Theoretical approach for enhanced mass transfer effects in duct flue gas desulfurization processes
Novel techniques designed for the enhancement of Ca(OH){sub 2} utilization in dry-sorbent injection (DSI) and duct-spray drying (DSD) were investigated in the Long Time Differential Reactor (LTDR), Short Time Differential Reactor (STDR), and 50-cfm pilot plant. At 2000-ppm SO{sub 2} and 60 percent relative humidity, the presence of up to 30-percent initial free moisture significantly increased sorbent reactivity with SO{sub 2}, compared to sorbent with equilibrium amount of moisture. The conversion decreased when the initial free moisture increased beyond 30--50 percent. The initial free moisture content and corresponding level of maximum sorbent conversion with SO{sub 2} varied with the surface area of the sorbent. Sorbent moisture capacity tests indicated that agglomeration of damp calcium silicate sorbent was a function of sorbent pore volume. Critical moisture content was increasing with specific surface area. Very little improvement in SO{sub 2} removal was obtained by DSI recycle operation downstream of humidification. Significant enhancement was achieved by DSI recycle upstream of humidification. Grinding of DSI solids with and without fly ash resulted in significant increase of surface area and pore volume and resulting reactivity with SO{sub 2}. Organic buffer additives were tested as potential enhancement of Ca(OH){sub 2} utilization during the DSD process. Bench-scale …

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts
Our previous studies (1,2) on the zerofield NMR spectra of Cu/Co catalysts revealed that the method of preparation sensitively influences the magnetic character of the Catalyst. Catalytic studies of the earlier investigators also (3) show similar influence on the product selectivity and indicate reproducible performance is critically dependent on the control and rigor of the preparation technique. To compliment the NMR results, we have made a thorough investigation of the Hysteresis character of the Cu/Co catalysts with the metal ratio varying from 0.2 to 4.0.

Shock-interface interaction: Current research on the Richtmyer- Meshkov problem
The basis for the study of the evolution of a shocked interface stems from the question of the Rayleigh-Taylor (RT) instability (Taylor 1950). Starting in the late 18th century, the stability of an interface submitted to gravitational forces was investigated for the case in which the density of one of the materials across the interface was negligible compared to the other. Taylor analyzed the case in which the Atwood number (ratio of the difference of the densities to their sum) is less than 1, and the acceleration of the system is constant. He determined that the interface was unstable to small perturbations only if the direction of the acceleration normal to the interface coincides with that of the density gradient. Richtmyer (1960) extended Taylor's analysis to the case of an implusive acceleration. His results implied that the interface would be unstable irrespective of the relative orientation of the velocity impulse and the density gradient. His predictions were verified experimentally by Meshkov (1969), and the Richtmyer-Meshkov (RM) instability became a subject of research in its own right. Experimental, numerical, and theoretical works address this problem. The RM problem has been studied with both the shock-tube and laser experiments. In this paper, …

Analyses of inter- and intra-patient variation in the V3 loop of the HIV-1 envelope protein
The third hypervariable domain of the HIV-1 gp120 envelope protein (V3) has been the focus of intensive sequencing efforts. To date, nearly one thousand V3 loop sequences have been stored in the HIV sequence database. Studies have revealed that the V3 loop elicits potent type-specific immune responses, and that it plays a significant role in cell tropism and fusion . The immunogenic tip of the loop can serve as a type-specific neutralizing antibody epitope, as well as a cytotoxic T-cell epitope. A helper T-cell epitope that lies within the amino terminal half of the V3 loop has also been characterized. Despite the richness of the immunologic response to this region, its potential for variation makes it an elusive target for vaccine design. Analyses of sibling sequence sets (sets of viral sequences derived from one person) show that multiple forms of the immunogenic tip of the loop are found within most HIV-1 infected individuals. Viral V3 sequences obtained from epidemiologically unlinked individuals from North America and Europe show extensive variation. However, some amino acid positions distributed throughout the V3 loop are highly conserved, and there is also conservation of the charge class of amino acid able to occupy certain positions relative …

Oxidation of hazardous waste in supercritical water: A comparison of modeling and experimental results for methanol destruction
Recent experiments at Sandia National Laboratories conducted in conjunction with MODEC Corporation have demonstrated successful clean- up of contaminated water in a supercritical water reactor. These experiments targeted wastes of interest to Department of Energy production facilities. In this paper we present modeling and experimental results for a surrogate waste containing 98% water, 2% methanol, and parts per million of chlorinated hydrocarbons and laser dyes. Our initial modeling results consider only methanol and water. Experimental data are available for inlet and outlet conditions and axial temperature profiles along the outside reactor wall. The purpose of our model is to study the chemical and physical processes inside the reactor. We are particularly interested in the parameters that control the location of the reaction zone. The laboratory-scale reactor operates at 25 MPa., between 300 K and 900 K; it is modeled as a plug-flow reactor with a specified temperature profile. We use Chemkin Real-Gas to calculate mixture density, with the Peng-Robinson equation of state. The elementary reaction set for methanol oxidation and reactions of other C{sub 1} and C{sub 2} hydrocarbons is based on previous models for gas-phase kinetics. Results from our calculations show that the methanol is 99.9% destroyed at 1/3 …

[Computer simulated images of radiopharmaceutical distributions in anthropomorphic phantoms]
We have constructed an anatomically correct human geometry, which can be used to store radioisotope concentrations in 51 various internal organs. Each organ is associated with an index number which references to its attenuating characteristics (composition and density). The initial development of Computer Simulated Images of Radiopharmaceuticals in Anthropomorphic Phantoms (CSIRDAP) over the first 3 years has been very successful. All components of the simulation have been coded, made operational and debugged.
