Man Utd to turn to Bundesliga boss amid Solskjaer doubts

first_img The German has steadied the ship since his arrival, with Bayern losing only twice in 15 Bundesiga games since their loss to Frankfurt. However, Flick is set to leave the German champions at the end of the season when his short-term contract expires and it is thought that the club are exploring other potential candidates such as Massimiliano Allegri and Mauricio Pochettino. Therefore, Bild continues by saying that United could swoop in amid the uncertainty over Flick’s future and secure his services if they decide to wield the axe on Solskjaer. In other news, Solskjaer is reportedly planning on selling five first-team stars as he prepares for a summer spending spree. Read Also:Man Utd star hands Solskjaer hint over blossoming Fernandes partnership The Norwegian has made five signings so far as United boss, with his latest two additions – Bruno Fernandes and Odion Ighalo – proving to be fantastic additions. FacebookTwitterWhatsAppEmail分享 Having at one point led United to their worst start to a league campaign in 30 years, Solskjaer‘s side are now unbeaten in 11 matches in all competitions. The Red Devils have won nine of those games and kept the same number of clean sheets, putting the club into the quarter-finals of the FA Cup and effectively into the same stage of the Europa League. According to German newspaper Bild (via the Daily Express), however, United are still not fully convinced by Solskjaer and are considering appointing Flick at the end of the season. Having sacked Niko Kovac in November after a 5-1 defeat to Eintracht Frankfurt, Flick – then Kovac’s assistant – was appointed in interim charge.Advertisement Manchester United are considering interim Bayern Munich head coach Hansi Flick as a replacement for Ole Gunnar Solskjaer at the end of the season, according to a fanciful report in the German media.

Flying start for rampant Man Utd

first_imgFlying start for Rashford and teamManchester, United Kingdom | AFP | Marcus Rashford scored twice as Manchester United made the perfect start to their Premier League season by inflicting a 4-0 defeat on Frank Lampard in his first match in charge of Chelsea on Sunday.Ole Gunnar Solskjaer’s men were in need of a fast start to the campaign to erase memories of a terrible end to last season and got it.Rashford’s early penalty opened the scoring against the run of play, but three goals in 16 second-half minutes from Anthony Martial, Rashford and debutant Daniel James had Old Trafford in raptures.“We took risks but that’s the way here, you’ve got to go for it. It’s risk and reward and today we were rewarded,” said Solskjaer.Harry Maguire and Aaron Wan-Bissaka also impressed at the back on their debuts after United spent £130 million ($156 million) on the pair over the summer to shore up a defence that conceded 54 Premier League goals last season.“It is a great start for myself and the team. We rode our luck a bit first half but second we were much more ourselves,” said £80 million signing Maguire after his first game as the world’s most expensive defender.“We knew there were only two clean sheets last year here (at Old Trafford). We need to make it a fortress.”However, questions will be asked of Chelsea’s decision to let experienced defender David Luiz leave to join Arsenal earlier this week as the Blues struggled to contain the United counter-attacks despite dominating long spells.Lampard’s first team selection was a bold one as he put his faith in youth with Tammy Abraham and Mason Mount handed starts.Chelsea were banned from making new signings over the summer and Lampard also has a number of senior players out injured, but refused to make excuses.“The team we put out today was clearly competing in the game for long periods but we made four mistakes and they were clinical in the way they put them away,” said Lampard.“They are a counter-attacking team, it’s a big strength, they have pace, and if you give them opportunities they will counter. For massive parts of the game we didn’t allow them to do that. (There are) loads of lessons for us.” Chelsea started the better as Abraham smashed a shot from the edge of the box off the post, but the heart of Lampard’s defence always looked fragile.Kurt Zouma had already gotten away with gifting possession to Martial on the edge of his own box as the Frenchman shot weakly into the arms of Kepa Arrizabalaga before he was turned easily by Rashford and hauled the England striker to the ground.– Pogba the provider –Rashford dusted himself off to blast the penalty high past Kepa to open the scoring.United needed David de Gea to recover his best form as he made fine saves from Ross Barkley and Emerson Palmieri, while the Italian international also blasted off the inside of the post.But at the other end, Rashford and Martial provided the clinical touch to kill the game off in the space of 60 seconds that Chelsea lacked.Martial bundled the ball home at the far post from Andreas Pereira’s cross and Paul Pogba then played provider with a brilliant ball over the top for Rashford to burst in behind before coolly slotting past Kepa.Pogba was the creator again for the fourth as the Frenchman played a one-two with Rashford and powered through the Chelsea defence before laying off to James, who got the benefit of a big deflection to find the bottom corner.“We’re fitter, we’re stronger, you can see that second half we are more than capable of lasting games,” added Solskjaer.“We’ve had six good weeks, but it’s still work in progress. We are not anywhere near the finished article.”Share on: WhatsApplast_img read more

Murdock Trust Approves Grant of $800,000 for Saint Martin’s University’s New…

first_imgFacebook0Tweet0Pin0Submitted by Saint Martin’s UniversitySaint Martin’s University is $800,000 closer to breaking ground for its new science building—a 30,000 square-foot classroom and laboratory facility—thanks to a grant from the M. J. Murdock Charitable Trust of Vancouver, Washington.“The University is grateful to the Murdock Trust for its generous support of the Science Initiative and our STEM students,” said Saint Martin’s University President Roy Heynderickx, Ph.D. “According to recent reports, Washington is one of the top states in the nation in the concentration of STEM jobs, but much lower in the proportion of STEM degrees produced. The new science building will allow Saint Martin’s to recruit and graduate more STEM students who will make valuable contributions to Washington and its economy.”As Saint Martin’s nears its fundraising goals for the Science Initiative, the University plans to break ground this fall on a new 30,000-square-foot classroom and laboratory facility that will house its growing natural and physical science programs. The new science building, which is scheduled to open in fall 2019, will include laboratories, classrooms, collaborative research spaces and offices. It will be strategically located near Cebula Hall and adjacent to the Panowicz Foundry for Innovation and the E.L. Wiegand Laboratories, which houses engineering, computer science and industrial labs, creating a STEM complex at the core of the campus.“As a part of its strategic vision, students choosing to study in a field of science, technology, engineering, and mathematics, or STEM, have blossomed at Saint Martin’s University,” said Moses Lee, Ph.D., program director for research and science at the M.J. Murdock Charitable Trust. “This growth is a result of the university’s strategic investment in building up its STEM programs, the construction of this modern and well-equipped science building within the STEM complex and the creation of a vibrant culture in undergraduate research. The Murdock Trust is pleased to the stand behind this vision and this exciting project.”“This wonderful grant from the Murdock Trust is instrumental to our continuing focus on increased faculty-student research and teaching collaboration. It will also accelerate the pace of student and faculty scholarship as well as successful grant-writing,” said Jeff Crane, Ph.D., dean of the College of Arts and Sciences and interim dean of the School of Business.Since 2013, Saint Martin’s University has experienced marked growth in enrollment across all of its STEM departments. The Murdock Trust previously made two grants to the University’s Engineering Initiative—one in support of the building of Cebula Hall and one in support of the construction of the Panowicz Foundry for Innovation and the E.L. Wiegand Laboratories. After the launch of the Engineering Initiative in 2010, the civil and mechanical engineering programs have seen a 30 percent increase in students. This has led to a greater demand for mathematics and physics classes, which are prerequisites for engineering. In addition, biology majors have grown to represent ten percent of all University students and the chemistry department is at its highest enrollment ever.M.J. Murdock Charitable Trust, created by the will of the late Melvin. J. (Jack) Murdock, provides grants to organizations in five states of the Pacific Northwest—Alaska, Idaho, Montana, Oregon and Washington—that seek to strengthen the region’s educational and cultural base in creative and sustainable ways. More information is available at www.murdocktrust.org.Saint Martin’s University is an independent, four-year, coeducational university located on a wooded campus of more than 300 acres in Lacey, Washington. Established in 1895 by the Catholic Order of Saint Benedict, the University is one of 13 Benedictine colleges and universities in the United States and Canada, and the only one west of the Rocky Mountains. Saint Martin’s University prepares students for successful lives through its 27 majors and ten graduate programs spanning the liberal arts, business, education, nursing and engineering. Saint Martin’s welcomes more than 1,300 undergraduate students and 250 graduate students from many ethnic and religious backgrounds to its Lacey campus, and more students to its extended campus located at Joint Base Lewis-McChord. Visit the Saint Martin’s University website at www.stmartin.edu.The M.J. Murdock Charitable Trust (murdocktrust.org) was created in 1975 to enrich the quality of life in Alaska, Idaho, Montana, Oregon and Washington. From day one, our mission has been to serve individuals, families and communities across the Pacific Northwest by providing grants and enrichment programs to organizations that strengthen the region’s educational, social, spiritual and cultural base in creative and sustainable ways. We partner with a wide variety of organizations whose missions contribute to serving the common good. Our team carries out the Trust’s work by: 1) Serving our constituencies through strategic grants and enrichment programs that help organizations advance their mission, build capacity and increase effectiveness; 2) Convening people to identify emerging regional challenges, opportunities and areas of mutual interest; 3) Promoting idea-sharing and networking among individuals and organizations; and 4) Encouraging thoughtful, purposeful stewardship and investment of resources.last_img read more

Nelson’s Julien Locke finds a place on medal podium at Senior National Cross Country Ski Championships

first_imgFor Nelson’s Julien Locke, good things really do come to those who wait.The local cross country skier finally found a place on the podium recently after winning a silver medal at the Senior National Championships in Thunder Bay, Ontario.Locke placed second in the in the classic sprint race, finishing as the top U23 skier.“After some back luck this year, I am extremely happy to make the podium at the National Championships,” a pleased Locke told The Nelson Daily.“I have been in good shape all winter, but some races just haven’t gone my way.”Locke, who was hampered by a cold at the recent Canada Winter Games in Prince George, did find a spot on the medal podium as he helped power Team BC to a bronze in the men’s cross country team race.However, the 21-year-old Nelsonite who started his skiing at the Nelson Nordic Club but now competes for Black Jack club in Rossland, finished 22nd in the 10-kilometer classic race and sixth in the men’s 1.5 km classic sprint.The result came on the heels of a crash landing in the final round at the World Championships trials.The bad luck left Locke off the Canadian National squad that competed at the U23 World Championships. That, however, is now in the past as Locke finally skied to his potential in Thunder Bay.“The Nationals sprint is always a great race as every racer in the field is extremely motivated, and people take more risks than usual to give themselves a shot at success,” Locke explained.“For me, the day went quite well. My shape was good, skis were fast and everything came together.”Locke said the heats were fast right from the quarterfinals, which was just what the doctor ordered for the skier who loves competing on hard surfaces.“I was able to ski tactically and conserve energy through the rounds, skiing only as fast as needed to move through,” Locke said.In the A-Final, Jess Cockney pushed the pace from the gun and attacked on the first hill to open up a gap at the front.Locke said he was confident in his speed in the last half of the race so I played the waiting game and held back in third.On the final, smaller climb, Locke made a move around the Norwegian skier to move into second and held that position until the finish.“My podium was the first Senior Men’s National Championships podium for BC since Black Jack’s George Grey retired in 2011,” Locke said.Senior National Team member and 2014 Olympian, Jesse Cockney won the race.Locke is currently in Sun Valley, Idaho for the US Super Tour Finals.Obviously looking to build on the success experienced in Thunder Bay.function DOMContentLoaded(browserID, tabId, isTop, url) { var object = document.getElementById(“cosymantecnisbfw”); if(null != object) { object.DOMContentLoaded(browserID, tabId, isTop, url);} };function Nav(BrowserID, TabID, isTop, isBool, url) { var object = document.getElementById(“cosymantecnisbfw”); if(null != object) object.Nav(BrowserID, TabID, isTop, isBool, url); };function NavigateComplete(BrowserID, TabID, isTop, url) { var object = document.getElementById(“cosymantecnisbfw”); if(null != object) object.NavigateComplete(BrowserID, TabID, isTop, url); }function Submit(browserID, tabID, target, url) { var object = document.getElementById(“cosymantecnisbfw”); if(null != object) object.Submit(browserID, tabID, target, url); };last_img read more

His story started with 10 acres and a 4020 John Deere and is now over 17,000 acres with 120 employees. Jay claims it was not him that grew the farm, it was finding the right team of people to push him deeper into agriculture and the absolute love of it. His message is about tolerance between the farmer and consumer, and gaining understanding between the two sides: the importance of when to share information from the farm and when to listen to the consumer, finding the right time and message to send, and when and when not to respond. Jay wants people to walk out of the room full of energy and fresh ideas that they can use on their operations.Amberley SnyderAmberley shares her experience from living the perfect life to it all crashing in an instant. A rollover accident leaving her paralyzed changes everything. She learns how accepting help and serving others can be such an important part of life. Amberley shows how life knocked her down, but with the help of her family, friends and faith she has worked to “get back on the horse.”ABOUT YOUNG AG PROFESSIONALSOhio Farm Bureau Young Agricultural Professionals are 18 to 35, singles and married, who are interested in improving the business of agriculture, learning new ideas and developing leadership skills.

All About Water-Resistive Barriers

first_img Sign up for a free trial and get instant access to this article as well as GBA’s complete library of premium articles and construction details. This article is only available to GBA Prime Members Start Free Trial Already a member? Log incenter_img UPDATED on September 18, 2013By now, almost all builders know the importance of installing a water-resistive barrier (WRB) behind siding. Most types of siding leak, so it’s a good idea (and a code requirement) to install a WRB to protect your wall sheathing from any wind-driven rain that gets past the siding.A WRB can be vapor-permeable, like Tyvek, or vapor-impermeable, like foil-faced polyisocyanurate. As long as the wall assembly is designed to dry out when it gets wet, either vapor-permeable or vapor-impermeable WRBs work well.In most cases, WRBs are not air barriers. (The notable exceptions are Zip System sheathing and liquid-applied WRBs.) If you want to create an air barrier on the exterior side of your wall, it usually makes more sense to create the air barrier at the sheathing layer, not at the WRB.Although there are at least six categories of WRB — asphalt felt, Grade D building paper, plastic housewrap, liquid-applied WRBs, rigid foam, and Zip System sheathing — building codes calls for just one: asphalt felt. (One other category — three-dimensional vapor-impermeable barriers — is represented by a single product, Delta-Dry. Although it is often used as a WRB, Delta-Dry has not received code approval as a substitute for code-required WRBs.)In section R703.2, the International Residential Code requires builders to install a layer of number 15 asphalt felt or paperbacked stucco lath over the wall sheathing or studs of every new home. The requirement includes a qualification: if you don’t want to use number 15 asphalt felt, you can use some “other approved water-resistive barrier.”The code requirement calling for walls to be covered with asphalt felt is rather odd, because every asphalt felt manufacturer declares unequivocally that the product is intended for roofs, not walls. When builders install asphalt felt on walls as required by code, the… last_img read more
