The present invention is directed to novel 4-alkyl 1-benzene compounds and a method of improving, enhancing or modifying a fragrance formulation through the addition of an olfactory acceptable amount of the novel compounds. The electromagnetic coil may be disposed in a stationary position with respect to a housing and may be configured to actuate the collar. To ensure proper positioning within the borehole, the sonde is anchored against the borehole wall using at least two of the pads or using a separate anchoring means. The semiconductor manufacturing processes include steps for post etch residue, photoresist removal and steps during chemical mechanical planarization and post chemical mechanical planarization. The selection includes one or more of a subcutaneous standard program, a subcutaneous program without meal boluses, a meal-by-meal subcutaneous program without carbohydrate counting, a meal-by-meal subcutaneous program with carbohydrate counting, and a subcutaneous program for non-diabetic patients. Distal-end ports or perforations are in the symmetrically arrayed walls of a triangular section of the tube which at least characterizes the region of tapering section and which conforms with the triangular-shaped space between the vocal cords, for added ease of insertion into the patient’s trachea.
