Electromagnetic - Assignment Example All the objectives would be achieved by carrying out several activities such as tests for magnetic shielding, falling magnets and the design of the motor. The lab activity was also aimed at using PHET simulation software to carry out some electromagnetic tests. Magnetic shielding is the act of reducing the electromagnetic field contained in space by blocking the area with barriers made of either conductive or magnetic material. Magnetic shielding, however, does not prevent a magnetic field, preventing lines of flux from traveling from the North Pole to the South Pole of a magnet. However, the fields can be redirected. Any ferromagnetic metal can be used as a shielding metal. A ferromagnetic metal is a material containing either nickel-iron or cobalt. Most of the steel materials are ferromagnetic metals and work well as redirecting shield. Steel is, however, most used because it is less expensive and widely available. The thickness of the shielding material matters to individual levels. When a shield is so thin, it becomes saturated with magnetic field lines and cannot hold any more lines of flux. Thick shielding is therefore required to carry a maximum number of flux lines. A thick shield does not necessarily mean adding more of steel mate rial. Adding steel thickness does not improve the shielding much. In such cases where saturation is an issue, multiple layers of the shielding material are used. There are some specialized materials especially designed for magnetic shielding. The Specialized magnetic shielding materials are always designed to have a higher relative permeability and a lower saturation point. The right shielding materials depend on the particular shielding problem. For instance for a sensitive electronic, Metals can provide an excellent shielding than steel. Or large applications involving large, powerful neodymium magnets,

Gay Marriage Essay -- Homosexuality, argumentative, persuasive

Marriage is the legal or religious ceremony that formalizes the decision of two people to live as a married couple. Marriage should not be based on what others think. When people get married in a heterosexual union, they do it for their own happiness, not for the happiness of others. Gay marriage is the same way. Homosexuality has always been around and will continue to exist. Why should homosexuals be denied the rights of heterosexuals? No one has the right to say that homosexuals can not marry. That is discriminating against another group of individuals who want equality. Gay marriage should be accepted; people were made with the capacity to love, no one should try to change that, not the Bible, the Constitution, or anyone. Marriage is stated many times in the Bible. But the Bible and the Amendments can be interpreted many ways. Marriage is a religious ceremony, â€Å"But I cannot imagine even the most fervent Christian obeying all of God’s laws†¦Ã¢â‚¬  (Bond) Nobody is perfect, but our flaws make who we are. If we don’t always follow a few rules here and there it is okay because we are only human. Most parents teach their children to be different and don’t let others influence them. The same thing should go for gays. The people that are trying to change them are not going to succeed. Gays were made fore a certain reason, but our country has to figure that out first in order accept them. In the Bible, Jesus blesses the children and sends the young rich men away†¦ Jesus said, ‘Truly I tell you, there is no one who left house, brothers, sisters, mother, father, children, or fields for my sake and for the sake of the good news, who will not receive a hundredfold now i n this age --- houses brothers, sisters, mothers, children and fields with... ..., it will come.

Models of American Ethnicities Essay

How does Fredrickson distinguish between race and ethnicity? How and under what circumstances can ethnicity become racialized’ (para.2)? Fredrickson says that â€Å"It can be misleading to make a sharp distinction between race and ethnicity when considering intergroup relations in American history† He means that these terms do not have clear distinctions and have evolved over time. In paragraph 2, he writes that ethnicity can become racialized â€Å"whenever distinctive group characteristics†¦are used as the basis for a status hierarchy of groups who are thought to differ in ancestry or descent.† What does Fredrickson mean by â€Å"the burden of ‘otherness’†? Summarize the ways in which racial categories and definitions of â€Å"whiteness† have changed during the course of American history.   Fredrickson means that throughout the course of American History being labeled as an â€Å"other,† has changed. From the 1860s to the 1920s there were different kinds of race quotas on immigration. Definitions of â€Å"whiteness have changed drastically as we can observe in Fredrickson’s writing. In the late 19th and early twentieth centuries the ideas of euguenics, scientific racism, and social Darwinism, all accumulated in different definitions of â€Å"whiteness.† Fredrickson writes that â€Å"In the minds of many(during the period of the 1860s to the 1920s) true americans were not merely white but also Northern European†¦.some even harbored doubts about the full claim of â€Å"whiteness† of swarthy immigrants from southe rn Italy.† What are some of the ways that ethnic hierarchy has been eliminated? In what ways does it persist, according to Fredrickson? What evidence can you think of that would support or challenge this contention? Ethnic hierarchy was almost wholly eliminated after WWII among White people of different European background as well as Jews. The ethnic hierarchy shifted from ethnic background to color. After the civil rights movement in the 1960s, most of the ethnic hierarchy had been eliminated. Fredrickson says that it still persists in the ghettos, indian reservations, and barrios. I agree with Fredrickson on the assertion that Ethnic hierarchy still exists in America  today. For example, Unequal treatment by law enforcement and the ethnic targeting among the African American community is still present today. Fredrickson writes that â€Å"assimilationist thinking is not racist in the classic sense† (para. 9) — thereby implying that such thinking may be racist in some other sense. What does he mean by this? Do you agree? Fredrickson means that assimilationism tries to force one culture into accepting the â€Å"superiority, purity, and unchanging character of the dominant culture.† He gives an example of the â€Å"Native American cultural genocide† in regards to assimilationism. I agree, Assimilationism can force a culture to throw away part of its identity, values, and traditions. How does Fredrickson distinguish cultural pluralism from assimilation? How did earlier forms of pluralism differ from the current concept of multiculturalism? Fredrickson writes â€Å"†Unlike assimilationists, cultural Pluralists celebrate differences among groups, rather than seek to obliterate them.† According to Fredrickson, pluralism differed from Multiculturalism, â€Å"Multiculturalism operated on assumptions that were similar to those of the cultural pluralist tradition, except that the color line was breached and the focus was shifted from the cultures and contributions of diverse European ethnic groups to those of African Americans, Mexican Americans, Asian Americans, and Native Americans. Why does Fredrickson reject the claim that an emphasis on ethnic identity threatens the unity and stability of American society? Why does a Euro-American backlash against ethnic diversity pose a greater risk in his view? Have you observed any recent examples of either divisiveness or backlash? Compare your observations with those of classmates. He rejects the claim that emphasis on ethnic identity threatens the unity of American society because American society is made up of different ethnic backgrounds. backlash against ethnic diversity poses a greater risk because it provides more room for racism or discrimination.

A Short Story - 1418 Words

Karjon moved on from the Birthing Centre out to the perimeter of the Hive. He could see the great barren land ahead of him and the lowly looking buildings behind him. This reminded him of his own Hive’s layout. The more important, elaborate and ornate structures were at the centre of the Hive. The edge was reserved for the slum areas. However all of this was above ground. It intrigued him somewhat that the Religious Hive had a slum area at all. Everyone in this Hive were well off, praying to God, weren’t they? Well no time to ponder social castes. He was on a mission. He firstly looked around to see if anyone was noticing him. Moving out to the extremities of the Hive was not only risky but could draw undue attention. He would have a†¦show more content†¦Meanwhile Murfon and Tamblin had returned to the Trainee Centre. They were greeted warmly and gave apologies for Karjon’s absence. It did not take too long for a small band of them to form an audience waiting for another probing debate. Their new friend Quagon seemed to be organising everyone. Murfon nodded to Tamblin to indicate that now may be the time to reveal the information about the sky beyond God’s World. The two had discussed earlier if they should really do it and what consequence might ensue. Telling them about it without proof yet is one thing, suggesting something that would be construed as blasphemy is quite another. But they were resolute to discover if the Trainees knew anything about it or knew someone who knew something about it. If neither, it might prove helpful to have a theoretical discussion about it anyway. From the last meeting they learnt that these Trainees were very intelligent and quite open to different ideas. For the Trainees, they had a secret outlet from their strict doctrine. So they sat eagerly awaiting what the two had in store for them. â€Å"Have you ever wondered what lies beyond God’s World?† Murfon started quite bluntly. â€Å"Obviously there is nothing beyond God’s World. It is the only thing above us. We’ve known that all our lives.† Came one reply with several grunts of agreement.
