  3. 2. Radioluminescence : A simple model for fluorescent layers

    Författare :Jan Lindström; Eva Lund; Michael Sandborg; Gudrun Alm-Carlsson; Linköpings universitet; []
    Nyckelord :Extrinsic efficiency; extinction factor; radioluminescence; modelling; Monte Carlo; optical attenuation; optimisation; particle size; phosphor; scintillator; MEDICINE; MEDICIN;

    Sammanfattning : The aim of this thesis is to present a simple model for the radiation to light conversion processes in fluorescent layers as an aid in future developments and applications. Optimisation between sensitivity and spatial resolution for fluorescent layers in digital radiology is a delicate task where the extrinsic efficiency for various phosphors needs to be established for varying parameters.

  4. 3. Housing tenure and residential mobility in Stockholm 1990-2014

    Författare :Andreas Alm Fjellborg; Roger Andersson; Jan Amcoff; Eva Andersson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Residential mobility; Housing tenure; Stockholm; Social and Economic Geography; Kulturgeografi;

    Sammanfattning : In this thesis the links between housing tenure, income and selective, segregation generating, residential mobility are explored. The development of these links is analysed against the background of housing regime changes in Stockholm between 1990 and 2014. LÄS MER

  5. 4. Calibration of Ionization Chambers for Measuring Air Kerma Integrated over Beam Area in Diagnostic Radiology

    Författare :Peter Larsson; Gudrun Alm Carlsson; Jan Persliden; Bertil Axelsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; KAP-meter; DAP-meter; PKA; kerma area product; energy dependence; calibration; Radiological physics; Radiofysik;

    Sammanfattning : The air kerma area product PKA is an important quantity used by hospital physicists in quality assurance and optimization processes in diagnostic radiology and is recommended by national authorities for setting of diagnostic reference levels. PKA can be measured using a transmission ionization chamber (kerma area product (KAP) meter) mounted on the collimator housing. LÄS MER

  7. 5. “It was like I had to fit into a category” : people with trans experiences navigating access to trans-specific healthcare and health

    Författare :Ida Linander; Lisa Harryson; Isabel Goicolea; Anne Hammarström; Erika Alm; Jan Wickman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transgender; Gender dysphoria; Qualitative; Access to healthcare; Health inequalities; Affective labour; Trans studies; Queer phenomenology; Foucault; Governmentality; Sex reassignment; folkhälsa; Public health; gender studies; genusvetenskap;

    Sammanfattning : Background: Trans issues have received increased attention over the last couple of years and important changes have been made in the legislation relating to gender reassignment and in trans-specific healthcare practices. At the same time, many people with trans experiences report poor mental health, bad experiences when encountering the healthcare and a tendency to postpone seeking care due to being badly treated.
