Evenin Air Blues

The poem Evenin’ Air Blues written by Langston Hughes was published in 1951. The poem consists of four six line stanzas or sestets. In the poem, a poor black man, who is probably an escaped slave, in a sad tone, speaks about the mismatch between the picture of Northern American states that existed among the Southern slaves and the reality in which although there is no slavery, living conditions are hard, and people can hardly makes their ends meet.Advertising We will write a custom essay sample on Evenin’ Air Blues specifically for you for only $16.05 $11/page Learn More The first stanza of Evenin’ Air Blues is a sestet, and the rhyme scheme is â€Å"ababcb†. The rhyming words are â€Å"North†, â€Å"fine†, â€Å"months† and â€Å"mind†. The first two words are repeated two times each. He chose those particular words to emphasize the basic introductory information which is the location – Nort h, its alleged description – fine, the amount of time he spent there – months, and the effect it had on him – that he almost lost his mind. Some critics have pointed out that rhyming â€Å"fine† and â€Å"minds† is technically a really bad move, and that it takes away much of the poems quality (Tracy, 158). Repetition as a tool is used here to show how rumors about the life in the North are repeated almost like a mantra among the Southern slaves. The second stanza of the poem also consists of six lines with the rhyme scheme is â€Å"efefgf†. The words that carry the rhyme are â€Å"breakfast†, â€Å"air†, â€Å"supper† and â€Å"spare†, the first two of which are used twice. The most prominent words that carry the rhyme are related to food – â€Å"breakfast† and â€Å"supper†, and they are used alongside the word â€Å"air† which is associated with emptiness and void. By doing this, the poet achieves his goal of vividly describing the day-by-day struggle that all of the black people faced. The main tool here is literal image. Hughes uses it very effectively so the reader can almost feel his long days without food and shelter. The physical repetition of words parallels the sameness of days in his life. That way, we get the picture of the lack of basic existential necessities that the speaker faces. In the third stanza, we get somewhat different but simple rhyme scheme – â€Å"hjhjhj†, but the number of lines is the same as in the first two. The rhyming words in this stanza are â€Å"dancin’†, â€Å"away†, â€Å"stay†, and the first two are, again, repeated two times. The word â€Å"dancin’† is chosen and repeated to transfer the atmosphere of dance nights; â€Å"away† is used in order to show the effect dance has on his sadness, and â€Å"stay† is used to emphasize the permanence of his melanchol y only occasionally interrupted by dances. In this stanza, the reader is introduced to the idea of dance as an antidote to poverty and suffering in a big city. The main tool in this stanza is personification, which is apparent in the last line, when the poet says how â€Å"blues forgets to stay†. In my view, by using this tool, the poet wants to emphasize how the speaker feels the blues as a conscious force or a spirit because of its power over him. This stanza shows us that artistic expression is what keeps people sane and gives them power to endure the hardships they face.Advertising Looking for essay on american literature?

In this stanza, the words that carry the rhyme are â€Å"me†, which is repeated three times, â€Å"beâ⠂¬  repeated two times and â€Å"see†. â€Å"Me† and â€Å"be† are used in an altering way to indicate how the speaker’s person is the permanent dwelling of the blues. The word â€Å"see† is used almost as a call for the reader to notice how apparent the cause of his sadness is. As for the number of lines, this stanza conforms to the rest of the poem, which means that it has six lines. The main tool which is used here very effectively is internal rhyme, and it can be found in the last line where the poet rhymes â€Å"me† and â€Å"see† line internally. The poet uses the opportunity to repeat the word â€Å"me† for the fourth time in this stanza almost as a way of physically pointing at himself to draw the attention of the society at his conditions. This effect is made even stronger since the word is rhymed with the verb â€Å"see†, which calls for people’s attention almost like an imperative. In conclusion, one m ight say that although criticized for its technical issues like problematic rhyme in â€Å"fine – mind† and dialectal inconsistencies, this poem is very valuable because it provides a vivid picture of disappointment in the life in the North. It is also worth adding that the poet has succeeded in transferring the lives of ordinary, poor, black people into artistic expression, and at the same time, he preserved the tone and atmosphere of everyday life by using the colloquial Southern dialect.

Clean Air Act essays

Clean Air Act essays Pollution in the United States is getting worse and worse by the day. Poor air quality is a serious issue and health risk in cities throughout the country. The main source of the pollution problem is our transportation. Cars produce roughly one half of the pollution in our cities, and about a quarter of the greenhouse gases. The internal combustion engine is the single largest source of air pollution in the United States. Toxic gases are emitted into the atmosphere as byproducts of the combustion process and also from evaporating gasoline. The main pollutants consist of carbon monoxide, nitrogen dioxide, hydrocarbons, and particulates, each of which are harmful to the human body and contribute to global warming. Carbon monoxide is the largest pollutant emitted. It attaches to the hemoglobin in the blood and lowers the bloods oxygen-carrying capacity, which causes headaches, drowsiness and blurred vision, and is fatal with prolonged exposure. Hydrocarbons cause eye irritation, coughing, wheezing, shortage of breath and serious lung damage. Nitrogen oxide causes acid rain and taints the quality of our water. Pollution is obviously a very serious problem that is putting each of us risk, as well as damaging our environment. Unfortunately this is not something that can be solved any time soon, however we must make an effort to deal with it. Gasoline is not the only way to power an automobile. There is technology out on the market, along with much more still in development, that provides logical substitutes to our current automobile fuel. Several companies have started mass production of cars that are fueled by both electricity and gasoline, known as hybrids. These hybrids only use gasoline during acceleration and run off an electric battery the remainder of the time. This allows these cars to travel up to 70 miles on one gallon of gas and they are still able to move at speeds ne ...

Diabete Essay Example | Topics and Well Written Essays - 1000 words

Diabete - Essay Example The patient is drowsy and the pulse rate is counted as 110. The respiration is fast at 25 deep and sighing breaths per minute, acetone on breath and keto-acidosis has been made. Type I diabetes can occur in patients of any age and is characterised by the inability of the pancreas to secrete the hormone insulin due to autoimmune destruction of the beta cells. It occurs in children quite abruptly, though new antibody tests have been developed to detect new onset adult form of type I diabetes mellitus known as LADA (latent Auto-immune Diabetes of Adults). What distinguishes them from other diabetic patients is the fact that if insulin is withdrawn, they develop ketosis and eventually ketoacidosis. Hence such patients are always dependent on exogenous insulin. Many of the pathophysiological disturbances in a patient with DKA can be measured by a clinician and should be monitored on a real-time basis throughout the course of the treatment. Attention to clinical laboratory data can help the clinician to track and prevent the onset of secondary lethal complications such as hypoglycemia and hyponatremia and hypokalemia. In the absence of insulin, the primary anabolic hormone, muscles and fats as well as the liver do not take up glucose. Counter regulatory hormones such as glucagons, GH and catecholamines enhance triglyceride breakdown into free fatty acids and gluconeogenesis causing an upshot in the level of serum glucose levels in DKA while there is no insulin. Betaoxidation of these free fatty acids then lead to increased ketone body formations. Metabolism in DKA shifts from the normal fed state to the fasting state characterised by fat metabolism. Secondary complications of primary metabolic derangement include an ensuing metabolic acidosis as ketone bodies deplete extra-cellular and cellular acid buffers. The hyperglycaemia induced osmotic diuresis depletes phosphates, potassium, sodium and water together with glucose and ketones. Most commonly, it depletes 10% of body water and 5mEq per kg of body mass of potassium. The total body potassium may be masked by acidosis by sustaining an increased serum potassium level. The levels can fall precipitously once the rehydration and insulin treatments start. Loss of ketoanions in urine with brisk diuresis and intact renal function may also lead to hyperchloremic metabolic acidosis. Frequency In the USA, DKA is seen in patients with type I diabetes. The incidence is grossly 2% patient years of diabetes and almost 3% of diabetes patients initially presenting with DKA. It can occur in type 2 diabetic patients as well though not as a rule. The mortality rate of DKA is nearly 2% per episode. Before the discovery of insulin in 1922, the mortality rate was almost 100 percent. Though patients less than 19 years of age are more prone to DKA, it can occur to a person of any age. History of patients and symptoms at presentation. Clinicians should look out for the classical symptoms of hyperglycemia such as thirst, polyuria, polydispisia and nocturia. Other symptoms include: Generalised weakness Lethargy Nausea Fatigue Decreased perspiration Confusion Increased appetite and Anorexia Clinicians should also be on the
