This was a study designed to determine the occurrence of recovery
from radiation damage in Taricha granulosa. Irradiation with either
gamma or x-ray sources in the range of 96-10,000 rads was given. (The
mean or median survival times were determined.) Doses were fractionated
and the survival times for the same...
Weeping alkaligrass (Puccinellia distans) and Nuttall’s alkaligrass (Puccinellia
nuttalliana) infest Kentucky bluegrass seed fields of eastern Oregon. Weeping
alkaligrass is an introduced species from Eurasia, whereas Nuttall’s alkaligrass is
native to semi arid environments of western North America. These species are often
referred to collectively as ‘alkaligrass’; however, for farmers...
This thesis explores the metaphor of hospice nurses as "midwives to the dying" by
applying philosophical inquiry to the field of hospice. I focus on the history of the
movements, their professional approaches to caregiving, and the core commitments of
both the modern midwifery and hospice movements. Although focused on...

This was an experimental study which compared two different
instructional methods, oral lesson closure versus
written lesson closure, on the achievement of 156 junior
high school students in social studies. This study was
composed of two duplicate experiments. Experiment I was
conducted with 71 seventh grade social studies students at...
Creeping bentgrass (Agrostis stolonifera L.) is an outcrossing, small- seeded, perennial grass that can establish outside of cultivation and has several compatible relatives. Glyphosate is a nonselective, broad spectrum, herbicide. Transgenic glyphosate-resistant (GR) creeping bentgrass (GRCB) was developed by The Scotts Company and Monsanto, but is still under USDA-APHIS regulated...
A suspected glyphosate-resistant Italian ryegrass (Lolium multiflorum) (OR) population was collected from a filbert (Corylus avellana L.) orchard near Portland, OR. Based on the dose-response experiments conducted in the greenhouse, it was found that the suspected glyphosate-resistant population was approximately fivefold more resistant to glyphosate than the susceptible (S) population....
This dissertation describes the cloning and characterization of the TOUSLEDlike kinases genes of maize (ZmTLKs). The TOUSLED-like kinases (TLKs) are a conserved family of nuclear Ser/Thr kinases in higher eukaryotes. The maize genome has three TOUSLED-like kinase genes (ZmTLK1, ZmTLK2, and ZmTLK3). Based upon sequence similarity, the ZmTLKs are divided...
A preliminary study was conducted to establish baseline data for emu artificial egg incubation and emu chick growth and management. Three experiments examined factors affecting hatchability of emu eggs that occur prior to and during artificial incubation. Characteristics analyzed were egg storage duration, hen age, egg weight, egg index, shell...
The consumer as an active member of the marketplace has
gained much attention in past years. Information concerning specific
consumers is vital to those who are involved in consumer education.
The aged consumers are one group that gains much concern.
A sample of 25 aged persons in Corvallis was surveyed...
Research suggests that a key factor in student persistence and success is the relationships students form with faculty (Chickering & Gamson, 1991; Kuh et al., 2005; Tinto, 1987). While it appears to be intuitive that small classes would promote these instructor/student relationships, research on class size provides conflicting results, with...
