Background & Importance: Chronic subdural hematoma (CSH) is one of the most frequent intracranial hemorrhages in adults. However, gold standard treatment of CSH is not yet defined. Since the 80’s, closed drainage is a standard among techniques using drains because the open type has been incriminated in high rates of postoperative infections. However, closed drainage requires mat...

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...

This article deals with the quenching of kinetic energy flow to lower reaches low and medium pressure reservoirs determination strength structure, rational size structural elements power extinguishers, intermediate distances. The study aimed ensure that distance hydraulic jump movement water is shortened, increase reliability construction operation drainage facilities by determining Froude numb...

the aim of this paper is to introduce new methods of colorectal and anus surgeries. it is not a comprehensive paper and just is a summary of issues related to colon surgeries due to intestinal inflammatory diseases (ulcerative colitis and crohn's disease), and anus cancer. ulcerative colitis usually initiates from rectum and then develops upward to colon. there are three methods of surgery...

chronic subdural hematoma (csdh) is a curable entity frequently encountered by neurosurgeons. the present study was conducted to explore expert opinion and common practice in iran. besides, a review of randomized clinical trials in literature was performed. a questionnaire including six questions discussing major aspects of practice on csdh, with multiple choices was designed. a pilot study was...

Transients in water content are well-known to mobilize microorganisms that are retained in the vadose zone. However, there is no consensus on the relative importance of drainage and imbibition events on microorganism release. To overcome this limitation, we have systematically studied the release of Escherichia coli D21g during cycles of drainage and imbibition under various solution chemistry ...

controlled drainage is one of the strategies to reduce negative environmental effects in conventional drainage systems. this study examines the effect of controlled drainage on quality and quantity of drainage water, specifically amounts of salt and nitrate in drainage water, and nitrate uptake by maize (sc 704) with sandy loam soil texture in karaj. the experiment was performed as a randomized...

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...
