  NETWORK MARKETING - What Is Network Marketing? Network marketing is a business model that depends on person-to-person sales by independent representatives, often working from home. A network marketing business may require you to build a network of business partners or salespeople to assist with lead generation and closing sales. There are many reputable network marketing operations, but some have been denounced as pyramid schemes. The latter may focus less on sales to consumers than on recruitment of salespeople who may be required to pay upfront for expensive starter kits. What Does Network Marketing Mean? There are many well-known companies whose business model is based on network marketing. A few examples are Avon, Amway, Herbalife and 4Life. These companies have different tiers or levels that are created each time a new member is added to the network. Depending on the number of levels these systems have they can be classified as single tier, two tier and multi-level. ...

  TRANSISTOR & TYPES OF TRANSISTOR - A transistor is a semiconductor device used to amplify or switch electrical signals and power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more are found embedded in integrated circuits. Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually construct a working device at that time. The first working device to be built was a point-contact transistor invented in 1947 by American physicists John Bardeen and ...

  CLUTCH ANATOMY - The four parts that make up the clutch are - Clutch Plate. Clutch Cover. Clutch Bearing (Release bearing) Release Fork (clutch fork) WHAT IS A CLUTCH? ITS PARTS, FUNCTION, WORKING PRINCIPLE, REQUIREMENTS & MORE - What is Clutch? Clutch is a mechanical device used in the transmission system of a vehicle. It engages and disengages the transmission system from the engine. It is fixed between the engine and the transmission. The power produced inside the engine cylinder is ultimately aimed to turn the wheels so that the vehicle can move on the road. The reciprocating motion of the piston rotates a crankshaft by rotating the flywheel through the connecting rod. Clutch - The circular movement of the crankshaft is now to be transferred to the rear wheels. It is transmitted through the clutch, gearbox, universal points propeller shaft or driveshaft, differential, and axles extending to the wheels. With the help of all these parts, the use of engin...

  AVIATION FUELLING - An aviation fuel truck - At some airports, underground fuel pipes allow refuelling without the need for tank trucks. Trucks carry the necessary hoses and pumping equipment, but no fuel. Aviation fuels are petroleum-based fuels, or petroleum and synthetic fuel blends, used to power aircraft. They have more stringent requirements than fuels used for ground use, such as heating and road transport, and contain additives to enhance or maintain properties important to fuel performance or handling. They are kerosene-based (JP-8 and Jet A-1) for gas turbine-powered aircraft. Piston-engine aircraft use gasoline and those with diesel engines may use jet fuel (kerosene). By 2012 all aircraft operated by the U.S. Air Force had been certified to use a 50-50 blend of kerosene and synthetic fuel derived from coal or natural gas as a way of stabilizing the cost of fuel. Specific energy is an important criterion in selecting fuel for an aircraft. The much higher energy s...
