    Sammanfattning : The main purpose of this thesis is to analyze the internationalisation of the Grängesberg Company from 1953 to 1980. The strategies that the company used and the knowledge it gained by participating in international mining projects are studied. The first and largest mining activity abroad was the Lamco project in Liberia. LÄS MER

  4. 4. A Search for the Masked Mechanism Behind IgG-Mediated Suppression of Antibody Responses

    Författare :Joakim Bergström; Birgitta Heyman; Jenny Hallgren Martinsson; Frida Henningsson Johnson; Mats Bemark; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FcγR; complement; sheep erythrocytes; IgG-mediated immune suppression; rhesus prophylaxis; rhesus D antigen; germinal center; Immunologi; Immunology;

    Sammanfattning : Antibodies passively administered together with their specific antigen can enhance or suppress the specific antibody response. This phenomenon is known as antibody feedback regulation. Whether this modulation causes up- or downregulation of the antibody response depends both on the antibody isotype and the antigen used.

  5. 5. Influence of microstructure on fatigue and ductility properties of tool steels

    Författare :Mats Randelius; Rolf Sandström; Jens Bergström; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool steels; fatigue; ductility; carbides; carbide cluster; inclusion; size distribution; modelling; FEM; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : Fatigue and ductility properties in various tool steels, produced by powder metallurgy, spray forming or conventionally ingot casting, have been analysed experimentally and successfully compared to developed models. The models are able to predict the fatigue limit and cause for fatigue fracture, and strain- and stress-development until fracture during the ductile fracture process respectively. LÄS MER
