Les fosses cérémonielles huichol sont des lieux où se confrontent diverses intentions et dynamiques rituelles. Il existe un désir de voir les statues des ancêtres et les êtres sacrificiels qui résident à l’intérieur de la fosse. Mais seuls les spécialistes rituels se consacrant à la recherche de vision peuvent y parvenir, en s’identifiant avec les ...

Methylviologen dication (MV/sup 2 +/) forms charge-transfer (CT) complexes with EDTA, triethanolamine (TEOA), and cysteine (Cys) in aqueous solution. The complexes of EDTA and TEOA show enhanced tail absorption from 320 nm well into the visible region; the Cys complex shows a discrete absorption band in the 350-380-nm region.

Canadian Journal of Chemistry, 1992
A general method for the electrosynthesis of anionic and mixed ligand nonelectrolytic thiocyanato complexes of transition metals has been developed by the oxidation of sacrificial metal anodes in aqueous, or aqueous ethanolic, medium containing ammonium thiocyanate at room temperature and at an applied potential of 2–7 V. The method is rapid and gives

Print your membrane: Rapid prototyping of complex 3D-PDMS membranes via a sacrificial resist
Journal of Membrane Science, 2015Abstract Polydimethylsiloxane is a translucent silicone material present in most lab-on-a-chip devices. In membrane technology, polydimethylsiloxane provides a separation barrier for various applications such as oxygenation, vapor recovery and nanofiltration.

Catalytic methyl transfer reactions from methyl tosylate to 1-octanethiol catalyzed by heptamethyl cobyrinate perchlorate, [Cob(II)7C(1)ester]ClO(4), were investigated under electrochemical conditions. As a model study for the cobalamin-dependent methyl transfer reaction from methyltetrahydrofolate to homocysteine, controlled-potential electrolyses ...

Abstract Offshore oil and gas platforms, pipelines and marine structures are most often cathodically protected with sacrificial anodes, which require periodic replacement. Rising costs associated with traditional diver-placed retrofits have necessitated development of surface and remotely operated vehicle (R.O.V.) deployed systems ...
