Senecio jacobaea (tansy ragwort) is a poisonous plant responsible
for livestock deaths in the Pacific Northwest. Horses and cattle are
susceptible, while sheep are resistant to the toxic action of the
pyrrolizidine alkaloids which the plant contains. Hepatic enzymes
are responsible for the biotransformation of pyrrolizidine alkaloids
into tissue damaging...
The average size and age of chinook salmon (Oncorhynchus
tshawytscha) caught in commercial fisheries along the Pacific Coast
of North America have decreased substantially in this century. These
declines might be caused in part by changes in size and age at
maturity within the stocks contributing to those fisheries. Upriver...
It has been suggested that cellular damage from oxygen radicals is one of the processes leading to cardio-vascular disease and cancer. Natural antioxidants prevent uncontrolled oxidative reactions by decreasing molecular oxygen levels, scavenging chain-initiating and chain-propagating free radicals, chelating metals, or decomposing peroxides. Beer is rich in antioxidants, derived both...
All parents experience some problems with their children and may
look to various parenting resources for guidance and reassurance
(Stoltz, 1967). The literature on the problems parents experience,
including tantrums, bedwetting, whining/crying, has not
comprehensively explored the range and co-occurrence of child
behavior problems across all ages (Kanoy and Schroeder,...
There is a connection between science and art. This study is specifically looking at the connection between soil science, art, and biochemistry. The traditional display of research in the sciences is in a written form such as a manuscript or journal article. To challenge this traditional presentation of scientific knowledge...
A simple debris-slide model, employing a digital elevation model (DEM) and geological data, was used in a geographic information system (GIS) to map slope stability in the Andrews Experimental Forest, located in the western Cascade Range in Oregon, USA. To evaluate the contribution of error in elevation to the uncertainty...
High water temperatures in rivers have detrimental effects on riverine water quality and ecology. In this study, two river temperature models, within the agricultural watershed model Soil and Water Assessment Tool (SWAT), were investigated for their ability to simulate water temperatures accurately throughout the year. The original temperature model within...
Cataract is a leading cause of blindness throughout the world, yet the fundamental biochemical causes are unknown. A rodent model of the biochemical processes is selenite cataract. This cataract shows some of the features of human cataracts such as increased lens calcium, proteolysis of proteins, and insolubilization leading to lens...
