Issues involved with non-characterized control of methanotrophic bacteria

Description: Methane-utilizing bacteria, methanotrophs, have application as biocatalysts in the commodity chemical production, waste treatment and environmental remediation industries. Methanotrophs have the ability to oxidize many chemical compounds into more desired products, such as the production of propylene oxide. Methanotrophs can also degrade toxic compounds such as trichloroethylene. However, there are many physical, chemical and biological problems associated with the continuous oxidation of chemi… more

Copyright Term Extension: Estimating the Economic Values

Description: This report considers proposals to extend the duration of copyrights by 20 years (as in H.R. 2589 and other bills) and related proposals to charge a fee to the owners in order to receive the extension. The method of analysis is economic rather than legal. The report reviews the basic economic principals involved in copyright law and gives rough estimates of the value of copyrights on books, music, and movies produced in the 1920s and 1930s — those that would be most immediately affected by an e… more

Edge plasma modeling of limiter surfaces in a Tokamak divertor configuration

Description: During the startup phase of a tokamak the plasma configuration may evolve from a limiter to a divertor configuration. Some of the particle and heat flux from the core will be deposited on material surfaces near the separatrix instead of the divertor plates. Examples of such surfaces include the center-post in most tokamaks, baffles near the x-point that create closed divertors, and outboard limiter surfaces. Two-dimensional edge plasma models for tokamak divertor configurations typically give d… more

Diagnostics for a 1.2 kA, 1 MeV electron induction injector

Description: We are constructing a 1.2-kA, 1-MeV, electron induction injector as part of the RTA program, a collaborative effort between LLNL and LBNL to develop relativistic klystrons for Two-Beam Accelerator applications. The RTA injector will also be used in the development of a high-gradient, low-emittance, electron source and beam diagnostics for the second axis of the Dual Axis Radiographic Hydrodynamic Test (DARHT) Facility. The electron source will be a 3.5``-diameter, thermionic, flat-surface, m-ty… more

Hydrothermal growth kinetics of Np(IV) oxide

Description: Toulouse, France All previous knowledge leading to this estimate is of NpO2(c) is indirect, based on thermodynamic cycles. The phase itself has heretofore not been observed as a precipitate from aqueous solution. Recent attempts (e.g., Nitsche et al., 1993; Efurd et al., 1996) to establish solubility controls on Np in oxidizing groundwaters (including J-13 groundwater) starting from high concentrations (i.e., supersaturation) have shown the formation of one or both of two Np(V) phases, NaNpO2CO… more

Analysis of separatrix plasma parameters using local and multi-machine databases

Description: The ITER divertor modeling and database expert groups have assembled a scalar database of the edge plasma parameters for existing diverted tokamak devices as a means of enabling scaling studies of the SOL plasma. Data exist from ASDEX, ASDEX-Upgrade, C-MOD, COMPASS-D, DIII-D, JET, JFT-2M, and JT-6OU. We describe the scaling of plasma parameters at the outer midplane obtained from examination of this multi-machine database in this paper. The plasma parameters at the outer rnidplane are used as a… more

Summary (Summary Talk at the Quarkonium Production in Nuclear Collisions Workshop).

Description: This summary is an attempt to overview the wealth of new results and ideas in quarkonium physics presented at the Seattle Workshop. The Workshop in Seattle has shown that the physics of heavy quarkonium continues to develop at a fast pace; moreover, we have every reason to believe that the next year, with RHIC turning on, will mark the beginning of the new exciting era in this field.

One- and Two-Dimensional Wave Fronts in Diffusive Systems With Discrete Sets of Nonlinear Sources

Description: The authors study the dynamics of on- and two-dimensional diffusion systems with sets of discrete nonlinear sources. They show that wave fronts propagating in such systems are pinned if the diffusion constant is below a critical value which corresponds to a saddle-node bifurcation of the dynamics. In two dimensions they find that the dissipation is enhanced and moving plain and circular fronts are stable with respect to any perturbations.

Polycrystal Simulations of Texture Evolution during Deformation Processing

Description: Some recent research on the hot deformation of aluminum alloys has indicated that at elevated temperatures, slip occurs on {110}<110> systems in addition to the usual {111}<110> systems active at lower temperatures. The effect of these additional slip systems on the texture evolution of aluminum single and polycrystals is studied using finite element simulations. The crystals are deformed in plane strain compression, and the constitutive response is modeled using crystal plasticity to track the… more

Predictability of Minimum Noise in Electron Transport Through a Disordered Semiconductor

Description: The authors present an inverse method for electron transport which allows one to minimize the value of shot noise for a given value of the conductance by optimizing the spatial structure of a disordered semiconductor region. The method is based on the Green's function approach which is usually applied to the direct transport problem. A specific experimentally realizable example of a two-dimensional disordered semiconductor is presented which demonstrates the method of minimization of shot noise… more

UO2 Corrosion in High Surface-Area-To-Volume Batch Experiments

Description: Unsaturated drip tests have been used to investigate the alteration of unirradiated UO{sub 2} and spent UO{sub 2} fuel in an unsaturated environment, such as may be expected in the proposed repository at Yucca Mountain. In these tests, simulated groundwater is periodically injected onto a sample at 90 C in a steel vessel. The solids react with the dripping groundwater and water condensed on surfaces to form a suite of U(VI) alteration phases. Solution chemistry is determined from leachate at th… more

Colombia: The Problem of Illegal Narcotics and U.S. - Colombian Relations

Description: The United States has long been concerned with Colombia as a major producer and trafficker of the illegal narcotics entering this country: first marijuana, then cocaine, and now also heroin. Colombia's drug trafficking business has been dominated by two cartels during the two decades in which cocaine trafficking became a major activity: first the Medellin cartel, which dominated during the 1980s and then the Cali cartel, which dominated during the early 1990s. With the arrests of the major Cali… more
