梅州做人流前要做哪些准备(梅州打胎 什么时候做) (今日更新中)

For the second time in less than six months, a brand-new Boeing aircraft has crashed just minutes into a flight.All 157 people on board the Ethiopian Airlines flight from Addis Ababa that crashed on Sunday morning have died, the airline has confirmed.The tragedy follows the Lion Air flight that went down over the Java Sea in late October, killing all 189 people on board.There is no suggestion yet as to what caused the latest disaster, and no evidence that the two incidents are linked in causality.What is known, however, is that both flights took place on the Boeing 737 MAX 8 -- a new model recently unveiled to great fanfare by the US aviation giant, that saw its first flight less than two years ago."It's highly suspicious," said Mary Schiavo, a CNN aviation analyst and the former Inspector General of the U.S. Transportation Department. "Here we have a brand-new aircraft that's gone down twice in a year. That rings alarm bells in the aviation industry, because that just doesn't happen."Adding to concerns are some similarities between the two flights. Both were operated by well-known airlines with strong safety records -- but the Lion Air flight went down 13 minutes after take off, while Sunday's Ethiopian Airlines flight crashed just six minutes into its journey.And while the Ethiopian Airlines did not see the wild fluctuations in altitude that the Lion Air flight saw, it did dip and then regain altitude before it crashed."The similarities with Lion Air are too great not to be concerned," Schiavo said.Data from flight recorders awaitedAt the root of October's Lion Air crash was a new safety system installed in the MAX 8 plane, known as the Maneuvering Characteristics Augmentation System (MCAS), that automatically pulls the plane's nose down if data suggests it is at risk.In that flight, the system was responding to faulty data that suggested the nose was tilted at a higher angle than it was, indicating the plane was at risk of stalling.The pilots subsequently engaged in a futile tug-of-war with the plane's automatic systems, trying to reverse a nosedive that should not be triggered so soon after takeoff. Boeing has argued that pilots should have identified the system was in operation, and turned it off."All pilots should have been trained on that function after Lion Air," Schiavo added. "Boeing did something very unusual for any manufacturer -- it sent out an emergency bulletin and told all airlines to make sure they trained the pilots in the shut-off procedure.""This is one of the things that should never be happening after takeoff," Schiavo said.It is too early for conclusions to be drawn as to whether the same issue occurred on the Ethiopian Airlines flight -- but a clue could come sooner rather than later."We will not get a final determination for two or three years, but we will get information from the flight recorders -- which I'm guessing will be fairly easy to retrieve -- in a matter of weeks," said CNN anchor Richard Quest, who specializes in aviation."At the moment, it seems a coincidence" that both disasters occurred on the same aircraft, Quest said. "But I'm guaranteeing to you that the authorities will be examining just how close a coincidence, and whether there are common circumstances between the two," he said."Two brand new planes have crashed from two respected airlines," Quest added. "Ethiopian is a very, very well-run airline. There is no safety issue on Ethiopian Airlines."Possible repercussions for Boeing If investigators do uncover a similar cause of the two accidents, the repercussions for Boeing could be dramatic."The Lion Air flight was a big deal for Boeing, but they managed to overcome it," Schiavo says. "They put out the emergency warning about training, and the industry went on. With the second one, I don't think everybody's going to forget."The MAX 8 could be grounded if a link is found -- either by the company itself, or by governments, though the former is more likely to come first, Schiavo says. "The voluntary basis is always the better way to go -- but it will be expensive for Boeing."Airlines with MAX 8 aircraft in their fleet -- and those with outstanding MAX 8 orders -- are likely to be watching developments closely in the coming days and weeks.According to 4284

General Mills, the maker of Gold Medal flour, has recalled 5-pound bags of its unbleached all-purpose flour for possible E. coli O26 contamination, the FDA announced on Monday. The bags of flour have an expiration date of Sept. 6, 2020. The package UPC is: 016000 196100. There have been no reported illnesses, and General Mills said the recall is out of an abundance of caution. Those with recalled products are encouraged to throw out the flour, and contact General Mills at 1-800-230-8103. The FDA added that all flour should not be consumed raw, and that fully cooking flour kills of E. coli. "Although most strains of E. coli are harmless, others can make you sick. E. coli O26 is a potentially deadly bacterium that can cause bloody diarrhea and dehydration," the FDA said. "Seniors, the very young, and persons with compromised immune systems are the most susceptible to foodborne illness." 909

For the first time since the early 20th century, more people in United States are dying at home than at the hospital, according to a report published in the New England Journal of Medicine on Wednesday.The researchers looked at the number of natural deaths in the United States based on data collected by the 321

Federal regulators head to Capitol Hill Wednesday following weeks of revelations about problems with the fatally flawed Boeing 737 Max, and as the world awaits a software fix and revised training program from the aircraft's manufacturer.The Federal Aviation Administration's current acting administrator, Daniel Elwell, is expected to face questions from lawmakers about how the Max was certified, and what steps will be taken to assure a skittish flying public that the aircraft can safely return to the skies.The Trump administration's nominee for the job, Stephen Dickson, will testify at a separate hearing. Dickson is a former Delta Air Lines executive and military pilot, and has not yet publicly commented on the 737 MAX or its grounding, which occurred days before his nomination was announced. In a Senate questionnaire prior to the hearing, Dickson identified safety as one of his qualifications for and priorities on the job.The FAA is waiting on Boeing to complete a software update for its review. The 737 Max 8 and 9 were grounded worldwide after a second crash in Ethiopia two months ago that investigators have described as appearing similar to an October crash into the Java Sea. Between the Lion Air and Ethiopian Airlines crashes, 346 people were killed.When Elwell testified in late March, about two weeks after the Ethiopian crash, he defended the agency's process for grounding the plane. Other countries that acted days earlier, he said, without the data that the FAA waited for.Since then, news reports have revealed how the FAA certification process allowed Boeing officials with authority delegated from the FAA to certify their company's own work.Elwell will be joined by the agency's executive director of aircraft certification, Earl Lawrence, and two officials from the National Transportation Safety Board, which represents the United States in the Indonesian and Ethiopian investigations.Preliminary reports on both crashes have implicated a flight control system that Boeing designed to operate in the background, making the 737 Max fly like earlier versions of the workhorse jetliner. Maintaining enough similarities between the planes avoided costly pilot training programs, a fact Boeing touted as a selling point.But that computerized stability program -- the Maneuvering Characteristics Augmentation System, or MCAS -- received faulty sensor readings in both the Lion Air and Ethiopian jets, and repeatedly pushed the planes' noses downward, and ultimately into steep dives. The pilots' attempts to overcome it were unsuccessful. As is standard practice, the preliminary reports did not lay blame for either accident.The emergency flight procedure Boeing says pilots should rely on when the system malfunctions has not been substantially updated since the 1960s and is now under FAA review, CNN recently reported.But Boeing admitted its software could be improved to break what it described as links in the chains of events that ended in the crashes.Boeing did not perform a flight test of a scenario where the system malfunctioned, CNN has reported. 3100

I hear Air Canada is moving towards addressing its passengers in a more gender-neutral way, replacing “ladies and gentlemen” with “everyone”. This. Is. Good.— Kate Andrews (@kateality) October 13, 2019 213
