Nuclear detonations caught the world's attention this summer when India and Pakistan tested their potential strength. To monitor the Comprehensive Nuclear-Test-Ban-Treaty, scientists at the Department of Energy's Pacific Northwest National Laboratory (Richland, WA) developed two devices for detect nuclear detonations. The Automated Radioxenon Sampler/Analyzer (ARSA) and the Radionuclide Aerosol Sampler/Analyzer (RASA) inspect the atmosphere for traces of radioactive material. Once activated, the systems will be located around the globe as an international monitoring system. ARSA analyzes air samples for radioactive xenon or radioxenon that seeps from underground nuclear explosions. The system collects air samples and processes them to trap the radioactive xenon on cold charcoal. RASA detects fission products from atmospheric explosions. It daily filters a huge volume of air to check for evidence of fission products from a nuclear explosion that attach to dust particles. Information collected by the ARSA, RASA, and other monitoring systems at the global stations will be passed on to an international data center. Call (202) 586-5806.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
