Engineering ceramics (Research Paper Sample) Content: Engineering Ceramics First Name Last Name Course Name Instructorà ¢Ã¢â€š ¬Ã¢â€ž ¢s name Date Engineering Ceramics Ceramics are defined as inorganic but non-metallic materials that are of great value and importance to our lifestyle. These materials can either be metallic or non-metal compounds that have been suppressed to very high temperatures. The extreme temperatures make the ceramic possesses their desirable qualities of being hard, brittle and resistance to corrosion. Material engineers are people who design the different types of Ceramic. They also determine the processes in which these products can be made, and recommend the suitability of different types of ceramic in daily lives. Industrial manufacture of Ceramics is made by taking mixtures of clay, earthly materials, additives, and water and molding them into a shape that you desire or specified. The mold is then put inside a kiln and subject to very high temperatures. Once complete, the ceramic can be covered with decorative, paint, waterproofing elements as per the specification of the material engineer/manufacturer.[.

Dordrecht: Kluwer, 1997.] Modern engineering ceramic materials There are different types of advanced engineering ceramic materials. They are most categorized as per their applications which include nuclear fuel, window glasses, electronic devices, engine components, cutting tools among others. Generally, engineering ceramics are classified into the following; Metallic oxides: These include oxides like alumina, zirconium, and beryllium oxides. These materials contain metallic atoms as their primary elements. They have the following properties, Low dielectric loss, good toughness and high strength, high thermal conductivity at medium temperatures. They also resist to wear and tear. Glass-Ceramics; the glass ceramic are easier to work on and can be machined with steel tools. They permit light to pass through them and hence transparent, have different thermal conductivity depending on composition type. The glass ceramics are utilized in manufacture of glass windows, laboratory equipment, and electronics among many other devices.[. Clegg, David, and Robert McCarter. Ceramics. London: Shotlist, 1998.] Nitrides and Carbides: these are silicon nitrides, boron carbides, silicon carbides and tungsten carbides. These materials have these desirable qualities, they are resistance to high temperatures and thermal stresses and strain, yield high strength, good electrical insulation in the case of boron carbide ceramic. Tungsten carbides are excellent at thermal conductivity, resistance to abrasion and wearing off. These ceramics are mostly used for tool tips. Carbons and graphite: These ceramics are very common and readily available in the market. They have the following properties, excellent electrical and thermal resistance, self-lubricating, low density and chemical re-activity. They have a disadvantage of reduced strength unless where they are produced as a fiber. Carbon /carbon composites: have high strength and low thermal coeffi...

Hurt Locker and Ptsd - 1903 Words

The Hurt Locker and PTSD Post Traumatic Stress Disorder is an anxiety disorder that runs through our military system and is often vastly overlooked. It is a little-known mental health problem that is poorly understood. It can be traced back to the times of the Civil War and has been given names like shell-shocked syndrome, PTSD, soldiers heart, and combat fatigue. A soldier who has experienced combat or military exposure of any level of severity can be susceptible to this anxiety disorder and its symptoms. The Hollywood film The Hurt Locker, directed by Kathryn Bigelow, depicts the American soldier’s battles with PTSD and shows how drastic its effects can be.

If the face of Owen Eldridge was on an accused suspect’s file, it’d be difficult not to feel it wasn’t his fault. Another main character from The Hurt Locker who shows a connection with this political discourse is Sergeant William James. He is the main focus of the movie and is hated but respected by almost everyone. He is the badass of the film who does everything his own way, without help from anyone else, and gets the needed results. He is portrayed as the perfect soldier† because he shows no weakness and puts his life on the line even when he does not have to. There were only a few scenes in the film where he shows any sign of emotion, one of which was when he saw a familiar boy lying dead on a table. The boy had a bomb wired through the internal organs of his body and James thought it was the boy he played soccer with at base camp. James was hurt by this incident because he was so fond of the boy and saw that he was tortured and killed. Even though nothing would come of it, James dismantled the bomb that was wired inside theShow MoreRelatedAnalysis Of The Book Auschwitz 1502 Wo rds   |  7 Pagescreate inferiority.

In this article the personality traits of managers using different leadership styles are explained in terms of, and add to, the description of these styles. Members of a management team were assessed in terms of their preferred leadership styles and two groups were identified. Some of the managers relied on both transformational behaviors and active transactional behaviors with an absence of behaviors associated with passive styles. Trends were observed when comparing the profiles of the managers in the two leadership groups. Transformational leadership was defined in terms of the interpersonal more than the visionary aspect of leadership with interpersonal styles and work and soci al ethics being emphasized.

Ethnographic Film Essay Example For Students

Ethnographic Film Essay In making Ethnographic Film Essay ethnographers will inevitably be confronted with conflicting values and will be forced to choose to uphold some while neglecting others. The situation is complicated further when the films are intended for television screening and the audience is the general public; the ethnographic filmmaker then faces the task of producing something that is simultaneously ethnographically competent, entertaining, accessible to general audiences and ethical. Here I will examine two ethnographic made-for-TV programs: Masai Women and Kayapo Out of the Forest. In each of these programs the filmmakers were confronted with ethical decisions requiring them to uphold one value while excluding another. It is my intent to show that in ethnographic film making there can be no set formula for which filmmakers can prioritize ethnographic values and human ethics; each decision to uphold one value over another must be made in regard to the specific social and political context in which it is being made. Masai Womens filmmakers were confronted with two conflicting values when treating several aspects of Masai culture. On one hand the film was meant to be an ethnographic documentary and as such had its own set of ethnographic goals. These include portraying whole people and being as objective as possible. On the other hand, the filmmakers had to be cognizant of their audience, the general (British) public. Knowing that their audience was the general public had both advantages and disadvantages: while it gave them a unique opportunity to reach a wide range of people it also created a certain responsibility, since the film wasnt being shown in the context of any anthropological discourse on the subject. This isnt to say the filmmakers were limited because their audience were the ignorant masses but rather that they were dealing with a diverse audience. The film, to be successful, could assume neither that the viewers were educated nor uneducated; a successful television program appeals to many sensibilities. While depicting Masai culture these values came into conflict in treating several subjects. First and most striking was the subject of female circumcision: the topic was completely glazed over. In narrating the topic Melissa Llewelyn-Davies describes female circumcision as a joyous occasion, a rite of passage for Masai women, the equivalent to a white wedding in British society. The filmmakers reasoning behind this decision to not dwell on the subject was essentially a decision to adhere to one of the values described above, to be responsible and respectful in portraying a culture to open audiences; ethnographic filmmakers certainly do not want to create disdain for a culture based on practices that may seem adverse to western society. In adhering to one value however they were forced to abandon another, ethnographic completeness. In a film about Masai women, a female-centered film about the lives of women, the issue of female circumcision seems to me to be very pertinent and an important topic to explore. For instance, the girls screams are edited out, clearly in violation of ethnographic principle. Lleweyn-Davies also says that the practice is the female equivalent to male circumcision. It most certainly is not. If practiced on men female circumcision would amount to one-half to three quarters removal of the penis. Here, the point is that the issue is glazed over and made benign for the purpose of not offending the average western viewer. One topic more difficult to avoid in a discussion of Masai womens experience is the practice of polygyny. Here, the same conflicting values were confronted as are discussed above: on one hand the filmmaker wants to produce a film that is ethnographically whole in its description of cultural institutions, yet on the other hand the filmmaker must keep in mind the composition of the audience. In this instance Melissa Llewelyn-Davies chose to explore the topic at length in favor of the former value. She does however explore the topic with great sensitivity, choosing to ask the subjects how they feel about the practice themselves, rather than narrating . .udfca0687371aa0e129afed498b5c5aed , .udfca0687371aa0e129afed498b5c5aed .postImageUrl , .udfca0687371aa0e129afed498b5c5aed .centered-text-area { min-height: 80px; position: relative; } .udfca0687371aa0e129afed498b5c5aed , .udfca0687371aa0e129afed498b5c5aed:hover , .udfca0687371aa0e129afed498b5c5aed:visited , .udfca0687371aa0e129afed498b5c5aed:active { border:0!important; } .udfca0687371aa0e129afed498b5c5aed .clearfix:after { content: ""; display: table; clear: both; } .udfca0687371aa0e129afed498b5c5aed { 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; } .udfca0687371aa0e129afed498b5c5aed:active , .udfca0687371aa0e129afed498b5c5aed:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .udfca0687371aa0e129afed498b5c5aed .centered-text-area { width: 100%; position: relative ; } .udfca0687371aa0e129afed498b5c5aed .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .udfca0687371aa0e129afed498b5c5aed .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .udfca0687371aa0e129afed498b5c5aed .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; } .udfca0687371aa0e129afed498b5c5aed:hover .ctaButton { background-color: #34495E!important; } .udfca0687371aa0e129afed498b5c5aed .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .udfca0687371aa0e129afed498b5c5aed .udfca0687371aa0e129afed498b5c5aed-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .udfca0687371aa0e129afed498b5c5aed:after { content: ""; display: block; clear: both; } READ: Dissabiliteis Essay In making Kayapo: Out of the Forest, Terrence Turner faced a somewhat different dilemma, yet it was a dilemma of conflicting values nevertheless.
