Design and application of a microcomputer automated multielement flame atomic fluorescence instrument

Creator:: Neyzari, Shahrokh Ghaffari
Abstract:: An automated multielement flame atomic fluorescence (AF) spectrometer based on microcomputer control was constructed to determine four elements simultaneously. The instrument employs a multiple exit slit monochromator where the light from various exit slits is directed to a single detector with a mirrored funnel. Each element is excited to fluoresce...

Invasion by trees into a grassy bald on Marys Peak, Oregon Coast Range

Creator:: Magee, Teresa K.
Abstract:: Grassy balds are meadows that occur on or near the summits of montane peaks and ridges. The sites on which balds are located generally fall within the climatic tolerance ranges of associated tree species. This study evaluates the stability of a forest-meadow transition zone of such a bald on Marys...

Aflatoxin mutagenesis and metabolism and their dietary modification in rainbow trout (Salmo gairdneri)

Creator:: Coulombe, Roger A.
Abstract:: Aflatoxin B₁ (AFB₁) is a mold-produced toxin which has been shown to be a potent hepatocarcinogen in many animal species. Of the species studied thus far, rainbow trout have proven to be the most sensitive. Experiments were conducted to investigate various aspects of AFB₁ metabolism in this species, including in...

The relative effects of Ceratomyxa shasta on crosses of resistant and susceptible stocks of summer steelhead

Creator:: Wade, Mark
Abstract:: Crosses were made between a stock of summer steelhead (Salmo gairdneri) known to be resistant to infection by Ceratomyxa shasta and stocks of summer steelhead known to be susceptible. Ceratomyxosis, the disease caused by C. shasta was initiated by exposure to Willamette River water. I found that the crosses were...

Distribution of fishes and their relationships to environments in selected coastal streams, Douglas and Coos Counties, Oregon

Creator:: Duke, Stephen D'Wayne
Abstract:: This study was an investigation to determine the distribution, abundance and general food habits of salmonids and non-game fishes residing in several selected coastal streams, Douglas and Coos Counties, Oregon. The physical conditions that characterize the various stream habitat types were monitored and the influence of physical conditions on the...

The winter distribution, movement, and smolt transformation of juvenile coho salmon in an Oregon coastal stream

Creator:: Rodgers, Jeffrey D.
Abstract:: The abundance of the 1982 brood of juvenile coho salmon (Oncorhynchus kisutch) was determined in August 1983, and January and April 1984 at 20 study sites spread throughout Knowles Creek, an Oregon coastal watershed. The timing of emigration of juvenile coho from the watershed was monitored from October 1983 through...

Speciation of inorganic arsenic by hydride generation atomic absorption spectroscopy

Creator:: Ikeda, Marcia Sakiko
Abstract:: A sensitive technique for the determination of As(III) and As{V) at μ/L and sub-μg/L concentrations from a single sample aliquot has been developed. This technique is based on the hydride generation atomic absorption (HGAA) spectrophotometry. The hydrides of the arsenic species are generated in a reaction vessel by mixing the...

Purification and characterization of a DNA polymerase gamma from human trophoblast tissue

Creator:: Wong, Scott W.
Abstract:: DNA polymerase gamma has been purified over 67,500-fold from human trophoblast tissue. Purification was achieved through successive chromatographies on phosphocellulose, DEAE-cellulose, DNA-cellulose, and high pressure gel exclusion through Fractogel TSK HW55. This preparation yielded a specific activity of 81 units/mg of protein using the preferred template-primer, poly (A)-oligo (dT)₁₂₋₁₃. Analysis...
