How does Dolphus Raymond in To Kill a Mockingbird overcome prejudice ?

Dolphus Raymond is a landowner who has mixed-race children. This is not only a socially backward lifestyle for the time period, but people might not do business with such a man if they knew he was doing it on purpose. People might also shun him or his children in other ways; so, Raymond's way of battling this is to act as if he were drunk all of the time. The reasoning behind this is if people in Maycomb believe that he is a chronic drunk, then they will believe that his lifestyle is not necessarily by choice, but because of his predicament. Thus, he acts the part of a drunk whenever he is in town. Raymond explains his reasoning to Scout and Dill as follows:

"I try to give 'em a reason, you see. It helps folks if they can latch onto a reason. When I come to town, which is seldom, if i weave a little and drink out of this sack, folks can say Dolphus Raymond's in the clutches of whiskey--that's why he lives the way he does . . . Secretly, Miss Finch, I'm not much of a drinker, but you see they could never, never understand that I live like I do because that's the way I want to live" (200).

Raymond just wants to live his life in peace, without drama, and without drawing too much attention from Maycomb's society. Therefore, Dolphus Raymond overcomes prejudice by acting like a drunk and so he doesn't have to deal with it by answering to anyone. 

What is the activation energy for the hydrolysis of methyl formate?

The uncatalyzed reaction has an activation energy estimated at 5.44 kJ/mol, but this is a largely meaningless figure for practical purposes because when we manufacture formic acid we always catalyze the reaction. In fact, the reaction autocatalyzes--once you get enough formic acid in the solution, the formic acid acts as a catalyst and activation energy to make more of it decreases.

In practice, there are a variety of reaction procedures used which often involve different catalysts, so I can't give you a precise figure for their activation energies.

What I can tell you is that all the standard methods of producing formic acid involve autocatalyzed hydrolysis of methyl formate at temperatures between 80 and 140 °C and pressures between 3 and 18 bar.

How are characters' inner conflicts intensified by the imagery of light and darkness in Macbeth?

In Macbeth, there are many instances of the imagery of light and darkness. Light symbolizes clarity, goodness, and incorruptibility. Darkness, however, embodies impurity, evil, and corruption. 

Light and darkness are both employed to intensify the inner conflict of the major characters or the atmosphere in the country. I will list a few examples below.

1. When King Duncan declares Malcolm to be his successor, he speaks about the honor of other warriors in terms of light:

Malcolm, whom we name hereafter
The Prince of Cumberland; which honour must
Not unaccompanied invest him only,
But signs of nobleness, like stars, shall shine
On all deservers.

Duncan states that all those who have displayed valor, honesty and loyalty will be rewarded. Light is seen as good. Therefore, Duncan can be seen as a character standing up for true values. 

2. Darkness, unlike light, symbolizes evil. When Macbeth begins to succumb to his ambitions, he begins to accept darkness:

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...

His "black and deep" desires are evil and sinful because he wants to kill his relative and king in order to take the throne. His conscience attempts to warn him against these perilous desires, but Macbeth, guided by his ambition, pressured by his wife, and encouraged by the witches' prophecies, decides to embrace evil.

3. When Macbeth commits murder, we notice strange occurrences in nature. Disorder begins to take control of Scotland:

By the clock, 'tis day,
And yet dark night strangles the travelling lamp.

This disorder is shown through the image of darkness. 

4. In Act V, Scene 1, we see the perilous force of darkness and its effect on others. Lady Macbeth, who once summoned darkness, now demands light:

She has light by her
continually; 'tis her command.

Having realized darkness makes her fragile, Lady Macbeth no longer wants it. She realizes murdering Duncan is a bad idea, and continues to be haunted by it. Unfortunately, her realization is too late, and she soon succumbs to her death.

How many bones are in the face?

There are fourteen bones in the human face, including the lacrimal bones, the zygomatic bones, the vomer, the nasal bones, the inferior nasal conchae, the mandible, the maxillae, and the palatine bones. Several of these bones exist in pairs, like the zygomatic bones of our cheeks. 

The bones of the face offer protection for our sense organs as well as our brain. The maxillae and mandible are also responsible for breaking up foods through chewing.

When we look at a skull, it may not be apparent that there are so many bones in the face. It may even seem to be just one big piece of bone! But if you look closely, you may be able to identify the "sutures" where the bones of the face and cranium have fused together.

If you had unlimited money, what would Quince's costume look like in Act 1, scene 2?

Peter Quince is one of the "rude mechanicals" in A Midsummer Night's Dream, one of the craftspeople who seek to put on an impressive, tragic play for Theseus' marriage to Hippolyta. Quince is the author of the play and many scholars see him as a comic representation of Shakespeare himself; both wrote and were happy to take parts in their own plays, and both had backgrounds as craftsmen. Because of this, I think it would be fun to give a nod to Shakespeare in costuming Quince, perhaps by giving him similar facial hair to Shakespeare's famous portrait, or his receding hairline. You could even have him carry around a quill to write with and scribble furiously throughout the scenes he's in.

Looking at Quince's costume in a broader sense, his overall look depends on the setting of the play. If you stage it traditionally, in ancient Greece, Quince would likely wear a short robe in a bright color, with a rope to tie it at the waist and simple sandals. The play is so famous, though, that it could be staged in any time or place. In a modern-day production, Quince might wear a flannel shirt and overalls and sit in a Hollywood director-style chair. The key, I think, is to make sure that his costume portrays his modest origins (he is a working guy, after all), while still suggesting his plans for glory through the arts.

In To Kill a Mockingbird, what is the testimony of Sheriff Heck Tate about?

In chapter 17 of To Kill a Mockingbird, Sheriff Heck Tate is called as the first witness for the prosecution in the Tom Robinson trial. The sheriff is a witness to the night in question after the alleged crime was committed. This means that he only sees the aftermath of whatever happened, and is not a primary witness to any real crime. Thus, Sheriff Tate's testimony revolves around Bob Ewell fetching him on the night of November 21st, and claiming that a black man had raped his daughter. Like a good officer of the law, Sheriff Tate goes out to the Ewells' home and finds Mayella Ewell on the floor. He notices that she is badly beaten up, so he picks her up, washes her face and asks her who beat her up. She claims that Tom Robinson did it.

Then Atticus Finch gets a chance to cross-examine the sheriff and the first question he asks is if the sheriff called a doctor. Sheriff Tate says he didn't call a doctor. Without a doctor's diagnosis, the only thing Atticus can do is take the sheriff's eye-witness account of the wounds on Mayella's body. After much discussion, it is decided that she was mostly hurt on the right side of her body. Specifically, her right eye was bruised the worst. The sheriff's testimony that Mayella was beaten on the right side of her body is critical to the defense because that means that a left-handed man must have hurt her. Atticus later proves that Tom Robinson couldn't have beaten or raped Mayella because Bob Ewell is left-handed and Tom Robinson's left arm is disabled.

In The Loved One by Evelyn Waugh, how does Dennis Barlow demonstrate the theme that death is artificial in America ?

The Loved One by Evelyn Waugh is a satirical novel that targets what Waugh considers the inanity and superficiality of American life. The targets of his satire include Hollywood, the mortuary industry, and journalism. In each case, he shows that under a facade of moral seriousness lies corruption, acquisitiveness, or stupidity. 

The most biting satire in the book is reserved for the operation of The Happier Hunting Ground, a pet cemetery that is seen through the eyes of Dennis Barlow, a cynical Englishman, whose poetry is just as much a facade as the ornate funerals given to the pampered pets of the Hollywood elite. 

The artificial nature of death is shown in the way corpses are made to look almost alive through the use of cosmetics, sanitizing the experience of death. Death is also sugar-coated through sentimentality and ritual. By blending pet and human deaths and refracting the experience of human mortuary services through animal ones which hold up a mirror to them, Waugh shows that death has been sugar-coated and made almost unreal and overly pretty in the American tradition. As a devout Catholic himself, Waugh is implicitly suggesting that the saccharine cliches of commercialized funerary homes have replaced a more profound religious understanding of death.

The most biting critique occurs when Dennis arranges for Joyboy to receive the following annual message:

Your little Aimee is wagging her tail in heaven tonight, thinking of you.

This sort of anodyne reminder of the anniversary of a death stands in opposition to the profound ritual of the All Souls' liturgy commemorating the faithful departed.
