   Sammanfattning : Photodynamic therapy, PDT, is a method to diagnose and treat cancer. In PDT a sensitizer is administered to the patient and this sensitizer is accumulated in tumors. If the sensitizer-containing tumor is subjected to a laser of a specific wavelength the tumor is fluorescing allowing diagnostics. LÄS MER

   Sammanfattning : The main purpose of this thesis was to find ways to maintain a low level of light‐induceddiscolouration at an increased addition of mechanical and chemimechanical pulps in coated highqualityfine paper and magazine paper grades. Current technology allows the production of highyieldpulps such as thermomechanical and chemimechanical pulps with properties suitable formanufacturing high‐quality paper or paperboard with a low basis weight.
