1. Landskapsarkitektur i järnvägslandskap : platsernas förändring i historiskt perspektiv
Sammanfattning : Järnvägens organisation för skötsel av den yttre miljön avvecklades redan i början av 1970-talet. Järnvägsparker och andra planteringar togs bort eller förenklades för att minska skötselbehovet. Banverket bildades1988 med uppgift att förvalta och utveckla statens spåranläggningar. LÄS MER
2. Studies on Polarised Light Spectroscopy
Sammanfattning : This thesis project focuses on measurements of dermal microcirculation during vascular provocations with polarised light spectroscopy. This is done with a non-invasive method commercially available as Tissue viability imaging (TiVi) which measures concentration and oxygenation of red blood cells in the papillary dermis. LÄS MER
3. Energy based surgical instruments : With particular focus on collateral thermal injury
Sammanfattning : Iatrogenic post-operative nerve dysfunction is a significant problem in many areas of surgery and can be caused by collateral thermal injury from activation of energy based surgical devices (EBD).The aims of this thesis were to: create an animal model in order to compare mono- and bipolar electrosurgery (ES) and an ultrasonic dissection (UD) with regard to collateral thermal nerve injury, and with data of a national multicenter register to study the use of EBD and their potential effects on operation time and complication rates in thyroid surgery.
