Authors: Struchkova G , Kapitonova T , Efremov P 
Published: March 2021

Abstract
Life safety on the territory of the Republic of Sakha (Yakutia) is directly related to the uninterrupted supply of energy and heat, which is caused by low climatic temperatures. Even in Central Yakutia, the average period of temperatures below 0° C is about 210 days, below −20 ° C - 138 days. The minimum temperature is distributed in the range from −47.8 ° C to −60.3 ° C. Under such natural conditions, the release of any object in gas and heat supply chain leads to disastrous consequences. In the year at gas and heat supply facilities, several dozen emergencies of varying severity are recorded, mainly in winter period. The system of oil and gas pipelines laid on the territory of the Republic of Sakha (Yakutia), mostly located in the permafrost zone, is affected by dangerous geological processes, which significantly affects its reliability and safety. For stable operation of oil and gas complex (OGC) of the Republic, an assessment of pipeline state system, based on geotechnical monitoring, is necessary. The monitoring system provides heterogeneous data, the analysis of which helps to clarify the interaction between pipeline and permafrost in various geological conditions, and allows you to evaluate and predict the condition of objects and environment.
Application of Soundproof Planning to Reduce Noise in Residential Building
Authors: Butorina M , Kuklin D , Drozdova L 
Published: March 2021

Abstract
Traffic noise is one of the main factors affecting the population both in Europe and in Russia. To reduce noise in the design of residential buildings, the methods of soundproof planning of residential buildings are used. They must be justified by an acoustic calculation. The currently existing methods for assessing diffraction have a number of limitations. For a correct assessment of noise reduction behind noise-insulating types of buildings, a scientifically grounded engineering method has been developed to assess the diffraction of sound for various locations of buildings relative to the noise source. The method allows to evaluate diffraction with high accuracy. The analysis of the factors influencing the attenuation of noise in buildings, carried out using the developed method, made it possible to assess the influence on the noise attenuation of the geometric parameters of buildings and the gaps between them, sound absorption of the territory and building facades. The results of analysis helped to develop recommendations for noise protection methods of building.
Method for Assessing the Consequences of Natural and Man- Made Emergencies (on the Example of the Siberian Federal District of Russia)
Authors: Knaub R V , Ignateva A V 
Published: March 2021

Abstract
The paper presents a method to assess and forecast consequences of natural and man-made emergencies, based on regions of the Siberian Federal District of Russia. A single common measure for all emergencies can be found only in socio-economic consequences of emergencies — both natural and man-made accidents. This measure is the number of victims, as well as the amount of losses. The calculations are based on the factors that adjust the number of victims and losses from natural and man-made disasters to the population level and prices of 2000. The paper presents some statistics of emergency situations in the Siberian Federal District for 2000–2010. Based on the calculation results, forecast maps for damage caused by natural and man-made emergencies, as well as for total damage for 1960, 1990, 2010–2020, were created.

Published: March 2021

Abstract
In the field of veterinary medicine there are no documents rationing methods for research and diagnosis of emergent diseases of animals, their descriptions, the possibility of using them in various conditions, the disclosure of the phased course of the test, and testing of animals for virus antibodies. For this, it is necessary to create a set of standards in the field of diagnosing emergent animal diseases. On the basis of the Technical Committee for Standardization TC 44 "Technologist", the International Technical Committee for Standardization ITC 534 with our direct participation, draft standards have been created that define methods for laboratory diagnosis of especially dangerous animal diseases in order to ensure food safety. Standards are unified for the countries of the Eurasian Economic Union. Standards regulate guidelines for identifying an agent, collecting samples at the right time, choosing the detection of the virus for diagnosis, determining antibodies. All standards meet the general requirements for regulatory documents.

Analysis of Piping Methods in Permafrost Soils
Authors: Garris N A , Glukhova Z R 
Published: March 2021

Abstract
This article describes the experience of domestic and foreign pipelines operation on permafrost soils. Deformations of pipelines during above-ground and underground laying, as well as development of cryogenic processes in the pipeline running area are noted. Promising methods of laying and operation modes of northern pipelines satisfying the principle of non-invasion of soil and the principle of minimum thermal impact are considered. The surface method of laying a pipeline in areas of frost meets the principle of "minimal invasion" into the soil. The regulation of the thawing halo will allow not only to minimize the effect of thawing and freezing of soil around the pipeline during operation, but also to avoid uncontrolled subsidence and heaving, minimize their value, and exclude karst processes. The surface method of laying a pipeline in an embankment on undisturbed moss cover by self-immersion using operating modes in which technological regulation is carried out reduces the thermal effect of the pipeline on the ground and ensures the restoration of permafrost in winter.

Published: March 2021

Abstract
The increase in power of modern energy-saturated wheel tractors does not allow us to realize all the power through traction, causing an increase in fuel consumption. Therefore, the search for ways to improve tractors of the new traction and energy concept is a vital task.
To solve the problem of implementing the power reserve of energy-saturated tractors, a modular scheme for completing a machine-tractor unit (MTU) based on wheeled tractors of traction classes 1.4 was considered. To increase the technological universality of tractors of traction classes 1.4, a tractor configuration scheme with a technological module based on an easily connectable and detachable linkage design is considered. This allows us to aggregate the tractor both independently with any implement for tractors of classes 1.4 and with a process module with implements for tractors of classes 2-3.
As a result of the studies, a modular layout scheme for the MTU based on a tractor of traction classes 1.4 in combination with a technological module was proposed. The technological module is a single-axle drive trolley-hitch made on the basis of an articulated steering frame equipped with drive wheels. MTU formed after a modular scheme based on a wheeled tractor allows us to use the coupling weight of not only the tractor, but also the technological module with an agricultural implement mounted on it. The weight of the technological module is selected in such a way as to ensure the transition of the tractor to the adjacent traction class according to the type applicable in our country.
Based on the undertaken studies, a reduction in losses to overcome resistance and slipping of propulsors, an increase in the MTU productivity and a more complete use of the tractor engine power were obtained.

Endogenic and Exogenic Hazardous Relief-Forming Processes on Sakhalin Island
Authors: Lebedeva E V , Kazakov N A , Ershov V V 
Published: March 2021

Abstract
Endogenous and exogenous relief-forming processes on Sakhalin Island are very dynamic. This can be due to both geological and tectonic (the position of the island on the border of tectonic plates, the predominance of easily destroyed rocks), and geographic factors (including the active interaction between oceanic and continental air masses and altitude). An active Central Sakhalin fault separating microplates provides primary control over seismicity and can have a noticeable effect on mud volcanism. The activity of a mud volcano, taking into account the impact on adjacent valleys, can affect up to 10 km2. The most common exogenous processes of the island are landslides, avalanches and mudflows. Up to 70% of Sakhalin’s territory is subject to these dangerous processes. They are also often triggered by seismic events. It is extremely difficult to predict the exact location and type of activated processes, as well as the time and frequency of their activation. The proposed map of tension in geomorphic systems makes it possible to conduct a reconnaissance assessment of the region, as well as a comparison between individual zones and determine the most dangerous ones.

Published: March 2021

Abstract
The advantages and limitations of methods and tools for monitoring the main parameters of the sea surface by HF radars are discussed. Methods and technical tools used in the HF range and for monitoring natural environments, including both the marine environment and the ionosphere, are compared. Their main parameters and significant differences of methods, instruments and mathematical data processing are noted. The main characteristics of the WERA and CODAR marine HF radars are given. The results of a two-point trial experiment in the vicinity of Gelendzhik were used to substantiate the methodology and instrumental solutions in order to create a domestic complex of observations in the water area of Novorossiysk. Based on the experiments carried out with both foreign and domestic radars, methods of increasing the efficiency of such radars due to their operation in the entire sounding frequency range are considered. Tests of the prototype of the multi-frequency locator confirmed the possibility of its functioning both in autonomous operation and as part of a geophysical complex, while solving a wide range of problems. In contrast to radars of the WERA and CODAR types, operating at one of the given sounding frequency, measurements can be carried out in a wide frequency range, which makes it possible to construct the fields of current velocities and sea surface waves in an extended range of distances at an appropriate resolution and determine the vertical profile of flows.

Published: March 2021

Abstract
To save genetic diversity of rice (Oryza sativa L.), accumulated in the collections of genebanks and scientific institutions, various methods and modes of seed storage are used. However, in the process of long-term low-temperature storage, there is a loss of seed viability among rice samples. With the aim of a differentiated approach to the choice of conditions, methods and terms of preservation of the gene pool of "Federal Scientific Rice Centre" (Krasnodar), the viability of seeds after operational and long-term storage was studied in 1252 samples of indica and japonica subspecies of 37 varieties. The influence of the temperature regime of seed storage for 3, 5, 10 and 35 years on the viability of the intraspecific diversity of rice is shown. In uncontrolled conditions for three years the seeds lost their germination by varieties by 20-68%, and at a temperature of +4.5 ° C - by 5-13%. After 25 years of storage, the seeds of long-grain samples of the indica subspecies, as well as red-grain and awned forms, had the greatest viability. A clear relationship between grain size and its durability has not been identified. After 10 years of low-temperature storage, rice seeds give full-fledged progeny and retain plant productivity at the level of freshly harvested seeds. From the gene pool of the world rice collection, varieties with greater biological longevity of seeds were isolated.

Published: March 2021

Abstract
The report describes the new supervisory control method for a multi-link manipulator mounted on an underwater vehicle, providing visual control of manipulation operations. The proposed method allows to build complex spatial movement trajectories of a multi-link manipulator working tool along a work object surface, using data obtained from onboard multibeam sonars or technical vision systems. Target designations of the operator determine the trajectory type, its position and orientation in a work area. To form target designations and visual observation of manipulator working tool movements along a given trajectory, a TV camera is used that changes its optical axis spatial orientation. The developed method is implemented in the C++ programming language, as well as numerical simulation of a multi-link underwater manipulator supervisory control in the virtual V-REP environment. To visualize the method, the graphical shell is written using "OpenGL Core".

Published: March 2021

Abstract
The research subject is a mathematical model of municipal solid waste management (hereinafter – MMMSWM). Relevance: the growth of the world’s population and its consumption (primarily, in the Golden Billion countries) leads to a corresponding increase in the amount of solid municipal waste (hereinafter – SMW). This increase is an additional global warming factor. Also, growing SMW requires additional land areas. Since the time of Galileo, science has been the application of mathematics to study any object. In the case of SMW, building and solving a mathematical model of SMW management will reduce the anthropogenic load on Earth. The research objective is to build a mathematical model of municipal solid waste management and propose ways to solve it. The research goal is to perform a literature review of existing mathematical models of municipal solid waste management and suggest a new MMMSWM. The research techniques include retrospective analysis, synthesis, comparison, and methods of the theory of differential equations. The research result is building a new mathematical model of solid municipal waste management, which ensures an acceptable control over the filtrate concentration.

Abstract
Today’s the problem of food security is the object of close attention of the world scientific community and international organizations. Food is the most important material basis for the existence of mankind and a necessary condition for the development of human civilization as a whole. Food safety is the part of the country’s national security; it ensures the life of the entire society and determines the economic, political and social independence of the state. In recent years, there has been a sharp deterioration in the quality of food around the world, which is primarily due to the chemization of agriculture in order to increase production and solve the problem of food shortages. The use of pesticides to control weeds, diseases and pests increases yields, but these substances accumulate in the soil, and through it in crops. However, as a result, pesticides are directly or indirectly introduced into agricultural products and from them into food products. Pesticides are xenobiotics that are foreign to living organisms and are not part of the natural biotic cycle. The consumption of pesticides with food harms human health. Pesticides also play a negative role in the technological processes of food production using microorganisms, for example, in wine-making, pesticides worsen the fermentation activity and the physiological state of yeast. The article presents the results of research on the effect of organochlorine pesticides on biochemical transformations in the process of obtaining apple wine materials.
