  1. 21. Experiments on sheet metal shearing

    Författare :Emil Gustafsson; Magnus Eriksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; Simulering av klippning i höghållfast stål;

    Sammanfattning : Within the sheet metal industry, different shear cutting technologies are commonly used in several processing steps, e.g. in cut to length lines, slitting lines, end cropping etc. LÄS MER

  3. 22. The telomere binding proteins in yeast and their role in telomere maintenance

    Författare :Cecilia Gustafsson; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Telomeres are the end-structures of linear chromosome which are crucial for maintaining genome integrity. The telomeres prevent the DNA-repair machinery from recognizing the chromosome ends as double-strand breaks and from end-to-end fusions. LÄS MER

  4. 23. The insulin-like growth factor system : effects of circulating proteases

    Författare :Sara Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The insulin-like growth factor-I and -II (IGF-I/-II) are peptide hormones important for growth and metabolism. They stimulate cell proliferation and differentiation and inhibit apoptosis. In addition, they have insulin-like effects on glucose and amino acid metabolism. LÄS MER

  5. 24. Exercise and angiogenic growth factors in human skeletal muscle

    Författare :Thomas Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adapatation; angiogenesis; angiogenic growth factors; blood flow; gene expression; gene regulation; human; ischaemia; skeletal muscle; training;

    Sammanfattning : Long-term electrical stimulation and endurance exercise increase the amount of capillaries in skeletal muscle. VEGF-A is a well-characterized stimulatory angiogenic growth factor and has shown to play an important role in angiogenesis in pathological conditions in humans and in physiological conditions in animal models.

  7. 25. Population genetic analyses in the orchid genus Gymnadenia : a conservation genetic perspective

    Författare :Susanne Gustafsson; Pia Mutikainen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Genetic engineering; Orchidaceae; Gymnadenia; conservation; microsatellites; genetic structure; mating pattern; Genteknik; Genetic engineering including functional genomics; Genteknik inkl. funktionsgenomik; naturvårdsbiologi; Conservation Biology;

    Sammanfattning : Small populations are facing a particular risk of extinction due to a lack of appropriate genetic diversity and associated negative effects, factors dealt with in the discipline of conservation genetics. Many orchid species exhibit characteristics that make them a perfect study object in the scope of conservation genetics. LÄS MER
