Primary and Secondary Consolidation Settlement of saturated soils under increased loading consists of two successive phases, commonly referred to as the primary and secondary consolidation phases. The primary consolidation phase is dominated by pore pressure dissipation and effective stress increase; whereas, the secondary consolidation phase is dominated by creep (viscous deformation) at almost constant effective stress. The consolidation settlement consists of two parts. In conventional soil mechanics
human history, the world was introduced to the awesome power of nuclear weapons. Since that time, there have been several different nuclear threats to the world, and one of those threats can be found along the Pacific Rim, in the country of North Korea. Like the dropping of the atomic bombs, it is also known that the North Korean government has admitted to possessing nuclear weapons, and in doing so, it stands as a silent, potential nuclear danger to the rest of the world. To understand this situation
“The world would be a better place if…” Mutual Assured Destruction. Nuclear holocaust. The destruction of whole nations in the blink of an eye. We cannot hide from the threat that nuclear weapons pose to humanity and all life. These are not ordinary weapons, but instruments of mass annihilation that could destroy civilization and end all life on Earth. Nuclear weapons are morally and legally unjustifiable. They destroy indiscriminately - soldiers and civilians; men, women and children; the aged and
Nuclear weapon is a new kind of technology that gives us an unprecedented power over nature and humanity. The technological decisions regarding nuclear weapons will have a huge impact upon all nations around the world and even future generations. “Of all the unprecedented powers in our hands, none is potentially more destructive than nuclear weapons. For forty years we lived with the threat of a nuclear holocaust that could wipe out a large part of humanity and other forms of life” (Barbour,
Biological and Nuclear Warfare Thesis As current problems of terrorism and the war on Iraq, chemical, biological and nuclear warfare (CBW) issues are important and relevant. CBW agents are dangerous, uncontrollable and undifferentiating weapons of mass destructions. Chemical, biological and nuclear weapons are capable of mass destruction aimed at killing masses of people. Using CBW agents comes with many ethical dilemmas and consequential side-effects. Chemical, biological, and nuclear weapons are
neutron, such an element could sustain a nuclear chain reaction.” -------------------------------------------------------------------------------- 1934 Frederic and Irene Joliot-Curie of France discover artificial radioactivity, i.e. the radioactivity of atoms produced in transmutation experiments. Enrico Fermi of Italy irradiates uranium with neutrons. He believes he has produced the first transuranic element, but unknowingly achieves the world’s first nuclear fission.

terms of the electromagnetic spectrum, radio waves are slightly longer than infrared in the wide range of 10-2m to 105m, corresponding to frequencies from 300 GHz to as low as 3 kHz. The application of radio waves in imaging comes from the concept of nuclear magnetic resonance (NMR). NMR, a physical phenomenon utilized to investigate the molecular properties of matter with the use of the absorption of electromagnetic energy, is similar to VHF and UHF television broadcasts (60–1000 MHz) by the placing
Nuclear Iconography in Post-Cold War Culture I wish in this paper to sketch a project involving nuclear iconography and post-Cold War culture. At the heart of this project is the claim that the current historical moment forms a legitimation crisis for the scientific, military, industrial, governmental, and "cultural" institutions whose interests are configured in the design, manufacture, deployment, and "use" of nuclear weapons. Within this moment, a variety of progressive and regressive movements
In Doris Lessing's short story, "To Room Nineteen," the main character, Susan Rawlings, has a drastic change in lifestyle from that of a successful, independent woman with her own apartment, to that of a conventional 1950’s housewife. On the other hand, her husband has the freedom to work outside of the house and frequently visits social events, still living the life of a single man. Although Susan finds life dull with her new lifestyle, she tolerates these gender roles, until her husband takes
Indian Nuclear Weapons: Costs vs. Benefits The history of Indo-Pakistani relations has been a dominated by turbulence and bitter rivalry. After the partition in 1947, millions of people migrated to their new home in either the Islamic state of Pakistan or the secular state of India. Only two weeks after independence, India and Pakistan fought a war over Kashmir in 1948. India and Pakistan fought two more wars with each other in 1965 and 1971, with the latter resulting in the creation of Bangladesh
Environmental Effects of a Nuclear War Imagine the heat of millions of degrees, the immediate destruction of thousands of acres, and the deaths of hundreds of thousands of lives. Now imagine all of that times a thousand. There you have a nuclear war, the explosion of a thousand or more nuclear bombs on the earth. That is what is estimated would be a nuclear war. All of that power packed in relatively small(considering the power they unleash) bombs. The results of a nuclear war would be devastating
The Effects of the Chernobyl Accident on International Actions Concerning Nuclear Power Early in the morning of April 27, 1986, the world experienced its largest nuclear disaster ever (Gould 40). While violating safety protocol during a test, Reactor 4 at the Chernobyl power plant was placed in a severely unstable state, and in a matter of seconds the reactor output shot up to 120 times the rated output (Flavin 8). The resulting steam explosion tossed aside the reactor’s 1,000 ton concrete
Nuclear Power As our population increases, so will our demand for electricity. Air conditioners, computers, televisions, microwaves, and many other appliances have become necessities for Americans. All methods of producing electricity have drawbacks. As the earth becomes warmer, we must look for ways to decrease our use of fossil fuels. There are several ways to produce electricity without releasing air pollution. The most feasible method at this time is nuclear energy. Nuclear energy presents
Nuclear Energy: Uranium Fission Thousands of years ago human beings learned to make fire. By collecting and burning wood they were able to warm themselves, cook food, and manufacture primitive tools. Later, the Egyptians discovered the principal of the sail. Even more recent was the invention of the water wheel. All of these activities utilize various forms of energy-biological, chemical, solar, and hydraulic. Energy, the ability to do work, is essential for meeting basic human needs, extending
Moral Risk and Nuclear Weapons See the Cat? See the Cradle? "'See the cat?' asked Newt. 'See the cradle?'" (Vonnegut- 183). The day the atomic bomb dropped, August 6, 1945, was the day in which Newt Hoenikker's father tried to play a game with him. Felix, one of the scientists who had helped create the weapon, wanted to play cat's cradle. It is a game played with string looped over the fingers. After a series of movements, one is supposed to be able to see what appears to be a cradle shape
Since the deployment of nuclear weapons in Hiroshima and Nagasaki in Japan, the world has been threatened by nuclear weapons. Although there has not been a nuclear accident, the risk of having one is not impossible. Presently the world has enough nuclear warheads to wipe out all civilization. As technology advanced, more sophisticated and deadly nuclear weapons were built. More countries have nuclear capabilities than there were 50 years ago. As dangerous as nuclear weapons may seem, many have
Compare Nuclear Fusion vs. Nuclear Fission Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In
In June, French President Jacques Chirac revealed that nuclear tests would be conducted in the Pacific at the Mururoa coral atoll. These tests, Chirac, stated, would consist of eight nuclear explosions in a tunnel 1,800 to 3,000 feet below Mururoa beginning in September up until May 96. Chirac declares that these tests are necessary for computer simulation in the future. France has been bombarded with criticism, not only from environmental activists, but also from political standpoints. Japan and
Nuclear weapons are the most powerful and destructive technology ever created. From the first notion that nuclear technology could be harnessed to create a bomb, massive amounts of time and energy (as well as government funding) have been invested in further increasing the destructive yield of nuclear weapons. The process of development was carried out independently by governments worldwide. Despite the segregation of groups of scientists and secrecy surrounding their discoveries, design strategies
Personal Statement: Interests, Experiences, and Goals in Nuclear Engineering Money and fame do not motivate my goals. Engineering in all forms is a field of innovation and invention. Aspirations of any great engineer should be to introduce to the world a new idea, product, or service that will make people happier and the environment safer. Success in these challenges is a reward greater than any dollar amount or public recognition. Engineers bring societies to new levels of civilization through
