    Notes: Abstract We determine in almost all Manhattan lattices configurations, which for specified diameter have maximal cardinality. Cases, in which those configurations are spheres, have been studied recently by Kleitman and Fellows. For Hamming spaces we present a partial result supplementing a result of Frankl and Füredi and we formulate a general conjecture.

    U/Pb-Datierung an Pechblenden und uranhaltigen Erzen aus den Uranlagerstätten von Taoshan, Südchina (1990)

    Description / Table of Contents: Abstract Pitchblende and uraniferous ore samples from the Taoshan uranium deposits were investigated by the U-Pb method. All data yielded discordant U-Pb ages which indicate a complex U-Pb evolution. Age calculations for the isochron method, the Tera-Wasserburg concordia model and the Pb-Pb isochron plane model gave identical results. The uranium mineralization took place about 70 Ma ago, equivalent to the thermal event at the end of Cretaceous. A further age of about 512 Ma is explained to indicate an episodic U-Pb differentiation at the end of Cambrian by the tectonometamorphism of uranium source in this region.
    Abstract: Résumé La méthode U/Pb a été appliquée à la pechblende et au minerai uranifère du gisement de Taoshan. Toutes les mesures ont fourni des âges U/Pb discordants, ce qui indique une évolution complexe de l'association U-Pb. Les calculs de l'âge, effectués par la méthode de l'isochrone, par le modèle Concordia de Tera-Wasserburg et par le modèle de la surface isochrone Pb-Pb ont donné des résultats sensiblement identiques. La minéralisation en uranium s'est effectuée il y a 70 Ma environ et correspond à un événement thermique de la fin du Crétacé. Un âge supplémentaire de 512 Ma est expliqué par une différenciation épisodique U-Pb à la fin du Cambrien, en relation avec l'histoire tectono-métamorphique des roches qui sont la source de l'uranium dans cette région.
    Notes: Zusammenfassung Pechblenden und uranhaltige Erze aus den Uranlagerstätten von Taoshan wurden mit der U/Pb-Methode untersucht. Alle Daten ergaben diskordante U/Pb-Alter und zeigen damit eine complexe U/Pb-Entwicklung. Altersberechnung mit der Isochronenmethode, dem Tera-Wasserburg Konkordia-Modell und dem Pb/Pb-Isochronenflächen-Modell ergaben nahezu übereinstimmende Ergebnisse. Die Uranmineralisation fand vor ungefähr 70 Ma statt und korrespondiert mit einem thermischen Ereignis am Ende der Kreide. Ein weiteres Alter von etwa 512 Ma läßt sich mit einer episodischen U/Pb-Differenzierung am Ende des Kambriums verursacht durch eine Tektonometamorphisierung der Uranlieferanten in diesem Gebiet interpretieren.

    Notes: Summary Information about the bursting strength of animal cells is essential if the mechanisms of cell damage in bioreactors are to be understood, and if cell mechanical properties are ever to be related to cell structure and physiology. We have developed a novel cell compression technique that makes it possible to directly measure the bursting strength of single mammalian cells, and to infer information about cell mechanical properties.

    Post-flare coronal loop interaction (1993)
    Springer
    Solar physics 148 (1993), S. 139-151 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract High-resolution images of post-flare loop systems in Fexiv (5303 Å) and Fex (6374 Å) display occasional transient enhancements at the projected intersection of some loops. The brightness of a green-line enhancement gradually increases to a marked maximum and then fades with a lifetime of the order of thirty minutes. The red-line image at the same location, although fainter, shows the same overall characteristics, its maximum following that of the green-line on average by 8.6 min. Hα then becomes more evident and reaches a maximum in extent on average 9.3 min after the red-line maximum. The phenomenon is interpreted as a process of localized loop coalescence involving partial magnetic reconnection. Estimates of the electron density are derived from the cooling time following the initial heating of the plasma in the immediate vicinity of the X-point of interaction. Similar estimates for the energy dissipated, equivalent to a very small flare, are derived by two independent methods.

    Probing palladium-cobalt/NaY catalysts by neopentane conversion (1992)
    Springer
    Catalysis letters 13 (1992), S. 123-130 
    Details
    ISSN: 1572-879X
    Keywords: PdCo/NaY ; zeolite catalysts ; bimetal catalysts ; cobalt ; palladium ; neopentane conversion ; catalytic isomerization of neopentane
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Neopentane conversion in hydrogen was used as a catalytic probe for zeolite encaged PdCo particles. Activity and selectivity strongly depend on the pretreatment conditions. PdCo/NaY catalysts exhibit higher isomerization selectivity than Pd/NaY in conformity with previous results on SiO2 supported Pd and PdCo. This is remarkable, because reduced Co/SiO2 displays 100% selectivity for hydrogenolysis. The isomerization selectivity thus appears to be a useful measure for the extent of alloying between Pd and Co.

    Notes: Abstract This work summarizes the progress in the study of the superconductor response to optical radiation and in the development of infrared detectors. The recent advances in the design of high-T c superconducting radiation detectors using silicon microfabrication technology are emphasized. Thermal and optical properties important for the detector performance are discussed. The mechanism of the nonequilibrium optical response and its potential use to build fast and sensitive radiation detectors are described. Future challenges and opportunities in the development of high-T c superconducting radiation detectors are highlighted.

    Notes: Abstract The IR and visible spectra of HPromazine+ deuteroreineckate−, DPromazine+ reineckate− and HPromazine+ reineckate−, reineckate− is Cr(NCS)4(NH3) 2 − are reported together with the X-ray crystal structure determination of the latter. The assignment of the IR bands and the visible spectra are discussed in conjunction with the X-ray data. There is extensive hydrogen bonding in crystalline HPromazine+ reineckate− and the influence of the hydrogen bonding on the dimensions of the reineckate− anion is discussed. The folding of the phenothiazine ring in various derivatives is analyzed.

    Walking, feeding and intraspecific interaction of larvae of Metaseiulus occidentalis, Typhlodromus pyri, Neoseiulus fallacis and Amblyseius andersoni held with and without eggs of Tetranychus urticae (1994)

    Notes: Abstract Larvae of Metaseiulus occidentalis (Nesbitt), Typhlodromus pyri Scheuten, Neoseiulus fallacis (Garman) and Amblyseius andersoni Chant exhibited different activity levels when held on apple leaf or on tile arenas and given or not given eggs of Tetranychus urticae Koch and water (tiles only). M. occidentalis larvae held without prey exhibited high levels of walking (includes searching) during 24 hours of evaluation, whereas M. occidentalis larvae held with prey fed quickly and then became less active. Fed larvae of M. occidentalis were less active on leaves than tile. Larvae of T. pyri on leaves had a very low frequency of walking, almost never fed and quickly assumed a resting position during development. While much less active than M. occidentalis, fed and unfed T. pyri larvae walked more on tiles than leaves before resting. Larvae of N. fallacis and A. andersoni fed at low rates and were similarly active on tiles and leaves. Free water increased walking by M. occidentalis, A. andersoni and T. pyri on tile but not N. fallacis. M. occidentalis larvae interacted 5–7 times more often than larvae of the other three species. Cannibalism or scavenging was rarely seen and then only for M. occidentalis larvae. Larvae of all four mites walked, fed and interacted much more in the first 12 hours than the second 12 hours of tests, except unfed M. occidentalis. Unfed M. occidentalis larvae did not molt to protonymphs but unfed larvae of the other three species did. Unfed and fed protonymphs of all four species walked more at 4 hours after molting than larvae at 12–24 hours. Unfed and fed protonymphs of T. pyri or A. andersoni had similar walking frequencies, but unfed protonymphs of N. fallacis were more active than fed ones. Trends in larval activities are discussed relative to the life history of each species.
