The shells are preferably porous allowing for nutritional support of the graft and limit the thickness of the graft to no more than a few millimeters. Thus nutrients and metabolic by-products transport by diffusion alone is sufficient to maintain grafted metabolism in the critical phase before re...

Hawaii has a brutal climate for windows and window hardware; high rise condos add the complexity of higher stresses, increased wind loads, and inherent difficulties in access including the potential need for gantry or scaffolding. Windows designed solely for residential use are simply are not ...
PNR is a nucleus replacement manufactured by TranS1 which is implanted through a trans-sacral approach used for L5-S, but sometimes together with L4-5. It consists in a system of titanium screws that are anchored to the upper and lower parts of the vertebral body, and a membrane in the ...
The whole process began with scaffolding being set up by Chicago Scaffolding, which allowed our Smart Roofing sheet metal crews to safely and efficiently access the steeple. After tearing off the existing damaged paneling, we replaced damaged wood, installed new high temperature underlayment, and beg...
;SOLUTION: Necessary regions 41, 42, and 3 for scaffoldings for each of parts 21, 22, and 23 to be installed are defined, and the parts and the regions are arranged, in order, according to a predetermined order. Thereafter, by using genetic algorithm, production processing for a ...
Applications of reverse engineering can range from the production of molds and dies from wood or clay models to the creation of replacement parts from worn existing machinery. In reverse engineering, both contact and non-contact ... Chan, Vincent Harry. 被引量: 11发表: 1999年 Optimal maintenanc...
