Angular dependence of the Josephson critical current across c-axis twist junctions of layered superconductors.
The authors studied theoretically the c-axis Josephson critical current for bicrystals of high temperature superconductors twisted an angle {phi}{sub 0} about the c-axis with respect to each other. They used the effective Lawrence-Doniach models appropriate for the cases of pure s-wave or d{sub x{sup 2}-y{sup 2}}-wave order parameters, and of a dominant d{sub x{sup 2}-y{sup 2}}-wave order parameter combined with a subdominant one of either s-wave or d{sub xy}-wave form, as a function of the temperature and {phi}{sub 0}. The results demonstrate that this new phase-sensitive experiment can serve as a very useful test of order parameter symmetry. In particular, the recent zero-field experiments in the vicinity of T{sub c} by li et al. on c-axis twist junctions of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} are very difficult to explain with a dominant d{sub x{sup 2}-y{sup 2}}-wave order parameter.

Application of Advanced Reservoir Characterization, Simulation, and Production Optimization Strategies to Maximize Recovery in Slope, and Basin Clastic Reservoirs, West Texas (Delaware Basin)
The objective of this Class 3 project is to demonstrate that detailed reservoir characterization of slope and basin clastic reservoirs in sandstones of the Delaware Mountain Group in the Delaware Basin of West Texas and New Mexico is a cost effective way to recover a higher percentage of the original oil in place through strategic placement of infill wells and geologically based field development. Project objectives are divided into two main phases. The original objectives of the reservoir-characterization phase of the project were (1) to provide a detailed understanding of the architecture and heterogeneity of two representative fields of the Delaware Mountain Group, Geraldine Ford and Ford West, which produce from the Bell Canyon and Cherry Canyon Formations, respectively, (2) to chose a demonstration area in one of the fields, and (3) to simulate a CO 2 flood in the demonstration area. The Bureau's industry partner for the initial Phase 1 of the project was Conoco, Inc.. After the reservoir characterization and simulation of an area at the northern end of the Ford Geraldine unit were completed, Conoco decided not to proceed to Phase 2, installation of a CO 2 flood in the demonstration area. This decision by Conoco provides …

Application of Reservoir Characterization and Advanced Technology to Improve Recovery and Economics in a Lower Quality Shallow Shelf San Andres Reservoir
The Class 2 Project at West Welch was designed to demonstrate the use of advanced technologies to enhance the economics of improved oil recovery (IOR) projects in lower quality Shallow Shelf Carbonate (SSC) reservoirs, resulting in recovery of additional oil that would otherwise be left in the reservoir at project abandonment. Accurate reservoir description is critical to the effective evaluation and efficient design of IOR projects in the heterogeneous SSC reservoirs. Therefore, the majority of Budget Period 1 was devoted to reservoir characterization. Technologies being demonstrated include: 1.Advanced petrophysics 2.Three-dimensional (3-D) seismic 3.Cross-well bore tomography 4.Advanced reservoir simulation 5.Carbon dioxide (CO2) stimulation treatments 6.Hydraulic fracturing design and monitoring 7.Mobility control agents

Compton Rejection for HPGe Detectors via Real-Time Pulse Shape Analysis
A Lawrence Livermore National Laboratory-developed pulse shape analysis (PSA) technique which performs real-time Compton suppression in High Purity Germanium (HPGe) detectors without the use of anti-coincidence detectors is described. Some preliminary measurements of a variety of sources with a standard HPGe detector system and our prototype PSA algorithm have been made and indicate that a reduction in Compton continuum can be achieved via PSA. These measurements represent an initial assessment of the effectiveness of the prototype PSA system for the improvement of spectral quality and future improvements are expected. Additional work is progressing to optimize the effectiveness of the algorithm for Compton rejection in standard HPGe detectors. Work is also progressing to extend the methodology to segmented HPGe detectors which could potentially yield significantly better Compton rejection and gamma-ray ima

Concrete Chemical Evolution
The objectives of this analysis are to discuss and evaluate testing results that were performed for the M&O by the Pennsylvania State University (PSU) to evaluate the potential long-term evolution of organic admixtures in cementitious materials at elevated temperatures. The testing was designed to help provide a basis for a determination by the Performance Assessment group (PA) of the long-term acceptability and longevity of cementitious materials for repository use. The main purpose of the testing was to assess the evolution of gases (especially CO{sub 2}) from hydrated cement paste at elevated temperatures and to determine the impact on alkalinity, i.e., the pH value of cement paste pore solution. This information in turn can be used as scoping information to determine if further tests of this nature are needed to support PA. As part of this discussion and evaluation of the PSU results, an assessment of alkalinity in a ''cementitious repository'' and an evaluation of organic materials are presented.

Electron-phonon coupling in {kappa}-(BEDT-TTF){sub 2}Cu(NCS){sub 2} organic superconductor studied by Raman scattering spectroscopy.
Low frequency Raman data for {kappa}-(ET){sub 2}Cu(NCS){sub 2}(T{sub c} = 10.4 K) are reported. Measurements have been performed in a wide range of temperatures (1.5-100 K) and frequency hardening related to the superconducting transition has been observed for all the low-lying coupled phonons. The measured relative frequency shifts are lower than those previously reported for {kappa}-(ET){sub 2}Cu[N(CN){sub 2}]Br (T{sub c} = 11.67 K), but the behavior of the two systems is similar and indicates a significant strength of the intermolecular electron-photon coupling. The effects of isotopic substitutions ({sup 13}C{sub 4} {sup 34}S{sub 8} and {sup 2}H{sub 8}) in ET molecules on the low frequency Raman active phonons of {kappa}-(ET{sub 2}Cu(NCS){sub 2}) are also reported. They give the first direct experimental confirmation to the suggested lattice softening induced by deuteration.

Final report for the Department of Energy funded cooperative agreement ''Electronic Research Demonstration Project'' [University electronic research administration demonstration project]
This is the final report for the Department of Energy (DOE) funded cooperative agreement ''Electronic Research Demonstration Project (DE-FC02-92ER35180)'' for the period August 1994-July 1998. The goal of the project, referred to as NewERA, was to demonstrate the use of open standards for electronic commerce to support research administration, otherwise referred to as Electronic Research Administration (ERA). The NewERA demonstration project provided a means to test interagency standards developed within the Federal Grant Electronic Commerce Committee, a group comprised of federal granting agencies. The NewERA program was initiated by DOE. NewERA was comprised of three separate, but related, ERA activities in preaward administration, postaward administration, and secure Internet commerce. The goal of New ERA was to demonstrate an open standard implementation of ERA using electronic data interchange, e-mail and Internet transaction security between grant applicants and DOE, along with t h e other participating agencies.

A geological approach to characterizing aquifer heterogeneity. Completion report, 1990--1994
Spatial variations of hydraulic conductivity have generally been recognized as the dominant medium-independent control on the transport and dispersion of contaminants in groundwater. Mathematical models that use statistical descriptions of the hydraulic conductivity spatial distribution are available to predict contaminant transport. Such models are expected to be major tools in dealing with contamination problems at DOE sites. Unfortunately, the statistical parameters needed for such models can usually only be obtained through geostatistical analysis of very large numbers of hydraulic conductivity measurements, with associated large costs and often-significant human risk at highly contaminated sites. More accurate and realistic conceptual models for the actual distribution of hydraulic conductivity, requiring fewer field data, would increase the reliability of contaminant transport predictions while decreasing their cost. The objectives of the project can therefore be summarized in the following question: How can the data requirements for geostatistical analysis of hydraulic parameters be reduced by incorporation of geological expertise and macroscopic proxy information into new mathematical models. Specifically, the authors proposed to combine intensive geological field observations with permeability measurements to discover relationships between sediment depositional processes, geological structures, and the geostatistics of the permeability distributions that result.

High-efficiency chlorine dioxide delignification. Summary of progress, April 1--June 30, 1998
The authors have been pursuing strategies for improving the efficiency of utilization and environmental performance of ClO{sub 2} in the delignification of kraft pulps. These strategies combine a pretreatment followed by ClO{sub 2} treatment under conditions selected to result in high efficiency, and a suitably altered alkaline extraction stage. In addition, a series of experiments was completed in which the authors compared the response to conventional D(EO) delignification of conventional kraft pulps and pulps from a laboratory simulation of Ahlstrom`s Lo-Solids{reg_sign} extended delignification (modified) process. These experiments were conducted over a range of kappa numbers for both pulping processes, and at high and low kappa factors. The results showed that the modified pulps were slightly easier to bleach in the conventional process, an observation which parallels the corresponding observation made earlier, when the same pulps were bleached with the Rapid D{sub 0} short-retention process. In other experiments, two sets of hardwood pulps of varied unbleached kappa number were subjected to determinations of their hexeneuronic acid contents. Pulps representing both conventional batch and extended (RDH) kraft pulping processes were included. Residual lignin and effluent structural analyses by NMR and gel permeation chromatography are continuing to generate data for the development of …

Integrated operations of the National Ignition Facility (NIF) optical pulse generation development system
We describe the Optical Pulse Generation (OPG) testbed, which is the integration of the MOR and Preamplifier Development Laboratories. We use this OPG testbed to develop and demonstrate the overall capabilites of the NIF laser system front end. We will present the measured energy and power output, temporal and spatial pulse shaping capability, FM bandwidth and dispersion for beam smoothing, and measurements of the pulse-to-pulse power variation of the OPG system and compare these results with the required system performance specifications. We will discuss the models that are used to predict the system performance and how the OPG output requirements flowdown to the subordinate subsystems within the OPG system.
