Materials scientist creates worlds toughest fiber by adding slip knot

first_img Journal information: arXiv Concept. The classical fibre dissipates during fracture its cumulated strain energy. In contrast, a fibre with a slider, e.g. knot, can dissipate much more energy, thanks to a sliding friction force. Credit: arXiv:1304.6658 [cond-mat.mtrl-sci] More information: The Egg of Columbus for making the world toughest fibres, arXiv:1304.6658 [cond-mat.mtrl-sci] arxiv.org/abs/1304.6658AbstractA great flourish of interest in the development of new high-strength and high-toughness materials is taking place in contemporary materials science, with the aim of surpassing the mechanical properties of commercial high-performance fibres. Recently, macroscopic buckypapers, nanotube bundles and graphene sheets have been manufactured. While their macroscopic strength remains 1-2 orders of magnitude lower than their theoretical strength, and is thus comparable to that of current commercial fibres, recent progress has been made in significantly increasing toughness. In particular, researchers have produced extremely tough nanotube fibres with toughness modulus values of up to 570 J/g, 870 J/g and very recently, including graphene, reaching 970 J/g, thus well surpassing that of spider silk (170 J/g, with a record for a giant riverine orb spider of 390 J/g and Kevlar (80 J/g). In this letter, thanks to a new paradigm based on structural mechanics rather than on materials science, we present the Egg of Columbus for making fibres with unprecedented toughness: a slider, in the simplest form just a knot, is introduced as smart frictional element to dissipate energy and in general to reshape the fibre constitutive law, showing evidence of a previously hidden toughness, strictly related to the specific strength of the material. The result is a nearly perfectly plastic constitutive law, with a shape mimicking that of spider silk. The proof of concept is experimentally realized making the world toughest fibre, increasing the toughness modulus of a commercial Endumax fibre from 44 J/g up to 1070 J/g. The maximal achievable toughness is expected for graphene, with an ideal value of 100000 J/g.via ArxivBlog Materials scientists describe a materials’ ability to take abuse in two ways: strength and toughness. Strength is measured by describing how much force it can support, while toughness is how much energy it can absorb before it breaks—hard brittle materials such as ceramics are strong, but not tough, while rubber is pretty tough, but not necessarily very strong. Pugno’s new slip knot technique—which he’s named Egg of Columbus—increases a material’s toughness, but not its strength—the underlying composition of the fiber isn’t changed—it’s more the way it’s arranged.To gain this new toughness, Pugno looked at the simple slipknot—it’s a kind of knot that grows tighter around an object when the rope used to make it is pulled. Pugno noticed that as a rope was pulled through other parts of the rope, friction occurred, slowing the pulling of the rope. When applied to single fibers, he found, the same principle caused the fiber to be able to absorb more energy than it would were it simply left as a single strand. Using this technique he was able to increase the toughness of Endumax—already the world’s toughest fiber—from 44 J/g up to 1070 J/g. Of course, because the material can only be pulled once, closing the slip knot, the increased toughness of the fiber is a single-shot deal.Pugno has also found that adding coils to the slip knots, just as is done with rope, can increase the amount of friction and therefore its toughness. In experimenting with different knots and coils, he’s also discovered that some work better on others and for that reason, is keeping this part of his research to himself, clearly believing there is money to be made from his fiber toughening technique.Of course, before that can happen, Pugno, or others will have to figure out if it’s possible to manufacturer fiber strands with tiny slip knots in them, in a cost effective manner. There’s likely to be millions of them in a single bullet-proof vest, for example.

Researchers observe the competitive doublegamma nuclear decay

first_img Double gamma rays, denoted as γγ-gama rays, occur when two γ-rays are emitted as the excited quantum state of atomic nuclei decays, simultaneously, rather than the normal one at a time. The idea was first put forth by Maria Göppert-Mayer back in the late 1930’s. A decade later famed physicists Edward Teller and colleague Gregory Breit suggested that double-gamma nuclear decay was likely the mode at play during certain states of hydrogen, when single photon emission was not possible due to angular-momentum rules. It took forty more years for the rare process to be verified in the lab. In this new work, the researchers have succeeded in actually observing the process as it occurred with a barium nucleus.To make the observation, the team used an established means for detecting single γ-rays, but added five scintillation detectors and lead lining in the chamber to reduce scattering of the rays from one of the detectors to any of the others. Then, they ran the experiment for 50 days, taking measurements along the way. It was at that point that they finally received a verifiable (by being observed by more than one of the detectors at the same time) signal at the predicted energy levels, the first ever, though other teams have been trying for several years.In addition to serving as what Gade describes as an experimental tour de-force, the work likely will be used in the future to further study the nature of atomic nuclei. Next up is to find a way to measure the energy distribution of the γγ-gama rays. © 2015 Phys.org This document is subject to copyright.

Journal information: Nature Citation: Researchers observe the competitive double-gamma nuclear decay (2015, October 15) retrieved 18 August 2019 from https://phys.org/news/2015-10-competitive-double-gamma-nuclear.html (Phys.org)—A team of researchers with Technische Universität Darmstadt, in Germany and an associate with the University of Saskatchewan in Canada has detected, for the first time, the double gamma decay of a nuclear quantum transition that vies with the allowed single γ-decay. In their paper published in the journal Nature, the team describes how they managed to capture the one in 487,805 chances phenomenon. Alexandra Gade with Michigan State University offers a News & Views piece on the work done by the team in the same journal issue, along with a brief history of the study and application of double-gamma nuclear decay. More information: Observation of the competitive double-gamma nuclear decay, Nature 526, 406–409 (15 October 2015) DOI: 10.1038/nature15543AbstractThe double-gamma (γγ)-decay of a quantum system in an excited state is a fundamental second-order process of quantum electrodynamics. In contrast to the well-known single-gamma (γ)-decay, the γγ-decay is characterized by the simultaneous emission of two γ quanta, each with a continuous energy spectrum. In nuclear physics, this exotic decay mode has only been observed for transitions between states with spin-parity quantum numbers Jπ = 0+. Single-gamma decays—the main experimental obstacle to observing the γγ-decay—are strictly forbidden for these 0+ 0+ transitions. Here we report the observation of the γγ-decay of an excited nuclear state (Jπ = 11/2−) that is directly competing with an allowed γ-decay (to ground state Jπ = 3/2+). The branching ratio of the competitive γγ-decay of the 11/2− isomer of 137Ba to the ground state relative to its single γ-decay was determined to be (2.05 ± 0.37) × 10−6. From the measured angular correlation and the shape of the energy spectra of the individual γ-rays, the contributing combinations of multipolarities of the γ radiation were determined. Transition matrix elements calculated using the quasiparticle–phonon model reproduce our measurements well. The γγ-decay rate gives access to so far unexplored important nuclear structure information, such as the generalized (off-diagonal) nuclear electric polarizabilities and magnetic susceptibilities.

Delhi Book Fair to host discussions debates

first_imgSeminars, discussions, poetry sessions and interactive programmes for children will engage visitors at the 19th edition of the Delhi Book Fair that kickstarts in the Capital on Friday, organisers said.This year, the fair will address the erosion of the reading habit as its theme, Libraries and Readerships, will focus on the role of libraries in society. Organised since 1995 by the Federation of Indian Publishers (FIP) in collaboration with the India Trade Promotion Organisation (ITPO), the nine-day fair will attract over 250 participants from India and abroad. The fair ends 31 August. Also Read – ‘Playing Jojo was emotionally exhausting’Elaborating on the theme, Ashok Gupta, general secretary of FIP said, ‘Good libraries were once considered treasures of society. They were part of us, but today reading habits of people are going down. We wanted to raise this issue and so we decided to make it the theme of our fair.”The aim is to develop neighbourhood libraries. If people work in tandem, it is possible to start from the local area and have small library set-ups,’ he said. Apart from the national capital, that dominates the publishing industry, participation of publishers from Agartala, Andhra Pradesh, Jharkhand, Kerala, Maharashtra, and international participants from the US and China will mark their presence at this business-to-business event at Pragati Maidan in central Delhi.Other than displaying treasure troves of books from various genres, there will be discussion on Library and the Reader, poetry sessions, a seminar onTales for Today’s Children: Connecting to the Roots and an interactive programme for children Sune, Jane, Khele Kahani.There will also be a debate organised for university students, on Environmental Disaster caused due to Development of Vulnerable Hilly Areas.last_img read more

Pradhan calls on Pak Prime Minister

first_imgOil Minister Dharmendra Pradhan on Wednesday called on Pakistan Premier  Nawaz Sharif, who conveyed his warm regards to Prime Minister Narendra Modi.Pradhan, who is here to attend four-nation Turkmenistan -Afghanistan-Pakistan-India (TAPI) gas pipeline meet, met Sharif on the margins of the meeting along with other TAPI oil ministers. “PM Sharif conveyed his warm regards and best wishes to PM Narendra Modi,” an official statement said later. This is the first visit by any Indian minister here after the cancellation of Foreign Secretary-level talks between the two countries in August last year. India called off the talks after the Pakistan High Commissioner in New Delhi held consultations with the Kashmiri separatists on the eve of the Indo-Pak talks.Since then the ties between the two countries have been lukewarm. Even during the SAARC Summit in Nepal last year in November, PM Modi and his Pakistani counterpart only exchanged pleasantries briefly.last_img read more

SAT quashes Sebis ban on DLF by 21 majority Chair dissents

first_imgSebi’s orders imposing similar ban on DLF’s six top officials, including Chairman K P Singh and his children Rajiv Singh and Pia Singh, were also set aside by the same majority order, passed by two members of the SAT.The SAT Presiding Officer, J P Devadhar, however passed a separate ‘minority’ order, wherein he proposed reducing the ban from three years to six months.Amid an unprecedented argument between Presiding Officer and one of the Members, Devadhar pronounced another direction for staying the operation of the SAT order for a period of four weeks “in view of the conflicting views in the matter’, but another majority order by the two members again rejected Sebi’s plea for stay on the first ‘majority decision’. In its order dated October 10, 2014, Sebi had barred DLF and six others from the capital markets for three years, alleging “active and deliberate suppression of material facts” during its over Rs 9,000-crore IPO more than seven years ago. Also Read – I-T issues 17-point checklist to trace unaccounted DeMO cashWhile DLF has already gone through five months of debarment, the SAT order will help it tap the markets for raising necessary funds for business, including through REITs and mortgage-backed securities. Welcoming the order, DLF Executive Director Rajeev Talwar said that any further decision on fund raising from the markets would be taken after the company’s board is apprised of the matter by the legal counsel and experts. DLF shares soared higher by about 10 per cent immediately after the Sebi order was quashed by SAT. The stock finally closed with a gain of 6 per cent at Rs 157.5 at the BSE. Also Read – Lanka launches ambitious tourism programme to woo Indian touristsIn their strongly-worded majority order running into 85 pages, the two SAT Members — Jog Singh and A S Lamba — ruled that Sebi “has completely failed to approach the issue in the matter pragmatically. “Viewed from any angle, the impugned order is like a troubled sea whose waters only cast up mire and dust and, therefore, the same is liable to be quashed and set aside.”They also pulled up Sebi for lapses in its investigation into the case, while stating that it was the job of merchant bankers to ensure proper disclosures in IPO documents. The order also said DLF suffered huge losses, to the tune of thousands of crores of rupees, in its market value after Sebi’s ban, and therefore such directions could not be seen as those aimed at protecting the investors’ interest. Scrip towers by over 6%; MCap up by Rs1,524 crShares of DLF surged over 6 per cent, adding Rs1,524.36 crore to its market value, after the Securities Appellate Tribunal on Friday passed a ‘majority order’ quashing the three-year market ban imposed on the realty giant by regulator Sebi.The stock soared 5.74 per cent to settle at Rs 157.50 on the BSE. During the day, it surged 9.16 per cent to Rs 162.60. On the NSE, shares of DLF jumped 6.19 per cent to end at Rs 158.70. In the process, the company’s market value rose by Rs 1,524.36 crore to Rs 28,065.36 crore. In terms of volume, 39.94 lakh shares of the company changed hands at the BSE and over two crore shares were traded at the NSE.last_img read more

72 iron ore mines in Goa can resume operations Centre

first_imgThe state was getting almost a quarter of its revenue from the mining industry before it shut down in 2012.After deciding to revoke the suspension a few days ago, the ministry issued a formal order on Saturday, but made it clear that violation of mining lease conditions would lead to immediate suspension of ECs again.The licenses of these 72 mining leases have already been renewed by the state. The environmental clearances were suspended by the then Environment Minister Jayanthi Natarajan in September 2012 following allegations of rampant illegal mining and environmental degradation in Goa. Also Read – I-T issues 17-point checklist to trace unaccounted DeMO cashThe order says the ministry has decided to “lift the abeyance of the 72 leases and they would not require any fresh EC”. It has been signed by U Sridharan, scientist, MoEF.The state’s request to lift the abeyance was examined by the ministry, taking into account recommendations of expert appraisal committee and Supreme Court’s directions, it adds. However, suspension of ECs of 18 mines located in the one-kilometre buffer zone around wildlife sanctuaries has not been revoked. Further, there are 22 mining leases — named in a list attached to the order — on the forest land, and their ECs too would remain in abeyance until they get “forest clearances”.The ministry has directed the state to develop and implement a credible mechanism to ensure that “capping of 20 million tonnes per annum of ore extraction is implemented, as suggested by the apex court”. Mining in the forest areas and export of existing ore dumps would not be allowed, it adds.last_img read more

Musical tribute to the stalwart

first_imgA musical evening titled Tere Mere Darmiyaan, dedicated to Narayan das Jaju, was a treat for the city’s Ghazal lovers. The event was held at India Habitat Centre on Saturday. Several writers, bureaucrats and artistes attended the show that brought alive the works of Jaju.The programme featured a ghazal rendition by Shashank Shekhar, an accomplished singer and composer who was recently awarded the title of Aftaab-e-Ghazal, by the government of Telangana. Shekhar perfomed  Jaju’s popular ghazals. Also Read – ‘Playing Jojo was emotionally exhausting’The highlight of the concert was the use of classical raga by Shekhar in his rendition. There was a synergy between the words of Jaju and Shekhar’s voice which was heartily appreciated by the audience. Among the ghazals which impressed connoisseurs were — Arsa Hua Ke Mar Gaya, Andar Ka Aadmi,  Bheegi Raat, Bhari Barsaaten and Lautegi Ab Barsaat Liye, Teri Jhalak Bhi. Jaju, who passed away in 2012 at the age of 70, was a multi-faceted man. He was an avid traveller and voracious reader. However, he was a poet by heart and left behind an impressive body of work. He specialised in ghazals as well as Hindi poetry. His knowledge and understanding of Indian culture and ethos was remarkable which is well reflected in his writing. Jaju wanted peace and brotherhood in the country and wrote extensively about his vision of a just and fair society. Several collections of his poetry have been published in recent times.last_img read more

TMC hits back asks Shah to pay attention to BJPled central govt

first_imgKolkata: State Finance minister Amit Mitra launched a scathing attack on BJP calling it a party of militants that is threatening people and “killing” them to grab power.Comparing the saffron party to that of militants, Mitra said: “An Emergency-like situation has been created in the nation by the BJP. They have created fear among all over the country. Amit Shah who himself is a ‘dangi’ is talking about violence in Bengal. There is no discipline in their own party because they are a militant entity.” Also Read – Heavy rain hits traffic, flightsMitra came down heavily on Shah after he addressed the BJP’s rally in Purulia on Thursday.”But it is not that easy as the people of Bengal will build up protests against it as they had brought a mass leader in the name of Mamata Banerjee to power with a huge mandate,” Mitra said adding that the people of this country have rejected them for their lack of governance and their win in only one election out of 11 that was held recently has proved it.This comes when Shah claimed that the BJP will get more than 22 seats in the forthcoming Lok Sabha polls in Bengal. He maintained in the meeting: “Trinamool Congress chief is talking about the formation of Federal Front without realising that she is losing ground fast in Bengal.” Shah alleged that more than 2 crore people were not allowed to cast their votes in the Panchayat elections. “BJP has secured the second position in the elections and in 2021 it will oust Trinamool from Bengal.” Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedRubbishing Shah’s claims of improper utilisation of funds as the Finance Commission had given Rs 3.60 lakh crore to the Mamata Banerjee government, Mitra maintained: “He (Shah) is telling a blatant lie. If the money is not reaching the grassroot level then the people of Bengal would not have voted in favour of the Mamata Banerjee government. At the same time, the state has received several awards from the Centre itself just by carrying out development works.” It is the Centre that has stopped sanctioning funds for 38 projects and reduced its share for 28. The CAG has also mentioned that more than 30 to 35 percent of debt incurred by Bengal is spent for developmental activities. “But it is the Mamata Banerjee government that is somehow continuing with the project for the benefit of the people,” he said. Attacking Shah as a “communal face”, Mitra said: “They believe in the philosophy of dictatorship leading to repeated attacks on the federal structure of the country. They cannot win an election by dividing society.””The BJP doesn’t know the culture of the state and is talking about violence here at a time when people were killed in Uttar Pradesh, Kashmir and Madhya Pradesh in large numbers,” Mitra said adding that it is shameful that he is relating explosion of bombs to Rabindranath Tagore’s songs. This comes when Shah urged party workers to fight the terror that has been unleashed by the Trinamool Congress alleging that 20 party workers had been killed in the recently concluded Panchayat elections.last_img read more

EU scraps Greece summit with bailout deal on knifeedge

first_imgThe summit had been billed as a last chance to stop Greece crashing out, but was scrapped as euro-zone finance ministers returned today to marathon talks after failing overnight to overcome distrust with Greece’s leftist government.With Greece facing growing misery from capital controls and fears its banks could collapse within days, a meeting of the leaders of the 19 countries that use the euro was still due to go ahead in Brussels on Sunday.”I have cancelled EUCO (the European Union summit) today,” European Council President Donald Tusk tweeted. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJI”Euro-summit to start at 1600 (1400 GMT) and last until we conclude talks on Greece.” The talks yesterday ended with deep divisions about whether to trust Greece’s radical Prime Minister Alexis Tsipras with a third bailout worth more than 80 billion euros (USD 89 billion), following months of wrangling.Fiscal hawks Germany floated a plan for a temporary “Grexit” from the euro while Finland reportedly decided flat out not to accept a new Greek rescue programme, causing panic. Also Read – Health remains key challenge in India’s development: KovindTheir downbeat assessment came despite Greece’s international creditors calling Athen’s new proposals a positive step forward after months of wrangling on a follow-up to two previous bailouts in 2010 and 2012 worth 240 billion euros.The proposals — including pension cuts and tax hikes that had been largely rejected by Greeks in a referendum a week ago — were approved by the Greek parliament in the early hours of Saturday.In Greece, there is growing alarm at capital controls that have closed banks and rationed cash at ATMs for nearly two weeks, leading to fears that food and medicine will soon run short. Economy Minister Giorgos Stathakis warned the restrictions will likely stay in place for “months” even if there is a deal.Greek newspapers expressed alarm, with the headline of the Eleftheros Typos in Athens saying: “The future of Greece on a razor’s edge” and asking “what will happen in the case of the nightmare of a Grexit?” The European Central Bank is providing emergency liquidity to keep Greek banks afloat but has frozen the limit, with fears that failure to reach a deal could cause it to shut off the taps completely.But a lack of trust in Greek authorities was blocking any agreement by the euro-zone ministers, who repeatedly called for further steps from Athens to show commitment to reforms.Italian Economy Minister Pier Carlo Padoan urged the Greek government to take steps as early as Monday to prove it would stick to its word.last_img read more

Bhangar imbroglio Final minutes between govt Committee likely by next week

first_imgKolkata: The “final minutes” between the state government and the Jomi, Jibika, Poribesh O Bastutantra Rakshya Committee over the implementation of the remaining work of the power grid sub-station in Bhangar is expected to take place by the next week. Most importantly, the work of the power grid sub-station will commence from the next day after the “final minutes” is signed.A senior state government official said: “Everybody is eagerly waiting for the meeting, in which the final minutes will be signed. It is hopefully going to take place in the next few days and all the stakeholders will abide by the same. They (senior members of the committee) are also discussing the matters with the people in the area to make them understand the need of the power grid sub-station there.” Also Read – Rain batters Kolkata, cripples normal lifeIt may be mentioned that a positive move with regards to bringing an end to the stalemate to set up the power grid sub-station has initiated, with the meeting held on June 23 between the representatives of committee and top brass of the South 24-Parganas district administration.They had placed some proposals before the district authorities and based on the same, necessary “modifications to the plan” was made to complete the remaining work of the power grid sub-station. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed”The work of the power grid sub-station will be carried out as per the modified plan, to which they (committee representatives) have also agreed,” the official said, adding that there were certain misconceptions about setting up of the power grid sub-station. “It has been ironed out and the representatives of the committee are trying to make the villagers understand that the state government has accepted their proposals and the four towers need to be set up for completion of the project,” the official said. It may be mentioned that 90 percent of the power grid is complete and nine out of 13 towers have already been set up. Now, the remaining 10 percent needs to be completed and the remaining four towers will also be set up. Giving importance to the sentiment of local people, some modifications, including escalation of the height of the towers, would be brought.The steps to complete the work would be taken up the day after the “final minutes” is signed. Besides the top brass of the district authorities, senior officials of the state Power department would also be present when the final minutes will be signed.last_img read more

Poor firefighting arrangement could be main reason behind blaze

first_imgKolkata: Despite repeated messages of caution by the state Fire and Emergency Services department, the lackadaisical attitude in maintaining a proper firefighting arrangement has come up as one of the many reasons behind the major fire at Bagree Market.Sovan Chatterjee, the state Fire and Emergency Services minister, said: “Officials had visited the Bagree Market, Mehta Building and such other buildings in Kolkata. The officials had cautioned them and also directed them to take necessary steps to avert such incidents of major fire.” Also Read – Rain batters Kolkata, cripples normal lifeWhen asked if those measures were carried out, Chatterjee said: “Would we see such an unfortunate incident if the necessary steps were taken?”It is learned that the building was constructed in 1955 and it is under the jurisdiction of Bagree Estates Private Limited (BEPL). Initially, it was only a three-storeyed building to which three more floors were added later, sources said.On the other hand, the Bagree Market Welfare Association with around 450 members, came into existence a year ago that had its first meeting on Saturday. Members of the association were found raising fingers at the supervising authorities for poor maintenance of the firefighting arrangement. The fire-fighters are not ruling out the possibility that the electric pump was lying defunct for the past few days, as a result of which there was no water in the reservoir from where it could be supplied to the sprinklers. It has also been alleged that sprinklers and other firefighting arrangements were installed in the building a few months ago but there wasn’t any mock drill or mock test of the same conducted. Despite repeated attempts, Radha Bagree of Bagree Estates Private Limited could not be contacted for her reaction in this connection. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAgain, during their visit, officials of the state Fire and Emergency Services department had pointed out that most spaces in the market were occupied by the traders to store goods that would lead to trouble in case a major fire breaks out. The officials had also directed them to take necessary measures in this connection.There are around 900 shops, offices and godowns in the building that is situated inside the narrow Canning Street with several overhead wires and cables causing impediment to normal functioning of the hydraulic ladders.According to a senior official of the state Fire and Emergency Services department, the situation would have turned worse if the incident had taken place during weekdays as the market remains absolutely packed with people from all across the state.The officer added that they should have taken steps for proper maintenance of the firefighting equipment at least to avoid their own loss and destruction of business.last_img read more

CM wants use of ballot papers in civic elections

first_imgKolkata: Raising questions over the use of Electronic Voting Machines (EVMs) in the recently-concluded general elections, Trinamool Congress supremo Mamata Banerjee said on Tuesday that her party will approach the state Election Commission and appeal for the use of ballots during the Panchayat and Municipal elections in the state.”We want ballots for voting and not machines to save democracy. We will be vocal with this demand from now on and our theme for July 21 Martyrs’ Day programme will be return to ballots,” Banerjee said while addressing a meeting with her councillors and senior party leaders at Nazrul Manch. The municipal polls in the state are scheduled to be held in 2020. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataShe also asserted that EVM machines in 30 percent areas in the state malfunctioned and were replaced with new ones during the elections. “Mock polls were not conducted with voters who stood in queues to cast their votes. On earlier instances, there were mock polls in 100 percent machines. But this time, it was done only in two percent of the EVMs. So who can guarantee that the rest of the machines were not programmed before being pressed for votes,” she questioned. Also Read – Lightning kills 8, injures 16 in stateA fortnight back, Banerjee in a meeting with her MPs and MLAs at the state Secretariat Nabanna had said that TMC will start a movement pressing for the return of ballots and it will be initiated from Bengal. She also urged all the 23 political parties in the Opposition to come together in support of ballot papers. Pointing out that the US has banned EVMs, she had also called for constituting a fact-finding committee to probe the issue of EVM malfunctioning and added that the BJP had spent lakhs of rupees to programme the EVMs and swing votes in their favour. The TMC chief further reiterated that the recently concluded election was based on falsehood which will be unearthed with the passage of time. She expressed her hope that soon all the Opposition parties will join TMC’s movement of shunning EVMs and using ballots for elections. It may be mentioned that the July 21 rally originated from TMC’s movement focusing on ‘no identity card, no vote’ in 2001. “This year, our theme for July 21 will be ‘no ballot no vote’. We will soon write to the state Election Commission on behalf of our municipal party and also on behalf of the government,” state Municipal Affairs minister Firhad Hakim said. Banerjee urged all her party leaders to keep a track on the preparation of the voters’ list across the state. “A lot of government employees who were affiliated with the CPI(M) continue to work at the government level even now as we have not terminated anybody from service on humanitarian grounds. I have information that a lot of genuine voters’ names have been struck off the electoral rolls. So I will urge the party machinery to keep an eye on this,” she added.last_img read more

Listening to music does not enhance creativity

first_imgListening to background music “significantly impairs” people’s ability to complete tasks testing verbal creativity, say scientists who challenge the myth that music makes us more creative. Psychologists from University of Gavle in Sweden, University of Central Lancashire and Lancaster University in the UK investigated the impact of background music on performance by presenting people with verbal insight problems that are believed to tap creativity. Also Read – Add new books to your shelfThey found that background music “significantly impaired” people’s ability to complete tasks testing verbal creativity – but there was no effect for background library noise. For example, a participant was shown three words (eg dress, dial, flower), with the requirement being to find a single associated word (in this case “Sun”) that can be combined to make a common word or phrase (ie sundress, sundial and sunflower). The researchers used three experiments involving verbal tasks in either a quiet environment or while exposed to background music with unfamiliar lyrics, instrumental music without lyrics, or music with familiar lyrics. Also Read – Over 2 hours screen time daily will make your kids impulsive”We found strong evidence of impaired performance when playing background music in comparison to quiet background conditions,” said Neil McLatchie of Lancaster University. Researchers suggest this may be because music disrupts verbal working memory. The third experiment – exposure to music with familiar lyrics – impaired creativity regardless of whether the music also boosted mood, induced a positive mood, was liked by the participants, or whether participants typically studied in the presence of music. However, there was no significant difference in performance of the verbal tasks between the quiet and library noise conditions. Researchers said this is because library noise is a “steady state” environment which is not as disruptive. The findings of the research challenge the popular notion of people that music helps enhance creativity in human beings.last_img read more

Browns OLine Coach Bob Wylies Weird Instructional Video is a Treasure

first_imgOne of the break out star from last years Hard Knocks was Browns Offensive Line coach, and old school football guy, Bob Wylie.  Wylie won the hearts of football fans as an old school, no nonsense guy railed against all the fancy stretching players in favor of just doing push ups, sit ups, and jumping jacks like they did in WWII.In addition to Hard Knocks bytes, Wylie – who has coached offensive lines since 1980 from the NFL to Winnipeg – also made an old instructional video on o-line technique that is so awesomely weird, it might be better than his Hard Knocks performance. The video, narrated in Wylie’s hard edge northeast accent uses sumo wrestlers, rhinoceros, and pigs to teach the position. He points out that gorillas naturally have perfect lineman posture, and criticizes God for sticking them in a jungle instead of blocking sweeps.The production value on this is more Home Shopping Network than Hard Knocks, but it’s right on brand.last_img read more

A SixStep Survival Guide for Search Engine Updates

first_imgNovember 29, 2011 Anyone who has suffered a sudden loss of website traffic understands the frustration of trying to adjust to search engine algorithm changes. This year alone, business owners have been scrambling to modify their sites following Google’s Panda update and a more recent change that aims to provide users with “the most up-to-date results.”But what if, instead of struggling to restore traffic after algorithm updates, you stayed ahead of the game and effectively bulletproofed your site against an unexpected plunge in visitor traffic?If you’re ready to go on the offense, here are six steps for surviving whatever algorithm changes the search engines might concoct in the coming months.1. Focus on quality, authoritative content. The algorithms search engines use take hundreds of factors into consideration when determining which sites to rank first in query results. Among them are page quality, relevance to a search query, and the number and quality of inbound links. The relative importance of these factors fluctuates as search engine algorithms become more sophisticated, resulting in the changes that throw unsuspecting webmasters for a loop.But remember what search engines value most: Providing high-quality results for their users. The “analysis of a site’s perceived value to users” is the factor that will increase most in importance in ranking algorithms, according to the 2011 Search Engine Ranking Factors, an annual survey of top search strategists from Seattle-based search engine optimization tools developer and online community SEOMoz.Related: New Google Search Update Could Spell More Trouble for Business WebsitesSo before you publish any content to your site, make sure it’s substantive and thoroughly researched to maximize its value in the eyes of your customers as well as the search engines.2. Avoid “bad” backlinks.A backlink is any link to your website from another website. It can be tempting to resort to easy-to-implement but low quality backlinks that drive traffic. But be aware that search engines are on the lookout for schemes such as the “10,000 backlinks for $10” packages you’ll see advertised across the Internet, and could possibly penalize you in future algorithm updates.Instead, publish authoritative content that people will want to share on their own sites and on social networks, which will naturally result in relevant backlinks to your site.3. Invest in your social presence. Last year, Google spokesman Matt Cutts confirmed that the search giant is using social signals, including links from Twitter and Facebook “shares,” as a ranking factor influencing where sites fall on its results pages.Related: How Apple’s Siri Could Destroy Local SEOThat means if you aren’t active on social networking sites, figure out where your readers like to hang out and set up profiles there. For best results, commit at least 20 minutes a day to sharing content and connecting with your followers on those sites.4. Be mindful of site structure and navigation.Although the definition of what good site design is has changed over time, the general principles behind proper structuring haven’t.Whether you’re building a new site or improving an existing one, maintain a “shallow” navigation structure so all pages can be accessed in three or fewer clicks. This not only makes your content more accessible to customers, it helps search engines crawl them. Make sure to eliminate duplicate content across pages and add internal links between pages so users can easily move through your site.5. Diversify web traffic sources. The old saying “don’t put all your eggs in one basket” counts double for your traffic generation strategies. If the bulk of your traffic comes from search engines, you’re in a precarious position if algorithms change in a way that lowers your rankings. You can protect your business website from this by diversifying traffic sources.Related: Ways to Build Online Traffic and Boost SEOIn addition to researching which keywords optimize your site for search engine ranking, build an email list, add social sharing buttons to your site and become more active on the social media sites where your readers live.6. Stay current on SEO-related news. This year, we’ve seen several Google Panda updates that aimed to reduce the presence of low-value “content farm” sites on search result pages, affecting an estimated 12 percent of all its search queries. Those changes occurred in addition to the hundreds of minor updates that search engines make every year to try to refine the quality of their results.Consider following search engine optimization experts on social media sites. To get a better sense of how frequently search engine algorithms change and how often major updates build on the tweaks that come before them, take a look at SEOMoz’s graphic depiction of Google Algorithm Changes. By studying these trends and making projections, you may be able to anticipate and prepare for future changes.Following these steps can help keep your business website busy even if your search traffic is affected by a future algorithm adjustment.

Sprint Shareholders Approve 216 Billion SoftBank Acquisition

first_img Growing a business sometimes requires thinking outside the box. Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now » Shareholders of Sprint Nextel Corp (S.N.) voted on Tuesday in favor of a sweetened takeover offer from SoftBank Corp (9984.T), ending a contentious takeover battle for the No. 3 U.S. wireless service provider.Japan’s SoftBank, which fought Dish Network Corp (DISH.O) to buy Sprint, now just needs approval from the Federal Communications Commission, the U.S. telecommunications regulator, to close the deal.According to Sprint, about 80 percent of its shares outstanding were voted in favor of the $21.6 billion deal that would leave SoftBank with 78 percent ownership of the company.Sprint said in a statement released after a sparsely attended meeting that it was sticking by its previous target for the deal to close in early July.On June 10 SoftBank increased its bid to $21.6 billion from $20.1 billion and raised the cash component of the deal for shareholders by $4.5 billion, trumping Dish’s bid and gaining support from Sprint’s second biggest shareholder Paulson & Co. which had previously said it preferred Dish’s bid.Dish, which made a bid for Sprint on April 15, abandoned its efforts to buy the company after SoftBank raised its bid.The SoftBank/Sprint deal would be Japan’s biggest takeover of an overseas company. SoftBank’s founder Masayoshi Son is looking to expand beyond the mature Japanese cellphone market.Sprint needs investment from SoftBank to help it pay for a network upgrade and its proposed buy out of the minority shareholders of Clearwire Corp (CLWR.O), in which Sprint already has a majority stake.Last week Sprint had to raise its offer for wireless service provider Clearwire to $5 per share from $3.40 per share to fight off a rival bid of $4.40 per share from Dish.Clearwire shareholders will vote on that deal on July 8.Sprint shares were up 10 cents or 1.45 percent to $6.96 on the New York Stock Exchange after the news.Shareholders attending the meeting said they were happy SoftBank had beaten Dish in the takeover battle.”Long term this is better for the company,” Rick Weir, a Kansas City based shareholder who is retired Sprint employee told Reuters at the meeting.John Massman, another Kansas City shareholder, said SoftBank’s financial strength won him over. He cited concerns that a Dish deal would have required Sprint to take on too much debt and could have resulted in a move of Sprint operations out of Kansas City to Dish’s headquarters outside of Denver.”I am not a big fan of foreign ownership but if Dish had gotten it a lot of jobs would have gone to Denver,” he said.(Reporting by Sinead Carew in New York and Carey Gillam; Editing by Gerald E.
