Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

The technique of principal component analysis has been applied to spectra obtained by thermally stimulated discharge current measurements on polyimide films. The films had been aged by gamma irradiation followed by long term exposure to elevated temperatures. The relationship between the aging history and the changes observed in the principal component values derived from the spectra are discussed.
