16. Biological optimization of angle of incidence and intensity modulation in breast and cervix cancer radiation therapy
Sammanfattning : Biological treatment optimization aim at improving radiation therapy by accounting for the radiobiological tumour and normal tissues response properties when optimizing the dose delivery. Generally traditional methods, using only dosimetrical measures, disregard the nonlinear radiation response of different tumours and normal tissues. LÄS MER
17. Exploring Knowledge Intensity in Entrepreneurship: A Quantitative Study of Knowledge, Innovation and Performance in Entrepreneurial Firms
Sammanfattning : This Ph.D. dissertation investigates the statistical and theoretical relationships between different dimensions of knowledge intensive entrepreneurship (KIE) in Europe and how knowledge intensity and performance in entrepreneurial firms can be related. LÄS MER
18. Effects of high intensity focused ultrasound on the intervertebral disc
Sammanfattning : The purpose of this study was to study and try to optimise high intensity focused ultrasound treatment of the intervertebral disc. We demonstrated that it was possible to heat intervertebral discs with HIFU delivered by 50 or 5 mm diameter ultrasound transducers. LÄS MER
19. Bio-psychosocial analyses of acute and chronic pain, especially in the spine - the effect of distress on pain intensity and disability
Sammanfattning : The overall purpose was to assess factors that influence the experience of pain and disability due to acute low back pain (LBP) and chronic musculoskeletal pain (CMP). A further purpose was to outline the conceptual framework behind pain—with emphasis on the spine—and its management in primary healthcare. LÄS MER
20. 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
