One important trend in recent years is the reduction of the silicon film thickness in SOI devices. As results of scaling this parameter several benefits have been obtained such as the elimination of the kink effect, the suppression of short-channel effects, improved subthreshold characteristics, the enhancement of carrier mobility, suppression of punchthrough and drain current overshoot and so ...

PURPOSE The aim of this study was to compare a negative pressure drain with a natural drain in order to determine whether a negative pressure drainage tube causes an increase in the drainage volume. MATERIALS AND METHODS Sixty-two patients who underwent total thyroidectomy for papillary thyroid carcinoma (PTC) were enrolled in the study between March 2010 and August 2010 at Gyeongsang Nationa...

OBJECTIVE To perform an unbiased assessment of first postoperative day (POD 1) drain amylase level and pancreatic fistula (PF) after pancreaticoduodenectomy (PD). BACKGROUND Recent evidence demonstrated that drain abandonment in PD is unsafe. Early drain amylase levels have been proposed as predictors of PF after PD, allowing for selection of patients for early drain removal. METHODS Daily ...

Most research on the phenomenon of "brain drain" (one-way flow of highly skilled/educated individuals) has focused on movement between the least developed and most highly developed countries. Therefore, the significance of patterns of migration to middle-income countries such as those in Latin America is less clear. The aim of this study was to outline key features of international health worke...

Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence. This study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis. A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital, Abha, Saudi Arabia, was conducted from April 2010 t...

It cannot be ignored that Iran had an impressive history in science over the very ancient years; through significant number of unique inventions, ideas, and discoveries brought by Iranian scientists such as Farabi, Toosi, Razes, Avicenna, Hesabi, and many others. During centuries due to political, cultural circumstances and war, Iran's activities in all aspects of science and technology (S & T)...

this study is an attempt to develop an integrated methodology to predict the impact of the caspian sea on flooding using geographic information systems (gis) and hydrodynamic modeling. a rise in the sea level might lead to major flooding events, and have a severe impact on the spatial development of cities and regions. the feasibility of simulating a flood event along a drain channel is evaluat...

STUDY DESIGN Retrospective clinical study. PURPOSE To assess the diagnostic value of suction drain tip culture in patients undergoing primary posterior spine surgery. OVERVIEW OF LITERATURE To date, the diagnostic value of suction drain tip culture for predicting surgical site infection (SSI) has not been firmly established in orthopedic or spinal surgery. METHODS In total, 133 patients w...
