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 ...

Since the early ideas of internal fixation, many different concepts and techniques have been developed for the use in fracture surgery. Each technique has been welcomed by many with excitement while others have suggested caution, locked plating is no exception. Since its advent over 15 years ago many have viewed this as a violation of the strict AO principles of anatomic reduction and rigid fix...

PURPOSE To evaluate the neurological recovery and fusion rate of patients with myelopathy who were treated with anterior corpectomy and anterior cervical plating. METHODS The results of 17 cervical myelopathy patients who underwent decompression and anterior cervical plating were retrospectively reviewed at a mean follow-up of 2 years. RESULTS By Kurokawa score, 82.4% of patients showed exc...

Advanced hybrid microelectronics require high performance packaging materials and components. Alumina, the most widely used ceramic material in microelectronics, is being replaced by new high performance materials such as aluminum nitride (AlN) and beryllia (BeO). AlN's thermal conductivity is an order of magnitude greater than alumina and it has a thermal expansion coefficient very close to si...

Tumor cells from a human melanoma xenograft show better colony growth and plating efficiency in soft agar when incubated in a 5% O2 atmosphere that at a higher concentration of 20% O2. Exposure to low drug concentrations under a 20% (but not 5%) O2 atmosphere stimulated plating efficiency. Enhanced sensitivity (4- to 20-fold) to a variety of chemotherapeutic agents was seen in cells incubated u...
