Development of Potential Remote Coal Mine Fire Response Measures: Use of Multiple Passive Source Tracers and Simulation of High Expansion Foam Flow in Simulated Gob Material
… changes in the fire. The application of multiple passive source tracers provides improved detail of complex ventilation interactions over an extended period of time. The first work in this thesis details the testing of the passive release rates for three Perfluorocarbon tracer compounds over a …

Development and Evaluation of a Permeation Plug Release Vessel (PPRV) for the Release of Perfluoromethylcyclohexane (PMCH) in Underground Mine Tracer Gas Studies
… over 30 years. As a result, the methods used to release, sample, and analyze SF6 are well accepted. Although improvements are still being made to enhance the analysis of this tracer, the overall technique remains largely the same. However, as the complexity and size of underground mine …

A nanostructured porous silicon based drug delivery device
… drug delivery device for the controlled release of therapeutic proteins and peptides, are described in this thesis. <br/><br/>The initial prototype microdevice design incorporates a porous polysilicon (PPSi) structure as a drug reservoir. Two alternative methods were investigated to …

Proteomic and genomic characterization of the influence of copper on Legionella pneumophila and the drinking water microbiome
… that can be present in drinking water due to passive release from copper pipes or intentionally dosed (e.g., copper-silver ionization systems) for microbial control. However, some L. pneumophila strains have recently been found to exhibit copper resistance, an adaptive process that is not …
