Barcelona to pay Dortmund this fee if they sell Ousmane Dembele – reports

first_img targets 2 Barcelona will reportedly have to pay Borussia Dortmund a further £26million if they sell Ousmane Dembele to Liverpool or Arsenal before the end of his contract.Dembele moved to the Nou Camp for a £96m fee but there are a number of performance-related add-ons which could see that fee rise to £131m. It is understood two payments of £4.5m have been made after the forward reached 25 appearances for Barca and the club made it to this season’s Champions League.And according to German newspaper De Welt, whatever remains of the additional fees will be due if Dembele leaves the Spanish giants before his contract finishes in 2022.The Reds and the Gunners have both been linked with moves for the 21-year-old, who has started 24 games in 15 months at Barca.The Daily Mirror reported Barca’s top brass have run out of patience with Dembele and want to offload him as soon as possible, slapping a £100m price tag on him. Dembele has started just 24 games in 15 months at Barca REVEALED Kevin De Bruyne ‘loves Man City and wants to keep winning’, reveals father Cavani ‘agrees’ to join new club and will complete free transfer next summer “There is no problem with Dembele.“It is a normal situation for a young player who has a lot of talent and has reached a very big club like Barca, with great players and teammates. He has never had this before and this generates a process of adaptation that has to happen.“He is very young and has never had to make the effort to adapt to this way of playing and we recognise that it is costing him. He also recognises it.“What we will do is work so that this adaptation is possible.” targets 2 Tony Cascarino backs Everton to sign two strikers for Carlo Ancelotti The biggest market value losers in 2019, including Bale and ex-Liverpool star moving on Man United joined by three other clubs in race for Erling Haaland Top nine Premier League free transfers of the decade IN DEMAND LIVING THE DREAM But when asked about a Dembele departure, Barca were keen to play down these suggestions.General manager Pep Segura said: “If you have information from the English press, ask the English press. If you have information about Liverpool, ask Liverpool.“As of today we have nothing for Dembele and we have no desire to change the structure of the template.“It is true that I had a meeting with Dembele’s agents. But I had three meetings with three other representatives. My job is to meet with representatives, they are common things.

SA to launch Aids plan for sex workers

first_img17 December 2013 South Africa’s plan to help protect sex workers against HIV and help them access treatment is a “flagship model” that should be followed by the rest of the world, Mark Dybul of the Global Fund to Fight Aids, Tuberculosis and Malaria told Africa’s biggest Aids conference held in Cape Town last week. Dybul lauded South Africa’s National Strategic Plan for HIV Prevention, Care and Treatment for Sex Workers as a comprehensive plan that “showed remarkable leadership and (was) a flagship of how we must respond not only on this continent but around the world”, Business Day reported. Dybul was speaking at the International Conference on AIDS and Sexually Transmitted Diseases in Africa on 10 December.Scaling up The plan was developed by South African National Aids Council (Sanac), the Sex Workers’ Education and Advocacy Taskforce (Sweat), Sisonke Sex Workers Movement and the departments of Social Development and Health, among others. It will form a part of the country’s National Strategic Plan for HIV and AIDS, TB and STIs 2012 – 2016. The plan involves a significant scaling up of a comprehensive HIV prevention package, improving services, reducing the discrimination against sex workers and mobilising resources, Business Day says. It aims to increase access to HIV treatment for the estimated 153 000 sex workers in South Africa, reduce the violence and human rights abuses perpetrated against them and to promote their well being. Fareed Abdullah, Sanca’s chief executive, writes in the foreword to the plan that addressing the health of sex workers is “crucial to our plans to combat the spread of HIV” in South Africa as they are most at risk of acquiring HIV and other sexually transmitted infections”. Dybul reportedly said it was “appalling” that sex workers were 12 times less likely to receive antiretroviral treatment than other people. He said their rights had to be respected and they had to be brought into the human family and given choices regarding what to do with their lives. The launch of the plan, which was due to take place at the conference on Tuesday last week, has been postponed until 2014 out of respect for the passing of Nelson Mandela, South Africa’s former president, who died on 5 December. The Global Fund to Fight AIDS, Tuberculosis and Malaria donated R3-billion in October to South Africa for its HIV/Aids programmes, an amount which will supplement prevention and referral services for two-and-a-half years. Further funding from the organisation will assist specific HIV health services for sex workers in the future, Sanca’s Rentia Agenbag told SAinfo. Business Day and SAinfo reporterlast_img read more

According to rankings from ESPN’s Jonathan Givony, six of the top seven prospects in this year’s draft stand 6-foot-10 or taller. (The one exception is Real Madrid’s Luca Doncic, a 6-foot-8 point guard.) If things play out according to ESPN’s latest mock draft, this could be the second-tallest collection of top-10 picks in any draft since the lottery era began in 1985: 2018 is looking like one of the tallest drafts everTallest average height for top 10 picks in an NBA draft, 1985-2018 YearAvg.

Seikaly6’11”D. Manning6’10” Headlined by Arizona 7-footer Deandre Ayton, this crop of big men is poised to have a profound effect on the league’s future. But therein lies a paradox: In the sport that prizes height like no other, the game itself is moving away from the archetype of the plodding big man. How each top prospect handles this seeming contradiction will go a long way toward determining what kind of pro career he’ll end up enjoying.The changing role of tall players in today’s pace-and-space NBA is complicated. As our ESPN colleague Kevin Pelton noted last week, bigs are actually more effective on a per-minute basis than ever, at least according to player-value metrics. Even though their share of leaguewide minutes has stayed relatively constant since the late 1980s, the share of NBA value over replacement player (VORP) accumulated by players 6-foot-10 or taller has been on the rise, hitting a modern high-water mark during the 2017-18 season, when bigs accounted for 39.5 percent of total value: Last season, 21 of the league’s 50 most valuable players by VORP stood 6-foot-10 or taller, another high for the league since the ABA merger in 1976. So in that sense, towering talents such as Anthony Davis, Nikola Jokic, Karl-Anthony Towns, Giannis Antetokounmpo and Ben Simmons are doing just fine in the modern NBA, thank you very much.But at the same time, it’s difficult to conclude that this is a true heyday for taller players when you consider how little difference any of them made during the playoffs.1Granted, NBA Finals MVP Kevin Durant is listed as 6-foot-9, but he is certainly taller than that. The percentage of total postseason minutes logged by players 6-foot-10 or taller has fallen from 29 percent in 2009 (the year 6-foot-11 Dwight Howard led the Orlando Magic to the NBA Finals) to 22 percent this year. At the same time, the share of playoff VORP belonging to big men has fallen from 34 percent to 26 percent. Only two players 6-foot-10 or taller — Kevin Love and JaVale McGee — played any significant minutes in the NBA Finals.2The series’ other players who stand 6-foot-10 or taller — Zaza Pachulia and Ante Zizic — were on the court for a grand total of 11 minutes over the series’ four games. In recent postseasons, the switch-heavy defensive schemes that top teams play have often made it a tactical liability to rely heavily on traditional big-man types, to say nothing of the negative effects of playing a nonshooter like most bigs have been throughout NBA history.Even among those who have survived these shifting conditions and remained relevant as NBA big men, the core responsibilities of the role have changed substantially over time. The floor-spacing element alone has not only put added pressure on bigs to develop greater range as shooters — 7-footers now take more than double the number of threes they did just five seasons ago, according to ESPN’s Stats & Information Group — but it also requires them to be able to move fluidly in larger areas of defensive space, as well as taking a more active role in ballhandling and passing duties.You can see these changes playing out statistically as today’s big men are diversifying their contributions. Relative to the league average, the typical player who stands 6-foot-10 or taller in the 2010s gets significantly more assists and steals than in previous decades; he also is a much more frequent and efficient scorer and rebounder, but he blocks fewer shots. These changes have been about survival, and several of this draft’s elite post prospects have things they’ll need to prove in order to avoid becoming the next Jahlil Okafor, who entered the NBA with one of the best low-post arsenals in decades but couldn’t move his feet well enough to justify consistent playing time (let alone the No. 3 overall pick).The physically gifted Ayton, who spent much of this past season at power forward, logged very low steal and block rates when compared with other recent top-level post prospects, leading some to question his defensive instincts. Marvin Bagley III, who played zone during his one year at Duke, struggled at times defending the pick and roll, a vital trait in a league where that play can be used every time down the floor. And while Texas’s Mohamed Bamba will enter the NBA with a shot-blocking reputation — he has a ridiculous 7-foot-10 wingspan and erased almost four shots a game in college — it remains to be seen whether he’ll be able to make an impact on defense when teams seek to pull him out with a stretch-big who doesn’t need to be tethered to the paint.If we learned anything during these NBA playoffs — between Houston finding ways to torch and neutralize likely defensive player of the year Rudy Gobert and Golden State making mincemeat out of Cleveland’s switch-everything defense in the NBA Finals — it’s that the best offenses generally have counterpunches against highly predictable defensive sets and players. With that in mind, it wouldn’t be a shock to see someone like Michigan State’s 6-foot-11 Jaren Jackson Jr. get drafted a few spots earlier than expected, given the defensive versatility he possesses.To be clear, it’s not just the big men who find themselves adapting to a changing game. Players at other positions will also come with a handful of question marks Thursday night for similar reasons. For all his game-changing offensive talents, Oklahoma guard Trae Young’s lack of size (he checks in at 6-foot-2 and just under 180 pounds, with only a 6-foot-4 wingspan) figures to give teams pause after an NBA postseason whose earlier rounds saw smaller guards targeted and exposed consistently on the defensive end. Among perimeter players — rookie and veteran alike — Young isn’t alone in that weakness.On a larger scale, though, the sheer number of elite big-men draft prospects leading the way this year may seem a bit odd, given how the league has seemingly downsized. But just keep in mind the necessary caveat: Big men are still alive and well in the NBA — as long as they can move their feet and possess more than one tangible skill. We’ll see how many of this year’s towering prospects can check off those boxes once they start playing against the pros. read more

Did Amitabh Bachchan sense trouble minutes before Vivek Oberoi tweeted about Aishwarya

first_imgAmitabh Bachchan and Vivek OberoiInstagram/Varinder ChawlaVivek Oberoi made headlines recently for his “insulting” tweet involving Aishwarya Rai Bachchan. But just some time before the controversial tweet, the actress’ father-in-law Amitabh Bachchan made an advisory tweet that goes perfectly for Vivek.Vivek tweeted out a meme that involved him, Salman Khan and Abhishek Bachchan with Aishwarya. The tweet did not go down well with majority of people, who trolled and lambasted the actor on social media.The concerned meme involved three pictures of Aishwarya – one with Salman, one with Vivek and the last one with Abhishek, referred to as “opinion polls”, “exit polls” and “results” respectively. This co-incidence came to notice of a lot of people, who were surprised to see the veteran actor making this tweet just some minutes before Vivek created the controversy. While some called it a mere co-incidence, some felt it to be Amitabh’s strong “sixth sense”.”Must say that AB’s tweets have prophetic tendencies. He had put out a tweet shortly before Sridevi’s death, and this tweet was put at 12:07 pm & at 1:23 pm Vivek Oberoi tweeted about Aishwarya Rai, Salman Khan & Abhishek Bachchan,” one person replied to Amitabh’s tweet. A lot of people agreed to it as well.It is to be mentioned, something similar had happened before Sridevi’s death. Just a few hours before the news of Sridevi’s death had broken, he had made a tweet that many felt was a premonition from the megastar.Just a few hours before Sridevi’s demise, Amitabh had made a tweet expressing a sense of unease. While Vivek eventually deleted his tweet and apologised for it as well, he might have refrained himself from making this tweet if he had seen Big B’s advice. Just some time before Vivek made the tweet, Amitabh  tweeted advising people to be careful with their posts on social media.”Social media par soch samajh kar zikr karo, ae-dost, kahin saamajik aitabaar se gair munaasib na ho,” his tweet in Hindi read.last_img read more

New gun laws will make NZ safer says PM Ardern

first_imgNew Zealand prime minister Jacinda Ardern meets representatives of the Muslim community at Canterbury refugee centre in Christchurch, New Zealand 16 March, 2019. Photo: ReutersNew Zealand prime minister Jacinda Ardern said on Monday she would announce new gun laws within days, after 50 people were killed in mass shootings at two mosques in the city of Christchurch.Australian Brenton Tarrant, 28, a suspected white supremacist, was charged with murder on Saturday. Tarrant was remanded without a plea and is due back in court on 5 April where police said he was likely to face more charges.”Within 10 days of this horrific act of terrorism we will have announced reforms which will, I believe, make our community safer,” Ardern said at news conference after her cabinet reached in principle decisions on gun reform laws in the wake of New Zealand’s worst ever mass shooting.In addition to the 50 killed, dozens were wounded at two mosques in the South Island city during Friday prayers.The owner of a New Zealand gun store the man charged with murder in the mosque shootings had bought firearms and ammunition online from the store, but it did not sell him the high-powered weapon used in the massacre.Gun City owner David Tipple said the alleged gunman bought four weapons and ammunition between December 2017 and March 2018.”The MSSA, military-style automatic, reportedly used by the alleged gunman was not purchased from Gun City. Gun City did not sell him an MSSA, only A-category firearms,” Tipple told a news conference in Christchurch.Under New Zealand gun laws, A-category weapons can be semi-automatic but limited to seven shots. Video of a gunman in one mosque showed a semi-automatic with a large magazine round.Tipple said the online purchases followed a police-verified online mail-order process and A-category firearms were bought in three or four purchases.”We detected nothing extraordinary about the licence holder. He was a brand new purchaser, with a brand new licence,” he said.The shock of the attacks has led to calls for an immediate tightening of laws to restrict access to some firearms, particularly semi-automatic weapons.Tipple said he supported Ardern’s call for gun law reforms as the Christchurch shootings had raised legitimate concerns.New Zealand, a country of only 5 million people, has an estimated 1.5 million firearms. The minimum age for a gun license is 16, and 18 to own a semi-automatic weapon.A Radio New Zealand report, based on police data secured through an Official Information Act request, said more than 99 per cent of people who applied for a firearms licence in 2017 were successful.A New Zealand standard A-category firearm licence is issued after a police and background check. No licence is required to buy a large round magazine, which can be illegally modified for use in such a weapon.Only firearm owners are licensed, not weapons, so there is no monitoring of how many weapons a person may possess.New Zealand’s top online marketplace Trade Me Group said it was halting the sale of semi-automatic weapons in the wake of Friday’s attack.BURIAL FRUSTRATIONSArdern was the first signatory of a national condolence book for the country’s worst mass killing that she opened in the capital Wellington on Monday.”On behalf of all New Zealanders, we grieve together. We are one. They are us,” she wrote in the book.Frustration was building among the families of victims as under Islam it is custom to conduct burials within 24 hours, but bodies will not be released until post mortems are carried out.Deputy police commissioner Wally Haumaha said the first body was approved for release on Sunday night, but the family was yet to take the body because another relative was also killed and they wanted to collect them together. He said there would be no burials on Monday.”We’ve been working fairly hard through the night to ensure the process of returning the deceased to their loved ones is taking place expediently,” he said.The burial process, which usually involves washing with three kinds of water, salving wounds and scrubbing skin, would be complicated, volunteers in Christchurch said.Mo, a volunteer who had flown in from Brisbane to wash the bodies, said the people who died in the mosques were classified as martyrs. That meant there were different views as to whether they would be washed or not because he said Islamic jurisprudence said martyrs are not to be washed as their blood was witness to their martyrdom.”But some people have said because it was not a battlefield it is okay to wash the body. But it is at the discretion of the family,” said Mo. He asked to be identified by just one name. The two mosques involved in the shootings have been closed since the massacre, but are expected to reopen by Friday prayers after cleansing blessings were carried out, said Haumaha.Muslim leaders conveyed messages of love, compassion and appreciation for the community support they had received.Over the weekend and into Monday, tens of thousands of people flocked to memorial vigils around New Zealand and a victim support website raised more than NZ$5.5 million ($3.8 million).Hundreds visited the sites of the shootings, performing songs, bringing flowers and food, and offering condolences.”Through all of this we try to remember that what we are bringing back to this tragedy, this horror, is a sense of compassion,” Rehanna Ali, coordinator of women’s affairs’ at the Federation of Islamic Associations of New Zealand, told a news conference. “The response to so much hate, has been love.”last_img read more

Thornton; Command Sergeant Major (Ret.) Wilson J. Thornton Jr.; and Earl William Nesbitt, well-known and longtime veterans advocate was honored posthumously.A special message came from Vice President Adrian Muldrow calling those in attendance to action.Baltimore City State’s Attorney-elect Marilyn Mosby delivered a rousing key note speech that had everyone on their feet with her “I am a byproduct of the history and work of the NAACP.” She said, “We have accomplished much but there remains much to be done and we need to be members, supporters and partners with the Baltimore City NAACP.”President Hill-Aston said she couldn’t have been more pleased with the turn out and the whole banquet. “There was so much energy in the room and many people were congratulating us on securing the 2017 National NAACP Convention for Baltimore. We spend the bulk of the year working on very serious and important issues. It was good to relax, sit back and have a good time for a great cause,” she said.Among the dignitaries present were Rep. John Sarbanes, the Rev. Jerome Stephens with Sen. Ben Cardin’s Office and Michele Brown, representing Sen. Barbara Mikulski.  In addition to honoree, Del. Carter, Del.

Writing Patterns on Carbon Nanotubes With Polymer Chains

first_imgThe alternating pattern of PE and PEO formed on single-walled carbon nanotubes with a 12-nanometer period imaged using transmission electron microscopy. The dark and bright stripes represent the PEO and PE domains, respectively. Image courtesy Christopher Li. Plumbing Carbon Nanotubes Now, as reported in a recent edition of Nature Nanotechnology, a research group has successfully used polymers to create well defined patterns onto single-walled carbon nanotubes.“Very few reports have address periodic patterning on nanotubes, and those studies that have been conducted resulted in patterns that were poorly repeating rather than nicely periodic and uniform,” said the study’s corresponding researcher, Christopher Li of Drexel University, to PhysOrg.com. “The success of our work appears to be in the polymer material we used.”The group chose a block copolymer, a polymer chain formed by two (or more, in some cases) short polymer chains. In this case the two components are polyethylene (PE) and polyethylene oxide (PEO).Li and colleagues at Drexel deposited a single-walled carbon nanotube solution onto a pre-fabricated carbon-coated grid. The nanotubes lined up on the grid surface and the group decorated the nanotubes with a solution containing the copolymer. The result is a copolymer/nanotube hybrid, which the group analyzed using a transmission electron microscope.Even with the powerful microscope, the nanotubes were not visible under the copolymers, which formed worm-like structures with alternating dark and bright stripes (corresponding to the PEO and PE blocks, respectively). But the consistent spatial orientation of the stripes, and the size of the “worms,” averaging 50 nanometers wide and one micrometer long, indicate that the polymer chains forming the stripes had aligned with the long axes of the nanotubes; the stripes, then, cut across the nanotubes perpendicularly.The researchers used copolymer solutions of varying concentrations and found that the stronger the solution, the more stripes formed on each nanotube. The process causing this to occur, they propose, begins when the copolymer molecules randomly adsorb onto a nanotube surface. These molecule clusters nucleate the growth of crystals and, with increasing concentration, more crystals appear, growing into larger patches.At a critical concentration the patches connect and clear stripes begin to form. And when the concentration is too high, there are so many crystals forming on the nanotubes that they don’t have time to align properly.The period of the stripe pattern – that is, the distance between alternating stripes – is about 12 nanometers. This regularity is a key step toward fabricating multiple transistors on individual nanotubes.Additionally, the group was able to attach gold nanoparticles to the copolymer/nanotube hybrid structures in fixed locations, adding another functional element to the pattern. This shows that it is possible to pattern other structures onto the nanotubes, a route toward tailoring them specific tasks in nanoelectronics.More information: Bing Li, Lingyu Li, Bingbing Wang and Christopher Y.

(PhysOrg.com) — Carbon nanotubes are at the center of the nanoelectronics research movement, with scientists making great progress toward getting nanotube-based electronic devices into the hands of consumers. But one area of carbon nanotube research where there has been considerably less success is creating repeating, regular patterns onto individual nanotubes, a task necessary for a key goal of nanoelectronics: patterning transistors directly onto nanotube surfaces.

Cricket mania looms large

first_imgAs the eighth edition of Indian Premier League concluded with the Mumbai Indians taking home the crown for the second time post a massive 41-run victory over two-time champions Chennai Super Kings, the IPL fever is refusing to die out among cricket fanatics. Despite being a punching bag for critics, who see it as nothing but cheap commercialisation of the game, the ground reality is strikingly different with its ever surging viewership according to TAM ratings. Also Read – ‘Playing Jojo was emotionally exhausting’The tournament continues to be hugely popular among children, who are not bothered by the controversies surrounding the tournament and watch it to get their dose of entertainment. The conclusion of this season, however, has created a void and has left many miserable as no major sporting tournament is scheduled to catch their fancy anytime soon, India being majorly a cricket loving nation.Sarthak Saini, 16, has mixed feelings over the ending of this season. He is ecstatic as his favorite team has taken the title, but at the same time gloomy as the good times have ended. “This season of the IPL has been special as my favourite team has won the title. But there is nothing interesting to catch up on television now,” he said. His opinion is similar to that of Vaibhav, 15, a CSK fan and budding cricketer. He said, “Although CSK eventually lost, overall the tournament has been exciting. I have watched almost every match since the beginning of my summer holidays and now the rest of my vacation is going to be quite boring.” Also Read – Leslie doing new comedy special with NetflixOn the other hand, Ayachi, 22, does not care much.” I supported KKR and lost interest in the tournament once they were out. I am disappointed, but hope to see them buckle up for next season. Being a sports aficionado, I have much to look forward to with the French Open in tow”, she said.The Indian Cricket team has a packed schedule this year. The team would be heading to Bangladesh for a test and then leave for the Zimbabwean shores in July to play a bilateral series comprising three One Day Internationals and two T20 ventures. However, both these series cannot match up to the excitement of IPL for youngsters. However, 15-year-old Smriti Jha said: “I am waiting for the series against Pakistan in December as that promises some real action.”  The reason for IPL’s high popularity among children seems to be its perfect amalgamation of cricket, glamour and entertainment. The tournament also gives fans a chance to see their favorite players from across the world on the same platform. “Although IPL cannot compete with other formats of Cricket in terms of standard, still I like it because it gives me an opportunity to see the likes of Kohli, De Villiers and Gayle playing together”, said Sanjeev,19, a diehard RCB fan. Since its inception, the tournament has been raising bars and has touched pinnacle this year. Although the cricket extravaganza has ended for this session, it promises to be back with a bang next year. Wait for the action!last_img read more
