with a negative influence on the staffing in the hospitality industry enterprises are considered. Certain activities carried out to neutralize the negative impact of these factors are described. Some possible solutions for the problem under consideration are proposed. It is stated that solving staffing issues must be addressed comprehensively with resolution of common challenges in the hospitality industry. Considering an uneven distribution of resources in the Republic of Crimea, including collective accommodation facilities, the paper explains practicability of creating a tourism cluster in the region. To cope with challenges noted in the paper, a concentric diversification scenario of creating a tourism cluster is proposed. Some dominant factors of creating the tourism cluster, such as establishing boundaries of the state’s partnership with representatives of the business environment and other institutions in education, health, catering, leisure and other related areas, are noted. When establishing partnerships between the government and potential participants in the cluster, it is necessary for the government to provide support for defining the collaborative mechanism, beneficiaries and each cluster member’s responsibilities.
Contemporary Urban Space: Social Reflection
Authors: Kostina E , Orlova N , Panfilova A 
Published: April 2020

Abstract
The article deals with the social nature of the city, modern urban processes and their impact on human life. The continuous growth of the urban population is a trend of the last century and at the same time a sociocultural challenge that changes the parameters of human life. Indeed, for a comfortable living in the city it is not enough to take into account the requirements of the engineering and technical networks of the architectural space, it is necessary to take into account other aspects of human interaction with the urban environment. This is important for the further social development of the urban lands, for the formation and promotion of a benevolent attitude of the residents to their city, and a sincere desire to improve its environment. These tasks are also priority guidelines for the public policy. The marginalization of urban space in a number of its forms opposes these tasks; on the contrary, it forms a marginal urban identity among the residents, manifested in the absence of attachment to the city, indifferent and irresponsible, and sometimes criminal attitude to it and its objects. The way out that the authors see is expanding social cooperation, involving townspeople in the development of the urban environment, stimulating public initiative in this area; strengthening the interaction of the public urban circles with managers; in establishing a dialogue between them.
Research of Oily Wastewater Treatment by means of Membrane Methods
Authors: Makisha N 
Published: April 2020

Abstract
Membrane bioreactors nowadays are intensively applied in wastewater treatment worldwide. Such type of treatment systems has a large scope of implementation at facilities of different capacity. Undoubtedly, the use of MBR for the treatment of industrial wastewater greatly simplifies the process with significant fluctuations in the concentrations in the original wastewater and the presence of “volley discharges”. BMR technology-bio-reactor with activated carbon and membrane separation is also of a certain interest. The use of this technology largely solves the issue of post-treatment of refinery wastewater, but returns us to the problem of high operating costs. An alternative to biological methods of wastewater treatment of the refinery can be the use of reverse osmosis plants for this purpose, providing the necessary degree of purification for a number of indicators. The method of reverse osmosis (RO) is already widely used in schemes of water treatment, drinking water supply and post-treatment of wastewater for reuse.
Scour Characteristics of the Underwater Crossing of Trunk Gas Pipeline Across the River Lena
Authors: Ammosov G S , Kornilova Z G , Yakovlev Yu A 
Published: April 2020

Abstract
The design data of the underwater crossing of the trunk gas pipeline (TGPL), which is an extension of the main gas pipeline of Hatassy GDS-2, for gasification of regions on the eastern side of the river Lena of the Republic of Sakha (Yakutia) are considered. Scours behaviour of the underwater crossing of TGPL across the river Lena is examined taking into account hydromorphological factors. The influence of hydrological and exogenous processes on the state of the underwater passage of Hatassy-Pavlovsk TGPL is shown by the example of the line-II. Changes of the river bottom profiles in the area of TGPL fixed at four discharge section lines, as well as water consumption were analyzed. It is shown that the presence of the underwater gas pipeline significantly affects the nature of the movement of micro- and meso-forms of the river bottom. It has been established that the constantly changing hydrological and hydromorphological processes resulted in sagging of the inverted siphon section in the line-II of the underwater crossing of Hatassy-Pavlovsk TGPL. During the designing and construction of the first line of the underwater gas pipeline across the river Lena, major omissions were committed, the peculiarities of the hydromorphological and hydrologic features of the river bed evolution in the section of the underwater passage of Tabaga-Kangalassy TGPL across the river Lena had not been taken into account. The effects of hydrodynamic and permafrost processes, heaving phenomena on floodplain and shore slope together increase the non-functional loads on the underwater gas pipeline. As a result of these factors, high longitudinal tensile stresses arise, especially in the welded joints of the inverted siphon pipes, and lead to accidents and incidents at the underwater gas pipeline across the river Lena.
Experimental Study of Shear Behavior of Rock Joints under Two Types of Boundary Conditions: Constant Normal Load and Constant Normal Stiffness
Authors: Usol’tseva O M , Tsoi P A , Semenov V N 
Published: April 2020

Abstract
Shear destruction of rock mass along weakened planes is one of the main reasons of the failure of career boards, underground workings and rock slopes. The paper deals with laboratory testing of rock joints under direct shear loading. Special test and measurement complex was created to study deformation and strength characteristics of rock joints. Test specimens were made from single slab of sandstone of homogeneous structure. Shear tests have been conducted under constant normal load (CNL) and constant normal stiffness (CNS) boundary conditions at three values of normal compressive stress: 0.5 MPa, 1.2 MPa and 1.8 MPa. The analysis of test results allowed to reveal patterns of changes of deformation-strength properties of rock joints depending on the level of normal load, boundary conditions and roughness values. The ultimate shear stress is always higher under CNS boundary condition than CNL for the same values of normal compressive stress. Shear stress practically retains constant value after reaching the ultimate stress under CNL boundary conditions and it decreases under CNS conditions. The values of ultimate shear stresses, shear modulus and the length of linear section on “shear stress–shear displacement” curve increases with increasing surface roughness at the equal levels of normal compressive stress.

The Swimming Behavior of Daphnia Magna Ensemble in Two-Dimensional Space from the Diffusion Motion Point of View
Authors: Nasyrova E I , Nikitin O V 
Published: April 2020

Abstract
Locomotion and dispersal are important processes that affect the distribution and abundance of organisms in aquatic environment. In this study we observed the movement of a group of Daphnia magna called an ensemble. In laboratory conditions, the distribution of fifty daphnids (in triplicate) at the release from the point source in two-dimensions was examined. In experiments, animals were placed in a square plastic container with thin layer of culture medium and the video of their movements was recorded. Video processing and measuring of swimming behaviour was carried out by the TrackTox software. Mathematical and statistical analyses were performed using the functions and packages of the R software. The diffusion motion equation used allowed to obtain the value of the diffusion coefficient, which in our case was 0.051±0.009 cm2 s–1. The approach used can be used to model the migration and spatial distribution of these microscopic crustaceans. Moreover, given the fact that certain parameters of swimming behavior are already used to toxicity assessment, the diffusion parameters of a Daphnia ensemble can also be proposed as a characteristic in ecotoxicological studies.
