  3. 3. Ecotoxicological classification of ash materials

    Författare :Sara Stiernström; Magnus Breitholtz; Christina Rudén; David Bendz; Olof Berglund; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ecotoxicity; ash; classification; leaching; Waste Framework Directive; CLP-Regulation; Hazard Identification; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. LÄS MER

  4. 4. Molecular Classification of Bladder Cancer

    Författare :Gottfrid Sjödahl; Bröstca-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bladder cancer; Subtype; Classification;

    Sammanfattning : Decisions in the treatment of bladder cancer today are based on clinical and pathological risk variables such as tumor stage and tumor grade. The importance of these conventional risk variables is well documented since more than 10 years, and they are used routinely in the clinics. LÄS MER
