Identification of electrofacies on the basis of well logging to determine sedimentation environment of horizon JK[2] in Em-Egovskoe field (Western Siberia)

Well logging results are one of the ways to study the buried terrigenous rocks genesis. To ensure the most objective characterization of the rock and identification of electrofacies it is necessary to use a complex geological and geophysical survey. The comprehensive investigations of environmental conditions based on well logging have been performed for the horizon JK[2] of Tumenskoe formation in Em-Egovskoe area, Krasnoleninskoe field (Western Siberia). The defined electrofacies were compared with the results of earlier conducted granulometric and mineralogical analyses. The totality of research provided for a conclusion that the investigated sediments of horizon JK2 had been formed within the destructive tidal delta. Thus, objective facies prediction can only be ensured by analyzing core and well logging data comprehensively

Water Potential in Conditions of Soil Solution Phase Change and During the Year

The dynamics of the soil water potential and soil temperature at different depths during the year was studied. As the object of the investigation we took soddy-podzolic clay loamy weakly gleyed soils of Zelenogradskiy base of Soil Science Institute. The data of soil water and temperature were derived from the automated meteorologic station “VantagePro2”. In conditions of the sustainable state of the other components of the environment, we discovered sharp spasmodic increase of the soil water potential at the passing of temperature values to the range below zero, i.e., in conditions of the phase overpass of the soil solution. All of the types of soil water potential changes (slow and rapid, significant and insignificant) occur due to the changes (decrease or increase) of the water content and soil temperature. For the first time in our country the thermohydrophysical phenomenon of (thermodynamic process) of sharp (at 5-6 times) and rapid (practically immediate) increase of the water potential after the overpass of the temperature over zero from the area of positive values to the negative values is discovered and described. The knowledge of specificities of the dynamics of soil water potential due to the temperature will allow us to plan the terms and norms of watering

Anthropic factor influence on evolution of drained dernovo-podzolic soils of Upper Volga Lowland

Hydromorphic dernovo-podzolic soils, placed in Upper Volga Lowland (Tver region) are investigated. It is established reasons of land melioration effect decrease in Noblackland zone of Russian Federation. It is studied mineralization of drained flow in year season. It is determined factor complex on improvement drained soil production. It is recommended to build no only draining system, but also system with two-way soil water regime. If application of mineral fertilizers in soil norm N200P150K150 agrochemical indexes improve and yield oats increase in 3 once

SOME ASPECTS OF DIFFERENTIAL DIAGNOSTICS OF GIANT-CELL TUMOUR, OSTEOCYSTOMA AND OSTEOSARCOMA

The problems of timeliness and correctness of diagnostics of bone tumours, as well as therapeutic decision deserve the most careful consideration. The present research concerns the detection of criteria of differential diagnostics of giant-cell tumours, osteocystoma and osteosarcoma (according to the literary data). According to the literature the study of clinical and radiologic diagnostics, allowed to work out differential and diagnostic tables of signs and algorithms of diagnostics of giant-cell tumours, osteocystoma and osteosarcoma. It enabled to detect a therapeutic and diagnostic approach to patients with bone tumours

Synthesis of CuAl-LDHs by Co-Precipitation and Mechanochemical Methods and Selective Hydrogenation Catalysts Based on Them

The paper presents the results of the synthesis and study of CuAl layered double hydroxides (LDHs) as well as their application as catalysts for the selective hydrogenation of crotonaldehyde. Phase-homogeneous LDHs were obtained by co-precipitation and mechanochemical methods, and critical parameters ensuring the formation of the target product were identified. In the case of coprecipitation, the formation of LDH is most affected by the pH of the reaction medium and the CO32−/Al3+ ratio. The optimal CO32−/Al3+ ratio is ca. 0.5–0.8 and pH 9.5–10.0. When mechanochemical synthesis is used, at 500 m·s−2 and 60 min, it is possible to obtain a single-phase CuAl LDH, whereas at higher energies, LDH is destroyed. The mechanochemical method makes it possible not only to reduce the synthesis time and the amount of alkaline wash water but also to obtain more dispersed copper particles with a higher hydrogenating activity. The conversion of 2-butenal (T = 80 °C, P = 0.5 MPa, 180 min, ethanol) for this sample was 99.9%, in contrast to 50.5% for the catalyst obtained by co-precipitation. It is important that, regardless of the conversion, both catalysts showed high selectivity (S = 90–95%) for the double bond hydrogenation
