Free Essays on Sickle Cell Anemia

There have been many researches and tests done on the genetic causes of Sickle Cell Anemia and how it developes, as well as it’s effects on the circulatory, muscular, and respiratory systems, as well as it’s effects on the joints and other systems of the body, and the complications associated with them. Most of the research has been done to explore on the reasons why it mostly effects the African-American community and people who are from the West Coast of Africa. It has also been known that Sickle Cell Anemia also effects people from the Mediterranean countries (Wethers, 2000) Sickle Cell Anemia is a the most common single gene disorder found mostly among Black Americans (Wethers, 2000). According to scientific research, it affects approximately one in 375 persons of African ancestry. According to one researcher, â€Å"Sickle Cell conditions are also found to be in persons from Mediterranean countries also, such as Turkey, the Arabian peninsula, and the Indian subcontinent†( Wethers, 2000, p.1014). Extensive research has also proved that Spanish speaking persons in the United States, plus people from the Caribbean and South and Central America, are also effected by Sickle Cell Anemia (Wethers, 2000) The first case of Sickle Cell Anemia was first published in 1910 by scientists, and has since then been followed by at least six decades of many observations, which include genetic, molecular, and pathologic observations (Wethers, 2000) Large bodies of clinical data has on the evolution of Sickle Cell Anemia from birth has been gathered on studies of children since the 1970’s (Wethers, 2000) The United States has studied 3,500 patients Page 2 with the Sickle Cell disease, and based on these studies, the longevity and quality of life of these patients have greatly improved (Wethers, 2000).

Free Essays on Sickle Cell Anemia Free Essays on Sickle Cell Anemia Sickle cell anemia is an autonomic recessive disorder in which abnormal hemoglobin leads to chronic hemolytic anemia along with periodic episodes of pain. The mutation in hemoglobin sickle cell anemia is a blood condition primarily affecting people of African ancestry. It has been researched and proven that the error in the hemoglobin gene results from a genetic mutation that occurred many thousands of years ago in people in parts of Africa, the Mediterranean basin, the Middle East, and India. It is associated with being immune to malaria, a parasitic blood disease that is carried and contracted by infected mosquitoes. Since malaria is mostly found in hot, moist areas in West Africa and the Mediterranean, people originating from that area produced an immunity to towards malaria, but with consequences (Bloom). The individual will not contract malaria because the mutation in his/her genes quickly fight off the disease by changing the shape and composition make-up of the blood cell so the parasites will not be able to survive in it (Van Cleve, Lemerond). The consequence of this is that because the individual’s blood cells mutate and become misshaped, becoming â€Å"moon crescent† or â€Å"sickle-shaped†, the blood cells then grows and becomes to big to pass through most blood vessels, mostly capillaries and veins, which causes it to form a clumped together mass. The blood vessel where this happens is mostly associated with the joints and the lungs. Unlike normal red blood cells, which last about 120 days in the bloodstream, sickled red cells die after only about 10 to 20 days. Because they cannot be replaced fast enough, the blood is chronically short of red blood cells, a condition called anemia. When this happens, the child or adult experiences great amounts of pain, making it almost impossible for them to ambulate. The joints get swollen and red. Another condition is that the clump of misshaped blood cells still can travel ...

Unexpected Places To Find Jobs

Unexpected Places To Find Jobs You’re on the job search, so you’ve been hitting up your network and going through online job postings. But you won’t have exhausted all your options unless you’ve tried following these 7 bonus leads. Check out the following 7 unexpected places to find your jobs. 1. Your former bossProvided you parted amicably and you did good work for them, it’s actually a smart move to track down all your old bosses to see what they have to say. (If you burned a bridge, it might even be worth trying to patch it back up now that you’ve both cooled off and you’ve matured?) Maybe they won’t have a job for you, but they might very well have a lead. And they might even be willing to put in a good word.2. Former co-workersIf you haven’t already added all your former coworkers to your network, now’s a good opportunity to fix that. Connect with anyone you worked with directly, plus anyone in other departments or divisions with whom you m ight have had contact. If you don’t know where to find them, try LinkedIn. They might be able to help you out- and you could help them in the future too.3. Companies that didn’t hire youWait, what? No really. If you had a really positive interview process somewhere and didn’t ultimately end up getting the job, but were told to keep in touch- or even just that it was a really tough call and you shouldn’t be discouraged by not getting the job- get in touch now! They’ll appreciate the initiative. And even if they don’t have any openings, they might be willing to point you in the right direction.4. YouTubeThis is less to find a lead and more to get yourself out there so the leads will come to you! Make a video version of your resume and post it to YouTube- or demonstrate a particularly expert skill of yours. Make sure it’s of the highest quality and super professional before putting it online.5. NewspapersIt’s a little bit old-fash ioned, but some companies do put listings in the paper and few job seekers still look for them there. It’s always worth a shot. And while you’re at it, make sure to keep up on all the latest news and business trends relevant to your field. When you do find a lead, you’ll be in a much better position to land the job if you’re up to snuff on what’s going on in your industry and in the world.6. Alumni networksNo matter where you went to school, if you have an alumni organization you haven’t been taking advantage of, now’s the time to change that. Go to alumni group meetings in your city. You never know who you’ll meet. And, bonus! You already have something in common as a conversation starter.7. A career coachYou’ll have to pay for this, but the benefits could far outweigh the cost. Get an expert in your field to help evaluate your eligibility and performance and help steer you through the job search process in your field.7 Unexpected Sources For Job Leads

London Olympics 2012 - Essay Example This essay throws light on Olympics 2012, the history of Olympics, about London and the impact of this event on major stake holders in the host community. The researcher states that Olympic Games are one of the biggest international events. It features both summer and winter sports in which thousands of athletes participate in a variety of competitions. The games are held in every two years on even numbered years only. Summer and Winter Olympic games, alternate every next year which means that the seasonal games are held every four years. The 2012 Summer Olympics were held in London, that is England’s capital city. London was elected to be the host city for Olympics 2012 on 6th July 2005. Their rival competitors were Moscow, New York City, Madrid and Paris. At least 4 voting rounds took place. London was headed by the former Olympic Champion, Sebastian Coe. It is stated that London is a metropolitan city and is claimed to be the largest city of Britain, its history dates back to the Roman Empire. In the past it has hosted Olympics twice. Over the last couple of years, the scale and scope of the Games has grown enormously. It is now represented by every nation on the block.

Compare and contract the views of society presented in Equus and the Essay

Compare and contract the views of society presented in Equus and the time machine - Essay Example This will be illustrated by excerpts from H. G. Wells’ The Time Machine and Peter Shaffer’s Equus. This essay will focus on two aspects of social conformity namely; normalcy and entropy. The works of both writers portray a vision of a troubled future if man continues to dwell within the societal confines that propagate passivity while ignoring pressing issues such as social class splits and individual passion. Normalcy refers to what the society considers the right aspects of behavior. Passivity means inactive or submission to the will of others. In Equus, Dysart is considered normal as he rarely strays outside of societal boundaries. He is married, has no children, and has a good education and profession that places him in a high social class. However, he feels that his life is dull with no spiritual communication. His marriage lacks intimacy as illustrated by his admission that he has not kissed his wife for six years. Disillusioned with modern civilization and unhapp y with his role in it, he turns to Greek civilization for spiritual comfort. This highlights the internal conflict that most people have. In conforming to society’s belief of what is considered normal, one loses their individualism and passion, causing misery in their lives. In contrast, his patient, Alan, seems full of passion and vigor. Alan goes against the societal indoctrination to conceive the idea of a god that differs from the traditional Christianity. This is propagated by the conflicting views on religion of his parents. His mother is a staunch Christian who read him the bible daily and taught him that the sexual act was dirty. His father was an atheist and a strict disciplinarian that could not even allow him to watch television because he believes that it takes away one’s intelligence and concentration. Both parents are products of social norm, which requires them to exist in a world without passion and worship. As a result, Alan conceives a horse god, Equu s, with which he freely expresses his passionate worship and sexuality. He compares the horsegod to Jesus when he says, â€Å"I see you, I will save you.† (66). This adoration hits its climax when he blinds six horses. As a result, he is declared unbalanced and in pain and sent to Dysart to heal his mind. This violence brings out the conflict between the two myths: the pagan worship he created, and the Christian one he inherited which saddled him with guilt and shame concerning his sexuality. The eyes are symbolic of society’s checks on its members, constantly judging and punishing. By striking the eyes, Alan fights the society that has oppressed him. Thus, society forces blind obedience and individuals are forced to suppress their desires. Even though most people are aware of this consequence and are dissatisfied with their miserable existence, they lack the commitment to change their lives. Dysart feels that by removing one’s uniqueness he is destroying part o f their personality, but ultimately strips Alan of what he desires most. Normalcy and passivity are also evident in The Time Machine. The social disparity between the leisurely wealthy upper class and the working class was considered normal, especially in the Victorian England. The rich exploited the workers for profits to finance their passive lifestyle as portrayed by the laziness in the dinner guests in chapter one, who meet to dine and chat. The time traveler belongs to the upper class. This passivity is also evident among the Eloi (upper

The Importance of Military Ethics in War Essay -- War, Army, marine, I

Military Ethics War has always been, and will always be, a necessary action perpetrated by the human race. There are many different reasons for war: rage, passion, greed, defense, and religion to name a few. When differences cannot be solved or compromised through mediation with an opposing party and anger burns with a fiery passion, war is the last remaining option. Obviously, the purpose of any war is to win. How are wars won? Perhaps if we were to ask a member of the Defense Department during the early stages of the war in Iraq, his answer might be, â€Å"To win this war we must force the enemy into submission by means of ethical warfare.† If we were to ask a marine in the Second World War what he was told by his commanding officer he would reply, â€Å"To close with the enemy and destroy him.† (Fussell, 763). The member of the Defense Department and the marine have a common goal; to win the war. But there is a difference in their mindsets. The politician, safe behind his desk, has never experienced the fear and terror of being in battle. He has not seen the blood or heard the screams of suffering soldiers. He has not watched his best friend die in his arms after being hit my enemy fire. He is an onlooker, free to analyze and critique every aspect of the war from the safety of his office. He is free and safe to talk of ethics and proper war etiquette. The marine, immersed in battle, fighting for his life, can think of only one thing. Kill or be killed. When bullets are flying past his face and mortar shells are exploding all around him, he is not mindful of fighting ethically. Nor is he even mindful of fighting for his country. He is fighting for his life. To stay alive, he must kill the enemy, destroy the enemy. ... ...Ultimately, the way in which every war is won is by killing the enemy. That will never change. But the way in which an army goes about killing the enemy will constantly change due to ethics, new technology, new levels of hatred, and so on. There are always protesters to every war: â€Å"Stop the war! No more killing! Peace on earth!† Who doesn’t want these things? Do they think that the soldiers fighting for our country want to experience the horrors of war? Of course not, but if we do learn anything from history, it is that the human race will never stop waging wars on each other. People will inevitably die at the hands of war and the best that we can do is protect our troops at all costs, destroy the enemy, and spare as many civilian casualties as possible. I agree with General W.T. Sherman who said, â€Å"War is cruelty, and you cannot refine it.† (Fussell, 774.)

Write a Brief Description of the Fiscal Policy of the United States.

2–3 paragraphs Details: During recent political campaigns, taxes and budget policy were key issues. White House budget packages are often designed to stimulate economic growth. From the library or from www. whitehouse. gov, obtain a current summary of government spending and tax legislation signed by the president. †¢Write a brief description of the fiscal policy of the United States. †¢Would you describe it as â€Å"expansionary† or â€Å"contractionary†? †¢How can American consumers influence decision makers on fiscal policies? Explain and discuss if and how this has changed over the past 5 years For the last several years, the U. S. government has been primarily in an expansionary mode of fiscal policy. President George W. Bush signed a $152 billion stimulus bill to help fight off a recession. This bill primarily resulted in the mailing of $600 rebate checks to millions of Americans to encourage consumer spending. In 2009, President Barack Obama signed the much larger American Recovery and Reinvestment Act, which provided tax cuts, loans and contracts, and new or expanded entitlements. The Congressional Budget Office estimated that the legislation would increase the U. S. budget deficit over a 10 year period by $787 billion. According to www. whitehouse. gov, this legislation created or maintained almost 700,000 jobs in the first quarter of 2010. The main way consumers influence fiscal policy is by their spending habits. When citizens become anxious about the economy, they tend to save more and spend less. This leads to decreased production, lay-offs, and unemployment, which in turn causes even lower spending rates. The Federal reserve usually tries to modulate the effects of these situations by manipulating key interest rates. For example, right now the federal funds rate is at a 60-year low, making borrowing for investments cheaper than it has been in memory. Until recently, consumer spending saw long-term increases due to the availability of personal credit, but since 2008, as consumer credit markets have tightened, it has dropped.
