Celtic away form as impressive as Liverpool, says Rodgers

first_img0Shares0000Celtic’s manager Brendan Rodgers said he is pleased with the mentality his players have shown in their big games so far in the 2017 season © AFP/File / Christof STACHEGLASGOW, United Kingdom, Oct 26 – Celtic manager Brendan Rodgers says his players showed they have the mentality to handle the big games as they turned on the style in a 3-0 win over nearest challengers Aberdeen on Wednesday.Much had been made of the test Celtic would face from the Dons, with only goal difference separating the sides at the top of the Scottish Premiership before kick-off. However, the Hoops made light work of their hosts with Kieran Tierney’s first league goal of the season giving them a 13th minute lead.The 21-year-old then turned provider for Dembele to tap in his first in the 39th minute before the French striker nodded home a second from close range in the 63rd minute.It was a real show of strength from the Scottish champions which extends their unbeaten domestic run to 61 matches and sends them three points clear at the top.“Tactically they are improving. Over the course of the 16 months we have been here, what I have been pleased with is the mentality in the big games,” Rodgers said of his side.“We’ve got big players who can perform well in big games and they have the confidence to play.“You see it right through from the goalkeeper to the subs bench. They understand how we work, they deal with the pressure of having the ball and they performed exceptionally well.“I think to come to Pittodrie and to play that well where Aberdeen have had 10 days to prepare for the game shows that our boys are continually focused on winning games.”And Rodgers, who previously managed Swansea and Liverpool in the Premier League, hailed the Hoops’ dominant display as one of the best away performances of his managerial career.“Obviously everyone was talking about the pressure of the game between the top teams, so to come away and play with that composure and quality in our game was absolutely fantastic,” the Celtic boss said.“It was an outstanding display against a very good team. I’ve been away with a few teams like Swansea where home and away we were brilliant in terms of our football, and Liverpool as well.“But I feel really proud of the team tonight showing that composure, that level of tactical understanding and their positioning. We should have had five or six goals.“Defensively we were very strong and we virtually gave Aberdeen nothing so I am very proud of the performance.”It was a first defeat of the season for Aberdeen and manager Derek McInnes admitted the match had been tough for him to watch.“We got a lesson and Celtic were very good from the first minute to the last minute,” McInnes admitted.“I actually don’t think whatever system or whatever personnel we went with tonight would have made a difference as when Celtic are in that frame of mind and have that sort of movement then they can do that to any team.”Elsewhere, pressure continues to mount on Rangers manager Pedro Caixinha after Kilmarnock sealed a 1-1 draw following a dramatic finish at Ibrox. Jason Holt gave Rangers a first half lead before Jamie MacDonald saved Daniel Candeia’s last minute penalty.The Gers were reduced to 10 men as Ryan Jack saw red following a scuffle with Killie’s Kirk Broadfoot prior to the penalty being taken before Chris Burke grabbed an equaliser four minutes into stoppage timeThe result sees Rangers drop to fourth following Motherwell’s 1-0 win over Dundee.0Shares0000(Visited 1 times, 1 visits today)last_img read more

Tornado hits disaster center

first_img AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREWalnut’s Malik Khouzam voted Southern California Boys Athlete of the Week A tornado made a direct hit on Henry County’s emergency management center, forcing authorities to relocate to another building to handle the disaster, County Mayor Brent Greer said. The county medical center treated 13 people with injuries, mostly cuts and bruises, hospital spokeswoman Sandra Sims said. The storm also ripped the roof off the main shop at the county highway department, destroyed two smaller shops and damaged a furniture manufacturer next door, Greer said. Most of the highway department staffers were able to take cover in the basement. “We’re very fortunate,” Greer said. Brenda Magee was just arriving for work at the furniture factory when the storm hit. PARIS, Tenn. – Severe thunderstorms rolled across the nation’s midsection late Tuesday, producing funnel clouds that tore off roofs and destroyed or damaged buildings in at least four states. Tornado touchdowns were spotted in 12 counties in western and central Tennessee, with the worst damage apparently occurring in Henry County, about 90 miles west of Nashville. “Numerous homes there were damaged, some completely destroyed,” said Faye Scott, spokeswoman for the Henry County Sheriff’s Department. “It’s major destruction.” Funnel clouds were also sighted in Indiana, Illinois and Kentucky, where one storm-related death was reported. The National Weather Service could not immediately confirm the tornadoes. “We were there for about 10 minutes under tables, dust and everything swirling around,” she said. “It was a big roar. We heard it hit.” Another business, Paris Industrial Services, was destroyed, but none of the employees was hurt. “They told us just to come back tomorrow. We’ll figure out things from there,” employee Chad Fisher said. In neighboring Weakley County, up to seven homes and trailers were damaged or destroyed. The National Weather Service could not immediately confirm the tornadoes. In western Kentucky, storms leveled homes and toppled power lines. At least 22 people were treated for storm-related injuries ranging from minor cuts and bruises to head trauma, according to Jane Barton, a spokeswoman for the Regional Medical Center in Madisonville. In southern Illinois, high winds peeled the roofs off a church and several barns. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

Please try again.subscribeCongratulations! You’re all set! WEST WHITTIER – Los Nietos School District’s newly elected school board member Diana Villalba says she is living proof that every vote does indeed count. Villalba won one of three contested seats on the board – along with Art Escobedo and Grisel Vasquez – by a mere four votes over incumbent Gloria Duran. But the final results came after a stress-filled ballot recount this week that broke an initial Nov. 8 election with Duran at 903 votes apiece. “What a difference a day makes,” she said Thursday. “I got my (school board) certificate today and I’m official! I really feel a lot better now.” Villalba, Escobedo and Vasquez all were sworn in Thursday night. But each has different ideas about where their first official efforts will focus. “You’re going to see some new things with this board,” Escobedo said. “My first official action as a board member will be that I secured food baskets for 100 of the district’s neediest families, working with the Pioneer High School Alumni Association. “That’s never been done before – but these are the kinds of things that we have to do to bring the community together,” he added. Villalba said she would like to work toward restoring band programs at all of the schools because she believes “it’s really important for kids to have music in their lives.” Vasquez, for her part, believes her involvement in after-school sports programs is what earned her votes. “I was very surprised when I found out I’d been elected, and now I feel very honored,” Vasquez said. “Now I want to do the best to fulfill my obligations.” Superintendent Lillian Maldonado French said anytime a new board member is sworn in, “you have a new school board.” “You work to create a cohesion and a bond, and that’s always very important,” French said. “We’re looking forward to that.” tie tracy.garcia@sgvn.com (562) 698-0955, Ext. 3051last_img read more

Science Says Mosquitoes Cannot Fly But Recently Found Out How They Do

first_img(Visited 705 times, 1 visits today)FacebookTwitterPinterest分享0 by Dr Jerry BergmanTo our chagrin, mosquitoes can and do fly, even though scientists have said they can’t. Our response is understandably, “I wish science was true in this case! No one likes mosquitoes.” Actually, scientists have just recently figured out how they are able to fly, and now realize that it involves a very complex designed system. Solving this problem is important because it could have major applications to many other areas of technology, such as designs for micro-scale flying devices. An example is quadcopters, commonly called drones. To produce small micro-drones to fly into very small spaces looking for life, such as in buildings toppled by earthquakes, we need to understand how mosquitoes fly. This technology can then be used to produce micro-drones.Bernoulli Effect. Credit: Miami University of OhioMany animals rely on the Bernoulli effect in order to be able to fly. The Bernoulli effect is the law that fluid pressure falls as the velocity of the fluid movement increases. Thus, the fluid pressure is inversely related to the velocity of the fluid. The Wright brothers discovered this effect by extensive experiments with birds and wind tunnels. They then used what they learned to build their first heavier-than-air flying machine powered by an onboard engine.Airplane wings are shaped to force air to move faster over the top of the wing, causing the air pressure on the top of the wing to decrease. As a result, the pressure on the top of the wing is less than that on the bottom of the wing. The difference in pressure creates lift that literally pushes the airplane upward, at least enough to counter the effects of gravity.This mechanism is used by not only airplanes, helicopters, and birds, but also by most insects – but not mosquitoes, surprisingly. Mosquitoes have small nearly flat planar wings, thus they produce very little lift. For this reason, how they were able to fly has for decades mystified entomologists (biologists who study insects).Scientists solved the mystery of mosquito flight by using both super high-speed cameras and computer analysis.[i] They were then able to “understand the unique mechanisms the insect uses to stay airborne.”[ii] It is only now that science has been able to “explain how mosquitoes managed to flap their wings through such a short angle and still produce enough lift.”[iii] Mosquitoes move their wings around an arc of only about 40 degrees, lower than any other insect group.Credit: Bomphrey/Nakata/Phillips/Walker, Oxford U.Imaging a small creature with large antennae and legs that mask the view of its wings flapping at 800 beats per second, 4 times faster than many other insects of a similar size, was a great challenge. The solution was to use infra-red LEDs, a custom lighting rig, and eight cameras shooting at 10,000 frames per second. The eight cameras were set at difference angles to produce 3-dimensional pictures to help remove the blocking caused by the insects’ antennae and legs.Image credit: Bomphrey/Nakata/Phillips/Walker, Oxford U.The researchers found that mosquitoes use three aerodynamic techniques to fly.[iv] The first is the leading edge vortex that is also used by most other insects. The second and third are a trailing edge vortex and rotational drag, both which, as far as is known, are novel to mosquitoes. Both of these mechanisms rely on subtle, but very precise, wing rotations. The trailing-edge vortex is a type of ‘wake capture’, that requires mosquitoes to align their wings with the air flows they created during the previous wingbeat. The result is they can exploit energy that would normally be lost. For this complex system to function requires not only the hardware, including the wing and neuromuscular design, but also the software, in this case the brain. A major problem for evolution is that, until the entire system was designed and built, mosquitoes could not fly. Consequently, they could not reach their food, which is plant nectar, and, in the case of female mosquitoes that are ready to breed and lay eggs, proteins and lipids—both of which are obtained in animal blood.The common reason mosquitoes bite humans is because when their preferred food source, small mammals, is in short supply, humans are often a target. Mosquitoes become aware of the presence of humans by sensing carbon dioxide (CO2), and the average human exhales more CO2 than most all small mammals. Thus, humans make a bigger impression on a hungry female mosquito’s senses and an easier overall target. The human body also produces strong odor chemicals that, while unpleasant or undetectable to us, are very detectable to female mosquitoes.The design of just the system that allows a small insect to fly is a wonder to behold. It took some of our brightest Oxford University scientists, and the latest technology, to unlock its secret. Nature awaits us with a seemingly endless supply of other wonders yet to be discovered.[i] Richard J. Bomphrey, Toshiyuki Nakata, Nathan Phillips, Simon M. Walker. 2017.

Oxford scientists just solved the mystery of how mosquitos fly using super high-speed cameras. Business Insider, Apr. 19.[iii] Siciliano, 2017.[iv] Mary Beth Griggs. 2017.
