World Literature Essay Example
World Literature Essay Many obvious connections exist between the objectification of women in Sir Thomas Malorys Le Morte Darthur and the deepening importance of Christian, as opposed to pagan, mythologies on the cultural and social mores of Europe in the Middle Ages.à Among these obvious connections is the equation of femininity and more specifically feminine sexuality with a corruptive sense of worldliness, which can be understood to represent the connection in Christian consciousness between the earth and the Christian concept of sin.à In pre-Christian traditions, nature was associated with sacred space: If there was an Indo-European homeland, there were no temples there, only landscape. Sacral area must therefore in origin be identified by geography, not buildings[] natureââ¬â¢ inevitably underlies the choice of place in which to perform ritual (Dowden 27).à By contrast,à in the Christian world-view, sacredness was grounded in objects and in persons, rather than in the elemental forces o f nature.While it may be obvious to even the casual reader of Malory that Christian mythologyà plays a central role in his articulation of the myth of Arthur and the knights of the Round Table, what may be less obvious is the complete manner in which Christian ideals and images are intended to replace older, pre-Christian mythologies and ideas which were rooted in a feminine sense of nature and in the ancient Goddess religions.à In fact, it is not at all too strenuous an assertion to suggest that Le Morte Darthur represents, in its entirety, an attempt by Malory toà erect a throughly Christian facade on the scaffolding of ancient pagan myths.à One of the most important aspects of this facade is the way in which feminity and feminine sexuality are used as a bridge by which ancient suppositions of myth and nature are made into modern Christian myths which reflect a patriarchal rather than matriarchal vision of both nature and human society.Book thirteen of Le Morte Darthur , which covers the quest for the Holy Grail, comprises a microcosm of Malorysà blending of Christian and pagan mythologies.à Within the context ofà the work as aà whole, perhaps no individual book within the famous Winchester manuscript demonstrates more clearly Malorys intention, whether conscious or not, to usurp pre-Christian mythologies with Christian myth.à Not only does this chapter provide a clear case of pagan mythologies: those associated with the Fisher King myth, being subsumed by a distinctly Christian myth: that of the Holy Grail, but the figure of Galahad functions with the same transformative power, replacing ultimately all perceived feminine virtues once associated with pagan myth with the masculine-centered qualities of chivalric knighthood.à As the sole perfect representative of the Christian knight, Galahad is an extremely importantà facet of Malorys overall transformation of associated myth into a coherently Christian vision.Such an intenti on may or may not have been a conscious idea on Malorys behalf but rather, emerged as an instinctual outgrowth of the combining of mythological material with Christian sensibilities. Another example of this potentially unconscious tendency emerges, clearly, in the introductory verses of Chretiens Lancelot, which invokes feminine imagery as its source of moral inspiration, under the guise of a devotion to royalty:Since my lady of Champagne wishes me to undertake to write a romance, I shall very à à à gladly do so, being so devoted to her service as to do anything in the world for her, à à à à à without any intention of flattery.(Chretien 1-30)Similarly, when Book thirteen of Le Morte Darthur opens, it is clear that Malory intends the following tale to demonstrate not only aspects of adventure but aspects of morality, as well.à The opening scene of the book describes the arrival of a ful fayre gentylwoman (Malory, 612)à who gallops into Camelot, rising so fast that her hors was al besuetteà (Malory, 612).à Here there can be no doubt that the image of a fair woman of gentle breeding astride a hot, excited horse is meant to convey anything other than sexual energy. In point of fact, the ladys errand is one of a summoning which is connection to an earlier erotic interlude wherein Lancelot was hoodwinked into sleeping withà Elaine, King Pelles daughter.à Underlying this past-incident is an extremelyà important detail: that Lancelot had believed Elaine to be Guinevere.This is an important fact because it reveals that Lancelot, unwilling to commit the common sin of fornication with Elaine, maintains his knightly virtue.à However, Lancelot is fully willing to commit adultery with his Queen, despite the fact that this adulterous behavior will destroy his knightly virtues and, in fact, endanger Camelot itself.à This reveals that Lancelot is essentially a pagan at heart, unwilling to accept the Christian morals of temperance an d allegiance to a King, and not a Queen. Lancelot is a goddess worshiper and this single fault in his otherwise virtuous character, brings about the downfall of Camelot which, ironically, is only reversed by Lancelots bastard son with Elaine, Galahad.à What is notable about the rather intricate relationships between the characters of Arthurs court and those who associate with it is that relationships are immediately brought into a singular and ever-present contrast: the contrast between masculine virtue and feminine virtue. This contrast is very often expressed as outright conflict and in every case where there is a conflict between two characters, that conflict can be understood as a function of the gender-based division of virtues which is the underlying theme of not only Book thirteen, but of Le Morte Darthur as a whole.Again, this predilection toward the convergence of matriarchal imagery with directly Christian myth is conveyed directly through the relationships between the characters inà Le Morte Darthur.à For example, the character of Lancelot as envisioned by Malory, departs from Chretiens earlier envisioning, specifically in regard to the sexual relationship between Lancelot and Guinevere. à For Chretien, the focus of the relationship is on Lancelot as an object of the Queens desire.à This desire, masked as it must be, plays a key role in Lancelots climactic fight against Meleagant which is foreshadowed inà Chretiens Lancelot by Guineveres internal monologue.à As the Queen assesses Lancelot as the most desirable of knights, so, too, the reader of Chretiens Lancelot will see him as flawless. Along with the Queen, the reader will feel never so glad in her life as she was for his return (Chretien, 6730) and Lancelot will appear to be the completion of joy.à In Queen Guineveres fascinating inner-monologue, Chretien paints a portrait of Lancelot as the most sublime of figures:Why is not her joy complete? Is it mingled with anger or hate? No, certainly, not at all; but it may be that the King or some of the others who are there, and who are watchingà à à à à à à à à à à what takes place, would have taken the whole situation in, if, while all were looking on, she had followed the dictates of her heart.(Chretien 6729-7004)Chretien goes so far as to suggest that the Queen desires infidelity with Lancelot, postponing the greeting until it shall see and espy a suitable and more private place where they would fare better than here and now (Chretien, 7004), but he refrains from injecting reciprocaldesire in Lancelots character outside of that which manifests as knightly deeds in the Queens honor. The division of virtues has signaled a moral lapse on the part of the Queen in Chretiens story; Malory, however, pushes the relationship a step further in implicating Lancelot directly in the erotic sin of adultery.à Of note is the historical fact that when Malory wrote about Lancelot and Guinevere, he did not use Chretien as his source (Goodrich, 62)à and this fact is evident in the portrayal of theà couple in Le Morte Darthur.Although Malory regards the focal point of the breakdown of virtue on the patriarchal side of the equation, that is, on Lancelots, rather than Guineveres desire, his impulse to do so is based on the fundamental Christian understanding that the seductive power of feminine sexuality is corruptive to even the most noble of knights.à In other words, it was natural in the Christian philosophy of the Middle Ages to equate sin with sexuality and women, as agents of sexuality, are then posited as agents of temptation and sin.à Similarly, because women are viewed as being closer to nature and closer to natures corrupting forces, the Christian dogmas which reject the earthly world in favor of the neo-Platonic conception of heaven are the same impulses which, in the Middle Ages, contributed to the view that womens sexuality, even a Queens, was naturall y corruptive. However, such a transition from myths which originally exalted nature and feminine energy to myth whichà essentially inverted these ideas was neither directly accomplished by medieval writers, nor fully expressed as such by them.Instead, strange combinations of nature-imagery and Christian imagery collide in the Arthurian romances of Malory and Chretien and these strange collisions produce unique and beautiful images which reflect, not a total conversion from animism to Christianity or from femininity to masculinity in spiritual myth, but the intention to accomplish such a total transformation. A great example of this collision of myths can be found in Chretiens description of the Kings sycamore field: In the field there stood a sycamore as fair as any tree could be; it was wide-spread and covered a large area, and around it grew a fine border of thick fresh grass which was green at all seasons of the year (Chretien Vv. 7005-7008).à Obviously, this description is animistic, and deeply rooted in nature and one might convincingly take it as an expression of animistic (or pagan) spirituality.à The image recalls the pre-Christian idea of sacred spaces in nature which emphasizes natural objects rather than created temples: the sacrality of a grove may rest in the identifiable wood or forest, rather than on the altar placed, doubtless conveniently, within it (Dowden 26).The next passage, directly following, reveals the simultaneous impulse toward Christianity: Under this fair and stately sycamore, which was planted back in Abels time, there rises a clear spring of water which flows away hurriedly (Chretien Vv. 7008-7009).à Note that nature has been anchored in a patriarchal energy, Abels energy, in this passage, which concludes There it pleases the King to take his seat where nothing unpleasant is in sight (Chretien Vv. 7119.).à The passages reveal a dual impulse: one toward nature and one toward Christian morality which is an important duality and in fact a possible duality only to a mind which projects a state of sin onto both femininity and the natural world.If one understands the division of virtues based on genderà to indicate merely the admittedly idealized social mores associated by Mallory with a mythical, European past, then necessarily, the urgency of the protection of virtues along gender lines as it is expressed throughoutà Le Morte Darthur becomes dogmatic, and almost absurdly so.à However, if the schism of virtues based on gender is viewed as indicative of a more fundamental, in fact religious function of myth, then the objectification of women as expressedà in Le Morte Darthur stands for something much more than a set of social mores. à The objectification of women inà Le Morte Darthur is, in fact, the main way in which Mallory is able to subvert matriarchal myths to patriarchal myths; pagan myths to Christian myths. Nowhere is this intention (or unconscious subversion) more obvio us than in Malorys characterization of Galahad.à In addition to being the off-spring of Lancelots sinful tryst with Elaine (whom he mistook for Guinevere),à Galahad marks theà pivotal transition point in Book thirteen of Le Morte Darthur simply byà appearing.à The appearance of Galahad implies two profoundly important things: first, that sin has consequence no matter how seemingly unintentional and secondly, that goodness (or redemption) can be born from sin, which is a specifically Christian idea, reflected most obviously by the crucifixion of Christ itself.The idea of redemption through Christ is Malorys thematic target in Book thirteen of Le Morte Darthur.à However, because the animistic myths and pagan legends that infused his work ran contrary to this impulse, due to the Christian positing of nature as being both feminine and intrinsically sinful, Malory had recourse to devise some symbol which would essentially unite the pagan myth of the Fisher King with t he Christian myth of redemption. This symbol, obviously, is the Holy Grail, but the Holy Grail is defined, in Le Morte Darthur not so much by any intrinsic capacities or powers which are overtly attributed to it; rather its qualities are defined by those who seek it: primarily Arthur and Galahad.à à The grail essentially stands for all of the aggregate qualities which reside in the hypothetical knight (or King) who receives the grail, qualities which, in turn, are embodied by the seekers.à This means, to understand what the grail represents in Malory, it is foremost necessary to understand the character of Galahad, who, alone, eventually succeeds in finding the Holy Grail.Galahad is introduced to the reader as having come from femininity and from nature.à Lancelot discovers him living amid nuns in a beautiful woodland and the nuns regard Galahad as the essence of purity: Sire sayd they alle we brynge yow here thys child / the whiche we haue nourisshed / and we praye yow t o make hym a knyght / for of a more worthyer mans hande may he not receyue the ordre of knyghthode (Malory, 613)à Galahads connection with the Holy Grail is thereby foreshadowed andà explained.à He will emerge as the truest of knights because he is the purest.à When Lancelot regards young Galahad, he views him as semely and demure as a douue / with alle maner of good fetures / that he wende of his age neuer to haue sene soo fayre a man of forme (Malory, 613) and this implies that Lancelot instinctively knows his son is a more complete knight than he is himself.The key to understanding that both Galahad and the grail represent the redemptive power of Christ is to remember that Galahad was born from feminine trickery and was raised in the sinful influence of wild nature, among women, separated from his knightly father due to his fathers carnal sin.à Therefore Galahad is, himself, born of sin and as Guinevere notes that, he resembled moche vnto sire Launcelot I may wel s uppose said the quene / that syr Launcelot begatte hym on kynge Pelles doughter / by the whiche he was made to lye by / by enchauntement (Malory, 617).à She remembers that Galahad no matter what his virtues seem to be, was born of feminine enchantment and she is able to use this mindfulness to deceive herself into believing that Lancelot, despite his sin, remains noble and virtuous.The complete transformation of the cyclical re-birthing qualities which are inherent to nature and which had been a previous part of the feminine-centered pagan religions which were based in an animistic appraisal of nature, is accomplished by Malory merely by the inclusion of the character of Galahad himself: sir Galahad is a mayd and synned neuer (Malory, 641). à By describing Galahad as a maid and yet not intending to diminish his stature, Malory is conferring upon Galahad the virtuousness and spiritual exaltation which had been previously bestowed upon femininity in the pagan and animistic religi ons which preceded Christianity.à The basic thrust of the sobriquet is to suggest that Galahad is chaste.à This is the reason that the word maid deserves special consideration.By contrast, Sir Gawaine, who also seeks the Holy Grail, like Lancelot, has experienced an immersion into feminine trickery disavowed him of this same capacity: to unite the virtues of feminity with the virtues of masculinity and in doing so become Christ-like.à Instead, he is told that he, Gawaine, has failed a crucial test: Soo thow syr launcelot whan the hooly Grayle was broughte afore the / he fonde in the noo fruyte / nor good thoughte nor good wille and defowled with lechery (Malory, 641).à Therefore Galahads status as a maid surely refers most significantly to his chastity and his ability to resist the decadent charms of feminine sexuality.While Malorys objectification of feminity may be too subtle for the modern reader to fully comprehend, this same impulse is given excellent expression by director John Boorman in his film Excalibur, which expresses the same fusion of feminine/pagan and masculine/Christian motifs in its portrayal of the quest for the Holy Grail.However, the movie distorts Malorys original conception of the grail quest by substituting the character of Percival for that of Galahad.à This substitution is also resonant with the work of Richard Wager who, in 1882, created an opera called Parsifal which was, itself, inspired byà the enormous popularity of Parzival (Goodrich, 77) a poem written by Wolfram Van Escenbach between about 1200 and 1210à (Goodrich, 77).à This poem reveals a similar transformation pagan-to-Christian ideals and images, indicating the heros are those who fight on behalf of the Christian church: See how Christian men baptized to Rome wend their pilgrim way, So there was the heathen custom. At Bagdad was their papal right, And the Baruch as seemed his office purged their sins with his word ofà might. (Wolfram, 206-209).à Both Van Escenbachs and Boormans depiction of Parsifal is meant to evoke, like Malorys Galahad, a character whichà is equal to the Holy Grail itself and which defines the Holy Grail.The transformation fromà Galahad to Percival in the movie Excalibur is backed up by the use of a Wagnerian score. This let-motif helps the viewer to understand that Parsifal is a character who embodies spiritual qualities, rather than merely those qualities which are commonly associated with knighthood.à In Excalibur, the Wagnerian score signals the Death of the Gods because it signals the death of paganism and the birth of Christianity.à With this transformation comes the transformation of femininity and the disempowerment of women.à Women become aspects of the pre-Christian world, the world before redemption which is vividly described in the draft-script for the movie Excalibur, during a scene in which Percival approaches Morganas tree of death: Dangling from the branches of a dead t ree are a dozen dead knights of the Round Table, crows pecking at the rotting flesh in the chinks of armor. Perceval rides up, cries out in horror, and spurs his horse away (Excalibur).à This is the land when Morgana rules, this is the same feminine power of destruction that gave birth to Mordred through trickery.à This is the inverse power of the Holy Grail; rather than masculine redemption in Christ, wanton destruction, thirst for power and revenge, and dangerous feminine sexuality have overtaken the world.à It is a world of disorder and implies by negative what the world would look like under the rule of a feminine power.Just as Morgana pledges herself to this world of disorder and revenge when she tricks Arthur: The moon flows in my blood to meet your seed. And already I bear him who will be King (Excalibur) she subverts nature, commits incest in order to further her desire for power and revenge.à Excalibur portrays the threatening aspect of femininity just as it is portrayed by Malory as being 1) rooted in nature and 2) rooted in sexuality.à Of course, the two ideas may be considered united in the sense that it is ultimately feminine reproductive power which stands as the central focus of both male and female virtue in regard to Malorys idealized vision of the chivalric code. Purity is equated with redemption, but it is not the purity or redemption of birth into the natural world, but the purity and redemption of the rebirth of the individual in Christ which is true purity.à As such, the Christian concept of universal sin supplants the pre-Christian ideal of nature and birth as sacred processes adn replaces these ideas with the concepts of sin and redemption.à Because one is born sinful, birth is, itself, an evil.à Birth being deeply associated with women and with feminine reproductive sexuality is also evil.à Percival, being born out of sinful lust, must be redeemed through Christ.à The let-motif of Wagners Death of the Gods insists that where the pagan gods vanish, a new God arises, and this musical cue, in Excalibur, centers the viewers attention on the redemptive aspects of the Holy Grail.As the draft-script of the movie indicates, the music is intended to function as the voice of the Holy Grail: Enchanting music from unseen singers grows and weaves. Perceval looks back to see the drawbridge slowly closing, trapping him inside (Excalibur).à This voice ultimately transforms into human words and a riddle is posed What is the secret of the chalice? Who does it serve? (Excalibur).à This riddle is the crux of Malorys transformative mythology, as represented by Boorman.à Obviously, in iconography of pagan or per-Christian mythology, the answer to the riddle would be the Queen or the the Goddess as Lancelot or even Gawaine might have answered.Instead, because the story of the grail marks an attempt at aà complete transformation of pre-Christian nature-myths to Christian symbology, the correct a nswer to the riddle is the ultimate disempowerment of femininity, because the correct answer for Malory and Boorman is that the Grail represents Arthur who is the King and who is now with the land.à When Percival answers: You and the land are one. Drink from the chalice. You will be reborn and the land with you (Excalibur) this answer transforms the land to rebirth.à the profound overthrow of pagan ideas is nearly complete: where once the earth was a place of sin and dangerous feminine sexuality, the land is now reborn in Arthur, in Christ, through the Grail which redeems the world. Where once nature stood for sacredness and holiness, now an artifact: the Grail and a man: Arthur stand as sacred entities.à Percivals final answer to the Grail is to divulge the secret that the Grail is, itself, a man: You are my lord and King. You are Arthur (Excalibur). That redemption in Christ is the sole way in which one may attain a state of purity and innocence is a distinctly Christian idea.à The use of pre-Christian myths and imagery, largely drawn from nature, by Malory in Book thirteen of Le Morte Darthur serves the dual function of supplanting pagan ideals with Christian ideals and providing a deep, mythological basis for his modern legend of the Knights of the Round Table.

The belief that Odysseus was already dead has given these suitors the courage to slaughter his livestock, camp at his home, bother his wife at every opportunity, and drink his wine.à It was Athena herself who first suggested that Telemachus visit King Menelaus and Nestor who were with his father during the Trojan War.

(Oedipus the King 648). These were uttered by Oedipus the King when he had blinded himself for the realization and shame of having killed his father and married his mother.à At that point, his mother and wife, Queen Jocasta had already committed suicide.à Oedipus was at that juncture between lamentation and meeting his replacement as the ruler of Thebes, Creon. Specifically, Oedipus was not only bemoaning his fate but was blaming the person whom he thought was responsible for saving his life while still as an infant. An oracle had warned his parents, King Laius and Queen Jocasta about the deed or misdeeds the child would do when he grow up.à It was then both decided to have him killed.à Fortunately or unfortunately, the murder did not happen.à It was to this savior of his infanthood that Oedipus was reserving his strongest curse.à He was blaming the person instead of à himself for contributing to the fulfillment of the oracle.à He said that it was not kindness to save him then considering the situation he has found himself into in his mature years.à Oedipus lamentations, together with the chorus of this play by Sophocles, were a condemnation of his fate.à Oedipus had gorged his eyes out for so that he could not see himself as the embodiment of shame.à What is being emphasized through the excerpt is the paradox of h aving an opportunity or chance to alter oneââ¬â¢s fate or oneââ¬â¢s helplessness in the face of destiny. The savior of Oedipus in his infancy could have terminated his life and in the process spare him from the fulfillment of a certain prediction.à Still the pain and suffering that Oedipus voluntarily undergoes indicated a sense of blame on his part and not purely on destiny. 3. à The captain of evil discovered himself In a handgrip harder than anything He had ever encountered in any man On the face of the earth. Every bone in his body Quailed and recoiled, but he could not escape (Beowulf 1195). This quotation described that portion of the Beowulf Epic where Grendel had grasped the arm of the supposedly sleeping Beowulf and realized that he had meet somebody who was more than a match for him. Grendel was the dreaded monster which had laid waste the Kingdom of Hrothgar.à Beowulf was the kinsman of Hygelac, ruler of the Geats who had offered his services to King Hrothgar to get rid of Grendel.à The struggle between the hero and the monster was so intense that the writer commented that it was surprising that Heorot, the great hall, was not greatly damaged. Beowulf is described as having the strength of thirty men.à No wonder that Grendel feared so much the outcome that he wrestled himself free from Beowulf although at the expense of wrenching his arm from its socket.à Beowulf then declared that the arm served as hall decoration. This part of the epic is a reversal of fortune for Hrothgar and his people.à Although Grendelââ¬â¢s mother exacts some revenge later on, this was the first time that somebody had withstood against the onslaught of the local monster.à It also described for the first time Beowulf in action and which reinforced the truthfulness of his previous narrations about other great deeds in the past. 4. à He ruled it well For fifty winters, grew old and wise As warden of the land Until one began To dominate the dark, a dragon on the prowl From the steep vaults of a stone-roofed barrow Where he guarded a hoard; there was a hidden passage, Unknown to men, but someone managed To enter by it and interfere With the heathen trove (Beowulf 1227). This is a reference to Beowulf as he reigned for fifty years as king in after the death of Hrothgarââ¬â¢s son.à That reign was noted for the peace when from out of the blue a mighty dragon laid havoc in the countryside.à The dragon has for its residence the neighboring mountains where it keeps its hoard of gold.à Unfortunately, a fugitive slave was able to steal some of the treasure the dragon was hoarding.à This put the dragon on the path of revenge which ultimately resulted to a showdown between itself and an aging Beowulf.à Beowulf with the help of a kinsman was able to kill the dragon but was also mortally wounded. The excerpt is a development after a fifty-year hiatus of serenity in the life of Beowulf.à It was the start of another dangerous quest which ultimately cost our hero his life. 5. à ââ¬Å"Roland, Companion, sound your Oliphant now, Charles will hear it, marching through those passes. I promise you, the Franks will come at once (Song of Roland 1276).â⬠The quote is uttered by Oliver, Rolandââ¬â¢s best friend, as the Saracen ambush party of a hundred thousand men was approaching them. Roland and a small party were appointed by Charlemagne to serve as his rear guard while the main army with the emperor proceeded towards France.à Charlemagneââ¬â¢s group was only twenty-miles away from Rolandââ¬â¢s.à The treachery of Ganelon, Rolandââ¬â¢s stepfather, has put Roland and his men in grave danger.à The passes of Roncevaux were the ambush point.à Seeing the approach of the great host, Oliver asked Roland to blow his famous horn Oliphant so that Charlemagne could aid them.à Roland refused; he believed that they could still best the Moors approaching them. He also added that the used of the great horn is something that should not be lightly taken.à A great battle ensued with Roland and his men vastly outnumbered.à During a respite in the battle, Roland blew Oliphant to summon Charlemagne.à It was too late; reinforcements did not arrive until everyone of the rear guard were already dead, including Roland.à Oliverââ¬â¢s appeal to Roland to ask for aid was a crucial point of the epic.à This was the point where the hero had to choose between an opportunity to prove or distinguish him until death or seek help and live to old age. Roland chose glory and death and rewarded himself with immortality. 6. à Nevertheless, the experience of our times shows that the princes who have done great things are the ones who have taken little account of their promises and who have known how to addle the brains of men with craft (The Prince 1955-à à 1956). This is considered by most to be the most offensive among many advices preached by Machiavelli.à This is what befits the adjective, ââ¬Å"Machiavellianâ⬠.à The author preceded this statement with sentence that commends rulers who keep faith through integrity and not through any sly or cunning. Yet he added in the cited selection that the great rulers seldom keep their promises and are adept in the art of deception.à Machiavelli is describing a ruler who is not restrained by conscience but would rather use his baser nature in the interest of achieving his goal.à The end justifies the means would have been addendum to this.à à He buttressed this statement with by relating about how Achilles and the other notables of old availed of the half-man and half-beast Chiron as their tutor.à The quotation is very important since it basically sums up the gist of what Machiavelli is preaching. 7. à An oath will bind Lanval and the king will put the matter in our hands. If he can provide proof and his beloved comes forward, and if what he said to incur the displeasure of the queen is true, then he will be pardoned, since he did not say it to spite her. And if he cannot furnish proof, then we must inform him that he will lose the service of the king and that the king must banish him (Lanval 1322). The person speaking is the Count of Cornwall regarding the case put forth by King Arthur against one of his loyal knights, Lanval.à Lanval was guilty of spurning the advances of Queen Guinevere and of uttering some words to the effect that he loved somebody whose servants were fairer than the queen. To avenge the insult to her person of which she was to be blamed-never mind that Lanval had broken some of the unspoken demands of the code of chivalry-she twisted some facts and made it appear that she was insulted without cause by Lanval. This angered the King so much that he himself brought the charges against Lanval.à The barons, who constituted the court, could easily come with a verdict of guilty.à The only way for Lanval to escape punishment was as the Count of Cornwall suggested provides proof of the truthfulness of his claim about his Belovedââ¬â¢s servants as fairer than the queen.à Lanval is at a predicament since his ladylove has not appeared before him for a lo ng time after that tiff with the queen.à The statement of the Count of Cornwall is relevant since it summarizes what happened and what is about to happen. It sets the story for a resolution which could go either good or bad for Lanval. 8.à After that, then, I kept approaching one person after another. I realized, with distress and à à à à à à alarm, that I was arousing hostility. Nevertheless, I thought I must attach the greatest importance to what pertained to the god. So, in seeking what the oracle meant, I had to go to all those with any reputation for knowledge (Apology of Socrates 762). This is Socrates explaining how he was trying to disprove or understand the oracle that he was the wisest man ever.à As he related to the Athenians, this came about when Chaerephon, a friend of his, approach the god of Delphi with the query if there ever was a wiser man than Socrates. The response was none.à Socrates explained that he approached persons of intellectual refute and talk to them and gauge the knowledge they were supposed to be good at.à Although he believed that a god could not lie, he wanted to find out if this was a mistake and was looking for somebody to bring back to Delphi and present as evidence to the contrary of what he has been described. He discovered that these persons were wise by reputation and not by actual reality.à He related that he finds himself wiser because of the premise that he does not know anything at all but is in the process of knowing while the person or persons he compare himself with are not really that wise as touted by themselv es and others.à We must remember that while Plato had Socrates explaining in Apology, a sentence against him has already been passed for supposedly corrupting the youth.à Apology clarifies this misconception and articulated his philosophy that a life that is always inquiring and trying to discover what is good is the best kind of life. 9.à à All things, says Plato, are produced by nature, by fortune, or by art; the greatest and mostà à à à beautiful by one or the other of the first two, the least and most imperfectly to the last (Essays, Montaigne 2193). This is one of the Essays of Montaigne entitled, ââ¬Å"Cannibalsâ⬠which reiterated Plato about the standards of beauty and goodness in things as they came into being either by nature, fortune, or art.à Montaigne agreed with the emphasis that the thing produced by nature is the greatest and most beautiful.à Montaigne was referring to the non-western worlds that have been described by his contemporaries in unpleasant terms.à This is perhaps done out of spite or fear that such a better world exists.à Montaigne is criticizing the tendency of the west to mislabel or misjudge a particular nation or country that has not belong or undergone western civilization. 10. à There is a play to-night before the King, One scene of it comes near the circumstance which I have told thee of my fatherââ¬â¢s death. I prithee, when thou seest that act afoot, even with the very comment of thy soul. Observe my uncle. If his occulted guilt do not itself unkennel in one speech, It is a damned ghost that we have seen, And my imaginations are as foul As Vulcanââ¬â¢s smithy. Give him heedful note, For I mine eyes will rivet to his face, and after we will both our judgments join In censure of his seeming. (Hamlet 2453) Hamlet is telling Horatio, his friend, that he has set up a play before the usurper king and his queen which would relate about the death of the former king. King Claudius has replaced Hamletââ¬â¢s father and is suspected of having murdered him.à Subsequently, he married Queen Gertrude, Hamletââ¬â¢s mother. Hamlet related to Horatio that he will be observing the king and looking for reactions when that particular scene is played out.à Until this point, Hamlet still needed to be convinced that the suspicion has basis.à This part of the play or what is quoted from Hamlet, prepares the audience for that point where guilt or innocence would be established as predicted by Hamlet.à This juncture will determine what Hamlet would project and what plans would he have if the guilt or innocence is determined. This holds the entire structure together where the days of brooding could be replaced by anger, disappointment, and plans for revenge and the ultimate climax where somebo dy or more than one will pay the ultimate price.

The good, the bad, and the ugly Essay Example | Topics and Well Written Essays - 1000 words
The good, the bad, and the ugly - Essay Example These evil things come in different ways, including, ethnicity, race, corruption, sex discrimination, drug abuse and even physical appearance. Occurrences of the wrong doing and evil things in To Kill a Mockingbird further maturity of Scoutââ¬â¢s into a young woman. Representation of Evil according to Plato Plato must have had the love for art work since he talks about them often in his work. He was also perfect in literature style and story-telling; history has it that he was a poet before he met Socrates and became a philosopher. His influence on the western culture is enormous as shown in his work, and this includes Art work and its theories (Ife 30). He also provides a thought-experiment that is shown to teach human beings most of ideas on human nature, and this include our own. When Plato, through his character Glaucon, was discussing the definition of justice with the Socrates, they both try to give their best definitions (Ife 31). Socrates through his character Thrasymachus explains that justice is when the stronger in the society hold their interest, while the young Glaucon argues that more by questioning the commitment of human beings to justice. This story is portrayed as thought-experiment to human beings. ... As a tradition, Gyges was working for the king as a shepherd, and one day there was a strong storm followed by continuous earthquake, which made an opening in the earth at the same spot where Gyges was grazing his flock (Stewart & Levy 198). He jumped into the opening, and to his surprise he saw a body which appeared more than human to him than a stature and it had a glittering gold ring on it. When the shepherds met together to send their monthly report to the king, he became invisible and the other began speaking of him feeling he was not present. Through his powers, he was chosen as a messenger who was being sent to the court, to try and manage to seduce the queen. Moreover he conspired against the king and took over the kingdom (Stewart & Levy 198). This story of the magic ring is important to human beings as it shows what we can do when we acquire power. If it is true that Platoââ¬â¢s allegory of the ring is right, then we should watch consciously when we get power over other s. This mostly relates to politicians whom we give powers, with the expectation that they will do what is right to us (Stewart & Levy 198). Representation of evil in ââ¬Å"To kill a mocking the birdâ⬠To kill a mocking bird explores human morality in the world, shows a perfect conversation in relation to evilness of human beings and inherent goodness. The novel approaches this by dramatizing Scout and Jem at their childhood age. They tend to believed that people are good on earth before they see evil, and transform at the adult stage when they have confronted evil (Bloom 95). In our world today we face numerous things in several forms, including racism, social inequality, discrimination of sex and even physical appearance.

How has information technology changed the daily lives of enlisted men Research Paper
How has information technology changed the daily lives of enlisted men and women serving in conflict zones overseas - Research Paper Example With the aid of academic literatures, this paper also aims to define information technology as used in this paper to provide a background as to how information technology relates to the US military, and provide a historical background of the utilization of IT in the US military forces to probe on how technology has affected military forces across different eras. 2.0 Information Technology (IT) Generally, Information Technology or IT is the processing of information by the computer systems which are greatly used for communication, data security and storage (Stoyles, Pentland, & Demant, 2003, p. 4). Thus, information technology helps the people in gathering, sharing and storing of data in a convenient and fast manner. Moreover, according to Yadav (2006, p. 2), information technology includes television sets, published works, computers and the Internet (which are common technologies used at home and offices) and any other media platforms where people can acquire information. In the cont ext of the military forces, information technology relates to the Revolution in Military Affairs (RMA) wherein information technology is used for weaponry, surveillance mechanisms, processing of information, and organizational transformations of different military units (Goldman, 2005, p. 1). These benefits center on the organizational advantage of the force. Part of the utilization of information technology of the US corps is also to provide personal benefits to the military soldiers as privatization of housing through IT, skills development and telemedicine programs. 3.0 IT and the Military: History In the early days of war fighting, various nations have adopted new technologies that brought radical changes in fighting. The end of World War II has marked the birth of atomic bombs where it was later developed to hydrogen bombs (Perry, 2004, p. 235). As people become more knowledgeable on the use of technology, the weapons and war instruments have also metamorphosed to a more advanc ed state. Furthermore, as the Soviet Union and the United States of America are creating war technologies based on fatal situations, both countries have developed missiles (Perry, 2004, p. 235). War weaponry continuously evolved which now includes new systems as satellites, smart sensors and new aircrafts to name a few. However, during the 1990s, as information technology slowly shapes the American society, and likewise, the US military has also acknowledged the importance of such technological advancement to further develop its strategies and principles that will ensure the dominance of the forces of the US military (Dombrowski & Gholz, 2006, p. 1). As information technology in the military forces centers on the war fighting improvement, they have implemented ââ¬Å"network-centric warfare,â⬠thereby providing a centralized infrastructure that allows communication, detection mechanics, commanding and controlling systems, combat information and battleground bearings among other s that can be accessed by various military personnel (X. Wang, Wei, & H. Wang, 2012, p. 573). From the mechanical war instruments, the advent of more advance technologies paved way for the

Assignment on us history Example | Topics and Well Written Essays - 500 words
On us history - Assignment Example All the more along these lines, we verbalize that the outlaw laws requires the way that the profit of slaves "for ache of overwhelming punishment" is acknowledged yet allowed a jury trial under the condition that outlaws be restricted from affirming with all due respect (Gordon, 2013). Because of this and thinking about the historical backdrop of west domains possessed by the slaves, being a stakeholder I feel that slaves dont possess and additionally propose to o claim any slaves and hence the bearings could be viewed as invalid and void. The War of 1812 was, it could be said, a second war of freedom, for before that times the United States had not been concurred fairness in the group of countries. With its decision, a large number of the genuine challenges that the adolescent republic had confronted since the Revolution now vanished. National union under the Constitution brought a harmony between freedom and request. With a low national obligation and a landmass expecting investigation, the possibility of peace, success and social advancement opened before the country. Pondering the part of the uncovered framework, the position of the central government at this point is incredibly reinforced by a few Supreme Court choices as saw from the way that a conferred Federalist, John Marshall of Virginia, got to be head equity in 1801 and held office until his demise in 1835. Subjection, which had up to now have gained minimal open consideration, started to expect much more amazing vitality as a national issue. In the early years of the republic, when the Northern states were accommodating prompt or progressive liberation of the slaves, numerous pioneers had assumed that bondage might vanish. In 1786 George Washington composed that he passionately longed some arrangement could be embraced "by which bondage may be abrogated by moderate, beyond any doubt and subtle degrees. The desire from that point forward have been turned out to

Determination of Vitamin C Content in Foods
Determination of Vitamin C Content in Foods Zheng Xiao Introduction Vitamin C, also known as L-ascorbic acid, is an essential component of our diets. It is a good antioxidant, a key component that helps to prevent damage to proteins and deoxyribonucleic acids. In the food industry, vitamin C is added to increase the nutritional content of food products and also for preservative purposes. As the human body is unable to synthesise vitamin C, it would have to be consumed as part of our diet. Fresh fruits and vegetables for instance are common sources of vitamin C. Vitamin C is a labile compound and is easily degraded by enzymes and atmospheric oxygen. Its oxidation can be accelerated by excessive heat, light, and heavy metal cations (Pisoschi, Danet, Kalinowski, 2008). During the manufacturing process, some vitamin C would be lost. Thus, in fruit juice products, vitamin C level is commonly used as a gauge for quality. This prompts manufacturers to fortify their products with high levels of vitamin C to ensure that sufficient vitamin C is present in the product throughout the storage process. Due to the wide use of ascorbic acid in both food products and in the pharmaceutical industry, many analytical methods exist for the determination of ascorbic acid, including titrimetric, spectrophotometric and chromatographic methods, each with their advantages and disadvantages. An example of a titrant used is 2,6-dichlorophenolindophenol (DCIP), which will oxidise the ascorbic acid that is present in the sample. While titrimetric methods are simple to use, they are also known to overestimate the amount of ascorbic acid present due to the presence of oxidisable species other than ascorbic acid (Hernà ¡ndez, Lobo, Gonzà ¡lez, 2006). In addition, many interferences often occur with coloured samples (Arya, Mahajan, Jain, 2000). An example would be the masking of colour change at the end point of titration by highly coloured extracts from fruits and vegetables (Eitenmiller, Landen, Ye, 2007). Spectrophotometric methods work by determining the absorbance of vitamin C which is compared against standard concentrations. However, such methods are susceptible to possible interference due to absorbance exhibited by other components that is present in the sample matrix. Lastly, chromatographic methods are commonly used because of their simplicity, short analysis time and sensitivity (de Quirà ³s, Fernà ¡ndez-Arias, Là ³pez-Hernà ¡ndez, 2009). The sample is separated into its components based on their relative affinity with the mobile and stationary phase. Reversed-phase high performance liquid chromatography (RP-HPLC) for instance is a very efficient method that is used in ascorbic acid analysis of fruits, vegetables and beverages. Ascorbic acid is relatively hydrophilic due to the presence of several hydroxyl groups. Thus, it has a higher affinity to the polar mobile phase than the non-polar stationary phase, allowing it to be separated from the other components in a sample. The retention time gives a qualitative analysis of the sample while the area under the peak allows for the quantitative determination of ascorbic acid content present. However, a major disadvantage of this method is its high cost compared to other conventional methods. The objective of this experiment is to determine the ascorbic acid content in commercial guava juice by RP-HPLC. Materials and Methods The product analysed was commercial guava juice. The experimental procedure was as stated in the laboratory manual, with the slight amendments as follows. The filtrate (2mL) from the centrifuged sample was diluted (1 part sample: 4 part acetic acid) with 2% acetic acid. Five sets of standard ascorbic acid solutions were prepared (40ppm, 80ppm, 120ppm, 160ppm and 200ppm for each set) using a stock solution (1000ppm ascorbic acid) and 2% acetic acid for dilution. The standard solutions were filtered using the 0.45 micron cellulose acetate syringe filter, beginning with the lowest concentration. The column used was a Phenomenex Ultrasphere 5u C18 column (1504.6mm) and the wavelength used was 254nm. Results and Discussion A calibration graph was plotted (Figure 1) using average peak area (Table A1 in appendix) for standard solutions versus their respective concentrations. For each standard solution, four duplicates were prepared. This was done to increase the accuracy of the calibration curve. The r2 value obtained (0.9984) was close to the ideal value 1, indicating a good linear correlation between the area under peak of interest and ascorbic acid concentration. This allows good estimates of ascorbic acid content to be made given the area under peak of interest for each sample. Table 1. Ascorbic acid concentration in samples prepared by Groups 10 to 18 Sample calculation for Group 11: Ascorbic acid concentration in diluted sample = = 116ppm Ascorbic acid concentration in original sample = 116ppm 5 = 581ppm = 58.1 mg / 100mL of juice Average ascorbic acid concentration in original sample = =58.0 mg / 100mL of juice The average retention time of the samples prepared by different groups was 2.557min (Table A3 in Appendix), which is highly similar to that of the ascorbic acid standard solutions was 2.559min (Table A2 in Appendix). This verifies that ascorbic acid was the component analysed. The average ascorbic acid concentration in the guava juice product determined experimentally was 58.0mg/100mL of juice. This was approximately 3.9 times higher than the amount indicated on the packaging (15mg/100mL). As mentioned earlier, As the expiration date is approached, ascorbic acid would be lost to different extents depending on the storage conditions (Kabasakalis, Siopidou, Moshatou, 2000). Manufacturers are known to add ascorbic acid to their products to improve their nutritional value and also to account for the ascorbic acid lost during the manufacturing and storage process (Ottaway, 2008). Since the experiment was conducted before the expiration date of the product (March 14, 2014), a higher ascorbic acid content would be expected. The original ascorbic acid concentration for group 14 was excluded from the calculation as it was almost double of other results and thus likely to be an outlier. A possible reason might be an error in dilution during the preparation of the sample. The other results were found to be precise with a low standard deviation (1.4) and a low coefficient of variation (2.5%). Conclusion The ascorbic acid content of commercial guava juice determined using RP-HPLC was 58.0mg/100mL of juice. References Arya, S. P., Mahajan, M., Jain, P. (2000).

A braid of loneliness Essay -- Character Analysis, Rayona, Ida
ââ¬Å"The most terrible poverty is loneliness, and the feeling of being unloved.â⬠ââ¬âMother Teresa A Yellow Raft in Blue Water by Michael Dorris is a novel about Native American, narrated by three generations of Indian women; Ida the grandmother, Christine the mother, and Rayona. The stories of three people, ââ¬Å"twisting and tying and blending,â⬠fabricate the braid of their relationship. Each of three strands is a complicated composition of hairlines. There is a hairline that all strands have in common and shape this braid: loneliness. Through the story, loneliness played a crucial part in every characterââ¬â¢s life. It is the important cause of charactersââ¬â¢ action. It shapes the relationship between mother and daughter. Ultimately, oneââ¬â¢s loneliness shapes not only that character, but also affects and causes the loneliness in the next generation. The first character who tells her story is Rayona. Being the last generation, she is in the bottom of the well of loneliness. After her parents separated, Rayona lives with Christine, her mother, who habitually changes her job and moves to the new place. Consequently, she never stays in any schools long enough to make some friends. Her life with Christine is also bitter. In Rayonaââ¬â¢s opinion, Christine does not take care of her much. She said ââ¬Å"I try to recall what Mom says when sheââ¬â¢s sentimental and lonesome: how he was the best one, the only one, because he left her me. How Iââ¬â¢m her sterling silver lining, the one whoââ¬â¢ll never leave her like he did. Like she did me.â⬠(64) She is disappointed by Christineââ¬â¢s care that exists only in her speech. Lacking of both friends and warm family, Rayona suffered from loneliness. When she goes back to the reservation with Christine to stay with Aunt Ida, Chris... ... ease her with the warmth of my body, to support her with the strength of my arms. But she did not expect this from me, and I did not give it.â⬠The loneliness of mother is the unwanted gift. From generation to generation, the hairlines of loneliness twist and tie the braid of this family. It obstructs the hairline of love. It obstructs the hairline of care. It leads the braid of this family to nowhere. Loneliness is a cell that imprisons motherââ¬â¢s love from reaching the daughter, leaves them feeling unloved, and became lonely. This baneful hairline will continuously distort the braid until they realize. Until they realize that the solution is turning back to face the reality, holding hands and let the truth comes out, then, the three-generation-long loneliness will disappear. The braid will be set in the right shape and tie the family members together with love.

Development And Evaluation Of A Dispersive Liquid Environmental Sciences Essay
It has been developed a small-scale, simple, and rapid diffusing liquid-liquid microextraction ( DLLME ) process in combination with fiber optic-linear array sensing spectrophotometry ( FO-LADS ) with charge-coupled device ( CCD ) sensor profiting from a micro-cell. The official mention methods ( ASTM D2330 ââ¬â 02, ISO 7875-1 ) which require boring processs were replaced with modified method, as a consequence, it has achieved a major decrease in sample size, riddance of the usage of expensive glasswork, and a lessening in the measure of trichloromethane used every bit good as much more addition in sensitiveness. Our presented method requires merely one twentieth of sample ( 5.0 milliliter ) , less than one three-hundredth of microextraction dissolver ( chloroform = 138 Aà µL ) , and much reduced in analytical clip compared with official analytical methods ( less than one minute ) . The standardization curve was additive in the scope of 0.06 A- 10-1 ââ¬â 0.8 A- 10-1 milligra m La?ââ¬â¢1 of Na dodecyl sulphate ( SDS ) with a correlativity coefficient ( R ) of better than 0.99 and the LOD was 0.02 A- 10-1 milligram La?ââ¬â¢1. The repeatability of the proposed method ( n=7 ) were found to be 4.5 and 3.6 % for the concentration of 0.03 and 0.07 milligram La?ââ¬â¢1, severally. The enrichment factor was found to be 75 for SDS. Keywords: Diffusing liquid-liquid microextraction Aà · Water analysis Aà · Methylene blue active substance Aà · Anionic wetting agent Aà · Fiber optic-linear array sensing spectrophotometry1. IntroductionA turning public concern over protecting our environment obligate chemists, including analytical chemists, to alter their activities in such a manner that they will be conducted in an environmentally friendly mode. Sampling, and particularly sample readying, often involves coevals of big sums of pollutants. This is why sample readying techniques that use a little sum of organic dissolver, or none at all, have been developed [ 1-4 ] . Anionic wetting agents ( AS ) are widely used in family cleaners, industrial detergents and decorative preparations. The wetting agents expelled to natural H2O reservoirs as municipal and industrial wastes are good known to hold inauspicious effects on aquatic beings ; hence the monitoring of wetting agents in environmental samples is of great importance [ 5, 6 ] . For the measuring of entire surfactant concentration, titration methods have been extensively explored [ 7, 8 ] . Several ion-selective electrodes sensitive to anionic wetting agents have been reported so far [ 9-11 ] . Anionic wetting agents are normally determined by spectrophotometric methods utilizing methylene blue ( MB ) , this standard methods being used to find AS in the surface and tap-water samples ( ASTM D2330 ââ¬â 02, ISO 7875-1 ) [ 12, 13 ] . The method is based on the formation of blue-coloured trichloromethane extractible ion-pair between the AS and the cationic MB. This requires three consecutive extractions of AS-MB content in 100 milliliter of sample with 15, 10, and 10 milliliter of trichloromethane. The ion-pair is determined by spectrophotometry, mensurating the optical density at 650 nanometer. However, these official methods are non merely long and boring but besides require great measures of sample and trichloromethane which has harmful consequence on chemists and environment. Besides, this method needs batch of research lab glasswork, do these operations highly expensive and uncomfortable for the operator. So it seems necessary to seek for new offers as options for the a foresaid method in order to increase the laboratory productiveness, operator safety, comfort, and to cut down drastically the reagents ingestion and waste production. Koga et Al. proposed a decrease of the size of sample employed for AS finding in H2O, being modified this method to utilize 50 milliliter of H2O and 5 milliliter trichloromethane, holding obtained a six times addition of the research lab productiveness [ 14 ] . An other simplified methods that cut down the measures of reagent by utilizing a certain sort of adsorbent have been proposed [ 15 ] . However, this method besides involves boring processs. Besides other research workers studied primary biodegradation of AS in aerophilic showing trials based on the formation of ion-pair of AS and MB [ 16 ] . By early 2006, Assadi and his research group innovated an attractive, high public presentation and powerful liquid-phase microextraction ( LPME ) method which named their techniques ââ¬Å" Diffusing liquid-liquid microextraction â⬠( DLLME ) [ 17-19 ] . Beyond the trait of simpleness of operation and celerity, ingestion of microextraction dissolver at the micro-level volume and compatibility with analytical instruments are other profitable characteristics of DLLME as a sample pretreatment method [ 20-25 ] For extremely sensitive, accurate, rapid, and cheap measuring with ingestion of extraction dissolver at micro-level volume, we propose a simplification of the spectrophotometric MB method that can be utile for finding anionic wetting agents in aqueous samples. A consecutive DLLME in combination with fiber optic-linear array sensing spectrophotometry ( FO-LADS ) with charge-coupled device ( CCD ) sensor profiting from a micro-cell was used for this intent.2. Experimental2.1 Reagent and criterions The reagents used in the experiments were of analytical class: MB ( used as a cationic dye ) , sodium dodecyl sulphate ( SDS, employed as a representative anionic wetting agent ) , acetone as disperser dissolvers, trichloromethane as microextraction dissolver, NaOH, HNO3 ( 65 % ) , HCl ( 37 % ) , acetic acid, and Na ethanoate for doing buffer solution ) and obtained from Merck ( Darmstadt, Germany ) . Absolute ethyl alcohol ( & gt ; 99.6 % ) purchased from Bidestan company ( Qazvin, Iran ) . The needed measure of SDS was dissolved in pure H2O to do standard solution of 1000 mg L-1. The stock solutions of MB ( 3 A- 10-3 mol L-1 ) were prepared by fade outing appropriate sums in dual distilled H2O. All the plastic and glasswork were cleaned by soaking for 24 H in 10 % v/v HNO3. After cleansing, all containers were exhaustively rinsed three times with dual distilled H2O and twice with acetone prior to utilize. No any detergent was used to clean glasswork because it is hard to take from surfaces and causes high consequences. 2.2. Apparatus and Instrumentation apparatus The fiber optic-linear array sensing spectrophotometer was perched from Avantes ( Eerbeek, Netherlands ) . The light beam from the UV-Vis beginning ( Deuterium-Halogen ) was focused to the sample micro-cell ( Starna Scientific, Essex, England, Cat. NO. 16.40F-Q-10/Z15 ) . The spectrograph accepts the light beam transmitted through the optical fibre and disperses it via a fixed grate across the 2048 component CCD-linear array sensor. The instrumental parametric quantities are listed in Table 1. A Universal EBA 20 extractor equipped with an angle rotor ( Angle rotor for 8 A- 15 milliliter tubings, 6000 revolutions per minute, Cat. No. 2002 ) were obtained from Hettich ( Kirchlengern, Germany ) . An adjustable pipette ( 10-100 Aà µL ) was prepared from Brand ( Wertheim, Germany ) . All 0.1, 1.0 and 2.5 milliliter panpipes were prepared from Hamilton ( Reno, NV, USA ) . To clean out the micro-cell, avoid any memory consequence and better the repeatability of process, it was washed three times by about 2 milliliters of propanone between each analysis and dried with a watercourse of cold air by usage of a hair drier. 2.3. Mention process Hundred milliliter of sample was placed into a 250 milliliter dividing funnel and 10 milliliter of a 1 A- 10a?ââ¬â¢3 mol L-1 MB solution and 15 milliliters trichloromethane were added. After agitating the mixture smartly for 1 min, the two stages were let to divide and chloroform bed taken for analysis. Each sample was extracted to boot two times utilizing 10 ml part of trichloromethane and optical density measurings were made at 650 nanometers in forepart of an external standardization prepared from SDS. Solutions in the scope between 0.1 and 0.5 milligrams La?ââ¬â¢1 were extracted in the same manner than samples. 2.4 Recommended analytical process Into a series of screw cap glass trial tubing with conelike underside 5.0 milliliter of the standard SDS solutions at the concentration in the studied scope were pipetted out. Then 25 Aà µL of 3 A- 10-3 mol L-1 MB standard solution was added. Afterwards, 2.00 milliliter ethyl alcohol ( disperser dissolver ) incorporating 138 Aà µL trichloromethane ( microextraction dissolver ) was injected quickly into the sample solution utilizing a 2.50-mL syringe. This injection led to a cloudy solution, caused by the all right droplets of trichloromethane into the aqueous sample. The stage separation was accelerated by centrifugating at 5500 revolutions per minute for 3 min. After this measure the spread all right droplets of trichloromethane were settled at the underside of the aqueous solution in conelike trial tubing. Subsequent to this process, for evacuating the upper aqueous solution a long needle connected to 10-mL injection syringe was immersed down in to prove tubing and pulled the spe culator up till minute 200-300 Aà µL of aqueous stage remains at the top of organic bed. The volume of the settled organic stage was determined utilizing a 100-i?à L microsyringe at 25 à °C which was 65Aà ±2 Aà µL. Sixty micro-liter of this settled stage was removed by micropipette and introduced into micro-cell. The ordinary optical density of AS-MB ion-pair in trichloromethane was measured at the wavelength of 650.0 nanometers by agencies of FO-LADS.3. Result and treatmentIn order to obtain a high sensitiveness, the parametric quantities impacting the DLLME such as the type of the microextraction and the disperser dissolvers every bit good as their volume, concentration of MB, pH, and the microextraction clip were optimized. The enrichment factor ( EF ) was defined as the ratio of the analyte concentration in the settled stage to the initial analyte concentration in the aqueous sample. The analyte concentration in the settled stage was calculated from the standardization graph obtained by the conventional liquid-liquid extraction ( LLE ) /FO-LADS ( extraction conditions: 2.0 milliliters standard H2O sample in the concentration scope of 4.5 A- 10-4 ââ¬â 1.5 A- 10-3 mol L-1 of MB and 1.5 ââ¬â 5.0 mg L-1 SDS which extracted with 2.0 milliliters trichloromethane ) . 3.1. Chemical reaction of SDS and MB The equilibrium between SDS, MB and the distribution of SDS-MB ion-pair in H2O and trichloromethane has been qualitatively reported in the literature [ 14 ] . The AS dissolved in H2O are somewhat soluble in trichloromethane. On the other manus, MB dissolves good in both, trichloromethane and H2O, supplying a bluish colour solution in all the instances. When pure H2O is assorted with a chloroform solution of MB, the bluish colour is quickly transferred to the aqueous stage. 3.2. Consequence of ion-pair formation status parametric quantities The overall ion-pair formation status of SDS and MB is concentration of each, pH every bit good as clip needed. Our efforts were chiefly centered on optimising these parametric quantities under our microextraction conditions ( DLLME ) . In this survey the clip required for ion-pair formation were tested between 0 sec -10 min. The consequences, deducing from the ion-pair formation utilizing different reaction times, exhibited that the reaction clip has no any consequence on ion-pair formation efficiency and longer clip period did non better the reaction. In order to find the optimum pH for the ion-pair formation, several sample pH values were varied from 2.5 ââ¬â 7.5 to prove the ion-pair formation of AS and MB in 5.0 mL H2O samples incorporating 0.04 mg L-1 SDS and extra sum of MB. The highest microextraction efficiency was achieved in the pH of studied scope and we found that in the alkalic solution MB it self would pull out into trichloromethane in absence of any MBAS. In optimisation processs no any buffer solution were used because after adding reagents the pH of solution become somewhat acidity in coveted scope. The influence of the MB concentration on the ion-pair formation/microextraction efficiency was performed in the scope of 0 ââ¬â 2.1 A- 10-5 mol L-1 while the concentration of SDS was 0.04 mg L-1. During the fluctuation of this concentration the other experimental variables remained changeless. The consequences demonstrated that by increasing the MB concentration up to 1.5 A- 10-5 mol L-1 the microextraction efficiency increased and, so, no fluctuation were observed ( as depicted in Fig. 1 ) . Sing the fact that proposed method is additive up to 0.08 milligrams L-1, hence, the sum of 5 A- 10-5 mol L-1 MB was selected as consider adequate surplus sums. 3.3. Influence of the microextraction dissolver sort and volume The choices of an appropriate microextraction dissolver have a high importance function to acquire a high sensitiveness DLLME, so sort and volume of it were studied and optimized. Microextraction dissolver should hold particular features in DLLME ; it should hold really low solubility in H2O, extraction capableness of interested compounds, and much denseness than H2O. Chloroform and C tetrachloride are available as the most celebrated microextraction dissolvers in DLLME. During our primary surveies we found that C tetrachloride is non capable to pull out the ion-pair of SDS-MB at all. Furthermore, the recommended dissolver in the standard methods is trichloromethane ; hence, it was our extinguished pick. To look into the consequence of microextraction dissolver volume, experiments were performed by utilizing 2.00 mL ethyl alcohol incorporating different volumes of trichloromethane ( 138, 143, 148, 153, 158 and 163 i?à L ) . By increasing the volume of trichloromethane from 138 to 163 Aà µL, the volume of the settled stage additions about from 65 to 90 Aà µL. Harmonizing to consequences ( Fig. 2 ) , optical density lessenings with increasing the volume of trichloromethane ; it is clear that by increasing the volume of trichloromethane the volume of the settled stage additions. Subsequently, at low volume of the microextraction dissolver high optical density or enrichment factor was obtained. 3.4. Influence of the disperser dissolver sort and volume In DLLME, choosing an appropriate disperser dissolver is of import, since disperser dissolver should be mixable with both microextraction dissolver and aqueous sample. For the interest of geting the most suited disperser dissolver, two sorts of instead safe disperser dissolvers: propanone and ethyl alcohol were studied. A series of sample solutions were studied by utilizing 2.00 milliliter of each disperser dissolver incorporating 138 Aà µL of trichloromethane and the enrichment factors were investigated. The consequences showed that ethyl alcohol showed much better efficiency than propanone ( enrichment factor of 75 and 17, severally ) . Less toxicity and the higher microextraction efficiency of ethyl alcohols make it a better pick. After taking ethanol as disperser dissolver, it is necessary to optimise the volume of it. The influence of the disperser dissolver ( ethanol ) volume on the microextraction efficiency was tested over the scope of 0.50 ââ¬â 2.00 milliliter, but the fluctuation of the ethyl alcohol volume ( disperser dissolver ) caused alterations in the settled stage volume. Hence, it was impossible to see independently the influence of the ethyl alcohol volume on the microextraction efficiency in DLLME. To avoid this job and in order to achieve a changeless volume of the setteled stage, the ethyl alcohol and trichloromethane volumes were changed at the same time. The experimental conditions were fixed and included the usage of different ethanol volumes: 0.50, 1.00, 1.50, and 2.00 milliliter, incorporating 97, 102, 121, and 138 I?L of trichloromethane, severally. Under these conditions, the settled stage volume remained changeless ( 65 Aà ± 2 I?L ) . Fig. 3 shows the curves for optical density o f SDS-MB ion-pair versus the volume of ethyl alcohol. The optical density increased, when the ethanol volume increased from 0.50 to 2.00 milliliter of ethyl alcohol as disperser dissolver. Harmonizing to the consequences, a 2.00 milliliter ethyl alcohol was chosen as the optimal disperser dissolver volume. 3.5. Influence of the microextraction clip Microextraction clip ( interval clip between the injection of a mixture of disperser dissolver and microextraction dissolver, before get downing to centrifugate ) is of import factor that may be effects microextraction efficiency of analytes from aqueous stage to organic stage. The fluctuation for microextraction efficiency of SDS-MB as a map of microextraction clip was studied in the scope of 5 unsweet ââ¬â 10 min. The ensuing informations, exposing that the microextraction clip has no important consequence on the microextraction efficiency for the mark compound. It was revealed that after the formation of the cloudy solution, the contact country between the microextraction dissolver and the aqueous stage was well big, defining why the extraction equilibrium could be established really fast. In this method the most time-consuming process was centrifugation of the sample solution in the microextraction process, which was about 3 min. Sing the fact this period of clip ( 3 min ) is for eight trial tubing ( microextraction vass ) , the clip required for managing one trial tubing is less than 25 seconds. 3.6. Analytic features of the method To measure the practical pertinence of the proposed DLLME/FO-LADS technique for finding of MBAS in H2O samples, several analytical public presentation features such as enrichment factor, one-dimensionality, bound of sensing ( LOD ) and repeatability were investigated under optimized conditions. The standardization curve was additive in the scope of 0.06 A- 10-1 ââ¬â 0.8 A- 10-1 milligram La?ââ¬â¢1 of SDS with a correlativity coefficient ( R ) of better than 0.99. The LOD, defined as CL =3 SB/m ( where CL, SB and m are the bound of sensing, standard divergence of the space and incline of the standardization graph, severally ) , was 0.02 A- 10-1 milligram La?ââ¬â¢1. The repeatability of the proposed method expressed as comparative criterion divergences ( RSDs, n=7 ) were found to be 4.5 and 3.6 % for the concentration of 0.03 and 0.07 milligram La?ââ¬â¢1, severally. The enrichment factor was found to be 75 for SDS. 3.7. Consequence of diverse ions and application to practical samples Any organic or inorganic compound that will organize a trichloromethane extractable ion-pair with MB will interfere by bring forthing high consequences. These positive intervention include organic sulfonates, carboxylates, phosphates, and phenols, every bit good as inorganic cyanates, chlorides, nitrates, and thiocyanates. On the other manus, any compound efficaciously viing with MB to organize an AS ion-pair will give negative consequences. These negative interventions cause by some aminoalkanes and have analytical significance in the instance of quaternate ammonium compounds. For pretreatment of MBAS in all Waterss and waste Waterss that contain meddlesome substances the undermentioned process is recommended by ASTM mention method. The selected sample is hydrolysed by boiling under partial reflux with hydrochloric acid. The residuary merchandises are neutralized to a controlled pH value, and reacted with 1-methylheptylamine. The resulting ion-pairs are extracted into a trichloromet hane stage and evaporated to dryness on a steam bath. The amine constituent of the ion-pair is removed by boiling in an aqueous alkaline media and the stray MBAS are so determined under the described mention process. Besides other research workers examined the consequence of assorted diverse ions on the finding of AS by similar method [ 14, 6 ] . In order to set up the cogency and pertinence of proposed method, it was applied to the finding of AS in several existent H2O samples ( mineral, pat, and good H2O samples ) by proposed method. For this intent, 5.0 milliliter of each sample was preconcentrated utilizing DLLME technique as described before ( pH was adjusted with acetic acid/sodium ethanoate buffer if necessary ) . In order to measure matrix consequence, the standard add-on method was applied for the finding of AS ( at spiking degrees of 0.02 and 0.05 mg L-1 ) in spiked existent samples which the comparative recoveries of analytes are mentioned in Table 2. The obtained consequences were compared with those obtained from spiked distilled H2O. In all instances, the spike recoveries confirm the dependability of the proposed method. The obtained comparative recoveries indicates that matrix does non act upon the microextraction efficiency in the mentioned samples ( no serious interventions ) , hence, there was non any duty t o take interventions. As it can be seen in table 3, the public presentation of proposed method shows distinguishable advantages over other methods with mention to try volume, extraction dissolver volume, RSDs, LODs and additive dynamic scopeDecisionsThis survey demonstrated that DLLME process with really pleasant and robust features for check of AS seems to offer possible campaigners for mention method, which utilizes really little sum of microextraction dissolver every bit good as its low cost. Furthermore, freshly DLLME process in combination with FO-LADS equipped with charge-coupled device ( CCD ) sensor profiting from a micro-cell demonstrated that LPME ( DLLME ) could be combine with spectrophotometer system despite of micro-level sample volume without any dilution and diminishing the sensitiveness. Analysis of several existent samples for AS content illustrated the truth, dependability, simpleness, dependability and bargain rate of method. It appears to be a time-saving techni que, chiefly for research labs executing analysis of a big figure of samples with a rapid coverage clip. Besides we suggest the pertinence of this method for supervising the biodegradation of AS.

Adeline Yen Mah Essay Example
Adeline Yen Mah Essay Example Adeline Yen Mah Paper Adeline Yen Mah Paper Some readers might say Adeline had presented a picture of childhood which was consistently unhappy? Do you agree? Chinese Cinderella is about a young girl battling through life and many misfortunes to finally get a good future, which she gets through sheer perseverance. I believe that Adeline Yen Mah does have a terrible childhood which consists of mainly sorrowful situations; but her being an optimistic child; she is able to transform little actions into something she can find pleasure from. Therefore in this essay I will discuss how I disagree with the statement Some readers might say Adeline had presented a picture of childhood which was consistently unhappy, as I believe that however rarely it took place there were a few happy situations. I will also try to discuss the idea of how each of these happy situations are transformed each time into depressing situations. The story begins with an enthusiastic child, overjoyed by the recent events where she was awarded a prize at school. She is then delighted about the fact that her dearly loved Aunt Baba would keep her certificate in the same box in which she kept her truly, valuable, possessions, as if her award were also some precious jewel impossible to replace. Therefore I believe she did have moments of true happiness but they were short-lived as these emotions are soon distorted by the adversity she received through her family. For example we are then informed of the sad matter of how no one goes and visits her at school when she receives theses prizes. In this same scene we find out how Adelines own sister blamed her, a four year old child, for the death of their mother. If you had not been born Mama would still be alive. I feel that this show the true extent of how horrible her family were to her and how lonely she may have felt throughout life. Soon after, because of the Japanese invasion, Adeline moves with her family to Shanghai, where she is enrolled into another school. She was excited yet nervous. But again her emotions are quickly transformed into the feeling of resent as she realises that no one had made plans on how she was to travel to and from school. After getting lost she phones home and realises no one had missed her. This again shows how her happiness is always short-lived. Rules basically form our lives. The rules that Adeline has to live with are truly unpleasant and her life is very restricted. She is not given any pocket money, tram fare, or new clothes. This shows her life in general was not a chain of happy events and did consist of misery. An important event to consider was when we are told that the children had been looking forward to Chinese new year for weeks and their new outfits. Again, this however small it may be his is obviously something that Adeline found pleasure in, or it would have been if she didnt get a basic, brown smock mode of material left over from one of big sisters garments. This shows she is not considered nearly as important as Niangs biological children, who get beautiful new clothes in all occasions. All throughout the story it is very clear to see there is a very apparent division between Niangs children and Adelines brothers and sister. Niang and her biological children live on the first floor, unlike Adeline and brothers and sisters who are to live on the second floor. Adeline and the others are not allowed to step foot on the first floor yet Niang can enter their rooms at any time to inspect it. This is Niangs way of showing authority in the family as they now live under her roof, and therefore her rules. Even though Adeline and her siblings were treated poorly by their parents, in chapter 9 her and her siblings unite together to organise themselves against Niang, even though the plan does not go ahead, the actuality that she is finally part of a family or a group obviously means a lot to her, yet this diminutive bit of happiness which she holds onto is taken by her own brothers who play a revolting prank on her where they trick her into drinking their urine. This scene tells us that, all that Adeline really wants is to be accepted, she wants to be part of something, and not have to be alone. I hope I have been able to show you clearly how it is that Adeline does have moments of happiness however small they may be but the point I am trying to make is that they are short lived and soon turn into a miserable situations. Each happy memory so far clearly turns into a heartbreaking, demoralizing situation. Another memory which is hastily transformed into a depressing remembrance is when Adeline was given a pet duckling known better as P. L. T.
