The purpose of this study was to investigate what older adults with severe, moderate, or no mobility limitation consider motives for and barriers to engaging in physical exercise. Community-dwelling adults (N=645) age 75-81 years completed a questionnaire about their motives for and barriers to physical exercise and answered interview questions on mobility limitation. Those with severely limite...
PURPOSE to examine the combined effect of cohabitation status and social participation, respectively, and socioeconomic position on onset of mobility limitations in a prospective study among older Danes. DESIGN AND METHODS logistic regression analyses with combined exposure variables were performed in a study population of 2,839 older men and women from the Danish Intervention Study on Preven...
We present investigations on beam instabilities that have been observed at 2.0 GeV and 2.5 GeV in the PLS storage ring. Stored beam currents of 2.0 GeV in the ring has been mainly limited by coupled-bunch instabilities. We have investigated dependences of the coupled-bunch instabilities on betatron tune, chromaticity and rf cavity temperatures at 2.0 GeV. 450 mA beam could be stored at 2.0 GeV....
tau.amegroups.com © Translational Andrology and Urology. All rights reserved. The commentary by Drs. Garrido, Rivera and Luján (1), in response to the practice recommendations by Agarwal et al. (2), is a valuable addition to the debate on sperm DNA fragmentation (SDF). We want to supplement their information as well as provide our opinion on several important points raised by the authors. The a...
Contrary to the general expectation that performance of a plasma focus would progressively improve with progressive reduction of its static inductance Lo, a recent paper suggests that there is in fact an optimum Lo below which although the peak total current increases progressively the pinch current and consequently the neutron yield of that plasma focus would not increase, but instead decrease...
