Pile Dynamics has recently announced the release of a new model of Pile Driving Analyzer® (PDA) System, the PDA-8G, billing it as the culmination of a complete redesign effort of the most widely employed system for Dynamic Load Tests of any type of deep foundation. Like previous PDAs, this 8th generation model performs the test normalized by the American Society of Testing and Materials standard ASTM D4945. The test, which for many decades has been accepted as an alternative for static load tests in more than 100 countries around the world, takes place either during pile driving or when a substantial mass impacts a non-driven pile. At each impact the Pile Driving Analyzer takes data obtained by sensors attached to the pile and calculates bearing capacity and other quantities.
An animation was released last week showing what a ride on the world’s tallest roller coaster will feel like. The 570-foot roller coaster called “Skyscraper” will be built in Orlando, Florida and will open in 2017. It was designed by Orlando-based architectural firm HHCP and will be built by Eufforia. The “Skyscraper” will be built on top of a new 495,000 square-foot shopping and entertainment complex on Orlando’s International Drive. Once completed, the roller coaster will overtake the 465-foot tall Kingda Ka at Six Flags Great Adventure in Jackson, New Jersey as the world’s tallest roller coaster. Construction is set to begin early next year and take two years to complete.
Millions of years ago, the sloping ground of southwest Utah was frequently covered with ash and debris, as a result of the intense volcanic activity taking place in the area. Those ash and debris layers were deposited on top of deeper deposits of hardened ash, which after eroding into slippery clay, set the ground for what now scientists believe was the world's largest landslide, covering an area nearly 39 times the size of Manhattan!
While Philae's landing attempts are still under progress, a set of 10 high end instruments will significantly contribute to the understanding of the comet's composition, in a way that was never possible before.
Switzerland and northern Italy are severely battered by heavy rain in the last days, which caused extensive landslides and cost several lives. Weather forecasts predict that rain will continue to hit the area for the next 24 - 36 hours, leading both countries to issue major flood alerts.
The European Space Agency made history yesterday by successfully landing Philae to Comet 67P. Philae was carried by the Roseta spacecraft that traveled for more than 10 years until it reached its destination. Philae successfully landed on the surface of the comet, but, according to the latest information available, it has not been able to attach itself to the comet and is running a risk of detaching from the comet’s surface. It still transmits truly unique data from the surface of the comet.
London’s Tower Bridge has just joined the Grand Canyon, Willis Tower, and the Eifel Tower by opening a glass walkway 120 feet above the bridge deck. The walkway is the first of two walkways to open over the bridge that will allow visitors to experience vertigo inducing views of the Thames River. The other walkway, over the east side of the bridge, will be opened on December 1.
