Image credit: Léon Woldering, et al. As the scientists explain in their study, most nanotechnologies involve spherical nanoparticles, so different shapes—such as the beads—could offer new avenues of technology with their structural flexibility. In the case of photonic crystals, for example, a single modified colloidal particle inside the photonic crystal could act as an optical cavity to control light.“Our motivation with these nanoparticles is the fabrication of an optical cavity in a three-dimensional photonic crystal by adding additional opal layers to the structures we fabricated, and subsequent inversion of the crystal,” said Woldering. “The inverse opal will be a silicon or titanium dioxide structure. “In order to study the confinement of light, we plan to probe the emission from quantum dots placed near or inside the optical cavity,” he continued. “Alternatively, if the crystal surrounding a cavity in which light is confined is switched by modifying the refractive index, we may be able to release the confined photon at will. This will allow the fabrication of a photon-on-demand light source. A cavity could also act as a highly sensitive on-chip sensor of tiny amounts of matter in, e.g., chemical, biological, or even life-science issues.”Still other applications, as Woldering et al. explain, could emerge in the development of solar cells with highly efficient light transmitters. Also, these opals could provide a resource for plasmonics devices, such as computer chips, and even optical microscopes that can focus on objects smaller than a wavelength of light.Citation: Woldering, Léon A., Otter, A.M. (Bert), Husken, Bart H., and Vos, Willem L. “Focused ion beam milling of nanocavities in single colloidal particles and self-assembled opals.” Nanotechnology 17 (2006) 5717-5721.By Lisa Zyga, Copyright 2006 PhysOrg.com One of the most rapidly advancing areas of applied nanotechnology involves photonic crystals. With their ability to control light propagation, photonic crystals are predicted to replace other methods for devices such as display lasers, circuits and quantum computers. Although complex manufacturing has stunted their fabrication, scientists have recently found a new technique to control the size, shape and chemical flexibility of opals, a type of photonic crystal, to the smallest degree yet. Explore further “The essence of our work is that we are able to control the shape of individually addressed nanoparticles inside artificial opals,” Léon Woldering, coauthor of the study, told PhysOrg.com. “We fabricate nanocavities in individual colloidal particles, and can change the position of these cavities and tune the diameter with nanometer precision. We thus realize a kind of nano-donut, or nano-bead.”Woldering, and the rest of his group from the Netherlands, used a technique called focused ion beam milling (FIB) to “drill” (or “mill”) 80-nm-wide cavities into single colloids on artificial opals. The individual colloids, about 100 nm in radius, were grown through a self-assembly technique from silicon dioxide colloidal spheres. In their investigation, the scientists milled cavities for a duration between five and 30 seconds, and found that longer milling times corresponded to larger cavities. “Not only is the nanotechnology to make these cavities extremely interesting in itself, but also the method we developed to mill these structures on a non-conducting substrate is novel and expands the possibilities of FIB in general,” said Woldering.Usually, the FIB technique does not have a reputation for precise high resolution applications such as the fabrication of the nanobeads here. In the past, techniques using electron beams and laser beams could create large modifications in opal films, but not with this great detail. Although Woldering et al. encountered challenges due to the small, non-conductive opals made of easily loosened elements, they still succeeded in creating much smaller modifications than previous techniques.“FIB on an insulating substrate is a challenge in general,” explained Woldering. “In our case, even more so, because milling on our substrates causes the individual colloidal spheres to charge, after which they repel each other and are ejected, thereby destroying the crystal. We were able to promote the diffusion of charges away from the milled area by deposition of a conducting carbon layer on top of the substrate, and by adapting an intermittent milling procedure. In this fashion, the breakdown of the photonic crystal was prevented, and we were able to obtain our nanocavities.” This document is subject to copyright.

The multi-touch steering wheel hardware. Image: Tanja Döring et al. © 2010 PhysOrg.com Lane departure warning systems help drowsy drivers avoid crashes With the numerous technological advances such as mobile phones and texting, the need to keep drivers focused on the road is the idea behind the development of this touch-screen steering wheel. With standard vehicle controls being behind the steering wheel or in the center console, making changes requires the driver to look away from the road. Albrecht Schmidt, a computer science professor who worked on the project believes by creating gesture-enabled steering wheel, drivers will be able to spend more time focused on the road.The steering wheel is made out of 11 millimeter thick acrylic that is ringed with infrared LEDs. There is an infrared camera that is attached to the bottom that detects reflections when the screen is touched. Gestures can be made on the screen without the driver ever having to take their hands off the steering wheel.To create the prototype, researchers asked participants what movements and gestures they currently used on technological devices in order to create the gestures for some 20 commands. Gestures such as pinching two fingers in order to zoom or tracing out the first letter of a command are some that have been included.Once they had established all the different general commands and gestures, the researchers then had participants test the steering wheel in a simulator. The data from the study shows that the new prototype was able to substantially reduce the amount of time a driver needed to take his eyes off the road.Down the road, they believe the technology could include things such as the ability to project information directly onto the windshield as well as a sensor system designed to check road conditions and traffic and alert a driver to stay focused on the road.The prototype was presented at the Conference on Human Factors in Computing Systems and the researchers are currently speaking with automotive companies to look at the possibility of getting this technology into vehicles in the near future.

More information: Broad range of 2050 warming from an observationally constrained large climate model ensemble, Nature Geoscience (2012) doi:10.1038/ngeo1430AbstractIncomplete understanding of three aspects of the climate system—equilibrium climate sensitivity, rate of ocean heat uptake and historical aerosol forcing—and the physical processes underlying them lead to uncertainties in our assessment of the global-mean temperature evolution in the twenty-first century1, 2. Explorations of these uncertainties have so far relied on scaling approaches3, 4, large ensembles of simplified climate models1, 2, or small ensembles of complex coupled atmosphere–ocean general circulation models5, 6 which under-represent uncertainties in key climate system properties derived from independent sources7, 8, 9. Here we present results from a multi-thousand-member perturbed-physics ensemble of transient coupled atmosphere–ocean general circulation model simulations. We find that model versions that reproduce observed surface temperature changes over the past 50 years show global-mean temperature increases of 1.4–3 K by 2050, relative to 1961–1990, under a mid-range forcing scenario. This range of warming is broadly consistent with the expert assessment provided by the Intergovernmental Panel on Climate Change Fourth Assessment Report10, but extends towards larger warming than observed in ensembles-of-opportunity5 typically used for climate impact assessments. From our simulations, we conclude that warming by the middle of the twenty-first century that is stronger than earlier estimates is consistent with recent observed temperature changes and a mid-range ‘no mitigation’ scenario for greenhouse-gas emissions. (PhysOrg.com) — Over the past several years, researchers have built a variety of computer simulations created to predict Earth’s climate in the future. Most recently, most models have suggested that over the next fifty years, we’ll see an average worldwide rise in temperature of perhaps 1°C. Now a new group of simulations, using the combined computing power of thousands of personal computers, says that number is too low, and that we might see temperatures rise as much as 3°C, which would of course, be a far more serious situation. The simulations, run by climateprediction.net in conjunction with the BBC Climate Change Experiment, resulted in predictions of a rise in temperature ranging from 1.4°C to 3.0°C by 2050. The large team involved in the project has published their findings in Nature Geoscience. Warming of two degrees inevitable over Canada: study Explore further Journal information: Nature Climate Change © 2012 PhysOrg.com , Nature Geoscience While very few if any climate scientists expect a rise of 3°C would destroy our way of life, such a change would almost certainly result in much higher ocean levels, permanently flooding many coastal areas. Many also see a rise of 2°C, as the tipping point, or point of no return, which could some time in the distant future spell doom for our species if not our planet. Many suggest that such a rise could also have a profound impact on weather systems. One recent study by a team of researchers and published in Nature Climate Change, reports on findings that suggest recent weather patterns are already showing signs of change due to global warming. A higher incidence of tornadoes in the US, a heat wave in Russian, flooding in Pakistan, etc. are all linked to elevated temperatures.The new computer simulation model was a modification of one already used by the UK’s meteorological agency to predict global temperature changes. It was modified to more accurately take into account carbon emissions, how fast oceans absorb heat, and heat reflected back into space by aerosols in the atmosphere. The simulation was then run over 10,000 times on personal computers offered for service by home computer users, each with slightly different parameters and each covering the period 1920 to 2080. Every simulation also ran with the assumption that carbon emissions would continue to be spewed into the atmosphere at the same rate as occurs today. Once data was received from all the simulations, the researchers discarded those findings that didn’t make sense in a contextual sense. Of those remaining, none showed an increase of less than 1°C over temperatures from just a decade ago, while nearly 15% of them showed a rise of as much as 3°C by the year 2050.While this new simulation isn’t definitive proof that temperatures worldwide will increase as much as predicted over the next thirty eight years, it most definitely is a warning that we as a species would be putting ourselves in peril if we don’t find a way to stop pumping carbon emissions into the atmosphere sooner rather than later.

Test pilot Yates is now the first person to ever fly an electric aircraft faster than 200 miles per hour, in his test flight last week at the Inyokern Airport in California’s Mojave Desert. The plane that he flew is called the Long-ESA, (for Electric Speed and Altitude). The aircraft is a modified Long-EZ, serving as a development platform for a new electric aircraft system which will be utilized for a flight across the Atlantic later on. The transatlantic flight is scheduled for 2014. Explore further (Phys.org) — Last week’s record of the fastest ever manned electric aircraft was set by electric-vehicle record-setter Chip Yates. He already had credentials as holding the world record for fastest electric motorcycle going over 196 mph last year. As a test pilot this time around, Yates flew an electric airplane and achieved 202.6 mph in level flight. This topped the previous record of 175 mph last year by the electric aircraft Cri-Cri. The latter, flown by French pilot Hugues Duval, broke the record during the Paris Air Show. The aircraft was powered by a pair of 35-horsepower electric motors and a pair of lithium polymer batteries. World’s first aircraft with serial hybrid electric drive The electric Long-ESA, powered by a 258 horsepower electric motor, is being worked on by electric aerospace company Flight of the Century (FOTC), where Yates is CEO, as an R&D plane for development of the company’s “mid-air recharging technology.” The company team converted Burt Rutan’s Long-EZ airplane (Rutan is an aerospace engineer) for the trial flight. In a two-month workup at the FOTC site, the plane’s gasoline power was converted over to electric power. Just how much can an electric plane achieve? So far, engineers looking at the electric plane’s future in practical terms are concerned the most with range rather than speed, and news of speed records command less attention than longevity of flight. In recognition, Yates hopes his speed runs will help develop the technology needed for longer-endurance flights and more practical electric aircraft. Yesterday’s flight of the electric Long-ESA lasted only 16 minutes. There was a hitch when Yates realized that a battery had been run too low and he had to land sooner than expected. Long-ESA will be given a more capable battery pack as part of subsequent work. The company expects a top speed of 230 to 250 mph with the full-size battery pack in place in September.Yates, meanwhile, is bringing the Long-ESA to the 2012 EAA AirVenture Oshkosh event, which runs July 23 to July 29, where the craft will go on display and where he will present his flight data. FOTC engineers worked on the test program to generate data, video and knowledge in time to share with attendees. After Oshkosh, the company intends to equip the Long-ESA with a custom designed lithium-ion series of battery packs and a front-mounted recharging probe to test mid-air tethering and battery jettison along with “rebalance” technologies. Beyond this test flight, the core mission behind FOTC is to extend the range and endurance of an electric-powered aircraft by replacing battery packs in flight using its mid-air refueling technique of “flying battery packs,” drones full of batteries, for various ground or ocean stations. A UAV would detach from the “mothership” once the batteries are depleted and fly down to a recharging station as a freshly charged battery pack is launched to dock with the aircraft. © 2012 Phys.org Citation: Record-setting electric airplane exceeds 200-mph (w/ Video) (2012, July 23) retrieved 18 August 2019 from https://phys.org/news/2012-07-record-setting-electric-airplane-mph-video.html More information: www.flightofthecentury.com/
© 2014 Phys.org Journal information: Science (Phys.org) —A team of researchers working in Spain has developed an improved way to control surface plasmon polaritons (SPPs) in graphene. In their paper published in the journal Science, the team describes their new technique and the ways it might someday be used. Explore further Research group devises a way to control surface plasmon polaritons Credit: University of Manchester Citation: Physics team develops simple way of controlling surface plasmon polaritons in graphene (2014, May 23) retrieved 18 August 2019 from https://phys.org/news/2014-05-physics-team-simple-surface-plasmon.html A plasmon is defined as a quantum of plasma oscillation and is generally considered to be a quasiparticle. Polaritons are quasiparticles that arise when plasmons couple with photons—and as their name implies SPPs are polaritons that exist on the surface of a material and propagate into it. Researchers at several facilities are currently studying the properties of SPPs in an effort to create extremely tiny devices that operate both optically and electronically. In order to make that happen, a means must be developed of controlling the size and shape of SPPs—that’s what the team in Spain has achieved.SPPs can be made to occur in metals, but prior research has shown that graphene is a better material because SPPs can propagate deeper into it. Two years ago, the same research team in Spain (working with others) developed a way to create and image SPPs in graphene using a near-field scanning optical microscope. With this latest effort, they’ve taken that work further with the development of a method that allows for actually controlling the SPPs. To make it happen, they covered a sheet of graphene with extremely tiny (3 μm) antennas made of gold—the antennas absorb photons at a given frequency. Doing so created an optical dipole which caused the creation of evanescent light. Because the antenna was directly connected to the graphene, SPPs were created from the near field—changing the antenna size allowed for altering the SPPs that were created. The team found that a straight antenna caused the creation of planar SPP waves. When the antenna had a concave tip, the SPP waves were focused to a single point. The team also found that the SPP waves could be refracted using a two-dimensional bilayer graphene prism.More research must be done with SPPs before they can be used to create opto/electronic devices, however, because the distance they propogate into the graphene (just 1–2 μm ) is still too small to be of practical use. The team hopes to increase that distance by using better quality graphene and by developing a better doping process.

Here,we introduce a versatile platform technology based on resonant optical antennas and conductivity patterns for launching and controlling of propagating graphene plasmons, constituting an essential step for the development of graphene plasmonic circuits. We demonstrate the launching and focusing of infrared graphene plasmons with geometrically tailored antennas, and how they refract when passing through a 2-dimensional conductivity pattern, here a prism-shaped bilayer. To that end, we directly map the graphene plasmon wavefronts using an imaging method that will also benefit the testing of future design concepts for nanoscale graphene plasmonic circuits and devices.Press release This document is subject to copyright.

More information: Nicolas Nagloo et al. Spatial resolving power and spectral sensitivity of the saltwater crocodile,, and the freshwater crocodile,, The Journal of Experimental Biology (2016). DOI: 10.1242/jeb.135673ABSTRACTCrocodilians are apex amphibious predators that occupy a range of tropical habitats. In this study, we examined whether their semi-aquatic lifestyle and ambush hunting mode are reflected in specific adaptations in the peripheral visual system. Design-based stereology and microspectrophotometry were used to assess spatial resolving power and spectral sensitivity of saltwater (Crocodylus porosus) and freshwater crocodiles (Crocodylus johnstoni). Both species possess a foveal streak that spans the naso-temporal axis and mediates high spatial acuity across the central visual field. The saltwater crocodile and freshwater crocodile have a peak spatial resolving power of 8.8 and 8.0 cycles deg−1, respectively. Measurement of the outer segment dimensions and spectral absorbance revealed five distinct photoreceptor types consisting of three single cones, one twin cone and a rod. The three single cones (saltwater/freshwater crocodile) are violet (424/426 nm λmax), green (502/510 nm λmax) and red (546/554 nm λmax) sensitive, indicating the potential for trichromatic colour vision. The visual pigments of both members of the twin cones have the same λmax as the red-sensitive single cone and the rod has a λmax at 503/510 nm (saltwater/freshwater). The λmax values of all types of visual pigment occur at longer wavelengths in the freshwater crocodile compared with the saltwater crocodile. Given that there is a greater abundance of long wavelength light in freshwater compared with a saltwater environment, the photoreceptors would be more effective at detecting light in their respective habitats. This suggests that the visual systems of both species are adapted to the photic conditions of their respective ecological niche. New look at crocodile eyes Most people have seen, if only on video, the silent means by which crocodiles hunt—with their bodies just below the surface and only their eyes and part of their snout visible—they wait for prey to wander close enough to grab with their long tooth filled maws. Now, in this new effort, the researchers have found a feature of their eyes that assists them in this type of hunting; the fovea, which is an area of receptors in the back of the eyeball that are set very close to one another, and in the case of crocodiles, they are formed as a long streak, rather than as a circular spot seen in other animals. It allows, the team explains, the animal to scan the near horizon without having to move its head at all—that makes it easier to sneak up on unsuspecting animals.The researchers report that they also found a major difference between the eyes of the saltwater crocs, versus their freshwater counterparts—the numbers of different types of photoreceptors in the retina. Freshies, as they are called, had more that were responsive to red light, whereas salties had more that were responsive to blue light. This, the team reports, makes sense because saltwater tends to have more blue light in it, while freshwater has more red in it. But, that is only a partial explanation, the team adds, because but both types of crocs have blurry vision when underwater. This, they suggest, means that the crocs do something under water that is still unknown, which is odd, because they do most of their hunting and mating on land. Both types do have the stretched fovea, they note, allowing them to lurk beneath the water without having to lift their heads, making their presence easier to mask—a feature, they report, that has not been seen in any other animal.

‘Plan your work and work your plan,’ suggests Michel Koopman, General Manager at The Leela Kempinski Gurgaon, as he settles in with a glass of Perrier for the ‘grueling’ interview with Millennium Post. A month (and a little more) into being at the helm of affairs for the hotel, Koopman has big plans and perhaps the best part of it is that he is brilliantly methodical when it comes to executing them (trust us, he had a PPT!). Despite a traditional educational base of Greek and Latin, Koopman had no plans of becoming a doctor or a lawyer he says. Since he was too young to join the hotel school at The Hague ( Higher Hotelschool for Hotel management) – he was only 20 then – he had to wait it out. So the journey that finally began with Assistant Chief Steward at the Amsterdam Hilton, has traveled far and wide and found base in India, for now. Also Read – ‘Playing Jojo was emotionally exhausting’ And we say for now because by the looks of it, Koopman loves to travel, there isn’t a place in the world he hasn’t been to it seems. When we asked him about it and he started listing the places he has seen, we had to stop him and asked him for places he had not seen instead. Amsterdam, Jakarta, Bali, Osaka, Perth, Canberra, Melbourne, Pudong, Shanghai and the list goes on. ‘My first visit to India was when I had a ponytail,’ laughs Koopman, that was years ago and perhaps then, he had no idea that life would come full circle. Also Read – Leslie doing new comedy special with Netflix Speaking about his past experiences, Koopman says that he learnt to hone his analytical thinking in schools but the more real, on-hand training came from all the work he did on the side while he was still a student. From scratch in the hotel business to managing a team of workers under him, Koopman picked the tricks of his trade working it out for himself. ‘You have to take two steps backwards to take a huge step forward at times, it is the catapult effect,’ says Koopman explaining that there were times when he took a designation cut in his career to make sure he learned the right things. ‘It is essential to get your core values right,’ says he and goes on to say that this is the exact philosophy he has planned for Leela Kempinski. Everyone in the staff should know what exactly is expected of him or her and then develop skills along those lines. At this point Koopman shares a delightful anecdote on the man who swept the floors at Cape Canaveral. When asked about what he does – the man had replied – ‘I make sure that men can walk on the moon’ Confused much? So were we till Koopman explained that according to this man, if he did not do his job right at the lowest rung of the NASA operations, something would go wrong up the ladder right till the Apollo 11 launch. ‘The idea is to develop, empower, engage and reward people and everyone should know what is expected from them- that is the Dharma Chakra,’ says Koopman. The Leela caters to making guests feel like king, guests like their privacy and space and we should respect that, he adds. So what are the big plans for Leela Kempinski? ‘I want to focus on the strengths of the hotel, fine tune those and make sure we follow our Vision – To be recognised as the leading International luxury hotel by our primary target markets, corporate and MICE. The hotel will exceed the expectations of our colleagues, guests, owners and The Leela. Our values are aligned with Athiti Devo Bhava,’ he says. While the restaurants on the property – Spectra and Diya are definitely on Koopman’s list – he wants to bring up the concept of signature dishes in the hotel. ‘Fine dining is passe,’ he says. The man loves his food, his wine and his occasional cigar – so we trust him. ‘The idea is to authenticate. People in India focus on one great dish, which they want it right and will travel a long way to experience it. That is what signature dining is about,’ explains Koopman. While he can’t wait for his twin daughters and wife to join him in India, Koopman keeps himself busy with his sports and books. Nothing to complain about, we say!
So what does this show explore? Well, the answer is a list of questions. What is devotion? Is it a mere a tool? Or a religious observation or worship? Or an instant mantra to quell one’s innermost disquiet? Or is it all a grand delusion and religious posturing? These are some of the ideas that this show explores through the works on display. Bajaj noted, ‘The art works in the show portray multidimensional elucidations of devotion and the way it transmutes individual entities. There are works that conjure up peace and spiritualism while others that invoke disquiet and action.’ Also Read – ‘Playing Jojo was emotionally exhausting’The show opens today with the performances by Sweta Bhattad and leading puppeteer of India Dadi Pudumjee.This exhibition brings in an interesting exercise to examine the modern intellectual’s notion about devotion. The show has been in the making for the past one year and eminent group of artists contributed to make it so beautiful and absorbing.Curator Puri explains, ‘Great literature, art and cinema have always flourished in times of turmoil and strife. If censorship has imposed laws to stop the common man from protesting, art has provided the perfect platform for him/her to express angst through art.’ Also Read – Leslie doing new comedy special with NetflixThe art works by this fairly large and varied collection of artistes, depicts devotion the most basic and profound human emotion since the inception of the civilization, in multidimensional forms and renditions reflective of each individual entity and his/her leanings or preoccupations.The concept for this annual show on this open platform is reflective of the gallery’s own ethos and support to a diverse representation of art where the only limitation is the ideas that the artiste is able to dream up and the degree of their dedication and commitment to realise it.When: On till 15 January 2015 Where: Gallery Art Positive, Lado Sarai Timing: 10.30am – 7.30pm

Men may feel threatened by woman bosses and act more assertively towards them than male supervisors, a research says. The study published in the journal Society for Personality and Social Psychology said that such behaviour by male employees working with woman managers could disrupt the workplace with struggles over power dynamics.“The concept of masculinity is becoming more elusive in society as gender roles blur, with more women taking management positions and becoming the major breadwinners for their families,” said researcher Ekaterina Netchaeva, assistant professor of management and technology at the Bocconi University in Milan.

Kolkata: A mob vandalised a school in New Town area of North 24 Parganas district on Thursday after a video purportedly showing a school teacher in a compromising position with a class 10 girl student went viral on social media, police said.The parents and students of the school in Patharghata area went on a rampage at around 4 pm after the alleged video purportedly showing the teacher and a class 10 girl student in a compromising position went viral on social media network and news of the video spread like wildfire, the police said. “We have not arrested the teacher as we are trying to find out the genuineness of the video. It has been sent for forensic test,” a senior officer of Bidhannagar Police Commissionerate said, adding that a probe has been initiated into the matter. As the mob, joined by outsiders, vandalised school property demanding the accused be immediately arrested, the school authorities called the police and handed over the accused teacher to the police, a school spokesman told reporters. The headmaster of the school said: “We condemn any such act by a teacher who should set example by his conduct before the students and not get involved in any conduct which can be questioned by others. A teacher should boast off good moral character.”He said after the teacher was handed over to police, the situation at school became normal and the school authorities will cooperate with the police. The police said they were also looking for those who were involved in vandalism at the school premises.
Kolkata: In the wake of the recent incident of a devastating fire at Bagree Market, the Kolkata Municipal Corporation (KMC) has decided to take prompt action against the illegal encroachments in front of all the marketplaces including those owned by the civic body.Mayor Sovan Chatterjee who is also in charge of the State Fire and Emergency department on Tuesday said that action will be takenagainst those who are encroaching the pavements in front of the various market complexes in the city.The KMC and fire department officials will conduct surveillance in all the markets to oust the illegal encroachers.”The Fire department had faced great difficulties while dousing the flame inside the Bagree Market due to the encroachment on the pavements. We will not allow anybody to occupy the space in front of the markets. Those who are illegally encroaching the pavements in front of the market areas will be asked to vacate the place failing which, a legal action would be taken against them,” the Mayor said.Earlier in the day, Chatterjee held a meeting with the Member and Mayor-in-Councils in the KMC in this regard. He also added that the illegal encroachments obstructed the fire officials to combat the blaze at Bagree Market.”All the owners of the shops will be instructed not to keep any goods on the pavements adjacent to their shops. Instructions will be issued to those who run shops in the markets restricting them from using the pavements. The civic body and the Fire department may also take steps against the vendors putting their stalls on the pavements,” Chatterjee said. He mentioned that an FIR has been lodged against the CEO and the director of the Bagree Estates Private Limited by the state Fire department for their failure to put in place adequate firefighting mechanisms in the market. The civic body had issued notices to various markets including the Bagree Market to arrange for water reservoirs and sprinklers. But in case of Bagree Market, two reservoirs that were there were empty at the time of the incident, giving a very difficult time to the fire officials.”We are looking into why the reservoirs were empty. As a result, the fire officials had to arrange water from various other places. The firefighters did a commendable job. They restricted the fire from spreading. We are now issuing some fresh notifications to the KMC-owned markets and others to strictly meet all the required parameters set by the civic body and the Fire department,” Chatterjee said.
Your colleagues at work – and not your spouse or kids – decide how healthy you will be as you age, as you are likely to spend an average of one third of your day on the job. According to the researchers, health at work is determined to a large extent by our social relationships in workplace – and, more particularly, the social groups we form there. In a new meta-analysis covering 58 studies and more than 19,000 people across the globe, psychologists found out that how strongly we identify with the people or organisation where we work is associated with better health and lower burnout. “This study is the first large-scale analysis showing that organisational identification is related to better health,” said lead researcher Dr Niklas Steffens from University of Queensland, Brisbane, Australia. Also Read – Add new books to your shelf“The results show that both performance and health are enhanced to the extent that workplaces provide people with a sense of ‘we’ and ‘us’,” Steffens added. The team reviewed 58 studies covering people in a variety of occupations, from service and health to sales and military work, in 15 countries. “Social identification contributes to both psychological and physiological health, but the health benefits are stronger for psychological health,” said Steffens. The positive psychological benefit may stem from the support provided by the work group but also the meaning and purpose that people derive from membership in social groups.

The authors also found that the health benefits of identifying with the workplace are strongest when there are similar levels of identification within a group – that is, when identification is shared.So if you identify strongly with your organisation, then you get more health benefits if everyone else identifies strongly with the organisation too. The team was surprised to find that more the women present in a sample, the weaker the identification-health relationship grew. “This was a finding that we had not predicted and, in the absence of any prior theorising, we can only guess what gives rise to this effect,” said Steffens in a paper appeared in the journal Personality and Social Psychology Review. One of the reasons may relate to the fact that there are still many workplaces that have somewhat “masculine” cultures. This mean that even when female employees identify with their team or organisation, they still feel somewhat more marginal within their team or organisation. The team also recommends exploring the role of leadership: how leaders manage teams and groups has a strong influence on the social identification-health connection.

This will enable customers to weigh things purchased by them and feel convinced that they have not been cheated by the shopkeeper. “As per law, there is punishment for shopkeepers who cheat people by giving them things less than the original weight. Common people often complain that some shopkeepers manipulate their weighing machines to fleece customers. We want to ensure that customers are not cheated by any means,” Pande added. Mayor Firhad Hakim said that the complaint box has been installed to ensure that nobody is cheated under Right to Public Service. “If a consumer feels that a civic body official is unnecessary delaying service to him/her, complaint can be dropped in the box. Action will be taken as per law. Chief Minister Mamata Banerjee wants consumer rights to be upheld in Bengal in the best possible manner,” Hakim said.

Kolkata: Bringing to the fore the failure of production houses in clearing payments in West Bengal’s entertainment industry, an association of suppliers on Monday threatened to go on a cease work agitation if their dues were not cleared in the next four days. “The suppliers are facing huge problems as certain producers haven’t cleared payments (in crores) for a very long time… Till Thursday if we don’t see any initiation of payment, the suppliers will not take the responsibility to support the industry,” Neet Paul, General Secretary, Cine Video and Stage Supplier Welfare Association (CVSSWA), told the media here.

There are 60-70 members in the welfare body and more than 600 people who work under them. Many suppliers have become bankrupt and one of them even thought about committing suicide. “We are no one to stop work but the vendors are helpless and will not be able to provide the supplies without payments. We could have taken a legal step but wanted the channels, producers and suppliers to sit together and solve the issue,” Argha Mitra, Assistant Secretary, CVSSWA, said.

The said producer has allegedly not cleared payments of 14 suppliers for some of his television serials. “We still hope that the industry will support us. We do believe in the judicial system but we cannot wait for months and years involved in a legal process and want the matter to be solved within ourselves,” Paul said. The West Bengal Motion Picture Artists’ Forum is supporting the suppliers. “We are approaching the channels as the serials are their products and they can easily solve the issue by making the payments. If the artists and technicians can get their dues, the suppliers should not be left behind,” Mitra added. Costume supplier Zakir Hossen Mollick, a member of the body, said the producers thought that the suppliers lacked a collective voice and no one will stand up against them.
