Geoinformational technologies in the problem of assessing the pesticides’ impact on the arid zones soils’ condition
Authors: Kosarev A V , Komleva N E , Dolich V N , Ivanov D E 
Published: March 2021

Abstract
The work is devoted to establishing the influence of aridity on the risk of negative soil changes caused by residual pesticides presence in spring and autumn. Using the Earth’s remote sensing method, it is shown that the NDMI index is decreasing and aridity is increasing in the following direction: Lipetsk Oblast- Kursk Oblast - Voronezh Oblast-Belgorod Oblast-Ulyanovsk Oblast -Samara Oblast -Saratov Oblast - Penza Oblast -Orenburg Oblast --Stavropol Krai-Karachay-Cherkessia. Correspondence was established between the increase in region’s aridity and the increase in the risk increment value for the period from spring to autumn due to the presence of residual pesticide content in the soil. This circumstance can be associated with pesticides accumulation in the soil cover, an increase in their consumption and a decrease in destruction in conditions of arid climate. DDT and hexachlorocyclohexane cause the highest risk increment due to soil accumulation, trifluraline is more subjected to conversion in the soil, has less effect on risk change of soil agroecological condition.

Published: March 2021

Abstract

Halothamnus subaphyllus (C.A. Mey.) Botsch. – is a wild shrub, a potential fodder plant for introduction to culture in arid regions of Russia. This plant is well eaten by sheep, goats, horses, and camels. In bud stage, it contains 24.7% of protein, 2.7% of fat, 36.9% of nitrogen-free extractive substances, and 18.2% of fiber. Ecologically it is a haloxerophyte. Halothamnus subaphyllus is resistant to drought and tolerant to soil salinization. In introducing a new fodder plant into the culture, it is very essential to know the possibilities of its accelerated reproduction. Thus, we studied the reproductive biology and seed productivity of this plant in arid conditions. The initial blossom of Halothamnus subaphyllus is late May-mid-June. Halothamnus subaphyllus is a self-fertile plant. In the first year of life, this plant generates an average of 15.5 g of seeds per shrub. In the second and third years, seed productivity grows and reaches an average of 236.1 g per shrub, with 1 ha of 300-350 kg of seeds. Net reproduction of Halothamnus subaphyllus is 30-35. It means that the obtained seeds can be sown on 30-35 hectares of planted acreage.

The problem of land use in conditions of food security provision
Authors: Rogatnev Yu M , Veselova M N 
Published: March 2021

Abstract
As a result of the land reform, a new land system was formed, which gave rise to new phenomena in the land use system in the conditions of the market economy. The most important new problems of modern land use include the elimination of significant arable land areas from agricultural circulation. The paper proposes a comprehensive consideration of the possible involvement of these unused lands. It is based on taking into account natural and assessing the suitability of arable land usage in certain natural climatic conditions. The market economy requires arable land to ensure the efficiency of crop production. Actually usable land resources can provide sustainable or unsustainable efficiency. Sustainable inefficiency indicates the unsuitability of individual arable sites for efficient crop production. The natural and economic land potential can be used sufficiently effectively only if there are sufficient conditions to ensure production by labor, technical means, basic means of production, financial resources. Involvement of unused land is solved only as a complex problem. This is the correct and balanced approach and implementation of State programs in the field of land use that ensures food security.

Research and modeling of the wear process of parts of the soil tillage working implements
Authors: Dzhabborov N I , Dobrinov A V , Jabborov P N 
Published: March 2021

AbstractIncreasing the wear resistance of parts of tillage working implements and increasing their resource is an urgent problem. A decrease in the resource of tillage working implements occurs due to uneven wear of their parts and soil features. Accelerated wear of working surfaces reduces the quality of soil cultivation, increases the traction resistance of tillage machinery and thereby allows to an increase in the energy intensity of soil cultivation technology.The article presents the mathematical models developed by the authors that describe the process of interaction of the soil with the surface of parts of soil-cultivating working implements during their surfacing with hard alloys. The developed mathematical models make it possible to predict the values of traction resistance, the magnitude and rate of wear of the tillage working implements. The results of experimental studies confirm the adequacy of the developed mathematical models and indicate that the deposition of hard-facing from hard alloys of certain sizes and configurations on the working surfaces of the parts of soil-cultivating working implements ensures their wear resistance when working in an abrasive soil environment. The results of experimental studies of a plowing unit consisting of tractor MTZ-920 tractor and plow PLN-3-35 for sod-medium podzol, medium loamy (light loamy) soils on moraine loam showed that the wear resistance of the deposited share is 2.54 times higher than the wear resistance of the standard ( serial) plowshares without surfacing.

Authors: Yu Karpukhin M , Keita F 
Published: March 2021

Abstract
Potato is the most important agricultural crop in the world and in Russia. Currently, in production are used varieties of domestic and foreign selection. Along with the yield, the products obtained are of great importance, according to which the intended purpose of a particular variety is determined. The study of the quality indicators of potato tubers is an integral part of the development of varietal cultivation technology. The purpose of the research is to study the qualitative indicators of potato tubers of the Gala variety at different plant densities and the use of fungicides in the Middle Urals. The research was carried out in 2018-2019 on the experimental field of the educational and experimental farm of the Ural State Agrarian University. The object of research is a medium-early high-yielding potato variety Gala. When conducting biochemical and agrochemical studies, gravimetric, extraction, ebuliostatic, ionometric and photometric methods were used. The electrical conductivity of tubers was determined with a conduct meter in mSm, the concentration of cell juice with a refract meter in %, nitrates in tubers – with a nitrate tester in mg/kg, the acidity (pH) of tubers – with a pH meter. The research results showed that the concentration of potato tubers cell juice decreases from 7.0 to 2.65% with an increase in the feeding area from 1400 to 2800 cm2. The use of fungicides shirlan and infinito reduces the electrical conductivity. The specific weight of potato tubers increases with an increase in the feeding area from 0.92 to 1.16 grams. The nitrate content decreased with an increase in the feeding area and the use of fungicides from 340 to 326 mg/kg. During the growing period, the content of carbon dioxide (CO2) of the potato plant in the control variant was 775, and with the use of shirlan it was 1043, which is an increase of 1.5 times. The scientific novelty lies in the fact that for the first time in the conditions of the Middle Urals, an assessment of tubers was carried out according to physiological, agrophysical and agrochemical indicators with new devices during the periods of storage of tubers (April) and vegetation of potato plants, depending on the feeding area and the use of fungicides.

Abstract
Modern high-performance agricultural technologies have a negative impact on the biochemical state of soils and on the environment as a whole. Excessive and uncontrolled use of pesticides and mineral fertilizers causes contamination of groundwater and soil. Consumers have a need to purchase environmentally friendly food products that have been produced using environmentally friendly technologies. The use of social networks in the promotion of goods and services of agricultural enterprises allows, in our opinion, to increase the competitiveness of an agricultural enterprise producing environmentally friendly food products and attract an additional number of potential consumers. For effective promotion of goods and services through the use of social networks, it is necessary to create high-quality virtual content with the use of qualified specialists. It is the high-quality content of the virtual space of the social network that will provide potential consumers with information about the services and goods offered by the enterprise and their advantage in relation to the services and goods of other manufacturers.
Simulating twistronics in acoustic metamaterials

Published: March 2021

Abstract
Twisted van der Waals heterostructures have recently emerged as a tunable platform for studying correlated electrons. However, these materials require laborious and expensive effort for both theoretical and experimental exploration. Here we numerically simulate twistronic behavior in acoustic metamaterials composed of interconnected air cavities in two stacked steel plates. Our classical analog of twisted bilayer graphene perfectly replicates the band structures of its quantum counterpart, including mode localization at a magic angle of 1.12∘. By tuning the thickness of the interlayer membrane, we reach a regime of strong interlayer tunneling where the acoustic magic angle appears as high as 6.01∘, equivalent to applying 130 GPa to twisted bilayer graphene. In this regime, the localized modes are over five times closer together than at 1.12∘, increasing the strength of any emergent non-linear acoustic couplings.
Reasons for the stable existence of γ’ phase and strengthening mechanism of GH4720Li nickel-based superalloy
Authors: Zishuai Chen , Ruifeng Dong , Jingnan Li , Xiangtao Deng , Wei Zhang , Xiulan Ren 
Published: March 2021

Abstract
The characteristics of γ′ phase in forgings and heat treatment of GH4720Li superalloy were investigated under a transmission electron microscope by thermal deformation tests under gradient heating process. The experimental results show that there are Cr–Co rich region around the γ′ phase after forging and heat treatment, which guarantees the stable existence of the γ′ phase in the matrix and provides the first barrier to prevent dislocations from cutting the γ′ phase. Therefore, the stable existence of primary γ′ at relatively high temperature plays a key role in the retention of fine grains; The Cr–Co rich region around the secondary γ′ phase and the tertiary γ′ phase can effectively prevent the occurrence of Ostwald ripening, and maintain the uniform and diffuse two kinds of small size phases, so the precipitation strengthening effect is greatly affected.
TOPAS a tool to evaluate the impact of cell geometry and radionuclide on alpha particle therapy
Authors: Guerra Liberal Francisco D C , McMahon Stephen J , Prise Kevin M 
Published: March 2021

Abstract
Due to the increasing clinical application of alpha particles, accurate assessment of their dosimetry at the cellular scale should be strongly advocated. Although observations of the impact of cell and nuclear geometry have been previously reported, this effect has not been fully quantified. Additionally, alpha particle dosimetry presents several challenges and most conventional methodologies have poor resolution and are limited to average parameters across populations of cells. Meaningful dosimetry studies with alpha particles require detailed information on the geometry of the target at a subcellular scale. Methods. The impact of cellular geometry was evaluated for 3 different scenarios, a spherical cell with a concentric nucleus, a spherical cell with an eccentric nucleus and a model of a cell attached to a flask, consisting of a hemispherical oblate ellipsoid, all exposed to 1,700 211At radionuclide decays. We also evaluated the cross-irradiation of alpha particles as function of distance to a source cell. Finally, a nanodosimetric analysis of absorbed dose to the nucleus of a cell exposed to 1 Gy of different alpha emitting radionuclides was performed. Results. Simulated data shows the dosimetry of self-absorbed-dose strongly depends on activity localization in the source cell, but that activity localization within the source cell did not significantly affect the cross absorbed dose even when cells are in direct contact with each other. Additionally, nanodosimetric analysis failed to show any significant differences in the energy deposition profile between different alpha particle emitters. Conclusions. The collected data allows a better understanding of the dosimetry of alpha particles emitters at the sub-cellular scale. Dosimetric variations between different cellular configurations can generate complications and confounding factors for the translation of dosimetric outcomes into clinical settings, but effects of different radionuclides are generally similar.
High field conduction in mineral oil based ZnO nanofluids prior to negative streamer inception
Authors: Becerra Marley , Aljure Mauricio , Masoud Pourrahimi Amir , Roman Francisco 
Published: March 2021

Abstract
The electric conduction under intense electric fields (up to ∼ 109 V/m) in nanofluids using surface-modified ZnO–C18 nanoparticles dispersed in mineral oil as host, is investigated with both experiments and numerical simulations. The measurements are used to estimate unknown parameters necessary to represent the generation and loss of electrons in an electrohydrodynamic model for mineral oil with and without ZnO–C18 nanoparticles in a needle-plane configuration. The model suggests that ZnO–C18 nanoparticles induce an enhanced field emission from negative needles, explaining the significantly larger conduction currents measured in the nanofluid compared with those in the host liquid. It is also found that the scavenging of electrons by ZnO–C18 nanoparticles is a process which is negligible compared with the loss of electrons due to attachment in mineral oil. It is shown that ZnO–C18 nanoparticles hinder the streamer initiation process by reducing the effective electric field at the tip of the needle. This electric field reduction is caused by the combined effect of enhanced electron injection through ZnO–C18 nanoparticles and strong electron attachment in mineral oil. Thus, the electric field on the needle tip reaches the same threshold value when the streamer is incepted in the nanofluid as in mineral oil, although at a larger voltage. Solid evidence indicating that the additional electron scavenging and the reduced electron mobility introduced by nanoparticles has no effect in the conduction currents and in the negative streamer inception in the tested ZnO–C18 nanofluids is shown.
