    At it's root, David Cameron??s vision of the Big Society is about two things. As well as empowering communities to take more of the decisions and run more of the activities that affect their lives, it encourages individuals to accept the responsibilities that this new power brings. This is a vision that the professional engineering community should welcome and should play their part in making a reality. View full abstract»

    Explaining the importance of the UK Bribery Act when official Government Guidance to the new legislation was published recently, Business Secretary Vince Cable said: ??Bribery has no place in British business, at home or abroad. This new robust law reflects the UK??s leading role in the fight against bribery, updates regulation dating back to 1906 and paves the way for competitive but fair practice.?? View full abstract»

    Just as nations worldwide had accepted nuclear power was key to tackling climate change, nuclear disaster struck. What went wrong at the Fukushima Daiichi plant? The crisis was principally a result of flooding. When the earthquake hit, the three nuclear reactors operating at the plant did exactly as they were designed to do: they shut down. With off-site power wiped out, emergency diesel-generators kicked in and started pumping cooling water to the fuel rods in each reactor. These cooling systems, designed to keep reactor containment vessel temperatures to around 260??C, operated exactly as they should ?? until one hour later when the tsunami swept through.

    The public perception of nuclear energy has taken a battering in the wake of the Fukushima nuclear accident. It had been a painfully sluggish process, but since the nightmare scenario of a complete meltdown of a nuclear plant 25 years ago at Chernobyl, the public had, inch by inch, been creeping towards a grudging acceptance of a nuclear future.

    Some of the world's most extensive sea defences did little to protect Japan's coast from the devastating tsunami so is it time to develop buildings that can withstand the impact when it comes?The Japanese government has invested heavily In seawalls and breakwaters, which stretch along some 40 per cent of the country's 30,000km coastline. The policy reflects a general belief by authorities in tsunami prone regions around the world that concrete barriers offer the best hope of protection from the sea. Indeed. that may be true for smaller storms, but the disaster in Japan illustrates that seawalls offer precious little protection against the most ferocious tsunamis. Many coastal engineers are now calling for a shift in policy. Rather than trying to keep the sea out by building ever higher walls, more lives might be saved by designing buildings that can withstand the waves - an a research that up to now has received little funding.

  • Robots to the rescue?

    The use of robots in disaster zones was developed in response to the Hanshin-Awajii Earthquake in Kobe, Japan and the attacks on the Murrah Federal Building in Oklahoma City in the United States. These events of the mid-1990s encouraged a number of researchers to think about the applications of robots for critical emergency crises. Since that time, search and rescue robots have been used to help the rescue crew efforts of the World Trade Center (2001). Unmanned ground vehicles helped with the rescue effort when terrorists crashed planes into the Twin Towers and around 3,000 people were killed. View full abstract»
