The Eiffel Tower Essays - Structural Engineers, Eiffel Tower

The Eiffel Tower The Eiffel Tower The Eiffel tower is the trademark of Paris, France. With the tower being 984ft, it's kind of hard not to notice it. The tower has a restaurant, radio and television transmitter and more. Gustave A. Eiffel created the tower to enter it in the worlds fair. It was made with wrought iron and had medium wind resistance. Gustave started in 1889 and completed in 1910. Gustave A. Eiffel created the Eiffel Tower. Eiffel oversaw the construction with such success that in 1866 he founded his own company and soon became known for his wrought iron structures. Starting in 1872 he attracted foreign contracts, and in 1877 he created over the Douro River in Porto, Portugal, a steel arch bridge 525 ft in height. The Eiffel Tower is a landmark and an early example of wrought-iron construction on a gigantic scale. It was designed and built by the French civil engineer Gustave Alexandre Eiffel for the Paris World's Fair of 1889. The tower, without its modern broadcasting antennae, is 984 ft high. The lower section consists of four immense arched legs set on masonry piers. The legs curve inward until they unite in a single tapered tower. Platforms, each with an observation deck, are at three levels; on the first is also a restaurant. The tower, constructed of about 7000 tons of iron, has stairs and elevators. A meteorological station, a radio communications station, and a television transmission antenna, as well as a suite of rooms that were used by Eiffel are located near the top of the tower. Eiffel's work combined expert craftsmanship and graceful design. Completed in 1884, it was for a time the highest bridge in the world, winning Eiffel's factory a worldwide reputation for excellence. Eiffel cast Frederic Auguste Bartholdi's colossal statue Liberty Enlightening the World, which was dedicated in New York in 1886. Soon after, he began work on his greatest project, the building of the Eiffel Tower. It was completed in 1889 for the celebration of the centennial of the French Revolution (1789-1799). Eiffel was not a popular man when he started building the huge steel-frame tower that would overlook Paris. The structure was just too different and the critics didn't like it at all. In 1887, the leading artists of Paris signed a petition to have what they regarded as a monstrosity torn down immediately. Fortunately for Paris, their call was ignored. And though Parisians didn't like it at first, they began to grow fond of the structure they initially called a Cyclops and a skeleton. The Eiffel Tower was completed in 1889, just in time to show off for the World's Fair, being held that year in Paris. The tower was also a sign of things to come. Eiffel was taking full advantage of a new building material, structural steel. With it he took the first step in creating what would become the modern skyscraper. The imposing tower-constructed of 7,000 tons of iron in 18,000 parts held together by 2,500,000 rivets rises to a height of 984 ft and continues to dominate the Paris skyline. In the early 1890's Eiffel gave up the daily management of his business and became absorbed in the new science of aerodynamics. Emile Nouguier and Maurice Koechlin, the two chief engineers in Eiffel's company, had the idea for a very tall tower in June 1884. It was to be designed like a large pylon with four columns of lattice work girders, separated at the base and coming together at the top, and joined to each other by more metal girders at regular intervals. The company had by this time mastered perfectly the principle of building bridge supports. The tower project was a bold extension of this principle up to a height of 300 meters, equivalent to the symbolic figure of 1000 ft. On September 18 1884 Eiffel registered a patent "for a new figuration allowing the construction of metal supports and pylons capable of exceeding a height of 300 meters". Eiffel's clockwork precision had enabled him not only to meet his deadline, but to build the structure with the loss of only one life, that of a worker who fell from the first platform while apparently showing off for his girlfriend after the bell had sounded ending the working day. The Eiffel tower is the trademark for Paris. Even though The people of Paris didn't like the tower, they got to like it, so did the tourist. Then they found out about the good transmitting with the radio and the television. Now the Eiffel tower is a major tourist attraction, and one of

Multidisciplinary Rehabilitation for Individuals with Chronic Musculoskeletal Pain essays

Multidisciplinary Rehabilitation for Individuals with Chronic Musculoskeletal Pain essays This article on the multidisciplinary approach to the treatment of musculoskeletal pain was of particular interest to me. In my practice, I deal with many patients who have chronic pain. Sometimes the pain the experience is an element of physical disease. Sometimes the pain is an element of psychosocial distress. Often times my severely depressed patients present which chronic pain issues. Depending on the patients insight into his or her disease, it may be easy to address the psychological elements of pain. Other times, patients seek relief via escalating doses of narcotic pain medication, whether prescribed or illicit, in an attempt to numb the pain, caring little from where the pain comes. There is often times a disconnect between me and the patients medical provider regarding treatment, so an article which recommended a multidisciplinary approach was of specific interest to me. In this article, it was noted that in more than 90% of the cases of chronic musculoskeletal pain there can be identified no organic reason for the pain. The researchers identified several associated secondary stressors with chronic pain such as unemployment, interpersonal problems, sleep disruption and psychosocial disruption. Depression and anxiety were noted to be the most common psychological problems associated with chronic pain. These mood issues can also effect the patients perception of the disease in their present life. Anxiety related to pain can often be traced to the patients fear that the pain represents an underlying element on ongoing damage to the body. The patient may then limit activity, fearing harming the body further. In this study it was believed that the better the patient was able to understand his or her symptoms and the impact of his or her symptoms on daily life, the better the patient would be able to function and remain healthy as possible physi cally, mentally and spiritually.

Effects of different corticosteroids on the immune system Research Paper

Effects of different corticosteroids on the immune system - Research Paper Example The glucocorticoids are used in replacement therapies for various inflammatory diseases, in severe allergic reactions such as asthma, in the management of some autoimmune disorders and in some cancers as well (Howland, Mycek, Harvey, Champe, & Mycek, 2006). The therapeutic role of corticosteroids has expanded since their first application for the treatment of reheumatoid arthritis in 1949 (Doan, Melvold, & Waltenbaugh, 2005). Different therapeutic corticosteroids are available for replacement therapies, and they play an important immunosuppressive role by mediating the adaptive and innate immune cells of our body. Cortisol is the basic and fundamental glucocorticoid produced in the human body. The three main functions for which corticosteroids are widely used therapeutically include their use as anti-inflammatory agents, for suppression of the immune system, and as a replacement therapy for replacing the hormones not produced at normal levels by the body (NHS Choices, 2013). The prod uction of cortisol reaches its peak during the early morning followed by a drop and then again a peak, relatively smaller, in the late afternoon. Cortisol has various body functions. It promotes the production of glucose and protein catabolism and the degradation of lipids by lipolysis. Cortisol increases the body’s resistance to stress by elevating the blood glucose levels, which helps in more energy production, and fighting stress situations such as cold, trauma, infections, fright, and bleeding. Cortisol also plays an important role in decreasing the blood cell levels which include eosinophils, basophils, monocytes, and lymphocytes. This particular action is important in the treatment of leukemia. The lowering of peripheral lymphocytes and macrophages also helps in mediating an anti-inflammatory action. Cortisol increases the production of growth hormone (Howland et al., 2006). The immunosuppressive action of corticosteroids is used in the treatment of many autoimmune diso rders such as inflammatory bowel disease, systemic lupus erythematous, and rheumatoid arthritis. Corticosteroids are also helpful in treating several renal autoimmune diseases such as nephrotic syndrome (Doan, Melvold, & Waltenbaugh, 2005). Numerous corticosteroid preparations are used for therapeutic purposes. Hydrocortisone is used as a topical preparation or in an injectable form. The injections are given to reduce inflammation in joints and tendons of affected individuals. Dexamethasone is used in acute conditions such as severe breathing allergic reactions, and is utilized mainly in the intravenous form. Prednisolone is used in several autoimmune conditions and allergic reactions and is available in suppository form, injections and as oral tablets. Fludrocortisone’s fundamental usage is for Addison’s disease, in which there is a deficiency of normal body steroid production (NHS Choices, 2013). Cortef contains hydrocortisone and is readily absorbed from the gastroi ntestinal tract. It has a wide variety of indications including rheumatic disorders, adrenal insufficiency, SLE, dermatological conditions such as psoriasis, seborrheic dermatitis, exfoliative dermatitis, allergic conditions such as asthma, serum sickness, rhinitis, drug hypersensitivity reactions, ophthalmic diseases such as conjunctivitis, keratitis, herpes zoster ophthalmicus, optic neuritis, haematological diseases such as acquired haemolytic anemia, idiopathic thrombocytopenic

The inferior (distraught) parts of the same species would slowly vanish, leaving just the predominant (advantaged) parts of the species. Natural selection is the protection of a functional advantage that empowers members of a species to contend better in nature. Natural selection is the naturalistic equal to local rearing (Vincent and Joel 67). Throughout the hundreds of years, human breeders have delivered sensational changes in local creature populaces by selecting people to breed. Breeders eliminate out undesirable attributes bit by bit over time. Additionally, natural selection wipes out inferior species step by step over time. However, a concept referred to as uniformitarianism is against the theory of natural selection. The theory states that the evolution took place through the influence of some natural forces such as earthquakes and floods. The climate of the earth has changed during the course of history. The majority of scientists agree that human activities are resulting to the increase of greenhouse gasses into the atmosphere. Human activities since the period of the industrial revolution have increased the level of greenhouse gasses in the atmosphere. Carbon dioxide one of the major greenhouse gasses is produced through the process of burning fossil fuels, deforestation, and land use changes (Woodward 69). Methane the second type of greenhouse gasses is produced through the process of decomposing wastes in landfills, rice cultivation, and manure management. This means that human activities such as farming and use of fossil fuels have increased the level of greenhouse gasses in the atmosphere. In my area of origin, there is the problem of contamination of drinking water. This is occurring through the contamination of rivers, reservoirs, and lakes in the region. The government is trying to guarantee that there is a proper way of disposing of waste from the factories in

A Creole women must be beautiful, motherly, a good wife to their husbands. "They were women who idolized their children, worshiped their husbands, and esteemed it a holy privilege to efface themselves as individuals and grow wings as ministering angels" (pg. 8). This is what was expected of women, it was their place in Creole society. However Edna awoke from this social institution in which women have a predestined life, which they must live the Creole way. Edna became conscious of the fact that this culture is what kept her from doing what she really wanted to do, to love, live, be independent and to express herself as an individual. Throughout the work Edna is constantly awakening from her naps, constantly awakening to a world she cannot escape. "Each morning she awoke with hope..." (pg. 104) and "When Edna awoke with the conviction that she had slept long and soundly ." (pg. 37), these are a few examples of Edna awakening from slumber. It is only through these frequent naps that Edna defies the constraints of the world she lives in. Her awakening from her naps is symbolic of her awakening from the Creole culture and her husband. Not only does the title symbolize Edna's awakening from her social constraints, but the title also conveys Chopin's opinion of society and Edna. By entitling her novel The Awakening, she is stating that there is an injustice to women in society that people need to conscious of, which people need to awaken to and that Edna has indeed awakened to it.
