The Devil as Iago in Shakespeare’s Othello Essay -- GCSE Coursework Sh

The Devil as Iago in Shakespeare’s Othello    One question that has often been debated amongst literary scholars is what could have motivated Iago to set off such a chain of events which accumulated in the horrific amount of death and tragic consequences that occur in William Shakespeare’s play Othello. On the surface, one could artificially assume that Iago was spurred by two reasons to carry out such a malicious and inhumane plan. His anger of being passed over for lieutenantship by Othello in favor of Cassio, coupled with his inclinations that his wife has slept with Othello, drives Iago to partake in dangerous and seemingly insurmountable actions in order to climb up the social ladder and exact revenge on Othello. Chief proponents of this belief that Iago was solely motivated by these two factors would argue that he was simply a Machiavellian-inspired villain who took action only in the devised betterment of himself and his current status. However, when one delves into Iago’s unholy actions and intentions on a deeper level, it is clear that a metaphysical element exists in his character that when revealed is utterly haunting and truly horrific. A more penetrating analysis of Iago shows that he is not only the embodiment of evil but that he is in fact the Devil himself, who is set on destroying everything that is good in the lives of Othello’s characters. A main underlying theme that resides in Othello is Shakespeare’s constant usage of outward appearance as opposed to reality. It is Iago, who in the opening act of the play, makes this clearly obvious to the audience stating "I am not what I am"(1.1.65). Although it is not yet revealed to the audience who Iago really is (i.e. the Devil), this statement is a direct rev... ...o: Greenhaven Press, 1996. Reprint from Literature.

Papaya Sap

Introduction Rubber is an elastic hydrocarbon polymer which occurs as a milky emulsion (known as latex) in the sap of a number of plants but can also be produced synthetically. The major commercial source of the latex used to create rubber is the Para rubber tree, Hevea brasiliensis (Euphorbiaceae). This is largely because it responds to wounding by producing more latex. Other plants containing latex include figs, euphorbias and the common dandelion.These have not been a major source of rubber, though when Germany was cut off from supplies of rubber during World War II, attempts were made to use such sources, before being supplanted by the development of synthetic rubber. It is believed to have been named by Joseph Priestley, who discovered in 1770 that dried latex rubbed out pencil marks. In its native Central America and South America, rubber has been collected for a long time. The Mesoamerican civilizations used rubber mostly from Castilla elastica.The Ancient Mesoamericans had a ball game using rubber balls (see: Mesoamerican ballgame), and a few Pre-Columbian rubber balls have been found (always in sites that were flooded under fresh water), the earliest dating to about 1600 BC. According to Bernal Diaz del Castillo, the Spanish Conquistadores were so astounded by the vigorous bouncing of the rubber balls of the Aztecs that they wondered if the balls were enchanted by evil spirits. The Maya also made a type of temporary rubber shoe by dipping their feet into a latex mixture.Rubber was used in various other contexts, such as strips to hold stone and metal tools to wooden handles, and padding for the tool handles. While the ancient Mesoamericans did not have vulcanization, they developed organic methods of processing the rubber with similar results, mixing the raw latex with various saps and juices of other vines, particularly Ipomoea alba, a species of Morning glory. In Brazil the natives understood the use of rubber to make water-resistant cloth.A story sa ys that the first European to return to Portugal from Brazil with samples of such water-repellent rubberized cloth so shocked people that he was brought to court on the charge of witchcraft. When samples of rubber first arrived in England, it was observed that a piece of the material was extremely good for rubbing out pencil marks on paper. This was the origin of the material's English name of ‘rubber'. Blocks of the material are still used for this purpose, and known as ‘rubbers' in England, causing occasional amusement to Americans, to whom a ‘rubber' is a condom.The sap is any liquid found in the stems of plants, including the liquid material that moves the younger annual rings and bark of trees and watery juices of herbaceous plants. Natural rubber is another valuable sap. The papaya’s milky sap is also called latex. Latex is a milky fluid produced by rubber trees. Latex is also used to make rubber Since papaya fruits produce latex like rubber plants, th e study â€Å"Rubber Material Source from Papaya (Carica papaya) Milky Sap† was formulated.The study aimed to use papaya sap as main ingredient in making bioplastic because it contains starch which is one of the components in making bioplastic and also, the sap or latex is used in making rubber. Papaya is found anywhere so there is adequate supply of the main ingredient. Plus, the flow of the papaya sap is continuousand it is environment friendly because it doesn’t harm the plant. The study is to be conducted to produce bioplastic so that the plastics that people are using in the present could somehow be replaced with the use of this investigatory project to lessen the environmental effects of the decomposition of plastics.Objectives of the Study This investigation is anchored on the following objectives: 1) To evaluate and compare the, the appearance, texture, elasticity and strength of the rubber material. 2) To compare the experimental rubber material from the three treatments and the commercial rubber material. 3) To identify which among the three treatments made will be least fot the production of the wrapper. Statement of the Problem 1. Is there a significant difference between the experimental Rubber material and commercial Rubber material when analyzed by: 1. Appearance 1. 2 Texture 1. 3 Elasticity 1. 4 Strength 2. Is there a relationship between the cost of the experimental rubber material and commercial rubber material? 3. Is there a significant difference between the treatments’ replications when analyzed by: 1. 1 Appearance 1. 2 Texture 1. 3 Elasticity 1. 4 Strength Hypotheses of the Study Null Hypothesis 1. There is no significant difference between the experimental rubber material and commercial rubber material when analyzed by appearance, texture, elasticity, and strength. 2.There is no significant relationship between the cost of the experimental rubber material and commercial rubber material. 3. There is no significant dif ference between the treatments’ replications when analyzed by appearance, texture, elasticity, and strength. Alternative Hypothesis 1. There is a significant difference between the experimental rubber material and commercial rubber material when analyzed by appearance, texture, elasticity, and strength. 2. There is a relationship between the cost of the experimental rubber material and commercial rubber material. 3.There is a significant difference between the treatments’ replications when analyzed by appearance, texture, elasticity, and strength. Significance of the Study Rubber Manufacturers- can help in reducing the product cost of a certain material out of rubber. And also, it can help in preventing the emission of harmful gases that can cause depletion of the ozone layer and in the worsening of global warming. Consumers- they can be assured that the product is safe and does not contain hazardous chemicals that can harm their health. And also, it is biodegradable, so it is not difficult for them to dispose it.Scope and Limitations of the Study Variable Limitation The independent variable of the study is the papaya sap, the dependent variable of the study is the produced rubber material and the moderator variables of the study were the processes involved in making the rubber material.

Review of Related Literature Rubber Used in the study as dependent variable.. Rubber any solid substance that upon vulcanization becomes elastic; the term includes natural rubber ( caoutchouc ) and synthetic rubber.The term elastomer is sometimes used to designate synthetic rubber only and is sometimes extended to include caoutchouc as well. Chemistry and Properties All rubberlike materials are polymers , which are high molecular weight compounds consisting of long chains of one or more types of molecules, such as monomers. Vulcanization (or curing) produces chemical links between the loosely coiled polymeric chains; elasticity occurs because the chains can be stretched and the crosslinks cause them to spring back when the stress is released. Natural rubber is a polyterpene, i. e. it consists of isoprene molecules linked into loosely twisted chains. The monomer units along the backbone of the carbon chains are in a cis arrangement (see isomer ) and it is this spatial configuration that gives rubber its highly elastic character. In gutta-percha , which is another natural polyterpene, the isoprene molecules are bonded in a trans configuration leading to a crystalline solid at room temperature. Unvulcanized rubber is soluble in a number of hydrocarbons, including benzene, toluene, gasoline, and lubricating oils. Rubber is water repellent and resistan t to alkalies and weak acids.Rubber's elasticity, toughness, impermeability, adhesiveness, and electrical resistance make it useful as an adhesive, a coating composition, a fiber, a molding compound, and an electrical insulator. In general, synthetic rubber has the following advantages over natural rubber: better aging and weathering, more resistance to oil, solvents, oxygen, ozone, and certain chemicals, and resilience over a wider temperature range. The advantages of natural rubber are less buildup of heat from flexing and greater resistance to tearing when hot ( http://www. ncyclopedia. com/topic/rubber. aspx ). Starch Starch is the binding component in the study. Starch or amylum is a carbohydrate consisting of a large number of glucose units joined together by glycosidic bonds. This polysaccharide is produced by all green plants as an energy store. It is the most important carbohydrate in the human diet and is contained in such staple foods as potatoes, wheat, maize (corn), ric e, and cassava.. Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin. [1] Glycogen, the glucose store of animals, is a more branched version of amylopectin. Starch is processed to produce many of the sugars in processed foods. When dissolved in warm water, it can be used as a thickening, stiffening or gluing agent, giving wheatpaste ( http://en. wikipedia. org/wiki/Starch ). Papaya Sap Papaya sap is the independent variable of the study.The latex of the papaya plant and its green fruits contains two proteolytic enzymes, papain and chymopapain. The latter is most abundant but papain is twice as potent. In 1933, Ceylon (Sri Lanka) was the leading commercial source of papain but it has been surpassed by East Africa where large-scale production began i n 1937. The latex is obtained by making incisions on the surface of the green fruits early in the morning and repeating every 4 or 5 days until the latex ceases to flow. The tool is of bone, glass, sharp-edged bamboo or stainless steel (knife or raxor blade).Ordinary steel stains the latex. Tappers hold a coconut shell, clay cup, or glass, porcelain or enamel pan beneath the fruit to catch the latex, or a container like an â€Å"inverted umbrella† is clamped around the stem. The latex coagulates quickly and, for best results, is spread on fabric and oven-dried at a low temperature, then ground to powder and packed in tins. Sun-drying tends to discolor the product. One must tap 1,500 average-size fruits to gain 1 1/2 lbs (0. 68 kg) of papain (http://www. hort. purdue. edu/newcrop/morton/papaya_ars. html#Papain).Glycerin Glycerin is the plasticizer and the preservative to the product. Glycerin is a thick liquid that is colorless and sweet tasting. It has a high boiling point an d freezes to a paste. Glycerin's most common use is in soap and other beauty products like lotions, though it is also used, in the form of nitroglycerin, to create dynamite. Glycerin is popular in beauty products because it is a humectant — it absorbs ambient water. This means that it can help seal in moisture. Not only is it used in the soap making process, it's a byproduct too.Many soap manufacturers actually extract glycerin during the soap making process and reserve it for use in more expensive products. Even when soap manufacturers reserve glycerin for other products, however, some amount of glycerin remains in every bar of soap (http://www. wisegeek. com/what-is-glycerin. htm). Vinegar Vinegar is an acidic liquid produced from the fermentation of ethanol in a process that yields its key ingredient, acetic acid (ethanoic acid). It also may come in a diluted form. The acetic acid concentration ypically ranges from 4% to 8% by volume for table vinegar[1] and up to 18% for pickling. Natural vinegars also contain small amounts of tartaric acid, citric acid, and other acids. Vinegar has been used since ancient times and is an important element in European, Asian, and other cuisines. The word â€Å"vinegar† derives from the Old French vin aigre, meaning â€Å"sour wine†, which in turn is derived from the Latin â€Å"vinum aegrum† meaning â€Å"feeble wine† ( http://en. wikipedia. org/wiki/Starch ).

The Professional Application Of Psychology - 2165 Words

Applied psychology is the professional application of psychological knowledge using theory and findings to solve practical problems in important areas of the human environment, such as education, health and the workplace (Coolican, 2007, p. 1). There are many branches of applied psychology including Clinical, Occupational, Educational, Forensic, Health, Sport Exercise, Counselling and Neuropsychology. This essay will provide a discussion of the theory that underlines Clinical and Educational psychology, along with possible ethical considerations associated with the professional practice in each of the two applied settings. Clinical psychology is defined as the branch of psychology responsible for treating and understanding mental health problems such as anxiety disorders (Davey, 2011, p.2) - the World Health Organisation (WHO), define mental health as â€Å"a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity† (WHO webs ite 2014). Educational psychology applies psychological theories, research and techniques in order to establish a systematic body of knowledge concerning the factors which influence learning and behaviour within an educational context (Coolican, 2007, p. 73). One essential element of practicing psychology is the need for ethical standards to be met. The guide for monitoring ethical standards is provided by the Society’s Code of Conduct (BPS, 2000).
