Reduce harmful mobile radiation


1. When on a call, use a wired headset or speakerphone mode. Use a Bluetooth headset, which emits a smaller amount of radiation, only when talking. When not using the headset, keep it off your body.
2. Place the mobile phone away from your body when on a call.
3. Do not carry mobile phones in pockets of pants or in shirts. Use a belt holster designed to shield the body from radiation.
4. Avoid using a mobile phone in a moving car, train, bus, or in rural areas at some distance from a cell tower. Distance from a cell tower will increase the cellphone's radiation output.
5. Turn the mobile phone off when you don't need to use it.
6. Use a corded landline phone instead of a wireless phone, which also emits radiation.
7. Avoid using mobile phone inside of buildings, particularly those with steel structures, which increases the device's radiation output because signals are not as strong.
8. Do not allow children, whose bodies are more vulnerable to absorbing radiation, to sleep with a cellphone beneath their pillow or keep it at the bedside.
9. Do not allow children under 18 to use a mobile phone except in emergencies.
10. When making a call, do not hold the phone to your ear until after the person on the other line answers. The device emits more radiation before a call goes through.

Silver


Think of silver and what comes to your minds? Yes silver ornaments and silver ware and silver coins. But this is not all.
The other uses of silver are as follows:
Silver is used in the manufacture of crystalline solar photovoltaic panels. A mirror-like panel having a layer of silver that, when mounted on a building, acts like an air conditioner. Silver is used in water purifiers. The use of silver in photography, in the form of silver nitrate and silver halides Thermal or infrared telescopes use silver coated mirrors. Silver and silver alloys are used in the construction of high-quality musical wind instruments of many types.Flutes, in particular, are commonly constructed of silver alloy or silver plated. Silver stains are used in biology to increase the contrast and visibility of cells and organelles in microscopy. The medical uses of silver include its incorporation into wound dressings, and its use as an antibiotic coating in medical devices. filling for tooth in detistry. silver contacts in microelectronics. silver foil for sweet meats. silver coating.
...hope you enjoyed these shiny silvery reading moments...

Magnet


A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.
The uses of magnet are as follows:
Magnetic recording discs. Credit, debit, and automatic teller machine cards: All of these cards have a magnetic strip on one side. TV and computer screens containing a cathode ray tube employ an electromagnet to guide electrons to the screen. Speakers and microphones: Most speakers employ a permanent magnet and a current- carrying coil to convert electric energy (the signal) into mechanical energy (movement that creates the sound). A microphone has a magnet too. Electric guitars use magnetic pickups to transduce the vibration of guitar strings into electric current that can then be amplified. Electric motors and generators also have magnets. Hospitals use magnetic resonance imaging to spot problems in a patient's organs without invasive surgery. Chemists use nuclear magnetic resonance to characterize synthesized compounds. A compass (or mariner's compass) is a magnetized pointer free to align itself with a magnetic field, most commonly Earth's magnetic field. Vinyl magnetic art is not for the refrigerator anymore. Magnets have many uses in toys. M-tic uses magnetic rods connected to metal spheres for construction. Note the geodesic pyramidToys, magnets are often employed in children's toys, such as the Magnet Space Wheel and Levitron, to amusing effect.magnet in toy lift magnet in toy well Magnets can be used to make jewelry. Necklaces and bracelets can have a magnetic clasp, or may be constructed entirely from a linked series of magnets and ferrous beads. Magnets can pick up magnetic items (iron nails, staples, tacks, paper clips) Some screwdrivers are magnetized for this purpose. Magnets can be used in scrap and salvage operations to separate magnetic metals (iron, cobalt, and nickel) from non-magnetic metals. Magnetic levitation transport, or maglev, is a form of transportation that suspends, guides and propels vehicles (especially trains) through electromagnetic force. magnet to seal on the purse, magnet in pencil box cover, bits of magnetized papaer bits dance suspended in water in lamp shade, medicinal magnetic toe ring, magmet for magnetic massage, magnetic latch for the door, magnetic crane, magnetic films in giant magnetoresistance chip, magnetic gears to prevent slipping
