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...

Biofilms are organized structures composed mainly of cells and extracellular polymeric substances produced by the constituent microorganisms. Ubiquitous in nature, biofilms have an innate ability to capture and retain passing material and may therefore act as natural collectors of contaminants or signatures of upstream activities. To determine the persistence and detectability of DNA passing th...

in tunisia, kalâat el andalous irrigated district is one of the most affected areas by salinization. the objective of this study was to predict the root zone salinity (over 10 years) in this area using the saltmod simulation model for subsurface drainage system. saltmod is based on water balance, salt balance model, and seasonal agronomic aspects. in the pilot area, irrigated vegetables crops s...

Figure 2 Clinical photograph demonstrating the long distal drain still protruding after closure of the arthrotomy (Fig 1). Close the arthrotomy from proximal to distal, leaving the distal end protruding (Fig 2). As you reach the end of the wound where the drain exits the arthrotomy, withdraw the drain to length. As the drain withdraws easily, you can be sure that it has not been sutured into th...

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...

Based on the biaxial experiment data of membrane material under hot and cold conditions, mechanical properties calculation model envelope was established with consideration effects varying stress ratios, magnitudes temperatures near-space airship material. Using heat source model, Computational Fluid Dynamics (CFD) simulation, User-Defined Function (UDF), structural finite element analysis soft...

Conduction characteristics of amorphous InGaZnO thin-film transistors were investigated by applying constant drain current with gate bias (V GS) modulation. Constant drain current in the off-current (I off) level from the transfer characteristic was applied to the drain electrode and the measured drain voltage with the gate bias sweep. The normalized channel conductance (G d) characteristics we...
