The present invention refers to a process for the resolution into one of its enantiomers of the racemate of compound of formula :which comprises separating said one of its enantiomers from a diastereoisomeric salt of formula, which is formed by reaction of the racemic mixture with an optically active acetylated amino acid of formula. According to one exemplary embodiment of the present invention, a modular camcorder includes a digital video camera unit and a portable multimedia player modular unit. The rinsing step can be completed while the substrate remains on a polishing pad of the apparatus, or, alternatively, the substrate can be removed to a rinsing chamber for rinsing. Adequate SPLs are provided when the ear is not sealed to the device by the combined use of distal and central ports. The trading application determines a linear spread price axis, at which price levels are separated by consistent linear tick increments.
