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.
Definition of SEER - Seasonal Energy Efficiency Ratio. SEER stands for Seasonal Energy Efficiency Ratio. This is a measure of the energy efficiency of the air conditioning system. SEER ratings permit consumers to compare operating costs of various cooling systems and products. SEER = [Total Cooling Output Over the Cooling Season] / [Total Electrical Energy Input Over the Cooling Season]
