A Childish Brawl Ã¢â¬Å"SheÃ¢â¬â¢s not coming. Get them, and anyone else in the halls, to their classroom and lock the door NOW.Ã¢â¬ As those words passed through Mrs. TyndallÃ¢â¬â¢s lips, I felt myself panic.

At that moment, while I felt myself slipping from the edge, I looked around to see twenty-four pairs of eyes staring back at me. Looking into those eyes immediately closed the hole and shook me back to reality.

When I see these reports, it never seems like they could actually occur at my high school or even the school I volunteer at; it was impossible, totally preposterous. I had never been able to handle stress well, so I often overworked myself; you could ask anyone and they would agree. Except in this sudden state of panic; I felt the overflowing worry dissolve. Taking a few seconds to collect myself, I briskly led the class down the middle school hallway. The fourth graders were excited and restless, seeing Mrs. Tyndall run off and having me take them to homeroom, so they began barraging me with questions. Ã¢â¬Å"Why is Mrs. Tyndall running?Ã¢â¬ Ã¢â¬Å"Where is she going?Ã¢â¬ Ã¢â¬Å"WhatÃ¢â¬â¢s going on?Ã¢â¬ Ã¢â¬Å"WhereÃ¢â¬â¢s Mrs. Crowl?Ã¢â¬ Ã¢â¬Å"WeÃ¢â¬â¢re still going home on time, right?Ã¢â¬ They were asking the questions that were running through my head, but even though I was curious I had to get them to class. Guiding the group back into line I explained, Ã¢â¬Å"It must be something important, like an announcement, that the teachers need to do. But it s the end of the day, so the faster we get to the classroom, the faster we can go home.Ã¢â¬ With the prospect of going home in mind, the class quieted, scurrying to their classroom. Once there, I counted heads twice to be sure all of them were present, turned to lock the

During the 1970Ã¢â¬â¢s, Mexican Americans were involved in a large social movement called the Chicano movement. Corresponding with the great development of the black civil rights movement, Mexican Americans began to take part in a series of different social protests in which they demanded equal rights for themselves. Composed mainly of Mexican American students and youth, these activists focused on maintaining a pride for their culture as well as their ethnicity to fuel their political campaign. Left out of this campaign initially though were Mexican immigrants. As is made clear in the writings of David Gutierrez, since the beginning of large amounts of Mexican immigration, Mexican Americans have opposed supporting Mexican immigrants.Ã¢â¬ ¦show more contentÃ¢â¬ ¦This new identity automatically gave everyone something in common which in turn made the group of activists stronger, and more identifiable as a whole. There was also the Plan of Aztlan, where Aztlan (the area interpr eted as lost territories that Mexico surrendered to the United States after the United States Ã¢â¬â Mexico war ended in 1848) represented the symbolic territorial base of the Chicano people. The Plan of Aztlan did something for the Chicanos that contradicted their previous belief that they needed to get assimilated within the American society. If anything, Aztlan somewhat diminished and rejected any connection Chicanos had with American culture and society. Along with the changes within the movement, another momentum increasing factor was the Cisneros case ruling that Mexican Americans constituted an identifiable minority group Ã¢â¬ ¦ and are entitled to special federal assistance (Gutierrez, 186).

This concept illustrates that the present value of money on hand at time zero will be worth more in the future depending on the interest rate prevalent in the market (Besley and Brigham, 2000). In the questions given had to find out the present value of money at different interest rates as well as time periods. We used the formula S=P (1+r) ^t where Ã¢â¬Å"SÃ¢â¬ represents the future amount, Ã¢â¬Å"PÃ¢â¬ represents the present amount, Ã¢â¬Å"rÃ¢â¬ represents rate of interest and Ã¢â¬Å"tÃ¢â¬ represents time period. This formula is frequently used in order to determine the worth of money on hand in the future. In the first question we were given the interest rate, future value and the time period. By using this formula we get the present value of the amount. Question 2 gave us two options with their future value, interest rate as well as time. W e calculated the present value of both the options by the same formula as illustrated previously. Question 3 presented us with three different cash flows and we had to discount them back to get their present value. This brings us to another concept of discounted cash flow. Discounted cash flow or DCF is a natural consequence of the time value of money. It works on the principle that a dollar today is not worth the same as a dollar in future (Ehrhardt Brigham 2004). DCF analysis takes the cash flows for each period and discounts it back to time zero (t=0) i.e. today. We applied DCF concept to get present value of all future cash flow using S=P (1+r) ^t formula. Different questions in the assignment resulted in different answers but the formula, method and the reason of doing the question is same which is to calculate the present value of the amount. Hence, it has been concluded that with the help of the above mentioned formula one can easily project the present value of the future amount and can invest accordingly without being deceived.

Abstract Sidetracking has been proven to be a cost saving solution over drilling new horizontal wells to increase production from existing wells. Most problems that might be encountered when removing casing can be identified prior to beginning a lining removal job. By identifying these potential problems, the proper equipment can be used effectively to keep the job running smoothly. Technical advances in mill design such as the development of a cutting structure that effectively manages the cuttings size and is more wear resistant has increased the efficiency of the entire operation. Introduction A cost effective means to enhance production and provide for reservoir stimulation from existing platforms is to sidetrack wells from existing slots to reach new bottom hole locations. In the process of recovering these slots to facilitate the sidetrack, one or more casing strings must e removed from the existing well. Casing removal is accomplished by a combination of process such as cutting, pulling and milling. We will write a custom essay sample on Casing Milling or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In typical wells 13 3/8Ã¢â¬ and 9 5/8Ã¢â¬ casing is cut and pulled from the well. Liners from 5 ? Ã¢â¬ through 9 5. 8Ã¢â¬ may be milled to facilitate their removal. Liners and casing cemented to the surface require removal by milling long intervals which have historically been slow and at best, time consuming process. Numerous operational problems exist including difficulty in cuttings removal and potentially stuck string from Ã¢â¬Å"bird-nestingÃ¢â¬ of cuttings. With new technology available, these problems can be eliminated or minimized to make liner removal a low risk economical choice for slot recovery. This paper describes the process for recovering these platform slots and provides a review of new technology that enhances the economics of the process. Case studies will show how proper selection of the BHA, mud and mud handling system, mill design, and milling parameters make slot recovery and liner removal fast and economical. Many of the problems associated with past practices are eliminated. Milling Considerations Prior to embarking on a prolonged milling job, there are a number of issues that should be considered. These considerations can mean the difference between a project being completed on time and on budget or project running into multiple problems and costing much more than anticipated. With proper preplanning the probability of performing a good effective job will be greatly increased. Casing milling jobs are now being planned and completed at hole angles above 50 60 degrees and through long tangent sections. In the pat without the assistance of technology, these types of jobs would have a high degree of uncertainty of being completed. The result was that a section would be cut or a Whipstock would be set to facilitate a sidetrack far above the desired target depth for the completed milling job. It is important to consider the following before beginning a job: (1) Casing eccentricity, (2) Cutting removal, and (3) Pilot mill design. Casing Eccentricity. An important aspect of planning a milling job is to determine if there is any eccentricity between the casing strings. This is an important consideration for determining the proper stabilization below the pilot mill. If the inner casing to be milled is held in place with cement and with casing centralizers installed then there is a good chance that the casing strings will be concentric with one another. Therefore, the stabilizer OD of the pilot assembly should be the drift ID of the inner casing string being milled. This will ensure that the mil tracks true to the centerline of the inner casing. It will also ensure that the collars are milled completely. If the collars are not completely milled, problems can be encountered at a later time when the skinned collar is circulated to the surface. Usually this results in a plugged flow line. Should the casing not have centralizers installed and the hole angle is 30 degrees or more, it is safe to assume that the casing strings are eccentric. This will require a different strategy. A reduced OD stabilizer will be required below the mill to allow it to walk away from the ID of the casing being milled. This will prevent the mill from milling into the primary string casing. This is important because it is usually required that the primary string of casing still be testable after milling is complete. This is particularly important on wells where the hole angle is great enough that a large side load may be placed on the mill. A properly design mill with gage protection on the OD of the blades will also help protect from milling the primary string of casing. Cutting Removal Removal of cuttings during milling has a great impact on the success of a milling job. If cuttings are not removed quickly and efficiently then downtime due to bird-nesting can become a problem. Bird-nesting occurs whenever a large number of cuttings accumulate in an area in the annulus. Surface equipment, flow line configuration, and milling fluids all become important for proper cutting removal. Surface Equipment A typical arrangement of flow equipment needed to remove cuttings on the surface is as follows. Flow is routed from the bell nipple through open flow ditches to two shale shakers with primary 24 to 50 mesh screens. The fluid then exits the shale shaker through secondary 84 to 110 mesh screens. Large ditch magnets are strategically placed in the flow line and suction intakes. The magnets should be cleaned by rig personnel every half hour to remove settled swarf. Flow line Configuration To avoid flip-out of swarf in the bell nipple and BOP riser and the subsequent bird-nesting and pack-offs, it is necessary to reduce the size of the BOP and bell nipple riser from 30Ã¢â¬ to13 3/8Ã¢â¬ . This will allow a higher annular velocity to keep the BOP and BOP riser clear of swarf. It is important that the flow lines from the riser to the shakers be as large and straight as possible with all valves removed. There should not be any obstructions in the flow lines to allow a bird-nest to form. Milling fluids The selection of the proper milling fluid is critical to a successful milling job. Polymer based fluids are generally preferable because of their increased lifting capacity. In order to obtain the maximum lifting capacity of the fluid it is preferable to keep the 6 rpm viscometer reading above 45 and the plastic viscosity as low as possible.

Importance of Photosynthesis All life on Earth depends directly or indirectly on the suns energy; however plants are the only ones capable of capturing and converting solar energy into chemical energy. This is called photosynthesis. Photosynthesis is very important to survival on Earth, if it were to stop the oxygen in the atmosphere would start to deplete. There are steps for photosynthesis to take place such as capturing the energy form the sun, using the energy, and building carbohydrates. The sun is the source of energy that the plants use to perform photosynthesis. Green plants or "autotrophs" can provide their own food because they have an energy capturing substance called chlorophyll. Chlorophyll is what gives the plants the green pigment of the stems and leaves and is able to absorb light. The next step is when plants use the energy to make ATP and an energy carrying compound called NADPH. ATP is made when protons flow through a protein channel as excited electrons from chlorophyll lose energy passing through carries in the thylakoid membrane, then the energy is used to pump protons across the membrane into the thylakoid membrane. As the protons exit the channel, the thylakoid adds phosphate group to the molecule making ATP. These electrons then accept more light and then attach to NADP forming NADPH.ATP and NADPH are used to power the next step of the photosynthesis process. Building carbohydrates is the final step in the photosynthesis and it is when carbo n atoms are captured from the carbon dioxide in the air. Which are used to make organic molecules such as carbohydrates, lipids, and proteins needed for energy and growth. This process regenerates its starting molecule so that it basically is a series of steps that forms a cycle. Photosynthesis is important for all life on Earth, humans, plants, and animals. This is because the process of photosynthesis produces oxygen for us to breathe and survive, while plants need carbon dioxide. Respiration in animals, humans produces carbon dioxide and this is why plants and trees are so important to our planet. We need each other to survive and thrive. If the photosynthesis process were to abruptly stop all the oxygen in the atmosphere would deplete in a few thousand years. All life on earth depends on photosynthesis to some extent. Photosynthesis is needed for the survival and isn't a too complicated system, however is only capable through plants. We need it for food, energy and warmth. There may be only three steps but they are very important and much needed.

How to Correctly Use German Adverb Auch Sometimes the littlest words can have a big meaning. Take the German adverb auch. In its simplest form, this word means also. But it also (get it?) holds greater significance.Ã Auch can mean even. It can also be a modal particle and imply anything from I hope to Youre sure. Heres a closer look at the power behind this common, little adverb.Ã When Auch Is Accentuated This type of auch relates to the subject of the sentence and will usually be in front of a verbal group. Its meaning is also. For example:Ã Mein Sohn will jetzt auch Klavier studieren. My son now also wants to study piano. Meine Oma isst gerne Bockwurst und auch Bratwurst.My grandmother likes to eat Bockwurst and Bratwurst, as well. When Auch Is Not Accentuated This type ofÃ auch bears directly upon the elements of phrase that follow it. It usually means even. For example:Ã Auch fÃ ¼r einen fleiÃÅ¸igen SchÃ ¼ler, war dies eine groÃÅ¸e Hausaufgabe.Even for a hard working student, this was a lot of homework. Ã¯ » ¿Ihr kann auch kein Arzt helfen.Not even a doctor can help her. Take note that in the above sentences, the unaccented auch draws attention toward an accented word: fleiÃÅ¸igen or Arzt, respectively. Auch Can Express Mood An unaccented auch can also be used to indicate the mood of the speaker. In such cases, you will findÃ auch to help underline the speakerÃ¢â¬â¢s irritation or reassurance. For example:Ã Du kannst auch nie still sein!You can never be still, can you? Hast du deine Brieftasche auch nicht vergessen?I hope you didnÃ¢â¬â¢t forget your wallet. Context Is Everything Consider the following two dialogues and the meaning implied by the context. Sprecher 1: Die Freunde deines Sohnes kÃ ¶nnen gut schwimmen.Ã / Your sonÃ¢â¬â¢s friends can swim really well. Sprecher 2: Mein Sohn ist auch ein guter Schwimmer.Ã / My son is also a good swimmer.Sprecher 1: Mein Sohn treibt gerne Basketball und FuÃÅ¸ball. Er ist auch ein guter Schwimmer.Ã / My son loves playing basketball and soccer. He is also a good swimmer. Sprecher 2: Ihr Sohn ist sehr sportlich. / Your son is very athletic. As you can see, in both dialogues, the phrases with auch are practically the same, yet a different meaning is implied. Tone and context mean everything. In the first case, auch is accented and serves the subject of the sentence:Ã Sohn. In the second case, auch is unaccented and the emphasis is in on guter Schwimmer, implying that the son is, among other things, also good at swimming.

Ecnmic - Essay Example Again the prices fell during 2008, which reported a massive drop since the start of the year. These changes are due to the factors of recession that emerged during the last few years. The reasons for such change can be attributed to the demand and supply theory which states the relationship between demand and change in prices. The lower prices during 2008 are due to credit crunch that resulted in scarcity in availabilities of mortgages. The buyers could not purchase because they could not borrow money, thus, a fall in demand was seen in the housing sector. In order to boost the market, prices were lowered down to increase demand. According to certain forecasters, they will continue to remain slow because of rising inflation, unemployment and slow pace of growth. The interest rates during 2007 affected consumer spending. As in the theories of demand and supply, interest rates play a major part. Thus, the impact of interest rates on the house price will have to be established. As the interest rates rose, the number of mortgage approval also fell due to its effect on the consumerÃ¢â¬â¢s capacity to spend. When this ability decreases, the demand also decreases accordingly. It was also seen that with an increase in interest rates during 2007, a rise in sales of houses was recorded. Due to the rise in inflation, first time buyers of house felt the necessity of fund as they found themselves incapable to afford prices. Thus, with a thrust in the rate hike, the prices of house were also increased to maintain break-even as people were forced to take loan, despite the fact that interest rates were still high. Growth of real incomes: As there is a rise in an average standard of living, the demand for housing as well as for luxurious properties increased. As people in UK showed a trend to move to exclusive houses, the demand for housing increases with high prices which increased the growth of incomes
