It is tri atomic oxygen (03) and is a gas found in the troposphere as well as in the stratosphere. Tropospheric ozone is undesirable since it is a pollutant these‚ causing photochemical smog and greenhouse effect. In the stratosphere‚ it acts as a protectant since‚ (i) It absorbs the dangerous UV-radiations (ii) It helps to trap the weather pattern within the troposphere‚ by generating a temperative inversion in the stratosphere. Tropospheric ozone is increasing due to human activities‚ while

The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger‚ additional ultraviolet rays are allowed to pass through. These rays cause cancer‚ cataracts‚ and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970‚ Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started

The OSI model has seven layers‚ with each having different types of security responsibilities. The seven layers are application‚ presentation‚ session‚ transport‚ network‚ datalink and physical with control being passed down from layer to layer starting with application. The biggest threat to these layers is through people‚ sometimes known as the 8th layer of the OSI model. Companies should take the time to educate their employees on the security threats that each individual brings to the company

Article Reflection: Ozone Layer Ozone: The Pollution Paradox This article was based on information about ozone pollution. In my opinion this article gave a lot of valuable information and I learned a lot of things I never had knowledge of. For example‚ the atmosphere forms and destroys the ozone‚ the ozone can have an effect on the human body and the article also provided information on what we could do about the ozone layer to help the atmosphere. I had a little bit of information in my

The ozone layer is a layer in Earth’s atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 97–99% of the Sun’s high frequency ultraviolet light‚ which is potentially damaging to the life forms on Earth.[1] It is mainly located in the lower portion of the stratosphere The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist

Christine Snyder The atmospheric issue that I chose to write about is the Ozone layer depletion and the indoor air pollutant is Volatile Organic Compounds. I am going to talk about the cause and effect of each of these issues and also efforts to mitigate the issues. Our Earth’s Ozone layer protects all life from the sun’s harmful radiation. Due to all human activities damage has been done to our Ozone layer thus‚ causing harmful ray’s to enter and expose people to higher levels of Ultra Violet

The cell radio communication and wireless computer networks of GSM (Global System Mobile)‚ CDMA (Code Division Multiple Access) type are worldwide communication systems. All these communication systems are based on the reference model OSI-RM (Open System Interconnection-Reference Model) Description of OSI-RM System: OSI-RM is an International Standard ISO that defines

Some practice is needed to get a continuous body motion pulling the applicator across the plates to get an even layer. The glass plates must be the same thickness and extremely clean. Any oil or grease will result in a poor layer. Handle the plates with rubber gloves when washing or rinsing. Care is also needed if the edges
