Crowd dynamics in the spotlight after Duisburg disaster

first_img © 2010 PhysOrg.com Researcher models effects of suicide bombing: results of crowd configurations (PhysOrg.com) — The Love Parade in Duisburg in western Germany on 24th July was supposed to be a night of music and celebration for the estimated 1.4 million revelers, but it became a catastrophe, with 21 dead and over 300 injured in a stampede as they tried to escape from a crowd disturbance in the only exit/entrance tunnel for the site. Explore further A physicist at Cologne University, Andreas Schadschneider, who specializes in modeling crowd behavior, said after the Duisburg incident that in the majority of crowd disasters panic plays almost no part in the events, and in fact most people act co-operatively and altruistically even under extreme conditions. Schadschneider’s research focuses on pedestrian dynamics at sports stadiums, and he is developing computer software called the Hermes Evacuation Assistant to provide information on the distribution of people, availability of evacuation routes, and the likely route people might use to try to escape during an emergency. His work on Hermes was featured in a Physics World article earlier this month.

Citation: Crowd dynamics in the spotlight after Duisburg disaster (2010, July 29) retrieved 18 August 2019 from https://phys.org/news/2010-07-crowd-dynamics-spotlight-duisburg-disaster.html This experiment shows how walkers self-organize into lanes to avoid interactions with oncoming pedestrians. This helps them to move faster than is otherwise possible. This is part of a project to develop an “evacuation assistant” that could make the evacuation of large buildings safer. While it is not yet certain exactly what happened at Duisburg, Schadschneider said from the footage it seemed the loudness of the music could have been a factor, since it would have been hard for people to hear police commands. He suggested one measure that could be adopted in future large crowd events would be to install more cameras to allow disturbances to be detected earlier, but said it could still be difficult for stewards or police to intercept and change the flow of people. Schadschneider said he hoped the disaster would result in more consultation of crowd dynamics researchers from organizers responsible for crowd management, and that decisions about large crowd events would be overseen by a central governing body rather than being left in the hands of local authorities. The population of Duisburg is under 500,000 people – around one third the estimated number of festival goers on July 24th. While there may have been local planning failures, Schadschneider also said Germany was among the leading countries in the world for crowd dynamics research and applications.

Artificial light found to negatively impact wallabies

first_img © 2015 Phys.org Citation: Artificial light found to negatively impact wallabies (2015, September 30) retrieved 18 August 2019 from https://phys.org/news/2015-09-artificial-negatively-impact-wallabies.html Scientists have been aware for some time that artificial lighting has an impact on wildlife, some of it negative—migrating birds, for example, have been found to go off course due to light from below. Other studies have been conducted, the researchers with this new effort report, but not many have been done in the wild to ascertain an overall impact on a species. To learn more, they ventured off the South-Western coast of Australia, near Perth, to Garden Island—two populations of wallaby live there, one to the north where conditions are more wild, with little to no artificial light, and one in the south, where there is a very large, well lit naval base.The researchers captured five female wallabies from each group and fitted them each with collars that had light sensors, GPS coordinate monitors and a radio to broadcast data to the team. They also captured an additional 70 females and took blood samples. Because the study was mainly focused on the association between exposure to artificial light at night and reproduction schedules, the team also monitored the births of 300 baby wallabies born on the island—all over a five year period.In studying the data, the researchers discovered that the females that lived near the base had much less melatonin in their blood, a hormone that helps to regulate sleep cycles. It also plays a role in raising or lowering the level of progesterone, which in turn has an impact on when a baby is born. The team found that babies born to the wallabies near the base came a month later than for those living in the wild.The timing of births for wallabies is critical, the researchers note, because it needs to happen during the time of year when the mother has the right food in the right amounts to properly nurse her young. In the case of the babies born on the naval base, that was not a problem because the wallabies ate the grass that grew on the lawns there, but babies in the wild, the team suspects, would find themselves cast away if the mother did not have enough to eat to support them. More information: Artificial light at night desynchronizes strictly seasonal reproduction in a wild mammal, Proceedings of the Royal Society B, Published 30 September 2015. DOI: 10.1098/rspb.2015.1745AbstractChange in day length is an important cue for reproductive activation in seasonally breeding animals to ensure that the timing of greatest maternal investment (e.g. lactation in mammals) coincides with favourable environmental conditions (e.g. peak productivity). However, artificial light at night has the potential to interfere with the perception of such natural cues. Following a 5-year study on two populations of wild marsupial mammals exposed to different night-time levels of anthropogenic light, we show that light pollution in urban environments masks seasonal changes in ambient light cues, suppressing melatonin levels and delaying births in the tammar wallaby. These results highlight a previously unappreciated relationship linking artificial light at night with induced changes in mammalian reproductive physiology, and the potential for larger-scale impacts at the population level. Captive-bred wallabies may carry antibiotic resistant bacteria into wild populations (Phys.org)—A team of researchers from Australia and Germany has found that at least one species of mammal is negatively impacted by artificial lighting. In their paper published in Proceedings of the Royal Society B, the team describes a field study they conducted on an island off the coast of Australia and what they found by doing so.center_img Wallaby, photo by Mehgan Murphy, Smithsonian’s National Zoo.

All about edgy metal

Heavy Metal work seemed to be the inspiration behind Anaikka for Kanika Saluja Choudhry. Merging the feminine with the edgy, Kanika played bold with colour and embellishments. Colours like red, gold, millitary green dominated the collection and metal bling was everywhere. If the idea was to essentially show the alpha woman – Anaikka hits the mark. Choudhry works with sheers and flowy crepes without making the collection look overtly feminine. The metal accessories add the perfect edge. Her final ensemble is a punk rock meets metal new age look that had a whole short body suit of sorts in metal topped off with a metal mohawk. We appprove!

Sukumar Ray in english

English translations of 25 Bengali classic short stories penned by one of the most famous Indian writers of literary ‘nonsense’ and humour, Sukumar Ray, were launched on Thursday on the occasion of the literary genius’s 125th birth anniversary. Sukumar Ray, known for collection of poems like Abol Tabol (Gibberish) and Ha-Ja-Ba-Ra-La (Mumbo-Jumbo), was the father of the legendary director Satyajit Ray. Often compared with English author Lewis Carroll, Ray’s imaginative works punctuated with puns and ending with twists charmed children and adults alike with their delightful word play. The translated stories, featuring Ray’s mischievous character ‘Pagla Dashu’ have been put together in the book The Crazy Tales of Pagla Dashu and Co by Hachette India. The stories were translated by the Jadavpur University Translators’ Collective over a period of two years and involved 17 translators. read more

Picking the bones

first_imgIt is not everyday that the city of Tandoori chicken lovers gets to relish fish delicacies. So fish-lover me was actually quite happy to head to The Great Indian Fish Discovery — the latest promotion at Le Meridien’s Eau de Monsoon. There couldn’t really be a better setting for the promotion though. The flowing water around you as you sit down calms you and makes the experience even more pleasant.The variety of fish on offer is mindboggling. And all of these are fresh water fishes. While some of them are traditional recipes from various parts of India, some innovations (like Machhali Mussallam, check recipe) have been made by Davinder Kumar Vice President F&B. There are fish dishes from every part of India though the East (traditionally fish eating) is a little under represented with only the Bengali Macher jhol. Also Read – ‘Playing Jojo was emotionally exhausting’So you have the Goan fish curry and the Pomfret Xacuti; Amritsari macchi (surmai) and Haaq Gadh (singhara) represents north India while Mangalorean fish curry, Meen Moile (pomfret) and Machhali Ka Salan (red snapper) keep south India’s flag flying high. All in all, there are 10 dishes which one can have with either rice or roti. I would recommend pairing the dishes with rice so as to enjoy the gravies.  The Machhali Mussallam is particularly interesting because it is made with trout which has a filling of sole. The Mangalorean fish curry is spicy and delicious and the Patrani macchi (sea bass) is well cooked too. I was a little disappointed with the Macher Jhol though since it was very plain and could have been bettered by using different spices. But do check out the festival.  DETAILAt: Eau De Monsoon, Le Meridien, Windsor Place, Janpath On Till: 18 November Timings: Lunch & Dinner Cost: Rs 1,295 + Taxes Call: 23710101 Novemberlast_img read more

Growing life on canvas

first_imgJungle Me – Green Grafitti, an exhibition of an unusual method of painting on the canvas by French artist Jonathan Longuet  certainly reflects the artist’s enormous creativity. Jungle Me consists of nine  works and seven are in collaboration with Manou, an acclaimed Indian street fashion photographer.Jonathan Longuet works with a ‘living plant paint’, a curious paint solution made from the extraction of algae (a type of organism that grows on damp stones). The artist harvests the algae at the feet of buildings and after cultivating the algae he applies them artistically to a wall or canvas. He calls his algae paintings Green Graffiti which are like a plant growing slowly over time depending on conservation’s conditions. Green Graffiti paint comes from personal researches and cooperation with several biologists and lichenologists since 2005. Also Read – ‘Playing Jojo was emotionally exhausting’Longuet lives and works in Bordeaux, France. For this series, he questioned the notion of the urban jungle- the density, movement with a focus on the people  evolving  in  such  an environment, their relationship with that world which defines their identity. Explaining the concept behind Green Graffiti, Longuet said, ‘A simple microscopic observation of green graffiti allows us to see the territorial wars, food, duplication, waste management, these same problematic issues that we find in the heart of our contemporary  civilizations apply to complex systems of plants. By giving humans  forms to plants, I try to open a dialogue between human beings and their biological environments, highlighting their common traits, their reactions to the reality of survival,their necessity to live in a community.’ Also Read – Leslie doing new comedy special with NetflixThe curator of the exhibition, Elizabeth Rogers comented on Longuet’s style of work and said, ‘Inherent in the Green Graffiti/Jungle Me works of the French artist Jonathan Longuet is a personal exploration of an organic growth process and the unfolding of the natural environment with its increasingly complicated and tenuous relationships with humanity.In essence, they investigate and express energy, effort and inner processes, which extend beyond the archetypical boundaries of aesthetic manifestation to juxtapose and ponder the parallels of science and art.’last_img read more

Engineering humour not designs

first_imgAn engineer doing comedy? Sounds revolutionary but certainly not comic. Bringing in both the characteristics is this engineer turned stand up comedian who will have you in splits with his witty humour and overtly clean jokes (claimed by him) in his show.Appurv Gupta conceptualised the show Appurview- Laugh with an Engineer in Hinglish after he graduated in an engineering degree but realised that his ultimate love and passion lied in comedy. He finally bid goodbye to the profession and since then have been riding high on creating amusement. Also Read – ‘Playing Jojo was emotionally exhausting’This weekend Appurv is back with his show to present different point of view to discuss about the mundane activities in day-to-day life from the point of view of an engineer. The jokes range from why do you see more colleges on road, why everybody wants to do engineering and MBA and then join TCS, Infosys only.  He will further crack and explore our obsession to go to Amereeka, to learn foreign languages and photography, smoking, our posessiveness about mobile phones, algorithm of marriages, Ramayana, Mahabharata, festivals and many more short stories revolving a typical Indian.There is also an opening act by Sumit Anand an engineer and an MBA who tries hard to speak about modern marriage rules, nation’s lust for an MBA and supreme lack of life in the digital life. Come witness the world go laughing while picking up at every engineer.last_img read more

Painting own perspectives

first_imgThrough the works, that derive their inspirations from north Indian history, Dutt establishes an ensemble of images that one could read out as a contemporary artist’s walk through the alleys of history.The works show how intense and relaxed his journeys are through these lanes of history. While looking at the works of the artist, a viewer is not burdened by the facts and figures, on the contrary he/she gets the feeling of getting submerged in time that moves from past to the present and from there to a quiescence.  Also Read – ‘Playing Jojo was emotionally exhausting’Dutt says that the idea behind his works comes all from a rupture in our history. His interest in Mughal Period and its opulence comes from his non-judgmental character. In his works, even when he uses the images of Mughal kings, their thrones, jewels, their harems, Dutt does not try to put something or someone in defense. Especially, when he paints and creates the assemblages through a variety of mediums, his idea is not to make it ‘politically correct’ so that he could always stand on the right side of history. He uses a variety of techniques and styles of representation in this present body of works. He uses comic book space divisions, juxtaposing various layers of images as seen in the contemporary advertisements, the image and literature sources made possible by internet search and above all, the physical evolution of Delhi as modern city, in order fuel the dynamics of his works. Also Read – Leslie doing new comedy special with NetflixHe belongs to a contemporary world but he does not view history as an irreparable dent or a deep hurt. Dutt’s works speak of a museum of innocence, an innocence that had been challenged gravely at some point of time. He takes out events and turns them into vignettes, carefully encased only to be viewed in silence. They are not to be fought over or claimed, but are to be gazed. That’s how a flaneur turns his living city into a contemporary museum of his own reflected existence.When: 3 – 8 SeptemberTiming: 10:30am – 6:30pm Where: Gallery Ragini, Matighar, IGNCA, Man Singh Roadlast_img read more
