Rubber vibration isolators are used for vibration isolation of engines at high frequencies. To make a good prediction regarding the characteristics of a vibration isolator in the design process, numerical models can be used. However, for a reliable prediction of the dynamic behavior of the isolator, the rubber material parameters have to be known. In practice the material parameters have to be ...

To compare the performance of the BACTEC 13A (Becton Dickinson, Sparks, Md.), BACTEC MYCO/F LYTIC (Becton Dickinson), BacT/ALERT MB (bioMérieux, Durham, N.C.), and ISOLATOR 10 lysis-centrifugation (Wampole Laboratories, Cranbury, N.J.) systems for detection of mycobacteremia in adults, we inoculated 5-ml aliquots of blood from patients with suspected mycobacteremia into the bottle or tube requi...

Leptin directly suppresses the activity of orexigenic neurons in the hypothalamic arcuate nucleus (ARC). We examined c-Fos-like immunoreactivity (CFLIR) as a marker of ARC neuronal activity in db/db mice devoid of the signaling form of the leptin receptor (LRb) and s/s mice that express LRb(S1138) [which is defective for STAT3 (signal transducer and activator of transcription) signaling]. Both ...

A controlled clinical comparison was made of the Isolator (Wampole Laboratories, Cranbury, N.J.) and the Septi-Chek Release bottle (Roche Diagnostics, Nutley, N.J.). From 6,345 blood culture sets fulfilling minimum criteria for volume of blood cultured, 840 strains were isolated, of which only 691 (82%) were considered to be representative of bloodstream infection according to Centers for Disea...

A ring isolator is demonstrated for the first time by directly bonding a cerium-substituted yttrium iron garnet (Ce:YIG) onto a silicon ring resonator using oxygen plasma enhanced bonding. The silicon waveguide is 600 nm wide and 295 nm thick with 500-nm-thick Ce:YIG on the top to have reasonable nonreciprocal effect and low optical loss. With a radial magnetic field applied to the ring isolato...

The sensitivity and time to detection of Brucella melitensis by the BACTEC 9240 and the Isolator blood culture systems were compared in a prospective volume-controlled study. Blood sample aliquots, obtained from children with suspected brucellosis, were inoculated into a BACTEC 9240 Peds Plus bottle and into an Isolator 1.5 Microbial Tube. Overall, 122 pairs of blood samples for culture were ob...

Experimental and analytical studies of a seismically isolated five-story model structure are conducted to understand the behavior of a novel uplift-prevention Friction Pendulum isolator. Shake table testing on the earthquake simulator at the University at Buffalo involves a number of simulated ground motions with a variety of frequency content and amplitude. A comprehensive analytical model is ...

We present an integrated optical isolator based on adiabatic wavelength conversion in microcavities. The isolator uses a time-division sampling method to ensure complete isolation of optical pulses with an extinction of 24 dB. ©2009 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (230.3240) Isolators.

This paper describes a type of isolator which is based on Solid And Liquid Mixture (SALiM) for vibration isolation and shock absorbing. The nonlinear force-displacement relation of the isolator is established. Using the precise integration method, the primary responses in time domain are evaluated to study the isolator’s property. Index terms — Solid and Liquid Mixture, Vibration Isolation, Vib...
