1. 11. A Novel Immersed-Boundary Method for Multiple Moving and Interacting Bodies

   Författare :Andreas Mark; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-structure interaction; DNS; immersed-boundary method;

   Sammanfattning : This thesis describes the development, implementation and validation of an implicit, second order accurate, finite-volume and instationary immersed-boundary method for simulating the detailed flow around multiple arbitrary moving and interacting bodies. The potential for flows including moving bodies or boundaries, such as multiphase flows still has to be fully realized. LÄS MER

3. 12. Methodological aspects on carotid artery intervention

   Författare :Magnus Jonsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :carotid artery stenosis;

   Sammanfattning : In Sweden, approximately 25000 patients suffer a cerebral infarction (stroke) annually. Stroke ranks as the third-leading cause of death, and is the leading cause of functional impairment. Carotid artery stenosis accounts for approximately 15% of all strokes and almost all of these are theoretically preventable. LÄS MER

4. 13. Validation and clinical implementation of an MRI-only prostate cancer radiotherapy workflow

   Författare :Emilia Persson; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The radiotherapy workflow for prostate cancer is associated with systematic uncertainty stemming from the registration between the computed tomography (CT) and magnetic resonance (MR) images. A radiotherapy workflow based solely on MR imaging (MRI), called an MRI-only workflow, has been suggested as a means of eliminating this uncer¬tainty. LÄS MER

5. 14. Injuries, risk factors, consequences and injury perceptions in adolescent elite athletes

   Författare :Philip von Rosen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Injury and health data are not fully explored in adolescent elite athletes, yet essential for understanding injury risk, consequences of injuries and developing injury preventive programs. Aims: To explore injury patterns, training and health variables, such as nutritional behaviour, self-esteem, self-perceived stress, sleeping habits, as well as identify risk factors for sustaining a sport injury among adolescent elite athletes.

7. 15. Electronic structure and optical properties of PbY and SnY (Y=S, Se, and Te)

   Författare :Nilton Souza Dantas; Clas Persson; Natalia Skorodumova; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : Lead chalcogenides and tin chalcogenides and their alloys are IV−VI family semiconductors with unique material properties compared with similar semiconductors. For instance, PbY (Y = S, Se, and Te) are narrow-gap semiconductors with anomalous negative pressure coefficient and positive temperature coefficient. LÄS MER
