Significant Historical Event that Occurred Between 1945 and 2008 Essay

Significant Historical Event that Occurred Between 1945 and 2008 - Essay Example That the event continues to be memorable is also indicated in the work of Persbacher (2005). According to Persbacher (2005), the events of 9/11 are even in the consciousness of the religious who made the event as a point for personal and theological reflections. Five years after 9/11, Persbacher (2005, p. 96) noted that religious groups reflected on the event and expressed that â€Å"religious faith affects reactions to horrific events† and that â€Å"horrific events affect religious faith† as well. Some of the more important events immediately after 9/11 had been recorded by the Migration Policy Institute. On 17 September 2001, the Immigration and Naturalization Service increased from 24 to 48 hours the length of time a non-citizen can be detained without charges (Migration Policy Institute, 2003). On 19 September 2011, Attorney General John Ascroft presented to President George Bush the administration’s proposed anti-terrorist measures (Migration Policy Institu te, 2003). At least 480 persons were arrested by the end of September 2011 for various charges related to the 9/11 bombings and the figure increased to 1,000 around October (Migration Policy Institute, 2003). On 1 October 2011, President George W. ... 2). On 31 October 2001, US Attorney General Asroft recommended to the US Secretary of State 46 groups for inclusion in the list of â€Å"terrorist organizations† under the provisions of the US Patriot Act (Migration Policy Institute, 2003, p. 3). Indeed, from these alone, it is easy to conclude that 9/11 directly and significantly affected American lives. Along the way, we also discuss how 9/11 affected the lives of all people in the world today. Versions and Interpretation of 9/11 Tamney’s (2004, p. 599) documentation of the 9/11 are as follows. On 21 September 2001, men inspired by Islamic convictions â€Å"hijacked four passenger planes flying over the United States.† Tamney (2004, p. 599) continued that â€Å"three of the four planes were crashed into the Pentagon in Washington D.C. and the twin towers of the World Trade Organization in New York City.† According to Tamney (2004, p. 599), â€Å"at least three thousand people died as a result of these a ttacks.† Tamney (2004, p. 599) pointed out that soon after, Journalist Oriana Fallaci published The Rage and the Pride in which â€Å"she argued that the terrorist attacks expressed the essence of Islam, that most Muslims were happy about the attack, and that Muslims are out to destroy the West.† According to Tamney (2003), Fallaci’s book became a bestseller in Italy and France and was soon published in the United States in 2002. Many believe that the terrorist attack on 11 September 2011 was successful because the attack has been a surprised. However, Dahl (2008, p. 19) consider this as a conventional wisdom that must challenged: more often investigations showed that the â€Å"warnings have been available but were either misunderstood or ignored.† According to

Lab experiment - microwave assignment - Essay Example The source of the signal that the system uses is termed as the Gunn Oscillator, which is at a signal of 10.5 GHz. the maximum output power that is recommended for the frequency ranges between 20 Mw to 10 Mw, and the recommended range may vary from time to time in different Gunn Oscillators. The output power may as well be varied by varying the voltage supplied that is received by the Gunn Oscillator via the unit cable attached to it (Campanella 2010). The devise consists of an adjuster, which helps to regulate the level of the power at the microwave point of input and in making of the measurements of the attenuator. This assignment makes use of the side-vane attenuator that uses the fiberglasses that are plastic in nature having resistive coatings in order to achieve the required attenuation. The fiberglasses are erected vertically with respect to the wave-guide and to the short walls in a parallel manner. The position of the blades on the wave-guide dictates the resulting attenuation of the whole system. Each attenuator is calibrated separately due to differences in the attenuation characteristics. Wave-guide support is a system component that acts as a stand and helps in the system stability. The system supports are in parts, one of the supports is the system base while the other is the plastic piece that is attached to the rod end. Wave-guides can be connected to the support by placing it gently onto the plastic piece of the system located on the rod top. The height of the system support is adjustable with the help of setscrews located on the base of the system. For the sake of this assignment, cross-guide couplers were used which consist of two- waveguides that are joined to one another at an angle of 90 degrees. Signals of the microwave that propagates from waveguide couples with microwave signals and finally dictates the coupled signal propagation. Two openings are recommended on the walls. These openings should be
