Techno-Economic Implications Of Fed-Batch Enzymatic Hydrolysis, Ellen Emanuel

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

As ethanol production continues to increase in the United States, cellulosic ethanol continues to gain traction as a viable option for meeting ethanol demands. In this work, a literature review of techno-economic analyses for cellulosic ethanol was conducted. It was found that pretreatment methods greatly affect the ethanol production costs. There is a lack of techno-economic data comparing a batch enzymatic hydrolysis to a fed-batch enzymatic hydrolysis for a separate hydrolysis and fermentation production process. Consequently, a techno-economic analysis comparing cellulosic ethanol production using batch versus fed-batch enzymatic hydrolysis was conducted.

Development Of Cardiac Atrial Kick Shear Wave Elastography To Assess Myocardial Stiffness, Aaron J. Engel

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Increased myocardial stiffness, which is characteristic of many cardiovascular diseases, leads to a loss of diastolic function and is a cause of diastolic heart failure. Current methods to estimate myocardial stiffness rely on pressure-volume relationships derived from invasive cardiac catheter measurements. Noninvasive methods to estimate myocardial stiffness include ultrasound-based and magnetic resonance-based shear wave elastography, where the stiffness of the tissue is related to the propagation speed of a shear wave. Currently, ultrasound-based cardiac shear wave elastography includes acoustic radiation force based methods; however, the in vivo generation and detection of the shear waves in myocardium is significantly degraded due …
