The present invention provides for bola amphiphiles compositions which have more than one lyophilic head group and a hydrophobic moiety capable of hydrogen bonding with other bola amphiphiles. 5 equivalents of a ketocarboxy to produce an intermediate ketocarboxylic ester. This position information is shared with other aircraft over an RF data link. An interface specific metadata associated with the process interface can be determined. In the event the sensed torque is below the minimum, the escalator can be shut down to prevent restart until the failure condition is corrected. Chitosan having a deacetylation degree of 30-90% may be also used for solubilizing ofloxacin suspended in an aqueous media having a substantially neutral pH in any other applications.
