  4. 3. Urodynamic modelling and measurement techniques for assessment of urethral function during micturition

    Författare :Heikki Teriö; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : According to Griffiths' theory of flow through elastic tubes the urinary flow is controlled by an elastic constriction. The mechanical properties of this flow-controlling zone are described by the intrinsic urethral pressure as a function of cross-sectional area given by the pressure/area relation p(A)=pmo + KnAn, where pmo is the minimal urethral opening pressure, A the cross-sectional area and Kn and n are parameters describing the distensibility of this zone.

  5. 4. Ion recombination in liquid ionization chambers : development of an experimental method to quantify general recombination

    Författare :Jonas Andersson; Heikki Tölli; Lennart Johansson; Anders Ahnesjö; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General recombination; initial recombination; liquid ionization chamber; radiation dosimetry; radiofysik; radiation physics;

    Sammanfattning : An experimental method (the two-dose-rate method) for the correction of general recombination losses in liquid ionization chambers has been developed and employed in experiments with different liquids and radiation qualities. The method is based on a disassociation of initial and general recombination, since an ionized liquid is simultaneously affected by both of these processes. LÄS MER

  7. 5. Holocene Climate in Central and Southern Sweden : Quantitative Reconstructions from Fossil Data

    Författare :Karin Antonsson; Keith Bennett; Heikki Seppä; Andy Lotter; Uppsala universitet; []
    Nyckelord :Quaternary geology; pollen analysis; climate reconstructions; transfer functions; vegetation dynamics; Sweden; Kvartärgeologi;

    Sammanfattning : In quantitative palaeoecology modern species-environmental relationships can be statistically modelled, and recent development has made the calibration models more statistically robust. These models are used to transform fossil assemblages to quantitative estimates of past environmental conditions. LÄS MER
