Elements, Mixtures and Compounds - Essay Example For example, a mixture of iron and sulfur can be taken in any proportion while a compound such as iron (II) sulfide always has a ratio of 7 : 4 by mass of iron and sulfur (Leong & Aik, 2009). When a mixture is prepared by mixing two or more substances, there is no chemical exchange involved and there is absence of heat or light production. When a compound is prepared, it is usually accompanied with a chemical change in which some heat, light or both are liberated. For example, when a mixture is prepared by mixing iron filings and sulfur, no heat is liberated. However, when hot iron filings and sulfur are taken together in a test tube, a chemical reaction occurs resulting in the formation of iron sulfide (Fe + S ?FeS). The test tube glows red because of heat produced during the reaction (Leong & Aik, 2009). The properties of a mixture are characteristic of the individual substances mixed. On the contrary, the properties of a compound are very different from those of the original eleme nts. For example, in a mixture of iron filings and sulfur, properties such as magnetism, color, texture of the individual substances are retained. Iron sulfide, a compound, has very different properties from those of iron and sulfur. It lacks magnetic activity and also has different physical and chemical properties (Leong & Aik, 2009). ... 2) Supposed that you have a pure substance, how can you tell whether it is a compound or an element?   An element cannot be further broken down chemically, while a compound can be broken down into individual components or elements using chemical reactions specific for that compound. For example, heating mercuric oxide, which is a compound, over a Bunsen flame, will result in the decomposition and separation of mercuric oxide into mercury and oxygen. However, mercury and oxygen, which are elements, cannot be further broken down using any chemical means (Leong & Aik, 2009). Therefore, in order to tell whether a given pure compound is an element or a compound, it will be subjected to various separation procedures to determine if it can be broken down further. Its melting and boiling points and other physical and chemical properties will also be noted and compared with those of preexisting elements and compounds for ease of identification. 3) What is the difference between an ionic and a covalent bond? Chemical bonds such as ionic and covalent bonds determine the properties of a compound. The main differences between the two kinds of bonds are discussed as follows: Ionic bond is formed when electrons are transferred from one atom to another. The transfer of electrons results in the formation of a positive and a negative ion that are held together by strong electrostatic attraction. For example, salt (NaCl) is formed when an electron from sodium (Na) is transferred to chlorine (Cl) to form ions (Na+ and Cl- ) that are held together to form salt (NaCl). Covalent bond is formed when an electron pair from the outer shell is shared between two atoms. For instance, Hydrochloric acid

Renoirs adaptation of maupassants A counrty excursion Essay

Renoirs adaptation of maupassants A counrty excursion - Essay Example In the context of French cinema, works of such iconic writers as Victor Hugo, Emile Zola and Alexander Dumas were heavily drawn upon. Guy de Maupassant’s short story A Country Excursion is one among many instances of early cinema embracing literature. But there are numerous challenges in adapting a work of art to a radically different medium. Theatre and cinema can be said to share some affinity in terms of principles of mise-en-scene, accepted rules of screen-play, shared exploration of genres, etc. But literature to film is a big leap and film theorist Dudley Andrew identifies three basic types of adaptation – borrowing, intersecting and transforming sources. In the case of A Day in the Country to varying degrees all the three types are at play. Borrowing: The film is said to be borrowed from the short story to the extent that there is divergence in their details pertaining to characterization, geographic description, projection of individual motive, etc. In borrowing , â€Å"the artist employs, more or less extensively, the material, idea, or form of an earlier, generally successful text...the adaptation hopes to win an audience by the prestige of its borrowed title or subject...at the same time it seeks to gain a certain respectability, if not aesthetic value, as a dividend in the transaction†. (Andrew, p.422) Renoir’s work satisfies some of these criteria better than others. Certainly the literary work is the very basis for the project of the film. Moreover, Maupassant was a household name in early twentieth century France, and thus brings a degree of prestige to the project at hand. But the particular short story, A Country Excursion, does not have the same name recollection as its author does. Renoir’s enterprise does succeed in fulfill the twin key criteria of bringing respectability and aesthetic value to the transaction. The cinema produced is no injustice to the artistic standards of its source. The additional provis ions afforded by the new medium add more vibrancy and color to the source text. So the idea of the film can certainly be said to have been borrowed, though with certain qualifications. Intersection: This form of adaptation is found to be the weakest in A Day in the Country. Intersection is the most infidel methods of transmuting words to film due to its limited objective. The goal of the filmmaker is less constrained, for he/she is not concerned with the entire written work but only one idea/feature within it. The task then is to experiment and find out what ‘cinema’ as a medium can ‘do’ to the original. At its heart is creative curiosity and experimentation on the part of the director. Renowned French film critic Andre Bazin has expressed intersection through the metaphor of light. Andrews paraphrases Bazin thus, â€Å"here the original artwork can be likened to a crystal chandelier whose formal beauty is a product of its intricate but fully artificial ar rangement of parts while the cinema would be a crude flashlight intersecting not for its own shape or the quality of its light but for what it makes appear in this or that dark corner† (Andrews, p.423) Seen in light of this definition, A Day in the Country is the cinematic intersection of the literary work, for it brings to the table unique cinematic qualities of expression. This is most evident in passages in the film where dialogue takes

Motivated by applications Essay Example for Free

Motivated by applications Essay Until the last century, mathematics was always motivated by applications (Kline, 1973: iv); it took humanity an enormous time span to reach the abstraction capacity necessary to become interested in ‘pure’ mathematics. It follows that children take some time to reach the necessary mental maturity to deal with the formalism and type of thinking involved in abstracts and mathematics. It is interesting to note that in many countries, 21 (the end of this 7-year period) is the age for a young person to become legally responsible. It is a recognition, that only at this age are all human capacities fully available, and the individual is able to control and be totally responsible for his or her actions (Steiner, 1982; Talbot, 1995 and Bronfenbrenner, 1995). In conclusion, this paper supported my aim to prove that the extensive implementation of computers in pre-high school education is having a detrimental effect on the development of children. The first argument I presented to support my aim is that computer technology is ecological and like all technology may have long reaching effects on children’s emotional, psychological, spiritual, moral and social sensibilities. Fostering a mechanical, rational view of social relationships. Secondly, I argued that a computer is a tool, and to be effective it is necessary children understand what it is and how it works. Just as a childs physical development is stunted when muscles are not exercised, the development of disciplined thinking is stunted when the computer relieves the child of the responsibility for planning and organizing his/her thoughts before expressing them. It should be kept in mind that tools designed to aid the mature mind may hinder the maturation of the developing mind. Thirdly, I supported my aim by arguing that computers work with an extremely restricted class of children’s thoughts. It was demonstrated that early computer use and an emphasis on computer like thinking, is leading childrens development to be dominated by the rigid, logical, algorithmic thinking, that is characteristic of computer interaction. This accelerated, but isolated intellectual development, brings a childs mental abilities to an adult level long before they have grown strong enough to restrain it and give it humane direction. The fourth argument presented to support my aim was, that how computers are used in education is detrimental to children’s development. Children need time for active, physical play; hands-on lessons of all kinds, especially in the arts; and direct experience of the natural world. The prevalent emphasis on technology is diverting us from the urgent social and liberal educational needs of children. A proper education requires attention to students from good teachers and active parents. It requires commitment to developmentally appropriate education and attention to the full range of childrens needs; physical, emotional, and social, as well as cognitive. Finally and most importantly I demonstrated that developmental stages in children are not compatible with computer use. Combining Steiner, Bloom and Krathwohl developmental concepts with the fact that computers are mathematical tools, forcing a purely abstract and mathematical type of thinking as well as use of symbolic formal language. Applying these concepts and properties of computers to proper educational goals we may surmise that they are unsuitable for extensive use by children in any form before approximately age 15, or high school. Convincing arguments have been presented to prove the extensive implementation of computers in pre-high school education is having a detrimental effect on the development of children.

English Macbeth :: essays research papers

To What Extent is Macbeth pushed into killing king Duncan? Numerous people and factors push Macbeth into killing the king. The main factors are:  Lady Macbeth  The Witches and Fate  King Duncan  Banquo  Himself (Macbeth) I start with probably the most influential character upon Macbeth, his wife, Lady Macbeth. Lady Macbeth believes what the witches have said and therefore believes that she will become the queen. ‘Have I thought good to deliver thee’ She obviously has a great ambition and will do almost anything to fulfil her ambition. This shows a great evilness in her ‘And dashed the brains out’ She is also reluctant to accept Macbeths original thought of leaving the idea alone ‘What beast was’t then that made you break this enterprise to me’ She appears supremely confident about murdering Duncan even though Macbeth is not which also shows of her great ambition to succeed and become queen of Scotland. ‘We Fail? … But screw your courage… and we’ll not fail’ Lady Macbeth plans the murder from a very early stage even when Macbeth is unsure of what he is to do ‘When Duncan is asleep… his spongy officers, who shall bear the guilt of our great quell? Overall Lady Macbeths ambition, confidence and naivete is perhaps the major factor in pushing Macbeth into the murder of Duncan. She does not think of the consequences of the murder so she is 100% behind Macbeth killing Macbeth, which makes it difficult for Macbeth to go against her. Another factor is Banquo. The fact that Banquo knows of what the ‘imperfect speakers’ said is a major factor pushing Macbeth away from killing the King. If the King were to be murdered Banquo would be suspicious and would most likely suspect Macbeth of doing the evil deed of killing the king. This would obviously put Macbeth off. Another factor is that of the Witches. Without them Macbeth would most likely not think twice about killing the king. ‘All hail Macbeth, that shalt be king thereafter’ If someone were to just tell him this he would most likely not believe it but it was the fact that the witches had forecasted that he would be Thane of Cawdor and Thane of Glamis correctly. The witches forced him to think about being king but at first he expected to be made king without doing anything for it but he then realises there is only one way, to kill the king. This encounter with the witches has put him in two minds.

Harry Frankfurt

Harry Frankfurt defined the principle of alternate possibilities ( PAP ): A person is morally responsible for his actions if he couldn t have done otherwise . And he argued as follows 1) ( PAP) is true 2) determinism : every event must be the way it is and we couldn t do otherwise is also true Conclusion: ( PAP ) and determinism are not compatible This argument is a valid argument but it is not a sound one because the author doesnot agree with the conclusion of the argument and since it is a valid argument so he decides that one of the premises is false and doubts the first premise . By giving us an example he will try to convince us that the (PAP) is false . He states that Jones does action (A) and that Black is some kind of manipulator that has the ability to manipulate Jones so he can inhibit Jones from performing actions other than (A) without Jones knowing that black exists . Black will manipulate only if Jones is going to decide to do otherwise , so we conclude that Jones couldn t have done otherwise because of Black , nevertheless Jones is morally responsible for action (A) because he did all on his own without the interference of Black. This example contradicts with definition of (PAP) . because jones is morally responsible even though he couldn t have done otherwise. Moreover I think it is wise to add an argument here : 1)Jones is morally responsible for his action (A) )Jones couldn t have done otherwise ( in other words his actions are determined ) We conclude that moral responsibility is compatible with determinisim . One thing that I noticed from the example is that black s duty or job is to block or inhibit jones choices of actions other than action (A) . therefore the author admits that there are other choices of actions ( possible alternatives ) than action (A) , so possible alternatives is true but we have to find the right definition and appli cation for it .

Anatomy Of The Human Body - 1334 Words

Introduction:- Human physiology studies the physical and biochemical processes that support the body s function while anatomy studies the structures of the human body. Anatomy is divided into two parts which are histology: this is the atomic study of tissues and Cytology is the atomic study of cells. This unit focuses on both the anatomic feature this involves the morphology and forms of the part of the body and physiological features of the human body this involves the function of the part of the body on a regular basis.

Digestive system allows the body break down food into different essential nutrients to be d igested. This happens when transformation of vital nutrients and energy that are the important source for nourishing the body and its related functions. (Inner Body, 2016). Stages of digestion involves Ingestion which is the first stage where food intake takes place via the mouth. Then Secretion is when these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile. Swallowing. This process involves smooth and skeletal muscles in the mouth, tongue, and pharynx to shove food out of the mouth via the pharynx into the esophagus. 3 Respiratory system: It consist of three main parts which are the airway, the lungs, and the muscles. The airway includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. The oxygen passes via the lung into the body and carbon dioxide exit the body. Muscles includes the diaphragm and intercostals muscles. The function of respiratory system is for Gaseous exchange to occur between the human body and the environments by which inhaling of Oxygen from air and exhaling Carbon-Dioxide and water are released into the atmosphere (Agostoni, 1964) 4.

Functionalism And Its Impact On Society - 1119 Words

In this paper I will explain and argue for Functionalism. Functionalism allows for a scientific approach to the mind-body problem, while maintaining the integrity of mental and physical states and attributing them to the functional roles they play within the bodily system. The main argument for Functionalism is founded on the basis that it fulfills all of the requirements for an effective form of Physicalism. 1. In order for a physicalist argument to be effective: it must account for mental states being defined by their role; allow for mental and functional types to be defined circularly/holistically; and allow mental states to be realized in a multitude of outcomes. Functionalism sufficiently ensures all of these predicates. Functionalism is an adequate form of physicalism. Like other arguments for physicalism, functionalism is based on the notion that everything that exists in reality is physical in form. One of the main distinctions that makes the functionalist approach unique is its method of defining objects. For example, many simple things are defined by what they’re made of, such as gold is simply Au. However more complex things are defined in terms of what their functions are. A heart is defined as an object that pumps blood around an organism’s body, regardless of what it is made of.
