Scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory demonstrated the first direct observation of increased radiative forcing due to increased carbon dioxide levels in the atmosphere. This study, published in Nature , is the first to provide direct observational evidence linking rising carbon dioxide concentrations to the greenhouse effect.
Engineers at the Technical University of Munich (TUM) have come up with a way to prevent concrete spalling caused by excessive temperature built up during a tunnel fire. The new technology consists of fibers added in the concrete but the changes in concrete behavior remain still to be investigated.
With nearly 70,000 bridges requiring repair works across the U.S. and an estimated cost of $70 billion, Associate Professor's 3-D model aims in facilitating officials and transportation agencies to monitor the aging infrastructure more efficiently and prioritize the required repair works.
Michael Pollino, researcher from the Case Western Reserve University has recently published his findings on a new innovative technique that will allow buildings to rock during an earthquake and return to equilibrium at the end of shaking. Rocking technology is still in early development stages but Pollino as well as other researchers are warm supporters and aim in developing design standards for practicing engineers.
A new pioneering technique in steel castings fabrication provides enhanced earthquake resistance and allows implementation of unique architectural designs. The new technique, initially developed in Canada is currently applied in many construction projects across the country and the U.S.
"Earthquake. Earthquake. Shaking to begin in ...15 seconds". The particular message preceded by a siren is going to warn people in a group of trial public and private institutions of an imminent earthquake. The specialized software, developed by the Pacific Northwest Seismic Network, based in University of Washington, will be installed in their computers and is the first earthquake early warning system tested outside the research community in the region.
With half a million dollars spent to adress direct flooding costs in the U.S. in 2012, flood risk evaluation is still hard to perform, since not all contributing factors are recognized, frequently leading to questionable river basin management decisions. A new study by UC Santa Barbara focuses on the basic principles of flood hazard analysis, indicating that not accounting for channel capacity may result into misleading estimates of the flood susceptibility levels also affecting flood insurance premiums calculation.
