    Sammanfattning : The thesis is concerned with the problematic question on how to manage complex environmental risks in a way that promotes sustainable development. While there are some positive signs on progressive and successful environmental policy, environmental change resulting from human activities still causes severe problems and risks worldwide. LÄS MER

  4. 4. A study of some energy dependent characteristics of X-ray screens used in diagnostic radiology screen-film sensitivity, MTF and some related factors

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Mikael Karlsson; Umeå universitet.; [1983]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensifying screens; x-ray screens; fluorescent screens; modulation transfer function; MTF; x-ray screen sensitivity; fluorescent K-radiation sources;

    Sammanfattning : Fluorescent x-ray screens are used in medical x-ray diagnostics to absorb x-ray photons and convert these x-ray photons to visible light. The light distribution from these screens are then registered on photographic film to give an x-ray image. LÄS MER
