Thermoforming essays

Thermoforming essays Thermoforming is one of many manufacturing processes that converts plastic resin into usable everyday products. Thermoforming is greatly relied on in today's society because of the tremendous need for high volume plastic products. Thermoforming is considered to be one of the most cost-effective processes in plastics manufacturing. Thermoforming is considerably economical because of the low molding costs and fast molding cycles. Speed and cost efficiency are the highlighted qualities that thermoforming offers which lead the way for the process becoming so important in industry today. The basic concept of thermoforming is quite simple. A premanufactored thermoplastic sheet is heated until it becomes soft and pliable. It is then forced against the contours of a mold until it cools to its original state. Once it has cooled it is removed from the mold while still obtaining the shape of the mold. Usually the product is then trimmed to produce the finished product. The operation seems simple and straight foreword but there are many different applications associated with the process. Thermoforming is a broad term; there are many different types of thermoforming processes. These processes all have similar traits but they do differ in certain aspects of the overall process. Trapped Sheet Forming is a specialized type of thermoforming. In trapped sheet forming a hot blow plate is used in both the heating and forming process. A plastic sheet is positioned between the hot blow plate and the female mold cavity. Air forced through the plate and pressure from the female mold combine to thrust the sheet onto the hot plate. The sheet is then heated and forced into the female mold by the use of air pressure. One advantage to trapped sheet forming that is such a simplified process that many products can be produced from this method. Also the process uses contact heating, which is easily used and is not subject t ...

A Personal Opinion on Barack Obama Being the Best President in American History

A Personal Opinion on Barack Obama Being the Best President in American History When I was in first grade, Barack Obama was elected as the 44th President of the United States. The week leading up to his Inauguration, my parents were unusually excited. As my mom was brushing my hair, I remember asking â€Å"What’s the big deal?†. My mother’s response was â€Å"We are witnessing history†. Not only was he an inspiration, but to me, he was the greatest President in American History. To start with the obvious, President Obama was the first black president in American History. At the time my fellow classmates didn’t realize the scale of this movement, but looking back at our countrys history, this was a big move. Even though it seems like a long time ago, the Civil Rights Movement was less than 50 years ago. This country was built on slave labor. Flash Forward to his presidency, and out of 80 policy positions requiring Senate confirmation, President Obama appointed more than women and minorities in 53.5%, compared with 25.6 percent during George W. Bush’s presidency. (Eilperin 5) Frankly, I’m surprised most people forget that it was during President Obama’s Presidency that the mastermind behind 9/11, Osama Bin Laden, was captured and killed. That reason alone should move him to the top of our greatest presidents list. 9/11 was the single worst terrorist attack in American history, and changed the politics and policies of our nation for years to come. On June 27th, 2015, America woke up to the news that same-sex marriage was legalized. This stopped 14 states where it was illegal to marry the same sex from enforcing their discriminatory laws on the LGBT+ community. In a press conference, President Obama’s response to the ruling was something that stuck with me for the next two years. â€Å"When all Americans are treated as equal, we are all more free† (BBC 6). These words should apply everywhere in our country, because our diversity is what truly makes America great. Though it was controversial, President Obama attempted to create nationwide healthcare for America, under the Affordable Care Act. It was opposed because it created too many costs on business, with many describing it as a job killer. However, studies show jobs in the healthcare sector rose by 9%. (BBC 8) No matter the cost, people deserve healthcare. Even though it was a flawed system, the fact that he attempted to create nationwide healthcare was a big step in the right direction. No person is perfect, including our president. You can have the best intentions and still making the wrong decision, but the real test is what you do to correct yourself. Admitting you’ve made a mistake is something to respect in any person, especially a president. Future Presidents should admire President Obama not only for this, but for keeping a calm and level head when faced with discrimination. When President Obama was elected, he was threatened to be hung, people burned effigies of him, and tried to convince the country he wasn’t a true legal citizen. (Dionne 1) It may be the President’s job to act calm and serious, but as a human being, keeping patience during this is extremely difficult. President Barack Obama, the first black president, led the way for progressive ideas. He took down the mastermind behind 9/11, and created nationwide healthcare. Not only this, but President Obama led the way for other minorities to take places in office. Soon, maybe we’ll have our first Hispanic, or even Muslim President! But for now I, along with the rest of America, will look back fondly and with respect to his presidency.

Rebuilding the Balkans Essay Example | Topics and Well Written Essays - 3000 words

Rebuilding the Balkans - Essay Example Taking a look at the brief history of international intervention in the Balkan region will elucidate some of the reasons for intervention, the aims of those who intervene and the consequences of their actions, which often differed from their aspirations. The main issue discussed in this article is the contemporary remarkable continuities in the approach of the western world towards the Balkan states, with multilateral intervention largely being driven by a desire to contain crisis and maintain the status quo in a region perceived as lying on the periphery of Europe. With the exception of Greece, it was only until the mid-1990s when the policy was prefigured earlier, have there been signs that such approach might be replaced by a qualitatively different one based on contractual engagement and a possibility of eventual integration into the European mainstream. Contrastingly, the meaning of integration for the Balkan space remains vague. Within the Stability Pact for South Eastern Europe and the Stabilization and Association Process there are suggestions that it could eventually lead to EU accession and, certainly, this is the dream of many within the region. However, with the EU already facing the challenge of an unprecedented enlargement into Central Europe and the Baltic, the likelihood of this occurring within the short or even the medium term remains doubtful. Alternatives to membership have been canvassed, and European Commission President, Romano Prodi, has even floated the idea of some form of 'virtual membership' for the states of the region, but, if this is the case, will integration itself be anything less than 'virtual' (Siani-Davies 2003). International Intervention in the Balkans The wars in the western Balkans could be considered a laboratory for post-Cold War intervention. There have been five conflicts over the last decade: Slovenia 1991; Croatia 1991-1992; Bosnia-Hercegovina 1992-1995; Kosovo 1999; and Macedonia 2001. As a consequence of global media attention and civil society pressure, outside powers have been learning to adapt the forms of intervention to an interconnected globalised world. Broadly speaking, it is possible to distinguish between two types of security philosophy that have guided interventions in the Balkans. One has been the traditional geo-political approach, in which security is understood as the defence of territory. The geo-political approach tends to be top-down, using diplomatic, economic and military pressure to influence political leaders and warring parties. The other approach is cosmopolitan in which security is understood as the defence of individual human beings. This approach is bottom-up; the emphasis is on respect for human rights, support for civil society, economic assistance and regional cooperation. Top-down approaches, of course, remain important, but they are shaped by bottom-up priorities. In the context of globalization, geo-political approaches to security have perverse effects - they lead to fragmentation and instability. Indeed, it is the attachment to territory and borders that explains the disintegrative process in former Yugoslavia. By and large, the United States has tended to pursue geo-political

(Microeconomics) - Assignment Example It also assists government to take advantages of expenses associated with clerical works. Moreover, government can effectively avert unhealthy market competitions. 3. Utilities such as water, gas, and electricity are some of the examples of natural monopolies. Government must set price ceilings in national monopoly markets since products and services under this category are necessities that people may buy at any higher prices. 4. In both the cases, profit must be zero in long run equilibrium. Firms are affected by changes in demand conditions under both cases. A major similarity between monopolistic competition and perfect competition is that competition in pursuit of profit encourages efficient resource movements. 5. In the case of a monopolistically competitive firm, demand will increase and average cost will increase in the long run. Under such circumstance, monopolistically competitive firms end up making zero economic profits. 6. A monopolistically competitive firm chooses the level of output where marginal cost equals marginal revenue. The firm maximizes its profits so as to achieve this situation; and it is called short run equilibrium of the firm. This condition adds to the price fixation flexibility of the firm. Moreover, it enables the firm to rapidly adjust with unexpected market fluctuations. b. Availability of different varieties of breakfast cereals gives an opportunity for consumers to distinguish them on the ground of their quality and price. It also gives consumers chance to buy their most preferred

The Red Channels Essay -- Politics Communism Communist

â€Å" I am a man of a thousand faces, all of them blacklisted.† -Zero Mostel, comedian â€Å"featured† in Red Channels The Red Channels: The Illegitimacy of America’s Own Little Black Book A mindless observer flipping through Red Channels would not find anything shocking, significant, or suspicious throughout its 213 pages. This small book, published in 1950 by the American Business Consultants, initially looks like an attractive collection of rà ©sumà ©s, complete with a person’s name, occupation, and a comprehensive listing of various activities in which the person was involved. These â€Å"rà ©sumà ©s,† however, were not made to make a person look appealing to an employer. In fact, if one’s name were found in this book, they would most certainly not be employed, or if they were employed, would be fired. Developed by three ex-FBI agents, Red Channels was America’s Holy Book of the 1950’s. It was referred to and analyzed, being the basis of every major decision in politics, media, and music. During this era, the majority of American citizens thought that this special book was a tool of protection for America, weedin g out influential Communists who were dangerous to their government and way of life. Yet this potent book was in reality harmful to society and illegitimate for a number of reasons. First, the book’s overt discrimination caused people to lose their jobs or their reputation, ultimately violating certain constitutional rights: the right to privacy, the right to property, and freedom of speech and association. Second, the book was the American Business Consultants’ corrupt means to extract profit, undermining the alleged â€Å"goal† of this publication to protect America’s interest. Third, the booklet added to the public ho... ...New York: Thunder's Mouth Press/Nation Books, 248, 254-255, 702. Capaldi, Jim. (2002, February 20). Pete Seeger Appreciation Page [Web site].

Character Analysis: Alias Grace, Margaret Atwood

Grace Marks being the protagonist of the historical novel Alias Grace matures and grows as most protagonist do. Grace goes through many stages in her life where she needs to adapt to the situation in order to not be taken advantage of. She Is either too naive, too deep in self-pity or too self-aware. She Is a dynamic character who goes from being a scared little girl Into a convicted murderess. The stereotype surrounding her being a woman – making her too fragile to take part In such a crime actually helps her and saves her from the noose.Like every proper girl Grace was very naive when It came to things of the sexual nature. When she observes Nancy dress to have some Ink-Sis snuff stains she tells herself â€Å"she most likely slipped and fallen down† (262) She TLD understand where the stains could've came from, besides getting dirty doing house work. Throughout her story Grace speaks a lot about Mary Whitney and all she taught her regarding men such as ‘not sitt ing where a man just sat' and how street whore's made money. Unfortunately Mary died while going through an abortion, which ironically Grace did not understand at the time.All of this new information did scare Grace, until she finally realized how naive she really was when she was informed about Mr†¦ Skinner and Nancy relationship as to which she remarked â€Å"l was much surprised , and said so; â€Å"l was not so knowing as I thought myself, and could scarcely see the nose before my face†. (295-296) Grace started losing luck as soon as she decided to work for Mr†¦ Skinner. Chapter 23 in the novel is named â€Å"Snake Fence† hinting Grace is walking into danger. Immediately after she enters the town she is confronted by a stranger before being saved by Jeremiah (239).Once she began working in the new village she felt very isolated † . It struck me at once how very solitary I was, as I had no friends here except Nancy, if she could be called a friend . . .1 did not know where my family was, which was the same as having none†. (301-2), she also confesses tootsie Walsh, â€Å"l felt would cry again, and said simply, I have no friends here. † (303). Unfortunately Grace soon finds out that that sort of loneliness is nothing compared to what was waiting for her in solitary confinement, where she would soon have to learn how to entertain herself â€Å"l sing a song, Just to hear a voice and keep myself company†. 37) By the end of the novel grace becomes very self-aware of how people view her, she knows people view her as a type of romantic notion and tells Lydia â€Å"But If I laughed out loud I might not be able to stop; and also It would spoil their romantic notion of me. Romantic people are not supposed to laugh, I know that much from looking at the pictures†. (27) And later admits â€Å"l look at him stupidly. I have a good stupid look which I have practiced†. (43).Her role playing seems to throw ma ny off when It comes to her being guilty or not, because she is so deep into her role of playing the â€Å"Lady of complete truth to Doctor Jordan it would never be known, with all the role playing she admits to doing. Grace's character and Tattoo's feminist views play a big part in how Grace is portrayed throughout the book. Just analyzing Grace acutely one cannot miss how her traits and situations make her seem to usually be the victim. But then again, if this wasn't the case, her story wouldn't be so interesting to the masses.
