LONDON (CMC):Sprint superstar Usain Bolt has confirmed his participation in the London Anniversary Games in July, one of his last outings before he competes at the Rio Olympics in August.The event is set for the Olympic Stadium, which Bolt set alight at the London 2012 Games when he stormed to victories in both the 100 and 200 metres, to repeat as Olympic sprint champion.Bolt will compete in the 100 metres, the marquee event on the opening day of the two-day showpiece on July 22.”The London Anniversary Games will be one of my last races before the Olympic Games in Rio,” the reigning Olympic and World sprint champion said.”It will be good to return to the Olympic Stadium on the Friday night and get more of the special atmosphere that the fans always produce.”I always get great support in the UK, and I expect the stadium to be packed. See you in July.”The 29-year-old Bolt is seeking to become the first sprinter to win both the 100 and 200 metres at three consecutive Olympiads, following on from his success in Beijing eight years ago and at London 2012.While he is yet to confirm retirement, the Jamaican is also widely expected to call time on his career following the Games.British Athletics chief, Niels de Vos, said Bolt’s presence would be a huge delight for fans.”Usain Bolt is a global sporting icon, and this will be one of the last opportunities for families to attend the Anniversary Games and see him compete. I’m sure the British fans will create a special atmosphere under the floodlights in this amazing venue,” he said.”The London Anniversary Games is one of the very best sporting events in Britain and in particular the Friday night will be an incredible exhibition of some of the world’s best athletes, made even more special this year due to its proximity to the Olympic Games.”Last year, Bolt won the 100m at the meet in a time of 9.87 seconds.

Log in Most builders understand that condensation can form when warm, moist air encounters a cold surface. Condensation is bad, and builders want to avoid it. There’s a solution, though: According to building scientists, we can prevent condensation problems in walls by determining a wall’s temperature profile and performing a dew-point calculation. This calculation may require the use of a psychrometric chart.A few brave souls, striving to educate themselves, may consult a copy of ASHRAE Fundamentals to learn more about dew-point equations (see Image 1). That’s what I did — briefly, before I decided to close the book and put it back on the shelf.To wade through this thicket, I’ll attempt to answer a few questions:Understanding temperature profilesBuilding scientists sometimes talk about a wall’s “temperature profile” or “temperature gradient.” The idea is to estimate the temperature of different wall components, assuming certain indoor and outdoor conditions.For example, consider the wall of a house on a cold winter day. If it is 72°F indoors and 0°F outdoors, the siding temperature will be close to 0°F, while the drywall temperature will be close to 72°F. The other wall components will be at temperatures ranging between these two extremes.If we draw a cross-section of a wall, we can calculate the theoretical temperature of any point within the wall. However, since these temperature profiles usually fail to account for air leakage, they are usually inaccurate. Moreover, they represent a theoretical one-dimensional model; since the real world has three dimensions, this model has limited value.What’s a dew-point calculation?Builders or designers perform dew-point calculations to determine whether a certain component of a wall, ceiling, or roof — in most cases, the sheathing — will stay warm enough during the winter to avoid condensation problems.To answer this question,… This article is only available to GBA Prime Members
Australia captain Steve Smith admits he took a sleeping pill as he dealt with a bout of nerves on the eve of the final day of the second Ashes Test after his decision not to enforce the follow-on had given England a sniff of victory.It all worked out in the end with Australia cantering to a 120-run victory to take a 2-0 lead in the series on Wednesday but Smith conceded he might have had a sleepless night if he had not had a bit of pharmaceutical assistance.”I had to have a sleeping pill last night. It has been a pretty tough 24 hours if I’m being honest,” he said.”It’s all part of being captain of your country. You have to make difficult decisions and sometimes you’re going to make the wrong decision.”I’ll think back and reflect over the next day or so and think what I could have perhaps done differently and could have done better, and areas that I can continue to improve in my leadership.”Aussie skipper Steve Smith reflects on a ‘pretty tough 24 hours’ #Ashes pic.twitter.com/i3vUy3bh19- cricket.com.au (@CricketAus) December 6, 2017Only South Africa captain Dudley Nourse against Australia in 1950 had previously lost a Test after failing to enforce the follow-on, and Smith could have joined him if England had managed 178 runs on Wednesday.Smith said he was still undecided whether it was a good decision or not but that he had expected Australia to back it up by batting a bit better than they did by making just 138 runs in their second innings.advertisement”I guess my rationale was that we’re 215 runs in front of the game, if we bat reasonably well then we should be getting up over 400,” he said.”All we needed is one good partnership and the game is dead and buried. We didn’t get that partnership.”Over the last day or so I have had a few different thoughts and I’ve read a lot of things but in the end we won the game so it’s all irrelevant.”Another factor had been keeping his pace bowlers fresh and tiring out the English seamers.”We know it’s a long summer and I think the bowlers we’ve got are very valuable,” he said.”It’s part of an Ashes series, it’s long. And if we can tire their bowlers early in the summer it can make a big difference at the back end.”The winning moment for Australia! #Ashes#ohwhatafeeling @Toyota_Aus pic.twitter.com/WjUpq0aIBE- cricket.com.au (@CricketAus) December 6, 2017Smith, whose 141 not out was the difference between the sides in the first Test in Brisbane, contributed 40 and six runs in his two innings in Adelaide.James Anderson said on Tuesday that he thought England had got to Smith with their sledging. Smith disagreed.”I think the opposite. I think they switched me on to be perfectly honest,” he said.”I think when it got me in my little bubble. I have my little idiosyncrasies. It got me going. They can think what they like but from my point of view it got me going.”Counting down the best moments of a cracking #Ashes contest! @Toyota_Aus pic.twitter.com/zSLu1F1xbf- cricket.com.au (@CricketAus) December 6, 2017
