ASSIGNMENT: 1 SESSION: 2012/13 TUTOR: Stuart Allan WORD COUNT: 1‚891 Carbon fibre is a strong‚ yet light‚ reinforced polymer. Carbon fibres are used in applications where high strength and light weight are required. Carbon fibres can also be easily moulded into the desired shape. They are also chemically inert‚ resistant to heat‚ and do not expand under changing temperatures. Machining of carbon fibre materials can generate airborne particles. The potential health effects of

Crystal Lewis 9/21/10 Period 1 Carbon Dioxide Carbon Dioxide is the infrastructure of all life on earth. Every human being and animal needs it to survive‚ making it an essential compound. In order to survive‚ humans and animals must give off carbon dioxide to take in oxygen‚ whereas plants must take in the compound and give off oxygen. Carbon Dioxide has numerous unique characteristics‚ properties‚ and safety measures that everyone should be aware of. Being aware of this compound and what it

international steel companies. The number of rivals in America is declining due to higher labor costs than in foreign countries. There is a very fast pace of technology in the steel industry and it seems that the company‚ that obtains the newest technology‚ flourishes. This is due to the difficulty in lower costs of steel production. Better technology is one of the only ways to decrease costs because labor is pretty much at a set cost and all that is left is the cost of iron and making the steel. If a company

Carbon-14 Dating: An Invaluable Yardstick in the Chronology of Humans Archaeologists utilize several methods to analyze data from the past. One scientific tool helps to analyze the radioactive decay of chemical elements found in plant and animal remains‚ pottery‚ and even rocks. Radiocarbon dating‚ also known as carbon-14 dating‚ has developed into one of the most important radioisotope dating methods archaeologists employ. This scientific tool‚ first developed by Willard F. Libby in the late

INTRODUCTION Since carbon dioxide concentration in the atmosphere is accumulating rapidly because of burning fossil fuel‚ coal‚ oil and natural gas for power generation‚ transportation‚ industrial and domestic uses‚ our earth has been facing global warming‚ sea level rising‚ flooding and other adverse changes which damage to our ecosystem. To address this challenge‚ we need to find out other alternative ways that do not produce carbon dioxide or that reduce the release of enormous amount of carbon dioxide gases
