The Isolator 10 lysis-centrifugation blood culture system (E. I. du Pont de Nemours & Co., Inc., Wilmington, Del.) and the BACTEC 16B-17D radiometric resin system (Johnston Laboratories, Inc., Towson, Md.) both remove antimicrobial agents from the blood for culture. We compared these two systems for recovery of aerobic bacteria, facultatively anaerobic bacteria, and yeasts. A total of 5,000 blo...

Abstract Background The resonant-frequency-tunable vibration isolator based on Shape Memory Alloys (SMAs) combines the priority of passive and active isolators, expands its engineering application, improves efficiency isolation. However, special characteristics SMAs complexity result in difficulty finite-element analysis. Methods This article employs ABAQUS subroutine presents analysis for this...

Soft storey buildings are characterized by having a storey which has a lot of open spaces. This soft storey creates a major weak point in an earthquake. Since soft stories are classically associated with retail spaces and parking garages, they are often on the lower stories of a building, which means that when they collapse, they can take the whole building down with them, causing serious struc...

Wire rope isolator is widely used in the field of vibration isolation and shock resistance naval equipment. To overcome shortcomings poor tensile performance traditional wire isolator, a new biaxial compression was designed, characteristics isolators spherical were tested using test methods. By conducting comparative experiment, difference are studied. The frequency sweep results ...

The efficiency of the 10-ml Isolator (E. I. du Pont de Nemours & Co., Inc.) for recovery of pathogens from blood was compared with that of BACTEC 6B and 7C media (Johnston Laboratories) by using 4,195 cultures from 1,662 patients. During the first phase of the study, BACTEC bottles were inoculated with 3 ml of blood; in the second phase, bottles were inoculated with 5 ml. The objectives were to...
