  1. 21. Service Life Estimations in the Design of Buildings : A Development of the Factor Method

    Författare :Björn Marteinsson; Högskolan i Gävle; []
    Nyckelord :Construction engineering; factor method; service life prediction; durability; degradation;

    Sammanfattning :   The built environment usually constitutes a very important part of the real capital of a nation, and the construction sector represents more than 10% of the yearly Gross National Product of the industrialised world. Good planning of all construction is important, and consideration of the service life of the work is of great interest and is a significant aspect of sustainability considerations. LÄS MER

  3. 22. On the Design and Life Prediction of Transmission Belts Made of Elastomer Composites

    Författare :Dag Fritzson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; Material properties; Elastomer; Composite; Damage; Fatigue; Viscoelastic; Anisotropic; Wear; Constitutive theory; Life prediciton; V-belt; Belt transmission; Rubber;

    Sammanfattning : Next to gear transmissions, belt transmissions are the most important mechanical transmissions. Today, belt design and development is based on extensive application tests of belts in the product development process. There is a need for theory development and design support systems. LÄS MER

  4. 23. Improving a bridge fatigue life prediction by monitoring

    Författare :John Leander; Raid Karoumi; Mohammad Al-Emrani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : For steel railway bridges, fatigue is the main reason for a limited service life. An initial prediction of the fatigue life is usually performed using loads and conservative assumptions stated in the governing standards. The result is used for decisions of further actions.

  5. 24. Obesity in obstetric care : Consequences and risk prediction

    Författare :Heiðrún Pétursdóttir Maack; Inger Sundström Poromaa; Þóra Steingrímsdóttir; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : The incidence of obesity is increasing at an alarming rate worldwide and the epidemic has reached the pregnant population of developed countries. Obesity is associated with several obstetric complications for both the mother, the fetus and the new-born. Today, obesity risk assessment is based on body mass index (BMI). LÄS MER

  7. 25. The Design and Structure Prediction of Protein Oligomers

    Författare :Robert Lizatovic; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virus capsids; coiled coils; molecular replacement; symmetry; Rosetta; protein design; structure prediction;

    Sammanfattning : The minimum free energy state of a protein (the native state) is encoded by its amino-acid sequence. Due to the many torsional degrees of freedom (DOF) available to a polypeptide chain, a vast number of conformations is possible. LÄS MER
