Rethinking the Dualism: Don DeLillo's White Noise and the Ecocritical Possibilities of the Nature/Culture Mix questions current applications of ecocriticism and offers that these applications are inadequate in dealing with the perceived nature/culture dualism. This thesis suggests that ecocritics need to stop thinking in dualistic terms, but instead must consider...
This thesis seeks to explain how Lord George Gordon
Byron achieves catharsis through the writing of his truth
in Don Juan. In the poem the narrator expresses Byron's
innermost emotion while at the same time the protagonist,
Juan, relates to readers on a more conscious level. The
ability that Byron...

Reforestation of certain areas of southwestern Oregon has become a serious problem. Reforestation failures are evident in numerous clear-cut stands, but failures are also noted in various partially-cut stands. The Dead Indian Plateau, approximately twenty miles east of Ashland, Oregon, has many areas where this is evident. This study investigated...
In view of the stimulant effects of gibberellic acid on plant
growth, and its interesting modifications of various metabolic products,
it was decided to determine whether this growth regulator
would induce a favorable effect on total alkaloid production, especially
on the antineoplastic alkaloids, of Catharanthus roseus (L.) G. Don
(Vinca...
Low levels of copper have been shown to impair the olfactory system of threatened and
endangered (T&E) salmon, decreasing their predator avoidance behavior and likely
increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion
(Cu2+) and weakly complexed species are truly bioavailable. Previous studies indicate the
vast...
I experimentally test the hypothesis that the potential for selfing
increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible,
profusely-flowering perennial. This follows from the
premises that 1) pollen dispersal by pollinators between flowers is
limited, and 2) individual pollinators, in this study bumblebees, will
visit more flowers per...
In conventional cropping systems in the Willamette Valley, slow
establishing grass species, such as Kentucky bluegrass (Poapratensis L.) are planted in the spring and seed is not harvested
until the following year. Due to increasing annual production
costs, it is necessary to generate a cash return from each field
each...
This research addresses sample process variance estimation on continuous domains and for non-probability samples in particular. The motivation for the research is a scenario in which a program has collected non-probability samples for which there is interest in characterizing how much an extrapolation to the domain would vary given similarly...
One of the major items in any program of municipal sanitation is the double problem of water supply and waste water disposal. Since streams are the general source of water supply and also the final receptacle for sewage, this dual use of the stream often leads to complications. Sewage and...
This project performs a style analysis of three sentences from three military manuals written across an 80 year time-period.

was used as the indicator organism. The plant was operated under
a variety of conditions in...
Subterranean clover (Trifolium subterraneum L.) seed production
practices in Oregon are different from those in Australia.
There, seed is produced on fields which are managed primarily for
forage. In Oregon, seed fields are managed for seed as the primary
product and forage is of secondary concern.
Some sheep grazing is...
The objective of this study was to develop a soaking and drying
procedure to stimulate faster germination of Kentucky bluegrass (Poa
pratensis L.) seed.

to overcome this temperature-related dormancy problem so
that better stand establishment could be realized from
early fall planting....
There is an increasing need for development of laboratory
identification procedures for purposes of plant variety protection, seed certification, quality control and consumer protection. In the past there were fewer commercial varieties and field
testing methods based on morphological differences were used satisfactorily. These tests require several months to complete...
The use of crownvetch (Coronilla varia L.) as a forage crop
might be increased considerably if seed with low hard seed content
could be made available at reasonable cost. Since mechanical scarification
damages a large percentage of crownvetch seeds, this study
was initiated to find other ways of reducing hardseededness....
Three deep experimental filters were used to evaluate the influence
of the physical factors of media size, depth of filter, and organic and hydraulic loading on contact time and the rate of removal
