Eventually, the Union was able to take the victory home, which ultimately united both sides. Don’t waste time! Our writers will create an original "The Communication Within The Military" essay for you Create order If the South would have taken the victory, it would have been two distinct sides. The victory of the Civil War has been accredited to the skill of the commanders, the fighting qualities of troops, and resources in men and material, when in truth, it was all thanks to much more than that, such as the militarys intelligence and communication networks. The use of communication in the military was essential for the victory of the Civil War. Although many people may believe that the Union won due to the North having larger and many more companies and factories, larger cities, and a better economy than the South, nevertheless the Union attained the victory due to their communication networks within the military because they gained insight into the other sides locations and etc., looked at tactics they were using and were able to advance. The use of communication in the military was essential to the victory of the war for the North. Whether if it was through the form of letters, spies, an etc. Due to the fact that the main source of communication during the civil war was through letters, people had to advance so that others for whom the letters werent intended for, wouldnt be able to identify the content of what was being said. Many of the times, letters were intercepted, and the information was leaked, which affected either the Union or the Confederacy. Letters evolved over time, using ciphers to uncover the true motive of the letter. Military communication was a prominent aspect to the victory of the Civil War. If the military had no type of communication, they wouldnt have been able to gain insight, know when they were overpowered, and other information that was essentially a necessity. Communication between the military and others was a necessity because they needed to know information, because they could not just go in blindly, they needed to know that they were doing the correct thing. For instance, the Battle at Gettysburg, was not a mere collision of the two armies, the Confederates were going in blindly, but not the Union. The Union had marched 150 miles knowing that they would be there, because of the soldier-spies, that had reported back to them. The Union had spies that communicated back to them, fourteen locally organized groups of spies, had granted the Union the information necessary for the victory at the Battle of Gettysburg. According to the primary source, Sherman, William Tecumseh (1820-1891) to Colonel Robert Crooke Wood, the historical context is that it describes the armies preparedness, during the time of the Battle at Vicksburg. Furthermore, the importance of this document is that it demonstrates how with the communication they held between each other, they were able to continue the war because they had knowledge of what was occurring and if they were ready at the moment. The intended audience is Colonel Robert Crooke Wood and the purpose is to inform the Colonel of his army being well supplied with surgeons, medicines, medical supplies and hospital accommodations. It is a piece of letter that informs about the soldiers battling at the Vicksburg and how he was worried because many of the population had been wounded. The perspective is from William Tecumseh Sherman, who commands an army, and this is important because it is a form of communication, in which was effective because they informed each other whether they were prepared to go to battle. This piece of evidence demonstrates how a method of communication within the military was through letters, which was very so effective because they were able to commu nicate important information such as being prepared to continue going into war. Based on the primary source, Knox, William (1756-1795) Knoxs army diary (incomplete), the historical context is that it is on information about military tactics around the Battle of Germantown. It mentions movements of the army and important events that had occurred. Additionally, the importance of this document is that it represents how the army was doing in terms of ground they covered, materials they were in need of, things they had encountered that was information that could benefit them. The intended audience is that due to it being a diary, it was either for himself or for future references, if anything ever happened to him, or if he had to make reports to someone higher in power or status. The purpose was to record the movements of the army around Philadelphia in September and October 1777. The perspective was from William Knox who was a military officer of the Continental Army and later the U.S. Army, who also served as the 1st United States Secretary of War from 1789 to 1794. It is important because it records important information that was helpful for others in the military, like when it states on September 19, Intelligence recd. of the enemys pushing for Philadelphia the army crossd the Schylkill. According to a primary source, Knox, Henry (1750-1806) to Nicholas Eveleigh, it is another primitive example of how military communication helped the Union be at a stage of benefit. The historical context is that is notes important events that relate to that of war. For instance, it mentions how ships loaded with arms had arrived from France and that Lord Cornwallis nearly captured General Benjamin Lincoln. Moreover, the context is that it informs the intended audience of prominent information such as the shipment of materials that were needed for the continuation of the war. The intended audience was Nicholas Eveleigh, who was an American planter and political leader who was a delegate to the Continental Congress for South Carolina in 1781 and 1782. The purpose is to inform of important details regarding the war and possible information that would help in the future of the war. The perspective is from Henry Knox, the secretary of War and it is important because it lists reports that were prominent to the continuation of the war, such as war materials arriving. If they hadnt received insight on the arrival of the materials, they wouldnt have known, when to continue and when to go pick up the latest arrival. Military communication was also used to let others know of plans that had went through, whether they were struggling or etc. According to a primary source named, Schuyler, Philip John (1733-1804) to James Duane, it demonstrates how the military communicated hardships or celebrations. In addition, the source is a piece of evidence that altered the war because many of those fighting the war, communicated about their losses and victories, in order to tell them details about how the other side was doing and the locations of where they were last at.The historical context is that it goes into great detail of the battle fought in New York, where they had to take the defeat due to them being overwhelmed. It states, abandon the fortress on York Island because the enemys strength was overwhelming. The intended audience is James Duane, a political leader throughout the war. The purpose is to inform the and give a response to James in terms of military actions that were taken and should be take n. It also informs of insight in terms of counties wanting to break away from New York and etc. The perspective is from Philip John Schuyler, a general in the American Revolution, and a United States senator from New York. This is important because it is a letter with intelligence that would benefit the Union, if they had received such important information. According to a primary source, Knox, Henry (1750-1806) to Lucy Knox, it demonstrates how even within family, military information was passed. The historical context is that it reports little activities since the retreat in the Battle of Long Island. It discusses military activities and the effects of such movements. The intended audience is Lucy Knox, the wife of Henry Know, I believe. The purpose is to inform her of important information such as military movements and life. Albeit, the information may seem to broad, in terms of its relation to the topic, the context of the letter was prominent because anyone who might intercept the letter would just see that there is communication between family, therefore, they would not care much of what the information could have potentially said. The perspective is from Henry Knox, a military officer of the Continental Army and later the United States Army, who also served as the 1st United States Secretary of War. It is important because they o ftentimes speculated of military activities that would occur later on, due to the information they had received. They informed one another of details regarding the military and etc. Military communication was more like military intelligence because it helped the military advance and know certain information, such as locations, names of certain people, the events of the current situation and more. According to a secondary source, Military Intelligence During Americas Civil War,it mentioned how a major part of intelligence used during the Civil War was through the following source: spies, scouts, cavalry reconnaissance, captured documents, mail, newspapers, interrogation of enemy prisoners, deserters, refugees, contrabands (fugitive slaves) ordinary civilians, balloonists and signal corps stations of observation. According to a secondary source, Lincoln in the Telegraph Office: Recollections of the United States Military Telegraph Corps during the Civil War, it mentions how essential communication in the military actually was. It discusses how the electric telegraph maintained speedy communication between Washington and armies in distant fields. By the ending of the war, the Union had strung over fifteen hundred miles of military telegraph line, whereas the Confederacy had only about a thousand. It was estimated that 6,500,00 Union messages passed over the wires during the war at a cost of about 40 cents per message. Ciphers were also very commonly used. The service arbitrarily assigned significance to certain words, or arranged words in a false position, throwing in meaningless words to confuse certain readers. According to a secondary source, The secret War for the Union: The Untold Story of Military Intelligence in the Civil War, it mentions how the success was due to the militarys communi cation. It states, for example, the standard depiction of the Battle of Gettysburg as the accidental collision of two armies marching half blindly is found to be true only for the Confederates. Their 150-mile march from the Rappahannock River to Pennsylvania was penetrated by soldier-spies whose findings enabled the pursuing Federals to cross the Potomac simultaneously with the main body of the invaders, and unbeknown to them. The Confederates assumed dangerously dispersed positions across South-Central Pennsylvania, their movements reported by fourteen locally organized groups of citizen-spies and scouts. In conclusion, the communication within the military was essential to the victory of the Union. Without the military communication, the Union would have been unable to win against the Confederates. Although many historians may believe that the Union was able to take the victory to the South due to its tactics or a better sustained economy, nevertheless, the Union was able to become victorious due to the communication networks in the military because they were able to gain insight, they were able to learn certain tactics from the other team, being able to know the location from the other side and etc. Communication network was an aspect of the Civil War that was essentially the victory of the war, due to the reaps of benefits, such as the importance of information.

Central Dogma Paper Free Essays

The Central Dogma of Molecular Biology was founded by Francis Crick in 1958. A central dogma of biology provides an explanation as to how gene expression occurs. The central dogma is the main thesis of molecular inheritance. We will write a custom essay sample on Central Dogma Paper or any similar topic only for you Order Now It states that DNA makes RNA, which makes protein. Genes control the traits by controlling which proteins are made. The process of Central Dogma of Molecular Biology is when DNA transcripts into RNA and then translates into protein. Transcription is the transfer of genetic information from DNA forming into RNA. The differences between DNA and RNA are the sugar that’s in DNA which is called deoxyribose and ribose for RNA which does not have sugar. When DNA replication begins, it begins at a specific point in the DNA molecule called the origin of replication site. The enzyme helicase unwinds and separates a portion of the DNA molecule. After the DNA polymerase separates a portion of the molecule it then initiates the process of replication in which DNA polymerase can add new nucleotides to a pre-existing chain of nucleotides. Therefore, replication begins as an enzyme called primase and it assembles an RNA primer at the origin of the replication site. The RNA primer consists of a sequence of RNA nucleotides, complementary to a section of the DNA strand that is being prepared for replication. The RNA primer is then removed and replaced with a sequence of DNA nucleotides. Then Okazaki fragments are synthesized and the RNA primers are replaced with DNA nucleotides and the individual Okzaki fragments are bonded together into a continuous complementary strand. During transcription deoxyribose nucleic acid is formed into another nucleic acid which is ribonucleic acid or RNA. Transcription begins when RNA polymerase binds onto the double stranded DNA molecule. RNA polymerase moves along the strand of DNA making a complementary single stranded RNA molecule. Here’s a good thing you could remember, take the root word ‘scribe’ out of transcription and think of it was a person who writes copies of important documents because that is what scribe means. Next is translation, it is the process of using the code in RNA to put together the protein and translation is a word that describes the transfer of information from one to another. Translation begins when messenger RNA binds to the ribosome. The RNA passes along the ribosome and brings out 3 nucleotides at a time. While that’s happening the amino acid that is being carried is also being transferred to the amino acid chain. After that is done the ribosomal complex falls apart and the protein is released into a cell. During protein synthesis, amino acids build a protein molecule that’s, of course, called protein synthesis. Synthesis means ‘putting together’, so that is a good way to remember protein synthesis. Protein synthesis is the cellular process of building proteins. Translation has a part of the central dogma that is also included in protein synthesis and transcription is not. Translation is just the decoding of RNA to make a chain of amino acids that will then, later, turn into protein. Overall in central dogma, DNA is simply the instructions to making proteins.

South-East Asia

Question: Describe about the South-East Asia? Answer: Rising location: In the region of South East Asia, the rising countries for appropriate business locations are China, Dubai, India, Bangladesh and some part of Afghanistan. These countries are well developed and still developing in the business field, especially the countries like India and China, where the population is very high, in these two countries consumers are very good in numbers. New industries and Technologies: In this region small and medium business achieved huge success.

Welfare Essays (824 words) - Federal Assistance In The United States

Welfare Welfare is a government program that provides money, medical care, food, housing, and other things that people need in order to survive. People who can receive help from these welfare programs are children, elders, disabled, and others who cannot support their families on their current income. Another name for welfare is public assistance. There are many organizations that supply this public assistance. Such as Salvation Army and other groups. Public assistance benefits help many people who live below the poverty line, an income level is established for families. If your income is below this you would be eligible to receive this help. Welfare in the United States Federal and state governments in the Unites States serve the poor people through about 60 public assistance programs. Most people receive help through one of the four major programs. These programs are Medicaid, Aid to families with dependant Children, Social Security, or Supplemental Security, or the food stamps program. I will discuss the four programs individually. Medicaid provides free medical care to the poor people. Funds vary from state to state. In some situations, people who may be able to pay daily needs, but can't afford large medical bills may also be able to receive Medicaid. Some services paid for are bills such as doctor's visits and nursing home care. Most Medicaid funding comes from the federal government. The rest is supplied by the state. Each state runs their own Medicaid program. A.F.D.C. provides cash benefits to dependent children and the parents or the guardians taking care of them. Most families that qualify for A.F.D.C. have just one parent in the home. About 80 percent of these families are headed by a woman. A.F.D.C. also pays benefits to two-parent families if both parents are unemployed. Most A.F.D.C. funding comes from the federal government. The states provide the rest of the money and administer the program. The sizes of families' payment vary from state to state. Next is Social Security Income. This provides financial Aid to people in need who are at least 65 years old, blind, or disabled. The federal government finances and administers social security income programs in most states, though some states supply the federal payment and are able to run their own programs. Finally, the Food Stamp Program helps low-income households buy more and better food than they could otherwise afford. Each participating household receives a certain number of coupons called food stamps. The stamps are issued by the federal government. The number of stamps a household receives varies with the family's size, income, and expenses. Cooperating grocery stores accept the stamps like money for food purchases only. There are other programs such as energy assistance and public housing. Energy assistance, which is federally financed but administered by the states, helps people pay fuel bills. Public housing provides low cost rental apartments in government owned buildings. State and local governments fund and administer their own general assistance programs. These programs provide financial aid for needy people who do not qualify for other types of welfare. People waiting to receive assistance from other programs also may get temporary emergency aid from general assistance. Back in the early days, welfare resembled the English system. Social governments were responsible for helping the poor. But the colonies and later the states, sometimes helped the local government provide aid. The first federal welfare program, began after the Revolutionary War, they provided pensions to war veterans. During the Civil War these pensions were expanded to cover soldiers' widows and orphans. In the early 1900's, primary responsibility for providing welfare benefits shifted from local to state governments. During these years, states enacted programs to aid dependent children and the elderly. The criticisms of welfare ranges over a number of social and economic issues. Some people criticize welfare programs for not providing high enough benefits to eliminate poverty. Spending on welfare would have to increase greatly to eliminate poverty, and many people believe the cost is already too high. Many critics of the welfare system charge that providing a steady income to needy people encourages idleness. Actually, most welfare benefits go to elderly, blind, and disabled people and mothers with young children. But welfare does discourage some recipients from working harder by reducing benefits if their income increases. Many people also criticize the welfare system for being too complex and costly to administer. Each program has its own eligibility requirements and ways of calculating benefits, and these rules vary from state to state. Public officials collect detailed information about applicants to determine their eligibility for benefits. This process is time-consuming and costly. Some people cheat the system by not reporting all the income they earn. But

Free Essays on The Goal

The Goal Book Review I really enjoyed reading this book. It’s so unlike any book I’ve had to read for class before, except for novels that we read in English class, of course. It was sort of a text book, but with a story. And an interesting plot, no less. I liked how Goldratt got me all involved in not only Alex’s job at the plant, but his personal life as well. I’ll have to admit that as I was getting into the story, it was easy to guess that the book will conclude with a happy ending. I was enthralled anyway, though. I thought this book was so good, it actually only took me three days to read. I thought that was pretty good considering all the stuff a person does in one day. What got me so interested is the way the story is written. Goldratt kept me trying to guess what Alex was going to do next, and that kept me reading into the next chapter. And not only did he keep me guessing about how in the world Alex was going to save the plant, he also kept me guessing about how Julie was going to react to all of it. But Julie’s reaction is typical. I’m sure I would feel the same as her as well. I think it’s hard when one spouse stays at home while the other one works long hours. What I enjoyed most about this novel is the fact it seemed so real. We’ve got this ordinary guy, who’s an engineer like me. My husband, who is actually an industrial engineer, got excited when he saw me reading this book. He had read it in his intro class and really like it as well. Though he said they read it over the course of several months. Anyway, this ordinary guy has real life problems just like everyone else in the world. There are problems with his job, working too hard, and work cutting into his personal life. I think one great thing that this book tried to teach is how to balance work and life. Sure, we all want to do well in our careers and move ourselves up the ladder, but there really needs to be some s... Free Essays on The Goal Free Essays on The Goal Eliyahu M. Goldratt’s The Goal When I first started reading The Goal, I felt that I couldn’t relate to the topic and setting of the book, since I am still an undergraduate business student who has not even begun studying a specific area of business. But the more and more I read, the more I became interested in the story and the more involved I became in rooting for the success of the plant. Never before have I really thought about the world of manufacturing, especially managing a plant that produces industrial parts. As a marketing major, I think I have always felt that manufacturing was a completely separate part of business like the financial aspects of business (accounting and finance). The Goal brought into perspective the problems that can arise from the different demands on the manufacturing process, especially the differences in goals among the different parts of a business. I never realized, until reading this book, the pressures that marketing puts on manufacturing and the consequences of the pressures to produce more and more to sell at lower and lower costs in order to gain customers. I also thought it was interesting that a business could have been running for so long with different goals- one department was concerned with inventory, one department was concerned with cost, and one department was focused on pleasing customers and trying to sell as many orders as possible. When Jonah helped Alex focus in on the real goal of the plant, to make money, it seemed to me that a goal so simple should have been obvious to everyone in the company from the start. I now realize the importance of communication within an organization on all levels, especially when it comes to matters of money and production, since those two factors almost drove Alex’s plant out of business. In conclusion, I feel that this was an extremely valuable and pleasant read for me as a business student, and I would highly recommend th...

Marketing the Bad Boys of the NFL Research Paper

Marketing the Bad Boys of the NFL - Research Paper Example The Super Bowl is the most-watched American television broadcast. Super Bowl XLIV, played in 2010 between the New Orleans Saints and the Indianapolis Colts, became the most-watched American television program in history, drawing an average audience of 106.5 million viewers and taking over the spot held for 27 years by the final episode of MASH. Sunday Night Football has become the most popular sow in prime-time television this season, dominating the overall Nielsen ratings, with the highest average viewership for a prime-time NFL package in 14 years. Sunday, December 6th's Pittsburgh-Baltimore classic, seen in nearly 23 million homes, was the most-watched show on television in the first week of December 2010, as Sunday Night Football has been since the start of the 2010 season. The NFL is so violent that the league, the US military, and neurologists recently held a conference to investigate head injuries and concussions and determine if equipment or rule changes could protect the players better. Remarkably, the military was involved because NFL players suffer the same type and frequency of injuries as soldiers in combat. That is an astonishing correlation – the NFL is as violent as combat in Afghanistan and Iraq. NFL is so violent that players regularly suffer 'career-ending' injuries that leave them crippled for life. It is so violent that Daryl Stingley was paralyzed for life in a game, and in pre-season games at that. In a meaningless preseason game New England Patriots quarterback Steve Grogan overthrew wide receiver Darryl Stingley, Jack Tatum of the Oakland Raiders, known for his vicious hits, nailed Stingley while he was in the air, snapping vertebrae in his neck. Stingley was a quadriplegic for the rest of his life. He died in April of 2007 at the age of 55 of heart disease and pneumonia complicated by his quadriplegia. NFL also has a propensity for criminality and criminal violence.

Write a complete laboratory report that covers all three experiments Essay - 1

Write a complete laboratory report that covers all three experiments for Lab 2 Water Quality and Contamination - Essay Example ater comprises at least 70% of the earth, only about 1% percent of this water is fresh water, and the rest 99% of the water is non-usable salty water. The process of purifying salty water to make it usable fresh water is extremely complicated and expensive and as such, people, many animals, and plants have to survive on the 1%. There are three sources of fresh water used by people and animals; ground water, surface water, and aquifers. Surface water includes water that collects on the ground through the process of precipitation and which does not evaporate back to the atmosphere or even infiltrates to the ground. This water collects in such places such as rivers, lakes, among others. Ground water on the other hand settles underneath the ground, and is stored in pores, fractures, or solid rock underneath the earth surface. This water collects in these places through the infiltration process. Aquifers on the other hand are areas where water collects such as in sand, gravel or permeable rock. Although rainwater is pure, it gets contaminated very fast, especially after it touches the ground through man made, natural and animal pollutants. Ground pollutants travel from one place to another through streams, rivers, or ground water while others are available in the air. Man-made pollutants include motor oil, petrol and diesel, acidic chemicals, among others. There are many dangers of consuming contaminated water, especially the potential of these impurities in causing diseases. Poisons, disease causing agents and toxins can reside in water, and adversely affect people. Medics believe that contaminated water such as toxins and lead acid chemicals are responsible for majority of cancers affecting many people today. It is because of these impurities and dangers associated with contaminated water that water purification becomes
