The analysis of prehistoric stone features has suffered for two separate but related reasons. The first is the lack of stringency in defining the terms attributed to these structures and, second, the perception of a lack of formal attributes exhibited by them. These two factors have made it impossible to...
From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...
An important factor affecting the strength and ultimate load of wood structures is the strength, stiffness and durability of its joints. Therefore, the behavior of nailed joints must be given proper consideration when designing and analyzing wood structures. Presently,formulas for determining the strength of nailed joints under withdrawal loads, as...
Regression equations applicable to biomass components of standsof western hemlock [Tsuga heterophylla (Raf.) Sarg.} were developedby destructive sampling of a thinned and an unthinned stand ofwestern hemlock near Seaside, Oregon. Equations predicted more live-branchbiomass and less dead-branch biomass per tree for the thinnedstand, but equations for biomass of foliage, twigs,...
The Middle and West Forks of Little Sheep Creek in the southern Tendoy Range have incised valleys across Cenozoic structural features exposing strata that range in age from the Mississippian to the Neoene. Paleozoic strata are 1,349 m thick and belong to the Mission Canyon Limestone, the Big Snowy, Amsden,...
This thesis is an effort to formalize and document some of the changes occuring in the Warwar Valley of Gongola State, Nigeria, West Africa. The documentation will comprise a photographic study over time accompanied by an ethnographic narrative. Information gathered from photographic images, field notes and the anthropological record will...
Subsurface mapping was used to determine the structure andgeologic history of the South Cuyama dome and part of the Russellfault in the South Cuyama oil field area. Deformed Late Cretaceousand or early Tertiary marine strata are unconformably overlain bythe late Oligocene to early Miocene Vaqueros Formation (QuailCanyon Sandstone Member, Soda...
The Santa Barbara-Montecito and Goleta basins are structurally
continuous fault-controlled Pleistocene basins containing
up to 3000 feet (925 m) of marine Pleistocene Santa Barbara Formation
which were deposited on previously deformed Sisquoc and older
strata. Structures subcropping against the unconformity at the
base of the Santa Barbara Formation show that...
The Grants Pass Batholith of Cretaceous age has intruded the
Triassic Applegate Group and metasedimentary rocks of the Jurassic
Galice Formation in the Murphy area of Josephine County, southwest
Oregon. The Applegate Group, mafic volcanic and sedimentary rock,
has been partially (nonequilibrium) metamorphosed under greenschist
facies conditions. The batholith, a...
Initial sites of localization and multiplication of Pasteurellamultocida were examined in chickens intravenously inoculated with varying doses of bacteria. Sections of lung, liver, kidney, bone marrow and spleen were prepared for light microscopic examination.Tissue sections were stained with the hematoxylin and eosin stain,Gram's stain or the avidin-biotin-peroxidase complex immunoenzymatictechnique. Of...
The purpose of this study was to examine the relativeeffectiveness of functional isometric squats on thedevelopment of dynamic strength, static strength and powerof college males. Ten college males volunteered for thestudy. The subjects trained two days per week for a totalof eight weeks which consisted of a two week preconditioningperiod...
The Ataspaca prospect is in the Cordillera Occidental, 45 km northwest of Tacna, Peru. Epizonal intrusions satellitic to the Caplina- Ataspaca pluton were emplaced 41 m.y. ago into limestones of the Lower Jurassic Pelado Formation along the northeast-trending Chucchuco fault system. Depths of emplacement ranged from 4.5 to 6.0 km....
Approximately 23 square miles of the east-central part
of the Tendoy Range are included in the thesis area which
lies three miles west of Dell, Montana.
Rocks ranging in age from Late Mississippian to Recent
are exposed in the study area. The upper Paleozoic section
includes approximately 4,200 feet (1,281...
Since the early 1950's, the distribution of sediment at the
mouth of Redwood Creek has been altered by the effects of channel
aggradation and channelization along the lower reach. Severe flooding
in 1953, 1955, and 1964 caused bank erosion, landsliding, and
channel geometry changes along Redwood Creek. The increased sediment...
Concern regarding the lack of genetic variability and the apparent yield plateau reached in wheat breeding have prompted this investigation. The systematic crossing of spring and winter wheat types which have evolved to form somewhat different gene pools, may provide a source of additional usable genetic variability for future yield...
Spring grazing of annual ryegrass (Lolium multiflorum L.) seed
fields with sheep is a common practice in the Willamette Valley of
Oregon. However, the effect of grazing on seed yield in Oregon has
not previously been investigated. This experiment was designed to
determine the effects of duration of spring grazing...
The primary cause of "early dying" disease of potatoes in
Oregon is Verticillium dahliae; however, Colletotrichum atramentarium,
Erwinia carotovora subsp. carotovora (Ecc) and E. carotovora
subsp. atroseptica (Eca) are also commonly isolated from
diseased plants. Therefore, field and greenhouse studies were
initiated to determine the relative involvement of each pathogen,...
Samples of commercial purity titanium were heat treated above the
beta transformation temperature and within the two phase alpha-beta
phase field, followed by cooling at varying rates. Testing of the
samples in tension and by instrumented impact indicated that some
strengthening could be imparted by these heat treatments, although at...
In 1968, a study conducted by the sanitarians of the State Health Division and Benton County Health Department revealed a high failure rate of on-site sewage disposal systems in Southwest Corvallis. The survey team concluded that sewage disposal in this area was inadequate, and a significant health hazard existed due...
Previous work indicated a substantial heterotic expression for grain yield existed within winter/spring hybrids of barley, This research was a continuation for the comparison of the expression of heterosis within winter/spring hybrids to the heterotic effect produced among the winter and among the spring parents. The F₁ and F₂ progenies...
Most measures of program complexity gauge either textual or
control flow attributes of a program. A recent addition to the field
of complexity measures, the knot metric, is a function of both these
attributes. A knot measurement reflects the degree of control-flow
tangle in a program's listing. This thesis discusses...
An experimental investigation has been performed to determine the
forced convection heat transfer due to three-dimensional air flow over
a flat plate as a function of angle of attack and free stream velocity.
The experimental method employed a transient thermal technique and
placed the convecting surface next to the exhaust...
A rapid virus detection method was developed for Infectious Hemotopoietic Necrosis Virus (IHNV). The virus detection method could be applied to Infectious Pancreatic Necrosis Virus (IPNV) under certain conditions. It was possible to detect IHNV to a lower limit of 1.7 X 10⁴ Tissue Culture Infectious Dose for 50% (TCID₅₀)...
Implementation of. the Fishery Conservation and Management Act of
1976 affords opportunities for fishery expansion and economic development
in the Oregon otter trawl fishery. The changes stimulated by the
Act should occur, according to social science theorists, by the
diffusion of innovations from innovative fishermen to less innovative
fishermen, with...
This thesis examines one aspect of social change in Nepal. Contact
with the outside world since 1951 has provided a non-traditional
means of achieving access to highly valued occupations, resulting in
the formation of an emerging elite. High caste status is no longer
absolutely necessary to gain access to education,...
The Philpott site (35CS1) is located on the north bank of the
Coquille River near Bandon, Oregon. Test excavations at the site were
conducted in 1978 by Oregon State University under the direction of
Richard E. Ross.
One artifact assemblage and one distinct component were defined
during the analysis of...
Dyphylline is an analog of theophylline and the latter
is the most popular member of the methylxanthine family in
use for the treatment of asthma. Although dyphylline is
devoid of some problems associated with theophylline, a
reported short half-life has made it's clinical usefulness
limited. To avoid this problem a...
The awareness of sex-trait stereotypes among 120, eight-year-old children from intact families in both rural and urban areas in Korea were investigated. The rural sample included 20 boys and 20 girls attending the Damyang-Dong Primary School in Damyang-Eup, Korea. These subjects came primarily from farm families of the upper-lower and...
Purebred Yorkshire gilts from a confinement managed herd were reared to test weights away from the sow and boar herd. Thirty-eight gilts weighing between 73 and 80 kilograms constituted group A gilts; 38 gilts weighing between 91 and 100 kilograms constituted group B gilts; and 47 gilts weighing 114 kilograms...
