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

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

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

Recurrent disease after operation for colorectal carcinoma is a major problem for patients and for their doctors. Scientific evidence for guidelines is poor. It appears that intensive surveillance increases survival but we do not know which parameters in surveillance are important for this result.

This paper presents a new analytical solution for the influence of regional groundwater flow on the performance of borehole heat exchangers. The solution concerns a vertical borehole. The transient thermal response for the fundamental case of a step-change in heat injection rate is given. The solution is remarkably simple and the formulas quite handy considering the complexity of the convective-di

Popular Abstract in Swedish Värdebaserad styrning har på senare tid tilldragit sig mycket intresse från såväl akademiker som praktiker. På basis av fallstudiemetod beskrivs, analyseras och konceptualiseras värde¬bas¬erad styrning utifrån ett ekonomistyrningsperspektiv. Medan tidigare forskning har fokuserat på de presstationsmått som lanseras i den normativa litteraturen visar denna avhandling atValue-based management has attracted considerable interest among organizations and academics in recent years. Responding to calls for case-based research, this thesis describes, analyses and conceptualizes value-based management as a management accounting construct. While previous research has focused on the measures (eg. EVA) advanced in the normative literature, this analysis demonstrates that
