Published: March 2021

Abstract
The article discusses the use of machine learning to obtain predictive data of cone penetration tests of soils using the example of studying the geological environment of the Kazan city. The cone penetration test is one of the most popular and widely used types of field tests of soils. As a source material, a database of the physical and mechanical properties of soils and the database on cone penetration tests of soils of various genesis were used. The territory of the city of Kazan was considered separately for each terrace of the Volga river in accordance with the basic principles of engineering-geological zoning. For modeling of the dependence of parameters of cone penetration tests on soil properties was performed using machine learning. Mathematically, the problem was formulated as regressive - need to find functions that closely approximate field test data. As a result, it was found that the dependences obtained as functions of the cone resistance qc have very good convergence. This shows a good prospect of using machine learning to obtain real correlation dependencies, and therefore, to reduce the cost of engineering-geological surveys.
Changes in the Behavior of Long-Term Waterflow Variations in the Middle Part of Yakutia under the Global Warming Conditions
Authors: Shpakova R N 
Published: March 2021

Abstract
Currently, not only the expected future climatic changes but also the associated changes in the long-term waterflow regime are popular research objectives. However, such studies, as a rule, are focused on large water bodies of a regional or even subplanetary significance. Also, the estimates obtained for the expected changes in the waterflow regime are of the most common nature. They are certainly important in terms of assumptions on the main trends in the development of the situation with water resources on a macro-regional scale but do little in assessing the risks of water use or even living safety (if people live near a water body) in the foreseeable future in respect of relatively small and medium-sized water bodies. The study identifies and evaluates the specifics of the waterflow regime response to global warming for rivers, the basins of which are compactly located within a single natural and climatic zone - the middle part of Yakutia. This approach allows adequately comparing the parameters of changes in the behavior of long-term waterflow variations for different rivers.
For all rivers in the middle part of Yakutia, a significant increase in water content has been detected after 1987 (taken as the year preceding the start of the climate warming period), however, for the rivers of the western part of the region, this increase is associated not with a change in the behavior of long-term waterflow variations but with the onset of a high-water phase of a long-term natural cycle there. An increase in the annual waterflow variations was recorded for almost all rivers.
Changes in the behavior of long-term waterflow variations after 1987 led to the loss of stationarity of the annual waterflow time series in the overwhelming majority of cases.
It has been established that for rivers located in the middle part of Yakutia, a change in the behavior of long-term waterflow variations, which is presumably associated with global warming, can manifest itself in two main forms: a) in some cases, extremely high annual waterflow against the background of the typical regime of long-term variations - 1-2 cases (for the period from 1987 to 2018) lasting 1-3 years; b) the onset of a relatively long (5 years or more) period with an increased annual water content against the background of a violated of the cyclical behavior of long-term water content variations, which is typical for a given river. Herewith, for the rivers of the western region zone, the absence of pronounced changes in the behavior of long-term waterflow variations has been detected.

Authors: Guzhel Yu A , Dotsenko S M , Kovaleva L A , Agafonov I V 
Published: March 2021

Abstract
Data found in literature suggests soybean seeds are superior to many oilseed crops if compared by the content of proteins, fats, phosphatides, and some other nutrients. No other floral or faunal product has such a combination of protein, fat, carbohydrates, minerals, and vitamins. This paper proposes using secondary soybean flour as germ, shell, or cotyledon flour in food production. Lack of solid evidence-based data on how this material is used in food design is indicative of the lack of research in the area, making this paper relevant. The article presents a process of making secondary soybean flour. It also describes the chemical composition and energy content of such flour as found by the researchers’ tests. The paper concludes with the newly formulated requirements to flour quality and safety.

Published: March 2021

Abstract
The Kirchenovskoye gold-silver deposit is one of the fairly large deposits in the Olovyanninsky region. In addition to rich ore mineralization, the distribution of noble metals in the host rocks is of interest. For five selected rocks, the contents of noble metals (Rh, Pd, Ag, Pt, Au) were determined, the main part of which is represented by metasomatites: beresitized granite, graphite metasomatite (gneiss), graphite shale, mudstone and rocks from the weathering crust. For this, the method of mass spectrometry with inductively coupled plasma (ICP MS) was used. Promising mineralization for Au, Ag, and Pd (mudstone, graphite shales and gneisses) have been identified. The concentration of noble metals in ores and host rocks occurred due to the removal of these metals from the granitoid massif by hydrothermal solutions.
Dynamics of Biogens to Estimate Ecological State of Coastal Waters of Southern Baikal
Authors: Afonina T E 
Published: March 2021

Abstract
The issue of biogenic pollution of the coastal waters of Lake Baikal has been considered, an inventory of their sources performed, and an ecological estimation of the coast anthropogenic pollution factors given, which, in turn, indicate the increased content of biogens in coastal waters and, according to scholars, affect the growth of spirogyra (Spirogyra Link and Stigeoclonium Ktz).
The studies performed have covered the southern coast of Lake Baikal from Kultuk Bay to Novosnezhnaya settlement since it is the most populated area with developed infrastructure, and the alluvial-accumulative coast has excellent beaches and good access roads to them. To estimate the biogen ingress, studies have been performed in the summer months (navigation season) and in March (ice period). The actual research results are represented in tabular and graphic material.
The own research results have shown that the biogen content is rather significant; it is high during the ice period. The intake of domestic wastewater is supported by the high content of biogens in samples taken at the water’s edge also during the ice period. In summer, the biogen content in coastal waters may be higher than in the ice period, however, due to the navigation season currents, their concentrations are ‘washed out’.

Abstract
The paper presents a method to preserve high conservation value forests in accordance with the international certification system of the Forest Stewardship Council (FSC) in the Prichulym taiga of Tomsk region during logging. The taiga landscapes in the area of Prichulym’e are unique due to natural monuments, reserves, and specially protected natural areas with rare species of animals, birds, plants and valuable coniferous stands. These territories included in the forest fund of Tomsk region demand increased attention and systematic control, especially during logging and timber harvesting. At the first stage of the study, forest areas in the operational forests of the Zyryanskiy forestry in Tomsk region, leased by Sibirles OOO for logging and timber harvesting, were investigated. Based on the results of the study, some forest areas were referred to the category of high conservation value forests in accordance with the above-mentioned voluntary international certification system that implies an important function of protecting habitats of rare and endangered species of animals and plants, including those listed in the Red Book and regionally significant species. In such forests, logging and any type of felling are prohibited. Thus, these areas were conditionally excluded from the list of forests allowed for final felling. The results of the independent monitoring performed by the authors allowed the following conclusion: no violations were found in logging activities of Sibirles OOO that leased the parts of the forest in Zyryanskiy district for logging and timber harvesting. On the one hand, such joint activities and monitoring are economically costly; on the other hand, they are important and significant for further identification of the places abundant in unique flora and fauna.
The Possibility of Using the Existing Large-Sized Equipment of the Units when Switching to New Oil Treatment Technologies
Authors: Ivanyakov S V , Kryuchkov D A , Pechnikov A S 
Published: March 2021

Abstract
Oil treatment at field stabilization units allows preparing oil for storage and transportation, including by reducing the RVP and hydrogen sulfide content in oil. However, the use of direct fire heating of oil in pipe stills to maintain the thermal regime in the stabilization column may cause the formation of secondary hydrogen sulfide as a result of the thermal decomposition of heavy sulfur-containing hydrocarbons, which leads to additional financial losses for bringing the stabilized oil to the requirements of the current regulatory documents. A way to reduce the amount of secondary hydrogen sulfide is the transition from direct fire heating of oil to heating through an intermediate high-temperature coolant. In this case, the thermal regime of the stabilization column operation is maintained by heating in the reboiler, while it remains possible to use the existing unit columns and stills without their significant retrofitting.
Digital Forecast Technologies for Sustainable Agriculture: Optimization of Fungicidal Treatments of Potato for the Far East Region

Published: March 2021

Abstract
Far East represents the zone of risk farming that limits the productivity of potato significantly suffering from the late blight epiphytoties. Modern digital technologies can help farmers to overcome this problem. Using the VNIIFBlight Decision Support System (DSS) and archived data (2004–2018) from eight weather stations of the Khabarovsk Territory, we zoned this region in relation to potential potato yield losses associated with the late blight outbreak risk and calculated average frequencies of seasons with high, moderate, and low risks for each observation point. For each season and point, DSS determined dates of possible reinfection and the optimal dates of fungicidal treatments providing efficient protection. Comparison of the DSS-recommended scheme with the routine approach (regular treatments every 8 days) showed that DSS provided 1.9, 2.2, and 5× reduction of the number of treatments for seasons with potential yield losses >20, 10–20, and <10%, respectively. To provide farmers with the access to information required for decision-making, a “Geosystem” GIS was developed as a part of the meteorological service of the Infometeoservice company (http://infometeos.com/Map/Data). The GIS works in a real-time mode indicating the risk of the late blight outbreak at the points of interest that is important for the final decision concerning crop protection activities.

Published: March 2021

Abstract
The growing planet population requires manufacturing more products to replete nutritional deficiency, including those enriched with amino acids to maintain the balance of nutrients in the human body. Pate is an option of an alternative energy-dense meat product, ready-to-eat from a container by plastering on a bakery product as is or using as a side dish for the main course. A pate enriched with BCAAs, microbial proteinase, and goose liver conferring flavor and stabilizing the product has been developed. A solution has been proposed for ensuring food safety through identifying goods using a QR code, in which data on the type of feed, breeding meat cattle on farms, transportation, meat processing plant, meat product processing, and storage until the sale at a retail outlet to the end consumer are encrypted in a table format. The proposed measures contribute to the trust relations between the seller and the consumer and convenient delivery of information to the executive authorities, which will allow obtaining complete information on the goods purchased through the retail network with the supply chain.
Models of Signals of Eddy-Current Transducers above Defects of the Continuity of Metal
Authors: Zagidulin R V , Zagidulin T R , Bakiev T A , Bakiev A T 
Published: March 2021

Abstract
The shape of real signals of eddy-current transducers of electromagnetic flaw detectors obtained over continuity defects in the process of monitoring the surface of steel products and metal structures depends both on the type of eddy-current transducer and on the type of continuity defects in the metal (single defects, a group of cracks, pitting corrosion). When solving practical problems of eddy-current flaw detection of steel products and metal structures, there is a need for mathematical modeling of the measured signals of eddy-current transducers of different types (absolute, differential, overhead, throughput) over continuity defects in the metal.
Signal models of eddy-current transducers are also important from a methodological point of view, since they allow one to study the transformation of the eddy-current transducer signal shape with an arbitrary change in the parameters of real continuity defects in the metal, which facilitates the analysis and interpretation of flaw detection results.
It is shown that the signal waveform of an overhead eddy-current transducer of an electromagnetic flaw detector above a continuity defect is determined by its type, while for an absolute overhead eddy-current transducer it has a unipolar character, the extremum of which is located above the center of the continuity defect; for a differential overhead eddy-current transducer, it has a bipolar character, the extremes of which are located symmetrically on opposite sides of the center of the continuity defect.
To describe the signal waveform of the indicated types of overhead eddy-current transducers, mathematical models based on simple algebraic functions have been proposed that have two tuning parameters.
It is shown that these tuning parameters are related to the amplitude and half-width of the measured signal for the absolute overhead eddy-current transducer, and with the distance between the extremes for the measured signal of the differential overhead eddy-current transducer over the continuity defects such as a crack in the metal.
On the basis of these functions, mathematical models of signals of overhead eddy-current transducers above a group of cracks are proposed. It is shown that a change in the interval between continuity defects and their number in a group of cracks leads to a significant transformation of the signal waveshape of the overhead eddy-current transducers.

Published: March 2021

Abstract
In this paper there have been analyzed problems of biodiversity conservation in the Altai Republic in the context of economic development of the territory. The main types of economic activities have a different impact on the biodiversity of the region. The authorities and environmental services take measures to preserve the natural environment, flora and fauna, including the organization of specially protected natural areas, the study of biodiversity and the publication of regional Red Data Books, the elaboration of projects for the artificial cultivation and breeding of certain species of plants and animals, including the Red Data Book ones. It has been shown that the problem of preserving medicinal plants included in the Red Data Book of the Altai Republic has been unsolved for more than 20 years. This can lead to the almost complete disappearance of these species outside the borderlines of specially protected natural areas of the federal level.

Authors: Titov D Yu , Titov E Yu , Bordikov I V 
Published: March 2021

Abstract
The influence of the energy of low-voltage discharges in the liquid phase on the directions of fragmentation of toluene is studied. The discharges were generated by a 60 V DC source with a capacitor of 90 μF, 20090 μF, and 40090 μF. Fragmentation of toluene leads to the formation of carbon structures on the surface of graphite electrodes and in a liquid medium. It was revealed that an increase in the power of electric discharges leads to the growth of carbon structures on the surface of electrodes, reduces the output of the gas phase and finely dispersed carbon structures. The morphology and composition of solid phase products were determined by scanning electron microscopy and energy dispersive X-ray spectroscopy. Nanosized carbon structures are obtained in the form of aggregates - carbon nanohorns, which actively adsorb oxygen (content 0.9-3.6 at%). The composition of gaseous products was determined by gas chromatography. It was revealed that with an increase in the power of electric discharges, the hydrogen content slightly increases from 74.8 to 75.15 mol%, methane from 5.86 to 6.55 mol%, neopentane from 0.02 to 0.55 mol%. At the same time, the acetylene content in gaseous products decreases from 18.14 to 16.36 mol%.

Abstract
The article is devoted to the actual problem of construction and operation of pipelines in difficult geological conditions. The paper analyzes the interaction of permafrost soils with underground structures. One of the main problems is considered the soil heaving - the ability of water-saturated soils to increase its volume when frozen. The authors analyzed one of the existing calculation methods for determining the stress-strain state of a pipeline laid on heaving soils; the dependences of the determination of the normal forces of frost heaving have been investigated; calculated the values of stresses and displacements in the SCAD software package. It was revealed that the problems associated with the phenomenon of changes in the volume of soils with temperature drops depend both on the rate of soil freezing and on the length of the heaving section.

Abstract
The Russian Federation and China participate and cooperate in various natural challenges, fighting these confrontations. Russia, China’s largest neighbour, in response to an outbreak of coronavirus, suggested that it join forces in the fight against a new virus. This is a step in deepening the economic, humanitarian, scientific and technical cooperation of the Russian Federation and China. In addition, the largest economies of the world participate in the Paris Climate Agreement (EU, USA, PRC, RF and other countries). This will allow developing many international projects. The Chinese initiative “One Belt, One Way”, including in addition to the Russian initiative “Ice Silk Road”, can become particularly effective “green and smart”. Compensation for carbon dioxide emissions - the creation and supply of environmentally friendly equipment, the development of agricultural and forestry joint Russian-Chinese investment-production and foreign trade, customs enterprises and projects, including free economic zones. China is investing environmental attention in the Russian Federation: energy, agriculture, forestry, environmental equipment, including for the gas industry, including LNG equipment for Russian enterprises. Russian-Chinese relations are characterized by high development dynamics, mutual understanding, and a solid legal base.
