Great Lakes coastal wetland communities are threatened by the impacts of invasive plants on ecosystem function and biodiversity. What allows invasive plants to become dominant in invaded communities can be hard to define and context-dependent. Traits associated with invasion success in wetland systems – rapid vegetative growth, competitive superiority in...
Using Southeast Asian hardwood veneers for exterior plywood siding
has caused problems because some species produced quality plywood while
other species produced plywood which delaminated soon after being put
in service in exterior exposure. This study attempted to improve the
durability of glue bonds of some Southeast Asian hardwood veneers...
This research related resin synthesis variables of phenolformaldehyde resins to their chemical content and reactivity. The study was part of a larger project correlating resin properties to their performance as plywood adhesives. Formaldehyde-to-phenol and Na0H-to-phenol mole ratios were examined within the ranges used commercially. I also examined various proportions of...
Primary disease gradients of wheat stripe rust, caused by the aerially dispersed fungal pathogen Puccinia striformis, were measured in Madras and Hermiston, OR in the springs of 2002 and 2003. Disease foci were created by inoculating a 1.52m x 1.52m area in each of three replicate field plots (6.1m wide...
A sample of 1,003 women, age 22 in 1983-84 and age 27 in 1988-89, were
selected from the National Longitudinal Survey of Youth. Personal, familial, and
geopolitical predictors of alcohol consumption were evaluated at each time period and
longitudinally. The study integrated macro- and micro-level influences to determine
their influence...
