A 5 page paper describing the structure and function of the automobile clutch and suggesting alternative materials that could be used to increase friction for both racing and street applications. Racing clutch manufacturers already are using a ceramic-metal alloy; the paper proposes eliminating the metal component. A ceramic material also is lighter weight, contributing to reduced stress on the engine’s crankshaft as well as on the transmission’s input shaft. Bibliography lists 5 sources.

10 pages in length. The more contaminated man makes his planet, the more frantically he seeks ways to reverse the damage. Historically, toxic soil has been unearthed and redistributed into landfills; tainted sediment has continued to spill into bodies of water, kill the fish and sicken all who eat it; and polluted groundwater has all too often leeched its way into drinking supplies. In short, no method to liberate heavy-metal contamination has proven effective for eradicating its presence - until the discovery of phytoremediation, the process by which green plants are used to break down and/or absorb toxic substances in air, soil, sediment, sludge and groundwater. Bibliography lists 10 sources.
