A swallowable, solid dose form composition for treating upper gastrointestinal tract distress containing bismuth subsalicylate, carbonate or bicarbonate salt, disintegrating agent, anionic or nonionic surfactant, and microcrystalline cellulose is described. Therein, the base member has a flange part that contacts positioning plate of the mounting apparatus, and a fixed part that is urged with a pressing force that presses the flange part to the positioning plate. The expected progression includes a characteristic temporal sequence of a first value and at least a second value that differs from the first value. The electrical probe also includes a low electrical resistivity layer concentrically around the high yield strength wire core. A first ferrule is supported by and extends through the first face of the insert cap.
