11. Temperature Gradient Instabilities and Transport in Toroidal Plasmas
Sammanfattning : This thesis focuses on temperature gradient driven modes and their implications for heat and particle transport in toroidal plasmas. Some of the consequences of including an ion impurity species in a model for low frequency electrostatic modes and fluctuation driven transport are discussed. LÄS MER
12. Turbulent impurity transport in tokamaks
Sammanfattning : Nuclear fusion is foreseen as one of the options for future energy production. One of the remaining scientific challenges for establishing the physics basis of future magnetic fusion reactors is to find scenarios where the impurity content in the core can be kept low. LÄS MER
13. Turbulent and neoclassical transport in tokamak plasmas
Sammanfattning : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. LÄS MER
14. Intensive training in group for children with Cerebral Palsy : Evaluation from different perspectives
Sammanfattning : There is a need of more evidence‐based knowledge of different treatment/training‐approaches for children with Cerebral Palsy (CP) to better describe the objectives of interventions, effects on functioning and fulfilment of health care needs. The general aim of this thesis was to evaluate the effectiveness of intensive training in groups (ITGs) with a habilitation approach and a conductive education approach. LÄS MER
15. Turbulent impurity transport in tokamak fusion plasmas
Sammanfattning : With the enormous growth of high performance computing (HPC) over the last few decades, plasma physicists have gained access to a valuable instrument for investigating turbulent plasma behaviour. In this thesis, these tools are utilised for the study of particle transport in fusion devices of the tokamak variety, focusing in particular on the transport of impurities. LÄS MER
