BACKGROUND The ultrasonic scalpel is a recently introduced device in head and neck surgery. Total thyroidectomy is the most common endocrine procedure performed by surgeons. METHODS This was an open, phase IV, multicenter, randomized controlled trial (RCT) that compared the use of an ultrasonic scalpel with a conventional technique in patients who underwent total thyroidectomy. The outcomes w...
Recurrent chronic obstructive pancreatitis is attributed to pancreatic flow obstruction caused by PD stenosis, pancreatolithiasis, pancreas divisum, etc., and the consequent increased internal pressure in the caudal PD [1-3]. Methods of PD decompression include surgical procedures, such as pancreatectomy and pancreaticojejunostomy, as well as endoscopic PD stenting combined with extracorporeal ...
43 A is an important water management practice in the midwestern United States to remove excess water from poorly drained areas and to provide traffi cable conditions for agricultural production. About 30% of the total land area and 50% of the crop land in Indiana is subsurface drained (Economic Research Service, 1987). Th ere are growing concerns about the potential negative environmental impa...
Nowadays, acid mine drainage (AMD) is one of the most important problems in coal mine contamination. The Karmozd coal mines in Mazandaran Province are one of the largest and oldest coal extractions in Central Alborze Coal Basin. The samples of coals, host rocks, mine drainages and secondary surface minerals have been collected in summer season of 2005. On the basis of hydrogeochemistry studies ...
[1] Many landscapes are composed of ridges and valleys that are uniformly spaced, even where valley locations are not controlled by bedrock structure. Models of long-term landscape evolution have reproduced this phenomenon, yet the process by which uniformly spaced valleys develop is not well understood, and there is no quantitative framework for predicting valley spacing. Here we use a numeric...
abstract although lateral drains play the main role in removal of excess water from soil profile in subsurface drainage systems, but it is assumed that perforated collectors can directly remove a part of drainwater from soils. this part of discharge in subsurface drains is not usually taken into consideration in drainage design criteria, due to lack required information and its difficult estima...
This is a case of a 45-year-old woman, with known alcoholic liver disease who presented with a large right-sided pleural effusion. A pleural tap was performed followed by insertion of an intercostal drain. 7 litres were drained over 4 h and only 300 ml of 20% albumin were administered with the patient becoming acutely short of breath and requiring admission to the intensive treatment unit due t...
Abstract. By regulating the amount, timing, and location of meltwater supply to glacier bed, supraglacial hydrology potentially exerts a major control on evolution subglacial drainage system, which in turn modulates ice velocity. Yet configuration hydrological system has received only little attention numerical models so far. Here we apply two-dimensional model GlaDS (Glacier Drainage System mo...
INTRODUCTION Acute diverticulitis (AD) is increasingly seen in Emergency services. The application of a reliable classification is vital for its safe and effective management. OBJECTIVE To determine whether the combined use of the modified Neff radiological classification (mNeff) and clinical criteria (systemic inflammatory response syndrome [SIRS] and comorbidity) can ensure safe management ...
