Drain vortices are among the most common observed in everyday life, yet their physics is complex due to competition of vorticity's transport and diffusion, presence viscous layers a free surface. Recently, it has become possible study experimentally drain superfluid liquid helium, fluid which simplified by absence viscosity quantisation circulation. Using Gross-Pitaevskii equation, we make simp...

The nitrates (NO(3)-N) lost through subsurface drainage in the Midwest often exceed concentrations that cause deleterious effects on the receiving streams and lead to hypoxic conditions in the northern Gulf of Mexico. The use of drainage and water quality models along with observed data analysis may provide new insight into the water and nutrient balance in drained agricultural lands and enable...

OBJECTIVES This paper sought to determine if there were an association between drain placement and the incidence of wound complications. MATERIALS AND METHODS A single-center institutional review board-approved retrospective study between 2001 to 2008, comparing 680 kidney transplant patients who either had a drain placed or were left undrained. Linear regression modeling was used to adjust t...

INTRODUCTION In many facilities, drains are routinely inserted after thyroidectomy with the aim of preventing hematoma formation and accumulation of seroma. The continued use of drains may be based more on tradition rather than proven scientific evidence. OBJECTIVE To assess the benefit of drain use after thyroidectomy by determining; length of hospital stay, post operative pain and wound sep...

Background: Thyroidectomy is one of the most difficult surgical procedures. The study aims to compare thyroidectomy procedure with drain placement and without concerning hospital stay, Postoperative complications, pain assessment using a visual analog scale. Methods: A prospective comparative was designed in Department otorhinolaryngology & Head Neck Surgery---removed for blind review----. ...

Water is the main source for domestic, engineering, industrial, agricultural and multipurpose uses which affects its supply and demand due to rapid rise in population. Occurrence and movement of groundwater are controlled by the degree of weathering, fracturing, the geomorphological set up and precipitation [1,2] Scarcity of potable drinking water is one of the major development issues in parts...
