prevents
subject			fact

prevents	documentation A very general Predicate. (prevents ?PROC1 ?PROC2) means that ?PROC1 prevents the occurrence of ?PROC2. In other words, if ?PROC1 is occurring in a particular time and place, ?PROC2 cannot occur at the same time and place. For example, innoculating prevents contracting disease. Note that this is a relation between types of Processes, not between instances
	has domain1 Process
	has domain2 Process
	is an instance of BinaryPredicate
	is an instance of IrreflexiveRelation
BinaryPredicate	has axiom (=> (instance ?REL BinaryPredicate) (valence ?REL 2))
IrreflexiveRelation	has axiom (=> (instance ?REL IrreflexiveRelation) (forall (?INST) (not (holds ?REL ?INST ?INST))))
