Dancers perform during the closing ceremony of the 16th Asian Games in Guangzhou, China, Saturday, Nov. 27, 2010. APThe skies lit up with dazzling fireworks as an emotional China brought the curtains down on the biggest Asian Games in a riot of colour, foot-tapping music and a cultural extravaganza at the Haixinsha Island on the Pearl River in Guangzhou on Saturday.If the opening ceremony held at the same riverside venue on November 12th was high on technical wizardry, the closing was a heart-touching display of warmth by the people of this South China city whose infrastructure has improved remendously as a result of hosting the Games which saw India record their best-ever medal haul till date.Late charge helps IndiaNov 26 | India record its bestCLOSING EVENT: SEE PHOTOSHIGHLIGHTSAsiad closing: Vijender India’s flagbearerIndia finished sixth on the medal rostrum with a record 14 gold, 17 silver and 33 bronze for an overall tally of 64, eclipsing their earlier record of 57 medals in the 1982 Asian Games in Delhi.South Korea’s Ji Youngjun celebrates with his national flag after winning the men’s marathon at the 2010 16th Asian Games in Guangzhou, China, Saturday, Nov. 27, 2010. APThe closing ceremony was also used by the Games hosts to present cultural segments representing the different regions of the continent, including South Asia in which Indian singers Ravi Tripathi and Tanya Gupta enthralled the capacity crowd.Hosts China were unstoppable in their relentless march to titles and at the end of the Games had an incredible harvest of 199 gold in an overall haul of over 400 medals, proving once again that they are in the top-most echelons of world sports.advertisementKorea finished way behind in second place while Japan were third that underlined the fact that the Asian Games, the second largest sports event after the Olympic Games, are still being overwhelmingly dominated by the far eastern nations of the continent.The prelude to the official part of the ceremony was punctuated by dance of Qiling (a legendary animal symbolizing good luck) to celebrate the success of the Games that was followed by an exhibition of acrobatics and dance.Performers staged “Dragon drunk on the Pearl River”, “Painting of Toy figuring in Emotion” and “Wind of the Yao Ethnic Group” dances while flashbacks of the Asian Games actions were shown on sail-shaped screens before the Chinese President Hu Jintao and Olympic Council of Asia Chief Sheikh Ahmad Al-Fahad Al-Sabah entered the arena to the strains of the Chinese Military Band.With nine plumes of red smoke rising up from the Guangzhou Tower, an athlete jumped out of the screen while the eight sail-shaped screens showed some memorable moments of the Games competitions.The plumes changed shape one by one and the fireworks started on the Guangzhou Tower to symbolize the success of the Games and the happiness it produced. The five-starred red flag of China was unfurled and the hosts? national anthem was played by the Military band.A small cultural segment was then presented with fishing lights shaped as starlight and the crescent moon used as major props to create a dream-like atmosphere of changing colours and flowing figures, the images giving the crowd an impression of fairy tales and scenes of fishing.The face of a smiling child appeared which turned into a beautiful girl from this city of ten million who frolics in the night sky amidst the stars.When she extended her hand all the stars and moon fell into her grasp and she, with a laugh, threw the stars and moon to the Games Torch Tower in the centre of the square.As they fell to the ground, hundreds of children appeared like magic and scattered in all directions to form the Asian Games emblem.A ship resembling a crescent moon with singing children on board gently set sail on the front waterway and hundreds of chorus singers with stars in their hands in four groups entered from two sides.A child singer picked up a Lingnan-style fishing lantern made of bamboo splits ecclosed by paper from the water.Almost immediately several fishing lights in different colours appeared on the scene winding in groups or strings through the site as the children with star lights in their hands flashed those lights to give an impression of a sea of lights.This was followed by the representation of India and the Ganga with the holy river appearing on the sail-shaped screen and running towards the famous temples of India while the screen also showed images of the Taj Mahal and modern architecture.advertisementSeveral dancers led by Cai Yushan and Xi Chuhang performed to the singing of Tripathi and Gupta and there were also motorcycle stunts done in front of the Games Torch Tower.One hundred men performers with Indian flower wreaths in their hands danced in two groups behind the bikes and formed two crescent moons on both sides of the Torch Tower while over 1000 chorus members holding multi-coloured Indian light-reflecting towels danced in harmony.When the two Indian singers came to the front, male dancers ran along the two sides of the Torch Tower to form a triangular pattern and danced with gusto while around 200 women dancers ran out, divided themselves in two groups and performed various Indian dance forms.The men and women dancers came together to form a semi circle they danced together to the song in typical Bollywood style.The other regions of the continent were also given their prominence in the cultural milieu before flashbacks of the Asian Games competitions and athletes being awarded their medals were shown along with emotional scenes, symbolizing the excitement and harmony that was visible during the Games.The cultural show ended with all the participants coming on to the stage forming different patterns while singing and dancing with abandon to bring an end to the cultural part and the commencement of the formal part of the ceremony with the arrival of the athletes.The Indian flag was carried by gold medal winning star boxer Vijender Singh with his left hand in a cast following the thumb injury he sustained during last night’s final against two-time world champion Atoev Abbos of Uzbekistan.OCA President Sheikh Al-Sabah, accompanied by the president of the Chinese Olympic Committee, Liu Peng, executive president of the Games organizing committee Huang Huahua, and the mayor of Guangzhou Wan Qingliang, delivered the keynote address and declared the 16th Asiad closed.The OCA flag was then lowered and the OCA anthem played before the national flag of Korea, the next Games hosts at Incheon in 2014 was raised, in the presence of the vice president of the Korean Olympic Committee and the chief of the Incheon Games organizing committee.Guangzhou mayor Qingliang handed over the Asian Games torch to the OCA chief who, in turn, handed them over to the mayor of Incheon.Later the flag of the first Games held in Delhi in 1951 and the OCA flag were handed over to the Korean representatives by Huahua and Peng.The Koreans presented a short segment to the accompaniment of percussion instruments and taekwondo, the country’s martial arts, which is also part of the Games programme and “Welcome to Incheon” and “See you at Incheon in 2014” were flashed on the screen.The Games flame was extinguished before the fireworks lit up the night sky to signal the end of the closing ceremony.MORE MEDALS FOR CHINAEarlier, just five gold medals were on Saturday presented at the Asian Games, providing a rather slow-paced denouement for an event the Olympic Council of Asia president referred to as “one of the best ever.”advertisementZhou Chunxiu won the women’s marathon, giving China its 198th gold medal of the games, one shy of its eventual total. Myanmar took its first two – in the men’s and women’s doubles finals in sepaktakraw, and OCA chief Sheikh Ahmad Al-Fahad Al-Sabah told a closing news conference that even a military conflict on the Korean peninsula last Tuesday during the games could not damage the event’s image.North and South Korean “athletes stood shoulder-to-shoulder to compete even though there had been some problems in their countries,” Al-Sabah said.After 48 gold medals were presented Friday in a hectic penultimate day, Zhou won the first of the last-day medals when she finished the marathon in 2 hours, 25 minutes, about 90 seconds ahead of her Chinese compatriot Zhui Xiaolon. Kim Kum Ok of North Korea won the bronze.Ji Young-jun of South Korea won gold in the men’s marathon, finishing in 2:11.11, with Japan’s Yukihiro Kitaoka second. That ended China’s chances of capturing 200 gold medals at Guangzhou.Myanmar, formerly known as Burma, won its previous gold in sepak takraw in 1998 in the women’s regu division of the acrobatic volleyball-like sport in which competitors use just about everything but their hands to get a rattan ball over the net. Myanmar’s men beat South Korea 2-0 and its women defeated China 2-1.”We have a new flag and we are proud to have won the gold medal under it,” said Myanmar coach Kyaw Zin Moe.China won the first gold of the games on Nov. 13 when Yuan Xiaochao finished first in wushu martial arts event, and took the last on Saturday. The Chinese women’s volleyball team came back from two sets down to beat South Korea 21-25, 22-25, 25-10, 25-17, 16-14, leaving its final gold medal count for the games at 199.The closing ceremony, featuring a performance by the military band of the Chinese People’s Liberation Army and the official handover from Guangzhou to Incheon, was scheduled for later Saturday.With inputs from PTI/AP
Nearly a month removed from his withdrawal from the Players Championship, Tiger Woods and all the drama that surrounds him return to competition today at the Memorial Tournament.Maintaining the No. 1 spot atop the World Golf Rankings for the last five years, there is never a lack of public intrigue surrounding Tiger Woods.With his recent neck injury and issues with his personal life, however, the 14-time major champion has drawn even more headlines than usual in the last six months. It has been a rocky road for Woods dating back to his Nov. 27 car accident. From the admittance of his adulterous ways to his pending divorce, Tiger’s life off the course was a mess.Professionally, things started looking up for Woods following a strong showing at Augusta National in which he finished tied for fourth. Tiger’s moment of light was short lived. After missing the cut at the Quail Hollow Championship, Woods couldn’t even finish the following week at the Players Championship, withdrawing on the seventh hole during Sunday’s final round due to a sore neck. Resting and rehabbing his neck since the Players, Tiger is back at the Memorial trying to right the ship once again. “I think that life is moving forward … the last six months have been pretty tough, and I’m now starting to get into golf and starting to play golf again,” he said.Being the defending Memorial champion and having the most all-time wins of any player at Jack Nicklaus’ tournament, this week seems as good as any for Tiger to get back at it.“I’ve always had good memories here,” Woods said. “It’s nice to come back to a golf course when obviously I haven’t played a whole lot this year, but it’s nice to come back to a venue where I have played well.”While Muirfield has treated him well, it remains to be seen whether Woods’ game is back to the form that golf fans are accustomed to, especially considering his recent break-up with longtime swing coach Hank Haney.“I’ve hit the ball much better,” Woods said. “It’s just like anything, though. It’s great to hit it at home, but I need to bring it out here.” For the time being, Tiger is using video to analyze his own swing and says as of now he has no plans for hiring a new coach.Even with the recent neck injury and mediocre play of late, Tiger’s competitors know not to count him out this week.“Anytime Tiger is in the field, you know you are going to have to be on top of your game to win,” said 2009 U.S. Open champion Lucas Glover.For many, after playing just nine competitive rounds all season, simply making the cut would be a victory in and of itself, but for Tiger Woods nothing is out of the realm of possibilities. “I never like to assume what he can and can’t do because he proves us all wrong all the time,” said Aussie golfer Adam Scott. Woods will take to the course at 12:44 p.m. today to begin his first round of play alongside Steve Stricker and Jason Bohn.

Thai divers gather before they enter to the Tham Luang cave, where 12 boys and their soccer coach are trapped, in the northern province of Chiang Rai, Thailand on 6 July 2018. Photo: ReutersMore than 100 chimneys are being drilled into the mountainside in a frantic bid to reach a Thai youth football team trapped in a cave complex below, the head of the rescue mission said Saturday.The unprecedented rescue effort is attempting to establish new ways to extract the boys from above, if the underground chambers flood and it is deemed too risky to evacuate the team by diving out through the submerged passageways.”Some (of the chimneys) are as deep as 400 metres… but they still cannot find their location yet,” Narongsak Osottanakorn told reporters, adding the mission lacked the technology “to pinpoint where they are staying”.”We estimate that (they) are 600 metres down, but we don’t know the (exact) target,” he said.On the question of dipping oxygen levels in the cave, he said rescuers had managed to establish a line to pump in fresh air and had also withdrawn non-essential workers from chamber three — where the rescue base is — to preserve levels inside the cave.The “Wild Boar” team have been trapped inside the Tham Luang cave complex for two weeks.
TulipA lawmaker has postponed giving birth in order to vote on Britain’s divorce deal with the EU on Tuesday.Tulip Siddiq, 36, was due to have a Caesarian section on the big day, but medics have agreed to delay the operation until Thursday so that she can vote on the withdrawal agreement struck between London and Brussels.The opposition Labour MP plans to be pushed through the voting lobby in parliament in a wheelchair.”If my son enters the world even one day later than the doctors advised, but it’s a world with a better chance of a strong relationship between Britain and Europe, then that’s worth fighting for,” she told the London Evening Standard newspaper.A source in Prime Minister Theresa May’s Conservative party said it had offered to “pair” Siddiq, meaning a rival MP agreed not to vote to ensure her absence did not affect the outcome.But Siddiq said she did not trust this informal system after the Conservatives broke a pair for a new mother MP last year.Labour colleagues asked John Bercow, the speaker of the lower House of Commons, if Siddiq could have a proxy vote, but he said this was not in his power as such a voting system has not been implemented.Bercow said he would like the procedure known as “nodding through” — where an MP who is on the parliamentary estate but physically unable to cast their ballot has their vote counted — extended to Siddiq’s hospital bed in north London.The new baby boy will be a great-grandson of the founding father of Bangladesh.Siddiq is the grand-daughter of Sheikh Mujibur Rahman, the first president of Bangladesh.Her aunt is Sheikh Hasina, who was sworn in as Bangladesh’s prime minister for a record fourth term last week after a crushing election victory marred by deadly violence and claims of widespread rigging.
Submitted to the AFRO by Dr. Kaye Wise WhiteheadAt any given moment, there are about a half a million stories that need to be told about the reality of growing up and trying to grow old in Baltimore City. Stories about racial and economic inequality; about predatory policing and structural racism; about health disparities and food apartheid; about some of the people who died, like Freddie Grey and Tyrone West, Taylor Hayes and Wadell Tate; and, about all of the people who are trying to live. In the book of Acts, the apostle Paul tells his fellow shipmates that an angel told him that the ship was going to crash and in order for them to survive, they would need to hang onto the broken pieces and make their way to shore. This is what it feels like trying to grow up and grow old in some neighborhoods in our city—you do everything you can to hang onto the broken pieces and try like hell to make it to the shore.Dr. Karsonya Wise Whitehead (Courtesy Photo)Life in Baltimore City is complicated. It is challenging and hard. It is racially segregated and economically divided. It is a tale of two cities—one mostly White and the other mostly Black, separate and unequal. I believe that in order to understand the deep sense of helplessness, hopelessness, and malaise that hangs like a cloud over certain parts of our city, you must intentionally spend some time in both Baltimores. You have to visit the schools, the corner stores, and the churches. You have to catch the buses and walk the streets. You have to try and see what it feels like to hang onto the broken pieces and what it feels like when you do not have to do this. This is what I have been doing for the past five months as I have been conducting my unofficial ethnographic study of Baltimore’s hypersegregated Black neighborhoods. I have been trying to understand what life is like within the Black Butterfly, trying to find some answers to the questions that I have been wrestling with since 2015 when a Harvard University study concluded that out of the nation’s 100 largest jurisdictions, children born in poverty in Baltimore City have the worst chances of ever escaping it.As much as possible, I spend my time talking to young people, asking them questions and trying to listen to them. I want to see the world from their perspective. I want to hear their stories and in some small way, help to shoulder their pain. Part of the reason why I do this is because of Jason, a ninth grade student from Frederick Douglass High School. I met him in the hallway last year when I hosted a teach-in at his school. I asked him (like I asked all of the students that day) what his plans were for his life and what did he want to be when he grew up. At first, he did not respond. He turned and leaned up against the locker. He sighed and checked his phone. I just stood there, quiet, hoping that he would answer me. “My father is dead.” he said, “My brother is dead. I had two cousins, they got shot. My uncles are locked up. What do I want to be when I grow up? Nothing. I’m from Baltimore, I’m already dead.”I did not say anything. He looked at me and then turned and walked away. I wanted to go after him. I wanted to talk to him and tell him that he was going to be ok. I wanted to ensure him that he could make it, that I was going to help him, and that together we could change his future. I wanted to do and say all of this, but I did not. I felt overwhelmed. Standing in the hallway, it was hard to breathe and hard to imagine a different way forward. His life, according to the data, was being shaped by racially segregated neighborhoods, poverty, poor schools, subpar housing, drugs, gangs and a history of racism; his response showed that he had been listening, he had been watching, and he is no longer waiting for someone or something to come along and save him. He did not believe that he could be saved and, on that day, standing in the hallway, listening to his story, I failed to tell him that he could. I will not fail again.Karsonya Wise Whitehead is the #blackmommyactivist and an associate professor of communication and African and African American studies at Loyola University Maryland.

By Sean Yoes, AFRO Baltimore Editor, email@example.comAugust 2017, Erricka Bridgeford, Letrice Gant, Ogun Gordy, Darnyle Wharton, Jakia Jason and Michelle Shellers, launched the first “Nobody Kill Anybody”Baltimore Ceasefire weekend.It was two short years after the Uprising of 2015, two dreadful years that saw the city easily eclipse the 300 murder mark, and we were in the midst of a third consecutive year of 300 homicides. By August 2017, the city and the Baltimore Police Department (BPD) had been slapped with an historic Consent Decree by the U.S. Department of Justice, in the aftermath of the homicide of Freddie Gray while in BPD custody. The garish quality of seemingly ubiquitous police corruption was headed towards an all-time high (The Gun Trace Task Force and the homicide of Det. Sean Suiter were still on the bleak horizon), and community confidence in the police was at an all-time low. The audacity of six Black people to come forward and command a cessation of murder in Baltimore, the most violent city in America seemed remarkable. Their request seemed implausible.Sean Yoes (Courtesy Photo)Yet, despite tremendous doubt, outright resistance and ridicule the Ceasefire crew pressed forward by faith. At the end of 72 hours, the Ceasefire movement mourned the deaths of Lamontrey Tynes and Donte Johnson on day two of the Ceasefire. However, there were no murders recorded for a total of 67 of the 72 (41 continous hours without a murder) hours at a time when the city was averaging a murder approximately every 19 hours.The eyes of the world were on Baltimore for that first Ceasefire and although we tragically lost the lives of two more young Black men, the majority of the city responded positively to the challenge.Thousands of Baltimoreans eschewed violence, murder and mayhem and celebrated life, at least for 72 glorious hours. The concept of Ceasefire had fired the imaginations of many. The three subsequent Ceasefire weekend after the first, the homicide numbers came down from two to one, to none, to none again.Now, two years after the first Ceasefire there is empirical evidence available as we head towards the August 2019 Ceasefire, which supports what many believe, the movement is working.In a study called, “Modeling the Effect of Baltimore Ceasefire,” published June 13, by Open Baltimore (a city agency), statistical data on shootings during the Ceasefire weekends indicate there have been 60 percent fewer shootings during the 72 hour period. “The effect of the Ceasefire is classically significant and suggest an approximate 60 percent reduction in shootings during ceasefire weekends,” according to the report.Further, the report indicates, “Without a ceasefire, we would expect about three or four people to get shot on the first day of the weekend, on average. But, this will be a Ceasefire weekend, so the model expects about two fewer shootings each day.” It is a stunning tangible result born out of an organic grassroots movement, an answer to mind-numbing violence (one of the group’s mantras is, “Don’t be numb.”)The statistical affirmation is welcomed by the leaders of Baltimore Ceasefire, although they knew in their spirits that their work was making a significant difference in the city.“Having this data confirms things we knew instinctively. With over 30 events every Ceasefire weekend, we knew Baltimoreans were shifting the atmosphere,” said Erricka Bridgeford, one of the Ceasefire co-founders, who has become the face of the movement globally.“When people told us they were going to keep their neighborhoods safe, we knew they were keeping their promises. But now, with proof that there are 60 percent fewer shootings during Ceasefire weekends, we can see that the more people know about a Ceasefire, the more peaceful Baltimore becomes,” she said.“This also proves that it is a good choice to believe in Baltimore.”Sean Yoes is the AFRO’s Baltimore editor and the author of Baltimore After Freddie Gray: Real Stories From One of America’s Great Imperiled Cities.
“Some people think that graphene, a form of carbon, is the material of the future,” Allen Goldman tells PhysOrg.com. “It’s of high scientific interest because of its unusual electronic properties.” Citation: A new type of spin valve that uses graphene (2007, July 9) retrieved 18 August 2019 from https://phys.org/news/2007-07-valve-graphene.html Goldman is a scientist at the University of Minnesota in Minneapolis. Working with Masaya Nishioka, also at the University of Minnesota, Goldman has found new insight into spin transport in graphene. Their findings are published in an article titled “Spin transport through multilayer graphene,” published in Applied Physics Letters.Goldman and Nishioka have created a spin valve, and also observed a magnetic field controlled resistance change of 0.39%. “It’s not a huge effect,” Goldman admits, “but it is a step.” He explains that this is not the first spin valve, but that it is the first that is “reasonably well characterized.” He continues: “This isn’t a huge breakthrough, but it is an incremental step in understanding graphene, and also a step in understanding whether this material has use in spin dependent electronics.”Spin dependent electronics, or “spintronics,” makes use of quantum spin states of electrons. Applications for spintronic devices, and spin valves in particular, are currently limited to mass-storage systems. However, the technology and science is so emergent, that further applications are possible. The spin valve, which is what Goldman and Nishioka’s work describes, makes use of magnetic thin films to control the resistive state of graphene: “We’re talking about a memory device that doesn’t have to be refreshed, and that is not volatile.”Because of its high electron mobility and low atomic number, graphene is of special interest in spintronics, and this is why Goldman and Nishioka chose to work with it. “The process seems really very simple,” says Goldman. He then writes via email to explain the process: “We take a substrate of silicon, which is doped and coated with silicon oxide. Then we place graphene flakes on the surface, and after selecting a suitable flake, fabricate a pair of cobalt electrodes to contact the flake. We can then switch the resistive state of the flake by controlling the relative orientations of the magnetizations of the electrodes.” But there are caveats. “Even though the set up is simple, it can be hard to make these devices,” Goldman says over the phone. “And even though we can make graphene, it is a difficult process, especially to make single-layer graphene, which is why use multilayer graphene.” He emphasizes again that the effect he and Nishioka observed was quite small.The goal, Goldman says, is to be able to master graphene to an extent that it would become possible to produce technologically useful devices. “Right now, we are at a point where we deal with little flakes. We need to work with films that are ordered over macroscopic distances,” he says.Goldman feels that there is potential in graphene. “I don’t really know if it is the material of the future,” he explains, “but this experiment brings us a step closer to understanding it better. If the problems with graphene can be solved, there is a very good chance that it could be very useful.”Copyright 2007 PhysOrg.com. All rights reserved.
