The invention provides a stevia formulation comprising a stevia sweetener with a rebaudioside A content of 95% or greater, and 0. The handle includes an elongated inner core having a longitudinal axis, a transverse axis, a front end, a rear end and first and second opposite surfaces extending from the rear end to the front end of the inner core along the longitudinal axis of the handle, the blade being securely mounted to the front end of the inner core. An action profile database is coupled to the event recognition engine. Real-time APs are given priority over non-real-time APs in order to ensure that real-time traffic meets bounded end-to-end delay requirements. The catalyst temperature measurer is installed in each of a part of the plurality of reaction tubes, and the measurement positions thereof are differentiated from each other in the longitudinal direction of the reaction tubes.
