A force plate for measuring contact forces during dependent transfers onboard aircraft

Creator:: Schafer, Christopher A.
Abstract:: The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

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...

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...

Computational and experimental investigation of steady flow fields, turbulence, and hemodynamic wall stresses in patient-specific abdominal aortic aneurysm models

Creator:: Edgar, Erik S.
Abstract:: Steady flow fields and flow-induced wall stresses have been evaluated by experimental measurements and computational fluid dynamics (CFD) analysis in a series of patient-specific abdominal aortic aneurysm (AAA) models, over a range of Reynolds numbers (Re) from 125 to 3000 (500 to 3000 for CFD). Experimental methods used particle image...

Heparin-regulated release of growth factors in vitro and angiogenic response in vivo to implanted hyaluronan hydrogels containing VEGF and bFGF

Creator:: Pike, Daniel B.
Abstract:: Biocompatible hydrogels composed of covalently crosslinked, chemically modified hyaluronan (HA), gelatin (Gtn), and heparin (Hp) were synthesized for controlled release of human vascular endothelial growth factor (VEGF) or basic fibroblast growth factor (bFGF). We hypothesized that inclusion of small quantities of heparin in these gels would result in regulated growth...

Lead(II) Extraction with Electrospun Spiropyran Functionalized PMMA Nanofibers

Creator:: Fuchs, Brian K.
Abstract:: A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...

Uptake and metabolism of the explosive RDX by the marine seaweeds Portieria hornemannii and Acrosiphonia coalita, and uptake of the explosive TNT by algal extracts of Portieria hornemannii

Creator:: Weber, Ryan A.
Abstract:: This study examines the interactions between explosive environmental contaminants and marine seaweeds. The scope of this thesis includes studies done on the explosive RDX with tissue cultures of marine seaweeds, as well as studies on the explosive TNT with seaweed extracts. The ability of two different marine species of macroalgae...

Immobilization of hen egg white lysozyme by the sole histidine residue to polystyrene beads through peptide spacers

Creator:: Wu, Yawen
Abstract:: Lysozyme is a natural antimicrobial agent that is effective against many food spoilage and pathogenic microorganisms by disintegrating their cell walls. Immobilization of lysozyme has attractive applications for use in the food industry: (1) The enzyme could be readily separated from treated foods and beverages and re-used while the foods...

Preliminary study on the effect of pH on the treatment of lead contaminated wastewaters with ozone

Creator:: Adolf, Ronald L.
Abstract:: Ozone was found to quickly reduce the concentration of lead in a prepared solution when the solution pH of said solution was greater than 7.0. When a solution having a pH of greater than 7.0 was filtered the concentration of lead was less than approximately 1.0 ppm. 1.0 ppm is...

Removal of cryoprotectant with the use of a microseparation device

Creator:: Lusianti, Ratih E.
Abstract:: Cryoprotectants (CPAs) such as glycerol and dimethyl sulfoxide (DMSO) are commonly used during cryopreservation of cell based therapeutics. Although these additives are beneficial during freezing, it is often desirable to remove them before infusion into a patient. Currently, the most common method for CPA removal is by centrifugation. This method...
