1,3-Propanediol Made From Fermentation-Derived Malonic Acid: Office of Industrial Technologies (OIT) Agriculture Project Fact Sheet

Description: 1,3-Propanediol is one of two ingredients used in producing polytrimethylene terephthalate (PTT), a polymer which can be used in polyester and nylon applications. Researchers are developing a process to ferment biomass feedstock to malonic acid using filamentous fungi and then catalytically convert malonic acid to 1,3-propanediol.

200 West Area Dust Mitigation Strategies

Description: Various strategies were developed for the purpose of mitigating respirable dust experienced at facilities in the southwest corner of the 200 West Area. These strategies focused on treatment of that portion of the dust source located within the 200 West Expansion Area. Strategies included direct shielding of the facilities via establishment of a poplar windbreak and installation of an artificial windscreen; soil stabilization via seeding of herbaceous plants, soil fixatives, straw crimping, stra… more

Accuracy of Projection Methods for the Incompressible Navier-Stokes Equations

Description: Numerous papers have appeared in the literature over the past thirty years discussing projection-type methods for solving the incompressible Navier-Stokes equations. A recurring difficulty encountered is the choice of boundary conditions for the intermediate or predicted velocity in order to obtain at least second order convergence. A further issue is the formula for the pressure correction at each timestep. A simple overview is presented here based on recently published results by Brown, Corte… more

Advanced Tokamak Scenarios for the FIRE Burning Plasma Experiment

Description: The advanced tokamak (AT) capability of the Fusion Ignition Research Experiment (FIRE) burning plasma experiment is examined with 0-D systems analysis, equilibrium and ideal-MHD stability, radio-frequency current-drive analysis, and full discharge dynamic simulations. These analyses have identified the required parameters for attractive burning advanced tokamak plasmas, and indicate that these are feasible with the present progress on existing experimental tokamaks.

Afghanistan: Current Issues and U.S. Policy Concerns

Description: The United States and its allies are helping Afghanistan emerge from more than 22 years of warfare, although substantial risk to Afghan stability remains. Before the U.S. military campaign against the orthodox Islamist Taliban movement began on October 7, 2001, Afghanistan had been mired in conflict since the Soviet invasion of Afghanistan in 1979. The defeat of the Taliban has enabled the United States and its coalition partners to send forces throughout Afghanistan to search for Taliban and A… more

Anode Materials for Rechargeable Li-Ion Batteries

Description: This is the annual progress report for the Grant DE-FG03-00ER15035. This research is on materials for anodes and cathodes in electrochemical cells. The work is a mix of electrochemical measurements and analysis of the materials by transmission electron microscopy and x-ray diffractometry. Our materials studies on electrode materials divide into electronic studies of the valence at and around Li atoms, and the crystal structures of these materials. We are addressing the basic questions of how th… more

Anode Materials for Rechargeable Li-Ion Batteries

Description: This research is on materials for anodes and cathodes in electrochemical cells. The work is a mix of electrochemical measurements and analysis of the materials by transmission electron microscopy and x-ray diffractometry. At present, our experimental work involves only materials for Li storage, but we have been writing papers from our previous work on hydrogen-storage materials.

Application of scaling properties of the Vlasov and the Fokker-Planck equations to improved macroparticle models

Description: Numerical simulations of cooling processes over minutes or hours of real time are usually carried out using direct solution of the Fokker-Planck equation. However, by using scaling rules derived from that equation, it is possible to use macroparticle representations of the beam distribution. Besides having applications for cooling alone, the macroparticle approach allows combining the cooling process with other dynamical processes which are represented by area-preserving maps. A time-scaling ru… more

Assessment of primary production and optical variability in shelf and slope waters near Cape Hatteras, North Carolina. Final project report

Description: In this project we determined primary production and optical variability in the shelf and slope waters off of Cape Hatteras, N.C. These processes were addressed in conjunction with other Ocean Margins Program investigators, during the Spring Transition period and during Summer. We found that there were significant differences in measured parameters between Spring and Summer, enabling us to develop seasonally specific carbon production and ecosystem models as well as seasonal and regional algori… more

Assessment of the Relevance of Displacement Based Design Methods/Criteria to Nuclear Plant Structures

Description: Revisions to the USNRC Regulatory Guides and Standard Review Plan Sections devoted to earthquake engineering practice are currently in process. The intent is to reflect changes in engineering practice that have evolved in the twenty years that have passed since those criteria were originally published. Additionally, field observations of the effects of the Northridge (1994) and Kobe (1995) earthquakes have inspired some reassessment in the technical community about certain aspects of design pra… more

Assisted Suicide and the Controlled Substances Act: Legal Issues Associated with the Proposed Pain Relief Promotion Act

Description: The Pain Relief Promotion Act, as proposed in the 106th Congress, provided that the Attorney General, in determining whether the registration of a doctor for the administration of controlled substances is in the public interest, should give no force and effect to state law authorizing or permitting assisted suicide or euthanasia. This language would appear to have been designed to abrogate the legal reasoning set forth by the Attorney General in a press release regarding the application of the … more

BAF(2) POST-DEPOSITION REACTION PROCESS FOR THICK YBCO FILMS.

Description: The basic processes of the so-called BaF{sub 2} process for the formation of YBa{sub 2}Cu{sub 3}O{sub 7}, YBCO, films as well as its advantages over the in situ formation processes are discussed in the previous chapter. The process and the properties of YBCO films by this process were also nicely described in earlier articles by R. Feenstra, et al. Here, we will discuss two pertinent subjects related to fabrication of technologically viable YBCO conductors using this process. These are (1) the … more

BBU and Corkscrew Growth Predictions for the DARHT Second Axis Accelerator

Description: The second axis accelerator of the Dual Axis Radiographic Hydrodynamic Test (DARHT-II) facility will produce a 2-kA, 20-MeV, 2-{micro}s output electron beam with a design goal of less than 1000 {pi} mm-mrad normalized transverse emittance. In order to meet this goal, both the beam breakup instability (BBU) and transverse ''corkscrew'' motion (due to chromatic phase advance) must be limited in growth. Using data from recent experimental measurements of the transverse impedance of actual DARHT-II… more

Beam-Beam Compensation in Tevatron: Status Report

Description: The project of beam-beam compensation (BBC) in the Tevatron using electron beams [1] has passed a successful first step in experimental studies. The first Tevatron electron lens (TEL) has been installed in the Tevatron, commissioned, and demonstrated the theoretically predicted shift of betatron frequencies of a high energy proton beam due to a high current low energy electron beam. After the first series of studies in March-April 2001 (total of 7 shifts), we achieved tuneshifts of 980 GeV prot… more
