Radiobiological compensation of treatment errors in radiotherapy
The British Journal of Radiology, 2008 The linear quadratic model of radiation effect and the biologically effective dose concept can sometimes be used to provide radiobiological compensation for errors that have occurred in radiotherapy dose delivery. The associated mathematics is not complex, but there are important subtleties, which can lead to misunderstanding and erroneous corrections ...

Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.
