The results are significant because they can help to improve our understanding of medical conditions, such as thrombosis, aneurysms and arteriosclerosis. The research team is publishing its results in Physical Review Letters and the American Physical Society has highlighted the work on its Physics website, placing it on the Focus List of important physics news. Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically....
WASHINGTON, Feb. 14, 2013 /PRNewswire-USNewswire/ -- The Balloon Council, a national trade organization of balloon manufacturers, wholesalers, distributors and retailers, applauded Congress for making progress toward preventing a shutdown of the Federal Helium Reserve, which would severely impact the helium market and disrupt the helium supply chain nationwide. The Balloon Council released its statement at the House Natural Resources Committee Oversight Hearing held today on "The...
SAN FRANCISCO, Feb. 13, 2013 /PRNewswire/ -- With Valentine's Day festivities taking place this week, many customers will celebrate with helium-filled metallic balloons. Pacific Gas and Electric Company (PG&E) urges customers to think safety first and securely tie a weight to all metallic balloons containing helium to prevent them from floating away. Metallic balloons that contact overhead power lines can disrupt electric service to an entire neighborhood, cause significant...
NASA NASA's Aqua satellite passed over Cyclone Gino as the storm continues to wind up in the southern Indian Ocean, consolidating and strengthening. Infrared data shows the storm has strengthened but it is headed for cooler waters which will weaken it in coming days. On Feb. 12 at 0841 UTC, NASA Atmospheric Infrared Sounder (AIRS) instrument that flies aboard the Aqua satellite captured infrared imagery of Cyclone Gino that showed the storm developed a large area of very cold, high...
DALLAS, Feb. 12, 2013 /PRNewswire-iReach/ -- The research report "Metering (Dosing/Chemical Injection) Pump Market, by Type (Diaphragm & Plunger/Piston) and Application (Water & Wastewater, Oil & Gas, Petrochemical, Chemical, Pharmaceutical, Food & Beverages, Pulp & Pater)- Global Trends & Forecasts to 2017" says Asia-Pacific, with its developing economies and rapidly expanding manufacturing bases, is expected to experience highest revenue growth during the...
NASA The fifteenth tropical cyclone of the Southern Indian Ocean season strengthened into a tropical storm today, Feb. 11, and NASA's Aqua satellite passed overhead hours after it reached tropical storm strength. Tropical Cyclone 15S was born from the low pressure area designated as System 92S. System 92S developed on Feb. 9 and intensified into a tropical storm on Feb. 11 at 0300 UTC. At that time, Tropical Cyclone 15S had maximum sustained winds near 35 knots (40.2 mph/64.8 kph),...

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...
