This dissertation is divided into two major chapters. The first chapter covers the geologyof the Encuentro deposit with emphasis in the intrusion sequence, vein mineral assemblages and distribution, and age of mineralization. The data used for this section includes field mapping, petrography, elemental analysis of biotite, and isotopic geochronology. The...
Wheat (Triticum aestivum) is an important crop worldwide, however, in recent years concerns have been raised regarding two health issues, celiac disease and gluten sensitivity, and their relationship to wheat consumption. This increase has led to questions regarding potential changes over time in the composition of gluten (glutenin and gliadin)...

Anthropogenic climate change is an escalating environmental and humanitarian emergency, but American public opinion varies on the issue, particularly in terms of whether climate change is natural or human caused. Belief that climate change is human caused has been shown to be critical in terms of support for policy action....
Anammox (anaerobic ammonium oxidation) bacteria are capable of providing low-cost nitrogen removal for numerous types of wastewaters. However, low growth rates cause long startup-times and inhibition by oxygen and metabolic substrates necessitate close process control to maintain performance. Incorporation of Simultaneous Anammox and Denitrification (SAD) into constructed wetlands could provide...
