Theyre coming Flying cars may appear in urban skies by 2023

first_imgThe flying cars depicted in science fiction classics such as “Blade Runner” and “The Fifth Element” have long been seen as flights of fancy, but their arrival is closer than you think. At least a dozen companies are prototyping or testing flying cars or passenger drones, according to a Deloitte report from January.Air taxis will number 15,000 and become a global market worth $32 billion by 2035, with aerial delivery and inspection services adding on another $42 billion, a study by Porsche Consulting predicts.Vertical takeoff and landing craft (VTOLs) carry the promise of delivering people and goods across congested urban and suburban areas in a fraction of the time a driver would need, taking cars off the road in the process. But technological and regulatory hurdles remain. And whether aerial vehicles can substantially change commuter behaviour and emissions — or overcome questions of safety and public perception — is still up in the air.Most VTOLs — or eVTOLs if they are electric-powered — resemble an oversize drone, sporting a halo of small rotors around a passenger pod and taking off and touching down like a helicopter. But they will be quieter, cheaper and greener than their heli-cousins, experts say.“Instead of this deep, guttural, penetrating-through-walls sound, you have a much more acceptable sound, similar to a ceiling fan,” said Nikhil Goel, head of product at Uber Technology Inc.’s aviation team, dubbed Uber Elevate.Uber hopes to start hauling passengers in five-seat, hybrid VTOLs above Los Angeles, Dallas-Fort Worth and a third city outside of the U.S. by 2023.“The vehicles are real. They’re coming. I think it’s going to be faster than anybody thinks is possible,” Goel said.He sees the first wave of aerial taxis providing a shuttle service between major airports and downtown vertiports that integrate into the mass transportation system, rather than leapfrogging from block to block — a hub-to-hub travel option akin to a monorail.“We are not building this product for the elite,” Goel said.A few years after the launch of Uber Air, as it’s dubbed, the cost of an aerial trip will be the same as one on the asphalt, he said.He calculates that an aerial taxi would cut a 90-kilometre commute between the downtowns of San Francisco and San Jose to 15 minutes, down from an hour and 40 minutes.Uber is not alone in setting its sights on VTOLs. Chinese drone manufacturer Ehang carried out flight tests with a single-passenger drone earlier this year, according to the company’s website. German startup Volocopter has produced an air taxi prototype, taking to the skies above Dubai in 2017. And Kitty Hawk, a California-based company funded by Google founder Larry Page, produced a sleek, one-seat VTOL prototype this year.Bell (formerly Bell Helicopter), is one of five companies Uber has teamed up with, along with Karem, Pipistrel and aerospace rivals Embraer and Boeing’s Aurora Flight Sciences.Scott Drennan, Bell’s vice-president of innovation, sees 2025 as a more realistic commercial launch target than Uber’s goal of 2023.Battery life is one area that needs to advance, with lithium-ion packs today lasting for between 50 and 100 kilometres on a multi-rotor electric propulsion system, he said.Regulations are another obstacle. To avoid crowding urban skies, VTOLs could trace existing airplane takeoff and landing routes, but at a lower altitude, buzzing along at between 150 and 330 km/h.Western aviation regulators bar out-of-sight drone operations for the most part. Discussions are ongoing with the U.S. Federal Aviation Authority and the European Aviation Safety Agency, said Drennan, who said he has also met three times with Transport Canada regarding VTOLs.Mark Cousin, chief executive of Airbus’s A3 unit, stressed the traffic management hurdles on the horizon.“The vehicle is the easy bit,” he said. “The real challenge lies in integrating thousands of these vehicles into an urban air mobility system within cities.”A3 has put out an electric-powered VTOL dubbed Vahana. The autonomous prototype launched its first vertical flight in February.Drones would typically beat other modes of transportation, such as taxis, at distances of 20 kilometres or more in congested areas, according to the Porsche study.The report notes the technology’s limited potential, stating that it can relieve some pressure from congested urban hot spots — “but only some.”“If one tried to solve all traffic problems on the ground by moving into the air, the myriad take-off and landing spots would become the new choke points.”A city with more than five million inhabitants will likely have no more than 1,000 passenger drones in operation by 2035, the study predicts. That would make a relatively small dent in ground traffic.Uber cited Los Angeles as an appealing launch city in part because of the abundance of flat roofs there — a long-standing fire safety regulation required helicopter landing pads atop tall buildings.“But they’re actually not that well suited, because it’s not just a pickup and drop-off point,” said Robin Lineberger, head of aerospace and defence at Deloitte.“It has to be a place where people come, get ready to get on the aircraft…the vehicle has to land, recharge, refuel, maybe light maintenance and inspection going on. If you think about it, it really needs to be a small, multi-function airport service area.”Large parking lots downtown are ripe for conversion into vertiports, complete with conveyor belts, charging stations and hangars, he said.Insurance would function in ways similar to a helicopter manufacturer or transport service, Lineberger said, with premiums hinging on the probability and severity of accidents.However, public perception will be an issue for the foreseeable future. Fewer than half of respondents in a Deloitte global survey of 10,000 people this year were convinced that aerial passenger vehicles would be safe, with one-third undecided and one in five disagreeing.

Commonwealth in final report says Sri Lanka polls democratic

More than 6,000 candidates from 21 political parties and 200 independent groups contested the 17 August election, which saw 225 members of parliament elected. The United National Party (UNP), which led the United National Front for Good Governance (UNFGG) coalition, increased its vote share and formed a government with the support of some members of the opposition United People’s Freedom Alliance (UPFA).Nine women were elected to Parliament, with just one nominated on the national list, meaning women make up only five percent of the total seats in Parliament.Just under 200 incidents of election-related violence were reported in the campaign period, including three deaths, grievous assaults, attacks on political party and candidate offices, and abductions, the Commonwealth observers note. (Colombo Gazette) Writing in the foreword to the report, the Chair of the Commonwealth Observer Group, former President of Malta Dr George Abela said: “Our overall assessment is that these 2015 Parliamentary elections fulfilled the key benchmarks for a democratic election and that the electoral process was on the whole transparent, peaceful and credible.” Commonwealth election observers, in their final report on the August 2015 Parliamentary elections in Sri Lanka, found that the election was democratic.The Commonwealth Secretariat today released the final report of the Commonwealth Observer Group to Sri Lanka’s 2015 Parliamentary Elections. Commonwealth Secretary-General Kamalesh Sharma made the observers’ findings public after they were sent to the Government, Commissioner of Elections and political parties following the elections. Among the recommendations offered by the Observer Group is a call for measures that make it easier for women to enter politics at the national level and a proposal that Sri Lanka take a “zero-tolerance” approach to election violence. The Group also concluded that the Government should reconsider restrictions on campaigning methods as well as consider legislation on campaign finance.The report praises Sri Lanka’s Commissioner of Elections and his Office for “having maintained high standards of fairness” and the country’s police for enforcing the law and ensuring a peaceful election. read more

Norwegian expert finds serious flaws in UmaOya project

A Norwegian expert has found serious flaws in the Uma-Oya project adding that a better comprehensive preliminary study could have prevented water ingress into the tunnel leading to a severe water dearth in some areas.President Maithripala Sirisena said that it is regrettable that series of problems have arisen during the implementation of the Uma-Oya Multi-purpose Development Project as the previous Government had hurriedly commenced the project without a proper study of the feasibility report and the Environmental Impact Assessment (EIA). Secretary to the Ministry of Mahaweli Development & Environment Mr. Udaya R. Seneviratne, the Project Director and the officials of the Norwegian Embassy participated on this occasion. (Colombo Gazette) The expert advised that it would be necessary to get special grout materials and machinery before remaining 4 and half Km of the tunnel is dug as a part of it is below the of residential areas.The expert was of the view that a better comprehensive preliminary study could have prevented the water ingress into the tunnel leading to a severe water dearth in some areas.The President requested the expert to provide a full report on how the leakage could be completely stopped and the reasons for not taking into the consideration the water  leakage in the previous reports. The mistakes have been done from the beginning and we are attempting to rectify them to ensure that the problems faced by the people  are solved and there would not be any issues in the future, the President said. President Sirisena made these remarks after the Norwegian expert submitted an interim report to the President at the President’s Official Residence in Colombo, today. The President further said that such mega scale projects should not undertake without proper studies. He also said that Uma Oya problems are lessons for the future to avoid such mistakes. President Sirisena said that the Government plans to obtain expert advice prior to implementation of the next project in which a 22 Km long tunnel is to be constructed. The expert, Bent Aagaard  said that the preliminary studies had not forecast the possibility of large water seepage in the tunnel and he further said that the machinery used for the project had not been capable of proper strengthening of the tunnel wall and seal them with strong grout materials.‘Excavation must be done by using suitable machinery on the tunnel wall and grouting all the leaks in the tunnel to ensure that there will be no seepage in the tunnel in the future,’ the Norwegian expert Bent Aagaard  said. He further said that the contractors had not been prepared for large scale water ingress in the tunnel. read more

Report More allegations of Zach Smith abuse emerge

Ohio State wide receivers coach Zach Smith talks to junior wide receiver Eric Glover-Williams prior to fall camp on Aug. 5. Credit: Colin Hass-Hill | Sports Editor.Courtney Smith, the ex-wife of former Ohio State assistant coach Zach Smith, reported violent acts performed against her to the Powell Police Department, including choking, physical abuse and death threats in October 2015, according to a report from the Columbus Dispatch. According to reporters Dean Narciso and Rita Price, Ohio State sent a lawyer to speak to Courtney Smith in her home in Powell and tried to convince her to drop the charges because, “it would embarrass OSU if she proceeded with the prosecution.” Ohio State spokesman Chris Davey told the Columbus Dispatch the university was unaware of any allegations made and would investigate. The Lantern reached out to Ohio State for comment, but did not receive a response at the time of publication. According to the reports acquired by the Dispatch, Courtney Smith reported multiple incidents of domestic violence against her, including events where, “the suspect choked her until she could not breathe” and Courtney Smith telling the police, “the suspect tells her all the time that he will kill her.” The report acquired by the Dispatch said Zach Smith’s actions against Courtney Smith stemmed from allegations she made against him that he was cheating on her with other women. Zach Smith was fired from Ohio State on July 23 after allegations were released against him for domestic violence against his ex-wife. read more

Ipso launches new symbol in fight against fake news

first_img“That means Ipso, and that’s why I’m proud that so many of our member publications will proudly display our mark on their pages.”Most national newspapers are signed up to Ipso, a voluntary independent body not backed by the Government, which acts as a regulator with its own code of conduct.The problem of  “fake news” largely disseminated on the internet has become an increasing problem in recent times with the public unclear what is false and what is genuine. The big technology information companies Twitter, Facebook and Google have been accused of failing to crack down on the spread of ‘fake news’ on their platforms. A newspaper industry logo has been launched to reassure readers that they are being protected from ‘fake news’. The new symbol has been produced by the Independent Press Standards Organisation (Ipso) to help the public in ensuring that what they read is genuine rather than ‘fake news’.Newspapers, websites and magazines signed up to Ipso, which includes the Daily Telegraph, the Sunday Telegraph and telegraph.co.uk, will be able to use the logo as a guarantee to readers they are not being misled. The slogan that accompanies the symbol states: “For press freedom with responsibility”.Ipso said the new symbol was particularly useful at a time when the “public’s trust in journalism has been undermined because of the rise of ‘fake news’.”Matt Tee, Ipso chief executive, said: “I strongly believe that Ipso membership helps our publishers distinguish themselves from the unregulated, thereby demonstrating that they choose to hold themselves accountable to higher standards.” He said the mark and what it stood for could help organisations to overcome challenges currently facing the industry.Mr Tee said: “The newspaper and magazine industry faces a number of complex challenges over the short term and I firmly believe that one of the ways in which it can thrive and prosper is by its commitment to independent, effective regulation. Ipso has issued a new symbol to help people ensure what they are reading is not "fake news" center_img Ipso has issued a new symbol to help people ensure what they are reading is not “fake news” Credit: IPSO In last year’s US presidential election, Donald Trump used the term “fake news” to attempt to discredit the mainstream American media, which remains highly critical of him. But Mr Trump is accused of using ‘fake news’ himself to boost his own popularity and standing. Last week, he retweeted videos posted by Britain First, a far right extremist organisation, which purportedly showed a ‘Muslim migrant’ attacking a Dutch boy in a park in a town outside Amsterdam. Dutch newspapers later reported that there was no evidence the attacker was either a Muslim or an immigrant. ‘Fake news’ was also voted its phrase of the year by Collins Dictionary, which estimated that usage of the term had increased by 365 per cent since 2016. It is defined as “false, often sensational, information disseminated under the guise of news reporting”. Want the best of The Telegraph direct to your email and WhatsApp?

To Potami runs dry

first_imgSunday’s snap vote saw To Potami (The River) fall from would-be kingmaker to bit player, putting its political future in doubt.The centrist pro-market party won 4.09 percent, about 2 percent down on its previous result eight months ago, and far from the 10 percent target set by its leader, Stavros Theodorakis. In absolute numbers, it lost 151,780 votes compared to January’s elections. Potami was reduced to sixth place, behind neo-fascist Golden Dawn, the left-of-center PASOK socialists and the Greek Communist Party (KKE), as well as front runners SYRIZA and ND.Exploring the reasons behind the party’s poor performance reveals a mix of political circumstance, character, strategy and ideological credo. Some of the traits have plagued other liberal projects in recent years.PolarizationExtreme polarization – partly because opinion polls had pointed to a tight race between SYRIZA and New Democracy (ND) – no doubt stole a considerable chunk of votes away from Potami. Early exit poll data indicate that 17.2 percent of those who voted for the party in January defected to SYRIZA, while another (surprisingly smaller) 14.5 percent went to ND. Just over half of those who voted for Potami in January renewed their support. In the end, and much to the embarrassment of most pollsters, the leftist party of Alexis Tsipras went on to win the vote with a comfortable 7.5 percent margin.Potami’s purportedly pragmatic strategy to announce that in order to “save” the country it would be willing to join either a right-wing or left-wing government and serve as the balancing force did not seem to resonate with voters.“The deeply nonpartisan message ‘I can cooperate with ND and SYRIZA if it means preventing the country from being left without a government’ eventually backfired. ‘In that case,’ voters said, ‘why not give my vote straight to ND or SYRIZA?’ And this is what they did,” Potami candidate Petros Tatsopoulos said on Facebook. Perhaps more controversially, Tatsopoulos said the party should shed its pretentions of being the “virtuous loner” and seek to join forces with PASOK.PopulismFounded in February last year, Potami found itself slap-bang in the middle of a tectonic shift in the Greek political landscape caused by the devastating debt crisis. As the two mainstream parties PASOK and New Democracy lost their supremacy, smaller movements began mushrooming along the bailout fault-line, aligning themselves either for or against.But Potami positioned itself as a post-bailout and post-political movement firmly anchored in the European Union and the eurozone. It shunned the typical trappings of Greek politics. Instead of flag-waving rallies, its leader, a former TV journalist, opted for small town-hall meetings with a seated audience.Instead of creating a youth wing replete with chants and slogans, Theodorakis wandered around beaches passing out portable ashtrays to smokers and set up eco-friendly camping tents as campaign kiosks to attract disenchanted urban voters. He preached pragmatism, reason and common sense while calling for radical reform of the country’s dysfunctional public sector. Around him, he gathered a motley crew of academics, businessmen and nonpolitical individuals.Less than a year after its creation, Potami seemed to have succeeded where other liberal-leaning parties had failed after gaining 6.05 percent and 17 seats in Greece’s Parliament. But then things turned sour.The aversion to populism was key to the party’s failure, according to Stathis Kalyvas, professor of political science at Yale. Given Theodorakis’s visibility and popularity, Kalyvas says, the absence of populism meant that his appeal would find a limited market mostly consisting of intellectuals and intellectual professionals.“There are just not as many of them, especially in a time of crisis when downwardly mobile intellectuals tend to be particularly spiteful and hence not open to the serious and optimistic message of Potami,” Kalyvas said.However, its cerebral message was not Potami’s only impediment.In Parliament, with few exceptions, Potami MPs seemed muted and awkward. Despite its abhorrence of populism, the party’s most visible MPs, apart from a former general secretary of revenues, became a second-rate actor and a former travel show presenter – neither academics nor intellectuals. Its slick marketing was not accompanied by a clear political message. And Theodorakis himself lacked political gravitas, often giving the impression he was acting the part of a political leader, reading his lines in his smooth TV presenter’s voice.To make matters worse, Theodorakis’s dispassionate everyman was obliterated by the supernova of Alexis Tsipras, the youthful, magnetic leader of SYRIZA who was convinced – and convincing – that he was on a mission to save Greece and change Europe.“Even if Theodorakis had picked populism, the niche was already taken by the time he emerged, and SYRIZA had a first-mover advantage,” Kalyvas said.ElitismAlthough Theodorakis assumed responsibility for the poor electoral result, he did seem to claim the high ground, feeding allegations of elitism.“Maybe in times of crisis society is not in a position to make a cool assessment of the situation and to give its support to a party that represents reason and progress,” said Theodorakis, lending weight to critics bothered by the party’s alleged elitism and intellectual snobbery.Writing for the website Protagon in the wake of election day, liberal author and former Potami member Nikos Dimou too appeared to suggest that the root causes of defeat lay with the public, and not the product.“Everyone, even rivals, agreed [Potami] had the best officials. But that too was destroyed by this abhorrence of excellence. You put a man like [constitutional expert] Nikos Alivizatos in a prominent position? You’re asking for it. A party ruled by excellence and reason has no business in a Roman bazaar,” he wrote.NetworkMuch in keeping with its post-political profile, Potami decided to skip local party organizations across the country, a standard but costly tradition for Greece’s mainstream political parties. Instead, Potami relied for the most part on an Internet-based campaign that affected its influence – particularly in the Greek countryside.“In a low-turnout election, where MPs were elected according to their position on the lists of party candidates [rather than the ‘crosses,’ or votes, each received], campaigning is crucial. As a result, Potami’s presence was weak outside Athens,” said Spyros Kosmidis, a political expert at Oxford University.On top of that, Potami was damaged by low turnout among young voters, the party’s main reservoir of support.VanityNone of the liberal parties launched in Greece in the past 15 years – including the Liberals of Stefanos Manos, Drasi, Democratic Alliance and Dimiourgia Xana (Recreate Greece) has been able to break into the mainstream. Analysts tend to point out Greek liberals’ inability to communicate their message, to do single issue politics and get involved in the daily grind of Greek politics. Another reason is the vanity of small differences: Despite their similar platforms, parties are unwilling to compromise on basic issues, leaving the country without a meaningful center-left.It is happening again. As Potami’s licks its wounds, the once-dominant PASOK is waiting around the corner. A subtle overture from Socialist officials on Wednesday was turned down by Theodorakis, who said that the party would either “remain independent or break up.” He said he was not willing to see the party “become an appendage to New Democracy, PASOK or SYRIZA” and called a congress for the beginning of December, where members are expected to debate what went wrong during the election campaign.“I find it hard to believe that PASOK and Potami would join forces so long as Theodorakis remains in charge of the party. Timing will certainly play a key role in any future move,” Kosmidis said, adding two more critical factors: the identity of ND’s next leader and the trajectory of SYRIZA’s popularity.Purists certainly fear that a merger would pollute Potami beyond recognition. The recent election of Fofi Gennimata, an old-school PASOK apparatchik whose father was a senior party official, as the Socialist leader, has fed to skepticism. On the other hand, analysts say a collaboration would bring together the newcomers’ know-how and intellectual seriousness with the Socialists’ far-reaching network of local organizations.For Alexandra Patrikiou, an expert in political history, a merger would be a boon for the country’s fragmented center-left. But it also seems inevitable for Potami.“The absence of a clear political identity was not necessarily a handicap. It made the party more flexible and more adaptable, at a time when that was necessary,” Patrikiou said.“But this absence renders the party hostage to circumstance. It means that it will not be able to survive long-term unless it transforms itself into something different. Today’s strength will become tomorrow’s weakness,” she said.Source: Kathimerini Facebook Twitter: @NeosKosmos Instagramlast_img read more

Messenger découvre de la glace en abondance sur Mercure

first_imgMessenger découvre de la glace en abondance sur MercureDe nouvelles observations réalisées par la sonde Messenger montrent que la planète Mercure recèle bien de grandes quantités de glace ainsi que d’autres matériaux gelés et volatiles dans ses régions polaires. Mercure est peut-être la planète la plus proche du Soleil mais cela ne l’empêche pas d’abriter de la glace en abondance. Une hypothèse que les spécialistes avaient émise depuis longtemps mais qui n’avait jusqu’ici pas pu être vérifiée. En effet, la planète où la température moyenne est de 169 degrés, paraît être le dernier endroit où trouver de la glace. Néanmoins, Mercure présente une particularité : son axe de rotation est incliné seulement de un degré. Cela signifie que certaines zones aux pôles de la planète ne voient jamais le Soleil et donc que les températures y sont très froides.  Il y a plusieurs décennies, des spécialistes ont ainsi suggéré qu’il pouvait y avoir de la glace d’eau voire d’autres composés glacés dans ces fameuses zones. Une hypothèse confortée en 1991 lorsque le radiotélescope Arecibo à Porto Rico a détecté des plaques aux pôles de la planète. Mais un grand nombre de ces plaques correspondaient à l’emplacement de vastes cratères d’impact cartographiés par la sonde américaine Mariner 10 dans les années 1970. Or, dans la mesure où Mariner n’avait pu observer que 50% de la planète, les chercheurs manquaient d’un diagramme complet des pôles pour pouvoir comparer les images. Ceci ne confirmait donc pas pleinement l’hypothèse mais grâce à Messenger, c’est désormais chose faite.En effet, les observations réalisées par la sonde arrivée en 2011 autour de Mercure, ont confirmé la présence de glace et d’autres composés gelés aux pôles de la planète. Les images prises ont montré les fameuses plaques plus ou moins brillantes dans les zones sombres des régions polaires. Et les instruments à bord de la sonde, notamment un spectromètre à neutrons, ont eux, permis d’établir qu’il s’agissait bien d’eau. Ils ont également servi à mesurer précisément les volumes. Ainsi, les nouvelles données indiquent non seulement qu’il y a bien de la glace sur Mercure mais aussi que cette dernière représente le principal constituant des dépôts trouvés au pôle nord. De la glace enterrée sous un mystérieux matériau sombre “La glace d’eau se trouvant dans les régions polaires de Mercure atteindrait plus de trois kilomètres d’épaisseur si elle était étendue sur une superficie de la taille de Washington DC à savoir 117 kilomètres carrés”, a expliqué David Lawrence, scientifique de la mission Messenger à l’Université Johns Hopkins à Laurel. Les résultats montrent en outre que la glace est exposée à la surface des dépôts les plus froids, mais que celle-ci est enterrée sous un matériau particulièrement sombre dans la plupart des dépôts, où les températures sont un peu trop chaudes pour que la glace reste stable à la surface. “Nous estimons que selon les mesures effectuées avec le spectromètre, la glace se trouve sous une couche de 10 à 20 centimètres d’épaisseur d’un matériau sombre moins riche en hydrogène”, a ainsi précisé David Lawrence. En effet, ce sont les mesures de la concentration d’hydrogène qui ont permis d’évaluer les quantités d’eau gelée. “La couche enterrée présente une teneur en hydrogène régulière avec de la glace d’eau quasiment pure”, a ajouté le chercheur dont les travaux, ainsi que deux autres études, sont publiés dans Science. À lire aussiDes chercheurs auraient découvert l’origine de la mystérieuse lumière verte observée par la NASAQuant à l’origine du fameux matériau sombre, là-aussi, les chercheurs ont leur petite idée. “Ce matériau est probablement formé d’un mélange organique complexe apporté sur Mercure par des impacts de comètes et d’astéroïdes, les mêmes objets cosmiques qui ont sans doute apporté de l’eau sur la planète” ainsi noté David Paige, de l’Université de Californie à Los Angeles, auteur de l’une des deux autres études. Selon lui, le mélange aurait foncé avec le temps et l’exposition à de fortes radiations à la surface de Mercure. De nouvelles questions au sujet de Mercure “Ce matériau isolant et sombre est un nouveau pli pour l’histoire. Depuis plus de 20 ans, le jury a délibéré pour savoir si la planète la plus proche du Soleil abritait de la glace d’eau en abondance dans ces régions polaires ombragées en permanence. Messenger a maintenant fourni un verdict affirmatif et unanime”, a commenté Sean Solomon, principal investigateur de la mission de la sonde cité par la NASA. Néanmoins, ces observations soulèvent aussi de nouvelles questions. “Ce matériau sombre dans les dépôts polaires est-il principalement constitué de composés organiques ? Quel type de réactions chimiques ce matériau a t-il subi ? Existe t-il des régions sur ou à l’intérieur de Mercure qui abritent à la fois de l’eau liquide et des composés organiques ? C’est seulement en continuant l’exploration de Mercure que nous pouvons espérer faire des progrès sur ces nouvelles questions”, a conclu Sean Solomon.

Aussie cyclist needs skin graft after iPhone explodes

first_imgWhen you think about cycling injuries, cuts, scrapes, bruises — maybe even the odd sprain or fracture might come to mind. A severe burn requiring grafts probably isn’t on the list.That’s exactly what happened to 36-year old Australian Gareth Clear when he was out biking recently. Clear was enjoying a ride on the extensive network of paths at Manly Dam. It’s a gorgeous place to go for a ride — here’s a short clip so you can see for yourself:Clear’s recent ride wasn’t quite as enjoyable, however. It was cut short when the iPhone 6 he’d been using for the past six months suddenly started to burn right in his pocket.This particular incident doesn’t appear to have been caused by a shoddy third-party charger or cable, at least not directly. Clear’s comments about the incident seem to indicate that he fell on top of it, and presumably onto something hard that managed to penetrate the iPhone’s aluminum back cover and puncture the internal battery.“The phone did hit the ground, it didn’t spontaneously combust,” Clear said. Once the battery was damaged, the reaction quickly set his phone ablaze. It burned through his shorts and two layers of skin. Doctors at the Royal North Shore Hospital patched him back up, but Clear will spend the next week recovering at home. He’ll be tethered to an antibiotic drip to help ensure the burn doesn’t become infected.Apple has contacted Clear and said they’re going to investigate the incident. There could have been other contributing factors besides the damage sustained — and if there were faulty components inside Apple definitely wants to know about them.last_img read more

Heavy rain in Kerala to continue for 4 more days death toll

first_imgView of a flooded area in northern Kochi, Kerala, on August 18, 2018.  (Photo by – / AFP) (Photo credit should read -/AFP/Getty Images)Heavy rains have lashed out several parts of Kerala with at least four people reported dead. The Indian Meteorological Department has said that the rains will continue for four more days.The intense monsoon rains have dilapidated many areas, mostly in the coastal and high ranges. The IMD has also issued a red alert to Kasaragod and Idukki districts on Sunday. Orange and yellow alerts have also been issued in many districts due to the intense rains that have created a flood-like situation in the state.Strong winds with a speed of 40-50 kmph from Westerly direction are expected along the Kerala coast. “Sea condition will be rough to very rough. Fishermen are advised not to venture into the sea,” stated IMD.Around 835 people are living in 10 relief camps across Thiruvananthapuram, Kollam, Alappuzha, Thrissur, Kozhikode, and Kannur districts.Four fishermen who went missing returned safely on Saturday morning. The fishermen had set out from Vizhinjam harbour in Kollam district on Wednesday. The coastal police are still conducting search operations for the Tamil Nadu fishermen whose boat capsized at Neendakara in the district.The Thiruvananthapuram district administration has restricted entry to the famous Shankumugham beach due to bad weather. Many houses have also been damaged in the coastal areas of the district.A minor landslide was reported from Konnathady village in Idukki district but no casualties were reported. Many of the dam shutters have been opened in the state. The shutters of Kallarkutty, Bhoothathankettu, Malankara and Pambla dams were opened to drain out excess water. More dams are expected to open on Sunday.Even as the monsoon intensifies across the state, the state is facing a 17 per cent rain deficit. The southern peninsula is currently facing a high monsoon rain deficit.last_img read more

Laura Bush Says Immigration Policy Cruel

first_imgTwitter via @YahooNewsFormer first lady Laura Bush says the policy of separating immigrant parents and children along the nation’s southern border is “cruel,” ”immoral” and “it breaks my heart.”Bush was writing a guest column for The Washington Post Sunday and compared the policy to the internment of Japanese Americans during World War II.“I appreciate the need to enforce and protect our international boundaries, but this zero-tolerance policy is cruel,” she wrote.She said “the U.S. government “should not be in the business of warehousing children in converted box stores or making plans to place them in tent cities in the desert outside of El Paso.”She said it was “eerily reminiscent of the Japanese American internment camps of World War II,” which she said are “now considered to have been one of the most shameful episodes in U.S. history.” Sharelast_img read more

first_img Related Content The last couple of years in the United States and Europe have seen an increased focus on the cumulative patient dose received from a wide variety of X-ray devices including classical X-ray, computed tomography (CT), interventional radiology and mammography. The deleterious effects of radiation dose have received widespread coverage, and the partial answer has been a movement towards non-ionizing diagnostic imaging equipment, such as magnetic resonance imaging (MRI) and ultrasound.The increased use of ultrasound both in diagnostic and guided applications, as well as in specific venues such as the emergency room, is well documented and continues to rise. This rapid increase is expected to continue as the newer ultrasound units, especially hand-carried and hand-held units, continue to improve and as new and better software applications for noise reduction and image enhancements become available.The relatively low-energy acoustic waves used in ultrasound, which make for a relatively safe diagnostic imaging environment, lead to difficulties penetrating thick layers of human tissue. With approximately two-thirds of the U.S. populations estimated to be obese and other estimates showing that more than 50 percent of all abdominal scans are of technically difficult patients (typically with a BMI in excess of 30), this problem dominates the diagnostic ultrasound market in both the United States and Europe. Also, various sources estimate the average exam of a difficult patient takes 20-40 percent longer – if it can even be carried out. The liver and other key abdominal organs can lie 4 to 5 centimeters below the surface in difficult patients. This presents great difficulties in achieving good diagnostic quality ultrasounds and places more physical strain on sonographers and radiologists. Radiologists must use a lower frequency probe to penetrate the tissue, which leads to a concomitant loss of resolution. In cases where the low-frequency probe fails, the radiologist must resort either to a more expensive and time-consuming MRI exam or a dose-producing CT exam. The ultrasound industry has recognized this challenge and developed a number of technologies both in software and hardware to address it. Leading probe manufacturers have attacked the problem via advanced design and materials. Software suppliers have also developed targeted approaches to penetrate the deep tissue. For example, ContextVision’s newest ultrasound image enhancement product includes a directed, focused image enhancement mode. This mode allows the user to enhance deep-lying organs without over-effecting mid- and near-field structures. When combined with the newest probe technology, this image enhancement technology will alleviate some of the issues associated with ultrasound examinations of technically difficult patients. Donald Barry is director of commercial development for ContextVision, which is an independent developer of medical imaging enhancement, analysis and processing technologies, serving leading OEMs and distributors for more than 25 years.

Freddie Mac Expands Transparency on LoanLevel Data for Investors

first_img in Daily Dose, Government, Headlines, News Freddie Mac made its goal of attracting more investors back into the secondary mortgage market more of reality this month by adding 21.5 million single-family mortgages to the government-sponsored enterprise’s single-family loan-level dataset.Prior to these additions, the data available to investors remained limited to loan level data and loss data on 30-year, fixed-rate single-family loans. With this new information, Freddie says potential investors interested in credit risk can now see loan level data on 3.3 million, 15- and 20-year fixed-rate single-family mortgages, originated between Jan. 1, 2005 and Dec. 31, 2014. In addition, the database includes 18.2 million, 30-year, fixed-rate mortgages originated between Jan. 1, 1999, and Dec. 31, 2014.For Freddie Mac, transparency is the key to regaining investor confidence.”Providing investors with this expanded view of credit risk for additional fixed-rate single-family mortgages will enable us to grow and evolve our credit risk offerings by expanding the products available for risk transfer and increasing the amount of risk transferred to private investor,” said Kevin Palmer, senior vice president of credit risk transfer for Freddie Mac. “Releasing this data now will help give potential credit investors sufficient time to analyze Freddie Mac’s actual loss performance.”Investors reviewing the information will receive the following: a loan’s monthly performance, credit performance, and property disposition information.The data will not include adjustable-rate mortgages, loans with balloon payments, interest-only loans, government-insured mortgages or loans refinanced through the Home Affordable Refinance Program and other affordable or non-standard mortgages, Freddie said.”Freddie Mac continues to look for opportunities to transfer mortgage credit risk to private investors in an economically sensible way,” Palmer said when discussing the reasoning behind the new loan data. “Adding all fixed-rate products to our Single-Family Loan-Level Dataset allows us to explore other credit risk transfer opportunities.” Freddie Mac Investors Loan-Level Data 2015-12-23 Kerri Panchuk December 23, 2015 567 Views center_img Share Freddie Mac Expands Transparency on Loan-Level Data for Investorslast_img read more
