Corrosion Prevention And Control Training In An Immersive Virtual Learning Environment, Rustin Deane Webster
Corrosion Prevention And Control Training In An Immersive Virtual Learning Environment, Rustin Deane Webster
All ETDs from UAB
The majority of military education and training has not veered far from the days of chalk and talk instruction. Often with technological breakthroughs comes the proposal of the next revolution in multimedia instruction. Motion pictures to radios to educational television programs have all seemed to come and gone. The next wave of multimedia learning may involve more than a PowerPoint® presentation and lecture. Researchers continue to propose that Virtual Reality (VR) will find its true application and/or market in education and training. The objective of the project was to develop and provide a low-cost, scalable, and portable VR system containing …
Characterization Of Explanted Endovascular Stents: A Study Of In-Vivo Corrosion And The Role Of Vascular Calcification In Stent Fracture, Dina Halwani
All ETDs from UAB
The electrochemical and mechanical stability of endovascular stents in-vivo is essential for their biocompatibility. Limited information is available regarding the condition of stents following interaction with vascular tissue, as a result, twenty seven stented vessels containing 45 stents (33 bare metal and 12 drug eluting) were retrieved during autopsy and vascular surgery. The stent/tissue components were carefully separated using a rigorous tissue dissolution protocol. Stent surfaces were characterized using 3D digital optical and scanning electron microscopy. Transferred metallic elements in dissolved tissue were measured using mass spectroscopy. Histopathologic assessment of stented tissue, when available, was also performed. Fifteen out of …
