  1. 1. Computational methods for on-line shape inspection

    Författare :Per Bergström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Scientific Computing; Teknisk-vetenskapliga beräkningar;

    Sammanfattning : This licentiate thesis describes computational methods that solve problems occurring in industrial on-line shape quality inspection of produced items. These items are measured and compared with their corresponding CAD object. The meaning of on-line is that the inspection is done on-line in the production line, i.e. LÄS MER

  3. 2. Growth factor receptor signalling in thyrocytes of normal and neoplastic origin

    Författare :Daniel Bergström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; thyroid; carcinoma; HGF; Met; TGF-β; EGF; receptor signalling; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Cellular growth and function are controlled by stimulatory and inhibitory factors actingthrough specific receptors. The present thesis focuses on the role of growth factors, theirreceptors and signalling pathways in normal and neoplastic thyroid epithelial cell biology. LÄS MER

  4. 3. Three Realities : Women in different phases of drug abuse - a social psychological investigation

    Författare :Marie Bergström; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gender; Applied and experimental psychology; social psychology; personality; drug addiction; Tillämpad och experimentell psykologi; women; DMTm;

    Sammanfattning : The purpose of this study was to systematically examine the social, cultural and psychological situation of a group of women with drug addiction, and to gain an understanding of it. Different theoretical perspectives were utilized in efforts to understand and explain why some young women start using drugs. LÄS MER

  5. 4. Integrated Micro-Analytical Tools for Life Science

    Författare :Sara Bergström; Karin Markides; Marit Andersson; Marja-Liisa Reikkola; Uppsala universitet; []

    Sammanfattning : Advances in life science require knowledge of active molecules in complex biological systems. These molecules are often only present for a certain time and at limited concentrations. LÄS MER

  7. 5. The evolution of mating rates in Pieris napi

    Författare :Jonas Bergström; Christer Wiklund; Göran Arnqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : In the green-veined white butterfly (Pieris napi), females obtain direct fitness benefits from mating multiply and studies have shown that fitness increases seemingly monotonically with number of matings. The reason is that at mating males transfer a large nutritious gift (a so called nuptial gift) to the females that the females use to increase both their fecundity and lifespan. LÄS MER
