Dormancy and germination of true potato (Solanum tuberosum L.) seeds : characterization of endo-β-mannanase genes

Creator:: Monteros, Alvaro R.
Abstract:: True potato (Solanum tuberosum) seed (TPS) is used for preservation of variable genetic lines of wild and cultivated potatoes (Hawkes et al., 2000) and for propagation of food crops in some developing countries. TPS has advantages over seed potato tubers in storage and transportation and favors lower virus infection levels...

Prediction and Measurement of Polycyclic Aromatic Hydrocarbons (PAHs) Transformation Products in the Environment.

Creator:: Titaley, Ivan A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental contaminants consisting of fused benzene rings. Parent-PAHs, methylated-PAHs (MPAHs), and PAHs with molecular weight of 302 a.m.u (MW302-PAHs) are considered as unsubstituted-PAHs. These unsubstituted-PAHs undergo transformation reactions resulting in the formation of PAH-transformation products (PAH-TPs), or substituted-PAHs, including nitrated-, oxygenated-, and...

Development of Diagnostic Assays for Race Differentiation of Podosphaera macularis

Creator:: Block, Mary H.
Abstract:: Hop powdery mildew (Podosphaera macularis) was confirmed in the Pacific Northwest in 1996. Before 2012, the most common race of P. macularis was able to infect plants that possessed powdery mildew resistance based on the R-genes Rb, R3, and R5. Post 2012, two additional races of P. macularis were discovered...

An Ecoregion-Based Reference Condition and Classification Scheme for Determining Nutrient Criteria in Oregon Lakes

Creator:: Brenner, Jacqueline M.
Abstract:: The anthropogenic introduction of nutrients to water bodies has been shown to alter the structure and function of natural aquatic ecosystems, yet national EPA lake and reservoir nutrient criteria remain too broad for effective regional water quality management. This study uses a reference site approach to propose numeric nutrient criteria...

Dosimetric verification of respiratory gated radiation therapy for tumors involving the lung

Creator:: Webb, Lindsey S.
Abstract:: As the field of radiation therapy evolves new treatment techniques will be established. An example of an evolving treatment technique is respiratory gated radiation therapy (RGRT). Research and studies have shown that RGRT can be used to account for tumor motion as a result of respiratory motion. With evolving technology...

Using Computational and Statistical Methods as an Aid to Study Environmentally Relevant Organic Molecules

Creator:: Dorn, Shelby E.
Abstract:: In this report, three studies are presented that utilize computations to predict transformations, identities, and properties of environmental organic molecules. Each study shows how computations can lead to models of chemical behavior. The importance of this research is rooted in the need for understanding how human behavior and health intersect...
Resource Type:: Masters Thesis
Full Text:: toxicity. Four approaches are compared to experimentally observed PAH-TP formation; these four approaches

Potential Additive-Manufacturing of Ablative Thermal Protection Systems

Creator:: Hazell, Kenya K.
Abstract:: Electrodeposition is a versatile polymer deposition technique to create nano-microscale materials using an electrical field generated from a charged droplet of solution and a grounded collector. Electrospinning or electrospraying can occur during electrodeposition, leading to the creation of nanofibers or bead-like materials depending on the process parameters. Photopolymerization of the...

Developmental effects of micro- and nanoscale tire particles and recycled rubber on zebrafish

Creator:: Mottern, Taylor H.
Abstract:: Plastics have become an essential part of everyone lives, found in almost every product made today. Tires only make up a fraction of these products but as their use increasing so does the microplastics that flake off. Many studies have evaluated the toxic effects of tire particles on aquatic environments...
Resource Type:: Honors College Thesis
Full Text:: particles (TP) created from road abrasion have caused an estimated 5-10% of global plastics to end up in

Total synthesis of sparteine alkaloids from a common tetraoxobispidine intermediate

Creator:: Melbardis, John
Abstract:: In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...

Effects of timing and duration of flooding on phosphorus release in four restored wetlands around Agency and Upper Klamath Lakes, Oregon

Creator:: Stevens, Carla J.
Abstract:: Upper Klamath Lake (UKL) and Agency Lake in south-central Oregon are hypereutrophic due to phosphorus (P) loading from both geologic and agricultural sources in the watershed. Restoring historic lake-fringe wetlands to provide P sinks around the lakes has been accepted as a favorable means of reducing lake P levels and...
