Macbeth: The True Nature of Man :: essays research papers

In the play Macbeth by William Shakespeare, the author tries to show the true nature of man by using the play’s main character, Macbeth, as an example. He is overly ambitious, courageous, and self-doubting. Throughout the play, Shakespeare displays these characteristics to the audience through Macbeth to show the true nature of man. At the end of the play, these characteristics ultimately lead to Macbeth’s downfall. In the beginning of the play, Macbeth is described as being â€Å"valiant†. He is a skilled warrior, who is loyal to his king and his country. Almost single-handedly, he wins the war for Scotland. He defeats many of the enemy soldiers, including a traitor, all in the name of his king. But, when three witches encounter Macbeth and his friend Banquo, Macbeth’s ambition begins to grow. They tell Macbeth that he will be Thane of Cawdor and King. Soon after, Macbeth meets with King Duncan. He informs Macbeth that he is the new Thane of Cawdor. Macbeth is astonished, and from then on he is obsessed with being king. His ambition begins to become ruthless when Duncan proclaims that his son Malcolm is the Prince of Cumberland, and therefore, the heir to the throne: â€Å"The Prince of Cumberland! That is a step/On which I must fall down, or else o’erleap, /For in my way it lies. Stars, hide your fires;/Let not light see my black and deep desires:/The eye wink at the hand ; yet let that be/Which the eye fears, when it is done, to see.† (I,iv,48-53) At this moment, Macbeth, realizing that they stand in the way of the witches’ prophecies, decides that both Duncan and Malcolm need to die for him to be king. As soon as Macbeth kills Duncan, he enters into a world of evil. Later in the play, Macbeth’s ambition becomes increasingly ruthless. He kills his best friend Banquo, and almost kills Banquo’s son, Fleance, because he believes they would stand in the way of his reign. The witches told Banquo â€Å"Thou shall get kings, though thou be none.† (I,iii,67) This means that Banquo himself would not be a king, but that his successors would be. Macbeth tries to prevent this by killing Banquo and his son Fleance. Even though Macbeth can be called a tyrant and a murderer, he is nonetheless, very courageous. In the beginning of the play, he fights very bravely for his king and country.

The Adaptation of Archaea to Acidity

The adaptation of archaea in acidic condition. How archaea adapt to acidic environment ? Use variety pH homeostatic mechanism that involve restricting proton entry by cytoplasmic membrane and purging of protons and their effect by cytoplasm. pH homeostatic mechanisms The cell membrane is highly impermeable to protons Membrane channel have a reduced pore size. Protein influx inhibited by chemiosmotic gradient Excess proton pumped out of the cell Cytoplasmic buffering helps to maintain the intracellular pH 1.The cell membrane is highly impermeable to protons High impermeable cell membrane to restrict proton influx into the cytoplasm Example : Archaeal-specific structures composed of tetraether lipids . Thermoplasma acidophilum, Ferroplasma acidiphilum, sulfolobus solfataricus. Factor causing low permeability of acidophile membranes. Monolayer composed of unique â€Å"tetraether lipids† in which two hydrophilic heads attached to the same hydrophobic tail through ether bonds †“ more stable, less fluidBulky isoprenoid core. Ether linkage characteristic of these membranes less sensative to acid hydrolysis than ester linkage. 2. Membrane channel have a reduced pore size. Control size of the entrance to the pore and the ion selectivity at the porin entrance. Control influx of proton across the outer membrane 3. Protein influx inhibited by chemiosmotic gradient Inhibit the influx of protons using a chemiosmotic barrier against the proton gradient (higher ? lower)Chemiosmosis : diffusion of hydrogen ion across the biological membrane via transport protein due to a proton gradient that form on the other side of the membrane. 4. Excess proton pumped out of the cell Active proton pumping Remove excess protons from cytoplasm and balance the pH value in cell. Sequences acidophile genomes have proton efflux systems. 5. Cytoplasmic buffering helps to maintain the intracellular pH Intracellular mechanism help to improve the ensuing biological damage.Cytoplasmic buff er molecules that have basic amino acids capable of sequestering protons. Thus maintain the pH in cytoplasm. References 1. D. B. Johnson, K. B. Hallberg The microbiology of acidic mine waters Res. Microbiol. , 154 (2003), pp. 466–473 2. G. K. Druschel  et al.

Understanding The Hidden Layers And Complexities That Lie...

II. CASE STUDY ANALYSIS: 1. 2. According to Cloke and Goldsmith (2011), â€Å"one way of understanding the hidden layers and complexities that lie beneath the surface of our conflicts is by using the metaphor of the iceberg† (p. 66). Just like an iceberg, there are layers in conflicts. What we see is only a portion of what is happening. Below the water line, is much more. In fact, the portion that we see on the surface is the current issue at hand. The issue is usually easy to observe. On the other hand, there is always things that is happening under the surface. They are usually less easy to point out. Beneath the surface, there are personalities. People behave, communicate, and get things done in different ways. After, there is emotions. To reach the best resolution we can, each party in a conflict should be true about their emotions by bringing empathy into the picture. Next, there is interests, needs, and desires. This is where each party should be curious. It is important to ask questions in order t o find out the needs and concerns behind people’s action. Also, self-perceptions and self-esteem. In the iceberg of conflict, there are hidden expectations. Here is when the conflicting parties should use their active listening skills to figure out the missing links. They should listen and try to understand the other party perspectives. Lastly, there is unresolved issues from the past. Keeping an open mind is critical in this stage.
