Compound or open fractures are typically high-energy type injuries which generally occur when an individual is involved in a high velocity car accident or fall- or when a landing is awkward with twisting or torsional type forces.
This type of battery has an unusually highenergy density, which means the units can be smaller and thus lighter for a given amount of power than traditional batteries.
Dr Kobayashi and Dr Maskawa, who were at Japan's HighEnergy Accelerator Research Organisation and Kyoto University respectively, described a type of symmetry breaking that predicted two new families of quarks, a sort of subatomic particle whose simplest members are the ingredients of the protons and neutrons that form atomic nuclei.
