The Role of Surface Engineering in the Automotive Industry The subject of surface engineering in the automotive industry has developed significantly in the last decade. A large driving force for the need for surface treatments has been energy consumption. 30 per cent of all energy consumed in the European Union derives from transportation activities‚ relying solely on fossil fuels. Due to this‚ and the push to reduce the emissions of polluting gases‚ car manufacturers must produce increasingly

The Biogeochemical cycles of Earth Earth with its many species and abundant live is a Biosphere in flux. As time passes with the seasons‚ the earth turning upon it’s axis and the movement of the sun’s rays North to South‚ makes it a place of movement and cycles. There are four cycles that are considered the four major biogeochemical cycles. The hydrologic‚ this is the transport of water around the globe. The nitrogen cycle‚ this is the movement of nitrogen within the biosphere. The carbon

Beginning of Life on Earth Question 1 a) What is one of the suggestions for the beginning of life on Earth? What is the problem with this idea? The article states that suggestions have been made that germs of life may have made their way to Earth from outer space. This may have occurred due to comet dust resting on the Earth’s surface. Another theory proposed by Francis Crick states a spaceship sent out by a distant civilisation may have contained the first signs of life. The issue with these ideas

In the play The Crucible written by Arthur Miller‚ there are many interesting characters contributing significantly to the thematic concerns of the play. One of them is Elizabeth Procter‚ cold and unforgiving to her husband after he committed adultery. Despite her coldness‚ she is a very faithful woman with an honest personality‚ which is compromised by her deeply felt love for her husband. The presentation of such complex personality reflects the ideas of love and forgiveness in the play.

Odysseus is the hero that the Achaeans most admired. His intelligence‚ wit‚ and morals of the day allow the Greeks to look up to him as a role model. Perhaps the greatest characteristic that separates Odysseus from the suitors and his fellow shipmates is the wit and ability to trust the gods with their advice. The Odyssey begins 10 years after the Iliad had left off and Odysseus is trapped on an island with Calypso. Odysseus then has many hardships upon which he overcomes through his intelligence

Guests. I am going to tell you about “life beyond earth”. And ways that prove it exist‚ by finding evidence through the internet. Mars was once warmer many‚ many years ago. The planet was warmer and wetter than it is today. There was also evidence of dried river beds. Mars began billions of years ago when it was warm and wet. Today the surface is too cold and dry to support life. Scientists think that there might be ice under the surface. Life was once on Mars‚ but now there is no longer

In mathematics‚ the Klein bottle ([klaɪ̯n]) is a non-orientable surface‚ informally‚ a surface (a two-dimensional manifold) with no identifiable "inner" and "outer" sides. Other related non-orientable objects include the Möbius strip and the real projective plane. Whereas a Möbius strip is a two-dimensional surface with boundary‚ a Klein bottle has no boundary. (For comparison‚ a sphere is an orientable surface with no boundary.) The Klein bottle was first described in 1882 by the German mathematician

What you may or may not have known is that the Earth is actually flat. In this paper I will insert testimonies from several celebrities and scientists while giving reasoning behind this claim. Flat Earth Society has several facts behind this. One is the Bedford Level experiment shown here. The first investigation was carried out by Samuel Birley Rowbotham (1816-1884)‚ the president of the Flat Earth Society‚ in the summer of 1838. He waded into the river and used a telescope held eight inches above

The Last Town on Earth The Last Town on Earth in it of itself is an interesting read because unlike most historical fictions‚ the author does not drag the story with too many details‚ but captivates its reader with re occurring themes such as the irrational behaviors during a crisis‚ the American reluctance to enter World War I‚ the attitude towards war – which keeps the plot from fading away. Thomas Mullen brings the setting of his first novel in a mill town called Commonwealth in the

ALKALINE EARTH METALS what are alkaline earth metals? Alkaline earth metals are elements that are in the second group of the periodic table. the elements have two electrons on the outermost shell. the elements include Beryllium‚ magnesseum‚ calcium‚strontium‚ barium and Radium.The alkaline earth metals are all silvercolored and soft‚ and have relatively low densities‚ melting points‚ and boiling points. In chemical terms‚ all of the alkaline metals react with the halogens to form the alkaline earth metal halides
