Impedance spectroscopy is a method of modeling materials with equivalent circuits to determine electrical properties, such as the resistivity and the dielectric constant. We explore impedance spectroscopy, both theoretically and experimentally through applying the method to samples of BaCuS1-xSexF. Grain boundary effects were dominant in the results, and although they...
Predicting agronomic rates is important to derive optimum economic and environmental benefits from biosolids fertilizer applications. We conducted this research to 1) evaluate dryland wheat response to biosolids applications over a range of climate zones in the Pacific Northwest and 2) compare agronomic application rates predicted from yield curves with...
This report documents vegetation monitoring and mapping conducted by Green Point Consulting during summer 2006 at six tidal wetland restoration and reference sites in the Siletz Bay National
Wildlife Refuge of Oregon, and the upper Yaquina River estuary (near Toledo, Oregon). Vegetation at all sites except one had been monitored...
This report was derived from field data collected by personnel of the US Forest Service (USFS) and Oregon Natural Heritage Program (ONHP). The area examined encompasses four National Forests (Gifford Pinchot, Willamette, Mt. Hood, and Siuslaw) and two Bureau of Land Management Districts (Salem and Eugene). It does not include...
Ruchi Glades is proposed for designation as a Research Natural Area. It is located on the upper slopes of Oregon Caves National Monument which is administered by the National Park Service. Ruchi Glads has an impressive diversity of plant communities for such a small area. The Oregon Natural Heritage Plan...
