The Influence of grazing on active γ-Proteobacteria cells

Creator:: Wilson, Michelle Juliette
Abstract:: By identifying the relationships between abundance and metabolic activity in a bacterial community, we advance our knowledge of the marine carbon cycle. In the present study, our goal was to examine the role of protist grazing on the metabolic activity of γ- Proteobacteria in the upwelling system off the Oregon...

Determining and Characterizing the Efficacy of Superabsorbent Polymer for Wildfire Resistance Applications

Creator:: Kawasaki, Charles T.
Abstract:: Climate change is a pertinent issue causing an increase in the quantity and severity of wildfires. Current market solutions to protect homes from wildfires are expensive and do not always guarantee the safety of the home. Superabsorbent polymer (SAP) is a cross-linked polymer that can absorb over 100x its weight...

Degradation of N-Nitrosodimethylamine Using Photo-Catalysis and Microreactor Technology : Experimentation and Modeling

Creator:: Omar, Mohamed
Abstract:: The cleanliness of water is a major issue with regards to humanity's continued survival. The chlorination and chloro-amination of water is essential to the creation of microbiologically clean water. However these processes also give rise to oxidative byproducts such as nitrosamines. In particular, due to its high toxicity, N-Nitrosodimethylamine (NDMA)...

The influences of remote learning on assessments and student engagement

Creator:: Preusser, Deja
Abstract:: As a result of the COVID-19 pandemic, most colleges and universities around the world were forced to switch to remote learning. Many instructors were provided little guidance regarding how to restructure their courses for the remote classroom. The purpose of this study was to understand how the shift from in-person...

Molecular and rheological characterization of hyaluronic acid : determination of its role in thrombin-catalyzed fibrin clotting and viscosupplementation of joints

Creator:: Barrett, Brandon J.
Abstract:: Three samples of the biopolymer hyaluronic acid (HA) were characterized in the following manner: the molecular weights were obtained via multi-angle laser light scattering; the intrinsic viscosities were calculated through dilute solution viscometry, and the rheology of HA solutions was determined with constant rate rotational viscometry and dynamical mechanical testing....

The uptake, transformation, and physiological response of the marine red macroalga Portieria hornemannii to the nitroaromatic explosive 2,4,6-trinitrotoluene (TNT)

Creator:: Cruz-Uribe, Octavio T.
Abstract:: The capability of the marine red macroalga Portieria hornemannii to remove and detoxify the nitroaromatic explosive 2,4,6-trinitrotoluene (TNT) in a seawater environment was evaluated using an axenic microplantlet suspension culture system. Microplantlets were challenged with TNT dissolved in seawater at concentrations of 1 to 50 mg L-1 in well-mixed photobioreactors...

Nutrient Addition Strategies for the Marine Diatom Cyclotella sp to Control Cell, Lipid, and Chitin Formation.

Creator:: Chiriboga Novillo, Omar Guillermo
Abstract:: Marine diatoms are unicellular photosynthetic organisms that produce unique nanomaterials, energy dense lipid-molecules, and specialty carbohydrate molecules that can be all extracted from a single microorganism. The centric marine diatom Cyclotella sp. was used as a model organism for cultivation in a biorefinery system, where multiple co-products can be harvested...

Synthesis and function of bioactive, block copolymer surfactant constructs as relevant to the preparation of anticoagulant and antibacterial medical implant surfaces.

Creator:: Joshi, Pranav R.
Abstract:: Nisin, an antibacterial peptide proven to be an effective inhibitor of Gram-positive bacteria, was incorporated into novel block copolymer constructs and tested for retained antibacterial activity. Covalent coupling was achieved by chemical modification of the N-terminal isoleucine to introduce a thiol group. Thiolated nisin derivatives were then linked to poly[ethylene...

Nisin adsorption to PEO-PPO-PEO tri-block copolymer layers and its resistance to elution by fibrinogen

Creator:: Ryder, Matthew P.
Abstract:: While hydrophobic surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] (PEO-PPO-PEO) surfactant Pluronic® F108 are highly resistant to plasma protein adsorption, the antimicrobial peptide nisin has been observed to adsorb in multilayer quantities at such surfaces, and the PEO chains themselves suggested to inhibit nisin exchange by blood proteins. But...
