For Pacific salmon, the evolution of local adaptations depends upon the species' propensity to return, or "home", to natal streams at time of reproduction. Pacific salmon use olfactory cues to guide homing behavior, yet little is known about the genetics of olfaction in salmon. In this study, I use putatively...
Herbs have been used for many centuries in diverse civilizations for the treatment of heart disease. Only a few natural supplements claim to have direct cardiovascular actions including hawthorn (Crataegus spp.) and berberine derived from the Berberidaceae family. Several different studies indicate important cardiovascular effects of hawthorn and berberine. For...
The efficiency of cellulose hydrolysis under straight saccharification and simultaneous saccharification and fermentation (SSF) conditions was evaluated using three lignocellulosic materials (switchgrass, cornstover, and poplar), which had been pretreated with dilute sulfuric acid under conditions which optimized xylose concentrations in the prehydrolysate liquid. Yields of glucose, cellobiose and ethanol obtained...
This thesis summarizes an investigation into the need for removing extractives
from herbaceous biomass feedstocks prior to their chemical characterization. Switchgrass
(Panicum virgatum), was used in this study as a representative herbaceous biomass
feedstock. The influence of extractives on the chemical analysis of switchgrass was done
by comparing the composition...
Oregon English sole catch data from 0 to 80 fathoms between Coos
Bay and Cape Lookout were examined for the years 1973, 1975, and 1976.
English sole is a major target species of this inshore trawl fishery.
Comparison of depths of maximal values of catch per unit effort, effort,
and...
Endogenous circadian clock regulation is essential to normal rhythmicity, particularly the timing of hormone release in the brain. In the context of mammalian reproduction, a surge of a specific hormone, gonadotrophin-releasing hormone (GnRH), initiates a surge of luteinizing hormone (LH) from the pituitary gland, which is required for ovulation in...
Optimization programming techniques were applied to
develop the least cost formulations for Pacific whiting
surimi-based seafood (PWSBS). To develop the quality
constraint functions, texture and color of whiting surimi
gels were determined by torsion test and colorimeter,
respectively. Whiting surimi gels were produced by heating
at 90°C for 15 min....
Contamination of ground water by non-aqueous phase liquids (NAPLs) has
received increasing attention. The most common approach to numerical modeling of
NAPL movement through the unsaturated zone is the use of the finite difference or finite
element methods to solve a set of partial differential equations derived from Darcy's law...
