Medical Laser-Induced Thermotherapy - Models and Applications

Heat has long been utilised as a therapeutic tool in medicine. Laser-induced thermotherapy aims at achieving the local destruction of lesions, relying on the conversion of the light absorbed by the tissue into heat. In interstitial laser-induced thermotherapy, light is focused into thin optical fibres, which are placed deep into the tumour mass. The objective of this work was to increase the under

Coming Full Circle? : Return Migration and the Social Mobility on the Bjäre Peninsula 1860-1930

One million three hundred thousand people left Sweden for America between 1860 and 1930. In the same period, approximately two hundred thousand people returned to Sweden. "Coming Full Circle?" is an analysis of the fate and local impact of the local returnees on the Bjäre peninsula in southern Sweden. This thesis examines anew both the sources used by previous Swedish research and previously negle

Bird Vision: Spatial acuity and colour discrimination in bright and dim light

Popular Abstract in Swedish Under dagen, när det är ljust, har fåglar både överlägsen synskärpa och färgseende jämfört med de flesta andra djur, inklusive människan. Men vad händer när det skymmer och under natten när det är mörkt? Vi människor tappar mycket av vår synskärpa i svagt ljus och vi förlorar vårt färgseende när det blir mörkare än ungefär en månupplyst natt. Det här beror på att ljusetBirds use vision to guide navigation, foraging and mate choice, and studies of the limitations in bird visual perception are most helpful for the understanding of bird ecology. Here, I present four studies of bird vision in bright and dim light. Paper I is a quantification of how sensitive colour vision modelling is to variation in data, such as the spectral sensitivity of photoreceptors and recep
