Abstract in German Bei der interstitiellen photodynamischen Therapie dicker Hautläsionen hat sich herausgestellt, dass Veränderungen in der Gewebelichttransmission erzeugt werden, was eine unmittelbare Folge der Schwankungen des Gesamtblutvolumens und der Sauerstoffsättigung ist. Zur Simulation der Energiedichte- und der Gesamtlichtdosisverteilung im Zielgewebe wurde in zwei Fällen eine Finite-EleInterstitial photodynamic therapy on thick skin lesions has been shown to induce changes in tissue light transmission as a direct consequence of variations in total blood volume and oxygen saturation. A finite element method was used in order to simulate the fluence rate distribution and total light dose throughout the target tissue for two cases. The first case constitutes a pre-treatment model w

Popular Abstract in Swedish Upprinnelsen till denna avhandling finns i frågan: ”Till vilken nytta skrivs alla akademiska avhandlingar och forskningsrapporter?” Vikten och behovet av att forskningsbasera omvårdnaden har i internationell litteratur belysts i över 40 år. I Sverige började denna process i anslutning till att vårdutbildningarna genom 1977 års högskolereform kom att ingå i universitets-The starting point for this dissertation was the interest in dissemination and utilization of research-based knowledge in practice. The interest in research utilization in USA has spread to nursing from foremost the social sciences. In Sweden there are some studies in research utilization from different fields. The aim of the study was to explore, describe and understand midwives’ approaches to mi

We here show simulation results that by including a small InAsP heterostructure barrier inside the channel of a InAs nanowire transistor it is possible to increase both the sub threshold slope and on-off ratio with only a modest decrease in the drive current for a fixed gate overdrive. The design is based on the fact that the sharp InAsP heterostructure induces a small barrier in the conduction ba

The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curves surfaces and formation of dust have been studied. Typical are stick slip behaviour and threshold stress levels for formation of dust. The emissions of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, mi

Det tänkande som ligger under Kristinas självframställning - livet är ett skådespel - beskrivs, samt de genrebundna mönster för Kristinas jag som hon utnyttjar påvisas i Krisinas text, bl a Plutarkos biografi över Alexander den store, den kvinnliga helgonbiografin. Dessa kan knytas till Kristinas manliga klädsel, hennes transvestism samt till hennes bild av sitt offer(abdikationen)som ett hjältedå

Popular Abstract in English Nowadays, cutting-edge technologies require devices to be small, ultrafast, and operational in a wide range of regimes. To fulfill these requirements we need to go beyond the traditional materials, i.e. to solids with novel, unconventional and tailorable properties. Great progress in this direction is conjectured to stem from materials in which the effect of inter-partiCutting-edge technology needs small, ultrafast devices, operational in a wide range of regimes. This calls for solids with novel, unconventional and tailorable properties. Great progress is expected from materials in which electron-electron and electron-phonon correlations strongly affect the dynamics ( i.e. "unforeseen" useful properties are expected to be most likely found in systems with comple
