Authors: Osipova I M , Naumova T A 
Published: January 2020

Abstract
In the article, digitalization is considered as the result of the efficient use of labor resources. In turn, for the full use of labor capital, it is necessary to create a certain level of people’s quality of life. Therefore, on the example of the Irkutsk region - a subject of the Russian Federation, a relationship was made between these characteristics. The level of quality of life was analyzed for five groups of indicators and each was compared with a growth rate of costs for information and communication technologies, which presumably indicates the level of access to ICT. The main directions for the sustainable development of digital technologies in the region are noted

Published: January 2020

Abstract
Ultrasound drying experiments of wicking and foam materials, spicy herbs in particular, with improved quality characteristics were carried out with sufficient efficiency of the created plant based on the steam convection oven. It was shown that drying optimization process can be preliminarily calculated using a theoretical model of ultrasonic exposure together with the supply of a heated drying agent to a temperature significantly lower than that accepted in industry (no more than 50-55 °C). Consequently, the drying time was reduced 2, as well as energy consumption level demonstrated 30% decrease.

Authors: Kostarev S N , Sereda T G , Kochetova O V , Sidorova K A 
Published: January 2020

Abstract
The features of the technological process of silage formation are described. A kinetic model of biochemical reactions in the preparation of silage juice was developed and investigated. The kinetic model was the ratio of the growth rate of the silage mass under the influence of a complex of factors on it: specific growth rate, concentration of microorganisms, the use of various additives. The models of emission processes occurring with the synthesis of methane and carbon dioxide are studied. A system of automated monitoring and control of the technological process of silage has been developed. The accounting and monitoring of greenhouse gases generated during silage decomposition is also an important environmental challenge. The design of silage trenches included calculations of the bearing capacity of the base and the stability of clay slopes. For the computer-aided design system, the AutoLISP software module of the AutoCAD environment was used. The developed computer-aided design system allows speeding up the construction of outline drawings with various geometric parameters of the silage trench.

Abstract
The North Siberian plain is the main fawning ground and summer feeding of wild reindeer of the Taimyr tundra population. After an explosive increase in numbers in 2000, when the population increased to 1 million of individuals, there is a decrease in the deer number. According to aerial surveys in 2017, it amounted to 404-442 thousand of individuals, in 2019, according to research staff members of the Taimyr Nature Reserves, it decreased to 250-280 thousand. Based on mathematical modeling and analysis of information obtained when marking 17 deer with collars with satellite transmitters, the paper considers version of the population response to environmental factors. Against the background of tundra “greening”, the growth of plant biomass, the length of deer stay in Taimyr did not increase, but, on the contrary, it decreased almost three times and averages 63 days in comparison with the 1960s. The questions solved in this paper consider the reasons why deer leave their former feeding grounds in the middle, or even at the beginning of August and if a significant reduction in the volume of deer hunting will lead to a completely opposite effect.
Dual effects of medicinal plant extracts on mature biofilms of Escherichia coli dependent on time of exposure
Authors: Samoilova Z Y , Smirnova G V , Oktyabrsky O N 
Published: January 2020

Abstract
Using a relatively simple experimental model with mature biofilms of Escherichia coli we showed that 1 h incubation with Vaccinium vitis-ideae, Betula pendula and Laminaria japonica extracts promoted biofilm dispersion inducing oxidative stress in the biofilms. However, a prolonged 3 h treatment completely changed mode of action of these extracts to strong prebiotic effects which were related to intracellular iron chelation.
Scientific framework for selecting explants of Iris L. genus for direct shoot regeneration
Authors: Tikhomirova L I 
Published: January 2020

Abstract
The explant type, its anatomical structure, and hormonal composition of culture media are crucial for selecting explants of Iris L. genus for direct shoot regeneration in tissue culture. In case of vegetative bud culture, antibiotics must be added to the agar medium with due regard to the antibiotic sensitivity of microflora. On MS medium (Murashige and Skoog 1962) supplemented with BA (6 µM) + NAA (5 µM) + L-glutamine and adenine sulfate (100 mg/l), the embryos of I. hybrida and I. sibirica developed into adventitious shoots and the multiplication coefficient of I. ensata increased in subsequent passages. In the budding phase, the rhachis and perianth tube maintained meristematic tissues and exhibited morphogenetic capacity. The fragments of generative organs of I. ensata, I. hybrid and I. sibirica formed the shoots on MS media containing BA (4–8 µM) and NAA (3–5 µM). The highest percentage of the shoots (100%) formed from the perianth tube explants had the structure similar to perianth lobes instead of the first leaf primordia. Further culture resulted in the formation of the shoots typical of these species of iris.

Published: January 2020

Abstract
This work presents the results of the use of maceration and ultrasonic extraction for the isolation of antioxidant substances, particularly flavonoids, from the Polygonum Weyrichii Fr. Schmidt growing in the Murmansk region. This plant is characterized by a high content of flavonoids and other antioxidant substances, and therefore may be of interest as a potential source of natural antioxidants. The efficiency of extracting flavonoids from various parts of plants (inflorescences and leaves) by maceration for 24 hours in 70% ethanol and using ultrasonic extraction for 1-5 hours at a temperature of 50 °C is compared. Antioxidant activity was evaluated for all extracts using the phosphomolybdate method. It was found that the maximum extraction of flavonoids is achieved by using ultrasonic extraction for 2 to 4 hours.

Authors: Trefilov R A , Dorodov P V , Kasatkin V V , Kasatkina N Y , Litvinyuk A A 
Published: January 2020

Abstract
The paper presents a computational method that allows to predict the process of drainage of flax seeds with expanded perlite and biohumus for complex pre-sowing treatment with preliminary irradiation of seeds in the infrared range. From a methodological point of view, in the process of seed granulation, the efficiency depends on the adhesive bond arising in the process of rolling and dispersing. To solve this problem, the calculations of mathematical models of the process of granulation of seeds and the process of dispersion of perlite with biohumus on the surface of seeds were carried out in order to obtain a finished dragee with components of natural origin and improve the sowing qualities of treated seeds and the finished product. As a result of the developed models, analytical solutions of kinetic problems for the process of precipitation of particles of a draining mixture of perlite and biohumus on the surface of flax seeds are obtained. The described mathematical model allows to determine the technological parameters of the granulation process-particle size of the granulating mixture and granulation time, for the calculation of granulating components in the development of technological equipment for granulation. The approximation of the obtained data was made, which showed the prospects and effectiveness of the ongoing developments.

Published: January 2020

Abstract
The research is devoted to the use of a cod skin hydrolysate as a component of citrus fruit beverages. It is demonstrated that the addition of a hydrolysate increases the content of protein in the beverage, slightly increases the viscosity of the beverage, and does not adversely affect its sensory characteristics. Hydrolysate is produced by enzymatic treatment of cod skin. The processing parameters allowing achieving the desired degree of destruction are determined. Physico-chemical parameters and sensory analyses of the obtained hydrolysate and its amino acid composition were analyzed. The influence of collagen hydrolysate on the physical and chemical composition of beverages, their structural and mechanical characteristics (pH and viscosity) and sensory analyses are estimated.

Comparison of granular and open cell foam filter models by numerical simulation
Authors: Soloveva O V 
Published: January 2020

Abstract
A comparison of granular and highly porous mesh filter models is based on the results of numerical simulation. We created models filters with an equal diameter of granules and cells. In order to avoid calculation errors associated with a random arrangement of cells, we averaged the results for five geometries. The values of the pressure drop obtained based on numerical simulation correlate well with the data obtained by the experimental Ergun equation. We calculated particle deposition efficiency and filter quality factor for models with equal porosity, and pressure drop value. Additionally, the filter quality factor for geometries with equal particle deposition efficiency was estimated. The calculation results show that it is advisable to compare the filter models by the value of the differential pressure.
Issue of agricultural lands exhaustion and land use planning and methodological approaches as solutions to this problem
Authors: Meretsky V A , Zhigulina T N , Kiseleva A O 
Published: January 2020

Abstract
The article considers one of the priority issues of global land management and land resources management – agricultural lands exhaustion. It was revealed that agricultural lands exhaustion processes are caused by the absence of a number of organizational and economic mechanism elements in land management, in terms of control over the quality condition and land fertility. In order to improve the agricultural land management system, there was proposed a mechanism composed of a combination of legal, land management and agroecological measures. The central element of the organizational and economic mechanism for monitoring the processes of agricultural lands exhaustion is the proposed methodological approach of assessing the level of agricultural lands exhaustion and subsequent estimation of monetary value of the economic damage caused by the identified processes of agricultural lands exhaustion. Economic calculations of the cost for soil fertility factors restoration up to their optimal parameters are composed of calculation of differential rent values in terms of fertility and location of the investigated and reference soil being capitalized taking into account the standard period of capitalization in agriculture. The monetary value of the economic damage caused by the identified processes of agricultural lands exhaustion is determined as the difference between the values of capitalized rent for the investigated and reference soil.

Published: January 2020

Abstract
The work is devoted to the actual problem of optimizing the control of complex chemical-technological processes of structuring multicomponent elastomeric composites. Optimization of production processes improves the quality of the products obtained, contributes to their intensification, as well as reducing the formation of defect. The article discusses the optimization of the process of structuring multicomponent elastomeric composites based on physicochemical representations and kinetic mathematical models. The basic relationships between model parameters and quantitative characteristics of the process of structuring elastomeric composites are given. It is shown that, along with the main characteristics of the structuring process, it is advisable to use new quantitative estimates - the amplitude and mode of the velocity curve. An optimization criterion is formulated - increasing the economic efficiency of production of products from elastomeric materials by increasing the percentage of obtaining high-quality products from raw materials while minimizing defect.

Authors: Antipova E M , Antipova S V 
Published: January 2020

Abstract
The aim of this work is to identify the features of the synanthropic component of the flora of Sosnovoborsk, a satellite town of the regional center of Krasnoyarsk (Krasnoyarsk region). Based on the study of 7 model sections within the administrative boundaries of Sosnovoborsk, which differ in the phytocenotic diversity of the landscape and the characteristics of the anthropogenic load, the composition and structure of the synanthropic fraction of the flora: the share of apophytes and advents, hemerophiles and hemerophobes, synanthropic groups of species according to the degree of naturalization and certain activity criteria, were chosen. It was established that there was a prevalence of apophytes in the city flora (92%), where 54.2% of the total number of apophytes there were hemerophiles, which is generally typical of urban floras. Among minor advents (8.0%), colonophytes dominate (54.8% of the advent fraction). The basis of the synanthropic fraction of the flora of Sosnovoborsk (57.9% of the total flora) is rural species (according to I. Hensky) - 45.5%, consisting only of apophytes and found in all model sections of the city. At the present stage, a change in the floristic composition of Sosnovoborsk is due to urban-philic species (54.2%). The low adventization index (0.08) arises from the predominance of colonophytes (54.8% of the adventitious fraction), as well as the content of adventitious species in the composition of small satellites (58.1% of the adventitious fraction) and citizens (41,9 %).

Researchers have found that the electromagnetic launcher with multipole track structure is capable of greatly improving the comprehensive performance of simple railgun. In this paper, a new quadrupole track electromagnetic launcher model is designed on the basis of simple railgun and quadrupole railgun. In order to fully analyze the electromagnetic characteristics of the model, the theoretical analysis of the structure is carried out at first. Then, under the same conditions as possible, the electromagnetic characteristics of it and the quadrupole railgun model are simulated and compared by using Ansys Maxwell simulation software. The results reveal that the new quadrupole track electromagnetic launcher model has the advantages of more concentrated magnetic field, more uniform armature current distribution and greater electromagnetic thrust.
Understanding of the Modeling Method in Additive Manufacturing
Authors: Chen Zhuojun 
Published: January 2020

Abstract
With the development of additive manufacturing, how to improve the efficiency and accuracy of manufacturing and prediction has attracted more and more attention. This paper focuses on three basic modeling methods, which are summarized according to the issue: empirical method, analytical method and numerical method. These methods are used differently based on practical circumstances. Besides, due to the improvement of computer computing power, machine learning and digital twin have also been applied to the study of additive manufacturing. Machine learning has a good performance in the prediction and optimization of process parameters, but the characteristic of machine learning that requires a lot of data leads to the increase of experimental cost. Digital twin does a good job in monitoring the condition of equipment. In addition, it can replace expensive and time-consuming physical experiments with inexpensive and efficient digital experiments, which can provide data for analysis. However, because of insufficient research, its application is still limited.
