first_img1 Northern Ireland captain Steven Davis has been forced to withdraw from Friday’s Euro 2016 qualifier in Romania.The Southampton midfielder has been battling to prove his fitness since a hamstring injury forced him off in the first half of the Saints’ Premier League win over Leicester last weekend, but has finally admitted defeat.The team will now travel to Bucharest on Wednesday evening without their inspirational skipper, who has played every game since inheriting the armband almost three years ago.Davis’ absence represents a huge blow for Michael O’Neill’s side, who are the surprise leaders of Group F after kicking off their campaign with three successive wins.A point in Romania would see them remain at the summit until at least the next round of fixtures in March.In light of the injury, winger Niall McGinn said: “No-one does more than Davo. He’s our captain, he’s definitely our leader on the pitch and he’s done so well for us for a number of years.“He came in to the team hotel on Tuesday because he’s been with his club having scans, he was just chilling and taking it easy but there’s no doubt he’ll be hugely disappointed not to have made it.“It’s a massive miss for us but there are other players who come in and do a good job.“It will show the strength in depth we have if we can cover for him.“He brings so much with his performances alone and he helps bring up everyone else around him to those standards.”Goalkeeper Roy Carroll added: “Steven has been fantastic since I came back into the set-up. He’s never missed a game.“But you can’t take a chance on a player of his quality. We don’t want to make the injury worse if he isn’t 100 per cent and we have other players who can come in and give 100 per cent.”O’Neill, who had already lost forward Jamie Ward and full-back Ryan McLaughlin to injury, must now replace Davis as captain and in the centre of the park.Brighton defender Aaron Hughes led the side for a decade before Davis and would be an obvious candidate to step in, but he has also got question marks over his match fitness after suffering an ankle problem.Gareth McAuley is another option, though turned down the chance to lead the team out in Greece last month on the occasion of his 50th cap in deference to Davis.In midfield, O’Neill can choose from the likes of Sammy Clingan, Paul Paton and Corry Evans, as well as uncapped Rochdale man Matthew Lund who was called up as squad cover on Tuesday.

Lilian’s son who is top of the Bundesliga with Borussia Monchengladbach Brazil, beware! Messi and Argentina out for revenge after Copa controversy Best player in MLS? Zlatan wasn’t even the best player in LA! The Belgium coach has been linked with taking over at Monaco but Deschamps referenced Henry previously being lined up for the Bordeaux job earlier in the year, only for the deal to fall apart.”I don’t know if you always have the right information but so far nothing is official yet,” Deschamps told reporters. “It was the same case in Bordeaux at the beginning of the season. But I wish him [Henry] all the best.”’Titi’ has taken some time to make his choice, he is doing well with Belgium. If he gets this opportunity, which is not confirmed yet, he should jump in the deep end at some point.”So let’s wait and see. Maybe tomorrow you’ll tell me that he is not going to Monaco eventually.”And there is still a coach. Leonardo Jardim is the coach, even if I like Thierry Henry I don’t want to anticipate things as I respect Jardim. I’m not sure it would happen as everyone is announcing.”Henry quit his role as a television pundit this year to concentrate on his coaching career.last_img read more

first_img Jamaica is set to benefit from an initial US$7.52 million in grant funding under the ninth cycle of the Caribbean Development Bank’s (CDB) Basic Needs Trust Fund (BNTF 9).The money will go towards the areas of education, transportation, enterprise development, and water and sanitation, through projects implemented by the Jamaica Social Investment Fund (JSIF).The allocation is part of a provision of US$40.8 million being made available to nine Caribbean borrowing member countries of the CDB, under the BNTF.The BNTF is the flagship poverty-reduction programme of the CDB, aimed at contributing to improvement in the living conditions of poor and vulnerable communities in participating countries.Speaking at the official launch of the project today (October 17) at the Courtyard Marriott hotel in New Kingston, Minister of Finance and the Public Service, Hon. Audley Shaw, said the initiative will assist in empowering the lives of beneficiaries.“We are quick to get these funds in the hands of the JSIF, because we know that when it comes to the JSIF, we get every bang for the buck; we get good performance. They have projects done on time (and) within budget, and we are really proud of the JSIF as one of the outstanding public-sector agencies in Jamaica,” he said.The Minister lauded the CDB for implementing the programme, adding that poverty reduction is a crucial component for economic growth and development.He said the BNTF will assist in improving the lives of the country’s most vulnerable, particularly in the areas of education and human development.Meanwhile, Director, Projects Department, CDB, Daniel Best, informed that Jamaica is also eligible to benefit from an unallocated incentive amount of US$5.2 million, to be distributed at midterm based on project performance.“These funds are to be carefully targeted through an evidence-based country policy framework or action plan, which responds to poverty, particularly in rural areas,” he said.Mr. Best noted that through the BNTF, the CDB supports governments in their poverty-reduction efforts by promoting socio-economic activities, environmental protection and sustainable development.“Over the years, BNTF has formed specific partnerships, mainly with public works, water sector, and national training institutions. Under BNTF 9, however, we are committed to leveraging additional resources beyond our traditional funding sources to accelerate progress on poverty reduction,” he said.Managing Director, JSIF, Omar Sweeney, said BNTF 9 will continue to build on programmes that support education, transportation, road access, drainage and water supply.“We will also introduce a component for enterprise development, and that will focus on agriculture and tourism, and developing new technology for persons in the rural areas to really have a sustainable livelihood,” he said.The ninth cycle of the BNTF will continue to finance sub-project interventions in core priority sectors of water and sanitation, basic community access and drainage, and education and human resource development, including livelihoods.Encouraging greater private-sector partnership has been built into the programme design to leverage additional resources for reducing poverty.The core purpose of the project will be to facilitate the development of rural communities through increased access to basic services, thereby advancing Jamaica’s thrust towards full rural development. The project is to be completed by December 31, 2020.The BNTF is one of the longest-running regional poverty-reduction programmes in the Caribbean, and stands out in the global development arena for its community-driven approach tailored for the Caribbean context.

first_img Physicists add amplifier to quantum communication toolbox Practically speaking, single photon detection has not been something pursued very heavily at the wavelengths used for telecommunication signals. Part of the problem is that performance of single photon detectors are rather constrained at such long wavelengths. But, says Robert Thew, a scientist at the University of Geneva, the time is coming when single photon detectors may be needed in telecommunications. Citation: Single photon detectors for telecommunications wavelengths (2008, August 29) retrieved 18 August 2019 from https://phys.org/news/2008-08-photon-detectors-telecommunications-wavelengths.html Explore furthercenter_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. “Up until now,” Thew tells PhysOrg.com, “classical communication has not done too badly with the detectors available now. But now they are getting pushed to the limit as optical communications explodes. Single photon detectors are becoming more important.”In order to improve the ability of a single photon detector to work with signals with telecommunications wavelengths (about 1550 nanometers), Thew and his colleagues at the University of Geneva, Zbinden and Gisin, suggest a scheme that involves upconverting these signals using a tunable pump source to a silicon detector. Their work is published in Applied Physics Letters: “Tunable upconversion photon detector.”“Photon detection in general is a key enabling field of research,” Thew explains. “And it is improving all the time. Photon detection is used for quantum cryptography and computing as well as for metrology and telecommunications. Our experiment is one that shows how telecom wavelength photons can be converted into the regime of silicon detectors.”These Silicon detectors, Thew explains, are useful because they offer a high temporal resolution. While experiments have been done showing upconversion of silicon detectors, this Geneva group has added another element: tunability.Usually, upconversion experiments do not feature a simple and practical method of controlling wavelengths. “These systems are dedicated at well-defined wavelengths,” Thew says. “This works well for some things, but sometimes you want to be able to change the wavelength. That is what we are working on.” Of those that do seek for tunability, they can rely on temperature control to change the wavelength or use the nonlinear phase matching scheme with different poling periods. Thew and his peers decided to make a tunable photon detector using laser tuning.“All upconversion schemes rely on mixing two lasers to generate a third with the desired wavelength by a nonlinear process,” Thew explains. “Our practicality comes from the choice of components. The precision comes from the choice of silicon detector. The tunability comes from being able to tune one of these lasers that are initially mixed.” Not only is this detector tunable, but it is also compact and more cost efficient than similar photon detectors. And, as telecommunications continues to advance, this could be a good way to continue the improvements seen in the last few years. “[F]aster communication systems necessarily have to work with lower intensities (fewer photons) and it is here that the single photon detection technologies will be needed,” Thew explains. “This offers practicality and low cost. The idea is that we keep simplicity, but gain the advantage of tuning wavelengths.”“Things are improving all the time in this area of study,” Thew continues. “Having tunable photon detectors would be helpful for many experiments and applications. We are taking advantage of being able to do this with a silicon detector. What we have done offers a huge advantage for this type of approach.”Copyright 2007 PhysOrg.com. All rights reserved.
