Karyotype analyses have been madeon only two on the six recognized species in the genus Pseudotsuga, Douglas-fir (P. menziesii) and bigcone Douglas-fir (P. macrocarpa). In this
study, a comparison was made between the karyotypes of Douglas-fir and Formosan Douglas-fir (P. wiloniana). The basic chromosome number of the Formosan Douglas-fir was...
In this thesis I examine the ideological mechanisms that work to constitute, construct, and maintain subject identity. Such mechanisms include repetition, performativity, identification, and interpellation. I incorporate structuralist, post-structuralist, and psychoanalytic theories as a means to discuss the ways in which gender, sexuality, and identity are performative masquerades.

Mission Mill Museum Association purchased the woolen mill after its closure in order to develop the property as a museum. The purpose of this study was to provide...
A unique mass-flow control system for the carrier gas
in gas chromatography is described and evaluated. Carrier
gas flow is controlled by a flow sensor, feedback electronics,
a flow-control valve and a microcomputer. The
flow-rate is monitored by a mass-flow meter by this system
and the flow is adjusted in...
There is a considerable amount of vacant land
zoned for industrial use within the Corvallis Urban Growth
Boundary. A detailed investigation of the area reveals
a total of 632.98 acres of such land. However, when closely
scrutinized, it appears that the total number of acres is
misleading, as only 77.50...
The purpose of this study was to determine if
computer assisted instructional (CAI) tutorials in high
school biology differ in effectiveness in terms of
student academic achievement when compared with the more
traditional lecture/discussion type of instruction.
Additionally, student attitudes toward CAI were measured
using a student attitude questionnaire.
The...
The purpose of this study was to investigate an application of
statistical concepts to quality control of highway construction. The
application was presented qualitatively and demonstrated quantitatively
by an investigation of asphalt content in asphalt concrete.
For the example, an Oregon State Highway Project was
sampled and tested. The average...
