1. 21. Platelet Activation and Inhibition in Connection with Vascular Stents

   Författare :Kjeld Christensen; Rolf Larsson; Sten Husted; Uppsala universitet; []
   Nyckelord :Medicine; platelets; inhibition; activation; stents; ACS; Medicin;

   Sammanfattning : This thesis describes the Chandler loop, which makes it possible to conduct studies in vitro of molecular and cellular interactions between whole blood and stents. It was possible to monitor activation and inhibition of the cascades systems, leukocytes and platelets by combining different platelet inhibitors and heparin coating of stents. LÄS MER

3. 22. Grid Connection of Permanent Magnet Generator Based Renewable Energy Systems

   Författare :Senad Apelfröjd; Sandra Eriksson; Frans Dijkhuizen; Uppsala universitet; []
   Nyckelord :VAWT; H-rotor; Tap Transformer; Cascaded H-bridge Multi-Level; Renewable Energy; Wind power; Wave power; Marine Current Power; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : Renewable energy is harnessed from continuously replenishing natural processes. Some commonly known are sunlight, water, wind, tides, geothermal heat and various forms of biomass. The focus on renewable energy has over the past few decades intensified greatly. LÄS MER

4. 23. Grid Connected Three-Level Converters : Studies for Wave Energy Conversion

   Författare :Remya Krishna; Mats Leijon; Karin Thorburn; Uppsala universitet; []
   Nyckelord :Wave energy; power converters; control strategies; grid connection; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : This thesis presents an electrical system analysis of a wave energy converter (WEC) for the objective of grid connection. To transfer the enormous amount of power from waves to the load centers, efficient power electronic systems are essential. LÄS MER

5. 24. Automation of underwater operations on wave energy converters using remotely operated vehicles

   Författare :Flore Remouit; Jens Engström; Antonio Pascoal; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remotely Operated Vehicles; wave energy; WEC deployment; cable connection; optical positioning system; autonomous underwater docking;

   Sammanfattning : In the last fifteen years, the Division of Electricity at Uppsala University has been developing a wave energy converter (WEC) concept. The concept is based on a point-absorbing buoy with a directly driven linear generator placed on the seabed. LÄS MER

7. 25. Development of dementia in older adults : the body-mind connection

   Författare :Giulia Grande; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :dementia;

   Sammanfattning : Over the past years, two major lines have emerged in the field of dementia research that are focused on: (1) The accurate and early prediction of dementia, and (2) The identification of modifiable factors for dementia prevention. This thesis has contributed to both. LÄS MER
