The different grades of the Risser sign give a measure of bone maturity and thus of the skeletal growth to be expected. In Europe, a scale ranging from Risser 0 to Risser 5 defines the grades from beginning ossification to complete fusion of the apophysis to the iliac bone. In the USA, 4 grades are defined.
The Seasonal Energy Efficiency Ratio (SEER) is the standard measure of a heat pump or air-conditioning systemâs efficiency. Essentially, a systemâs SEER rating is its cooling output divided by its electrical input. Thus, the higher the SEER rating is, the more efficient the system will be.
