Endocrine Gland and Adrenaline Essay Example for Free

Endocrine Gland and Adrenaline Essay Adrenaline is a hormone that is produced in the adrenal medulla, which is in the inner adrenal gland. This gland sits atop the kidney. When put under stress this gland is stimulated by the nervous system and releases adrenaline into the blood stream. The release of adrenaline is a three step process. First, the hypothalamus produces hormones that stimulate the pituitary gland. Next, the pituitary gland then produces corticotropin hormones which are hormones that stimulate the adrenal glands that eventually produce adrenaline. In 1895, George Oliver and Edward Schafer discovered that that when the secretions of adrenal glands were extracted and injected into an experimental animal, they could raise blood pressure. The purification of this principle became a matter of interest, and in 1897, John Abel and Albert Crawford thought that they had succeeded when they purified a crystalline principle they named epinephrine. Adrenaline is used for many different purposes. It is used to control hemorrhages in surgery and to treat asthma and other allergies. According to the MSDS, excessive digestion of adrenaline is fatal. It can also be very irritant to eyes and can be absorbed through skin. Adrenaline can also be used to prevent cardiac arrest. Adrenaline can also be found in some nasal sprays to open up nasal passages. This has a short term effect. Adrenaline is helpful to survive in dangerous situations. If you were pinned down by a boulder, adrenaline would kick in and would help you to move the boulder off of you. This process is natural and you can find your way out of unhappy states. When you are put into a dangerous situation like that, your heart rate is elevated and your blood pressure is elevated. Adrenaline redirects blood to large muscle groups so that you are given more strength and stamina to get out of the dangerous situation.

Jonathan Swifts Gullivers Travels :: Swift Gulliver Satire Essays

Jonathan Swift's Gulliver's Travels Jonathan Swift’s, Gulliver’s Travels satirically relates bodily functions and physical attributes to social issues during England’s powerful rule of Europe. Throughout the story we find many relations between bodily features and British and European society. Swift uses this tone of mockery to explain to his reader the importance of many different topics during this time of European rule. Swift feels that the body and their functions relate to political as well as the ration of a society. Swift’s fascination with the body comes from its unproblematic undertone which gives his audience recognizable parallelism to many issues such as political change and scientific innovation. Gulliver’s first adventure takes place in Lilliput. Gulliver swims to a foreign shore after his boat and rowboat capsize due to a fierce storm. Washed upon the shore, Gulliver finds himself tied to the grass surrounded by little bodied people called the Lilliputians. The Lilliputians stood no more than six inches high. During this time Swift recognized that England was also a kind of six inch being that had great influence in Europe. Swift wrote Gulliver’s Travel’s during a time when Europe was the worlds most dominant and influential force. England, despite its small size, had the potential to defeat any nation that might try to conquer them. Swift relates this phenomenon to the small stature of the Lilliputians. They stood a mere six inches high but had the power to siege the mammoth Gulliver. The capability of a nation consisting of miniature people, who are able to capture someone ten-times their size can be seen as reinforcing the capability of a small natio n, such as England, becoming and remaining a great power. Even though this is true, Swift entices a condescending tone to Gulliver’s portrayal of the small Lilliputians, who easily fit into the hands of Gulliver, yet still manage to threaten his life. Even though the Lilliputians are piteously small in Gulliver’s eyes, they do not see themselves the same way. To themselves, the Lilliputians feel they are normal and Gulliver remains the outlandish giant. The unexpected infringement of giant Gulliver into the Lilliputians well-developed society reminds the European society, that size and strength are always relative, and there is no way for Europe to be certain that a Gulliver-like giant, might not arrive and conquer them at any moment. This encounter, between Gulliver and the Lilliputians would put Europe’s confidence in its power in jeopardy.

English Traffic Light Curious Incident Essay

Mark Haddon uses Christopher’s explanation of his confusion to create sympathy for Christopher throughout the book. Christopher is a 15 year old boy with Asperger’s Syndrome. Christopher is extremely intelligent when it comes to maths and science. However, in the common cases of communicating normally, he struggles. He rejects being touched, and when he has absorbed too much information, he can’t handle it; he crouches on the floor and groans. His life is not a normal one; he goes to a special school, has no one he talks to who is of the same age, follows a strict timetable and lives alone with his father. This thing that Haddon has included creates endless sympathy for Christopher. In Chapter 29, Christopher reveals and justifies why he hates metaphors. He thinks that metaphors ‘should be called a lie because a pig is not like a day and people do not have skeletons in their cupboards. ’ This is an example of how Christopher doesn’t think like other people. This makes you have sympathy for him because he doesn’t understand that metaphors are used for; making things more interesting, to make more sense of things by finding similarities. In addition, Christopher’s tone, narrative voice, also contributes to the sympathy for Christopher. The very easy and comprehensible language uses makes you understand how he thinks; ‘And then it started to rain and I got wet and I started shivering because I was cold. And then it was 11:32 p. m. and I heard voices of people walking along the street. ’ After each chapter in the book, which go up in prime numbers, with parts of the actual story, Christopher tends to babble on about memories, calculations and ideas, which sometimes can be slightly boring. Nonetheless; they show how Christopher thinks. This makes you feel sympathy for him because he clearly finds it difficult to focus on one thing; ‘The Hound of the Baskervilles is my favourite book. ’ And it shows that he can only understand maths and science because that’s mainly what he always talks about. Furthermore, the way Christopher expresses his love for his father is different from the usual hug; ‘He held up his right hand and spread his fingers out in a fan. I held up my left hand and spread my fingers out I a fan and we made our fingers and thumbs touch each other. We do this because sometimes Father wants to give me a hug, but I do not like hugging people, so we do this instead, and it means that he loves me. ’ This makes you feel sympathy for him because he can’t spread simple signs and messages to communicate love to people in the same way you’d expect or would find normal. Moreover, he has a strict routine timetable which is unlike others; (pg 192) To add to it, he finds it hard to distinguish between a smiling face and a crying one. (pg2)

Discussion questions Essay

Do you think Kappmeyer should sign the proposal, and why? What pushed USS to stay with conventional technology? My recommendation based on analysis of the case and understanding the basic nature of disruptive technologies, and their impact on the general industry is that Kappmeyer should not sign the proposal. The main reason for that is USS is tying itself to an existing, but dying business model and technology. While this plan may make sense in the short-term, it does not have long-term sustainability. The market has already indicated that it is changing, adapting to minimills, and this trend would likely continue. As minimill technology becomes more sophisticated, their quality and other disadvantages would reduce and they would start competing with integrated manufacturing even in the high-end markets. Unfortunately for USS, there is no silver bullet. Since USS is already invested in the market, they will have to go through a difficult, and expensive, change, or they will end up perishing as the industry changes around them. USS current decided to stay with conventional continuous casting technology simply because they were looking at the shorter-term future, and was not willing to take the financial hit and risk associated with a new disruptive technology. Additionally, they were tying themselves to the requirements of the current customers, and ignoring potentially new users for the future. Did USS team get the right answer to the wrong question? What if, rather than whether USS should install CSP in Mon Valley, Kappmeyer has asked whether USS should invest in or participate in this technology? Would you have answered that question differently than you did when the problem was framed as Mon Valley issue? †¢ What should USS’s next technological move be? Should USS take another â€Å"long shot† to leapfrog ahead of Nucor? Or should it â€Å"get on the ground† neck-to-neck with Nucor, employing a viable commercial technology as soon as possible incrementally improving CSP? Readings †¢ Christensen (1995).

During the period in American history, Spain closed off the mouth of the mississippi (sic) to the Americans and refused to budge or compromise on this matter. John Jays speech to Congress on the negotiations with Spains Don Diego de Gardoqui shows that the Spanish refused to allow the Us to navigate the mississippi (sic). It also illustrates Spains lack of respect for American negotiators because this Treaty was never signed. As Gardoqui alluded to in Jays speech, the states were too divided on issues in the west to sign the treaty. As a result, the vote needed was never acquired to ratify the treaty. The Articles were a laughing stock to the As a result of inability to effectively negotiate foreign policy,maintain and establish domestic policy,and enforce decisions,the central government under the Articles of confederation did not provide America with an effective government between 1781 and 1789.

A Definition of Speech Community in Sociolinguistics

A Definition of Speech Community in Sociolinguistics Speech community is a term in sociolinguistics and linguistic anthropology used to describe a group of people who share the same language,  speech  characteristics, and ways of interpreting communication. Speech communities may be large regions like an urban area with a common, distinct accent (think of Boston with its dropped rs) or small units like families and friends (think of a nickname for a sibling). They help people define themselves as individuals and community members and identify (or misidentify) others. Speech and Identity The concept of speech as a means of identifying with a community first emerged in 1960s  academia alongside other new fields of research like ethnic and gender studies. Linguists like John Gumperz pioneered research in how personal interaction can influence ways of speaking and interpreting, while Noam Chomsky studied how people interpret language and derive meaning from what they see and hear. Types of Communities Speech communities can be large or small, although linguists dont agree on how theyre defined. Some, like linguist  Muriel Saville-Troike, argue that its logical to assume that a shared language like English, which is spoken throughout the world, is a speech community.  But she differentiates between hard-shelled communities, which tend to be insular and intimate, like a family or religious sect, and soft-shelled communities where there is a lot of interaction. But other linguists say a common language is too vague to be considered a true speech community. The linguistic anthropologist  Zdenek Salzmann describes it this way: [P]eople who speak the same language are not always members of the same  speech community. On the one hand, speakers of South Asian English in India and Pakistan share a language with citizens of the U.S., but the respective varieties of English and the rules for speaking them are sufficiently distinct to assign the two populations to different speech communities... Instead, Salzman and others say, speech communities should be more narrowly defined based on characteristics such as pronunciation, grammar, vocabulary, and manner of speaking. Study and Research The concept of speech community plays a role in a number of social science, namely sociology, anthropology, linguists, even psychology. People who study issues of migration and ethnic identity use social community theory to study things like how immigrants assimilate into larger societies, for instance. Academics who focus on racial, ethnic, sexual​ or gender issues apply social community theory when they study issues of personal identity and politics. It also plays a role in data collection. By being aware of how communities are defined, researchers can adjust their subject pools in order to obtain representative sample populations. Sources Morgan,  Marcyliena H.

Power Tactics and Sources of Power Assignment Example | Topics and Well Written Essays - 1000 words

Power Tactics and Sources of Power - Assignment Example Charles was trained to take over from the father since childhood, and he portrayed traits of a great Chief Executive. The training through life involved strict and sometimes harsh treatment from his father that hardened him. Their mother, Mary somewhat protected Bill and David, who were twins. David was athletic and competitive and grew up to be the perfect business partner for Charles. Bill, on the other hand, was the jealous type, always picking fights with David since childhood and often losing. He grew up to be a threat to Charles’s peace, taking Koch industries through strenuous legal proceedings. The brothers owned percentages of Koch industries, each with his shares (Schulman, 2014). Both Charles and Bill Koch had power in Koch Industries. Charles’ sources of power included reward power whereby he was handed the mantle of CEO by his father having been trained since childhood. The father had earlier lost hope in his eldest son Frederick, who was mostly involved in art and theater. Charles also had legitimate power in Koch Industries being the legal CEO. Therefore, he was in charge of many key decisions made within the company and also directed management of funds regardless of how happy or angry others would be with the cash distribution. Charles was well educated in terms of business and market and therefore had expert power which saw him, together with the help of other business partners, grow Koch Industries. Bill’s sources of power included the coercive power that he gained by threatening Charles to make Koch Industries public if he did not meet his demands. These threats were tabled to Charles in writing and got him shaken for some time. Bill always wanted liquidity of assets so that he could benefit from the riches he only had in paper. He even tried to convince Frederick, who had lesser shares in the company to join his course. Bill also had legitimate power in that he owned slightly over twenty
