Pollution and The World Around Us Did you know the air we breathe on a daily basis can be harmful to our health? According to a study published in The Journal of Environmental Research Letters, Ã¢â¬Å"Air pollution kills more than 2 million people each yearÃ¢â¬ (Bradford). One of the most significant problems the world is facing today is pollution. It has affected many lives of humans and animals, and is still continuing to do so. Pollution can be fixed by people being educated on what it is doing to the lives of many people. Understanding what the sources of pollution are, realizing what illnesses it causes to animals and humans, and coming up with a solution for stopping it at its source will reduce the effects of pollution greatly. According to WebsterÃ¢â¬â¢s Dictionary, pollution is defined as, Ã¢â¬Å"substances that make land, water, and air dirty and not safe or suitable to useÃ¢â¬ (Merriam-Webster). Two very important types of pollution the world is affected by are ai r and water pollution. In many countries around the world, air pollution takes the lives of many citizens. There are many different types of air pollution, but the types that can harm people are sulfur dioxide, nitrogen, carbon monoxide, and ozone. These can come in either a gaseous or particulate form. Water pollution can harm humans, but it mainly affects the fish and other organisms that live in the bodies of water.

OthelloÃ¢â¬â¢s race does not prominently impact his demise, although Shakespeare touches upon the issue of race, the reason for OthelloÃ¢â¬â¢s demise lies somewhere else. However, the allegations of race directly lead to its tragic ending. Feelings of inadequacy and distrust without question aid in the tragedy. We will write a custom essay sample on Othello Ã¢â¬â Race and Stereotypes or any similar topic only for you Order Now The fact that OthelloÃ¢â¬â¢s skin color is important alters the interpretation of the tragedy within the play. The racism represented in Othello is not just about an instance of prejudices and prejudgments made by a crowd of people against another, but in fact has much more subtle and devastating consequences, specifically, that it is proliferated not only by the discriminatory section of society, but also by the target of this discrimination. Although Othello didnÃ¢â¬â¢t initially validate any of the stereotypical qualities that certain people labeled him with, he began adapting to them as he started to doubt himself. By coming to the assumption that he is in a racially inferior position, Othello struggled in dealing with the stereotypes appropriately, thereby only increasing his own struggle with his race. If Othello didnÃ¢â¬â¢t have such inferior complex and instead had faith within him, the conflict would never have ascended. Rather than tagging the play Othello as anti-racist or a discriminatory play, there is a substantial lesson that can be learned. From a racial perspective, the tragedy exposes the powerful outcomes that racial differences can generate when in conjunction with oneÃ¢â¬â¢s personal self-doubt. With IagoÃ¢â¬â¢s manipulations the notions of race were provoked for Brabantio, Rodrigo, and Othello, activating any suppressed racial prejudices and self-doubt. It seems obvious that Iago has strong feelings of personal inadequacy and is jealous and resentful of the love shared between Othello and Desdemona. However, IagoÃ¢â¬â¢s motive seems to be more than that. I thought his hatred was from his own personal dissatisfaction, but when he becomes lieutenant he is still unhappy and goes for the total destruction of OthelloÃ¢â¬â¢s life. So, I tried to see what it would be like to put my feet in IagoÃ¢â¬â¢s shoes, to feel his hatred and of course connect what the play is about. It then hit me that through IagoÃ¢â¬â¢s judgments Othello is Ã¢â¬Å"the MoorÃ¢â¬ and should therefore exemplify the common idea of a moor, which is not admiration, self-worth, and fortune; it is one of disconnectedness and dependency. When he says that Ã¢â¬Å"nothing can or shall content his soul/ Till he is evened with the Moor, wife for wifeÃ¢â¬ (Act 2: Scene), he means that he is satisfied until OthelloÃ¢â¬â¢s ife is made equal with his involving feelings of inadequacy and jealousy, which are all qualities fitting to a Ã¢â¬Å"moorÃ¢â¬ . Throughout the play Iago repetitively uses derogatory remarks when speaking of Othello so to encourage certain people in the play to endure racism and confirm that it was the norm. Even so, some of IagoÃ¢â¬â¢s semantics reveal his own prejudices. For example, Iago only refers to Othello as a Ã¢â¬Å"MoorÃ¢â¬ with the exception of when he refers to Othello as the Ã¢â¬Å"black OthelloÃ¢â¬ (Act 2: Scene 3). Iago hates Othello because he is Ã¢â¬Å"the MoorÃ¢â¬ yet does not symbolize the expected role of what is thought of to be a black man in these times. There is neither reason nor logic behind his hatred, but discrimination against one seldom has reason, for it is characteristically irrational thinking. Iago is a clear illustration of what racism is and will justify his irrational thoughts with anything, just as Iago contributes to Brabantio and RodrigoÃ¢â¬â¢s reasoning behind their actions and OthelloÃ¢â¬â¢s reasons for acting out on his uncertainties and self-doubt ultimately leading to his demise and an all-around tragedy.

How to Make a Cloud Chamber Although you cannot see it, background radiation is all around us. Natural (and harmless) sources of radiation include cosmic rays, radioactive decay from elements in rocks, and even radioactive decay from elements in living organisms. A cloud chamber is a simple device that allows us to see the passage of ionizing radiation. In other words, it allows for indirect observation of radiation. The device is also known as a Wilson cloud chamber, in honor of its inventor, Scottish physicist Charles Thomson Rees Wilson. Discoveries made using a cloud chamber and a related device called a bubble chamber led to the 1932 discovery of the positron, the 1936 discovery of the muon, and the 1947 discovery of the kaon. How a Cloud Chamber Works There are different types of cloud chambers. The diffusion-type cloud chamber is the easiest to construct. Basically, the device consists of a sealed container that is made warm on the top and cold on the bottom. The cloud inside the container is made of alcohol vapor (e.g., methanol, isopropyl alcohol). The warm top part of the chamber vaporizes the alcohol. The vapor cools as it falls and condenses on the cold bottom. The volume between the top and bottom is a cloud of supersaturated vapor. When an energetic charged particle (the radiation) passes through the vapor, it leaves an ionization trail. The alcohol and water molecules in the vapor are polar, so they are attracted to ionized particles. Because the vapor is supersaturated, when the molecules move closer, they condense into misty droplets that fall toward the bottom of the container. The path of the trail can be traced back to the origin of the radiation source. Make a Homemade Cloud Chamber Only a few simple materials are needed to construct a cloud chamber: Clear glass or plastic container with lid99% Isopropyl alcoholDry iceInsulated container (e.g., a foam cooler)Absorbent materialBlack paperVery bright flashlightSmall bowl of warm water A good container might be a large empty peanut butter jar. Isopropyl alcohol is available at most pharmacies as rubbing alcohol. Make sure its 99% alcohol. Methanol also works for this project, but it is much more toxic. The absorbent material could be a sponge or piece of felt. An LED flashlight works well for this project, but you can also use the flashlight on your smartphone. Youll also want your phone handy to take pictures of the tracks in the cloud chamber. Start by stuffing a piece of sponge into the bottom of the jar. You want a snug fit so it wont fall when the jar is inverted later on. If necessary, a bit of clay or gum can help stick the sponge to the jar. Avoid tape or glue, since the alcohol may dissolve it.Cut the black paper to cover the inside of the lid. Black paper eliminates reflection and is slightly absorbent. If the paper doesnt stay in place when the lid is sealed, stick it to the lid using clay or gum. Set the paper-lined lid aside for now.Pour isopropyl alcohol into the jar so that the sponge is completely saturated, but there isnt excess liquid. The easiest way to do this is to add alcohol until there is liquid and then pour the excess out.Seal the lid of the jar.In a room that can be made completely dark (e.g., a closet or bathroom without windows), pour dry ice into a cooler. Turn the jar upside down and place it lid-down onto the dry ice. Give the jar about 10 minutes to chill.Set a small dish of warm water on top of the cloud chamber (onto the bottom of the jar). The warm water heats the alcohol to form a cloud of vapor. Finally, turn off all the lights. Shine a flashlight through the side of the cloud chamber. Youll see visible tracks in the cloud as ionizing radiation enters and leaves the jar. Safety Considerations Even though isopropyl alcohol is safer than methanol, its still toxic if you drink it and its highly flammable. Keep it away from a heat source or open flame.Dry ice is cold enough to cause frostbite on contact. It should be handled using gloves. Also, dont store dry ice in a sealed container, as pressure build-up as the solid sublimates into gas can cause an explosion. Things to Try If you have a radioactive source, place it near the cloud chamber and see the effect of the increased radiation. Some everyday materials are radioactive, such as brazil nuts, bananas, clay kitty litter, and vaseline glass.A cloud chamber offers an excellent opportunity to test methods of shielding against radiation. Place different materials between your radioactive source and the cloud chamber. Examples might include a baggie of water, a piece of paper, your hand, and a sheet of metal. Which is best at shielding against radiation?Try applying a magnetic field to the cloud chamber. Positive and negative charged particles will curve in opposite directions in response to the field. Cloud Chamber Versus Bubble Chamber A bubble chamber is another type of radiation detector based on the same principle as the cloud chamber. The difference is that bubble chambers used superheated liquid rather than supersaturated vapor. A bubble chamber is made by filling a cylinder with a liquid just above its boiling point. The most common liquid is liquid hydrogen. Usually, a magnetic field is applied to the chamber so that ionizing radiation travels in a spiral path according to its speed and charge-to-mass ratio. Bubble chambers may be larger than cloud chambers and can be used to track more energetic particles.

Management - Essay Example Operations, quite differently from other major organizationÃ¢â¬â¢s functional areas such as financing, marketing, accounting etc, are more directly related to an organizationÃ¢â¬â¢s day-to-day quest of its main business (Summers, 1998, p. 1). Operational efficiency and effectiveness are critically important two terms in the contemporary business literatures, not only since they are of greater importance in strategic management but also they represent the most reliable aspects of growth and profits. This report chooses Dell Inc and describes examples of its strategic managerial and operational activities for critically analyzing the operational efficiency and effective systems to explain how they are aligned to deliver its performance objectives. Dell Inc: An Overview Started as a very small lucrative business in 1984 by Michael Dell, the company has now grown to become one of the largest computer manufacturer and multinational companies with strong strategic vision and operationa l emphasis on Ã¢â¬Ëgoing direct business modelÃ¢â¬â¢, supply chain and build to order process, virtual integration and customer focus. As Holzner (2006, p. 5) noted, Dell was placed as 25th in the list of computer manufacturers in 1990s, but eventually, its operational efficiencies and technology advantages helped the company prospered while all other 24 companies have gone out of the list. It also achieved significant place in fortune 500 companies in 1992. With more than 63,000 employees, Dell Inc operates in more than 150 countries holding considerable market share in almost all the countries it markets its products and services. With a view to eliminate middlemen markups, it has created a strategic formula of direct marketing to help it maintain substantial cost advantages (Magretta, 1999, p.193). Michael dell has long been concentrating on operation efficiencies to be attained through strategic emphasis on Ã¢â¬Ëgoing directÃ¢â¬â¢ model, effective supply chain process, v irtual integration and customization process etc. As shown in the depiction above, Dell in 2011 has been placed as third largest PC maker and marketer in the world just behind HP and Acer. Dell represented 12 percent market share in the worldwide PC market. Dell, though the recent market share and business performance has been accounted as quite below as compared to its previous yearsÃ¢â¬â¢ records, has been fostering on innovation, technology and efficient operation that in turn helped the company maintain a sustainable competitive advantage. When it comes to the business operation and operational objectives of Dell, it is very evident that the company has implemented superior managerial operation and most effective supply chain technique that have ever worked for Dell (Bozarth, 2005, p. 22). Various operational techniques such as going direct model, supply chain, customization, customer focus etc are analyzed below to review how these are deployed in Dell to achieve its organiza tional performance objectives. Going Direct Business Model For Dell Inc, the going direct marketing model has long been the
