    Risk-sensitive foraging by a migratory bird (Dendroica coronata) (1986)
    Springer
    Cellular and molecular life sciences 42 (1986), S. 1054-1056 
    Details
    ISSN: 1420-9071
    Keywords: Bird migration ; foraging behavior ; risk-sensitivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Because migration is a period of exceptional energy demand, individuals in migratory disposition should be particularly sensitive to variability in food availability, i.e. show risk-sensitivity in their foraging behavior. When given the opportunity to feed at either a constant or a variable reward station, birds in migratory disposition (experimentals) chose the variable reward (risk-acceptance) more often than the constant reward during the premigratory fattening period as they gained weight and accumulated an energy reserve, while control birds not in migratory disposition consistently preferred the constant reward (risk-aversion). Once birds in migratory disposition attained maximum body weight and began to show nocturnal restlessness, their behavior changed and they, too, behaved in a risk-averse manner.

    Untersuchungen über das Rücksprühen bei der elektrischen Staubabscheidung (1959)
    Weinheim : Wiley-Blackwell
    Chemie Ingenieur Technik - CIT 31 (1959), S. 43-49 
    Details
    ISSN: 0009-286X

    Notes: Die Wirksamkeit elektrischer Entstaubungsanlagen wird durch das Rücksprühen (Rückionisation) bei der Abscheidung von Stäben mit extrem hohem elektrischem Widerstand herabgesetzt. Das Rücksprühen an Schichten elektrisch niedergeschlagenen Staubes bei 150 °C an Eisensulfat, Eisenoxyd, Zinkoxyd, Steinkohle, Braunkohle, Zement, Magnesiumoxyd und Flugasche wurde untersucht. Nach den Ergebnissen wird die Rückionisation durch hohen Staubwiderstand, hohe Stromdichte und geringe Schichtdicke des niedergeschlagenen Staubes begünstigt. Besonders kräftiges Rücksprühen ist z. B. an Schichten von etwa 0,2 mm Dicke von Stäuben, deren spezifischer Widerstand größer als 2 · 1012 Ohm cm ist, zu beobachten.

    Elektrostatische Feinstzerstäubung von Flüssigkeiten (1969)
    Weinheim : Wiley-Blackwell
    Chemie Ingenieur Technik - CIT 41 (1969), S. 503-507 
    Details
    ISSN: 0009-286X
    Keywords: Chemistry ; Industrial Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Die elektrostatische Zerstäubung von Flüssigkeiten ist auch oberhalb der im allgemeinen angegebenen Leitfähigkeitsgrenze von χ = 10-5 Ω-1 cm-1 noch möglich, wenn geeignete Zerstäubungselektroden verwendet und bestimmte Zerstäubungsbedingungen eingehalten werden. Als Zerstäubungselektroden eignen sich oberhalb dieser Grenze vor allem Ringelektroden und Zylinderelektroden mit besonderen Benetzungseinrichtungen für den Sprührand. In Luft ist eine hinreichend gute Zerstäubung nur an der positiven Elektrode möglich. Unter Frigen-Atmosphäre kann sowohl an der positiven wie an der negativen Elektrode bei verbesserter Ausbeute zerstäubt werden. Mit steigender Leitfähigkeit der Flüssigkeit fällt die in der Zeiteinheit zerstäubbare Menge stark ab, und der Tropfen-durchmesser wird kleiner. Für Leitfähigkeitswerte χ ≥ 1 ċ 10-4 Ω-1 cm-1 liegt die Tropfengröße unter 1 μm.
