Sky’s the limit for McLeod – Graham

first_img PROBLEMS McLeod has recently run 9.99 seconds for the 100 metres, but Graham doesn’t believe the accelerated velocity will create problems. “All he has to do is fix his leg sometimes by not hitting the hurdle,” he suggested. “Once he’s clean, we’re going to see something fantastic soon, before even Rio”, Graham said, using hurdling terminology to describe a race when the athlete isn’t slowed down by contact with any of the 10 obstacles. More broadly, the experienced coach thinks that McLeod and Parchment could both win medals in the 110-metre hurdles at the Olympics. “Once Parchment gets his start, we could see Jamaica creating history – a quinela,” he predicted. “With Omar’s early speed, once Parchment gets his start, Jamaica is in for some good times in the hurdles,” he concluded. The early-season form of Omar McLeod has one of his former high-school coaches thinking about the world record. Raymond Graham, who coached McLeod in 2013 at Kingston College (KC), says McLeod’s early speed will help chase Aries Merritt’s four-year-old 110-metre hurdles record of 12.80 seconds. Graham also believes that McLeod and Hansle Parchment could make hurdling history for Jamaica at this summer’s Olympic Games in Rio de Janeiro. Graham isn’t surprised by his former student’s early-season run of 13.08 seconds at the Drake Relays last weekend. “He is the first hurdler I’ve seen with so much speed, and when you have speed,” he explained, “you’re going to run fast”. The long-time coach believes McLeod was unlucky to hit the hurdles in last year’s World Championship final and said: “I think he will break the world record soon.” McLeod ran 12.97 seconds to beat Parchment, the 2012 Olympic bronze medallist, to win last year’s National Senior Championships. However, he struggled in the World Championships final where he placed sixth. Parchment peaked well at the Worlds to be runner-up to Russia’s Sergey Shubenkov. Graham isn’t the first to project world-record potential for McLeod. Just after McLeod’s Nationals wins, 1966 CAC silver medallist Ray Harvey said: “His form is immaculate, impeccable, but his speed is what really, I think, could propel him probably close to the world record.”last_img read more

first_img8 May 2008Scientists and engineers from around the world met in Perth, Australia last month to launch the €22-million preparatory phase of the biggest project ever undertaken in radio astronomy, the international Square Kilometre Array (SKA).South Africa and Australia are the two countries shortlisted for hosting the massive radio telescope.The SKA will be 50 times more sensitive than any existing facility and will tackle some of the biggest questions in astronomy, including searching for earth-like planets and potential life, looking at the first objects in the universe, testing theories of gravity and examining the mystery of dark energy.PrepSKAThe SKA preparatory project, dubbed PrepSKA, will run through to 2011, pulling together international efforts from around the world to finalise a detailed, costed technical design and develop the governance and legal framework for the SKA.The PrepSKA programme will also conduct additional studies of the short-listed sites in Australia and South Africa that are being considered for the SKA.Funding will be provided by the European Union, which has committed €5.5-million, and the 12 participating countries: Australia, Canada, France, Germany, Italy, Portugal, Spain, South Africa, Sweden, the Netherlands, the UK and the USA.“Once PrepSKA is complete, there should be an agreed design for the largest array of radio antennas ever built, allowing interested countries to decide on their involvement with the final SKA project,” SKA South Africa said.Professor John Womersley of the UK’s Science and Technology Facilities Council (STFC), the co-ordinator of PrepSKA, said the SKA “has the potential to be one of the most exciting global endeavours in science, changing the way radio astronomy is done.“The PrepSKA project is a vital preparation stage that will allow the interested partners to bring together their different approaches and priorities and lay the groundwork for a world-class programme.”4 000 antennasConstruction of the SKA is due to start in 2013, subject to successful funding proposals, and to be conducted in phases over seven years. The telescope should start operating in 2015, once a significant portion of the array has been commissioned.The array will comprise approximately 4 000 antennas spread out over a total collecting area of a square kilometre. The antennas will be distributed in about 200 “stations” spread over approximately 3 000 kilometres.If South Africa wins the bid to host the SKA, the core of the telescope – consisting of approximately 3 000 antennas – will be located in the Karoo region of the Northern Cape province, approximately 95km north-west of Carnarvon. The other antenna stations will be distributed throughout South Africa and a number of African countries.South Africa will play a leading role in much of the PrepSKA study, thanks to the knowledge and experience gained in the design and construction of the MeerKAT, an SKA prototype or “pathfinder telescope”.According to SKA South Africa, SA’s report on the MeerKAT project “was very well received” by the nearly 200 delegates at the SKA Forum in Perth in April. These included the international agencies that will fund the SKA, as well as astronomers, industrialists and government officials.South Africa’s MeerKAT projectWork on the design, development and construction of the MeerKAT, located at the site selected for the SKA, began in 2004 and is due for completion and commissioning by the end of 2012.The MeerKAT has been designed by South Africans “in collaboration with the best universities and institutes in the world, including Cambridge, Oxford, Manchester, Berkeley, Caltech, the Netherlands Institute for Radio Astronomy, Astron and others,” said SKA South Africa.The MeerKAT “is intended to be a world-leading centimetre-wave radio telescope for many years”, eventually comprising up to 80 12-metre antennas.A 15-metre prototype antenna has been built from composite materials at the Hartebeesthoek Radio Astronomy Observatory in Gauteng province.“This is the first large antenna in the world to be manufactured from composites,” said SKA South Africa. “Tests on this antenna have improved the design, and an optimized 12-metre antenna will be constructed for a seven-dish array to be constructed in the Karoo by the end of 2009.“The final phase will see the construction of the array of up to 80 dishes by 2012.”SKA South Africa is a project of the Department of Science and Technology, managed via the National Research Foundation.SAinfo reporterWould you like to use this article in your publicationor on your website?See: Using SAinfo materiallast_img read more

first_imgThe weathering of wood is very different from decay; weathering is breakdown at the surface only. While there are a number of forces that contribute to weathering of wood—moisture, temperature, abrasion by wind-borne particles, air pollution—it’s the narrow band of high-energy ultraviolet light in sunlight that is the dominant force (see Image #1).What bare wood looks like when cut or milledImage #2 is an electron micrograph of unweathered wood. You can see how robust the cells appear; we are primarily looking at the lignin in the wood, the chief component of wood that gives it its structure. Wood treatments, particularly primer paints, are formulated to bond and bind to unweathered wood.What weathered wood looks like after UV degradationImage #3 is an electron micrograph of weathered wood, wood exposed to sunlight for a month. You can see how the wood cell structure has deteriorated significantly. Remember this is a surface phenomenon that does not affect the structural integrity of the wood. But this surface degradation has significant impact on how well treatments, such as paint primer, bond and bind to the surface of the weathered wood.A paint primer testResearchers and paint manufacturers have tested the effect of UV degradation on the bonding and binding of finishes to bare wood. It’s dramatic; just a couple or so days of direct sunlight can degrade the wood enough to reduce the quality of the primer bond to the bare wood. Image #4 shows testing done by Sam Williams of the Forest Product Laboratory (FPL). The test boards show that the longer the exposure of bare wood to sunlight, the poorer the bond and shorter the service life of the paint. His conclusion: “Smooth-planed lumber [that is, siding and trim] must be painted promptly during construction.”Lesson learnedPrime or initially treat bare exterior wood as soon as possible. Ideally, go with factory-primed exterior wood cladding components. It doesn’t make sense to pay good money for exterior wood components and not take the time, right away, to protect them from the sun. And in areas of the country with the highest UV index (mostly the southwest and locations at altitude), it’s even more important to get that sunscreen on your naked wood!For more detailed information on the weathering of wood see these resources from the Forest Products Lab:1.

first_imgShooting a live event? Cover all your bases, and maximize your workflow with these practical approaches to film or video production.Shooting events can be stressful, especially when you’re not entirely sure how much coverage you need to capture.  How many wide shots of a wedding do you need? How many close-ups of the tablecloth are necessary? There’s a lot going on — and only one of you to capture it all.If you’re gearing up for a shoot, and this is stressing you out, have no fear: I’ve created a go-to guide that can help you capture all the coverage you need to make a solid edit.Keep in mind that amount of action per event will really determine how much you shoot. If it’s a pretty active event, you might want to repeat the shot list every 15 to 40 minutes. If it’s a basic event and things are slow, I recommend filming per location or every few hours. That being said, use your judgment and try to gauge the fluctuation of how things are flowing.Every shoot is different. The big thing you want to capture is the feeling of the event. Ask yourself How does it feel? What is energy? What looks interesting and unique?Wide/ Establishing ShotsThese are great for entering and exiting a scene. I recommend getting at least 1-5 solid wides.Wide/MediumTry to get a good 3-4 wide/medium shots in the can. An example of this type of coverage would be people interacting or participating in an activity.Close Ups/MomentsIn my eyes, expressions and reactions are important elements to capture at an event. My rule of thumb is usually 15-25 reactions per scene, setup, or location.Close Up/Macro Detail ShotsDETAILS! Details are essential for making a great event or recap video. You want to film the small details that the organizers fought so hard to bring together. I usually gather 15 per scene, setup, or location.For each of these categories, be sure to capture the right moment before moving on to the next shot. There’s no point in gathering all of this coverage if none of it works in the edit.The main thing is to follow your gut and use this guide as an outline. All shoots are different, and so is the coverage you’ll get. This method has helped me immensely, and now I just rely on it as a rule of thumb when filming any sort of event or recap video.Looking for more filmmaking tutorials?
