  1. 1. Borehole heat store design optimization

    Författare :Bo Nordell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Seasonal heat storage, which is used to balance the supply of and demand for heat, e.g. in district heating networks, is necessary for the large-scale utilization of solar heat. The aim of this thesis was to study and develop seasonal heat storage to a point where it, if possible, would be an option in Swedish heating systems. LÄS MER

  3. 3. Falls, fractures and function. Focus on women with a distal forearm fracture

    Författare :Eva Nordell; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical medicine; elderly; falls; Distal forearm fracture; fractures; health-related quality of life; risk factors; physical performance; rehabilitation; Rehabilitering medicinsk och social ; kinesitherapy; revalidation;

    Sammanfattning : Falls and fractures in older people are a common and increasing health problem which causes physical, social and psychological problems for the individual and is costly to society. The aims of this thesis were to investigate accidental falls of patients aged 65 - 74 who attended an orthopedic emergency ward, to investigate reliability of the modified figure of eight (MFE) and compare it with other balance performance tests, to investigate whether patients with a distal forearm fracture exhibited risk factors for new falls and fractures, and to follow physical performance and evaluate health-related quality of life in women after a distal forearm fracture.
