Battleship Potemkin versus the Birth of a Nation Essay

Aside from the similar visual styles of Battleship Potemkin and The Birth of a Nation, both films are examples of civil unrest during periods of political instability in a historical setting. Both movies take place during a national revolution and involve several instances of social turmoil and disturbance. The styles of these films can be contrasted by viewing their use of montage, focus, and basic film techniques in relation to thematic and constructive plot elements. The Birth of a Nation is a story about the consequences of the Civil War on the friendship of a northern and southern family. It expresses the effects of the war on their lives in relation to major historical and political events. This movie is directed by D.W.†¦show more content†¦An intense fascination with the editing style of D.W. Griffith led the director, Sergei Eisenstein, to create this film in the style that he did, and to transform the dynamic tension created by cross-cutting and parallel editing into the modern idea of the montage. This film employs the revolutionary use of montage as a furtherance of the collisions of ideas as symbolic representation. Historically, these films were reflections of true events that happened in the not so distant past. Both are propagandistic in nature, although only Potemkin was made to intentionally draw on the events it portrayed as a glorification of the past. Eisenstein felt that he could realistically commemorate the 1905 revolution in film form. Griffith, however, simply wanted to create a film that was a reflection on history. Although he did not intend for his film to be considered racist or condone the actions of the KKK, he does expressly cite his right to examine the ?dark side of wrong? in a plea on the opening title card of the film. (Dirks, ?The Birth of a Nation?) There is a scene in both films that is used as a representation to foreshadow the impending events. In Griffith?s work, the shot that is used to establish the premise of the film comes during a scene of a kitten being dropped in between two puppies on the southern plantation and the subtitle ?Hostilities.? This is an allusion to the ominous polarity

Francisco De Zubar N And His Work English Literature Essay Free Essays

Francisco de Zurbaran, a Spanish painter was born in Fuentes de Cantos, Badajoz Province in Estremadura and baptized on Nov. 7, 1598. His male parent was a comfortable tradesman of Basque descent. We will write a custom essay sample on Francisco De Zubar N And His Work English Literature Essay or any similar topic only for you Order Now In 1614, Zurbaran ‘s male parent sent him to Seville to apprentice for three old ages to a second-rate painter of images, Pedro Diaz de Villanueva. Zurbaran opened a workshop in Llerena in 1617 and married a adult female older than himself. She died after holding three kids. He was married once more to a widow in 1623. During his 11 old ages in Llerena, Zurbaran ‘s piousness was influenced by Spanish Quietism, which was a spiritual motion that taught inner backdown, the find of God in meekly submissive silence, and the usage of penitentiary exercisings to repress the senses and quiet the mind. Although this influence had a deep consequence on his art, it in no manner limited his artistic creative activities. The contracts for this period are so legion that he would hold been obliged to delegate many of them to helpers. In add-on, he was transposing to Seville to put to death plants for the Dominican, Trinitarian, Mercedarian, and Franciscan monasteries. In 1629, the Sevi lle Town Council persuaded Zurbaran to travel his workshop to their metropolis. He arrived with his married woman, kids, and eight retainers. The undermentioned twelvemonth the painters ‘ Guild of St. Luke ordered him to subject to an scrutiny and he refused. The town council ended up back uping him. His frequenters continued to be largely monasteries including the Capuchins, Carthusians, and Jeronymites were added to the list. In April 1634, the painter Diego Velazquez, who was in charge of the ornaments for the new Royal Palace in Madrid, commissioned Zurbaran to put to death for the Hall of Realms two conflict scenes, which were to belong to a series that included Velazquez ‘s Surrender of Breda, and 10 Labors of Hercules. Zurbaran returned to Seville in November with the honorary rubric of Painter to the King and the happy memory that Philip IV had called him the male monarch of painters. Zurbaran was at a extremum of creativeness and felicitousness in 1639, when his married woman died. His art production declined markedly and his manner became graver. He married for the 3rd clip, in 1644, but his artistic star was falling. Missing sufficient committees at place, Zurbaran was obliged to make the bulk of his plants for South America. With four more kids born of his new matrimony, he sold Flemish landscapes and pigments and coppices to the South American market. He continued to bring forth largely for South America until 1658, when he decided to seek to alter his fortune in Madrid. His art, nevertheless, was small apprehended at that place. Zurbaran died destitute in Madrid on August 27, 1664. Zurbaran ‘s work was really sophisticated with accurate pragmatism and indefinable mysticism. Zurbaran chose to be a painter of spiritual topics. His work was ever created big. Other effects are attained by the elaborate finished foregrounds which mass out mostly in visible radiation and shadiness. He was really adept in painting figures with curtain as shown in one of his works The Annunciation. He worked with oil pigments and most of his plants were spiritual scenes and portrayals. Two-thirdss of his plants were painted in the 1630 ‘s and the other 3rd is about every bit divided before and after that decennary. The Annunciation was painted in 1650 with oil on canvas. It measures about 85 inches tall and about one-hundred and 24 inches broad. â€Å" This Annunciation falls rather late in Zurbaran ‘s calling, when his simple and disconnected mold, dark to visible radiation, begins to soften and film over. His pallet becomes less blatant and more blended, while the about militaristic urgency of his earlier work is replaced by an familiarity and tenderness. The walls of the Virgin Mary ‘s room literally dissolve in a inundation of cherubs bathed in visible radiation, as the angel Gabriel with great heroism and discretion announces that she is with kid † says Joseph J. Rishel. Francisco de Zurbaran has a realistic manner shown in the picture. It features a room in which an angel is seen at the left kneeling on the land before the Virgin Mary. The figure of Mary is placed between a chair and a little wooden tabular array draped with a green fabric. Mary looks as though she is s urprised to be greeted by the angel although glancing at the floor. She disregards the unfastened Bible since she has been distracted. Behind and above the two figures are cherubs resting on beds of clouds merrily staring down at Mary with eyes from Heaven. Elementss such as visible radiation, colour, and texture are used in The Annunciation. Francisco de Zubaran does non demo a beginning of visible radiation in the picture, but we can see the light get downing from heaven with the cherubs and bit by bit gets darker to where the image about looks blurry on the lower left following to the angel. Light besides emphasizes the just tegument of the Angel and Mary as they both look down towards a shady floor. It reflects the unfastened Bible hinting on the sanctity and importance of Mary. Color draws attending to of import characters and objects in the picture. The ruddy and bluish Mary wears gives us a sense she is the chief focal point of the image since they are two different colourss in temperature and really concentrated. The bright yellow used indicates a celestial felicity or spirit such as how the dove is painted. The little soft silky texture used in this picture shows Zurbaran ‘s usage of pragmatism. The curtain looks about perfect compared to the remainder of the room. If the picture is looked at closely, you can see more symbolism such as a really weak xanthous visible radiation around Mary ‘s caput about like a aura which signifies her sanctity. The little xanthous dove at the top of the picture besides looks down at Mary and even gives a visible radiation pointed down at her caput. The cherubs and the angel are all smiling giving the image a joyful significance. You can besides see the flowers at the bottom right giving the painting an even more sense of softness, raising, and peace. The iconography of The Annunciation is shown how Zurbaran portrays the narrative of the Angel Gabriel looking earlier Mary to denote that God has chosen her to bare a boy, Jesus, who will salvage God ‘s people from their wickednesss. An anon. individual explains â€Å" Zurbaran besides idealizes Mary to stress her sanctity. Mary maintains a graceful airs even when she is frightened by the Angel ‘s intelligence. The room is besides au naturel and suggests Mary ‘s modestness. The Angel appears soft and the white colour of the angel shows the pureness of God ‘s courier. † Today, The Annunciation corsets at the Philadelphia Museum of Art as Francisco de Zurbaran continues to delight many with his endowments with the elements used in such an of import spiritual event. You can state he take to paint spiritual bible narratives with his really precise manner of painting the significance, symbolism, and great item.

Twelfth Night Essays (966 words) - Orsino, Olivia, Viola

Twelfth Night In Shakespeare's "Twelfth Night", it is clearly evident that the fluctuation in attitude to the dual role and situation and tribulations imposed upon the character of Viola/Cesario ends up in a better understanding of both sexes, and thus, allows Viola to have a better understanding for Orsino. Near the opening of the play, when Viola is adopting her male identity, she creates another self, like two masks and may decide to wear one or the other while swinging between the two dentities in emotion and in character. She decides to take on this identity because she has more freedom in society in her Cesario mask, which is evident when she is readily accepted by Orsino, whereas, in her female identity she would not be. Thus, a customary role in society and to the outlooks of others is portrayed. Orsino sees Cesario, as a young squire just starting out in the world, much like himself as a young, spry lad, so he has a tendency to be more willing to unload onto her with his troubles and sorr ows, seeking a companion with which to share and to teach. Thus, Viola grows in her male disguise to get a better feeling for his inner self, not the self that heshows to the public, or would reveal and share with Viola in her true female self, but rather his secret self, as he believes he shares with a peer. So, she grows to love him. But, Orsino's motivation is actually not love for Viola, but rather he seems to be in love with love itself. His entire world is filled with love but he knows that there might be a turning point for him, like when he says: If music be the food of love, play on; give me excess of it, that, surfeiting, the appetite may sicken, and so die. (206) This quote shows that he knows that he is so caught up in "love", that he hopes his appetite for love may simmer when he takes more than he can handle. Near the end of the play, when all tricks and treacheries are revealed and all masks are lifted, Orsino "falls" in love with Viola. He first forgives her/him of her/his duty to him, the master; then says that she shall now be her master's mistress: Your master quits you; and for your service done him, so much against the mettle of your sex, so far beneath your soft and tender breeding, and since you call'd me master for so long, here is my hand. You shall from this time be your master's mistress (237) This is sort of a switching love as he thought he was in love with Olivia in the beginning, but, he readily switches his love to Viola, as he feel she knows her personality well. As for Viola, she declares her love for Orsino many times, as if by saying that she would love him if she were a lady. When Orsino first sends Cesario to act as a messenger and send Orsino's love to Olivia, Cesario proclaims: I'll do my best to woo your lady; [aside] yet, a barful strife! Whoe'er I woo, myself would be his wife. (210) This shows that Viola knows what a difficult situation that she is in, and that she might try to woo her out of loving Orsino, so that she might have him for herself; except there is a slight, unexpected twist of fate...After Cesario leaves from Olivia's, she declares: yet my state is well; I am a gentleman." I'll be sworn thou art. Thy tongue, thy face, thy limbs, and spirit, do give thee five-fold blazon. Not too fast: soft, soft! Unless the master were the man. How now! Even so quickly may one catch the plague? Methinks I feel this youth's per- fections with an invisible and subtle stealth to creep in at mine eyes. Well, let it be. What ho, Malvolio! (212) Olivia, is thinking back to her question to Cesario, and his response to it. Then she replies to Cesario's response, to herself, thinking about him. She agrees with his response, then goes over his many delightfulfeatures, and wonders how she so quickly has caught the plague of love for young Cesario. She decides that it is her feeling towards

Marcus Crassus essays

Marcus Crassus essays In the Roman era there were many great noble men but one in particular stands out named Marcus Licinius Crassus. He rose to power quickly and became the wealthiest man in Rome. He became colleagues with Caesar and Pompey and helped them achieve the high status that they had. He did not have a good childhood and came from a poor family. This mad the wealth and prestige that he gained that much more respectable. Crassus was born about 115 B.C., in Rome. He had an older and a younger brother who were both married and lived with them and his parents in a small house in Rome. He was educated out of his house by his parents. His father married a woman whom was from a well to do family. His father was born into the office of a censor and was given great honor. In battle his father perished along with his older brother. From this happening Crassus inherited his fathers money and ended up marrying his brothers widow named Licinia. He ended up staying with her till death and together they had many children. Some of the ways that he went about getting his money were sneaky yet smart. He took notice to how close and tall the houses in Rome were and that they would be easily susceptible to fire. Rome also had no public fire brigades. He formed the first fire brigade from his host of slaves that he owned. His idea was to set fire to houses then buy those houses from the owners. The owners would sell the houses cheaply because they were on fire and were no use to them anymore. By doing this he soon owned a majority of Roman land. He also bought many slaves who were architects and builders. He had them rebuild the burned down houses. Crassus never built one house other than his own. Even though Crassus owned many silver mines, land, and had other workers to work on them, he valued his slaves the most. He owned over five hundred slaves and all different talents. They were excellent readers, silversmiths, table-waiters, ...

The Chemistry of Cyanide Poisoning and Why it Kills

The Chemistry of Cyanide Poisoning and Why it Kills Murder mysteries and spy novels often feature cyanide as a fast-acting poison, but you can be exposed to this toxin from everyday chemicals and even common foods. Have you ever wondered how cyanide poisons and kills people, how much it takes before its toxic, and whether there is a cure? Heres what you need to know. What Is Cyanide? The term cyanide refers to any chemical containing a carbon-nitrogen (CN) bond. Many substances contain cyanide, but not all of them are deadly poisons. Sodium cyanide (NaCN), potassium cyanide (KCN), hydrogen cyanide (HCN), and cyanogen chloride (CNCl) are lethal, but thousands of compounds called nitriles contain the cyanide group yet arent as toxic. In fact, you can find cyanide in nitriles used as pharmaceuticals, such as  citalopram (Celexa) and  cimetidine (Tagamet). Nitriles arent as dangerous because they dont readily release the CN- ion, which is the group that acts as a metabolic poison. How Cyanide Poisons In a nutshell, cyanide prevents cells from using oxygen to make energy molecules. The cyanide ion, CN-, binds to the iron atom in cytochrome C oxidase in the mitochondria of cells. It acts as an irreversible enzyme inhibitor, preventing cytochrome C oxidase from doing its job, which is to transport electrons to oxygen in the electron transport chain of aerobic cellular respiration. Without the ability to use oxygen, mitochondria cant produce the energy carrier adenosine triphosphate (ATP). Tissues that require this form of energy, such as heart muscle cells and nerve cells, quickly expend all their energy and start to die. When a large enough number of critical cells die, you die. Exposure to Cyanide Cyanide can be used as a poison or chemical warfare agent, but most people are exposed to it unintentionally. Some ways to be exposed to cyanide include: Eating  cassava, lima beans, yucca, bamboo shoots, sorghum,  or almondsEating apple seeds, cherry stones, apricot pits, or peach pitsSmoking cigarettesBurning plasticBurning coalInhaling smoke from a house fireIngesting  acetonitrile-based products are used to remove artificial nailsDrinking water, eating food, touching soil, or inhaling air that has been contaminatedExposure to rodenticide or other cyanide-containing pesticides Cyanide in fruits and vegetables is in the form of cyanogenic glycosides (cyanoglycosides). Sugars attach to these compounds through the process of glycosylation, forming free hydrogen cyanide. Many industrial processes involve compounds that contain cyanide or can react with water or air to produce it. Paper, textile, photochemical, plastics, mining, and metallurgy industries all may deal with cyanide. Some people report an odor of bitter almonds associated with cyanide, but not all toxic compounds produce the scent and not all people can smell it. Cyanide gas is less dense than air, so it will rise. Symptoms of Cyanide Poisoning Inhaling a high dose of cyanide gas rapidly causes unconsciousness and often death. Lower doses may be survivable, especially if immediate aid is provided. The symptoms of cyanide poisoning are similar to those displayed by other conditions or exposure to any of a number of chemicals, so dont assume cyanide is the cause. In any event, do remove yourself from the cause of exposure and seek immediate medical attention. Immediate Symptoms HeadacheDizzinessWeaknessConfusionFatigueLack of coordination Symptoms From Larger Doses or Longer Exposure Low blood pressureUnconsciousnessConvulsionsSlow heart rateLung damageRespiratory failureComa Death from poisoning usually results from respiratory or heart failure. A person exposed to cyanide may have cherry-red skin from high oxygen levels or a dark or blue coloring, from Prussian blue (iron binding to the cyanide ion). Also, skin and body fluids may give off an odor of almonds. How Much Cyanide Is Lethal? How much cyanide is too much depends on the route of exposure, the dose, and duration of exposure. Inhaled cyanide presents a greater risk than ingested cyanide. Skin contact is not as much of a concern (unless the cyanide has been mixed with DMSO), except touching the compound could lead to accidentally swallowing some of it. As a rough estimate, since lethal dose depends on the exact compound and several other factors, about half a gram of ingested cyanide will kill a 160-pound  adult. Unconsciousness, followed by death, could occur within several seconds of inhaling a high dose of cyanide, but lower doses and ingested cyanide may allow a few hours to a couple of days for treatment. Emergency medical attention is critical. Is there a Treatment for Cyanide Poisoning? Because its a relatively common toxin in the environment, the body can detoxify a small amount of cyanide. For example, you can eat the seeds of an apple or withstand cyanide from cigarette smoke without dying. When cyanide is used as a poison or a chemical weapon, treatment depends on the dose. A high dose of inhaled cyanide is lethal too quickly for any treatment to take effect. Initial first aid for inhaled cyanide requires getting the victim to fresh air. Ingested cyanide or lower doses of inhaled cyanide may be countered by administering antidotes that detoxify cyanide or bind to it. For example, natural vitamin B12,  hydroxocobalamin, reacts with cyanide to form  cyanocobalamin, which is excreted in urine. Inhalation of amyl nitrite may aid breathing in victims of cyanide and also carbon monoxide poisoning, although few first aid kits contain these ampules anymore. Depending on the conditions, complete recovery may be possible, although paralysis, liver damage, kidney damage, and hypothyroidism are possible.

Maritime law Coursework Example | Topics and Well Written Essays - 3000 words

Maritime law - Coursework Example That notwithstanding, it is important to also note that an action in tem can only be taken by the plaintiff who has obtained a statutory or maritime lien against the ship and proceedings can only be instituted where a vessel is within/present in the jurisdiction of the state the proceedings are taking place (Bluesteinlawoffice.com, n.d.). Some of the advantages of proceeding in rem include: first the vessel is assumed to be the defendant, thus, eliminating the challenges of the owner being present within the jurisdiction. Thus, this allows the proceedings to continue even in the absence of the vessel owner (Okoli, 2010). Secondly, proceedings in rem require no prior notice as long as a vessel is within the jurisdiction by only the claimant taking an oath in a court. Thirdly, proceedings in rem allow a claimant to arrest a ship and continue with proceedings as in personam (Okoli, 2010). Fourthly, if proceedings in rem are successful, a court rule can dictate that the res be disposed and proceeds used to settle claimants, thus, providing a form of guarantee and security to the claimants (Shrikant and Binita, 2014). For admiralty courts to entertain applications for vessel arrests the following conditions must be satisfied: (1) the dispute must involve maritime claim implying that the claim must be connected to shipping; (2) the claimant must prove that the ship in question has connection with the claim; (3) granting of warranty of arrest is unconditional on the claimant to make all disclosures of any material facts during the application for warranty of arrest such no proceedings have been instituted in another country (Woollam, 2010). Thus, having satisfied the conditions above the process of arrest follows the following procedure: The arrest warrant and writ are served the moment the vessel is within the jurisdiction by an officer of the HM Customs who acts on instructions from the Admiralty.

Changing urban conditions Essay Example | Topics and Well Written Essays - 500 words

Changing urban conditions - Essay Example There are many forms of crimes, but before going deep into the type of crimes, the definition must be known as it will serve as the basic understanding of that concept. Basically, crime is associated with the term illegal which means contrary to the law. It does not adhere to the rules as the rules known as laws are set by a nation to protect its citizens and properties. Once violated, the people who committed the crime are punished (Bailey, 2010, p. 4). The existence of laws and crimes occurs together as laws are present to antagonize the crimes and crimes happen whether intentional or not to go against the laws. Crime can also be defined in a more formal way as it is considered as a legal concept. A crime is any punishable act that the society considers as detrimental to its interest. The punishments do not only protect people but also groups and institutions. The acts covered by the concept of crime ranges from traffic violation to homicide, and the violators of the law receive the penalty to protect the society and correct the offenders at the same time (Cassel and Bernstein, 2007, p. 2). Punishments have been used as a form of discipline to get the desired actions for the individuals in the society. Discipline may not seem to be easy to impose on other people as it involves both pleasant and unpleasant to make the people obedient to the laws and authority (Lipsky, 1977, p. 249). The discipline imposed on the offenders is negative or unpleasant as they are secluded from most people and receive different treatment. Some even receive corporal punishment for their crimes committed. Corporal punishment is said to be gruesome as physical pain is applied to the violators or prisoners which can be in the form of electrocuting, whipping and handcuffs. Some states in America forbid the use of such punishments (Palmer, 2010, p. 40). There are many forms of crimes, but the three broad categories are

Mother tongue education Essay Example for Free

Mother tongue education Essay Mercator International Symposium: Europe 2004: A new framework for all languages? The right to mother tongue medium education-the hot potato in human rights instruments Address by Dr. Tove Skutnabb-Kangas in Opening Plenary As long as we have the language, we have the culture. As long as we have the culture, we can hold on to the land. (pg. 1) In an article called Justice for sale. International law favours market values, Mireille DelmasMarty (2003) discusses the danger in the conflict between legal concepts based on, on the one hand, universal market values , on the other hand, genuinely universal non -market values. The genuinely universal non -market values obviously include individual and collective human rights, as a part of the universal common heritage of humanity. Even if philosophy of both human rights law and philosophically oriented parts of political science now start accepting that there shouldbe normative rights in relation to at least some parts of this heritage (in their terminology common public assets), the legal protection of market values is incommensurably stronger than the protection of non-market values. DelmasMarty exemplifies this with the fact that there is no universal international court that individuals could turn to when their (non -market value based) human rights have been violated. Individual rights are entirely a matter for states, and reports are the only form of monitoring (ibid. ). And if this monitoring, which I have exemplified with the Advisory Committee on the Framework Convention, does not support educational linguistic human rights strongly, there is a problem. On the other hand, laws based on market values are being spread by more or less global organizations like the WTO (World Trade Organisation) and, it seems to me, even more dangerously, WIPO (World Intellectual Property Organisation) 25. These laws are being developed extremely rapidly, with harsh sanctions for violations. -(pg. 13) Economist Francois Grin offers through his discussion of market failure in his book about the European Charter for Regional or Minority Languages (2003b) excellent arguments for resisting market dominance for public or common assets/goods like cultural products: â€Å"Even mainstream economics acknowledge that there are some cases where the market is not enough. These cases are called market failure. When there is market failure, the unregulated interplay of supply and demand results in an ina ppropriate level of production of some commodity† (Grin 2003b: 35). In Grins view, many public goods, including minority language protection, are typically under supplied by market forces (ibid. ). The level becomes inappropriately low. Therefore it is the duty of the state(s) to take extra measures to increase it. (pg. 14) Each language reflects a unique world- view and culture complex, mirroring the manner in which a speech community has resolved its problems in dealing with the world, and has formulated its thinking, its system of philosophy and understanding of the world around it. In this, each language is the means of expression of the intangible cultural heritage of people, and it remains a reflection of this culture for some time even after the culture which underlies it decays and crumbles, often under the impact of an intrusive, powerful, usually metropolitan, different culture. However, with the death and disappearance of such a language, an irreplaceable unit in our knowledge and understanding of human thought and world- view is lost forever. (Wurm, ed. 2001: 13). (pg. 17) As long as a numerically small mother tongue does not give you a better job with a higher salary than shifting to a numerically and politically more powerful language, there are, according to thisway of arguing, few arguments to maintain these mother tongues (and bilingualism is often not considered as a real option; the thinking here is often either/or). (pg. 18) I have earlier (Skutnabb -Kangas in press e) claimed that most of these arguments are presented by researchers who tend to write in English and be native speakers of one of the numerically big languages themselves, often English. This does not necessarily mean that they are monolingual themselves, and many of them are global research nomads, holding jobs all over the world, often making the usual rounds in rapid succession, from Britain or USA or Canada to Sydney or Singapore or Hongkong, etc. This means that these researchers have mostly never experienced that their own dominant language has bee n threatened. It seems that many dominant language speakers are much less aware than dominated language speakers of the non -market values of their ownlanguages, and, consequently, of other peoples own languages. At the same time, they are often not aware (or do not want to be aware) of the market benefits that they themselves have access to because of being speakers of dominant languages. Often they take both these benefits and the fact that others are learning their language in a non -reciprocal way, for granted, and are not willing to in any way compensate speakers of dominated languages for these non -earned benefits; they are linguistic free-riders as Philippe van Parijs puts it (2003: 167). This compensation would obviously be fair, even in terms of thetypes of justice that many lawyers accept. Several researchers have started discussing issues in these economic compensation terms (e. g. Grin 2003b, 2004, van Parijs 2003). (pg. 19) Another partially overlapping distinction, also made by Grin (e. g. 2003b: 24-27), can be used to bridge the gap betwe en social market value and non -market value arguments. In describing arguments used to answer the question why anybody, including society as a whole, should bother about maintaining (minority) languages, Grin differentiates between moral considerations arguments and welfare considerations arguments . Most of the legal discourse, including the linguistic human rights considerations, refer to norms about the right tolive in ones own language, even if the extent of the ensuing rights is debated (ibid. : 24- 25). In contrast, the emphasis of the welfare based argument is not on whether something is morally good or bad, but on whether resources are appropriately allocated. The test of an appropriate allocation of resources is whether society is better off as a result of a policy . (pg. 20) Moral or political principles, even if they are sometimes described as human rights, are not necessarily part of internationallaw. They are things that governments should do, if they are nice, not something they must do. Being nice is not a very convincing argument and is less persuasive than rights and freedoms that have the weight of the law behind them. (pg. 20)

Kants Moral Principles Essay -- Kant Immanuel Philosophy Morals Essay

Kant's Moral Principles   Ã‚  Ã‚  Ã‚  Ã‚  In the Foundation of the Metaphysics of Morals, the author, Immanuel Kant, tries to form a base by rejecting all ethical theories that are connected to consequences, and then focusing on our ethical motivations and actions. Kant wants to derive good characters out of contingently right actions. He believes that everything is contingent (everything can have good or bad worth, depending on how it is used). So he is trying to find the supreme principal of morality in all his reasoning. Kant also believes that an action is right or wrong based solely on the reason by which it was performed. However, a Utilitarian, like John Mill, would reject Kant’s reasoning of originating good characters out of actions alone, and instead argue that if an action has bad consequences, then the action was morally wrong.   Ã‚  Ã‚  Ã‚  Ã‚  Kant believes that an action has moral worth only if it is done out of respect for our moral code. He names this moral action a ‘duty.’ Kant also believes that in determining the moral worth of an action, we need to look at the maxim by which it was performed. So, we need to look at one’s reason for doing an action to determine if it is a duty. If the reason for performing the action is justified, then the action is a duty. However, Kant says there are two different types of reasons for performing an action. Kant calls these reasons ‘imperatives.’ The first reason for performing an action, the hypothetical imperative, is based on consequences and on our personal preferences. They are also contingent, meaning that they can be good or bad depending on how they are used. People choose to perform a given action because of the hypothetical imperative. The second reason for performing an action according to Kant is called the categorical imperative. These are not based on our preferences, don’t deal with consequences of an action, and are derived a priori. They are completely separate from hypothetical imperatives. We all have knowledge of categorical imperatives before experiencing them first. They are kind of a second nature for us, which needs to be recognized according to Kant. These are the most important reason for performing an action. These imperatives also have the characteristics that Kant needs in order to make his point that all of our moral principals are categ orical, have absolute authority, and are independent o... ...t hope to predict the outcome of any given situation. It is impossible; there is no such thing as seeing the future. So by making a false promise to your friend, you have still done the morally wrong action, even though it will most likely save them some suffering. It did indeed take away their choices, so they can’t act in a way they want to act (going to class). I happen to agree with Kant’s idea here. I think that no matter what the consequences are, performing the right action is always the right thing to do.   Ã‚  Ã‚  Ã‚  Ã‚  Overall I think that Kant has better arguments because they are directed at the individual, not at society in whole. I also agree that the moral worth of actions is determined by the motivating principal of the action, not by the consequences, like John Mill. So I am a deontologist, for the most part. However, I also agree with some of the things that Mill has to say. So is there a way that we can combine the ideas of Mill and Kant together in order to form a perfect society in which everybody is happy? I don’t know the answer to this question, but we should all strive to do so, and we should start by respecting each other’s autonomy and treating others as ends.

The Kiss: Brancusi and Rodin

Auguste Rodin was a French artist most famous for his sculpting. He was born in 1840 and survived into the Twentieth century, dying in November of 1917.   He possessed and innate ability to sculpt in clay, creating dynamic movement in roughly pock marked human figures with a high degree of realism. His work was not well received initially though he came into vogue rather quickly.He was schooled in a traditional manner on the Ecole de Beaux Arte in Paris but in his work he was in the vanguard of the movement toward modern sculpture (Wikipedia.org Rodin).   Constantin Brancusi was born in Romania in 1876 and died in 1957. His sculptures were simple, reflecting his background as a stonemason in his native land. Having run away from home at an early age to escape the abuse of his father and brothers, he impressed an employer with his carving ability and the man financed his secondary education at a crafts school where he graduated with honors. He then attended the Bucharest School of Fine Arts (Wikipedia.org Brancusi).Brancusi made his way to Paris, the center of the world of art at that time, and made the acquaintance of fellow artists and intellectuals (Franck & Liebow). For two years he labored in the workshop of   Antonin Mercie of the Paris Ecole des Beaux Arte. At that point he was invited to work with the master, Auguste Rodin. Brancusi recognized the genius of Rodin but apparently felt smothered by the essence of the great sculptor and left after a few months. He was quoted as saying that, â€Å"Nothing can grow under big trees,† (Wikipedia.org Brancusi) Rodin was, at his core, a naturalist, and as consumed with the emotion and character he found in the model as he was in faithfully rendering an exact likeness.He also, it was said, believed, more so than other sculptors, that a human’s character is revealed in his physical features. His theory was that every portion of the sculpted work had a part to play in communicating the feeling, po wer and inner strength of the work. The grip of the toes, for instance, in his Thinker, is depicted to show the intensity with which the subject is going about his task. â€Å"What makes my Thinker think is that he thinks not only with his brain, with his knitted brow, his distended nostrils and compressed lips, but with every muscle of his arms, back, and legs, with his clenched fist and gripping toes† (quoted in Wikipedia.org Rodin)   he said.While most of Paris’ sculptors were working in clay and having their work cast in bronze, Brancusi most often labored as a carver and utilized the direct method of creating his sculpture. He removed the superfluous material and was left with his creation. In the case of his original The Kiss, (there are several versions), as the old saw goes, he simple cut off everything that did not look like a pair of kissers. Carved in limestone, it measures 23† x 13  ¾ â€Å" x 10  ¾Ã¢â‚¬ . It is a highly stylized depiction of a man and woman face to face, their arms entwined, their lips pressed together and their bodies touching.The work gives the impression that the two are so engrossed and joined in love and sensuality that they have become one. Rodin’s   version of the same subject is likewise carved directly into stone, in this case, marble, though there exist many replicas of the work in bronze, cast from Rodin’s original carving. The original title was Francesca da Rimini and depicted a scene from Dante’s Inferno. It represents an Italian noblewoman who falls in love with her husband’s younger brother. The couple are nude and embracing, with their lips close, each to the other, but not actually touching, so the kiss is not consummated.Both works by these two contemporary masters, working in the same city, are of the same subject and both are carved directly into stone. Here the similarity between the two ends. Rodin’s powerful style is seen in the work and   t here is no question as to what he means to say. The sensuality of the Rodin work is manifest in the texture of the piece and the rendition of muscle and bone. There is a tension in the work that is palpable. Brancusi’s Kiss is simple and direct. It is highly stylized and cubistic in its conception.There is more than a hint of the primitive in the statue. The two artists chose to handle form in a drastically different manner while addressing the same theme. Rodin’s work and even its original title suggest sensuality, passion and perhaps even outright sin. Brancusi’s Kiss is more suggestive of love than of passion (Art 101). It is static and has no movement to it.   The two humans depicted in Brancusi’s work are bonded as if they are one unit, suggesting a stability and deeper emotional unity than that conveyed by RodinThe two artists have, as would have likely pleased Robert Frost, taken different roads. It is not certain which of the two men chose the o ne less traveled but there are differences that make it obvious that they diverge. As to which is the better work, that is not possible to determine, for art, like much of life, is subjective and largely up to individual taste.But Rodin’s work is more academic and conventional where Brancusi’s work is more primal and addresses a basic emotion in the heart and soul of humanity in perhaps a more direct manner. It is possible to dismiss Brancusi’s work at first glance, saying that a child could have done it, while Rodin’s piece has a realism that would belie such a thought.There are those critics who suggest that the Emperor is indeed nude and the Brancusi work is a joke foisted on the art public much like the attitude many take toward the works of Picasso. Rodin’s work became acceptable after a period of adjustment and the public began to understand what he meant to convey. Brancusi’s work is similar in that aspect, and more acceptable as the public gets past their original assessment. Still, both pieces are from the hand of a master who has chosen his own method of bringing his vision to the world.Works Cited.Franck, D. and Liebow, C.

Additive Manufacturing Technology In Dental Implants Engineering Essay

Medical industry is one of the most existing industries which extensively use Rapid Manufacturing for their application. Every twenty-four hours tonss of people all around the universe faces different medical jobs and they easy get treated really rapidly merely because of new fabrication technique. From this aspect Dental and Hearing industries are in a tendency which is developing really fast to undertake the challenges of future and treated as the most successful portion of this industry. The full research and application are depends on some alone particular functionality, form and cost. Sing all demands the constituent are produced utilizing plentifulness of stuffs through different procedure for both industries such as, This study gives the brief thought about usage of linear fabrication engineering in medical industry particularly in dental and hearing with an illustration of fabricating constituent, it besides put light on advantage for both modeller and user after utilizing linear fabrication engineering. The Rapid Prototyping ( RP ) can be defined as a group of technique which refers to the bed by layer fiction of 3-dimensional ( 3D ) physical theoretical accounts straight from Computer aided design ( CAD ) . ( Cooper, 2001 ) By and large this RP is known as the Additive fabrication ( AM ) procedure, because of recent sweetening and development in the field of Computer Numerical Control ( CNC ) machining has prove this engineering as the portion of RP procedure. ( Wimpenny, ( 2010 ) ) Development in CNC machining which happened as an RP technique include remotion of stuff with higher rates, addition in cutting velocities and besides with higher machine axis speed. New development in both package and 3D bounder informations coped up with the recent alterations. ( Wimpenny, ( 2010 ) ) The procedure begins after making a 3D theoretical account utilizing CAD package and it is indistinguishable for all built techniques. The theoretical account is so convert in to Standard Triangulation Language ( STL ) format, this format shows the 3D surfaces as an assembly of many contriver trigons. At following phase STL file slice the 3D theoretical account in to beds. As we know the linear fabrication is gradual procedure in which parts are industries through beds and each beds are joined and procedure continues until the concluding portion formed. RP ‘s linear nature allows is to make parts with complicated internal characteristics which is non possible by other agencies like hollow countries and undercuts for that these parts some times supports are necessary. ( ( thenar, 1998 ) )2.2.1: Potential benefits of Rapid prototyping:Rapid Prototyping has great advantages in technology, fabrication, selling and buying because it is easy rectified the job before production through design procedure. And it becomes clearer after comparing it with both CNC and traditional methods. ( efunda, 2010 ) Other benefits of rapid prototyping are follows, ( Wimpenny, ( 2010 ) ) Elimination of clip of tooling and cost Complexity does non state about cost and clip. Bespoke/customised parts which are non possible for early methods. Through procedure is really easy to unite parts. It is easy to incorporate parts like mechanical and electronics Need non to piece the portion it will automatically come after procedure. Proper look into up cut down the stock list Easy to machine complex geometries like hollow parts and crisp interior cones.3.0: Rapid Prototyping Technologies:Assortment of rapid prototyping engineering is being used in different country for different prototyping intent. The purpose consider as fabrication of follows, Hearing assistance shell Dental header, coronating and Bridgess3.1: Linear fabrication Technologies:3.1.1: Stereolithography ( SLA ) : Stereolithography ( SLA ) is an linear fabrication engineering for bring forthing paradigms, forms, theoretical accounts, and in some instances, production parts. SLA builds theoretical account of plastic parts individual bed at a clip by following beam of optical maser on the VAT of liquid UV curable exposure polymer rosin. When UV light work stoppages the surface of the polymer rosin solidify the individual bed of rosin, when one bed is completed after following, the built platform descend in deepness by individual bed thickness ( Schmitt, 2005 ) . Then, a rosin filled blade expanses over the cross subdivision and make full it with fresh stuff and so optical maser once more do the same procedure on the top of the old bed, this procedure continues until the theoretical account is produced. Material self adhesive belongings to bond each bed and forma complete 3D theoretical account, after edifice parts are cleaned in dawanol rosin and intoxicant and so cured in a UV oven. ( wikipedia, 2010 ) Stereolithography requires support for some object holding complex geometries like over bents and under cuts to keep the portion in lift platform and to forestall alteration in geometry from non debaring because of gravitation but to keep accurately. Supports are either automatically or manually designed along with the theoretical account, after procedure completion elevates it from VAT and cut off the supports. Then station processing requires which include cleansing and station remedy. ( Schmitt, 2005 ) Fig 1: The stereolithography procedure ( wikipedia, 2010 ) Advantages of Stereo lithography: ( Wimpenny, ( 2010 ) ) High quality surface finish with good mechanical strength Models are clear and sound in declaration Reliable for high productiveness Disadvantages of Stereolithography: Expansive in machines and care every bit compared to others and Complete service in contract and besides require laser replacing. Materials are expensive ( ?120-200/kg ) and in limited scope Should see wellness and safety issues with accessory equipment Wet stuff handling Require station processing 3.1.2: Laser Sintering ( LS ) : â€Å" Laser sintering ( LS ) is an linear fabrication technique by which parts are produces straight from 3D CAD theoretical account built bed by bed similar to SLA but instead than liquid rosin pulverization is used † ( Arptech, 2010 ) . The CO2 Laser beam traces the all right heat fusible pulverization bed to increase its liquescent temperature so that pulverization fuses and organize a solid mass. The optical maser beam energy is maintained merely to blend pulverization in defined country of cross subdivision. The whole chamber temperature is fixed merely below the runing point of pulverization, so laser somewhat increase the temperature for sintering procedure or it means that welding without runing ( Arptech, 2010 ) . For the following measure Piston descend by individual bed thickness to resign topographic point for the new pulverization bed. Roller dispersed powder stuff on the built platform. This procedure continues until the sold theoretical account is produced with blending each bed below it. Then parts removed from the platform and left pulverization is removed for farther usage, produced portion may necessitate station processing for good surface coating such as sanding, it depend on the application. Complex geometries like overhangs and under cuts are supported by the solid pulverization bed. ( Schmitt, Rapid prototyping in dental medicine: engineering and application, 2005 ) Advantages of LS: ( Wimpenny, ( 2010 ) ) Potential stuffs are available in broad scope for processing Properties of the produced portion are really near to technology criterions With out station hardening theoretical accounts are used Fresh pulverization Acts of the Apostless as the support No demand to plan supports Easy to take support stuff Support stuff can be partly ( 30 % ) reused = less waste Supports are wholly removed with out feeling Partss are stacked on the top and inside the another object Disadvantages of LS: Process get shrink so need to give compensation Difficult procedure as compared to SLA Partss are porous require excess care/ powdery surface Build orientation defines the belongingss Brittle parts as compared to others Dust control is a large job in this procedure Fig 2: Laser sintering procedure plants ( Arptech, 2010 ) 3.1.3: Fused Deposition Modeling ( FDM ) : â€Å" Construction of 3D theoretical accounts through the uninterrupted deposition of an extruded fibril of stuff † ( Wimpenny, ( 2010 ) ) FDM is largely known as a 2nd best prototyping engineering after SLA ( Additive3d, 2010 ) ; it consists of temperature governable caput which extrude bed by bed thermo fictile stuff. Material is supplied to an bulge nose through a plastic fibril which is non wounded on a spiral. Heated nozzle melt the plastic in to semi liquid province and it besides has a mechanism through which it pour the liquid province plastic when it required agencies on and off system. Nozzle is allowed to travel in both perpendicular and horizontal waies and it is set on a mechanical phase. As the nozzle base on balls through the tabular array it pour the liquid province fictile stuff in the needed flight bed by bed. The fictile rapidly solidify and bonded with the old bed after chuck outing from the nose. The whole system is hold in a chamber which is maintained at a temperature somewhat lower so the runing point of plastic. Assortment of patterning colourss and stuffs are available in FDM procedure such as investing casting wax and medical class ABS. ( Schmitt, Rapid prototyping in dental medicine: engineering and application, 2005 ) Fig 3: Fused deposition patterning procedure ( express.redeyeondemand, 2010 ) Advantages of FDM: ( Wimpenny, ( 2010 ) ) Operation is simple Machines are inexpensive and dependable as compared to others Assortment of stuffs can be used for functional paradigms Easy to run in office environment. Disadvantages of FDM: Slow in procedure Partss are porous so they require excess attention Build orientation set the belongingss otherwise delamination can happen Support stuff should be removed otherwise it modify the physique stuff which are manually broken Waste of support stuff3.1.4: 3D Printing:â€Å" 3D printingA uses standard inkjet publishing engineering to make parts layer by bed by lodging a liquid binder onto thin beds of pulverization. Alternatively of feeding paper under the print caputs like a 2D pressman † ( Materialise, 2010 ) , in 3D printing procedure print caput prints the portion cross subdivision informations after go throughing over a bed of pulverization. Feed Piston and platform are mechanized to administer pulverization in full physique platform equally and accurately, which comes up bit by bit for every individual bed. Powder which is distributed from feed Piston is spread on a build platform through roller mechanism. After distributing the pulverization bed, Printing starts with inkjet print caput to the cross subdivision of the first bed or the base of the theoretical account on the all right bed of pulverization, with pasting the pulverization together. After this Piston fall the platform by individual bed thickness of 0.1mm and fresh bed of pulverization is distributed equally on the top of earlier 1. The print head start publishing new bed after using informations for the following cross subdivision, and it besides glued automatically with the old 1. This procedure repeated it self for every individual bed until the solid theoretical account is produced ( Materialise, 2010 ) . After finishing the procedure, The reinforced chamber and parts are supported by left pulverization. Partss are removed from the build chamber after stuff get set, feed platform usage staying loose pulverization for farther production. Fig 4: 3D Inkjet printing procedure ( Rapid prototyping centre, 2010 ) Advantages of 3D printing: Less fabrication cost for little and medium parts Good surface coating can be achieved through station processing and sanding Partss are reused after painting and smoothing Disadvantages of 3D printing: 3DP parts have small unsmooth visual aspect because of fictile bead layering Not good for big portion because slow in procedure 3.1.5: Jetting ( PolyJet from Objet ) : Jeting is significantly similar to stereolithography in engineering with lone difference that it uses solid province exposure sensitive stuff. PolyJet engineering works on the jetting procedure in which exposure polymer stuffs are jetted on a built platform in extremist thin beds to finish portion bed by bed. Ultra violet visible radiation remedies every individual exposure polymer stuff bed instantly after gushing, with out station hardening theoretical accounts are to the full cured on managing and can be used instantly. The supports which are designed to back up complex geometries are really easy to take by manus or H2O jetting because it is gel like support stuff. ( Materialise, 2010 ) Fig 5: Ployjet printing procedure ( Art corporation, 2010 )3.1.6: Multi jet Mold:Multi Jet Modeling is a fast rapid prototyping engineering besides footings as Thermo jet and is used for construct mold. The theoretical accounts truth is less every bit compared to stereolithography because of wax like plastic theoretical accounts. â€Å" The procedure uses a print caput that consists of additive arranged jets which spray bantam droplets of liquid liquid stuff which cool and harden on impact to organize the solid object † . ( ( About.com, 2010 ) ) Fig 6: multi jet patterning procedure ( Wimpenny. D. ( 2010 ) . RP & A ; CNC machining, Rapid Product Development, De Montfort University, Leicester ) Advantages of Multi jet mold: ( Cooper, 2001 ) Cost effectual Reliable Good surface finish and net working capableness Disadvantages of Multi jet mold: Materials are low in strength Relatively high cost for edifice stuffs Partss of support stuffs are unsmooth in surface3.2: Materials:Linear fabrication procedure requires different stuffs for different single application. Materials vary harmonizing to company and there machines. For Dental and Hearing parts the stuffs are suited such as, Perfactory- envisiontec e-shell 200- Rigid and Durable DMLS- Titanium and Cobalt crome 3D- Castable stuffs Solidscape D66+ 3D printer- Non toxic thermoplastic stuff Projet MP300- Visijet MP200 Dental theoretical account stuff Objet Eden machines- Full remedy rose and skin tone4.0: Application in Dental and Hearing industries:Hearing assistance shells Dental implants4.0.1: Hearing assistance shell machines:A: â€Å" LS are a free signifier fiction procedure using linear rapid fabrication engineering. The optical maser sintering engineering was developed at the University of Texas, originally licensed to DTM Corporation † . ( Paramount, 2010 ) Laser sintering has become the fabricating method of pick in the hearing assistance industry. This industry has to strongly necessitate to custom-make its merchandises, because the success of this procedure is to the full depend on the ability of portion to accommodate to the anatomy of the audile canal. The fabrication procedure does non depend on figure of indistinguishable or single merchandise and it ever runs with the same efficiency. The entire reinforced country of optical maser sintering system can be filled with several hundred hearing assistance shells and therefore all merchandises can bring forth in one dark. In this procedure optical maser copy the anatomy by making wax form so copied wax form scanned to make a 3D informations and apart from geometry every portion is integrate with certain designation figure so that that it can be easy identified after procedure. Laser sinter the shell and it will unite through electronic constituent. Presently this optical maser sinteri ng engineering produces about 100000 hearing assistance shells in a twelvemonth and it can be achieved through one individual plastic optical maser sintering machine ( Stotko, 2005 ) Fig 7: Laser sintered hearing assistance ( Stotko, 2005 ) Bacillus: Objet ‘s solution is the hearing assistance industry which done all necessary trial to guarantee that that the stuffs which are developed for hearing assistance instruments are suited for the procedure every bit good as Oklahoma from medical point of position. Objet ‘s Eden machines are work on Ployjet engineering and industry hearing AIDSs with perfect coating and good quality sing more flexibleness, productiveness and less cost. The solution including three material picks for alone hearing assistance instrument like clear, rose clear, skin tone. Machines particular rosin replacing system makes it easy to alter the rosin for the peculiar merchandise. Eden machines produce merchandise with really thin 16 micrometer bed thickness which are good in all facet for hearing industry. ( Objet, 2010 ) Fig 8: Objet hearing AIDSs for different stuffs ( Objet, 2010 ) Degree centigrades: Prefactory enhanced the hearing assistance shell sing both cost and clip. It besides offers the perfectness for the hearing assistance industry with over several medically approved stuff to offer with assorted skin tone colourss stuffs along with ruddy, bluish, tap, tan, mocca, ecru, chocolate, brown, black, white, rose clear and crystal clear it is new launched soft stuff. It is integrated on a face home base for application get downing from single hears casts to the concluding shells. ( envisionTec, 2010 ) Fig 9: Hearing assistance envision TEC e-Shell 200 series ( envisionTec, 2010 ) Through Perfactory 30 shells are produced at every 90 proceedingss which is more than earlier procedure because of its flexibleness in bring forthing parts with easy stuff changing. † EnvisionTEC e-Shell 200 is a liquid, photo-reactive propenoate for constructing functional parts which are tough, opaque, water- and perspiration-resistant † , and available in several different tegument tone colourss. ( envisionTec, 2010 ) 4.0.2: Dental Implants: Two chief paths ; 1: Investing casting from AM forms 2: Direct metal parts by optical maser sintering/melting4.0.2.1: Investing casting:Several machines capable of doing forms A: The Solidscape D66+ 3D pressman produce high precised wax form from 3D CAD information. This produces waxups utilizing linear engineering which is known as bead on demand jetting. The Non toxic thermoplastic stuff through which waxups produced are to the full castable and could non go forth any residuary ashes which create job for farther procedure. The whole procedure is clear in border and spreads because of negligible shrinking of the stuff and it besides remain consistent for every tally. ( Bruce Lusting, 2010 ) The D 66+ , which is an entryway to the new Prexacto merchandise line, is focused for bring forthing high quality wax forms for coronating and get bying and for other dental parts in little dental research labs. If it is used satisfactorily so the parts are produced at low cost with high degree of client satisfaction and it ‘s of import for proper digital dental medicine flow. The Solidscape Prexacto is the perfect merchandise line sing both monetary value and public presentation for dental research labs. ( CAD BLU DENTAL, 2010 ) D66+ produced 750 units per month with low norm cost so the earlier one and it besides saves more than $ 12,000 per month over traditional methods. ( Bruce Lusting, 2010 ) Fig 10: Solidscape D66+ pressman ( CAD BLU DENTAL, 2010 ) Bacillus: For dental procedure the Envisiontec perfactory Digital Dental Printer ( Perfactory DDP ) is a really good machine for bring forthing dental parts. The capableness of machine is that it can fabricate 65 anatomical wax get bying or units with good declaration of 35 micrometers in less than two hours utilizing wax based polymer system and besides it can bring forth parts with accurate spread systematically.

Babe Ruth essays

Babe Ruth essays Babe Ruth is one of the most influential sports athletes in history. He overcame many obstacles in his life, like a bad childhood, people not believing in him, and his parents and grandparents dying, to get to where he is now. Not only did his childhood deprive him of being influenced by his parents but with his grandparents also. You see his parents died when he was young. Soon after that his grandparents died. After his grandparents died foster family took custody of him but sent him to a boarding school and there he got 2 wholesome meals a day and was around people that cared about him 24 hours a day. Despite of his childhood he still became very famous. Even though his parents died when he was young he was still able to learn baseball from a role model they called brother Mathias who was a member of the clergy. Soon this role model saw that Ruth was getting way too good at baseball for the coaches at his boarding school so they sent him to another boarding school where some of the states best coaches were at. Since he became so famous after his bad childhood he showed people that you must keep following your dreams if you want to reach them. Even though he suffered many deaths through his childhood he still gave 100% effort all the time. When he told his friends that he wanted to be a baseball player when he grew up they all mostly laughed at him but he knew one day that he would get there. Not only does this inspirational story prove he was very confident in himself but that he is one of the most influential sports athletes in history. Without his ongoing struggle to live a happy and easy life this accomplishment might not have been so great. ...

Woodrow Wilson 28th President of the United States Woodrow Wilsons Childhood and Education: Born on December 28, 1856 in Staunton, Virginia, Thomas Woodrow Wilson soon moved to Augusta, Georgia. He was taught at home. In 1873, he went to Davidson College but soon dropped out due to health issues. He entered the College of New Jersey which is now called Princeton in 1875. He graduated in 1879. Wilson studied law and was admitted to the bar in 1882. He soon decided to go back to school and become an educator. He earned a Ph.D. in Political Science from Johns Hopkins University. Family Ties: Wilson was the son of Joseph Ruggles Wilson, a Presbyterian Minister, and Janet Jessie Woodrow Wilson. He had two sisters and one brother. On June 23, 1885, Wilson married Ellen Louis Axson, the daughter of a Presbyterian minister. She died in the White House while Wilson was president on August 6, 1914. On December 18, 1915, Wilson would remarry Edith Bolling Galt  at her home while he was still president. Wilson had three daughters by his first marriage: Margaret Woodrow Wilson, Jessie Woodrow Wilson, and Eleanor Randolph Wilson. Woodrow Wilsons Career Before the Presidency: Wilson served as a professor at Bryn Mawr College from 1885-88 and then as professor of history at Wesleyan University from 1888-90. He then became a professor of political economy at Princeton. In 1902, he was appointed President of Princeton University serving until 1910. Then in 1911, Wilson was elected as the Governor of New Jersey. He served until 1913 when he became president. Becoming the President - 1912: Wilson desired to be nominated for the presidency and campaigned for the nomination. He was nominated by the Democratic Party with Thomas Marshall as his vice president. He was opposed not only by incumbent President William Taft but also by Bull Moose candidate Theodore Roosevelt. The Republican Party was divided between Taft and Roosevelt which meant that Wilson easily won the presidency with 42% of the vote. Roosevelt had received 27% and Taft and won 23%. Election of 1916: Wilson was renominated to run for the presidency in 1916 on the first ballot along with Marshall as his Vice President. He was opposed by Republican Charles Evans Hughes. At the time of the election, Europe was at war. The Democrats used the slogan, He kept us out of war, as they campaigned for Wilson. There was much support, however, for his opponent and Wilson won in a close election with 277 out of 534 electoral votes. Events and Accomplishments of Woodrow Wilson’s Presidency: One of the first events of Wilsons presidency was the passage of the Underwood Tariff. This reduced tariff rates from 41 to 27%. It also created the first federal income tax after the passage of the 16th Amendment. In 1913, the Federal Reserve Act created the Federal Reserve system to help deal with economic highs and lows. It provided banks with loans and helped smooth out business cycles. In 1914, the Clayton Anti-Trust Act was passed to help labor have more rights. It allowed important labor tools like strikes, pickets, and boycotts. During this time, a revolution was occurring in Mexico. In 1914, Venustiano Carranza took over the Mexican government. However, Pancho Villa held much of northern Mexico. When Villa crossed into America in 1916 and killed 17 Americans, Wilson sent 6,000 troops under General John Pershing to the area. Pershing pursued Villa into Mexico upsetting the Mexican government and Carranza. World War I began in 1914 when Archduke Francis Ferdinand was assassinated by a Serbian nationalist. Due to agreements made among  the European nations, many eventually joined the war. The Central Powers: Germany, Austria-Hungary, Turkey, and Bulgaria fought against the Allies: Britain, France, Russia, Italy, Japan, Portugal, China, and Greece. America remained neutral at first but eventually entered the war in 1917 on the side of the allies. Two reasons were the sinking of the British ship Lusitania which killed 120 Americans and the Zimmerman telegram which revealed that Germany was trying to get an agreement with Mexico to form an alliance if the U.S. entered the war. America officially entered the war on April 6, 1917. Pershing led American troops into battle helping to defeat the Central Powers. An armistice was signed on November 11, 1918. The Treaty of Versailles signed in 1919 blamed the war on Germany and demanded huge reparations. It also created a League of Nations. In the end, the Senate would not ratify the treaty and would never join the League. Post-Presidential Period: In 1921, Wilson retired in Washington, D.C. He was very sickly. On February 3, 1924, he died of complications from a stroke. Historical Significance: Woodrow Wilson played a huge role in determining if and when America would get involved in World War I. He was an isolationist at heart who attempted to keep America out of war. However, with the Lusitania, the continued harassment of American ships by German submarines, and the release of the Zimmerman Telegram, America would not be held back. Wilson fought for the League of Nations to help avert another World War which won him the 1919 Nobel Peace Prize.

In the instructions Essay Example | Topics and Well Written Essays - 500 words

In the instructions - Essay Example This practice was sustained and the Babylonians in 1750 BC invented a method where the trader would borrow assets to financially support his cargo of merchandises (Tramposh 1991). He gave the lender an extra amount of cash and in trade for this extra amount, the lender authorized the invalidation of the loan should the cargo be damaged, embezzled, or lost. According to Tramposh (1991), this practice was documented roughly 1750 BC in the Code of Hammurabi. Prior to the early 20th century, worker’s compensation remained absent in the United States. At the moment, most individuals provided labor or services. However, for people who did not, in the initial period of the industrial revolution, when a laborer was harmed in the workplace, the issue had to be pursued through the web of legal courts. Injured laborers usually fail in these cases (Lencsis 1998). Most businesses or organizations were much better prepared or knowledgeable than their injured workers in manipulating the courts. Because of this it became apparent that workers should have some level of security from the trouble of injuries or damages on the job. In Indiana, the current worker’s compensation system is obligatory, implying that companies are obliged to give worker’s compensation insurance for their workers. Complete healthcare benefits are given to workers eligible for worker’s compensation benefits (Schoening 2003). Compensations are given for temporary total disability (TTD) and permanent total disability (PTD) in a sum decided by a fraction of the employee’s earnings. Compensation may be accessible for permanent disfigurement which incapacitates the potential worth of prospects of the worker. Occupational and physical treatment compensations are accessible. Death benefits are allocated to a worker’s living spouse or children, founded on a fraction of the worker’s salaries

Project management Essay Example | Topics and Well Written Essays - 1500 words - 2

Project management - Essay Example That is the task of advertising. In order to expand sales and gain profit companies have use advertisement through various means of communication. This economic activity helps to spread the message across the target market for goods or services of the business. At the same time, though advertising can be said to be an element of public relations activities, advertising itself does not always mean public relations. The two concepts, though have much in common, contain many differences as well. Public Relations work for the improvement of company’s image, building public awareness about the company and its activities, as well as effective promotion of certain offers of the company or outstanding features of a product or service. So, public relations refers to â€Å"strategic communication that different types of organizations use for establishing and maintaining symbiotic relationships with relevant publics† (Sriramesh, 2009, p. xxxi). As for advertising, it is currently defined as a communication tool â€Å"directed towards specific target customers in order to carry the message regarding a particular product, service or ideas, meaningfully and persuasively with a view to achieve certain specific objectives such as, to establish brand loyalty, expansion of the existing markets, increased sales volume, etc.† (Kumar & Mittal, 2002, p. 2). ... The country has been admitted to the World Trade Organization (Walters & Samiee, 2003) and, therefore, became an attractive market for many multinational corporations. While the effect of media is suspect of influencing the relationships of different individuals, the targeting of commercial advertising and PR activities toward consumers and strategies employed in order to reach Chinese audience is the primary focus in this study. The fact that media outlets became so widespread in Chinese society serves as the impetus for studying in a more narrow scope the relationship between commercial advertising and PR, and the viewer/consumer in media commercial programming. In addition, the given work aims at analyzing techniques and strategies of advertising agencies used to influence Chinese consumers. Research questions Though Chinese market can be considered relatively new for western companies, it does not experience any lack of attention and is already flooded with foreign companies and, as a result, advertising and PR. However, thought the market is attractive, it has certain peculiarities and unique characteristics that should be considered by entering businesses when trying to become popular in China. Therefore, the given research is trying to clarify the following aspects of public relations and advertising in China: How in particular and to what extent public relations in China differs from advertising and what particular signs make a difference between the two communication activities in the Chinese market. What major communication means, tools and techniques Chinese and multinational companies use in China to effectively deliver the message to the target audience and how effective particular strategies and techniques are.

Future of Tourism in Oman Essay Example | Topics and Well Written Essays - 1500 words

Future of Tourism in Oman - Essay Example There are many difficulties in the development of this industry, because the locals do not want to exceed the limits of a local tourism promotion and thus they are prevented from a global expansion. Tourism in Oman Oman has many different privileges. First of all, this country makes large investments in ecotourism and first class tourism and tourism in this country can be interested for both Western and Eastern tourists. Oman can assure tourists of the absence of corruption and there are many perspectives for business development in this country. Oman is opening its doors for tourists†¦ The spectators are so much attracted by the new territories and numerous sightseeing that the pleasure of exploring this country transfers the borders of traditional tourism. There is no doubt that Arab hospitality is legendary. People from those countries are full of hospitality and there is no doubt that the Westerners will be greatly impressed by a large number of attractions in this country. There are two million inhabitants in Oman and this is an independent state of the Arab world. Tourists are mainly attracted by â€Å"vast coastline, over a thousand miles long, stretching from the Strait of Hormuz in the Persian Gulf to the Yemeni border in the south† (The Seven Stars of the Gulf; Oman: Traditional Terraced Village Scubadiving off the Coast of Fujairah, 2009). Moreover, there are deep historic roots in this country. The Oman museum in Muscat is rather attractive for tourists and there is no doubt that people in this country are proud of their legendary heroes, such as Sindbad the Sailor, for example. There is an evident harmony between the ancient port of Muscat and modernization of this port nowadays. A feeling of cleanness and safety is everywhere. There are different perceptions of the northern and the southern frontiers of Oman. Thus, tourist from different countries can find the places to live and to visit with respect to their own interests (Martin, 200 5). Nevertheless, it should be noted that the most explored part of Oman, which is favorable for tourists is Salalah. Tourist agencies are attracting new tourists speculating on the following things: â€Å"waters are inviting, the sand the softest and silkiest, and the birdlife extraordinary, a visitor's guide cautions you against wandering away "while wearing a sea dress" (Beirman, 2003). Oman provides tourists with different opportunities of having rest. There is an essential technological impact exerted on Oman and the Western tourists can exert a serious negative impact on cultural, moral and social values in Oman (Richards, 1999). On the one hand, in the modern global world such issues as traditional clothes or color of hair can be different even among Omani people. In their hearts and souls these people are religious and they do not have any intention to change their religion or culture. There are many difficulties for Oman and its ability to adapt social and cultural changes with respect to the Western traditions and customs. With this respect, it can be claimed that countries around the world are interested in promotion and support of their interests. In case the residents of one country want to get acquainted with the values of people and nations from another country, there is no doubt that the former should be tolerant to another country and preserve historic uniqueness and dignity of another nation. There is a high cultural

Simplified Soft Decision Decoding of LDPC codes

Simplified Soft Decision Decoding of LDPC codes MARUTHI L N K S GURUMURTHY Abstract LDPC codes gained importance since its re-discovery by Mackay and Neil based on Tanner Graph. This paper presents the implementation of forward error correction soft-input, soft-output decoding process that efficiently decodes the received set of data under low signal-to-noise ratios due to which the errors are reduced and hence transmission time is greatly reduced. The implemented algorithm is less complex and does not require knowledge of signal-to-noise-ratio of the received data-path. INTRODUCTION Error correction coding techniques came into existence after existence of channel capacity theorem by Shannon, the father of information theory in 1948 on reliable communication over noisy transmission channels. Thereafter, many coding techniques were developed for efficient coding techniques, like Hamming, Golay and many other techniques were developed. Though Gallagher in 1962 developed LDPC codes, the method employed was not optimal. Hence it was not reviewed for last 3 decades, until 1992, when a paper â€Å"Near Shannon limit error correcting coding and decoding: turbo codes† presented by Berrou, Glavieux and Thitimajshima changed the trend followed by researchers for the past 5 decades. And now, we are aiming to develop such codes through another strategy. The coding gain provided by this method is much higher when compared to other coding systems. The LDPC codes are becoming more popular because of their reduced power for transmission and less complex logic to achieve l ow BER’s which is very essential for reliable transmission over noisy channels. LDPC CODES Low Density Parity Check (LDPC) codes are a powerful class of forward error correction codes developed by Gallagher in 1962, practically implemented by MacKay in 1995. Low Density refers to less number of 1’s in the Parity Check Matrix (H) of Block Codes. Block codes are a type of Error Correction Codes which uses a Generator Matrix(G) to produces a Code-word of length n for message(D) of length k, where n-k is the redundancy bits added to make a Code-word of length n, higher the redundancy higher the error correction capability and higher the Bandwidth. Hence, there is a trade-off between error correction capability and bandwidth. C=D.G The size of the Matrix G is (n, n-k) and the size of the Matrix H is (n-k, n). Usually redundancy is defined by the term â€Å"code rate† which is given by R=k/n This varies from  ½ to 1/6. The Encoder produces a Code-word which satisfy the condition C.HT=0 If R is the received data from the Transmitter then the acknowledgement of the correct data received is given by the Syndrome(S). S=R.HT The value of S obtained by the above calculation determines whether the received data is free from error or not, i.e. if S=0 then the received data is free from error, otherwise the received data has an error. Since this property is very useful to reduce the calculation time if we receive the data correctly as soon as we receive data. The probability that the received data needs to be retransmitted which in the range of 10-6 to 10-8. Encoding the data as required is an easy process, but decoding the data effectively and efficiently is a very hard process. The proposed algorithm uses the basic concept of block codes, i.e. R=C+E Where R=noise corrupted vector C=Code vector transmitted over noisy channel E=Error vector. The receiver does not know C and E; its function is to decode C from R, and the message D from C. PROPOSED ALGORITHM The base for LDPC decoding algorithm proposed is as described by MacKay and Neil in 1997. Following are the steps that briefly describe the algorithm STEP 1: INITIALIZATION Let rj be the received vector, i.e. the data received from the Gaussian channel We calculate the components of the vectors d02( j), and d12( j) as: d02( j)= (rj+1)2 d12( j)= (rj-1)2 j = 1, 2, . . . , n (1) These first soft estimates of the code symbols are used to initialise the algorithm by setting the following coefficients q0ij and q1ij at each symbol node q0ij= d02( j) q1ij= d12( j) j = 1, 2, . . . , n, i = 1, 2. . . , . n-k, (2) To eliminate the effect of zero in the calculation the expressions for the calculations can be reduced as shown below ln(em+en) = max(m,n) + ln(1+ e-|m-n|) log2(2m+2n) = max(m,n) + ln(1+ 2-|m-n|)(3) The tables required for calculations are computed using the above formula. The complexity is greatly reduced and the reliability of the transmission of signal is increased. STEP 2: HORIZONTAL STEP aij= f+(q0ij , q1 ij ) bij= −f−(q0ij , q1ij) if (−q 0ij ) ≠¥ (−q1ij ) sij= 0 else sij= 1 cij= ikik if ik is even r0n,ij= −f+(0, cij ) r1n,ij= f−(0, cij ) if ik is odd r0n,ij= f−(0, cij ) r1n,ij= −f+(0, cij ) STEP 3: VERTICAL STEP q0ij= d02 (j) + 0n,ij q1ij= d12 (j) + 1n,ij STEP 4: DECISION rm0ij=r0n,ij+ q0ij rm1ij=r1n,ij+ q1ij if rm02(j)12(j) then c(j) = 1 else c(j) = 0 The LUT entries used in the proposed algorithm for equation (3) and the exact value obtained will vary as shown in the figure. Comparison of BER performance of (8 * 12) LDPC SSD decoder (10 iterations) Comparison of BER performance of (8 * 12) LDPC SSD decoder (50 iterations) As explained above, for higher precision the number of iterations is increased to obtain the same performance of the exact equation. The obtained results approach towards the complex algorithm developed by Gallagher with simple iterative approach and provides a high coding gain compared to uncoded signal. And it provides higher performance at larger iterations. This algorithm provides even higher performance for large length codes. CONCLUSION In this paper we have described Low Density Parity Check (LDPC) codes and decoding of these codes using low complexity algorithms. LDPC codes are used now-a-days in communication systems that take advantage of parallelism, good error correction and high through put. This led to the new algorithm which could decode the errors and yet give similar BER performance as the complex algorithms without the knowledge of the channel noise parameters like variance. This new algorithm is based on repeated use of an antilog-sum operation, and has been simulated on the Tanner graph representation of several LDPC codes and this algorithm can be regarded as a generalized form of belief propagation, where the belief propagated is Euclidean distance estimate rather than a probability estimate. The advantages of the new algorithm are that the performance is as good as the complex algorithm provided the value of base of the logarithm is used properly; that knowledge of noise is not required and that in the simplified form the algorithm needs only additions/subtractions, comparisons and two look-up tables avoiding the use of quotients and products operations that are of high complexity in practical implementations especially using FPGA technology.

Tylenol Essay -- Health, Pain

Acetaminophen is a popular and powerful analgesic that is available over the counter and use worldwide, but is not widely used everywhere in the world. (1) It has been shown to temporally relieve aches, pain associated with common issues such as headache, toothaches, cramps, etc. (1) Acetaminophen can also be used to reduce fever. It has analgesic and antipyretic effects that are very similar to that of aspirin but it lacks the anti-inflammatory effects. (1) The following will explain the pharmacokinetics, pharmacodynamics, and molecular toxicity of acetaminophen. Pharmacokinetics is the study of how a drug is processed in the body by examining absorption, distribution, metabolism and excretion. Pharmacodynamics is the mechanism of the drug at physiological, biochemical and molecular levels in the body. Molecular toxicology is the study of genetic molecules susceptible to external drugs, poisons, pollutants and their interaction with biological systems at a molecular level. For an adult (age 13 and older who are at least 110lbs) the recommended oral dose is 325-1000mg, for a rectal dose it is 650mg, and the total daily dose should not exceed 4000mg.(1) For children, depending on their age and weight, the recommended dose is 40-480mg with no more than 5 doses being administered in one day. (2) For intravenous dosing is very similar to oral dose. The standard recommended intravenous dose is either 1000 mg every six hours or 650 mg every four hours and again no more than 4000mg in 24 hours. (2) Acetaminophen can be administered orally, rectally, or intravenously. Orally acetaminophen is available in tablets/capsules (extended release and regular), chewable tablets, oral granules, and liquid suspensions. Rectally it is adm... ...sired result. This can be viewed by the dose response curve the any drug. Yet, currently there is no dose response curve for acetaminophen in existence for humans and because of this we have been unable to optimize patient therapy without the fear of overdose. (4) In recommended therapeutic doses the drug is tolerated well.(2) Single or repeated doses of acetaminophen do not have any effects on system like the cardiovascular or respiratory. It does not produce gastric irritation or bleeding which may be typical for this type of analgesic. (2) It also has no effect on platelets of uric acid excretion.(2) One may experience skin rashes or have an allergic reaction but that is rare.(2) By looking at the pharmacokinetics is it very easy to overdose or tox out from acetaminophen because the binding potential of the drug is so low and the range of distribution is high.

The Eight Miracle Signs in John

The Eight Miracle Signs in John Jesus performed eight particular miracles in the Gospel of John that revealed His deity. These miracles are unique to study because they all serve towards showing us that Jesus is Divine. They also show different aspects of Jesus’ divinity. Seemingly these miracles were purposeful in their intent towards showing those present with Jesus, and millions that have followed, aspects of Jesus’ power and mission. These miracles serve as a witness to all of us of Jesus’ authority. They also provide comfort when we reflect on the fact that nature, spirit and life all are in His control and hand.Jesus turned the water into wine in John 2:1-11. This was the first visible manifestation of God in Christ. It is interesting that it happened at a wedding. Jesus shows that life with Him happens in our normal day to day activities. It was not performed in a temple or tabernacle, but rather among friends. It was Mary the mother of Jesus who encourage d the miracle to happen. This might show us that God uses our relationships to pull out of us the treasures God puts in us. This miracle shows us that Jesus has power over creation. He takes water and makes it wine. It obeys Him.The water itself is under the control of Christ. One can not help but reflect in the fact that Jesus was present in creation. [1] This miracle is reminiscent of the creation story. In the beginning God moved over the deep. He created out of water. Jesus now initiates His ministry with a miracle with water. The second sign miracle was the healing of the nobleman’s son in John 4:46-54. A man came and called out to Jesus while He was in Cana of Galilee. The man had a son that was sick. This man obviously loved His son. The nobleman asked Jesus to speak a word of healing.The nobleman had enough faith that he felt like a visit was unnecessary. This miracle proved Christ’s authority over space. Space did not limit Jesus. He has all power in heaven an d earth. As it was on that day, it is now. Christ reaches anywhere. The third sign miracle concerns the healing of a lame man in John 5:1-9. The lame man had been unable to pursue healing or help for years. Jesus came by on the Sabbath and asked if the man wanted to made whole. Jesus then told the man to rise and pick his bed up and walk. Under the healing authority of Jesus, the man did.The religious people were furious. The Sabbath had been violated by this lame man picking up his bed! This miracle might represent Jesus divine authority in a few way. Maybe it hints that Jesus is primary over religion and tradition. It definitely shows that Jesus has power over time. Christ knows when and what to do. God knows when to move. The fourth sign in the feeding of the five-thousand in John 6:1-14. A massive group traveled to hear Jesus speak. They walked just to hear Him. The problem is that there was no food for all of these people.The disciple Andrew found a young boy’s lunch and brought it to Jesus. Jesus blessed it and broke it and started to pass it out. Everyone ate. There were even leftovers. This miracle shows that Jesus has power to provide. Even in the food arena. Dr. Towns mentions that it shows that God uses what we give Him and does His work to provide. [2] God has all power and He can provide anything we need. This miracle speaks deeper to the events to come when Christ will be blessed, broken and then passed out to feed the souls of men. The fifth sign comes when Jesus walks on the water in John 6:15-21.There had been a wonderful day of miracles and words from Jesus, but now it is night and Christ has told His disciples to go to the other side of the lake by boat. Huge winds and waves came against the boat in the middle of the night. Jesus, however was walking on the water when the disciples spotted Him. Jesus calmed everything and took them immediately to the other side. This miracle shows God’s power of natural laws. The winds and stor ms obey His voice. The water held Jesus like a sidewalk holds us. All because He has all power. He also caused the entire ship to be transported to the other side.Jesus has all power over natural laws. The sixth miracle sign is the healing of the blind man in John 9:1-12. Jesus and the disciples were walking and passed a blind man. This man, the writer tells us, was blind from birth. In fact, there is some perplexing on behalf of the disciples on wether this is the man’s fault or his parent’s due to sin. Jesus makes clay and tells the man to wash his eyes and the man is healed. This miracle shows God’s power over physical laws. Jesus has all power over physical laws. He heals the blind man’s old eyes much like He made the first man’s eyes.Adam was made from the dust and now Christ makes this man’s eyes â€Å"new† by using dust, spit and authority with power. It shows Christ’s power then and now. The seventh sign miracle was Laz arus being raised from the dead in John 11:1-44. Lazarus was a friend and had been dead for four days. Jesus seemed to purposefully wait until the time of Lazarus’ death and burial. Many of Jesus friends are there. Mary and Martha have partial faith. One believes Jesus could have changed it if He had arrived earlier, and the other believes Jesus can perform it at the Resurrection.Jesus, however, shows that He has power now. All things are under His control. He shows them that He is able, presently, to perform what they wish He could have done in the past and hope He can do in the future. This miracle shows the power of Christ over death. He has power over death itself and the grave. This sign shows that Jesus has the power to give life as a gift. [3] The eighth sign miracle was the amazing catch of fish in John 21:1-11. After Jesus’ resurrection He visited the shore while the disciples were fishing. They had been having trouble all night and had not been able to catch anything.Jesus advised the disciples to try the other side of the boat. The result was a miraculous catch of fish. This miracle showed complete power. It showed that all of the other miracles were fulfilled and found in Jesus. This miracle showed that He was over all things. This is also the miracle that follows the resurrection of Jesus. This miracle was proof, then and now, that Jesus had risen with full power. He shows power over death and nature. He is truly the Son of God. All of these show that Christ has all power. He holds all things and all things are for Him.Jesus deity is proven by the resurrection, but these sign miracles reveal different aspects of His deity. Because of this He can identify with us and provide for us. When we trust in Him it is not our life but His life through us. [4] These precious truths and stories bolster our faith in Christ. Jesus has power over creation. We serve a God that calms storms with His voice. Sicknesses and diseases listen to His will. Time can not change Him or stop Him. Jesus is not limited by space. He can provide anything we need. And the final enemy death was overcome by our Savior. All things are His and we are in His hand.Bibliography John 1:3 Towns, Elmer.
