Power, Sample Size, Effect Size: Considerations for Research

Power and Precision •If seeking medium ES, then as bare minimum the desired CI should at least exclude the possibility of values suggesting small and large ES. •For example, ES = 0.5 with CI = (0.15, 0.85) small (0.2) and large (0.8) ES are in the possible range. Thus CI is not precise enough to detect ES of interest vs others.

Oxygenated treatment - Wikipedia

Oxygenated treatment (OT) is a technique used to reduce corrosion in a boiler and its associated feedwater system in flow-through boilers.. With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30-50 ppb. OT programs are most commonly used in supercritical (ie >3250psi) power boilers.
