1. Drift ballooning and ITG instabilities in tokamak plasmas
Sammanfattning : A major aim in fusion research is to understand, predict and control confined plasma instability in terms of equilibrium, stability and transport. Substantial progress has been made in recent years in understanding stability and transport in terms of MHD instability and drift wave instabilities. LÄS MER
2. Regulation of vascular function by fluid mechanical forces. Development of a new vascular experimental platform for integrative physiological and molecular biological studies of living conduit vessels
Sammanfattning : The vascular endothelium is a multifunctional interface between blood flow and target organs and is continuously exposed to fluid mechanical forces such as shear stress, compressive, and tensile forces. Both in vivo and in vitro data indicate that biomechanical forces exert important modulating effects on key vascular functions. LÄS MER
3. Analysis of geometrically modified adhesive joints in steel beams strengthened with composite laminates
Sammanfattning : The use of bonded FRP laminates to strengthen and upgrade existing structures has attracted a great deal of attention during the past two decades. The attractiveness of this method is mainly due to the superior material properties of FRP laminates such as high strength and stiffness, as well as advantages associated with the bonding technique, such as ease of application and good fatigue performance.

4. A Study of the Swirling Flow Pattern when Using TurboSwirl in the Casting Process
Sammanfattning : The use of a swirling flow can provide a more uniform velocity distribution and a calmer filling condition according to previous studies of both ingot and continuous casting processes of steel. However, the existing swirling flow generation methods developed in last decades all have some limitations. LÄS MER
5. Glass mat reinforced thermoplastics - material, process and selected applications
Sammanfattning : The work presented in this thesis covers the processing of glass mat reinforced thermoplastics, GMT, and the mechanical properties of this material group. The thesis evaluates the possibilities of the material group from a processing and mechanical properties point of view. LÄS MER
