  1. 1. Pressure sores : risk assessment and prevention

    Författare :Margareta Lindgren; Christina Lindholm; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The aims of this thesis were to study the prevalence, incidence, prevention and treatment of pressure sores, to further develop a risk assessment scale, and test the reliability and validity of this scale, to identify risk factors for pressure sore development, and to study skin blood flow in non-blanchable erythema areas as compared to undamaged skin.Criteria used for pressure sore assessment were persistent discoloration i.

  3. 2. Prediction of Cooling Air Flow in Electric Generators

    Författare :Pirooz Moradnia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Multiple Reference Frame; PIV; Total Pressure Measurements; Electric Generator; Experimental Measurements; 5-hole Pressure Probe Measurements; Flow Prediction; OpenFOAM;

    Sammanfattning : The cooling air flow in hydro power electric generators is investigated experimentally and numerically. A fully predictive numerical approach is presented and validated, in which the inlet and outlet boundaries are eliminated from the computational domain. LÄS MER

  4. 3. A systems approach to ice loads on concrete dams

    Författare :Rikard Hellgren; Richard Malm; Anders Ansell; Erik Nordström; Pierre Legér; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ice loads; Ice pressure; Dam safety; Concrete dams; Cold regions; Monitoring; Measurements; Concrete Structures; Betongbyggnad;

    Sammanfattning : Dams are mainly used for the storage of water to electricity production and irrigation, or for river regulation. Continuous work to assure a high dam safety level is a prerequisite to minimize the risk for the uncontrolled release of water. LÄS MER

  5. 4. Greater trochanteric pain after total hip arthroplasty : incidence, clinical outcome, associated factors, tenderness evaluation with algometer and a new surgical treatment

    Författare :Arkan Sam Sayed-Noor; Lars Weidenhielm; Umeå universitet; []
    Nyckelord :greater trochanteric pain; total hip arthroplasty; leg length discrepancy; algometer; pressure-pain threshold; ilio-tibial band; lengthening; Orthopaedics; ortopedi;

    Sammanfattning : Greater trochanteric pain (GTP) is a regional pain syndrome characterized by lateral hip pain and tenderness. Its incidence after total hip arthroplasty (THA) is variable. LÄS MER

  7. 5. Proteomic, metabolomic, and microbiome studies of blood pressure

    Författare :Yi-Ting Lin; Johan Sundström; Martin Magnusson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; hypertension; proteomics; metabolomics; microbiome; molecular epidemiology; Mendelian randomization;

    Sammanfattning : Hypertension is a major risk factor for cardiovascular disease and premature death with a substantial global economic burden. To prevent and treat hypertension, it is crucial to improve our understanding of the pathophysiological mechanisms. Hypertension is a multifactorial condition influenced both by genetic and environmental factors. LÄS MER
