Silent running UAV looks like a bird capable of invisible surveillance

first_imgDrones have already proved very effective on the battlefield in both surveillance and attack configurations. But there’s growing concern over how extensively drones will be used by the authorities for surveillance and tracking of civilians.If such drones take the form of small aircraft, they should be easy to spot in the sky, and you’ll also be able to hear their engines. But a new drone has been shown off during the HOMESEC 2013 defense and security conference that will be able to hide itself in plain sight.Spanish defense manufacturer EXPAL has demonstrated a drone at HOMESEC 2013 that looks like a gliding bird. Not only that, but the unmanned aerial vehicle (UAV) will function using a noiseless motor, meaning you won’t hear it flying above you. Anyone looking up will just see a gliding native bird that looks natural and will most likely be disregarded as anything suspicious.The UAV is called SHEPHERD-MIL and has already been put into operation as a bird strike avoidance system. EXPAL wants to expand its uses, though. With both cameras and a geolocation system on board, SHEPHERD-MIL is being modified to work as a surveillance drone, an aid to firefighters, and for use during drug trafficking operations.So, next time you see a bird gliding above you, it may be just a bird, or it could turn out to be a surveillance drone doing a pass and checking for suspicious activity. Combine that with the ongoing development of tiny UAVs, and detecting when surveillance is underway is only going to get more difficult.last_img read more

Tommy Source: Michelle LongTOMMY LONG HAS finally received his long-awaited scoliosis surgery after numerous delays.Last week Tommy (6) had his sixth surgery, where a rod that was removed from his back in September was has been following his story since last year. Tommy, who is from Kilkenny, had a vector rod inserted in September 2014, followed by a couple of lengthening sessions.Issues with the rod developed and he was waiting seven months for these to be fixed. A magnetic rod known as a magec rod was inserted in January 2016. In September, the rod became unhooked and cut through his bone. It was finally replaced last Tuesday.Tommy’s mother Michelle told us how relieved she was after the surgery. Tommy’s back“It all went really well. They removed the vertebrae they needed to and put in one magec rod. They felt the second rod wouldn’t work for him for now.“His back looks amazing. The consultant spoke to us and he said Tommy was unrecognisable. I can’t wait to see him standing.“When he came out the difference was unbelievable, even from the front – you can see the difference it has made to his tummy and rib cage, and when he’s lying on his side his back looks really straight.He hasn’t complained at all. He’s good, he’s sore but he has a really high tolerance of pain at this stage, he’s a very brave boy. He was in surgery for 10 hours.Tommy’s curve was measured just before the surgery and it was 95 degrees.Michelle says the worst is hopefully over and the family is now focused on getting Tommy back on his feet. TommyShe and her husband have been taking it in turns to stay with Tommy overnight, sleeping on the hospital floor.“The recovery will take a while, but he’s not at risk anymore. The plan is if the rod works as it should and doesn’t break, he won’t need another surgery for two years.”The rod can be lengthened without surgery in the meantime, as he gets taller.Waiting lists Scoliosis affects about 1% of children and adolescents in Ireland. The condition can also affect adults. It causes an abnormal curve of the spine or backbone.With scoliosis, a person’s curvature progresses over time and waiting a long period for surgery often leads to other complications and means the patient can require more serious surgery. Michelle and Tommy last month Source: Órla Ryan/TheJournal.ieAs of the end of January, there were over 200 patients under the age of 18 waiting for scoliosis surgery in Ireland, including 190 people at Our Lady’s Children’s Hospital, Crumlin (OLCHC) – some of whom have been waiting for over 18 months. Source: National Treatment Purchase Fund (NTPF)The government has committed to cutting the average waiting time for surgery to four months by the end of 2017.As of this month, a new orthopaedic theatre at OLCHC is open one day a week, with additional capacity being provided once extra employees are recruited in the coming months.Read: ‘The damage is done, a piece of his spine will have to be removed’Read: ‘I see my daughter crying in pain, her body bending over.

Pet owners urged be wary over Easter as experts warn of poisoning

first_imgPet owners urged be wary over Easter as experts warn of poisoning risks Some traditional Easter treats and gifts can be dangerous to animals. Thursday 18 Apr 2019, 1:08 PM By Stephen McDermott Image: Shutterstock/Litkouskaya Veranika Apr 18th 2019, 1:08 PM IRISH PET OWNERS have been urged to be wary of hidden dangers in the home this Easter weekend.Pet specialist retailer Petmania has warned how some traditional Easter treats and gifts can be dangerous to animals, including chocolate, hot cross buns and even flowers.The company has reminded owners that chocolate is particularly poisonous to both cats and dogs and can leave them feeling extremely ill.To avoid this, it says that Easter eggs should be kept out of reach and that children should not feed their pets any chocolate.Hot cross buns should also be kept out of reach as they present a similar hazard to cats and dogs, with the raisins and sultanas in them so toxic that they can cause severe kidney failure.And perhaps surprisingly, spring flowers such as lillies and daffodils can also be poisonous to pets.Dogs or cats who like digging in the garden are particularly at risk, as eating the bulbs or flowers can make pets sick, while those who drink water from a vase with flowers can also become unwell.Petworld says owners of pets who accidentally ingest any of these substances should contact a vet who can advise on whether any attention is required.Owners are reminded to keep the number of their vet handy so that if they suspect their pet is in trouble, they can get them medical assistance as soon as possible.

Migrant workers shot in pay dispute

first_imgTwo men have been arrested in Greece after foremen for strawberry growers allegedly shot and wounded 27 migrant labourers who were demanding to be paid, police said. The migrants, mainly from Bangladesh, were hospitalised in the western port of Patras and other areas with gunshot wounds after allegedly being fired upon late on Wednesday by three foremen for the growers in the village of Manolada, one of the main areas of strawberry production in Greece. One man was arrested as a “moral instigator” of the alleged shootings and another for helping two of the presumed perpetrators to evade arrest, local police said on Thursday. The migrants had been working in local farms without being paid for the past six months, the police said. Around 200 of them went to demand their money when they were fired upon. The government condemned the attack and anti-racist groups were planning a demonstration in the area later in the day. Government spokesman Simos Kedikoglou said the attack was “inhuman” and “outside Greek morality” and pledged an immediate response by the authorities. But the Communist-affiliated PAME union noted that the incident was only the latest in a long history of abuse of migrant workers in Greece. PAME said the workers had been fired upon with shotguns and pistols. It claimed 33 were hurt, while the police said 27 were wounded, one of them critically. “Growers and landowners have operated with cover from the government and justice for years, creating a hell-hole with slavery labour conditions,” the union said. “Modern slaves in Manolada work in stifling conditions, pay rent to their exploiters and are lodged in sheds without water and electricity,” it said. In 2008, Manolada had been the focal point of a rare strike by hundreds of migrant workers against near-slavery conditions on the fields. The treatment of migrants in Greece has long been criticised by domestic and international rights groups, to little avail. Source: AFP Facebook Twitter: @NeosKosmos Instagramlast_img read more

Aegean island on sale for just 14 million

first_img Facebook Twitter: @NeosKosmos Instagram An uninhabited private island off the coast of Greece will go on auction at a starting price of 10 million euros (AU$14,34 million) in September, the company organising the sale has announced.The island is part of the Spalathronisia archipelago that sits 500 metres from the Halkidiki peninsula, a tourist hotspot in northern Greece. The sale of the island is the latest from the country’s crisis-hit landowners.The auction of the 10.4-hectare Aegean island looks set to outstrip the sale in March of six Ionian private islands to the Emir of Qatar, Hamad bin Khalifa al-Thani, who reportedly paid 8.5 million euros for them.Greece’s privately owned islands have been sold off in greater numbers due to a recent increase in property taxes by the government.Russian billionaire Dmitry Rybolovlev’s daughter bought the Greek resort island of Skorpios in April, where shipping tycoon Aristotle Onassis married Jackie Kennedy in the 1960s.The sale price was not specified, but Greek media reports placed the value of Skorpios at more than 100 million euros.The Greek government has also got in on the act, but has agreed to long-term loans rather than sales of its own island assets.Source: read more

ECCV launches new project

first_img Facebook Twitter: @NeosKosmos Instagram Victorian multicultural organisations will be given strategic and practical support to improve their governance through a new project initiative launched by the Ethnic Communities’ Council of Victoria (ECCV).The Futures Project, funded by the Scanlon Foundation and in partnership with the Australian Multicultural Foundation and Leadership Victoria, will provide governance support for volunteer driven, ethno-specific and multicultural organisations.The project aims to provide a governance model through which multicultural communities will work together through their respective organisations, building and strengthening cross-cultural connections and relationships.“This project has been created to address an identified need for greater governance of ethnic and multicultural organisations; a need that ECCV recognises will continue to challenge the sector,” said ECCV chairperson Eddie Micallef. “Through forums, targeted support and ongoing mentoring, the project will provide a variety of long-lasting benefits to ethnic and multicultural organisations.“This includes providing a strengthened ethnic and multicultural community sector by improving organisational governance capacity.“The mentoring element of the project will assist ethnic and multicultural organisations who are finding it difficult to plan for the future and more recently established organisations that need support to enable them to thrive and grow,” he said.The Futures Project aims to provide a high level of information, resources and opportunities around governance which will work to build the confidence of ethnic and multicultural organisations to actively participate and contribute to the social, cultural and economic vibrancy of community life in Victoria. last_img read more

Princess Piers WWI connection remembered

first_imgOne hundred years ago, before the influx of Greek migrants touched down at Princess Pier in Melbourne, thousands of Australian families gathered to farewell their male family members making the trip up north to help the Allied forces. Thousands of Australian men would have said their last goodbyes at the pier before they settled at the base in Lemnos, Greece, before the tragic voyage to Gallipoli. Princess Pier was where the first Australian contingent of troops set off to the Great War, and it was where hundreds gathered 100 years later to mark the moment and remember those who paid the ultimate sacrifice for their country. At an Anzac Centenary commemorative ceremony at the pier on Sunday, Greek Australians joined the crowd to pay their own respects and share the Greek connection to a huge part of Australian history. The Lemnian connection was represented in a stall set up by the Lemnos Gallipoli Commemorative Committee (LGCC), where passersby were able to see photos of nurses and other personnel on the island and get a small history lesson on the lesser-known Greek connection.Christina Despoteris, executive member of the LGCC, says the stall was packed with people keen to find out more about Greece’s connection.“There were lots of people – lots of interest,” Ms Despoteris tells Neos Kosmos. “We had pictures of nurses on the island, we had pictures of the hospital there, pictures of soldiers, and they came and had a look at those.” For Ms Despoteris, the day marked the start of the commemorative period, that will span four years just as the war did. For many who saw their loved ones off at Princess Pier in 1914, they were blissfully unaware of how long the war would span and how bloody it would eventually become.The island of Lemnos still holds a special place in Australian history. More than 100 Australian soldiers are buried there, while some of the first Greek migrants to travel to Australia were in fact Lemnians.“Lemnos is slowly becoming acknowledged as part of the history of Gallipoli. Our role is to encourage and to make sure that more and more people know of it,” Ms Despoteris says.Each of the 17 ships of the first convoy farewelled at Princess Pier had its own stall at the event, giving crowds the chance to learn of the soldiers who were on board and their fate. For the LGCC, the event was a chance to fundraise and garner interest in the forthcoming statue, to be erected midnext year. The group sold out of their fundraising badges, raising more than $600 for the statue.Commissioned by sculptor Peter Corlette, the bronze statue depicts two figures, one a nurse standing tall, looking after a seated soldier.The statue will be erected at Albert Park, linking it to the nearby Princess Pier legacy. The committee is also organising a photographic exhibition, displaying a myriad of photos from the island during the war, with the hopes it will tour the country during the centenary commemorations.

Les militants ont été interpellés et le train a été débloqué vers 5h du matin.Réclamant un moratoire sur l’exportation des déchets nucléaires, une dizaine de militants de l’association écologique Greenpeace se sont enchaînés aux voies de chemin de fer à l’arrière et à l’avant d’un train transportant de l’uranium appauvri. En provenance de l’usine Areva de Pierrelatte dans la Drôme, c’est en Loire-Atlantique à Montoire-de-Bretagne, que la cargaison doit être acheminée avant d’être embarquée à bord du cargo russe Kapitan Kuroptev à destination de la Russie, assure Greenpeace.À lire aussiGreenpeace : une vidéo choc pour sauver la Grande barrière de corail L’association mène de nombreuses actions, notamment au Havre et à Cherbourg, pour protester contre ces exportations.

first_imgDeux loutres blanches naissent en captivité, découvrez-les en imagesGrande-Bretagne – Deux loutres blanches sont nées au Blue Planet Aquarium, dans le comté du Cheshire. C’est la première fois que de telles naissances ont lieu en captivité. Les deux animaux font partie d’une portée de trois jeunes loutres cendrées (Aonyx cinereus) nées à la fin du mois de mars dernier. Ce n’est que lorsqu’elles ont mis le museau hors de leur terrier il y a quelques jours que le personnel du Blue Planet Aquarium a découvert la remarquable caractéristique de deux d’entre elles. Les jeunes loutres passent en effet les premières semaines de leur vie cachées à l’intérieur de leur tanière. À lire aussiL’étonnante éclosion d’œufs du crapaud de SurinamTom Cornwell, responsable des expositions, explique : “En temps normal, les jeunes comme leurs parents sont bruns argentés.

Les deux jeunes sont atteints de leucistisme, une particularité génétique qui confère à leur pelage une couleur blanche, sans affecter leurs yeux (contrairement à l’albinisme). “En parfaite santé et pleines d’énergie”, toutes deux devraient faire la joie des visiteurs venus les admirer.Découvrez les images : 13 mai 2010 à 13:01 • Emmanuel Perrinlast_img read more

Picard un microsatellite pour étudier lactivité solaire et son impact climatique

first_imgPicard : un micro-satellite pour étudier l’activité solaire et son impact climatiqueRussie – Le micro-satellite Picard doit être lancé ce mardi depuis le cosmodrome de Yasny en Russie. Il aura pour mission d’étudier les variations d’activité du Soleil et leur éventuel impact sur le climat de la Terre.Comme le souligne le Centre national français d’études spatiales (Cnes), “pour certains experts, plus de 80% du changement climatique actuel proviendrait des gaz à effet de serre et 10-20% du Soleil. Mais tout le monde n’est pas d’accord avec ces proportions”. C’est pour tenter de mieux comprendre l’influence de l’activité solaire sur le climat terrestre que le satellite Picard doit rejoindre cette après-midi son orbite.Conçu pour mesurer la vitesse de rotation du Soleil, sa puissance rayonnée, la présence de taches à sa surface ou encore sa forme et son diamètre, Picard recueillera des données précieuses qui permettront aux scientifiques d’évaluer l’éventuel impact de notre astre et ces cycles sur l’augmentation des températures terrestres. Ce micro-satellite d’un poids de 150 kilos porte le nom de l’astronome français Jean Picard qui, au XVIIe siècle, fut le premier à mesurer le diamètre du Soleil et sa relation avec l’activité solaire.Picard, qui devrait observer le Soleil pendant deux ou trois ans, doit être placé en orbite par un lanceur Dnepr à 725 kilomètres d’altitude, depuis le cosmodrome de Yasny, en Russie. Il embarquera trois instruments, Sodism, Premos et Sovap, qui permettront de mesurer les variations géométriques et énergétiques de l’étoile.Le 15 juin 2010 à 17:28 • Emmanuel Perrinlast_img read more

Quatorze ours gardiens de plants de cannabis découverts au Canada

first_imgQuatorze ours gardiens de plants de cannabis découverts au CanadaCanada – Les propriétaires de plants illégaux de cannabis ont eu l’étrange idée de recruter des ours pour protéger leur future récolte. Au moins quatorze animaux avaient été mobilisés lorsque la police a découvert les plants.Selon la police, les deux producteurs de marijuana attiraient les ours sur leur propriété de Colombie-Britannique en les appâtant avec de la nourriture pour chien. Une méthode plus qu’originale pour éloigner les voleurs de leur précieuse et illégale culture, mais totalement inefficace puisque les ours n’ont pas bougé lorsque cinq policiers sont arrivés sur les lieux.”Ils ont été apprivoisés. Ils étaient assis et regardaient. À un moment donné, l’un d’entre eux est monté sur le capot de la voiture de police, s’est assis un moment, puis est parti”, raconte le sergent de la Gendarmerie royale du Canada, Fred Mansveld.Très nombreux au Canada, les ours noirs vivent en général seuls, à l’exception des mères et de leurs petits. Une loi provinciale interdit de les nourrir, car comme le déplore David Webster, agent du ministère de l’Environnement de Colombie-Britannique, les alimenter représente une véritable “condamnation à mort” pour les ours.Domestiqués, ces animaux sauvages sont particulièrement dangereux. S’ils sont nourris, ils tentent de trouver d’autres humains et peuvent alors détruire des propriétés, ou plus rarement attaquer, voire tuer. C’est pourquoi des centaines d’ours sont abattus chaque année, “par bienveillance” assure Fred Mansveld.Le 20 août 2010 à 18:16 • Emmanuel Perrinlast_img read more

CO2 laviation sengage à plafonner ses émissions

first_imgCO2 : l’aviation s’engage à plafonner ses émissionsLes 190 pays membres de l’Organisation de l’aviation civile internationale (OACI) ont adopté le 8 octobre, lors de l’assemblée générale de l’organisation à Montréal, une résolution par laquelle ils s’engagent à tenter de plafonner les émissions de CO2 dues à l’aviation à partir de 2020.”Sans aucune attribution d’obligations particulières aux États, l’OACI et ses États membres, ainsi que les organisations compétentes, travailleront de concert pour s’efforcer de réaliser à moyen terme un objectif ambitieux collectif consistant à maintenir les émissions nettes mondiales de carbone provenant de l’aviation internationale au même niveau à partir de 2020″, lit-on dans le texte adopté vendredi à Montréal.S’il ne constitue pas un engagement ferme et définitif, il est considéré comme un “accord historique” faisant de l’OACI “la première institution des Nations unies à amener un secteur à mettre en place un accord harmonisé à l’échelle mondiale en vue de réduire ses émissions de CO2”.L’organisation vise également avec cette résolution l’objectif mondial d’une amélioration annuelle de 2% du rendement du carburant jusqu’en 2050 et la mise en place d’un cadre mondial pour le développement et la généralisation de carburants de remplacement durables, fixant l’échéance à 2013 pour la mise en place d’une norme sur les émissions des moteurs d’aviation.À lire aussiComment le climat pourrait être perturbé par le minuscule plancton arctiqueLe document souligne toutefois qu’il appartient aux États de se fixer des objectifs plus ambitieux, qui pourraient permettre de compenser la croissance du transport aérien des pays en développement. C’est notamment le cas des membres de l’Union européenne, qui se sont engagés à réduire le niveau de leurs émissions de 10% par rapport à celui atteint en 2005, et ce à l’horizon 2020.Par ailleurs, l’OACI reconnaît le système communautaire d’échange de quotas d’émission (ETS), une taxe visant les émissions des vols partant et à destination de l’Europe, qui doit entrer en vigueur en 2012. Une reconnaissance de grande importance au vu des actions en justice lancées contre ce système par des compagnies aériennes américaines.Le 15 octobre 2010 à 18:25 • Emmanuel Perrinlast_img read more

Hayabusa la sonde a bien rapporté des particules dastéroïde

first_imgHayabusa : la sonde a bien rapporté des particules d’astéroïdeAprès des mois de suspense intenable pour les chercheurs de l’agence d’exploration spatiale japonaise (Jaxa), cette dernière vient d’annoncer la présence de quelque 1.500 particules d’astéroïde dans les échantillons rapportés par la sonde Hayabusa. Dans un communiqué, la Jaxa annonce : “Après analyse de poussières présentes dans la collecte, nous avons constaté que presque toutes étaient extraterrestres et avons abouti à la conclusion qu’il s’agissait de particules provenant de l’astéroïde Itokawa”, celui-ci étant vieux de plusieurs dizaines à plusieurs centaines de millions d’années. La confirmation de cette nouvelle est d’autant plus importante qu’il s’agit des toutes premières matières d’un corps céleste autre que la Lune à avoir été rapportées sur Terre.

L’exploitation de technologies spéciales s’avère donc nécessaire pour permettre des analyses plus poussées. “Nous espérons qu’en poursuivant les analyses des poussières d’Itokawa, nous apporterons une nouvelle contribution à la compréhension de l’origine du système solaire”, s’enthousiasme l’agence japonaise.La capsule de la sonde Hayabusa contenant ces précieux échantillons avait été récupérée en juin dernier dans le désert australien, après avoir effectué en sept ans, un périlleux voyage dans l’espace de quelque six milliards de kilomètres. Elle avait alors été confiée au centre de recherche de Sagamihara, situé à Kanagawa, à l’ouest de Tokyo.Le 17 novembre 2010 à 09:43 • Emmanuel Perrinlast_img read more
