Composition and structure of Oregon ash
(Fraxinus latifolia) woodlands in the William L. Finley
National Wildlife Refuge, Oregon are described. Twenty
stands dominated by Fraxinus latifolia were sampled with
500 m2 circular macroplots in which floristic microplot
data were collected for plant community synthesis. Plant
communities were identified by computer-assisted...
An in vitro study was conducted to investigate the metabolism and distribution of Se⁷⁵-selenite and Se⁷⁵-selenomethionine (SEM) in
chick blood. Se⁷⁵-selenite is taken up by RBC (13% within 20
minutes) and expelled into the plasma to become bound to proteins. In
contrast, Se⁷⁵-SEM showed a more gradual and continuous buildup...
For my CSSA portfolio, I developed a graduate-level education course about disability in the United States and in higher education. In this paper, I will provide an introduction to my life and work in disability support services, and how my experience as a disability support services professional and graduate student...
Microbial communities in Arctic coastal lagoons drive biogeochemical cycles at the terrestrial-marine interface and help to determine the fate and form of resources like nitrogen (N) and carbon (C) as they are delivered to the Arctic Ocean. Though rising rates of primary production in the Arctic Ocean are well-characterized, the...
The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...
An adaptive pitch axis autopilot design procedure is presented. The
design procedure is applicable to both stable and unstable pitch axis models
and to those having nonminimum phase. The design approach assumes
the adaptive autopilot is activated after achieving level flight. It is shown a
rate-feedback compensator can be designed...
The United States is becoming a service oriented nation. As
increasing amounts of the gross national product are spent on services,
it becomes vitally important to ensure the productivity of these
services. The purpose of this thesis is to identify which elements are
needed in a service department productivity measurement...
One group of four adult White Leghorn male chickens was fed a
diet containing 7.3% linoleic acid and 32.4 mg/ kg of added vitamin E
(group IV) for 50 weeks which was designated as the positive control.
A second lot (group I) containing 14 males received the same level of...
