With roster intact OSU meets lofty expectations as season arrives

For the first time since 2005, the hype surrounding the Ohio State men’s basketball team has nothing to do with incoming freshmen. It has nothing to do with recently departed stars and nothing to do with “what could have been.”The Buckeyes, who had become all too familiar with players leaving early for the NBA, return all but one player from last year’s team and have zero incoming freshmen.The focus on this team is not on the talent leaving Columbus, but rather on the talent staying in town.A sense of continuity is something that has been absent from the program since 2006, when Greg Oden began a trend of “one-and-done” players making short stays at OSU. The team’s familiarity with one another is something coach Thad Matta knows is important. “Repetition builds confidence in my mind,” Matta said. “I think that’s the beauty of seeing guys that have been in the program for more than one or two years. Now, there’s not a lot that they’re going to see that’s going to be new to them.”Even though the season has yet to begin, Matta said he has already noticed an improvement in his team’s ability to recognize certain situations on the court — a recognition that, because of the youth of his previous teams, was not there in the past.“These guys have played a lot of basketball together,” Matta said. “They’ve got a pretty good feel for what other guys can do. So, from that standpoint, that carries some clout for us.”Getting healthyBoth David Lighty and Nikola Kecman return this year after seeing their previous season cut short because of injury.Kecman, a sophomore, played in only one game last season before tearing his ACL in practice.Lighty, who broke his foot in the team’s seventh game last season, is now a redshirt junior coming into his fourth year at OSU. He is considered by many on the team to be the Buckeyes’ vocal leader and will make his biggest impact on the defensive end.“Dave is a great player and a great leader,” senior Kyle Madsen said. “One of the best things he does is play defense and talk on defense. He’s a really loud guy who brings everyone together.”Though it was difficult for him to watch from the bench last year, Lighty said it was his absence that allowed for others to gain valuable experience.“I dropped off and everyone stepped up their game and came ready to play,” Lighty said. “It’s going to be really good for us.”As Lighty and Kecman make their returns, junior Dallas Lauderdale will fill the vacancy on the injury report. Lauderdale, who was projected as the Buckeyes’ starting center, broke a bone in his hand during a preseason practice and is not expected to be healthy in time for the season opener.He will be replaced by senior Kyle Madsen and sophomore Zisis Sarikopoulos until he is able to return.Buckeyes begin season nationally rankedFor just the second time in Thad Matta’s career in Columbus, the Buckeyes found themselves ranked in the preseason Top 25.OSU begins the season at No. 16 in the preseason AP Poll and is one of six Big Ten teams ranked by the AP to start the year.The Buckeyes are No. 17 in the Coaches’ Poll, one of five Big Ten teams ranked in the Top 25.Matta’s first OSU team to be ranked at the start of the year entered the 2006-07 season ranked as high as fourth. The Buckeyes went on to win both the Big Ten regular season and tournament championships, and finished as the national runner up.Turner earns preseason All-Conference honors; team projected to finish thirdJunior Evan Turner, who averaged a conference-best 17.3 points per game a season ago, was named the preseason All-Big Ten team by the media.Turner, Purdue’s Robbie Hummel, Penn State’s Talor Battle, Michigan’s Manny Harris and Michigan State’s Kalin Lucas, all juniors, were tabbed as the conference’s best players headed into the season.Lucas, the reigning Big Ten Player of the Year, was projected by the media to retain the title, and was named the Preseason Player of the Year.Likewise, Lucas’ Spartans are projected to repeat last year’s regular season conference championship. The Buckeyes, who finished last year in a tie for fourth in the conference, are projected to finish third, behind Michigan State and Purdue. Roller coaster non-conference scheduleBefore beginning Big Ten play at the end of December, the Buckeyes will play 12 teams from out of conference, nine of which will be played at home.The Buckeyes’ non-conference home schedule doesn’t look to be much of a challenge.The home schedule includes only one team from a major conference in Florida State, and is filled with the likes of Lipscomb and Cleveland State, among others.Away from Columbus, however, the Buckeyes will be put to the test.OSU will play both North Carolina and either California or Syracuse as a part of the 2K Sports Classic in New York City. Along with a trip to Indianapolis to play Butler, the Buckeyes will be pitted against three teams ranked in the preseason Coaches’ Poll Top 25.“With the schedule like that you have a chance to play teams from other conferences that are high powered and that we may meet in the NCAA tournament,” senior P.J. Hill said.“[After our non-conference games] we’ll know where we stand as a ball club and as individual players so I think that’s going to be a great test for us.”The Buckeyes begin play Wednesday with an exhibition game against Walsh before getting the season officially underway Monday against Alcorn State. read more

Mens Soccer Buckeyes head home to take on Northwestern trip to Ann

Ohio State men’s soccer head coach Brian Maisonneuve watches the Buckeyes play in the first half of the game against the University of South Florida on Sept. 7, 2018. Credit: Casey Cascaldo | Photo EditorComing off a 3-1 defeat at Penn State to open its Big Ten schedule, the Ohio State men’s soccer team (1-5-1) returns home to take on Northwestern on Friday. The Buckeyes have scored goals in consecutive games, following a three-game scoreless drought and will need the momentum to continue against a tough Northwestern squad.Ohio State’s first year head coach Brian Maisonneuve said Northwestern’s depth is a major concern.“They got it rolling. They’re organized, they’re talented, they’ve got some new pieces,” Maisonneuve said. “Some of the freshmen stepped up and are doing a really nice job, and then they’ve got a lot of returners, so they’ve got some experience.” The Wildcats (4-2-1) are anchored by solid play in all facets of the game. Sophomore goalkeeper Miha Miskovic owns a 0.67 goals against average this season, which is good for 28th best in the nation. On the offensive end, the Wildcats are led by senior midfielder Camden Buescher and freshman midfielder Bardia Kimiavi. Buescher has scored three goals, while Kimiavi has scored two. Four other Wildcats have also scored this season. “They’re playing some really good soccer right now, so it’s definitely going to be a challenge,” Maisonneuve said. Maisonneuve also said that while the goals are starting to come, he doesn’t like that they gave up three goals the last time out and says his team will need to tighten things up defensively. “We were creating chances the whole year, sometimes it just takes a little bit to find the back of the net,” Maisonneuve said. “A lot of times when you have a new group, new tactics and just everything’s brand new, we’re looking at five weeks now, sometimes that final piece is the goal-scoring piece.”Friday’s match comes just days ahead of a trip to Ann Arbor to take onl Michigan. Redshirt senior midfielder Brady Blackwell knows that they cannot look past Northwestern, and they will have to take things day by day, game by game if they want to be successful. “Northwestern’s a good team, they’ve got some good wins this season, so right now we’re looking to build off Friday and take that into Michigan,” Blackwell said. “If we can get a good win on Friday, that’ll give us a lot of momentum going into Ann Arbor.” The Buckeyes will have to excel in all areas of the game on Friday if they want to knock off Northwestern to claim their second victory of the season. Friday’s game is scheduled at Jesse Owens Memorial Stadium for a 7:30 p.m. start. Following Friday night’s match, the Buckeyes will travel to face No. 21 Michigan on Tuesday. read more

Redknapp insists Lampard should be proud

first_imgFormer Liverpool midfielder Jamie Redknapp insists Derby County manager Frank Lampard should be proud of his team’s display against Chelsea.The Rams put in an excellent display, coming back from a goal down on two separate occasions during their 3-2 loss to the blues in the Carabao Cup on Wednesday night.Defenders Fikayo Tomori and then Richard Keogh both scored own goals, but Derby twice bounced back with goals from Jack Marriott and Martyn Waghorn, and they even had good chances late in the game, to extend the tie to penalties.“There were a couple of big moments at the end when Richard Keogh and David Nugent nearly scored, but he will be so proud of his team with the way they played and the way they passed the ball,” Redknapp told Sky Sports.Frank Lampard, Chelsea, Premier LeagueFrank Lampard admits Chelsea may struggle for top-six spot Andrew Smyth – September 14, 2019 Chelsea manager Frank Lampard couldn’t offer any guarantees on a top-six finish this season due to the strong competition.“He would have learned a lot about them today and they have come so far in a short spell under him. I thought they played really well today.”“They have got players who showed they will be more than capable of holding their own if they come up to the Premier League. But now they have gone out and they can concentrate on the Championship, which is what is so important now.”“Frank will be devastated that they have lost the game but now they can have a rest and go again in the league. The aim is to come up and play in the Premier League.”last_img read more

Ritchie Newcastles win over Man City could be a turning point

first_imgNewcastle United defender Matt Ritchie is hoping that their 2-1 win over Manchester City can prove to the catalyst that turns their season around.The Magpies seemed set for a 13th Premier League defeat this term after Sergio Aguero handed City the lead at St James’ Park in the opening 24 seconds of the match.But Newcastle held their nerve in front of the home crowd to mount a stunning comeback which saw Venezuelan striker Salomon Rondon equalise in the 66th-minute.Ritchie then scored the match-winner for Newcastle after Sean Longstaff was fouled in the area by Fernandinho.The 2-1 win over reigning champions City moves Newcastle up to 14th-place in the Premier League and, crucially, five points above the drop zone.Now Ritchie hopes they are back on track after securing back-to-back wins in the league for only the second time this season.“The place has been low, to be honest. The players have kept believing, we keep training, keep focused,” Ritchie told BT Sport.“It’s a fantastic result. The main thing was belief, I’m not sure many people thought we could win the game, but certainly, in the dressing room we did.Harry Maguire, Manchester UnitedLiverpool legend Nicol slams Harry Maguire’s Man United form Andrew Smyth – September 14, 2019 Steve Nicol believes Harry Maguire has made some “horrendous mistakes” recently, and has failed to find his best form since joining Manchester United.“It was a kick in the teeth to concede so early. To get in at 1-0 at half-time was good. We regrouped.“We have belief within the group that we can still have a good season.“We beat Man United at home last season and that was the turning point, hopefully, this can be the turning point this year.“Just belief and togetherness in the group, we need the people around to believe as well. Hopefully, that gives everyone hope.”Newcastle manager Rafael Benitez also gave his thoughts on the victory in which he expressed his delight at how his side stuck to their game plan, despite the early setback.Next up for Newcastle will be a trip to Wembley to take on Tottenham on Saturday in the Premier League.last_img read more

Best Buy To my thinking, any TV you buy today should have either Amazon Fire TV or Roku built in. Thankfully, you don’t have to pay a premium for those awesome “smart” interfaces.Proof positive: Today only, and while supplies last, Best Buy once again has the Insignia 32-inch LED TV with built-in Fire TV for just $99.99 (plus tax). That’s $70 off the regular price, and a repeat of a sale from about a month ago.See it at Best BuySo, Fire TV or Roku? The latter gets more attention these days, but Fire TV is arguably just as good and may be even better. It affords most of the same streaming apps: Netflix, Hulu, HBO and so on. (Alas, if you want YouTube, you have to access it via a web-browser app.) And it comes with an Alexa-enabled remote, so you can bark orders at the TV.Fire TV also affords access to various Alexa skills and a huge library of Amazon apps.

Mayor Turner And Greater Houston Partnership Lead Trade Delegation To Mexico City

first_imgListen 00:00 /01:18 Mayor Sylvester Turner’s Twitter accountHouston Mayor Sylvester Turner (right) and Mexico City’s Mayor Miguel Ángel Mancera (left) met during the delegation’s trip to the neighboring country.This week, Houston Mayor Sylvester Turner and the Greater Houston Partnership (GHP) are leading a trade delegation to Mexico City.More than 1,000 companies across greater Houston report doing business with Mexico and in 2015 that trade was valued at more than $17 billion, according to Mayor Turner’s office.The delegation is focusing on strengthening the relationship in terms of tourism and medicine, with potential agreements between the Texas Medical Center and some Mexican hospitals.But energy is certainly also on the agenda and the mayor notes that the World Petroleum Congress will soon be voting on where the conference will be held in 2020.“It has not been in the United States, and specifically in Houston, in the last 30 years. Mexico has a vote at that conference next month and I am asking for their support for the City of Houston,” Turner told Houston Public Media.The trip coincides with the Monday Night Football game being played in Mexico City between the Houston Texans and the Oakland Raiders.Bob Harvey, president and CEO of the GHP, underlined that they planned the trip around the football game because “it was just the perfect opportunity to bring a larger than typical delegation to Mexico City.”The delegation also includes representatives from the Houston Airport System and the Port of Houston, as well as several companies that have offices in our city.They will meet with top officials from the Mexican government, and with Mexico City’s Mayor Miguel Ángel Mancera, among others.

Researchers uncover amazing physics feat of spitting Archerfish

first_img © 2013 Phys.org Play Low-resolution color movie showing an archer fish shooting a jet of water to a prey supported by a clear plastic film. During the shooting the mouth of the fish barely emerges from the interface between water and air, while the rest of his body remains submerged. The image sequence has been grabbed at 400 frames/s and is played at 25 fps. Credit: doi:10.1371/journal.pone.0047867.s001 All in all, it’s an amazing use of math and physics—all by a fish with barely any brains. Watching Archerfish in action, most would likely be impressed at the way they catch their food. They move to just below the surface then shoot a mouthful of water into the air. The water eventually reaches an insect perched on a branch or blade of grass and knocks it into the water. As the water is inflight, the fish is already on the move, positioning itself to where it knows the insect will land. Then it eats it.Vailati and his colleagues can’t explain how the fish is able to calculate the proper trajectory of its water blob, or how it knows when and where to position itself, but they are able to explain why the water expulsion technique the fish uses, is so successful. It comes down to principles of Physics.To start things off the researchers filmed the fish—slowing down the action to see what was happening. They discovered what seemed impossible—that the water was actually accelerating as it headed towards its target. Further investigation revealed how it was possible.First off, the fish pushes the water out harder the longer its spurt lasts. This means that the water at the tail end of the blob of water is moving faster than the water at the leading end. That would normally mean the water blob would flatten as it ran into itself and spread out. Not in this case, instead the fish uses a known fluid dynamics property called the Plateau–Rayleigh instability. This is where water moving as a stream brakes down into small pieces—small segments form and are eventually pinched off to create entirely separate, much smaller blobs, of liquid, all moving in the same direction as the original stream. So, because the tiny blobs are separated, the original blob doesn’t bunch up as it travels. But, then it does, as the tiny blobs in back catch up with the ones in front, just before it hits the targeted insect, knocking it, violently off its perch and into the water below.

Vailati et al report in a paper they’ve had published in the journal PLoS ONE, that the fish actually cause a mouthful of water they expel, to speed up, as it travels through the air on its way to its target. More information: Vailati A, Zinnato L, Cerbino R (2012) How Archer Fish Achieve a Powerful Impact: Hydrodynamic Instability of a Pulsed Jet in Toxotes jaculatrix. PLoS ONE 7(10): e47867. DOI: 10.1371/journal.pone.0047867AbstractArcher fish knock down insects anchored to vegetation by hitting them with a precisely aimed jet of water. The striking force of the jet at the impact is such to overcome the strong anchoring forces of insects. The origin of the effectiveness of such hunting mechanism has been long searched for inside of the fish, in the unsuccessful attempt to identify internal structures dedicated to the amplification of muscular power. Here we perform a kinematic analysis of the jet emitted by two specimens of Toxotes jaculatrix. We estimate that at the impact the jet conveys a typical specific power of about 3000 W/kg, which is well above the maximum specific power of the order of 500 W/kg deliverable by a vertebrate muscle. Unexpectedly, we find that the amplification of muscular power occurs outside of the fish, and is due to a hydrodynamic instability of the jet akin to those occurring in Drop-on-Demand inkjet printing. The investigated fish are found to modulate the velocity of the jet at the orifice to favor the formation of a single, large, water drop that hits the prey abruptly with a large momentum. The observed mechanism represents a remarkable example of use of an external hydrodynamic lever that does possibly not entail the high evolutionary cost needed for the development of highly specialized internal structures dedicated to the storing of mechanical energy.via Wired Citation: Researchers uncover amazing physics feat of spitting Archerfish (2013, December 3) retrieved 18 August 2019 from https://phys.org/news/2013-12-uncover-amazing-physics-feat-archerfish.htmlcenter_img Explore further Journal information: PLoS ONE Archer fish hunt insects with water jet 6 times stronger than their muscular power This document is subject to copyright.

3C 17 is a member of a newly identified galaxy cluster observations

first_img Radio galaxies emit huge amounts of radio waves from their central cores. Black holes at the center of these galaxies are accreting gas and dust, generating high-energy jets visible in radio wavelengths, which accelerate electrically charged particles to high velocities. Radio galaxies are observed to interact with their environment in often spectacular ways. For instance, in some of them, jets emanating from the central black hole are bent due to supersonic ram pressure of the intracluster medium.At a redshift of 0.22, 3C 17 (also designated PKS 0035–02) is a broad-line radio galaxy showcasing strong indications of interaction with its environment. Previous observations of this galaxy found that its radio morphology is dominated by a single-sided, dramatically curved jet.The remarkable morphology of 3C 17’s radio jet, and several unclassified sources along the jet’s path, motivated a group of astronomers led by Juan P. Madrid of Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia, to perform further studies of this galaxy. As part of their research, the team conducted observations of 3C 17 using the Gemini Multi Object Spectrograph (GMOS) of the Gemini Observatory, and analyzed observational data of this galaxy provided by NASA’s Chandra X-ray spacecraft.”An optical and X-ray study of 3C 17 and its environment was carried out using Gemini and Chandra data,” the researchers wrote in the paper.The observations allowed Madrid’s team to identify a previously uncatalogued cluster of galaxies at a redshift of 0.22, with a projected virial radius of about 1.2 million light years, and a velocity dispersion of around 821 km/s. They found that 3C 17 belongs to this cluster and that with an absolute magnitude of –22.45 it is the brightest cluster member. Furthermore, the study also revealed that 3C 17 is dominated by broad emission lines.”Its surface brightness profile is best fit with a double component model characteristic of BCGs [brightest cluster galaxies],” the paper reads.Moreover, based on the analysis of Chandra data, the scientists uncovered the presence of extended soft X-ray emission surrounding 3C 17. They assume that this emission most likely has its origin in the hot gas of the intergalactic medium.In concluding remarks, the authors of the paper say that 3C 17’s membership in a galaxy cluster explains its radio morphology. They noted that the jet of this galaxy is sharply curved as it propagates through a dense intracluster medium.The researchers added that bent-tail radio galaxies like 3C 17 could be used by astronomers as signposts for distant galaxy clusters in wide-field radio-continuum surveys to be conducted in the future. Using the Gemini Observatory and NASA’s Chandra spacecraft, a team of astronomers has provided new information about the radio galaxy 3C 17 and its environment. The observations show that 3C 17 is the brightest member of a newly found galaxy cluster. The finding is reported in a paper published October 18 on arXiv.org.
