Nevertheless, even if there is no causal relation, it is conceivable that occurrence of herpes zoster could act as a risk marker for subsequent severe disease in vulnerable populations.
When there was only the one, it was conceivable that the occurrence was a cosmic anomaly — perhaps some incredibly rare event that only happens once in a thousand millennia.
The use of a coaxial system could be in itself a conceivable reason for the occurrence of an air embolism.
Given its wide use and occurrence, the conceivable harmful potential of aluminium for negative biological consequences in humans is high.
The existence of such patterns is conceivable, because the co-occurrence of virulence genes is a fundamental requirement for pathogen function and interaction with the host at the cellular level [39].
We conclude that clock shift experiments alone are neither necessary nor sufficient to identify the occurrence of all conceivable uses of solar information in animal orientation, so that a predictable response to clock shift should not be regarded as an acid test of the use of solar information in navigation.
Thus, it is conceivable to expect higher spread-F occurrence percentages by IRI during the sunspot maximum, which, in general, establishes a positive correlation between them (Fig. 2) (Abdu et al., 1992; Subba Rao and Krishna Murthy, 1994).
It is therefore conceivable that education might affect the occurrence of EBDs indirectly [ 18].
Such sudden changes, however, are not those favoured by the Darwinian theory, and indeed the accidental occurrence of such a spontaneous transformation is hardly conceivable.
Indeed, it is conceivable that not all of the factors involved in HUS occurrence in young children are identical to those involved in the diminished HUS incidence in adolescents and adults.
