Radiation effects and metalloproteins studied by x-ray photoelectron spectroscopy (open access)

Radiation effects and metalloproteins studied by x-ray photoelectron spectroscopy

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. …

Study on reduction of accessory horsepower requirements. Fourth quarterly progress report (open access)

Study on reduction of accessory horsepower requirements. Fourth quarterly progress report

The program objective is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial three program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. During this quarter the major program accomplishments were: selection of candidate belt-drive concepts; completion of Phase III baseline vehicle drive systems physical and operational envelopes; completion of analysis for a mechanically controlled direct-operated belt drive with input programming; and completion of design layout and analysis for a hydromechanically controlled, servo-operated belt drive with output-speed sensing.

Development program on pressurized fluidized-bed combustion. Annual report, July 1, 1974--June 30, 1975 (open access)

Development program on pressurized fluidized-bed combustion. Annual report, July 1, 1974--June 30, 1975

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 …

Goals study for technical development and economic evaluation of the compound parabolic concentrator concept for solar energy collector applications (open access)

Goals study for technical development and economic evaluation of the compound parabolic concentrator concept for solar energy collector applications

The Argonne National Laboratories, contracted with Arthur D. Little, Inc. (ADL), to perform a 6 week goal study for the purpose of evaluating the technical applicability and the economic viability of the compound parabolic concentrator (CPC) concept for all solar energy applications except large central power plants. During this period, we studied the use of CPC units in a large number of residential, industrial, and commercial applications. The predicted performance of CPC augmented solar collectors was compared with other available solar collectors. Application of the CPC to on-site power generation using solar Rankine power generation techniques was studied in detail. Techniques and costs for fabricating CPC collectors were studied. Collectors with insulation and with full-surface reflectors were studied along with the use of CPC augmentation for evacuated receivers with selective surfaces. Manufacturing costs are compared with those reported by others. A qualitative comparison was made between the various classes of solar collectors that are either presently available or are expected to become available in the near future. Comparative energy costs for various collectors are discussed based upon the predicted performance and the estimated costs for manufacture. The problems of introducing the CPC, or other advanced technology type of solar collectors, …

Summary report of soil removal preliminary excavations. (Report No. ES-389-75-171)

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.
