1. Kulturell tid och individuella rytmer : Gymnasieelever om tidens pedagogiska villkor
Sammanfattning : The problem focused in the thesis has its ground in the crossroads between a manifold school-time and shared as well as individual rhythms of pupils. The thesis builds on a theoretical assumption that cultural structures in time are of meaning for an understanding of ourselves and of others, and works as a frame for contemporary values and constraints, especially in school.

2. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams
Sammanfattning : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. LÄS MER
3. Extending MRI to the Quantification of Turbulence Intensity
Sammanfattning : In cardiovascular medicine, the assessment of blood flow is fundamental to the understanding and detection of disease. Many pharmaceutical, interventional, and surgical treatments impact the flow. The primary purpose of the cardiovascular system is to drive, control and maintain blood flow to all parts of the body.

4. Pregnancy and leisure time physical activity
Sammanfattning : ABSTRACT Aims: To examine associations between leisure time physical activity before and during pregnancy and preterm delivery, birth weight, and pre-eclampsia and to describe levels of physical activity prior to and during pregnancy. Furthermore to elucidate women’s experiences and views of leisure time physical activity during pregnancy in a qualitative study. LÄS MER
5. Time-Resolved Spectroscopy and Intensity Measurements of Singly Charged Ions
Sammanfattning : This thesis is mainly concerned with investigations of spontaneous radiatively decaying states in both negative and positive singly charged ions. When possible, the measured lifetime of the state has been combined with branching fractions in order to derive the absolute transition probability (A-value) between different quantum states. LÄS MER
