It means River prevailed 5-3 on aggregate after the first leg finished 2-2 and the club reclaim the trophy they had last won in 2015, lifting it for the fourth time in their history.Postponed on three occasions and then relocated from Buenos Aires to Madrid, the supporters of these two great clubs showed in the Santiago Bernabeu why this fixture had been billed as one of football’s greatest ever.Lionel Messi, Antoine Griezmann and Diego Godin were among the 62,200 in attendance.But, despite the bouncing huddles in the streets, the plumes of blue and red smoke, the swinging scarves, fluttering flags and fans that were chanting in their seats three hours before kick-off, there was nothing to extinguish the lingering sense of regret.There was no repeat of the scenes that cast a shadow over Argentinian football and saw the original game at River’s El Monumental on November 24 postponed, when around 50 fans attacked Boca’s team bus and left some of their players injured.Madrid, which will also host the Champions League final in June, was chosen in part because of its record of hosting major events and the security, which included around 2,500 police officers, did its job before kick-off.Fans were separated into zones either side of the stadium and had to go through checks even to enter the area immediately surrounding it.The shame was only that the operation was not as thorough 15 days ago and that a minority decided to take advantage.– Raucous atmosphere –Both clubs were allocated 25,000 tickets, with 5,000 of those reserved for residents of Argentina. The fear had been most of those buying would be tourists and neutrals, but the atmosphere suggested different.Both teams had initially refused to play in Spain’s capital but as the losers, Boca’s sense of grievance will now become more entrenched.They felt River were responsible for the chaos two weeks ago and should have forfeited the trophy. They took their case to the Court of Arbitration for Sport, but the appeal was rejected on Saturday.When the players shuffled out two hours before kick-off to inspect the pitch, they held up their phones to capture the thousands already inside and the view of a stadium most of them had never played in before.The cheers grew louder when they came out for kick-off. Then there were whistles as the teams swapped ends and each were greeted by their opponent’s fans behind the goal.Jonatan Maidana was playing for Boca when they last won the Copa Libertadores 11 years ago and, now in the red and white of River, he almost gave his former club an early lead, slicing just over his own crossbar.The game lacked quality but came alive one minute before half-time. Nahitan Nandez’s superb pass split two River defenders and Benedetto kept a cool head, guiding into the corner, before taunting the beaten Gonzalo Montiel.River had been inferior but improved. Their first real attacking move was also a brilliant one as Leonardo Ponzio and Quintero exchanged passes before the latter pulled back for Pratto to sweep home.The game meandered towards full-time and seemed destined for penalties until Quintero intervened. It was a goal worthy of winning the tournament, as he collected 25 yards out, glanced up and whipped the ball in off the underside of the crossbar.Leonardo Jara almost snatched a late Boca goal but his shot nicked the outside of the post. Then, with goalkeeper Esteban Andrada up for a corner, River added the final touch.Martinez ran the ball into the empty net and River’s substitutes and staff all poured onto the pitch to begin the celebrations.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000A brilliant goal by Juan Quintero steered River Plate to a fourth Copa Libertadores crown © AFP / Javier SORIANOMADRID, Spain, Dec 10 – River Plate won the Copa Libertadores by beating their fiercest rivals Boca Juniors 3-1 after extra time on Sunday, bringing an end to a final tainted by violence and moved more than six thousand miles away from Argentina.Boca took the lead through Dario Benedetto but Lucas Pratto equalised before Juan Quintero and Gonzalo Martinez both scored in extra time to win a fittingly dramatic contest for River.
But Allardyce has given his backing to under-fire Sterling and believes Southgate will stick with the same XI that has got the Three Lions this far.“I wouldn’t change it, not now,” the former Three Lions boss said on Monday’s Alan Brazil Sports Breakfast“Gareth has decided that is his strongest XI and it’s got them this far, so why change it now?“I think Raheem Sterling will play. The only thing Sterling has failed to do is score a goal and, at the end of the day, all the front lads have failed to score from open play. They haven’t scored many – we’ve been a set-play team. 2 2 “I wouldn’t see Gareth changing it now. I wouldn’t see him changing the system. I’d see him going in with full confidence, resting those players up and saying, ‘off you go lads, get us to the final’.Allardyce says the final is well within England’s grasp, telling talkSPORT the Three Lions have ‘more confidence and more talent’ than their semi-final opponents.“Of course we can make the final,” Big Sam added.“Having watched Croatia against Russia, and seeing that their last two games both went to extra-time and penalties, we know they have some talent but I think we have more confidence and more talent than them.“Perhaps they are stronger in midfield than us, but I can’t see anywhere else where they are stronger than we are.“The confidence England have at the moment and looking at the Croatia side, I think we are favourites.“Let’s hope we can live up to that reputation and do the business.”Tune into talkSPORT for LIVE commentary of England v Sweden in the World Cup semi-finals: Wednesday July 11 – KICK OFF 7PM EST Southgate with England captain Harry Kane – who is still the top scorer at the World Cup Raheem Sterling is one of Gareth Southgate’s key England players, despite having struggled for goals in Russia Gareth Southgate will NOT change his system or starting XI for England’s upcoming World Cup semi-final against Croatia, believes former boss Sam Allardyce.The Three Lions beat Sweden 2-0 on Saturday to seal their place in the last-four of a World Cup for the first time since 1990.Only one England team in history has gone further in the competition than Southgate’s men – Sir Alf Ramsey’s 1966 champions – but many are calling for the boss to change his team for what appears to be their toughest test yet in Russia.It has been suggested England start with another holding player alongside Jordan Henderson to combat Croatia’s world-class midfield, which includes Real Madrid’s Luka Modric and Barcelona’s Ivan Rakitic.Some frustrated fans have also called for Marcus Rashford to replace Raheem Sterling after the Manchester City flyer wasted a number of goalscoring chances against the Swedes – continuing his England goal drought which stretches all the way back to October 2015.
Scientists at Lawrence Berkeley National Labs have produced a lightweight composite material 300 times stronger than its constituents. How? By taking inspiration from clams. The team, writing in Science,1 described nacre, the shiny mother-of-pearl found inside clam shells. Because of the way it sandwiches crystalline aragonite with layers of protein (07/26/2004), nacre resists cracks more and more as strain is applied. Here’s how the scientists marveled at this amazing material:A prime example is nacre, which consists of 95 vol. % of layered aragonite (CaCO3) platelets bonded by a thin layer of organic material, yet exhibits a toughness (in energy terms) some three orders of magnitude higher than that of calcium carbonate. The hard aragonite provides strength, but without a means to dissipate strain, nacre would be brittle; however, large inelastic deformation generated by interlayer shearing through the organic phase allows for such strain redistribution, so that toughness is achieved through viscoplastic energy dissipation in the organic layer associated with the controlled, yet limited, sliding of the aragonite layers over each other. Although there is controversy over the mechanisms that restrain sliding—resistance from the lamellae nanoroughness, plastic deformation of the aragonite at the nanolevel, the organic layer acting as a viscoelastic glue, or from the presence of mineral bridges—the resulting toughness is remarkable.Previous attempts to mimic this structure have only yielded strength increases about two orders of magnitude (07/05/2007). The Berkeley team applied “this natural concept of hierarchical design” to ceramics with new techniques that employ controlled freezing of seawater ice crystals in the layering process. The Lawrence Berkeley press release explained the process and has a picture of the roughened surface of the hybrid ceramic used in the manufacture. They not only mimicked nacre’s natural lubricant between layers, but its brick-and-mortar structure, as shown in a second picture. Of nacre, the press release said, “No human-synthesized composite outperforms its constituent materials by such a wide margin.” Everything they did was an “an attempt to replicate the microstructural design of nacre,” they said. Nacre is “the often cited ‘gold standard’ in biomimetic design.” Using ceramic alumina, they actually exceeded the toughness of nacre. “We believe that this result illustrates the importance of hierarchical design in promoting toughening mechanisms at multiple length scales as a way to create materials with unique combinations of strength and fracture resistance.” Nevertheless, they still respect the natural standard: “We believe that of the various hybrid materials that we have fabricated, this structure best mimics nacre.” They succeeded in sandwiching tough ceramics between microscopic deformable layers with limited shear. “The result is synthetic materials that, like nacre and bone, are far tougher than what could be expected from the simple mixture of their constituents.” Even so, natural nacre still has some unsurpassed qualities: “At present, our materials contain too much of the soft phase, and our ceramic layer thicknesses are still somewhat coarse in comparison to nacre,” they said; “indeed, a reduction in the polymer content and refinement of the ceramic layers should improve strength and provide additional nanoscale toughening mechanisms similar to those acting in natural materials.” How did they feel about biomimetics in general? “These results highlight the tremendous potential of the biomimetic approach and suggest promising strategies for structural optimization.” Materials science will continue to improve – thanks to the lowly clam.

(Visited 31 times, 1 visits today)FacebookTwitterPinterestSave分享0 As the orbs whirl around Sol, human understanding of our space neighborhood rises and falls.Mercury: The innermost planet has undergone a paradigm shift since the MESSENGER spacecraft arrived. Now, explosive volcanoes are prominent in explanations for its many flat-floored craters and volcanic plains, Robin Wylie discusses on The Conversation. Here’s his spin doctoring:Before its explosive nature surfaced, experts assumed that, having formed so close to the sun, Mercury would have been stripped of its volatile gases early on in its life. So future theories of Mercury’s genesis must now take into account how the planet kept its fizz hidden. They will likely now invoke ideas of ancient collisions with volatile-rich “planetesimals” – balls of rock and dust that are thought to have formed the inner planets – which could have topped up Mercury’s levels. All of this puts a new spin on the first rock from the sun, and its place among the others.Venus: Water at 900 degrees? Live Science reported that a revisit of 30-year old data from the European Space Agency’s Venus Express orbiter and ground data from Russian Venera landers suggests (indirectly) that water molecules might have survived in the planet’s mantle. Since those early days of exploration, scientists have dreamed of proving that Venus was once host to Earth-like lakes and oceans of liquid water before the climate went terribly bad.Earth and the Young Sun Paradox: How did the Earth stay warm when the early sun was 25% cooler than today? That old puzzle was revisted by Astrobiology Magazine. Astronomers are still working on the new spin. Maybe it was tiny bubbles in the wine of Earth’s early atmosphere: changes to the ratios of nitrogen, carbon dioxide and greenhouse gases. “We do have some choices for understanding the early atmosphere,” Bernard Marty said. It’s going to be tough to spin a solution out of the paradox, because as Earth was evolving, changes to the magnetic field, the atmosphere and the crust were evolving, too. Maybe noble gases helped: “We think that this implies that the xenon composition has been evolving through time and it was not fully in the atmosphere 3.5 billion years ago,” Marty said.Mars: See the 2/13/14 entry for Mars news.Asteroids: A paper in Nature found “unexpected diversity” of asteroid composition in the asteroid belt. This undermines the idea that a single body disrupted in that orbital region. “The asteroids in the main asteroid belt have been discovered to be more compositionally diverse with size and distance from the Sun than had previously been known,” the abstract says. “This implies substantial mixing through processes such as planetary migration and the subsequent dynamical processes.”Jupiter’s Io: The volcanoes of Io have been popping off consistently for decades at least, a new paper on Icarus says. Based on comparative data from Galileo and New Horizons missions, the authors state this finding: “Most Ionian hot spots [are] very persistent on decade timescales.”Jupiter’s Ganymede: The largest moon in the solar system, Jupiter’s 3rd Galilean satellite Ganymede, got a new map published. Combining data from the Voyager and Galileo spacecraft, the new map shows a splotchy surface that PhysOrg displayed. The article did not mention any new findings, but connected potential water to potential life, as is customary for NASA press releases: “With its varied terrain and possible underground ocean, Ganymede is considered a prime target in the search for habitable environments in the solar system, and the researchers hope this new map will aid in future exploration.” As John Grotzinger pointed out last week, habitable does not mean inhabited. A paper in Icarus comparing Ganymede and Europa shows the difficulty in inferring crustal depths from crater characteristics.Saturn’s Titan: Three papers discussed Titan recently. One in Icarus tried to figure out how icy “sand” particles move around to form the equatorial dunes and infer something about the time involved. Another paper in Icarus tried to refine the distribution of methane in the atmosphere. A third paper in Icarus found that the equatorial dunes cover about 17% of the moon’s surface, and comprise the bulk of organics on Titan. One surprise involves dating: “Dunes are the largest visible surface reservoir of hydrocarbons and may be less than 730-Myr old.” That would be just 16% of Titan’s assumed age.Saturn and rings: Another stunning photo of Saturn’s north polar vortex, shaped like a hexagon, was published by Space.com. Atmospheric scientist Andrew Ingersoll said that vortices like these are “notoriously turbulent and unstable,” yet this one has been spinning at least since Voyager’s flybys in 1981. A photo of little potato-shaped moon Prometheus is shown by PhysOrg pulling on the F-ring. “It’s a visual demonstration of gravity at work!” the article exclaimed. Icarus described a bit of “calm amidst the chaos” in this ephemeral ring of tiny ice particles, predicting a narrow, stable zone in the core of the ring. How can that be, with Prometheus and Pandora constantly tugging on it? “Essentially, we find that the F Ring core is not confined by a combination of Prometheus and Pandora, but a combination of Prometheus and precession.” How stable over time that arrangement could be is not clear; it seems like a tenuous balance. Astrobiology Magazine published an overview of “Cassini’s View of Weird & Wonderful Saturn,” ending with a prediction of the spacecraft’s daring attempt to “shoot the pier” in 2017 before it plunges into the gas giant.Extrasolar planets: Now that planets around other stars are becoming commonplace, what’s new with them? On PhysOrg, Caltech astronomer Fraser Cain discussed “What are hot Jupiters?”. In text and video, she explains how new theories of migration were invented to account for the unexpected observation of gas giants orbiting their stars closer than Mercury to the sun every 2-3 days. Asked how they got there, she said, either the dust disk in which they formed created a torque pulling them in, or they got slingshotted in by interactions with other planets. Those are just some theories they’re working on.Extrasolar moons: Space.com claims that extrasolar planets may not need a big moon to support life. Jack Lissauer at NASA-Ames found in computer simulations that changes to obliquity without a large moon were not as dramatic as previously calculated. “For timescales that are relevant to advanced life, it changes by maybe plus or minus 10 degrees — a lot bigger than we have with our moon, but a lot smaller and a lot fewer climate effects [than predicted by previous models],” he said. Still, this is only a simulation. “We’re not talking about, really, the Earth without the moon as a realistic model for the Earth, unless somebody goes out there and destroys the moon,” he said. “We’re using this as the first case of studying a plausible exoplanet, and we’re going to use some future calculations — we’re going to do the same thing with other systems.”Good time to recall Finagle’s Second Law: “No matter what the experiment’s result, there will always be someone eager to: (a) misinterpret it, (b) fake it, or (c) believe it supports his own pet theory.” Planets spin, and so do their spin doctors. Ask them, “What do you know?” and you get a much smaller subset of verbiage. This is confirmed by the number of times previously held beliefs have been overturned.This is also a good time to remember Ken Ham’s debate argument contrasting observational science and historical science. Despite Bill Nye’s denials, there is a difference (see also Todd Friel’s explanation on Wretched TV). We can observe hot Jupiters, but we cannot retrace how they got there. We can see Saturn’s F-ring, and dunes on Titan, but nobody was there to see how they got that way. All one can do is model it, or create a plausible story that doesn’t violate known physics. That being the case, alternative models should be welcomed, and any consensus view must be humbly considered tentative.
oklahoma state phantom first downIt’s been a tough year for the the Big 12’s referees. It’s about to get worse.During Saturday’s contest between Oklahoma State and Kansas State, it appears that the Cowboys were given a phantom first down when they should have been four yards short of the line to gain. Facing a 3rd and 23 from Oklahoma State’s 42-yard line, Mason Rudolph connected with Marcell Ateman for a 19-yard gain. Fox Sports 1 showed a replay of the play, and when they panned back to the live action, OSU had somehow been given a first down.A user took video of the entire sequence. The play in question comes at around the 2:30 mark.Jake Trotter, who covers the Big 12 for ESPN, confirmed that the officials made a mistake. As he notes, Oklahoma State scored a touchdown just four plays later.Big 12 officials did in fact award Oklahoma St a phantom first down when it should’ve been fourth-and-four. OSU scored TD four plays later— Jake Trotter (@Jake_Trotter) October 4, 2015How does this happen? We’re not sure. But with the Cowboys eking out a two-point win over the Wildcats, there are going to be lots of questions here.
TOKYO — A Japanese news report says former Nissan chairman Carlos Ghosn will be detained at least through Jan. 11.Ghosn, who led Nissan Motor Co. for two decades saving the Japanese automaker from near bankruptcy, was arrested Nov. 19 on suspicion of falsifying financial reports.He also faces a breach of trust allegation, for which his detention had been approved previously through Jan. 1.Kyodo News said the Tokyo District Court approved prosecutors’ request for a 10-day extension on Monday.The court was not immediately available for comment. Much of the nation’s government offices are shut down for the New Year’s Eve and New Year’s holidays.Ghosn has been charged in the first set of allegations, about under-reporting Ghosn’s pay by about 5 billion yen ($44 million) in 2011-2015.The Associated Press
NDP environment critic Marlin Schmidt said Alberta repealing its tax is an abdication of responsibility.“They’re just going to scrap the carbon tax, let everybody else deal with the fallout, and turn over the responsibility for climate change and all the things people want to do in this province to Ottawa and Justin Trudeau,” said Schmidt.Also Tuesday, Kenney and the 62 other members of the United Conservative caucus were officially sworn in as MLAs. They join 24 members of the Opposition NDP caucus, led by Notley, who were sworn in last week.“It is my fervent hope that as legislators on all sides of the house that we can and will work together to stop the coarsening of our public discourse and to raise the bar of civility, decorum and respect in this _ the people’s house,” Kenney told the new members. The spring session under new Premier Jason Kenney and his United Conservatives begins Wednesday.There will be a speech from the throne to outline government plans, followed by the introduction of a bill to repeal the carbon tax.Repealing the act was the signature promise of Kenney’s successful election campaign. He says the tax was a frontline failure, making no impact on greenhouse gas emissions while taking money from Alberta families.The tax on fossil-fuel heating and gasoline at the pumps was phased in by former NDP premier Rachel Notley’s government in 2017 and has raised more than $2 billion.Much of that money was rebated to low and middle-income Albertans while the rest funded a range of green projects ranging from solar panels and energy-saving light bulbs to light rail transit construction.Once the tax is repealed, the federal government has indicated it will introduce a federal carbon tax in Alberta as it has done in other provinces that have balked at bringing in their own carbon levies. EDMONTON, A.B. – On the eve of Alberta’s carbon tax heading to the chopping block, the province’s environment minister says green projects currently being funded by the levy will go ahead.But Jason Nixon says once the Carbon Tax Repeal Act is passed and implemented by May 30, there will be nothing new.“Projects that have already been approved will continue, but going forward no, they won’t,” Nixon, who is also the government house leader, told reporters Tuesday. Members also elected the UCP’s Nathan Cooper as the new Speaker of the house, replacing Bob Wanner.Cooper, representing the riding of Olds-Didsbury-Three Hills, defeated NDP candidate Heather Sweet in a secret ballot.He was then ceremonially dragged to the Speaker’s chair by Notley and Kenney as part of a tradition of forcing someone to take on the unenviable job.Asked how he will keep debate respectful and honourable in a chamber known for fiery outbursts, the 39-year-old joked: “I’ll try my very best dad voice.”Cooper said it will be a process of trial and error for both him and the politicians.“Over a period of time, I hope that I’ll find my groove and be able to be effective yet also provide a sense of tradition to the assembly.”
Kuala Lumpur: Malaysia Airlines may be sold or shut down, Malaysia’s leader said Tuesday, the latest bad news for a carrier that has been in crisis since suffering the loss of two planes. The 71-year-old airline has been on the ropes since 2014 when Flight MH370 disappeared and MH17 was shot down by a Russian-made missile over war-torn Ukraine. With the carrier teetering on the brink of bankruptcy, sovereign wealth fund Khazanah stepped in to take it over several years ago and major reforms were instituted, including cutting thousands of staff. Also Read – Maruti cuts production for 8th straight month in SepBut it has continued to fare poorly and its performance was blamed in large part for a set of poor financial results released by Khazanah last week. Responding to questions about the airline’s future, Prime Minister Mahathir Mohamad told reporters in parliament: “I think it is a very serious matter, to shut down the national airline. “We will nevertheless be studying and investigating as to whether we should shut it down or we should sell it off or we should refinance it.” Official news agency Bernama reported that Khazanah last week posted a pre-tax loss of 6.3 billion ringgit (USD 1.54 billion) for 2018, compared with a pre-tax profit of 2.9 billion ringgit the year before. Mahathir, 93 and in his second stint as premier, is seeking to reduce a mammoth national debt inherited from the previous, corruption-plagued regime.
Washington DC: No date has been set yet for a summit meeting between US President Donald Trump and his Chinese counterpart Xi Jinping, the White House said on Monday noting that the trade negotiations between the two countries still continues. “In terms of whether or not we have a date set, not yet. We’re continuing the negotiations with China.” “When we have an announcement for the two leaders to sit down, we’ll certainly let you know,” White House Press Secretary Sarah Sanders told reporters at her news conference. Also Read – Imran Khan arrives in China, to meet Prez Xi JinpingShe was responding to questions on reports that a summit meeting at Trump’s Mar-a-Lago resort in the US state of Florida has been put off as China considers the US President as “unreliable” in view of him walking away from talks with North Korean leader Kim Jong-un. Sanders ridiculed such a view. “I would say that’s absurd. The President is going to make a deal if it’s a good deal. He’s going to make a deal if it’s in the best interest of America. If he doesn’t feel like it’s a good deal, it’s not worth just signing a piece of paper,” Sanders Also Read – US blacklists 28 Chinese entities over abuses in Xinjiangsaid. She argued that the President didn’t feel like what was on the table was enough. “The President is 100 per cent committed to denuclearization of the Peninsula, and he’s going to make sure that whatever we do furthers that process.” “We’ll see what happens with North Korea, the same way we’re going to see what happens in the negotiations with China. They’re ongoing,” she said. Trump is going to make sure whatever deal the US gets is in its best interest — that it’s fair and reciprocal trade; that it protects intellectual property; and that it actually has safeguards to make sure that the Chinese follow through with whatever commitments that they make, Sanders said. The two leaders will sit down for talks only when the negotiations are complete, she asserted.
