The importance of physical activity is well documented (Haskell et al., 2009a; McReynolds & Rossen, 2004; Steinbeck, 2001). Despite physical activity’s benefits, many individuals are not meeting current weekly physical activity guidelines recommending ≥ 150 minutes of moderate or ≥ 75 minutes of vigorous aerobic physical activity and 2 or...
There is a known relationship between total physical activity (PA) and weight status in children; however, there is a paucity of data examining the prospective relationship between school day PA and obesity among rural elementary school children. A large number of cross-sectional studies have demonstrated that higher levels of PA...
The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...
Present day data processing technology requires very high speed signal processing
and data conversion rates. Traditionally, these circuits have been implemented in silicon
