dimensions so the paintings looked more realistic. The new techniques consisted of use of lighting‚ shadows‚ and human anatomy. For example‚ Leonardo Da Vinci’s Mona Lisa included new techniques such as lighting and shadows and human anatomy. These changes occurred because art became less focused on religion and painted became more interested in the idea of humanism and man. The Renaissance intensely changed the people’s concept of religion. The printing press made the Bible more accessible to the

DISTRIBUTION OF HIGH AC VOLTAGES INTRODUCTION The potential benefits of electrical energy supplied to a number of consumers from a common generating system were recognized shortly after the development of the ‘dynamo’‚ commonly known as the generator. The first public power station was put into service in 1882 in London (Holborn). Soon a number of other public supplies for electricity followed in other developed countries. The early systems produced direct current at low-voltage‚ but their service

The American Revolution was the cause of a buildup of events. The rise of the revolution was brought on by a series of events‚ these are the main reasons as to why the American Revolution happened‚ the Intolerable Acts and the formation of the Stamp Act Congress. The Intolerable acts were a set of laws that colonists deemed unfair. These acts were put into place after the Boston Tea Party. The first act was the Boston Port Act the closed the port of Boston until the Dutch East India Company got

2.8 GHz Narrow-Band Colpitts Voltage Controlled Oscillator Design Literature Survey Report Bilkent University Electrical&Electronics Engineering Abstract Oscillators are one of the main building blocks of the electronic devices. They work on the principle of oscillation which is a periodic fluctuation between the maximum and minimum value of the quantity. Oscillators mainly consist of two parts: the active circuit and the resonator. In active circuit there are active circuit elements

Electrical cables are the major arteries for electrical power. The power utilities are facing new challenges due to liberalization of electricity. It means reliability demand on distribution network is increasing day by day. The distribution networks are mainly cable networks of different voltage grade and dielectrics. Therefore‚ the proof design of cables is required after installations. During installation the wear and tear of the cables are must due to mechanical and environmental stresses. Cables

the body‚ decapitations‚ stones or coins placed in the mouth of the deceased‚ and more (Gardeta & Kajkowski‚ 2013). Deviant burials occur for several reasons. For instance‚ one possible goal may be to extend punishment on the deceased as a result of a crime committed‚ or a personality flaw seen by society. It is even possible for deviant burials to happen as a result of human sacrifice. One popular reason for deviant burials‚ however‚ is to prevent the dead from leaving the grave (Guilliano‚ 2013)

Federation for Australia was when six independant Brisitsh colonies were no longer divided. It was the year “1901” when Federation happened for Australia. Federation took place because of the need to be more organised‚ to improve the defence of Australia‚ better transportation‚ stronger communication‚ to unify the economy and to strengthen the pride of being Australian. The idea of six colonies uniting as one had an apeal to people which lead to motivating the spirit of Australia and being as one
