The causality factors CF-2 and CF-3 are calculated from the frequency spectrum of the current responses.
Crevice corrosion has been investigated by measuring the so-called "causality factors", which are calculated from the ratio of the current components in the ac-response.
The causality factors obtained under different experimental conditions are approximately equal to its theoretical values (2 and 3) indicating that the measured data are valid.
The large peaks [23] function to calculate the corrosion current density (i corr), the slopes of Tafel curves (β a and β c) and corresponding causality factors [CF-2 and CF-3].
Unlike other electrochemical corrosion rate measurements, EFM has the advantage to provide indicating ratios in the current response at different frequencies, so-called causality factors, which allow identifying changes in the corrosion system and therefore assessing the accurateness of the obtained results.
In both cases (before and during the stimulus), the curves are indistinguishable and the causality factors are low.
Previous evidences suggested that the causality factors are likely to be multiple and leukemia subtype-specific, combining both genetic susceptibility and environmental exposures [ 17].
These gaps will be critically analysed, looking at causality factors that result in children affected by AIDS losing their privilege as rights' holders and assuming new roles as duty-bearers amongst other issues.
Instead of using solely the causality factors as potential predictors of being an emergent safety signal, they pragmatically used the different aspects of strength of evidence based on report quality and content.
Previous researches demonstrated that for some childhood leukemia types the causality factors are likely to be multiple and associated with leukemia subtype-specific, combining environmental exposures and genetic susceptibility modulation risk [ 11, 12].
The term 'Causality' includes risk factor, predisposing factor, precipitating factor, causation and reinforcing factor.
