ATHENS [url=http://www.teamseahawksjerseys.com/frank-clark-jersey/]Seahawks Frank Clark Jersey[/url] , March 8 (Xinhua) -- Hooligan violence in Greece persisted this weekend as the Super League football championship resumed behind closed doors amidst a fresh campaign to curb clashes between fans.
Two weeks ago the Sports Ministry suspended the games for a week following the violent scuffles between fans during two matches in the third time in six months.
This weekend the Super League games restarted behind closed doors as the ministry in cooperation with football associations examines measures to address the problem.
Shut out of stadiums hooligans clashed this time outside the offices of a fan club in the city of Thessaloniki in northern Greece.
At least one person was seriously injured during the clashes between fans of PAOK and rivals who supported Aris club, local police said.
Among the measures examined at the moment was the shutdown of fan clubs.
In autumn a football fan died in similar clashes during a third division game on the island of Crete. The second time the championship was suspended after the injury of a referee official in an assault.
CANBERRA, Nov. 10 (Xinhua) -- A common species of Australian pigeon uses the sound of its feathers to warn of impending danger, a local study has found.
Researchers from the Australian National University (ANU) found that rather than using vocals [url=http://www.teamseahawksjerseys.com/rees-odhiambo-jersey/]Seahawks Rees Odhiambo Jersey[/url] , the crested pigeon uses a high-pitched sound produced by its main flight feathers to warn fellow pigeons of predators.
As the pigeon flaps faster to escape danger, the tempo of the alarm signal automatically increases.
Trevor Murray, an animal communication expert from ANU, said on Friday that the team is able to prove that other crested pigeons flee when they hear the warning [url=http://www.teamseahawksjerseys.com/jarran-reed-jersey/]Seahawks Jarran Reed Jersey[/url] , proving it is used specifically as an alarm rather than a by-product of flight.
"Crested pigeons signal danger with noisy wings, not voices," Murray said in an ANU media release.
"It shows that birds really can use their feathers as 'musical instruments' to communicate with others."
In order to prove that the pigeon's whistling feather was an alarm system, researchers used high-speed video and conducted feather-removal studies.
They found that the bird's eighth primary wing feather was responsible for the high-pitched notes with each downstroke.
It was also discovered that the ninth feather produces a low-pitched sound that it was not involved in the alarm.
Researchers played flight sounds of crested pigeons with and without their eighth feather to a flock of other pigeons.
"We show that the crested pigeon produces an acoustic alarm signal with its wings and that it is an intrinsically reliable signal of danger [url=http://www.teamseahawksjerseys.com/germain-ifedi-jersey/]Seahawks Germain Ifedi Jersey[/url] ," Murray said.
"The alarm signal is intrinsically reliable because pigeons flap faster to escape predators, and this fast flapping automatically produces the high-tempo alarm signal."
HANGZHOU, Jan. 17 (Xinhua) -- Alibaba plans to pay two elderly employees an annual salary between 350,000 yuan (54 [url=http://www.teamseahawksjerseys.com/tedric-thompson-jersey/]Seahawks Tedric Thompson Jersey[/url] ,000 U.S. dollars) and 400,000 to work for its e-commerce platform Taobao.
According to a job ad released on its official website Tuesday, Taobao wants to hire two "product experiencers" over the age of 60 to help the company collect user experiences on its new customized shopping platform.
Alibaba said applicants should have an easy rapport with children, have stable groups of friends and have good communication skills.
Apart from that [url=http://www.teamseahawksjerseys.com/amara-darboh-jersey/]Seahawks Amara Darboh Jersey[/url] , they must have at least one year of online shopping experience. Being a "group influencer," such as the leader of a square dancing team or a member of a neighborhood committee, is also a plus, according to the company.
Alibaba said the company has seen a massive response and is now short-listing candidates for interviews.
Analysts said Alibaba's move reflects the growing role of the elderly in China's burgeoning online shopping market.
Alibaba's Tmall online marketplace has 30 million registered elderly users [url=http://www.teamseahawksjerseys.com/nazair-jones-jersey/]Seahawks Nazair Jones Jersey[/url] , who prefer electronic products and home appliances over other product categories.
According to a survey of nearly 10,000 people aged 50 and older, about 90 percent said they were willing to learn new things, such as online shopping and how to use mobile payment.
At the end of 2016 [url=http://www.teamseahawksjerseys.com/delano-hill-jersey/]Seahawks Delano Hill Jersey[/url] , China had 230 million people aged 60 and older.
If you are as busy as most people you are always looking for ways to feed
your family in convenient, fast, yet not-too-expensive ways. Try the following
suggestions: 1. Cooking several meals for the week at one time. It may take a
few hours of your time up front but will pay off in the long run when you come
home each evening and have a meal ready to eat in a short amount of time. Try
cooking a roast and using part of it as a main meal and then using some for
sandwiches, beef stroganoff or as part of a stir-fry. Fry several pounds of
hamburger and make a
casserole [url=http://www.teamseahawksjerseys.com/shaquill-griffin-jersey/]Seahawks
Shaquill Griffin Jersey[/url] , taco meat and chili to freeze for use later in
the week. 2. After you return home from the grocery store clean all the fruits
and vegetables you can. When it's time for a meal all you will have to do is
cook them or add them to a salad or soup. 3. Get ideas from the cooking shows on
T.V. There are great shows that show you how to make a healthy meal in a short
time. 4. Develop a revolving recipe file. If you get bogged down by the idea of
having to plan 30 meals a month the recipe file is for you. For more details
visit us at blueribbon-recipes. Let family members choose some of their
favorites and put the recipes in a monthly file. Flip to day five or fifteen and
there is the meal just waiting to be cooked. 5. Enlist the help of the members
of your family. As soon as the kids are old enough divide up the cooking
responsibilities. Let everyone take turns with specific tasks or the whole meal.
