Ethanol‚ a Fuel? Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch‚ the ground grain is then mixed with water‚ heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the

RAD (Rapid Application Development) refers to a development life-cycle designed to give much faster development and higher-quality results than those achieved with the traditional life-cycle "Rapid Application Development is a software development process developed initially by James Martin in the 1980s. The methodology involves iterative development‚ and the construction of prototypes. Traditionally the rapid application development approach involves compromises in usability‚ features‚ and/or execution

WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Fossil Fuels which include Petroleum and Natural Gas were formed million years ago from the remains of plants and animals‚ are responsible 40% and 20% respectively for the world ’s energy. They were first discovered about 700-900 years ago‚ however since the first modern petroleum industry began in 1859‚ the demand for fossil fuels has escalated beyond our control. It had taken 50-300 million years to form‚ and yet we have managed to burn roughly half of all global oil reserves in merely 125 years
