The 109-year-old Porter house in Shedd, Oregon is one of few
remaining, well-preserved examples of Rural Gothic architecture in the
Willamette Valley. This study attempts to record its history: the
economic circumstances which led the pioneering David Putnam Porter
family to build this relatively large house, the family background,
and...
The buildup of reactive oxygen species (ROS) and reactive nitrogen and oxygen species (RNS) is known as oxidative stress. Oxidative stress results in a wide variety of modification to biological macromolecules including nucleic acids, lipids, and proteins. For at least 30 years it has been known that high levels of...
The process of de-excitation of the actinides is a very important question in both pure and applied science. In this dissertation the process was studied using the neutrons emitted in coincidence with fission induced by the bombardment of ²³⁸U with 14.85 MeV deuterons. Neutrons can be emitted at multiple stages...
Community colleges today are experiencing monumental shifts in their operating
environments. Some of these changes are known, but many of them are not. They
include shifts in curriculum, funding, and societal expectation to name a few. Through
the constructs of high quality work environment and organizational fluidity theory, this
research...
The production of C¹⁴O₂ metabolized from glucose labeled in
specific carbon atoms by homogenates of chick embryonic and adult
heart was compared by the radiorespirometric technique. Homogenates
of early (two to five days of incubation) embryo hearts were
found to utilize the phosphogluconate pathway of glucose catabolism
to a greater...
Although surface water constitutes less than 1.5% of freshwater supply, historical development of surface water sources continues to mark the landscape. However, over- exploitation of groundwater is now at its highest, and 25% of the world’s 1.7 billion population live in water scare regions. As glaciers and snowpack disappear due...
