Woodworking machines are disclosed having cutting tools for cutting workpieces. The compounds have an affinity for the \u03bc-opioid receptor and may take the form of the racemate; enantiomers, diastereomers, mixtures of enantiomers or diastereomers, an individual enantiomer or diastereomer, a free base, or a salt with a physiologically acceptable acid. The gas-phase fluorination can be carried out statically or dynamically. And, the datagram is forwarded from the gateway network to the network element that is responsible for forwarding of datagrams to the mobile node.
