The current embodiment of the present invention is an apparatus for attachment to water or other fluid emitting devices and functions to allow a separate exit for soapy water, or other concentrate-fluid mixture, to drain from the faucet without interfering with the existing, clean water or fluid stream. The composite dielectric sheet is flexible and has a high dielectric constant and high dielectric strength. The metal support disk has a plurality of primary vent apertures and a plurality of secondary vent apertures through its surface. Additionally, macrocyclic molecules, including macrolactones and macrolactams, that are prepared by the macrocyclization methods of the invention are described. If they are in an adjacent arrangement, e. Additionally, indexes may be created on multiple key columns, with the sub_keys being independently sorted in either ascending or descending order.
