  1. 1. Precipitation and separation of lignin from kraft black liquor

    Författare :Fredrik Öhman; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pressing; filtration; washing; lignin; separation; precipitation; black liquor; extraction;

    Sammanfattning : The separation of lignin from black liquor is an attractive option to consider for pulp mills. In modern pulp mills, lignin extraction offers the opportunity of withdrawing an energy surplus in the form of a solid biofuel. LÄS MER

  3. 3. Climate Change Adaption of Waterworks for Browning Surface Waters : Nano- and Ultrafiltration Membrane Applications for Drinking Water Treatment

    Detta är en avhandling från Water Resources Engineering, Lund University

    Författare :Alexander Keucken; Lunds universitet.; Lund University.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural organic matter NOM ; drinking water; ultrafiltration; nanofiltration; autopsy; modelling;

    Sammanfattning : Natural organic matter (NOM) is found in all surface, ground, and soil waters. During recent decades, reports worldwide show a continuing increase in the color and NOM of the surface water, which has an adverse effect on drinking water purification. For several practical and hygienic reasons, the presence of NOM is undesirable in drinking water. LÄS MER

  4. 4. Erythrocyte deformability studies by viscometry and filtrometry

    Detta är en avhandling från Lund, Sweden : Lunds Universitet

    Författare :Sylvi Persson; [1994]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Erythrocyte deformability; viscometry; Filtrometry; Red cell membrane; Buffer; Filtration pressure; stress factors; Mean corpuscular volume; Sodium-potassium pump; Ouabain; Corticosteroids; Blood storage; Transfusion; MEDICINE; MEDICIN;

    Sammanfattning : DOCTORAL DISSERTATION AbstractThe present thesis concerns factors of major importance in filtrometric studies of human erythrocytes, e.g. influence of buffer media, importance of filtration pressure for filtration through micropores and possible effects of damaged and hemolyzed blood cells.

  5. 5. Nephrotic syndrome in children : Functional, morphological and therapeutical aspects

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Surgical Science

    Författare :Eva Löwenborg; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Children; glomerular volume; glomerular filtration rate; effective renal plasma flow; rats; nephrotic syndrome; cyclosporine; nephrotoxicity;

    Sammanfattning : Although cure rates of the idiopathic nephrotic syndrome in children have improved because of advances in immunosuppressive therapy, the pathogenesis and course of the disease remain controversial. We have followed children with nephrotic syndrome to study renal function and morphological changes in kidney biopsies and in an experimental study. LÄS MER
