Searching for health information on the web? Be careful: A new study says that it's difficult for many people to accurately access and evaluate credible health information. (snip) A new study (news release, pdf report) by medical consumer advocate URAC and Consumer WebWatch details the problems consumers have finding credible health information, and provides recommendations to improve the situation. The study cites four primary problems with finding reliable health care information on the web. Two reasons have to do with the knowledge and skill of web users. Many consumers' ability to locate and evaluate health information online is hindered by...

Diesel power takes to air Racine firm races big competitors for breakthrough By RICK BARRETTrbarrett@journalsentinel.com Last Updated: Oct. 5, 2003 Racine - In an old airplane hangar once used by S.C.

ROLLS-ROYCE, the aeroengine manufacturer, is on course to win a £3 billion contract to refit the US fleet of B52 bombers. The company confirmed yesterday that it has put forward two plans for updating the engines of the aircraft after being approached by Boeing and the US Air Force. The B52s, which were used extensively in the Iraq war, are central to America’s bomber force but they are still powered by engines designed in the 1950s. The US Air Force has 85 in its active fleet and nine in reserve, each with eight engines. Analysts said the contract could be...

After Combustion:Detonation! At first glance, the engine bolted to the test stand looks like an unlikely candidate to lead an aerospace revolution. Its size is unimpressive: At about four feet long, it's dwarfed by the machinery that feeds it air and fuel, machinery that fills a house-size structure at the China Lake Naval Air Warfare Center in California. And its appearance is unremarkable: This machine has none of the grace of the high-bypass turbofans that power modern jetliners, with wide, sweeping inlets and delicate blades. From the outside, it's simply a collection of metal tubes, one large cylinder feeding into...

If there is anybody that knows anything about cars or knows of a good free website that will answer my question, could you chime in here?My problem: I have a 99 protege with 53000 miles on it, and the check engine light is on. I took it to one of those diagnostic centers about a week and a half ago, and they said they couldn't tell what was wrong with it, and they reset the light. They said it was probably nothing urgent, so don't worry unless it comes back on. Well of course, it came back on. The only...

I am posting this to inform everyone about how cars work, so they don't buy into scams about some product that claims to increase the gas mileage of a car. From the University of Wisconsin: Scientists have calculated the average amount of potential energy stored in various types of fuels used by humans as an energy source. Conversion factors: 1 gallon of fuel oil = 145,000 BTU 1 cubic foot of natural gas = 1,031 BTU 1 kilowatt hour of electricity = 3,412 BTU 1 cord of wood = 20,000,000 BTU 1 gallon gasoline = 125,000 BTU End quote As...

    Black hole theory suggests light is slowing   13:27 08 August 02 Hazel Muir   One of Einstein's most dearly held concepts - that the speed of light is constant - is looking a little fragile. Physicists in Australia claim there is good reason to think the speed of light has slowed over time. "Einstein would have absolutely hated this," said Paul Davies of Macquarie University in Sydney. "His entire theory of relativity was founded on the notion that the speed of light is an absolute fixed universal number." The physicists' suggestion follows earlier measurements of a key quantity called...

Master of Cylinders After 20 years of hibernation, engines that can shift on the fly from eight cylinders to four and back again are rumbling awake. On a recent ten-minute drive near a General Motors site in the stop-and-go suburbs of Pontiac, Mich., a prototype pickup truck switched from eight cylinders to four cylinders and back again--32 times. No one onboard noticed a thing. The truck held a new V-8 engine that shuts down four cylinders on the fly whenever they aren't needed. The aim: to improve fuel economy without sacrificing brawn. These engines boost gas mileage up to 25%,...

News ReleaseNASA Marshall Space Flight CenterHypersonics, In-Space Propulsion technologies on display in Oshkosh Experimental flight vehicles and high-flying aerial performances take center stage at the Experimental Aircraft Association's annual AirVenture Air Show, which is expected to draw more than 800,000 visitors to Oshkosh, Wis., July 23-29. At this year's 50th anniversary event, NASA's space transportation and propulsion teams will show off some experimental models and hardware of their own. And while they may not steal the show, in time they may steal the skies themselves.Marshall Center representatives will team with Glenn Research Center in Cleveland, Ohio; Langley Research Center in...

Monday, 29 July, 2002, 03:23 GMT 04:23 UK Boeing tries to defy gravity An anti-gravity device would revolutionise air travel Researchers at the world's largest aircraft maker, Boeing, are using the work of a controversial Russian scientist to try to create a device that will defy gravity. The company is examining an experiment by Yevgeny Podkletnov, who claims to have developed a device which can shield objects from the Earth's pull. Dr Podkletnov is viewed with suspicion by many conventional scientists. They have not been able to reproduce his results. The project is being run by the top-secret Phantom Works...

Date: Posted 7/12/2002 Fully Integrated Scramjet Missile Engine Tested At Mach 6.5 The Office of Naval Research (ONR) and the Defense Advanced Research Projects Agency (DARPA) successfully conducted the first-ever ground test of a full-scale, fully integrated hypersonic cruise missile engine using conventional liquid hydrocarbon fuel on May 30, 2002. The test, performed in a wind tunnel at NASA Langley Research Center, Hampton, Va., demonstrated robust operation of the engine at simulated hypersonic cruise conditions (Mach 6.5 at 90,000 feet altitude). Demonstration of efficient supersonic combustion ramjet (scramjet) performance with a liquid hydrocarbon fuel is an essential step to enabling...

MITEE - A Miniature Nuclear Propulsion Engine Chemical rockets have reached their limits. The hydrogen/oxygen chemical rocket can only deliver a specific impulse of about 450 seconds. The specific impulse is a measure of the thrust delivered by the rocket per unit mass of propellant consumed. Increasing the specific impulse to 1000 seconds, which is possible with Nuclear Thermal Propulsion, enables the spacecraft velocity to be over 2 times greater than that for a hydrogen/oxygen rocket, for the same mass of propellant consumed. Sidebar 1 compares the IMLEO (Initial Mass in Low Earth Orbit) for hydrogen/oxygen rockets with those for...

TOKYO (Reuters) - A man died after being sucked into the engine of an Air China aircraft at Kansai airport in western Japan Thursday and police said it may have been suicide. Police said colleagues saw Zhang Xinmin, a 39-year old Chinese member of the airline's maintenance staff, chase after the Boeing 767 as it began to taxi toward the runway for take-off. "It is possible he may have committed suicide, or he may have been running toward the engine for some other reason and was sucked in. We are investigating both possibilities," said a spokesman for the airport police....
