A METHOD FOR THE ESTIMATION OF TSUNAMI RISK ALONG RUSSIA’s FAR EAST

A simplified method was developed for estimating the tsunami risk for a coast for possible events having recurrence periods of 50 and 100 years. The method is based on readily available seismic data and the calculation of magnitudes of events with specified return periods. A classical Gumbel statistical method was used to estimate magnitudes of small probability events. The tsunami numerical modeling study used the average earthquake coordinates in the Kuril-Kamchatka high- seismic area. The verification and testing of the method were carried out using events from the North, Middle and South Kuril Islands – the most tsunami-risk areas of Russia’s Far East. Also, the study used the regional Kuril-Kamchatka catalogue of earthquakes from 1900 to 2008 - which included earthquakes with magnitudes of at least M=6. The results of the study indicate that the proposed methodology provides reasonable estimates of tsunami risk

An Analysis of the Chemical Composition of the Atmosphere of Venus on an AMS of the Venera-12 Using a Gas Chromatograph

Eight analyses of the atmosphere of Venus were made beginning at an altitude of 42 km right down to the surface of the planet. The following were detected in the atmosphere of Venus: nitrogen in concentrations of 2.5 plus or minus 0.5 volumetric %, argon ir concentrations (4 plus or minus 2) x 10 to the minus 3 power volumetric %, CO--(2.8 plus or minus 1.4) x 10 to the minus 3 power volumetric % and SO2 in concentrations (1.3 plus or minus 0.6) x 10 to the minus 2 power volumetric %. The upper limits were estimated for the content of oxygen and water equal to 2 x 10 to the minus 3 power and 10 to the minus 2 power volumetric %, respectively

Flow-injection systems for determining iron(III) and iodide with the use of catalytic reactions

Flow-injection systems with spectrophotometric detection were developed on the basic of catalytic reactions, namely, the Fe(III)-catalyzed oxidation of methanol with hydrogen peroxide and the iodide-catalyzed cerium-arsenite reaction. The developed systems were used to analyze industrial and natural waters. The detection limits attained were as low as 0.02 μg/mL of Fe(III) and 0.2 μg/mL of I- at relative standard deviations of 2-7% with the throughoutput of 35 and 25 h-1, respectively. © 1997 MAEe cyrillic signK Hayκa/Interperiodica Publishing

ВЛИЯНИЕ ИСКУССТВЕННОЙ ВЕНТИЛЯЦИИ ЛЕГКИХ НА РЕАЛЬНУЮ ЭНЕРГОПОТРЕБНОСТЬ У ПАЦИЕНТОВ ХИРУРГИЧЕСКОГО ОТДЕЛЕНИЯ РЕАНИМАЦИИ И ИНТЕНСИВНОЙ ТЕРАПИИ

Elective or emergence surgery often is closely connected with development of hypercatabolism-hypermetabolism syndrome. Non-effective and late nutritional support in surgical critically ill patients lead to several consequences and complications such as: wound and nosocomial infectons, gastric stress ulcers, pressure ulcers, prolonged artificial lung ventilation, increased length of stay in ICU and hospital. Energy deficit is one of the important components of critical illness and it corresponds with multiple organ dysfunction progression. Prospective study was provided in 18 beds surgical intensive care unit (SICU). 106 patient medical cards were divided into 4 groupstwo control and two basic with espiratory support (subgroup with artificial lung ventilation and subgroup without artificial lung ventilation). We compared the effectiviness of two methods for the estimation of patients energy needsspecial equations and indirect calorimetry. As a result we found out that main markers of energy and protein metabolism and nutritive status were significantly higher in indirect calorimetry groupswith and without artificial lung ventilation. Conclusion: Indirect calorimetry method usage for the estimation of energy needs in surgical ICU patients is more effective than special equations method during first 7 days of critical illness and may be recommended for clinical practice implication. Неотложное и плановое оперативное вмешательства всегда сопровождаются развитием синдрома гиперметаболизма гиперкатаболизма. Неадекватная и несвоевременная нутритивная поддержка при критических состояниях в клинике хирургических болезней приводит к развитию целого ряда неблагоприятных последствий и осложнений, таких как: раневые инфекции, нозокомиальные инфекции различной локализации, стрессовые язвы ЖКТ, пролежни, длительная искусственная вентиляция легких, длительное пребывание больного в отделении реанимации и интенсивной терапии (ОРИТ) и стационаре. Неотъемлемым компонентом критических состояний является энергодефицит, который поддерживает и приводит к прогрессированию синдрома полиорганной недостаточности. Проспективное когортное исследование проведено на базе 18-коечного хирургического отделения реанимации и интенсивной терапии. 106 историй болезней пациентов разделили на 4 группы две контрольные и две основные с респираторной поддержкой (подгруппа с искусственной вентиляцией легких (ИВЛ) и без респираторной поддержки (подгруппа без ИВЛ). Проведено сравнение метода расчетных уравнений и метода непрямой калориметрии для подбора оптимального количества вводимых больному калорий. В результате проведенного исследования показатели белково-энергетического и нутритивного статуса были достоверно лучше в группе непрямой калориметрии как у больных на ИВЛ, так и без ИВЛ. У пациентов в критическом состоянии, находившихся в хирургическом отделении реанимации и интенсивной терапии для проведения оценки их потребности в энергии целесообразно проводить непрямую калориметрию в первые 7 суто

Mass Transfer Mechanism in Real Crystals by Pulsed Laser Irradiation

The dynamic processes in the surface layers of metals subjected activity of a pulsing laser irradiation, which destroyed not the crystalline structure in details surveyed. The procedure of calculation of a dislocation density generated in bulk of metal during the relaxation processes and at repeated pulse laser action is presented. The results of evaluations coincide with high accuracy with transmission electron microscopy dates. The dislocation-interstitial mechanism of laser-stimulated mass-transfer in real crystals is presented on the basis of the ideas of the interaction of structure defects in dynamically deforming medium. The good compliance of theoretical and experimental results approves a defining role of the presented mechanism of mass transfer at pulse laser action on metals. The possible implementation this dislocation-interstitial mechanism of mass transfer in metals to other cases of pulsing influences is justifiedComment: 10 pages, 2 figures, Late

The XMM-Newton serendipitous survey. VII. The third XMM-Newton serendipitous source catalogue

Thanks to the large collecting area (3 x ~1500 cm$^2$ at 1.5 keV) and wide field of view (30' across in full field mode) of the X-ray cameras on board the European Space Agency X-ray observatory XMM-Newton, each individual pointing can result in the detection of hundreds of X-ray sources, most of which are newly discovered. Recently, many improvements in the XMM-Newton data reduction algorithms have been made. These include enhanced source characterisation and reduced spurious source detections, refined astrometric precision, greater net sensitivity and the extraction of spectra and time series for fainter sources, with better signal-to-noise. Further, almost 50\% more observations are in the public domain compared to 2XMMi-DR3, allowing the XMM-Newton Survey Science Centre (XMM-SSC) to produce a much larger and better quality X-ray source catalogue. The XMM-SSC has developed a pipeline to reduce the XMM-Newton data automatically and using improved calibration a new catalogue version has been produced from XMM-Newton data made public by 2013 Dec. 31 (13 years of data). Manual screening ensures the highest data quality. This catalogue is known as 3XMM. In the latest release, 3XMM-DR5, there are 565962 X-ray detections comprising 396910 unique X-ray sources. For the 133000 brightest sources, spectra and lightcurves are provided. For all detections, the positions on the sky, a measure of the quality of the detection, and an evaluation of the X-ray variability is provided, along with the fluxes and count rates in 7 X-ray energy bands, the total 0.2-12 keV band counts, and four hardness ratios. To identify the detections, a cross correlation with 228 catalogues is also provided for each X-ray detection. 3XMM-DR5 is the largest X-ray source catalogue ever produced. Thanks to the large array of data products, it is an excellent resource in which to find new and extreme objects.Comment: 23 pages, version accepted for publication in A&

Risk of Venous Thromboembolic Complications in Patients with Atrial Fibrillation: a Systematic Review and Meta-analysis

Aim: The aim of this meta-analysis and systematic review was to evaluate the possible connection between AF and VTE.Material and methods. Atrial fibrillation (AF) and atrial flutter (AFL) contribute to intra-atrial blood stasis which leads to thrombus formation with its embolization. There is some evidence that AF can be a risk factor for deep vein thrombosis (DVT) and pulmonary embolism (PE). The following databases were searched: PubMed (MEDLINE), EMBASE, Google Scholar, the Cochrane Central Register of Controlled Trials. The time frame for conducting a systematic literature search ranged from January 1, 1990 to November 1, 2021. The diagnosis of atrial fibrillation had to be confirmed by using ECG. The diagnosis of VTE could be made with Doppler imaging, ventilation/perfusion scan, CT angiography, venography, angiography or autopsy. Only the three studies with 102192 patients meeting the requirement were included in the meta-analysis.Results. The prevalence of DVT and PE were assessed using incidence rate ratios (IRR) method of the inverse variance random effects model and its 95% confidence interval (CI). The significant association between atrial fibrillation and pulmonary embolism was found (IRR, 4.18 95% Cl 1.958.98). Also there is obvious association between DVT and AF (IRR, 2.97 95% Cl 2.18-4.03).Conclusion. It can be concluded that the increased risk of developing VTE is associatedwith concomitant AF
