Authors: Aseeva A V , Kislov E V 
Published: April 2021

Abstract
A new occurrence of gem corundum was discovered in the vicinity of Naryn-Gol Creek, on the Dzhida volcanic field, Russia. Sapphires were found in both alluvial deposits of the Naryn-Gol Creek and pyroclastic rocks of the nearby Cenozoic alkali basalt volcano Barun-Hobol Pravyi. These rocks contain, in addition to sapphire, large crystals of garnet, spinel, augite, olivine, enstatite, ilmenite, and feldspar. Chemical composition of the sapphires overall is typical for corundum from basalt: rich in Fe, low in Ti and Cr. The oxygen isotopic compositions of corundum and associated minerals show δ18Osmow values ranging between 4.6‰ and 6.8‰ that is attributed to magmatic rocks. Study of impurities reveals the great role of volatiles, CO2, in particular, during the formation process.

Authors: Sentyabov S V 
Published: April 2021

Abstract
The stress state of the concrete walling of mine shafts is formed as a function of the structural parameters of the shaft, the total stress tensor, which includes gravitational-tectonic and time-varying stresses acting in the rock mass at the baseline, taking into account the physical and mechanical properties of the rock mass, the elastic modulus of concrete, which depends on the rate of advance and additional stresses caused by a subsequent change in the stress field, determined outside the zone of influence of mining by a cyclic change in natural stresses, and in the zone of influence of the mined-out space - by a change in the secondary stress field. The paper has presented the results of the research, which significantly increase the degree of geomechanical study of the Gaiskoye deposit’s rock mass. The main purpose of the research was to determine the parameters of the initial stresses acting in the concrete walling of the shafts at different depths. The parameters of stresses acting in the shaft walling at deep mine horizons were determined under field conditions, and the stress-deformed state of the shaft walling at various horizons was monitored throughout the depth of the shaft in the period 2013 - 2020.

Abstract
The paper is devoted to the derivation of the noise level dependences and vibration velocities of elements and units of the drive system of the rail grinding machines. It should be noted that the vibro-acoustic characteristics of the drive system of rail grinding machines have not been studied enough. The negative impact on the operator of the increased vibration and noise levels is known as diseases caused by noise and vibration are the second and third in the list of occupational diseases. It should be highlighted that the safety in the operation of rail grinders largely depends on operator fatigue, which is actually determined by the influence of vibration and noise. Consequently, the problem of the vibro-acoustic safety of the rail grinding machines is relevant and has both technological and socio-economic significance. This article presents the results of theoretical studies of the processes of vibration excitation and generation of wheelset noise as one of the main causes of the increased noise in the general drive acoustic system of the rail grinders.

Published: April 2021

Abstract
It is well known that mycopesticides have significant potential for a plant protection. For example, pathogenic fungi can induce nonspecific defence reactions and stimulate growth of non-host plants. The aim of this work is to evaluate the off-target activities of potential mycopesticides which affect germination, growth and development of crops. The strains of Stagonospora cirsii C-163, Calophoma complanata 32.121, Alternaria sonchi S-102, Beauveria caledonica BB16, BSc13Vg18, BSc25Vg18, Beauveria pseudobassiana BCu22, Beauveria bassiana T7, BHy1-06 were obtained from the pure cultures collection of the All-Russian Institute of Plant Protection. The most significant leaf spot containment (near 70%) was shown by mycelium extract S. cirsii C-163. In the case of leaf rust, the disease containment effect was lower and was observed for mycelium-based suspension of S. cirsii (near 35%). The maximum growth-promoting effect was observed for mycelium-based suspension of C. complanata. Multivariate analysis data showed that the species of B. caledonica and C. complanata are able to inhibit the development of wheat diseases and promote plant growth. Thus, in our opinion, the screening of producer strains should include the assessment of some nonspecific effects on the development and cultivation of plants.

Abstract
In the Russian Federation, the issue of improving the cadastral system is currently more relevant than ever. This is determined by the complication of the procedure for designing and building the cadastral real estate objects. Modern architecture is becoming more complex and diverse year-by-year. The configuration of the construction facilities is becoming more increasingly complex, and these days, they can be built not only on the ground surface but also above or under the ground. In practice, such design solutions lead to uncertainty and ambiguity of their routine cadastral registration, and these objects are registered according to their two-dimensional projection on the ground. Currently, almost all design agencies use 3D simulation in solving issues related to the design, construction, and sale of both industrial or agricultural facilities and residential or office buildings and apartments. Leading Krasnodar enterprises engaged in the design of various real estate objects use three-dimensional models in providing customers with the complete scope of work. The paper authors reveal the basic concepts of a three-dimensional cadastre in a modern system of engineering, design, construction, and architecture. The prerequisites for switching to the 3D cadastre have been considered, the cadastral registration aspects specified, and the issues concerning three-dimensional representation and processing 3D real estate data discussed. The main 3D data representation models are listed.

Authors: Zverkov M S 
Published: April 2021

Abstract
It is noted that the purpose of irrigation systems is to distribute water over the soil surface uniformly in the amount required by plants. The irrigation rate should be less than the soil infiltration rate, and the rain intensities for irrigation should not lead to direct physical damage grown crops to prevent soil problems (mainly erosion and loss of nutrients) and crops caused by runoff and flooding. It is necessary to research the size and shape of the area wetted by artificial rain, depending on the various operating modes of sprinklers and devices. This is especially important when creating irrigation equipment. It is also necessary to assess the distribution of water and determine various technological parameters of irrigation (intensity, rainfall depth, drop size distribution, etc.). The purpose of this research was to analyze wetted area under the stationary sprinkler using a digital equipment. The article describes using the digital equipment, the research design, the method of estimation of the wetted area by jet sprinkler. The device, installed under the sprinkler jet, works on the principle of an acoustic scanner and records the sound signal created by the impact of rain drops. The wetted area covered by rain jet was about 89.1 ± 16.5 square meters, the total irrigation area from one position is 927.5 ± 16.5 square meters. The effectively wetted pattern was less than the measured wetted pattern by 10…15 % approximately. It is shown that with the help of one device it is possible to measure the wetted area, the distribution of raindrops by size and rainfall depth.

Abstract
Nowadays, poultry farms use various technological equipment for keeping and caring for poultry. This also applies to the feeding system. The studies were carried out in the conditions of Kamenskaya Poultry Farm LLC, Altai Territory, on the parent flock of the Ross 308 cross. For the experiment, two experimental groups of birds at the age of 23 weeks, 8355 heads each, were formed from the parent flock. The first group of chickens was fed from traditional, stationary trough feeders. In the second group, a new design of feeders was used -oval in shape, which automatically rose to the ceiling after feeding the birds. In this position, they are filled for the next bird feeding. It was found that the yield of broilers per the initial hen of the parent flock differs between the control and experimental groups (in favor of the experimental group) in all control periods. At the same time, the greatest differences were noted starting from the age of 47 weeks - 3.2%, at 52 weeks - 4.1%, at 57 weeks - 4.8%, and at 62 weeks - 4.1%.

Abstract
The problem of ensuring environmental safety in the handling of drilling waste oil production is relevant throughout the world, but is particularly acute in Russia in almost every oil-producing region. The importance of the problem is determined not only by a significant amount, but also by the negative impact of oil waste on virtually all components of the natural environment. As a result of their impact, there is a significant change in the natural state of the geoecological environment, a decrease in the natural protection of groundwater, activation of geochemical and geomechanical processes, and a change in the natural microbiocenosis. The threatening growth of hazardous oil waste accumulated annually in the absence of the necessary scale of their utilization leads to the seizure of land resources for long periods. At the same time, oil waste belongs to the secondary material resources and by its chemical composition and useful properties can be used in the national economy instead of primary raw materials

Published: April 2021

Abstract
The article deals with the issue of modelling the technical condition of a low-pressure earthen dam of rice systems using numerical calculation methods. The primary task of operating irrigation systems is to rationalize water use by increasing the technological level, improve water management through the use of water-saving technologies and optimal operating modes of the on-farm network of rice systems. Rice is the most productive and water-intensive crop. The most widespread rice cultivation in Russia is in the South, namely in Krasnodar Territory and the Republic of Adygea. The problem of water scarcity in the cultivation of modern rice varieties requires the development of new science-based technological solutions to comply with the regime at the entire stage of cultivation, primarily aimed at saving water resources. Modern approaches and solutions of water regime management at the entire stage of cultivation are relevant with a constant increase in the volume of rice cultivation. A number of numerical experiments were carried out, which can be divided into two groups. In the first group, numerical calculations of the low-pressure earthen dam of the rice check were performed without the formation of landslide processes, where the goal was to establish the adequacy of solid–state models of the stress-strain condition with existing field tests. The pressure from agricultural machinery passing through a low-pressure earthen dam is taken into account. The second group consisted of numerical calculations of low-pressure earthen dam rice check in the formation of landslide processes in the presence of defects, the result of which was to obtain the maximum allowable sizes of damage. There were performed the simulations and evaluated the impact of the identified damage to the technical condition of the structures of on-farm network of rice systems.
