  1. 1. Nuclear Magnetic Resonance Spectroscopy and Spin Relaxation in Amphiphilic Liquid Crystals

    Författare :Stefan Gustafsson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Fysicumarkivet A:1997:Gustafsson;

    Sammanfattning : Spin relaxation theory and nuclear magnetic resonance spectroscopy in amphiphilic liquid crystals are presented. Group theory is used to determine the information content and the orientation dependence in spin relaxation experiments, and to investigate the combined effect of crystal and local symmetries and the effect of symmetry on multiple timescales.

  3. 2. Electromagnetic Dispersion Modeling and Analysis for Power Cables

    Författare :Stefan Gustafsson; Sven Nordebo; Alexander Nosich; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; power cable; electromagnetic model; dispersion relation; asymptotic analysis; sensitivity analysis;

    Sammanfattning : This thesis addresses electromagnetic wave propagation in power cables. It consists of five papers, where the three first papers are based on one and the same model, and the last two papers are based on a similar but slightly different model. LÄS MER

  4. 3. Adiponectin : genetic determinants and relations with subclinical cardiovascular disease

    Författare :Stefan Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :adiponectin;

    Sammanfattning : Cardiovascular disease (CVD) is a major cause of morbidity and premature death in Sweden and globally, which besides the substantial individual suffering, puts large restraints on the public health system. Adiponectin is a highly heritable trait, which is strongly associated with metabolic disturbances such as obesity and insulin resistance. LÄS MER

  5. 4. Electromagnetic dispersion modeling and analysis for HVDC power cables

    Författare :Stefan Gustafsson; Sven Nordebo; Martin Norgren; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HVDC power cables; electromagnetic model; TDR measurement; sensitivity analysis; dispersion relation; propagation constant; low-frequency asymptotics;

    Sammanfattning : Derivation of an electromagnetic model, regarding the wave propagation in a very long (10 km or more) High Voltage Direct Current (HVDC) power cable, is the central part of this thesis. With an existing “perfect” electromagnetic model there are potentially a wide range of applications. LÄS MER

  7. 5. Silicon Carbide Reinforced Alumina and Mullite Ceramics

    Författare :Stefan Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ceramic Nanocomposites; Creep; SEM; SiC; Grain Boundaries; Microanalysis; Mullite; Pressureless Sintering; TEM; Alumina;

    Sammanfattning : The aim of this work was to develop homogeneous ceramic nanocomposite materials with good thermal and structural stability as well as good mechanical properties. The development of microstructure was related to the material properties. LÄS MER
