A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated.[4]When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. An LED is often small in area (less

CATALYTIC CONVERTER THEORY, OPERATION AND TESTING 2 The gasoline used in the modern automobile is a complex blend of both straight and branched chain hydrocarbons. In simpler terms it is a mixture of different types of bunches of hydrogen and carbon. We will use the fictitious molecule C8H17 to approximate the blend of different hydrocarbon compounds found in gasoline. In more simple terms one gasoline molecule* contains 8 atoms of carbon for every 17 atoms of hydrogen and nothing else*. ONE GASOLINE

place of establishment as they can be transported, provided the means of transport is cheap, efficient and reliable. Raw materials are divided into two categories namely: natural raw materials (for example, platinum used in making car catalytic converters) and raw materials that occur naturally but are cultivated (for example, wood). Labour availability For a business to function effectively, one of the contributing factors is the quality of labour. There should be enough skilled and unskilled

12 Assignment 1 Great Lakes Professor Mary May Bus 499 When analyzing the article “Great Lakes, Great Decisions” the six factors that are used are technological, demographical, socio-cultural, economic, political, and global. The technologically that is available is starting to leave the company behind. The article stated that some countries had not yet switched from leaded to unleaded gasoline for their cars and machinery. When the new technology is used this could leave behind some

The heat was unbearable as I pulled up to the starting line. The smell of exhaust gases and burned rubber filled the air. The starting light received my fullest attention, zoning everything out of my conscience. 3...2...1...green light! I stomped my foot on the accelerator as I side stepped my clutch. Shifting into second gear, I flipped the switch to my nitrous oxide system. Instantaneously I was thrown back into my seat. All of a sudden a loud pop disturbed the smooth
