X-ray photoelectron spectroscopy (XPS) is used to study the bonding structure at the iron site of cytochrome c and the bonding of rare earth ions to the phosphate oxygens of ATP. Radiation effects are studied on several amino acid and simple peptide model systems. The emission spectrum of the x-ray source is calculated from literature references. The distributions of photon energy as a function of photon frequency and as a function of take-off angle are obtained. From these distributions, the radiation dose absorbed by an organic sample is found to be 10/sup 6/ rads/sec. The C 1s and N 1s spectra of amino acids and peptides are studied to characterize an internal reference standard for protein XPS spectra. Samples of native cytochrome c prepared from solutions of pH 1.5, 3, 7, and 11 are studied. Control samples include porphyrin cytochrome c (PCC), the metal free analogue of the native protein, and microperoxidase (MP), a mixture of heme peptides derived from the peptic digestion of cytochrome c. These samples show two S 2p peaks. The first peak has a binding energy (BE) of 163 eV, which corresponds to the S containing amino acids; the second peak is shifted to 167 eV. …

The feasibility of using fluidized-bed combustors in power and steam plants is being evaluated. The concept involves burning fuels such as coal in a fluidized bed of either a naturally occurring, calcium-containing limestone or dolomite or in a synthetically prepared calcium-containing stone. The calcium oxide in the stone reacts with the sulfur released during combustion to form calcium sulfate, which remains in the bed, thus decreasing the level of SO/sub 2/ in the flue gas. Levels of NO/sub x/ in the flue gas are also low. The effect of operating variables and type of stone on the levels of SO/sub 2/ and NO/sub x/ is being determined. Behavior of trace elements during combustion has been preliminarily evaluated. The properties of a fluidized bed at minimum fluidization at different temperatures and pressures have been determined. The CaSO/sub 4/ produced in the combustion process is regenerated to CaO for reuse in the combustor by reductive decomposition at 1095/sup 0/C (2000/sup 0/F). The effects of operating variables on sulfur release during regeneration are being evaluated. Another regeneration process, solid-solid reaction of CaSO/sub 4/ with CaS, is also being investigated. Fundamental investigations of the kinetics of sulfation and regeneration reactions for the natural and …

A proposed technique to remove small areas, <2,000 m/sup 2/, of contaminated soil is discussed along with the results of an actual excavation. Based on the results of a trial excavation in uncontaminated soil and an excavation of two trenches in contaminated soil, it is concluded that the techniques described are a satisfactory means of contaminated soil removal. It can be done safely with a release of airborne plutonium a factor of 10 or more below the Environmental Protection Administration (EPA) limit.

This paper focuses on the comparative economics of fast breeder reactors versus light water reactors and develops an internally consistent set of financial techniques whereby a utility may determine and compare the costs of generating power with either system. The general methodology is used here to estimate the break-even capital costs for the breeder as a function of future uranium prices but is equally applicable to other reactor types. It is shown that by the time the breeder reactor (breeder) is commercially available, it is likely a utility would select a breeder even though its capital cost might be twice that of a light water reactor (LWR).

This picture immortalizes the signing of the 25-year lease at $25 per year of the 1884 Little Rock School building for the purpose of establishing it as a museum. Pictured, left to right are: A. F. Weaver, President of the Mineral Wells Heritage Association; L. Gordon Nelson, Vice President; Mrs. Gordon Nelson, Chairperson for the Restoration Committee. Seated is Bill Hall, Superintendent of Mineral Wells Schools. The photograph was taken in July, 1975. The Little Rock School, in 2007, remains a museum dedicated to the preservation of the History of Mineral Wells. This picture appears in "Time Was in Mineral Wells...." on page 173.
