first_img Citation: US army to be powered by waste (2009, October 12) retrieved 18 August 2019 from https://phys.org/news/2009-10-army-powered.html British Town Demonstrates World’s First Garbage Truck Powered by Garbage The PyTEC system includes a pyrolysis tube capable of continuously consuming up to 100 kg (220 lb) of garbage an hour. Mixed waste is heated to high temperature in the pyrolisis tube, a process that releases combustible gases, which are then stored and later burned to generate electricity. The system produces five times more energy than is used to power the system.The pyrolisis process differs from other systems that generate energy by heating waste in that the heating takes place in the absence of oxygen. Aerobic systems generally need waste to be of only one type, whereas the pyrolisis system works with untreated mixed wastes. The thermal systems also need waste to be diced before being fed to the incinerator, and have problems with some components of waste, such as tin and glass. The PyTEC system does not require finely diced waste, and can handle the difficult waste sources with ease.The end products of the PyTEC system are energy and a glassy waste product that is only 5% of the volume of the original garbage. The system has been in use for a year on a British ship, the HMS Ocean. According to Qinetiq spokesperson Pat McGlead, the system has been “containerized” for the US army to make it easier to deploy. Up to ten systems will eventually be deployed, many of them in Iraq and Afghanistan, where they are expected to dramatically reduce the army’s use of fossil fuels, and take care of waste disposal at the same time. Until now the “forward operating bases” in Afghanistan and Iraq have had no formal arrangements for disposing of their waste.The PyTEC system may also find application outside the military, since many people in both commercial and private premises are seeking ways to reduce their carbon footprint and produce energy from renewable sources. Turning waste into energy has many attractions for a wide range of people.A side benefit of the PyTEC waste disposal system in conflict areas may also be a saving of lives, since there will be less need for garbage trucks to be on the roads, where they risk land mines, and other forms of attack. The systems are expected to be delivered by mid 2010, and the period of testing and evaluation is expected to last until early 2012.© 2009 PhysOrg.com (PhysOrg.com) — Defense company Qinetiq has been awarded a contract to supply the US army with a system that generates electricity from garbage.

center_img © 2012 Phys.Org Technology watchers reacting to the debut are supportive but tending to ask the same question: What will carriers do, if not openly revolt? The very idea of a crowdsourcing platform for mobile connectivity may not go down easily with carriers who may think this will hurt their business. The company says it may take time for carriers to accept the app as able to help their business. “The promise of hyperconnectivity will be fulfilled when the walls that separate the carriers’ closed garden finally open for the benefit of the industry and all users.” Benoliel has said that Open Garden already has an agreement with a “forward-looking” European carrier.Open Garden is available for Android, Windows, and Mac. The team plans for an iOS version in the future.On Monday, a reviewer said she was able to use Open Garden to surf the Internet on a smart phone using Firefox (Firefox is needed to browse with Open Garden if on an Android device, along with a browser add-on). Video streaming by way of another phone’s 4G connection, she said, looked a bit stilted but the quality was not bad.

first_img More information: www.kickstarter.com/projects/b … hnology-for-everyonebublcam.com/ © 2013 Phys.org (Phys.org) —Canada-based startup called Bubl Technology, founded in 2011, wants you to imagine being able to capture life in its bublcam, making, as it says, 360 degrees of your world available any time. The company has come up with prototypes of a little baseball-like gadget that is really four cameras arranged in a tetrahedral design, allowing a user to take photos and video. Sean Ramsey, founder and CEO, said the idea for the product was seeded some years ago, while he was working with a company in turn working with Google on a Street View project. Why not create a camera, he thought, to be capable of spherical footage for uses other than mapping? Why not use it for other things, such as panoramic photos? Explore further At the time of this writing, they have garnered $83,391 out of their $100,000 goal with 38 days to go. The target shipping date for the device, priced at over $400, is May next year.

He and other team members started thinking in terms of technology that could support a device that was small, portable,and affordable. For the last two years, the company’s focus has been on the end goal of a market ready spherical camera that captures 100 percent of the spherical range through panoramic photos and videos. The company’s hardware CTO, Dan Mills, explained: “We designed the camera in a tetrahedral [patent pending] orientation…there are no blind spots because each camera overlaps the adjoining camera.” The camera’s form factor is distinctive, as a baseball size device that is light and easy to carry around. Applications potentially, are many, including the use of the bublcam in-real estate, gaming and sports, as well as security and surveillance. The bublcam is capable of recording video at 30fps at 720p or 15fps at 1080p and exports MP4 format.For the casing, the team is using four solid aluminum die-cast structural rings. According to the company, however, the “true innovation of the bublcam is its software that allows a single, 4 quadrant multiplexed image to be stitched into a sphere. We utilize a heat mapped blending process in order to blend the final photos and videos. These are what we like to call digital bubls.”The team continues to work on the device to bring it to market and, at this stage, has fully functional working prototypes. The company has turned to Kickstarter to bring the device to market. “We have been working on bubl for the past two years and we’ve come a long way. But now we need your help,” said the campaign message. “Your support will allow us to initiate tooling, manufacturing and software development so we can make bublcam and our software available to you and the millions of people who have never before had a 360º camera option.” Ricoh shows off omnidirectional camera (w/ video)last_img read more

first_img More information: Frédérique Valentin et al. Early Lapita skeletons from Vanuatu show Polynesian craniofacial shape: Implications for Remote Oceanic settlement and Lapita origins, Proceedings of the National Academy of Sciences (2015). DOI: 10.1073/pnas.1516186113AbstractWith a cultural and linguistic origin in Island Southeast Asia the Lapita expansion is thought to have led ultimately to the Polynesian settlement of the east Polynesian region after a time of mixing/integration in north Melanesia and a nearly 2,000-y pause in West Polynesia. One of the major achievements of recent Lapita research in Vanuatu has been the discovery of the oldest cemetery found so far in the Pacific at Teouma on the south coast of Efate Island, opening up new prospects for the biological definition of the early settlers of the archipelago and of Remote Oceania in general. Using craniometric evidence from the skeletons in conjunction with archaeological data, we discuss here four debated issues: the Lapita–Asian connection, the degree of admixture, the Lapita–Polynesian connection, and the question of secondary population movement into Remote Oceania. Citation: Skulls in ancient cemetery on Vanuatu suggest Polynesians as first settlers (2015, December 29) retrieved 18 August 2019 from https://phys.org/news/2015-12-skulls-ancient-cemetery-vanuatu-polynesians.html Explore further The researchers focused on skulls dug from the bottom of a cemetery on Efate Island, which has been dated back to approximately 3,000 years ago, making it the oldest in the South Pacific. The skulls, the team reports, belong to a people known as the Lapita, who are believed to have been the earliest settlers of the islands. The team compared the skulls with those of people currently living on the island and also other parts of Polynesia and Melanesia and concluded that the ancient skulls were closest in structure to modern Asians and Polynesians. This news came as a bit of a surprise because the current natives most resemble Melanesians. The researchers believe that the evidence suggests that Melanesia people arrived sometime after the Lapita had already populated the islands in the area and interbred with the people already living there.The researchers note that other evidence of the ancient Lapita people still exists as well—those living on the island share many cultural and linguistic similarities with early Polynesians, for example. But, they also add, it still doesn’t adequately address the issue of how it was that people living 3,000 years ago managed to navigate and populate an island group so far from their home—a path that would have taken them from South-East Asia through Melanesia and then into Polynesia, while somehow not leaving any evidence that they had mixed with the Melanesians. Their findings do suggest though, that the islands of Vanuatu may have served as a springboard of sorts, offering the early settlers a place to jump to other parts of the vast Pacific Ocean. Teouma Lapita skulls. Credit: Proceedings of the National Academy of Sciences (2015). DOI: 10.1073/pnas.1516186113 (Phys.org)—A small team of researchers from France and Australia has found evidence in a very old cemetery (first discovered back in 2004) on one of the islands of Vanuatu that suggests that early Asians and Polynesians were the first human settlers, not Melanesians as many have suggested. In their paper published in Proceedings of the National Academy of Sciences, the team describes how the question of the origin of the people of the Pacific Islands has confounded visitors from the west since perhaps the 16th century and why they believe their study finally provides the answers.center_img Journal information: Proceedings of the National Academy of Sciences This document is subject to copyright.

first_imgKolkata: The Consul General of France in Kolkata, Virginie Corteval, made a day-long visit to Chandannagar, a former French colony, as part of an effort to shape the people-to-people contact between France and Bengal. As a tourist, she had visited the town about 20 years ago. In a statement issued on Sunday, Corteval said she took great pride in announcing that “we are formalising our relationship and institutionalising our partnership, working as collaborators between the government, private sector and civil society.” During her visit, the diplomat also dropped in at some Jagaddhatri Puja pandals and learnt about their themes. Also Read – Rain batters Kolkata, cripples normal lifeThe Jagaddhatri Puja is a major festival of the heritage town that attracts crowds from all over West Bengal. She thanked Chief Minister Mamata Banerjee for her commitment to develop “river tourism along the river Hooghly.” The diplomat referred to the ‘Bonjour India’ initiative of France and said the restoration and reuse of the Registry Office building in Chandannagar has given impetus to a proposal to revitalise and redevelop the entire Strand area of the town. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedChandannagar, formerly spelt as Chandernagore, situated on the banks of the Hooghly, became a French colony in 1673 when France wanted to set up a trading post. The French lost the town to the British in 1757 and regained control of it in 1816. It remained a French territory in India till 1950. “We are very grateful to the Government of West Bengal, Chief Minister Mamata Banerjee, the Minister of Tourism Goutam Deb, Minister of State for information and Culture Indranil Sen…” for their endeavour to widen this initiative to not just restoring buildings but creating livelihood opportunities and economic development for the people of this town,” the consul general said.last_img read more

Since then sleuths were looking for him. Four days ago, sleuths nabbed two more persons identified as Kalipada Mondal and Nirmal Ghosh. After interrogating the four arrested persons, sleuths came to know that Pundari had attacked Biswas before during the Kali Puja over some disputes. He was eventually resisted by local residents at that time. During investigation, it was suspected that he might try to flee to Bangladesh as the Indo-Bangla border is close to the area. Thus, police sought help from the Border Security Force to step up vigil on the border. Pundari’s picture was also provided to them. On Sunday night, sleuths got a tip-off that Pundari was hiding somewhere in West Midnapore. As Pundari was aware that he could be traced by his mobile’s location, he left it at his home in Nadia. During search operations at several places, sleuths were informed on Sunday that Pundari was hiding at Radhamohanpur in West Midnapore. The officers of the joint team of the state CID and Nadia District Police raided a house from where Pundari was nabbed on Monday morning. The house belonged to Pundari’s relative. Sleuths have seized a firearm from his procession.last_img read more
