The invention proposes a plumbing fixture block, which has seatings for a mixing device and a shut-off valve. The electronic device includes an attachment member moveably coupled to the metal housing. Such belt may be of pliable construction and may define a predetermined spacing in between adjacent ones of the syringe bodies, such predetermined spacing corresponding with a distance between holders provided in a handling apparatus. The apparatus includes in an alternate embodiment a voice recorder for recording a voice file, wherein the voice file is associated with the data file. Each carbon nanotube can be capsulated in a nanometer-scale metal having a high heat conduction coefficient. Each fin plate includes a plurality of cutouts defined on one edge thereof, and the cutouts of the fin plates cooperatively form a scraggy surface when the fin plates are assembled together.
