Cost effective medical isotope production is key to the success of many forms
of radiation therapy. A lymphoma clinical trial for copper-67 was canceled in 1997
due to insufficient production quantities of the isotope (Fast Flux Test Facility, 2001).
To date high flux thermal reactors and particle accelerator facilities have...
The conservation of declining desert fish species requires the identification of relations between fish population dynamics and their environments. Dynamic occupancy modeling, an approach that requires less information than traditional mark-recapture studies, may help identify important factors affecting population processes and aid desert fish conservation and restoration efforts. I used...
Suspended particulate matter (SPM) in the Columbia River is a mixture of particles of several origins having varying physical and biogeochemical properties. The relative abundances of these freshwater particles changes with season and apparently also with tide. Prior investigation has quantified seasonal variation of organic material in both the Columbia...
From 1979 through 1984 the economic bases of rural
Oregon counties have undergone structural change. Nonwage
income, especially transfer payments, has played an
important role in these changes. Demographic changes in
rural counties have contributed to the growth in unearned
income.
The economic structure of rural Oregon counties was
estimated...
This dissertation describes the cloning and characterization of the TOUSLEDlike kinases genes of maize (ZmTLKs). The TOUSLED-like kinases (TLKs) are a conserved family of nuclear Ser/Thr kinases in higher eukaryotes. The maize genome has three TOUSLED-like kinase genes (ZmTLK1, ZmTLK2, and ZmTLK3). Based upon sequence similarity, the ZmTLKs are divided...
Stripe rust (Puccinia striiformis f. sp. tritici) and Septoria tritici blotch (Zymoseptoria tritici) are a constant and significant threat to wheat production, significantly reducing wheat quality and yield. Wheat is responsible for 20% of the world’s human calorie intake, and wheat production must increase to supply the demand of the...
Lake Chad is an important fish supply centre in the semi-arid zone of West Africa. Processed Fish Trade (PFT) has catered neighbouring countries for a long time. However, Fresh Fish Trade (FFT) boomed due to severe droughts between 1970 and 1994, by which the PFT main fish species were replaced...
