Relationships between soil-water stress and plant-moisture
stress were studied with respect to soil classification and cambial
activity in Douglas-fir.
The study sites were forested with Douglas-fir and located in
McDonald Forest and near Marys Peak in the Oregon Coast Range.
Soil-water depletion was followed by the use of gypsum blocks...
In comparison with solar radiation, the energy of geothermal
heat flowing through the sea bottom is extremely small; nevertheless,
this energy is not insignificant in the circulation of the bottom water.
Calculations indicate that in the deep basins of the South Atlantic the
water volume transport necessary to remove this...
The dissertation examines the effect of two separate yet significant individual level factors—physical and cognitive traits—on entrepreneurial outcomes. The physical factor on which the dissertation focuses is the entrepreneur’s vocal cues and the cognitive traits that the dissertation investigates are the entrepreneur’s goal orientation and his/her ability to take perspectives....
Site ORYA3, the Smith House, is located in Dayton, Oregon. The archaeological project originated because owners of this structure, listed on the National Register of Historic Places, applied for a demolition permit. The 1859 home, first occupied by two early Oregon pioneers, Andrew and Sarah Smith, was considered architecturally significant,...
Achlys triphylla, a member of a medicinally active family
containing alkaloids, was examined phytochemically to determine its
possible value as a source of medicinal agents.
Pharmacological testing of the crude ethanol extract exhibited
a competitive inhibition of acetylcholine and histamine. Purification
of alkaloid 'A' from the crude ethanol extract and...
Freshwater systems cycle carbon along a spatial and temporal biogeochemical continuum, across which ecosystem processes contribute to transformations of organic matter (OM). Various ecological constraints impact rates OM transformation and production and consumption of the energetic end of respiration, methane. Microbiological processing and complete reduction of carbon substrates to methane...
This study was concerned with identifying the program activities
and resources believed necessary to support a districtwide, comprehensive
school health instruction program and investigated the perceptions
of an expert committee composed of persons involved in
school health instruction in the State of Washington.
A questionnaire, developed after extensive review of...
This study was concerned with the effect of additional time in
health instruction for 9th graders at the junior high school level.
A 120-item questionnaire, developed after extensive review of related
tests, was mailed to a jury of ten health subject matter experts.
The evaluations of all the items made...
Transition metal oxides are an important class of materials for the wide variety optical, electrical, dielectric, magnetic, and thermal properties observed. Their unique structure-property relationships allow for property tuning and often provide insight into the fundamentals of chemistry. The work in this thesis was focused on the design, synthesis and...
The lack of availability of a single, complete paper on the
analysis of a digital data acquisition system for in situ oceanographic
measurements brought about the present work. In order to compile
an accurate technical paper on such a complex system, it was necessary
to design, construct, and calibrate a...
