...cardiovascular system follows a daily pattern that is oscillatory in nature: most cardiovascular functions exhibit circadian changes (circadian is from the Latin circa and diem, meaning "about one day"). Now, a heart attack depends on the imbalance between increased myocardial oxygen demand (i.e., a greater need for oxygen in your heart) and decreased myocardial oxygen supply - or both. And unfortunately, some functions in the first hours of the day require more myocardial oxygen support: waking and commencing physical activities, the peak of the adrenal hormone cortisol [which boosts blood-pressure and blood-sugar levels] and a further increase in blood...
...expose chronic weaknesses in the FAA. The 110 souls on that flight probably never knew what caused the fire that took their lives. At first, government investigators could not pinpoint the reason for the disaster, either. [It was later found that the fire was apparently caused by dangerous oxygen generators loaded into the cargo bay without being carefully handled according to regulations.] But the tragedy would expose what the FAA had long known: ValuJet was primed for a major crash; its maintenance was slipshod; it had an accident rate 14 times as poor as those of its peers; its managers...
...numbers were stunning: from 1988 to 1990, 833,000 inspections turned up fewer than 4,000 violations. The inspectors issued few warnings or fines and rarely tracked cases or followed up on inspections. Landing gear, oxygen systems and engine controls were checked in less than half the inspections. The engines were inspected only 52% of the time. Yet the FAA insisted it completed thousands of inspections every year. How many were thorough? And what about those that were not completed...
...entire wing and tail assemblies. We would confiscate parts made in basements, garages and weld shops, or from major U.S. manufacturers and from Germany, France, England, New Zealand, Canada, Japan, China, the Philippines, Taiwan or unknown countries. They even showed up on the President's helicopters and in the oxygen and fire-extinguishing systems of Air Force...
Despite Betancourt's obvious charisma and attractiveness, she had not a fig's chance of winning her 2002 campaign for the Colombian presidency at the time of her kidnapping. Her Green Oxygen Party had only one parliamentarian, who came from the area to which she traveled disastrously the day FARC rebels nabbed her. This past week Betancourt has said she does not know yet when she will return to Colombia, or what exactly her role will be. But she clearly has her eye on returning to Colombian politics, having penned a 190-point program while she was a hostage...
