The Tragedy Of Agamemnon By Sophocles Essay - 1800 Words
When discussing Greek tragedies, there is a theme of anger and revenge that is somewhat underling in many texts of this tragic nature. In Agamemnon by Aeschylus the main character Agamemnon faces these constructs head on mostly as a direct result of his decision to sacrifice his daughter. However, this is not the only case where anger and revenge is exhibited in the tragedy of Agamemnon as in truth it runs rampant throughout the text. Another tragedy that exhibits these traits is that of Medea written by Euripides. The central character Medea was abandoned by her husband Jason and resultantly she made a choice to pursue a revenge plot against Jason that entailed the murder of their children. An interesting parallel between these texts is the role that children played in these pursuits of anger and revenge. What this really shows about Greek tragedies is the strong role of family that is present when it comes to tragic events that are generally resultant of anger which can then lead t o revenge and thus death, hence perhaps why such works are referred to as tragedies. In Agamemnon, the main character Agamemnon was headed off to the well-known Trojan war when he encountered strong winds sent by the goddess Artemis. Rather than abandon the war and turn back Agamemnon made the choice to sacrifice his daughter Iphigenia to please Artemis so he could go on his way. However, by making this decision Agamemnon unwittingly planted the seeds of revenge in his wifeââ¬â¢s heart that wouldShow MoreRelated Destiny, Fate, Free Will and Free Choice - Prophecies in Oedipus, Antigone, and Agamemnon1008 Words à |à 5 PagesProphecies in Oedipus, Antigone, and Agamemnonnbsp;nbsp;nbsp;nbsp;nbsp; nbsp; Oracles, seers, and prophets are used in Greek tragedy to provide foreshadowing for the audience and characters.

Book Thief free essay sample
Analyse how an important event at the beginning shaped outcomes in an extended written text. In the book ââ¬ËThe Book Thiefââ¬â¢, Markus Zusak the author has used the theme of colours in the prologue. The theme of colours has been used to show how Death sees colours and what these colours mean to Death in his perspective. Markus Zusak uses the techniques of imagery to show this. We also see Deaths perspective on humanity, how he dislikes humans, their behaviour, their thoughts, their actions, this is where the theme of duality of human is shown. The voice of Death is the main technique, Deathââ¬â¢s voice is throughout the book, and this technique also collides with the theme of duality of humans. Setting is a strong technique in the book as well as it is set in 1945 during the Holocaust ââ¬Å"where death was everywhereâ⬠. Markus Zusak the author of ââ¬ËThe Book Thiefââ¬â¢ uses the technique of colours in the prologue, the narrator Death introduces himself in four parts and the first one is ââ¬ËDeath and Chocolateââ¬â¢ In this part Death tells us the importance of colours and how he sees colours. Death looks at colours as a distraction from the tortured suffering survivors of the dead: ââ¬Å"I do, however, try to enjoy every colour I seethe whole spectrum It takes the edge off the stress. It helps me relax. â⬠ââ¬Å"First the colours. Then the humans. Thatââ¬â¢s usually how I see things. Or at least, how I tryâ⬠Death tells us that he sees the colours first before seeing the dead human, he explains that he deliberately tries distract himself from the humans to the colours, its way of distracting himself because itââ¬â¢s in his nature, his line of work and then later he says ââ¬Å"A colour will be perched on my shoulder. I will carry you gently away. â⬠ââ¬Å"The question is, what colour will everything be at that moment when I come for you? What will the sky be saying. Personally, I like a chocolate-coloured sky. Dark, dark chocolate. People say it suits me. â⬠This tells us that Death looks at colours as a distraction from the suffering survivors of the dead: I do, however, try to enjoy every colour I seethe whole spectrum It takes the edge off the stress. It helps me relax. Death describes the murkiness of the colours and how they run into each other, one after another. In the second part of the prologue ââ¬ËBeside the Railway Lineââ¬â¢ the colour it opens with is white, emphasis on the blinding snowy setting but also the death of the boy and the purity of the girl, the book thief, Liesel the perpetual survivor. We can tell this because the colour white is being used and white is pure, and ââ¬Å"white is without a question a colour. â⬠This was the first time death saw the book thief. Next section is ââ¬ËThe Eclipseââ¬â¢ ââ¬Å"Next is a signature black, to show the poles of my versatility, if you like. It was the darkest moment before the dawn. â⬠The colour used to show, to outline Deaths job, to show his ability. This is where he saw the book thief again. And the last is ââ¬ËThe Flagââ¬â¢ with the focal colour red, a soupy tomato red, this was the last time Death saw the book thief, during the bombing Death saw the girl kneeling in the street hold the book to her chest, Death remembers the book thief in colours, primarily in red, white and black, Death combines these colours into the Nazi flag: a black swastika in a white circle surrounded by a field of red, an implication is that Nazism was responsible for the deaths in these three episodes. Death also tells that he observes ââ¬Å"a multitude of shades of intonations, that a single hour can consist of thousands of different colours. â⬠Deaths willingness to observe different shades in the colour spectrum indicates Deaths basic uncertainty about whether the human race is totally good or totally evil, suggesting that in Deaths analysis, human beings are at various times capable of being either good or bad, this is where the theme duality of humanity comes in. Markus Zusak uses the theme of duality of humanity, how Death dislikes humans, their thought, and their actions but then he realises that not all humans are the same he tells us to ââ¬Å"prove to me that you and your human existence, are worth it. â⬠In the first section ââ¬ËDeath and Chocolateââ¬â¢ we see that Death describes humanââ¬â¢s murkiness and how they run into each other, one after another. Death describes himself as affable and then he tells us that he not nice, itââ¬â¢s not in his line of work to be nice. ââ¬Å"Here is a small fact. You are going to die. â⬠This shows us that Death is very straight forward, very frank and honest when he tells humans that they are going to die and then tells us that it is ââ¬Å"nothing to fair. â⬠In ââ¬ËThe eclipseââ¬â¢ death sees a boy taking a teddy bear out of a toolbox and puts it on the pilots chest, and then a crowd appears and the pilots face appeared to be smiling, death calls this a ââ¬Å"final dirty jokeâ⬠ââ¬Å"another human punch line. â⬠To Death this is dehumanization because of their ââ¬Å"dirty joke. â⬠In the last section ââ¬ËThe Flagââ¬â¢ Death takes the book thiefââ¬â¢s book because it was tossed in a garbage truck and carries the stories with him to convince himself of the worth of the human existence. The book thiefââ¬â¢s story is one of those and he want to share it, and this girls story to Death is humanity because she didnââ¬â¢t do a really human thing and was good. Death sees the dehumanization of the Jews in the early stages of the Holocaust. Hitler judging the Jews constantly, taking away their civil rights, and denying that they were even human. Max bitterly remarks that, as a Jew in Nazi Germany, a cold basement is the only place he deserves as he hides from discrimination. In Maxs fantasies of fighting Hitler, he imagines Hitler propagandizing against him, accusing Max personally as a villain and extreme threat to the German people. Deaths sarcastic narration echoes this response. And then we see humanity when Hans gives old Jew that was being sent to a concentration camp a piece of bread, Death narrates: If nothing else, the old man would die like a human. Or at least with the thought that he was a human. Me? Im not so sure if thats such a good thing. Death struggles to understand humanitys capacity for both good and evil. Death is stunned both by the murderous Nazis and mankinds irrational taste for war and by the few human beings who exhibit remarkable compassion and strength, like Hans and Liesel. Wondering if the human race is worth anything, Death is torn by this opposition and cannot reconcile it: I am constantly overestimating and underestimating the human race, that rarely do I ever simply estimate it. Ultimately, Death tells Liesel in the last line of the novel, ââ¬Å"I am haunted by humans. It is the ability of human beings to make different moral choices and the unpredictable decisions that haunts Death. This novel is narrated by Death himself and is told from his point of view so this where the technique of Deaths voice comes . Death spends his time collection humans as they die, this puts him in some very interesting situations sometimes. Wars are busy times for him and he continues to say that he doesnââ¬â¢t understand how humans handle the disappointments of life or why they do the things they do to each other. Death struggles to understand humans and is disgusted with how they behave a lot of the time, so selfish, uncaring and mean. This is one reason why the Book Thief stands out to him so much to Death, because of the tragic experiences of her life is different from a lot of humans. In the first section Death starts with a sarcastic and bluntly dark tone in addressing the readers and describing his work, throughout the rest of the book Deaths narration is less affected and turns into ââ¬Ëthird person subjectiveâ⬠Markus Zusak uses the technique of setting in WWII, Nazi Germany ââ¬Å"where death was all around us at that timeâ⬠Molching, Germany, more specifically on Himmel Street. Himmel which translates into Heaven and ââ¬Å"whoever named Himmel Street certainly had a healthy sense of irony. Not that is was a living hell. It wasnââ¬â¢t. But it sure as hell wasnââ¬â¢t heaven, eitherâ⬠. Himmel Street is where the Hubermanns live, along with Leisel, the book thief and pretty much all of the story takes place on or around this street. Nazi Germany was used because of the terrible things happening at that time. Markus Zusak said in his interview ââ¬Å"who better to tell the story in the book set in Nazi Germany because Death was everywhere at that time and place. â⬠But not only bad things happened at that time and place there where moment where Death tried ââ¬Å"to find beautiful moments in a ugly timeâ⬠such as when Hans Hubermann gave a piece of bread to an old Jew, such also show his humanity. In conclusion the author used the themes of colours, the theme of duality of humanity, the technique of Deathââ¬â¢s voice and Setting to show us ââ¬Å"beautiful moments in a ugly timeâ⬠and good and evil in humans.

How different concentration of enzyme catalase affects the rate of breaking down substrate hydrogen peroxide Essay Example
How different concentration of enzyme catalase affects the rate of breaking down substrate hydrogen peroxide Essay Example How different concentration of enzyme catalase affects the rate of breaking down substrate hydrogen peroxide Paper How different concentration of enzyme catalase affects the rate of breaking down substrate hydrogen peroxide Paper Enzymes are large proteins that speed up chemical reaction. As globular protein, enzymes have a specific three-dimensional shape which is determined by their sequence of amino acids. Despite their large overall size, enzyme molecules only have a small region that is functional. This is known as enzymes active site. The substrate molecule is held within the active site by bonds that temporarily form between the R groups of the amino acids of the active site by bonds and all groups on the substrate molecules. This structure is known as enzyme-substrate complex. Enzymes are classified into several categories, such as hydrolytic, oxidising, and educing. Depending on the types of reaction they control. In this case, the enzyme I will use in the investigation is catalase from celery extract, which is concluding as hydrolytic enzyme. This type of enzyme accelerates reactions in which a substrate is broken down into simpler compounds through reaction with adding up water molecules. Oxidising enzyme, known as oxidises, accelerate oxidation reaction; reducing enzyme speed up reducing reactions in which oxygen is removed. A substrate is the molecule, which can bind into the active of enzyme. In this case, I will use hydrogen peroxide as the substrate. Enzyme works in the same way as a key operates a lock. Enzymes active sites have a particular shape like a lock and only a particular key ( substrate) can fit into that lock. Enzymes are therefore specific in the reactions that they catalyse. This is known as the lock and key theory. In practice, unlike a rigid lock, the enzyme actually changes its form slightly to fit the shape of the substrate. In other works, it is flexible and moulds itself around the substrate. As it alters its shape, the enzyme puts a strain on the substrate molecule and thereby lowers its activation energy. In this case, enzyme catalse has a specific active site, which just for the substrate hydrogen peroxide to fit in, then the reaction takes place. The reaction involved is hydrolysis. The equation of reaction is: 2H2O2 2H2O + O2 Factor that would affect the reaction: Temperature At low temperature, the reaction takes place very slowly, this because molecules are moving relatively slowly as have low kinetic energy. Substrate molecules will not often collide with the active site, and so binding between substrate and enzyme is a rare event. Therefore, reaction is slow. A rise in temperature increases the kinetic energy of molecules which therefore move around more rapidly and collide with one another more often. This means at a higher temperature, the reaction will take place faster than a lower temperature and an increasing or a decreasing of temperature will affect my reaction and results. For this reason, I will control this effect by using a water bath to maintain the temperature the same during the whole reaction. As enzyme work best at a certain temperature, this is known as optimum temperature. If the temperature is too low, enzyme cannot work properly; if the temperature is too high, this may denature the enzyme active site and enzyme will lose its function. So to avoid this problem, I will keep the water bath has the temperature of 25?C, which is the room temperature. Therefore enzyme catalase will work properly and temperature will not be a factor to affect this investigation. PH Most enzymes also have an optimum pH at which they function best. In human body, most enzyme work fastest at an optimum pH of about 7. For example, the digestive system Pepsin found in the stomach to digest proteins. A change I pH means a change in the concentration of hydrogen ions in the surrounding of the enzyme. This affects the ionisation of R group in the amino acid residues of the protein molecule and the shape of the active site to bind with the substrate. The lower the pH, the bigger the hydrogen ions concentration it is . Hydrogen ions can interact with the R group of amino acids, affecting the way in which they bond with each other and therefore affect their 3D shape. So the lower the pH, the higher the hydrogen ions concentration it is, and therefore the slower the reaction. Oppositely, the higher the pH, the faster the reaction it will take place. To control this factor, I will keep the pH all the way through the same by using a pH paper to check the pH number during the experiment. Enzyme concentration The rate of reaction increases as the concentration of enzyme increase. Because higher concentration of enzyme means higher number of enzyme molecules, so that more enzyme molecule will collide with substrate molecule, therefore the reaction will take place faster. When there is plenty of substrate, the rate of reaction is not limited by the concentration of enzyme. Therefore if the concentration of enzyme is increased, the number of collision with the substrate molecule and hence the rate of reaction will increase. If the amount of substrate is limited, the rate of reaction decreases because if the amount of substrate is limited, the enzymes active site will not collide with substrate very often, therefore a few products will be made. As the reaction progressing, the substance will be broken down slowly, therefore less substrate left. So enzyme molecules freer, therefore products will be produced more slowly. Hence the slower the reaction goes. In this experiment, the enzyme concentration is an independent variable which I will vary the concentration of celery extract each time to investigate how different concentration of celery extract( enzyme concentration) affect the rate of breaking down hydrogen peroxide. Substrate concentration Increasing in the substrate concentration will increase in the rate of reaction. Because increasing the substrate concentration, we increased the number of substrate molecules; therefore more collision will take place between substrate and enzymes active site. Hence mere products will be produced. Therefore the faster the rate of reaction takes place. However, if we continue increase the substrate keeping the enzyme concentration and volume the same. The rate of reaction will not continue to increase. This is because a higher substrate concentration active site of all the enzyme molecule is busy with substrates. The number of enzyme molecules because a limiting factor. The rate of reaction at higher substrate becomes constant. In this case, I will keep the volume of hydrogen peroxide the same for using each time. Inhibitors Enzyme inhibitors are substances that directly or indirectly interfere with the functioning of the active of an enzyme and so reduce its activity. There are two types of inhibitors: Competitive inhibitors Competitive inhibitors are the molecules which have a shape similar to the substrate, so they fit into the active site of the enzyme. Therefore the substrate cannot enter into the active site and so the enzyme cannot catalyse the reaction. Hence, the reaction is slow down. However, the inhibitors are not permanently bound to the active site and so, when it leaves another molecule can take its place. Sooner or later, all the substrate molecules will find an active site, but the greater the concentration of inhibitors, the longer the reaction will be. Non-competitive inhibitors Non-competitive inhibitors will bind to another part of the enzyme rather than the true active site. This changes the shape of the enzymes active site so that the substrate no longer fits. Therefore the reaction is slow down. As the substrate and the inhibitor are not competry for the same site, an increase in substrate concentration does not decrease the effect of inhibitors. To control the factor of inhibitors. I will not add any substance except celery solution and hydrogen peroxide during the experiment. Prediction I predict that the higher the concentration of celery extract I use, the fast the rate of breaking down hydrogen peroxide I will get. As in higher concentration of celery extract, the more number of catalase molecules in the solution. So there are more collisions between substrate ( hydrogen peroxide) and enzyme( catalase) active site, and more products will be formed( water and oxygen). The rate of reaction can be measured by measuring the volume of oxygen produced in a period of time. The larger the volume of oxygen produced in the same period of time, the fast the reaction is taken place. Preliminary work In order to get finest and reliable results, I did a preliminary work. This enable me not just find out a suitable range of celery extract of catalase concentration I will use in my real experiment, but also help me descried the time interval I will measure the oxygen get and justify the equipment and method. I think these all lead me to get reliable and accurate results in the end. In the preliminary work, I choose to do three different concentration of celery extract. To get different concentrations of celery extract, I used distilled water to dilute the celery extract. I tested the range of celery extract between 100% 20%, the highest concentration is 100%, the lowest concentration is 20% and the median is 60%. The reason I chose these three concentrations is because between each concentration, there is 40% difference and this enable me to test that in which level of concentration, reaction goes best and to find out which concentration of celery extract I will use in my real experiment.

Discussion Board - Assignment Example This simply means that the conditions one experiences in prisons may vary from one place to another. Therefore, asserting that convict criminologists have more credibility in regard to their information of prison life is a farfetched idea. On the other hand, prison is a dynamic place where people get convicted on a daily basis with different criminal offenses. Political systems are also changing on a daily basis meaning that new rules and regulations governing human actions are formulated and implemented each time, thus an action that was not considered a crime in the early 90ââ¬â¢s could be considered a crime in the contemporary society and vice-versa. This creates a need for continuous learning on issues ascribed to prison life, thus one person cannot claim that owing to the fact that he was convicted ten years ago, he is in a better position to comprehend prison-related issues than other scholar.
