Development of core analysis procedures using x-ray computerized tomography. Quarterly report, September 1, 1988--November 30, 1988
In a letter from John C. Lorenz of Sandia National Laboratories dated November 8, 1988, analyses of interest included. With the core received, measurements are not possible. Core must be loaded into a passive vessel to flow various fluids for permeability measurements. Because the core was slabbed and plugged, this was not possible. Microfractures or porosity distribution can also be seen by flowing two fluids with contrasting attenuation coefficients and using a subtractive imaging technique. This again could not be done because core could not be inserted into a flow vessel. Similarly, fracture interconnections could not be measured. Each cross-sectional computerized tomography image is made up of a 256 {times} 256 array of data. This data array is composed of CT numbers which are collected from the scanner. These CT numbers are defined as normalized attenuation coefficients for the material being scanned. At the energy level used for this data, the CT numbers are approximately proportional to the density of the sample material. Subsequently, colors are, assigned arbitrarily to the CT numbers to highlight contrasts in density in the core. Red is assigned to higher-density regions and blue to lower density regions. Variations from red to blue are shown in …

A programming paradigm for distributed-memory computers
One of the problems that arises in programming a multicomputer is the effective partitioning of the work into tasks and the assigning of those tasks to the processors. We will present a programming paradigm as a method of structuring the algorithms, allowing us to identify and separate programming phases. This paradigm allows us to develop a general software tool for dynamically allocating work to the processors while hiding many details of load balancing. Our paradigm consists of four phases: partitioning the work, mapping the tasks into the processors connected by some virtual topology, running the application program, and embedding the virtual architecture into the actual machine. The paradigm applies to diverse problems and to a variety of multiprocessors without significant reprograming. We will use the multisection method for computing eigenvalues to show how this tool works.

The Hall-Petch relationship and mechanisms of fracture in B2 compounds. Third year progress report
A study was initiated in 1987 to examine structure and properties of grain boundaries in the B2 ordered alloys FeAl and NiAl. This project continued from 1990, with initial emphasis on CoAl, FeCo, and CuZn, but with continued work on FeAl and NiAl. Effect of alloy composition on structure/chemistry and properties of grain boundaries were examined by measuring yield strength vs grain size, measuring grain boundary composition using a scanning Auger electron microprobe, examining dislocation/grain boundary interactions during in-situ straining in TEM, and determining fracture modes and assessing strain extent at fracture surfaces using selected area channeling patterns. Progress during the last 3 years is reviewed.

Gun Ban for Persons Convicted of Misdemeanor Crime of Domestic Violence: Ex Post Facto Clause and Other Constitutional Issues
This report examines two new federal firearms offenses created by amendment of 18 U.S.C. 922(d) and (g). Section 922(d)(9) which makes it unlawful for any person knowingly to sell or otherwise dispose of any firearm or ammunition to a person convicted of a misdemeanor crime of domestic violence. The new law gives the domestic violence misdemeanant two new statutory defenses to the validity of the predicate conviction.

Reflector Technology Development and System Design for Concentrating Solar Power Technologies
Alcoa began this program in March of 2008 with the goal of developing and validating an advanced CSP trough design to lower the levelized cost of energy (LCOE) as compared to existing glass based, space-frame trough technology. In addition to showing a pathway to a significant LCOE reduction, Alcoa also desired to create US jobs to support the emerging CSP industry. Alcoa's objective during Phase I: Concept Feasibility was to provide the DOE with a design approach that demonstrates significant overall system cost savings without sacrificing performance. Phase I consisted of two major tasks; reflector surface development and system concept development. Two specific reflective surface technologies were investigated, silver metallized lamination, and thin film deposition both applied on an aluminum substrate. Alcoa prepared samples; performed test validation internally; and provided samples to the NREL for full-spectrum reflectivity measurements. The final objective was to report reflectivity at t = 0 and the latest durability results as of the completion of Phase 1. The target criteria for reflectance and durability were as follows: (1) initial (t = 0), hemispherical reflectance >93%, (2) initial spectral reflectance >90% for 25-mrad reading and >87% for 7-mrad reading, and (3) predicted 20 year durability of less …

Modification of toolmakers' microscope for use in an explosive environment
A large Leitz Universal Toolmakers' Microscope, Model UWM, was modified for use in an explosive environment defined by the National Electric Code as a rating of Class II, Group G. Use of the explosion-proof (EP) microscope provided a means for dimensionally measuring delicate pressed explosive material without contacting the material and subjecting it to possible contamination and mechanical destruction. Inexpensive design concepts, material, and hardware were used to effect the modifications of explosion-proofing. The accuracy, sensitivity, and repeatability of the Toolmakers' Microscope were not altered by the modification. (auth)

Coalbed Methane Procduced Water Treatment Using Gas Hydrate Formation at the Wellhead
Water associated with coalbed methane (CBM) production is a significant and costly process waste stream, and economic treatment and/or disposal of this water is often the key to successful and profitable CBM development. In the past decade, advances have been made in the treatment of CBM produced water. However, produced water generally must be transported in some fashion to a centralized treatment and/or disposal facility. The cost of transporting this water, whether through the development of a water distribution system or by truck, is often greater than the cost of treatment or disposal. To address this economic issue, BC Technologies (BCT), in collaboration with Oak Ridge National Laboratory (ORNL) and International Petroleum Environmental Consortium (IPEC), proposed developing a mechanical unit that could be used to treat CBM produced water by forming gas hydrates at the wellhead. This process involves creating a gas hydrate, washing it and then disassociating hydrate into water and gas molecules. The application of this technology results in three process streams: purified water, brine, and gas. The purified water can be discharged or reused for a variety of beneficial purposes and the smaller brine can be disposed of using conventional strategies. The overall objectives of this research …

Production of Actinium-225 via High Energy Proton Induced Spallation of Thorium-232
The science of cancer research is currently expanding its use of alpha particle emitting radioisotopes. Coupled with the discovery and proliferation of molecular species that seek out and attach to tumors, new therapy and diagnostics are being developed to enhance the treatment of cancer and other diseases. This latest technology is commonly referred to as Alpha Immunotherapy (AIT). Actinium-225/Bismuth-213 is a parent/daughter alpha-emitting radioisotope pair that is highly sought after because of the potential for treating numerous diseases and its ability to be chemically compatible with many known and widely used carrier molecules (such as monoclonal antibodies and proteins/peptides). Unfortunately, the worldwide supply of actinium-225 is limited to about 1,000mCi annually and most of that is currently spoken for, thus limiting the ability of this radioisotope pair to enter into research and subsequently clinical trials. The route proposed herein utilizes high energy protons to produce actinium-225 via spallation of a thorium-232 target. As part of previous R and D efforts carried out at Argonne National Laboratory recently in support of the proposed US FRIB facility, it was shown that a very effective production mechanism for actinium-225 is spallation of thorium-232 by high energy proton beams. The base-line simulation for the …

Analysis of OH Bolted Ear Connection
The D0 endcap calorimeter outer hadronic (OH) modules play a major structural role in the calorimeter assembly. The disrete modules, once connected together, form a ring within which other massive calorimetry will reside. It has been proposed that the connection of the OH at the downstream end be accomplished by extending the downstream endplates in the radial direction to form 'ears', and then through-bolting between adjacent ears as shown in Fig. 1. A single 2 1/4 in. dia. bolt is used, and previous calculations have determined that the design load on this joint should be 130,000 lbs tension. The high load and serious consequences of failure make this a critical component in the calorimeter assembly. The purpose of this analysis is to investigate the stresses in the connection and other mechanical characteristics which determine joint performance.

Acoustic flaw triangulation on a thin spherical shell: an analytical solution
An analytical solution for acoustic flaw triangulation on thin spherical shells has been prepared. A FORTRAN program is provided which takes as input the differences in the arrival times of acoustic energy at the transducers and evaluates the spherical coordinates of the flaw. Only three experimental time differences need be measured. For this measurement, four transducers are required. One transducer is placed at (R, 0, 0) in spherical coordinates; the other three are spaced 90 degrees apart around the equator.
