many variables involved. Ultrasonic plastic welding was first used in 1963. Robert Soloff experimented with a probe and used it to weld two halves of a tape dispenser together. Soloff then realized sound waves traveled around corners as well as down the sides of rigid plastics to weld the joint area. To automate the ultrasonic plastic welding machine he attached it to drill press using some simple mechanical items. This method of joining made the use of plastics wide-spread‚ and is still the most

My findings in the assumptions around bottle water and tap water resulted in a wide range of how the water supply is regulated. There are two different agencies that regulate the water supply in the United States. The Food and Drug Administration (FDA) regulates bottled water. The Environmental Protection Agency (EPA) regulates tap water. Both agencies are highly regulated agencies and have different standards of how the water is delivered to the consumer. The FDA manufacturing process is

Having observed these problems being encountered‚ this project will be developed to bring about the automation of the switching of lighting system using light depending resistor (LDR). The project is an electronic switch that is controlled (turned on and off) by the amount of light shining on the LDR. When light strikes the LDR‚ the switch opens (turns off); when the LDR is in darkness‚ the switch

Treatments for the plastic repair of a broken nose are first mentioned in the Edwin Smith Papyrus‚[6] a transcription of an Ancient Egyptian
