Aerobic Isolates in Hemovac Lines

Otolaryngology–Head and Neck Surgery, 1980
Positive aerobic isolates from hemovac lines were found in 41 of 68 patients (60%) who had major head and neck procedures requiring the hemovac drainage system during the postoperative period. When studied up to six days of placement, the number and the type of organisms in a hemovac system generally remained the same. A clue to impending infection was

Anaerobic isolates in hemovac lines

The Laryngoscope, 1977
AbstractSeventeen of 68 patients (25 percent) who required the use of hemovac drainage system after major head and neck procedures had positive anaerobic isolates. Co‐isolation of aerobic (94 percent) and other anaerobic (29 percent) microorganisms are common. There was an increased rate of positive anaerobic isolates with procedures requiring exposure

Perceived orientation of isolated line segments

Vision Research, 1968
Abstract This investigation is concerned with the spatial elaboration of retinal signals occurring in the visual system. Guided by the recent electrophysiological evidence that retinal orientation is among the first isolated spatial cues, we have used a psychophysical method to study the relationship between perceived orientation and geometrical ...

Lens-free in-line optical isolators

Optics Letters, 1999
We constructed a lens-free in-line optical isolator by embedding an isolator chip in a thermally expanded core (TEC) fiber without complicated optical alignment. The chip consists of two pairs of rutile wedges and garnet plates. We fabricated the TEC fibers by heating a single-mode fiber with a 200-mum outer diameter; low loss and a spot diameter as ...

Dual-band Branch Line Coupler with High Isolation Isolation Using Loaded Coupled Lines

2018 International Applied Computational Electromagnetics Society Symposium - China (ACES), 2018
A novel dual-band branch line coupler with high power division isolation using coupled lines is proposed. A conventional coupler loaded with quarter-wavelength open coupled lines is adopted to realize the dual bands. Each band has a high isolation due to the introduced transmission zeros.

Microstrip Ferrite Coupled Line Isolators

2006 International Conference on Microwaves, Radar & Wireless Communications, 2006
The double isolators using sections of ferrite coupled microstrip lines are demonstrated in a layered and planar approaches. The configurations are investigated both theoretically and experimentally at the frequency range 8-15 GHz. The better performances are observed for planar configuration that reports reflection losses -15 dB, isolation better than

Line Isolation Monitor

2017
Frequent fire accidents in operating theaters (OR) prompted the need for safety regulations in ORs. Electrical fires were the cause in many of these misadventures. This prompted the development of policies such as the safe practices in hospital operating rooms. Use of anesthetic gases in ORs worsened the hazard of fires.

Power-Line Isolation Devices

1987
A great deal of EMI comes from electromagnetic pollution of the AC power mains (11, 12). Among the more predominant sources of contamination of primary power are: common-mode noise due to radiated pickup, differential-mode noise due to other users on the same distribution line, dropouts, and interrupts.

Fiber-embedded in-line isolator

Journal of Lightwave Technology, 1991
A fiber-embedded optical isolator with a low forward loss has been developed. The isolator consists of thermally diffused expanded core fibers, laminated polarizers, and a Faraday rotation garnet. Backward and forward losses at 1.3 mu m wavelength are 44.0 and 0.9 dB, respectively. The isolator has a minute size, and its alignment is simple. >
