Why airlines do not give umbrellas passengers?

There are many unanswered questions every day about the reason for not granting airline passenger air umbrellas to use them during the exposure to the air in the plane accident
Where some believe that wearing the parachute and landing of the aircraft could save anyone from the process of the crash or explode in the air
But that all civil aircraft operating on the passenger transport from one country to another or from one city to another
Flying at high altitudes meaning it once you open the door of the plane in the air, will create a decrease in oxygen to a fatal degree that this plane was traveling at less than 370 kilometers per hour
But if the speed is the biggest anyone who will jump out of the plane will crash and immediately turns to pieces because of the severity of Aldaft

Lancement «satellites» Internet fournit rapidement

Detection founder and CEO of the company «SpaceX» SpaceX American space technology, Elon Musk, the latest ideas related to the launch satellites into Earth orbit to create a network of contacts and will be described as the largest of its kind. He explained holder, during his remarks at an event for the Foundation «SpaceX» in the US city of Seattle, finally, to those that will be launched into space «satellite network will provide high-speed and low-cost Internet service to billions of users on the ground».

He added that «the network may provide Internet service to three billion people from non-existing users of the Internet, as will be solved the problem of poor Internet connection in some areas around the world, and will increase the current speed of the flow of data on the Internet».

He pointed out that the holder satellite network will be the largest global communications system, and will be launched into Earth orbit 750 miles above the ball termites, so low a distance of more than synchronous orbit, where most satellites orbiting the current connections.

It is expected that the satellite network that compete, at the theoretical level, submarine cables, which are still facing problems in connecting the Internet service to some areas around the world, is also expected to help low distance to the network to run most Web services without any problems, to limit the distance that Stqtaha signals electromagnetic between the satellite and the device for future reference.

In terms of the future potential of the network, Mask said: «may be the primary means of Internet use in large areas around the world, especially the speed with which will be characterized by comparison with cables, as the speed of light 40% faster in the vacuum of space than in fiber».

Bitter cold keeps fit

A recent study revealed that exposure to low temperatures may increase the protein levels of newly discovered plays a crucial role in the formation of brown fat, which is fat needed to generate energy in our bodies.

Researchers at the University of California found that prolonged exposure to cold air, pushes this protein, to help fat cells White deployed in our bodies, which deliberately to excess energy storage, to become like structure of fat cells in their ability to burn fat and energy.

"The Hei Sook Sul" professor at the University of California Perhaps Om, nutrition and toxicology, Knowing the proteins that regulate the structure of fat, is important to the role of these fats not only in the generation of heat, but to influence the metabolism and insulin resistance.

The «Seoul» that doubling the levels of this protein by prescription drugs, can have a profound impact in double lipids important infrastructure in the loss of excess weight, even in the case of eating the same amount of food and quality of full-fat.

Unlike white fat, which works on energy and fat storage, Fat infrastructure works to burn energy for the stability Tdfitna where gaining color structures of relatively high levels of «mitochondria» which is tantamount to a power plant in the cell in humans

Facebook 'Legacy Contact' Will Manage Your Account When You Die

It's hard to imagine the world still turning after you pass away. But the sun will continue to rise and set, the oceans will continue to ebb and flow, and Facebook will still be home to cat videos and politically fueled arguments.

But what about your social media profiles? Unless you've shared your passwords, your family or significant other will likely be locked out of your accounts.

Facebook has been grappling with this issue for a number of years; in 2009, it allowed people to turn the profiles of deceased users into memorial pages. But Facebook is now adding a new option that users can select prior to their death: a legacy contact.

Pick your "legacy contact" wisely: Be it a family member or friend, they'll be able to post announcements and messages on your memorialized timeline, respond to new friend requests, and update your profile picture and cover photo.

Facebook Legacy ContactIf you're really trusting, you can also give permission for them to download an archive of photos, updates, and profile information shared via your account.

Facebook also redesigned memorial profiles by adding the word "Remembering" above the deceased's name and will allow a legacy contact to pin a post to the top of their timeline.

Other settings, however, will remain as you left them. The legacy contact, according to Facebook, will not be able to log in as the deceased, or see their private messages.

On the other hand, if you'd rather your social media life die along with you, just put in a request for your Facebook account to be permanently deleted after death.

"Until now, when someone passed away, we offered a basic memorialized account which was viewable, but could not be managed by anyone," the Facebook team wrote in a blog post. "By talking to people who have experienced loss, we realized there is more we can do to support those who are grieving and those who want a say in what happens to their account after death."

Visit the Facebook settings page to choose a legacy contact. Tap Security, then Legacy Contact at the bottom of the page.

You can also send a message to your chosen contact: "Since you know me well and I trust you, I choose you. Please let me know if you want to talk about this."

The optional feature is rolling out slowly to U.S. residents first, before expanding to more countries.

Why exercise and diet changes may not be enough to treat obesity

To treat people who are obese, doctors need to move beyond simply telling their patients to eat less and exercise more, some researchers argue.

Instead, doctors should focus on the biological mechanisms that make it hard for obese people to lose weight, these researchers say.

When people diet, the body thinks that it's starving, so several biological mechanisms kick in to encourage people to eat more so that they gain the weight back, said Christopher Ochner, an assistant professor of pediatrics and psychiatry at the Icahn School of Medicine at Mount Sinai in New York. For example, the body slows down the rate at which it burns calories in order to conserve fat, and there are changes in brain signaling that make people more attracted to high-calorie foods, Ochner said.

These mechanisms originally evolved to help humans survive when food was scarce, but "the problem is that those same mechanisms kick in if somebody is 400 lbs. and trying to lose 40 lbs.," Ochner said.

This reasoning explains why about 80 to 95 percent of obese people who lose weight eventually regain it, Ochner said. "In people who have been obese for many years, he noted, "body weight seems to become biologically 'stamped in' and defended." [13 Kitchen Changes That Can Help You Lose Weight]
