Generals Die in Bed - Plot Essay Example for Free
Generals Die in Bed Plot Essay When he thought war contained glory and glamour, he finds himself wrong when his comrades start to die, beginning with Brown. A while later, he is emotionally affected when he kills a German with his bayonet. His emotional status worsens when another of his friend dies. The narrator then goes on leave for 10 days in England, where a prostitute makes him forget about the war. When he comes back, an attempt to raid the Germans takes place where the rest of his friends, except Broadbent dies. The general tells the new team that the Germans sank a hospital ship, and organizes another raid, this time to kill everyone. The narrator has wounded his foot, and discover that Broadbent was mortally wounded too. Broadbentââ¬â¢s leg is hanging by a string of flesh, but then dies by blood loss. Then the war is over. The recruits are told that the general lied, the Germans didnââ¬â¢t sink a hospital ship. It was a ship filled with weapons. He then realizes war is basically a chess game for the generals, and the soldiers are just young boys, listening to the orders, with meaningless ideals Wikipedia

Americaââ¬â¢s Foreign Policy and the Cold War Essay -- American History Go
Americaââ¬â¢s Foreign Policy and the Cold War The role of America at the end of World War II was where the origins of policing the world originate. America had been engaged in a very costly war in terms of dollars as well as lives. But, despite the expense the United States came out of World War II better than any other nation that was involved. The Second World War was a battle between the Allied and Axis Powers. The Allied Powers consisted of the United States, Great Britain, the Soviet Union, China, and France. This war was seen as the fight against Nazi Germany, and therefore resulted in a majority of the battles fought on German and Russian soil. The aftermath left the Soviet Union in bad shape. Close to twenty million Russians had died fighting the war, which accounted for about eight percent of their population. Conversely, none of the fighting was done on American soil, and while the United States suffered in terms of casualties it was nothing compared to the loss Russia had endured. Because the war would not end until t he Axis Powers fully surrendered to the Allied Powers, the United States was forced to use the first atomic warfare in history. The atom bomb would later serve as America's greatest possession. Stalin, the Premier of the Soviet Union had always distrusted the American and English intentions. Because of Stalin's aggression and attitude pertaining to Soviet influence on Europe, the postwar stance on Russia had turned into a standoff. This became the origin of the Cold War. The Cold War, seen as a battle between communism and capitalism, was "in reality a more complex struggle over a broad range of ideological, economic, and strategic issues." Over the next several years the United States would spend more money on military and defense than ever before. Several measures were taken to ensure that the same mistakes at the end of World War I would not be repeated. The first in a series of measures was a postwar conference involving President Truman and the Soviet Foreign Minister, V.M. Molokov, where Truman controlled the entire meeting and basically scolded the Soviet's for not honoring agreements on Poland. Truman "told the Russians just where the got off and generally bossed th e whole meeting." This symbolized America's strong-arm stance against communism and signified the position we would hold throughout the Cold War. The next ... ...rying to get across. Because he saw the country from the inside Kennan also believed the United Sates should " pursue a policy of firm containmentâ⬠¦at every point where the Soviets show signs of encroaching upon the interest of a peaceful and stable world." This opinion and idea of the relationship between the United States and Russia should have been widely accepted by Americans. They backed this idea of aggressive behavior, rather than a passive approach to the Cold War. Conversely, postwar liberal such as Henry Wallace, "a Progressive Party leader, continued to seek cooperation with the Soviet Union and defended the participation of Communists in their organizations." These ideals were quickly silenced. The American majority, being extremely anti-communist, felt relations with the Soviet Union should be harsh and firm. This period introduced American dominance in foreign policy. The ideals of personal freedom and opportunity were the driving forces behind Western philos ophy throughout the Cold War. Not only were these principles showcased, they were set as the benchmark of equality for the human race. Bibliography: COMPTONS ENCYCLOPEDIA COLD WAR;1989 JAMES CORNWELL

Radon Gas Case Study Essay
OBJECTIVE: Build a simple ionization chamber that is capable of detecting fairly low levels of radiation BACKGROUND OF THE STUDY Radon is a cancer-causing gas. It comes from the natural breakdown of uranium in soil, rock and water and gets into the air you breathe. These radioactive materials ââ¬Å"decayâ⬠into lighter elements, emitting energetic sub-atomic particles in the process, and one of those lighter elements is Radon. Since radon is a noble gas, it is chemically inert and doesnââ¬â¢t stay bound in the solid the way itââ¬â¢s parent did. It diffuses right through solids and ends up floating freely in the air. Being a noble gas, radon is fairly harmless, itself. You breathe in some radon with every breath but then you breathe it right back out, since it isnââ¬â¢t chemically active or electrically charged. But radon has a short half-life of only about four days, meaning that about half of it will decay within four days, producing new, even lighter radioactive isotopes of other elements like polonium, lead, and bismuth. Those isotopes keep decaying, until a stable isotope of lead is reached. These radon ââ¬Å"daughtersâ⬠are not noble gasses like radon, they are usually ionized when they are produced, and they will readily stick to anything nearby, like healthy lung tissue. They typically have an even shorter half-life than radon and quickly decay inside the lung, kicking out energetic alpha and beta particles that can cause tissue damage and potentially trigger lung cancer. This unfortunate chain of events is due to the decay chain including a noble gas. Radon gas is considered to be the second leading cause of lung cancer. It can get into any type of building ââ¬â homes, offices, and schools ââ¬â and result in a high indoor radon level. But, we are most likely to get your greatest exposure at home, where we spend most of our time. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Any home traps radon inside, where it can build up. Any home may have a radon problem. This means new and old homes, well-sealed and drafty homes, and homes with or without basements. These are examples where you can find the noble gas: 1. Cracks in solid floors 2. Construction Joints 3. Cracks in walls 4. Gaps in suspended floors 5. Water supply It breaks down into solid radioactive elements called radon progeny. Radon progeny can attach to dust and other particles and can be breathed into the lungs. As radon and radon progeny in the air break down, they give off alpha particles, a form of high-energy radiation that can damage our health. Radon daughters will stick to just about anything they encounter, so they are easily collected by drawing air through a dusting cloth with an ordinary fan. After collecting the daughters for about an hour or two, the radiation being emitted from the cloth due to the further decay of the collected radioactive isotopes can be measured with a simple ionization chamber made from an empty coffee can, a single Darlington transistor, and a digital voltmeter. The deceivingly simple ion chamber is quite sensitive and can detect radon daughters in buildings with radon concentrations below the ââ¬Å"action levelâ⬠recommended by health authorities. A simple ionization chamber is nothing more than a metal can with a wire inside. When a radioactive particle passes through the air in the chamber, many of the molecules of air are ionized, having electrons knocked loose from the outer atomic shells. Applying a positive voltage on the outer can relative to the internal wire, causes these ions to be attracted to the wire and the free electrons to be attracted to the interior wall of the can. This movement of charge is a tiny current that may be amplified to detect the rate at which ions are being generated, and thereby the rate that radioactive particles are passing through the can. The chamber will be detecting mostly betaà particles. BACKGROUND OF THE STUDY Copper is an essential element for all known living organisms, including humans. You need a small amount of copper in your diet to stay healthy. On average, most people will eat and drink about 1,000 micrograms ( à ¼g) of copper per dayââ¬âdrinking water normally contributes approximately 150 à ¼g per day. Levels of copper found naturally in ground water and surface water are typically very lowââ¬âabout 4 à ¼g of copper in one liter (L) of water or lessââ¬âhowever, drinking water may contain higher levels of copper, usually as a result of flowing through copper pipes. High levels of copper can occur if water that is corrosive comes in contact with copper plumbing and copper-containing fixtures. Many factors can make water corrosive for copper pipes: dissolved salts and minerals, bacteria, and suspended solids, such as sand, sediment, and rust. The level of copper in drinking water increases with the corrosivity of the water and the length of time it remains in contact with the plumbing. If the copper level gets too high, the water may have a metallic taste and you might notice blue or blue-green stains around sinks and plumbing fixtures. It will be highest in the morning because the water will have been exposed to the pipes overnight. If you are being served by a public water system, the owner of the utility will have results ofà copper sampling, which is a process that has been done in parts of the water-distribution system. In this chemistry science fair project, you will investigate another possible factor in making water corrosive for copper ââ¬â the pH of the water. You will test the theory that acidic water is more corrosive for copper pipes than non-acidic water. In the procedure, dingy copper pennies will be placed in either plain water or in water with acetic acid (vinegar). You may know that newly minted pennies have bright, shinny copper but over time the copper and air react and the pennies build up a layer of copper oxide on them. The copper oxide is the dull, dark coloration on well-used pennies. In this experiment, if the water is corrosive enough to strip off the copper oxide then you will see the progress of the reaction by watching the pennies go from dull and dingy to bright and shiny. The pennies get shiny because the copper oxide is being stripped off by a reaction, which results in increasing levels of copper in the liquid. Unfortunately, water that is corrosive slowly eats away at the pure copper, as well as at the copper oxide. For houses with corrosive water systems, this can result in elevated levels of copper in the drinking water. On a purely practical level, houses with corrosive water systems might find that their copper pipes are springing leaks, and that the whole house needs to be re-piped with plastic pipes! To measure the amount of copper present in the solutions that are used to clean the pennies, you will perform a color-based chemical test. The chemicals for the test are contained in a small tablet, which is dissolved in water. When the tablet is dissolved, the solution turns reddish-orange. If no copper (or very small amounts of copper) is present, the solution remains reddish-orange. If copper is present, the solution will turn blue.

Media And Its Effects On Society - 1709 Words
Violence is much more socially acceptable in todayââ¬â¢s society than it was hundreds of years ago, which is mostly caused by technological advances. As technology expanded, so did our generationââ¬â¢s tendency for violence. With all the breakthroughs in social interaction using technology, the media has become a large contributor to society. Coinciding with the first amendment to free speech, the media is a very valuable and powerful tool in spreading information when used for important purposes. However, many people abuse this power and sometimes spread the wrong message. Due to the vast amount of people promoting the wrong values, our society suffers the consequences through the immature minds of those who are easily swayed. Therefore, thisâ⬠¦show more contentâ⬠¦Just a few decades ago, producers of a reality show would immediately cut out these violent scenes, but now they have become instigators in order to produce these scenes. But it is not just pseudo-reality tha t affects people; actual violence shown on the news is also a factor. ââ¬Å"Some of the best evidence of a violence effect for news is found in studies of the so-called Marilyn Monroe effectââ¬âthat highly publicized suicides are followed by an increase in suicides among the populace over the course of about two weeks. Collectively, the studies on this relationship suggest that news coverage of suicide produces a 2.5% increase in actual suicidesâ⬠(Huesmann Taylor, 2006). So regardless if it is pseudo-reality or actual reality, violence is prevalent among us, especially in television, because of the massive amount of time people spend watching it. Movies have also played a significant part of the media. Many popular movies are extremely violent. One of the popular movies that came out over the past few years, which is directed towards young teenage audiences, is the Hunger Games. It is about a post-apocalyptic world where a nation is divided into twelve districts. Two young representatives in each district are chosen at
