1. Cellular effects after exposure to mixed beams of ionizing radiation
Sammanfattning : Mixed beams of ionizing radiation in our environment originate from space, the bedrock and our own houses. Radiotherapy patients treated with boron neutron capture therapy or with high energy photons are also exposed to mixed beams of gamma radiation and neutrons. LÄS MER
2. Om folkhögskolans dynamik : Möten mellan olika bildningsprojekt
Sammanfattning : This study is describing the projects of Bildung which are possible to identify with the students and the teachers at two folk high schools and the meeting between those projects in the classrooms. Another purpose is to describe and analyze processes, which arise when teachers, students and folk high school as an institution come together. LÄS MER
3. Radiobiological investigations of proton and light ion therapy
Sammanfattning : During the last decade, the interest in proton and light ion beam therapy has increased considerably and several new centres are planned around the world. These particles have a large advantage due to their sharp physical dose distributions as compared to conventional radiotherapy beams. LÄS MER
4. Averaged linear energy transfer and other beam quality descriptors inr elation to relative biological effectiveness
Sammanfattning : In radiotherapy with protons, a constant relative biological effectiveness (RBE) of 1.1 is traditionally applied, i.e. protons are assumed to be 10\% more effective than photons in killing cells. LÄS MER
5. Role of Non-Homologous End-Joining in Repair of Radiation-Induced DNA Double-Strand Breaks
Sammanfattning : Efficient and correct repair of DNA damage, especially DNA double-strand breaks (DSBs), is vital for the survival of individual cells and organisms. Defects in the DNA repair may lead to cell death or genomic instability and development of cancer. LÄS MER
