In Guns‚ Germs‚ and Steel‚ Jared Diamond opposed the idea that European civilizations have advanced further than their contemporaries in other continents because their inhabitants were intellectually superior. Instead‚ he supported the notion that some civilizations developed at a quicker pace than others because of the environmental differences that were present in the continents where they resided. Factors such as wildlife‚ climate‚ and the types of resources presented in an area have dramatically

pros and cons of weathering steel:: "Weathering" means that due to their chemical compositions‚ these steels exhibit increased resistance to atmospheric corrosion compared to unalloyed steels. This is because the steel forms a protective layer on its surface under the influence of the weather. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates

How A Steel Mill Works The principal consumables employed in steel production are iron ore‚ coal‚ scrap metal and electrical energy. The importance of each of these consumables depends upon the technological processes adopted at each mill. In a classic integrated mill‚ coal and iron ore are the main consumables. In semi-integrated mills‚ scrap iron is the mainstay. An integrated mill comprises four basic operations – reduction‚ refining‚ solidification‚ and rolling – to convert iron ore

Guns‚ Germs‚ and Steel Episode Three: Into the Tropics This episode was actually rather interesting. In general‚ it basically discussed how guns‚ germs‚ and steel have affected and influenced the shaping of African societies as it is today. Diamond’s main quest is to answer the question: why did the world become so unequal? In the mid-1600s the Europeans first arrive at the southernmost tip of South Africa. The southernmost tip of Africa and Europe are almost identical in latitude‚ with

This essay will focus on the benefits as well as the problems that staging the Games bring to that host country. The advantages are firstly about the enhancements of infrastructure‚ secondly are the potential of greater economic growth‚ and finally are the tremendous improvement in the national identity. On the other hand‚ the most serious problem faced by those countries is the
