Quotes from James K. Polk

Quotes from James K. Polk Read the words of James K. Polk, the eleventh President of the United States.   No President who performs his duties faithfully and conscientiously can have any leisure. Foreign powers do not seem to appreciate the true character of our government. There is more selfishness and less principle among members of Congress...than I had any conception of, before I became President of the U.S. In executing this power by levying a tariff of duties for the support of Government, the raising of revenue should be the object and protection the incident. To reverse this principle and make protection the object and revenue the incident would be to inflict manifest injustice upon all other than the protected interests. Well may the boldest fear and the wisest tremble when incurring responsibilities on which may depend our countrys peace and prosperity, and in some degree the hopes and happiness of the whole human family. I cannot, whilst President of the United States, descend to enter into a newspaper controversy. I prefer to supervise the whole operations of Government myself rather than entrust the public business to subordinates and this makes my duties very great. Well may the boldest fear and the wisest tremble when incurring responsibilities on which may depend our countrys peace and prosperity, and in some degree the hopes and happiness of the whole human family. Although in our country the Chief Magistrate must almost of necessity be chosen by a party and stand pledged to its principles and measures, yet in his official action he should not be the President of a party only, but of the whole people of the United States. The world has nothing to fear from military ambition in our Government. While the Chief Magistrate and the popular branch of Congress are elected for short terms by the suffrages of those millions who must in their own persons bear all the burdens and miseries of war, our Government can not be otherwise than pacific.

The Life and Work of Howard S. Becker

The Life and Work of Howard S. Becker Howard S. Howie Becker is an American sociologist renowned for his qualitative research into the lives of those otherwise classified as deviant, and for revolutionizing how deviant behavior is studied and theorized within the discipline. The development of the subfield focused on deviance is credited to him, as is  labeling theory. He also made significant contributions to the sociology of art. His most notable books include  Outsiders  (1963),  Art Worlds  (1982),  What About Mozart? What About Murder?  (2015).  Most of his career was spent as a professor of sociology at Northwestern University.   Early Life Born in 1928 in Chicago, IL, Becker is now technically retired but continues to teach and write in San Francisco, CA, and Paris, France. One of the most prolific living sociologists, he has about 200 publications to his name, including 13 books. Becker has been awarded six honorary degrees, and in 1998 was given the award for Career of Distinguished Scholarship by the American Sociological Association. His scholarship has been supported by the Ford Foundation, the Guggenheim Foundation, and the MacArthur Foundation. Becker served as President of the Society for the Study of Social Problems from 1965-66, and is a lifelong jazz pianist. Becker earned Bachelors, Masters, and Doctorate degrees in sociology from the University of Chicago, studying with those considered a part of the Chicago School of Sociology, including Everett C. Hughes, Georg Simmel, and Robert E. Park. Becker himself is considered a part of the Chicago School. His career in studying those considered deviant began thanks to his exposure to marijuana smoking at Chicagos jazz bars, where he regularly played piano. One of his earliest research projects focused on marijuana use. This research fed into his widely read and cited book  Outsiders, which is considered one of the first texts to develop labeling theory, which postulates that people adopt deviant behavior that breaks social norms after they have been labeled deviant by others, by social institutions, and by the criminal justice system. Importance of His Work The importance of this work is that it shifts analytic focus away from individuals and to social structures and relations, which allows for the social forces at play in producing deviance to be seen, understood, and changed, if need be. Beckers groundbreaking research resonates today in the work of sociologists who study how institutions, including schools, use racial stereotypes to label students of color as deviant problems that must be managed by the criminal justice system, rather than in-school punishment. Beckers book  Art Worlds  made important contributions to the subfield of the sociology of art. His work shifted the conversation from individual artists to the whole field of social relations that make the production, distribution, and valuation of art possible. This text also proved influential to the sociology of media, media studies, and cultural studies. Another important contribution that Becker made to sociology was to write his books and articles in an engaging and readable way that made them accessible to a wide audience. He wrote prolifically also on the important role that good writing plays in disseminating the results of sociological research. His books on this topic, which also serve as writing guides, include  Writing for Social Scientists,  The Tricks of the Trade, and  Telling About Society. Learn More About Howie Becker You can find much of Beckers writing on his website, where he also shares his music, photos, and favorite quotes.

Nursing Assignment Example | Topics and Well Written Essays - 250 words - 3

Nursing - Assignment Example The nurse failed to follow the 6 rights prior to the administration of a medication. This went against the required nursing practice. The consequence of this act put the patient’s life at risk because the patient had a negative effect from the dosage administered. The nurse went ahead and ignored filling out the incident report. The physician and the supervisor get information from filled incident reports. Failing to fill implied that the nurse was concealing certain crucial information. The nurse’s act to ignore the incident report violated rules of practice in caregiving. It further put the patient’s life at risk which is opposite to what nurses should do. Patents are entitles to a healthy life, and the caregivers should do their best to see this done. However, the nurse’s actions did not match this requirement. Failing to fill out the incident report did not depict an aspect of duty to care, since it encompasses all that is required of the nurse. The nurse who failed to verify the correct dosage as a witness is also implicated in the failure to fulfill duty to care. This is a procedure carried out in order to ensure that the patient’s life is not endangered, given the practices undertaken by the nurses. This nurse ignores her duty and the result is a negative effect on the patient. This does not only raise concerns in the care giving institutions, but also externally, since patients have a right to proper treatment and administration of medication. Concealing what had unfolded during shift change would complicate the matter even further. During shift report, the nurse had already presented what had happened, evidenced by the fact that the patient was in ICU. Contradiction of information between that presented during shift report and the one the nurse is to present by filling out the incident report would require that investigation into the matter be undertaken. Nursing ethics require transparency and accountability (Ginny, 2009).

Consumer Research on Ethical Consumption Essay Example | Topics and Well Written Essays - 3250 words

Consumer Research on Ethical Consumption - Essay Example General assumption on relationship between attitudes and behavior is the consistency. This is known as principle of consistency which means expectation on consistency of one’s behavior with the attitudes hold by them. Furthermore it means people are rational and try to behave rationally at every time. Though this principle is through, it is clear that consumers do not always follow that. Sometimes it is able to experience irrational behavior. For an instance, majority of consumers are smoking cigarettes while knowing this consumption causes heart diseases and lung cancers. Literature relevant to theory of reasoned action and theory of planned behavior are significant theories that discussed this attitude-behavior relationship in-depth manner. Attitude is defined as a permanent, general evaluation regarding people or person, objects, issues or advertisements (Soloman et.al, 2010). Difficulty of changing and nature of evaluating something are discussed as the characteristics of attitude according to above definition. Relationship between attitude and behavior is presented by Fishbein and Ajzen (1975) based on theory of reasoned action. As theorized by Gordon W. Allport in 1935, there is a multidimensional relationship in between attitude and behavior but not one-dimensional relationship. It means attitude is a complex system that consists with individual’s belief regarding the object, feeling on the object and action tendencies towards the object.

A raisin in the sun coursework Essay Example for Free

A raisin in the sun coursework Essay In this essay I am going to analyse how Lorraine Hansberry presents the transformation of Walter in the play A raisin in the sun. The pages Im going to concentrate on are pages 1787 and 1788. A raisin in the sun portrays a few weeks in the life of the Youngers, an African-American family living on the South Side of Chicago in the 1950s. When the play opens, the Youngers are about to receive an insurance check for $10,000. This money comes from the deceased Mr. Youngers life insurance policy. Each of the adult members of the family has an idea as to what he or she would like to do with this money. The matriarch of the family, Mama, wants to buy a house to fulfil a dream she shared with her husband. Mamas son, Walter Lee, would rather use the money to invest in a liquor store with his friends. He believes that the investment will solve the familys financial problems forever. Walters wife, Ruth, agrees with Mama, however, and hopes that she and Walter can provide more space and opportunity for their son, Travis. Finally, Beneatha, Walters sister and Mamas daughter, wants to use the money for her medical school tuition. She also wishes that her family members were not so interested in joining the white world. Beneatha instead tries to find her identity by looking back to the past and to Africa. Later on in the play, the Youngers fight over their competing dreams. Ruth finds out that she is pregnant and starts to worry about the financial problems that may happen if she keeps it. Mama puts $3,500 down payment on a house and gives $6,500 to Walter from which he has to give Beneatha some for her medical school tuition. Walter on the other hand doesnt give Beneatha her share of her money, instead gives it to Willy his friend who runs away with it. The house is in Clybourne Park, an entirely white neighbourhood. When the Youngers future neighbours find out that the Youngers are moving in, they send Mr Lindner, from the Clybourne Park Improvement Association, to offer the Youngers money in return for staying away. The Youngers refuse the deal. In the meantime, Beneatha rejects her suitor, George Murchison, whom she believes to be shallow and an assimulationist. Subsequently, she receives a marriage proposal from her Nigerian boyfriend, Joseph Assegai, who wants Beneatha to get a medical degree and move to Africa with him. The Youngers eventually move out of the apartment, fulfilling the familys long-held dream. Their future seems uncertain and slightly dangerous, but they are optimistic and determined to live a better life. They believe that they can succeed if they stick together as a family and resolve to defer their dreams no longer. Various stage directions are used to show Walters feelings for example, when Ruth informs Walter that Mr Lindner is here a long minute passes and Walter slowly gets up from his room. This shows that Walter is not eager to meet Mr Lindner so he takes his time. When Walter slowly and awkwardly walks out of his room passing the back of his sleeve across his mouth from time to time makes him seem as if he is a small chid who is sloppy and awkward. This is how he behaves throughout the play and shows the childish side of him. When Walter looks down at his boys eyes he realises that Travis is the 6th generation in his family to live in America and should look to set an example for future generations. While Walter talks to Mr Lindner he looks around and shifts from one foot to the other and makes short pauses in his speech showing that he is unsure and frightened about speaking out aloud in front of his family. He tries to get the point across that they are very plain people. Walter again looks away from Mr Lindner and down at his shoes and then back up at him. This shows that he cant maintain eye contact with Mr Lindner. This makes Walter feel shy because he is speaking to someone who is higher classed and who he feels is superior to him. He again tries to get the point across that they are plain people by telling Mr Lindner their current situation such as how he has been a chauffer most of his life and how Ruth is a domestic worker in peoples kitchens. All this confuses Mr Lindner as he doesnt know what Walter is trying to get across instead he listens to him and see what he has got to say. Walter now starts to tell Mr Lindner how his father almost beat a man to death once because this man called him a bad name or something. Walter asks Mr Lindner if he knows what he is talking about, he replies no, Im afraid I dont this makes Walter feel as if he is the only one that understands what it feels like so he gains confidence in himself and straightens up. Walter tries to get another point across by saying that he came from people who had a lot of pride and now they dont have the same pride. Walter tries to make out that they are still very proud and how his sister is going to be a doctor. Walter contradicts himself as in the beginning when he was arguing with Beneatha he mentioned that being a doctor is more of a males role and she wouldnt be able to become one. Walter now starts to cry while facing Mr Lindner eye to eye this makes Walter feel bad about what he has done with the money. Walter now decided to tell Mr Lindner that they are moving into the house because his father had earned it. This shows that Walter has recognised his responsibility and best interest for his family at heart. Walters character has evolved from a young child into manhood making him a hero of the family. Walter now has all the confidence to look Mr Lindner absolutely in the eyes and tell him we dont want your money. Walter finishes with a very definite statement. Doing this makes Mr Lindner feel as he is an obstruction and so should leave. The family are all excited about the wise decision Walter has made. The audience feel that in the beginning of the play Walter is selfish and money hungry because he doesnt listen to any member of his family and only thinks about trying to get rich quickly. In the end Walter had realised what a fool he had been after losing the money his mother had trusted him with. Now he should listen to his families needs and do what he thinks is right. By making the wise decision of moving into the house he makes the audience feel as if he has become a true man and a hero to his family. Walter is virtually a new person now which people like more than what he was before. The character of Mr. Lindner makes the theme of racial discrimination prominent in the plot as an issue that the Youngers cannot avoid. The governing body of the Youngers new neighbourhood, the Clybourne Park Improvement Association, sends Mr. Lindner to persuade them not to move into the all-white neighbourhood. Mr. Lindner and the people he represents can only see the colour of the Younger familys skin, and his offer to bribe the Youngers to keep them from moving threatens to tear apart the Younger family and the values for which it stands. Ultimately, the Youngers respond to this discrimination with defiance and strength. The play powerfully demonstrates that the way to deal with discrimination is to stand up to it and reassert ones dignity in the face of it rather than allow it to pass unchecked. In my opinion I think Walter is like any other American- African in that time. He believes that money is the only thing he needs to solve all his problems but little does he know that he needs to listen to his family and not just himself. I also think that all the male roles such as Willy and his friends are bad influences on Walter as they persuaded him to give them his money which they ran off with. However the female roles such as mama and Ruth were a good influence as they all stuck together even when Walter was against them and helped Walter to see what he is throwing away. Lorraine Hansberry is trying to say that Black people in the 1950s experienced a life of discrimination in one way or another. They got here today by having defiance and strength in themselves. Even though they were not treated as equals by some white people, however they made a stand which gave them dignity and the power to be treated as equals. Though black people try to fit into a white neighbourhood they should still remember their roots and how they got here.

Jacob :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Jacob, the son of Isaac and Rebekah, and the twin brother of Esau, was born in Canaan, around 2,000 BC. Even before his birth, great things had been predicted of him by the Spirit of the Lord. It was prophesized that although he was the younger born of the twins, he should have dominion, and be the father of a great and powerful nation. The predictions also included his descendents would reign supreme over all the descendents of his elder brother, Esau (Blunt 123).   Ã‚  Ã‚  Ã‚  Ã‚  Jacob first appears in the Bible in the book of Genesis. The Bible says that Esau was the firstborn of the twins. â€Å"Afterward his brother came out, with his hand gripping Esau’s heel; so he was named Jacob.† (Genesis 25:26). The boys grew up, and Esau was described as a skillful hunter, while Jacob was a quiet man, living in tents. Once when Jacob was cooking a stew in his tent, Esau came in from the from hunting in the fields and was famished. Jacob told Esau he would share with him his stew on the condition that Esau renounce his birthright to him. Esau accepted. Later, as their father, Isaac sat on his deathbed, he blessed Jacob, who was dressed in fur clothing to imitate Esau who had more body hair than Jacob. Isaac thought it was Esau he was blessing (Meeks 41). After this, Jacob’s mother advised him to go live with his Uncle Labon in Padan-Aram – afraid that Esau would become vengeful and kill Jacob after he tricked their fath er into giving him his blessing of the first born. On his way to Padan-Aram, he came to Bethel to sleep for the night. He took a stone and placed it under his head. Some critics believe that a correction to our traditional misunderstanding of this stone placing is that Jacob took the stone and placed it not under his head as a pillow, but rather â€Å"at his head† for protection. While sleeping here, he dreams of a ladder set up on the earth, reaching all the way up to heaven. He saw the angels of God ascending and descending on it. The opinion of some critics is that what Jacob saw in his dream was not a â€Å"ladder† but a â€Å"stairway†. Some years ago, at a site twenty-five miles northeast of Bethel, archaeologists uncovered the remains of a divided stone staircase leading from the city down to its water source.

An Introduction to Adolescent Depression and Suicide

Teenage angst is often referred to normal during that an unfortunate phase called adolescence through which many parents hope their children will emerge unscathed, and suffer through it with a philosophical attitude.Many incidents of unreasoning anger, social withdrawal, apathy and refusal to communicate are taken as signs of this phase and no more. However, these behaviors have also been identified as signs of adolescent depression, and those who are at-risk may very well be diagnosed with this condition. Parents would be well advised to eye such incidents with some attention, especially if it occurs over a prolonged period of time.True adolescent depression is made more difficult to diagnose this is the rebellious phase of teenagers, a time when they are most difficult to communicate with.This period of development is marked with transient period of depression-like signs such as sadness and loss of self-worth due to the normal process of maturation and its concurrent stresses, such as sexual development and conflicts with authority figures such as parents.Other stressful events, such as a romantic break-up or death in a family may be difficult for some teenagers, especially those with low self-esteem to cope with. When the behavior is persistent, this could already a depressive disorder (â€Å"Adolescent depression,† 2005).Adolescent depression is thought to affect up to 5% of children between the ages of 9 and 17, although as much as 15% exhibit some symptoms of depression at any given time. The condition affects the functionality of the adolescent that becomes apparent in poor performance in school, deteriorating social interactions, and hostile family relationships and may eventually lead to suicide.Many of those affected are seldom diagnosed and treated properly, and some experience depression before the age of seven. Major adolescent depressive disorder, the most severe degree of the condition is diagnosed similar to the criteria for major depress ive disorder in adults (Bhatia and Bhatia, 2007).There are many conditions for which adolescent depression can become a long-term problem, including depression in adult life and suicide. Some adolescents begin their depressive periods in early childhood, which becomes worse as the stress of life becomes more intense.It would be of paramount importance, therefore, to be able to distinguish between a teenager â€Å"acting out† and true adolescent depression. This paper aims to provide a comprehensive overview of adolescent depression, its symptoms and diagnosis, treatment and the risk of suicide associated with it.MethodologyScholarly articles detailing the known symptoms, risk factors, statistics and treatment protocols for adolescent depression and associated suicide were included in this paper to condense the information about the condition.These include articles from the American Family Physician, a peer reviewed journal of the American Academy of Family Physicians because adolescent depression is mostly a problem that beset families and are best solved at this societal level.Articles from the New England Journal of Medicine, American Journal of Psychiatry and the University of Pennsylvania Health System were also included to support the findings, as well as current event articles on depression screening in schools and the interaction of sexual activity and depression.Studies on the suicide rates associated with adolescent depression were taken from the British Medical Journal and American Journal of Psychiatry.A public health survey conducted by the Washington County Department of Public Health and Environment on teenagers was also included to provide a subjective perspective of adolescent depression and concepts of suicide.There is also the issue regarding the efficacy of current treatment methods for adolescent depression, elucidated with reports from Stanford University, The British Journal of Psychiatry and a reprinted article in Pediatric Nursin g.Results survey of teenagers on adolescent depression and suicideIn 2000, the Washington County Department of Public Health and Environment conducted two surveys designed by the Youth Risk Behavior (YRB) Endowment Advisory Committee to identify discover the main points to cover for managing depression, suicide and overall mental health of teenagers in Washington County.Of the 17,726 teens in the area, 1,875 adolescents in grades 7-12 responded to two surveys, namely survey 1 â€Å"Depression & Suicide: How Can We Make A Difference† and survey 2 â€Å"Communities For Teen Health†.In the first survey, 87% of the respondents believe that depression and suicidal thoughts are a big problem among teens today.When asked what kind of information they believed would benefit at-risk teens, 85% believed parents should be able to recognize signs of depression in their children and to take it as a serious matter while 81% maintained teens should be able to talk to friends about ho w they are feeling.Many (74% and 73% respectively) believed it was important for teens to be able to recognize if they are depressed and if others are depressed and to know where to go if they suspect they or others suffer from depression. Ninety-three percent of respondents believed guest speakers, motivational or other teens that have gone through depression and suicidal thoughts would be the best source of this information followed by television at 60% and caring adult at 54%.Having open communication, acquiring better understanding and reducing the amount of stress were the top answers for what adults and other teens can do to influence mental health of the youth.For the second survey, which investigated the involvement of the community in this condition, 31% of the respondents believed education was the venue most utilized for addressing the problem. Someone to talk to and friends tied at 26% for the best way depressed teens can be helped while 80% believed better awareness for parents and teachers was crucial.Twenty-one percent of the respondents believed more money should be spent on more education while 19% thought money would be well spent on media (â€Å"Adolescent depression & suicide opinion survey,† 2001).Symptoms and signsâ€Å"Major depressive episodes for adults and adolescents are similar in criteria†. Over a two-week period, comparative tabulation of the major symptoms is provided (Bhatia and Bhatia, 2007).

Indian Removal Act Essay

In 1791, the Cherokee Nation was allocated land in Georgia during a treaty with the U.S. In 1828, whites wanted to reclaim this land not only for settlement purposes, but because of the discovery of gold. President Jackson and the U.S Congress passed a policy of Indian removal for all lands east of the Mississippi River; this was known as The Indian Removal Act of 1830. As Georgia tried to reclaim this land, the Cherokee protested and took their case to the U.S Supreme Court, known as Worcester vs. Georgia. The act was instituted to authorize the Native Americans to move west. Native tribes included Choctaw, Creek, Cherokee, Chickasaw, and Seminole. While some tribes agreed to move west, many refused. The Native Americans resisted with great force as well as the Cherokee Indians being a significant part of the disagreement with the Supreme Court and Jackson. The Supreme Court favored the Cherokee Nations calling it â€Å"unconstitutional,† which caused controversy between Geor gia officials. In turn, the Georgia officials with the support of Jackson led to a forced march in 1838 with the removal of all Cherokee Indians known as The Trail of Tears. This march is also known to the Cherokee’s as â€Å"The Trail Where They Cried,† because approximately 4,000 died. Federal troops were given orders to remove 15,000 Cherokee people to their new home in Indian Territory, today known as Oklahoma. This removal violated the Supreme Court’s Decision. The repercussions of this removal led to many deaths of  Native Americans, not only from the force of removal, but from disease, starvation and the cold during their transition to their new home west of the Mississippi. Poverty of many relocated Indians lasted close to 100 years. The resources they gained while living in the land that they were stripped from, not only led to this poverty, but the livelihood of many natives were broken. International treaties were broken because of Jackson’s decision to go against the Supreme Court. It took over 30 years to removal all native tribes west. The Seminoles refused to leave calling the Act â€Å"unjust.† This resulted in the Second Seminole war lasting 7 years from 1835-1842. Jackson spent millions of dollars during his administration for this to succeed. â€Å"By the end of his presidency, Jackson had signed into law almost seventy removal treaties, the result of which was to move nearly 50,000 eastern Indians to Indian Territory—defined as the region belonging to the United States west of the Mississippi River but excluding the states of Missouri and Iowa as well as the Territory of Arkansas—and open millions of acres of rich land east of the Mississippi to white settlers (U.S. Department of State, 2014).† While some including the natives view this Act and unconstitutional to the treaties in which were implemented, others view this as a necessity to continue to make the government prosper. Many natives lost their lives. America is what it is today because of the mast amount of treaties and Act s placed upon us by our historical leaders. Although this Act went against the rights of settlers, domestic and international trade may not be what it is today if this was not forced by the powers of the Jackson administration. This takes us to the controversy of moral character and rights vs. the prosperity of the American people. Politics and economic infrastructure should be based upon both good moral character as well as the implementation of governing laws to ensure our prosperity as a nation.

Free Essays on King Auther

King Arthur is mostly known for his Kingly leadership, his loving rule, and even his ruthless judgment of Lancelot and Guinevere. The name Arthur came from Artorius, which is a Roman gen. King Arthur was the son of Uther Pendragon who defeated the barbarians in a dozen battles. Tradition has it that after King Uther’s death there was no king ruling all of England. Therefore, Merlin had placed a sword in a stone, saying that whoever drew it out would be king. Arthur did not know his true status but had grown up living with Sir Ector and Sir Kay. The young Arthur pulled the sword form the stone, and Merlin had him crowned the King of Britain. This lead to the rebellion by eleven rulers, which Arthur put down. In doing so, he conquered a wide empire and eventually went to war with the Romans. In the war against the Romans, Arthur defeated Emperor Lucius and became emperor himself. He returned home on learning that his nephew, Mordred, had raised the standard of rebellio n and took Guinevere, the Queen. After finding the Queen Arthur married her. Guinevere’s father gave Arthur the round table as a gift. Also after landing at home, his final battle took place. The last battle of Arthur took place between him and the forces of his evil nephew, Mordred. Arthur delivered the fatal blow to Mordred in the battle, but in the battle Arthur was struck by an earthly blow, himself. It was then he commanded Sir Bedivere to throw Excalibur back into the lake. The death of Arthur dates back to AD 542 during the fifth century....

Cetacean Characteristics and Facts

Cetacean Characteristics and Facts The word cetacean is used to describe all whales, dolphins and porpoises in the order Cetacea. This word comes from the Latin cetus meaning a large sea animal, and the Greek word ketos, meaning sea monster. There are about 89 species of cetaceans. The term about is used because as scientists learn more about these fascinating animals, new species are discovered or populations are re-classified. Cetaceans range in size from the tiniest dolphin, Hectors dolphin, which is just over 39 inches long, to the largest whale, the blue whale, which can be over 100 feet long. Cetaceans live in all of the oceans and many of the major rivers of the world. Cetaceans are thought to have evolved from even-toed ungulates (a group that includes cows, camels, and deer). Types of Cetaceans There are many types of cetaceans, which are divided largely according to how they feed. The order Cetacea is divided into two sub-orders, the Mysticetes (baleen whales) and the Odontocetes (toothed whales). The Odontocetes are more numerous, comprising 72 different species, compared to 14 baleen whale species. The Mysticetes include species such as the blue whale, fin whale, right whale, and humpback whale. Mysticetes have hundreds of comb-like plates of baleen hanging from their upper jaw. Baleen whales feed by gulping large amounts of water containing hundreds or thousands of fish or plankton, then forcing the water out in between the baleen plates, leaving the prey inside to be swallowed whole. Odontocetes include the sperm whale, orca (killer whale), beluga  and all of the dolphins and porpoises. These animals have cone-shaped or spade-shaped teeth and usually capture one animal at a time and swallow it whole. Odontocetes feed mostly on fish and squid, although some orcas prey on other marine mammals. Cetacean Characteristics Cetaceans are mammals, which means they are endothermic (commonly called warm-blooded) and their internal body temperature is about the same as a humans. They give birth to live young and breathe air through lungs just like we do. They even have hair. Unlike fish, which swim by moving their heads from side-to-side to swing their tail, cetaceans propel themselves by moving their tail in a smooth, up-and-down motion. Some cetaceans, such as the Dalls porpoise and the orca (killer whale) can swim faster than 30 miles per hour. Breathing When a cetacean wants to breathe, it has to rise to the water surface and exhale and inhale out of the blowholes located on top of its head. When the cetacean comes to the surface and exhales, you can sometimes see the spout, or blow, which is the result of the warm air in the whales lungs condensing upon reaching the cool air outside. Insulation Whales do not have a coat of fur to keep warm, so they have a thick layer of fat and connective tissue called blubber underneath their skin. This blubber layer can be as much as 24 inches thick in some whales. Senses Whales have a poor sense of smell, and depending on where they are, they may not be able to see well underwater. However, they have excellent hearing. They do not have external ears but have tiny ear openings behind each eye. They can also tell the direction of sound underwater. Diving Whales have collapsible rib cages and flexible skeletons, which allows them to compensate for high water pressure when they dive. They can also tolerate higher levels of carbon dioxide in their blood, allowing them to stay underwater for up to 1 to 2 hours for large whales.

The Plutonium Experiment - Essay Example The metal in contention is a silvery-white, artificially created, radioactive element and has a melting point of 641 C, so much higher than water and it undergoes five changes between room temperature and melting point and has 6 different physical forms. It's produced when bombarded by neutrons and is a source of energy in reactors and in nuclear explosions. The hapless victims of these experiments are injected with plutonium remaining nameless people referred to only by code numbers until Welsome's efforts uncovered the incident and brought it to the world's attention. One can't help but wonder "who these people were, what happened to them after they left the hospital with the silvery, radioactive metal circulating in their veins - if they ever left at all." This poisoning procedure however left a few loopholes that triggered further investigation into the experiment and cover-ups and denials from the government became a constant in Welsome's research. In choosing the above quote, i t shows how it taps into our humanity and asks the basic question of how far could one go to pursue a question unanswered. The human side appeals to all as all humans have the instinct to survive, prolong and preserve human life.

Rigid Bodies and Application to Snooker Assignment

Rigid Bodies and Application to Snooker - Assignment Example In this project I made a study of main laws and principles of rigid body dynamics from the practical and theoretical point of view: as solutions to theoretical and practical exercises are provided. It required review and deeper study of vector analysis and analytical geometry. Rigid body in mechanics is a system of material points, which doesn't change in time. So it's an idealized system for which the distance between its particles remains constant in time under any motion. Phenomenological mechanics considers rigid body to be a solid matter, in which particles are subjected to internal forces in the form of normal and tangent tensions. Such tensions are caused by external deformations. In case they're re no deformations, there are no tensions inside rigid body. In many cases deformations are so small that can be neglected. So such model is an idealized rigid body, which is not able to deform and even though internal tensions can take place because of external forces. Rigid body is a mechanical system with six degrees of freedom. In order to define the position of a rigid body it's enough to know the position of at least 3 points: A, B, C, which do not belong to one line. In order to prove that rigid body is described by six degrees of freedom we have to take point D. ... (XA-XB)^2+(YA-YB)^2+(ZA-ZB)^2=AB^2=const (XC-XB)^2+(YC-YB)^2+(ZC-ZB)^2=CB^2=const (XA-XC)^2+(YA-YC)^2+(ZA-ZC)^2=AC^2=const Because the lengths of sides of triangle ABC remain the same. So only six coordinates are left independent - rigid body has 6 degrees of freedom. If the body has fixed points the number of freedoms degrees reduces. If rigid body is fixed in one point - it has 3 degrees of freedom, if rigid body can only rotate around one axis is has one degree of freedom, if a body can slide across axis it has two degrees of freedom. In order to understand how x(t) and R(t) change over time we should remind the following formulas: Resultant is v= V+ [w, R] (using vector properties). Kinetic energy of a rigid body is total kinetic energy of rotation plus total kinetic energy of motion: T=.5 mv^2 + 0.5Iw^2 Where I is moment of inertia of a rigid body (mass analogue for rotational motion) Moment of inertia is defined as I=miRi^2. Moment of inertia is additive so moment of inertia of a rigid body is formed from the sum of inertia moments of its parts. Any body, independently from rotational motion or rest has definite moment of inertia. Mass distribution in the limits of a body can be characterized by density: p=m/V So moment of inertia can be expressed as I=piRi^2Vi, if density is constant: I=pRi^2Vi In limit it can be expressed in the following integral: I=R^2dm=pR^2dV The inertia tensor is a set of nine values (which can be written in the form of 3X3 matrix), which shows the dependence of shape and distribution of mass in the rigid body caused by its rotational motion. It's often explained as a scaling factor between angular momentum and angular velocity.1 Inertia tensor matrix has the following structure and its components are calculated
