I The aqueous in freshly killed cynomolgus monkeys ivas replaced hy a solution of I-albumin and "I-diodone (iodopyracet). An inflow of this solution into the anterior chamber was produced by a horizontal buret placed above the eye, and at the same time the eye was continuously loashed through with the radioactive solution at a high rate by a push-pull arrangement. Fluid was collected from the d...

abstract one of the ways to increase economic and environmental efficiency of drainage systems is water table management. water table management consists of, controlled drainage and subirrigation. this study examines the effect of controlled drainage on yield, root distribution pattern and water use efficiency of maize (sc 704) in karaj. the experiment was performed as a randomized complete des...

PURPOSE To investigate why some patients with an intracranial dural arteriovenous fistula (DAVF) with spinal venous drainage have myelopathy and others do not. METHODS We reviewed the clinical and radiologic data for 12 patients who had a DAVF with spinal venous drainage diagnosed at our institutions from 1982 to 1995. RESULTS Six patients had progressive spinal cord indications of disease ...

PURPOSE Our purpose is to evaluate the efficiency and mean term complications in percutaneous bile drainage through a retrospective study of 50 cases METHODS Fifty patients aged from 24 to 87 years underwent perecutaneous bile drainage in the Radiology Department of Mongi Slim hospital. Patients had external drainage, internal drainage or endoprotheses. Clinical and biological features were u...

PURPOSE To evaluate the effect of internal-external percutaneous transhepatic biliary drainage (IEPTBD) for patients with malignant obstructive jaundice. METHODS During the period of January 2008 and July 2013, internal-external drainage was performed in 42 patients with malignant obstructive jaundice. During the procedure, if the guide wire could pass through the occlusion and into the duode...

The sustainability of irrigated agriculture in India is threatened by waterlogging, soil salinity, and alkalinity. To reverse declining agricultural productivity, a combination of surface and subsurface drainage, supplemented by improved irrigation management, has been identi®ed as the most appropriate strategy. But subsurface drainage for salinity control is costly. Therefore, its bene®ts in t...

BACKGROUND AND OBJECTIVES Despite previous studies demonstrating no difference in mortality or morbidity, the various surgical approaches for necrotizing enterocolitis (NEC) in infants have not been evaluated economically. Our goal was to compare total in-hospital cost and mortality by using propensity score-matched infants treated with peritoneal drainage alone, peritoneal drainage followed by...

Acid mine drainage (AMD) is one of the most significant environmental challenges facing the mining industry worldwide. Water infiltrating through the metal sulphide minerals, effluents of mineral processing plants and seepage from tailing dams becomes acidic and this acidic nature of the solution allows the metals to be transported in their most soluble form. The conventional treatment technolo...

A thin coal seam mined as a protective coal seam above a gas outburst coal seam plays a central role in decreasing the degree of stress placed on a protected seam, thus increasing gas permeability levels and desorption capacities to dramatically eliminate gas outburst risk for the protected seam. However, when multiple layers of coal seams are present, stress-relieved gas from adjacent coal sea...

OBJECTIVES To investigate the different effects of closed suction drainage and non-drainage for total knee arthroplasty(TKA) and to provide reference information for the choice of clinical treatment. METHODS Randomized controlled trials (RCTs) of closed suction drainage versus non-drainage for TKA were collected from the Cochrane Library, PubMed, EMBase, Springer, CBM, CNKI, VIP and WANFANG d...
