Find OpenCourseWare with OCW Search Classroom 2.0 Novo carro elétrico tem autonomia de 1 mil quilómetros Um novo carro elétrico tem autonomia para rodar por "mais de 1 mil quilômetros" com uma única carga. O veículo chamado Quantino foi anunciado pela montadora NanoFlowcell no final de fevereiro, porém, trata-se ainda de um conceito. Não há previsão deste modelo chegar ao mercado. De acordo com a NanoFlowcell, o Quantino utiliza um sistema de baixa voltagem para conseguir mais autonomia de uso. "Esse tipo de sistema nos permite gerar níveis de potência de condução que antes pareciam impossíveis", segundo a montadora. O modelo mais potente da Tesla, o Model S P58D, tem alcance de 407 quilômetros e velocidade máxima de 250 km/h. Com dois tanques de 175 litros cada, o Quantino pode levar 350 litros de líquido iônico, sendo um com carga positiva e outro com carga negativa. "Esse conceito representa uma verdadeira alternativa para a mobilidade elétrica do futuro, com potência e alcance incríveis", informa a NanoFlowcell.
Climate change will see parts of cities under water - Robinson Many people living along the coast of cities could find their homes under water with even a moderate sea-level change, former president Mary Robinson has warned. The United Nations special envoy for climate change said it was predicted 200 million people could be climate displaced people by the end of the century. “And, if we are not careful, by 2050,” she said. “We are talking about the fact that an awful lot of people live on the coast in parts of cities will be under water if sea levels rise by even a fairly moderate amount. And the prediction with the 4-degree world will be three times that.” The former president said although the global goal was stay below 2 degrees, scientists had told her the earth was on course for 4 degrees over this time frame. Ms Robinson said families in the Pacific Islands were faced with a “real threat to their existence” because of climate change. “I see communities faced every day with the erosions of their gardens, of their walls,” she said.
TeachLearnTech ‘Tis the season and all, but it’s not really that kind of a story. Not that kind of epiphany. Or maybe it is. I guess it just depends on what’s important to you, and for some people “the” Epiphany is a big deal. And since teaching’s important to me, this story of two epiphanies is pretty important personally. Our story starts in now what is rapidly becoming last month. Coming from the music world, performance is second nature to me. In music, and other performance-based classes, the show’s the thing. The Wise Man’s Vision I’m fortunate in that for my teaching career I worked with two good principals. Anyway, Barry used to observe my class, as principals are wont to do, and would talk to me afterwards and say things like, “You do such a good job of going from whole-class instruction, to small-group instruction, to individualized instruction. “No,” he would argue, humoring me, “it’s more than that.” Away on Yonder Star I say that often, but I finally have the proof to justify it.
Saylor.org – Free Online Courses Built by Professors Online Computer Science Courses In its purest form, computer science is the research and development of technology that solves specific problems. Computer science has brought the world smart phones, GPS systems, the gaming industry and tablet computing, along with technological developments that assist government, industry and medicine. In addition to creating new technology, computer scientists also make improvements to existing technology and study the ways computers can make our lives easier. One can learn more about this field of study through several online computer science courses. As with any branch of science, computer scientists perform research that establishes new information. Most computer scientists work on a theoretical level, using technology to study technology. Undergraduate degree programs in computer science require mathematics, physics and engineering classwork. During the first two years of a standard 4-year program, students focus on the basics: Hardware refers to the machinery of computers.
