Previous research on the teapot effect has found that at higher flow rates the layer of fluid closest to the surface of the teapot spout becomes detached from it and the fluid flows smoothly. At low flow rates there is flow separation in which the boundary layer reattaches to the surface instead of flowing over it, causing the flow to stop and start; in other words to dribble. A number of factors are known to affect how much the teapot dribbles, such as the diameter of the spout, the teapot material, and speed of flow, but until now no one has come up with a scientific solution.Fluid dynamics experts C. Duez, C. Ybert, C. Clanet, and L. Bocquet, from the University of Lyon have solved the problem by identifying the fundamental cause of dribbling: a “hydro-capillary” effect that keeps the liquid in contact with the surface as it leaves the spout. The other factors — “wettability” of the teapot material, velocity of the flow, and curvature of the lip — determine the strength of this effect.The authors suggest that one way to avoid dribbling is to make the lip of the spout as thin as possible (as in metal teapots, which rarely dribble), while the ultimate way to instantly stop dribbling and end the teapot effect for good is to use a thin, sharp-ended spout and coat the lip with one of the latest super-hydrophobic materials. These materials strongly repel water and prevent the tea from clinging to the teapot material, which adds weight to the old idea that smearing butter on the spout stops dribbling.Duez and his colleagues also suggest that some super-hydrophobic materials can be controlled electronically, and while it is hard to see why anyone would want a teapot with a dribble switch, there may be applications in controlling fluid flow in microfluidic devices.The research paper is published online in arXiv.org.More information: Beating the teapot effect, C.

Sony patent seeks to correct autostereoscopic blur

first_img © 2012 Phys.Org Image: USPTO, number 0910660.0 What this means is that Sony is planning to resolve the disadvantages of no-glasses 3-D viewing in the home. Critics have often noted blurring and other compromised effects that make the 3-D viewing experience less than desired just because the viewer is not in the best position. The success of autostereoscopic (glasses-free) 3-D has depended highly on the viewer’s angle and distance from the screen. With Sony’s 3-D viewing concept, the application would be able to detect a user’s distance from the screen and adjust the separation of images accordingly.Sony points out past technology limitations of 3-D viewing with no glasses in its patent: “3-D content is recorded using a stereoscopic camera having a fixed arrangement of lenses that presuppose a corresponding fixed viewing position.” The problem, says Sony, is that the effect of being in the wrong place for viewing is discouraging. According to the patent, “the reproduced image can feel unnatural and in extreme cases may lead to headaches or nausea.” Sony says one particular weakness is under- or over-exaggeration of depth, depending on how near or far the user is from the screen.The patent is for both an image-processing method and an entertainment system for the image display. The patent says that Sony’s technology involves shifting image elements in at least one of the left-eye and right-eye images to change the size of displacements, as a function of existing displacements, and the point of intersection of lines of sight between the corresponding image elements and the viewer. The separation in depth between different image elements is substantially the same as it would have been if the user had been viewing the video at the ideal distance.Sony’s patent does not represent the first attempt of a company seeking to evolve non-glasses 3-D viewing. Cebit in 2010 in Hanover, Germany, is a case in point. Technology companies at Cebit created a stir showing efforts toward a new breed of displays. Sunny Ocean Studios had a panel fitted to a standard display, sending out a stereoscopic image to 64 positions around the screen. That meant you would be able to “run around” and see a nice 3D display, said Armin Grasnick of Sunny Ocean, at the time. Another company, SeeFront, showed a display moving with the viewer’s eyes, with the viewer always seeing the 3-D image. Eye-tracking has been an essential component of its glasses-free 3-D display technology, according to SeeFront.

Climate change may be making bearded dragons less intelligent

In their paper published in the journal Royal Society Open Science, the group describes exposing incubating bearded dragons to warmer than normal air temperatures and then testing their intelligence.

Incubation environment impacts the social cognition of adult lizards, Royal Society Open Science (2017). DOI: 10.1098/rsos.170742AbstractRecent work exploring the relationship between early environmental conditions and cognition has shown that incubation environment can influence both brain anatomy and performance in simple operant tasks in young lizards. It is currently unknown how it impacts other, potentially more sophisticated, cognitive processes. Social-cognitive abilities, such as gaze following and social learning, are thought to be highly adaptive as they provide a short-cut to acquiring new information. Here, we investigated whether egg incubation temperature influenced two aspects of social cognition, gaze following and social learning in adult reptiles (Pogona vitticeps). Incubation temperature did not influence the gaze following ability of the bearded dragons; however, lizards incubated at colder temperatures were quicker at learning a social task and faster at completing that task. These results are the first to show that egg incubation temperature influences the social cognitive abilities of an oviparous reptile species and that it does so differentially depending on the task. Further, the results show that the effect of incubation environment was not ephemeral but lasted long into adulthood. It could thus have potential long-term effects on fitness.Press releasecenter_img Journal information: Royal Society Open Science Central bearded dragon. Credit: Greg Hume/Wikipedia/CC BY-SA 3.0 © 2017 Phys.org Over the past several years, scientists have been finding that creatures great and small are smarter than commonly assumed. This is the case for bearded dragons, the people-friendly reptile from Australia. Some studies have shown, for example, that they are able to note the behavior of their peers and then copy it if it offers a reward. Such behavior offers a means for testing the intelligence of individuals among a group.To find out what impact rising temperatures might have on the bearded dragon, the researchers incubated 13 eggs, seven in a warmer than normal 30 degrees Celsius nest and six at the normal 27 degrees C. After they hatched and grew older, the researchers tested the intelligence of all the lizards by exposing them to a video showing a bearded dragon opening a sliding door and then testing them to see if they could or would imitate the behavior for a reward—prior research showed that opening a screen door is something the lizards can only learn if they see another lizard do it first.The researchers report that fewer of the lizards that incubated in the warmer pens were able to mimic the lizard on the video than those that had incubated at normal temperatures—and those that did succeed did so at a much slower pace. This, the researchers suggest, indicates that as the planet warms, animals across the globe will be impacted in some unexpected ways. For the bearded dragon, it could spell serious trouble if they become less intelligent, making them less able to adapt to change. The researchers also note that their results are similar to those of researcher Jonathan Webb—he found that exposing geckos to warmer temperatures in the nest made them not only duller but less likely to survive once released into the wild.

Carbon climate and North Americas oldest boreal trees

first_imgThe researchers used a dual-isotope analysis of tree rings (δ 13 C and δ 18 O; carbon-13 and oxygen-18, respectively) to track changes in iWUE over a 715-year period. Their results showed “a remarkable and unprecedented (59%) iWUE increase over the past 150 y,” the period tracking the onset of major anthropogenic atmospheric carbon emissions. Examination of dual-isotope data from this period revealed two distinct patterns of iWUE activity, each corresponding to two of the three iWUE scenarios described earlier. The first phase, spanning the years 1850 to 1965, corresponded to S1, where ci remains constant in relation to increasing ca. This time period showed a 28% increase in iWUE compared with the pre-industrial average from the preceding 550-year period. By 1965, when ca levels reached 320 ppm however, iWUE activity shifted to reflect a constant ci/ca ratio (0.49), as described in S2, and this was accompanied by an additional 31% rise in iWUE. The rate of increase in iWUE observed in the first phase of the study is among the highest ever seen in the Northern Hemisphere, and remarkable also in that the response occurred in already mature trees. The shift in activity from a constant ci to a proportional Ci/Ca relationship—a change in paradigm from S1 to S2—that took place in the second period beginning in 1965, was also remarkable. No such shift had previously been observed in a North American boreal forest.The observed shift in the trees’ acclimation strategy suggested physiological changes either in A, gs, or both, and so the researchers looked to clues in the dual-isotope analysis to clarify the mechanism at work in both time periods. They found that in the first period, from 1850 to 1965, A (assimilation rate) stimulation by increased CO2 probably drove iWUE increases; but after 1965, the iWUE response likely changed to one dominated by gs, that is, in this case—declining stomatal conductance. In essence, these trees seemed to employ a strategy that maximized carbon gains at relatively low ca, as seen in period 1. However, beginning in 1965, the trees switched over to a drought-avoidance strategy as their photosynthetic apparatus approached a saturation point, after which water losses would be disproportionately high in comparison to carbon gains, were they to maintain a constant ci.Next, the researchers looked at variations in climate in relation to iWUE, examining variables such as soil moisture index, vapor pressure deficit, and temperature. Their analysis showed that, while each of these climate-related factors did have a significant effect on iWUE between 1953 and 2014, each had a maximal effect at a different time frequency. Moreover, the very large increase in iWUE beginning in 1850 could not be attributed to climatic changes such as the hotter/drier conditions that have prevailed since 1965. Evidence indicates colder and wetter conditions in fact prevailed, and the high stomatal conductance necessary for iWUE increases at the observed rate of the 1850 to 1965 period likely would not have been possible in hotter and drier conditions. The climatic trend of hotter and drier conditions may have played a role in facilitating the switch from S1 to S2, however. Perhaps the most important finding of this study though, is the fact that the unprecedented iWUE increases seen since 1850 did not result in substantially higher growth. Looking at ring-width indices from the trees, the researchers found periods of high growth from relatively recent modern times (1980s-1990s) of equivalent magnitude to other periods from well before 1850. The researchers offer several plausible explanations for this lack of apparent growth, ranging from growth of non-stem components of the three, such as root exudates, to nutrient limitations, for example, the effect of phosphorus on biomass growths in white cedars. Regardless, the results of this study serve as cautionary evidence to those developing dynamic global vegetation models (DGVMs) which rest upon the assumption that higher atmospheric carbon necessarily translates to greater carbon storage via photosynthesis to biomass. Thus the authors conclude: “Our results thus suggest that even in favorable conditions for growth, not all trees can take advantage of elevated levels of ca and iWUE. These mechanisms are not typically taken into account by ecophysiological models and DGVMs which may lead to them overestimating any positive effects bestowed by a higher ca on carbon assimilation and fixation. Predictions of elevated future growth and possible alleviating effects on ca might be overly optimistic if the models do not allow for the possibility of constant or even reduced growth in the context of increasing ca.” Claudie Giguere-Croteau and colleagues published their study “North America’s oldest boreal trees are more efficient water users due to increased [CO2], but do not grow faster,” recently in PNAS. Their study of white cedar trees from the southern edge of the North American boreal forest comprises a dual-isotope analysis of rings from 715-year-old trees located around the shores of Lake Duparquet in Quebec. The extreme old age of the trees is significant in that the sampled growth rings provide hundreds of years of climate and growth condition data prior to the onset of the Industrial Revolution and the concomitant increase in atmospheric carbon dioxide (ca), which, by the criteria of this study, began in 1850. As the authors of the study note, “plants have not been exposed to concentrations [of ca] above 290 ppm for at least 650,000 y, so the dynamic carbon–water coupling that prevailed for several millennia could be disrupted with potential, yet uncertain, impacts on hydro-ecosystem functioning.”Elevated ca, in terms of plants’ physiologic response, is known to correspond to iWUE—a measure of carbon uptake per unit of water lost—though iWUE may also be governed by variables such as assimilation rate (A) and stomatal conductance (gs), and how these variables ultimately affect a plant’s internal carbon (ci). The authors cite three possible scenarios that explain tree acclimation processes in response to rising ca in relation to iWUE. Scenario 1 (S1) supposes a constant ci, in which iWUE increases robustly. Scenario 2 (S2) allows for a constant ci/ca ratio, in which iWUE increases moderately. Scenario 3 (S3) assumes a constant difference between ca and ci, whereby iWUE remains constant. S1 seems the most plausible scenario in the face of the CO2 fertilization effect, though few long-term data exist to further elucidate the specific nature of iWUE in a North American boreal forest, and much uncertainty exists in this respect. Against this background, Giguere-Croteau and colleagues present their findings. Thuja occidentalis L (white cedar). Credit: USDA-NRCS PLANTS Database/Wikipedia © 2019 Science X Network In an age of unprecedented high atmospheric carbon dioxide levels, the question of whether or not plants and trees can utilize excess carbon through photosynthesis is one of paramount importance. Researchers have observed what has been called the CO2 fertilization effect, whereby plants’ rates of photosynthesis increase in response to higher levels of CO2 in the atmosphere, although this is thought to be dependent on various other factors such as temperature, moisture, nutrient availability, etc. A group of researchers from Quebec sought to better understand how the oldest boreal trees in North America—Thuja occidentalis L, white cedar—have responded to higher levels of atmospheric CO2 (ca) in terms of these trees’ intrinsic water use efficiency (iWUE).

TV ads with toy premiums lure kids to eat fast food

first_imgFast food companies advertise children’s meals on TV with ads that feature toy premiums, and the use of these toy premiums may prompt children to request eating at fast food restaurants, a study suggests.The researchers found that the more children watched television channels that aired ads for children’s fast food meals, the more frequently their families visited those fast food restaurants.Using a database they compiled of all fast food TV ads that aired nationally in 2009 in the US, Jennifer A. Emond and colleagues from the Geisel School of Medicine at Dartmouth enrolled 100 children (three-seven years of age) and one of their parents in the study. The parents completed a survey that included questions about how often their children watched each of the four children’s networks, if their children requested visits to the two restaurants, if their children collected toys from those restaurants, and how often the family visited those restaurants.Researchers found that 37 per cent of parents reported more frequent visits to the two fast food restaurants with child-directed TV ads.Fifty-four per cent of the children requested visits to at least one of the restaurants. Of the 29 per cent of children who collected toys from the restaurants, almost 83 per cent requested to visit one or both of the restaurants.Some factors associated with more frequent visits were more TVs in the home, a TV in the child’s bedroom, more time spent watching TV during the day, and more time spent watching one of the four children’s networks airing the majority of child-directed ads. The findings also showed that children’s food preferences may be partially shaped by a desire for the toys featured in TV ads. “Our best advice to parents is to switch their child to commercial-free TV programming to help avoid pestering for foods seen in commercials,” Emond said. The study is scheduled to be published in The Journal of Paediatrics.last_img read more

Landmark environmental jurisprudence

first_imgThe boom in India’s economic growth has resulted in mass urbanisation on a scale rarely witnessed in the history of mankind. The population of several Tier I and II cities has grown exponentially in the last two decades as millions of people seek better economic opportunities. However, this economic growth has come at a tremendous cost to the quality of human life as unplanned urban developments have mushroomed, giving rise to pollution, congestion, and diseases that give rise to living conditions that would be termed “miserable” by western standards. Thus, it comes as no surprise that Indian cities figure at the bottom of the list of any quality of life survey done at the international level. Also Read – Gateway of criminal justiceThe prime reason for this dismal state of affairs is visible everywhere—illegal construction. Developers blatantly violate development control regulations that stipulate mandatory open spaces, recreation grounds, parking, and fire safety.

To make matters worse, enforcement of development control regulations was considered a municipal matter and not as one falling within the scope of the term “environment”. Also Read – Turning a blind eyeOn September 3 this year, the principal bench of the National Green Tribunal (NGT) at New Delhi passed a landmark judgment that, for the first time, brought important principles of town planning within the scope and jurisdiction of the NGT. In its judgment in the matter of Sunil Kumar Chugh v/s Secretary, Ministry of Environment and Forests, New Delhi, Appeal No. 66 of 2014, the NGT held that open spaces, recreational grounds and adequate parking facilities in buildings had an important bearing on the right to life of people. The appellants, Sunil Kumar Chugh and Ravinder Khosla, were residents of the slum redevelopment project being carried on by the developer, M/s Priyali Builders at Antop Hill, Mumbai. They filed an appeal challenging the Environmental Clearance (EC) issued to the developer on March 25, 2014, as illegal and prayed that the same be quashed.In their appeal, the appellants stated that the builder had violated the Environmental Impact Assessment Notification, 2006 by starting construction without EC, way back in 2009. For five years, the developer continued construction without EC. The State Environmental Impact Assessment Authority (SEIAA) of Maharashtra ignored this blatant violation and blindly granted EC to the builder.It was further averred by the appellants that the developer did not provide any recreation ground to the residents. Further, he did not provide any parking spaces for the residents of the rehabilitation tenements, as a result of which, they were forced to park on the street. This severely prejudiced their right to life under Article 21 of the Constitution of India.The case was heard by the principal bench at New Delhi, comprising Justices Swatanter Kumar and U D Salvi, along with expert members D K Agrawal and M A Yusuf. In its judgment, the bench held that the developer had violated the EIA Notification, 2006 and the Environment Protection Act, 1986 by commencing construction without prior EC. Further, by not providing adequate recreation grounds, the developer had severely prejudiced the right to life of the appellants. Consequently, the bench held the developer liable for violating the law and imposed a fine of Rs. 3 crore to be paid into the environmental relief fund maintained under the Public Liability Insurance Act, 1991. Further, taking note of the fact that the developer had provided deficient recreation grounds to the residents, the court directed that a further sum of Rs. 32, 63,600 be paid to the Maharashtra Pollution Control Board (MPCB) for the deficient recreational area in the building. The approved plan of the building was quashed and the builder was directed to submit a fresh plan that would contain adequate parking for all residents of the building and address the shortfalls.During the court proceedings, the developer had claimed that prior EC was not required as the “FSI Area” (Floor Space Index or Floor Area Ratio) of the project was less than 20,000 square metres, the prescribed statutory limit. He claimed that the lift lobby and staircase area were exempt from the computation of built-up area under the EIA Notification. The NGT strongly rejected this argument, stating that the term “built-up area” includes the entire construction area, saleable and non-saleable. It further held that the 2011 amendment to the EIA Notification that clarified the term “built-up area” was clarificatory in nature and would have a retrospective effect from 2006 itself.The booming construction industry in Mumbai has resulted in repeated violations of environmental norms that severely prejudice the right to life of the residents. Innumerable projects commence construction without prior EC. Ex-post-facto clearances have been granted arbitrarily, without imposing any penalty on the developer. The landmark judgment of the NGT in the case of Sunil Kumar Chugh v/s Ministry of Environment and Forests, New Delhi & Others (Appeal No. 66 of 2014) will set a strong precedent in penalising violators and quashing the illegal permissions granted to them. Further, builders will not be able to segregate FSI areas from non-FSI areas and pass off the same as built-up area. This ruling is indeed an important step forward in the effort to save India’s cities from the degrading effects of illegal construction and haphazard urbanisation, which have so far continued unabated.

first_imgKolkata: Demonetisation had harmed the Taant industry in West Bengal, alleged minister of state for Micro Small and Medium Enterprises (MSME) Swapan Debnath, while inaugurating the 12th ‘Banglar taant er haat’ at Central Park mela ground in Salt Lake on Friday. He also informed that the event will be held at Salt Lake instead of Milan Mela ground from now on.”The sales in the fair has increased a lot since 2011. In 2016, the amount was Rs 4.32 crore. In 2017, the amount increased to Rs 5.85 crore. It is expected that the amount will go up this year as well,” said Debnath. Also Read – Rain batters Kolkata, cripples normal lifeAccording to the officials connected with the event, the fair has been organised keeping the upcoming Durga Puja festival in mind. The fair will go on till September 23. “Before puja we Bengali’s usually buy new clothes for ourselves and our family members. Keeping the fact in mind, we selected the date,” said an official from the MSME department.Apart from this, the organisers have thought of some unique steps. Three credit/debit card transaction kiosks have been installed at the mela ground. If any trader with a stall does not posses a card swiping machine, then the kiosks will be there to help them. The customer will be accompanied by a employee of the trader to a kiosk with a valid purchase bill. Operators at the kiosk will swipe the credit/debit card for payment. The amount will be credited to a government-owned account, which will be transferred later to the trader’s account.During the inaugural programme, Debnath unveiled five designer sarees manufactured by Tantuja. He said: “In this year’s fair, 270 stall have been installed. We need to provide more platforms to our taanti brothers and sisters, as instructed by our Chief Minister Mamata Banerjee.”Plastic carry bags have been banned at the fair. Instead of plastic, traders are using bags made of jute and other eco-friendly materials.last_img read more

Designer Ritu Kumars exciting journey

first_imgFashion in the country has undergone drastic changes over the years which wouldn’t have been possible without the contributions of some of the fashion extraordinaire. From a small traditional outlet on the crowded lanes of Kolkata to high-street fashion boutiques on the by-lanes of Paris, London and New York, fashion connoisseur Ritu Kumar has not only evolved as a designer but has also contributed to the evolution of the fashion industry of India, as a whole. Also Read – ‘Playing Jojo was emotionally exhausting’Millennium Post caught up with her when she was recently in the Capital where she was a part of the jury in an event held to inspire and felicitate young-upcoming designers.How does it feel to be a part of the jury and the event?Well I have been a part of the jury for similar events, many times and I truly feel it’s very important to take time out to do that because it’s the future, future of the kids as well as the fashion industry. Very often, they need someone who has been in the industry for a while, has the experience and can give a feedback which will be very objective.   Also Read – Leslie doing new comedy special with NetflixThe present scenario where everyone is fashion conscious, do you feel that this is an advantage for budding designers as they possess the knowledge before setting their foot in the industry?I think so. You know, when I started, there was no fashion in the country and all. There was no indigenous or organic fashion. Also, there were no choices, options or retail, of course today upcoming designers have much more options, they have access to schools, a great access to a variety of fabrics, to the media like yours and I think that’s an advantage. In fact, I think this is one of the reasons why India still has indigenous fashion while the rest of the world doesn’t. Since you have designed a repertoire of bridal wear, what’s your take on the evolution in bridal wear with the modern Indian brides going over the edge while picking up their wedding trousseau?Earlier on there was one occasion and one traditional outfit before the actual ceremony. In all the other ceremonies, most brides were asked to play down and you were not even supposed to be dressed up or seen. So that has changed now and brides today are very participating. They don’t want to hide anymore or shy away from indulging in. Also, they are very inquisitive. They want to have, sometimes, a mix of Indian-western, options to be specific. And now it’s not the case anymore where one is told that you can wear this or can’t wear that. Women, nowadays, enjoy their bodies and they enjoy the clothes they wear.So, in a way are women moving out of their comfort zones?No, they are moving into a comfort zone without being scared. I think it is more than the evolution of Indian women along with the evolution of fashion that has happened. Over the years, women have started to experiment with their looks and try new things.From Miss World Aishwarya Rai to Priyanka Chopra, Princess Diana, you’ve designed for many renowned names of the showbiz, who have you loved designing for, the most?You know, how wonderful it is that there was no one person. I mean, from designing a salwar kameez for Princess Diana to designing for Priyanka when she recently was in LA, I have loved every one of them. You see, there is a time and a moment and also the people you design for, evolve. What they used to wear earlier they don’t really prefer that anymore. In 1994 when Aishwarya won the crown, what she wore then, it’s not what she wears today. And I designed according to their characters and preferences and I don’t impose anything on them other than good craftsmanship.last_img read more

first_imgDarjeeling: The Gorkha Janmukti Morcha (Bimal Gurung faction) suffered another setback with Rohit Thapa, the organisational secretary of Dooars tendering in his resignation from the party.Talking to mediapersons in Siliguri on Monday, Thapa stated that he has resigned as the party has been taking decisions without consulting the leaders and supporters on ground zero. “Since 2008 I have supported and worked on the behest of Bimal Gurung in Dooars.

This time also we are ready to support Bista but where is the Gorkhaland issue. We have supported Bimal Gurung just because of the Gorkhaland issue.” Thapa stated that they are not willing to support Gurung’s politics of self survival. “We were having an all-party meet to decide on a consensus candidate.

We have been kept in the dark constantly,” Thapa said. Without naming the BJP he stated that they are adopting double standards on Gorkhaland. “From the Hills till Sukna its Gorkhaland and once they come to the plains Gorkhaland disappears,” added Thapa. When questioned on whether he would join any other party, Thapa stated that he has not decided on this yet. Recently Swaraj Thapa, a close confidant of Bimal Gurung and advisor, had also resigned from the party.last_img read more

Women find edited Instagram selfies less authentic

first_imgNew York: Women may perceive selfies on Instagram and other social media sites as less authentic if they know it has been edited, a new study suggests. The findings, published in the journal Body Image, suggest that when women believed that selfies of thin and sexualised women had been edited, viewing these images had less negative impact on their mental health. “Women see the edited photos as less authentic and it reduces the negative effect these images can have on them. They know that the online images might not reflect an offline reality,” said lead author Megan Vendemia from The Ohio State University in the US. Also Read – Add new books to your shelfAccording to the researcher, many studies have found that viewing thin and sexualised images of models or others can lead women to put more value on being slender themselves – a line of thinking called thin ideal internalisation. This internalisation can in turn lead to eating disorders or other psychological problems. But the findings suggested that women were less likely to internalise the thin ideal if they believed the pictures they viewed were edited. For the study, the team involved 360 female college students who were told that study was designed to determine how people evaluate images that appear on popular social media sites.last_img read more
