Rosencrantz and Guildenstern Existentialism

What if everything gets one nothing? What if it was true that man has the power to do whatever he pleases, but in the end all of it will mean – for lack of a better term – nothing? This school of thought is called existentialism, which is crucial in Tom Stoppard's play Rosencrantz and Guildenstern Are Dead – an absurdly written response to William Shakespeare's Hamlet. Rosencrantz and Guildenstern experience times of enlightenment, humor, and sorrow throughout their journey, leading them to ponder whether their livelihood actually has some sort of positive meaning. However, the ultimate gift of death crept up on them, without any explanation or hope, for all eternity. The ideas of existentialism are shown in the play through unstable identities, uncertain knowledge of the past, and anti-heroes which lead to Rosencrantz and Guildenstern’s ultimate fate – their feared deaths. Unstable identities in the play contribute to the idea of existentialism by making Rosencrantz and Guildenstern indistinguishable, emphasizing their need for meaning. When introducing themselves to the Player and the tragedians, Rosencrantz announces, â€Å"My name is Guildenstern, and this is Rosencrantz†¦I’m sorry – his name is Guildenstern and I’m Rosencrantz† (Stoppard 22). Their own deprivation of identity shows that the meaning in their individual lives is lost, making them into cynical, unrecognizable objects. In addition, they have lost their idiosyncrasies, creating a problem for other characters in distinguishing between the two. During a discussion about the King giving them an equal amount of money, Guildenstern exclaims that the king â€Å"wouldn’t discriminate between [them]† (Stoppard 104). To the King, Ros and Guil are simply two objects that are willing to assist in any way possible; to him, there is no point in getting to know them individually. The King’s lack of differentiation between the two shows that Ros and Guil have lost a deeper meaning to the King, leading to the bereavement of identity. The ambiguous identities of Rosencrantz and Guildenstern obliged their characters to embody no purpose, inflicting the idea of existentialism. Ros and Guil’s doomful deaths were caused by their nonexistent individuality. The pair’s past also lead them through an existential drift; without meaning in their past, the pair still have nothing to go on. The uncertainty of Rosencrantz and Guildenstern’s past supplements the idea of existentialism by making the play enigmatic. While walking along the path to Elsinore Castle, Ros and Guil attempt to comprehend what they are doing before making the expedition to the estate; Guil asks Ros, â€Å"What’s the first thing you remember? † and Ros replies, â€Å"Oh, let’s see†¦the first thing that comes into my head, you mean?†¦ Ah. It’s no good, it’s gone† (Stoppard 16). Ros and Guil are not able to recollect past events due to the fact that the prior matters adhered no meaning. Even when Ros and Guil are dying, they cannot recall what they have done to deserve this with Ros crying, â€Å"We’ve done nothing wrong! We didn’t harm anyone. Did we? † and Guil replies â€Å"I canâ₠¬â„¢t remember† (Stoppard 125). At their dying second, Ros and Guil are still unable to fathom what they have or have not done. Their past events are proven to be meaningless, leading them to an existential wandering containing no answers. Also through the use of anti-heroes, Stoppard made Rosencrantz and Guildenstern useless individuals who could not carry out a duty without the succor of one another. An anti-hero, in some cases, considers his or herself to be incapable of completing tasks while being corrupt, sullen, and disaffected. Rosencrantz and Guildenstern entrust each other to get through all dilemmas and yet they still become confused. When deciding what their next undertaking shall be, Guil asks Ros, â€Å"What are we going to do now? and Ros replies, â€Å"I don’t know. What do you want to do? † (Stoppard 17). Using a popular decision-making device, Ros and Guil reveal that they do not have the confidence to decide what to do and to execute the decision. Confidence is an indicator of optimism, responsibility, and initiative; Ros and Guil occupy none of these positive attributes, giving manifestation of anti-heroes. Also, Ros and Guil count on the King’s letter to get through the peregr ination, with Guil saying, â€Å"Everything is explained in the letter. We count on that† (Stoppard 105). Ros and Guil refer to the letter whenever a predicament arises, urging them to resolve the issue. With the letter epitomizing their fate, it is what they count on the most. The pair fails to envisage that one another and the letter were the ultimate factors that lead to their demise. Rosencrantz and Guildenstern live up to the idea of anti-heroes in existentialism by being each other’s hopeless backbones and depending on the letter, which leads them to their fateful deaths. Through the utilization of vacillating identities, unforeseeable knowledge of the past, and anti-heroes, existentialism augmented Rosencrantz and Guildenstern’s ultimate kismet – their anticipated deaths. Tom Stoppard leads Ros and Guil through an obscure existence that turns out to encompass nothing. With this, the reader might ask, â€Å"What is life without purpose? † – And one can say that it is certainly no life at all.

Examine Freud’s View of Religious Belief. Essay

Sigmund Freud was born in 1856; he lived most of his life in Vienna. His family were Jewish so was brought in a religious faith. Freud fled the Nazi’s in London then died the following year on the 23rd of September 1939. He was an atheist. He saw himself as â€Å"The Godless Jew†. He rejected both America and Religion. Freud had a Neurotic and obsessional character. Freud’s view on religious belief was a form of neurotic illness. Freud believed that religious activities bear a striking resemblance to the activities of a neurotic person. Neurotic conditions such as OCD repeat actions which. Primal Horde Theory, Freud’s principle contribution was the idea of the murder of the primitive horde â€Å"one day, the brothers who have been driven out, came together killed and devoured their father and so made an end to the patriarchal horde. The leader was killed out of jealously, as he was taking all the women. In guilt for the murder of their father figure they put up a Totem, symbol or animal which is believed that their spirit is inside in place of their father figure. Guilt was eventually paid of by praying or sacrificing to them Totem. Over millions of years the Totem becomes God, guilt then passed. The Totem is seen as sacred and must be protected. After a year the animal believed to be the Totem could be killed then eaten. The Oedipus complex, Freud believed that everyone suffered a dramatic trauma which was the Oedipus complex. This is when a boy at the age of six would have sexual desires for his mother and wants to kill his father, in jealousy. The suckling child was used to having its mother’s attention, where the libido is transferred

Business Project Managing And Assignments Management Essay

Business Project Managing And Assignments Management Essay Introduction Before one can tackle the question at hand, i.e. the decisions that a project manager has to make in order to create a cohesive and productive environment for his project team, one must first be familiar with the basics of project management. Project management is a wide area which has gained relatively greater importance in the last three decades. Managers began to realize that project management techniques and abilities were central to the success or failure of projects and thus a great deal of research and literature was published on the factors that affect and influence project management techniques (Maylor, 2005). Needless to say, project management is an area of study that requires a great deal of study because of the number of variables associated with it. This paper will thus start off by giving a brief overview of project management in a bid to first establish that the environment in which the project team feels motivated can in fact determine the success or fa ilure of a project and then move on to critically analyze different ways in which a project manager can improve this environment per se. Business Project Management (1)Various texts have defined a project differently, one could informally see a project as a bid to accomplish a given objective through a set of interlinked tasks using a given amount of resources. It could be something as simple as planning a wedding or a more complex task like building a new house. More formally, a project can be defined as, â€Å"A complex, non-routine, one-time effort limited by time, budget, resources, and performance specifications designed to meet customer needs (Allan 2004, p.12).† From this formal definition we can deduce some main attributes of projects such as the fact that a project has an established objective, a defined life span, has specific time, cost and performance requirements and requires across-the-organization participation. The main attributes of a project are not only ess ential for planning and implementing the project but ultimately, the success or failure of a project is judged on how well it has adhered to these essential attributes. Basically one has to see how well a project meets customer requirements and whether it has been able to do it within the time, cost and performance requirements that had been initially established. As mentioned earlier, projects can comprise large complex assignments or small tasks spanning only a few days. For practical purposes, one must also be familiar with the prevailing types of organizational structures in order to better understand the various ways in which impending projects are tackled by various organizations. The first kind can be labeled as the functional organizational structure. Different segments of the project are delegated to respective functional units of the organization and coordination is maintained through normal communication channels. Such a structure allows for flexibility, in-depth expertis e and easy post-project transition for team members. At the same time however, there is poor integration, a lack of focus and more importantly a lack of ownership for the success or failure of particular tasks. Then there is the dedicated project team structure. It is normally implemented by projectized organizations that are mainly dependent on one time projects to conduct the bulk of their business. In this system, each task or assignment is treated as a distinct project and a group of employees is put into a project team and handed the sole responsibility of completing that particular project (Burke 2003, p.89). The system is fast, simple, cohesive and allows for cross-functional integration from different departments. On the downside, it proves expensive, leads to internal strife between team members and there arises a problem of post-project transition for the employees. Thirdly, there is the matrix structure. It’s a hybrid organizational structure and seeks to combine t he best attributes of the two structures formerly discussed. Basically, there are two chains of command and project participants report simultaneously to both functional and project managers. The matrix structure achieves a greater integration of expertise and project requirements. There are three sub-types of the matrix organizational structure. In the weak-form matrix, the authority of the functional manager predominates and the project manager only has indirect authority. In the balanced form matrix, the project manager sets the overall plan and the functional manager determines how work is to be done.

The Long Walk Home Movie Review Example | Topics and Well Written Essays - 1000 words

The Long Walk Home - Movie Review Example Odessa makes a very courageous decision to go public with her desire and hope for a more just society and equality for her people. On the other hand, in the beginning of the movie, Miriam is not really even aware of racism. Miriam has lived her private white life not really understanding or even caring about what is happening around her in the public area. She is so blind to the fact that racism could invade her private life that she sends her daughter with the black maid to the "white" park, resulting in Odessa's expulsion from that park. Before the bus boycott starts, Miriam is worry about whether Odessa will come to her house to clean the house. When Odessa is unable to be on time for work or not to come to her house, Miriam starts to feel some personal consequences of racism because her house cleaning expectations were not being met. After she starts driving into Odessa's world, and sees how different life is beyond her community, she starts to change from a very private person who just wants her house cleaned to a person with moral spirit. As a result, Miriam makes the brave decision to break out of her very private "white" community and become a public figure in order to stand up against racism. She against her husband and drives into Odessa's neighborhood to pick her up and eventually begins a carpool to drive Odessa's neighbors as well. By her actions, she displays her hope in a racially equal world with more justice for the black people. This story stands as an example how small gestures can have a great impact on society. Much can be accomplished when the people, white and black both, work together to effect change. This was the basis of the Civil Rights Movement in the United States. As a matter of fact, it is possible for us to replicate their success stories in our present world in order to make it more just and humane. At first, we need to overcome the hold of prevailing negative ideologies, prejudices and stereotyping. People often tend to think that there exist a strict dichotomy between personal and public life. However, in reality, both are not only intertwined but also interrelated. Psychologically speaking, what happens in our personal life could have certain effects in our public life as well and vice versa. When we look at history, there are ample of examples that prove that when somebody crosses the boundaries of his/her personal world in order to make changes in the very world in which s/he lives, nothing could prevent the triumph that desire. Remember, when Copernicus told that the sun rounds the earth and not the other way, nobody else was there to stand for the truth. But, the truth is that truth could stand for itself. The lives of great leaders such as Luther King, Mandela, and Gandhi are the concrete exemplification of this fact. When they faced challenges in their personal life, t hey did not quietly withdraw from the scene, but, approached the world in order to make it a better place. When we see injustice of any sort around us, it is our duty to say 'Enough is Enough'. A big 'NO' can change the world a lot. "The Long Walk Home' which too presents the picture of the

Reading Response Review Essay Example | Topics and Well Written Essays - 750 words

Reading Response Review - Essay Example It implies that, the society has been bred on a certain notion that has placed the woman in a precarious situation over time, generation after generation in the course of the existence of various societies. As a societal issue, it means that it is not an issue that just sprang up yesterday, it has had to be incorporated into the culture of every society that has been looked at by the authors. It is worthwhile to note that these authors have looked at the themes of the woman, not from one place, but from different places in the world. An indication that the issue at hand is not a local but a global issue. Their representation of the issues that they have examined is unique for each one of them. Hence, they have brought about varying dimensions from which the issues can be looked at. Meaning that, if the issues are a problem that plagues society, then their solutions are diverse and far reaching. They can be solved from varying starting points and lead to one result, the liberation of the woman and an attainment of equality for the girl child. In the first reading, the woman is presented in a traditional aspect where she was viewed as an object of wealth. The reason behind men acquiring more than one wife. The view that the woman is seen as an object is well illustrated by Shinde (1994) when he relates the number of women driven out of their homes to that of men. What he tries to illustrate is that the woman is treated as the weaker species, and objectified as something that can be picked up and thrown away at any time. In addition, in reading two, the theme is still on the woman but a different perspective. That on the exploitation of women. Due to the prevailing economic conditions, the woman is the major bearer of this burden. The bearer in that she is again objectified as being an object whose role is to use her body in prostitution in order to overcome these harsh economic conditions. In reading three, the author adds on the theme of women being

Intro to Relat Dbase Mgt Syst week1 - Essay Example These include entities such as students, lecturers, courses, lecture halls, faculties and perhaps dormitories. For this project the key entities under consideration are the students, instructors, and courses. Therefore, it is logical that the first tables to be identified be Students, Instructors, and Courses tables. These are the tables in the 1st Normal Form. These key tables contain attributes that describe the entities they represent. However, the design follows two more tables that do not represent any key attributes that are initially identified. Relative Database Design makes use of relationships that are implemented using foreign keys that originate from parent tables. This process; therefore, proves challenging to implement while still exercising referential integrity. The two extra tables make the design practical since separation of the key entities is paramount (Churcher, 2012). Modification of a key entity does not affect the other key entities. These two tables are Students Allocation table and Instructor Allocation tables. Their attributes contain foreign keys for Students and Instructor tables, and they represent the action of ‘allocating’, which becomes

Organisational Culture and Leadership Essay Example | Topics and Well Written Essays - 1000 words

Organisational Culture and Leadership - Essay Example The definition of leadership is founded on the possession of a distinctive skill to influence people towards attaining set goals and objectives (Tsai, 2011). Since each organization has its own culture that governs it, the result is that there is no universally acceptable leadership style or leader. However, it is believed that provided a leadership takes into consideration the culture within the organization, the results will be great (Tsai, 2011). The first dominant framework on leadership was the Trait Theory or the â€Å"Great Men† Theory which was proposed in the early twentieth century. The theory considers â€Å"personality, social, physical or intellectual traits to differentiate leaders from non-leaders† (Shoup, 2005, p.2). This theory ascribes conventional qualities like ambition and energy, honesty and integrity, self-confidence, intelligence, and knowledge to leaders and holds that leaders are born, not made. Mid-twentieth century saw the rise of the Behavio urist school of leadership which emphasized on the actions and dominant behavior of the leaders and highlighted the leaders’ behavior on the job, use of authority and task-relationship orientation. Later, scholars such as Fred Fiedler realized that a leader must match his/her situation and leadership style should vary depending on the situation and context. This gave way to the third phase of leadership studies, known as the Contingency school, which focussed on job constitution, leader-member association, and power position.

Carry out a critical evaluation of online communities. It is important Essay

Carry out a critical evaluation of online communities. It is important that you carry this out from a business point of view, rather than from a technical. Disc - Essay Example The work of Rheingold has been instrumental in establishing ways in which others define an online community. He argues that virtual communities are social aggregations that emerge from the Internet when enough people carry on a discussion long enough to form personal relationships. This view remains recognizable in what Preece calls the e-commerce perspective of online communities. The early arguments for regarding virtual communities as a marketing tool took a Spartan view of what constitutes a community. Hagel and Armstrong contend that the community integrates content and communication in a computer mediated space. They put an emphasis on member-generated content; a perspective that may have influenced views that ‘any chat or bulletin board’ is regarded as a community by businesses. The development of an economic perspective to online communities may be frowned upon by some, but there has been a surge of interest from businesses eager to gain advantage from building r elationships with customers. The range of business communities now seen on the Web further complicates the definition of an online community. If it is more than a bulletin board, then the boundaries of the shared space and the nature of the interaction have to be identified. In an example of an embedded business community, Preece examines Rei.com. Rei.com has a link from its homepage to its community page. The Lonely Planet community is more embedded in that it has no separation between community’s space and sales space. Jones [14] argues that information exchange is not a sufficiency for a community. This paper takes the perspective that the virtual space of the website constitutes the shared space of Lonely Planet’s community. These accords with the view that the business community is more than the interchange of information between customers, that information interchange is in itself insufficient to form a community and that the company itself draws no borders but

Childhood Obesity Research Paper Example | Topics and Well Written Essays - 1000 words

Childhood Obesity - Research Paper Example It is believed that having an overweight parent doubles the risk of childhood obesity while obesity in both parents increases the risk of child obesity further. Socio-economic status of the family increases the child obesity risks further due to the behaviors and lifestyles involved (Perry et.al, 2012). With the rising prevalence of child obesity of the age of 9 years across the globe, it is important for researchers to understand all underlying pathways which may be the cause of the child obesity. The study also aims at determining the correlation that exists between the family socio-economic status, parental weight status and childhood obesity for children at the age of 9. Sampling method is the statistical method used in this research. In this method, the sample size was obtained from the study group randomly. Experimental method was used to obtain the required data. The sampling method was used prior to the research where the researchers used it to obtain the sample size for use while the experimental method was used in carrying out the actual survey. STATA Software is the statistical tool used in the statistical analysis. A study sample of 8,568 nine year children growing up in Ireland was used. Initially 1,105 primary schools out of 3200 were selected at random by the use of the sampling method. A random sample of 8,568 children was then obtained from the selected schools. ... The experimental method was used in the collection of the data from the sampled size in order to obtain all indicators of obesity in children (Perry et.al, 2012). Descriptive or parametric method of statistical analysis was used in the research. This type of statistical analysis helped the researchers to obtain the required data which is through the description of the observed data. This type of statistical analysis helped the researchers come up with numerical data of weights to determine the obesity indicators. The statistical methods used in the research are not that tiresome and are appropriate for this kind of study, and this is another reason as to why the researchers chose them. These statistical methods are also accurate in terms of the data obtained, and the use of them in research will see to a valid research findings and results. STATA is the statistical tool which has been employed in this study. In this tool, the probability weights were applied using the survey data com mand in order to account for complex survey design. The researchers chose this the descriptive or parametric method as it helps in the summarization of a sample data. The method also sets descriptive coefficients of the given data which are then used in summarizing the numerical data obtained. The data in this case is numerical since the researchers obtained numerical figures on the risk factor indicators of obesity in children. The tool used also helped the researchers to obtain the social demographic variables required for the study, helped them to perform unadjusted multinomial logistic regression which would then be used to determine the risk of childhood overweight compared to their family’s

The Criminal Justice System Essay Example | Topics and Well Written Essays - 1000 words

The Criminal Justice System - Essay Example Two main models that are used to determine which acts are crimes by society are the consensus model and the conflict model (Farmer 2008). According to the former, criminal behaviour is any act that is in conflict with the beliefs and values of the whole society. This model holds the assumption that as diverse as people and communities are, they can have similar morals. On its part, the conflict model holds that criminal law is determined by those people who hold social, political, and economic power within a given community. One of the theories that apply to crime is the rational choice theory. Also called the decision theory, this theory suggests that humans commit crimes because they serve the interests of the actors or rather bring more benefit as opposed to harm to them. This theory is based on the assumption that the criminal commits crime because they experience a constraint in choice. In this respect, the theory argues that to deter crime effectively, the cost of crime should be set so high that every reasonable person will shun it. The Government Structure As It Applies To the Criminal Justice System The criminal justice system comprises a collection of local, state and federal (public) agencies that are dedicated to dealing with crime (Randolph, 2005). In many cases, the decision of one agency affects the decisions of other agencies in matters related to crime.

The variable I am going to change will be the temperature Essay Example for Free

The variable I am going to change will be the temperature Essay The aim of my experiment is to investigate how the resistance of a wire is Affected by the length of the wire. I will be investigating by using three types of wire Thin, Thick and finally an even thicker wire then second time around. I will be also recording my results by taking down what the volt meter displays and what the Ammeter displays. I will be recording the results for each wire and also I will be increasing the wires thickness after I measure 10cm of length each time having taken down the results. Apparatus: Meter Ruler- Safety Goggles- Cell- Wire- Crocodile Clips- Ammeter- A Voltmeter- V Plan For the following experiment my plan will be to firstly wire up all the appliances to create a circuit then I will predict whether the resistance increases or whether it does not increase while the wire increases. I will carry out the experiment increasing the length of the wire by 10cm each time I will then take down the results of the voltage, current. To measure the voltage I will use a Voltmeter to measure the Voltage, to measure the length of the wire I will use a meter ruler and finally to measure the current I will use a Amp meter. After gaining these results I will work out the resistance using this formula: Resistance=Voltage/Current Having gaining the results I will write them up in a table from which I will plot the graph to support my results Then after drawing the graphs I will come to my conclusion, in my conclusion I will conclude what happened in the experiment and I will say whether my prediction is right. I will then come on to the evaluation of my experiment. Prediction My prediction is as the Length of the wire increase by 10cm the resistance will get affected making it to increase. The factors which may affect my experiment are firstly the cell(Battery) which may ran out or cause a defect, The voltmeter or ammeter may show the wrong Voltage or current and there also could be a wrong connection being made connecting the circuits. There also could be a user fault and they may measure the wrong length of wire. The factors which need to be controlled are to firstly to get a good working battery and them some healthy working wires. You need to make sure u connect the circuit correctly and also you need to make sure you measure the correct length each time. I will also keep the same temperature to make sure the experiment is even I will do this by using a thermometer to make sure the temperature is constant. I will be using Room temperature. Work Done By- SaNjE Balendra Table of results (Thin Wire) Length Voltage Current Resistance Here is the table of results for my second experiment in which I used a thick wire Table of results (2nd Thicker Wire) Length Voltage Current Resistance Here is the table of results for third and final experiment Work Done By- SaNjE Balendra Conclusion Having done my experiment I have come to my conclusion. In my experiment I have found out that as the length of the wire increases the resistance increases. This is because as the length of the wire increases it causes the current and voltage to increase which means the resistance increases as well resistance is equal to voltage divided by current. The resistance increases because there is more sufficient surface area which means the can atoms to collide, when the thickness increases it causes the resistance to decrease as there is a lot of surface area so there will be less collision. Evaluation The experiment proved to be a success and it went very well although it could be improved by trying other lengths, different voltages but also a different type of wire to be able to compare the resistance difference this would make a more interesting experiment. I feel overall my results were quite precise. You can see my results were accurate looking at all 3 of my graphs, which shows a straight line through most of the points apart from one or two which are on the line or not very apart from the line. The 2 points on the (thin wire) which was not close to the line was a Anomaly but it did not effect the gradient in the graph. In my experiment the places I think I made the most errors in the experiment was measuring the length of the wire as it was hard to measure the wire keeping it straight and then holding a meter wire to measure it. I can improve on how to measure the wire by using more than one person to either help me or do the experiment with me, I can also improve by being sensible and being focused on my work and on what am doing.

The Chrysalids Essay Example for Free

The Chrysalids Essay Despite what many might think, It is a clear fact that The Chrysalids has been written, read and acknowledged as a warning for today’s society in many ways as I will elaborate more within the following paragraph such as; different types of racism still in our society, we still have this fear that god might be sending us a message through actions like disasters and This book is well known across hundreds of nations all over the world. Chrysalid has been around for several centuries and has a very important meaning in the lives of many. It would be safe to assume that this specific piece of Wyndham’s work is going to be around for a long time and have an enormous impact on the lives of many people. If a person or community fears change and diversity in my opinion they are refraining themselves from a better tomorrow, instead of creating a convergence to create and work towards a better future. In the chrysalids the Waknukian community is inhumane to any deviation by showing inflecting rejection and degradation, in simple terms the waknukians are racist. In the Chrysalids, by john Wyndham, the people of the frontier community are those who discriminate against those who are different in any way both physically and mentally, this act of discrimination has done nothing but foster and nurture a society that is cruel and inhumane. They think anything different is blaspheme, which is sent by the devil to misguide them into another tribulation. I think even people in today’s society still act in this way, maybe not to this extreme or obviousness but to an extent. For example, when someone is overlooked for a job because of the color of their skin, nationality or their appearance, it might not evident or they might not be straight forward

Advantages And Disadvantages Of Hospitality Industry Tourism Essay

Advantages And Disadvantages Of Hospitality Industry Tourism Essay Introduction Currently, the subject hospitality management is being offered by various colleges and universities all around the world. Students and graduates of hospitality management are becoming more and more in demand in hospitality industries all around the world. Hospitality management is the academic study of the hospitality industry. Hospitality courses prepare students to face the challenges of the corporate world. Hospitality management courses also provide all the training for the students to cope with the workloads of the hospitality industry. Other than that, these hospitality management courses also prepare students with leadership skills and qualities so that students have the right kind of qualities and attitude to cope in the corporate world later on. Hospitality management can be divided into various different disciplines such as culinary arts, hotel management, tourism management etc. Each different branch of this course prepares student and graduates to face the different challenges in different field of the hospitality industry. As hospitality grows into becoming one of the most important economic sectors in the world, more and more graduates of hospitality management is being demanded in to this fields. What is hospitality industry? Why is it becoming an important in the economic sector around the world? The dictionary definition of hospitality is the friendly reception and treatment of strangers. The hospitality industry consists of businesses and institutions involving food and beverage, tourism and all kinds of lodging establishments. The friendly reception and treatment of guests is the responsibility of the people who work in the hospitality industry. 1.1.1 According to statistics, Lodging is the seventh largest industry in the United States of America and food and beverage service is the fourth largest. Twenty-three cents of every dollar spent by a U.S. traveler are spent in a hotel and twenty-one cents are spent in a food and beverage establishment. This shows the importance of hospitality industry to a countrys economy. Almost half of every penny spent by a traveler is contributed to two of the largest establishment in hospitality industry. 1.2 Since we all know that there are very good opportunities and bright future working in the hospitality industry, but what are the advantages and disadvantages of working in the hospitality industry? 1.2.1 Servicing in the hospitality industry is subjected to personal interest. To people who are interested in social skills and interpersonal communication skills, they may find hospitality industry an interesting career field. This is because in hospitality industry, we are dealing with people, servicing people where almost all of them are strangers. A great deal of interpersonal communication skills are involved in this industry. This may be of an advantage or a disadvantage as not all people are born with fluency in interpersonal communication skills though it can be acquired through a great deal of training. 1.3 A career in the hospitality industry can provide one with responsibility, advancement, diversity and personal satisfaction. A career in the hospitality requires a great deal of responsibility due to the high amount of workload. Advancement in hospitality industry is so when opportunities are provided for employees to be promoted to a higher post in the industry. 1.3.1 As said earlier, hospitality industry is an industry which involves serving guests and customers who are strangers most of the time. This is meant by diversity in hospitality industry. Each day, employees of the hospitality industry face people who come from different part of the world; this proves the diversity of the hospitality industry. Other than that, people who are interested and have acquired skills such as interpersonal communication skills, they might achieve personal satisfaction working in this industry. 1.4 The hospitality industry is full of opportunities for great advancement provided one puts in a great deal of hard work. Hospitality industry can be divided into so many fields and branches. As stated earlier, hospitality industry is referred to as one of the fastest growing economic sector around the world. In hospitality industry, there are countless job opportunities offered to employees. From waiter at a restaurant to Chief Executive Officer (CEO) at large hotels, all of these jobs are classified under the hospitality line. Moreover, the hospitality industries nowadays are facing a serious problem on the lacking of human resources. More and more employees are needed in the hospitality industry. If one were to graduate with a degree in hospitality management subject, he or she will never have to worry about not getting a good job with good pay. 1.5 However, working in the hospitality industry brings some disadvantages too. Hospitality industry is known for its extended, odd and uncertain hours of operation. Most hospitality premises have to operate 24 hours per day, if any colleagues are on leave, others might have to extend their working time or work load in order to compensate the efficiency of work. For instance, ski or water sports resorts operate seasonally based on weather conditions. Some restaurants operate only during breakfast or lunch hours. Employees working under these sectors of the hospitality management have to cope themselves with the irregular working time. However, employees are human too; they need adequate rest time in order to maintain high work efficiency. There are cases where employees work over time just to compensate the work load of absent workers, they fell sick or ill. 1.6 Hospitality industry is also known for its tremendous workload. Employees working under the hospitality industry have to put in a great deal of hard work in order to cope up with the workload in the hospitality industry. However, if an employee graduates from any hospitality management sector, he or she will be trained to handle the workload that they might face when working in the corporate world later on. 1.7 Working under the hospitality industry allows one to gain a lot of skills which cannot be acquired through studying. Employees who worked under the hospitality industry have found to possess of effective communication skills, innovation, creativity, leadership qualities, critical thinking skills, decision making skills, negotiation and conflict management. If you consider the working routine and responsibility of one who work under the hospitality industry, you will find that these skills are relatively important for employees in order to serve the guests or customers well. From a front desk representative to a general manger in a hotel, they must at least possess of a few of the skills from the list above. Especially for those who work in the management level, they must possess of all the skills mentioned above so that he or she could lead the team well and also be a role model to his or her staff. 1.7.1 Working under the hospitality industry also enables employees to acquire a very important skill teamwork. Teamwork is one of the most well regarded qualities in the corporate world. In the hospitality industry, staff of the whole operation work as a team and this requires a great deal of teamwork. When employees and employers practice good teamwork and work together to handle big cases, the problem seems to be solved efficiently and effectively. CONCLUSION Hospitality industry is a fast growing sector and is economically important to the world. Tourism which is one of the fields in the hospitality industry shrinks the world by providing a more in-depth look at the enormity and complexity of international travel. Working in the hospitality industry has both advantages and disadvantages and is subjected to peoples point of view. It also depends on ones interest. As said earlier, people who have good interpersonal communication skills will find working in the hospitality industry an easy feat but to those who does not possess of good interpersonal communication skills, they would not like it in the hospitality industry. Question 2: Find out the factors affecting travel and tourism. Explain in detail. Introduction Travel and tourism is a very common term when it comes under hospitality management. At least 20 years ago, travelling is considered as a big deal to most people but now with the aid of modern transportation, travelling seemed to be an easy feat for everyone. Nowadays, with major airlines companies offering cheap fares and giving out various promotions, everyone can just travel to the destination of their choice at a relatively low price. This has indirectly affected the business of most tourism agency. More and more people can afford to travel to any destination of their choice without having to burn a hole in their pockets anymore. The government in Malaysia has also come out with various efforts or ideas to promote travel and tourism in the country. Travel and tourism is a high profitable sector to the countrys economy. The Malaysian government is putting great effort into making the country a tourism country. The annual Matta Fair is organized by government bodies to promote tourism in the country as well as attracting tourists from other countries. Other than that, the government also has promoted Malaysia in many of the international expos and has greatly raised the name of Malaysia to the world. Since travel and tourism is made such an easy feat for everyone nowadays, there are still some barriers that stop people from travelling or other factors that cause people to travel to that particular place regularly. Actually what are the factors that affect travel and tourism? What is travel and tourism? According to the World Travel Organization (WTO), travel and tourism is regarded as the activities of persons travelling and staying in places outside their usual environment for not more than one consecutive year for leisure, business and other purpose. Therefore, people who are considered travelers or tourists are those who are away from their normal place or residence for a period of up to one year in which they will return home after that, taking part in activities that would normally be associated with leisure and tourism and on a visit that is temporary and short term. 2.1. Determinants are those factors that influence one individuals decision-making process. In short, determinants are the factors affecting ones decision whether to travel or not. Determinants can be further subdivided onto two categories which are personal factors that influenced the tourist and external factors that influenced the tourist. 2.1.1 Personal determinants are one of the factors affecting tourists decision making. Personal determinants can be divided into four categories: Circumstances of the tourist such as the health, disposable income/savings, leisure time, work commitments and family commitments. Knowledge of tourist regarding the destination, availability of various tourist products and prices differences among competitive tourist products. Attitude and perception of the destination, tourism organization, political views, particular country and cultures, modes of travel, how advance to plan and book a trip and what constitutes value for money. Experience of types of holidays, different destinations, products offered among competitive tourism organizations, taking trips with particular individuals or groups and attempting to find discounted prices. 2.1.2 When the personal determinants are taken as whole for the entire population, it would represent a market opportunity for the tourism industry. For example, with the growing affluence of the workforce and pressure in the workplace, many people would look forward to a long weekend to take a short break or vacation. The need for tourists to take a short break from work is to stimulate and rejuvenate their energy. 2.1.3 Situational factors such as time, money, health or marketing influence can intervene, as a facilitator or as an inhibitor, in making travel decision. Tourists decisions are important as it directly affects the travel and tourism. Belk (1975) identified five types of situational variables which will affect tourist behavior and decision made: Physical surrounding includes weather, geographical location, dà ©cor, sounds, lights, aromas, tangible signs and display of products, and other materials. The sunny weather can be considered as part of the destinations physical surrounding. Social surrounding includes other people and their characteristics, roles, and interactions. The social network can provide information and can act as influencer in a choice for a particular travel destination. Crowding is another situational variable, where people from crowded cities may seek isolated places to spend their holiday for a rest and to be alone for a while. Temporal perspective includes the time period, time constraints, and elapsed or expected time. The time situation is important in tourism since many holidays are limited by duration of time. For example, holidays can only be taken during school holiday or during certain says when you go on an annual leave. Tourists also prefer to go for a holiday after a time elapsed since the last holiday travel. Task definition includes the orientation, intent role, or frame of a person where certain situational may become relevant. For example, one would decide on certain criteria to go for a vacation during different time period. Antecedent states is where a situation would shape the perception, evaluation, and acceptance of the current condition, such as a person receiving a bonus, may suddenly decide to go for holiday on a STAR cruise. 2.1.4 Social and cultural influences are other factor that affects the travel and tourism. Most of the social and cultural structures are pervasive and intangible in nature. However, most tourists are unaware of the influences of these structures, even if the structures are actually embedded in their travel decision making. One of the major social influences are groups including family members and relatives. Reference group can be defines as a collection of people that an individual use as a standard for his or her attitudes, beliefs, values and behavior development. For example, since many officemates will be spending their holidays in China, one may be aspire to join the group by deciding to go along to the holiday in China. Culture can be considered as a broad, impersonal reference group consisting of the knowledge, behaviors, customs, and techniques that are socially acquired or learned by an individual. It includes beliefs, values, norms, signs, habits and non-normative behavior. Thus, culture can influence the way an individual behaves as a consumer or as a tourist. For example, one of the promotional themes to promote Malaysia as a tourist destination is to exhibit Malaysia as a melting pot of various cultures that are found in Asia. Cultures also exist within overall culture and are known as subcultures. Those subcultures are groups based on region, race, language, religion, age, social class or other factors. The island of Bali in Indonesia has been prominently promoted as a cultural destination, based on religion. Social class is another example of subculture. Social class is a product of division in society on the basis of status and prestige. Education, occupation, wealth and income are some of the basis used to explain the belonging of one social class. Some tourist destinations tend to appeal to certain groups of social class of people. For example, the French Riviera is favored among the higher social class people. Places like Langkawi Island may attract people from all social classes, but people may differentiate classes once they arrive on the island by staying at different kinds of hotels categories. In some society in Indonesia, travelling abroad is considered as a social status and sometimes the connotation of Has Been Abroad or HBA is attached to the individual. 2.2 Apart from personal determinants that we have discussed earlier, there are also some external determinants that may affect consumer travel decision making. Some of external determinants are: 1. Views from friends and relatives 2. Marketing activities in the tourism industry 3. The influence from the media 4. National-level politics and factors like economy, social and technology 5. International-level politics and factors like economy, social and technology Most of these external determinants can be further subdivided into sub-factors: Political sub-factors: Government legislation and policy, like capital control restricting amount of money taken out of the country Immigration restrictions and visa requirements Civil disorder and terrorism Taxation policy, for example, airport tax, exit fees Media sub-factors Travel channel Holiday features reported on television, in newspaper, magazines and guidebooks. Non-travel channel news reported in national Geographic programs and in news programs Marketing activities: Marketing activities by national tourist organization Brochures from travel agencies Special promotions by hotels and other travel operators. The extent of the personal and the external determinants influence the tourist behavior depend on factors such as tourists personality and their lifestyle. Extrovert people are more likely to take account of the external determinant such as the views from friends and relatives while the introvert people prefer to rely on their own experiences. People who watch news regularly and are very much concerned about the world affairs may be influenced by those external determinants compared to those people who are not worried or do not know of the situation of that country, may not consider this external factor. Some of these determinants can either be a catalyst or a constraint to the tourists motivation and desire to travel. For example, high disposable income is a catalyst and low disposable income is a constraint. Travel brochure with glossy and rosy picture of a resort destination would attract potential tourist to visit, in contrast to a cheap looking flyer. Conclusion Tourists do not make rational decision based on perfect information. They might not realize most of the determinants, as mentioned earlier. There are tourists who are aware of the various determinants to be considered in the decision making, but choose to ignore these determinants. People tend to use other aspect of lie such as pressure and emotion, to dictate their travel decision. Most literature in tourism marketing noted that there are relatively long periods spent in travel decision making process, like thinking about the vacation, collecting information, and evaluating the alternatives. Currently there is a growing trend in the tourist industry of the last-minute purchase: decision to travel. Working people have a high desire to go for a short trip whenever there is an opportunity to do so and are more willingly to go to a less interesting destination if it is offered at a low price.

Indian Camp and Soldiers Home Young Women as Objects Essay -- essays p

Indian Camp and Soldiers Home Young Women as Objects In Ernest Hemingway's short stories "Indian Camp" and "Soldier's Home," young women are treated as objects whose purpose is either reproduction or pleasure. They do not and cannot participate to a significant degree in the masculine sphere of experience, and when they have served their purpose, they are set aside. They do not have a voice in the narrative, and they represent complications in life that must be overcome in one way or another. While this portrayal of young women is hardly unique to Hemingway, the author uses it as a device to probe the male psyche more deeply. *Paragraph Break*"Indian Camp" opens with an all-male convoy of rowboats heading across the lake, with young Nick, his doctor father and his Uncle George off to see an "Indian lady [who is] very sick." As they disembark on the other side and follow a young Indian bearing a lantern to the camp where childbirth is taking place, the men's guiding interest is not in the mother-to-be as a person, but in her physiology as a case study. When they find her screaming in bed, Nick's father dehumanizes her by saying: "[Her] screams are not important. I don't hear them because they are not important." *Paragraph Break*Bitten by the young woman during labor pangs, Uncle George reacts instinctively: "Damn squaw bitch!" She is not seen as a co-participant with the men overseeing the birth. Instead, she is merely an object they are operating on, a "bitch" soon to whelp her pup, so to speak. The "studied control of the father and doctor as rational man" (DeFalco 30), a carefully constructed pose, stands in contrast to the young woman's inarticulate helplessness in childbirth. The likening of the docto... ...on to leave behind his hometown with its plethora of beauties underscores his view of young women as inconsequential objects of pleasure. *Paragraph Break*Both "Indian Camp" and "Soldier's Home" place young women in a secondary, objectified role. Hemingway takes this approach to focus attention on the psyches of his male protagonists, self-obsessed in their youth or war-weariness. It may not endear the author to feminist readers, but it does make for some powerful short fiction. Bibliography: 1.DeFalco, Joseph. The Hero in Hemingway's Short Stories.

Binary Oppisition Essay -- Greek, Corinthian Women

Binary Opposition In Greek tragedy there are many themes that are contrasted with each other. This is known as binary opposition, which s defined as a contrast of themes that are the opposite poles of each other. There are many conflicts in Euripides’ Medea and Bacchae: perhaps the three most conspicuous oppositions are rational versus irrational, foreigner versus natives, and stereotypical dichotomy of female and male. The first binary opposite in Euripides plays are rational versus irrational thinking, his characters are changing constantly within the plays; there are a couple of characters that stays in a rational thinking which they do not favor any side of the conflict. In Medea, Euripides showed rational thinking through the Chorus, who are married Corinthian women; they lend Medea support in time of need and gives advice as a friend and not as foe, when she would talk and act irrationally (Medea 173-82). The Chorus does agree that â€Å"[Jason] wrongs and betrays† Medea by breaking their oath of marriage (Medea 131-42; 208, MLA unit 6 info from). But they do not take it to the extreme thinking as Medea does and explains to her that if she does go through with her plans of revenge that â€Å"no city, no friend, will pity [Medea’s] pain† (Medea 657-58). The Chorus even advises her that killing her children and her enemies is wrong and just to â€Å"give up [her] plan[s]â €  (Medea 813). In the same way, Euripides’ play the Bacchae has rational and irrational thinkers, they are Cadmus the old king and Tiresias the prophet, and on the contrary of rational is the irrational thinkers who are Pentheus the current king and Dionysus the god. Cadmus and Tiresias are the only two men who stay rational throughout the play. They agree that there is ... ...ety. In Euripides play Medea, she uses the stereotype of woman to gain trust, an extra day in Corinth, and what is expected of the men and women in society. The conversation between Creon and Medea, â€Å"[he] orders [her] to go from this land,† but Medea starts to use the submissive woman on the king as to gain a day. She told the king† not to be afraid of me, Creon, I haven’t the means to do harm to men who are the rulers,† and manipulating king to let her stay one more day in Corinth because of her children to â€Å"have pity on them!† (271-356). In fact, Medea manipulates Jason by asking him to take the kids and not allowing them to be exiled out of Corinth’s. Medea uses that even gifts â€Å"persuades the gods and that gold is stronger than gold,† to trust her in giving a gift to his new bride as â€Å"[the] spirit of luck is with her†¦ [to] grow her fortune more† (947-975).

Effective Literary Elements in Emily Brontes Wuthering Heights Essay

Effective Literary Elements in Wuthering Heights      Ã‚  Ã‚   Critics analyze and examine Wuthering Heights to obtain a deeper understanding of the message that Emily Bronte wants to convey. By focusing on the different literary elements of fiction used in the novel, readers are better able to understand how the author successfully uses theme, characters, and setting to create a very controversial novel in which the reader is torn between opposite conditions of love and hate, good and evil, revenge and forgiveness in   Thrushcross Grange and Wuthering Heights. There is no doubt that the use of conflictive characters such as Catherine Earnshaw, Heathcliff, and Edgar, with their interactions in the two different settings creates an excellent background for a doomed love story.      Ã‚  Ã‚  Ã‚  Ã‚   The central theme of Wuthering Heights is a love story that challenges the established social rules in which the protagonists, Catherine and Heathcliff have lived; it is a story that survives the unfortunate choices that both lovers make and even mystically survives Catherine's death.   The protagonists fall in love despite the opposition of   Hindley Earnshaw.   Catherine's attraction for Heathcliff is so strong that she feels compelled go against her brother's wishes and the social class conventions existing at that time. However, after courting for a while, Catherine makes the tragic decision of accepting Edgar Linton's proposal for marriage. This decision brings about a conflictive situation between Heathcliff and both the Earnshaws and the Lintons. One day, Heathcliff overhears Catherine telling Nelly "It would degrade me to marry Heathcliff now" (Bronte 59). This comment enrages Heathcliff and he storms out of the house; ... ...to illustrate how humans shape their way to unhappiness by not addressing their true feelings.  Ã‚   However, in the end, young Catherine and Hareton are able to acknowledge their feelings and choose to be happy.   They finally obtain the happiness that has eluded the previous generation of these English houses - Wuthering Heights and Thrushcross Grange -   as clearly shown in the movie version directed by Peter Kosminsky.      Works Cited Bronte, Emily.   Wuthering Heights.

Aristotle and Metaphysics Essay

Introduction The study of metaphysics is a broad spectrum of comprehensive ideas that ultimately serve to discover the generalities of human thought. Without Aristotle, the concept of metaphysics would cease to exist. Taking this into consideration, it is evident that Aristotle plays a major part in the study of metaphysics and how we know it today. Therefore, he formulated the basic entities of metaphysics and constructed its foundation through his own philosophies. Also, after reviewing material presented by Socrates and Plato, Aristotle is able to develop an understanding of causes and substance and how it relates to metaphysics. Furthermore, actuality and potentiality are philosophical ideas that Aristotle discusses throughout his evolutionary thought-provoking beliefs. Through these instances, it is clear that Aristotle has an undoubtedly significant impact on the study of metaphysics and how it first originated. Aristotle and Metaphysics Since Aristotle founded the main ideas of metaphysics, we can assume that his affiliation with it is indisputably notable. By using the ideas he established, he is able to review the opinions previously held by other philosophers and challenge them. When other philosophers are told that they are wrong, they will go into grave detail to explain their opinion or idea. This ultimately delivers a substantial amount of depth in discussion and enhances the study of metaphysics as a whole. In addition to reviewing other philosophers’ ideas, Aristotle analyzes the causes and principles behind certain decision-making and the options they have to consider. He attempts to reason with why people make the choices they do and also touches upon subjects such as free will, determinism, and topics of that nature (â€Å"Aristotle’s Metaphysics†). Essentially, Aristotle is an undeniably brilliant mind who challenges others’ thoughts in order to better themselves as critical thinkers and improve the study of metaphysics. Furthermore, without a doubt, Aristotle abetted the development of metaphysics through the use of his own personal philosophies. For instance, in book Alpha, Aristotle proclaims a famous sentence that reads â€Å"All men by nature desire  to know. † He claims that we are all constantly in the pursuit of gaining intricate knowledge and applying it to our lives. Since this proclamation is originated by Aristotle himself, he decides that he is going to become very critical of other ideas. He brings out the strong and weak points within each idea in an effort to assist others with developing their own understanding of metaphysics. The purpose of Aristotle leading others to formulate their own ideas is to push them, and the rest of civilization, towards the ultimate achievement: wisdom (CITATION NEEDED). By guiding others to the best of his ability, Aristotle is considered to be a benefactor for the study of metaphysics and how it has progressed overtime. Causes and Substance Long ago, Aristotle developed an engaging idea that has been expanding for two millennia. It is the idea that true knowledge is the knowledge of ultimate causes. Since this idea confronts the common wonder of why things happen, it will ultimately benefit the study of metaphysics. Moreover, in an effort to fully understand how to attain true knowledge, Aristotle takes the liberty of organizing the types of causes into four simple kinds. The formal cause is when a decision is made because someone is abiding by a particular plan. Additionally, the final cause is when a reaction sprouts an action is done with a purpose. The material cause is when a decision is made based on the altercating components that are affecting the potential solution. Also, the efficient cause is when a decision is made in an effort to initiate change in a respective situation (CITATION NEEDED). Through these theoretical causes established by Aristotle, the idea of true knowledge is sufficiently easier to grasp. Therefore, we are greatly aided with the enduring quest of understanding metaphysics in its entirety. Actuality and Potentiality In book Theta, Aristotle discusses the difference between actuality and potentiality and relates it back to the study of how we interpret thoughts and ideas throughout metaphysics. Potentiality is considered to be the numerous amounts of options that we may or may not pursue throughout our lives. On the other hand, actuality is not our options, but rather our final outcomes. To put it into perspective, a person is born with the potential to be a professional quarterback, a chemical engineer, or anything else for that matter. However, it is not until they have become the quarterback or the engineer that they have reached actuality. (â€Å"Aristotle’s Metaphysics†). Given that the basic ideas of actuality and potentiality are considered to be lofty contributions to the general understanding of thought, it can be assumed that Aristotle’s involvement with metaphysics is undeniably momentous. Conclusion. The fundamental ideas of metaphysics were brought into the world by Aristotle himself. Also, without his basic philosophies, much of the understanding we have on metaphysics may not have been discovered. He plays a critical part in the early stages of discussion when he attempts to challenge the minds of other philosophers in an effort to further advance the study of metaphysics. Additionally, Aristotle expands on the understanding of true knowledge through the causes and substance we endure throughout our lives. Considering that actuality and potentiality are both important topics of discussion in regards to metaphysics, Aristotle portrays an immense amount of importance that is irrefutably unparalleled. All in all, Aristotle’s involvement with the origination and the forever-expanding details of metaphysics is commodiously prevalent and will forever be an influential part of our society as a whole.

New media Essay

New media has transformed the way we receive and produce content. New media such as the internet is making it easier for people to get their opinions across which creates content and allows a two-way dialogue. New media and technologies such social media networks change the way a person perceives the world. In the past decades, old style media was the only form of media used to receive content and sharing content was not as easy like it is nowadays. Internet can be easily accessed, with the transformation process still continuing it is now easy for the public to create and upload content which form discussions. Habermas’ conception of the public sphere (Scannell 2000). Habermas defined the idea of the public sphere as a social space in which all participants spoke as equals, made rational arguments, felt free to question authority and traditional political assumptions. New media is broadcasted though digital media and online sites such as Facebook and the internet. Content is shared and created through social media by uploading or publishing content such as images, videos and text. New media allows individuals to receive and share content. The rapid development of computer science leads to the emergence of brand-new type media which is transforming the world and the way how people perceive the world. Interactivity which distinguishes new media from their traditional counterparts endows them with capability to transform the mode of communication. Based on the powerful computer science and technologies, new media quickly engulf the whole world. Rather than evolving from traditional media and extending to new fields traditional media fail to reach, new media are completely another tool with totally different structure and mechanism against which they function. They make it possible to construct a three-dimension world resembling exactly what human beings actually live and give people a realistic feeling after stepping in. This capacity leads to a new mode of cultural representation, simulation. The implications are more than just to imitate and reveal true, but also include creating truth  creating a reality that cannot exist in the actual world. The interactivity closely associated with new media enables them the transform the conventional communication mode as well. The one-way information flow in traditional media changes into the two-way dialogue, then into â€Å"group discussion†. Virtual communities and social networks take shape. There, communication participants are no longer persons in conventional sense, but reduce into roles. A single person can have various roles to present in different spaces created by new media. An example of the two – way dialogue is the â€Å"BUST THE BUDGET† on the sbs site and through social media such as twitter people who attended the rally were able to connect and present their opinions to sbs. Online social networking communities are transforming the way we are experiencing television/network channel content. Social media connects people from local to global. Online communities talk everything that excites, entertains, energies or anything that creates an emotional bonding with certain kind of stuff. Social sites like Twitter and Facebook are the platforms where communities share information, ideas and insights. To conclude, media quickly to engulf the whole world. Rather than evolving from traditional media and extending to new fields traditional media fail to reach, new media are completely another tool with totally different structure and mechanism against which they function. They make it possible to construct a three-dimension world resembling exactly what human beings actually live and give people a realistic feeling after stepping in. This capacity leads to a new mode of cultural representation, simulation.

There, communication participants are no longer persons in conventional sense, but reduce into roles. A single person can have various roles to present in different spaces created by new media. Cultural representation and  communication are no longer what they used to be in face of the powerful engine. This is what â€Å"new† in â€Å"New Media† exactly means transformations.

The Nuclear Fusion Reactor Engineering Essay

Before any probes are done on reexamining suited stuffs for a atomic merger reactor, a general thought of the atomic merger itself had to be introduced. Nuclear merger is the procedure that is straight opposite of atomic fission[ 1 ]. It is a procedure that fuses two or more atomic karyon together in organizing a larger karyon. The karyon involved here are usually the isotopes of H as it is most executable to pull out energy from the merger of these atoms. This procedure releases enormous sum of energy[ 2 ]and it is believed to hold an energy denseness of three to four times greater than the energy denseness of atomic fission which itself is a million times greater of the energy denseness of chemical reactions. Besides that, atomic merger produced much lesser radioactive waste. ( 1 ) Therefore, merger is a really possible power beginnings that are both economically executable and safe. Besides that, merger fuel is renewable, abundant in nature and cheap ( 2 ) . However, to day of the month, there is non a executable operating commercial atomic merger power works. There are, nevertheless, several experimental merger reactors that are operational but they are non sustainable and therefore non executable at the minute. Inarguably, merger reactor is highly hard to construct. Fusion procedure itself is difficult to accomplish under normal fortunes. Fusion fuses 2 or more positively-charged karyon together and it is non hard to conceive of that the energy required to convey the karyon together is really big as the repulsive force force between two indistinguishable charged atoms is reciprocally relative to the square of the distance of the atoms[ 3 ]( 3 ) . In order to originate a merger procedure, it is required to heat the mixture of deuterium-deuterium ( DD ) or deuterium-tritium[ 4 ]( DT ) up to a temperature of non lower than 100 million Kelvin for the karyon to come near adequate to each other and fuse. At these temperatures, the H will be in a wholly ionised province known as plasma. ( 4 ) Presently, there are two ways to accomplish the temperature necessary for the atomic merger to take topographic point. They are, viz. , magnetic parturiency method and inertial parturiency method. Magnetic parturiency merger reactor uses magnetic and electric Fieldss to restrict the isotopes and heat them up to the needed temperature. Inertial parturiency merger reactor, on the other manus, uses optical maser beam or ion beams to heat up the plasma. ( 5 ) For the intent of this literature reappraisal, the magnetic parturiency method will be investigated as this method is considered as more dependable and hence, it is more extremely developed ( 6 ) . Among the magnetic parturiency merger experimental curates, International Thermonuclear Experimental Reactor ( ITER ) will be peculiarly investigated together with Joint European Torus ( JET ) as the back uping probe. This is because ITER is the replacement of JET and ITER is presently the universes ‘ largest tokamak[ 5 ]atomic merger reactor which purpose to move as a operation and prolonging magnetic parturiency merger power works bring forthing net energy of 9 times the power its consume[ 6 ]( 7 ) . This is known to be the biggest graduated table of the merger reactor so far in the universe where the merger reactor will hold a really high energy generation and sustained burn. Upon the successful demonstration/experimentation in ITER, a all-out merger reactor will be able to be con structed on a larger graduated table based on the rule of ITER and benefits the world. Therefore, it is instead relevant to look into the potency of ITER in this reappraisal as if ITER is successfully built and demonstrated, a full graduated table power station that map wholly based on atomic merger can be produced. The building of ITER is still undergoing and expected to be completed in 2019.Objectives & A ; MotivationsThe aims of this literature reappraisal are to reexamine and take different stuffs that are suited in the building of the atomic merger reactor specific for ITER based on literatures available. In constructing a atomic merger reactor, different facets will hold to be considered and investigated as the standard for constructing a atomic merger power works is non easy satisfied. These will be farther discussed in this reappraisal. Therefore, in order to fulfill the different standards and different facets, different stuffs and their belongingss will hold to be consider ed before any choice is done. The motive of this literature reappraisal is based on the feasibleness and the limitless capablenesss of a atomic merger reactor. It is expected that non-renewable resources which are chiefly natural fossil fuels such as coal, crude oil and natural gas would be depleted by 2100. The present civilisation are mostly based on oil and gas in energy coevals and production and therefore by 2100, if alternate beginnings are non sought after, so the present civilisation would fall in due to the energy deficit ( 8 ) . Nuclear merger power works, a really promising energy beginning, is being investigated by the scientists and applied scientists as one of the alternate beginnings of energy upon depletion of fossil fuels. Nuclear merger power works would non potentially let go of C dioxide ( CO2 ) as pollutant to the ambiance therefore will non be lending to planetary heating. Fusion fuels are besides abundant in nature as heavy hydrogen and tritium can be easy obtained from saltwater and Li[ 7 ]easy. If all heavy hydrogen in one liter of H2O is used to blend with tritium, the energy produced by this will be tantamount to the combustion of 340 liters of gasoline ( 9 ) . Contrary to atomic fission, atomic merger leaves minimal or none of the radioactive waste. Contrary to atomic fission as good, the atomic merger power works have no potency of meeting a meltdown[ 8 ]at all and therefore will non do black consequence to the environing environment. For all these advantages, joint attempts from developed states all round the universe are sing atomic merger power works as a possible energy providing and therefore different constructs, proposals and designs had been proposed in order to construct a functional merger reactor. Therefore, it is non difficult to conceive of that the motive of the subject â€Å" Advanced Materials for Fusion Reactors † is wholly based on the fact that merger power works would be to a great extent dependent on in the hereafter if it is succeeded been developed.Components of Nuclear Fusion Reactors2.1 IntroductionThis literature reappraisal will get down with a general debut of the constituents of a magnetic parturiency atomic merger power works and how the power works plants, so will be divided into subdivisions look intoing the major proficient challenges of some constituents inside the reactor. Upon the proficient challenges are determined, the focal point of this reappraisal will be on choosing the stuff belongingss that are suited for the job an d therefore the appropriate stuff measure uping for the peculiar belongings.Magnetic Confinement Fusion Power PlantThere are presently different methods in accomplishing the parturiency of the hot plasma magnetically. Among the most recent and widely method used is Tokamak whereby ITER itself is based on the construct of Tokamak ( 10 ) . This might be due to the fact the Tokamak is the most well-developed magnetic parturiency system at the present phase. Illustration of the magnetic parturiency merger construct Figure: Conventional Diagram of a Tokamak ( 11 ) Figure: Conventional Diagram of the Tokamak in ITER ( 12 ) Figure 1 and Figure 2 both show the conventional diagrams of how a Tokamak will look like. The vacuity vas[ 9 ]on Figure 2 will incorporate plasma and will be the topographic point where the merger reaction will take topographic point. The cover faculty will be screening the vacuity vas from the high-energy neutron and bring forthing tritium for farther merger procedure ( 13 ) . The toroidal field spiral and poloidal field spiral[ 10 ]are responsible to make a magnetic field in perpendicular and horizontal way to restrict the hot plasma and maintain the plasma off from the wall ( 14 ) . The cardinal solenoid will on the other manus bring on the current in the fuel that will ionize the H fuel organizing the plasma, heat up the plasma to about one tierce of the temperature required by merger[ 11 ]( 14 ) and besides shape the magnetic field in the divertor part ( 15 ) . The divertor maps as an ‘exhaust ‘ to pull out heat from the merger reaction every bit good as the waste m erchandise – He ( 16 ) . As mentioned earlier, the merger requires a temperature of over 150 million Kelvin, and hence, the warming produced by plasma current is deficient to heat up the plasma. Therefore, external warming[ 12 ]will be required to heat up the temperature further to the desired 100 million Kelvin. As ITER is an experimental reactor to look into the possibility of a merger reactor, hence, there are besides extended nosologies systems that are installed on the Tokamak to analyze the belongingss of the plasma and the existent perfomance of the ITER ( 18 ) . Finally, the cryostat is responsible to incorporate and back up the whole Tokamak construction. ITER will non be able fo map with the whole Tokamak system entirely. It needs external system to back up it as a functional reactor. As explained above, the plasma will be contained in a vacuity vas and therefore a vacuity system will be needed to pump air out of the vacuity vas to make a status of highly low denseness and force per unit area[ 13 ]( 19 ) . Contrary to atomic fission, atomic merger reaction will merely happen one in a clip inside the tokamak. This means that certain sum of mass of H fuel[ 14 ]is injected into the vacuity vessels one at a clip and let the merger reaction to take topographic point. Therefore, a fuelling system must be used here. Due to the fact that the force per unit area inside the vas is really low and the fuel involved is really little, the merger reaction in ITER clearly will non do any lay waste toing consequence to the environment or the reactor once the reactor goes incorrectly. As the ITER is runing on a really big graduated table, much larger compared to its old version, hence, the magnets[ 15 ]will be heated up really rapidly and therefore is required to be cooled utilizing cryogenic engineering ( 21 ) . Distant handling is besides required in the ITER as it is impossible to make any fix or maintainance in the ITER while the reactor is active ( 22 ) . Like any other power works, ITER will necessitate a chilling system that will be responsible to chill or instead extract any heat released in the procedure ( 23 ) . For ITER, the heat will be dissipated to the milieus as it is an experimental reactor that are non responsible to bring forth electricity. For a real-life reactor, the heat extracted will be used to bring forth steam to turn the turbine which will in bend generate electricity. This would be the precisely same rule as a real-life power reactor. Ultimately, a power supply is required for ITER as it is impossible to bring forth any end product power without initial input power for a merger power works. These will be the chief constituents of a merger reactor. Each constituent will subsequently be investigated seperately together with the pick of stuff for the constituent. The general working rule behind a merger reactor like ITER will be as follow: First, all drosss and air are pump out of the vacuity vass. Fusion fuel will so be allowed to come in the reactor through the fuelling system. The cardinal solenoid will so bring on current to the fuel and inonize it into plasma while heating up the plasma. Simultaneously, the toroidal field spiral and poloidal field spiral will be activated and they will bring forth magnetic gield that will steer the plasma in weaving around the vacuity vas. External warming will farther heat up the temperature of the plasma up to around 150 1000000s Kelvin. The merger procedure will so get down. High-energy neutron will be released and absorbed into the cover. The energy produced by the neutron and the merger reaction will so be absorbed by the go arounding chilling H2O which will so disperse the heat consequently. Any merchandise that are left behind will so be exitting through the divertor.Material Challenges Presented in a Nuclear Fusion ReactorThere are several challenges that had to be faced in constructing a Tokamak type merger reactor. In fact, the challenges can be largely demonstrated on constructing an experimental reactor such as ITER. First and first, the neutron released by the merger reaction has a really high energy of about 14 MeV. Even fission reaction will merely let go of neutron of energy 2 MeV. Therefore, appropriate stuffs must be selected to see such neutron flux and barrage. Such barrage on any stuff will decidedly damage the stuff and induces radiation ( 24 ) . Besides neutron irradiation, the stuff must besides subject to gamma radiation flux and impersonal atom fluxes. Though non obvious, but the nosologies system in the ITER will besides necessitate to defy such rough environment in the vacuity vass ( 18 ) . The cover wall will function multiple intents every bit good. The cover wall needs to be able to bring forth tritium when interacting with the neutron release by merger reaction to farther fuel tritium for following merger ( 25 ) . The first wall of the plasma chamber will necessitate to confront the highly high temperature plasma every bit good. Therefore, it will be subjected to electromagnetic moving ridges of high energy which chiefly are X-rays ( 2 ) and highly high heat burden. Due to extreme heat flux, there might be hazard that stuffs will be evaporated from the divertor and being deposited on the plasma confronting surface ( 26 ) . As the merger power works like ITER use magnetisms to restrict the plasma, it is besides of import to observe that the magnets used in the power works must be of high efficiency. It is suggested that the magnets use here should be ace conducting as the power consumed by a normal magnet to restrict such plasma will be really immense ( 2 ) . As the divertor is responsible to wash up the byproduct of merger, it will hold to digest high heat tonss[ 16 ]and supply the shielding for neutron barrage every bit good ( 27 ) . The cardinal solenoid and poloidal field spirals will bring on a big and fluctuating magnetic field of about 1T at the first wall and 0.2T at the cryostat wall ( 26 ) . The operation of ITER is besides the largest to day of the month which it will necessitate to keep a steady-state operation of more than 1 hr. With that in head, this will be the harshest environment that is yet to be experienced by bing stuffs. Before any choices are done, the readers of this literature reappraisal are advised that the choice of all stuffs are done based on the diaries and the studies done by the ITER forces and applied scientists and their suitableness remains to be confirmed. There are besides some company being suggested by the ITER organisations that are specializing in production of different stuffs for each constituent. Readers that are interested can look up the company. The general choice of the stuffs for cardinal constituents had already been summarised in the Table 4 of Appendix. Full design specification of ITER can besides be viewed at ( 28 ) .General Structural MaterialThe general structural stuff here is the stuff for the in-vessel constituents[ 17 ], the vacuity vass and cryostat. There is a general understanding that the structural stuffs in a merger atomic power works should non bring forth any radioactive merchandises that have a long life clip and the ephemeral radioactive merchandise on the other manus should non do unacceptable safety effects. This is to forestall the volatile radioactive merchandises that might be released into the environment in the event of accidents and to understate the consequence of high decay heat[ 18 ]. This in footings regulations out the possibility of utilizing several debasing elements for steels in ITER. These include Nb, Mo, Co and Ni ( 29 ) . For ITER, the most suited structural stuff would be unstained steel ( SS ) . The class selected here would be type 316L ( N ) -IGX[ 19 ]austenitic SS. The steel selected here had many belongingss that are first-class for the ITER constructions. Among the belongingss are equal mechanical belongingss, good opposition to corrosion, able to be welded, forged, and casted[ 20 ], industrially available can be easy manufactured, much less sensitive to radiation embrittlement ( 32 ) . The austenitic SS here is besides well-known for its extended database and acceptable radiation harm opposition. Although some lessening in ductileness might happen due to irradiation at temperature of 275-375A °C, but this is sufficient for ITER operation ( 32 ) . The austenitic SS proposed for cryostat would be 304L. Although the steel is being selected, there are certain demands for the contents of the steel that must be satisfied. For a merger reactor, activated Co ( Co ) is really important in lending radiation dosage. Therefore, the decrease of Co content in all the chromium steel steel used to 0.05 % can cut down the activation of the constituents ( 30 ) . Besides Co, Nb would bring forth durable radioisotopes that will post a job in waste direction and decommissioning. For 316L ( N ) -IG SS, Nb is present as hint component. It is of import to cut down Nb content in the steel to 0.01 % ( 30 ) . Although the stuff for shielding of the chief vacuity vass will be SS 316L ( N ) -IG, the shielding of the primary vass[ 21 ]can be done utilizing SS 30467 with 2 % B[ 22 ]and the stuff for ferromagnetic shielding[ 23 ]can be done utilizing SS 430 ( 31 ) in the vacuity vas. Besides the general construction, the stuff of nickel-based-alloy keys and bolts[ 24 ]used must be investigated here every bit good. The general stuff for cardinal and bolts would be Inconel 718 ( 30 ) . The pick of stuff here is due to the fact that Inconel 718 has high strength, stamina and weariness opposition and it is widely used in atomic industry and commercially available ( 32 ) . The expected neutron irradiation experienced by the bolt would be 0.5 dpa, under such status, the strength of Inconel 718 will increase together with a little lessening in ductileness but it will non impact the overall constituent unity over its life-time. However, the low coefficient of thermic enlargement of Inconel 718 must be taken into consideration ( 33 ) .The BlanketAs mentioned in Section 2.3, the cover is a really of import constituent in ITER. The cover will hold to fulfill the undermentioned demand: To defy the high heat burden due to its close contact with the plasma. To retrieve tritium and to engender tritium fuel for new merger reaction. To supply thermic screening to the vas. To supply screening from neutron barrage and bring forth a little sum of radioactive waste. To retrieve heat by provide sufficient cooling/heat money changers. To protect the magnet spiral from the atomic radiation. In a merger reactor like ITER, the cover system is farther divided into 2 parts, viz. the first wall as the first bed of protection, and the cover as the shielding and tritium genteelness. Most of the neutron produced by the merger will go through through the first wall and are absorbed in the cover and the shield ( 2 ) . Therefore, the cover will be responsible to capture these neutrons while pull outing their energy and besides breed new tritium to replace tritium used in the merger procedure. The heat sink besides exists here to let heat exchange to take topographic point. On the other manus, the first wall will supply screening for tritium and in the ITER, it will be the most tritium-contaminated device ( 27 ) . The first wall is besides responsible to screen the constituent behind it from the direct contact with plasma. Therefore, the first wall should be able to defy the corrosion resulted from the plasma when they are in contact with one another. Besides, for the intent of eas y care, the cover wall is modular. The full cover parametric quantity is listed in Table 1 as shown below: Table: Blanket Parameter for ITER ( 500 MW merger reactor ) ( 27 ) Beryllium ( Be ) is the first pick of stuff for the tiles of the first wall. This is because of the undermentioned belongingss: low plasma taint, ability to defy big figure of perpendicular supplanting events ( 34 ) , low radiative power losingss, good O gettering provided that heat burden is non sufficient to vaporize Be, low tritium stock list[ 25 ]( 35 ) , absence of chemical spluttering, low atomic figure, the possibility of in situ fix of the harm faculties by plasma spray, first-class neutron and energy generation. The class of Beryllium selected is S-65C VHP due to its low content of metallic dross, high neutron irradiation opposition, high thermic weariness opposition, high elevated temperature ductileness and low cycling thermic weariness ( 30 ) . However, the chief job of Be are toxicity and handiness ( 25 ) . The toxicity will non be an issue[ 26 ]here and sing the handiness, Be can ever be reprocessed upon the terminal of the life clip of the reactor for new reactor. There is available engineering and processs to manage Be at current minute and the reprocessing is executable. The existent ingestion of Be will non be much of a concern. Other than that, there is a chief concern that the brickle break of Be is noticed when it is tested under low irradiation temperature[ 27 ]( 30 ) . Such embrittlement at low temperature could take to the brickle failure of the faculties. Additional R & A ; D is needed to analyze the break mechanics of S-65C VHP. It is besides noticed that Be is merely acceptable for a low-duty rhythm machine[ 28 ]such as ITER ( 34 ) . In decision, the first wall panels and the bulk of the internal Tokamak surface will be covered by Be. Their occupation is simple, to defy and reassign the heat from the plasma t o the chilling system via heat sink. In fact, for ITER and JET, there is already a company in Finland known as DIARC-Technology Inc. that is specialised in supplying the plasma coating ( 36 ) . It is of import besides to observe that ceramic complexs such as silicon-carbide ( SiC ) fibre-reinforced SiC-matrix had been conveying to the concern of the applied scientists. Ceramic complexs are of peculiar involvement due to the fact that the degree of radiation induced here is much lower[ 29 ]than that of a metallic construction ( 2 ) . However, with the high pay-off, it comes with high hazard. The high pay-off is evidently the first-class safety of SiC due to its highly low induced radiation, whereas the high hazard is uncertainness of the SiC public presentation and belongingss when it is subjected to irradiation under high temperature ( 37 ) . Table 2 is attached naming the cardinal constituents required if the new-generation SiC is chosen to be used as the structural stuff and the nucleus stuff[ 30 ]in the power works. Several issues need to be raised before sing SiC: the cost of fiction of the complexs, the connection method, low thermic conduction under irradiation at hig h temperature, and the maximal operating temperature around the cover and the constructions of the works. SiC had been considered in assorted power works designs such as TAURO, DREAM, and AIRES-AT. However, it is non being considered as the chief structural stuff in ITER due to its unpredictable public presentation. Further R & A ; D might be required to develop SiC into a high public presentation merger power works nucleus stuff with safety advantages. Detailed plants can be referred at ( 37 ) . Table: Suggested Parameters for a SiC-based Fusion Power Plant ( 37 ) Besides the screening consequence by the first wall, cover besides act as a tritium breeder. The suited stuff here would be Li or Li compounds as it will absorb the high-energy neutron and release tritium as shown in Equation 1 and 2 below ( 2 ) . The first reaction will devour energy of 2.87 MeV but it will bring forth an extra neutron that can undergo farther reaction to engender tritium. The 2nd reaction will take to an energy production of 4.8 MeV. The enrichment of the Li in the compounds depends on the type of power reactor. Equation.Equation Among the Li compounds, Lithium zirconate ( Li2ZrO3 ) is preferred as the genteelness cover due to its good irradiation stableness, its good compatibility with steel, low tritium keeping at low temperature, and insensitiveness to wet ( 31 ) . The Li here can be enriched to 90 % to heighten the genteelness of tritium. The genteelness cover here will be in the signifier of pebbles. The proposed agreement of the breeder would be holding 2-3 breeder zones embedded in Be tiles giving the net tritium genteelness ratio of greater than 0.8 ( 31 ) . Ultimately, the dramatis personae steel can be used as the concluding shielding portion of the first wall ( 30 ) . In the design of ITER, a high thermic conduction stuff, known as heat sink, will be placed in between the armor and the chilling channels with its chief fuction being reassigning the heat fluxes and energy extracted by the first wall to the coolants, cut downing the thermic emphasiss undergone by the protecting constituent expeditiously. Therefore, for the heat sink, the Cu ( Cu ) metal would be preferred due to its high thermic conduction. The class selected here would be CuCrZr metal. However, the belongingss of CuCrZr alloy depend extremely on its thermomechanical intervention and fabrication procedure. Provided the fabrication procedure will impact the belongingss minimally, CuCrZr will hold high break stamina at high temperature. Besides CuCrZr is a weldable stuff and it is widely available in the market. Although the metal will exhibit radiation hardening, lessening in ductileness, and loss of the ability for work indurating at low neutron irradiation temperature, the public pr esentation of the metal still meets ITER ‘s standards ( 32 ) . However, this CuCrZr metal will be differ from the standard one in footings of its content. For the standard metal, the Cr contents would change from 0.4 % to 1.5 % and Zr contents would change from 0.03 % to 0.25 % , nevertheless, the metal used in ITER would utilize a much narrower scope[ 31 ]. The ground of restricting Cr in much narrower scope is to cut down the possibility of formation of harsh Cr precipitates which will affection the radiation opposition. Zr on the other manus will do hardening of metal and influences the recrystallization temperature and the ageing clip. The restriction of O in the metal to less than 0.002 % and the entire sum of drosss to less than 0.03 % is besides needed for a better embrittlement opposition ( 30 ) . Besides the stuffs for each constituent, the stuff of the articulations of heat sink to the cover faculties and to the overall construction needs to be considered every bit good. To bond the heat sink onto the armour stuffs, a procedure known as Hot Isostatic Pressing ( HIP ) is introduced ( 36 ) . HIP bonding is a type of fabricating procedure that will adhere metals together while cut downing the porousness of the metals and it will ensue in tight geometrical tolerance. The status of the HIP of the two stuffs is furthered explain in ( 32 ) and ( 31 ) . In fact, the articulations of Be/Cu and Cu/SS had been successfully tested under heat flux up to 12 MW/m2 under 4500 rhythms ( 31 ) . In UK, there is an technology company known as AMEC worked with the bonding of the hot sink to the Be foremost wall. Detailss for HIP fall ining engineerings can be viewed at ( 31 ) , ( 38 ) and ( 39 ) . Figure: Blanket Flexible Support Attachment ( 32 ) There is another stuff concern here for the covers attachment. As shown in Figure 3, it is necessary to attach the cover to the vacuity vass. The ITER design is such that a flexible cartridge is screwed onto the vas and bolted through the entree hole in the cover faculty. The stuff here needs to fulfill the undermentioned standards: high strength, must be able to defy high axial burden forces and let elastic distortion during flexing. The pick of stuff here would be titanium alloy – Ti-6Al-4V ( 32 ) . This stuff is widely used and so its database is instead complete. The stuff itself besides has low Young modulus ( 31 ) . The ductileness of the stuff is non capable to any alterations as the dosage it will be exposed to as the protection from the cover faculty itself minimise the barrage of the energetic neutron onto the cartridge.Divertorshypertext transfer protocol: //www.iter.org/doc/www/content/com/Lists/WebsiteText/Attachments/15/divertor_4.jpg Figure: The perpendicular marks and the dome of the ITER divertor ( 16 ) For the armour tiles of the divertor baffle countries[ 32 ], sintered wolfram ( W ) in the cold worked and stress relieved conditions will be a great pick. W has low eroding rate[ 33 ]as compared to Be and C, low tritium keeping ( 32 ) , and longer life-time ( 16 ) . However, the disadvantages of utilizing wolframs are such that it will do a big radiative power loss and might run if it is subjected to abnormal high extremum burden. Therefore, for countries that exposed to high thermic flux[ 34 ], W is non suited. Therefore, for such countries, carbon-fibre-reinforced C complex ( CFC ) will be used due to its high thermic conduction to have the higher heat fluxes. However, the usage of CFC must be minimised and restricted to the country mentioned above merely because it will gnaw chemically and retain tritium. Besides that, there are some belongingss alterations of CFC under neutron irradiation that must be noted. At low irradiation temperature[ 35 ], the thermic conduction of CFC might be 3-5 times lower than the unirradiated CFC. The lessening in the thermic conduction might take to a rise in thermic eroding ( 30 ) . However, the addition in eroding is still allowable within the life-time of the constituent. Detailss of fall ining engineerings for CFC are discussed at ( 38 ) . In short, the stuff choice for divertor baffles and dome would be W and CFC at the work stoppage points chiefly the perpendicular marks ( 36 ) . As there are advantages and disadvantages of utilizing CFC and W, another suggestion for the divertor stuff is using a coating of W on CFC. This might show a good solution and cut down cost but it is subjected to research. However, there is an issue with this solution. The thermic enlargement of CFC might post the job to the divertor itself. This can farther be overcome by lodging a thin bed[ 36 ]of Molybdenum ( Mo ) as intermediate. This had been tested by heating up to 2000 A °C without the failure of the constituents ( 36 ) . Full makings of wolfram coating is reported in ( 40 ) . For the overall cassette organic structure of the divertor, SS 316 L ( N ) -IG is selected as stuff for fabricating through cast/HIP or pulverization HIP method. The elaborate survey of the plasma confronting stuff[ 37 ]and its experimental consequences together with the belongingss of articulation can be found at ( 41 )NosologiesIn existent merger reactor, the nosologies system might non be that extended as compared to the experimental reactor like ITER, but the being of nosologies system and diagnostic device inside the vacuity vas is ineluctable in order to analyze the plasma parametric quantities and the wall parametric quantities. Like all other in-vessels constituents, nosologies system will be subjected to high neutron flux and high radiation ( 32 ) . The stuffs used for nosologies system today ‘s experiment experience really small radiation, hence new stuffs must be proposed to be used in the risky environment like ITER. To give an thought of how rough is the environment that the nosologies system will see, Table 3 is shown in Appendix for farther mention. In choosing the stuff for the nosologies system, the cardinal choice standards would be radiation opposition. ITER would utilize fibre ocular transmittal near the plasma. During merger, a few meters of overseas telegram will be subjected to important radiation flux, hence, radiation opposition for optical wavelengths would be a consideration. In the IR and the seeable part of electromagnetic moving ridges[ 38 ], stuffs such as silicon oxides fibre with optimized fluorine-doped nucleus will supply dependable fiber-optic transmittal in the high-radiation vacuity vass ( 42 ) . However, it is non advisable to utilize optical fiber inside the vacuity vass because embrittlement may happen at high degree of irradiation and in the vacuity vass and the fiber in the vacuity vas will hold to work outside its preferable part of electromagnetic moving ridges as mentioned above. In order to go through the fiber into the vacuity vass, a more optimal stuff must be searched for. In order to go throug h the wire into the vacuity vas into the ITER device, a multi nucleus ( 57 fibers ) device that can be remotely handled is being developed. For insulating ceramics[ 39 ]of wire, the wire and the magnetic spiral, it is non a large job as there is assuring campaigners exist. Single crystal and polycrystal aluminum oxide ( Al2O3 ) can be considered as the insulating ceramics with careful pick of operating temperature scope ( 32 ) . In fact, Al2O3 will be used throughout for the electrical dielectric of the constituents around the ITER. It is non expected that the stuff will see important debasement of its strength over its life-time in the reactor. However, it is of import to observe the effects of irradiation on the electrical belongingss of the electrical constituents and the dielectric stuff. Two of the of import physical consequence would be radiation-induced conduction ( RIC ) and radiation induced electrical debasement ( RIED ) ( 26 ) . The RIC consequence for the campaigner stuffs had been shown in Table 6 in Appendix. However, overall, there is no serious debasement of the belongingss that might impact the public pr esentation and the safety of the stuffs provided the careful choice of stuffs. For RIED, nevertheless, it is still non being understood yet, hence more R & A ; D must be done ( 43 ) . Mineral insulating ( MI ) overseas telegrams[ 40 ]are extremely immune to radiation every bit good and are widely used in atomic reactor ( 44 ) . Therefore MI overseas telegrams will be a suited campaigner for the magnetic spiral and overseas telegrams. The Windowss used in the nosologies system is besides subjected to radiation. The belongingss that are of concern when choosing the diagnostic window is radiation induced soaking up ( 26 ) . Sapphire can be considered as better stuffs for the Windowss when subjected to shorter wavelength as compared to fused silicon oxide due to its tolerance to gamma radiation[ 41 ]. However, diamond will be as the best stuff for nosologies Windowss as it can digest radiation from GHz part to IR part ( 32 ) . For plasma-facing optical component ( mirrors and reflectors ) , the mirrors will frequently confront with the job of deposition of scoured stuffs from other in-vessel constituents and subjected to intense radiation. Careful pick of mirror stuff must be made. For majority metal mirrors, the radiation and neutron might non present a serious menace although excess attention still hold to be taken to cover with the atomic warming ( 26 ) . The pick of stuff for majority metal mirrors can be Cu, W, Mo, SS or Al. For dielectric coated mirror, neutron irradiation can take to flaking and vesiculation and will damage the mirror. The similar job will happen with the multi-layer mirrors. Therefore, choice must be careful. Suggested stuffs for dielectric coated mirror are HfO2/SiO2 and TiO2/SiO2 ( 32 ) . For inorganic X-ray crystal, it will be unaffected by the neutron irradiation. Suggested stuff is graphite ( 43 ) . Bolometer is a device mensurating the power of electromagnetic radiation and therefore will be installed in ITER every bit good. Bolometer of stuff made of isinglass as the substrate and gold as meander used for JET is possible to be reintroduced in ITER as the testing of the bolometer is the JET reactor is non a job. However, the gold meander thought to hold been broken due to the transubstantiation and substrate puffiness ( 43 ) . Therefore, for ITER, alternate meander such as Pt will be considered. But the design for ITER at the minute still keep Mica as substrate and Gold as meander ( 32 ) , though more R & A ; D had been planned look intoing the possible substrate stuffs such as Al2O3, aluminum nitride ( AIN ) , CVD diamond, KU1 fused silicon oxide and Si3N4.MagnetsThe magnets, without uncertainties, are the most of import and critical component in a magnetic parturiency atomic merger power works. The spirals must be designed to accomplish superior public presentation in footing s of the current denseness and field at minimal cost without compromising the quality of the magnets ( 45 ) . Therefore, the choice of stuffs for the magnet remains a really important portion in a reactor like ITER. The pick of the magnets will be depend on the field, temperature and current. Among the suited stuffs that can be used to construct the superconductor magnets here are Nb3Sn and NiTi. Nb3Sn has a higher critical temperature and field than its opposition. However, NiTi is more malleable and the twist techniques are more conventional ( 32 ) . For cardinal solenoid and toroidal field spiral, the selected stuff is Nb3Sn because it allows these spirals to run at 12 T while being cooled by the supercritical He. Harmonizing to ( 45 ) , Nb3Sn is the lone stuff that is capable of supplying 12 T which is far more beyond that other commercially available superconductor but it will hold to undergo complex fabrication procedure which will be explained in the undermentioned reappraisal. For ITER, it is of import besides to guarantee that there is minimal hysteresis loss with high current denseness. NbTi will be selected for poloidal field spiral ( 46 ) . The construction of the toroidal field and the cardinal solenoid will be a lesion in a form of battercake and utilize the engineering ‘wind, react and transportation ‘ while for the construction of poloidal field spiral, the construction will be like dual battercakes ( 12 ) . Figure: Typical Agreement of Conductors Strand and Filaments ( 32 ) The music director jacket plays an of import structural function for the magnets. For poloidal field spiral, the fiction of the jacket will be an bulge subdivision which is assembled by butt welding. As a consequences, the tensile emphasis will rule here and 316L ( N ) austenitic steel is selected as the stuff for polodial field spiral music director jacket ( 12 ) . On the other manus, cardinal solenoid is extremely stressed and it will necessitate to rhythm twice per pulsation from 0 to 13T magnetic field. Therefore, the stuff for cardinal solenoid music director jacket demands to hold high output strength and high weariness opposition and have to be co-reacted through Nb3Sn heat intervention[ 42 ]. Titanium will be preferred stuff for cardinal solenoid music director jacket because it is preferred for a co-reacted jacket holding a thermic contraction coefficient that is near to that of Nb3Sn strands as the strand superconducting belongingss will be decreased by strain ( 32 ) . Besides Ti, Incoloy 908 will undergo precipitation indurating during co-reaction holding a high weariness opposition and is besides a suited stuff for the jacket music director. However, it is excess sensitive to emphasize accelerated grain boundary oxidization[ 43 ]( SAGBO ) which will ensue in O demands during the heat intervention procedure ( 32 ) and hence the heat i ntervention furnace must be controlled to keep low concentrations of O ( 47 ) . It is besides indispensable that the music director will be insulated with glass-kapton when being heat treated to guarantee good insularity ( 45 ) . Therefore, finally, Incoloy 908 will be used to envelop the overseas telegram although it is new and need to be co-reacted with Nb3Sn under carefully specified conditions ( 48 ) . Figure 7 in Appendix can be referred to see the overall cardinal solenoid clearly. The item fabrication procedure and weaving engineering is further discussed at ( 48 ) . For toroidal field spiral, the music director jacket can be built from modified 316LN[ 44 ]steel tubing which has a higher thermic contraction during co-reaction and acceptable break stamina. As such the big mechanical burdens on the toroidal filed spiral can be overcome by edifice of the thick steel spiral instances around the superconductors weaving battalion. These instances will see high emphasis locally with a cyclic constituent due to its interaction with poroidal field spiral ( 32 ) . The insularity of toroidal field spiral will utilize the same stuff as cardinal solenoid which is glass-kapton tape. The item fabrication procedure and weaving procedure of toroidal field spiral can be explored at ( 49 ) . Furthermore, to forestall fast fatigue cleft growing in steel due to the temperature of 4 K coolant of liquid He go throughing through it[ 45 ], a to the full established steel of category 316 must be used. Just to accomplish this intent, a particular category of strengthened austenitic steel have been defined. They are given name as EK1, EC1, JJ1, and JK2 during the R & A ; D of ITER. These steel are formed by increasing its N content which will increase the strength of the stuff and increasing its manganese content to increase nitrogen solubility in order to keep a good welding. EK1 and JJ1 will be used to beef up the interior leg basic elements[ 46 ]of toroidal field spiral instance and articulations around the spiral and intercoil construction. JK2 will be used to reenforce the Ti cardinal solenoid music director jacket. EC1 is used to beef up outer leg basic elements[ 47 ]of toroidal field spiral. ( 32 )External Heatinghypertext transfer protocol: //www.iter.org/img/sq-640-85/ww w/content/com/Lists/WebsiteText/Attachments/17/heating_4.jpg Figure: Proposed External Heating of ITER ( 17 ) The heating beginning of the merger power reactor must non be neglected every bit good in footings of stuff choice. This is because the external warming will be responsible to supply more than 10 % of the 50 MW input power of the merger power works. It is besides responsible to heat the temperature of the plasma up to the desired 150 million Kelvin. As mentioned in Section 2.1, there will be 2 beginnings of electromagnetic moving ridges that are responsible to heat up the plasma. Therefore, it is required to construct 2 radio-frequency aerial. The aerial will hold to prolong long continuance of plasma operation utilizing the high powers with the aid of Lower Hybrid Passive Active Multi-juntion ( PAM ) microwave launcher[ 48 ]. For ITER, there is already a pre-installed aerial. Therefore, another aerial had to be built from the abrasion and this might move as the mention for building of future merger power works ( 36 ) . The chief stuff challenge here is to manufacture a multi-waveguide construction for the moving ridge transmittal from the electromagnetic moving ridge generator to the vacuity vas. In ITER, the construction will necessitate the machining of Cu to the chromium steel steel by brazing. The fabrication of such devices face with a figure of proficient troubles which the chief troubles being the detonation bonding between the Cu and chromium steel steel for dual and ternary beds of stuff would deformed by the residuary internal emphasis after heat intervention and machining. Therefore, a particular brazing tool is required. A Gallic company, CEA, had proposed a engineering whereby the brazing tool allows commanding of the constituent contact force per unit area at high temperature under vacuity. ( 36 ) However, there is another type of electromagnetic moving ridge warming in ITER. It functions like a microwave with the lone difference being the microwave operates at megawatt power. It is called Electron Cyclotron Resonance Heating ( ECRH ) and it will heats the negatron utilizing an electromagnetic moving ridge of 170 GHz, the resonating frequence of the negatrons and the negatrons will so reassign its energy to the plasma ( 17 ) . Among the designs, there is a design that requires a â€Å" square corrugated wave guide † . If such wave guides is needed, rapid chilling will be required every bit good as the power transmitted by the moving ridge is high[ 49 ]. Such device does non presently exist and therefore will post a stuff challenge of holding a wave guide that is corrugated with high tolerance and welded under vacuity tight status ( 36 ) . However, there is presently a paradigm of wave guide being tested at such high power and the consequence is really satisfactory. The company involved here is the Heeze Mechanics. Due to a design alteration of ITER, a wave guide as mentioned above might non be required for the minute ( 36 ) . Therefore, the suited stuff for such wave guide is non investigated here.Remote HandlingRemote handling is highly of import in ITER as explained in Section 2.1 and all the stuffs involved in the vass will non be replaced manually on-site but will be repaired remotely. It is expected that the divertor will undergo serious eroding and is expected to be replaced 3 times during the life-time of ITER ( 36 ) . Therefore, DTP2 installation will be built in ITER to transport out all distant managing occupations. This will move as an in-vessel conveyance system to take and reinstall any harm faculties. The inside informations of how distant handling will assist to mend the vass are discussed in great inside informations at ( 50 ) and ( 51 ) . The stuff used is non specified here but it involved the usage of automaton and progress electronics that is available at current engineering.Cooling SystemThe chilling system in a merger reactor must be really advance as it is required to chill and pull out a theoretical power of 500 MW. However, the chilling system here will non present a job to a merger reactor like ITER. This is due to the fact that the current engineering can manage a atomic fission power works that let go ofing 1000 MW of end product power. The choice of stuff for the coolant of the merger power reactor can be every bit simple as H2O. Although there is other proposed design whereby the coolant selected will be liquid Li and it will acts as both the tritium breeder and coolant in a merger power works ( 25 ) , nevertheless, ITER will be utilizing the H2O as its chief coolant to pull out the heat energy. The status of the H2O used here are of 3.8 – 4 MPa with inlet temperature of 140 A °C and outlet temperature of 190 A °C with speed of about 5 m/s ( 31 ) . The H2O chilling system will be arranged to go around the cover faculty, the heat sinks, the divertor, the divertor cassette, the genteelness cover and the vacuity vas. The piping of the chilling system will be unstained steel[ 50 ]. However, it is of import that note that the B content in the steel will bring forth He as waste at topographic points where the steel is stopping points to the H2O chilling channels. Therefore, the B content in steel used for in-vessels chilling pipe must be reduced to 0.0010 % , so that the He coevals can be minimised. For all the magnetic spirals, it is indispensable that they are cooled by ace critical He of approximative 4 K.DiscussionDecisionMentions
