We compared semiquantitative central venous catheter tip cultures plated at the bedside with those cultured in the laboratory, to determine if bedside plating provides a significantly better yield. Paired segments of 197 catheter tips from 92 surgical and medical ICU patients were evaluated prospectively. A total of 31 catheter tip cultures were positive for > or = 15 organisms per agar plate, ...

Due to the high uniformity demands, nickel deposition processes for producing reflector coatings often make use of dedicated plating cell configurations. Computer simulations can drastically speed up the trial and error stage for optimizing the plating cell design. In this paper, the nickel deposition distribution for a reflector application is simulated using the Elsyca PlatingMaster software ...

PURPOSE Complications in metacarpal fracture treatment increase in proportion to the severity of the initial injury and the invasiveness of the surgical fixation technique. This manuscript evaluates the feasibility of minimizing internal fixation construct size and soft tissue dissection, while preserving the advantages of stable internal fixation in a biomechanical model. We hypothesized that ...

astewaters from all processes w are collected by gravity flow into acid-alkali (rinses), chromate, cyanide, spenttstripping acids, and cleaner sumps. The acid concentrates and cleaner concentrates are gradually fed into chromate and acid-alkali (rinse) sumps, respectively. Cyanide destruction is achieved by oxidation with sodium hypochlorite whereas hexavalent chrome is reduced to trivalent chr...

Microtubes, are a basic component for a myriad of potential products. They are very small tubes (hundreds can fit ina human hair) that can be made from practically any material. Tubes larger than 1 micron diameter can be made withany cross-sectional shape desired. The significance of microtubes and microtnbe composites is that they provide theopportunity to miniaturize (even to the ...

The aim of this study is to describe the morphology of the posteromedial fragment in the setting of bicondylar tibial plateau fractures and to use it as a base for selection of the method of fixation. Twenty two -patients with bicondylar tibial plateau fractures -involving the posteromedial fragment were included in this study. Plain X- ray and computed tomogram (CT) were performed in all patie...

in this note we consider the notion of intuitionistic fuzzy (weak) dual hyper k-ideals and obtain related results. then we classify this notion according to level sets. after that we determine the relationships between intuitionistic fuzzy (weak) dual hyper k-ideals and intuitionistic fuzzy (weak) hyper k-ideals. finally, we define the notion of the product of two intuitionistic fuzzy (weak) du...

The mechanism of copper (Cu) voids formation from electro-chemical plating (ECP) followed by Cu chemical mechanical polishing (CMP) are studied in Cu dual-damascene interconnection. The formation of Cu voids at metal lines is the main problem that causes not only the failure of via-induced metal-island corrosion but also yield loss. The galvanic theory and Cu lifting mechanism are proposed to e...

Dual plating of complex, bicondylar tibial plateau fractures through an anterolateral and posteromedial approach is often performed to treat fractures complicated by a significantly displaced posteromedial fragment or a depression of the medial articular surface. The purpose of the present study was to (1) determine the deep infection rate of such fractures that are operatively fixed after allo...
