A Study of Early Holocene Paleoprecipitation Record from Freshwater River Mussel Shell at the Cooper's Ferry Site, Idaho and Their Archaeological Implications

Creator:: Jimenez, Alejandra P.
Abstract:: Studies of δ¹⁸O held in freshwater bivalve shell carbonate are useful for reconstructing paleoclimates and environmental changes and inform interpretations about past human behavior and periods of culture change. Stable isotope analyses (δ¹⁸O) of Margaritifera falcata shells found at the Cooper's Ferry archaeological site located in the lower Salmon River...

Ecology of harlequin ducks in Prince William Sound, Alaska, during summer

Creator:: Dzinbal, Kenneth A.
Abstract:: Harlequin ducks (Histrionicus histrionicus) were observed during the summers of 1979 and 1980 in Sawmill Bay, northeast Prince William Sound, Alaska. Harlequins were associated with a short, medium gradient, non-glacial stream (Stellar Creek) also used by salmon. Although harlequins nested along Stellar Creek, they apparently did not establish home ranges...

Effect of a broccoli green manure, soil solarization, and isolates of Verticillium dahliae on Verticillium wilt of agronomic and nursery crops

Creator:: Berlanger, Ingrid E.
Abstract:: Green manures, soil solarization, and long rotations with crops not susceptible to Verticillium wilt are among the disease management tactics currently under investigation as alternatives to chemical fumigation of soil. The effect of a broccoli green manure on soil microsclerotial populations of three isolates of Verticillium dahliae and on Verticillium...

Descriptive Analysis of Human Remains from the Fuller and Fanning Mounds, Yamhill River, Willamette Valley, Oregon

Creator:: Stepp, David
Abstract:: The study presents the results of a descriptive analysis of the skeletal remains of 66 individuals recovered from the Fuller and Fanning Mound sites, located on the Yamhill River, Willamette Valley, Oregon, excavated in 1941-42 by W. T. Edmundson and William S. Laughlin. The literature and original field notes have...

The use of ⁶⁰Co cell survival curves in BNCT research

Creator:: Johnson, Jennifer Elizabeth
Abstract:: The cell survival curve is the only means by which to both qualitatively and quantitatively assess morphologic alterations directly resulting from in vitro irradiation of the cell. A ⁶⁰Co cell survival curve experiment has successfully demonstrated the response of the AtT-20 clone mammalian cell line to the effects of gamma...

Influences of riparian canopy on aquatic communities in high desert streams of eastern Oregon

Creator:: Tait, Cynthia K.
Abstract:: Because riparian canopy controls most energy inputs to stream ecosystems, it directly affects the structure of aquatic food webs and the ecological processes that govern interactions among trophic levels. This study addresses the interdependence among riparian canopy, benthic community structure, and the carrying capacity of high desert streams for salmonid...

The oligocene and miocene geology of the Tillamook embayment Tillamook County, northwest Oregon

Creator:: Parker, Michael J. (Michael John), 1958-
Abstract:: Eleven sedimentary and volcanic rock units are mapped and described in the thesis area, and chronicle the dynamic geologic history of the Tillamook embayment from the Oligocene through the middle Mlocene. The oldest unit is the Zemorrian to early Saucesian Smuggler Cove formation, a bathyal tuffaceous mudstone with some thin-...

Hydrogeologic field investigation and groundwater flow model of the southern Willamette Valley, Oregon

Creator:: Craner, Jeremy D.
Abstract:: Elevated groundwater nitrate (NO3 -) concentrations in the Southern Willamette Valley (SWV) caused the Oregon Department of Environmental Quality (ODEQ) to declare a Groundwater Management Area (GWMA) in Spring, 2004. To better understand direction of groundwater flow, groundwater age, and nitrate transport pathways of the SWV we developed a steady-state...

Cytokinin antagonists and antibiotics related to nalidixic acid : effects on Phaseolus and Nicotiana callus tissues

Creator:: Marsden, Katherine E.
Abstract:: The effects of five cytokinin antagonists on the growth of cytokinin-autonomous lines of Phaseolus lunatus cv. Kingston, Phaseolus vulgaris cv. Great Northern, and Nicotiana tabacum cv. Wisconsin 38 callus tissues have been compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines bearing the following N⁴ side chains, 4-n-pentyl- (ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...

The acute effects of moderate intensity circuit weight training on lipid-lipoprotein profiles

Creator:: Lee, Young-soo
Abstract:: Few studies have examined the acute effects of resistive-type exercise on lipid-lipoprotein profiles. This study examined the acute effects of a single session of circuit weight training (CWT) on plasma lipid-lipoprotein profiles: triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and the ratio...
