Definition of the Word Courage Essay Example | Topics and Well Written Essays - 500 words

Definition of the Word Courage - Essay Example The average person derives an image of a superhero when thinking about courage. However, that a limited view of what courage means. This is because it can be applied to so many other aspects of life. The second half of the definition in regards to negative forces is what allows for individual perspective on the word. For example, courage can pertain to a person stopping a gunman from shooting another victim despite the immense danger he or she faces in possibly getting maimed or dying in the process. On the other hand, courage can be reflected in the depths of an individual who recently became crippled and has to face the pain, difficulty, and fear of starting life in a new way with new challenges. Both situations involve a form of evil to some extent and to be courageous is appropriately applied to the people involved.   As the discussion highlights  the situation also does not have to be a severe one that radically changes peoples’ lives. There is no indication in the definition of courage that there has to be a big or massive negative situation that happens to someone for it to maintain its context. Courage can be applied to as little a situation as giving a successful speech in front of a classroom of students or having the courage to try something new whether it is a type of food or physical activity.

Agricultural Production in Ancient Civilizations Essay Example for Free

Agricultural Production in Ancient Civilizations Essay During the period of 500 C. E – 1000 C. E. ancient civilizations in North and South America and China cultivated and gradually moved from the hunting and gathering lifestyles. These civilizations drifted towards food collection and then farming. This approach, crops and attitudes toward agriculture varied with culture. With the Native Americans and the Ancient Chinese during 500 C. E – 1000 C. E. have both differences and similarities towards agricultural production. Document 1, tells of a story about how Maria Manuela de Cora (an Inca Author) passes along ancient legends. One that is called â€Å"Seeds† that says that one day the son of the sun kills a child that was made by the sun. The son of the sun got scared of the anger of his father and scattered about the world the pieces of his murdered brother. It tells that his body parts like his teeth grew corn. This would be a story about the creation of corn, why it was there and how. However, document 7 talks of an Ancient Chinese Legend. This talks more about that fact that if you took the weeds you could fertilize the farmer’s crops. With each story tells something to do with farming. How that one, thing is made or how to make their crops better. Document 5, is a diagram of a hunting scene and peasants working in a field in Ancient China. This illustration gave a reason for historians to track the development of tool- and weapon making in organization in agrarian and artisan production as well as the leisure activities of officials and the landed elites. With document 3 talks about Mesoamerican origins. Historians talk about that current archaeological evidence cannot pinpoint a single location where Indian agriculture began or determine precisely why the Indians became agriculturists. They did though have records that suggested that the cultivation and domestication of plants. With the painting and the records gave historians a better view of each hunting scene and peasants working in fields. During the period of 500 C. E – 1000 C. E. ancient civilizations in North and South America and China cultivated and gradually moved from the hunting and gathering lifestyles. These civilizations drifted towards food collection and then farming. With this approach, crops and attitudes toward agriculture varied with culture. With the Native Americans and the Ancient Chinese during 500 C. E – 1000 C. E. have both differences and similarities towards agricultural production. Showing that China was more into the facts then stories like Mesoamerica to explain the reasoning of agricultural in both of China and Native Americans.

Role Of E Coli And Salmonella Food Spoilage Biology Essay

Role Of E Coli And Salmonella Food Spoilage Biology Essay Food is sometimes contaminated with pathogenic microorganisms, there are many sort of Pathogenic bacteria it is very dangers for human, animal, salmonella one of them, it is frequently found in fowl ,eggs ,raw approved by pets similar to turtles and birds, salmonella is bacterium which is one of the commonest causes of food spoilage worldwide , there are more than 2,000 dissimilar sorts of salmonella , but with the omission of the little which typhoid or parity ,fever the sickness they cause is related, also there is a common sort of bacteria call E.coli it is akin to beef and vegetables , E.coli is short for the medical dumpy Escherichia coli is short for thing about these bacteria and lots of other bacteria is that theyre not constantly harmful to you. (1,8) E.coli generally lives indoors your intestines where it helps your body split down and digest the food you eat , Ecoli be able to get from the insides into the blood , this is a rare sickness but it can cause a extremely serious infection food is the commonest sources of salmonella for humans . the food may have been contaminated bacteria the source, animal or bird was infected salmonella is common with chickens some studies in 1990 showing that about 50%of of frozen and fresh chicken hold the bacteria .infections in dairy herds may show the way to contamination of milk.( 4,7 ) Outbreaks of gastroenteritis suitable to contaminated food have been reported in extra parts of the world. The probable causes of these outbreaks were suitable to the consumption of food contaminated with pathogens bacteria. Studies from many countries have given away that the microbiological quality of food manufactured for make use of in foods and drinks might be a cause for concern. (1) Ecoli was discovered by German pediatrician and bacteriologist Theodor Escherichia in 1885, and is now classified as piece of the enterobacteriacea. (5) Salmonella was discovered by D.E salmon, the American veterinary pathologist who original described salmonella cholera sues in 1900. (5) In fact several microorganisms can stay alive in food, even though food is very important to the maintenance of life, it can also be conscientious for ill health. (1) Structure and function of E coli Bacteria The find structure of bacterial cells has been studied in some detail using electron microscopy of whole cells and cells broken up into separate components.(4) 1.1 the organism and its characteristics Escherichia coli is a kind of gram negative bacteria, this is usually found living indoors the lower intestine of human beings as well as animals , there are quite a few different strains of E coli bacteria , most of which are practically, harmless.( 10 ) Although they form a very minor component of the intestinal flora, the E coli bacteria aid in the digestion and break down of the ingested food. (6) E coli is the type of genus, it is a catalase-positive, oxidase -negative, fermentative, short, gram-negative, non-sporing rod, although it ferments the sugar lactose. The following figure illustrates  the size of  bacteria  under the  electron microscope. (2) Figure1.1-electron micrograph of E coli. 1.1.1-solation and identification of the isolates Colonies were isolated from the Trypticase Soy Agar plates (TSA) (Oxoid UK) and Triple Sugar Iron slants (TSI) (Oxoid UK) and incubated at 37oC for 24 hour. The isolated bacterial was identified by cultural morphology, Gram-stain and biochemically, the colonies that showed typical reaction in TSI and positive for cytochrom oxidase test and catalase test were confirmed by using Analytical Profile Index 20E (API 20E). The colonies which are gives Gram positive cocci identified by used catalase, coagulase and DNase test. (2) 1.1.2 What these bacteria do is that they produce loads of vitamin Amino acids and other growth factors which are immediately absorbed and used by the body. The Ecoli bacteria that colonize in the lower intestine by adhering to intestinal lumen. (9) However, some strains of E coli are also able of causing deadly health problems such as severe stomach characterized by cramps and belly pain, vomiting and severe diarrhea.(10) 1.2- Structure and function of salmonella 1.2.1 -the organism and its characteristics According to the(Adams, M and Moss, M ,1995) salmonella bacteria are the most common cause of food borne sickness in the united states there are more than 2500 serotypes of salmonella, only some of which cause illness in humans.(1 ) Salmonellas are members of the enterbacteracese they are gram negative, non-spore forming rods (typically o,5 m by 1.3m) which are faculatively anaerobic , catalase -positive, oxidise-negative. The following figure illustrates  the size of  bacteria  under the  electron microscope (4) Figure1.2.1 electron micrograph of salmonella 2-Similarities E.coli was discovered by German pediatrician and bacteriologist Theodor Escherichia in 1885, and is now classified as piece of the Enterobacteriace family.(1) the largest part E.coli strains are harmless, but some such as serotype 0157:H7, but some such as serotype 0157:H7, can cause serious food poisoning in humans.(2) Salmonella is closely related the Escherichia genus, and some classified as part of the enterobacteriace.( 1 ) Many Ecoli and salmonellas are responsible for a number of different clinical syndromes, grouped here as enteritis and systemic disease. bad stomach cramps and belly pain, vomiting, diarrhea, sometimes with blood in it two very bad strain of Ecoli and salmonella were found in fresh spinach in 2006. ( 2 ) on the other hand, some strains of e coli and salmonella are also capable of causing deadly health problems such as severe stomach upsets characterized by cramps and belly pain, vomiting and severe diarrhea.( 4 ) 3-Difference -E coli can be differenced from salmonella on the basis of a figure of sugar-fermentation, and other biochemical tests.(10) -E. coli is indole positive or methyl red positive, but salmonella was negative. -E.coli is atypical mesophile growing from 7-10c up to 50c with an optimum around 37c. (3) -Contamination of eggs especially with salmonellas is a long-recognized problem but in the most cases this was due to contamination of the eggshell. (4) -furthermore biochemical tests between E coli and salmonella is difference, so typically significant group of tests used for the ability to produce: i) Indole from tryptophan. ii) Sufficient acid to reduce PH. (8) -Any member of the genus salmonella presents some degree of hazard to human health, such as S.gallinarum, typhi and pullorum. (3) Discussion In many previous studies on the quality food microbiology criteria for the food and intake water to these recommended by world health organization. This is because lots of countries do not have specific notional microbiological for food spoilage. Although, many good bacteria are needed in your body to assist it work properly, a few of these bacteria assist you digest food (normal flour), and keep your skin clean. However, other types of bacteria can make you ill, also convinced bacteria invade your badly and attack, causing infection. Good hygiene and good handling practices are all prerequisites to the manufacture of good value food.

How Young People Use Sunscreen :: Skin Protection

How Young People Use Sunscreen One of the biggest aspects of college is learning to how to live on one’s own. Protecting one’s self is a large part of this. Hygiene in the communal showers, eating the right foods, exercising the right amount, avoiding substance abuse and practicing safe sex are just a few of things a person in college must look out for. But what about the sun? Lost among the shuffle is protection from the piercing ultraviolet rays from our closest star. When compared against other dangers such as obesity or alcoholism, melanoma seems to hold its own. So what are kids doing to protect themselves? There are very simple ways to protect ourselves from the sun. A hat is useful and sunglasses make it easier on our eyes. One often overlooked alternative is sunscreen. Why don’t more people use it? A study conducted eight years ago interviewed people of all ages and backgrounds in an effort to study sunbathing and solar protection habits. This study found that roughly only half of the people who sunbathe with any frequency use sunscreen. When broken down into demographics, one can see that the percentages are lower for the 16-25 year old group than in any other group interviewed (Koh). These numbers clearly indicate that not enough young people are using sunscreen. Why not? Any person that looks at me can tell that I’m too Irish from my own good. While this may have an advantage or two, it presents a serious problem in an environment like Miami. Someone like me cannot last long in this sun. How do I protect myself for extended periods of time? That’s right, SPF 50. Go on, laugh, but I have never burned when I have used it. What about other, less Irish people? At the end of August I took a trip to South Beach with a group of seven people. There were several Miami natives, but others hailed from the North. Yet only I wore sunscreen. In June a dozen of my friends and I went on a week-long trip to Ocean City. After the first day at the beach, nine of my friends suffered from sun poisoning and spent the majority of the trip indoors. So why don’t kids use sunscreen? Is it something that comes with maturity? Or must it be learned through experience? I personally learned through experience. I fell asleep on a boat once and woke up with some of the worst sunburn an afternoon sun can give you.

Research Paper on a Tale of Two Cities

Formal Plot Summary Lucie Manette is a central character in the novel. She tends to affect the characters around her in a brightening manor. For instance she mends her father’s psyche through her unconditional love. Because of her ability to affect others in a liberating sense she attracts other characters such as Stryver, Charles Darnay, and Sydney Carton. She also is able to bring light to the life of family friend Jarvis Lorry. Another way Lucie is central is through her constant placement in â€Å"love triangles† the most obvious being Carton and Darnay. A second triangle she finds herself in is between Dr. Manette and Darnay. Sydney Carton is the protagonist of the novel. He dies by the blade of the guillotine to save Darnay. Carton is introduced in the beginning of the novel as an indifferent, drunkard of a lawyer. He seeks no true meaning to life or find pursuit in attaining any future goals. He is a complex character, because he ends up finding meaning, when he falls in love with Lucie Manette. He works early hours for Stryver while wearing sopping towels. He has thrown away much potential, yet he retains sympathy from people by fulfilling a promise to Lucie. Another dimension to Sydney Carton is that he is a social outcast. He has no place in the English class system. Yet, when Carton goes to Paris he becomes a new person. He finds fulfillment in life and in his death. Charles Darnay plays the role of romantic lead. He becomes the love interest and eventually the husband of Lucie. Darnay’s real name is revealed to Dr. Mannette in exchange for his daughter’s hand in marriage—his name is revealed to be St. Evremonde. Darnay is a symbol of sacrifice, when he gives up his home in France to pursue a life in England. He gives up his old privileges to become a tutor of the French language. Dr. Manette spent eighteen years in jail. To keep his mind in prison, he developed a skill in shoemaking. Dr. Manette suffers from spells of amnesia. Throughout the novel Dr. Manette grows as a character. He develops strength and confidence that he had lost in solitary confinement. An example of this is his ability to reason with the revolutionaries to keep Darnay alive. Five years later Charles Darnay is introduced on the stand of a court house. He is being tried for treason. Lorry and Lucie testify to save Darnay, but he saved by his Lawyer Stryver. The case that was made to save Darnay was that he could not possibly be spy because of his resemblance to Sydney Carton—an indifferent lawyer. As this is going on, Darnay, proposes to Lucie. They become engaged. Sydney Carton also reveals his love for Lucie. He understand that he cannot have her, so he promises to give his life for anyone sacred to her. While the marriage ceremony is commencing it is told to Dr. Manette that there were hidden papers found in a prison. This event sends Dr. Manette into shock for several days. Earlier in the day Darnay tells Dr. Manette his true name—Charles St. Evremonde. The French Revolution has now broken out, it is 1789. Defarge has lead an attack on the Bastille while his wife controls the revolutionary women. They burn down everything related with the St. Evremonde name. Gabelle, father of the killed child, is imprisoned. Darnay hears of this tragic event and rushes to France. While he is attempting to help Gabelle, Darnay is seized by revolutionaries as an aristocrat. Dr. Manette has much influence because of his time spent in the Bastille, he is able to visit Darnay, but no free him. Fifteen months later Darnay is brought up before the French Tribunal. As a result of Dr Manette and Gabelles’ testimonies he is set free. As Darnay is leaving, he is rearrested due to the efforts of Madame and Monsieur Defarge. Sydney Carton appears and informs Travis Lorry. Sydney Carton forces John Basard (he once testified against Darnay) to cooperate with him, or he’d reveal Basards illegal maneuvers of spying on prisoners. The following day Carton goes to visit Darnay, drugs him, and takes his clothes. Carton planned on fulfilling his promise to Lucie. Barsard rushes Darnay’s unconscious body out of jail to be with his family and flee safely. Madame Defarge goes to Manette’s apartment to kill Lucie, but meets Miss Pross. Miss Pross fights off Defarge who fires the pistol killing herself. Carton meets the guillotine. He is calm and is optimistic of his death. He dies with a face that is at peace. One major conflict in the novel is between Charles Darnay and his uncle. The conflict is external. There is a fight about Darnay selling the old establishment in France. Darnay’s uncle curses him. There is no resolution to this conflict, but Darnay’s uncle meets his demise when he is stabbed to death by Gabelle. One major internal conflict is between Carton and his inability to pursue any goals. He is revealed as a waste. He becomes the saddest story, when he is born with all the potential in the world but does nothing with it. The conflict is finally resolved when he keeps his promise to Lucie, when he takes his life for Darnay. He is able to come to terms and feel at peace. Sacrifice becomes a central theme in the novel. One example is when Darnay gives up his aristocratic lifestyle to pursue life in England. Another example is Carton when he sacrifices his life in order to save Darnay, so that Darnay can flee the country with Lucie. Another obvious them in A Tale of Two Cities is love and hate. An obvious example of love is Miss Pross protecting Lucie’s life by fighting off Madame Defarge. Miss Pross risks her own life to save another. The best example of love is Carton’s promise to Lucie. In order to promise his life to Lucie, he had to love someone more than himself. An example of hate is Madame Defarge’s attempts to kill those who had relations with Darnay. She wanted vengeance, which is a byproduct of hate. Her hate for aristocracy drives her to almost successfully getting Darnay killed by the guillotine. Another major theme which should be mentioned is death. Carton has to die in order for Darnayto live. Throughout the novel there is speak of death and violence. There were multiple descriptions in the novel of death by guillotine and scenes of the bloodshed due to revolutionary violence. One example I was able to clearly recognize was the guillotine. It symbolized death. Such as when it killed Carton. It also symbolized revolutionary violence. Evidence of this was whenever speak of revolutionary actions were shown, the guillotine was mentioned. Another example was Madame Defarge’s knitting. She would knit the names of the people she desired to kill. It was a symbol of their fate. Her knitting was a symbol of fate because every time she knitted someone’s name into her pattern, they would be marked to die. My personal reaction to the book was that it was very complicated to understand. Dickens’ word usage made simple sentences much too complicated to understand. I had to read the book with a dictionary. It took me from anywhere between twenty and thirty minutes to read eight to nine pages. Although I struggled much with the novel, I enjoyed it. My research paper will be concentrated on the complexity of Sydney Carton. He constantly changed my view of him in the novel. At one point I might dislike him, but then in another section I gained understanding for him. I feel that I will be centering my thesis on paralleling the lives and views of both Sydney Carton and Charles Dickens. Works Cited Dickens, Charles. A Tale of Two Cities.

Will Rogers Essays - American Old West, Cowboys, Rodeo, Free Essays

Will Rogers Essays - American Old West, Cowboys, Rodeo, Free Essays Will Rogers Will Rogers was a cowboy that did rope tricks. He was loved by the crowds that watched him. ?Onto the stage ambled a friendly-faced, tousled-haired man wearing a cowboy getup and carrying a collection of lassos in his hand. He smiled at the audience, then threw out one of the ropes, twirling it in a circle in preparation for one of the complicated rope tricks he was hired to perform. But as he went into the trick, he miscalculated the size of the small stage, and the rope whacked into the backdrop and fell to the ground with a loud thud. The audience was silent as the obviously embarrassed cowboy reached down and picked it up. Without a word, he tried the trick a second time. Again, the rope slammed loudly onto the stage floor. Show directors had a standard way of dealing with such a disasters-get the performer away from the audience as fast as possible, or ?give?em the hook? in the theater parlance. As the curtain came down on the rope twirler, Buck thought sadly that the curtain had probably been drawn on the young hopeful?s career. To his surprise, the audience was thinking differently. Instead of hurling jeers and catcalls, people here and there began to clap, and soon the entire theater was filled with the sound of applauses. The curtain went back up, but when the audience saw another musical number was next, they booed and hooted, demanding the return of the clumsy cowboy. They did not care that he had botched his act-there was something so appealing about him that the audience just wanted to see more of him. -2 The curtain went back down; after a few tense moments, it rose again as the cowboy, his smile even broader this time out, sauntered back onstage. The act went well this time out, and the audience responded with a standing ovation. Buck was impressed. It did not take too much imagination to recognize that he had found a real crowd pleaser.?1 In 1915, Will was becoming a follies star. He quickly got bored of his act. ?By 1915, Rogers had become a staple of the vaudeville circuit. He had no trouble getting jobs, and his act inevitably drew raves from the critics and the public alike. Recognition and good pay were not quite enough for Rogers, however, for he quickly grew bored doing the same type of act over and over. A man of tremendous energy, Rogers always had to have new challenges in order to maintain the level of concentration he needed to be at his absolute best as a performer.?2 War World I helped Will?s career. He became a cracker-box humorist. ?In the Follies his famous line, ?Well, all I know is what I read in the papers,? introduced new highlights which he learned to bring into homely but unexpected focus. ?I never told a story in my life,? he once said. ?What little humor I?ve got pertains to now.? What the Civil War had been to earlier cracker-box humorists, and the Spanish-American War to Mr. Dooley, the First World War became to the rising star of Will Rogers-and continued through its sequels from the Peace Conference (?The United States never lost a war or won a conference?) to the Coolidge bull market (?Two thirds of the people promote while one-third provide?). As a Westerner, Rogers understood the Virginian?s famous formula, ?When you say that, smile!? With a jester?s immunity he deflated rhetoric, buncombe, and group smugness; and surprisingly few tempers were lost. ?3 -3 Will started writhing newspaper articles in 1922. He was a popular writer. ? In November 1922 Rogers had begun a long series of weekly articles for The New York Times and the Times from London, July 29, 1926, about Lady Astor?s visit to Manhattan, set the tradition of his daily telegram, one terse paragraph that curbed his genial wordiness and proved to be his most popular medium. Syndication carried it to some 350 newspapers, with an estimated 40,000,000 readers. Writing almost constantly of politics, and belonging nominally to the Democratic party (because ?it?s funnier to be a Democrat?), Rogers wisely chose the nonpartisan point of view.?4 Will loved to travel. Even if it could cost him his life. ?In the late summer of 1935 he planned a flight north to the Orient with his fellow Oklahoman, Wiley Post [q.v.]. About fifteen miles from Point Barrow, Alaska, on Aug. 15, their monoplane developed engine trouble and, with an Eskimo hunter
