Published: March 2021

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

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

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

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.

Authors: Zelenkovskiy P , Solovieva E , Dubrova S , Sikorsky I , Evenkova T
Published: March 2021

This paper evaluates the ecological and geochemical status of soils in the Opuksky Sanctuary, Republic of Crimea, Russia. The Sanctuary has been a nature reserve since the mid- 20th century. It is located on the Black Sea coast of the Kerch Peninsula, the Republic of Crimea. This is an integrated sanctuary established to preserve the unique steppe ecosystems associated with the limestone massif of Mount Opuk and Lake Koyashskoye, a salt lake which has a number of one-of-a-kind nature sites within a small area and features several rare species. The water area of the Sanctuary is a wetland protected international under the Ramsar Convention. The increasing anthropogenic pressure arising from agricultural and industrial development of the Crimean Peninsula, as well as the increasing tourist flow that must be controlled is what makes monitoring the area critical. Soil is the most sensitive natural environmental component to anthropogenic effects; as such, it was monitored over three years from 2017 through 2019 as part of St. Petersburg State University, Department of Environmental Geology’s student internship co-organized with the administration of the Sanctuary. This effort produced a map of heavy metals in the local soils. The authors described the patterns in pollutant migration; they also prove why the soil was vulnerable to contamination. The research effort was the first to collect data on the background presence of trace elements in the soils of potentially uncontaminated areas; this data could be of use for engineering and environmental surveying across the region. Such data is becoming relevant and essential as the Republic of Crimea’s heavy industry and agriculture are rising.
Influence of Groundwater in the Base of the Gas Pipeline During the Formation of Aufeis
Authors: Permyakov P P , Vinokurova T A , Popov G G
Published: March 2021

Pipelines with a large length in permafrost areas pass through various water passages. In winter, due to various types of waters – underground, river, and lake (often ice has mixed nutrition) – we observe the formation of aufeis. When they repeatedly pour out onto the surface and layer by layer freezing, plane-convex ice bodies are formed – aufeis. The heat and mass transfer interaction of a gas pipeline with a frozen ground base is considered during the filtration of permafrost groundwaters. Numerical modelling was carried out taking into account the real thawing process – freezing of the pore solution in the temperature spectrum at various temperature regimes of filtration of permafrost groundwater. As a result of a numerical experiment, it was established that aufeis formation occurs in the second half of winter and has a warming effect. In the first half of the summer period, intensive thawing of aufeis is observed, and the dynamics of the depth of seasonal thawing occurs with some delay, but at the beginning of the winter period, it is restored, as in ordinary soil. Long-term seasonal filtration of groundwater with a natural temperature of the environment has a warming effect on the temperature regime of frozen rocks. Warming and increased water saturation of the frozen soil base are accompanied by negative seasonal permafrost processes.

Published: March 2021

The article considers the possible consequences of flooding for the ecological state of territories, sets the tasks of risk assessment and prevention of damage from dangerous hydrological processes. The authors discuss possible ecological consequences caused by flooding for ecosystems and built-up areas and suggest methods for risk assessment and risk management in flooded areas. Natural and anthropogenic factors of floods and issues of predictability of hazardous hydrological processes are also considered. The article shows that the risk of a disaster, the initiating factor of which is a flood, occurs when hydro-meteorological, geological and other hazards interact with vulnerability factors of a physical, social, economic and environmental nature. It is proposed to take an extreme hydrological event of low probability as a scenario of a catastrophic event, for example, the historical extreme of the maximum water flow. As an example, we consider the decisions taken to prevent flooding in built-up areas on the example of the Kuban river basin of the Krasnodar territory.
A Socioeconomic Development Concept for Russia’s Specially Protected Areas to Address the Negative Anthropogenic Impact: Evidence from the Tunkinsky National Park
Authors: Afonina T E , Lazareva A A
Published: March 2021

Russia’s natural parks (NP) are critical for the preservation and recovery of the natural environment and biodiversity. NPs were mainly created to preserve the landscape- forming biotopes. Siberian and Far Eastern NPs were founded in the late 1980s or early 1990s. As a result, previously human-populated or otherwise affected areas that contained settlements, logging sites, mining sites, collective farms, and other economic facilities were transformed into national parks. A national park is supposed to provide venue for research and recreation, which is at odds with the locals’ economic activities. Irrational recreational use of NP areas degrades the plant communities: vulnerable species vanish, less vulnerable replace them, and meadow species become widespread in forest ecosystems; it also negatively affects the soil cover as it destroys the ground litter of soils, makes the humus horizon shallow and too dense, ultimately killing the soil microflora. This is the case of nearly any NP in Siberia and the Far East, which calls for well-thought-out economic zoning of areas that would be environmentally, economically, and legally sound. It is on this basis that this paper proposes a socioeconomic development concept (the Concept) for the Tunkinsky NP.

Unique Ecoregion-East Siberian Taiga: Approaches and Ways to Implement the Ecoregion Concept
Authors: Belousova S V
Published: March 2021

according to Russian and international experts, the East Siberian taiga is not only practically the only natural ecosystem in the country, but is also one of the "global ecoregions" that have been identified by WWF as the most valuable territories in terms of preserving biodiversity on a global scale. At the same time, the current use of this territory is characterized as extremely depleted, due to the high level of illegal logging, the scale of forest fires and the current nature of forest management and reforestation. One of the reasons for this is the extremely low efficiency of forest resources management against the background of high corruption of the authorities in this area, which creates additional risks and losses. In these circumstances, it seems necessary to create large-scale environmental conservation project of the East Siberian taiga, perhaps in conjunction with WWF, which implements, including the biodiversity conservation project in the Altai-Sayan Ecoregion. The principles and approaches of the latter within the framework of the forest program can serve as a basis for conservation measures of the East Siberian taiga. The article analyzes the problems and conditions for implementing the main principles of the forest program of the above-mentioned WWF project in relation to the East Siberian taiga and suggests additional measures to protect the unique Ecoregion.

Stability of Artificial Urban Slopes to Mini-Landslides
Authors: Chuchkalov S I , Alekseev V V
Published: March 2021

The growth of cities causes changes in the natural landscape and is associated with the construction of structures on natural and artificial slopes. In this regard, large areas become susceptible to landslide danger. The paper considered slip microslides that appear on the slopes of urbanized areas. The functional dependence of the coefficient of friction in soil on moisture, density and type of soil was obtained on the basis of considering soil moisture as a phase that has interfaces with soil air and the solid phase of the soil. For gray forest and soddy podzolic soils, the values of moisture content (0.30±0.04 m3/m3 and 0.22±0.04 m3/m3, respectively) were revealed, at which the stickiness of the soil begins to affect the friction. Using the obtained dependence of the coefficient of friction in the soil on moisture, density and type of soil, an expression was proposed to estimate the ratio of the thickness and length of a landslide for various angles of slope inclination. The carried out numerical estimates of geometric landslide characteristics were consistent with real landslide processes on artificial slopes of urban planning objects.

Environmental Risk as an Indicator of Sustainable Development of Industrial Regions of Russia
Authors: Sugak E V
Published: March 2021

Analysis of the components of investment potential and investment risk in industrial regions of Russia shows that the most critical for most of them are environmental risks. Therefore, the necessary condition for increasing investment attractiveness and ensuring sustainable development of these regions is the optimization of environmental risks, and the main indicators of their sustainable development can be considered indicators that characterize the environmental safety and environmental risks of the population. However, currently there are no methods for quantitative and statistically reliable assessment of technogenic environmental risks of causing harm to the health of the population of a particular region, taking into account factors specific to this region. To assess and forecast environmental risks, it is proposed to use methods and models of data mining, which use data from long-term observations of the state of the environment and statistical data on the health of the population of these regions.

Published: March 2021

The basis of environmental management is the balance of resources consumed and the possibility of their restoration. In agroecosystems, the main resources consumed are plant nutrients, the main of which is nitrogen. Among the sources of nitrogen reduction, the main role belongs to mineral fertilizers, but the only safe source of nitrogen supply to plants is biological nitrogen.

To increase the activity of symbiotrophic microorganisms and increase the amount of biological nitrogen, biological preparations are used. The action of biological preparations is specific and is determined by agroecological factors, the genotype of plants and the cultivated agricultural crop. The article presents data on the study of the effect of biological preparations (rhizoagrin, azorizine, rizotorfin and huminatrin) on varieties of spring common wheat, oats and pea. The influence of drugs on adaptability is determined, the determining indicators of which are plant survival and grain yield. As a result of the studies, the most responsive varieties were identified for drug processing, more effective drugs, as well as the processing method — separate or joint use.

Currently there are a number of problems in the Republic of Sakha (Yakutia) connected with energy supply to remote residential areas and industrial facilities. Taking into account the logistical difficulties of gasification of remote settlements existing in our region, the authors study modern gasification methods. The object of their study is artificially produced gas hydrates. In order to expand the use of hydrates for storage and transportation of natural gas it is important to take into consideration the features of gas hydrate formation process in high-pressure chambers when laboratory settings of gas hydrate synthesis are being realised. The analysis show that gas hydrates can be prospective and effective new source of energy. In addition, since the territory of Yakutia is located in the permafrost zone, there is a scientific, industrial and socio-economic expediency to study the features of gas hydrates. The following work illustrates the study of ways of natural gas artificial hydrate production, analysis of options of its use as a new energy resource in the conditions of the Far North and the process of its synthesis in Federal Research Center of the Devision of Institute of Oil and Gas Problems of Siberian Branch of the Russian Academy of Science.
The Study of Regional Industrial Structure Resilience to Cyclical Crises

Published: March 2021

When forming economic policy, the question always arises: is there a long-term growth trend in the economy now, or is there a short-term economic growth associated with fluctuations in the business cycle? There are several approaches to answering this question. The first is oriented on the determine the phases of the business cycles. The second approach is to study the long-term growth trend and cycles as deviations from this trend. In modern works, was proved the regularity between the nature of the cycle and the elasticity of substitution of the utility function of a representative agent. In other words, as the economy stabilizes, the risk appetite increases, and it determines the greater impact of external shocks. In times of crisis, when uncertainty increases, on the contrary, the propensity to risk decreases and the dynamics of the cycle becomes more coherent with the long-term development trend. This fact makes considered the infrastructure as a factor of business cycle stabilizer. So the infrastructure should not be considered in the context of a competitive market. Since it is reflecting two types of market failures: technological indivisibility and planned increasing returns on scale. Using the method of mathematical clustering based on data from 2000-2018, the article identifies regions of Russia with different characteristics of the relationship between industrial and transport complexes. Complementing the study with an assessment of the overall dynamics of economic growth, the author identifies key industries and effects that occur in regions of the North-Western Federal District.

Assessment of Options for Substantiating an Infrastructure Project Implementation Plan in the Presence of Associated Risks
Authors: Denisova A I
Published: March 2021

The study describes the approach to drawing up and evaluating project implementation plans in the presence of associated risks. Two alternative approaches to planning are considered and evaluated: network modeling and integer programming. It is assumed that the project risk is associated with a positive or negative event or a combination of them that may occur with some probability during the implementation of the project. Different scenarios are developed depending on the conditions under which risk events occur. The risk value for each scenario is estimated based on the expected values of the project’s financial characteristics. Scenario tests are performed for each approach. The described procedure is checked using an illustrative example of an infrastructure project which consists in laying a section of a gas pipeline on the seabed. A software package for project planning was developed taking into account the associated risks based on a scenario approach using the Python.

In the general security system of the Russian Federation, transport security is given a special place. Improving the legal framework, the emergence of vocational training and certification of persons providing it, equipping the facilities of the transport infrastructure with engineering and technical equipment contributes to the development of the transport system. The article discusses the principles of ensuring transport safety. The concept of non-transport effect is defined and types of transport safety are presented taking into account the nontransport effect. Measures are proposed to ensure transport safety on various modes of transport, taking into account the non-transport effect. Threats to transport security in the Russian Federation by mode of transport: rail, road, air and sea are examined. The indicators of transport safety in the Russian Federation in the period January-September 2019 are reviewed and analyzed. The tasks of ensuring transport safety are presented taking into account the extra-transport effect at transport enterprises.
