1. 1. Operations for gastro-esophageal reflux disease. Studies on mode of action and how to improve functional outcomes

   Författare :Cecilia Engström; Göteborgs universitet; []
   Nyckelord :;

   Sammanfattning : Fundoplication operations have gained wide acceptance as an effective and durable treatment for chronic gastro-esophageal reflux disease (GERD). However, further valid data are required on the long-term efficacy and above all the corresponding profile of operation specific side effects. LÄS MER

   Sammanfattning : Background: Subarachnoid haemorrhage (SAH) is a severe stroke that in 85% of all cases is caused by the rupture of a cerebral aneurysm. The median age at onset is 50-55 years and the overall mortality is approximately 45%.Sufficient cortisol levels are important for survival. LÄS MER

4. 3. Wave Power for Desalination

   Författare :Jennifer Leijon; Cecilia Boström; Irina Temiz; Jens Engström; Deborah Greaves; Uppsala universitet; []
   Nyckelord :Wave power; desalination; freshwater; engineering education; linear generator; wave energy converter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : This doctoral thesis presents work related to wave powered desalination. Wave power for desalination could be an interesting alternative for islands or coastal regions facing freshwater shortage, and several systems have been proposed in literature. However, desalination is a process which demands a lot of energy. LÄS MER

5. 4. Wave Powered Desalination

   Författare :Jennifer Leijon; Cecilia Boström; Irina Temiz; Jens Engström; Anna Rutgersson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave power; desalination; marine renewable energy sources; marine current; freshwater; Engineering Science; Teknisk fysik;

   Sammanfattning : The aim of this licentiate thesis is to investigate opportunities to produce fresh-water and electricity using marine renewable energy sources, such as wave power and marine current power, for water scarce areas. It summarizes the ongoing work within the field and suggests some possibilities of future re-search. LÄS MER
