JC drub Clan Carthy

first_imgBilled as champions versus football minnows, title holders Jamaica College (JC) showed no mercy with Clan Carthy High, as they controlled, and bossed the game from start to finish, and strode to an easy 4-0 win in their ISSA/FLOW Manning Cup match, at the Jamaica College football field on Old Hope Road, yesterday.Leading forward Ronaldo Brown stepped up with a brace in the 24th and 86th minutes.Brown’s double puts him at three, so far, and he looks set to go past 20 for the season.Prior to that, Khori Edmond sent JC ahead in the 22nd minute. Captain Allando Brown proved his reliability and versatility as a centre back to head home their third goal in the 27th minute.”It is an amazing feeling to score two goals today,” Brown said, while noting that he idolises Junior Flemmings, who led JC’s scoring charge last season.”I idolise Flemmings, and coach has called on me to step up and get goals like he did for our school. We are a championship team, and I am trying to build my legacy without being under pressure of living up to his name,” (Flemmings’) Brown assured.The start of the game was delayed for close to an hour due to rain, but the home still went at their rivals from the first whistle.Coach Miguel Coley said: “We were happy that we could win the game with a clean sheet. The killer instinct is not there yet, but that’s something that we have to instil. When you get teams like this, you want as many goals as possible; 10 if possible,” he told The Gleaner.”Going forward, we are looking better and better, and that will be good for us,” he continued, adding “we have a good team, just that the killer instinct needs to be there.”Meanwhile, Clan Carthy coach Mallawe Blake said his players didn’t follow instructions.”We had chalkboard work at school and we knew that we couldn’t give JC too much space to play but the game just went away from us.”We just have to regroup and face St Catherine at home on Friday,” he assessed.YESTERDAY’S RESULTSGroup AJamaica College 4, Clan Carthy 0Calabar 4, Tivoli 0Group DHoly Trinity 1, Charlie Smith 2St Mary’s College 3, Penwood 1Group EWolmer’s 2, Bridgeport 0St Jago 8, Kingston High 1Group GKingston College 6 Campion 0Camperdown 2, JosÈ MartÌ 0TODAY’S GAMESPapine vs DunoonHydel vs CumberlandGreater Portmore vs Haile SelassieKingston Technical vs ElthamInnswood vs St George’s CollegeArdenne vs Denham TownAscot vs Spanish TownJonathan Grant vs ExcelsiorNorman Manley vs Vauxhalllast_img read more

Plants Use the Perfect Propeller

first_imgWhat kid hasn’t played with maple seeds to watch them spin in the air like helicopters?  Scientists watch them, too.  A team from the Netherlands and California found out how they stay in the air for so long without engines to drive them.  One would think in an era of advanced aeronautical engineering the physics would all be worked out, but the abstract explains that the seeds know more than the engineers do:As they descend, the autorotating seeds of maples and some other trees generate unexpectedly high lift, but how they attain this elevated performance is unknown.  To elucidate the mechanisms responsible, we measured the three-dimensional flow around dynamically scaled models of maple and hornbeam seeds.  Our results indicate that these seeds attain high lift by generating a stable leading-edge vortex (LEV) as they descend.  The compact LEV, which we verified on real specimens, allows maple seeds to remain in the air more effectively than do a variety of nonautorotating seeds. The trees involved often grow in nutrient-poor environments, so their seeds rely on wind, updrafts and turbulent gusts to spread out.  They can sometimes fly several kilometers away from the parent tree.    The team studied three species of maple and one species of hornbeam, because “The seeds from all four of these species are known to generate high lift.”  The seeds start rotating within a meter of detachment.  “They autorotate because the heavy nut, and hence the center of gravity, is located at the base of the wing-shaped seed, they said, emphasizing again how this is partly mysterious: “The stable autorotation of maple and other rotary seeds depends on an interplay between their three-dimensional (3D) inertial and aerodynamic properties, which is not fully understood.”    Measurements of the seeds in wind tunnels showed that the leading-edge vortex (LEV) is attached at the 25% span location where the sectional lift coefficient is the greatest.  “The stable attachment of the LEV is noteworthy, given that the local angles of attack are well beyond the stall point for conventional aircraft wings and helicopter blades.”  They explain how the stalling that endangers pilots is overcome by the seeds:Like autorotating seeds, insect wings generate very high lift despite operating at angles of attack well above those that will stall conventional aircraft wings and helicopter blades (11) (Fig. 1D).  Instead of stalling, insect wings generate a prominent leading-edge vortex (LEV), which is known to be responsible for elevating both lift and drag.  Building upon these observations, we hypothesized that autorotating seeds create a LEV that enables them to generate high lift at high angles of attack during their descent.The authors believe aircraft engineers should go back to the drawing board.  “The enhanced aerodynamic performance of autorotating seeds could inspire the design of more effective autorotating vehicles.”    As to how this phenomenon arose, the scientists noted that a similar LEV lift-generating principle is employed in the wings of bats, birds, insects and seeds.  To them, this suggested “that the use of LEVs represents a convergent aerodynamic solution in the evolution of flight performance in both animals and plants.”    For more on Dickinson’s fascinating research on biological flight design, see the 11/20/2006 entry, and especially the 12/08/2003 entry.1.  Lentink, Dickson, Leeuwen, and Dickinson, “Leading-Edge Vortices Elevate Lift of Autorotating Plant Seeds,” Science, 12 June 2009: Vol. 324. no. 5933, pp. 1438-1440, DOI: 10.1126/science.1174196.Everything about this article was wonderful except the evolutionary storytelling, which incited wonder of a different kind (see Brett Miller’s treatment of the Convergence Concoction).  Convergence is not an answer; it’s a sidestep.  What should have falsified evolution is turned into a support for it by the hocus-pocus of employing a miracle word.  Aircraft engineers don’t need miracles, they need real-world physics, inspired by nature’s designs.  Keep the materialistic metaphysics out of it.    A great film on seed dispersal, including stunning images of autorotating seeds, is the Moody Science production Journey of Life.  Take your kids on a walk in the woods where maples grow and play with the seeds.  Make it a teachable moment.  Older kids might want to do a school science project on autorotating seeds.(Visited 31 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

NDP will determine SA’s direction: Zuma

first_img19 February 2013 The National Development Plan (NDP) is a crucial policy-making tool that will help South Africa develop and determine the direction the country takes, President Jacob Zuma said on SABC’s Sunday Live broadcast on the weekend. The NDP is a a blueprint for eliminating poverty and reducing inequality in South Africa by 2030. It seeks to do this by drawing on the energies of the the country’s people, growing an inclusive economy, enhancing the capacity of the state, and promoting leadership and partnerships throughout society. In his 2013 State of the Nation Address last week, Zuma said the NDP had set the ambitious target of creating 11-million jobs by 2030, which will require teamwork to get the economy growing at a rate of more than 5% a year. “There are sectors that we have identified that will create these 11-million jobs by 2030,” Zuma said on Sunday. “These include infrastructure and the tourism sector, among others. These sectors have already created jobs and employed people.” On the issue of land, Zuma said the government was committed to resolving issues around this. This would be done within the ambit of the country’s Constitution. He added that while progress had been slow, compensation for land would be equitable. The matter needed to be looked at “differently”, he said. On the issue of education, Zuma said education had be treated as an essential service. However this definition should not be seen as denying teachers the right to embark on strike action. “We are talking about the importance of education,” he said, adding that education was a key element to the country moving forward and developing. For non-performing municipalities, the government was following up on the non-submission of financial reports. On the issue of councillors who received tenders, Zuma said that some had already been fired, and the government was looking at how it could review the tender system. On the matter of the abuse of women and children, Zuma said that a national response was necessary, adding that the government cannot fight this scourge alone. “We need to work together as a nation, government cannot do it alone. We need to have specialised courts that will be ready to deal with such situations and convict perpetrators speedily.” On talks of a possible Cabinet reshuffle, the President said: “I haven’t said anything on it, I haven’t said whether it will happen or if it will not happen. I have not spoken to anyone about this. I don’t know where people are getting this.” Source: SAnews.gov.zalast_img read more

Vietnam Bans Glyphosate Imports

first_imgShare Facebook Twitter Google + LinkedIn Pinterest By Todd NeeleyDTN Staff ReporterOMAHA (DTN) — Vietnam’s Ministry of Agriculture and Rural Development banned the import of glyphosate on Wednesday after a series of legal defeats for Bayer in U.S. civil lawsuits alleging the weed killer caused cancer.Vietnam Director of Plant Protection Hoang Trung said during a news conference on Wednesday the action was taken because glyphosate affects the environment and is harmful to human health.At the end of March, a California jury awarded $80 million to a man with non-Hodgkin lymphoma who had used glyphosate at an animal refuge for nearly 30 years. Last year, another jury in the state awarded $287 million to a groundskeeper with cancer who used the chemical. In all, there are 11,200 lawsuits aimed at glyphosate.Charla Lord, media communications, corporate engagement and preparedness for Bayer, said Vietnam’s decision is likely to hurt both farmers and consumers.“Unfortunately, today’s decision banning glyphosate will not help to improve food security, safety or sustainability in the country,” she said. “Importantly, Bayer is not aware of any new scientific assessment undertaken by the government of Vietnam on which the decision is based. Reportedly, it was driven by developments in litigation taking place in the United States.“This litigation does not change the overwhelming weight of over four decades of extensive science and the conclusions of regulators worldwide that support the safety of glyphosate-based herbicide products.”Lord said EPA, the European Food Safety Authority, as well as regulatory agencies in Canada, Japan, Australia, Korea, Brazil and other countries, “routinely review all approved pesticide products and have consistently reaffirmed” that glyphosate is not carcinogenic.“We have seen the unfortunate impact of denying farmers access to such an essential tool,” she said.Sri Lanka, for example, imposed a glyphosate ban in 2015. The ban was reversed in 2018 after local farmers became vocal about the economic effects to their businesses.OTHER PRODUCTSIn a news release, the Vietnam government said glyphosate is not needed because there are 54 other “safe” herbicide active ingredients. Glyphosate products already in circulation in Vietnam are not affected by the ban. Vietnam imports the vast majority of its agriculture chemicals from China.“In particular, individual organizations have also actively registered for herbicides containing new-generation active ingredients, which are bio-effective and safe to replace glyphosate,” the Vietnam’s MARD said in a news release.U.S. Secretary of Agriculture Sonny Perdue said the decision will have “devastating impacts” on agricultural production worldwide.“This ban flies in the face of that scientific evidence,” Perdue said in a statement on Thursday.“Vietnam also needs to look at the potential ramifications for its own farmers. In addition to the immediate effect of slowing the development of Vietnamese agricultural production, there’s the very real risk that Vietnam’s farmers will turn to unregulated, illegal chemical products in place of glyphosate.”Agricultural crops genetically engineered to withstand glyphosate have greatly expanded the use of the chemistry since 1996. Glyphosate also is used in forestry, urban, lawn and garden applications. Bayer also had glyphosate in its portfolio before acquiring Monsanto.That broad use has drawn worldwide attention to the herbicide and to its safety.Though glyphosate was developed by Monsanto, it is off-patent and sold by many agriculture companies as one of the most widely used herbicides in the world. It came to market in 1974 under Monsanto’s Roundup label for control of perennial and annual weeds in non-crop and industrial areas. In 2018, California regulators failed in an attempt to label glyphosate products as “known to cause cancer.”In 2015, the International Agency for Research on Cancer, a World Health Organization agency, concluded glyphosate was “probably carcinogenic.”IARC came under fire as a result of its broad declarations about what is carcinogenic in summary reports the IARC calls “monographs.” The agency, for instance, drew scorn in 2015 for a monograph classifying processed red meats such as bacon as carcinogenic.The IARC’s glyphosate finding set off a series of reactions. The EPA released and retracted a report refuting the IARC’s conclusion in 2015.At the end of December 2017, the EPA announced in its draft risk assessment of glyphosate that the herbicide is not likely to be carcinogenic to humans.At the end of November 2017, the European Union approved a five-year extension of glyphosate’s use.Todd Neeley can be reached at todd.neeley@dtn.comFollow him on Twitter @toddneeleyDTN(BAS/AG)© Copyright 2019 DTN/The Progressive Farmer.

Improve Activity or Increase Effectiveness

first_imgLet’s say your sales results are off by 50 percent. You are literally producing half of your number. There are a few things you can do to improve your results and close the gap.First, you can double your activity. You can do twice as much work, which for many people may be exactly what is necessary.Second, you can double your effectiveness. You can double the size of the opportunities and double your win rates. This recipe will also produce an improvement, and it may also be a good choice.The first choice begins with an assumption that sales is strictly a numbers game. In this view, there is nothing but activity. More activity leads to more opportunities leads to more wins, and there is no reason to do anything except double up your prospecting efforts, which, again, may not be a bad idea for those who do too little to create the results they need.Choosing only to increase activity leaves out too many other factors to make it the only thing that one might do—or should do—to improve their sales results.The second choice begins with a different assumption than the idea that activity is the only thing necessary to producing results. Instead, this view is biased toward improving the effectiveness of the sales force or salespeople who are struggling. The training, development, and coaching that increase one’s ability to target their dream clients and create bigger opportunities isn’t easy to provide and it doesn’t produce results as fast as one might hope. But the upside of working on effectiveness is that it also improves win rates, and a higher percentage of wins against bigger opportunities improves results exponentially, almost invariably more than activity alone.The truth of the matter is that some people need more activity to produce the better results they need. Others need to improve their effectiveness to close the gap between their results now and the results they need, especially if they already have good activity.Some, however, need to improve their activity while they work on their effectiveness. The increased activity solves the problem that is low activity, and the additional reps provide them with the opportunity to practice the new mindsets and skills that will—eventually—lead to greater effectiveness.
