Objectives: To identify the perceptions of community hospital physicians on computerized physician order entry. Design: Multi-method approach consisting of a mail survey of 659 community hospital physicians with active admitting privileges at three PeaceHealth, Inc., along with follow-up personal interviews with stratified random selection from completed survey. Measurements: Perceptions were...
Ponderosa pine trees exhibiting large oval scars on
their trunks are found in northeastern Oregon. Patterns
in the occurrence and morphology of the scarred trunks
raise questions of archeological interest. Examination of
ethnographic sources from the Pacific Northwest indicate
that the bark of ponderosa pine was peeled to obtain the...
It was observed that certain myoelectric surface
potentials are of a pulse nature. The pulses have nearly
the same exact waveshape, but are asynchronously
repetitive.
Physiological evidence indicated that myoelectric
pulses are concurrent with the activity of a small unit
of organized muscle fibres (motor unit). The electrical
activity of...
An investigation has been made of several physical parameters of the effluent plume of the Columbia River as it enters the Pacific
Ocean. Radioactive material in trace amounts enters the Columbia River from the Hanford nuclear reactors at Richland, Washington. One of these nuclides, chromium -51, has been used to...
This thesis reports on an investigation of flow patterns in
shallow geothermal wells in Klamath Falls, Oregon, Although
wells have been extensively used in the area, the exact nature of
the flows in the wells has not been characterized.
Flow characterization is a principal object of this study.
Horizontal crossflows...
Genetic studies of Tilletia spp. have been hampered by the lack
of genetic markers. The work discussed here is a first report of the
isolation of genetically marked strains of J. caries and their use in
wheat plant infection studies. Procedures for the isolation of auxotrophic and drug-resistant mutants in...
When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...
