An Upper Mesozoic island-arc–back-arc system in the southern Andes and South Georgia

first_imgThe Upper Jurassic–Lower Cretaceous strato-tectonic belts of the southern Andes and South Georgia, 2000 km apart, can be correlated and explained as the products of an island-arc–back-arc system. From the Pacific Ocean to the Atlantic, these belts, which exhibit structural and metamorphic differences, are: (1) a pyroclastic belt developed on an ensialic volcanic arc; (2) a back-arc flysch sequence underlain in the southern Andes by a basic complex with oceanic affinities; this was intruded into continental crust as a result of sea-floor spreading which created a marginal basin; (3) a slate sequence deposited on a continental shelf. The pyroclastic and marginal basin belts and the adjacent part of the continental shelf were folded and uplifted during the early Upper Cretaceous, whereas the foreland part of the continental shelf assemblage underwent deformation during the early Tertiary.last_img read more

Pearson blasts ‘arrogant’ Dean

first_img Press Association Rock-bottom Leicester were in the ascendancy at that point, only for the game to be changed as David Nugent was adjudged to have fouled Danny Rose, allowing Kane to slot home from the penalty spot. Despite a Jeff Schlupp own goal and Nugent’s strike coming after that, it was Dean’s decision to award a penalty which Foxes boss Pearson felt was decisive. “Unfortunately again, another dubious decision,” he told Sky Sports. “The arrogance of the man at times is frightening. “I just find it difficult to accept that we have to deal with yet another contentious decision that has not gone our way. “I am sure Spurs will be feeling, even though they scored four goals, quite relieved in their dressing room. “Now it is nine games and it remains a very frustrating season for us because of the level of performance, yet we’re just not getting over the line with results.” Pearson was perplexed as to why Dean awarded a penalty and also the amount of time it took the referee to make the decision. “I am led to believe nobody else’s opinion was actually involved,” he said. “He took that length of time to decide that two players colliding in the box is a penalty. White Hart Lane bore witness to a thrilling, end-to-end encounter on Saturday, with star turn Kane capping a wonderful week with his first Premier League hat-trick as Spurs ran out 4-3 victors. The result may have been positive but the home side were far from comfortable winners, with Jamie Vardy and Wes Morgan cancelling out the two-goal lead Mauricio Pochettino’s side had built up. “I just find it bizarre – that’s probably the nicest thing I can say. “We’re in a situation where there is a lot of talk about the spirit of the game, players going around referees. There has to be an element of fairness. “I really do feel at the moment that we continue to be short-changed. I am not suggesting, of course, that it is deliberate but we can’t be on the receiving end of so many poor decisions.” Asked if Pearson would seek out Dean to discuss things, he retorted: “What’s the point? What is the point of talking to him? He is one of the most arrogant men I have ever met. There we are. “I will concentrate on what I can affect and that is my players. I will try and keep my words carefully chosen this week and hopefully your microphone will be out of the way when I choose to say something different.” Pearson was still clearly angry by the time he spoke at the post-match press conference, during which he admitted he was not sure whether his comments would incur the wrath of the Football Association. Tottenham counterpart Mauricio Pochettino, by contrast, cut a more relaxed figure after Kane inspired his side to victory before joining up with the England squad for the first time. “I think it was a fantastic, fantastic game, a fantastic performance,” the Spurs head coach said. “I am very pleased for him, for his first hat-trick in the Premier League. “I think Harry is (only a) part of Tottenham, but I am happy for him. We worked hard today in a difficult game, but it’s true Harry is a very important player for us.” It was a positive result, if not performance, from Spurs, who had to do without Hugo Lloris from the first minute onwards after the goalkeeper collided with team-mate Kyle Walker. The France goalkeeper left the field on a stretcher after several minutes of treatment on a gashed knee which could keep him out of their upcoming international fixtures. “He’s in hospital with the doctor and we wait for news,” Pochettino said. “He got a big cut on the tendon of his knee. We hope it’s nothing big.” Leicester manager Nigel Pearson labelled referee Mike Dean “one of the most arrogant men” he has ever met after awarding a game-changing penalty against Harry Kane-inspired Tottenham.last_img read more

First legislative hearing for governor’s Invest in Iowa Act

first_imgDES MOINES — The sweeping tax plan Republican Governor Kim Reynolds calls the “Invest in Iowa Act” got its first hearing at the statehouse this week.It would raise the sales tax to fill a state fund for outdoor recreation and water quality projects. Dustin Miller with the Iowa Chamber Alliance said that part of the plan could help with the state’s workforce shortage.“One of the ways to attract talent to the state is to provide resources for placemaking,” Miller says, “and making attractive places people want to come to.”The plan would also lower income taxes and see the state take on more of the costs of mental health services that are paid now by property taxes. Peggy Huppert with the National Alliance on Mental Illness Iowa supports the plan, but urged legislators to make sure the new limit on property tax funding can be lifted if state support dwindles.“We are concerned about imposing this very low cap on counties and then them not having any recourse if the state does not live up to their end of the bargain,” Huppert said.Business groups expressed support for the income tax cuts, but asked lawmakers to also lower corporate taxes. Others are concerned about changes in the natural resources funding formula and warn there isn’t enough accountability built into water quality programs.The governor is holding more town hall meetings in Harlan and Council Bluffs tomorrow to discuss her Invest in Iowa Act.last_img read more

Organisers to blame for Bolt’s collapse – team-mates

first_imgLondon, United Kingdom | AFP |  Usain Bolt’s dramatic and inglorious end to his top level career was the fault of world championship organisers, his furious team-mates claimed.The 30-year-old 100 metres and 200m world record-holder collapsed on the London Stadium track whilst anchoring Jamaica in the final of the 4x100m on Saturday as cramp gripped his leg.Bolt lay prone on the track but waved away the offer of a wheelchair and eventually, aided by his three team-mates, limped across the line before making a hasty exit — not the way the man who had won triple Olympic gold at the same stadium in 2012 would have wished his competitive career in championships to finish.But his team-mates complained that his problem was caused by organisers keeping the relay teams waiting in the cold before their race as several medal ceremonies were held.“I think they were holding us too long in the call room. The walk was too long. Usain was really cold. In fact Usain said to me, ‘Yohan, I think this is crazy. 40 minutes and two medal presentations before our run’,” said Yohan Blake, who branded the wait as “crazy”.“We kept warming up and waiting, then warming up and waiting,” added the 2011 100m world champion, who also won Olympic relay gold in 2012 and 2016 with Bolt.“I think it got the better of us. We were over warm.“To see a true legend, a true champion go out there and struggling like that.“The race was 10 minutes late and we were kept 40 minutes.”Bolt may not have led Jamaica to a glorious finale anyway, though, as he took the baton well behind eventual winners Great Britain and the US. Share on: WhatsApp But Jamaica’s 110m hurdles world champion Omar McLeod — who ran the first leg — likewise pointed the finger at organisers for denying his country’s greatest star a more fitting swansong.“It’s heart wrenching,” said McLeod, who is also the Olympic champion.“It was ridiculous man, we were there around 45 minutes waiting outside, I think they had three medal ceremonies before we went out so we were really trying our hardest to stay warm and keep upbeat.“But it was ridiculous. We waited a really long time. I drank like two bottles of water.”Their criticism echoed that of Justin Gatlin, who led an American 1-2 alongside team-mate Christian Coleman to deny Bolt a farewell gold in the individual 100m.“I think it was the elements. I am sorry he got this injury. He is still the best in the world,” said Gatlin.“It was a recipe. I don’t want to say this, I understand we need to be ready early, but I think we took our clothes off a little too early.“It’s a little chilly in here so I think that’s where the cramp came from. That’s what he suffered with. He was running out there cold.”Despite his relatively unsuccessful championships — in which he will exit with just a single bronze medal — Bolt will still be accorded a final lap of honour in a tribute ceremony before the curtain comes down on the world championships later on Sunday.last_img read more

Portsmouth boss Whittingham defends fans after pitch invasion

first_imgPortsmouth manager Guy Whittingham leapt to the defence of supporters who invaded the pitch at full-time at Griffin Park.Hundreds of away fans stormed onto field at the final whistle after their side conceded two late goals to lose 3-2 against Brentford.But Whittingham insisted it was done in celebration, given that ownership of the club has been secured by supporters after a long period in administration.“No-one wants to see that happen but it is not done in a violent way,” he said.“It is done because they are celebrating the club and I hope people appreciate that, because it’s about the euphoria surrounding things at Portsmouth at the moment.“The situation at the club has not been going on for the last 13 or 14 months, it’s been happening for four years, and unfortunately things spilled onto pitch at the end.”Whittingham added: “To have your own supporters run the club is what everybody wanted and hopefully the club can finally turn the corner now.“We know there is every chance we will be in League Two next season but we know even from that we can build on and push forward again.”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 Follow West London Sport on TwitterFind us on Facebooklast_img read more

Insect Wings Are Rainbows of Color

first_imgScientists in Sweden have found that a feature of transparent insect wings – their shimmering colors – may have a purpose.  They are not just accidental patterns like the rainbow colors of oil on water, but are stable structures genetically determined for insect recognition and mating.  They call them “wing interference patterns” (WIP) but their evolutionary explanation for them appears to be a work in progress (WIP).    Publishing in PNAS,1 the team said that these color patterns “have been largely overlooked by biologists” even though they have been known since before Darwin.  Like the oil-on-water effect, “These extremely thin wings reflect vivid color patterns caused by thin film interference,” but the effect in insects is not accidental.  “The specific color sequence displayed lacks pure red and matches the color vision of most insects, strongly suggesting that the biological significance of WIPs lies in visual signaling.”    The patterns, they found are not just genetically stable, but are reinforced by additional structures, such as “membrane thickness, pigmentation, venation, and hair placement.”  They continued, “The optically refracted pattern is also stabilized by microstructures of the wing such as membrane corrugations and spherical cell structures that reinforce the pattern and make it essentially noniridescent over a large range of light incidences.”  Their paper is loaded with dazzling color images of various insect wings.  They feel this largely-overlooked feature of Hymenoptera (bees, wasps) and Diptera (flies) can serve as a species identifier and a potent source of experimentation on genetic control of wings.    The authors had a lot to say about evolution.  They ascribed these coloration patterns to sexual selection, but it was clear their thinking was largely unformed and tentative: “The WIP is potentially a major contribution to the toolbox for evolution of small insects with transparent wings and thus an important piece of the evolutionary puzzle, they said at the end of the paper.  Apparently no other biologist has examined these features of insects before in evolutionary terms.Update 01/13/2010: Live Science posted an article and photo album about this phenomenon that they said was “hidden in plain sight” from scientists.  One researcher at the University of Lund said, “one day you handle a specimen, which you may very well [have] seen before, and suddenly you notice the wing pattern, which is beautiful and perfect, like an art painting.”  A colleague responded when shown these patterns, “It was like the world I knew suddenly was turned upside down and a totally new character system was sparkling from every wing of the flies I had been working with for years without really noticing.”  But then he said, “We find it hard to believe that insects walk and fly around with wings that can be turned on to large (to them) flashing billboards without evolution picking up on it.”  The article later acknowledged that evolution of these art paintings is not straightforward from the evidence: “They also hope to learn whether evolution drives changes in the color patterns,” putting any scientific understanding into future tense.  For now, “The study is an example of old-fashioned science yielding new information,” he said.1.  Shevtsova, Hansson, Janzen and Kj�randsend, “Stable structural color patterns displayed on transparent insect wings,” Proceedings of the National Academy of Sciences, print January 3, 2011, doi: 10.1073/pnas.1017393108 (open access).One thing is clear: insects did not decide to “evolve” this capability, nor did “evolution” as if it was some purpose-driven goddess.  Yet again and again, the authors spoke of evolution as a purposeful agent with a toolkit for getting things done.  We need to kick some butt about misuse of terms in evolutionary theory.    The patterns truly are beautiful; you should look at the images in this open-access paper.  In creation, things are often functional as well as beautiful.  You yourself should be useful as well as ornamental.  For a new year resolution, work on whichever part is not optimum.(Visited 12 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
