Impact of Flow Rate on Water Quality of the River Yare Lab Report

Impact of Flow Rate on Water Quality of the River Yare - Lab Report Example This problem has been mostly alleviated through the removal of phosphorus from these sources before dumping. However, the current concern that is most pressing in regards to the health of the river Yare are the changes in its flow rate that have come as a result of human activity. The present study is meant to investigate the biotic scores from two distinct sampling sites, a "Fast Flow" area and a "Slow Flow" area, and to determine if they are influenced by factors other than organic pollution In order to assess the environmental impact of changes in flow rate velocity on the river Yare, we employed the Biological Monitoring Working Party method (see BMWP). Two sample sets have been collected. The first set was collected in an area of the river designated "Slow Flow" and a second set from a "Fast Flow" area. The area of the river considered as Slow Flow had the following characteristics: meandering, reed lined, no organic matter on Benthos, sediment sand, gravel, no visible flows, mixed banks, clear water, no algae, 0.5 m/s surface velocity, 5 m width. The characteristics of the Fast Flow collection area had the following characteristics: shallow 15-20 cm, stony riffle, surface speed 1 m/s, steep sides, sloping sides, deciduous trees on sides, fallen leaves in water, some green weed in Benthos, water is clear. In this field study, the presence of a variety of species i... Since the mayfly is the most sensitive to the effects of pollution, it is given the rating of 10. Worms, which are relatively insensitive to pollution, are given a score of 1. The total score accumulated from many samples is then assessed in relation to previous scores. Results The raw individual data for the Slow Flow collection as well as the Fast Flow collection is shown in Figure 1. Pooled group data is shown in Figure 2 for both Slow Flow and Fast Flow sampling. Results of the SPSS analysis of the raw individual data is shown in Figure 3. For the Slow Flow data, p=0.00 and p

Representations of Space in Art Movements

Representations of Space in Art Movements Spatial representation is a complex subject involving the scientific technique of perspective and incorporating different periods of art. Discussion of this topic allows for an analysis of both the random and deliberate forms of spatial representation, the ever-changing artistic conventions underlying this representation, and an examination of artists who have challenged this technique. Representation, defined as, the description or portrayal of [†¦] something in a particular way is utilised by artists to produce works that resemble, to varying degrees, their chosen subject. The techniques of spatial representation can be seen in a large number of artworks, such as sculpture, painting, photography, and collage. Composition, defined as, the artists method [†¦] of deciding what to put in and what to leave out in order to make an effective picture remains the most prevalent of these techniques. Both horizontal and vertical forms of composition provide the artist with a powerful means of communication with the spectator. Size is also important in spatial representation and is exemplified in Duccio di Buoninsegnas The Rucellai Madonna , where [†¦] la superposition ou lalignement des figures correspondent à   un ordre hià ©rarchique. Evidently, the more important figure was depicted as larger in early works of art. The varying scale of characters was used as an attempt at perspective. It has been said that the effect of space in a painting is [†¦] the creation of the illusion of three dimensions on a flat surface. Linear perspective, or single-point perspective, [†¦]was adopted as the standard way of representing spaceand works on the principle of orthogonal lines converging to a vanishing point'(see note 5 above), giving the illusion of depth, and thus three dimensions to a painting. Linear perspective was challenged by aerial perspective which utilises the principle of fading shades of colour and the increasing use of blue as the distance from the viewer increases. Aerial perspective can be observed in Turners Lake at Brienz, which uses colour to portray misty distances. La perspective tordue is another technique where le bison est reprà ©sentà © le corps de profil ou les cornes de face [†¦] qui rà ©unit deux points de vue, deux perceptions dans une seule et mà ªme figure . Although perspective remains an important tool, the interior and exterior representation of space needs consideration. In their works, artists can choose how much of the subject they wish to expose to the viewer. The utilisation of interior and exterior space can be seen in Vincent Van Goghs painting, La Chambre à   Arles (1888). Here, Van Gogh has painted a window, leading the viewers eye to the outside world. However, the viewers only connection with the outside world is through a picture of a landscape on the wall of the bedroom. It is also interesting to note the unusual use of the laws of perspective; there is no single vanishing point. Random spatial representation has long been a debatable subject. Frank Stella said, in 1986, the aim of art is to create space [†¦] that is not compromised by decoration or illustration, space within which the subjects of the painting can live. This quotation implies that space is represented in a very deliberate manner. However, the works of John Pollock were often said to represent space randomly as they appeared to have no degree of order to the viewer. It is also argued that when an artist chooses to create and represent space in an image, it creates another random space as a result. Although sculpture accommodates differing viewpoints, space can be represented randomly. For example, The Large Head, by Naum Gabo creates the illusion of a solid structure when viewed head on. However, when viewed from the side, space is represented differently, with the sheets of metal forming a random structure. Whilst a completely random representation of a space is rare, and it has been said that tout point de vue est un choix signifiant: il correspond à   une intention, implying that no art can ever be random, artists have often embraced the technique of Apparent Randomness. This technique is seen in Picassos Guernica and involves the artist deliberately positioning certain objects to create the illusion of randomness. Jackson Pollocks Abstract Expressionist painting, Autumn Rhythm, highlights the chaotic atmosphere which led to an assumption of randomness. Due to the disorderly pattern, the public felt that Pollocks spatial representation was far from deliberate. However, a close analysis revealed an underlying pattern. This technique is also shown in Jean Miros, The Dialogue of Insects, further emphasising how artists represent space deliberately. A further artistic movement which utilises the apparently random positioning of objects is Cubism. Pioneered by Picasso and Braque, Cubism was concerned with the deliberate interaction between geometrical shapes to create planes and lines of vision. Despite its random appearance, each shape was specifically placed. Picasso also developed the technique of collage. Collage is perhaps one of the most interesting examples of how artists choose to represent space. It is quite possible that the random appearance of a collage may have been created by an equally random procedure. However, some thought and calculation is often evident. This can be seen in Raoul Hausmanns, A.D.C.D, where different objects of different materials have been layered on top of one another in a precise manner. It is clear from the lines of an art work that some sense of order is displayed. Pierre Renoirs The Umbrellas shows how the use of repeated circles has created order within the crowd of people depicted. Line also gives rise to perspective. Alexander Rodchenkos Jeune fille au Leica demonstrates linear perspective, using the lines of shadows to lead the viewer to the vanishing point. Line and perspective are key examples of how artists represent space in a deliberate manner. Photography appears to capture life randomly through a lens. However, when a photograph is taken, the photographer has to make very deliberate decisions about what he wants to depict. In Russell Lees, Les mains dune fermià ¨re de lIowa, we see only the hands and lower body of the subject. This is a very deliberate action on the part of the photographer. Photography also clearly demonstrates field of vision and the use of plongà ©e and contre-plongà ©e.The space being viewed is represented far differently when viewed from a different angle. Although this compositional technique can often appear to be random, artists often employ it to convey meaning. An illustration of the multiplicity of points of view can be seen in Holbeins, The Ambassadors. This technique is also known as anamorphosis. The placement of objects must be decided very carefully to illustrate the passage of time in art. In Eugene Atgets Angle de la rue des nonnains dHyeres et de LHotel de Ville, the winding market street descending into fog, and the blurred figures in the foreground have been purposely captured in their positions. Artists must always work within frames, deciding what will be captured or depicted within them and what will be left unseen. This process appears to be far from the ideals of randomness. The variety of artistic techniques used to represent space leads to the questioning of the deliberateness of an artists work. Despite certain random spatial elements within a painting, sculpture, or photograph, it is evident that artists attempt to represent their chosen subjects with accurate spatial representation or deliberate attempts to illustrate randomness with geometric techniques. One can conclude that spatial representation has been used in a variety of ways to create works that appear both random and deliberate. Word Count: 1499

The Degradation of the Character of Macbeth :: GCSE Coursework Macbeth Essays

The Degradation of the Character of Macbeth  Ã‚   Shakespeare's tragic play, Macbeth explores the decline of the central character, Macbeth from a respectable warrior to a murdering and lying fiend. This change in character is a direct result of Macbeth’s unbridled ambition and greed. In act 1 scene 2 Macbeth is described as "brave", "valiant" and "heroic" and everyone admires him. King Duncan and his court receive news from the wounded Captain that the battle against the traitor and the rebel MacDonwald and his army was evenly balanced until Macbeth and Banquo in acts of outstanding courage and ferocity destroyed him and his troops, like "sparrows eagles, or the hare the lion". But as this occurs , reinforcements from the King of Norway and the traitor, the Thane Of Cawdor, counterattack Macbeth and Banquo " but all's too weak; for brave Macbeth well he deserves that name". However these two are not at all dismayed; but as the Captain is taken away to tend to his wounds, the outcome is still unsure. The Thane Of Ross arrives to report that, through the fighting spirit of Macbeth, Duncan's army has won a great victory " The victory fell on us". Duncan declares that the "most disloyal traitor" the Thane Of Cawdor is to be executed which is very ironic "Go pronounce his present death" and Macbeth "O valiant cousin! worthy gentleman!" is to receive his title and estates as a reward "Nobel Macbeth hath won". Although we haven't yet met Macbeth, whilst the battle is primitive and bloody the Captain's and Ross's descriptions emphasize an "heroic", even "epic" quality of Macbeth part of them. This is shown in the personifications such as "Disclaiming fortune", "valorous minion", and references such as "memorize another Golgotha". Duncan himself generously praises Macbeth, and the final epithet he gives is "noble". These quotes show that people and even the king have a very high opinion of Macbeth. The witches appear at the beginning and are highly ambiguous creatures- whether they are human it is debatable. The witches create a sense of mystery: they will meet when "the battles lost and won", which seems a contradiction. The fact that they are evil is show in their final couplet. According to them "Fair is foul, and foul is fair". Put another way this means: good is bad and bad is good. All of Act 1 scene 1 creates a very ominous atmosphere.

Gender in Bram Stokers Dracula Essay -- Bram Stoker Dracula Essays

Gender in Bram Stoker's Dracula During the Victorian Era, women struggled to attain gender equality by challenging the traditional roles that defined them. These women no longer wanted to remain passive and obey the demands of their husbands nor be domestic and the caretakers of their children. They strived to attain the role of a 'New Woman', an intelligent, liberated individual who was able to openly express her ideas (Eltis 452). Whereas some women were successful in attaining this new role, others were still dominated by their male counterparts. The men felt threatened by the rising power of women and repressed them by not allowing them to work, giving them unnecessary medications, and diagnosing them with hysteria (Gilman 3). When reading Bram Stoker's Dracula through gender lenses, this rising power, specifically sexual power, is apparent. After Dracula bites Lucy Westenra and Mina Murray (Harker), they are liberated from their conventional womanly roles and transformed into new sexual creatures; new be cause sexuality was usually ascribed to men. The men feel threatened by this blurring of the traditional, male defined gender boundary and therefore returned the women, by killing Dracula, to a manner that was prescribed as culturally appropriate for their sex (Hughes 86). This form of repression kept Lucy and Mina from attaining the role of the ?New Woman?. Before Dracula bites Lucy and Mina, they are passive, obedient, and domestic, but also have hidden qualities of the ?New Woman.? These ?New Woman? qualities are only shown to each other, never to the men. Lucy represents the societal mold of the female: sweet, beautiful, and attractive to countless men.

The Relationship Between Policy, Statutes, and Regulations in Environmental Law

Environmental policy is the official stance or statement by a government or organization which provides a framework for its environmental objectives. (C2E2. org, 2011)The US Government Environmental policy is contained in the National Environmental Policy Act of 1969 (NEPA). Congress declared under section 4331(a) of NEPA that it is â€Å"the continuing policy of the federal government†¦ to create and maintain conditions under which man and nature can exist in productive harmony, and to fulfill the social, economic, and other requirements of present and future generations of Americans. (U. S. Congress, 1969) Environmental statutes are the written will or act of the legislature with regard to expressing the stated environmental policy. (Lectric Law Library, 2011) NEPA functions in this capacity by enabling the EPA to promulgate regulations in order to set forth guidelines by which other agencies must comply in order to satisfy the intent of NEPA. Environmental regulations act as the forcing mechanism with which to gain compliance with the statute as set forth under the policy. Continuing to use NEPA as an example, the US Government environmental policy is contained in NEPA (the statute) which prescribes regulations that aim at protecting the environment. Most noteably, the EPA issued regulations regarding Environmental Impact Statements (EIS) and Environmental Assessments (AE) assess the possible environmental impacts of proposed government projects and there alternatives – and are required from all federal agencies. (US EPA, 2011)

Kill the Internet Essay

Kill the Internet-and Other Anti-SOPA Myths Essay The Article â€Å"Kill the Internet-and Other Anti-SOPA Myths† by Danny Goldberg introduces PIPA(Protect Intellectual Property Act) for online piracy on the internet. This situation is connected to the copyright piracy as well. The issue in this essay is the common problem of published articles and links being copied and pasted from people off the internet and getting credit for another person’s work. In this case I agree with the SOPA because copyright is not to be credited for those who don’t do their own work. To me, it is a guidance for help not coping. Coping someone’s work is not helping the situation and takes the away the opportunity of the author to get credit. One reason to my decision on agreeing is the leading affect of progressive voices and outlets of skillful writers work is being taken into someone else’s work. According to the Politics website, the legislation would allow copyright holders and the justice Department to seek court orders against websites associated with copyright infringement. To the legislative, they believe that the copyright holders chances of winning is not very high. They see coping as a threat to publishers and should be banned even if internet websites lose business. A second reason that got me to agree was a statement made by Clay Shirky’s assistant in the book The McGraw-Hill Guide. â€Å" Many believe that copyright isn’t coping if the creator doesn’t lose profit because nothing physical isn’t taken from them,† – Clay Shirky’s assistant. This statement is false reasoning because even if the authors profit isn’t lost, the fact that their hard work is being copied by someone else doesn’t make things alright. The publisher worked hard on the writing they published to the internet and it shouldn’t be taken advantage of. People need to realize that taking others work isn’t a very clever idea because your only hurting yourself by taking other people’s credit. It’s the same as someone taking a movie that a director worked hard to become public and then has to find out their credit was copied by another person and is being used or is being taken ownership  by that person. Because of this problem many websites are losing their businesses for links and articles of authors are declining their work to be on the internet. For this I believe the SOPA is making the right decision and should proceed in protecting the internet uses. All in all copyright should have been prohibited a long time ago. For those whose work is being taken out of context and losing credit isn’t fair. SOPA and PIPA industries should feel good about themselves for finally taking action and stopping internet copiers on the websites available to the people.

Progression of Humans

The Dawn of A New Day Preface The creation of man begins with † In the beginning, God created the heavens and the earth†. One sentence that if proven correct, depicts that a certain scientific theory taught generation after generation is completely and indefinitely ludicrous. If this sentence is wrong, various religions cease to exist. Ah, but does Christianity need to be proven? In our minds, the correct answer to this question is no, to believe is to see. But as human beings, sinners in the eye of God, to see is to believe.Now stay tit me here. As the mundane world revolves around the simplistic idea that happiness can be achieved by buying the world, certain people rise among the filth. Go-getters. Transcendentalists, if you may. These people are the true â€Å"Hipsters† among the conforming young generation set upon being differently the same. They are the people who pay little or no attention to the world of Consumerism evolving around them. They may be differ ent; hell they might even be bizarre. The point is that these are the people who change lives.They are the people that can truly make difference in this god-forsaken planet we call home. They may not be of faith, but they can be compared to the disciples of Jesus Christ. Now back in the day, the disciples weren't some group of â€Å"religious freaks†. They were not celebrities. They weren't even liked. These disciples were the people who stood up for what they believed in, facing both death and the fate of being cast away as outsiders. You see, it doesn't take much for change to occur. It Just takes a person who has the courage to partake in disorder.There are four point two babies born per second. One point seven deaths per second. As life goes on, 27 phones are sold per second. One point six cars produced per second, and 168 tons of foods are produced per second. Life goes by in seconds. Every minute you are aging. Day by day you are changing. An hour passes by, how many pe ople have died in that hour? The point of this crazy numbering is to show you how fast moments of your life pass you by. There is no way of knowing the exact moment of when your life will come to an abrupt stop. You will cease to exist.Life will end, as you know it. Will you be remembered? Will the memories your loved ones have from you be worth remembrance? The days you spend locked away from the majestic wonders of the world are limited. Live your life the way you want to live it. You only live one life, so you better make it worth living. The harsh reality of our situation on this planet is that one day it will be your time to go. Will you make a difference? As generations pass by, the improvements we make to society are crucial to the progression of humans.
