Section 1 Presentation Foundation  â â  Ethics is a way of thinking of life and turned into a piece of the business world. The multifaceted nature and basic needs of the social insurance industry are progressively inclined to clinical mistakes which could cost human lives. The nature of care is estimated by moral elements related with the clinical business. Be that as it may, morals go past nature of mind and remember numerous different zones for the medicinal services industry. The job of social insurance organization in the association is to guarantee that clients are secured totally and that their protection are not damaged.  â â â  The practice of morals is likewise one of the obligations and duties of the Health Care Administrator and all things considered, the current paper plans to recognize the position and practice of morals in the medicinal services industry with other non social insurance businesses. In doing as such, the paper plans to pick up experiences of moral acts of non-medicinal services businesses and attempts to suggest the prescribed procedures for the social insurance industry if holes are found. So as to assess the key issues of moral practices in the two segments, the paper considers the Information Security part of business Information.  â â  Thus, the paper intends to think about the moral practices essentially gathering in the essential zones of data Privacy and Security from social insurance and the E-trade segments. Each capable movement in any composed area of human undertaking requires some type of guideline. Regardless of whether it is composed or unwritten, legitimately recorded or ethically reported, the examination likewise attempts to watch the moral practices against the business explicit moral gauges and lawful arrangements.  â â â Ethics can be characterized as realizing of what is correct or off-base and afterward making the best choice. By and large, morals are focused on the representatives of associations whose administration experienced issues. LAW AND ETHICS  â â â The Legal Information Institute (1999) characterizes â€Å"law† as a lot of decides that are viewed as general and that show both inward and outside consistency. They are advertised and are normally acknowledged by the general public in which they are distributed. They ought to likewise be authorized. Such laws are guidelines that oversee how people in a given society are relied upon to act toward others, who make up the general public, and principles the people who live inside that condition are required (and not simply expected) to stick to. The legislature is liable for authorizing such laws, and is enabled to utilize security powers to guarantee these laws are upheld. Sue Anstead (1999) has distinguished five after standards that must exist for laws to be considered accordingly: consistency, all inclusiveness, distribution, acknowledgment, and authorization. In the first place, Consistency alludes to the possibility that opposing prerequisites can't be viewed as law, as it would be incomprehensible for individuals to comply with both. Second, comprehensiveness exhibits that the necessities ought to apply to all who share comparable circumstances inside a given society. Third, distribution advances that the necessities ought to be accessible to all by means of some strategy for composed distribution. Fourth, acknowledgment implies that the necessities must be commonly viewed as fitting. At the point when acknowledgment of the law happens, it will be almost generally complied. At long last, the authorization rule mirrors that the individuals from the given gathering must be compelled to conform to the guideline and rebuffed should they decide to rebel.  â â â â Anstead (1999) has likewise noticed that the Greek word ethos is that from which the English word â€Å"ethics† is determined. The Greek word is one that implies character, and what might be compared to same words adds the possibility of custom to the importance of the term. The mix of these thoughts mirrors the decision that individuals inside a general public make with respect to their method of association. The philosophical rendering of the word â€Å"ethics† gives the definition as that which is acceptable or healthy for the individual just as his social condition and it additionally depicts the obligations that ought to be performed starting with one individual then onto the next.  â â â â Ethics has numerous philosophical characteristics that one may depict as â€Å"common† to all types of the term. It is worried about the worry of things considered acceptableâ€or the recognizing of right from wrong. Besides, morals are planned urge the people to pick the directly over an inappropriate. Choices that are viewed as moral are commonly gone to by outcomes that reach out over a perceivable period. There are likewise commonly a few alternatives in regards to conduct, with the goal that an individual must settle on a decision to be moral in his/her conduct.     However, morals are not viewed as equivalent to ethical quality. The distinction that lies between them is fragile yet critical to learnâ and comprehend. Judgment is at the core of profound quality, as it has to do with certain â€Å"standards of conduct by which people are judged, and [†¦] which individuals by and large are decided in their associations with others (Anstead, 1999).† Ethics, in any case, varies from this as it encloses the whole conviction framework whereupon a specific adaptation of profound quality rests. The qualities associated with morals and those standards one finds related to the law are commonly identified with one another. Be that as it may, moral obligations are regularly more prominent than legitimate ones. Notwithstanding, the inverse is likewise evident now and again. In actuality, it may be said that â€Å"although law most occasions exemplifies moral standards, law and morals are a long way from co-broad (Ibid).†  One finds that no laws exist against specific activities that might be considered even by numerous individuals as untrustworthy. Then again, the law prohibits a few demonstrations that are not viewed as dishonest however may simply be perilous. Instances of these flourish, yet just to name a couple: making bogus cases about a specific circumstance or deceiving the trust of a companion is, by and large, not thought about unlawful. In any case, such a demonstration is generally viewed as deceptive. Likewise, speeding is illegal, however many would concur that a great many people don't discover such an activity untrustworthy (AMA, 1994; Anstead, 1999).  â â â McNamara (1999) has portrayed a situation in which the connection among law and morals is delineated. When setting up a lot of models or rules that help in the identification, goals, and the warding off or debilitation of penetrates to moral codes, an association is regularly made sure about against inclusion in further lawful issues. As per Anstead (1999), â€Å"Federal condemning rules went in 1991, for instance, grant judges to decrease fines and prison time for administrators proportionate to the moral estimates an organization has taken (Ibid).† This settles on it a savvy choice for any organization to set aside effort to build up a code of morals. On the off chance that an association creates positive techniques for managing circumstances concerning morals, this will offer them the chance to broaden alleviated disciplines, if lawful infringement do happen.  â â â Guidelines or codes that administer the direct of people, and which are of the sort that is generally settled upon as great activities, ought to be given to the general population in composed structure inside a report.

Supplier Selection for the Contract of GH’S Hazardous Waste Disposal

As demonstrated in UoL, (2013) Assignment study case General Hospital (GH) conjectures delivering an expected normal of a day by day squander equivalent to 5 Kg for each day and the GH works 52 weeks/year, 7 days/week so the evaluated squander every year 5*356 = 1780 Kg for each Year.Due to poor guaging process 7 information of GH according to their recorded information, the estimated exactness is 80% every year, therefor providers must consider in his computations the danger of having 20% expansion in the squanders amounts 1780*20%= 365 Kg/Year = 1 Kg/Day because of that providers must incorporate a costs List for Extra administrations in their offers. Three providers reacted to offer to GH delicate greeting and gave the best offers they have according to underneath schedule:Quality.In our examination case the referenced exercises are straightforward and not muddled, so dependent on the above advances that I will use to pick the best provider and offer. What's more, according to the above timetable GH obtainment branch of (GH) investigation and assessment of two components cost and administration, the examination results for the fundamental three providers A have the best assistance, provider B have the best cost, and the provider C is out of the opposition since his offer isn't clear about the cost and constrained conveyance ability.Analysis of the Price:A and B providers gave a nitty gritty cost for their activity charge and their waste amounts get limit the essential assessment result mirrors that the provider B has the most minimal cost = 1,157 and the provider A cost =1673. 2 an alternate of 516. 20 â‚ ¬ between the two costs, provider C couldn't have a last cost for indistinct data. Administration investigation: according to the determined gauge of the waste created day by day by the GH is around 5 kg for every day, providers An and B gave a proposition of container’s limit 100 kg for An and 50 kg for B.â suppliers An and B likewise gave an On -Call choice for the get, substitution, and removal activity. (UoL, 2013)Suppliers need to comprehend the necessity of GH and the measure of hazard for keeping the loss inside the holder and what is the reasonable length to keep the loss without removal. An and B providers have given a serious offers, provider A demonstrates the preparation to arrange with respect to his proposal so as to reach to the best settlement. (UoL, 2013) Negotiation Process: GH will direct an exchange meeting with the Supplier A.According to Sollish et al. (2011, pp. 136-140) it is critical to characterize the components that you will haggle about it before directing the exchange and set up appropriate and communitarian condition for the customer and the provider. A portion of the fundamental components that the GH acquirement office need to talk about as follows The limit of the holder: According to the day by day estimation of the waste 100 Kg is excessively and GH need to assembles provider A to decrease the expense of the get activity charge by using less limit containers.Safety and Environment systems should be examined and how and what is the most ideal approach to gather such sort of waste with ideal quality execution without imperiling the soundness of the individuals and the earth. Win-win is one of the fundamental highlights of synergistic exchange. The principle target is to dissuade provider An and diminish the all out expense of his offer. All the exchange exercises and results should be reported on the off chance that required in the future.In the end if the arrangement didn't worked out in a good way for provider A one of the exchange strategies that should be prepared even before beginning the arrangement what called Best Alternative to a Negotiated Agreement (BATANA) McGraw-Hill (2006, p. 21 expressed that â€Å"Alternatives are likewise significant on the grounds that they enable moderators to leave any exchange when the developing arrangement isn't very good† and furthermore it is smarter to have your BATNA prepared to contrast it with the accessible proposition with â€Å"see whether it better fulfills your interests† . (Fisher et al. 1999, p. 51)My best option is to give the agreement to provider B which has much better cost and less limit compartments which will include an incentive in the calculated activity and gives less time to save the loss around the emergency clinic for ecological issues, with the evaluated 5 KG squander every day the holder will be moved each 10 to 11 days.

Informal Carers Work In Partnership Health And Social Care Essay

Casual Carers Work In Partnership Health And Social Care Essay As expressed in square three Formal carers are contracted paid carers this could be as contracted network medical attendants or emergency clinic nursing staff or care home staff just as other paid contracted carers/staff. Casual carers could be unpaid relatives or companions potentially network put together carers or for the most part somebody with respect to an intentional premise thinking about a companion relative or in a workplace. We are likewise noting I'm not catching health's meaning? How might carers guarantee wellbeing? Is it just preparing a solid dinner or offering enthusiastic help for a relative or increasingly complex issues like taking care of an evil patient nursing them back to full wellbeing? Suggestions for wellbeing I feel would have a positive result when the two organizations cooperate it would guarantee better correspondence and understanding and furthermore have better contribution for the two gatherings. Proof for this is could be child care; working with social administrations and encourage carers getting a youngster into a caring long haul cultivate home consequently guaranteeing the childs mental and physical wellbeing is acceptable and their requirements be it enthusiastic or physical are met. We can likewise say this could be when medical clinic staff and familys cooperate to get a relative out of emergency clinic and well. Permitting families in medical clinic to help with the physical needs of the patient ie: washing and dressing enabling the family as they would feel significantly more feel associated with the recuperation and possibly this would help in accelerating the recuperation of the patient, this would likewise remove some weight of as of now exhaus ted nursing staff. Administrations, for example, city social insurance association (NHS Hull) help limit the requirement for intense consideration in emergency clinic through early mediations, network based treatment and advancement of sound ways of life this is an association that works with various wellbeing administrations and organizations to offer help and care accordingly helping patients, families, administration clients and care suppliers with better wellbeing offices and bolster which thus will makes a more grounded system of care this is the place casual and formal consideration is interlinked. Social specialists have an influence in guaranteeing organizations cooperate, be it familys or wellbeing experts this additionally guarantees better strength of the administration client and strengthening to families and carers the same. Care administrations have improved throughout the years and furthermore information and duties, accordingly giving better access to mind and backing to customers and their families A two-year study, dispatched by the Department of Health, saw 16 destinations across England which framed an Integrated Care Pilot program. The destinations trialed various methods of incorporating care, for example, between gps, network medical attendants, clinics and social administrations. Research did by Ernst Young, RAND Europe and the University of Cambridge (2012) considered the effect of better incorporated consideration on older individuals in danger of crisis clinic affirmations and the treatment of conditions including dementia and psychological wellness issues. It took a gander at staff and patient perspectives on crafted by the pilots conspire and furthermore the effect on emergency clinic confirmations and lengths of remain in medical clinic. This report found that enhancements for care expanded and cost to the NHS diminished when incorporated organization plans were set up. In an ongoing audit, Ovretveit (2011) reasoned that the response to the inquiry Does clinical coordination improve quality and set aside cash? was Yes, it can; contingent upon the methodology utilized and how well it was completed. In spite of vulnerability and strife uncovered in the report the requirement for incorporated consideration keeps up a generally excellent way to deal with guaranteeing sufficient human services and administrations, and much exertion has been placed into gaining from different nations that as of now embrace this methodology (Rosen et al., 2011) iv and giving direction to the NHS on methodologies that could be utilized (Ham et al., 2008v; Lewis et al., 2010vi; Ham and Curry, 2011vii). Casual consideration despite everything remains the transcendent sort of care gave as appeared in the 2005() division of human services report into the job of casual carers, it demonstrated that of which the jobs and duties gave by social administrations and chambers 1.47 million customers (85% all things considered) got network based administrations following evaluation, and 250,000 customers got private based administrations following appraisal. I think in general the suggestions for unexpected frailty would be moderately little when formal and casual carers cooperate. In the event that a decent degree of shared obligation isn't met this could mess up the administration client or potentially the families or care/nursing staff. Things like families and care staff not conceding to the degree of care required or thoughts of care along these lines causing the customer/patient to be conflicted between formal and casual consideration rehearses this might imperil the soundness of the customer. Additionally poor correspondence would affect the strength of the customer which could bring about conceivable disregard or potentially a decrease in their psychological state. 852 words References http://www.chcphull.nhs.uk/pages/about-us4 http://www.healthknowledge.org.uk/general wellbeing course book/clinical human science arrangement financial matters/4b-medicinal services/section9 Ham C, Curry N.

TMA04 Part 2 Evaluate the commitment that screening projects can make to the populaces wellbeing. I figure we first need to set up what is screening and what kinds of screening programs are accessible. Screening is a procedure of distinguishing obviously solid individuals who might be at expanded danger of a sickness or condition. They would then be able to be offered data, further tests and suitable treatment to decrease their hazard or potentially any inconveniences emerging from the malady or condition. Treatment would then be able to be begun expeditiously guaranteeing personal satisfaction and empowering counsel on issues, for example, way of life decisions. This precaution measure can improve endurance as we see from early recognition of bosom malignant growth (Tabar et al., 1989) There are many screening programs accessible extremely numerous to make reference to a long ways from 10-15 years back. There is no precise proof that states exactly what number of screening programs are running at present yet as indicated by the uk screening entrance there are more than 20 fundamental screening tests accessible testing aortic aneurysm where an expected 5000 individuals bite the dust every year to sickle cell malady where 17,354 recognized as bearers and numerous a lot more in the middle. Many expect to analyze conceivable sickness far prior and even before any patient has side effects; some screening programs are focused on new conceived babies and even infants still in the belly down condition screening program is nevertheless one of these in utero programs this is a consolidated blood test and exceptional kind of ultrasound test known as a nuchal translucency filter and in spite of the fact that it is beyond the realm of imagination to expect to forestall this hereditary variation from the norm that causes Downs disorder, it has gotten conceivable to distinguish all the more precisely during pregnancy the reasonable hazard that the infant is influenced and counsel and choices on what to do next would then be able to be looked for. As expressed in unit 14 infection can't be completely lighted yet it very well may be decreased by deterrent activity and early identification through screening is a decent method of doing this. Screening programs appear to convey a positive result, sparing numerous lives through early identification despite the fact that similarly as with most issues in the wellbeing administration cash has an influence and it has been bantered on whether it is essentially too expensive to even think about using all these screening programs than to simply regard sicknesses as they show up (Butler., 1993) There has been a lot of discussion on screening being a misuse of cash as announced by the bbc in 2009. The chlamydia screening program as it was accounted for by The National Audit Office that  £17m could have been spared, about a large portion of the total spent, if the program had been exceptional run as failings in this program prompted numerous under 25s not being tried , the ideal objective gathering. There is heaps of proof through the NHS site to propose that screening does spare and improve lives however there has additionally been recommendation that an individual could be pointlessly stressed or even hurt on the off chance that they are tried for something the NHS just can't treat this would without a doubt cause incredible pressure and anguish. As expressed in unit 14 research has concentrated on numerous potential dangers to screening programs a report by Marshal (2006) Stated numerous physical and mental mischief can happen because of screening programs as an individual stepping through the examination could be wrongly marked as debilitated or at high hazard this could prompt the individual utilizing this as motivation to surrender or let themselves go. In spite of the fact that screening programs are intentional so any worry would be talked about with a specialist preceding having the screening test done and screening would be finished in view of the interests of the pati ent and as a need. I think this hazard factor must be evaluated on an individual premise on whether it is ideal to know or simply receive a cautious methodology. Numerous individuals with sickness which is genetic would I think need to know whether they would too be hit with a similar disease despite the fact that I have met individuals in my line of wellbeing work which essentially would prefer not to know. Information is certainly force and I feel that screening projects must be something to be thankful for forestalling and assisting with forestalling and destroy numerous illnesss and sicknesses this

Creating Dynamic Characters Your Readers Will Love

Creating Dynamic Characters Your Readers Will Love You hear a lot about dynamic characters and the reasons for creating them. For a book to become a bestseller, dynamic characters are a necessity. But what is a dynamic character and how does an author pull that multi-dimensional character from his or her mind and on to a three-dimensional page?The official definition of a dynamic character is one who undergoes changes throughout the narrative, due to conflicts he encounters on his journey. The unofficial definition is a character who, throughout the story, is starkly and wonderfully human. Lets explore that for a minute or two and determine what traits take a character from static and flat, to dynamic and rounded.Creating a dynamic character involves the changes that take place throughout the narrative. Photo by Ollyy on Shutterstock.Real people change, but they do it slowlyYouve likely heard the adage that people dont change, and perhaps in some ways, this holds true. However, its not really telling the full storyâ€"which is, people can and do change, its just extremely difficult for that change to occur. And this is the reason a dynamic character (who changes over the course of the narrative) is so difficult to create.The character arc a dynamic character must demonstrate is one that takes him or her from the familiar or ordinary, into something extraordinary, and its this adventure that brings about a change. As demonstrated in the heros journey, the hero must leave the ordinary world, have moments of self-doubt, meet a mentor or teacher, gain allies and enemies, and enter into the dark night of the soul to go through these kinds of changes. It isnt something that happens overnight and it isnt something that occurs without exceptional effort.Real people make mistakes and are far from perfectIf you go about creating a character who is absolutely perfect in every way, your readers simply wont identify with him or her. The reason? Well, we all know ourselves and we all know that were far from perfect (although not everyone admits that).We all are flawed and thats what makes us human, so your protagonist needs flaws, as well. Maybe your protagonist worries too much about what others think, so she goes out of his way to appease someone she shouldnt appease? Or maybe your protagonist hits the bottle too much and gets sloppy on the job while facing a battle with alcoholism? However you do it, ensure that your characters have real flaws that help readers identify with them on some human level.Real people have a backstorySit a group of writers together in a room and youll have a room full of interesting people. However, let those writers start telling where they came from, how they grew up, who their first love was, their religious background, and the one thing theyre most embarrassed about having doneâ€"youll then have a room riveting stories and characters. And thats exactly what needs to happen to the characters you create.Providing your characters with a backstory gives them added dimension . They become more than a name, a face, a career, and the clothes they wearâ€"they become human. We see them as so much more because in knowing their backstory, or at least the highlight reel of it, we now have a greater understanding about why they act a certain way, what their motivations are, or what makes them tick, and these are all important qualities that a writer must relate to build a strong, dynamic character.Real people make mistakesAnother unquestionably human trait we all have is that we make mistakes. Those of us who claim otherwise are fooling no one but themselves. This is why its important to give your character limited access to knowledge of whats going on around them, or even a tendency toward a certain mistake that is a core element of their personality.Alternately, one of the best ways to have your character make mistakes is to put him or her in a situation that would be out of almost anyones depth. Doing so adds humanity and gives your reader a sense of empathy for the character, knowing that it would be a tough situation for anyone to face, and thus one thats prone to elicit mistakes. Your reader will immediately recognize the characters limitations (because weve all faced similar ones in situations out of our depth) and in doing so, see the characters humanity, as well.Real people have quirksYour character should have traits and quirks that add dimension to him or her. Beyond eye color, ethnicity, job or title, your character needs depth of emotion, physicality, personality and spirituality. Since the best writing is that which aims to show rather than tell, this article on mannerisms that will bring your character to life goes into extensive detail about how to show your characters traits, without resorting to telling your reader outright.For example, if your character has a tendency to lie or not tell the whole truth, he might pause while speaking a lot, or offer unnecessary details. If your character has social anxiety, she might kee p her arms crossed defensively or chain smoke while out in public. Or maybe your character has narcissistic traits, so he takes a lot of selfies, or waits for someone else to do tasks he should be doing himself. These are all ways to add character quirks and traits throughout your writing and add dimension to the characterâ€"even if that dimension isnt always positive.Real people face conflict and it changes them (for better or worse)Since the definition of a dynamic character is one who changes in the face of conflict, its important to understand the role that conflict plays in developing such characters. Without doubt, Cormac McCarthys The Road is a great example of how this is done.The Road follows the journey of a father and son in a post-apocalyptic landscape as they struggle to survive in the face of a decaying world (man vs. nature) and cannibalistic gangs or bloodcults (man vs. man). The father must also deal with his role as protector for his young son in a world that is di fficult for anyone to manage and survive, much less someone responsible for the life of a child (man vs. self).In Chris Gilberts study, Illuminating Character Identity, Motivation, and Conflict in Cormac McCarthys The Road, he observes how the character responds to each conflict and changes in the process. Of courseâ€"at the core of his observation is how the characters are decidedly and tragically human throughout these obstacles and the resulting changes. He writes:[The Road] provokes questions about human motivation or, more essentially, human nature. Although other literary works take up this theme as well, The Road is unique in that it depicts the behavior of characters who are no longer informed and controlled by social institutions: there are no schools to learn in, no laws to obey, and no people to govern. In other words, this is a novel that suggests how humans behave when no one else is watching. Human nature is on blatant display, and more often than not, it is exceedingl y disturbing.Chris Gilbert, The English JournalGilbert mentions how he is often questioned why he chooses The Road to teach students about characterization, and his response is that these two figures, described as each others world entire, sustain an intensely uplifting relationship that captivates and transports the reader beyond the charred settings of the novel. In other words, they are a perfect study of how building a dynamic character, even in a devastating setting and plot, can be done. Or as Gilbert puts it, These two characters have provided me with invaluable opportunities to engage students in meaningful character analysis, critical inquiry, and self-reflection.Real people lose faithAlong the archetypical heros journey mentioned earlier, the hero faces what is known as the dark night of the soul. It is a moment of atonement, of recognizing the monster within, and coming to terms with what must be done to defeat it. Without this moment, the metamorphosis of selfâ€"the chan ge that is neededâ€"cannot occur. You can think of it as the moment when a caterpillar encloses itself in a cocoon to be alone and face the darkness.The humanity of your characters shines through most when they lose faith and experience the dark night of the soul. Photo by Edwin Andrade on Unsplash.In the same sense, when your characters go through this dark night of the soul, it is a moment that is both necessary and important for the character arc to happen. It is a moment of lost faith, of sadness, of mourning for what has gone and trying to find the willpower to move forward. For a character to become dynamicâ€"that is, to change over the course of the conflicts and narrativeâ€"he or she must go through this cocooning process and come out on the other side of it victorious. Its at the core of what creates a dynamic character and will inevitably move your character from merely interesting to completely memorable.

Relations between Men and Women in The Waste Land - Literature Essay Samples

In his poem â€Å"The Waste Land,† T.S. Eliot presents multiple relationships between men and women, both historical and of his own creation. The interactions that he describes allow the reader to infer how Eliot views relationships, sexuality, and gender. He presents relationships as dysfunctional while only focusing on their negative aspects. Through description of various couples, Eliot presents gender in a stereotypical fashion which allows the reader to gain insight into how Eliot views the sexes, especially women. Throughout â€Å"the Waste Land,† Eliot alludes to many historical events, mythical traditions, and literary works. He references three famous relationships that serve as a background for the relationships that Eliot creates and describes in â€Å"The Waste Land.† The first allusion presented is to Wagner’s opera â€Å"Tristan und Isolde.† In this work, Isolde is unwillingly engaged to a King, a man she does not love. She instead fal ls in love with a knight, Tristan. The play ends tragically; both lovers die rather than give up their love (Synopsis of Tristan und Isolde) Eliot also alludes to the relations between a King and his sister-in-law as described in Ovid’s â€Å"Metamorphoses† (fn 1, p477) King Tereus, upon being overcome with lust for his wife’s sister Philomela, drags her to the woods where he rapes her and then cuts out her tongue to silence her. Later, after her escape, she is changed into a nightingale (â€Å"Philomene†). A third and final reference from the poem is to Cleopatra. A woman in â€Å"The Waste Land† is portrayed as sitting on a â€Å"Chair†¦like a burnished throne,† (l. 77) which is described in the footnote as an adaptation of Shakespeare’s play â€Å"Antony and Cleopatra.† In this play, Mark Antony believes that his lover, Cleopatra, is dead and he therefore impales himself on his sword. Cleopatra, awakening from a sleep, discovers that her lover is dead and commits suicide by means of a snake bite (â€Å"Mark Antony†). In these literary allusions, Eliot presents three relationships that are associated with despair and violence. In the â€Å"Metamorphoses† and â€Å"Tristan und Isolde,† women are forced to be with men they do not love nor desire. All of the relationships involve violence and all end in tragedy. Examining the three relationships together gives the impression that any fleeting pleasure that relationships or love can bring will be insignificant to the ultimate violence, pain, and despair that is involved. The examples give the reader context for interpreting the relationships invented by Eliot in â€Å"The Waste Land† which are described in three sections of the poem: in a conversation between an aristocratic woman and her lover (l. 111-138), in a bar scene in which a woman gossips about her married friend (l. 139- 172), and in a sexual encounter between a ty pist and a clerk (l. 215-256). In the first of these relationships, a woman speaks to a man assumed to be her lover. The woman is of high social class. She sits upon a â€Å"throne† (77) in her house which is furnished with luxurious things. The woman is frantic and seemingly irrational during a conversation with her lover. We first hear her exclaim, â€Å"My nerves are bad to-night. Yes, bad. Stay with me.† (111) This gives the reader an initial impression of an emotional and frightened character. She continues by demanding that her companion speak to her and tell her what he is thinking. She repeats herself frantically in her attempt to get him to respond to her (l. 112-114). This suggests that the woman and the man have poor communication with each other. When the man finally speaks, he is calm and enigmatic. He says, â€Å"I think we are rats’ alley/ Where the dead men lost their bones.† (115) This contrast with the woman makes her seem out-of-control on account of her emotions, her â€Å"nerves.† She continues by asking, â€Å"What is that noise,† to which he answers â€Å"The wind under the door† (117). Again, the woman is compelled to speak because of her emotions, in this case fear. The man is calm and rational, recognizing the sound as merely wind. She continues to be frightened by the sounds she hears and continues to be reassured by the man, â€Å"nothing again nothing† (120). Throughout the dialogue between this aristocratic woman and her lover, she is compelled to speak and act because of her flighty emotions. She recognizes herself as the weaker of the two as she early on begs the man to stay the night. This section can be interpreted as Eliot’s perception and commentary on the differences between genders. The dialogue is revealing about Eliot’s perception of women, as the man is portrayed as calm and rational in comparison to the overemotional, irrational, and weak woman. The second relationship described in â€Å"The Waste Land† is the marriage between a man and woman, Albert and Lil. We are hearing about this marriage as the narrator, an unidentified woman in a bar, describes the advice she gave to her friend, the wife Lil. Albert is returning from war and while he was gone, Lil’s appearance became more ragged and unattractive. The narrator therefore rebukes Lil, saying, â€Å"You ought to be ashamed, I said, to look so antique.† (156) The narrator points out that Albert has â€Å"been in the army four years, he wants a good time† (148). The narrator is expressing the view that it is Lil’s duty as a wife to be sexually available to her husband. If she is not willing to satisfy his sexual needs, or if she has not kept herself attractive enough to be desired by her husband, he is allowed to seek sexual satisfaction from other women. The narrator reminds Lil of this by pointing out â€Å"if you don’t give it hi m, there’s others will† (149). Lil attempts to defend herself by explaining that her deteriorating appearance was the result of pills she took to induce the abortion of what would have been her sixth child, â€Å"It’s them pills I took, to bring it off, she said† (159). The narrator implies that during the labor of the birth of Lil’s last child, she â€Å"nearly died† (160). It therefore seems understandable that Lil is not enthusiastic about the prospects of another birth. This does not sway the opinion of the narrator who asks, â€Å"What you get married for if you don’t want children?† (164) The narrator therefore presents the view that even if a woman’s life is in danger, this does not excuse her from her womanly duties of pleasing her husband sexually and consequently bearing his children. The opinion of the narrator, which may or may not be Eliot’s, is a commonly held societal view, especially in Eliotâ€⠄¢s time. Married women are expected to serve the sexual needs of their husbands. They are expected to bear children, regardless of their personal desire for children or the threat that giving birth posed to a women’s health in that time period. Reducing a woman to a means for men’s sexual gratification and as an incubator for his children is extreme objectification. Philomela was equally objectified by her rapist, who viewed her as a means to gain pleasure and not as a human being. The marriage between Lil and Albert, which appears to be loveless, is also reminiscent of the forced union of Isolde and the King, in which Isolde was being forced into a marriage with a man she did not love. In the final relationship discussed in â€Å"The Waste Land,† a blind prophet named Tiresias describes a sexual encounter between a female typist and a male clerk. A woman sits alone in her house, preparing a meal. A man enters. Although he notices that the woman is â€Å"bored and tired,† he still attempts to engage her in sexual activity (236). The encounter begins somewhat lovingly, with the clerk engaging â€Å"her in caresses.† (237) These advances are described as â€Å"unreproved, if undesired† (238). Seeing that the woman is not going to object, the man, â€Å"assaults at once† (239). In this situation, the man is only thinking of the pleasure he will receive from the woman and has virtually no other concern for her once he has gained her consent. It does not bother him that she does not desire him or the sexual act. In fact, he â€Å"makes a welcomes of indifference,† which suggests that he would rather her be disinterested (242). The man sees the woman solely as a sexual object, put in place for his sexual gratification. He has no desire to have an emotional connection with this woman, nor does he care whether she is receiving pleasure in return for his. When he leaves, he â€Å"bestows one final patronizing ki ss,† which is a condescending and demeaning gesture to impose on someone that was just used by you as an object (246). The woman is portrayed as unconcerned with this series of events. She thinks to herself, â€Å"Well now that’s done: and I’m glad it’s over.† (252) The narrator of this scene is the blind prophet from Greek mythology, Tiresias. He had lived for some time as both a male and a female. Because of his knowledge of both sexes, Eliot describes Tiresias as, â€Å"the most important personage in the poem, uniting all the rest† and says that â€Å"†¦the two sexes meet in Tiresias. What Tiresias sees, in fact, is the substance of the poem.† (fn 7 p481) Tiresias’ account of the sexual act between the typist and the clerk is central to understanding the gender relations that Eliot is presenting. Tiresias comments that he â€Å"perceived the scene, and foretold the rest / I too awaited the expected guest.† (229) This suggests that this scene between two â€Å"lovers† is one that Tiresias has seen, and most likely experienced, before, â€Å"And I Tiresias have foresuffered all/ Enacted on this same divan or bed.† (244) If the scene is a predictable one, it must be fairly common. Therefore, Eliot could be presenting the scene with the typist and the clerk as an archetype for relationships between men and women.This scene portrays distinct gender roles that are thought of as socially acceptable. The man, like the husband Albert in the previous example, is supposed to take whatever he wants, sexually, from the woman he is dominating and the woman is supposed to let these things happen to her without complaint. Parallels can be seen between this type of domination of man over woman and in domination in the form of the rape of Philomela. She too was not allowed to complain or talk about her encounter. Her rapist ensured this by cutting out her tongue, therefore disabling her from sp eaking of what he did to her. In all three of these cases, the woman is objectified with the result of her being viewed as only a sexual object. The violence in the cases of all three of the historical relationships is also mirrored in the typist scene; the man â€Å"assaults at once† even though the woman is not objecting or fighting him. This sudden, violent image is not as dramatic as the violence seen in the historical relationships, yet it is telling that it is included at all. Eliot’s description of the aristocratic woman might offer insight into how or why domination of women occurs. The woman here, whom Eliot presents stereotypically, is weak and is dictated by her emotions. She is obviously inferior to her calm, intelligent companion.The purpose of the women in both the historical relationships and those found in the poem is foremost to satisfy men and to be sexually available to them. This dehumanizes the women in these relationships to an extreme degree. The three relationships in â€Å"the Waste Land† are presented as loveless, sometimes violent, and dysfunctional. The ultimate impression is that relationships between men and women are bound to fail, and lead to despair or violence. BibliographyMark Antony. Oracle ThinkQuest Library.

Are indoor plants adapted to get rid formaldehyde, Sipin, Elly Lorreta one of the noxious wastes commonly found at home 002348-019 nowadays? 1.0 Introduction I did further research and found out that indoor air pollution phenomenon has urged the NASA (National Aeronautics and Space Administration) scientists to study the functions of plants to provide clean indoor air. NASA has become the pioneer towards this research and recently has been widened by many other associations like the Wolverton Environmental Services, Inc. endorsed by the Plants for Clean Air Council in Mitchellville, Maryland[1]. Don’t waste time! Our writers will create an original "Indoor plants" essay for you Create order Research done by NASA has found out that there are certain plants that have the function to purify the air in a building[2]. They detoxify the existing toxins and pollutants which originate from the things used in daily activities nowadays; fabrics, detergents and also furniture. These pollutants can be classified into three common indoor pollutants according to the list of indoor contaminant that are currently present. There are benzene, formaldehyde and trichloroethylene. (TCE)[3] Plants use the concept of transpiration to work onto this problem[4]. As the vaporized chemical enters the stomatal opening on the leaves of the indoor plants, they are either broken down directly or be sent downwards; down to the root system of the plants.[5] The presence of colonies of microbes at the root system breaks down various kinds of unhealthy compounds; in this case the indoor pollutants, and absorbs them as their source of food[6]. As for the mechanism of transpiration to remove the pollutant, water vapour that is liberated by the leaves of the plants will mix with the air in the atmosphere. Convection of air leads to the movement of the atmospheric air that is contaminated with the vaporized chemical downwards to the base of the plants. I chose 6 types of plants to be experimented by one fixed type of pollutant; formaldehyde. It is normally used in the production of grocery bags, facial tissues, waxed paper, waxed paper[7] and produced by tobacco products, gas cookers and open fireplaces.[8] In the experiment, this chemical is predicted to be absorbed by each plant. Plant that absorbs the chemical the most would be the efficient plant to be included in places mentioned before. 2.0 Aim To study the effect of plants transpiration towards the acidity and mass of formaldehyde in a transparent chamber. 3.0 Planning and method development Firstly, a chamber must be set up to place plants chosen. A pot of selected plant is placed into each chamber. 6 types of plants were chosen, therefore 6 chambers must be created. To make sure that air, sunlight and water could be continuously supplied, I decided that the chamber must be transparent, and there are holes to let air enters. The material that I chose is transparent plastic so that holes can be poked, the wall of the chambers can be flipped to water the plants everyday and plants get sufficient sunlight. I selected formaldehyde as the pollutant to the plants. In each of the chamber, I included formalin of the same amount in a beaker and let it evaporate in the chamber. As formalin CH2O, is a reducing agent[9], therefore it has the ability to release its hydrogen.[10] The more hydrogen ions present in it, the greater the strength of the acid. When evaporation of formalin happens continuously, there will be less in quantity of hydrogen atoms in the aqueous solution. Thus, the acidity of formaldehyde could decrease through evaporation; pH of the formalin increases. So, the pH of the formalin is ought to be checked for every interval of two days. Because concept of evaporation is used, it is for sure the volume of the formalin will reduce. The most effective method to measure this is by getting the mass decrease. I took the reading of the mass of formalin for every interval of two days. I decided to take note on the external condition of all the plants so that analysis on that can be don e to find its relativity with formalin. 4.0 Hypothesis My prediction is that indoor plants have the ability to get rid of formaldehyde, one of the noxious wastes commonly found at home nowadays by absorbing the chemicals through their microscopic openings perforated on their leaves; the stomata[11]. As the chemical evaporates, the molecules of the chemical are absorbed by the plants by gaining entrance through the stomata. These plants transport the absorbed chemical to their root system along the xylem of the plants to be broken down by the microbes present at the roots.[12] As formalin acts as a reducing agent, release of hydrogen could occur. Through evaporation of formalin, there will be less hydrogen atoms could remain in the aqueous solution. Thus, it is possible for the decrease in mass and increase in the pH of the formalin to occur when indoor plants are available. 5.0 Methodology 5.1 Variables a) Independent: * Types of plants chosen to be experimented There are variety types of plants chosen in order to know whether the hypothesis could be accepted. They are Boston fern (Nephrolepis exaltata Bostoniensis), Janet Craig(Dracaena deremensis), Florists mum(Chrysanthemum morifolium), Kimberly queen fern (Nephrolepis obliterata), Snake plant or mother-in-laws tongue (Sansevieria trifasciata Laurentii), Himalayan Balsam (Impatiens glandulifera) altogether. Himalayan Balsam (Impatiens glandulifera) acts as the control of the experiment to show its less in efficiency to absorb the toxin. Some plants have no ability to absorb the chosen toxin as good as in some indoor plants. b) Dependent: * The rate of absorption of formaldehyde The rate of absorption of formaldehyde is taken as the decrease in mass of formalin over time. This is documented for every interval of two days. Other than that, the acidity of formaldehyde in each chamber is also noted. This is done by using pH paper and pH meter to indicate the change in pH. The pH of the formalin in the chamber is recorded to see the pattern of change in acidity. c) Fixed: * The type of toxin chosen; formaldehyde Liquid formalin is selected to be one of the fixed variables in this experiment so that the analysis of the change in acidity can be done easily. More than one type of pollutant will promote confusion while conducting the experiment as the characteristic of one pollutant differ from one to another. Formalin is the aqueous state of the chemical formaldehyde and the concentration of the liquid formalin is 100%. I made the volume and the concentration of liquid formalin the same in every small beaker included in every transparent chamber. It is important to do so because the pH of the chemical and its mass are to be checked every 2 days throughout the duration of the experiment. The initial pH of the chemical is 3.510 while the initial volume of the chemical is 10 0.5 ml making its mass to be 10.19 0.01 g * The estimated size of the plants chosen The chosen plants are of the same size. There is no specific measurement for the plants sizes so therefore, the size is depending on the experimenters justification by fixing the number of leaves present in every plant chosen. This is due to the mechanism of the absorption of the chemical formalin happens through the microscopic opening present on the leaves; the stomata. It is therefore can be predicted that more tiny opening present on the leaves, the more effective would the rate of absorption be. I decided that the total number of leaves is approximately 15-20 leaves depending on the how broad the surface of the leaves is. * The size of the pyramidal transparent chamber The size of the pyramidal transparent chamber is to be made constant by using the same size and number of transparent plastic bags. The size of the plastic bags is 23cm x 38cm and they are cut into same shapes to fit it with the skeleton of the chamber. The base of the chamber is triangular in shape and constant with the area of (50cm x 50cm). 5.2 Materials MATERIALS QUANTITY JUSTIFICATION Formalin 120ml Formalin acts as the toxin in the experiment. Tap Water 5 litres This is used to water the plants everyday for 2 weeks duration. 5.3 Apparatus APPARATUS QUANTITY JUSTIFICATION Boston fern (N. exaltata) 1 pot These are the plants chosen to determine their effectiveness to absorb the formalin. Janet Craig (D. deremensis) 1 pot Florists mum (C. morifolium) 1 pot Kimberly queen fern (N. obliterata) 1 pot Snake plant (S. trifasciata) 1 pot Himalayan Balsam (I. glandulifera) 1 pot pH paper 1 box To check the acidity of formalin every 2 days. pH meter 1 To determine the pH of the formalin every 2 days. Disposable plastic cups 24 To be the base of the pyramidal transparent chamber. Plastic and bamboo chopsticks 54 To be the poles of the pyramidal transparent chamber. Electronic balance 1 To measure the decrease in mass of the liquid formalin for every 2 days. 50ml beaker 6 To place the liquid formalin in each chamber. 50ml measuring cylinder 1 To measure the amount of formalin in each 50ml beaker. Transparent plastics for packaging (23cm x 38cm) 1 pack To become the cover of the chamber. 5.4 Methodology to prepare a chamber for the plant A chamber has to be invented to place the chosen plants, considering the needs of those plants to get sufficient sunlight, air and water. I chose transparent plastics and attach them together to create a pyramidal transparent chamber. Holes were also poked to allow air move into the chamber. I included nine chopsticks to be the poles of chamber. A pole comprised of 3 combined chopsticks. To increase its stability, I poked a hole onto the bases of three disposable plastic cups and inserted the chopsticks into the holes. 5.5 Methodology to determine the change in acidity of formaldehyde After the chamber was set up, I prepared the solution of the toxin chosen; formalin.in a 50ml beaker. 10 0.5 ml of the chemical in each beaker was measured using 50ml measuring cylinder. 6 transparent chambers were set up to place 6 types of plants which were the Boston fern (N. exaltata), Janet Craig (D. deremensis), Florists mum (C. morifolium), Kimberly queen fern (N. obliterata), Snake plant (S. trifasciata), and Himalayan Balsam (I. glandulifera). All the 6 chambers contained different pots of plants and 10ml of formalin in a 50ml beaker. At intervals of 2 days, the mass of the formalin was recorded. The procedure to get the mass of formalin in each chamber was as follows; * Take the reading of the mass of 50ml beaker before filling in the formalin by using electronic balance. Repeat the steps 3 times in order to get the average reading. * Weigh the 50ml beaker containing formalin by using electronic balance. Repeat the procedure 3 times in order to get the average reading. The reading of the mass of the formalin + 50ml beaker at intervals of 2 days was recorded. The mass of the formalin was determined by subtracting the average value of the mass of formalin + 50ml beaker with the average mass of the 50ml beaker. The pH was again checked by using pH paper and also pH meter for 2 weeks. The change in colour of the pH paper and the reading of the pH meter were noted and documented. Each of the plants in the chamber was watered once a day using tap water. The amount of tap water must was 20ml per watering and watering time was at 10.30 a.m and 4.00 p.m. every day. Condition for each of the plants was observed for interval time of 2 days. All of results were recorded in a table. 5.5.1 Precaution 1. Beware while handling formalin because it is a dangerous chemical. Since a high concentration of formaldehyde will be used in the experiment, [13]it may cause burning sensation to the eyes, nose and lungs. Thus it could result in allergic reaction because of formalin. 2. Be cautious when building the pyramidal transparent chamber especially when dealing with the bamboo sticks. Avoid any sharp splinter of the bamboo stick from piercing into the skin. 6.0 Data collection TABLE 1: THE pH of FORMALIN IN EACH TRANSPARENT CHAMBER WITH DIFFERENT PLANTS IN 14 DAYS Transparent chamber containing plants Value of Ph of formalin in each transparent chamber according to number of days 2 days 4 days 6 days 8 days 10 days 12 days 14 days Boston fern (N. exaltata Bostoniensis) 3.510 3.550 3.570 4.020 4.130 4.260 4.310 Janet Craig (D. deremensis) 3.510 3.570 3.580 4.020 4.070 4.210 4.430 Florists mum (C. morifolium) 3.510 3.570 3.590 4.120 4.200 4.320 4.620 Kimberly queen fern (N. obliterate) 3.510 3.510 3.520 4.010 4.030 4.050 4.110 Snake plant (S. trifasciata Laurentii) 3.510 3.370 3.360 4.030 4.030 4.030 4.030 Himalayan Balsam (I. glandulifera) 3.510 3.370 3.370 3.350 3.350 3.350 3.350 Note: The pH of formalin in each beaker was checked at the same interval to ensure that none of the formalin being absorbed more by their respective plants.

Therefore, the table of mass of formalin for a duration of 14 days is made as follows. The formulation to calculate the mass of formalin in each beaker would be; Mass of formalin= [(Average mass of formalin+50ml beaker)- Average mass of 50ml beaker] TABLE 7: MASS OF FORMALIN IN EVERY 50ml BEAKER CONTAINED IN TRANSPARENT CHAMBER WITH DIFFERENT TYPES OF PLANTS Transparent chamber containing plants Mass of formalin 0.01g [(Average mass of formalin+50ml beaker) Average mass of 50ml beaker] Day 2 Day 4 Day 6 Day 8 Day 10 Day 12 Day 14 Boston fern (N. exaltata) 10.170 9.750 9.430 9.240 8.690 8.430 8.170 Janet Craig (D. deremensis) 10.120 9.730 9.520 8.740 8.240 8.160 7.790 Florists mum (C. morifolium) 10.150 9.820 9.560 8.760 8.430 8.150 7.340 K. queen fern (N. obliterate) 10.180 9.840 9.630 8.760 8.430 8.150 7.450 Snake plant (S. trifasciata) 10.120 9.830 9.630 9.100 8.540 8.340 8.180 H.

Balsam (I. glandulifera) 7.4 Mass and percentage of formalin absorbed The initial average mass of the 10ml formalin in the 50ml beaker is 46.980 0.01g and the average mass of the 50ml beaker alone is 36.790 0.01g making the mass of the 10.000 0.1 ml formalin poured in to be 10.190 0.01g. From the data, there is a decreasing pattern of the mass of the formalin in the 50ml beaker. The percentage of decrease in mass of the 10.000 0.1 ml formalin in 14 days of time in respective transparent chamber of plants can be determined. Before that, the mass of formalin absorbed in all the 6 transparent chambers must be d up.

The mean difference is not significant. 7.6 Analysis on mass of formalin From my prediction, only the indoor plants could eliminate indoor pollutants; as in this case the chemical formalin. While the outdoor plants are unable to do so. But I found out that decrease in mass of formalin in the entire 50ml beakers that contained the chemical is influenced by the ineffectiveness of the transparent chamber, which therefore rejects the theory that indoor plants transpiration alone could remove the pollutant. The ineffectiveness is referring to the external air movement that causes evaporation of formalin. According to the data processed, the percentage of formalin absorbed by each of the plants shows a very close difference to one another and it is irrelevant to assume that all the formalin that was lost was via transpiration. Further research was made to explain these big differences. I concluded that the difference in rate of transpiration in plants affect the rate at which volume of formalin is decreased. Thus, the greater the transpiration rates of a plant, the better quality of air it produces. My assumption on this is because of the availability amount of water vapor that could be emitted out by the leaves of the plants is great when the rate of transpiration of a plant is high. This enables more mixing of the water vapor in the atmosphere with the vaporized chemical. This means, there would be more food that is available to be broken down by the microbes at the root system of a plant. Of all the six plants chosen to be experimented, only 4 of them have high transpiration rates. They are Janet Craig (D. deremensis), Boston fern (N. exaltata), Kimberly queen fern (N. obliterate), and Florists mum (C. morifolium)[14]. The other two plants which are Snake plant (S. trifasciata) and Himalayan Balsam (I. glandulifera) have a much lower rate of transpiration when compared with the 4 plants. 7.7 Analysis on pH of formalin Formalin is acidic in nature and there should not be any change in pH of the formalin in the beaker because generally, a buffer; carboxylic acid is present in formalin.[15] With the buffer, the solution would be able to resist any change in pH even though there is any external factor that could alter the pH of the solution. Hence, the pH should remain constant. But since there is a change in the value of pH of the formalin contained in the 50ml beaker in all of the 6 transparent chambers, I then make an early assumption that the carboxylic acid that is contained in the solution does not buffer.[16] That was why the pH value of the formalin in the beaker in all of the 6 transparent chambers increased throughout the 14 days duration of experiment. There must be an external factor present in the chamber that affected the acidity of the formalin. Throughout my findings, I found an explanation for this. Formalin acts as a reducing agent.[17] Thus it can undergo oxidation which could relea se its hydrogen.[18] As formalin evaporates, it is being oxidized to become CHO+. The hydrogen would then combine with the water vapour emitted by the plants via transpiration; from H2O, becoming H3O+. These ions which are available in the air would be fixed by the microbes at the roots of the plants, becoming the source of food for the plants. 7.8 Analysis on the external condition of plants The external condition of the plants becoming worse as the experiment was carried out. Alteration of the colour of the edge of the leaves form green to yellow[19] and brown[20] and wilting of flowers[21] was due to the insufficient of water. Thus, it can be said that when the plant is lack of water, it would not be efficient in removing pollutants. The plants got dried up; changing colour from green to brown thus there was no stomata opening because the guard cells die. Eventually, the transfer of chemical downwards to the roots of the plants will not happen. It can be assumed that for plants that got dried up towards the end of experiment that the colour of the leaves started to become brown, the rate at which the mass of formalin decreases was not mainly supported by the process of vaporized chemical being absorbed through the stomata. Perhaps the colonies of bacteria are still present at the roots of the plants with this condition but the rate of decrease of formalin mass is reduc ed, not as rapid as the initial rate. 8.0 Conclusion From the data obtained, I conclude that one of the observable changes in the quantity of the formalin is the mass. This is influenced by the evaporation of the formalin. The percentage of formalin that could evaporate is minimized by having the transparent chamber to cover the plant and 10ml of formalin which means the evaporation of formalin was not greatly affected by wind movement. It is therefore possible for chosen indoor plants; Janet Craig (D. deremensis), Boston fern (N. exaltata), Kimberly queen fern (N. obliterate), Florists mum (C. morifolium), Snake plant (S. trifasciata) and Boston fern (N. exaltata) to remove the toxin, formaldehyde as there is quite large decrease in the mass of the formalin. Though Snake plant (S. trifasciata) does not have a high transpiration rate, it can still remove formalin quite large in quantity. I believe that this is affected by the factors such as number of holes poked onto the chamber, the external wind movement and some more mentioned in t he evaluation part. (Please refer to 9.0) As for Himalayan Balsam (I. glandulifera), an example of outdoor plant, it is probably able to remove indoor pollutant but just in small percentage as seen in the ranking done in the data processing, this plant provides the lowest quality of air in the chamber due to contamination by the pollutant formalin. It could just remove formalin for about 7.160% in 14 days duration. Besides, the only plant that experienced a rapid external change was Himalayan Balsam (I. glandulifera). The edges of the leaves become brown on the twelfth day. One of the closest possibilities is due to the failure of the experimenter to follow the period of watering everyday that it received less water.[22] It might be due to a very small surface area of this plant that it was deficient for it to cope with the concentrated amount of formalin in the chamber added as before the experiment was conducted properly, I have tried including the same amount of formalin in a chamber containing less than 10 leaves and the same result occurred during the 8 day interval. Referring to the T-test in table 11 to table 25, all of the t- values were rejected because it lied in the critical region. The null hypothesis selected suggested that there was no significance between the differences of mass decrease between the plants. For the data to correspond with the predicted result, null hypothesis should be accepted. But because the pattern of formalin mass decreasing was too small from one interval to another, some of the values of standard deviation obtained are zero. That was why the mass differences between the plants are not significant when the t-values are all less than the critical value at 5% level which is 4.300. Thus, the null hypothesis stated that the mass differences are not significant to each other. This did not indicate the unreliability of the data but it showed that limitations and weaknesses were present in the experiment. There is an increase in pH of the formalin and the pattern somehow shows that the acidity of the chemical has already decreased. The assumption made through the research made for this experiment was indoor plants have the ability to get rid of formaldehyde, one of the noxious wastes commonly found at home nowadays. 9.0 Evaluation There were several weaknesses in the procedure throughout the experiment. I have come out with some suggestions on what to be improved on the aspect of methodology and the aspect of apparatus and materials used so that the experiment would give a reliable result when it is repeated in the future. Regarding the technique to measure the acidity of chemical formalin, I found out that it was unreliable. The pH meter sometimes failed to function well. Sometimes, pH meter detect acidic chemical to be having a pH value more than 7. It is highly suggested to use colourimeter because this instrument could give the exact concentration of hydrogen, H+ in the solution[23] enabling the calculation of its pH by using the following formulation; pH= -log10 (concentration of H+ ions) Next, there was failure to exactly follow the watering time for all plants in the chamber which eventually affected the external condition of plants. Thus, a time table has to be prepared in the future so that the watering time is made standard each day. Other than that, there was a pot of plant with one of its leaves had fallen into the beaker containing formalin. This should not happen because it could have left effect onto the acidity of the formalin. Place the beaker of formalin further from the pot of plant in the chamber so that neither leaves nor flowers would fall into the beaker. Lastly, number of holes poked onto some of the transparent chambers which were not fixed. In my opinion, this is one of the causes of inefficiency of the chamber. The more holes present, the more rapid would the evaporation of chemical be. Therefore, fix the number of holes poked. For a better result, use a square plastic aquarium being inverted with 2 square polystyrene as its base. This would allow less movement of air but able to provide oxygen for the plants in the camber. All in all, the hypothesis of the experiment is accepted. It is proven that the indoor plants are able to remove indoor pollutants while plants that are not indoor plants are able to remove indoor pollutants with a lower rate. Thus the public can now use this concept to provide good air quality at homes.
