} 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...
PURPOSE To study the microsurgical anatomy of the lacrimal drainage system and to provide anatomical evidence for transnasal endoscopic lacrimal drainage system bypass surgery by autogenous tissue grafting. MATERIALS AND METHODS A total of 20 Chinese adult cadaveric heads in 10% formaldehyde, comprising 40 lacrimal ducts were used. The middle third section of the specimens were examined for t...
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 pati...
This paper proposes a decision treemodel for specifying the importance of 21 factors causing the landslides in a wide area of Penang Island, Malaysia. These factors are vegetation cover, distance from the fault line, slope angle, cross curvature, slope aspect, distance from road, geology, diagonal length, longitude curvature, rugosity, plan curvature, elevation, rain perception, soil texture, s...

introductapplication of neural network of multi layers perceptron (mlp) in site selection of municipal solid waste landfilling with emphasis on hydrogeomorphic characteristics (case study: fereydoonshahr city)introduction:cities are at the nexus of a further threat to the environment, namely the production of an increasing quantity and complexity of wastes. the estimated quantity of munici...
Outburst closed distance coal seam distances are extremely difficult to mine, and commonly involved in safety accidents the process of mining. Based on engineering background Wulan Coal Mine at western margin Ordos Basin, this paper presents a theoretical analysis, analogies, numerical simulations determine optimal mining sequence for #7, #8, #2, #3 seams. Floor penetration drilling was used el...
The gas in a coal seam is clean energy source, but it also the main cause of accidents during mining mineral resources. There large pressure–relief influx upper and lower adjacent layers 1211 working face Wanfeng Coal Mine Jinhui, Shanxi Province, China. Based on evolution law overburden fractures, collaborative extraction mode “directional drilling gas-conducting fractured zone + staggered bur...
