  1. 1. Association Phenomena in Aqueous Solutions of Surfactants and Hydrophobically Modified Polymers

    Författare :Susanne Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self-diffusion; rheology; cellulose ethers; associating polymers; polymer-surfactant interactions; polymer network; Fysikalisk kemi; Physical chemistry;

    Sammanfattning : Interactions between ionic surfactants (sodium dodecyl sulfate and dodecyltrimethylammonium chloride) and nonionic polymers ((hydroxyethyl)cellulose, ethyl(hydroxyethyl)cellulose and their hydrophobically modified analogous) have been studied by means of rheology, pulsed field gradient nuclear magnetic resonance (PFG NMR), time-resolved fluorescence quenching (TRFQ), dynamic light scattering (DLS) and cryo-transmission electron microscopy (cryo-TEM). In all experiments surfactants have been added in various amounts to polymer solutions at fixed concentrations. LÄS MER

  3. 2. Making innovation everyone´s business : Using routines and controls

    Författare :Susanne Nilsson; Sofia Ritzén; Antonio Davila; KTH; []
    Nyckelord :;

    Sammanfattning : Contemporary high-technology companies are under pressure to deliver short-term profits and to serve the market demands for future innovative solutions. An increased interest for alternative innovations such as new services or business models to be recognized in parallel to new technologies results in that companies are increasingly attempting to engage all their employees in innovation.

  4. 3. The Effect of Crosslinking on Morphology and Electrical Properties in LDPE Intended for Power Cables

    Författare :Susanne Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LDPE; morphology; electrical treeing; peroxide; crosslinking; XLPE; water treeing;

    Sammanfattning : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is often made by peroxide initiated crosslinking of low density polyethylene (LDPE). The introduction of unsaturations, i.e. LÄS MER

  5. 4. The Effect of Crosslinking on Morphology and Water Treeing in LDPE

    Författare :Susanne Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water treeing; peroxide; network structure; crosslinking; morphology; LDPE;

    Sammanfattning : Crosslinked polyethylene (XLPE) is used as underground cable insulation due to its outstanding electrical properties and high temperature dimension stability. XLPE is made by peroxide initiated crosslinking of low density polyethylene. In recent years, polyethylene with unsaturations, i.e. LÄS MER

  7. 5. Anxiety among Adolescents : Measurement, Clinical Characteristics, and Influences of Parenting and Genetics

    Författare :Susanne Olofsdotter; K.W. Nilsson; Tomas Furmark; Mats Humble; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescent; anxiety; assessment; prevalence; comorbidity; parenting; oxytocin; gene–environment interaction; differential susceptibility; Child and Youth Psychiatry; Barn- och ungdomspsykiatri;

    Sammanfattning : Anxiety is the most commonly reported mental health problem among adolescents. Still, many adolescents in need of treatment are not detected and the clinical characteristics and etiological pathways of adolescent anxiety are under-researched topics. LÄS MER
