Training of Medical Students for Mass Casualty Incidents Using Table-Top Gamification.

Introduction: "Table-top" exercises can improve knowledge and skills related to mass casualty incidents (MCIs) with little logistical efforts. We aim to evaluate the learning process of 5th year medical school students related to MCI response using table-top simulation and measure their methodology perception.

Methods: A theoretical part plus an MCI simulation board exercise was organized.

Dielectric behavior of ceramic-graphene composites around the percolation threshold.

Al2O3/graphene and BaTiO3/graphene composites with different concentrations of the conductive second phase, both below and above the percolation threshold, were prepared by the traditional ceramic processing route followed by spark plasma sintering. It is shown that the addition of graphene pins the grain growth of the ceramic matrix grains, leading to a change of the microstructure at low filler concentrations. As a consequence, the composites exhibit two percolation thresholds and their dielectric properties are not only determined by the dielectric properties of the constituents and their relative fractions but also the microstructure of the composite must be considered.
