Californians bask in solar energy Citation: Solar Home Built by Students (2009, September 22) retrieved 18 August 2019 from https://phys.org/news/2009-09-solar-home-built-students.html Explore further Curio House. Image from livecurio.us The solar home will be dismantled and reassembled on the National Mall in Washington, D.C., early next month, where it will be subjected to 10 days of judging. The student-designed home will be open to the public, and will be judged on factors such as attractiveness of the design, marketing viability, energy efficiency, and the amount of excess electricity the home generates.The budget for the New England team’s design for the 800 square foot one-story home came in at around $200,000, and they hope the sale price could be about the same figure, but for a reduced number of solar panels. The sale price would make the design far more marketable than the 2007 competition design by a German team, which would sell for $1.2 million. The Boston students worked for nearly two years on the project. They reduced costs by purchasing widely available products from building supply stores, and by using a simple, modular design that could be constructed easily. The most expensive items were the bank of 28 top range SunPower photovoltaic panels and five solar thermal panels to heat the home and supply hot water. Tufts student Matt Thoms, who served as project director for the Curio House engineering and photovoltaics, said the team wanted to build a house that could be available now, and not something that would not be available on the market for five to ten years. The students also wanted to design a house that would be suitable for city and urban living, and not just for people in rural areas living off the grid. With this in mind, the house is designed for a couple with a small child, and it includes screens for the front deck and back porch that would provide privacy. The house has technologies expected in today’s city homes, such as Ethernet, but it also has a small garden watered by captured storm water to encourage the occupants to grow some of their own food and live a more sustainable lifestyle. The photovoltaic panels supply 6.4 kW, which is more than a home of the same size would need if connected to the grid, but for the competition the home must run for 10 days off the grid. A number of jobs must be completed, such as a movie night featuring the home’s entertainment system, and washing 10 loads of laundry during the period. Batteries fed by the solar panels produce night time and cloudy day electricity supplies for the home.The Curio House is well insulated to reduce heating and cooling needs, and is fitted with energy-efficient appliances and lights. It also has outdoor blinds on the southern side that can be adjusted to allow sunlight in for warmth and light. As a result of these features the students expect the electricity use to be around one third that of a typical American home of the same size.The students focused on designing a home that is affordable enough for people to live in now, and they have already found a buyer, since the building will become the first home in a “green community” planned for Cape Cod. The design can also be adapted for larger homes or apartments.The Solar Decathlon is held every two years and is run by the U.S. Department of Energy.More information: www.livecurio.us/© 2009 PhysOrg.com (PhysOrg.com) — Students from the Boston Architectural College (BAC) and Tufts University have submitted a completely solar-powered home, the Curio House, as New England’s entry into the Solar Decathlon competition. The entry is one of 20 designs by teams of university students vying for this year’s award for the best solar home design. This document is subject to copyright.

(Phys.org) — You may have had to think about the Internet as a place where your Web usage puts a pricetag on your head and you are treated with ads assuming you are a likely customer. Now you need to think about the Internet as a place where your Web usage may land you on the books as mentally imbalanced. Sriram Chellappan and Raghavendra Kotikalapudi are two researchers who suggest the way one uses the Internet says something about the user’s mental well-being. Chellappan is an assistant professor of computer science at Missouri University of Science and Technology and Kotikalapudi is a computer science graduate. © 2012 Phys.Org They studied results from 216 undergraduates at Missouri S&T. The participants had to fill out a version of the Center for Epidemiologic Studies Depression Scale questionnaire, used for measuring depression levels in the general population. The survey revealed that 30 percent of the participants met the criteria for depressive symptoms. This, said the authors, is in line with national estimates that 10 to 40 percent of college students at some point experience such symptoms. The school’s IT department gave researchers campus data on campus Internet usage data for the participants—information about traffic flow that the university customarily collects for troubleshooting network connections. The authors say that this is one of the study strengths. “Earlier studies have looked into the relationship between Internet usage and depression, but ours is thought to be the first to use actual Internet data, collected anonymously and unobtrusively, rather than student-completed surveys about Internet usage, which are less reliable.”The researchers applied that data for a statistical analysis of the depression scores and Internet usage data. They said they found that students who showed signs of depression tended to use the Internet differently from those who showed no symptoms of depression.Several telling signs of depression, according to the study, could be correlated to features of Internet usage, as “p2p packets, which indicate high levels of sharing files (like movies and music).” Another sign they claimed was a sign of depressive people was very high e-mail usage. They shared the view with some psychologists that frequent checking of e-mail may relate to high levels of anxiety, which they said correlates with depressive symptoms. The authors also called out high “flow duration entropy, ” which they said often occurs when there is frequent switching among Internet applications such as e-mail, chat rooms and games.Other characteristic features of “depressive” Internet behavior, according to the study, included increased amounts of video watching, gaming and chatting.The authors suggest practical applications of their research could be a software application for use on home computers and mobile devices. It would monitor Internet usage and alert the person when usage patterns may signal depression symptoms.They also suggested the app as a tool for parents to monitor mood-related Internet usage patterns of their children. A third suggestion is that the app be used at universities to notify counselors of students whose Internet usage patterns indicate depressive behavior. A paper describing the research, “Associating Depressive Symptoms in College Students with Internet Usage Using Real Internet Data,” has been accepted for publication in a forthcoming issue of IEEE Technology and Society Magazine..

gigaom.com/cloud/intel-immerse … il-and-they-like-it/www.grcooling.com/ (Phys.org)—Intel just finished a yearlong test of Green Revolution Cooling’s mineral-oil server-immersion technology. Intel has tried immersing servers in the company’s oil formulation to keep the servers cool and they report good results. The Intel servers were subjected to a yearlong bath in boxes filled with the oil-based coolant. Intel’s results are one more way for the Austin, Texas-based company to pass along a convincing message that dipping a data center’s servers in oil is not crazy but a sane way to cool the data center’s power-hungry machines. The company believes its liquid cooling enclosures can cool high-density server installations at less cost. “We can reduce cooling energy use by 90 to 95 percent while also reducing server power by 10 to 20 percent,” according to the company. HP picks Intel’s Centerton for low-power server rollout Supermicro SuperServers submerged at CGGVeritas Citation: Intel does math on oil-dunk test for cooler servers (2012, September 3) retrieved 18 August 2019 from https://phys.org/news/2012-09-intel-math-oil-dunk-cooler-servers.html Explore further Patterson said that the company found the technology to be safe for its server components. At the end of the test period, the Intel servers were placed in its failure-analysis lab, which did not find any damaging effects.Green Revolution Cooling’s product is called the CarnotJet System, defined as a fluid submersion cooling solution for data center servers. It uses nonconductive liquid coolant rather than air to achieve maximum cooling efficiency and performance.Mention “oil” and add “servers immersed in oil” and for those not familiar with the results, this can sound very strange if not risky, Intel’s Patterson said. That initial reaction is worth getting past. Patterson said Intel’s research into how to build oil-optimized servers could result in a reference architecture around which server manufacturers could begin building such systems.Already, Green Revolution Cooling has a list of customer centers running computer systems that make use of the approach. These include the Oil/Gas Seismic Processing Center; European Colocation Center; East Coast Corporate Data Center; US Research Institute; and the Texas Advanced Computing Center.The coolant is clear, has a light viscosity, is odorless and is nontoxic. The company calls its coolant GreenDEF, which is a formulation of nonconductive white mineral oil. Their formulation is optimized for cooling servers and other data center hardware. More information: Intel reports that the servers ran at a PUE just above 1.0, and showed no damage. Translation: Traditional air-cooled server racks often operate at a Power Usage Effectiveness rating of about 1.6. Intel’s oil-immersed servers operated at a PUE between 1.02 and 1.03, according to Mike Patterson, senior power and thermal architect at Intel.Patterson said the oil-dunking approach is now in Intel’s evaluation phase. Intel will need to understand the fuller implications of oil-optimized platforms. Potentially, the approach may reduce the cost of running data centers, as cooling through the oil immersion system can bring reductions in average and peak power consumption. Those taking their first leap to use this oil immersion approach would be those who want as much power as possible coming out of their computing operations with as little as possible applied toward cooling. When compared to present-day design principles for keeping servers cool, the oil-immersion approach could have far-reaching effects. That is what Patterson means by its having an impact on a reference architecture around which server manufacturers can build their systems. Oil immersion would do away with the need for raised floors and other requirements for air cooling. According to Green Revolution Cooling, energy is saved by removing server and power supply fans from the servers, as they are no longer necessary when servers are submerged. The company also touts the advantage of server reliability, as the servers do not collect dust. Dust is a thermal insulator that raises server temperatures and reduces reliability. One recent study, they said, showed that dust accumulation increased power draw by 2 percent due to server temperature increases. The circulation of the coolant is said to be “excellent” with uniform temperatures without hot spots. © 2012 Phys.org This document is subject to copyright.

Researchers discover way to allow 80 percent of sound to pass through walls More information: Air transparent soundproof window, arXiv:1307.0301 [cond-mat.mtrl-sci] arxiv.org/abs/1307.0301AbstractA soundproof window or wall which is transparent to airflow is presented. The design is based on two wave theories of diffraction and acoustic metamaterials. It consists of a three-dimensional array of strong diffraction-type resonators with many holes centered at each individual resonator. The acoustic performance levels of two soundproof windows with air holes of $20mm$ and $50mm$ diameters were measured. Sound waves of 80dB in the frequency range of $400 – 5,000Hz$ were applied to the windows. It was observed that the sound level was reduced by about $30 – 35$dB in the above frequency range with the $20mm$ window and by about $20 – 35$dB in the frequency range of $700 – 2,200Hz$ with the $50mm$ window. It is an extraordinary acoustic anti-transmission. The geometric factors which produced the effective negative modulus were obtained.Found on Arxiv Blog This document is subject to copyright.

Explore further To prevent noise from passing from one place to another, engineers generally use types of material that are able to transfer sound in the air to another medium, which then weakens its force (attenuation). For that reason, it would seem impossible to create a medium that would allow sound carrying air to pass though, while muting the very sound its carrying. But that’s what the team in Korea has accomplished.The window, is not actually a window, instead it’s two parallel planes of clear plastic separated from one another by a mere 40 millimeters—similar to double paned glass. The chamber between the plastic planes has been designed in such a way as to ensure that sound that enters is counteracted by the pressure in the chamber—using a principle known as bulk modulus (a materials’ resistance to compression.) Each chamber is “roughly” 150 millimeters square—to create a larger window the chambers were arranged in an array. The double pane approach muted sound, but not nearly as much as most would like. To cause more muting the team placed cylinders made of clear plastic through the planes (which they call emitters and receivers)—each with a piece of flat clear plastic covering both ends. A hole was then drilled through the flat plastic pieces allowing sound carrying air to pass through. As it did so, the sound was diffracted into the chamber between the two planes. The reason a cylinder was used instead of just drilling a hole in the plane was for allowing a filter to be placed to prevent the air passing through from whistling. The result is a window, or venting system, that allows for air passage while muting sound. Testing of the window showed it able to reduce sound by 20 to 30 decibels.The researchers note that changing the size of the hole allows for muting different frequencies. This they say could lead to interesting scenarios, such as a venting system that would mute annoying noises while allowing desired noise (such as waves on a beach) through along with fresh air. (Phys.org) —A team of materials scientists in South Korea has created a type of window that mutes noise while simultaneously allowing air to move through. In their paper they’ve uploaded to the preprint server arXiv, the team describes their window and how it was constructed.

(Phys.org)—A team of researchers with members from several institutions in Germany has found that the female burying beetle gives off a pheromone during parental care that causes male beetles to temper their sexual advances. In their paper published in the journal Nature Communications, the team describes their study of hundreds of the beetles captured in a German forest and brought to their lab. A burying beetle mother feeding one of her offspring on a mouse carcass. Credit: Heiko Bellmann. Burying beetles lay their eggs in dead animal carcasses—when the young hatch, the mother, and to some extent, the father take bites from the carcass, chew it, and then feed it to the young. They also both fend off predators. Prior research had shown that during this time period the female emits a gas of some sort, and that there was less sexual activity than normal. In this new effort, the researchers sought to learn the properties of the gas and to determine if it was responsible for the decrease in sexual activity, which in turn led to better care for the young. To find out, the team captured approximately 400 of the beetles, split them into groups of those with offspring, and those without, and then ran several experiments and tests on them.One of the tests involved measuring hormone levels in the females—in so doing, the researchers found that one called ‘juvenile hormone III’ increased, causing the female to be less fertile during the time she was caring for her young. They also found that she emitted a similar chemical called methyl generate, a pheromone, during the same time frame. Next the team ran several experiments to determine if it was the pheromone that caused the antiaphrodisiac-type effect in males—one of which involved monitoring the release levels of the pheromone and the sexual activity of males when the young were removed from both parents, preventing parental care. They found that the production and emission of the hormone did indeed suppress sexual advances by males, which allowed both to better parent their offspring.

A hormone-related female anti-aphrodisiac signals temporary infertility and causes sexual abstinence to synchronize parental care, Nature Communications (2016). DOI: 10.1038/ncomms11035AbstractThe high energetic demand of parental care requires parents to direct their resources towards the support of existing offspring rather than investing into the production of additional young. However, how such a resource flow is channelled appropriately is poorly understood. In this study, we provide the first comprehensive analysis of the physiological mechanisms coordinating parental and mating effort in an insect exhibiting biparental care. We show a hormone-mediated infertility in female burying beetles during the time the current offspring is needy and report that this temporary infertility is communicated via a pheromone to the male partner, where it inhibits copulation. A shared pathway of hormone and pheromone system ensures the reliability of the anti-aphrodisiac. Female infertility and male sexual abstinence provide for the concerted investment of parental resources into the existing developing young. Our study thus contributes to our deeper understanding of the mechanisms underlying adaptive parental decisions.

Kolkata: The job fair organised by the Directorate of Employment under the state Labour department, has provided employment to 602 youths in the state. The appointment letters were handed over by state Labour minister Moloy Ghatak on Monday, at a programme held in Khudiram Anushilan Kendra.”We had roped in some leading companies for the job fair on September 4, where the job seekers came in direct interface with the employers. As many as 23 employers from sectors like transport, insurance, education etc. attended the job fair at this venue itself and interacted with the candidates. After conducting all interview formalities they have selected 602 candidates,” state Labour minister Moloy Ghatak said.Elaborating on the initiatives of the Employment Directorate for ensuring employment of youths in the state, Ghatak said his department has come up with 10 skill development centres for jute workers in various parts of the state.”We are providing training to youths on spinning and weaving of jute. A person who has passed the eighth standard is eligible for the training, which three months in duration. In the first month of basic training, the candidate gets a stipend of Rs 180 per day and in the second and third month, when they do practical training in jute mills, they get a stipend of Rs 250 per day. Following this training, they are employed by the jute mill itself,” the minister said. The employment is guaranteed as the jute mills have an agreement with the directorate in this regard.Amarnath Mallick, the secretary of the Labour department, said that the department will hold more such job fairs and will rope in IT, marketing and sales companies to participate.

We are trying to collect the CCTV footage to track the culprit,” he added.
Ever wondered what causes your shoelaces to loosen even when you tie them as firmly as possible? It is because while running, the force of a foot striking the ground stretches and then relaxes the knot, a study has showed. As the knot loosens, a second force caused by the swinging leg acts on the ends of the laces, like an invisible hand, which rapidly leads to a failure of the knot in as few as two strides after inertia acts on the laces.The findings, published in the journal Proceedings of the Royal Society, may help understand things like DNA that fail under dynamic forces, the researchers said. Also Read – Add new books to your shelf”When you talk about knotted structures, if you can start to understand the shoelace, then you can apply it to other things, like DNA or microstructures, that fail under dynamic forces,” said Christopher Daily-Diamond, graduate student at the University of California-Berkeley.Using a slow-motion camera and a series of experiments, the researchers assessed a pair of running shoes that were laced-up and were on a treadmill. They found that shoelace knot failure happens in a matter of seconds, triggered by a complex interaction of forces, as when running, the foot strikes the ground at seven times the force of gravity. Also Read – Over 2 hours screen time daily will make your kids impulsiveIn addition, the study showed that some laces might be better than others for tying knots, but the fundamental mechanics causing them to fail is the same.”The interesting thing about this mechanism is that your laces can be fine for a really long time, and it’s not until you get one little bit of motion to cause loosening that starts this avalanche effect leading to knot failure,” said Christine Gregg, graduate student at the University of California-Berkeley.
Avoid chances of acidity during the hot days by indulging in bananas, melons and coconut water, say experts.Bananas: It is the best antidote for acid reflux and is great for snacking purposes. Potassium in bananas produces mucous in the lining of the stomach, thus lowering the pH levels in the body. Also, bananas are high on fibre and a great source of roughage. Eating over-ripe bananas during summer is the best way to keep acidity at bay.Melons: Melons such as cantaloupe, musk melon and watermelon are high on anti-oxidants and fibre, and help avoid acid reflux and other stomach ailments by maintaining the mucous membrane. The cooling properties and high water content in these fruits help hydrate the body and reduce pH levels. Other fruits such as apple and papaya are also great sources of fibre and aid in preventing acidity. Also Read – Add new books to your shelfCoconut water: This refreshing natural drink has cleansing properties that help flush out toxins from your body. Coconut water is also rich in fibre content and helps with regular bowel movements.Cold milk: Milk is another excellent way to combat acidity. Milk absorbs acid formation in the stomach, stopping any reflux or burning sensation in the gastric system. Anytime you feel an acid formation in the stomach or heartburn coming on, have a glass of plain cold milk without any additives or sugar. Also Read – Over 2 hours screen time daily will make your kids impulsiveButtermilk and curd: Besides milk, other milk products (except cheese) like curd and buttermilk also provide relief from acidity. These products cool the stomach and the natural bacteria in them do not allow acid formation. They help in keeping the overall digestive system healthy. Having curd and buttermilk regularly after meals is a great way to avoid chances of acidity in the long run too.Say no to food carts: Though these should be avoided all year round, they are definitely a strict no-no during summer season. Rise in temperature goes hand-in-hand with water scarcity, which in turn means compromise on washing properly in the kitchen. And that can have a bad effect on your system when you eat food that is not washed properly before cooking or cooked by hands that have been not thoroughly cleaned. Gastroenteritis, amoebic dysentery and diarrhoea are common during this time of the year.Swap juice for whole fruit instead: In summer, you often spot house flies especially in markets near food vendors. They are major germ carriers and thus, people should be careful when having juice outside. Instead of cutting fruits or blending them into juice you should rather try to eat whole fruits to keep infections at bay.
Kolkata: Thousands of devotees visited Belur Math on Friday to celebrate the 184th birth anniversary of Sri Ramakrishna.Special puja was held at the Math. The birth anniversary was observed in all the centres of Ramakrishna Math and mission throughout the country and abroad. In Kamarpukur, the birthplace of Sri Ramakrishna, the devotees visited the temple and took part in the celebration. There were special launch and bus services to ferry passengers to Belur Math.

Rakamrishna Math and Mission authorities have decided to scrap the age-old fireworks display on March 17 at the public celebration as a part of the drive against environmental pollution. There will be cultural programme in the evening. Life of Sri Ramakrishna is an inspiration for scholars and common people and it continues to inspire scholars all over the world. Two noble laureates, Rabindranath and Romian Rolland, had also written about Sri Ramakrishna. Tagore had shared a dais with Sri Ramakrishna and had delivered a lecture during his birth centenary in 1936. Scholars such as Keshab Chandra Sen, Shivnath Shastri, Brojendranath Sil had visited Sri Ramakrishna and were enthralled by his words. His presence of mind, sharp sense of humour and deep understanding of society had made him a popular figure in Kolkata. He also inspired Girish Chandra Ghose, father of Bengal stage to carry on with his vocation. Modern scholars feel that Sri Ramakrishna’s views on universal religion can help to resolve the crisis of the modern world.
The Potter heads among us will surely remember the magical words of Dumbledore when he says, ‘Words are, in my not so humble opinion, our most inexhaustible source of magic, capable of both inflicting injury and remedying it.’ The play ‘Arthur’ delves upon this issue of non-communication through the lens of otherisation of a Northeast Indian youth in the city of Delhi, which they always claim is of ‘Dilwalon’ ki, but rarely one gets to see its caring nature. Also Read – Add new books to your shelfHeld on December 20, 6 pm, at Muktadhara Auditorium, New Delhi, the play was presented by the enthusiastic students from an NGO. After taking workshops for almost a year, this play was the first opportunity for them to showcase their learnings and talent. Coming back to the plot – like most of us, it is much more difficult for the reticent and introvert protagonist Arthur to feel the warmth of Delhi. But is the fault only of the city, or its dwellers? Or is there an interplay of multiple issues that are normally brushed under the carpet, but however need to be confronted, and dealt with? The answers are multifold, and the play tries to deal with these uncomfortable questions and answers. It is the first time that writer and director Janani Ray dealt with an issue which perhaps is close to her heart. Accompanied by a motley group of youngsters, whom she helps provide basic computer and English classes through her NGO AICURD, Ray enthralled the audience in the Capital with the capitavating performance and story.

Concerns have been growing around on some of the last indigenous tribes out there, such as the Sentinelese people who live on the North Sentinel Island off the coast of India. Can these tribesmen, who do not comprise a population greater than 100 men and women, survive in a world that is ever more interlinked and globalized? Is outsiders trespassing their ancestral lands justifiable? Messages sent by the Sentinelese in the past have been loud and clear. They do not wish for communication with the outside world. Past expeditions have proven times and time again that the people from this tribe are not so excited about connecting with strangers. Their usual response to anyone trying to leave footsteps on their small island in the eastern Indian Ocean has been bows and arrows.Members of an unspecified Andaman tribe fishing c. 1870However, in a rare instance during the 1990s, the Sentinelese have responded well to “gift-dropping.” That is a method used by anthropologists to pacify aboriginal tribes and has notably worked well with ancient inhabitants of the Amazon before.The somewhat successful missions were led by the Anthropological Survey of India (AnSI), in which the Sentinelese accepted coconut gifts and even appeared in front of their uninvited guests without weapons.There was also a woman anthropologist on board these missions, in fact, the first woman to ever have an opportunity to see and communicate with the Sentinelese.North Sentinel Island (India) Photo by CC BY-SA 3.0It was January 1991 when Madhumala Chattopadhyay joined the expedition team to North Sentinel. At the time she was doing her Ph.D. with AnSI.To enter the expedition, Chattopadhyay had to provide officials with written consent that she or her family would “not claim compensation from the government for any injury or loss of life,” she told the National Geographic in December 2018.Chattopadhyay, who today works in the Indian government, came on board those 1990s missions after several years of extensively studying the tribes that inhabit the Andaman and Nicobar islands, among which the Sentinelese have remained most resilient to outside contact. She also knew some words of their language.She and her team had been anxious before going to the island. A previous expedition in 1990 did not go so well, as anthropologists were met with the usual dosage of Sentinelese hostility.2009 NASA image of North Sentinel IslandHowever, her group was willing to give it another try. After approaching the island with a small vessel, and after being noticed by the Sentinelese, the team began presenting them with coconuts which they sent floating on the waves. The men guarding the shores were well armed, but also curious.“To our surprise some of the Sentinelese came into the water to collect the coconuts,” said Chattopadhyay who was asked by the National Geographic to recall the mission almost three decades later. Amid a resurgence of interest in the Sentinelese following the death of U.S. missionary John Allen Chau, whose attempt to establish contact with them in November 2018 ended fatally, Chattopadhyay has accepted the invitation to speak about her own experience.Photo by John ChauShe said that when the Sentinelese men saw the coconuts in the water, a type of good not available on their lands, they began wading out to reach for them. Women and youngsters stood on the side and watched the scene. But even in those peaceful instances, danger was present.“A young man aged about 19 or 20 stood along with a woman on the beach. He suddenly raised his bow. I called out to them, to come and collect the coconuts using tribal words I had picked up while working with the other tribes in the region,” Chattopadhyay told National Geographic.“The woman gave the boy a nudge and his arrow fell to the water. At the woman’s urging, he too came into the water and started picking coconuts,” she described the scene.Photo by Madhumala Chattopadhyay“Later some of the tribesmen came and touched the boat. The gesture, we felt, indicated that they were not scared of us now,” she said.This would be as far as things will go. The Sentinelese would not give gifts in return to the visitors nor invite them to show where and how they live. The January 1991 mission concludes here.A few weeks later, Chattopadhyay and her colleagues would return to Sentinel Island once again. Now the group was even bigger and as they were getting nearer to the shore, the Sentinelese showed up, strangely enough, without carrying any weapons.fresh coconuts on blue background,healthy food conceptAccording to Chattopadhyay, on this follow-up visit, the tribesmen climbed in their boat and took a full pack of coconuts. “They even tried to take the rifle belonging to the police, mistaking it to be a piece of metal,” she said.But things quickly took a downturn when one of Chattopadhyay’s colleagues attempted to obtain an ornament of leaves from one of the Sentinelese men. The gesture only invoked hostility. The anthropologists were made to leave instantaneously.Chattopadhyay returned to the island once again after that, but this third round was not helped by the weather and no aboriginal people showed up on the shores. After this trip, decisions at a higher level were brought that expeditions to North Sentinel Island should come at a halt.Photo by © Indian Coastguard/SurvivalOne of the major fears remains that any contact with the Sentinelese risks passing on pathogens carried by outsiders to which they do not have any immunity.During the 19th century, neighboring tribes inhabiting the archipelago faced a dramatic decline in populations following contact and outbreak of diseases such as measles. In this context, the hostility that the Sentinelese express when meeting someone foreign to them is nothing but a strategy to survive.It is best that they are “left alone” advises Chattopadhyay in her conclusion for the National Geographic interview.Read another story from us: Last of her Tribe – The Woman who Spent 18 Years Alone on a Deserted IslandOthers have also expressed a worry that the Sentinelese are currently undergoing a trauma, and that any further contact with them at this point, such as going to their island to find and collect the remains of missionary John Chau, may only worsen the situation and threaten their very existence.
As the draft approaches, more teams are rumored to be looking to move up to snag a QB, and the Giants trading Jason Pierre Paul sends a signal that they are open for business with the second overall pick. Colin’s Mock Draft 5.0 reflects how the impending run on quarterbacks will shake up the Top 10:Browns: Sam Darnold, QB, USC – Darnold aced his pro day in unexpectedly rainy SoCal conditions, and locked up the #1 pick in the process. Colin has said all along that Darnold is his top QB in the draft. He’s the only pick for the Browns here.(1.0, 2.0, 3.0, 4.0 – Sam Darnold, QB, USC)Non mais quelle fin de match ! QB Sam Darnold pour WR Deontay Burnett. TD Trojans !USC 24, Texas 17 OTpic.twitter.com/R1jDYdnOhe— TBP College Football (@thebluepennant) September 17, 2017 3. Jets (From Colts): Josh Allen, QB, Wyoming – Colin had the Bills trading up with the Niners into the 9 slot to grab Allen in previous mocks, but the QB frenzy has the Jets grabbing him after trading up to 3. Allen has by far the best physical tools of any QB in the draft, and his body type and huge arm are a perfect fit for the nasty second half AFC East weather conditions. He’ll need to sit for a year, but Teddy Bridgewater and/or Josh McCown can bridge the gap. Allen is boom or bust, but the Jets shoot their shot.(Colts: 1.0 – Saquon Barkley, RB, Penn State) (Colts: 2.0 – Bradley Chubb, DE, N.C. State) (3.0, 4.0 – Josh Rosen, QB, UCLA)Amazing stuff from Josh Allen at the NFL Combine. Has looked the best out of the first group. Baker, Rudolph and Rosen are in the second group. pic.twitter.com/sjxQbHeEor— Buffalo Sports Talk (@BUFSportsTalk) March 3, 2018 4. Browns (From Houston): Saquon Barkley, RB, Penn State – The biggest home run hitter in the draft falls to the Browns after the Jets and Cardinals go QB. Colin doesn’t think Barkley is a 20+ carry-a-game NFL back, but he’s dynamic and gives the Browns another offensive cornerstone to go with Darnold. It’s a good day in Cleveland.(1.0, 2.0 – Minkah Fitzpatrick, DB, Alabama) (3.0 – Quenton Nelson, OG, Notre Dame) (4.0 – Denzel Ward, CB, Ohio State) 6. Colts (From Jets) : Denzel Ward, DB, Ohio State – GM Chris Ballard starts to reshape a listless defense with the draft’s best corner in Ward. He ran a 4.32 40-yard dash at the combine and his stock is rising as fast as any of this year’s prospects. He’s also a sure tackler. The Colts have so many holes on their roster, a number of picks would make sense here. Ward fills a huge need and get picks by trading down. Win, win.(1.0 – Bradley Chubb, DE, N.C. State) (2.0, 3.0 – Calvin Ridley, WR, Alabama) (4.0 – Quenton Nelson, OL, Notre Dame)Does Denzel Ward get docked for doing this? pic.twitter.com/MwXUEY6Fk7— Marcus Chai (@OaklandScout) February 1, 2018 9. Bills (From Niners): Baker Mayfield, QB, Oklahoma – With the other top quarterback prospects off the board, Buffalo trades into the Niners slot to grab Baker Mayfield. Colin has been critical of Mayfield for maturity issues, but he’s accurate and is one of three rookie QB’s that can play right away. Colin thinks Mayfield’s lack of size and arm strength are a bad fit for the winter conditions in Buffalo.(1.0 – Niners: Denzel Ward, CB, Ohio State) (2.0, 3.0, 4.0 – Josh Allen – QB, Wyoming)Showing off the arm!! @bakermayfield feeling good throwing deep balls to his guys on @OU_Football Pro Day #Sooners #proday #OUDNA pic.twitter.com/Y7S4NxDdmf— Sooner Sports TV (@SoonerSportsTV) March 14, 2018 10. Raiders: Marcus Davenport, DE, Texas-San Antonio – He’s a relatively unknown pass rusher with limitless athletic ability, and Jon Gruden needs defensive help. Davenport may not have the big school pedigree, but made his presence known by dominating the competition at the Senior Bowl. Khalil Mack and Davenport would make a formidable pass rush combo.(1.0, 2.0, 4.0- Marcus Davenport, DE, Texas San-Antonio) (3.0 Roquon Smith, LB, Georgia)Wanna see some hands and nuanced footwork, check out Marcus Davenport here. Makes it seem like such an easy sack, but if you watch how well he sets up the tackle you see why pic.twitter.com/0wO8LbDvD9— Coach Coker (@filmstudybuddy) February 6, 2018 5. Broncos: Bradley Chubb, DE, N.C. State – John Elway may have considered a quarterback if one falls to him, but that ship has sailed. Instead, he goes best available player with explosive pass rusher Chubb. The Broncos D has been on a slow decline since winning the Super Bowl and Chubb would help reignite the pass rush opposite Von Miller.(1.0 – Calvin Ridley, WR, Alabama) (2.0 – Josh Rosen, QB, UCLA) (3.0, 4.0 – Bradley Chubb, DE, N.C.

Cardinals (From Giants): Josh Rosen, QB, UCLA – Colin’s last mock had Rosen to the Jets with the third selection, but Arizona GM Steve Keim needs a QB so he jumps in front by working a deal with the Giants for Rosen. Most scouts think he’s the most refined passer in the draft. Durability and personality questions don’t scare off Arizona.(1.0 – Josh Rosen, QB, UCLA) (2.0, 3.0, 4.0 – Saquon Barkley, RB, Penn State)Josh Rosen with a Dan Marino FAKE SPIKE pic.twitter.com/3aSY26m3m2— Eric Elizondo (@EricElizondo8) September 4, 2017 8. Bears: Quenton Nelson, OG, Notre Dame – The Bears give Mitchell Trubisky some interior line protection with the dominant Nelson. He’s been compared to Cowboys Pro Bowl guard Zach Martin, and will step in and play at a high level immediately. Nelson is a mauler and plays like a throwback. Not a sexy pick, but a solid one.(1.0 – Christian Kirk, WR, Texas A&M) (2.0, 3.0 – Denzel Ward, DB, Ohio State) (4.0 – Tremaine Edmunds, LB, Virginia Tech)Quenton Nelson (LG #56) is an elite prospect.

Bucs: Minkah Fitzpatrick, DB, Alabama – For the third mock in a row, Colin has Fitzpatrick falling to the Bucs. Tampa needs secondary help and Fitzpatrick is the prototype hybrid DB that can play safety or cover the slot. He provides attitude and leadership to a Tampa D that’s been average. Day 1 starter on a defense that needs a tone setter.(1.0, 2.0 – Quenton Nelson, OL, Notre Dame) (3.0, 4.0 – Minkah Fitzpatrick, DB, Alabama)Minkah is a God. pic.twitter.com/2Ul4FAaqqN— The Mick Nartin™ (@themicknartin) February 11, 2018

The 12-acre Roosevelt Island campus will eventually be able to house about 2,000 full-time graduate students, who will profit from proximity to New York City’s technology industry. April 23, 2013 2 min read Cornell University’s plan to build a sprawling new campus for technology innovation in New York City just got a significant financial bump. A pair of Cornell alumni has given their alma mater a $133 million gift to allow the Ivy League school to open an interdisciplinary center on the campus, school and city officials announced Monday.The center, to be called the Joan and Irwin Jacobs Technion-Cornell Innovation Institute, is named after the donors: Irwin Jacobs, co-founder of computer chip manufacturer Qualcomm, and his wife, Joan, who grew up in New York City. The institute — to be located on the Cornell Tech campus on New York’s Roosevelt Island — was reportedly part of Cornell’s original proposal to the city, but the Jacobs’ donation will allow the school to move forward more quickly than anticipated.The institute is expected to offer a two-year dual master’s degree program in the information sciences. Students will be able to focus on one of three New York City industries — media, urban planning and health and wellness, according to a press release.”Cornell Tech will bring a sharp increase in science and engineering teaching, attract students from around the world, and spin off new local companies and thousands of new jobs,” New York City mayor Michael Bloomberg said at a press conference at City Hall.Here are a few other facts about the school, which is a joint venture with Technion, a Haifa, Israel-based institute of technology:While the full campus won’t open until fall 2017, Cornell Tech accepted a “beta” class of eight full-time students in January 2013 for a one-year master of engineering degree in computer science.

This story originally appeared on Business Insider December 2, 2015 2 min read Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Google has allegedly been tracking search histories and other personal information from students, says a new complaint filed by The Electronic Frontier Foundation (EFF) with the Federal Trade Commission.The EFF claims that Google has been “collecting, maintaining, using, and sharing” data from students who use its Chromebooks in schools, and its educational apps.Google’s “Sync” feature for Chrome is enabled by default on the Chromebooks it sells to schools, according to the EFF. “This allows Google to track, store on its servers, and data mine for non-advertising purposes, records of every Internet site students visit, every search term they use, the results they click on, videos they look for and watch on YouTube, and their saved passwords,” the EFF said in a statement.The EFF finds this tracking particularly egregious because, in January, Google signed the “Student Privacy Pledge,” a “legally enforceable document,” which promises that the company won’t collect this type of information from students.“Despite publicly promising not to, Google mines students’ browsing data and other information, and uses it for the company’s own purposes. Making such promises and failing to live up to them is a violation of FTC rules against unfair and deceptive business practices,” EFF Staff Attorney Nate Cardozo said. “Minors shouldn’t be tracked or used as guinea pigs, with their data treated as a profit center. If Google wants to use students’ data to ‘improve Google products,’then it needs to get express consent from parents.”A Google spokesperson provided this statement to Business Insider:”Our services enable students everywhere to learn and keep their information private and secure. While we appreciate EFF’s focus on student privacy, we are confident that these tools comply with both the law and our promises, including the Student Privacy Pledge.”You can read the EFF’s entire complaint here.
