first_imgPAUL Wellens says the team ethic at the Saints will help the likes of Jordan Turner, Willie Manu and Alex Walmsley fit in.At the Club’s recent kit launch he told fans that making sure a player’s family is settled is also vitally important.“It will probably be easy for Jordan, Willie and Alex to settle as they will get on with the lads, come into training and be in that team environment,” he said. “But it’s important we make their partners and children comfortable too. That makes the player’s lives easier and they can then get on with the job.“We have people at the club that make sure this happens.”Wellens is due back in pre-season in the next week or so and has been keeping himself trim since the end of Super League XVII.“I’ve been training and even had a session with Jammer (James Graham) in the gym to get ready for the new season,” he added. “We’re off on a golfing break together soon too.“I’m already looking forward to the new season and the fans are vitally important. There was a lot of anticipation and excitement on moving to a new stadium and it probably took a little while for us all to find our place and create an atmosphere.“We enjoyed playing here and as long as fans keep coming through the doors then that is all that matters.”last_img read more

CHAIRMAN Eamonn McManus has given his thoughts ahe

first_imgCHAIRMAN Eamonn McManus has given his thoughts ahead of Saturday’s Grand Final.Writing in the Manchester Evening News:And so it comes to pass that Nathan Brown’s final game as Head Coach of the Saints will be a Grand Final at Old Trafford against our oldest foe Wigan. The script couldn’t have been written better and the stakes couldn’t be higher.Nathan has done a grand job indeed in his two seasons at the Club and we all sincerely wish him and his family (and it’s a large one!) every luck and best wish in their new lives back home in Sydney.He cast a much needed fresh eye on the squad when he arrived and took some brave and bold decisions both to de-age it and to rebalance it in his first season with us. The facts this season now speak for themselves, winning the league and getting to a Grand Final with a team shorn of its star players in key positions. More importantly he leaves us with a balanced, young, hungry and talented squad who will be competing for honours for many seasons to come.However, our entire focus and energy is aimed at 6pm to 8pm on Saturday and the subject of a new head coach will be put entirely on the back burner until after the Grand Final when a short list of candidates will be considered and interviewed and an appointment made prior to our pre-season in November.It is a record breaking tenth Grand Final appearance for the Saints and, incredibly, our captain Paul Wellens has played in them all. He has four wins and five runners up to date and is desperate to break even and then nudge ahead in October 2015. What a player and what a leader.We are going into the game at Old Trafford on Saturday probably as the biggest underdogs since the advent of Super league, largely due to our injury toll. That does not concern any of us in the very slightest – indeed quite the opposite. We have confidence and we have focus and anyone else’s views are utterly irrelevant.We always know where we stand with Wigan. We really don’t like them and they really don’t like us. It’s a very healthy and balanced relationship actually and all of our lives would be much emptier without it.It will be a titanic encounter and each side will be giving everything and more for their clubs and for their fans. It would be more than a nice touch to see Nathan and Paul lift that Super League trophy, and against all the odds.last_img read more

IT was left to big Ross McCauley to save the U19s

first_imgIT was left to big Ross McCauley to save the U19s blushes with a try five minutes from time which gave the Saints enough of a cushion to hang on 28-18, writes Graham Henthorne.The trouble was by the end the Saints were hanging on in a game which again they had dominated for large periods of the first half but let the opposition back into it through a combination of ill discipline and poor decision making.Never was that more evident than in their first attack of the game when a Danny Richardson bullet pass ricocheted off Olly Davies and the try went begging.The Saints opened their account on the quarter hour when Josh Eaves, making his first proper start for the Saints as an eleventh hour replacement for Aaron Smith who was injured in the warm-up, jumped out of dummy half and went blind. He fed Calvin Wellington and the big Welsh centre jinked his way over in the corner.Great defensive work then gave the Saints the chance to increase their lead. From the start the Saints had been aggressive in defence regularly making it difficult for Rovers to exit their 20 metre area after some great last tackle kicks from Richardson and his half back partner Dave Hewitt. On this occasion the second tackle forced the knock on and from the scrum the ball was passed quickly out to the wing for Dave Eccleston to go over.The Saints continued their dominance but found it difficult to convert pressure into points until the half hour when a great set resulted in a chance for Regan Grace to show his silky running skills. Rick Bailey took a Rovers kick on the full returning it fully 40 metres down the left. Three tackles later and the ball found its way down the opposite wing to Jake Spedding who brought his winger inside giving him a sniff of a gap. Grace duly obliged weaving his way through and around four Rovers defenders to the line.However, the interval saw the game turn on its head and on the back of a bewildering 7 – 1 penalty count the Saints found themselves only six points to the good with 25 minutes to go.Then another piece of Bailey/Grace magic put the Saints in the ascendency again. The full back saved a 40/20 then fed Grace who, as is his wont, charged at the defensive line poking his nose half through. That was enough, however, as he offloaded to the supporting Hewitt who outpaced the cover over 40 metres to the left corner.As ever with Rovers they keep coming at you and were rewarded with a significant piece of luck as from this correspondent’s view a second try was awarded to their prop which seemed to have been dropped from a great height.Four points in it again, the Saints are running out of subs and on empty and the game is on a knife edge. Enter Eaves and McCauley to rescue the day. Firstly the hooker charged down a last tackle clearing kick and luckily managed to gather the ball on the Rovers 20. With all the Rovers team down field for the kick a quick play the ball left big Ross with 20 metres to rung and no-one in front of him. There did seem to be a slight hesitation before he realised that even he could trundle over from there.A win’s a win is an oft used phrase with the Saints at the moment and this match was no different. Plenty tried hard but plenty were either a little dumb in possession or ill disciplined without it.Best of an average bunch was Morgan Knowles who again gave his all this time in a variety of positions.Match Summary:Saints U19s:Tries: Regan Grace, Calvin Wellington, David Eccleston, Dave Hewitt, Ross McCauley.Goals: Dave Hewitt 4.Hull KR U19s:Tries: Chris Smith 2, Aidan Armstrong.Goals: Elliott Kerry 2, Liam Harris.Half Time: 18-0Full Time: 28-18Teams:Saints:20.

KEIRON Cunningham is seeking consistency as Saints

first_imgKEIRON Cunningham is seeking consistency as Saints look to end their regular First Utility Super League season on a high this Friday against Hull KR.After winning their last two games the Champions could return to the top of the table with a win over the Robins.But Cunningham wants another good performance to back up the great victory at Warrington.“We played really well,” he said. “It was a classic Saints-Warrington derby game that went down to the wire. The amount of times we have pinched it in the last minute over Warrington, it probably isn’t funny but as a club we always have that belief that if you hang on in there, no matter how long is left, you will always have a chance.“I was sending messages to the players that we would get an opportunity to win the game in those final stages and when that opportunity arose and we took it.“Warrington attacked really well. They were so quick around the ruck. They had Stefan Ratchford, Brad Dwyer, Daryl Clark, Matty Russell and Richie Myler all coming at us with very quick footwork.“We hung on in there and stopped a lot of tries. That shows the togetherness the players have. They defended like troopers – and deserved the points.“They fought really hard and the way we defended our line was really resilient. We were in the lead for large periods and soaked up the pressure.“The two points were really important. We need to get as many as we can to take into the next phase – and they all help for that final four.“Consistency is important and we have found it this year but only in patches. We started well but then had a lull. I’d like to think we are building once again. We need a good game this week and then take on the challenge we have in the semi-final next week.“Hull KR will come at us at their best. We had a tough time at their place and I’m sure the players are ready for that. Hopefully we can welcome them to Langtree Park like they did to us at their place.“Chris Chester has done a fantastic job there. He had a lot of players come in and has had to gel them in a short period of a pre-season.”Saints will welcome back Atelea Vea into the line-up after he dislocated and broke his shoulder – ironically at the away trip to Hull KR earlier in the season.But Jon Wilkin is out for a few weeks after breaking his thumb.Keiron continued: “I think consistency is important in rugby league and you need that so you can bounce on. I’m not going to tinker but there may be a couple of players rested.“Luke Walsh will play for example – he has been great over the last two weeks and we need him to lead us around the field.“We’ll miss Jon of course. He is a champion of a guy and an ultimate leader for the squad. He doesn’t leave it in the dressing room, he does his talking on the field and runs his blood to water.“I feel for him as he deserves to play in big games. He will bounce back and be back for us sometime in the Super 8s.”Tickets for the game remain on sale at the Ticket Office at Langtree Park, by calling 01744 455 052 or online here.last_img read more

STAR PREVIEW England v Fiji

first_img[dropcap]T[/dropcap]he eighth Rugby World Cup gets underway tonight at Twickenham as England host Fiji (8pm).The 20-team World Cup runs until 31 October and will take place in stadiums across England and at the Millennium Stadium in Cardiff.On three occasions the host country have run out the eventual winners and England will be keen to emulate this year’s favourites New Zealand who won the last tournament which came on home soil for them in 2011.It was last hosted by England in 1991 when Australia beat Will Carling’s England 12-6 in the final.England last went on to win the tournament in 2003 thanks to Jonny Wilkinson’s dramatic drop goal and they are ranked fourth this year.Fiji have only beaten one tier one nation (Italy) in the last eight years and it should be simply a question of how far whether than if England will win. However, Fiji will be boosted by the return from injury from the sensational Nikola Matawalu and come here on the back of a win in the Pacific Nations Cup.This is a tough group for England as they sit alongside Australia, Wales, Uruguay as well as Fiji.A 25 point start for Fiji looks a little over-generous and I will take the 10/11 with Star Sports that they can contain England in what should prove a thrilling start to the tourney.RECOMMENDED BETS (scale of 1-50 points)BACK FIJI (+25) for 10 points at 10/11 with Star SportsRETURN SINCE START OF WORLD CUP: PROFIT 220.36 POINTSWhat’s your view?

The Rice team is laying a theoretical foundation for such structures by analyzing how the blocks’ junctions influence the properties of the desired materials.Rice materials scientist Rouzbeh Shahsavari and alumnus Navid Sakhavand calculated how various links, particularly between carbon nanotubes and graphene, would affect the final hybrid’s properties in all directions. They found that introducing junctions would add extra flexibility while maintaining almost the same strength when compared with materials made of layered graphene.Their results appear this week in the journal Carbon.Carbon nanotubes are rolled-up arrays of perfect hexagons of atoms; graphene is a rolled-out sheet of the same. Both are super-strong and excel at transmitting electrons and heat. But when the two are joined, the way the atoms are arranged can influence all those properties.“Some labs are actively trying to make these materials or measure properties like the strength of single nanotubes and graphene sheets,” Shahsavari said. “But we want to see what happens and quantitatively predict the properties of hybrid versions of graphene and nanotubes. These hybrid structures impart new properties and functionality that are absent in their parent structures — graphene and nanotubes.”To that end, the lab assembled three-dimensional computer models of “pillared graphene nanostructures,” akin to the boron-nitride structures modeled in a previous study to analyze heat transfer between layers.“This time we were interested in a comprehensive understanding of the elastic and inelastic properties of 3-D carbon materials to test their mechanical strength and deformation mechanisms,” Shahsavari said. “We compared our 3-D hybrid structures with the properties of 2-D stacked graphene sheets and 1-D carbon nanotubes.”Layered sheets of graphene keep their properties in-plane, but exhibit little stiffness or thermal conductance from sheet to sheet, he said. But pillared graphene models showed far better strength and stiffness and a 42 percent improvement in out-of-plane ductility, the ability to deform under stress without breaking. The latter allows pillared graphene to exhibit remarkable toughness along out-of-plane directions, a feature that is not possible in 2-D stacked graphene sheets or 1-D carbon nanotubes, Shahsavari said.The researchers calculated how the atoms’ inherent energies force hexagons to take on or lose atoms to neighboring rings, depending on how they join with their neighbors. By forcing five, seven or even eight-atom rings, they found they could gain a measure of control over the hybrid’s mechanical properties. Turning the nanotubes in a way that forced wrinkles in the graphene sheets added further flexibility and shear compliance, Shahsavari said.When the material did fracture, the researchers found it far more likely for this to happen at the eight-member rings, where much of the strain gathers when stressed. That leads to the notion the hybrids can be tuned to fail under particular circumstances.“This is the first time anyone has created such a comprehensive atomistic ‘lens’ to look at the junction-mediated properties of 3-D carbon nanomaterials,” Shahsavari said. “We believe the principles can be applied to other low-dimensional materials such as boron nitride and molybdenum/tungsten or the combinations thereof.”Shahsavari is an assistant professor of civil and environmental engineering and of materials science and nanoengineering at Rice.Rice University, the National Science Foundation (NSF), the National Institutes of Health and IBM-shared University Research Award supported the research. The researchers used the NSF-supported DAVinCI supercomputer administered by Rice’s Ken Kennedy Institute for Information Technology.-30-Read the abstract at http://www.sciencedirect.com/science/article/pii/S0008622315302086Follow Rice News and Media Relations via Twitter @RiceUNewsRelated Materials:Shahsavari Group: http://rouzbeh.rice.edu/default.aspxGeorge R.
