A wheeled transport vehicle includes a frame with two slidably interconnected frame members. The two level segments can be rotated laterally in the plane of the level so as to be oriented with respect to each other at angles of from 0 to 180 degrees, thus effectively doubling the length of the level. The resource usage and the output are measured to determine a resource usage value and an output value at a first time. The piston, sleeve and pin may be configured to allow the sleeve to release from the piston in response to the shearing of the pin. This complex synergistically inhibits proliferation of synovial cells and suppresses matrix metalloproteinase MMP-9, which is produced by synovial cells, as compared with its constituents, hyaluronic acid and zinc, alone. The diesel engine can operate in pre-mixed charge compression ignition combustion.
