Atomic Structure essays

Atomic Structure essays The nucleus has more than 100 protons and more than 150 neutons, the nucleus is a very small part of an atom. Both the atom and the necleus can be thought of as spheres. Then both volumes of the atom can be compared with the volume of the nucleus alone, because the volume of a sphere is proportional to the cube of its radius. The space outside the nucleus is occupied only by electrons. The observation has led to the empty space concept of matter. Ernest Rutherford , a British physicist, performed an experiment that strongly suggested that the positive charge of an atom located in a very small nucleus. Rutherforth's experiment made use of polonium, a radioactive element that gives of positvely charged particles. These particles are called alpha particles. A steam of these particles was allowed to strike a thin sheet gold or copper. Behind the metal foil was a fluorescent screen. This diagram showes what Ernest Ruthefold and his colleges observed. Most of the alpha particles passed through the metal foil with very little interference. Each time one of the alpha particles hit the flourescent screen, a flash of light was given off.Few particles did not pass though the foil. Rutherford found that a very few alpha particles was deflected by more than 90Â °. Because of these experiments , he made a nuclear model of the atom, which described the atom with its nucleus, and an atoms lack of energy charge. An atom is electrically neutal because it has negatively charged particles,or electrons,that balance the positive charge of the nucleus. The electrons are present in the empty space surrounding the nucleus. The atomis number is the number of positive charges in the nucleus of an atom. Each proton carries one positve charge. The atomic number represents the number of protons in the nucleus of an atom. The atomic number never changes. The mass of an element is given units called atomic mass uni ...

Hagar Currie Shipley Essay Example | Topics and Well Written Essays - 750 words

Hagar Currie Shipley - Essay Example She does manage, however, to marry the exciting, thrilling and rebellious part of the human spirit to the hard-working, achieving and socially acceptable side finally, in her grandchildren. Through all of this, Laurence makes Hagar an unforgettable character because we learn through the book she is a real person with wants and needs and dreams. As the reader learns, Hagar Shipley's dreams were so simple, she didn't even know what they were until it was almost too late. At three crucial points in the book, Hagar speaks about the things she wants. The first time is a bluff. When Hagar returns from two years at school "down East," she confronts her father about what she plans to do. "I want to teach. I can get the South Wachakwa school," she defiantly tells him (p. 43). But it is as though she expects a conflict, and is even looking forward to one. She knew that her father was just like her -- very stubborn and blunt -- and she goes in to the confrontation with full knowledge of his response. What it appears that Hagar wants is not to teach, but some affection from her father, or even just some sign that he is capable of affection. The only time Hagar ever saw him express anything resembling an emotion was when she hid in the chokecherry bush at the cemetery as he and No-Name Lottie Drieser's mother apparently terminate an affair (or attempted affair) after the death of her husband. During the confrontation with her father, he reaches an even higher level of rage, which he takes out on the newel post, the knobby carving at the top of the wooden stair railing. He wrings the neck beneath the head-like newel post like the neck of a person. When he expresses, however briefly, that he needs her around, he grips her hand so tightly, it hurts. Instead of recognizing their need for each other, and for the simple expression of affection that is natural for a father and daughter, the encounter ends badly. Hagar pulls away as though she had just touched a hot stove. She has gotten what she wanted: a sign that she is important to him, but in all her pride, cannot go after him when he goes outside. In this she is just like him; they are both proud in destructive ways. This first simple dream, to be loved by one's parent, remains out of her reach because Hagar lets it remain there. At this point in the book, three years pass quickly. Hagar has done what her father wanted, ex cept she rejects all his suitors. In short order, she meets Brampton Shipley and embarks on an ill-advised marriage that flouts everything she was raised to believe. The next time Hagar speaks of a dream, it is many years later when she has returned to the Shipley home while her estranged husband Bram is dying. She insists that what she wants is for her younger son John to be happy. By this point, Hagar has identified John as the true heir of her father, rejecting her hard-working but plain older son Marvin. She has refused, all these years, to see that John is like Bram, and John is the one who must tell her. She had a clue many years before when she gave John her father's clan pin and he just sticks it in his pocket. John later trades the pin for a worthless knife, which ultimately is worth only a pack of cigarettes. The sightless stone angel cannot be expected to see clearly, but the relentlessly prideful Hagar just refuses to. " 'You always bet on the wrong horse,' John said gently. 'Marv was your

Different types of Asthma Essay Example | Topics and Well Written Essays - 1000 words

Different types of Asthma - Essay Example Asthma in children can be hard to diagnose. There are other conditions that can have similar symptoms and sometimes these conditions can be combined with asthma. Some common conditions with the same symptoms are rhinitis, sinusitis, acid reflux, vocal cord dysfunction, and respiratory tract infections, such as bronchiolitis and RSV.Doctors use the same tests to diagnose asthma in children ages 5 and up as they do with adults. The test is called a spirometry, it measures how quickly and how much air your child can exhale. The doctor will also try to find out if the asthma is caused by the child’s allergies. An allergy skin test will be given to check for allergy-causing substances, such as animal dander, mold or dust mites, and observed for signs of an allergic reaction.The doctor will make an asthma action plan and depending on the type and severity of asthma in the child the doctor might prescribe a medication. The purpose of treating asthma is to prevent symptoms and to trea t an asthma attack that is in progress. The goal after treatment is that the child will have little to no symptoms, fewer flare-ups, no limitations on daily activities, and few side effects from the medications.  Long-term medications will be used to treat the inflammation that causes the symptoms of asthma. The doctor would prescribe an inhaled corticosteroid, such as Qvar. Leukotriene modifiers such a Singulair will help to prevent the asthma symptoms for up to 24 hours. Sometimes a medication will be needed that is combined inhaler.

Idealism Against Realism In International Policy Politics Essay

Idealism Against Realism In International Policy Politics Essay The history of the modern political science is to a great extent the story of continuing struggle between the two paradigms, the two belief systems on the basis of international order and means of stabilizing international relations. Representatives of one of them, the tradition of which dates back to Stoic philosophy and the biblical postulates of the unity of the human race, the views of the medieval theologian F. de Vitoria and outstanding thinker of the 18th century Immanuel Kant, believe that a stable international order can be built and maintained only in the light of universal moral principles and based on these laws (Pijl 3-34). In practice, this political paradigm the paradigm of political idealism finds its fullest expression in the policy developed under the leadership of President Woodrow Wilson, particularly in his program of permanent universal intergovernmental organization the League of Nations, which was to become a guarantor and an instrument of the new internati onal order after the First World War. Further, the paper covers the idea that the political views of Wilson significantly differed for the postulates of realism and need to become more realist in applying them to the contemporary politics. The main ideas of a paradigm of political realism Wilson opposed can already be found in The History of the Peloponnesian War by the ancient Greek historian Thucydides, the views of the Italian political philosopher Machiavelli, English philosopher Thomas Hobbes in his theory of the natural state, his fellow countryman David Hume, who asserted a theory of political equilibrium, German General Carl von Clausewitz and others (Pijl 3-34). Already in 1932, American theologian R. Niebuhr in his book Moral Man and Immoral Society criticized the pacifism of idealists and their short-sightedness in the face of imminent danger of fascism. A relatively independent branch of this area of political thought in the beginning of World War II becomes geopolitics (by Mackinder, Spykman, Mahan, and others) (Keohane and Nye 72-80). The founding father of the theory of political realism is considered to be the University of Chicago professor Hans Morgenthau. Already the first edition of his book Politic s among Nations. The struggle for Power and Peace in 1948 caused wide interest in science and the political environment not only in the U.S. but also in other Western countries (Pijl 3-34). In contrast to political realists, Woodrow Wilson and other representatives of the idealist direction are convinced that the states are not only non-singular, but also not major international actors. They believe that this role is played by international organizations (in this case, intergovernmental). At the same time, among the main problems of the theory and practice of international politics, realists point out the problems of implementation and protection of national interests, rivalry and balance of power in the global arena, strategies for achieving and maintaining state power (not least in its military dimension), conclusion and revision of interstate unions, depending on changes in the geopolitical (geostrategic) situation, etc. Idealists emphasize the existence of universal, human interests, values and ideals, the inalienable rights of human beings, the need for a comprehensive system of collective security in order to preserve and protect them. And while the political real ists insist that the major international processes are conflicts, the idealists are talking about negotiations and cooperation. Finally, according to political realists, the immutability of human nature and the whole experience of international relations show that the hopes for changing their nature and the creation of a new world order based on the rule of law and respect for the individuals interests are no more than a utopia. Idealists, by contrast, believe in achieving world harmony, the deliverance of mankind from the deadly and devastating armed conflict in the creativity of universal morality and international law (Keohane and Nye 113-142; Pijl 3-34; Mead). However, the confidence in the fact that the United States is intended to serve as an engine for spreading of democracy, free markets and individual freedom is the stable foundation for the interaction of the USA with the world. The fact that such bitter rivals as President Woodrow Wilson and Theodore Roosevelt equally widely considered American interests in the world, believing that the fate of the United States is inextricably linked to the character and conduct of countries around the world, underlines the prevalence of this ideology. Woodrow Wilson declared that all the nations are engaged in the life of the whole world, whether they like it or not; and thus, anything that affects mankind is inevitably our affair (Kennedy 81-84). Roosevelts idea of the global role of the USA was equally far-reaching; he stated that the country should accept the idea of international morality, and thus, be committed to doing everything possible to achieve fairness and integrity of the humanity as a whole, but should also feel obliged to judge all other nations by their actions in each separate case (Mead). This is, however, a clear evidence that the nature of American foreign policy is determined by serving to ideals, i.e. by incorrigible idealism, which can only be a part of a dynamic and complex process, while American foreign policy must constantly be balanced with sober strategic imperatives. Still, it can be said that sometimes Wilsons idealism was factually combined with the hard realism. For example, regretting over the reports on mistreatment of Armenians by Turks, Wilson resisted loud demands to declare war on the Turks, fearing to endanger the American missionary presence in the Middle East. Indeed, the reluctance of the United States to send American troops to support the nascent Armenian state after World War I contributed to the rapid collapse of Armenia (Mead). The way Wilson conducted the war also ruled out any hint on his starry-eyed idealism, as it was necessary to give effect to the power of the American military machine or the principle of power without limits and without measure proclaimed by Wilson. Thus, in the American involvement in World War I, we can see a strategy built by a hybrid of narrowly defined interests and deep-seated American principles (Kennedy 97-101). But in general, the very name of Woodrow Wilson has become a synonym to American idealism. His intention to make the world safe for democracy stimulated the American community, when the isolationist nation entered World War I. His speeches for self-identification generated deep resonance among nationalists throughout the world, and Wilson himself was considered as practically messianic figure (Kennedy 213-15; Mead). Modern Wilsonians believe that the U.S. should deal with international problems in close cooperation with other states and within the strict framework of international law. U.S. should also promote and disseminate widely the idea of democracy (Fukuyama 55-59). The process of globalization has played in this case the crucial and positive role. Wilsonian ideology is nowadays shared by most congressional Democrats. The modern interpretation of this school (neo-liberalism or transnationalism) is associated with the works of Robert Keohane and Joseph Nye. In neoliberal version, the major attention is focused on the processes of interdependence in the modern world and the growing role of non-state actors in world politics. Finally, we should rethink the question of what place should be taken by the spread of democracy in U.S. foreign policy. Perhaps the most false interpretation of the lessons the war in Iraq would be a complete rejection of neoconservative ideas, coupled with a tendency towards isolationism and realism in its cynical interpretation, because as a result, U.S. allies would consequently be friendly-minded authoritarian regimes (Fukuyama 134-37). Woodrow Wilsons idealistic policy, which builds international relations taking into account how other countries treat their own citizens, should generally be recognized correct, but should also be provided with greater realism, that was still lacking at the beginning of the 21st century.

The Impact of World War I and President Wilson on Womens Suffrage Essa

The Impact of World War I and President Wilson on Women's Suffrage On November 11, 1918, the armistice was signed that ended World War I. The Allies, including the United States, had won. The very next year the nineteenth amendment, guaranteeing women the right to vote passed Congress and in 1920 went on to be ratified by the states. The women of the United States had also won. This timing was not mere coincidence. The war had a profound impact on the suffrage movement. It became the central issue in women’s activism for a federal suffrage amendment. In turn, the women used it as a plea and a bargaining chip for the support of politicians, specifically President Woodrow Wilson. Wilson was a pivotal figure in the last two years of the fight for women’s suffrage, 1917 and 1918. It was his influence on suffrage that ultimately won women the vote by his support of the federal amendment as an emergency war measure. Wilson’s support for a federal amendment was remarkable because before the war, he had not considered womenâ⠂¬â„¢s suffrage a federal amendment issue. Other historians rightfully credit Wilson for his all-important support of the federal suffrage amendment. Yet some do not document the evolution of his ideology on the issue, and those who do not go far enough. For years, Wilson had held the position that women’s suffrage was a states’ rights issue. On August 15, 1912, as Wilson was campaigning in Massachusetts, Governor Eugene Noble Foss wrote him to ask about his position on women’s suffrage. The Governor stated that he had been under pressure from local factions of the women’s movement to learn Wilson’s thoughts on the issue. Two days later Wilson responded and spelled it out for the Governor. â€Å"I must s... ...unardini and Steinson clearly shows Wilson’s important influence on the suffrage movement. It even conveys the fact that Wilson had not always supported a federal suffrage amendment, but neither Lunardini nor Steinson goes far enough in explaining the why and the how of his conversion. Through his correspondence with leaders in the women’s movement and other politicians, Wilson abandoned his previous position of suffrage as a state’s rights issue. He came to believe in a federal amendment for a variety of philosophical as well as practical concerns. This conversion and its process were important occurrences in the course of American women’s history. Without Wilson’s support it is impossible to tell how much longer the suffrage battle would have worn on, and his support would never have come about if it were not for all these influences on his evolving ideology.

Discussion Bill of Rights Essay

The Bill of Rights is the collective name for the first ten amendments to the United States Constitution. The Bill of Rights lists freedoms not specifically identified in the main body of the Constitution. These freedoms are freedom of religion, freedom of speech, a free press, and free assembly; the right to keep and bear arms; freedom from unreasonable search and seizure, security in personal effects, and freedom from warrants issued without probable cause; indictment by a grand jury for any capital or â€Å"infamous crime†; guarantee of a speedy, public trial with an impartial jury; and prohibition of double jeopardy. In addition, the Bill of Rights reserves for the people any rights not specifically mentioned in the Constitution and reserves all powers not specifically granted to the federal government to the people or the States. Originally the amendments applied only to the federal government, however, most were subsequently applied to the government of each state by way of the Fourteenth Amendment, through a process known as incorporation. On June 8, 1789 Representative James Madison introduced a series of thirty-nine amendments to the constitution in the House of Representatives. Among his recommendations Madison proposed opening up the Constitution and inserting specific rights limiting the power of Congress in Article One, Section 9. Seven of these limitations would became part of the ten ratified Bill of Rights amendments. Ultimately, on September 25, 1789, Congress approved twelve articles of amendment to the Constitution and submitted them to the states for ratification. Contrary to Madison’s original proposal that the articles be incorporated into the main body of the Constitution, they were proposed as â€Å"supplemental† additions to it. On December 15, 1791, Articles Three–Twelve, having been ratified by the required number of states, became Amendments One–Ten of the Constitution. The Bill of Rights has had much judicial impact for 150 years of its  existence, but was the basis for many Supreme Court decisions of the 20th and 21st centuries. One of the first fourteen copies of the Bill of Rights is on public display at the National Archives in Washington, D.C.
