Published 1983Staff ViewISSN: 1750-3841Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionProcess Engineering, Biotechnology, Nutrition TechnologyNotes: Compositional analysis data for 47 whey powders (including sweet whey, acid whey, demineralized delactosed whey and whey protein concentrates) were correlated with near infrared reflectance (NIR) measurements. The most useful wavelengths for determining constituent concentrations were chosen from 19 pre-selected wavelengths by using linear regression analysis. Results indicate that samples to be used for NIR calibrations should be similar in composition and should represent a limited range of constituent concentrations. Individual NIR calibrations need to be developed for each type of whey powder to be analyzed.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-9125Source: Springer Online Journal Archives 1860-2000Topics: MathematicsNotes: Abstract We here study some problems concerned with the computational analysis of finite partially ordered sets. We begin (in § 1) by showing that the matrix representation of a binary relationR may always be taken in triangular form ifR is a partial ordering. We consider (in § 2) the chain structure in partially ordered sets, answer the combinatorial question of how many maximal chains might exist in a partially ordered set withn elements, and we give an algorithm for enumerating all maximal chains. We give (in § 3) algorithms which decide whether a partially ordered set is a (lower or upper) semi-lattice, and whether a lattice has distributive, modular, and Boolean properties. Finally (in § 4) we give Algol realizations of the various algorithms.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-601XSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Zusammenfassung Es wird gezeigt, daß der scheinbar mit einer Gleichstromspannung von weniger als 20 Volt in Helium brennende (abnorm niedervoltige) Lichtbogen dadurch zustande kommt, daß Schwingungen im Bogen vorhanden sind, die die Spannung an den Elektroden zeitweise bis auf über 20 Volt hinaufdrücken. Die in den Zeigerinstrumenten und Widerständen vorhandene Selbstinduktion der Apparatur ist zum Bestehen des Bogens notwendig, aber die Frequenz kann nicht aus der Thomsonschen Formel berechnet werden. Die Tonhöhe ist vielmehr noch von der Bogenstromstärke, der Heiztemperatur, dem Elektrodenabstand usw. abhängig.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-601XSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Zusammenfassung Auf den Ramanspektren vieler Flüssigkeiten ist noch ein kontinuierlicher Grund sichtbar. Es wird untersucht, ob dieses Kontinuum, das bei der Beobachtung senkrecht zum Einfallslicht meist vollständig depolarisiert ist, Ramanstrahlung darstellt. Hierzu wird geprüft, ob das Kontinuum bei Einstrahlung von zirkulär polarisiertem Licht und Beobachtung parallel zum Einfallslicht im umgekehrten Sinne zirkularpolarisiert ist wie der einfallende Lichtstrahl. Nur in diesem Falle kann nämlich nach der zuerst von Placzek aufgestellten Theorie das Kontinuum ein Ramaneffekt sein. Die Versuche werden an folgenden typischen, ausgewählten Beispielen von Flüssigkeiten, in denen ein starker kontinuierlicher Grund beobachtet wurde, ausgeführt: Benzol, Benzaldehyd, Glycerin, Schwefelsäure, Salpetersäure in verschiedenen Konzentrationen, Ameisensäure, Kalilauge, binäre Gemische von Methanol-Hexan und Methanol-Schwefelkohlenstoff im Temperaturgebiet der kritischen Opaleszenz. Das Kontinuum erweist sich in allen Fällen entweder als Fluoreszenzlicht oder als Rayleighstreuung des kontinuierlichen Grundes der Hg-Lampe in der Flüssigkeit, in keinem Falle aber als Ramanstrahlung. An einigen der untersuchten Flüssigkeiten (am eingehendsten an Benzaldehyd) wird gezeigt, daß der von der Theorie geforderte Zusammenhang zwischen der Depolarisation bei der Senkrechtbeobachtung und der Stärke der Umkehrung der Zirkularpolarisation bei der Farallelbeobachtung für das Ramanlinienspektrum so genau erfüllt ist, als die nur qualitativen Intensitätsschätzungen diese Prüfung gestatten.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-069XKeywords: Aged ; Contact sensitivity ; Langerhans cells ; Interleukin-2 ; Interferon-γSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary Contact sensitivity responses were evaluated in young adult (3–5 months) and aged (16–26 months) BALB/c mice which were systemically treated with interleukin-2 (IL-2), interferon-γ (IFN-γ) or saline. Mice older than 16 months of age have deficient numbers of Ia+ Langerhans cells in addition to their well-known impaired T cell functions. They also have an impaired cell-mediated response to contact sensitization with 1-chloro-2,4,6-trinitrobenzene. This hyporesponsiveness in aged mice can be almost completely reversed by ness in aged mice can be almost completely reversed by IL-2 and is marginally improved by IFN-γ. Exposure of skin from aged mice to interleukin-2 or interferon-γ, both in vivo and invvitro, causes increases in the density of Ia+ Langerhans cells to levels approximating those in young mice. Since IFN-γ causes partial restitution while IL-2 fully restores the contact hypersensitivity in aged animals, we conclude that the hyporesponsiveness in aged mice results both from defective Ia antigen expression on the antigen-presenting Langerhans cells and from deficient T cell function.Type of Medium: Electronic ResourceURL: -
