Application of biogas in Russia
Authors: Simbirskikh E S 
Published: September 2020

AbstractBioenergy is the most promising type of renewable renewable energy (RRE) in Russia, which has a huge potential for using agricultural waste, wood processing, food processing, and urban treatment facilities. In turn, the most attractive segment of bioenergy for investors is the production of biogas, which can provide additional sources of income from the sale of organic fertilizers and fees for the safe disposal of organic waste. The main advantage of biogas energy in Russia in comparison with other types of RRE and traditional energy carriers is the availability of raw materials for the operation of the plant, respectively, the complete absence of fuel costs in the structure of operating expenses, since in 95% of cases, waste goes to the owner of the plant free of charge. Applying an integrated approach to projects with mandatory solutions to both energy and environmental problems will ensure an unprecedented growth of the biogas industry in the coming years.

Authors: Alejnikov A F , Cheshkova A F , Mineev V V 
Published: September 2020

Abstract
The application of the method of electrical impedance spectroscopy for the diagnosis of plant diseases is justified. Studies were carried out to identify the impedance parameters of strawberry leaf tissue associated with the effects of three pathogens of fungal diseases of garden strawberry, using the impedance analyzer WK 6505B. The analysis of variance of the mean values of the obtained data revealed that the most informative part of the changes in all parameters lies in the low-frequency region of the α-dispersion of bioimpedance. As the main informative parameter, it is proposed to use reactance measured at frequencies of 200 … 104 Hz, at which extremes of its change appear for healthy and diseased strawberry leaf blades.

Authors: Dorrer M G , Popov A A , Tolmacheva A E 
Published: September 2020

Abstract
The article proposes a solution for the implementation of the artificial vision of an agricultural robot (farmbot). The Yolo3 system in the Darknet topology was chosen as the software platform. Recognition of objects (strawberries) and their discrimination with other objects in the farmbot workspace is provided by a convolutional network of deep learning with the primary use of the neuron activation function ReLU. The architecture used made it possible to ensure a percentage of correct recognition of objects up to 92 - 93% during dynamic processing of the video stream, including when processing objects that have a significant external similarity with the target object - strawberries. Similar results suggest that the farmbot computer vision system built on the Yolo3 platform in the Darknet topology will be fully operational.

Published: September 2020

Abstract
Since a new Federal Law of the Russian Federation “On Electric Power Industry” has been adopted consumers with microgeneration systems can now sell excess electric energy. Consequently, more agricultural consumers got interested in using renewable energy installations. In this context, the study focuses on mathematical modeling of electricity output by a microgeneration system, in particular with PV panels, to assess the conceivable amount of electric energy that can be eventually sold. The authors built a model of the system tied to a grid for three options: fixed-tilt PV panels, PV panels with a solar tracking system, and concentrator PV systems. The findings analysis confirms that in order to maximize the electricity transmitted to the electric grid, it is rational to use solar energy concentrators with a Sun-tracking system.

Changes in birds’ demographic parameters of a key ornithological territory “Tract Trekhozerki” (Minusinsk basin) with fluctuations in water level
Authors: Zlotnikova T V , Geld T A 
Published: September 2020

Abstract
Today “Tract Trekhozerki” is a state natural zoological reserve of regional importance. The tract is home to over 100 species of birds, including 12 species listed in the Red Book of the Russian Federation. For five bird species, breeding information was obtained over the period from 2013 to 2018. In two species of gulls (Larus argentatus mongolicus Suskin, 1925 and Larus ichthyaetus), the abundance changes were similar: the number of breeding pairs decreased (in the second species to 0) from 2013 to 2015, and then there was an increase in numbers. The population of Ardea cinerea has decreased. Recurvirostra avosetta breeds irregularly in the tract, with 73 pairs nesting in 2018. For all these species, a decrease in the average size of masonry in years with a low water level was noted. Phalacrocorax carbo at nesting were noted only in 2013 and 2014. The changes in abundance are associated with cyclical fluctuations in the water level in water bodies: a decrease from 2013 to 2015 and a subsequent increase until 2018. This affected the availability of nests, the area of habitats suitable for nesting, and species competition. For species of birds listed in the Red Book of the Russian Federation (L. ichthyaetus and R. avosetta), the high, but not the maximum degree of watering observed in 2013 and 2018 is most favorable.

Published: September 2020

Abstract
The paper discusses the possibility of using a comprehensive treatment regimen for hepatosis in postpartum cows with the help of preparations with various mechanisms of hepatoprotective and anti-toxic effects. It was proved that enteral administration of Thionontrit-S against the background of intramuscular administration of Livazen to cows with clinical signs of hepatosis has a positive effect on the course of the disease and the recovery timing of animals. The use of a complex treatment regimen contributes to the manifestation of positive dynamics of the main hepatosis syndromes - hepatocellular insufficiency and impaired hepatocyte integrity, which is manifested by an increase in the level of total protein by 8.1%, albumin - by 20.9%, glucose - by 31.6%, triglycerides - by 21.4% and cholesterol - by 27.5% in comparison with the basic treatment. The use of Thionontrit-S as part of the complex treatment of bovine hepatosis made it possible to reduce the activity of the inflammatory process in the liver, which was manifested by a decrease in enzyme activity: AST - by 47.5%, ALT - by 19.9%, alkaline phosphatase - by 1.59 times, and correction of the mineral component of blood serum.

Abstract
The article presents experimental data on the influence of the feeding diet on the biochemical blood parameters of laying hens. As feed additives in the poultry diet were used: feed vitamin-mineral concentrate (FVMC) in the amount of 0.3% of the basic diet (BD) (1st experimental group), probiotic additive “Bacell-M” in the amount of 0.2% of BD (2nd experimental group), complex feed concentrate (CFC), containing FVMC and probiotic additive “Bacell-M”, in the amount of 0.3% of BD (3rd experimental group). The control group received only BD. It was found that the introduction of the feed additives into the diet of laying hens stimulated the metabolic processes in the poultry body, which was manifested by an increase in a number of biochemical constants. So, the level of total protein in the 1st experimental group increased by 34%, in the 2nd and 3rd experimental groups it increased in 1.43 and 1.42 times in comparison with the control group. The urea concentration exceeded the analogical values of the control poultry by 27% (1st experimental group), by 23.2% (2nd experimental group) and by 24.3% (3rd experimental group), respectively. The use of feed additives influenced the state of carbohydrate and lipid metabolism of hens, which was manifested by an increase in glucose concentration in the groups by 6.3%, 13.1% and 21.5% and by an increase of triglycerides by 13.2%, in 1.7 and in 2.0 times respectively. The inclusion of additives in the feeding schemes contributed to the correction of mineral metabolism, providing more complete absorption of calcium by the poultry, the increase of which in the experimental groups was by 16.2%, 1.68% and in 2.21 times, and also prevented the development of hepatocyte cytolysis, as indicated by a decrease in the activity of hepatoindicatory of enzymes: ALT decreased by 9.8%, 29.5% and in 1.85 times, AST decreased by 7.9%, 12.7% and 18.9%, respectively. The maximum positive effect in the indicators of the biochemical status of laying hens was observed when CFC was used in the diet, which was due to the synergy of FVMC and the Bacell-M probiotic additive.

AbstractRecently, the importance of studying the biodiversity of the Vitaceae Juss family. increases markedly, while new data appear on the gene pool of cultivated and wild-growing grapes Vitis vinifera L. Modern methods of analyzing the polymorphism of populations of grape plants, both wild-growing and cultural, are actively used. According to the literature, a number of studies have been conducted in the Russian Federation to study native varieties and wild forms of grapes in the Crimea, Dagestan, along the banks of the Don and other regions, but there is very little information about Kuban wild and ancient forms of grapes. The article presents the results of a study of wild forms of the genus Vitis L., growing in places of ancient human settlements on the territory of the Utrish State Nature Reserve of the Krasnodar Territory. For the first time, ampelographically and genetically samples of isolated populations of wild grapes growing on the territory of the Utrish State Nature Reserve have been studied and described. Several habitats of wild grapes, presumably belonging to the Vitis vinifera ssp species, have been studied. Silvestris Gmel. or its variants var. Tipica Negr. - typically wild forest grapes. A detailed description of phytocenoses in which the studied plant forms grow is carried out. Ecological and geographical characteristics of their habitats are given. Samples were taken for further genetic analysis. DNA-marker analysis of plant genotypes by microsatellite loci VVMD27, VVMD5, VS2, VrZAG79 recommended for genotyping of grapes was performed. It was shown that some of the samples are polymorphic to each other, while others are genetically close. When analyzing genotypes, rare alleles were detected for the analyzed SSR loci.

Published: September 2020

AbstractThe study of deformation hardening of single crystals for modern engineering is an important task due to the emergence of new promising methods of processing metal materials. Although in practice we usually deal with polycrystalline metals and alloys, it is advisable to start the analysis with simpler objects – single crystals of pure metals, where you can most clearly and fully identify the main patterns of deformation hardening. The article considers the temperature range limited by the interval of intensive thermal return.
Influence of heat treatment on the presence of a rock-like fracture of steel 35 HGSL
Authors: Skryabin M L 
Published: September 2020

Abstract
The article discusses the features of the formation of a rock-like fault, which is formed at an elevated temperature and is enriched with partially soluble phases. These are small particles, films, or fused eutectic. To study the regularities of this defect, 8 different melts were studied and micro-samples were made for further research. The study of the structure revealed the main parameters that have a destructive effect on the metal. In general, the studied defect can be corrected by homogenization, which is determined by the degree of stability of the rock-like crack - the more stable it is, the higher the heating temperature should be and the longer the exposure at this temperature.

Abstract
The basis for in-depth studies of the southwestern district of the city of Abakan vegetation, the Republic of Khakassia was the lack of information on the current status, structure and species composition of the whole city flora. Targeted floristic studies in the city of Abakan were not conducted. Since the mid-twentieth century, study of plant cover of the Republic of Khakassia was engaged in prominent botany of the Siberian scientific and educational institutions of Siberia, but most of them were passing through the city of Abakan. The study of the flora was held by the honored worker of the Russian Federation Krasnoborov I. M. while working at the Herbarium of Khakass state university (KhSU) and Associate Professor of KhSU T. M. Zorkina. Flora of the South-Western area was identified based on field research expedition model area (MA) within the administrative boundaries of the city of Abakan in 2017-2018, the study of literature data and herbarium materials of the Krasnoyarsk state pedagogical University (KSPU) and Khakass state university (KhSU). Most of the territory of MA have been visited repeatedly and at different times of the growing season, and that suggests the method of urbanized landscape model areas. South-Western residential district of the city of Abakan, (known as the village of MR - Ministry of the Railways), consists entirely of multifamily housing, in 2011 there was a Komsomol Park, which determined the composition and structure of its flora. The taxonomic spectrum of the flora of the southwestern district of the city of Abakan includes 16 families of the world flora, of which only 3 families are with identical ranks: an Asteraceae, Fabaceae, Scrophulariaceae. The taxonomic spectrum of the flora of the southwestern district of the city of Abakan is of Brassicaceae-type, Fabaceae-subtype – extreme-book Mediterranean, which corresponds to the position of the city of Abakan in the steppe zone of Eurasia and belonging to the Boreal floristic region.

Abstract
The article presents a study on steers’ biological growth patterns that are possible to be considered for increasing the meat productivity of steers. To enhance the live weight gain of Holstein steers, we used a variable feeding system that is based on the physiological characteristics of metabolism and takes into account growing periods and the nature of nutrient absorption by periods, corresponding to the S-shaped growth curve. Analyzing growth records of young cattle, he paid attention to some patterns of the live weight gain. These data showed that the live weight gain was uneven along the S-curve and subject to periodic fluctuations that were characterized by decreases and increases in growth; a period took 12 days, that is, the amplitude of the increase in growth made 12 days and then the decrease was also 12 days. We also divided the growth cycle into 2 periods, 12 days each. In the increase period, if the amount of feed was reduced by 20%, there was no decrease in average daily gain in steers, and vice versa, in the 12-day decrease period, a 20% increase in feed compensated for the low level of metabolism in the body with a stable rate of average daily gains. Therefore, similar amount of feed can help the traditional cattle breeding system increase the average daily gain by 8.5% and the carcass weight by 10.5% and reduce feed costs per 1 kg of gain by 7.1%.
Two-level systems and growth-induced metastability in hydrogenated amorphous silicon
Authors: Molina-Ruiz M , Jacks H C , Queen D R , Wang Q , Crandall R S , Hellman F 
Published: September 2020

Abstract
Specific heat measurements from 2 to 300 K of hydrogenated amorphous silicon prepared by hot-wire chemical vapor deposition show a large excess specific heat at low temperature, significantly larger than the Debye specific heat calculated from the measured sound velocity. The as-prepared films have a Schottky anomaly that is associated with metastable hydrogen in the amorphous network, as well as large linear and excess cubic term commonly associated with tunneling two-level systems in amorphous solids. Annealing at 200 °C, a temperature that enables hydrogen mobility but not evaporation, irreversibly reduces the heat capacity, eliminating the Schottky anomaly and leaving a reduced linear heat capacity. A non-monotonic dependence on growth temperature and H content is observed in all effects, except for sound velocity, which suggests that the tunneling two-level systems and the Schottky anomaly are associated with atomic hydrogen and require low density regions to form, while sound velocity is associated with the silicon network and increases with increasing growth temperature.

Published: September 2020

Abstract
A highly transparent and super-hydrophilic double-layer anti-reflection coating was prepared by a simple and economical sol-gel method based on the glass substrate. The bottom and top layer were respectively made with SiO2–TiO2 sol and SiO2–TiO2-PEG300 sol. The average transmittance of the substrate coated with the double-layer coating is increased by 7% up to 97.4% in the visible light band, and the peak transmittance reaches 99% at about 550 nm. In addition, double-layer anti-reflection coating shows a good super-hydrophilic self-cleaning performance, and the transmittance of the coating can be restored by simple washing with water. Furthermore, due to the existence of anatase TiO2, the composite coating can restore the super-hydrophilicity damaged by dust under UV light.
A new optimization algorithm for HDR brachytherapy that improves DVH-based planning: Truncated Conditional Value-at-Risk (TCVaR)
Authors: Wu Victor W , Epelman Marina A , Pasupathy Kalyan S , Sir Mustafa Y , Deufel Christopher L 
Published: September 2020

Abstract

Purpose: To introduce a new optimization algorithm that improves DVH results and is designed for the type of heterogeneous dose distributions that occur in brachytherapy. Methods: The new optimization algorithm is based on a prior mathematical approach that uses mean doses of the DVH metric tails. The prior mean dose approach is referred to as conditional value-at-risk (CVaR), and unfortunately produces noticeably worse DVH metric results than gradient-based approaches. We have improved upon the CVaR approach, using the so-called Truncated CVaR (TCVaR), by excluding the hottest or coldest voxels in the structure from the calculations of the mean dose of the tail. Our approach applies an iterative sequence of convex approximations to improve the selection of the excluded voxels. Data Envelopment Analysis was used to quantify the sensitivity of TCVaR results to parameter choice and to compare the quality of a library of 256 TCVaR plans created for each of prostate, breast, and cervix treatment sites with commercially-generated plans. Results: In terms of traditional DVH metrics, TCVaR outperformed CVaR and the improvements increased monotonically as more iterations were used to identify and exclude the hottest/coldest voxels from the optimization problem. TCVaR also outperformed the Eclipse-Brachyvision TPS, with an improvement in PTVD95% (for equivalent organ-at-risk doses) of up to 5% (prostate), 3% (breast), and 1% (cervix). Conclusions: A novel optimization algorithm for HDR treatment planning produced plans with superior DVH metrics compared with a prior convex optimization algorithm as well as Eclipse-Brachyvision. The algorithm is computationally efficient and has potential applications as a primary optimization algorithm or quality assurance for existing optimization approaches.
