Tree diameter, understory plant cover, seedling density, elevation, aspect, and slope steepness are recorded for 51 forest stands dominated by Tsuga mertensiana (Bong.) Carr. along the eastern portion of the central Oregon Cascades. Species dominance based on prominence values for
trees and percent cover for shrubs and herbs are correlated...
The properties of evaporated aluminum-oxide films were investigated. The characteristics of MOS devices
made with single-layer aluminum-oxide films and double-layer
films which were made by evaporating aluminum oxide
over thermally-grown silicon dioxide as gate insulation
have been investigated. Vacuum-evaporated aluminum oxide
has features which are suitable for fabricating MOS devices....
This report presents the findings of a sediment analysis
program formulated to determine the flushing potential
of various shaped small boat marina basins. Chemical tests
regarding volatile solids, Kjeldahl nitrogen, grease and
oil, and sulfides were performed with the results compared
to established sediment quality criteria. These results
were used...
Barth's theory of transactional analysis is applied to the
community of Tiller, Oregon and its reaction to a development proposal.
Community behavior patterns vis-a-vis the development proposal are
examined from a processual point of view to determine how these
patterns are generated.
The community's history and contemporary situation are described....
The extent of the competitive effect of wild oats on winter wheat
yield was estimated in field studies on three commercial wheat farms in
the Willamette Valley. The morphological development of the wild oat
plants was also documented.
Wild oats were removed from stands of wheat in six different treatments;...
This thesis is an ethnohistoric study of the water rights of the Yakima Confederated Tribes. The study considers the water rights issues of the Yakimas from the cultural viewpoint at the time of European contact to the present legal and political situation. It traces the many obstacles the Yakimas have...
The Willamette River Basin, Oregon, viewed in terms of a cultural-ecological system, has been subject to three phases of cultural development: hunting and gathering, agrarian, and industrial-urban. Each population base has employed a technology to exploit the environment to the extent that its patterns of culture would allow. This technology...
Kelso's theory of Biocultural Evolution states that as culture evolves, the variation between groups diminishes while the variation within groups increases. The theory is tested with stature, cephalic index and nasal index. Means and standard deviations for these traits are examined for 237 ethnic groups. The groups are organized according...
The antiquity of the Northwest Coast Indian pole is the subject
of a great deal of controversy. A few viewpoints referring to that
topic are given. The symbolic value of the Kwakiutl totem pole is
examined with respect to art, style and culture; more generally
"primitive" art is considered as...
Samarium-neodymium data for authigenic ferromanganese
sediments from the oceans indicate that the Atlantic, Pacific, and
Indian Oceans each have a distinct range in Nd isotopic composition,
all of which are far less than ¹⁴³Nd/¹⁴⁴Nd ratios of source rocks with
oceanic affinities. Direct measurements of the Nd isotopic composition
of seawater...
