fiberoptics ENDOSCOPY essays Fiber optics produced by special methods from silica glass and quartz which replaced copper wire is very useful in telecommunications, long distance telephone lines and in examining internal parts of the body (endoscopy). Equipment for photography is available with all current fiber-optic endoscopes. Through a process known as total internal reflection, light rays beamed into the fiber can propagate within the core for great distances with remarkably little attenuation or reduction in intensity. In general, the methods of fiber production fall into three categories; (a) the extrusion method for synthetic fibers; (b) hot drawing of fibers from molten bulk material through an orifice; and (c) drawing of uncoated, coated and multiple fibers from assemblies of rods and tubes fed through a hollow cylindrical furnace. Three forms of fiber optics components have been proposed for the improvement of the image quality, field angle and photographic speed of various types of optical systems. These fiber optics elements, in the form of a field flattener, a conical condenser and distortion corrector, can be used separately or combined into a single unit called a Focon.

Calculus

Calculus Calculus Calculus By Maeve Maddox A reader writes, The other day I heard a radio commentator constantly using the phrase in that calculus, something Id never heard before. [The] commentator was using it in a political context, pretty much as a fancy way of saying in that situation; Id be grateful if you could look into it and cover it some time! Calculus is one of those words like parameter and paradigm that have been yanked from their habitual scientific contexts into the general vocabulary by non-scientists to make their utterances sound more profound. In the context of mathematics, the word calculus is usually preceded by differential or integral: integral calculus: a branch of mathematics concerned with the theory and applications (as in the determination of lengths, areas, and volumes and in the solution of differential equations) of integrals and integration. differential calculus: a branch of mathematics concerned chiefly with the study of the rate of change of functions with respect to their variables especially through the use of derivatives and differentials. Calculus is the diminutive of Latin calx, â€Å"stone.† A calculus was a little stone or pebble. The plural, calculi gives us the word calculation because pebbles were used for counting. Calculi were also used as game pieces and for voting. In the context of medicine, calculus is a hard deposit that builds up in the body to produce kidney stones, plaque, and such. The word calculus is now to be found in a variety of contexts: Competition along routes is just one variable in that calculus. (The context is a discussion of the process of airline pricing.)

2- 527 abdul - Assignment Example For instance, the ISO 9660 standard defines a file system used by CD-ROM media. ISO relies on eight guiding principles for the development of quality products and services, and they are important in improving professionals and other management staff (GCC Standardization Organization, 2014). First, ISO focuses on customers’ wants and customer service. Ideally, every business should relate to customers’ needs and aim at satisfying their needs, or exceeding customers’ expectations (GCC Standardization Organization, 2014). The benefits of this principle included increased profits, customer loyalty, and greater efficiency related to customer satisfaction. The second principle is collaboration of people. This principle states that a company is incomplete without staff and their talents and skills should contribute to the success of the company (GCC Standardization Organization, 2014). The principle promotes creativity and innovation in an organization, employees feel motivated when they use their skills thus, they maximize their abilities, and each employee is accountable for his or her actions. Process approach is the third principle. The principle defines the processes used in order to promote speed and efficacy of activities (GCC Standardization Organ ization, 2014). It is important since it reduces expenses, improves effectiveness of resources, and boosts the productivity of an organization (ISO, 2014). Another principle is leadership. An organization should have defined goals and employees should aim at achieving them. The primary benefit of this principle is employee involvement. Other principles include system approach to management, continuous improvement, logical-based approach, and beneficial supplier relations. ISO standards states that all these principles, aim at cost reduction, efficiency and increased productivity in an organization (GCC Standardization Organization, 2014). The ISO development process involves various

Ancient Egyptians Essay Example for Free

Ancient Egyptians Essay Bill Wilke Egyptians are highly known for their glorious pyramids, powerful pharaohs, and endless amounts of gold and Jewels. When we think of Egyptians we also think of tombs, curses, and cats being a source of protection. However, it is not known to many that they have not only defined the art, but also the meaning behind tattooing. Tattoos are the one thing still captured on the bodies of mummies, in which were discovered from over a millennium ago. Females in particular, had specific tattoos which were used as a therapeutic role during pregnancy and birth. Each tattoo had specific color and significance behind the symbols. Handmade tools were also used in the craft of tattooing during the Egyptian era. Now they have evolved to more dynamic equipment and use of substance. From care to the final product there is a lot of work that goes into preserving tattoos. Written records, physical remains, and works of art have changed our understanding of Egyptian culture. There is good reason to believe that Egyptians were beyond their intellectual ability. Their process of preparing a human as a mummy required countless steps and organization. Ancient writers and modern scientists have both attributed to the knowledge of how this Ancient tradition came about. The remains of Egyptians have been kept preserved because of their tedious attempt in the process of mummification. Mummies, for example, had the protection from chemical exposure, extreme cold conditions, very low humidity, and lack of air when submerged in tombs. The discovery of mummies from Ancient Egypt has also shown us the presence of tattooing. Research and discoveries have pointed out that the art of tattooing was known to Egyptians, and was one of the common practices that were adopted by them. The tattoos found on their remaining bodies were known to be in many sizes, shapes, and colors. One of the earliest evidence of tattoos was identified on mummies dating all the way back from 2000 B. C. The majority of mummies discovered were identified as female, in which were covered with dot like patterns throughout their bodies. Evidence points to the fact that tattoos were an exclusively used practice among females. One of the most famous mummies ever written about was Amunet, who was known as a deity or rather a highly known Goddess (Taylor, 1998). Other than being a traditional royal subject, tattoos had significance for female Egyptians. Lineberry (2007), The tattooing of Ancient Egyptian women had a therapeutic role, and functioned as a permanent form of amulet during the very difficult time of pregnancy and birth (Tattoos, para 5). Pregnancy and birth can be a life changing experience, and for Egyptian women it was also a particular time that they felt the need for protecting themselves. The areas in which were most commonly noted with tattoos during this difficult time were on the thighs, breasts, were placed over wrapped mummies to protect them. She also points out that, it signified keeping everything in (Tattoos, para 5). This pattern is also known as a cicatrix pattern, in which was typically located over the lower pubic region. Tattoos on the abdomen of women, for example, safeguarded them during their pregnancy. As any conscious mother would do for her child, she protects her unborn willingly from harms way. Ancient Egyptian tattoos had many other meanings behind their symbols. Traditionally, Egyptians would use specific drawings as a tribute of sacrifice to a deity. This would mean that an individual would be professing his or her entire belief for someone higher or greater than themselves. Tattoos were presumed to be part of a permanent amulet that could not be lost. An amulet is defined as a trinket, or piece of Jewelry that was thought to have magical protection against evil or disease. In other instances disease would have been another reason that Egyptian females would have acquired a tattoo as well, simply to protect their health while carrying a child. Their significance in symbols also ranged from medical protection to fertility for women. Many tattoos that were used by Egyptians derived from their writing system, which consisted of pictures and symbols. The Scarab, also known as a eetle, was considered a symbol for renewing life. Madhura (2010), It was also considered as one of the many royal titles used by the Pharaohs and was also found to be used by Tutankhamen, one of the most famous Egyptian Pharaohs (Egyptian Tattoo Designs, para 4). He also explains a symbol used called the eye. Madhura (2010), The Ankh or the eye is a widely identified and used symbol of Egyptian culture. In the ancient times, it represented life and was hence one of the respected symbols. Among the different designs of the Ankh, the eye of the Horus is more popular as it stands for the good luck. The eye of Horus, also known as the eye of the Ra, is believed to be the all-seeing eye that was also used in amulets worn by the ancient Egyptians. The Egyptian cross or the Ankh also stands for rebirth or reincarnation. The Egyptian eye tattoo represents light, power and royalty and hence, is a favorite tattoo symbol (Egyptian Tattoo Designs, para 3). Other noted symbols in which were commonly used were the Serket. The Serket is identified as a female fgure with a scorpion on her head. Also used were Kings and Queens, such as Cleopatra, and the Egyptian eye which represents light. Through Egyptian eyes, attoos satisfied various needs and interest as they do today. Their style is captivating and vivid, leading many to believe that this form of art was easily adaptive. The instruments and tools in which were used for tattooing were dated all the way back to 3000 B. C. An Archaeologist by the name of W. M. F Petrie, discovered a tool with a wooden handle and sharp edge at the site of what was called Abydos. He had noted that the tools resembled wide, flattened needles that could potentially make the pattern of multiple dots. Typically these tools would have been used for areas of the ody that females were tattooed for their pregnancy and childbirth protection. The consistency and color was that of dark or black pigment such as soot. It has been said that the Inuit tribe used darker pigmentation or bright colors such as yellow for their tattooing. Inuits are also known for their face tattoos. The tools that are used today have evolved into more intricate ways of use. For example, several needles are used rather than a flat wide needle as the Egyptians had. The more needles you have, the detailed work. Wide range of coloring brings symbols to life as it tells a story. The etails make it look real in a 3D type of way. Instead of soot, ink is the one form of substance that provides color. There are several different types of ink. One type of ink, for example, is black light ink. When the tattoo is under a black light lamp, it will glow. Colors range from the basic primary and secondary colors to different shades. Another option today is the ability to numb the area in which is being tattooed. Egyptians had no means of covering the painful process in which tattoos involved. The care that we provide today goes into the preservation of the tattoo, making it able o last longer. In order for the tattoo to heal correctly you cannot scrub the area, expose it to sun, and it must be able to breathe. Care consists of wiping the skin with antibacterial soap, and then applying petroleum Jelly. Petroleum Jelly is more of a pure substance with no additives and it is easier to work with. It is used widely because it does not cause allergic reactions or pull the ink out. Other forms of Jelly include clear AD Ointment and Bag Balm. No matter what gender a human is, tattoos are more popular today than they were a millennium ago. They represent a erson as an individual, rather than a means for protection. Technology today has given us the ability to express the art of tattooing on a whole new level. Egyptians introduced this ability, in order for individuals to use tattoos to define their stories or personal experiences. Tattoos were once known as frightening and repulsive, and have come a long way since then. Symbols in Egyptian times have been considered generic compared to todays variety. More attention goes into the care of tattoos in todays society during and afterwards. Care is what aids in the conservation of a eautiful piece of art, whether it is a symbol, picture, or words. From medical protection to therapeutic means, tattoos were widely used among Egyptians. With the help of discoveries, female mummies have revealed the remains of tattooing on bodies. We can now understand where tattoos originated from, and how meaningful they were so long ago.

Indian Music Essays -- Music History Musical Arts Essays India

Indian Music The music of India is one of the oldest unspoken musical traditions in the world. The basis of for Indian music is â€Å"sangeet.† Sangeet is a combination of three art forms: vocal music, instrumental music (Indian music). Indian music is base upon seven modes (scales). It is probably no coincidence that Greek music is also base upon seven modes. Furthermore, the Indian scales follow the same process of modulation (murchana) that was found in ancient Greek music. Since Greece is also Indo-European, this is another piece of evidence for the Indo-European connection (Dance and music of India). The vocal tradition is especially strong in Indian music. It is understood that the song is probably the most ancient form of music. Vocal music occupies a considerable part of Natya Shastra (Indian music). The samaveda is the oldest musical text in India. Most of the classical songs of north India are devotional in nature, but there are few genres which are especially oriented toward religion. Most notable is the bhajan, dhun or kirtan for Hindus, the kawali (qawali) for Muslims, and the shabad for Sikhs (Indian music). Not all the music is serious for there are also many popular genres. The gazal is one style, which is known for it rich poetic, and romantic content. The Hindi geet which is basically just a song and undoubtedly the most popular is the film song (Indian music). There are also a few genres which are oriented specifically toward musical education. The most notable example is a genre called lakshan geet. In this style the words of the song actually describe the rag whic h is being performed (Indian music). India also has a rich tradition of folk music. These will vary from region to region. Instrumental music occupies an important position in Indian music. It is one of the threefold aspects of sangeet and has a very ancient history. Instrumental music is known as vadhya sangeet (India, dance and music). Over the years they have become formalized into four major instrumental styles known as: alap, jor, gat and jhala (India, dance and music). The alap is a slow rhythm less elaboration upon the rag. The jor is a section that has rhythm but no developed rhythmic cycle (i.e., tal). The gat is the fully developed piece, while the jhala is a fast rhythmic interplay between the drone strings and the main playing strings (Indian music). The... ...e plucked with a wire finger plectrum called mizrab. There are also a series of sympathetic strings lying under the frets. These strings are almost never played but they vibrate whenever the corresponding note is sounded. The frets are metal rods, which have been bent into crescents. The main resonator is usually made of a gourd and there is sometimes an additional resonator attached to the neck (Indian music). Another famous music instrument is tabla. Tabla is a pair of drums. It consists of a small right hand drum called dayan and a larger metal one called bayan. The tabla has an interesting construction. The dayan (right hand drum) is almost always made of wood. The diameter at the membrane may run from just under five inches to over six inches. The bayan (left hand drum) may be made of iron, aluminium, copper, steel, or clay; yet brass with a nickel or chrome plate is the most common material. Undoubtedly the most striking characteristic of the tabla is the large black spot o n each of the playing surfaces. These black spots are a mixture of gum, soot, and iron filings. Their function is to create the bell-like timbre that is characteristic of the instrument. (Carnatic music).

Journal of the Plague Year and Frankenstein

The Plague and Frankenstein The quest for knowledge is eternal and almost never-ending. People devote their lives to studying and advancing their knowledge, but their advancement is always held in check by society and the people who studied before them. Several novels have been written which explore the effect knowledge and its limitations can have on society. This paper will focus on Defoe’s Journal of the Plague Year, and Mary Shelley’s Frankenstein or the Modern Prometheus. Even though these two novels were written about 100 years apart, they still exemplify many aspects as to why knowledge has limitations. While Defoe’s Journal centers on how to prevent and cure the plague, with a heavy emphasis on religion, Shelley’s Frankenstein has little to no religious affiliation, and focuses on how science and knowledge can potentially lead to evil and misfortune. The plague was a severe and devastating disease which affected Europe multiple times throughout history; each time killing every person who came down with the disease. People are fortunate enough today to have a cure for this disease, but during the 1700s, there was no cure and very little knowledge about proper medical practices. Defoe mentions how signs were posted throughout London, claiming of people who knew of a cure or treatment for the plague, however some of these treatments â€Å"prepared their bodies for the plague, instead of preserving them against it. †1 Thieves and pick-pockets robbed and cheated poor people out of their money with scams, sometimes even poisoning their victims with tonics or â€Å"physicks† that could include such poisons as Mercury in them. These scammers were all throughout the city, appealing to the desires and abundance of the poor. There was no regulation of such business practices and advertisements made ridiculous claims of free help, only to deceive the poor once they got there, forcing them to pay for what may (or may not) help them. These practices were quite cruel and unjust, but people were so scared for their lives that they were willing to do anything which would allow them to live. Not every person in the city fell victim to these scams. Many people once they heard news that the plague had reached London decided to flee and head to some far off town where they might be able to avoid catching the disease. This plight from the city was not only a rational decision, but a religious one as well. Much debate between people in London was sparked about the religious justification for staying in the city, and trusting in God to protect them where they were, or to leave London and â€Å"trust God with [their] safety and health†. 3 For the main character in this novel, H. F. struggles with this decision because he can leave London and live with his relatives, and risk losing all of his possessions, but he ultimately decides to stay, viewing his decision as remaining faithful to God. Upon informing his brother of this decision, he learns that the person, who he was going to entrust with his property during his leave, became ill with the plague, only enforcing H. F. ’s feelings that he made the correct decision to stay in God’s faith. 4 Once the plague hit London with full force, the city was forced to find a new way in which to contain this disease. Instead of looking to the filth with which people lived in, and regarding that it could be carried by animals such as rats, the town determined that each house was to be inspected by doctors, and if the plague should be found within a home, the inhabitants would be locked inside the house, only to come out if they died or the disease had passed. Each home which the plague was found in had a red cross painted on the door, marking it for all to see, and a Watchman was assigned to make sure nobody went in or out of the house, and to run errands for the family if need be. This cruel idea caused many families to parish in their own homes, while others tried to escape by either sneaking out or attacking/threatening the watchmen. In the book Frankenstein or the Modern Prometheus, by Mary Shelley, the underlying theme is how knowledge and power can lead to misery and destruction. In the book, Victor Frankenstein goes off to college and becomes obsessed with several different types of philoso phy and science. He becomes absorbed in â€Å"the secret of life† and he ultimately tries to recreate it. He is successful and brings life to a monster so hideous that even he cannot bear to be around. Frankenstein tries to desert the monster which he created, but he is never fully able to, as the monster follows and spies on Frankenstein and kills part of his family. Frankenstein is appalled that his creation could have begun to cause such horror and pain to people around him, but is worried that if he tells anyone about the monster which he has created, then he himself will look like a madman. The monster himself is eager for affection from humans, but everywhere he goes, he is shunned and forced away from the town due to people being in fear of him. The monster spends much time watching the actions of a family of peasants, where from his hiding place he is able to learn how to speak French as well as read. After some time he ultimately decides that they are a very compassionate family and that he should reveal himself to them, upon doing this, they are disgusted and chase him away. The monster vows to get revenge on Frankenstein and first begins by killing his little brother whom he stumbles across in the forest in Geneva. He then plants the child’s necklace on a friend of Victor’s, to make her appear as the murderer. She is tried for the crime and hung for it. The monster realizes that his only chance for happiness lies within Frankenstein creating him a female companion. He persuades Frankenstein to create him a female saying that he will leave mankind alone forever and go live in some distant land if he has a companion to go with him. 7 As Frankenstein has begun work on his second monster in Scotland, he is reminded of how crazy he became when creating his first monster, and upon catching a glimpse of his monster watching him through the window, Frankenstein freaks out, and destroys the second body which he is creating. The monster upon seeing this is enraged and promises to kill the rest of Frankenstein’s friends and family. This promise holds true, for Frankenstein loses his best friend that night, his wife on his wedding night, and his father. Rather than heed to the monster’s wishes and create a wife for him, Frankenstein was overcome with the guilt of the deaths of his monsters first two victims. He worries that in creating another, he will be creating a duo of evil that will wreak havoc upon the human race. For it was his fault in the first place which let his imagination get a hold of himself and he wanted to create life for himself. This intense lust for knowledge which Frankenstein has ultimately leads to his demise. He becomes mad in his quest and ends up destroying everyone dear to him as well as himself in the end. Both The Journal of the Plague Year and Frankenstein or the Modern Prometheus have heavy themes about knowledge. Defoe’s Journal specifically focuses on how disease was treated and what the methods were to try to cure it. The Journal also has a heavy religious force in it as well. The people in the story as well as the main characters, look towards Bible versus and quotes for guidance in their decision making. This is not the same as in Frankenstein where the main character becomes god-like himself with his creation of life. This major difference is most likely due to the fact that the novels were written about 100 years apart from each other and people’s views how religion affected their daily lives had greatly changed. There is very little mentioned in Frankenstein about religion at all. In each novel, there is excess knowledge than what people have the capacity for; therefore in The Journal, London makes the harsh decision to lock people in their own homes in order to prevent the spread of the plague; while in Frankenstein, his ever persistent quest for knowledge winds up killing him and those dearest to him. The novels are almost a warning as to what effect knowledge can have on society and suggest, that as Socrates said, â€Å"the only true wisdom is in knowing you know nothing. †

Animal and Color Symbolism in Harry Potter Series Essay

An Investigation of J.K. Rowling’s Utilization of Animal and Color Symbolism in Her Harry Potter Series Many consider symbolism the most important factor in comprehending the knowledgeable realm. â€Å"Symbols and metaphors extend into the realm of everyday language and figures of speech† (Biedermann VII). In turn, the Harry Potter novels of J.K. Rowling are extensively â€Å"philosophical† and symbolic (Bagget and Klein 3). Some believe that a civilization that is very advanced will keep records of important symbols (Biedermann VIII). Paralleling this statement, the civilization that J.K. Rowling creates is one â€Å"of menacing trolls and forbidden forests [that] haunts the bestseller lists week in and out, enthralling readers and leaving them hungry for more† (Bagget and Klein 1). Thus the question arises: In what ways and to what extent does J.K. Rowling incorporate animal and color symbolism into her Harry Potter series? Non-fiction animals that exist in reality, as well as in these novels, are utilized as symbols by J.K. Rowling. Owls often seem to be intelligent, tolerant, contemplative, ominous, and nocturnal. (249). Read more:  How many words in the harry potter series. These animals appear â€Å"frequently in the emblems of scholarly publishing houses and book stores† (250). According to Aeppli, cats are considered â€Å"the typically feminine animal[†¦] and females are known as being ‘more deeply rooted in the dark intuitive side of life than man with his simpler psyche’† (59-60). â€Å"The cat is tireless and cunning when going after its prey – the virtues’ of a good soldier† like Professor McGonagall (60). Of course, Rowling includes many super-natural figures. According to Albus Dumbledore, the Headmaster of Hogwarts School of Witchcraft and Wizardry, â€Å"‘[p]hoenixes burst into flame when it is time for them to die and are reborn from the ashes’† (Rowling, Harry Potter and the Chamber of Secrets 207). Dumbledore refers to the usual grandeur of the phoenix and his feathers of scarlet and gold, the colors of Gryffindor (Rowling, Chamber 207). The phoenix, often referred t o as the â€Å"firebird[,]† ignites itself centennially, perishes, and is reborn from the cinders. The phoenix globally embodies â€Å"immortality, death by fire, the sun, and resurrection† (Bruce-Mitford 31). In Harry Potter and the Sorcerer’s Stone, Rowling describes â€Å"a dog that filled the whole space between ceiling and floor. It had three heads, three pairs of rolling mad eyes, [and] three noses, twitching and quivering in their direction† (Rowling, Stone 160). According to Hermione, the dog is blatantly protecting something, for it stands on a disguised door (Rowling, Stone 162). The three-headed dog mainly symbolizes reliability and awareness in mythology; it usually portrays a protector at the entrance to the world of the dead (97). Unicorns have come to signify wholesomeness and power (Biedermann 360). â€Å"According to medieval lore, a unicorn’s horn was a powerful antidote to poison† (28). Unicorns are described as â€Å"pure and incorruptible† (Bruce-Mitford 28). Rubeus Hagrid explains that unicorn blood has the ability to save any life – no matter how near to death – but at an awful cost, having killed an animal of its purity and lack of defense in a selfish manner (Rowling, Stone 258). Mythology, when describing the conception of the earth, depicts dragons as very primitive. The gods are called to overcome these dragons and eventually, their most important descendants become â€Å"dragon-slayers† (102). â€Å"In fairy tales and legends, slaying the dragon is a frequent test of the hero’s mettle† (Biedermann 102). As the dragons are being tended to in Harry Potter and the Goblet of Fire, â€Å"torrents of fire [shoot] into the dark sky from their open, fanged, mouths, fifty feet above the ground on their outstretched necks† (Rowling, Goblet 326). In a Christian view, the dragon can represent the evil counterpart, usually a devil (Biedermann 103). Many main characters in this series are represented by the animals into which they can transform. Because of the rat’s reputation for soiling what is good and carrying sickness, it has become known as a follower of the â€Å"devil, demons, and witches† (279). Peter Pettigrew, a follower of Harry’s evil counter- part, spends many years disguised as a rat. Black dogs have been thought to be in partnership with doers of black magic, yet â€Å"only rarely do dogs appear in a negative light† (97). The Chinese mostly considered them guards against fiends (98). Dogs primarily have a reputation of â€Å"loyalty and vigilance† (97). These are qualities similar to those of Harry’s god-father Sirius Black. To Christians, a wolf is most often the rival endangering those who hold strong faith. Various fables of wolves resulting from murderous individuals exist. The word werewolf is exactly translated to â€Å"man-wolf† (387). As the Latin word for wolf is â€Å"lupus[,]† it is a great foreshadowing tool that the Hogwarts professor with the surname â€Å"Lupin† is in fact a werewolf (387). The first name of said professor, Remus, also seems too well suited to be of coincidence. It appears in â€Å"the Roman legend of the Capitoline wolf that was said to have nursed Romulus and Remus† (Biedermann 389). The deer has great significance in this series. Various older legends of Europe include adolescent females who are changed into does. It was a doe that â€Å"was said to have rescued fleeing Frankish warriors by showing a point at which they could ford the Main River† (Biedermann 97). In Harry Potter and the Deathly Hallows, Rowling describes â€Å"a silver-white doe, moon-bright and dazzling, picking her way over the ground† and Harry senses the â€Å"inexplicable familiarity† of this creature. His mother’s patronus, a symbol used to fight off evil creatures w ith a spell, was a doe identical to this one. Harry realizes that his patronus is inherited from his father when he casts his own spell and sees a stag with prominent antlers. This causes him to recall his father’s nickname, Prongs. (Rowling, Harry Potter and the Prisoner of Azkaban 411) As the mascot of Slytherin House is a snake, it is reasonable that—as reported by an Christian passage, Physiologus—â€Å"the deer spits water into every crevice in which poisonous snakes are hiding; it thus spits them out and tramples them† (92). The deer has been seen as having skin that can act as a talisman to defeat snake poison, and antlers that can be powdered for protection against dark powers (92). Supposedly, â€Å"burnt deer horn drives away any snake† (Biedermann 93). The sorting hat, the judge of how each student is placed into a house, sings â€Å"‘[one] might belong in Hufflepuff, [w]here they are just and loyal, [t]hose patient Hufflepuffs are true [a]nd unafraid of toil’† (R owling, Stone 118). As Hufflepuff is somewhat of a misunderstood house, it is understandable that â€Å"yellow [the primary house color] gives some of the most mixed messages of all. It is the color of pulsating life—of corn and gold and angelic haloes—and it is also at the same time a color of bile, and in its sulphurous incarnation it is the color of the Devil† (Finlay 203). European opinion has dubbed the color cowardly, which coincides with the notion that Hufflepuff is quite inferior to the brave Gryffindor (Bruce-Mitford 107). Rubeus Hagrid states that â€Å"‘Everyone says Hufflepuff are a lot o’ duffers† (Rowling, Stone 80) According to Goethe and his color theory, yellow is â€Å"‘soft and merry’† but can easily become unpleasant (392). A badger—the Hufflepuff mascot—survives off the fat of its own body, which has turned it into a representation of iniquity corresponding to the bad representation of the Hufflepuff house. In the English language, the term â€Å"badgering† is synonymous to irritating (Biedermann 28). The unnerved new students are told that they could prosper â€Å"‘in wise old Ravenclaw, [i]f [they’ve] a ready mind, where those of wit and learning will always find their kind’† (Rowling, Stone 118). The House color blue is primarily known as a representation of â€Å"things of the spirit and the intellect† (Biedermann 44). In order to enter Ravenclaw’s chambers, one is asked to solve a problem. This encourages them to always seek knowledge, according to a Ravenclaw member (Rowling, Harry Potter and the Deathly Hallows 587). Usually, eagles—the house mascot—have favorable connotations. They consist of â€Å"energy, renewal, con templation, acuity of vision, [and] royal bearing† (Biedermann 108). Appropriately, the sorting hat also sings â€Å"[f]or Ravenclaw, the cleverest [will] always be the best† (Rowling, Goblet 177). The wise sorting hat advises new students that â€Å"‘perhaps in Slytherin [they’ll] make [their] real friends, [t]hose cunning folk use any means to achieve their ends’† (118). To Harry’s perception, the Slytherin members appear to be â€Å"an unpleasant lot† (Rowling, Stone 119). A serpent, the representative of Slytherin, originated from the ability of the house’s founder to speak to snakes, a trait that Harry shares (Rowling, Chamber 196). By the Chinese, snakes are considered hazardously cunning. They also believed that the possession of a snake skin signified that a person would become wealthy (312). A snake is capable of murder by biting and utilizing its poison (Biedermann 310). Snakes are often related to demise and disarray (Willis 250). Controlled by the returned Lord Voldemort, a basilisk is hidden deep inside Hogwarts Castle that â€Å"kills people by looking at them† (Rowling, Chamber 291). In the early Middle Ages, the basilisk was attributed with incredible deadly magic. It also, possessed a lethal â€Å"glance and touch† (Rowland 28). According to Moaning Myrtle, a ghost victim of the basilisk, it only takes the glance of a basilisk’s â€Å"‘big, yellow eyes’† to inflict death (Rowling, Chamber 299). In accordance to the beliefs of Christians, basilisks symbolize an evil spirit that can only be stopped by the bible (Rowland 28). Green, Slytherin’s primary color, can represent childishness. â€Å"Especially in English, the color is associated with negative emotions† such as â€Å"envy† and â€Å"jealousy† (Biedermann 159). At one point in time, there was a green color that was undisclosed in China except to the selected royal people. All that was disclosed was its origin of the color green (Finlay 245). This statement parallels the wish of Salazar Slytherin, the founder of the house, to be more particular when admitting students to the school (Rowling, Chamber, 150). The sorting hat declares that one â€Å"‘might belong in Gryffindor, [w]here dwell the brave at heart[.] Their daring nerve and chivalry set Gryffindors apart’† (Rowling, Stone 118). Primarily, red—Gryffindor’s main color—is a sign of â€Å"aggression, vitality and strength, associated with fire and symbolizing both love and mortal combat† (28). Red is commonly the most favored color to an individual (281). To Christians, red is synonymous to Christ’s sacrificed blood, those willing to die for Christ, and ardent affection (Biedermann 282). Upon the instruction of Dumbledore, Harry rotates the sword that previously helped him defeat Lord Voldemort, â€Å"the rubies blazing in the firelight[†¦] [T]hen he [sees] the name just below the hilt[,] Godric Gryffindor† (Rowling, Chamber 333). According to Aeppli, in a dream, red indicates that the dreamer is brave, or equipped to act. Cardinals wear red in order to indicate that they are ready to give up their lives for Christ (Biedermann 282). Accordingly, Harry willingly accepts that â€Å"all that [is] left [for him] [is] the thing itself: dying† to defeat Lord Voldemort (Rowling, Hallows 692). According to [I Peter 5:8]—for Alchemists—lions can represent sulfur, the chief element or â€Å"‘the red lion,’ for the finished ‘philosopher’s stone’† (Biedermann 210). The philosopher’s stone, as it was originally referred to, is â€Å"blood-red† (292). According to Hermione Granger, â€Å"‘Nicholas Flamel[,]’† an alchemist, â€Å"‘is the only known maker of the [Philosopher’s] Stone’† (Rowling, Stone 219). â€Å"In European Heraldry the lion[†¦] is usually red or gold, with its tongue and claws in a contrasting color† (Biedermann 210). After Gryffindor’s defeat of Slytherin for the house cup, â€Å"[i]n an instant, the green hangings became gold [the secondary color of Gryffindor house]; the huge Slytherin serpent vanished and a towering Gryffindor lion took its place† (Rowling, Stone 306). Indeed, symbols are amidst the assets of the world that are the most essential (Biedermann IX). Mostly, the human race doesn’t register the significance of these signs or even their existence (Bruce-Mitford 6). Yet, as J.K. Rowling utilizes them in her Harry Potter series, â€Å"[s]ymbols [†¦] enable people to bring the incomprehensible into the realm of the ta ngible, where they can deal with it† (Biedermann XII).

Marcus Cocceius Nerva, First of Romes Good Emperors

Marcus Cocceius Nerva, First of Rome's Good Emperors Marcus Cocceius Nerva (November 8, 30 CE–January 27, 98 CE) ruled Rome as emperor from 96–98 CE following the assassination of the much-hated Emperor Domitian. Nerva was the first of the five good emperors and was the first to adopt an heir who wasnt part of his biological family. Nerva had been a friend of the Flavians without children of his own. He built aqueducts, worked on the transport system, and built granaries to improve the food supply. Fast Facts: Marcus Cocceius Nerva Known For: Well-regarded and respected Roman emperorAlso Known As: Nerva, Nerva Caesar AugustusBorn: November 8, 30 CE in Narnia, Umbria part of the Roman EmpireParents: Marcus Cocceius Nerva and Sergia PlautillaDied: January 27, 98 CE at the Gardens of Sallust, RomePublished Works: Lyric poetryAwards and Honors:  Ornamenta Triumphalia for military serviceSpouse: NoneChildren: Marcus Ulpius Traianus, Trajan, the governor of Upper Germany (adopted)Notable Quote: â€Å"I have done nothing that would prevent me laying down the imperial office and returning to private life in safety.† Early Life Nerva was born November 8, 30 CE, in Narnia, Umbria, north of Rome. He came from a long line of Roman aristocrats: his great-grandfather M. Cocceius Nerva was consul in 36 CE, his grandfather was a well-known consul and friend of Emperor Tiberius, his mothers aunt was the great-granddaughter of Tiberius, and his great uncle was a negotiator for the emperor Octavian. While little is known of Nervas education or childhood, he did not become a military professional. He was, however, well known for his poetic writings. Early Career Nerva, following in his familys footsteps, pursued a political career. He became praetor-elect in 65 CE and became an advisor to Emperor Nero. He discovered and exposed a plot against Nero (the Pisonian conspiracy); his work on this issue was so significant that he received military triumphal honors (though not a member of the military). In addition, statues of his likeness were placed in the palace. Neros suicide in 68 led to a year of chaos sometimes called the Year of Four Emperors. In 69, as a result of unknown services rendered, Nerva became a consul under Emperor Vespasian. Though there are no records to support the assumption, it seems likely that Nerva continued as consul under Vespasians sons Titus and Domitian until the year 89 CE. Nerva as Emperor Domitian, as a result of conspiracies against him, had become a harsh and vengeful leader. On September 18, 96, he was assassinated in a palace conspiracy. Some historians speculate that Nerva may have been involved in the conspiracy. At the very least, it seems likely that he was aware of it. On the same day, the Senate proclaimed Nerva emperor. When appointed, Nerva was already well into his sixties and had health issues, so it was unlikely he would rule for long. In addition, he had no children, which raised questions about his successor; it may be that he was selected specifically because he would be able to handpick the next Roman emperor. The initial months of Nervas leadership focused on redressing Domitians wrongs. Statues of the former emperor were destroyed, and Nerva granted amnesty to many whom Domitian had exiled. Following tradition, he executed no senators but did, according to Cassius Dio, â€Å"put to death all the slaves and freedmen who conspired against their masters.† While many were satisfied with Nervas approach, the military remained loyal to Domitian, in part because of his generous pay. Members of the Praetorian Guard rebelled against Nerva, imprisoning him in the palace and demanding the release of Petronius and Parthenius, two of Domitians assassins. Nerva actually offered his own neck in exchange for those of the prisoners, but the military refused. Finally, the assassins were captured and executed, while Nerva was released. While Nerva retained power, his confidence was shaken. He spent much of the remainder of his 16-month reign attempting to stabilize the empire and ensure his own succession. Among his achievements were the dedication of a new forum, repairing roads, aqueducts, and the Colosseum, allotting land to the poor, reducing taxes imposed on Jews, instituting new laws limiting public games, and exercising greater oversight over the budget. Succession There is no record that Nerva married, and he had no biological children. His solution was to adopt a son, and he selected Marcus Ulpius Traianus, Trajan, the governor of Upper Germany. The adoption, which took place in October of 97, allowed Nerva to placate the army by selecting a military commander as his heir; at the same time, it allowed him to consolidate his leadership and take control of the provinces in the north. Trajan was the first of many adopted heirs, many of whom served Rome extremely well. In fact, Trajans own leadership is sometimes described as a golden age. Death Nerva had a stroke in January 98, and three weeks later he died. Trajan, his successor, had Nervas ashes put in the mausoleum of Augustus and asked the Senate to deify him. Legacy Nerva was the first of five emperors who oversaw the best days of the Roman Empire, as his leadership set the stage for this period of Roman glory. The other four good emperors were Trajan (98–117), Hadrian (117–138), Antoninus Pius (138–161), and Marcus Aurelius (161–180). Each of these emperors hand-selected his successor through adoption. During this period, the Roman Empire expanded to include the north of Britain as well as portions of Arabia and Mesopotamia. Roman civilization was at its height and a consistent form of government and culture expanded across the entire empire. At the same time, however, the government became increasingly centralized; while there were benefits to this approach, it also made Rome more vulnerable in the long run. Sources Dio, Cassius.

A topic based on a form of mass media - Essay Example Nonetheless, the vast majority of print media have been unshaken by the new wave of online technology where people can easily access online newspapers. Although the advent of online newspapers has posed a great challenge to the print media, the role of print media cannot be overemphasized, particularly in the modern society (Klein, 2009). In this respect, this paper explores and examines the role and future of print news media, especially with regard to the advent and dominance of internet news sources that have had an adverse impact on print news media. Although Gutenberg’s discovery changed the way print media operated in the 15th century, successive technologies in news broadcasting such as television and radio have continued to offer alternatives to print media (Free style marketing, 2014). More recently, the introduction of internet technology has enabled the dissemination of news through the digital media, a development that has not resonated well with the profitability and future of print new media. The leading newspapers like The New York Times and The Washington post, have survived the turbulent broadcast industry amid the introduction of digital news media such as cnn.com and bbc.com (Klein, 2009). Despite the fact that the digital news media have mushroomed in the recent past, they have not been able to phase out the print news media completely because both complement each other (Warner, 2011). In as much as the print news media has managed to stay in the market amid stiff competition from digital news media, it is worth noting that most of the public have shifted to online platforms. Indeed, the vast majority of newspaper readers now read the news in the digital news media using their phones, laptops, and personal computers (Free style marketing, 2014). It means that the print news media have to compete with the digital news media for the same audience at any given time (Warner, 2011). The biggest advantage that the digital news

In what sense, if any, should the study of politics be understood as a Essay

In what sense, if any, should the study of politics be understood as a science - Essay Example In part, politics looks at the way in which these varying needs are met and how the different factors are accommodated. History Politics has been studied since the 4th century B.C. From this time to the present day the topic has been examined in depth, with wide ranging debates and discussion. Greeks were the first one to understand and undertake some prominent changes in the ruling bodies to bring democracy. To implement it efficiently Greeks took politics as a subject to be studied with more rational and systematic approach. Aristotle was the first Greek to introduce the concept of developing a state or a city by uniting small villages together and defined a boundary for particular regulations. He believed in bringing collective and collaborative change through democratic politics. In modern times the discussion of politics consists of many different things. At its heart, politics looks at the way in which the government and governing bodies determine laws as well as how these laws are enforced. There are many different factors that can influence the way in which laws are made. These are examined throughout politics and political study. Some such factors include the effect of religion (Lenski, 1963), race (Gilens, 2000) and gender (Mohanty and Russo, 1991). One question is whether the study of politics can be considered a science. Science can be defined as a systematic study of either a natural or physical phenomena. Science supports and explains the natural phenomenon or natural reaction of a human being to every day issues and the purpose of science are to shape structures which can be useful for real life consequences. It is divided into two kinds, Social Science and Natural Science, however these two main branches can be sub divided into different subjects. Political science is often considered to be a sub division of Social Science. It is the study of government, state, politics and laws to enforce discipline, system and power among all classes and peopl e living within a boundary. Political Science interlinks with other subjects like sociology, psychology, international relations etc which can clearly tell that political science is a vast subject to study with proper guidelines. It gives a complete methodology of practicing political theories democratically with positivity, rationality and defines structuralism and institutionalism (Crotty, 1991). All these theories and depth cannot be observed without a thorough study over a subject. In short, Political Science cannot be kept restricted to specific issues happening in a state or a city but it is a complete solution and should be rightfully used in context of historical, social and cultural matters in our everyday life. Politics Politics is not just the study but a process of making collective and collaborative efforts or decisions to run state affairs effectively and successfully. It is a chain process of building relationships to gain power or authority. In this era, where reacti ons are more discernible and immediate actions cannot be taken, those in authority should be literate enough to deal with the affairs strategically and resolve them in a peaceful manner. Sensitive issues often have large implications, with judgments and laws affecting millions of lives in either positive or negative ways. This process known as politics should be
