    Sammanfattning : Endemic thyroid disorders (ETD) are major health problems worldwide. Although the major role of iodine deficiency in the etiology of ETD is well founded, other factors have been shown to contribute to its etiology as well. LÄS MER

  3. 2. Inhomogenity in microstructures

    Författare :Jacek Komeda; KTH; []
    Nyckelord :;

    Sammanfattning : The purpose of the present thesis is to quantitativelycharacterise structural features which contribute to thematerial anisotropy and to relate developed parameters to thematerial properties. Various forms of structural inhomogeneitywere quantified with the help of comuterised image analysisusing quantitative metallography and statistical analysismethods. LÄS MER

  4. 3. A study on contact fatigue mechanisms

    Författare :Bo Alfredsson; KTH; []
    Nyckelord :contact fatigue mechanism; spall; spalling; surface crakc; sub-surface crack; elesto-plastic indentation; contact compliance measurement; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Surfaces subjected to rolling and sliding contacts maysuffer from contact fatigue. This thesisdeals with solidmechanic aspects of contact fatigue including the descriptionand verificationof explaining mechanisms. The new mechanism forsurface initiated contact fatigue is basedon tensile surfacestresses from local asperity contacts. LÄS MER

  5. 4. Genetic design for facilitated production of human peptide hormones inEscherichia coli

    Författare :Per Jonasson; KTH; []
    Nyckelord :;

    Sammanfattning : Genetic strategies have become important in the design ofefficient processes for production of recombinant proteins.When constructing a production scheme, inherent properties,purity and quality requirements, as well as the final use ofthe protein, have to be considered. LÄS MER
