| beat-to-beat variability | Variability of foetal heart rate measured in changes in the QRS-QRS interval from heart beat to heart beat; measured with electronic internal foetal heart rate monitors. Continuous variation, a series of very slight variation's. (05 Mar 2000) |
| variability | The state of being variable. (18 Nov 1997) |
| proportional | Being in proportion: corresponding in size, degree or intensity, having the same or a constant ratio, of, relating to or used in determining proportions. (18 Nov 1997) |
| proportional counter | A Geiger-Muller counter operating in the voltage range and under conditions in which pulse height is proportional to the energy of the particles or rays being counted, thus making discrimination between particles or rays of different energies possible. (05 Mar 2000) |
| proportional hazards models | Statistical models used in survival analysis that assert that the effect of the study factors on the hazard rate in the study population is multiplicative and does not change over time. (12 Dec 1998) |
| proportional limit | The greatest stress that a material is capable of sustaining without any deviation from proportionality of stress to strain (Hooke's law). (05 Mar 2000) |
