Isolation of Soil Thiobacterii and Determination of Their Bio-Oxidation Activity

36 strains of sulfur-oxidizing bacteria were isolated in Southern Kazakhstan soda-saline soils and identified. Screening of strains according bio-oxidation (destruction thiosulfate to sulfate) and enzymatic (Thiosulfate dehydrogenises and thiosulfate reductase) activity was conducted. There were selected modes of aeration and culture conditions (pH, temperature), which provide optimum harvest cells. These strains can be used in bio-melioration technology

Raman Study of Polycrystalline Si3N4 Irradiated with Swift Heavy Ions

A depth-resolved Raman spectroscopy technique was used to study the residual stress profiles in polycrystalline silicon nitride that was irradiated with Xe (167 MeV, 1 × 1011 cm−2 ÷ 4.87 × 1013 cm−2 ) and Bi (710 MeV, 1 × 1011 cm−2 ÷ 1 × 1013 cm−2 ) ions. It was shown that both the compressive and tensile stress fields were formed in the irradiated specimen, separated by a buffer zone that was located at a depth that coincided with the thickness of layer, amorphized due to multiple overlapping track regions. The compressive stresses were registered in a subsurface region, while at a greater depth, the tensile stresses were recorded and their levels reached the maximum value at the end of ion range. The size of the amorphous layer was evaluated from the dose dependence of the full width at half maximum (FWHM) (FWHM of the dominant 204 cm−1 line in the Raman spectra and scanning electron microscopy. © 2021 by the authors.

Importance of the Caspian Countries for the European Union

When there is a lack of energy resources in the EU and it has to look for suppliers from other countries, Russia provides the world with most of the oil and gas. Diversification of energy resources is one of the objectives for the EU. The majority of international participants are interested in discovering the potential of the sea. However, the development of the region’s resources still faces many obstacles, such as lack of export pipelines, difficulties due to security of supply considerations, transit complications, political and legal considerations and market uncertainties. This study focuses on the countries of the former Soviet Union such as Uzbekistan, Kazakhstan and Turkmenistan in Central Asia, and Azerbaijan in Transcaucasia. One of the six priority areas of the EU in the energy infrastructure of - the Southern Energy Corridor (SEC), the purpose of which is to link the Caspian basin and potentially Middle Eastern gas to Europe. In the article, we analyzed the potential of the Caspian basin in terms of energy and its impact on the energy security of the European Union.Коли в ЄС виникає брак енергоресурсів, і він повинен шукати постачальників з інших країн, Росія забезпечує світ більшістю нафти та газу.

Lasia spinosa Chemical Composition and Therapeutic Potential: A Literature-Based Review

Lasia spinosa (L.) is used ethnobotanically for the treatment of various diseases, including rheumatoid arthritis, inflammation of the lungs, bleeding cough, hemorrhoids, intestinal diseases, stomach pain, and uterine cancer. This review is aimed at summarizing phytochemistry and pharmacological data with their molecular mechanisms of action. A search was performed in databases such as PubMed, Science Direct, and Google Scholar using the keywords: "Lasia spinosa,"then combined with "ethnopharmacological use,""phytochemistry,"and "pharmacological activity."This updated review included studies with in vitro, ex vivo, and in vivo experiments with compounds of known concentration and highlighted pharmacological mechanisms. The research results showed that L. spinosa contains many important nutritional and phytochemical components such as alkanes, aldehydes, alkaloids, carotenoids, flavonoids, fatty acids, ketones, lignans, phenolics, terpenoids, steroids, and volatile oil with excellent bioactivity. The importance of this review lies in the fact that scientific pharmacological evidence supports the fact that the plant has antioxidant, anti-inflammatory, antimicrobial, cytotoxic, antidiarrheal, antihelminthic, antidiabetic, antihyperlipidemic, and antinociceptive effects, while protecting the gastrointestinal system and reproductive. Regarding future toxicological and safety data, more research is needed, including studies on human subjects. In light of these data, L. spinosa can be considered a medicinal plant with effective bioactives for the adjuvant treatment of various diseases in humans.This work was supported by Comisión Nacional de Investigación Científica y Tecnológica (CONICYT) PIA/APOYO CCTE AFB170007.

Latent tracks of swift Bi ions in Si3N4

Parameters such as track diameter and microstruture of latent tracks in polycrystalline Si3N4 induced by 710 MeV Bi ions were studied using TEM and XRD techniques, and MD simulation. Experimental results are considered in terms of the framework of a 'core-shell' inelastic thermal spike (i-TS) model. The average track radius determined by means of electron microscopy coincides with that deduced from computer modelling and is similar to the track core size predicted by the i-TS model using a boiling criterion. Indirect (XRD) techniques give a larger average latent track radius which is consistent with the integral nature of the signal collected from the probed volume of irradiated material. © 2020 The Author(s).
