External drainage of subretinal fluid during scleral buckling procedures is considered by many ophthalmologists to be a rather dangerous and uncontrolled process owing to the potential for complications such as retinal incarceration, subretinal hemorrhage, and loss of vitreous. Typically, drainage is monitored externally, with only intermittent use of indirect ophthalmoscopy to assess drainage ...

BACKGROUND Problems in the management of thoracic trauma have stimulated the search for an alternative to underwater seals for drainage of the pleural cavity. A chest drainage bag incorporating a one way flutter valve has been compared with underwater seal drains in a randomised clinical trial. METHODS During June-December 1989 119 patients undergoing elective thoracotomy were randomised to r...

Walled-off pancreatic necrosis (WOPN) is one of the most life-threatening complications of acute severe pancreatitis. Regarding its high mortality and morbidity without appropriate treatment, the drainage procedure is still the mainstay of the treatment for this condition. There are multiple drainage options for this event. To date, endoscopic drainage alone has not been adequate for this condi...

Considering characteristics of high river density, special underlying surface in plain river network region, and municipal drainage system function, river network drainage unit model is proposed, which is defined as a region surrounded by main river or embankment. Flood storage variety and control projects regulation of small rivers in each unit is simulated. With drainage catchment as an objec...

S29 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 Noble Gatro Hospital, Ahmedabad, Gujarat, India Endoscopic ultrasound (EUS)-guided pelvic abscess drainage though uncommon modality for definite treatment of pelvic abscess is an effective method of treatment for pelvic abscess due to its proximity to rectal wall. We performed drainage of pelvic abscess in a 65-year-old male with...

In GIS and in terrain analysis, drainage systems are important components. Due to local topography and subsurface geology, a drainage system achieves a particular drainage pattern based on the form and texture of its network of stream channels and tributaries. Drainage pattern recognition helps to provide a qualitative description of the terrain for analysis and classification and is useful for...

Lundin, L. 1994. Impacts of forest drainage on flow regime. Studia Forestalia Suecica 192. 22 pp. ISSN 0039-3150, ISBN 91-576-4872-7. High floods in watercourses are of great interest. because of the potential hazards they pose to people and low-lying land near rivers. In many parts of the world, inundations are common and in northwest Europe there are high discharges almost every year, occasio...

Biliary drainage is a radical method to relieve cholestasis, a cause of acute cholangitis, and takes a central part in the treatment of acute cholangitis. Emergent drainage is essential for severe cases, whereas patients with moderate and mild disease should also receive drainage as soon as possible if they do not respond to conservative treatment, and their condition has not improved. Biliary ...

in the present  paper electrical conductivity (ec) of colloidal gas aphron (cga) suspensions was measured for anionic and cationic surfactants (sodium dodecyl sulfate (sds) and tetradecyl trimethyl ammonium bromide (ttab)). experiments were made for different concentrations of sds (6, 8.1, 10 mm) and ttab (2, 3.51, 5 mm). cga drainage behavior was observed and measured using 1 liter measuring c...
