[Letter from Jack Davis and Bill McCarter to Chad Woolery, April 29, 1993]
Photocopy of a letter from Jack Davis and Bill McCarter, co-directors of North Texas Institute for Educators on the Visual Arts, to Char Woolery, Acting Superintendent for Dallas ISD. Davis and McCarter start the letter by congratulating Woolery on his new position as Acting Superintendent, giving him well wishes for the extremely important position. However, Davis and McCarter continue stating they are not thrilled with the principals participation in activities during the Summer Institutes. Stating that the leadership within the individual schools need an understanding of discipline-based art education and that they are planning a special day for administrators to construct the curriculum before any implementation can take place. Davis and McCarter have checked every district calendar in their consortium and determined that the administrator day would happen on June 8th, 1993, however, they regret to inform Woolery that Dallas principals will not be able to participate due to June 8th not being workable for them. Davis and McCarter then propose that they'd have another opportunity for the administrators specially for DISD in the fall. The letter ends with the promise of sending an invitation to the administrators of DISD at a later date.

Plant Closings, Mass Layoffs, and Worker Dislocations: Data Issues
For at least 15 years Members of Congress have continued to ask: How many U.S. manufacturing plants have closed? For at least 15 years they have continued to ask: How many U.S. manufacturing plants have relocated abroad, and where have they gone? For at least 15 years the answer has been: For the most part, those questions can't be answered, based on Government data. How many plants are moving to Mexico? What industries and what States are the plants from? How many U.S. workers are losing their jobs as a result? It appears that still, after two legislative attempts to mandate collection of these data, the Government publishes no counts of U.S. plant closings, and almost no information on plant relocations. Options for strengthening the data systems include addressing three main weaknesses: inadequate data program design, a plant closing definition that misses its mark, and publication of partial instead of complete survey results.

Measurements of the total CO[sub 2] concentration and partial pressure of CO[sub 2] in seawater during WOCE expeditions in the South Pacific Ocean
During the first year of the grant, we participated in three WOCE expeditions (a total of 152 days at sea) in the South Pacific Ocean, and the field phase of the proposed investigation has been successfully completed. The total CO[sub 2] concentration and pCO[sub 2] were determined at sea in 4419 water samples collected at 422 stations. On the basis of the shipboard analyses of SIO Reference Solutions for CO, and a comparison with the results of previous expeditions, the overall precision of our total CO[sub 2] determinations is estimated to be about [plus minus]2 uM/kg. The deep water data indicate that there is a CO[sub 2] maximum centered about 2600 meters deep. This appears to represent a southward return flow from the North Pacific. The magnitude and distribution of the CO, maximum observed along the 135.0[degrees]W meridian differ from those observed along the 150.5[degrees]W meridian due to Tuamotu Archipelago, a topographic high which interferes with the southward return flow. The surface water pCO[sub 2] data indicate that the South Pacific sub-tropical gyre water located between about 15[degrees]S and 50[degrees]S is a sink for atmospheric CO[sub 2].

Suppression of fine ash formation in pulverized coal flames
The second major ash producing mechanism is the generation of a submicron aerosol through a vaporization/condensation mechanism. When the ash size distribution is plotted in terms of number density, the submicron mode generally peaks at about 0. 1 [mu]m. When plotted in terms of mass, this mode is sometimes distinct from the residual ash mode, and sometimes merged into it. During diffusion-limited char combustion, the interior of the particle becomes hot and fuel-rich. The non-volatile oxides (e.g., Al[sub 2]O[sub 3], SiO[sub 2], MgO, CaO, Fe[sub 2]O[sub 3]) can be reduced to more volatile suboxides and elements, and partially vaporized. These reoxidize while passing through the boundary layer surrounding the char particle, thus becoming so highly supersaturated that rapid homogeneous nucleation occurs. This high nuclei concentration in the boundary layer promotes more extensive coagulation than would occur if the nuclei were uniformly distributed across the flow field. The vaporization can be accelerated by the overshoot of the char temperature beyond the local gas temperature. Although these particles represent a relatively small fraction of the mass, they can present a large fraction of the surface area. Thus, they are a preferred site for the condensation of the more volatile oxides later in …

Composition dependence of fluid thermophysical properties: Theory and modeling
Objectives are studies of equilibrium/nonequilibrium properties of asymmetric fluid mixtures through computer simulation (CS), development of predictive theories of mixture equilibrium properties, development and application of selection algorithm methodology for mixture equations of state, and use of theory to develop new engineering design models for fluid mixtures. Kirwood charging method CS of Lennard-Jones mixtures with large size ratios verified the Kirkwood-Buff/Baxter method of calculating chemical potentials. CS of n-butane showed that the rheology is not a function of system size. A modified stepwise regression algorithm was developed and applied to HFC R134a. An analytical expression was developed for conformal solution size correction for mixtures. The extended corresponding states theory (ECST) can be applied to systems having large polarity differences; an accurate representation was developed of bulk phase properties of water-hydrocarbon systems. It was found how to force ECST to reach the correct virial limit.

Rapid pressure swing absorption cleanup of post-shift reactor synthesis gas
The theoretical model for the absorption part of a particular type of RAPSAB cycle (Mode 3) (see Technical Progress Report No. 7) has been developed. The numerical simulations of the model compare well with the experimental results presented in the last report (Technical Progress Report No. 7). A number of experiments were carried out also for Mode 2 type of operation by varying the time for initial pressurization of the hollow fiber module as well as the total absorption time. These were done to provide a basis for comparison with the theoretical model to be developed later. We have initiated RAPSAB studies with reactive absorbents such as 19.5 % aqueous solution of diethanolamine (DEA) for the absorption of C0[sub 2] from a C0[sub 2]-N[sub 2] mixture. Six experiments were carried out using Mode 3 type of operation and a C0[sub 2]-N[sub 2] mixture containing 9.9% CO, and balance N[sub 2]. Excellent purification was obtained. No C0[sub 2] was observed in the purified high pressure gas outlet for absorption time of up to 14 seconds; the purified high pressure gas flow rate was also considerable. Module No. 5 was used for all experiments. The details of the module are given in …

Bench-scale testing of the multi-gravity separator in combination with Microcel
The primary objective of the proposed work is to design, install and operate an advanced fine coal processing circuit combining Microcel and MGS technologies. Both of these processes have specific advantages as stand-alone units. For example, the Microcel column is effective in removing ash-bearing mineral matter, while the MGS is capable of efficiently removing coal-pyrite composites. Therefore, by combining both of these unit operations into a single processing circuit, synergistic advantages can be gained. As a result, this circuit arrangement has the potential of improving coal quality beyond that which could be achieved using either one of the technologies individually. In addition to the primary objective, secondary objectives of the proposed test program will include: (1) Circuit Optimization: The performance of each unit operation, individually and combined, will be optimized by conducting parametric studies as a function of key operating variables. The goal of this work will be to maximize the rejections of pyritic sulfur and ash while maintaining a high energy recovery; and (2) Process Variability: The steady-state performance of the optimized processing circuit will be studied (i) by conducting several long-duration test runs over a period of several days and (ii) by testing coal samples from other sources …

PHENIX Conceptual Design Report
The PHENIX Conceptual Design Report (CDR) describes the detector design of the PHENIX experiment for Day-1 operation at the Relativistic Heavy Ion Collider (RHIC). The CDR presents the physics capabilities, technical details, cost estimate, construction schedule, funding profile, management structure, and possible upgrade paths of the PHENIX experiment. The primary goals of the PHENIX experiment are to detect the quark-gluon plasma (QGP) and to measure its properties. Many of the potential signatures for the QGP are measured as a function of a well-defined common variable to see if any or all of these signatures show a simultaneous anomaly due to the formation of the QGP. In addition, basic quantum chromodynamics phenomena, collision dynamics, and thermodynamic features of the initial states of the collision are studied. To achieve these goals, the PHENIX experiment measures lepton pairs (dielectrons and dimuons) to study various properties of vector mesons, such as the mass, the width, and the degree of yield suppression due to the formation of the QGP. The effect of thermal radiation on the continuum is studied in different regions of rapidity and mass. The e[mu] coincidence is measured to study charm production, and aids in understanding the shape of the continuum dilepton …

Catalytic hydrocarbon reactions over supported metals
During the past year we have completed our characterization of the factors that control the structure of fully oxidized W and Mo on silica and have established that support hydroxyl groups play a central role in dispersing and attaching cations to the support oxide. Work with M[sub 2](CO)[sub 4]Cp[sub 2](M[sub 2]=MoMo, WW, MoW) system has been very encouraging and continues to support the notion that it may be possible to control the structure of adsorbed catalysts (in this case generate metal dimers) by use of organometallic precursors. Techniques are being developed necessary to employ XPS as a means to characterize the attachment process and the oxidation state of the cations after various thermal and photolytic reduction steps.

Thick-target yields of iodine isotopes from proton interactions in Te, and the double-[beta] decay of [sup 128,130]Te
We report thick-target yields of [sup 126,128,130]I from the bombardment of natural Te targets with 15-, 30-, 45- and 50-MeV protons, together with the iodine production cross sections for 1.85- and 5.0-GeV protons. With these data, we have estimated the relative cosmic-ray induced production of [sup 126]Xe, [sup 128]Xe and [sup 13O]Xe in Te ores. These quantities affect the ratio of double-[beta] decay half-lives of [sup 13O]Te and [sup 128]Te. A revised correction of cosmic-ray induced xenon can change the half-life ratio by as much as 10%, from (3.52[plus minus]0.11) [times] 10[sup [minus]4] to (3.88[plus minus]0.14) [times] 10[sup [minus]4].

[beta][sup +] decay and cosmic-ray half-life of [sup 54]Mn
We performed a search for the [beta][sup +] branch of [sup 54]Mn decay. As a cosmic ray, [sup 54]Mn, deprived of its atomic electrons, can decay only via [beta][sup +] and [beta][sup [minus]] decay, with a half-life of the order of 10[sup 6] yr. This turns [sup 54] Mn into a suitable cosmic chronometer for the study of cosmic-ray confinement times. We searched for coincident back-to-back 511-keV [gamma]-rays using two germanium detectors inside a Nal(Tl) annulus. An upper limit of 2[times]10[sup [minus]8] was found for the [beta][sup +] decay branch, corresponding to a lower limit of 13.7 for the log ft value.
