Nuclear Medicine - Essay Example The patients to undergo nuclear medicine procedures do not require undergoing any special programs before the procedure, except, in cases involving gastro-intestinal system. In this situation, the patient is subjected to fasting four hours prior to the procedures (Murray, 2009). Positron Emission Tomography (PET) can examine body chemistry and is applied in medical tests as CT and MR scans. The test shows more information on the body organs like their current state of functioning and their structure. Hybrid scanning techniques employ X-ray computed tomography (CT) or magnetic resonance imaging (MRI). This technique sees the structure of an organ with 0.5 mm resolution but nuclear medicine uses 5.0 mm resolution to observe metabolism(Ramer, 2008) Indium white blood cell scans by the nuclear medicine helps determine the structure of the blood cells and how they are functioning.This scan aids in detection of cancer and any malfunction in the cells. Scientifically, nuclear fusion produces power as an energy resource. This occurs in a nuclear reactor where fusion in the nucleolus of radioactive material helps produce a lot of power transmitted and distributed for different uses. Energy produced from these materials is obtained by an action of splitting uranium into two by action of a neutron. This leads to radiations and heat evolved from atom and the reaction is fission(Murray, 2009). The process of nuclear fission involves the conversion of uranium into pellets and into rods. Lots of water is required to cool the uranium rods. When the rods emerge from the water, they produce lots of heat controlled by raising or lowering them from the water surface. To obtain more heat we raise them further way from the water. The heat produces steam that runs power-generating turbines(Morris, 2006) III. The method of power production is environmental friendly and does not contribute to global warming. The Nuclear fission

A bill of rights is essential to protect citizens from their Essay

A bill of rights is essential to protect citizens from their government. Discuss - Essay Example Recent developments in the Philippines have put this Southeast Asian country in the news and have garnered the attention of the international community once more. This involves the spate of killings of activists and journalists by unknown elements alleged to be connected with the military. (Amnesty International, 2005, p. 202) According to the non-government organization KARAPATAN (Alliance for the Advancement of Human Rights) (2006), there have been 607 documented killings from January 2001 to May 30, 2006. Amnesty International, the European Union and the Catholic Church have each spoken out against the government to condemn these acts of politically-motivated state-sponsored executions. This paper will examine whether or not a bill of rights, standing alone, is enough to protect the people from the excesses of government and it will use the current Philippine problem of extra-judicial killings as background. It will argue that the defense of sovereignty -- and, as a corollary to that, internal security -- is not enough to justify the use of state-sponsored repression. The phenomenon of state-sponsored oppression is by no means unique to the Philippines. It has in fact been extensively researched and discussed all over the world. Says Mitchell and McCormick (1988, p. 476) Governments organize police forces and armies to protect their citizens, build schools and hospitals to educate and care for them, and provide financial assistance for the old and unemployed. But governments also kill, torture and imprison their citizens. This dark side of government knows no geographic, economic, ideological or political boundary. Such killings and torture demonstrate grave violations of political rights and liberties. It has been opined that political rights and liberties are of paramount importance because of their impact on other rights, such as social and economic rights (Bollen, 1986, p. 567). The universal condemnation of
