The Mobile Phone Essay Example For Students

The Mobile Phone Essay Since the beginning of time, man has been inventing things; demand for technology is sky high and what the public wants, the public gets. Nothing, however, can compare with the sudden boost of the 21st centurys best invention yet, the mobile phone. Communication has taken on a new meaning, and currently you cannot take a stroll down a typical street in Europeand not see one. Mobile Phones have taken the world by a storm and their rising popularity has impacted the planet tremendously ( http://www.coursework.info). According to the U.N, 400 million mobile phones are in use globally, and 250,000 more are added to the list each day (http://news.bbc.co.uk/1/hi/sci/tech/470027.stm). How could one tiny communication source make such a difference? Why are these technical handsets so significant that they are owned by millions and millions around the world?

Over time, civilization must have gotten tired of all those long hazy conversations, and a horse and carriage system was born to deliver messages here and there. History came a long, long way, but eventually, communication through wires was introduced. For this we can give credit to Claude Chappe who invented the telegraph in 1792, and then Alexander Graham Bell in 1876, the first man to develop the communication of voices through wires. Communication History took its turning point, when in 1894 in Italy; a hopeful scientist Gulielmo Marconi created an invention called Wireless. This was where he tapped out a message in Morse code, and a bell rung on the other side of the room. From then on, scientists began to further investigate in this concept. Soon enough in 1935, an American scientist invented the first FM radio. This was all scientists needed to spring into action. Eleven years later, people were already beginning to communicate in moving vehicles and 37 years after that, the first call on the first Cellular Phone of the history was made in the year 1983. The word Cell in Cell Phone was created because in order for the system to work, cities would need to have been divided into cells, thus increasing the amount of frequency waves in the air so numerous people would be able to speak on the phone at the same time. This concept was first discovered and developed by Motorola, the first Mobile Phone Company in history. The success of the industry is displayed by the chief of the statistical compendia branch of the Commerce Dept., who states that the cell phone industry has shown remarkable growth over the decade, its doubled over the last three years alone. It is clear that cell phones are here to stay. From the simple plain model to the high-tech, picture-taking, video-recording, internet models, it is almost impossible not to have one in a demanding lifestyle. A couple years ago on my visit to England, I was literally shocked to find two girls my age that had cell phones; needless to say, in a matter of two, three years I happened to own one myself, including almost everyone I was surrounded by! The original purpose of mobile phones is obviously being diminished. They are now weaving themselves into the fabric of society, becoming fashion statements and now necessities rather than luxuries. Because of the colored fascias, aerials, covers, logos and ring-tones used today to accessorize the cell phone; its no big surprise that children at the age of 8 are demanding the new Ericsson PF768 from Santa, or that Nokia 8810 for their coming birthday. To validate this conjecture, recently, the internationally famous childrens animation corporation Walt Disney had released a new line of Mobile fascias in the market. These were criticized due to encouraging young children to such conceptions, especially when there were so many complications involved. These days, like the car you drive, the apparel you wear, and the size of your office, mobile phones are symbols of power and importance. A mobile, up on the pretentious social scale, alerts people that you are busy, 3310 3330 Personality Facias Groovy chick, drama queen, shopoholicdo these describe anyone you know? have personality, and a decent job. For many teenagers, a mobile phone symbolizes freedom. This is the purpose for which great deals of adolescents (ages 13-18) have mobile phones. Parents are much more comfortable with liberating their kids knowing that they will be able to contact them anywhere, anytime. The mobile phone is said to be included in each individual teens personality kit. In fact, it is almost like teens with mobiles are developing their own culture, from their own abbreviated SMS language, to the way your type of phone implies your social status. It is interesting, as teenagers seem to have enough of partition from adults without mobiles! .u85a73e51ad7f37f267798057c949f2b3 , .u85a73e51ad7f37f267798057c949f2b3 .postImageUrl , .u85a73e51ad7f37f267798057c949f2b3 .centered-text-area { min-height: 80px; position: relative; } .u85a73e51ad7f37f267798057c949f2b3 , .u85a73e51ad7f37f267798057c949f2b3:hover , .u85a73e51ad7f37f267798057c949f2b3:visited , .u85a73e51ad7f37f267798057c949f2b3:active { border:0!important; } .u85a73e51ad7f37f267798057c949f2b3 .clearfix:after { content: ""; display: table; clear: both; } .u85a73e51ad7f37f267798057c949f2b3 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u85a73e51ad7f37f267798057c949f2b3:active , .u85a73e51ad7f37f267798057c949f2b3:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u85a73e51ad7f37f267798057c949f2b3 .centered-text-area { width: 100%; position: relative ; } .u85a73e51ad7f37f267798057c949f2b3 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u85a73e51ad7f37f267798057c949f2b3 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u85a73e51ad7f37f267798057c949f2b3 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u85a73e51ad7f37f267798057c949f2b3:hover .ctaButton { background-color: #34495E!important; } .u85a73e51ad7f37f267798057c949f2b3 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u85a73e51ad7f37f267798057c949f2b3 .u85a73e51ad7f37f267798057c949f2b3-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u85a73e51ad7f37f267798057c949f2b3:after { content: ""; display: block; clear: both; } READ: The Importance Of Communication EssayIt is said that all over the world, within about 10 years mobile phones are predicted to outnumber traditional landlines. In many countries, inclusive of both rich and poor, already have this situation proceeding. Even Africa, the poorest continent in the world is in on the game. In Rwanda, cellular phones occupy over 58% of the market, while in Cambodia, the figures are even higher! The cell phone corporations boast up to 72% of all subscriptions. Both Rwanda and Cambodia did not have such extensive fixed lines in the first place, so it wasnt too costly and was not a matter of refurbishing either. Cambodia, facing war has its own personal reasons as well. Apparently it is much easier and safer to arrange and set up cellular antennas across the terrain swamped with land-mines. In other developing countries that face natural disasters and such, Mobile phones are definitely practical. For example, Mozambique suffered intense and sudden flooding in the year 2000. In order to find rescue aids and temporary security, they had to call relief urgently for the citizens that were made homeless. For the people of Gujarat, San Francisco, and El Salvador that undergo earthquakes, cell phones are needed desperately as well. Mobile phones do not only do that, but they encourage a step towards the improvement of the economy in Developing countries. It is possible that things may finally begin to take its toll in these countries. Earlier this year I was hiking in the Ngorongoro, breathing in the sweet swell of nature and trying to feel in tune with the Maasai way of roughing it. I was flabbergasted to find that when we were at the top of a mountain, the three Masaais that were guiding us whipped out their cell phones to see if they had any reception! This proves that the Mobile phone concept as being a necessity has even touched the lives of Maasai in the wilderness. In EMDCs (Economically More Developed Countries), cellular phones, along with the Internet, are becoming the nations prime communication sources. The business world revolves around these techniques to obtain what they want, when they want. Mobile phones are a large part of the market as well; companys such as Nokia, Ericsson, Motorola, Siemens, etc have created several jobs for people. Because Developed countries do have the money, their willingness to spend on luxurious conveniences such as this is not too surprising. In Addition to all the accessories and such, of course! Admittedly, Mobile Phones are an extremely costly necessity. If it werent, the vogue would be spreading around the world at a much quicker rate than it already is. Setting up the cellular systems in ELDCs (Economically Less Developed Countries) is pricey enough, and then the added cost of antennas and the constant upkeep. This would not be a Developing countrys primary concern when half of its countrys people are possibly starving. Buying a mobile phone is also expensive. In addition, buying credit or having prepaid programs are highly costly as well. Citizens in these countries, particularly the more rurally living ones, would not be too eager to try a new gadget either. If, of course getting reception in these parts were possible. This is a disadvantage of cell phones; there may not always be signal where you want it. An aspect to think about in such countries would be culture. Certain African culture may not be as accepting as a person who has been living in New York all their life. This particular mentality may be due to specific ideology that believes in standing by natural resources and acquiring what God gave us. A rising problem occurring because of mobile phones is an increase in crime. Recent figures have shown stolen mobiles make up for about 50% of the robberies all over London. There were 700,000 mobiles stolen last year according to police records. The reason cell phones are so sought after by thieves is that they are easily sold in the black market for a good sum of cash. This, of course is in developed countries, so can you imagine how it must be in developing countries? Another disadvantage of mobile phones is the number of driving accidents. New research indicates that driving while on the mobile increases the risk of an accident. In Britain, at least 12 road deaths have been linked to cell phones. The reckless driving of uneducated and amateur drivers in ELDCs must cause worse results in this aspect. .ua890d57f218e8d4e422b92fc4e4f4440 , .ua890d57f218e8d4e422b92fc4e4f4440 .postImageUrl , .ua890d57f218e8d4e422b92fc4e4f4440 .centered-text-area { min-height: 80px; position: relative; } .ua890d57f218e8d4e422b92fc4e4f4440 , .ua890d57f218e8d4e422b92fc4e4f4440:hover , .ua890d57f218e8d4e422b92fc4e4f4440:visited , .ua890d57f218e8d4e422b92fc4e4f4440:active { border:0!important; } .ua890d57f218e8d4e422b92fc4e4f4440 .clearfix:after { content: ""; display: table; clear: both; } .ua890d57f218e8d4e422b92fc4e4f4440 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ua890d57f218e8d4e422b92fc4e4f4440:active , .ua890d57f218e8d4e422b92fc4e4f4440:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ua890d57f218e8d4e422b92fc4e4f4440 .centered-text-area { width: 100%; position: relative ; } .ua890d57f218e8d4e422b92fc4e4f4440 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ua890d57f218e8d4e422b92fc4e4f4440 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ua890d57f218e8d4e422b92fc4e4f4440 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ua890d57f218e8d4e422b92fc4e4f4440:hover .ctaButton { background-color: #34495E!important; } .ua890d57f218e8d4e422b92fc4e4f4440 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ua890d57f218e8d4e422b92fc4e4f4440 .ua890d57f218e8d4e422b92fc4e4f4440-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ua890d57f218e8d4e422b92fc4e4f4440:after { content: ""; display: block; clear: both; } READ: Diary of anne frank EssayMedical Hazards of Mobile Phones One of the most recent and hazardous discoveries that scientists have made about the cellular phone use is that it is potentially dangerous to the human being. Complaints have been made for unexplained headaches, ear and eye sight problems, feelings of nausea or dizziness, a tingling sensation on the skin and a numbness or redness to the face and neck (http://autoworx.freeyellow.com/report.html). People complained mainly of a burning dull feeling on the side of the head where they have been using their mobile phone. Apparently it tends to last several minutes after they made their call and may last for hours. Along with these indications, they may get feelings of nausea, instability in their vision and sometimes other symptoms. Scientists say that mobile phones may be linked to memory loss and even cancer due to the microwaves emitted. Although there are many theories towards this, there is no evidence. Some scientists claim that with one thousandth of a microwave oven, your brain cannot be cooked so there is a large chance these notions could be false. Scientists have also done animal studies that have brought up argument against the possibility of cancer. However, this is a fairly contemporary discovery, and until we can prove anything, we should not jump to conclusions. The Cellular Phone is now so intertwined into Society, that if it were obliterated, it would result in an immense crash. People would not know how to adapt their lifestyle into having no cell phones. In fact, the way society works has even evolved because of this tiny device. It is quite nerve-wrecking to think that so much of the world depends on this technical gadget. Even though there are so many disadvantages to having cell phones in this world, there are clearly many more benefits. Cancer is something that we may need to think and worry about in the future. However, the way humanity in general has been taught is to take things as they come; and thats most likely what theyll do. First it was the internet. Now its mobile phonesà ¢Ã¢â€š ¬Ã‚ ¦ What next? What will be the next discovery to revolutionize society?

5 Ways to Fend Off Difficult Coworkers

5 Ways to Fend Off Difficult Coworkers These aren’t the only strategies for dealing with difficult people- at work or anywhere else, but they’re a start. Make sure to keep in mind that difficult people are still people, and show them as much compassion as you can- within reason, of course. 1. Respect and ValidationIt’s what you would want, if the roles were reversed. No one is difficult on purpose. So give the pain-in-your-office the benefit of the doubt; you don’t need to agree with everything they say, but sometimes all a person needs is to be heard.2. SympathizeWalk a mile in their shoes. Just because they’re difficult doesn’t mean they don’t deserve a hand. If you can see the situation from their point of view, then maybe you can help steer them out of it. A little critical thinking, active listening, and a bit of compassion can go a long way.3. Don’t ArgueAn argument is easy, and almost always unproductive. Instead of anticipating what you’ll fire back wi th, try actually listening. Listening is easy and it will never escalate a situation out of your control.3. Counter with FactDon’t be argumentative, but you can help a difficult person reframe their more extreme statements with a little dose of reality. Turn hatred into frustration, â€Å"always† into â€Å"occasionally,† and desperate situations into constructive possibilities for change.4. Set a TimerNo matter how high your patience level, there are reasonable limits. Don’t let the difficult person hijack your entire day with their negativity. If you’ve tried all of the above and still can’t defuse the situation, it’s perfectly okay to set some boundaries. Say you have five minutes to chat, but then you both should really get back to work.5 Tips to Handle Difficult People

Implementation, Strategic Controls, and Contingency Essay

Implementation, Strategic Controls, and Contingency - Essay Example This research will begin with the statement that a strategic plan is a step by step instruction manual that explains how an organization will move toward achievement of its objectives and how it will inform its workers what is expected of them. Without effective strategic plans, an organization is unable to make its employees move along with harmony while understanding the company’s goals and milestones. This paper throws light on the implementation of this plan and explains the objectives, functional tactics, action items, milestones, tasks, resource allocation, and other important issues. The objective of this strategic plan is to search for some new services apart from filing and solving complaints of the clients, and implement those services. When a company decides to offer a new service, it has to make use of all the internal resources of the company as well as a lookout for opportunities in the external environment. The organization also has to look out for threats and m ust be prepared to face all kinds of disasters and losses. It has been proposed that Human-Care.org should implement a counseling service in which clients can have access to expert professionals in social and psychological fields. This service will benefit those clients who are themselves disturbed personalities and may be filing illogical complaints. Human-Care.org should focus on the short-term activities called functional tactics because these are a key to success in the long run. Four main functional tactics are: time (how much time will be dedicated to current activities?), specificity (how activities will be managed to achieve the strategic plan?), participants (who will be involved in the plan?), and empowering operational personnel (how personnel will be motivated and trained?).

Research paper analyzing the writiing style of Stephen King Essay

Research paper analyzing the writiing style of Stephen King - Essay Example On the one hand, critics question King’s writing style as â€Å"The Comic Strip Effect† and â€Å"The Disgusting Colloquialism† (Hoppenstand and Browne 2). On the other hand, King is also praised for his â€Å"dazzling† storytelling skills (Hoppenstand and Browne 2). Since 1987, most of his novels were chief selections of the Book-of-the-Month Club, which in 1989 made the Stephen King Library, and is dedicated to keeping King’s novels â€Å"in print in hardcover† and some were even produced as films, such as The Shining (Badley et al. 1). This paper analyzes King’s writing style. King’s writing style is described as seeking to terrorize, horrify, and lead his readers to gross-some reactions, which magnifies his use of ethos and pathos, while having logos residing â€Å"between the lines.† Stephen King is the King of macabre; he spins stories from â€Å"American nightmares† (Hoppenstand and Browne 2). As the king in this genre, he has ethos or authority in the ghastly dimension of human experiences: â€Å"His work has changed the horror genre and blurred the lines between horror and literary fiction† (Dyson and Bloom 5). His ethos conceals the logos of his stories. He writes about stories of real human conditions that not all horror stories touch upon. King’s thoughts go beyond the archetypal. His â€Å"pop† awareness and his campy humor entice the collective unconscious (Badley et al. 4). In Danse Macabre, King stresses the â€Å"cross-pollination of fiction and film,† and he categorizes his subject into four â€Å"monster archetypes†: the ghost, the â€Å"thing† (or human-made monster), the vampire, and the werewolf (Badley et al. 4). He uses references from classic horror films of the 1930’s and the 1950’s pulp and film industries (Badley et al. 4). He combines the gothic novel, classical fables, Brothers Grimm folktales, and the oral tradition (Hohne 95). During this time, the characters doubt the myths but need them in their lives; horror is particularly comforting and â€Å"cathartic† and the narrator marries the roles of physician and priest into the witch doctor as â€Å"sin eater,† who takes over the culpability and fear of the culture (Badley et al. 4). As a result, Stephen re-creates old monsters by adding a new sense of mystique. In The Uses of Enchantment: The Meaning and Importance of Fairy Tales (1976), psychologist Bruno Bettelheim stresses that the enchantment and horrors of fairy tales present existential problems in forms children can understand. King’s paranormal horrors have comparable cathartic and informative roles for adults; â€Å"they externalize the traumas of life, especially those of adolescence† (Badley et al. 4). Danse Macabre represents the externalization of these traumas, as a way of coping and survival. People have to analyze and read between-the-lines, nevertheless, to understand the themes of survival and adaptation in some of King’s novels. King writes to terrorize readers. King’s critics say that his success relies on the â€Å"sensational appeal of his genre,† which King eagerly confesses, because he writes to â€Å"scare people† (Badley et al. 4). His fiction is explicit, maudlin, and at times, known for conventional plots (Badley et al. 4). In Carrie, he writes about the opposite of Cinderella. It is the macabre version of dreams that can hardly come true for a society that denigrates women like Carrie. Furthermore, King’s humor is frequently unsophisticated and â€Å"

8 Principles of a Good Oral Communicator Essay Example for Free

8 Principles of a Good Oral Communicator Essay According to Lewis (1975), Communication means sharing messages, ideas, or attitudes that produce a degree of understanding between a sender and a receiver. Communication cannot take place until the receiver correctly receives and interprets the information and then respond. Oral communication implies communication through the mouth and includes individuals interacting using spoken words. Speeches, oral presentations and discussions are all forms of oral communications. Being a good oral communicator can enable you to inform, motivate, entertain or even persuade others to accept your points of view. There are many basic principles of being a good oral communicator. For the purpose of this paper I will briefly discuss eight (8) of these principles. Maintaining good eye contact with your audience, knowing your topic and purpose, showing emotion of passions and interest during your speech, presenting a rounded picture and speaking clearly and pleasantly in a conversational manner all contribute to a person being an effective oral communicator. Being prepared is of most importance when giving a speech. Know your subject. Thoroughly research your topic and prepare for possible questions. The written speech should never be memorized. See more:  Mark Twains Humorous Satire in Running for Governor Essay You will look stiff, sound uninteresting and bore your audience. Memorizing is a fatal mistake. It turns the speech into a mere recitation; and reciting is not nearly as effective as speaking direct to the audience. A speaker must be free to alter, omit, or add as he sees what his audience requires. If possible, make up index cards with notes or key phases to refer during your speech. It is very important to connect with your audience. Speak to your audience, listen to their questions, respond to their reactions, adjust and adopt. One mistake speakers often make is trying to prove they’re smart. When you stand in front of an audience, there is already a gap — you’re the expert, they’re not. By trying to impress your audience with your intellect, you create more distance and could come across as arrogant. Your job is to close the gap, not widen it. Add humour whenever appropriate and possible. Keep audience interested throughout you entire presentation. A public speaker should always anticipate objections. There will be members of the audience whose sole purpose is object to whatever is being presented. There will also be persons in the audience who might be knowledgeable about the topic you are presenting on. Be open to questions and let it be known that you ‘don’t know it all. ’ By being self-effacing, humorous and real, you become approachable and it’s easier to win over your audience. In turn, the more connected the audience feels to you, the more they’ll pay attention to what you have to say. Use words that are within your audience’s vocabulary or calibre. Do not try to impress them by using â€Å"big words† as they will not understand what is being said and will lose interest in your presentation. Maintaining sincere eye contact with your audience is a very essential part of giving a speech. It helps create a sense of two-way communication and shows that you are interested in interacting with your listeners. When you are looking at your audience, you should not stare and should try to scan the group, not looking too long at any one person or section of the room. You should try to vary the focus of your eye communication, trying to involve everyone in the group or each section of the room. In public speaking the management of the voice is very important. Some speakers speak too low and cannot be heard well in a large hall. Some shout, and their voices are drowned by the echoes. Some talk so fast that they cannot be followed; and some speak so slowly as to tire their hearers patience. The speaker should speak clearly, for all to hear; he should vary the intonation of his voice to avoid monotony and to enforce his meaning; and he should know when to make effective pauses. Also you should add inflection and emphasis to be effective in making your points. Communicate a little at a time. Simplify your messages. You are where you are because of the depth and breadth of your expertise. Your natural inclination will be to impart lots of that knowledge onto your audience. Resist it! Otherwise, you’ll bore and overwhelm your listeners with details they’ll never retain. Focus on conveying a few powerful ideas that they’ll remember. It is also beneficial for a presenter to present information in several ways. Use audio-visual aids or props for enhancement if appropriate and necessary. Master the use of the presentation software before your presentation. A presenter should speak with conviction as he really believes in what he is saying. Let your passion show. There is no substitute for authentic passion at the podium. When you believe in your message and have energy around your topic, it will ranslate to your audience. Above all else, be yourself up there! In concluding, a good oral communicator should aim to master the basic principles of public speaking. A speaker should know the needs of his audience and match his contents to their needs. Look pleasant, enthusiastic, confident, proud, but not arrogant. Maintain eye contact. Show appropriate emotion and feeling relating to the topic. Know his material thoroughly. Ensure that his speech will be captivating to his audience as well as worth their time and attention. The result will be a sharper central idea and a tighter, more coherent speech.

1.1 Background history Composite material is a multiphase materials which can be obtained through the artificial combination of two or more different materials to attain the properties that the individual components by themselves cannot attain. Composite materials can modify for many properties by appropriately choosing their components, proportions, distributions, morphologies and degrees of crystallinity, crystallographic textures, structure and the composition of the interface between components. Due to this properties the composite materials can be designed to satisfy the needs of technologies relating to the aerospace, automobile, electronics, construction, energy, biomedical and other industries. Therefore, composite materials has been used most as a commercial engineering materials [1]. There are some type of composites that can be classified according to the matrix material such as a polymer matrix composite (PMC), a metal matrix composite (MMC), and a ceramic matrix composite (CMC). Besides that, the composite also can be categorized according to the shape of the filler or the reinforcement for example a composite that has a particles as a filler is called a particulate composite and a composite with fibers is called fibrous composite [1]. Metal matrix composite (MMC) is a composite that contains continuous metallic matrix and a few percent of the material by volume represent the reinforcement [2]. The MMC offers some unique mechanical properties such as low density, high strength, and high stiffness, high wear resistance and other attractive properties. It also can offers the properties that are exceptional compared with those of any unreinforced alloys [2]. The metal matrix composites also can be classified in diffe... ...Al2O3 particles uniformly in aluminum matrix and for its ability to fabricate the material into almost any shape [3]. 1.3 Objectives 1.3.1 To fabricate alumina particle reinforced aluminum metal matrix composite by using powder metallurgy technique. 1.3.2 To investigate the effect of different weight percentage of alumina particle on physical and mechanical properties of aluminum metal matrix composite. 1.4 Scope of study The aim of this project is to investigate the effect of different reinforcement weight percentage (0wt%, 5wt%, 10wt%, 20wt% and 30wt%) of alumina particle on aluminum metal matrix composite. The composite will fabricate by using powder metallurgy technique which include mixing, compaction and sintering process. The testing involves in this project is microstructural analysis, density, porosity, hardness and coefficient thermal expansion (CTE).

The rubric can be found in your Unit Resources. Prompt Many teens and young adults have personal music players, such as MP3s, that allow them to take their favorite music with them wherever they go.Such devices require earbuds, and users can often be seen with at least one earbud firmly in place, listening to music as they go about their daily business. Some critics of these music players, however, argue that users tend to be isolated in the world of their music. Users, these critics say, do not really pay attention to what is going on around them; and they behave rudely when they carry on conversations with others while wearing at least one earbud. Assignment: Do personal music players such as MP3s isolate their users and hamper social interaction?Should such devices be set aside in some situations to promote social interaction and even safety? Plan and write a response in which you state your position and persuade readers to agree with you. Support your opinions with reasons and examples. Type your draft here. Have you ever thought about how possibly that iPod you have in your hands could be keeping you distracted from the world you live in? Well in fact I believe that’s exactly what it does. With all of these advancements in technology, especially in the Apple industry we h ave the newest, smartest, and fastest technology on the market in our hands.We can surf the web from anywhere, listen to music, take pictures, txt, call, and the list goes on and on. With all of this power in our hands it distracts us from our daily life. We have become so caught up in these gadgets that it isolates us. I believe that through the use of our iPods, mp3 players, or our phones, it hampers our social interaction. We become so caught up in the life we live through our phones that we miss out on the life that is happening right in front of our eyes. I am guilty of doing this. Just the other day I was at the mall sitting there listening to music and using my iPod.I would look up from my iPod every few minutes and notice how so much had changed and I didn’t even know it. There was nobody around me when I first sat down but after a few minutes I looked up to notice people all around me and I had no idea they were there. I was so caught up in my iPod that I missed out on what was happening right in front of me. It goes to show just how distracting and consuming this technology can be. I truly believe that sometimes we just need to learn to set whatever our source of technology is to the side and just be social.For example, while you are sitting in class at school and you have a teacher that allows you to text in class; it would be more beneficial for you to pay attention to what the teacher is saying rather than texting on your phone. It is way too distracting for you and the people around you; you miss out on what the teacher is saying and it affects you in the long run. Also, when the test rolls around, it would be nice to know the material, and if you were too busy on your phone, you would have no idea. It is clear that sometimes we need to learn to set aside our technology from distracting us.This is because what is going on in front of us is way more important. IPods, phones, mp3 players, etc. are all amazing devices and I am blessed to be a ble to own one. However, with all of this power in our hands it distracts us from our daily life. We just need to learn how to evaluate whether or not it is appropriate at the time to use them. It is not worth missing out on your life. So set the phone aside and enjoy what you have been missing out on all along. |Your Score |___ of 50 |
