OAKLAND — The A’s lost to the Texas Rangers, 8-3, on Sunday afternoon. They finished the season 52-27 at the Coliseum. With Tampa Bay’s loss to the Boston Red Sox, the A’s remain two games ahead for the first wild card spot.Tanner Roark continued his rough stretch of games, allowing a career-high four home runs (five total), in a season-low three inning outing. Roark has a 9.69 ERA in his last three starts.A.J. Puk … Click here if you’re unable to view the photo gallery on your mobile device.

A young boy gets training on ball controlskills from one of the Liverpool coaches UK based football team Liverpool FCspent time in South Africa, coachingyoung footballers.(Images: www.oxfam.org)MEDIA CONTACTS• Nicole JohnstonOxfam International+27 12 423 9900/9918+27 82 468 [email protected] Nosimilo RamelaExcitement swept through football-loving communities in South Africa recently when members of UK’s well-known Liverpool FC stopped off at a few sports grounds to give coaching and wellness workshops.The tour ran from 19 to 22 May and covered Gauteng and North West provinces. It was made possible through a partnership between Oxfam International and Fair Play for Africa.“We want to spread our Truth 4 Youth messages,” said Liverpool head of community coach Bill Bygroves, referring to the team’s strategy of using football to teach youngsters how to lead responsible and healthy lives.“The messages we use to teach are: show racism the red card, give bullying the boot, kick drugs into touch, shoot goals not guns, we is better than me, before you please think disease, health is wealth, knives are for eating not for fighting, more important than being a good footballer is being a good person, and you’ll never walk alone.”Bygroves was joined by four other Liverpool coaches. Some of them, like Michael Yates, are also former players for the team. “I’ve played with some of the greats, such as Michael Owen and Steven Gerrard,” said Yates, who became a junior Liverpool player at age eight.I was lucky enough to follow the UK delegation on its third and fourth day in South Africa, as it passed through Soweto and Randfontein, situated south and west of Johannesburg.My first stop was Meadowlands Zone 5 in Soweto, where I saw boys and girls dashing to the nearby stadium after school on Friday afternoon. With football boots in hand, they practised their best moves along the way and, once at the grounds, quickly changed into their kit and started warming up. They were clearly keen to make a good impression as they waited for the Liverpool stars to arrive.The Soweto Ladies Football Club was also there, eagerly anticipating the workshop. Coach Fikile Sithole gathered her team members and gave them a quick talk: “Remember to be disciplined. Take this opportunity to learn and share your skills and your experiences with Liverpool. They are here to learn from you as much as you are here today to learn from them.”Sithole is a former captain of South Africa’s national women’s football squad, which is nicknamed Banyana Banyana, meaning “the girls”.Her sporting career includes playing for Liverpool’s local development team at the tender age of 10, and playing for Swedish women’s club Oxaback Marc IF. But “I returned to South Africa to start rebuilding the Soweto ladies club, which was dying. There were only seven players left,” Sithole said.With the help of fellow coach Colleen Hans, manager Oupa Thebe and public relations officer Thanda Dlamini, she has now grown it into a squad of 32 players.Turning to her players, Sithole announced: “Liverpool is a few minutes away!” Shouts of joy and anticipation rung through the modest arena.After introducing themselves to the Meadowlands group, the coaches split players into different categories. Yates took a group of 10 girls and taught them different techniques, like how to control and protect the ball while also looking out for opponents. The participants listened attentively and practised each move carefully after the demonstration.“We are very honoured to have the team here – it’s a once-in-a-lifetime opportunity to be trained by great coaches,” said Khethiwe Mlangeni from the Soweto Ladies Football Club. “We’ve wanted such an opportunity for a long time, so were grabbing it with both hands.”Yates said they were humbled by the overwhelming response from the players they worked with. “The children have been really enthusiastic and very receptive. Their skills are really good, and I was really impressed by the girl’s technical skills.”At the end of the workshop the coaches gave a talk on healthy living and protection against HIV/Aids. They later thanked the Soweto locals for hosting them and being so enthusiastic during the training. All players got free footballs and T-shirts, while the best performers of the day received autographed posters and official Liverpool football jerseys.‘Humbling’ visitThe UK team took time between coaching clinics to visit disadvantaged communities hard hit by HIV/Aids. One of the stops was in Orange Farm, just outside Johannesburg. “Being there and seeing such poverty was really humbling,” Bygroves said.In Orange Farm they also stopped at a hospice run by a woman called “Mama Rosy”, who cares for the terminally ill. “It was very moving and emotional to see how the community has pulled together to help give those who are sick the best care and comfort during their last days,” said Eddie Sullivan, Liverpool’s children’s coach.Bygroves, who is also the teams’ chaplain, prayed with patients and their families at the hospice, and the others handed out team caps and T-shirts before saying goodbye.“This is one of the memories I will take back with me, and it will stay with me forever,” said Yates.“For the young people here, playing football is more than just a fun sport – it’s an escape to a place they can go to, to leave all their hardships behind. Football brings joy and hope to the young people here. I admire how these youngsters can still laugh and play with us so freely and just let go of their circumstances for a while.”Giving xenophobia the bootOn Saturday the Liverpool team attended the Anti-Xenophobia Football Tournament at the Mohlakeng Stadium in Randfontein. This was held in recognition of the countrywide outbreak of xenophobic attacks in May 2008, which targeted migrants from Mozambique, Malawi, Zimbabwe and elsewhere in Africa. Sixty-two people died in the violence.The Human Sciences Research Council later identified competition over scarce jobs and essential services, such as housing and healthcare, as the main cause of the attacks.“We organised this tournament to unite the community and promote social cohesion,” said Amir Sheikh, the public relations officer for the African Diaspora Forum. “We want people to live together without fear, and we saw football as an effective way of driving that message forward.”The Liverpool delegation was asked to guest-coach the eight teams involved, but they also had time to play against some of the youngsters there. “I found it difficult to play on this pitch, it’s quite bumpy,” said Yates. “The local boys played with such ease, though. That on its own is a testament to their technical skills”.Hundreds of community members supported the tournament and cheered the English visitors on as they demonstrated their ball-handling tactics.A taste of AfricaAfter the action on the pitch the coaches were treated to a spread of African cuisine and dancing by Rwandans, South Africans, Ghanaians, Zimbabweans, Nigerians, Mozambicans, Zambians and Ethiopians.The dancers invited the guests to join in and taught them a few simple moves. The locals clapped and whistled at the sight of the English swinging their limbs and jumping to the beat of African drums.After an elaborate African lunch, the Liverpool members listened and clapped along to a performance of local popular football songs and lively vuvuzela-trumpeting, and then taught the crowd some of their own war cries.Soon one of the team’s best-known anthems, You’ll never walk alone, filled the stadium as locals joined the guests in song.
Interpreting those pesky heat loss calculationsYet another complication could be the energy loss calculations themselves, which were produced with a program called Wrightsoft. The report is complex and “more than a bit confusing for me,” Holodinsky says, but it seems to predict 0.48 air changes per hour.“The assumption is way high and suggests a very leaky house that would have a blower door test of 6+ [air changes per hour at 50 pascals of pressure],” Jerry Liebler replies. “With minimal attention to air sealing, you should be closer to 1.5 ACH at 50 Pascals. Ask your builder to do a blower door test and ask for a guarantee that it’s below 2 ACH @ 50 pascals. Then ask that the infiltration rate for the heat loss calculations be 2/12 = 0.1666 ACH .”In fact, Liebler adds, actual air infiltration is only a fraction of the test number because the test “artificially creates a greater pressure difference than actually will occur.”“With the 2 ACH test data the heat loss due to infiltration should be about one-third of what was calculated,” Liebler continued, “By the way, the proverb ‘garbage in = garbage out’ applies. I’d be very suspicious of all the heat loss calculations and assumptions. For example, were the U-factors of the windows you are paying for actually used, or did they use something else? Triple-pane windows should be U=0.2 or less.”We’re smack dab in the middle of the Information Age, adds Sonny Chatum, so Holodinsky should consider going online and getting a copy of the BEopt software from the National Renewable Energy Laboratory and running his own calculations. Chatum used the software himself to predict the heating and cooling loads at his own house after an energy retrofit (losses dropped from 40,000 Btu/h to 14,000 Btu/h, which Chatum handles with two ductless minisplits).“It is useful to note that sometimes experts and professionals get hung up in their traditional ways,” Chatum added. “Sometimes, and in some ways, the Information Age can possibly make you as much or more of an expert than ‘the expert’ … All the traditional contractors were astonished with what I had done, and did not believe that the minis would be adequate. They were wrong.” Bob Holodinsky was hoping for a better outcome from the heat loss calculations he received for his new Peterborough, Ontario, home — calculations that appear to have upset his plans for heating with a ductless minisplit. “I thought I was on the right track,” he writes in a Q&A post at GreenBuildingAdvisor, “but now I am not so sure.”The 1 1/2-story, slab-on-grade house will be built with 2×6 exterior walls, insulated with blown-in fiberglass and 2 1/2 inches of expanded polystyrene insulation (EPS). Conditioned space totals about 1,900 square feet.There are lots of triple-pane windows on the northeast side of the house, which faces a lake. The living-dining-kitchen area alone is responsible for a heat load of 17,000 Btu/hour, and the house as a whole shows a heat loss of 42,000 Btu/hour.Holodinsky’s builder says that insulation in the roof will equal R-75. Exterior walls will have R-24 insulation between the studs, with an additional R-10 in the exterior foam sheathing. The slab is insulated with 3 inches of EPS.“I was hoping to heat it with a Fujitsu minisplit on each level,” he writes. “Is that still a viable option?” RELATED ARTICLES Too much glass, not enough foamOne problem, says Matthew Nolette, is that 2 1/2 inches of EPS aren’t enough exterior foam for that climate zone. He points to an article by GBA senior editor Martin Holladay on calculating the minimum thickness of exterior foam. However, extruded polystyrene (XPS), with a higher insulating value than EPS, would work at that thickness.Another problem is all that glass on the northeast side of the house, which Nolette says “would be indicative of design desires conflicting with energy goals.”Passive solar building guidelines suggest minimal glass on the north side of the house because windows contribute no direct solar gain but plenty of heat losses. Windows on the east and west sides of the house also should be limited.“You’re in a tough site with northeast views in a cold climate; there will be some performance compromises if you cannot determine how much northerly glass is a lot and how much is enough,” he writes. “Has your builder completed a house with these design goals before? Are they designing it? Do you have access to the designer and are you using a third-party energy modeler?” Calculating the Minimum Thickness of Rigid Foam SheathingEnergy Modeling Isn’t Very AccurateSaving Energy With Manual J and Manual DFrom Fine Homebuilding magazine: Energy Modeling Software: Is It Worth Your Time and Money?Green Basics: Ductless Minisplit Heat Pumps Holodinsky’s misgivings are the topic for this Q&A Spotlight.Heat pumps are not the right optionAlthough he can lower his energy demands by air-sealing and increasing the amount of insulation in the house, minisplits may not be the best fit for this Climate Zone 6 location, writes a GBA reader who calls himself Flitch Plate.“I would be concerned with minisplits as the sole heat source in Peterborough, no matter what the BTUs are,” Plate says. “Heat pumps are the poorest performers and least efficient at the times you need them most: very low temperatures. I would design in a backup heating solution, such as a small wood stove centrally located on the main floor or an electric heat source in each room.”Jason Hyde says he’s not aware of any Fujitsu units suited to Peterborough’s winter design temperatures. Fujitsu says that its XLTH series works down to 15 degrees below zero, Hyde says, but these units produce only 18,000 Btu/hour at 47 degrees F. “I can’t find anything telling me what they will put out at lower temperatures,” he adds. “In any case, two units is still only 36,000 Btu/hour.”Given these numbers, and without seeing plans or heat-loss details, Hyde doesn’t see any single upgrade that will put him within Fujitsu range. Sharpen your pencil, indeedWhen Holodinsky tracked down the energy modeler who worked on the report, he found that a series of miscalculations, sloppy inputs, or erroneous assumptions skewed the numbers significantly.The overworked technician, working on four computer screens at once, listened to Holodinsky’s concerns and made some adjustments to keep program inputs much closer to what the house would actually look like when complete. By raising the R-value of exterior walls, adjusting specs for window performance, and changing a program setting for airtightness, heating loads dropped by 10,000 Btu/h, to a total of 32,000 Btu/h.“Much better,” Holodinsky said.But maybe not good enough.“The heat loss was high and the designer was sloppy from the details imparted here,” writes Morgan Audetat. “DIY heat loads for modern construction with ERV, triple-glazing, and rigid foam in cold climates is not for the amateur or the harried professional.“If you are building your home around your heat source, you need a proper ACCA Manual J. If your builder will agree to a blower door and a specified ACH — good luck with that — then that number can be plugged into the Wrightsoft program and all your worries are over…” Our expert’s opinionHere’s what GBA technical director Peter Yost said:There is not much left for me to deal with here, except to echo these points:Additional or “backup” heat source. Taking a look at some historical and recent winter weather data for this neck of the woods, it’s clear you need to have another heat source in addition to the cold climate minisplit heat pump you have cited.From the WeatherSpark website: “The coldest day of the last 12 months was January 22, with a low temperature of -26°F. For reference, on that day the average low temperature is 8°F and the low temperature drops below -11°F only one day in 10. The coldest month of the last 12 months was February with an average daily low temperature of 1°F.”And for a “down Maine” confirming testimonial, take a look at the info here from Efficiency Maine.Heat load calculations. These are very dependent on the assumptions regarding data you might have on airtightness. Simple programs like Manual J may have a three-level category for airtightness — leaky, average, and better — that is wholly inadequate for higher performing building enclosures when 25% to 40% of the heating load in a climate like this may be due to air leakage. The long and the short of it: get a blower door test to nail down this portion of your heating load.Undersizing any space conditioning equipment isn’t good. But oversizing is less of an issue for heating equipment than it is for cooling equipment. Heating appliances that are a little bigger than necessary provide a quick recovery from deep overnight setbacks, and that’s not such a bad thing.
Indian shooters Heena Sidhu and Annu Raj Singh failed to qualify for the women’s 10m air pistol finals at the 2012 Olympics on Sunday.Heena finished at 12th with 382 points while Annu Raj was 23rd with 378 at the Royal Artillery Barracks. A top eight finish would have taken them into the finals.A series of nines towards the end of the final round saw Heena end just three less than Russia’s Liubov Yaskevich, who totalled 385.Heena began the final round with five consecutive 10s, putting her in prime position for a place in the final. But a string of 9s in the next five shots meant she could only finish 12th.Annu Raj ended with a paltry 91 in the final round when she needed a near perfect round to make the final. She did not have a good start scoring 94 in the first round but stormed into contention with 96 and 97 in the next two rounds.
