one or more adenosine triphosphatase units in discrete assemblies (Ernster et al., 1973). If proved, this finding would present a very serious challenge to the classical chemiosmotic view, which is necessarily based on a generalized rather than a specific association of the oxidation and phosphorylation processes. In contrast, the presence of assemblies is in no way damaging to the p-zone inter...

A reaction involving the catalytic oxidation of glucose by the enzyme glucose oxidase is employed as a first spatially resolved experimental realization of a nonclassical A + C f C + Products chemical reaction. This heterogeneous kinetics experiment models the operation of optical glucose sensors. One-dimensional nonclassical reaction kinetics, manifested in anomalous rate laws, are observed. T...

The ionization response of hydrocarbons In a hydrogen-atmosphere flame was compared to that of a normal flame ionization detector used in gas chromatography. Absolute response in the hydrogen-atmosphere flame lonizatlon detector (HAFID) was found to be two orders of magnitude less than that of the normal FID. This reduced response is attributed both to oxidation of hydrocarbons in the precombus...

By applying microspectrophotometry to the sporangiophore of Phycomyces blakesleeanus wild-type and the albino car-10(-) type II, absorption spectra were obtained for 1- to 5-day cultures. Spectra in the growing-zone of the wild-type during Stage IVb, taken from 0.1 to 3 mm below the base of the sporangium, show two distinctly different spectra: one is more characteristic of a carotene, the othe...

[1] Iron solubility measurements in the Mauritanian upwelling and the adjacent Open Ocean of the Tropical Atlantic show for all stations lower values in the surface mixed layer than at depth below the pycnocline. We attribute this distribution to a combination of loss terms, chiefly photo-oxidation of organic ligands in the surface, and supply terms, predominantly from the release of ligands fr...

A new high-temperature method for the deposition of gas-tight silicon carbide protective coatings with low gas permeability has been developed. The free carbon atoms form during pyrolysis hydrocarbon molecules. In turn, reacts molten contained in subsurface substrate layers and/or vapor. source vapor serves heated zone a reactor furnace. Such effectively protect SiC-C-Si and SiC-C-MoSi2 ceramic...

Abstract The Girilambone copper deposit of New South Wales, Australia, serves as an end-member model for development a classic oxidation-zone profile in environment virtually free both the effects active tectonics and significant fluctuation local water table. oxidation zone other deposits may be interpreted history recently tectonics, palaeoclimate, water-table stability by comparison to depos...

The increasing amount of municipal solid waste (MSW) is a growing challenge that current waste-treatment practices are having to face. Therefore, technologies can prevent from ending up in landfill sites have come the fore. One produces valuable product waste, namely synthesis gas, gasification. raw material this technology so-called Refuse-Derived Fuel, which made MSW. Three separate zones loc...

AIMS The aim of this study was to characterize redox changes in the nuclei and cytosol occurring during the mitotic cell cycle in the embryonic roots of germinating Arabidopsis seedlings, and to determine how redox cycling was modified in mutants with a decreased capacity for ascorbate synthesis. RESULTS Using an in vivo reduction-oxidation (redox) reporter (roGFP2), we show that transient ox...
