Concurrent resolution introduced by the Texas House of Representatives and Senate relating to congratulating the city of Spur, Texas, on its historic past and bright future.

On January 25, and 26, 2007, an NWChem meeting was held that was attended by 65 scientists from 29 institutions including 22 universities and 5 national laboratories. The goals of the meeting were to look at major scientific challenges that could be addressed by computational modeling in environmental molecular sciences, and to identify the associated capability development needs. In addition, insights were sought into petascale computing developments in computational chemistry. During the meeting common themes were identified that will drive the need for the development of new or improved capabilities in NWChem. Crucial areas of development that the developer's team will be focusing on are (1) modeling of dynamics and kinetics in chemical transformations, (2) modeling of chemistry at interfaces and in the condensed phase, and (3) spanning longer time scales in biological processes modeled with molecular dynamics. Various computational chemistry methodologies were discussed during the meeting, which will provide the basis for the capability developments in the near or long term future of NWChem.

The remediation of subsurface contaminants is a critical problem for the Department of Energy, other government agencies, and our nation. Severe contamination of soil and groundwater exists at several DOE sites due to various methods of intentional and unintentional release. Given the difficulties involved in conventional removal or separation processes, it is vital to develop methods to transform contaminants and contaminated earth/water to reduce risks to human health and the environment. Transformation of the contaminants themselves may involve conversion to other immobile species that do not migrate into well water or surface waters, as is proposed for metals and radionuclides; or degradation to harmless molecules, as is desired for organic contaminants. Transformation of contaminated earth (as opposed to the contaminants themselves) may entail reductions in volume or release of bound contaminants for remediation. Research at Rensselaer focused on the development of haloalkane dehalogenase as a critical enzyme in the dehalogenation of contaminated materials (ultimately trichloroethylene and related pollutants). A combination of bioinformatic investigation and experimental work was performed. The bioinformatics was focused on identifying a range of dehalogenase enzymes that could be obtained from the known proteomes of major microorganisms. This work identified several candidate enzymes that could be obtained …

This report provides information on groundwater monitoring at the Solid Waste Landfill during the quarterly time period July to September 2006. Conditions remain very similar to those reported in the previous quarterly report. Six background threshold values, one WAC 173-200 Groundwater Quality Criterion, and one WAC 246-290-310 Maximum Contaminant Level were exceeded. The results that exceed applicable limits are consistent with the type of waste disposed to the landfill including sewage and chlorinated hydrocarbons from either the sewage or the 1100 Area heavy equipment garage and bus shop.

We present measurements of elliptic flow and event-by-event fluctuations established by the PHOBOS experiment. Elliptic flow scaled by participant eccentricity is found to be similar for both systems when collisions with the same number of participants or the same particle area density are compared. The agreement of elliptic flow between Au+Au and Cu+Cu collisions provides evidence that the matter is created in the initial stage of relativistic heavy ion collisions with transverse granularity similar to that of the participant nucleons. The event-by-event fluctuation results reveal that the initial collision geometry is translated into the final state azimuthal particle distribution, leading to an event-by-event proportionality between the observed elliptic flow and initial eccentricity.
