Published: May 2019

In the study of Quaternary deposits of the Crimea selected two phases. In the first stage (since the late XIX century to the sixties of XX century) stratigraphic description of the Quaternary strata was based on the allocation of terraced complexes (a marine terraces - in the coastal part and synchronous them alluvial ones - in continental part of the Crimean peninsula). In the second stage description of the Quaternary deposits is made on the basis of their climatic and stratigraphic dissection under the leading role of the loess-soil formation structure. The basis for stratigraphic subdivision of Quaternary deposits of the Crimea was the structure of the valleys of the paleo-Dnieper and paleo-Dniester. It is shown that the nonlinear, reversible character of Black sea level changes that took place in the Quaternary can be broken a rule “the lower the hypsometrically level of the terrace is, the younger this terrace is”.

In this paper the temperature treatment impact on Bazhenov formation core samples are shown. Impact was performed by pyrolysis in a temperature range of 300-480 °C and in the closed autoclave in the presence of water at reservoir pressure. It is shown that as a result of thermal exposure at 400 °C pyrolytic peak S2 is reduced by 90-95% and generation potential of rocks almost completely implemented. The microtomographic samples studies combined with scanning electron microscopy allowed to establish the dependence of permeability and porosity of the rocks. It demonstrated that even at 350 °C the fracture system formed in core samples also the porosity and permeability due to impact may increase from several times to several ten times. The results will allow for a more accurate simulation of enhanced oil recovery treatment on Bazhenov formation rocks to increase oil recovery.

Published: May 2019

The experiments on studying leaching of trace elements (Li, Rb, Cs, Sr, Ba, V, Mn, Fe, Co, Ni, Cu, Tl, Y, La, Ce, Th, U) from unaltered ash of the Karymsky volcano (Kamchatka) under its interaction with 0.01 M solutions of oxalic, salicylic, tartaric, citric, and acetic acids at the different solid/liquid phases mass ratio were lead. Based on the obtained data it is drawn a conclusion that mobilization of trace elements occurs mainly as a result of demolition of crystal structure of rock-forming minerals, as well as (in case of oxalic acids) at reduction of Fe(III) and Mn(IV) oxyhydroxides to soluble Fe(II) and Mn(II) compounds. Organic complexes formation increases of the metals stability in solution and provides a possibility of achievement of much higher values of the dissolved forms concentration than for the lack of organic ligands.

Published: May 2019

A theoretical evaluation of the scale effect in dispersed soils is considered in the engineering-geological study of various physical and physical-mechanical properties that depend on the structural inhomogeneity of the soil. Concepts and new quantitative indicators are proposed to evaluate the manifestation of the scale effect in disperse soils in relation to physical and physical-mechanical properties. A classification of structural heterogeneitysin disperse soils that affect the scale effect in them has been developed. The method for analyzing the scale effect in dispersed soils is described on the basis of the superposition principle. The theoretical model of registration of the scale effect in disperse soils is substantiated at an engineering-geological evaluation of various physical and physical-mechanical properties.

Authors: Muromets N. N. , Samartsev V. N. , Khakimova A. A. , Vasilesvky P. Y.
Published: May 2019

A regional model of catchment of small river (catchment area is about1000 km2) is discussed. Model was developed to evaluate possible influence of hypothetical groundwater intake on river flow. The model was calibrated to measured groundwater heads and river flows. Geophysical and hydrometric survey allowed to characterize a heterogeneity of riverbed along the channel. River flow reduction, calculated on model with riverbed heterogeneity is greater by 25% compared to that calculated without heterogeneity. Thus it is shown that accounting for riverbed heterogeneity is advisable for more reliable prediction of impact of water intakes on environment.

Authors: Tevelev Al. V. , Prudnikov I. A. , Tevelev Ark. V. , Khotylev A. O. , Volodina E. A.
Published: May 2019

In this work we reported the structural features and mechanism of the formation of the Simskaya low of the Uralian foreland basin, besides the Karatau-Suleyman block as a whole. This block has the shape of a wedge, so with a general latitudinal compression, it experienced lateral extrusion to the north along the conjugated shear zones. This factor determined the local situation of meridional compression and latitudinal tension. In the central part of the block, the latitudinal stretching was compensated for by gradual deflection, which led to the formation of the Simskaya low.

Authors: Shevnin V. A.
Published: May 2019

Diffusion and adsorption (DA) potentials are frequently the sources of self-potential anomalies, but they not arouse such practical interest as anomalies of red-ox and filtration origin. DA anomalies can be found everywhere and geophysicists sometimes make mistakes considering DA anomalies as examples of filtration anomalies. Identification of DA anomalies is based on correlation of SP and apparent resistivity values along the same profiles. At MSU students geophysical practice in Kaluga region we obtained profiles with SP and resistivity anomalies with good correlation between them. That fact allows consider such SP anomalies as a result of DA processes.

Published: May 2019

The paper presents for the first time a reliable dataset on formation water salinity and salt composition for tight shale formations of Bazhenov, Achimov and Georgiev suites. The data were obtained in the result of laboratory analysis of aqueous extracts from rock samples before and after its hydrocarbon extraction (cleaning). Based on the experimental data a thermodynamic modeling of solution-mineral equilibrium was performed followed by Na/Cl, Ca/SO4, Mg/SO4, Ca/Cl, Ca/HCO3, Fe/SO4 correlation analysis. The results shown that concentrations of certain macro-components, including Ca, Mg, Fe, hydrocarbonate and sulfate ion in pore solutions cannot be reliably determined using aqueous extract data. At the same time a reliable estimate nominal salinity of formation water could be provided using the obtained data. The paper concludes that a reliable study of macro-components’ chemical composition in formation waters of tight shale formations requires laboratory analysis of non-extracted rock core samples with maximal preservation of water content.

Published: May 2019

Coalbed methane (CBM) is a new clean and unconventional energy that has broad space for development. In Qinshui basin, CBM reserves reach 3,97·1012m3, which is 10,8% of the total resource in China. Compared to the main coal basins of USA, Australia, Canada and Russia, coal seams in Qinshui basin have the characteristics of high metamorphism, high gas content, low porosity, low permeability and low reservoir pressure. Therefore, effective stimulation treatments must be used in Qinshui basin to realize industrial exploitation of CBM. At present, vertical wells with hydraulic fracturing are dominated in Qinshui basin. In addition, injection CO2, electric pulse, multi-stage fracturing and other technologies are also applied to the CBM exploitation.

Published: May 2019

This article provides detailed information about the geological setting and the chemical composition of some thermal springs (Garm-Chashma, Firuza-MGU, Tandykul, Obigarm, Khojaоbigarm) located within the Pamirs and the Tien Shan mountain systems. This is the first report describing the micro components data for investigated springs obtained by the ICP-MS method. The calculated ratios of B:Cl, B:Br and Li:Rb:Cs allow to define the genesis of the studied thermal springs. New data on the contents of 18O and D indicate that the studied thermal waters are most likely meteoric, while a slight drift from the meteoric water line is the result of isotope fractionation in water-rock-gas processes. The estimated subsurface temperatures for these thermal waters vary from 136 °C to 240 °C based on the K:Na geothermometer.

Published: May 2019

We present the results of studies of the internal structure of synthetic malachite aggregates obtained by two methods: in an open flowing (VNIISIMS, Mingeo USSR, Aleksandrov) and closed evaporation-recirculation (IEM RAS, Chernogolovka) systems. The internal structure and chemical composition of the malachite samples were studied using a Tescan Vega II XMU scanning microscope with an energy dissipation spectrometer (EDS) of INCA Energy 450. The results of the studies showed significant differences in the internal structure of malachite obtained by different methods. These differences are displayed mainly in the structure of malachite aggregates, and are due to different mechanisms of transport and deposition during malachite dissolution and crystallization.

In exploring how to achieve this goal, educators are turning their attention and resources increasingly to the priority of professional development. Teacher mentoring programs are now perceived as an effective staff development approach for beginning teachers. By establishing teacher mentoring programs, the district serves two important purposes: novice teachers are given a strong start at the beginning of their careers, and experienced classroom teachers serving as mentors receive recognition and incentives (Little and Nelson, 1990).

Researchers believe that mentoring can be a valuable process in educational reform for beginning teachers as well as veteran teachers (Ganser, 1996). Supporting beginning teachers at the outset contributes to retention of new teachers in the school system. Formalizing the mentor role for experienced teachers creates another niche in the career ladder for teachers and contributes to the professionalism of education.

Effective organizations place a premium on talent when selecting, developing, and advancing their workforce. States and school districts tend to approach teachers from a one-size-fits-all perspective that inhibits efficient and productive workforce management. Organizing the teacher workforce for efficiency and productivity can best be done with careful management of individual talent and careers. Child development is a field of study concerned with the growth and well-being of children and young adults. The present practice of professional and career development too frequently fails to differentiate developmental paths for individual teachers. Not only is there a tendency to neglect identifying highly effective teachers for the purpose of retaining, advancing, and placing them in assignments that maximize the impact that they have on student learning, there is also a similar tendency to neglect identification of under-performers.

The use of green marine seaweed Ulva spp. as foods, feed supplements, and functional ingredients has gained increasing interest. Microwave-assisted extraction technology was employed to improve the extraction yield and composition of Ulva pertusa polysaccharides. The antioxidant activity of ulvan was also evaluated. The impacts of four independent variables, i.e., extraction time (X1, 30 to 60 min), power (X2, 500 to 700 W), water-to-raw-material ratio (X3, 40 to 70), and pH (X4, 5 to 7) were evaluated. The chemical structure of different polysaccharides fractions was investigated via FT-IR and the determination of their antioxidant activities. A response surface methodology based on a Box–Behnken design (BBD) was used to optimize the extraction conditions as follows: extraction time of 43.63 min, power level of 600 W, water-to-raw-material ratio of 55.45, pH of 6.57, and maximum yield of 41.91%, with a desired value of 0.381. Ulvan exerted a strong antioxidant effect against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and showed reducing power in vitro. Ulvan protected RAW 264.7 cells against H2O2-induced oxidative stress by upregulating the expression and enhancing the activity of oxidative enzymes such as superoxide dismutase (SOD) and superoxide dismutase (CAT). The results suggest that the polysaccharides from U. pertusa might be promising bioactive compounds for commercial use.

Coal-fired power stations are one of the primary sources of power generation in the world. This will produce considerable amounts of fly ash from these power stations each year. To highlight the potential environmental hazards of these materials, this study is carried out to evaluate the characterization of fly ashes produced in thermal power plants in northern Vietnam. Fly ash was firstly fractionated according to size, and the fractions were characterized. Then, each of these fractions was analyzed with regard to their mineralogical features, morphological and physicochemical properties. The analytical results indicate a striking difference in terms of the characteristics of particles. It was found that magnetic fractions are composed of magnetite hematite and, to a lower rate, mullite, and quartz. Chemical analyses indicate that the non-magnetic components mainly consist of quartz and mullite as their primary mineral phases. As the main conclusion of this research, it is found that the magnetic and non-magnetic components differ in terms of shape, carbon content and mineralogical composition. In addition, it was found that magnetic components can be characterized as more spheroidal components compared to non-magnetic ones. This comprehensive characterization not only offers a certain guideline regarding the uses of different ash fractions but it will also provide valuable information on this common combustion process.

Porous hydroxyapatite (HA) artificial bone scaffolds were prepared via the freeze-gel casting process in order to improve their mechanical strengths. As a porogen, various volumes of poly (methyl methacrylate) (PMMA) powders were added to obtain high porosity, such as in cancellous bone. After fabrication, the porous and mechanical properties of the scaffolds were examined. The HA60 scaffold, with a porosity over 80%, had proper compressive strength and modulus and satisfied the range of properties of cancellous bone. Moreover, it was found that the investigated mechanical properties were affected by the scaffolds’ porosity. However, a section was found where the compressive strength was high despite the increase in the porosity. Specifically, HA30 had a porosity of 62.9% and a compressive strength of 1.73 MPa, whereas the values for HA60 were 81.9% and 3.23 MPa, respectively. The results indicate that there are factors that can preserve the mechanical properties even if the porosity of the scaffold increases. Therefore, in this study, various parameters affecting the porous and mechanical properties of the scaffolds during the manufacturing process were analyzed. It is expected that the improvement in the mechanical properties of the artificial bone scaffold having a high porosity can be applied to tissue engineering.

Published: May 2019

A pilot-scale six-compartment hybrid anaerobic baffled reactor (HABR) with effective volume of 18 m3 was used to treat dyeing wastewater. The HABR system was able to treat the wastewater efficiently after FeSO4 pretreatment, as indicated by removal efficiencies of 33.7% for chemical oxygen demand (COD), 39.9% for suspended solid (SS), and 22.5% for sulfate (SO42−) during steadily operational period. Gas chromatography–mass spectrometry (GC-MS) showed that the concentrations of alkanes, amides, organic acids, ketones, phenols, and esters were much lower in the effluent than those in the influent; many high-molecular-weight compounds such as cyclanes, quinolines, and phenols were successfully transformed to low-molecular-weight ones. As illustrated from the results of generalized grey relational analysis (GGRA), COD removal efficiency was more closely associated with flow rate, organic loading rate (OLR), water temperature, and influent SS among the whole selected possible factors. Based on the overall treating effectiveness and the GGRA study, the optimized operation strategy of the dyeing wastewater treatment by HABR was obtained as the hydraulic retention time (HRT) of 12 h for steady-state operation with an up-flow velocity of 1.7 m/h as well as OLR of 1.5–2.0 kg COD/(m3·d).

Hydrologic margins of wetlands are narrow, transient zones between inundated and dry areas. As water levels fluctuate, the dynamic hydrology at margins may impact wetland greenhouse gas (GHG) fluxes that are sensitive to soil saturation. The Prairie Pothole Region of North America consists of millions of seasonally-ponded wetlands that are ideal for studying hydrologic transition states. Using a long-term GHG database with biweekly flux measurements from 88 seasonal wetlands, we categorized each sample event into wet to wet (W→W), dry to wet (D→W), dry to dry (D→D), or wet to dry (W→D) hydrologic states based on the presence or absence of ponded water from the previous and current event. Fluxes of methane were 5-times lower in the D→W compared to W→W states, indicating a lag ‘ramp-up’ period following ponding. Nitrous oxide fluxes were highest in the W→D state and accounted for 20% of total emissions despite accounting for only 5.2% of wetland surface area during the growing season. Fluxes of carbon dioxide were unaffected by transitions, indicating a rapid acclimation to current conditions by respiring organisms. Results of this study highlight how seasonal drying and re-wetting impact GHGs and demonstrate the importance of hydrologic transitions on total wetland GHG balance.

Exposure to airborne particulate matter (PM) has been associated with the transcriptional up-regulation of pro-inflammatory mediators. However, the effect of PM on post-transcriptional regulation of pro-inflammatory mediators has not been fully explored. In this study, we examined the acute effect of organic extracts from urban PM, rural PM and diesel exhaust particles (DEP) on the post-transcriptional control of interleukin-6 (IL-6) and interleukin-8 (CXCL8) using a human bronchial epithelial cell line. Both PM and DEP extracts induced the release of IL-6 and CXCL8 after 24 h of exposure. Time-course experiments were conducted to examine changes in mRNA steady-state levels and half-lives. The steady-state levels of CXCL8 mRNA increase at 15 min on cells exposed to both PM and DEP extracts. Meanwhile only the urban extract induced significant increases of IL-6 mRNA levels at 15 min. Indirect measurements of IL-6 mRNA half-life showed a dramatic increase in cells exposed to the organic extracts. CXCL8 mRNA half-life increases in cells exposed to PM extracts and not DEP extract. Nuclear run-ons demonstrated that the urban PM and DEP extracts promoted an up-regulation in the transcription rate of CXCL8 at 15 min but not for IL-6. Urban and rural PM influences the post-transcriptional control of CXCL8.

An ensemble of regional climate change scenarios for the North Sea is validated and analyzed. Five Coupled Model Intercomparison Project Phase 5 (CMIP5) General Circulation Models (GCMs) using three different Representative Concentration Pathways (RCPs) have been downscaled with the coupled atmosphere–ice–ocean model RCA4-NEMO. Validation of sea surface temperature (SST) against different datasets suggests that the model results are well within the spread of observational datasets. The ensemble mean SST with a bias of less than 1 ∘ C is the solution that fits the observations best and underlines the importance of ensemble modeling. The exchange of momentum, heat, and freshwater between atmosphere and ocean in the regional, coupled model compares well with available datasets. The climatological seasonal cycles of these fluxes are within the 95% confidence limits of the datasets. Towards the end of the 21st century the projected North Sea SST increases by 1.5 ∘ C (RCP 2.6), 2 ∘ C (RCP 4.5), and 4 ∘ C (RCP 8.5), respectively. Under this change the North Sea develops a specific pattern of the climate change signal for the air–sea temperature difference and latent heat flux in the RCP 4.5 and 8.5 scenarios. In the RCP 8.5 scenario the amplitude of the spatial heat flux anomaly increases to 5 W/m 2 at the end of the century. Different hypotheses are discussed that could contribute to the spatially non-uniform change in air–sea interaction. The most likely cause for an increased latent heat loss in the central western North Sea is a drier atmosphere towards the end of the century. Drier air in the lee of the British Isles affects the balance of the surface heat budget of the North Sea. This effect is an example of how regional characteristics modulate global climate change. For climate change projections on regional scales it is important to resolve processes and feedbacks at regional scales.

A field aerosol measurement campaign as part of the Measurements of Urban, Marine and Biogenic Air (MUMBA) campaign was conducted between 16 January 2013 and 15 February 2013 in the coastal city of Wollongong, Australia. The objectives of this research were to study the occurrence frequency, characteristics and factors that influence new particle formation processes. Particle formation and growth events were observed from particle number size distribution data in the range of 14 nm–660 nm measured using a scanning particle mobility sizer (SMPS). Four weak Class I particle formation and growth event days were observed, which is equivalent to 13% of the total observation days. The events occurred during the day, starting after 8:30 Australian Eastern Standard time with an average duration of five hours. The events also appeared to be positively linked to the prevailing easterly to north easterly sea breezes that carry pollutants from sources in and around Sydney. This suggests that photochemical reactions and a combination of oceanic and anthropogenic air masses are among the factors that influenced these events.
