A smoking article, which provides lower amounts of total particulate matter in a latter portion of its puff count, includes a cylinder of smoking material, a combustible hollow tube within the cylinder of smoking material, and a heat sink at a downstream end of the hollow tube. A point-of-presence interactive system is provided, wherein consumers are motivated to provide information. Another aspect of the invention further provides methods and apparatus for controlling the internal body temperature of a patient. The polyamide resin pellet exhibits low water absorption and is excellent in moldability, mechanical strength characteristics and heat resistance. Each torsional member has a free end cantilevered outwardly from the first end of the body and spaced from one another. The system further includes an originating data view retrieving and displaying, via the user interface, a source document corresponding to at least one data element on the graph shown in the thumbnail trend view.
