Oxygen storage capacities of CeOz, Ce02/A1203, and PMiCe0,/A120~, measured by a pulse injection method, are affected by pretreatment temperature, pulsing temperature, partial pressure of CO, presence of precious metals (PM), and the concentration of CeOz on alumina. They are lowered by higher pretreatment temperature but increase with the pulsing temperature in the range of application. At a pu...

Whereas intact postharvest avocado (Persea americana Mill.) fruit may take 1 or more weeks to ripen, ripening is hastened by pulsing fruit for 24 h with ethylene or propylene and is initiated promptly by cutting slices, or discs, of mesocarp tissue. Because the preclimacteric lag period constitutes the extended and variable component of the ripening syndrome, we postulated that selective gene e...

Pulsed dc power supplies provide enabling capability to dielectric reactive sputtering applications due to their ability to reduce or even eliminate arcing during the deposition process. As this technology matures there has been increasing interest in the semiconductor, optical and industrial coating industries to use pulsed-dc sputter supplies for difficult to deposit films. The fundamental be...

Perceptual voice analysis is a subjective process. However, despite reports of varying degrees of intrajudge and interjudge reliability, it is widely used in clinical voice evaluation. One of the ways to improve the reliability of this procedure is to provide judges with signals as external standards so that comparison can be made in relation to these "anchor" signals. The present study used a ...

OBJECTIVE To test whether people who report being sensitive to mobile phone signals have more symptoms when exposed to a pulsing mobile signal than when exposed to a sham signal or a non-pulsing signal. DESIGN Double blind, randomised, within participants provocation study. SETTING Dedicated suite of offices at King's College London, between September 2003 and June 2005. PARTICIPANTS 60 "...
