Another lens, a little farther up the cable then causes the light to be put back together. The result is light emerging from the end of the cable that appears to be unaltered, which means, for the little bit of space between the lenses, things have or could have gone on, with no record of it occurring.While it appears the new technology might be used for signal processing application, it appears equally likely it might be used for both good and bad purpose as well. For example, if coded messages could be hidden in a series of these cloaks, it would be mighty difficult to intercept them, making for very secure communications. On the other hand, it also seems logical to conclude that such a hidden time lag, if it could be made to pulse on and off, over and over as a data is passing through, could be used to intercept data without there being a record of it.In the demonstration, the reason that creating a temporary gap in the light in a fiber optic cable is considered to be cloaking time is because of the type of duality that exists between space and time in electromagnetic theory, which says in short, that diffraction and dispersion are symmetric in spacetime.If only the technology could be expanded to real world size, you could step between two lenses, and do anything you wish, and it would never be recorded in time; for the rest of the world, it would never have happened. Alas, it’s not to be however, the researchers point out that they don’t expect the technique could ever produce a gap that lasts any longer than 120 microseconds, not nearly enough time to do anything worth hiding.center_img Physicists Moti Fridman and colleagues at Cornell University have successfully demonstrated a so-called time cloaking device that is able to “hide” time for 15 trillionths of a second. In a paper published on arXiv, the researchers describe how they were able to cause light passing through a fiber optic cable to compress, than decompress, causing a hole or void to exist, long enough for there to be a lag between the two. More information: Demonstration of temporal cloaking, arXiv:1107.2062v1AbstractRecent research has uncovered a remarkable ability to manipulate and control electromagnetic fields to produce effects such as perfect imaging and spatial cloaking. To achieve spatial cloaking, the index of refraction is manipulated to flow light from a probe around an object in such a way that a “hole” in space is created, and it remains hidden. Alternatively, it may be desirable to cloak the occurrence of an event over a finite time period, and the idea of temporal cloaking was proposed in which the dispersion of the material is manipulated in time to produce a “time hole” in the probe beam to hide the occurrence of the event from the observer. This approach is based on accelerating and slowing down the front and rear parts, respectively, of the probe beam to create a well controlled temporal gap in which the event occurs so the probe beam is not modified in any way by the event. The probe beam is then restored to its original form by the reverse manipulation of the dispersion. Here we present an experimental demonstration of temporal cloaking by applying concepts from the time-space duality between diffraction and dispersive broadening. We characterize the performance of our temporal cloak by detecting the spectral modification of a probe beam due to an optical interaction while the cloak is turned off and on and show that the event is observed when the cloak is turned off but becomes undetectable when the cloak is turned on. These results are a significant step toward the development of full spatio-temporal cloaking. Explore furtherlast_img read more

Is a classical electrodynamics law incompatible with special relativity

first_img However, Mansuripur’s bold claim of a paradox with the Lorentz law has generated some intense criticism. One critic, Daniel Vanzella, a physics professor at the University of Sao Paulo in Sao Carlos, Brazil, has submitted a comment to Physical Review Letters arguing that the Lorentz law is perfectly compatible with special relativity, and that Mansuripur has misunderstood relativistic mechanics. The only paradox, Vanzella says, is why the high-ranking journal accepted the paper in the first place.Charge-magnet paradoxThe basis of Mansuripur’s argument is that the Lorentz law violates special relativity by producing different results in different reference frames. According to special relativity, the laws of physics – including electromagnetism – must be the same in all non-accelerating reference frames. He describes a scenario in which a magnetic dipole and a nearby electric charge are located a certain distance apart. When the magnet and the electric charge are at rest, no net force is exchanged between the two. This is because static electric charges only produce electric fields (to which the magnet is oblivious), and static magnets only produce magnetic fields (to which the static electric charge is oblivious). Both the Lorentz law and the Einstein-Laub version give the same result: the magnet experiences neither a force nor a torque from the electric charge.However, the Lorentz law gives a different result when a stationary observer watches the magnet and electric charge in a moving reference frame. Here, the observer sees the moving electric charge exert a torque on the moving magnet, causing the magnet to rotate as it tries to align itself with the electric field. The presence of this torque differs from the observation in the stationary reference frame where there is no torque.On the other hand, the Einstein-Laub formula, when combined with a corresponding torque formula, gives zero torque value for observers in both reference frames, complying with special relativity.The Lorentz law’s incompatibility with special relativity is not its only shortcoming, according to Mansuripur. Another equally important issue is the long-standing problem of “hidden momentum,” in which he shows that the Lorentz law fails to conserve momentum in certain situations involving magnetic media. In contrast, the Einstein-Laub equations show complete consistency with the conservation laws. For Mansuripur, this evidence indicates that the Einstein-Laub formula should be considered as a better way to understand classical electrodynamics. (Phys.org) — The laws of classical electromagnetism that were developed in the 19th century are the same laws that scientists use today. They include Maxwell’s four equations along with the Lorentz law, which describes the force exerted by electric and magnetic fields on charged particles. But Masud Mansuripur, a professor of Optical Sciences at The University of Arizona in Tucson, is now arguing that the Lorentz law of force is incompatible with special relativity and momentum conservation, and should be abandoned. In a recent issue of Physical Review Letters, he has suggested replacing the Lorentz law with a more general expression of electromagnetic force density, such as one developed by Albert Einstein and Jakob Laub in 1908. Best yet test of Lorentz invariance “This work provides a firm basis for all calculations of force, torque, momentum and angular momentum whenever electromagnetic fields (microwave, light, etc.) interact with material media,” Mansuripur told Phys.org. “The electromagnetic momentum and angular momentum become well-defined universal entities (i.e., the Abraham momentum), the need for ‘hidden momentum’ disappears, and satisfaction of conservation laws as well as conformity with special relativity are guaranteed.He explains that, during the past century, there has been a proliferation of equations for force and torque in the scientific literature, with scientists using several different formulas for the electromagnetic momentum. “My paper fixes the foundational equations and allows researchers to compare their experimental results against a single, well-defined theory,” he said.Quantum natureAccording to Mansuripur, the underlying reason for the difference between the Lorentz law and Einstein-Laub formula involves how each equation mathematically describes the quantum nature of electromagnetic fields and media. For its part, the Lorentz law depicts electric and magnetic dipoles as pairs of positive and negative charges or stable loops of current that interact with electromagnetic fields in terms of free and bound charges and currents. In contrast, the Einstein-Laub formula describes material media as spatio-temporal distributions of charge, current, polarization, and magnetization. Mansuripur explains why this distinction is important.“The fact that the electron orbits inside atoms and molecules are stable is a quantum-mechanical phenomenon,” he said. “Neither Maxwell’s equations nor the Lorentz law of force (and nor, for that matter, the Einstein-Laub force/torque equations) can account for the stability of the electron orbit. The fact that electrons, protons and neutrons have a magnetic moment associated with their spin angular momentum is also a relativistic quantum effect that has no explanation within classical physics. What Maxwell’s equations and the Lorentz law (or the Einstein-Laub law) do is provide formulas that describe the behavior of fields and material media as they are, without attempting to justify that behavior. The Lorentz law, however, simplifies the underlying physics by assuming that electric and magnetic dipoles can be treated as distributions of ordinary electrical charge and current. In contrast, the Einstein-Laub equation and the accompanying torque equation treat free charge, free current, electric dipoles, and magnetic dipoles as four distinct constituents of material media.“So, for example, the fact that a magnetic dipole is associated with something resembling a loop of current is a quantum mechanical effect. The Lorentz law does not ignore this fact, but it takes the resemblance to a current loop too far, treating the magnetic dipole as if it were actually a loop of ordinary current. In contrast, the Einstein-Laub formula acknowledges that magnetic dipoles exist as distinct entities – what makes them distinct is quantum mechanics, of course, but Einstein-Laub does not attempt to justify the existence of these dipoles or their nature. The Einstein-Laub formulas then provide a ‘recipe’ for calculating the force and torque on these dipoles, which turns out to be different from the ‘recipe’ provided by the Lorentz law.”No paradox?One critic of Mansuripur’s ideas, Vanzella, thinks that the paper is so flawed that it should not have been published at all. In his comment submitted to the journal, Vanzella points out that the Lorentz force can be put in a covariant form. In special relativity, a covariant law cannot lead to incompatible descriptions of the same phenomenon in different inertial reference frames. He explains that Mansuripur has incorrectly used relativistic mechanics and ignored a hidden momentum that makes the Lorentz formula predict a torque in one reference frame but not another. “This has blown way out of proportion,” Vanzella said. “Let me begin by stating the most important point: there is no incompatibility between the Lorentz force and special relativity. This is not a matter of opinion: any relativist knows that this is impossible for any specially-covariant law (as is the Lorentz force). By construction, a specially-covariant law is compatible with special relativity. This means that if it leads to a satisfactory description of a phenomenon in one inertial frame, then it leads to consistent descriptions in any inertial frame; there are no paradoxes.”He added that apparent paradoxes appear frequently when dealing with special relativity, but these paradoxes are actually due to simply missing or overlooking part of the relativistic argument. He says that a very similar “paradox” to the charge-magnet paradox, called the Trouton-Noble paradox, was presented and resolved more than 100 years ago. “In this particular case, using a current loop in a perfectly-conducting ring to model the magnet’s magnetic moment, one has to use special relativity to show that, even when the ring is at rest, the total momentum of the system is not zero (when subject to an external electric field),” he explained. “This momentum has been termed ‘hidden’ in the literature and this has led to some confusion, but let me stress that it is real momentum. Mansuripur is missing the point that this momentum is not an ad hoc invention only to solve paradoxes; its existence is forced upon us (upon Nature, actually) due to the principles of special relativity alone. In my comment I do not postulate the existence of this momentum. I simply use special relativity to calculate it; no additional hypothesis other than special relativity and the Lorentz force. Therefore, when Mansuripur dismisses this ‘hidden’ momentum he is doing exactly what I said is needed to arrive at a paradox: missing or overlooking part of the relativistic argument.”Despite his strong disagreement with Mansuripur, he emphasized that his criticism does not suggest anything against Mansuripur’s scientific credibility.“Please note that I don’t think that Mansuripur not knowing the solution of the ‘charge-magnet paradox’ (or not understanding the given solution) is that bad,” Vanzella said. “Special relativity is certainly not his expertise and confuses a lot of people, even physicists.”He also added that he’s not necessarily arguing that the Lorentz law must be the correct law of force, either, but just that special relativity cannot be used to testify against it. The question of which law is correct is an experimental issue. Still, he’s adamant that there is no paradox in this situation.“I wouldn’t even call Mansuripur’s idea ‘controversial,’” he said. “Would you call ‘controversial’ the idea that the Earth is flat? It is simply and provably wrong (I mean the claim that the Lorentz force is incompatible with special relativity).”In a response to Vanzella’s comment, also submitted to Physical Review Letters, Mansuripur has stuck to his original argument, explaining that there is no need to introduce hidden momentum, and that the Trouton-Noble paradox was subtly but significantly different than the charge-magnet paradox.Future of Einstein-LaubDespite the advantages of Einstein-Laub formula, Mansuripur acknowledges that it is not without its own problems. In 1979, physicist Iver Brevik performed an extensive review of the Einstein-Laub formula and other possible candidates for an energy-momentum tensor for the electromagnetic field. In some of the experiments, the Einstein-Laub formula did not match actual observations as closely as another formula, the Helmholtz force equation. However, Mansuripur argues that, due to the potential significance of this idea, the contrary evidence deserves a closer examination.“My colleagues and I are currently trying to identify situations where the distinction between the Lorentz law and the Einstein-Laub formulation is unambiguous, then try to conduct experiments to determine which law is operative in such situations,” he said. “Personally, I don’t attach much significance to the historical evidence against the Einstein-Laub formulation as reviewed in the paper by Brevik. The experiments were all electrostatic experiments, involving the flow of some dielectric fluid into a capacitor. The theoretical methods used to analyze the problem were extremely confusing; many approximations were made, and the Einstein-Laub formula itself was never used directly; instead they used a stress tensor associated with Einstein-Laub, which I have shown elsewhere to be incorrect.Mansuripur also plans to further investigate what he thinks has been a much overlooked distinction between the two formulas: a term that describes the force density of an electric field acting on the polarization density of a material medium. Whereas the Lorentz law uses –(del.P)E, the Einstein-Laub formula uses (P.del)E. Although the two formulations give exactly the same total force and total torque on any solid object, differences emerge when dealing with soft objects.“If applied to soft objects such as biological cells under intense illumination or droplets of oil or water in optical tweezers, the two formulas give different force and torque ‘distributions’ throughout the object,” he said. “This difference in force/torque distribution will then manifest itself in different deformations of the object under intense illumination. Our near-term goal, therefore, is to look for deformations of soft objects in optical tweezers experiments. A long-term goal is to look for observable differences between Lorentz and Einstein-Laub in magnetic materials.” This document is subject to copyright.

Researchers create methylation maps of Neanderthals and Denisovans compare them to modern

first_img Explore further (Phys.org) —A team of Israeli, Spanish and German researchers has for the first time created a map of gene expression in Neanderthals and Denisovans and has compared them with modern humans. In their paper published in the journal Science, the team describes how they applied epigentics to the study of our two closest known ancestors and discovered variations that might account for their differences in body shape and susceptibility to some modern neurological diseases. More information: Reconstructing the DNA Methylation Maps of the Neandertal and the Denisovan, Science, DOI: 10.1126/science.1250368ABSTRACTAncient DNA sequencing has recently provided high-coverage archaic human genomes. However, the evolution of epigenetic regulation along the human lineage remains largely unexplored. We reconstructed the full DNA methylation maps of the Neandertal and the Denisovan by harnessing the natural degradation processes of methylated and unmethylated cytosines. Comparing these ancient methylation maps to those of present-day humans, we identified ~2000 differentially methylated regions (DMRs). Particularly, we found substantial methylation changes in the HOXD cluster that may explain anatomical differences between archaic and present-day humans. Additionally, we found that DMRs are significantly more likely to be associated with diseases. This study provides insight into the epigenetic landscape of our closest evolutionary relatives and opens a window to explore the epigenomes of extinct species.

Scientists know that it’s not just our DNA structure that determines how we look and what we’re capable of doing, there’s another factor involved—the expression of our genes—they can be turned on or off at some point, allowing or preventing certain traits from developing. This process is known as DNA methylation—where methyl group chemicals attach to DNA and prevent them from behaving as they would otherwise. In this new effort, the researchers looked at methylation in Neanderthals and Denisovans to learn more about how they might have been different from us.Studying methylation in preserved fossils involves noting the way the methyl chemical cytosine decays over long periods of time. Unmethylated cytosines decay to one type of chemical while unmethylated cyctones decay to another. By measuring the amounts of the two resultant chemicals found in fossilized bone fragments, the researchers were able to create methylation maps of Neanderthals and Denisovans, which they then compared with similar maps for modern humans.The comparisons revealed differences in approximately 2000 different regions, though one in particular stood out—an HoxD cluster that prior research has shown plays an important role in the development of body structure—a finding that could help explain the shorter, stouter limbs (and other features) of our extinct cousins. Interestingly, the team also found that some of the highly methylated regional areas that appear in modern humans do not appear in either Neanderthals or Denisovans, regions that have been associated with neurological disorders such as schizophrenia and autism—a finding that may help shed some light on their source.Unfortunately, the maps created by the research team are still incomplete, they only had a few bone fragments to work with—they’re hoping future studies (and fossil finds) will reveal more. In the meantime, they plan to conduct similar work on other species, such as horses, to help reveal the types of methylation that occurred as they were domesticated.

Pair claim they have turned hydrogen to metal Citation: Researchers successfully transform liquid deuterium into a metal (2015, June 26) retrieved 18 August 2019 from https://phys.org/news/2015-06-successfully-liquid-deuterium-metal.html More information: Direct observation of an abrupt insulator-to-metal transition in dense liquid deuterium, Science 26 June 2015: Vol. 348 no. 6242 pp. 1455-1460. DOI: 10.1126/science.aaa7471ABSTRACTEighty years ago, it was proposed that solid hydrogen would become metallic at sufficiently high density. Despite numerous investigations, this transition has not yet been experimentally observed. More recently, there has been much interest in the analog of this predicted metallic transition in the dense liquid, due to its relevance to planetary science. Here, we show direct observation of an abrupt insulator-to-metal transition in dense liquid deuterium. Experimental determination of the location of this transition provides a much-needed benchmark for theory and may constrain the region of hydrogen-helium immiscibility and the boundary-layer pressure in standard models of the internal structure of gas-giant planets.Press release (Phys.org)—A team of researchers working at Sandia National Labs working with another team from the University of Rostock in Germany, has succeeded in squeezing liquid deuterium into becoming what appeared to be a metal. In their paper published in the journal Science, the team describes their new technique which has brought researchers closer to the ultimate goal of creating solid metallic hydrogen.

DOI: 10.1126/science.aac6626center_img Journal information: Science © 2015 Phys.org Explore further Back in 1935, a pair of researchers, Hillard Bell Huntington and Eugene Wigner first showed via theory that it should be possible to create solid metallic hydrogen—all that was needed was sufficient pressure. Since that time, various teams have attempted to prove that theory correct, but to date, none have been successful. In this new effort, the research team has developed a new way to add pressure that does not cause other problems. Other than pride, the only real benefit of pursuing the objective is the information that can be gleaned from such efforts, information that might prove useful in studying other planets, for example—it could shed light on the forces necessary to produce observed phenomenon.Up till now, the technique used to pressurize hydrogen, has been based on squeezing samples of it between two diamond tips—such experiments have shown that it is possible to get compounds rich in hydrogen to become metal-like.In this new effort, the researchers noted that using the dual diamond tip approach was unlikely to result in achieving the ultimate goal due to the problem of sample materials becoming too reactive. They chose to go another route, making use of the massive Sandia Z machine—it is capable of creating magnetic fields up to 20 mega gauss—they first pressurized a sample of liquid deuterium (a hydrogen isotope) then caused a jolt of current from the Z machine to move through an electrode, which in turn hit the front of the container holding the deuterium—that caused a shockwave to move through the sample, condensing it further. As the material was condensed, the researchers measured how well the sample reflected light, a common means for identifying a metal. As the sample was condensed, it moved from a transparent state, to one that was reflective. This, the team claims, shows that the material clearly moved from an insulator to a metal.The results by this new team are the closest yet to creating solid metallic hydrogen and add further proof that it can be done, if the right means are applied. It will also likely rekindle efforts by others to be the first to reach the goal.last_img read more

Chinese company announces development of graphene electronic paper

first_img Explore further (Phys.org)—Chinese based Guangzhou OED Technologies (makers of O-paper displays), in collaboration with another unidentified Chinese company has announced that they have developed what they are claiming is the “the world’s first graphene electronic paper.” In the announcement, the companies also claim that the product is a breakthrough that will bring e-paper to a new level. Graphene, is of course, a single layer of carbon bound together in a hexagon pattern. Its impressive conductivity properties have made it the subject of much research by many individuals and organizations around the world over the past few years. Now, in this new effort, the group at OED claims to have developed a graphene material that is suitable for use in making e-paper. Doing so, they also claim, allows for creating screens that are more bendable and that are also brighter because they will be able to display light with more intensity. They also suggest that because the end product will be carbon based, it should be cheaper to manufacture than current e-paper products which are based on metal indium. Thus far, the new material has not been publicly demonstrated, and it is still not clear how available products will be even after they move into production next year as promised. Despite advances, such as those made by engineers at MIT last year, it is still not clear if it will be possible to mass produce such a product in a defect-free manner. Also not clear is if the new material will be sold in partnership with other companies with a high profile in marketing e-readers, such as Amazon’s Kindle device.If the new e-paper proves to be as advertised, it could mark a major shift in e-reader technology—graphene, as is noted in the announcement, is a mere 0.335 nanometers thick, which would mean thinner displays, less weight, more durability and of course, much more flexibility. It seems possible that such a material could usher in a paradigm shift—from e-readers that look like tablet computers, to e-paper that looks like old-school paper, but is animated, similar to that seen in the Harry Potter movies. Or, as also mentioned in the announcement, it could lead finally to wearable smart devices.

More drama less love this Valentine

first_imgCome and witness the two plays called The Plaza Suite and Ek The Bhoot. Two different genres which vouch to take you on an emotional rush ride. Produced by Curtain Call productions, The Plaza Suite is directed by Vishesh Dhuria and Ek The Bhoot by Manil Mayank Mishra.Categorised as a Rom-Com, The Plaza Suite is composed of three acts, each involving different characters but all set in Suite 719 of New York city’s Plaza hotel. ‘It’s a tribute to Valentine’s day from my end. I am hugely inspired by Neil Simons stories. This story is also written by him. It further portrays all sorts of emotions involved in relationships. The story follows how three couples undergoing different conflicts meet on a common ground in the suite and how they find a vent to their personal issues,’ says Vishesh. The second play, Ek Tha Bhoot is a satire with a message on how God is is both the creator and the caretaker of the universe, but that doesn’t mean that human beings should just leave everything in his hands. They too have to do their part because in the end, God looks after the ones who look after themselves. Also Read – ‘Playing Jojo was emotionally exhausting’‘The play is adapted from Vijay Tendulkar’s Vitthala. We have taken the entire ideology and contemporarised it for the viability of the audience’s understanding. Though the morality bent and lesson remains the same. The major highlight being the dichotomy between the existence of god and ghosts good vs evil debate is seen in a new light. Finally I have tried to re-root and reinvent the conceptual understanding of the existing good and bad in the  society which would take a space in people’s hearts,’ says Manil.When: 14 FebruaryWhere: Akshara Theatrelast_img read more

Soon Howrah to get Khel City

first_imgKolkata: In a bid to improve infrastructure for sports activities, Khel City will be developed at Dumurjola in Howrah.While addressing the administrative review meeting in Howrah on Thursday, Chief Minister Mamata Banerjee stated the need of setting up another cricket stadium as there is only one in the state and there is demand for one more. The cricket stadiumwill also come up in the Khel City.Firhad Hakim, the state Urban Development and Municipal Affairs minister, was also present in the meeting. He said: “Survey has been conducted and a plan has also been chalked out to set up the Khel City. Spot visit has also been carried out with the Mayor.” Also Read – Heavy rain hits traffic, flightsHe further said: “All aspects of sports activities will be brought under one umbrella in the Khel City. There are some old buildings. Residents of the buildings will be rehabilitated to another place and HIT will be carrying out the task.””With setting up of the city, there will be infrastructure for cricket, football and other sports including swimming. Moreover, there will be a separate arena for players and sportsmen,” he said, adding that with development of the infrastructure, people from outside will also start flowing in. So, there will also be a hotel for their accommodation.

We must allow the same as there is only one cricket stadium in the state,” said the Chief Minister.It may be mentioned that the Mamata Banerjee government had given a 15 acre land at New Town to All India Football Federation (AIFF), to set up the National Centre for Excellence in Football. This came after the FIFA Under-17 Football World Cup.Hakim said that he will be holding discussion with Sourav Ganguly, to chalk out a plan to develop the cricket stadium.last_img read more

Friendship hinges on individual personality

Does personality modulate how a person reacts to eye contact? Can this difference be measured by brain activity? “We conducted an experiment where the participants’ electrical brain activity was recorded while they were looking at another person who was either making eye contact or had her gaze averted to the side,” said researcher Helen Uusberg from the University of Tartu in Estonia.The results showed that personality does indeed modulate the way one’s brain reacts to attention from another individual. The study appeared in the journal Neuropsychologia.last_img read more

Travellers can maximise savings by booking hotels early

first_imgSavvy travellers can save about 20 per cent on hotels across the world if they book during periods between May and July, according to a new survey.According to the TripAdvisor’s ‘Best Time to Book’ report booking a hotel within three months of the trip is the best time in Asia when travellers can save 24 per cent versus peak pricing.Also, travellers can save 19 per cent on hotel bookings made in Mumbai if they book within 3 months.The travel planning and booking site based its research on hotel booking and meta click data. They found that the best time periods to book can vary depending on the region or city where the traveller is looking to visit for summer and that for most destinations, the hotel rates change gradually over time, without dramatic increases or decreases in price. “For example, the least expensive time to book hotels in Asia is within 3 months, when travellers can save 24 per cent compared to the most expensive booking period. In comparison, for European hotels, the best time to book is 2-5 months ahead, when travellers can save 26 per cent compared to the peak period,” the research says. Also Read – ‘Playing Jojo was emotionally exhausting’The least expensive time to book hotels in the USA is within 2 months of the trip but hotel prices remain fairly consistent throughout the year, with a relatively modest potential savings of 8 per cent when booking during the least expensive time period.“For the cost conscious Indian traveller, the ‘Best time to book’ report answers the most important question – when to book your hotel stay in order to maximise your savings for summer travel this year,” says Nikhil Ganju, Country Manager, TripAdvisor India.

Doctors at SSKM perform surgery on 62yrold suffering from lifethreatening complication

first_imgKolkata: In a critical surgery, the SSKM Hospital has given a fresh lease of life to a 62-year-old patient from an obscure village in Malda who was brought in with severe abdominal pain and later diagnosed with Abdominal Aortic Aneurysm (AAA).Coming from a modest family, Sanjit Mondal could not afford the cost of surgery which would have been anything between Rs 10 and Rs 12 lakh at a top private hospital in the city. The SSKM Hospital has performed a surgery on the elderly patient completely free of cost. It has become possible due to various free health schemes introduced by Chief Minister Mamata Banerjee. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedMondal had been complaining of severe abdominal pain for quite sometime now. His family members took him to SSKM Hospital few days ago. Doctors there performed a few medical tests including CT Angiography which confirmed that the patient was suffering from Abdominal Aortic Aneurysm. The clinical tests showed that the walls of the Aorta had a swelling and the portion had already taken the shape of a small balloon due to the swelling. As a result of this, the Aorta became weak. Had there been any further delay in the operation, the patient would have died. The medical condition is called an Abdominal Aortic Aneurysm (AAA) when it happens in the part of the aorta within the abdomen. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseThe aorta is the largest blood vessel in the human body that carries fresh blood to head, arms and down to abdomen, legs and pelvis from the heart. Abdominal Aortic Aneurysm does not always cause problems but a ruptured aneurysm can be life-threatening. Therefore, a patient with such a symptom needs immediate medical intervention. Apprehending the seriousness of the ailments, doctors at the hospital made all the necessary arrangements on a war footing. A team was formed comprising doctors from the cardiology and CTVS departments. They conducted the surgery which lasted for nearly two hours. A senior doctor at the cardiology department who was part of the team said: “During the surgery, we adopted a procedure called Percutaneous Transcatheter Endovascular Aortic Repair (TEVAR) by which a mesh work was done on the portion of the Aorta that got ruptured.” The doctors who conducted the operation claimed that it was not often found in patients and that a delay in operation may prove fatal. The team of doctors did not follow the conventional surgical repair as the mortality is high. The patient was recently released from the hospital after the doctors performed CT Angiography on him only to convince themselves that the patient has recovered.last_img read more

More copy masters in Sarod

first_imgThere are more “copy masters” and fewer trendsetters among those playing the sarod these days, laments maestro Ustad Amjad Ali Khan, saying the focus for performers today is the “shining, glittering” world of television and social media. “Since they have access to content and recordings especially on YouTube, it’s easy for them to imitate any sarod player. So, now we have lots of copy masters in the country. The trendsetters are very, very rare,” the 72-year-old music guru said. Also Read – Add new books to your shelf”Globally, there are about 500 sarod players. Unfortunately, instead of learning and understanding the depth of Indian classical music, every sarod player has a very strong opinion,” he further explained being very sad about the present state. “The focus is only to perform because of the glittering, shining world of television and social media where you can post anything and say anything,” the sarod virtuoso maintained. Khan is sixth in the lineage of a family devoted to Indian classical music’s Senia Bangash Gharana. The 2001 Padma Vibushan recipient first performed when he was just six years old. Also Read – Over 2 hours screen time daily will make your kids impulsiveKhan, who was trained by his father, Gwalior court musician Hafiz Ali Khan, said he couldn’t think of doing anything other than playing the sarod as its sound had a global appeal. “It was my duty, my pleasure, my passion to carry on the family tradition,” he said, referring to the work of the generations before him and his ambition to take it forward. “I wanted to make the canvas much larger, much bigger, and be more expressive on the Sarod,” the widely-heard musician added. He also pointed to the differences between his learning days and the present day. “I didn’t have access to tape-recorders because there was no money to buy them. There was no television; One could only hear music through All India Radio. “There used to be a very important programme on Saturday night which I heard, called the National Programme of Music,” he recalled. On teaching his own sons, Amaan Ali Bangash and Ayaan Ali Bangash — themselves established names in the field of sarod — the Ustad said that it was a big responsibility.”Teaching my own sons was not my decision. They showed interest and positive signs, and then I shared everything with them,” he said. “I tried to introduce music to Amaan, my elder son, from his very early days. I tried interesting methods to teach so that he doesn’t find it difficult.” Ayaan, his younger son, soon followed in his footsteps, and as per the music maestro, both of them are on the “right track” in life. After rendering the National Anthem on sarod, they recently turned to the bhajan “Vaishnav Jan To”, which Mahatma Gandhi held close to his heart. They rendered it an an HCL concert, part of a monthly series, here last week. His association with Gandhi goes back to his 125th birth anniversary, when he played an improvised ‘Baapu Cause’ ‘raga’ at a Unesco commemoration in Paris.IANSlast_img read more

Substituting two and fourwheeler with bicycles for shortdistance trips

first_imgNew Delhi: India can save a whopping Rs 1.8 trillion annually from reduced fuel costs, travel time savings as well as health benefits from reduced air pollution levels and increased physical activity if cycles replace use of two and four wheelers for short distance trips, a new study has concluded. This figure accounts for 1.6% of India’s GDP for 2015-16. The study ‘Economic Benefits of Cycling in India: An Economic, Environmental and Social Assessment has been conducted by TERI (The Energy & Resource Institute) backed by All India Cycle Manufacturers’ Association. The study for the first time tries to find empirical evidence of the economic benefits that can accrue if Indians start using bicycles for short distance trips instead of motorized vehicles. Also Read – Add new books to your shelf The study estimates that 50% substitution of two wheeler and four-wheeler trips by bicycle under the average distance of 8 km will lead to a personal fuel savings of Rs 27 billion. Also, 50% substitution of two wheeler and four-wheeler trips under the average distance of 5 km will result in annual health benefits equivalent to Rs 1435 billion on account of increased physical activity. Similarly, 50% substitution of two-wheeler and four-wheeler trips under the average distance of 8 km can result in savings worth Rs 241 billion due to reduced air pollution. Also Read – Over 2 hours screen time daily will make your kids impulsive For marginal unskilled workers who walk to work every day, a 50% substitution of walking trips above the average distance of 3.5 km can result in travel time savings worth Rs 112 billion. Also, substituting half of short-distance motorized trips by cycling can save India more than 0.35 million tonnes in fuel annually while resulting in CO2 emission reduction of around 1 million tonnes. “Rs 1.8 trillion in direct benefit savings is a huge figure — greater than India’s entire public expenditure on healthcare. This is the first time in India that an elaborate study has tried to derive empirical evidence of the economic benefits of increasing usage of cycling. Despite its many benefits, India is witnessing a very slow growth in bicycle ownership. Specifically in cities short-distance trips which can be undertaken by bicycles are now being made by cars and two-wheelers instead. We need dedicated measures to promote widespread use of bicycles including micro-financing options, reducing GST rates on cycles to 5% from the current 12% as well as construction of adequate and safe cycling infrastructure,” says Mr. Pankaj M Munjal, president of All India Cycle Manufacturers’ Association and Chairman & MD of Hero Cycles. Bicycles in India are increasingly being used by only captive users, who do not have access to any other form of mobility. In the period between 2001 and 2011, the share of bicycle-owning households has only increased by 1% in India. The corresponding share in rural areas has increased by 3.4%, whereas in urban areas it has declined by 4.1%. Rising income levels, absence of safe cycling infrastructure, and increased affordability of motorized vehicles (especially two-wheelers) are major factors that have led to a decline in the share of bicycles. “Cycling provides inherent, incredible, and indefinite benefits in the form of zero dependence on energy sources, zero pollution, and improved health. Additionally, bicycles can provide critical support to urban and rural poor for seeking livelihood, education, and so on. While all this is common knowledge, our study has tried to quantify these benefits. Apart from better and safe cycling infrastructure, we also need to dispel the notion that bicycle is a poor man’s mode of transport. Measures to reduce the use of private vehicles such as congestion and parking pricing and awareness campaigns will also help turn people away from motorized transport,” Source TERI report. It is observed that more than 50% of the people in India use non-motorized forms of transport, such as walking and cycling, to travel to work followed by two-wheelers (18%) and buses (16%). In urban and rural India, on-foot trips account for the highest share of work trips with the share being 12% higher in rural areas. In rural areas, for meeting the daily travel requirements, workers are most dependent on cycling after walking. However, in urban areas, after walking workers are most dependent on two-wheelers. Increasing motorization in urban areas has given rise to many negative externalities such as dependence on fossil fuels, GHG emissions, congestion, pollution and the associated health impacts. In many developed countries such studies have been conducted for judicious appraisal and informed decision-making and have even resulted in the creation of national cycling plans/strategies/laws and separate funds. This study in the Indian context is a step forward in that direction.last_img read more

State government to help slum dwellers fulfill dream of living in flats

first_imgKolkata: State Municipal Affairs minister Firhad Hakim said on Tuesday that slum dwellers residing in vacant government plots can now have their own dwellings in that place.”We have instructed the Block Land Revenue Officer (BLRO) that in places where slums have come up, government land that has been lying unutilised will be leased out and dwellings can come up under the government sponsored ‘Nijo Bhumi Nijo Griho’ scheme. Houses can also be constructed under the ‘Banglar Bari’ scheme,” Hakim said, while tabling the West Bengal Thika Tenancy (Acquisition and Regulation) Amendment Bill, 2019, in the state Assembly. He stated that the decision has already received the approval of the state Cabinet. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataIt may be mentioned that over the years, most of the thika properties have either become dilapidated for various reasons or have gone under litigation, leaving no scope for development and reconstruction for improving the living conditions of the people, their safety and security. “The Bill empowers the tenant to build his own house by taking bank loans, or through the government’s ‘Banglar Bari’ Scheme,” Hakim said. He added that the dream of slum dwellers to live in flats can be fulfilled and in this context, the Bill can be regarded as historic. He asserted that sanction would also be given for G+4 buildings. He further stressed upon taking necessary measures to avoid “promoter raj” during enactment of the Act.

According to sources, the move would benefit the inhabitants and tenants of the slum areas of Burrabazar, Ahritola, Jadavpur, Chetla and Topsia, wherein they would be able to build residential buildings on their own.last_img read more

Antibiotics may up stroke risk

first_imgWomen who take antibiotics over a long period of time are at increased risk of heart attack or stroke, a study claims. The study, published in the European Heart Journal, found that women aged 60 or older who took antibiotics for two months or more had the greatest risk of cardiovascular disease, but long duration of antibiotic use was also associated with an increased risk if taken during middle age (aged 40-59). The researchers could find no increased risk from antibiotic use by younger adults aged between 20-39. Also Read – Add new books to your shelfThe possible reason why antibiotic use is linked to an increased risk of cardiovascular disease is because antibiotics alter the balance of the micro-environment in the gut, researchers said. “Antibiotic use is the most critical factor in altering the balance of microorganisms in the gut. Previous studies have shown a link between alterations in the microbiotic environment of the gut and inflammation and narrowing of the blood vessels, stroke and heart disease,” said Lu Qi, director of the Tulane University in the US. Also Read – Over 2 hours screen time daily will make your kids impulsiveFor the study, the team of researchers studied 36,429 women who took part in the Nurses’ Health Study, which has been running in the USA since 1976. The current study looked at data from 2004 to June 2012. In 2004 the women were aged 60 or older, and they were asked about their use of antibiotics when they were young (20-39), middle-aged (40-59) or older (60 and older). The researchers categorised them into four groups: those who had never taken antibiotics, those who had taken them for time periods of less than 15 days, 15 days to two months, or for two months or longer. During an average follow-up period of nearly eight years, during which time the women continued to complete questionnaires every two years, 1,056 participants developed cardiovascular disease. The researchers also found that women who used antibiotics for periods of two months or longer in late adulthood were 32 per cent more likely to develop cardiovascular disease than women who did not use antibiotics. Women who took antibiotics for longer than two months in middle age had a 28 per cent increased risk compared to women who did not. These results which were found in the research mean that among women who take antibiotics for two months or more in late adulthood, six women per 1,000 would develop a cardiovascular disease, compared to three per 1,000 among women who had not taken antibiotics. “By investigating the duration of antibiotic use in various stages of adulthood we have found an association between long-term use in middle age and later life and an increased risk of stroke and heart disease during the following eight years,” said Yoriko Heianza, a research fellow at Tulane University “This is an observational study and so it cannot show that antibiotics cause heart disease and stroke, only that there is a link between them,” Qi said. “It’s possible that women who reported more antibiotic use might be sicker in other ways that we were unable to measure, or there may be other factors that could affect the results that we have not been able take account of,” he said. “Our study suggests that antibiotics should be used only when they are absolutely needed. Considering the potentially cumulative adverse effects, the shorter time of antibiotic use the better,” he further added.last_img read more

The Unlikely Marriage and Sudden Divorce of Frank Sinatra and Mia Farrow

first_imgMia Farrow was a 99-pound former Catholic schoolgirl-turned groovy flower child, from a respected show business family. Her father was writer-director John Farrow; her mother, actress Maureen O’Sullivan (best known as “Jane” in the Tarzan movies of the 30s and 40s). Frank Sinatra was, well, the Chairman of the Board. For a few years, in the mid-60s, the two became one of the most unlikely hook-ups in Hollywood history. How exactly did it all go down?Mia Farrow photographed in 1965He started calling her “Angel Face.” Her pet names for him: “Frankie” and “Charlie Brown.” Sinatra flew Farrow to Palm Springs for the weekends on his private plane and showered her with expensive gifts. Farrow, who was younger than Sinatra’s oldest daughter Nancy, claimed that she had lost her virginity to him.The couple soon became the butt of jokes. “I always knew Frank would end up in bed with a boy,” cracked Sinatra’s ex-wife Ava Gardner. (By this time, Farrow had traded her long strands for an ultra-short pixie.).Sinatra in 1955Comedian Jackie Mason incorporated the twosome into his Vegas act, but cut the quips after bullets were fired through his hotel room door. Mia’s mother, Maureen O’Sullivan, reportedly remarked, “If he marries anyone, it should be me.”Backlash be damned, the pair got hitched in a small private ceremony in Las Vegas, on July 19, 1966. The union, however, was rocky right from the start. Sinatra would soon discover that he had met his match. Beneath her fragile appearance, Farrow was complicated, moody, and not at all intimidated by the singing legend.Mia Farrow and Frank Sinatra. Photo by Getty ImagesShe quickly became bored with Sinatra and his crowd, whose idea of a good time was knocking back martinis and hitting the casino craps tables in Vegas or watching old movies at Sinatra’s place in Palm Springs.According to one story, when Sinatra suggested that they screen one of his movies during a weekend in the desert, Farrow rolled her eyes and groaned, “Oh, no. We’ve all seen it at least five times.”She also made the mistake of dancing with Robert Kennedy at a party. Sinatra, who despised the former Attorney General, blaming him for his banishment from the White House — after the singer had worked hard to get his brother, President John Kennedy, elected — was furious.Frank Sinatra as Tony RomeBut the biggest source of contention between the two was Farrow’s refusal to abandon her film career. Sinatra had broken off his engagement to actress Juliet Prowse, two years before he met Farrow, because she refused to become a full-time wife. And now this. Eventually the couple compromised, agreeing that Farrow would make one film a year.Then, in 1968, came Farrow’s big break: the lead role in Paramount’s much-anticipated film, Rosemary’s Baby. Sinatra wasn’t thrilled but he waited for his wife to finish the project, which was filming on location in New York City, so she could join him in The Detective. Playing a small role as his mistress.Related Video: 60s And 70s Celebs Vintage TV CommercialsWhen Rosemary’s Baby fell four weeks behind schedule — not all that surprising, since director Roman Polanski was a renowned perfectionist — an impatient Sinatra began badgering his wife, ordering her to “ankle the film” (slang for “ditch the project”).Roman Polanski in Paris at the lunch of the César awards nominees.
