1. Integration of MRI into the radiotherapy workflow
Abstract : The modern day radiotherapy treatments are almost exclusively based on computed tomography (CT) images. The CT images are acquired using x-rays, and therefore reflect the radiation interaction properties of the material. READ MORE

2. Energy and intensity modulated radiation therapy with electrons
Abstract : In recent years intensity modulated radiation therapy with photons (xIMRT) has gained attention due to its ability to reduce the dose in the tissues close to the tumour volume. However, this technique also results in a large low dose volume. READ MORE

3. Evolution in changing environments revealed by fire melanism in pygmy grasshopper
Abstract : According to theory, genetic diversity can be maintained by environmental variation and the degree of genetic and phenotypic polymorphism may enhance the ability of populations to endure stress imposed by changing environments. In my thesis I used colour polymorphic pygmy grasshoppers (Tetrix subulata) as a model system to explore how environmental variation influenced genetic diversity. READ MORE

5. Ganglionic nerve fibres in ventral roots
Abstract : According to the law of Magendie, the ventral roots channel efferent nerve fibres from the spinal cord to the periphery, while the dorsal roots channel afferent axons from the periphery into the spinal cord. However, as sensory C-fibres have been observed in mammalian ventral roots outside the autonomic outflow, this law has been questioned. READ MORE
