  4. 3. Grundvatten i Uppsalatrakten

    Författare :Jan Sidenvall; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : I Uppsalatrakten utförda geologiska undersökningar redovisas i några profiler. Fem av dessa är tvärprofiler genom Uppsalaåsen. De visar, att åsen uppenbarligen följer en förkastning från Flottsund i söder till Gamla Uppsala i norr. Åsens kärna ligger på den mot öster vettande förkastningsbranten. LÄS MER

    Sammanfattning : The Jurassic and Early Cretaceous selachian faunas of Scania (Skåne), southern Sweden and the island of Bornholm (Denmark) have been investigated. Three Early Jurassic shark tooth assemblages have been recorded and investigated, one from Hettangian strata and the other two from Pliensbachian sediments. LÄS MER

  7. 5. Radioluminescence : A simple model for fluorescent layers - analysis and applications

    Författare :Jan Lindström; Åsa Carlsson Tedgren; Eva Lund; Michael Sandborg; Ioannis Kandarakis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : A phosphor or scintillator is a material that will emit visible light when struck by ionising radiation. In the early days of diagnostic radiology, it was discovered that the radiation dose needed to get an image on a film, could be greatly reduced by inserting a fluorescent layer of a phosphor in direct contact with the film.
