  3. 2. Mechanical Properties of Welds at Creep Activation Temperatures

    Författare :Henrik C.M. Andersson-Östling; Rolf Sandström; Kamran Nikbin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; creep; creep crack propagation; OFHC copper; welds; nuclear waste disposal; creep modeling; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Welds in materials intended for service at temperatures above the creep activation temperature often develop damage before the base metal. The weld is a discontinuity in the material and stresses and strains often accumulate in the weld. Knowledge of the properties of the weld is essential to the safe operation of the component containing the weld. LÄS MER

  4. 3. Investigation of Mechanics of Mutation and Selection by Comparative Sequencing

    Författare :Michael C. Zody; Kerstin Lindblad-Toh; Leif Andersson; Chad Nusbaum; Henrik Kaessmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chicken; chimpanzee; human; evolution; segmental duplication; structural variation; chromosomal rearrangement; comparative genomics; positive selection; selective sweep; Genetics; Genetik; Genetics; genetik;

    Sammanfattning : The process of evolution is of both scientific and medical interest. This thesis presents several studies using complete genomic reference sequences, comparative genomic data, and intraspecific diversity data to study the two key processes of evolution: mutation and selection.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Emergency healthcare; Everyday work; Competencies; Emergency Department; Practitioners; Management; Content analysis; Integrated nursing science;

    Sammanfattning : The overall aim of this thesis is to obtain an understanding of Emergency Healthcare Work (EHW) at the Emergency Department (ED), including the competencies required by EHW, and based on practitioners' and managers' perspectives. Methods: In study I, a quantitative method was employed. LÄS MER

  7. 5. Fatigue behaviour of a nickel based superalloy

    Författare :Henrik Andersson; Materialteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; Bodner-Partom; Fatigue; High temperature;

    Sammanfattning : This thesis deals with different aspects of fatigue crack propagation in IN718. The ultimate objective of the work is to gain understanding of the fatigue process, from the macroscopic stress-strain relations to microscopic fatigue crack growth mechanisms. LÄS MER
