Mobile Phone Dangers

mobile-phone-dangersWherever you may go, you always find a person talking over a mobile phone. Even at a place where the cell phone is prohibited you can find a few people talking over their phones or at least using the SMS facility of their mobile phones.

An Explosion In Cell Phone Use

Mobile phones have become a craze the world over and especially in the last decade their use has increased tremendously. More than one billion users use the cell phones all over the world. As a result, at any given time there are a lot of phones that send their waves of different frequencies in the in the air. So, people have become increasingly concerned about the danger from these cell phones. According to a study, the cases of brain cancer have increased in the last decade, after the introduction of these phones. All the more, brain tumors have been found to occur at the same spot where persons keep their phone while talking. It is implied from such studies that long-term mobile phone use may be a cause of brain tumors and brain cancer.

Why Are Cell Phones Dangerous ?

Actually, when we use cell phones, they emit radiation. The level of this radiation is though quite low. However, if we use the hands-free gadget, exposure to this radiation is increased. Some experts point out that apart from the health related danger of cell phones, the danger of inattentiveness is more prominent. When people are using cell phones, they become oblivious of their surroundings and are at an increased risk of meeting with an accident. Driving becomes careless and your life as well as the life of other people is in grave danger. If you use a hands free set, you can use both the hands properly, but you attention is still with your mobile phone. The risk of an accident is still very high.

Is There Any Ray Of Hope ?

Everything is not that gloomy and pessimistic. A study in Denmark that involved more than half million cell users indicates that there is no solid proof that brain cancer is related to cell phone use. However, studies do indicate that the persons who use analogue phones are at risk of brain diseases. So much variance in studies has led to a divergence in opinion regarding health risk from mobile phones. More studies need to be done before arriving at a particular conclusion. Also, now cell phone companies are devising ways so that the exposure to radiation while using phones can be reduced to a minimum. Gradually, this exposure will be totally eliminated by the rapid advancement in technology. So, until then, you should avoid talking over mobile phones for hours at a stretch and should not use them while driving or while walking on roads. You should not think about throwing your mobile phones away as they are of great use in the modern day world.

Screensavers Make You Relaxed

Therefore it is utmost necessary that you should check the configuration of your computer before attempting to download a screensaver, If the specifications of your computer are at par with those mentioned in the web page from where you want to download your screensaver, go for it without any fear.

You can also create your own costumed screensavers using some related software applications. You can fill in those videos and audio that are extremely liked by you.

What is Fiber Optic Technology ?

fiber-opticArt as well as Science is required as to know how the fiber optics are made and how they function for different uses in our day today lives. Fiber optic materials are made of those materials that transmit light. Bundles of very slim fibers of plastic or glass are packed into a tube. One end of such a fiber optic is placed at the light source and the other end functions as the lens of a camera.

Light is channeled through these fibers. Not only light but everything associated with light, images for example, also get transmitted from one end of the fiber optic to the other end. Bends and turns in the fibers pose no hindrance in this transmission.

The core of fiber optic materials is made of glass or plastic and it is highly transparent. This core is covered with a covering known as ‘cladding’. When light enters from one end and travels through the length of the fiber optic, this ‘cladding’ does not allow it to scatter outside the material.

The ‘cladding’ reflects all the light from inside the surface of the fiber optic. So, even if a bundle inside the fiber optic is not straight, the image is not affected. Fiber optics are capable of carrying light and other information over a wide range of distance. The distance may vary from a few centimeters to many hundred kilometers.

Fiber optics are primarily of two types. The single-mode fiber optic and the Multi-mode fiber optics.

Single Mode Fiber Optic

It is suitable for transmissions over long distance that happen at tremendous speed. They are capable of this because their core is very small and they have the property of accepting light only in the direction of the axis of the fibers. Small lasers are used to send light into fibers. The fibers are joined with low-loss connectors so that there is very less distortion of the light signal.

Multi Mode Fiber Optic

In multi-mode fiber optic materials the cores are big and they also can accept light from a variety of angles and can also function with a variety of light sources. The connectors that are used within the material are not very expensive. It is done because these fiber optic materials are not meant for long distance transmission.

Usage of Optical Fiber Technology

There are myriad uses of fiber optic materials in the technology savvy world of today. Communication systems use fiber optic materials in abundance and hence are highly superior to those communication systems that use the traditional copper cables. These systems do not need a lot of amplifiers, witness very less electrical interference and have a huge information- bearing capacity.

The messages are transmitted in numeric codes with the help of lasers. The lasers are flashed on and off at extremely high speed. This numeric code can comprise of different types of files like audio, text, numbers, illustrations etc. Fiber optic materials are also used in industries for many types of applications.
