Credit: Courtesy of OSUThe Ohio State women’s soccer team (13-6-3) is headed to the Sweet 16 after defeating the Virginia Tech Hokies (15-4-2) on Friday afternoon 1-0 in the second round of the NCAA tournament. Freshman midfielder Arden Holden netted her first career goal with 11 minutes remaining to keep the Buckeyes’ postseason run afloat. With the win, the Scarlet and Gray are headed to their third Sweet 16 in the past six seasons. The beginning of the game was slow, as the first 15 minutes did not present many opportunities to score for either side. In the 20th minute, OSU finally got to a solid opportunity in the final third when senior midfielder/forward Michela Paradiso tried to curl one in from 20 yards out on the left wing but it sailed over the crossbar. Two minutes later, the Buckeyes had another opportunity to score when junior forward Lindsay Agnew sent a strong ball to junior forward Nichelle Prince, but a Virginia Tech defender cleared it away. The Hokies, who entered the game as the 14th-overall seed, were able to generate a scoring opportunity in the 43rd minute when sophomore forward Alani Johnson sent one on the frame, but OSU redshirt junior goalkeeper Jillian McVicker made a lunging save to preserve the scoreless match. The teams headed into the locker rooms at halftime tied 0-0. The Hokies led the Buckeyes 6-1 in shots, 1-0 on goal. OSU came back in the second half with plenty of opportunities to score early on, but the Buckeyes simply could not find the back of the net. In the 79th minute, the Buckeyes put the one and only goal on the board. Prince split two Virginia Tech defenders before playing the ball out to Holden who finished off the keeper. Holden has appeared in 21 of the Buckeyes’ 22 games this season, but her game-winning goal marked the first time in her young career she has scored. The final 11 minutes of play contained some opportunities for the Hokies to level the match, including a solid look off a free kick in the 87th minute, but they could not get past McVicker, meaning OSU was able to hold on for the 1-0 win. For the game, Virginia Tech held a sizable lead in shots, 20-5, including 4-2 on goal. McVicker made four saves to earn her second clean sheet of the season for OSU. The Buckeyes are set to play conference foe Penn State in the Sweet 16 after the Nittany Lions dominated Boston University in the second round, winning 6-0. In the lone meeting between the two teams during the regular season, Penn State topped OSU 2-1 on Oct. 24. With an opportunity to advance to the quarterfinals on the line, the rematch is set to take place on Sunday in State College, Pennsylvania. Kickoff is penciled in for 1 p.m.
Xabi Alonso is adamant that there are no teams in the World Cup that are better than Spain right now and sees no reason why they cannot be considered among the favourites to claim glory in RussiaLa Roja topped their World Cup qualifying group without losing a single game and in 10 games they won nine and drew just one, as well as scoring 36 goals and conceding just three.Among the likes of Germany and Brazil, the 2010 World Cup winners are expected to be one of the prime challengers at Russia.“I’m not just saying it, but I would put them among the favourites because I don’t see any side that’s better than Spain right now. I don’t know what’s going to happen in the games though,” Alonso told FIFA.comQuiz: How much do you know about David Villa? Boro Tanchev – September 14, 2019 Time to test your knowledge about Spanish legendary forward David Villa.“Germany are another of the big favourites. They’re a very strong side and they’re always there or thereabouts. The way they’ve been playing, it would be a massive surprise if they don’t make the semis, because they’re the champions and because of the new generation who’ve come into the team.“Brazil are also right in there. I think those three are above the rest.”He added: Then there’s Argentina, France and maybe a surprise or two.”Spain will begin with their World Cup campaign against Portugal on June 15.
Liverpool midfielder James Milner believes they should be relishing being on top of the Premier League rather than dwelling on the threat from their rivals.Jurgen Klopp’s side have somewhat dropped off in form since the start of the new year with just two wins in five league outings.1-1 draws against both Leicester City and West Ham United have left Liverpool particularly vulnerable now with Manchester City just three points away from snatching top spot.The Citizens will have the opportunity to do that in tonight’s trip to Goodison Park to take on Liverpool’s Merseyside rivals Everton.But Milner believes Liverpool shouldn’t be worried over the pressure of being the league leaders at this stage of the campaign.“Concerned about being top of the league in February? No, I’m happy!” Milner told Liverpool Echo.“We’re clear at the top of the league in February. There is a long way to go, a lot of games, tough games. We have just got to keep going.“If someone said we’d be three points clear at this stage of the season you’d have taken it.“There were people saying at the start of the season that Man City are the best team the Premier League has ever seen and stuff like that, so just to be close to them is good for us.“Playing for relegation and livelihoods and people’s jobs, that’s pressure. Being at the top of the table, we should be enjoying it.”The former England international, who has won the Premier League twice at City, accepts that changes at the top of the table are likely.Liverpool 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.Therefore, Milner believes Liverpool should just try to enjoy their lead and remain focused on themselves rather than on their rivals.“We’ve got to keep going and try and enjoy it,” he added. “There’s nearly a third of the season to go, such a long way.“I’ve been fortunate enough to win titles, I’ve been unfortunate enough to get relegated as well. I’ve experienced it, and these are the times you should be enjoying.“It wouldn’t surprise me if the league lead changes hands a couple of times before the end of the season.“We’ve just got to take care of our business. The last couple of games, we haven’t played well but we’re still picking up points.“That’s the positive side, we’re not losing games. There’s plenty we can improve on which is nice to know.”The Reds will be back in action on Saturday at home to Bournemouth in the Premier League.A point gained.

ALERT # 2 ON POTENTIAL TROPICAL CYCLONE NINE ISSUED BY THE BAHAMAS DEPARTMENT OF METEOROLOGY THURSDAY 12TH SEPTEMBER, 2019 AT 9 PM EDT Related Items:#magneticmedianews Facebook Twitter Google+LinkedInPinterestWhatsAppProvidenciales, TCI, February 22, 2017 – Residents tired of the crime are increasingly taking matters into their own hands; the latest report of an arrest of a known robber came last night and it was caught on camera.A Popular lounge owner was robbed, had video surveillance which clearly showed the face of that culprit as he unwittingly looked directly into the camera and revealed to the owner a face, he recognized. After calling the police, according to the cell phone video, and waiting an hour, he says, that businessman decided to go and get the man on the video himself.Colin Williams, better known as Jimbalaya is seen manhandling the alleged suspect, trying to tie him to a steel bar door and eventually turning the man over to two police officers. Photos of what his security cameras caught are in circulation; and it does appear to be the exact same man from the security footage in that cell phone video in the citizens’ arrest. It was a relatively smooth arrest by Jimbalaya at his Kew Town bar; Police took over and led the man away in handcuffs.Residents are hoping that charges can stick and this suspect, once found guilty can be locked away and off the streets. Reports are that crime has decreased in the TCI, but brazen home invasions and armed attacks appear to be more frequent and certainly are more violent.Police confirmed late today that they still have that man caught by Jimbalaya in custody.#MagneticMediaNews Recommended for you Electricity Cost of Service Study among the big agenda items at September 11 Cabinet meeting Facebook Twitter Google+LinkedInPinterestWhatsApp The Luxury of Grace Bay in Down Town Provo

David Jaffe, with the Broad Institute reported to an audience at the Advances in Genome Biology and Technology meeting in Florida last week that he has been asked by Oxford Nanopore to try out the new the device, called the MinION, and has found it to be promising. Explore further Oxford Nanopore Technologies created a stir in the biological sciences world in 2012 when representatives for the company announced that its research team had successfully created a sequencing device based on nanopore technology and that an inexpensive prototype would be delivered to researchers outside the company soon thereafter. The company apparently ran into difficulty ramping up its pore technology and had to find some alternative materials—thus the two year delay.Nanopore sequencing is where single strands of DNA are pulled through a pore—as each base pair passes through the pore its conductivity is measured—information that can be used for identification by a computer. The advantage of this approach is that at least in principle, any strand length can be sequenced.The MinION isn’t for sale yet—at this time the company is making prototypes available to a select few notables in the genome sequencing field—each will have to pony up $1000 as a down-payment for the honor. The device plugs into a port on a computer, which does the processing. Along with the device, which has been compared to the size of a pack of gum, Oxford Nanopore Technologies will send along DNA samples that researchers can use to learn how to use the new device—after that, they can sequence anything they want. In testing strands of two types of bacterial DNA sent to him, Jaffe reports having mixed results —long stretches of data were obtained correctly in some cases, but in others there were some errors. In order to assemble the entire genome of a type of bacteria, for example, he had to also use a sequencing device made by another company. He noted that he is optimistic about the device, however, as reps from Oxford Nanopore have assured him that error rates can be reduced using certain techniques even as improvements to the device are being worked out back at the lab.If the error rates using the MinION can be reduced to a practical level, the device could mark a turning point in gemone sequencing as it would be a device that could be carried and used for fieldwork. And though the cost of such a device has not been announced, Oxford Nanopore has repeatedly used terms such as inexpensive and affordable to describe it, indicating it will cost much less than other sequencing devices currently on the marker, once it’s ready for sale.

They found that the NHC bound to gold forms an adatom that then traverses the gold surface in a ballbot-type motion. Their report appeared in a recent issue of Nature Chemistry.NHCs form a particularly strong bond with gold because of the sp2 hybridized lone pair of electrons on the carbon atom (See figure of NHCs above). Studies have shown that NHCs can be used to form particularly stable self-assembled monolayers (SAMs) on gold surfaces and can even be modified after formation of the monolayer, but these studies are difficult to compare with each other because they do not have similar R groups.The nitrogen-substituted R groups play a significant role in the behavior of the NHCs. Bulky R groups prohibit dimerization but may affect the stability of monolayer formation. Also because the nitrogen atoms are part of an aromatic ring, they serve as electron donors to the substituents. The type of substituent affects the electronics of the molecule.In this study, Wang et al. used three different NHCs that were synthesized in the Glorius group, each of which had R groups that had previously been studied and represented a range of steric and electronic properties. These groups include IMes which has 2,4,6 trimethyl phenyl rings as the N-substituents; IPr which has 2,6-diisopropylphenyl substituents; and IMe which just has methyl groups as the N-substituents. Play Credit: (c) Nature Chemistry (2016) doi:10.1038/nchem.2622 Beginning with carboxylate versions of IMes, IPr, and IMe, they deposited the NHCs onto the gold surfaces via ultrahigh vacuum vapor deposition. XPS confirmed that the NHC, not the carboxylate version, was bound to the gold surface. Scanning tunneling microscopy (STM) showed that IPr and IMe made neat, controlled surfaces, while IMes molecules were less ordered. Citation: Self-assembled monolayers of NHCs on gold have ballbot-type motion (2016, October 20) retrieved 18 August 2019 from https://phys.org/news/2016-10-self-assembled-monolayers-nhcs-gold-ballbot-type.html Journal information: Nature (Phys.org)—Self-assembled monolayers are molecules anchored to a surface. These molecules have been used to advance the fields of molecular sensors and electronics. Monolayers on gold surfaces are typically anchored by a thiol. One alternative to thiols are N-heterocyclic carbenes (NHCs). First isolated in 1991, NHCs have proved an important molecule for practical uses because it can serve as a ligand for transition metals as well as some main group elements. NHCs have also been used for organocatalysis, cross-coupling reactions, and pharmaceuticals. This document is subject to copyright.

Credit: (c) Nature Chemistry (2016) doi:10.1038/nchem.2622 At various surface coverage densities, the IPr surface would form islands that broke apart and recombined. This indicated that the surface was mobile, but there was no change to morphology of the gold surface. Despite this mobility, the bond between the NHC and the gold surface proved to be highly stable at high temperatures.This behavior may be explained by the formation of adatoms, or the interaction of one NHC molecule with one gold atom. This adatom then moves around the surface as one entity, which the authors liken to ballbot movement. They confirmed this structure by looking at the height of the IPr monolayers.DFT calculations helped to explain how exactly these adatoms formed and moved. IPr and IMe likely bound to a gold atom that was pulled from the surface. Simultaneously, a gold atom from the second layer moves into the vacant hole. The gold atom that was pulled from the surface was bound irreversibly to the NHC to form an adatom that then readily moved across the surface. Additional free energy calculations looked at the effects of bulky R groups, specifically comparing IPr with IMes. Wang et al. found that the pi interactions between the phenyl rings and the surface play a role in adatom formation and mobility. They reasoned that there is a balance between steric hindrance, as with IPr, and pi interactions, as displayed with IMes. And, indeed, the non-bulky IMe compound, which was more mobile than IPr and IMes, was able to form dimeric and trimeric complexes with one gold atom.This study provides important insights into how NHC-Au monolayers form and behave. They seem to form a stronger bond than thiols with gold, but they also display mobility that is influence by the identity of the nitrogen substituents. The NHCs that tend to have weaker pi interacts with the gold surface readily forming adatoms that then move across the surface like a ballbot. More information: Gaoqiang Wang et al, Ballbot-type motion of N-heterocyclic carbenes on gold surfaces, Nature Chemistry (2016). DOI: 10.1038/NCHEM.2622AbstractRecently, N-heterocyclic carbenes (NHCs) were introduced as alternative anchors for surface modifications and so offered many attractive features, which might render them superior to thiol-based systems. However, little effort has been made to investigate the self-organization process of NHCs on surfaces, an important aspect for the formation of self-assembled monolayers (SAMs), which requires molecular mobility. Based on investigations with scanning tunnelling microscopy and first-principles calculations, we provide an understanding of the microscopic mechanism behind the high mobility observed for NHCs. These NHCs extract a gold atom from the surface, which leads to the formation of an NHC–gold adatom complex that displays a high surface mobility by a ballbot-type motion. Together with their high desorption barrier this enables the formation of ordered and strongly bound SAMs. In addition, this mechanism allows a complementary surface-assisted synthesis of dimeric and hitherto unknown trimeric NHC gold complexes on the surface.
Kolkata: When France walk out of the tunnel one last time this FIFA World Cup to take on Croatia in Sundays final, pockets of the football crazy city of Kolkata will share the common prayer with the French footballers in Moscow vying to lift the coveted trophy for the second time.At Alliance française du Bengale, affiliated to the international network of the Alliances françaises in the world, around 50 expatriates and students will come together in front of a giant screen at 8.30 pm local time to cheer for their team. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killed”For the final, we will screen the match at Alliance française du Bengale but only for our students, members and expats. There will also be some of the expats of other countries involved in the World Cup,” Fabrice Plançon, director of Alliance française du Bengale said.France played like a team possessed against star-studded Belgium in the semi-final on Tuesday, with centre back Samuel Umtiti netting a second-half winner.The Les Blues take on Croatia in the summit clash. The Croats came back a goal down to put it across England 2-1 in the second semi-final on Wednesday. Also Read – Naihati: 10 councillors return to TMC from BJPAround 25-30 expats and French supporters in the city gathered at a plush city pub, ‘Someplace Else’ in south Kolkata to watch Tuesday’s riveting game. “We were in the pub with French expats from the Consulate, some French volunteers and some Indian French fans here,” Plançon said.”Thanks to our goalkeeper, Hugo Lloris, we won the game I think. It was some kind of magic actions from him. After the game since it was late and we all had work the next day, we went home happy.” A day before the final comes the French national day. Plançon said it will be more special because of the football team playing in the title round. “On the French national day, an annual reception will be given by the Consulate at Novotel. We will celebrate the national day on the eve of the final, so it will be very exciting this year. The next day, let’s see what will happen,” he said.Meanwhile in Chandannagar, located 35 kilometres north of Kolkata, which was once a French colony then known as Chandernagore, the civic body has decided to beam the live telecast of the final on a giant screen on the bank of the Hooghly river. “We have planned it near Rabindra Bhavan on The Strand,” an official of Chandannagar Municipal Corporation said.Some programmes will also be organised to highlight a slice of France in the city.”The city is historically so close to France. I feel everybody should get behind the French on Sunday,” quipped Plançon. An hour’s drive from Kolkata, Chandannagar in Hooghly district was one of the first outposts of India’s colonial past, a French colony rather like Puducherry.It remained an overseas territory of France in India for different time periods stretching over 250 years since 1673. It finally became a part of the Indian union in 1952, five years after the country won independence from British rule.The town of Chandannagar still has strong French cultural links, which draw tourists from the European nation. The Chandannagar Museum and Institute (Institut de Chandernagore) possesses a rich collection of French antiques, while the Chandannagar gate constructed in 1937 on the anniversary of the Fall of Bastille, has etched on it the slogan of the French Revolution “Liberté, égalité, fraternité (Liberty, equality and fraternity)”.A French cemetery stands opposite a large lake. Another major attraction is the Sacred Heart Church that was designed by French Architect Jacques Duchatz, and inaugurated in 1884. On the day of the semi-final, the excitement of France’s qualification was palpable across Chandannagar —from Taldanga to Urdu Bazar, from The Strand to the Hospital More.”Like it is for maybe a Messi or Neymar across Kolkata, here our heroes are (Antoine) Griezmann, Kylian (Mbappe). I remember I was young in 1998 and we did not sleep the entire night,” a Chandannagar resident said.France lifted the World Cup for the first time in 1998, blanking Brazil 3-0. In 2006, they reached the final only to be beaten by Italy on penalties.
