Early diagnosis is essential for proper management of the Marfan syndrome, yet due to diverse manifestations of the disorder, specific diagnosis is difficult. Excessive growth of the long bones constitutes a major characteristic of the syndrome; thus differences in growth patterns from those of the average child suggest a possible...
This study was designed to provide life history information about juvenile fall Chinook salmon, Oncorhynchus tshawytscha
(Walbaum), in a small coastal river by 1) documenting the length of residence of the juveniles throughout the river, 2) exploring several factors possibly influencing their length of residence, and 3) assessing the relative...
During the summers of 1970 and 1971 a total of 95 sea otter (Enhydra lutris) were shipped to Oregon from Amchitka Island, Alaska. The 1970 shipment consisted of 31 otter which were to be released on the southern Oregon Coast near the town of Port Orford. Two of these animals...
Line balancing is concerned with the optimal assignment of work elements to individual operators in an assembly line of a mass producing system. This paper summarizes the assembly line balancing terminology, the computational methods, and objective functions applicable to a wide variety of assembly lines. Single and mixed-model situations for...
Ecological and historical information are combined in examining the environmental influence of fire and grazing on rangelands in eastern Oregon through time. Competitive relationships between herbaceous and woody flora in the northern Great Basin are discussed, focusing broadly on the shrubsteppe regions 'of Franklin and Dyrness (1973) but with special...
An experimental formulation of 9 -oxodec-trans-2-enoic acid, the major component of honey bee (Apis mellifera L.) queen pheromone, was tested for its effect on worker foraging behavior in the pollination of sweet cherries (Prunus avium L. ). The test formulation consisted of a solid beeswax cylinder impregnated with a measured...
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...
An analysis was made of the recent catastrophic disturbance history of forests at Mount Rainier National Park. Basic data were tree ages from ring counts of increment cores taken from the early seral cohort, field mapping of age class boundaries and aerial photograph interpretation. Maps of present stand ages were...
The food consumption and growth of Pacific oyster larvae were studied in three experiments making use of a constant flow apparatus. The apparatus maintained a continuous flow of various densities of
algae through test chambers containing different numbers of larvae in a factorial design. Three additional experiments were conducted in...
This thesis is a documentation of a selected number of nineteenth century quilts studied by the investigator in the Willamette Valley.
The quilts were located in museums and in individual's homes. A questionnaire, that was developed for this study of quilts, was
filled out as each quilt was examined. Slides...
The Tlingit Button Blanket was developed on the Northwest Coast of North America in the early 19th century as a result of the introduction of foreign materials brought by European explorers and traders in the late 18th century. The-Tlingit Indians substituted trade items for indigenous materials and integrated the resulting...
This thesis is an ethnohistoric study of the water rights of the Yakima Confederated Tribes. The study considers the water rights issues of the Yakimas from the cultural viewpoint at the time of European contact to the present legal and political situation. It traces the many obstacles the Yakimas have...
The purpose of this study was to determine plant species composition, community structure, successional relationships, vegetational development and plant distributions in estuarine salt marshes on the Pacific Coast of Oregon.
Quadrat and transect samples of plant presence and cover, collected from April 1971 - June 1974, were subjected to phytosociological...
The purpose of this study was to identify some of the factors associated with student usage of the Student Health Services (SHS)
and of the Infirmary at Oregon State University. The population for the study was the freshman class entering Oregon State University in September, 1968. The original enrollment of...
The role of synthesis and degradation in controlling enzyme
concentrations was studied.
Concentrations of chloride and arginine were determined for
blood and liver at various stages of development from the embryo to
the 8 day old chicken. The chloride concentrations were used to
obtain the volume of extracellular blood in...
In 1906, applying Charles Darwin's evolutionary theories to the human race, Sir Francis Galton introduced the concept of eugenics, "the science of the improvement of the human race by better breeding." The rediscovery in 1900 of Mendel's laws of genetic inheritance and an upsurge in hereditarian thought set the stage...
The thesis area is located in north-central Oregon approximately 20 km west of the town of Mitchell. The rocks exposed in the area belong to the Clarno Formation. This study supports the informal reclassification of the Clarno to Group status, composed of an Upper and Lower Clarno Formation. An angular...
Four formations of the Cretaceous Nanaimo Group crop out on Galiano Island and on Parker and Gossip Islands, nearby. These formations are: early Campanian Geoffrey Formation which encloses a tongue of the Northumberland Formation; early Campanian to late Maestrichtian Spray Formation; and Maestrichtian Gabriola Formation. The stratigraphic succession has a...
The primary purpose of this study was to determine the work values of the emotionally disturbed adolescents and to compare these values with those indicated by adolescents
of the same age level from a regular public school. A secondary objective was to compare the work values of the age levels,...
Agriculture in the Willamette Valley, Oregon, has undergone continual change since the annual migrations of American pioneer farmers began to arrive in the early 1840's. The comparisons of data from each of the agricultural censuses of Oregon counties taken since 1850 confirms that change has been continual. The data revealed...
