Fractures of the coronoid rarely occur in isolation. They usually occur in combination with a radial head fracture, a dislocation of the elbow, or both (terrible triad of the elbow).Large coronoid fractures often are associated with persistent elbow instability even after reduction of the dislocation.
Hydrothermal Vents. Measurement of tectonic plate movements. The amount of tectonic plate movement is measured using Global Positioning System (GPS) satellites and a network of GPS receivers. This technology allows scientists to measure plate movements as small as a few millimeters per year. click here to plot REAL-TIME data and visualize tectonic plate movement.
An accelerometer is a device that measures proper acceleration. Proper acceleration, being the acceleration of a body in its own instantaneous rest frame, is not the same as coordinate acceleration, being the acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's gravity, straight upwards of g â 9.81 m/s2. By contrast, accelerometers in free fall will measure zero. Accelerometers have multiple ...
