Scientists Create First NonCarbon Material with NearDiamond Hardness

first_imgResearch scientists have created the first non-carbon-based material with a hardness approaching that of diamond. Their work could have a significant impact on technologies and industries that rely on diamond as a cutting and drilling tool and abrasive. Extremely hard yet metallically conductive: Researchers develop novel material with high-tech prospects Explore further Citation: Scientists Create First Non-Carbon Material with Near-Diamond Hardness (2007, March 28) retrieved 18 August 2019 from https://phys.org/news/2007-03-scientists-non-carbon-material-near-diamond-hardness.htmlcenter_img This document is subject to copyright.

The material is a boron nitride “nanocomposite.” This means that, rather than consisting of one large continuous crystal, it is made of crystalline boron-nitride grains that are each a few to several nanometers in size. Although research groups have previously reported boron carbonitride materials, claimed to be the second and third hardest materials after diamond, the particular versions, or “phases,” of those materials were unstable at high temperatures. In industry, this is a major drawback.“The real breakthrough would be a bulk material that is hard, tough, and thermally stable, and thus ideal for cutting and drilling. We are the first to synthesize a bulk noncarbon material that fits this description,” said Natalia Dubrovinskaia, a researcher with the University of Heidelberg and the University of Bayreuth, both in Germany, to PhysOrg.com. Dubrovinskaia is the lead author of the paper describing the new material, which appears in the March 8 edition of Applied Physics Letters.For many materials composed of crystalline grains, also referred to as polycrystalline materials, there is a grain size for which the material’s hardness is optimized. This size is often in the nanometer range.Along this line of thought, Dubrovinskaia and her colleagues synthesized and conducted several experiments on a series of polycrystalline and nanocrystalline phases of boron nitride. This characterization included measuring the samples’ “Vickers hardness,” a test that assigns a hardness value to a material based on how readily it is indented by diamond. That value can be expressed in terms of the pressure applied by the diamond – using the pressure unit “pascal” – before it makes an indentation. For very hard materials that usually means billions of pascals (gigapascals, GPa). Single-crystal diamond, the hardest type, has a hardness of about 100 GPa.The boron nitride nanocomposite synthesized by Dubrovinskaia and her group displayed a maximum hardness of 85 GPa at a grain size of about 14 nanometers, and is thermally stable up to 1600 degrees Kelvin (about 2400 degrees Fahrenheit). The material’s hardness arises from two factors: the nanoscale-grain-size effect and each grain’s two-phase composition. That is, each grain has a nanoscale crystalline structure and a sub-nanoscale structure. This complex composition significantly increases the bulk material’s mechanical strength.Prior to this research, the next hardest known material after single-crystal diamond was cubic boron nitride, a single-crystal phase of the material, which has a Vickers hardness of 50 GPa. That leaves a rather large 50 GPa gap.“This gap can be filled by boron nitride nanocomposites, particularly by tuning their grain size and the compositional structure of the grains,” says Dubrovinskaia. “These materials may come to play an important role in industry.”Citation: Natalia Dubrovinskaia, Vladimir L.

Qubits and Branes Share Surprising Features

first_img Citation: Qubits and Branes Share Surprising Features (2008, July 3) retrieved 18 August 2019 from https://phys.org/news/2008-07-qubits-branes-features.html Most recently, Duff and colleagues from Imperial College London and the Institute for Research in Fundamental Sciences in Tehran, Iran, have discovered another correlation. They’ve shown that the “branes” in string theory mathematically correlate to the qubits in quantum information theory. Their study, titled “Wrapped Branes as Qubits,” is published in a recent issue of Physical Review Letters.“These relations between black holes and qubits are still mysterious,” Duff told PhysOrg.com. “The significance of this recent paper is that, by invoking branes wrapping around the extra dimensions, it resolved the puzzle of why black holes should display any kind of two-valuedness: ‘To wrap or not to wrap; that is the qubit.’”In string theory, which requires extra dimensions, branes are theoretical objects that can be used to describe parts of the universe on a quantum scale. For instance, black holes can be described by four D3-branes intersecting at an angle, which can be useful for understanding the microscopic origins of black hole entropy.In the current study, the researchers have shown that four D3-branes can also be wrapped around the six extra dimensions of space (that exist in 10-dimensional string theory) in a way that closely resembles an entangled three-qubit state. As the physicists explained, the way that each D3-brane can wrap one way or the other around dimensions resembles the two states that a qubit can have. The researchers showed that a similar correlation exists between M2-branes, which can wrap in one of three ways around dimensions, and qutrits, which have three possible states.To mathematically demonstrate this connection, the physicists used a well-known fact from quantum information theory: a three-qubit state can be described by five parameters (four real numbers and an angle). They showed how these five parameters correspond to the four D3 branes and the branes’ angle of intersection. The work adds to a growing body of papers published in the past year on correlations between entanglement and black holes (or quantum gravity). As the physicists described, these papers are building a kind of dictionary of translations between phenomena in one language to the phenomena in the other. “When two very different areas of physics share the same mathematics, one can learn new things about each field by borrowing techniques from the other,” Duff said. “This has been a two-way pay-off and we are certain that yet more correlations will be discovered.” However, no one yet knows whether there are any physical reasons underlying these mathematical coincidences. As Duff said, “an underlying physical basis, if it exists, would be an extra bonus.”Still, understanding the mathematical correlations could be enough to lead to some interesting applications in quantum information theory.“The weird kind of numbers known as octonions have fascinated both mathematicians and physicists for decades,” Duff said. “But in their recent books, both Roger Penrose and Ray Streater have written them off as ‘lost causes in physics’ because they have so far failed to find any application. However, we believe that the tripartite entanglement of seven qubits (inspired by stringy black holes) provides a way of testing octonions in the laboratory, and this might find applications in QI, for example, in cryptography.”More information: Borsten, L.; Dahanayake, D.; Duff, M.

What do black holes and entangled particles have in common? Until about a year ago, physicists thought that the two entities existed in completely separate worlds. Then, in 2007, physicist Michael Duff from Imperial College London demonstrated a correlation between the entanglement of three qubits and the entropy of a black hole. In the past year, several studies have demonstrated even more connections. This document is subject to copyright.

New holographic radar system can track high speed shells

first_img One of the costs associated with training military personnel is in the constant replacement of targets. To get around this problem, the DoD sent out a request for development of a system that would allow for shooting at “off-sets” – positions that are close enough to the target to measure hits versus misses, without damaging the actual target. To achieve good results in such a system, a trainee would need to see not just where the shells he’s firing are landing, but the trajectory they take in getting there. Such information helps in plotting where to send the next rounds so as to move ever closer to the intended target, improving accuracy in the process.To address the problem, engineers from Cambridge Consultants designed an entirely new kind of radar; one that uses 3D technology to create a realistic holographic image in real time that shows the trajectory of rounds fired as well as where they burst in the air or when they hit a target; all of this in a 360° image. More information: www.cambridgeconsultants.com/news_pr304.html Citation: New holographic radar system can track high speed shells (2011, September 23) retrieved 18 August 2019 from https://phys.org/news/2011-09-holographic-radar-track-high-shells.html 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. (PhysOrg.com) — The British firm Cambridge Consultants has announced the successful test of its new 3D holographic radar system that can track fired shells traveling up to 1000 miles per hour. The new system called the Land and Surface Target Scorer (LSTS) and developed for the U.S. Department of Defense (DoD), is expected to help lower the cost of training and hopefully defend against small high speed enemies. GPS-Based Fuze Expected To Triple Cannon’s Accuracy The biggest hurdle the team faced was in differentiating the shell it was tracking from surrounding “noise.” In real world environments, everything from moving water to other projectiles to debris fragments can produce radar hits making it difficult to discern what is what. The new system had to have a way of clearing all the other stuff away to allow the person manning the gun to see very clearly where his round was going. And that’s just what the recent demo of the system showed, an ability to track 5 inch shells being fired at a rate of one every three seconds.In addition to saving money on targets, such a system should also lower the cost of ammunition as it appears such a system would reduce training time. The DoD is also hoping to employ the new technology to help in tracking small fast moving targets, such as terrorists in a rubber dingy out to blow up portions of a ship as was done with the USS Cole in 2000.

The content is provided for information purposes only. “Super-Earths” are planets more massive than Earth but not exceeding the mass of Neptune. Although the term “super-Earth” refers only to the mass of the planet, it is also used by astronomers to describe planets bigger than Earth but smaller than the so-called “mini-Neptunes” (with a radius between two to four Earth-radii).Located only 21 light years away, GJ 625 is an M-dwarf star (spectral type M2) about 1/3 the size and mass of the sun. Such stars offer great potential in the search for alien Earth-like worlds, as low-mass rocky planets appear to be more frequent around M-dwarfs. However, finding an Earth-like planet orbiting low-mass stars is difficult due to their stellar activity. This is because signals induced by the rotation of a star can easily mimic those of planetary origin. Therefore, the signals coming from M-dwarfs tend to be comparable to those of rocky planets close to the habitable zone of their stars.Recently, a team of astronomers led by Alejandro Suarez Mascareño of the Canary Islands Institute of Astrophysics, has completed challenging studies of GJ 625, which began in 2013 and lasted over three and a half years. The observations were conducted with the High Accuracy Radial velocity Planet Searcher for the Northern hemisphere (HARPS-N) spectrograph installed at the Telescopio Nazionale Galileo at the Roque de los Muchachos Observatory on the island of La Palma, Canary Islands, Spain.The researchers analyzed 151 radial-velocity time series from HARPS-N as part of the HArps-n red Dwarf Exoplanet Survey (HADES) radial velocity program, which resulted in the discovery of a new planet.”We report the discovery of a super-Earth orbiting at the inner edge of the habitable zone of the star GJ 625 based on the analysis of the radial-velocity (RV) time series from the HARPS-N spectrograph, consisting in 151 HARPS-N measurements taken over 3.5 yr,” the paper reads.The newly found alien world, designated GJ 625 b, has a minimum mass of 2.8 Earth masses, which makes it the lightest exoplanet found around an M2 star to date. The planet orbits its host every 14.6 days at a distance of approximately 0.08 AU from the star, which is relatively close. By comparison, Mercury orbits the sun at a mean distance of 0.38 AU. The results of radial velocity measurements allowed the team to conclude that GJ 625 b is a small “super-Earth” on the inner edge of the habitable zone and has a mean surface temperature of 350 K that is very dependent on the atmospheric parameters. Moreover, the researchers assume that the newly detected exoworld might potentially host liquid water, but more observations focused on GJ 625 b’s atmosphere are required to confirm this assumption. (Phys.org)—European astronomers report the detection of a new extrasolar world several times more massive than Earth. The newly found exoplanet, classified as a so-called “super-Earth,” is circling a nearby star designated GJ 625. The researchers detailed their finding in a paper published May 18 on arXiv.org.

The host star is the quiet M2 V star GJ 625, located at 6.5 pc from the Sun. We find the presence of a second radial velocity signal in the range 74-85 days that we relate to stellar rotation after analysing the time series of Ca II H&K and Hα spectroscopic indicators, the variations of the FWHM of the CCF and and the APT2 photometric light curves. We find no evidence linking the short period radial velocity signal to any activity proxy. © 2017 Phys.orglast_img read more

The Surprising Boost You Get From Strangers

first_img“People feel more connected when they talk to strangers, like they are part of something bigger,” says Gillian Sandstrom, a psychologist and senior lecturer in the Department of Psychology at the University of Essex, in Colchester, England, who studies interactions between strangers. In research studies, Dr. Sandstrom has shown that people’s moods improve after they have a conversation with a Starbucks barista or a volunteer at the Tate Modern art museum in London. She’s also found that people are happier on days when they have more interactions with acquaintances they don’t know well and that students enjoy class more when they interact with their classmates. Sometimes a stranger—not a friend or a loved one—can significantly improve our day. A pleasant encounter with someone we don’t know, even a nonverbal one, can soothe us when no one else is around. It may get us out of our own head—a proven mood booster—and help broaden our perspective. They’re typically wrong. Dr. Sandstrom’s research shows people underestimate how much another person will like them when they talk for the first time. And in a study in which she asked participants to talk to at least one stranger a day for five days, 99% said they found at least one of the conversations pleasantly surprising, 82% said they learned something from one of the strangers, 43% exchanged contact information, and 40% had communicated with one of the strangers again, an indication they might be making friends. Read the whole story: The Wall Street Journal Sue took my hand in both of hers, patted it, and held on tight. We were five minutes into the worst turbulence I’d ever experienced—approaching Boston’s Logan International Airport in a severe winter storm—when I turned to the woman next to me and said: “Hey, would you mind chatting with me for a few minutes? I’m really nervous.” We hadn’t spoken much during the flight, other than the usual pleasantries. But my seatmate seemed friendly. And I suddenly felt desperate for a human connection. “Sure, my name is Sue,” the woman replied, smiling warmly. “What brings you to Boston?” I started to explain that I was on a business trip. Then the plane lurched violently, and I blurted out: “I might need to hold your hand, too.” And yet most people resist talking to strangers, she says. They fret about the mechanics of the conversation—how to start, maintain or stop it. They think they will blather on and disclose too much—or not talk enough. They worry they will bore the other person.last_img read more

A fashion form reinvented

first_imgHere’s to things of the past that deserve to be brought back with all there culture, heritage and splendor. Designer Niki Mahajan is presently working to revive the almost extinct craft of Lucknow – Badla. Badla is an old Lucknow embroidery where the metal is first stretched for long to get very thin, paper kind density. The strip of metal is then passed through flames to get different colours and then cut into very fine wires. These metal wires are then inserted in the fabric and beaten with a tinny hammers for hours and then embroidered. Considering the amount of time that goes into it, there are just a handful of Badla craftsmen left. To revive the glory of this beautiful metal embroidery, Mahajan has set up a unit in Lucknow where she has employed people associated with this craft and has been successful in revival of this art.last_img read more

France gets a framed taste of religious India

first_imgPoignant photos capturing the essence of Udaipur, its beautiful heritage buildings, natural beauty and particularly the expressions of religion by people of different faiths, are currently on display in Strasbourg, France.Clicked by French photographer Albert Huber, the photos are part of a month-long exhibition of pictures that showcases the sacred in the cities of Udaipur and Strasbourg.Titled ‘Seeking the Sacred’, the exhibition is the outcome of an exchange pact inked between the two cities. Also Read – ‘Playing Jojo was emotionally exhausting’‘In the historical Udaipur, I am the happy photographer. I photographed the narrow streets and living and the baroque palaces in their bountiful natural beauty,’ says Huber.The photographer who was in Udaipur in April this year says, ‘I photographed the extraordinary royal palace, the  women in a temple, the Protestants celebrating Good Friday in church and Muslims offering prayers at a mosque.’ Juxtaposing Huber’s pictures are those by Anuradha Sarup who photographed the sacred rituals of people in Strasbourg. Also Read – Leslie doing new comedy special with Netflix‘The city is one of France’s most vibrant and culturally rich cities. I captured on film the Pre-Easter ceremonies. I also shot the mosque there, which is the second largest mosque in France,’ says Sarup.The lenswoman who spent 10 days in the French city says it was a challenge for her to capture the ‘sacred’ through the historical cultural and religious identities of its people.‘Like Udaipur Strasbourg, an ancient European settlement has a living heritage. The city and its people have adapted beautifully to changing times,’ says Sarup. The photo exhibition is an activity under the Joint Co-operation Programme (JCP) signed between Indian Heritage Cities Network Foundation, UNESCO, the Udaipur Municipal Council, the city of Strasbourg and Maharana of Mewar Charitable Foundation (MMCF), Udaipur for three years from 2011.The pact aims to strengthen Udaipur’s knowledge base, develop a framework and undertake activities to preserve its heritage and develop international collaboration and partnerships for heritage-based projects in the Rajasthan city.‘The exhibition will open new avenues of understanding between people and provide access to various artists of different faiths. It will inspire creativity and stimulate international research digital knowledge exchange,’ says Mayank Gupta, Deputy Secretary, MMCF.The photo exhibition is part of a festival, which celebrated sacred music from over the world. The three-day ‘Sacred Days of Strasbourg’ inaugurated on May 23 with Hindu and Buddhist chants saw performances from 10 countries.After the exhibition closes on June 18 in Strasbourg it is scheduled to travel to Udaipur later this year and be showcased at the City Palace Museum there.Meanwhile, French photographer Huber says, ‘There is a lot I received in Udaipur and a lot more calls me back.’last_img read more

Missing Delhi resident found murdered in Sonipat

first_imgA 23-year-old youth and resident of New Delhi, who had gone missing since April 15 was found murdered in the agricultural fields of Dhundpur village of Rai sub-division, Sonipat on Saturday evening.The victim was identified as Chintan Saini, a resident of Rohini. His highly decomposed body was recovered from the wheat fields of the village. Inspector Savit Kumar, SHO of the Rai police station said that farm labourers spotted the dead body at around 5.30pm. “The body had injury marks on the face. This could have been done to mislead the police about the identity of the deceased. On searching through his clothes, we found his driving license issued from New Delhi. On enquiries, it was revealed that the victim had gone missing from New Delhi and an abduction case has also been registered,” the SHO said.After initiating preliminary investigation, the body has been sent to the civil hospital for autopsy.The victim was jobless and had got married five months ago, the SHO added.Post the filing of report, a police party from Rohini police station of New Delhi headed by an inspector had reached Sonipat. The kins of the deceased too had reached Sonipat to initiate the inquest proceedings.last_img read more

Believe it We are wired to be lazy

first_imgWhile you burn calories at the gym or while running in the neighbourhood park, our brain constantly works the opposite, looking for shortest route or choose to sit rather than stand, researchers report.A team from Simon Fraser University in Canada found that our nervous systems are remarkably adept in changing the way we move so as to expend the least amount of energy possible. In other words, humans are wired for laziness. Also Read – ‘Playing Jojo was emotionally exhausting’“We found that people readily change the way they walk — including characteristics of their gait that have been established with millions of steps over the course of their lifetime — to save quite small amounts of energy,” explained lead researcher Max Donelan. This is completely consistent with the sense that most of us have that we prefer to do things in the least effortful way, like when we choose the shortest walking path or choose to sit rather than stand. Also Read – Leslie doing new comedy special with Netflix“Even within a well-rehearsed movement like walking, the nervous system subconsciously monitors energy use and continuously re-optimises movement patterns in a constant quest to move as cheaply as possible,” Bonelan informed.To reach this conclusion, the researchers asked people to walk while they wore a robotic exoskeleton. This contraption allowed the researchers to discourage people from walking in their usual way by making it more costly to walk normally than to walk some other way. More specifically, the researchers made it more difficult for participants to swing their legs by putting resistance on the knee during normal walking, whereas the researchers eased this resistance for other ways of walking. This allowed the researchers to test whether people can sense and optimise the cost associated with their movements in real time.The experiment revealed that people adapt their step frequency to converge on a new energetic optimum very quickly — within minutes.What’s more, people do this even when the energy savings is quite small: less than 5 per cent. There is a bright side to this.“Sensing and optimising energy use that quickly and accurately is an impressive feat on the part of the nervous system. You have to be smart to be that lazy!” noted lead author Jessica Selinger.The findings, which were made by studying the energetic costs of walking, apply to most of our movements.The paper appeared in the Cell Press journal Current Biology.last_img read more

Flossing may do more harm than good

first_imgFlossing is supposedly done to get rid of pieces of food and plaque from between your teeth, which if left to fester, can cause inflammation and disease. But flossing requires a high level of dexterity and if wrongly done, will do more harm than good, according to Robin Seymour, emeritus professor of dental sciences at Newcastle University, the Daily Mail reported.Instead of removing plaque, most people end up pushing the plaque between their teeth down underneath the gums and leaving it there. Another common error is using a sawing action to drag the floss back and forth.  Also Read – ‘Playing Jojo was emotionally exhausting’This does not remove plaque effectively but it can traumatise the gums. Antiseptic mouthwashes have been shown to be particularly beneficial. Look for a mouthwash which contains cetylpyridinium chloride or CPC. It binds to proteins in the mouth and creates a protective lining which can continue working for up to 12 hours.There are around 500 different types of bacteria in the mouth and some are more sensitive to certain antibacterial agents, so a mouthwash which contains both CPC and essential oils, like the Dentyl Active range, is ideal.last_img read more

Gangasagar Mela 2019 to be free from inflammable hogla leaf huts

first_imgKolkata: In a bid to avert any incident of fire, the state government is taking all necessary moves to ensure a “hogla pata free” Gangasagar Mela in 2019.Gangasagar Mela in Sagar Island takes place in January every year, in which lakhs of pilgrims from all over the country turn up to take holy dip at the confluence of river Ganga.The state government initiates the necessary planning from September onwards to ensure a safe and secure Gangasagar Mela and a meeting with the Chief Secretary was already held in Nabanna in the last week. Also Read – Rain batters Kolkata, cripples normal lifeSources said that following direction of Chief Minister Mamata Banerjee, initiatives have been taken to make the mela “hogla pata free”. Usually, hogla leaves are used in making makeshift accommodation facilities for people who visit the place during the mela.More than 1,000 huts are required to be set up every year for accommodation of the people. But it has been pointed out that the hogla leaves highly inflammable. There was also an incident of a small fire at the Gangasagar Mela in 2017. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedThe matter came up in the meeting that was held in Nabanna last week and the concerned authorities have started carrying out the necessary work to find out an alternate material, using which the huts can be made.”Engineers of the Public Health Engineering (PHE) department, the modal department to organise the mela, are carrying out a study to finalise the material that can be used to construct the makeshift huts,” said a senior state government official, adding that it was initially thought that corrugated tin can be used to build the huts. “But it would not be that safe as it is a good conductor of electricity. Since many wires need to be laid to transmit power to the makeshift structures, using corrugated tin would not be a good option,” the official said. He further added that the PHE engineers are trying to find out a fire retardant material that can be used to construct the huts.Makeshift accommodation facilities are set up for senior administrative and police officers, media persons, volunteers and pilgrims. Hogla leaf huts lined up one after the other had been a common feature of the mela for ages. Now, with the initiative taken by the state government, it would be a safer and more secure mela for the pilgrims.last_img read more

first_imgTo unify the art, craft, and culture of Panjab (Punjab) in its true essence and spirit, 2019 brings with it the sixth edition of Mela Phulkari – which revolves around ‘Awakening of Panjab’ (Jaago Panjab). The festival will go on until February 17, 10 am – 8 pm, at India Habitat Centre.Mela Phulkari is an organic extension of 1469, the conceptual brand which showcases Panjab through its eclectic range of products that reflect Punjab and Punjabiyat in every piece. Also Read – Add new books to your shelfSpeaking about the 6th edition, Harinder Singh and Kirandeep Kaur, co-founders of 1469 said, “Time has come for Panjab to wake up and face 2019 head-on, and show the world what it is capable of.” The word ‘Jaago’ is also synonymous with a wedding tradition of waking up the community of a new bride as she readies to enter a new phase of life.” The curator of the Mela, Dr Alka Pande, highlighted how women have held an important position within the social and cultural life of Panjab since time immemorial. “Along with the tradition of musical performance of Jaago, phulkari is synonymous with the new bride, who not just inherits her mother’s phulkari, but also learns the craft from her,” added Pande.

And we, at Mela Phulkari want to highlight the beauty and importance of our first Guru’s teachings,” she stated. These strong topics are being converted into a series of art installations brought together by various designers along with the team of 1469. Each work of art has a story to narrate through the theme of #JaagoPanjab. Like the previous years, we intend to release edition of our Mela Phulkari Journal highlighting these themes through short stories, articles, and poems, informed Harinder. “In this journey of Mela Phulkari, we have been able to not only sensitise the audience to the story of Phulkari but in the process mobilise the rural women of Panjab towards progress and self-reliance,” mentioned the 1469 team. Mela Phulkari 6 has its own unique vocabulary. The overarching idea is Jaago of Panjab, which is manifested in the first-morning cry of the cock. The twelve installations are symbolic of the ‘baramasas’ or twelve months, which have been eulogized by the poets and painters over the aeons. Five beautiful and antique pieces of jewelry have been painstakingly painted in great detail on “Taat” (jute) showcasing the opulence and fertility for a new bride, beautiful “Dolus” encrusted in gold representing the prized tradition of milkmen going to every single house of the neighborhood and delivering fresh milk each day, the Kukkad as the symbolic representation of ‘Jaago Panjab’, the Pakhi (fan) covered in antique Phulkari bagh, in a way stirring movement (Jaago Panjab) – the installation in this edition open doors to the real Punjab. On February 10, don’t forget be a part of cultural programme with celebrities like Imtiaz Ali, Harshdeep Kaur, and Jassi Jasbir who will be singing and dancing to the beats of Bhangra. The cultural extravaganza will begin 3 pm onward.last_img read more

The Hiroshima Maidens Survivors of the Atomic Bomb Underwent Plastic surgery in

first_imgIn war, the ones who suffer most are the innocent, ordinary people who don’t have the power to decide about the political questions. On August 6, 1945, when the people of Hiroshima woke up, they began the day just like any other. None of them imagined that they would pay the cost of their country’s war with their lives.Those who survived the attack woke up in a destroyed city, their loved ones dead, and themselves injured and deformed.Today, there are some 200 thousand survivors of the 1945 atomic bombings in Hiroshima and Nagasaki called “hibakusha.” Translated into English, it means “explosion-affected people.”Atomic bomb mushroom clouds over Hiroshima (left) and Nagasaki (right). Photo by Binksternet CC By SA 3.0Among the survivors, there were a special group of young teenage girls whose faces were severely disfigured, their skin melted off by the ferocious heat of the blast.Sadly, the physical and emotional trauma directly reflected on their future. Most of them weren’t lucky in finding a job, and marriage was out of the question.Some of them had missing eyes or noses while their bodies were covered in burns. They were ignored and despised by society, deemed as contagious and dangerous.This led to the creation of a support group later known as the Hiroshima Maidens. Around thirty girls joined forces in order to share their loneliness and experiences.Hiroshima in the aftermath of the bombing.They were growing but there was no hope that any of them would have the chance of a decent life. So the girls decided to undergo reconstructive surgeries.But, at the time, Japan’s surgery standards were poor and there weren’t many plastic surgeons who could reconstruct the girls’ faces.The only solution was to get the surgery done abroad, someplace safe, with good surgeons. The United States. However, none of the girls had the finances for such an operation.Hiroshima victim and sponsor having coffee.

A two-year-long, laborious fundraising process began and many celebrities, including the Nobel laureate in literature, Pearl Buck, helped raise the donations.10,000 Room hotel that never had a guestIn 1953, Tanimoto corresponded with the U.S. journalist and peace activist Norman Cousins to help the Hiroshima Maidens during the series of reconstructive surgeries at Mount Sinai Hospital in New York.In May 1955, 25 young women arrived in New York from Hiroshima. A Quaker group arranged for them to stay with American host families.Their arrival was a highly publicized event. There was even a reality TV program hosted by Minister Tanimoto. It was named “This is Your Life,” and some of the girls shared their experiences. Many people joined the cause and supported it financially and morally, including the co-pilot of Enola Gay, the plane that dropped the bomb on Hiroshima, Captain Robert Lewis.Hiroshima Maidens in the United States.

Their time in America wasn’t only about giving them the “proper” physical appearances, but they learned a lot about “their enemy.” In the frequent interviews they had, many of the women said that they felt so welcomed that they couldn’t believe that such a country was the enemy of Japan. At the same time, the women actively advocated for nuclear disarmament.Nurse serving lunch to patient.

Incredible Find – Original Egon Schiele Drawing Picked up at Charity Shop

first_imgFor modern art fans, the name Egon Schiele is one of the most revered names. For one fan an unbelievable occurrence has transformed his life. Finding something of true and significant importance to the world at large at a yard sale or charity shop rarely happens. Buyers scour shelves and piles of “secondhand everything,” hoping to come across a rare book, or a signed movie poster from the 1930s, or a drawing that is by one of the old masters or modern art heroes. In New York City, the unusual has happened again.  A buyer seeking out items at a Habitat For Humanity charity thrift shop in Queens took home a print of a nude young woman reclining. He decided to take photos of the drawing and submit them to an art handler, who in turn contacted a gallery for examination. Lo and behold, the drawing is an original Egon Schiele, a leading light in Austria’s expressionist movement of the early 20th century who was a friend and protege of Gustav Klimt.“It looked old and out of shape but I loved the drawing. I loved everything about it, even the smell of that old vintage paper,” the man, who wishes to remain anonymous, wrote according to Habitat for Humanity.AdChoices广告inRead invented by Teads“When I saw the drawing, it reminded me of the way I enjoyed sketching so it got my attention instantly,” he went on to write. When he brought the drawing home, the man says his wife loved it so much that she wanted to put it up in their bathroom. Experts say the drawing is worth at least $100k and could even fetch up to $200k.Egon Schiele self-portraitJane Kellir, owner of Galerie St. Etienne in NYC, told the Smithsonian recently that she never gets excited when she hears of these finds, as she has seen plenty of “fakes and egregious copies.” But her gallery happens to specialize in German and Austrian expressionist art, so she was the logical expert to consult.The drawing found. Photo from Galerie St. EtienneSeveral things about the drawing peaked Kellir’s curiosity. First, the woman in the drawing herself is oddly posed, with her ribs protruding. Schiele was known for such poses. Secondly, the kind of ink and paper used were common in Austria in the early 20th century, which is the period in which the drawing was done. The girl is nude, and even her nose gave Kellir a clue that she was assessing a true Schiele.Related Video:Kellir said, “…you look at both the foreshortening of the rib cage and the way…that little nose is pointing up…there are very few people in the history of art who can draw like that.” Kellir estimates the drawing was done in 1918, just prior to the artist’s death. It is today worth hundreds of thousands of dollars – a very lucky find for the buyer at Habitat for Humanity.“Seated Woman with Bent Knees”, 1917, Egon SchieleSchiele’s penchant for drawing very young women in grotesque poses got him into all kinds of trouble. Consequently, he has a legacy that is complicated, even by today’s standards. The girl in the drawing is clearly young, and using models such as she caused Schiele problems on more than one occasion. This drawing is symbolic of those problems. He was once charged with kidnapping and violating a 13-year-old girl, whom he had merely helped when she ran away from home. Although the charges were dropped and proven false, the reputation stuck, but it is one Kellir says is completely unfair.“Lovers” by Egon Schiele“Present day standards are so very different than early, 20th century Austria,” she insists. However, some galleries that show his work place with it an addendum of sorts, outlining his supposed misconduct. Kellir refuses to qualify Schiele’s work in such a manner, stating instead that he is a truly great artist who died too young, and should not be judged by modern day norms.Related Article: Antiques Collector Bought Cheap “Fake” Picasso – Now Learns it could be AuthenticIt begs an age-old question: should we hold great artists of the past accountable for what we would judge to be sins today? It is a question that demands consideration of context, the times in which the artist lived. We cannot wipe out history, or we are doomed to repeat it, as the famous expression goes. If we were to do such a foolish thing, we would erase much of the world’s great art – music, painting, sculpture, and writing – right along with it.last_img read more

Better beat the Pats this year

first_imgBetter beat the Pats this yearThe Pats looked dominant this weekend in their Divisional Round domination of the Chargers, but Colin still thinks year is the best chance NFL teams are going to get to take them down.New England has obvious weaknesses, and the poorest collection of offensive weapons they’ve had since they won their first title in 2001. Even though Gronk is a shell of himself, Julian Edelman is aging, and they had uncharacteristic losses to bottom feeders, Belichick is likely to load up on reinforcements this offseason with 12 draft picks and additional cap space from Gronk’s likely retirement or release.

Tumblrs David Karp on Why NYC Beats Silicon Valley

first_imgMay 17, 2012 In the drudge match for finding top tech talent, David Karp, the 25-year-old CEO of Tumblr calls his company’s New York City home his best asset.Karp sat down with Webby Awards Executive Director David-Michel Davies to discuss the growth of the micro-blogging site and the evolution of Tumblr, among other things. The “fireside chat” was part of Internet Week New York, a festival of more than 250 tech-focused events around the city that runs through May 21.While many on the West Coast talk about the area being the future, Karp says instead that New York is where it’s at. Referring to the Big Apple, as the “heart of the creative world,” he adds that his company’s location allows him to be closer to the people that are important to Tumblr, a.k.a. creative types.Plus, its NYC setting has helped the company lure some top talent from big tech companies, boasts Karp. Half of the Tumblr team of 100 people are “relos,” or individuals that relocated to the area. Even as Apple and Facebook are offering up highly competitive packages, he says it’s become easier to sell people on Tumblr, in part, because of what the city of more than 8 million people has to offer. NYC is just plain “cooler than Palo Alto,” Karp says.Related: A Note to Young Treps: Put Down the RamenOf course it might also have to do with the company’s dazzling success. During the chat with Davies, the grey hoodie-clad Karp threw out some nuggets like how the microblogging website has more than 55 million blogs and over 17 billion pageviews each month.After signing up 75,000 new users in its first week, the platform grew amid a community of loyal hackers and designers that were already embracing bite sized media. In recent years, however, Tumblr has gone more mainstream — landing praise from individuals and brands alike, including Newsweek and The Hunger Games movie.Today Karp notes that the company’s millions of users can expect one Tumblr to be reblogged 9 times. Meanwhile, he claims that WordPress averages 0.8 comments per post.Related: From Pinterest to Gumroad, 19-year-old Sahil Lavingia on His Trek Through Silicon Valley That uptake among users, has helped the now five-year-old company reach a valuation of $800 million.Not bad for a guy that started the platform, as a means for self-expression. In 2007, Karp was hoping to participate more in the blogging process, though he didn’t fashion himself a writer.”I don’t enjoy writing,” he told the audience. But, at the time, he says, blogging platforms were fashioned towards writers requiring a witty headline and a real editorial voice. Looking to share his interests outside of the “vanilla” Facebook page, Karp came up with the idea that has grown in its popularity due to the ease of sharing texts and visuals.”The non-ambitious thing about Tumblr is that it is a tool for me,” Karp says. “I didn’t expect anyone to use it. It wasn’t intended to be viral or popular. It was just intended to be useful.”Related: Going Out Tonight? Zoom in, Point and Click As for the other uber-popular sites like Pinterest, Karp says he isn’t worried about sharing any headlines. Karp told YoungEntrepreneur.com that he tries to avoid viewing things in the industry too competitively. “For me, it’s not about wanting to dominate the market. It’s wanting to make sure we’re not wasting our time.”What do you think has most helped Tumblr rise to success? Let us know in the comments below.Should you follow @YoungTrep on Twitter? Absolutely.

What Googles New MobileFriendly Changes Mean for You

first_imgApril 7, 2015 5 min read Opinions expressed by Entrepreneur contributors are their own. Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now » Growing a business sometimes requires thinking outside the box. On February 26, Google dropped a major bomb in a seemingly-casual blog post on mobile-friendly search results. While the engine has always made mobile-readiness and the easy access of information a priority, it has now spelled out that it will use mobile-friendliness as a stronger ranking signal than ever before. It will also increase the presence of relevant app content in the search results.So what does that mean for you? Basically, if you’ve been holding out on implementing a mobile strategy for your business website, it’s time to make this a top priority. Here’s how to do it.Check your site’s mobile-friendlinessGoogle has made it easy to take the first step toward determining whether your site is set to take advantage of these new changes with its Mobile-Friendly Test. Simply open the page, enter your URL and click “Analyze.”Google will then check your site and report whether or not it’s mobile-friendly. If your site qualifies, the tool will also return a screenshot of how your site currently appears on mobile devices.If your site ranks as mobile-friendly, you’re in good shape, though you’ll still want to read through the following recommendations. Just because your current design passes Google’s test doesn’t mean that there aren’t still ways for you to improve or things you’ll want to watch out for if you go through a website redesign in the future.Related: Proceed With Caution: Should Smartphones Come With a Warning?Fixing mobile-friendliness issuesIf your site fails Google’s mobile-friendliness test, the program will report the specific issues that led to this determination.These recommendations will give you a starting place for the changes you’ll want to make to bring your site into compliance. Google also offers a helpful guide to getting started with mobile-friendly websites you can reference to help resolve these issues.However, be aware that the issues Google reports may not be the only factors influencing your website’s mobile usability. For that reason, it’s a good idea to explore all of the following steps to ensure your mobile visitors are as comfortable on your site as your desktop users.1. Is my site responsive?In the past, website developers had several options to create a mobile site version, including custom coding a separate mobile site, deploying device-specific HTML sites based on the vary HTTP header tag, or using a responsive design that automatically adjusted to account for various device sizes.Today, though, there are simply too many different device shapes and sizes for a single static mobile site to fit comfortably on all potential screens. Google’s official recommendation is now to use a responsive website design. Your developer or designer can tell you if your site uses this protocol. Or, if your mobile-friendliness test reports that your mobile viewport is not set (as above) or uses a fixed-width, there’s a good chance your site is not responsive and should be fixed ASAP.2. Are scripts or other services interfering with my site’s usability?If your desktop site makes use of pop-up lightbox scripts, exit intent banners or other similar types of technology, it’s critical that you ensure these programs are able to accommodate mobile users. There’s simply nothing more frustrating than having a banner pop up across your mobile web browser and being unable to close it.At the same time, be sure that your site avoids the use of file types like Flash that either don’t display at all or display incorrectly on some mobile sites. Google’s priority is to get people the information they want, as quickly as possible — and they can’t do that if your files are too difficult to load.Related: April 21 Is Your Last Chance for Mobile Optimization Before ‘Mobilegeddon’3. How easy is it to navigate my mobile site?In addition, remember that what looks good on your desktop website may not work as well on a mobile device. Keep all of the following considerations in mind as you evaluate your site’s mobile-friendliness.Make sure any tap targets are at least 48 CSS pixels tall/wide, and that you have at least 32 CSS pixels of both vertical and horizontal spacing between each tap target. Doing so will prevent inadvertent wrong-page clicks that can frustrate users.Use a base font with a size of at least 16 CSS pixels. Keep the number of fonts used to a minimum and maintain appropriate vertical spacing between rows of text.Adjust any graphic elements on your site that are currently using a fixed width formatting, as this will prevent your content — even when part of a responsive site design — from sizing appropriately for the viewport.Finally, even if you think you’ve set up everything perfectly, test, test and test some more. Use mobile site emulators to view your website in different sizes and layouts. Ask friends and family members to navigate from their digital devices, or invest in paid user testing that’ll record the actions and reactions of anonymous visitors to your mobile site.It may sound like a lot of work to guarantee mobile-friendliness, but it’s a vital part of keeping your visitors happy and maintaining your site’s search visibility.Related: How Microsoft Is Taking on Google on Its Home Turflast_img read more
