This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
The arts and festivals of art have today become a vital economic
force in some areas of the country and a way of life for some people.
The number and sizes of festivals, as well as audience size, has
grown tremendously both nationally and in Oregon, since 1950. Even

The paleomagnetic history of the volcanic rocks of Easter
Island was investigated using standard paleomagnetic techniques.
The remanent magnetization of 673 specimens from the three volcanic
episodes recognized on the island were measured using a spinner
magnetometer. Inclinations, declinations and virtual geomagnetic
poles were calculated for each flow. The majority...
Limnology is undergoing a transition to high-throughput -omic analysis of freshwater
bacterial communities. An important first step in making the transition is to
characterize several genomes that can be used as references to guide metagenome
assembly and analysis. Here I characterize four new freshwater cyanobacterial
genomes, a pair of lake...
Modern agricultural erosion was studied using ¹³⁷Cs from
fallout as an indicator of erosion/deposition. The study area was a
285 ha agricultural watershed in the hilly western margin of the
Willamette Valley, a high winter rainfall zone in which fall-planted
crops are commonly grown.
Objectives of the study were (i)...
Six plant pathogenic isolates of Pseudomonas
syringae pv. glycinea, the causal agent of bacterial
blight of Glycine max (L.) Merrill, and one isolate of
P. syringae pv. phaseolicola, the causal agent of halo

The estuarine-dependent brown shrimp, Farfantepenaeus aztecus, is a significant commercial fishery and important species in the Gulf of Mexico (GOM) ecosystem as well as being a key component in energy transfer between benthic and pelagic food web systems. Because of the economical and ecological importance of brown shrimp, we developed...

The Devonian Simonson and Guilmette Formations provide examples of
Cordilleran miogeosynclinal inner and middle shelf carbonate deposition
that act in response to changes in eustasy, sedimentation, and
tectonics. The Simonson Dolomite consists of four members that
collectively record three distinct transgressive-regressive cycles.

Information on current forest condition is essential to assess and characterize resources and to support resource management and policy decisions. The 1998 Farm Bill mandates the US Forest Service to conduct annual inventories to provide annual updates of each state's forest. In annual inventories, the sample size of I year...
The significance of geology is commonly overlooked by the general public and underrepresented in free-choice learning environments including national parks that exhibit spectacular examples of geological features and processes. Parks are a major contributor to public learning, and a key way to teach how geology influences many aspects of our...
A sophisticated computer program is developed to analyze flow linear
dichroism data on nucleic acids for individual base inclinations. Measured
absorption and linear dichroism data for synthetic AT and GC polymers and
natural DNAs are analyzed. The reliability of the program is tested on data for
the synthetic polymers, and...
Results of recent studies on Piagetian cognitive development,
though equivocal, showed that the architectonic of formal operational
schemata is not possessed by a sizeable percentage (up to 52%) of adolescents
and young adults. The purpose of the present study is two

This research work investigates the use of production
systems as a model of parallel processing. The purpose of
the model is to provide a suitable medium within which parallel
processing systems can be systematically specified,
analyzed, and designed. Furthermore, the model provides a
suitable means for deriving implementations of synchronization...
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...

Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....
The electron, gamma and neutron radiation degradation of III-V semiconductors
and heterojunction bipolar transistors (HBTs) is investigated in this thesis.
Particular attention is paid to InP and InGaAs materials and InP/InGaAs
abrupt single HBTs (SHBTs). Complete process sequences for fabrication of
InP/InGaAs HBTs are developed and subsequently employed to produce...

This thesis examines the food insecurity experiences of student clients of the Oregon State University Emergency Food Pantry. Utilizing semi‐structured interviews and participant observation at the food pantry, this study investigated who is using the food pantry, the forms of food insecurity they experience, how they cope with it, and...
Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...
M. E. Hard defines a mushroom as "a cellular,
flowerless plant, nourished by the mycelium which permeates
the soil or other substances on which the mushroom
grows".
In all probability mushrooms are the most, interesting of all the higher organized fungi. Within the past few years, interest in them has...
Toxin production by cyanobacterial harmful algal blooms (cyanoHABs) in freshwater systems has lasting ecological and human impacts. Nutrients, light availability, hydrology, and microbial community composition impact the frequency and intensity of toxic cyanoHABs. Climate change will exacerbate toxic cyanoHABs, making real time and predictive monitoring a vital tool for managing...
Tribal water rights and instream flows for species listed under the Endangered Species Act (ESA) have been a source of tensions in the western United States, particularly when tribes have undetermined water rights to support tribal fisheries listed under the ESA. Understanding the mechanics of past tribal settlements and their...
Avian encephalomyelitis virus-infected chick embryo homogenate
was precipitated with polyethyleneglycol 6000 (PEG), extracted
with fluorocarbon, concentrated by ultrafiltration, and purified by
isopycnic gradient centrifugation. The physical and chemical properties
of the purified virus were studied. The examination of purified
avian encephalomyelitis virus (AEV) with electron microscopy using
negative stain revealed...
The significance of dress in a first encounter situation has
been demonstrated empirically: clothing serves as a vehicle for communicating
information from one person to another. Thus, it is influential
in affecting the formation of first impressions. This

Some perennial grass seed crops such as red fescue (Festuca rubra

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...
The purpose of this report is to provide the IDB with the available information on the current status of aquaculture in most of its South American member countries.
Extensive volcanic fields on the western Arabian Plate have erupted intermittently over the last 30 Ma following emplacement of the Afar flood basalts in Ethiopia. In an effort to better understand the origin of this volcanism in western Saudi Arabia, we analyzed ³He/⁴He, and He, CO₂ and trace element concentrations...
We investigate in this thesis, the problem of stability
of thermo-viscoelastic fluid flow between rotating
