Munta Hena and RokonuzzamanTwo studens of Islamic University of Khusthia allegedly committed suicide in Kusthia and Jhenaidah district on Thursday, reports UNB .The deceased were Rokonuzzaman of Damurhuda upazila in Chuadanga and Munta Hena, daughter of Ashraful Alam, chairman of AL-Hadith and Islamic Studies Department of Islamic University. Both of them were students of Finance and Banking Department of Islamic University.Family sources and their classmates said Rokonuzzaman and Munta loved each other but their families did not agree to accept their relationship. Being failed to resolve the crisis, Munta committed suicide by hanging herself from the ceiling of her house in Jhenaidah district town around 8:00pm.As soon as Rokonuzzaman heard the news of Munta’s death, he committed suicide by jumping under a train at Moti Mia level crossing in Kushtia Sadar upazila, said Abdul Aziz, officer-in-charge of Poradah GRP police station.Besides, UNB Islamic university correspondent reports: IU proctor M Mahbubar Rahman said, “We are trying to find out the main reason behind the suicide of the two students.”However, the university authorities expressed deep shocked at the demise of the two students.
Catalan police officers ‘Mossos d’Esquadra’ try stop pro-referendum people from going into ‘Escola Collaso i Gil’ school on 29 September 2017 in Barcelona. Photo: AFPPolice in Catalonia had already sealed over half of the 2,315 polling stations in the region mid-Saturday to stop an independence referendum from taking place, the Spanish government said, as separatists remained determined to fight for their right to vote.Teachers, parents, students and activists in this wealthy northeastern region have leapt into action to defend the vote slated for Sunday, defying Madrid’s warnings of repercussions by occupying more than 160 schools designated as polling stations, it said.Enric Millo, the central government representative in Catalonia, told reporters 1,300 polling stations had already been sealed off.He said that 163 of those had already been occupied when they were sealed off, which meant those inside were allowed to leave but no one could go in.AFP reporters, however, visited several schools occupied by parents, students and locals where people could go in and out freely, indicating there may be more occupied buildings that have yet to be sealed off.The standoff between the central government and Catalan leaders over an independence referendum opposed by Madrid has morphed into one of the biggest crises to hit Spain since democracy was restored after the death of dictator Francisco Franco in 1975.As such, it has Spaniards the country over worried.In Spain’s major cities, Madrid, Barcelona, Sevilla, Santander, Alicante, Valencia and Malaga, thousands protested for Spanish unity.“We shouldn’t have got to this point. We’ve arrived at a point of no return,” said Fernando Cepeda, a 58-year-old engineer, a Spanish flag tied around his waist in front of Madrid’s city hall.Call to remain peacefulCatalan separatist leaders and organisers of “committees to protect the referendum” stressed that everyone must remain peaceful.In one incident, though, someone fired a pellet gun on Friday night at a group of people standing in front of an occupied high school in the Catalan town of Manlleu, lightly injuring three people, police said.The referendum has sown divisions among Catalans themselves, with the region deeply split on independence, even if a large majority want to be allowed to settle the matter in a legal vote.Authorities in Madrid have instructed police to ensure no votes are cast in a referendum that the courts have ruled unconstitutional.For days, they have been seizing electoral items such as ballot papers while prosecutors have ordered the closure of websites linked to the vote and the detention of key members of the team organising the referendum.But those for the vote have mobilised.On Friday, tractors paraded through Barcelona, some decked with the “Estelada”, the separatists’ flag of red-and-yellow stripes with a white star on a blue chevron.They and firefighters have pledged to protect polling stations.From district to district, people gathered to form “Committees to protect the referendum”, using the Telegram messaging app to get organised and urging everyone to remain peaceful, said an AFP correspondent who saw some of the messages.The move appeared to be partly coordinated by a platform of “schools open for the referendum.”Mobilisation will continueCarles Riera, a lawmaker in the regional parliament for the radical CUP party, part of Catalonia’s separatist coalition, vowed that mobilisation would continue after Sunday’s vote-if the “yes” camp won but Madrid opposed the result, as is almost certain.“We’re in a process of popular mobilisation that is going to last a while,” he told reporters.“This democratic wave, this level of auto-organisation will have to keep going for a long time to defend the republic.”On Friday, Spain’s education ministry said in a statement that head teachers in Catalonia “were not exempt from liability” if they cooperated and allowed their schools to remain open for the vote.Some schools have imagined innovative ways to circumvent an order that public spaces cannot be used for the referendum by organising leisure activities all over the weekend, from pyjama parties for the kids to volleyball games.Barcelona’s Joan Brossa high school, for instance, advertised a series of activities for Friday and Saturday, including film screenings, football matches and Zumba dance fitness classes.It remained unclear though how people would be able to enter sealed-off schools on Sunday to vote, even if they are occupied.The Mossos d’Esquadra Catalan police have warned about the risk of “disruption of public order” if efforts are made to prevent people from casting ballots.Madrid has sent thousands of extra police officers from other forces to Catalonia-which accounts for one fifth of Spain’s economy-to stop the referendum from happening.Catalan Vice-President Oriol Junqueras has said that there are alternatives for citizens to vote, without saying what they are.
EU leaders failed early Friday to narrow the east-west gap over how to deal with migrants coming to Europe and face a big task ahead to reform asylum rules by a deadline of June next year, summit participants said.During more than two hours of what one called “fierce” debate, eastern European leaders stood firm against refugee quotas which the majority adopted in 2015 as a form of solidarity with frontline states Greece and Italy.The stubborn divide contrasts with broad agreement among the leaders to continue shoring up Europe’s external borders through cooperation deals with third countries like Turkey and Libya.“Solidarity cannot exist only in the external dimension, but must also exist in the internal one,” German Chancellor Angela Merkel told reporters following the summit.“Here we still have a lot of work to do. The points of view did not change. But there is a clear task to continue working until June next year,” Merkel said.European Council President Donald Tusk irked some nations when he said in a pre-summit letter that a mandatory quota scheme for relocating refugees from frontline states was “ineffective” and “highly divisive”.Eastern European states Poland, Hungary, Slovakia and the Czech Republic have backed his approach, but Germany and others say the quotas are a necessary way of showing solidarity in the EU.Merkel’s 2015 decision to open the doors to one million asylum seekers was blamed by a number of European leaders, particularly Hungary’s Viktor Orban, for worsening the migration crisis.The quotas triggered sharp east-west division when they were adopted at the height of the migrant crisis in 2015 as a way to ease the burden on Italy and Greece, which have had more than 1.5 million people land on their shores in the last three years.The EU has since stalled on plans for a permanent mechanism for future crises, and the leaders of Poland, Hungary, the Czech Republic and Slovakia made clear their continuing opposition.“The discussion was fierce because the differences of opinion are still wide,” Dutch Prime Minister Mark Rutte said after the long dinner talks.“There’s no solution on how to find a consensus on the quotas,” Rutte said.Luxembourg Prime Minister Xavier Bettel told reporters afterwards “it is dangerous to think we can do without a permanent mechanism”.Before the summit started, the four eastern leaders offered a financial contribution of 35 million euros ($30 million) to bolster external borders.But Bettel, Rutte and others said the money cannot buy off countries that do their share to admit migrants and refugees.“What Orban is doing is shameful!” Dutch Prime Minister Mark Rutte said at the end of the summit.“If you allow that to happen, the EU becomes a place where each one does his shopping to buy what he likes,” Rutte added.‘Decide by majority’Orban has led eastern opposition to admitting refugees and migrants, saying the region will not be able to integrate them and it will face a security threat, particularly from Muslims.EU sources said there is a “window” to try to bridge the gap over sharing the migrant burden as the bloc has been under less migrant pressure for the last year or so.The June deadline for asylum reform comes as the summer weather makes Mediterranean boat crossings more likely.Italy and Greece have seen sharp declines in migrant arrivals in the last months and year as a result of EU cooperation with Libya and Turkey, but fear future crises.Tusk’s comments caused a pre-summit row with the European Commission, the executive arm of the EU, which first pushed the quota system.EU officials said over 32,000 people had been relocated under the plan, or 90 percent of those eligible. The scheme was originally meant to relocate 160,000 refugees.EU Migration Commissioner Dimitris Avramopoulos called Tusk’s remarks “unacceptable” and “anti-European”.After the summit, Rutte said: “We are worried about (Tusk’s) consensual approach.“It is important that as a last resort the council (member states) can decide by majority.”
© 2010 PhysOrg.com (PhysOrg.com) — A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced from the virtual particles that have been thought to exist in a quantum vacuum. In a paper published on arXiv, the team describes how they used a specially created circuit called a superconducting quantum interference device (SQUID) to modulate a bit of wire length at a roughly five percent of the speed of light, to produce visible “sparks” from the nothingness of a vacuum. Citation: Researchers create light from ‘almost nothing’ (2011, June 6) retrieved 18 August 2019 from https://phys.org/news/2011-06-researchers-create-light-from-almost.html Explore further More information: Observation of the Dynamical Casimir Effect in a Superconducting Circuit, arXiv:1105.4714v1 [quant-ph]AbstractOne of the most surprising predictions of modern quantum theory is that the vacuum of space is not empty. In fact, quantum theory predicts that it teems with virtual particles flitting in and out of existence. While initially a curiosity, it was quickly realized that these vacuum fluctuations had measurable consequences, for instance producing the Lamb shift of atomic spectra and modifying the magnetic moment for the electron. This type of renormalization due to vacuum fluctuations is now central to our understanding of nature. However, these effects provide indirect evidence for the existence of vacuum fluctuations. From early on, it was discussed if it might instead be possible to more directly observe the virtual particles that compose the quantum vacuum. 40 years ago, Moore suggested that a mirror undergoing relativistic motion could convert virtual photons into directly observable real photons. This effect was later named the dynamical Casimir effect (DCE). Using a superconducting circuit, we have observed the DCE for the first time. The circuit consists of a coplanar transmission line with an electrical length that can be changed at a few percent of the speed of light. The length is changed by modulating the inductance of a superconducting quantum interference device (SQUID) at high frequencies (~11 GHz). In addition to observing the creation of real photons, we observe two-mode squeezing of the emitted radiation, which is a signature of the quantum character of the generation process. The experiment shows that the Casimir effect is not just theory; named after Dutch physicist Hendrik B. G. Casimir who along with Dirk Polderfirst first proposed back in the late 1940’s, the idea of a force that existed in a vacuum; a force that should, if manipulated just right between two plates, or mirrors, result in the creation of photons.The thinking goes that in any vacuum, virtual particles come into existence and then disappear on a constant ongoing basis; and they do so in waves. The Casimir effect proposes that if two very tiny mirrors were to be placed very close together; close enough that the distance between them would be smaller than the length of some of the virtual waves, a force would be created as the number of particles outside of the space between the mirrors grows higher than the number that exists between them, causing a pull on the mirrors, dragging them closer together. The force that is created, it has been theorized, could then be used to generate photons.Later researchers proposed that the same effect could be achieved using just one mirror if it were moved back and forth very quickly; and that’s the approach the team took in the experiment. The quick movement of the mirror serves to separate pairs of virtual particles which then provide the energy to convert the virtual particles into real photons, which is what happened in the SQUID, allowing the team to see the photons that were produced.Such research, while theoretically satisfying, doesn’t really offer much in the way of practical applications, at least not at this time; but that’s not to say that new developments that arise as a result of this research couldn’t conceivably lead to something more profound, such as a means of harnessing energy from the vacuum of space to be used to push a vehicle as it travels throughout the universe.

Kolkata: Bengal government has decided to recruit 8,000 policemen apart from 565 Sub-Inspectors soon.The Cabinet has given its approval for the recruitment. The Cabinet meeting was held on Monday. It is learnt that the decision to recruit that many policemen was taken up to ensure better policing in the state.As the number of police stations has gone up in the past seven years, the state government has undertaken measures to increase manpower as well. Also Read – Rain batters Kolkata, cripples normal lifeThe new police stations were set up to reduce area of jurisdiction of a specific police station. Now, the step to add another 8,000 policemen and 565 sub-inspectors to the existing strength has been taken up for better policing.It may be recalled that the state government had earlier decided to recruit 3,000 men to raise a new battalion of Rapid Action Force (RAF).The need of raising additional unit was felt as the Centre often shows reluctance in providing central forces to control law and order situation as and when needed in the state. At the same time, the state government has taken steps to ensure security and safety of tourists. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAs a measure for ensuring security of tourists visiting Digha and Mandarmoni, the state government had created 267 posts for eight coastal police stations a fewmonths ago.After recruitment, more stress can be given on how to improve security arrangements for tourists visiting the areas.Besides creating posts and recruiting police, the state government has also created posts in the past seven years that have resulted in employment generation.Recently, the state government decided to recruit 3,673 people in different posts in departments, including Higher Education department, Personnel and Administrative Reforms, e-governance and Tribal Development department.
