Intensification Of Clostridium Pasteurianum Fermentation Producing N-Butanol From Glycerol Using Microfiltration Cell Recycle, Colin W. Couper
Intensification Of Clostridium Pasteurianum Fermentation Producing N-Butanol From Glycerol Using Microfiltration Cell Recycle, Colin W. Couper
Electronic Thesis and Dissertation Repository
This work demonstrates lab scale intensification of the fermentation of glycerol to 1-butanol using Clostridum pasteurianum, starting with simulation and comparison of different cell recycle arrangements, development of a cell recycle apparatus with an existing bioreactor, and demonstration of fermentation with the final system. Fermentations performed with the completed system showed that the cell recycle system was not significantly inhibitory to fermentation, and achieved a maximum apparent cell dry weight of 3.14g/L and a maximum butanol productivity of 1.16g/Lh.

Using A Systems Approach To Analyze The Operational Safety Of Dams, Leanna M. King
Electronic Thesis and Dissertation Repository
Dam systems are arrangements of interacting components that store and convey water for beneficial purposes. Dam failures are associated with extreme consequences to human life, the environment and the economy. Existing techniques for dam safety analysis tend to focus on verifying system performance at the edge of the design envelope. In analyzing the events which occur within the design envelope, linear chain-of-events models are often used to analyze the potential outcomes for the system. These chain-of-events models require that combinations of conditions are identified at the outset of the analysis, which can be very cumbersome given the number of physically …
