The invention features methods of treating visceral pain in humans by administering an effective amount of a 5HT1B or 5HT1D receptor agonist,. The method steps include shaping followed by solution annealing between 1200 C. The HVAC unit provides an inserted deflector means which provides for smaller packaging volume, allows air deflection and airflow towards the distribution area of the unit, and, provides a drainage means for undesired water, before it reaches the distribution area, yielding an HVAC unit, with the same functionality as larger HVAC units. An external collector can thus proceed with traffic profiling or other flow monitoring purposes with a more intelligently determined network flow sample. The extruded profile comprises a first edge portion extending along a first edge of the glazing, a sharp corner portion extending around a sharp corner of the glazing and a second edge portion extending along a second edge region of the glazing, the portions of the profile being continuous.
