Authors: Popov Yu V
Published: April 2021

Formation homogenity and geodynamic conditions for the formation of apohyperbasites is an actual problem in geological study of the Paleozoic complexes of the Greater Caucasus. Study results of chromespinelids from serpentinite fragments of Paleozoic tectonic melange in the Western part of the Greater Caucasus (outcrops in Dakhovskiy uplift and Kisha river) tested with electron microprobe methods and processing of the results of elemental analysis using non-parametric statistics lead to the conclusion that apohyperbasites belong to ophiolites of subduction environments. Their composition is close to chromespinelids’ of ophiolite complexes of supra-subduction zones (SSZ) composition. Chromespinelides from the flank of Dakhovskoye uplift are represented by subferrochromite cores with rims of magnetite; transformation of subferrochromites during obduction process (Cr# ∼0.80-0.81, Mg# ∼0.35-0.40 in the least modified cores) in to chromites occurred under the conditions of the greenshist facies and was accompanied with redistribution and removal of aluminum and magnesium, and enrichment with iron and chromium. Chromespinelides from the serpentinites of contact Agarinskiy and Kizilkol’skiy thrust sheets presented with cores of aluminumchromite with relics of chrompicotites (Cr# ∼0.50-0.70, Mg# ∼0.39-0.64), surrounded by rims of ferrochromite – chromomagnetite. This transformation occurred on the boundary of the greenschist and low-temperature zone of the amphibolite facies and was accompanied by the substitution with iron for both two-and trivalent cations.

Authors: Merkushev S A , Khusnutdinova S R , Khusnutdinov R R
Published: April 2021

The article is devoted to the study of the existing system of passenger rail transport in cities with a population of one million. Transport infrastructure is an important element of urban infrastructure and participates in the formation of agglomeration links. The article discusses the issue of the connectivity of the outer zone of the city with the agglomeration due to the existing system of using rail transport. Three cities with a population of one million, with similar socio-economic and physical-geographical characteristics - Yekaterinburg, Kazan and Perm, were selected as territorial objects. The similar and different aspects of the formed passenger railway transport systems are revealed. It is concluded that the integral indicator of the level of development of suburban and intracity transport links of external zones demonstrates a strong Perm lag behind Yekaterinburg and Kazan. Yekaterinburg and Kazan possess highly differentiated links between the individual sectors of the city’s outer zone. The “gap” between cities also takes place without taking into account the integration of electric trains with the metro, and becomes even stronger when taking into account the interaction of the two off-street transport systems.

Published: April 2021

This article is about features of geological structure and composition of volcanic and sedimentary rocks of the Low Taiga area (Russia, Primorsky region). This area is a part of the east Sihote-Alin volcanoplutonic belt, is located in the area of transit from the continent to the ocean. Studings of geological and chemical composition, structure and patterns of placement of the Low Taiga Area’s volcanic sedimentary rocks allow us to complete information about geological and geochemical features of Mesozoic-Cenozoic stage of the formation of the said structure. Unever igneous formations are distributed within this area, classified to Primorsky (turonian senonian), Samarga (maastrichtian), Bogopolsky (Paleocene) and Kizinsky (Miocene) volcanic complexes. Matching volcanic rocks complex’s chemical composition with published data testifies to significant similarity with petrotypes of ternei volcano structure. Besides it was found that the Low Taiga Area’s complexes contain high potassium varieties and vary in contents of rare and rare earth elements. Distribution of incoherent elements of primorsky complex’s volcanics are characterized by increased concentrations of tungsten, zinc, plumbum, thorium, lanthanum, cerium, by low content of niobium, strontium, zirconium and titanium. Samarga complex is characterized by low content of titanium and strontium, by low content of neodymium. Bogopolsky and Kizinsky complexes in the distribution of rare and trace elements have a similar trend appearance with petrotypes, but differ in the level of their concentration.

Of these, 38.9% belonged to S. agalactae, 33.3% to S. dysgalactae, and S. equi subsp. zooepidemicus - 22.2%. A small number of isolates -5.6% belonged to the species S. equi subsp. equi and S. uberis. in The test with mouse peritoneal macrophages shows that the antiphagocytic activity was 75% for isolates of S. zooepidemicus, 57% for S. agalactiae, and 64% for S. dysgalactiae. At the same time, the phagocytic number and phagocytic index were higher in the phagocytosis of the most strains featured with trypsin compared to the initial ones indicating to the antiphagocytic role of the pathogenic structures presented in them at the stage of bacteria capture. The numbers of factors of streptococci pathogenicity including M-proteins make them able to resist opsonization and phagocytosis
Sweep-Soil Interaction: a Mathematical Model
Authors: Zaripova N A , Soyunov A S , Algazin D N , Kulaeva A G , Kuzmin D E
Published: April 2021

Cutting-edge tillage machinery design involves the evolving theory of implement-soil interaction. This paper proposes a mathematical model that represents the performance indicators of a sweep (soil deformation, draught, contact pressure) as a function of design and operating factors (note: this paper covers low-crown sweeps). Analysis of these equations and the results of field experiments show that increasing the nose angle will reduce the drag and require less force to cut the stubbles. As the cutting angle increases, more force is required to cut through; the penetration ability is directly proportional to cosα.

Authors: Vysotskaya M V , Okhotkina V E , Blinovskaya Ya Yu , Vysotsky M V
Published: April 2021

The growing pollution of coastal-marine areas with litter, mainly plastic, is of concern to both the public and the scientific community around the world. The amount of waste in various, even hard-to-reach, coastal areas is increasing annually, as evidenced by the numerous activities carried out regularly within the framework of diverse environmental projects. The unique geographical position of Primorsky Krai makes its coastline attractive for almost all types of marine recreation and, as a result, does not leave aside the growing problem of anthropogenic impact. The 12-year cycle of studies carried out on the coasts of the Primorsky Krai, differing both in physical-geographical and socio-economic conditions, reveals a predominantly “recreational type” of coastal pollution and suggests that there were no statistically significant changes in the total amount of collected waste on the coasts (taking into account the annually increasing cleaning efforts). At the same time, the studies demonstrate the value of the data obtained as a serious basis for the formation of a unified methodology for monitoring marine litter in the coastal zone - the most important methodological stage on the way to solving the problem of pollution of the coasts of not only Primorsky Krai, but also other regions with anthropogenic litter.

Published: April 2021

The article summarizes the results of the authors’ scientific works and their own research on the adaptation of Yakut cattle and their crossbreeds with the Simmental breed to specific climatic and economic conditions of keeping. The paper highlights outstanding fat content (5.5…5.58%), excellent compensatory growth energy with free summer feeding (700…900 g per day), high coefficient of digestion of coarse feed fiber (74%), Yakut cattle’s unique resistance and adaptation to adverse weather, economic conditions of breeding, the degree of their inheritance in crossbreed livestock. The article presents materials for studying the morphobiological composition of blood, thermoregulation, skin and hair cover, development of internal organs, gas-energy metabolism, digestibility and use of feed nutrients. It is indicated that when crossing Yakut cattle with Simmental breed with an increase in genetic generation of crossbreeds, its valuable economic and adaptive qualities disappear. The task of protecting the gene pool of local native Yakut cattle and increasing its livestock and geographic range, improving nutrition concerns not so much its higher productivity, but the preservation of the valuable nutritional qualities of its dairy and meat products as well as of its adaptive potential to local conditions in the offspring. When local Simmental (87% of the population) and Kholmogorsky (12% of the population) cattle breeds are kept with generally accepted methods of artificial selection aimed at increasing productivity and improving hereditary qualities, it is necessary to simultaneously conduct adaptive selection by preserving the valuable qualities of the Yakut cattle gene pool in the offspring.

Published: April 2021

The article analyzed the possibility of using saponite as an ameliorant. In a model experiment, the effect of saponite on soil acidity, the content of biogenic elements (nitrogen, phosphorus, potassium), and productivity were studied. We found that introducing various doses of saponite does not affect the accumulation of water in the soil. It does not play the role of a deoxidizer and does not saturate the soil with nutrients, but prevents the removal of mobile nitrogen and potassium from the soil. Saponite does not increase soil productivity, but can affect the green mass productivity.

Authors: Denisov Konstantin , Kibalnik Oksana , Efremova Irina , Bochkareva Julia
Published: April 2021

Experimental studies of the effect of chelated forms of fertilizers on sorghum yield in arid conditions have been carried out. It is found out that to increase productivity and improve the main economic characteristics of a crop, it is advisable to use liquid chelated micronutrient fertilizers Reasil Forte Carb-Ca / Mg / B-Amino and Reasil micro Amino Zn as foliar application in the phase of 5-7 leaves (first treatment) with subsequent treatments after 10 days. It is proved that this method provides an increase in the yield of grain and green mass of sorghum by 0.27-0.60 and 27.1-39.9 t/ha, respectively, and also increases the content of valuable amino acids in the green mass: arginine, threonine, isoleucine, valine, and phenylalanine, which in turn increases the nutritional value of sorghum green mass for feeding farm animals. It is concluded that foliar application with micronutrient fertilizers reduces plant stress from unfavorable climatic conditions, which leads to stabilization of yields over the years and partially removes dependence on weather conditions.

Published: April 2021

Sturgeon species of fish are a unique branch of the relict fish fauna. Species biodiversity, features of biology, a wide range, nutritional value, all taken together, made it possible to distinguish this group of fish in an independent direction-sturgeon breeding. In the last century, Russia accounted for up to 90% of the world’s stocks of these fish species. According to the number and species composition of sturgeon, the Caspian basin occupied a dominant position. Nevertheless, over the past 15-20 years, there has been a landslide undermining of the unique stocks of sturgeon fish in this reservoir. The main reason for the reduction of sturgeon stocks is the excess of the removal of populations over their replenishment. Against this unfavorable background, it became necessary to form broodstock in order to compensate for the decreasing number of wild breeders. To solve this problem, two main directions have been formed in sturgeon breeding – the domestication of wild fish and the cultivation of mature breeders in artificial conditions on the principle of “from eggs to eggs”. In the article, fish-biological and physiological indices of the first mature females of beluga grown in the natural background annual dynamics of water-medium temperature by the principle “from eggs to eggs”.

Published: April 2021

The modified submersible rotating biofilter MSRB was developed and patented to improve the efficiency of wastewater treatment in small settlements in Syria by performing structural modifications in the biofilter body without the need for additional aeration elements. 112 experiments were carried out on two types of biomass carriers and, as a result, optimal pairs of technological parameters were obtained to achieve the highest oxygen transfer rate OTR values. The highest values of the OTR when using the first biomass carrier were at the low filling percentage of the drum of 60% and immersion depth of the drum in the liquid 35%, while the highest values of OTR when using the second biomass carrier were at the high filling percentage of the drum 90% and low immersion depth 15%. Comparison of the obtained values of the standard aeration efficiency SAE for the MSRB with the results of similar studies showed that the SAE values of the MSRB increased by 58.29%.
On the formation of environmental consciousness among students of an agricultural university
Authors: Krasilnikova E V , Kuznecova S N
Published: April 2021

The paper analyzes the phenomenon of environmental awareness and educational technology of its formation among the students of an agricultural university. The definition of ecological consciousness is used as the ability to build a relationship with the surrounding natural world in accordance with the law of harmonious and sustainable development of a modern technogenic society. At the same time, the work puts forward an understanding of environmental consciousness as a factor that builds a person’s relationship with the social world, which determines the worldview maturity of a person himself as a person. The latter makes environmental awareness not only an important component of environmental safety, but a guarantor of the existence of culture as a whole, in connection with which there is an urgent need to develop a strategy for the formation of environmental awareness among young people. The special role of educational institutions in the formation of environmental awareness as an important component of the educational process is indicated. The experience of research and teaching and educational work of teachers of the Department of Botany and Meadow Ecosystems and the Department of Humanities of the Tver State Agricultural Academy on the formation of environmental awareness among students is presented. One of the effective forms of extracurricular and research work is analyzed - project activity, an innovative method that contributes to the development of ecological consciousness and ecological lifestyle of students. Reconstructed the main stages of a pilot project demonstrating the benefits of growing environmentally friendly vegetable products. An educational project - “The World of a Russian Estate”, which forms the basic values necessary to preserve the ecological consciousness of young people, is presented.
Environmental management of natural-anthropogenic complexes of rural areas
Authors: Nardin D S , Nardina S A
Published: April 2021

The article presents the results of the study of natural-anthropogenic complexes of rural areas as self-developing polysubject environments. In this case, a self-developing polysubject environment is understood as a set of subjects that form the technological, social, economic and ecological subsystems of natural-anthropogenic complexes, taking into account their values and culture. Such an approach to determining the object of management is characteristic of the post-nonclassical type of scientific rationality, within which management is carried out through the impact on the environment, culture and values. Currently, in relation to the natural-anthropogenic complexes of rural areas, separate elements of such a management system are being formed, which, nevertheless, are already showing certain efficiency. In this article, the authors made an attempt to identify and describe the elements of environmental management using the example of managing the sustainable development of natural-anthropogenic complexes that are formed in the process of grain production.

Published: April 2021

The strontium content in phosphogypsum, soil and plants has been studied. It has been established that during the processing of phosphate raw materials, most of the strontium passes into phosphogypsum, reaching 1.4-2.3% in it. With the introduction of a single dose of phosphogypsum (23 t / ha), the content of total strontium in the soil increased to 309-364, and a double dose to 402, which is below the maximum permissible level (600 mg / kg). The ratio between calcium and strontium in the medium sodium reclaimed chernozem solonetz was at a good and satisfactory level, and in plants it was more than 100, which is typical for territories with a relatively satisfactory ecological situation. Meliorative (calculated) agronomic and ecologically safe rates of phosphogypsum consumption for soils of solonetzic complexes of the Volga economic region are given.
