Over or Under E-Waste Info - TECHNOLOGY FOR PEOPLE GROUP INC. What is e-Waste? E-waste (electronic waste) includes computers, entertainment electronics, mobile phones and other items that have been discarded by their original users. While there is no generally accepted definition of e-waste, in most cases e-waste consists of expensive and more or less durable products used for data processing, telecommunications or entertainment in private households and businesses. Why is e-waste a problem? E-waste is both valuable as source for secondary raw material, and toxic if treated and discarded improperly. Due to lower environmental standards and working conditions in China and India, e-waste is being sent to these countries for processing – in most cases illegally. E-waste is of concern largely due to the toxicity of some of the substances if processed improperly. E-waste presents difficulties for recycling due to the complexity of each item and lack of viable recycling systems. Health hazards in E-waste Personal Computers (PCs)

- StumbleUpon Cover Story Juan comes up to the Mexican border on his bicycle. He's got two large bags over his shoulders. The guard stops him and says, "What's in the bags?" "Sand," answered Juan. The guard says, "We'll just see about that get off the bike." The guard takes the bags and rips them apart; he empties them out and finds nothing in them but sand.

SO DANGEROUS, THAT I AM FORCED TO SAY DO NOT TRY THIS TWICE, AND IN ALL CAPITAL LETTERS. Sparks. So, what's happening here? The two sides of the grape act as focal points for the microwaves (the waves themselves, not the appliance). And one spark is all you need. Why is the plasma in the video above so large? The glass contains the air around the grape even more so than the microwave oven, thereby concentrating the plasma, and allowing for the light show seen in the video (as well as protecting the roof of the microwave). Bonus fact: Ivory soap does something neat when microwave as well -- as seen here.

Fix the planet The problem with e-waste ¶ What is e-waste? ¶ Many people don't know that electronics have all kinds of nasty chemicals in them. For example, the glass in a typical CRT has about ten pounds of lead in it. What happens to e-waste? To recycle electronics properly, you must carefully disassemble them and separate out each type of material. Why? From UNEP/GRID-Arendal Maps and Graphics Library But labor is cheap in the developing world. The United Nations Environmental program explains this process: "In many countries entire communities, including children, earn their livelihoods by scavenging metals, glass and plastic from old computers. How you can save the planet ¶ Use devices as long as possible ¶ Maintaining and repairing devices dramatically improves their usable lifespan. You have a responsibility to humanity to keep things working as long as possible and to dispose of them properly. Join the crusade ¶ There is a finite quantity of resources on this planet.

Learning to Communicate Without Fear & Tao of Unfear As part of my study of eastern philosophy, I took a class on meditation. The focus of the class, unlike zazen, was on a headier, more thought-filled meditation. As a component of that class, one of our sessions was on studying non-violent communication. I’ve been meaning to write on the subject of communication for some time, since it was the subject of the philosophy thesis I had planned. It wasn’t until the other night, when I totally botched an attempt to discuss a problem with a friend, that I realized how rusty I’d become. The point of this post is not to teach you how to overcome social anxiety—that is another beast entirely—but is, instead, intended to help you speak honestly, respectfully, and without punishment toward the people you’re already speaking to. Who’s right? Do you ever feel better when you win an argument? …Calm and repose are what he prizes; victory (by force of arms) is to him undesirable. If we win, someone necessarily loses. You make me feel… No I don’t!

Recycling Gone Bad: Where Does Our High Tech Waste Go? Where do our discarded computers, monitors, keyboards, inkjet cartridges, toner cartridges and printers go? Ideally, they should all be recycled and the materials should find their way back into the new products. However, what really happens is that about 80 percent of electronic waste gets exported to the Third World countries where it turns into an environmental nightmare. One such place importing electronic waste is Guiyu, China shown in this picture taken by Behring-Chishlom from Greenpeace. China has banned such imports, but the ban is not enforced. "Heaps of empty cartridges line the streets and riversides after being scavenged only for their toner. of recycling and dumping practice has rendered local drinking water not potable; the river has 200 times acceptable levels of acid and 2,400 times acceptable levels of lead. Why do recycling companies send the waste to such places instead of actually recycling it?

Female Bodybuilders (Video) The Pen Is Mightier Than The Phone: A Case for Writing Things Out There’s all kinds of advice across the web about when to use which app for each small thing that needs doing. But the advocates for using paper to complete certain tasks are not so loud (you can’t hear them typing, among other things). Yet a Forrester Research survey of business professionals found that 87 percent of them supplement gadgets with paper productivity, and 47 percent thought their personal and company efficiency would improve with better note-taking. The survey might have been biased, since it was sponsored by the makers of the Livescribe smart pen, but you can’t help but think it touches on a need to refamiliarize ourselves with ink and thinly sliced wood pulp. Paper, but more specifically handwriting, will likely always be with us, and that’s a good thing. It’s a smoother path from your brain to the printed word, it saves you from task-switching overload, and it possibly makes the best to-do list.

Face transplant patient ready to go home Dallas Wiens, 26, lost much of his face after an accident. He received a new face in a landmark transplant operation. Dallas Wiens became the first full-face transplant patient in the United StatesHis doctors didn't think he'd survive the burn injuries from an accidentHe can smell again, and doctors say his speech will probably improve, too (CNN) -- Dallas Wiens wanted to feel his 4-year-old daughter's kisses again, something he couldn't do after a horrific electrical accident disfigured his face. But he'll be able to sense her touch again soon, doctors said Monday, less than two months after Wiens underwent the first full face transplant in the U.S. In the meantime, Wiens already has little Scarlette's seal of approval. Wiens' experience represents a new frontier for reconstructive surgery, said Dr. For 90 days, doctors kept him in a medically induced coma while they performed surgeries and he breathed through a ventilator. But he did survive. Full-face transplant recipient speaks

End the Dumping of e-Waste into the Developing World | Allen Hershkowitz The New York Times Magazine published a photo essay titled “Dumping Across the Digital Divide” this week, which documents the dumping and hazardous management of electronic waste in Ghana. ( )This practice is not limited to Ghana and infects many other developing countries including China, India and Pakistan. As NRDC’s representative to the United Nations Basel Convention on the Transboundary Movement of Hazardous Waste in the late 1980s, a treaty that was intended to end the dumping of hazardous wastes by industrialized countries into the developing world, I have watched with disappointment for almost two decades as the United States stands virtually alone in the world in not ratifying that treaty. Self-interested firms who export e-waste to the developing world misleadingly argue that this is a “Free Trade” issue.
