The Schwarz-Christoffel transformation is used to map simply connected polygons onto the upper half plane and can be applied to problems in which the validity of Laplace's equation is assumed. However the direct integration of the resulting complex integral is often not possible and some approximate method must be used....

Detailed phytosociological and physical data were gathered from six grass-fern balds in the Oregon Coast Range, Monmouth Peak, Grass Mountain, Prairie Peak, Roman Nose Mountain, Tyee Mountain, and Saddle Mountain. Panchromatic and color infrared air photography guided sampling within individual balds. The resultant floristic data was manipulated by a Braun-Blanquet...

There are few studies on sea lion health and...
A literature review for a research project being done in partnership with the Oregon Department of Fish and Wildlife and the Columbia River Intertribal Fish Commission, which will look at non-breeding California sea lion males in the Columbia River Basin that have been preying on migratory salmon. This will be...
