Executive Summary Optical fibres are being increasingly used in the telecommunications industry. They are slowly replacing the conventional copper cables due their superior ‘data transmission’ properties. They transmit data via light pulses within glass or plastic strands. Fibre optics fit the material requirements for good data transmission since they are ability to transmit and preserve quality of signals‚ durable and cost-effective. Some of the current materials employed within the industry are

Testing Piaget Theory In The Preoperational Stage Of Devolpment A friend’s uncle‚ who lives in the area‚ has a set of fraternal male twins named Justin and Christian that just a week ago‚ turned four years old. And after getting a good connection through my friend‚ I was invited over to do a few of Piaget’s experiments on each of the boys. Being twins‚ both boys obviously fit into the preschool age-range and I determined that I should test their preoperational thought as it relates to their conservation

In my 100i class I recently read an article called “O.K.

the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic feet per hour (SCFH)‚ the small glass beads could enter the flow meters. This would result in damages to the flow meters and in flow meters giving false readings which in return could result in the team‚ conducting the experiment‚ to adjust flow

In 1903 a French chemist Edouard Benedictus accidentally dropped one of his flasks on the ground even though the glass broke it did not shatter. He later found out it did not shatter due to the element that was held in it which was liquid nitrate solution. In 1909 Benedictus successfully filled a patent in France for his glass. In 1914 Benedictus moved to The

The film itself seems to have been made on a dark and gloomy day‚ with few bright colors. This gives off a feeling of somberness. These cold spaces and hard surfaces might suggest Hoffman’s loneliness. The fish is alone in the glass tank‚ just like Hoffman is alone in the glass building. Hoffman seems to be very focused
