Russian scientist, Andrew Kolmogorov’s theory of turbulence has been widely accepted as a basic tenet of fluid dynamic theory since its introduction in 1941. New research out of the University of California Santa Barbara (UCSB) is causing physicists to rethink turbulence.
Chances of a large magnitude earthquake in California are higher than previously estimated seven years ago. Scientists came up with the new prediction using a new model based on the latest research and seismological data.
A collaboration between researchers at the University of West England Bristol (UWE Bristol) and Oxfam, an international organization dedicated to fighting poverty, is proving that urine might be an invaluable source of electricity in refugee camps and other impoverished areas. For decades, utilities in developed countries have derived energy from the methane found wastewater, but in areas where such complex treatment schemes are not possible, simple solutions such as a “pee-power” toilet could offer an inexpensive and desperately needed source of energy.
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.
