Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

Creator:: Michalsen, Mandy M.
Abstract:: Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...

On Undular Bores and Solitary Waves in Variable Depth

Creator:: Knowles, Jeffrey N.
Abstract:: Numerical results are presented using a higher-order pseudo-spectral method in order to solve the Zakharov-Craig-Sulem formulation of the Euler model. We study the effects of variable bathymetry on weakly-dispersive, weakly-nonlinear, shallow water waves. Improved predictions on wave amplitude and shoaling behavior are developed by analytical means in the context of...

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Correlations between horticultural characteristics and Fusarium root-rot resistance in Phaseolus vulgaris L.

Creator:: Wang, Theodora
Abstract:: To study the association between Fusarium root-rot resistance (Fusarium solani f. sp. phaseoli) and economically inportant characteristics of beans, 2259 lines each consisting of 30 plants were used. The lines were randomly selected for root-rot reaction, but were selected for differences in vigor and differences in plant and seed pigments,...

Impact of sheep density and grazing duration on forage use in tall fescue-subclover hill pasture

Creator:: Ali, Eltom E.
Abstract:: A study investigating the effect of sheep stocking density and grazing duration on forage intake, grazing efficiency, dietary selectivity and subsequent forage accumulation in tall fescue(Festuca arundinacea)- subclover(Trifolium subtaranium) pastures was conducted near Corvallis, Oregon during early and late spring in 1988 and 1989. Grazing treatments were 2, 6, and...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
