Identification of unknown Bacteria Research Paper

Identification of unknown Bacteria - Research Paper Example With regards to the aim of the experiment, which is to identify unknown bacteria from mixed culture #18 using biochemical and morphological test, the two organisms identified had distinct characteristics which were looked for following laboratory tests. Normally, Gram staining is employed to differentiate 2 bacteria groups with different cell wall constituent. The method has the ability to differentiate Gram negative and Gram positive bacteria group; thus the bacterial cells are either colored red or violet. Gram positive bacteria is shown by Violet staining due to a thick layer of peptidoglycan existing   in the cell wall of the bacteria, thus the crystal violet is retained by these cells on a slide. Consequently, Gram negative bacteria is shown by red staining due to a thin layer of peptidoglycan existing in the bacteria cell wall, hence crystal violet is not retained   by bacterial cells. (Winn et al,2006)MacConkey Agar is used to distinguish Gram- negative, lactose-fermenting organisms from organisms that are non-fermentative .It is an inhibitory and differential medium that contains Crystal violets, bile salts, inhibitory agent and neutral red. Neutral red acts as a pH indicator.   Klebsiella pneumoniae bacteria is known to be lactose fermenters hence unknown A while Salmonella Typhimurium bacteria is not lactose fermentor thus unknown B. The orinithine decarboxylase test is important for Enterobacteriaceae differentiation. (MacFaddin, 2000). MR-VP broth for Methyl Red test consists of peptone, phosphate buffer and glucose.

Natural Selection through Competition and Isolation of Species Essay Example for Free

Natural Selection through Competition and Isolation of Species Essay The struggle for life results in differences in form which Darwin called â€Å"incipient species. † Darwin says that variations, no matter how small or big they are, will necessarily be passed down to offsprings because they will tend to make those individuals survive. He called this process natural selection to relate it to mans ability to select objects in their lives. Herbert Spencer, an English philosopher, had previously described the struggle for life as the â€Å"survival of the fittest,† which Darwin though was also appropriate for the process of evolution that goes on among organisms. Competition is constantly happening between organisms because of the rate of population increase. This leads into a Malthusian struggle that eliminates the nonadaptive individuals from the group (Cuvier et al. , 2003, p. 20). The divergence in the forms of species may result from changes in living conditions. Darwin pointed out that some species may be wiped out because of the immigration of other groups more adapted to the environment where they live in. Man-induced selection practiced by breeders of animals often results in sharp cases of divergence within species, although this is also possible through natural processes (Cuvier et al. , 2003, p. 24). Some experts point out that Darwin anticipated the concept of â€Å"ecological niche† because he suggested that all individuals who survive in the environment were not necessarily higher or better. They just have their own features that made them better adapted to the environment. According to Darwin, natural selection is facilitated by the isolation or seclusion of a population of organisms. Its pace can also quicken if the species is composed of a large population in open areas, since this indicates that there are many variations within the group (Cuvier et al. , 2003, p. 26). Darwin measured and described the divergence in species through a tree diagram with branches that stopped or fell off while extinction happens. New buds also spring from the tree to symbolize new species, leading to Darwin call it the â€Å"tree of life. † Heredity in Darwins Theory of Natural Selection Evolution had already been discussed before Darwins theory was published. Darwin only added substance to the science of evolution by proposing the idea of natural selection as a tool of evolution. Despite the soundness of his theory however, it was still difficult to form a coherent story of the evolution of organisms because there was no acceptable model or standard of heredity to explain natural selection. In fact, Darwin admits that the laws of heredity are still unclear (Endler Endler, 1986, p. 36). Since there was no guiding standard for heredity, Darwin borrowed Lamarck’s idea of acquired characteristics through use and disuse. He believed that when animals regularly use certain parts of their body, those parts become stronger or larger. In contrast, disuse results in certain parts being weaker or decreasing in size. These acquired characteristics are then passed on to newer generations either through domestication or through nature. While use and disuse had some role in evolution, Darwin said that some developments in the characteristics of animals, such as the loss of wings of some insects, might have resulted from natural selection.

The Family Circuit Essay -- Technology Computers Entertainment Papers

The Family Circuit A mother is doing laundry while her infant sleeps soundly in the room upstairs. She is mid-fold when a cry pierces the silence. She looks over at the baby-cam monitor and sees that her child is in his crib. She reads the dials on the side of the monitor: Vital Signs: normal. Diaper moisture level: 0. Minutes since last feeding: 136. Sighing, she reaches over and clicks three buttons, and resumes her work. Upstairs the crib starts to rock gently, as a nearby stereo plays a recording of his mother's voice singing, and a mechanical arm holding a bottle reaches in and holds the bottle for the baby to grasp. The machine retreats and the baby is lulled back into slumber without his mother having to move an inch or touch him. The scenario may seem exaggerated—unlikely in our own time, yet not unforeseeable in the future. Our era has become so obsessed with technology and its time-saving wonders that quality time itself is taking a backseat to efficiency, destroying what is essentially the human experience. Time used to be the feature by which a family's strength was measured: the more time you spent with your children, the closer you were. Families once gathered around a dinner table in talkative interaction. But now dinner conversation is being silenced as technology takes a permanent seat at the American family's dinner table. There is no age or gender group excluded from the target practice of the technology market. Everyone from infants to grandparents is not only involved, but subject to the increasing dependency on technology to keep family life running smoothly. The once low-cost "quality family time" has given way to a thousand-dollar cycle of expenses to keep every member of the family in touch and up... ..." New York Times. February 10, 2001.

Teachers and Technology Essays -- Education, Technology in the Classro

Nature of the Study Teachers' overall attitudes towards technology play a vital role in adopting a set method in determining how to instruct with wireless laptops (Kervin & Mantei, 2010). Alternatively, the way teachers perceive technology will hypothesize a key determinant of the nature of this quantitative, pre-experimental study. In this study, the reason why teachers do not routinely and effectively use available technology such as wireless laptops in K–12 classrooms will be examined. To take full advantage of technology, while reducing possible drawbacks, requires matching the technology with the learning objectives (Lee, 2010). The researcher will use a pre-experimental, quantitative study, which has a cross-sectional web-based, five point Likert-scale survey entitled the Technology Attitude Scale (TAS). The TAS will be administered to collect data during the course of this study. Subsequently, the TAS questionnaire is an adapted version of Swan and Dixon’s (2006) model. The results of the TAS will be analyzed using an experimental and non experimental sample to establish teachers’ attitudes about wireless technology in the instructional practice. The survey provides and shows the reliability of .92 and showed a proven validity tested through statistical analysis. Swan and Dixon (2006) used the TAS to examine any correlation between teachers’ attitudes towards technology and the use of such technology in their study. In this study, a convenience sample instead of a random sample of teachers in a rural southeast Georgia school district will be used because teachers are both accessible and willing to participate.

Pilgrimage Toward Social Equality

The Emancipation Proclamation of 1863 declaring African’s freedom from slavery and officially making them part of the United States was mandated a century prior to Martin Luther King Jr’s historical speech calling for social justice and abolition of racial discrimination against African Americans. Between the two historical periods, the black communities all over America have suffered subtle and savage forms of discrimination and oppression from the whites. The black community strived to seal their place in society amidst hostility and negative criticisms.One short story that very well illustrates their struggles is Ralph Ellison’s Battle Royal. The story provides a very descriptive narration of a black man’s pilgrimage to overcome oppression from an overly-racist community ruled by the economically-powerful white men and to find his opportunity to shape the destiny of his people. This paper aims to provide a vivid presentation of inhumane and savage oppre ssion that the African Americans encountered in Southern America before gaining their voice and place in American society.Battle Royal was narrated in a first-person perspective with a nameless narrator. He suggests that twenty years back, he has been struggling to find his own identity through other people’s acceptance and affirmation. He further explained that his dilemma for self discovery rooted from his grandfather’s last words on his deathbed, â€Å"Live with your head in the lion’s mouth. I want you to overcome ‘em, with yeses, undermine ‘em with grins, agree ‘em to death and destruction. Let ‘em swoller you till they vomit or bust wide open.† (Ellison, 2000, p 935) He calls his grandfather’s lines a â€Å"curse† haunting him whenever he feels accepted as the narrator describes, â€Å"When I was praised for my conduct, I felt a guilt that in some way, I was doing something that was really against the wishes of the white folks, that if they had understood they would have desired me to act just the opposite, that I should have been sulky and mean, and that they really would have been what they wanted, even though they were fooled and thought they wanted me to act as I did.†(Ellison, 936) The narrator’s statement represents his mindset of his actions and attitude toward the white folks. His current partially confused mindset is influenced by his grandfather’s words. In layman’s term, his grandfather’s words can be translated to a call to action to fight a good fight by acting according to the opponent’s will until they take you all in with acceptance until they destruct themselves in their own volition.One such incident where the orator became accepted and triumphant is when he delivered a graduation speech, which he describes by saying, â€Å"On my graduation day I delivered an oration in which I showed that humility was the secret, indeed, the ver y essence of progress. (Not that I believed this — how could I, remembering my grandfather? — I only believed that it worked)† (Ellison 938). His speech received accolades from his professors that he was given the opportunity to deliver it again in a â€Å"gathering of the town’s most leading white citizens†.When he arrived at the venue where he was supposed to deliver his speech, he was informed that before delivering his speech, he needs to join the Battle Royal. The hotel he’s in at that moment was indeed full of economically powerful people all dressed up with their tuxedos, intoxicating themselves with whiskey, and getting themselves a good spot among the chairs neatly lined up along the three corners of the ring. Inside the ring, a pool of black men were lined up blindfolded and were forced to do engage in a violent boxing war against each other.After torturous moments of fighting like headless chickens on the ring, the narrator was abl e to see slightly behind his blindfold. His awareness enabled him to keep a good fight without drawing attention to himself so the white men wouldn’t notice that he’s starting to dodge his hits. In the end of the first round, the narrator remained on the ring together with the biggest boy in the group to fight. While they were fighting it out on the ring, the narrator tried to negotiate with his opponent by scripting the fight and he’ll give him a proportion of the winning pot.His opponent refused and they continued to fight until the narrator was knocked out. Allegorically, the narrator’s unexpected battle before delivering his speech is a symbolic representation of the African American’s years of pains and struggles before they were given the chance to be heard. The battle royal may well represent the fights that black men wage against each other just to gain money, position, and prominence, as is the case of the narrator’s opponent.The co ncept of the fighters blindfolded can be allusion to some of the black men’s blindness of allowing the economically powerful white men to use them as a means of entertainment as if they were freaks of nature. After the first round, the fighters were then called out again for another round of activity where they were attracted to scourge over gold coins and bills scattered in a rug. They urged the fighters to gather the coins for themselves saying it’s all good â€Å"American cash†. In the process, they soon discovered that the rug was electrified.This narration emphasized the white men’s racism through barbaric treatment to the black men, as they treat them like animals. When the show ended, all the participants were paid and the narrator was about to leave the nightmare when the MC called him back to deliver his speech in the congregation of intoxicated people who have earlier gained pleasure through his pains. The narrator proceeded to deliver his Booke r T. Washington inspired speech while trying to conceal his aching physique while gulping down his blood.The narrator described that his audience continued with their incessant chatting and laughter as he delivers his speech and though he was tempted to do something else, the presence of the school superintendent who is still closely listening to him kept him going. In the process of his oration and swallowing his own blood, the narrator accidentally yelled â€Å"social equality†, a phrase had â€Å"often seen denounced in newspaper editorials, heard debated in public. † (Ellison, 940)Upon uttering the word, a deep silenced covered the whole room and the narrator received hostile reactions from his intoxicated audience, until a mustached man asked him upfront what he just said, and he got the chance to correct himself. The interrogator then asked him if he’s not being smart and that social equality was indeed a mistake. The narrator nodded and the man dropped th is statement, â€Å"We mean to do right by you, but you’ve got to know your place at all times. † (Ellison, 944)This man’s powerful statement is a general representation of the white men’s attitude towards racism over the negroes. They are aware of such discrimination, but they gain pleasure in treating them as inferior human beings as it constantly feeds them the feeling of superiority and power. The man’s statement may mean well as to change the narrator’s current status but he commands him to keep his head and mouth in its’ proper place. Upon the end of his speech, he was greeted with applauses as if the entire audience listened with so much enthusiasm to his speech.The school superintendent then came up to the stage to present him with a gift- a scholarship to the State College of Negroes. He then turned to the narrator and addressed him, â€Å"Prize it. Keep developing as you are and someday, it will be filled with important pap ers that will help shape the destiny of your people. † (Ellison, 947) The scholarship the narrator received is a symbol of an opportunity presented to him to â€Å"shape the destiny of his people†. That by going to college, he might become more knowledgeable and able so as to create a better society for his people.The scholarship becomes the first step to his pilgrimage towards social equality. Battle Royal is a very compelling short story that Ralph Ellison eventually made it the first chapter of his greatly-acclaimed novel, the â€Å"Invisible Man†. Every black man in that horrifying period might have been represented by the nameless narrator and all the pain he was inflicted during the Battle Royal is a representation of every black man’s pain and struggle for years.If the readers at that period view it as an allegory to the harsh conditions of the African American people within the American society, it would have been a wakeup call to those who were op pressed to unite and to those oppressors to change the society.

Maltrato(General) Essays - Abraham Senior, Castilians, Free Essays

Maltrato(General) Essays - Abraham Senior, Castilians, Free Essays Maltrato(General) Yo voy a empezar explicando sobre el tema del maltrato a nios y adolecentes. Hay muchos actos violentos cometidos en el hogar entre miembros de una familia. En la dcada de 1970 las feministas analizaron el alcance de la violencia intrafamiliar (considerada como un fenmeno exclusivamente masculino) y se crearon centros de acogida y de ayuda para las mujeres maltratadas y para sus hijos. El trmino maltrato infantil abarca una amplia gama de acciones que causan dao fsico, emocional o mental en nios de cualquier edad. Sin embargo, el tipo de maltrato infligido vara con la edad del nio. Los malos tratos en bebs y nios en edad preescolar suelen producir fracturas, quemaduras y heridas intencionadas. En casi todos los casos de acoso sexual el agresor suele ser un hombre y la vctima una nia en edad escolar o adolescente. Sin embargo, en los ltimos tiempos est aumentando el nmero de nios varones en edad preescolar que sufren este tipo de maltrato. lo largo de la historia, el patriarcado, segn el movimiento feminista, ha puesto el poder en manos de maridos y padres en cualquier relacin conyugal o de pareja. El suttee entre los hindes (que exige que la viuda se ofrezca en la pira funeraria de su marido), el infanticidio femenino en la cultura china e india dominadas por hombres, los matrimonios concertados entre los musulmanes, que pueden llevar al asesinato o a la tortura de la mujer, y la esclavitud domstica en el nuevo hogar indican la presencia endmica de sexismo y violencia intrafamiliar masculina. Se desconoce si este tipo de violencia es un fenmeno en alza o en baja, incluso en pases donde hoy existe un mayor nmero de denuncias y de registros que en pocas anteriores. Por un lado, es probable que haya una mayor predisposicin a denunciar estos hechos al existir una mayor independencia femenina, ms oportunidades de trabajo fuera del hogar, mayor conciencia feminista y ms posibilidades de anticoncepcin. Por otro lado, la motivacin para la violencia es menor al existir una mayor libertad de eleccin de compaero, menos matrimonios forzados y una mayor emancipacin de la mujer en cuanto a propiedad, estudios y divorcio. Ninguno de estos elementos puede ser evaluado con exactitud. La tecnologa de la informacin actual ayuda a recopilar datos, pero en cambio resulta difcil conocer los procesos y los antecedentes. Algunas feministas radicales opinan que es la familia la raz del problema y que la solucin est en liberarse del hombre, mientras que en el extremo opuesto otros opinan que la mu jer debe limitarse a su papel de ama de casa y madre. Aunque no puede afirmarse que toda la violencia sea cometida por hombres, s ocurre as en la mayora de los casos. A veces son el padre y la madre juntos quienes cometen las agresiones, como en el caso de malos tratos a los hijos. La patologa del maltrato infantil, desgraciadamente, no tiene fin.

Our genes and enviromental factors influences our health essays

Our genes and enviromental factors influences our health essays Our genes makes us unique and they influence our personality. People born with certain traits can deal with stress and emotions better than people that lack that trait. For example a person born with the trait of calmness can deal with stressful situations better than a person born with the trait of nervousness can. The body and mind is one. What happens to one affects the other. It has been know that people who manage stress better usually have better health. Good health is an important aspect of quality of life. Healthier people are also happier, more socially active, and more satisfied with life. The genes is the only factors that makes individuals unique and we have no control over our genetic make up, but our environment can dramatically influence our personality and over all health. Given a perfect environment (what ever might be) humans might live happier for a very long time. The relative impact of genes and environment can be assessed by studying twins as well as by looking at the longevity of immediate ancestors. I read an article an MSN that deal with the notion of genes vs environment. The article was about a major study of identical twins and fraternal twins. The study was to see whether the twins died closely together. If those with the same genes died closely together while those with different genes did not, then that would support a genetic influence. The influence of the environment is assessed by comparing those living under the same and different environment. If those from the same environment died close together while those from different environments did not, then that would support an environmental influence. The finding of the study suggest that longevity is largely determined by environmental factors with 66% variance due to environment an 34% due to genetics. Hmmm! Well, all I can say is that gender, race are genetic factors are beyond our control but the environmental factors can shape t...

Best Crucible Act 2 Summary

Best Crucible Act 2 Summary SAT / ACT Prep Online Guides and Tips Act 2 of The Crucible takes us to the Proctor household, where we learn just how crazy things have gotten in Salem after the initial flood of accusations. We'll also find out the extent to which John Proctor's relationship with Elizabeth has suffered after his affair. By the end of Act 2, characters who were thought to be beyond reproach will find themselves in mortal peril as a result of unchecked hysteria. I'll provide two different summaries. The first is a short summary intended for quick review of the plot, and the second is a long summary (the "oops I didn't read it" summary) for those of you who want more specific details on exactly what happened, including smaller side conversations and minor plot points. The CrucibleAct 2 Summary - Short Version John and Elizabeth discuss the trials in Salem, and they both realize things are getting out of hand (though John still believes the court would never actually hang anyone). Elizabeth tells John he has to go into town and inform them that Abigail is lying. John’s hesitance leads to an argument rooted in his affair and the lack of trust that continues to pervade their marriage. Mary Warren, who went to Salem to testify against the Proctors’ wishes, returns to the house and gives Elizabeth a poppet (doll) she made in court. Mary reveals that Elizabeth was accused in court, but she spoke up in her defense. It’s clear that Abigail is accusing Elizabeth because she hopes to take her place as John Proctor’s wife. This leads to another argument where Elizabeth urges John to tell Abigail that there’s absolutely no possibility of them ever being together. Hale arrives and questions the Proctors about their religious devotion based on the accusations levied against Elizabeth. John tells him that the girls are frauds, and Hale actually starts to doubt the validity of the accusers’ claims. Giles Corey and Francis Nurse come to the house in distress, revealing that both of their wives have been arrested for witchcraft. Then, Ezekiel Cheever and Marshal Herrick arrive with a warrant for Elizabeth’s arrest. They find the doll that Mary gave her and notice that it has a needle stuck in it. This matches up with the â€Å"attack† on Abigail allegedly perpetrated by Elizabeth’s spirit. Proctor gets Mary to tell the truth about the doll. She says that she made it in court and stuck the needle in herself with Abigail sitting right next to her. However, the authorities are not convinced by this story. Proctor tears up the arrest warrant in frustration, but Elizabeth agrees to go peacefully. When everyone else has left, Proctor tells Mary that she must testify on Elizabeth’s behalf in court. Mary is terrified to do this because she knows that Abigail will turn the rest of the court against her. Proctor begins to feel a sort of relief because he senses that he and all the other hypocrites are finally being punished for their sins. Judgment, both internal and external, is a constant throughout The Crucible. The CrucibleAct 2 Summary - â€Å"Oops, I Didn’t Read It† Version Act 2 takes place at the Proctor household eight days after Act 1.Elizabeth Proctor serves John dinner, and they chat about his day.There’s some tension between them because of the lingering effects of John’s affair with Abigail. Elizabeth says that Mary Warren went to Salem that day, and John is angry because he forbid her to go.Elizabeth claims she tried to stop her, but Mary insisted on participating in the court proceedings. Elizabeth then reveals the full extent of the situation in Salem to John.Four judges have been summoned from Boston to preside over the trials, and fourteen people are jailed on accusations of witchcraft.Abigail has been exercising a great deal of power in court and continues to feign being attacked by witches.Elizabeth says John must go to Salem to tell the court that Abigail is a fraud.He has some reservations because it will be his word against hers.She thinks he wouldn’t be so hesitant to do this if he had to discredit a different girl.John gets angry that Elizabeth still won’t fully trust him around Abigail, and he feels liks he's always being judged.Elizabeth points out that it’s really his internal guilt about the affair that's making him feel judged. At this point, Mary arrives back from Salem appearing drained from the day’s proceedings.She gives Elizabeth a poppet (a rag doll, essentially) that she made in court.Mary tells the Proctors that there are now 39 people arrested.She breaks down and starts crying.Mary reveals that Goody Osburn is set to hang, but Sarah Good confessed, so she will live.Mary is genuinely convinced that Sarah Good tried to kill her by sending out her spirit.She then claims to remember other times that she was bewitched by Sarah Good.Sarah Good was ultimately condemned after being unable to recite her commandments. Mary insists on going back to court the next day because she feels that she’s doing God's work. JohnProctor tries to whip Mary for her insolence, but Mary interjects that she saved Elizabeth’s life by defending her against accusations in court.Proctor dismisses Mary.After this, Elizabeth is pretty sure that Abigail wants her dead.She thinks Abigail is trying to take her place as Proctor’s wife and will continue to accuse her until she is arrested.Proctor tries to allay these suspicions even though he knows that she’s probably right. Elizabeth insists that John go to Abigail and tell her explicitly that there is no possibility of them ever being together in the future.John gets angry (again) that Elizabeth presumes that he’s still attached to Abigail and is leading her on in some way. At this point, Reverend Hale arrives at the house to speak with the Proctors about the accusations made against Elizabeth.He has just come from questioning Rebecca Nurse, who was accused despite her solid reputation in town.Hale asks why John doesn’t go to church often, and he says it’s because his wife has been sick and he dislikes Parris’ displays of materialism.Hale asks Proctor to say his commandments, and, ironically, the only one he forgets is adultery.Hale is not satisfied. Elizabeth insists that John tell Hale that the girls are faking.After hearing what Proctor has to say, Hale starts to doubt the accusers as well.Still, Proctor balks at testifying in court because the atmosphere sounds so hysterical ("I falter nothing, but I may wonder if my story will be credited in such a court." pg. 65).Elizabeth says she actually doesn’t believe in witches at all, and Hale is taken aback because witches are specifically mentioned in the Bible. Giles Corey enters the house accompanied by Francis Nurse.They reveal to Hale and the Proctors that their wives have been arrested and sent to jail.Rebecca Nurse is suspected of murdering Ann Putnam’s babies.Hale says if Rebecca Nurse has fallen under the control of the Devil, no one is safe.Corey now realizes he made a mistake by voicing his suspicions about his wife’s reading habits in the previous act.The man who accused Martha Corey bought a pig from her that died soon after.He was bitter that Martha wouldn’t refund him the money, so to get revenge he accused her of casting spells with her books. Ezekiel Cheever and Marshal Herrick then arrive at the house.They have a warrant for Elizabeth Proctor’s arrest, and they confirm that she was accused by Abigail.Cheever orders Elizabeth to hand over any dolls she has in the house.Elizabeth is confused and says she hasn’t had dolls since she was a kid.She forgot about the one Mary gave her earlier, which Cheever sees and examines.John Proctor tells Elizabeth to go get Mary so she can confirm that the doll was a gift.Cheever finds a needle in the doll, which he takes as proof of Elizabeth’s guilt.Abigail fell on the floor screaming at dinner andpulled a needle out of her stomach, claiming that Elizabeth’s familiar spirit stabbed her. Mary and Elizabeth return, and Mary admits she made the doll in court while Abigail was sitting next to her.John Proctor thinks that this makes it pretty clear that Abigail is lying, but it’s not enough for Hale to discount the â€Å"proof.†Hale warns Mary that she’s making severe accusations against Abigail. Proctor is fed up with the court’s blind trust in Abigail and the other accusers.He rips up the arrest warrant and tells everyone to leave. Elizabeth sees that there is no way out of the current situation and agrees to go with the marshal to avoid a scene.John promises to bring her back soon and calls Hale a coward for being too passive about the situation.Hale counsels patience and reason so that they can get to the bottom of what’s really happening. Everyone exits the house except Mary and John Proctor.Proctor tells Mary she must testify in court about the real story behind the doll.She is concerned about Abigail’s potential reaction.Mary knows about the affair, and she thinks Abigail will come clean about it and ruin Proctor’s reputation if Mary tries to discredit her. Mary also believes that the court will turn against her if she tells the truth.Proctor is adamant that Elizabeth will not die for his mistakeswith Abigail and starts getting aggressive with Mary to scare her into telling the truth.Mary continues to insist that she can’t testify because of the potential consequences. Does your target always get stabbed with the same implement that you used to poke the voodoo doll? And does that mean you can only use voodoo dolls to give people you hate superficial puncture wounds? Luckily for Abigail, no one is in the right state of mind to care about how little sense all of this makes. The CrucibleAct 2 Quotes This section lists themost important quotes in Act 2. I've written short explanations for each that elaborate on their significance. â€Å"I have not moved from there to there without I think to please you, and still an everlasting funeral marches round your heart. I cannot speak but I am doubted, every moment judged for lies,as though I come into a court when I come into this house!† (John Proctor pg. 52) In this quote, John Proctor criticizes his wife for continuing to mistrust him after he ended things with Abigail.He claims that â€Å"an everlasting funeral marches round [her] heart,† meaning that she insists on continuing to mourn for the damage the affair did to their relationship rather than allowing him to repair it. He feels that Elizabeth is constantly suspicious of him now, to the point where he can’t do anything without being judged.In fact, Elizabeth doesn’t show many signs of being overly judgmental of John (she’s actually doing pretty well considering he just had an affair with a teenager), and most of these issues are a projection of his own guilt. â€Å"I do not judge you. The magistrate sits in your heart that judges you.† (Elizabeth Proctor pg. 52) The real court in Salem is mirrored by a metaphorical court within the mind of John Proctor. Here,Elizabeth points out that John is his own harshest judge.If anyone is judging him, it’s a mini-John Proctor with a judge wig banging a tiny gavel right on his heart strings.Since he's unable to forgive himself for the affair, he projects his guilt onto her even when she’s not acting particularly judgmental. â€Å"I am amazed you do not see what weighty work we do.† (Mary Warren pg. 56) Mary uses â€Å"weighty† as a synonym for â€Å"important† or â€Å"vital.† She feels that she’s doing God’s work, and she is given a sense of purpose and duty through her participation in the trials.In a sense, the trials really are â€Å"weighty work† because they overhaul the entire community.They provide an outlet for the repressed resentments and jealousies that were simmering under the surface. â€Å"Theology, sir, is a fortress; no crack in the fortress may be accounted small.† (Reverend Hale pg. 64) This quote from Hale is a testament to the power of the church in this community and the perception of religion at the time.There is an â€Å"either you’re with us or you’re against us† mentality that encourages persecution of anyone who deviates even slightly from accepted Christian behavior.One misstep can derail a reputation completely, so everyone is eager to conform out of concerns for self-preservation. â€Å"There is a misty plot afoot so subtle we should be criminal to cling to old respects and ancient friendships. I have seen too many frightful proofs in court - the Devil is alive in Salem, and we dare not quail to follow wherever the accusing finger points!† (Reverend Hale pg. 68) This quote from Hale sums up the atmosphere of hysteria that has emerged in Salem.Everyone is afraid to question any of the accusers because that might mean falling for the Devil’s tricks.They feel that the consequences of doubting these accusations could be more dire than the risk of having some innocent people caught up in the mix.Reputation has been conquered by paranoia. Both Parris and Hale will cite different theological examples over the course of the play where someone who was once thought to be virtuous turned out to be evil.In this case, it’s â€Å"Man, remember, until an hour before the Devil fell, God thought him beautiful in Heaven† (Reverend Hale pg. 68).In the next act, Parris will say â€Å"You should surely know that Cain were an upright man, and yet he did kill Abel† (Reverend Parris pg. 85).On some occasions in the Bible, people who were thought to be good turned out to be bad. This shaky precedent is extrapolated to the current situation and gives the church leaders reason to mistrust even the most well-reputed citizens of Salem. â€Å"Why do you never wonder if Parris be innocent, or Abigail? Is the accuser always holy now? Were they born this morning as clean as God’s fingers? I’ll tell you what’s walking Salem - vengeance is walking Salem. We are what we always were in Salem, but now the little crazy children are jangling the keys of the kingdom, and common vengeance writes the law!† (John Proctor pg. 73) John is incredibly frustrated because the accusers are all taken at their word, and the accused are denied a fair opportunity to defend themselves.He points out that many of these accusations are clearly driven by revenge.Though that desire for vengeance was always there within the people of Salem, it has only now begun to affect judicial processes and societal power structures in dramatic ways.â€Å"The little crazy children† are the accusers, mostly teenage girls who previously had no power in Salem. They are now â€Å"jangling the keys of the kingdom,† or testing their ability to provoke widespread chaos that favors their own agendas. â€Å"Now Hell and heaven grapple on our backs, and all our old pretense is ripped away - make your peace!Peace. It is a providence, and no great change; we are only what we always were, but naked now.† (John Proctor pg. 76) This an aside John makes to himself at the end of Act 2. He views the witch trials as an unveiling of the true nature of the people of Salem.No one has suddenly become vengeful, paranoid, and unjust - they were always like this underneath a shallow layer of decorum.Proctor has also been burdened by the secret of his affair with Abigail and the guilt he has about it.He sees himself as an immoral person, and he is relieved in a certain sense that he’s about to be exposed for the hypocrite he is so his sins will stop eating him up inside. John was referring to his two cats, Heaven and Hell. Metaphorical pet names were all the rage in 17th century New England. The CrucibleAct 2 Thematic Analysis This is a brief analysis of the most prevalent themes in Act 2. I'll come out with a more comprehensive thematic analysis for the whole play very soon! Irony This act sees one of the most blatant examples of irony in the play. When John is asked to recite the ten commandments, the only one he forgets is the one most applicable to him, adultery (â€Å"Thou shalt not covet thy neighbor’s wife."). This shows how hard John is trying to repress his guilt. He hopes to leave the affair in the past and pretend it never happened, but he can't ignore the impact it has had on his relationship with Elizabeth, his sense of self-worth, and Abigail's psyche. Hysteria Act II is when the full extent of the hysteriainSalem becomes apparent.Mary says that there are now not 14 but 39 people who have been thrown in jail on suspicion of witchcraft.The hysteria has been heightened by several confessions which seem to confirm the existence of an evil witchy plot.People are told they will be executed if they refuse to confess, so obviously false confessions abound. The authorities and citizens of the town are so scared of the possibility that these coerced confessions could be the truth that they ignore any logical objections to the proceedings ("I have seen too many frightful proofs in court - the Devil is alive in Salem, and we dare not quail to follow wherever the accusing finger points!" Hale pg. 68).They instead continue to push for more confessions, which are then counted as â€Å"evidence† of a grand Satanic plot.Anyone who doubts the existence of this plot is brought under suspicion. When the poppet is discovered in Elizabeth’s possession, it is taken as concrete proof that she’s involved in witchcraft. Elizabeth'sside of the story immediately becomes virtually irrelevant because Abigail’s testimony is much scarier and more dramatic: "She sat to dinner in Reverend Parris's house tonight, and without word nor warnin' she falls to the floor. Like a struck beast, he says, and screamed a scream that a bull would weep to hear. And he goes to save her, and, stuck two inches in the flesh of her belly, he draw a needle out." (Cheever pg. 71). The idea that a witch's familiar spirit could be going around stabbing people willy-nilly is too horrifying for people who genuinely believe in witchcraft to give Elizabeth the benefit of the doubt. Everyone severely underestimates Abigail's ambition and deviousness. Reputation Goody Good, an old beggar woman, is one of the first to be accused because she is already held in such low regard. It’s easy for respectable citizens to accept that she’s in league with the Devil because she is an "other" in Salem, just like Tituba.Elizabeth knows that Abigail has it in for her because there's no other reason she would take the risk of accusing a farmer’s wife with a solid reputation.Elizabeth is an upstanding member of the community, whereas other women who have been accused were already at the bottom of the totem pole. Elizabeth knows that her high status still affords her some credibility, but this is the point at which the value of reputation in Salem starts to butt heads with the power of hysteria and fear to sway people’s opinions (and vengeance to dictate their actions).In this act it is also revealed that Rebecca Nurse has been accused, a woman whose character was previously thought to be unimpeachable. This is taken as evidence that things are really getting out of control ("if Rebecca Nurse be tainted, then nothing's left to stop the whole green world from burning." Hale pg. 67) , but still people hesitate to discredit the accusers out of fear for their own reputations. Power and Authority In Act 2, we see that Mary Warren has been given a new sense of her own power through the value placed on her testimony in court. Elizabeth notes that Mary's demeanor, previously very meek, is now like that of â€Å"the daughter of a prince† (pg. 50). Mary has never felt like she was a part of something significant like this before, which likely adds to her conviction that the people she's accusing are truly witches. Mary and the other girls are riding on a high of attention and respect from powerful people in the community, so they are especially motivated to stick to their stories (and even genuinely believe their own lies). At this point, Abigail has gone from a nobody to (unofficially) one of the most powerful people in Salem. It would be incredibly difficult for her to go back on her accusations now. Abigail’s low status in normal times ironically gives her a great deal of power in her current situation. No one thinks she’s smart or devious enough to make up all these insane stories, so she is taken at her word. In the words ofJohn Proctor, â€Å"the little crazy children are jangling the keys of the kingdom† (pg. 73). Guilt This themeisprominent in the dynamic between John and Elizabeth. John is frustrated with Elizabeth because she still doesn’t fully trust him, but he’s really projecting his internal guilt about his affair with Abigail onto her. John gets worked up because he’s angry at himself for essentially setting these accusations in motion against his wife.He’s frustrated that he hasn’t been allowed to leave the affair behind him and hates that he now has to face up to real consequences.He underestimated Abigail and is now paying the price.John’s guilt is a huge thematic undercurrent throughout the play, as we will see to an even greater extent in the next two acts. Even before his arrest (spoiler alert), John is a prisoner of his own guilt. He kinda deserves it, tbh. The CrucibleAct 2 SummaryConclusion In Act 2, the situation in Salem goes from worrisome to straight up horrifying. It becomes clear just how far the characters are willing to go to protect themselves against the town's burgeoning hysteria (even if it means setting others on a path to the gallows). Let's recap the most important events: Elizabeth informs John that more people have been arrested, and he needs to go to Salem to tell the court that Abigail is a fraud. Mary returns from Salem after participating in the trials and gives Elizabeth a ragdoll she made in court. Mary tells the Proctors that Elizabeth was mentioned briefly, but the accusations were dismissed thanks to Mary's favorable testimony. Elizabeth knows Abigail will continue to accuse her until something sticks, and she tells John he has to go directly to Abigail and tell her that they're NEVER gonna be a thing. Hale warily questions the Proctors about their skimpy church attendance, and John tells him Abigail is a fraud. Hale has fleeting doubts about the legitimacy of the girls' accusations. Francis Nurse and Giles Corey come to the house and say that their wives have been arrested. Then, Ezekiel Cheever and Marshal Herrick arrive with a warrant for Elizabeth's arrest. They find a needle in the doll Mary gave Elizabeth that corresponds to the needle that Elizabeth's familiar spirit supposedly used to stab Abigail. Elizabeth goes with them peacefully after realizing she can't prove her innocence. John angrily insists that Mary must tell the court Abigail is lying. Mary says she's too scared of the consequences and doesn't think she can do it. This is all a set-up for the heightened drama of Act 3. John Proctor is prepared to tell the whole truth about Abigail to save his wife and the rest of the accused, but will that be enough to stem the tide of witch-related hysteria? Hint: no. What's Next?

Steam Reforming and the Production of Hydrogen Gas Essay

Steam Reforming and the Production of Hydrogen Gas - Essay Example About 50% of the global production of Hydrogen is produced by this process(www.getenergysmart.org/Files). eg. activated carbon filters, pressurisation and depending on the reformer design, either pre heated and mixed with processed steam or directly injected with the water into the reformer without the need for an external heat exchanger. The water is normally demineralised using appropriate water conditioning systems. Two options are available for reforming one option is high pressure reforming at a working pressure upto 16 bar. The other option is to use low pressures (1.5 bar) with increased conversion ratios (www.global-hydrogn-beus-platform.com). 2.2 Steam Methane Reforming: The process involves the use of high temperature steam (700C) which is reacted with natural gas( primarily methane) to produce Hydrogen. Methane reacts with steam under 3- 25 bar pressure in the presence of a catalyst to produce Hydrogen, Carbon Monoxide and a relatively small amount of Carbon Dioxide. This process is endothermic and hence heat must be supplied to the process to proceed. (www1.eere.energy.gov) The methane steam reforming reaction is endothermic. Hence this reaction requires a high process temperature to proceed. As the number of moles also changes for the reaction, the reaction is facilitated by as low a pressure as possible to maximise the Methane conversion rate. Another way to shift the equilibrium to the right side is to increase the ratio of steam to methane. Overall, the conversion rate of methane is a function of pressure, temperature and steam/ Methane ratio. The reformer reactor consists of catalyst filled tubes surrounded by a fire box that provides the heat for the reaction as shown in the process flow diagram ( Fig.3) Water Gas shift Reaction: CO + H2O CO2 + H2 (H = - 41.2kJ/mol) (2) The water gas shift reaction is exothermic and needs as low a temperature as possible to proceed. Based on Le Chatelier's principle, the WGS reaction rate: (1) Increases with increase in steam fraction in the inlet gas (2) Decreases with increase in Hydrogen in the inlet gas (3) Decreases with increase in temperature The reactor temperature influences the flame temperature of the reactants. Hence at higher temperature more Methane is converted and less Hydrogen. The presence of a catalyst such as Nickel helps in the formation of Hydrogen rich reformate. The heat required for the first reaction is obtained by the combustion of fuel gas and/ or purge tail gas from the PSA system. Following the reforming step, the synthesis gas is fed into the CO conversion reactor to produce additional Hydrogen. This process occurs in two stages consisting of a High Temperature Shift ( HTS ) reactor at 350C and a Low Temperature Shift ( LTS ) at 190 to 210C.High temperature shift catalysts have an Iron Oxide-Chromium Oxide basis while LTS catalysts consist of Copper Oxide. 3.0 Gas Purification: Hydrogen purification by means of pressure swing adsorption (PSA). The PSA units reach hydrogen

History of Medical Education With Emphasis to Its Formal Origins Essay

History of Medical Education With Emphasis to Its Formal Origins - Essay Example This essay stresses that at the end of the century America still struggled to resolve the problems of its medical education. It is clear there was a realization that changes should be brought in order to remedy the situation in order to transform American medical education along the lines of European medical schools. However, real reform of American medical education did not start until Carnegie Foundation published famous report of Abraham Flexner Medical education in the United States and Canada This report entailed huge reforms in the quality of education that American medical schools provided. The fact that these reforms were not implemented in the USA at the end of 19th century can be explained by several reasons. First the USA was a comparatively young country and could not provide as much opportunities for the research as Western European countries could. Few doctors were among the first settlers of the USA (partly due to the limited possibilities for their practice in the continent), and the social status of those who settled in America was comparatively low. Most of the medical schools that were founded relied on the fees of their students, whereas in Western European countries Government took active part in financing of medical educational institutions. As the medical schools were struggling in the USA to find adequate finances they had to take into account the wishes and desires of the students, who wanted to receive their medical diplomas as quickly as possible, wh ich certainly in turn entailed the lowering of quality standards of medical education.

South Africa Apartheid History Essay Example | Topics and Well Written Essays - 1250 words - 1

South Africa Apartheid History - Essay Example Apartheid (1948-1994) cannot be considered as ‘the best solution’ for the country because it violated human rights and freedoms of black populations and caused separation between white minority and black majority. Primarily, apartheid was one of the main forms of racial discrimination, separation of white minority and black majority. Social divisions in this colonial society increasingly took on a rigid racial character1. Between 1950s – 1970s white power was used to forge one of the most extreme forms of racial discrimination in the twentieth-century world. For instance, whereas the strength and size of the settler population in the United States or Australia meant that race relations were for many years relegated to the peripheries of national historiography, race was an abiding concern even in the most inward-looking settler histories of South Africa2. Apartheid cannot be the best solution for South African because this term coincides with the concepts of racism, segregation and oppression of black population. Segregation in South Africa encompassed many different social relationships. It is often discussed as a series of legislative Acts which removed and restricted the rights of ‘non-whites’ in every possible sphere. Segregation was more than a set of restrictive legislation: it refers as well to a composite ideology and set of practices seeking to legitimize social difference and economic inequality in every aspect of life3. For instance, "Coloured" was the official apartheid designation for persons of mixed raceâ€Å"4. Many of the spatial and social elements of segregation, such as the division of churches on the basis of color, were initially governed by convention rather than law. It is important to mention the exclusion of blacks from skilled work, and especially from the exercise of supervisory functions ove r whites, was determined by custom as well as legislative

Mohammed ali clay - Research Paper Example As a professional athlete who popularized the sport and who remains one of the most well-known boxers of all time, Muhammad Ali was a three-time world heavyweight champion as well as an Olympic athlete. The following will explore the life and times of Cassius Clay/Muhammad Ali and discuss the important contributions that he has made to the boxing world as well as to the United States of America (About Muhammad 2009). Cassius Clay grew up in the 1940s Louisville, Kentucky, a community in which blacks and whites intermixed but there was also an undercurrent of racism which pervaded all aspects of society. Accordingly, racial segregation was a feature of the early boxers existence in Kentucky as the state practiced the infamous Jim Crow laws. Due to these restrictions on race mixing, education, healthcare, and a variety of other things such as rural road transport were segregated based upon race. Despite growing up in an era in which the color of his skin was a hindrance, Cassius Clay put whatever anger he had at the discriminatory and racist society in which he grew up towards boxing. As a young boy he began boxing and eventually won six Kentucky Golden gloves titles as well as an Amateur Athletic Union national title. Cassius Clay impressed boxing aficionados throughout the Midwest as well as nationally and he represented the United States in the 1960 Summer Olympics in Rome. Unknown to many, Cas sius Clay – later to become the world-famous Muhammad Ali - was an accomplished amateur boxer who won the light heavyweight gold medal for the United States in Rome in 1960. Racism was a serious problem in the United States during this time and the victorious Cassius Clay reportedly threw his gold medal into the river upon returning to United States and being refused service due to the existence of Jim Crow laws. Despite the fact that Cassius Clay successfully

The new age Essay Example | Topics and Well Written Essays - 750 words

The new age - Essay Example Like a number of ancient religions of the world, Scientology holds the view that people are placed on earth to establish their own salvation and they can only comprehend the relationship with God by realizing this. The appeal of scientology is in a person’s capacity to solve his own issues (Frost & Frost, 2012). When a person is able to solve his own problem, he is also capable of helping other individuals. It also allows a person to think for himself. Question 2 Both science and religion hold assertions to reality. Religion is made up of faith and belief. Religion claims events are factual because they want them to be, and they decline to alter their notions just because there are a number of infuriating information in the way. In contrast, science incorporates theory and evidence. Science asserts that things are factual because they concur with the proof and theory also gives it support. Additionally, if there is new evidence, the theory is modified, even if it requires givi ng up prior valued suggestions. In addition, every scientific theory is in principle refutable, and in the end every theory will be negated. In contrast, religion can in principle not be refuted. This does not play a part to its evidence. Moreover, religion cannot be proven (Frost & Frost, 2012). ... Moreover, globalization illustrates the connection between cultures of macro-social components. These components entail politics, economics, and religion. Also, globalization may universalize and wear down the features of a local grouping (Lewis, 2007). Significant factors in globalization include the advancement of the internet, telecommunications and transportation infrastructure. These factors generate additional interdependence of cultural and economic activities. Also, Atheism plays a part in globalization. Atheism refers to the refusal of belief in the being of divinity. It also implies that there is not a deity that exists. Atheists are less authoritarian, nationalistic, close-minded, prejudiced, ethnocentric, anti-Semitic, dogmatic, and racist (Frost & Frost, 2012). Therefore, they can sell their merchandise, goods, or services to all people and markets all over the world. Atheists are also pro-immigration and presume that any migration is beneficial migration because it is e ffortless to incorporate these individuals in the global culture. Question 4 Secularism refers to the rule of disconnection of government units, and the individuals authorized to represent the nation, from religious dignitaries and religious institutions. Secularism may highlight the claim to liberty from religious teachings and rule, and the liberty to freedom from governmental obligation of religion to the individuals in a state that is nonaligned on issues of belief. Secularism may also illustrate the notion that human beings decisions and activities, mostly political, must not be biased by religious authority. It is better that states embrace secularism than religion (Frost & Frost, 2012). This is because secular state will incorporate the views of the entire

Private Security Law Essay Example | Topics and Well Written Essays - 750 words

Private Security Law - Essay Example Private security agencies have played a vital role in preventing, detecting and investigating instances of crime on the employer’s premises (Dempsey, 2010). Private security agencies have engaged in activities such as cash transportation, building surveillance using closed circuit televisions (CCTVs) and alarm systems, and private investigation of crime (Dempsey, 2010). Private security law is contained in the Private Security Officer Employment Authorization Act of 2004, which licenses and provides guidelines for the operation of private security services and agencies (Dempsey, 2010). When it is necessary to search an individual on your employer’s premises, there are certain legal risks which the security persons should be concerned about. These legal risks present potential causes of action against the personnel. Laws protect individuals from being searched, since security personnel are not authorized to search individuals for the purpose of finding evidence to arrest them (Maxwell, 1992). To have an opportunity to conduct the search, security personnel should first detain the individual after discovering the ongoing crime (Maxwell, 1992). Security personnel should not assist in, or allow any opportunity of, disposing the items stolen from the premises. According to Penal Code 846, a member of security personnel is allowed to search for weapons only if he or she believes that he or she is in physical danger after detaining the suspect. The searching officer must be in uniform and a badge to avoid any misunderstanding between him and the suspect (Dempsey, 2010). Some potential risks that can lead to criminal liability during the search include intimidation of the suspect to make him or her cooperate and confess the crime (Maxwell, 1992). Another potential risk includes the use of excessive physical force which is unreasonable in restraining the suspects who resist the search (Pastor, 2007). Use of excessive and unreasonable force will lead to bot h criminal and civil liability of the private security personnel. For instance, discharging a firearm and shooting the suspect in order to ensure the safety of the employer’s property will lead to criminal liability, since deadly force is only permissible in protecting human life (Maxwell, 1992). The use of unauthorized deadly weapons such as switch-blade knives and guns will also lead to criminal liability. For instance, proprietary security guards are usually unarmed and thus cannot carry or use any weapons such as knives, batons and guns during the search, since they are deadly weapons. The unlawful use of defensive weapons like batons or making misdemeanor arrest will lead to criminal liability, since the security guard has not actually observed the suspect committing the crime (Maxwell, 1992). If the there is a reason to believe that a particular employee of your employer was engaging in anonymous harassment of a co-worker and you wanted to confront the individual in a m eeting in your office, there are several steps that you can undertake in order to reduce the legal exposure of the company by the alleged harasser arising from the meeting. The investigator should desist from spreading any rumors, gossip or false statements about the alleged harasser and should conduct fair and impartial investigations before the meeting in order to avoid causing personal harm to the alleged haras

The Future of Early Childhood Education Essay Example for Free

The Future of Early Childhood Education Essay If you ask someone to list for you the most important jobs of our society, teachers always make the list sometimes beating out careers like doctor or lawyer. Ironically, for a career we value so much, teaching has never been a well paying profession. But times are about to change. Due to an increasing demand and a fixed supply, salaries for early education teachers are expected to increase within the next decade. The United States Board of Labor ranks this career as one of the highest paying of the next ten years, with an expected median tenure salary of over ninety thousand by the year 2012. Even taking into account inflation, working conditions, and different peoples preferred lifestyle, it is reasonable to say that a career in early childhood education can provide a very comfortable living. The law of supply and demand helps us understand how price is set in our society. It states that if the supply of a good increases, or if the demand of a good decreases, then the price of the good drops. The opposite is also true, if the supply decreases and the demand increases, than a good becomes more expensive. The theory of supply and demand is very powerful, and can be applied to many different things. In this paper, it will be used to explain why teachers salaries are expected to increase a great deal. The number of teachers will be the supply, the need for teachers will be the demand, and salaries will be the price that will be affected. In 2002 there were over two million positions for early education teachers in the United States. Of the teachers in those jobs, about 1. 5 million were elementary school teachers, 424,000 were preschool teachers, and 168,000 were kindergarten teachers(Outlook). The majority of these teachers worked for the local government educational services, with about ten percent working for private schools. While the majority of preschool teachers are employed by child daycare services. Geographically, teaching positions vary with the population. Highly populated areas have more employment opportunities. Every year, a greater number of students enroll into the United States school system. More students increase the need for more schools and qualified teachers. In addition to the population growth, a number of initiatives have been implemented in a few states, but not nationwide, to improve the quality of education. The initiatives include the reduction of class size in the early elementary grades, mandatory preschool for four year olds, and all-day kindergarten. More teachers will be needed than are currently available if states and their local districts plan to enact any of these measures, preschool and early elementary school teachers are particularly in demand. Job openings for early childhood teachers within the next ten years are expected to be excellent. This is due in part to a government plan to great new teaching jobs. In the 1999 federal budget, Congress allocated funding to hire approximately 30,000 new teachers nationwide(section1). However the number of openings depends on locality, grade level, and subjects taught. These funds are targeted for needy school districts as part of a seven-year plan to hire 100,000 new teachers(section 1). These new openings will appear in poorer communities were salaries are currently lower, however because of the limited supply of teachers they will have to compete with wealthy distracts in order to attract teachers. Schools will be forced to raise salaries, bonuses, and benefits to attract teachers to these new jobs. These new jobs created by the government are not the only openings for teachers expected in the next ten years. Most job openings will be due to the expected retirement of a large number of teachers. Approximately half of the early childhood teachers in the workforce today are expected to retire within the next ten years. Studies estimate a demand of well over two million new teachers to fill these positions. Adding to the demand is the high turnover rate among new teachers and teachers working in poorer urban schools. Replacing all these teachers would be like trying to replace ever doctor in the United States today, but why will we need all these teachers? The children of the baby boomer generation are getting older, doesnt that mean that we are expecting a lower enrollment for earlier grades? No, in fact the opposite is true. Student enrollments will still be a key factor in the demand for teachers, in the next ten years. While the number or students expected to enter the school system is expected to rise at a slower rate than in the past, the expected number is still growing; resulting in average employment growth for all early childhood teachers. While the demand for teachers is increasing, the supply of teachers has been decreasing steadily since the 1970s. Historically, teachers have been paid significantly less than other professionals with their same level of education. Because of this, people have been more attracted to pursuing careers in business, medicine, or law, which have typically paid more. This resulted in few new entries into the teaching professionals, and an aging of the professionals currently working. As the demand for teachers increases in the next decade, more than half of those currently teaching will retire by 2012. While there is a great need for new teachers, there are barriers of entry into the profession that reduces the amount of people that are qualified to enter the field. All 50 States and the District of Columbia require public school teachers to be licensed. Licensure is not required for teachers in private schools. Usually licensure is granted by the State Board of Education or a licensure advisory committee. Teachers may be licensed to teach the early childhood grades (usually preschool through grade 3); the elementary grades (grades 1 through 6 or 8); the middle grades (grades 5 through 8); a secondary-education subject area (usually grades 7 through 12); or a special subject, such as reading or music (usually grades kindergarten through 12) (Outlook) The requirements for the regular license to teach kindergarten threw twelfth grade are different depending on the state. But no matter which state you apply, all prospective teachers are required to have a bachelors degree, a specified number of subject and education credits in an approved teacher-training program, and have to have supervised practice in teaching in a classroom environment. Different states have additional requirements, like having to complete a masters degree, having to have graduated with a certain grade point average, or special technological training. Most states require applicants to be tested for basic skills, like reading, writing, and in teaching. Almost all states require the teacher to exhibit proficiency in his or her subject. The number of teachers employed is not only dependent on how much the state and local government has set aside in its legislation to increase the quantity and quality in its districts. At the Federal level, the No Child Left Behind Act has recently been enacted. Although the full impact of this act is not yet known, its emphasis on ensuring that all schools hire and retain only qualified teachers, should lead to an increase in funding for schools that currently lack such teachers. The purpose of this legislation has been to increase the quality of the teachers in the workforce. To achieve this goal school systems are working to create a performance-based system for licensure. This would mean that not only would teachers have to have experience, but would have to show reasonable results for a defined period of time before they would be granted a provisional license. Due to No Child Left Behind Act, the test scores that their students attain will undoubtedly measure a teachers performance. All this would be in addition to passing a standardized exam in ones subject. Once a teacher is licensed, most states require continued education in order to have that license renewed. Licensing requirements for preschool teachers are also different in each state. Requirements for public preschool teachers are usually higher than those for private preschool teachers. Some states require a bachelors degree in early childhood education, others require an associates degree, and still others require certification by a nationally recognized authority. The Child Development Associate credential, the most common type of certification, requires a mix of classroom training and experience working with children, along with an independent assessment of an individuals competence. In 2002, the average annual salaries of kindergarten, elementary, and middle school teachers were reported to be forty to forty five thousand dollars a year or greater, with the lowest salaries recorded as twenty five thousand a year and the highest being seventy thousand a year. These salaries differ according to the location of the teacher. For example, teachers in wealthier suburban communities tend to earn more than teachers in urban schools. Also, while public schoolteachers tend to earn an average of forty five thousand dollars a year, private school teachers earn an average of fifteen thousand less. By the year 2012, the Board of Labor estimates the median salary of early childhood teachers to be approximately ninety thousand dollars, with the high salaries reaching as high as one hundred and ten thousand dollars a year. In addition to their salaried, teachers can increase their earnings in several ways. Most public schools, and some private, pay teachers bonuses for coaching sports or working with extra curricular activities. Some public schools pay teachers up to twenty dollars an hour for the overtime work, which can increase their annual income by an average of fifteen thousand dollars a year. Teachers can also raise their salary by getting a greater degree, like a national certification, masters, or PhD. Several teacher also choose to work threw their summer breaks for additional income, by teaching summer school or pervading other labor for the school district. While there is no estimates on how much teachers supplemental income is expected to increase by 2012, is it safe to assume that any benefits and bonuses will increase as well, in order to make teaching more attractive to qualified professionals. Standards of living are very subjective; it is possible that no two people would be able to decide what the standard is for a comfortable lifestyle. Our lifestyle depends on a great many things, our different taste, values, background and culture. However a survey of early education teachers in the New Jersey area shows that most teachers currently enjoy a lower middle class lifestyle. A majority of teachers feel that teaching affords them a comfortable lifestyle. Many live in suburban neighborhoods, own their own homes, own cars, are able to safe for the future, and have a little extra income for luxuries like fine dinning and vacations. Currently, teachers that enjoy this lifestyle are married and live in a multiple income household. However, most teachers that are entry level and rely on a single income find themselves living from paycheck to paycheck. While they feel they have enough to support themselves, they are not afforded the luxuries that their tenured, double income colleagues enjoy. However the future looks bright for early childhood teachers. The average salary for teachers is expected to more than double in the next ten years, from the current average of forty thousand to an expected average of ninety thousand by 2012. Salaries for some are expected to be as high as one hundred and ten thousand, depending on the region and subject taught. Salaries this high would allow teachers depending on only one income to enjoy the same luxuries that their married colleagues enjoy today, and teacher that life in multiple income households are expected to enjoy an upper middle class lifestyle. However, some people might notice that prices are higher today than they where ten years ago, and it seems that every year the average cost of living keeps increasing. This phenomenon is called inflation. Just because teachers will make more money in the future does not mean that that theyre standards of living will increase, because the cost of living will also be higher in the next ten years. To determine if there will be an increase in the standards of living for early high school teachers, we have to compare the increase in their salaries to the expected rate of inflation. Within the next ten years teachers salaries are expected to increase by over fifty percent, while leading economist in the United States Federal Reserve Bank expect inflation in the same period of time to be only eighteen percent. This means salaries are expected to increase more than the cost of living is expected to increase, which means teachers will have more purchasing power. Using these estimates, a salary of ninety thousand in 2012 has the same purchasing power as a seventy five thousand dollar a year salary does today. Even taking inflation into account the standards of living for teachers will increase within the next ten years, but there are more factors than just income than affect peoples lifestyles. Most people on the United States value their family and health as much, if not more, than how much money they make. In a survey of early childhood teachers in New Jersey, most teachers valued the ability to finish work at a reasonable hour and spend more time with their family when asked what they valued most about their careers. Having a two month vacation also allows for more leisure time and, and time to be spent with family. Many teachers also have excellent benefits, provided by either the government or teachers unions. In 2002, more than half of all elementary, middle, and secondary school teachers belonged to unions? mainly the American Federation of Teachers and the National Education Association? that bargain with school systems over wages, hours, and other terms and conditions of employment (Outlook). Unions also bargain for increased benefits, including medical, dental and vision benefits for teachers and their dependents. How much a person makes and the things they can afford are not the only factors that affect your life style. For some people money may not be important, they may not value compensation as highly as they value personal fulfillment from what they do for a living. Some people need the satisfaction that they are making a difference in the world, and have the desire to do something meaningful with their lives. For people with these values, seeing students develop new skills and gain an appreciation of knowledge and learning can be very rewarding. In this sense, a career in early childhood education also provides. Our society values the importance of teachers as much, if not more than the importance of doctors. Preschool, kindergarten, and elementary school teachers play a vital role in the development of children. What children learn and experience during their early years can shape their views of themselves and the world and can affect their later success or failure in school, work, and their personal lives. Preschool, kindergarten, and elementary school teachers introduce children to mathematics, language, science, and social studies. They use games, music, artwork, films, books, computers, and other tools to teach basic skills. Preschool children learn mainly through play and interactive activities. Preschool teachers capitalize on childrens play to further language and vocabulary development (using storytelling, rhyming games, and acting games), improve social skills (having the children work together to build a neighborhood in a sandbox), and introduce scientific and mathematical concepts (showing the children how to balance and count blocks when building a bridge or how to mix colors when painting). Thus, a less structured approach, including small-group lessons, one-on-one instruction, and learning through creative activities such as art, dance, and music, is adopted to teach preschool children. Play and hands-on teaching also are used in kindergarten classrooms, but there academics begin to take priority. Primarily kindergarten teachers teach letter recognition, phonics, numbers, and awareness of nature and science, introduced at the preschool level. Teachers design classroom presentations to meet students needs and abilities. They also work with students individually. Teachers plan, evaluate, and assign lessons; prepare, administer, and grade tests; listen to oral presentations; and maintain classroom discipline. They observe and evaluate a students performance and potential and increasingly are asked to use new assessment methods. Including school duties performed outside the classroom, many teachers work more than forty hours a week. Part-time schedules are more common among preschool and kindergarten teachers. Although some school districts have gone to all-day kindergartens, most kindergarten teachers still teach two kindergarten classes a day. Most teachers work the traditional ten-month school year with a two-month vacation during the summer One of todays biggest political issues has been that of Social Security, and the fear that there will not be enough money to cover all the people that are currently in the workforce. It is scary, but people that are thirties years old now might not be able to retire under social security, even though they have been paying into it for the past ten years. However, this is a problem that most new teachers will not have to live in fear of. In his 2005 State of the Union Address, President George W. Bush made a promise that all municipal workers will be guaranteed a pension when they retire. Weeks later a Federal Commission started planned a new defined contribution pension plan. The new plan resembles what is commonly called a defined benefit plan, which was a popular pension plan for large corporations up until the 1990s when 401k retirement plans became popular. The appeal of the defined benefit plan is that it guarantees you a fixed monthly income for the years you are expected to live after retirement. The amount of that monthly income is based on the salary you have when youre working, and is designed to maintain your same standards of living that you enjoyed while working. Unlike the 401k, the employer funds a defined benefit plan. Most States have tenure laws that prevent teachers from being fired without just cause and due process. Teachers may obtain tenure after they have satisfactorily completed a probationary period of teaching, normally three years. Tenure does not absolutely guarantee a job, but it does provide some security. In conclusion, increasing enrollment in the school system is increasing demand for new teachers. New legislation to increase the quality of education, barriers of entry, as well as a large number of teachers reaching the age of retirement is reducing the supply of qualified teachers. As a result, according to the theory of supply and demand, the price that society must pay for qualified teachers must increase. Salaries for teachers must increase in order to attract enough teachers to fill the demand that society has for them. The greater the gap between supply and demand, the greater the price must increase in order to fill the gap. As salaries increase, so will the standards of living for teachers. A teachers salary will not only provide a person with the means to make a living, but they will also have expendable income for savings and luxuries that will lead to a more comfortable life style. Most teachers will also have benefits that will provide for their well being and health, as well as the health of their families. They will have more time off than other professionals, which will provide them the luxury of pursuing other interests outside of their career. This includes taking vacation, exploring other career opportunities, or just spending time with their families. State employed teachers will not have to worry about retirement, because they are guaranteed a pension salary once they retire. Teachers will not have to stress or fear for the future like some other members of the workforce who were relying on social security. Early childhood teachers also have the satisfaction of having a career in one of the most respected professions in our society. They will have to fulfillment of knowing that what they do makes a difference. Works Cited Case, Karl E. Principles of Macroeconomics Sixth Edition. Prentice Hall Van Dalen, Deobold B.

Foam Assisted Lift Technology to Improve Recovery Factor

Foam Assisted Lift Technology to Improve Recovery Factor PROCEEDINGS, INDONESIAN PETROLEUM ASSOCIATION Forty first Annual Convention Exhibition, May 2017 Foam Assisted Lift Technology to Improve Recovery Factor from Sensitive Wells, lesson learned from Total EP Indonesie Ramot Sianturi* Jodi Astorifa Anggoro* Muhammad Nadrul Jamal* Chiko Eko Jatmiko* ABSTRACT Total EP Indonesie (TEPI) currently produce ÂÂ ±1600 MMSCFD of gas from 5 major gas fields, which are Tunu, Sisi-Nubi, South Mahakam, Peciko and Tambora. Except South Mahakam and Sisi-Nubi, all other fields are mature and already in declining production. On some very sensitive gas wells, there have been liquid loading problem observed, a phenomena of inability to continuously lift liquid from borehole. The accumulated liquid increases hydrostatic pressure and eventually stop the well production. As a solution, TEPI introduced a Foam Assisted Lift (FAL) technology in 2011 as a pilot phase, and continued in 2012-2013 on more wells part of FAL trials. The principle of FAL is to generate bubbles to reduce hydrostatic pressure, through surfactant injection from surface to down-hole using capillary string (CS) set under specific well intervention arrangement. Starting from the pilot phase, TEPI have performed several improvements and development of robust down-hole equipments, operation, and also the selection criteria of candidate wells. During several phases of FAL pilots, TEPI had defined the selection method and criteria of good FAL candidates; good productivity (defined as Porosity x Net pay thickness), good offload response, condensate and liquid ratio less than 60%, and bottom hole shut in pressure higher than 1000 psi. The new selection criteria was fully implemented in 2015 campaign, and resulted in improved production in 10 wells. FAL is considered as proven technology to maintain production stability of very sensitive gas wells. Keywords: Capillary string, liquid loading, foam assisted lift, selection criteria INTRODUCTION Total EP Indonesia (TEPI) produces ÂÂ ±1600 MMscfd in 2016, it was decreasing sharply from 2010 which could produced ÂÂ ±2000 MMscfd. One of the main challenges to maintain the plateau production of TEPI is the liquid loading issue which means the inability to lift liquid out from gas wells. This liquid loading issue triggers to self killing process as shown in Figure 1. In the beginning of wells life, well produced in high gas rate and relatively dry. Through the time gas production decreases, water starts to be produced and less energy to lift the liquid. As the consequence, liquid will start to be accumulated in the borehole then eventually stop the well production. Liquid loading issue would always happened in gas wells, it just only the matter of time. To minimize and longer wells life, until recently TEPI performs regular offload by decreasing Well Head Flowing Pressure (WHFP) close to atmospheric pressure and flaring, involving substantial means such as testing barge and personnel. These offloading activities present specific risks, not only for safety, personnel, and assets, but also impact in environment from the flaring activity which results in Green House Gas (GHG) emissions. Moreover, this offloading is only temporary solution to boost the production. Therefore, a continuous offloading system is required to maintain the sustainability of production. Several technologies for continuous offloading are shown in Table 1. Based on Table 1, the most possible technology to be applied is Foam Assisted Lift (FAL) through CS considering no energy required, comply with company rules, and less cost compare to others. Principal of FAL is by creating foam at down-hole to reduce the hydrostatic pressure at wellbore in order to help the lifting of liquid to surface. The process sequence of FAL is shown in Figure 2; Addition of surfactant inside the well will reduce gas-liquid surface tension The reduction of surface tension will impact to the reduction of liquid density Hydrostatic pressure will be reduce as the impact of lighter liquids density Reduction of hydrostatic pressure will give more drawdown, delta pressure between reservoir pressure and bottom hole flowing pressure (BHFP) Additional drawdown will give more gas rate production Technology FAL has been developed in TEPI in 2011 as a pilot phase and continued in 2012-2013 on more wells as part of FAL trials. Starting from the pilot phase, TEPI have performed several improvements and development of robust down-hole equipments, operations, and also the criteria of candidate selection. CAPILLARY STRING INJECTION SYSTEM Down-hole Equipment CS down-hole system is an additional tubing (injection system) that inserted inside production tubing. Even though additional CS inserted inside, TEPI still complies and respects to safety by keeping down-hole safety valve (DHSV) installed. It is mandatory to equip subsurface safety valve in onshore and offshore wells in TEPI for safety purpose as second barrier if any damage or malfunction of surface system happened. Initially the DHSV opening and closing is controlled by hydraulic pressure from control panel but after equipped with CS down-hole system, the opening and closing is controlled by surfactant pressure from surface surfactant facilities. DHSV in CS well is inserted or incorporated in a Weatherford Injection and Safety Hanger (WISH). The WISH hanger also locks the CS tubing, top and injection valve, and dual check valves as shown in the Figure 3. Dual check valves are used at top and bottom injection valve to prevent well pressure from production tubing entering the system in CS tubing and DHSV control line. Besides that, the purpose of dual check valves also to prevent reverse flow of surfactant or fluid s from wells which is potentially could cause plugging. Top injection valve installed immediately after WISH with purpose to pressurize and open DHSV at certain cracking pressure (ÂÂ ±2000 psi) then it will allow surfactant to flow to bottom part of CS tubing. Bottom injection valve is installed at the bottom part of the tubing with purpose to inject surfactant inside production tubing. Surface Facilities Surface facilities were designed to allow the surfactant injection from surface to wellbore with consideration to safety aspect, production reliability, and production availability. Whole surface facilities in CS well are shown in the Figure 4. CS surface facilities consist of several equipments as follow: Surfactant tank; Tank that used shall be made from metallic tank since based on MSDS, surfactant is consider as flammable fluid. Pump; Surfactant injection pumps type is positive displacement driven by instrument gas. In the earlier phase, installed pump is only one but due to the frequency of pumps failure, it is decided to install dual pump with philosophy one in operation and one as back-up. Pressure Switch High-High (PSHH); PSHH is installed to protect the equipment from overpressure due to blocked outlet discharge of surfactant injection line or reverse flow from reservoir. Pressure Switch Low-Low (PSLL); PSLL is installed to identify any leak/ rupture in the injection line or to identify if the pump stop working that could lead to pump cavitations. Pressure Safety Valve (PSV); PSV is installed at discharge line of pump to protect the surface facilities Surfactant Criteria that shall be considered during surfactant selection process are the foam efficiency and stability. Several laboratory tests have been performed to check and validate these two criteria. Qualifications of surfactant that been used in TEPI are as follow: The product could be used high temperature environmental ( ÂÂ ±1760C) since it would be injected up to wellbore No plugging issue cause by surfactant if injection stopped Compatible with other chemicals that injected in the flow-line, i.e corrosion inhibitor CANDIDATE SELECTION In the early phase on 2011, candidate of CS wells were selected based on the wells behavior (stable or intermittent flow), offload frequency, turner rate, and response to shut in for pressure build up (SIBU). The preliminary step for candidate selection is the wells behavior review before going in to deeper to the other criteria. A well that suffered with liquid loading could be identified by increasing of water production rate, and then followed by sudden decrease of gas production rate and decreasing of liquid lifted to surface that corresponding to the critical/ turner rate reached. The trend of WHFT also gives a good sign to do preliminary selection. Case 1 Well with Low Productivity and Low Gas Rate during offload Figure 5 is one of CS wells production evolution profile that selected based on the selection criteria above. As shown in the graph, the well still gave response to the offload that performed on October 2012 with high water production, ÂÂ ±700 bwpd but in limited gas rate, ÂÂ ±0.5 MMSCFD. This well clearly shown outflow problem as describes on liquid level column inside well based on pressure and temperature survey that given on Figure 6. CS was installed on May 2013, but there was no significant improvement in gas production even it was clearly confirmed that the well has issue in liquid lifting. Existence of water and response to offload could not ensure the successful of FAL, cut off of gas rate required to ensure the agitation and mixing between liquid and gas needs to be defined as well. Besides that, the productivity of the well needs to be checked as well. As shown in the IPR and VLP curve, well with higher productivity will give higher gain in any changes on VLP shape. Case 2 Well with Higher Condensate Liquid Ratio Figure 7 is sample of CS well that have high condensate ratio in liquid, ÂÂ ±80% of condensate in liquid. Based on the graph, gas rate production since October 2012 shown decreasing trend but still responsive to SIBU and offload (Qgas rate offload on August 2013 gave value ÂÂ ±1.5 MMSCFD). Considering the initial selection criteria, this well was a good candidate for CS, but after installed with CS, there was no significant improvement. Unsuccessful result potentially caused by the existence of high condensate rate. Since surfactant that used as FAL is water base, it would create foam if only water exist in the certain composition. If liquid consist more condensate, foam will not be created and the impact potentially will give additional back pressure to the well itself. Case 3 Well with Low Bottom Hole Shut In Pressure (BHSIP) Well in Figure 8 was installed with CS since August 2013. As shown in the graph, even though the well shown positive response in offload (Qgas rate at ÂÂ ±3 MMSCFD) and mainly produced water instead of condensate, the result after CS installation did not show positive improvement. Reviewing further from reservoir point of view, this well indicated a good productivity but the pressure (BHSIP) has been at low value. Based on the result on CS wells that selected based on criteria above (conventional approach), found that criteria above were still not capable enough to give higher success ratio. As in cases above, several parameters should be included in the selection process, such as productivity, response to offload, condensate liquid ratio, and BHSIP. Statistical approach has been performed to define the new selection that could give higher success ratio. Based on the review, parameters or criteria that could improve the success ratio are as follow: Productivity As shown in the Figure 5, more gain could be reached in the high productivity wells. The unloading of well with FAL through CS would give additional drawdown in front of the reservoirs. In the same drawdown, the higher gain would be given by the well with higher productivity. In TEPI, the productivity is represented by the height multiply with the porosity. The higher the height and porosity, the higher would be the productivity. In order to improve the success ratio of CS wells, TEPI implemented the cut-off productivity at value 250. Response to Offload FAL by surfactant does not bring any additional energy to the system. The well itself should be able to revive by itself in order to activate the foaming effect efficiently and effectively. Therefore, response to the offload is important to confirm CS candidate prior the installation. Good candidate for CS shall have an improvement in gas rate and liquid production at atmospheric pressure compared to LP. Based on review in existing CS wells, cut-off value to confirm candidate CS that implemented in TEPI is 1.3 MMSCFD in offload condition. Condensate liquid ratio Condensate is natural killer of foam. It would collapse the existence of foam. Based on laboratory test, minimum of 40% water in the liquid is still sufficient to create effective and stable foam. Therefore, the ratio of condensate and water needs to be considered as well during the selection candidate process. BHSIP BHSIP value could be used to represent reservoir pressure. Therefore, candidate for CS wells shall still have high BHSIP, it would not be too depleted reservoirs. Even though BHISP is used as one of the criteria, needs to be careful in the selection process since higher BHSIP could be also due to higher liquid column. Case 4 Well that Selected Based on New Selection Criteria New selection criteria that are included the cut-off productivity, gas rate during offload, condensate liquid ratio, and BHSIP have been fully implemented in 2015. TN-H13 is one of CS well that already selected based on this selection criteria. Productivity that represents by the value of height multiply with porosity is ÂÂ ±460 meanwhile the cut-off is at 250 Last offload that performed on August 2013 still gave value at 2.6 MMSCFD meanwhile the cut-off is at 1.3 MMSCFD Condensate ratio was at ÂÂ ±34% before CS installed meanwhile the cut-off is at 60% BHSIP based on pressure and temperature monitoring is at 1600 psi meanwhile the cut-off is at 1000 psi As shown in Figure 9, Production trend from point A (February 2014) to point B (May 2014) shown decreasing trend and limited water lifted to surface. In the end of May 2014, after reviewed based on new selection criteria, well gave significant improvement in gas rate after installed with CS. Gas production from point B (ÂÂ ±0.7 MMSCFD) increase to point C (ÂÂ ±2.5 MMSCFD) and then gave stable production. Good response to the FAL technology also given by the increasing of water rate that could lifted to surface. These new selection criteria have been fully implemented in 15 wells along 2015 and gave production improvement in 10 wells. DOWNHOLE MEMORY GAUGE As part of learning process, beside define the new selection criteria, the impact of surfactant injection rate on reduction of BHFP needs to be evaluated as well. The method to evaluate this BHFP reduction is by installing memory gauge at the edge of CS tubing. Total memory gauges installed are 5. TN-H13 is selected based on the new selection criteria and it gave positive result in gas production after installed with CS. Positive impact on the gas production could be explained in Figure 10. Performed test was by varying the injection rate through several periods. It was started with low injection rate to maximum injection rate. Stabilization period was given each time injection rate changed. The purpose of stabilization period is to have same baseline in each step of injection rate. Increasing of injection rate gave inline result with increasing pressure reduction of BHFP. At the end of the trial, surfactant injection was stopped in order to see the impact in pressure reduction of BHFP. From Figure 10, it is clearly shown that by stopping surfactant injection, BHFP would be back to initial value. Therefore, it could be concluded that the addition of surfactant obviously gives positive response to production improvement. The addition of CS gave reduction of BHFP by 160 275 psi, which means additional drawdown is given to the well that will impact to additional gas rate. CONCLUSIONS Fully implementation of new selection criteria (productivity, response to offload, condensate liquid ratio, and BHSIP) are applied in 2015 campaign. It is confirmed that the implementation could improved production in more than 10 wells. Surfactant injection inside the well that suffered with liquid is confirmed could give additional drawdown that impact to the addition of gas rate production as confirmed from memory gauge installation result. FAL is considered as proven technology to maintain production stability of very sensitive gas wells.
