Televisions previous to the Plasma TV explosion used the (CRT) cathode ray tube to give users the ability to watch television. CRT televisions works by shooting out a beam of negative charged particles called electrons into a large glass tube. These negative electrons
For the past 75 years, the vast majority of televisions have been built around the same technology, the cathode ray tube (CRT). In a CRT television, a gun fires a beam of electrons (negatively-charged particles) inside a large glass tube. The electrons illuminate phosphor atoms inside the tube (screen), this allows the TV picture to be produced by illuminating different areas of the phosphor coating, this is what gives you the CRT television.
Now welcome to the new face of television, Plasma TV. Plasma has taken the home theater market by storm because of their amazing picture quality and very thin design. The idea of plasma display panels began in 1964 at the University of Illinois. The first displays were very primitive using only points of light created in the laboratory. As time went on digital processing, and other technology, made vivid plasma displays a reality.
Plasma televisions use a much different type of technology thatn CRT models, they use something called pixels. Using a video signal the pixels on the flat screen light up with a high-energy beam of electrons that are separated into the 3 primary colors, red, green and blue. From the illuminated fluorescent lights pixels you get the full color spectrum that produces a full range of colors that give you the image on the screen. Each pixel on the screen has three fluorescent lights in it, a green, red and a blue fluorescent light. Each fluorescent light in the pixel can produce 16 million colors, giving you amazing colors and overall picture quality that you can't finder in regular CRT televisions.
Another feature that you can't find in CRT TVs is the widescreen design found on Plasma televisions. The (16:9) aspect ratio is the same dimensions used in movie theaters. This feature gives Plasma flat screen high definition television models a cinematic feel, that is great for watching feature films, concerts, Monday Night Football or anything else you can imagine.
And unlike conventional television models, there are no scan lines on plasma televisions, so the picture is much sharper. The viewing angle is far superior than CRT, there is 170 degree viewing angle so you can basically watch the TV from any area in the room. As I mentioned before Plasma Tvs are very thin, only 3.3 inches in width. This makes them perfect for hanging on your wall, freeing up space in your home. Just like a picture frame, you can now hang your television on your wall!
So who manufacturers these thin TV displays? You can choose from numerous brand names which I'm sure you are familiar with such as, Sony, Sharp, Hitachi and Samsung to name a few. Plasma isn't the only technology available if you are a HDTV buff, you should also check out LCD televisions and rear projection TVs.
And if you want to find a cheap plasma TV, check out the discount deals available through internet, particularly Amazon.com and Ebay.com. Those 2 online merchants are trusted and can offer not only new, but used and refurbished models for even bigger savings.

Plasma TVs At High Altitudes
Plasma TVs At High Altitudes
by: Jakob Culver
An interesting factor to consider when planning your purchase of a new plasma television is altitude. Plasma TVs use millions of tiny, gas-filled chambers to create a picture. When you move to higher altitudes, the constant pressure in the chambers and the now lower ambient air pressure create a buzzing sound reminiscent of a halogen beer sign. This buzz is a combined result of the increased power consumption necessary to overcome the pressure differential, and the increase in fan use because the high power consumption heats the unit. This change in noise is really the only difference between operating a plasma television at sea level and one operating at extreme (above 6,000 ft) altitudes.
This noise increase provides a hint as to the more serious reason to avoid using a plasma television: lifespan. The life of a plasma screen is dependent on how hard it works through the course of its life. Operating...

Cholesterol ? What Is It and Are You At Risk?
Cholesterol ? What Is It and Are You At Risk?
by: Paul MacIver
Cholesterol is a fatty lipid, steroid and an alcohol found in the body tissues and blood plasma of vertebrates. It is the essential part of the outer membranes of human body cells, and it circulates in the blood.
Cholesterol in the human body comes from two major sources. About three-quarters of the body?s total cholesterol is produced within the body, while only one-quarter comes from cholesterol in food.
Higher concentrations of cholesterol are present in body tissues which have more densely packed membranes ? i.e. the liver, spinal cord, brain, atheroma, adrenal glands and reproductive organs.
The liver is the most important site of cholesterol biosynthesis. It is secreted from the liver in the form of an acidic secretion known as ?bile?.
Diets rich in animal fats, meat, poultry, fish, oils, egg yolks and dairy products are a rich source of dietary cholesterol.
