  3. 22. Assessment of skeletal structure by MR relaxometry

    Författare :Torkel B Brismar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :magnetic resonance imaging; bone and bones; osteoporosis;

    Sammanfattning : Introduction: More than 40 per cent of all women older than 50 years will suffer from a hip, wrist or vertebral fracture. Most of these fractures are related to bone fragility, osteoporosis. If the disease is diagnosed and treated at an early stage the risk of fracture can be decreased. LÄS MER

    Sammanfattning : The general objective of this thesis was to describe a system for fundus photography for early diagnosis of diabetic retinopathy, performed by mobile teams visiting primary health care centres in Stockholm County. Large-scale implementation showed this method to be feasible, acceptable, and popular. LÄS MER

  5. 24. Atomic Scale Modelling in Photoelectrocatalysis : Towards the Development of Efficient Materials for Solar Fuel Production

    Författare :Giane B. Damas; Carlos Moyses Araujo; Rajeev Ahuja; Clas Persson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photocatalytic hydrogen production; polymeric materials; donor-acceptor architecture; small molecules; density functional theory; hydrogen binding free energies; exciton binding energies; electrocatalysis; carbon dioxide conversion; formic acid production; Sn-based electrodes; Tin oxides; Ru-complexes; Metal Organic Frameworks; carbon dioxide capture.;

    Sammanfattning : Using sunlight to produce valuable chemicals has been pointed out as an interesting alternative to deal with the well-known environmental problem related to the use of fossil fuels for energy generation. Thus, it is crucial for this field the development of novel photocatalysts that could drive the uphill reactions with high efficiency while presenting low price and toxicity. LÄS MER

  7. 25. Cardioplegia and cardiac function : evaluated by left ventricular pressure-volume relations

    Författare :Anders B Ericsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cardioplegia; simultaneous cardioplegia; intermittent warn cardioplegia; cardiac function; pressure-volume loops; conductance catheter; heart rate;

    Sammanfattning : Purpose: This thesis is focused on studies of blood cardioplegia in order to evaluate regimens of myocardial protection during cardiac surgery. To further bring down operative mortality and morbidity, in patients with acutely ischaemic hearts, an optimal peroperative myocardial management is essential. LÄS MER
