Benefits of reading newspapers Essay Example for Free

Benefits of reading newspapers Essay UIUC Physics 436 EM Fields Sources II Fall Semester, 2011 Supplemental Handout Prof. Steven Errede American Wire Gauge (AWG) Metric Gauge Wire Sizes AWG Wire Sizes (see table below) AWG: In the American Wire Gauge (AWG), diameters can be calculated by applying the formula: D(AWG) = 0.005 * 92 ((36-AWG)/39) inch. For the 00, 000, 0000 etc. gauges you use -1, -2, -3, which makes more sense mathematically than â€Å"double nought.† This means that in American Wire Gauge every 6 gauge decrease gives a doubling of the wire diameter, and every 3 gauge decrease doubles the wire cross sectional area – just like calculating dB’s in signal levels. Metric Wire Gauges (see table below) Metric Gauge: In the Metric Gauge scale, the gauge is 10 times the diameter in millimeters, thus a 50 gauge metric wire would be 5 mm in diameter. Note that in AWG the diameter goes up as the gauge goes down. Metric is the opposite. Probably because of this confusion, most of the time metric sized wire is specified in millimeters rather than metric gauges. Load Carrying Capacities (see table below) The following chart is a guideline of â€Å"ampacity†, or copper wire current-carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. As you might guess, the rated â€Å"ampacities† are just a rule of thumb. In careful engineering the insulation temperature limit, thickness, thermal conductivity, and air convection and temperature should all be taken into account. The Maximum Amps for Power Transmission uses the 700 circular mils per amp rule, which is very conservative. The Maximum Amps for Chassis Wiring is also a conservative rating, but is meant for wiring in air, and not in a bundle. For short lengths of wire, such as is used in battery packs, you should trade off the resistance and load with size, weight, and flexibility.  © Professor Steven Errede, Department of Physics, University of Illinois at Urbana-Champaign, Illinois 2005-2008.

Heart of Darkness in Relation to its Title Essays -- essays research p

The Parallel meaning of the novella with its title- Heart of Darkness The title, Heart of Darkness, aptly chosen, can be very strongly linked to the novel. IT can be used to describe Joseph Conrad’s views on civilization, the individual mind and the land into which he ventures. These sum up his opinions on the bourgeoise society, uncivilized society and the faults of human nature, linking them to the land under one common theme and thus establishing the title. ‘Heart of Darkness’ can most noticeably describe Marlow’s journey into the heart of the land. A dominant symbol in the novel is of the river- the snake- â€Å"But there was in it one river especially, a mighty big river, that you could see on the map, resembling an immense snake uncoiled with its head to the sea, its body at rest curving afar over a vast country, and its tail lost in the depths of a land† (71). This river brings him into what has become a ‘dark’ place- â€Å"It had ceased to be a blank space of delightful mystery- a white patch for a boy to dream gloriously over. It had become a place of darkness† (71). As in snakes and ladders, you start at the head and go towards the tail. This leads him into evil (snake symbolism), danger (uncoiled), and deeper towards Kurtz, whom the snake has swallowed towards the tail. As he travels along, just as the snake’s body grows thinner, so do the tolerance levels of those who thin k they are civilized. First Fresleven clubs a black village chief, then a brawl breaks out, and this progresses to all-out insanity, where cannibals, primitives, Inca-like natives and, eventually, Kurtz, reside, where he loses any control he had of his life, doing anything for more ivory, and realizes this in his dying moments. Marlow again mentions headin... ...ke hell break loose. Voyage into the land increases the themes of death and chaos. However, with the trek into the heart of the land, the other two concepts significantly grow- civilization becomes more and more edacious, and the dark heart of each individual is more likely to burst free. This may very well explain how when with his aunt, Marlow is so resisting that he states that the company is totally profit-oriented. By the time he has been at the station for a period of time and reads Kurtz’s book, he actually considers his views on the inferiority of the natives. Also note how the continent ‘got to’ Fresleven, causing him to go insane. The half-hidden, negative side in each concept becomes the ‘heart of darkness,’ both relating it to the title and a very unifying theme. Bibliography Conrad, Joseph. Heart of Darkeness. New York: Chelsea House, 1987.

The Waiting Girl

The image that I have chosen to research is The waiting Girl by Loretta Lux. The image was published in 2006 in Germany. The image is about time and timelessness, the girl and the cat are frozen in time waiting for eternity. The little girl is simply waiting for nothing it is like what ever gets thrown at her next will be her opportunity. The waiting girl is one of Loretta’s best works; it is also one of her most famous work. Stated by Loretta â€Å"I started with the idea of a girl sitting on the sofa waiting for nothing in particular and the cat came into the idea later. I love cats and I had to try and incorporate cats into my images for a long time but never worked but this time worked extremely well†. The image shows a little girl sitting on a chair and a cat laying next to her. This image shows the innocence of the little girl with her legs crossed, her hair in two buns, and her clothing so pail and vintage. You will not see many young girls dressed like this today. The chair is the first thing that is noticed in the image it is the colour red being bright and red the meaning of love, waiting for something to happen and for her life to carry on and a child’s life should. The colour’s used in this photograph are pail and as known now vintage colour’s. The girl, cat, wall and floor are all mostly in the same tones and blend in with each other this which then makes the chair center of attention and is the most appealing aspect to the eye. Above the lounge there is a bow, which also shows the innocence of the little girl and her childhood. The meaning of each colour relates back to this image: Red the colour of fire and blood, energy, danger, strength, power, passion, desire, and love. Beige the colour of warmth. Brown the colour of stability, reliability, approachability, natural and organic. White is the colour of purity. The texture of this image looks smooth but the lounge is rough and so is the floor, this gives the image an effect of time, meaning that the chair and floor have now changed over time we now have smooth floors e. g- carpet and tiles, and the lounges today are now soft and made out of soft fabrics and leather. The image does not represent a historical time although we could say it does, the vintage colours, the innocence of the little girl, the lounge which we do not see often at all these days. Though the look if the image is of a very heritage era. Size is a factor in the image the by the size of the lounge compared to the girl and the cat. The girl is of a very small proportion of the image where space overrides the image. The reason I chose this image is because it caught my eye and it had a impact on me, this image caught my emotions. I thought it would be a good image to talk about although there is not much detail on this image. The image is very simple and plain and shows the innocence of young girls growing up. It reminded me of when I was growing up and how different things were. It was all about playing and getting out hands dirty, but when compared to this image it is the complete opposite. It’s all about the sweet innocence of the young girl. The image that I chose I think is a good one, it can relate to many things in a childhood. Nearly every girl who sees this will feel the connection with the image some may feel exactly the same and others like my self may feel opposite. There were two ways of being brought up the classy/ elegant way or the casual way. Many of us girls today can relate to the casual way is it is now the 21st century. My overall response to this image is that I think that it was portrayed very well, without even reading about the image many people would understand the image and have a connection with it. I really like this photo and I find it very detailed once you look into the image and find out more about it and find out that there is more behind this image than we can see. I believe that every image has a story and has its own message behind it and to me I find that this message being sent out about this image is that time s the main factor in our daily lives. It’s what ever gets thrown at us many of us will take. I find this image a very appealing image and believe that behind every image there is a story, and this image does have a story and that is that life is based on time. Every artist looks at things completely different and have there own thoughts on there images but in most cases it is something that has related to their lives and in this case it is Loretta related this image to her upbringing and her love for cats. In conclusion, this image is fantastic I find it very appealing although it is very simple it does have a detailed background and is an eye catching image. I find that the colour’s work very well with the theme of innocence and time the natural colours and show the purity of the girl. Though when we compare these colour’s to todays colour’s they are very different we now use very bright colours and show the excitement in the child’s life. The image is worth all the attention that it receives and has more and more comments about it every day, each person has a different opinion but I find this very appealing and attractive.

The Appeal of Dystopian Novels for Teens

Teens are devouring the current popular literature of the dark, grim, and dismal: the dystopian novel. Bleak story lines about leaders who  terrorize citizens every year by making them watch teens fight to the death and governments who condone mandatory operations to remove emotion describe two of the popular dystopian novels that teens are reading.  But just what is  a dystopian novel and how long has it been around? And theres the bigger question: why is this type of novel so appealing to teens? Definition A dystopia is a  society that is broken down, unpleasant, or in an oppressed or terrorized state. Unlike a utopia, a perfect world, dystopias are grim, dark, and hopeless. They reveal society’s greatest fears. Totalitarian governments  rule and the needs and wants of individuals become subordinate to the state. In most dystopian novels,  a tyrannical government is trying to suppress and control its citizens by taking away their individuality, as in the classics 1984 and Brave New World.  Dystopian governments also ban activities that encourage individual thinking. The governments response to individual thinking in Ray Bradbury’s classic Fahrenheit 451? Burn the books! History Dystopian novels are not new to the reading public. Since the late 1890s, H.G. Wells, Ray Bradbury, and George Orwell have entertained audiences with their classics about Martians, book burnings, and Big Brother. Over the years, other dystopian books like Nancy Farmer’s The House of the Scorpion and Lois Lowry’s  Newbery-winning book The Giver have given younger characters a more central role in dystopian settings. Since 2000, dystopian novels for teens have retained the dismal, dark setting, but the nature of the characters has changed.  Characters are no longer passive and powerless citizens, but teens who are empowered, fearless, strong, and determined to find a way to survive and face their fears. Major characters have influential personalities that oppressive governments attempt to control but cannot. A recent example of this type of teen dystopian novel is the incredibly popular Hunger Games  series (Scholastic, 2008) where the central character is a sixteen-year-old girl named Katniss who is willing to take her sister’s place in the annual game where teens from 12 different districts must fight to the death.  Katniss commits a deliberate act of rebellion against the Capital that keeps readers on the edge of their seats. In the dystopian novel Delirium  (Simon and Schuster, 2011), the government teaches citizens that love is a dangerous disease that must be eradicated. By age 18, everyone  must undergo a mandatory operation to remove the ability to feel  love. Lena, who is looking forward to the operation and fears love, meets a boy and together they flee the government and find the truth. In yet another favorite dystopian novel called Divergent (Katherine Tegen Books, 2011), teens must unite themselves with factions based on virtues, but when the main character is told she’s divergent, she becomes a threat to the government and must keep secrets in order to protect her loved ones from harm. Teen Appeal So what do teens find so appealing about dystopian novels? Teens in dystopian novels get to perform ultimate acts of rebellion against authority, and that’s appealing. Conquering a dismal future is empowering, especially when  the teens have to rely on themselves without having to answer to parents, teachers, or other authoritarian figures. Teen readers can certainly relate to those feelings. Today’s teen dystopian novels contain teen characters who exhibit strength, courage, and conviction. Although death, war, and violence exist, a more positive and hopeful message about the future is being sent by teens who are facing future fears and conquering them.
