The present invention relates to an LED module for automobile headlights. The first tube is capable of being rotated by way of a first knob, and the second tube is capable of being rotated by away of a second knob. The system also includes a drive mechanism for driving the plate between a first position in which the hole is at the first location and a second position in which the hole is at the second location. By using this technology, the structural foams have a smaller cell size, a more uniform cell structure, a larger void fraction, less surface swirl, and less weld line contrast. The invention also provides gene therapy methods using nucleic acid molecules encoding the heavy andor light immunoglobulin molecules that comprise the human anti-IGF-IR antibodies.
