FSI Methodology for Analyzing VIV on Subsea Pipeline Free Spans with Practical Boundary Conditions
The objective of this thesis is to develop a more realistic numerical model than current methodologies for free span stability of submarine pipelines based on fatigue analysis. A general assumption in performing vortex-induced vibration (VIV) analysis of pipeline free spans is that both ends of the …

Influence of organic matter on the sorption and bioavailability of 2,4,6-trichloro-(¹⁴C)-phenol
Hydrophobic organic contaminants released into the subsurface can become sorbed to the soil matrix. The sorbed compounds may slowly leach into the groundwater, providing a long-term source of contamination. Bioremediation has been cited as a potential clean-up strategy for residual organics in …
