English scientist. On one occasion‚ about 1830‚ he was showing one of his early experiments to a distinguished company at the Royal Institution in London. He showed that when a magnet was brought suddenly near a coil of wire‚ a slight current of electricity was produced in the wire. Afterwards a lady said to him‚ "But‚ Professor Faraday‚ even if the effect you explained is obtained‚ what is the use of it?” "Madam"‚ replied Faraday‚ "will you tell me the use of a new-born child?" The new-born child

The 2009 reading of Heroism‚ Institutions‚ and Police Procedural‚ written by producer and director Alasdair McMillan‚ focuses on Police Procedural within The Wire‚ an HBO series created by David Simons. The reading consists of multiple points that are stretched across the chapter‚ employing the beliefs of Plato‚ Foucault‚ and Simons. One consistent argument McMillan explains thoroughly throughout the text is how the institutions sway a character’s motives. These institutions are also what create

INTRODUCTION A full wave rectifier is a device which is used to rectify all the alternating current components in an alternating supply and make it purely a direct current. The two alternating halves of an alternation current are rectified in a full wave rectifier which is an advantage over a half wave rectifier. Most of electronic devices cannot withstand very high voltage or alternating current due to its intense high power. The use of batteries in all devices is not practical as their replacement

The design and modeling of microscale electro-mechanical systems (MEMS) is a unique engineering discipline. At small length scales‚ the design of resonators‚ gyroscopes‚ accelerometers‚ and actuators must consider the effects of several physical phenomena. MEMS devices and sensors may even utilize multiphysics phenomena for its very function or for increased sensitivity. To this end‚ the MEMS Module provides user interfaces for electromagnetic-structure‚ thermal-structure‚ or fluid-structure interactions

In the short story by Robert Collins‚ “The Soul of Capitalism‚” Hap‚ a farmer‚ who also is a traditional art lover sells a piece of barbed wire to a young man‚ who later makes a piece of art out of it and sells it for $15000.
