Relate the quotation selected to the theories of tourism and impacts and sustainability - Research Paper Example While this along with other such regions around the world are quickly becoming the must-watch hot spots of wetland destinations, it is essential to see how far the tourism industry is thriving on both improving the economy and protecting the marshes by sustainable maintenance. Since wetlands provide essential services such as water, food and energy, the indigenous people will have an urge to protect the swamp, mostly as part of their own tradition and culture (Chang 2010, p. 190). At the same time, tourism industry is interconnected with social, economical and environmental factors of the community. On the whole, tourism has the capacity to generate jobs and related businesses. Thus development in tourism needs to be sustainable, so that a) the viability of enterprises and activities can be maintained for a long term on the economic front, b) a greater respect for human rights, that is recognised with an impartial allotment of benefits to eradicate poverty, could be gained on the soc ial front and c) conserving and managing of resources, biological diversity and natural heritage become priority on the environmental front. As a matter of fact, sustainable tourism would promote a desire in the masses to enjoy green tourism, for example, conducting a series of elite interviews on why tourism is booming in Cuba, Jayawardene (2002. p 57) found that â€Å"the government’s focus on and attention to sustainable tourism development† was the main reason for the tourism flourishing in Cuba. It shows that tourist preferences are increasingly influenced by sustainability concerns; that is why, according to Taleb Rifai (Secretary General World Tourism Organisation), â€Å"today, ecotourism, nature, cultural adventure, rural and community tourism are taking the lead in the tourism markets and are predicted to continue growing more rapidly than traditional tourism products. Wetlands tourism is therefore uniquely placed in the evolving scenario of green tourismâ⠂¬  (2012). Considering the growing popularity of greener destinations, there is an urgent need of sustainability in wetland tourism management. The planning of policies and awareness rising on this issue needs to be focused on the potential value of the wetland tourism with regards to the economic benefit it can bring into the indigenous society. The study of the Fatt’an wetlands in Taiwan concludes by stating that awareness of the local people is the key to the success of any sustainable management program (Chang 2010 pp 198). However, many wetland examples around the world would reveal the risks and consequences of having unsustainable management in wetland tourism. Many countries have introduced wetland tourism policies, but they have not set sustainable strategies adequately recognising the role of wetlands. Hence, some of the African countries including Kenya, Namibia and so on were not able to yield the fruit of wetland tourism (Earth Watch). Similarly, the negative e ventualities resulting from unsustainable management of wetland might include the deterioration of the ecosystem due to various activities, which may also negatively affect the tranquillity of the wetland species

Philosophy of Hans Jonas Essay Example | Topics and Well Written Essays - 1750 words

Philosophy of Hans Jonas - Essay Example Hans Jonas studied the philosophy of biology and at some point made the whole theory belong to him, this resulted in many philosophers following suite. It is for this reason that the philosophy of biology has become an independent subject of its own and this was realized fifty decades ago. Hans Jonas’s thought of biology in terms of life and this made his work willingly easier. For him, life was not just a living presence but also a cognitive science of a living being. Many philosophers of biology ignored to cover the traditional mechanism of life in a living being and instead covered the theory of modern biology. Philosophy of Hans Jonas Hans Jonas discovered the phenomenal origin of life in relations to biology, and this quickly changed into a venture of philosophy. Hans Jonas justified the thought between God’s creation and the existence of life on earth. From the introduction of Deoxyribonucleic acid (D.N.A) to the study of psychology, biology has become an importan t aspect in life. Hans Jonas examined that the philosophy of biology can sometimes be interpreted in the same concept as theoretical biology. This is because of the mathematical concept involved in the study of medicine in theoretical biology. Hans Jonas made the study even more related to the philosophy of biology by using genes to examine both theories of biology. According to Hans Jonas, the main issue facing many scientists is doing a research on the living beings without the experimental exploitation. Hans Jonas stresses out that the main solution is putting across and explaining the individual rights to biological theories. The medical experts have attributed outbreak of various diseases to lack of human experiments. Hans Jonas examines the philosophy of biology and reflects on the justification of medical experiments on human beings. Hans Jonas also ponders on life as an experience that might have biological experiments of its own. According to him, not all aspects of life re quire biological attention as some human beings justify life as an experience. Though some philosophers have linked the two to biology, Jonas has come out to differentiate the two as stemming back to the traditional examination of biology. Hans Jonas has used this approach to differentiate the biblical theory of life from the philosophy of biology. Though Hans Jonas does not criticize the biblical concept attributed to life, he acknowledges the biological concept as an easier understanding of life. Hans Jonas has categorized life in three aspects and this has enabled many philosophers to understand biology more easily and as a result put it in their own understanding. Being is the first classification that Hans Jonas used to examine life. He acknowledged that without life, there would not be in existence any living being. He ponders this theory of life as a mortal tension between being and nonbeing. According to him, the idea of death causes trauma in the minds of every being. Birth is more an intellectual theory of life than death and Han Jonas examines that all beings would welcome the idea of birth more than death. Self and world is the second classification that Hans Jonas used to relate life to biology. Hans Jonas ponders into the idea that once an individual is born then he considers himself to be alone in this world. According to him, alone would mean owning your own life and not the physical self. He examines the fact that an individual has an access to his own life and therefore

Polycythemia Vera: Causes and Treatment

Polycythemia Vera: Causes and Treatment From the ancient times to the modern era of today where everything is said to be changed irrespective the good or bad, not only mankind had undergone an evolution but so as the diseases which is why new medical innovations are highly needed to counteract such dilemma. Diseases do not only invade a person externally but also can spread internally as well such as blood diseases. Blood diseases are diseases that involve the mechanisms, functions, site of production, and most importantly the components of blood. According to Hezy (2010), one of the major blood disease is polycythemia Vera, also known as erythremia, primary polycythemia, and polycythemia rubra Vera. Polycythemia Vera is a myeloproliferative rare blood disease in which the bone marrow produces excessive amount of erythrocytes and may also result in the overproduction of leukocytes or platelets causing the blood to be thicker and travels slower than normal. This is a very serious problem as sooner or later the person would suffer from heart attack or stroke as the possibility of having a stroke or heart failure increase by 80% if a person suffers from polycythemia Vera due to blockage of blood vessels. Although polycythemia Vera is considered a very rare disease, it still happens among us despite its low possibility. Therefore, treatments are highly recommended as it could be fatal or lead to another sort of diseases as well because a subset of patients with polcythemia Vera may progress to acute myelogenous leukemia or myelofibribrosis stated by ClinicalKey (2012). From the research of Ann Intern Med (2013), the statistics shown that polycythemia Vera can occur in any individual irrespective age or gender but it has been proven that is it more common among people with the age group of 50 to 70 years. In overall, polycythemia Vera is more prevalent in men than in women. According to Vanasse G., et al (2008), the data claimed from major commercial insurance payers in Connecticut and the Center for Medicare and Medicaid Services estimated that the number of patients with polycythemia Vera is 22 per 100,000 respectively for the age-standardized prevalence and it is also estimated that there is a total of approximately 65,200 patients with polycythemia Vera applying the age-specific prevalence to the entire US population in 2003 which is the first assessed prevalence of polycythemia Vera in the large US population. Moreover, Brian J.S., et al (2004) stated that a comprehensive review reported the incidence of polycythemia Vera to be 2.3 per 100,000 each year worldwide. After a thorough diagnosis, the seriousness of polycythemia Vera is underscored by the fact that the median survival for untreated symptomatic patients is about six months to one and a half year but for treating patients, the median survival can be surprisingly prolonged to about seven to fifteen years. Based on DoctorTipster (2011), there are a few factors that may increase the risk of developing polycythemia Vera. Firstly, aging is one of the unavoidable factors as the chances of developing polycythemia Vera grow with age. Normally people around the age of 60 years are more prone to this disease and it is hardly found in people who are under 20 years of age. Secondly, it is a fact that polycythemia Vera effects with predilection men and lesser in women by comparison. Thirdly, families with medical history is also one of the risk factors that can lead to polycythemia Vera. Most cases of polycythemia Vera are not inherited, it is associated with genetic changes that are somatic, means that they acquire during a persons lifetime and are only present in certain cells and not transmitted or passed down generally from parents to children. However, in rare instances family history of polycythemia Vera especially relatives are said to be the cause for the increase of risk for developing t he disease. In these families, the risk of developing polycythemia appears to have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means that one copy of an altered gene in each cell is sufficient to increase the risk of developing polycythemia Vera, although in these cases no causative genes have been identified but these people seem to inherit an increased risk of polycythemia Vera, not the disease itself. Last but not least, the environmental conditions or lifestyles also count as a risk factor as well as polycythemia Vera can occur due to different lifestyles or even different exposures to environmental conditions such as radiation. Exposure to intense radiation may actually increase the risk for the condition or even trigger the disease because the main reason for the development of disease is genetic mutation. Lack of exercise or unhealthy diet will only aggravate the body conditions as most of the people nowadays are already in bad shape because o f neglecting health care for work and stress. Pr Jean B. (2010), stated that the main source of determining an individual either with or without polycythemia Vera is based on whether the mutation occurred in the bodys genes which is the major cause of polycythemia Vera. Polycythemia Vera happens because of the presence of abnormal clonal stem cell expansion that suppresses the growth and maturation of normal stem cell which is a somatic mutation known as JAK2-V617F commonly in exon 14 of the JAK2 gene or in exon 12 which is less common. However, exactly what causes the mutation is still a matter of debate. The presence of a V617F or a mutation of the JAK2 gene can be diagnosed because the gene actually functions to make a protein that aids the body in producing blood cells and so there will be an elevation in the amount of white blood cells, platelets, hematocrit, hemoglobin, and most of all the red blood cell mass which is about 125% greater compared with the normal. As a result, the blood will become thicker and harder to pump which is very dangerous as it can relate to heart attack, stroke, and other health diseases. Almost all of the health problems associated with polycythemia Vera are caused by the blood of the individual being unusually thick due to overproduction of red blood cells in the body. The disease is more common in the elderly and can be either symptomatic or asymptomatic. TheFreeDictionary (2013), stated that normally there will be common signs and symptoms such as itching and severe burning pain in the hands or feet accompanied by a reddish and bluish colouration of the skin most likely on the face. Unfortunately, patients with polycythemia Vera are also likely to develop gouty arthritis. As the development of polycythemia Vera is rather slow, signs and symptoms might not show for years. Therefore, the disease is often found out when a blood test is done for other purposes. However, when the signs and symptoms are present due to the thickness of the blood slowing down the flow of oxygenated blood to all parts of the body and this will lead to many parts of the body unable to funct ion properly with insufficient oxygen. As a result, one may experience headaches, dizziness, blurred or double vision, shortness of breath, numbness, itchiness especially after bathing with hot water, fatigue, and more. Besides that, there are actually levels or phases where symptoms or effects are shown at various stages. The symptoms of the early polycythemia Vera may be minimal so it is not unusual for the disease to be discovered easily. Patients often experience symptoms like headaches, confusion or impaired memories, breathing difficulty, giddiness, vomiting, hypertension and much more which people would treat them like a minor or a common issue. In some patients early symptoms include unusual heavy bleeding from minor cuts, nosebleeds, pain in the bone, or stomach ulcers but there are a few cases the first symptoms is the development of blood clots in an unusual part of the circulatory system such as the liver. As the disease develops, the patients may have episodes of thromb osis or hemorrhage where the fact that thrombosis is the most frequent cause of death from polycythemia Vera. Other complications include a high concentration of uric acid in the blood which increases the risk of getting other diseases. About 10% of the patients eventually develop gout and the other 10% develop peptic ulcers. Based on MayoClinic (2012), one of the effects of polycyhemia Vera is causing the spleen to be greatly enlarged also known as splenomegaly as the spleen aids the body against infections and filter unwanted materials such as old or damaged blood cells. With the increased number of blood cells caused by polycythemia Vera, the spleen intends to work harder than normal which leads to spleen enlargement and the patients spleen may even be able to fill the entire left side of the abdomen as time goes on. Therefore, the patients might have the feeling of fullness or bloated in the upper left part of the abdomen. Where there is a problem, there will always be solutions to overcome it. According to the BodyandHealth.canada.com (1997), polycythemia Vera is treated with procedures, medicines, and some other treatments. A person with polycythemia Vera may need one or more treatments to manage this disease. The actual goals of treating this blood disease are to control the symptoms and reduce the risk of complications especially heart failure and stroke so in order to achieve the target, the treatments for polycythemia Vera reduce the number of erythrocytes and the level of hemoglobin in the blood which will make the thickness of the blood to be much closer to normal, thus reducing the chances of blood clots in the blood vessels. For this disease, the most recommended treatment is phlebotomy. Phlebotomy is a procedure that removes some blood from the body by inserting a needle into one of the veins and channels the blood into a sterile container via an airtight tube which is quite similar to the p rocess of blood donation. Through this treatment, the red blood cell count is reduced and this brings the thickness of the blood closer to normal. Typically, 1 unit of blood which is around 350ml is removed per week until the hematocrit level which is the measure of how much space red blood cells occupied in the blood falls back to normal and this process is normally carried out every few months. The next treatment involves medications, the doctors may prescribe certain medicines for example hydroxyurea and interferon-alpha that prevents the bone marrow from making way too many red blood cells. Hydroxyurea is a medicine generally used in treating cancer, it has the ability to reduce the number of red blood cells and platelets in the blood whereas interferon-alpha is a substance that our bodies usually produces to prompt our immune system to fight against overactive bone marrow cells. Moreover, radiation treatment is also available as it can help to suppress overactive bone marrow ce lls which prevent them from making red blood cells uncontrollably but this treatment is less recommended by doctors as the radiation treatment can increase the risk of leukaemia or other blood diseases. Another treatment is by taking aspirin as aspirin can relieve bone pain and the burning sensation in the hands and feet due to polycythemia Vera. In addition, aspirin also has the function to dilute blood so besides relieving pains it also thins the blood causing the blood to flow better in the blood vessels. However, taking aspirin can have side effects without the controlling the amount or dosage. For those who cannot resist the itching caused by polycythemia Vera, the doctor may also prescribe ultraviolet light treatment to relieve the itching. As preventions are better than cure, it is always a better choice not to rely too much on medications or drugs when solving problems related to health but try using other methods instead if possible. According to the NasionalHeartLungBloodinstitution (2011), people with polycythemia Vera should bath using cool water as it helps to reduce the irritation of the skin. Then, always remember to pat the body dry gently after bathing because vigorous rubbing with a towel can also irritate the skin as well. Lastly, one can also take starch baths by adding half a box of starch to a tub of lukewarm water because starch baths can actually help to soothe the skin. Besides taking trivial measures in daily activities, there are other ways to prevent or reduce the risk of one getting polycythemia Vera. First of all moderate physical activities such as walking and stretching is required to maintain a healthy heart rate and to improve blood flow in the body. By improving the blood flowing in the body , the risk of blood clots can be minimized. Following a healthy lifestyle can lower the risk of heart and lung disease, also will help to prevent one from developing secondary polycythemia. Sometimes, secondary polycythemia can be prevented by avoiding activities that will deprive our bodies of oxygen for long periods such as mountain climbing, smoking or other vigorous activities and sports. As a conclusion, polycythemia Vera is a chronic, and dangerous disease that can be very much fatal if not diagnosed and treated well. Although this disease has no cure, at least until today but the treatments provided will be able to help control the disease and its complications thus prolong more lives. However, it is wiser that we as the owner of our own health should bear most of the responsibilities rather than just relying on doctors and medicines when problems arise as an ounce of prevention is worth a pound of cure. Movements in Films | An overview Movements in Films | An overview Neoclassicism Neoclassicism (began after 1750) was a revival of Greek and Roman art; a direct reaction to the excessiveness of Baroque and Rococo styles. During the American and French Revolutions, the political atmosphere began to lean towards an Age of Reason and Enlightenment. With admiration for classical Roman and Greek art renewed after excavations of Herculaneum and Pompei, efforts for style to accompany philosophy caused an inevitable return to the classics. During this period, the subject matter often included a reverence for nature, tradition and the classics, moral values (such as nationalism and courage), along with a distrust for innovation. Early works of artists such as Jean August Dominique Ingres and especially Jacques-Louis David encompassed the thematic elements associated with Neoclassicism. Jacques-Louis Davids Oath of the Horatii can be considered as a turning point for the beginning of the neoclassic style. The painting possesses many qualities synonymous with neoclassicism. It is a tribute to Roman history, depicting three men with intense, dramatic and contrasted lighting, clarity of the characters forms/ gestures, and a deliberately simple composition. Davids Death of Marat is another example of a theatrical piece that combines a balanced composition and symbolism (martyrdom) with the moral undertone of the painting. Two other examples of Neoclassicist paintings are Napoleon I on his Imperial Throne and La Grande Odalis que. Romanticism Romanticism ( early-mid 19th century) was in reaction to Neoclassicism. Characteristics of Romanticist paintings include painterly brushstrokes, a clear display of emotion, nature, and diagonals. Some examples of this type of art includes Liberty Leading the People and Death of Sardanpalus by Eugà ¨ne Delacroix where his practiced use of expressive brushstrokes is made visible. Liberty Leading the People is an example of a romanticized symbol of France. Different social classes can be seen in French Romanticism, where the dead, dying, stronger, and strongest are specifically allocated throughout the piece. Other examples of Romanticist art includes The Raft of Medusa and Evening: Landscape with an Aquaduct by Thà ©odore Gà ©ricault. British Romanticism was more focused on using pure abstraction to help create expression. Examples include J.M. W. Turners Burning of Parliament and Rain, Steam and Speed The Great Western Railway. This type of use of ochre and white streaks was common, along with pastoral elements. John Constables The Hay Way and Dedham Vale are two other examples of British Romanticism. This type of art was easy to look at for the viewer. Realism Realism (mid 19th century) was created by a French group called the Barbizon School. Like the name implies a dedication to trying to capture the details through observation was an objective for the French Realists. Examples include Woman with a Pearl and Venise, La Piazzetta. Realists did not necessarily try to recreate what was directly in front of them, adjusting the situation to create an ideal piece was common and more practical. Other examples include Jean-Franà §ois Millets The Sower and The Gleaners. These types of works inspired the (post) impressionists that would see these exhibited paintings later on. Realism in landscapes is also seen in Courbets works, such as Plage de Normandie and Self-portrait (The Desperate Man) Impressionism Impressionism (1870s -1880s) was a term created from the first named Impressionist work, Claude Monets Impression, Sunrise. Characteristics of this type of painting includes the appreciation of art history, and an admiration upon light. Brush strokes are visible despite not being bold. Moments are captured, and time is a dimension that is fundamental in this type of art. Another example of a Monet that reflects Impressionisms characteristics well is Woman with a Parasol. Impressionism was a style that became highly developed, every brushstroke had its place, working with a highly selective palette. Edgar Degas New Orleans Cotton Exchange and The Dance Class are two famous examples of Impressionism. These paintings of ballet dancers became synonymous with the movement. Music in the Tuileries and The Luncheon on the Grass by Édouard Manet both further display this type of freeze-frame feeling. There is a certain serenity to this movement, and though the technique is variable, it ul timately results in a soft feel to the painting. The female figure was also often in the foreground of these pieces due to the political atmosphere, and the type of mood they helped establish within a piece. Post-Impressionism Post-Impressionism was a term coined by Roger Fry for one of Manets later exhibits. After no longer accepting the simple subject matter, and lack of compositional formatting in Impressionism, Post-Impressionist artists came up with their own ways to restore some more of the traditional compositional values into paintings. Georges Seurat used pointillism, a technique using dots of colour to allow them to blend into new colours through optical illusion, in his pieces such as Circus Sideshow and Le Chahut. Vincent Van Gogh used raw emotion and expressive brushstrokes in his pieces (Ex: Starry Night over the Rhone and Sunflowers, two of the most recognizable post-impressionist works) to recreate his own life and all the depressions that were contained within it. Other examples include Henri de Toulouse-Lautrecs At the Moulin Rouge: Two Women Waltzing and Quadrille at the Moulin Rouge. Late 19th Century Architecture Joseph Paxtons piece The Crystal Palace was a reaction to the Industrial Revolution, a piece that was the result of a movement away from traditional materials such as wood. Rather, a progression towards steel and new, more advanced materials was created. The Eiffel Tower (named after its engineer Gustave Eiffel) is another example of this type of architecture. An internation symbol for France, the tower is an engineering marvel, despite its intense criticism. Using purely steel for the structure of the body, it is an exploration of the new materials available during the era. Early 20th Century Architecture This type of architecture was a direct tie-in with Bauhaus. Artists such as Frank Lloyd Wright began exploring functional forms, and houses being living machines led to the creation of his works such as Falling Water, The Robie House and The Walter Fale House. The flat roofs and cantilever systems were brand new ideas in this type of art. Other examples include Le Corbusiers Centre Le Corbusier and Villa Savoye. Walter Gropius and Mies Van Der Rohe also explored the new possibilities created by mechanization and factories. (covered in Bauhaus) Suprematism Suprematism (which began in 1915) was a purely Russian art movement was devised by Kasimir Malevich as an era dedicated to geometric forms. Painting was reduced to ideas belonging to a supreme reality that embodied the essence of purity. This was a period that intersected cubo-futurism and (but came slightly before) Suprematism. Lyubov Popova was another important artist during this movement and a member of Malevichs Supremus group. His philosophy was that art should be reduced into a spiritual essence that exceeds the limits of religion and attains the supremacy of pure emotion. These paintings were minimal and done in a linear fashion. Malevichs Suprematist Composition: White on White is the ultimate example of Suprematism. After much experimentation with the tilting of a quadrilateral within a 4-dimensional frame and tampering with the relationship between art and science, the result was an incredibly pure painting using two shades of white. Another example would be Malevichs Black Square. Constructivism Constructivism (1919-1934), literally meaning to construct was a disciplinary artistic style that rose during the Russian Revolution. The new Communist order had decided to progress the ideas Analytic Cubism into the third dimension through sculpture. Contemporary, industrial materials such as glass, steel, wood, plastic were used in order to create engineering feats that were beyond art for arts sake. The movement was highly developed by Vladmir Tatlin, Naum Gabo, and Aleksander Rodchenko, the latter two who officially coined the term. According to Tatlin and his followers, these constructions were actually four-dimensional. Since they implied motion, they also implied time. The most recognizable piece of Constructivism was Tatlins attempt to create The Monument to the Third International. Meant to be constructed out of glass, iron and steel, it was hoped to have been a tower to supersede the Eiffel Tower in Paris. Even if the technology to create the monument had been available, there would most likely have been little to no structural practicality to it. In this type of utilitarian construction art, beauty is combined with some type of function or geometry: a twin helix being the main structure, glass four suspended forms (a cube, pyramid, a hemisphere, and a cylinder) all have practical uses, and the entire piece consists of futuristic paths to carry people through the structure with mechanical devices. Naum Gabo was colleagues and friends with Tatlin, Wassily Kandinsky, and Rodchenko. He began a new kind of plastic construction strung with nylon filament that comes very close to mathematical models. After looking for ties between art and science, the models he created in his Linear Construction series reflect upon modern physics that came after his time. Nylon threads are strung around a plexiglass base in an entirely mathematical arrangement. Contrary to many other constructivists, he partook in the movement in a purely spiritual sense. Gabo also had a strong interest in kinetic sculptures, which can be seen in his Revolving Torsion Fountain in London. With the main structure being made out of stainless steel, the contrastingly formless water is used as an integral moving element to complete the 4-dimensional composition. The jets pulsate at different levels, rotating and in particular rhythms. Selecting elements for specific purposes is a common trait of the mindset of a construc tivist. Dada Dadaism (1916-1922) was a direct reaction to the absurdity of World War I and the devastating amount of deaths it caused. This intellectual, anti-war movement ridiculed the disgusting parts of the world, such as the upper-class, rationale, and false nationalism and materialism. The name was selected randomly after flipping through a dictionary. This anti-art symbolized the opposite of everything that used to be considered aesthetically acceptable. Groups created in the name of Dada began forming, and the First German Dada Manifesto was published. Marcel Duchamp was a pioneer in this movement, beginning the use of readymades or found objects, and labelling them as art. His famous Fountain is nothing but a signed urinal, but captures the spirit of Dada. A worthless object has been signed to turn it into art, and is now something of value. Time, effort, and composition are no longer necessarily take into consideration to create art. L.H.O.O.Q. (Duchamp) was also another readymade piece of art, that is a mockery of traditional art. The name of the piece implies some kind of sexual joke based off the pun that comes from the French translation of Elle a chaud au cul, translating into There is a fire down below or She has a hot ass. This variant of the Mona Lisa was created many times, always with a moustache and beard in pencil upon the androgynous figures face. Taking part in the anti-art and nihilistic movement, Man Ray also began using readymades along with more conventional forms of media. His piece The Gift is a combination of an iron with rows of tacks glued to the bottom of. The object combines two ordinary objects to create a sadistic image and evokes a painful connection with the viewer. Another piece using a readymade by Ray is Indestructible Object. After photographing a picture of friend Lee Millers eye and placing it onto the moving pole of an analog metronome, Man Ray exhibited the piece naming it Object to Be Destroyed. In 1957, students destroyed his work, and after reconstructing, the piece was renamed Indestructible Object. Not only is the piece a part of Dada due to it being a readymade but the process and social criticism it received was expected from the movement. Acting against art, and raging for anti-art was a suitable response from viewers Surrealism Surrealism (began in the early 1920s) was a movement that succeeded Dada and contained many of the same artists. This cultural movement was highly influenced by the Freudian school of thought and psychiatry, dreams, fantasies and political motivations (Marxism/Communism/Anarchism) becoming a very intellectual reflection upon Parisian Nationalism, (sub)consciousness, and led to the creation of the Surrealist Manifesto. This movement to place across all media, such as painting, sculpture, photography, and film. The Surrealist Manifesto and the Second Manifesto of Surrealism were both written by Andre Breton. This poet was also a participant in the Dada movement, and at first praised automatic art and automatism of thoughts in art but later was more interested in narratives of dreams. The work of Salvador Dali is the quintessence of the period. His The Persistence of Memory is frighteningly realistic in terms of his technique like many of his other works, and uses symbols such as clocks, ants, and other unconscious creations. The reformation of a dream (in this case one of a paranoiac) on a canvas is the basis of most surrealist works. Another work that illustrates this Freudian idea of paranoia is Dalis Metamorphosis of Narcissus. The direct reflect of the staring Narcissus and the hand and egg is meant to recreate the feeling of paranoia when one mistakes one scenario for another. German Expressionism German Expressionism (1905-1925) was a period of raw, emotional art that took place between wars, during the recovery of World War I. The Treaty of Versailles had just been signed, and Germany was in large debt. This era was dedicated towards reflecting upon the difficult economy through not only paintings, but largely on film as well. This period was largely an influence on the Expressionism coming out of Germany at the same time. A cinematic example of a work of the era would be Metropolis by Fritz Lang. This science-fiction film was set in a relatable dystopia within a capitalist society where inter-class issues are the focus. Die Brucke was a group founded by four students specializing in architecture. These artists had no solid formal educations or school in art expect for some lessons. They worked cohesively and began a philosophical quest to bridge a bohemian life-style with a sense of imminent disaster. They were the driving force behind this movement. Sexual tension was a common theme in these pieces such as in Ernst Ludgwig Kitchners Self Portrait with Model and Georges Roualts Head of Christ. Both simplify shapes and use raw, simple colours to create very heavy, dense atmospheres around the pieces. Der Blaue Reiter was another group of artists led by Kandinsky and Franz Marc that wanted to approach their art more spiritually. These idealists sought to revive German art and eventually used woodcuts as their patriotic medium. Works from the group include Marcs The Tower of Blue Horses and Kandinskys Composition VII. This type of extreme and spiritual abstraction, and form simplification was part of the groups search for philosophical truth. Fauvism Fauvism (1904-1908), French for wild beasts, was a movement led by Henri Matisse and Andre Derain. Characteristics of the movement included bright areas of colour and flattening of form. The works were passionate and emotional with very painterly brush strokes and a focus on colour rather than realism. Matisses Woman with a Hat demonstrates this. Patches of colour surround the figure, and though a form is clear, there is definitely no focus upon trying to recreate what the artist saw directly. Rather, the colour scheme and interpretation of the colours at the moment are more important. This type of simplified colour/ figures is also seen with Matissess The Joy of Life. Andre Derain had worked with Matisse, and works such as Charing Cross Bridge exhibit the same type of bright, simplified colours but in a landscape setting. His Self-portrait in studio also shows this type of simplification, but with darker colours and more depth. This was a possible lead in to some of the ideas in the following movement. The boldness in colour and distortions during Fauvism is thought to have been from the influence of Van Gogh and Gaugins exhibited works. This was an incredibly modern movement in the 20th century. Cubism Analytic Cubism (1907-191) involves looking at the volume and space the structural unites from whicj to derive the faceted shapes of Analytic (or Facet) Cubism The facets are now so small and precise, more like prisms, and the canvas has the balance and refinement of a fully mature style There are high contrasts of texture and colour, monochromic palettes are common, and complex structures. Everything is broken down geometrically with sharp lines into cubistic forms. Synthetic Cubism (1912-1919) on the other hand was an alternative to Fauvism. Artists such as George Braque fell into this category, after beginning in Fauvism. This is also known as collage cubism. Form is flattened and there is a celebration of colour and the technique of collage. Some of Braques work in Analytic Cubism includes Violin, a piece that breaks apart a violin and is based off of a green hue, and The Mandolin, which focuses on different facets of a womans body practically disintegrating into sections. Picassos Still Life with Chair Caning and Guitar, Sheet Music, and Wine Glass are two examples of synthetic cubism. There are frames of reference, and things have been broken down in a way where it looks as if the final product was created through images being cut and paste on together. Bauhaus Bauhas was a school of thought that was founded by Walter Gropius in Germany and after development from previous concepts, buildings, and schools, the Bauhaus school building existed between 1919 and 1933 and had moved through three different cities due to Nazi pressure. Important components and influences of Bauhas wereInternational Style, functionalityin terms of (architectural) engineering, and geometric design principles. The Industrial Revolution, favtories, mass production and manufacturing were also a part of the movement. After the movement, many schools based their buildings and programs off the school. In general, the schools influence upon architecture, engineering, and redesign still impacts current lifestyles, presenting themselves everywhere in daily life (ex: the invention of tubular steel, flat-roofed buildings). The original director and master of Bauhaus, Gropius was largely responsible for the F 51 Armchair and Sofa. Other creations in modern dà ©cor by him include the D 51 and F 51-2. One of the later directors Ludwig Mies van der Rohe designed the Farnsworth house, 960-880 Lake Shore Drive Apartments, and Seagram building. All these buildings reflect upon his mission to advance architecture with the leaps in technology and industry, combining rationalism with spirituality. Universally known, his Barcelona Chair and Ottoman is a modernistic icon that involves a twist upon Curule chairs and was manufactured/ targeted towards the common man market. Hannes Meyer was the second director of Bauhaus and was the first to help the school earn profit. He brought significant commission for the school, including creating building for the Gederal School of the German Trade Unions in Bernau and five apartment buildings in Dessau. American Abstract Expressionism Abstract expressionism (1940s-1950s) was the first entirely American-caused movement in direct reaction to World War II. Paint was put onto a surface to create pure art that had no narrative. Rather the pieces depended purely on line, form, surface, and the way paint acts. Harold Rosenberg described Pollock and other Abstract Expressionist canvases as an arena in which to act. What was to go on the canvas was not a picture but an event. Many paintings were described as action paintings, in where the process and layering of the paint could be considered more interesting and important than the final product and composition itself. Mark Rothko would use chunks of paint to create his pieces, to create multiforms. This was his key style and can be seen in No. 3/ No. 13. The canvas consists of only 6 colours in blocks. Another example is his painting No. 10. In contrast, Jackson Pollock often threw paint onto the surface, allowing it to do what paint does. His paintings No. 5, and Lavender are examples of his paint-throwing and recognizable dripping techniques. Other examples of Abstract Expressionist works include Lee Krasners Celebration and Little Image paintings, along with Barnett Newmans Onement 1and Whos Afraid of Red, Yellow, and Blue? Pop Art Pop art (began in mid 1950s) was based in Britain and the United States. Pop art was a diurect reaction to the high intellectualism of Abstract Expressionism, often focusing upon ordinary objects and regular daily commodities. Subject matter often included objects such as soup cans, boxes, comic boos, photos, etc. Pop culture and the Hollywood scene was a major influence upon the art during this age of mechanical reproduction. Richard Hamiltons collage Just What Is it that Makes Todays Homes So Different, So Appealing? is an iconic piece created from images from American magazines and is a reflection upon the economy, homes, and lifestyle of the time. Andy Warhols Campbells Soup I and series used the American food staple as the subject to avoid competing with Roy Lichensteins comic strip pieces and his potential as a consumer, being solely dedicated to the brand and product. Lictensteins infamous Whaam!contains an image of an American plane destroying an enemy jet. This comic-strip type of art was a reflection on the American lifestyle and the popularity of comic books during the age and the piece was based off an actual comic book panel. The piece tries not to develop a purposeful connection with the audience, allowing viewers to develop their own thoughts and interpretation of the image and caption. Claes Oldenburg also used this idea of consumer products, and often create soft sculptures of mundane obje cts. Lipstick (Ascending) on Caterpillar Tracks involved an oversized lipstick that would constantly deflate itself unless pumped by a viewer. Other pieces from the era include Oldenburgs Soft Bathtub (Model), Lichtensteins Drowning Girl, Hamiltons Interior and Warhols Brillo Box. Earth Art During Earth Art (late 1960s into early 1970s), artists began a movement against the restrictive qualities of galleries and traditional exhibitions. A desire for an open canvas led to the use of nature as a medium. In reaction to consumerism and the vast commercialization of art, the reaction of these artists was to create something impossible to purchase by using only natural materials, usually in an environment that could not be sold. As well, the temporary nature of most of these works would factor into how unfeasible it would be to attempt to purchase these works. Usually, these works can only exist through documentation as they are otherwise eradicated by time. Leading artist Robert Smithson created the Broken Circle and Spiral Jetty, two famous works that emerged during the period. Both pieces are protected, but nevertheless people still try to obtain parts of these works. Richard Long creates his pieces through walking upon paths entirely drawn from him. A Circle in Alaska Be ring Straight Driftwood on the Arctic Circle and A Line Made By Walking are two works both created through the pure interaction of his body and his earth. They will only last until nature takes its course, a trademark of Earth art. Christo and his wife Jean Claude focused their works upon the form that the world takes up, and wanted people to see things in a new perspective. Through many wrapped pieces, they considered themselves to be bringing unseen beauty to certain environemtns. The Running Fence and the wrapping of Point Neuf Bridge are some incredibly recognizable pieces. Both are reflections upon the form of nature. Minimalism Minimalism (late 1960s-early 1970s) involved the belief that there should be no agenda for a piece but the piece should be centred on itself. This type of art implies true aesthetic value. Often the works are precise, mechanical, and ready to be manufactured in a factory setting. The pieces are repetitive with no symbolism and are modular. Contrasting colours, sharp outlines, and a basis on geometric forms and the frame of reference were also components of this style. This was also applicable in the sculptural aspects of the style. Materials for this type of sculpture was usually industrial, ex: fiberglass, plastics/ other synthetics, metals. Donald Judds pieces are often untitled works that are simple and based purely on mathematics and geometry. This was also the same with Robert Morris. Richard Serra has a piece similar to one of Judds untitled works where a sculpture contains contains circles within circles at different tilts and heights. These were installations, however Solomon LeWitt focused more upon two dimensional pieces like Isometric Projection, Untitled (lithograph), and Tower. Serras The Matter Of Time and Fulcrum are sculptures based purely on untreated metals and steels. Performance Art Current Performance Art began in the beginning of the first half of the 20th century. The movement was dedicated towards the history of theatre. However, by the 1970s, Performance Art was usually concentrated and combined efforts on Happenings and Conceptual Art with installations. Shock value, (self-) mutilation, explicit sexuality, grotesque and unconventional humour. Audience interaction and breaking the fourth wall was also quite common. Laurie Anderson is a musician who experiments not only in sound through playing the violin and piano, but with her performances as well. She created the tape-bow violin that is still used as an experimental type of instrument by artists and musicians today. In the 1970s she performed/ recorded a violin piece while performing until the block of ice of which she stood on with ice skates completely melted away. Vito Acconci created an installation named Seedbed in which he was located beneath a ramp at the Sonnabend Gallery, where he masturbated and created a speaker system to allow his speakers here his voice and thoughts. Joseph Beuys had some notable performances, particularly when he became involved with Fluxus temporarily. His performance, How to Explain Pictures to a Dead Hare involved Beuys speaking into the ear of a dead hare he held in his arms, while his boot had an attached piece of iron, and his face was covered in honey and gold leaf. All these objects had a symbolic meanin g and there was an intended intellectual message for his audience. This Fluxus movement involiving multi-media flow also produced member Yoko Ono. Her performance Cut Piece (which can also be considered a happening) involved the audience participating through cutting her clothing off until she was naked. This allowed Ono to communicate her own feelings towards her audience through body and performance, rather than conventional mediums.

Preventing Child Abuse Essay -- Violence Against Children

Child abuse is a phenomenon in today’s society. Many people have been victims and although it has been taken into consideration, more surveillance should be taking place. There are three types of abuse that ruin the life of a child: physical, emotional, and sexual. However, focusing on domestic violence, a child will be affected by physical and emotional abuse. The problem is that some parents may not even consider how it affects their child in public places. When a child has been abused, how long does it affect him or her into adulthood? Though there are different ways to discipline, a parent can choose from a variety of rewards to reinforce good behavior; furthermore, a trusted committee should organize ongoing parenting classes to help parents to control their temper. What are the other consequences of abuse? Parents who abuse their kids were abused and had a poor upbringing. Nowadays with technology and researches found, they could help change and also teach their kids to avoid the same mistakes when they grow up. As the child grows, parents can set limits instead of violence. Fact is that when kids behave out of the normal, it is not to make parents angry but because they are in need of attention. We all know that parents’ the first reaction is to lose it, so instead of punching, parents can try time outs until the child comprehends why he or she is being punished. It is also a matter of good training in junior high. Kids are always trying to act bigger than their shoe size. A method that could help both the parents and the teen is the motivated reward. By doing this, the child makes better decision, because if the parent knows what motivates a child, that could help the child behave differently in order to get what he or sh... ...uld have done about it. Children who have a second shot at a loving upbringing have the capacity to change the world where they will know how to say â€Å"no† to abuse. They will also be able to talk to their own children about abusive moments and what they should do reacting to that moment. They will know that abusers could be anyone and that is important to tell a trusted friend if someone abuses them.

Chapter 24 Rita Skeeter’s Scoop

Everybody got up late on Boxing Day. The Gryffindor common room was much quieter than it had been lately, many yawns punctuating the lazy conversations. Hermione's hair was bushy again; she confessed to Harry that she had used liberal amounts of Sleekeazy's Hair Potion on it for the ball, â€Å"but it's way too much bother to do every day,† she said matter-of-factly, scratching a purring Crookshanks behind the ears. Ron and Hermione seemed to have reached an unspoken agreement not to discuss their argument. They were being quite friendly to each other, though oddly formal. Ron and Harry wasted no time in telling Hermione about the conversation they had overheard between Madame Maxime and Hagrid, but Hermione didn't seem to find the news that Hagrid was a half-giant nearly as shocking as Ron did. â€Å"Well, I thought he must be,† she said, shrugging. â€Å"I knew he couldn't be pure giant because they're about twenty feet tall. But honestly, all this hysteria about giants. They can't all be horrible†¦.It's the same sort of prejudice that people have toward werewolves†¦.It's just bigotry, isn't it?† Ron looked as though he would have liked to reply scathingly, but perhaps he didn't want another row, because he contented himself with shaking his head disbelievingly while Hermione wasn't looking. It was time now to think of the homework they had neglected during the first week of the holidays. Everybody seemed to be feeling rather flat now that Christmas was over – everybody except Harry, that is, who was starting (once again) to feel slightly nervous. The trouble was that February the twenty-fourth looked a lot closer from this side of Christmas, and he still hadn't done anything about working out the clue inside the golden egg. He therefore started taking the egg out of his trunk every time he went up to the dormitory, opening it, and listening intently, hoping that this time it would make some sense. He strained to think what the sound reminded him of, apart from thirty musical saws, but he had never heard anything else like it. He closed the egg, shook it vigorously, and opened it again to see if the sound had changed, but it hadn't. He tried asking the egg questions, shouting over all the wailing, but nothing happened. He even threw the egg across the room – though he hadn't really expected that to help. Harry had not forgotten the hint that Cedric had given him, but his less-than-friendly feelings toward Cedric just now meant that he was keen not to take his help if he could avoid it. In any case, it seemed to him that if Cedric had really wanted to give Harry a hand, he would have been a lot more explicit. He, Harry, had told Cedric exactly what was coming in the first task – and Cedric's idea of a fair exchange had been to tell Harry to take a bath. Well, he didn't need that sort of rubbishy help – not from someone who kept walking down corridors hand in hand with Cho, anyway. And so the first day of the new term arrived, and Harry set off to lessons, weighed down with books, parchment, and quills as usual, but also with the lurking worry of the egg heavy in his stomach, as though he were carrying that around with him too. Snow was still thick upon the grounds, and the greenhouse windows were covered in condensation so thick that they couldn't see out of them in Herbology. Nobody was looking forward to Care of Magical Creatures much in this weather, though as Ron said, the skrewts would probably warm them up nicely, either by chasing them, or blasting off so forcefully that Hagrid's cabin would catch fire. When they arrived at Hagrid ‘s cabin, however, they found an elderly witch with closely cropped gray hair and a very prominent chin standing before his front door. â€Å"Hurry up, now, the bell rang five minutes ago,† she barked at them as they struggled toward her through the snow. â€Å"Who're you?† said Ron, staring at her. â€Å"Where's Hagrid?† â€Å"My name is Professor Grubbly-Plank,† she said briskly. â€Å"I am your temporary Care of Magical Creatures teacher.† â€Å"Where's Hagrid?† Harry repeated loudly. â€Å"He is indisposed,† said Professor Grubbly-Plank shortly. Soft and unpleasant laughter reached Harry's ears. He turned; Draco Malfoy and the rest of the Slytherins were joining the class. All of them looked gleeful, and none of them looked surprised to see Professor Grubbly-Plank. â€Å"This way, please,† said Professor Grubbly-Plank, and she strode off around the paddock where the Beauxbatons horses were shivering. Harry, Ron, and Hermione followed her, looking back over their shoulders at Hagrid's cabin. All the curtains were closed. Was Hagrid in there, alone and ill? â€Å"What's wrong with Hagrid?† Harry said, hurrying to catch up with Professor Grubbly-Plank. â€Å"Never you mind,† she said as though she thought he was being nosy. â€Å"I do mind, though,† said Harry hotly. â€Å"What's up with him?† Professor Grubbly-Plank acted as though she couldn't hear him. She led them past the paddock where the huge Beauxbatons horses were standing, huddled against the cold, and toward a tree on the edge of the forest, where a large and beautiful unicorn was tethered. Many of the girls â€Å"ooooohed!† at the sight of the unicorn. â€Å"Oh it's so beautiful!† whispered Lavender Brown. â€Å"How did she get it? They're supposed to be really hard to catch!† The unicorn was so brightly white it made the snow all around look gray. It was pawing the ground nervously with its golden hooves and throwing back its horned head. â€Å"Boys keep back!† barked Professor Grubbly-Plank, throwing out an arm and catching Harry hard in the chest. â€Å"They prefer the woman's touch, unicorns. Girls to the front, and approach with care, come on, easy does it†¦.† She and the girls walked slowly forward toward the unicorn, leaving the boys standing near the paddock fence, watching. The moment Professor Grubbly-Plank was out of earshot. Harry turned to Ron. â€Å"What d'you reckons wrong with him? You don't think a skrewt -?† â€Å"Oh he hasn't been attacked, Potter, if that's what you're thinking,† said Malfoy softly. â€Å"No, he's just too ashamed to show his big, ugly face.† â€Å"What d'you mean?† said Harry sharply. Malfoy put his hand inside the pocket of his robes and pulled out a folded page of newsprint. â€Å"There you go,† he said. â€Å"Hate to break it to you. Potter†¦.† He smirked as Harry snatched the page, unfolded it, and read it, with Ron, Seamus, Dean, and Neville looking over his shoulder. It was an article topped with a picture of Hagrid looking extremely shifty. DUMBLEDORE'S GIANT MISTAKE Albus Dumbledore, eccentric Headmaster of Hogwarts School of Witchcraft and Wizardry, has never been afraid to make controversial staff appointments, writes Rita Skeeter, Special Correspondent. In September of this year, he hired Alastor â€Å"Mad-Eye† Moody, the notoriously jinx-happy ex-Auror, to teach Defense Against the Dark Arts, a decision that caused many raised eyebrows at the Ministry of Magic, given Moody's well-known habit of attacking anybody who makes a sudden movement in his presence. Mad-Eye Moody, however, looks responsible and kindly when set beside the part-human Dumbledore employs to teach Care of Magical Creatures. Rubeus Hagrid, who admits to being expelled from Hogwarts in his third year, has enjoyed the position of gamekeeper at the school ever since, a job secured for him by Dumbledore. Last year, however, Hagrid used his mysterious influence over the headmaster to secure the additional post of Care of Magical Creatures teache r, over the heads of many better-qualified candidates. An alarmingly large and ferocious-looking man, Hagrid has been using his newfound authority to terrify the students in his care with a succession of horrific creatures. While Dumbledore turns a blind eye, Hagrid has maimed several pupils during a series of lessons that many admit to being â€Å"very frightening.† ‘I was attacked by a hippogriff, and my friend Vincent Crabbe got a bad bite off a flobberworm,† says Draco Malfoy, a fourth-year student. â€Å"We all hate Hagrid, but we're just too scared to say anything.† Hagrid has no intention of ceasing his campaign of intimidation, however. In conversation with a Daily Prophet reporter last month, he admitted breeding creatures he has dubbed â€Å"Blast-Ended Skrewts,† highly dangerous crosses between manti-cores and fire-crabs. The creation of new breeds of magical creature is, of course, an activity usually closely observed by the Department fo r the Regulation and Control of Magical Creatures. Hagrid, however, considers himself to be above such petty restrictions. â€Å"I was just having some fun,† he says, before hastily changing the subject. As if this were not enough, the Daily Prophet has now unearthed evidence that Hagrid is not – as he has always pretended – a pure-blood wizard. He is not, in fact, even pure human. His mother, we can exclusively reveal, is none other than the giantess Fridwulfa, whose whereabouts are currently unknown. Bloodthirsty and brutal, the giants brought themselves to the point of extinction by warring amongst themselves during the last century. The handful that remained joined the ranks of He-Who-Must-Not-Be-Named, and were responsible for some of the worst mass Muggle killings of his reign of terror. While many of the giants who served He-Who-Must-Not-Be-Named were killed by Aurors working against the Dark Side, Fridwulfa was not among them. It is possible she escaped to one of the giant communities still existing in foreign mountain ranges. If his antics during Care of Magical Creatures lessons are any guide, however, Frid-wulfa's son appears to have inherited her brutal nature. In a bizarre twist, Hagrid is reputed to have developed a close friendship with the boy who brought around You-Know-Who's fall from power – thereby driving Hagrid's own mother, like the rest of You-Know-Who's supporters, into hiding. Perhaps Harry Potter is unaware of the unpleasant truth about his large friend – but Albus Dumbledore surely has a duty to ensure that Harry Potter, along with his fellow students, is warned about the dangers of associating with part-giants. Harry finished reading and looked up at Ron, whose mouth was hanging open. â€Å"How did she find out?† he whispered. But that wasn't what was bothering Harry. â€Å"What d'you mean, ‘we all hate Hagrid'?† Harry spat at Malfoy. â€Å"What's this rubbish about him† – he pointed at Crabbe – â€Å"getting a bad bite off a flobberworm? They haven't even got teeth!† Crabbe was sniggering, apparently very pleased with himself. â€Å"Well, I think this should put an end to the oaf's teaching career,† said Malfoy, his eyes glinting. â€Å"Half-giant†¦and there was me thinking he'd just swallowed a bottle of Skele-Gro when he was young†¦.None of the mummies and daddies are going to like this at all†¦.They'll be worried he'll eat their kids, ha, ha†¦.† â€Å"You -â€Å" â€Å"Are you paying attention over there?† Professor Grubbly-Planks voice carried over to the boys; the girls were all clustered around the unicorn now, stroking it. Harry was so angry that the Daily Prophet article shook in his hands as he turned to stare unseeingly at the unicorn, whose many magical properties Professor Grubbly-Plank was now enumerating in a loud voice, so that the boys could hear too. â€Å"I hope she stays, that woman!† said Parvati Patil when the lesson had ended and they were all heading back to the castle for lunch. â€Å"That's more what I thought Care of Magical Creatures would be like†¦proper creatures like unicorns, not monsters†¦.† â€Å"What about Hagrid?† Harry said angrily as they went up the steps. â€Å"What about him?† said Parvati in a hard voice. â€Å"He can still be gamekeeper, can't he?† Parvati had been very cool toward Harry since the ball. He supposed that he ought to have paid her a bit more attention, but she seemed to have had a good time all the same. She was certainly telling anybody who would listen that she had made arrangements to meet the boy from Beauxbatons in Hogsmeade on the next weekend trip. â€Å"That was a really good lesson,† said Hermione as they entered the Great Hall. â€Å"I didn't know half the things Professor Grubbly-Plank told us about uni -â€Å" â€Å"Look at this!† Harry snarled, and he shoved the Daily Prophet article under Hermione's nose. Hermione's mouth fell open as she read. Her reaction was exactly the same as Ron's. â€Å"How did that horrible Skeeter woman find out? You don't think Hagrid told her?† â€Å"No,† said Harry, leading the way over to the Gryffindor table and throwing himself into a chair, furious. â€Å"He never even told us, did he? I reckon she was so mad he wouldn't give her loads of horrible stuff about me, she went ferreting around to get him back.† â€Å"Maybe she heard him telling Madame Maxime at the ball,† said Hermione quietly. â€Å"We'd have seen her in the garden!† said Ron. â€Å"Anyway, she's not supposed to come into school anymore, Hagrid said Dumbledore banned her†¦.† â€Å"Maybe she's got an Invisibility Cloak,† said Harry, ladling chicken casserole onto his plate and splashing it everywhere in his anger. â€Å"Sort of thing she'd do, isn't it, hide in bushes listening to people.† â€Å"Like you and Ron did, you mean,† said Hermione. â€Å"We weren't trying to hear him!† said Ron indignantly. â€Å"We didn't have any choice! The stupid prat, talking about his giantess mother where anyone could have heard him!† â€Å"We've got to go and see him,† said Harry. â€Å"This evening, after Divination. Tell him we want him back†¦you do want him back?† he shot at Hermione. â€Å"I – well, I'm not going to pretend it didn't make a nice change, having a proper Care of Magical Creatures lesson for once – but I do want Hagrid back, of course I do!† Hermione added hastily, quailing under Harry's furious stare. So that evening after dinner, the three of them left the castle once more and went down through the frozen grounds to Hagrid's cabin. They knocked, and Fang's booming barks answered. â€Å"Hagrid, it's us!† Harry shouted, pounding on the door. â€Å"Open up!† Hagrid didn't answer. They could hear Fang scratching at the door, whining, but it didn't open. They hammered on it for ten more minutes; Ron even went and banged on one of the windows, but there was no response. â€Å"What's he avoiding us for?† Hermione said when they had finally given up and were walking back to the school. â€Å"He surely doesn't think we'd care about him being half-giant?† But it seemed that Hagrid did care. They didn't see a sign of him all week. He didn't appear at the staff table at mealtimes, they didn't see him going about his gamekeeper duties on the grounds, and Professor Grubbly-Plank continued to take the Care of Magical Creatures classes. Malfoy was gloating at every possible opportunity. â€Å"Missing your half-breed pal?† he kept whispering to Harry whenever there was a teacher around, so that he was safe from Harry's retaliation. â€Å"Missing the elephant-man?† There was a Hogsmeade visit halfway through January. Hermione was very surprised that Harry was going to go. â€Å"I just thought you'd want to take advantage of the common room being quiet,† she said. â€Å"Really get to work on that egg.† â€Å"Oh I – I reckon I've got a pretty good idea what it's about now,† Harry lied. â€Å"Have you really?† said Hermione, looking impressed. â€Å"Well done!† Harry's insides gave a guilty squirm, but he ignored them. He still had five weeks to work out that egg clue, after all, and that was ages†¦whereas if he went into Hogsmeade, he might run into Hagrid, and get a chance to persuade him to come back. He, Ron, and Hermione left the castle together on Saturday and set off through the cold, wet grounds toward the gates. As they passed the Durmstrang ship moored in the lake, they saw Viktor Krum emerge onto the deck, dressed in nothing but swimming trunks. He was very skinny indeed, but apparently a lot tougher than he looked, because he climbed up onto the side of the ship, stretched out his arms, and dived, right into the lake. â€Å"He's mad!† said Harry, staring at Krum's dark head as it bobbed out into the middle of the lake. â€Å"It must be freezing, it's January!† â€Å"It's a lot colder where he comes from,† said Hermione. â€Å"I suppose it feels quite warm to him.† â€Å"Yeah, but there's still the giant squid,† said Ron. He didn't sound anxious – if anything, he sounded hopeful. Hermione noticed his tone of voice and frowned. â€Å"He's really nice, you know,† she said. â€Å"He's not at all like you'd think, coming from Durmstrang. He likes it much better here, he told me.† Ron said nothing. He hadn't mentioned Viktor Krum since the ball, but Harry had found a miniature arm under his bed on Boxing Day, which had looked very much as though it had been snapped off a small model figure wearing Bulgarian Quidditch robes. Harry kept his eyes skinned for a sign of Hagrid all the way down the slushy High Street, and suggested a visit to the Three Broomsticks once he had ascertained that Hagrid was not in any of the shops. The pub was as crowded as ever, but one quick look around at all the tables told Harry that Hagrid wasn't there. Heart sinking, he went up to the bar with Ron and Hermione, ordered three butterbeers from Madam Rosmerta, and thought gloomily that he might just as well have stayed behind and listened to the egg wailing after all. â€Å"Doesn't he ever go into the office?† Hermione whispered suddenly. â€Å"Look!† She pointed into the mirror behind the bar, and Harry saw Ludo Bagman reflected there, sitting in a shadowy corner with a bunch of goblins. Bagman was talking very fast in a low voice to the goblins, all of whom had their arms crossed and were looking rather menacing. It was indeed odd. Harry thought, that Bagman was here at the Three Broomsticks on a weekend when there was no Triwizard event, and therefore no judging to be done. He watched Bagman in the mirror. He was looking strained again, quite as strained as he had that night in the forest before the Dark Mark had appeared. But just then Bagman glanced over at the bar, saw Harry, and stood up. â€Å"In a moment, in a moment!† Harry heard him say brusquely to the goblins, and Bagman hurried through the pub toward Harry, his boyish grin back in place. â€Å"Harry!† he said. â€Å"How are you? Been hoping to run into you! Everything going all right?† â€Å"Fine, thanks,† said Harry. â€Å"Wonder if I could have a quick, private word, Harry?† said Bagman eagerly. â€Å"You couldn't give us a moment, you two, could you?† â€Å"Er – okay,† said Ron, and he and Hermione went off to find a table. Bagman led Harry along the bar to the end furthest from Madam Rosmerta. â€Å"Well, I just thought I'd congratulate you again on your splendid performance against that Horntail, Harry,† said Bagman. â€Å"Really superb.† â€Å"Thanks,† said Harry, but he knew this couldn't be all that Bagman wanted to say, because he could have congratulated Harry in front of Ron and Hermione. Bagman didn't seem in any particular rush to spill the beans, though. Harry saw him glance into the mirror over the bar at the goblins, who were all watching him and Harry in silence through their dark, slanting eyes. â€Å"Absolute nightmare,† said Bagman to Harry in an undertone, noticing Harry watching the goblins too. â€Å"Their English isn't too good†¦it's like being back with all the Bulgarians at the Quidditch World Cup†¦but at least they used sign language another human could recognize. This lot keep gabbling in Gobblede-gook†¦and I only know one word of Gobbledegook. Bladvak. It means ‘pickax.' I don't like to use it in case they think I'm threatening them.† He gave a short, booming laugh. â€Å"What do they want?† Harry said, noticing how the goblins were still watching Bagman very closely. â€Å"Er – well†¦Ã¢â‚¬  said Bagman, looking suddenly nervous. â€Å"They†¦er†¦they're looking for Barty Crouch.† â€Å"Why are they looking for him here?† said Harry. â€Å"He's at the Ministry in London, isn't he?† â€Å"Er†¦as a matter of fact, I've no idea where he is,† said Bagman. â€Å"He's sort of†¦stopped coming to work. Been absent for a couple of weeks now. Young Percy, his assistant, says he's ill. Apparently he's just been sending instructions in by owl. But would you mind not mentioning that to anyone. Harry? Because Rita Skeeter's still poking around everywhere she can, and I'm willing to bet she'd work up Bartys illness into something sinister. Probably say he's gone missing like Bertha Jorkins.† â€Å"Have you heard anything about Bertha Jorkins?† Harry asked. â€Å"No,† said Bagman, looking strained again. â€Å"I've got people looking, of course†¦Ã¢â‚¬  (About time, thought Harry) â€Å"and it's all very strange. She definitely arrived in Albania, because she met her second cousin there. And then she left the cousin's house to go south and see an aunt†¦and she seems to have vanished without trace en route. Blowed if I can see where she's got to†¦she doesn't seem the type to elope, for instance†¦but still†¦.What are we doing, talking about goblins and Bertha Jorkins? I really wanted to ask you† – he lowered his voice – â€Å"how are you getting on with your golden egg?† â€Å"Er†¦not bad,† Harry said untruthfully. Bagman seemed to know he wasn't being honest. â€Å"Listen, Harry,† he said (still in a very low voice), â€Å"I feel very bad about all this†¦you were thrown into this tournament, you didn't volunteer for it†¦and if†¦Ã¢â‚¬  (his voice was so quiet now, Harry had to lean closer to listen) â€Å"if I can help at all†¦a prod in the right direction†¦I've taken a liking to you†¦the way you got past that dragon!†¦well, just say the word.† Harry stared up into Bagman's round, rosy face and his wide, baby-blue eyes. â€Å"We're supposed to work out the clues alone, aren't we?† he said, careful to keep his voice casual and not sound as though he was accusing the head of the Department of Magical Games and Sports of breaking the rules. â€Å"Well†¦well, yes,† said Bagman impatiently, â€Å"but – come on. Harry – we all want a Hogwarts victory, don't we?† â€Å"Have you offered Cedric help?† Harry said. The smallest of frowns creased Bagman's smooth face. â€Å"No, I haven't,† he said. â€Å"I – well, like I say, I've taken a liking to you. Just thought I'd offer†¦Ã¢â‚¬  â€Å"Well, thanks,† said Harry, â€Å"but I think I'm nearly there with the egg†¦couple more days should crack it.† He wasn't entirely sure why he was refusing Bagman's help, except that Bagman was almost a stranger to him, and accepting his assistance would feel somehow much more like cheating than asking advice from Ron, Hermione, or Sirius. Bagman looked almost affronted, but couldn't say much more as Fred and George turned up at that point. â€Å"Hello, Mr. Bagman,† said Fred brightly. â€Å"Can we buy you a drink?† â€Å"Er†¦no,† said Bagman, with a last disappointed glance at Harry, â€Å"no, thank you, boys†¦Ã¢â‚¬  Fred and George looked quite as disappointed as Bagman, who was surveying Harry as though he had let him down badly. â€Å"Well, I must dash,† he said. â€Å"Nice seeing you all. Good luck, Harry.† He hurried out of the pub. The goblins all slid off their chairs and exited after him. Harry went to rejoin Ron and Hermione. â€Å"What did he want?† Ron said, the moment Harry had sat down. â€Å"He offered to help me with the golden egg,† said Harry. â€Å"He shouldn't be doing that!† said Hermione, looking very shocked. â€Å"He's one of the judges! And anyway, you've already worked it out – haven't you?† â€Å"Er†¦nearly,† said Harry. â€Å"Well, I don't think Dumbledore would like it if he knew Bagman was trying to persuade you to cheat!† said Hermione, still looking deeply disapproving. â€Å"I hope he's trying to help Cedric as much!† â€Å"He's not, I asked,† said Harry. â€Å"Who cares if Diggory's getting help?† said Ron. Harry privately agreed. â€Å"Those goblins didn't look very friendly,† said Hermione, sipping her butterbeer. â€Å"What were they doing here?† â€Å"Looking for Crouch, according to Bagman,† said Harry. â€Å"He's still ill. Hasn't been into work.† â€Å"Maybe Percy's poisoning him,† said Ron. â€Å"Probably thinks if Crouch snuffs it he'll be made head of the Department of International Magical Cooperation.† Hermione gave Ron a don't-joke-about-things-like-that look, and said, â€Å"Funny, goblins looking for Mr. Crouch†¦.They'd normally deal with the Department for the Regulation and Control of Magical Creatures.† â€Å"Crouch can speak loads of different languages, though,† said Harry. â€Å"Maybe they need an interpreter.† â€Å"Worrying about poor ‘ickle goblins, now, are you?† Ron asked Hermione. â€Å"Thinking of starting up S.P.U.G. or something? Society for the Protection of Ugly Goblins?† â€Å"Ha, ha, ha,† said Hermione sarcastically. â€Å"Goblins don't need protection. Haven't you been listening to what Professor Binns has been telling us about goblin rebellions?† â€Å"No,† said Harry and Ron together. â€Å"Well, the're quite capable of dealing with wizards,† said Hermione, taking another sip of butterbeer. â€Å"They're very clever. They're not like house-elves, who never stick up for themselves.† â€Å"Uh-oh,† said Ron, staring at the door. Rita Skeeter had just entered. She was wearing banana-yellow robes today; her long nails were painted shocking pink, and she was accompanied by her paunchy photographer. She bought drinks, and she and the photographer made their way through the crowds to a table nearby. Harry, Ron, and Hermione glaring at her as she approached. She was talking fast and looking very satisfied about something. â€Å"†¦didn't seem very keen to talk to us, did he, Bozo? Now, why would that be, do you think? And what's he doing with a pack of goblins in tow anyway? Showing them the sights†¦what nonsense†¦he was always a bad liar. Reckon something's up? Think we should do a bit of digging? ‘Disgraced Ex-Head of Magical Games and Sports, Ludo Bagman†¦' Snappy start to a sentence, Bozo – we just need to find a story to fit it -â€Å" â€Å"Trying to ruin someone else's life?† said Harry loudly. A few people looked around. Rita Skeeter's eyes widened behind her jeweled spectacles as she saw who had spoken. â€Å"Harry!† she said, beaming. â€Å"How lovely! Why don't you come and join-?† â€Å"I wouldn't come near you with a ten-foot broomstick,† said Harry furiously. â€Å"What did you do that to Hagrid for, eh?† Rita Skeeter raised her heavily penciled eyebrows. â€Å"Our readers have a right to the truth, Harry. I am merely doing my-â€Å" â€Å"Who cares if he's half-giant?† Harry shouted. â€Å"There's nothing wrong with him!† The whole pub had gone very quiet. Madam Rosmerta was staring over from behind the bar, apparently oblivious to the fact that the flagon she was filling with mead was overflowing. Rita Skeeter's smile flickered very slightly, but she hitched it back almost at once; she snapped open her crocodile-skin handbag, pulled out her Quick-Quotes Quill, and said, â€Å"How about giving me an interview about the Hagrid you know. Harry? The man behind the muscles? Your unlikely friendship and the reasons behind it. Would you call him a father substitute?† Hermione stood up very abruptly, her butterbeer clutched in her hand as though it were a grenade. â€Å"You horrible woman,† she said, through gritted teeth, â€Å"you don't care, do you, anything for a story, and anyone will do, wont they? Even Ludo Bagman -â€Å" â€Å"Sit down, you silly little girl, and don't talk about things you don't understand,† said Rita Skeeter coldly, her eyes hardening as they fell on Hermione. â€Å"I know things about Ludo Bagman that would make your hair curl†¦not that it needs it -† she added, eyeing Hermione's bushy hair. â€Å"Let's go,† said Hermione, â€Å"c'mon. Harry – Ron†¦Ã¢â‚¬  They left; many people were staring at them as they went. Harry glanced back as they reached the door. Rita Skeeter's Quick-Quotes Quill was out; it was zooming backward and forward over a piece of parchment on the table. â€Å"She'll be after you next, Hermione,† said Ron in a low and worried voice as they walked quickly back up the street. â€Å"Let her try!† said Hermione defiantly; she was shaking with rage. â€Å"I'll show her! Silly little girl, am I? Oh, I'll get her back for this. First Harry, then Hagrid†¦Ã¢â‚¬  â€Å"You don't want to go upsetting Rita Skeeter,† said Ron nervously. â€Å"I'm serious, Hermione, she'll dig up something on you -â€Å" â€Å"My parents don't read the Daily Prophet. She can't scare me into hiding!† said Hermione, now striding along so fast that it was all Harry and Ron could do to keep up with her. The last time Harry had seen Hermione in a rage like this, she had hit Draco Malfoy around the face. â€Å"And Hagrid isn't hiding anymore! He should never have let that excuse for a human being upset him! Come on!† Breaking into a run, she led them all the way back up the road, through the gates flanked by winged boars, and up through the grounds to Hagrid's cabin. The curtains were still drawn, and they could hear Fang barking as they approached. â€Å"Hagrid!† Hermione shouted, pounding on his front door. â€Å"Hagrid, that's enough! We know you're in there! Nobody cares if your mum was a giantess, Hagrid! You can't let that foul Skeeter woman do this to you! Hagrid, get out here, you're just being -â€Å" The door opened. Hermione said, â€Å"About it-!† and then stopped, very suddenly, because she had found herself face-to-face, not with Hagrid, but with Albus Dumbledore. â€Å"Good afternoon,† he said pleasantly, smiling down at them. â€Å"We er we wanted to see Hagrid,† said Hermione in a rather small voice. â€Å"Yes, I surmised as much,† said Dumbledore, his eyes twinkling. â€Å"Why don't you come in?† â€Å"Oh†¦um†¦okay,† said Hermione. She, Ron, and Harry went into the cabin; Fang launched himself upon Harry the moment he entered, barking madly and trying to lick his ears. Harry fended off Fang and looked around. Hagrid was sitting at his table, where there were two large mugs of tea. He looked a real mess. His face was blotchy, his eyes swollen, and he had gone to the other extreme where his hair was concerned; far from trying to make it behave, it now looked like a wig of tangled wire. â€Å"Hi, Hagrid,† said Harry. Hagrid looked up. â€Å"‘Lo,† he said in a very hoarse voice. â€Å"More tea, I think,† said Dumbledore, closing the door behind Harry, Ron, and Hermione, drawing out his wand, and twiddling it; a revolving tea tray appeared in midair along with a plate of cakes. Dumbledore magicked the tray onto the table, and everybody sat down. There was a slight pause, and then Dumbledore said, â€Å"Did you by any chance hear what Miss Granger was shouting, Hagrid?† Hermione went slightly pink, but Dumbledore smiled at her and continued, â€Å"Hermione, Harry, and Ron still seem to want to know you, judging by the way they were attempting to break down the door.† â€Å"Of course we still want to know you!† Harry said, staring at Hagrid. â€Å"You don't think anything that Skeeter cow – sorry, Professor,† he added quickly, looking at Dumbledore. â€Å"I have gone temporarily deaf and haven't any idea what you said. Harry,† said Dumbledore, twiddling his thumbs and staring at the ceiling. â€Å"Er-right,† said Harry sheepishly. â€Å"I just meant-Hagrid, how could you think we'd care what that-woman-wrote about you?† Two fat tears leaked out of Hagrid's beetle-black eyes and fell slowly into his tangled beard. â€Å"Living proof of what I've been telling you, Hagrid,† said Dumbledore, still looking carefully up at the ceiling. â€Å"I have shown you the letters from the countless parents who remember you from their own days here, telling me in no uncertain terms that if I sacked you, they would have something to say about it -â€Å" â€Å"Not all of 'em,† said Hagrid hoarsely. â€Å"Not all of 'em wan me ter stay.† â€Å"Really, Hagrid, if you are holding out for universal popularity, I'm afraid you will be in this cabin for a very long time,† said Dumbledore, now peering sternly over his half-moon spectacles. â€Å"Not a week has passed since I became headmaster of this school when I haven't had at least one owl complaining about the way I run it. But what should I do? Barricade myself in my study and refuse to talk to anybody?† â€Å"Yeh – yeh're not half-giant!† said Hagrid croakily. â€Å"Hagrid, look what I've got for relatives!† Harry said furiously. â€Å"Look at the Dursleys!† â€Å"An excellent point,† said Professor Dumbledore. â€Å"My own brother, Aberforth, was prosecuted for practicing inappropriate charms on a goat. It was all over the papers, but did Aberforth hide? No, he did not! He held his head high and went about his business as usual! Of course, I'm not entirely sure he can read, so that may not have been bravery†¦.† â€Å"Come back and teach, Hagrid,† said Hermione quietly, â€Å"please come back, we really miss you.† Hagrid gulped. More tears leaked out down his cheeks and into his tangled beard. Dumbledore stood up. â€Å"I refuse to accept your resignation, Hagrid, and I expect you back at work on Monday,† he said. â€Å"You will join me for breakfast at eight-thirty in the Great Hall. No excuses. Good afternoon to you all.† Dumbledore left the cabin, pausing only to scratch Fangs ears. When the door had shut behind him, Hagrid began to sob into his dustbin-lid-sized hands. Hermione kept patting his arm, and at last, Hagrid looked up, his eyes very red indeed, and said, â€Å"Great man, Dumbledore†¦great man†¦.† â€Å"Yeah, he is,† said Ron. â€Å"Can I have one of these cakes, Hagrid?† â€Å"Help yerself,† said Hagrid, wiping his eyes on the back of his hand. â€Å"Ar, he's righ', o' course – yeh're all righ'†¦I bin stupid†¦my ol' dad woulda bin ashamed o' the way I've bin behavin'†¦.† More tears leaked out, but he wiped them away more forcefully, and said, â€Å"Never shown you a picture of my old dad, have I? Here†¦Ã¢â‚¬  Hagrid got up, went over to his dresser, opened a drawer, and pulled out a picture of a short wizard with Hagrid's crinkled black eyes, beaming as he sat on top of Hagrid's shoulder. Hagrid was a good seven or eight feet tall, judging by the apple tree beside him, but his face was beardless, young, round, and smooth – he looked hardly older than eleven. â€Å"Tha was taken jus' after I got inter Hogwarts,† Hagrid croaked. â€Å"Dad was dead chuffed†¦thought I migh' not be a wizard, see, ‘cos me mum†¦well, anyway. ‘Course, I never was great shakes at magic, really†¦but at least he never saw me expelled. Died, see, in me second year†¦.† â€Å"Dumbledore was the one who stuck up for me after Dad went. Got me the gamekeeper job†¦trusts people, he does. Gives 'em second chances†¦tha's what sets him apar' from other heads, see. He'll accept anyone at Hogwarts, s'long as they've got the talent. Knows people can turn out okay even if their families weren'†¦well†¦all tha' respectable. But some don understand that. There's some who'd always hold it against yeh†¦there's some who'd even pretend they just had big bones rather than stand up an' say – I am what I am, an' I'm not ashamed. ‘Never be ashamed,' my ol' dad used ter say, ‘there's some who'll hold it against you, but they're not worth botherin' with.' An' he was right. I've bin an idiot. I'm not botherin' with her no more, I promise yeh that. Big bones†¦I'll give her big bones.† Harry, Ron, and Hermione looked at one another nervously; Harry would rather have taken fifty Blast-Ended Skrewts for a walk than admit to Hagrid that he had overheard him talking to Madame Maxime, but Hagrid was still talking, apparently unaware that he had said anything odd. â€Å"Yeh know wha, Harry?† he said, looking up from the photograph of his father, his eyes very bright, â€Å"when I firs' met you, you reminded me o' me a bit. Mum an' Dad gone, an' you was feelin' like yeh wouldn' fit in at Hogwarts, remember? Not sure yeh were really up to it†¦an' now look at yeh, Harry! School champion!† He looked at Harry for a moment and then said, very seriously, â€Å"Yeh know what I'd love. Harry? I'd love yeh ter win, I really would. It'd show 'em all†¦yeh don' have ter be pureblood ter do it. Yeh don have ter be ashamed of what yeh are. It'd show 'em Dumbledore's the one who's got it righ', lettin' anyone in as long as they can do magic. How you doin' with that egg, Harry?† â€Å"Great,† said Harry. â€Å"Really great.† Hagrid's miserable face broke into a wide, watery smile. â€Å"Tha's my boy†¦you show 'em, Harry, you show 'em. Beat 'em all.† Lying to Hagrid wasn't quite like lying to anyone else. Harry went back to the castle later that afternoon with Ron and Hermione, unable to banish the image of the happy expression on Hagrid's whiskery face as he had imagined Harry winning the tournament. The incomprehensible egg weighed more heavily than ever on Harry's conscience that evening, and by the time he had got into bed, he had made up his mind – it was time to shelve his pride and see if Cedric's hint was worth anything.

Sterilization of Water

Project Report – Determination of the Dosage of Bleaching Powder Required for Sterilization of Different Samples of Water CONTENTS 1. INTRODUCTION 2. GENERAL METHODS USED 3. THEORY 4. REQUIREMENTS 5. PROCEDURE 6. OBSERVATION TABLES 7. CALCULATIONS 8. RESULT 9. CONCLUSION INTRODUCTION Water is the major constituent of all living beings. Water necessary to sustain all types of life. The water used for drinking purpose by human beings should full the following conditions : 1. It should be colourless. 2. It should not possess any smell. 3.It should contain any harmful dissolved salts such as nitrates, mercury salts, lead salts. 4. It should not be contain any living organism such as algae, fungus, bacteria etc. Sterilization of Disinfection of Water In order to obtain water for drinking purpose, water is first treated with alum whereby clay and other colloidal particles go precipitated the suspended impurities are then removed by filtration and the clear water obtained is subjecte d to some suitable treatment to destroy harmful germs and bacteria. These bacteria cause many dangerous disease such as cholera, thyroid, dysentery, tuberculosis, diphtheria etc.The process of killing the harmful bacteria by some suitable treatment of water is called STERILIZATION of DISINFECTION OF WATER. The common sterilizer agents are chlorine, ozone, bleaching powder, potassium per magnate chloramines. Sterilization of water through bleaching powder gives chlorine and if it is in excess, it is harmful for health and causes diseases like chlorawis, unconsciousness etc. So here we determine the exact amount of bleaching powder used of required for the sterilization of given samples of water. General Methods of Sterilizing WaterThere are many methods of sterilizing water but the best is one which gives sample of water which is totally free from germs. Sometimes potassium per magnate is used to disinfect water but it is not for drinking as it gives red colour and the excess of it i s in harmful for health. We use dissolve in water, so it can not be used in large scale. Another method for disinfection is by simply boiling the water for about 15 minutes, but this powder. The chemical action of bleaching powder on germs and bacteria is due to the chlorine which becomes available, when it is added to water.So here in the present context, we shall focus on disinfection of water using bleaching powder. Theory Objective :  Our objective of this project is to determine the amount of bleaching powder required for the sterilization of given samples of water. So certain steps are taken in the context as follows :- 1- A known mass of the given samples of bleaching powder is dissolved in water to prepare a solution of known concentration. This solution contains dissolved chlorine, liberated by the action of bleaching powder with water. CaOCl2  + H2O ——————-> Ca(OH)2  + Cl2 – The amount of chlorine present in the above solution is determined by treating a known volume of the above solution with excess of 10% potassium iodide solution, when equivalent amount of iodine is liberated. The iodine, thus liberated is then estimated by titrating it against a standard solution of sodium thiosulphate using starch solution as indicator. Cl2  + 2KI ——————–> 2KCl + I2 I2  + 2Na2S2O3  Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€Ã¢â‚¬â€> Na2S4O6  + 2NaI 3- A known volume of one of the given samples of water is treated with a known volume of bleaching powder solution.The amount of residual chlorines is determined by adding excess potassium iodine solution and then titrating against standard sodium thio-sulphate solution. 4- From the reading in 2 and 3, the amount of chloring and hence bleaching powder required for the disinfection of a given volume of the given sample of water can be calculated. Requirements for the Experimental Determination Requirements are as follows : Apparatus : 1. Burette 2. Titration Flask 3. 500 ml measuring flask 4. 100 ml Graduated Cylinder 5. 250 ml Measuring flask 6. 1lt. Measuring flask 7. Glazed Tile 8. Glass Wool. Chemicals : 1.Bleaching powder -5gm. 2. Na2SO4—->12. 4 gm. 3. KI – 25gm. 4. Different Sample of Water 5. Distilled Water 6. Soluble starch – 1gm. 7. Indicator – Starch Solution. Procedure : 1- Preparation of N/20 Na2SO4  solution : Take 12. 4 gm of sodium thio-sulphate hydrated and mix it in about 500ml of water then the mixture is diluted to make the volume 1000ml. or 1lt. Normality = strength/Molecular Mass. = 12. 4 / 248 = 1/20N 2- Preparation of 10%KI solution: Take 25gm. of KI powder and mix it in about 100ml of water then dilute the mixture to make the volume 250 ml and take it in the measuring flask. – Preparation of Bleaching Powder solution : Weight 5gm of bleaching powder and mix it in about 200 ml of distilled water in a conical flask. Stopper the f lask and shake it vigorously. The suspension thus obtained is filtered through glass wool in measuring flask of 500ml. and dilute the filtrate with water to make the volume 500 ml. The solution of obtained is 1% bleaching powder of solution. 4- Preparation of starch solution : Take about 1gm of soluble starch and 10 ml of distilled water in a test table mix vigorously to obtain a paste. Pour the paste in about 100ml. of hot water contained in a beaker with constant stirring.Boil the contents for 4-5min. and then allow to cool. 5- Take 100ml. of distilled of water and then 20ml of bleaching powder of solution in a stopper conical flask and add it 20ml of 10% KI solution. Shake the mixture, titrate this solution against N/20 Na2S2O3 Solution taken in burette. When solution in the conical flask becomes light yellow in colour add about 2ml of starch solution as indicator. The solution now becomes blue in colour. The end point is disappearance of blur colour, so continue titrating till t he blue colour just disappears. Repeat the titration to get a set of three readings. – Take 100ml of water sample in a conical flask and add 20ml of KI solution and stopper the flask. Shake it and titrates against N/20 Na2S2O3  until the solution become yellow. Then add 2ml of starch solution and then again titrate till the blue colour disappears. Repeat titration for three readings. 7- Repeat the step 6 with other samples of water and records the observation.

Volume of bleaching powder solution used to disinfect 100ml of water = 1. 6 x 20/7. 7ml. 1. 6 x 20/7. 7 ml. of bleaching powder solution =1. 6 x 20 x 0. 01 gm / 7. 7 =  0. 4156 gm Calculations : Sample II (POND WATER) :- Amount of bleaching powder used to disinfect 100ml of water. = (7. 7 – 5. 2) ml of 0. 2 N Na2S2O3  solution = 2. 5ml 1ml of bleaching powder solution contains bleaching powder = 0. 1 gm. 7. 7ml. of 0. 2N Na2S2O3  = 20ml of bleaching powder solution So 1ml of Na2S2O3  = 20ml. of bleaching powder solution. Volume of CaoCl2  solution required to disinfect 100ml of water. = 2. 5 x 20/7. 7 ml. 2. 5 x 20/7. 7 ml. of bleaching powder solution. = 2. 5 x 20 x 0. 01 gm / 7. 7 of bleaching powder Amount of bleaching powder required to disinfect 1 let. of wate r. = 2. 5 x 20 x 0. 01 x 1000 / 7. 7 x 100 = 25 x 2/7. 7 =  0. 6493 gm. Calculations : Sample III (TANK WATER) :- Amount of bleaching powder used to disinfect 100ml of water. = (7. 7 – 5. 5 ) = 2. 2ml of 0. 2 N of Na2S2O3  solutions. ml of bleaching powder solution contains bleaching powder. = 5/500 = 0. 01gm 7. 7 ml. of 0. 2 N Na2S2O3  = 20ml of bleaching powder solution. so 1ml of 0. 2 N Na2S2O3  solution = 20/7. 7 ml volume of bleaching powder solution used to disinfect 100ml of water = 2. 2 x 20/7. 7 ml. 2. 2 x 20/7. 7 ml of bleaching powder solution = 2. 2 x 20 x 0. 01 gm / 7. 7 of bleaching powder Amount of bleaching powder used to disinfect 1 ltr. of water = 2. 2 x 20 x 0. 01 x 1000 / 7. 7 x 100 = 22 x 2/77 =  0. 5714gm Results Amount of the given samples of bleaching powder required to disinfect one liter of water :- Samples I = 0. 4156Samples II = 0. 6493 Samples III = 0. 5714 Thus we get the amount required for disinfection and if bleaching powder is taken less than this amount water will remain impure and if it taken in excess than this will also be harmful as it will contain chlorine. The results shows that Samples II is the imputes water as the amount of bleaching powder requires is maximum and Sample I is less impure than others as the bleaching powder used is minimum. The tables also show the difference. Titration III has minimum reading because of impurities and titration I has maximum reading because the sample was distilled water.Conclusion : This is the convenient method of sterilizing water.
