Iran’s Smart Concrete Can Cope With Earthquakes and Bombs

0


PolygamousRanchKid writes "Iran is an earthquake zone, so its engineers have developed some of the toughest building materials in the world. Ultra-high performance concrete (UHPC) could also be used to protect hidden nuclear installations from the artificial equivalent of small earthquakes, namely bunker-busting bombs. UHPC is based—like its quotidian cousins—on sand and cement. In addition, though, it is doped with powdered quartz (the pure stuff, rather than the tainted variety that makes up most sand) and various reinforcing metals and fibers. UHPC can withstand more compression than other forms of concrete. UHPC is also more flexible and durable than conventional concrete. It can therefore be used to make lighter and more slender structures. All of which is fine and dandy for safer dams and better sewers, which threaten no one. But UHPC's potential military applications are more intriguing—and for many, more worrying. Deep bunkers can be tackled in other ways. America's Defense Threat Reduction Agency (DTRA) has looked at what is known in the jargon as functional defeat, in other words bombing their entrances shut or destroying their electrical systems with electromagnetic pulses. They are also working on active penetrators—bombs which can tunnel through hundreds of meters of earth, rock and concrete. Development work is also under way on esoteric devices such as robot snakes, carrying warheads, which can infiltrate via air ducts and cable runs."

AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands

0

In 2009-2010, AMD launched the entire 4 chip Evergreen series in 6 months. By previous standards this was a quick pace for a new design, especially since AMD had not previously attempted a 4 chip launch in such a manner. Now in 2012 AMD’s Southern Islands team is hard at work at wrapping up their own launch with new aspirations on quickness. Evergreen may have launched 4 chips in 6 months, but this month AMD will be completing the 3 chip Southern Islands launch in half the time – 3 chips in a mere 3 months.

To that end today AMD is taking the wraps off the final piece of the Southern Islands puzzle: Pitcairn. The middle child of the family, it will be the basis of AMD’s $250+ enthusiast segment Radeon HD 7800 series. We’ve seen AMD capture the high-end with the 7900 series and struggle to control the mainstream market with the 7700 series, but how does the 7800 series fare amidst AMD’s lead in deploying 28nm GPUs? Let’s find out.

World’s collide as Super Mario Bros and Portal become Mari0 (video)

0
Remember when the amalgamation of Super Mario Bros and a Portal gun seemed like the most amazing, yet impossibly lucid pipe dream? As it turns out, the cake named "Mari0" by developer-house Stabyourself actually wasn't a lie. But lest you thought this just a redo of Super Mario Bros with a skosh of Aperture science thrown in, you'd be oh-so-wrong. How's about four-player co-op, in addition to a level editor and a bevy of hilarious modes that'll put a new twist on an old favorite. And could it get any better than available for the sweet sweet price of free? If that's not a ringing endorsement, we don't know what is. If you're still reading this, we're unsure why you're still here -- get your game on at the source link below.

World's collide as Super Mario Bros and Portal become Mari0 (video) originally appeared on Engadget on Sun, 04 Mar 2012 23:58:00 EDT. Please see our terms for use of feeds.
