  1. 11. Mechanical Behaviour of Single-Layer Adhesive Joints : an integrated approach

    Författare :Li Högberg; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; beam adhesive layer model; energy release rate; fracture; integrated; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Sammanfattning : Innovative products that are competitive on the market are likely to employ newtypes of materials and unusual geometries. A method that can assemble dissimilarmaterials and irregular geometries cost-effectively and at the same time offera joint that is light in weight and imperceptible, is optimal. LÄS MER

  3. 12. Significance of Wilms’ tumor gene 1 as a biomarker in acute leukemia and solid tumors

    Författare :Charlotta Andersson; Eva Lundin; Aihong Li; Andreas Jonsson; Xingru Li; David M. Loeb; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wilms’ tumor gene 1; biomarker; leukemia; renal cell carcinoma; ovarian carcinoma; Clinical Chemistry; klinisk kemi; patologi; Pathology;

    Sammanfattning : Wilms’ tumor gene 1 (WT1) is a zinc finger transcriptional regulator with crucial functions in embryonic development. Originally WT1 was described as a tumor suppressor gene, but later studies have shown oncogenic properties of WT1 in a variety of tumors. Because of its dual functions in tumorigenesis, WT1 has been described as a chameleon gene. LÄS MER

  4. 13. Towards an accurate determination of lignin in chemical pulps : The meaning of kappa number as a tool for analysis of oxidable groups

    Författare :Jiebing Li; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Lignin content is the most important parameter in chemicalpulping. At present, kappa number is the most common parameterfor determination of lignin content and the base for otheron-line methods and for industrial automation (Chapter 1). LÄS MER

  5. 14. Classical Wigner Method with an Effective Quantum Force

    Författare :Huaqing Li; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this work, I will present an effective way to study the dynamics in phase space and obtain the rate constants. Our method is based on the Classical Wigner (CW) model, which is an approximate method for including quantum mechanical effects into molecular simulations. LÄS MER

  7. 15. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects

    Författare :Peigang Li; Lars-Erik Svensson; Norbert Enzinger; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tandem GMAW; old laps; lack of fusion; Spatter; Overlap; Overflow; Manganese; Silicon; Oxides; Temperature; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).
