Abstract:

Amber of amber-bearing deposits in Rivne-Volyn region of Ukraine has been analyzed. Relying upon instrumental techniques, physical and chemical as well as spectral analyses, and geological prospecting of the deposits, chemical composition and ultimate composition of amber occurring at the territory of Klesiv deposit (Ukraine, Rivne Region, Sarny District) have been identified. Klesiv amber contains the greatest part of inclusions; it contains 18 chemical elements. Basing upon the performed geological cross-section it has been determined that the amber occur in sandy soil and sandy-shale soil. The depth is insignificant – from 1 m to 10 – 15 m. Moreover, to determine the cost, experimental technique has been developed. The technique involves classification of the amber fragments according to their form, dimensions, and colour. Lithologic-and-facies sections of sites of Klesiv deposit have been obtained.

Abstract:

The studied locality lies in North state of arid to semi-arid climate, where physical-mechanical weathering and denudation processes dominate. The lithostratgraphic sequence in geochronological order (from bottom to top) as high-grade gneisses, low-grade metasedments, serpentinized altrabasic (ophiolite complex) rocks, and younger granitoidal intrusions. Results which were obtained for Au and accompanying elements (Ag, Co, Cu, Pb, and Zn) were subjected to statistical analysis to reveral parameters such as (background value (Cb), coefficient of correlation, coefficient of variation, geochemical factors, productivities, and coefficient of dispersion). Sampling of residual soil was found to be effective in prospecting to reveal anomalous contents of chemical elements in the study area. Statistical methods interpretation of data proved to be effective and complement each other. The coefficients of correlation of Au with the accompanying elements in chip composite samples show values more reliable values for prospecting than those of the soil samples. Gold dispersion in the study area shows erratic behavior. The other mobile elements are dispersed around the mineralized quartz veins. The morphology of secondary dispersion halos of ore elements reflects more or less the morphology of the hidden ore bodies Coefficients of correlation when they are reliable can be used to define pathfinder to prospect for difficult gold. Geochemical factor can indicate horizon of mineralization and level of weathering.

Abstract:

This research investigated the use of sodium carboxymethyl cellulose (CMC) as a reinforcement to improve mechanical properties of loess soil found in northwestern China. The mechanical properties of loess were determined by unconfined compressive strength and split tensile strength tests. Three different contents of CMC were adopted: 0.5%, 1.0%, and 1.5%. The results showed that utilizing CMC reduced the maximum dry density of the loess. The compressive strength, tensile strength, and Young’s modulus are enough to construct low-rise buildings when the CMC content exceeds 1.0%, based on existing standards. This research thus provides a prospective sustainability method for loess stabilization.

Abstract:

Abstract. In the eastern sector of Mexico City the sub soil consists of high contrasting sequences (lacustrine and volcanic inter bedded deposits) that favor the development of erratic fracturing in the surface causing damage to the urban infrastructure. The high-resolution geophysical prospecting are useful tools for the assessment of ground deformation and fracturing associated with land subsidence phenomena. The GPR method allowed to evaluate the fracture propagation and deformation of vulcano-sedimentary sequences at different depths, the main electrical parameters are directly related with the gravimetric and volumetric water content and therefore with the plasticity of the near surface prospected sequences. The active seismology prospection consisted in a combination of Seismic Refraction (SR) and Multichannel Analysis of Surface Waves (MASW) for the estimation of the velocity of the mechanical compressive (P) and the shear (S) waves. The integration of both methods allowed to estimate the geomechanical parameters characterizing the studied sequence, the Poisson Ratio and the volumetric compressibility. The obtained mechanical parameters were correlated with laboratory measured parameters such as plasticity index, density, shear strength and compressibility and, GPR and seismic profiles were correlated with the mapped fracture systems in the study area. Once calibrated, the profiles allowed to identify the lithological contact between lacustrine and volcanic sequences, their variations of thicknesses in depth and to assess the deformation area in the surface. An accurate determination of the geometry of fracturing was of the most importance for the assessment of the geological risk in the study area.

Abstract:

Introduction. Sloping structures (quarry sides, dumps, banks, cuts, dams, etc) stability forecasting accuracy improvement requires detailed elaboration of physical-mechanical properties of the rock mass under consideration. Traditional methods of well engineering-geological exploration and hydrogeological monitoring are therefore supplemented by geophysical study. Research aim is to diagnose unstable deconsolidated and wetted zones in marginal masses for the purpose of further forecast of quarry sides stability. Methodology. Databases of geophysical studies obtained by the expeditions of the services of the Republic of Uzbekistan at Angren open pit. Results. For the test area represented by 11 seismic stations at the southern side of the quarry, the criterion assessing the state of the site as potentially landslide hazardous according to the results of circular seismic sounding has been experimentally obtained. With the use of this criterion, in the plan of the landslide zone the borders have been established. For the test area represented by 16 geophysical profiles at the northers side, by electrical profiling graphs and geological sections for the corresponding profiles, 58 "Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal". No. 1. 2020 ISSN 0536-1028 the following regularities have been found: at profile areas adjacent to the runs (rivers), local negative anomalies of effective resistivity up to 20–50 Ohm ∙ m are observed connected with soils wetting; between the anomalous areas the alternation of effective resistivity qualitatively coincides with the alternation of the thickness of a layer of loose deposits. By the arrangement of the negative anomalies borders at the graphs pf effective resistivity dependence on the spread of the profile along all profiles (PR1–PR16), the borders of the wetted zones were established in the plan of the test area. Summary. For geomechanical processes monitoring in the landslide zones it is advisable to apply the method of circular seismic sounding determining the value and the anisotropy coefficient according to the extreme values of compressional arrival time. For the conditions of the Angren open pit, the criterion of potential hazard of landslide development is the value of the anisotropy coefficient higher than 1.6. When elaborating the detailes of the physical properties of landslide zones in quarry sides which are weakened by sand-clay Quaternary sediments, by the method of electrical profiling it is advisable to use: the linear dependence on the thickness of Quaternary sediments on the value of the effective resistivity; hyperbolic dependence of soils relative wetness within the water saturation zones on the value of the effective resistivity ascribed to the reference value defined in the site of soil samples collection, and the borders of wetting zones are to be established by the negative anomalies at electrical profiling graphs. In order to construct the solid geologicalgeophysical models of the landslide zones of the sides, in addition to the geological sections data, the following results of geophysical sounding should be used: the boundaries of landslide zones in the plan, detailed contact geometry of loose Quaternary sediments with bedrock; soil properties modified by wetting

Abstract:

Over the years, the field of geotechnical engineering focused on physical, chemical and mechanical aspects of the geomaterials. However, recent developments in environmental geotechnics have highlighted the impact of biological processes on geo-materials and their performance. Also, the present day geotechnical problems favour biological interventions to develop eco-friendly and sustainable technology. In view of this, the present study is a preliminary investigation on the impact of microbial loading on fine-grained soils. In addition, a protocol has been developed to establish ‘bio-geo interface’ between bacteria and the geo-material. However, long term studies are demanded in this direction for in-depth understanding of the mechanism for development of prospective application.

Abstract:

Moringa oleifera Lam. is a drought-resistant plant and able to survive in poor soils, obtaining up to three harvests per year. The objective of this work was to study the chemical prospecting of the oil and the bromatological quality of the moringa cake amog different temperatures of drying (40, 55, and 70 ºC) as well as from the oil chemical and mechanical extraction methods. The extracted oils were qualitatively evaluated for acidity, peroxide and iodine levels, as well as the chemical composition of fatty acids by gas chromatography, of samples dried at different drying air temperatures. The pies from mechanical extractions were evaluated for water content, ether extract, crude protein, ash and fibers in neutral detergent. The drying air temperatures of 40, 55, and 70 ºC significantly affected the physical-chemical quality of the oil and the moringa cake, with the best result being the samples from the dry grains at 40 °C. The composition of the main fatty acids was not altered according to the statistical method applied, these being oleic fatty acid (73.60 to 77.07%), erucic (5.65 to 6.67%) and palmitoleic (4.90 to 5.72%). The chemical extraction of oil, although more efficient than the mechanical one, presented higher levels of acidity and peroxide. The content of fibers in neutral detergent and crude protein of the pie decreased significantly for dried grains with drying air temperature above 40 °C.

Abstract:

Sugar palm (Arenga pinnata) starch and fibre are considered as a waste product of the agroindustry. The purpose of the current study is to determine the thermal, water barrier, and soil degradation properties of biodegradable plasticised sugar palm starch (PSPS) that contains sugar palm nanofibrillated celluloses (SP-NFCs) derived from sugar palm fibre. The bio-nanocomposites were fabricated by using the solution-casting method with the nanocellulose contents in the range of 0.1 wt.%–1.0 wt.%. The thermal stability, water resistance and degradation behaviour improved with increase in SP-NFCs content, due to high compatibility and strong inter-molecular hydrogen bonds formed between PSPS and SP-NFCs. PSPS/SP-NFCs bio-nanocomposites with 1.0 wt.% SP-NFCs content displayed the highest mechanical and thermal stability. Residue that was left during the TGA analysis increased as the SP-NFCs content was increased. Soil burial tests showed biodegradability resistance of the bio-nanocomposites. The following conclusions can be drawn from the present reinforcement study of SP-NFCs enhanced biodegradability, water barrier as well as thermal properties of starch polymer which extended the prospective application of environmentally-friendly polymer material. Potential applications for this eco-material are short product life cycles (plastic packaging and food container).

Abstract:

Introduction. During opencast mining, the development of mine workings in clays of Quaternary deposits is often accompanied by stability loss. As a rule, the reason for the development of geomechanical processes 46 "Izvestiya vysshikh uchebnykh zavedenii. Gornyi zhurnal". No. 3. 2021 ISSN 0536-1028 is the mismatch between the accepted geometry and physical-mechanical characteristics of soils. In case strength characteristics and moisture content are strongly related in the conditions of lacking water saturation sources, slopes remain stable for a long time. However, in the case of water saturation, soils change to plastic or liquid consistency, and the strength properties are reduced. In engineering practice, to prevent hazardous geomechanical processes, electrophysical methods are applied that make it possible to build the boundaries of soil moisture anomalies through electrical contrast. In the instances when the water-saturated strata occurrence depth and thickness is known from drilling and vertical electrical sounding data, electrical profiling makes it possible to promptly determine the variability of these characteristics of the anomaly. The authors proposed an algorithm of water-saturated strata thickness variability determination from the point of electrical profiling. Research aim is to predict the stability of the marginal rock mass in clays of Quaternary deposits, taking into account the effect of filtration reservoirs by combining engineering-geological databases and geophysical measurement results based on the 3D geological-geophysical model. Methodology includes the analysis of the engineering-geological databases and geophysical measurement results. Results. A 3D geological-geophysical model of the marginal rock mass with the boundaries of the watersaturated stratum was built from the results of the research to predict the stability of the marginal rock mass’s actual position. Slope stability analysis established the following: at design sections О3у3–О5у5 after deformation, retaining forces exceed shearing forces significantly (safety factor) because the weight of the base wedge grows due to landslide masses; potential landslide hazard area is associated with the design section О1у1, which is due to smooth fall of the stability factor from 1.38 (section О2у2) to 1.06, close to ultimate. Conclusions. For the extension of the marginal rock physical-mechanical properties variation it is appropriate to apply the method of electrical prospecting (sounding and profiling) determining watersaturated areas by local negative anomalies of effective electrical resistivity and establishing the function of loose Quaternary deposits thickness variation by the inversion of electrical profiling graphs with the use of the least square procedure and the golden section method. If landslide hazard areas are vast, the variation of the stability factor design values, which were determined based on 3D geological-geophysical models, may possess the non-monotonic character with several extreme values and significant gradients. For that reason, it is appropriate to carry out computerized analysis with a cyclic extension of the most hazardous areas by the coordinate of the profile and the direction of the design section in a plan.

Tillage equipment operated under such conditions, must possess high permeability and strength, while providing acceptable quality. These requirements correspond to the most ploughs-rippers with disk working bodies. It uses both passive and active working bodies, which brings the first disc plows and heavy harrows, and the second milling tillage. On the basis of the spent constructive analysis of existing tools their classification by drive type (with an active mechanical drive, with an active hydraulic drive, with a passive drive), method of aggregation (rear-mounted mounted, mounted on lateral faces) and to type of the safety mechanism (spring, hydraulic, without safety locks) is resulted.The tools representing various constructive types are in more details considered. Given their technical characteristics: variants of aggregation, type of drive, quantity of working bodies, the width, the diameter of the disk working bodies, depth of processing, type of safety mechanism, weight. The short description of designs and appointment disk rippers is given.On each tool the critical analysis is carried out and conclusions are drawn on possibility of its application in conditions not cleared cuttings down. Based on the analysis formulated the main requirements to prospective disk rippers that will effectively carry out basic preparation of the soil in conditions not cleared cuttings down at height of stubs to 50 sm in various conditions of the Russian Federation.

Abstract:

Introduction. Interest in the study of weathering crusts arose at a time when geological engineers faced the problem of developing open pits formed by eluvial soils. However, the exact and detailed division of the weathering crusts into engineering-geological zones, especially when studying mineral deposits, is not given due attention even today. Therefore, in the course of prospecting, it is important to correctly determine weathering crust type and profile, and establish the possibility of changing the engineering and geological conditions when opening the rock mass by mine workings for further slope stability prediction of the designed mining structures. Research aim is to determine vertical engineering-geological zoning of the Malmyzhsky deposit weathering crusts (Svoboda area) and identify patterns in alluvial deposits physical and mechanical properties change, which define the safety of mine development. Methodology. A significant number of Russian and foreign scientists have considered the formation of weathering crusts from different positions. They established the geochemical zoning and engineeringgeological zoning of the weathering crusts. Results. The article describes the Svoboda area at the Malmyzhsky gold-copper-porphyry deposit. Engineering and geological zoning of the weathering crust section was carried out according to a set of features, including structural and textural features, mineral composition, physical and mechanical properties of rocks. Within it, three zones are identified at the Malmyzhsky field, the Svoboda area: IV – dispersed, III – litomarge, and II – clastic. Physical and mechanical properties of rock building up the considered weathering crust have been analyzed proving that change in geological conditions within even one zone of the Malmyzhsky gold-copper-porphyry deposit (Svoboda area) entails a change in the choice of projected pit wall angles.

Abstract:

This work details the investigation of the influence of organo-mineral supplementation on the production of secondary metabolites in in vitro-germinated Bromelia balansae Mez. The seeds were germinated in vitro and transplanted to standard soils to undergo organo-mineral supplementation. The fully-grown plants were subjected to qualitative phytopharmacological prospection; quantitative analysis of total phenols and flavonoids; as well as chemical profiling by mass spectrometry. The in vitro germination of B. balansae was successful, with a germination rate of 94.95 %, thereby equaling to “super seeds” reported in literature. Moreover, the organo-mineral supplementation enhances the production of secondary metabolites in both leaves and roots, what therefore leads to higher yield of total phenols and flavonoids. Furthermore, mass spectrometry analysis confirmed the results from phytopharmacological prospection, and allowed the detection of fragments of secondary metabolites from shikimate/polyketide/mevalonate pathways.

Abstract:

Problem statement. Mobile robots are of significant interest among scientists and designers during the last several decades. One of the prospective drives of such robots is based on pneumatically operated walking (stepping) system with no use of electric, heat, magnetic or other types of energy. This allows the use of pneumatically-driven robots in the cases when the use of other energy sources is prohibited (e.g., in some gaseous or fluid mediums). At the same time, the walking (stepping) type of moving increases the manoeuvrability and cross-country capability of the mobile robot, and decreases the harmful effect of its interaction with the supporting surface (e.g., the fertile soil surface) in comparison with wheeled or caterpillar drives. Purpose. The main purpose of this research consists in substantiation of structure and parameters of pneumatic system of four-degree-of-freedom mobile robot with orthogonal walking drive and turning mechanism. Methodology. The research is carried out using the basic laws and principles of mechanics, pneumatics and automation. The numerical experiment is conducted in MathCAD software; the computer simulation of the robot’s motion is performed using SolidWorks software; the modelling of the pneumatic system operation is carried out in Festo FluidSim Pneumatic software. Findings (results) and originality (novelty). The improved structure of the mobile robot with orthogonal walking drive and turning mechanism is proposed. The pneumatically operated system ensuring the robot’s curvilinear motion is substantiated. Practical value. The proposed design of walking robot can be used while designing industrial (production) prototypes of mobile robotic systems for performing various activities in the environments that are not suitable for using electric power or other types of energy sources. Scopes of further investigations. While carrying out further investigations, it is necessary to design the devices for changing motion speed of the robot and the height of lifting of its feet.

Abstract:

Summary The purpose of this paper is to analyse the introduction of certain plant species such as pot marigolds (Calendula officinalis L.) into neglected and predominantly urban spaces in the Republic of Serbia. The research was based on the results obtained in a two-year experiment conducted in the vicinity of the Novi Sad-Backa Palanka road. The primary objective of the experiment was to examine the behaviour of pot marigolds in poor-quality and neglected soils, with minimum cultural practices, in order to obtain novel plants in such adverse environments, which could be subsequently marketed in Serbia. The experiment commenced in 2014 by planting pot marigolds in plots previously cleared of weeds by mechanical tilling. In the spring of 2015, pot marigold seedlings, i.e. the first generation of plants obtained from the plots created in 2014, were planted in weed-free plots. The measurements were performed in three replicates from 10 October to 10 December 2015 in order to determine the number of volunteer plants, which could be further improved in nursery production and subsequently marketed in Serbia. The results obtained indubitably indicate that this and prospective studies exert positive ecological, agricultural and economic effects on a vast range of potential users.

Abstract:

The objects of ?Neolithic plastic art? from Belica, made from baked clay, stone and bone, have been arriving at the Regional Museum in Jagodina since 1991. These are accidental finds which never caught the attention of experts, even though one of them, a figurine from black rock which arrived at the museum in 1992, has been a part of a permanent exhibition. Almost two decades after its arrival at the museum, the archaeologist Dr Milorad Stojic would place it among the most substantial finds of Neolithic figural plastic, identifying it as the Proto-Starcevo culture, dated to 6000 years BC and named it the ?Great Mother?, linking her to the Neolithic cult of fertility (Stojic 2011, 344) Asignificantly greater number of objects from Belica since 2001, first as accidental finds by Zivota Milanovic, an associate of the Regional Museum in Jagodina, arrived to Dr Milorad Stojic who undertook a one-day protective intervention at the site of Pojate-Pojilo in Belica village, the exact area from which previously collected finds originated. Ashort excavation, which was ?less than two full hours of work? (according to the Report of the excavation), was carried out in January 2002. On that occasion a pit, which was only 10 cm deep and located on the surface of the village dirt road, was investigated (fig. 1). The excavation, together with the appropriate technical documentation, has not yet been published. The discovered pit was located in the middle of the dirt road which was used by agricultural machinery and which had, on several occasions prior to the exploration in 2002, been repaired by heavy construction machinery. In the years following 2003, two more groups of finds of art objects from the Early Neolithic were discovered in Belica and Lozovik (Stojic 2008, 73). In the Livade site in Belica, which is 500 m from the site of Pojate-Pojilo, four objects made of stone were found. In Lozovik, in the Repuska site, three figurines made of deer bone were discovered. In both sites the finds of the aforementioned objects were followed, according to the author, by finds of Proto- Starcevo ceramics. More detailed descriptions of the locations, conditions of discovery and subsequent finds do not exist. In August 2003, within the usual activities of the project Permanent Archaeological Workshop - Central Pomoravlje in Neolithisation of South East Europe, under the supervision of S. Peric, in the Pojate-Pojilo site in Belica, some sondage excavation was performed. One of the reasons this precise location was chosen for exploration was that stone plastic finds are attributed to it, for which there are no suitable analogies within the Middle or Late Neolithic Starcevo culture. Two sondages of 5 x 5 m (fig. 2) were explored. The results of the exploration were modest, which was in accordance with expectations based on several visits made to all three Neolithic sites in Belica village. One smaller Late Neolithic settlement from the Proto-Starcevo period existed on this location. In conclusion, it should be mentioned that none of the finds from this exploration could be connected to the accidental finds of stone plastic from the village road even though, during the time of the exploration, daily surface prospecting of this and the two neighbouring Neolithic sites was carried out. A detailed inspection of the profile, which is cut by the village road where it is believed that there was a Neolithic pit of about 1m in depth, was also performed. The village road, as we originally found it, worn out and uneven, with around twenty centimetre deep tracks made by tractor wheels and with no clods of turf on it, didn?t leave the impression that an only 10 cm deep bottom of a pit could be preserved (fig. 3). The objects discovered in the pit explored in 2002 include: 60 stone, 9 ceramic and 11 bone and deer horn objects. Within this number are also included the objects found in 2001 in the immediate vicinity of the pit (Stojic 2011, 341-342). The most numerous are anthropomorphic figurines, and besides them there are several examples of sacrificial altars, conical objects (pintadera), axe figurines and one rectangular plate. Ceramic figurines from Belica, which in their form resemble the Palaeolithic Venus figurines, were made from insufficiently refined soil, which is a practice completely opposite to the one noticed on the figurines from the other Neolithic sites of the Central Balkans. The soil from which they were made resembles that used for making rough ceramics or for building houses (daub). Therefore, our doubt that we are dealing here with figurines which resulted from the mechanical treatment of already baked soil, and not with objects which got their final form in raw clay prior to baking, is not surprising. The same is true with bone objects in which subsequent work is visible on a piece of bone which remained in the ground for a number of centuries. By courtesy of Dr Milorad Stojic, an archaeologist to whom Zivota Milanovic, the sole discoverer of these objects, was bringing finds from Belica, and who was digging the pit with the group of art objects finds, the authors of this paper had an opportunity to thoroughly microscopically examine several stone and bone objects from Belica (the Pojate-Pojilo and Livade sites) and from Lozovik (the Repuska site). Specifically, we are talking about five stone and four bone objects (fig. 4). The examination of traces of the treatment on the surface of these objects clearly showed that we are dealing with objects which had been mechanically treated by grinding tools spinning at a large number of rotations per minute. The results of this kind of treatment are fine, narrow, uninterrupted parallel grooves (fig. 5-10). After manual treatment with a grindstone of natural sandstone or by using only sand, only short grooves, which are significantly wider and not perfectly parallel, remain (fig. 11). With bone objects the situation is slightly different. Bones from the archaeological stratum were used, on which a subsequent treatment was performed which removed the darker coloured patina. Microscopic evidence of the working of the bone also shows the use of a grinding tool spinning at a large number of rotations (fig. 9-10). The case of the ?Serpentine figurine? is particularly interesting. On a simply crafted awl, which can be dated to the Neolithic period and beyond, a spirally carved embellishment was added (fig. 13). The difference in colour between the spiral detail and the rest of the awl indicates a large time interval between the making of the awl and the addition of the decoration. A fortunate circumstance in the story about the ?Neolithic art objects? from Belica is that they have not been accepted in Serbian archaeology. If we exclude the works of M. Stojic, the finds from Belica, glorified for their beauty, symbolism and originality, have not yet found their place in archaeological literature. There are no texts which even mention them as analogies for some other cult or art creations from the Neolithic. For this reason, this critical approach also happened at the right moment. If Serbian archaeology had not made any comments about the finds from Belica, for which there is some doubt as to whether they actually are of Neolithic origin, perhaps the damage caused by it would have been deeper and more noticeable. The question as to whether we could then talk about the Serbian ?Neolithic deception from Belica? is one whose answer the authors of this paper did not want to wait for with their arms folded.

Abstract:

Vast areas in the Arctic are faced with widespread threats ranging from gas and oildevelopment to tourism (Sippola et al., 1995; Crawford, 1997; Forbes et al., 2001). EastEuropean and West Siberian parts of Russian Arctic have important resources of gas andoil and, thus, experience intensive mechanical impacts. By the mid-1990s, off-roadtransportation connected with geological prospecting had already resulted in severedamage of parts of the Y amal Peninsula. Y amal ecosystems are characterised by extremevulnerability and low restoration potential. The rate and patterns of their natural recoverydepend on the severity of the disturbance, latitudinal position and habitat type. Thoughonly 4.5% of the local flora species in surroundings of Bovanenkovo gas field (centralYamal) can be considered as active colonizers, natural recovery is conducted only byaboriginal species. Adventitious element, wh ich is common at disturbed sites in theBoreal zone, was not found. The main problem of recultivation in the northern parts ofY amal is the absence of appropriate seed material. The planted seeds of southern grassesget completely extinct after 1 or 2 winters. Only local species (Deschampsia glauca, Poaalpigena, Arctagrostis latifolia, Calamagrostis neglecta) should be used. The study ofnatural recovery has showed that recommended sets of species should be site specific.Along with grasses, sowing mixtures should include sedges and forbs (different sets forsandy and loam soils). Transplanting seedlings or vegetatively reproduced young plants(especially for sedges) give good survival results. Use of willow cuttings is verypromising but appropriate species (Salix lanata, S. reptans) should be chosen.

Therefore, the problem of rational use of natural resources, in particular protection of early spring plant species is very important. However, literary sources analysis only reveals data on the biology of species of this genus. The present research,conducted in the spring of 2017-2019, focuses on anatomical and morphological features of two Altai species: Gagealutea and Gagea minima; these features were studied, clarified and confirmed by drawings and photographs. The anatomical structure of the stem and leaf blade was studied in detail. The obtained research results will prove useful for studies of medicinal raw materials and honey plants. The aforementioned species are similar in morphological features, yet G. minima issmaller in size, and its shoots appear earlier than those of other species Keywords: Flora,gageas,Altai species,vegetative organs., Refference: I.

Voropaeva,Viktoriay A. Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

View | Download DEVELOPMENT AND TESTING OF AUTONOMOUS PORTABLE SEISMOMETER DESIGNED FOR USE AT ULTRALOW TEMPERATURES IN ARCTIC ENVIRONMENT Authors: Mikhail A. Abaturov,Yuriy V. Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

View | Download COMPARATIVE ANALYSIS OF RESULTS OF TREATMENT OF PATIENTS WITH FOOT PATHOLOGY WHO UNDERWENT WEIL OPEN OSTEOTOMY BY CLASSICAL METHOD AND WITHOUT STEOSYNTHESIS Authors: Yuriy V. Lartsev,Dmitrii A. Rasputin,Sergey D. Zuev-Ratnikov,Pavel V.Ryzhov,Dmitry S. Kudashev,Anton A. Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Shulunova,Alexander I.Sidelnikov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00045 Abstract: Purpose.To determine the quantitative echogenicity indicators (and their ratio) of the layers of stomach and small intestine wall in healthy dogs. Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

Tsvetkov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00047 Abstract: The present study of comparison methods based on the triadic model introduces the following concepts: the relation of comparability and the relation of comparison, and object comparison and attributive comparison. The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
