    Systematic and statistical errors in correlation estimators obtained from various digital correlators (1999)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A number of commercially available digital correlators is discussed with respect to algorithms, systematic errors, and statistical errors. Special attention has been paid to the determination of an influence of the temporal integration of measured signals on autocorrelation functions measured in digital correlators. A calculation of the standard deviation for statistical errors in correlation estimators has been performed. The result is compared with the experiment. Favorable noise properties of the multiple-tau correlator which have been reported in the literature are not confirmed. © 1999 American Institute of Physics.

    Observation of ballistic carrier propagation in Bi and W by scanning electron microscopy (1999)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 85 (1999), S. 276-279

    Notes: A scanning electron microscope with cryogenic sample holder has been employed for spatially resolved excitation of carriers. A point contact at a fixed position on the sample surface opposing the area scanned by the electron beam serves as a local current probe. Ballistic propagation and focusing of electron beam excited carriers is observed in single crystalline high purity samples of bismuth and tungsten over distances of typically 100 μm. Signal contributions from diffusive carrier flow as well as ballistic phonons are observed in addition to the ballistic electron signals. © 1999 American Institute of Physics.

    Rotational Brownian motion of solute fluorescent molecules in liquids: Theory and experiment (1995)

    Notes: Abstract The theories for the rotational Brownian motion of molecules in liquids were experimentally verified on the example of selected fluorescent probe molecules dissolved in various solvents. Agreement between theories and experimental results as well as some disagreements between them were found. The model of a “coloured noise” random torque has been employed to diminish the discrepancy between the Hubbard-Morita model of rotational Brownian motion of molecules in liquids and the experimental data. A “mass drag” effect due to the existence of viscosity shear waves is taken into account in the explanation of inertial effects in molecular motion in liquids. The hypothesis of microviscosity has been confirmed in some experimental situations.

    Notes: Abstract A focusing transducer based on a 9-µm thick PVDF foil was fabricated and tested for performance. The transducer operates in the frequency range of 20–160 MHz. For operation at 78 MHz in water, a lateral resolution of 27.5 µm and a vertical resolution of 35 µm have been observed. Acoustic images of a transistor have been obtained with the focusing PVDF transducer.

    Notes: Zusammenfassung Mit Ausnahme der nach Pneumonien und Infarkten auftretenden Lungenabscesse werden alle übrigen Lungeneiterungen entsprechend ihrer Ätiologie zusammengestellt und an Hand einiger Beispiele hinsichtlich der Klinik und Therapie besprochen. Es erscheint dies notwendig, da sich hinter dem meist einheitlichen Symptomenbild der subakuten bis chronischen Lungeneiterung recht unterschiedliche Krankheitsursachen verbergen. Diese Ursachen teilen sich im wesentlichen auf in Bronchusverschluß, sei es durch einen Tumor oder durch Fremdkörperaspiration, in angeborene Veränderungen des Lungenparenchyms und der Bronchien, in oesophago-pulmonale Fisteln und Pilzerkrankungen. Bei diesen Erkrankungen steht fast ausschließlich die operative Behandlung im Vordergrund. Die angeführten Beispiele sind einem Krankengut von 138 Fällen entnommen.

    Zur Anwendung eines extrakorporalen Umgehungskreislaufes für Operationen an der descendierenden thorakalen Aorta (1960)

    Notes: Zusammenfassung Die Erfahrungen an 4 klinischen Beobachtungen — 3 Aneurysmen und 1 perforierende Verletzung bei einer Ductus Botalli-Operation —zeigen, daß ein By-pass vom linken Vorhof zur A. femoralis unter Verwendung einer Pumpe eine relativ einfache Methode zur Kompensierung eines Verschlusses der descendierenden thorakalen Aorta darstellt. Da kein Oxygenator, sondern nur eine Pumpe benötigt wird, können die entsprechenden Schläuche, Katheter und Ansatzstücke steril aufbewahrt und zum sofortigen Gebrauch im Operationssaal bereitgehalten werden (Fall 4). Das extrakorporale System kann mit weniger als 500 cm3 Blut oder einer Blutersatzlösung gefüllt, die Möglichkeit einer Luftembolie praktisch ausgeschlossen werden. Das Einschalten eines Blutreservoirs in den extrakorporalen Kreislauf sowie die Möglichkeit, das heparinisierte Blut des Operationsfeldes direkt in das System zurückzusaugen, bieten einen ausgezeichneten Schutz gegen massive Blutungen, wie sie gerade bei ausgedehnten Aortenaneurysmaoperationen entstehen können (Fall 2).

    Untersuchungen über die instrumentelle Gallengangsexploration (1961)

    Notes: Zusammenfassung An 20 Hunden wurden die Folgen der instrumentellen Gallengangsrevision mikroskopisch untersucht. Hierbei zeigt sich, daß vorsichtige und sorgfältige Manipulationen keine nennenswerten Läsionen im Bereich des Choledochus und der Papille hervorrufen. Bei stärkerer mechanischer Schädigung (Schaben mit dem Gallensteinlöffel) kommt es zu ausgedehnten Epitheldefekten, erheblicher entzündlicher zündlicher und hämorrhagischer Überschwemmung. Das Bougieren der Papille führt zu den gleichen Veränderungen: Epitheldefekte, hämorrhagische und entzündliche Imbibition. Die stärksten Veränderungen werden beim Sprengen der Papille ausgelöst. Die Schäden sind teilweise so schwer, daß der normale Aufbau des Diverticulum duodeni nicht mehr erkennbar ist. Vereinzelte Befunde lassen es als möglich erscheinen, daß sich im Verlauf von 2–3 Wochen auch mittelschwere Schädigungen zurückbilden. Eine endgültige Stellungnahme hierzu ist wegen der geringen Zahl der untersuchten Fälle nicht möglich.
