  1. 1. On the role of dendritic cells in HIV-1 infection

    Författare :Anna Smed Sörensen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dendritic cell; plasmacytoid; myeloid; HIV-1; cytokines; co-stimulation; transmission; antigen presentation; apoptotic cells; MuLV;

    Sammanfattning : Dendritic cells (DCs) are antigen-presenting cells with the capacity to initiate primary T cell responses against pathogens such as HIV-1. In addition, DCs express the receptors required for HIV-1 infection and as DCs are prevalent in the mucosa, they encounter the virus early after sexual transmission. LÄS MER

  3. 2. Novel Diagnostics and Computational Methods of Neutron Fluxes in Boiling Water Reactors

    Författare :John Loberg; Michael Österlund; Thomas Smed; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Void; BWR; neutron fluxes; channel bow; MCNP; 2D 3D; Physics; Fysik;

    Sammanfattning : The focus in this thesis is to improve knowledge of the BWR related uncertainties void, channel bow, and control rods. The presence of void determines the moderation of neutrons in BWRs. A high void fraction is less efficient in moderating neutrons than a low one. LÄS MER

  4. 3. Sin egen hälsas smed : Idéer, initiativ och organisationer inom svensk motionsidrott 1945–1981

    Författare :Hans Bolling; Bill Sund; Jan Lindroth; Susanna Hedenborg; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; sport history; sports for all; sports movement; health; fitness; physical activity; welfare state; History; Historia;

    Sammanfattning : This dissertation studies the spread of sports for all in Sweden during the years 1945 to 1981. The purposes of the dissertation are twofold: in part to survey the forms of physical activities which were launched as sports for all after 1945, in part to answer the question: Why have almost all voluntarily organized sports in Sweden been part of one organization since the 1970s? In order to handle the diversities of activities that can fall within the concept of sport, two principal abstractions of the concept are used: one rigorous and one flexible. LÄS MER

  5. 4. Evaluation of Resetting Performance in Cellular Manufacturing Systems - A Structured Approach to Sustainable Improvement of Resetting Performance

    Författare :Jürgen E. Kaiser; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resetting reduction set-up ; SMED; manufacturing responsiveness;

    Sammanfattning : This thesis deals with the question of how to achieve responsiveness in cellular manufacturing systems, with special emphasis given to the rapid resetting between product runs. Findings from action research in cellular manufacturing systems are presented, along with a comprehensive methodology for resetting improvements based on performance evaluation. LÄS MER

  7. 5. Disruption Analysis - An Important Tool in Lean Production

    Författare :Johan Ericsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production technology; TPM.; Kaizen; JIT; Lean Production; Manufacturing system; Disruption; Downtime; Produktionsteknik;

    Sammanfattning : This thesis is divided in two parts which are strongly connected. Part one deal with disruptions occurring in connection with machine down-time, quality losses and increased cycle time. The analysis is based on 10 studies, in which down-time losses in Swedish industry have been registered. LÄS MER
