梅州多少天之内做人流(梅州可视流产术价钱) (今日更新中)

Lisa Kendall and Doug Spainhower have spent years, along with their neighbors, working to make their neighborhood more safe from wildfires.“The less burnable material that you have, then the more likely your house is to survive a wildfire," said Kendall.They’ve been clearing the area around their entire neighborhood in the Rocky Mountains of Colorado, which has one road in and out and is surrounded by forests, with dead trees, downed trees and debris.“You have this home, you paid money for it, it only costs a little bit more to do this defensible space work to give these firefighters a chance to be able to defend your home,” she said.“I’ve been right in the middle of forest fires, so it scares the hell out of me,” Doug Spainhower said. He grew up in Northern California, another hot spot for wildfires.“It’s important that everybody is on board because if only half of the residents buy into it, then the other half doesn't, well if their house catches on fire and you’re next door, your house is going to burn down too. There’s no two ways about it,” Spainhower said.“Recognize it can happen to you,” Kendall said. “Even all this preparation and all this work we’ve done over the years, it’s not a guarantee.”2020 has been one of the worst wildfire seasons on record in the western U.S., from winery-scorching blazes in Northern California to 100,000 acres burned in 24 hours by the East Troublesome Fire in Colorado, to fires biting at backyards in Southern California. Oregon and Washington have seen a number of fires this season too, among other states. All leveling homes and putting entire neighborhoods at risk.“As the west has developed and we have seen communities grow that are on the edge of the forest or surrounded by natural wooded areas, we have complicated the problem of wildfire and the threat wildfire poses to people's homes, our communities,” said Steve Lipsher, Community Resource Officer for Summit Fire & EMS. “Mitigation is our way to try to claw back a little bit and protect those areas.”Mitigation efforts include reminding land owners of defensible space, to clear cuts of trees down in conjunction with the forest service.“We’re all working towards this idea of a fire resistant, fire adapted community. One that can withstand a fire. We’re not there yet,” Lipsher said. “But I think we have made some truly innovative strides.”An example lies just north of Downtown Frisco, where Summit Fire & EMS is located. Lipsher said they completed a controversial clear cut around a neighborhood as a precaution, but that cut played a part in saving those homes from the Buffalo Mountain Fire in 2018.“It was a human-caused fire,” Lipsher said. The fire burned up to just a football throw from nearby homes. “When this fire started here, [the clear cut] was the saving grace for this neighborhood,” he said.Scorched trees are still standing today.“We’re seeing some unprecedented fire behavior and some really extreme fire behavior that, as a forester and a firefighter, we just haven't really seen in our lifetime managing these forests,” said Ashley Garrison, a Forester with the Colorado State Forest Service. “The effect these wildfires can have on the environment can really have these cascading event when they are these intense, large fires.”Garrison and Lipsher are just two of the men and women who spend their days working on wildfire mitigation, something Summit County has been focused on for more than a decade.“It’s been 15 years now since Summit County developed one of the first community wildfire protection plans,” Lipsher explained. “It was one of the first developed in the state and in the country.”As for making a community fireproof, that may be unachievable. “Quite frankly I think that will probably be a never ending quest,” he said. “Our existential threat here is wildfire. It's no different if you lived in Kansas with the threat of tornadoes, or if you lived in Miami and it’s the threat of hurricanes.” 3981

LAKE ARTHUR, La. — Hurricane Delta's winds are so strong they are pulling away shingles from L'Banca Albergo Hotel, an eight-room boutique hotel in the Louisiana town of Lake Arthur.WATCH RECAP:“I probably don’t have a shingle left on the top of this hotel,” said owner Roberta Palermo. She said the electricity was out and, across the street, she could see pieces of metal coming off the roof of a 100-year-old building. Unsecured trash cans were flying around on the streets.Palermo is a long-time Louisiana resident who has grown up with hurricanes. “It’s been a long time since I’ve ridden one out. I don’t think I’ve ever been in one like this,” she said. “I think my building is pretty safe but it’s intense, for sure.”One of her guests was Johnny Weaver, a meteorology student from San Francisco State University. He was living at home in Tampa, Florida, while studying online and decided to travel to the region to see and study the storm firsthand.“There is a lot of power lines down all over the place, there’s ... really deep water in certain spots,” he said from the hotel’s front porch, adding, ‘’there is just shingles flying everywhere."According to the National Hurricane Center, the storm made landfall at 6 p.m. CT near Creole with maximum sustained winds of 100 mph. 1293

LA POSTA RESERVATION, Calif. (KGTV) - A local Native American tribe is considering its legal options after one of their sacred sites was vandalized. At least 5 rocks in an area used by the La Posta Band of Mission Indians’ ancestors were spray painted over the weekend.“A lot people don’t understand they’re on the reservation here,” said Victor Estrada, Vice Chairmen of the La Posta Band of Mission Indians. La Posta Reservation is about 50 miles east of San Diego and was blanketed by snow last week prompting visitors to make the trek out to the high elevation to see it. “You can come out here and play in our snow, but don’t destroy our stuff,” said Estrada, “don’t spray paint your name and your family and say 'hey you were here.' We understand you were here, we know you were here.” Estrada says they found out who may have vandalized it through social media and that the tribe may prosecute, but would be open to the offenders cleaning it up themselves. Those claiming responsibility wrote a statement to 10News saying in part: “We are truly sorry as we were not aware that we were on sacred or tribal lands. My husband will be going up this weekend to clean up the writing on the rocks.” 1206

Last year's seasonal flu vaccine effectiveness was just 42%, the US Centers for Disease Control and Prevention estimated. Even if vaccinated, then, people had inadequate protection against the flu.This limited effectiveness was due to a mutation that occurred in the influenza A (H3N2) vaccine strain, according to a new study published Monday in the journal Proceedings of the National Academy of Sciences. This vaccine mutation resulted from an egg-based manufacturing process commonly used today.This year's flu vaccine may also be imperfect, said Scott Hensley, author of the new study and an associate professor at the University of Pennsylvania. Add to that, he said, "this could end up being a pretty bad flu season."Still, he said, "our best protection" against severe illness is getting vaccinated with the flu shot we have today.Finding answersEach year before flu season begins, a vaccine is made based on whichever virus strains are expected to circulate. The selected seed strains are distributed to vaccine manufacturers which then produce their formulations and make them available to health care professionals before the season begins.During the 2015-16 season, vaccine effectiveness was 47%, while for the previous 2014-15 season, effectiveness was just 19%, according to the CDC. While the overall effectiveness of last season's vaccine was 42%, it was only 34% effective against the H3N2 viruses that dominated the season.Vaccine effectiveness varies based on how well it matches the circulating virus strains. Sometimes, a vaccine corresponds to the predominant virus yet its effectiveness is still not what scientists would expect. Trying to understand which element of the vaccine failed is difficult.Hensley and his team began their investigation of last year's vaccine by looking at the seed strains that had been distributed to vaccine manufacturers. These seed strains had been propagated in chicken eggs, the common method used today."The sequences of these viruses are available and when we did an alignment to see what the sequence of these vaccines were compared to the viruses that were circulating, it became very obvious that there was this mutation," said Hensley.To see the effects of the mutation, the team next looked at how the immune systems of both animals and humans who'd been inoculated with an egg-based flu vaccine responded to the actual circulating viruses.The antibodies -- immune system proteins that fight invading pathogens -- elicited in both animals and humans failed to bind to and neutralize the flu viruses, Hensley and his colleagues found.While most vaccines in the United States are made in chicken eggs, a small fraction are produced in insects or mammalian cells, Hensley explained. (These are given to people with egg allergies.) He and his team compared immune responses in animals and humans who had received a cell-based vaccine -- in this case, Flublok made by Protein Sciences Corporation."And we found both animals and humans receiving that (cell-based) vaccine had superior antibody responses that could bind and neutralize these circulating H3N2 strains," said Hensley.Making a better vaccine"Most of the infrastructure to produce vaccines in the US is based on chicken eggs," said Hensley. There are good reasons for this, including the fact that egg-based propagation allows manufacturers to quickly produce large quantities of vaccine.While egg adaptations have always been a problem, beginning last year it had become a "huge problem," said Hensley. "As soon as you try to grow this virus in eggs, within a few hours, the virus will acquire this kind of mutation."This is not an easy problem to fix, he said. To produce vaccines in cells means "a very expensive process for companies to just change their overall manufacturing process," Hensley explained. "You can't really do that on the drop of a dime."Meanwhile, the same seed strains used last year are being used this year to make the current vaccine, said Hensley."This year may be especially difficult because, in addition to this egg adaptive mutation which was present last year, there's indication that the H3N2 viruses are actually evolving," said Hensley.Not only will the vaccine be a mismatch with the actual circulating viruses due to egg adaptation but the vaccine could also be a mismatch due to unexpected viral evolution.What kind of flu season is ahead?It's too early to speculate which viruses will become dominant in the United States over the course of the coming flu season, said Hensley, "but it's starting to look like it will be H3 viruses." H3 viruses are influenza A viruses."There are the A group of viruses and the B groups," said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University. "The A groups are the ones that usually are responsible for large epidemics ... whereas the B flu strains usually smolder along. They always cause illness -- it can be just as severe as the A strains -- but they don't produce large outbreaks."Though last year's vaccine was mostly ineffective in thwarting the flu, it still prevented nearly 30% of hospitalizations that might have resulted, according to CDC calculations. For older adults, that rate was even higher, at 37%. Plus, the vaccine reduced outpatient visits by 42% last season.The CDC advises everyone 6 months and older to get a flu shot, as only injectable flu vaccines are recommended. More than 130 million doses of flu vaccine have been distributed so far this year and flu activity is still low across the nation.It's still early days, but experts believe we may be facing a tough season, and not only because of vaccine concerns.The reason?Australia had a tough flu season this year, with a total of 215,280 laboratory-confirmed cases and 504 flu-associated deaths reported to its National Notifiable Diseases Surveillance System as of October 13, government data show. According to a surveillance system report, adults over the age of 80 and children between 5 and 9 years old have been most affected."In general, we get in our season what the Southern Hemisphere got in the season immediately preceding us," Dr. Anthony Fauci, director of the United States' National Institute of Allergy and Infectious Diseases, said in an interview last month.An "intelligent guess," therefore, is that the Northern Hemisphere, like the Southern Hemisphere, will likely battle more cases of the viral infection, he said, though "with influenza, it is never 100%.""If H3N2 viruses dominate the US flu season again this year, vaccine effectiveness will likely be moderate to low again," said Hensley.Still, he said, everyone should get their annual flu shot."The other components of the vaccine, like H1N1 and influenza B, will likely provide excellent protection," said Hensley. "The vaccine will also likely prevent severe disease and death caused by H3N2 viruses, even though this component of the vaccine is mismatched."  6969
