2. 21. Local Effects On Icing Forecasts for Wind Power In Cold Climate

   Author : Erik Janzon; Anna Rutgersson; Metodija Shapkalijevski; Heiner Körnich; Johan Arnqvist; Alfredo Peña; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meteorologi; Meteorology;

   Abstract : 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.

4. 22. Local Effects On Icing Forecasts for Wind Power In Cold Climate

   Author : Erik Janzon; Anna Rutgersson; Johan Arnqvist; Metodija Shapkalijevski; Heiner Körnich; Ebba Dellwik; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : 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. READ MORE

   Author : Ola Sunnergren; Eva Svanborg; Anders Broström; Jan Hedner; Linköpings universitet; []
   Keywords : ;

   Abstract : Introduction: Obstructive sleep apnea (OSA) is a highly prevalent disorder, especially in populations with cardiovascular disease. Unfortunately most cases with OSA remain undiagnosed. READ MORE

   Abstract : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. READ MORE

7. 25. Predicting postoperative pain. Clinical and genetic studies of relationships between pain sensitivity and pain after surgery

   Author : Anna KM Persson; Anestesiologi och intensivvård; []
   Keywords : Elektrisk smärttröskel; genetik och smärta; smärtprediktion; postoperativ smärta; VAS; smärtkänslighet; smärta efter kirurgi; nålsättning; Perifer kateterisering; Electrical pain threshold; prediction of postoperative pain; pain genetics; pain prediction; postoperative pain; venous cannulation; gender and pain; VCP;

   Abstract : Many patients experience pain after surgery. Postoperative pain may lead to delayed mobilization, persisting pain, and psychosocial distress. Others are given excessive analgesic doses and experience side effects. READ MORE
