    Selective grey level digitization of video images to analyze upper urinary tract dynamics (1988)

    Notes: Summary A method is presented to analyze video recordings of the dynamics of the upper urinary tract. Peristaltic fluid movements are visualized after surgical exposure of the rat ureter. Optical information is recorded through an operating microscope and stored on tape. The computer system reads and analyzes grey-levels upon user-defined measuring lines. One program is especially designed to measure the urine bolus length. The second program determines diameters at 20 equally distributed lines across the ureter. Data are displayed in two- or three-dimensional graphs, time-distance diagrams or series of rough drafts showing the changes of ureteral shape. Numeric values of measured parameters (bolus length and velocity, ureter diameter at 20 lines) can be listed. Diagrams of normal ureteral peristalsis and drafts of contraction-induced changes in ureteral shape (diameters) during acute distal obstruction are explained.

    Measurements ofβ-endpoint-energies using a magnetic electron separator (1992)
    Springer
    The European physical journal 342 (1992), S. 23-26

    Notes: Abstract Beta endpoint energies of the short-lived neutron rich fission products90,91,92,93,94,95,96,97,98,Rb have been measured using a newly constructed achromatic magnetic electron-separator that eliminates low energy electrons. Thus only electrons in the neighbourhood of theβ-endpoint are recorded in a low background environment.

    Notes: Abstract In continuation to ourβ-endpoint measurements of shortlived Rb-isotopes at ISOLDE we have determined preciseβ-endpoint energies of139,140,141,142,143,144,145,146Cs using our achromatic magnetic electron separator that eliminates low energy electrons. Here only electrons in the neighbourhood of theβ-endpoint are recorded in a low background environment.
