A PowerPoint presentation given as part of the 2005 Hydrogen Program Review, May 24, 2005, in Washington, D.C.

Uranium mill tailings sites provide access to uranium-contaminated groundwater at sites that are shallow and low hazard, making it possible to address the following scientific objectives: (1) Determine the dominant electron accepting processes at field sites with long-term metal/rad contamination; (2) Define the biogeochemical transformations that may be important to either natural or accelerated bioremediation under field conditions; and (3) Examine the potential for using biostimulation (electron donor addition) to accelerate reduction of U(VI) to U(IV) at the field scale.

The objectives of this project are to develop cost-effective, optimized materials for intermediate temperature SOFC interconnect and interconnect/electrode interface applications and identify and understand degradation processes in interconnects and at their interfaces with electrodes.

Presentation for the 2005 American Society for Information Science and Technology (ASIS&T) Annual Meeting. This presentation discusses an alternative approach to interoperability testing and the use of special diagnostic records in the context of Z39.50 and online library catalogs.

Presents an analysis of VRLA + ultracapacitor use as energy storage systems in mild hybrid vehicles.

Presentation for the 2005 University Scholars Day at the University of North Texas discussing research on the characteristics of blue elliptical galaxies. This presentation explores star-forming systems, blue galaxies, and the origin of ellipticals.

Presentation for the 2005 University Scholars Day at the University of North Texas. This presentation discusses research on the hybrid Arab and Hispanic culture in the United States, understanding the customs and traditions of the two separate cultures respectively, and how the two cultures blend together socially, culturally, and linguistically.

Plutonium contamination in the environment is generally low-level and may be present and transported in a range of forms (IV, V, VI). Current remediation strategies are costly, financially and in terms of increased exposure risk to people and the environment. In situ bacterial biostabilization is a promising alternative.
