Intech Corporation posits that based on the ability of Cast Nylon 12 to withstand the challenging conditions found in pulp and paper processing, Power-Core(tm) Gravity Cast Polyamide 12 also makes a natural fit for other types of mixers and processing machines. Closter, NJ (PRWEB) February 28, 2014 Most engineering polymers won’t stand up to the harsh conditions found inside the mixing tanks used in pulp and paper processes. High shear forces, elevated temperatures, aggressive chemicals...

Hurricanes Could Be Tamed By Offshore Wind Farms
2014-02-26 11:45:18

Brett Smith for redOrbit.com - Your Universe Online In addition to providing a renewable source of energy and reducing society’s carbon footprint, wind turbines may provide the added benefit of taming the power of a hurricane. According to a new study in the journal Nature Climate Change, thousands of offshore wind turbines could diminish hurricanes' wind speeds, wave heights and storm surge. "We found that when wind turbines are present, they slow down the outer rotation winds of...

New Hurricane Model Can More Accurately Predict Storm Path, Intensity
2014-02-26 07:15:48

Brett Smith for redOrbit.com - Your Universe Online When Hurricane Sandy slammed into southern New Jersey in October 2012, it had essentially confounded both the NOAA's Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF). Now, a new real-time hurricane analysis system being developed at Penn State University has been shown to accurately predict the track and intensity of the deadly storm. "For this particular study aircraft-based Doppler...

South African Researchers Debunk Two Climate Change Myths
2014-02-25 14:45:12

Brett Smith for redOrbit.com - Your Universe Online A new study from South African researchers has debunked the notion that there are more tropical cyclones taking place due to global warming – at least in the Southern Indian Ocean. Jennifer Fitchett, a PhD student at Witwatersrand University in Johannesburg, said better meteorology has probably fueled the idea of climate change developing more and more storms. “From 1940, there was a huge increase in observations because of...

Removes Static from Highly Charged Surfaces and High Speed Operations Toronto, Ontario (PRWEB) February 24, 2014 Dirt buildup is a problem in many types of production applications, especially where plastic, fiberglass or other materials that have a propensity to develop a static charge are used. It is even more difficult to remove particulate from high speed applications or from highly static charged surfaces. The Nex Flow™ Air Blade™ Ionizers have been popular for many years used...

A barometer is an instrument that measures atmospheric pressure. The barometer measures pressure exerted by the atmosphere using water, air, or mercury. Through measuring the pressure one can forecast short term weather changes. Evangelista Torricelli is credited with the invention of the barometer in 1643. However, Gasparo Berti unintentionally built a water barometer around the same time. Rene Descartes was also noted as describing an experiment to determine air pressure but there is no...

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
