RIO DE JANEIRO， Aug. 15 (Xinhua) -- Eleftherios Petrounias claimed the men's rings gold here on Monday at the Rio Olympic Games.
The 25-year-old gymnast earned the highest score of 16.000 points in the first final of gymnastics on Monday after a strong performance with perfect landing.
Brazilian veteran Arthur Zanetti failed to defend his title， but brought home a silver in 15.766 points， followed by Denis Abliazin of Russia in 15.700 points.
"I am feeling amazing. I am super excited，" said Petrounias. "We worked a lot. We worked very much for this result. It came as I expected. I think we worked a lot in the details， to be stable. It is difficult to move， to hold all your positions a little bit more than normal. And if you have a good landing， like I had， that's how the (score of) 16 came."
2014 world champion Liu Yang of China finished fourth and his teammate You Hao ranked sixth in the final.
"My aim was to win a gold medal. So the result is disappointing，" said the 21-year-old Liu， who shed tears in the mixed zone.
"The only mistake happened on the dismount and that's because I didn't have any energy left，" he said.
JUBA Cheap Nike Air Max 90 Womens , July 7 (Xinhua) -- An international charity said Friday there is little to celebrate six years after South Sudan seceded from Sudan amid conflict and food crisis.
In a statement issued ahead of Independence Day on Sunday, Norwegian Refugee Council (NRC) said while independence brought hopes of peace and development six years ago, today's ongoing conflict has resulted in four million South Sudanese having to flee their homes.
"South Sudan's Independence Day is overshadowed by conflict and an unprecedented food crisis. With more people facing a severe food crisis every month, there is unfortunately little reason to celebrate Cheap Nike Air Max Womens ," NRC Country Director Rehana Zawar said in a statement issued in Juba.
Zawar said close to two million people have fled South Sudan, about half of them finding refuge in Uganda.
She said humanitarian agencies need free and secure access to communities in need to be able to deliver life-saving assistance effectively.
"The Norwegian Refugee Council urges all parties to the conflict to suspend hostilities, ensure protection of civilians, engage in meaningful dialogue Cheap Air Max Thea Womens , and work towards a lasting peace," Zawar added.
The charity said the number of refugees has more than doubled since renewed fighting broke out in the capital Juba in July 2016.
Another two million people have fled their communities seeking safety in swamps, remote areas and other parts of the country.
"South Sudan needs continued support for the humanitarian response more than ever before from international donors. The country will likely face a new famine on a greater scale in the coming year if relevant support is not provided," said Zawar.
She said aid agencies face increasing difficulty and risks to reach those in need Cheap Air Max 95 Womens , warning that without lasting peace the humanitarian emergency will continue and worsen.
The charity said fighting and displacement have prevented many farmers from planting crops and people from accessing markets, contributing to a desperate food emergency.
"Today six million people, roughly half of the population, do not have enough to eat. Although famine conditions recently subsided in Leer and Mayendit counties thanks to humanitarian assistance Cheap Air Max 90 Womens , the number of people on the brink of famine has increased to 1.7 million," it said.
NRC said cholera is spreading as more than 11,000 cases of cholera having been confirmed since South Sudan's worst cholera outbreak began about year ago, and 190 people have died to date.

SAN FRANCISCO, May 30 (Xinhua) -- U.S. scientists have recently developed a vital antibiotic to battle the world's most threatening superbugs.
The modified version of the antibiotic vancomycin appears to be 1,000-time more potent than the old one, according to a journal published by the Proceedings of the National Academy of Sciences in the United States.
Used only when treatment with other antibiotics fails Cheap Nike Air Max Thea Shoes , vancomycin is effective at fighting enterococci bacteria, which is found in hospitals and can cause dangerous wound and blood infections.
However, the increasing emergence of vancomycin-resistant enterococci has been worrying doctors worldwide.
The research team, from the Scripps Research Institute in California Cheap Nike Air Max 95 Shoes , makes strategic modification to the molecular structure of the old drug to destroy cell walls of the bacteria.
Three changes in particular seem to be crucial in "increasing the durability" of the drug, said Dale Boger, lead researcher from the Scripps Research Institute.
"Organisms just can't simultaneously work to find a way around three independent mechanisms of action," Dale Boger said.
The new drug has not been tested on animals and people yet.
