An antenna unit for a mobile terminal comprises an antenna module rotatably coupled to a terminal body. CO2 or other blowing agent based foaming processes such as extrusion, batch foaming, and injection molding may then be carried out to produce polymer foams that have low density, high-R value, bimodal structures, good mechanical properties, and high fire retardance. In such a case the radio link protocol is set up between the mobile station and the mobile services switching center without a radio link protocol conversion in an interworking unit of the radio access network. The mounting mechanism includes an interlocking mechanism that prevents transfer of the applied force to the rest of the electronics server. The method comprises the steps of administering an effective amount of a receptor antagonist to a subject having one or more symptoms of hormonal variations, wherein the receptor antagonist binds to at least one receptor selected from the group consisting of a serotonin type 2A and a dopamine type 2 receptors.
