categories: obsolescence‚ surface degradation and accidents. Of these three‚ surface degradation of machine parts results in the machine’s loss of usefulness in the vast majority of cases. Surface degradation is comprised mainly of corrosion and mechanical wear. Corrosion of machine parts is quite common‚ especially for those with water-contamination issues. Water not only rusts iron surfaces‚ but it can also increase the oil’s oxidation rate‚ leading to an acidic environment within the component.

INNOVATION AND COMPETITIVE ADVANTAGE SUPPLY CHAIN SOLUTION: “GO CLEAN – GO GREEN” The supply chain process at Kuehne and Nagel has adopted the "Go Clean - Go Green" initiative which includes joining 14 ocean carriers and 12 shippers as member of the Clean Cargo Working Group (CCWG). The carrier members measure the actual consumption of bunker fuel and subsequently apply a common methodology for calculating and providing their individual trade-lane based carbon dioxide emissions per gram/TEU/km.

Abstract On 28 April 1988‚ Aloha Airlines Flight 243 experienced structural failure and consequent explosive decompression at 24‚000 ft. over the Pacific Ocean while en route from Hilo to Honolulu‚ HI. The flight crew enacted appropriate contingency procedures and was able to safely land the aircraft at Kahului Airport in Maui. During the event‚ an 18-ft. section of the fuselage skin had separated from the aircraft. The study of this accident and the safety issues identified as a result are classic

NANOTECHNOLOGY IN AVIATION Israel Stephen U. Manigandan D. III Yr‚ Aeronautical Excel College Of Engg. & Tech ABSTRACT: In the aerospace industry‚ there is a great need for new materials which exhibit improved mechanical properties. Materials possessing high strength at a reduced mass and size make lighter aircraft with lower fuel consumption. The development of new materials with tailored properties is a primary goal of today’s materials science and engineering. This paper gives us a brief idea

1.0 Introduction The minor equipment that is designed in this project is lean/rich MEA heat exchanger E-114. This heat exchanger is a counter flow shell and tube heat exchanger and is designed to heat up the rich MEA stream flowing from the CO2 absorber to the stripper. The principle that is applied is heat exchange between cold stream and hot stream which in this case the heat energy is transferred from the lean MEA stream to the rich MEA stream. Apart from this‚ the chemical engineering design

The Lawn Mower – Notes - Before the invention of the lawn mower‚ grass was maintained through animals grazing the area. - Birds such as chickens and geese were either able to roam freely or were kept in movable pens while sheep and cattle cleared the larger areas of grass. - A scythe was used to cut off plants that the animals wouldn’t eat - The lawn mower was invented in 1830 by an English Engineer named Edwin Beard Budding - Obtaining his idea from observing a machine in a local cloth mill

new process which replaces copper‚ the origin of corrosion in mirror‚ with a highly sophisticated multiple level chemical treatment. In this process‚ the silvered layer is applied on the glass by a chemical method also knows as the wet film method. To reinforce the adhesion of this layer‚ a preparatory surface treatment of the glass is done by sensitization followed by passivation. The silvered layer is then treated to endow it with anti-corrosion properties and to improve adhesion of the paints
