21. Human response to wind turbine noise : perception, annoyance and moderating factors
Sammanfattning : Aims: The aims of this thesis were to describe and gain an understanding of how people who live in the vicinity of wind turbines are affected by wind turbine noise, and how individual, situational and visual factors, as well as sound properties, moderate the response.Methods: A cross-sectional study was carried out in a flat, mainly rural area in Sweden, with the objective to estimate the prevalence of noise annoyance and to examine the dose-response relationship between A-weighted sound pressure levels (SPLs) and perception of and annoyance with wind turbine noise.

22. Physical activity and health benefits
Sammanfattning : Physical activity (PA), due to its role in health promotion and disease prevention, is of particular interest to be investigated. The aims of this thesis were: to assess the associations between PA and different health outcomes (lower urinary tract symptoms, cancer incidence, and mortality) in the Cohort of Swedish Men (COSM); to perform a dose-response meta- analysis of published associations between walking and incidence of coronary heart disease (CHD); and to provide user-friendly software packages for dose-response meta-analysis and for sensitivity analysis of biases in observational studies.

23. Early life factors and the long-term development of asthma
Sammanfattning : Asthma, a huge burden on millions of individuals worldwide, is one of the most important public health issues in many countries. As genetic and environmental factors interact, asthma may be programmed very early in life, perhaps even in utero. LÄS MER
24. Skin phototesting using a divergent ultraviolet B beam : development and evaluation on a normal material
Sammanfattning : The phototesting method proposed provokes the skin by means of a divergent UVB beam. The beam divergence is induced by an optical plano-concave !ens placed at the opening of the light guide which directs the light from the UV lamp to the skin. LÄS MER
25. Smoking and cancer among Swedish women
Sammanfattning : Cancer has been the second most frequent cause of death in Sweden and in other developed countries for most of the 20th century, and today accounts for about 25 per cent of all mortality. While the trend in overall cancer mortality has been increasing among men, the picture is less clear regarding women. LÄS MER
