The invention provides fluororesin fiber paper excellent in adhesion to a copper foil, heat resistance, chemical resistance, low water absorption and electric insulation and capable of being used as a substrate of a printed board suitable for use in high frequency, of which a low dielectric loss is required. Said cerium doped magnesium barium tungstate luminescent thin film exhibits high luminescence efficiency and high light emitting peaks in red and blue regions. Preferably the method of the invention operates dynamically and during run time. When the solid-state imaging device is attached to the optical unit, the center of the light-receiving elements is determined as a reference position. Methods for use of such antibodies in the detection of HIV-1 infection are also provided. The suspension has a load bolster supporting the sprung weight at a ride height and a rebound member between the sheel axle support and the chassis.
