Chernobyl, Ukraine - Nuclear Power Plant Meltdown :: essays research papers

Chernobyl, Ukraine Nuclear Power Plant Meltdown   Ã‚  Ã‚  Ã‚  Ã‚  The accident at the Chernobyl Nuclear Power Plant in Ukrainian produced a plume of radioactive debris that drifted over parts of the western USSR, Eastern Europe, and Scandinavia. The accident, which occurred on April 26, 1986, was the worst nuclear power accident in history. Large areas of the Ukrainian, Belorussian, and Russian republics of the USSR were contaminated, resulting in the evacuation of roughly 200,000 people. The accident raised concerns about the safety of the Soviet nuclear power industry, slowing its expansion for a number of years, while forcing the Soviet government to become less secretive.   Ã‚  Ã‚  Ã‚  Ã‚  The Chernobyl’ Nuclear Power Plant was one of the largest in the USSR. It was located just outside of the town of Pripyat’, about 18 km northwest of the town of Chernobyl’. The plant was only 16 km from the border between the Ukrainian and Belorussian republics and roughly 110 km north of Kiev, the capital and largest city of Ukraine. Construction of the plant began in the 1970s, with reactor No. 1 commissioned in 1977, followed by No. 2 (1978), No. 3 (1981), and No. 4 (1983). Each reactor had an electricity-generating capacity of 1,000 megawatts, and the four together produced about 10 percent of Ukraine's electricity at the time of the accident. Two more reactors (No. 5 and No. 6, also capable of producing 1,000 megawatts each) were under construction at the time of the accident. On the morning of April 26, 1986, reactor No. 4 was operating at very low capacity (6 to 7 percent) during a planned shutdown. Plant personnel intended to monitor t he performance of turbine generators, which supplied electric power for the plant’s own operation, during a changeover from standard to a backup source of power. The reactor’s design made it unstable at low power, and the operators were careless about safety precautions during the test. After a sudden power surge, two explosions destroyed the reactor core and blasted a large hole in the roof of the reactor building. Radioactive debris moved up through this hole to heights of 1 km.   Ã‚  Ã‚  Ã‚  Ã‚  An estimated 100 to 150 million curies of radiation (primarily radioactive isotopes of iodine and cesium) escaped into the atmosphere before cleanup crews were able to bring the fires under control and stabilize the situation two weeks later. Prevailing winds carried the radioactivity northwest from the plant across Belorussia and into Poland and Sweden, where heightened radiation levels detected on April 28 first brought the accident to the world's attention.

Essay example --

It was one of the greatest battles in Greek history, the battle of Achilles with Hector (Homer. Iliad. 22) and Cycnus (Ovid. Metamorphoses. 14); these two different versions of the Trojan War had both similarities and differences. As we can notice from these two books, there are similarities of character in Homer’s version of Achilles and Ovid’s version Achilles. Furthermore, the similarity of both Trojan heroes having the same enemy in both versions of The Trojan War. On the other hand, the difference between these two battles of Achilles is the character and how both Trojan heroes performed during the battle with Achilles. In addition, the main reason initiates battle of Achilles is different when he fights with Hector and Cycnus; additionally, how Achilles treats their corpse after he kills them, were not the same in both battles. Furthermore, the setting and timing of the battle between Achilles and the two Trojan heroes are distinct from one to another. According to Homer, Hector was the greatest and most famous mortal heroes in the history of Troy, who has protected Troy from many wars and have been treated as the guardian of his father, Priam kingdom. On the other hand, in Ovid version of The Trojan War, there are two great Trojan warriors, Hector and Cycnus, son of Poseidon, the latter is invulnerable warrior and have killed 1000 Greeks troop at the Trojan beach easily when the Greeks first landed on the beach. The character of Achilles, son of Peleus, in both battles has some similarities which are the violent, arrogant and uncontrollable like a beast. Achilles trusted his skill to fight and shows his arrogant character can be found in Iliad, â€Å"Achilles shook his head at his soldiers: He would not allow anyone to shoot A... ... year of the war. In general, the battle of Achilles with Hector and Cycnus had some similarities and differences. Both of the Trojan heroes are loyal to their country and both are Troy greatest warriors. Other than that, both versions of Achilles poses the arrogant and beast characteristic. However, the characters and attitudes of Hector and Cycnus in the battle with Achilles are completely different, where Hector fears and hesitate to battle with Achilles while Cycnus confidently faces the battle with Achilles. In addition, the main reason of battles is different which lead to different treatment of Achilles to their corpse, where Hector corpse was badly treated by Achilles rage for the revenge of Patroclus death. Last but not least, the setting of both battles Trojan heroes is completely different, even-thought they were fighting with the same enemy, Achilles.

Compare and Contrast: Eveline vs Dave

Osvaldo Miranda Oren, Gail 9-16-2012 Enc1102 Eveline vs. Dave Writers of modern stories are interested in portraying life. Often, in their stories, we get ideas and find the chance to see, examine, and question ourselves. For example, in James Joyce’s â€Å"Eveline,† we observe how fear of the unknown affects a young woman’s future; In Richard Wright’s â€Å"The Man Who was Almost a Man,† we see how a young boy’s inability to accept moral responsibilities impacts his life, too. â€Å"How would we handle their challenges? Who is the stronger individual? The answer lies within. Both characters showed strength at some point of the stories. Dave showed strength and courage for going out to buy a gun. At the same time it was immature and a bad decision for someone who is not ready to be a man. Eveline’s strength showed throughout the whole story. She was brave, hardworking, and loyal. After the passing of her mother Eveline became the woma n of the household and started taking care of her family and bringing home money.It’s pretty obvious that Eveline has the more strength when comparing her to Dave. All of Eveline’s decisions were because of her loyalty to her family. At the end of the day she stepped up and stayed in Ireland to take care of her family. Dave is in a rush to grow up and not letting things come in time. He is impatient and his immaturity shows because of this. Dave’s decision making is not very good, he convinces his mom to buy a gun so no one would think of him as a boy anymore.This decision backfires on him when he accidently shoots a sheep while testing out the gun for the first time. The sheep’s owner is Dave’s boss and she charges him for the death of the sheep with monthly payments. Dave immaturity kicks in again and decides to flee because he can’t accept the responsibility and consequences for his actions. If you think about it Dave’s living situ ation wasn’t as challenged as Eveline’s. She had to deal with real life problems while Dave was dealing with personal options and caring what other people thought of him.Eveline’s tough situation and smart decision making shows why she has more strength than Dave. In conclusion, Dave shows he has strength in the wrong ways, and he is irresponsible and immature. Eveline on the other hand has real life problems that anyone would have problems dealing with. It is inspiring to see how much strength and loyalty Eveline has towards her family. There is no doubt in my mind that Eveline is the character with the most strength.

Metes, Bounds Meanders - Platting the Land of Your Ancestors

Metes, Bounds Meanders - Platting the Land of Your Ancestors In the original thirteen colonies, plus Hawaii, Kentucky, Maine, Texas, Tennessee, Vermont, West Virginia, and parts of Ohio (the state land states), land boundaries are identified according to the indiscriminate survey system, more commonly referred to as metes and bounds. The metes and bounds land survey system relies on several different items to convey a property description: General Location - details on the propertys location, possibly including the state, county, and township; nearby waterways; and acreage.Survey Lines - describes the boundaries of the property using direction and distance.Boundary Descriptions - details on natural features found along the property boundaries, such as creeks and trees.Neighbors - names of neighboring property owners whose land shares a line or adjoins at a corner. How the Land Was Surveyed Surveyors in early America used only a few simple tools to measure direction, distance, and acreage of a parcel of land. Distance was usually measured with an instrument called a Gunters chain, measuring four poles (sixty-six feet) in length and consisting of 100 linked pieces of iron or steel. Indicators hung at certain points to mark important subdivisions. Most metes and bounds land descriptions describe distance in terms of these chains, or in measurements of poles, rods, or perches - interchangeable units of measurement equaling 16 1/2 feet, or 25 links on a Gunters chain. A number of different instruments were used to determine the direction of survey lines, the most common being the magnetic compass. Since compasses point to magnetic north, rather than true north, surveyors may have corrected their surveys by a particular declination value. This value is important when trying to fit an old plot on a modern map, as the location of magnetic north is constantly drifting. There are two primary types of systems used by surveyors to describe direction: Compass Degrees - the standard system used in most locations, compass degree headings specify a compass point (North, South, East or West), followed by a number of degrees, and then another compass point.Example: N42W, or 42 degrees west of north Compass Points - Found in some early colonial land descriptions, compass points, or compass card directions, refer to the 32-point compass card. This system of describing direction was, by its very nature, imprecise and, luckily, was also rarely used.Example: WNW 1/4 N, or the compass point midway between west and northwest by one quarter point north Acreage was usually determined with the aid of tables and charts and, due to meanders and strangely shaped, non-rectangular parcels of land, could often be fairly inaccurate. When a boundary ran along a creek, stream, or river, the survey often described this with the word meander. This usually meant that the surveyor did not attempt to pinpoint all of the changes in directions of the creek, instead noting that the property line followed the meanders of the waterway. A meander can also be used to describe any line noted in a survey which does not provide both direction and distance - even if there is not any water involved. Deciphering the Lingo I still remember the first time that I saw a metes and bounds land description in a deed - it looked like a lot of confusing gibberish. Once you learn the lingo, however, youll find that metes and bounds surveys make a lot more sense than they appear to at first glance. ...330 acres of land lying in Boufort County and on the East side of Coneto Creek. Beginning at a white oak in Michael Kings line: then by sd [said] line S[outh] 30 d[egrees] E[ast] 50po[les] to a pine then E 320 poles to a pine then N 220 poles to a pine then by Crisps line west 80 poles to a pine then down the creek to the first station.... Once you look closer at the land description, youll notice that it follows a fairly basic pattern of alternating calls, consisting of corners and lines. Corners use physical or geographical markers (e.g. white pine) or the name of an adjoining land owner (e.g. Michael King) to describe an exact location on the parcel of land. Lines are then used to describe the distance and direction to the next corner (e.g. South 30 degrees East 50 poles), and may also be described using physical markers such as a stream (e.g. down the creek), or the names of adjoining property owners. A metes and bounds land description always begins with a corner (e.g. Beginning at a white oak in Michael Kings line) and then alternates lines and corners until returning to the starting point (e.g. to the first station). Next Page Land Platting Made Easy One of the best ways to study local history in general, and your family in particular, is to create a map of your ancestors land(s) and its relationship to the surrounding community. Making a plat from a land description may sound complicated, but it is actually very simple once you learn how. Land Platting Supplies Tools To plat a tract of land in metes and bounds bearings i.e. draw the land on paper the way the surveyor originally did you need only a few simple tools: Protractor or Surveyors Compass - Remember that half-circle protractor that you used in high school trigonometry? This basic tool, found in most office and school supply stores, is an easy-to-obtain tool for land platting on the fly. If you plan to do a lot of land platting, then you may want to purchase a round surveyors compass (also known as a land measure compass), available from specialty supply stores.Ruler - Again, easily found in office supply stores. The only requirement is that it is marked in millimeters.​Graph Paper - Used only to keep your compass aligned perfectly north-south, the size and type of graph paper is really not important. Patricia Law Hatcher, an expert in land platting, recommends engineering paper, with four to five equally-weighted lines per inch.Pencil Eraser - Wood pencil, or mechanical pencil - its your choice. Just make sure its sharp!Calculator - Doesnt need to be fancy. Just simple multiplication and division. Pencil and paper will work too - just takes longer. As you can see, the basic tools required for land platting can all be found at a local office supply store or discount mass merchandiser. So, next time youre on the road and run across a new deed, you dont have to wait until you get home to plat it out on paper. Land Platting Step-by-Step Transcribe or make a copy of the deed, including the full legal land description.Highlight the calls - lines and corners. Land platting experts Patricia Law Hatcher and Mary McCampbell Bell suggest to their students that they underline the lines (including distance, direction, and adjoining owners), circle the corners (including neighbors), and use a wavy line for meanders.Create a chart or list of the calls for easy reference as you play, including only the pertinent information or facts. Check off each line or corner on the photocopy as you work to help prevent errors.If you plan to overlay your plat onto a modern day USGS quadrangle map, then convert all distances to USGS scale and include them on your chart. If your deed description uses poles, rods, or perches, then divide each distance by 4.8 for an easy conversion.Draw a solid dot on your graph paper to indicate your starting point. Next to it write down the description of the corner (e.g. Beginning at a white oak in Michael K ings line). This will help you remember that this was your starting point, as well as including the markers which will help you possibly match it up with adjoining plats. Place the center of your protractor on top of the dot, making sure that it is aligned with the grid on your graph paper and that north is on top. If youre using a semi-circular protractor, orient it so that the circular side faces toward the east or west direction of the call (e.g. for the line S32E - align your protractor with the circular side facing east).

The Influence of Supply and Demand on Inflation

The Influence of Supply and Demand on Inflation Inflation is an increase in the price of a basket of goods and services that is representative of the economy as a whole. In other words, inflation is an upward movement in the average level of prices, as defined in Economics by Parkin and Bade. Its opposite is deflation, a downward movement in the average level of prices. The boundary between inflation and deflation is price stability. The Link Between Inflation and Money An old adage holds that inflation is too many dollars chasing too few goods. Because inflation is a rise in the general level of prices, it is intrinsically linked to  money.   To understand how inflation works, imagine a world that only has two  commodities: oranges picked from orange trees and paper money printed by the government. In a drought year when oranges are scarce, one would expect to see the price of oranges rise, because quite a few dollars would be chasing very few oranges. Conversely, if there was a record orange crop, one would expect to see the price of oranges fall because orange sellers would need to reduce their prices in order to clear their inventory. These scenarios represent inflation and deflation, respectively. However, in the real world, inflation and deflation are changes in the average price of all goods and services, not just one. Altering the Money Supply Inflation and deflation can also result when the amount of  money in the system  changes. If the government decides to print a lot of money, then dollars will become plentiful relative to oranges, as in the earlier drought example.   Thus, inflation is caused by the number of dollars rising relative to the number of oranges (goods and services). Similarly, deflation is caused by the number of dollars falling relative to the number of ​oranges (goods and services). Therefore, inflation is caused by a combination of four factors: the supply of money goes up, the supply of other goods goes down, demand for money goes down and demand for other goods goes up. These four factors are thus linked to the basics of supply and demand. Different Types of Inflation Now that we have covered the basics of inflation, it is important to note that there are many types of inflation. These types of inflation are differentiated from each other by the cause that drives the price increase. To give you a taste, lets briefly go over ​cost-push inflation and demand-pull inflation.   Cost-push inflation is a result of a decrease in aggregate supply. Aggregate supply is the supply of goods, and a decrease in aggregate supply is mainly caused by an increase in wage rate or an increase in the price of raw materials. Essentially,  prices for consumers are pushed up  by increases in the cost of production. Demand-pull inflation occurs when there is an increase in aggregate demand. Simply put, consider how when demand increases, prices are pulled higher.

Siege of Boston in the American Revolution

Siege of Boston in the American Revolution The Siege of Boston occurred during the American Revolution and began April 19, 1775 and lasted until March 17, 1776. Commencing after the opening battles at  Lexington Concord,  the Siege of Boston saw the growing American army block the land approaches to Boston. During the course of the siege, the two sides clashed at the bloody Battle of Bunker Hill in June 1775. The stalemate around the city also saw the arrival of two commanders who would play a central role in the conflict over the next three years:  General George Washington  and  Major General William Howe. As the fall and winter progressed, neither side proved able to gain an advantage. This changed in early 1776 when artillery captured at Fort Ticonderoga arrived in the American lines. Mounted on Dorchester Heights, the guns compelled Howe to abandon the city. Background In the wake of the Battles of Lexington Concord on April 19, 1775, American colonial forces continued to attack British troops as they attempted to withdraw back to Boston. Though aided by reinforcements led by Brigadier General Hugh Percy, the column continued to take casualties with particularly intense fighting occurring around Menotomy and Cambridge.  Finally reaching the safety of Charlestown late in the afternoon, the British were able to gain a respite. While the British consolidated their position and recovered from the days fighting, militia units from across New England began arriving on the outskirts of Boston. Armies Commanders Americans General George WashingtonMajor General Artemas Wardup to 16,000 men British Lieutenant General Thomas GageMajor General William Howeup to 11,000 men Under Siege By morning, around 15,000 American militiamen were in place outside of the city. Initially guided by Brigadier General William Heath of the Massachusetts militia, he passed command to General Artemas Ward late on the 20th. As the American army was effectively a collection of militias, Wards control was nominal, but he succeeded in establishing a loose siege line running from Chelsea around the city to Roxbury. Emphasis was placed on blocking Boston and Charlestown Necks. Across the lines, the British commander, Lieutenant General Thomas Gage, elected not impose martial law and instead worked with the citys leaders to have private weapons surrendered in exchange for allowing those residents who desired to leave Boston to depart. The Noose Tightens Over the next several days, Wards forces were augmented by new arrivals from Connecticut, Rhode Island, and New Hampshire. With these troops came permission from the provisional governments of New Hampshire and Connecticut for Ward to assume command over their men. In Boston, Gage was surprised by the size and perseverance of the American forces and stated, In all their wars against the French they never showed such conduct, attention, and perseverance as they do now. In response, he began fortifying parts of the city against attack. Consolidating his forces in the city proper, Gage withdrew his men from Charlestown and erected defenses across Boston Neck. Traffic in and out of the city was briefly restricted before both sides came to an informal agreement allowing civilians to pass as long as they were unarmed. Though deprived of access to the surrounding countryside, the harbor remained open and ships of the Royal Navy, under Vice Admiral Samuel Graves, were able to supply the city. Though Graves efforts were effective, attacks by American privateers led prices for food and other necessities to rise dramatically. Lacking artillery to break the stalemate, the Massachusetts Provincial Congress dispatched Colonel Benedict Arnold to seize the guns at Fort Ticonderoga. Joining with Colonel Ethan Allens Green Mountain Boys, Arnold captured the fort on May 10. Later that month and into early June, American and British forces skirmished as Gages men attempted to capture hay and livestock from the outer islands of Boston Harbor (Map). Battle of Bunker Hill On May 25, HMS Cerberus arrived at Boston carrying Major Generals William Howe, Henry Clinton, and John Burgoyne. As the garrison had been reinforced to around 6,000 men, the new arrivals advocated for breaking out of the city and seizing Bunker Hill, above Charlestown, and Dorchester Heights south of the city. The British commanders intended to implement their plan on June 18. Learning of the British plans on June 15, the Americans quickly moved to occupy both locations. To the north, Colonel William Prescott and 1,200 men marched onto the Charlestown Peninsula on the evening of June 16.  After some debate among his subordinates, Prescott directed that a redoubt be constructed on Breeds Hill rather than Bunker Hill as originally intended. Work commenced and continued through the night with Prescott also ordering a breastwork to be built extending down the hill to the northeast. Spotting the Americans works the next morning, British warships opened fire with little effect. In Boston, Gage met with his commanders to discuss options. After taking six hours to organize an assault force, Howe led British forces over to Charlestown and attacked on the afternoon of June 17. Repelling two large British assaults, Prescotts men stood firm and were only forced to retreat when they ran out of ammunition. In the fighting, Howes troops suffered over 1,000 casualties while the Americans sustained around 450. The high cost of victory at the Battle of Bunker Hill would influence British command decisions for the remainder of the campaign. Having taken the heights, the British began work to fortify Charlestown Neck to prevent another American incursion. Building an Army While events were unfolding in Boston, the Continental Congress in Philadelphia created the Continental Army on June 14 and appointed George Washington as commander-in-chief the following day. Riding north to take command, Washington arrived outside Boston on July 3. Establishing his headquarters in Cambridge, he began molding the masses of colonial troops into an army. Creating badges of rank and uniform codes, Washington also began creating a logistical network to support his men. In an attempt to bring structure to the army, he divided it into three wings each led by a major general. The left wing, led by Major General Charles Lee was tasked with guarding the exits from Charlestown, while Major General Israel Putnams center wing was established near Cambridge. The right wing at Roxbury, led by Major General Artemas Ward, was the largest and was to cover Boston Neck as well as Dorchester Heights to the east. Through the summer, Washington worked to expand and reinforce the American lines. He was supported by the arrival of riflemen from Pennsylvania, Maryland, and Virginia. Possessing accurate, long range weapons, these sharpshooters were employed in harassing the British lines. Next Steps On the night of August 30, British forces launched a raid against Roxbury, while American troops successfully destroyed the lighthouse on Lighthouse Island. Learning in September that the British did not intend to attack until reinforced, Washington dispatched 1,100 men under Arnold to conduct an invasion of Canada. He also began planning for an amphibious assault against the city as he feared his army would break up with the arrival of winter. After discussions with his senior commanders, Washington agreed to postpone the attack. As the stalemate pressed on, the British continued local raiding for food and stores. In November, Washington was presented a plan by Henry Knox for transporting Ticonderogas guns to Boston. Impressed, he appointed Knox a colonel and sent him to the fort. On November 29, an armed American ship succeeded in capturing the British brigantine Nancy outside of Boston Harbor. Loaded with munitions, it provided Washington with much needed gunpowder and arms. In Boston, the situation for the British changed in October when Gage was relieved in favor of Howe. Though reinforced to around 11,000 men, he was chronically short on supplies. The Siege Ends As winter set in, Washingtons fears began to come true as his army was reduced to around 9,000 through desertions and expiring enlistments. His situation improved on January 26, 1776 when Knox arrived in Cambridge with 59 guns from Ticonderoga. Approaching his commanders in February, Washington proposed an attack on the city by moving over the frozen Back Bay, but was instead convinced to wait. Instead, he formulated a plan to drive the British from the city by emplacing guns on Dorchester Heights. Assigning several of Knoxs guns to Cambridge and Roxbury, Washington began a diversionary bombardment of the British lines on the night of March 2. On the night of March 4/5, American troops moved guns to Dorchester Heights from which they could strike the city and the British ships in the harbor. Seeing the American fortifications on the heights in the morning, Howe initially made plans for assaulting the position. This was prevented by a snowstorm late in the day. Unable to attack, Howe reconsidered his plan and elected to withdraw rather than have a repeat of Bunker Hill. The British Depart On March 8, Washington received word that the British intended to evacuate and would not burn the city if allowed to leave unmolested. Though he did not formally respond, Washington agreed to the terms and British began embarking along with numerous Boston Loyalists. On March 17, the British departed for Halifax, Nova Scotia and American forces entered the city. Having been taken after an eleven-month siege, Boston remained in American hands for the remainder of the war.

Three Main Components - Essay Example It is therefore important to understand the functions, structure and how the criminal American criminal justice system works. The criminal justice system three main components charged with different roles that ensure justice and order. These are the police, courts and corrections working synergistically to serve the intended purpose. Police component of the criminal justice system is composed of state and special service police. State police arm is charged with the roles of patrolling highways, enforcing law & order in rural locations and assisting in the investigative function of local police. Special service police ensure law enforcement in institutions such as the transport sector, school districts, housing etc. The court system in the United States is divided into two i.e. state and federal courts. There is in that states have their own independent court systems. Three levels exist in most state court systems which are the court with limited jurisdiction, courts with general jurisdiction as well as appellate courts. Courts majorly are charged with guarding the constitution in addition to assurance of l aw and order. Corrections are those functions of the criminal justice system aimed at rehabilitating offenders. Programs include paroles, probation, and prisons. Prisons are also of two types; detention and correctional facilities. The court system is the most effective component of the criminal justice system when it comes to discharge its duties. This because it involves adversaries; defense attorney and prosecutor work as opponents while defending their clients’ rights. Victims and the state are represented by the prosecutor while accused persons are represented by their attorneys. The courts are at all times mindful of the individual rights of both accused persons and victims as they are guardians of the constitution. They are obliged to follow â€Å"Due process right† as envisaged in the
