Spam isn’t limited to the harmless email chain we’ve all been guilty of sending to friends and family members. Many of us feel that receiving email spam is a lost cause and we’re sentenced to cleaning our inboxes out each morning. Though completely ridding spam from your life may be an unattainable task, there are steps you can do for email protection :

• Create a separate email address (free ones like Gmail and Hotmail work great) when registering for an online group or Web-newsletter.

• When posting content on the Web, don’t include your primary email address. Spammers can easily add you to their lists.

• Trick the spam spiders-If you post an email address online, disguise it’s setup, spelling out ‘dot com’ in place of ‘.com

• If you sign up for a list, be sure it’s for that sole site and your information won’t get passed around.

• Read text-only emails or request your mail provider notify you before downloading images or HTML.

• If you receive forwarded chain emails from friends or family, ask them to stop. Even if you trust who is sending you the email, your name will still be visible to whoever continues sending the chain.

• Purchase a spam filter. It’s a small price to pay when you think of all the junk mail you’ll avoid.

www.perimetec.com notes several spam filters that can do the trick and reduce unwanted spam mail. The company provides web security services. Anti-spam filtering programs that can removes spam and prevents that user from ever forwarding you junk mail again.

LASER is an acronym for “Light Amplification by Stimulated Emission of Radiation.” In this definition radiation doesn’t refer to nuclear radiation, but to electromagnetic radiation. The electromagnetic spectrum includes radio waves, microwaves, infrared light, visible light, ultraviolet radiation, and X-rays. Some light wavelengths are visible, and other are not unless special equipment is used (e.g., infrared cameras, night-vision goggles). How is a beam of light able to delicately reshape the surface of the eye, yet still be able to cut steel in a laser cutting machines?Lasers operate by concentrating the strength of various forms of light. The strengthened beam is an almost perfectly straight beam, called a coherent beam. “Coherent” means that almost all of the light energy (photons) are traveling in the same direction. The laser light energy stays focused on a smaller area with greater power. A closer analogy to a laser is a magnifying glass. Remember as a child how you got the sun’s rays to focus on a tiny spot that got hot enough to burn? That’s similar to what a laser does, unless you moved the magnifying glass. Then the focus was lost and the sunlight was no longer concentrated. Because the laser employs a coherent beam, that essentially means it stays focused no matter the distance! Think of it link an infinite magnifying glass.

Lasers can perform a multitude of different tasks at different power levels. Specific light wavelengths and beam strengths can be achieved by altering the light source, power source, and even the color of the light. This extreme versatility allows both the shaping of a delicate cornea and the cutting of industrial steel. Laser has been proven to be beneficial for us, that’s why scientists keep doing researches on this technology.
