1. Borehole heat store design optimization
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. Falls, fractures and function. Focus on women with a distal forearm fracture
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.

4. Metall organic vapour phase epitaxy for advanced III-V devices
Sammanfattning : Metalorganic vapour phase epitaxy (MOVPE) has proven to be a successful method for growth of structures for advanced optoelectronic semiconductor devices in III-V compounds. This thesis deals with technological and process related aspects of MOVPE from an experimental perspective. LÄS MER
5. Aluminium oxide - poly(ethylene-co-butylacrylate) nanocomposites : synthesis, structure, transport properties and long-term performance
Sammanfattning : Polymer nanocomposites are promising materials for dielectrical use in high voltage applications and insulations. This work presents a study of nanocomposites based on poly(ethylene-co-butyl acrylate) with two different comonomer compositions and two different aluminium oxide nanoparticles. LÄS MER
