Fire blight is a serious disease of apple and pear trees caused by the bacterium, Erwinia amylovora. This bacterium harbors a pathogenesis mechanism known as the Hrp secretory operon which induces some resistance genes and suppresses other resistance genes in the host plant following invasion. While previous researchers analyzed expression...
Solute transport models in karst groundwater must consider variable and complex flow regimes. Within fissures less than 2 mm in aperture, during unsaturated flow events, seeping flow may flow as films or under capillary tension as a capillary rivulet. This project focuses on exploring the mass transport characteristics of seeping...
Google Earth has given internet users the power of a virtual globe at their fingertips. It is
a free, easy to use tool that avoids the need for technical training, and uses a simple,
intuitive interface. For this reason, Google Earth appeals to general and more specialized
users. This project...

My thesis examines a total of fourteen characters from The Portrait of a Lady and The Turn of the Screw. Primarily, I have discovered an overwhelming pattern in these two works by Henry James; when characters make direct entrances--that is when they are not described or discussed in absentia by...
Data in the form of counts or proportions often exhibit more
variability than that predicted by a Poisson or binomial
distribution. Many different models have been proposed to account
for extra-Poisson or extra-binomial variation. A simple model
includes a single heterogeneity factor (dispersion parameter) in the
variance. Other models that...
This study was initiated to characterize the distribution of Fe-Mn nodules and to elucidate trends of Fe, Mn, and P relative to the intensity of the annual cycles of reduction and oxidation. Nodules were enriched in Fe, Mn, and P relative to the soil matrix making them an integral part...
This research addresses the functional characteristics of a single
organization. It specifically investigates one of the largest festival
organizations in the United States, The Portland Rose Festival Association
(PRFA). In this case, three groups within the PRFA are its foundation: the
paid staff, the executive committee, and the volunteer directors....
The purpose of this study was to assess the congruence of perceptions of academic advising between students and advisers. Seventeen tasks involved in developmental academic advising were identified from a review of current academic advising literature. These criteria became the basis of a questionnaire that asked students whether their adviser...
Because forage quality of cool season grasses declines to sub-maintenance levels for ruminants late in the growing season in the northern Great Basin, there is a need to elevate protein levels and digestibility of grasses for both wild and domestic ruminants in late summer. Anderson and Scherzinger (1975) proposed using...
