The invention presents an external preparation for allergic diseases containing 3\u2032-hydroxymethyl-4-hydroxypyrrolido1,2-f2\u2032,5\u2032-pipera-zinedione as an active ingredient. The delamination of the doped layer from the dielectric layer is stopped when the defect propagates into an interface between the doped layer and the dielectric layer that has an adhesive energy that is greater than the strain of the metal layer. The feedback path is connecteddisconnected according to the level of the control signal M from outside, thereby switching the number of divisions. The online tournament format also allows participants to start playing match in a round of the tournament prior to the official start of that round. The radiation emitter device may further include a secondary reflective cup, preferably a parabolic or elliptical reflective cup, disposed proximate the encapsulant about the periphery of the Fresnel lens structure. The invention further relates to a control unit for a cooking appliance for carrying out such a method, and to a cooking appliance comprising such a control unit and at least one core temperature probe.
