Panelist Presentations & Q&A

Immediately following lunch, our women panelists will speak about the mathematics courses they took and the role mathematics plays in their chosen career, followed by questions from the audience.

Computational and Biochemical Approaches to Molecular Epidemiology

Mining activity in Butte, Montana has taken place, or continues to take place, within the urban residence of Butte itself. This has led to urban areas with high concentrations of toxic metals such as arsenic, lead, copper, zinc, mercury and cadmium. Advances in protein study and gene sequencing has opened the possibility of finding molecular biomarkers whose presence, absence or morphological changes could indicate disease processes in populations exposed to environmental toxins. While in principle, biomarkers can be any chemicals or metabolites, as well as proteins and genes that are indicative of exposure to xenobiotics, this study seeks to identify changes in cellular pathways that suggest chronic (or acute) exposure to low-levels of metals associated with historical mining activities on the Butte Hill that could cause oxidative stress or other stress to the cell.

Organic Wastewater Chemicals in Silver Bow Creek - Butte to Warm Springs Ponds

The purpose of this study is to detail and analyze the distribution, concentration, and loads of 5 organic compounds along Silver Bow Creek in Butte, Montana from the Municipal Wastewater treatment plant to the Warm Springs Ponds. The chemicals analyzed include Carbamazepine (pharmaceutical), Miconazole (fungicide) and three antibiotics – Sulfamethoxazole, Thiabendazole, and Ciprofloxacin. This project begins a 2 year study to analyze 6 additional compounds (11 compounds total), to develop an effective method to detail and analyze OWCs using Mass Spectrometer/Liquid chromatography system, and to aid in assessment of aquatic health and ongoing restoration work. The EPA method 1694 was used for analysis

Thermodynamic Analysis of Rare Earth Chlorination and Bromination Processes

Research funded by the Army Research Laboratory (ARL), the Metallurgical and Materials Engineering Department at Montana Tech investigated various methods of extracting and refining rare earth elements (REEs) from mineral ores and concentrates. Extensive thermodynamic, thermogravimetric and differential thermal analyses were performed to evaluate the relative stabilities of various REE compounds in order to assess potential methods for selective separation and recovery of specific REEs. Conversion of rare earth oxides (REO) to rare earth chlorides or bromides is a possible initial step in pyrometallurgical and hydrometallurgical processing of REEs. REO can be converted to chlorides or bromides by roasting in the presence of a chloridizing or bromidizing reactant. (e.g. NH4Cl and NH4Br).
