OBJECTIVES This is a prospective case-control study that was conducted to determine if the addition of intraoperative powdered vancomycin placed directly into the wounds at the time of closure might decrease the rate of acute postoperative infection after the placement of spinal cord stimulator paddle leads. MATERIALS AND METHODS A retrospective analysis of the author's practice from January ...

Background The novel bioreactor system from PBS Biotech is the first with a pneumatic mixing device powered solely by gas buoyancy, eliminating the need for an external mechanical agitator. The patented design of the AirWheel mixing device promotes not only high tangential fluid flow around the wheel but also efficient radial and axial flows. The leverage effect of the Air-Wheel mixing device a...

OBJECTIVES/HYPOTHESIS The purpose of this study was to analyze our experience with the composed double skin paddle fibula free flap to reconstruct large mandibulofacial defects. STUDY DESIGN Between 2006 and 2011, a total of 32 composed double skin paddle fibula free flap procedures were performed on 32 patients (mean age 54.4 ± 9.7 years, mean follow-up period of 3.4 ± 1.7 years). METHODS ...

Optimizing the desired properties for stretch monolayer separators used in Lithium-ion batteries has been a challenge. In the present study a cellulose nanofiber/PET nonwoven composite separator is successfully fabricated, using a wet-laid nonwoven (papermaking) process, which can attain optimal properties in wettability, mechanical strength, thermal resistance, and electrochemical performance ...

In this research, inorganic material type and content influence on coating of commercially available polypropylene (PP) separator were studied for improving its performance and safety as lithium ion battery separator. Heat-resistant nanopowders of Al2O3, SiO2 and ZrO2 were coated using polyvinylidene fluoride (PVDF) binder. Coating effects on the separators morphology, wettability, high tempera...

Currently, computational fluid dynamics has become the primary method for analyzing flow state inside machine. Herein, Ansys Fluent software is used to design a more effective oil-field device, namely, gas–liquid cylindrical cyclone (GLCC)-horizontal combined separator. The characteristics of mixed flow, turbulence intensity, and phase volume fraction distribution are analyzed, factors affectin...
