SAN FRANCISCO Cheap 903827-700 Men's Nike Air Max Plus Metallic Gold , Oct. 5 (Xinhua) -- Researchers at Stanford University have tested a bike helmet that comes in a soft pocket worn around the neck and pops up, like an air bag, around a person's head when it senses a potential collision.

Traditional "foam bike helmets can and have been proven to reduce the likelihood of skull fracture and other, more severe brain injury," said David Camarillo, an assistant professor of bioengineering at Stanford. "But Cheap en's Nike Air Max Plus Sunset Black Blue , I think many falsely believe that a bike helmet is there to protect against a concussion. That's not true."

Given that bicycling is the leading cause of sports- and activity-related concussion and brain injury in the United States, Camarillo's lab, which works on understanding and preventing concussion, decided to test a new type of helmet that is originally designed to address the fact that people do not like to wear helmets for aesthetic reasons and is starting to be available in some European countries.

"We conducted drop tests, which are typical (U.S.) federal tests to assess bicycle helmets, and we found that air bag helmets Cheap Nike Air VaporMax Mens , with the right initial pressure, can reduce head accelerations five to six times compared to a traditional bicycle helmet," Mehmet Kurt, a postdoctoral scholar in the Camarillo Lab, said in a Stanford news release.

Results of the test were published in the recent edition of Annals of Biomedical Engineering.

The drop test consisted of putting the helmets on a dummy head containing accelerometers and dropping it, neck-side up Cheap Nike Air VaporMax Womens , from various heights onto a metal platform.

The head form was tilted at two different angles, simulating hits to the crown and the side of the head.

Researchers dropped the helmets from as low as 0.8 meters to as high as two meters and measured the linear acceleration of the helmet as it struck the ground.

"As our paper suggests, although air bag helmets have the potential to reduce the acceleration levels that you experience during a bicycle accident, it also suggests that the initial pressure that your air bag helmet has is very critical in reducing these acceleration levels," Kurt said.

Camarillo said the large size of the air bag helmet compared to foam bike helmets is the likely source of its success. Being larger, it can also be softer Cheap Nike Air VaporMax 97 , allowing for a more cushioned fall.

However, this cushioning also has a potential downside. In the testing, the air bag helmet was pre-inflated and the researchers maximized the pressure of the air inside the helmet before each drop in order to get these results.

Without the maximum amount of air, the air bag helmet could bottom out, causing the head to hit the ground with much more force than if it were wearing a traditional foam helmet.

In current versions of the air bag helmet, a chemical process triggers expansion Cheap Nike Air VaporMax 2.0 , which doesn't seem to guarantee maximum air pressure.

Online retailer Lazada Group said it will sell select items from Alibaba Group Holding's Taobao marketplace in three more countries in Southeast Asia, expanding the partnership between the two e-commerce companies.

Taobao Collection will be offered in Indonesia, the Philippines and Thailand in the next few weeks through Lazada's platform, it said in a statement on Monday.

Lazada began selling Taobao products in Singapore and Malaysia earlier this year.

In June, Alibaba invested an additional $1 billion in Lazada to boost its stake to 83 percent.

The products are chosen to appeal to local tastes in each country and will be offered in the local languages on the Lazada sites, the company said.

BERLIN Cheap Nike Air VaporMax CS , Sept. 25 (Xinhua) -- With all votes counted, official results on early Monday confirmed that Germany's far-right Alternative fuer Deutschland (AfD) was elected in the federal parliament for the first time.

The anti-immigration populist party netted 12.6 percent of votes in Sunday's federal election, pinning itself as the third strongest party in the Bundestag, or German federal parliament, official results suggested.

It is also the first far-right populist party in the Bundestag since WWII.

Official results also showed AfD has won the most votes in the German eastern state of Saxony, by gaining 27 percent of votes Cheap Off-White Nike Air VaporMax , just slightly ahead of Chancellor Angela Merkel's Christian Democratic Union (CDU).

The CDU and their Bavarian-based Christian Social Union (CSU) allies secured its leading position in the Bundestag with 33 percent of the votes, 8.5 percentage points less than that of the 2013 and the worst performance since 1949.

The shrunken yet still commanding margin of the CDUCSU conservative alliance is set to herald a fourth term for Merkel as Chancellor, with the support of other parties.

The Union's major rival Social Democratic Party (SPD) led by Martin Schulz tumbled to 20.5 percent, while the Green and Left parties won about 8.9 percent and 9.2 percent, respectively.

The pro-business Free Democratic Party (FDP) enjoyed a remarkable 10.7 percent of votes and was re-elected into the Bundestag after its failure in 2013.
