11. The main advantages are its flexibility, low heat production , and ability to machine hard and brittle materials. 12. When temperature moves out of the ideal range, mechanisms kick in to increase or decrease heat production . 13. Your body detects that it's overheating, and lowers your metabolic rate to limit heat production  to fight this. 14. The project involves " improving the efficiency and reliability " of Omskenergo's electricity and heat production , it added. 15. The new form factor of fireplaces suits modern living spaces in both its measurements and heat production  qualities. 16. In the course of a sprint, the heat production  in cheetah exceeds more than 50 % of the normal. 17. In one study ( B�ckman 1990 ), the heat production  rate of T-lymphoma cells cultured in suspension was measured. 18. The share of renewable energy resources in the total fuel balance for heat production  increased to almost 20 %. 19. The power requirements and heat production  of the Pentium make it less desirable in laptops than on the desktop. 20. Heat production  tapers off after dawn as the sun takes over, maintaining the same toasty heat around the clock.
