The aim of this study was to compare the biomechanical properties of medial and lateral plating of a medially comminuted supracondylar femoral fracture. A supracondylar femoral fracture model comparing two fixation methods was tested cyclically in axial loading. One-centimetre supracondylar gap osteotomies were created in six synthetic femurs approximately 6 cm proximal to the knee joint. There...

The authors report a method for monitoring, control, and end-point detection of electroplating in nanostructures. The method is demonstrated on nickel plating into polymer molds, which is an important process in the fabrication of soft x-ray zone-plate diffractive optics. The lack of reproducibility presently limits the achievable nickel aspect ratio and, thus, reduces the zone-plate diffractio...

In this talk, we report a research work on fabrication and metallization of high aspect ratio polymer microstructures fabricated using UV lithography of SU-8 on silicon substrate. Electroless plating of metal film on both the top and sidewall surfaces of microstructures were achieved while the silicon substrate was not plated. The primary chemical mechanisms and possible applications were also ...

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 ...
