Problem: If someone asks you, "What do you usually do with your QQ?'' You may say, "I just chat ." Niu Lianzhong teaches PE in a middle school and he sets up a QQ group. However, his purpose is not to chat or show himself. He doesn't want to do anything for fun, either. He just wants more people to know the QQ group. He hopes to help others and now he saves more than 400 people's lives. We all know there are four blood types-A, B, AB, and O. But in fact, a few people's blood types are very special . Niu is just one of them. Since he sets up his QQ group, more than 100 special-blooded people in China join in it. Now, when a patient or a hospital needs some special blood, they just call Niu for help. And Niu contacts his members of the QQ group quickly. Till now, he has donated his blood for about 20 times. Niu hopes that more people will join his group to help others.

Q: (InStyle.com) -- Style, beauty and a certain je ne sais quoi is in the genes for these ultra-glamorous mother/daughter duos.

Goldie Hawn and Kate Hudson

Goldie made a name for herself starring in romantic comedies that highlighted her sense of humor as well as her acting chops.

If that sounds familiar, it's because it's the same exact career trajectory her gorgeous daughter Kate Hudson chose to take. Along with loads of talent, these two also share a love for a laid-back California-girl style.

Blythe Danner and Gwyneth Paltrow

Acclaimed actress Blythe Danner passed along regal good looks and a whole lot of talent to her Oscar-winning daughter. The consummately chic Gwyneth Paltrow is well on her way to becoming a lifestyle guru for her generation with her tip-filled e-mail newsletter GOOP.

And, although her sexy ultra-minis may seem far afield from her mother's sophisticated suits, she draws inspiration from Blythe: "In her, I see the incredible beauty of someone who has lived a life."

Demi Moore and Rumer Willis

Rumer Willis scored more than just Demi Moore's raven locks and high cheekbones -- the up-and-coming actress has an all-access pass to her mother's killer wardrobe. Despite this shared resource, Rumer has developed her own enviable edgy-glam style, a true departure from mom's ever-ladylike looks.

Madonna and Lourdes Leon

With one of the world's most famous women as your mom, Lourdes Leon has some pretty tall -- and expensive -- shoes to fill.

But the teenager, who is helping her mum design a line of clothing for Macy's, is out to prove she's a creative force to be reckoned with, too.

Problem: Steam engines are external combustion engines, where the working fluid is separate from the combustion products. Non-combustion heat sources such as solar power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In the cycle, water is heated and transforms into steam within a boiler operating at a high pressure. When expanded through pistons or turbines, mechanical work is done. The reduced-pressure steam is then condensed and pumped back into the boiler.

The first commercially successful true engine, in that it could generate power and transmit it to a machine, was the atmospheric engine, invented by Thomas Newcomen around 1712. It was an improvement over Savery's steam pump, using a piston as proposed by Papin. Newcomen's engine was relatively inefficient, and in most cases was used for pumping water. It worked by creating a partial vacuum by condensing steam under a piston within a cylinder. It was employed for draining mine workings at depths hitherto impossible, and also for providing a reusable water supply for driving waterwheels at factories sited away from a suitable "head". Water that had passed over the wheel was pumped back up into a storage reservoir above the wheel.
