Analysts are still studying whether the two strips of cloth called gap filler that are poking out from the bottom of the orbiter could cause uneven heating during re-entry that may constitute a threat to the craft and crew, the mission's lead flight director, Paul Hill, said in a press briefing this morning. If the analysts decide that the gap fillers do pose a threat, he said, the mission manager may call for a risky spacewalk and repair maneuver in which astronauts try to pull the tough material the rest of the way out, push it in or cut it off. Mr. Hill said a spacewalk repair was not likely but that his engineers and analysts were looking closely at the issue and that he could not rule one out. Gap fillers, as their name implies, fill the gaps that NASA leaves between some shuttle tiles to allow for expansion and contraction of the shuttle's body from the extremes of heat and cold that it is exposed to. The fillers themselves are heat resistant, and are made of alumina-borosilicate fiber. Having gap filler poke its way out up from between tiles is not uncommon, but it could be a concern because it causes an uneven surface and can lead to unusual patterns of heating during re-entry. If a filler pokes out too much, especially if it is far forward on the shuttle so that its downstream heating affects a larger part of the shuttle's belly, it could be a problem, Mr. Hill said. NASA, through a long examination of all previous landings with protruding bits of gap filler, had found a comfort level with protrusions in the same areas that stick out a quarter of an inch, he said. But the two pieces on this flight are one inch and six-tenths of an inch, he said. This shuttle and the space station have been outfitted with more cameras and sensors than ever before, and so they might be detecting something that has happened many times in the past; it is possible that the feltlike material burns down during re-entry, and that longer protrusions have occurred in the past. But one quarter inch is within "our conventional wisdom," Mr. Hill said, and so the little strips of cloth have become an intense focus of aerodynamic analysis, he said. Aerodynamics experts have been studying the size and the position of the two gap filler protrusions, Mr.

Diarrhea

Diarrhea is abnormally frequent and watery bowel movements. It is one of the most common bodily disturbances. Diarrhea may be a mild symptom of some more serious condition, such as tumor of the bowel (intestine), or may be the chief symptom of an infection in the bowel caused by bacteria, viruses, or parasites. In addition, diarrhea may be caused by improperly prepared or spoiled foods, by contaminated water, by certain chemicals, by irritation or inflammation of the lining of the intestines, or be generalized diseases that do no involve the bowel primarily (Stone, et al.112-113).Diarrhea varies from a slight inconvenience lasting a day or two to a grave illness. The most severe form of diarrhea is found in persons suffering from cholera. Consequences of diarrhea are loss of electrolytes, such as sodium and potassium; dehydration; and, in severe cases, heart failure. Diarrhea is a leading cause of death in infants. Treatment of diarrhea is directed towards eliminating the cause, when the cause is known. Drugs such as paregoric may be used to decrease the irritability of the bowel.The patient may be given extra fluid, injected directly into his veins (Wolfe 34-36), to make up for fluids lost through the bowel. Furthermore, diseases of the digestive system are essentially of two types, infections and intoxications. An infection occurs when a pathogen enters the gastrointestinal (GI) tract and multiplies. Microorganisms can penetrate into the intestinal mucosa and grow there or can pass through to other systematic organs.Infections are characterized by a delay in the appearance of gastrointestinal disturbance while the pathogen increases in numbers or effects invaded tissue (Wolfe 34-36). There is also usually a fever, one of the body’s general responses to an infective organism. Some pathogens cause disease by elaborating toxins that affect the GI tract. Intoxication is caused by ingestions o such a performed toxin. Most intoxications, such as that caused by Staphylococcus aureus, are characterized by a very sudden appearance (usually in only a few hours) of symptoms of a GI disturbance.Fever is less often one of the symptoms (Stone, et al. 112-113). Both infections and intoxications often cause diarrhea, which most of us have experienced. Severe diarrhea, accompanied by blood or mucus, is called dysentery. Both types of digestive system diseases are also frequently accompanied by abdominal cramps, nausea, and vomiting (see http://digestive-disorders. health-cares. net/diarrhea. php). The general term gastroenteritis is applied to diseases causing inflammation of the stomach and intestinal mucosa (Stone, et al.112-113).Botulism is a special case of intoxication because the ingestion of the performed toxin affects the nervous system rather than the GI tract. In the developing countries, diarrhea is a major factor in infant mortality. Approximately one in every ten children dies of it before the age of five. It also affects the absorpt ion of nutrients from their food and adversely affects the growth of the survivors. The cause of diarrhea may be any of several organisms.Most are not identified, but surveys in such countries as Bangladesh indicate that the three most common causes are enterotoxigenic E. coli, Shigella spp. , and intestinal rotaviruses. It is estimated that mortality from childhood diarrhea could be halved by oral rehydration therapy (Stone, et al. 112-113). Ideally, this is a solution of sodium chloride, potassium chloride, and sodium bicarbonate. However, even a solution of a handful of table sugar and a pinch of salt in a liter of water has proved to be a very useful treatment for diarrheal diseases. Reference: What is diarrhea?

Death of a Salesman Tragic Hero

Willy as Tragic Hero in Death Of A Salesman Willy Loman is indeed a pathetic and tragic hero of Death of a Salesman. His problems stem from his own delusions, the American Dream turning sour, and misunderstanding his job and family. All of this tells the story of everyday people in American society. His environment is changing faster than his beliefs which is why he is in the dilemma that he is in now. His own delusions are a result of his failure to succeed in life. He still believes he is popular, respected and good looking. But at age 63, he is none of these. Nobody liked him that much since very few people came to his funeral.His delusion was that there would be people across the country coming to the funeral. However, in those moments that he begins to realize the truth, his wife Linda while understanding his situation, supports his delusion. She say to him that â€Å"you're the best looking man in the world†. But the truth is that being popular and good looking is not ho w you would succeed in the world now. It would be through hard work and perseverance. The American Dream has long turned sour for him. At the beginning of his life, he remembers traveling in a wagon going westward. His parents conquered the new frontier and succeeded.His brother Ben went â€Å"into the jungle at 17 and came out rich at age 21†. For a while, the American Dream was alive in Willy too. He helped stake out new territory by selling his goods, his son Biff was going to go to university with a scholarship and he had a home with no apartments closing on him. But now, he was forced to work on commission at an old age and was fired later by his godson. His favored son Biff had wandered about the country doing odd jobs for many years, his friend's son Charlie was successful and his home was now surrounded by apartment buildings which blocked out the sunlight.He was not a success in selling , he failed to raise his sons and his beliefs were just delusions. Only through h ard work and perseverance would he achieve his goal of success but he decided to go along the lazy route and failed. Willy Loman misunderstood his family and job with profound reprucssions. He totally misunderstood his occupation by trying to sell himself than the products. He could not hope to succeed because there was virtually nothing to advance on him. People could buy into him because there was nothing to sell in the first place. Because of t his, he eventually lost his job.His family was something he equally misunderstood. His wife and two children did not let him know that they knew the truth about him. They would tell him t hat his beliefs were wrong and that they knew he was trying to kill himself. They did n ot always support him. As Biff was leaving the restaurant, he told Happy to take care of his father. Happy rejected him and he told the 2 girls he had picked up that Willy was not his father but was â€Å"just a guy†. Willy left the restaurant very humiliated. H is son Biff no longer had the same ideals as Willy or respected him much after his affair with Miss Francis.He had instilled the idea along with Linda that they had the ability to save him but they didn't. He later dies to escape the repercussions of the problems he has caused himself. The pathetic and tragic hero of Death of Salesman is Willy Loman. He had a bright future but later got lost along the way. This is the story of the â€Å"Low Man†. Many believe in ideals like Willy's, many have had the American Dream fail and many did not see that their family lost their way because of them. It is a tragedy that a man with so much potential lost everything by believing in the wrong things and never realizes his situation.

buy custom The Media essay

buy custom The Media essay Through the advertisements by different kinds of media, people are bombarded. From the huge layouts in the newspapers and magazines to thirty second spots on television to sexy echoing advertisements on billboards up and down the main roads to radio, people ca not help but see the marketing and absorb them into their minds. The advertisements rarely contribute a part in shaping peoples interests and dislikes. People tend to create opinions that are normally based orally from other people or from the advertisements they see daily even if they have not attempted to use the products. Mayer (74) suggests that people obviously buy perfumes that they come to find out through the media advertisements because they liked the scent. The mass media in all categories direct unsuspicious consumers through networks of inforation and anticipations. The mass media controls what consumers view, how they see it and when to see it. Sellers spend huge cash on market research and aware of who to aim at with definite advertisements. They also establish when their target spectators or viewers are mostly likely watching television as well as the certain shows by the use of demographics. When it comes to perfume advertisement and market, the famous persons are a big draw. This is because at times the celebrity or the public figure of a celebrity represents what the perfume manufacturers want to describe to the public or the society (Paul 30). In that case if the perfume is produced with teenagers in mind and a smell is a light flowery, the celebrity presenter is likely to be someone that the teenage demographic will recount to. This may include a famous actress in youngster movies, ann athlete or even a singer that many people look up to or recognize. The liking and disliking of the perfume by someone hugely relies on the olfactory senses clearly. Memory however largely determines the scents or smell. Individuals memories play an influential fraction when it comes to selecting a new perfume may be it is because roses bring back a cheerful day in grandmothers garden or a clean linen aroma takes you back to a calm time in a country cottage (Roy 84). However, when the media (magazine) participates in the perfume or fragrance advertising and marketing, they will have played their role if their advertisements got people as far as the branches of stores or anywhere that their perfumes are sold (Diane 222). Once consumers reach the stores the control is in their hands. Buy custom The Media essay

Funny Quotes to Celebrate the New Year

Funny Quotes to Celebrate the New Year Every New Year brings a chance to mark the passage of time, reflect on the past, and embrace the future. Some of us celebrate the occasion by partying into the wee hours of the morning; others struggle to stay awake to watch the clock hands move past twelve. We make resolutions, only to break them; we promise to do better, try harder, be better, but oftentimes fall short as life gets in the way. The humorous quotes below, though, will help you start the New Year smiling. Mark Twain New Years is a harmless annual institution, of no particular use to anybody save as a scapegoat for promiscuous drunks, and friendly calls and humbug resolutions. New Years Day now is the accepted time to make your regular annual good resolutions. Next week you can begin paving hell with them as usual. Brooks Atkinson Drop the last year into the silent limbo of the past. Let it go, for it was imperfect, and thank God that it can go. Bill Vaughan Youth is when youre allowed to stay up late on New Years Eve. Middle age is when youre forced to. An optimist stays up until midnight to see the New Year in.

2nd Amendment (Right to Bear Arms) Research Paper

2nd Amendment (Right to Bear Arms) - Research Paper Example The Court ruling also says that an individual can use firearms for ‘traditionally lawful purposes, such as self-defense within the home’ (FindLaw, n.d.). The Amendment II as passed by the Congress states that â€Å"a well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed† (cited in Young, 2007, p.222). The Second Amendment came into effect in the second half of the 20th century. As described in a web document (‘Constitutional Topic: The Second Amendment’, n.d.), gun control advocates perceived the Amendment in another way referring to the mounting level of violence in the society and the role played by firearms in those issues; and in contrast to this view, firearm enthusiasts claimed that the opponents’ arguments are against people’s freedom and hence they interpreted the 2nd Amendment just as fiercely. Evidently, some phrases in the Second Amendment paved the way for a series of debates. The English Bill of Rights 1689 has greatly influenced the 2nd Amendment to the US Constitution. The right to have arms has been considered as one of the fundamental natural right throughout the English history. In District Columbia v. Heller (2008), the Supreme Court makes reference to the English rights concerning the possession of arms by individuals. The growing threat of terrorism in Western countries, particularly in the United States, justifies the Second Amendment. Since US is considered to be prone to terror attacks since the 9/11, this Amendment would raise the level of security of US people. Referring to the increasing rates of crimes in the country including robbery, kidnapping, and sexual assaults, this Amendment would help people to be more self-defensive. However, some law professionals do not support Amendment II arguing that this would worsen the gun crimes in the country. As stated in some documents (‘The Second Amendment to the United

Maximum height of a projectile motion Lab Report

Maximum height of a projectile motion - Lab Report Example Since the gravitational pull acts downwards (vertical sense) then the horizontal and vertical components can be treated separately. Thus, the maximum height traveled by the body upwards can be calculated (Warren 73). For instance, a cannon shoots a ten kilograms cannon balls straight upwards, with a muzzle velocity of say 860 m/s, and then ignoring air resistance the maximum height attained by the cannon balls can be found. Taking the initial velocity in the vertical direction of the cannon ball to be vi and bearing in mind that the acceleration due to gravity is acting in the opposite direction (downwards). At the point when the cannonball attains the maximum height, it has zero velocity thus vf = 0. At this point, the ball starts to accelerate downwards. The equation below is used to calculate the cannon’s highest point that it reaches before it starts falling downwards (Warren 72). Thus, the ball will go up to thirty-eight kilometers or approximately twenty-four miles (Serway, Jewett and Peroomian 20). Theoretically, the ball should come back and attain the velocity same as the launching velocity as it falls at the same point of launching, that is 860 m/s. At each angle of elevation, the initial velocities were noted (McGinnis 73). The same procedure was repeated for the ball with a mass of 5.50 grams. The results were tabulated in a table as shown below: The result of the heights corresponding to every velocity was obtained, and curves were drawn for every mass. The results were as shown below. The table shows the results obtained for the ball of mass 9.5 g. The data obtained for the two balls was tabulated, and the maximum height reached by the ball at each launch relative to the angle of elevation was found (Breithaupt 26). The maximum height was determined using the formulae in the equation (7). H max = †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. (7).
