Microbiology Bioremediation - Essay Example [1] There are a number of cost/efficiency advantages to bioremediation, which can be employed in areas that are inaccessible without excavation. [1] Like hydrocarbon spills or oil spills (specifically, petrol spills) or certain chlorinated solvents may contaminate groundwater, and introducing the appropriate electron acceptor or electron donor amendment, as appropriate, may significantly reduce contaminant concentrations after a lag time allowing for acclimation. [1] An oil spill is the unintentional release of a liquid petroleum hydrocarbon into the environment as a result of human activity. [2] After a spill, hydrocarbons are subjected to physicochemical processes such as evaporation or photochemical oxidation which produce changes in oil composition. But the most important process acting on the spilled oil is biodegradation. [3] There are several ways to clean-up an oil spill in the given scenario and in situ treatment. Microbial Biodegradation through Methanogenesis, using the glycolysis pathway is one way. Bioremediation and Biotransformation methods endeavor to harness the astonishing, naturally occurring, microbial catabolic diversity to degrade, transform or accumulate a huge range of compounds including hydrocarbons such as oil. [1] Bacteria are minute unicellular microorganism, the smallest one having all the necessary protoplasmic equipment for growth and self-multiplication at the expense of available food stuff (Smith,1980) such as hydrocarbon fuel. Every bacterium is covered with a cell membrane known as the plasma membrane which separates it from the cytoplasm of the bacterial cell. Composed of phospholipids and proteins, the plasma membrane is the site of important enzyme systems, including the respiratory enzyme systems or cytochrome enzymes (Smith,1980). In regulating the passage of food materials, like oil, and metabolic by-products between the interior of the cell (where metabolic activities are carried on) and the

Things Fall Apart Okonkwos Tragic Flaw English Literature Essay

Things Fall Apart Okonkwos Tragic Flaw English Literature Essay Things Fall Apart is a tragic story about a man who comes into conflict against himself to prove himself worthy of his tribe. A tragic hero is the main character in a tragedy that normally makes a mistake and ends up defeated. The four main criteria for a story to have a tragic hero would be that the main character has a flaw but has some goodness, he is the protagonist of the story, he is noble or exhibits wisdom, and he suffers a reversal of fortune in the end because of his tragic flaw. A tragic flaw of a character is the flaw of the main character that will eventually bring him down. The main character, Okonkwo, meets each of the four criteria to be a tragic hero. His flaw would be that he is violent but he does have some good. He cares for his family; he wants his son Nwoye, to be tough and hardworking like him. Moreover, he wanted his daughter, Ezinma, to be safe. He is a protagonist of the story because he is the main character, he is a hero, and in addition, he is tough. Okon kwo also exhibits wisdom because he is a leader. He is a great warrior and everyone looks up to him to keep them safe. In the end, Okonkwos flaw of violence and overconfidence got out of control. He became too violent when the church took over. The people of his tribe turned to the church instead of following him so he decided to take action and kill a messenger. The commissioner of the church came after him but he had already hanged himself. Therefore, Okonkwo, meeting every rule, is a tragic hero (Wikipedia.org). Okonkwo is an impatient, violent person. When things do not go the way he wants them to go, he cannot just talk it out with someone, he turned to violence whenever he was angry and could not get his words out quickly enough, and he would use his fists. He had no patience with unsuccessful men (Achebe 8). He is arrogant and attributes excessive pride; he feels that everyone should listen to him and that he rules his whole clan and even his family. He also beat his wife during the Week of Peace, when she returned he beat her heavily. In his anger he had forgotten that it was the Week of Peace (Achebe 31). Okonkwo also had some goodness in him. Ezinma became very ill and shivered in the night, Okonkwo makes a medicine for her and she gets better. He cares for his family even though he does not want to show it. He hopes for his son to grow tough and strong and not end up like his lazy father. Ikemefuna was a boy from Mbaino who was sent to Umuofia because his father had killed a woman fr om Umuofia. He was to stay with Okonkwo for three years then was to be killed. Okonkwo treated him like he was his own son, they respected each other and Ikemefuna was a hard worker. Okonkwo liked this about him; he was not like his father or his own son Nwoye. The second main rule to be a tragic character would be that he is the protagonist of the story. A protagonist is the main character in a literary work who is a champion of a cause or course of action. Okonkwo is the protagonist of the story because he is the main character and he is the hero of the story. In the first chapter of Things Fall Apart, Chinua Achebe describes Okonkwo as a great and fierce warrior. He was a great, famous wrestler and his fame had grown a lot over the years. There was another great, undefeated wrestler called Amalinze the Cat that Okonkwo threw in a fight, which was one of the fiercest since the founder of their town (Achebe 7). Okonkwo was a tough, young man and was afraid to show any weakness. Okonkwo drew his machete and cut him down. He was afraid of being caught weak (Achebe 59). Okonkwo killed Ikemefuna before the other man could because he was taking too long and he wanted his people to think he was fearless for being the first to kill him. The tragic hero of a story must exhibit wisdom or be noble at birth. Unoka, Okonkwos father, was lazy and improvident and was quite incapable of thinking about tomorrow (Achebe 8). He resented his fathers failure and weakness; resented means that Okonkwo was angry and embarrassed of his fathers laziness. Ever since he was young, he wanted to be the opposite of his father. Okonkwo was ruled by one passion- to hate everything that his father Unoka had loved (Achebe 17). Okonkwo is a great leader of his tribe. Many people looked up to him because he is so intimidating to others. While exiled into his motherland, the church and their religion began to take control over all of the tribes. Okonkwos own son, Nwoye, turned to the church. He became fascinated with the poetry. Okonkwo declared a war against them but most of the people in his clan turned to the church. He finally leads the rest of his clan to go burn down the church. This example shows he is a great leader and sticks to his own beliefs, therefore he is a tragic hero (Dictionary.com). The last rule of a tragic hero is that the main character suffers a reversal of fortune because of their flaw. Okonkwo, with his flaw of anger and violence, got out of control one day; he decided to take control, with or without his clan, and kill one of the three church messengers. The villagers, all in shocked and speechless let the other two messengers go. The district commissioner goes to Okonkwos obi so he can take him to jail, but Okonkwo had already hanged himself because he wanted everyone to see how dedicated he was to his clan and know how much the church had separated them all. This flaw of overconfidence of getting his clan back to the way it was reversed his fortune and now he cannot do anything more to help them. In conclusion, a tragic hero would be one who involves the notion that such a hero would make an error in their actions that leads to his or her downfall. This tragic hero must be a character with flaws but with some goodness, which brings them down in the end. They are typically hubris, which is ones own self-confidence and excessive pride. They are the protagonist of the story and they are noble at birth. The final rule for being a tragic hero suffers a reversal of fortune because of their tragic flaw (Wikipedia.com).

The Baby Boom

The Baby Boom was one of the most important events in Canadian history and continues to Impact how we live our lives today. After World War 2 ended, between the years of 1945 and 1 965, there was a huge increase in population known as the Baby Boom. The Baby Boom occurred because soldiers came home from war with a victory and were flnally ready to start a family with their wives or girlfriends In a time when there was a good economy. In 1959, 20 percent of all women who were in their twenties had babies and the average family had three to four children (1 ).Around 1961, births per 1000 women aged 15-49 hit almost 4,000 (5). In total, more than 8. 2 babies had been born during the baby boom in Canada (2). These statistics give you an indication about how densely and quickly the population increased and how this bulge in the population could not be Ignored through the years, Many events In history have helped shape Canada into the country it is today, but nothing has made such an impac t on how we have lived, live now, and will continue to live as much as the baby boom has.The Baby Boom created an overwhelming demand for homes ecause of expanding families needing more room for their newborn children, this demand led to something called â€Å"Suburbia†. More than 1. 1 million housing units were bullt In the 1950's (3) to adjust to all of the new families who needed homes – this began the first decade of â€Å"urban sprawl†. There would also be a big huge demand for nurses, school teachers, doctors and such to take care of the huge amount of new kids born as a result of the Baby Boom.CanadaS economy had gone from making Bren Machine Guns Just a few years earlier for the war to making baby arriages, baby clothes, new cars, and bunk beds for all the new children that had lust recently entered Into the world. A few years later. during the 1950S, when the â€Å"baby boomers† started to become teenagers, society had to adjust accordingly as we ll. Many communities began to build new arenas, recreational facilities, organizations, and â€Å"teenager hangouts† in order to make up for the huge amount of adolescents roaming their society. In the same time period the baby boomers also began to greatly influence music culture and such.Teenagers tended to listen to the ig rock and roll stars at the time, Including Chuck Berry, Elvis Presley and Ottawa's very own Paul Anka (4). Marketers began to realize that the more they used these songs, the more money they would make. That being said, the baby boomers virtually catered to not only the music Industry, but things such as film and books as well. The baby boomers were controlling the way the 50's and 60's would later be viewed and talked about in the future. The Baby Boomers are affecting todays communities. The average baby boomer would be around 65 years old this year.Today, they don't ecessarily rule the media world, but they do have a huge impact on Job openings for yo ung people. The baby boomers are occupying all of the big Jobs of today, making it harder for younger people to find Jobs that pay well to support their families. Luckily for teenagers of today, soon the baby boomers will be retiring all at once, leaving a huge amount of Job openings in their path. Once the baby boomers retire and Decome seniors, tne taxes may De Torcea to Increase In order to cater to tne needs 0T the huge amount of elderly and their requirements, such as government pensions, nd Medicare.There might also be smaller changes that the average person wouldn't notice, such as the demand for soccer fields and hockey arenas may decrease and golf courses could become more popular. If the Baby Boom from 1945- 1965 didn't happen, the world today, leading up to today, and even the future, would be very different from the way we live now. When the baby boomers were originally born, they required a huge amount of new housing and supplies, as well as causing a vast increase in p opulation in a very short period of time.When the baby boomers grew up to be teenagers, they virtually controlled the media scene and also required a lot of new buildings and things to be built. Even now, when they are almost seniors in our society, they control a lot of things, one of the bigger things being employment. The Baby Boom happened around 55 years ago, and it still is showing impact on Canada's development today. There are many other events in Canada's history that contributed to Canada's development but nothing continues to have as much of a significant impact as the Baby Boom does.

Character and Point of View in “The Red Convertible” Essay

â€Å"The Red Convertible† is a short story by Louis Erdrich, in which two native American brothers named Marty and Henry decide to buy a red convertible Oldsmobile together. The two brothers spend much of the summer travelling around together in the car until the older brother, Stephan, is deployed to Vietnam. When Stephan returns, he is not the same and Marty tries desperately to recover their past relationship. The round, static, perseverant character of Marty in â€Å"The Red Convertible† is revealed through the first person point of view. The younger brother in the story, Marty, is round and static. Throughout the entire story, the reader is given insight into Marty’s thoughts and feelings, such as, â€Å"I was sorry I’d ever bought it, though, because of Stephan, and I was also sorry I’d bought color† (Erdrich 5). Marty does not openly convey this statement to his family. Marty’s beliefs and values do not change over the course of the story. In the beginning he, â€Å"thought back to times we’d sat still for whole afternoons† (5) and in the end of the story he yells at Stephan, â€Å"wake up, wake up, wake up!† (8). This shows that at the end of the story, Marty wants things to be normal just like he did in the beginning of the story. Marty’s perseverant nature influences the story because it shows how deeply he longs for his relationship with his brother to be normal again, and creates a sense of desperation. For example, Marty says, â€Å"One night Stephan was off somewhere. I took myself a hammer. I went out to that car and I did a number to its underside. Whacked it up† (6). This shows how much he is willing to do to make Stephan normal again despite Stephan’s serious condition. Also, when Marty says, â€Å"By the time I get out of the river, off the snag I pulled myself onto, the sun is down† it is implied that he tried to save Stephan from drowning, again showing how desperate Marty is to have his brother back. The point of view of the story is first. The author repeatedly uses statements like â€Å"I’m laughing so hard† (10) and, â€Å"I walk back to the car† (10). This makes it clear that the story is being told from Marty’s point of  view. The effect of using a first person point of view in the story is allowing the reader to have an emotional connection with Marty because it puts the reader in his shoes. The story may not be effective if told from another point of view such as third dramatic because the reader would not be able to fully understand the depth of Marty’s connection with his brother because his feelings would not be expressed in the story. The round, static, perseverant character of Marty is revealed through the first person point of view. Because the story is told from Marty’s perspective, it reveals how desperately he wants Stephan to get better. For example, Marty says â€Å"I tell you right then I wanted to smash that tube to pieces† (5). This shows how he was ready to destroy something he worked hard for in hopes it will help to make his brother better. Throughout the story Marty continues to do things to try to make Stephan better and through the first person point of view the reader sees how often he hopes and tries to accomplish this. By the authors use of the first person point of view, it allows the reader to be put into Marty’s shoes, therefore developing a round, static character and reveals to the reader how perseverant Marty was due to his relationship with his brother.
