The Applications of Waterjets Essay Essays

The Applications of Waterjets Essay Essays The Applications of Waterjets Essay Essay The Applications of Waterjets Essay Essay In 16’Th century. Toogood and Hays for the first clip proposed waterjet propulsion system. as reported by J. S. Carlton [ 1 ] . At that period of clip. waterjet propulsions were used in high-velocity pleasance trade and work boats. However. in recent old ages. this system has been considered for big high-velocity trades. Consequently. many immense waterjet units have been used in broad scope of ships such as rider and naval trades. The waterjet propulsion is a complex system. On the contrary. the prison guard propellors are simpler. lighter and more efficient than waterjet system. However. the reaching of more efficient pumps. the necessity for seasonably presenting the critical commercial ladings. and the needed manoeuvrability for peculiar vass have made the use of waterjets more attractive. It is normal to split this type of propulsion system into a hull and a waterjet. It has been demonstrated that waterjet-hull interaction can impact the overall efficiency more than 20 % [ 2 ] . Normally. waterjet system is broken down into subsystems and an expressed modular attack is applied to analyse them. In order to measure the interaction between the hull and the jet. a parametric method is used. In 1980. an early part related to the jet-hull interaction is attributed to Etter et Al. [ 3 ] . A complete reappraisal of the bing dealingss for waterjet-hull public presentation is presented by Allison [ 4 ] . Van Terwisga [ 2 ] proposed a parametric propulsion anticipation method for the waterjet driven trade. Several numerical methods were devoted to analyze the flow behaviour in every portion of waterjet system by many research workers whose plants were submitted to the ITT Conference [ 5 ] . A complete design method that utilized the numerical strategy for the analysis of system parts has been used by CCDOTT [ 6 ] . N. W. H. Bulten [ 7 ] used CFD methods to plan and analyse the whole jet system. Besides. a flush-type waterjet propulsion unit was designed with different interior diameter impellers by Moon et Al. [ 8 ] . In a related work. analysis of a waterjet axial pump was performed numerically [ 9 ] . They investigated the public presentation of the axial-flow-type waterjet based on the fluctuation of the impeller tip clearance. The chief differentiation between the process implemented here and the old methods is that the present method applies the empirical. analytical and numerical methods at the same time to make a conceptual design of the waterjet system. By numerical analysis. recess design parametric quantities that describe theoretical account geometry have been specified. Furthermore. a simple two-dimensional recess theoretical account has been used here alternatively of a complex 3-D geometry. By this method. we have an acceptable propulsion system in a short clip. Consequently. a complete jet system design codification has been developed that combines the empirical. analytical and numerical methods. By sing the ship geometry restrictions and hydrodynamic belongingss. this package proposes suited jet conceptual design parametric quantities. Consequently. by utilizing simple 2-D sphere for recess canal and computed force per unit area distributions for different recess angles. an optimal recess has been proposed which leads to minimum losingss and maximal efficiency. 2. Basic Theory of System Waterjet propulsion system has three chief constituents: Inlet. Pump and Nozzle. Figure 1 shows typical waterjet agreement while Figure 2 demonstrates the idealised profile of the jet system. Sea H2O enters the system with the speed and leaves it with a different speed. The mass flow rate of the H2O through the waterjet is given by where and are the country of nozzle mercantile establishment and denseness of H2O. severally. The push produced by the system is equal to the rate of alteration of impulse: Appraisal of Wake ParameterThe waterjet recess provides flow from beneath the ship to the waterjet pump. The waterjet recess is located near the austere country of the ship. and as a consequence influx to the flower waterjet recesss will include a important sum of hull boundary bed flow. This means that for a flush waterjet recess. the flow come ining the waterjet recess has a impulse speed. . which is less than the ship velocity. . due to the inclusion of hull boundary bed flow. The sum of the hull boundary bed flow which is included in the recess flow is of import as it can impact the size. public presentation. and propulsive efficiency of the waterjet pump and must be taken into consideration during the design stage of a waterjet pump. Prediction of the recess impulse speed requires a thorough apprehension of the boundary bed speed profile which is instrumental for appraisal of the boundary bed thickness. where. is the unvarying velocity at far watercourse ( in this instance is considered to be the ship-speed ) and is the speed inside the boundary bed ( but here. it is the flow velocity at the recess due to the boundary bed ) . Figure 5 shows the computed values of aftermath parametric quantity and the boundary bed thickness as maps of ship speed. It is rather obvious that these two important parametric quantities decline as ship speed additions. However. the value of aftermath parametric quantity is about 0. 9 and this parametric quantity could be considered as a changeless measure. 4. Validation of Design Parameters As mentioned before. chief consequences of the current codification in the signifier of mass flow rate. pump caput and power have been compared with the available consequences of design package and theoretical account trial [ 6 ] . A scope of informations made available by the current codification was compared with that provided by the CCDOTT package [ 6 ] . Furthermore. comparing was made between the consequences of the current codification with the CCDOTT experiment for the design point shown in figures 6. 7. and 8. ‘WJ’ mark in comparing figures shows the consequences of the present method. Figure 6 shows the comparing of the mass flow rate for the experimental design point. the current method and fast ferry computed consequences which was offered by CCDOTT [ 6 ] . Besides. figures 7 and 8 present the same comparings for system caput and power. severally. These figures demonstrate that the bing mistakes between the consequences of the current codification and the experimental informations are by and large lower than 5 % . Based on the presented proofs. it can be concluded that the off-design consequences are rather dependable. The off-design consequences become peculiarly of import when the high-speed trade tends to make a maximal velocity over the chief bulge of the speed-resistance curve. because the power which is produced by the engine in off-design status is sometimes lower than the needed value The current codification is capable to calculate the recess country and pump diameter from impulse equation and geometry bounds. Based on these computed consequences. empirical theory was used to foretell the system losingss and basic geometrical parametric quantities. It was found that egg-shaped recesss have more advantages than the rectangular recesss. Experiments show that egg-shaped recess geometry with aspect ratio of 1. 3 is the best recess signifier for flush type jet [ 2 ] . Figure 9 shows the parameterized geometry of the recess profile. Obviously. a just recess profile has many advantages. but sometimes transom geometry and aft signifier of ship impose restrictions. To study the recess profile form and to analyse the flow over this sphere. some geometrical parametric quantities have been defined. Cavitation and separation could happen at two points at different recess speed ratios [ 11 ] . Figures 10 and 11 show the places of the cavitation and separation phenomena at low and high recess speed ratios. severally. The chance of cavitation happening was shown by the current work to be a map of the recess angle. ramp radius among other design parametric quantities. In the interim. Inlet angle was found to be the most influential parametric quantity which affects the cavitation happening and as such. the best recess angle was determined. Based on this observation. it was decided that commanding of the cavitation happening be done throughfluctuation of the recess angle while maintaining other parametric quantities constan t. Numeric Analysis of the Inlet DuctWhen planing a high-velocity waterjet recess. it is hard to accomplish an optimal design that is both efficient and has low drag. This is because cavitation occurs in the H2O that is unfavourable to both retarding force and efficiency. Cavitation by and large occurs when the local force per unit area on a organic structure traveling in a fluid drops to or below the vapor force per unit area of the fluid. When making the vapour force per unit area. little â€Å"bubbles† or pits are produced. These pits will fall in when they reach a higher-pressure part and do a little â€Å"water hammer† to organize. This phenomenon is called cavitation. Cavitation can bring forth the negative effects of noise. quiver. and eroding or harm to the recess. and hence. must be avoided in order to safeguard the efficiency and the retarding force. RANS2 codification has been used to happen force per unit area distribution around the recess canal. Planar geometry of waterjet recess canal has been modeled. Additionally. a rectangular part is constructed around the hull to stand for the boundaries of the ocean. Since the ocean is non really bounded. those boundaries will hold to either be placed adequately far off from the ship hull and defined as a wall. or placed closer to the hull to cut down the size of the job and defined as an gap. Once the mold was accomplished. an recess canal was analyzed for four different recess angles runing from 26 to 34 grades. and minimal force per unit area at the given recess angles were compared against the numerical findings of CCDOTT group [ 6 ] . This comparing in Figure 12 shows a good understanding between the proof base and numerical computations. Choice of the recess angle was done based on two different design considerations ; suited length of propulsion system and turning away of cavitation. Finding the optimal recess angle requires a test and mistake advancement. Consequently. a big angle was selected and possibility of cavitation was examined. gratuitous to state that presuming a proper safety factor is really of import in this advancement. Cavitation figure is defined as: ( 22 )When â€Å"† . cavitation starts. This implies that high cavitation Numberss give less hazard for cavitation. Figure 13 shows contours of cavitation Numberss in XY plane while Figure 14 presents the cavitation figure at the center line of the system for two different recess angles. These figures could furthermore bespeak how and where the cavitation could happen. Figure 14 shows how the system will run at a design velocity scope without cavitation at the recess incline when the recess angle becomes 26 grades. View old figure3-D analysis of recess canal which was done by CCDOTT shows that the minimal force per unit area occurs at the center line. On the other manus. the consequences of the current survey have good conformance with those of the mentioned 3D analysis. Therefore. Figure 14 could be considered as a dependable beginning for planing the recess canal. 7. Decision Coincident achievement of the conceptual and basic design every bit good as the analysis of waterjet propulsion system in a individual procedure is a cumbrous undertaking. Many analytic and empirical methods have been proposed to measure the influential parametric quantities of this system. Numeric methods are used for the analysis of the system public presentation. albeit non in a design procedure. In the current work. a peculiar method has been presented which covers all phases of the design and the analysis of waterjet propulsion system which has besides been validated by dependable consequences. Two different codifications have been developed. one for the analytical appraisal of the chief waterjet propulsion system parametric quantities and the other of numerical probe of the recess canal impacts. In the current strategy. a practical method is used to foretell the powering features of systems. Prediction of the public presentation of the waterjet system at the design point starts with finding of the needed push. jet diameter. shaft HP. and RPM which is done by a developed computing machine plan. During the elaborate hydrodynamic optimisation survey. the RPM. radial blade lading distribution. and other parametric quantities of the waterjet were varied to get at the optimal design for this power degree. Computed values of flow rate. caput rise. and power versus the speed ratio were compared against before reported experimental and numerical consequences. These comparings demonstrated good understandings bespeaking that the separate handling of the waterjet and hull designing procedure appears to be rather possible. The adoptive attack leads to a set of parametric dealingss that describes the interaction between the hull and the waterjet system. Because of this modular attack. the consequences can merely be refined during the design procedure of the vas. Empirical dealingss have been used for preliminary appraisal of the needed power for the vas. From this deliberate push and the assessed internal losingss in the waterjet system. the needed pump power can be found. Possible cavitation at the recess canal leads to erosion or quivers which must be avoided. In this paper. cavitation features at the recess were found by looking at the force per unit area distribution of the H2O around the recess gap. Consequently. the possibility of cavitation was investigated and controlled by close examination of the cavitation figure. Along the same line. optimal recess geometry was found based on the observation of force per unit area distributions at different recess angles. This whole procedure was achieved by a 2-D numerical codification written for the flow probe at the recess of the waterjet system. Numeric findings of the current 2-D codification compared with the earlier consequences of the 3-D mold show an first-class lucifer between the force per unit area distributions. As a consequence. one may reason that a drawn-out procedure of 3-D calculation can so be avoided and that similar consequences can easy be achieved by a 2-D analysis which is a less arduous procedure and saves much computational clip. Main geometrical parametric quantities for the design of waterjet propulsion system have been determined by the present method. By using these of import parametric quantities. a interior decorator is able to foretell the waterjet public presentation on a ship before geting at the basic design phase. Gratuitous to state that there are other considerations that must be taken into history which include necessary figure of jets. place of the propulsion system. and the consequence of the system on compartmental agreement of the ship.Notes 1Center for the Commercial Deployment of Transportation Technologies [ 1 ]Carlton.

Quotes from Women About Feminism

Quotes from Women About Feminism Learn what famous women have had to say on the subject of feminism with this collection of quotes. Gloria Steinem I have met brave women who are exploring the outer edge of human possibility, with no history to guide them, and with a courage to make themselves vulnerable that I find moving beyond words. Adrienne Rich I am a feminist because I feel endangered, psychically and physically, by this society and because I believe that the womens movement is saying that we have come to an edge of history when men- insofar as they are embodiments of the patriarchal idea- have become dangerous to children and other living things, themselves included. Erma Bombeck Weve got a generation now who were born with semi-equality. They dont know how it was before, so they think, this isnt too bad. Were working. We have our attache cases and our three piece suits. I get very disgusted with the younger generation of women. We had a torch to pass, and they are just sitting there. They dont realize it can be taken away. Things are going to have to get worse before they join in fighting the battle. Marilyn French My goal in life is to change the entire social and economic structure of western civilization, to make it a feminist world. Robin Morgan Quotes If I had to characterize one quality as the genius of feminist thought, culture, and action, it would be the connectivity. Susan Faludi Feminisms agenda is basic: It asks that women not be forced to choose between public justice and private happiness. It asks that women be free to define themselves- instead of having their identity bell hooks As all advocates of feminist politics know most people do not understand sexism or if they do they think it is not a problem. Masses of people think that feminism is always and only about women seeking to be equal to men. And a huge majority of these folks think feminism is anti-male. Their misunderstanding of feminist politics reflects the reality that most folks learn about feminism from patriarchal mass media. Margaret Atwood Does feminist mean large unpleasant person wholl shout at you or someone who believes women are human beings? To me its the latter, so I sign up. Camille Paglia I consider myself 100 percent a feminist, at odds with the feminist establishment in America. For me the great mission of feminism is to seek the full political and legal equality of women with men. However, I disagree with many of my fellow feminists as an equal opportunity feminist, who believes that feminism should only be interested in equal rights before the law. I utterly oppose special protection for women where I think that a lot of the feminist establishment has drifted in the last 20 years. Simone de Beauvoir To emancipate woman is to refuse to confine her to the relations she bears to man, not to deny them to her; let her have her independent existence and she will continue none the less to exist to him also; mutually recognizing each other as subject, each will yet remain for the other an other. Mary Daly The fact is that we live in a profoundly anti-female society, a misogynistic civilization in which men collectively victimize women, attacking us as personifications of their own paranoid fears, as The Enemy. Within this society it is men who rape, who sap womens energy, who deny women economic and political power. Andrea Dworkin Feminism is hated because women are hated. Anti-feminism is a direct expression of misogyny; it is the political defense of women hating. Rebecca West I myself have never been able to find out precisely what feminism is: I only know that people call me a feminist whenever I express sentiments that differentiate me from a doormat, or a prostitute. Christabel Pankhurst We are here to claim our rights as women, not only to be free, but to fight for freedom. It is our privilege, as well as our pride and our joy, to take some part in this militant movement, which, as we believe, means the regeneration of all humanity. Audre Lorde But the true feminist deals out of a lesbian consciousness whether or not she ever sleeps with women. Charlotte Perkins Gilman So when the great word Mother! rang once more,I saw at last its meaning and its place;Not the blind passion of the brooding past,But Mother- the Worlds Mother- come at last,To love as she had never loved before- To feed and guard and teach the human race. Anna Quindlen Its important to remember that feminism is no longer a group of organizations or leaders. Its the expectations that parents have for their daughters, and their sons, too. Its the way we talk about and treat one another. Its who makes the money and who makes the compromises and who makes the dinner. Its a state of mind. Its the way we live now.

Regulatory Theory Essay Example | Topics and Well Written Essays - 1750 words - 1

Regulatory Theory - Essay Example In fact, before these far-reaching reforms, telecommunication service provision remained a monopoly of state corporations or in rare cases, was monopolized by private entities. Due to the fact that the provider of telecommunication services in most cases was the government, the regulation of this sector was never quite independent since, all the policy-making and regulatory powers lay with the government and its agencies (Welfens, 2010). Therefore, the management of telecommunication frequencies and the responsibility of operating networks were a preserve of the government of the day (Davidson et al., 1986). For many developed countries, this classical approach to ICT management was quite profitable for some time, given that the increased international tariffs for telecommunication services covered for the subsidized local tariffs. In addition, with the decreased telecommunication cost that resulted from technological advances, the classical approach to ICT operations did well for mo st developed countries (Welfens, 2010). Unfortunately for the developing and the underdeveloped countries and regions, the classical approach to ICT operation did not work well. The reason for this scenario being that these countries’ networks were somehow restricted to major cities and towns, implying that only the middle and high socioeconomic status citizens could access and utilise ICT services in these countries. While the low socioeconomic status citizen had to make do with poor quality telecommunication services and long waiting lists, the high-income end of the population were advantaged by the cross-subsidisation of ICT prices (Welfens, 2010). Regrettably, the classical approach to ICT regulation did not generate investment income for the developed and the developing countries alike. During the 1980s and the 1990s, the role of telecommunication in the economic growth of countries and the entire world became rather apparent, leading to the development of a number of r egulatory and competition polices, even though to a limited extent, in many countries (Koops et al., 2006). Besides, regulating competition, the regulatory and competition policies were expected to instill dynamism, innovativeness, augment availability, accessibility and increase ICT choices and lower tariffs for customers. The first effect of the wave of ICT reforms that peaked in the 1990s was the privatisation of telecommunication service operators. The second effect of the ICT regulatory policies was the introduction of new varieties of services such as mobile telephony and value-added services (Koops et al., 2006). This paper thus explores the need for the regulation of ICT, whether regulation works in the interests of the public and the implications of convergence and innovation on ICT regulation. The Importance of Regulation That the core role of regulation in any industry is to enable sustainability, growth and development is quite apparent and cannot be overemphasized. Ther efore, the information and communication technology sector, like the other sectors of an economy, requires a strong legal framework and regulatory mechanisms to function for the betterment of the public. A number of reasons have since been identified to underlie the need for the regulation of information communication and technology. Generally, ICT the need for ICT regulation arises from the recently observed structural changes in the communication industry. The transformation of the industry from a monopoly to a competitive one in many a country has particularly necessitated its stronger regulation (Baldwin et al., 2012). Therefore, the regulation of the ICT sector has been particularly important in the creation of an effective environment for fair competition that supports both

Todays Business Environment of JetBlue Case Study

Todays Business Environment of JetBlue - Case Study Example Indeed, business has been growing as a result of the strategy but the problem is that it is not fully sustainable in the long run which has influenced the airline to seek leadership changes. Â  Today’s business environment is characterized by an increasing intensity of competition, rapid technological changes as well as the ever-changing needs of the customers and the employees. Success in this dynamic and competitive environment depends on the extent to which the organization develops, implements, monitors and evaluates its business strategy (Temtine, 2001:1 as cited in Roussow 2003). At times the organizations fail not because of the strategy but the execution of the strategy. Thus the aim is to develop a strategic management and competitive advantage plan in order to ensure the viability of the airline in the long run. Â  Against all odds, JetBlue managed to gain a competitive advantage since its inception due to different reasons. Through embarking on the value chain, the organization managed to attract many customers since it was rated as one of the airlines offering best service. The concept of value chain entails that value chain entails that any business ought to separate its business systems into various activities which can add more competitive advantage to its operations (Robinson 1997). For instance, the aim would be to offer the customers with first class service which would be valuable in other activities to the customers. Part of the system of value chain involves identification of the customer needs as well as the generation of sales. There would also need to offer support to the customers after the services have been sold to them. The primary activities of value chain would also involve infrastructural development which can support the control systems as well as company culture.

Dead Stars Essay Example for Free

Dead Stars Essay 1. Is the title â€Å"Dead Stars† appropriate for the story? Justify. Yes, the title Dead Star is very appropriate for the story. In the story, dead stars symbolize a dream for something that is nonexistent. Alfredo loved Julia. She was his dream, his star. He thought there was love there. But like a dead star which is far away, and whose shine could actually be the leftover traveling light from it, he was a long way from getting the girl. And when the time came that they parted from each other, Alfredo kept on wishing to be with Julia but when finally they met again, he realized that the love he thought was possible was in fact, never was. The spark that he saw in his star was gone a long time ago even before he realized it. When he was with Julia after many years of separation, it was then that he learned that all along, he was dreaming for a love that was only an illusion, he was dreaming for a dead star. 2. What Filipino practices are evident in the story â€Å"How My Brother Leon Brought Home a Wife†? Perhaps one of the most evident Filipino practices shown in the story is the formal introduction of the wife-to-be to the parents of the man before the actual wedding. This is done as part of giving respect to the parents and also to get their blessings. This is a very important Filipino trait and it still done until now although there are instances that it is neglected. Another is the prevailing rule of the father in the family which is the common arrangement of the family system here in the Philippines. It was also shown in the story the tendency of the Filipinos to test the girl or boy so as tofind out his/her real personality and intentions. This was greatly depicted in the character of Leons father through Leons brother. 3. Does Filipino custom explains that love is absent when you dont see the person? Filipinos are best known for being loyal people especially when it comes to love. This is mainly because our culture dictates that loving should be in this way, with all honesty and loyalty and being stick-to-one no matter what the hindrances there may be. These hindrances may include the long  distance between two lovers but still the relationship grows stronger because of the distance and this is one proof that even when we Filipinos dont see our love ones, we still continue to love them deeply. In the case of Alfredo and Julia in the story Dead Stars, Alfredo had only thought that it was love that he had for Julia but in fact it was only a misconception and misinterpretation. So, the question could not be applied to them because at the first place, it wasnt love that Alfredo felt for Julia before they were separated. However, there are really instances when love fades away due to the long absence of our love ones. This is only a case to case basis and it does not generalized the Filipinos. To answer the question, I would say no for love is not grounded in physical presence only. Personally, I would say that love for another continues to live even when the person is not present as long as it is being acknowledged and appreciated, otherwise, it will fade away.

Analysis of Things Fall Apart Essay -- Chinua Achebe

Different countries have people that hold many different views and beliefs. In Nigeria the Igbo area is located in the southern area of the country. And within this area is Umuofia, which is where the Ogidi tribe lives. These people have beliefs that rest strongly on religion and faith in god. "Things Fall Apart" by Chinua Achebe takes a look at the life of an African tribe that has been isolated from the outer more technologically advanced world where science has become a part of religion proving that certain things live sickness are not caused by evil spirits. But the African tribe has no knowledge of this and they live in a society where there traditions, beliefs and there forms of communication differ from are own. In Umuofia, traditions are an important part of their lives. They celebrate festival that has been celebrated by their people for hundreds of years. ?The feast of the New Yam was held every year before the harvest began, to honor the earth goddess and the ancestral spirits of the clan?. They beliefs were that if they prayed to the earth goddess she would give them a good season to grow their crops. They had other traditions in their tribe, like the process you must follow to marry. After coming to the ugi they would bid for the price of the woman in broomsticks because they felt that talking with cowries was insulting to the woman because it was like buying something at the market. ?. Akueke?s bride price was finally settled at twenty bags of cowries?. This tribe believed that the groom must pay to have his wife, which is how they had always done it. To be successful in Umuofia you want to, have many wives and many kids and have many barns full of yams and have titles with the clan. Okonkwo was one of the w... ...e had such a temper he would beat them. And because of his pride he would never stop until he was done beating them. Okonkwo had a very tough personality and was known through out the land as being a fierce fighter who had claimed five heads of his opponents. This culture really varies from ours in many ways because of the ways they communicate is so different from how we would ever consider doing here. The Igbo tribe has values beliefs and ideas that are strongly rooted in the gods. The way in which they communicate and interact shows a lack of respect towards woman and they are treated like slaves to men. Achebe?s novel ?Things Fall Apart? gives a good insight into the aspects a of a culture that before him had never need explored, and it gives the reader a good look at what the beliefs, values and the way the members of the community communicate and interact.

Economic conditions Essay

In this essay I’m going to argue that social, political, or economic conditions cannot alter the nature and meaning of art, with specific reference to works of art from Baroque and Rococo epochs. Evaluating a work of art is always a complicated task. Since the perception of art and beauty is highly subjective, it’s hard to think of universal criteria to measure artistic qualities of a certain piece. However, there is a broad consensus among the critics that there are certain criteria they apply when judging an art work. It’s possible to focus on four main criteria to judge an art work. First and foremost, the piece should be aesthetically pleasing, i. e. correspond to the all-common notion of beauty. It should be harmonious and evoking positive, elevated feelings. While there is a trend among some contemporary artists to make their pieces arouse indignation and disgust with a view to delivering a certain message or merely astonishing the public, I strongly deem that art and aesthetics are inherently linked. For instance, a typical example of baroque sculpture — St. Theresa in Ecstasy of the church of Santa Maria della Vittoria, Rome created by Bernini — is perfect in its form, since it captures the beauty and harmony together with motion and energy. Same is true about Rococo sculpture: looking at ‘Amour menacant’ created by Etienne Maurice Falconet, it’s impossible not to admire the high degree of sophistication and perfection the statue of the little angel embodies. The second criterion I’m going to use is quality of workmanship, i. e. the mastery of artists’ skills. Another criterion which is very important is the uniqueness of artists’ manner. Great artists stand out for the peculiarity of their individual style. Some of them prefer to pioneer new forms and techniques, yet this is not a prerequisite for creating a style of your own. Many talented artists don’t break away from the tradition but simply find their own niche within the existing patterns of expression. While some artists of the Baroque and Rococo epoch were considered rebellious, e. g. Michelangelo Merisi da Caravaggio, they didn’t violate basic rules of harmonious and aesthetically pleasing artistic expression. Jean-Honore Fragonard’s manner was also innovative in many instances, sine he introduced a delicate interplay of light and shadow as well as implicit eroticism into mainstream French painting, however he adhered to the generally accepted notion of what beauty and art are. Finally, the forth criterion is the message the piece is trying to send. Here it’s necessary to take into account the importance and relevance of the message as well as how successful the piece is in delivering it. Baroque and Rococo painters mainly focused on the depiction of mythological and religious scenes as well as the scenes from the daily life of the upper circles of society. While both themes that dominated the artistic discourse might seem to be detached from the real life, they served an important goal of educating the public about mythological and religious narratives or captured the spirit of their times through the portrayal of the privileged members of society The most persuasive proof of the thesis that social, political, or economic conditions cannot alter the nature and meaning of art is the fact that nowadays we still admire great works of art irrespective of the epoch they belong to.

Corporate Law- Promoter Essay

Rolly approached Molly and Polly and asked them to be shareholders to form a company. Then Rolly acquired a shop lot worth RM350,000 in order to prepare for the company in future. She bought this shop lot below the market price as the vendor was looking urgently to sell it. After the company is formed, she sold the shop lot to Jiggles Sdn. Bhd. at market price. Thus, she gained a lucrative profit of RM200,000 without the knowledge of any other party. Definition of promoter Section 4(1) of the Companies Act 1965 defined promoter is a person preparing prospectus. (not limited to this definition alone) According to Cockburn CJ in Twycross v Grant (1877), a promoter is a â€Å"person who undertakes to form a company with reference to a given object and set it going and takes the necessary steps to accomplish the purpose†. (Company Law in Malaysia, pg42) A promoter may be a natural person for example when the sole proprietor promotes a company to take over his business. (Company Law in Malaysia, pg42) The promotion process includes negotiations, registration of the company, obtaining directors and shareholders and preparing the paper work. In this case, Rolly is the promoter of Jiggles Sdn. Bhd as she meets the definition of promoters. She is a sole proprietor who selling cupcakes, promoted the company to take over her business. Besides, she also obtained shareholders by approaching Molly and Polly. Promoters’ duties Thus, Rolly is under a fiduciary relationship with the company. She has an obligation to act in good faith for the best interest of the company and must avoid conflict of interest which will affect her behavior. Under the duty of promoter, promoter should not make secret profit, defraud the company by active concealment, disclose confidential information, hides any personal interest. On the other hand, they should make a true and honest account to the company for his dealing on behalf of the company and make full and frank disclosure to shareholders and directors. In this case, Rolly had breached her fiduciary duty. She had made a secret profit of RM200,000. She did not make full and frank disclosure of her interest to the shareholders and directors of the company. She had hide her personal interest. Thus, where Rolly fails to declare her interest in the contract with the company she is promoting, the contract is voidable at the company’s  option as in the case of Erlanger v New Sombrero Phosphate Co (1878). Remedies of breach of duty As in the case of Erlanger v New Sombrero Phosphate Co (1878), the contract is voidable at the company’s option. Thus, the company may avail itself of the following remedies. The company may rescind the contract, claim for damages or recovery of secret profit. Rescind the contract-The company may choose to put an end to the contract. If the company terminates the contract, both parties are to return the benefits received. Thus, the company has to return the shop lot and Rolly has to return the purchase price received. Damages- The court may order Rolly to pay damages to the company for loss incurred when rescission is not possible, as in the case of Re Leeds and Handley Treatres of Variety. Recovery of secret profits- When rescission is not possible or the company does not want to rescind the contract, the company can recover the secret profit made by Rolly.

How does Othellos character change over the course of the play Essay Example

How does Othellos character change over the course of the play Essay Example How does Othellos character change over the course of the play Paper How does Othellos character change over the course of the play Paper Othello changes the most drastically, from being an affectionate and respectful General, modifying into a violent, ruthless man. A. C Bradley quite rightly quotes If such a passion as jealousy seizes him, it will swell into a well-night incontrollable flood. This dormant emotion would inevitably be released in a fury of furious rage once Iago penetrated his delicate mind. From the start of the play the audience encounters a well-honest decent person, even being respectful to Brabantio Good seignior after he accuses him of stealing his white ewe. Throughout Othellos life, he has earned respect, climbing his way up the ranks, despite his skin tone, and expects respect back. Displaying his intense love for Desdemona, I won his daughter almost treating Love as a game, but, loving her deeply that when he kills her out of sheer anger, suicide is the only escape from a life without his love. As Iago works his magic scurvy and provoking terms against your honour, the seeds of jealousy has been growing, all it takes for Othello to tip over the edge is ideas, trickling over the course of the play, growing his jealously, and when the seeds have blossomed into a green monstrous mess of abstract thoughts, Othello will arise, black vengeance, from thy hollow cell! . Othello was written around 1603, racism was ripe, racism was accustomed and Othello knew this. Marrying a white woman and becoming a General was seen as bizarre for a Black man to accomplish. People would naturally become hostile, thick lips, and Othello would naturally be suspicious of his surroundings. Growing up in a white dominated society, maybe Othello felt some compassion to break away from the ideology that all Black people are inferior. So locked away in his mind he always knew he would be the outsider, his mind is like a dam, jealousy and resentment are blocked by the blockage of Love, once Iago has chipped away at this blockage Not to affect many proposed matches Of her own clime, complexion, and degree the whole structure begins to crumble. There are many racist remarks throughout the play, Moor being the most prominent. At the start Othello seems reluctant to address it, soft phrase of peace, Othello has done seven years pith. His time in battle has matured him into a well-spoken individual, My very noble and approved good masters, this shows the level of respect he has for others. In the beginning the audience become emotionally attached to Othello, hes confronted with racial prejudice by jealous individuals, and yet he confronts it gracefully. Roderigo is perturbed that Brabantio rejects any approval of him marrying his Daughter, and with Othello being with Desdemona It is silliness to live, when to live is torment, it further enhances his aggravation. Iagos jealousy and anger stems from Othellos judgments when choosing a lieutenant and the fact that he thinks Othello has cuckolded him. Both these disputes exist because of Othellos actions, but are confronted with racial hatred. Othello is constantly bombarded with racial slurs, which takes its toll towards the end. Othello realises, maybe, he isnt worthy of Desdemonas love and in effect causes him to become confused and dazed. Desdemona had become a victim of Othellos downfall, jealousy. Othello already had some suspicions concerning Desdemona due to their different racial background. He is torn between his love and Honest Iago. He yearns for affection and when this affection is troubled he begins to question his relationship with Desdemona, Act 3 Scene 3 is when his troubled mind begins to emerge If she be false, O then heaven mocks itself; Ill not believe it. He desperately needs Desdemonas love but the very thought of deception grows like a disease in his mind. When we first encounter Othello he freely expresses his emotions, I love the gentle Desdemona, showing no regard for the racial prejudice that exists. He has reached the highest peak in his life, marrying Desdemona. Hes not a troubled man, he doesnt expect trouble to plague him. In effect hes a simple man, only doing what is required of him. The trust and respect he has accumulated keeps him afloat My services which I have done the signiory Shall out-tongue his complaints, the virtues in Othello have become a pleasing factor resulting in equal respect being shown back to him, apart from the isolated references to Othellos colour. The term Ignorance is bliss comes to mind when thinking of Othello, up until Act 3 Scene 3 Othello hasnt been bombarded with Iagos scheming ways, and so, has no reason to be questioning his love, but the thoughts were never implanted by Iago, but were rather dormant, always in Othellos mind but never triggered, until Iago started to tap at this unforgotten idea, breaking the shackles that once tamed this beast. Once its been released, it starts to consume his mind, bit by bit. When Cassio left my wife. What didst not like? From this point Othello becomes a victim of Iagos mind games and due to Othello being too trustworthy to Iago always referring Iago to Honest Iago the bond he shares with him is almost unbreakable. This cocktail of emotions in Othello becomes too unbearable, the trust of Iago, with the Love of Desdemona becomes a juggling act, and with the added emotion of Jealousy it all becomes too much for Othello. Iagos plan is now in full effect and Othellos transformation begins both physically and mentally, as he develops a headache from the overwhelming knowledge being outlined to him I have a pain upon my forehead here. The information hes just been told is so damaging that it even has a physical effect on him, desperately trying to fight back his emotions from Desdemona. At this point Iago just serves as a catalyst, speeding up the process of decay off Othellos mind. Feeding lies to Othello, the change becomes ever more unbearable for him One of this kind is Cassio, In sleep I heard him say, Sweet Desdemona' In such a short amount of time, from professing his Love for Desdemona, even going so far as to say When I love thee not, Chaos is come again which Othello is professing that if he stops loving Desdemona then Chaos would rid the world, which is a bold statement to make, where the audience thinks nothing could stop this man from loving Desdemona. But within the same scene, the very same person who claimed that Chaos would come if his love stopped quotes Ill tear her all to pieces! This shows the power and influence Iago has over Othello; he can change him drastically without much effort or evidence and the change is permanent Your mind perhaps may change Never, Iago, the manipulation was all too easy for Iago, and now he has accomplished what he intended which was to become lieutenant Now art thou my lieutenant. Now Iago retreats back into the shadows only to watch how Othello shatters his jelly-like, unstable mind. Over the course of the remaining play Othello sees no recovery from this, hes fixated on Desdemonas cheating ways and the pure innocent Desdemona has no idea why Othello is acting differently, only adding fuel to the fire when Othello asks for the handkerchief, but Desdemona trying to change the topic to Cassios reinstatement, it only infuriates Othello further as Cassio is the reason of his suffering and with Desdemona talking about him it gives him more reason to hate, Zounds and storms off. Further acts of physical occurances begin to plague Othello once more, with him falling into a trance, it evidently shows the sheer amount of jealousy that has overtaken his life. He loathes Desdemona but needs her love. This battle of the mind becomes unhealthy for him, Ist possible? Confess? Handerkerchief? O devil! Even the way Othello speaks has changed, usually speaking in verse, now his speech mimics his anger. Othello has almost taken on the role off Iago, scheming behind Desdemonas back, plotting against her, the same Jealousy that consumed Iago has taken over Othello, in a more aggressive fashion. Intense love delves into intense hate. How shall I murder him, Iago? Othello, you could say, is under the spell of Iago, he listens to him in every instance, as the audience reading this, it becomes shocking at how far Othello has changed, at the start of the play Othello, judging by his kindness to others, it would seem as he would never kill outside of battle. Now hes becoming just as devious as Iago. Which leads to the inevitable death of the last women he will love. Othellos character is a victim of foul-play. From being a courteous person to a rampaging ram. Othello is the perfect example of what deceit and lies can do to one without a mentally strong mind, his intense love for Desdemona is so deep that he cant fathom a life without a perfect relationship with her, one little idea and it destroys him, he thinks because of his race he may not be worthy of her, so tries desperately to cling onto to the one thing he treasures most. But insecurities in himself become his ultimate downfall. Of one not easily jealous but, being wrought.
