Strawberry plants infected with June yellows and witches'-broom
disease were grown in a mist chamber and treated with varying concentrations
of oxytetracycline. Treatment with 50 ppm oxytetracycline
produced phytotoxicity effects in strawberries infected with June yellows.
However, treatment with 10 ppm oxytetracycline resulted in a
significant (one percent level) increase...
Cotoneaster is a genus of ornamental landscape plants commonly affected by fire blight. Fire blight is a disease caused by the bacterial pathogen, Erwinia amylovora (Burrill) Winslow et al. that attacks a wide range of taxa in the apple subfamily (Maloideae; Rosaceae). To assess susceptibility of species and identify potential...
This dissertation is a qualitative secondary content analysis of clinical records collected for the Spokane Safe Start Project in Spokane, Washington, a program designed to offset trauma in children exposed to domestic and intimate partner violence (IPV). The Centers for Disease Control and the World Health Organization have identified intimate...
A sample of fish remains from two late-prehistoric archaeological sites on the central coast of Oregon were analyzed to partially evaluate two models of aboriginal subsistence-settlement systems. One model is based upon ethnograhpic data, primarily Drucker's (1939), for Yakonen speakers collected in the late 19th and early 20th centuries. The...
This thesis was to develop a bone artifact typology for the Oregon coast. This typology was used to test the hypothesis that different geographical regions of the Oregon coast would have different artifact assemblages associated with them. These regions, identified by geologist from landform changes, have been defined as: region...
In 1982 a protohistoric archaeological site along the Applegate River in southwest Oregon was excavated by Oregon State University Department of Anthropology. Three housepits and a possible menstrual but were uncovered with lithic, faunal, and archaeobotanical elements recovered from house floors and hearths. Seven botanical taxa were represented by carbonized...
The ambient temperatures and humidities required for contrail formation
and persistence are determined from in situ measurements during the
Subsonic Aircraft: Contrail and Cloud Effects Special Study (SUCCESS) experiment.
Ambient temperatures and water vapor concentrations were measured
with the meteorological measurement system, a laser hygrometer, and a cryogenic
hygrometer (all...
This study examines the spatial and temporal distribution and life history of the "offshore" component of the Northeastern Pacific spiny dogfish (Squalus acanthias) population. Distribution was examined in relation to latitude, depth, the Columbia River plume and large-scale climate changes. Fishery and survey data indicate that the Northeastern Pacific spiny...
The Great Salt Lake is typical of Great Basin
and other arid land saline lakes in morphological and
chemical characteristics. As with other terminal
lakes, the level of Great Salt Lake is determined by
the variable weather patterns that are typical of
arid and semi-arid regions. Because of it's flat,...
