Testing proton spin models with polarized beams (open access)

Testing proton spin models with polarized beams

We review models for spin-weighted parton distributions in a proton. Sum rules involving the nonsinglet components of the structure function xg{sub 1}{sup p} help narrow the range of parameters in these models. The contribution of the {gamma}{sub 5} anomaly term depends on the size of the integrated polarized gluon distribution and experimental predictions depend on its size. We have proposed three models for the polarized gluon distributions, whose range is considerable. These model distributions give an overall range is considerable. These model distributions give an overall range of parameters that can be tested with polarized beam experiments. These are discussed with regard to specific predictions for polarized beam experiments at energies typical of UNK.

Request for One-Time Shipment of 32 Watt PU-328 Source in 9968 Packaging (open access)

Request for One-Time Shipment of 32 Watt PU-328 Source in 9968 Packaging

The 9968 package is designed for surface shipment of fissile and other radioactive materials where a high degree of double containment is required. The use of the 9968 radioactive material package for a one time shipment of a 32 watt heat source versus the SARP approved maximum 30 watt heat source is addressed in this report. The analyses show that the small increase in heat load from 30 watts to 32 watts does not substantially increase internal temperatures or pressures that would approach limits for the package. Also, the weight of the content is within the current 9968 package limits. It is concluded that the 32-watt heat source can be safely shipped in the 9968 package and therefore a waiver to ship the source is justified.

Pulsed laser kinetic studies of liquids under high pressure (open access)

Pulsed laser kinetic studies of liquids under high pressure

A high pressure apparatus constructed for measuring the rates of reactions in liquids under pressures ranging from 1 atm to 2000 atm has been used to measure the complexation kinetics of molybdenum hexacarbonyl reacting with 2,2-bipyridine, 4,4{prime}-dimethyl-2-2{prime}-bipyridine and 4,4{prime}-diphenyl-2-2{prime} bipyridine in toluene. Pentacarbonyl reaction intermediates are created by a 10 nsec flash of frequency tripled Nd:YAG laser light. Measured activation volumes for chelate ligand ring closure indicate a change in mechanism from associative interchange to dissociative interchange as steric hindrance increases. A similar high pressure kinetics study of molybdenum carbonyl complexation by several substituted phenanthrolines is now well advanced that indicates that with the more rigid phenanthroline ligands steric effects from bulky substituents have less effect on the ring closure mechanism than in the case of the bipyridine ligands. An experimental concentration dependence of the fluorescence quantum yield of cresyl violet has been harmonized with previously published contradictory reports. Fluorescence of cresyl violet in various solvents and in micellar systems has also been systematically explored.

Two dimensional NMR and NMR relaxation studies of coal structure (open access)

Two dimensional NMR and NMR relaxation studies of coal structure

This report covers the progress made on the title project for the project period. Four major areas of inquiry are being pursued. Advanced solid state NMR methods are being developed to assay the distribution of the various important functional groups that determine the reactivity of coals. Special attention is being paid to methods that are compatible with the very high magic angle sample spinning rates needed for operation at the high magnetic field strengths available today. Polarization inversion methods utilizing the difference in heat capacities of small groups of spins are particularly promising. Methods combining proton-proton spin diffusion with [sup 13]C CPMAS readout are being developed to determine the connectivity of functional groups in coals in a high sensitivity relay type of experiment. Additional work is aimed at delineating the role of methyl group rotation in the proton NMR relaxation behavior of coals.

Evaluation of the WIND System atmospheric models: An analytic approach (open access)

Evaluation of the WIND System atmospheric models: An analytic approach

An analytic approach was used in this study to test the logic, coding, and the theoretical limits of the WIND System atmospheric models for the Savannah River Plant. In this method, dose or concentration estimates predicted by the models were compared to the analytic solutions to evaluate their performance. The results from AREA EVACUATION and PLTFF/PLUME were very nearly identical to the analytic solutions they are based on and the evaluation procedure demonstrated that these models were able to reproduce the theoretical characteristics of a puff or a plume. The dose or concentration predicted by PLTFF/PLUME was always within 1% of the analytic solution. Differences between the dose predicted by 2DPUF and its analytic solution were substantially greater than those associated with PUFF/PLUME, but were usually smaller than 6%. This behavior was expected because PUFF/PLUME solves a form of the analytic solution for a single puff, and 2DPUF performs an integration over a period of time for several puffs to obtain the dose. Relatively large differences between the dose predicted by 2DPUF and its analytic solution were found to occur close to the source under stable atmospheric conditions. WIND System users should be aware of these situations in which the …

A comparison of the WIND System atmospheric models and MATS data (open access)

A comparison of the WIND System atmospheric models and MATS data

The results produced by two of the WIND System atmospheric models, PUFF/PLUME and 2DPUF, were compared with a select group of eight MATS experiments to determine the performance of the models. Three of the MATS experiments employed TRAC vehicle sampling and the remaining five used a line of fixed samplers. The performance of the models was based on certain dispersion characteristics that are important in emergency response situations. Both PUFF/PLUME and 2DPUF were executed with the same source term and meteorological data. When the numerical results from the models were compared to the observed values from the MATS experiments, it was found that 2DPUF produced concentrations and plume widths that were closer to the observed values than PUFF/PLUME. Both models did not produce any bias in the values of the concentration when individual data points were examined; however, PUFF/PLUME consistently overpredicted the peak and total concentrations. 2DPUF did not exibit any bias in the peak and total concentrations. When wind direction errors were removed, 80--84% of the concentrations from PUFF/PLUME and 88% of the concentrations from 2DPUF where within a factor of 10 of the observed values. In some instances, both models were able to predict concentration values that were …

Innovative Clean Coal Technology (ICCT): 180 MW demonstration of advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from coal-fired boilers. Technical progress report, second quarter 1992

This quarterly report discusses the technical progress of a US Department of Energy (DOE) Innovative Clean Coal Technology (ICCT) Project demonstrating advanced tangentially-fired combustion techniques for the reduction of nitrogen oxide (NO{sub x}) emissions from a coal-fired boiler. The project is being conducted at Gulf Power Company`s Plant Lansing Smith Unit 2 located near Panama City, Florida. The primary objective of this demonstration is to determine the long-term effects of commercially available tangentially-fired low NO{sub x} combustion technologies on NO{sub x} emissions and boiler performance. A target of achieving fifty percent NO{sub x} reduction using combustion modifications has been established for the project. The stepwise approach that is being used to evaluate the NO{sub x} control technologies requires three plant outages to successively install the test instrumentation and the different levels of the low NO{sub x} concentric firing system (LNCFS). Following each outage, a series of four groups of tests are performed. These are (1) diagnostic, (2) performance, (3) long-term, and (4) verification. These tests are used to quantify the NO{sub x} reductions of each technology and evaluate the effects of those reductions on other combustion parameters such as particulate characteristics and boiler efficiency. This technical progress report presents the …

Effects of catalytic mineral matter on CO/CO{sub 2} temperature and burning time for char combustion. Quarterly progress report No. 12, July--September 1992 (open access)

Effects of catalytic mineral matter on CO/CO{sub 2} temperature and burning time for char combustion. Quarterly progress report No. 12, July--September 1992

Results (solid-1600K, open-2000K surface temperature) from Fig.3 show that oxygen and nitrogen distributions are almost same although there is a little particle shrinkage (r{sub o}=0.009cm). C0{sub 2}/CO ratio drop significantly as the temperature increases, which is opposite to experimental results reported earlier. The cause of this behavior is mainly due to the lack of gas phase CO oxidation. Therefore, C0{sub 2}/CO ratio are directly related to C0{sub 2} and CO production of the heterogeneous reaction, which generates less C0{sub 2} as the temperature goes up. To get CO oxidation in the gas phase boundary layer, we may need to incorporate more elementary reactions. But the computation time currently used for one ignition-extinction calculation is about 2 Cray CPU hours, which is very long, and will be longer if we incorporate full reaction kinetics. Actually we don`t need temperature and mass fraction distribution through the whole time span, there`s a need to develop a gas phase model which calculates distributions for only one surface temperature. A model incorporating full reaction set is under development using the time dependent results of SCOM as an initial guess.

Transformations of Toluene Radical Cation in ZSM-5 and Silicalite (open access)

Transformations of Toluene Radical Cation in ZSM-5 and Silicalite

Toluene radical cations produced by {gamma} irradiation at 77 K in ZSM-5 and Silicalite (isomorphous with ZSM-5 but nonpolar) undergo a reversible transformation to the norbornadiene radical cation at temperatures {le}150K. The transformation occurs to a greater extent in the more polar zeolite (ZSM-5). The substrate concentration plays an important role. Toluene radical cations undergo ion-molecule reactions to give benzyl radicals at low substrate loading at temperatures >200 K. At higher concentration, different adsorption sites become populated which allow the transformation to norbornadiene radical cation to take place.
