A restructure of the sport in Australia has resulted in the affiliates (local competitions) becoming direct members of the national body. The new structure, recommended by an independent report produced in June 2004, is being implemented across Australia. Chief Executive of TFA, Kevin Thompson, said today “It is great to see that the local competitions appreciate the benefits of the new model and are signing up. The whole theme of the restructure is to reduce duplication and administration and to divert more resources to the grass roots. The players, officials and coaches in BMTA and Berserkers will be the first to benefit.” Keep an eye on the website for the upcoming full story and all the latest info on the Unitary Model of Management and Affiliation with Touch Football Australia. * The Queensland All Schools Championships have attracted a record 198 teams…make sure you keep an eye on the website this week, we’ll be talking to Queensland School Sport legend Peter Bell about the upcoming event. * Remember, results from the Under 18’s will be updated at the end of every round throughout the tournament, make sure you keep checking the website regularly.

Wickets in England to assist batsmen Sachin

first_imgMumbai: Batting great Sachin Tendulkar reckons that the wickets in England and Wales, set to host the 2019 Cricket World Cup starting May 30, will assist batsmen and bowlers might struggle to swing the ball. Sachin said the summer conditions, which will prevail during the showpiece event, will not help bowlers much and the pitches will behave in a similar way as during the 2017 Champions Trophy in England. “I am told it’s going to be a hot summer. Even during the Champions Trophy the wickets were superb when the sun was out. In the heat, the wickets get really flat. I am sure they will give beautiful tracks to bat on,” the 46-year-old said on the sidelines of the inauguration of the MIG Club pavilion named after him.

If there is a cloud cover, the ball might go around a bit. Even if that’s the case, I don’t see that happening for a longer duration, may be just in the initial overs,” he said. Sachin also felt as several Indian players, including captain Virat Kohli, M.S. Dhoni, Hardik Pandya and Shikhar Dhawan, are performing well in the ongoing Indian Premier League (IPL), it will help in boosting their confidence for the World Cup. “A good performance in any format is good news because it gives the player confidence. If you are confident, that’s important,” he said. “The players have time to make some adjustments according to the conditions. All of them have played enough cricket to know what to do to improve,” Sachin remarked.last_img read more

Tajh Boyd Leads No 3 Clemson over NC State

Quarterback Tajh Boyd and the Clemson Tigers football squad was victorious over N.C. State Thursday night.In his first Atlantic Coast Conference game of the year, the star QB threw three touchdowns for 244 yards to help his team beat the Wolfpack 26-14.Clemson’s offense has been on fire since the beginning of the football season. The Tigers came in averaging 45 points and 490 yards a game, but didn’t manage to score a TD until the end of the second quarter.“We had two or three scoring opportunities that we didn’t convert on and just missed them. Just that simple,” Clemson coach Dabo Swinney said. “I thought we had a good game plan. I was pleased with how we were able to run the ball but disappointed with some execution in the first half. … But we cleaned it up, we battled hard and got it to the second half and we ended up coming alive.”Boyd praised his teammates for overcoming earlier struggles to still win the game.“I think for the offense we always go and find a way to make a play when it’s needed,” Boyd said. “When we really need it, we go get it done. … It was huge. We had to make sure we got something out of it.” read more

Ohio States Storm Klein reinstated

Formerly-dismissed Ohio State linebacker Storm Klein has been reinstated to the Buckeyes’ football team. OSU spokesman Jerry Emig confirmed in an email that first-year coach Urban Meyer has let the senior back on the squad, though “he will not be allowed to play in a game until at least the third week of the season.” “As I had indicated previously, if there are any changes in the charges against Storm, I would re-evaluate his status,” Meyer said in a released statement. “The charges that would have violated our core values have been totally dismissed. I have spoken extensively to members of both families and that has prompted me to re-assess his situation and allow him back.” According to Franklin County Municipal Court records Klein pleaded guilty to misdemeanor disorderly conduct Monday morning having originally faced charges for domestic violence and assault. Klein was arrested late on July 6 after allegedly striking the mother of his child. A day later, Meyer dismissed the linebacker from the team and said in a released statement that the charges against Klein “violate the core values of the Ohio State football program.” Meyer, though, said, “If there are any changes in the charges” he would re-evaluate Klein’s status with the program. On Wednesday, Klein’s lawyer, Larry James, confirmed to The Lantern that both the domestic violence and assault charges were indeed dismissed. All that Klein faces now, he said, is 18 months of probation and court fees. If Klein has been reinstated, James added that Meyer told him any infraction “whatsoever” could still result in a penalty to pay. In his three years on the field, Klein has amassed 73 tackles in 38 games for the Buckeyes, including 45 in 2011. Before his dismissal, Klein was not listed as a starter on OSU’s depth chart. read more

Lady Buckeyes lose to North Carolina 5754

Like the men’s team, Ohio State’s women’s basketball team made a trip to the “Tobacco Road” portion of the state of North Carolina. They will bring a loss home. The No. 15-ranked Buckeyes were unable to win on the road in their visit to No. 22 North Carolina, falling short to the Tar Heels, 57-54. With the loss OSU falls to 4-2 on the season. Both of their losses have come against ranked opponents. OSU senior guard Tayler Hill scored a game-high 24 points on 9-21 shooting led OSU, but the Buckeyes’ likely could have used another scoring option as no other player reached double figures. Conversely, three different Tar Heels scored 11 points in the game. It was a close contest, but the Buckeyes had to claw their way back from a large deficit to make it a game. Midway through the second half, OSU trailed by 16 points at 44-28. With Hill leading the way the Buckeyes were able to cut the margin, and even took a two-point lead with 1:26 left to play. But the Tar Heels answered in a big way, forcing two turnovers down the stretch and scoring the game’s final five points to clinch the upset win. OSU returns home this weekend for a noon tipoff against Evansville. read more

Womens Basketball Strong third quarter pushes No 16 Ohio State to 8869

Ohio State senior guard Kelsey Mitchell (3) dribbles past defenders in the second quarter against Michigan State on Jan. 27 at the Schottenstein Center. The Buckeyes beat the Spartans 78-62. Credit: Alyssia Graves | Assistant Sports DirectorAfter coming off of a brutal loss in which Ohio State let South Florida junior guard Kitija Laksa drop 41 points on it in an 84-65 loss, the team’s main focus was to bounce back — and bounce back it did.No. 16 Ohio State (21-6, 10-3 Big Ten) went on the road and beat Illinois (9-18, 0-13 Big Ten) by a commanding score of 88-69. The Buckeyes received a lot of production from senior guard Kelsey Mitchell and redshirt senior Linnae Harper. Mitchell finished with 28 points, while Harper added a double-double with 20 points and 11 rebounds.Ohio State’s strong third quarter proved to be the difference maker. After a rough end to the first quarter and strong second quarter, Ohio State finished the third quarter outscoring Illinois 28-15. Heading into the fourth quarter, Mitchell had 21 points with the Buckeyes up 66-48.The Buckeyes came out of the gates strong, quickly jumping out to a 13-4 lead to start the first quarter thanks to a couple of Mitchell 3-pointers. That lead quickly disappeared when Illinois closed out the quarter on a 17-3 run to take a 21-16 lead after one quarter. The Buckeyes again jumped out to a strong start in the second quarter to regain a double-digit lead. However, Illinois clawed its way back into the quarter and made its halftime deficit a manageable seven points, 38-31. Ohio State’s lead at the break would have been larger had Illinois junior forward Alex Wittinger been held in check. Heading into the second half, Wittinger had 18 points on 8-for-13 shooting with eight rebounds. Wittinger finished with a double-double, 30 points and 16 rebounds.After the third quarter, the Buckeyes cruised the rest of the way. Illinois trailed significantly while Mitchell continued to drain basket after basket in the fourth. After going down 21-16, the Buckeyes outscored Illinois 67-53 the rest of the way.With three games remaining in conference play, Ohio State will look to close out the regular season strong heading into the Big Ten Tournament. It returns home to face Purdue for Senior Night at 1 p.m. Saturday at the Schottenstein Center. read more

Review England – Belgium

first_imgWith a moment of individual brilliance, Adnan Januzaj gave Belgium a 1-0 victory and the first place in Group G.The final two matches of the group stage are soon upon us…Here are the teams for #ENGBEL!#ENG #BEL pic.twitter.com/rvom0sQ4Ru— FIFA World Cup (@FIFAWorldCup) June 28, 2018Januzaj tips United to return to the top Obinna Echi – November 14, 2018 Adnan Januzaj has backed his former club Manchester United to start challenging for the Premier League title soon.Januzaj believes United need to make the…Even though first place was up for grabs, both Gareth Southgate and Roberto Martinez decided to make multiple changes to their starting lineups today in Kaliningrad. There was no Harry Kane, no Eden Hazard, no Romelu Lukaku and no Kevin De Bruyne. The lack of star power didn’t mean the fans weren’t still hoping to see an entertaining encounter.A defensive lapse allowed England to have a moment in the opening two minutes that ended with Courtois blocking a cross before it came to Jamie Vardy. Youri Tielemans blasted a long-distance strike in the 7th minute, catching Jordan Pickford a bit asleep. Luckily for England’s goalkeeper, the shot was in the middle of the net, so he made the save. A couple of minutes later, Adnan Januzaj made a few dribbles and then lobbed a cross that came to Mitchy Bashuayi. He headed the ball back towards the central area in front of Pickford and even though there wasn’t a distinct shot, the ball rolled towards the goal line before Gary Cahill cleared it just before it went in.Tielemans received the game’s first yellow card. In this contest, cards were particularly important, as they could determine the final standings in case of a draw. With this card, Belgium had two more than England overall. Another foul on Danny Rose earned Belgium’s second booking. This time the guilty party was Leander Dendoncker. Whistles were coming from all over the stadium. The fans weren’t happy. The Belgian defensive trio was passing the ball among each other, while the English players refused to press. It was more than obvious both teams were satisfied with the current situation.Gareth Southgate decided to save his main defender’s energy and replaced John Stones with Harry Maguire at the half. In the 51st minute, Adnan Januzaj’s individual brilliance gave The Red Devils a 1-0 advantage. He dummied Danny Rose and then curled a beautiful left-footed shot, leaving Pickford with no choice but to take the ball out of his net. Belgium took over first spot in Group G with the goal. Later on, Thomas Vermaelen suffered a cut on his eyebrow after an aerial duel with Jamie Vardy. Marcus Rashford missed from an ideal one-on-one situation with the goalkeeper in the 66th minute. What a miss! Courtois got a touch on the ball, but it doesn’t change the fact that if Rashford wants to be considered as a starter, he must not miss those types of opportunities.Roberto Martinez decided to give the recently recovered Vincent Kompany a run, taking off Vermaelen to make place for the experienced center back. The next swap was Danny Welbeck for Trent Alexander-Arnold, signalling a wish to tie the game. Although, based on the play, that wish was really weak. On the other hand, why would England try to earn a draw? Losing this match meant a meeting with Colombia (possibly without James Rodriguez) in the Round of 16 and then (potentially) either Switzerland or Sweden in the quarter-finals. It also meant avoiding Brazil, as well as the other superpowers in the top part of the draw. Pickford saved Dries Mertens’ effort in the 89th minute. Marouane Fellaini missed in the 92nd minute and that was it. Belgium won for the third time in three matches, finished first with 9 points and will meet Japan next.last_img read more

Immigration Authorities Cite Fewer Serious Crimes In Deportation Paperwork

first_img Listen Nationally, only 2.8% of recent deportation-related filings were based on alleged criminal activity.The TRAC report also shows that nationally, criminal activity as a reason for deportation has dropped in half in the last five years.Syracuse University’s Transactional Records Access Clearinghouse (TRAC)“Where previous administrations had focused on people with criminal convictions, the natural, logical conclusion is a higher percentage of people were going to be those without criminal convictions, because they are just picking up everybody,” said Houston Immigration Legal Services Collaborative deportation defense attorney Julie Pasch.In January 2017, the Trump administration did away with immigration enforcement priorities that encouraged Immigration and Customs Enforcement (ICE) to target dangerous criminals for removal. “Under the Trump administration there are a new set of priorities and essentially anyone [in the country without documentation] is a priority now,” said Susan Long, director of Syracuse University’s TRAC research center.However, just because a serious crime isn’t cited, doesn’t mean someone didn’t commit a crime, according to Pasch. Sometimes prosecutors list a lesser immigration offense because it’s easier to prove, she said.  00:00 /00:54 X U.S. Immigration and Customs EnforcementU.S. Immigration and Customs Enforcement arrest company employees on federal immigration violations at a trailer-manufacturing business in Sumner, Texas.Serious crimes are showing up less and less in deportation paperwork filed by federal officials, according to new data from Syracuse University’s Transactional Records Access Clearinghouse (TRAC). Serious criminal activity was cited in 3% of 24,000 deportation-related court filings in the Houston area over the last nine months, including data from immigration courts in Conroe and Houston. center_img Share To embed this piece of audio in your site, please use this code: last_img read more

Radioactive isotope of tin confirmed to have doubly magic nucleus

The content is provided for information purposes only. Citation: Radioactive isotope of tin confirmed to have doubly magic nucleus (2010, May 28) retrieved 18 August 2019 from https://phys.org/news/2010-05-radioactive-isotope-tin-doubly-magic.html Protons and neutrons in nuclei occupy orbital shells in a similar way to electrons in atoms. Nuclear magic numbers were first identified in 1948 by Maria Goeppert-Mayer, who shared in the 1963 Nobel prize for physics for her work on developing the nuclear shell model. Nuclear magic numbers are the numbers of nucleons (protons or neutrons) that form full (closed) outer shells in an atomic nucleus, like the magic numbers of electrons in helium, neon and other noble (super-stable) gases. The magic numbers for nuclei are 2, 8, 20, 28, 50, 82, and 126, while for electrons the magic numbers are 2, 8, 18, 32, and 50.Magic proton or neutron numbers give the nucleus greater stability and stronger binding, and are therefore usually more common than nuclei with unfilled orbital shells. In doubly magic nuclei both proton and neutron shells are filled, leading to even stronger binding and stability. The outer shells of doubly magic nuclei are rigidly spherical.Other confirmed doubly magic nuclei include helium-4, oxygen-16, lead-208, calcium-49, and nickel-48, which are abundant and stable, and nickel-56, which was discovered in 1998 and is less stable than the others, having a half-life of just 5.9 days. Tin-132 is even more unstable with a half-life of only four seconds, which has made confirmation of its doubly magic nature difficult. It has 50 protons and 82 neutrons, and is the first confirmed doubly magic isotope that is both neutron-rich and radioactive.Kate Jones, from the Department of Physics and Astronomy at the University of Tennessee in Knoxville, Tennessee, and her colleagues used a cyclotron reactor at the Oak Ridge National Laboratory dating from the 1950s to carry out the experiments. Jones said they were excited to have managed the feat, when most people thought it would not be possible until newer facilities were available.One method used to identify doubly magic nuclei has been to strip neutrons from the isotope and examine the properties of the stripped-off neutrons to infer the structure of the nucleus. To do this a film is made of the isotope in question, and this is then hit with a beam of deuterium (an isotope of hydrogen having one proton and one neutron).Tin-132’s extremely short half-life made this process impossible, so Jones and her team reversed it, using the isotope as the firing beam instead of as the film being hit. They accelerated a beam of tin-132 to about 10 percent of the speed of light and fired it at a target of deuterated polyethylene. As the tin-132 collides with the target some of the neutrons are stripped from the deuterium molecules to form tin-133, leaving the deuterium proton to fall back to the target. The researchers then analyzed the energy and angular distribution of the particles and were able to confirm the stripped neutron fell into a separate orbital shell above the closed inner shells of tin-132, which means the nucleus must be robustly spherical as expected for a doubly magical nucleus.The research findings will help physicists studying what is called the R-process, which is thought to be the process by which over half the elements heavier than iron are created through a series of neutron captures on seed nuclei such as nickel-56, probably in neutron star mergers or in collapsing supernovae.The research paper is published in the journal Nature.

New type of kill switch to prevent genetically modified microbes from wreaking

first_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Science Fiction writers dreamed up the idea of mad scientists creating microorganisms that somehow get out into the world and kill everyone long before modern scientists had the skill to actually do it—but now that technology does exist and along with it fear that in trying to do something good, such as creating a cure for a bacterial disease, researchers could create a monster virus that not only harms patients, but jumps to others and causes serious harm or death. That fear is not ungrounded, as most biological researchers will attest, and that is why some of them are working on making genetically modified organisms safe. The idea is to modify genes to cause the organism to note when some chemical is present, and if so, to self-destruct—a modified virus or bacteria, for example, would die if exposed to a chemical present in the atmosphere. While such an approach is deemed practical by many, others would like to have access to a means for using the same technique on different organisms—those who hold patents on GMOs, for example, would like to be able to kill off their product if it gets into the hands of another entity. To meet that need, the researchers with this new effort came up with two new types of kill switches, which they have named ‘Deadman’ and ‘Passcode.’The Deadman solution is a new take on the kill switch idea from old time trains, a certain chemical must always be present or the modified microbe will die. Passcode, on the other hand is more complex, it combines the idea of a needed chemical and the absence of another. Microbes could be modified to be able to live only in the presence of two different molecules, for example, and the absence of another, or the reverse could be true. The designer could choose whichever “passcode” they desire.The main hurdle facing these new ideas and any others that may come along, of course, is in being able to prove that the microbes they modify will not evolve in ways that overcome the kill switches, either alone or by interacting with native microbes, making such efforts moot and possibly putting everyone at risk.

DOI: 10.1038/nchembio.1979AbstractBiocontainment systems that couple environmental sensing with circuit-based control of cell viability could be used to prevent escape of genetically modified microbes into the environment. Here we present two engineered safeguard systems known as the ‘Deadman’ and ‘Passcode’ kill switches. The Deadman kill switch uses unbalanced reciprocal transcriptional repression to couple a specific input signal with cell survival. The Passcode kill switch uses a similar two-layered transcription design and incorporates hybrid LacI-GalR family transcription factors to provide diverse and complex environmental inputs to control circuit function. These synthetic gene circuits efficiently kill Escherichia coli and can be readily reprogrammed to change their environmental inputs, regulatory architecture and killing mechanism. Researchers use CRISPR to create ‘kill switch’ for GMOs Journal information: Nature Chemical Biology Explore further (Phys.org)—A combined team of researchers from MIT and Harvard has come up with two new ways to hardwire a kill switch into a genetically modified microorganism to prevent it from going rogue. In their paper published in the journal Nature Chemical Biology, the team describes their technique, why they think it is better than other approaches and the ways it could be used. © 2015 Phys.orglast_img read more

Flavours of punjab

first_imgTraditional wares from Punjab such as phulkari embroidery work, the Punjabi jutti, nate-parande, bangles, wooden furniture and inlay items are being sold here in various exhibitions held to mark the upcoming harvest festival of Baisakhi.At the Indira Gandhi National Centre for Arts whose lawns have been temporarily transformed into a mini Punjabi village for a Baisakhi Mela. Among the many stalls at the IGNCA lawns is one which features a hawker from Manipur which is stocked with items ranging from phulkari to khanda to funky t-shirts with Punjab style prints on it.

This is the Punjabi alphabet,” says Awon Marei with a smile. “We generally don’t keep phulkari work in our shops in Chandigarh and Janpath but we have especially got it from the villages in Punjab to sell here. The phulkari work key-ring we have is from Sangrur where a part of the proceeds goes for the education of children there,” says Marei. The shop girl who sports a Punjabi ‘kada’ in her hand says she knows a lot about the Punjabi culture since she has been working with the shop for eight years now.

So this event will help people know more about Punjab. We have traditional performances like giddha, bazi, gatka dhadi and bhangra here. Besides that we have called stars like Vatsala Mehra, Harshdeep Kaur, Hardy Sandhu and Ammy Virk,” says Dhawan. Food stall features cooks from Amritsar dishing out specialties like Amritsari kulche and Amritsari macchi fry. Another Baisakhi Mela is being organised by Delhi Tourism at the Garden of Five Senses which will include cultural performances by artists of Sahitya Kala Parishad and Punjabi Academy. Meanwhile, entertainment destination the Kingdom of Dreams has roped in a band of singers led by Bollywood singer Kanika Kapoor of Baby Doll fame for an evening of merriment and music.“I’ll sing my latest numbers as most of them are in Punjabi and if there is a dhol then we’ll try doing few songs with dhol as well. However, we haven’t still decided on the exact numbers and we prefer going with the flow,” Kapoor said. The ‘Punjab Pavilion’ in the Culture Gully of the Kingdom of Dreams is also hosting special offers.last_img read more
