15 December 2005Four years after finishing their race, South Africa’s mens’ 4x100m relay team have been declared world champions.Competing at the 2001 IAAF World Championships in Edmonton, Canada, the team finished second to the favourites from the US. The South Africans, Morne Nagel, Corne du Plessis, Lee-Roy Newton and Matthew Quinn, ran the races of their lives to reach the finals and finish second to the Americans.Their time of 38.47 sec is the current South African record.Prohibited substanceTim Montgomery, a member of the 2001 US relay team, was on Tuesday found guilty of a doping offence.Although Montgomery has never tested positive for any IAAF-prohibited substances, he was convicted after testimony by other athletes that he admitted to using a substance he called “clear”.Montgomery declined to give evidence in his defence.He announced his retirement from athletics following the Council of Arbitration for Sport’s decision to impose a two-year ban.Retroactive cancellationThe two-year suspension also includes a retroactive cancellation of all his performances dating back to 31 March 2005. This means that all the times that Montgomery ran, including his 2002 world record, and all his results and wins, have been removed from the record books.The cancellation disqualifies the American team’s 2001 World Championships victory, and hands the South Africans the gold.Ironically, the Americans only made the 2001 final after appealling their semi-final disqualification for a lane infringement.The South Africans now become one of the very few teams to have won the short relay, as the Americans have had a virtual stranglehold on the event. Only the Canadian and Trinidadian teams have challenged the American supremacy in the event.The South Africans said at the time that Hestrie Cloete’s gold in the Women’s high jump, won minutes earlier, had pumped them up.SouthAfrica.info reporter Want to use this article in your publication or on your website?See: Using SAinfo material
Share Facebook Twitter Google + LinkedIn Pinterest Over the next several weeks the upper canopy in Ohio corn fields will look much different, as tassels begin to emerge and extend beyond the top leaves of the plant. This visual change signifies that the corn crop will soon be shifting from vegetative into reproductive growth. The first reproductive growth stage (R1) begins when silks extends outside of the husk leaves and typically occurs two to three days after tassel emergence.The two basic processes that occur during corn reproduction are pollination (transfer of pollen grains from the tassel to the silks) and fertilization (joining of the pollen grain and ovary to create an embryo). Though these processes seem very simple, there is a lot riding on their success. Approximately 85% of the variability in grain yield is related to the number of kernels produced per acre while the remaining 15% of the variability in grain yield is related to the weight of these kernels. Thus, failure in either of these reproductive steps can have a detrimental effect on yield.The most stress-susceptible period in corn is about one week prior to silking and continues for two weeks after silking. The timing of the stress can result in dramatic differences from one field to the next. A very small variation of even just a day or two difference in flowering date or planting date can cause a substantial effect in the success of pollination and kernel set. Water stress is the most common stress factor in corn, although high temperatures and loss of leaf area — from hail, diseases, insects, etc. — can also reduce yield during this critical time especially when coupled with drought stress.Severe drought any time during plant development can have a negative effect on yield potential, but the greatest impact is when drought stress occurs during the pollination and early grain-fill stages. Research at Iowa State University has shown that yields can be reduced by as much as 40 to 50% when corn undergoes four consecutive days of severe stress during the pollination phase. Moisture stress that occurs during the vegetative growth stages or during later grain fill has much less effect on yield. Stress effects from drought that takes place from one week prior to tasseling through the milk stage causes lack of ovule fertilization or kernel abortion. Moisture stress that occurs from the dough stage to black layer will lead to reduced kernel weight.The greatest risk of kernel reduction at pollination is the asynchrony of pollen shed and silking. Drought stress tends to accelerate pollen shed while delaying silk growth, which can result in poor “nick” of the pollen and silks. A single plant will shed pollen for only about five days but because of natural field variability in plant development a whole field may take up to 14 days to complete pollen shed. Silks begin elongating from the ovules of the ear shoot about seven days prior to emerging from the ear shoot. Silk growth occurs by cell expansion, so if a plant lacks the necessary water than silk development will be slowed or halted. Silks that emerge after most of the pollen is shed will not likely be pollinated. Moderate silk delay can cause poorly-filled ear tips, whereas more severe stress can result in ears that are nearly or completely barren.Corn maximizes its growth rate at 86 degrees F during the day and 60 to 65 degrees F at night. When daytime temperatures reach into the 90s, then plant stress results. High daytime temperatures decrease photosynthesis efficiency, which causes the plant to make less sugar that will in turn be used to produce plant biomass and grain. High night temperatures on the other hand can be even more detrimental to corn than high daytime temperatures. Elevated nighttime temperatures increase the respiration rate, causing the plant to spend more energy for the maintenance — energy that could have otherwise been used in dry matter accumulation. The respiration rate of plants increases rapidly as the temperature increases, approximately doubling for each 13 degree F increase. With high night temperatures more of the sugars produced by photosynthesis during the day are lost, which leave less available to fill developing kernels. High nighttime temperatures also result in a shortened grain fill period that will limit the time the crop has to add additional starch to the kernels.Curious to know how successful your corn fields were at pollinating? Follow the steps below and find out.1. Remove the ear from the plant.2. Gently peel the husks from the ear so that the silks are disturbed as little as possible.3. Grab the ear by the base and hold the ear so that the tip is pointing toward the ground.4. Gently shake the ear. Silks will fall from fertilized ovules, while silks of ovules not fertilized will remain attached to the developing ovules.5. Percent pollination is equal to the percent of ovules with no silks attached.

Liverpool star Salah ‘must rest’ insists Egypt coach El Badryby Freddie Taylor21 days agoSend to a friendShare the loveEgypt coach Hossam El Badry believes that his star player Mohamed Salah needs rest.The Liverpool winger is set to miss the nation’s friendly against Botswana during the upcoming international period.And El Badry knows he must take the long term health of the player into consideration when deciding on his line up.”I agreed with him that it is in his best interests and those of the national team that he rests,” El Badry told local channel MBC Masr.”He won’t be with us at the training camp for Botswana, but God willing, he will be with us for the official matches.” About the authorFreddie TaylorShare the loveHave your say
NORDEGG, Alta. – This is a story about one lucky loon.Don Gibson was standing with his family on a dock in Fish Lake Provincial Park west-central Alberta last weekend when he noticed a normally standoffish loon — one of a group of five that call the lake home — swimming toward them.“I said, ‘There’s no way that’s a real loon because they don’t come that close,’” Gibson recalled Friday from his home in Sundre, northwest of Calgary.“I said, ‘Somebody’s out in the woods playing a trick on us. They’ve got a remote-control bird or something.’”But as the loon got closer, Gibson could tell it needed help.A piece of fishing gear with wire leaders and multiple hooks, often referred to as a pickerel rig, had become tangled around the bird’s bill, neck and leg.Loons are sleek and rely on their diving ability to catch fish, frogs and other water creatures. Seeing the way this one was tangled, it was clear to Gibson that it couldn’t hunt.The bird kept looking up at the campers on the dock and moved to a shallow area along the shore.“This one just knew he only had another day and he was going to die. He was just right pooped I think.”Gibson turned to his 12-year-old son.“I said, ‘We’ve got to go over there. This thing just sent us a sign that he’s in distress and he wants us to help him.’”Gibson was leery about the loon’s sharp beak, but the bird lowered its head and allowed him to give it a stroke.“When he allowed me to pat his head, I said, ‘That’s it. I am taking my shoes off and I’m going in and I am going to help this guy, because he was obviously not afraid of me.’”Gibson’s wife enlisted the help of a park attendant who had some scissors and they started cutting away the tackle. A hook caught in the back of the bird’s neck came out easily. Gibson then picked up the bird and unwound the line that was wrapped three or four times around its leg.By then, a fairly large crowd had gathered to watch the rescue.Gibson put the freed bird back in the water.As it swam out from shore to rejoin its buddies, it turned back, lifted itself up in the water and gave a flap of its wings as if to say thank you, he said.Everyone cheered.“You couldn’t write a fiction novel so perfect.”Gibson said he saw the five loons feeding on minnows in the lake the next day, so he figures everything worked out fine.“I wouldn’t believe it if I didn’t see it myself. He knew exactly what he was doing. It was incredible.”
MONTREAL – In a sun-lit lecture space at Ecole Polytechnique, Joelle Pineau explained how a machine can create a recipe from a photo of a tourtiere.It’s not easy as pie, but rather the fruit of 12 months of experimentation at Facebook’s new artificial intelligence lab, which she heads up in Montreal.“I would like the robot that goes with it and then makes the recipe,” joked Pineau, an associate professor at McGill University.Facebook’s lab has already expanded to 20 specialists from four since its launch in September 2017, with plans to move to a bigger facility come January. Microsoft Corp. and Google parent Alphabet Inc. have both launched Montreal-based AI labs in the past two years, and aim to hire scores more researchers in the next year or so.It’s not just Montreal’s AI sector that’s booming. A mix of cutting-edge tech clusters, real estate growth and old mainstays like tourism and shipping are transforming the city into an economic hot spot after decades of battling a frosty business image.Regional gross domestic product grew 3.5 per cent in 2017, according to Statistics Canada, outpacing Toronto and Vancouver as Montreal enjoyed its biggest growth spurt in more than 10 years. Unemployment has hovered at around six per cent for the past 12 months, remaining near all-time lows.Meanwhile, foreign direct investment surpassed $2 billion in 2017, a new record that marks a 50 per cent increase over 2016 and a 100 per cent jump from 2015.“There’s definitely a buzz around Montreal, especially the high-tech sectors,” said Christian Bernard, chief economist with Montreal International, an economic development agency.Up to 75 per cent of foreign direct investment last year went toward high-tech sectors such as gaming, visual effects and aerospace as well as life sciences and health technology, he said.“The technology is very broad, and the talent can move around from one area to another, one niche application to another,” said Universite de Montreal computer scientist and deep-learning pioneer Yoshua Bengio, who serves as scientific director of the new Montreal Institute for Learning Algorithms.Bengio cited as a key catalyst French gaming company Ubisoft Entertainment SA, which opened a small office in Montreal in 1997 that now employs 3,500 workers.Cash has been pouring into Montreal from public and private institutions, including more than $300 million over the next five years from the federal and provincial governments to bankroll big data research at Montreal universities and foster a regional AI “super-cluster”.Brad Henderson, chief executive of Sotheby’s International Realty Canada, said mortgage stress tests and higher interest rates haven’t dampened Montreal’s real estate market, which he called the healthiest in Canada.The city’s $1 million-plus real estate sales increased 19 per cent year over year in July and August, and they’re poised “to set new records to the end of 2018,” according to a Sotheby’s report in September.Quebec’ political situation has calmed investor fears, he added.“Montreal’s always kind of had a bit of a political overhang,” Henderson said, “but the concerns about separatism have largely dissipated, and that in our opinion has contributed to the steady growth that we’ve seen in Montreal.”Montreal’s port continues to underpin the regional economy, as the year-old free-trade deal between Canada and the European Union boosts container shipping and prompts a hiring spree at the docks, according to port officials.Container imports increased 7.8 per cent to nearly 4.33 million tonnes in the first seven months of this year compared with the same period in 2017, with the bulk of that traffic coming from Europe.Tourism is also on the rise, with Trudeau International Airport welcoming more than 11 million foreign passengers in the first eight months of 2018 for a 6.9 per cent year-over-year gain, according to Tourisme Montreal.However, the same features Montrealers cite as strengths can detract from the city’s sheen as well.In 2016, median household incomes in Montreal climbed more quickly than in many metropolitan areas, but they remained among the lowest of any major city in Canada at $61,790, according to StatCan figures.High employment points to a severe thirst for a bigger talent pool, said Montreal Board of Trade president Michel Leblanc.Many parts of the province are now “beyond full employment,” with a demand for more qualified workers in sectors ranging from hospitality to transportation to the tech scene, Leblanc said.“We need to have more immigrants,” he said, one day before Quebeckers voted the Coalition Avenir Quebec to power on Oct. 1, whose leader Francois Legault has pledged to reduce immigration by 20 per cent.One-third of Quebec’s workforce will have to be replaced in the next 10 years as the population ages, said Mia Homsy, director of the Institut du Quebec, a public policy think tank.“It’s already starting to affect investments and production, with a direct impact on GDP,” she said.Population growth in the Montreal census metropolitan area has been relatively slow, rising 11 per cent to 4.1 million residents between 2007 and 2017, according to StatCan. The rate lags well behind Canada’s five other biggest urban areas.Despite its rapid growth, Montreal’s affordability is better than many of the other 10 biggest cities on the continent, said Loic Jegousse, head of cyber and IT risk with a BNP Paribas team that launched in Montreal last May.“I myself have two teenage daughters. I used to live in Toronto, and I thought it would be wise to come to Montreal so they can actually afford a home when they grow up,” he said.“Montreal was very sleepy for a long, long time, but now it is going through a renaissance.”
New York Yankees all-time great Bernie Williams is teaming up with Boehringer Ingelheim to raise awareness of a lung disease called idiopathic pulmonary fibrosis (IPF) that his father suffered from for years before he passed away in 2001.Back in Puerto Rico, Williams’ father Bernabé inspired him to play baseball and make it to the Major Leagues. He also taught him to play guitar, which has become Williams’ second career since retiring from baseball.In honor of his father’s battle with IPF, Williams has joined the Sin Aliento campaign to turn his family’s devastating experience with this rare lung disease into a chance to help other families. Williams hopes to educate and empower others who think they may have IPF to seek early diagnosis and treatment and is encouraging people to visit the campaign website www.SinAliento.com – and share the videos and educational Spanish content through social media channels such as Facebook and Twitter using #SinAliento. In addition, they can sign up to the Sin Aliento™ program and receive monthly information in Spanish via e-mail or text messages.“Whether I was in centerfield or at bat, my dad was always my biggest fan. He seemed invincible. So when he was finally diagnosed with IPF after battling symptoms like breathlessness and a debilitating cough that persisted for many months, it was devastating to me and my family,” said Williams. “Sharing my dad’s story is so important because it will help others get the answers they need sooner and easier.”IPF is a rare and serious lung disease that causes permanent scarring of the lungs, and makes it difficult to breathe. Symptoms of IPF include breathlessness during activity, a dry and persistent cough, chest discomfort, fatigue and weakness. Although considered “rare,” IPF affects up to 132,000 Americans, and according to the The Lancet, Hispanics are more likely to suffer from the disease with a 15% higher incidence than the general population. Also, about 50,000 people in the U.S. are diagnosed every year with IPF – enough to fill a baseball stadium.“Boehringer Ingelheim is proud to partner with baseball legend Bernie Williams who can speak personally about how IPF affected his dad and his family,” said Al Masucci, vice president, IPF Business Unit, Boehringer Ingelheim Pharmaceuticals, Inc. “Through the Sin Aliento campaign, we hope to educate people to recognize the signs of the disease and take action to see a doctor as early as possible. It is important that a correct medical diagnosis is determined as IPF is often misdiagnosed.”The symptoms of IPF are similar to, and often confused with, other more recognizable diseases such chronic obstructive pulmonary disease (COPD), asthma, or congestive heart failure. There are IPF treatments available, including supplemental oxygen, cough management and pulmonary rehabilitation, which can include special exercises or breathing strategies. In 2014, the U.S. Food and Drug Administration (FDA) approved the first drugs specifically indicated for the treatment of IPF.
Jamui (Bihar): Prime Minister Narendra Modi Tuesday launched a scathing attack on the Congress, saying governance goes into reverse gear when the grand old party and its allies are in power. Addressing an election rally in Jamui where LJP leader Chirag Paswan, son of party president Ram Vilas Paswan, is in the fray, Modi accused the Congress of having neglected B R Ambedkar like no other party did. He also claimed that his rivals were spreading the canard that the BJP, if voted to power again, will do away with reservations for the backward classes.

Terrorism, prices, violence, corruption, black money rise when Congress is in power; the country’s prosperity, its credibility, the morale of the armed forces, respect for honesty decline,” he said. He accused the Congress of having done everything to “defeat” Ambedkar, the architect of the Indian Constitution. “The Congress did everything possible to have Babasaheb defeated. It conspired to have his momory erased from the public mind. The ‘family’ remembered honouring its own members with Bharat Ratna but forgot Ambedkar,” the prime minister said.

Claiming that his detractors were spreading the rumour that the BJP will do away with quotas in government jobs and educational institutions if voted to power again, Modi declared, “Nobody can even touch reservations for the backward classes.” “We introduced 10 per cent quota for the economically backward people among the unreserved category…we did it without causing strife in society,” he said.
