actions. In the short story "Everyday Use" Alice Walker characterizes Dee by what Dee does, what Dee says, and what others say about Dee. Dee is characterized by what she does. When Dee comes home from Augusta for the first time, she steps out of the car and starts to take pictures. The pictures are of hermother and Maggie along with a cow eating grass, she also makes sure to get their house in the picture. She does this for a reason; she is hoping that when she goes back to school and shows her friends the pictures, they will feel sorry for her considering how her familyis living. At the dinner table later that night, her boyfriend comments on how their religion doesn't eat unclean meat and how he doesn't like collards. Dee, knowing exactly what he said, keeps right on eating. Dee doesn't acknowledge or respect her new religion or her boyfriend's feelings. Later, during dinner she asks if she may have the butter churn that her Uncle Buddy carved, so she can hang it on the wall in Augusta. Dee is able to go to the store and buy butter whenever she needs it, but for her family this butter churn is the only means of having butter. Later that night Dee spots two quilts that her grandmother had made. Dee asks her mother if she may have them as well. These quiltsare one thing that her mother and sister can use for warmth during the winter time. Dee,on the other hand, has heat as well as air-conditioning where she lives. Her mother thenremembers how she had already offered them to her when she went away to college, butDee refused by saying that they were old- fashioned and out of style. This is one out of many things that Dee says that characterizes her. Dee is further characterized by what she says. Before she came to visit she wrote a letter to her mother and at one point said that no matter where they choose to live, she will manage to come see them. She also wrote that when she came to visit she would never bring her friends with her. This is very insulting to her family. When she first comes home she further insults her mom and her family heritage greatly by telling them that she has changed her name to Wangero and by saying that Dee is dead. She then says "I couldn't bear it any longer, being named after the people who oppress me," meaning her family holds her down and doesn't let her live her life to the fullest. Her family, knowing Dee the best, thinks of Dee in many ways. Dee is also characterized by what others say about her. According to Dee's mother, Maggie has always thought "her sister had held life always in the palm of her hand, that 'no' is a word the world never learned to say to her," meaning Dee is stubborn and always gets her way. Her mother says that Dee will look anyone in the eye and that she doesn't know how to hesitate. Dee was known by her family for wanting nice things and having a style of her own at a young age. Dee was also known for being a very determined person. Dee's mother thinks that when Dee used to read to her and Maggie, that she would read down on them, knowing that they didn't know how to read. Her


mother says that she used to read to them without pity. When Dee wrote the letter to her mother saying that she would never bring any friends home to meet her family, Maggie said "Mama, when did Dee ever have any friends?" In conclusion, Alice Walker characterized Dee into a self-centered young woman in the short story "Everyday Use". Even though Dee has nice hair and a great figure, she is insecure because of the environment she grew up in and her origins. Dee's insecurity affects other people by putting them down, in what she does and in what she says, in order to make herself feel better. Dee thinks being mean and greedy will help her feel less insecure, but in fact it just pushes her away the people who care about her the most.

Yet, Jane flabbergasted the world with her individuality at the age of twenty. It has been scientifically proven that character traits depend on a person genes and surroundings. Jane Eyre has lived in four very different kinds of settings. Gateshead was the first home for Jane. Gatehead was the manor of her benefactress, Mrs. Reed, Jane's aunt.

English


DR. Faulkenburg


"Narrow minds think nothing right that is beyond their own capacity"


1. The essence of this quote is that a mind can think of great ideas; but if we limited our mind to our own capacity, then we will have a certain limit or view on our own thinking.


. In other words we have to open are minds to creative thinking. The thought process in a mind will be limited to us if we shut our pathway of thinking. A mind is a free sprint on its way to a beautiful road, all we have to do is focus on what is a head of us and grab it and use it in our lives more not less.


. For example if Martin Luther King did not say "I Had Dream" then today the world as we know it might be a little different I suppose. I even couldn't imagine what living in these days would have in store for me. Dr King as we all know did not have a narrow mind, he open his mind to numerous thoughts and ideas of blacks and whites coming together as one nation without any violence among them. Dr. King "dream" came true after he died, and now looks at society it has got better than ever but we can still improve.


4. To give you a metaphor (or analogy) so you can better understand what I am saying is that many people have narrow minds and that their choice but with a narrow mind comes a narrow way of thinking and you are only hurting your self in the process. An open mind takes in opportunity to understand what is happening around them to receive a better way of thinking, to open their minds to honest criticism and use it to better their minds in the future Your Query dibenzyl peroxydicarbonate matched 1 documents out of 608. 1 documents displayed. 0.77 Major Hazards (Exposure Limits) 1-11-0, http//www.inchem.org/documents/ilodb/explimit/majhaz.htm Summary 0%) CAS 144-45-8 EEC PEROXYDICARBONIC ACID, DIBENZYL ESTER (CONC. 60%) CAS 706-0-5 EEC ISOBUTYL METHYL KETONE PEROXIDE (CONC. 80%) CAS 7-1-6 EEC PEROXYCARBONIC ACID, O,O-TERT-BUTYL O-ISOPROPYL ESTER (CONC.

Assess the impact of War Communism and the New Economic Policy (NEP) on both the peasantry and proletariat in Russian society between 118 and 18.The policies of war communism and the New Economic Policy (NEP) had a great impact on both the peasantry and the proletariat. Both policies were a desperate attempt to preserve the revolution and this is greatly reflects the reasons why some groups were advantaged and why others were disadvantaged.War communism was implemented as a result of the civil war. Historians such as Maurice Dobb, E. H. Carr, and Stephen Cohen -- have interpreted war communism as a short-term expedient imposed on the Bolsheviks by the emergency demands of civil war and foreign intervention. According to this version, the system was never intended to last into normal peacetime conditions and had no special ideological significance. While this has since become the standard account, several well-informed economists writing in the 10s, such as Boris Brutzkus and Leo Pasvolsky, viewed war communism in a much more ideological light -- as an attempt to realise Marx anti-market socialist or communist utopia. The features of war communism were that peasant land was seized and then nationalised, however the peasant's control. As insufficient grain was reaching the cities the government introduced grain requisition, excess food was seized with Cheka support, it couldn't be sold for a profit. Large scale businesses were nationalised without compensation; this was extended to all business with more than ten people by 118. All private trade was abolished, and the government controlled food with ration cards and workers were paid through food rations. Workers were told when and where to work, often working up to ten hours a day, and strikes became illegal. The impact of War Communism was great on both the peasantry and the proletariat. Most peasants were prepared to burn their crops and kill their livestock rather than hand them over to the Cheka, however the dire consequences that resulted in doing this meant that many peasants did reluctantly hand them over. As the Cheka also took the seed grain an acute shortage of food and a great famine occurred during the period 10-11. Peasants resented these changes and there were many great uprisings during this period of time. This included the peasant revolution led by Antanov and the Tambok region in 11. Peasants that did not cooperate were sent to concentration camps and labour camps. The famine of 11 caused peasants to flee urban centres in search of food. The impact on the peasants were that their livelihood was destroyed they had no way of feeding their families and hence dissatisfaction with the government grew. A wave of strikes in Pertograd demanded the abolishment of grain requisitioning, freedom for peasant to run their own farm, a Soviet based government rather than a Bolshevik based government and amnesty for political prisoners.

War communism also caused dissatisfaction within the proletariat. They were unhappy about the extremely long working hours and the punishment they received simply for being late. Industrial production declined, as raw materials were not reaching the factories. Food shortages occurred and many starving workers went to the countryside to try and find food. Factories had to close down as raw materials and fuel was not reaching them. The disfavour towards the government by the proletariat was shown as membership of the proletariat to the Bolshevik party greatly declined during this period of time. The great number of illegal strikes and demonstrations caused Lenin to rethink his policy of war communism in order to preserve the revolution.The solution to War Communism was done through the New Economic Policy (NEP). The NEP partly reintroduced capitalism as it was a return to small industries. The NEP abolished requisitioning, concessions were given to the Kuklas, who were allowed to sell their surplus after paying a tax, who could rent land for limited periods of time, hire labour for cultivation and choose what they grew. It was a limited return to the cash economy with cash given rather than the ticketing system in place and private ownership of factories were allowed. Small business owners (Nepman) could purchase raw materials and sell their products but the state still had control of large scale heavy industries within its central planning regime. Lenin was quick to recognise that the peasants were very important stating that "Only the agreement with peasants can save the socialist revolution in Russia" hence the policy seemed to benefit the peasants more than the proletariat, whose lives the revolution was supposed to benefit.When firstly introduced in 11 the NEP had no impact on the peasants as it was introduced too later for the 11 sowing and severe droughts ruined crops in Central Russia and Volga area. This led to the great famine of 11. However in the period 1-1 the harvests were so good, largely due to corn seedlings from the USA, that Russia was able to export a small amount of grain. With the new conditions peasants were able to diversify and produce vegetables and fruits. As a result of this the peasants; standard of living began to improve. However agriculture still remained primitive and inefficient as peasants did not have the capital for investment, and peasants had a tendency to hoard food until prices were higher. This meant that although initial successes had been gained by 16 production levels were only equal to that of 11. Hence the NEP had initial positive impacts on the peasants, however this was not so with the proletariat.Large industry was much slower to recover from the detrimental effects of war communism as was the proletariat, who were supposed to be the beneficiaries of the October Revolution. Although major industries was owned by the government, 'Red Mangers' (former factory mangers) were employed to run nationalised industries. They were often brutal and caused hostility by the proletariat towards the government, as their methods seemed to be a reversal for what the revolution stood for. With demobilisation there was a surplus of labour in town which caused unemployment and low wages at a time of rising agricultural prices. Industrial prices remained low so there was little profit and consequently little investment to expand industry. In the early years the proletariat questioned the NEP more and more and they suffered while the peasantry prospered. The proletariat saw it as the "New Exploitation of the Proletariat".In conclusion both War Communism and the NEP had a great impact on the lives and livelihood of both the peasantry and the proletariat as described above. Whilst the NEP caused a refreshing new outlook to the peasantry after the suffering under War Communism this was not so for the proletariat. Both policies were implemented to preserve the revolution and although the initial revolution was to benefit the proletariat, the preservation of the revolution benefited the peasants.

On to the Ocean Floor A classic ophiolite sequence consists of the following layers: peridotite, gabbro, sheeted dikes, and pillow basalt (from bottom to top). The peridotite is iron and magnesium rich as well as extremely dense. The gabbro layer is produced by the partial melting from the underlying mantle. Sheeted dikes are also referred to as "feeder tubes" that carry magma upward through the chambers. The magma then erupts on the ocean floor to form the pillow basalts. Geologists have determined that it is from the ocean floor and was pushed up during the plate convergences. At Stop #1, Peridotite, I learned that the Smith River is one of the world's largest exposures to peridotite. There are several photographs depicting the Smith River as well as one showing the orange and green colors of the peridotite. Another photo shows the rough outer exterior of the peridotite. At Stop #2, Layered Gabbro, there is a photo of a sand and gravel beach as well as one of a layered rock. The rock in the picture appears similar to a sedimentary rock, but is actually a discontinuous, mixture of light and dark, layered rock. I learned that these color differentiations are produced by the olivine and pyroxene (dark layer) and the plagioclase and pyroxene (light layer).

At Stop #3, Sheeted Dikes, a photograph of dikes is displayed. This picture is across a river and one can easily see the slanted area of the dikes. This section also reemphasizes the notion that sheeted dikes are responsible for carrying magna upward through the chambers. At Stop #4, Pillow Basalt, the location is Middle Fork of the Smith and there are several pictures of exposed pillow breccia and limestone. I learned that pillow basalt results from the magna brought upward by the sheeted dikes which in turn erupts onto the ocean floor.

THE CENTRAL BUSINESS DISTRICTIntroduction The central business district (CBD) acts as the most important part of a city where the businesses are found along with the commercial activities in the centre of the city, forming what is known as the core. The CBD is a gradational fragmented zone rather than a single line that can actually be found. There are many important factors that contribute to the growth of the CBD. More purchasing power, better transportation and a larger population are preliminary conditions that have occurred as a slow process in their convergence after 1870. Other conditions that occurred over time include the economies of scale, the elimination of middlemen, the growth and location of dime stores, a need for financial exports and the vertical growth of buildings in the CBD. Changes in technology and the effects on the CBD during the later 1800's will be discussed. Street patterns and block sizes will be touched on briefly with examples of why they are important factors in the growth of the CBD. In terms of retail location, there are certain principles that will be outlined and explained. It is clear that the CBD is an extremely important part of a city as it provides its citizens with the convenience of easily accessed goods and services because of improvement in transportation and other developments in the centre of the city. (Brozowski, 00) The core of the city has undergone many changes which began as a benefit for society and for each business or industry within the district. This paper will illustrate that all the factors previously mentioned are what keep a city and a society functioning in the easiest yet most beneficial way possible.A Brief History of the CBD


Purchase your paper on Central Business District


The central business district began as a "retail-commercial district" and transformed into an "office-commercial complex" from the turn of to the middle of the century. From mid century to now, the CBD has changed again to a "convention-tourist-entertainment centre" in the larger cities. In cities that are not as large, the CBD still remains a "retail-commercial" centre. (Hartshorn, 1;p.) Between 1840 and 170, industrial and commercial industries expanded as retail spread from place to place. Retail was mixed between warehousing and finance. The industrial sector began to decrease as other sectors expanded in the downtown area by 1870 and 100 as well as wholesaling. The Industrial Revolution was an important turning point for the changes in the growth of the CBD. Important Factors in the Growth of the CBD


The Industrial Revolution was the beginning of the preliminary conditions that were brought into the CBD after 1870. More purchasing power appeared in the CBD resulting from the Industrial Revolution. There was more money available to people because of the expansion of the city after the revolution which in turn gave people the desire to buy more goods. The retail sector therefore gained more purchasing power as the industrial sector expanded and hired more people. The spending habits of urban families also show the importance of travel and transportation. (Oi, and Shuldiner, 16;p.) The second preliminary condition was the increase of better transportation. The streetcar became important with the expansion of retail in the downtown area. Again, when there are more people, there is more money to circulate and build a better CBD. With better transportation, more people are attracted to the city centre because it is more convenient for shopping in the different sections and stores in the area. Lastly, population is a huge factor in the growth of the CBD. Growth being the key word, we can say that when there is a larger population, there is growth in a community with jobs and transportation creating more money and expanding the city outwards. Immigration is the reason for the rapid expansion and population growth in cities after 1870. Immigration continues to be a factor in the extended population and expansion of cities all over the world. Some other factors that affect the growth of the CBD are the conditions that change over time but not as slow as the preliminary conditions. Economies of scale deal with production and selling of goods. The more goods that are produced means that there are more goods to be sold and eventually the products will be cheaper depending on the amounts that are selling. For example, large numbers of VCR's were produced and sold. The more that were produced, the more that were sold. When the DVD player came out, the prices of the VCRs decreased and sold and the DVD players began to sell as more were made of the new product. The prices eventually drop and sell more rapidly until people are used to the next new product. Another factor is the 'cut out' of middlemen by the manufacturers.. (Brozowski, 00) It was cheaper to buy goods from a retail store and transportation was available and easy to acquire. The growth of dime stores and there locations at the transport stops contributed in the growth of the CBD because it costs less to transport goods when the stores were located directly at the stops. Dime stores, as there name suggests, were what we call bargain shops today. They were cheap and convenient. The growth of the finance centre began with the need for financial exports. More people were needed to handle the money that entered into the CBD. With the growth of the finance centre, the growing height of buildings became a factor. The vertical growth of buildings resulted in retail pushing industry and wholesale out to the side which was beneficial for the growth of finance. Population is what was wanted from this change and the overall vertical growth produced many technology changes and positive effects on the CBD. (Hartshorn, 1;p-5) Changes in Technology and Effects on the CBD


Before 1880, buildings were constructed with dense building stone and the strength of the walls determined the height that the building would be able to reach. If a taller building was wanted, the walls would have to be constructed extremely thick to support the weight. The thick walls proved to be a waste of space in the CBD.. (Brozowski, 00) New technology was the solution to this problem and the beginning of a new city. At the beginning of the 1th century, iron girders were used as part of the industrial framing system and support for building height. In 1847, Henry Fiedler came up with a technique to make beams with cast and wrought iron sections. Rivets were used with angles and plates to make connections. (Jayachandran, 11;p) "Wrought iron was used in tension since it was twice as strong as cast iron; cast iron was used mostly in struts or columns." (Jayachandran, 11;p) The stress was no longer on the walls of the building structure but on the girders instead. The vertical growth of the city expanded and buildings could be constructed in less stable areas since the buildings were supported by iron bars. The vertical growth of the cities posed the question of transportation from the bottom to the top since stairs were not a reasonable suggestion for travelling the number of floors that were constructed within the building. This is when the invention and introduction of the elevator appeared. In the mid 1800's, the elevator was introduced as a safe means of vertical transportation in the new enhanced vertical buildings. (Brozowski, 00) The increase in height also presented a need for improvement of materials in the areas of stability and safety precautions such as fire proofing and communication because of the stronger winds that are present at higher elevations. The result of the vertical growth began with a large number of new offices that were built due to the verticalness equalling the addition of space and moved to the improvement of the concentration of employment. A problem that occurred with the vertical growth was the congestion of the people at certain times of the day and with their cars since parking was limited and more people were working and traveling around the core. Bigger freeways and multi-level parking had hoped to solve this problem but instead more cars caused more congestion so the subway became the most relevant means of transportation in the improved CBD. The vertical growth made way for improvement of new street patterns and block sizes in the CBD as well.Street Patterns and Block Sizes


These two improvements, street patterns and block sizes, are extremely important in the internal structure of the CBD. They help to form the framework for the city as do the vertical buildings for vertical calculations of the city. (Murphy, Vance and Epstein, p.) The patterns used for the streets and the sizes of each sector in the city play a huge role in the succession of the CBD. Different zones are developed in the city, a pattern which is to help guide the construction of the it and to define each area to better itself and make improvement more visible. An example of a zone pattern includes; Retail Business Uses which are subdivided beginning with food; restaurants, grocery stores, all stores dealing with all foods. Clothing; all types of clothing and fabric stores and shoe stores. Household; fireplace, ovens, sinks, baths, chairs and couches. Automotive; car and truck sales, service centers, tires and parts. Variety; typical convenient stores selling cigarettes, lottery tickets, and treats. Miscellaneous; anything from jewellery to flowers and second hand shops. (Murphy, Vance and Epstein, p.6) These classifications which are clearly subdivided are giving an idea of the land uses which help to map out the block sizes and street patterns in the CBD. Retail location is one of the zones that were just discussed when looking at land use, size and street patterns. There are other certain principles that influence the growth of the CBD as well when dealing with the retail location.Retail Location and its Principles


"More important than the size and shape of the CBD are the ways in which the district is occupied and used." (Murphy, and Vance, p.1) "The "location" of a company may not be confined to the address of the headquarters." (Grant and Nijman, 00;p5) Some businesses such as factories may be located elsewhere in the city, not just at the prime business sites. In terms of retail location, certain principles arise beginning with the trading area potential. The trade area are the shopping malls for example. The possibility of population growth in the future may have an effect on its location within the CBD as well as grocery stores which are already starting to move out of the immediate congested areas. Accessibility to the trade area is another principle that relies on location for the transport routes. If a store is located away from the transport routes, that business is not going to be as successful as the stores that are located on or nearby the routes. The growth potential for the city and the whole area is important because if that area is declining, the location of a business there might not be the best idea. Business interception is a possibility when a store is located in an area that population is in competition(Hartshorn,1p8-4). This idea can be viewed in the description of "ring interceptors"(Hartshorn,1p65). A cumulative attraction was the next factor where the shopping centers were filled with different business chains presenting the image of 'look at all the nice stuff' in the hoping that people will come and buy their products. This was followed by compatibility and then the decreasing competitive hazard of grocery stores and site economics (rent). Grocery stores were spreading out to there own locations, not in immediate congested areas as stated before and depending on the location, rent was great or horrible as was the success of a business according to location. (Brozowski, 00) Location has been stated more than once as one of the most important factors within the CBD and many changes have occurred to make location of areas more successful. The CBD has undergone many positive changes and expansions as well as deterioration which is not covered in this paper simply because the focus is merely on the positive factors, changes and effects of the CBD. Conclusion Although the CBD does cause some problems in the city, the suburbs that have formed because of these issues is just another view of city growth on the outskirts as seen in Toronto and many other large cities. Overall, the CBD is greatly appreciated and beneficial for millions. All of the factors that have been discussed throughout this paper have illustrated positive results for the final outcomes and this in turn presents the question that if the CBD didn't exist, how well off would people be? Without the CBD, life in general would not be as easy as it is today only because of the CBD and the changes that have taken place over the years to upgrade it. All of these factors dealing with the CBD have influenced our entire population and has given us all the best and easiest possible means of life. The CBD is the most beneficial invention to mankind. Without it, there wouldn't be enough time in a year to do the things people do in a day throughout the CBD.Ashlee Gowan Please note that this sample paper on Central Business District is for your review only.

The assassination of John Kennedy led to the arrival of another accidental president. Kennedy now becomes the third president killed in office after Garfield and McKinley and Texan Lyndon Johnson became the fifth accidental president in modern American history. Lyndon Johnson was a well experienced politician; this Texas cowboy started his political career in Texas policies and had earned a reputation as a successful congressman. He became the master of political manipulation and the art of power politics. He now planned to expand upon the New Frontier policies of John Kennedy; his slogan was the Great Society- an expansion of the New Frontier. This is the last major political slogan in our modern history and this slogan represents the climax of an active federal government. The Great Society was a drastic expansion of the powers of the federal government. Johnson planned a war on poverty and during his five year presidency, he became the most productive modern president. Yet he is rated only average as president; this is greatly due to his foreign policy which featured the most criticized and most expensive war in our modern history- the Vietnam War.The Johnson accomplishments are numerous and they clearly show that he worked with congress better than most modern presidents. Medicare- health insurance for the elderly- is considered one of his most important and most significant programs. He is also to be remember as one of the most effective civil rights presidents; Kennedy talked of the necessity of legislation to protect the civil rights of all Americans, especially minority Americans. Johnson took Kennedys ideas and push congress to pass the Civil Rights Act- which effectively killed Jim Crow in American society. Johnson is also to be remembered for the passage of the Voting Rights Act which ended the voting restrictions for black Americans. Johnson is also referred to as our freeway president due to the fact that most of our major freeway systems were built with federal government money during his presidency. Johnson expanded community action programs, low income housing projects and created the Office of Economic Opportunity. This became the government agency for minority programs. With pressure from his wife Lady Bird, he adopted the City Beautiful programs to plant trees and flowers where signs and billboards had stood. He also expanding upon Trumans idea of urban renewal. Effective in education reform, he was resonsible for education legislation which instituted bilingual education in schools across the nation as well as purchasing equipment for classrooms with federal funding. He created the agency for the humanities and the arts and went a long way toward the establishment of Public Television in America. Social welfare was expanded with the raising of minimum wage and the raising of social security payments; he created the welfare program and expanded unemployment benefits. Congress was well aware that an effective politician was in the white house and while this politician was crude, he really knew now to be effective with congress. Johnsons achievements also include major expansion of space projecgts, attack on disease through federal funding for medical research and development of depressed regions. The Great Society was a major expansion of the New Deal approach to government and represents the high point of government programs toward individual citizens.The Johnson programs at home were limited by his foreign policy. Johnson believed that he could use the same political manipulation in foreign policy. Johnson believed in the Truman Doctrine and in the Domino Theory; he decided to expand upon Kennedys military aid to South Vietnam. Johnson became the president of the Vietnam War; this war was his undoing. Criticism mounted as did the price tag; Americans could also watch television nightly and see that were not winning the war. This war was the undoing of Johnson and the Great Society; the war took away major funding for his Great Society programs. This war was one situation that Johnson could not control. By 168 he indicated that he felt isolated in the white house and he announced on national television that he would not seek re-election. The Johnson legacy in domestic programs is a very important one and a very detailed one, but he is still remembered today as the president of the Vietnam War- the only war that America ever lost in our entire history. The Johnson rated of average is a mixed bag; here is one of the most effective congressman/presidents, but here is one of the most criticized war presidents. In 168 the anti-Johnson votes would be very numerous; Democratic Herbert Humphrey was in the shadow of Johnson. Republican Richard Nixon was now elected president.Richard Nixon by 168 had made a remarkable political comeback. He had lost a close election to Kennedy in 160 and then he lost when he ran for governor of California. After that loss Nixon announced to the media that he was leaving public office and that they would not have Nixon to kick around anymore. But Nixon remained active behind the scenes in Republican politics and his hard work paid off when he was nominated for president in 168 and elected on the anti-Johnson votes. Insecure Richard Nixon now took over the job of president, always aware of the polls and his overall rating as president.

To achieve popularity, Nixon tried to appeal to both the conservatives and liberals in America. Actually Nixon was a conservative Republican who planned to cut back the programs of the Great Society and he did just that. The Office of Economic Opportunity, for example, was discontinued. On the other hand, many of his programs appealed to liberals and seemed to try to expand the Great Society. To say that Nixon was inconsistent as a domestic leader is correct. He is responsible for the fact that 18 year olds could vote, for an independent post office, and for major ecology programs. He also ended the draft system and pushed anticrime laws. And during his first term he took major credit for his achievements in space when a man landed on the moon.The Nixon rating is similar to the Johnson rating- both men are rated average, but there strength lies in opposite areas. While Johnson was successful at home, Nixon was successful in foreign policy. Nixon created the Nixon Doctrine which took a new approach to foreign policy. The Truman Doctrine was directed at containment of world communism; the Nixon Doctrine embraced reality in foreign policy. This reality in foreign policy involved dtente- open communications with Russia. Nixon became the first American president to visit Moscow and to take our relations with Russia in a new direction. Nixon felt that we must begin to accept world communism and deal with it in a realistic way. We see this clearly with his China diplomacy. Nixon first invited the Chinese ping pong team to visit the United States; this ping pong diplomacy led to Nixons historic trip to China and to the beginning of diplomatic relations with China. China was even allowed to participate in the United Nations. While Nixon found the Vietnam situation a difficult one to get untangled from, by 17 he had gotten us out of Vietnam. This is Vietnamization and is part of the Nixon Doctrine. Nixon also felt that the United States could not longer send massive foreign aid to western Europe, so he began the New Atlantic Charter which saw a cutback in foreign aid. Today the United States in foreign policy is clearly in the tradition of the Nixon Doctrine; the Truman Doctrine has disappeared as has much of world communism. Americans owe a great deal to Nixons leadership in foreign policy.But Nixons quest for a high rating as president as well as his insecurity and his sensitivity to criticism would be his undoing. Nixon was renominated for president in 17, while most Americans felt that Democrat George McGovern was too liberal for them. But during the campaign there was a break in at the Democratic Headquarters in the Watergate Office Building. This break in did not become an issue during the campaign and Nixon was easily re-elected. But the Watergate break in would become Nixons Watergate Scandal. A special congressional committee was established to investigate the break in and committee research revealed that the committee established to re-elected Nixon was responsible for the break in and for other illegal uses of government power such as wiretappings. Members of Nixons staff became to resign and some of them were charged with crimes. Recorded conversations from the Nixon white house made it clear that Nixon was responsible for the misuse of government powers. While Nixon continued to plead his innocence, a House committee charged him with crimes as president that would lead to his impeachment. Polls showed that Nixon would be found guilty during the trial in the Senate. So in August, 174, Richard Nixon became the first president to resign the presidency. When Nixon was elected in 17, Spiro T. Agnew was elected vice president. But before Nixon resigned, Agnew had resigned. He had been charged with crimes when he was governor of Maryland. Before the Nixon resignation, House minority leader Gerald Ford of Michigan had been appointed vice president. With the resignation of Richard Nixon, Gerald Ford now became the most accidental president of all. Richard Nixon became the third major scandal president after Grant and Harding. Watergate destroyed his presidency and his presidential rating. He was a real leader in foreign policy but he is still not rated any better than average.Gerald Ford now had a very difficult task. He must restore confidence to government and to move beyond the Watergate Scandal. Gerald Ford had earned a reputation as a hard working, honest congressman who was a former athlete and football center at the University of Michigan. But his goal of restoring confidence was hurt by his early decision to pardon Nixon for any possible crimes he may have committed as president. In addition, Ford was an uninspiring speaker and was viewed as a clumsy president when he nearly fell down all the stairs when he was exiting an airline. This image of a clumsy, dull president who had pardoned Nixon would stay with him for his two years. Ford actually accomplished little. He said that he was a moderate in domestic affairs, a fiscal conservative, and an internationalist in foreign policy. But he would be hurt by runaway inflation and a slow down in the economy. His WIN-whip inflation now- campaign was not successful and he would accomplish little in his relations with congress. Meanwhile the Nixon Doctrine was becoming reality in foreign policy as dtente with Russia continued. Ford never could overcome the Nixon shadow and the anti-Nixon and anti-Republican votes would elected Democrat Jimmy Carter in 176.James Earl Carter, Jr., now became president in 176 and would only serve one term. Carter was the only president in modern history from the deep south. He rose from being a successful peanut farmer to Georgia state politics to governor of Georgia to president in 176. His goal was to create a competent and passionate government, but he had major problems in achieve that goal. Carter was hurt by his lack of experience in national politics along with his thick southern accent which was not always accepted well by the media. While Carter developed a national energy policy, worked for civil service reform and brought about deregulation of the airlines, he was identified with rising prices (inflation) as well as the slowdown of the economy (recession). Plus he was hurt by his alcoholic brother Billy who frequently embarrassed Jimmy Carter; it was during this time that a beer was named after the presidents brother. Billy Beer had limited appeal and did not last long.Carter was also hurt by his morality in foreign policy. His deep roots in Baptist religion were evident in his foreign policy. Wilson and Carter had a similar approach to foreign policy and both had little successful as moral world leaders. Carter found that Russia did not appreciate his comments about their treatment of Russian Jews, while he had little success as a peacemaker in the Middle East. Carter was so upset when Russia invaded Afghanistan that he did not allow our Olympic athletes to participate in the Olympics in 180 in Russia. Americans were also upset that Carter did little to release the American hostages that were being held in the American embassy in Iran. Carters inability to deal with the Iran hostage crisis along with economic problems in particular inflation led to his defeat in 180 and to the election of Republican Ronald Reagan. Today Carter is rated no better than a below average president; his humanitarian work in the world has caused him to be rated a much better ex-president.Ronald Reagan became the first actor president in American History and the oldest president in American history. Reagan was a radio sport announcer who became a movie star and started in 5 films. He eventually became a conservative and was elected governor of California. Six nine days into his presidency, he was nearly killed, but he made a full recovery. With his media background, Reagan was an effective media president along with his sense of humor. But Reagan was still very much an actor as president; to make sure that his live press conferences were limited, he had helicopters in the background and because of the noise his press conferences were often cut short.Reagan wanted a smaller government and a greater America. The decline of the Great Society program was well underway. Meanwhile Reagan offered Americans a new economic program known as Reaganonics. Reaganomics involved the following 1. Taxes were cut so that consumer spending would increase, . Social welfare programs were cut back, . Defense spending was increased 5%, and 4. Foreign loans were increased. This economic program curtailed inflation and created the longest period of prosperity since World War II. Reagan was identified with this economic prosperity and his popular rating caused him to be re-elected over Democrat Walter Mondale in 184.In foreign policy Reagan wanted peace through strength. He began to move in a major way from the Truman Doctrine to the Nixon Doctrine. He had many major talks with Russian leaders, while he declared war on terrorism. While he was moving away from foreign aid for containment, his often gave a little too much power to his advisors. This was clearly seen in the Iran-contra scandal which involved selling arms to Iran and using the money to help the contra fight communism in Central America. While this scandal hurt his rating near the end of his second term, many Americans loved the prosperity of the Reagan years and wanted him nominated for a third term. But the Republicans now turned to his vice president George Bush and the Reagan popularity saw Bush elected in 188. Today experts rate Ronald Reagan an above average president due to the changes his policies brought to the economy and to his use of the media. George Bush wanted a kinder and gentler government. This man had a varied background. He was the youngest pilot in the Navy during World War II and distinguished himself well. After a college education, he entered the oil business in West Texas and then was elected to two terms in the House of Representatives from the state of Texas. He then worked in government and became Director of the CIA and under Reagan was vice president. Bush was never able to work well with congress and his achievements are home are limited. He made many promises, but they were hollow promises. He was hurt by his inability to work with congress, by a declining economy that led to a recession, to inner city violence and by increasing deficit spending.In foreign policy Bush saw the end of the Soviet Union and the major decline of world communism. Then Nixon Doctrine became American foreign policy. Bush sent troops into Panama to capture Noriega and he was the president of the successful Gulf War. The Gulf War was the best time of the Bush presidency, but it was not enough to make him a successful president or to ensure his re-election. Bush today is rated below average. The anti-Bush votes would lead to the election of William Clinton in 1.William Clinton better known as Bill Clinton entered the presidency and promised a better tomorrow. Clinton at 46 became the youngest presidency since Kennedy. Clinton was a hardworking student and was known as a capable sax player. He went from law to local politics and eventually became governor of Arkansas. Clinton continued the Nixon Doctrine in foreign policy while he still had to deal with the effects of the Gulf War. At home he tried to work with congress on a deficit reduction plan and national service program. But he failed with his major health reform and crime plan and by his second term his private life entered his presidency. Clinton had been accused for years of being a womanizer, but it was not clear that these were more than accusations. Clintons involvement with Monica Lewinsky caused the House committee to recommend his impeachment which led to a senate trial. There had never been an impeachment trial since the presidency of Andrew Johnson in the 1860s. Clintons presidency was never in doubt and the Republicans could not get /rd of the senate to vote for his impeachment. While Clintons private life hurt his presidency, his rating remained high due to declining unemployment and continued prosperity. Clinton still has not been rated by experts until he leaves office in 000, but he will be remembered for his womanizing as well as his general ineffectiveness with congress.

Stricter gun control laws could save lives because they could lower the amount of violence, lower the death rate, and get guns out of peoples hands that should not have them. Too many people today carry guns around in their everyday lives. "According to recent statistics, there are more than 00 million guns in the nation, nearly one weapon for every man, woman, and child."(Newton 46) The dictionary defines law as "a rule of conduct or procedure established by custom, agreement, or authority." The keywords in the definition are "a rule of conduct or procedure." With stricter gun control laws people would have to follow a longer strict procedure to get a gun, and this would get rid of a lot of the guns on the street. Stricter gun control laws could result in a lower crime rater. There would be fewer guns on the street and less gun-related violence, which would save lives. Armed robbery would not be as easy to do without a gun. For example, "In 16, firearms were used in 8. percent of robberies and 1.6 percent of aggravated assaults."(Klier 7) This is also true in gang-related violence because they carry guns around to protect their selves. Virginia put a law into effect in which you could only buy one gun a month, which would stop more guns from going out onto the street.And most significant is the dropin crime that has followed

enactment of limits on gun controlsales. For example, in Virginia, thenumber of murders, robberies, andaggravated assaults committed witha firearm significantly dropped after1 when the limit went intoeffect. (Klier 147)If all the states would put this law into effect the crime rate would drop significantly. Stricter gun control laws would lower the death rate. Some people argue that people would find other ways to kill, but most of the deaths come from gun-related shootings.In 16, according to the NationalCenter for Health Statistics, 4,040people died from firearms, and therewere 6,554 non-fatal gun-related injuries treated in emergency rooms around the country.(Klier 8) Please note that this sample paper on pZ is for your review only.

) History) Geology4) Composition 5) Extraction Processes6) Effects of Kyoto7) Bibliography IntroductionFor hundreds of years the oil sands have been used as a source of energy and a product of bitumen. Oil sands are deposits of bitumen and have been used in a variety of ways such as boat repairing agents by the Native Americans to a major Canadian energy source. Bitumen is a heavy black viscous oil that must be rigorously treated to convert it into an upgraded crude oil before it can be refined into gasoline and diesel fuels. Oil sands, previously known as tar sands comprise the world's largest sources of bitumen. The two largest deposits are in Alberta and Venezuela. The Alberta deposits comprise one third of the total bitumen. Oil sands are found in three places in Alberta Athabasca, Peace River and Cold Lake regions. These three areas cover a total area of nearly 141,000 km. The volume of Alberta oil sands in place is an estimated1.6 trillion barrels with an ultimate potential of 11 billion barrels and a production rate of 645,000 barrels per day . While conventional crude oil flows naturally or is pumped from the ground, oil sands must be mined or recovered using in situ (know as in-place mining). Oil sands recovery processes include extraction and separation systems to remove the bitumen from sand and water. Oil sands currently represent 40% of Albertas total oil production, and about one-third of all the oil produced in Canada. By 005, oil sands production is expected to represent 50 per cent of Canadas total crude oil output, and 10% of North American production 1. Mineable bitumen deposits are located near the surface and can be recovered by open-pit mining techniques where retraction methods are economically practical.. About two tones of oil sands must be dug up, moved and processed to produce one barrel of oil. Roughly 75 per cent of the bitumen can be recovered from sand . The recovery of denser heavy oils and the deeply buried bitumen of the oil sands require first the thinning of the oil to make it mobile, then the application of pressure to make it flow. Recovery methods are usually used for deposits more than 400 meters and consist of cyclic steam stimulation (CSS) and steam-assisted gravity drainage (SAGD). These in-situ recovery methods include thermal injection through vertical or horizontal wells, solvent injection and CO methods. This paper will discuss the Alberta oil sands with a focus on the Athabasca region. It will cover the history, geology, extraction and processing methods, and effects of the Kyoto. HistoryThe oil sands have existed for around 15 million years and remained unknown to man until around 60 years ago. They remained undiscovered because of both their burial in sand and because the remoteness of the Athabasca country remained made it greatly unexplored. The Cree and Beaver Indians were the first inhabitants of the Athabasca County and hunted the forests surrounding the Athabasca River. When European settlement began fur trading took place which later led the Europeans to be introduced to the oil sands. The natives used the oil sands as a caulking compound for repairing their birch bark canoes as well as a mosquito repellent by placing the oil sands in fires . In 171 a Native American placed the first chunk of oil sand in a non-natives hand. This man was named Henry Kelsey and he described the oil sand that gum or pitch which flows out of the banks of that river. This was the first time the now famous oil sands were mentioned in Canadian history. One hundred years later in 181 Sir John Richardson a geognostician (science of the earth) came upon the oil sands. He wrote Below this, where the Washacummow (an early name for the Clearwater), in its winding course through the valley, approaches the high- bounding hills, sections of their sides, formed by the ravines which opened into the river, enabled us to observe that they were composed of sand more or less agglutinated by bitumen, which latter hardens into slaggy mineral pitch. This sandy band, form six hundred to eight hundred feet thick, rests immediately upon yellowish-grey limestone containing many bivalve shells and orthoceratites. The dip, where it could be observed, appeared to be northward. The limestone forms the channel of the river throughout and some protions of it decaying more rapidly then others, exhibit more plainly the shells which enter vary largely into its composistion.This description shows how Richardson gave a geologic view of the oil sand as well as observing the paleontology. In 1875 John Macoun, a botanist, was the first white man to follow the outcroppings of the oil sands from north to south . Earlier accounts are of voyages down-river but none followed the outcrop from north to south. They sent Macoun on an expedition to examine the rivers draining into Lake Athabasca. He recorded his observation of water naturally washing oil out of the oil sands that is the essence of todays technology for extracting bitumen from oil sands. His main impression was that the tar wasnt mixed with mineral-matter, but the tar flowed through it. 4. The Geological Survey of Canada did more exploration of the region and came up with the prediction that under the oil-laden sands flowed a pure petroleum. They thought that a pool of oil had strained the sand beds where they rose out of the ground down river from Fort McMurry. This theory was proven wrong within 11 and 11 when the first 6 wells were drilled and there were no discoveries of these oil pockets. In 188 Dr Robert Bell established the oil sands as being in the lower Cretaceous and also reported on the possibility of hot water extraction. This hot was not attempted until 1884 by G.C. Hoffman of the Geological Survey of Canada. He reported that the bitumen separated readily from the sand. In 10 the Geological Survey of Canada assigned Dr Karl Clark and his associate Sidney M. Bair to begin research on the oil sands. They began their investigations by studying the possibilities of using oil sands as a road paving material but were soon convinced that it was more important as a potential source of crude oil 4. Clark reviewed the various separation techniques that were known, including the hot water process and decided that this process held the highest potential and would be the one which was concentrated on. Clark believed that hot water, steam and air combined with the oil sand would cause the oil to rise to the surface as a separate hydrocarbon. This theory was tested by a Calgary resident named Gordon Coulson. Coulson experimented with his wife's spin-dry washing machine and came up with the possibility of separating oil from sand by centrifuging. Although this method was efficient for primary separation it is now incorporated into the final treatment of recovered bitumen in both producing plants . Figure Abasand plant, 141.

unloaded. 14 (Provincial Archives


of Alberta, A5) The next big player in the history of the Alberta oil sands was Robert C. Fitzsimmons who was actively involved in drilling and exploration attempts at in situ production. He constructed a small model extraction plant using hot water separation which was the first to extract bitumen from the sands. In 17 the Alcan Oil Company became the International Bitumen Company. Alcan did some drilling in the 10s and was as unsuccessful as other firms. Fitzsimmons was in control of the company and concluded that mining and surface extraction would be the best commercial process4. He then decided to buy a small extraction plant and for $50 and produced 40 barrels of pure bitumen. This was the first commercially successful oil sand operation . In 1 the site of the International Bitumen Company is officially called Bitumount by Fitzsimmons. The Bitumount plant was improved by expansion, and a new refinery was constructed in 16. By late summer the Abasand Oils plant was complete and was ready to operate at a rate of 50 tons per day. The Abasand process combined a solvent extraction with hot water extraction in two stage operation. Based on the previous work at the Abasand Oil plant, it was redesigned for a capacity of 400 tons per day (Figure ). Abasand Oils began operating on a regular basis, production was quite extensive until 141 when the plant burnt down4. L.R.Champion bought out Fitzsimmons in 14 and refurnished the plant with financing help from the Alberta government. He renamed the company It was later renamed Oil Sands Ltd. This continued operations until 14 when the provincial government took over operation the later sold the Bitumount plant who sells to Can-Amera Oil Sands. Can-Amera then sells the Bitumount plant to Royalite Oil Company who closes down operations in 148 . "After years of financial jockeying and negotiations with provincial and federal government and with the support of John Howard Pew, President of Sun Oil, the Great Canadian Oil Sands group contracted in December 16 with the Bechtel Co. of San Francisco first to study and then to construct a large-scale commercial plant in the Mildred-Ruth Lakes deposit, north of Fort McMurray. In 16 a pilot plant was constructed. The main plant of Great Canadian Oil Sands was built between 164 and 167. It was authorized to produce an initial capacity of 1,000 barrels per day and officially opened in 167." In 174 Syncrude became a joint public-private venture, sponsored by Esso Resources, Gulf Canada, Canada Cities Service, Hudsons Bay Oil and Gas, and the Alberta and Canadian governments. Syncrude constructed a plant at a site near the Suncor plant north of Fort McMurray. It took 4 years to complete and was licensed to produce 15,000 barrels of oil per day. The plant opened in 148 4. Currently there are three companies working on the Athabasca oil sand and are currently involved one of the largest construction projects on the planet; The Athabasca Oil Sands Project. This is the first new fully integrated oil sands project in 5 years. When completed in early 00, it will supply 10 per cent of Canada's oil needs. It is a joint venture between Shell Canada Chevron and Western Oil Sands L.P. GeologyThe oil sands of Alberta are comprised of the Peace River, Athabasca Wabasca, Cold Lake and Llyodminister(figure 1). Jardin explains the Geology as seen in figure 5.Heavy oil sands are confined to the Mannville Group, Which is divisible into a lower and an upper unit as described by Jardine. The lower Mannville sediments are mainly comprised of non-marine sediments which are now oil reservoirs. These are seen at Peace River and Athabasca. Upper Mannville sediments contain non-marine clastics with beds of marine sands and shales. These comprise of the oil bearing sands at Wabsca and Cold Lake. Correlation chart of the areas is shown in figure 5. During the Jurassic, Western Canada was uplifted and a period of high erosion resulted. Also the Nelso and Cassiar-Omineca batholiths of the Cordilleran Region were emplaced. This uplift continued through the Cretaceous and provided a lot of detrital sediments which was combined with sediments coming from the Eastern Canadian Shield. The largest delta deposited was the Athabasca. The basal Cretaceous sands were deposited in a dominantly fluvial environment, and filled in most of the irregularities of the erosional surface only. The upper Mannville formed at the end of the lower Mannville and is represented by a short marine transgression where sands where re-worked and distributed. The remainder of the upper Mannville is dominantly non-marine through central Alberta. There are some inter-bedded marine sediments in the Lloydminister Area. Subsidence continued and this allowed the Arctic sea to advance into northern Alberta and British Columbia. This formed a layer of marine shales that make up the Clearwater and the Spirt River Formations. The upper Mannvile ends with the deposition of the partly marine Grand Rapids Sands. At the end of the Mannville the entire area began to sink. The arctic and Gulfian seas came together and formed and epicontinental ocean where the upper Cretaceous sediments were laid down . The Athabasca is the largest deposit of the heavy oils and is described well by Jardine. They occur in the basal Cretaceous McMurry sands of the Athabasca area. Sediments derived form the east were deposited in a broad basinal area situated between the Precambrian shield and a high ridge of resistand Devonian rocks that lay to the west. McMurray sediments on-lap the flanks on the western highland in the west and thin out to less the 15m. The eastern edge of the deposit adjacent to the Precambrian Shield are comprised of a series of small subsidiary basins where thin sections of the McMurray sediment accumulated. The subbasins are made by removing salt by solution of the underlying Elk Point evaporites. Deposition of the McMurray changes from continental conditions to marine conditions and this allows the McMurray to be sub-divided into an upper and lower section. The lower section is usually present in the thicker subbasins and does not contain oil. It is composed of fluvial sand and a swampy lacustrine facies. The upper unit is comprised of a fluvial facies which consists of a fluvial sheet complex, an estuarine facies which makes up most of the unit, and a marine facies. The marine facies passes upward into the Clearwater. Geographic distribution of the oil is determined by the westward thinning and disappearance of the McMurray sands. To the east there is a oil-water contact but the oil is present in a syncline. Oil saturation disappears easterly. Vertical distribution of the oil is also complex and the lowermost sands are usually barren. The richest sands are usually in the coarse grained portions and the muddier sands are more unfilled5. Geologists do not agree on how the oil sands became saturated. The two prominent theories are that the oil was formed locally or that it originated elsewhere. The second hypothesis describes why the sand particles are covered with water. The oil originated elsewhere and then flowed into a water-filled sand deposit. One problem with this theory is present flow rate data. It was thought that flow rates were on the order of m/yr but Adams shows evidence that this quick flow rate would flush the Western Canada Sedimentary Basin (WCSB) of brine within 1.6 million years. This is inconsistent with the presence of highly saline brines in the basin today. Also the modeled temperature profile is characterized by cool water recharging in the foothills and elevated heat flow near the basin margins. This poorly explains the high formation temperatures of epigenetic minerals in the deep basin. The revised model by Adams uses present day salinity profiles which are reduced to produce slower flow rates. These flow rates cannot explain the formation of the Athabasca oil sand. To explain the genesis of the Athabasca oil sands, other processes and mechanisms must be present such as tectonics, higher hydrocarbon concentrations or other mechanisms need to be included in numerical models . CompositionThe oil sands are unconsolidated grains which are not cemented together but rather held together by a grain to grain contact. It can be easily crumbled by a hand and smells like freshly lain hot asphalt. The oil sands are major constituents consist of quartz rich sand, clay, water and bitumen. The ratios which these are comprised of vary at different locations as well as the amount of bitumen is saturated in the sand. Saturation can vary from 0%-18%. More then 10% is considered rich oil sand, between 6%-10% is moderate and less then 6% is lean . The Alberta oil sands are hydrophilic (water wet) so each grain of sand is covered by a layer of water which is covered by oil. This feature allows the hot water separation method to work . Jha et al . show how the oil sands contain low molecular weights and volatile materials. The most abundant single constituent up to C-5 compounds is neopentane followed by isobutene, methane acetaldehyde, propane and isobutene. The presence of acetaldehyde shows that there is a slow maturation process. Thermolysis studies show that the maturation process is thermal. The neopentane is an end product of microbiological degradation of petroleum and/or protopetroleum. The concentration distribution volatile content shows that the oil sands all have a common origin and a similar diagenetic history. Athabasca oil sands are exposed and susceptible to aerobic oxidation which enhances the production of hydrocarbons by factors ranging from 1.1 to 50 and the rate of oxidation products, by up to 5007. "The sulfur content of a oil sand is believed to be determined largely buy the sulfur content of the undergraded precursor oil and the extent of biodegradation which involves a preferential removal of non-sulfur components." New sulfur probably is not added to the residual oil during biodegradations but its concentration is increased mainly because of the removal of other components 8. Extraction Processes MiningThe first mining practices in the Alberta oil sands occurred in the Athabasca region close to Fort McMurry. This is because the deposits have low amounts of overburden with some outcrops actually visible at the surface. This allows for recovery by surface mining was the first practical method in retrieval. Areas that are economically suitable for mining usually have an overburden of 50 feet or less 10. Surface mining is currently being used by Suncore Energy and Syncrude Limited Canada. Only 7% of the Athabasca Oil Sands deposit can be mined using the surface mining technique, as the other % of the deposit has more than 75 m of overburden. This other % will have to be mined using different mining techniques . The first step to mining is identifying area with rich amounts of bitumen by taking cores. Once this is completed the area is cleared of trees and the remaining ground cover is muskeg. This form of peat moss ranges in thicknesses of 6m to 0m and must be drained by using channels and ditches before it can be removed. This process may take two or more years . Overburden is a layer of clay, sand, and silt which lies directly above the oil sands deposit. Overburden is used to build dams and dykes around the mine and will eventually be used for refilling mined-out areas. Most mining is done by Syncrude and Suncore in the Fort McMurry region 10. Mining was first done in the 70's with large draglines that scooped up the oil sands and placed them on a conveyor belt system that led to the refining plant. This operation was slow and it was costly to maintain the equipment so the companies moved toward electric shovels . Electric shovels have buckets that hold 100 tones, and are capable of filling heavy hauler trucks with a capacity of 40 to 400 tones. The mine delivers about 400,000 tones of oil sand per day to ore preparation plants . Another refining method used is called hydro-transport where oil sand is mixed with water at the mine site then it is shipped to a plant for further processing. This method saves the cost of trucking the oil sand to the processing plant. The mined oil sand is processed to extract the bitumen from the sand using chemicals and hot water. This is done by first crushing the slurry and sending it through pipes where some bitumen is extracted. Next hot water and chemicals are added in giant separation cell where bitumen is extracted. The fine tailings (leftover sand and clay) are then pumped into a holding pond. New technologies have dropped the water temperature drastically from 15oF to 75oF and the chemical component has been dropped to a negligible amount 10. In Situ MethodsThe reserves of bitumen suitable for in situ recovery methods are almost 10 times the size of those accessible by surface mining . These new in situ projects that came on stream included BP Canada/Petro-Canada Wolf Lake, Amoco Elk Point, Dome Lindbergh, Murphy Lindbergh, and Shell Peace River. Projects use ether Cyclic Steam Stimulation (CSS) or also know as "huff and puff". The "puff" portion injects steam into the well at 00 psi which condenses into water and separates the bitumen from the sand. The condensed water is then pumped out of the well in the "huff' process 10. A new and more efficient in situ procedure used is called Steam Assisted Gravity Drainage (SAGD). SAGD has a 70% recovery rate where CSS only has a 0-5% recovery rate10 . Other advantages are that SAGD uses less steam at lower temperatures which allows SAGD to have a lower operating cost and it does not need as much specialized equipment as CSS. The SAGD process consists of two holes drilled in the oil sands with one on top of the other. The top well injects steam into the oil sand which condenses to water. The bitumen becomes fluid and it able to be pumped by out by the second well. Each well pair can produce up to 1,000 -1,500+ bbl/d and are spaced 100 - 00m apart . The Firebag site is a facility which processes the water, steam and oil. "The Firebag site consists of a well pads and associated facilities, a surface production gathering and steam distribution system, a central plant containing production treating, water recycling and steam generation facilities, and a utility corridor from Firebag to the base facility containing four connecting pipelines and a power line." (figure ). Extraction and UpgradingThe extraction process involves separating the Bitumen from the sand, clay and other materials. The oil sand is processed through apron feeders then into tumblers or conditioning drums where hot water is added to form a slurry which is less viscous. Caustic soda is then added and this which allow the bitumen to attach to air . When air is added to the slurry, it attaches to the bitumen which is then pumped to large gravity separation vessels. Here the bitumen attaches to air bubbles and rises to the top of the separation vessel and forms a bitumen-rich froth. This froth is processed through a stripper which removes the air bubbles. From there the slurry passes through a series of vibrating screens that separate and reject any rocks or clumps of clay still in the slurry and directed to two large froth storage tanks . Bitumen froth rises to the top and heavy particles are separated and removed to the bottom while the middle a gravity separation vessels is processed through a flotation system to optimize bitumen recovery. The bitumen froth is then piped into a counter-current decantation circuit where gasoline-like product called naphtha is added. This thins the bitumen froth separates the remaining solids, water and heavy asphaltenes is a three stage circuit process 14. The circuit process forms clean bitumen which is low in contaminants. It is now ready to go through a pipeline. Figure10 Western oil sands extraction plant. From http//www.westernoilsands.com/html/business/introduction.html Figure 11Extraction plant at Suncor Energy. From http//collections.ic.gc.ca/oil/index1.htmUpgrading must then be done because the bitumen from the centrifuges is not suitable for transport until it can be broken down into lighter synthetic crude oil and vacuum gas oil by increasing the hydrogen-to-carbon ratio. This is done by removing impurities such as nitrogen, sulfur and carbon . There are two main upgrading technologies; carbon removal and hydrogen conversion. Hydrogen conversion is more frequently used because it is more environmentally friendly, and eliminates the need for coke and produces more crude oil 16. This process can be seen in figure 1. The primary products produced from upgrading are naphtha, used for the manufacture of gasoline, middle distillates such as diesel, kerosene and jet fuel, and gas oils. By-products include sulfur, butane, fuel gas and coke11. KyotoKyoto has not had a significant negative impact on the Alberta oil sands. The treaty which was passed in December 00 commits Canada to reduce its green house gas emissions to 6% below the 10 levels between 008 and 01. Even though it takes 5 to 10 times the energy, area and water, to mine, process and upgrade the tar sands oil, than it does to process conventional oil there is still major development of the in the Alberta oil sands 11(Ref 6). This year Suncore has committed to invest $7.11 million to develop and maintain its production of the Athabasca and Cold Lake oil sands . Other current investments into the oil sands was French oil giant Total Fina Elf SA that has bought 41.5% of a $1 billion dollar project. These investments seem to show that Kyoto has not had a major impact on development. Suncore president and chief executive officer stated that "out capital spending plan illustrates that Suncor remains keenly focused on well managed and predictable oil sands growth." 17.Bibliography Please note that this sample paper on oil sands is for your review only.
