Map of Natural Radioactivity

Map of Natural Radioactivity Many people do not realize that radioactivity occurs naturally on Earth. In fact, it is actually quite common and can be found virtually all around us in the rocks, soil and air. Natural radioactivity maps may look quite similar to normal geologic maps. Different types of rocks have specific levels of uranium and radon, so scientists often have a good idea of the levels based on geologic maps  alone.   In general, a higher altitude means a higher level of natural radiation from cosmic rays. Cosmic radiation occurs from the suns solar flares, as well as subatomic particles from outer space. These particles react with elements in the Earths atmosphere as they come into contact with it. When you fly in an airplane, you actually experience significantly higher levels of cosmic radiation than from being on the ground.   People experience different levels of natural radioactivity based on their geographic locale. The geography and topography of the United States is very diverse, and as you may expect, levels of natural radioactivity differ from region to region. While this terrestrial radiation should not concern you too much, it is good to be aware of its concentration in your area.   The featured map was derived from radioactivity measurements using sensitive instruments. The following explanatory text from the US Geological Survey  highlights a few of the areas on this map that show especially high or low levels of uranium concentration. Radioactive Areas of Note Great Salt Lake: Water absorbs gamma rays so it shows as no data area on the map.Nebraska Sand Hills: Wind has separated the lighter quartz from the clay and heavier minerals that usually contain uranium.The Black Hills: A core of granites and metamorphic rocks high in radioactivity is surrounded by less radioactive sedimentary rocks and gives a distinctive pattern.Pleistocene glacial deposits: The area has low surface radioactivity, but uranium occurs just below the surface. Thus it has a high radon potential.Deposits of glacial Lake Agassiz: Clay and silt from a prehistoric glacial lake have higher radioactivity than glacial drift surrounding it.Ohio Shale: Uranium-bearing black shale with a narrow outcrop zone was scooped up and spread over a large area in west-central Ohio by glaciers.Reading Prong: Uranium-rich metamorphic rocks and numerous fault zones produce high radon in indoor air and in ground water.Appalachian Mountains: Granites contain elevated uranium, particularly in fault zones. Black shales and soils above limestone also contain moderate to high levels of uranium. Chattanooga and New Albany Shales: Uranium-bearing black shales in Ohio, Kentucky, and Indiana have a distinctive outcrop pattern clearly defined by radioactivity.Outer Atlantic and Gulf Coastal Plain: This area of unconsolidated sands, silts, and clays has one of the lowest radon potentials in the United States.Phosphatic rocks, Florida: These rocks are high in phosphate and associated uranium.Inner Gulf Coastal Plain: This area of the Inner Coastal Plain has sands containing glauconite, a mineral high in uranium.Rocky Mountains: Granites and metamorphic rocks in these ranges contain more uranium than sedimentary rocks to the east, resulting in high radon in indoor air and in ground water.Basin and Range: Granitic and volcanic rocks in the ranges, alternating with basins filled with alluvium shed from the ranges, give this area a generally high radioactivity.Sierra Nevada: Granites containing high uranium, particularly in east-central California, show as red areas.Northwest Pacific Coastal Mountains and Columbia Plateau: This area of volcanic basalts is low in uranium.

Marin Luther King essays

Marin Luther King essays Martin Luther King Jnr. was born on 15 January 1929. His father, Daddy King, was the pastor at the Ebenezer Baptist Church. King took his duties beyond serving his church, and was involved with the National Association for the Advancement of Colored People. This was probably the influential thing in kings (jnr.) early life that later made him accomplish what he did. King first met racism at the age of six, when a white friends father said that they could no longer play together because King was coloured. His own parents explained about slavery and also made an important point: Dont let it make you feel you are not as good as white people. Kings progress through school was fast. At 15 he went to Morehouse College, a theological college in Connecticut. Here, he expressed doubt about the value of religion, but was eventually convinced of its relevance to the civil-rights struggle. At 19 he was ordained. With a degree in sociology he went to Crozer Theological Seminary in Chester, Pennsylvania, to study for a degree in divinity He came top of his class and graduated in 1951. He went on to study for a doctorate in systematic theology at Boston University. After completing his studies, King felt that he should return home. Accompanied by his new wife, Coretta, he began work at Dexter Avenue Baptist Church in Montgomery Alabama. The church was attended mainly by the educated black middle class. Once installed, he set about organizing his congregation. His interest in the community and his effective oratory made him a popular and respected figure. Montgomery, in the Southern heartland, had strict segregation laws; for example, rules about what black passengers could and could not do on buses. Resentment at these rules ran high. On 1 December 1955, Rosa Parks refused to give up her seat to a white and was taken to jail. On 5 December the local black ministers met to discuss...

Juergen Habermas

Juergen Habermas Best Known For:    A philosopher in the tradition of critical theory and pragmatism.His theory on the concepts of â€Å"communicative rationality† and the â€Å"public sphere.†His work on the concept of modernity.    Birth: Jà ¼rgen Habermas was born June 18, 1929. He is still living. Early Life: Habermas was born in Dusseldorf, Germany and grew up in the postwar era. He was in his early teens during World War II and was profoundly affected by the war. He had served in the Hitler Youth and had been sent to defend the western front during the final months of the war. Following the Nuremberg Trials, Habermas had a political awakening in which he realized the depth of Germany’s moral and political failure. This realization had a lasting impact on his philosophy in which he was strongly against such politically criminal behavior. Education: Habermas studied at the University of Gottingen and the University of Bonn. He earned a doctorate degree in philosophy from the University of Bonn in 1954 with a dissertation written on the conflict between the absolute and history in Schelling’s thought. He then went on to study philosophy and sociology at the Institute for Social Research under critical theorists Max Horkheimer and Theodor Adorno and is consider a member of the Frankfurt School. Early Career: In 1961, Habermas became a private lecturer in Marburg. The following year he accepted the position of â€Å"extraordinary professor† of philosophy at the University of Heidelberg. That same year, Habermas gained serious public attention in Germany for his first book Structural Transformation and the Public Sphere in which he detailed the social history of the development of the bourgeois public sphere. His political interests subsequently led him to conduct a series of philosophical studies and critical-social analyses that eventually appeared in his books Toward a Rational Society (1970) and Theory and Practice (1973). Career and Retirement: In 1964, Habermas became the chair of philosophy and sociology at the University of Frankfurt am Main. He remained there until 1971 in which he accepted a directorship at the Max Planck Institute in Starnberg. In 1983, Habermas returned to the University of Frankfurt and remained there until he retired in 1994. Throughout his career, Habermas embraced the critical theory of the Frankfurt School, which views contemporary Western society as maintaining a problematic conception of rationality that is destructive in its impulse toward domination. His primary contribution to philosophy, however, is the development of a theory of rationality, a common element seen throughout his work. Habermas believes that the ability to use logic and analysis, or rationality, goes beyond the strategic calculation of how to achieve a certain goal. He stresses the importance of having an â€Å"ideal speech situation† in which people are able to raise moral and political concerns and defend them by rationality alone. This concept of the ideal speech situation was discussed and elaborated on in his 1981 book The Theory of Communicative Action. Habermas has gained a great deal of respect as a teacher and mentor for many theorists in political sociology, social theory, and social philosophy. Since his retirement from teaching he has continued to be an active thinker and writer. He is currently ranked as one of the most influential philosophers in the world and is a prominent figure in Germany as a public intellectual, often commenting on controversial issue of the day in German newspapers. In 2007, Habermas was listed as the 7th most-cited author in the humanities by . Major Publications: Structural Transformation and the Public Sphere (1962)Theory and Practice (1963)Knowledge and Human Interests (1968)Towards a Rational Society (1970)Legitimation Crisis (1973)Communication and the Evolution of Society (1979) References Jurgen Habermas - Biography.

But for the same reason, I support Mr. Barrack Obama who is more flexible. Further I learnt about my father’s influence on me, when I read about the concept of political socialization. I learnt that political socialization is a concept in political study. It mainly deals with the psychological development processes by which a man, in modern society, adopts and internalizes various features, of a political culture, such as political attitudes, political beliefs, political values, behavior patterns and habits. Indeed the internalization of these political features teaches a man to belong to a political community. Therefore, it basically determines the doctrinal and behavioral aspects of a political community. Indeed political socialization is the summation of all the evaluative, cognitive and affective internalization and orientation -of a man’s consciousness in his or her childhood and adolescence- towards a political system. The political socialization starts from one’s childhood. A child’s political socialization begins with th e influence of various agents such â€Å"parents, family, Friends, Teachers, Media, Genders, Religion, Race, Age, and Geography†. They play very fundamental roles to impact a child’s political beliefs. These agents are often classified into two groups: primary group and secondary group. Political socialization of a man is â€Å"determined by the face-to-face interactions of a man with the primary agents† such as parents, family members, friends, etc. The primary agents are supposed to be in direct contact with the primary.

Kenya - Essay Example Most of the arts and crafts made from woodcarvings, kisii soapstones and clay. The arts, jewellery, traditional clothes, and crafts signify decoration, adornment and traditional lifestyles of the communities (Sobania 22). Ethnic communities like Samburu, Turkana and Maasai prefer physical beauty in their artistic expressions. Samburu and Maasai communities wear traditional dressings that are decorated with traditional beads and animal skins. The decoration beads signify social status and different stages of passage and initiation.

Contemporary issue in the Economic and Political Environment of the UK Essay

Contemporary issue in the Economic and Political Environment of the UK Britain and the Euro Should we join or not - Essay Example And now I will try to give you an accurate account of the economic situation in the United Kingdom. (Minford) Chancellor of the Exchequer of the UK thinks that the country is not ready to join the European currency. Tony Bluer is of the some opinion. He is known to be a supporter of the European fusion, but he has not made the official statement yet. But still the decision has not been taken. (Minford) Observers say that Chancellor of the Exchequer isn't eager to introduce the country into the European zone. Prime Minister and the whole Labour party like the idea of the economical reunion with the continental Europe. There are some reasons for it. Firstly, Britain wants to be the leader of the EU, and for it the country should have the same currency as the whole organization has. (Marsday) Secondly, there is a probability of split between the members of the Labour party. And it is not profitable for the Prime Minister. Thirdly, the Conservative party can use antagonisms among the Labour party leaders which exist. From the economic point of view it is profitable for Britain to join the Euro. But the most suitable moment for it is when the Pound will be a bit closer to the Euro. In such a way the economy of the country will not feel a big strike. Otherwise, there will be a recession of the economy. But still, the nation won't feel it, because of the high development of the social pr ogram in the country. But the competing the Conservative party is strongly against it. They lost the trust of people, because of being against joining Britain the EU. Their most influential argument is the historical currency of the country. (Marsday) Their motto is: Let's preserve the Pound. Almost half of the country supports this idea. (Minford) The Conservative Party says that people must decide whether to change the national currency or not. A national referendum must show what to do with the problem which exists. The leader of the Party is sure that the country can successfully do without the Euro. He says that British people do not want to join the Euro. People know that it is a political decision, and the economic policy is not related to it. He adds that Tony Bluer just wants to choose the suitable moment and win the referendum. The Head of the Chamber of the Commerce, David Frost, says that the Government will decide whether to join the Euro or not, but later. However the Government should denote their actions for investors to know what to do with their capital formations and what to do next. The striking example of it is the Japanese corporation Toyota. It is one of the biggest foreign investors in Britain. (Marsday) At first, Toyota and almost all the other Japanese companies wanted Britain to introduce a new European currency. They were alarmed what would be with their investment. (Minford) However, now the Head of the Japanese corporation says that Toyota has a stable position in the country, and is not going to enlarge their capital investment. The corporation is not troubled
