Why must left ventricular pressure be greater than aortic pressure during ventricular ejection?Anatomy-Heart

In the healthy myocardium left ventricular pressure is
higher than aortic pressure because the left ventricle of the heart propels blood into
the aorta and aortic arch which then pushes the blood into the brachiocephalic, left
common carotid, and left subclavian.  However, in different types of cardiac disease
this is not the case. A good example of this is left ventricular hypertrophy. With LVH
the inherent pressure of the left ventricle can be decreased due to the hypertrophic
chamber. All hypertrophied muscles are not necessarily a positive situation. LVH
commonly causes backflow of blood and myocardial and pulmonic congestion which leads to
a multitude of problems. This would adversely affect the cardiac output (lower it) and
disrupt the normal filling times of the other chambers.

Please explain why Volpone is a comedy of humours.

The word “humours” when applied to this play refers to a
concept that was popular during Ben Jonson’s day. Humors were temperaments or people’s
personalities. The belief was that these personalities flowed through people. The word
“humour” comes from a Latin word, “humor”, which means liquid. In Medieval times, there
was a medical theory that held that the human body was a balance of four humors or
liquids: blood, phelgm, yellow bile (choler) and black bile (melancholy). If these
liquids were balanced in one’s body, then the person was healthy. If they were out of
balance, however, then the person was messed up.

In drama
and literature, this theory translated into four main personality types: melancholic,
sanguine, choleric and phelgmatic. Some believed that all people were primarily one of
these types of personalities, although they could also have elements of the other
three.

A comedy of humors refers to a type of drama that
focused on characters, each character representing a type of personality. Ben Jonson was
one of the main writers of this genre and you can see it in
Volpone. The characters in Volpone are
stereotypes. They represent a character type rather than a flesh-and-blood character
whose mind we can get into when we read the play. In a comedy of humors, the characters
are the most important focus, so Volpone fits this criterion. All
of the characters are imbalanced as well, so their “humors” are out of sync and they
thus act in comical ways. There are some characters in this play that have physical
abnormalities (Nano, Castrone & Androgyno) and yet they are not as out of
balance as the ones who are mentally imbalanced (Volpone, Mosca, Voltore, Corvino,
Corbaccio, etc.)

When does Percy die?

Percy-Boyd Staunton (later shortened to Boy Staunton) does
not die until the third book of the series World of Wonders.  He is
killed, or is suggested into killing himself, by Magnus Eisengrim.  Magnus Eisengrim was
once a little boy in the same town as Percy-Boyd and Dunny, and it was his mother, Mary
Dempster, whose madness was caused by Percy-Boyd all those years
ago.

When Dunny and Percy-Boyd were coming home from
sledding, Percy threw a snowball (later revealed to have a rock inside it) at Dunny. 
Dunny ducked, and the snowball hit the pregnant Mary Dempster.  She had her premature
baby that night, and was never right in the head again.  Eventually she sunk into
complete madness, and was cared for most of her adult life by Dunny.  Percy never took
responsibility for this action, and it is not entirely clear that he even really
understood his culpability.

Magnus (little Paul Dempster,
then) ran away from home and joined the travelling circus, because of his mother's
disgrace and madness and his father's controlling ways.  There he was horribly treated
and lead a life which he blamed on Percy (he didn't fully understand whose fault it was
until the night he met Boy Staunton as an adult).  Magnus says that he only suggested
that Boy Staunton kill himself.  Magnus was such a consummate magician and hypnotist
that he may have been able to do such a thing, but it is also possible that Magnus
somehow made Boy drive his car into the water.  It is not entirely clear at the end of
the novel what happened, but it is clear that Magnus is in some way responsible for
Boy's death -- just not how much!

What is Hansberry's view on the American Dream and how does the ending of A Raisin in the Sun give evidence towards her vision?

Hansberry has a fairly positive and optimistic view of the
American Dream.  She rightly concedes that for people of color, specifically African-
Americans, there are some challenging factors in terms of race and the social order's
perception of it that make this pursuit challenging.  She also accurately depicts that
economic class plays a large role in how one can appropriate their own version of the
American Dream.  Yet, she rightly, in my mind, does not lock individuals in these
stratifications from their pursuit of the American Dream.  Hansberry's view of the Dream
seems to be that it is difficult and requires a sense of courage with commitment in
order to pursue it.  She also suggests that there are many distractions on this voyage
of which one must be vigilant.  In this sense, those who are in pursuit of the American
Dream are no different than Homeric characters who must battle through much in way of
adversity on their quest and even then, success is not guaranteed.  For each Odysseus,
there are many more Hectors.  For each Walter, there might be more Bobos or nosy
neighbors who envy others.  In the end, Hansberry believes that the pursuit of the dream
is worth it, in that it allows our own plants to be stronger and better.  She is mindful
of Hughes' poem, but offers a vision that might diverge from its last
line.

Could you please justify the title of the story " A Fishy Story" by Jerome Klapka Jerome? Does the word "Fishy" have a pun?

"A Fishy Story" is a story about the narrator and his
friend, staying in an inn. In the lobby, they find a trout placed in a glass case over
the wardrobe. They find many people, claiming that they had caught the
trout. It filled the two with laughter, and a bit of suspense as well.
They tried to get hold of the trout, but fumble, and drop it down. It broke into several
pieces. They found it absurd how a stuffed trout could break; then they realise that it
was made up of Plaster of Paris.

There is a pun intended on
the word "Fishy". Firstly, it refers to the FISH itself. At
the same time, it refers to the aroma of curiosity and
suspense created.

What is the term of office for federal judges?

In the United States, the term of office for federal
judges is life during "good behavior."  In other words, a federal judge, once approved
by the Senate, can stay on the bench until he or she dies or decides to retire.  The
only exception to this rule is that judges can be impeached for "high crimes or
misdemeanors."  This is very, very rare.

The reasoning
behind this term is that judges need life terms in order to be independent.  If they
could be easily removed by Congress or the President, they would tend to rule in ways
that those people wanted.  This would mean that they would not truly be a check/balance
the way they are supposed to be.

What causes colors to be emitted when ions are put into a flame?Please write a paragraph answer and include these words: electron, electron...

Ions are atoms which have given electrons to, or gained
electrons from, atoms of other elements. The ions thus formed have a more stable
electron configuration. When a compound is heated, the ions absorb energy. This changes
their electron configuration and it reaches an excited state. In an effort to return to
the original electron state, which is also called ground state, the ions release the
energy that they have absorbed.

The release of energy is
accompanied by the emission of a photon. Now the color of light is determined by the
wavelength of the photon and the relation between the energy of a photon and its
wavelength is E = c*h/ L where E is the energy, c is the speed of light, h is the
Planck's constant and L is the wavelength.

The energy
absorbed by ions is dependent on the energy level of the ground electron configuration
and the energy levels of the excited states. As this varies for different metallic ions,
so does the color that is emitted by them when they are heated.
