Establishment of a non-native plant species in new habitats beyond their native range is associated with inherent changes in ecosystem properties. These changes may be dramatic or subdued, and consequences may be positive or negative depending on characteristics and response of the resident ecosystem. Non-native aquatic plant species in the...
Vaccinia virus is the prototypic member of the Orthopoxvirus genus. It undergoes a complex replication process where a key step in the transition from immature virion to intracellular mature virion is the cleavage of the major core protein precursors. The product of the I7L open reading frame (ORF) is a...
This thesis explores the potential applications for 3rd generation activity theory in writing studio spaces, using the Undergrad Research and Writing Studio at Oregon State University as a focal point. David R. Russell, Nedra Reynolds, and Deborah Brandt have all investigated systemic and communal elements in student writing processes, while...
A post-failure investigation of a highway embankment constructed
over organic and sensitive subsoils was made with a series
of field vane tests. The results indicated that the embankment was
quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...
The objective of this study was to investigate the low seed
germination of 12 varieties of Oregon grown monogerm sugar beet,
Beta vulgaris L., using several methods to determine the germination
potential. The methods were: (1) X-ray radiograph examination,
(2) standard laboratory germination following official rules,
(3) laboratory germination by...
The merits of the photoelastic coating technique as applied to
wood were evaluated. Comparative tests were made on 12 nominal
two-by-four Douglas Fir boards. The object of these tests was to
determine the limitations of this technique, such as accuracy and
complexity of experimental procedure. Correlation of the experimental
results...
Samples of Douglas-fir chips and western hemlock/true fir chips were pulped by the kraft and sulfite processes respectively. The spent liquors were analyzed for fluorescent response, and the fluorescent intensities of each liquor sample correlated with yields, Kappa numbers, and lignin contents of the pulps. Linear relationships were seen between...
This study is a synthesis of the available ethnographic and relevant archaeological data pertaining to the Native American groups who formerly occupied the upper Rogue River drainage of southwestern Oregon. The information presented in this synthesis concerns the material, social and religious aspects of aboriginal life as practiced by the...
Dietary fiber has been suggested as interfering with
mineral utilization. The influence of broccoli florets and
wastes, cauliflower heads and wastes, wheat bran and Metamucil
on mineral uptake by the rat was determined using
balance studies. All results were compared to control
animals fed diets containing 10% hydrolyzed cellulose.
Utilization...
