Abstract
Increasing crop yields is the most important condition for intensifying agricultural production. High quality of various technological operations of soil preparation can significantly increase yields. It is especially important to prepare soil before seeding, it forms a habitat for plants, ensures uniform seeding in depth. Using heavy machines in agriculture, surface and subsurface soil layers undergo mechanical deformation with inevitable deterioration of its physical and biological properties. Density of surface and subsurface horizons increases, number of pores with a size of 0.2 … 10 microns decreases, which determine soil moisture content. Productivity of cultivated plants is influenced by effective fertility of not only surface layer, but also machines and tractors. Many studies have established that soil deformation during movement of cultivator hoe or wedge consists of two stages. At the first stage, soil particles located in close proximity to the hoe are displaced forward, forcing the layers in front to compress, when stresses in soil reach their limit values, a shift occurs at some distance from the toe of the hoe. At the second stage, soil begins to intensively move forward and upward and move along surface of working body. In this regard, resistance of soil to movement of individual parts of working body will be different. The article describes research that helps to determine ground unevenness. One of the possible measures to prevent compaction of the subsurface is presented - improving technology of preparing upper surface soil layer.

Published: September 2021

Abstract
Analysis of various approaches to optimizing the trajectories of agricultural machinery across the field made it possible to determine the main points that have reserves for optimization. Algorithms were obtained to optimize tracks at this stage of research, on fields with small slopes. The construction of tracks is implemented in software both for a given entry point and direction of movement, as well as a choice of entry points and directions that optimize the time and fuel costs. Variants of building tracks for vehicles with different grip widths, as well as for cases of movement of several pieces of equipment in various kinds of combined versions, have been implemented. The software implementation was carried out using the JAVA 8 and GeoTools 19 technology stack.
Application of techniques for moving dynamics series for planning and forecasting indicators in agrotourism
Authors: Vasilieva E A , Zatylkov N I 
Published: September 2021

Abstract
Planning and forecasting in agrotourism have their own characteristics, due to the specifics of the industry, associated with the finding of this area in close connection with agriculture and tourism. At the same time, in the planning of agricultural indicators, it is necessary to adhere to long-tested and positively proven methods based on quantitative methods. The qualitative side of agrotourism implies the need for a separate approach to planning a number of indicators, such as the price of a service. Forecasting methods here should take into account the purely market orientation of the tourist component. In addition, the field of agrotourism is mostly represented by small farms, which most often do not use professional software products for the purpose of forecasting indicators and further planning their activities on this basis. This article describes the methods of moving the dynamics series for planning and forecasting indicators in agrotourism.

Published: September 2021

Abstract
At the present stage of economic development in a market economy, the most urgent problem is the rational using the economic potential of the regions to meet the needs of the population in food, as well as other goods and services. The implementation of the food program should be carried out not only through the growth of agricultural production, the efficient operation of food and processing enterprises, the expansion of personal subsidiary farms, but also through the using other sources of food resources, in particular, for example forest products. The severity of this problem is determined by the huge scale of the Russian economy, on the one hand, and the constant increase in prices for food raw materials, on the other.

Published: September 2021

Abstract
The specifics of the current state of the meat market in China are largely determined, like the vast majority of production-consumption relationships in global socio-economic processes, by the current organizational constraints aimed at preventing the spread of the COVID-19 disease. Thus, the Ministry of Transport of the People’s Republic of China has developed specific guidelines to prevent the spread of the pandemic through the transportation of meat products, At the same time, the economic and organizational mechanism of the State Council of the Republic, aimed at ensuring the prevention and expansion of pandemic control provides for the implementation of a plan of full chain, closed, tracked regulated imported food products. A negative aspect of the implementation of the said mechanism is the increased threat of disruptions in meat supply with the potential for higher prices for imported pork.
The impact of climate change on regional food security
Authors: Fedotova G V , Vertakova Yu V , Klevtsova M G 
Published: September 2021

Abstract
Climate change has serious consequences for agriculture and food security, creating new risks and challenges and exacerbating existing local to global vulnerabilities. Climate change can affect all aspects of the food security of vulnerable groups, as well as various elements of food systems. Climate transformation and food security are two challenges that need to be addressed together. The aim of this research is to study the impact of climate change on regional food security. In the course of the research, the following methods were used: structural and logical analysis, monographic analysis, methods of statistical grouping. As a result of the study, using the example of the Southern and Central Federal Districts, the authors have analyzed the dynamics of various indicators of the state of natural conditions and the actions of regional government structures, which reflect individual elements of maintaining food security. The proposed methodological approach to assessing the impact of climate change on regional food security is distinguished by the use of private indicators for diagnosing the level of food security. The system of these indicators includes both the study of natural conditions and the level of ecological safety of the region. The use of the proposed tools for measuring the impact of climate change on regional food security will increase the effectiveness of the actions of regional government structures, which reflect individual elements of maintaining food security.

Published: September 2021

Abstract
The article is devoted to improving the methodological tools for assessing food security threats to the constituent entities of the Russian Federation, taking into account the territorial specifics (for example, the Arctic regions). The need for a food security assessment procedure in the context of two approaches is indicated: 1) an assessment of the food security of the Arctic zone, as a set of territories of several regions belonging to different federal districts, but united by a single legal status; 2) an assessment of the food security of the Arctic zone, as a part of the constituent entity of the Russian Federation, the territories of which are fully or partially referred to the "Arctic" status. As a result of the comparative analysis of approaches to assessing food security in foreign and domestic practice, a system of indicators was formed, differentiated into 6 projections (criteria): physical availability of food; economic affordability of food; sufficiency of food consumption; food quality; transport accessibility; support for the functioning and development of the agro-industrial complex. Approbation of the proposed assessment toolkit was carried out on the example of the regions of the Arctic zone of the Russian Federation, the studied period is from 2012 to 2019. As a result of the assessment, food security threats have been identified both in the context of a separate Arctic entity and the Russian Arctic as a whole. The identified threats provide a basis for the development of specialized tools aimed at improving the regional economic policy in the food sector, taking into account the territorial specifics, as well as increasing the level of food security in the Arctic zone of the Russian Federation.

Published: September 2021

Abstract
The objective is to obtain calculation and analytical mathematical models of the abundance of mosquitoes depending on the following factors: average monthly temperature over the year, average monthly precipitation over the year and average monthly atmospheric pressure over the year. The obtained models show the individual effect of each factor and their combined effect. The population of mosquitoes is most dependent on the average monthly precipitation. Its influence is 3.5 times greater than that of the average monthly temperature, and 6.4 times greater than that of the average atmospheric pressure. Also, models were obtained to enable calculation of the population size of mosquitoes without resorting to expensive field survey.

Published: September 2021

Abstract
Biodiversity conservation is the creation of the necessary conditions for the preservation and restoration of the natural set of species of living organisms within certain landscapes and ecosystems through full compliance with established environmental standards and norms when using various components of the natural environment in various spheres of the economy and production. This is a key factor in ensuring the necessary availability of biological resources in conditions of a complicated ecological situation with irrational use of natural resources and non-observance of natural ecological conditions for the preservation and life of various living organisms. For this purpose, it is necessary to form a system of "green" economy, built on the repeated use of components of the natural environment and the use of biological resources in accordance with the natural regime of their restoration.

Authors: Goncharova A V , Sotnikova L F , Kostylev V A , Stekolnikov A A 
Published: September 2021

Abstract
Among the large number of eye diseases in horses, the largest percentage is occupied by keratopathies, accompanied by damage to one or more layers of the cornea. Keratopathies are multifactorial diseases that occur in one case with traumatization of the cornea and further development of the disease – primary, in the other case with the accumulation of toxins, antigens, and under – oxidized products in the tear fluid-secondary. The absence in the modern literature of the hypothesis of the pathogenesis of keratopathies, summarizing the data accumulated to date, makes it difficult to develop further promising directions in the study of these complex diseases.
Vegetation changes in the chemical composition of Rosa acicularis
Authors: Shanina E V 
Published: September 2021

Abstract
In the modern world consumers’ attention is attracted by wholesome, safe and ecologically-friendly food products that can be qualified as "natural". In this regard, wild plants growing in the region seem worth to be involved in processing. Rosaacicularis Lindl is of particular interest as a promising non-traditional medicinal and technical raw material. To assess its quality and use in products recovery, comprehensive information on both the chemical composition of fruits and plant biomass is required. This paper studies the dynamics of biologically active substances transformations in the Rosa acicularis biomass during the growing season. The change in the mechanical composition of the vegetative part of Rosa acicularis in the spring-autumn period is presented. The change in the content of vitamins, organic acids, pectin and tannins, pigments in shoots, leaves, roots and fruits of a plant during the growing season is considered. From May to June - July most biologically active substances are accumulated in the vegetative parts of Rosa acicularis. In fruits the maximum content of biologically active substances falls on August - September. This fact allows recommending not only fruits, but also the vegetative part of the plant for industrial processing.
Causal diagram with positive and negative feedbacks of the grain molasses production process
Authors: Bulatov S Yu , Semenov S V , Krupin A E , Shkilev N P 
Published: September 2021

Abstract
The development and improvement of unique technologies for the production of feed and feed additives is currently an urgent problem, which is formulated at the level of the Government of the Russian Federation. Such technologies include the production of grain molasses in the conditions of agricultural enterprises from raw materials of their own production. To date, the technology for producing molasses from grain has been developed, but there are very few technical means for its implementation. The question of the operation of such installations remains insufficiently disclosed both from a scientific point of view and from a technical point of view, and requires further research. The paper substantiates the design of the plant for the preparation of molasses from grain on the basis of a mental model. When developing the mental model, the installation was considered as a "black box". For maximum consideration of all factors, a mental model of the pumping unit in dynamics is formed. A cause-and-effect diagram with positive and negative feedback on the selection of the pump for installation is formed. The diagram consists of variables and relationships between them with positive or negative effects. It is revealed that the key elements of the diagram are the electric pump and the dispersant, which provide the movement of the suspension. However, the dispersant is more complex, more expensive to manufacture, and has a lower performance compared to an electric pump. Therefore, it follows from the mental scheme that it is possible to achieve an increase in the productivity of the plant due to its technical improvement, taking into account the demand for molasses and focusing on the company’s profit from the use of this plant.

Published: September 2021

Abstract
The work considered the development of technology for cultivating new hybrids of spring rapeseed breeding by LLC Jerman Sid Alliance Russ RAPOOL in the natural and climatic conditions of Eastern Siberia. The research was carried out in the production experience of grain-and-grains crop rotation at the field station of the ERPC "Borsky" in the conditions of the Krasnoyarsk forest-steppe. Six new spring rapeseed hybrids of RAPOOL’s Clearfild ® breeding system were studied, advanced cultivation technology and a system for protecting the crop from harmful organisms were tested, biological and actual yields were assessed, and the main elements of the crop structure were determined. The seed oil grain of spring rapeseed hybrids in full protection versions was well made with almost the same weight of 1000 seeds and ranged from 4.0 to 4.5 g. An assessment of the biological yield from the main alimony of the crop structure shows that it varies by hybrids and varies from 3.3 t/ha in the Lagonda hybrid under control to 7.03 t/ha in the Drago hybrid with complete protection. The same assessment on Clearfild ® spring rapeseed hybrids showed a high biological yield, which varies from 5.6 t/ha in the Cyclus hybrid to 7.8 t/ha in the Chip CL hybrid. High harvest yields were formed by Contra CL and Chip CL hybrids, 9.5 and 9.4 t/ha, respectively. The highest actual seed yield with full protection was shown by the Drago hybrid (6.2 t/ha) and Chip CL hybrid (7.2 t/ha). The assessment of spring rapeseed hybrids from the Clearfild ® system group showed that their actual yield of oilseeds did not exceed the same in the first test using non-cryafield seeds.)

Published: September 2021

Abstract
At different periods of swelling and incubation (12, 24, 36, 48, 60 h) soybean seeds were selected: swollen (after reaching the critical humidity of soy 58.6 %; rapeseed 43.6 %); sprouted "spouts"; with sprouts ≥1 cm. It was found that the protein content in seedlings gradually decreases from 37.0-41.3% in dormant seeds, to 18.6-20.3% in sprouts after 48 hours in rapeseed and 60 hours of incubation in soybeans. The developed method of differentiation of germinating seeds by physiological state made it possible to register step-by-step changes in extracts according to pH and buffer capacity (BC). This rapid analysis is applicable in the development of technology for protein complex extraction and preparation of protein preparations from non-traditional sources.

Published: September 2021

Abstract
The article describes the cold imprinting modifying effect on the adrenomedullary cells functional state in adult animals. It has been shown that short-term cold exposure in early ontogenesis leads to an increase in norepinephrine reserves in the adult rats’ adrenal glands. With these animals test cooling, the phenylethanolamine-N-methyltransferase activity in the adrenal glands decreases, thereby preserving the hormone reserves, which is the thermogenesis dominant activator in the mammalian body.

Breed as a biotechnological phenomenon
Authors: Lebedev I G , Pimenov N V , Lomskov M A , Ivannikova R F 
Published: September 2021

Abstract
Authors of this article discuss about the problem of developing the theoretical foundations of animal domestication (including the creation of breeds) in modern biological science. Unfortunately, at the moment, the issue under consideration, which is located at the intersection of such scientific disciplines as zoology, biotechnology, veterinary medicine and animal science, in the Russian Federation is insufficiently studied and generalized theoretically. In addition, the analysis of the use and interpretation of the term «breed» is carried out on the example of the current situation in Russian agriculture. The processes of creating and using breed standards are also considered. Our own experience demonstrates that the creation of a reasoned and complex teaching about the breed as a biological and technological phenomenon will significantly improve the quality of veterinary and zootechnical education and fundamental biological science.
Balanced Functional Module Detection in genomic data
Authors: Tritchler David , Towle-Miller Lorin M , Miecznikowski Jeffrey C 
Published: September 2021

AbstractMotivationHigh-dimensional genomic data can be analyzed to understand the effects of variables on a target variable such as a clinical outcome. For understanding the underlying biological mechanism affecting the target, it is important to discover the complete set of relevant variables. Thus variable selection is a primary goal, which differs from a prediction criterion. Of special interest are functional modules, cooperating sets of variables affecting the target which can be characterized by a graph. In applications such as social networks, the concept of balance in undirected signed graphs characterizes the consistency of associations within the network. This property requires that the module variables have a joint effect on the target outcome with no internal conflict, an efficiency that may be applied to biological networks.ResultsIn this paper, we model genomic variables in signed undirected graphs for applications where the set of predictor variables influences an outcome. Consequences of the balance property are exploited to implement a new module discovery algorithm, balanced Functional Module Detection (bFMD), which selects a subset of variables from high-dimensional data that compose a balanced functional module. Our bFMD algorithm performed favorably in simulations as compared to other module detection methods. Additionally, bFMD detected interpretable results in an application using RNA-seq data obtained from subjects with Uterine Corpus Endometrial Carcinoma using the percentage of tumor invasion as the outcome of interest. The variables selected by bFMD have improved interpretability due to the logical consistency afforded by the balance property.Supplementary informationSupplementary data are available at Bioinformatics Advances online.

AbstractThe long and challenging drug development process begins with discovery biology for the selection of an appropriate target for a specific indication. Target is a broad term that can be applied to a range of biological entities such as proteins, genes, and ribonucleic acids (RNAs). Although there are numerous databases available for mining biological entities, publicly available searchable, downloadable databases to aid in target selection for a specific disease or indication (e.g., developing contraceptives and infertility treatments) are limited. We report the development of the Contraceptive and Infertility Target DataBase (https://www.citdbase.org), which provides investigators an interface to mine existing transcriptomic and proteomic resources to identify high-quality contraceptive/infertility targets. The development of similar databases is applicable to the identification of targets for other diseases and conditions.
