Voter preference on the issue of comprehensive land use
planning in Oregon was analyzed through various population
characteristics in order to determine the factors
contributing to public preference in this issue and how they
were distributed spatially. Two statistical models were
developed to analyze the correlations between voting outcome
in...
This thesis investigated the methods of failure in the webs of
built up girders. The beams had rectangular holes five and one-half
inches wide and seven and one-half inches high with rounded corners
in a web fourteen inches deep between flanges. The longitudinal
position of the hole edge varied from...
The past decade of research has potentiated a revolution in our understanding of mammalian health and evolution by revealing that the gut microbiome plays a central role in mammalian physiology. Our ability to unlock this potential hinges upon the identification of specific groups of gut microbes that elicit effects on...
This dissertation is concerned with the diminution of Oregon's Umatilla Indian Reservation over a 120 year period (1855-1975). Its objective is to show that the transfer of land from Indian to non-Indian ownership was most attributable to four casual factors:
(1) historical happenstance, including the passage of the Oregon Trail...
The developmental patterns of five fuel resources located within
the state of Wyoming are examined through time and in relation to
several factors external to the location of the fuels. An historic
description and inventory of the five fuels: petroleum; natural gas;
oil shale; coal; uranium are presented. External factors...
Though inconsistent with many economic
standards for resource policy, the Mining Act of
1872 is still a valid management priority on
federal lands throughout the western U.S. When
the Law was enacted, its stated objective was to
promote private development of federally held
minerals. However, the Act's free access
provisions,...
Benzo[a]pyrene (B[a]P) is a common environmental pollutant produced from the incomplete combustion of organic matter, such as fossil fuel emissions. In vertebrates, B[a]P exposure is associated with hyperactivity, though the underlying mechanisms driving this effect are undescribed. Mounting evidence indicates that the gut microbiome, which is the diverse community of...
This study investigated the private costs to individual households
of large-lot zoning policies. The study asked whether typical
zoning ordinances create shortages of small lots or small structures
and, if so, what the magnitude of the resultant welfare loss is.
The hypotheses were suggested by a theoretical model developed
to...
The Minerals Yearbook and the Census
of Minerals Industries' statistics lack detail,
completeness, and accuracy concerning stone and
sand and gravel in Oregon and are therefore
deficient in their utility. The lack of detail and
completeness causes extreme difficulty in comparing
varied field-checked statistics. The inaccuracy
of the data concerning...
Experimental infection of mice with Candida albicans leads
to significant suppression of cell mediated immune responses.
We have characterized the nature of this candida-induced
suppression with formalin killed Candida albicans (FKCA) in the
yeast and mycelia' phase. Mice (BALB/c or C57B1/6J) treated
with FKCA exhibited a reduction in the T-cell...
