content due to oxidation, although raisins cured indoors maintain higher
levels. A review in the "Journal of Food Chemistry" in January 2010 reported

Technology to precisely anticipate the "clear air turbulence" likely to
blame for both flights just doesn't exist, experts say.
The first incident occurred on Monday, when United Airlines flight about to
land at Billings, Montana, was rattled by sudden ... 阅读全帖 |
