The invention relates to load balancing the binding creation on a home agent with a mobile node in an IPV6 network. The crank and the gear transmission are coupled to each other. In some examples, efficient techniques are used for selecting elements for computation of interactions according at least in part to a separation-based criterion. When the work roll is placed in the position for grinding, a signal to rotate the roll is sent to the grinding machine, and also operates to advance the cylinder rod. The present invention provides a production process of an \u03b1-hydroxy acid having a step of adding a basic metal to an \u03b1-hydroxy acid ammonium salt to yield an \u03b1-hydroxy acid metal salt and a step of desalting the \u03b1-hydroxy acid metal salt to yield the \u03b1-hydroxy acid. Then, a given voltage is applied between the pair of electrodes to synthesize a compound thin film including the components of the first and the second reactive solutions directly on the porous base material.
