    Notes: Abstract Within the Jet Propulsion Laboratory in Pasadena, California, state of the art computer graphics animation is done in the Computer Graphics Laboratory. The topics of the animations cover many scientific disciplines. Specific features of the system developed there, both hardware and software, are discussed. The prime mover of the effort is Dr. James F. Blinn of Pasadena; his role and experiences are elaborated. Their current largest project is The Mechanical Universe; the system is used for its production.

    Description / Table of Contents: Zusammenfassung QuarternäreHeusler-Legierungen der Zusammensetzung (Ni1−x Cu x )2MnSn wurden über den Konzentrationsbereichx=0–1 hergestellt. Alle waren einphasig und zeigten L 21-Struktur. Magnetische Messungen wurden sowohl im ferromagnetischen als auch im paramagnetischen Bereich durchgeführt. Sie ergaben für Mn, das einzige Atom das in dieser Art vonHeusler-Legierungen ein Moment zeigt, den üblichen Wert von ca. 4 µB und ein ihm entsprechendes μeff im paramagnetischen Bereich. Ein flaches Minimum derCurietemperatur kann mit Hilfe von di-dl-Wechselwirkung erklärt werden.
    Notes: Abstract QuarternaryHeusler alloys of composition (Ni1−x Cu x )2MnSn were prepared withx=0–1. They were all single phased with L21 structure. Alloys were investigated by magnetic measurements. For Mn, the only atom carrying a moment in this kind ofHeusler alloys, the usual value (∼4 µB) was found and a corresponding μeff in the paramagnetic region. A shallow minimum of theCurie temperatures can be explained on the basis of di-dl interaction.

    A geophysical approach to the granite batholith under the eastern Southern Uplands, Scotland (1982)
    Springer
    Pure and applied geophysics 120 (1982), S. 375-388 
    Details
    ISSN: 1420-9136
    Keywords: Gravity ; Magnetism ; Scotland

    Topics: Geosciences , Physics
    Notes: Abstract From our interpretation of the Bouguer gravity and aeromagnetic anomalies in south-east Scotland, we conclude that a massive granite batholith underlies the greater part of the eastern Southern Uplands. The granite model which we computed earlier from gravity anomalies in the Tweeddale area fits the observed magnetic anomalies closely, if a normal magnetization of 0.095 A m−1 is assigned, similar to values found for exposed local granites. Further gravity modelling shows that, apart from the Tweeddale boss, the granite shallows to less than 1 km near Lammer Law in East Lothian and extends north of the Lammermuir Fault. A model for the East Lothian volcanics was computed from their aeromagnetic anomalies, then their gravitational effect was combined with that estimated for the Devonian and Carboniferous sediments and the result stripped off the observed gravity field. The residual gravity anomalies were used to generate a two-dimensional model for the granite north of the Lammermuir Fault. The expected tectonic consequences of a massive granite batholith in the eastern Southern Uplands are compared with the known development of faults and sedimentary basins around its margins.

    MINDO/SR calculations of nickel surface properties as a function of hydrogen coverage (1988)

    Topics: Chemistry and Pharmacology
    Notes: Abstract The MINDO/SR method is used to study surface properties such as the work function, heat of adsorption and magnetic moment as a function of hydrogen coverage. A good correlation between theory and experiment is found. Furthermore, a qualitative analysis of surface geometry changes due to hydrogen chemisorption is presented.

    Calcium phosphates in pharmaceutical tableting (1993)

    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Ten commercially available calcium phosphates used for direct tableting were evaluated. The particle size distributions, powder properties, Sorption isotherms and pH values of aqueous slurries were compared. All samples showed good or at least sufficient flowability. Scanning electron micrographs illustrated the different kinds of manufacturing and gave hints on their expectable behaviour under compaction pressure. The sorption isotherms of identical chemical substances, which had been manufactured by different methods, differed strongly. This can be related to their specific surface areas. Most of the hydroxylapatites have large surface areas and can absorb up to more than 15% water at 93% relative humidity. Dibasic calcium phosphate dihydrate was non-hygroscopic and absorbed less than 1% water. With the exception of monobasic calcium phosphate monohydrate all calcium phosphates behaved quite neutral in water. Monobasic calcium phosphate monohydrate can be regarded as a solid acid. Although the calcium phosphates are usually stable substances, the role of crystal water in the case of dibasic calcium phosphate dihydrate and monobasic calcium phosphate monohydrate is problematic due to possible interactions with active ingredients.
