1. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets
Sammanfattning : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. LÄS MER

5. The Importance of Dosimetry and Radiobiology in Nuclear Medicine : Quantitative methods and modelling
Sammanfattning : Nuclear medicine uses radioactive pharmaceuticals for diagnostic or therapeutic purposes. The ionizing radiation emitted from the radiopharmaceutical is partially absorbed within the patient's body and internal dosimetry is the method to estimate the absorbed dose to a tumour or risk organ.
