The mechanisms of pool maintenance were investigated in a small (width = 10 m,
drainage area = 18 km2), gravel-bed stream where pools are commonly associated with
large, in-channel obstructions. Measurements of boundary shear stress, scour and fill of
the stream bed, and bedload transport rate and grain-size distribution were...
The plan of the present study was as follows:
1. A survey was made of professional textbooks dealing with methods of teaching science and biology. Only books published since 1920 were used.
2. Recently published high school textbooks, workbooks and laboratory manuals, and teachers' guides were reviewed for teaching aids....
During the years between 1930 and 1950 a number of attempts
were made to introduce techniques and ideas from cytology,
ecology, and genetics into the field of taxonomy. Advocates of
this "experimental taxonomy" believed that cytological, ecological,
and genetic techniques would provide a rigorous, objective
methodology to replace the traditional...
The Macrocheles glaber species group contains many
of the common mites which are associated with the dung
of domestic animals. Species in the glaber group have
been investigated for their use as biological control
agents of synanthropic flies.
Over 10,000 slide-mounted specimens of Macrocheles
in the OSU Acarology Collection and...
Traditional readings of George Bernard Shaw's texts suggest that he is not a pure
Marxist socialist because of the spiritual and nationalist aspects of his vision. This thesis
attempts to confront Shaw's politics in order to demonstrate that he indeed offers a viable
socialist program. Overlaying his socialism with Louis...
A Mixed Reactant Single Chamber (MRSC) Fuel Cell is a relatively recent concept in the field of fuel cell engineering originally developed in the late 1950’s. Typical fuel cells have separated reactants (a separated fuel and oxidizer) that react on their usually non-selective electro-catalytic materials. A mixed reactant fuel cell...

Red Light Ladies presents a perspective on prostitution in North America, within the context of the western mining frontier. A biographical profile of the frontier
prostitutor is presented, along with an archaeological model of settlement patterns and material culture. Settlement patterns and demographic changes in the prostitutor
population are hypothetically...
In February 1905 the Oregon State Academy of Sciences formed in
Portland to promote scientific research and diffusion of scientific
knowledge in Oregon. The founders also planned to assist in the
discovery and development of the state's natural resources. The
Academy was the first scientific society in Oregon with professional...
The transport response of four marine psychrophilic bacteria
to a variety of substrates was determined and related to environmental
conditions. Studies on pressure and temperature effects on glutamic
acid transport and utilization indicated that high pressures and
low temperatures inhibit glutamate transport, while permitting glutamate
respiration. Similar results were obtained...
This research assessed certain specific plant-soil and community
interrelationships in eastern Oregon habitat types dominated by
subspecies of Artemisia tridentata.
The first evaluation described plant-induced soil chemical patterns for Artemisia tridentata plant communities of high perennial
grass-low shrub and low perennial grass-high shrub composition. Soil
concentrations of total nitrogen, organic...
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,...
The thermophilic aldolase from Bacillus stearothermophilus
(NCA 2184) has been purified to a specific activity of 45.5 μ-moles
of fructose-1, 6-diphosphate cleaved per minute per mg of enzyme,
representing a 624-fold increase over the crude extract. The preparation appeared to be homogenous by sedimentation velocity ultra-centrifugation
and by a specific...
These short reports are intended to inform the public, industry, and other interested parties of the current studies of the Commission's staff and the basis for conservation measures. Reports will be published from time to time when _studies are sufficiently complete to provide reliable biological evidence for conclusions upon which...
Water potential, leaf conductance, growth, nitrogen
content, and seedling survival of Wyoming Big Sagebrush
(Artemisia tridentata ssp. wyomingensis) following
defoliation of the herbaceous understory were assessed
during two growing seasons. Precipitation was 107% and 63%
of the long-term mean (283 mm) in 1989 and 1990,
respectively, which presented an opportunity...
Habitat for wildlife species that depend on sagebrush ecosystems is of great management concern. Evaluating how management activities and climate change may affect the abundance of moderate and high-quality habitat necessitates the development of models that examine vegetation dynamics, but modeling tools for rangeland systems are limited. I developed state-and-transition...
The data included here were compiled for use in the 1980 Renewable Resources Planning Act Timber Assessment conducted by the U.S. Forest Service. They were used to develop structural equations and relationships comprising the 1980 Timber Assessment Market Model. These data series-covering U.S. demand, U.S. supply, and Canada-span 27 years...
Juniper is a native species to Oregon and confers ecological benefits to wildlife when it is at savannah and transitional densities. Its range and extent have fluctuated with climatic change, but the current range expansion is unprecedented in its extent. The range expansion has been associated with the degradation of...
"This Long Disease, My Life": Alexander Pope and the
Sciences by Marjorie Nicolson and G.S. Rousseau has been the
standard work on Alexander Pope and Newtonian science ever
since it was published in 1968. Literary scholars and
biographers continue to be swayed by its influence.
Unfortunately, the work they so...
While historiography and interest in Tudor England at both the popular and specialist levels presents few signs of diminishing, there may nonetheless exist a sense that we have little left to learn about this period and its culture. A notable gap in our knowledge, however, remains regarding the mysterious disease...
The publication of Charles Darwin’s On the Origin of Species, truly a synthesized work of natural history, coincided with the emergence of specialized disciplines in the 19th century. This thesis aims to explore the relationship between the specialization of knowledge, in the form of disciplinization, and the reception of new...
In their modern context questions of heredity have come to be
closely aligned with theories of evolution because all such theories
require the presence of heritable variation. Thus the need for an
understanding of a source of variation and a mechanism for its inheritance
became very apparent with the general...
Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...
A year-long caged study the belted kingfisher (Megaceryle
alcyon) combined time-budget and food-balance techniques to obtain
data on daily energy consumption (DEC) throughout an annual cycle.
This study tested the hypothesis that seasonal variations in DEC
could be predicted as a function of temperature, photoperiod, and
timed-activity data. The DEC...

This index covers the monthly issues from 1950 through 1976 as well as the annuals, which were dated as monthly issues but...
This is a comparative analysis of groundwater conflict and surface water conflict in Idaho from 1950-2019. The work looks at Idaho's exceptional experience with water and demonstrates that water conflict in Idaho is different than in other PNW states. The work outlines that Idaho's water conflict is almost solely focused...
Remnants of railroad logging camps, and their associated features, are perhaps some of the most common archaeological resources found on public lands in the Pacific Northwest. Many camps have already been located, their cultural materials inventoried, and networks of logging railroad grades mapped. Yet, despite these efforts, little can be...
The Oregon State University Production Line of Single
Comb White Leghorns was under selection for increased henhoused
egg production from 1947 through 1972. Since henhoused
egg production is directly related to mortality,
mortality would be expected to decrease over the years if
selection was effective. To determine if the mortality...
