Affirmative Action Is A Moral And Just Purpose - 1279 Words

Affirmative Action was originally established by former President John F. Kennedy on March 6, 1961 in his executive order, which included a provision that mandated federally funded projects to take â€Å"affirmative action† to ensure that hiring and employment were free of racial bias (#4). Over the years, colleges and universities began to adopt similar policies in their admissions process (#2). The purpose of affirmative action is to provide an equal ground for women and people of color in the workforce and educational institutions (#4). There are many debates and myths about affirmative action, some of which will be unraveled later in this paper. This policy does not mean it benefits unqualified minorities, but rather highlights qualified and over-qualified minorities to be considered by otherwise predominantly white institutions (#4). Affirmative action is supposed to aid the nation in establishing equal opportunity for all. In my opinion, affirmative action has a moral an d just purpose and I will be using Martin Luther King Jr., Mill, and Foucault to support my argument. The battle for equality is an ongoing struggle for women and minorities all over the United States.

Sophocles Antigone By Sophocles - 964 Words

In â€Å"Antigone† by Sophocles, a famous ancient Greek tragedian, the main character, Antigone, demonstrates a prohibited action in a strict, male-dominated society. Greek civilization upheld strong values and rules that were designed to enforce orderly behavior among its people. There were state laws created by the King, Creon, and divine laws created by the Gods. Divine law was superior to the king laws, and if that rule was disrupted, eternal consequences could ruin an individual. In this society, men were mighty, powerful, and in control of the kingdom. Women were traditionally treated as an underclass with no voice or power. Women were restricted from performing any masculine jobs, holding high civilization positions, and disobeying men. Although Greek civilization had strict standards for women, Antigone challenges the law through her actions in order to satisfy the Gods because it is what she thought was the right decision. The way women were treated was nothing compared to how the men were treated. There was no equality in this male dominated society which made it difficult for women to play a key role. Women faced obstacles on a daily basis and commonly endured hardships because of their gender. Women were primarily responsible for domestic chores around the house and taking care of the children. The most valuable thing a woman could do was become pregnant with a child, however in Greek civilization having a boy was more favored.

Plagiarism A Pestilence in Education Essay - 1840 Words

Plagiarism: The Pestilence in Education When I think of plagiarism, I imagine a person literally stealing from another individual. The term plagiarism is derived from the Latin word plagi rius, which essentially represents the felony of kidnapping. An individual who kidnaps anothers work is a felon. Obviously, this form of larceny is not as immoral as the form for which one can be imprisoned; however, most educators and honest students view plagiarism in this manner. Within education I conceive that there are two kinds of plagiarism: copying a paper word-for-word and not providing the correct recognition to the original author when utilizing their composition. I believe that each situation of plagiarism should be considered serious†¦show more content†¦Of course, I did not have the right to explain, because I was deemed a cheater, one who could not be trusted, for the rest of the semester. In addition to being demoralized that day, my instructor continued to scrutinize my work and me very closely for the remainder of the term, and I felt humiliated from that day forward. Although I have since learned never to allow anyone to peruse anything that I have written, the failure to allow me to defend myself and give me the benefit of the doubt was cruel and unusual punishment given that this was my first offense, and might not even be deemed an offense if a poll had been taken. Whenever we had a test or quiz, the instructor requested that I sit in the front, near his desk. Projects and papers were also graded harshly. All of this happened because I was unfairly accused of assisting an act of plagiarism. Steiner 3 Another example of plagiarism occurred in my English class in high school. I was obligated to submit all computer-typed work to turn-it-in-dot-com. This concept of surrendering my hard work to a computer-generated website that scanned it for copied sentence structure and like-words was completely foreign to me.

Judge`s Wife By Allende Essays - Frankenstein, Victor Frankenstein

Judge`s Wife By Allende In "The Judge's Wife" the author, Isabel Allende, uses a variety of techniques to make full use of the limited space within her short story. By using strong imagery, providing a background, providing believable human actions, and examining justice, M. Allende creates a piece readers can understand to the point of empathy. Because her short story examines human behavior in respect to passions, justice, and emotion (love) in a plausible manner one can find close similarities between her work and that of Mary Shelly's Frankenstein. The author makes use of imagery to embellish not only upon her environment, but also her characters. M. Allende presents the ideas of corruption, innocence, and strictness simply through well-selected adjectives that lend eloquently to the descriptions of her characters. The strait laced judge being "...dressed formally in black ... and his boots always shone with bees wax " (Allende, 422). One can infer by details such as those that that particular individual appreciates formality, and considering his desert location, a strict adherence to it. The author also uses images of deformity demonstrate the corruption of her main character, Nicholas Vidal; by providing him with four (4) nipples and a scared face the reader can have a visual representation of the character's tragic formation. In much the same manner, one can see such development within Frankenstein's creation. The monster's grotesque outward appearance reflects his corrupted creation. Using such imagery the author allows the readers to form a solid conception of the plight of their characters. Mary Shelly uses lovely poetic imagery in much the same way to define, and give three-dimensional presence to her characters. Such use of imagery for the purpose of character definition can most clearly be seen in her description of her monster: "His limbs were in proportion, and I had selected his features as beautiful. Beautiful, Great GOD! His yellow skin scarcely covered the work of muscles and arteries beneath; his hair was of a lustrous black and flowering; his teeth pearly whiteness; but these luxuriances only formed a more horrid contrast with his watery eyes, that seemed almost of the same colour as the dunwhite sockets in which they were set, his shriveled complexion and strait black lips." (Shelly, 56) In viewing the above passage, much of the same type of character definition can be seen; very similar to the manner in which Allende casts her deformed mold of her creature, Nicholas. Beyond merely presenting imagery to enhance the characters, the Allende also supplies background information in order to enhance the readers understanding of how the main character arrived at his current state. The author focuses on the main character's fatherless and loveless conception in order to accentuate how his development occurred. In a similar fashion Allende's character Nicholas Vidal was conceived in a similar fashion as Frankenstein's monster. Both are created and ultimately rejected by their creators who attempt to destroy them. These horrid monsters are invariably unwanted by their creators, thus their creators go to great lengths to attempt to snuff out the lives of the creations in order that they not wreak havoc upon the world. Both authors using this particular method of rejection to temper the souls of their monsters to the hardness of iron (Allende, 423). In each case this extreme form of temperament creates an almost supernatural being, filled with great destructive forces. Further extending upon the parallel roles of Nicholas and the Monster, a clear outcasting from society also aids in their murderous temperament. Each character finds himself rejected by society. The monster, from Frankenstein, is rejected by the family he assists solely due to his grotesque appearance. In much the same way Nicholas is assumed early on in his life by "decent folk" to become a criminal due to the telling marks on his face. It may well be said that though the Judge, in his strait laced figure, may not have directly created Nicholas, yet in reality he probably did in deed, like the rest of society, stereotyped and eventually outcast Nicholas based solely upon the scars on his face. In each case the author makes use of societies tendency to categorize and reject an individual based solely on their exterior shells, rather than probing the unique individual. To solely focus upon the main character within this story would be folly when making a true comparison to Frankenstein. Indeed the role of the judge has many overlapping qualities with Victor Frankenstein. Each man peruses, as both texts put it, their own "creature", to the points of virtual insanity. In doing

angola crisis essays

angola crisis essays In past centuries, Angola was among the areas most-devastated by the slave trade. In recent decades, it has been afflicted with wars. However, in both eras, much of the violence was driven by powerful external forces. This is because Angola, with an abundance of oil and other resources, could develop into a very prosperous country if led and controlled by the right power. In 1975 Angola was released from colonialism by Portugal. This pivotal event in history sparked the beginning of a massive conflict between many of the key players in world power. These key players included the United States, Cuba, China, and the Soviet Union. After reading three separate accounts of the crisis in Angola (U.S. Senate hearings led by Secretary of State Henry Kissinger, a personal memoir by 1975 Assistant Secretary of State Nathaniel Davis, and a biography entitled In Search of Enemies: A CIA Story by John Stockwell), I have come to several conclusions. Although these three men all held important positions in the U.S. government, multiple contradictions exist in their chronologies of events. Of the discrepancies I found, all of them put Stockwell in opposition with Kissinger and Davis. I believe this is due to his position in the Central Intelligence Agency, where the greater availability of information was his advantage. Moreover, since all three accounts agree that the U.S. involvement was essentially a covert operation led by the CIA, I feel the account written by Stockwell was the most valid of the three. When looking at the differences in chronologies, it is necessary to start from the beginning of the conflict. The first difference I found dealt with CIA involvement in Angola. Stockwell, an experienced, senior CIA case officer (Stockwell, 31), marked early July 1974 as the start of CIA support. In July 1974 the CIA began funding Roberto without 40 committee approval, small amounts at first, but enough for ...

Are alternative energy sources the answer to ending human dependence Assignment

Are alternative energy sources the answer to ending human dependence on oil - Assignment Example There are numerous forms of energy such as geothermal, solar, fossil fuels, biomass, nuclear, and wind energy among others. Of all the forms of energy, human beings have tended to depend mostly on oil for their energy uses. Enerdata (2011) notes, oil is the most popular and dominant form of energy in recent times constituting over 60% when combined with coal. With the increasing energy consumption, dependency on oil increases. It is this increase that has raised concerns among environmental activists and other persons and institutions who are concerned with sustainable environment. Their concerns are informed by the fact that oil as a source of energy has limited capacity and cannot be relied upon to sustain the energy needs of the present and future generations. The other major concern is the fact that oil energy has adverse effects to the environment and has greatly contributed to the global warming phenomenon which is undermining the very existence of human life (Boyle, 2004). It is against this background that the need for alternative energy sources has heightened. Alternative energy sources are necessary in order to substitute oil energy as the major source of energy hence reducing dependency on it. Alternative energy sources will provide large amount of power which will be essential in meeting the energy needs of the world’s growing population. Alternative energy sources are the answer to ending human dependence on oil. Indeed, oil is the dominant energy source across the world presently. It is a non- renewable source of energy. It is a natural resource present in some parts of the world and has numerous applications. Despite having negative effects to the environment, oil is considered as one of the most efficient source of energy. However, due to immense consumption the resource is getting scarce. According to World Energy Outlook (2010), oil energy dominance as a source of energy cannot be disputed and has many uses in industries, automobiles, p lanes, and homes. Production of electricity in most instances relies on oil to run stream turbines. Cars, tractors, buses, and industrial machineries all depend on oil. Also, production of industrial products that are consumed by people is facilitated in great part by oil energy. In a nutshell, oil energy is intertwined to survival of the human race. However, this does not mean that oil energy has no substitutes (Tester et al, 2005). In order to understand oil energy and the importance of alternative to reduce dependency on it, it is important to understand the types of oil energy. They include; petrol, ethane, diesel, gasoline, liquefied petroleum gas, fuel oil, gasoline, kerosene, and fuel oil. Vital lubricants used in machineries and automobiles are also considered as oil products. All these types of oil and oil products play crucial role in making human life better and easier through increasing efficiency of machines and equipments. Despite the usefulness and many applications o f oil energy in the world, it is agreeable especially among ‘environmental conscious’ persons that oil energy have immense adverse effects to the environment and there is need to substitute it with alternative energy sources in order to reduce dependency on it. Turk and Bensel (2011) argue that oil energy is contributing to environmental degradation in numerous ways.

Effect of pH on Percent Oxygen Saturation of Haemaglobin

Effect of pH on Percent Oxygen Saturation of Haemaglobin Abstract The purpose of this lab was to determine the effect of changes in the pH and the partial pressure of oxygen on haemoglobin’s affinity for oxygen and percent oxygen saturation in the Bos taurus blood. At a lower pH (6.8) with a 21mmHg p50 value, it was found that the oxygen dissociation curve shifted to the right, which indicates that the Bohr Effect causes haemoglobin to lose its affinity for oxygen. This concludes that the increased carbon dioxide concentration forces haemoglobin to release its bound oxygen to the high metabolizing tissues (converting to deoxy-haemoglobin), but also forces the protein to bind more oxygen at the respiratory surfaces in order to transport enough oxygen to areas with a low oxygen partial pressure. At a higher pH (7.4), the oxygen dissociation curve shifted to the left with a 14mmHg p50 value since haemoglobin receives more oxygen, causing haemoglobin to have a higher affinity for oxygen and to remain as oxyhaemoglobin. Both sigmoid shaped curves contain a steep portion at 9.1mmHg and a plateau at 60mmHg. In conclusion, since the p50 value at pH 6.8 (21mmHg) is lower than the p50 value at pH 7.4 (14mmHg), this signifies that in an acidic environment, there is a higher partial pressure of oxygen in the environment as haemoglobin cannot bind the available oxygen as much due to its lowered affinity for oxygen. Introduction Haemoglobin is a specialized protein found inside the red blood cells of vertebrates that have developed organs for gaseous exchange as a substitute for simple diffusion. This respiratory pigment transports dissolved oxygen in the blood from the respiratory surface to the tissues through the circulatory system, and transports carbon dioxide back for excretion at the respiratory surface by exhalation. When one oxygen molecule binds to the iron containing heme group of the tetrameric-structured haemoglobin—which has four globulin subunits non-covalently linked to each other: two alpha- and two beta-polypeptide chains—its allosteric property increases its affinity for the addition of the next three successive oxygen molecules (Fenton et al., 2015). A total of four oxygen molecules can bind to this protein; however changes in the partial pressure of oxygen at the gas exchange site can affect haemoglobin’s percent oxygen saturation and changes in pH can alter haemoglo bin’s affinity for oxygen (also known as the Bohr Effect). The magnitude of the Bohr Effect in haemoglobin results from the breaking of the salt bridges between the histidine residues when the protein changes between its two structures at equilibrium: oxyhaemoglobin and deoxyhaemoglobin (Kilmartin, 1974; Zheng et al., 2013). During the structural shift, the histidine residues will react with the sulfhydryl group of the cysteine that is found in the deoxyhaemoglobin (Okonjo et al., 2014). Consequently, this change in the structural conformation of cysteine leads to a reduced Bohr Effect (Okonjo et al., 2014). Since deoxyhaemoglobin has been altered at a chemical level, it will experience a minimized Bohr Effect while its affinity for oxygen increases (Riggs, 1988). The Bohr Effect states that in a high pH alkaline environment, protons are released when oxygen is attached to haemoglobin; but are not released when in an acidic environment (Riggs, 1988). To what extent did the variations of PO2 and pH levels affect haemoglobin’s percent oxygen saturation in the Bos taurus blood was examined as the main purpose in this lab and is depicted by an oxygen dissociation curve. The resultant sigmoidal (S) shape relates the partial pressure of oxygen and haemoglobin’s percent oxygen saturation at different pH levels. Given that the manometer PO2 is held constant at the specific mmHg value, it is predicted that the oxygen dissociation curve will shift to the right at a pH of 6.8 (which is lower than the normal pH value of 7.4) as there is an increase in carbon dioxide concentration. This indicates that a pH drop will decrease the percent oxygen saturation of haemoglobin, and hence, its affinity for oxygen. Conversely, it is estimated that the curve will shift to the left at a pH of 7.4 as there are less carbon dioxide molecules in an alkaline environment. It is also predicted that at P50, there will be a difference in the percent oxygen saturation of haemoglobin at the different pH levels and that the two sigmoidal curves of the oxygen dissociation graph will eventually meet at equilibrium past P50 due to the Bohr Effect. In relation, Hill conducted his experiment with a similar procedure on human muscle and haemoglobin and concluded that at a higher pH level (muscle haemoglobin at pH 9.2 and blood haemoglobin at pH 9.2), the curve shifted to the left while at a lower pH level (muscle haemoglobin at pH 7.0 and blood haemoglobin at pH 7.0), the curve shifted to the right due to the Bohr Effect (Hill, 1936). Materials and Methods This experiment was conducted based on the BIO202 lab manual; however, the procedures performed for the Bos taurus at pH 7.4 under section 2 was deviated from the instructions provided. The maximum vacuum pressure was set at 750 mmHg instead of the listed value of 700mmHg since vacuum did not provide enough pressure at 700mmHg to deoxygenate the blood appropriately. My lab partners, Isabel, Zainab and Dianne, performed the experimental tests on Bos taurus buffered at pH 7.4. We collected the data conducted at pH 6.8 from our colleagues: Kashamala, Kiran, Jing, and Seevin. Results Figure 1 This oxygen dissociation curve graph depicts a logarithmic regression that relates the effect of the partial pressure of oxygen on haemoglobin’s percent oxygen saturation at both pH levels in Bos taurus. The manometer reading was converted to the partial pressure of oxygen with equation a listed in the appendix. In addition, the percentage transmittance value obtained from the spectrophotometer was converted to the percent oxygen saturation of haemoglobin using the equations of the two logarithmic regression curves. The P50 value at pH 6.8 is ~21mmHg and at pH 7.4 is ~14mmHg. This value reveals the change in the partial pressure of oxygen at the different pH levels due to the Bohr Effect when 50% of haemoglobin has been saturated. In Figure 1, the effect of the partial pressure of oxygen on the percent oxygen saturation of haemoglobin illustrates a sigmoidal shape as the main trend at the pH of 6.8 and 7.4. As PO2 increases, haemoglobin’s oxygen saturation also increases until a maximum amount of oxygen molecules have bound to this blood pigment. There are two patterns in this oxygen dissociation graph: (1) the steep (beginning at 9.1mmHg) and (2) the plateau (~60mmHg). The steep section begins when PO2 first rises from 9.1mmHg and the percent saturation increases drastically. At pH 6.8, the steepness levels off at point three where PO2 is 30.1mmHg and the percent saturation is at 84.0826%. At pH 7.4, the steepness levels off at point two where PO2 is 30.1mmHg and the saturation is at 83.6601%. When haemoglobin has reached its maximum oxygen capacity, the curve relating PO2 and haemoglobin saturation plateaus and become theoretical. During this period, haemoglobin maintains its maximum oxygen saturation at the maximum PO2. At pH 6.8, the maximum PO2 of 156.12mmHg occurs when the vacuum is not used (the pressure remains at 0mmHg), which gives haemoglobin a maximum theoretical oxygen saturation of 102.612%. At pH 7.4, the maximum PO2 of 156.12mmHg gives haemoglobin a maximum oxygen saturation of 97.7172%, which is slightly lower than the value at pH 6.8. In terms of pH change (the Bohr Effect), the curve of the lower pH shifts to the right while the curve of the higher pH shifts to the left. However, the starting point for both of the sigmoidal-shaped curves is at PO2 of 9.1mmHg, where 6.9259% saturation is for pH 6.8 and 8.3333% saturation is for pH 7.4. Discussion The results support the hypothesis that the oxygen dissociation curve will shift to the right at the pH value of 6.8, showing that haemoglobin’s (Hb’s) percent oxygen saturation decreases (due to a lower affinity for oxygen), whereas the graph will shift to the left at the pH value of 7.4, demonstrating that haemoglobin’s percent oxygen saturation increases (due to a higher affinity for oxygen). The p50 values from the graph indicates that in a basic environment, there is a lower partial pressure of oxygen in the environment (14mmHg) when compared to an acidic environment (21mmHg) because haemoglobin is able to bind to more of the available oxygen due to its increased affinity for oxygen whereas at pH 6.8, haemoglobin is unable to bind to as much oxygen due to its decreased affinity for oxygen. The reason behind this lowered oxygen affinity is due to the Bohr Effect and the high concentration of carbon dioxide present in the area. Moreover, the amount of carbon d ioxide concentration present changes the pH, which directly affects the ability of haemoglobin to bind to oxygen and readily dissociate oxygen. When there is a high partial pressure of oxygen in an area where haemoglobin is present, the tetrameric protein’s percentage saturation of oxygen increases as well because there are more available oxygen molecules to bind to. Due to the cluster of oxygen molecules around this blood pigment, haemoglobins affinity for oxygen becomes tremendously improved due to its allosteric property, where the next three successive oxygen molecules are more readily bound after the first one has been attached. From this, since haemoglobin is able to transport more oxygen molecules from the respiratory surface, a high concentration of oxygen is released into the blood plasma to be absorbed by the surrounding tissues. This is why in Figure 1, the graph—comparing the effect of the partial pressure of oxygen on haemoglobin saturation—has an incredibly steep curve at the beginning to indicate that haemoglobin is able to pick up a lot of oxygen molecules. From the graph, at pH 6.8, there is a high partial pressure of carbon dioxide where water reacts with carbon dioxide, generating H+ ions that produce an acidic environment with a low pH (Riggs, 1988). This reduces haemoglobin’s affinity for oxygen, where haemoglobin subsequently converts into deoxyhaemoglobin, which is its alternate structural form. In this acidic environment, the tissues are at a high metabolic rate and need more oxygen molecules. So, according to the Bohr Effect, haemoglobin will bind to more oxygen at the respiratory surface and release its oxygen content more readily at the tissues (where there is a lowered PO2) in order to raise the pH level back to normal. In essence, the body raises the partial pressure of oxygen to match that of carbon dioxide so that a dynamic equilibrium is created to raise blood pH back to normal levels and reduce the acidity – where the rate of perfusion and ventilation is equal to each other. In terms of the pH at 7.4, ther e is low carbon dioxide partial pressure where the environment is more alkaline. The Bohr Effect prevents the transport of oxygen to the deoxygenated area, so that the partial pressure of oxygen also decreases in respect to the partial pressure of carbon dioxide in an attempt to decrease the pH level. However, if haemoglobin attaches onto oxygen, protons are released, which equals out the increase in oxygen with an increase in carbon dioxide. Thus, the increase in H+ is directly proportional to the increase in CO2 (Riggs, 1988). The two curves eventually meet together at one point, indicating that Bos taurus is attempting to maintain pH equilibrium, where pH 6.8 attempts to raise Hb saturation for a more alkaline environment and pH 7.4 attempts to reduce Hb saturation for a more acidic environment. However, the Bohr Effect presents an advantage to the body when it is subjected to an oxygen deficient environment during exercise, where there is lactic acid buildup, a drop in blood pH, and an increase in carbon dioxide and hydrogen concentrations. The formation of carbonic acid and H+ ions from the reaction between water and carbon dioxide produces an acidic environment, lowering the pH levels (Riggs, 1988). In these regions, the production of carbon dioxide from muscle cells inhibits haemoglobin’s affinity for oxygen in the bloodstream by binding to haemoglobin itself, forming carbamino haemoglobin. Carbamino haemoglobin brings the H+ protons generated along with the carbon dioxide molecules to the lungs, where it is expelled through exhalation (Riggs, 1988). When this happens, there is not enough oxygen present at the tissues, so the Bohr Effect sends haemoglobin to the tissues, which readily releases its oxygen content into the tissues because it can no longer hold onto the molecule as it travels further into the bloodstream. Eventually, the Bohr Effect helps to raise blood pH back up to normal levels when enduring anaerobic respiration since haemoglobin is continually releasing its bound oxygen molecules as its affinity decreases to be the rising carbon dioxide levels. It is beneficial for haemoglobin to have a low affinity for oxygen near the tissues to increase oxygen uptake by the tissues, but to have a high affinity for oxygen at respiratory surfaces so haemoglobin can transport as much oxygen as possible, and as far into the body as possible. Thus, altering the oxygen affinity of haemoglobin is the bodys way of using the Bohr Effect to its advantage to solve the problem of lacking oxygen since more oxygen is released with an increase in carbon dioxide levels. One limitation of the experiment involved the absence of a spectrophotometer and the instrumental error of the vacuum. The vacuum failed to serve its purpose at the 700mmHg level, so it had to be increased to the 750mmHg level for the procedure done for pH 7.4, which results in an unfair comparison for the data done for pH 6.8. In conclusion, when pH is low, haemoglobin has less affinity for oxygen (lower saturation) whereas when pH is high, haemoglobin has more affinity for oxygen (higher saturation).

Appendix Figure A1 This standard curve graph depicts a linear regression that relates the effect of percent transmittance on the percent saturation of haemoglobin at both pH levels in Bos taurus. Oxygenated haemolysate was exposed to the vacuum at a maximum pressure of 700mmHg for 5 minutes to become entirely deoxygenated, which was added to the oxygenated haemolysate. Different amounts of 100% oxygenated and 100% deoxygenated haemoglobin were combined to give five various saturation percentages. A percent transmittance reading was taken for each of the saturation percentages, using a spectrophotometer. Oxygen Dissociation Curve (Sample Calculation #1) The manometer reading values are converted to the partial pressure of oxygen with the formula: (Equation a), where D is the barometric pressure (measured in mmHg), W is the water vapor pressure (measured in mmHg), and M is the manometer reading (measured in mmHg). The temperature was 22 ºC and the barometric pressure was 763mmHg for the lab room. Manometer reading at 300mmHg: Therefore, the partial pressure of oxygen at a manometer reading of 300mmHg is 93.1mmHg. Oxygen Dissociation Curve (Sample Calculation #2) The regression line equation is used to convert the percent transmittance to the percent oxygen saturation of haemoglobin. At the pH 6.8: The regression line equation is, where the variable y represents the percent transmittance value and the variable x represents the percent oxygen saturation of haemoglobin. Partial pressure of oxygen at 93.1mmHg: Therefore, the percent oxygen saturation of haemoglobin is 98.0559% at the pH 6.8. At the pH 7.4: The regression line equation is, where the variable y represents the percent transmittance value and the variable x represents the percent oxygen saturation of haemoglobin. Partial pressure of oxygen at 93.1mmHg: Therefore, the percent oxygen saturation of haemoglobin is 94.7712% at the pH 7.4.  Ã‚  

Racial and Multicultural Tolerance vs. Economic and Societal Benefits E

Racial and Multicultural Tolerance vs. Economic and Societal Benefits We exist in a society where intolerance for the racial and cultural differences of others is commonplace, and solidly rooted. Whether you live in the US, Middle East, Europe, or Asia, situations can be found where matters of money, domestic dispute, war, torture, and rape, have been incited or settled based on the ethnicity of parties involved (amnesty.org). Though it has for over a hundred years been the outspoken goal of certain societies to change this environment of unfairness, and in many cases injustice, – with the United States being the forerunner in this endeavor – the change, especially in the past several decades, can be considered modest at best (Lewis Mumford Report). For years we’ve listened to politicians support visionary ideas of bringing together people of varied ethnic backgrounds. â€Å"Until justice is blind to color,† stated Lyndon Johnson during his presidency, â€Å"until education is unaware of race, until opportunity is unconcerned with the color of men’s skin, emancipation will be a proclamation but not a fact.† Government programs like affirmative action were designed with the hope in mind of them being the keys to closing the gap between the economically and socially superior, and the historically underprivileged (Ravitch). Futurists and creative thinkers have come and gone preaching the idea, the dream, of a time when racial injustices would be a thing of the past, and yet it ironically seems we have a great distance to travel before this becomes reality. Perhaps it is not the assumed impossibility of closing this gap that keeps people from supporting these dreams.

Like water for Chocolate

These quotes show Tit's connection to food, which grow slowly in ever y chapter of the book. TIA prepares certain dishes for special occasions and at different times of the year and the food is connected to her emotions. First, the narrator begins by telling the reader that â€Å"The trouble with crying ova ere an onion is that once the chopping gets you started and the tears begin to well up, the next thing you know you just can't stop! † (3). The narrator is indirectly telling the reader that food is also like Faber 2 motions.As a matter of fact â€Å"TIA made her entrance into this world, preempt rely, right there on the kitchen table amid the smells of simmering noodle soup, thyme, bay leave s, and cilantro, steamed milk, garlic, and of course, onion. † (Quiver 56). This quote shows the at TIA is connected to food even before she can cook. The fact that Tit's onion induce d crying caused her to come to the world prematurely show us that in the novel tears are symbol of Tit's emotional connection, once again making food a really important role in the novel.Second, Food in Like Water for Chocolate doesn't only represent emotions it a I so represents tradition. â€Å"TIA gets her great cooking skills from Nacho, this is there e way of passing down the recipes from generation to generation. The recipes in Like Water for Chocolate are kept in the family. TIA then passes the recipes to Spenserian. Spenserian then passes them to her daughter who puts them in the book. The recipes that are passes down from generation to generation are also what tell us the story of TIA† (Tradition, Culture, Food in Lie eek Water for Chocolate 1).There was one day when Rosary did attempt to cook. When It TA tried nicely to give her some advice, Rosary became irritated and asked her to leave the kit chem.. The rice was obviously scorched, the meat dried out, the dessert burnt. But no one at the t able dared display the tiniest hint of displeasure, not after Mama Elena had pointedly remarked: â€Å"As for the first meal Rosary has cooked it isn't bad. Don't you agree, Pedro? † Of course, t hat afternoon the whole family felt sick to their stomachs† (50). The sickness that the family felt was that of the hate in she prepared the meal with.Third, Esquire' specifically tells the reader that the cook has the power to do stuff by saying â€Å"The kitchen becomes a veritable reservoir of creative and magical events, in which the cook who possesses this talent becomes artist, healer, and lover. Culinary activity I involves not just the Faber 3 combination of prescribed ingredients, but something personal and creative e matting from the cook, a magical quality which transforms the food and grants its powerful pro parties that go beyond physical satisfaction to provide spiritual nourishment as well† (60).The e use of Magical realism in this novel let's the reader understand more how in this novel the c ask possesses the talent to become an artist a healer or a lover. In conclusion, Food has a meaning of communication in this novel. F-DOD I s represented to show the emotions of TIA as well as the other characters. Food has a strong r ole in Like Water for Chocolate because food and it's tradition is what identifies the main char Cater, TIA . Through the novel we see that TIA was born in a Kitchen and lived cooking almost all h ere life.The title of he book is also symbolic because â€Å"the phrase like water for chocolate came f room Mexico.

The Prevalence Of Social Inequalities - 1960 Words

The article starts with the prevalence of social inequalities in the Indian society. It says that inequalities are distributed in the Indian society by the prevalent social structures which are based on caste, class and gender. So the people who get benefited from the development policy of the country are the ones who have mostly the high status and the fruits of policies that are formed reach to the higher sections of the society leaving behind the weaker sections of the society. The weaker sections of the society are those who have been marginalized for years. E.g.: Industrialization and privatization came in India saying that it will benefit the society as it will help to reduce unemployment by creating more jobs. Yes, there is no doubt, that it created N number of job opportunities. But for whom? It created job opportunities for them who were well educated and competent. It did not created jobs for the people who are marginalized or those whose lands were acquired in the process of setting up industries. They are still struggling.
