Design of a three phase separator in oil and gas Thesis

Design of a three phase separator in oil and gas - Thesis Example Three-phase separators efficiently separate the effluents from gas oil and water to allow for individual treatment of the mixed fluids (Lyons, William, and Gary 165-173). The three-phase separator is for processing manufactured fluids from an oil sump. Its division is into an emulsion, oil separator, and water compartments. The separator includes a water dyke and control system that mechanically regulates the position of the water weir to retain the oil emulsion interface in the emulsion section significantly constant. The separator operating parameters and standards vary in accordance with the target fluid and the type of separation. According to the CDS separation technologies, the standard of a three-phase separator is in relation to the extent of its applications (Lyons, William, and Gary 185-197). The three common standards include the horizontal three-phase separator with a weir it is the lowest standard. The second standard, the separator with oil bucket and water dyke it is more advanced and requires no active interface control and a high standard separator is the one with the boot for moderate waters. The design of hydrodynamic of liquid-liquid separation in the three-phase separator is basing on the rules laid by the American Petroleum Institute design principles. Peng-Robinson equations of stage and successive substitution deem useful during the modeling phase of the separators (Arnold, Ken, and Stewart 129-134). The design appreciates the Monnery and Svrcek model in determining critical parameters of the vertical and horizontal separators like the diameters and lengths at different pressures. The design pressure decreases at every stage of the process. Modeling for optimizing the pressure of the three separators reduces the amount of gasses produced with oil in the multistage separators. Optimizing this model applies a written computer simulator with the use of

Karen Newman Othello Criticism

Karen Newman Othello Criticism In her 1987 article And wash the Ethiop white: femininity and the monstrous in Othello,1 Karen Newman sets out re-examine prior critical analysis of Shakespeares Othello with the goal to re-read Shakespeare in ways which [] contest the hegemonic forces, [his] plays at the same time affirm (158). Her argument scrutinizes the the male-dominated Venetian world (152) of the play and the criticism that it has generated against correlating historical perspectives. Her main thesis about the play asserts that the union of Desdemona and Othello represents a sympathetic identification between femininity and the monstrous which offers a potentially subversive recognition of sexual and racial difference. Employing a feminist approach Newman reveals the racial and gender prejudices inherent both in the play and the critique levelled at it from 1600 through to 1980. In seeking new ways of reading Othello Newman draws on Derridas poststructuralist ideas to establish parallels between the relationsh ip of gender and race. She contends that Desdemona and Othello are equally marginalized by Venetian society; Othellos race and Desdemonas progressive sexuality presenting equivalent risk to the dominant white male society. In verifying how these attitudes pervade the play itself, Newman points out that fear of miscegenation functions on two levels. Firstly Shakespeare uses the white mans fear of the union of black man and white women (144) to generate the plot, and secondly through the binary opposition of black and white characteristic of the plays discourse. To substantiate she quotes from the play: Black ram tups white ewe and O, the more angel she, And you the blacker devil. The last line illustrates what Newman terms rhetorical miscegenation. Outlining the frequency with which black and white were used to denote polarization during the Renaissance, (145) she comments on how the emphasis in Othello of Desdemona as the idealisation of fair female beauty is usually read to emphasise the contrast between these two characters, and declares that contrary to early critics she views Desdemona not as a representative of opposition to blackness and monstrosity, as black is to white, but as identifying with it. Newmans assertion that the play is structured around a cultural aporia, miscegenation is the first cornerstone of her argument. Newmans next device is to establish a link between femininity and the racial attitudes inherent in the play. Again she refers to Ridleys criticism, claiming that his choice of example portrays a generalization of women as petty, thereby confirming his gender prejudice. Ridley has displaced the struggle of white against black man onto a cultural femininity. Newman is sympathetic to Stephen Greenblatts (1980) view that Othellos identity is reliant on his loss of his own origins, an embrace and perpetual reiteration of the norms of another culture, but criticises this focus as failing to recognise the other as black and female: Othello internalises alien cultural values, but his otherness remains apparent, dividing him from that culture and thereby linking him to the plays other marginality, femininity. Newman claims critical considerations with regard to the symbolic significance of the handkerchief reflect gender prejudices. Reigning critical preoccupations result in the significance of the handkerchief being limited to a sign of adultery. Contrasting this she terms the handkerchief a snowballing signifier, acquiring figurative and literal meaning as it passes from hand to hand. Newman contests psychoanalytical readings as problematic since they privilege a male scopic drama casting the women as a failed man once again negating her otherness and limiting female sexuality to fetish. (156) Identifying racial attitudes as inclusive of attitudes towards black sexuality, Newman references popular travel accounts of the time, outlining African as presented descriptively [] but also mythically (148) concluding: always we find a link between blackness and the monstrous, and particularly a monstrous sexuality. These attitudes Newman asserts assimilated into the drama of early modern England. (149) Newman observes the portrayal of Desdemona as voracious and devouring with a greedy ear; threatening to masculine perceptions of femininity. Her desire is presented in terms of an aural/oral libidinal causing Othello anxiety. Newman sees this anxiety as having a duel source the monstrous difference it invokes against his adopted culture, and that it allies her imagined sexual appetite with his own. Othello and Iago are linked in representing white male sexuality in the play. Simultaneously and paradoxically Othello also represents the threat to it. Newmans investigation of historic al criticisms surrounding femininity as represented by Desdemona, uncovers several ironies. Rymer and Cinthio in a cautionary moral link Desdemonas social disobedience to her sexual duplicity. Othellos punishment of Desdemona however simultaneously confirms the cultural prejudice which labels him a monster. In addition Iagos dramatic construction which leads Othello to see Desdemona as a whore, demonstrates how theatrical representation can provide false influence. Newmans undoubtedly subscribes to a feminist school of criticism, seeking to expose the nature of gender inequality and opposing the inherent male hegemony represented within the play. In addition, by her own account, her reading is also political in that it exposes the ideological discourses which organise the text. She comments that poststructuralist approaches highlight that even highly formalist readings are political, inscribed in the discourses both of the period in which the work was produced and of those in which it is consumed. Newman references Derridas work on racism and in addition to employing deconstructionist discourse his influence can be seen in Newmans design. Recognizing the binary opposition denoted by the polarization of Othellos blackness and Desdemonas whiteness, Newman develops this to assimilate the implied opposition of monstrosity or miscegenation represented by Othello and femininity represented by Desdemona. Deconstructive discourse incorporates the notio n that difference exists both between signified and signifier, and at the same time that the signified defers meaning to the signifier. The role of the literary critic is seen as seeking a slippage in the text, thereby denoting duplicity and revealing how the internal linguistic and thematic rules are inexact. Newman finds this critical slippage in both Rymers Short view of Tragedy (1693) and again in Ridleys criticism 250yrs later, to be the lapse from blackness to femininity. (155) Newmans approach offers new and valuable insights through its address of past criticisms, detailing not only how they relate to the ideology of the time they represent, but also illustrating how criticism in itself can be read to demonstrate new ideas and ways of reading the play. Her analysis however, places its emphasis on the Desdemonas interracial relationship with Othello and how her disobedience to her father and her choice of black man threaten the prevalent white male hegemony. Newman does not address other characters marginalised through class distinctions and gender. One such relationship is that between aristocratic Cassio and the courtesan Bianca. The secret nature of their liaison is both essential to the plot but also preserves Cassios social standing. Cassio treats Bianca with little respect scorning her foolishness in loving him. Cassio, Iago and Brabantio all share a mutual sexist prejudice in a similar way to the racist disdain which shapes their worldview. Othello can be seen to be outside this racial bigotry but Newman does not address the question of whether he accepts the central stereotyped perception of women. Newmans outline of historical womens roles focuses solely on a westernized version of society and does not address the way in which women were historically regarded within non-westernized cultures. Hinging on the underpinning social apprehension with regard to miscegenation, Newmans argument takes it lead from Bennetts notion that the position a text holds within relation to the ideology at its origin is not necessary an indication of the position which it may subsequently come to hold in different historical and political contexts. Some critics however claim Newman is anachronistic, applying modern concepts of racism historically. Shakespearian audiences would have understood race in a totally different way to contemporary audiences. It would then follow that Newmans application of contemporary ideas with regard to other cultural constructs such as gender would be equally out of place. Acknowledging that Shakespeare was certainly subject to the racist, sexist, and colonialist discourses of his time, Newman declares that by making Othello a black man and through Desdemonas love for him, Shakespeare stands in a contestory relation to the hegemonic ideologies of race and gender i n early modern England. Newmans argument is detailed and engages the play against historical points of view, addressing feminist issues and at the same time employing poststructuralist thinking to achieve her goal of establishing a link between femininity and race. Newman sees such strategies of reading as a social responsible in that they illuminate artificial enactment of works which may falsely represent those marginalised groups standing outside culture and simultaneously within it. This representation she sees as being obscured by the immediacy of dramatic performance. Her analysis of Othello is a demonstration of how seamlessly racial attitudes in early English drama where transmitted to viewpoints surrounding gender and sexuality, illustrating how mutually constitutive race, gender, and sexuality can be.

Vasovagal Syncope Essay -- Fainting Medical Health Essays

Vasovagal Syncope My best friend "Dirk" can easily be picked out of a crowd. His 6'7 stature, impressive muscle mass, very blond hair, big blue eyes, and booming voice cause many people to stare at him-once, in Europe, a Japanese couple asked if they could take a picture of him. Addicted to weight lifting and athletics, my friend does not always enjoy admitting that he is a computer engineer-yes, my 22-year-old buddy is still afraid of the geek label. There is something else to which Dirk will not readily admit-he faints at the sight of blood. In fact, many things can trigger his fainting spells: blood, vomit, overheating, etc. Dirk lives next door to my parents; we grew up together. Recently, he and my sister ran over from his house to ours, which is a distance of about 50 feet. My sister had not worn shoes; when they got to our house, they walked through two rooms before Dirk got dizzy. My sister had cut her foot, and the blood that had spread over the tile floor made Dirk turn his head away, and sit down. My mother ran to the rescue-Dirk's, not my sister's. She helped him breath deeply, and luckily he avoided fainting. A few Christmases ago, Dirk caught a stomach virus. He made it to the bathroom just in time, but seconds after vomiting, he fell to the floor, and blocked the door. His parents frantically tried to open the door, they tried to revive him by screaming for probably five minutes, which seemed like an eternity to them at the time. Eventually they revived him. The summer before that Christmas, Dirk was golfing with his high school's golf team on a hot July afternoon. At the end of the course, he and his coach walked to the parking lot. All of a sudden, Dirk toppled like a tree onto th... ...ncope. Perhaps more research will lead to more conclusive knowledge about the condition.

Access the website from your state below and state what steps are required for making a report as a mandatory reporter.(copying and pasting from these sites is not appropriate and may result in a â€Å"Not Competent† result) Remember the following Protective Concerns Are: You are concerned about a child because you have: †¢ A child has disclosed (informed you) that they have been harmed or neglected. †¢ observed the child and seen indications that they are being abused or neglected. †¢ You have been made aware of possible indications of harm due to your involvement within the community outside of your professional role. At all times remember to: †¢always record any of your observations no information is irrelevant †¢ follow appropriate protocols of your centre and also child protection. †¢ consult notes and records †¢ inform and work with other workers that may need to know †¢ inform and work with other agencies if need be. 1. Step One Responding to Concerns  · If concerns are for a child that you believe is in significant risk of harm then you would refer to step four.  · If you believe that a family should be referred to child First then you go to step three  · In all other situations you go to step two 2. Step Two Forming a Belief on Reasonable Grounds  · Think about the level of danger the child may be involved in Is your belief informed that the child is at risk or is in significant danger think yes or no?  · Do you doubt the ability of the parents care toward the child or protection of the child yes or no?  · If yes for the questions you go to step four  · If you have concerns for the child or family refer them to child first if not in significant danger. 3. Step Three Making Referral to Child First  · Contact the local provider for Child First.  · Contact list is usually on department of human services website.  · Have notes with observations of the child and details about the family. 4. Step Four Make a report to Child Protection  · Call your local child protection provider immediately this is usually found on the department of human services website  · For after hours child protection emergency call the emergency line  · Have notes, observations of the child along with details of the family ready with you. Non mandated staff members that believe on â€Å"reasonable grounds† that a child is in dire need of protection are able to report concerns to child protection. 2. Where would you find information on how your service responds to Child Protection Issues? If unsure you can always ask your room leader or centre director to point you in the right direction. You will always find how your service acts and responds to child protection issues within the service policies and procedures and code of ethics. The overall regulations of how the service should respond will be found within the national regulations which is a set of guidelines for services and how they should be run. 3. 3. List the legislative acts that govern Child Protection Services in your state/territory. My state is Victoria and the legislative acts that are in my state are the following Principal Acts:  · Children, Youth and Families Act 2005 (as amended 2011) Other relevant Acts:  · Working with Children Act  · Child Wellbeing and Safety Act 2005  · The Charter of Human Rights and Responsibilities Act 2006  · Family Law Act 1975

Polymerase Chain Reaction (PCR)

Since it's first introduction in the year 1983, Polymerase Chain Reaction (PCR) has very rapidly become a fundamental tool for improving the health and human life. PCR was developed by Dr. Kary Mullis, who was at the time working for Cetus Corporation as a chemist. PCR is the quick and efficient method for making unlimited copies of each and every inch of DNA. It can also be adapted to allow amplification of RNA samples as well as DNA samples from any type of organism. PCR is simplified into a 3-step process, which is repeated for 30-40 cycles. The procedure begins with the first step called denaturation. In the phase of denaturation, the structure of the DNA is altered. The double-stranded DNA melts and exposes into two pieces of single-stranded DNA at approximately 94 degrees Celsius. Transitioning into the second step called annealing or in other words, pairing up together. At a temperature of 54 degrees Celsius, the primers cool down and join to the single-stranded DNA or â€Å"template†. The double-stranded DNA then attaches to the polymerase and starts to shoot out copies. Finally during the last stage of the PCR process known as elongation or extension, the polymerase works it's magic. At 72 degrees Celsius the DNA building blocks are paired up with the DNA primers, to create a double-stranded DNA molecule. After all the processes are completed in one cycle round, a single portion of double-stranded DNA is finally enlarged into two separate pieces of double-stranded DNA. However, as the cycles repeat themselves, more and more clones are generated and the number of DNA copies are intensified exponentially. The procedure of doing a PCR is more vital than we may fathom. It has been found to cure and diagnose genetic diseases, locate bacteria and viruses, DNA fingerprinting, study paternity, biological relationships, and human evolution. All in all, PCR has become widely known to biologists, DNA labs, and many other forensics laboratories. PCR is also one of the quickest testing methods to many diseases, for example The Human Immunodeficiency Virus, commonly known as HIV. HIV is a very difficult disease to find and eradicate. The earlier tests depended on the presence of antibodies in the human bloodstream. When performing the antibody test, there may be no results until weeks after exposure to the virus. Nevertheless, when performing a PCR test results appear much faster, and as little as one genome among 50,000 host cells can be easily detected. PCR can efficiently detect the forensics of HIV, rather than the antibodies contained in the blood. The same goes for Tuberculosis, which are also complicated in sampling from patients, PCR tests speed up the results so that precautions may be taken as soon as possible. PCR testing is one of the many ways that can assist in detecting several diseases, and yet PCR is very vital to the human life.
