It was previously shown that vaccinia virus is unable to complete its replicative cycle in cells that have been subjected to cytochalasin-B mediated enucleation prior to infection. Likewise, in the presence of the drug α-amanitin, a potent inhibitor of host RNA polymerase II but not of viral transcription, the replication...
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
phospholipid...
The central purpose of this study was to identify the
competencies of a predeparture orientation program as determined by
business/industry personnel and personnel from institutions
representing the U.S. Agency for International Development. An
additional objective was to examine the organizational framework of
existing predeparture programs to identify instructional
methodologies, administrative...
Studies were conducted over a two year period to evaluate alternative
finishing methods for spring and fall-born beef cattle. Management
alternatives from birth to slaughter included season of calving, lactating
cow nutrition, preweaning calf nutrition, weaning age, calf and
yearling winter nutrition, range and irrigated pasture supplementation,
grazing practice, range...
A high speed motion neutron radiography system has been developed
at Oregon State University which is capable of taking high speed
neutron radiographs of events which occur on the order of one to two
milliseconds or more. This system was used previously to demonstrate
the application of high speed motion...
This study is a synthesis of the available ethnographic and relevant archaeological data pertaining to the Native American groups who formerly occupied the upper Rogue River drainage of southwestern Oregon. The information presented in this synthesis concerns the material, social and religious aspects of aboriginal life as practiced by the...
The response on the continental shelf of a baroclinic ocean to
driving by an alongshore coastal wind stress and by barotropic and
baroclinic wind forced interior motions is studied as a function of
latitude. The relative excitation of continental shelf waves and
internal Kelvin waves is studied.
The response of...
Experiments were conducted to determine both the influence of wood
moisture content on the fungitoxicity of methylisothiocyanate (MIT) to the
wood-decay fungus Poria carbonica, and the ability of gelatin to safely en-capsulate MIT for efficient treatment of wood products.
The fungitoxicity of MIT was studied by determining the product of...
The output characteristics of a conventional GaAs depletion-mode MESFET device have been investigated. One of the important parameters of the small-signal GaAs MESFET model, g[subscript ds] (output conductance), is shown to be frequency and temperature dependent. Variations in g[subscript ds] are a serious problem in many analog and digital circuits...
