A simplified mechanism for feeding a plurality of individual twine strands into a bale forming chamber for wrapping a bale that allows user-selectable adjustment of twine strand spacing along the bale length so that an optimal number of circumferential twine wraps around the bale necessary to secure the bale after discharge from the bale forming chamber may be selected. An excimer laser having operating conditions and a wavelength chosen to selectively melt amorphous silicon irradiates the entire substrate surface and is largely non-absorbed by materials other than silicon when incident upon them. The parameters include at least one multicast group definition parameter and at least one multicast session description parameter. Consequently, the organic EL device has a high efficiency and a long life. A first set of data sequence breakpoints may be determined for the first layer of multiple description coding. The key step involves the resolution of the racemate with mandelic acid.
