A telecommunication system includes a first type of telecommunication switch and a first server coupled to the telecommunication switch. Specifically, the invention provides methods and materials for determining whether a stool sample from a mammal contains a neoplasm-specific marker from a neoplasm located in the supracolonic aerodigestive tissue of a mammal. Each module may include a heating component disposed between the cover layers and which is configured to convert electrical energy to heat energy and to distribute the heat energy. The first connection surface is inclined relative to a plane orthogonal to central axis directions of the pipe. In an organizer mode, the walls are supported by, and serve to separate the faceplates. The operating lever is operable so as to force the press member to move in the radial inward direction and abut against the tubular bushing, thereby enabling the tubular bushing to frictionally engage the inner leg post so as to resist movement of the inner leg post relative to the outer leg post.
