In 1746, Dr John Buchanan, a recently retired medical officer in the British Army, produced a manuscript, 'Regimental Practice, or a Short History of Diseases common to His Majesties own Royal Regiment of Horse Guards when abroad (Commonly called the Blews).' Revised almost until the time of Buchanan's death in...
Monophyly of the gomphoid-phalloid clade was confirmed based on multigene
phylogenetic analyses. Four major subclades (Hysterangiales, Geastrales, Gomphales
and Phallales) were also demonstrated to be monophyletic. The interrelationships
among the subclades were, however, not resolved, and alternative topologies could not
be rejected statistically. Nonetheless, most analyses showed that the Hysterangiales...
This study was directed to improve our understanding of the ecology of Swiss needle
cast (SNC) of Douglas-fir, a disease that produces extensive damage to forests and
plantation in the coastal region of Oregon and Washington. A disease prediction model
for the coastal area of Oregon was built by establishing...
The Coast Reservation of Oregon was established under Executive Order of
President Franklin Pierce in November, 1855, as a homeland for the southern Oregon
tribes. It was an immense, isolated wilderness, parts of which had burned earlier in the
century. There were some prairies where farming was possible, but because...
Accurate taxonomy is essential to preservation and management of native
grasses. Four problems in fescue taxonomy were investigated: the identity of the
native fescue that dominates western Oregon and Washington prairies, the relationship
of native Festuca roemeri to closely related grasses, the status of F. howellii and F.
washingtonica, and...
Arsenic concentrations exceeding the U.S. Environmental Protection Agency (USEPA) current Maximum Contaminant Level (MCL) of 50 micrograms per liter are widespread in ground water in the Willamette Basin. The Oregon Water Resources Department and the U.S. Geological Survey began a cooperative study in the Willamette Basin in 1996. One goal...
Chipping varieties and model systems were used to determine the role of potato
constituents on chip color. Composition was evaluated by HPLC and chip color
measured using a ColorQuest colorimeter. Reducing sugar (RS) content did not
completely explain color quality when present in low concentrations (<60 mg/lOOg).
Levels of ascorbic...
The effects of late spring defoliation on the winter forage quality of bluebunch wheatgrass
(Agropyron spicatum [Pursh] Scribn. & Smith), Idaho fescue (Festuca idahoensis Elmer) and elk sedge
(Carex geyeri Boott) and the response of wintering Rocky Mountain elk (Cervus elaphus nelsoni Bailey) to
changes in winter range forage quality...
Women entrepreneurs are an economic force within the American and Oregon economy. Women are starting businesses at two to five times the rate of men. There has been significant research detailing the demographics, barriers, and business management skills of women business owners. Yet, the research to date has been limited...
During the summer and fall of 1982, personnel from the Geophysics
Group in the School of Oceanography at Oregon State University conducted
an aeromagnetic survey in the northern Oregon Cascades to
assess geothermal potential and study the thermal evolution of the
Cascade volcanic arc.
Total field and low-pass filtered magnetic...
Food habits and levels of organochlorine compounds, lead, and mercury in resident and wintering bald eagles were studied in southcentral Oregon and California, 1979-83. Food habits were assessed by examination of castings from winter communal roosts, identification of 2938 prey items found at nest sites and foraging areas, and observations...
The 109-year-old Porter house in Shedd, Oregon is one of few
remaining, well-preserved examples of Rural Gothic architecture in the
Willamette Valley. This study attempts to record its history: the
economic circumstances which led the pioneering David Putnam Porter
family to build this relatively large house, the family background,
and...
Shear wave attenuation measurements were made
using ceramic bimorph transducers to excite transverse
vibrations in a cylindrical column of unconsolidated
sediment. Three different water-saturated
sediments were used in an attempt to determine the
effects of grain shape and sorting on the frequency
dependence of attenuation. The mean grain size of...
A thermodynamic analysis of forced geoheat recovery from aquifers
has been accomplished. The system investigated consists of a single
recharging-discharging well pair, in a horizontally extensive aquifer,
with either power generation or space heating as surface applications.
The space heating systems investigated are (i)direct heating, (ii)heat
pumps and (iii)a combination...
Infiltration, soil erosion, nitrogen loss and soil profile
characteristics were measured on 36 sites representing land occupied
by Artemisia tridentata ssp. tridentate, wyomingensis, and vaseyana.
Infiltration, soil erosion, and nitrogen loss were strongly correlated
but highly variable. Soil loss, but not infiltration or nitrogen
loss was significantly different between subspecies....
Fifty species and subspecies and six varieties in eight genera of
the family Tabanidae are recognized from Oregon. The following genera
are represented in Oregon: Apatolestes Williston, Pilimas Brennan,
Stonemyia Brennan, Silvius Meigen, Chrysops Meigen, Atylotus Osten
Sacken, Hybomitra Enderlein and Tabanus Linnaeus. Adults and larvae
were collected from various...
The genus Lichnanthe Burmeister contains eight extant and one
fossil species which are strictly nearctic in distribution. The
subfamily Glaphyrinae, however, is distributed nearly world-wide.
Five species were previously described and three are described as
new herein. All eight extant species are described in detail herein,
synonomies are made current,...
Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One-hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least...
This thesis is concerned with the analysis of heat transfer in a tube with forced flow under conditions of an arbitrary variation of wall heat flux both axially and circumferentially. This total study is separated into two distinct problems which are presented separately. The first is the case of a...
The purpose of this study was to explore the effectiveness of
Title III of the Elementary and Secondary Education Act in selected
schools of the Oregon Small Schools Project. Specifically, the
objectives were to analyze:
1. To what extent were the objectives of the OSSP
accomplished.
2. To what degree...
While the public trust doctrine at common law placed effective limitations on the Crown, these limitations have been somewhat obscured by state court decisions in the United States. Though some courts have suggested that the public trust places limitations or the power of the legislature to convey lands beneath navigable...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
Seventy-two species of Blennocampinae in 21 genera and six tribes
are known from the Nearctic region. The adults and known larvae of
all species and genera are keyed, described and illistrated. A
definition of the subfamily, a review of previous work, a table of
host-plant associations, and a discussion of...
This paper discussed the human electrocardiogram, the instrumentation
used to graphically record it, and the design and performance
of a specialized system for vector cardiography: the Vector Electrocardioscope
(VECS) System. The introduction reviews in considerable
detail the pertinent known physiology of the heart, especially the
electrophysiology responsible for the genesis...
