Sentences with phrase «radiofrequency fields»

Cooled to extremely low temperature, these «superconducting» cavities allow radiofrequency fields to boost electron energies without electrical resistance — a crucial property for the acceleration of electrons at a rate of up to a million bunches per second.

«Even with generous assumptions about the properties of the radicals, we predict tiny effects of these radiofrequency fields, and the main conclusion that we come to is that the current understanding of the radical - pair model can't explain any of the reported behavioral results,» says Hore.

And regarding the non-thermal effect, they hold that «to date, research does not suggest any consistent evidence of adverse health effects from exposure to radiofrequency fields at levels below those that cause tissue heating.»

Not exact matches

«The radical - pair mechanism of magnetoreception is still just a hypothesis, and arguably the best evidence we have for it so far is the effect of time - dependent radiofrequency magnetic fields on the ability of migratory birds to detect the direction of the Earth's magnetic field,» says senior author Peter Hore, an Oxford biophysical chemist specializing in magnetic influences on chemical reactions.

However, University of Oxford researchers report October 3 in Biophysical Journal that the current form of this «radical - pair mechanism» is not sensitive enough to explain the disruption of the avian magnetic compass by certain radiofrequency magnetic fields, raising new questions about this popular example of quantum biology.

«The use of a radiofrequency - driven magnetic field is a big advance in remote gene expression because it is non-invasive and easily adaptable,» says Dordick, who is Howard P. Isermann Professor of Chemical and Biological Engineering and vice president of research at Rensselaer.

A drive for high - field MRI is mediated by the benefits of better image resolution However, tissue heating becomes substantial at higher fields due to an increase of the radiofrequency energy absorption.
