Twenty sites of uniform topography and soil were select ed in the
montane forest found on the East flank of the Central Oregon Cascades.
These sites were located along a vegetational gradient composed of
five plant communities: Abies/Pachistima, Pinus/Ceanothus, Pinus
Arctostaphylos-Purshia, Pinus/Purshia/Festuca, and Juniperus
Festuca. An attempt was made to...
Seven sites of uniform topography and soil were selected within
a self perpetuating ponderosa pine forest found on the eastern
flank of the central Oregon Cascades. These plots were located along
a vegetational gradient caused mainly by an orographic rain shadow.
Data gathered included density, frequency, and cover for all...
Recent changes in the historiography of American Transcendentalism
have inspired a reappraisal of the relationship between the Transcendentalist
movement in New England and the pietistic wing of the Unitarian church. This
thesis explores this reappraisal through a close reading of selected writings by
Henry Ware Jr. in juxtaposition to the...
The North Pacific humpback whale (Megaptera novaeangliae) population has been increasing at an average annual rate of ~6% since the early 1990s. In northern Southeast Alaska alone, there are now more whales than estimated for the entire North Pacific several decades ago. An understanding of how this growing population is...
The steroid hormone estrogen plays a crucial role in regulating certain mammalian tissues, especially female reproductive systems. Estrogen effects physiological changes in the cell by altering transcription activity for certain target genes, as a consequence of interactions between estradiol-17β (E2) and its nuclear receptor (nER). This mechanism of cellular control...

The research undertaken in this study deals with three topics related to the prediction of thermodynamic properties of electrolytes in aqueous solutions. In the first, Pitzer ion interaction parameters for 304 single electrolytes were evaluated from recently published osmotic coefficient data at 25°C by using multiple regression analysis to fit...
Forest composition in Paraguay has been in a state of change for the past half century due to land management practices, forest fragmentation, and deforestation for agriculture. How these factors affect dendrological diversity and wood anatomy in Paraguay is not well understood. This thesis documents Paraguayan forest composition on the...
The effects of possible operating variables such as flow rate, surface temperature, bulk temperature, solids contents, sulfate addition and pH on the fouling of sulfite spent evaporators were studied. The study pointed out that the Ca⁺⁺ concentration difference between heated surface and bulk is the most important factor for fouling...
Nathaniel Hawthorne lived and wrote in an age of reform efforts, and the progressive movement with which he was most familiar was Transcendentalism. However, he was not sympathetic with Emerson's idealism, a sentiment which comes out in his fiction in way of critique. Throughout Hawthorne's work there is an emphasis...
The United States nuclear industry is under
significant public pressure to close the nuclear fuel
cycle. Closing the fuel cycle will require that nuclear
waste, fission products and transuranics, except plutonium
(actinides), be disposed of by permanent burial. The
actinides can be buried with the fission products, but this
will...
