“Cities are Good for Us”: Assessment of Urban Attractiveness by Students
Authors: Antonova N , Abramova S , Polyakova V 
Published: April 2020

Abstract
The article reveals the foundation of attractiveness of the city as a place of residence, as a place of realization of needs of student youth. The city, as a high-resource territory, becomes a factor in the formation of migration attitudes of the young generation, which acts as a driver for its successful functioning and development. Cities engage in global competition for human resources. The lack of competitive advantages (such as a favourable environment, high level of income, quality of life, developed infrastructure) is becoming a factor of outflow of youth to more attractive areas. In 2017, we conducted a sociological study of students of the city of Yekaterinburg (Russia). Based on a standardized survey of 200 students (71 men and 129 women), as well as on 8 in-depth interviews with 4 women and 4 men, the article argues that the factors of the city’s attractiveness are the conditions contributing to the upward vertical mobility. The most attractive characteristic of the urban environment is the economic, environmental and socio-cultural sustainability, which creates the conditions for the successful implementation of life plans, initiative and innovation. When choosing a city for the realization of their interests, students consider the territory’s ability to provide opportunities for informal interaction and free choice of everyday practices. These indicators of attractiveness demonstrate that students claim their right to the city: they change themselves by changing the city.

Published: April 2020

Abstract
The current state of modeling regional socio-economic systems cannot yet be defined as an effective tool for developing regional policy in the Russian Federation. The article presents an algorithm for modeling a regional socio-economic system for the needs of the developed information advising system. The authors have carried out an algorithm that substantiates the expediency of applying a specific mathematical function to describe trends in increasing indicators for forecasting the socio-economic development of the Russian Federation region in the devised information advising system. The article presents the experience of using multiple regression to simulate the values of the sample indicator of developing the regional socio-economic system “Investments in fixed capital” on the example of the Bryansk region. As the initial data, the departmental expenditure structure of the Bryansk region is used for the departments of economic growth, construction and architecture for 2011-2019. The regression equations are formed, and then the model is evaluated for reliability, and the results of the regression analysis for the estimated indicator are given. The article makes the conclusion that using multifactorial correlation and regression analysis to simulate a regional socio-economic system on the data of the Bryansk region will expand the capabilities of the developed information advising system.

Authors: Grudinsky P I , Podjelnikova E S , Dyubanov V G 
Published: April 2020

Abstract
The paper presents a study of sulphatizing roasting using iron (II) and (III) sulphates of copper slag flotation tailings of JSC “SUMZ” (Sredneuralsk Copper Smelter) with high content of silica. Temperature ranges of sulphatizing roasting and necessary amounts of Fe2(SO4)3 and FeSO4 for sulphation of zinc and copper were calculated by thermodynamic software HSC Chemistry 9.9. The laboratory experiments have shown that the degree of extraction of zinc and copper from the roasted samples during water leaching is in the range of 60-79%, while the degree of dissolution of iron is less than 1.1%. The obtained results are better or comparable to the results of direct leaching of copper tailings by strong sulfuric acid.
Development of Damage Evaluation Methods in Uneasily Accessible Units of Oil and Gas Equipment
Authors: Pivovarov V Yu , Duvakina I I 
Published: April 2020

Abstract
The article represents the issue of the possible identification of uneasily accessible assemblies of oil and gas equipment. Sensitivity of the system as a whole to changes occurring in its individual sections was hypothesized and tested. The work was based on the study of the output voltage of the electromagnetic signal with the eddy current control method. A special feature of the experiment was the use of a standard sample for low-cycle fatigue, but with an elongated end, a “tail,” that does not experience deformations. Measurements of the output voltage were carried out with a certain periodicity at four different frequencies of alternating current: 15, 30, 60 and 100 Hz. Analysis of the results showed that the “tail” part of the sample responds to the accumulation of damage in its working area, which made it possible to talk about the possibility of development of a method for remote diagnostics of equipment and structures.

Authors: Biragova N F , Tinikashvili N A , Dmitrieva T V 
Published: April 2020

Abstract
Rapid industrialization and urban growth coupled with continual improvement of urban spaces requires addressing the challenges of preventing negative anthropogenic impact on the environment.
In particular, this applies to food processing, a strategic sector that sustainably provides people with high-quality food. Food processing affects water reservoirs the most. Closed cycles are the solution proposed to prevent or reduce the environmental impact of food processing wastes. This will help not only address environmental issues but also optimize the use of natural resources.
Wastewaters contain fodder residues, table salt, detergents, nitrites, phosphates, alkali, acids; they might also contain pathogenic microflora.
This paper presents an optimal technology for the neutralization and deep treatment of AIC wastewaters.
Geochemistry of Water-Dissolved Gases of Oil-and-Gas Bearing Deposits in Northern and Arctic Regions of Western Siberia
Authors: Dultsev F F , Chernykh A V 
Published: April 2020

Abstract
The paper presents a pioneering attempt in the last 35 years, to summarize the accumulated data on geochemistry of water-dissolved gases of oil and gas-bearing deposits in northern and arctic regions of Western Siberia. Water- dissolved gases from all the studied oil/gas fields are characterized by absolute predominance (up to 75-99 vol.%) of the methane series hydrocarbons in their composition. The identified (after the L.M. Zorkin’s classification) four classes of hydrocarbon type of water-dissolved gases (vol.%) are designated as: dry (ΣHH < 1), lean (ΣHH = 1-3), semi-fat (ΣHH = 3-5) and fat (ΣHH> 5). The total gas saturation of groundwaters ranges from 0.3 to 5.7 L/L with CH4 concentrations averaging 95.5 vol.% in the Aptian-Albian-Cenomanian to 83.3 vol.% in the Lower-Middle Jurassic complexes. The levels of homologues ΣHH (C2H6, C3H8, C4H10, C5H12 and C6H14) tend to increase with depth: from 1.34 vol.% in the Aptian-Albian-Cenomanian to 11.67 vol.% in the Lower-Middle Jurassic complex. The maximum ΣHH concentrations reaching 30 vol.% were found at the Neocomian base in the peripheral waters of oil accumulations. CO2 levels show an increasing trend with depth, whereas N2 concentrations tend to decrease. Given the increased depths and more severe temperature conditions, the level of hydrocarbon generation remains high, however hydrocarbon series is characterized by a shift towards liquid components and methane homologues (the main zone of oil/fat gases generation). Therefore, the revealed in the Lower-Middle Jurassic complex highly gas-saturated groundwaters (up to 4.5-5.7 L/L) enriched with methane homologues allow to assess their hydrocarbon prospects as very high.
The Impact of the Medium-Wave UV Radiation on the State of Embryonic Membrane of Amphibian
Authors: Habaeva Z G , Gagloeva M T , Gappoeva V S 
Published: April 2020

Abstract
The relation between the destruction of tertiary egg membrane of an amphibian embryo irradiated during the neurula stage and the dose of radiation was revealed. In order to determine the degree of membrane destruction methylene blue was used which made it possible to evaluate its structural and functional integrity level depending on the dye penetration rate. The longer the exposure time was, the more considerable the destruction of tertiary egg membrane turned out to be: it was gradually losing its shape, structure, and was getting more permeable to dye. These changes provoked the release of the amphibian embryos that started to lose their suspension properties and fell on a Petri plate, yet some of them being of a great vitality.

Authors: Nevedrov N , Protsenko E , Poluyanov A 
Published: April 2020

Abstract
The article focuses on the features of the morphological, physical and chemical properties of the humus-accumulative embryo soils of nonfunctional stock heap of Mikhailovsky Mining and Concentrating Company (Mikhailovsky MCC). The biological activity of various groups of soil microorganisms: actinomycetes, microfungus and ammonifying saprophytes was studied. The types of plant communities of technogenic territory of overburden stock heap are identified, the main parameters describing the structure and dynamics of phytocenosis are described. It is established that the soils of key catena have high numbers of fungic microflora up to 145 thousand CFU / g in the gray-humus horizon, actinomycetes and ammonifiers have a low level of development. However, as relating to the previously obtained data, a general temporal tendency has been revealed, characterized by the increase in the biological activity and biomass of the groups under consideration, which is clearly observed in areas with soils rich in organic matter and mineral elements.
The Role of Small and Medium-Sized Businesses in the Development of Oil and Gas Fields on the Arctic Shelf of the Russian Federation
Authors: Fadeev A M , Tsukerman V A 
Published: April 2020

Abstract
The article discusses the range of issues of economic interaction between operators of projects on the development of the Arctic shelf and companies supplying products and services for the needs of the oil and gas complex. The authors analyzed the economic multiplier effect arising from the involvement of small and medium-sized enterprises in the implementation of oil and gas projects.
A common opinion is that only large corporations can do such work. Without denying the validity of the judgment on the possibility of implementing oil and gas projects in the Arctic only by experienced companies that have sufficient competence for the safe and efficient performance of work, it is worth noting that the modern structure of the global oil and gas complex (NGC) is largely represented by small and medium-sized enterprises. In 7 out of 10 such companies, the personnel does not exceed 10 people. Very important and indicative is the fact that during the implementation of large-scale projects for the development of hydrocarbon deposits, the share of suppliers of the oil and gas complex accounts for up to 80%.
Protected Area Biodiversity Conservation: Population Dynamics
Authors: Vasilyev M D , Vasilyeva N V , Trofimtsev Yu I 
Published: April 2020

Abstract
One of the methods for protecting the environment and conserving species biodiversity is the creation of protected areas, the task of which is to conserve rare species of animals and plants. The dynamics of populations can be studied quite effectively with the mathematical models. Modeling allows to study all possible scenarios of interaction and development of populations, to evaluate the influence of the environment on the spatial-temporal dynamics of biological communities. The paper considers a non-linear model of a protected population, the feature of which is the presence of a bilocal range and the exchange of species between its parts. It is a system of nonlinear parabolic partial differential equations that describes the dependence of migration flows on the uneven distribution of species in an area with a generalized resource. A complex of programs was coded in Python programming language for numerical study of diffusion models and visualization of the results obtained. Numerical simulation results of cross-diffusion effects and influence of generalized resource are analyzed in detail. The obtained results of research can be used for studying the processes in the protected population, for assessing the size of the protected areas being created, determining the conditions of population degeneration and recommendations for their stable existence.
Risk Factors for Construction and Exploitation of the Industrial Facilities on the Arctic Shelves: Actual Challenges and Perspective Approaches for Adequate Decisions
Authors: Vinogradov A N , Tsukerman V A 
Published: April 2020

Abstract
The bottom sedimental cover on Arctic shelves includes a layer of subaqual permafrost. There are two types of soil grounds within this layer: the conventional 4-phase frozen soils MWIG (“mineral matrix – water – ice – gas”), and the binary type SSGH (“Frozen Soil Saturated by Methane Gas-Hydrates”), which present in fact a mix of MWIG and significant portion of the alternative clathrate subsystem, presented by hydrocarbon gases in icy nano-scaled cells. The SSGH type locates within the gas-hydrate stability zone (HSZ), its upper limit is not constant in a time and may change a depth from 0 meters at the cold glacial epochs up to some hundred meters deeper a surface of sea bottom during the warm interglacial periods. Into the Holocene warm stadia the HSZ depth on the Arctic shelves vary of 50 to 200 meters, but some relics of SSGH soils occur in metastable conditions over the upper limit. Moreover, the lenses of SSGH may to appear near surface in a result of transformation MWIG soil in a stress field under huge gravitational platforms installed on shallow shelf. Geomechanical features of SSGH drastically differ of MWIG, and so for industrial safety it is necessary to provide an advanced and permanent geophysical control of the SSGH abundance and stability under a basement of engineering facilities. The most attractive and reliable approach to those goals is installation around the large industrial objects a fiber optic sensing network, consisting of seismoacoustic and electromagnetic recorders integrated in the single “phase antenna” with digital “big data” processing.

Published: April 2020

Abstract
The multiannual geological, geomechanical and astrophysical studies have proved the periodic expansion and compression of our Galaxy’s stars, the Sun and the Earth. This phenomenon can be the most informative observed on the Earth over millions of years. Over the last 28 years it has been found that there is the changing of the relative deformation and stress state of the Earth’s crust in the Ural underground mines and proved that this is the influence of astrophysical processes in space, and the relative deformation εAF is numerically common to other regions of the Earth.
It has been established that in relative units the radii of the Earth and the Sun vary synchronously and by the same amount. Therefore, the Solar constant and the gravitational constant on Earth are not constant, but change in relative units by the same magnitudes. At extreme values of time variables of stress, catastrophic destruction of ground and underground structures occurs. The situation will escalate by 2020-2024.

Published: April 2020

Abstract
This paper describes the engineering geocryological zoning of the Republic of Sakha (Yakutia) which was performed based on analysis of the main controlling factors and their cartographic generalization. Several schematic maps were compiled depicting topography (landforms), geocryological processes, soils and rocks, permafrost conditions and seismicity. The types of engineering geocryological conditions were assessed and scored to classify areas by suitability for engineering. The paper begins with a brief Introduction which clarifies the objectives and importance of the research. The Methods section describes the ranking of control factors adopted for the convenience of zonation. The next section discusses the factors controlling engineering geocryological conditions in Sakha (Yakutia). The Results and Discussion section describes the series of maps produced comprising: a map of morphostructural zonation, a zonation map of geocryological processes intensity, a zonation map of ground and permafrost conditions, a map of seismic zonation. It also presents an integrated analysis of the controlling factors and concludes that the Coastal Lowlands and Shallow Seashelf Region is most challenging for engineering. For further refinement of engineering conditions, it seems advisable to prepare permafrost-landscape, geomorphological and other regional maps that would be useful for assessing economic feasibility of projected developments in the Republic of Sakha (Yakutia).

Abstract
Pedestrian zones are an important part of urban landscape. Better urban environment is crucial to better living standards. In 2019, the Russian Government allocated considerable budget for urban development in towns and historic settlements. Among other things, urban development efforts comprise the creation of pedestrian zones. Any such effort should be discussed comprehensively with respect to general city planning, neighborhoods, or even applicably to a precinct. This paper describes Voskresenskaya ulitsa in Kaluga as an example of a multifunctional themed pedestrian zone. What makes the street stand out is the abundance of federally protected architectural and cultural monuments. It is located in the downtown, and the surrounding architectures make it a tourist attraction. The paper analyzes a variety of functional layouts for the street. It further makes proposals on how to theme the street.

Authors: Fakhreeva A V , Voloshin A I , Tomilov Yu V , Dokichev V A 
Published: April 2020

Abstract
The research team has obtained functionalized nitrogen-containing polysaccharides based on affordable low-molecular carboxymethyl cellulose. 90 thousands and ethanolamines. The paper shows that due to the specific reversible adsorption that occurs when seeds are nucleating, these polysaccharides alter the shape of the emerging crystal, inhibit the aggregation and agglomeration of CaCO3 crystals, and reduce their size from 49.6 to 20.2 and 15.4 µm, respectively. Gravimetry shows that the corrosion rate of low-carbon steel 20 in a produced-water model is reduced when continuously running CO2 in the presence of synthesized polysaccharides. The protective effect of the functionalized CMC derivatives is 15.8 to 18.6 percent stronger than for the original biopolymer. The obtained polysaccharide derivatives could be of use for developing corrosion and scaling inhibitors.

Published: April 2020

Abstract
Analysing the transportation of goods as one of the constituent elements of the transport system, it can be argued that container transport today occupies a leading position in the delivery of goods throughout the world. According to statistics, the total volume of container traffic in the first two months of 2018 was approximately 26 million TEU (twenty-foot equivalent unit is a conventional unit of measure for the capacity of freight vehicles, namely, a 20-foot container), which is 6.7% more than the same index last year. Positive growth rates of container traffic indicate the relevance and scale of this type of transport. Also, thanks to the rapid development of intermodal and multimodal transportation, the volumes of cargo delivery in containers are increasing. Resulting from this, the container transport system, the main components of which are containers and container terminals, can be considered and analyzed as a technology for the conservation of resources.
