    Notes: Summary Serial CT investigations of 3 patients with histologically confirmed Creutzfeldt-Jakob disease revealed persisting slight brain atrophy to progressive extreme atrophy corresponding to the absolute, not the individual duration of illness. No correlation was observed between CT findings and the patients' condition or electroencephalographic results. In one case with a duration of about 16 months and a terminal brain weight of 750 g a massive bilateral, later unilateral subdural hygroma appeared which probabely was caused by retraction of the brain showing an enormous atrophy.

    Temporal evolution of electroencephalographic abnormalities in Creutzfeldt-Jakob disease (1989)
    Springer
    Journal of neurology 236 (1989), S. 456-460

    Notes: Summary Frequent serial EEG investigations of three patients with neuropathologically confirmed Creutzfeldt-Jakob disease lasting 13, 24 and 68 weeks revealed typical periodic activity of short duration with stereotyped bilateral sharp waves at the 7th, 8th, and 12th week, respectively, after the onset of symptoms. During the later stages, there were several deviations from this typical pattern. However, periodic activity was preceded between the 3rd and 9th week by intermittent localized or lateralized delta rhythms, which gradually changed into periodic activity. This early temporal evolution of EEG abnormalities may be helpful in the early diagnosis of Creutzfeldt-Jakob disease when accompanied by other investigations to exclude other causes of intermittent delta rhythms.

    Bildungsweise und Struktur des Pentabromocarbonat-Anions [[CBr5⊖]n - Zur Oxidation von Enaminen (1976)
    Weinheim : Wiley-Blackwell

    Description / Table of Contents: Formation and Structure of the Pentabromocarbonate Anion [CBr5⊖]n - On the Oxidation of En-aminesOxidation of enamines 5 with tetrabromomethane yields stable crystalline pentabromocarbonates 6, which may easily be converted into the corresponding perchlorates 7. From the pentabromocarbonates, tetrabromomethane cannot be extracted either by organic solvents or by heating in vacuo; with silver nitrate, however, silver bromide can be precipitated from tetraphenylphosphonium pentabromocarbonate (9). If labelled 9 - prepared from tetraphenylphosphonium [82Br]bromide and tetrabromomethane - is treated with silver nitrate, all the activity is found in the silver bromide precipitate. This is clear evidence against a trigonal bipyramidal structure of the pentabromocarbonate anion CBr5⊖]n.
    Notes: Bei der Oxidation von Enaminen 5 mit Tetrabrommethan entstehen stabile kristalline Pentabromocarbonate 6, die sich leicht in die entsprechenden Perchlorate 7 überführen lassen. Aus den Pentabromocarbonaten kann Tetrabrommethan weder durch Extraktion mit organischen Solventien noch durch Erhitzen i. Vak. abgespalten werden, mit Silbernitrat kann jedoch aus Tetraphenylphosphonium-pentabromocarbonat (9)Silberbromid ausgefällt werden. Bei der Umsetzung von markiertem 9 - dargestellt aus [82Br] Tetraphenylphosphoniumbromid und Tetrabrommethan - mit Silbernitrat findet man die Gesamtaktivität im Silberbromid-Niederschlag. Dies spricht gegen die Struktur einer trigonalen Bipyramide für das CBr5⊖]n-Anion.

    Prediction of the properties of model polymer solutions and blends (1994)

    Notes: In this work we present an extension of the statistical associating fluid theory (SAFT) developed for associating fluids by applying this extension to polymer solutions and blends. The polymer molecule is modeled as a flexible chain made of bonded spherical segments. These segments interact with the Lennard-Jones potential. The extension of SAFT is compared with molecular simulation results for polymer solutions and blends. Since the same force model is used in the simulation and theory, this comparison is a strong test of the assumptions made in deriving the theory. Results are presented for pure polymers of up to 50 segments long, polymer solutions of a polymer 20 segments long dissolved in its own monomer, and blends of polymers of 25 segments each. The theory produces results that are in better agreement with simulation results than the Flory-Huggins theory for the systems studied.

    Kathodische Korrosion von Blei im Erdboden (1969)

    Description / Table of Contents: Cathodic corrosion of lead in the soilCathodic corrosion of lead in the soil can be expected in exceptional cases only. The corrosion found on a particular lead cable could be simulated in the laboratory. It could be confirmed, that  -  probably by decomposition of primary lead hydride  -  metallic lead is deposited below layers of Ca and Mg compounds already at potentials below -1,7 V. A special switching method was developed to account for breakthrough polarisation.
    Notes: Kathodische Korrosion von Blei im Boden ist grundsätzlich nur in Ausnahmefällen zu erwarten. Diese an einem Kabel gefundene Korrosion wurde im Laboratorium nachgebildet. Hierbei konnte bestätigt werden, daß unter Deckschichten aus Calcium- und Magnesiumverbindungen bei Potentialen schon unter -1,7 V metallisches, Blei abgeschieden wurde, wahrscheinlich durch Zersetzung von primär entstandenem Bleihydrid. Für derartige Untersuchungen wurde eine spezielle Schaltmethode entwickelt, bei welcher auch die Durchtrittspolarisation berücksichtigt wird.

    Slip velocity of particulate solids in vertical tubes (1966)

    Notes: An equation using only easily determined physical properties of particles has been developed for calculating the slip velocity of nonspherical particulate solids falling in fluid media in the intermediate flow range where neither the Stokes nor Newton law applies. The variation in Reynolds numbers covered by this work ranged from 12 to 460. Slip velocities calculated from the equation differed from experimental data by an average deviation of only 3.7% when solids of a wide range of diameters (156 to 1,247 microns), densities (71 to 475 lb./cu. ft.), surface shape factors (0.40 to 0.97), and gases of a wide density range (0.01 to 0.31 lb./cu. ft.) were utilized. Thirty-eight different gas-solid systems were studied.
