Profile of Joycelyn Harrison, NASA Engineer

Joycelyn Harrison is a NASA engineer at the Langley Research Center researching piezoelectric polymer film and developing customized variations of piezoelectric materials (EAP). Materials that will link electric voltage to motion, according to NASA, If you contort a piezoelectric material a voltage is generated. Conversely, if you apply a voltage, the material will contort. Materials that will usher in a future of machines with morthing parts, remote self-repairing abilities, and synthetic muscles in robotics. Concerning her research Joycelyn Harrison has stated, Were working on shaping reflectors, solar sails and satellites. Sometimes you need to be able to change a satellites position or get a wrinkle off of its surface to produce a better image. Joycelyn Harrison was born in 1964, and has bachelors, masters and Ph.D. degrees in Chemistry from the Georgia Institute of Technology. Joycelyn Harrison has received the: Technology All-Star Award from the National Women of Color Technology AwardsNASAs Exceptional Achievement Medal (2000}NASAa Outstanding Leadership Medal {2006} for outstanding contributions and leadership skills demonstrated while leading the Advanced Materials and Processing Branch Joycelyn Harrison has been granted a long list of patents for her inventing and received the 1996 RD 100 Award presented by RD magazine for her role in developing THUNDER technology along with fellow Langley researchers, Richard Hellbaum, Robert Bryant, Robert Fox, Antony Jalink, and Wayne Rohrbach. THUNDER THUNDER, stands for for Thin-Layer Composite-Unimorph Piezoelectric Driver and Sensor, THUNDERs applications include electronics, optics, jitter (irregular motion) suppression, noise cancellation, pumps, valves and a variety of other fields. Its low-voltage characteristic allow it to be used for the first time in internal biomedical applications like heart pumps. The Langley researchers, a multi-disciplinary materials integration team, succeeded in developing and demonstrating a piezoelectric material that was superior to previous commercially available piezoelectric materials in several significant ways: being tougher, more durable, allows lower voltage operation, has greater mechanical load capacity, can be easily produced at a relatively low cost and lends itself well to mass production. The first THUNDER devices were fabricated in the lab by building up layers of commercially available ceramic wafers. The layers were bonded using a Langley-developed polymer adhesive. Piezoelectric ceramic materials can be ground to a powder, processed and blended with an adhesive before being pressed, molded or extruded into wafer form, and can be used for a variety of applications.

Multiculturalism And Polyculturalism From The Novel I...

In this essay I am going to examine examples of multiculturalism and polyculturalism from the novel â€Å"I Hotel† by Karen Tei Yamashita. For the examples I choose I am going to explain why and how these are examples of multiculturalism or polyculturalism. Also, I am goint to explain how the novel presents a new form of identification and how the examples of polyculturalism are related to such a new form of identification. I Hotel: A Novel, consists of ten novellas. Each novella introduces interesting stories of various social and ethnic movements, comprised of diverse participants, such as Asian Americans, African Americans, Native Americans, Latino Americans, Russian immigrants, college students, factory workers, intellectuals, etc., which orbit around a shelter in San Francisco for new immigrants and low income working class people of color, called the I Hotel. Based on then years of research and over 100 interviews with real people who were involved in the multi ethnic po litical movements, Yamashita seeks to illustrate people’s struggles to create strong political grounds for â€Å"hyphenated Americans,† as well as their frustrations toward the bureaucratization of ethnic identification as a tool for dividing people. In particular, Yamashita represents this period of civil rights movements as linked to the critiques of capitalism and solidarity along class lines, instead of focusing only on the cultural heritage of race and ethnicity.

How Harmful Is Air Pollution - 1799 Words

Question: How harmful is air pollution? Background: There are many different types of pollution, some are more visible than others are invisible. Another way of looking at air pollution could be any substance that can interfere with the atmosphere or the well being to survive in that condition. There are two different types of pollution, primary and secondary pollution. The pollutants that are a direct result of the process can be called primary pollutants. An example of a primary pollutant would be the sulfur-dioxide emitted from factories. Secondary air pollution are the ones that are caused by the reactions of primary pollutants. Generally, any substance that is emitted into the atmosphere is considered air pollution.. Humans cause the majority of the air pollution by doing many different activities such as driving a car, traveling by plane, and even working at factories. Man-made sources of pollution are called anthropogenic sources, which means â€Å"cause by the people†. If we keep breathing the polluted air , it can make us sick. Humans can experience a wide range of health effects from being exposed to air pollution. There are short term and long term effects from exposure. .

Impact of E-Marketing-Free-Samples for Students-Myassignment

Question: Discuss about the Impact of E-Marketing. Answer: Introduction In the modern-day world where people are business oriented, and almost every field of business has been exploited, proper marketing is what will make the difference between a successful company and a company that will flop. Any leading business enterprise in the world today spends much fortune of what it makes to market their products and services through various means especially advertisements (Kaplan Haenlein 2010). The change in technology has also influenced the way information about various companies is passed to potential clients. So, in this case, how has technology influenced the way various companies market their products. Is e-marketing the reason why many companies reach a wider market. Data Collection and Analysis For us to understand the impact of e-marketing, a few categories of companies were selected as the case study for this research. I collected information from the companies about their use of the internet to market the products that they deal in producing (Nicholls 2012). In analysing the information about companies that already established themselves, we take a look at the difference in their market performance before and after the use of e-marketing. For the analysis of the companies that are establishing themselves, we compared their performance with those that have not initiated e-marketing in their operation. Broad and Global Reach There are various businesses that have been established recently and have picked up fast to gain a considerable share of the market in such short time. Comparing these companies with similar companies that have not fully embraced the use of the internet as a vital marketing tool, they are steps ahead. The main reason behind these is the fact that these companies have the capacity to reach a big number of people (Kim Ko 2012). In a world of a population of around seven billion people, 2 billion out of this population are active users of Facebook. The recent years have seen a Facebook rise from just a social media platform to a very powerful marketing tool. Facebook has enabled many companies to reach a very large market both at a local level and at international level making it one of the most desirable marketing platform in the world today. Cost Effective. Given the fact that a business organisation has the capability to access a very large market from the internet without spending a lot of resources. The fact that they are able to access a large market with fewer resources assures that the cost of operation of the company is reduced to ensure that the company thrives and beats competition from companies that have not focused on marketing through the internet (De Vries, Gensler Leeflang 2012). Another internet marketing tool that is very important in the world today is the online business website tool, for example, eBay and Amazon. Apart from just marketing, these online platforms provide an interface in which the buyers and the sellers of the various products can freely interact. As a result, the cost of operation of this companies is greatly reduced as their sales increase and their globular market also expand vastly. That makes the online based business to grow rapidly and in a very short time beating other companies with the old m odes of operation. Easy Measure of Cost and Effect Tracking the growth of the business as a result of the marketing is very important so as to help us establish if the investments in marketing are bringing returns. using other marketing tools that do not involve the internet means that it would be really hard to track down the number of people reach and compare it with the changes that have been brought about by marketing. In simple words, it would be hard to determine the exact worthiness of your investment in marketing (Armstrong et al. 2015). Using online marketing tools means that it would be possible to make a follow-up and find out how many have received the information from the advertisements on the internet. One will, therefore, know to what level should the advertisements be carried so as to produce a certain amount of result. A company can also gauge its growth is attributed to the efforts that the company has put to carry out the marketing of its products. Conclusion Looking at the success that various companies have gained as a result of e-marketing we can clearly see its impact. This evident as we have seen in the case of the companies that have just established themselves through the social media marketing (Nicholls 2012). Also, the fact that two out of every seven people on earth use Facebook shows how online market reaches a lot of people. In conclusion, e-marketing has positively changed the phase conducting various business in the world today, and the future looks even brighter. References Chan, N.L. and Guillet, B.D., 2011.

Public Relation And Communication Samples †MyAssignmenthelp.com

Question: Discuss about the Public Relation And Communication. Answer: Highlights Public relation is an integral communication strategy that is instrumental in building a beneficial relationship between an organization and its publics. In other words, it is the process of communication that is executed by organization to communicate with its target audience by and through a medium (Grunig, 2013). Public relation is a persuasive business strategy to influence a group of target audience that is usually in the domain out of the manipulation, to promote an ideology and support it with validation with indirect promotion of any product. Public relation is an unpaid, unearned and credible form of advertising and is relatively different from the usual advertising activities. The sole purpose of Public Relation is to build trust and confidence of the publics by using well-framed language to manipulate and take control of situation in which an organization is publicly censured or its reputation being at stake. Public Relation uses media as the mediator, where media plays and controls the final account. Public Relation uses the informal techniques of accountability by informing or publishing articles that are of public interest or concern Public relation is a pre-organized strategy to consolidate the foundation or the reputation of any organization, brand or a product, with indirect means of advertising and selling. The tools to perform a PR activity are through press conference, meetings, newsletters, public events, social blogs, conventions and many more. PR activities are usually assigned to a person who has excellent skills in communication like verbal and writing with special ability to handle crisis and work under pressure. References Grunig, J.
