In the Search of a Performance Measure: How You Measure Success Regarding the search for performance measure for an online course that is definable and measurable on a numerical scale, e-learning system has been already adapted a point-of-sale system to measure its impact on the bottom line. Web course offers opportunities to develop more familiarity with computers and the Web; and it shows the potential of the Internet as an educational resource. The course offers students the opportunity to try a different approach to learning, one likely to become more prevalent in the future.
Albumin accounts for more than 50% of the total serum proteins. The albumin to globulin (A/G) ratio has been used as an index of disease state, however, it is not a specific marker for disease because it does not indicate which specific proteins are altered. The normal A/G ratio is 0.8-2.0. The A/G ratio can be decreased in response to a low albumin or to elevated globulins.
In respiratory physiology, the ventilation/perfusion ratio (or V/Q ratio) is a measurement used to assess the efficiency and adequacy of the matching of two variables:  1 V â ventilation â the air that reaches the alveoli. 2 Q â perfusion â the blood that reaches the alveoli.herefore, under these conditions, the ideal ventilation perfusion ratio would be about 0.95. If one were to consider humidified air (with less oxygen), then the ideal v/q ratio would be in the vicinity of 1.0, thus leading to concept of ventilation-perfusion equality or ventilation-perfusion matching.
