subsurface drainage systems are used to control the depth of the water table and to reduce or prevent soil salinity. water flow in these systems is described by the boussinesq equation, and the advection-dispersion equation coupled with the boussinesq equation is used to study the solute transport. the objective of this study was to propose a finite difference solution of the advection-dispersi...

OBJECTIVES The purpose of this retrospective study was to compare the amount of postoperative drainage via closed suction drainage system after intraoral vertical ramus osteotomy (IVRO) and sagittal split ramus osteotomy (SSRO). MATERIALS AND METHODS We planned a retrospective cohort study of 40 patients selected from a larger group who underwent orthognathic surgery from 2007 to 2013. Mean a...

OBJECTIVES Gait abnormalities are an early clinical symptom in normal pressure hydrocephalus (NPH), and subjective improvement in gait after temporary removal of CSF is often used to decide to perform shunt surgery. We investigated objective measures to compare gait before and after CSF drainage and shunt surgery. DESIGN Twenty patients and nine controls were studied. Quantitative gait measur...

The aim of this paper is to present the descriptive and empirical results of the survey responses regarding the gear oil drainage from end-of-life vehicle (ELV). The study evaluates the various drainage procedures and its effects on drainage time, amount of gear oil drained out and the cars processed daily. The survey results suggest that there are differences in manual, semi-automatic and full...

PURPOSE OF REVIEW The purpose of this review is to critically compare the various glaucoma drainage implants in popular use. RECENT FINDINGS Glaucoma drainage implants are being increasingly utilized in the surgical management of glaucoma. Comparisons between the various drainage implants are difficult because most clinical data are derived from retrospective studies with different study popu...

The main purpose of the research is to find the solution of drainage issues in high-rise building through the observation and basic study of stack fluid mechanism. Firstly, we will investigate the existing high-rise buildings and summarize the design methodology from our previous researches. Through the observations and reviews, this paper would conclude the solutions for existing drainage prob...

BACKGROUND Surgery in patients with obstructive jaundice caused by a periampullary (pancreas, papilla, distal bile duct) tumor is associated with a higher risk of postoperative complications than in non-jaundiced patients. Preoperative biliary drainage was introduced in an attempt to improve the general condition and thus reduce postoperative morbidity and mortality. Early studies showed a redu...
