The results of numerical modeling of frequency dependence of permafrost surface impedance in a band of 1 Hz to 1000 MHz are shown for typical geoelectric sections (GESs) of Central Yakutia. Particular qualities of frequency dependence are represented by oscillation values in a wide frequency band. The role the bias and conduction currents play is marked. Two main bilayer models of permafrost are discussed: weak-inductive and strong-inductive models. Additional three-six layer models are considered along with indication of their particular qualities and conformity with natural sections. An example of models’ comparison with radio impedance sounding data is given. One marks the significance the phase curves of radio impedance sounding possess when used for determination of GES type under condition of approximate automatic interpretation.

The use of hydrostatic steerage in agricultural and construction vehicles shows that, compared to traditional hydromechanical steerage, it has better balance and no steering wheels vibrations. But in certain environments, these automobiles have to work in severe conditions and the steering breaks down rather quickly. There can be multiple reasons for this – dirt, wear, excessive turn effort. The analysis of defects of the XY 145 0/1 hydraulic steers has demonstrated that 100% of breakdowns are caused by the wear of the slide valve-housing pair, i.e. this contact is limitative. Therefore, complete wear of these parts lead to the situation when turning the vehicle requires the effort exceeding normal. To find out how to increase durability of the valve-housing pair, we conducted a research of its stress-strain state. The strains in the contact can be studied with the help of the finite-element method which allows high-precision modeling of any components and mechanisms in operation. As a result, we generated a finite-element mesh with the minimal, average and maximal pressure values, transitions and deformations in elements; pressure values were presented as a graphical file with a diagram. The model of the strain state of hydraulic steer XY-145 slide valve-housing contact can be used in selecting the materials which, applied to the worn surfaces, will increase the general durability of hydraulic steers.

The purpose of this study was to explore the possibility ofboth soapwort (S. officinalis L.) and bouncing Bet,or double‑flowered soapwort (var.floreplenе hort.) cultivation in the soil and climate conditions of PrimorskyKrai (Russia); to study the effects ofS. officinalis vegetation time on the composition and micellar properties of saponin root extracts for their use as highly effective natural surfactants. The dynamics of the saponin accumulation in the root, depending on the cultivation time, is studied. The values of the surface tension and the critical micelle concentration indicators of saponins and water root extracts are established for both S. officinalis types and different vegetation time.The influence of different technological factors on the micellar parameters of saponin roots for both S. officinalis types is investigated.It was found that highersaponin parameters of the bouncing Bet S. officinalis type allows recommending it as a highly promising source of natural surfactants, on a pair with commercial Quillajasaponin by its micellar parameters.The established pattern in hemolytic activity changes of the extracts from the vegetative stage S. officinalis roots allowsexpanding the sphere of their application.

Elena N. Volkova,Ekaterina A. Vlasenko,




The article presents new methodological methods for interpreting geological and geophysical data with the aim of justifying the search for oil and gas in the inner regions of Cis-Caspian depression and confirming the hypothesis of uplifted foundation blocks and large drillable subsalt elevations. For the territory of Cis-Caspian depression, new schemes of composite magnetic field strength and gravity field anomalies maps were obtained at different transformation parameters, taking into account qualitative zoning of the territory according to sign ratios. The transformed parameters are obtained by analytic continuation into the upper half-space to a height of 5-50 km by calculating the residual values and difference in the geophysical values between the altitude levels, i.e. by obtaining interval transformants that narrowed the range of the possible interval of the geological section, in which the appearance of anomalous-forming masses in the subsalt paleozoic can be expected. The observed fields were represented in the form of numerical matrices covering theentire territory of Cis-Caspian depression with 120*100 dimensions of elements for maps of 1: 1 000000 scales. A total of 40 schemes of geophysical parameters were generated. In the central part, the transformations allowed identifying large, intense anomalies associated with the morphology of the subsalt bed surface. Gravity steps, which limit large anomalies, testify to the steep slopes of structural elements. This isthe possible zones of transition from shallow-water conditions to deep-water ones. The oil and gas prospects of the geological situation are determined by a combination of negative magnetic and positive gravitational fields observed in theincreasingly thick areas of carbonate rocks caused by organogenic structures of basinal, flankand shelftype on the slopes of major elevations. As a result of processing and interpretation, in Hobdin high area the author predicts the existence of an elevated relative to the depression part zone within which a possible socle for further growth of large carbonate structures such as Karachaganak is located. The zone with the same signs is also registered in the western part of the Central Caspian depression in the region of Aralsor gravity high.

Tatyana V. Kushnareva,




The 1999–2012 monitoring of epizootic situation registered active natural foci of the Hantaan, Amur, Hokkaido and Vladivostok hantaviruses, the first two of which cause hemorrhagic fever with renal syndrome (HFRS). The peculiar features of the forest and forest–steppe natural foci of hantaviruses were revealed. In the southwest parts of the region in the forest–steppe foci, Apodemusagrarius and Microtusfortis infected with the Hantaan and Vladivostok hantaviruses respectively were found; in the forest foci of the central and northeast parts, Apodemuspeninsulae and Myodesrufocanus infected with the Amur and Hokkaido viruses were registered. In all phases of the epizootic cycle, the indicators of number and contamination in mice populations were much higher as compared with vole populations. HFRS incidence in the forest–steppe and forest focal territories correlated with the activity of the Hantaan and Amur virus foci respectively. The results of the monitoring allowed us to determine the threshold indicators of number and contamination of small mammals (SM) at which aggravation of HFSR epidemic situation occurs in the forest–steppe and forest foci of hantaviruses. In case of increased epizootic activity in the Apodemus mice populations, it is necessary to carry out a complex of preventive measures against HFRS.

The urgency of the problem under consideration in modern conditions is determined by the leading influence of road transport in polluting the components of the surrounding environment. Previous scientific developments focus mainly on the assessment of the effect of gaseous emissions; an estimate of the intensity of heavy metal contamination in the form of aerosols is practically absent. The article is aimed at developing a method for assessing the contamination of roadside areas with heavy metals contained in emissions and waste from moving vehicles. The leading method in the study of this problem was the mathematical model and methodology for estimating the aerosol contamination of the atmosphere by heavy metals on the basis of experimental studies of atmospheric pollution and pollution of soils at 240 locations along the profiles on the M-4 autoroute. The total number of samples analyzed was 840 units. The mathematical model took into account the meteorological indicators and the integral indicator of soil contamination atthe depth of 1m. It was revealed that the main pollution is observed at a distance of up to 10 m from the roadway edge, which confirms the developed model and methodology. Copper, lead, zinc, and cadmium were singled out as the main pollutants.The scale of the index of environmental risk categories based on the specified total contamination index of the roadside area was developed. Based on the research results it was recommended to locate economic activities at distances more than 25 m from the roadway edge. The materials of the article can be useful for scientists in the field of environmental protection, as well as for environmental organizations that make decisions on the feasibility of practical and economic development of first-order highway roadside areas

Today, ongoing improvement of business processesis required to enhance the efficiency and competitiveness of the enterprisedue to the high volatility of the market, increased competition, and scientific and technological progress. This article is devoted to challenges facing effective change management in industrial enterprises and aims to devise a methodology for effective change management. The significance of this research topic lies in the fact that there is still insufficient discussion of effective change management in industrial enterprises, especially those in which outsourcing services are diverted or are being diverted from the energy, automation, mechanics, and IT departments. As of now, change management only starts to shape itself into a distinct area of research and one of the leading approaches to its study is evaluating the enterprise activity on the basis of the Shewhart-Deming cycle. This paper examines different levels and approaches to change management. A methodology is developed to create effective change management aimed at helping calculate the economic efficiency of projects. Popular economic indicators were systemized and evaluated in terms of their applicability from a regional perspective. Training of specialists who will work in these changing conditions is another focus of attention.

The aim of the studies was to conduct an environmental assessment of heavy metals (Cr, Ni) content in agrocenoses of the forest-steppe zone in the southwestern part of the Central ChernozemicZone(CCZ). It was established in the course of the research, that the average gross content of nickel in the arable layer of chernozemic soil in the leached CCZforest-steppe zone was 24.9;average content ofchromiumwas 21.0 mg/kg.With an increase of the soil profile depth the gross content of heavy metals did not change. The average content of nickel and chromium mobile forms in the 0-20 cm layer was 0.63 and 0.44 mg/kg, respectively. The content of nickel mobile forms in the 81-100 cm layer was lower than in the arable layer; there was no significant change in the content of chromium with the depth of the soil profile. MPC surplus for heavy metals mobile formswas not observed. The biological absorption factor for the main and by-products of the studied agricultural crops for nickel was in the range of 0.20-3.98; and 0.15-0.88 for chromium. The main sources of the studied elements entering the agrocenoses of the Belgorod region were organic fertilizers. The application rate of organic fertilizers on average for the years of 2010-2013 was 3.95 t/ha, wherein 86.5% of nickel and 81.0% of chromium were supplied to agrocenoses.

The purpose of this study is to conduct an environmental assessment of zinc, copper and cobalt content in the agrocoenosisof forest-steppe zone of the Central Chernozemregions(CCRs) of Russia.During the investigations it was revealed that the average gross content of zinc is 37.1.copper - 13.8.cobalt - 7.74 mg/kg in arable soils ofthe leached chernozem of forest-steppe zone of the CCRs. With increasing depth of the soil profile, the gross content of zinc and copper is significantly reduced, and cobalt gross content is not changed. According to the results of a continuous survey conducted in 2010-2014, it was found that 99.2% of the arable soils of Belgorod region are characterized by low provision of mobile forms of zinc, 96.8% of copper, and 94.3% of cobalt. According to the results of local monitoring, it was revealed that the content of mobile forms of cobalt and copper in the 81-100 cm layer is significantly lower than in the arable soil, and the zinc content does not change significantly. The exceeding MPC for mobile forms of trace elements was not observed.For the main products of winter wheat, pea, soybean, sunflower and corn, the biological absorption factors of zinc were in the range of 2.9-42.2, copper - 4.36-42.0, cobalt - 0.38-2.7,and for the by-products - 1.1-6.3, 1.8-4.63, and 0.16-1.54, respectively. The main source of trace elements entering the agrocoenosis of Belgorod region are organic fertilizers.

Study of improving the reliability and lifetime of bladed pumps is now of great importance. In this context, the key objective is to reduce the hydrodynamic vibration of screw-centrifugal pumps caused by pressure pulsations in the pump outlet casing . Due to the flow stepwisenonuniformityat the impeller outlet, pressure pulsations emerge at the rotor blades passing frequency and its harmonics. These vibrations cause a dynamic load on the components of pump body causing its vibration, so the calculation of the pressure pulsations amplitude in the screw-centrifugal pump at the early stage of the design is a relevant task. When defining pressure pulsations generated by the three-dimensional vortex flow of the screw-centrifugal pump their dual nature should be considered. The heterogeneous distribution of the flow parameters at the outlet of the centrifugal impeller generates acoustic disturbances that are propagated at the speed of sound in the operating fluid. At the same time, there are vortex disturbances that are convected by the main flow. Vortex oscillations of the main flow parameters is called "pseudosound" or the vortex mode. This paper develops a three-dimensional acoustic-vortex method of calculating pressure pulsation, which provides the ability to determine the amplitude of acoustic mode. It shows the derivation of the acoustic and vortex equations and the calculation example of the pressure pulsations amplitude at the screw-centrifugal pump outlet with different guide channel design. It shows the ability of modeling the combinationcomponents in the spectrum of pressure pulsations.
