  1. 1. Physical activity, cardiorespiratory fitness, and abdominal obesity in relation to cardiovascular disease risk : epidemiological studies

    Författare :Elin Ekblom Bak; Mai-Lis Hellénius; Björn Ekblom; David Dunstan; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : Although Sweden saw a decline in death rates related to cardiovascular disease (CVD) between 1987 and 2011, it is still the most common cause of death for both women and men. Lifestyle-related factors such as inadequate physical activity (PA), poor cardiorespiratory fitness (CF), and excess body fat are all recognised as important predictors of CVD morbidity and mortality.

  3. 2. Physical properties and structural stability of carbon nanotubes under extreme conditions

    Författare :Maxime Noël; David Dunstan; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. LÄS MER

  4. 3. Aquaporin homologues in Norway spruce (Picea abies)

    Författare :Peter Oliviusson; David I. Dunstan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Sammanfattning : The recent discovery of aquaporins - proteins that mediate bidirectional passage of water over membranes - provides a molecular basis for the underlying processes in plant water relations. In plants, aquaporins are found in plasma membranes and in vacuolar membranes (tonoplasts) and are suggested to participate in dynamic operations such as cell elongation, osmotic regulation, and long-distance transport.
