Ryzner scale index

WebThe PSI index is calculated in a manner similar to the Ryznar stability index. Puckorius uses an equilibrium pH rather than the actual system pH to account for the buffering effects: PSI = 2 (pH s) - pH eq Where: pH s is the pH at saturation in calcite or calcium carbonate pH eq = 1.465 x log10 [Alkalinity] + 4.54 WebJan 25, 2012 · The mean Mini-Mental State Examination (Folstein, Folstein, & McHugh, 1975) scores for this group was 25 with a range of 16–30, and a mean RBANS Total Scale Index score was 68. In this sample, 31% of the sample obtained an EI above the suggested cutoff, and overall cognitive ability was correlated with EI scores.

Scaling Tendency is the saturation ratio after all potential solids come to equilibrium with water. This is the true equilibrium condition (time=∞). I Pre-scaling Tendency represents the condition before any solids are allowed to form.

The higher the score (ranges from 0 to 58.2) the higher the functional status. VO 2 peak (mL/kg/min) = 0.43 x DASI + 9.6. METs (metabolic equivalents) = VO 2 peak / 3.5. Best METS performed can also be used to predict functional capacity. WebRyzner, J.W. (1944) A New Index for Determining Amount of Calcium Carbonate Scale Formed by a Water.
