    Notizen: Abstract The so-called anode effect, particularly important in industrial alumina electrolysis, has mostly been interpreted as the consequence of altered wettability of the electrode surface by the melt. By means of a mathematical model assuming isolated large bubbles in contact with the electrode it is shown that the anode effect is the result of the combined action of fluid dynamics and wettability. The interpretation of the incipience of the anode effect obtained by means of a previous, completely different mathematical model is confirmed. The theoretical results are compared with experimental data by various authors.

    Effect of alumina concentration on the incipience of the anode effect in aluminium electrolysis (1999)
    Springer
    Journal of applied electrochemistry 29 (1999), S. 779-788 
    Details
    ISSN: 1572-8838
    Schlagwort(e): aluminium ; anode effect ; gas evolution ; fluid dynamics ; two-phase flow
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Elektrotechnik, Elektronik, Nachrichtentechnik
    Notizen: Abstract The cause of the incipience of the anode effect in alumina reduction cells has long been a controversial issue. The most plausible interpretations are (i) an insufficient release of the gaseous phase from underneath the anode surface together with the action of diminished wettability and (ii) the depletion of oxygen-containing ions at the anode surface to result in the limiting current condition. It is shown by means of a mathematical model that each of these effects may be active. The predominant mechanism depends on the operational conditions. Theoretical results are compared with experimental data.

    Computer-assisted 3D reconstruction of the terminal branches of the cerebral arteries (1994)
    Springer
    Neuroradiology 36 (1994), S. 173-180 
    Details
    ISSN: 1432-1920
    Schlagwort(e): Anterior cerebral artery ; Terminal branches ; Three-dimensional neuroimaging ; Computer graphics ; Anatomical model ; Human

    Thema: Medizin
    Notizen: Abstract We present a three-dimensional anatomical computer model of the terminal branches of the anterior cerebral artery, acquired from equidistant serial anatomical slices of three brains. The reconstructions provide a clear picture from all angles of the complicated course of the terminal branches of the cerebral arteries, which can help to identify them on conventional and magnetic resonance angiography. Our rendition of the cerebral arteries can also be matched with CT, MR or PET images to indicate the areas of extension of individual branches, allowing neuromorphological and functional correlations.
