Other applications eventually may include detection of chemical weapons and land mines, patient breath analysis for medical diagnosis or monitoring, and industrial detection of leaks in subterranean pipes or storage tanks, the c...Veterans in better health than other residents of nursing homes, new test for evaluating tinnitus
...sure hearing thresholds and loudness matches at 13 frequencies and 5 repeated pitch matches with the new system. Investigators assert that standardized assessment of tinnitus is essential, so that the perceptual attributes of the disorder can be quantified.

"But, until we started using satellite imagery, we could only guess at the coupling and data quality in advance of an actual survey.

... trigger bladder contractions. The team found that frequencies in the range of 20 to 40 cycles per second work best for bladder emptying. "It was a surprise that no one had figured this out yet. But now that we understand the whole picture, we can pursue an engineered solution to help people restore bladder cont...When the brain, not the ears, goes hard of hearing
...ost people gradually lose the ability to hear high frequencies as they age, the feedback and timing problems account for many of their complaints about hearing, Frisina says. "These problems with the aging brain, which nearly everyone experiences, are on top of problems with our ears, which you may or may not h...Study finds drug eluting stents as effective as vascular brachytherapy in preventing restenosis
... demographic variables, angiographic variables and frequencies of in-hospital and 6-month adverse events between patients who received SES or VB for in-stent restenosis. "We found SES as treatment for ISR is at least equivalent, if not superior, to VB.

However, within these frequencies of light, the oxygen-carrying molecules within red blood cells known as hemoglobin absorb light to an extent based on their oxygen content -- giving the researchers a reliable indicator of cerebral oxygenation. Researchers place a fiberoptic probe ag......ng an electrical current through the needles. High frequencies of stimulation also had no effect, but low frequencies lowered increased blood pressure by as much as 40 to 50 percent. Overall, the researchers found that...
