CAM", meaning "complementary and alternative medicine", is not as well researched as conventional medicine, which undergoes intense research before release to the public.[174] Practitioners of science-based medicine also discard practices and treatments when they are shown ineffective, while alternative practitioners do not.[6] Funding for research is also sparse making it difficult to do further research for effectiveness of CAM.[175] Most funding for CAM is funded by government agencies.[174] Proposed research for CAM are rejected by most private funding agencies because the results of research are not reliable.[174] The research for CAM has to meet certain standards from research ethics committees, which most CAM researchers find almost impossible to meet.[174] Even with the little research done on it, CAM has not been proven to be effective.[176] Studies that have been done will be cited by CAM practitioners in an attempt to claim a basis in science.

Pure methanol is required by rule to be used in Champcars, Monster Trucks, USAC sprint cars (as well as midgets, modifieds, etc.), and other dirt track series, such as World of Outlaws, and Motorcycle Speedway, mainly because, in the event of an accident, methanol does not produce an opaque cloud of smoke. Since the late 1940s, Methanol is also used as the primary fuel ingredient in the powerplants for radio control, control line and free flight model aircraft (see below), cars and trucks; such engines use a platinum filament glow plug that ignites the methanol vapor through a catalytic reaction. Drag racers, mud racers, and heavily modified tractor pullers also use methanol as the primary fuel source. Methanol is required with a supercharged engine in a Top Alcohol Dragster and, until the end of the 2006 season, all vehicles in the Indianapolis 500 had to run on methanol. As a fuel for mud racers, methanol mixed with gasoline and nitrous oxide produces more power than gasoline and nitrous oxide ...

  • In practice the flow of steam through nozzle is not isentropic, but accompanied with losses which decrease the kinetic energy of steam coming out of the nozzle. (wikipedia.org)
  • The Nozzle converts the pressure energy of the steam into kinetic energy. (wikipedia.org)
  • Any turbomachine extracts energy from high-pressure steam and converts it into shaft work. (wikipedia.org)
  • Modification was carried out on the already fabricated Biomass Steam Turbine in order to improve on the various limitations of the machine which include the poor duration of the power generated, the high startup time, and the immobility of the Steam turbine. (meedoenisgroeien.nl)
