Reversible Covalent Immobilization of Desferrioxamine B (DFOB) on Aminated Polystyrene Beads for Citrate-Bound Fe(III) Chelation

Creator:: Touma, Jad G.
Abstract:: The immobilization of chelators to solid supports has recently gained renewed interest due to the increasing biomedical and environmental applications made possible by these molecules’ ability to bind Fe(III) and other metal ions. The uses of immobilized chelators have expanded to include the treatment of metal overload in serum, the...

Design and Testing of a Device to Separate Tightly-Bound and Mobile Water Pools in Soil

Creator:: Madrigal, Justin Luis
Abstract:: Water movement, from forest soil to streams, has traditionally been modeled by translatory flow. A hypothesis was presented by Brooks et al. (2010) suggesting that, in addition to translatory flow, there exists an immobile pool of water trapped in small pores with low matric potential. Comparisons of water stable isotope...

Characterization of soil carbon and nitrogen pools following a decade of detritus manipulation in a temperate coniferous forest

Creator:: Wilson, Lea I.
Abstract:: Soil organic matter (SOM) is the result of the balance between decomposition and incorporation of detritus from both above and below ground sources into the soil. It composes only a fraction of the soil by mass but it is one of the most critical components. The Detritus Input and Removal...

Reactive polyphenols and dissolved nutrients in a nitrogen-limited headwater catchment, western Cascades, Oregon, USA

Creator:: Rasmussen, Janet K.
Abstract:: In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

Dissolved Organic Carbon Production and Flux from Long Term Litter Manipulations in a Pacific Northwest Old-Growth Forest

Creator:: Evans, Lucas R.
Abstract:: Dissolved organic carbon (DOC) flux is an important mechanism to convey soil carbon (C) from aboveground organic debris (litter) to deeper soil horizons and can influence the formation of stable soil organic carbon (SOC) compounds. Aboveground litter quantity and quality was manipulated for 20-years in an old-growth Douglas fir forest...

Bioactive and Biocompatible Coatings for Endotoxin Capture in Treatment of Sepsis

Creator:: Su, Jonathan
Abstract:: Sepsis is a blood infection caused by circulating pathogens and cell wall fragments that affects over 1 million patients per year in the United States. When bacterial cell membranes are lysed by antibiotics, cell wall fragments containing lipopolysaccharides (LPS) are released. As a result, the capture of LPS is critical...

Homogenization of Detrital Leachate in an Old-Growth Coniferous Forest, OR : DOC Fluorescence Signatures in Soils Undergoing Long-Term Litter Manipulations

Creator:: Strid, April R.
Abstract:: Soil dissolved organic carbon (DOC) is a small but crucial part of the forest carbon cycle. Characterizing the relationship between detrital inputs and soil DOC chemistry is crucial to understanding the ultimate fate of root carbon, fallen wood and needles. Chemical differences in the DOC pool may help to explain...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Surface-Initiated Click-Ready Bioactive Polymer Coatings: Synthesis and Characterization

Creator:: Yu, Bonan
Abstract:: Protein adsorption on blood contacting medical devices usually causes fouling and failure, and may promote clotting and undesirable immune responses. Hydrophilic polymer coatings in a dense, pendent “brush” conformation can resist protein adsorption on the surface while increasing biocompatibility. Such coatings can also be used to immobilize a variety of...

The production of dissolved organic carbon (DOC) over time with change in substrate type, temperature, and mineral soil inclusion

Creator:: Stanton, Alexandria H.
Abstract:: Dissolved Organic Carbon (DOC) originates from organic matter. Climate and vegetation have been found to alter DOC production. The goal of this study was to determine where the differences in DOC production originate from. Mineral soil and substrate including maple leaves, needles, old wood, and sticks were collected from the...
