11. Radiotherapy Gel Dosimetry: Development and Application of Normoxic Polymer Gels
Sammanfattning : In many radiotherapy applications, true three-dimensional dosimetry with good spatial resolution that can be achieved in a single measurement would be of great value. Polymer gel dosimetry fulfils many of the demands on such a system. In this study, methods to facilitate the implementation of gel dosimetry have been investigated. LÄS MER
12. A probabilistic approach to risk analysis : a comparison between undesirable indoor events and human sensitivity
Sammanfattning : The main objective of this thesis is to develop a probabilistic procedure similar to the one used in modern design codes for building structures. The purpose of the procedure is to estimate the risk of an unhealthy indoor environment to occur, i.e. LÄS MER
13. Nonmalignant health effects of arsenic exposure
Sammanfattning : This thesis comprises a series of studies concerning occupational and environmental exposure to arsenic and some novel chronic health effects of this element, namely diabetes mellitus and hypertension. Substantial prevalence of the well-known skin manifestations of arsenic ingestion was also found to occur as a result of environmental exposure through drinking water. LÄS MER
14. Inhibition of 11 ß-HSD. Hemodynamic and hormonal response induced by liquorice
Sammanfattning : Introduction: The enzyme 11 ß-hydroxysteroid-dehydrogenas (11 ß-HSD) type 2 that converts the active hormone cortisol to the inactive cortisone is inhibited by glycyrrhetinic acid (GA), the active substance in liquorice. This leads to hypertension, hypokalaemia and sodium- and fluid retention, the syndrome of pseudo-hyperaldosteronism. LÄS MER
15. Indoor Environmental Factors and its Associations with Asthma and Allergy Among Swedish Pre-School Children
Sammanfattning : It has been shown in a large number of scientific studies that living or working in a building with mould and moisture damage increases the risk for asthmatic and allergic symptoms. However, there is a need to establish more valid methods to obtain a more nuanced picture of the wide range of different types of moisture related problems. LÄS MER
