Russian and Global Experience of Developing the Regulatory Framework for the Technical Regulation of Architectural Design
Authors: Chechel I P
Published: April 2020

Results of construction, i.e. buildings and related structures, must conform to the public demand to the quality of newly-built objects, their physical, sanitary, and environmental safety. National technical regulation systems are intended to ensure these conditions. To be successful, a system must be legally supported, well-structured and time-tested. An adjusted system does not impose requirements onto construction players, but employs mechanisms to control compliance with such requirements and assess regulatory compliance of controlled objects and subjects. Furthermore, the system ensures favorable conditions for economic wellbeing of the territories where a controlled objects is constructed through the balance of public interests regarding safety of such objects and private interests regarding their cost-effectiveness. Studies of experience of technical regulation of the construction sector in economically developed countries clearly demonstrate that technical regulation objectives are the same regardless of forms of national technical regulation systems. The systems developed in different countries are mostly national phenomena and are differently structured. Each state has a unique regulation model reflecting peculiarities of establishment and development of the legal system, organization of the state structure and public administration, national traditions, level of technical development of the construction sector, and general level of qualification of human resources. National systems reflect the multitude of ways, methods and means of completing technical regulation objectives in the sphere of construction. The article describes regulatory frameworks of technical regulation systems of a range of Western and European countries and of the Russian Federation. This country covered a long way and continues to develop and improve as regards technical regulation. According to the author, new forms and principles of establishing, developing and structuring regulatory frameworks are needed, which is why there are indisputable interest and use in analyzing global experience. This will help to adapt the best global practices in the regulatory sphere to the general system of technical regulation of the Russian Federation and establish a modern regulatory platform on the new evolutionary level. Analysis and evaluation of how effectively current national technically regulation systems performs helps to present the author’s point of view on the further improvement of the regulatory framework of the system of technical regulation of construction in the Russian Federation by creating a new organizational model of this structure to be developed according to the performance-based principle and contain combined blocks of normative standards enforced by different agencies and applied both to the building in whole and its elements in particular.

Authors: Shevkun E B , Leshchinsky A V , Lysak Yu A
Published: April 2020

The article deals with improving the quality of fragmentation of rocks by blast due to increase in intervals of delay. It shows the change in understanding of the mechanism of rock destruction under the influence of blast loads in recent decades. The mechanical effect of blast loads is manifested not only in crushing of rocks, but also in the weakening of their strength in remote distances from a charge. In the area of the blast wave compressive and tensile loads lead to the development of existing micro-defects and micro-cracks. The rock mass changes its strength properties, passes into a new state, called pre-destruction. The increase of delay time between blasts of charges increases the overall time of the blast, contributes to the merging of cracks and a gradual decrease in the sizes of the structural elements of the rocks. Impact on rocks alternating loads up to 20 or more times allows to increase the distance between the charges.
Error of Altimetric Determination of the Wind Speed over the Ocean, Caused by Dominant Waves
Authors: Zapevalov A S
Published: April 2020

The analysis of the error in the restoration of wind speed according to altimetry measurements is performed. For analysis, a spectral model of the field of surface waves was used. The model takes into account changes in the field of surface waves at different stages of its development. A factor that reduces the accuracy of measurements is the ambiguity of the relationship between wind speed and the variation of slopes created by long waves. It is shown that when sounding in the C band of radio waves, the error in measuring wind speed is about 2 times higher than when sounding in the Ku band. It is also shown that at a wind speed of less than 15 m/s, the influence of long waves on the accuracy of altimetry measurements of wind speed can be neglected. At a wind speed of 30 m/s, estimates of wind speed obtained from altimetry measurements may vary by 0.57 m/s when probing in the C range, and by 0.27 m/s when probing in the Ku range.

Authors: Vorsina E V , Moskalenko T V , Mikheev V A
Published: April 2020

The article presents the research of absorbent qualities of carbon materials generated by an alkali activation of lignite from the Kharanorsk deposit. The mass ratio of potassium hydroxide/lignite RKOH=1 g/g under thermal impact and further thermolysis for 60 min at 800 °C allowed to create samples with almost 100% iodine absorbent activity (1000 mg/g). In order to improve economic and environmental performance of absorbent production with lignite activation by potassium hydroxide, the research explored qualitative characteristics of absorbents generated with RPH< 1 g/g: 0.25; 0.5 and 0.75 g/g. It has been established that if the ratio of KOH/lignite is lowered to 1.0-0.25 g/g, the absorbent activity for iodine reduces without any significant impact on the output of the product. The iodine adsorption activity for generated carbon materials at RPH< 1 g/g meets the requirements for this indicator of industrially produced activated carbons that are in demand in the market. To generate absorbents from Kharanorsk lignite with iodine adsorption activity not less than 40%, the recommended ratio of KOH/lignite RKOH=0.25 g/g and the duration of isothermal exposure is t=30 min; NTL 80 % - RKOH=0.5 g/g and t=30 min; NLT 90 % - RKOH=1,0 g/g and t=30-60 min.

Authors: Korshunov A A , Nevzorov A L
Published: April 2020

European North with a low population density and poorly developed transport infrastructure, it is difficult to organize waste removal and storage at large landfills, therefore many settlements have small landfills of municipal solid waste (MSW), and the practice of placing them in marshes is very common, which leads to the migration of pollutants into adjacent water bodies. Systematic monitoring of the environmental in the vicinity of such landfills is hampered by high costs of periodic water sampling and chemical composition analyses. It is possible to decrease the number of substances under analysis and thus reduce costs by determining the marker substances, the concentration of which in groundwater near the landfill has stable correlations with the content of other pollutants. The article provides results of cluster analysis made it possible to identify marker substances. To assess the extent of groundwater contamination at landfills of the Arkhangelsk region monitoring of solid waste landfills was organized, which included sampling and studying the chemical composition of the samples. The results of the study have shown that the dependences obtained are applicable for a large landfill in the capital of the region – the City of Arkhangelsk, while for landfills in small settlements the dependences need to be adjusted.

Authors: Shpakova R N , Kusatov K I , Mustafin S K
Published: April 2020

Studies of long-term fluctuations of the river flow are of interest with regard to causal relationships and associations between the climate changes and water regimen of the rivers. It is important to minimize the negative effects associated with fluctuations in the river flow based on long-term predictions of the water contents. Long-term and very long-term predictions of the water contents require understanding of the nature of the long-term changes in the water contents of the rivers. Investigation of the spatial trends in changes in the river water contents is important. It was established that there was an increasing straight-line trend of change in water content for the majority of the rivers on the territory of the Republic of Sakha (Yakutia) during the period from 1964 till 2015. Mapping of the slope factor of the linear trends allowed to determine the main regularities of the spatial breakdown of the type of perennial change in river flows. Besides, smoothing of the time series of the river flow by the method of 20–year sliding linear trend in a span of twenty years allowed to establish the types of perennial change in water content for each water body with further zoning.

Authors: Kukleva N V , Kuklev D N
Published: April 2020

The development of railway high-speed passenger traffic in Russia under conditions, when the construction of a high-speed line is still at the stage of justification, is an actual and rather difficult task, requiring a thorough feasibility study. This task is sometimes even more complicated than the construction of a new line for the implementation of high-speed traffic, as it requires taking into account a large number of factors, for example, procedure of construction work at a large number of separate points with track development, even small ones, of intermediate stations and divert stations. As a suggestion, the authors review, as an alternative to reconstructive measures, the principle possibility of using detours for the passage of high-speed passenger trains, which in practice are often used for transit traffic organization, more often freight traffic, less frequently – passenger traffic. Previously proposed typical schemes of the conversion of intermediate separate points with track development for high-speed passenger traffic are being analyzed; conclusions about the possibility of using bypass lines instead of reconstruction are being made. The article may be useful to specialists, who make researches in the sphere of high-speed passenger traffic organization from the point of view of preparation of existing highways in general, and railway stations in particular.

Authors: Parshin A V , Budyak A E , Babyak V N
Published: April 2020

Low-attitude remote Earth sensing (RES) performed by unmanned aerial vehicles (UAV) helps run geological surveys more efficiently; aeromagnetic surveys have been on rise recently. UAV surveying can be made significantly more informative and cost-effective by switching from monomethod surveying to integrated efforts that combine multiple complementary methods. However, how to run such surveys efficiently is a question barely covered in special literature. This paper uses evidence from a site in Bodaybinsky District (Eastern Siberia, Russia), a promising black-shale gold mineralization site, to analyze a typical geological exploration case, namely additional exploration of underexplored areas near a known deposit. It considers a method for integrated UAV geophysical surveying and its interpretation; this multi-method approach comprises aeromagnetic surveys, gamma radiometry, and multispectral photography. Emphasis is made on how important correct interpretation of geophysical data is for the latter. The paper shows that such photography is necessary for identifying man-affected segments in the area and for assessing the distribution of vegetation in it; this helps adjust the gamma background charts. Use of integrated low-altitude surveys taken from UAVs helps quickly and cheaply identify potential gold-bearing sites by a set of indirect features. Exploratory drilling has proven the approach effective.

Published: April 2020

The results of numerical modeling of frequency dependence of permafrost surface impedance in a band of 1 Hz to 100 MHz are shown for typical geoelectric sections (GESs) of Central Yakutia. Particular qualities of frequency dependence are represented by oscillation values in a wide frequency band. The role the displacement and conduction currents in permafrost for the given range of frequencies play is marked. Two main bilayer models of permafrost are discussed: weak-inductive and strong-inductive models. Additional three-six layer models are considered along with indication of their particular qualities and conformity with natural sections. The influence of effect of thin conductive layer in permafrost is shown by sites long half-period occurrence of oscillation of impedance’ module and argument values, caused by displacement currents predominance in the horizon of frozen mellow sediments and by conduction currents outweighing in the underlying horizonю One marks the significance the phase curves when used for determination of GES type under condition of approximate automatic interpretation of radio impedance and RMT methods data.
Environmental Education and Management: Exclusive, Inclusive, and Indigenous Doctrines
Authors: Akhmetova A I , Kolomiyets O M , Arpentieva M R , Golubchikova M G
Published: April 2020

Environmental education of the population is an important part of environmental management. Environmental education is necessary not only for entities directly involved in the processes of nature protection (environmental performance) and in processes harmful to nature (use and processing of resources and waste management of industrial technical and agricultural production and domestic consumption of production products). It is necessary for all people, including as subjects included in different types of relationships and in various systems as direct participants in environmental protection measures and/or victims of natural disasters, as stakeholders and as representatives of indigenous cultures, etc. In Russia an exclusive doctrine has been established nature conservation: the leading role was played by states that determine the forms of protection and exploitation of natural resources, the development and compliance with environmental standards, and the requirements for environmental education of the population. Other model is in addition to the system of national parks and other protected areas, indigenous community protected areas are formed and developed. Thus, not only the doctrine of an isolating type (care of nature is the concern of the state, not of man) is popular here, but also the indigenous, participatory doctrine (“live on your land - study it and take care of it”). This model assumes a systemic, multi-level and multicomponent interaction of subjects of various types, relatively clearer than in the first case, ideas about personal, group and organizational responsibility in the field of nature protection. In the intermediate phase of the transition from one doctrine to another, there is an inclusive model. The basic principle is everyone cares about everything. In this case, the search for productive and effective management systems and the development of the ecological culture of individuals, groups and organizations is usually observed.

Mathematical Model for Determination of Liquefied Natural Gas Density by Its Parameters and Composition
Authors: Shalovnikov E A , Prakhova M Yu , Khoroshavina Ye A
Published: April 2020

Liquefied natural gas (LNG) production and export are becoming one of the most strategically important segments in the Russian gas industry, and therefore the maintenance of LNG production and transporting infrastructure is deemed a critical problem. The commercial accounting of LNG is carried out in the tankers of LNG marine vessels using the static method. The shifting to the indirect dynamic method used in commercial accounting for other liquid hydrocarbons is hindered by the lack of a change measurement chain for flow and density transmitters. The regulatory documents recommend defining the density through calculations using the modified Klosek-McKinley method applied to the LNG composition, which leads to certain difficulties. This article offers a mathematical model for the calculation of density using the compositional analysis and the state parameters of LNG. The adequacy of the model was tested on five LNG mixtures with different compositions (from 72% up to 90% methane), temperatures (from 110 K up to 130 К), and pressure (from 0.08 MPa up to 0.4 MPa). In all cases, the calculation error did not exceed 0.15%. Using this model will help to shift to the dynamic method of LNG commercial accounting. It can also be used for forecasting density values based on changing LNG parameters, which can be useful during overseas transporting and reservoir filling in order to increase the safety of these processes.

Potential of the Advanced Special Economic Zones as local growth poles in the Russian Far East
Authors: Leonov S N
Published: April 2020

The Advanced Special Economic Zones (ASEZ) are a relatively new local instrument for implementing the state regional policy in relation to the Russian Far East, aimed at local selective support of the regions and the development of export-oriented sectors of the economy. The management of ASEZ is managed by the Far East Development Corporation (FEDC), which provides residents with a full range of consulting and organizational services, carries out infrastructure construction and examines applications from potential investors for obtaining resident status in the zone. Statistics of the number of residents of ASEZ are based on registries compiled by the FEDC. The total number of ASEZ residents in the Far East shows a positive trend - 331 residents in 18 ASEZ in eight territories of the Far East in early 2019.An analysis of residents by territories and industries revealed the attractiveness of ASEZ established near major cities and the propensity to develop the services sector. There was no apparent orientation of residents of the Far Eastern ASEZ on the production of export products. It is shown that the enthusiasm for the creation of advanced development areas in the Far East has created inflated expectations from their implementation. At the same time, none of the ASEZ created in the Far East demonstrated the real effect of the diffusion of innovations. The analysis of the results of creating ASEZ is aggravated by the lack of information and methods for assessing the role of administrative preferences provided by the territorial authorities for the implementation of regional projects. In order to properly assess the effectiveness of the functioning of Advanced Special Economic Zones, it is necessary to conduct additional research, which is currently hampered by the lack of information in the registers of ASEZ residents on the scale of their business (investment volume, number of employees, expected and actual production or sales).

The concept of social and technogenic development was proposed by the Doctor of Philosophy Professor Eduard Semyonovich Demidenko in the depertment of Bryansk State Technical University exactly called Scientific and Philosophic Research School of Social, Technogenic and Natural Processes and Social and Technogenic Development of the World in 2002, which became quite well-known in the Russian Federation and is recognized by RAS, RAO, RAE, REA, MAI, Moscow Society of Nature Employers, established in Moscow State University named after M.V. Lomonosov in 1805. On the basis of this school the scientific and philosophical field-philosophy of social and technological development of the terrestrial world is developing. In recent years, E.S. Demidenko has paid special attention to various aspects of the life evolution on Earth and the need to form a long-term strategy for the development of Russia. He proposes the most likely, in his opinion, safe and promising scenario of escape from the deadly danger to humans and the biosphere, which (danger) comes from spontaneously chosen by mankind social and technogenic development of the world. He is talking about strategic, fundamental and generalized ideas, on the basis of which the social, technogenic and biosphere model of life will be consciously built.

Published: April 2020

This article analyzes the relations between the energy intensity of the economy and the amount of pollutant emissions in the atmosphere. The authors reviewed the main global trends in the field of emissions of pollutants and energy intensity of the economy. The authors also determined the specifics of the Russian economy regarding the structure of energy consumption and the main directions of energy intensity reduction. The study analyzed key indicators of the energy intensity of the economy, the structure and dynamics of consumption of traditional fossil fuels and renewable energy sources. The problems of the growth of pollutant emissions in Russia were considered also. The authors analyzed the dynamics of the emission of pollutants by the main sources of pollution: industrial sectors and automobile transport. The article also analyzed the structure of the growth of pollutant emissions in industries (mining, manufacturing, production and distribution of electricity, gas and water), as well as in road transport. An important aspect in the field of improving the environmental efficiency of production and reducing emissions of pollutants in the atmosphere is the cost of protecting the environment. The main trends in changing the level of environmental protection costs in industrial sectors were identified. Based on the analysis, the authors made conclusions about the nature of the growth of pollutant emissions in industry and road transport based on the analysis.

This paper is devoted to a comprehensive analysis of the impact of foreign investment on the development of the oil and gas sector in Russia, which includes both directions: the impact of foreign direct investment inflows on the production and economic indicators of the oil and gas sector of Russia, and the effect of these indicators on foreign investment inflows. Foreign investments are the driving force in the development of the Russian oil and gas complex and the economy as a whole. So it was until 2014, today’s situation has changed somewhat: the influx of foreign investment in the energy sector of is complicated not only by imposed sanctions, but also the main obstacle - the instability of world energy prices. The current price environment, as well as the supply and demand situation are pushing foreign investors to reduce the investment proposal. Today, the fuel and energy complex, and especially OGC, plays a huge role in the socio-economic development of the country and the increase in GDP, which determines the purpose and objectives of this study.

Authors: Popov P V
Published: April 2020

The article is devoted to solving the actual problem of the construction of the linear multiple regression model, establishing the relationship between the economic indicators of the Russian Federation and the logistics infrastructure of the Federal districts. The obtained equation allows to identify the objects of the logistic infrastructure that have the greatest impact on the dependent variables, and to assess the degree of contribution of each component to the change in the resulting variable using multiple regression. The solution to this problem can be used in the elaboration of integrated development plans for the Federal districts of the country. The methodological tools of this study includes correlation analysis, Kolmogorov – Smirnov test, multiple regression analysis. The values of the indicators are taken for the period 2004-2016. As a result of the study using the IBM SPSS Statistics 20 program, the objects of the logistics infrastructure of the Federal districts that have the greatest impact on the economic performance of the Russian Federation were identified. It is shown that the transport and logistics infrastructures of St. Petersburg, the Krasnodar Territory, the Kirov, Sverdlovsk and Novosibirsk Regions as well as the volume of imports of goods in the Stavropol Territory and the number of transport enterprises in the Republic of Dagestan have the greatest impact on the dependent variables. An increase of the dependent variables by one percentage point will lead to an increase in the economic indicators of the Russian Federation from 0,74% to 1,01%.

The authors devote the paper to the research of the competitiveness level of the Belgorod region on the scale of the Central Federal District. When transitioning to market relations, regions, as independent economic entities are endued with essential functions, the realization of which is conducive to the formation of a socio-economic and legal environment. It guarantees business and commercial structures reliable support in terms of social, economic and environmental security, and competitive recovery of a regional system as well. With the help of a well-known assessment method, 17 indicators were used in order to assess the position of the territory with regard to other subjects on the basis of statistical data. The analysis of main indicators of the Belgorod region’s competitiveness has shown that in the period under study there is a positive trend in the change of most indicators of socio-economic development and competitiveness. According to a number of indicators, such ones as gross regional product per capita, volume of own-produced dispatched goods per capita, cash income per capita, retail trade per capita, total living space per capita, paid services volume per capita and infrastructure capacity the Belgorod region ranks among the top five. The most unfavorable moment is the last place in terms of “the proportion of the population with cash income below the subsistence minimum in the total population of a subject.” Having summarized the aforesaid, we can draw a conclusion about the high level of the Belgorod region’s competitiveness in the scale of the Central Federal District.

The study is devoted to the theoretical justification of procedures and algorithms for managing the quality of products. The methods to control the abstract object are used. Since the object itself, for example, quality is a reflection from the material carrier: products and the production process, control and disturbing influences are attached to them. Control actions are divided into three types: parametric, structural and organizational. The first two types are associated with the flow of technological processes, and due to the application of managing organizational influences, the necessary external and internal conditions are achieved that increase the quality of products. It is shown that even a simple linear formulation allows us to pose and solve the optimal control problem and obtain practically important results.
