    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 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

  4. 4. Barriers to change? : understanding the institutional hurdles in the Russian forest sector

    Författare :Mats-Olov Olsson; Luleå tekniska universitet; []

    Sammanfattning : The ongoing transformation of the Russian society largely consists in changes in the institutional framework constraining actors' behavior in the emerging market economy. While we have a substantial knowledge about the functioning of a market economy we know very little about how to create such a system. LÄS MER

  5. 5. 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 :NATURAL SCIENCES; NATURVETENSKAP; 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
