The case of a brominated RNA crystal structure determination in which standard three-wavelength MAD phasing was unsuccessful because of fast X-ray-induced debromination was reinvestigated [Ennifar et al. ( 2002), Acta Cryst. D58, 1262 - 1268]. It was found ...
The effective fraction of delayed photoneutrons (ph) has been theoretically defined and experimentally determined in various different configurations of the LWR-PROTEUS critical facility. The peculiarity lies in the fact that the reactor has D2O in only on ...
Investigations on a polished thin section (PTS) by reflected-light microscopy, laser micro-Raman spectroscopy, and cathodoluminescence of the Bencubbin meteorite revealed the presence of diamond grains ranging in size from 200 nm to 1 mum in Fe-Ni metal, s ...
The photophysical properties of the triple-stranded dimetallic helicates [Ln2(LC−2H)3]·H2O (Ln = Nd, Sm, Dy, Yb) are determined in water and D2O solutions, and energy transfer processes are modeled for SmIII. The luminescence of NdIII, SmIII, and YbIII is ...
Aq. solns. of formic acid were exptl. investigated in a modified sweeping gas membrane distn. (SGMD) configuration. A thermostated sweeping gas was used in order to enhance the mass transfer performance. A new tubular module was designed and built for this ...

Dissection of complex processes using model organisms such as yeasts relies heavily upon the use of conditional mutants. We have generated a collection of fission yeast mutants sensitive to dimethylsulphoxide (DMSO). Among these we have found a mutant in t ...
Critical experiments involving fuel pin gamma-scans have been performed to characterise total fission reaction rate axial distributions in a Westinghouse SVEA-96+ assembly under full-density water moderation [these investigations are part of the co-operati ...
The water-soluble complexes [{RuCl2(mTPPMS)(2)}(2)], [RuCl2(PTA)(4)], [RhCl(mTPPMS)(3)], [RhCl(mTPPTS)(3)], and [RhCl(PTA)(3)] (mTPPMS=sodium salt of meta-sulfonatophenyl-diphenylphosphine, mTPPTS=sodium salt oftris(meta-sulfonatophenyl) phosphine, and PTA ...
Accurate critical experiments have been performed for the validation of total fission (Ftot) and 238U-capture (C8) reaction rate distributions obtained with CASMO-4, HELIOS, BOXER, and MCNP4B for the lower axial region of a real Westinghouse SVEA-96 + fuel ...
