Bully (2011 film) Bully (originally titled The Bully Project) is a 2011 documentary film about bullying in U.S. schools. Directed by Lee Hirsch, the film follows the lives of five students who face bullying on a daily basis. Bully premiered at the 2011 Tribeca Film Festival.[2][3] It was also screened at the Hot Docs Canadian International Documentary Festival[4] and the LA Film Festival.[5] Bully had its global premiere at Italy's Ischia Film Festival on July 17, 2011.[6] Bully was acquired by The Weinstein Company immediately after its premiere at Tribeca Film Festival.[7] The film was released in United States theaters on March 30, 2012.[8] On the official website the filmmakers are promoting Bully as an important advocacy tool against bullying and in facilitating an anti-bullying movement.[9] Contrary to the filmmaker's goals, the film suffered from a lack of accessibility in theatres due to MPAA rating controversy and from an extended downtime between theatre and home release.

Ondes ELF extremely low frequency Un article de Wikipédia, l'encyclopédie libre. L’extrêmement basse fréquence (ou ELF, extremely low frequency en anglais) est la bande de radiofréquences comprise entre 3 et 30 Hz (longueur d'onde de 100 000 à 10 000 km). Alors que la bande supérieure 30 à 300 Hz sert aux liaisons sous-marines, cette bande n'est pas utilisée en télécommunications, mais sert à détecter certains phénomènes naturels, générateurs d'impulsions radioélectriques. Ondes ELF naturelles[modifier | modifier le code] Des ondes ELF naturelles sont présentes sur Terre, créées par les éclairs de foudre qui déclenchent l’oscillation des électrons de l’atmosphère. Enfin des émissions ELF de puissance énorme, de l’ordre de 100 000 fois l’énergie lumineuse du soleil, sont théoriquement émis par une forme de pulsars appelés magnétars. Impacts sanitaires ? De tels champs peuvent être développés par les lignes à haute-tension[3] ou les gros transformateurs. Sources[modifier | modifier le code] Infrason

Cooling on Warming By Andrew Rugg Nick Schulz and Ken Green snickered back and forth this week about a new study in Public Opinion Quarterly, which looked at the different results produced by survey questions using the terms “global warming” and “climate change.” The study concludes that Republicans are less likely to believe global climate change is real when questions use the term “global warming” as opposed to “climate change.” Other surveys have made a similar point about partisan differences on the causes of global warming/climate change. As the Pew Research Center pointed out in 2009: Two-thirds of Republicans (67%) say either that the earth is getting warmer mostly because of natural changes in the atmosphere (43%) or that there is no solid evidence the earth is getting warmer (24%). The authors of the Public Opinion Quarterly article, Jonathan Schuldt, Sara Konrath, and Norbert Schwarz, write that their observations “reflect associative differences between the terms . . .

FranceSIRTA unique observatoire atmosphère "Decorated" nanowires could lead to better batteries and solar cells Higher-density batteries, more efficient thin-film solar cells, and better catalysts may all soon be possible, thanks to a new technique that allows nanowires to be “decorated” with nanoparticles. Using the novel technology, scientists from Stanford University have been able to festoon the outside surfaces of nanowires with intricate chains of metal oxide or noble metal nanoparticles, thereby drastically boosting the effective surface area of the nanowires. Other researchers have previously tried to achieve the same end result, but apparently never with such success. “You can think of it like a tree. The nanowires are the trunk, very good at transporting electrons, like sap, but limited in surface area,” said assistant professor of mechanical engineering Xiaolin Zheng, who led the research. In prior attempts by other groups, the nanoparticle coatings were reportedly too thick – the nanowires essentially just ended up being wider, without much in the way of extra surface area.

ACSEIPICA Association Citoyenne Two degrees is out of reach | Mark Lynas This is the worrying news coming from the latest-generation of climate modelling efforts, just published in Geophysical Research Letters (abstract) by a Canadian team of scientists. The team use an Earth system model, fired up with a new generation of carbon emissions scenarios, to conclude that even limiting the 2100 temperature rise to 2.3C above pre-industrial would require “an immediate and rapid ramp down of emissions, followed by negative emissions (sequestration) in the later half of this century”. As for the goal of holding “the increase in global average temperature below 2C above pre-industrial levels”, well, to get onto that trajectory we would have to take global emissions “down to zero immediately”, because the allowable cumulative carbon budget associated with that temperature target has already been emitted. Can we come back to this in four years? One of the ideas of the ‘review’ is to take into account input from the IPCC’s fifth assessment report, due out early in 2015.

FinesParticules Ile-de-France temps réel Les particules fines dont le diamètre aérodynamique est inférieur ou égal à 2,5 microns (PM2.5) - potentiellement les plus toxiques - représentent un problème majeur de santé publique en Ile-de-France. Plusieurs millions de Franciliens sont ainsi exposés chaque année à un air qui ne respecte pas les réglementations européennes2. Le Laboratoire des sciences du climat et de l'environnement (CNRS-CEA-UVSQ) met en œuvre depuis plusieurs années un suivi systématique de la composition chimique des particules fines en Ile-de-France. Ce suivi est réalisé sur le « supersite » atmosphérique Sirta de l'Institut Pierre-Simon Laplace, situé sur le Plateau de Saclay ( à 20 km au sud-ouest de Paris. Ce site est aujourd'hui la seule station française de surveillance de l'atmosphère capable de rendre compte en temps réel des niveaux de pollution ambiante et de la nature chimique des particules.

Radiator Labs transforms radiators into energy-efficient heaters Its idea may be simple, but that did not stop Radiator Labs winning the MIT Clean Energy Prize with its controllable box that can be retrofitted to radiators to boost the efficiency of hot water and steam heating systems. The heavily insulated housings physically cover the radiator, trapping heat in the system, and strictly controlling the amount that is let into the room. This prevents homes becoming over-heated, and wasteful heat loss as people open windows to compensate. The controlled heat transfer is activated by a fan, which, thanks to the inclusion of wireless control technology, opens up all kinds of smart-home intelligent, remote and automated control sorcery. Of course, radiators fitted with valves can be turned down or off when heat isn't desirable, so Radiator Labs' system is arguably surplus to requirements in the majority of cases - provided people actually turn radiators or thermostats down when temperatures become too high rather than opening windows.

Noynoyism and the 3 basic problems Trending topics are now competing with militant slogans in captivating social consciousness. Social media is a new arena of ideological struggle. MANILA, Philippines - If Benigno Aquino Jr ended up toppling the dictator, could it have been possible for Left-leaning activists to coin the word "Ninoying" in the event he failed to fulfill their expectations? It is inconceivable. As far as the activists and revolutionaries at the time are concerned, it was the era of "isms," the 3 basic societal problems: imperialism, feudalism, bureaucrat capitalism. To introduce another term to describe a basic social ill would be to tread the path of revisionism, a betrayal of ideology. And if debates would ensue, they were conducted in plenums and "collectives" lasting until the wee hours of the morning -- long and winding, even bitter and deadly, but still highly polemical. RA vs RJ Recently, remnants of an old Left debate seemed to resurrect on the Internet. 1. 2. 3. Affirming Noynoy "Yakyaktivists"
