21. The lubricants are intended to reduce friction to keep heat production  down and keep impurities out of the metals. 22. His earliest experiments on the heat production  of contracting muscles used equipment obtained from the Swedish physiologist Magnus Blix. 23. This will not stop heat production  from fission product decay, which would continue to supply a considerable heat output. 24. Increasing heat production  would push up your body temperature-and taken to superhero extremes that would not be a healthy thing. 25. Radioactive chain reaction and corresponding increased heat production  may progress in parts of the corium if a critical mass occurs locally. 26. :: : Is there some way to relate the global warming effects of greenhouse gas emission to that of heat production ? 27. Originally, a spur of the Louisville and Nashville Railroad led to the building, which used coal transported by train for heat production . 28. Syngas can also be used in heat production  and for generation of mechanical and electrical power via gas motors or gas turbines. 29. See " Investigation of anomalous heat production  in Ni-H systems " . talk ) 19 : 48, 31 October 2011 ( UTC) 30. He also introduced a mathematical model of the rate of heat production  by human tissue as it relates to local blood flow.
