Sammanfattning : This thesis concerns thermal shock damage of ceramicmaterials. More specifically the work is focused on theoreticaland practical aspects of a new technique for determining thethermal shock resistance of brittle materials. LÄS MER
2. Exosomes and the NKG2D receptor-ligand system in pregnancy and cancer : using stress for survival
Sammanfattning : Although not obvious at first sight, several parallels can be drawn between pregnancy andcancer. Many proliferative, invasive and immune tolerance mechanisms that supportnormal pregnancy are also exploited by malignancies to establish a nutrient supply andevade or edit the immune response of the host.

3. From behaviour to genes: anti-predator responses of brown trout (Salmo trutta) under winter conditions
Sammanfattning : Temperature has major effects on the performance of poikilotherms. In encounters with predators, low winter temperatures constrain predator detection and escape capabilities in prey fishes. LÄS MER
4. Cold exposure and thermal comfort among patients in prehospital emergency care : innovation research in nursing
Sammanfattning : BackgroundPatients’ cold exposure is a neglected problem in prehospital emergency care. Cold stress increases pain and anxiety and contributes to fear and an overall sense of dissatisfaction. When left untreated, cold stress disturbs vital body functions until ultimately reaches hypothermia. LÄS MER
5. Modeling and Testing of Insulation Degradation due to Dynamic Thermal Loading of Electrical Machines
Sammanfattning : Electrical machines in electrified vehicles are subjected to dynamic loadings at different driving conditions, which results in dynamic temperatures. The aging of the Electrical Insulation System (EIS) in electrical machines is caused by these dynamic temperatures, namely high average temperatures and temperature cycles. LÄS MER
