The Washougal Mining District is located on the western flanks of the southern Cascade Range of Washington, approximately 50 km (30 miles) northeast of Vancouver, Washington. The district has produced only $573 since 1903, derived from copper and silver. The presence of hydrothermal mineralization and breccia pipes similar to those...

This study examines in detail a continuous drop-size distribution
recorder and selected data gathered with this recorder at
various locations on 6, 15, and 31 May 1966. The drop-size distribution
recorder consists of a self-contained, mobile unit able to
operate without electric power. This recorder utilizes "Ozalid 105
SZ" filter...
This paper describes the analysis of data from a three-year gross time study of skyline, balloon, and helicopter yarding systems operating in Western Oregon. Data collection activities were designed and supervised by the Pacific Northwest Forest and Range Experiment Station, U.S.D.A. Forest Service. The specific logging systems studied were running...

This paper describes a computer program developed for the Hewlett
Packard 9830, which analyzes and computes costs and engineering
data for paper plan timber harvest road networks. The program will
accept up to 110 road segments. Each segment is analyzed individually
based on digitized data from a contour map and...
A brief history of X-ray control methods is presented, and
the instrumentation requirements and physiological considerations
pertaining to an automatic X-ray control system are discussed.
The latter half of the thesis describes the design and operation
of a device which will permit medical radiographs to be taken
automatically and at...
It is well known that every Banach space with a Schauder basis
is separable. However, whether the converse of the above statement
is true is not known.
It is therefore the purpose of this thesis to investigate the question
of under what conditions an arbitrary, separable, Banach space
has a...
This study, dealing with the concept of career education, was
undertaken to:
1) develop a multi-media career education component for Phase I
of the undergraduate teacher education program at Oregon State
University.
2) measure the effect of that component on selected students.
3) compare their responses with students who had...
In October 1977, a study was undertaken to determine the role of bovine adenovirus type 3 in enzootic pneumonia of calves, and the efficacy of using a vaccine for prevention of disease. Bovine adenovirus type 3 was isolated from the herd under study in the previous year. Calves in the...
The purpose of this research study was to create an
integrated systems framework to analyze the planning
process in family businesses. The model was developed
from a literature review of family study, organizational
development, and family business research. Major
components of the family business planning process were
identified. A systems...
The thesis describes the properties of surface wind and air
temperature time series recorded at three locations on the pack ice
of the Beaufort Sea. Time series consisting of sequential one-half
hourly means were constructed for a period of approximately a year.
A diurnal fluctuation in air temperature is found...
Many species of rodents and insectivores live in subterranean burrows in soils throughout the world. The soil surface perforations of burrow entrances are often connected to complex, subsurface tunnel networks. Burrow entrances and associated subsurface tunnel networks represent a link between surface and subsurface ecological function. Anecdotal observations of surface-water...
