Algae can be used in a variety of wastewater systems to capture nutrients while fixing carbon dioxide from the atmosphere. I conducted field trials at three locations in Oregon with both corn and potato crops to assess the agronomic value and environmental impact of using the resulting algal biomass as...
It is no longer possible in any area of the United States to formulate
water resources plans for single purpose projects as has been
done in past years. No longer can one of our greatest natural resources,
water, be used solely for navigation, power generation,
irrigation, or controlled for reducing...
The vegetation in Yosemite National Park changed during the 20th century and may change in the 21st century in response to climate change. Vegetation surveys made during the 1930s and the 1990s provide benchmark records separated by 60 years. This study uses the MC1 dynamic global vegetation model to forecast...
Pharmacokinetic parameters for theophylline and
dyphylline were evaluated in horse cerebrospinal fluid
(csf) and plasma. Pharmacokinetic parameters did not
differ significantly (p > 0.05) at the same dose for
either drug when administered alone or concomitantly.
Theophylline and dyphylline penetrate horse csf to
produce approximately 1/2 the concentrations found in...
Nursery-grown seedlings are critical for attaining reforestation and restoration success in many ecosystems, including mixed-conifer forests in the Northwest, which is the native range for Douglas-fir (Pseudotsuga menziesii). Seedling establishment after planting depends on coordinated responses in seedling growth, physiology, and hydraulic function. The chapters in this dissertation review growth...

Despite recent efforts to improve site safety, construction still accounts for a disproportionate injury and illness rate. According to the 2007 injury and illness data released by the National Safety Council, the construction industry has a fatality and disabling injury rate that is approximately three times higher than the all-industry...
The indiscriminate release of fecal bacteria to the environment
can present a public health hazard when pathogenic species gain access
to drinking and recreational water sources. The extent of bacterial
contamination of surface and ground waters associated with animal
production units and waste application areas seems largely dependent
on the...
