Kulkarni Types of Corrosion and Their Effects on Aircraft Structural Integrity Introduction Today the vast majority of aircraft are made out of various types of metal. All metals are susceptible to corrosion which is why from the moment that any metallic aircraft component is manufactured it is treated to prevent corrosion. Certain elements are often added to base metals by manufacturers in order to create corrosion resistant alloys and metallic components are normally coated with corrosion resistant chemicals

CORROSION OF CEMENT PASTE In general terms cement products have good durability‚ but their strength will decrease or even damage structures with the role of some erosive media (such as soft water‚ acid water)‚ known as the erosion of cement paste. The main reasons for corrosion are: Soft-water Corrosion (Dissolution Corrosion) Rain‚ snow‚ distilled water‚ industrial condensate water‚ and the river water and lake water with low bicarbonate content‚ all of them belong to soft water. When hardened

Introduction Gravity is a force that pulls all objects on Earth to its surface at a rate of 9.8m/sec. Gravity is an acceleration of a free falling object (Encyclopedia Britannica‚ 2014). Gravitational potential energy (Egp) is a concept from the law of gravity. As an object is positioned with a gravitational field‚ the object can store energy which is called gravitational potential energy (Physicsclassroom.com‚ 2014). As the object begins movement or work the energy transfers into kinetic energy

Director Naval Architecture Naval Headquarters‚ New Delhi 1.0 Introduction : Steel‚ the most corrodible of all ship construction material‚ still remains the most economic choice of ship construction materials however‚ the very nature of steel‚ compounded by the salt laden marine ambience‚ makes the corrosion protection effort arduous. The marine environment is one of the harshest environments any structure could be subjected to. It is

Germination in plants is the process in which dormant seed begins to grow and sprout under certain growing conditions. The English pea‚ also known as the garden pea‚ is a member of the legume family and is known to grow roughly three to four inches long. Research shows that it only takes approximately 1 week for the seed to start to germinate. There are many things that can affect‚ the growth of the pea seed such as; temperature‚ moisture‚ planting depth and sunlight. The pea grows best in temperatures

Biology EEI Overview By Jack Chappell Introduction: The most common fungi in the world is Bread Mold Fungus‚ also known as Rhizopus stolonifer (NCBI database). This mold is a common problem in most households throughout the world. The experiment being undertaken‚ changes the ingredients in bread to test the rate in which mold grows differently. These results will also be accommodated with climate control and the effects that could be associated with temperature and humidity. Mold will
