An Investigation Of Humeral Stress Fractures In Racing Thoroughbreds Using A 3d Finite Element Model In Conjunction With A Bone Remodeling Algorithm, Ryan James Moore

Master's Theses

The humerus of a racing horse Thoroughbred is highly susceptible to stress fractures at a characteristic location as a result of cyclic loading. The propensity of a Thoroughbred to exhibit humeral fracture has made equines useful models in the epidemiology of stress fractures. In this study, a racing Thoroughbred humerus was simulated during training using a 3D finite element model in conjunction with a bone remodeling algorithm. Nine muscle forces and two contact forces were applied to the 3-dimensional finite element model, which contains four separate load cases representing fore-stance, mid-stance, aft-stance, and standing. Four different training programs were incorporated …

Reflections Of College Students Promoting Engineering Through Biomechanical Outreach Activities Indicate Dual Benefits, Kimberly Edginton Bigelow

Mechanical and Aerospace Engineering Faculty Publications

Recent work by the National Academy of Engineering revealed that the public has a poor understanding of what engineers actually do on a day-to-day basis. This issue is compounded for non-traditional fields in engineering, such as biomechanical engineering. This is particularly problematic as such fields could draw interest from students not interested in traditional engineering careers, resulting in increased diversity.

To address this, mechanical engineering students taking an elective course, Biomechanical Engineering, were given an outreach assignment to teach at least one individual under the age of 18 about the field of biomechanical engineering through a hands-on activity. Students worked …

Nonequilibrium Thermodynamics Modeling Of Coupled Biochemical Cycles In Living Cells, Yaşar Demirel

Yaşar Demirel Publications

Living cells represent open, nonequilibrium, self organizing, and dissipative systems maintained with the continuous supply of outside and inside material, energy, and information flows. The energy in the form of adenosine triphosphate is utilized in biochemical cycles, transport processes, protein synthesis, reproduction, and performing other biological work. The processes in molecular and cellular biological systems are stochastic in nature with varying spatial and time scales, and bounded with conservation laws, kinetic laws, and thermodynamic constraints, which should be taken into account by any approach for modeling biological systems. In component biology, this review focuses on the modeling of enzyme kinetics …

Motion Of The Multisegmental Foot In Hallux Valgus, Karl Canseco, Leah Rankine, Jason T. Long, Thomas Smedberg, Richard Marks, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Hallux valgus is a common condition characterized by lateral deviation of the large toe and medial deviation of the first metatarsal. While some gait analyses of patients with hallux valgus have been performed using plantar pressures, very little is known about the kinematics of gait in this population. The purpose of this study was to evaluate triplanar kinematics in patients with hallux valgus using a multisegmental foot model. Materials and Methods: A 15-camera Vicon Motion Analysis System was used to evaluate the gait of 38 feet in 33 patients with mild to severe hallux valgus. The Milwaukee foot model was …
