NATHAN Chen became the first man in history to land five quadruple jumps in a single performance at an ISU championship event to win the Four Continents in Pyeonchang, South Korea, yesterday.
The American champion, 17, set international-best scores across the board Nike Vapormax Black
, finishing with 307.46 points and holding off a challenge by Olympic champion Yuzuru Hanyu, who was first in yesterday’s free skate.
“I tried five quads today and I landed three of the five solidly,” Chen said. “The other two were a little shaky so that’s something I need to improve on for the worlds.”
Chen opened his routine with a quadruple lutz-triple toeloop combination at the Gangneung Ice Arena and followed that with four more quadruple jumps in a free skate that received 204.34 points. After his first jump, he added a quad flip, quad toe, quad toe-double toe and a quad salchow.
“This feels great Nike Vapormax Flyknit
,” said Chen. “This is the first championship event that I’ve won. I had a good lead coming out of the short program, which really benefited me in the long program.”
Hanyu, third after the short program, was second overall with 303.71 points. Shoma Uno, also of Japan, was third with 288.85.
LOS ANGELES Nike Vapormax
, March 19 (Xinhua) -- Compared to using conventional fuels, using biofuel blending jet engines can reduces particle number and mass emissions in their exhaust trails by as much as 50 to 70 percent, a new study from U.S. space agency NASA found.
Worldwide, flights produced 781 million tonnes of CO2 in 2015, according to the Air Transport Action Group (ATAG).
The cooperative international research, published in the journal Nature Nike Air Vapormax Flyknit Navy
, was led by NASA and involving agencies from Germany and Canada.
The study shows that aviation-related aerosol emissions contribute to the formation of contrail cirrus clouds that can alter upper tropospheric radiation and water budgets, and therefore climate.
Data was gathered during flight tests in 2013 and 2014 near NASA's Armstrong Flight Research Center in Edwards, California, looking at the impact of alternative fuels on the performance of engines, emissions, and aircraft-generated contrails seen at altitudes that commercial airliners fly at.
The test series were part of the Alternative Fuel Effects on Contrails and Cruise Emissions Study (ACCESS).
NASA described the contrails as being produced by hot aircraft engine exhaust mixing with the cold air that is typical at cruise altitudes several miles above Earth's surface Nike Air Vapormax Navy
, and are composed primarily of water in the form of ice crystals.
"Soot emissions also are a major driver of contrail properties and their formation," Bruce Anderson, ACCESS project scientist at NASA's Langley Research Center in Hampton, Virginia, said in a statement.
"As a result, the observed particle reductions we've measured during ACCESS should directly translate into reduced ice crystal concentrations in contrails Nike Air Vapormax Flyknit Gold
, which in turn should help minimize their impact on Earth' s environment."
The benefits come not just from reducing carbon emitted directly into the atmosphere but by also cutting down the chance of contrails forming, which can have an even bigger impact on the Earth's atmosphere.
The results from research aircraft that sampled the exhaust of engines onboard a NASA DC-8 aircraft as they burned conventional Jet A fuel and a 50:50 (by volume) blend of Jet A fuel and a biofuel derived from Camelina oil.
"This was the first time we have quantified the amount of soot particles emitted by jet engines while burning a 50-50 blend of biofuel in flight," said Rich Moore, lead author of the Nature report.
Researchers plan on continuing these studies to understand and demonstrate the potential benefits of replacing current fuels in aircraft with biofuels. It's NASA's goal to demonstrate biofuels on their proposed supersonic X-plane, according to the agency.

Zou Shiming waited until his 30s to begin his professional boxing career Nike Air Vapormax Gold
, and he has been in a hurry ever since.
In just his seventh pro fight, China's double Olympic gold medalist will attempt to claim the IBF flyweight title belt this weekend.
Although Zou is an underdog in many boxing observers' minds when he meets Thailand's Amnat Ruenroeng on another big-money card in Macau, Zou and his promoters are eager to justify his enormous popularity with a championship.
Zou is still learning to fight like a professional under trainer Freddie Roach, who has attempted to rebuild Zou's slick amateur fighting style into a durable pro skill set. But with his 34th birthday looming this month, Zou didn't want to wait any longer to test himself against the best.
"I am very calm, not nervous Nike Air Vapormax Flyknit Triple White
," Zou said through a translator in Los Angeles recently. "I have been prepared for this moment for a long time. I am focused on myself, on executing Freddie's game plan. I felt a lot more pressure when I was in the Olympics. This time, the pressure is on Ruenroeng."
Zou's success has been the main reason for the growing popularity of boxing in China. His fight at the Cotai Arena in the opulent Venetian Macau will be available to more than 1 billion potential viewers in a nation where the sport was banned until the 1980s.
Yet Zou (6-0, 1 KO) realizes he is in for easily the most difficult test of his short pro career, which has been meticulously curated by promoter Top Rank to keep its prize Chinese fighter o.
