Polymer modified asphalts have recently been the focus of much
attention in the U.S. due to claims that polymer additives will
lengthen the life of an asphalt pavement. Much of the published
research on this topic has been concentrated on the effects of
polymer modifiers on binder and mixture properties....
Five experiments were conducted to investigate the
effect of dietary fish meal on the incidence of Sudden Death
Syndrome (SDS) in broiler chickens. Growth, feed
efficiency, total mortality and mortality due to SDS were
evaluated. Necropsy examination was performed on broilers
suspected of dying from SDS. Liver lipid and fatty...
The response of adjacent structural systems to earthquake motions is investigated using the finite element framework OpenSees. Results of sensitivity analyses demonstrate that structural response quantities can increase in either or both of the adjacent structures for specific configurations. The structural models used include steel moment-resisting frames and rigid shear...
To determine if 6 weeks prior supplementation with vitamins E and C
could alleviate exercise-induced DNA damage, prevent lipid peroxidation and
inflammation, slow the rate of vitamin E utilization and/or attenuate muscle
damage, 22 subjects (11 females: 11 males) were studied during a 50 km (32
mile) ultramarathon. Subjects were...
The biochemical composition of ten species of estuarine phytoplankton
was determined. Studies were made of their growth in
various culture media and of their relative value as food for oyster
larvae. Nine of the species were isolated from Yaquina Bay, Oregon.
An attempt was made to select species which commonly...
Approximately 200 raw prunes were harvested from each of five Italian prune trees near Corvallis every three days for nine consecutive harvest dates. Forty individual fruit from each tree were drawn at random and subjected to a series of fresh fruit quality tests.
For each quality factor which was measured,...
Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...
Many natural resources such as water and forests have become more intensively used in recent years. Often, this has made it necessary to reallocate these resources from less to more efficient productive usage. The knowledge of the existing tradeoffs between alternative uses are necessary to make reallocative decisions. However, these...
