11. Evaluating Resistance to Corona and Ozone in Polymeric Materials for High Voltage Outdoor Applications
Sammanfattning : Resistance to corona discharges and ozone, the well known ageing factors for polymeric materials used in outdoor insulation, has been listed as being of great importance among twelve properties identified by CIGRE WG D1.14 – Material Properties for Non-ceramic Outdoor Insulation.

12. Spatially resolved gas sensing
Sammanfattning : By using a Scanning Light Pulse Technique (SLPT) the gas response of catalytic Metal-Insulator semiconductor (MIS) devices can be spatially resolved.The application of SLPT to gas sensitive MIS devices can be divided into two areas. LÄS MER
13. The Palaeopathology of Kirchberg : Evidence of Deficiency, Inflammatory and Tumorous Disease in a Medieval Rural Population in Hessia, Germany
Sammanfattning : This study investigates the interaction of disease processes, disease and environment, female and male health as well as health and ageing in a medieval rural village population. For this purpose multiple skeletal indicators of health have been studied, including deficiency, inflammatory, infectious and tumorous disease. LÄS MER
14. Partial Discharges Studied with Variable Frequency of the Applied Voltage
Sammanfattning : This thesis concerns partial discharge (PD) diagnostics withvariable frequency of applied voltage in the frequency range 1mHz - 400 Hz. The exploration of a new type of spectroscopythat combines partial discharge analysis and dielectricresponse is demonstrated. LÄS MER
15. Epithelial stem cells in Hutchinson-Gilford progeria syndrome
Sammanfattning : Hutchinson-Gilford progeria syndrome (HGPS) and restrictive dermopathy (RD) are two rare genetic disorders that affect children. Complications from cardiovascular disease, including atherosclerosis, are the most common cause of death in HGPS, which occurs at around 13 years of age. LÄS MER
