Development of a Coal Quality Expert
Task 3 provides detailed characterization of fuel properties of the test coals and in-depth evaluation of their performance characteristics under controlled pilot-scale combustion testing. Results from this task provide fundamental information required to develop some of the improved algorithms for the CQE. Both bench-scale fuel characterization and test furnace performance evaluations are being performed under this task. All pilot-scale combustion tests under this task have been completed. Topical reports for the coals evaluated under the Public Service Oklahoma's Northeastern Unit 4 and Northern States Power's King Unit 1 test series have been issued. Work continued during the past quarter on preparation of the final report for the Mississippi Power Company's Watson Unit 4 tests (to be completed first quarter 1993) and analyzing pilot-scale combustion data from the Alabama Power Company's Gaston tests; a topical report for the Gaston study will also be issued in 1993. Bench-scale testing and data analyses continued in support of the development of the slagging and fouling models. Data obtained from the analysis of samples of deposits, inflame solids, fly ash, and coal from CQE pilot-scale and drop tube combustion tests were evaluated for use in devising and verifying the slagging and fouling algorithms.

Moored Instrument for Time Series Studies of Primary Production and Other Microbial Rate Processes
The goal of this project is to build and test a Time Series Submersible Incubation Device (TS-SID) capable of the autonomous in situ measurement of phytoplankton production and other rate processes for a period of up at least three months. The instrument is conceptually based on a recently constructed Submersible Incubation Device (SID). The TS-SID is to possess the ability to periodically incubate samples in the presence of an appropriate tracer, and to store 94 chemically fixed subsamples for later analysis. The TS-SID has been designed to accurately simulate the natural environment, and to avoid trace metal contamination and physical damage to cells. Devices for biofouling control of internal and external surfaces are to be incorporated into the instrument. After the time series capabilities of the instrument have been successfully evaluated by medium-term coastal time series studies (up to one month), longer-term coastal time series studies (2-3 months) will be conducted to evaluate the biofouling prevention measures that have been used with the instrument.

Fundamental mechanisms in flue gas conditioning
We performed a wide variety of laboratory analyses during the past quarter. As with most of the work we performed during the previous quarter, our recent efforts were primarily directed toward the determination of the effects of adsorbed water on the cohesivity and tensile strength of powders. We also continued our analyses of dust cake ashes that have had the soluble compounds leached from their particle surfaces by repeated washings with water. Our analyses of leached and unleached dust cake ashes continued to provide some interesting insights into effects that compounds adsorbed on surfaces of ash particles can have on bulk ash behavior. As suggested by our literature review, our data indicate that water adsorption depends on particle morphology and on surface chemistry. Our measurements of tensile strength show, that for many of the samples we have analyzed a relative minimum in tensile strength exists for samples conditioned and tested at about 30% relative humidity. In our examinations of the effects of water conditioning on sample cohesivity, we determined that in the absence of absorption of water into the interior of the particles, cohesivity usually increases sharply when environments having relative humidities above 75% are used to condition and test …

SPECT assay of radiolabeled monoclonal antibodies. Progress report, September 1, 1992--August 24, 1993
The overall goal of this project is to improve the effectiveness of single photon emission computed tomography (SPECT) to image and quantify radiolabeled monoclonal antibodies. During the past year, we have made significant progress toward this goal, and this report summarizes that work. Our efforts have been mainly directed along three fronts. First, we have developed and tested new reconstruction methods including three-dimensional iterative algorithms that model non-uniform attenuation and distance-dependent detector response. Both fan beam and parallel beam collimator geometries have been modeled and novel ways of improving the efficiency of the computationally intensive methods have been introduced. Second, an ultra-high resolution, small field-of-view pinhole collimator has been constructed and evaluated. Reconstructed spatial resolution of 1 to 3 mm (FWHM) has been achieved in phantom scans with a useful field-of-view of 9 to 10 cm. Finally, we have investigated the ability of SPECT to image and quantify astatine-211 distributions. Reconstructed images of phantom data demonstrated quantitative accuracy to within 10% with proper attenuation and scatter compensation.

The {eta}{sub 6} at LEP and TRISTAN
The {eta}{sub 6} is a {open_quotes}heavy axion{close_quotes} remnant of dynamical electroweak symmetry breaking by a color sextet quark condensate. Electroweak scale color instanton interactions allow it to be both very massive and yet be responsible for Strong CP conservation in the color triplet quark sector. It may have been seen at LEP via its two-photon decay mode and at TRISTAN via its hadronic decay modes.

High SO{sub 2} removal efficiency testing. Technical progress report, [October 1--December 31, 1992]
Baseline testing at the ``base`` site. Tampa Electric Company`s (TECo`s) Big Bend Station, commenced on September 28 and was completed on October 2. Initial results from this testing were presented in the previous Technical Progress Report, but a more complete discussion is provided in this report. Parametric testing was conducted at the Big Bend site during this quarter to evaluate the effects of dibasic acid (DBA) addition on system SO{sub 2} removal performance. The parametric tests were conducted from November 2 through 19. A DBA consumption rate test was also conducted, after the parametric tests were completed. The DBA consumption test was conducted from November 21 through 25. Options I and II to the base program were exercised by DOE/PETC at the end of the previous quarter. These options involve testing at Hoosier Energy Rural Electric Cooperative Inc.`s Merom Station and Southwestern Electric Power Company`s Pirkey Station, respectively. Testing was conducted at Merom Station during November. Previously, Radian Corporation was the test contractor for EPRI-funded performance additive testing at this site. This EPRI-funded testing involved the equivalent of baseline testing, parametric testing with both DBA and sodium formate performance additives, and an additive consumption test with the DBA additive.
