Published: November 2019

In the context of reform in the mechanism of ecological civilization in China, delineation and management of ecological redlines is of great significance to maintaining the ecological security of the cities. The geographical focus of this study is Shenzhen – a city with obvious disparity between the state of development and level of ecological protection as well as a strong demand for ecological products. Considering having an accurate boundary of ecological redline, building an operability management system, and shaping measures for implementation and operation, this study uses ArcGIS, a tool of spatial analysis, to study the indicators, methods, and technical processes of ecological redline delineation on the city and county levels. It adopts an integrated assessment approach encompassing multiple ecological indicators and key technologies to explore the scope of ecological redline delineation. The results of this study are as follows: (1) Land delineated within the scope of ecological redline management is spread over a total of 557.47km2, accounting for 28.53% of the city area, which mainly features low mountains and hills covered with vegetation in southeastern and central Shenzhen. It effectively connects with the ecological control line. (2) Some important ecological areas are not covered within this ecological redline delineation due to relatively scattered distribution. However, these areas are a part of the system comprising a pattern of urban ecological security, ecological redline, ecological land outside the delineated redline, and greenbelts within the construction lands. (3) Within the delineated ecological redline, a total area of 9.25km2 is still allocated as construction land, mainly for linear engineering and civic facilities. Therefore, planning is required for re-greening and ecologically transforming these areas for the sake of maintaining the ecosystem.

Authors: Yang Ye
Published: November 2019

Walking is one of the main travel mode for old citizen (over 60 years old) in their daily life, so understanding how the environment characteristics of residential area could effect the old citizen’s physical activities could help the designer to work better on old citizen friendly urban plan. This study attempts to comprehensively and objectively research on the relationship between environment characteristics and old citizen’s physical activities in Harbin residential areas. Spatial feature and traffic management have been thought as the main determinate of walkability of urban space, however physical features and urban design details have been rarely mentioned. Old citizen’s perception has been examined in this study: 15 environment characteristics problems have been identified in the studied residential areas based on the understanding of pervious researches. Through observations and questionnaire surveys, the environment characteristics of each case study were evaluated and the physical problems were discovered. Additionally, old citizen’s perception on the identified problems and their effects on their physical activities of the studied areas were found and defined, in both high and low walkability residential area.

DOMIRISK: A User-Friendly Domino Effect Decision Support System
Authors: Yang Y , Qian Y
Published: November 2019

The continuous development of modern industry has potential hazard, of which domino effect is a major threat that could result in catastrophe. Moreover, domino accidents will endanger the environment and human health. Some decision support systems for preventing the domino effect have been developed, while most of them are too theoretical and have obvious limitations, such as ignoring the influence of personnel, operational, and other real factors in the actual industrial production process. This paper emphasizes the causes of potential domino accidents and the construction of the accident chain. A system called DOMIRISK is designed which can: 1) quantify the domino effect of the entire plant; 2) identify the root cause of potential domino accidents; 3) build the accident chain of domino effect; 4) assess the environmental risk of the domino accident. A chemical plant is used as an example to illustrate how the system provides practical decision support for controlling the occurrence and spread of domino accidents and protecting environment.
The Significance of Low Impact Development on Urban Water Resources
Authors: Wang Chao
Published: November 2019

China is a developing country suffering from severe water shortage. Although the total fresh water resources account for 6% of the total national water resources, China’s per capita water resources are only 25% of the world’s average. As a result, China is now one of the most water-scarce countries in the world. In this context, China’s urbanization level is constantly improving, and in the process of urbanization and urbanization, human social practice has an increasingly greater impact on water resources and the environment. At the same time, urban water logging and other disasters have led to a large number of loss of life and property, which has caused a series of water resources and environmental problems, causing widespread social concern. Sponge city construction is achieved through low-impact development technology. In the design, construction and management of the development process, low-impact development seeks to minimize the impact on water resources, especially to maximize the utilization and control of rain-flood resources. In order to achieve “low impact”, urban development and planning must follow the principle of respecting water resources. The core meaning of the proposal and use of Low Impact Development technology is to respect nature.
Oil displacement by aqueous solutions of surfactants at various temperatures
Authors: Zemenkova M Yu , Kuzina O A , Shabarov A B
Published: November 2019

To generalize the experimental data on the displacement of oil by aqueous solutions of surface-active substances (surfactants) at temperatures of 40, 60, 80 °C, we studied the influence of an additional parameter of the ratio of the work of adhesion during the displacement of oil by water to oil adhesion during the displacement of an aqueous solution of surfactant W = Ww/W. This parameter characterizes the intensity of mass transfer of oil particles from the surface of the rock using surfactants at different temperatures. The parameter W in combination with the capillary number Ca characterizes the value of residual oil saturation in oil reservoirs. A criterion equation is obtained that allows one to calculate the displacement coefficient from two dimensionless parameters: the capillary number and the relative work of oil adhesion.

Published: November 2019

The article presents the results of many years research on the surface infrastructure influence of mining industry of the North Caucasus on biosphere components in its area of activity. Considering that industrial mining of ores on the eastern slope of Caucasus Mountains (Sadonskoe silver-zinc deposit) began in the middle of the nineteenth century by Belgian industrialists and continues to the present. The accumulation of heavy and toxic metals in the soil horizon is shown (2.5–3.5 MAC), creating a real threat to health and livelihoods of the population living here. Fragmentary variability of landscapes, leading to the depletion of biological diversity, up to the disappearance of its various types has been revealed. According to the intensity of dust emission and the share of negative sources participation in the overall balance of dust pollution of the area atmosphere, it has been found that man-made deposits of ore processing waste are potential foci of catastrophic processes in the destruction of fencing dams by mountain streams, as they are located on terraced areas of mountain valleys. It is analytically established that safety, both general and environmental, can be achieved only by eliminating these sources from potentially dangerous places.

Published: November 2019

Recently, the use of halogens and their compounds in industry and the national economy has increased. The halides of the ternary systems Ag – Bi – Li of are insufficiently studied. So, to create semiconductor materials on their basis, the analysis of this system has become very important. In this paper, the character of interaction of the binary sections in the BiCl3-LiCl-AgCl ternary system is studied through a complex of methods of physical and chemical analysis, precisely by differential thermal and X-ray phase analyses. The analysis of the obtained data allowed to establish the eutectic character of interaction in the LiCI-AgBiCI4system. It was confirmed that the addition of AgBiCI4 lowers significantly the melting point of the second component. Also, it was defined as the eutectic character of interaction with limited solubility of the components in the AgBiCI4-LiBiCI4 and AgBiCI4-LiBi4CI13 systems.

Authors: Gadzhiev M D
Published: November 2019

The problem of operating ECP in the zone of low production rates is very relevant for a number of leading oil companies, since most of the wells are operated by such pumps. The adopted values of the boundaries of the working part of the characteristics of the pump are indicators: 0.75–1.25. According to preliminary estimates, 31 % of the ECP at the Tevlinsko-Russkinskoye field are operating outside the operating range, which leads to a decrease in the operating efficiency of downhole pumping equipment (DPE). The average well production rate for oil was 8.6 tons per day, for liquids – 89.5 tons per day, for water content – 90 %. This article presents an analysis of the ECP operation in the Tevlinsko-Russkinskoye field. The work describes the complications of the DPE when it is used beyond the right and left borders of the working area. On the basis of pilot field works, the possibility of using alternative DPE has been described. At the end of the article highlighted the main problems relating to the operation of wells and equipment.

Dust content in the air: A case study of the Afanasyevsky open pit mine (Russia)
Authors: Lemanova S A
Published: November 2019

According to experts, the world consumption of mineral raw materials and the rocks extraction have reached about 12 and 100 billion tons per year, respectively. Overall Russian coal production accounts for 259.9 million tons (according to the Ministry of Energy of the Russian Federation and the ‘Rosinformugol’ agency), metallic ores are estimated at 230 million tons, and building materials reach 1.4 billion tons. The overall growth in mineral production and capacity of ore producers cause an increase in the negative environmental impact of mining extraction and processing. It should be taken into account that due to the depletion of reserves of rich mineral raw materials, the volume of mined rock mass and the amount of processing waste of mineral raw materials increase. It results in the formation of mine dumps, consisting rocks, ore beneficiation wastes, ashes, slags, and sludge. Research data describe critical environmental situation within the mining enterprises, and especially mine dumps, as a result of massive dust emissions. In addition, there is a tendency to further environmental degradation, due to the increase in production capacity without complying with effective measures to reduce dust emissions. Considering the fact that fine particles are priority pollutants in the extraction and processing of mineral resources at mining enterprises, it is necessary to develop new environmentally efficient and economically viable methods of dust suppression.

Authors: Lidzhieva N Ts , Ulanova S S , Ubushaeva S V , Ovadykova Zh V
Published: November 2019

The article presents results of six-year research on the Tsagan-Nur reservoir located on the Caspian lowland. Quantitative values of several indicators were obtained: hydrological (level and area of the reservoir), hydro-chemical (mineralization, chemical elements), environmental (ecotone water-land system). The methodological basis is the ecotone concept according to which there are blocks (areas) experiencing effects of the water body. Analysis of space information showed a significant reduction in the water surface area from 55.4 km2 (1978) to 6 km2 in 2018. Mineralization of the reservoir water increased 7 times compared to the average long-term data (10-12 g/l) and amounted to 70.24 g/l in 2018. Drying and deterioration of the water quality increase the saline area and decrease biological diversity of the flora and fauna, make it impossible to use waters of the reservoir for economic purposes.

Published: November 2019

The article deals with the issue of man-made resources utilization in the form of ceramic crushed bricks and production fault with fine and big fillers for small objects production from the ceramic-concrete. This wasteless technology of wall materials production allows saving the environment. There is a peculiarity of preparing forming ceramic-concrete compositions as well as in structures of these compositions. There are formulas of light-weight concretes based on ceramic brick filler and parameters necessary for quality and durable small-piece materials. Such characteristics as density, thermal conductivity, cold resisting property and compression strength have been studied as exactly these characteristics are under special attention. Developed compositions of light ceramic-concretes had rather low thermal conductivity within 0.49–0.98 Wt/(m·°C), ceramic-concrete type by cold resisting property was within F50 to F100 limits, density changed from 1300-1700 kg/m3, compression strength was 41 MPa. Using crushed bricks in light concretes allows reducing the cost by 30–35.

Published: November 2019

The article presents data on the regularities of the flow of primary succession on the terraces of the tailing dump of the Tyrnyauz tungsten-molybdenum combined plant. In the accumulative ecotope of old-age terraces of the lower level of the dump, grass-wormwood and herb-wormwood communities dominate with a projective cover of up to 60 %. In the transeluvial ecotope of middle-aged terraces, there are ruderal-natural grass-forb grass communities with a projective cover of 37 %. In the eluvial ecotope of young terraces of the upper level, there are monodominant explent communities with a projective cover of 13 %. Old age terraces have the greatest similarity with the zonal flora and have characterics of relatively high species richness and saturation. With an increase of succession length, there are changes in the dominant life forms (from terophytes to hemicryptophytes), a decrease in the proportion of species with wide ranges (pluriregional, holarctic, and palaearctic), an increase in the number of stenobionts and hemistenobionts. A number of species growing in extreme conditions of ecotopes of middle and upper terraces are characterized by the absence of deviations from ecological regimes and indifference to elevated concentrations of Mo and W. High toxicity of the substrate constrains the speed of transition from initial to subsequent stages of primary succession. To restore vegetation, it is necessary to carry out both biological and technical remediation.

Published: November 2019

This paper discusses a variety of methodological approaches to economic and environmental assessment of the negative impact of transport in urban areas. The role of the ecological crisis, which is growing in large cities, is noted. There is a trend of a sharp increase in the number of vehicles in the cities. The need for a comprehensive solution of economic and environmental problems based on the systematic collection, analysis and synthesis of environmental information has been formulated. The foundation for economic and environmental assessment of the negative impact of transport in urban areas is the use of a simulation model based on software package AnyLogic PLE. It is noted that the solution of environmental problems of urban transport is a set of program measures of different nature with the aim to minimize the load on the biosphere. The proposed economic mechanisms and criteria were used in economic and mathematical models, which determined the state of urban ecological systems, and made it possible to make necessary assessment of their sustainability.

Published: November 2019

Snow avalanches and mudflows cause great damage to federal and domestic roads, economic facilities and, most importantly, they are dangerous to people’s lives within the mountainous territory of the Republic of North Ossetia-Alania. Avalanches represent the greatest danger on the northern section of the Transcaucasian highway from the village of Buron to the Northern portal of the tunnel through the main Caucasus ridge, which is 28.3 km long. The number of avalanches is directly dependent on the amount of snow that fell during the winter. During the season of 2011–2012 due to the large amount of snow that fell, there were 371 avalanches (including 270 forcible avalanches and 101 avalanches by self-rising). During the anomalously low snow season of 2013–2014, there were only 13 avalanches, which came off. Therefore, that is the lowest index since the avalanche period of 1986–1987. During the study period, the road was closed from 1 to 17 times per season, which also depends on the number of avalanches. Mudslides pose a great danger to the population of the republic, roads and objects of the national economy. There are mudslides after heavy precipitation on the territory of the republic.
Impact of the expropriation of the territories of natural reserves for mining purposes on protected populations
Authors: Vasilyev M D , Vasilyeva NV , Matveeva OI , Trofimtsev Yu I
Published: November 2019

The paper discusses the impact of allocation of resource reserves for the development of mineral deposits on protected populations. The main method of assessing this effect is mathematical modeling. The results of the study were obtained using a model based on two parabolic partial differential equations (diffusion equations). The equations describe the dynamics of a population in a bilocal habitat, when the boundary of the protected area divides the area into two parts–protected and unprotected. At the same time, the species are free to pass from one part of the habitat to another. The model also takes into account the diffusion movement of species across the habitat and cross-diffusion, which means both the competition of species for available resources and their possible coexistence. Numerical calculations demonstrate that with a proper assessment of the impact on the natural potential of the reserve, it is possible to maintain stable densities of protected populations in both parts of the habitat, but at a slightly lower level. The case of high man-made loads on protected populations leading to their degeneration is also considered. The work shows that the presence of a sufficient food resource has a beneficial effect on the density of the protected and unprotected parts of the population.
Heat pumps as alternative energy sources: characteristics, state and prospects for use
Authors: Tsgoev T F , Tebloev R A , Dzhatiev O B , Zagalova L A
Published: November 2019

Currently, heating and hot water supply of urban facilities is provided, as a rule, by centralized heating systems. The source of thermal energy in such systems are city combined heat and power stations (CHPs) – which combine generation of electricity and heat – or district boilers. The benefits of centralized heat supply are widely recognized. However, their use also has drawbacks and limitations. The construction of extended heating mains to remote objects, as well as to objects in areas with low building density, is associated with significant capital investments and large heat losses along the mains. Their total operating expenses are significant. Serious problems also arise in the reconstruction of existing facilities and the construction of new ones in populated urban areas with dense buildings. The current tariffs for thermal energy, combined with the cost of connecting to the urban heating networks, make it increasingly necessary to think about alternative methods of heating. In addition, a large amount of fuel is burned at CHPs and boiler houses, which adversely affects the environment. A modern rural house is mainly heated from autonomous boilers, private heat generators, or stove heating. Solid fuel is traditionally used as energy in the stoves. The stove usually has a firebox (where fuel is burned), channels through which flue gases are transported, and a chimney that removes flue gases to the atmosphere.

Reducing the incidence of miscarriage in order to improve the demographic situation is currently one of the most pressing problems. The article presents the results of a comparative statistical analysis of reporting forms of federal statistical observation No. 13 “Information about pregnancy with an abortive outcome”, No. 32 “Information about medical care for pregnant women, parturient women and puerperas” with an insert for it “Information about the regionalization of obstetric and perinatal care in maternity hospitals (wards) and perinatal centers”, data from the State Report “On the state of sanitary and anti-epidemic well-being of the population in the Republic of North Ossetia-Alania in 2018” and statistical yearbooks of the Republic of North Ossetia-Alania. It was revealed that in the Republic of North Ossetia-Alania from 1991 to 2018, due to the introduction of modern methods of diagnosis and treatment of women suffering from miscarriage, as part of the state’s policy in the field of women’s and children’s health, a significant decrease in infant and perinatal mortality occurred at practically the same frequency of a miscarriage. The latter was the basis for the assumption about the negative impact on the reproductive function of women of a high content of heavy metals in the soil, in particular cadmium and lead. It is concluded that it is necessary to conduct active monitoring of the content of heavy metals in the serum of women of reproductive age.

Published: November 2019

One of the most serious obstacles of a natural character for the development of recreation and tourism are natural hazards and processes. The high-mountainous part of the republic is especially subject to such processes, where most of the recreational objects are concentrated. Of the entire spectrum of hazardous natural processes, mudflows, avalanches, landslides, karst, subsidence, slides, debris, flood and flooding are the most widespread in the republic. In the mountainous part because of strongly dissected relief with steep slopes and considerable depth of incision of narrow river valleys, avalanches, mudflows, landslides and debris, slides, glacial activities are most active. The flat part and the foothills have their own set of natural hazards, among which floods, flooding, subsidence, soil erosion, and droughts prevail. These areas are often exposed to hailstorms. The entire territory of the Kabardino-Balkar Republic is an area of seismic activity. Spontaneous natural processes and phenomena have the most significant impact on the live of the population of the republic and the functioning of recreational facilities located in the zone of their occurrence. Each demonstration of risks in recreational areas leads to undesirable consequences, from dissatisfaction with rest to death of people and wealth.

Authors: Balabanov Vadim , Protsenko Maxim
Published: November 2019

The experience of using hydrolytic lignin in domestic and foreign literature allows us to consider it as a stabilizing additive in the production of crushed stone-mastic asphalt concrete mix. For this purpose it is necessary to conduct laboratory tests of raw materials and asphalt concrete mixtures with different percentage of hydrolytic lignin. On the basis of the obtained results, to draw a conclusion about the use of waste from the hydrolysis industry for the device of the top layers of coatings from rubble-mastic asphalt concrete at construction, reconstruction, overhaul of highways. Stone mastic asphalt (SMA) - artificial road-building material, which is a mixture of mineral materials (rubble, sand from screenings of crushing and mineral filler), oil road bitumen, used as a binder and stabilizing additive used for resistance to delamination and uniformity of SMA. Hydrolytic lignin is a waste of biochemical production of cellulose. Application of hydrolytic lignin as a stabilizing additive for stone-mastic asphalt mixture (SMAS), allows to stabilize the crushed stone-mastic asphalt concrete mix, to increase the adhesion of bitumen to the surface of the mineral material and to improve the physical and mechanical properties of crushed-stone and mastic asphalt concrete. At the present stage of scientific and technological development, economy and rational use of material resources is becoming the main condition for increasing production efficiency. The use of hydrolytic lignin as a stabilizing additive will improve the performance properties of crushed stone-mastic asphalt, as well as reduce the cost of construction, reconstruction and overhaul of highways.

INRTU campus development strategy
Authors: Bolshakov Andrey
Published: November 2019

Three models of university spaces could be considered. A dispersed model is historical universities integrated into the urban building layout with academic buildings and residences scattered throughout the city. The second model, the opposite one, is an autonomous suburban campus. Core functions are compactly located on a large site: study-residence-recreation-suburban campus in natural environment. INRTU refers to the third model: this is large campus with a full range of educational and residential functions integrated into the city. The arterial street and the bridge adjoin the site. However, the problems could be observed: lack of functions organization, places and internal street network. The university is beneficially located on the river bank, but does not provide access to it. It is interfered with low value individual building and railway. The campus suggests real opportunity to form a full-fledged recreational framework of the territory – a green cross, but garages and parking lots provide an obstacle. It is necessary to form a dense internal street network to ensure the presupposed level of territory coherence, and on its basis to build and develop technology parks, cultural center for young people, a water-sports and information-library complexes in the form of detached buildings. To form the university embankment. To overcome the environment fragmentation, and establish effective connections with adjoining universities and the academic center.

The behavior of the steel I-beam with plate corrugated webs in conditions of restrained torsion is considered. The problem is solved numerically in the «ANSYS 14.5» software package based on spatial model where finite elements of shell type are used. Results obtained allowed us to calculate geometric characteristics of web beams associated with torsional deformation in order to continue to perform the calculation of these beams on the rod model. Analysis was made using two models of corrugated web I-beams with different corrugation configurations with geometric parameters and giving similar values of metal. A comparative analysis of the stress-strain state of corrugated beams and I-beams with flat web at torsion with bend.

The effective system of secondary and higher education is becoming an essential element ensuring competitiveness of the national economy. At the same time, this system cannot be based only on investments in education. If there are no institutional investments in education, government investments, no matter how large they are, will not help achieve the desired results. Private companies do no invest in education at all. One of the most important conditions for effective educational services market is full-fledged competition in the labor market. Companies as buyers of the final product (specialist) should compete with each other. This is a prerequisite for the development of competition between providers of educational services – Institutes and Universities. Competition between institutions will increase the level of qualification of specialists (quality growth) and correspondence between the professional structure of specialists and the structure of jobs in the labor market. This will happen if the sellers copy the most successful patterns of behavior of those the sellers who have achieved commercial success in the market of educational services. Finally, there will be competition between applicants for the purchase of educational services, which will effectively adjust the policies of sellers – Institutes and Universities. When training specialists, Russian universities focus on requests coming from the institutions (government and quasi-government structures) having high budget revenues rather than on the market needs. This refers to numerous state and quasi-state structures. These customers can significantly reduce efficiency of the higher education system.
