Temporary storage

Posted on September 18, 2010 at 3:32 am

A computer memory is also know as RAM or Random Access Memory and it stores everything you are currently working on and recently worked on. Whether you have IBM Memory Upgrades, Toshiba Laptop Memory or even Sun Server Memory, all of these are memory that is very essential part of your personal computer because it stores vital information that you are using and need access too immediately. Computer memory manages no matter what the data is, picture, sounds or even text, if you get a good amount of memory, your computer will load that data much faster and store it better.

The bigger the amount of your memory, the faster your computer works and performs task. Basically, computer memory is a temporary storage for instructions in order for it to run. These sets of instructions are the ones responsible on how long will it take for a particular application to run and operate. The memory you install to your computer will dictate how fast your operating system will load as well as the application installed into your computer such as your office, games, antivirus and many more that are essential as well to your computer. You computer memory will make wise of working even faster with your computer.

Meltdown

Posted on July 3, 2010 at 8:16 am

Mush of Alaska is covered with permafrost, a layer of permanently frozen soil that lies just below the surface. Warmer temperatures are now causing the permafrost to melt in some places. As it melts, the ground softens and water wells up to the surface. Trees growing in the top soil layer tip sideways and their roots drown. Melting permafrost is creating big problems for Alaskans. Where houses were build one once-solid frozen ground, foundations are shifting and cracking. Roads are buckling and sinking. Even the Trans-Alaska Pipeline, which carries petroleum 800 miles from Alaska’s North Slope fields to the port for shipping.

Melting permafrost is also increasing the risk of erosion and landslides. Alaska’s more than 2,000 glaciers are causing worries, too. Scientists have expected the glaciers to get thinner as a result of warmer temperatures. But in 2002 studies showed than many Alaska’s glaciers are shrinking even faster that scientists had thought.

Aerometer

Posted on February 22, 2010 at 8:00 am

The aerometer also called hydrometer is an instrument for measuring the density and weight for a fluid whether gas or liquid. Its body is made of hollow tube with a widened bottom to which a weight is attached. This weight, usually lead or mercury, keeps the instrument upright when it is placed in the substances to be measured. The hollow tube narrows upward into a graduated road or stem.

The density of the liquid is determined by reading where the scale penetrates the surface of the liquid. This instrument is based on the principle of Archimedes, which states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid, this is also known as the principle of buoyancy. Since the weight of aerometer is fixed, it is possible to measure the density and weight of a fluid based on how deep the device sinks in the elements.

Where has the night gone?

Posted on January 19, 2010 at 7:59 am

You know about air pollution and water pollution. And you’ve probably heard of noise pollution. But have you even seen light pollution? If you’ve ever stepped out on a clear night to see the stars and found the sky filled with soft glow, you have. That glow isn’t the aurora borealis, which paints the sky in Arctic regions. It’s light pollution. In most of the world, it’s getting harder and harder to see the stars at night –because so many electric lights are burning around the clock.

Powerful outdoor lights are blocking out the stars, wasting electricity and having harmful effects on wildlife. But many communities are taking action to end light pollution. All kinds of outdoor lights, airport lights, security lights, shopping-mall lights, billboards lights and even the flood lights and other outdoor lights around homes –are responsible for light pollution. Many of these lights shine out and up, not just down.
