Abstract: Disclosed herein is an apparatus for facilitating enhancing operations of a computer numerical control (CNC) cutting machine, in accordance with some embodiments. Further, the CNC cutting machine comprises a support table, a gantry, a carriage, and a main cutting tool. Further, the gantry is configured to move vertically along a length of the support table and the carriage is configured to move horizontally on the gantry along a length of the gantry defining an operation area on the support table. Accordingly, the apparatus comprises an extension device. Further, the extension device comprises a first end and a second end. Further, the first end is attachable to a carriage housing of the carriage and a tool holder is comprised in the second end. Further, the extension device is configured to extend between two positions. Further, the tool holder is configured for removably holding an auxiliary cutting tool.

Abstract: The present invention provides methods and compositions for the delivery of a biologically active agent to a biological system. The compositions include the active agent and a lyotropic phase and release of the active agent to the biological system is modified by the lyotropic phase.

Abstract: The invention provides a compound containing a head group based on urea, glycerol or glycerate and a tail selected from the group consisting of a branched alkyl chain, a branched alkyloxy chain or an alkenyl chain. The compounds may be used as surfactants to form a lyotropic phase that is stable in excess polar solution.
