A method and apparatus for creating a statistical representation of a query result that can be performed without executing the underlying query. An air inlet and an air outlet are respectively defined in two ends of the through-hole. Diseases that can be treated by the method include cystic fibrosis, chronic bronchitis, and ciliary dyskinesia. The second end is controlled by a rotatable handle on the applicator main housing. Preferably a pair of such shells are adapted to mechanically, selectively and mutually attach at the peripheral edges thereof to form a container thereby.
