Dynamics of methane content alterations in the Earth's atmosphere in the conditions of globalization is analyzed and methane emission sources are estimated. Oil and gas industry is proved to be the most important anthropogenic source of atmospheric methane growth. Natural mechanisms of methane concentration regulation in the biosphere are considere...

The analysis is made of natural and anthropogenic sources of methane emission into the atmosphere-one of the important greenhouse gases. New quantitative estimates of methane intake from wetland ecosystems, municipal solid waste landfills, agricultural production, and rapidly developing oil and gas industry are given. The dynamics of oil and gas in...

Knee joint replacement (KJR) is often complicated by deep venous thrombosis in the veins of the lower extremities. The rate of thrombotic complications of KJR is quite variable in various clinics, and is within 9-64 % according to the data of the studies. Deep veins of the leg are difficult to examine. The sensitivity of duplex scanning (DS) for id...

The purpose of this study is to conduct environmental assessment with the help of different biological benchmarks on the territory of a town where there is no significant industry load. The aspects explored are the morphoses of tree vegetation, fluctuating asymmetry of leaves, changes in soil biological activity in an urban setting, and particular...

METHANE IN THE ATMOSPHERE: DYNAMICS AND SOURCES This article is dedicated to the problem of the atmospheric concentration increase of one of the most dangerous greenhouse gases-methane, the main component of natural gas. The main natural and anthropogenic sources of methane emission are described in the article. The dynamics of oil and gas industry...

Objective – to identify the clinical and laboratory values relating to development of unstable thrombosis in patients with polytrauma. Materials and methods. The analysis included 56 patients with polytrauma. 26 (46.4 %) patients demonstrated acute venous thrombosis (AVT), including 10 (38.5 %) cases with floating thrombosis in the superficial femo...

Transfusion of donor red blood cells with structural and functional degradation worsens the state of microcirculation and creates some conditions for development of DIC and thrombotic complications. Objective - to investigate the influence of the methods for replacement of blood loss on the values of central hemodynamics, metabolism, severity of st...

Currently, venous thrombosis and pulmonary embolism are the common complications after injuries. However, most trauma centers do not have necessary standardization for their prevention and treatment. Materials and methods. The domestic and foreign literature was investigated for identification of the common protocols and algorythms for diagnostics...

Regularities of application of glow discharge spectrometry are considered for quantitative layer-by-layer analysis of thin coatings on steels. The known methods of surface analysis used in industry and in research are compared. The main fields of application of glow discharge spectrometry are considered. The key causes for distortion of the analyti...

Retrospective analysis of case histories of 125 patients (36-77 years) after total knee arthroplasty for III-IV stage of gonarthrosis was performed. On 4-5 day after operation deep vein thrombosis was diagnosed in 30 (23.6%) patients. It was stated that additional factors which trustworthily influenced the risk factors of thromboembolic complicatio...

Hip joint endoprosthetic replacement (HJER) leads to hemodynamic disorders and massive intraoperative hemorrhage and presents a high risk (30?55% of cases) for postoperative deep vein thrombosis in the lower extremity, at the same time the possibility (12?22%) of massive pulmonary thromboembolism (PTE) is ruled out. So the choice of infusion-transf...

The actuality of the problem is conditioned by the high death rate and invalidism of working-age persons, which is a severe burden for society. Our aim was the analysis of the cerebral hemodynamics in young patients during an acute period of ischemic stroke (IS). We examined 17 patients (nine men and eight women) with IS, their mean age was 44.2...

Epichlorohydrin is generally obtained from allyl chloride by a method which involves chlorination of propylene to allyl chloride, hypochlorination of allyl chloride to glycerin dichlorohydrins, and dehydrochlorination of the latter to form epichlorohydrin. Shortcomings of this method have led to a search for other methods of synthesis which attempt...
