Development and evaluation of conservation tillage for squash in Western Oregon

Creator:: Reich, Brandon M.
Abstract:: Squash varieties of Golden Delicious and Squash Hybrid NK 530 were grown in disk-till, strip-till, and no-till conservation tillage systems following a cover crop of'Monida' oats (Avena sativa L.) and common vetch (Vicia sativa L.). Tillage systems were evaluated for effects on squash emergence and yield, weed density and biomass,...

Neutron-irradiation effects on the V-I characteristics of YBa₂Cu₃O₇₋δ twinned crystals: Linking transport results in a variety of copper oxide superconductors

Creator:: Brown, Brandon, Roberts, J. M., and Tate, Janet
Abstract:: We have investigated the depinning process of magnetic flux vortices in twinned crystals of YBa₂Cu₃O₇₋δ in intermediate applied magnetic fields parallel to the crystallographic c axis through precise resistivity measurements before and after fast-neutron irradiation. Of particular interest for each field is the power-law dependence of the electric field on...

Scaling of thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] resistivity-current isotherms at low fields: Implications for vortex phase transitions and universality

Creator:: Roberts, J. M., Brown, Brandon, Tate, Janet, Xi, X. X., and Mao, S. N.
Abstract:: We have investigated a second-order phase transition of the vortex lattice in thin-film Nd₁.₈₅Ce₀.₁₅CuO[subscript 4-y] from 1 mT to 1 T applied magnetic fields. The dc resistivity-current density data for each field exhibit critical scaling consistent with a second-order vortex-liquid to vortex-solid phase transition. The high-field data support the vortex-glass...

Scaling of voltage-current characteristics of thin-film Y-Ba-Cu-O at low magnetic fields

Creator:: Roberts, J. M., Brown, Brandon, Hermann, B. A., Tate, J., and Tate, Janet
Abstract:: We have measured voltage-current characteristics for YBa₂Cu₃O₇ thin films in magnetic fields from 5 T to ambient, including some in the millitesla range. In all cases, the resistivity —current density isotherms can be separated into two classes: those which exhibit upward curvature, and have constant resistivity at low currents, and...

Quantitative trait locus mapping of yield and yield components in barley (Hordeum vulgare L.)

Creator:: Traore, Abdoulaye
Abstract:: Higher grain yield is a key objective in barley (Hordeum vulgare. L) breeding. Despite extensive research on the genetics of yield and its components, selection for yield per se is still the most extensively employed because of negative relationships among components, modest correlations between yield and any particular component, and...

Plate boundary deformation of the Pacific plate : two case studies

Creator:: Leitner, Beate
Abstract:: Two examples of Pacific rim plate boundary deformation are presented. In the first part of the thesis crustal models are derived for the northwestern part of the Vizcaino block in California using marine seismic and gravity data collected by the Mendocino Triple Junction Seismic Experiment. A northwest-southeast trending kink in...
