} Background: Proper drainage of the mediastinal and pleural spaces following Off-Pump Coronary Artery Bypass (OPCAB) surgery is essential for the prevention of pleural and pericardial effusions, cardiac tamponade and late complications such as constrictive pericarditis. Drainage tubes themselves may induce some complications which can negatively affect the result of the surgery. In th...
Abstract This study investigates the contamination potential of herbicides to groundwater with help numerical modeling (HYDRUS‐1D) and stable carbon isotopes for characterizing biodegradation. Four herbicides, metolachlor, terbuthylazine, prosulfuron, nicosulfuron, were applied over a period 4.5 years on two lysimeters located in Wielenbach, Germany, monitored by lysimeter drainage. These conta...
Saturated hydraulic conductivity (Ksat) is a key soil parameter for representing infiltration and drainage in land surface models. For large scale applications, Ksat often estimated from pedotransfer functions (PTFs) based on easy-to-measure properties like texture bulk density. The reliance of PTFs data uniform arable lands the omission structure limits applicability texture-based predictions ...
This report summarizes the results of 64 percutaneous catheter drainage of abdominal abscesses and fluid collections in 56 patients. Aspiration and drainage was guided with computed tomography in 34 patients and with ultrasound in 30 patients. Success rate was 90%. Infected collections were successfully drained in 94% and noninfected collections in 72% . Partial success was achieved in two...
watershed is regarded as a very complex system of natural, social, economic and ecological dimensions and like any similar systems, exploitation of its resources requires a comprehensive and coordinated planning and management. given the importance of watershed management projects for the development and management of natural resources, the enhancement of the efficiency of these activities is e...
Abstract This study aims to create a terrain classification of Japan that allows both geomorphological and geoengineering classifications coexist without large contradictions distinguish landform elements even in urban plains which include noise associated with digital elevation models (DEMs). Because is susceptible natural disasters, we designed the reflect ground vulnerability alluvial mounta...
Second, we believe that to compare the two surgical techniques, there must be a certain consistency in the two study groups. The authors only indicate the age and sex distribution of both groups, however it is very important to know several things that make the series are not significantly homogeneous and therefore the results may be biased. It is important to know that the degree of clinical s...
Abstract Flat lakes with a large catchment area are especially affected by sediment inputs. The Kolleru Lake (south-eastern India) surface of approximately 6121 km 2 belongs to such types lake basins. study’s main objective was the assessment both soil erosion and yield concentration rate catchment. study conducted using revised universal loss equation (RUSLE) model due its simple good applicab...
An automated process for the delineation of drainage basins, using as input only the vector based drainage network, is described which provides an alternative to DEM based methods. The procedure involves an approximation of the line Voronoi diagram for the network using a constrained Delaunay triangulation of the network's Planar Straight Line Graph. The constrained triangulation, which include...
We posed six clinical questions (CQ) on preoperative biliary drainage and organized all pertinent evidence regarding these questions. CQ 1. Is preoperative biliary drainage necessary for patients with jaundice? The indications for preoperative drainage for jaundiced patients are changing greatly. Many reports state that, excluding conditions such as cholangitis and liver dysfunction, biliary dr...
