All About Plastics

All About Plastics Every day, people use plastics in various applications. Over the last 50 to 60 years, the uses for plastic have expanded to infiltrate virtually every aspect of life. Because of how versatile the material is, and how affordable it can be, it has taken the place of other products including wood and metals. The properties of the various types of plastics make it beneficial for manufacturers to use. Consumers like it because it is easy to use, lightweight and easy to maintains. Types of Plastics Overall, there are about 45 unique types of plastics and each type has dozens of different variations. Manufacturers can change the physical structure just slightly to benefit the application for which they are using it. When manufacturers change or modify things like the molecular weight distribution, the density or the melt indices, they alter the effectiveness and create plastics with many specific properties - and therefore many different uses. Two Plastic Categories There are two main types of plastics, thermoset plastics and thermoplastics. Breaking these down further, you can see the everyday uses of each type. With thermoset plastics, the plastic will hold its shape long term once it has cooled to room temperature and hardened thoroughly. This type of plastic cannot return to its original form - it cannot be melted down into its original form. Epoxy resins and polyurethanes are some examples of this type of thermosetting plastic. It is commonly used in tires, auto parts, and composites. The second category is thermoplastics. Here, you have more flexibility and versatility. Because it will return to its original form when heated, these plastics are commonly used in various applications. They can be made into films, fibers, and other forms. Specific Types of Plastics Below are some of the specific types of plastics and how they are in use today. Consider their chemical properties and benefits, too: PET or Polyethylene terephthalate - This plastic is ideal for food storage and water bottles. It is commonly used for things like storage bags, too. It does not leach into the food, but is sturdy and can be drawn into fibers or films. PVC or Polyvinyl Chloride - It is brittle but stabilizers are added to it. This makes it a softer plastic thats easy to mold into various shapes. It is commonly used in plumbing applications because of its durability. Polystyrene - Commonly known as Styrofoam, it is one of the less ideal options today for environmental reasons. However, it is very lightweight, easy to mold and it works as an insulator. That is why it is heavily used in furniture, cabinetry, glasses and other impact-resistant surfaces. It is also commonly added with a blowing agent to create foam insulation. Polyvinylidine Chloride (PVC) - Commonly known as Saran, this plastic is used in wraps to cover food. It is impermeable to odors from food and can be drawn into various films. Polytetrafluoroethylene - A growing popular choice is this plastic also known as Teflon. First manufactured by DuPont in 1938, it is a heat-resistant form of plastic. It is very stable and strong and is unlikely to be damaged by chemicals. Moreover, it creates a surface that is almost frictionless. This is why it is used in various cookware (nothing sticks to it) and in tubing,  plumbing tapes and in waterproof coating products. Polypropylene - Commonly called just PP, this plastic has various forms. However, it has uses in many applications including tubes, car trims, and bags. Polyethylene - Also known as HDPE or LDPE, it is one of the most common forms of plastics. New formations of it make it possible for this plastic to be flat. Its initial uses were for electrical wires but it is now found in many disposable products, including gloves and garbage bags. It is also used in other film applications such as wraps, as well as in bottles. The use of plastics every day is more commonplace than many might think. By making small changes to these chemicals, new and versatile solutions are obtained.

Does nationalism need to be based on ethnic myths of descent Essay

Does nationalism need to be based on ethnic myths of descent - Essay Example Historical process of nationalism will indicate that the nationalism as a process started in the Europe during 19th Century.(Anthony,1993). On a larger scale it attempts to provide the criterion for the creation or ownership of the legitimacy of power over a State by people having certain characteristics. This doctrine therefore indicates that the societies in the world are divided based on the nations each having their own distinctive characteristics and as such the only form of legitimate government can only arise if national self government is imposed over the State. Thus nationalism is necessarily considered as a political ideology which advocates the case of controlling the State by a nation. Since State derives the legitimate obediences it is therefore argued that to wield the control over the population and achieve political legitimacy it is critical that the power must be relocated to a nation to govern the State. (Featherstone,1990) French Revolution is considered as the starting point from where the emergence of strong nationalistic sentiments started to emerge and dominate the political scene of the countries. At this point, it was clearly established that the only sovereign is the nation with the sole power of making laws to its citizens therefore the individuals must show the loyalty to the nation. French Revolution is critical in the sense that it was the turning point to break away the barriers that separated the various regions of the country and united them as a one nation based on single language and culture.

Richard Wilbur Boy at the window Essay Example for Free

Richard Wilbur Boy at the window Essay When one is considered naive, it has been thought to determine one as â€Å"having or showing a lack of experience, judgment, or information; credulous† (www. dictionary. com). In Richard Wilburs’ poem, Boy at the Window, Wilbur uses simple form language to paint the image of the boy staring out the window at the snowman. In the beginning of the poem, Wilbur reveals two characters, one a snowman and the other a young boy. Both characters in the poem seem to have a connection to each other, and may even consider themselves, friends. Perhaps the boy may have helped to build the snowman. One day during an incoming storm, the boy peers outside the window and appears to be frightened for the snowman because the snowman has no shelter from the storm â€Å"In dusk and cold is more than he can bear† (Clugston, 2010). The boy fears for the snowman’s life because the boy realizes the rain will melt the snowman away. However the snowman does not want to come inside the warm house with the boy for fear he will melt and die. In this case who is naive, the boy or the snowman? Beginning from the perspective of the boy staring out the window, it is obvious the boy feels helpless. The boy realizes that a storm is coming, â€Å"A night of gnashing and enormous moan†, (Clugston, 2010) which will eventually wash away the snowman. When the boy feels the snowman is going to die the boys emotions turns to one of hurt. The young boy does not understand that the snowman needs the cold to survive, even if it means death when it rains. The tone of the poem indicated that perhaps the boy feared what the outside world held for the snowman, and the storm intensified that. In one world, the inside, the boy felt â€Å"Such warmth, such light, such love, and so much fear† (Clugston, 2010). He wanted the snowman to experience the same warmth as he did because the boy took comfort in his surroundings and identified what made him feel safe in his eyes. On the other hand, perhaps the snowman felt sympathy for the young boy. From the outside, the snowman seems to understand how the boy is feeling. So the snowman sheds a tear for the boy because he understands the boy cares a lot about him, â€Å"He melts enough to drop from one soft eye A trickle of the purest rain, a tear†, (Clugston, 2010). Because the snowman does not have a fear of the rain, the snowman does not seem to understand that the storm will cause him to melt away, as he is quite comfortable with being outside in the cold. While the snowman looks quite comfortable outside, the snowman may not portray that feeling to the young boy looking at the snowman from his home. Overall, the theme of the play speaks volumes about being naive and misinterpretation of viewing another persons’ life and how they choose to live it. This point of view that Wilbur tried to relay to the reader allowed me to focus more so on the snowman and how he wanted to live than the boy. As human beings, one always wants to change what they believe to be wrong in society without asking the person(s) if they want the change. One should never determine how a person’s life should be lived based off of how they are living there own life. But this fact that we are not aware of certain systematically proceeding misinterpretations does not only shape the image of personality, as constituted in the naive and experience of everyday life, but also influences scientific thought, (Ichheiser, 1943). Both are considered to be inexperienced about the fundamentals of life and how they both lived. The boy took comfort in believing that if the snowman were rescued by bringing the snowman in the house, the snowman would be saved. The snowman believed that by staying outside, no harm would come to him and he was not alone or afraid of the incoming weather, because he had nothing to fear of living outside alone and in the dark. The boy and the snowman lived two diverse lives, one that could never be meshed together because of the scientific fact that one character lived a cold life and the other character lived a life in which there was warmth.

Custom Written Term Papers: Othello’s Involved Imagery :: Othello essays

Othello’s Involved Imagery  Ã‚        Ã‚  Ã‚   The intricate imagery peppering the language of the characters in Shakespeare’s drama Othello is deserving of our detailed consideration in this paper. It has significant meaning, and nearly expresses a life of its own.    The play’s imagery is oftentimes reflective of the fortunes of the protagonist. As the Moor’s status declines, the quality of the imagery in the play declines. In The Riverside Shakespeare Frank Kermode explains the relationship between imagery and Othello’s jealousy:    It is very important to see that Othello’s self-estimate – â€Å"one not easily jealious, but, being wrought, / Perplexed in the extreme† (V.ii.345-46) – is, as Bradley says, â€Å"perfectly just,† and perfectly consistent with the release of unsuspected grossness of language and imagery under the shock of discovering infidelity in the loved one. The peculiar pain of sexual jealousy is deeply involved with the excremental aspect of the sexual organs, and the emotion in betrayal in a supremely intimate trust is involved with agonizing associations of filth and animality. (1200)    A surprising, zoo-like variety of animal injury occur throughout the play. Kenneth Muir, in the Introduction to William Shakespeare: Othello,   explains the conversion of Othello through his increased use of animal imagery:    Those who have written on the imagery of the play have shown how the hold Iago has over Othello is illustrated by the language Shakespeare puts into their mouths. Both characters use a great deal of animal imagery, and it is interesting to note its distribution. Iago’s occurs mostly in the first three Acts of the play: he mentions, for example, ass, daws, flies, ram, jennet, guinea-hen, baboon, wild-cat, snipe, goats, monkeys, monster and wolves. Othello, on the other hand, who makes no use of animal imagery in the first two Acts of the play, catches the trick from Iago in Acts III and IV. The fondness of both characters for mentioning repulsive animals and insects is one way by which Shakespeare shows the corruption of the Moor’s mind by his subordinate. (21-22)    Just how strong a force is the imagery in this drama? Is it more powerful than the chorus in ancient Greek tragedy? H. S. Wilson in his book of literary criticism, On the Design of Shakespearean Tragedy, discusses the influence of the imagery of the play:    It has indeed been suggested that the logic of events in the play and of Othello’s relation to them implies Othello’s damnation, and that the implication is pressed home with particular power in the imagery.

Drug Testing Welfare Recipients Essay

Many people are constantly discussing the issue of welfare recipients abusing the system and spending their money on drugs while receiving government assistance. This issue has brought forward a possible solution of states passing legislation that will require welfare applicants to submit to a drug test before receiving any sort of government assistance. Drug testing welfare applicants before allowing them to receive assistance is a positive idea because most employers require drug tests to be taken by applicants pre-employment. This will help make sure that the government funding is being put toward the family and the needs of the household, and also because in the future it will benefit the children growing up in the home. All welfare applicants should be drug tested prior to receiving funds. Most employers today require pre-employment drug screens and some employers also drug test their employees randomly throughout their time of employment. They do this to ensure that they are hiring a responsible employee that will not show up to their place of employment while under the influence of illegal substances. As everyone knows, illegal substances that employees test for are typically mind altering medications that prevent people from functioning normally and doing their job to their full potential. Working while under the influence of illegal drugs also poses a safety risk to the employee and surrounding employees. If to earn an income at most jobs people are required to pass a pre-employment drug screen, there is no reason that to earn an income provided by the state should be any different. Some employers also require their employees to submit to random drug tests while employed with their company or business so that no one can â€Å"cheat the system. † This helps employers make sure that their employees are drug free at all times. When a welfare applicant is granted assistance, the state assumes that all of their means of income are being used to buy items that are needed by the family and by the household. However that is not always the case. In some welfare cases the recipients are abusing drugs. By drug testing the recipients before granting their request for assistance and then randomly drug testing them throughout the time frame that assistance is required, this will significantly lower the amount of recipients that abuse drugs. Arizona representative and member of the Committee on Health and Human services, Kimberly Yee states that, â€Å"Arizona established a program in 2009 to test welfare recipients for drug abuse when there’s a reasonable suspicion of drug use. This program confronts addicts with their drug abuse problems so they may quickly receive treatment and become productive members of society again. † If welfare recipients confront their problem and become productive members of society it will ensure that any possible income will be going toward things that the family and children need such as food and clothing. Children who are raised by sober parents start off with a chance at a brighter future than children who are raised under the care of a drug addict. Parents who work regular jobs and are required to pass a pre-employment drug screen are able to provide more for their children. Instead of spending their money on drugs or alcohol, they use it to buy items for their children. Sober parents have more money to buy food to make sure that their children are well nourished. Sober parents also have more money to buy items like books, coloring books, crayons, markers, or arts and crafts supplies which will all be assets to a child’s learning and development. Children of sober parents are more likely to be able to join groups or teams in schools also which will help them socialize. All in all, growing up with sober parents benefits children and can seriously affect their future positively. Growing up with parents who use illegal drugs could create a pattern throughout their children, and they could end up using drugs as well when they grow up. The Office on Child Abuse and Neglect, Children’s Bureau, ICF International states that, â€Å"Children who experience either prenatal or postnatal drug exposure are at risk for a range of emotional, academic, and developmental problems. For example, they are more likely to: experience symptoms of depression and anxiety, suffer from psychiatric disorders, exhibit behavior problems, score lower on school achievement tests, and demonstrate difficulties in school† (â€Å"Protecting Children†). If we can lessen the amount of children that are forced to grow up with â€Å"high† parents, we can brighten the future for everybody. Drug testing welfare applicants before allowing them to receive government assistance will be beneficial because most employers require drug tests to be taken by applicants pre-employment, it will help make sure that the government funding is being put toward the needs of the household, and also because in the future it will benefit the children growing up in the home. If to go out into the public and get a job you are required to pass a pre-employment drug screen, then there is no reason that to earn income from the government should be treated any differently. Drug testing welfare recipients will increase the number of children raised by sober parents instead of parents that are under the influence of illegal substances. States passing legislation to require welfare applicants to submit to a drug test before they are granted assistance will only benefit people positively.
