The article presents data on measurements of methane fluxes at largest Russian reservoirs, carried out in August and September 2021 under long-term research project.
In this article data concerning coherent fluctuation nephelometry (CFN) use in clinical microbiology is presented. CFN-analyzer allows to solve two important problems – fast urine screening for ...bacteriuria within 2-4 hours and antibiotic susceptibility testing within 3-6 hours. Altogether more than 650 urine samples were tested, and the effectivity of CFN-analyzer for preliminary selection of samples for further analysis was shown. Method allows to detect negative samples, reducing the number of urine analyses by 70-80%. Simultaneous analysis of growth curves and concentration of microorganisms shows high sensitivity and specificity (95.2% и 96.9%). Also more than 250 antibiotic susceptibility tests were performed using CFN-analyzer to show its effectiveness for determination of resistant properties of both pure cultures and urine microflora without isolation of bacteria. The agreement with traditional methods was from 84% to 88%. The use of CFN-analyzer with express methods of identification of microorganisms (chromogenic nutrient broths or mass-spectrometry) allows to make full urine analysis within 1-2 days. In the future CFN-analyzer gives an opportunity to screen different human biological liquids, and finds an application for other microbiological tasks, including standardization and speeding-up in sanitary bacteriology.
The article deals with the techniques of soil water content determination using microwave radiation. Its practical application would allow solving the problems of resource efficiency in geotechnical ...survey due to reduction of energy and resource intensity of laboratory analysis as well as its acceleration by means of decreasing labour intensity and, as a result, cost reduction. The article presents a detail analysis of approaches to soil water content determination and soil drying, considers its features and application. The study in soil of different composition, typical for Western Siberia including organic and organic-mineral ones, is a peculiarity of the given article, which makes it rather topical. The article compares and analyzes the results of the investigation into soil water content, which are obtained via conventional techniques and the original one developed by the authors, consisting in microwave drying. The authors also give recommendation on microwave technique application to dry soil.
To improve the results of surgical treatment of benign prostatic hyperplasia.
The study investigated the effectiveness of a comprehensive preoperative preparation of patients with benign prostatic ...hyperplasia. The clinical efficacy of traditional methods of preoperative preparation (compression bandaging of the lower extremities during surgery and in the postoperative period and Fraxiparine at a prophylactic dose) was compared with the same preoperative protocol used in combination with intravenous laser blood irradiation. The explored parameters included changes in clinical and laboratory coagulation indices and prostatic blood flow measured by Doppler sonography. The real time visualization was used to assess the effect of intravenous laser irradiation of blood on the morphofunctional state of platelets.
The study findings showed a high effectiveness of intravenous laser blood irradiation in preoperative preparation of patients with benign prostatic hyperplasia. It was found to reduce the incidence of thrombotic events by 6% and hemorrhagic complications by 4.9% (p<0.05).
