The seasonal distribution of bioavailable organochiorine contaminants in surface
water and the potential environmental factors influencing their bioavailability were
evaluated. The study was carried at the lower Willamette River at Portland Harbor, Oregon
where surface water runoff varied according to season. Bioavailable water concentrations of
DDTs and PCBs were determined...
The primary goal of this study is to access the processes that alter primary melts after segregation from a mantle source and ultimately form petrologic Layers 2 and 3 of the Ocean Crust. Mineral, melt inclusion, and whole rock chemical compositions are utilized to further the understanding of 1) the...
Two econometric models were developed to forecast consumption,
production, and price of hardwood lumber, and removals and price
of hardwood sawlog stumpage. Four eastern U.S. regions were represented
in the models. Hardwood lumber consumption by manufacturing,
shipping, residential construction, and nonresidential construction
industries was recognized. Hardwood sawlog stumpage removals from...
Existing forest site maps have been described as "invaluable
tools" in forest management. Their, economic value potentially materializes
as the summed advantage from better decisions in all phases of
forestry.
Via Bayesian decision analysis, this study establishes optimal
use and economic value of site information for one facet of management...
The main purpose of this study was to investigate and describe strategies that Thai ninth grade students use to solve algebra word problems. The second purpose of this study was to investigate teachers' instruction during word problem solving lessons. Three mathematics teachers and one of each of their classes participated...
A backward fall is a major cause of hip fractures. Hip fractures have the potential to increase the mortality rate of older adults. Thus, the prevention of backward falls by older adults is a critical subject to be studied. Specifically, it remains unknown what effect aging-related losses in muscle strength...

In this dissertation I study evolutionary patterns at genes encoding antimicrobial peptides (AMPs) in frogs. AMPs are short, amphipathic, cationic, secreted proteins that kill bacteria and other pathogens through a non-catalytic mechanism that involves
binding to and disrupting the microbial cell membrane. In many animal taxa, positive selection is much...
The pharmacokinetics and dose proportionality of ibuprofen were examined in African and Asian elephants after single dose administration of 4, 5 and 6 mg/kg and on multiple dose administration. Each elephant received all the three doses and plasma ibuprofen concentrations were measured by HPLC. Approximate linearity of ibuprofen pharmacokinetics in...
