6. Traumatic Exposure, Bereavement and Recovery among Survivors and Close Relatives after Disasters
Sammanfattning : International studies of disasters indicate the risk for developing posttraumatic stress reactions among survivors is high. Modern life implicates increased traveling. During the last decades a large number of Swedish citizens were confronted with disasters taking place outside of their country. LÄS MER
7. Lärares arbete med individanpassning : Strategier och dilemman i klassrummet
Sammanfattning : A major challenge for teachers in crowded classrooms is to adapt the teaching to different pupil’s needs and abilities. Previous research shows that learning for pupils in the Swedish primary school has somewhat become an individual project. An increase in the individual work has been at the expense of whole class teaching. LÄS MER
8. Nanostructured materials for gas sensing applications
Sammanfattning : In this Thesis I have investigated the use of nanostructured films as sensing and contact layers for field effect gas sensors in order to achieve high sensitivity, selectivity, and long term stability of the devices in corrosive environments at elevated temperatures. Electrochemically synthesized Pd and Au nanoparticles deposited as sensing layers on capacitive field effect devices were found to give a significant response to NOx with small, or no responses to H2, NH3, and C3H6.

9. Gold allergy : In vitro studies using peripheralblood mononuclear cells
Sammanfattning : Positive patch test reactions to gold are commonly seen in dermatology clinics, but it is veryunusual for the patients to actually have any clinical symptoms. It is also common with irritantreactions that are not linked to adaptive immunity. LÄS MER
10. Aberration-Corrected Analytical Electron Microscopy of Transition Metal Nitride and Silicon Nitride Multilayers
Sammanfattning : Two multilayer thin films have been studied: TiN/SiNx and ZrN/SiNx. A double-corrected transmission electron microscope (TEM) was utilized for imaging and spectroscopy. Imaging was carried out in scanning mode (STEM) for all samples. LÄS MER
