Recovering Spirituality - What 1 Corinthians Really Says About Being Spiritual
Lecture given Tuesday, February 19, 2002, 9:45 AM at Abilene Christian University: "A careful reading of 1 Corinthians reveals Paul's prescription for a church that had spirituality all wrong. We will see that being spiritual has little to do with knowledge and self, and everything to do with community."

Computer Modeling of Flow, Thermal Condition and Ash Deposition in a Hot-Gas Filtration Device
The objective of the present study is to develop a computational model for simulating the gas flow, thermal condition and ash transport and deposition pattern in the hot-gas filtration systems. The computational model is to provide a virtual tool for design and operation modifications. Particular attention is given to the Particle Control Device (PCD) at the Power Systems Development Facility (PSDF) in Wilsonville, Alabama. For evaluation of gas velocity and temperature field in the vessel, the FLUENT commercial CFD computer code is used. Ash particle transport and deposition pattern was analyzed with the Lagrangian particle tracking approach.

Things Unseen: Three Key Questions for Churches of Christ in the New Millennium - Life: Can Churches of Christ Become Functionally Trinitarian?
Lecture given Tuesday, February 19, 2002, 8:30 AM at Abilene Christian University: "As the modern world recedes, Churches of Christ are finding their distinctive message and theology, which was rooted firmly in that world, less immediately convincing and more obviously deficient in the new cultural era we are entering. But this situation provides an opportunity to reclaim Christian truth that was compromised or even lost under the pressures and temptations of modernity. Three key questions focus this challenge for the church's heritage, life together and present message."

ANL/CRIEPI collaborative program for evaluation of irradiated EBR-II stainless steels.
The objective of this collaboration between Argonne National Laboratory (ANL) and the Central Research Institute of Electric Power Industry (CRIEPI) is to evaluate the effects of long-term, low-dose neutron exposure on the mechanical properties, dimensional stability, and associated microstructural changes of reactor structural materials. ANL believes that material data obtained from components irradiated in EBR-II provide valuable information that is useful for LWR plant life extension. CRIEPI is currently conducting research on many aspects of materials aging of LWR components including irradiation damage. Therefore, ANL and CRIEPI have decided to perform the following joint work, which is of interest to both laboratories and continues the collaborative relationship between the two labs. The program was initiated in February of 1999. Samples were taken from two separate subassemblies, designated S1951 and S1952. These subassemblies were constructed of 20% cold-worked Type 316 stainless steel. The samples from these subassemblies were irradiated at temperatures from 371-390 C to doses up to 56 dpa. The examinations in this program included: immersion density, microhardness, microstructure, and tensile properties. The material history, test plan, results of measurements, and discussion of results are included in this report.

FY02 CBNP Annual Report: Discovery of DNA Signature of Biothreat Detection Using Suppression Subtractive Hybridization
Our goal is to develop robust DNA signatures for rapid and specific DNA-based detection platforms that can be employed by CBNP to detect a wide range of potential agents. Our approach has resulted in highly specific DNA signatures for Yersina pestis, Bacillus anthracis and Brucella species. Furthermore, this approach can be applied to any genome (even uncharacterized ones), which facilitates DNA signature development for detection of newly emerging pathogens. We are using suppression subtractive hybridization (SSH) as a tool to define large DNA regions specific to multiple biothreat pathogens by comparing them to genomes of the most closely related organisms. This approach has become increasingly accurate as we continue to find new, distinctive strains and ever-closer near-neighbors. With the huge costs incurred by whole genome sequencing, it is not possible to sequence each new bacterial genome. However, it is completely practical to identify genome differences in the laboratory using SSH, and becomes especially useful when comparing new strains to previously sequenced genomes.

Development of Metallic Filters for Hot Gas Cleanup in Pressurized Fluidized Bed Combustion Applications
Alternative alloys derived from the wide array of aerospace superalloys will be developed for hot gas filtration to improve on both ceramic filters and ''first-generation'' iron aluminide metallic filter materials. New high performance metallic filters should offer the benefits of non-brittle mechanical behavior at all temperatures, including ambient temperature, and improved resistance to thermal fatigue compared to ceramic filter elements, thus improving filter reliability. A new powder processing approach also will be established that results in lightweight metallic filters with high permeability and weldability for enhanced capability for filter system manufacturing.

A Dynamically Adaptive Arbitrary Lagrangian-Eulerian Method for Hydrodynamics
A new method that combines staggered grid Arbitrary Lagrangian-Eulerian (ALE) techniques with structured local adaptive mesh refinement (AMR) has been developed for solution of the Euler equations. The novel components of the combined ALE-AMR method hinge upon the integration of traditional AMR techniques with both staggered grid Lagrangian operators as well as elliptic relaxation operators on moving, deforming mesh hierarchies. Numerical examples demonstrate the utility of the method in performing detailed three-dimensional shock-driven instability calculations.

Examinations of Chemical Resistance and Thermal Behaviour of Ceramic Filter Materials for Hot-Gas Cleaning
Increasing prosperity and the steady growth of the world population lead to a strongly rising energy requirement. Therefore the saving of the available resources as well as the limitation of CO{sub 2}-emission are the main reasons for developing highly efficient power stations. The use of combined cycle technology for advanced coal fired power plants allow a significantly higher conversion efficiency than it is possible in an only steam power plant. In order to increase the gas turbine inlet temperature, the filtration of fine particles is necessary. Therefore the filtration unit is one of the key components of the circulating pressurized fluidized bed combustion technology (PFBC). To use this technology more effectively, gas cleaning at high temperatures or in an reducing atmosphere is necessary. A possibility of the effective gas cleaning at high temperatures is the use of porous ceramic candle filters. The structure of such filter elements usually consists of a highly porous sup port which ensures the mechanical strength and a layer which operates as the functional part for the particle removal. To ensure a guaranteed lifetime of about 16000 h the effect of combustion or gasification atmosphere and temperature on the thermal and mechanical properties of the filter …

ASIC Wafer Test System for the ATLAS Semiconductor Tracker Front-End Chip
An ASIC wafer test system has been developed to provide comprehensive production screening of the ATLAS Semiconductor Tracker front-end chip (ABCD3T). The ABCD3T[1] features a 128-channel analog front-end, a digital pipeline, and communication circuitry, clocked at 40 MHz, which is the bunch crossing frequency at the LHC (Large Hadron Collider). The tester measures values and tolerance ranges of all critical IC parameters, including DC parameters, electronic noise, time resolution, clock levels and clock timing. The tester is controlled by an FPGA (ORCA3T) programmed to issue the input commands to the IC and to interpret the output data. This allows the high-speed wafer-level IC testing necessary to meet the production schedule. To characterize signal amplitudes and phase margins, the tester utilizes pin-driver, delay, and DAC chips, which control the amplitudes and delays of signals sent to the IC under test. Output signals from the IC under test go through window comparator chips to measure their levels. A probe card has been designed specifically to reduce pick-up noise that can affect the measurements. The system can operate at frequencies up to 100 MHz to study the speed limits of the digital circuitry before and after radiation damage. Testing requirements and design solutions …

Nuclear apoJ: A low dose radiation inducible regulator of cell death. Final report for period September 15, 1998 - September 14, 2001
This project was based on preliminary data that was published by Dr. Boothman (Yang et al. 2000) which indicated a strong induction of apoJ gene expression, increased secretion of the protein, and accumulation of an apparently somewhat different form of the apoJ protein in the nucleus of MCF-7 breast carcinoma cells undergoing response to DNA damage. A clone expressing apoJ protein was isolated that was capable of interacting with Ku80, a component of the double strand break repair complex that is essential for the successful repair of rearranging immunoglobulin and T-cell receptor genes as evidenced by failure to produce mature B and T cells in the absence of Ku70. ApoJ clones isolated and characterized by Dr. Boothman bound strongly to a Ku-70 ''bait'' protein. Over-expression of these same clones in a cell line was capable of killing the cell. ApoJ is very strongly induced in many instances of programmed cell death and has been proposed repeatedly to play some sort of effector role in the process. Our principle hypothesis for this study was that the strong induction of the apoJ gene and the particular expression of a nuclear form of the protein was potentially a causal factor in the decision …

Results of Tritium Tracking and Groundwater Monitoring at the Hanford Site 200 ARea State-Approved Land Disposal Site--Fiscal Year 2002
Tritium activities decreased in all three SALDS proximal wells during FY 2002, compared with FY 2001. Activities in well 699-48-77A first decreased to less than 3,000 pCi/L in January 2002, but rose to 150,000 in July, probably as a result of tritium discharges to SALDS that resumed in February 2002. Well 699-48-77C, where tritium analysis produced a maximum value of 750,000 pCi/L in January 2002, reflects the result of the delayed penetration of effluent deeper into the aquifer from tritium discharges. SALDS proximal well 699-48-77D produced a maximum result of 240,000 pCi/L in July 2002. Timing between detections of tritium and other constituents in well 699-48-77C suggest a delay of approximately three years from detection in wells 699-48-77A and 699-48-77D. Historically maxima for tritium (790 and 860 pCi/L in successive sample periods) suggest that tritium from SALDS may be reaching the northern edge of the 200 West Area, south of the facility.

Supernovae and neutrinos
A long-standing problem in supernova physics is how to measure the total energy and temperature of {nu}{sub {mu}}, {nu}{sub {tau}}, {bar {nu}}{sub {mu}}, and {bar {nu}}{sub {tau}}. While of the highest importance, this is very difficult because these flavors only have neutral-current detector interactions. We propose that neutrino-proton elastic scattering, {nu} + p {yields} {nu} + p, can be used for the detection of supernova neutrinos in scintillator detectors. It should be emphasized immediately that the dominant signal is on free protons. Though the proton recoil kinetic energy spectrum is soft, with T{sub p} {approx_equal} 2E{sub {nu}}{sup 2}/M{sub p}, and the scintillation light output from slow, heavily ionizing protons is quenched, the yield above a realistic threshold is nearly as large as that from {bar {nu}}{sub e} + p {yields} e{sup +} + n. In addition, the measured proton spectrum is related to the incident neutrino spectrum. The ability to detect this signal would give detectors like KamLAND and Borexino a crucial and unique role in the quest to detect supernova neutrinos.
