Marseille’s Pele will attempt to shut out PSG’s superstar

first_imgHe has made several blunders lately but Stephane Cassard, Marseille’s goalie coach, insists he has full confidence in Pele.“He does not even have to prove his mental qualities anymore,” Cassard told AFP. “Just look at the number of clean sheets Yohann has in his career.”Last season, Pele held the opposition scoreless 18 times in 38 appearances for Marseille. His percentage is even better this season. In just eight games in all competitions, he has kept five clean sheets.Pele, who is 35, was sidetracked by ill health and missed most of three years after suffering a pulmonary embolism in 2010 while with Toulouse.Recently, Pele has been plagued by sporting rather than health worries.After coming on as a sub in Saint Etienne he allowed a cross to loop over his head to set up a goal that cost Marseille two points.On Thursday in the Europa League, he hit one clearance straight to an opponent. Braga could not capitalise on the chance and Marseille won comfortably, but such incidents can create doubt.– ‘Two great goalies’ –“Yohann showed what he can do over a whole season,” Cassard said. “He can take it. That’s why I first chose him.”Cassard and Franck Passi, a longtime Marseille coach who had a couple of spells as interim manager, brought Pele to the club in 2016.Cassard says that the player did not “even want talk about number one or number two.”“When one has experienced a serious illness, as he has, and been forced from the pitch for three years, and one succeeds in returning to the highest level, that says something. He can face anything.”“Yohann was backup to Steve Mandanda who had proved over nine years that he was a top goalie,” said Cassard.When Mandanda left for Crystal Palace, “few believed in Pele when he took over,” recalled Cassard.Mandanda returned in the summer. Having been, briefly, No.1, Pele became No.1b.“I have two great goalies,” said manager Rudi Garcia who also coached Pele for one season at Le Mans.“These are intelligent lads with lots of experience,” said Cassard. “Yohann knows why he is still at Marseille. We all get on well, there is no misunderstanding, the situation is clear”.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Modern day ‘Pele’: Marseille goalkeeper Yohann Pele is braced to face PSG on Sunday © AFP / JEAN-FRANCOIS MONIERMARSEILLE, France, Feb 24 – His famous namesake was the “King of Football”, but Marseille backup goalkeeper Yohann Pele will take a reputation as the “Prince of the clean sheet” into his encounter with the potent Paris Saint-Germain attack.Steve Mandanda has not recovered from his thigh injury so the “Albatross,” as Pele is known, will start at Parc des Princes on Sunday.last_img read more

Eating Meat Made Us Human

first_img(Visited 106 times, 1 visits today)FacebookTwitterPinterestSave分享0 Sorry, vegans; evolutionists tell us that eating meat 1.5 million years ago made us what we are today.In “Anthropologist Finds Evidence of Hominin Meat Eating 1.5 Million Years Ago: Eating Meat May Have ‘Made Us Human’,” Science Daily swallowed the evolutionary line without asking where’s the beef.  “A skull fragment unearthed by anthropologists in Tanzania shows that our ancient ancestors were eating meat at least 1.5 million years ago, shedding new light into the evolution of human physiology and brain development.”If meat eating made us human, what does that make T. rex?  Lots of animals ate meat.  Carnivores go way back.  Didn’t the anthropologist consider that?“Meat eating has always been considered one of the things that made us human, with the protein contributing to the growth of our brains,” said Charles Musiba, Ph.D., associate professor of anthropology at the University of Colorado Denver, who helped make the discovery. “Our work shows that 1.5 million years ago we were not opportunistic meat eaters, we were actively hunting and eating meat.“But lots of carnivores hunt their meat.  That’s what makes a carnivore a carnivore and not just a scavenger.  Is hunting meat what makes eagles human?Somehow Musiba built his conclusion on a malnourished juvenile “hominin,” as inferred from the skull fragment. The reader looks in vain for deeper thinking about this than the headline suggested.The study offers insights into the evolution of hominins including Homo sapiens. Musiba said the movement from a scavenger, largely plant-eating lifestyle to a meat-eating one may have provided the protein needed to grow our brains and give us an evolutionary boost.Some scientists have argued that we became human when we became carnivorous-omnivorous creatures.“Meat eating is associated with brain development,” he said. “The brain is a large organ and requires a lot of energy. We are beginning to think more about the relationship between brain expansion and a high protein diet.”Certainly a T. rex or a lion eats much more protein per ounce of brain than a human does.  How can Musiba say such things?  How can Science Daily publish it uncritically?  Musiba says that chimpanzees have smaller brains and eat less meat, but nowhere did he apply his notion to the large carnivores that have inhabited earth.He may be convinced of his hypothesis: he said that our meat eating “separates us from our distant cousins.”  But he also can’t explain why our ancestors went to the meat market: “The question is what triggered our meat eating? Was it a changing environment? Was it the expansion of the brain itself? We don’t really know.”This story is so full of baloney it’s hard to know where to start slicing.  First, he says meat eating made us human (ignoring all the other carnivores that ever stalked the earth).  But then he offers the idea that the expansion of the brain came first. This guy needs an evolutionary boost, all right; a boost out of the garbage bin he’s in.So let’s just take him at his word.  “We don’t really know”  (the “we” referring to himself and his fellow baloney sellers).  Science Daily knows even less, because the editors didn’t call him on it.  What do you do with people who don’t know what they’re talking about?  Ignore them.We can’t ignore the sad fact, however, that thousands of people read this kind of baloney and think it is wonderful science.Assignment: Feed meat to a guinea pig, wait a million years, and see if it starts writing books on logic.last_img read more

Moon Losing Its Water

first_imgThe moon loses more water than it receives from the solar wind or meteorites. How long has that been going on?Data analyzed from the LADEE mission, which orbited the moon 2013-2014 measuring the thin lunar atmosphere, has revealed something interesting: meteor impacts blast water out of the deep soil, where most of it is lost to space, never to return. Water? Yes; the moon has some. Lunar soil is drier than any soil on Earth, but it does retain some H2O and OH– (hydroxyl) ions, which chemists designate as water. Some water molecules can form from reactions with the solar wind.A video clip at the NASA Goddard website illustrates how LADEE connected meteor impacts to escaping water in “meteoroid streams” in the atmosphere:There’s evidence that the Moon has water (H2O) and hydroxyl (OH), a more reactive relative of H2O. But debates continue about the origins of the water, whether it is widely distributed and how much might be present.“The Moon doesn’t have significant amounts of H2O or OH in its atmosphere most of the time,” said Richard Elphic, the LADEE project scientist at NASA’s Ames Research Center in California’s Silicon Valley. “But when the Moon passed through one of these meteoroid streams, enough vapor was ejected for us to detect it. And then, when the event was over, the H2O or OH went away.”Crater Bruno on the moon.There’s more water three inches down (the “hydrated layer”) than in the top portion (“dessicated layer”) of regolith (lunar soil that has been “gardened” by small meteorites), so only larger meteors penetrate where the water is. Nevertheless, water escape is a continuous process:Because the material on the lunar surface is fluffy, even a meteoroid that’s a fraction of an inch (5 millimeters) across can penetrate far enough to release a puff of vapor. With each impact, a small shock wave fans out and ejects water from the surrounding area.When a stream of meteoroids rains down on the lunar surface, the liberated water will enter the exosphere and spread through it. About two-thirds of that vapor escapes into space, but about one-third lands back on the surface of the Moon.The liberated vapor that remains may find its way into “cold traps” near the poles, where craters remain in permanent shadow. Not enough water can be made by the solar wind, the researchers state, meaning that most of it must have already been there since the moon’s formation, or was delivered by impactors:“We know that some of the water must be coming from the Moon, because the mass of water being released is greater than the water mass within the meteoroids coming in,” said the second author of the paper, Dana Hurley of the Johns Hopkins University Applied Physics Laboratory.The analysis indicates that meteoroid impacts release water faster than it can be produced from reactions that occur when the solar wind hits the lunar surface.“The water being lost is likely ancient, either dating back to the formation of the Moon or deposited early in its history,” said Benna.The figure caption says, “in order to sustain the water loss from meteoroid impacts, the hydrated layer requires replenishment from a deeper ancient water reservoir.”In short, the moon is losing its tenuous water faster than it is receiving it or making it. Has this been the case for the moon’s history? Scientists can’t say: “debates continue about the origins of the water, whether it is widely distributed and how much might be present,” the press release said. The infographic caption shows “ancient H2O at depth” percolating upward as a “hypothetical” process, but the only water with empirical support comes from the “hydrated layer” more than 3 inches below the surface. So, “in order to sustain the water loss from meteoroid impacts, the hydrated layer requires replenishment from a deeper ancient water reservoir” that is only theoretical.This situation is analogous to Titan’s methane loss. Determined to keep Titan billions of years old, planetary scientists have had to imagine an unobservable methane reservoir locked up below the surface that burps out into the atmosphere from time to time. Scientists should clearly state their assumptions as assumptions, not as the only reasonable options. If the moon only has a shallow hydrated layer, the moyboys are in big trouble.The Flood model by Walt Brown (the Hydroplate Theory) postulates that supercritical water shot out from the fountains of the great deep (Genesis 7:11) and showered the moon with water molecules. Other escaping water became comets and asteroids. Counter-intuitive as it may seem, only a small fraction of the escaping water from the subterranean chambers that form the basis of his theory would have been needed to supply these water sources in space. If interested, you can read his supporting arguments for these processes at his website.Whatever one’s beliefs, a plausible theory is required to explain the origin of the moon’s water. Secular materialists imagine a wet asteroid coming in and striking the Earth, creating a debris disk that formed the moon. That theory has numerous problems, from the improbability of a source impactor, the improbability of a Goldilocks strike, the improbability of any volatiles remaining behind, and a means to get the water to the surface. Brown’s model provides a rigorous attempt to explain all the observations. Let other models match that level of detail. In any event, the case of the moon’s water loss over time calls into question the billions-of-years story for the moon. Here’s an opportunity for non-moyboys to contribute to the debate.(Visited 343 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

The Cutting Edge of Smart Cards: Japan’s Suica Card

first_imgRelated Posts Image credits: purprin; jpellgen; David Murakami Wood 8 Best WordPress Hosting Solutions on the Market richard macmanus Tags:#Internet of Things#Product Reviews#web Why Tech Companies Need Simpler Terms of Servic… This week we’re looking at the world of Smart Cards. Yesterday we checked out the Oyster Card, an RFID-powered smart card that millions of Londoners are using to pay for public transport. It’s one of the largest implementations of RFID in the western world. However perhaps because of that scale, it’s also fairly conservative. Right now the Oyster Card is only used on public transport and there is little Internet functionality available. We can find a more cutting edge example of smart cards in, where else, Japan. The Suica card – produced by transport company JR East (East Japan Railway Company) – is used on most trains, subways and buses in the Greater Tokyo, Sendai and Niigata regions. It is also used in a variety of micro-payment scenarios. The main function of the Suica card is payment for train and bus rides. However the card is increasingly being used to make purchases at stores and kiosks within the train stations, as well as in airport stores and taxis. The card is also available as an option at some Japanese e-commerce stores. As of April 2009, over 28 million Suica cards were in circulation. Many people have more than one Suica card, so this number doesn’t equate to the amount of users. Suica stands for “Super Urban Intelligent Card.” Like the Oyster card, the Suica card uses RFID technology. Also noteworthy is that the Suica isn’t the only smart card option for Japan’s rail system – the Pasmo card is another popular one.There is a Mobile Suica, enabling Osaifu Keitai mobile phone users to use Suica via their phone instead of a card.There have been mashups made with Suica data. An example is Sherelog, a service that fetches data from Suica and “visualizes personal train-ride records on a large public map (or Google Map).”Suica Posters Connect to Net – But Note The Privacy Warnings Probably the best example of Internet applications built using Suica has been the ‘SuiPo’ (short for ‘Suica Poster’) sites. These are Suica-enabled advertising posters that, when scanned with a Suica card or phone, send further details to your email. As with anything RFID-related, there are privacy and security concerns. Surveillance expert David Murakami Wood says that while SuiPo are activated by consumers (and so are opt-in), they could also “lead to the accumulation of a lot of data on consumption interests.” He warns that this “potentially generates a massive consumer surveillance tool, because it can be linked up [to] travel patterns.” Wood helpfully translated the SuiPo webpage on privacy and data protection. He summarizes what Suica can do with user data as follows: 1. Sending the specific requested information to you;2. Improving services; 3. Data processing and analysis; 4. JR East’s promotional marketing; and 5. JR East customer questionnaires. Wood wryly notes that “Purposes 2 and 3 pretty much allow JR [East] to do anything it likes with the data.” ConclusionAs usual Japan is a number of years ahead of western countries in mobile technology. But hopefully this type of functionality on smart cards won’t be too far away in the U.S. and the rest of the world.To conclude, we recommend you watch these cute Japanese ads to see the full range of uses for Suica: A Web Developer’s New Best Friend is the AI Wai… Top Reasons to Go With Managed WordPress Hostinglast_img read more

Google Rolls Out New Format for Image Results

first_imgAccording to an announcement on the Official Google Blog, the search engine giant is rolling out a new format for their universal image results. Set to go live over the next 24 hours, the updated format will now feature one larger image alongside multiple smaller images. Because of this new layout, you’ll be able to see “more pictures than before,” writes Google Software Engineer Alex Petcherski in the blog post. The New Image ResultsTo be clear, this update is for universal image results only – not Google Image search itself. “Universal” results refer to the search results you receive when doing a traditional search on Introduced back in 2007, the term refers to the combined search results from multiple verticals, including image search, news, video search, and the other specialized engines linked from the top of Google’s homepage. With universal search, you only have to refer to one set search results page to see all the relevant information on a particular topic. The page serves as the jumping off point for whatever knowledge you’re after – whether that’s a photo, a video, the latest news, or just good ol’ fashioned information. 8 Best WordPress Hosting Solutions on the Market The updated image search results represent a minor change to Google’s interface and one that many mainstream users may not have even noticed. But every little tweak that Google makes is only done after extensive testing. In this case, the update allows for one more image to appear in the universal image results box. One image may not seem like a major improvement, but it could mean the difference between a user clicking through to see more or abandoning their Google Search altogether. (You would be surprised how quickly some users give up on a non-productive search. Forget refining queries, they just go elsewhere or stop their search entirely!). Google Announcement’s Timing Aimed to Deflate Interest in BingIt’s also notable that Google is announcing this change around the same time as Microsoft plans to make another announcement regarding updated features for Bing, the company’s new search engine. Since its launch earlier this year, the Bing Search Team at Microsoft has been busy rolling out updates that have included things like a revamped mobile search, improvements to maps, integration with math engine Wolfram Alpha, Twitter integration, and a new visual search interface. As most of these announcements were made, Google would make an announcement of their own – for example, how they were planning on adding Twitter to their results, too. And when Bing announced Visual Search, Google posted to their blog about a Google Experiment called “Fast Flip” which lets you visually peruse print articles online. There’s no doubt that the timing of this latest, albeit minor, news about Image Search improvements has to do at least partially with the upcoming Bing announcement. Clearly, we have entered a new era of “search wars.” As angel investor Ron Conway noted earlier this fall at the TC50 conference, this time war is a good thing: “I think the huge winner here will be consumers because competition breeds innovation, and this nice little battle between Google and Microsoft is fantastic for consumers.”Disclosure: Sarah Perez also freelances for Microsoft’s Channel 10.

Insulating a New House

first_imgAn owner-builder planning a new home in southern Ontario isn’t looking for a net-zero house, just one that’s well insulated and protected from moisture problems. The question is whether his proposed wall system is his best option.“I’m unwilling to put foam board on the outside and vapor barrier on the inside,” writes User 6782048, whom we’ll just call Ontario, in a question posted on our Q&A page. “Just seems wrong.”He does plan on some exterior foam — a 1-inch-thick layer over the studs, followed by plywood and then Tyvek housewrap. After rough wiring, the 2×6 wall cavities would get a 2-inch layer of closed-cell foam and then batt insulation.The technique of combining spray foam with batt insulation is called “flash and batt”, and Ontario believes the total of 3 inches of foam would keep the exterior sheathing above the dew point in winter, thus reducing the chance of moisture condensation inside the walls.“Thoughts, please!” Ontario writes. That’s the topic for this Q&A Spotlight. The downside of flash-and-battFilling a stud cavity with closed-cell foam provides an excellent air seal, but it’s expensive — and that’s why some builders advocate the flash-and-batt approach. But, writes Andy Chappell-Dick, it’s still costly, “it relies on the least ‘green’ insulation, and it’s interrupted (and thus substantially degraded) every 16 inches by a stud.”The technique may be useful in tightening up an old house in an efficiency-inspired renovation, but for new construction it would be better to put all of the foam on the exterior of the house. Further, Chappell-Dick adds, it would be wise to substitute a smart permeable vapor retarder for a polyethylene vapor barrier on the warm side of the wall.Another problem with Ontario’s proposed wall is that 1 inch of exterior foam doesn’t offer much protection against thermal bridging, while the assembly would require unnecessary time and money.“Seems like a lot of work (wind bracing) and money (spray foam) for a slightly above average wall,” writes Rick Evans, suggesting the proposed wall would have an R-value of just over 28. “Using spray foam to gain an extra R-3.5 or so probably has a long payback period from an environmental standpoint as well. (How many BTUs are you really saving with that?)“I suspect you could add 3 inches of exterior rigid foam (Type II or higher EPS) over the 2×6 studs and sheathing for the same cost as the enclosure that you described,” Evans continues. “This would give you an R-33 wall with better protection from thermal bridging. From a moisture standpoint, this wall is at least as safe as the one you are considering, so long as you lose the interior vapor barrier. (Obviously, be sure to add an air gap under the siding in both enclosures.) If code requires a vapor barrier, then slice open the poly once the inspector leaves or opt for a smart vapor barrier like MemBrain or Intello Plus.” Resistance on exterior foamThree inches of foam on the exterior of the building no doubt would be better from a thermal point of view, replies Ontario, but that’s not going to happen.“I agree totally that the 3 inches of foam on the outside would give better insulation results,” Ontario writes. “It’s the added time and costs that I’m trying to avoid, such as 6-inch screws to attach strapping, boxes to house windows, installation of the foam itself, self-supporting decks. By no means am I trying to go net-zero or near. Just a well insulated house without moisture problems.”The thickest layer of foam Ontario would consider is 1 1/2 inches, although the 1-inch layer he has proposed is more attractive.And as to the cost of the spray foam, Ontario will be getting that at cost, courtesy of a friend for whom he’s done work in the past.An option suggested by Anthony Mach is to use Roxul ComfortBoard insulated sheathing, available in several thicknesses with corresponding R-values up to an R-12 panel 3 inches thick. “It’s permeable, fireproof and soundproof,” he says. “I’m in Ontario and it’s code-compliant.”Or, adds Dana Dorsett, use rigid polyisocyanurate foam instead. “At the same wall thickness you can get higher performance at a lower cost out of 2 inches of exterior polyiso held in place by 1×4 furring through-screwed to 2×4 framing with 5-inch pancake head timber screws 24 inches on-center, R-13 or R-15 batts in the stud bays, with the siding mounted to the furring,” Dorsett writes.“The plywood layer can be between the foam and studs, and fully structural,” he continues. “Your proposed stackup has the plywood out in the cold, where it it is subjected to exterior moisture drives (and would need to be rain-screened, not just housewrapped) to be reasonably well protected. The 2×4/R-13 + 2 inches polyiso solution comes in at slightly higher thermal performance, and in a southern Ontario climate it would not accumulate moisture over the winter, even using just standard latex paint on gyprock as the vapor retarder (though you may need to install a 2-mil nylon ‘smart’ vapor retarder such as MemBrain to convince the inspectors.)” RELATED ARTICLES Too much of a hassleBuilding exterior walls with 2x4s, one option suggested by Dorsett, would make it harder to place roof trusses, Ontario says, because the top plate is that much narrower. And as for a rainscreen, well, that’s probably not going to happen.“I have resided houses 30+ years old with no housewrap and the plywood has shown no sign of moisture damage,” Ontario writes. “If you side correctly, no rainscreen is required. As for the environmental issue [of using spray foam insulation], I’ll not comment unless you live in a straw bale home. We are all just as guilty. It’s ridiculous [that] people bring it up, like rigid foam is a natural resource and not produced in a factory. LOL.”The exchange prompts this reply from Andrew C: “If you come to a website with the name Green Building Advisor and ask for input, you shouldn’t be surprised if some of the advice is about how to make a house ‘greener,’ in addition to more comfortable, efficient, durable, etc. If you have different views, you’re free to ignore comments, but you’re not likely to encourage people to share their valuable experience and knowledge if you slam the door in their faces.“Your personal experience in working on old houses may be pertinent to a new build with different materials and different levels of air-sealing and insulation than were common in the past,” Andrew C continues. “Maybe not. If the majority of experts now recommend rainscreens for most siding applications, perhaps you should consider it.”Not at all, says Ontario.“I came to a website and got some good information, but never really got my question about moisture answered!” Ontario says. “I don’t feel I slammed the door, but got the door slammed on me. It seems most people want to plug their own ideas without any regard for other ideas. The exterior Roxul batts was the only idea that even remotely took my thoughts into context. Sorry not everyone agrees with yours or others thoughts, but some of us look at it from a building standpoint. Time and pressure. Maybe something you fail to comprehend. Lucky you!”In response, GBA senior editor Martin Holladay writes, “Here is the answer: Your house is located in Climate Zone 6. If you intend to install rigid foam on the exterior side of your wall sheathing, and if you want to avoid moisture problems in your 2×6 walls, then the minimum R-value of the rigid foam is R-11.25 (assuming, that is, that the stud bays are filled with a fluffy insulation product like fiberglass).If you install only 1 inch of rigid foam (about R-4 to R-6, depending on the foam type selected), you risk moisture accumulation in your stud bays. To learn more, read this article: Calculating the Minimum Thickness of Rigid Foam Sheathing.”center_img Flash-and-Batt InsulationThe Flash-and-Batt Method Calculating the Minimum Thickness of Rigid Foam Insulation Can Exterior Foam Insulation Cause Mold and Moisture Problems?Combining Exterior Rigid Foam With Fluffy InsulationThe Exterior Rigid Foam is Too Thin! Installing Mineral Wool Insulation Over Exterior Wall Sheathing Installing Closed-Cell Foam Between Studs is a WasteHow to Design a Wall (For more on how to change a user name from a number to a real name, a quirk in GBA’s registration process, follow this link.) Our expert’s opinionPeter Yost, GBA’s technical director, adds these thoughts:If you specify a vapor-permeable water-resistive barrier (WRB), putting your structural sheathing to the exterior of your rigid insulation does give the sheathing good drying potential. While you are using plywood, the assembly you describe is a lot like Zip System R sheathing. Of course, the type of sheathing fasteners and fastening schedule are important when you place rigid insulation between the sheathing and your framing. With one inch of rigid insulation, that’s pretty straightforward; it gets increasingly difficult as you move to greater thicknesses of rigid foam.The moisture performance of your proposed flash-and-batt system depends on the R-value of the components, the indoor relative humidity, and your climate. Here are the assumptions I am making about your wall assembly and environment:1 inch of rigid insulation: R-5.2 inches of closed-cell spray foam: R-12.3 1/2 inches of fiberglass batt insulation: R-13.Outdoor average wintertime temperature for the three coldest months in Ontario: 23°F.Indoor temperature average in your home for winter: 68°F.Indoor relative humidity for the same period: 40%.A quick dew point calculation indicates that your first condensing surface temperature (the inside face of your spray foam) would average 49°F, well above the dew point for your interior air of 43°F.This suggests that only a Class III vapor retarder (1 to 10 perms) would be needed for your assembly to maintain good moisture performance of your wall assembly. Would a smart vapor retarder be a good idea? Yes. It would further improve the moisture performance of your wall assembly. Would polyethylene sheeting (a Class I vapor retarder) be a good idea? No, it would reduce the drying potential to the interior unnecessarily.Finally, the most important moisture performance of your assembly — given that you are already aware of and committed to a good WRB and a good flashing system to manage bulk water — is your continuous air barrier. Despite the great air seal of your cavity spray foam, I would be detailing the housewrap, the plywood sheathing, or the rigid insulation to act as a continuous exterior air barrier.last_img read more

Sandhya wins silver and helps lift the gloom

first_imgFull credit to Sandhyarani Devi Wangkhem for ensuring India won at least one medal on Wednesday as the Manipur girl clinched a silver in wushu.This edition of the Asian Games has been one of huge disappointments and surprises for India. If the shooters and weightlifters have performed miserably, swimming, gymnastics and now a Chinese martial art have partially lifted the gloom.Having sustained an injury in the semi-finals, Sandhyarani fought bravely against her Iranian rival Khadijeh Azadpour in the final before losing on points. As the defending champion, Khadijeh used her experience to good effect against the Indian at the Nansha Gymnasium where the number of Indians present in the hall was indeed surprising.To be sure, Sandhyarani has never seen this kind of support for her, though from a medal point of view, her feat needs to be lauded. That she was not fully fit could be gauged from the fact that the Indian could not kick well. Khadijeh apparently knew her rival’s injury and knew where to attack. “I was trying to use my arms but that did not work,” Sandhyarani said.From the start, Khadijeh was aggressive as she twice pushed the Indian out of the zone on the floor. The tall Iranian was indeed quick on her feet and used her height to good advantage.As the contest progressed, Sandhyarani, who is a CRPF officer, tried using defensive tactics, but it did not work. “I am sad not to have won gold. I was hoping for the best but my calf injury prevented me from giving my best,” said Sandhyarani.advertisementAnother problem for the Indian was that she had to change her weight category. “I compete in the 56kg category. Since that category was not listed in the competition I entered in the 60kg,” said the Indian. Her bodyweight now is 59kg at a height of five feet four inches. “If only I had won gold it would have been very good,” lamented Sandhyarani.Wushu was introduced as a medal sport at the Asian Games in Beijing in 1990. There are many forms of this martial art which has its roots in China. The forms comprise basic movements like stances, kicks, punches, jumps, sweeps and throws.In the Asian Games, ‘sanshou’ is the name given to the form of wushu where speed, alertness and reflexes matter. However, for an Indian to win silver in the event is indeed a welcome surprise.last_img read more
