In this letter, the characteristics of positive bias temperature instability (PBTI) and hot carrier stress (HCS) for the lowtemperature poly-Si thin-film transistors (LTPS-TFTs) with HfO2 gate dielectric are well investigated for the first time. Under room temperature stress condition, the PBTI shows a more serious degradation than does HCS, indicating that the gate bias stress would dominate t...

This study was designed to calibrate and evaluate the subsurface drain flow component of the Root Zone Water Quality Model (RZWQM; Version 2.5) for four tillage-systems: chisel plow (CP), moldboard plow (MB), no-tillage (NT), and ridge-tillage (RT). Measured subsurface drain flow data for 1990 was used for model calibration. Main parameters calibrated were lateral saturated hydraulic conductivi...

INTRODUCTION Though surgical drainage is used as a safety measure, it's not without complications. Migration of various drains has been described, but very little literature refers to the migration of peritoneal drain. PRESENTATION OF CASE A 55-year male underwent anterior Gastro-Jejunostomy for inoperable metastatic carcinoma of the Gastric Pylorus. We found the peritoneal drain missing on t...

Introduction: Regarding cholecystectomy for acute cholecystitis, there is still debate regarding drain insertion. The aim of the present study was to detect if there is a beneficial added value to drain the abdomen in case of laparoscopic cholecystectomy for acute cholecystitis. Patients and Methods: A total of 120 patients diagnosed having acute cholecystitis were enrolled to this study and we...

A 73-year-old patient underwent pyloruspreserving pancreatic head resection due to a branch-duct type intraductal papillary mucinous neoplasm. At Day 7, repeat laparotomy was performed because of elevated amylase concentrations in the abdominal drains. During the procedure, signs of pancreatitis were observed but no pancreaticogastrostomy leak was seen. Drains provided continuous irrigation. At...

background developing controlled hypercarbia is a known scheme of lowering the suprasellar part of the adenoma in order to assist the surgeon, which acts through raising the icp and therefore the csf pressure. objectives the purpose of this study is to compare the effect of introducing a lumbar drain with that of controlled hypercapnia on the quality of transsphenoidal pituitary tumor resection...

antepartum mastitis is a rare condition, whereas postpartum or lactation mastitis is a common problem. this report introduces a case of complicated bilateral antepartum mastitis, which was treated successfully by drain insertion and antibiotic therapy. the patient was a 23-year-old woman in the 23 rd week of her first pregnancy. her chief complaint was progressive swelling, redness and radicula...

there are human and animal health concerns related to drainage systems because nutrients, especially nitrogen and phosphorus, can contaminate water supplies. a field study was conducted on consolidated paddy fields of sari agricultural sciences and natural resources university, northern iran (36.3°n, 53.04°e), to determine the effect of subsurface drain depth and spacing on nitrogen (n) and pho...

background: modified radical mastectomy (mrm) is still one of globally accepted surgical techniques for breast cancer and in some selected patient is the gold standard type of surgery. the most frequent complication of this procedure is seroma under skin flaps or in the axilla as reported as much as 30% in some studies. the use of closed suction drainage system to reduce the incidence of this c...
