We tested the hypothesis that elevated sympathetic tone is responsible for lower peak vasodilation after single muscle contractions in older adults. Young (n = 13, 7 men and 6 women, age: 27 ± 1 yr) and older (n = 13, 7 men and 6 women, age: 69 ± 2 yr) adults performed single forearm contractions at 10%, 20%, and 40% of maximum during 1) control, 2) sympathetic activation via lower body negativ...

This work examined teakwood and parawood in wood/poly(vinyl chloride) composite (WPVC) materials under UV-weathering seawater immersion. The mechanical properties as well anti-fungal anti-algal performance were considered. Teakwood (a rubberwood product) WPVC at ratios of 0:100, 20:80, 40:60, 50:50, 60:40, 80:20, 100:0 investigated. ageing periods 0 to 32 days immersion 90 studied. Aspergillus ...
