A need exists to develop a high speed dynamic tow carriage used to
motivate hydrodynamic specimens through a fluid environment. It is
desired to simulate high Reynolds number unsteady flow about the
specimen by towing the specimen through the fluid. The fluid
environment is to be provided by the existing...
This report summarizes the results of a field study of a population
of the Pacific mountain beaver, Aplodontia rufa pacifica, from
August 1965 through August 1967. The study site consisted of a 13. 5-
acre grid on a logged over area in the Coast Range Mountains of
Benton County, Oregon....
A need exists to develop a non-destructive testing technique that can identify
the formation and propagation of diagonal tension cracks in conventionally
steel reinforced concrete deck girder (RCDG) highway bridges in the State of
Oregon. Such a technique could be included into a structural health
monitoring (SHM) system installed on...
The central purpose of this study was to examine physicians' knowledge of and attitudes toward hearing aids. This study was conducted with 71 general practitioners affiliated with Scarborough General Hospital in Scarborough, Ontario, Canada.
Attitude was measured by a 5-point Likert-type scale developed for the study. Knowledge was measured through...
Real ear measurements are being used to predict
and validate hearing aid fittings. The purpose of
this study was to investigate the relationship between
the hearing aid response as measured by real ear
measurements to pure tone hearing thresholds and ear
canal resonance. In order to test this hypothesis
clinically,...
Tinnitus is usually accompanied by a hearing loss; however, many
patients with tinnitus present with normal hearing. The hypothesis
was proposed that individuals with tinnitus who do not have an accompanying
peripheral hearing loss, have tinnitus as a result of a disorder
in the Central Auditory Nervous System. In order...
Noise induced hearing loss is a subject of growing
concern. Over the past 15 years, several well-documented
studies have been completed which express the relationships
between industrial noise exposure and damage to normal and
pathological ears. This research has provided knowledge of
considerable importance to developing successful hearing
conservation programs....
Fossil foraminifers from the Coaledo and Bastendorff Formations
near Coos Bay in southwestern Oregon were studied in an attempt
to determine the age and environment of deposition. Fresh unweathered
samples were collected from sea cliffs between Cape
Arago and Charleston, Oregon.
A large late Eocene delta is preserved in the...

AN ABSTRACT OF THE THESIS OF
GUY HARLAN ROOTH for the
(Name
The object of this study was to analyze the application of linear
programming techniques to ration formulation for feedlot lambs and
steers.
Three rations for feeder lambs were designed to study the application of linear programming techniques under varying ration constraints.
Rations studied were as follows:
iso-caloric rations with
three...
