Rationalizer bracelet tells traders when theyre stressed

first_img(PhysOrg.com) — Philips Electronics and the Dutch bank ABN AMRO have joined forces to develop a “Rationalizer” bracelet system that detects stress levels and displays a warning to help day-traders avoid making hasty decisions. Professor: ‘Depression is like the worst disease you can get’ (Video) Explore further Citation: ‘Rationalizer’ bracelet tells traders when they’re stressed (2009, November 17) retrieved 18 August 2019 from https://phys.org/news/2009-11-rationalizer-bracelet-traders-theyre-stressed.html Dialogues Incubator Director Paul Iske said the Rationalizer was an example of the innovative ideas being developed to add value to the customers. In this case the device should help traders look at their transactions more objectively, and warn them when irrational or unwise decisions are likely.Senior Director at Philips Design, Clive van Heerden, said emotional sensing was becoming more important in today’s digital world. He also believes there are many other possible applications, such as game controllers, intelligent cameras to interpret social situations, or even dating sites that enable you to tell who is attracted to you. © 2009 PhysOrg.com Day trading can be a hazardous occupation and rash, irrational decisions can lose the trader a lot of money. Philips and ABN AMRO decided to solve that problem by inventing a device that senses the emotions of the wearer and warns the investor to wait and carefully consider any decisions on the next transaction.The concept device was developed by Philips Design and ABN AMRO’s Dialogues Incubator, with the assistance of the VU University in Amsterdam, after research confirmed that day traders sometimes act irrationally because their actions are affected by their stress level and powerful emotions such as greed or fear. The Rationalizer consists of an “EmoBracelet” and an “EmoBowl” and incorporates sensors and signal processors designed by Philips. The EmoBracelet’s galvanic skin response sensor measures the level of emotional arousal in a similar way to a lie detector. The result is displayed on either the bracelet or the EmoBowl as a light display that intensifies and changes to reflect the wearer’s intensifying emotional arousal. At the highest emotional stress level the display has a greater number of elements moving at higher speed, and the color changes to a warning red. This document is subject to copyright.

Enhanced efficiency when determining band gap in solids

first_img Explore further Chan, a post-doc at Argonne National Lab (formerly at MIT), points out that the theory is lacking when it comes to band gaps. “The band gap problem is a well known one. However, using current methods, there is quite a bit of inaccuracy when it comes to calculating band gaps.” Band gaps in solids are important, especially if researchers want to identify the best materials for a variety of functions. The maximum efficiency of a solar cell, for example, is determined by the band gap of the material. “The inability to predict the band gap is holding back research in photovoltaics, as well as in semiconductors and thermoelectrics,” Chan points out.However, Chan thinks that a solution might have been found. Working with professor Gerbrand Ceder at MIT, it appears that a modified application of density functional theory – with a special generalization for solids – might hold the key to more accurate predictions of band gaps. The work is described in Physical Review Letters: “Efficient Band Gap Prediction for Solids.”“In the past, researchers have broken down individual electrons using a sort of itemized list of individual states. This has allowed for calculations revealing different properties, including band gaps. Unfortunately, the accuracy of the band gap predictions has been off,” Chan says. She points out that scientists know that silicon has a band gap of about 1.2 eV, but when current methods are employed to calculate the band gap, the answer is 0.7 eV. “You can see how that’s a problem if you are trying to gauge the suitability of a material for specific purposes,” she continues.To get a more accurate prediction of band gaps, Chan and Ceder created a method that involves altering the use of density functional theory so that an itemized list of individualized states is not the only consideration. “We also recognize that there are a number of interactions between electrons. So we look at the total energy, which includes these interactions,” Chan explains.Not only do Chan and Ceder make use of the total energy, but they also demonstrate that the band gap can be viewed as a property of the ground state. “This changes the way we view the band gap, seeing that it is a part of the ground state,” Chan says.Moving forward, Chan hopes that this technique can be used to identify the band gaps of different materials with more accuracy. This could prove useful in identifying the best options when creating future technology. “This work is part of the Materials Genome project started by Professor Ceder, with a goal of predicting properties of known compounds and using the knowledge to design new ones,” Chan says. “Part of that is understanding the band gap and being able to quickly determine the band gaps of various materials.”“Our method is relatively inexpensive, and could be useful when learning the properties of new materials,” Chan continues. “If someone came up with a new kind of material, predicting the band gap is not a question easily answered in the past. Hopefully our work will pave the way for easier answers in the future.” More information: M.K.Y. Chan and G. Ceder, “Efficient Band Gap Prediction for Solids,” Physical Review Letters (2010).

Researchers have poked and prodded and looked at dead cells under electron microscopes, but never before have they been able to get high resolution microscopic views of actual living brain cells as they function inside of a living animal. Now, thanks to work by physicist Stefan Hell and his colleagues at the Max Planck Institute in Germany, that dream is realized. In a paper published in Science, Hell and his team describe the workings of their marvelous discovery. Play STED time-lapse recording of a single spine at an interval of 10 seconds. The measurement includes 128 z-stacks consisting of 5 slices each. Most of the rapid remodeling of the spine head appears continuous and smooth at this frame rate. No damage is observed at the dendrite or the spine after recording a total of 640 slices. The movie was acquired in a different experiment than the spines in Fig.1. Scale bar = 1µm. Video: DOI:10.1126/science.1215369 The new microscope provides clear resolution down to 70 nanometers, which is four times that ever achieved before and is enough to allow scientists to see the actual movement of dendritic spines, which may help researches understand why they do so.It is likely that researchers will find many varied uses for the new microscope. One prominent area will almost certainly involve looking into what psychiatric drugs are really doing within synapses, perhaps leading to breakthroughs in pharmaceutical drugs that are better able to target specific illnesses.One downside to any new scientific breakthrough however, is the natural tendency of many to move from excitation, to wondering about what will come next. In this case, Hell and his team have already started contemplating ideas on ways to allow researchers to study any cell in the living brain at such high resolution, not just those that lie on the surface. © 2011 PhysOrg.com Citation: Renowned physicist invents microscope that can peer at living brain cells (2012, February 3) retrieved 18 August 2019 from https://phys.org/news/2012-02-renowned-physicist-microscope-peer-brain.html Explore further Schematic drawing of the upright STED microscope used for the experiments.

To make it easier to see what is what, the team first genetically altered the mouse to make certain brain cells fluorescent. Then, to allow for focusing exclusively on just those cells that are lit up, they added software to the microscope to blot out anything that was not lit up. The result is super high resolution real time imagery of the neurons that exist on the exterior part of a living mouse brain.

Research suggests cells communicate via biophotons

first_img Citation: Research suggests cells communicate via biophotons (2012, May 23) retrieved 18 August 2019 from https://phys.org/news/2012-05-cells-biophotons.html Egg-like cells obtained in pig fetal skin Mayburov is not alone in his thinking. Other researchers have found what they believe to be evidence of cells communicating by emitting streams of biophotons. Some have even have found what they believe are associations between the emittance of biophotons and increased cell division in plants growing in close proximity; so much so that they have measured increases of up to 30%. Others have found that biophotons emitted from older eggs in a clutch, appear to inhibit the growth of immature eggs; a form of survival of the fittest, or at least the more mature.To find out if fish eggs are able to play a similar role, Mayburov turned out the lights in his lab and recorded biophotons as they were emitted from the eggs. His aim was to see if any discernible pattern could be found, which would perhaps offer some clues as to how biophotons could be used by organisms or their cells to communicate. After much study, he says he has indeed found such a pattern and that it resembles the way we humans send binary data over noisy communications channels. The biophotons he studied he says, emit near periodic bursts of photons which could conceivably be seen and interpreted by other organisms or their cells who could then respond accordingly.Mayburov’s results don’t really prove anything of course, his results are purely speculative, yet they do suggest that there might be more to biophotons than has been previously thought. More work will have to be conducted to find answers to the many questions that still exist, such as how do cells actually create them, and if other cells in other organisms are really listening, how do they do it, and perhaps more importantly, how do they know how to respond to them? Explore further More information: Photonic Communications and Information Encoding in Biological Systems, arXiv:1205.4134v1 [q-bio.OT] arxiv.org/abs/1205.4134AbstractThe structure of optical radiation emitted by the samples of loach fish eggs is studied. It was found earlier that such radiation perform the communications between distant samples, which result in the synchronization of their development. The photon radiation in form of short quasi-periodic bursts was observed for fish and frog eggs, hence the communication mechanism can be similar to the exchange of binary encoded data in the computer nets via the noisy channels. The data analysis of fish egg radiation demonstrates that in this case the information encoding is similar to the digit to time analogue algorithm.via Arxiv Blog Journal information: arXivcenter_img © 2012 Phys.Org (Phys.org) — Biologists have long been familiar with luminescence in organisms, where plants and animals produce visible light, but more intriguing perhaps is the newer field of study centered around biophotons, whereby cells in organisms produce photons, but in numbers that are too few to be seen. How they do so and why, is an area that has come under more scrutiny of late. Now, new research by Sergey Mayburov, of the Lebedev Institute of Physics in Moscow, has uncovered a pattern in photons being generated by cells in fish eggs that gives credence to the theory that some cells use biophotons to communicate.

Researchers introduce relaxons to help describe heat flow through some crystals

first_imgPhonon propagating through a square lattice (atom displacements greatly exaggerated). Credit: Wikipedia For many years, physicists have used phonons to assist in describing the way heat moves through crystals. Thermal conductivity occurs via two processes: scattering between phonons due to atomic vibrations and disruptions to the lattice. This method has proven to be quite accurate for predicting the way heat will be conducted through many crystals, but for some, it has not worked well at all. In this new effort, the researchers added a new vibrational mode, relaxons, to improve results for such crystals.Relaxons, they explain, come about from coordinate frame changes that are different than for phonons—they decay to an equilibrium population over a well-defined lifetime. The researchers tested their new model by applying it to two materials: graphene and silicon. In silicon, the researchers found results within 2 percent of those conducted using the standard phonon approach, demonstrating success. With graphene, the researchers found different results—it read 8 times higher than that found using the standard phonon approach, which agreed with calculations performed prior to testing, indicating that it was a better approach. This suggests the new method offers a better means for making predictions of thermal conductivity when creating objects using graphene and perhaps other crystals. Adding relaxons is, in a sense, offering a new way to envision the means by which heat is conducted through certain types of crystals.The addition of relaxons to the field of heat conduction, the team notes, has implications for future theoretical studies—it could be used, perhaps, in work related to the interpretation of hydrodynamic transport, offering a new means for making predictions. The new model is also likely to have an impact on experimental research as well, particularly in mean free path spectroscopy, a new field in which researchers are looking to isolate the impact of carriers with different mean free paths to conductivity.

Credit: Li et al. ©2017 WILEY-VCH Explore further “This first-of-its-kind battery design maintains better mechanical properties compared with most reported designs using one or more rigid components that fail to meet the stretchability requirement for the entire device,” Yu told Phys.org. “Moreover, the demonstrated electrochemical performance rivals most previously reported stretchable energy systems. This novel stretchable sodium-ion battery represents a promising alternative for the next generation of energy-storage technologies in a broad range of applications.”In its current form, the battery retains nearly 90% of its capacity after 100 cycles of stretching to 50% strain. This performance is sufficient to enable the researchers to mount the stretchable battery on an elbow brace, and demonstrate that the battery continues to power an LED when the user’s arm is bent at different angles. The stretchable battery has potential applications in conformable health monitoring skin sensors, wearable communication devices, roll-up displays, and implantable medical devices.In the future, the researchers plan to make further improvements to the battery, such as extending the lifetime and scaling up the design to larger-sized batteries. They anticipate that the sponge design can also be extended to other types of devices, such as energy-harvesting devices.”Future directions will be focused on further improving the mechanical properties and electrochemical performance, along with lowering the manufacturing cost,” Yu said. (Phys.org)—Scientists have used sugar cubes as a template for synthesizing stretchable battery electrodes, which serve as a key component in newly designed stretchable yet mechanically robust sodium-ion batteries. Although there has recently been a great deal of research on stretchable batteries, usually these devices still contain some rigid components. By using electrodes templated on sugar cubes, the new battery is one of the first sodium-ion batteries whose components are all fully stretchable.

The scientists, led by Guihua Yu at the University of Texas at Austin, have published a paper on the new stretchable batteries in a recent issue of Advanced Materials.By starting with sugar cubes, the researchers were able to obtain the size, shape, and porosity needed for high-performance battery electrodes. The researchers first placed ordinary sugar cubes on top of a polymer gel in a dish. After the dish was placed in a vacuum, heated in an oven, and washed, the sugar was dissolved away and the polymer gel took its place, resulting in stretchable polymer sponges. The pores of the polymer sponges were then filled with a conductive graphene-based solution to create “sponge electrodes,” which the researchers achieved by immersing the sponges in the solution and squeezing them several times to soak it up.As the researchers explained, the sponge’s porous architecture provides a combination of stretchability, mechanical strength, fast sodium-ion transport, and large storage capacity. Tests showed that the full battery can be stretched to 50% beyond its original length, and that the strain is limited by the intrinsic properties of the polymer material. The researchers expect that modifying the polymer or developing a new nanoarchitectured elastomer could further increase the stretchability of the battery.

Brazilian President Bolsonaro May Send Army To

first_img by NPR News Philip Reeves 8.23.19 3:22pm Brazilian President Jair Bolsonaro has responded to growing international condemnation over the fires sweeping through vast swaths of the Amazon rainforest by announcing that the army may be sent in to tackle them.His comments mark a distinct shift away from his initial reaction to the crisis in which he downplayed the gravity of the situation but also caused widespread astonishment by suggesting that nongovernmental organizations may have set fires in the forest to discredit him.Faced with a spiraling environmental and political disaster, Bolsonaro plans to meet his ministers Friday to discuss how to handle the fires, after government data revealed that there are far more of them within the forest this year than last.Environmental and climate change experts say there is abundant evidence that the fires are mostly caused by humans — notably cattle ranchers — and that these illegal operators are being encouraged to clear land by the policies of Bolsonaro, who is eager for Brazil to exploit the Amazon’s agricultural and mineral wealth.Brazilians are gearing up for a weekend of protests in dozens of cities, highlighting the destruction being wrought in the rainforest and demanding that Bolsonaro’s government takes decisive action to curb the fires. Satellite data from Brazil’s National Institute of Space Research shows that there have been more than 74,000 fires this year, many of them in the Amazon. The demonstrations are “in defense of the Amazon and our future,” according to organizers.Over the past few days, international pressure has been steadily growing on Bolsonaro over his handling of the issue, especially from European leaders. A spokesman for Britain’s newly installed prime minister, Boris Johnson, said he was “deeply concerned” about the fires and “the impact of the tragic loss of these precious habitats.” French President Emmanuel Macron plans to highlight the Amazon crisis at this weekend’s G-7 summit in Biarritz, France, after sending out a tweet describing them as “an international crisis” and declaring: “Our house is burning. Literally. The Amazon rain forest — the lungs which produces 20% of the planet’s oxygen — is on fire.” Macron raised the pressure on Brazil on Friday, issuing a statement accusing Bolsonaro of lying to him about his position on climate change and announcing that France has withdrawn its support for the Mercosur trade deal between the European Union and a South American bloc that includes Brazil. Irish Prime Minister Leo Varadkar warned that Ireland would pull out of the Mercosur agreement if Brazil did not take action to protect the rainforest, according to Reuters. Bolsonaro has made clear that he considers the Amazon rainforest — 60% of which is in Brazil — to be an issue of national sovereignty, and he makes no secret of his resentment at what he deems to be foreign interference driven by a desire to hold back Brazilian agrobusiness from competing in international markets. In recent weeks, he has alienated Germany and Norway, the two main contributors to the Amazon Fund, which supports forest preservation initiatives, prompting them to withhold tens of millions of dollars. His approach has won applause from his supporters on the far right, but is also causing widespread fears among Brazilians that it is proving highly damaging to the country’s international standing and may prompt a backlash that could impact exports.”The image of the burning forest ignites public opinion and incinerates Brazil’s reputation,” wrote Ana Lucia Azevedo, a columnist for O Globo. She warns that the crisis is wrecking “the prestige and credibility” acquired by Brazil after 2005, when deforestation rates dipped sharply.Another commentator, Vinicius Torrer Freire, wrote: “Within a few months, especially in recent weeks, he has knocked down two decades of improvements in Brazil’s international image regarding the environment.”Bolsonaro argues that it is possible simultaneously to develop the Amazon and preserve the forest. His critics point to his record of relentlessly undermining institutions responsible for preserving and monitoring the Amazon. Since taking office in January, he has severely weakened government environmental enforcement organizations, by cutting budgets and laying off staff. When Brazil’s National Institute of Space Research released satellite data showing a sharp month-on-month rise in deforestation over last year, Bolsonaro dismissed this as “lies” and replaced the director with a military official.His approach is causing deep concern among professionals fighting to protect the forest, who argue that these moves send the wrong message to illegal deforesters.”They feel emboldened to carry out more deforestation,” said Fluvio Mascarenhas, who works for the Chico Mendes Institute for the Conversation of Biodiversity — a government monitoring agency — in the western state of Acre. In a recent interview with NPR, Mascarenhas expressed profound concern about the impact of Bolsonaro’s policies. “Every time you look at a satellite image of the forest, you see another little piece is missing,” he said.Copyright 2019 NPR.

first_imgKolkata: An elderly person and his wife were found dead inside their flat located at Sukantanagar in Salt Lake on Monday morning. Sleuths suspect that they had committed suicide as a note was recovered in which it was stated that the family was going through a financial crunch and could not continue with their mentally challenged son’s treatment.The couple has been identified as Ranjit Das (67) and Mamata Das (56). According to locals, on Monday, Ranjit and Mamata’s son aged around 22 years, approached them and stated that his parents have committed suicide. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedSome locals rushed to their flat and found Ranjit hanging from a ceiling fan while Mamata was lying on the bed unconsciously. Immediately, Bidhannagar South police station was informed. Sleuths sent both Ranjit and Mamata’s bodies to Bidhannagar Sub-Divisional Hospital where doctors declared both of them brought dead. Neighbours also informed that the Das family used to reside at the flat for the past six years. Their two daughters are married and their son is mentally challenged. Also Read – Bose & Gandhi: More similar than apart, says Sugata BoseLocals claimed that Ranjit and Mamata’s son used to get violent often. A few months ago, he ransacked a local shop and tried to attack a person with a sharp weapon. He also used to torture his parents. Recently, he was admitted to a hospital where his treatment was going on. Four days ago he had been released. Ranjit used to own a jewellery shop in Beliaghata which he had to sell to continue their son’s treatment. Despite selling the shop, they had to spend all their savings and even borrowed a lot of money from several people. Locals informed that their son used to beat them up often for no good reason. Sources informed that a suicide note was found from the room in which Ranjit and Mamata’s bodies were found stating that they were going through a financial crunch and thus, they were forced to commit suicide. It was also written that their daughters will be the joint owners of the flat after their death. Also, Ranjit and Mamata asked them to leave their mentally challenged brother on the road as they should not think about him anymore. Though the suicide note was recovered, sleuths are not sure about the suicide angle. This is because, apparently, there was no sign of poisoning on Mamata’s body. Sleuths suspect that Ranjit must have killed her before hanging himself. Sources informed that both of their daughters identified the handwriting in the note as Mamata’s. Police are waiting for the autopsy report.last_img read more

Food that transports you to Rajasthan

first_imgThinking about Rajasthani cuisine takes me back to the time when I was still living in Ajmer, Rajasthan. Men going out to work, while the women of the locality got together to chat and make papads and badi in the hot weather, and the vestige of neighbours coming to your doorstep to share what they have cooked for the day. Owing to their spices, the aroma of a Rajasthani meal being cooked quickly travels from the kitchen to other people’s house and you will just know that someone is making Laal Maans (red meat). The ‘laal’ in the laal maans is not an exaggeration, it actually looks red due to the abundant spices that people in Rajasthan use; it is hot, spicy, a little chatpata yet tender and juicy. Also Read – Add new books to your shelfWhat made me reminisce my time in Rajasthan was Chef Prem K Pogakula’s (Executive Chef of The Imperial, New Delhi) royal Rajasthani cuisines. His Laal maans (spicy lamb curry) is just as one would expect of Rajasthani food – spicy, tender meat which just melts in your mouth. But someone who has had actual home-cooked Rajasthani food might feel that the dishes made by the Chef are a bit on the milder side because, as said by the Chef, “not all the guests are used to hot, spicy food and hence, we have toned down the hotness and made a few twists to the authentic Rajasthani cuisines.” Also Read – Over 2 hours screen time daily will make your kids impulsiveApart from the laal maans, the Chef’s Mirchi Vada (crispy fried green peppers, stuffed with aloo masala and served with tangy green chutney) was truly royal in its taste. Mirchi Vada and green dhaniya (coriander) chutney is a street snack in Rajasthan which tastes much better when coupled with a hot, sweet tea; you could go on and on eating the vada without realising that you are having green peppers. Thanks to the Chef, a similar feeling came when I had the Mirchi Vada at Daniell’s Tavern, The Imperial. Their Dhaurasi Taffri (fresh prawns marinated with hung curd, garlic and chilli), Khad murgh (traditional baked chicken), Makki ki Seekh (minced corn infused with some special spices) and Maas ke sule (tender lamb picatta marinated with home ground spices and cooked over iron griddle) were good but lacked the authenticity of Rajasthan – maybe because of how common these cuisines are now. But every foodie’s favourite Rajasthani dish – Dal Baati Churma – was simply scrumptious. The Dal was well-cooked and a little tangy, the Baati were in perfect shape and the Churma was finely roasted; when had together, these three just gave a burst of tangy, sweet and little sour flavours in my mouth. The Chefs at Daniell’s Tavern serve a grande Rajasthani Thali with Laal Maans, rice, Govind Gatte, Khatto Murgh, Tawa Macchi, Paneer ka Sweta, Aloo Mangodi ki Subji, Gatte Pulao, Dal Baati Churma, and Jowar and Bajre ki Roti to make a delectable Rajasthani meal. One might be tempted to go for the sweets, but tread carefully, as, after the meal, the sweets might just get too sweet for your palate.last_img read more

Heavy rain likely in coastal Bengal as Fani gathers steam

first_imgKolkata: The cyclone ‘Fani’, which is currently located over Bay of Bengal at 1,170 km Southwest of the city, is expected to gain strength in the next 24 hours and likely to bring heavy showers in the coastal districts of Bengal.The state government has already issued an alert asking fishermen not to voyage into the sea from May 2 and those who have already sailed have been asked to return within the evening of May 1 as a strong wind is set to hit the South Bengal districts on May 2. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataThe state government has also asked the East Midnapore district administration to take adequate preventive measures in this regard. Senior administrative officials of the district issued instructions saying that a strong vigil will be conducted on the beaches of Digha, Mandarmani and other coastal areas, to ensure that no visitors bathe in the sea on May 2 and May 3 as it will remain turbulent. The district administration has also asked all the fishing organisations not to sail any fishing boats during this period. All watersports activities in beaches will be shut down in the wake of the cyclonic storm as well. Also Read – Lightning kills 8, injures 16 in stateThe Regional Meteorological Centre at Alipore said heavy rainfall will lash various South Bengal districts, including the city, between May 3 and 4. The districts like North 24-Parganas, South 24-Parganas, East and West Midnapore, Jhargram, Kolkata, Howrah and Hooghly will receive heavy to very heavy rainfall. On May 2 there may be light rainfall in the coastal districts. A gusty wind with an average speed of 60-85 km/h will be sweeping through various South Bengal districts on May 3 and 4. In some coastal areas, the wind speed may go up to 100 km/h. Sanjib Bandyopadhyay, deputy director general of the Regional Meteorological Centre at Alipore, said on Tuesday: “The cyclone ‘Fani’ will intensify in the next 24 hours, as a result of which various South Bengal districts will receive heavy rainfall along with strong wind. Some of the North Bengal districts will also witness rainfall and strong breeze. The cyclone will initially advance in the Northwest direction and take a sudden turn towards Northeast on May 1.” It may be mentioned here that the city and various South Bengal districts have been facing a hot and humid spell for quite some time. Until recently, there was no system in the region that could trigger a thunderstorm. Warm winds have been blowing into Gangetic Bengal from Northwest and Central India, leading to a heat-wave like condition in Bankura, Purulia, Birbhum and Jhargram.last_img read more

Calcutta Univ caps hike in number of college seats

first_imgKolkata: To address the issue of vacant seats in a number of its affiliated colleges, even after the completion of undergraduate admission the Calcutta University syndicate on Thursday decided not to allow any college to increase its seats in an illogical manner.”No colleges will be allowed to increase its seat beyond 10 percent in any subject in Honours and 15 percent in any subject for admission in general course. We have conducted a detailed survey of the admission pursued by various colleges and have found out that seats lie vacant in certain subjects in a college as they do little homework regarding demand of students,” said Sonali Chakravarti Banerjee, Vice-Chancellor of CU. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataSources in the CU syndicate informed that a number of colleges which includes around 10 in the city have also applied for slashing of seats in certain subjects as they have found vacant seats in some subjects. “Colleges are participating in the National Institute Ranking Framework (NIRF) and other assessments by agencies like NAAC. So if these agencies find that sanctioned seats in a certain college is not getting filled up then its image will not be portrayed in a good light. We feel that the institutions applying for decrease of seats have realised the hard reality and have acted accordingly,” a member of CU syndicate said. Also Read – Lightning kills 8, injures 16 in state”Registration and admission in all colleges under CU will be online. Students need not be present physically in any college before commencement of classes,” said Dipak Kar, Pro vice-chancellor (academics) of CU. The admission forms will be made available online in a few days after the publication of Higher Secondary examination results on May 27. Colleges will have to submit their respective merit list by June 10. The admission process will start from June 12 and will continue till July 6. The classes will begin from the first week of July. “We have collected all admission related data from colleges about their seats in pass subjects to have a clear idea of the number of seats and the intake of students,” a syndicate member said.last_img read more

Wasnt it an attempt to score brownie points

first_imgKolkata: The Trinamool Congress on Saturday hit back at outgoing Governor K N Tripathi for his comment that Chief Minister Mamata Banerjee’s appeasement policy had adversely affected the social harmony of the state.Trinamool Congress secretary general Partha Chatterjee wondered why Tripathi did not say this earlier. Next Governor Jagdeep Dhankar will take oath on July 30. “Wasn’t it an attempt to score brownie points? That’s why we (TMC) had said before that the Raj Bhavan has turned into a BJP party office. This has now been proved to be true,” Chatterjee said in a sharp comment. Tripathi had differences of opinion with Banerjee on several occasions regarding various issues during his five-year tenure in the Raj Bhavan. Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: MamataChatterjee, who is also the state Education and Parliamentary Affairs minister, said: “I don’t think that the TMC government’s relation with the outgoing Governor during his tenure was adverse. Any way this observation by him won’t glorify the chair of the Governor.” Tripathi, who has had several run-ins with the Chief Minister, said Banerjee has the vision and power to implement her decisions but needs to keep a check on her sentiments and exercise restraint.last_img read more

Genes may play role in tooth decay gum disease

first_imgHereditary traits and factors such as obesity, education and personality may play a role in tooth decay and gum disease, according to a study. Tooth decay and periodontitis, also known as gum disease, are among the most common diseases around the world but unlike many other well-known diseases knowledge of how genes affect the risk of developing these dental diseases is still limited, said researchers at the University of Bristol in the UK. Two people who eat the same things and take care of their mouth the same way may end up with a different number of cavities but researchers have not been able to explain why until now, they said. Also Read – Add new books to your shelf”The study makes it clear that teeth are part of the body. Among other things, we can see that there seems to be a causal link between risk factors for cardiovascular disease and tooth decay,” said Ingegerd Johansson, from the Institute of Odontology at Umea University, Sweden. Previous research has suggested several genes may be involved but none had been confirmed. This is partly because complex diseases, such as tooth decay and periodontitis, require large studies to draw firm conclusions. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe study, published in the journal Nature Communications, combined data from nine international clinical studies with 62,000 participants together with data on self-reported dental health from the UK Biobank including 461,000 participants, making it the largest study of its kind. The analysis involved scanning millions of strategic points in the genome to find genes with links to dental diseases. The researchers were able to identify 47 new genes with connections to tooth decay. The study also confirmed a previously known immune-related gene is linked to periodontitis. Among the genes that could be linked to tooth decay are those that help form teeth and the jawbone, those with protective functions in saliva and those which affect the bacteria found on the teeth. The researchers also looked at the genetic link to cardiovascular and metabolic health factors such as smoking, obesity, education and personality to try and understand connections with dental health. Using a technique called Mendelian randomisation, it appears there may be more than correlation but also a causal link between decay and some cardiovascular-metabolic risk factors. “In the future, studies like this may pave the way to identifying people who are at particular risk of dental problems,” said Simon Haworth, from Bristol Population Health Science Institute. “However, no matter what genes people carry, good oral hygiene and diet are the most important things people can do to reduce the risk of tooth decay and gum disease,” Haworth said.last_img read more
