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.
Stroboscopes are used to measure revolutions, velocity and frequency of rotating components or moving parts. Online you will be able to find stroboscopes by PCE and several other companies. Some stroboscopes can be used without a mains adaptor as they have rechargeable batteries and each model is light and easy to use.
