The good news about the ozone layer is not always frequent. On International Ozone Day‚ the report came in that the ozone levels have decreased above Montreal and other residents of southern Canada. The ozone layer shields the earth from most of the harmful radiation and light coming from the sun. The ozone reflects

OZONE LAYER The Earth ’s ozone layer protects all life from the sun ’s harmful radiation‚ but human activities have damaged this shield. Less protection from ultraviolet light will‚ over time‚ lead to higher skin cancer and cataract rates and crop damage. The ozone layer is one layer of the stratosphere‚ the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. Ozone is only a trace gas in the atmosphere only about 3 molecules for every

Introduction Prior to OSI‚ networking was largely either government-sponsored or vendor-developed and proprietary standards such as SNA and DECnet. In the UK work on the Experimental Packet Switched system circa 1973‚ the need to define so called higher level protocols above the HDLC link level communications protocol and the content of an NCC publication ’Why Distributed Computing’ resulting from considerable research into future configurations for computer systems resulted in the UK presenting

Skin Layers 1. Epidermis The epidermis is the outer most layer of skin. It is built up of 5 layers (from the outside in) - stratum corneum is made of dead flat skin cells - stratum licidum - stratum granulosum - stratum spinosum - stratum basale Where cells divide and push previously formed cells into the upper layers. As the cells travel into the higher layers‚ they flatten and die‚ eventually. Specialized Epidermal Cells - melanocyte - produces pigment (melanin) - Langerhans’

and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth‚ the thinner the atmosphere gets. 1.TROPOSPHERE This is the layer of the atmosphere closest to the Earth’s surface‚ extending up to about 10-15 km above the Earth’s

The four step process to locate and load the Internetwork Operating System‚ or IOS‚ is known as the boot sequence. These are the steps that a router must follow in order to bring the device into an operational status. The first step is known as POST. POST is a ROM based program that runs whenever the device is booted up. This is where the hardware will get checked to ensure they are “operational

“BROOKLYN BRIDGE” The Brooklyn Bridge’s construction is one of the great achievements in United States history and helped pave the way for New York City’s rapid expansion in the 19th and 20th centuries. It was an undertaking that required extraordinary effort‚ sacrifice and ingenuity by its designers as well as its builders to complete. Its completion was a feat of engineering that was unmatched in its time: it was the longest suspension bridge – the first to use steel-wire – and dominated the New
