Emotional Brain Systems are critical for understanding the many facets Essay

Emotional Brain Systems are critical for understanding the many facets of emotional experience.Discuss with reference to the historical development of affective neuroscience - Essay Example Although feeling these emotions are normal part of being human, it is inevitable for some people to experience emotional disorders. In the absence of fully analyzing the normal brain function, it can very difficult to determine the main factors that trigger the sudden emotional changes. The study of affective neuroscience is very much focused on analyzing the relationship between the normal brain functioning with the human emotions and mood swings. Over the past 30 years, a lot of research studies were conducted to explore the significance of the brain system with different types of emotions including how the emotion is being processed in the brain despite the individual cognitive, motor behaviour, motivation, and language development (Dalgleish, 2004). The main purpose of this study is to examine the importance of studying the emotional brain systems as a way to enable us to understand the many facets of emotional experiences that we encounter each day. Upon going through the main discussion, a literature review will be gathered to enable the researcher compare and contrast the different historical point-of-view of other people with regards to the development behind the study of affective neuroscience. Emotional brain is basically â€Å"a part of the human brain that generates emotions† (Young, 2005). Upon examining whether or not the brain produces emotions in response to unconscious and conscious perceptions, LeDoux explained in his book entitled â€Å"Emotional Brain† that a test was conducted in animals revealed that the amygdale which is a small part of the limbic system is responsible in producing neuronal responses in case a frightening stimuli is present (Hendrix, 1997). Basically, there are two ways wherein sensory input can be processed by the brain as proposed by LeDoux. These are classified as the following: (1) high road; and (2) low road (Hendrix, 1997). The ‘high road’ transfers the nerve impulse straight from the ears

The effects of global recession on local economies Essay - 1

The effects of global recession on local economies - Essay Example Multinational and international industries, local industries, government establishments and the consumers themselves are all affected by the changes in the economic standing of the country. Global recession has a great impact on the value of local and international currencies, generally affecting end-users and households. In effect, the buying capability of the consumers goes down. The general concept in putting up a business is simple, to profit from it. However, this simple concept requires a lot of fields to be taken into consideration before investors or businessmen can make it happen. In a basic business planning, the structure of study for putting up a business or developing an existing one is as follows: investment, resources and raw materials, market demand and profit and loss forecast. Investment is the capital cost is one of the most common things that are taken into consideration in a large or small medium business setup (Northcott 1992). This is the total amount of currency or money a businessman or a corporation invests to put up or develop an existing business. The total cost of the investment will be a basis for the company to determine the total cost of their liabilities. There should also be funds or a part of the budget that goes to the emergency funds for unexpected situation. These are part of the investment cost and are called funds margin or more commonly known as petty cash. Although this is the type of fund that should be replenished every month, quarter or year depending on the initial business funding structure of the company. Its initial will still be included in the total investment cost. Resource is also one of the major factors to be considered in putting up or developing an existing business. Raw materials are products that are bought together for the use for production purposes (Blair and Hitchcock 2001). There are two major types of categories in the business industry: the

Changing The Competitive Landscape Of The Smartphone Industry Marketing Essay

Changing The Competitive Landscape Of The Smartphone Industry Marketing Essay Abstract Innovation can be defined as a process of converting opportunities into new ideas and of the wide application of these ideas in practice (Tidd, Bessant, Pavitt, 2005). The past decade saw constant innovations in ICT aimed at increasing self-efficacy of the end users of communication devices. Elements such as miniaturization and ubiquitous computing (Open Handset Alliance, 2007a) have literally brought the personal computer to the palm of the consumer, in the form of a smartphone. The smartphone is rich with features such as internet browsing, touch screens, mobile-camera, improved connectivity and entertainment with the capability to adopt new applications (Burgelman, Silverman, Wittig, Hoyt, 2009). Recent years witnessed an explosive growth in mobile subscribers, where in 2008 alone global shipments rose 28%, as the smartphone gained momentum in the mobile phone industry (Canalys, 2008). The next few years are predicted to show a compound annual growth rate of 13.5% in handset shi pments leading to 1.9 billion handsets at the end of 2012 compared to 1 billion in 2007 (DataMonitor, 2008). Today, due to its portability and versatility the smartphone is a key player that facilitates the integration of technology with modern consumerism as the end user is given the capability to engage many computational devices and systems simultaneously (Tsai, Wang, Hwang, 2008). Mark Weiser (1991) refers to this as Ubiquitous Computing. The demand for smartphone has been the key driver for innovations (such as the touch screen, internet browsing, Wi-Fi) in the mobile industry in the past decade and the Open Handset Alliance and the Android platform are recent products of such pursuits. This study analyses how the OHA and Android has and will alter the terms of competition in the mobile industry, with relation to Porters five industrial forces. The Smartphone Industry Industry Participants Analysing the industry value chain of the smartphone the key components can be identified as chipset manufactures (Intel) , infrastructure developers and platform manufactures (Microsoft, Palm, iPhone) who provide the hardware and software components for handset manufactures. Application developers produce the applications that run on the operating platform whereas content providers such as Google provide the information for these applications. Mobile operators such as ATT and T-Mobile distribute handsets and provide the subscribers with network connectivity. In 2006 the global handset market was an oligopoly dominated by 5 companies which accounted for 85% of the market where Nokia and Motorola together accounted for 58%. Traditionally manufacturers competed through design. The entry of iPhone 3G to the market in 2008 created a new standard by combining design, performance, utility and functionality (Burgelman, Silverman, Wittig, Hoyt, 2009). It is considered by some industry analysts to be a blockbuster where Apples market share increased from 3.6% in 2007 to 17.3% in 2008, making it the now second largest player. Googles Entry into the Smartphone Industry Established in 1996 as the brainchild of two Stanford University computer science graduates, Google is now considered to be a blockbuster concept that has expanded beyond its core business as a search engine to a portfolio of products and services (Bhattacharya, Gopal, Samad, 2009). Today, a vast majority of Googles revenue is generated through the companys advertising products, Adword and Adsense (99% in 2007 and 97% in 2007) (Burgelman, Silverman, Wittig, Hoyt, 2009) that provide targeted advertising on its search pages, by placing advertisements relevant to a search on the results page. Googles entry to the smartphone industry was facilitated by its acquisition of the start-up open source software firm, Android in 2005 (Business Week, 2005). This event was a result of Google identifying the future growth potential of the smartphone and its capacity for mobile advertising. Eric Schmidt, the Chairman and CEO of Google stated You carry your phone everywhere. It knows all about you. We can do a very targeted ad. Over time we will make more money from mobile advertising. (Schmidt, 2010). Open Handset Alliance and Android In November 2007 Google unveiled the Open Handset Alliance, a consortium of 34 companies in the mobile industry representing the industry value chain (Fig 1), consisting of multinational companies such as T-Mobile, HTC, Intel, Qualcomm and Motorola. The objective of the alliance was to create an Open Software, Open Device and an Open Ecosystem (Open Handset Alliance, 2009b) fostering open innovation for development of mobile technology based on the open source platform. Today the OHA has expanded its membership to 65 companies. Fig. 1: The Wireless Value Chain (Hendrix, 2009) In November 2007 OHA released Android, an integrated software pack consisting of the Operating System, middleware, user-friendly interface and applications and the Android SDK free to the development community. Open Innovation and Open Source Open innovation is innovating through the collective creative input and knowledge of internal and external resources (Chesbrough, 2003). Open source technology is one method of open innovation (von Hippel von Krogh, 2006). It grants the developer the ownership of the source code without a cost of license fee or royalties giving them the freedom to further develop and distribute the product free or at a fee (Open Source Initiative, 2010). The openness of the platform creates more advance and cheaper innovations with shorter time-to-value, improving RD productivity and creating better value for money for the end user (Open Handset Alliance, 2009b). The OHA was a value network fostering open innovation by pooling of knowledge and Intellectual Property of the members. Android, was its first product built on the Linux open source kernel (Open Handset Alliance, 2007a). The Competitive Industry Forces Michael Porter (1979; 2008) defines five forces that define the competitive dynamics of an industry by shaping the interactions within that industry. These forces can be defined as bargaining power of suppliers and customers; the threat if new entrants and substitutes and established industry rivals (Fig.2). These are the figures that drive the profitability of the industry in the short and long terms (Porter, 2008). Analysis of these competitive forces and their drivers will provide insight into the basis of the industrys profitability and future growth potential. The entry of Android and Google into the smartphone industry has significantly affected its competitive landscape. Through the creation of an open ecosystem and a wide developer community it has created a sustainable competitive advantage against non-Andriods. Fig 2: The Five Forces that Shape Industry Competition (Porter, 2008) The Five Forces of the Smartphone Industry Bargaining Power of Suppliers There are a number of players in the smartphone Operating Systems (OS) market, led by Nokias Symbian, followed by Apples iPhone OS X, RIMs (Research in Motion) Blackberry, Microsofts Windows mobile, Linux and Palm (Hashimi Komatineni, 2009). These OS developers charged a license fee from handset manufactures, which was usually a variable cost of $0.50 to $25.00 per handset shipped. Further, in order to build applications on a specific OS, developers required SDK (Software Development Kit) and an API (Application Developer Interface), essential support tools for which they paid expensive certification and at times high membership fees (Burgelman, Silverman, Wittig, Hoyt, 2009). Due to the high bargaining power of these OS developers the cost to handset manufacturers was significantly high. Porter (2008) identifies standardization as an avenue of reducing the bargaining power of suppliers, and it is essential for innovation in the mobile telecommunication industry (Tilson Lyytinen, 2006). In the past collaborative RD and sharing of intellectual property were means of standardization in this industry (Bekkers, Verspagen, Smits, 2002). Android was developed to achieve an industry-wide standard in open source code making it freely available to all. By establishing OHA for this purpose creates an environment for open innovation reducing development, distribution and time costs of parallel innovation. The open nature of the Android platform makes it fully adaptable on any handset which triggers a high demand for the Android OS, which in turn reduced the bargaining power of the suppliers of OS. Bargaining Power of Distributers In the smartphone industry the distributers mainly consist of the network carriers who sell the phones to subscribers as a part of a mobile service plan. The bargaining power of the distributers is high since they have a large variety of handset manufactures with different features to select from. Although the failure of the Google Android may be due to a multitude of factors one key reason was their decision to sell the phone in their own web store independent of a carrier, in an attempt to shake up handset retailing . They changed this strategy by introducing the Nexus One in Vodafone (UK) in April 2010 (Parker Waters, 2010). Handset manufactures try to gain leverage through branding, networking and advertising to generate brand loyalty. iPhone for example has a very strong brand community. However the entry of the Android phone has created a new buzz word among subscribers, which gives members of the OHA a higher bargaining power over other handset manufactures. Another key aspect that affects carriers is the new avenue of voice communication that is available in the smartphones due to the Wi-Fi capabilities and applications that are provided such as Skype and Google Voice. With time this would reduce talk time over the carriers network impacting their revenue. Recently iPhone blocked Google Voice on its platform (Menn, 2009). Through collaborative innovation OHA has built a standard platform (Cusumano, 2010) and reduced RD costs of parallel innovation and increased time efficiencies. These economies will eventually flow to the end user creating higher value for money giving Android phone makers a better bargaining power over their subscribers compared to their competition. Rivalry between Incumbents Within a few years of entering into the market the mobile phone became a commodity due to the competition in the market and the fast innovations that resulted in similar phones competing on price. When the smartphone entered the market it required a premium price for the added functionality of the phones. Now the creation of a standardized OS platform through Android has the potential to commoditize the smartphone. Since it was introduced to the market Android has emerged as a strong brand whereby every smartphone running on the Android platform is co-branded as an Android phone. The very 1st Android the T-Mobile G1, Motorola Droid and the latest HTC Magic are few such examples. This creates a convergence in branding between the members of the OHA further consolidating the smartphone industry through the alliance. The value network and open ecosystem that is OHA has a large potential for future developments in the smartphone industry due to the knowledge pool they have created. This is a critical asset for the members of the OHA over the other players in the industry. Further, having Google as a strong leverage in terms of branding, information and human resources adds to the benefit of the OHA. By introducing a standard platform for smartphones Android has reduced any competition between handsets over the OS, opening a new avenue of competition, which is applications. One of the key issues that arise between incumbents in the industry is the Intellectual Property violations. Apple recently sued HTC for 20 patent infringements over HTCs Android phones (Gelles , 2010). Barriers to Entry The main barrier for the smartphone industry for a new entrant was the significant fixed costs of RD and advertising. The introduction of Android has reduced these barriers significantly. First, by freely providing the SDK to the development community any new entrant can use this OS without a cost. Further the applications that are developed for the Android phones are highly adaptable and open. Therefore they can be adapted by any new entrant. Similar Apples Apps Store, there are multiple applications that are available with no cost. Further the Android brand is a powerful platform upon which new entrants can leverage their marketing.

Use of the Classical Tragic Mold in Shakespeares Macbeth :: Macbeth essays

Macbeth: The Use of the Classical Tragic Mold in Character Development In Shakespeare's tragedy, Macbeth, there are many characters. Only one character stands out, and his name is in the title of the play. Macbeth's character was made in the mold of the ancient Greek tragic hero. Besides being endowed by Shakespeare with an abundance and variety of potential traits and characteristics, Macbeth also follows the Classical Tragic Mold, which is presented with a hefty supply of hubris, and in this case, ambition. Because Macbeth follows the Classical Tragic Mold, he is a Classical Tragic Hero. The first step of the Classical Tragic Mold is recognizing the problem. The problem in Macbeth is not a true problem that presents itself outwardly. The problem for the character of Macbeth is deciding if he should listen to his ambition and kill Duncan. At first, he ponders reasons why not to kill his king. He at first thinks that he cannot kill him because of four reasons: Macbeth is Duncan's subject, Duncan is a good king, they are blood-related, and Macbeth is his host. These reasons dissuade Macbeth at first, but later Lady Macbeth convinces him, by questioning his manhood, to commit the dastardly crime. When he finally murders Duncan, the problem comes to closure. But, even long before then, the next step in the mold had begun: the descent into the abyss. The "decent into the abyss" is the second step in the Classical Tragic Mold. It is started with Macbeth's second soliloquy. This is after Macbeth hears from Duncan that Malcolm was to be named the Prince of Cumberland. "The Prince of Cumberland! That is a step on which I must fall down, or else o'erleap, for in my way it lies ... Let not light see my black and deep desires." (Shakespeare, 281). This quote from the soliloquy indicates that Macbeth has, indeed, told himself that he will commit the murder of Duncan, although he doesn't actually admit it until his wife pressures him to do so. With this decision, the reader (or audience) reads (or sees) that Macbeth is straying from the righteous path, and descending into the abyss, even though he is keeping his feelings to himself. His decision to murder Duncan tarnishes his "war hero" image and casts it in an ominous shadow. The third step in the mold has two parts and is known as Transformation and Transcendence. The character of Macbeth goes into Transformation during his fourth soliloquy. "...I have lived long enough. My way of life is fall'n into the sear..." (Shakespeare, 343).

Central Evaluation Unit Essay

The XIII Directorate of the European Union has a Central Evaluation Unit (CEU) which is tasked with evaluation of applications for grants from academics under its â€Å"cooperation and foundations† scheme. This scheme distributed relatively small grants to fund cooperative research between universities in the EU. All applications were sent to the CEU’s processing unit (CEUPU) by university liaison officers (ULOs) who are based in around 150 universities. The process flow of the CEUPU can be shown in the following page. As can be seen, the turnaround time can be shortened even more if the checkers will have direct access to the ULOs and coordination done directly. This can be achieved by use of email with the secretaries just copy-furnished. Also, the document tracking can be automated so that everyone knows where the documents are at any given time, using the identifier code that has been established for each application. In all, the application will be handled by the following people: 1. The ULOs who receive it and send to CEU. 2. Receipt clerk that checks that forms are complete. 3. Coding staff – set up a unique identifier for the application, encodes the data in the system. 4. Senior secretary that assigns the application to the next available checker. 5. Checker assesses the application. Half of the time, there is a need for additional information or data, and this must be conveyed to the secretary. 6. Secretary sends a query to the ULO 7. ULO secures the info from the applicant and sends back to secretary 8. Secretary sends to checker assigned 9. Checker decides 10. Auditor composes and sends acceptance/rejection letter. The problem of the CEUPU process is that there are too many steps and people involved in the process. First, the process can be automated and the application documents scanned. Then, the file can be sent electronically to the checkers so that they can be evaluated. Direct communication by the checkers to the ULO can be made for any inquiries/ additional data needed. Auditors prepare the acceptance or rejection documents ULOs receive application for grants Additional info and requirements sent back Request letter sent File sent to secretary who then makes a request for the collection of any information missing or additional information required Yes NO Checker evaluates the application Decision is made by the checkers to accept or reject Additional information needed? Senior secretary of the checkers assigns file to the next available checker 8 receipts clerks check each application for completeness of all necessary forms Applications arrive from 150 ULOs, placed in the â€Å"in-tray† NO YES Pro forma front sheet attached to documents 2 clerks place identifier on the form and encode it into the information system COMPLETE?

Free Essays on Walt Disney

As Walt entered his mid-60s, he didn't seem to be slowing down. In fact, he appeared to be speeding up. He decided to create four exhibits for the 1964 World's Fair in New York. Why? So that he could experiment with new ideas particularly Audio-Animatronics while using other people's money. The Mr. Lincoln attraction he developed for the State of Illinois was one of the hits of the fair, and allowed him to take Audio-Animatronics a giant step forward. His other exhibits done for General Electric, Pepsi-Cola, and Ford were also hits at the fair. Meanwhile, he was working on other plans for the future: a ski resort called Mineral King was to be built near the Sequoia National Park. He considered a tourist site that might be called Walt Disney's Boyhood Home in Marceline, and even bought up properties there. Neither Mineral King nor Walt's Boyhood Home actually came into being. But his plans for a new kind of university were more successful. Declared Walt, "A completely new approach to training in the arts is needed. That's the principal thing I hope to leave when I move on to greener pastures. If I can help provide a place to develop the talent of the future, I think I will have accomplished something." He certainly did. Dubbed CalArts, an amalgamation of the Chouinard Art Institute and the Los Angeles Conservatory of Music, it would educate students in all facets of the arts dance, music, drama, visual arts, and film.

But though Walt was excited about all of these efforts, their scope paled in comparison to the so-called Florida Project a gigantic effort set for an area twice the size of Manhattan Island in the middle of Florida. The Chouinard Art Institute, merged with the Los Angeles Conservatory of Music, became CalArts Walt points to the sheer scale of his vast "Florida Project" Of course the Florida Project would include a theme park lik... Free Essays on Walt Disney -BIOGRAPHY During a 43-year Hollywood career, which spanned the development of the motion picture medium as a modern American art, Walter Elias Disney, a modern Aesop, established himself and his product as a genuine part of Americana. David Low, the late British political cartoonist, called Disney "the most significant figure in graphic arts since Leonardo DaVinci." A pioneer and innovator, and the possessor of one of the most fertile imaginations the world has ever known, Walt Disney, along with members of his staff, received more than 950 honors and citations from every nation in the world, including 48 Academy Awards and 7 Emmys in his lifetime. Walt Disney's personal awards included honorary degrees from Harvard, Yale, the University of Southern California and UCLA; the Presidential Medal of Freedom; France's Legion of Honor and Officer d'Academie decorations; Thailand's Order of the Crown; Brazil's Order of the Southern Cross; Mexico's Order of the Aztec Eagle; and the Showman of the Worl d Award from the National Association of Theatre Owners. The creator of Mickey Mouse and founder of Disneyland and Walt Disney World was born in Chicago, Illinois, on December 5, 1901. His father, Elias Disney, was an Irish-Canadian. His mother, Flora Call Disney, was of German-American descent. Walt was one of five children, four boys and a girl. Raised on a farm near Marceline, Missouri, Walt became interested in drawing at an early age, selling his first sketches to neighbors when he was only seven years old. At McKinley High School in Chicago, Disney divided his attention between drawing and photography, contributing both to the school paper. At night he attended the Academy of Fine Arts. During the fall of 1918, Disney attempted to enlist for military service. Rejected because he was only 16 years of age, Walt joined the Red Cross and was sent overseas, where he spent a year driving an ambulance and chauffeuring Red Cross official...

CSR in Nokia Company Essays

CSR in Nokia Company Essays CSR in Nokia Company Essay CSR in Nokia Company Essay In the last few years, more organizations are spending a fortune on their corporate social responsibility. This is increasing growing as a result of customer relationship and interest shown by the consumers in both products and service. Consumers are not Just having a brand loyalty but are monitoring the company in places where are operating to see If they will be environmental friendly. In other to successfully scrutinize the firm, the managers of this company are evaluating their Impact on the people and the environment. Monika has done reasonably well and still setting target or future year in other to fully implement recommendations and research result. Corporate Social Responsibility is of the best way to monitor the progress and face the challenges confronting them. Every well-to-do organization has a role to play to sustain or add value to the economy where they operate. Every company that intends to grow and succeed must care about the people and the society, e. G Must be socially responsible. This is why a company like Monika, Invested so much in other to see changes reflected In the way they do business in the community where they operates and changes In the mobile industry. The transformation is noticeable as Monika has brought a lot of Innovation to the mobile Industry and in the process of Investing and Influencing this change, there are specific areas where the company will always face Issues and the degree of challenges defers depending on the region where its being operated. Some of the challenges faced by Monika in the process of operating included but not limited to the following:- Energy Conservation Monika has consistently reduced the electricity it generated to operate overtime. Accordingly 40% of the electricity used by Monika comes from renewable energy sourcesl . Waste Management Monika has reduced the landfill waste by more than half since 2008 and the company has achieved 98% reduction as at 2012. Material The company is working towards sustaining the use of recycled materials. As at 2012, It Is using about 66% recycled materials on packaging and working towards increasing to 100%. Nooks, 201 2) Other factors affecting Monika are In the area of health safety, product use, logistic and suppliers. This Is not peculiar to Monika but to every organization where they value the Corporate social Responsibility (CARS). In other to understand the factors and the challenges faced by Monika, it is imperative to SE the external factors such as the Politic al, legal, social and the technology to identify and understand the market conditions where the company is localized, and thus work out modalities that could help or sustains Monika global brand. POLITICAL Even though the core basic aspect of Ionians business Is connecting people via mobile data communication, it is important for Monika to understand each terrain where their company Is domiciled. In view of this, It Is pertinent for Monika to understand the political landscape of the economy as the government must not be partial In the dealings with corporate companies. If there Is a good political structure in an economy, there is a tendency for Monika to grow but where the environment is This is one of the biggest aspects of mobile data Communication Company. The legal system differs from one country to the other and thus Monika needs to understand the concept doing things right. It may be impossible to avoid legal matters in as much as contracts, trade, agreements and taxation issues are involve, but Monika can study each country mode of operations better before appending contract, defaulting on tax issue. As rightly put We go beyond current legal compliance, not merely taking it a saline but as a starting point for further improvement. Our goal is for our devices to contain no substances of concern. We continuously review and update our substance list to comply with any new requirements or restrictions. Moreover, we continuously explore and introduce new environmentally-friendly materials. (Monika, Report 2012). SOCIAL The social factor is a very important determinant aspect to a successful Ionians operation. This will determine the willingness of people to be able to afford to buy Ionians phone. The segmentation of the population will determine which age group guys what? This will be influenced by the purchasing power of the people. E. G. N Africa, majority of the youth prefer to own about three (3) phones, one of which is the Ionians phone due to the durability of the phone battery as most places do not have power to generate electricity on their own, others will prefer the shape of the phones while others are more concern with the content of the phone. But coming to the Middle East, majority of the youth do not have more than one phone but will prefer a classic or stylish pho nes. People per capital income will also show their purchasing ewer, whether more people can afford to buy a new Monika phone or not. All these are part of the social factors affecting Ionians operation and growth expansion. TECHNOLOGICAL FACTORS Monika believes so much in investment into mobile technology and the company has spent significant amount of money on technological advancement. Without a continued innovation and research, a company cannot survive and this is where business environment values innovation. People prefer to have a phone with all-in- one mobile functionality. It is one of such investment in technology that is displayed n the New Monika Lamina with 42 camera MSP. CONCLUSION For Monika to have survive this far means that the company understand the challenges being faced and thus needs to continually study the political terrain of where they are operating, understand the legal aspect and strive to improve the social standard of the people while investing more in mobile technology. As stated in the Monika report, sustainability is about unleashing the potential of mobile technology to help people build better lives and a better planet. And its about minimizing possible negative impacts of our activities. (Monika Report, 2012).

The Relationship Between Electricity and Magnetism

The Relationship Between Electricity and Magnetism Electricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force. Together, they form the basis for electromagnetism, a key physics discipline. Key Takeaways: Electricity and Magnetism Electricity and magnetism are two related phenomena  produced by the electromagnetic force. Together, they form electromagnetism.A moving electric charge generates a magnetic field.A magnetic field induces electric charge movement, producing an electric current.In an electromagnetic wave, the electric field and magnetic field are perpendicular  to one another. Except for behavior due to the force of gravity, nearly every occurrence  in daily life stems from the electromagnetic force. It is responsible for the interactions between atoms and the flow between matter and energy. The other fundamental forces are the weak and strong nuclear force, which govern radioactive decay and the formation of atomic nuclei. Since electricity and magnetism are incredibly important, its a good idea to begin with a basic understanding of what they are and how they work. Basic Principles of Electricity Electricity is the phenomenon associated with either stationary or moving electric charges. The source of the electric charge could be an elementary particle, an electron (which has a negative charge), a proton (which has a positive charge), an ion, or any larger body that has an imbalance of positive and negative charge. Positive and negative charges attracts each other (e.g., protons are attracted to electrons), while like charges repel each other (e.g., protons repel other protons and electrons repel other electrons).   Familiar examples of electricity include lightning, electrical current from an outlet or battery, and static electricity. Common SI units of electricity include the ampere (A) for current, coulomb (C) for electric charge, volt (V) for potential difference, ohm (ÃŽ ©) for resistance, and watt (W) for power. A stationary point charge has an electric field, but if the charge is set in motion, it also generates a magnetic field. Basic Principles of Magnetism Magnetism is defined as the physical phenomenon  produced by moving electric charge. Also, a magnetic field can induce charged particles to move, producing an electric current. An electromagnetic wave (such as light) has both an electric and magnetic component. The two components of the wave travel in the same direction, but oriented at a right angle (90 degrees) to one another. Like electricity, magnetism produces attraction and repulsion between objects. While electricity is based on positive and negative charges, there are no known magnetic monopoles. Any magnetic particle or object has a north and south pole, with the directions based on the orientation of the Earths magnetic field. Like poles of a magnet repel each other (e.g., north repels north), while opposite poles attract one another (north and south attract). Familiar examples of magnetism include a compass needles reaction to Earths magnetic field, attraction and repulsion of bar magnets, and the field surrounding electromagnets. Yet, every moving electric charge has a magnetic field, so the orbiting electrons of atoms produce a magnetic field; there is a magnetic field associated with power lines; and hard discs and speakers rely on magnetic fields to function. Key SI units of magnetism include the tesla (T) for magnetic flux density, weber (Wb) for magnetic flux, ampere per meter (A/m) for magnetic field strength, and henry (H) for inductance. The Fundamental Principles of Electromagnetism The word electromagnetism comes from a combination of the Greek works elektron, meaning amber and magnetis lithos, meaning Magnesian stone, which is a magnetic iron ore. The ancient Greeks were familiar with electricity and magnetism, but considered them to be two separate phenomena. The relationship known as electromagnetism wasnt described until James Clerk Maxwell published A Treatise on Electricity and Magnetism in 1873. Maxwells work included twenty famous equations, which have since been condensed into four partial differential equations. The basic concepts represented by the equations are as follows:   Like electric charges repel, and unlike electric charges attract. The force of attraction or repulsion is inversely proportional to the square of the distance between them.Magnetic poles always exist as north-south pairs. Like poles repel like and attract unlike.An electric current in a wire generates a magnetic field around the wire. The direction of the magnetic field (clockwise or counterclockwise) depends on the direction of the current. This is the right hand rule, where the direction of the magnetic field follows the fingers of your right hand if your thumb is pointing in the current direction.Moving a loop of wire toward or away from a magnetic field induces a current in the wire. The direction of the current depends on the direction of the movement. Maxwells theory contradicted Newtonian mechanics, yet experiments proved Maxwells equations. The conflict was finally resolved by Einsteins theory of special relativity. Sources Hunt, Bruce J. (2005). The Maxwellians. Cornell: Cornell University Press. pp. 165–166.

Magnetic Resonance Image(MRI) Research Paper Example | Topics and Well Written Essays - 2000 words

Magnetic Resonance Image(MRI) - Research Paper Example The very large cost of MRI machines and their large size and specialized installation requirements acts as a deterrent to wider use of this technology. There is work underway that promises reduced costs and size of MRI machines, especially in the form of specialized machines for the scan of extremities such as wrists and ankles. The success of this effort could lead to wider use of the technology. Keywords: Magnetic Resonance Imaging, diagnostics, magnetic pulse 1. Introduction: The first Magnetic Resonance Image (MRI) was produced in 1973 and the procedure has now become a rapidly growing medical diagnostic tool for the medical profession. Over 30 million MRI procedures were done in the US in 2010 and new advances in technology is making specialized MRI procedures available for screening for a wider range of diseases and medical conditions each year. The human body can be considered to be essentially made up of three types of material; bone which is hard and made up of minerals such as calcium, soft tissue including muscles, flesh, blood vessels and organs such as liver, kidney, heart and lungs and fluids including blood and air. The field of diagnostic imaging started with the discovery of X-rays in 1895 by Wilhelm Rontgen. Even today, over two-thirds of medical diagnostics are done using X-rays. X-rays are ionizing radiations and the image is captured on a photographic film. X-ray images are good for viewing bones but the resolution for viewing soft tissue is often inadequate. The invention of Computed Tomography (CT) sought to address this limitation by using digital images in place of photographic plate and to manipulate the images for contrast and brightness to distinguish various types of soft tissue from each other (Ostensen, 2001). Ultrasound or ultrasonography was developed as the safer technology for viewing soft tissue and body fluids in the 1950s and 1960s. In this technique, sound waves of frequency between 3.5 MHz and 7 MHz are generated using a transducer or â€Å"probe†. Sound waves passing through human body get reflected when it passes from one type of tissue to the other. The reflected sound wave is picked by a microphone built into the same probe housing as the signal generator and a computer image of the internal tissue is created in real time. The medical professional can move the probe over the body area to see the changes in the image and also freeze the image for recording. Using ultrasound, it is possible to see images of blood flow through arteries and veins and see heart valves opening and closing. Ultrasound equipment is comparatively inexpensive and is safe as compared to X-rays. The interpretation of the ultrasound images however requires trained medical professionals and there is high risk of incorrect diagnosis (Ostensen, 2001). Ultrasound has no known side effects and is safely used even for examination of an unborn fetus. Ultrasound waves do not pass through air and are therefore not effective fo r examination of the stomach or the intestines. They also cannot penetrate bone and therefore are not used for areas with bone covering such as the skull. In obese patients, excess body fat sometimes makes ultrasound examination difficult as the reflected sound

Personal Statement Essay Example | Topics and Well Written Essays - 750 words - 7

Personal Statement - Essay Example In order to achieve our goal, we have hosted several events in this quarter, such as the Kickoff, the UPS event, getting students to go to the ALPFA events at UW Foster, and the joint potluck with the International Students Association. The biggest event was a speech from Nancy Koeper, the president of the northwest region of UPS. The event gave me an opportunity to demonstrate my leadership skills. I was supposed to inform all the students in our class of this event. Moreover, I was required to help set up the place where the event took place. Everything went so well, and the event was extremely successful since over 200 students were there to listen to Nancy’s speech. Even though I did not solely contribute towards the success of this event, I felt so proud of myself. I had taken part in ensuring the event was successful. This was a great move towards my future goal of being an eminent leader. Participating in planning for this event enabled me develop skills in different aspects. To start with, I improved on my public speaking skills since I had to make an announcement in classes to let many students know about this event and get them to participate. I had to address the whole class, which helped me get rid of my fear of public speaking. Additionally, I built many valuable relationships with my schoolmates. Before I joined the club, most of the people I hung out with were Koreans. This club activity enabled me to build relationships not only with professors, but also with many other students from different countries. I had more opportunities to be exposed to new cultures, which helped me mingle harmoniously with other students. Most of all, I re gained confidence in myself. Although I had experiences as a member of student council in high school, I lost confidence in myself when I realized I had poor English communication skills. However, my roles in Business Leadership Club have enabled me rebuilt trust in my

Solar PV on a Lifeboat Essay Example | Topics and Well Written Essays - 1500 words

Solar PV on a Lifeboat - Essay Example On the other hand, there are alternate ways to power the life boat in case emergency. Solar energy and wind energy are always available during any condition and these two renewable resources can be used to power a life boat. Solar and wind energy are not only environment friendly but also cost little. Moreover, solar and wind energy are not going to end as it is most concerned factors with diesel. Solar and wind energy are efficient source of energy as there is no operational cost. Solar energy is good for the life boats as solar panels are light weight and available is different sizes and shapes. Flexible solar panels are best suited for the inflatable life boats. It is most efficient technology for the life bots and can be used in combination with other technologies. In combination with the diesel power engines, the system will immediately switch to solar panel supply unit. The designed solar panels will have higher efficiency, waterproof layer and can resist a higher pressure during launch of life boat. An alternate energy sources is solar thermal energy. With the help of this technology water the temperature of water can be increased. In general, evacuated tubes and flat plate solar heat collection panels are mounted on the rooftops or on open regions to collect the solar thermal energy. For the power generation sector, molten salt or some other such material are utilized to attain maximum energy output from evacuated tubes. Molten salt stores the excessive thermal energy during day and gives it for the power generation during night. In some colder regions, two systems are utilized; antifreeze rust proof liquid is pumped through the flat plate collects or tubular collector to make the system running at low temperatures. Solar geysers are also installed with the evacuated tube collector to collect the hot water during night. Solar thermal is an efficient process to increase the temperature of water. The system

Clouds Seeding Essay Example | Topics and Well Written Essays - 1000 words

Clouds Seeding - Essay Example This paper takes a closer look at the concept of cloud seeding, the types, uses, and impact on the environment (Keyes 3). The main objective of cloud seeding is to cause enhance the precipitation through rain and snow and reduce the formation of hail and fog. This technology initially launched to research on and to monitor the climatic conditions of various regions in the world has been widely adopted by world’s leading economies with the main objective of negating the effects of extreme weather conditions. Under normal circumstances, harsh weather conditions are mostly experienced in the temperate countries especially during the winter and summer (Keyes 3). Although several methods of cloud seeding exist, the most common categories are the aerial cloud seeding and ground-based cloud seeding. Aerial cloud seeding involves the use of light aircrafts in the modification of weather at a considerable height from the ground. Ground-based cloud seeding on the other hand, entails the launching of intended substances into the earth’s atmosphere to carry out the same purpose. Irrespective of the procedure used to conduct cloud seeding, the underpinning idea is the same as it is the same process conducted in different procedures. Since the essence of cloud seeding is to promote the precipitation of condensed cloud, the methodology involves the injection of certain substances or chemicals into the clouds with the most commonly used being dry ice and silver iodide (Keyes 3). In some cases, the use of propane has proved successful although scholars from certain quarters questioned its efficiency. Since for successful could seeding to take pla ce there has to be super cooled water, the use of silver iodide has solved the problem through its ability to stimulate freezing nucleation because it is crystalline in nature. Research shows that dry ice and propane perform better than silver iodide as far

English lesson 6 Essay Example | Topics and Well Written Essays - 750 words

English lesson 6 - Essay Example This is the reason for the argument by some scholars against the attainment of human longevity, because they acknowledge the inability to resolve diseases, which eventually cause death. Even so, as humans further research on longevity, they tend to move closer to achieving immortality. But because of the immature and unwise reasons for immortality, the author discredits it, citing the unpreparedness of humans to handle the associated challenges. As such, the author uses figurative language, repetition and irony to appeal to the reader’s pathos by arousing fear, doubt and disapproval on the attainability and attractiveness of immortality. This emotionally appeals to the reader’s appreciation of significant human longevity as having limits and not necessarily being a good thing. McCarthy extensively uses figurative language to appeal to the readers’ fear by suggesting that immortality is dangerous to human life. The author uses metaphorical comparison of â€Å"a h ighway of immortality† to instill fear of immortality to the reader (McCarthy 544). Highways are known to be wider and smoother than other roads, prompting reckless driving that poses the danger of crashes and subsequent injuries or loss of lives. In the same way, McCarthy considers immortality as a hurried idea which poses dangers to humans. Instead of improving on the quality of human life, it could end up destroying it. In fact, by comparing it to a kind of life that does not have â€Å"a weigh station of wisdom,† McCarthy (544) argues on the immaturity of the idea of immortality. Normally, weigh stations are meant to check on the vehicles transporting cargo to ensure that transporters abide by the set load limits so as to avoid damaging the roads. Thus, the use of this figurative language in this context suggests the recklessness in the pursuit of immortality without appropriate checks, which in turn exposes humans to the associated dangers. The author’s choi ce of examples enables her to sample similes that arouse disgust on immortality among the readers. The example of Steven Austad’s comparison of humans to an object, specifically a car, suggests that immortality would cause humans to lose their humanness and in turn be objectified (McCarthy 546). In order to keep a car on the move, the older worn-out parts need to be replaced with newer and more effective ones. In a similar way, in order to keep humans alive forever, their aged body parts would be replaced with fresher ones. Even though scientists are already replacing parts of human body so as to achieve healthier lives, the simplicity of replacement that this figurative language exhibits makes this argument doubtable and unreal; it makes it sound disrespectful to humanity. It portrays humans as simple objects that could be fixed as simply as a car would. This comparison that objectifies humans, likening them to a car, would most likely disgust the reader. This will subsequen tly portray immortality as an aspect that would cost humans their humanness, hence portraying it as unattractive. Repetition of words has also been used in this essay to emphasize the argument on longevity having limits. When describing Dr. Leonard Hayflick’s view on significantly increased longevity, McCarthy notes that â€Å"it won’t happen, it can’t happen, and if it did happen it would be a bad thing† (546). Without being categorical on moderate human longevity, this negation repetition of the word,

Fidel Castro vs Adolf Hitler Essay Example | Topics and Well Written Essays - 500 words

Fidel Castro vs Adolf Hitler - Essay Example Adolf Hitler ruled Germany as a dictator and earned his position through politics whereas Fidel Castro is a revolutionist who overturned the American backed government in Cuba. Fidel Castro fought a revolution for the people of Cuba whereas Adolf Hitler wanted everything for himself. Hitler was a determined man who had the aim of conquering the whole Europe whereas Castro does not have any such aim of conquering the world. The people of Cuba still admire Castro because of his policies whereas many coups were organized to overthrow the government of Adolf Hitler because of his dictatorship. Along with these certain both leaders also share certain characteristics which revolve around their personality. Both Hitler and Castro are known as dictators in the history of this world because of their firm belief in communism. Both are at times designated as killers because under their regime they are held responsible for the killing of many people. Hitler had a plan of killing all the Jews and is considered to be responsible for the death of nearly 40 million people and Castro has the same desire of killing any individual who raises a voice against him. Another special characteristic which both the leaders shared was their hate for the United Nations.

Effects of Regeneration in the Urban Core

Effects of Regeneration in the Urban Core General Overview Urban decay, usually associated with deprived areas, tends tend to be a characteristic of poorer communes, reflecting their low earning power and susceptibility to the higher unemployment rates associated with changes in the structure of the national economy (Skifter Andersen, 2003). The a feeling that buildings are physically falling into a state of decay particularly in some areas more than others, often results in an excrescence of dilapidated and vacant buildings. By remaining vacant, buildings are generally targeted for commercial signage and vandalism unless subjected to a population change or economic restructuring (McGregor and McConnachie, 1995; Skifter Andersen, 2003). The redevelopment of decaying, run-down or underused parts of urban areas with the intention of bringing new life and economic vitality is crucial in maintaining a market position (Bolton Council, 2009). Redeveloping these structural units, however, may not be an easy task, as a set physical as well as casual mechanisms likely to be different in every area, are also accentuating the problem of urban decay. According to Skifter Andersen (2003), one of the major causes of urban decay is the decline of the local economy. The changes in the structure of the national and international economy can directly or indirectly influence the local economy as outlined in Haggetts Cumulative Decline Model (2001). Certain government intervention and planning policies with regard to the industry and alterations in the locational preferences of the industries to better equipped sites are also assumed to be among the primary causes of decline by increasing the gap between the core and periphery. Similarly, the population age structure in most Western countries is changing with an increasing number of elderly dominating the demographic chart (Commission on Growth and Development, 2008). This disinclinati on of the population is likely to remain in the highly urbanised areas resulting in a number of blight properties that are likely to fall into a state of disrepair if structural investment keeps lacking. Perhaps, following Myrdals Cumulative Causation theory (1972) might help inject vigour into the local economy from the institutional set-up (Fujita, 2004). Nonetheless, this process of urban renewal, through which environmental quality redevelopments occur in derelict urban areas, is highly contested. This chapter reviews selected literature that concerns the effects of regeneration in the urban core of a settlement with regard to the value enhancement and positive externality of building refurbishment while considering the social and economic implications. Urban Regeneration Urban regeneration most likely to take the form of public policy in order to regulate urban processes, attempts to improve the urban environment through renewal (Couch et al., 2003). Although seeming fairly simple and straightforward, Home (1982) describes the concept of urban regeneration as involving complex socio-economic, environmental and political issues, with no profession or academic disciple claiming control over it. Roberts (in Roberts and Sykes, 2000) defines urban regeneration as a vision which leads to the resolution of urban problems and which seeks to bring lasting socio-economic, physical and environmental conditions of an area that has been subject to change. Broadly defined as a process that prevents the urban fabric from starting or continuing to deteriorate by improving the urban fabric, urban regeneration is fundamental to the structure plans established by the Malta Environmental and Planning Authority in 1998 and 2006. According to the Priority Actions Programme/Regional Activity Centre (PAP/RAC, 2004) of the Mediterranean countries, the aim of urban regeneration projects as a solution to this phenomenon in developed is to promote: â€Å"return to the city, revitalise the city centre, restore activity in a fiercely competitive international context, and implement initiatives to improve the quality of the environment operating in a wide sense towards a smart growth†. Such systemised and planned action concerning certain parts of a town would mean injecting new vigour into an area. Skifter Andersen (2003) argues urban regeneration would transform, strengthen and recreate places to act as a catalyst for further investments for the benefit of the local community. By concentrating public resources and private investments on specifically designated area may turn an area to a great appeal (Adair et al., 2000). However, urban regeneration is not only concentrated around property-led and retail-led regeneration but also through cultural regeneration to transform the city as a form of urban recreation (Evans, 2001). According to Evans (2001), arts and cultural industries can distinguish themselves by restoring identities and economies with other lifestyles. Whilst Calxton and Siora (2008) recognise the retail sector as offering opportunities and employing a wide range of different socio-economic groups, they argue that retail-led regeneration appears to provide a key reconnection to economic opportunity by engaging in direct employment and additional investment for a community and its residents. Furthermore, Claxton and Siora (2008) sustain that the most successful developments are those supported by the local authorities where planning or economic development departments work together. On the other hand, Rubin and Taylor (2008) question the enormous institutional corporate power of certain chain stores that might have some influence on the planning system and in regeneration projects. According to them, the benefits from such regeneration are overstated as this type of regeneration creates an inverse system that extorts money out of the local economy resulting in serious consequences for small local businesses. Pitkin (1963) sustains that as an important trait within various Mediterranean communities is the urban ethos, the city is depicted as a place of cultural richness, civilisation and civic pride (Leontidou, 2000). Strengthening this argument, Florida (2003) suggested that as social ethos is becoming increasingly dominant in most entrepreneurial and growing regions, it is attracting creative people to the city and accentuating the processes of gentrification. Additionally, Ley (2003) also accentuates the importance of cultural and lifestyle of the middle class, who value the preservation of the historic core and the utilisation of exceptional commodities. Bailey et al. (2004) suggests that culture-led regeneration has only been effective when associated with commercialised identities, thus stressing the need for economic investments and retail establishments. Hiller (2000) suggests that for waterfront regeneration with transformation of the urban environment with luxurious residences a nd gentrified neighbourhoods must be create jobs through a number of office towers as well as shopping centres, included in most projects. As cities are never still, Lancaster (1995) had previously argued that they are places where people strive to overcome negative effects and create hope in the place that history has located them. According to Dunn (1998), the consumer culture might therefore encourage residents to disattach themselves from their particular area and associate themselves to the new global culture irrelevant of the location. Bailey et al. (2004), disagrees and argues that cultural forms of consumption can actively enhance and enliven local communities. Bailey et al. (2004) goes further by suggesting that it is the people who live in the city themselves have to engage in regenerating the city rather than the planning policies. Kantor et al. (1997), stresses the significance of local urban democratic conditions in creating inclusive governing that can influence the local communitys ability to participate and have a reach in the business. Gentrification As defined by Kennedy and Leonard (2001), gentrification involves the processes of reinvestment and revitalisation to enhance the physical and socio-economic components of cities. In this relationship, higher income households settle in that settle in the area, upgrade the physical and socio-economic component of lower income residences. Smith (1987b, p.463), specifically stated that the crucial point with regard to gentrification is that: it involves not only a social change but also, at the neighbourhood scale, a physical change in the housing stock and an economic change in the land and housing market. It is this combination of social, physical, and economic change that distinguishes gentrification as an identifiable process/set of processes. Furthermore, Wyly and Hammel (1999, p.716) add that the process of gentrification complements: class transformation of those parts of the city that suffered from systematic outmigration, disinvestment and neglect, or neglect in the midst of rapid economic growth and suburbanisation. Badcock (2001), argues that today the process of gentrification and restructuring have become so interrelated together that they have formed the broader transformation known as revitalisation. Furthermore, households of median and higher incomes generally value the preservation of the historic core and contribute to raising the areas ethos (Ley, 2003). Therefore, employment in the tertiary, quaternary and quinary sectors of production, usually associated with having a university degree, is a key indicator of gentrification according to Ley (2003). In other words, the post-modern lifestyles of consumption are the solution towards revitalisation of a location through the processes of gentrification. Consequently, the process of gentrification can be said to be the outcome of the range of responses to the new economic and social opportunities that arise from prior dispositions of the social classes (Bridge 2001). On the other hand, Smith and Williams (1986) were particularly concerned with displacement and the side effects the middle class is having on the lower working class through the processes of gentrification. Although the extent of the problem is not agreed upon, Sumka (1979) argues that displacement of the working class through rent increases was undoubtedly a major issue. More recently, Blomley (2004) outlines that the social mix the processes of gentrification bring with them tend to expose the working classes to several equalities in the social hierarchy as interaction between the owners and tenants in gentrified neighbourhoods seems to be limited. Slater (2006) argues that this process can lead to social segregation and isolation when trying to revitalise a neighbourhood. Yet, according to Sigworth and Wilkinson (1967) the beneficial effects to the community through gentrification outweigh the issues of social segregation which can be resolved through several policies. Ideal Scenario In a society where the absence of building care culture is increasing, prompt maintenance would help make aging buildings less problematic to rehabilitate as it is often the case that such buildings are found in a state of disrepair with various safety problems. Throughout the 1970s, many of the European countries had already started emphasise the gradual renewal process of rehabilitation rather than focusing on the massive redevelopments simultaneously (Wood, 1991). Thomas (1977), suggested that making way for redevelopment would give an opportunity to replace any substandard buildings, any clashes with regard to the land-use, as well as any environmental nuisance. Although in essence the process of redevelopment causes a lot of inconvenience as it dislocates people (Sumka, 1979; Smith and Williams, 1986; Blomley, 2004), redevelopment can help utilizing the full potential of a site as well as exploiting the beneficial effects to the community such as solving the problems related to social segregation (Sigworth and Wilkinson, 1967). Amongst the main problems that dominate the list for the issue of urban renewal, the lack of institutional planning (Adams and Hastings, 2001) and unfair reimbursements (Kam et al., 2004). This raises the question of whether it would be eloquent to redevelop rather than to rehabilitate certain properties in some areas. It was proposed that the decision making on whether to rehabilitate or redevelop is generally influe nced by six aspects namely; political, legal, technical, institutional, social and economic forces (Walker, 2002). According to Olson et al. (2001) and Hobman and Bordia (2006), the influences of the professional work background on the attitudes towards a renewal project can also make a difference. For instance, building surveyors are said to consider the structural conditions of a particular building as the most vital concepts of consideration in a regeneration process. Conversely, the town planners tend to give more importance to the impacts of the project in the visual quality and micro climate of the neighbourhood rather than the structural conditions of a building (Olson et al., 2001, Hobman and Bordia, 2006). Despite these converging views, it is evident that the implementation of an urban renewal strategy especially when done on a massive scale would include a strong financial input. This would also have to be coupled with adequate public resources, and a determined commitment to solving to the urban dereliction problems while aiming towards increasing the social and economic benefits and fostering entrepreneurial activity (Hamnet, 2000; Skifter Andersen, 2003; Calxton and Siora, 2008). In such circumstances, it is also advisable that there should be improvements to the infrastructure, the transportation system as well as the environment that should all coincide with the renewal development that has the support of all social partners (Adair et al., 2000). Yet, as such conditions rarely occur, policy makers must shape their development plans based upon the constraints they face at the particular moment in time. Williams (2006) suggested that in order to ensure a more successful project, t he ruling authority can also use its powers relating to property development to influence the planning, the infrastructure and the compulsory purchase powers together with the availability of public land assets. When trading land for example, it is not a rare occurrence that one party missing from the market forum and thus the scenario of a compulsory purchase might be required in order for the renewal project not to be brought to a halt because by the private economic forces (Williams, 2006). To redevelop or to rehabilitate? Specifically on property-led redevelopment, Harvey (1992) highlighted that the timing of redevelopment projects depend on three essential issues being; the value of the current existing use of the land resource, the current value of the best of alternative use, and the cost of rebuilding. As the use of property is not irreversible, property has the potential to be redeveloped and converted into another type or usage to suit the expected socio-economic demands at a given time (Gunnerlin, 2001). According to the structure plan issued by the Malta Planning Authority (PA) (1998), there is a need: to use land and buildings efficiently and consequently channel urban development activity into planned developed areas particularly though rehabilitation and upgrading of existing fabric and infrastructure. Notionally, if the present value of the existing use of the land resources is greater than the present value of the best alternative use, redevelopment would not take place since it would not be financially viable, and the rebuilding costs would affect the occurrence of urban renewal. This explains why sometimes redevelopment in the old, urban core is less attractive to the developers (Harvey and Jowsey, 2004). As for the option of rehabilitation, which would mean securing the existing structure, it was concluded that it would only be advantageous when a number of conditions are met (Pugh, 1991). This would mean that the service life of a building would be prolonged by another thirty to fifty years. Furthermore, the value as well as the interest rate of the existing building would also have to be high. Additionally, Pugh (1991) argues that if the direct and indirect costs of rehabilitating are considerably less than those incurred by rebuilding, then the developer would be more tempted to rehabilitate rather than redevelop. Ratcliffe (1993) also estimated that the costs of renovating a building can amount to twenty-five percent less than starting a new building project and thus making it more attractive for developers. Aikivuori (1994) points out that refurbishments may sometimes be required when there is a need for change in the land-use as well as when there is a need to increase or secur e the market value of the building. Additionally, this would also help to preserve the existing building and its externalities that may be important in inducing a culture-led regeneration. Challenges facing the renewal process Housing has long been regarded as a durable commodity (Wieand, 1999), yet, like any other physical commodity, properties are subject to deteriorate as time goes by and eventually fall into a state of dilapidation if they are not properly maintained (Burton 1933). A number of previous studies have highlighted among of the main factors that would make a building deemed for renewal would be the serviceable environment (Sohmer, 1999). Others like Rosenfeld and Shohet (1999) have formed models to determine whether and when a building should be upgraded. This helped to reduce uncertainties and serve as an aid when deciding whether to upgrade or not. Nonetheless, one should not forget that there are always a set of constraints that are likely to slow or halt the process of urban renewal. The multiple ownership of a number of properties is one of them for example (Chun To Cho and Fellows, 2000; Galea Debono, 2009). So are the limitations on the development in the urban village core through the Urban Conservation Area (UCA) which restricts certain types of redevelopment projects. Additionally, it is also likely that there may be disputes in the process of resettling those affected and disagreements on compensation issues which make it more difficult for the private developers to find a compromise with the landowners (Sumka, 1979; Smith and Williams, 1986; Blomley, 2004). Furthermore, it is also often the case that the lack of a central governing body to implement redevelopment and private developers little presumptive power, end up with the developers having fragmented, slow progress (Gordon, 2004). Positive outcomes from urban regeneration Fundamentally, the process of urban regeneration would help to contribute towards the preservation of structures of architectural value and significant historical importance (Jim, 1994). A sustainable regeneration scheme should therefore endeavour to lesson social exclusion, boost economic reintegration as well as salvage architecturally rich buildings and edifices (McGregor and McConnachie, 1995; Skifter Andersen, 2003; Bailey et al.,2004). Otherwise, an urban regeneration project can be a source of conflict and thus it might prove valuable to develop a decision making tool to facilitate the planning process as suggested by Walker (2002) and Ho et al. (2004). Eventually, project regeneration proposals can be assessed and alterations can be made in order to achieve a higher rating for the plan which is subject to time, budgetary and other practical constraints (Ho et al., 2004). According to Kocabas, (2000a), evaluating the impact of protection planning would ideally assess outcomes against the physical, social and economic objectives. This should preserve the physical historic environment, the needs of the existing residents during the process of upgrading as well as determining whether the conservation process is economically viable (Kocabas, 2000a). On the other hand, Borja et al. (1997) showed that the socio-spatial outcomes of globalisation on urban areas varied according to the correlation between the technological and economic processes that form the core for this transformation. Whilst it is now widely accepted that no city can escape the reach of global economic and political forces (Sassen, 2000; Taylor and Walker, 2001), it is also clear that cities can upgrade their position in the global hierarchy by their strategic intervention (Clarke and Gaile, 1997). This was the case with Ireland in 1988, for example. With the help of the European Commission, Ireland reflected on the mistakes made through the demolishment of buildings in inner Dublin through the Greater Dublin Area Development Programme secured and managed the preservation of the built historical environment (Pickard, 1994). Essentially, the upgrade or upkeep of neighbourhood externalities is also thought to contribute to the migration and related change in a neighbourhoods economic status for two main reasons. Firstly, certain types of households may behave in ways that generate social capital and affluence for the neighbourhood influencing the demand for that location, thus, the process of gentrification (Ley, 2003). Likewise, certain types of households might also choose to migrate into or out of a neighbourhood based on the demographic and financial characteristics of their prospective neighbours because of the social status, irrespective of how these neighbours may behave (Rosenthal, 2008). In spite of this, it is important to recognise that raising a neighbourhoods economic status does not necessarily alleviate poverty but could simply force the existing low income residents to relocate to other areas of the locality. Jacobs (1961) argued that rather than being suffocated by urban regeneration, soc ial life should be revived, thus, the process of gentrification might not be always seen in a good light especially from those who are less affluent and other deprived sections of society (Sumka, 1979; Smith and Williams, 1986; Blomley, 2004). Therefore, building rehabilitation may garner more support as it causes less social disturbances (Needleman, 1966; DeFilippis, 2007). Achieving success through failure Amongst the good examples of successful waterfront regeneration projects that have managed to generate enough employment opportunities for the locals, Gloucester, Swansea, Cardiff and Liverpool immediately stand out in the United Kingdom (Jones and Gripaios, 2000). In these cases, a number of listed warehouses were refurbished and transformed to provide residential, office, retail, museum, marinas and restaurant facilities. Liverpools Albert Dock, for instance, has been so successful as a heritage site that was previously in a state of decay that it now receives around six million visitors yearly (Jones and Gripaios, 2000). From being a totally abandoned and neglected eyesore, the Albert Dock has now been turned into a visually pleasing environment with the most obvious and tangible manifestations of successful regeneration project in the United Kingdom. Canary Wharf in London is another successful redevelopment that even managed to generate 7,000 jobs for the locals (Danielsand Bobe , 1993). In spite of these successful cases of regeneration, the process of urban renewal still generates a great deal of heated debate especially when faced fierce opposition from the locals that fear that there would no significant improvement in their standard of living such as in the case of Canary Wharf in London. Quite rightly as Jeffrey and Pounder (2000) suggest, the physical improvement of a building is a fundamental element in achieving a successful regeneration project, however Hausner (1993), suggested that on its own it is not sufficient as the development of any project reflects the conditions and requirements of the area in which the project is located from a wider perspective. In addition to this, Moore (2002) sustains that the proactive use of this policy might even improve the local economic development and even create new working places, however, this might only be for a short while. Hemphill et al. (2004) argues that much of the research conducted in the United Kingdom ten ds to be critical as there is a persistent sentiment that urban policy has not really left many of the desired effects on the regenerated area. This had already been thought earlier as even though the inner-city redevelopments generally improve and enhance the degraded built environments, there is criticism that such projects only cater to certain sectors of society and particular locations such as waterfronts and thus these types of projects can fragment cities (Fainstein, 1994; Meyer, 1999; Marshall, 2003). Further criticism concludes that the stated goal of urban design and renewal is often forgotten as the concepts have become merely a marketing tool (Gospodini, 2002). Moreover, it is generally felt that the concept of urban renewal is too vague with the fusion of the traditional architecture, the landscape architecture, and the planning and civil engineering. As a result, urban renewal is said to be focused mainly on the marginal cosmetic aesthetics of the landscape rather than helping to sustain a better standard of living in the area (Inam, 2002). Hubbard (2006) added that the social as well as economic conditions of an area are usually worsened though the regeneration and gentrification policies that are meant to be beneficial. On a wider scale, Newman and Thornley (1996) had previously suggested that in contrast with other cities, the key European cities such as; Paris, Milan, Berlin, Frankfurt and Stockholm are underpinned by the factor of the international competitiveness rathe r than by the notion of urban policy and therefore the residents standard of living has nothing to do concept of urban renewal. Bentley (1999) went even further and argued that apart from the social, economic and environmental limitations, the concept of urban design is often manipulated by developers and public authorities to covertly hijack public space and neglect local conditions and values. Revitalisation projects targeted parts of the cities, such as decayed port areas and other post-industrial sites, for major redevelopments so that the area in effect becomes totally gentrified resulting in a residential area for the more affluent citizens rather than the whole society in general (Bentley, 1999). Proprietors awareness and involvement It is evident that one of biggest barriers when it comes to building maintenance is the owners awareness that find it difficult to realise the basic forms of decay and the resulting impact on the building material (Kangwa and Olubodun, 2003). To make matters worse, when action is taken, it is often the case that an inappropriate remediation technique is applied (Leather and Mackintosh, 1994; Forrest et al., 1996). Thus, any effective renewal system must be constructed upon well informed diagnostic skill structures. Chanter and Swallow (1996) and Davidson et al. (1997) have suggested that some of the main awareness problems apart from the variations in perceptions of objects of regular maintenance include the inability to tell whether inferior products or components are used to rehabilitate the building. In addition to this, they also add that the average owner is generally unable to determine the quality of work done by the traders and cannot judge accurately the extent of skill requ ired for a particular work. In the end they argue that the absence of a referral system within the local housing communities which would act as an initial contacts for advice and general information on housing maintenance. Consequently, it is often the case that waves of building depilation later turn into the process of urban decay that has been a major problem in most developed cities (Skifter Andersen, 1995). It must be recognised that the local inhabitants are fundamentally the problem solvers and play an important and useful role not only in implementing regeneration strategies but also in maintaining the socio-economic improvement of the neighbourhood over the years. As powerlessness is central to peoples experience of poverty and exclusion, the people in general are more likely to involve themselves if they can clearly see their contribution in the city (Joseph Rowntree Foundation, 2005). Throughout the last number of years, the local citizens have also been emphasizing that new developments should retain their own characteristic and identity in order to reflect their collective memories. Public consultation meetings are no longer satisfying the citizens as they believe that a comprehensive public engagement exercise for the project is required and more channels should be provided for them to express their views on the developments (Lee and Chan, 2008). Research has shown that in the absence of government intervention, property owners are prepared to improve their buildings and edifices since it would enhance the market value of the refurbished properties provided that there is enough information for people to take sensible decisions (Holm, 2000; Gregg and Crosbie, 2001). Besides from having restored building edifices, this type of refurbishment project is estimated to increase the market price of the property which leaves a good profit after deducting the costs of the refurbishment project (Chau et al., 2003). Improvements on the buildings especially on the facades are intuitively expected to have a positive impact on properties adjacent to the building because of the improved visual quality enjoyed by the nearby residents. Likewise, unsightly externalities are created by the unsightliness of poorly maintained properties, thus, refurbishing these poor maintained buildings should reduce or even counter the negative impact (Colwell e t al., 2000; Boyle and Kiel, 2001). Nevertheless, while everyone would benefit from improving the exterior conditions of the buildings, the market value of the properties improved first would have their value depreciated by the dire condition of the neighbouring properties and thus for an individual to take the first step would not be easy. As a result, the unimproved properties would experience an increase in value as a result of the nearby investments done by the others. Consequently, this might also lead to a market failure as the refurbishment process may never take off completely resulting in an investment which is less than what was desired (Hui et al., 2007). Should more information on the enhanced market value of a refurbished building be made available, then the long-term sustainability of a rehabilitation effort would be incorporated into the urban renewal strategies easily, however, one must not forget that the effects may not be felt until a long time. In this particular scenario, the authority in charge sh ould encourage and encourage developers and owners to instigate redevelopment. Ultimately, the process of renewal is a product of an incremental decision making as owners have to decide whether to rehabilitate or redevelop their built land which is subject to facing obsoleteness (Bryson, 1997). Concluding Remarks As authorities are widely considered as the ones responsible for the process of urban decay, they started to be seen as being unable to engage successfully with the private sector. With the rise of the new conservative movements, the local government started to be marginalised in favour of the private sector when it came to taking decisions (Gullino, 2008). This resulted in private sector being placed at the centre of the renewal activities as these kinds of projects are assumed to attract new financial capital (Bianchini et al., 1992; Loftman and Nevin, 1995). Despite the process of urban renewal through which environmental quality redevelopments occur

Mixer and Nozzle Process Description :: essays research papers

Mixer   Ã‚  Ã‚  Ã‚  Ã‚  The hot air that is forced out of the combustor and through the turbine continues to exit the engine at the rearward. Before exiting however, this air must be mixed with the cooler bypass air that did not go through the compressor and combustor. These two airstreams are mixed in order to quiet the engine.   Ã‚  Ã‚  Ã‚  Ã‚  To understand how air can create noise, first consider the way water splashes and makes noise when a wave crashes. In the same way, when two different air streams traveling at extremely high speeds and at different temperatures collide with one another, noise is produced. In addition to the air streams colliding, the air also collides with the components of the engine and nacelle. Another example of air making noise is when wind hits a house. Even in a wind storm with small wind speeds, wind makes rushing and a grumbling noise against the outside walls of a house.   Ã‚  Ã‚  Ã‚  Ã‚  In order to mix the two air streams, the mixer directs the air escaping from the combustor and turbine blades outward towards the stream of bypass air. This is accomplished by stators, or channels that direct the air flow. There are stators in several other places in the engine, but their function is to stop the rotational momentum of the air and force it to fly straighter. After having turned the turbine blades, the air is given a spiraling motion which decreases its velocity. The stators correct this by channeling the air towards the nozzle so that it can be expelled as exhaust.   Ã‚  Ã‚  Ã‚  Ã‚  The mixer must withstand temperatures of more than 3000 degrees Fahrenheit. It is made of nickel alloys which are engineered to withstand heat. Without this heat resistance, the mixer would either melt or suffer distortions and permanent damage. Although the mixer helps to reduce jet engine noise, it does not eliminate it entirely. The low grumbling sound of a jet is the result of the air mixing inside the engine and being expelled toward the rear of the aircraft. The air streams coming out of the rear of the engine also slap against the air outside the aircraft and even against parts of the aircraft itself. Nozzle   Ã‚  Ã‚  Ã‚  Ã‚  The main function of the nozzle is to create thrust. As the hot gases are expelled out the nozzle, they exert a force on the plane and propel it forward. Gas turbine engines operate according to Newton’s Third Law of Physics which states that for every action there is an opposite and equal reaction.
