1. Helicobacter pylori : molecular mechanisms for variable adherence properties
Sammanfattning : More than half of all people worldwide are infected with H. pylori. The infection always cause a gastric inflammation that may develop into peptic ulcer disease or gastric cancer. Attachment proteins, adhesins, mediate specific adherence of H. LÄS MER
2. Mean Wind and Turbulence Conditions in the Boundary Layer above Forests
Sammanfattning : As wind turbines have grown, new installation areas become possible. Placing wind turbines in forested landscapes introduce uncertainties to the wind resource estimation. LÄS MER
3. Helicobacter pylori : molecular insights into regulation of adhesion properties
Sammanfattning : Helicobacter pylori infects the human stomach and triggers an inflammatory response that damages the gastric tissue. This host-pathogen interplay has dire consequences as up to 20 % of infected individuals develop peptic ulcer disease or gastric cancer. LÄS MER
4. Local Effects On Icing Forecasts for Wind Power In Cold Climate
Sammanfattning : This thesis will examine the local effects of land cover on icing forecasts. In Paper I, a single column model was used to test the sensitivity of icing forecasts to land cover fraction. Here, the ice accretion forecast was found to be highly sensitive to the wind magnitude response to the surface roughness. LÄS MER
5. Local Effects On Icing Forecasts for Wind Power In Cold Climate
Sammanfattning : Understanding the risk of atmospheric icing on wind turbines is crucial for the operation of wind farms in cold climate regions. Processes leading to atmospheric icing in the planetary boundary layer are subject to interactions with the land surface--the details of which are largely unknown in current numerical weather prediction models and must be parameterized.
