    Space and time resolved temperature measurements in laser pulse-produced metal melts (1997)

    Notes: A fast broadband pyrometer with a spatial resolution of 2 μm and an accuracy of 10% in temperature is described plus a calibration method suitable for liquid metals. The time resolution of temperature measurements is limited by the electronics rise time (3.5 ns) to 14 ns (10%–90% rise time) of a temperature change because of the nonlinear relation between electronic signal and temperature. The pyrometer was applied to determine the temperature of melts produced by focused nanosecond laser pulses in gold and iron films. Measured heating rates (1010–1011 K/s) and peak temperatures (3000 K) are correctly reproduced by numerical simulations for gold, but theoretical peak temperatures in iron were 1000 K in excess. The low actual temperature in iron can be explained by native oxides, decomposing during the laser pulse and thus dissipating energy. This effect may cause considerable differences between computed and actual temperatures during laser processing of thin metal films with unstable impurities. © 1997 American Institute of Physics.

    Pulsed mirror electron microscope: A fast near-surface imaging probe (2001)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A pulsed mirror electron microscope was developed for imaging laser-induced processes on the nanosecond time scale. Variations of the electronic structure of the surface are imaged. The evaporation or deposition of an atomic monolayer is readily detected. Pulsed mirror electron microscopy is an alternative technique to pulsed photoelectron microscopy for tracking chemical reactions. In addition, gas flow above the surface and laser-induced ablation of absorbing layers at the back surface of a dielectric can be probed, exploiting electron scattering and capacitive coupling, respectively. Presently, the space/time resolution is limited by the competition between electron shot noise and illumination aperture to 1 μm/5 ns. The illuminating electron pulses are supplied by a laser-driven robust ZrC-covered Re cathode. This device can be operated in a high vacuum of 10−5 mbar either as a photo or a thermal electron emitter. © 2001 American Institute of Physics.

    Über primäre und subprimäre Mittelohrtuberkulose (1943)
    Springer

    Notes: Zusammenfassung 1. Es wurden bisher 36 Fälle von sicher primärer Mittelohrtuberkulose beschrieben, von denen Verfasser 21 beobachtet hat. 2. Alle sichergestellten Fälle betreffen das Säuglingsalter. 3. Der klinische Symptomenkomplex ist durch Ohreiterung, Tuberkelbazillen im Ohreiter, verkäsende Tuberkulose der regionären auriculären und cervicalen, insbesondere präauriculären Drüsen, vielfach auch Facialisparese charakterisiert. 4. Von den beschriebenen 36 Kindern sind 22 gestorben, zumeist infolge Generalisierung der Tuberkulose. 5. Schwere Folgeerscheinungen, Schwerhörigkeit bzw. Taubheit sind in jedem Falle zu erwarten. 6. Subprimäre Mittelohrtuberkulose bei Primärinfekt im Nasen-Rachenraum oder an den Gaumentonsillen ist durch anatomische Untersuchungen ebenfalls erwiesen. 7. Das klinische Bild ist weniger charakteristisch und mit chronischer unspezifischer Otitis zu verwechseln. 8. Ist durch Tuberkulinreaktion die Tuberkuloseinfektion des Säuglings erkannt, so muß die Differentialdiagnose durch ausgiebige und wiederholte bakteriologische Untersuchung des Ohreiters geklärt werden.

    Icterus Neonatorum Gravis (1930)

    Notes: Zusammenfassung 1. Unter Icterus gravis neonatorum verstehen wir eine vielfach familiär auftretende Erkrankung, die gewöhnlich innerhalb weniger Tage zum Tode führt, nur selten spontan überwunden wird. 2. Eine Abgrenzung gegenüber anderen schweren Ikterusformen der Neugeborenenzeit ist durch den morphologischen Blutbefund möglich, der in erster Linie durch eine hochgradige Erythroblastose charakterisiert ist. 3. Das Vorhandensein von reichlich Hämatin im Blutserum sowie die hochgradige Siderosis der verschiedensten Organe spricht für toxischen Blutzerfall. 4. Der Ikterus ist, wie sich aus der Serumuntersuchung nachvan den Bergh und dem Vorhandensein von gelöstem Bilirubin im Harn ergibt, teils dynamisch, teils mechanisch zu erklären. 5. Frühzeitige Bluttransfusion erscheint geeignet, die schweren Krankheitserscheinungen zu bessern und die Heilung anzubahnen.
