Green Revolution History and Overview

Green Revolution History and Overview The term Green Revolution refers to the renovation of agricultural practices beginning in Mexico in the 1940s. Because of its success in producing more agricultural products there, Green Revolution technologies spread worldwide in the 1950s and 1960s, significantly increasing the number of calories produced per acre of agriculture. History and Development of the Green Revolution The beginnings of the Green Revolution are often attributed to Norman Borlaug, an American scientist interested in agriculture. In the 1940s, he began conducting research in Mexico and developed new disease resistance high-yield varieties of wheat. By combining Borlaugs wheat varieties with new mechanized agricultural technologies, Mexico was able to produce more wheat than was needed by its own citizens, leading to them becoming an exporter of wheat by the 1960s. Prior to the use of these varieties, the country was importing almost half of its wheat supply. Due to the success of the Green Revolution in Mexico, its technologies spread worldwide in the 1950s and 1960s. The United States, for instance, imported about half of its wheat in the 1940s but after using Green Revolution technologies, it became self-sufficient in the 1950s and became an exporter by the 1960s. In order to continue using Green Revolution technologies to produce more food for a growing population worldwide, the Rockefeller Foundation and the Ford Foundation, as well as many government agencies around the world funded increased research. In 1963 with the help of this funding, Mexico formed an international research institution called The International Maize and Wheat Improvement Center. Countries all over the world, in turn, benefited from the Green Revolution work conducted by Borlaug and this research institution. India, for example, was on the brink of mass famine in the early 1960s because of its rapidly growing population. Borlaug and the Ford Foundation then implemented research there and they developed a new variety of rice, IR8, that produced more grain per plant when grown with irrigation and fertilizers. Today, India is one of the worlds leading rice producers and IR8 rice usage spread throughout Asia in the decades following the rices development in India. Plant Technologies of the Green Revolution The crops developed during the Green Revolution were high yield varieties - meaning they were domesticated plants bred specifically to respond to fertilizers and produce an increased amount of grain per acre planted. The terms often used with these plants that make them successful are harvest index, photosynthate allocation, and insensitivity to day length. The harvest index refers to the above-ground weight of the plant. During the Green Revolution, plants that had the largest seeds were selected to create the most production possible. After selectively breeding these plants, they evolved to all have the characteristic of larger seeds. These larger seeds then created more grain yield and a heavier above ground weight. This larger above ground weight then led to an increased photosynthate allocation. By maximizing the seed or food portion of the plant, it was able to use photosynthesis more efficiently because the energy produced during this process went directly to the food portion of the plant. Finally, by selectively breeding plants that were not sensitive to day length, researchers like Borlaug were able to double a crop’s production because the plants were not limited to certain areas of the globe based solely on the amount of light available to them. Impacts of the Green Revolution Since fertilizers are largely what made the Green Revolution possible, they forever changed agricultural practices because the high yield varieties developed during this time cannot grow successfully without the help of fertilizers. Irrigation also played a large role in the Green Revolution and this forever changed the areas where various crops can be grown. For instance, before the Green Revolution, agriculture was severely limited to areas with a significant amount of rainfall, but by using irrigation, water can be stored and sent to drier areas, putting more land into agricultural production - thus increasing nationwide crop yields. In addition, the development of high yield varieties meant that only a few species of say, rice started being grown. In India, for example, there were about 30,000 rice varieties prior to the Green Revolution, today there are around ten - all the most productive types. By having this increased crop homogeneity though the types were more prone to disease and pests because there were not enough varieties to fight them off. In order to protect these few varieties then, pesticide use grew as well. Finally, the use of Green Revolution technologies exponentially increased the amount of food production worldwide. Places like India and China that once feared famine have not experienced it since implementing the use of IR8 rice and other food varieties. Criticism of the Green Revolution Along with the benefits gained from the Green Revolution, there have been several criticisms. The first is that the increased amount of food production has led to overpopulation worldwide. The second major criticism is that places like Africa have not significantly benefited from the Green Revolution. The major problems surrounding the use of these technologies here though are a lack of infrastructure, governmental corruption, and insecurity in nations. Despite these criticisms though, the Green Revolution has forever changed the way agriculture is conducted worldwide, benefiting the people of many nations in need of increased food production.

Atmospheric Science Essay Example for Free

Atmospheric Science Essay The first being a localised wind shear event caused by rapid cooling and descent of a column of air, the second being the build-up of ice on an aircraft as it flies through certain conditions. Each weather condition is explained in detail, with emphasis on how and why it is dangerous in the context of aviation. Two aircraft crashes, each relating to one of the weather conditions, are analysed and the meteorological factors that led to the crash examined. The official National Transport Safety Board (NTSB) documents are used as a reference. 1. 0 Introduction Meteorological conditions have an obvious influence on aviation and can be extremely hazardous in certain situations. The experience or ability of a pilot can often become irrelevant if the aircraft gets caught in a one of the many dangerous weather phenomena known to cause aviation accidents. Thunderstorms, lightning, wind shear and icing were deemed responsible for downing 4927 general aviation aircraft between 1994-2003 in the USA alone (National Transportation Safety Board, 2004). This report will focus primarily on two weather phenomena; Microbursts (Wet/Dry) and Aircraft Icing. Each meteorological condition will be explained in detail and an example of an aviation accident relating to the two types of weather condition will be analysed. 2. 0 Microburst A microburst is a rapidly descending column of air generally caused by a temperature differential associated with rain clouds. Tetsuya Fujita, a leading weather expert, defines a microburst as ‘affecting an area less then 4km in diameter’, separating a microburst from the more common ‘wind shear’, which generally affects far larger areas. Cool air descends beneath cloud cover, accelerating towards the ground before spreading linearly outward, resulting in localised high wind speeds in a radial pattern, with damage converging on the point of initial contact with the ground (see Figure. 1). For airliners and smaller aircraft alike, microbursts pose a significant threat especially at take-off and landing. Sudden and drastic variance in vertical/horizontal wind speed due to microbursts has been attributed to at least 59 general aviation crashes in the period between 1994 and 2003 (NTSB, 2004). Figure 1: The rapidly moving cold air hits the ground and spreads out horizontally. These phenomena can last anywhere between a few seconds and several minutes. Sudden wind gusts of up to 270km/h have been recorded as a direct result of microbursts. A microburst develops in three distinct phases: 1. Downburst: A body of air underneath a cloud is cooled by precipitation or virga (rain that evaporates before hitting the ground) and begins to descend. This downdraft accelerates and eventually makes contact with the ground. 2. Outburst: Having hit the ground, the air spreads out horizontally, driven by the column of air descending behind it. 3. Cushion: The air that is in contact with the ground begins to slow due to friction while the air above continues to push down and accelerate outward. Microbursts can be further categorized into ‘wet’ and ‘dry’ varieties. A wet microburst is produced as a result of warm and humid air being suddenly cooled. Precipitation or hail cools the column of air through which it is falling, resulting in a downdraft and subsequent outburst of wet air. A wet microburst is partially driven by the downward frictional force of the falling precipitation and therefore relies on a high saturation level in order to form. These microbursts are generally easy to spot as strong shafts of precipitation can be seen hitting the ground and then spreading horizontally. Dry microbursts on the other hand are generally caused by virga underneath high level cumulus clouds with little to no surface precipitation. Moisture in and underneath these clouds cools an otherwise dry and warm column of air to a point where the temperature differential creates enough negative buoyancy to begin the downburst phase. Both wet and dry microbursts depend on mid-level moisture, the adiabatic lapse rate in the sub-cloud layer and relative humidity at ground level (Wakimoto, 985). These variables are complicated to model and forecast, making microbursts extremely difficult to predict. This poses a particular risk to aircraft at lower altitudes as dry microbursts can occur in Visual Meteorological Conditions (VMC) with little to no warning, resulting in loss of control due to sudden crosswind or severe increase/decrease in lift due to either headwind of tailwind (depending on direction of flight relative to the microburst). The smaller scale of microbursts translates to much steeper wind shear gradients and therefore a much more hazardous situation then standard wind shear. 2. 1 Crash Analysis (Dry Microburst) On 24th July 2005 a single-engine Beach N35 was destroyed shortly after take-off from Salt Lake City municipal airport, Utah. All three passengers on board at the time sustained fatal injuries as a result of the crash (NTSB Incident DEN05FA114, 2005). The aircraft was found to be approximately 50kg over normal operating weight, but still within maximum parameters. According to the NTSB investigation, both the pilot and the pilot-rated passenger had checked the local weather briefing from the flight services station, and believing there to be minimal risk, proceeded to attempt take-off. Witnesses in the area reported that the plane took off without incident but stalled during climb approximately 150ft above the ground. The plane then rolled sharply, lost altitude and impacted with terrain within the aerodrome boundary. Autopsy results from the passengers ruled out any edical cause for the crash and mechanical failure was ruled out based on witness reports and examination of the wreckage. At the time of the crash, the local weather briefing included a warning for high level thunderstorms in the area; however weather data confirmed the complete absence of precipitation and minimal wind until the time of the accident. The NTSB report states that conditions were extremely favourable for the formation of dry microbursts, and goes on to state the cra sh was likely caused by ‘a dry microburst from high level thunderstorms in the area’ (NTSB Probable Cause Report DEN05FA114, 2006). Although the conditions did not seem dangerous based on weather briefings and pilot judgement, an unexpected microburst occurred in the area of the aerodrome during take-off. This likely caused a sudden increase in tailwind, stalling the aircraft and resulting in loss of height and eventual collision with the ground (See Figure 2). There is very little the pilot could have done in this situation as there was no real warning of this event occurring. This crash is a prime example of the unpredictability and hazardous nature of microbursts. Figure 2: Impact of microburst on aircraft during take-off. (Cotton, W. R, 2010). 3. 0 Aircraft Icing Icing can be a major issue for aircraft of all sizes/types and according to the NTSB, resulted in 350 general aviation accidents between 1994-2003 (NTSB, 2004). Icing will only occur in specific meteorological conditions where the atmosphere contains droplets of supercooled liquid water which will instantly form ice crystals upon contact with an aircraft. The likelihood of icing is defined quantitatively by the average droplet size, Liquid Water Content (LWC) and local atmospheric temperature. This makes icing conditions fairly straightforward to forecast given adequate weather recording systems in the area. Most aircraft are not rated to fly in known icing conditions and local weather services are obligated to warn against flying into such situations. Icing can occur in a number of ways on an aircraft. The most common is structural icing, where ice crystals form on the exterior surfaces of the aircraft. This can cause a considerable decrease in performance as the ice adds weight and inhibits the flow of air over the wing. Severe icing can also restrict movement of control surfaces and cause a pilot to lose control. Icing can also affect engine performance through carburettor or inlet icing. Icing, accelerated by the venturi effect as humid air enters the air inlet, can impede airflow and restrict the mechanical workings within the carburettor (See Figure 3). Fuel-injected systems, although not directly susceptible to carburettor icing, can still suffer from air intake icing which can slow down or completely block airflow into the engine. This can have a negative impact on engine performance and eventually lead to loss of engine function. Figure 3: Build up of Icing in Induction System (Civil Aviation Authority, 2000) According to the Terry T. Lankford in his book ‘Aircraft Icing: A Pilot’s Guide’ (1999) there are several different types of icing that can occur on an aircraft, all of which have the potential to hamper sustained flight: * Clear Ice: Supercooled liquid droplets strike the aircraft and then slowly freeze into large ice formations that can protrude out from the aircraft. * Rime Ice: Supercooled liquid droplets strike the aircraft and freeze instantly into a thin layer of ice that coats the exterior of the aircraft. Runback Ice: Droplets strike the aircraft and collect in unprotected areas of the aircraft, forming solid areas of ice that can hamper the free movement of control surfaces. * SLD Ice: Super-cooled Large Droplet ice forms when above-average size droplets strike the aircraft and freeze in a similar way to Clear Ice. This icing can occur very quickly and form large ice crystal s anywhere on the aircraft. Icing can be avoided by simply not flying into the meteorological conditions known to produce ice. However, many aircraft manufacturers include anti-icing systems that can be used in-flight in the event of unexpected icing. External surfaces can be heated by routing engine gases through ducts in the structure of the aircraft or via electrical heating. Another method is the use of ‘deicing boots’. These consist of a sealed rubber membrane stretched over the leading edge of a wing, which can inflate pneumatically in flight and break the ice off the aircraft. A more drastic method in some larger aircraft is an anti-icing fluid distribution system, which delivers fluid directly to areas where icing is occurring via tubes and spray nozzles. Within the air inlet, exhaust gases are rerouted or carburettor heat applied to minimise icing. In many aircraft, an alternate air inlet is also available in the event of complete blockage. Extreme icing can contribute to the crash of an aircraft by reducing performance to the point where sustained flight becomes impossible. Structural or carburettor icing, or in some cases a combination of the two, is a dangerous situation for any pilot if the correct actions are not taken to avoid an accident. 3. 1 Crash Analysis (Icing) On 16th of February 2007 a twin-engine Cessna 340A crashed into a snowy mountainside 3nm South-Southeast of Council Bluffs Municipal Airport, Iowa. At the time of the crash Night Instrument Meteorological conditions prevailed in the area. The pilot and three passengers sustained fatal injuries as a result of the crash. NTSB records indicate that the pilot had obtained the local weather briefing, which stated the possibility of ‘moderate icing’ and ‘moderate turbulence’ in the area. This was confirmed by other pilots and witnesses, who had reported icing below 9000ft earlier in the day. The Current Icing Potential (CIP) for the area was recorded as being a ‘70% probability of severe icing between 9000ft and 3000ft’ (NTSB Probable Cause Report CHI07FA073). As such, the aircraft likely encountered severe icing and possibly wind shear on descent, resulting in loss of control and subsequent collision with the ground. The aircraft, a 1977 Cessna 340A, was equipped with inflatable deicing boots to prevent major icing on the leading edge of the wings. However, post-crash analysis of the wreckage reported that the system had either not been deployed or was not functioning correctly during the flight prior to the crash. In this case, the pilot failed to acknowledge the potential for icing and take the proper precautions in conditions that had been determined very likely to produce severe aircraft icing. The accident occurred at night in low visibility conditions, further hampering the pilot’s ability to safely land the aircraft. It is clear that icing is at least partially responsible for the accident, with icing on the external surfaces and air inlets likely contributing to the eventual crash. The accident occurred at night in low visibility conditions, further hampering the pilot’s ability to safely land the aircraft. The accident was probably avoidable if the weather warnings had been acknowledged and the planned rote revised to minimise the risk of icing. 4. 0 Conclusion Both of these meteorological conditions, as well as all other hazardous weather phenomena, can be extremely hazardous if weather warnings are ignored or proper actions taken to minimise risk while flying. In some cases these conditions cannot be accurately predicted, and the responsibility therefore falls onto the pilot to determine whether it is safe to fly in the area.

My Moral Philosophy Essay examples -- essays research papers fc

What is a moral code? I feel that a moral code is a "unwritten code that one lives by," This code is indicating how I should live. There is not anyone watching over me judging my moral code; just I am responsible to my self for my actions. However, a moral code should always be in my head and tells me how to act in all situations. An example would be littering; is it right to throw that gum wrapper out the window of my car? No, just put it in a pocket, I can throw it out later. If you I throw that wrapper out the window I might feel what Dick Gregory (433) calls "shame"; the feeling of regret or disgrace over an action like throwing a gum wrapper out the window. The moral code would make me feel this way because I would disgrace my own moral code by throwing that wrapper out the window. I might even consider why, should I cause some one else to clean up my mess and feel shameful for causing that to happen? Another example would happen when driving in traffic. Sure, I could be that guy who doesn't let anyone in traffic and be the one yelling and honking, but why? It's not going to help me go any faster. Just relax and let some one in the traffic. Then some day when I really need to be let in traffic, the person who I let in will let me in or another person who I let in will recycle that good deed and let some one else in and in time it will get back to me. When one does a good thing it will always come back to help in time. In the end, I feel that one must treat others the way he/she would like to be treated. An example of this happened when I was on Phish tour. I lost my wallet in Albany a few years back. The kid that found it remembered me and knew he would see me at a Phish show eventually. He used my ticket for the show he was going into, but he saw me a week later and bought me a ticket for that show. In return, this past tour his car broke down so I let him jump in and ride with us. Therefore, his helping me get my wallet back helped him out directly in the long run. This is the type of person I want be, the person who helps out, and then is helped out in the end. This interpretation of a moral code reminds me of Existentialism and Jean Paul Sartre's view "that there is nothing else of man but what he makes of himself" (451), so the moral code is a part of man. There is nothing .. ...e that trip to Cape Cod, but not sit at a bar and wish it. My moral code would be to have the most pleasure in life as possible. I will not look back at college and be feeling that those were my best days. Every moment will be as enjoyable as possible, like the Epicureans. If I follow my moral code then I will have lived my life to the fullest and with the moralitys that was important to me. This includes treating others as I want to be treated, feeling that when I do something good it will come back to help me, and seeking a surplus of pleasure over pain every day.

Cultural hyrbidity Essay

The fusion of cultural and ethnic identities refers to hybridisation. Most people acknowledge that they can be affiliated with an individual culture. Banton (2000) notes that â€Å"in the contemporary UK ethnicity is becoming increasingly recognised as something everyone has†. 1 Common interests or shared values help form and develop cultural attachment’s (culture, descent, ancestry, religion, languages, food and traditional values) which in turn develops and forges ethnic identities. Migration of ethnic minorities has stirred some of the UK’s population into feeling the British national identity is under threat. Hybrid identity can be attributed to the exchange of culture through globalisation. Sheila Patterson (1965) studied first generation migrants in Brixton, London during the 1950’s. Her study involved interviews, observation and participant observation with 250 whites and 150 Afro-Caribbean’s. Patterson (1965) believes the relationship between hosts and immigrants as not fixed but evolving all the time; â€Å"Whilst adaption through socialisation and acculturation was difficult for immigrants, the host’s experience was a more passive form of acceptance. â€Å"2 Eriksen (2002) points out that â€Å"no serious scholar today believes that hereditary characteristics explain cultural variations. â€Å"3 Patterson (1965) also states â€Å"the incoming group as a whole †¦ adapts itself to permanent membership of the receiving society in certain major spheres notably economic and civil life. â€Å"4 Patterson’s final stage of adaption is assimilation, where migrants or minority groups achieve complete acceptance in society. Patterson observed that physical amalgamation may lead to distinctive features of migrant groups and that of their hosts to be lost. Patterson found the progress of the West Indian migrants in Britain was limited, â€Å"there was still opposition to the employment of West Indians by white workers. â€Å"5 Nick names and jocular references resulted in conflict. A rise in the number of West Indian landlords and the acceptance of West Indian tenants did however help alleviate housing problems. Racism existed with some shops refusing the custom of ethnic minorities due to the colour of their skin. Social relationships between migrants and hosts existed but only on a casual contact basis. Patterson (1965) noted that some of the West Indians had adopted the British way of life however, there were few inter-racial marriages. Paterson concluded â€Å"over the next decades in Britain the West Indian migrants and their children will follow in the steps of the Irish and achieve almost complete assimilation into British Society. â€Å"

Women in Reservation

On Women’s Day (March 8), India witnessed the high voltage drama over much talked Women’ Reservation Bill in the Parliament. The Women’s Reservation Bill is the most essential bill to empower women in Indian politics. According to the bill, women will enjoy 33 per cent of the reservations in the Lower House of the Parliament and Assemblies. Rajya Sabha, the Upper House of the Parliament has passed the Women’s Reservation Bill on 9 March 2010, this day in India can be termed as one of the historic days in Indian politics.Major political parties were in favor of the bill. The debate in the Upper House was interesting amidst the chaos and drama of the opposing Member of Parliaments. Stand of Political Parties: Thanks to Sonia Gandhi the Chairperson of Congress Party for the introduction of the bill on the eve of Women’s Day. And the support from the Bharatiya Janata Party (BJP) was accolade by the supporter of the bill.The stand of the BJP over the bil l is clear and the former Prime Minister of India, Atal Bihari Vajpayee was in favor of the bill. The other parties were in against of the Bill and the supporters of UPA government have threatened to withdraw their support. While talking to NDTV the soon after the bill was passed in Parliament, the Congress Chairperson, Sonia Gandhi was more confident about the bill. She also urged the need of the bill in India politics. Why the Women’s Reservation Bill?The need of the hour is women empowerment. The fact can’t be denied that still after 50 years of getting independence and self governance of Indian democracy, there is need to protect the interest of women in India. The bill will give 33 per cent of compulsory presence of women representing various parties in the Upper House of the Parliament and Assemblies. There is fear of losing elections if the women candidates are allowed to contest from various constituencies, may the right think†¦ [continues]

Stanford Prison Experiment Research Paper Example

Stanford Prison Experiment Research Paper Example Stanford Prison Experiment Paper Stanford Prison Experiment Paper The prison Experiment conducted at Stanford University in 1971 was intended to find out what would happen if average innocent people were placed in a prison environment on both sides (inmate and guard). The experiment began with a newspaper add asking for male college aged volunteers to participate in the experiment and outlined some of the things they might endure. The large number of volunteers was reduced through a series of psychological tests to find those who appeared the most stable. The researchers anticipated some psychological effects on the participants, but the results they discovered were far more intense than they had prepared for. These overwhelming effects on even the research professionals involved led to an early end to the experiment. Procedure The experiment began with an ad in the paper asking for college aged male volunteers, who would be paid fifteen dollars per day (Zimbardo, 1999). There were more than one hundred people who responded to the ad. The large number of respondents was narrowed down through a series of psychological experiments. The group was narrowed to twenty-four young men, who were determined to be mentally stable and average. The twenty-four were divided randomly into two groups by a coin toss. Half were to be prison guards and the other half was to be prison inmates. In order to set the stage for the prison to look realistic, three rooms in the basement of one of the Stanford buildings were sectioned off and the doors were replaced with doors containing bars and cell numbers. There were no windows or clocks provided to keep the prisoners from knowing the time of day (Zimbardo, 1999). Both ends of the hallway were boarded off to keep the prisoners from seeing ways to escape. The head psychologist was assigned as the prison superintendent. Other researchers participated in various capacities, but the direct supervision of the prisoners was left up to the experimental guards. A person who had spent time in prison was called in to be a consultant for treatment of the prisoners to determine how close the simulation was to a real prison setting. Methods The first day of the experiment, the people selected to be inmates were arrested from their homes by real policemen and placed in real police cars. They were taken to jail for processing and were then taken to the made-up prison. Once inside the prison the guards were given free reign within reason to treat them as prisoners. There were nine prisoners in the prison unit at all times with three on-call at their homes in case a replacement was needed. Each prisoner was strip searched and de-liced and was then given a gown with no undergarments and with an inmate number printed on it. The inmates were forced to wear hats made from panty hose to simulate shaved heads (Zimbardo, 1999). The purpose of this was to start them off with a feeling of humiliation to gain control over them. They were placed three per room and with the placement of the beds in the rooms were left little room for anything besides sitting or lying on the bed. There was a small closet designated as the solitary confinement room for the prisoners deemed as trouble makers. The restroom was down the hall, which was outside of the prison area. For this reason the prisoners were blindfolded, when they went to the restroom. Any incidents of non-compliance were met with punishments ranging from in the beginning push-ups to later much harsher punishments. At the beginning of the experiment, the guards were hesitant to be strict with them. The experiment continued with priests and lawyers coming in to interview the inmates. Results The researchers had anticipated that the prisoners and the guards would have some reactions based on their assigned roles, but the results of the actual experiment were amazing even to the people who had studied it. The people all started out to be considered relatively equal, but once they became involved in their roles personality differences became more apparent. The first day of the experiment, the inmates seemed to react in surprise to the initial treatment and complied with the directives given to them throughout the day. The second day, the prisoners began the day with a rebellion. They barricaded the guards out by placing their beds against the doors. This was met with the guards calling for reinforcements and strict punishments including using clubs to get them back under control. Following this the guards used other methods to create mistrust among the inmates to keep them from grouping together. Some of the non-compliant prisoners were placed in solitary confinement and others were forced to go without food for a period of time. The prisoners were called by their numbers instead of their names and after only a few days began addressing themselves by their numbers. This was a way of taking away their identities. After only a few days the guards and prisoners became entangled into their roles to the extent they called lawyers at the suggestion of a priest to help get them out and they went before a parole board to find out if they could get out of prison. When parole was denied some of them became seriously depressed. They had apparently forgotten they could request to leave the experiment at any time. The parents of the inmates also requested help to get their sons out of the experiment, as if they were really in prison. Some of the guards became sadistic and would use demeaning and in some cases pornographic punishments during the night when they thought the researchers were not watching. Two of the prisoners had such a strong reaction that they became distressed to the point of violent sobbing and needed medical attention. They were both released early. After the two were released, one of the on call prisoners was brought in. He did not have the opportunity to gradually become accustomed to the conditions and treatment. He went on a hunger strike shortly after becoming part of the experiment. After all attempts to get the new inmate to eat failed, he was placed in solitary for a longer period of time than anyone was supposed to be in it. The other inmates were given the choice of leaving him in solitary all night and for some special privileges, they chose to leave him in all night. The guards did eventually let him out and he was then quite distressed. The head researcher discovered he was too involved in his role as the prison superintendent, when he rearranged everything to hide the prisoners to keep them from escaping. He realized he had lost sight of the experiment and had actually become the role he was playing. When the researchers discovered how far out of control the experiment had become, they decided to end it after just six days out of the planned two week experiment. The men were all interviewed to get their views on how they were treated and what they thought had happened. Discussion Ethically the experiment would never be allowed in current society. Even prisoners are required to have some basic rights and dignified treatment. An experiment in which innocent people, even with informed consent are treated like prisoners would never be permitted. Human experimentation in any form in which there could be danger is rarely allowed. This experiment was beneficial in helping discover the effects that the prison setting could have on innocent people. It was interesting to see how the guards became involved in the roles to the point they could not separate themselves from it. They forgot that the people they were guarding were not real prisoners. The prisoners forgot their real names and became their prisoner numbers. They became depressed and to some degree almost mentally unstable. Since these people were determined to be stable before the experiment, it is easy to see how people in prison could become depressed and even suicidal if treated the way the people in the experiment were. It was enlightening to see how if people are treated poorly and stripped of their identity, they are not likely to become better people. Although this experiment could have been permanently detrimental to people’s mental health, it was beneficial to the world of psychology by providing a glimpse of what happened to people inside an institution. It showed how people were affected when their basic human rights were stripped from them.

The Fourth Dimension - Definition in Art History

The Fourth Dimension - Definition in Art History We live in a three-dimensional world and our brains are trained to see three dimensions - height, width, and depth. This was formalized thousands of years ago in the year 300 B.C. by the Alexandrian Greek philosopher, Euclid, who founded a school of mathematics, wrote a textbook called the Euclidean Elements, and is known as the father of geometry. However, several hundred years ago physicists  and mathematicians postulated a fourth dimension. Mathematically, the  fourth dimension  refers to time as another dimension  along with length, width, and depth. It  also refers to space and the space-time continuum. For some, the fourth dimension is spiritual or metaphysical. Many artists during the early 20th century, among them the Cubists, Futurists, and Surrealists, have attempted to convey the fourth dimension in their two-dimensional artwork, moving beyond the realistic representation of three-dimensions to a visual interpretation of the fourth dimension, and creating a world of infinite possibilities. Theory of Relativity The idea of time as a fourth dimension is usually attributed to the Theory of Special Relativity proposed in 1905 by the German physicist Albert Einstein (1879-1955). However, the idea that time is a dimension goes back to the 19th century, as seen in the novel The Time Machine  (1895) by British author H.G. Wells (1866-1946), wherein a scientist invents a machine that lets him travel to different eras, including the future. Although we may not be able to travel through time in a machine, scientists have more recently  discovered that time travel is, in fact, theoretically possible.   Henri Poincarà © Henri Poincarà © was a French philosopher, physicist, and mathematician who influenced both Einstein and  Pablo Picasso with his 1902 book, Science and Hypothesis. According to an article in Phaidon,   Picasso was particularly struck by Poincarà ©s advice on how to view the fourth dimension, which artists considered another spatial dimension. If you could transport yourself into it, you would see every perspective of a scene at once. But how to project these perspectives on to canvas? Picassos response to Poincarà ©s advice on how to view the fourth dimension was Cubism   viewing multiple perspectives of a subject at once. Picasso never met Poincarà © or Einstein, but their ideas transformed his art, and art thereafter. Cubism and Space Although the Cubists did not necessarily know  about Einsteins theory -   Picasso was unaware of Einstein when he created Les Demoiselles dAvignon  (1907), an early Cubist painting - they were aware of the popular idea of time travel. They also understood Non-Euclidean geometry, which the artists Albert Gleizes and Jean Metzinger discussed in their book Cubism  (1912). There they mention the German mathematician Georg Riemann (1826-1866) who developed the hypercube. Simultaneity in Cubism was one way artists illustrated their  understanding of the fourth dimension, meaning that the artist would simultaneously show  views of the same subject from different viewpoints  - views that would not normally be able to be seen together at the same time in the real world. Picassos Protocubist painting, Demoiselles DAvignon, is an example of such a painting, since it uses simultaneous fragments of the subjects as seen from different viewpoints - for example, both a profile and frontal view of the same face. Other examples of Cubist paintings showing simultaneity are Jean Metzingers Tea Time (Woman with a Teaspoon) (1911), Le Oiseau Bleu (The Blue Bird  (1912-1913), and  Robert Delaunays paintings of the Eiffel Tower behind curtains.   In this sense, the Fourth Dimension concerns the way in which two kinds of perception work together as we interact with objects or people in space. That is, to know things in real time, we must bring our memories from past time into the present. For example, when we sit down, we dont look at the chair as we lower ourselves on to it. We assume the chair will still be there when our bottoms hit the seat. Cubists painted their subjects based not on how they saw them, but on what they knew of them, from multiple perspectives. Futurism and Time Futurism, which was an offshoot of Cubism, was a movement that originated in Italy and was interested in motion, speed, and the beauty of modern life. The futurists were influenced by a new technology called chrono-photography  that showed the movement of the subject in still-photos through a sequence of frames, much like a childs flip-book. It was the precursor to film and animation. One of the first futurist paintings was  Dynamism of a Dog on a Leash  (1912), by Giacomo Balla, conveying the concept of movement and speed by blurring and repetition of the subject. Nude Descending a Staircase No. 2 (1912), by Marcel Duchamp, combines the Cubist technique of multiple views with the futurist technique of the repetition of a single figure in a sequence of steps, showing the human form in motion. Metaphysical and Spiritual Another definition for the fourth dimension is the act of perceiving (consciousness) or feeling (sensation). Artists and writers often think of the fourth dimension as the life of the mind and many early 20th century artists used ideas about the fourth dimension to explore metaphysical content.   The fourth dimension is associated with infinity and unity; the reversal of reality and unreality; time and motion; non-Euclidean geometry and space; and spirituality. Artists such as Wassily Kandinsky, Kazimir Malevich, and Piet Mondrian,  each explored those ideas in unique ways in their abstract paintings.   The fourth dimension also inspired Surrealists such as the Spanish artist Salvador Dali, whose painting, Crucifixion (Corpus Hypercubus) (1954), united a classical portrayal of Christ with a tesseract, a four-dimensional cube. Dali used the idea of the fourth dimension to illustrate the spiritual world transcending our physical universe. Conclusion Just as mathematicians and physicists explored the fourth dimension and its possibilities for alternative realities, artists were able to break away from one-point perspective and the three-dimensional reality it represented to explore those issues on their two-dimensional surfaces, creating new forms of abstract art. With new discoveries in physics and the development of computer graphics, contemporary artists continue to experiment with the concept  of dimensionality.

Heat Transfer from Steam to Water Lab Report Example | Topics and Well Written Essays - 3000 words

Heat Transfer from Steam to Water - Lab Report Example This research is derived from the basic knowledge of heat energy. The heat content of an object is reflected in the temperature behavior in the object. In the process of evaporation, it is clear that steam gives up the latent heat of vaporization to an object subjected to it, leading to condensation on the surface (Incropera and Dewitt 49). The object of condensation carries a sensible heat at the same temperature as that of the original steam. The experiment tests the pattern and rate of heat flow from steam to the object on which condensation takes place. In the steam, the latent heat of vaporization is generated instantly while condensation of the steam to water takes place. From the background of evaporation, the quantity of latent heat is between 2 to5 times more than the quantity of the sensible heat in the water after it cools (Fan 77). The data collected will be used to conduct analysis and test the hypothesis be plotting the relationship between the transfer rate and the rate of flow of the heat. The principal purpose of this project is to test the heat transfer as the steam changes to liquid water. This requires an important process of determining the quantity of heat energy consumed during the entire procedure of condensing the steam. It also aims to estimate the quantity of the latent heat used in other processes. Like in the case of boiling, heat is used to transform water into steam. This experiment compares the heat spent in heating water to its boiling point that released during condensation of the steam. Finally, this experiment evaluates the manner of heat transfer in condensation to find out if the temperature changes in the process. The equipment in this project includes a tank, pumps, heat exchanger, steam jet vacuum, surface condenser. This experiment is to compute the coefficient of heat transfer.
