About the authorFreddie TaylorShare the loveHave your say Chelsea midfielder Mount feared long-term injuryby Freddie Taylora month agoSend to a friendShare the loveMason Mount has revealed he feared he had suffered a long-term injury against Valencia last week.The midfielder was substituted after 15 minutes during the 1-0 loss, but returned to start against Liverpool on Sunday.”As soon as I did it I thought it was going to be a long-term injury,” Mount said.”But then I iced it and it calmed down and I realised it was not as bad as I first thought. The next day I was jogging on it a little and from then I knew there was a chance of me being involved [against Liverpool yesterday].”There is still swelling there now but it is solid and I felt good and I trained the day before. I was pretty positive the day before the game that I would be involved.”He added: “You have to block the injury out of your mind and focus on the game.”When I had that chance which I felt I should have scored I rolled my ankle a little bit and it felt fine. It was fine throughout the whole game. It was solid.”Your Champions League debut, you don’t want it to end so soon, but that is football, it happened, and I try to stay positive. “I looked forward to the Liverpool game and set a goal that hopefully I could get ready for that. I feel like I am a quick recoverer and we worked on it hard and I was able to get back.”
OTTAWA – The OECD is raising its economic forecast for Canada amid a strengthening global economy, but also warns that tensions are appearing that could threaten global growth.The Paris-based economic think-tank says trade protectionism remains a key risk that would negatively affect confidence, investment and jobs.The OECD comment follows moves by the U.S. to impose tariffs on steel and aluminum imports from most countries in the world, with Canada and Mexico exempted.The OECD says it now expects the Canadian economy to grow 2.2 per cent this year, up from an earlier prediction of 2.1 per cent.It also raised its Canadian growth outlook for next year to 2.0 per cent compared with its forecast in November for 1.9 per cent.The OECD says the revised outlook compares with growth of 3.0 per cent last year in Canada.
New Delhi: Ahead of the Lok Sabha polls, the Election Commission (EC) has ordered 26 lakh indelible ink bottles worth Rs 33 crore. The seven-phase election will begin on April 11 and conclude on May 19. In the 2014 Lok Sabha elections, the poll panel had bought 21.5 lakh phials, 4.5 lakh less than this year.Mysore Paints and Varnish Ltd, a government of Karnataka undertaking, is the only authorised manufacturer of indelible ink for the Election Commission. Mysore Paints and Varnish Ltd Managing Director Chandrashekhar Doddamani said that the company has received an order for 26 lakh phials of 10cc each from the Election Commission. “The expected turnover is approximately Rs 33 crore,” he said. The order, Doddamani said, is higher than the last general elections by 4.5 lakh phials. In this election, nearly 90 crore people are eligible to case their votes for which the Election Commission will set up nearly 10 lakh polling stations across the country. In 1962, the Election Commission, in collaboration with the Law Ministry, National Physical Laboratory and National Research Development Corporation, had made an agreement with Mysore Paints and Varnish Ltd for supply of indelible ink for Lok Sabha and assembly elections. Since then, it has been supplying the ink for elections in India. A bottle of indelible ink contains 10 cubic centimetres (cc). As per modern measurement methods, one cubic centimetre is equivalent to one millilitre. Mysore Paints and Varnish Ltd exports indelible ink to more than 30 countries across the globe. Soon after the note ban, the company was asked to provide indelible ink to banks to mark customers exchanging defunct currency notes to check suspicious deposits. Grappling with unending queues and frayed tempers in banks and to check operation of syndicates after the note ban, the government had introduced the system of marking customers exchanging defunct currency notes with indelible ink.
Bengaluru: Former cricketer Rahul Dravid, who was part of the Election Commission’s campaign to boost voting, will miss out on voting in the current Lok Sabha polls as he did take steps to get his name included in the voters’ list after a change of residence here.Dravid and his family had moved from their ancestral house in Indiranagar to Ashwathnagar and subsequently names of him and his wife were removed from the Electral Rolls. This was based on Form 7 for deletions submitted by his brother, Karnataka Chief Electoral Officer Sanjiv Kumar said here Monday. “…but after shifting to new residence Rahul Dravid did not take steps to get his name included in the electoral roll although registration officials visited there several times,” Kumar said. The electoral authorities came to know about Dravid’s name not being in the list after finalisation of the electoral rolls.
Mumbai: 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.

Dear Editor,Our Country was founded by men of faith who believed in creating a foundation where liberty and justice would stand and not fall. A nation whose people were free from tyranny and government oppression. The U. S. Constitution is that very foundation. It is the “supreme law of the land”. Provided in the U.S. Constitution is the right to free speech. This right is not found in the eighth, ninth, or tenth amendment, but rather in the first amendment because of its enormous magnitude of importance.I believe the people of Wilmington, who have witnessed abuses of power in the position of Moderator, have to ask themselves this question: Will the denial of free speech continue to be tolerated or will my vote for a new Moderator say “TIME’S UP” for violating our civil rights? Let’s build on the foundation of freedom and let liberty, justice, and truth deliver the people of Wilmington out from the grip of government oppression. May the patriots of Wilmington make “Town Meeting”, which is the most important financial meeting of the year, be a meeting void of deceit, void of phony over budgeting, and void of actions that force good families out of their own community.As I go around town, I meet many elderly people that have retired and had to go back to work because they can’t afford their real estate taxes. I recently met a senior citizen that is 91 years old and still has to work. I also recognize that there are families with children. These children make friends in school, in their neighborhoods, in sports and in other activities. When a family is forced out of town this is a traumatic experience for a child. As I drive around town, I see many “for sale” signs on people’s houses who have been here for decades. This is a very sad truth. I believe the cause can be pointed directly at an irresponsible local government that has forgotten its mission statement and has gotten self-centered and out of control.The question of whether there is conflict of interest has to be introduced into the conversation for a solution. Can a moderator, who has a relationship to a family law firm that brings business before the town looking for special permits, variances, and other approvals, be trusted with allowing opposition and challenge against the very government that will grant an approval? Do you believe he has broken that trust? Can a solution to government financial oppression be attained if people are denied the right to question, expose, challenge, or oppose?Let the great “Patriots of Wilmington” come together and stand on the foundation of freedom and demand liberty, truth, and justice. Let your right to challenge crooked government no longer be violated. Let us stand and say that a violation of the “supreme law of the land” is reproachable no matter what. “REPROACHABLE” even if Town officials past and present don’t respect the law. “TIME’S UP” Vote April 28th or get an absentee ballot from Town Hall. Help by bringing other supporters.Thank you,Kevin MacDonald(Candidate for Moderator)Like Wilmington Apple on Facebook. Follow Wilmington Apple on Twitter. Follow Wilmington Apple on Instagram.

[Representational Image]twitterYou can call it coincidence, but for the past couple of months, many earthquake predictions made by self-proclaimed seismic researcher Frank Hoogerbeets have turned true, and his recent forecast on upcoming quakes is capable of sending chills in your spine. In a recent post on his website ‘Ditrianum’, Hoogerbeets has claimed that a powerful earthquake which may measure 7 in the Richter scale could hit the earth either today or tomorrow.”Critical planetary and lunar geometry in the last two days is likely going to trigger large seismic activity from the 10th to the 12th, possibly over 7 magnitudes,” wrote Hoogerbeets on his website.Interestingly, the predictions of Hoogerbeets come at a time when a preliminary magnitude-4.0 earthquake was reported on May 11, in Cleveland. Even though no noted destruction happened in the affected area, the USGS is apparently collecting responses from people who experienced mild tremor in Cleveland. As of now, more than 8,000 people have reported feeling the earthquake, and most of them revealed that the intensity of the quake was weak to light.Hoogerbeets believe that critical planetary alignments and lunar geometry are causing a rise in seismic activities. As per Hoogerbeets, certain planetary alignments have the capability to destabilize the tectonic plates on the earth, and it is resulting in these earthquakes. Hoogerbeets claim that he is using an advanced system named SSGI (Solar System Geometry Index) to predict potential quakes, and he believes that it is one of the most sophisticated tools that can forecast upcoming tremors with precision.In his website post, Hoogerbeets also clarified that it is an electromagnetic force during planetary alignments which is causing the earthquakes. He also added that gravitational pull of the planets is not capable to trigger seismic activities here on earth.”From the beginning, we have stated that the most likely cause is the electromagnetic force, which is a stronger force than gravity. In fact, the gravitational force is the weakest in the Universe and is always dominated by the electromagnetic force,” added Hoogerbeets.Even though Hoogerbeets continue to make wild predictions about possible earthquakes, seismic experts have always dismissed his claims stating that no current technology is capable of predicting future earthquakes.

Molecular orbitals represent regions in a molecule where an electron is likely to be found; they are derived using mathematical formulas and are represented by cloudlike drawings with multiple nodes that are supposed to represent where electrons can go and are meant to demonstrate how molecules can share those electrons in chemical interactions or bonding. Since it was first invented in 1981, using the STM has generally been the best method available for creating images of individual atoms and their electronic properties. The STM is basically a piece of equipment with a metal appendage that has a tip width of just a few atoms. The tip is moved back and forth in the air very close to a sample being studied. Voltage is then applied allowing electrons to move between the tip and the sample. Doing so allows for measuring of the density of electrons on the surface of the material being studied which is then used to build the models.Unfortunately however, traditional STM has not been able to map orbitals of single molecules. This is because the density of electrons on the surface of an object, don’t give up the mathematical orbital nor does it have a fine enough resolution. Also there is the problem of having to place the sample on a metal surface which can hide what is going on with the molecules that comprise the sample. In the new approach the team solved the easiest part of the problem by coating the surface that the sample lays on with salt. Next, to improve resolution, they stuck a single carbon monoxide molecule on the end of the tip; this because carbon monoxide molecules have the property of having its outermost lobes paired close, with one positive the other negative phased. Such an arrangement makes the tip more sensitive to the sample material placed below it. Using this method the researchers were able to map the structure of the nodes of the molecular orbitals which allowed them to create images based on the places that held electrons. © 2011 PhysOrg.com More information: High-Resolution Molecular Orbital Imaging Using a p-Wave STM Tip, Phys. Rev. Lett. 107, 086101 (2011) DOI:10.1103/PhysRevLett.107.086101AbstractIndividual pentacene and naphthalocyanine molecules adsorbed on a bilayer of NaCl grown on Cu(111) were investigated by means of scanning tunneling microscopy using CO-functionalized tips. The images of the frontier molecular orbitals show an increased lateral resolution compared with those of the bare tip and reflect the modulus squared of the lateral gradient of the wave functions. The contrast is explained by tunneling through the p-wave orbitals of the CO molecule. Comparison with calculations using a Tersoff-Hamann approach, including s- and p-wave tip states, demonstrates the significant contribution of p-wave tip states.via Physics Viewpoint Experiments Prove Existence of Atomic Chain Anchors This document is subject to copyright.
