  • 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...

  • The blueberry : composition, anthocyanins, and polyphenolics

    Creator:
    Lee, Jungmin
    Abstract:
    Frozen blueberries were pilot-plant-processed into juice and concentrate by 2 treatments (heat and SO2), and a control. Qualitative, and quantitative anthocyanin and polyphenolic content were monitored after each processing step. Major losses occurred after the initial processing steps. Juice processing by-product contained a substantial amount of anthocyanins and polyphenolics (>42%...

  • 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...

  • Use of Controlled Blasting to Quantify the Dynamic, In-Situ, Nonlinear Inelastic Response of Soils

    Creator:
    Jana, Amalesh
    Abstract:
    The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...

  • Applications of Soil Science in Forest Landscape Planning : Challenges and Opportunities in the 21st Century

    Creator:
    Craigg, Terry Lee
    Abstract:
    Soils and other resource programs in both public land management agencies and private industry are continually being adapted to the challenges of evolving knowledge and experience in the field of forestry. This dissertation explores new ways of thinking about and using soils information in forest planning and management, with a...

  • The photochemistry of some insect juvenile hormone analogs

    Creator:
    Siggel, Lorenz
    Abstract:
    The photochemistry of some analogs of insect growth regulators (IGR's) was studied. Methyl geranate, TY, was synthesized and the mechanisms of its photochemical reaction pathways were studied by a variety of techniques. Direct irradiation of 71 in ether leads to the formation of five new products: 98, the product of...

  • An approach toward the synthesis of euonyminol and cathedulin K- 19

    Creator:
    Shin, Hyunik
    Abstract:
    A synthetic approach toward the two major fragments of cathedulin K-19, euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran sesquiterpene, was advanced to a stage in which...

  • What is killing the corals? Viral and bacterial interrogations using metagenomics and microscopy

    Creator:
    Soffer, Nitzan
    Abstract:
    Corals have multiple roles in maintaining ocean health and are some of the world’s most diverse ecosystems. The coral animal is host to a multitude of taxa, including symbiotic dinoflagellate algae, fungi, bacteria, protists, and viruses. Environmental stressors and disease agents can perturb the delicate balance of the coral host...

  • Treatment of dairy wastewater in a constructed wetland system : evapotranspiration, hydrology, hydraulics, treatment performance, and nitrogen cycling processes

    Creator:
    Niswander, Steven Francis
    Abstract:
    Five unique but related studies were conducted at the Oregon State University Dairy Wetland Treatment System (OSUDWTS), Corvallis, OR. The research site consisted of six parallel wetland cells, which were built in 1992 and began receiving concentrated dairy wastewater in the fall of 1993. Hydrologic, hydraulic, and water quality data...
