Going With The Flow

The content is provided for information purposes only. Along with colleagues Marek Cieplak from the Polish Academy of Physics in Warsaw and Jayanth R. Banavar at Penn State, Koplik is working on ways that the manipulation of fluids on the smallest workable scale could be managed.Koplik and his colleagues have developed a simulation that shows how fluids can be contained without using the obvious method — small, closed nanotubes. Physical Review Letters published a portion of their work on March 23. Koplik believes that these tubes are not only unnecessary, but also impractical: “A closed nanotube is not easy to fabricate, it is easy to clog, and it is hard to control anything inside of it. Instead of having liquid confined by walls, have it controlled in other ways.”The other way Koplik, Cieplak, and Banavar envision is the use of chemically patterned solids to contain the flow of water. Their system involves a solid that has a specific chemical pattern. This chemical pattern looks like a complex highway, with “roads” that branch out from a main “thoroughfare” and then merge back together or divide into new roads. The patterns are wetting regions. Wetting is a term that describes a portion of the solid that is highly attractive to a liquid or a gas. When one is working on such a small scale, liquids or gases prefer to be near regions of solid that are wetting, while avoiding regions that are not, and gravity is negligible so there is no spillage. The wetting regions are so attractive, explains Koplik, “that it is possible to make fluids flow at the nanoscale without spilling by applying body forces, like electrical or centrifugal forces.”Now that it appears possible to create fluid containment in this manner, new questions crop up, mainly: How does one control the fluid motion in better detail? Answering this question is Koplik’s main interest. “Right now,” he tells PhysOrg.com, “the fluid chooses a branch to follow spontaneously. The idea is to be able to make it go a particular direction.” He is also working on ways to perhaps split the flow that some of the fluid follows one brand at the “fork in the road” and some of it follows another brand. But there is a catch: “You want to be able to ideally control how much goes down one side and down the other. It’s not just a matter of some going here and some going there. You want to have control of the relative volumes.”Another issue Koplik and his colleagues need to address are the different properties of different liquids. One problem Koplik sees is the desire for the fluid manipulated at the nanoscale to be water, which is the preferred liquid in biological and medical settings. However, water is quite volatile and nanoscale volumes of it are likely to evaporate at room temperature, limiting its usefulness at the nanoscale. He is pursuing the idea of having water on a wetting region, surrounded by another, less volatile, liquid to prevent evaporation. The extra effort needed in fabrication may be compensated for by better flow control.If Koplik and his peers can figure out how to harness the system they have discovered, the opportunities in science and technology are numerous. Applications including microscopic fluid analysis and chemical detection in “labs on chips” would be possible. Additionally, Koplik points out the advantages of being able to efficiently move molecules around. And in biological and medical research, controlling fluid flow at the nanoscale can mean a better detection of pathogens.“This is on the verge of being commercially viable,” explains Koplik. “We are trying to anticipate the direction things are going, which is smaller and smaller. We’re trying to develop techniques and theories so that when the commercial community wants to go there, they can.”By Miranda Marquit, Copyright 2006 PhysOrg.com Citation: Going With The Flow (2006, March 29) retrieved 18 August 2019 from https://phys.org/news/2006-03-going-with-the-flow.htmlcenter_img As our technology shrinks ever smaller, commercial manufacturing and biological and medical research follows suit. Sometime in the relatively near future, asserts Joel Koplik, a professor at the City College of the City University of New York, there will be a need for new techniques that allow commercial and research interests to control liquids at the nanoscale.last_img read more


Vikings in English grave had filed teeth

The content is provided for information purposes only. An illustration of Vikings on a boat. (Image via Wikipedia) The gravesite, or burial pit, found in Weymouth, Dorset, on the southern coast of England two years ago, was filled with the bodies of 54 headless skeletons along with 51 skulls, all of whom are believed to be the remains of marauding Vikings from northern Europe during the time period 970 to 1025, which would make it just before the infamous Norman conquest of 1066 that transformed England from a mostly Anglo-Saxon civilization to one dominated by the French Normans.The bodies in the pit all show evidence of a mass execution, in that most had multiple cut wounds, and of course, the fact that their heads were cut off. Radio carbon dating was used to determine how long the bodies have been there and isotope analysis of teeth showed that the bodies were all men from the north of Europe, one even from above the Arctic Circle. The late 900s would place the time of death in the same time frame as Viking raids on the Anglo-Saxons that lived there at the time. Also, the fact that Weymouth is a port city on the English Channel would have made it a prime target for such raids.The teeth filings appeared to be the work of a skilled craftsman, according to Oxford Archaeology project manager David Score, who spoke with the BBC about the find. He suggested the filings were likely made to frighten opponents, though in this case, it appears the ploy failed, as he and his party wound up in the pit with their heads sliced off.The pit was discovered in 2009 by a road crew, and a team of archeologists has been studying the remains since that time. The scientists are quick to point out that research is still ongoing, and while the evidence is strong that the remains are those of early Vikings, it still hasn’t been proven definitively, thus far. Complicating the case is the fact that no clothing, buttons or any other artifacts were found in the pit, which means the victims were stripped naked before their execution.

Though it’s not known exactly why, whether to instill fear in victims, to impress comrades or even to show rank, the filing of the teeth, likely a painful process, is a unique find, in that it is something that is rarely seen in early European history.last_img read more


Finland team uses Earths magnetic field for phone indoor positioning system

first_img Google announces Floor Plan app for venue owners Explore further They now have a smartphone app that uses the Earth’s magnetic field to help people—in businesses and developers—that can help people tell exactly where they are. It can provide smartphone users a way to make use of indoor maps and can also provide developers with a toolbox for positioning-focused applications.They authored a paper, “Ambient magnetic field-based indoor location technology – Bringing the compass to the next level,” that explains their notion that the earth’s magnetic field is not only a useful factor for animals but also for true navigation for modern-day applications. © 2012 Phys.org Citation: Finland team uses Earth’s magnetic field for phone indoor positioning system (2012, July 10) retrieved 18 August 2019 from https://phys.org/news/2012-07-finland-team-earth-magnetic-field.html “Some animals, such as spiny lobsters, are not only able to detect the direction of the Earth’s magnetic field, they can even sense their true position relative to their destination. This means these particular animals are able to derive positional information from local cues that arise from the local anomalies of the Earth’s magnetic field.” Likewise, they said, modern buildings with reinforced concrete and steel structures have unique, spatially-varying ambient magnetic fields that can be used for positioning, though on a far smaller spatial scale. They said that each building, floor and corridor creates a distinct magnetic field disturbance that can be measured to identify a location and generate a map.“In principle, a non-uniform ambient magnetic field produces different magnetic observations, depending on the path taken through it. In IndoorAtlas’ location technology, anomalies (fluctuations) of ambient magnetic fields are utilized in indoor positioning.” Dr.Janne Haverinen, the head of the project, said both what they know about magnetic fields and what they saw in the smartphone marketplace combined to drive their product development. “When iPhone and Android phones arrived with built-in compasses, we realized that we could develop an innovative indoor navigation solution by applying our digital signal-processing expertise,” said Haverinen. As such, New Scientist points out the interesting feature of this technology: Compasses don’t normally work inside buildings because metallic structures disturb the Earth’s magnetic field, while IndoorAtlas can make use of these disturbances to create a unique map within each building. (Phys.org) — Finland-based engineers have worked up a novel approach toward an indoor positioning system (IPS) inspired by the way certain animals–from homing pigeons to spiny lobsters–navigate their way with the help of cues that arise from local anomalies of the earth’s magnetic field. The researchers have formed a company with seed capital investment to commercialize their approach. Namely that approach has resulted in a smartphone app that uses magnetic fluctuations to map indoor locations. Aptly named IndoorAtlas, the company is a spinoff from their University of Oulu beginnings. This document is subject to copyright.

The company is offering a “toolbox” made of three components, Floor Plans, Map Creator, and an app creator using the company API. Before indoor positioning information can be used on a smartphone, developers need to collect magnetic field information and overlay the information with a floor plan. They need to create an image of the location’s floor plan and then walk through the location while collecting data. IndoorAtlas says their toolbox can create indoor location-awareness applications for a range of applications, such as to guide people inside shopping centers and airport terminals.As for smartphone use, the technology is described as a software-only location system that requires nothing more than a smartphone with built-in sensors. No radio access points or other external hardware infrastructures are necessary. The accuracy in IndoorAtlas’ technology in modern buildings ranges from 0.1 meter to two meters.last_img read more


Increase in bear infanticide linked to hunting

The research was conducted primarily to investigate the population dynamics of large, long-lived mammals. Bear hunting harvests in the area were monitored and the female bears were tagged with radio transmitter implants from 1990 to 2011. During the study, varying degrees of ‘hunting pressure’ were observed. Bear-hunting season lasts from late August or early September until October 15th or when the quota for a designated area has been reached. Only solitary bears, both male and female, are hunted. Family groups, including solitary cubs and yearlings, are protected from hunting. Female brown bears provide long periods of maternal care (between 1.5 and 4.5 years). The long periods of care reduce the availability of reproductive females. Unlike their North American counterparts, Scandinavian brown bears have an increased propensity towards sexually selected infanticide (SSI). In cases of limited mating possibilities, it may be advantageous for a member of a sex (usually male) to eliminate the offspring of another member of the same sex to prompt a member of the opposite sex into a reproductive cycle. A female brown bear may become receptive only two to four days after losing her young during the mating season. As expected, the bear population declined during times of high hunting pressure and grew under low hunting pressure . The analysis of the data indicated that the 2 percent decline in fecundity rates (reproductive rates of a population) was greater than expected, estimated after a period of high hunting pressure. Cub survival is important to population growth, with cub mortality reaching 81 percent over the course of the study. The cub loss is mostly attributed to SSI during mating season (mid-May to mid-July). The data showed that without SSI , and with other factors for survival being equal, cub survival would be 81percent higher. This illustrates that other factors besides hunting are responsible for the overall local population decline and that male behaviour appears to have an important effect on population dynamics. The high hunting pressure resulted in 57 percent of males harvested in 2006–2011, compared with 52 percent in 1990–2005 (low hunting pressure). With more males bears killed, there was a higher likelihood of other male bears encountering cubs and females with cubs that are not related to the male, and thus SSI occurrence increased, causing the larger decrease in bear population. Other indirect causes for the bear population decline due to hunting are also influenced by the male bear population. In order to counter SSI, female bears (with cubs) during the mating season avoid good habitats in favour of those in close proximity to humans. This has detrimental effect on the diet of the bear and could subsequently influence female reproductive output, lowering the fecundity. The study hopes these new findings will be used when establishing hunting quotas and management policies.last_img read more


Carbon dioxide captured from air can be directly converted into methanol fuel

first_img © 2016 Phys.org (Phys.org)—For the first time, researchers have demonstrated that CO2 captured from the air can be directly converted into methanol (CH3OH) using a homogeneous catalyst. The benefits are two-fold: The process removes harmful CO2 from the atmosphere, and the methanol can be used as an alternative fuel to gasoline. The work represents an important step that could one day lead to a future “methanol economy,” in which fuel and energy storage are primarily based on methanol. Journal information: Journal of the American Chemical Society Homogeneous catalysis: ruthenium phosphine complex hydrogenates carbon dioxide to make methanol Using a new catalyst, researchers have demonstrated that up to 79% of the carbon dioxide captured from the air can be converted into methanol. Credit: Gregory Heath, CSIRO More information: Jotheeswari Kothandaraman, et al. “Conversion of CO2 from Air into Methanol Using a Polyamine and a Homogeneous Ruthenium Catalyst.” Journal of the American Chemical Society. DOI: 10.1021/jacs.5b12354center_img The study was led by G. K. Surya Prakash, a chemistry professor at the University of Southern California, along with the Nobel laureate George A. Olah, a distinguished professor at the University of Southern California. The researchers have published their paper on the CO2-to-methanol conversion process in a recent issue of the Journal of the American Chemical Society. “Direct CO2 capture and conversion to methanol using molecular hydrogen in the same pot was never achieved before. We have now done it!” Prakash told Phys.org. Over the past several years, chemists have been investigating various ways of recycling CO2 into useful products. For example, treating CO2 with hydrogen gas (H2) can produce methanol, methane (CH4), or formic acid (HCOOH). Among these products, methanol is especially attractive because of its use as an alternative fuel, in fuel cells, and for hydrogen storage. The chemical industry currently produces more than 70 million tons of methanol annually because the simple compound also serves as a building block for many larger compounds, including two of the most highly produced organic compounds, ethylene and propylene, which are used to make plastics and other products.A key factor in the CO2-to-methanol conversion process is finding a good homogeneous catalyst, which is essential for speeding up the chemical reactions so that methanol can be produced at a fast rate. The problem is that these reactions require high temperatures (around 150 °C), and unfortunately the heat often causes the catalysts to decompose.In the new study, the researchers developed a stable catalyst based on the metal ruthenium that does not decompose at high temperatures. The catalyst’s good stability allows it to be reused over and over again for the continuous production of methanol. “Developing stable homogeneous catalysts for CO2 reduction to methanol was a challenge,” Prakash said. “Majority of the catalysts stopped at the formic acid stage. Furthermore, we needed a catalyst that could reduce carbamates or alkylammonium bicarbonates directly to methanol. We have achieved both with our catalyst.”With the new catalyst, along with a few additional compounds, the researchers demonstrated that up to 79% of the CO2 captured from the air can be converted into methanol. Initially the methanol is mixed with water, but it can be easily separated out by distillation.Looking at the work from a broader perspective, the researchers hope that it may one day contribute to a methanol economy. This plan involves developing an “anthropogenic carbon cycle” in which carbon is recycled to supplement the natural carbon cycle. In nature, carbon is continuously being exchanged, recycled, and reused among the atmosphere, oceans, and living organisms, but nature cannot recycle the carbon from fossil fuels as quickly as humans can burn them. Humans could counteract some of the CO2 we release by converting some of the carbon back into an energy source such as methanol.More information on the anthropogenic carbon cycle can be found in this Perspective piece by Olah, Prakash, and Alain Goeppert.As a next step, the researchers plan to lower the catalyst operating temperature and improve its efficiency.”We will continue the studies to develop more robust catalysts that work around 100 to 120 °C,” Prakash said. “We would like to perform the chemistry in a preparatively useful way, wherein there are no solvent or reagent losses.” Citation: Carbon dioxide captured from air can be directly converted into methanol fuel (2016, January 27) retrieved 18 August 2019 from https://phys.org/news/2016-01-carbon-dioxide-captured-air-methanol.html Explore further This document is subject to copyright.

Generalized Hardys paradox shows an even stronger conflict between quantum and classical

first_img Explore further In 1993, physicist Lucien Hardy proposed an experiment showing that there is a small probability (around 6-9%) of observing a particle and its antiparticle interacting with each other without annihilating—something that is impossible in classical physics. The way to explain this result is to require quantum theory to be nonlocal: that is, to allow for the existence of long-range quantum correlations, such as entanglement, so that particles can influence each other across long distances. More information: Shu-Han Jiang et al. “Generalized Hardy’s Paradox.” Physical Review Letters 120, 050403 (2018). DOI: 10.1103/PhysRevLett.120.050403, Also at arXiv:1709.09812 [quant-ph] This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. By building the most general framework for the n-particle Hardy’s paradox and Hardy’s inequality, the results of the new paper provide a stronger Hardy’s paradox, and can also detect more quantum entangled states. As the success probability for the three-qubit generalized Hardy’s paradox reaches 0.25, the researchers are very hopeful that it will be observed in future experiments. Credit: Jiang, et al. © 2018 American Physical Society So far, Hardy’s paradox has been experimentally demonstrated with two particles, and a few special cases with more than two particles have been proposed but not experimentally demonstrated. Now in a new paper published in Physical Review Letters, physicists have presented a generalized Hardy’s paradox that extends to any number of particles. Further, they show that any version of Hardy’s paradox that involves three or more particles conflicts with local (classical) theory even more strongly than any of the previous versions of the paradox do. To illustrate, the physicists proposed an experiment with three particles in which the probability of observing the paradoxical event reaches an estimated 25%.”In this paper, we show a family of generalized Hardy’s paradox to the most degree, in that by adjusting certain parameters they not only include previously known extensions as special cases, but also give sharper conflicts between quantum and classical theories in general,” coauthor Jing-Ling Chen at Nankai University and the National University of Singapore told Phys.org. “What’s more, based on the paradoxes, we are able to write down novel Bell’s inequalities, which enable us to detect more quantum entangled states.”As the physicists explain, Hardy’s paradox involves inequalities that correspond to the inequalities in Bell’s theorem—a theorem showing that quantum mechanics must violate either locality or realism. As previous research has shown, Hardy’s paradox can be interpreted in terms of inequalities by considering the probabilities of certain events occurring. Suppose that the probabilities that A < B, B < C, and C < D are all zero. In the classical world, it would then be impossible to have A < D. But in Hardy's paradox, A < D occurs with some nonzero probability, in contrast with classical predictions."Put simply, Hardy's paradox states that a classically impossible sequence of events from end to end—just imagine a snake devouring its tail—as it were, are nonvanishingly possible in the quantum region," Chen said. "This is really surprising."In the future, the physicists plan to further explore the connections between the generalized Hardy's paradox and Bell's inequalities. In regards to experiments, a group at the University of Science and Technology of China has begun to perform the photon-based experiment to verify the stronger Hardy's paradox.center_img Journal information: Physical Review Letters © 2018 Phys.org Citation: Generalized Hardy’s paradox shows an even stronger conflict between quantum and classical physics (2018, February 1) retrieved 18 August 2019 from https://phys.org/news/2018-02-hardy-paradox-stronger-conflict-quantum.html Physicists resolve a paradox of quantum theorylast_img read more


DOJ Increases Power Of Agency Running Immigrat

first_imgDOJ Increases Power Of Agency Running Immigration Court… Susan Walsh by NPR News Richard Gonzales 8.24.19 2:44am The Trump administration is making changes to the agency that operates the nation’s immigration court system, a move immediately denounced by the immigration judges’ union as a power grab.The agency is called the Executive Office for Immigration Review and it is an arm of the Justice Department. Under the interim rule announced Friday, the agency’s director will have the power to issue appellate decisions in immigration cases that have not been decided within an allotted timeframe. It also creates a new office of policy within EOIR to implement the administration’s immigration policies.The head of the immigration judges’ union accused the administration of trying to strip power away from judges and turn the immigration court system into a law enforcement agency.”In an unprecedented attempt at agency overreach to dismantle the Immigration Court, the Department of Justice, Executive Office for Immigration Review (EOIR) today published a new interim rule, effective next Monday, which takes steps to dismantle the Immigration Court system,” Judge Ashley Tabaddor, president of the National Association of Immigration Judges, said in a statement. “DOJ’s action ends any transparency and assurance of independent decision making over individual cases.”The new rule, first reported by The Associated Press, comes after the administration announced an effort to decertify the immigration judges’ union. The judges, 440 in total, are employees of the Justice Department and not part of the independent judiciary. The Trump administration has also imposed quotas on judges in an effort to speed up deportations and reduce the backlog of more than 900,000 cases pending in immigration courts.Tabaddor said the administration is trying to concentrate its power over immigration proceedings.”The new rule is a wolf in sheep’s clothing,” Tabaddor said. “While couched in bureaucratic language, the impact of this regulation is to substitute the policy directives of a single political appointee over the legal analysis of non-political, independent adjudicators.”The EOIR did not respond to a call for comment.Earlier this week, the EOIR sent the immigration judges a newsletter containing a blog post from VDare, an anti-immigration website, which included an anti-Semitic reference, according to Tabaddor. After she protested, Justice Department officials said some information included with the newsletter had been compiled by a third-party contractor and should not have been distributed.”The Department of Justice condemns anti-Semitism in the strongest terms,” Kathryn Mattingly, a spokeswoman for EOIR told BuzzFeed.Copyright 2019 NPR.

State government plans to bring back Kolkatas iconic doubledecker buses

first_imgKolkata: The state government is seriously considering a proposal to reintroduce the double-decker buses on city roads.Following the direction of Chief Minister Mamata Banerjee, a senior official of the state Transport department went to London and conducted a survey regarding the plying of double-decker buses.It may be mentioned that the Chief Minister saw double-decker buses during her visit to London and urged the state Transport department officials to take necessary steps to reintroduce double-decker buses in the city. Also Read – Rain batters Kolkata, cripples normal lifeSuvendu Adhikari, the state Transport minister, informed the state Assembly on Wednesday that the government is taking the proposal of reintroducing double-decker buses into serious consideration. He further stated that only a few buses will be reintroduced.The double-decker buses will be open-top in design. It may be mentioned that the final decision on whether they would be meant mainly for tourism or daily commuters as well, is yet to be taken. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAt the same time, other necessary aspects for operating the double-decker buses are also yet to be discussed.Double-decker buses were introduced by private operators in Kolkata in the 1930s. In 1932 when the Indians started boycotting British goods following Mahatma Gandhi’s Civic Disobedience Movement, the English cricket skipper Douglas Jardine of the infamous Bodyline Series on his way back to England stayed in Kolkata (then Calcutta) and through advertisements published by the British government, urged the commuters to avail double-decker buses and trams. After independence, Calcutta State Transport Corporation was set up and double-decker buses were introduced in Calcutta by the state government. The buses used to ply on several routes including bus number 2, which used to ply from Ballygunge to Pikepara and number 2B, from Ballygunge to Baghbazar.Bus number 33 used to ply from Chetla to Pikepara while L9 used to ply from Golpark to Dunlop. L20 used to ply from Barrackpore to Esplanade, while 5 and 6 used to ply from Garia to Howrah. Bus number 16 used to ply from Dhakuria to Botanical Garden. From Howrah to Gouribari, bus number 15 used to ply, which was later extended to Ultadanga.The fleet had been discarded from 1985 in phases, as spare parts of Leyland buses became unavailable. Also, it became a very expensive affair to import Leylands from England. Both the engines and the coaches were manufactured by Leyland.last_img read more


Honey were sugaring the Presidents estate

first_imgLying untapped for ages, Sir Edwin Landseer Lutyens’ largest Presidential edifice in the world – Rashtrapati Bhawan – has now caught the attention of Prime Minister Narendra Modi’s dream project ‘Sweet Revolution’! Taking cognizance of the nectar-producing gardens with abundant flora and fauna, including lush trees of mangoes, Indian blackberries (jamun), Neem and drumsticks, the Khadi and Village Industries Commission (KVIC) launched an apiculture training course for the gardeners of President’s Estate on April 16 at Rashtrapati Bhawan premises. As many as 50 gardeners participated in the course, started by KVIC. Also Read – Add new books to your shelfGiving the details of the program, V K Saxena, the KVIC Chairman, said that the gardeners were apprised of the comprehensive scope and significance of apiculture – important considerations and tips to care and maintain the apiaries and the value of beekeeping in maintaining the flora and fauna. “After training, the KVIC will install as many as 500 bee-boxes in different phases in the Rashtrapati Bhawan premises – having huge greeneries. Besides producing more than 12,500 kilograms of high-quality honey and 300 kilograms of good-quality wax every year, apiary will also boost the flora and fauna in and around the President’s estate and increase the crop yield there by at least 25 percent,” he said, adding, “It is a joint project of KVIC and New Delhi Municipal Corporation (NDMC). The KVIC has also decided to set up as many as 5,000 bee-boxes this year in different gardens of Delhi, including Lodhi Garden, Talkatora Garden, and Nehru Park, apart from the various reserved forest areas in Delhi.” Also Read – Over 2 hours screen time daily will make your kids impulsiveMr Saxena further said that the KVIC’s apiculture experts delved upon honey bee species, colony organisation, division of labour and life cycle of honey bees; management of honey bee colonies during different seasons. “The gardeners will also get practical training of examination of honeybee colonies, acquaintance with apicultural equipment, identification and management of bee enemies and diseases, honey extraction, wax purification, and management of bee colonies during all seasons,” he said, adding, “Our objective is to make the sweet nectar available to each and every family for their daily consumption, following the call of ‘Sweet Revolution’ given by our Prime Minister. Honey helps to boost immunity and purifies the blood. Its medicinal value protects the body from major health problems like heart ailments and cancer.” In the meeting with the officials of Rashtrapati Bhawan, held last month, the KVIC Chairman had suggested the Secretary to the President, to launch the ‘Honey Mission’ from there by setting up 500 bee-boxes, for which they agreed. On May 9, the KVIC had launched a five-day beekeeping course for inmates of Jail no 5 in Tihar.Omita Paul, the Secretary to the President, in her address, said that this initiative from KVIC would not only increase the yield of horticulture and floriculture in and around the President Estate, rather it would also boost empowerment among the women associated with different self-help groups. “The beekeeping program will be a bonanza for the 16,000 flowers and plants, recently placed in the Rashtrapati Bhawan premises. As this area has abundant trees, suitable for pollination, it will massively increase the yield of the crops in the neighboring areas,” she said.last_img read more


Tagore in Shorthand A tribute to the Kobi Guru

first_imgArtist Indrajit Nattoji presented a unique collection of paintings, that delves into Kobi Guru’s literary works through handwriting his poems and songs in his image. Titled “Tagore in shorthand”, the collection which was displayed at ICCR, was created using ink and paint on paper. Each art-work showcases one of Tagore’s literary works written in his image. Portraits range from Tagore as a young man to his later years. Talking about his inspiration, Nattoji said, “I have been drawing and painting from the time I recall my earliest childhood memories. When I was studying at the National Institute of Design, long before the digital renaissance, we used to take notes, write scripts, stories and with pen, pencil and paper. Computers were a distant concept at that time and nor were we allowed near one. Recently, I started using handwritten words and sentences to create forms while drawing over words when I made mistakes. As I was drawing while writing, the lines took on a life of their own. I started writing while creating an image and I created images while writing. I then added some paint and colour. Shorthand art anyone?” Also Read – Add new books to your shelfA student of NID, Ahmedabad, Nattoji has won the Singapore Promax BDA Asia Awards, Razorfish Rocket Award for Rising Talent and Best Station ID. Currently, he is writing his next feature film, while conceptualizing, directing and producing three film installations for India’s first Museum on Indian Music in Bangalore and continuing to make Ad-Films.When asked why he chose Tagore, the artist said, “The Bengali ‘force’ in me has always been strong. I have been brought up with the mandatory staple of Tagore songs, poems and stories. Recently I was in the middle of an animation project where I had taken on a part of the animation where one had to do hands-on drawings digitally. My mother had organized a small function and get together for Robindro Jayanti and had asked me to draw a portrait of Tagore and add a quote from his works. I was already drawing frames for my animation with my newly acquired Ipad and Apple pencil. I quickly combined the words ‘Pochishe Boishak’ into an image of Tagore. It was spontaneous and intuitive. It turned out quite interesting and was much appreciated by everyone. That’s how this project took birth.” What asked about the plans with this journey of painting, he said,”I hope to take this further with interpretations of more of his works in handwritten drawing style with larger formats of drawing, painting, screen prints, woodcuts, digital art and large-scale animation and film installations.”last_img read more
