We have recently shown that bimorph piezoelectric PVDF films induce formation of periosteal bone in vivo and attributed this phenomenon to a piezoelectric effect. In the present study films were implanted in rabbits to encircle the femoral diaphysis. Specimens obtained after 6 and 12 days were ...
Hazard control measures can be categorized as either administrative procedures, personnel protective equipment (eye protectors, respirators, gloves, etc.), or engineering controls for the laser and environment. Engineering controls, although typically more costly, are generally considered more reliable, sin...
The control and management of hazardous wastes are truly among the most important challenges of our times. Environmental engineers play crucial roles in reducing the amount of hazardous substances produced, treating hazardous wastes to reduce their toxicity, and applying sound engineering controls to redu...
