Nuclear discharges to the oceans have given rise to significant accumulations of radionuclides in sediments which can later remobilise back into the water column. A continuing supply of radionuclides to aquatic organisms and the human food chain can therefore exist, despite the absence of ongoing nuclear discharges. Radionuclide remobilisation from sediment is consequently a critical component of the modelled radiation dose to the public.

In the posttreatment setting, incidence of TEF in cases with preceding airway invasion (T4b) are not infrequently reported; however, for those for whom disease was confined to organ (T1-3) at staging, this is a rare complication. Management for these cases is palliative in nature, with the goal to prevent aspiration by closing the connection and facilitate safe resumption of oral intake where possible.

Structured repeated practice and feedback for ECGs is likely not provided to most medical students, so skill development is dependent on opportunistic training during clinical rotations. Our aim was to describe: the amount of deliberate practice completed for learning ECG rhythm strip diagnoses in first year medical students, the learning curve for rhythm strip diagnosis, and student experiences with deliberate practice.

Being a radiologist, it is important to keep patient's previous surgical interventions in mind as it can change the management options.

Some methods are simply adapted from other scientific disciplines and can effectively be used to rapidly prepare complex materials for subsequent analysis. A novel sample fusion method is developed, tested, and validated to produce homogeneous, flux-free glass beads of geochemical reference materials (GRMs), uranium ores, and uranium ore concentrates (UOC) prior to the analysis of 14 rare earth elements (REE) via laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS).
