Described are injectable formulations of nanoparticulate olanzapine that produce a prolonged duration of action upon administration, and methods of making and using such formulations. The method includes preparing cerium hydroxide by precipitating a cerium salt in the presence of a solvent mixture of organic solvent and water and hydrothermally reacting the prepared cerium hydroxide. The physical link also includes a wireless base station and at least one network address translation router that is configured to terminate idle connections between the client and the web-server. The location computing unit is configured to compute a start point of the changed display area when the display area is changed.
