    摘要： Damage to the skin of the annular cowl (11) of the intake duct of a turbo-fan engine of an aircraft by exhausting on to it of hot air used within the cowl for de-icing its leading edge (10) is avoided by channelling spent air through an exhaust duct (15) to an exhaust aperture (21) in the surface of the cowl, and providing a heat shield (23) in the skin downstream of the exhaust aperture (21).

    摘要： Compounds of Formula (I), are provided where T is CHO, COR8, or C(OH)R1R2; R1 and R2 are hydrogen, optionally substituted lower alkyl, CF3, optionally substituted alkenyl, or optionally substituted alkynyl; R3 is hydrogen or optionally substituted lower alkyl; R4 is (CF3)nalkyl, (CF3)n(substitutedalkyl), (CF3)nalkylphenyl, (CF3)nalkyl(substitutedphenyl), or (F)ncycloalkyl; n=1-3; R5 is hydrogen, halogen, CF3, diene fused to Y when Y═C, or substituted diene fused to Y when Y═C; W, Y and Z are C, CR6 or N where at least one of W, Y or Z are C; R6 is hydrogen, halogen, or optionally substituted lower alkyl; X is O, S, SO2, or NR7; R7 is hydrogen, optionally substituted lower alkyl, optionally substituted benzyl, or optionally substituted phenyl; and R8 is lower alkyl, CF3, or optionally substituted phenyl. Methods of preparing and using these compounds for inhibiting beta amyloid production and for treatment of Alzheimer's Disease and Down's syndrome are also described.
