At this moment in almost every aspect of the job is always to use the computer as the main facility. Computers function is to calculate at this time identified more by typing the type of activity. But outside of that, the teenagers who knew the computer was more likely to utilize Internet as a means of friendship. Communicate and make friends in one of the blogs of friends like my space or face book for example.
That any activities associated with the computer, much less make them survive longer sit facing the computer device. Many minutes even hours without realizing just missed time.
Computer use can cause constant complaints on several members of the body. For example in the neck muscles feel stiff and sore. Eyes that seemed vague, and so forth. We unknowingly, computers can actually cause disease because of its use. Starting from the layout of tables and chairs, monitors, keyboards and printers are devices that can cause disease in their use.
To reduce complaints during working with computer, it’s worth a place used in computing should be designed in such a manner. Sitting in the typing position should also be considered. Recommended, we must sit in an upright position and relaxed and the position of one of the legs slightly forward. (more…)

How to maintain eye health from computer radiation

Monday, February 22nd, 2010
The easiest and most commonly used to produce microwave radiation, is one who is to pass through the high frequency currents. It was the method used by Hertz in his famous experiments and the method is still used today in all transmitters.
In the minds of many technicians, radiation and high frequency power became synonymous. However, this view is not permissible and the thing seems obvious to some one wants to think it over.
The current high frequency radiation is no longer a current phone is a sound vibration. To move from one state to another, you must use a power transformer which is in the first case, a radiator or wave transmitting antenna, and in the second case, a loudspeaker.
An electrical circuit may be the site of a current high-frequency intense without any trace of radiation. It is therefore interesting to try to understand how we can move from a current high-frequency energy radiated.
Infrared and ultraviolet radiation
Saturday, December 26th, 2009
Infrared Radiation or Thermal: These rays are visible but its wavelength falls between 8,000 Angstroms and 0.3 mm. A body subjected to heat (over 500 ° C) emits heat radiation, which can be made visible when the body temperature is high enough. We must point out that these rays are not the only producers of caloric effects. We know that the hot bodies emit infrared up, but all radiation can be transformed into heat when absorbed. (more…)
