Methods and apparatus, including computer program products, for shaping amplitude contours of musical notes. The printhead integrated circuits are provided in a number and configuration such that the printhead integrated circuits define an elongate printing zone of at least 914 mm. The invention provides a novel method for identifying a nucleic acid or a polypeptide sequence that may be essential for the growth or viability of an organism. One or more electrical conductors are fixed in place, extending through at least a portion of the pole, terminating in an electrical contact for releasable engagement with a cooperating electrical contact mounted to the carriage as the carriage is raised into the elevated position. The particles can also include silicon or germanium atoms or ionized gas atoms including those of hydrogen, oxygen, nitrogen, neon, argon, or krypton. In formula, R1 represents the group \u2014CH2\u2014O\u2014CO\u2014R3 or CH\u2014CH2\u2014O\u2014CO\u2014R3, R2 represents an alkyl radical comprising between 1 and 4 C atoms or halogen, R3 represents an unbranched alkyl radical comprising between 16 and 36 C atoms, m is 1, 2 or 3, and n is between 0 and.
