The invention relates to a door module including a detachable panel and configured to wire a door harness. A front portion of the frame supporting the front motorcycle type single steerable wheel and handlebars mounted thereto for conventional steering. The laser radiation is irradiated at an angle of incidence relative to the semiconductor material surface normal of from about 5\xb0 to about 89\xb0, and the laser radiation can be at least substantially p-polarized. The invention is further constituted by a tool arrangement for a dredger. In other embodiments, addressable network resource selection systems and methods may weight linking scores to emphasize desired outcomes, such as encouraging exploration of a network-based site or encouraging high aggregate sales figures.
