Phenology and monitoring of the cabbage maggot, Delia radicum (L.), in brassica root crops

Creator:: Dreves, Amy J.
Abstract:: In Oregon’s northern Willamette Valley, cabbage maggot (CM), Delia radicum (L.) (Diptera: Anthomyiidae) often renders Brassica root crops unmarketable. Scheduled insecticides are the only current control. Studies were conducted to: 1) describe and characterize spring emergence of CM flies and their seasonal flight activity relative to degree-day (DD) accumulations; 2)...

A GIS approach to estimating continuous hydraulic conductivity and equivalent hydraulic conductivity

Creator:: Arras, Tracy Lynn
Abstract:: Estimating the hydraulic conductivity of earth materials is important for many water resource modeling efforts, including predicting the transport of pollutants in ground water, computing surface runoff for flood control, and computing water budgets. This research implicitly used topography, soil, and climate data to estimate plausible continuous hydraulic conductivity values...

Distribution of Oligonychus (Oligonychus) ununguis (Jacobi) (Acari: Tetranychidae) and predator mite species (Acair: Phytoseiidae) on field-grown Douglas-fir (Pseudotsuga menziesii [Mirb] Franco) Christmas trees

Creator:: Calkin, James D.
Abstract:: The shake and wash technique (samples placed in a jar with alcohol added and shaken to remove the mites) was effective in removing 100% of the predator mites, and adult spruce spider mites from Douglas-fir foliage and 98% of the spruce spider mite nymphs. Eighty-eight percent of the spruce spider...

Appendix D - Stable Isotope Data.pdf

Creator:: Hornung, Jonathan P.
Abstract:: Deep-sea bamboo coral (Isidella sp.) SE000901A from the southern Oregon coast (water depth 1048m) provides a high-resolution record of variability of North Pacific Intermediate Water (NPIW) and carbon rain to the sea floor, related to coastal upwelling, from 1808 to 2000AD. Counting of annual layers in magnesium to calcium (Mg/Ca)...

A Bayesian Treatise on the Replication Crisis in Science

Creator:: Gibson, True E.
Abstract:: Over the past decade, it has come to light that many published scientific findings cannot be reproduced. This has led to the replication crisis in science. Many researchers feel that they can no longer trust much of what they read in scientific journals, and the public is becoming ever more...

Anaerobic reductive dechlorination of TCE and TCFE in TCE contaminated sediments : enhanced bioremediation and bioaugmentation

Creator:: Lee, Jae-Hyuk
Abstract:: This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...

Quantitative, multi-spectral, light-transmission imaging of colloid transport in porous media at the meso scale

Creator:: Kraft, Erika Lorna
Abstract:: Colloids, particles smaller than ten microns in diameter, are ubiquitous in the subsurface. Colloids have an effect on the transport of contaminants that bind to their surfaces, and can reduce the permeability of aquifer materials through deposition. Some microorganisms, including pathogens, are also transported in the subsurface as colloids. The...

The Influence of Entrepreneurs’ Physical and Cognitive Traits on Entrepreneurial Outcomes

Creator:: Farah, Nusrat
Abstract:: The dissertation examines the effect of two separate yet significant individual level factors—physical and cognitive traits—on entrepreneurial outcomes. The physical factor on which the dissertation focuses is the entrepreneur’s vocal cues and the cognitive traits that the dissertation investigates are the entrepreneur’s goal orientation and his/her ability to take perspectives....

Uranium and technetium bio-immobilization in intermediate-scale permeable reactive scale barriers

Creator:: Sapp, Mandy M.
Abstract:: Groundwater at Oak Ridge National Laboratory's Field Research Center (FRC) is contaminated with U(VI) and Tc(VII), has pH values as low as 3.3, and nitrate concentrations as high as 120 mM. The objective of this research was to determine if in-situ bio-immobilization is a viable treatment alternative for this water....

Field and greenhouse studies with Acalymma and Diabrotica : protection of cucurbits with a kaolin-based particle film : feeding damage to cucumbers with and without cucurbitacin

Creator:: Reich, Joel A.
Abstract:: Research was conducted in the field and greenhouse to determine if a kaolinite-based particle film, Surround®, would reduce colonization and early season feeding damage in cucurbits by the Western Striped Cucumber Beetle, Acalymma trivitattum (Mannerheim). Greenhouse studies were designed to determine effect of particle film on cucumber dry weight production...
