The university was well represented at the 116th meeting of the Tennessee Academy of Science, held recently at Austin Peay State University.

Our professors presented four discussions at the event and a student presented one. They included:

• “Gas Diffusion in Polystyrene Foam: A Multi-scale Approach” by Chemical Engineering professors Joseph Biernacki and Donald Visco, along with two student authors, D.M. Kirby and P. Kannan

• “Evolution Visits Tennessee, 1873-1878” by History Professor George Webb

• “Analysis of Urban Sprawl In Cookeville, Tennessee, Using GIS Technology” by Geoscience major Brian O’Neil Whitworth

• “Effect of Land Use on Water Chemistry and Macroinvertebrates in Three Watersheds” by Biology Professor Bradford Cook, Chemistry Professor John Harwood and Earth Sciences Professor Peter Li, who worked and presented with instructors from Cookeville High School and Harvard University as well

• And “What Is the Title of This Talk?” by Peter Li, who also presided over the geology, geography and history of science series of presentations.

Two students made poster presentations in the geology and geography category. Mark Ziska presented “Waste Water Treatment Plant Site Analysis Along Cane Creek in Putnam County.” Whitworth presented “Analysis of Microcrack Density in Folded Quartz Arenite Near Keyser, West Virginia.”

Chemistry Professor Jeff Boles, Biology professors John Harris and J. Michael Redding, and History Professor George Webb are all members of the TAS Executive Committee, and Boles, Harris and Webb also serve in various positions of TAS standing committees.
