1. Fast wave heating and current drive in tokamaks
Abstract : This thesis concerns heating and current drive in tokamak plasmas using the fast magnetosonic wave in the ion cyclotron range of frequencies. Fast wave heating is a versatile heating method for thermonuclear fusion plasmas and can provide both ion and electron heating and non-inductive current drive. READ MORE

3. Premolar autotransplantation in orthodontic treatment : a clinical and radiographic long-term study
Abstract : Premolar aplasia and avulsed or malformed anterior teeth are common in young people. Using autotransplantation, it is possible to move problems in the dental arches to regions where they are more easy to solve orthodontically. READ MORE

4. X-ray Phase Contrast Tomography : Setup and Scintillator Development
Abstract : X-ray microscopy and micro-tomography (μCT) are valuable non-destructive examination methods in many disciplines such as bio-medical research, archaeometry, material science and paleontology. Besides being implemented at synchrotrons radiation sources, laboratory setups using an X-ray tube and high-resolution scintillation detector routinely provide information on the micrometre scale.

5. Ocular aberrations and visual quality in aspherical and multifocal contact lenses
Abstract : Good visual quality and precise accommodation are required to be able to focus objects at distance and near, and are essential in order to be able to perform most tasks in life. Most eyes are not ideal eyes, i.e., they have different refractive errors which distort the produced image. READ MORE
