Analyzing of the Situation with Forest Fires in the Primorsky Region
Authors: Prikhodko O Yu , Soboleva E V , Pretsiniek I P 
Published: April 2020

Abstract
Forest fire is a terrible disaster. Even a surface fire, leads to the fact that the forest planting passes into the stage of weakened, unproductive, which requires centuries to recover, as a result of the fire, the undergrowth dies, the habitats of animals and birds are destroyed, and the CO2 emission into the atmosphere grows. Currently, information is increasingly being received that many countries suffer from forest fires, Russia among them. The situation with fires in the Primorsky Territory is complicated due to the small number of forest protection, landscape, the large number of abandoned agricultural land and the presence of a large number of forest fund tenants. There is no well-coordinated work on fire detection, patrolling the territory with a small number of forest guards is impossible, satellite monitoring allows you to detect a fire when a deflagration is already gaining strength and it is difficult to determine the accessibility, and often the possibility of access to the fire, by coordinates. Most of the region’s state forest fund has been leased, tenants do not always have good neighborly relations with local residents, if all kinds of conflicts arise, then revenge or set fire to become synonymous with words. And often hiding a crime scene in the forest with a fire is a way to avoid punishment.

Published: April 2020

Abstract
A wide application of the rotary-type machines as actuating mechanisms and driving units in the oil&gas industry stipulates for a special approach towards the diagnostics of the current state of their elements. Roller bearings of such machines are the most critical joints as they are under constant action of significant power and oscillatory loads. Generally, failures of roller bearings cause the destruction of not only the bearings but also the contacting parts. Modern dynamic methods of diagnosing the unit and machine technical state, in particular, vibration diagnostics, allow avoiding emergency and hazardous situations, unreasonable and unscheduled stops and expensive visits of the manufacturer’s specialist.
The article considers the existing methods of diagnosing the rolling bearings state by vibration parameters. As a rule, most modern methods are based on quite precise mathematical calculations of vibration components, require the application of specialized and expensive software and do not provide a possibility to make a precise conclusion on the researched object technical state at practice.
The article considers the method of detecting the technical state of roller bearings which can be applicable in most cases. This method reveals the general forms of spectral modulations, reflecting the presence of incipient and developing faults, and defines the real values of a diagnostic sample - test spectrum, uses very few mathematical calculations and does not require all the standard bearing geometrical parameters during analysis.

Published: April 2020

Abstract
Hydroabrasive treatment technology is widely used for cutting semi-finished products, products, cleaning contaminated surfaces, etc. The main disadvantage of the technology is the high cost of cutting. The abrasivity recovery and recycling used abrasives for cutting process is subject matter of foreign researchers, however, no one deals with this problem in Russia due to its low tonnage. The possibility of recovering garnet sand waste after hydraulic cutting is evaluated and a semi-industrial installation for recovering garnet sand waste is presented in this paper.

Abstract
The research of pollutant transfer process in ice-covered marine water areas has a great practical interest. The understanding of pollution transfer and transformation processes in freeze-up period is necessary in conditions of active development of the Arctic Coast and in design a long-term prediction of water quality. The detailed research of wastewater transfer in ice-covered marine water areas in Russia factually not been produced despite the fact, that in practice all type of coastal outfalls realized in the Far Eastern seas, which freeze-up period during from 4 to 6 months.
The submitted research shows the results of field studies of wastewater outfalls of Vladivostok city. The field studies results was compared with results of wastewater transfer calculations, making by engineering methods and results of simulation, produced by CFD (Computational Fluid Dynamic) models which implemented in the Ansys Fluent application software package. As a result of a comparison of the field study data and calculation results, was found that the official recomendations for calculating wastewater dilution give a significant error in calculating wastewater dilution in case of discharged into ice-covered marine water areas. A positive result was obtained for application of CFD models for research of marine outfalls in periods of water freezing.

Authors: Stacenko L G , Bakhvalova A A 
Published: April 2020

Abstract
The growth of communication networks gradually leads to the fact that they become an integral part of the infrastructure of the city. Depending on the features of the building and the location of settlements, the distribution of communication objects may be formed non-uniformly, which leads to a possible deterioration of the electromagnetic environment. This process is difficult to evaluate and predict. The safe coexistence of transmitting radio engineering facilities and residential and administrative buildings is regulated by sanitary norms and rules. The fulfillment of these requirements must be confirmed by appropriate calculations and direct measurements of electromagnetic fields.
According to the results of computer modeling and control measurements, the article analyzes the parameters of electromagnetic fields created by cellular communication transmitters near residential buildings. It is concluded that it is necessary to introduce construction restriction zones into the draft urban development plan and continuous monitoring of radiation levels in residential buildings.

Published: April 2020

Abstract
The article analyzes the principal issues of forest management. First, we analyze the statutory framework which requires improvement. We also focus on the management targets and principles applicable to the use of forest resources, which also require modification. The author describes the key innovative approaches to forest management based on the improvement of economic, technical, legal, organizational, managerial and other activities required for their implementation. The article quotes the opinions of various scientists engaged in the development projects in forest management and reforestation, and analyzes the problems arising in the process of implementing the right for forest management within the framework of the current civil and forestry legislation of the Russian Federation. With the development of the state and society today, the forest industry remains an important source of economic resources. In Russia, woods are an irreplaceable natural resource with unique ecosystems which should be used wisely. Forest resources are a direct source of income for federal, regional and local budgets. Russia ranks world’s second in forest exploitation, and the distribution of forest resources within the country varies from region to region. Siberia and the Far East have the largest volume of forest resources in the country.

Authors: Chanturia V A , Kovalchuk O E , Morozov V V , Dvoichenkova G P 
Published: April 2020

Abstract
Based on luminophore combination being close to diamond in luminescence parameters, water-organic emulsions were synthesized that modified spectral-kinetic characteristics of low-luminescent diamond crystals. The combination of luminophores was used, including an organic luminophore, anthracene, and inorganic luminophore, K-35, the spectral and kinetic characteristics of which make it possible to achieve the required luminescence values of diamonds and ensure their maximum extraction in existing diamond-containing kimberlite X-ray separation process flows. Non-polar hydrocarbons were experimentally substantiated as an organic medium for the luminophores. Mathematical processing of the obtained results was performed and relationships between the composition of the luminophore combination and kinetic characteristics of the luminescent response were determined.

Published: April 2020

Abstract
The current system of assessment of bottom sediments quality in the Russian Federation is based on overseas standards and/or reference concentrations of pollutants. The use of foreign standards contradicts the legislation of the Russian Federation, and the use of reference concentrations leads to ambiguity of estimates due to the heterogeneity of bottom sediments and natural variability of the content of controlled substances. This paper presents the analysis of existing approaches to assessing pollution of bottom sediments, and the results of theoretical and experimental research, calculations, assessing pollution of bottom sediments of the Zolotoy Rog Bay in Peter the Great Gulf. The necessity for adoption and capture in a regulatory document of regional background concentrations of pollutants in bottom sediments is shown. Guidelines are proposed for environmental assessment of the pollution level of bottom sediments in Peter the Great Gulf, based on the use of integral characteristics and criteria for assessing the degree of pollution of bottom sediments depending on the type of use of the water area.

Authors: Kiryanov A B , Salnikov B A , Salnikov E N 
Published: April 2020

Abstract
The results of stochastic modeling of the influence of positive and negative intratermocline eddies (lenses) on the spatiotemporal structure of acoustic fields in the deep part of the Sea of Japan are presented. The lens shape was modeled by an ellipse. The lens center and the emitter were located on the axis of the underwater sound channel. The vertical distribution of the acoustic field inside the lens was studied at various ranges in front of the center, in the center and behind the center of the lens, as well as at ranges of 40 and 100 km. A negative lens focuses the ray paths on the axis of underwater sound channel at all ranges. A positive lens has a defocusing effect, yet with an increase in range it decreases significantly. The impulse response of the propagation channel was studied on the underwater acoustic channel axis at the ranges of 40 and 100 km. The maxima of impulse response during the passage of the sound emitter through the negative lens shift in time towards increasing, and when passing through the positive lens – towards decreasing with respect to the impulse response of the propagation channel in the absence of lenses.

Abstract
The paper presents the results of assessment of the ecological state of bottom sediments in the Golden Horn Bay based on the integral index of pollution with heavy metals. According to the total pollution index, bottom sediments in major part of the show an average pollution level on Saet’s scale. The most polluted are bottom sediments in the areas adjacent to whaf walls. A significant contribution to pollution of bottom sediments is made by copper, lead, cadmium and zinc. It was found that such substances as cadmium and lead did not enter the bay with wastewater in the period of 2011-2016, which indicates the accumulation of these pollutants in bottom sediments from wastewater that was entering the bay in an earlier period.

The Use of Factor Analysis of the Cost When Justifying the Directions of Innovative Development of Crop Production (on the Example of the Grain Complex of the Pskov Region)
Authors: Voiku I P , Kuchuk V A , Sandu I S 
Published: April 2020

Abstract
Situations of risk and uncertainty create conditions for the development of the modern economy. This increases interest in the method of factor analysis, which allows to clarify the trends of the analyzed indicator, to determine the influence of factors on its decline or increase, as well as to establish reserves for growth or reduction. Interest in the product competitiveness, caused by the level of production expenses, reduces the object of factor analysis to the cost. The results of factor analysis, obtained by a unified methodology, allow us to compare the influence of production expenses on the cost of production both in the scale of an enterprise and in the scale of the region and the sector. Crop production, as the most important sector of agriculture, is no exception in this regard. The presented results of the factor analysis of the production cost of the main crop of the Pskov region show the multifaceted influence of the volume of production and expenses on the cost of grain growing. The results of the assessment of the influence of changes in expenses and production volume on the change in the cost of grain crops cultivation, combined with the indicators of the relative change in the contingent cost of 1 ton of grain crops, allow us to divide the municipal districts of the Pskov region into four typological groups: extensive growth, recession, stagnation and intensive growth. The influence of changes in wages, expenses for seeds, fertilizers, maintenance of fixed assets and other expenses on the cost of grain crops cultivation in each of the four typological groups is illustrated. Since the expenses in crop production are the points of application of innovations, the identified reserves of cost reduction allow us to formulate the main directions of innovative development of regional crop production.

Published: April 2020

Abstract
The transport industry of the Russian Federation in recent years has received significant technological development. The use of modern innovative solutions in the organization of the management process allows you to create SMART-type transport highways, that is, highways for which the social significance of the project is the main criterion for its quality. In this article the quality of the design solution for modeling the transport interchange is considered in two aspects: 1) the quality of the project, independent of its subject area; 2) the quality of the project product, determined by its subject area. At the same time, the critical moment of the quality management of the transport interchange project is the translation of the needs, desires and expectations of participants into requirements (criteria), which must be taken into account when planning the content of the project and its executors. The article proposes the author’s quality management system projects transport interchanges, which operates on the reconciling the needs and expectations of all the project’s stakeholders basis principle and the quality criteria achieved at different phases of the project life cycle. This model can significantly reduce the cost of implementation and future operation of the traffic intersection, since from an economic point of view it becomes, in fact, a self-sustaining subject of urban space.
Methods of Economic Growth Forecasting Using Modified Production Functions with Variable Technical Progress
Authors: Moon De En 
Published: April 2020

Abstract
The article studies the problems and methods of forecasting economic growth based on the traditional production functions (PF) and tools of the modified production function (MPF) with variable technical progress developed by the author. The hypothesis about the variability of parameters in (PF) allows to increase the accuracy of modeling, to differentiate and predict the variable contribution of factors to the increase in production, to transform the functions of linear and power PF. When forecasting of economic growth, the problem of separate evaluation of the variable effects of economic growth, due to the influence of both accounted and unaccounted factors, is actual. Solving this problem will allow dividing economic growth into variable effects and developing appropriate strategies for economic development. The forecasting methods proposed by the author using MPF with variable parameters make it possible to overcome the problems of traditional forecasting. MPF can be reduced to a PF with variable technical progress, which can be used to evaluate and predict the variable effects of economic growth, due to the influence of both accounted and unaccounted factors. The developed forecasting methods allow you to see the price of achieving economic growth and develop a strategy for economic development. The possibility of forecasting using MPF is shown on the example of forecasting the economic development of the US.
Integrated Mechanism for Managing the Development of Offshore Hydrocarbon Deposits in the Arctic
Authors: Fadeev Al , Tsukerman V 
Published: April 2020

Abstract
Recently, in the Arctic zone, including its marine area, the presence of a number of economic entities has already been observed. This is, first of all, transport, the extraction of biological resources, the extraction of aquatic culture, and, finally, the extraction of mineral and hydrocarbon resources. It is worth noting that in recent years, a number of institutions were formed at the state level in Russia to promote business development in the Arctic zone. These are the created State Commission for the Development of the Arctic, as well as the Business and Scientific Councils created under this commission. At the state level, a number of fundamental documents were also adopted (the Strategy for the development of the Russian Arctic and national security for the period up to 2020, the Marine Doctrine of the Russian Federation), which define the development of the Arctic as one of the main priorities of the state policy. Taking into account different directions of economic activities of these business entities, each of which has its own geography and national-international system of regulation and management, conflict of interests is often observed that can lead to very negative consequences for sensitive ecosystems of the Arctic zone and for the development of individual sectors of the economy. In other words, in contrast to harmoniously created natural ecosystems, human activities on the shelf of the Arctic seas do not have a systematic organization, individual industries (transport, production of bio- and aquatic resources, hydrocarbon resources production, etc.) do not form a single systemic commonality. The search and maintenance of such a balance is the main task of comprehensive management of the development of Arctic marine hydrocarbon fields.

Abstract
The paper discusses the methodological issues of assessing the technical and economic potential of the Arctic hydrocarbon fields which can be used to make strategic decisions on the management of the oil and gas sector and the exploitation of natural resources. The sequence of calculation steps of the technical and economic potential of marine oil and gas fields of the Arctic which, unlike the existing ones, is based on an integral indicator that combines the financial, technical, climatic, and service-infrastructure characteristics of the fields what allows rating the fields to determine priority of the start of their development is proposed. The need to take into account a wide range of factors in a comparative analysis of oil and gas fields of the Arctic in order to make strategic management decisions on the priority of field exploitation is proved.
Value and Economic Significance of the Cold for Human Life and Activities in the Arctic
Authors: Nogovitsyn R R , Romanov A R 
Published: April 2020

Abstract
The natural resource of the Cold is often overlooked. The Arctic has it own characteristic features: cold climate, glaciers and permafrost. What is the cost of the Cold, and how can we calculate it? Many problems are associated with the attempts to identify the cost characteristics of the Cold using the methods that are employed to establish the cost of production material resources. The current approach to the evaluation of the natural resources does not allow to adequately assess the significance of the Cold as a natural resource in the society’s life, in particular, in the Arctic. The cost of the Cold can be considered from the point of view of the concepts of the total economic value (TEV). The Cold cost assessment methods cases for the cost calculation of direct and indirect use of the Cold are presented.

Published: April 2020

Abstract
The article describes an approach to the development of a mechanism of strategic development of maritime transport and regional logistics based on the contemporary understanding of the strategy, strategizing, and strategic planning, and the need in such a combination of development determinants that would allow achieving a synergistic effect in the regional and sector-specific space. The author demonstrated that the strategic development mechanism must be intended to create a quality transport and logistics complex and contact groups and have a complex nature. A mechanism of strategic development of maritime transport and regional logistics as a functional target-oriented pattern of interaction of its elements can be divided into a target-oriented subsystem, a wide range of interconnected development instruments for organizational/institutional, economic, motivational, political/legal, sociocultural, and environmental components, and a resource base. This approach was adapted to maritime transport and logistics of the Republic of Crimea.
