Bacterial Motility And Its Role In Biofilm Formation, Clayton J. Culp, Arezoo M. Ardekani, Adib Ahmadzadegan Aug 2017

Bacterial Motility And Its Role In Biofilm Formation, Clayton J. Culp, Arezoo M. Ardekani, Adib Ahmadzadegan

The Summer Undergraduate Research Fellowship (SURF) Symposium

Bacterial biofilms are known to cause millions of dollars in damage in the medical industry per year via infection of central venous catheters, urinary catheters, and mechanical heart valves. Unfortunately, there are some characteristics of biofilm formation that are yet to be fully understood. Recently much work has been done to investigate the motility characteristics of bacteria with hopes of better understanding the phenomena of biofilm formation. Still, one of the least understood stages is bacterial attachment or adhesion, a process designed to anchor bacteria in an advantageous environment. Providing a better understanding of bacterial motility near solid interfaces will …


An Electrochemical Analysis Of Fretting Corrosion In Metal-On-Metal Hip Implants Subjected To High Impaction Loads, Joe Morin, Timothy L. Norman, Thomas K. Fehring Apr 2017

An Electrochemical Analysis Of Fretting Corrosion In Metal-On-Metal Hip Implants Subjected To High Impaction Loads, Joe Morin, Timothy L. Norman, Thomas K. Fehring

The Research and Scholarship Symposium (2013-2019)

The metal-on-metal total hip arthroplasty, a procedure where the hip joint is replaced by a femoral prosthesis with a metal femoral head and a metal socket, has been a popular option for patients requiring a hip joint replacement. Metal on metal hip implants have been a successful implant design until recently where there has been an increased number of failures of this type of implant due to fretting corrosion, believed to be caused from the use of large femoral heads. Fretting corrosion in hip implants results from cyclic micromotion at the taper-trunnion interface; this interface motion removes the protective oxidation …


3d Printing Of Biodegradable Scaffolds For Tissue Engineering Applications, Joe Morin, Michael Pickett, Amy Abraham, Tiera Martinelli Apr 2017

3d Printing Of Biodegradable Scaffolds For Tissue Engineering Applications, Joe Morin, Michael Pickett, Amy Abraham, Tiera Martinelli

The Research and Scholarship Symposium (2013-2019)

With the recent improvements in three dimensional (3D) printing technologies, the potential for tissue engineering and regenerative medicine have significantly improved. One key idea in tissue engineering is to specifically design scaffolds to aid in the healing process by being incorporated into the body’s own tissue. The overall goal of this project is to investigate 3D printable scaffold design to access suitability for tissue replacement. This was accomplished by analyzing the effect of the material used to create the scaffolds, pore size, and pore shape on mechanical stiffness and cell culturability. Based on published literature, it was determined that, depending …


Soft-Tissue Artifact Compensation For Electromagnetic Motion Capture, George T. Dickinson, Steven K. Charles Feb 2017

Soft-Tissue Artifact Compensation For Electromagnetic Motion Capture, George T. Dickinson, Steven K. Charles

Biomedical Engineering Western Regional Conference

This purpose of this study is to develop a soft-tissue artifact compensation algorithm for the upper arm using electromagnetic motion capture systems that can be implemented in a wide range of applications. This study focuses on compensation of humeral axial rotation and forearm axial rotation.
