Cultivars of several cereal crops have been developed with acetohydroxyacid synthase (AHAS)
insensitivity to imidazolinone herbicides and are now an important tool for weed management.
Options for screening for imidazolinone resistant lines include direct herbicide application,
biochemical assays for AHAS activity and DNA-based methods. Herbicide and biochemical
assays for AHAS...
Vietnam is considered one of the most climate change-vulnerable countries due to its high dependence on agriculture and its coastal location. Increased atmospheric temperatures caused by climate change also significantly threaten one of Vietnam's most important cash crops, robusta coffee (Coffea canephora). Suitable cultivation sites of robusta, which comprises 97%...
Ralph Ellison died without ever completing his second novel. After his death, the executor of his literary estate, John F. Callahan, edited Ellison's work into a novel published under the title Juneteenth. This thesis examines the problems posed by Ellison's posthumously released text, especially the issues of authorial intent and...
Application of herbicides to the soil has become an important
factor in the production of row crops. Economic production
of sugar beet (Beta vulgaris), an important row crop, requires
efficient methods of weed control.
Two experimental herbicides, 3-cyclohexyl-5,6-trimethylene
uracil (DP634) and 2-bromo-6't-butyl-o-acetotoluidide (CP32179),
had shown promise in sugar beet screening...
Power planning efforts in Oregon require accurate information
about hydroelectric potential. Potential uses for Geographic Information
Systems (GISs) are being investigated by three Oregon planning agencies.
This paper presents a method in which a 616 is used to help identify and
reduce uncertainty in previous hydroelectric inventories. Uncertainty with
respect...
Physics sensemaking is a growing topic of study within the physics education community. Many lenses have been used to study sensemaking but few have considered how time and instruction can impact student sensemaking practices and ideas. In this dissertation, I present four studies that address four major questions: What sensemaking...
The problem of this study was to determine whether graduate students
in education (the experimentals) participating in a counseling
practicum would demonstrate a change in self-actualization which would
be significantly different when compared with other graduate students
in education (the comparisons) who were not participating in the above
program. The...
