1. Atmospheric Corrosion of Lead. The Influence of Organic acid Vapours and Inorganic Air Pollutants. A contribution Towards Understanding the Environmental Degradation of Historic Organ Pipes
Sammanfattning : This thesis presents different perspectives on the atmospheric corrosion of lead, aiming at a better understanding of the environmental degradation of historical organ pipes. Corroded organ pipes from the field have been analyzed and the environment inside the organ wind system has been mapped. LÄS MER
2. Atmospheric Corrosion of Historic Lead Organ Pipes
Sammanfattning : The atmospheric corrosion of lead is investigated, with the aim to improve the understanding of the environmental degradation of historical organ pipes. Fieldwork is combined with laboratory investigations. The field studies included characterization of the organ environment and exposures of lead coupons. LÄS MER
3. Immunological effects of interferon-beta and glatiramer acetate in multiple sclerosis
Sammanfattning : Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system, which results in demyelination, axonal loss and neurological deficits. The aetiology is unknown, however, immunopathological events, which are believed to be of an autoimmune nature, are considered to be responsible for the development of the disease. LÄS MER
4. Studies of Dielectric Relaxation in Solid Polymers and Composites
Sammanfattning : Non-linear characteristics of homogeneous solid polymers and solid polymer-based composites have been studied both experimentally and theoretically. In particular experimental studies of non-linear dielectric response of six homogeneous solid polymeric materials and the influence of the composition on the properties of solid polymer-based composites with high dielectric permittivities have been carried out and a theoretical study of dipole-dipole interaction in solids based on a formulation due to P.

5. Microbial Phosphorus Removal in Waste Stabilisation Pond Wastewater Treatment Systems
Sammanfattning : Waste Stabilisation Ponds (WSPs) are characterised by low phosphorus (P) removal capacity. Heterotrophic bacteria are principal microbial agents in WSPs in addition to algae. LÄS MER
