  1. 16. Slurry rheology of industrial minerals and its effects on wet ultra-fine grinding

    Författare :Mingzhao He; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : This thesis investigates slurry rheology of industrial minerals (limestone and quartzite) and its effects on wet ultra-fine grinding in order to reduce energy cost, increase the throughput as well as the product fineness. The influences of solid concentration, molecular weight of a dispersant, and particle size and distribution on the rheological behaviour of original limestone slurries have been investigated.

  3. 17. Ocean Climate Variability over Recent Centuries Explored by Modelling the Baltic Sea

    Författare :Daniel Hansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; ocean climate; modelling; reconsstruction; water temperature; sea ice; river runoff; salinity; oxygen concentration; long-term;

    Sammanfattning : Natural variability and anthropogenic factors both contribute to changes in the ocean climate of the Baltic Sea. Observations over the past century indicate that changes in environmental settings and ocean climate have taken place, attracting considerable media attention and building public awareness of climate and environmental issues related to the Baltic Sea.

  4. 18. Pharmacological and analytical studies of the cyclin dependent kinase inhibitors

    Författare :Hatem H A Sallam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cyclin-dependent kinases (Cdks) play a key role in the regulation of cell cycle progression and RNA transcription. Deregulation of Cdks has been associated with several malignancies, neurodegenerative disorders, viral and protozoal infections, glomerulonephritis and inflammatory diseases. LÄS MER
