Provided are methods for producing a high strength, but easily deformed, polystyrene foam board that can endure repeated deformations from its original configuration into more complex curved shapes without damaging the board integrity or substantially reducing its structural strength. A nonlocal streaming resource is replicated in a local network as a local multicast resource. Shear force scraping damage is prevented by a sleeve apparatus. The third lens element has negative refractive power. The conductive line can be electrically coupled to the conductive element on the side surface of the SSID. In the television tuner, in a first mode where the VHF-side block is connected to the mixing circuit, a first terminal, to which the unbalanced output is applied, is coupled to a first input terminal of the mixing circuit, and a second input terminal of the mixing circuit is grounded.
