The objective of this project is to consider the enhanced recovery of petroleum from the Dundee Formation using horizontal wells. This report contains summaries of the following tasks: project management; reservoir characterization; database management; drilling; and technology transfer. Some of the highlights are: well and log data sets and production data sets for all 30 fields are now complete and are stored in the TerraSciences` database at WMU; tops have been picked on all formations in all wells; well location and formation tops data sets are also now complete; The GeoGraphix Exploration System (GES) software package was acquired this quarter and installed on a PC in the Subsurface Laboratory at MTU.

As the technology associated with the development of solid-state drivers for inertial fusion energy (IFE) has evolved, increased emphasis has been placed on the development of an efficient approach for managing the waste heat generated in the laser media. This paper addresses the technical issues associated with the gas cooling of large aperture slabs, where the laser beam propagates through the cooling fluid. It is shown that the major consequence of proper thermal management is the introduction of simple wedge, or beam steering, into the system. Achieving proper thermal management requires careful consideration of the geometry, cooling fluid characteristics, cooling flow characteristics, as well as the thermal/mechanical/optical characteristics of the laser media. Particularly important are the effects of cooling rate variation and turbulent scattering on the system optical performance. Helium is shown to have an overwhelming advantage with respect to turbulent scattering losses. To mitigate cooling rate variations, the authors introduce the concept of flow conditioning. Finally, optical path length variations across the aperture are calculated. A comparison of two laser materials (S-FAP and YAG) shows the benefit of a nearly a-thermal material on optical variations in the system.

This guide describes record series that pertain to epidemiologic and health-related studies at the Center for Epidemiologic Research (CER) of the Oak Ridge Institute for Science and Education (ORISE). These records document the health and safety monitoring of employees and contract employees of the Department of Energy (DOE) and its predecessor organizations, the Manhattan Engineer District (MED), the Atomic Energy Commission (AEC), and the Energy Research and Development Administration (ERDA). History Associates Incorporated (HAI) prepared this guide as part of DOE`s Epidemiologic Records Inventory Project. This introduction briefly describes the Epidemiologic Records Inventory Project, HAI`s role in the project, the history of the DOE and its epidemiologic research program, and the history of the Oak Ridge Reservation and the Oak Ridge Institute for Science and Education. It also furnishes information on the procedures that HAI sued to select, inventory, and describe pertinent records; the methodology used to produce the guide; the arrangement of the record series descriptions; the location of the records; and procedures for accessing records repositories.

The inevitable transition to parallel programming can be facilitated by appropriate tools, including languages and libraries. After describing the needs of applications developers, this paper presents three specific approaches aimed at development of efficient and reusable parallel software for irregular and dynamic-structured problems. A salient feature of all three approaches in their exploitation of concurrency within a processor. Benefits of individual approaches such as these can be leveraged by an interoperability environment which permits modules written using different approaches to co-exist in single applications.

This research continues the long term goals of promoting nuclear medicine applications by improving the scientific basis for tumor diagnosis, treatment and treatment follow-up based on the use of cyclotron produced radiotracers in oncology. This program fits into the nuclear medicine component of DOE`s mission, which is aimed at enhancing the beneficial applications of radiation, radionuclides, and stable isotopes in the diagnosis, study and treatment of human diseases. The grant includes 3 interactive components: Radiochemistry/Cyclotron; Pharmacology/Immunology; and Imaging Physics. An essential strategy is as follows: novel radionuclides and radiotracers developed in the Radiochemistry/Section under the DOE grant during the 1992--1995 will be employed in the Pharmacology/Immunology component in the period 1996--1999. Imaging Physics resolves relevant imaging related physics issues that arise during the experimentation that results. In addition to the basic research mission, this project also provides a basis for training of research scientists in radiochemistry, immunology, bioengineering and imaging physics.

Based on studies the authors have performed with several radiation sources such as pulsed nuclear reactors, they have been able to construct a physical picture and measure quantitative parameters necessary to model the radiation-induced losses expected for fused silica and fused quartz National Ignition Facility (NIF) target area. It is important to note that these surrogate radiation sources do not have identical temporal and spectral characteristics to NIF, therefore caution is in order since the results obtained to date must be extrapolated somewhat to predict NIF performance.
