In the horizontal plane of the fly, the first harmonic shows a dipolelike amplitude distribution whereas the second harmonic shows a monopolelike radiation pattern. The first frequency component is dominant in front of the fly while the second harmonic is dominant at the sides. Sound with a ...
Radiation generated by the passage of a monoenergetic electron bunch above the surface wave excited in plane interface between homogeneous media with different dielectric constants is investigated. For the surface wave of general profile the radiation intensity is expressed via the radiated power from a...

which gives us extra radiation exposure. With all of this—on top of the radiation exposure we get from sources other than flying, such as X-rays, CT scans, MRIs, devices such as cell phones, and even food and water—if we can take a step to protect our health, well-being, and vit...
Expert in radio frequency radiation, electromagnetic fields, dirty electricity and ground current."The U.S. spends over $2 trillion dollars on health care each year, of which about 78% is from people with chronic illnesses, without adequately exploring and understanding what factors, including EMF...
14. Of, relating to, or being the gear configuration or setting, as in an automotive transmission, that produces the greatest vehicular speed with respect to engine speed. adv. higher, highest 1. At, in, or to a lofty position, level, or degree: saw a plane high in the sky; prices...
s magnetic field and so particle flux comes from a quasi-2D plane perpendicular to the magnetic field. Here we conclude that the dose reduction originated from the rotation of bulkier parts of Orion into the proton plane (Fig.3d). This shows that preferential spacecraft orientations, in which...
Every time I pass through an airport — which is pretty often — I worry about the radiation I'm exposed to at airport security and then on the plane. But in a recent look at the evidence about the health effects of frequent flying, I learned that there's probably no need to fret.....
Because they are flying at relativistic speeds, they don't spend much time at any one location, the forces are mere nudges on their trajectories. It takes a persistent nudging to change their flight path, and this is most effectively accomplished through their interaction with electric and ...
