In an effort to fill an existing need two small electric service
vehicles were designed, constructed, and tested. The first
acted as a feasibility study and the second as a design prototype.
The vehicles had low cost and the capability of being fabricated by
their users as two main design...
This research focuses on events surrounding the activities of Battery
Freeman, a coastal defense facility constructed within the earthworks of "old" Fort
Stevens near Astoria, OR, in 1900 and destroyed in 1939. Archival data are used
in conjunction with nearly 5,000 artifacts that were recovered from archaeological
excavations in 1989...
A small mammal inventory of occurrence and relative abundance was conducted in riparian and upland habitats in six segments along the lower Columbia River from the river mouth to McNary Dam (river mile 292) during 1974 and 1975 by removal trapping on standardized trap lines. Analysis of variance was used...
Seedlings from 25 provenances of Abies grandis and Abies
concolor were studied at two plantations, 12 at Philomath, Oregon,
and 13 at Camino, California. Native seedlings were studied at four
of the provenances' field sites. Stomatal infiltration pressure
measurements and plant moisture stress measurements were made
throughout one summer on...
Three closely related isolates belonging to the A₁ serotype of infectious pancreatic
necrosis virus (IPNV) were selected for comparison, to provide insight into the nature of
variation in the virulence of IPN viruses. Brook trout fry (Salvelinus fontinalis) were
experimentally infected with the three isolates by immersion. Cumulative mortalities over...
Under the reauthorized Magnuson-Stevens Act (MSRA), US fisheries management councils must specify an annual catch limit (ACL) for each managed species and institute accountability measures (AMs) to ensure that actual harvest will not cause the stock to be overfished. While the details of implementation are still being developed, a set...
In this thesis, I read the teachers in four mid-century Victorian novels--Charles Dickens' David Copperfield (1850) and Hard Times (1854), Thomas Hughes' Tom Brown’s Schooldays (1857) and Charlotte Brontё's Villette (1853)-- within the context of mid-century English educational debate in an effort to explicate the ways in which these characters...
Cascade Locks, Oregon, has chosen tourism as a means of
revitalizing its economy with its 1) accessibility to Interstate
80N, 2) attractive location in the Columbia River Gorge, and 3) availability
as a source of needed services (food and fuel). The Port
of Cascade Locks has financed the Marine Park,...
Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...
