As I lay dying - Essay Example Darl is not only a deep thinker, but very observant youth.(Wagner 1973) He immediately emerges as a unique character with what might amount to clairvoyance . Early on the reader is aware of this when Darl describes his younger brother Jewel who is behind him. He is able to discern that: â€Å"Jewel, fifteen feet behind me, looking straight ahead, steps in a single stride through the window. Still staring straight ahead, his pale eyes like wood set into his wooden face, he crosses the floor in four strides.’†(Faulkner 2000 p3) Be that as it may, Darl appears to be the sharper of the Bundrens and his philosophical nature may have confined him to a somewhat dreamy existence. While he says little, he is often times engaged in deep thought. It is indeed ironic that for a boy who has little to say, Darl conducts at least nineteen monologues throughout Faulkner’s As I Lay Dying. ‘†What you want, Darl?† Dewey Dell said, not stopping the fan, speaking up quick, keeping even him from her. He didnt answer. He just stood and looked at his dying mother, his heart too full for words†. (Faulkner 2000 p 26). It is the fear of the power associated with Darl’s clairvoyance that ultimately accounts for his family’s decision to send him to a mental institution. Darl alienates himself from the community and others fear getting too close to him. The fear is grounded in their knowledge that he will learn some ugly, hidden truth. A truth they do not wish to share with others. It is ultimately this fear that drives his family to have him committed to an institution for the mentally impaired by the end of the novel. Darl’s detachment and estrangement from his family after his mother’s death is explained by Darl in the following passage: "It is as though the space between us were time: an irrevocable quality. It is as though time, no longer running straight before us in a diminishing line, now runs

Pricing Decisions Case Study on the Springfield Noreasters Essay

Pricing Decisions Case Study on the Springfield Noreasters - Essay Example The league baseball industry is pretty bleak in the city of Springfield as of 2008. A minor league ice hockey team was about to leave the city because of unimproved revenues over the time. The Nor’easters just opened up in the city and not a single match would be played for another one and a half year by the team. Most of the minor league baseball games in the US are well attended and there are as many as 176 minor league teams in the country. The fans considered the tickets to be affordable as they could closely watch the games. The government was also investing some bucks in the industry which was evident by player development programs and team funding. The marketing director should be delighted to know that the teams which provided value entertainment often had high attendance though the teams were mediocre. This shows that the industry has a great potential for the teams willing to entertain the audience, MarketThe citizens in the Springfield city can be said to be deprive d of the baseball league games as they had to travel to neighboring cities to watch these games. The market is very dilute for the baseball teams as no baseball team for the city exists. The Falcons, a minor league ice hockey team also was planning to leave the city because of low level of sales and numerous unsold tickets.   It was found in the secondary research that only 8% of the total sample Springfield population in 2005 attended a professional baseball game in that year.

Energy Losses in Pipes

Energy Losses in Pipes ABSTRACT The objective of this lab is to associate the loss of energy in a hydraulic system with the geometry of the pipe, that contains the fluid, while it is being transported from one location to another. Special considerations were given to major and minor energy losses. Friction was taken and treated as a major loss with respect to energy, while other factors such as expansions, contractions, pipe bends, pipe fittings and obstructions were considered as minor energy losses. The design of any hydraulic systems is governed by the understanding of these relations, and this experiment is carried out with the intention proving that there is a loss of energy specifically related to these factors. [4] The DMXL Base Unit  ® in accordance with the DLM-6  ® cartridge were used to perform the experiment, using water as the medium of choice. The cartridges pressure transducers recorded the pressure differences at three locations of interest. The locations included a straight pipe secti on, a smooth 90 ° bend, and a sharp 90 ° right angle turn. For proper comparison, these results were all at the same length, of 70 mm. A total of 20 data points were tabulated, and used to calculate the loss of energy coefficients and head loss, for of all three sections. The results showed that there was a greater loss of energy with the sharp 90 ° right angle, followed by the smooth 90 ° bend and finally, the straight section had the least amount of energy loss. According to the principles of fluid mechanics, the assumption is that the highest loss of energy would correspond to the sharp 90 ° right angle bend. The results reinforced that assumption. INTRODUCTION In almost all hydraulic systems, it can be observed that there are energy losses with respect to friction and geometrical changes. The friction loss in pipes is due to the influence of the fluids viscosity near the surface of the surrounding pipe. The energy losses due to pressure changes can be seen in every part of a hydraulic system due to the expansions, contractions, bends in pipes, pipe fittings, and obstructions in the pipes. [2] This loss of energy is then transferred as heat. Frictional losses in pipework are related to: Velocity of flow Roughness of pipe surface Length of pipe Cross-sectional area of pipe Viscosity of fluid Number of pipe bends The complete acceptable pressure drop of the hydraulic system must be picked with care, as the power loss is a result of the pressure drop and system flow rate. There is an efficiency loss that must be adjusted for the cost of bigger fittings and hoses and pipework. The energy of no use is disseminated as heat energy in oil, which may prompt to cooling issues and condensing of the oil life. [1] Pressure losses in pipework will rely on the fluid flow condition. There are three particular fluid flow conditions: Laminar Flow Turbulent Flow Transition Flow As it can be seen in Figure 1, Laminar stream is the condition when the liquid particles travel easily in straight lines, the internal most liquid layer goes at the most elevated speed and the external most layer at the pipe surface doesnt move. [2] Figure 1. Laminar Flow [2] Turbulent flow has unusual and disorderly liquid molecule movements, to such an extent that a comprehensive blending of the fluid happens, as appeared in Figure 2. A turbulent flow is generally not attractive, as the flow resistance increments and in this way the hydraulic losses increment. [3] Figure 2. Turbulent Flow [3] As shown in Figure 3, with turbulence in the focal point of the pipe, and laminar flow close to the edges, the transactional flow can be seen that it is a blend of the turbulent and laminar flow. [2] Figure 3. Transitional Flow [2] Inside a pipe system, there are two sorts of losses. The first is a Major Loss and comprises of the head losses because of viscous impacts in straight fragments of pipe in the system. [5] Which is referred to as h_(L major) and the equation follows as: (1) The second sort is a Minor Loss and is a form of losses produced inside segments of the pipe system other than the straight pipes themselves. [5] Which is referred to as h_ (L minor) and the equation follows as: (2) The equation for head loss at a sudden expansion can be written as: (3) And expression for the head loss at a sudden contraction is as: (4) The head loss due to a bend can be shown by the expression as: (5) METHODOLOGY Equipment and Materials List: For the experiment, we used the Energy Losses in Hydraulic Systems cartridge on DLMX Base Unit  ®. The DLMX is a teaching equipment that can be presented as one of the absolute best designed educating device that is utilized to teach students from various different subjects like Fluid Mechanics and Heat Transfer. The equipment includes a small battery operated, base unit, into which has one of the seven different cartridges is plugged. [3] The base unit contains: Viewing panel Water reservoir Pump Controls Experimental Apparatus: According to the General Operating Instructions from the provided lab manual, the DLM-6 cartridge (Energy Losses in Hydraulic Systems)  ® was installed as shown below in Figure 4, with a filled Base Unit and powered on. The flow rate was adjusted using the knob on the Base Unit. The flow rate and corresponding differential pressure readings across the straight pipe, smooth bend and sharp bend sections appeared on the output screen. Figure 4. DLM-6 cartridge (Energy Losses in Hydraulic Systems) [3] The cartridges have the particular instrumentation required for the specific demonstration and contain an experimental representation of the topic. The base unit involves a round, clear acrylic water reservoir, mounted on a powerful vacuum shaped ABS plastic plinth, shown below in Figure (#). Under the plinth is a pump with a variable speed control, battery, flow meter, the electrical control hardware, and level sensor [6]. Figure (5) Energy Losses in Hydraulic Systems cartridge on DLMX Base Unit [3] Experimental Procedure: To commensurate our lab, we referred to Filling Pressure Transducer Tubes section as we powered on the machine. We then installed the DLM-6 cartridge (Energy Losses in Hydraulic Systems)  ® into the Base Unit filled with water and ensured that all pressure readings are at zero flow rate. We can read the flow rate and pressure drop at that moment is given if we scrolled down on the display on the machine. Next, we checked for the possible maximum flow rate. From there we were able to get an estimate of the increment differences needed for each reading. The flow rate was set to ~ 1 L/min and increased in approximately equal increments until the maximum flow rate was achieved. And then the pressure drop was obtained and recorded. Steps were repeated until Experimental DLMX  ® data table is completed. RESULTS Table 1 shows the data points recorded from different runs of fluid flowing through ΆP Straight, ΆP Smooth, and ΆP RA Bend. Table 1. Data points recorded from the experiment.

DISCUSSION In order to obtain the pressure difference in a circular pipe it is possible to reduce the energy equation as follows. (10) (11) Where, à ¡Ã¢â‚¬ËœÃ‚ ­ = Density of fluid, g = gravity, h = height, P = pressure, V = average velocity, z = elevation and This reduction is applicable when the cross-sectional area as well as the elevation are equal. For circular channels, the head loss due to flow can be obtained using the equation below. (12) Where, f = Stanton friction factor, L = length of circular channel, D = diameter, V = average velocity and g = gravity. In contrast to circular channels, the energy equation can also be used to obtain the pressure difference in noncircular channels as follows. (13) However, in noncircular channels, the head loss due to flow can be obtained using the equation (14) Where, (15) Moreover, the friction factor for non-circular channels is a function of the roughness factor divided by the hydraulic radius and the Reynolds number. (16) For noncircular channels, the Reynolds number is also calculated using the hydraulic diameter as follows. (17) It is possible to measure pressure losses arising from fittings to the piping system using the DLMX fluid mechanics cartridge fitted with differential pressure transducers that connected to pressure taps which registers the difference in pressure related to the flow. The pressure difference can be evaluated using the energy equation that includes major friction losses due to fittings on the piping system as follows. (18) For the cartridge, the energy balance equation begins as follows below. (19) Considering the cartridge as a closed system the energy balance equation reduces as follows below. (20) Physically, represents the pressure losses per unit mass of water in the cartridge. On the other hand, represents the differences in pressure at the three points of interest associated with flow. The hierarchy of pressure difference starting from the least pressure difference to the highest is as follows below. The pressure drop at the right-angled bend can be calculated using from the energy balance equation below. (21) Because there is no change in diameter throughout the length of the bend, no change in elevation, as well as no change in elevation, the energy balance equation reduces to. (22) The loss coefficient is a dimensionless coefficient derived from dividing the head loss by as follows below. (23) Therefore, Finally, to calculate the required pressure losses in the bend the equation above reduces as follows below. (24) At the straight portion of the pipe, the pressure drop equation reduces as follows below. (25) Where f=the friction coefficient, D=diameter of the pipe and L= the length of the pipe. In order to find the length of straight pipe that would be sufficient to generate the same amount of pressure drop at the right-angled bend the pressure drops have to be made equal as follows below. (26) The length of the pipe then reduces to the formula below. (27) It is possible to determine the loss coefficient graphically from the experimental values by creating a graph of the head loss vs dynamic head. (28) Where and = dynamic head, the loss coefficient Figure 6. Head loss vs Dynamic Head CONCLUSION The goals of this lab was to measure the head losses through straight, smooth, and sharp- bend pipe fittings and then use these measurements to estimate the loss of energy coefficients for each transition or fitting. For the experiment, the DML-6  ® cartridge (Energy Losses in Hydraulic Systems) was used with the DLMX Base Unit  ®, using water as the fluid of choice. The flow rate and corresponding differential pressure readings across the straight pipe, smooth bend and sharp bend sections were all recorded. A total of 20 data points were collected. The collected datas were used to calculate the head losses and loss of energy coefficients for all three sections. The results show that the pressure difference in the right-angle bend is higher than smooth bend, and pressure difference in smooth is higher than the straight bend pipes. Also, the average head loss of a right-angle pipe, 1.633, is certainly higher than average head loss of the smooth, 2.144, and straight, 1.63 3. Furthermore, the average loss coefficient of right angle pipe, 16.84078, was also higher than smooth, 10.988725, and straight, 0.13513, pipes. Uncertainty analysis indicate that one possible source of error came from the pressure readings. The pressure readings at the reference point for each component and each flow was some value greater than zero, but the problem with this was that all the reference point readings should have been zero regardless of the set up. The reason for this difference is still unknown, however the doubt is that there was a problem with the machines manometer. The lesson learned with this experiment was the energy losses in pipes due to different fittings. The experiment was quite interesting, yet this hands-on approach lesson will help us succeed in the real engineering world as well. REFERENCES [1] Bruce Roy, Munson, T. H. Okiishi and Donald F.

APPENDIX B Names Tasks Hours Rigoberto Aguilera Maaz Khan Esther Ndichu Trang Pham Prabhjit Singh APPENDIX C It should be noted that when using Bernoullis equation, one must take into consideration the height of a pipe. The data that was used in the calculations was processed without that consideration. The manufacturer of the unit explains that the pressure transducers inside the DLM-6  ® cartridge do not measure hydrostatic pressures between the taps, when the tubes are filled with water. As it can be seen in the image below the device is filled with water, but the water is not in motion. The levels of the manometer tubes are the same, regardless of the vertical setup. With the same concept in mind, it is clear to see that the pressure transducers will also fail to measure any pressure change with respect to gravity.

Existentialism in Catcher in the Rye Essays -- Catcher Rye Essays

Existentialism in Catcher in the Rye The Catcher in the Rye creates an existentialist out of Holden Caulfield by giving him a strong personal opinion, a different sense of view, and isolation. Holden's individuality and his different way of thinking creates within him an Existentialist that refuses to accept weakness but holds sympathy for the weak and vulnerable. The basis for these beliefs lies within the most commonly identifiable theme of existentialism, which states that the philosophy stresses the concrete individual existence along with the individual freedom and choice. It also stands on the idea of moral individualism, in which one must choose his own way without the aid of universal, objective standards. His views also coincide with those of many famous people who have shared the same ideas, including Pascal, Kierkegaard, and Nietzsche. The Catcher in the Rye demonstrates existentialism by having the main character, Holden Caulfield, isolate himself from a world full of "p...

Finance and banking Essay

Chapter 1 1. Has the inflation rate in Canada increased or decreased in the past few years? What about interest rates? R/. The inflation rate of CAnada is low. The inflation rate was at 1.10 % in August. And the interest rate was declining. In one news said that on 1915 until 2013, the Canada’s inflation rate 3.2% reaching an all time high of 21.6% in June of 1920 and got a record low at -17.8% in June of 1921. 2. If history repeats itself and we see a decline in the rate of money growth, what might you expect to happen to A. Real output – is going down B. the inflation rate, and – is going down C. Interest rates – is going down All are going to fall. 3. When was the most recent recession? According to the National Bureau of Economic Research (the official arbiter of U.S. recessions), there were 10 recessions between 1948 and 2011. And the recent recession started in December 2007 and finished in June 2009. 4. When interest rates fall, how might you change your economic behaviour? I will buy a car and house because the cost of them would fall. I think when the rates fall is good spend more money for get good properties and the future I can duplicate what I spend. 5. Can you think of any financial innovation in the past ten years that has affect you personally? Has it made you better off or worse off? Why? I think all the inventions that the government made, for example the subway and trains. This made me better off, because for me I feel more comfortable with the transportation and for all the population, this made more opportunities for get a job. 6. Is everybody worse off when interest rates rise? When net rest rates rise is not worse off, but for the people who borrow for get a house or a car would be worse off for them, because will cost more to finance their purchase. 7. What is the basic activity of banks? Store money Storing money for customers is the most classic of banking activities. Traditional banks, credit unions and savings institutions offer this service. Customers use bank accounts, such as checking or regular savings accounts, because most provide safe locations to store deposited money that is FDIC-insured, or protected by the Federal Deposit Insurance Corporation. Facilitate Payments Banks and financial institutions enable their customers to pay others. Customers are given checks, both paper and electronic, and other payment tools, such as debit cards. A customer is able to write a check or make a payment to an outside vendor, such as a grocery store, electricity company or other outside individual, with one of their designated payment tools. The financial institution sends money from the customer’s account to their designated payee. Loan Money Lending money allows a bank or financial institution to earn money, according to the FDIC website. This for-profit service involves the bank lending a sum of money to a customer and then charging interest as the loaned amount is repaid back to the institution. Loans are used to purchase or lease automobiles, buy homes, refinance mortgages, perform home repairs and other expensive projects. 12.How does a fall in the value of the pound sterling affect British consumers? R/. This will makes the foreign goods expensive and the British are not going to buy this foreign goods because they are going to choose for the cheaper one. 13.How does an increase in the value of the pound sterding affect American businesses? R/. For American business will be easier for sell their goods and they can sell it in the United States or abroad. 14.When the dollar is worth more in relation to currencies of other countries, are you more likely to buy American-made or foreign-made jean ? Are U.S.companies that make jeans happier when the dollar is strong or when it is weak? What about American company that is in the business of importing jeans into the United States? R/. In the mid-to late 1970s and in the late 1980s and early 1990s, the value of the dollar was low, making travel abroad relatively more expensive; thus it was a good time to vacation in the United States and see the Grand Canyon. With the rise in the dollar’s value in the early 1980s, travel abroad became relatively cheaper, making it a good time to visit the Tower of London. Chapter 2 1.Why is a share of IBM common stocks an asset for its owner and a liability for IBM? The share of IBM stock is an asset for its owner because it entitles the owner to a share of the earnings and assets of IBM. The share is a liability for IBM because it is a claim on its earnings and assets by the owner of the share. 2.If I can buy a car today for $5000and it is worth $10,OOO in extra income next year to me because it enables me to get a job as a traveling  anvil seller, Should I take out a loan from Larry the loan Shark at a 90% interest rate if no one else will give me a loan? Will I be better or worse off as a result of taking out this loan? Can you make a case for legalizing loan-sharking? I should take out a loan from Larry, if I make a case for legalizing that would give problem and can affect the bank. It’s not good make a case. 3.Some economists suspect that one of the reasons that economies in developing countries so slowly is that they do not have well-developed financial markets. Does this argument make sense? Yes, because the absence of financial markets means that funds cannot be channeled to people who have the most productive use for them. Entrepreneurs then cannot acquire funds to set up businesses that would help the economy grow rapidly. 10. If you are an employer, what kinds of moral hazard problems might you worry about with your employees? R/. I would be concerned that they have their own responsibilities and they might steal things or do not good behaviour. 11.If there were asymetwmthe information that a borrower and a lender had, could there stiIl be a moral hazard problem? Yes, because even if you know that a borrower is taking actions that might jeopardize paying off the loan, you must still stop the borrower from doing so. Because that may be costly, you may not spend the time and effort to reduce moral hazard, and so the problem of moral hazard still exists. 14.How does risk sharing benefit both financial intermediaries and private investors? Risk sharing benefits and financial intermediaries are able to earn a spread. Investors benefit are able to invest in good diversified portfolio.

Plant Based Diet Essay

When I was growing up I was taught how to hunt, fish and trap animals for food as well as being fed an omnivorous diet, but today I have found that I no longer need animals in my diet. The Vegetarian Times recently found that out of the 311 million people in the US, 7.3 million eat a vegetarian based diet and 22.8 million eat a vegetarian inclined diet. Over the past century people have begun looking into the health implications of plant based diets as a way of improving their health and increase their longevity. This research paper is intended to inform the reader of the nutrients required by a US adult, ages 18-35, and prove that a plant based diet meets those nutrient requirements. This journey began for myself over a year ago and while continue for decades to come while plant based diets began with the birth of mankind and will continue as long as we continue to live. Definitions associated with plant based diets Vegetarianism has been around since the beginning of mankind, however as society has progressed so have plant based diets. Today the term plant based diet can be confusing because of the varying levels of animal consumption in an individual’s diet. The first definitions that will be examined are plant based foods and an omnivorous diet. Plant based foods are those foods which consist of â€Å"†¦fruit[s] and vegetables, nuts, natural vegetable oils, and whole grains†¦Ã¢â‚¬  (â€Å"sharecare†) An omnivorous diet is one which is based on the consumption of both animal products (red meat, poultry, fish, etc.) and plant foods. Due to the fact that plant based diets have changed and now incorporate varying levels of animal consumption there is a need to define the levels so that confusion can be avoided. The four categories of plant based diets are ovo-lacto vegetarianism, pescetarianism, lacto vegetarianism and total-vegetarianism. Ovo-lacto vegetarianism is when an individual consumes primarily plant based foods while still consuming eggs and dairy products. (Null 4) Pescetarianism is a diet which abstains from consuming land animals and birds while still consuming seafood as a support to a primarily plant based diet. (â€Å"Pescetarian Life†) Lacto vegetarianism is a diet which contains dairy products like an ovo-lacto diet except eggs are no longer consumed. A total vegetarianism diet is a one which consists of only plant foods and abstains from any animal product such as, â€Å"meat, poultry, fish, eggs, dairy products, and honey.† (Null 4)The research presented in this will focus on a total-vegetarian diet because it allows for the least variables and is the diet which most studies use because of the limited variables. Nutrients required by the human body which are viewed by many as scarce in a plant based diet The human body is a complex system which requires the support of nutrients which are provided by the food individual’s consume and then absorb into their bodies. In order to look at the ability of a plant based diet to support an 18-35 year old person’s nutritional needs we will first examine those most basic nutrients required by a human. This section of the paper will look at the following nutrients; carbohydrates, proteins, fats, fiber, calcium, and vitamin B12. Carbohydrates The term carbohydrate refers to the naturally occurring molecules which consist of carbon, hydrogen and oxygen. This molecule is used throughout the animal kingdom as the most abundant and â€Å"†¦least expensive source of energy.† (Guthrie 35) The idea of being an inexpensive source of energy refers to the fact that carbohydrates are easily broken down by the human digestive system which converts them into glucose. The belief that carbohydrates present the most abundant source of energy while still being nutritious can be misleading due to the two main types of carbohydrates, simple and complex. Simple carbohydrates are present in most diets in the form of fructose (sweet sugars), sucrose (table sugar), maltose and lactose. (Driskell 29) These simple carbohydrates are easily broken down, converted into glucose for the body and easily flow into the blood stream. The downside to this form of carbohydrates is that they are most common in the form of refined sugars or refine d flours which retain very few vitamins after being processed. (â€Å"HealthStyle Fitness†) As the body uses this form of glucose a cycle begins which involves fluctuations of high and low blood sugar. This cycle works when blood sugar rises after the consumption of simple carbs and then as the blood sugar begins to drop the body demands more simple carbs to bring blood sugar levels back to up. The cycle that is formed essentially keeps the body from burning body fat because there is a continuous demand and consumption of simple carbohydrates. The second form of carbohydrates is that of complex carbohydrates which consist of polysaccharides, three or more monosaccharides. These complex carbs are found in the form of starch, fiber and glycogen (animal starch). Those complex carbohydrates consumed in the form of starch are found in plant foods like corn, wheat, potatoes, cereals, pastas, and beans. When they are broken down these carbs allow for the slow production and release of glucose into the blood stream and allowing for a consistent blood sugar level. (Guthrie 27) Dietary fiber is another form of complex carbs which are present in plant foods because fiber is â€Å"†¦the structural framework of plants.† (Driskell 29) The presence of dietary fiber allows for the slow breakdown of starches because the human body lacks the enzyme necessary to break down most forms of fiber. (Driskell 29) The last form of complex carbohydrates is glycogen which is found in animal muscles and livers. Simply put, simple carbohydrates are easily broken down and absorbed by the human body but poses few vitamins while complex carbohydrates are broken down slowly by the human body allowing for stable blood sugar levels. Proteins Another macronutrient group is that of proteins or on a more basic level, amino acids. When people take in proteins they are in fact consuming strings of amino acids which are broken down and then put together in varying structures to be used to â€Å"†¦construct tissue proteins, hormones, enzymes and other substances crucial to our existence.† (Kimball 49) The human body has the ability to produce most of the amino acids required for existence while some amino acids, called essential amino acids, cannot be produced in the quantity required for life support. Proteins are commonly viewed as complete proteins which supply all amino acids required by the human body, both essential and nonessential amino acids. The most common source of complete proteins is animal foods because animal muscle already possesses all amino acids required for tissue growth. (Guthrie 85) This perception of requiring complete proteins in order to consume the required amount of proteins is not the on ly way of reaching this daily goal. Fat One nutrient which accounts for nearly 41% of the American diet today is fat in either its natural or its altered state. (Guthrie 45) Throughout human history having excess fat was seen as a sign of wealth and power because those who could afford to be fat were those people who did not have to work for a living. Over the years this has become a social factor because fat has the attribute of altering food’s flavor and in a sense addicting people to it’s’ taste. However fat has two main factors in the human body other than making foods palatable and those factors are as stored energy and supporting healthy cell structures. The interesting fact that is misconstrued is that the essential fatty acids are everywhere in the news are not the main contributor to these factors, instead, â€Å"Highly unsaturated fatty acids are even more physiologically active in the body than essential fatty acids and†¦are needed for the formation of healthy cell membranes.† (C arlson 31) One of the reasons why the human body requires fat for the formation of cell membranes is because as people move they need their cells to move with them. If people had rigid cell membranes like plants we wouldn’t be able to breath much less walk down the street. In addition to aiding in cell membranes composition, fat is also used as energy reserves within the human body so that when food consumption does not meet energy requirements then the body can burn fat as a source of energy. (Guthrie 56) The reason why fat is used as a reserve for energy is because when one gram of fat is burned for energy it creates 9 calories of energy as opposed to carbohydrates and proteins which produces 4 calories per gram. Overall fat is a required part of the human diet because of its use in cell productions as well as a source of energy reserves for everyday life. Fiber Fiber has recently hit the news as a required part of the human diet not because it was recently discovered but because people have been consuming far too little. Dietary fiber can be described as the, â€Å"†¦portion of consumed plant material that is resistant to degradation by the enzymes of the small intestine.† (Carlson 51) The reason why consuming enough fiber is important is because when people eat complex carbs they are taking in fiber which allows for a consistent blood sugar level. However as carbohydrates are refined they are stripped of not only their vitamin content but also of their fiber content. When fibers are striped from carbohydrates it makes intestinal passage time faster and those vitamins and macronutrients present do not have enough time to be absorbed into the body. Another reason why rigid fibers are required in the human diet is to keep the intestines clear. As humans consume non-fibrous material it tends to collect along the sides of the intestinal tract and leave layers of buildup similar to plaque in arteries. The reason why fiber is needed is to keep food from building up because the buildup can limit the ability of the intestines to absorb those nutrients which are consumed. (Calloway 145) Fiber is one of the requirements which many people do not think about because they cannot simply eat a handful of fiber, instead people must make sure to incorporate it in their diets. Calcium Most of the American culture is told to drink milk so that they can consume the amount of calcium required for strong bones and healthy living. This urge to consume calcium is spurred by the thought that in order to maintain healthy bone structure people must consume enormous amounts of calcium. This concept may be true in those people still growing during their early years and for people over the age of 50 whose bones begin to release more and more calcium, however most college students do not require excessive amounts of calcium. Once people are around 18-20 their bones either cease to grow or slow down to the point of millimeters and then calcium is used in blood plasma as a key ingredient for clotting as well as a required element for muscle contraction. (Calloway 149) Another misconception is that calcium is released directly into the blood stream for use after digestion when in fact calcium used in the blood is taken from our bones and ingested calcium merely replaces the lost calcium. Nutrients required by the human body which are viewed by many as scarce in a plant based diet and where they can found in plant based foods The most common misconception that people have about plant based diets is that they will not consume enough nutrients required for their overall health. This misconception is false in all fields except vitamin B12. A plant based diet provides the human body with enough carbohydrates, proteins, fats, calcium, and fiber for a more than healthy lifestyle. The following section will provide the sources of nutrients described above for persons who consume a plant based diet. Carbohydrate The most important source of energy in a plant based diet is that of carbohydrates because all plant based foods present carbohydrates. The important factor which most persons living on a plant based diet acknowledge is that complex carbohydrates are the basis of all meals because of the longevity of the calories consumed. Instead of eating all fruits, which are mostly simple carbohydrates, total vegetarians eat other plant foods. These foods, which consist of fiber, increases the time complex carbs remain in the intestinal track and increase the time required for digestion. An example is the consumption of serving of black berries compared to a serving of oatmeal. The black berries will break down quickly and cause the person’s blood sugar to spike. The oatmeal on the other hand will remain in the person’s stomach for a greater period of time and also stay in the intestines for longer allowing for the same amount of calories consumed as in the black berries to be relea sed into the blood stream slowly. Protein The next major requirement of a plant based diet is protein or more specifically amino acids. One of the major misconceptions in America is that proteins only exist in animal foods because protein is used to grow muscle so therefore eating muscle provides the ingredients to support muscle. This is interesting because the largest land animals in the world are those which consume only plants and they maintain the greatest muscle mass known to man. Amino acids are present in all plants, however, not all amino acids are present at the same time meaning that plants do not contain complete proteins. However, â€Å"†¦when grains and beans are consumed together, their amino acid profiles complement each other and produce a mix that is ‘complete’ and therefore a good match to the body’s needs.† (Norris 15) This means that while plant based foods do not contain complete proteins in themselves they do create complete proteins when consumed with additional plant based foods. This concept is supported by developing nations where diets consist primarily of plant foods and yet these people consume enough proteins. (Guthrie 82) Most sources agree that when the proper amount of calories are consumed for an individual the person in question is also taking in enough protein because of the combination of amino acids throughout the plant world. Fats Fats are the second most over consumed major nutrient after proteins because in an omnivorous diet fat is in all animal products. Most fat that is consumed directly from animal products are â€Å"†¦invisible fat, including that marbled throughout meat fibers, in finely divided form either emulsified in egg yolk or homogenized in whole milk, or found as a constituent of whole-grain cereals and nuts.† (Guthrie 45) In addition to these direct animal fats there has been an increase in the amount of fats consumed in the form of vegetable oils, which are becoming a staple in today’s society thanks to fast food chains. This last fact points out that reducing the amount of fat in one’s diet cannot be isolated to the reduction of animal foods but is instead connected to a healthy diet in general where oils are reduced so that they do not dominate one’s fat intake. In addition to the oil concept, society has suggested that consuming only essential fatty acids i s required while research has found little evidence proving health benefits substantial enough to eliminate additional fats from one’s diet. (Norris 52) Fiber Fiber is one nutrient which is overly simple to find in plant based foods because the majority of fibers out there today are plant based. When people eat enough complex carbohydrates they are also consuming their required amount of fiber, â€Å"the typical American omnivorous diet contains only about 10-20 grams of fiber daily†¦most vegans consume 25-50 grams per day.† (Carlson 52). The only factor which people should look at when preparing their plant based meals is to not cook their foods to long because fiber can be broken down when enough heat is present for a long enough period of time. Calcium and Vitamin B12 Calcium and Vitamin B12 are two nutrients which require people to pay attention to the foods that they eat in order to meet dietary requirements. Those people who live on a plant based diet should make sure to incorporate dark greens in their diet because these are the main source of calcium which they should be eating. In fact, â€Å"†¦kale, collards, broccoli, and turnip greens†¦Ã¢â‚¬  can provide as much as 50%of our daily calcium requirements. (Norris 43) This means that by eating one serving of these vegetables someone has the ability to meet their calcium requirements because, â€Å"†¦even omnivores get as much as 40 percent of their calcium from plant foods.† (Nollin 42) On the other hand, vitamin B12 is more difficult to get by eating plant foods because the bacteria which produce it are found in animals and their feces. Therefore most total vegetarians take a supplement to ensure they are getting enough B12 if they don’t already consume fortifi ed plant foods like fortified soy milk or fortified cereals. Conclusion A vegetarian lifestyle has the ability to supply all required components of a nutritious diet required by an 18-35 year old American. The section on carbohydrates highlights the importance of a diet composed of complex carbohydrates and few simple carbohydrates primarily because of the complex carbs retention of vitamins. After reading the sections on protein the reader can now see how a plant based diet provides just as much protein as an omnivorous diet because of the compounding amino acids present in plant foods. Plant based diets also meet fat needs because of the fat content in nuts and vegetable oils. Therefore living on a plant based diet allows for nutritional needs of human beings to be met without including the consumption of animal products.
