In new hybrid chip molecules are memories

first_img New record: 3-D-printed optical-electronic integration As scientists strive to satisfy the growing demand of the digital era for faster, smaller, and cheaper electronics, one of the most promising technologies is hybrids. Hybrid ICs (integrated circuits) consist of a combination of different technologies: micro, nano and molecular. Although currently scientists still face a handful of challenges in the development of hybrid ICs, the technique looks promising to produce the one of the highest memory densities yet – a whopping 100 billion bits per square centimeter. As the team wrote, their first major problem they face is “the set-up of economically sustainable technology for the preparation of 1011 cross-points cm-2.” For problems such as synthesizing and grafting the molecules, as well as organizing the writing linkages in the microelectronic circuit, the scientists offered low-cost solutions (e.g. using self-alignment rather than expensive electron beam lithography) to achieve the necessary scaling. Considering the number of parts on a chip – 10 billion bits, 200,000 wires, 256 sense amplifiers and ten million transistors occupy each crossbar of area 2.5 square cm – such scaling is no small feat (figuratively speaking, at least). Although other questions – such as reliability of the molecules –would require further specifications, Cerofolini and Mascolo conclude that micro-nano-mole ICs have potential.“That ‘potential’ does indeed transform into ‘practical’ requires that the techniques of deposition, oxidation and anisotropic etching be integrated in a cluster tool permitting the repetition of the unit cycle in a relatively short time,” the scientists wrote. “…and that the chemical, rheological, etc. properties that are observed on the submicrometer length scale continue to hold true on the nanometer length scale.”Citation: Cerofolini, G. and Mascolo, D. “A hybrid micro-nano-molecular route for nonvolatile memories.” Semiconductor Science & Technology. 21 (2006). 1315-1325.By Lisa Zyga, Copyright 2006 PhysOrg.com This hypothetical molecule is a candidate for mimicking a flash memory cell.

The inset drawing shows the molecules that link the lower and upper sides of the crossbar and “mimic the behavior of a flash memory cell.” Photo credit: Cerofolini, G. et al.center_img “These hypothesized molecules are able to mimic the structure and functioning of a flash memory cell,” the team wrote. “If the molecule admits two electronic states characterized by largely different conductivity … the whole structure may be viewed as a hybrid nano-micro IC with bit density of the order of 1011 cm-2.”The challenges that Cerofolini and Mascolo identified generally revolve around two aspects: production cost and scalability. In the IC industry, money is spent on the front side of the process: if you can design the architecture for a sufficiently small (i.e. dense) chip at a feasible assembly cost, there will be enough uses (computers, cell phones, PDAs, etc.) that profits will more than make up for design costs. Citation: In new hybrid chip, molecules are memories (2006, August 8) retrieved 18 August 2019 from https://phys.org/news/2006-08-hybrid-chip-molecules-memories.html In preparation for fabricating hybrid ICs, scientists Gianfranco Cerofolini and Danilo Mascolo from STMicroelectronics in Italy have analyzed the current state of the required technologies. They then defined and generated solutions for the greatest challenges, and predicted the most successful route to mass fabrication of hybrids for nonvolatile memories (which is memory that can be stored even after power is turned off, e.g. flash). “We have proposed an architecture allowing the mass scale production of hybrid ICs on the 0.1 Tbit [trillion] integration scale,” wrote the team in a recent issue of Semicounductor Science & Technology. “All solutions to factors limiting the development of the technology require the adaptation of already existing technologies to the proposed architecture.”In their hybrid set-up, the scientists start with a microelectronic silicon part, which controls a nano crossbar, where each cross point hosts up to 10,000 molecules – hence, a “micro-nano-mole IC.” It’s the individual molecules that act as memory devices, as they can have two different electrically conductive states (low and high) which code the bits. A molecule captures an electron, causing a current to save the state by switching off writing potential. To erase, the captured electron can be forced to tunnel away. (Electron tunneling, an effect of quantum mechanics, occurs due to the wavelike nature of electrons, enabling the particles to “tunnel” across a forbidden zone and emerge in a different position, not actually having been in between.)

Study shows bees use visual rate of expansion of ground for perfect

first_img Journal information: Proceedings of the National Academy of Sciences Honeybees use visual cues to land safely on vertical surfaces. Credit: Emily Baird, Lund University Explore further More information: A universal strategy for visually guided landing, PNAS, Published online before print October 28, 2013, DOI: 10.1073/pnas.1314311110AbstractLanding is a challenging aspect of flight because, to land safely, speed must be decreased to a value close to zero at touchdown. The mechanisms by which animals achieve this remain unclear. When landing on horizontal surfaces, honey bees control their speed by holding constant the rate of front-to-back image motion (optic flow) generated by the surface as they reduce altitude. As inclination increases, however, this simple pattern of optic flow becomes increasingly complex. How do honey bees control speed when landing on surfaces that have different orientations? To answer this, we analyze the trajectories of honey bees landing on a vertical surface that produces various patterns of motion. We find that landing honey bees control their speed by holding the rate of expansion of the image constant. We then test and confirm this hypothesis rigorously by analyzing landings when the apparent rate of expansion generated by the surface is manipulated artificially. This strategy ensures that speed is reduced, gradually and automatically, as the surface is approached. We then develop a mathematical model of this strategy and show that it can effectively be used to guide smooth landings on surfaces of any orientation, including horizontal surfaces. This biological strategy for guiding landings does not require knowledge about either the distance to the surface or the speed at which it is approached. The simplicity and generality of this landing strategy suggests that it is likely to be exploited by other flying animals and makes it ideal for implementation in the guidance systems of flying robots.Press release Swedish team hope to create buzz in fight against bee deaths When humans try to teach robots how to land they use all sorts of sophisticated technology, most of which is geared towards measuring how far away the ground is, how fast the vehicle is traveling and in which direction. The team working on this new effort at the Australian National University found that bees use a far simpler approach—they note how fast the target appears to be expanding as they move towards it, and adjust their speed accordingly.The idea is that as an object moves closer to the ground, the ground and everything on it appears to expand. If that same object moves at a constant rate, the ground seems to expand at an accelerating rate. On the other hand, if the object adjusts its speed so that the object appears to expand at a constant rate, the object will slow, resulting in zero speed at the touchdown point. And that, the researchers found, is exactly how bees land so well despite having very little brains. The researchers discovered this by filming bees as they flew and landed in their lab, and then analyzed their flight behavior. They also added a spinning spiral disk as a backdrop. If a spiral is drawn and then spun in one direction, and then approached, it appears as if the surface is expanding faster than it really is—spun the other way, it appears as if the surface is expanding slower than it really is. As the bees approached the spiral to land, they adjusted their speed and either came in too slow or too fast, proving they were using visual expansion information to control their landings.The researchers believe their findings should prove helpful for those programming drones or other robotic craft to land on their own—allowing for an inexpensive way to land without broadcasting radar signals to others in the vicinity.center_img © 2013 Phys.org (Phys.org) —An international team of researchers has found that bees use a simple visual technique when landing, either horizontally or vertically. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they filmed bees landing in their lab and in studying the tape discovered how it is they manage to land nearly perfectly every time.

Male St Andrews Cross spiders sniff web pheromones to determine suitability of

first_img Explore further More information: Can males detect the strength of sperm competition and presence of genital plugs during mate choice? Behavioral Ecology (2014) DOI: 10.1093/beheco/aru045AbstractFemale reproductive status can have strong selective effects on male mating strategies due to the threat of sperm competition, which may explain why males prefer virgin over mated females. However, in mating systems with female multiple mating rates and mating plugs, males should not only respond to the risk but also to the level of sperm competition and should be sensitive to the interference from mating plugs. In the orb-web spider Argiope keyserlingi, females possess paired sperm-storage organs facilitating separate sperm storage from different males. Males are limited to 2 copulations due to mutilation of their paired genitals (pedipalps). By conducting binary choice experiments, we tested whether males of different mating status can distinguish between females that mated with 1 or 2 males and whether single-mated males discriminate between single-mated females with matched or unmatched virgin genital openings. Furthermore, we investigated whether males adapt their mating strategies to the intensity of sperm competition by providing males with varying qualities of females in their immediate vicinity. Our results demonstrated that males are sensitive to the level of sperm competition and preferred single-mated females over double-mated females. However, they failed to identify single-mated females whose virgin genital opening matched their unused pedipalp, which is required due to their fixed ipsilateral insemination. Surprisingly, males never mated twice with the same female independently of the quality of surrounding females. This suggests that the benefits from searching and mating with a different female are greater than the benefits of monopolizing the female by mating twice with her. © 2014 Phys.org Journal information: Behavioral Ecology This document is subject to copyright.

Argiope keyserlingi. Credit: James Niland/Wikipediacenter_img (Phys.org) —A trio of researchers, two with the University of Hamburg in Germany and a third with Macquarie University in Australia has discovered that male St. Andrew’s Cross spiders sniff the webs of female spiders to determine if they are suitable for mating attempts. In their paper published in the journal Behavioral Ecology, the team describes how they conducted experiments on several specimens of the species in their lab and discovered that male spiders could “smell” pheromones on the females web and used that information in deciding whether to attempt copulating with them or not. St. Andrew’s Cross spiders of both genders have dual sex organs—a left and a right. To copulate, the organs from both genders must match, i.e. right male to right female or left to left, or things won’t work. Furthermore, when a male mates with a female, his organ (pedipalp) breaks off, forming a plug preventing other males from mating with that female’s organ. The end result is that both genders can only mate twice.But how do male spiders know if a female has already mated twice? Climbing onto her web for a closer look is dangerous, if the (much larger) female is hungry, she’s likely to eat the intruder if both of her organs are plugged. To find out, the researchers placed a male on a wooden peg that two females had used to anchor their webs. The researchers found that the male was able to tell if the female was done mating by simply sniffing her web—he was able to pick up telltale pheromones, and thus avoid the females that provided no reproductive opportunity. Sadly, the sniff test was not able to also tell the male if he and the female had compatible organs remaining (left to left or right to right) for mating, thus, there was still some degree of risk in venturing onto the web.Interestingly, the team also found that the males also would not mate with the same female twice, regardless if all other females in the vicinity were incompatible or already doubly mated. Such a strong predisposition suggests the urge to spread genes was stronger even than the urge to procreate.

Japan announces plans to send probe to Martian moon

first_img © 2015 Phys.org Citation: Japan announces plans to send probe to Martian moon (2015, June 12) retrieved 18 August 2019 from https://phys.org/news/2015-06-japan-probe-martian-moon.html Japan’s space agency JAXA has announced its intention to send a spacecraft to one of Mar’s moons, collect a sample from its surface and then return to Earth to allow for analyzing the sample. If successful, it would be the first human-made craft to land on one of Mar’s moons. Japan planning moon mission: space agency Credit: ESA/DLR/FU Berlin (G. Neukum)center_img Explore further As spacecraft technology has improved, mission objectives have intensified, from simple probes that travel through space sending back data, to sophisticated craft that are able to land on other celestial bodies and then come home—JAXA successfully landed a craft (Hayabusa) on an asteroid, collected samples and returned them to Earth in a mission running from 2003 to 2011. Also the European Space Agency landed the probe Rosetta on a comet just last year. Plans for the new Japanese mission have not been finalized yet, as it appears they are still in the making. The project also still needs funds approved by the government—approximately $241 million. The target would be either Phobos or Deimos, the two moons that orbit the red planet. JAXA is looking at a preliminary date of 2022 for launch. Such a mission is not without risk, Russia announced the same goals, built a probe and set it atop a rocket, but the craft never even made it out into space—it crashed shortly after launch back in 2011, marking a setback for the Russian space program.If JAXA succeeds in its mission, it is believed samples brought back from either moon could help explain its origin (some scientists believe both moons, because they are so tiny, are actually asteroids captured by Mar’s gravity) and perhaps help answer questions surrounding the disappearance of water from Mars’ surface. It could also help manned mission plans for Mars, some of which have called for first landing humans on one of the moons, and using it as a stepping stone—because it has less gravity it would be a lot easier to land on a moon than another planet—shuttling between Phobos or Deimos seems to be a lot safer option. Just last week, NASA announced plans to build a base on tiny Phobos—at just ten miles across, it is rather like a deserted island in the sea of space. This document is subject to copyright.

How Much Leisure Time Do the Happiest People Have

first_imgA research paper released late last year investigated this trade-off, attempting to pinpoint how much leisure time is best. Its authors examined the relationship between the amount of “discretionary time” people had—basically, how much time people spend awake and doing what they want—and how pleased they were with their lives. (Some examples of “discretionary” activities were watching TV, socializing, going to the movies, spending time with family, and doing nothing.) The paper, which analyzed data covering about 35,000 Americans, found that employed people’s ratings of their satisfaction with life peaked when they had in the neighborhood of two and a half hours of free time a day. For people who didn’t work, the optimal amount was four hours and 45 minutes. Read the whole story: The Atlantic Up and down the economic ladder, many Americans who work—and especially those raising kids—are pressed for time, wishing they had more of it to devote to leisure activities (or even just sleeping). At the same time, research has indicated that people who are busy tend to be happier than those who are idle, whether their busyness is purposeful or not.last_img read more

Clear stretches across less populated areas hub of speed driving

first_imgKolkata: Straight stretches of national highways which pass through thinly populated areas have become the hotspots for a section of owners of high-end cars and motorbikes for “recreational speed driving” on Sundays. There are a section of people who flout norms even when Bengal has come up as one of the best states in checking road accidents and creating awareness among people with Chief Minister Mamata Banerjee’s statewide campaign of Safe Drive Save Life. Also Read – Heavy rain hits traffic, flightsVivek Sahay, ADG (Traffic and Road Safety), said: “Many people have a wrong notion that there are no speed limits on expressways or highways. It is on that basis that they seek to justify speed driving. But it is not so. There are speed limits for all vehicles.”It may be mentioned that there is a group of people in and around Kolkata who have formed clubs and go out with their high-end expensive cars or two-wheelers for “recreational speed driving,” especially on Sundays. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThere are stretches on National Highway 2 which are straight and pass through thinly populated areas. The stretch mainly falls under the jurisdiction of Jamalpur, Memari, Burdwan and Galsi police stations and is straight where vehicles can be plied at high speed. Another such stretch is at Gurap in Hooghly.Concerned senior police officers have recently visited the spots in this connection. Interestingly, there are around 3,500 cars in Kolkata which cost more than Rs 90 lakh. Some of these cars cross 500 hp in power output and can easily cross 200 km per hour. Police maintain a vigil to avoid over-speeding of vehicles and the number of prosecution cases for the same has also gone up manifold compared to that of the past few years. It is not only the case of high-end vehicles but any vehicle that over speeds comes under the purview of prosecution. Last year only 75 speed cameras were installed in districts to check speeding and it resulted in a major drop in road accidents.last_img read more

Former footballers body found on railway tracks near Lake Gardens

first_imgKolkata: Mystery shrouds the death of a former footballer whose body was found on the railway tracks near Lake Gardens in the Sealdah – Budge Budge section on Friday night.The police are yet to confirm if the victim had committed suicide or there was any foul play behind his death. The victim, Ranjit Chatterjee, used to play football for Calcutta Port Trust but could not continue as poverty played spoilsport and his dream remained unfulfilled. According to the police, the victim went abroad to take training in football. A great lover of the game, Chatterjee had bought an auto-rickshaw around two years ago and used to earn his living by driving the vehicle. But he never de-associated himself with the game and began imparting football training to children of his locality and nearby areas. Also Read – Heavy rain hits traffic, flightsThe family members are in shock. They are yet to believe that a strong character like Chatterjee who had tremendous determination and will-power would throw himself in front of the running train and end his life. A complaint with the local police station has been lodged mentioning the names of some persons who, the family suspects, might have been involved in the death of the former footballer. According to the investigation, the cops came to know that he had left home at around 8.30 pm on Friday after watching the World Cup match between Brazil and Costa Rica. The family members received a phone call saying that his body was found lying near the railway tracks at Lake Gardens station. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe locals also told the police that the victim was never involved in any quarrel with anybody and was a good-natured person. They could not imagine that a man of such character could commit suicide. The police have, however, started a detailed probe on the basis of the complaint lodged by his family members. The investigators also collected samples from the spot to determine the nature of his death. The body has been sent for post-mortem, the result of which might throw light on the footballer’s death.last_img read more

Boredom can make you politically radicalised

first_imgIf you are bored and are unable to find a meaning in what you do, chances are you may develop extreme political views sooner, a study reveals. Boredom may be contributing to a widening of political views among voters, according to researchers from King’s College London and the University of Limerick.“Boredom puts people on edge. It makes them seek engagements that are challenging, exciting, and that offer a sense of purpose. Political ideologies can aid this existential quest,” said Dr Wijnand van Tilburg from King’s College London. Boredom motivates people to alter their situation and fosters the engagement in activities that seem more meaningful than those currently at hand, he added.  Also Read – ‘Playing Jojo was emotionally exhausting’Published in the European Journal of Social Psychology, the findings are based on one experiment and two scientific surveys carried out in the Republic of Ireland.In their initial experiment, the researchers recruited 97 people from a university campus. The participants first indicated their political orientation (whether they considered themselves liberal or conservative) before being randomly assigned to complete either a task deemed to be highly boring or a comparatively less boring task. Also Read – Leslie doing new comedy special with NetflixThose assigned to the high boredom group transcribed 10 references about concrete mixing, while those assigned to the low boredom group only had to transcribe two of these references. After completing the boring tasks, the researchers asked the participants to describe their political orientation once again. However, this time the participants indicated their political orientation on a seven-point scale. The researchers found that liberals in the low boredom group were more moderate in their political orientation, compared to liberals in the high boredom group. A similar trend was found for conservatives, though it was not statistically significant as there were only 26 politically right-wing participants, which reduced the study’s statistical power. The study authors also conducted a survey of 859 people living in Ireland and found that people who were easily bored tended to endorse more extreme political views. Another survey of 300 people found that being prone to boredom was associated with searching for meaning in life, which was in turn associated with political extremism. The authors suggest that adopting a more extreme political ideology is one way that people re-inject meaningfulness into a boring situation.“These studies indicate that political views are, in part, based on boredom and the need to counteract these negative, existential experiences with ideologies that seem to provide meaning in life,” noted Dr Eric Igou from University of Limerick. The implications of these findings are obvious. “Possibly politically radicalised individuals and groups are, at least to some degree, driven by boredom experiences in their everyday lives as an attempt to make life seem more meaningful,” the authors pointed out.last_img read more

Buddha beyond time

first_imgGautam Buddha and his teachings have always played a pivotal role in India and South Asian parts of the world. An ongoing exhibition in New Delhi has marked the importance of His lessons.Hosted by Atul Todi, an ongoing exhibition ‘Finding Buddha’ is being held at the Convention Foyer at Indian Habitat Centre till March 24 in New Delhi, which has brought the sage’s lessons into prominence.”Buddha means the awakened one…someone who has woken up from the sleep of ignorance. This awakening happens with the recognition of one’s source of happiness,” said Todi. Also Read – Add new books to your shelfHe further added that, “For generations, Buddha’s paintings have shown him as a symbol of meditation. They do not imbibe the true message of Buddha or connect with today’s generation”.”It has no fixed time, geographical boundaries or defined monetary value. Buddha can be a moment in the rain or a sip of a freshly brewed coffee. He is in anything that awakens our mind and allows us to be in-tune with our inner self,” Todi said.Putting an emphasis on the importance of peace and stillness, Buddha has been portrayed in different images in varied forms. Each picture depicts Him either as an astronaut, or as playing guitar. He has also been shown on a scooter in of the pictures. Although the images are disparate, but every picture shows him in meditative posture.The exhibition focusses Siddhartha Gautam as a meditator and that he preached meditation to attain ‘Nirvana’ (suffering) to banish all desires from their lives.last_img read more

Guide your feet this monsoon

first_imgOur feet are the most neglected parts of our bodies, even though they are often considered the most important. Yet, our feet can be the most vulnerable because they are exposed to the environment. And, with the monsoon season upon us, foot problems are even more common. Essentially, the moist, wet and humid conditions predispose your feet to more infections and irritations, causing a higher rate of fungal and bacterial infections. Dermatologist Dr Amit Bhasin, will guide your feet this season. Also Read – Add new books to your shelfAvoid wearing closed shoes: By wearing closed shoes, you increase the amount of moisture your feet are exposed to. This then predisposes you to those pesky fungal infections. Instead, wear open toed shoes to keep your feet properly aired out.Dry your shoes: Often, after walking around during monsoons where the ground is wet and puddles abound, your shoes tend to get soggy. Never wear wet shoes! Make sure you dry out your shoes overnight so that they are dry again when you use them. In fact, if you keep them out in the sun, then you will also have the benefit of UV rays killing bacteria. Also Read – Over 2 hours screen time daily will make your kids impulsiveKeep your feet clean: Make sure you wash your feet every day after you come back home. Get that grime and mud off your soles with gentle warm water and a mild soap daily. Then, make sure that your feet are dry before putting on your slippers or socks.Don’t walk barefoot: When walking around at home or at the gym, it’s really easy to leave off your flip-flops. But, when you walk without chappals on wet floors, you can pick up diseases such as warts, which are virally transmitted, or athlete’s foot. So, remember to wear your flip-flops so you don’t get any of those pesky issues.Avoid getting pedicures: Those outside pedicures put you at risk for getting foot infections.last_img read more

How to pair sunglasses with other accessories for a chic look

first_imgWhen done right, eyewear can add a hint of suavity to any outfit but the questions is how to pair your sunglasses with other accessories for a chic look. Experts suggest some smart ways to team it up without creating any fashion faux pas. Here are few tips:Patterned metal-framed sunglasses and cufflinks: Lightweight metal framed sunglasses with patterned detailing are popular these days. Cufflinks are a great way to add a personal touch to an outfit as it is a piece of jewellery along with functional benefits. It helps in displaying one’s unique fashion sense and can simply add that tinge to a basic shirt. As long as it’s a long-sleeved shirt with requisite holes in the cuffs, one can work cufflinks with all kinds of outfits. Also Read – Add new books to your shelfAviators and leather belt: Aviators is a summer staple but they can look great in winters too, especially when supplemented with gloomy outfits for a laid-back look. These can also be paired with a formal and semi-formal outfit for a more sophisticated look. Inclusion of a good textured leather belt can take one’s look to the next level. A belt is, of course, important in keeping one’s pants in place; however, they need not be just functional. It’s a good idea to splurge in tan browns, black and navy blue colour. The best tip would be to match the colour of the belt with the shoes. Also Read – Over 2 hours screen time daily will make your kids impulsiveDark tinted lens sunglasses and tie: They can make you look debonair when complemented with a formal outfit. The dark tinted sunglasses reduce the glare of reflective surfaces which makes them suitable for driving and, therefore, upping their utilitarian quotient too.A tie is an easy way to sharpen up the everyday work wear. It’s a eulogy for being a great add-on to accentuate one’s look. Whether suiting up for the office or laying out a look for the evening, a tie allows one to pull together the incongruous elements of the wardrobe with a touch of texture or complementary colour. Simple square-shaped hipster glasses and wallets: Hipster sunglasses are unconventional and undoubtedly head-turners. These can subtly highlight the geek chic style of a person. This style can also be paired with a bearded face to bring out the adventurous appeal. Instead of going for a mundane one that does its job well, invest in a good wallet that not just houses cards, money and other important things but is also classy and elegant.last_img read more

Lets preserve conserve water

first_imgIt will not be an exaggeration to say that the next war will be over water. A steadily increasing world population, rampant water pollution, and the unchecked exploitation of natural resources have played their role in bringing us to where we stand today. Negligence of customary water bodies like lakes and tanks, abuse of groundwater, and incorrect preservation of surface water systems have added to the growing burden. It is going to grow with every passing second. Hence it is high time that all of us get up from our slumbers and put our act together to do our bit towards water conservation. Also Read – Add new books to your shelfPatton has been proactive in addressing water woes and is coming up with solutions like ‘Rain Water Harvesting’ , ‘Ground Water Recharging’ and introducing ‘Water-On-Wheels / Roller Tank’ in different parts of West Bengal. PATTON – WATER-ON WHEELS/ ROLLER TANK In India, millions of villagers do not have access to safe and clean drinking water. Around one out of every five persons in rural India does not have access to clean drinking water. Also Read – Over 2 hours screen time daily will make your kids impulsiveThere are several natural causes, including arsenic and fluoride in ground water which are adding to the problem. Hence women have to struggle daily for clean water. Water is traditionally carried in heavy 20 litre buckets balanced on their head from collection points located away from their homes.This is a strenuous task causing long-term neck and spinal injuries and equally time consuming requiring multiple trips per day covering three to six hours . Specially designed Patton Water Roller Tank enables to collect large amounts of water, which is almost five times more hygienic than a single bucket, by simply rolling it along the ground reducing drudgery of water collection from far places. The savings in time, energy and reduced suffering are immense and the positive social-impact benefits are far reaching. Patton-Water-On-Wheels is already introduced in districts like Darjeeling, Bankura, Purulia etc. Rain Water Harvesting Rain Water Harvesting is the process of collecting Rain-Water falling on roof-tops in a tank for future productive use. Patton has installed many Rain Water Harvesting Projects in West Bengal where Rain Water is being used as source of drinking water. We are dedicatedly working on ‘Rain Water Harvesting’ and ‘Ground Water Recharging’ in association with different bodies such as Public Health Engineering Darjeeling Gorkha Hill Council, Institute of Environmental Studies and Wetland management, Institution of Public Health Engineers, Forest Department, Many schools in Sundarban, Bonnie Camp Tiger Reserve, Lahiripur Forest Camp, Kalas Tiger Reserve, Sajnekhali Pakhiralaya and Bhagabatpur in Sunderban to name a few. We believe sincerely there is much more to do. Every single drop counts. Let us all preserve and conserve it. Our journey continues…last_img read more

Stingy and Cranky – Ebenezer Scrooge was Inspired by a RealLife British

first_imgHolidays are coming and it’s time for Charles Dickens’ Christmas Carol. It is one of the most beautiful stories ever written, and Ebenezer Scrooge is still a synonym for a grumpy miser, or in modern terms, a greedy and cruel corporatist. Ebenezer Scrooge is perhaps Dickens’ most iconic character. The puzzling part was whether he created Scrooge out of thin air, or if he was inspired by a real-life character. According to research, it’s the latter.Marley’s ghost, from ‘A Christmas Carol. In Prose. Being a Ghost Story of Christmas’ by Charles Dickens. First edition illustration by John Leech. Published by Chapman & Hall, 1843.Legend has it that while in Edinburgh, in 1841, Dickens visited Canongate churchyard where he noticed a gravestone inscribed with “Ebenezer Lennox Scroggie – MEAN MAN”, and perhaps thought how terrible a person could have been to be remembered in such a way.The deceased was, in fact, a “MEAL MAN” or corn merchant — Dickens’ misreading of the mans occupation inspired the name for his character: Mr. Scrooge.Charles Dickens between 1867 and 1868In a 2014 book Inventing Scrooge: The Incredible True Story Behind Dickens’ A Christmas Carol, Carlo DeVito writes how Dickens created the protagonist of the book. Dickens was inspired by the life of John Elwes, today credited as the real-life Scrooge.Elwes, born John Meggot, in 1714, was a Member of Parliament who was known for his miserliness.Elwes the Miser, MP (7 April 1714 – 26 November 1789).His father, Robert Meggot, was a respected London brewer who died when John was only four, and left an inheritance of £100,000, equivalent to a couple of hundred million today. Although wealthy, John’s mother reportedly starved herself to death because she was too mean to spend money on her well-being.John grew up to be a party-going, hedonistic, and generous man, a scholar at Westminster who liked high society and enjoyed riding and traveling abroad.Scrooge extinguishing the first spirit.The main reason he changed his way of living and turned into a miser was his greediness for another inheritance — his uncle’s. Sir Harvey Elwes died in 1763, leaving his estate worth £250,000 (equivalent to $23 million today) to his nephew John, who even changed his name to Elwes to inherit that money.With an eye on the fabulous fortune, John gave up his extravagant rich life to impress his uncle. But after Sir Elwes’ death, instead of enjoying the wealth, John remained unimaginably stingy.He lived in a mansion with many rooms equipped with luxury furniture but during the winter, the young Elwes would spend most of his time in the kitchen with his servants so that he didn’t have to light another fire in the living room.“The Ghost of Christmas Present” from the original edition, 1843.Refusing to pay money for maintenance on his house, water started dripping from every hole in the roof, and the grand furniture fell into a state of a complete decay.He wore ragged clothes everywhere he went, and even slept in them. Sometimes he was mistaken for a beggar and given handouts, much to his joy.His meals consisted of a single hard-boiled egg and a pancake which he kept cold in his pocket. He regularly ate moldy food, and one rumor was that he even ate a rotten moorhen he took from a rat.Elwes with a money bag.The miser wore a tatty wig he found discarded in a hedge, avoided paying coaches even on rainy days, and sat in wet clothes to save the wood for the fire.One story has it that Elwes hurt both of his legs while walking in the dark and allowed an apothecary to treat only one while wagering his fee that the untreated would heal first. He won the bet and refused to pay the doctor.Edward Topham by John Russell, c.1795.Interestingly, according to John Elwes’ friend and biographer, Edward Topham, despite being so incredibly tight with spending on himself, John’s generosity was renowned: “…his public character lives after him pure and without stain. In private life, he was chiefly an enemy to himself.”He was elected as a Member of Parliament for Berkshire in 1772 and remained at the position for 12 years. He paid a whopping 18 pence in election expenses, and after three mandates he retired because he didn’t want to spend money on being re-elected.Marcham Park, formerly in Berkshire, from the north east. Photo by Rodolph CC By SA 3.0Whenever he traveled to London for his job, Elwes rode a horse rather than ride in a carriage to avoid spending money on expensive turnpike tolls.On the other hand, he was always quick to lend money and never asked for repayment, deeming asking for such things below a gentleman.He also made a lot of investments and financed many building developments in London, some of which remain today such as Piccadilly, Portman Square, and the famous Baker Street.As Topham wrote: “To others, he lent much; to himself, he denied everything. But in the pursuit of his property, or in the recovery of it, I have it not in my remembrance one unkind thing that ever was done by him.”Read another story from us: Charles Dickens’ Pet Raven Inspired Edgar Allen Poe’s Most Famous WorkJohn Elwes immersed himself in full-time miserliness. On his death in 1789, he left £500,000 (almost £1bn today) to his two illegitimate sons.last_img read more

Clevelands deadline deals separated them from Boston in the East

first_imgCleveland’s deadline deals separated them from Boston in the EastThe Cavs overhauled most of their roster with a slew of deadline deals in which they acquired George Hill, Rodney Hood in a three-team deal with the Kings and Jazz, and Jordan Clarkson and Larry Nance, Jr. from the Lakers for malcontent Isaiah Thomas.In their debut against Boston, a re-energized LeBron and his new squad manhandled the Kyrie Irving and the Celtics on Paul Pierce’s jersey retirement ceremony day, and Colin thinks the deadline roster reformation has ended any hope that Boston can win the East this season.“Cleveland separated from Boston and Cleveland absolutely closed the gap on Golden State.” The Patriots are fun to play for because constantly winning is funEagles offensive lineman Lane Johnson called the Patriots a ‘fear based organization’ in a post Super Bowl interview and described the New England players as robotic.  Johnson said he would rather win one Super Bowl with the personality driven Eagles than five with the stiff Patriots.Colin thinks Johnson is off base because even though the Patriots are more buttoned up than Philly, the main goal in professional sports is to win, and no one has won more consistently than the NFL than the Patriots. Colin thinks it sounds like a blast.“Football is fun when you’re winning. Nobody wins more and more consistently than Gronk, Brady, Belichick and the Patriots.” Also:-Why the Niners are Colin’s Super Bowl dark horse pick in the NFCGuests:Doug Gottlieb – FS1 Analyst and host of The Doug Gottlieb show is in-studio talking new look Cavs first game; and why the Niners did more than test drive Jimmy G;Chris Long – Eagles Defensive End is in-studio discussing the different approaches in New England and Philly; the challenges of growing up as the son of a Hall of Famer; and what he saw from Jimmy G in his year with New England.Chris Broussard – FS1 NBA Analyst is in-studio talking Cavs deadline moves and if they can allow the Cavs to compete with Golden State.last_img read more

No, it’s a tablet. Wait, it’s a smartphone that’s so large it looks like a tablet.2. emojiKnow all those annoying, overly emotional animated faces your friends text and message in their communications to you?

New Breed of Products Aims to Improve Users Lives

first_img Growing a business sometimes requires thinking outside the box. 4 min read April 8, 2014 Opinions expressed by Entrepreneur contributors are their own. Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now » Great products are now becoming part of a richer experience that defines who we are. As such, entrepreneurs must stop putting such a narrow focus on product design and ask themselves a simple question: How can I improve people’s lives? This is the dawn of a new era — one in which we don’t create products and services for users, but create products that are in service of people’s lives.Related: When Your Product Design Makes Your Customers Feel SmartThis new breed of products is solving human needs not by asking people to do or consume more, but by taking away cumbersome tasks, responsibilities, buttons and activities. We have seen (and feared) this change in industry throughout the ages, where machines and software took on the roles of manual workers. But in the world outside manufacturing, removing the burden of yesterday’s technology can help someone get more out of their life without the negative impact.A few exemplars are emerging in this new era of life enhancers. Companies such as Nest, Jawbone and Google are creating products that truly serve the people who integrate them into their lives. These companies are approaching product design not just by identifying a user need (and creating a product to solve it) but by asking the question, “how can we make people’s lives better?” Their answer: Not optimizing a task through technology but changing our relationship with what technology can do for us.What’s special about these companies is that they know their story and they bring it to life through the products they create. They have something they want to see come true in the world. It transcends — but doesn’t eliminate — the identification of a user need or pain point that most design processes focus on. Knowing your story can lead to products that have a larger and longer impact on people’s lives.Related: The Ultimate Test: Turning Your Cool Idea Into a Great ProductFor example, Nest is not simply a digital version of a thermostat that lets you adjust your room temperature with a delightful interface or smartphone. It is a product that comes from a company with a quest to make you comfortable and safe. Their products remove the need for you to manage and adjust, or be concerned about cost and the impact energy consumption has on the environment.Jawbone Up is a cool way to track your steps, but it’s also a partner to make you a healthier, more balanced and ultimately a happier person. It solves a problem — it makes keeping track of your fitness and health much easier — allowing you to seamlessly integrate good health into your everyday life.Google Loon, a network of balloons that provides internet access to people in remote areas, takes its story to another level when it comes to scale and technological ambition. Loon’s quest to give access to everyone on Earth is exemplified through its product, making Google’s story of organizing the world’s information and making it universally accessible a reality.Products such as these create a new kind of relationship with their consumers. It’s no longer the new feature, the latest upgrade or the shinier edition that matter. It’s the positive impact it has on their lives outside the product itself. That’s the story people want to talk about and share with their friends.Related: The Secret to Successful Product Design? Simplicity.last_img read more
