Another important factor is the distance between the worker and the source of radiation. In the case of arc welding, infrared radiation decreases rapidly as a function of distance, so that farther than three feet away from where welding takes place, it does not pose an ocular hazard anymore but, ultraviolet radiation still does. This is why ...
Reduced range of electromagnetic fields (EMF) emission, into the surrounding area. However, depending on the depth of the underground cable; greater EMF may be experienced on the surface. [ 4 ] The electric current in the cable conductor produces a magnetic field, but the closer grouping of underground power cables reduces the resultant ...
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
When a limb of a salamander or frog was amputated, the voltage at the cut (measured relative to the central part of the body) changed from about -10 mV to +20 mV or more the next day—a phenomenon called the current of injury. In a frog, the voltage would simply change to the normal negative level in four weeks or so, and no limb regeneration ...

These emissions are correlated to the video image being displayed, so, in theory, they can be used to recover the displayed image. While the phenomenon had been known by the United States Government and Bell Labs as early as the Second World War, the process received its name after Wim van Eck published the first unclassified technical analysis ...
Again, the source of energy for the electron-liberation is a high-energy photon from an atom within the plasma body relaxing after excitation from an earlier collision. The use of ionized neutral gas as a source of ionization is further diminished in a negative corona by the high-concentration of positive ions clustering around the curved ...
Movie Edit Pro (also known as Magix Video Deluxe in Europe) is a video editing software developed by Magix for semi-professional and DIY users for Windows PC. It is the best selling video software in Europe, and is most famous for its ease-of-learn and rendering stability. [1] The first version was published in 2001.
