In sulphur hexa fluoride ckt breaker, SF6 gas is used as the arc quenching medium. The SF6 is an electronegative gas and has a strong tendency to absorb free electron. The contacts of the breaker are opened. In a high pressure flow of SF6 gas an arc is struck between them. The conducting free electrons in the arc are rapidly captured by a gas to from relatively immobile ion. This loss of conducting electrons in the arc is quickly builds up enough insulation strength to extinguish the arc. The SF6 ckt breakers have been fou ....etc

The Controller Area Network (CAN) is an international standard defined in the ISO 11898. CAN was developed as a solution for networking in distributed real time systems. CAN which is a two-wire, half duplex, high-speed network system is well suited for high speed applications using short messages. It supplies high level security and high data exchange rates. One of the most important features of CAN technology is the guaranteed maximal latency for bus access that makes it the choice for real time systems. The scope of this seminar is to describ ....etc

Abstract

Sulfur concrete is a composite construction material, composed mainly of sulfur and aggregate (generally a coarse aggregate made of gravel or crushed rocks and a fine aggregate such as sand). Cement and water, important compounds in normal concrete, are not part of sulfur concrete. The concrete is heated above the melting point of sulfur ca. 140 C. After cooling the concrete reaches a high strength, not needing a prolonged curing like normal concrete. Sulfur concrete is resistant to some ....etc

INTRODUCTION
Transportation contributes all round development of a country and hence plays a vital rate towards its progress. If the highways are not properly located and may contribute sediments to streams. The control of soil and water is basic to the protection of the road structure and therefore highway design, construction and maintenance must be continually evaluated to minimize erosion and sedimentation problems
