GREAT DISCOVERIES CHANGE LIVES Do you like watching television? I love it. I do not know what would I do if televisions did not exist. It is interesting‚ in several years‚ they have become a huge part of our lives‚ our indispensables. J.J. Thomson was inspired by some scientists and he provided us the opportunity of having televisions in our lives. Also other scientists improved his thoughts and experiments which leaded to the invention of the television afterwards. It is not that simple of course

Fire tube boiler designing Fire tube boilers operate by sending combustion/flue gas by using a combination of straight tubes flanked by trouble held in identical vessel. Often identified by the variety of passes used (say for example a 3-pass or 4-pass fire tube boiler)‚ this refers to the variety of times combustion gas flows the capacity of the pressure vessel mainly because it transfers heat on the water. A wet-back fire tube boiler utilizes a water cooled publish zone (end closure). A dry-back

LEE DEFOREST AND THE EARLY AUDIONS In 1906 Lee DeForest announced the development of the first three-element vacuum-tube detector in The Audion: A New Receiver for Wireless Telegraphy‚ from the Scientific American Supplement. The original Audion was capable of slightly amplifying received signals‚ but at this stage could not be used for more advanced applications‚ such as radio transmitters. The inefficient design of the original Audion meant it was initially of little value to radio‚ and

assistance‚ the need for endotracheal intubation may arise. The practice of endotracheal intubation has been shown to provide a safe and patent airway‚ which can be mechanically ventilated when necessary. The use of an endotracheal tube also protects the patient by preventing aspiration when used correctly‚ and provides an extra rout for medication administration. The use of endotracheal tubes is very common‚ and provides many advantages in patient care. Tracheal tubes are not without fault though

Nowadays‚ a Pitot tube would be of use as a speedometer on aeroplanes. It is also found useful in industries where velocity measurements are required‚ where an anemometer may not be the most efficient instrument to use. There are three types of pitot tubes: Pitot tubes‚ Static tubes‚ and Pitot-Static tubes. The simple pitot tube essentially consists of a tube bent at - usually - 90°‚ with an open end pointing directly towards the fluid flow. As the fluid flows in the tube‚ it becomes stagnant
