Fate And Transport Of Microorganisms In Coastal Subsurface-Experiment And Modeling, Haibo Cao
Fate And Transport Of Microorganisms In Coastal Subsurface-Experiment And Modeling, Haibo Cao
LSU Doctoral Dissertations
The objective of this dissertation was to investigate the fate and transport of microorganisms in coastal subsurface. Two topics were studied: (1) evaluation of the performance of the Marshland Upwelling System (MUS) in removing fecal bacteria and the background recovery after it is shut down; (2) Investigation of the effects of salinity and soluble organic matter (SOM) on sorption of MS-2 and development of a model to describe the sorption and transport process. The MUS showed effective performance in removing fecal bacteria during its 32 month operation period at Bayou Segnette Site. The removal efficiency was increased with its operation …

Cluster Kinetics Modeling Of Glassforming Materials, Lisa Ann Brenskelle
LSU Doctoral Dissertations
In this work, a new model relating temperature and pressure to dielectric relaxation or viscosity of a glassformer is developed. The model is based upon cluster kinetics, reaction-like mechanisms describing interactions between glassformer monomers and their clusters. Mathematical solutions of population balance equations for monomer and cluster lead to molar concentrations in terms of rate coefficients of the reaction-like mechanisms. These are then related to viscosity or dielectric relaxation time through free volume theory. The resulting equations are tested against data for a variety of pure glassformers, fragile, non-fragile, large, and small molecules over a wide range of temperatures, pressures, …
