On April 7, 2014 Dr. Peter K. Liaw, Endowed Ivan Racheff Chair of Excellence in the Department of Materials Science and Engineering at The University of Tennessee, spoke about fatigue of bulk metallic glasses”.
A metallic glass is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Batches have been produced that demonstrate strengths much greater than conventional steel alloys. Predicting the fatigue life of such materials
is crucially important for their selection as structural materials. The materials are difficult to make in thick sections .
Peter K. Liaw obtained his Ph.D. in Materials Science and Engineering from Northwestern University. He has published over six hundred journal papers and edited more than sixteen books.
The April 14, 2014
speaker was Todd P. Witcher , Executive Director, Discover Life in America (DLIA). The All Taxa Biodiversity Inventory (ATBI) intends to catalog every living creature in Great Smoky Mountains National Park. There are 18,500 different species known in the Smokies and it is predicted that there are 60,000 to 80,000. There are 900 kinds of flies ( and more to come). A list of what has been found is on www DLIA.org.
ON April 21, 2014 Roy Arthur, Knox County Watershed Coordinator, Research Associate, described how for the past decade Knox County has implemented watershed initiatives in the Beaver Creek and Stock Creek watersheds to improve water quality in Knox County creeks and ultimately remove them from the State’s 303(d) list of impaired streams. They have worked with landowners in many small projects and work hard to get cooperation in improving water quality.
On April 28, 2014 the Technical Society speaker was Parci Gibson, National Pollutant Discharge Elimination System (NPDES) Project Manager.
She desribed the effects of the the new runoff reduction requirements
for site design standards as they relate to stormwater management. In the future the emphasis will be on putting stormwater into the soil rather than having it run off on the surface. There are Low Impact Best Management Practices that will be allowed under the new Runoff Reduction requirements.
As a project manager, Ms. Gibson works to ensure that Knox County remains compliant with all state and federal requirements as they relate to the Clean Water Act. In addition, Ms. Gibson creates all public engagement programs and materials for county employees as well as the general public to increase awareness of water quality issues and what people can do to reduce stormwater pollution.
