Con motivo de la velocidad alcanzada... les invitamos el miércoles 4 de julio a partir de las 21 horas al teatro tradicional de marionetas con sombras de Indonesia: A través de la historia de Arjuna Tapa del Mahabaratta y con las marionetas balinesas originales hará una introducción a este mundo mágico donde se mezclan las dos caras de la realidad; la de aquí y la de ahí, la que se ve y la que no, lo que uno piensa que es y lo que realmente es, lo bueno y lo malo, lo de arriba y lo de abajo, la luz y la oscuridad, lo sagrado y lo profano, lo tradicional y la actualidad, la artesanía y la tecnología. Antonio Muñoz von Furstenberg tuvo la oportunidad de aprender el arte del Wayang Kulit, durante su estancia en Bali en 2011, de manos del maestro dalang I Nyoman Sumandhi. Hijo y nieto de maestros marionetistas, director del High School of Performance Arts de Denpasar, Bali hasta 1999. Sumandhi ha impartido sus conocimientos y actuado en Estados Unidos, Europa y Asia.

5 Easy to Grow Mosquito-Repelling Plants As the outdoor season approaches, many homeowners and outdoor enthusiasts look for ways to control mosquitoes. With all the publicity about the West Nile virus, mosquito repelling products are gaining in popularity. But many commercial insect repellents contain from 5% to 25% DEET. There are concerns about the potential toxic effects of DEET, especially when used by children. Children who absorb high amounts of DEET through insect repellents have developed seizures, slurred speech, hypotension and bradycardia. There are new DEET-free mosquito repellents on the market today which offer some relief to those venturing outdoors in mosquito season.

Bicycle Maintenance Guide and Riding Tips This page was last updated 24 May 2007. I often get asked about bicycle maintenance and repairs, and tips for how to ride efficiently. This little manual is intended as a summary of what I have learned over the years. I am not a professional mechanic. All of what I say here is the result of personal experience and opinion and may in places flatly contradict professional techniques, but it has served me well. I offer no guarantees that it will work for you. Metal Alloy Purifies Water and Generates Electricity At last, little chunks of aluminum everywhere can be something greater then a soda can or a baseball bat. Thanks to a special reactive alloy, some of those lucky little nuggets could solve the world's energy crisis. Jerry Woodall, an engineer at Purdue University, has created an aluminum alloy that reacts with water to create hydrogen and heat. He is encouraging venture capitalists to design a system that uses both capturing the hydrogen as fuel and using the heat to pull clean water out of the air. The greatest benefit of using aluminum is its abundance.

Australian Engineers Unveil "Free Energy Machine" THE world may soon be able to buy one of the Far North's most controversial yet revolutionary inventions. The Lutec 1000 free energy machine have resurfaced after six years of steering clear of the public spotlight, having been granted patents in at least 60 countries around the world, including the US, China and India. Engineers John Christie and Lou Brits, who have endured intense criticism after they first unveiled their invention in 2001, are now preparing to construct a prototype of their revolutionary power device they hope to market within the next two years. The dynamic duo said they felt somewhat vindicated they had been able to land patents for their device and have had the Lutec verified by an independent engineer. "When we first kicked off, there was a huge fuss about it and people said we’d never get patents for it," Mr Christie said. "They said it would never work, so we couldn’t get patents, so it’s a good thing to see now."

Wild China: 25 Spectacular Species You Should See China is certainly one of the most beautiful places on earth. Entwined with temples of culture, mountains painted in white snow, lands of the giant panda, coastlines enriched with amazing colonies of unusual birds, dense forests that are roped with hunting tigers and a great wall that stretches through the land and ripples with history. These are only a small handful of the treasures that embellish Chinese lands. Maize-breeding records could drive breeding programmes [BEIJING] Genetic changes in maize introduced through artificial selection could serve as important reference points for future molecular-based breeding programmes, according to researchers in China. Since its first cultivation in Mexico around 10,000 years ago, maize has become one of the world's most widely-produced crops. Throughout that time, farmers, and more recently scientists, have used breeding techniques to improve yields and modify crop tolerance to external factors such as drought and high salinity levels. To better understand the genetic changes associated with crop-breeding, scientists at the Chinese Agricultural University (CAU) in Beijing sampled 278 inbred maize lines and published their findings earlier this month (3 June) in Nature Genetics. Genetic re-sequencing revealed a steady decline in nucleotide diversity – the range of variation within a single species – during that period.

Corn Ethanol Worsens Gulf of Mexico 'Dead Zone' photo by tlindenbaum It's almost considered conventional wisdom at this point that corn ethanol probably isn't the best biofuel out there. It may not be the primary cause of global food shortages, but corn-based ethanol has nevertheless has gotten a bad rap lately. Here's something that won't change that tarnished reputation: Moving Wind Turbines in a New Direction Recently, CleanTechies had the pleasure to speak with Phillip Ridings, CEO of Dragonfly Industries, Inc. We talked about the the company, its products, and what its products may mean for the clean tech sector. If Dragonfly lives up to it’s reputation it could easily revolutionize the wind industry. CleanTechies: Phillip, can you tell us a little about the designs for the Dragonfly Turbine and MantaRay Power stations and what kind of plans you have for their future? Phillip: Dragonfly is our land based wind turbine and MantaRay is our new water turbine so we can build one of the first Off Shore Power Stations! This product was conceived after the oil spill in the gulf.

Revealed: The stunning images which show how Europe wastes energy and pollutes light while Africa, South America and much of Asia is in darkness By Craig Mackenzie Published: 12:15 GMT, 8 July 2012 | Updated: 06:51 GMT, 9 July 2012 At night, London is a burning bright spot, consuming enough energy to power Ireland with its light show. But as these stunning images from space show, we in the West are guilty of wasting energy and polluting light on a staggering scale.

Snowflakes Up Close: A Small, Fragile World If you’re one of those people who likes to ponder things while looking out a frosty window on a cold winter day, these pictures will clear up one of those long standing wonders: each snowflake really IS unique. Some look like roman columns, others circuit boards or spaceships. Taken under high magnification using a microscope, these images bring a fragile and beautiful world into view.
