Stable isotopes of oxygen, carbon and nitrogen were used to understand the ecological changes induced by human activities. The existing method developed by McLaughlin et al. (2004) for determination of the oxygen isotopic composition of...
Carbon isotopes were used as tracers in the Florida Everglades to investigate the sources and sinks of dissolved organic carbon in natural and constructed wetlands and provide a way to monitor ecosystem restoration efforts. Stable carbon...
Gas phase mass spectral analysis is now showing great promise in the characterization of natural organic matter. With the routine availability of the soft electrospray ionization (ESI) technique, volatilization and ionization of a sample...
Exploring the Interaction of Personal and Contextual Factors during the Induction Period of Science Teachers and How This Interaction Shapes Their Enactment of Science Reform
The first years of teaching are demanding as the novice works to gain a degree of familiarity in her/his professional work. It is during this period that many teachers decide to leave the teaching profession or move away from the reform...
In the southernmost Appalachians, bimodal volcanics of Pumpkinvine Creek Formation (PCF) and its proposed equivalent, the Hillabee Greenstone (HG) have indistinguishable ages (~460 Ma) and trace element-REE pattern similar to an arc/back...
This dissertation presents the work of investigating methane emission and oxidation through landfill covers. Methane as a major source of greenhouse and is being emitted from solid waste landfill at a tremendous rates. These emissions...
