Elevated groundwater nitrate (NO3
-) concentrations in the Southern Willamette
Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to
declare a Groundwater Management Area (GWMA) in Spring, 2004. To better
understand direction of groundwater flow, groundwater age, and nitrate transport
pathways of the SWV we developed a steady-state...
Previous attempts to understand the factors affecting the energetic cost of locomotion have found a direct link between the energetic cost and the mechanical work done during periods when the limb is in contact with the ground. However, when the limb is not in contact with the ground during the...
Eleven sedimentary and volcanic rock units are mapped and described in the thesis area, and chronicle the dynamic geologic history of the Tillamook embayment from the Oligocene through the middle Mlocene. The
oldest unit is the Zemorrian to early Saucesian Smuggler Cove formation, a bathyal tuffaceous mudstone with some thin-...
Cicero wrote in Tusculan Disputations that we are born with the seeds of virtue which, if allowed to ripen, would lead us to a happy life (Cicero 227). However, as things are, we find ourselves in a world of "iniquity among a medley of wrong beliefs" that inhibits the ripening...
Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...
Because riparian canopy controls most energy inputs to stream
ecosystems, it directly affects the structure of aquatic food webs and the
ecological processes that govern interactions among trophic levels. This
study addresses the interdependence among riparian canopy, benthic
community structure, and the carrying capacity of high desert streams for
salmonid...
The cell survival curve is the only means by which to both qualitatively and
quantitatively assess morphologic alterations directly resulting from in vitro irradiation of
the cell. A ⁶⁰Co cell survival curve experiment has successfully demonstrated the
response of the AtT-20 clone mammalian cell line to the effects of gamma...
The study presents the results of a descriptive analysis of the skeletal remains of 66
individuals recovered from the Fuller and Fanning Mound sites, located on the Yamhill River,
Willamette Valley, Oregon, excavated in 1941-42 by W. T. Edmundson and William S.
Laughlin. The literature and original field notes have...
Few studies have examined the acute effects of
resistive-type exercise on lipid-lipoprotein profiles. This
study examined the acute effects of a single session of
circuit weight training (CWT) on plasma lipid-lipoprotein
profiles: triglycerides (TG), total cholesterol (TC), high
density lipoprotein cholesterol (HDL-C), low density
lipoprotein cholesterol (LDL-C), and the ratio...
