Costacurta hails Balotelli return, Mancini vows Italy ‘rebirth’

first_img0Shares0000Mario Balotelli has not played for Italy since the 2014 World Cup but has been playing well for Nice © AFP/File / VALERY HACHEMILAN, Italy, May 20 – Top Italian FA official Alessandro Costacurta on Sunday welcomed Roberto Mancini’s decision to recall Nice striker Mario Balotelli as the new Italy coach promised a “rebirth” of the national side.Balotelli, who has not played since Italy’s humiliating group-stage exit from the 2014 World Cup, has been recalled by Mancini for three upcoming friendlies. And Costacurta said Balotelli’s form at Nice had warranted him being given another a chance.“Becoming a parent does change you and nobody can attest that more than Mancini,” said the former AC Milan defender and current federation deputy commissioner.“I think Balotelli’s performances on the field were worthy of a call-up.”Balotelli — who Mancini coached at both Inter Milan and Manchester City — has scored 13 goals in 33 appearances for the Azzurri but had been overlooked due to behavioural issues.Mancini took over last Monday, six months after Gian Piero Ventura was sacked following Italy’s failure to qualify for the World Cup in Russia, and takes charge of his first game against Saudi Arabia in St Gallen, Switzerland on May 28.“Usually big disappointments can lead to great triumphs,” said Mancini.“In difficult moments that is when Italy found their pride and these players must take us back to the top of the world, where we deserve to be.“I want this to be the Italy of rebirth.”Mancini and Costacurta were speaking on the sidelines of the Kick-Off 2018 event organised by the Italian FA at Coverciano, near Florence.“I think Italy are still a football superpower, as we have 50 million coaches,” joked Mancini about Italy’s passionate fans.“I’m always very positive in general, even if people say Italy no longer has as much talent.“We had perhaps too much talent all together when we won the World Cup, but now we just need to give them time to grow and develop, keep the faith towards a good future.“Our football philosophy helped us win four World Cups and lose three finals.“Perhaps we’ve done better than Brazil all things considered, as we played more finals, even if we could never play as well as them, or like Spain in recent years.”Meanwhile, Costacurta said he hoped goalkeeping great Gianluigi Buffon — the holder of a record 176 caps — would have a change of heart and play one final friendly.“I’m sorry that Buffon does not want to do a goodbye with the national team like he did with Juventus, it would have been nice if all of Italy could have thanked him for what he has done over the years.“At this stage, I don’t think he’s going to change his mind, even though it doesn’t hurt to make a call or a text.”The Italians will play further friendlies against France in Nice on June 1 and the Netherlands, who also failed to reach the World Cup, three days later in Turin.0Shares0000(Visited 2 times, 1 visits today)last_img read more

Chameleons ballistic tongue inspires robotic manipulators

More information: Alexis Debray. “Manipulators inspired by the tongue of the chameleon.” Bioinsp. Biomim. 6 (2011) 026002 (15pp). DOI:10.1088/1748-3182/6/2/026002 With the aim to mimic the mechanisms and performance of the chameleon’s tongue, researcher Alexis Debray of Canon, Inc., in Tokyo, Japan, has developed four ballistic robotic manipulators. Each of the four manipulators excels at copying a certain part of the chameleon’s tongue, and insights from each design could eventually be combined to create a more advanced chameleon tongue that could have manufacturing applications. Debray’s study is published in a recent issue of Bioinspiration & Biomimetics.“As far as I know, this is the first published demonstration of manipulators based on the chameleon tongue,” Debray told PhysOrg.com. “The particular mechanism of the tongue of the chameleon allows for fast accelerations and velocities and also applies no force during most of the motion.”As Debray explains, what we normally think of as the tongue of the chameleon is actually a larger system called the hyolingual apparatus. The tongue is just a small component on the front tip of the hyolingual apparatus. The majority of the hyolingual apparatus consists of the long, thin hyoglossus complex, which is the part that folds up like an accordion inside the chameleon’s mouth. The rapid movement of the chameleon’s hyolingual apparatus involves three phases: projection, catching, and retraction. Each of these three phases is controlled by a different system. The tongue (tip of the hyolingual apparatus) contains the accelerator muscle and collagens that control the projection. When the chameleon is ready to project, it slowly protrudes its tongue out of its mouth. Then, the tongue’s accelerator muscle projects the tongue off a bone inside the chameleon’s mouth. No applied force is needed to keep the tongue – and the rest of the hyolingual apparatus – moving forward. When the tongue reaches its prey, a tongue pad containing a small suction on the tip of the tongue can stick to the prey. Finally, the hyoglossus muscle in the accordion-like hyoglossus complex retracts the tongue at a constant velocity. Although the three phases are controlled by different systems, they occur in a single smooth, continuous motion.center_img This document is subject to copyright.

Like the chameleon tongue, Debray’s robotic manipulators use different specialized systems for projection, catching, and retraction. To project, all four manipulators use a coilgun in place of the chameleon tongue’s accelerator muscle. Elastomers and/or cotton string is used in place of the chameleon’s hyolingual apparatus. Instead of folding up like an accordion, the elastomers and string are wound around a reel. As for catching, the robotic manipulators use magnets on the tip of the elastomers, which attract magnetic “prey.” For retraction, the manipulators use either an elastomer, a DC motor connected to a reel and string, or a combination of both. One of the manipulators also had wings on the mobile part, which could allow researchers to take advantage of aerodynamic effects.“In the future, movable wings will allow controlling the trajectory after the ejection of the tongue, which is not possible now,” Debray said. “In our experiments, the wings are not movable. However, their aerodynamic effect on the trajectory of the tongue has been demonstrated experimentally. So far, aerodynamic effects have been poorly studied in the field of manipulators.”Using a high-speed camera, Debray could track the manipulators in motion. The results showed that the robotic manipulators could reach a projection velocity of 3.8 meters/second without the need for a continuously applied force, which is similar to the velocity of the chameleon tongue. In addition, the robotic manipulators could reach an acceleration of 919 meters/second2, which exceeds that of the chameleon (374 meters/second2). The manipulators that used a DC motor and string for retraction had the same extension ability as the chameleon tongue, and could also adapt to variations in the targets’ distances, as chameleons can. By incorporating various end effectors onto the robotic manipulators, the devices could have a variety of applications, especially for products passing on a factory line. For example, manipulators with sensors could be used to sense data on products. Stamps and catching devices could be used to deposit patterns and manipulate objects, respectively. Using a mechanism based on the chameleon’s ballistic tongue could provide certain advantages compared with other manipulators due to the small size and flexibility. Further, because ballistic manipulators do not apply a continuous force during their forward motion, an accidental collision would be less severe and likely cause less damage compared to a device being pushed forward. As Debray explained, the current manipulators lack reliability, and so they cannot yet be put to practical use.“The work presented in the paper is a first step towards manipulators inspired by the chameleon tongue,” Debray said. “Further development is needed in order to use them in factory lines. However, the ultimate goal of this work is the manufacture of Canon products such as cameras and printers, among others.” (PhysOrg.com) — Although the lungless salamander and some frog species have developed ballistic tongues, the chameleon’s ballistic tongue is the fastest, the longest, and the one that can catch the heaviest prey. A chameleon’s tongue can elongate more than six times its rest length, zipping forward at speeds of 3.5-10.5 meters/second – faster than a human eye can follow. The tongue is called ballistic because, like all ballistic objects, it moves freely without any applied force during its forward motion. Once the chameleon’s accordion-like tongue is ejected, it continues moving forward under its own inertia.

CPM BJP Congress hold rally together in Nadia

first_imgKolkata: The allegations made by Trinamool Congress supremo Mamata Banerjee that Congress, CPI-M and BJP are fighting the three tier Panchayat election holding each other’s hands when a rally comprising the members of these parties was taken out in Nadia on Saturday.The rally which was taken out at Gangnapur gram panchayat area in Nadia was led by Rama Biswas, CPI-M MLA and state committee member of the party. She was the former Sabhadhipati of Nadia district. The candidates of all the three parties took part in the rally and urged people to vote for them. It may be mentioned that Mamata Banerjee have made this allegation over and again and criticised CPI-M for failing to stop the flight of its cadres of BJP. Sixty thousand cadres in Bengal have not renewed their membership and a significant number of these floating party workers have joined BJP. Also Read – Heavy rain hits traffic, flightsThe Panchayat election has witnessed an unprecedented number of Independent candidates. A total of 16,880 candidates are contesting in the Panchayat election. This is more than the number of candidates filed by Congress. Party of Democratic Socialism (PDS), CPI-ML (Liberation) and SUCI have filed their nominees as Independent candidates. Their collective strength will be around 880. The remaining 16,000 candidates are all members of various political parties. They are contesting the election without a party symbol. Political analysts said in many areas BJP is not contesting in its official symbol and has nominated an Independent candidate. CPI-M and Congress have towed this line. In Gram Panchayat, where the number of voters is less and every vote matters, fielding an independent candidate will put pressure on the ruling party.last_img read more

Presidency varsity fails to meet handover deadline

first_imgKolkata: Presidency University (PU) has failed to meet the November 15 deadline given by the state Higher Education department with regard to the handover of Hindu Hostel. PU Vice-Chancellor Anuradha Lohia has sought another 15 days’ time for completing some work pertaining to the habitationof the students. State Education minister Partha Chatterjee has summoned the university authorities on Monday and asked for an explanation behind the delay. On being questioned about the inability to meet the deadline over the handover, PU V-C Anuradha Lohia said: “We had not set any deadline. The government had given a deadline. I had said mentioned that the entire work will be finished off by January. We tried our best to stick to it and everybody involved in the construction worked hard even during Durga Puja and Diwali but could not complete the work. We hope to complete the entire work by November 30.” According to the V-C, the state Public Works Department (PWD) that is in-charge of the renovation of the hostel has submitted a report stating that a little bit of work is still pending when it comes to the safety and security of the boarders. “We are also awaiting the certificates of safety from the state Fire and PWD departments,” Lohia added. A senior official of PU pointed out some areas where work is still pending. The dining room and the kitchen need some more work. Some broken glasses are scattered here and there which need to be removed. “We will put LPG gas to use for cooking and do away with diesel that was earlier used for the purpose. We are creating a gas bank for this,” the official said. It may be mentioned that the Hindi Hostel was closed for renovation in July 2015 and the boarders were provided with lodging facilities at Tarulia in New Town. The university has failed to meet deadlines on more than one occasion in case of Hindu Hostel handover. The students had resorted to agitation for a long period demanding the same.last_img read more
