41. A US listening post was built in Ethiopia to exploit a common ducting of signals from southern Russia. 42. Later models had ducting fitted to the front valance to feed cool air directly to the brake discs. 43. First, attach the end of the insulated ducting to an eight-inch length of galvanized metal duct. 44. The main problem with using flexible ducting is that the ridges throughout the length of the duct catch lint. 45. Classically, moderators were precision-machined blocks of high purity graphite with embedded ducting to carry away heat. 46. The air intake ducting may be designed and shaped appropriately for easy removal of the LM2500 from their ships. 47. These homes often have very high ceilings on the lower level to accommodate the home's HVAC ducting . 48. The FTTP rollout was to gradually replace the exchange space and extensive network ducting to assist in the rollout. 49. It will be easier to attach the insulated ducting to the fan housing before it is mounted between the joists. 50. Finally, the air ducting weighs about 5?to 10?more than an equivalent rocket that gives the same thrust.
