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 an electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the change in velocity, or speed divided by time.
