   Sammanfattning : Public services, such as education and health care, are provided by both public and private actors. In some countries, such as Sweden, these include for-profit organizations. In systems allowing the users to choose freely, the providers must compete, often by offering qualities that the users may care about. LÄS MER

3. 17. Volume imaging of the abdomen : three-dimensional visualisation of tubular structures in the body with CT and MRI

   Författare :Anders Persson; Örjan Smedby; Håkan Ahlström; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The overwhelming amount of image-based information in modem medicine makes it crucial to develop methods to handle and analyze images and make them comprehensible for users. The aim of this thesis was to study the radiological practice of three-dimensional (3D) visualization of tubular structures in the body with CT and MRI. LÄS MER

4. 18. The accessibility and chemical activity of polycyclic aromatic hydrocarbons in soil
