    Författare :Johan Berglund; Joel Kullberg; Lars Johansson; Håkan Ahlström; Zhi-Pei Liang; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Magnetic resonance imaging; digital image reconstruction; chemical shift imaging; water and fat separation; Dixon method; fat suppression; quantitative MRI; whole-body MRI; fatty acid composition; fat unsaturation; triglycerides; adipose tissue; liver fat; T2* mapping; Radiology; Radiologi; Radiology; Radiologi;

    Sammanfattning : Magnetic resonance imaging (MRI) is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. LÄS MER

  4. 3. Livets dubbla vedermödor : Om moderskap och arbete

    Författare :Maria Jansson; Maud Eduards; Marja Keränen; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; feminist theory; motherhood; labour; citizenship; daycare policies; Sweden; Political science; Statsvetenskap; statsvetenskap; Political Science;

    Sammanfattning : There are conflicts between waged labour and motherhood that make it difficult for women to seize independence as workers and at the same time be mothers. These conflicts manifest themselves in women’s everyday practices as well as in feminist theory and in the women’s movement. LÄS MER

  5. 4. Advances in Separation Science : . Molecular Imprinting: Development of Spherical Beads and Optimization of the Formulation by Chemometrics

    Författare :Henrik Kempe; Anders Colmsjö; Ulrika Nilsson; Jan Åke Jönsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatography; Parameter estimation; Diffusion; Molecularly imprinted polymer; Suspension polymerization; Chemometrics; Analytical chemistry; Analytisk kemi;

    Sammanfattning : An intrinsic mathematical model for simulation of fixed bed chromatography was demonstrated and compared to more simplified models. The former model was shown to describe variations in the physical, kinetic, and operating parameters better than the latter ones. LÄS MER

  7. 5. Lignin Exraction from Black Liquor: Precipitation, filtration and washing

    Författare :Henrik Wallmo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Lignin; Filtration; Separation; Black liquor; Precipitation; Washing.; Absorption;

    Sammanfattning : Lignin extraction is a very interesting option for pulp mills today. Lignin is one major component, present as a dissolved organic compound, in black liquor, which is a by-product in the alkaline pulping of wood. After the digestion of wood chips, the black liquor is separated from the cellulose. LÄS MER
