Components of atmosphere Essay Example for Free

Components of atmosphere Essay The main components of atmosphere are almost invariant. However, the content of water vapor is an exception that it varies with the changing of location, season and time. Oxygen and water vapor plays a significant role on the processes of atmospheric corrosion. Therefore, atmospheric corrosion can be classified in the following three categories: Dry corrosion Damp corrosion Wet corrosion Component Percent/% Component Percent/% Component Percent/% Atmosphere 100 H2O. Components of atmosphere (Impurity excluded, 10? ) 2. 1 Dry corrosion In the absence of significant water vapor, many common metals develop films of oxide. In the presence of traces of gaseous pollutants, copper, silver and other non-ferrous metals undergo film formation which is known as tarnishing. The tarnishing of silver in air is well-known. Tarnishing by hydrogen sulfide may be retarded by moisture if present in very small amounts. 2. 2 Damp Corrosion Damp corrosion would occur only when the relative humidity reaches 70% which is considered generally as the critical value for the onset of corrosion. The precise level of critical humidity varies with the type of contaminants, such as dust and salt particles, and the composition of metals. For instance, in the presence of marine salts corrosion is stimulated at lower values of relative humidity. The difference between the damp and wet environment is very narrow and it is more representative of a climatic condition rather than the magnitude of corrosion. Damp environments promote the corrosion of most metals. Water saturated with dissolved gases, such as CO2, H2S and SO2, cause severe corrosion of iron and steels, copper, nickel, silver and other non-metallic materials and alloys. For example, silver loses its luster and develops a tarnished film of sulfide on coming in contact with H2S, and copper develops tints and becomes black. In agricultural areas abundance of ammonia, particularly during the rainy seasons, subjects copper fittings to seasonal cracking and causes serious damage to water distribution systems. 2. 3 Wet Corrosion This is the most frequently observed form of atmospheric corrosion, where the water layers or pockets are formed on the metal surface, and the metal surface remains constantly in contact with water. The rate of corrosion would depend on the solubility of the corrosion product. Higher solubility means a higher rate of corrosion, because the dissolved ions increase the electrolytic conductivity. In case of alternate dry and wet conditions, the dry corrosion product film may absorb moisture from the air which increases the rate of corrosion of the metal by bringing the moisture in contact with the metal surface. Patina formation on copper, such as brochantite, and corrosion of iron and steel structures are common examples of corrosion caused by wet atmosphere.

Stonehenge :: European Europe History

Stonehenge Stonehenge, one of the great Seven Wonders of the World, but what do we really know about it. What was its purpose, how was it built and by whom. Many different answers come up when asking the question "What was the purpose of Stonehenge", some say that it was a horrid place, which the Druids used for religious sacrifice, but most others have a more positive idea. A temple of the sun, a Pagan Cathedral, or a holy sanctuary in the midst of blessed ground, or maybe a clock or even a place to Predict Eclipses. No one really knows what it was used for; this is due to a great number of facts surrounding all of these ideas. Many ideas come up when talking about why this great structure was built along with an equal amount on who built it. The Druids is the most common response because the Druids inhabited most of the area in which Stonehenge is built. The Pagans are another common answer to this age old question because of the building structure of Stonehenge how it resembles a Pagan Cathe dral. Whoever built Stonehenge, they were an extremely advanced society either on purpose or by complete fluke. Many say that because of Stonehenge's exact solar and lunar alignment. That is was the most common thought is that it was built to predict eclipses for worshiping. The following essay is going to state the facts and myths about the great Stonehenge. By the end of this essay, hopefully a solid conclusion will be found to be the most plausible answer for Stonehenges construction. The moon, it has been a sight for all over time. Back long ago little was none of the reasons for an eclipses, it was thought to be a sing from the gods. In a society which worshiped gods for all the mysteries of the world, the eclipse must have been very special. The builders of Stonehenge must have been marveled at the sight of this holy event, which happened every four years. Most likely the great Stonehenge was built to be a prediction device for the eclipse. Many people have studied Stonehenge and many have found that the stones are mathematically placed to show when and eclipse might occur. "In favor of this solution - that the Aubrey holes were used as a computer are these facts: the number 56 is the smallest number that measures the swing of the moon with an over-all accuracy of better than 3 days, and lunar cycles provide the only method of long-range eclipse prediction related to the seasons of the year.

Compare and Contrast Between the Socs and Greasers

Compare and Contrast Essay Have you ever thought once that the Greasers and Socs (from â€Å"The Outsiders†) could ever have similarities? These rich kids and deprived kids will ever have something in common. Well, you’re going to find out each ones life style, personality and society treatment. How each of them lives, how they are treated by the society and how they both feel. The Socs are filthy rich kids in the west side, making them very spoiled and all their orders are brought and done. To give an example to that is Bob Sheldon, and his gang ride with a mustang, for teenage kid this is very expensive.While, the Greasers are a group of underprivileged children who have some that work for their living, but still don’t get half of what the Socs get. Most of them have very long and greasy hair because they couldn’t afford to shave. Which shows huge difference in lifestyle. Secondly, here comes their general personality, starting with Socs. To keep up in t heir life they have to lock their emotions up inside until they are numb to their effects. They remember the feeling of anger the hit the weak ones in the society; the Greasers.They jump on the Greasers and just start hitting them and terrorizing them. Unlike the Socs, the Greasers are too emotional, they take everything serious. And when they try express it they get into serious trouble, it is why dally got arrested a over half a dozen times. Have in consideration that they both are starting to get sick of their lives and how each lives it. For example Cherry is bored of pretending not being how she is for her friends and so is Ponyboy, he pretends to be not in love with literature and music in front of his family and friends not feel weird our his friends.Here will be discussed how society treats both crews of characters. The Greasers were always known as vicious thugs in the neighborhood while they are just misunderstood kids in the wrong place and also with know one to tell them what to do. On the other hand the Socs. have to live up to a perfect vision people see of them, they have to stand up others people high expectations, Which really kills them in the inside. It reminds me when Cherry was in the movie theatre talking with Ponyboy, she didn’t hide loving bizarre music nor reading literature.She told her friends that at all, as she is a cheerleader. Finally, after comparing and contrasting Greasers and the Socs we conclude that both the Socs and the Greasers have completely different lifestyles. Surprisingly, they have something in common; not being who they are with their closest friends and also are not penchant to be judged. It shows us no mater how wealthy or poor you are you still are a normal person like everyone else, no difference in having feelings.

In the words of C.J. Heck, â€Å"We are all products of our environments.† An individual’s behavior is largely influenced by the world in which they find themselves immersed in. This dictum is exemplified in â€Å"Identity-Based Motivation: Implications for Health and Health Disparities† by Daphna Oyserman, George C. Smith and Kristen Elmore and â€Å"Stress-Related Externalizing Behavior among African American Youth: How Could Policy and Practice Transform Risk into Resilience?† by Sonya S. Brady, Willie Winston III, and Sonia E. Gockley. Both of these readings explore how people’s daily choices are influenced by the society in which they find themselves in. â€Å"Identity-Based Motivation: Implications for Health and Health Disparities† delves into the social determinants and identify-based motivation and how it relates to identity-congruence. â€Å"Stress-Related Externalizing Behavior among African American Youth: How Could Policy and Pr actice Transform Risk into Resilience?† investigates how externalizing behaviors are largely influenced by factors that children find in their homes and communities.

Prospero in William Shakespeares The Tempest Essay

Prospero in William Shakespeares The Tempest Prospero has long been read as one of Shakespeare’s most cherished and provocative protagonists. His timeless role in â€Å"The Tempest† has provided readers and critics with insights into many attributes of Shakespeare as a man, his works, and the political views that are personified in his play. The historical context of â€Å"The Tempest† is one that convincingly conveys the political views of the English people of his time, relating to the colonization of the New World, the expansion of British powers, and the domination of the indigenous peoples that was necessary for the British to thrive in the Americas. Of course, many people from the 1600’s would argue that domination of these natives†¦show more content†¦Ã¢â‚¬Å"The island’s mine by Sycorax, my mother/ which thou tak’st from me† Caliban declares, bemoaning the loss of ownership of the isle after having shown Prospero everything he needed to survive on the island. Like Caliban, the Native Americans were â€Å"willing enough to accept [European] conventions when they promoted trade, kept peace, bought land and broke the routine† (Merrell 281). The natives, like Caliban, did not mind foreign presence at first. The benefits that came out of the new relationships seemed mutual. When it became apparent that the differences in the two cultures would inevitably cause rifts leading to violence and bondage, conflicts arose and the hormonal balance was broken. â€Å"Filth as thou art† accuses Prospero of Caliban â€Å"with humane care, and lodged thee/ In mine own cell, till thou didst seek to violate/ The honor of my child† . At first, Prospero â€Å"made much of him† (Hunter 35) but he then imprisons Caliban, this â€Å"emblem of morphological ambivalence† (Brown 220) on the island and makes him into a servant. These few lines show the reader how much and how quickly Prospero’s attitude toward Caliban changed.

All My Sons By Miller Essay Example For Students

All My Sons By Miller Essay In the play All My Sons, by Arthur Miller, the word father means the personification of goodness and infallibility to Chris Keller. There was a strong relationship between Chris and his father, Joe. Everything Joe had done in his life was for Chris. His entire factory was intended for Chris once he retired. Throughout the play there was question of Joes innocence in the death of 21 pilots, who were flying planes that had parts from Joes factory. Chris strongly believed that his father played no part in those deaths and that the blame lay solely on Joes partner, Herbert Deever. At the end of the play, Chris realization that his father was guilty brings about anger and then remorse, when Joe commits suicide due to his guilty conscience. Joe has done everything in his life for his sons. Once his elder son Larry died in the war, Joe devoted his life to his younger son Chris. KELLER. Because what the hell did I work for? Thats only for you, Chris, the whole shootin-match is for you Miller, 15. Many businesses are handed down from generation to generation. Joe felt his role in life was to build a business that his son could take over once he got too old to run it. His love and hope for Chris blinded Joes ability to make a thoughtful and rational decision regarding faulty parts from his factory. This resulted in the death of the pilots. Joe completely disregarded the lives that his parts would be affecting because all he cared about was his son. The love that Joe displayed to his son was returned in the love and respect that Chris had for his father. GEORGE. But you know him. You know in your heart Joe did it. CHRIS. Lower your voice or Ill throw you out of here Miller, 46. George Deevers confrontation with Chris about his fathers guilt demonstrated Chris belief that his father was not guilty of any crime. He refused to believe that his father played a role in shipping the defective parts to the government. This only reinforced the idea that there was a strong father son bond between Joe and Chris. The moral values that were instilled in Chris blocked him from believing that his father was capable of anything else but good. These values prove to be the eventual down fall of Joe. At the end of the play Chris idealism and his moral outrage came across powerfully as he realized that his father was guilty. The solid connection between father and son was broken. As Chris struggled to understand his fathers actions, Joe still felt he had done no wrong. JOE. Nothing is bigger than the family. Im his father and hes my son. These were poignant and sad words by Joe as it showed he still had not realized the scope of the disaster he had caused. After reading the letter from Larry on the day of his death, the symbolic understanding of  the title finally comes across in dramatic sorrow when Joe fully accepts his responsibility. He feels the only recourse is to take his own life. CHRIS. Mother I didnt mean toMiller, 69. Chris felt that because he had pressured Joe into accepting his responsibility, to the universe and the people in it, he was to blame for Joes suicide. This remorse demonstrated that although Chris was deeply angered and saddened by his fathers guilt, he still loved him. Throughout the play, All My Sons, the theme of the family appeared on a number of levels. .u28f98b547fda49815ca61607115a8228 , .u28f98b547fda49815ca61607115a8228 .postImageUrl , .u28f98b547fda49815ca61607115a8228 .centered-text-area { min-height: 80px; position: relative; } .u28f98b547fda49815ca61607115a8228 , .u28f98b547fda49815ca61607115a8228:hover , .u28f98b547fda49815ca61607115a8228:visited , .u28f98b547fda49815ca61607115a8228:active { border:0!important; } .u28f98b547fda49815ca61607115a8228 .clearfix:after { content: ""; display: table; clear: both; } .u28f98b547fda49815ca61607115a8228 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u28f98b547fda49815ca61607115a8228:active , .u28f98b547fda49815ca61607115a8228:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u28f98b547fda49815ca61607115a8228 .centered-text-area { width: 100%; position: relative ; } .u28f98b547fda49815ca61607115a8228 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u28f98b547fda49815ca61607115a8228 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u28f98b547fda49815ca61607115a8228 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u28f98b547fda49815ca61607115a8228:hover .ctaButton { background-color: #34495E!important; } .u28f98b547fda49815ca61607115a8228 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u28f98b547fda49815ca61607115a8228 .u28f98b547fda49815ca61607115a8228-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u28f98b547fda49815ca61607115a8228:after { content: ""; display: block; clear: both; } READ: A revelation of love EssayChris and Joe demonstrated their dedication and love to one another through a strong bond.
