This summary presents the data accumulated to date with only brief comment. It is prepared with the intent that the viewers will offer advice on terminology, data presentation, methods and other. The year end analysis will detail changes in the data due to the tillage treatments. The data is incomplete due to equipment problems and time limitations due to the wet fall and early freeze up. The trial was not completed due to our inability to get the Mikkelsen Chisel Plow Shovel (MCP), a 16 inch sweep with an anhydrous knife, to penetrate untilled land. The MCP shovel penetrated to deep on plowed ground and pulled so hard that the front wheels of our JD4440 tractor were jerked off the ground. The Standard Chisel Plow Shovels (SCP), a 16 inch sweep, worked well and the data is included.

In this project we well evaluate the performance of Sel-Gel alumina membranes in coal liquid upgrading processes under realistic temperature and pressure conditions and investigate the feasibility of using such membranes in a membrane reactor based coal liquid upgrading process. In addition, the development of novel ceramic membranes with enhanced catalytic activity for coal-liquid upgrading applications, such as carbon-coated alumina membranes, will be also investigated.

The objective of this contract is to extend and optimize UOP's single-stage, slurry-catalyzed co-processing scheme. The particular emphasis is one evaluating alternative and disposable slurry-catalyst systems. During the current quarter, Lloydminster vacuum resid was processed without the presence of coal. The objective of this study was to evaluate the manner in which the resid is upgraded at high-severity conditions to help understand the function of the resid during co-processing. This report coves Bench-Scale Runs 30 to 34. In Runs 30 to 34, Lloydminster vacuum resid was processed without the presence of coal using a 0.05 wt % molybdenum-based catalyst at 465{degrees}C.

This current project is pilot-scale testing of NO{sub x} recycle. The objective is to provide further fundamental understanding and useful information for its implementation at the Niles station. A Babcock Wilcox's 6 million Btu/hr Small Boiler Simulator (SBS) has been chosen to perform the tests. The SBS is the same type of cyclone furnace as that at Niles and simulates a large cyclone unit very well. The project involves conducting a series of tests which include injecting NO, NO{sub 2}, N{sub 2}O, and simulated NO{sub x} recycle stream respectively. The work performed during this reporting period focused on the site preparation, shakedown tests, and baseline tests. The shakedown testing of NO injection into the primary air stream alone and the secondary air stream alone showed promising results. A large amount of NO injected into furnace was destroyed, especially when the NO was injected into the primary air duct. However, the measuring instrumentation needs to be improved to give accurate data.

The objective of this contract is to extend and optimize UOP's single-stage, slurry-catalyzed co-processing scheme. The current task is to complete a long-term operability run using a 0.05 wt-% Mo-based catalyst at approximately 460{degrees}C. The objectives of this run are to demonstrate that high-severity conditions can be run for an extended period of time (at least one month) and to collect enough product sample to do a complete Hempel fractionation and detailed characterization of the individual naphtha, distillate, and VGO cuts. This information will be used to reevaluate the engineering design and product upgrading scheme that was developed under the first co-processing contract (DE-AC22-84PC70002). During the current two quarters, the long-term operability study was unsuccessfully attempted several times. This report discusses these attempts.

Conformal field theories comprise a vast class of exactly solvable two dimensional quantum field theories. Conformal theories with an enlarged symmetry group, the current algebra symmetry, axe a key ingredient to possible string compactification models. The following work explores a Lagrangian approach to these theories. In the first part of this thesis, a large class of conformal theories, the so-called coset models, are derived semi-classically from a gauged version Of the Wess-Zumino-Witten functional. A non-local field transformation to the parafermionic field description is employed in the quantization procedure. Classically, these parafermionic fields satisfy non-trivial Poisson brackets, providing insight into the fractional spin nature of the conformal theory. The W-algebra symmetry is shown to appear naturally in this approach. In the second part of this thesis, the connection between the fusion algebra structure of Wess-Zumino-Witten models and the quantization of the Chern-Simons action on the torus is made explicit. The modular properties of the conformal model are also derived in this context, giving a natural demonstration of the Verlinde conjecture. The effects of background gauge fields and monopoles are also discussed.

I put forward a two-Higgs-doublet model in which CP violation is mediated only by the neutral Higgs bosons, via the mechanism of scalar-pseudoscalar mixing. In this model there is no CP violation in the exchange of either W bosons or of charged Higgs bosons. The model is therefore an approximate realization of the superweak theory of CP violation. It has only two basic CP-violating quantities. I point out that other models of this kind, but with more than two Higgs doublets, may also be built.

At the request of the Brookhaven National Laboratory Office of Environmental Restoration, and with the cooperation of the Safety and Environmental Protection and Plant Engineering Divisions, a Geographic Information System (GIS) Task Group has undertaken an effort to identify the data requirements, potential applications, and computing environment within which an integrated GIS could be implemented to meet the environmental and facilities management needs of the Laboratory. The Task Group held discussions with the three participating groups and with Laboratory officials. Software and hardware vendors were invited to demonstrate their products to all participants using BNL data, and private consultants discussed their GIS and database applications. After considering the needs of the three groups and other general implementation concerns, a list of ten requirements for a BNL site-wide GIS has been determined. On the basis of these considerations, three conceptual models for an integrated GIS are defined. These include a highly centralized system, a fully distributed system, and a composite model. The models differ in their allocation of responsibility for data management, applications development and GIS analysis, and local user support. Several issues remain to be resolved before an integrated GIS for the three operational groups can be fully implemented.

The Safety Analysis and Engineering Services Group has performed a survey of the Savannah River Technology Center (SRTC) technical capabilities, skills, and experience in Decontamination and Decommissioning (D&D) activities. The goal of this survey is to enhance the integration of the SRTC capabilities with the technical needs of the Environmental Restoration Department D&D program and the DOE Office of Technology Development through the Integrated Demonstration Program. This survey has identified technical capabilities, skills, and experience in the following D&D areas: Characterization, Decontamination, Dismantlement, Material Disposal, Remote Systems, and support on Safety Technology for D&D. This review demonstrates the depth and wealth of technical capability resident in the SRTC in relation to these activities, and the unique qualifications of the SRTC to supply technical support in the area of DOE facility D&D. Additional details on specific technologies and applications to D&D will be made available on request.

Using the example of the helical wiggler proposed for the KEK photon factory, we show how to integrate the equation of motion through the wiggler. The integration is performed in cartesian coordinates. For the usual expanded Hamiltonian (without square root), we derive a first order symplectic integrator for the purpose of tracking through a wiggler in a ring. We also show how to include classical radiation for the computation of the damping decrement.

This report discusses documentation of sample quality and deterioration. Various tasks covered under this heading include: collection of samples, sampling handling and processing; characterization of coal samples; distribution of samples to users; operation of the DOE coal data base. (VC)

Coal-water slurries have the potential of a near term replacement for fuel oil. In order to gain the fundamental understanding of the preparation and handling of coal-water slurries, experiments were performed to identify the relationship between the coal content of a given coal-water slurry and its physical and chemical properties. The objectives of this program were: Investigate the relationship between the chemical and physical properties of coal and the rheology of coal-water slurry Define procedures for evaluating and preparing coal water slurries for a particular coal candidate, based on the characteristic coal properties Develop improved methods of screening surfactants used in coal-water slurry preparation Perform experiments designed to investigate the effect of characteristic coal properties on slurry quality, by examining the effect of the individual coal properties on slurry quality Develop a statistical formulation to predict the coal content of a given coal water slurry content based on the coal characteristic properties.
