efficiencies in Science
efficiency
  (ĭ-fĭsh'ən-sē)   
  1. The ratio of the energy delivered (or work done) by a machine to the energy needed (or work required) in operating the machine. The efficiency of any machine is always less than one due to forces such as friction that use up energy unproductively. See also mechanical advantage.

  2. The ratio of the effective or useful output to the total input in any system.
