Biochemistry and genetics of autotrophy in Methanococcus (open access)

Biochemistry and genetics of autotrophy in Methanococcus

The project investigated fundamental aspects of carbon metabolism and genetics in the methane-producing archaeon Methanococcus maripaludis. The project yielded 23 peer-reviewed publications and five reviews from 1997-2007. PDFs of the peer-reviewed publications are included in the next section. Some papers of special interest are listed below. The pathway of pyruvate biosynthesis was elucidated by a combination of biochemical and physiological studies. This work characterized the very oxygen sensitive pyruvate oxidoreductase and showed that the enzyme was irreversible under physiological conditions. Evidence for the flow of electrons from the energy coupling hydrogenase b (Ehb) was presented. These results were published in the following papers. Yang, Y.L., J.N. Gluska, and W.B.

Improvement plans for the RHIC/AGS on-line model environments (open access)

Improvement plans for the RHIC/AGS on-line model environments

The on-line models for Relativistic Ion Collider (RHIC) and the RHIC pre-injectors (the AGS and the AGS Booster) can be thought of as containing our best collective knowledge of these accelerators. As we improve these on-line models we are building the framework to have a sophisticated model-based controls system. Currently the RHIC on-line model is an integral part of the controls system, providing the interface for tune control, chromaticity control, and non-linear chromaticity control. What we discuss in this paper is our vision of the future of the on-line model environment for RHIC and the RHIC preinjectors. Although these on-line models are primarily used as Courant-Snyder parameter calculators using live machine settings, we envision expanding these environments to encompass many other problem domains.

Clean Coal Program Research Activities (open access)

Clean Coal Program Research Activities

Although remarkable progress has been made in developing technologies for the clean and efficient utilization of coal, the biggest challenge in the utilization of coal is still the protection of the environment. Specifically, electric utilities face increasingly stringent restriction on the emissions of NO{sub x} and SO{sub x}, new mercury emission standards, and mounting pressure for the mitigation of CO{sub 2} emissions, an environmental challenge that is greater than any they have previously faced. The Utah Clean Coal Program addressed issues related to innovations for existing power plants including retrofit technologies for carbon capture and sequestration (CCS) or green field plants with CCS. The Program focused on the following areas: simulation, mercury control, oxycoal combustion, gasification, sequestration, chemical looping combustion, materials investigations and student research experiences. The goal of this program was to begin to integrate the experimental and simulation activities and to partner with NETL researchers to integrate the Program's results with those at NETL, using simulation as the vehicle for integration and innovation. The investigators also committed to training students in coal utilization technology tuned to the environmental constraints that we face in the future; to this end the Program supported approximately 12 graduate students toward the completion …
