Notizen: [Auszug] Since a major step in the formation of gall-stones appears to be the bacterial 7-dehydroxylation of allocholic acid, it is reasonable to assume that the reduction or elimination of the bacteria responsible for the conversion might interfere with gall-stone formation. Because of its well-known ...

Notizen: Abstract In the experiments reported here we observed the generation of non-thermal, large amplitude acoustic surface waves at GHz frequencies on the surface of a GaAs crystal under intense illumination with 514.5 nm radiation from an Ar+ laser at room temperature. The acoustic surface waves were detected by optical Brillouin spectroscopy.

Thema: Maschinenbau

Notizen: Abstract The influence of the electrode potential on the corrosion behavior of a series of nickel- and cobalt-base gas turbine alloys has been investigated in a (mole %) 53Na2SO4+7CaSO4+40MgSO4 melt at 1073 and 1173 K and in a 90Na2SO4+10K2SO4 melt at 1173 K. Only acidic fluxing is observed in the (Na 2,Ca, Mg)SO4 melt at positive potentials while a protective scale rich in MgO is formed on all alloys at negative potentials. This scale prevents basic fluxing because MgO is insoluble in neutral and basic melts. The breakthrough potential for acidic fluxing is a function of the material composition. Increasing chromium content of the alloys extends the potential range of protective film formation. Acidic and basic fluxing are observed in the (Na, K)2SO4 melt. Acidic fluxing occurs at positive and basic fluxing at negative potentials. A protective scale is formed in an intermediate (neutral) potential range on the high-chromium alloys IN-597 and IN-738 LC. Here, too, the breakthrough potentials for acidic and basic fluxing are influenced by the composition of the alloys.

Notizen: Abstract The sulfide NaCrS2 has been identified in the internal corrosion zone of several nickel-base superalloys under basic fluxing conditions at very negative potentials in a 90% Na2SO4-10% K2SO4 melt at 1173 K. It can also be formed in the presence of carbon-contaminated sulfate. NaCrS2 can dissolve some Ti, Al, Ni, and Co; other elements, e.g., K, Mo, W, Nb, Ta, and Zr, could not be detected.

Notizen: Summary The topography of the funnel-canal organs of Carcinus maenas (Decapoda, Crustacea) and their stimulus-receiving cuticular and sensory apparatus were studied in the light and electron microscopes. About 4000 funnel-canal organs are situated within the exoskeleton of Carcinus. Almost all of them are on the distal segments of the walking legs, in particular on the epicuticular cap at the tip of the dactyl. They were not found to be arranged in groups or sensilla fields, and no sex-specific differences were observed. Characteristic features of the funnel-canal organs are as follows: (a) There is a terminal pore (0.5×0.8 μm diameter) in the cuticle, at the tip of a small projection. It is closed by a plug of electron-dense material. (b) The terminal sections of the dendrites are enclosed in a dendritic sheath up to ca. 10 μm below the pore. (c) The dendrites, 3–24 in number, end below the plug; none of the dendrites exhibits a tubular body; two of the dendrites are distinguished from the others by the greater number of microtubules in their outer segments. The structural characteristics, in particular the “gustatory pore” and the number of dendrites, are typical of bimodal receptors in arthropods. In such receptors, as in the contact chemoreceptors of insects and arachnids, mechano-and chemosensitive sensory cells are combined. This interpretation of the function of the funnel-canal organs is supported by electrophysiological data of other authors. The morphological parameters we find for the funnelcanal organs, in comparison with those of insect campaniform sensilla, provide clear evidence against the reclassification of the funnel-canal organs as “crustacean campaniform organs” proposed by Shelton and Laverack (1968).
