Leach and soil column tests with stored redox sludge

Description: The leachabilities of /sup 90/Sr, /sup 239/Pu, and /sup 137/Cs from solids in Tank 108-SX were determined. Through 21 leach cycles covering a 3.5 day period, 63 volumes of leachate removed 1.4, 4.6, and 19.2% of the /sup 239/Pu, /sup 90/Sr, and /sup 137/Cs, respectively, from the 108-SX solids. With the exception of the first few leachates, the /sup 239/Pu concentrations in the leachates were less than maximum permissible concentration in drinking water for 168-h/wk exposure. A composite of the… more

ELECTROCHEMISTRY OF EXCITED MOLECULES: PHOTO-ELECTROCHEMICALREACTIONS OF CHLOROPHYLLS. I

Description: Semiconductors with a sufficiently large energy gap, in contact with an electrolyte, can be used as electrodes for the study of electrochemical reactions of excited molecules. The behavior of excited chlorophyll molecules at single crystal ZnO-electrodes has been investigated. These molecules inject electrons from excited levels into the conduction band of the electrode, thus giving rise to an anodic photocurrent. The influence of various agents on this electron transfer has been studied. In th… more

BRANCHED ALKANES FROM BLUE-GREEN ALGAE

Description: Branched alkanes from blue-green algae were separated on a 750 feet high resolution capillary gas chromatographic column. The mixture was found to be 90% of 1:1 ratio 7-methyl, and 8-methyl-heptadecane, and 10% of 6-methylheptadecane. An optical rotation of +2.5 {+-} 0.5 was obtained on a 5 mg of mixture.

PARTICLE DETECTORS BASED ON NOBLE LIQUIDS

Description: In order to build a thin particle detector with 10 micron spatial resolution and automatic readout, the avalanche of ionization electrons in high electric fields in liquid argon and liquid xenon has been studied. We present a scheme using an array of points that could be used to make a reliable liquid argon filled detector. The avalanche pulses in liquid xenon have a rise time more than three orders of magnitude faster than that in liquid argon, suggesting that the positive charge carriers are … more

METHANE INCORPORATION BY PROCARYOTIC PHOTOSYNTHETICMICROORGANISMS

Description: The procaryotic photosynthetic microorganisms Anacystis nidulans, Nostoc and Rhodospirillum rubrum have cell walls and membranes that are resistant to the solution of methane in their lipid components and intracellular fluids. But Anacystis nidulans, possesses a limited bioxidant system, a portion of which may be extracellularly secreted, which rapidly oxidizes methane to carbon dioxide. Small C{sup 14} activities derived from CH{sub 4} in excess of experimental error are detected in all the ma… more

ISOLEUCYL-tRNA-SYNTHETASE A FLUORESCENCE STUDY OP THE BINDINGPROPERTIES OF THE SYNTHETASE FROM ESCHERICHIA COLI

Description: Fluorescence properties of purified isoleucyl-tRNA-synthetase isolated from E. coli B have been studied. No changes in the quantum yield, energy or polarization of the emission were detected in the presence (either individually or in combinations) of the substrates and cofactors required for activation of L-isoleucine. In 2.5 M urea enzyme activity and intrinsic fluorescence intensity (at 340 nm) each decrease with time, showing similar kinetics and rate constants. The rate of this decay is red… more

SEARCH FOR T-VIOLATION IN THE INELASTIC SCATTERING OF ELECTRONSFROM A POLARIZED PROTON TARGET

Description: The authors have searched for an asymmetry in the inelastic scattering of electrons from a polarized proton target in the region of resonance excitation, at values of four-momentum transfer squared of 0.4, 0.6 and 1.0 (GeV/c){sup 2}. Data were also taken using an incident positron beam in order to distinguish any possible effect of time-reversal violation from that due to higher-order ({alpha}{sup 3}) contributions to the scattering. No sizeable violation of time-reversal invariance was found.

PHOTOCHEMICAL COUPLING OF BENZO [a]PYEENE WITH 1-METHYLCYTOSINE.POSSIBLE MECHANISM OF THE LINKAGE IN VIVO

Description: Irradiation of benzo[a]pyrene 1 with 1-methylcytosine hydrochloride 2a (molar ratio 1:10) at 3500 {angstrom} in methanol-acetone produces the 6-(1-methylcytos-5-yl)-benzo[pa]pyrene 3. The structure of the photoproduct shows the hydrocarbon bound through the most active 6-carbon atom to the nucleophilic 5-position of the base. The specific substitution of both moieties combined with other data allows them to understand the carcinogenic activity of the hydrocarbon and thereby to propose a possibl… more

Thulium oxide fuel characterization study: Part 2, Environmental behavior and mechanical, thermal and chemical stability enhancement

Description: A study was performed of the correlation between fuel form stability and exposure environment of (temperature and atmosphere). 100% Tm/sub 2/O/sub 3/, 80% Tm/sub 2/O/sub 3//20% Yb/sub 2/O/sub 3/ and 100% Yb/sub 2/O/sub 3/ wafers were subjected to air, dynamic vacuum and static vacuum at temperatures to 2000/sup 0/C for times to 100 hours. Results showed the Tm/sub 2/O/sub 3//Yb/sub 2/O/sub 3/ cubic structure to be unaffected by elemental levels of iron, aluminum, magnesium and silicon and unaff… more

Measurement of Pair Interactions in Neodymium Ethyl Sulfate

Description: The EPR spectrum of single ions of /sup 143/Nd in a crystal of Neodymium Ethyl Sulfate, predominantly of isotope /sup 142/Nd, was observed under condition of very high Boltzmann factor, i.e., high fields and low temperatures. It was found that the interactions with neighboring ions displaced the hyperfine lines from uniform spacing, and that by measuring the deviation it was possible to find the nearest neighbor interaction. The departure from a purely magnetic dipolar interaction is smaller th… more

Thulium-170 oxide heat source experimental and analytical radiation and shielding study

Description: Radiation dose rates from three thulium-170 oxide sources (20.7, 10.0 and 5.0 thermal watts) were measured through three thicknesses (1/4, 1/2 and 1 inch) of absorber by thermoluminescent dosimetry techniques. Absorber materials used were aluminium, stainless steel, lead, tungsten and depleted uranium. Resultant radiation doses were measured at 19 and 100 cm.

Initial objectives of on-site empirical modelling of thermal plumes: A preliminary evaluation of a river-site and a lake-site thermal plume

Description: This report recommends developing a statistical model to characterize the three-dimensionall pattern of thermal plumes, It indicates the danger of drawing detailed conclusions on the basis of a small number of observations, and emphasizes the need for proper interpretation of empirical measurements, Two reports, on the discharges (1) from the Dresden Power Station into the Illinois River and (2) from Waukegan Station into-Lake Michigan are analyzed. In conclusion, a plan for interpretation of t… more
