51.   It had once captured condensation dripping from ventilation and cooling systems around a graphite research reactor and the main reactor at the laboratory, Ms. Rowe said.

52.   It will be at least another year before a second shuttle mission can restore the infrared camera with a new cooling system.

53.   Keep your tire pressure correct and your cooling system maintained.

54.   Late next month, Tsibliev and Lazutkin plan spacewalks to install fixtures for a new cooling system, whose parts were also flown to Mir by the shuttle.

55.   Likewise, at some point the refrigerant will leak from the cooling system and bleed out into the atmosphere.

56.   Millions of young fish are inhaled by cooling systems that use river water, he said.

57.   NASA officials said this configuration should greatly reduce the odds of debris or other particles damaging the cooling system and reducing the duration of the mission.

58.   Neglected cooling systems, carbon buildup in the combustion chamber, and marginal or nonfunctioning emission control systems can cause an engine to run hotter.

59.   Over time, engineers also managed to reduce the size of cooling systems and make them physically and economically feasible for use in smaller buildings.

60.   Petkus, of Unicom, said a district cooling system is best suited for large buildings and may not be cost-efficient for smaller structures.
