As virus surges, Trump under pressure to adopt mask

first_imgPresident Donald Trump faced mounting bipartisan pressure Sunday to set an example by wearing a face mask, as his health secretary warned the “window is closing” to gain control of an explosion of infections in conservative-led US states.New coronavirus cases have been surging in more than half of US states, reaching record new highs after months of mitigation efforts applied unevenly across the country and sometimes contradictory messaging from the government.Hardest hit have been southern and western states that pushed for early economic reopenings.But the latest upsurge, pushing the nation’s total of declared cases over 2.5 million and its death toll past 125,000, has prompted a growing chorus of calls for much tougher rules and enforcement.”This is a very, very serious situation and the window is closing for us to take action and get this under control,” Health and Human Services Secretary Alex Azar said on CNN. Topics : ‘Long overdue’ Liz Cheney, a member of the House leadership, has tweeted a picture of her father, the former US vice president, wearing a mask under the words: “Dick Cheney says WEAR A MASK #realmenwearmasks”Vice President Mike Pence has sometimes worn masks in public but stopped short of advocating mask-wearing when he chaired the first briefing in two months of the White House coronavirus task force on Friday.Pence travelled Sunday to Texas for a briefing with Governor Abbott on the pandemic response, but has cancelled upcoming events in Arizona and Florida “out of an abundance of caution.”Asked why the administration hasn’t pushed harder for masks, Pence told CBS on Sunday that “we believe that every state has a unique situation” and that “we want to defer to governors” to decide on rules for their own states.Some Democrats want Trump not only to set an example but to mandate mask-wearing nationwide — including Trump’s White House rival Joe Biden who says he would seek to make masks compulsory in public spaces.Asked on ABC if she would support such a move, House speaker Nancy Pelosi called it “definitely long overdue. “We have the worst record of any country in the world. And the president says we’re making progress.”She added, “The president should be an example. Real men wear masks. Be an example to the country and wear the mask.”  ‘A unique position’ Azar was asked why Trump has refused to set an example by wearing a protective mask in public — even when standing next to mask-wearing health advisors — and reiterated the White House explanation that the president is tested daily and is “in a unique position” as a world leader.But many Republicans who are normally reluctant to criticize the president have been calling more insistently for mask use, with some urging a clearer example from the nation’s leader. “If wearing masks is important, and all the health experts tell us that it is… it would help if from time to time the president would wear one to help us get rid of this political debate that says if you’re for Trump, you don’t wear a mask, if you’re against Trump, you do,” Republican Senator Lamar Alexander said Sunday on CNN.In some areas, mask-wearing has taken on a political edge rather than being seen as a straightforward health choice.Among Republicans calling strongly for mask-wearing are Senator Marco Rubio of Florida — which has set daily records of new COVID-19 cases; Senate leader Mitch McConnell of Kentucky; and Governor Greg Abbott of Texas, another state that has seen a major uptick in cases after moving aggressively to reopen its economy.In Phoenix, Governor Doug Ducey wore a mask on Thursday when he warned fellow Arizonans that “we are getting hit hard right now.” The best defense against COVID-19, he told local media, is to wear protective masks.last_img read more

Rachael Haynes helps Australia survive scare against Sri Lanka

first_imgPerth: Rachael Haynes turned out to be the unlikely hero for Australia as she struck a classy half-century to help the hosts overcome a mighty scare against Sri Lanka in their Group A game at the WACA on Monday.Earlier, Chamari Athapaththu’s half-century set Sri Lanka on their way but two wickets apiece from Nicola Carey and Molly Strano held them at 122 for six.Australian hearts were racing when Alyssa Healy, Ashleigh Gardner and Beth Mooney all fell within the first four overs of the chase. But a stunning 60 from Haynes in a solid partnership with captain Meg Lanning ensured their tournament hopes stayed alive with a five-wicket victory at the WACA.Australia did not hesitate in showing their intent as Megan Schutt struck early with her third ball to remove Hasini Perera for a duck.It took until the end of the powerplay for Athapaththu to see her next partner fall as Umesha Thimeshani was removed by Carey for 20.Brief scores: Sri Lanka 122/6 (Chamari Athapaththu 50, Nicola Carey 2/18); Australia 123/5 (Rachael Haynes 60 Udeshika Prabodani 2/17).

Kootenay suffers meltdown, drops heartbreaking 5-4 loss to North Island

first_imgIt was a collapse of major proportion.Leading 4-0 with 10 minutes remaining in the game, the Kootenay Ice watched as the North Island Silvertips scored five unanswered goals to steal a 5-4 BC Hockey Major Midget League victory Sunday at the NDCC Arena.The win allowed the Silvertips to sweep the BCMML series after opening with a 4-1 win Saturday in Nelson.Five different players — Owen Hardy, Jack Long, Sage Lim, Brett Stapley and Tyler Topping, with the winner with time running out — scored for North Island. Three of the goals came in the final 85 seconds with the Silvertips net empty for two of the markers.“We played great for 50 minutes,” said an Ice coach after the game.Kootenay held a 1-0 lead after one period on a goal by Luke Madge of Castlegar.Blake Sidoni of Trail, Shawn Campbell of Castlegar and Korbyn Chabot of Cranbrook increased the lead to 4-0 after 40 minutes.Solomon Burk of Castlegar was in goal for Kootenay.Saturday, North Island scored three times in the third period to break open a close game.Kootenay, 5-26-5, travels to Abbotsford this weekend for a two-game set against the Fraser Valley Thunderbirds.The Ice host Vancouver Northwest Giants in Nelson February 28 and March 1 during the final regular season weekend.last_img read more

SENSATIONAL STAR STAKES QUOTES

first_imgPETER EURTON, BETTYS BAMBINO, WINNER: “It’s been a great ride (winning four in a row). We had one little hiccup when he ran on the dirt (fourth last April 25 at Santa Anita) and he didn’t get involved. I blame myself for that, but ever since then, he’s learned how to run.“I’d like to see him go a one-turn mile down the road. He’s had some issues with tibias, shins, little things like that. The neatest thing about him is he puts himself in a good spot. He could go to the lead any time he wants to, but he saves himself by pacing himself. If the pace is slow, he’ll be on the lead; if it’s fast, he’s able to rate himself without being very far off the lead. He doesn’t have to give away a lot of ground.”MARTIN JONES, AMBITIOUS BREW, SECOND: “I was proud of him, he ran well. Bettys Bambino is pretty sharp right now and (Ambitious Brew) hasn’t run in a while. He ran a good race, though; he’s a nice horse.” TRAINER QUOTES MARTIN GARCIA, BETTYS BAMBINO, WINNER: “I had a lot of horse when we crossed the dirt; I was really comfortable. I wanted a clean trip. He’s a really big horse and it’s better when I put him to the outside where he can run free; he loves the downhill.“Last time out he hurt my knee pretty good in the gate but the gate guys have done a really good job with him, they have really helped him. They make him quiet down and he broke clean today.” JOCKEY QUOTES NOTES: The winning owners are Sharon Alesia of Carlsbad; Michael Mellen (Bran Jam Stable) of Minnesota; and Joe Ciaglia of Upland.-30-last_img read more

Plans in gear for Copa Cocacola Africa camp

first_img“We are working with partners across the continent to develop a Copa Africa camp because as you know there are multiple countries with Copa Coca-Cola. We want to have a world cup of sorts because we have seen a lot of talent especially in the Kenyan tournament and we would want to develop it,” Nzioka said.In previous years, there have been Copa camps organized in South Africa and at one point there was a partnership with coaches from English premier League side Chelsea FC who came down and helped train the young lads and their coaches.Meanwhile, Nzioka says the tournament celebrating it’s 10th anniversary this year has seen tremendous success and believes there will be more in the coming years.2018 Copa Coca-Cola Champions St. Anthony’s Boys from Kitale celebrate with their trophy at the Hill School in Eldoret.St. Anthony’s Boys from Kitale won this year’s competition after beating St. peters Boys from Mumias 3-1 on penalties in the final in Eldoret last week.Biggest among the highlight players to have come through the tournament is Harambee Stars striker Michael Olunga who starred for Upper Hill High School before making the top tier moves to Thika United, Tusker FC and Gor Mahia.Olunga currently plies his trade in the Chinese top tier with Guizhou Zhicheng having had his first pro stint in Sweden with Djugardens and last season played in the Spanish La Liga with FC Girona.“The 10 years have been a learning and growing experience for us. The reason we got into Copa was because we wanted to engage the youth on a platform they could connect with and for the youth that is either music or football,” Nzioka explained.“Copa has grown year in year out and the reason we went for the Under-16 is because that is the age where youth discover their talent and we wanted to play a part in nurturing it and opening the doors for them,” he added.Coca-Cola Senior Franchise Brand Manager Rodney Nzioka receives a commemorative plaque from an official of the Kenya Secondary School Sports Association as they celebrated 10 years of existence.Previously, the company used to run the tournament on its own but since 2016, they have partnered with the Kenya Secondary School Sports Association (KSSSA) and the tournament has been made part of the school games calendar.“The reason we partnered with KSSSA is we wanted to increase the scale of Copa and with schools it allows us to touch all secondary schools in Kenya. Also, they provide a great logistical and marketing support for Coca-Cola so it makes it easier,” added Nzioka.“I would give a 12 (On a scale of 1-10)! It has been a successful endeavor with the company and there are a lot of superstars that played their first organized game through Copa, not only players but coaches as well, we develop the sport all round,” further added the Marketing boss.Meanwhile, Coca-Cola signed a three-year partnership with KSSA that will see them sponsor the entire Term 2A National School Games to the tune of Sh21.5mn per year, taking over from Brookside who were erstwhile sponsors of the games.The partnership kicked off this year with the School Games held in Eldoret where the company were headline sponsors for the Copa U16 tourney, U19, racquet games, volleyball, netball, rugby, decathlon, heptathlon and cross country. 0Shares0000Coca-Cola Senior Franchise Brand Manager Rodney Nzioka hands over the winner’s trophy to the 2018 Copa Coca-Cola Champions St. Anthony’s Boys from Kitale at the Hill School in Eldoret.NAIROBI, Kenya, Aug 6- Plans are on to organize an Africa Copa Camp that will see winning teams from all round the continent gather in one central location for a training program as well as a ‘African Cup’ tournament, Coca-Cola Senior Franchise Brand Manager Rodney Nzioka has told Capital Sport.In an exclusive interview with Capital Sport, Nzioka says just as has been the tradition in years before, the beverage company will look to ensure the talents showcased in the Under-16 tournaments all across the continents is developed and improved. 0Shares0000(Visited 3 times, 1 visits today)last_img read more

Finding South Africa’s next Olympic swimming champion in Kayamandi

first_img12 July 2016Welcome to the team @SongoFipaza #stoked2ride pic.twitter.com/51CUMlqKbo— SpecializedZA (@SpecializedZA) February 16, 2015Kayamandi, on the outskirts of Stellenbosch, might not have a swimming pool but it hasn’t stopped resident Songo Fipaza from following his dreams of coaching kids to use the sport for upliftment. He wants to build the township a swimming pool to develop aspiring swimmers. Perhaps one day they could become Olympic gold winners.Fipaza and his non-profit organisation Songo.info is currently raising funds to build a community swimming pool and help improve the lives of the Kayamandi youth.Local sporting heroFrom zero to hero: what drove @SongoFipaza to do the Ironman? @virginactiveSA > http://t.co/sjSl4SOafc pic.twitter.com/lT2e7wHMzd— Bike Hub (@bikehubber) April 7, 2015Fipaza is renowned in his hometown for following his dreams and helping others do the same.While he was an avid soccer and rugby player in his youth, he was inspired by the successes of South African athletes at the Olympics, particularly, Elana Meyer who won a silver medal at the 1992 Barcelona Olympics. It was the same year South Africa returned to the games after almost 30 years. “I asked myself why I couldn’t do that. So I decided to do it,” Fipaza told News24 recently.He joined a local running club and made road running his passion, competing in over 20 marathons since. He began cycling and mountain biking in 2004, competing in the Cape Epic and other local cycling events. The love of cycling inspired him to begin the Songo.com NGO in 2008 with the support of Swiss mountain bike champion Christoph Sauser. The organisation raised over R200 000 to build a cycling track and recreational centre on vacant piece of land in [email protected]: From sinking to swimming 3.8km unaided at @IMSouthAfrica in less than 6 months. #FollowYourConviction pic.twitter.com/ywlzSTrlcX— RECM (@RECM_Online) April 7, 2015Sport centre for the youthThe centre is not only a sports club, but also a place where township youth can go to after school. It has a computer centre for doing homework and a ‘chill-out’ area where kids can safely hang out with friends. About 80 kids attend the centre, riding bikes and staying off the streets.“Children in the township can do and excel in any sport they learn, given the opportunity,” Fipaza told News24, “it’s important for them to see that there’s more to life than what they see in Kayamandi. Seeing the rest of the world gives them perspective.”Fipaza cites the example of Kayamandi’s own up-and-coming sporting hero, Azukile Simayile. The 23-year-old upcoming duathlon competitor is quickly attracting attention around the world in the sport that combines road running and cycling. Simayile has finished in the top 10 of the sport’s World Championship three years running.Getting kids in the poolHis next challenge is to get the kids swimming. Fipaza himself only learnt to swim in 2015 so that he could compete in the Iron Man triathlon. “[Most of the kids here] can’t swim because they don’t have access to a facility where they can safely learn how to stay above water. We need to change that and develop this sport so that we can see a township kid representing SA at the Olympics, not just those who attended suburban schools or had a pool at home.”He hopes that the pool can be used to teach everyone in the community, including adults and pensioners, how to swim. He would like to get the whole town interested in sports in water and on land.Fipaza raised funds together with the South African Sports Trust. He crowd- funded his run in the London Marathon in April this year, raising R60 000 for the cause. While the R15-million price-tag for a fully functional indoor swimming centre might seem a little ambitious, Fipaza is determined to achieve the dream. He is constantly negotiating withsponsors and donors who want to make a difference for the people of the area.“Who knows, some of the best competitive swimmers may be right here, waiting to be trained,” he said.Listen to a full interview with talk radio 702’s Kieno Kammies on Fipaza’s future plans for youth development in Kayamandi.Source: News24last_img read more

Growing our Generation: Our jump into the sheepindustry

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Levi and Krysti Morrow from Morgan County are the editors of the Sept. 23, 2019 Growing our Generation enewsletter, featuring insights and ideas directly from Ohio’s young farmers and food and agricultural professionals.Hi! We’re Levi and Krysti Morrow, your guest editors for the Growing Our Generation e-Newsletter this week! With the “help” of our 15-month-old son, Charlie, we own and operate Rocky Knob Farms in McConnelsville.  We are the u-pick strawberry and pumpkin source in Morgan County and now are dipping our feet into the commercial hair sheep business. Krysti spends her time split between mom life and farm life managing the day to day chores, marketing and planning for our u-pick operations and farmers markets. Levi is an agriculture education teacher at Morgan Local Schools in our county and does all the cropping and haying for the farm.In our 2017 edition, we discussed the importance of business planning, knowing your resources as a beginning farmer and what exactly we do with our leftover pumpkins. Thanks for joining us this week as we dive into some cool ideas!Sheep in AppalachiaOur jump into the sheep industry really took off in March of this year. I (Krysti) found myself in a sticky situation that I wasn’t really strong enough for. A calving cow was having a hard time and although I was able to pull the calf I couldn’t – by myself – move the cow around to help her circulation. Thankfully, a family member got home just in time to help move her and all ended up fine.  That was a big wake up call for me and started the thought process that maybe cattle weren’t going to be the path we followed for our operation.  Sheep, hair sheep specifically, were the livestock we found that seemed the best fit and so far we are enjoying learning more and more.  One of the things we found helpful in deciding was the outlook for the sheep market; with the growing ethnic population in America, the market is seeing more and more of a demand for lamb.  The other major factor that helped us decide was how our pastures lay and the shape of the land. In Southeast Ohio there aren’t many flat places and sheep are adequately designed to be able to graze a hillside more efficiently than cattle. We found this article, shared by the OSU Sheep Team, very interesting from the perspective that sheep may be one answer to repurposing some of the grown-up land in Appalachia and revitalizing some parts of our small communities. U-pick to answering consumer questionsWhen we opened the u-pick pumpkin patch for the first time in 2016, our two main goals were to make enough money to cover the mortgage payment and to help people understand how modern agriculture actually works by having conversations and answering their questions. It’s hard to start those conversations though just off the cuff. I mean, how do you ask someone what they think about modern agriculture without seeming too aggressive?We found that over the course of that season, a handful of people did ask us about how we fed our cattle at the time and made hay for them to eat over the winter and how we planted our pumpkins. Once we added strawberries in the spring of 2018, the conversations came a little more easily, likely because we were providing a product that would actually be eaten not just sit on your porch and look pretty. More and more moms asked us if we sprayed our strawberries with any pesticides and how we felt about our food system in America. A lot of their concerns seemed to stem back to the labels they see in the grocery store and what they actually mean.Now some of the people who asked us questions, already had their minds made up that if a product was sprayed with pesticide it was bad and they didn’t want anything to do with it – there was no changing or easing their mind.  Others though were truly asking out of curiosity and wanted to know our opinions as farmers and the ones that are producing food. I think the portion of people in the middle – those that don’t know and are willing to listen and learn – are the group we’re looking to speak with and share the story of what happens on our farm with.  If you are into listening to podcasts, What The Farm Podcast with Rob Sharkey and Leslie Kelly is a really good one when it comes to learning how we can relate more to the public.  We’ll try to do a better job of sharing what goes on on our farm from day to day to help the public really see how their food is grown, it can’t hurt.

Do These Walls Need a Poly Vapor Barrier?

first_imgZane Bridgers is building a single-story house in northern New Mexico and has nearly completed the framed exterior walls. As his mind turns to air sealing, he’s considering whether to install an interior vapor barrier — and whether his uncle, a builder of 40 years, is giving him good advice on how to proceed. Walls on the slab-on-grade structure will include R-19 fiberglass cavity insulation, 5/8-inch OSB sheathing, a 2-inch layer of polyiso rigid insulation, a drainage layer and, finally, three-coat stucco. In the roof, Bridgers plans 6-mil poly under the drywall, followed by 2 inches of polyiso, R-38 fiberglass batts, a 2-inch ventilation channel, OSB sheathing and metal roofing. “This is a predominately cold and dry heating climate with big temperature swings,” Bridgers writes in a Q&A post of the Climate Zone 5 locale. “I was talking with my uncle who has been a builder here for 40 years. He was explaining the importance of dry heat for optimal performance of fiberglass insulation, hence his recommendation to put the 6 mil plastic on the ceiling … I was planning to tape the foil faced polyiso for this effect, but he thinks it’s a waste of time and effort vs. the 6 mil poly.”RELATED ARTICLESWorries About Trapping MoistureSite-Built Ventilation Baffles for RoofsCalculating the Minimum Thickness of Rigid Foam SheathingOne Air Barrier or Two?Vapor Retarders and Vapor Barriers Bridgers is equally concerned about another bit of advice he’s been given: Add a layer of poly to the walls. “This caused a bit more concern as it seems it could potentially trap moisture in the wall cavity, especially since I had planned foil-faced polyiso under the stucco, also taped,” Bridgers adds. “He suggested leaving somewhere for the moisture to go.” Bridgers has two other questions. First, is it a waste of time to seal the OSB and framing when the exterior foam and drywall seem like much easier ways of controlling air leaks? And second, with a continuous layer of rigid foam over the wall sheathing, where is the point in the assembly where condensation is likely to occur? Those concerns will get us started on this Q&A Spotlight. Water doesn’t need to escape GBA editor Martin Holladay, referring Bridgers to an article he had written on the topic previously, notes that interior moisture doesn’t really need to go anywhere. “Water doesn’t need to escape from your house,” Holladay writes. “Although it’s true that indoor air is warm and humid during the winter, while outdoor air is cold and dry, that doesn’t mean that indoor moisture needs to ‘escape’ from your house. It’s perfectly OK if the indoor moisture stays where it is without ‘escaping.’ ” Holladay explains that walls with exterior rigid foam should never have interior polyethylene, since foam-sheathed walls need to be able to dry to the interior. Either polyiso or expanded polystyrene (EPS) insulation would make a good choice, and taping the seams would be time well spent. “Air sealing efforts are almost never a waste of time,” he says. “Whether or not you need redundancy (basically, multiple air barriers) depends on your airtightness target and your budget.” What about Bridgers’ concerns about condensation inside the walls? “The idea is to specify enough rigid foam on the exterior of your wall sheathing so that condensation does not occur,” Holladay says. “In your climate zone, your rigid foam needs a minimum R-value of R-7.5 if your walls are framed with 2x6s. “Skip the interior polyethylene,” he adds, “pay attention to airtightness, and everything will be fine.” What about venting the roof? If the walls are better off without the poly, should it still be used in the ceiling? Bridgers asks. There’s no code requirement for including a vapor barrier on the interior side of a vented roof assembly, Holladay replies. The most important thing is airtightness, not preventing vapor diffusion. Drywall can be an air barrier, providing Bridgers pays close attention to sealing any penetrations, particularly the electrical boxes. Bridgers sees a problem with adding foam or plastic ventilation baffles above the fiberglass in the roof because either would prevent moisture from being wicked out of the insulation. “The purpose of the vent channel is to help keep the roof sheathing dry,” Holladay says. “You are not trying to wick moisture out of the fiberglass … You aren’t trying to help indoor moisture escape. It’s OK if indoor moisture stays where it is, all winter long.” One air barrier is enough Peter Engle writes that Bridgers has three potential air barriers in the ceiling: the foil facing on the foam insulation, the poly, and the drywall. “You only need one, well detailed and airtight,” Engle says. “If you can make the drywall airtight, you can skip the poly and use any polyiso foam you want, or EPS foam. If you are worried about the drywall being airtight, you can tape the seams in the foil polyiso.” Jon R, however, suggests there’s nothing wrong with multiple air barriers. “More air barriers will generally outperform one,” he says. “If you can only have one, the best (for your climate) is the interior side.” Addressing the risk of condensation Jon R adds that the choice of exterior foam may make a difference to how well the wall performs: “With external foam, a wall that can dry a little to the exterior (say EPS) will outperform a similar wall that can’t (say same R-value of foil-faced foam).” He takes issue with the idea that a wall must be designed so that there is a zero chance of condensation taking place. “The idea is to reduce the amount of condensation to the point where it sometimes occurs but isn’t enough to cause a problem,” he writes. “Going beyond that, all the way to ‘no condensation’ is unnecessary expense. Some in-wall condensation *will occur* at the minimum recommended foam R values.” Holladay replies: “When sheathing is cold in the winter, and in contact with warm humid air, what happens isn’t really condensation. It’s sorption. The moisture content of the cold OSB or plywood sheathing increases when the warm humid air is in contact with it.” That said, the building science in this case is clear. When the exterior foam is thick enough, the sheathing stays dry. If the foam is too thin, the siding may get damp, which is risky. With that in mind, Bridgers asks, would a 2-inch layer of polyiso with an R-value of 13 be a better bet than a 2-inch layer of EPS, with an R-value of 8? “That’s exactly the right type of question,” Jon R replies. “WUFI might provide a useful answer. Forced to weigh various factors and guess in your case (never a good way to do design), I’d say the R-13. Better than either if it were unfaced/higher perms.” Agreed, says Holladay: R-13 is preferable to R-8. Our expert’s opinion GBA technical director Peter Yost made the following points: Cavity or interstitial condensation: There are two primary drivers of this phenomenon: the difference in temperature between the interior and exterior, and the interior relative humidity. Yes, it’s plenty dry in New Mexico during the winter, but occupants can generate quite a bit of moisture (for more, see this). So, make sure you manage interior sources of moisture and have humidity-sensing devices so that occupants know what the interior relative humidity is. Location and nature of air control layer/barrier: If I only get to choose one location for an air barrier, I choose the exterior, for two reasons. One, it’s much easier to get continuity on the exterior (no intersecting interior partitions or floor assemblies to worry about). Two, exterior air barriers deal better with wind-washing at the corners of buildings. Continuity is key. It’s easy to designate elements of the air control layer, but more difficult to get them all connected. Pick one plane for the air barrier, and then make it continuous. If you can get more than one air barrier, great. But one continuous barrier is way more beneficial than two or more discontinuous ones. Building assembly drying potential: It’s ideal to select every individual layer of an assembly (based on vapor permeance) so that there is drying in both directions, but our assemblies are complex enough these days that settling for drying potential in one direction is reasonable. Avoid selecting Class I — and if you can, Class II — vapor retarding materials on one side of your assembly or the other to get that single-direction drying potential. Bottom line: There’s absolutely no need for polyethylene. Don’t put in a Class I vapor retarder/barrier unless you have to.last_img read more
