pushing researchers to extend
And there have been a small number of cases of people dying from Mers who have no known relationship with camels.
"We do have these sporadic cases where there is no known exposure to known cases and we question where do they catch the virus," he told BBC News.
"In some cases there was animal contact or camel contact but in others not, so there is no clear definitive picture yet."
Dr Briese says that other species, including goats and sheep, have been tested but haven't shown antibodies indicating exposure.
Another report showed that the geographic distribution of the disease in camels is far more widespread than previously thought, with significant reservoirs in Nigeria, Ethiopia and Tunisia.
Adding to the Mers mystery, there have been no reports of people dying from the respiratory infection in these areas preamp.
These unknowns, says Dr Briese, are pushing researchers to extend the search for the Mers coronavirus to domestic animals
The virus that is circulating in humans is the same as the one found in camels 牙齒矯正
"The others that we are looking into or are trying to look into are cats, dogs - where there is more intimate contact - and any other wild species we can get serum from that we are not currently getting."
The issue of how to tackle Mers will be on the agenda here in Paris, at the congress of the world organisation for animal health (OIE).
Addressing this meeting of veterinarians and ministers, the head of the World Health Organization (WHO), Dr Margaret Chan also struck a note of caution on the role of camels in the spread of the disease.
"Our current concern, of course, is about the human cases of Mers. I thank OIE for a very balanced scientific assessment on the possible role of camels in the transmission cycle.
"The evidence, however, is by no means conclusive and we need to know this as we issue advice to the public."
One of the biggest worries about Mers is that the virus will mutate and become more easily spread among humans. So far there is no evidence that has happened.
"It can happen at any time - mutations occur randomly," said Dr Briese.
"The larger the numbers the higher the probability. That's the point of trying to stem these human infections."

kidnapped from her Utah bedroom
Elizabeth Smart, who was kidnapped from her Utah bedroom at 14 and held captive for nine months, told The Associated Press that outsiders cannot know what victims are going through and should not question why the woman didn't escape sooner.
Smart, now 26, faced similar questions after her 2002 ordeal. She was repeatedly sexually assaulted and her captors moved her around Utah and California while threatening to kill her family if she tried to save herself.
"We don't know what these evil people are holding over them — whether it's their families' lives, their lives, whatever it is," Smart said. "We just don't know."
A prominent psychiatrist who helped define Stockholm syndrome, in which victims of abduction begin to sympathize with their captors, said determining why a victim resists possible escape even when an opportunity is available is not an exact science.
Dr. Frank Ochberg said the relationship can sometimes involve a "trauma bond," whether it's a physically abusive marriage or a kidnapping situation.
People in this situation become "infantilized, dominated. They end up being attached to the person who dominates them, much like a child," Ochberg said.
Small gifts of kindness from a captor, such as a bit of food or a trip to the bathroom, can create positive feelings within the victim gucci handbags sale.
"Someone takes away the fear, the isolation, and we have positive feelings," he said. "That could be the beginning of a trauma bond Tai O Cable Car."
In other cases, it can be more rational. "They know the risks of escape, and they don't want to take the risk," Ochberg said 娛樂預測.

刺骨的寒風轉瞬即逝
今天是母親節。是一個我們所有人表達對母親感恩的日子。無論你是陪伴還是懷念，都是人世間最感動的情感。
今天，京城的天空一直下著細雨，淅淅瀝瀝的從清晨到現在，綿綿不斷。我想，這也許是老天爺被我們的人間溫暖和真摯情感所感動的淚水吧？或許也是老天爺在試探我們，是不是有可以擋住我們去陪伴和想念媽媽的羈絆？我是讓老天爺失望了，莫說是這點細雨了，即便有再大的風雨，抑或暴雪，也不能泯滅我與媽媽共度快樂時光的心願！
媽，時間過得太快了！
為什麼快樂和美好總是轉瞬即逝Table For Six？
媽，和您在一起，我感到最快樂姻緣配對。
即使吃的是粗茶淡飯，可是我的嘴裏和心裏卻是甜美無比！
媽，他們說女兒我是您的小棉襖Dating Service。
可我覺得您是女兒我的羽絨服，可以抵禦最刺骨的寒風！
媽，我好想時間慢一些的走啊。
這樣，您就會一直如此的快樂著，我也不會變老！
媽，我好留戀我們在一起的快樂啊！
就讓它永遠定格在此，直到永遠！

pass-rusher and on special teams
kgienk245gew The best-case scenario for Sam was to find a team that could use him as a situational pass-rusher and on special teams. At 6-foot-2 and 261 pounds, he doesn't have the size to be a full-time defensive end or the athletic ability to play outside linebacker in the NFL. Sam joins a team that is flush with talented linemen (including first-round pick Aaron Donald) on a rapidly improving defense. If Sam can find a spot in a defensive end rotation that includes Chris Long and Pro Bowler Robert Quinn, he'll have ample opportunity to showcase the pass-rushing skills that resulted in 11.5 sacks last fall.
Special teams will offer even more chances for Sam to find his niche. It was difficult to find anybody at Mizzou's pro day who didn't rave about his resilient nature, which is what separates remarkable special-teamers from ordinary ones. Special teams happens to be an area in which Fisher loves to find hidden gems. Sam's ability to cover kicks or play on return units will go a long way toward deciding if his career starts off on the right foot.
The best news for Sam is that he finally has what he wants. It's impossible to know everything that was churning through his mind as the draft neared its conclusion, but fear had to be part of his thought process. It took 249 picks before Sam's name was announced at Radio City Music Hall. By that point, only a smattering of observers remained.

Mention vuvuzela may cringe
Mention 4gewe3g6edge vuvuzela to soccer fans, and they may cringe. The plastic horn rose to prominence during the 2010 World Cup in South Africa, where tens of thousands of those instruments blared in packed stadiums. The loud, buzzing noise soon became a major annoyance, disrupting players and even fans watching on TV. Now, for the 2014 World Cup in Brazil, organizers have introduced the maraca-like caxirola as the official instrument of the event. The caxirola, based on the African caxixi, was invented by Brazilian musician Carlinhos Brown to be more subdued than the vuvuzela. To see if this was really the case, Talita Pozzer and Stephan Paul of the Federal University of Santa Maria in Brazil studied the acoustics of the instrument, finding that a single caxirola, at least, poses no threat to the user's ear designer brands for less.
Their work will be presented at the 166th meeting of the Acoustic Society of America, held Dec. 2-6, 2013, in San Francisco, Calif 明星百科.
In their analysis, the researchers asked 22 volunteers who had never seen the instrument to play it as they thought it should be played, finding that people tend to either shake it along its longer axis or its shorter axis. A recording device placed at the ear of each subject measured the sound of the caxirola Tai O Cable Car.
The researchers found that if shaken along the longer axis, the instrument produces twice the sound energy as when shaken along the shorter axis. But because volume depends logarithmically on the sound energy, the difference is only just noticeable to the ear. In both playing styles, the sound pressure levels were comparable to that of a normal conversation – and roughly 45 decibels lower than that of the vuvuzela, corresponding to 1/30,000th times the sound energy. In other words, you would need 30,000 caxirolas to produce the same sound pressure level as a single vuvuzela.
The researchers also captured the acoustic signature of the caxirola played in both styles, measuring how the frequency and intensity of the sound varies over time. The signature was similar in both cases.
The next step, Paul said, is to measure the caxirola's sound power levels, which, unlike sound pressure levels, are independent of distance and the instrument's surroundings. The researchers can then input those measurements into a computer model of soccer stadiums, simulating exactly what kind of noise thousands of caxirolas would make, showing whether or not it would be harmful.
Since its introduction last year, the caxirola has already been mired in controversy. After disgruntled fans hurled the instrument on the field during a match in April, officials banned the instrument for the Confederations Cup last summer. Whether the caxirola will be distributed during the 2014 World Cup has yet to be determined, Paul said.
Perhaps it's not the caxirola's acoustics that's a cause for concern – but its aerodynamics
