A new artificial surface inspired by floating seeds, which could provide an alternative to the toxic paints currently used to prevent fouling on ship hulls, has been developed by German scientists. Scientists from the Biomimetics-Innovation-Centre have developed a new anti-fouling surface based on a seed from a species of palm tree. "These plants have seeds which are dispersed by the ocean currents. As it is an advantage for these seeds to remain free of fouling to allow them to disperse...

Ship owners need accurate scientific data to support intelligent decisions on coating systems and hull cleaning intervals. MACSEA now offers an independent hull monitoring service designed to save fuel and reduce emissions by detecting the early onset of hull fouling. Stonington, CT. (PRWEB) April 06, 2011 Ship owners, ship operators, and ship managers realize that hull fouling causes drag-related speed loss and increased fuel consumption when more power is delivered in order to maintain...

It may seem illogical, but boiling is a very efficient way to cool engineering components and systems used in the extreme environments of space. An experiment to gain a basic understanding of this phenomena launched to the International Space Station on space shuttle Discovery Feb. 24. The Nucleate Pool Boiling Experiment, or NPBX, is one of two experiments in the new Boiling eXperiment Facility, or BXF. Nucleate boiling is bubble growth from a heated surface and the subsequent detachment of...

Geophysical phenomena such as the dynamics of the atmosphere and ocean circulation are typically modeled mathematically by tracking the motion of air or water particles. These mathematical models define velocity fields that, given (i) a position in three-dimensional space and (ii) a time instant, provide a speed and direction for a particle at that position and time instant. "Geophysical phenomena are still not fully understood, especially in turbulent regimes," explains Gary Froyland at the...

Floods cut down more bridges than fire, wind, earthquakes, deterioration, overloads and collisions combined, costing lives and hundreds of millions of dollars in damage. The speed and turbulence of an overflowing stream scours away the river bottom that provides the support for a bridge foundation, causing more than 60 percent of bridge failures in the U.S. in the last 30 years. Currently, "there is no way to determine risk during these crucial events," said Xiong "Bill" Yu, an assistant...

An understanding of particle diffusion in the presence of constrictions is essential in fields as diverse as drug delivery, cellular biology, nanotechnology, materials engineering, and spread of pollutants in the soil. When a driving force is applied, displacement of particles occurs as well as diffusion. A paper in the Journal of Chemical Physics, which is published by the American Institute of Physics (AIP), quantifies the effects of periodic constrictions on drift and diffusion in systems...

To lower the fuel consumption of airplanes and ships, it is necessary to reduce their flow resistance, or drag. An innovative paint system makes this possible. This not only lowers costs, it also reduces CO2 emissions. The inspiration "“ and model "“ for the paint"Ëœs structure comes from nature: The scales of fast-swimming sharks have evolved in a manner that significantly diminishes drag, or their resistance to the flow of currents. The challenge was to apply this...

Not only in the Earth's mantle, in the atmosphere and in the outer layers of the Sun, but also in a chemical reactor, the exchange of heat may not be as effective as originally thought. There, because warm fluid rises and hence induces movement, the turbulent convection can be 100 billion times stronger than in the typical cooking pot. Hot fluids mix turbulently with warm fluids. As the temperature difference between the cold and warm sides increases, the heat transport increases...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
