21. Ageing of Asphalt Mixtures : Micro-scale and mixture morphology investigation
Sammanfattning : There are many variables that affect the viscoelastic properties of asphalt mixtures with time, among which age hardening may be considered one of the important ones. Age hardening of asphalt mixtures is an irreversible process, which contributes to a reduction of the durability of pavements and eventually increases the maintenance cost. LÄS MER
22. Oxygen Induced High Temperature Crack Growth in Ni-base Superalloys
Sammanfattning : Oxygen induced crack growth is a serious concern for the performance of Ni-base superalloys. These alloys are used in gas-turbine engines where they are exposed to hightemperatures, mechanical loads and oxygen-rich environments. LÄS MER
23. Biophysical aspects of the skin barrier : towards increased non-invasive extraction and optimized biomarker sampling
Sammanfattning : The skin provides a link to the body’s health via its rich variety of high and low molecular weight biomarkers, reflecting both systemic diseases (e.g., cancer, diabetes) and local skin disorders (e.g. LÄS MER
24. Computational framework for studying charge transport in high-voltage gas-insulated systems
Sammanfattning : Electrical switchgear industry dealing with transmission and distribution of power is strongly affected by the changing dynamics of climate control. Their main contribution to the global warming is through SF6 gas, having a GWP of 23500 (times of CO2). SF6 plays an important role in providing electrical insulation for these high voltage systems.

25. The skin barrier : structure and physical function
Sammanfattning : The objective of the project "The skin barrier - structure and physical function" was to characterise in detail the human skin barrier structurally and functionally. The thesis work includes in-vivo studies, in-vitro studies and studies on pure model systems. LÄS MER
