DENVER, Nov. 13 /PRNewswire/ -- Many have tried to develop new and unique forms of propulsion over the past 100 years and virtually all have been disproven. In 2006, however, Aries Propulsion Research Labs (APR Labs) introduced a new method of propulsion technology labeled Omni-Directional Propulsion ("ODP"). The method was created by designer Chris B. Hewatt and was first published on the United States Patent and Trade Organization (USPTO) Web site as publication 20060230847. Since its...
In award-winning demo, neuroscientists at USC and American University suggest curveballs do not breakThe answer to the question of whose curveball breaks harder -- that of the Yankees' A.J. Burnett or the Phillies' Cole Hamels -- may be neither.Zhong-Lin Lu, a professor of cognitive neuroscience at USC, along with USC alumni Emily Knight and Robert Ennis and Arthur Shapiro, associate professor of psychology at American University, developed a simple visual demo that suggests a curveball's...
PUNE, India, Oct. 12 /PRNewswire/ -- Suzlon Energy Limited (SEL), the world's third leading* and India's largest wind turbine manufacturer, announced the completion of its worldwide program to strengthen and reinforce all Suzlon blades of the V2 type on its S88 - 2.1 MW turbine fleet. Instances of blade cracks were first discovered in late 2007 during the operation of some of Suzlon's S88 wind turbines in the United States. Suzlon responded immediately and launched a detailed root cause...

Modeling the aerodynamic secrets of one of Nature's most efficient flyersResearchers are one step closer to creating a micro-aircraft that flies with the maneuverability and energy efficiency of an insect after decoding the aerodynamic secrets of insect flight.Dr John Young, from the University of New South Wales (UNSW) in Australia, and a team of animal flight researchers from Oxford University's Department of Zoology, used high-speed digital video cameras to film locusts in action in a wind...
A U.S. study shows not all insects have rigid wings, with some insects, such as moths, having wings that flex and deform during flight. University of Washington researchers said most scientists who study the mechanics and aerodynamics of insect flight have assumed insect wings are relatively rigid as they flap. But the researchers in the new study, led by biology Professor Thomas Daniel, used high-speed digital imaging to show some insects' wings flex and deform while in flight. The evidence...
Most scientists who create models trying to understand the mechanics and aerodynamics of insect flight have assumed that insect wings are relatively rigid as they flap.New University of Washington research using high-speed digital imaging shows that, at least for some insects, wings that flex and deform, something like what happens to a heavy beach towel when you snap it to get rid of the sand, are the best for staying aloft."The evidence indicates that flexible wings are producing...
In biomedicine and biotechnology the smallest, complex, compound sample quantities must be reliably processed. Microsystems with new mechanisms of action for pumping, filtering and separating will manage this task with great efficiency in the future.Providing reliable evidence of viruses in human blood presently requires time- and labor-intensive molecular-biological procedures. Established methods are particularly hard pushed to produce evidence when the viral burden is very low, for example...
GARDINER, N.Y., June 23 /PRNewswire/ -- "The Universal Properties of Acceleration: Did Einstein Look the Wrong Way?" (published by AuthorHouse) is about gravity. Author Barry Lebost proposes a new law in physics stating "that all acceleration and its intimate partner inertia have the same general properties everywhere in the universe including the surfaces of planets and stars." Lebost demonstrates that when universal property tests are performed upon the surface of planet Earth, the test...
Biomass, metabolic activity much lower than at previously explored sitesAn international oceanographic research expedition to the middle of the South Pacific Gyre "“ a site that is as far from continents as it is possible to go on Earth's surface "“ found so few organisms beneath the seafloor that it may be the least inhabited sediment ever explored for evidence of life.Yet since half of the world's ocean is composed of similar gyres, biomass and metabolic activity may be equally low in...

The boomerang is a flying tool, made of wood or carbon fiber-reinforced plastic, with a curved shape that is often used as a weapon or for sport. They have also been made of bones and come in many different shapes and sizes depending on their geographic or tribal origins and their intended function. The most commonly recognizable type is the returning boomerang which travels in an elliptical path and returns to its point of origin. The returning boomerang has lopsided wings in order to create...
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...
