  1. 1. QTL Analysis in the Pig : From the Identification of Quantitative Trait Loci to the Understanding of Molecular Mechanisms

    Författare :Ellen Markljung; Leif Andersson; Göran Andersson; Göran Hjälm; Stefan Marklund; Holger Luthman; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Domestic pigs have become very different form the wild ancestors they originate from. Selection for muscle growth and meat quality has made the pig a good model for genetic studies of muscle development.The first part of this thesis presents a genome-wide scan for quantitative trait loci (QTL) in a cross between Landrace and Hampshire pigs.

  3. 2. Finite element simulation of airbag deployment and optimization in crashworthiness design

    Författare :Per-Olof Marklund; Göran Sandberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The passive safety of cars is of uttermost importance for the automotive industry. To improve the safety of cars, computer simulations of the vehicle and occupant system by the Finite Element Method (FEM), have become an industry standard tool. LÄS MER

  4. 3. Cluster investigations of the extent and altitude distribution of the auroral density cavity

    Författare :Love Alm; Göran T. Marklund; Tomas Karlsson; Rickard Lundin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Auroral density cavity; auroral accelaration; Cluster; in situ observation; electron density; pseudo altitude; Physics; Fysik;

    Sammanfattning : The auroral density cavity constitutes the boundary between the cold, dense ionospheric plasma and the hot, tenuous plasma sheet plasma. The auroral density cavity is characterized by low electron density and particle populations modified by parallel electric fields. LÄS MER

  5. 4. Fine-scale morphology and spectral characteristics of active aurora

    Författare :Hanna Dahlgren; Göran Marklund; Nickolay Ivchenko; Kari Kaila; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aurora; Space physics; Rymdfysik;

    Sammanfattning : Ground-based and in-situ observations of the aurora demonstrate an extreme richness in fine structure, with spatial scales down to tens of metres and time variations occurring on a fraction of a second. To further our understanding of the aurora, it is esssential to understand the mechanisms responsible for the small-scale structuring, since this is an intrinsic property of the auroral plasma.

  7. 5. Multi-spectral analysis of fine scale aurora

    Författare :Hanna Dahlgren; Göran Marklund; Nickolay Ivchenko; Fred Sigernes; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasma physics; Plasmafysik; Optics; Optik;

    Sammanfattning : The Aurora Borealis is the visible manifestation of the complex plasma interaction between the solar wind and the Earth's magnetosphere and ionosphere. Ground based and in situ measurements demonstrate a prevalence of dynamic fine structure within auroral displays, with spatial scales down to tens of metres and time variations occurring on a fraction of a second.
