Corrective Action at Tiered-Permitted Hazardous Waste Facilities

Supervising Hazardous Substances Scientist
California Department of Toxic Substances Control
Tiered Permitting Corrective Action Branch, Cypress, CAAbstractCorrective action is the term used by federal and state law to refer to the process for cleanup at hazardous waste facilities. In California DTSC is the agency responsible to implement corrective action at facilities permitted under both state and federal law. DTSC is one of six boards, departments and offices that is part of the California Environmental Protection Agency.This presentation will briefly explain the corrective action process and provide some examples of how DTSC implements this process in the cleanup of hazardous waste facilities. This presentation will also explain how the results of the site investigation are used to develop a conceptual site model in preparation for development of a remedial action plan.Location: Kaprielian Hall (KAP) - rielian Hall, Room 156

Mihri OzkanAssociate Professor at the Department of Electrical Engineering
Center for Nanoscale Science and Engineering
University of California Riverside Importance of engineering at the nanoscale is more appreciated recently to cure diseases such as cancer or to fabricate devices at the scales off bacteria or virus with improved performance. In my talk, I will be giving number of examples from our recent studies specifically about imaging of nanotherapeutics, DNA sensors and bio-templated electronic devices such as resonant tunneling diode and memory. Firstly, label-free detection of nanoparticle therapeutics for in-vitro applications on human breast cancer cells will be demonstrated using a custom built hybrid AFM/NSOM platform. Different types of operational modes revealed the special placement of iron oxide nanoparticles on breast cancer cells after incubation at varying conditions. This study demonstrated label-free imaging of iron oxide particles and their uptake percentage based on their size and time of incubation. Secondly, multi-segmented nanowires in electrical sensor platform will be introduced with successful demonstrations of presence/absence of complementary DNA sequences inside the test buffer. Lastly, nanodevices synthesized using different bio-templates including DNA, PNA and viruses will be introduced. Electrical characterization of hybrid memory and negative differential resistance will be discussed on quantum dot/virus and SWNT/DNA or PNA hybrids, respectively. Short Biography: Dr. Mihri Ozkan is currently an Associate Professor in the Department of Electrical Engineering at UC-Riverside with a research focus in nanotechnology and its applications in biology and engineering. She received her Ph.D. degree in the Department of Electrical and Computer Engineering at UC-San Diego and her M.S. degree in the Department of Materials Science and Engineering at Stanford University. She has over four years of industrial experience including at Applied Materials, Analog Devices and at IBM Almaden Research Center. Dr. Ozkan is the recipient of number of awards including Army's Young Investigator Award (2006), Distinguished Engineering Educator of the Year Award by the National Engineers' Council (2006), Regents Faculty Excellence Award (2006, 2004, 2002), Emerging Scholar Award by the American Association of University Women (2005), Invited participant to the National Academy's Keck Future Initiatives Conference (2005), Visionary Science Award by the BioMEMS and Biomedical Nanotechnology Conference (2003),and "Achievement in Technical Ingenuity" Award by the Inland Empire Economic Partnership (2003). She is an active board member and treasurer in the International Society for BioMEMS and Biomedical Nanotechnology. Her editorial activities include the Journal of Sensors and Actuators B, the Journal of Biomedical Microdevices and the Springer Encyclopedia about BioMEMS and Nanotechnology. She holds more than 25 patent disclosures and about 8 US-patents.Date: Friday, January 26, 2007

SOME EXPERIMENTAL RESULTS ON ADIABATIC SHEAR BANDING

THE MORK FAMILY DEPARTMENT OF CHEMICAL ENGINEERING AND MATERIALS SCIENCEPRESENTS A SEMINAR
BYD. RittelFaculty of Mechanical Engineering Technion
32000 Haifa, IsraelSOME EXPERIMENTAL RESULTS ON ADIABATIC SHEAR BANDINGABSTRACT Assessing the dynamic mechanical properties of structural materials is an important stage of the design process of structures that must withstand various impacts. This data is mostly needed for numerical simulation purposes, when the dynamic response and eventual failure of a structure is to be evaluated. In this talk, we will address one specific dynamic failure mechanism, namely adiabatic shear banding. Adiabatic shear banding (ASB) is a catastrophic failure mechanism that may develop in certain ductile materials subjected to dynamic loading. The phenomenon itself consists of a narrow band of sheared material, in which the local temperature may reach a significant fraction of the melting temperature, as a result of thermomechanical coupling effects. As of today, there is an overwhelming disparity between analytical-numerical models related to ASB formation, and experimental evidence aimed at verifying a specific criterion or simply bringing physical evidence. This excludes of course the wealth of information related to microstructural aspects of ASB. The Dynamic Failure Laboratory at Technion has been investigating ASB formation from an experimental point of view. This talk will present new results on ASB formation in metals.
Three specific issues will be addressed, namely:1. A physical criterion for the onset of ASB formation
2. The influence of hydrostatic pressure on ASB formation
3. The influence of geometrical imperfections on ASB formationJanuary 26, 2006
