The middle to upper Eocene Tillamook Volcanics form the basement in the Rock Creek - Rocky Point area. These tholeiitic to alkalic basalts, basaltic andesites, and andesites were erupted as shield volcanoes seaward of the strandline ontop of an older deep-marine mudstone unit (Yamhill Formation) and an accreted portion of...
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...
The opening of the South Atlantic between 140 and 90 m. y. B. P.
occurred about two poles of rotation. The initial pole of rotation was
maintained until Africa and South America were completely separated.
The subsequent removal of restraints imposed by the pre-existing
structure of Africa and South America...
The purpose of this study is to provide a systematic method to
analyze relationships between inputs, technology, and market structure
of an industry, and marketing activities among countries in general
and to develop an economic analysis of trade flow of the hardwood
plywood industry in the Far East exporting countries:...
Experiments conducted in the greenhouse showed that the leafhopper,
Colladonus montanus reductus (Van Duzee), is a long-day
insect. This conclusion is based on the production of diapausing eggs
when the leafhoppers were kept under short days (ten hours) during
the nymphal stage and the adult pre-oviposition period. Continuous
development of...
Rear brake calipers are a critical component of the brake system within a vehicle. Brake calipers function by clamping against the brake rotor when the brake pedal is pressed by the driver and thus results in deceleration of the vehicle. This thesis aims to design and develop custom rear brake...
Leafcutter ants cut trimmings from plants, carry them to their underground nests and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the amount of cutting is important in understanding foraging energetics. Estimates...
This dissertation examines the interaction of the linker histone with DNA and with nucleosomes. The first goal of the project was to characterize the interaction of the linker histone with DNA. Three factors previously reported to influence the linker histone's interaction with DNA were examined: ratio of linker histone to...
This thesis examines one aspect of social change in Nepal. Contact
with the outside world since 1951 has provided a non-traditional
means of achieving access to highly valued occupations, resulting in
the formation of an emerging elite. High caste status is no longer
absolutely necessary to gain access to education,...
Polyphenolic compounds found in foods such as fruits, vegetables, legumes, nuts and grains, are an integral part of the human diet. Within polyphenols, proanthocyanidins are referred to as condensed tannins and encompass procyanidins, propelargonidins and prodelphinidins. Among these, procyanidins are the largest group. Recent interest in these compounds is related...
