Lewis and Clark The story essays

Lewis and Clark The story essays The Lewis and Clark expedition across the present day United States began May 14, 1804. With the approval of President Jefferson and the U.S. Congress, Lewis and Clark gathered an exploration party of about four dozen men. These men headed off to discover Western America. On September 1, 1805, they arrived at the Bitterroot Mountains, near present day Idaho. This began a nightmare that would not end until they reached modern-day Weippe. September 1, 1805, the explorers set out traveling west, heading into rough, seldom traveled, mountainous country. They stopped at todays North Fork of the Salmon River, known as Fish Creek to Lewis and Clark, where they caught five fish, and were able to kill a deer (MacGregor 125). Some of the mens feet and horses hooves were injured due to the rough, rocky terrain. The next day, they were entering mountains far more difficult to pass than any American had ever attempted (Ambros 284). Clark describes the route: Throu thickets in which we were obliged to cut a road, over rocky hillsides where horses were in perpetual danger of slipping to their certain distruction and up and down steep hills... (De Voto 232). Traveling along the steep hills, several horses fell. One was crippled, and two gave out. Patrick Gass described the trip that day as, ...the worst road (If road it can be called) that was ever traveled (MacGregor 125). To make conditions even worse, it rained that afternoon, which made the trail even more treacherous. The party was only able to travel five miles that day. On September 3, snow fell and the teams last thermometer broke. Several more horsed slipped and injured themselves. Later that day, the snow turned into sleet. The expedition family consumed the last of their salt pork and fish and began their descent into the Bitterroot Valley. That night, was the coldest yet. The next day, the party wen...

Biography of Fences Playwright August Wilson

Biography of Fences Playwright August Wilson Award-winning playwright August Wilson had no shortage of fans during his life, but his writing enjoyed renewed interest after a film adaptation of his play â€Å"Fences† opened in theaters on Christmas Day 2016. The critically acclaimed film not only earned kudos for stars Viola Davis and Denzel Washington, who also directed, but exposed new audiences to Wilson’s work as well. In each of his plays, Wilson shined a spotlight on the lives of the working class African Americans overlooked in society. With this biography, learn how Wilson’s upbringing influenced his major works. Early Years August Wilson was born April 27, 1945, in Pittsburgh’s Hill District, a poor black neighborhood. At birth, he bore his baker father’s name, Frederick August Kittel. His father was a German immigrant, known for his drinking and temper, and his mother, Daisy Wilson, was African American. She taught her son to stand up to injustice. His parents divorced, however, and the playwright would later change his surname to his mother’s, for she was his primary caregiver. His father did not have a consistent role in his life and died in 1965. Wilson experienced fierce racism attending a succession of nearly all-white schools, and the alienation he felt as a result eventually led him to drop out of high school at 15. Leaving school did not mean Wilson had given up on his education. He decided to educate himself by regularly visiting his local library and voraciously reading the offerings there. A self-taught education proved fruitful for Wilson, who would earn a high school diploma due to his efforts. Alternatively, he learned important life lessons by listening to the stories of the African Americans, mostly retirees and blue-collar workers, in the Hill District. A Writer Gets His Start By 20, Wilson decided that he would be a poet, but three years later he developed an interest in theater. In 1968, he and his friend Rob Penny started the Black Horizons on the Hill Theater. Lacking a place to perform, the theater company staged its productions at elementary schools and sold tickets for just 50 cents by herding in passersby outside just before the shows started. Wilson’s interest in theater waned, and it wasn’t until he moved to St. Paul, Minn., in 1978 and began adapting Native American folktales into childrens plays that he renewed his interest in the craft. In his new city, he began to recall his old life in the Hill District by chronicling the experiences of the residents there in a play, which developed into â€Å"Jitney.† But Wilson’s first play staged professionally was â€Å"Black Bart and the Sacred Hills,† which he wrote by piecing together several of his old poems.    Lloyd Richards, the first black Broadway director and dean of the Yale School of Drama, helped Wilson refine his plays and directed six of them. Richards was artistic director of Yale Repertory Theater and head of the Eugene ONeill Playwrights Conference in Connecticut to which Wilson would submit the work that made him a star, â€Å"Ma Rainey’s Black Bottom.† Richards gave Wilson guidance on the play and it opened at the Yale Repertory Theatre in 1984. The New York Times described the play as â€Å"a searing inside account of what white racism does to its victims.† Set in 1927, the play details the rocky relationship between a blues singer and a trumpet player. In 1984, â€Å"Fences† premiered. It takes place in the 1950s and chronicles the tensions between a former Negro leagues baseball player working as a garbage man and the son who also dreams of an athletic career. For that play, Wilson received the Tony Award and the Pulitzer Prize. The playwright followed up â€Å"Fences† with â€Å"Joe Turners Come and Gone,† which takes place in a boardinghouse in 1911. Among Wilson’s other key works is The Piano Lesson, the story of siblings fighting over a family piano in 1936. He received his second Pulitzer for that 1990 play. Wilson also wrote Two Trains Running, Seven Guitars, King Hedley II, Gem of the Ocean and Radio Golf, his last play. Most of his plays had Broadway debuts and many were commercial successes. Fences, for example, boasted earnings of $11 million in one year, a record at that time for a nonmusical Broadway production. A number of celebrities starred in his works. Whoopi Goldberg acted in a revival of Ma Raineys Black Bottom in 2003, while Charles S. Dutton starred in both the original and the revival. Other famous actors who’ve appeared in Wilson productions include S. Epatha Merkerson, Angela Bassett, Phylicia Rashad, Courtney B. Vance, Laurence Fishburne and Viola Davis. In total, Wilson received seven New York Drama Critics Circle awards for his plays. Art for Social Change Each of Wilson’s works describes the struggles of the black underclass, be they sanitation workers, domestics, drivers or criminals. Through his dramas, which span different decades of the 20th century, the voiceless have a voice. The plays expose the personal turmoil the marginalized endure because their humanity all too often goes unrecognized by their employers, by strangers, by family members and America overall. While his plays tell the stories of an impoverished black community, there’s a universal appeal to them as well. One can relate to Wilson’s characters in the same way one can relate to the protagonists of Arthur Miller’s works. But Wilson’s plays stand out for their emotional gravitas and lyricism. The playwright didn’t want to gloss over the legacy of slavery and Jim Crow and their impact on his character’s lives. He believed that art was political but didn’t consider  his own plays to be explicitly political. I think my plays offer (white Americans) a different way to look at black Americans, he told The Paris Review  in 1999. For instance, in ‘Fences they see a garbage man, a person they dont really look at, although they see a garbage man every day. By looking at Troys life, white people find out that the content of this black garbage mans life is affected by the same things - love, honor, beauty, betrayal, duty. Recognizing that these things are as much part of his life as theirs can affect how they think about and deal with black people in their lives.† Illness and Death Wilson died of liver cancer on Oct. 2, 2005, at the age of 60 in a Seattle hospital. He had not announced that he was suffering from the disease until a month before his death. His third wife, costume designer Constanza Romero, three daughters (one with Romero and two with his first wife) and several siblings survived him. After he succumbed to cancer, the playwright continued to receive honors. The Virginia Theater on Broadway announced that it would bear Wilson’s name. Its new marquee went up two weeks after his death.

The Era of Franklin Delano Roosevelt, 1933-1945 Essay

The Era of Franklin Delano Roosevelt, 1933-1945 - Essay Example He believed it was the role of the government to offer a solution to these problems. This essay will focus on how Franklin Delano Roosevelt consistent set of plans for ending the Great Depression throughout the first part of his Presidency. Franklin felt that people working in most public offices lacked social values and focused more on money in his opinion, the lack of ethics had greatly contributed to corruption hence the depression. Moreover, he felt that the financial systems required to works harder towards resolving the crisis instead of dwelling in the fear emanating from the crisis (Polenberg 39-40). He believed that people working in financial systems especially the exchange market had focused more on using their mandate for personal financial gains contributing to the depression. He thus insisted on the need for transparency and accountability by the public officers (Polenberg 43) Franklin believed that recovery and reform were closely interconnected. He therefore suggested social objectives of the new deal that aimed at offering more jobs o the Americans. Moreover, he believed it was important to enhance security and enable Americans have access to decent homes. To be able to achieve the above plans, Franklin suggested a program that aimed at providing approximately 3.5 million jobs. His other projects included rural electrification, reforestation, as well as slum clearance (Polenberg 54-56). Another plan that Franklin proposed was the need for equality. He believed that some private companies were exploiting common Americans due to their urge to increase their profits. Therefore, he planned to enhance equality and ensure that all Americans were able to enjoy security and enjoy reasonable leisure. Moreover, Franklin planned to ensure that the national resources were utilized appropriately to benefit all, people were protected from hazards of life especially those associated with the depression, and people would eventually enjoy living in decent homes irrespective of the crisis. The above plans remained important to Franklin throughout his reign (Polenberg 39-42). To ensure that the natural resources were used appropriately to proposed the need for appropriate use of land and water resources. To ensure that all Americans were secured from life hazards, Roosevelt believed that it was important to create employment opportunities and insurance services. In his opinion, the old, handicapped, children, and pregnant mother required insurance benefits (Polenberg 48-50) To ensure that Americans enjoyed living in better homes, Franklin believed it was important to empower the unemployed by giving them jobs. This could be achieved through enactment of policies that would create employment opportunities. Franklin argued that the large government debt had resulted due to increased dependence of many Americans on the relief rolls. This had resulted in burdening of the federal government. He proposed that it was appropriate to offer jobs to t he unemployed to prevent them from relying on federal aid. He believed that the only group of people that required federal relief was those who could not manage to toil for various reasons. However, the larger percentage of people depending on the federal relief funds was employable. However, the group had been rendered jobless by the circumstances surrounding the depression. He thus believed that it

Leadership Impact Essay Example for Free

Leadership Impact Essay This research paper is written on the Leadership styles and the impact they have on the workforce. My information is based on my direct observation while being employed in the U. S. Air Force. My paper will analyze Leadership styles by using two concepts from Robbins and Judge (2009). The two concepts I have chosen are Leader Behaviors (p. 397) and Vision Statement (p. 415). Leadership Behaviors Being in the military for the past nine years has giving me an opportunity to see many different leadership behaviors. Four leadership behaviors Robbins and Judge (2009) defined are directive, supportive, participative, and achievement-oriented leaders (p. 397). The directive leader defines what is expected of the worker and schedules the work (p. 397). I feel that most people start off in with this leadership behavior until they grow as a leader. The supportive leader is concerned with the needs of their followers and interacts with them (p. 397). I have worked with many leaders that have used this behavior and it make them a popular leader, but can make it hard for them to get work done by some of their followers. I have seen were the workers take advantage of a leader because they feel more like a friend and not a boss. The participative leader takes the input of the follower and uses them before making a decision (p. 397). The Air Force leadership does use this behavior by using a yearly climate survey. The last leader behavior is the achievement-oriented leader. I feel that for the most part the behavior is the hardest to work for. This leadership style does not show much concern for the followers and does not take in their input. The leader is goal orientated and expects the followers to perform at their best to meet the goals (p. 97). Vision Statement A vision statement is a tool that leadership can use to tell why the organization exists (Kaplan Norton, 2008). Most military units have a vision statement to motivate its members. My unit’s statement is Safety first, By the book, Then on time. Our vision statement put the safety of the workers first and the sets the attitude of how the work is to be done. Robbins and Judge (2009) state that a vision should be value centered (p. 415) and all the military units I have worked for have had a vision statement that puts it people first. I feel it can make it easier to work for someone if they value you. Conclusion Leaders may use any of the behavior styles talk about in the paper. Charismatic leaders will try to set a goal and good work environment for their workers (Fischer). The leaders of an organization will have to ensure they use the right behavior to motivate its workers. In Psalm 28:11 David asks to be taught the Lords way and be lead in a straight path. I think this is how a lot of employees feel and it is the job of the leaders to ensure they know what path the organization is going.

COMPUTER SECURITY ISSUES :: Essays Papers

COMPUTER SECURITY ISSUES Computer Security Issues Facing Alsager Ltd. In upgrading the Alsager Ltd IT facilities, despite numerous advantages that the new systems brings one has to be made aware of the possible threats posing. Virus can effect the system. They are pieces of codes created by hacker to create a nuisances and to another extreme corrupt valuable data. Examples of these can be animated icons flying pass the computer screen and to another extreme can be programmes designed to delete the hard drive. The Computer Virus can be caught through a number of ways. The most highly publicised way, is through the Internet, other ways are through removable storage media, such as floppy disks and zip drives. They can also be caught through computer networks, where a third party from another machine in the network introduces the virus (accidental or otherwise) which then spread throughout the network. The most unlikely way of virus contaminating the system is through malicious employees creating them on the system but this will be discussed later on. There are a number of precautions that can be taken to help prevent this. By simply making employees not to use mobile storage media unless they know where it has been, making them aware that pirated media , shareware/freeware programmes may be potentially dangerous. A talk and leaflet distribution to employees could be useful. If the Alsager decides to connect to the Internet, this would be another potential source for virus and such like. A firewall could be placed on the system to help prevent infection. A more immediate way of preventing virus is to subscribe to a antivirus programmes, although this will not give you 100% percent protection it will help prevent the majority of known virus. An important note to this point, is the importance of getting regular virus updates from the software manufacturer. With the introduction of the IT facilities, the amount of room information takes up is drastically reduced from a whole filing cabinet to a small hard drive. Information can be easily copied and since the advent of the Internet, information does not even have to be on a psychical media to leave the building. This therefore makes it much more easier to copy and take out valuable information. All the companies details, there accounts and their customers account are prone to the risk. A single person can take out all the information on a zip disk or even a floppy disk depending on the size of the file.

Advantages and Disadvantages in Sport Technology Essay

Technology in sports is constantly changing in today’s era. This change is making a big impact, whether the technology is a disadvantage to the sport and slows down the speed of the game or uses the technology to an advantage and speeds the game up to help make accurate calls. People are always looking for the technology to be able to get ahead of other opponents. The use of technology has crept into the athletes’ games. Technology may not be a drug but a large amount of people use it. It is hard to say whether the use of technology is more of an advantage or disadvantage. One of the main reasons technology compromise a sport experience is that people are watching the games at home instead of watching the games that are played live. Some people would rather stay at home than spend the money to go to the game. With the games being shown on television that means fewer supporters in attendance. Fewer supporters mean less money for the teams in terms of income and profits. The enhance experience of technology has made it easy for teams to know and learn about the opposite teams. Some people believe that it was necessary for technology. The technology used in the National Football League has come a long way. For example, the â€Å"1st and Ten† graphics system has enhanced the football game to another level. The purpose of the â€Å"1st and Ten† line is displayed in a yellow color that shows the yards needed to make a first down. This system displays live to the television viewers only, it does not physically show on the field of play. The example I chose that enhances or compromises the sport with technology is in football with the use of instant replay, during a National Football League game. Everyone knows that the umpire or the referee is not always right. With football, the coaches are allowed to throw out a flag of their own and challenge the call on the field. The challenges are made toward the disputed call made by the on-field referee and they pass it on to the television official. If the official did not get the call right and the instant replay shows it as such, the team retains the time out and wins the call. If the instant replay shows what the official called, the team loses the call and a time out. The monitors are positioned in several spots on the field so the camera can capture the play at different angles whether it is in slow motion or game speed. The technology of instant replay sounds good to the viewers at the game or at home, but there is a lot of pressure for the official to get the call right. The instant replay can distract the players from the game or make them lost momentum if the process takes too long. Some challenges are considered thoughtless or in vain as a distraction. There are problems with the instant replay system that needs to be leveled out, but the system allows the game to get a stage future in technology in sport. Possible guidelines for the use of technology in spot are first of all the instant replay. The officials in the booth should be able to make the decision about the disputed play to save time and keep the game going smoothly. As far as clothes goes, the Haptic Sports Garment is a clothing line that should not be used during game time. The garment helps the athlete to uphold the most advantageous speed. In relevance to the Internet, the applications Venuing and Twackle are used by fans where they get involved with the players and teams to much. Next is the use of the DVD. The player’s highlights are being displayed to the scouts to use them to their advantage. A scout should not be allowed to get a highlighted DVD of a player unless they have the player’s permission. Finally, the swimming designer Speedo’s that bonds seams ultrasonically and reduce drags with the fabric made of water-repellent should not be used if all the swimmers are not using them during the race.

Basic Chemistry for investigating living things

Which test tube represents the control? The one with water. C. Why? When protein molecules are present, Beirut Reagent reacts with the protein to form a purple color. Tube number one is the control tube because it is distilled water and has no protein; the tube has no color. C. Which test tube contained the most test substance? Amylase D. Other than the control, which test tube contained the least test substance? Hard to say because the other ones didn't have much of a color, so it didn't seem like there was much protein at all. E. Did the results agree with your initial hypothesis in every case? Yes F. Why or why to?Starches and sugars are helped by protein enzymes and Amylase is an enzyme. Good source of protein, so I thought Albumen would have protein Eggs are a foods, but the Beirut reagent isn't strong enough to pick up small amounts G. If the color change is not as you expected, what might be the reasons? Contamination H. Add another 5 drops of Beirut Reagent to each test tube and stir as before. Do your results change? I didn't notice any change Discussion A. What is the purpose of this exercise? To use color to detect if substances have protein since Beirut reagent would react with a protein to form a purple color B.Why is it important to clean droppers and equipment between chemical uses? To avoid cross contamination C. What other types of foods or substances contain high levels of protein? Meat or fingernails D. Suggest a situation where you might use the Beirut Reagent colorimetric test. It kidney disease E. What other types of analytical procedures detect the presence of proteins? The Lowry Method Exercise 2: Testing for the Presence of Starch in Cells A. What is the test substance? Starch B. Which test tube represents the control? Water C. Why? Water has no starch and it turned amber, so if your color was amber, you ad no starch D.Which test tube contained the most test substance? Potato starch Other than the control, which test tube contained the least test substance? Albumen and amylase E. Did the results agree with your initial hypothesis in each case, why or why not? Known to have starch, and they did. I didn't expect the proteins Yes, potatoes are to have starch sources, but they're not in every natural food source G. If the color change is not as you expected it to be, what might be the reasons? That items I did not think had starch, actually did have it. A. What is the purpose of this exercise?Iodine reacts with carbohydrates to form a dark blue color, so you would know if the substance had carbohydrates based on the color it turned. B.

Besides the control, which test tube contained the least test substance? Potato starch D. Did the results agree with your initial hypothesis in every case? Yes E. Why or why not? The test specifically looks for glucose, so other carbohydrates and starches that don't have glucose, will not show sugar F. What are you conclusions about the results? Glucose will react with Benedicts reagent G. If the color change is not as expected, what might be the reasons? Contamination

USS Tennessee (BB-43) in World War II

USS Tennessee (BB-43) in World War II The lead ship of the Tennessee-class of battleship, USS Tennessee (BB-43) was laid down shortly after the United States entry into World War I (1914-1918). The first class to take advantage of the lessons learned in the conflict, the battleship was not completed until two years after the fighting had ended. Entering the peacetime US Navy, Tennessee spent almost the entirety of its career in the Pacific. The battleship was moored at Pearl Harbor on December 7, 1941, when the  Japanese attacked. Though struck by two bombs, it was not severely damaged and soon joined in operations against the Japanese. Withdrawn in August 1942, Tennessee underwent an eight-month modernization which radically changed the appearance of the battleship and left it better equipped to deal with the challenges presented by World War II (1939-1945) naval warfare. Rejoining the fleet in mid-1943, it took part in the Allies island-hopping campaign across the Pacific and played a role in the Battle of the Surigao Strait. Despite sustaining a kamikaze hit in April 1945, Tennessee remained an active participant in operations through the end of the conflict in August. Design The ninth  class  of dreadnought battleship  (South Carolina, Delaware, Florida,  Wyoming,  New York, Nevada, Pennsylvania,  and  New Mexico) designed for the US Navy, the  Tennessee-class was intended to be an improved version of the preceding  New Mexico-class. The fourth class  to follow the Standard-type concept, which called for ships  that possessed similar operational and tactical characteristics,  the  Tennessee-class was powered by  oil-fired boilers instead of coal and employed an  Ã¢â‚¬Å"all or nothing† armor scheme. This armor approach  called for key  areas of the vessel, such as magazines and engineering, to be heavily protected while less important spaces were left unarmored. Also, Standard-type battleships were required to have  a  minimum top speed of 21 knots and have a tactical turn radius of 700 yards or less.  Ã‚  Ã‚   Designed following the Battle of Jutland, the  Tennessee-class class was the first to take advantage of the lessons learned in the fighting. These included enhanced protection below the waterline as well as fire control systems for both the main and secondary batteries. These were mounted atop two large cage masts. As with the  New Mexicos, the new ships carried twelve 14 guns in four triple turrets and fourteen 5 guns. Unlike its predecessors, the main battery on the  Tennessee-class could elevate its guns to 30 degrees which increased the weapons range by 10,000 yards. Ordered on December 28, 1915, the new class consisted of two ships: USS  Tennessee  (BB-43) and USS  California  (BB-44). Construction Laid down at the New York Naval Shipyard on May 14, 1917, work on  Tennessee  moved forward while the US was engaged in World War I. On April 30, 1919, the new battleship slid down the ways with Helen Roberts, daughter of Tennessee Governor Albert H.Roberts, serving as sponsor. Pressing forward, the yard completed the ship and it entered commission on June 3, 1920 with Captain Richard H. Leigh in command. Finishing fitting out, the battleship ran trials in Long Island Sound that October. As part of this process, one of the ships electrical turbines exploded, injuring two members of the crew.    USS Tennessee  (BB-43) - Overview Nation:  United StatesType:  BattleshipShipyard:  New York Navy YardLaid Down:  May 14, 1917Launched:  April 30, 1919Commissioned:  June 3, 1920Fate:  Sold for scrap Specifications (as built) Displacement:  33,190  tonsLength:  624  ft.Beam:  97.3  ft.Draft:  31  ft.Propulsion:  Turbo-electric transmission  turning 4 propellersSpeed:  21  knotsComplement:  1,083  men Armament (as built) 12  Ãƒâ€" 14 in. gun (4  Ãƒâ€" 3)14 Ãâ€" 5 in. guns2 Ãâ€" 21 in. torpedo tubes Interwar Years   Following standardization trials at Guantanamo Bay in early 1921,  Tennessee  received orders to join the Pacific Fleet. Passing through the Panama Canal, the battleship arrived at San Pedro, CA on June 17. Operating from the West Coast, the battleship moved through annual cycles of peacetime training, maneuvers, and war games. In 1925,  Tennessee  and other battleships from the Pacific Fleet conducted a goodwill cruise to Australia and New Zealand. Four years later, the battleships anti-aircraft armament was enhanced. Following Fleet Problem XXI off Hawaii in 1940,  Tennessee and the Pacific Fleet received orders to shift their base to Pearl Harbor due to increasing tensions with Japan.    World War II Begins On the morning of December 7, 1941,  Tennessee  was moored inside of USS  West Virginia  (BB-48)  along Battleship Row. When the Japanese attacked, Tennessees crew manned the ships anti-aircraft guns but were unable to prevent two bombs from hitting the ship. Additional damage was sustained by flying debris when USS  Arizona  (BB-39) exploded. Trapped by the sunken  West Virginia  for ten days after the attack,  Tennessee  finally moved free and was sent to the West Coast for repairs. Entering Puget Sound Navy Yard, the battleship received needed repairs, additions to its anti-aircraft battery, and new search and fire control radars. Return to Action Departing the yard on February 26, 1942,  Tennessee  conducted training exercises along the West Coast and then patrolled the Pacific. Though it was initially slated to support the landings on  Guadalcanal in early August, its slow speed and high fuel consumption prevented it from joining the invasion force. Instead, Tennessee  returned to Puget Sound for a major modernization program. This saw the battleships superstructure razed and rebuilt, enhancements to its power plant, the trunking of its two funnels into one, additions to the anti-aircraft armament, and incorporation of anti-torpedo protection into the hull. Emerging on May 7, 1943,  Tennessees  appearance was radically changed. Ordered to the Aleutians later that month, the battleship provided gunfire support for landings there. Island Hopping Steaming south that fall, Tennessees guns aided US Marines during the invasion of Tarawa in late November. Following training off California, the battleship returned to action on January 31, 1944, when it opened fired on Kwajalein and then remained offshore to support the landings. With the capture of the island,  Tennessee  rendezvoused USS  New Mexico  (BB-40), USS  Mississippi  (BB-41), and USS  Idaho  (BB-42)  in March to attack targets in the Bismarck Islands. After rehearsals in Hawaiian waters,  Tennessee  joined the invasion force for the Marianas in June. Arriving off Saipan, it struck targets ashore and later covered the landings. In the course of the fighting, the battleship took three hits from Japanese shore batteries which killed 8 and wounded 26. Withdrawing for repairs on June 22, it quickly returned to the area to aid in the invasion of Guam the next month. On September 12,  Tennessee aided Allied operations against Peleliu by attacking the island of Angaur to the south. The following month, the battleship fired in support of General Douglas MacArthurs landings on Leyte in the Philippines. Five days later, on October 25, Tennessee  formed part of Rear Admiral  Jesse Oldendorfs line at the Battle of Surigao Strait. In the fighting, the American battleships inflicted a severe defeat on the enemy as part of the larger Battle of Leyte Gulf. In the wake of the fighting,  Tennessee  returned to Puget Sound for a routine refit. Final Actions Re-entering  the fighting in early 1945,  Tennessee joined Rear Admiral W.H.P. Blandys Iwo Jima bombardment force. Reaching the island, it opened fire on February 16 in an effort to weaken the Japanese defenses. Supporting the landings  three days later, the battleship remained offshore until March 7 when it sailed for Ulithi. There briefly, Tennessee  then moved to take part in the Battle of Okinawa. Tasked with striking targets ashore, the battleship also was routinely threatened by kamikaze attacks. On April 12,  Tennessee  was hit by a kamikaze that killed 23 and wounded 107. Making emergency repairs, the battleship remained off the island until May 1. Steaming to Ulithi, it received permanent repairs.    Arriving back at Okinawa on June 9,  Tennessee  supported the final drives to eliminate Japanese resistance ashore. On June 23, the battleship became Oldendorfs flagship and commenced patrols in the Ryukyus and East China Sea. Raiding the Chinese coast, Tennessee  was operating off Shanghai when the war ended in August.   After covering the landing of occupation forces at Wakayama, Japan, the battleship touched at Yokosuka before returning to the United States via Singapore and the Cape of Good Hope. Arriving at Philadelphia, it began the process of moving into reserve status. Decommissioned on February 14, 1947, Tennessee  remained in reserve for twelve years until being sold for scrap on March 1, 1959.

Cohesion Definition and Examples in Chemistry

Cohesion Definition and Examples in Chemistry The word cohesion comes from the Latin word  cohaerere, which means to stick together or stay together. In chemistry, cohesion is a measure of how well molecules stick to each other or group together.  It is caused by the cohesive  attractive force between like molecules. Cohesion is an intrinsic property of a molecule, determined by its shape, structure, and electric charge distribution. When cohesive molecules approach each other, the electrical attraction between portions of each molecule holds them together. Cohesive forces are responsible for surface tension, the resistance of a surface to rupture when under stress or tension. Examples A common example of cohesion is the behavior of water molecules. Each water molecule can form four  hydrogen bonds with neighbor molecules. The strong Coulomb attraction between the molecules draws them together or makes them sticky. Because the water molecules are more strongly attracted to each other than to other molecules, they form droplets on surfaces (e.g., dew drops) and form a dome when filling a container before spilling over the sides. The surface tension produced by cohesion makes it possible for light objects to float on water without sinking (e.g., water striders walking on water). Another cohesive substance is mercury. Mercury atoms are strongly attracted to each other; they bead together on surfaces. Mercury sticks to itself when it flows. Cohesion  vs. Adhesion Cohesion and adhesion are commonly confused terms. While cohesion refers to the attraction between molecules of the same type, adhesion refers to the attraction between two different types of molecules. A combination of cohesion and adhesion is responsible for capillary action, which is what happens when water climbs up the interior of a thin glass tube or the stem of a plant. Cohesion holds the water molecules together, while adhesion helps the water molecules stick to glass or plant tissue. The smaller the diameter of the tube, the higher water can travel up it. Cohesion and adhesion are also responsible for the meniscus of liquids in glasses. The meniscus of water in a glass is highest where the water is in contact with the glass, forming a curve with its low point in the middle. The adhesion between the water and glass molecules is stronger than the cohesion between the water molecules. Mercury, on the other hand, forms a convex meniscus. The curve formed by the liquid is lowest where the metal touches the glass and highest in the middle. Thats because mercury atoms are more attracted to each other by cohesion than they are to glass by adhesion. Because the shape of the meniscus depends partly on adhesion, it will not have the same curvature if the material is changed. The meniscus of water in a glass tube is more curved than it is in a plastic tube. Some types of glass are treated with a wetting agent or surfactant to reduce the amount of adhesion so that capillary action is reduced and also so that a container delivers more water when it is poured out. Wettability or wetting, the capacity for a liquid to spread out on a surface, is another property affected by cohesion and adhesion.

Changing our lives - Essay Example Moreover, establishing of goals indicates how much progress has been made and how far one is from his destination. Thus, like millions of people, I have also established few goals to be achieved in my life. One of my primary goals is to seek higher professional education from the USA. Since I belong to the Middle East, proceeding to the USA for acquiring Masters Degree in International Relations is my prime ambition. It would be a token of great honor, respect and prestige when my family members, friends and relations would introduce me with others as a foreign qualified young man. It would certainly boost up my morale and I would experience the bewitching fragrance of pride and respect in my mind. Proceeding to the western societies for seeking professional education is really a pleasant dream for the Arab youth, because lucrative jobs and rapid promotions are in wait of such qualified persons on their return in their native country. During my stay in the USA, I will be able to lear n many things related to culture, civilization, society, religion and politics of the world. It is reality beyond suspicion that the USA is a multicultural society, where people belonging to divergent racial, ethnic, regional, religious and cultural groups and communities live together.
