The 10-ml Isolator system (E.I. du Pont de Nemours & Co., Inc., Wilmington, Del.) was compared with the BACTEC 16A-17A nonradiometric resin system (Johnston Laboratories, Inc., Towson, Md.) for isolation of organisms from 6,839 paired blood cultures. Equal volumes of blood (6 to 10 ml for each Isolator and 3 to 5 ml for each BACTEC bottle) were cultured in parallel in the two systems, and 600 i...

Synovial fluid specimens obtained from patients with arthritis were plated onto solid media (conventional cultures) or inoculated into an Isolator 1.5 microbial tube (Isolator cultures), and the yield and time to detection of organisms were compared. Overall, 144 specimens obtained from 137 patients were processed, and 31 (21.5%) cultures obtained from 29 patients were positive by at least one ...

Passive vibration isolator with lower natural frequency has always been a challenge due to structural integrity issues. This study presents the use of RSM statistical tool analyze and optimize mechan-ical responses BCC lattice structure for in passive application. The optimization was done obtain low stiffness but high yield stress optimum load-bearing capability unit cell size strut diameter d...
