Film Techniques Used to Emphasize Themes in V for Vendetta

Film techniques used to emphasize themes in V for Vendetta In the film V for Vendetta, the director, James McTeigue uses symbolism, costume and dialogue to emphasise the idea of everybody having a right to individuality, and the right – and duty – to resist forced conformism. James McTeigue uses symbolism in the film V for Vendetta to juxtapose the idea of individuality and the resistance of forced conformity. The first important symbol used in the film is V’s mask.This symbol is shown in all of the scenes V appears in and again in the very last scene. In this scene thousands of citizens gather wearing the masks and remove them. Masks often symbolize a character hiding their identity. This final scene when the citizens remove their masks is important for emphasising the theme. The citizens show that they are no longer willing to allow themselves to be forced into conforming, that instead they will resist.The other important symbol used by the director is mirrors; at the beginning of the film we are introduced to the characters of Evey and V as they put on their masks for the evening in their mirrors. V is also seen reflected in Delia’s eyes during the fire at Lark Hill. Mirrors often symbolise an unknown identity or not seeing yourself for who you really are. McTeigue uses both of these symbols to juxtapose the right to individuality and the right- and duty – to resist forced conformism.He shows the characters in the film doing the opposite of this to emphasise why the viewers need to fight to preserve their own individuality. When speaking in an interview with Ryan Lambie on March 2nd 2012, McTeigue was asked how he feels about people using the masks for political protests and other such activities, McTeigue replied â€Å"I think the mask is a good way for people to feel free to do things they might not normally do† this statement shows McTeigue’s desire for the public to fight for their individuality and resist conforming to the wishes of the government.The second visual feature used by the director in this film is costume. McTeigue shows a change in costume in the character Evey from the beginning to the end of the film, in order to emphasise Evey’s resistance to forced conformism and her journey to find her own individuality. At the beginning of the film, Evey dresses to blend in with the crowds; she wears light colours, nothing that stands out. However towards the end of the film, V helps Evey to lose her fear and discover who she is.He shaves her head. After this point in the film Evey begins to wear darker coloured clothing such as blacks and greys, and wears her bald head with pride. She does not cover it with wigs or hats. This is similar to the costume changes shown in the film the Matrix, which James McTeigue helped direct. While in the Matrix the characters wear darker clothes, these colours show a change in attitude and the characters’ desires to resist being cont rolled and forced into conformity by the Machines.This change in costume is similar to that of V for Vendetta, which shows Evey’s new-found confidence in her identity, and her willingness to resist conforming to the totalitarian society she lives in. In doing this, the director urges viewers to try to find their own individuality and resist the conformism in their own lives. He uses this film to warn viewers of the dangers of not resisting forced conformism, through the lack of change in costume in the other characters.In 2011 an article was posted on Enotes which reads â€Å"V's legacy for change is embodied in Evey, which is reflective of how individuals have to make a conscious choice to embody dissent and resistance†¦ The end desire for anarchy is nothing more than a realization of individuality and individual choice†¦ individuality and personal notions of identity are the opposing forces to totalitarianism†¦ the need for individuality is seen as the antid ote to a realm where political control is contingent on silence and a lack of individuality. Plainly put the author means that V for Vendetta shows that in order to avoid totalitarianism the public must protect their individuality and resist forced conformity. One of the most important verbal techniques used by James McTeigue is dialogue. The director shows the characters’ lack of individuality and resistance to conformity through verbal speech. During the second act of the film V for Vendetta, Gordon states â€Å"When you wear a mask for so long, you begin to forget who you were beneath it†.This statement not only emphasises the symbolism in the film but also shows Gordon’s lack of resistance to forced conformity. McTeigue chooses this line of dialogue to state the need to prevent putting on the mask to begin with. He wants viewers to believe that their individuality is important and they shouldn’t allow society to remove it from them. When asked by Evey to remove his mask near the end of the film V states â€Å"Evey, please . . . there is a face beneath this mask, but it's not me.I'm no more that face than I am the muscles beneath it, or the bones beneath them. † By which he means that his identity is not based on the person beneath his mask, he is who he chooses to be. McTeigue uses this line of dialogue to show viewers that their identity is not decided by how they look, that they can choose their own identity by fighting for their individuality. James McTeigue uses symbolism, costume, and dialogue to emphasise the right to individuality and the right – and duty – to resist forced conformity in the film V for Vendetta.

First world war poetry Essay

First world war poetry 39†² faris-slm Web definitions A war poet iS a poet written at that time and on the subject of war. This term, at the beginning applied especially to those in military service during World War I. then, documented as early as IS4B in reference to German revolutionary poet, Georg Herwegh The main figures in the first world war Siegfried Sassoon (1886-1967)-1 Siegfried Sassoon was perhaps the most innocent of the war poets. John Hildebdle has called Sassoon the â€Å"accidental hero. Born Into a wealthy Jewish family In 1886, Sassoon lived the pastoral life of a young squire: fox-hunting, playing cricket, golfing nd writing romantic verses. Being an Innocent, Sassoon’s reaction to the realities of the war were all the more bitter and vlolent both his reaction Trough his poetry and his reaction on the battlefield (after the death ot fellow officer David Thomas and has brother Hamo at Gallipoli). Sassoon sadness, he believed that the Germans were entire ly to blame. Sassoon showed innocence by gong public to protest against the war. Luckily. his friend and fellow poet Robert Graves convinced the review board that Sassoon was suffering from shell-shock and he was sent instead to the military ospital at Craig Lockhart where he met and influenced Wilfred Owen. Sassoon is a key figure in the study of the poetry of the Great War: he brought with him to the war the ideal pastoral background. he began by writing war poetry reminiscent of Rupert Brooke. he wrote with such war poets as Robert Graves and Edmund Blunden. e spoke out publicly against the war. he spent thirty years reflecting on the war through his memoirs, and at last he found peace in his religious faith. Some critics found his later poetry lacking in comparison to his war poems. How to Die† ‘ Dark clouds are smouldering into red While down the Craters morning burns The dying soldier shifts his head TO watch the glory that returns He lifts his fingers toward the skies Where hol y brightness breaks in name: Radiance reflected in his eyes, And on his lips a whispered name. You’d think, to hear some people talk, That lads go West with sobs and curses, And sullen faces white as chalk, Hankering for wreaths and tombs and hearses. But they’ve been taught the way to do it Like Christian soldiers: not with haste And shuddering groans: but passing through it With due regard for decent taste. From the age of nineteen Owen wanted to be a poet and immersed himself in poetry, eing especially impressed by Keats and Shelley. He wrote almost no poetry of importance until he saw action in France in 1917. He was deeply attached to his mother to whom most of his 664 letters are addressed. (She saved everyone. ) He was a committed Christian and became lay assistant to the vicar of Dunsden near Reading 1911-1913 – teaching Bible classes and leading prayer meetings as well as visiting parishioners and helping in other ways. He escaped bullets until the last week of the war, but he saw a good deal of front-line action: he was blown up, concussed and suffered shell-shock. At Craig Lockhart, the psychiatric hospital in Edinburgh, he met Siegfried Sassoon who inspired him to develop his war poetry. He was sent back to the trenches in September, 1918 and in October won the Military Cross. by seizing a German machine-gun and using it to kill a number of Germans. On 4th November he was shot and killed near the village of Ors. The news of his death reached his parents’ home as the Armistice bells were ringing on 11 November. Wilfred Owen is the greatest writer of war poetry in the English language. He wrote out of his intense personal experience as a soldier and wrote with matchless power of the physical, moral and psychological impact of the First World War. All of his great war poems about his reputation rests were written only in a fifteen months. Anthem for Doomed Youth BY WILFRED OWEN What passing-bells for these who die as cattle? Only the monstrous anger of the guns. Only the stuttering rifles’ rapid rattle Can patter out their hasty orisons. No mockeries now for them; no prayers nor bells, Nor any voice of mourning save the choirs,† The shrill, demented choirs of wailing shells; And bugles calling for them from sad shires. What candles may be held to speed them all? Not in the hands of boys, but in their eyes Shall shine the holy glimmers of good-byes. The pallor of girls’ brows shall be their pall; Their flowers the tenderness of patient minds, And each slow dusk a drawing-down of blinds In England For the first time, am essential number of important English poets were soldiers, writing about their experiences of war. A number of them died on the battlefield, most famously Rupert Brooke, Edward Thomas, and Wilfred Owen. Siegfried Sassoon survived but were scarred by their experiences, and this was reflected in their poetry. Wilfred Gibson (1878-1962) -3 Wilfred Wilson Gibson was born in Hexham, England in 1878. Gibson worked for a time as a social worker in London’s East End. He published his first verse in 1902, Mountain Lovers. He had several poems included in various Georgian poetry 1910. After the outbreak of war, Gibson served as a private in the infantry on the Western Front. It was therefore from the perspective of the ordinary soldier that Gibson wrote his war poetry. His active service was brief, but his poetry contradict his lack of experience, â€Å"Breakfast† being a prime example of ironic war verse written during the very early stages of the conflict following the armistice, Gibson continued riting poetry and plays. His work was particularly concerned with the poverty of industrial workers and village workers. Back They ask me where I’ve been, And what I’ve done and seen. But what can I reply Who know it wasn’t l, But someone Just like me, Who went across the sea And with my head and hands Killed men in foreign lands†¦ Though I must bear the blame, Because he bore my name. str Herbert Read (1893-1968) -4 the poet and critic, was born in France, Yorkshire in 1893 His college studies, at Leeds University, were interrupted by the outbreak of the First World War, in which he served with the Yorkshire Regiment in France and Belgium. During his service he was awarded the Distinguished Service Order (DSO) and Military Cross in the same year, 1918. Read wrote two volumes of poetry based upon his war experiences: Songs of Chaos (1915) and Naked Warriors, published in 1919, along with two volumes of autobiography, In Retreat (1925) and Ambush (1930). He became an outspoken pacifist during the Second World War. He continued to publish poetry for the remainder of his life, his final volume, Collected Poems, being published in 1966. As a literary critic he championed the 19th-century English Romantic authors, for example in â€Å"The True Voice of Feeling† Studies in English Romantic Poetry . Ernest Hemingway -5 Ernest Hemingway, the son of Clarence Edmonds Hemingway, a doctor, was was born in Oak Park, Illinois, on 21st July, 1899. His mother, Grace Hall Hemingway, was a music teacher but had always wanted to be an opera singer. According to Carlos Baker, the author of Ernest Hemingway: A Life Story (1969), he began writing stories as a child: â€Å"Ernest loved to dramatize everything, continuing his boyhood habit of aking up stories in which he was invariably the swashbuckling hero†. When the United States entered the First World War in 1917 Hemingway attempted to sign up for the army but was rejected because of a defective eye. He therefore Joined the Red Cross as an ambulance driver. He later wrote: â€Å"One becomes so accustomed to all the dead being men that the sight of a dead woman is quite shocking. I first saw inversion of the usual sex of the dead after the explosion of a munition factory which had been situated in the countryside near Milan. We drove to the scene of the disaster in trucks along poplar-shaded roads. Arriving where the munition plant had been, some of us were put to patrolling about those large stocks of munitions which which had gotten into the grass of an adjacent field, which task being concluded, we were ordered to search the immediate vicinity and surrounding fields for bodies. We found and carried to an improvised mortuary a good number of these and I must admit, frankly, the shock it was to find that those dead were women rather than men†. A Farewell to Arms (1929), Hemingway’s great novel set against the background of the war in Italy, and eclipses the poetry dealing with his war-time experiences.

Case Study BA - Essay Example Few widely known facts about the terminal 5 are: Information Systems employed by BAA seems to have incorporated great ideas but they forgot to actually implement the ideas. They had ample car parks and had segregated car parking spaces for public and staff but people and staff could not find the car parks and spent lot of time trying to look for parking spaces. The problem being, the details of parking spaces (no. of slots, in use, empty etc.) were not updated in the information system database and were not displayed at appropriate places for people to see. One of the biggest faults in their system was that the staff at baggage handling and sorting section were not able to log on to their computers. This affected both incoming and outgoing baggage. The security checkpoints were not updated to the staff. There were no maps or location guidelines. Search facility was not ready for both staff and passengers. As far as the methodical preparations for terminal 5 are concerned, BA Authority did have some Information Systems in place. However, the Information System was highly ineffective. The reasons for it being ineffective may be incompetent people in the IT management team, lack of exposure of IT engineers with regard to such a large scale implementation as was terminal 5 of Heathrow airport or any other. The ineffectiveness of the Information Systems can be realized due to the following problems that occurred in terminal 5 on the very first day of its opening. Car Parks and parking spaces were not well managed. No software was employed to keep track of full and available parking spaces. Designated car parks for staff were not available and there were no sign board or any other means to locate the car parks due to which public and the staff spent lot of time looking for parking spaces. There was no signage at any place in the terminal. The terminal should have been equipped with monitors displaying the map of

Even when the Hispanic population in the US has increased 57.9% from 1990 to 2000, little or no attention has been given to the differences in subcultures (e.g. language). Numerous studies have shown that organizational commitment predicts important variables including absenteeism, organizational citizenship, performance, and turnover intention. Additional studies have determined that Human Resources Management (HRM) practices such as compensation and incentives, performance appraisal, and training have the potential to influence employee’s commitment in the public and private sector, but research is needed regarding organizational commitment in the construction industry. This study will explore the relationships between employer-provided training, compensation and benefits, and organizational commitment of construction project managers in Puerto Rico. The population under study will be Project Managers of construction companies. The data will be collected utilizing a four-part questionnaire. As part of this study, the effects of gender, age, English or Spanish speaking, education level, overall project management experience, tenure with current employer and professional certification status on organizational commitment will be studied.

Bribery, Corruption and Social Responsibility Essay

Bribery, Corruption and Social Responsibility - Essay Example (Business for Social Responsibility) With this background this paper attempts to make a report suggesting the possible course of action for the executive of the company BIM taking into account the broader issues of the company's ethical policies, its social responsibility and the so called social evils of bribery and corruption, Job and wealth creation in society is the primary objective of businesses. According to Canada's business and consumer website the role of Corporate Social Responsibility (CSR) is to position the companies to both proactively manage risks and take advantage of opportunities especially with respect to their corporate reputation and broad engagement of stakeholders. The stakeholders group includes shareholders, employees, customers, communities, suppliers, governments, non-governmental organizations, international organizations and others affected by the companies' activities. It is assumed that through CSR enterprises can play an important role in preventing and combating corruption and bribery and in helping preventing the use of enterprises for money laundering and criminal activities financing. In the instant case the for Thomas the question before him is whether to follow the code of Ethics of his company with respect to the use of bribery and loose the four years background work done by spending $ 30 million of the shareholders money and a lucrative opportunity of turning in a good business for the company or To follow the accepted practices of the country, pay the necessary bribes and get the contracts signed for the company ignoring the company's code of ethics. The question is to be looked into from the angle of the social responsibility of the company in so far as how it proactively manage the risks and take advantage of the opportunities. By not paying the bribe and losing the business opportunity Thomas is not doing justice to The shareholders whose valuable money of $ 30 million is spent on developing this project. Quite obviously the bribery practice in Lagos or Nigeria has not started after the decision to work on the project. Hence Thomas and the Company should have knowledge on these practices even before the decision on the project is taken. The code of ethics is a subsequent development as the background work for the project is being carried out for four years now. Hence to withdraw now from the project at a stage when the efforts are going to give benefit to the company is doing injustice to the shareholders and against the principle of corporate social responsibility The part of employees who have been recruited for the project, since the company may decide to retrench them in case the project is not taking off. It is none of their fault that the director or the company is not aware of the prevailing practices of bribery and corruption in the country of operation. In any case they should not be penalized. If they are it is against the so called Social Responsibility The issue needs to take into

Read the requirment carefully and finish on time - Essay Example 59). According to the company’s handbook (1935, p 10), the company began its business by erecting numerous roadside dangers and other warning signs. The company was in charge of road signs until early 1930s when the local authorities took control of the signs. The achievements gained by the company were destroyed when most of their road signs were destroyed during the Second World War. By then, the company had erected approximately 6,500 direction signs and 15,000 village signs (The Automobile Association Handbook). The company published an AA Member’s Special Handbook in 1908. By using the handbook, the company’s clients could find the location of AA agents across the country and mechanics. The clients also received free legal services for one year (Passmore 2003, p. 62). The company has grown from a small company to become on the leading companies in the world. The motor insurance service has grown to become one of the largest in London and the United Kingdom a t large. The insurance industry is experiencing growth that is generated by new entrants with new products and way of doing things. It is due to these factors that the company needs to explore means of ensuring that it remains among the best service providers in this industry. SWOT Analysis Strengths The Automobile Association has various strengths that it can exploit to gain a competitive edge in the market. The first strength the company has built over the years is its reputation of being reliable in providing services. The company’s clients need not worry when they are in some form of discomfort since they trust in the company to deliver. The company is also renowned for having qualified and competent staff. This includes qualified mechanics for the garage sections and the staff in other areas. Weaknesses Despite having the above notable strengths, the company also has some weaknesses that can be exploited by the competitors. The competitors in the British market arise fro m firms such as RAC and Green Flag and Direct Line and a host of many other small players (Harison & John, 2008). The second placed RAC is becoming a serious threat to the existence of the company. The company offers all the services that the Automobile Association offers in addition to security services. This therefore means that the company has a more complete package than the Automobile Association even though they are still young in client size. The second weakness of the company is the high employee turnover. On one hand, the rivals lure some of the employees away from the company with huge salaries. Since the Automobile Association is renowned for having top class employees, the competitors target these employees instead of struggling to breed their own. On the other hand, some of the employees such as mechanics use the money from their savings to open their own businesses using the reputation of having worked for the Automobile Association. Opportunities The current economic condition is tough on some people. This people however require motor insurance and other related services. These types of people will therefore look for cheaper options that also provide quality and reliable services. The company can gain from such people by introducing products for all classes of people. The other option that could be more profitable is for the company to merge with one of the competitors such as RAC. This would

Environment and development Essay Example | Topics and Well Written Essays - 4000 words

Environment and development - Essay Example What is perceived of the term ‘Ethical Consumption’, at the very basic level, is the buying, purchasing, consuming or to obtain something for one’s own personal or (at least related) use; keeping in mind the ethical values one has established for one’s own sake. Now different people may have different ethical values but beings with similar ethical values tend to form groups and societies as illustrated by Stuart Hall: â€Å"†¦the word can be used to describe the ‘shared values’ of a group or of a society† (Hall , p.2). These groups tend to act as mass ‘effectors’ and can really bring change in lieu of what they consider ethically right or wrong. However, the correctness of their own ethical views does not matter in this regard since most people form almost the same ethical values concerning certain aspects of our planet, the humanity and the environment. Now people who buy, with reference to their own established Ã¢â‚¬Ë œethical standards’ of shopping or consuming to be more precise may consider a certain product to be ethically wrong or being produced in a manner which is ethically wrong or its very production effects certain aspects which the consumer tends to care about, and hence considers the production ethically wrong; now this consumer, who considers a product to be immoral may boycott its purchase or avoid it at all possible costs, at least that’s the general perceived reaction from a consumer who buys in accordance to his ethical standards. And the same can be expected off a certain group formed due to similar ethical standards concerning a certain product, and it is quite evident that the group and even the individual alone can affect the market value of that certain product in a positive (if the product meets their ethical standards) or negative (if the product does not meet their ethical standards) manner. But it is not always the case that the consumer considers buying wi th respect to his/ her

Bleeding Kansas Leading to Civil War Research Paper - 1

Bleeding Kansas Leading to Civil War - Research Paper Example There are several events that resulted into the secession which finally led to the civil war in America. 2Progressively, there are several events that finally broke the civil war and Americans found themselves in the fight. They include; The Mexican war of 1848, fugitive slave act of 1850, the release of Uncle Tom’s cabin, Bleeding Kansas, attack of Charles Summer, the decision by Dred Scott, rejection of the Lecompton constitution, Harper’s Ferry Raid by Brown, Election of the Abraham Lincoln as the president of the U.S. However, it is important to note that Kansas-Nebraska Act was one of the most instrumental events that led to civil war. This paper has therefore outlined the events that took place at the moment when the act was passed as well as ho it resulted into the civil wars. This act gave the Kansas and the Nebraska the opportunities to decide for themselves what they wanted to take place. They were given the opportunity to decide for themselves whether they wanted to sop slavery or whether they wanted to continue with the slavery activities. As a result of this, there were divisions in the minds of individuals in these states. As a result, there was a clear battle line between the pro and the anti-slavery idea. These wars therefore became some of the events in the war that finally led to the civil war in the United States of America. Bleeding Kansas is therefore a term that refers to the different and consequential violent activities that took place in several parts of the Kansas state. 3The violent activities were mainly between those who supported the slavery and those who were against the slavery. It is important to note that this was a civil war of its own because the government had already passed legislation for the people to choose what was good or bad for them. These events took place between the years 1854 and 1858 and resulted into several issues that were difficult to resolve at that time and hence there was increasing

Crystals Research Paper Essay Example for Free

Crystals Research Paper Essay Crystals form in the depths of the Earth to the extension of the clouds in sky. Some think that crystals elude the sight of people’s eyes everyday in life, but they are everywhere including ingredients for food, construction materials, and even in ice-cold weather. The crystals in this experiment are ammonia-generated crystals that can be created right in a home. The experiment will be testing the different effects and products on crystals in different temperatures and forms of light. Different measurements will be recorded throughout the experiment such as mass and length. But first the crystals must grow. The scientific study of crystals and crystal formation is called crystallography. All over the world, though the different ages of man, crystals have been found to take their place throughout different cultures, countries, and religions. Not only were crystals used for a part in the currency of some ancient economies, but also they date back as far as 1500 BC as a source of healing and medicinal uses. â€Å"The ancient Egyptians strongly believed in the healing and protective power of crystals. Many pharaohs wore crystals on their headdresses and many crystal amulets have been found in their tombs.† Pharaohs of ancient Egypt often believed that the use of crystals in the masks and jewelry gave them the effect of bettering their rule. Amazonite and Lapis were reoccurring crystals found in the tombs found in Egypt, particularly King Tut where Lapis was actually apiece in the famous mask he wore. Cleopatra’s favorite jewelry was supposed to be a ring made of the crystal am ethyst. The ancient Chinese are also found to be users of the healing purposes of crystals. In two hundred different occasions, crystals are referred to in the bible. New Jerusalem, God’s heavenly city, was said to be built on top of crystals. â€Å"And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass. And the foundations of the wall of the city were garnished with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald; The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst. Tibetan monks also viewed quartz crystal spheres as holy objects and worshiped them. The monks often referred to quartz as the â€Å"crystal of enlightenment†. Alexander The Great included a large emerald crystal encrusted in his battle helmet to insure a victory in the battle. The Shah Jahan, monks who built the Taj Mahal, wore talismans similar to Alexander The Great. Overall, There is a reoccurrence of crystals used for different purposes such as healing, sacred items, and fine jewelry. There are many different structures of crystals based on the formation of them. The different forms are Cubic, Isometric, Tetragonal, Orthorhombic, Hexagonal, Trigonal, Triclinic, and Monoclinic. Cubic and Isometric are similar but don’t always have to be cubes. They can be found in forms of octahedrons and dodecahedrons as well as cubes. Tetragonal form double prisms and double pyramids due to one axis being longer than the other. Orthorhombic form dipyramids and rhombic prisms. Hexagonal are six-sided prisms and when viewed from a certain angle, the cross section is a hexagon. Trigonal, instead of having a 6-fold axis like the hexagonal, it has a 3-fold, thus making it trigonal. Triclinic has no set shape so these kinds of crystals can come in any shape and strange ones as well. Monoclinic are very similar to tetragonal crystals except they are skewed a bit so they don’t form good angles. These formations of the atoms and molecules in a crystal are all part of what is called the crystal lattice. The crystal lattice is the repetition of a pattern in three dimensions. The atoms and molecules of crystals form in such a way that in all three dimensions, they are repeating a certain pattern. The shapes of the microscopic atoms can determine the shape of the macroscopic crystal. So, Cubic, Isometric, Tetragonal, Orthorhombic, Hexagonal, Trigonal, Triclinic, and Monoclinic atom formations repeat in different crystals to make them the shape they are. Crystals can also be grouped by their properties. The property arrangements include covalent, metallic, ionic, and molecular crystals. Covalent crystals have many true covalent bonds connecting all the atoms in the crystal. Covalent crystals tend to have very high melting points. Some covalent crystals include zinc sulfide and diamonds. Metallic crystal’s atoms sit on a lattice, therefore the outer electrons of the atoms in the crystal are free to move around and float whichever way they want. Metallic crystals have a high melting point like covalent crystals but just not as high. Ionic crystals are bonded together by ionic bonds just as covalent crystals are held together by covalent bonds. Ionic crystals have high melting points like the other crystals and are usually very hard. An example of an ionic crystal is salt (NaCl). Molecular crystals are very recognizable in terms of their molecular structure. They are bonding by hydrogen bonds or non-covalent bonding. Molecular crystals are usually soft and have lower melting points compared to the other crystals. Relating the properties of crystals to the atom structure (crystal lattice) will allow one to realize how the structure correlates to the property. They’re ere 2 different types of structure in the crystal lattice, crystalline and non-crystalline. Crystalline structures are the atom structures that contain the repeating patterns. While non-crystalline structures contain miniscule faults in the patterns and are not perfect. Ionic crystals contain a crystalline structure and therefore are very hard and dense. The more crystalline the structure, the more compact the atoms are arranged. And the more the compact the atoms are, the more dense and hard the crystal becomes. Molecular crystals tend to have a weak, non-crystalline structure of the atoms. This results in the Molecular crystals being weak with low boiling points. The atoms in Molecular crystal tend to be spread out over farther distances in contrast to ionic crystal’s structure. Different wavelengths and colors of light can affect the color of the crystal itself and the wavelength output of the crystal. Different crystals are different colors due to the different chemicals in each one and how each one absorbs light. Many crystals reflect a certain color of light depending on the chemicals. So, crystals absorb one color of light or wavelength of light, and reflect a different color of light. So the idea of complimentary colors comes into play. Complimentary colors are the colors that the crystals absorb to then reflect a different color of light. There are many examples such as if a crystal is yellow, it is reflecting yellow light but the light it absorbs is blue. Also, if a crystal is red, it is reflecting red light but it is absorbing green light. Normally, crystals will grow much faster in the light, but these crystals will be much weaker than crystals grown in the dark. This is due to the time it takes for each to grow. In dark rooms crystals grow at a much slower rate but are significantly stronger than crystals grown in light. Crystals are found all over and all inside the Earth. In some rock cavities, whether it is close to the surface or deep and closer to the core of the Earth, mineral-rich solutions contain the essential elements to grow crystals. Thus, in these rock cavities, many different crystals can be found, and some are very old. Crystals can also be found around volcanoes and past eruption areas because after a volcano erupts, the cooled magma forms crystals. In many caves, rock walls contain similar solutions as rock cavities and form similar crystals. Crystals can also be found where there are mineral-rich vapors present, such as deep caves and rock formations. Many different crystals can form in various environments. Such as the location of turbulent water such as pipes and quick paced streams. Also, crystals can be found in the presence of evaporating salt water, where salt crystals will form. Crystals are also formed in the process of condensation, or in clouds for that matter. Every time it snows, the water has frozen into microscopic ice crystals that are the snowflakes. Also, Crystals can form under water and many on the Earth have not been seen because of this. Crystals grow and form in different and various ways. Crystals begin growing in a process called nucleation, which contains 2 different types, unassisted and assisted. Unassisted nucleation occurs when a â€Å"proto-crystal† forms in the solution that has been added to a solute. The solute is the solid and the solution is the liquid surrounding the solute. When molecules in the solution begin to attract to one another they combine and sometimes are separated by intermolecular forces but sometimes they stay together. When these molecules stay together they begin to attract different molecules of the solution to join and this is the â€Å"proto-crystal†. The â€Å"proto-crystal† then attaches itself to a couple other molecules or other â€Å"proto-crystals† in the solution and the actual crystal begins to form. In assisted nucleation, the solution is provided with a solute that the molecules of the solution can attach or adsorb to. When this occurs it attracts molecules just as in unassisted nucleation and the crystals begin to form. Because of the ability for crystals to grow from the build up of the solute molecules in the solution, crystals are able to grow at their highest when the solution being used is saturated with the solute being use. The more material to build up, the more the crystals are going to be able to grow and grow to full extent. Crystal formation is very slow, so it must be given a long geological process to form. Depending on the kind of crystal, the times of formation vary, so some form faster than others. This is where super saturation comes into play. Super saturation is the presence of more dissolved material in the solvent that could be dissolved in normal conditions. When a solution is supersaturated, it contains many particles and molecules of material to begin the nucleation process. When the supersaturated solution is under the correct conditions, crystallization begins to occur more rapidly. But this is not the case for all liquids or solutions. Some solutions may be saturated at one temperature but supersaturated at another so temperature is able to affect this as well. Temperature plays a huge part in the growth and the rate in which crystals grow. The growth rate of crystals changes depending on the temperature they are in. But some crystals grow faster in warm temperatures than in cold temperatures. This is because of the process of evaporation. When a saturated solution is in a warm environment it begins to evaporate. When the liquid begins to evaporate, overtime the material that was once dissolved in the solution will begin to bunch up and crystallize the more the liquid evaporates. But this process is a lot quicker than in cold environments so this leads to less stability and weaker crystal strength. In colder environments, the opposite process is used to begin the crystallization process. The process of precipitation is used. This process takes a much longer time than the evaporation process. Since this process takes a much longer time, it has the ability to create well formed and high quality crystals that are much stronger than crystals formed in hotter temperatures. Mainly crystals grown in the dark take much longer to grow. Because of the absence of light, there is not as much heat than crystals in light. Crystals in light receive much more heat. But this is not the case for all types of crystals; in some cases the rules for temperature are switched. For example Borax, these are crystals that usually generate faster in colder temperatures. If the Borax solution is saturated at room temperature or at any temperature higher than room temperature, the crystals grow faster in colder temperatures. This is due to the molecular structure of the Borax solution and the movement of the molecules causes the saturated solution at room temperature to become a supersaturated solution at colder temperatures. And the super saturation leads to faster crystal growth. So growth rates vary depending on temperature, kind of crystal, and kind of solution being used in the experiment. Bibliography 1.Crystal.

Aphrodisiac Activity of Vigna Mungo Seeds

Aphrodisiac Activity of Vigna Mungo Seeds Pharmacological Evalution of The Potential Aphrodisiac Activity of Methanolic and Chloroform Extracts of Vigna mungo Seeds in Male Albino Rats Ravindra Babu Sajja, Eknath Royal P, Suneetha B, Sunanda S ABSTRACT The present study was conducted to investigate the aphrodisiac activity of methanolic and chloroform extracts of seeds of Vigna mungo (MEVM and CEVM) in male albino rats. The aphrodisiac activity of MEVM and CEVM wasevaluated by observing sexual behavioral parameters including Mount frequency (MF), Mount latency (ML), Ejaculatory latency (EL), Intromission latency (IL), Intromission frequency (IF), Ejaculation frequency (EF) and Post ejaculatory interval (PEI) and biochemical parameter like serum testosterone concentration in male rats. Both extracts were administered orally at doses of 200mg/kg and 400 mg/kg, showed a significant increase (P Vigna mungo. Keywords: Vigna mungo, Aphrodisiac, Flavonoids, Testosterone, Sexual behavior INTRODUCTION Male infertility is a world-wide medical and social problem. In Homo sapiens, reproduction is initiated by the mating of a male with a female in sexual intercourse which facilitates the coming together of sperm and egg for the purpose of fertilization1. For there to be a normal sexual intercourse and sexual fulfillment in males, the male sexual organs (the copulatory organ, the penis) and factors relating to erection must function normally. Inability to perform this function effectively is a major problem facing the reproductive process. This is known as sexual dysfunction2.This condition which is of various types can be managed by the use of aphrodisiacs. An aphrodisiac can therefore be described as any substance that enhances sex drive or sexual pleasure. Aphrodisiac can also be viewed as any food, drug, scent or device that can arouse or increase sexual drive or libido3. Sexual dysfunction in men refers to repeated inability to achieve normal sexual intercourse. It can also be viewed as disorders that interfere with a full sexual response cycle. These disorders make it difficult for a person to enjoy or to have sexual intercourse. While sexual dysfunction rarely threatens physical health, it can take a heavy psychological toll, bringing on depression, anxiety, and debilitating feelings of inadequacy. Unfortunately, it is a problem often neglected by the health care team who strive more with the technical and more medically manageable aspects of the patient’s illness4.Sexual dysfunction is more prevalent in males than in females, It has been discovered that men between 17 and 96 years old could suffer sexual dysfunction as a result of psychological or physical health problems5. Male sexual dysfunction (MSD) could be caused by various factors. These include: psychological disorders (anxiety, strained relationship, depression, stress and guilt), androgen deficiencies (testosterone deficiency), chronic medical conditions (diabetes, hypertension, vascular insufficiency (atherosclerosis, venous leakage), neurological disorders (Parkinson’s disease, stroke, cerebral trauma, Alzheimer’s spinal cord or nerve injury), drugs (side effects) (anti-hypertensive’s, central agents, psychiatric medications, antiulcer, antidepressants, and anti-androgens), life style (chronic alcohol abuse, cigarette smoking), aging (decrease in hormonal level with age) and systemic diseases (cardiac, hepatic, renal pulmonary, cancer, metabolic, post-organ transplant)2,6,7. Vigna mungo most commonly known as Black gram or urad is an erect, fast-growing annual, herbaceous legume grows in many parts of India. It is extensively cultivated all over the India. The seeds are emollient, astringent, thermogenic, diuretic, aphrodisiac, nutritious, galactogauge, appetizer, laxative, styptic and nervine tonic. They are useful in treating scabies, leucoderma, gonorrhea, pains, epistaxis, piles, asthma, heart trouble, dyspepsia, anorexia, constipation, haemorrhoids, hepatopathy, neuropathy, schizophrenia, hysteria, nervous debility, partial paralysis, facial paralysis and weakness of memory. Seeds are believed as spermatopoetic, and used for treating erectile dysfunction and premature ejaculation8-11. In this regard, we undertook the present study on Vigna mungo which has been in use by the traditional healers. So far there is no systemic pharmacological study were carried out to investigate the aphrodisiac activity of vigna mungo seeds in male rats. Hence, the present study was aimed to demonstrate the aphrodisiac activity of different extracts of vigna mungo seeds. MATERIALS AND METHODS Collection of Plant material The dried seeds of Vigna mungo plant were procured from the local market of Hyderabad in telangana state. The seeds were authenticated by Dr. S. Madhav chetty, Associate Professor, Department of Botany, Sri Venkateswara University, Tirupathi, Andhra Pradesh, India. Procurement and Rearing of Experimental animals Healthy wistar Albino rats of both the sex (200-300 g) were procured from Albino Research Center, hyderabad. They were randomly housed in standard polypropylene cages and maintained under environmentally controlled room provided with a 12:12 h light/dark cycle approximately 25 ºC for 10days before the start of experiment12,13. They were fed with commercially available pellet diet obtained from Amruth foods, Pranav Agro Industries, Sangli, India and water was allowed ad libitum.The rats were acclimatized to laboratory conditions minimum one week prior to the experimentation. The study was performed as per the protocols and recommendation of the Institutional Animal Ethics Committee (Reg No:1662/PO/a/CPCSEA,2013) of Malla Reddy Institute of Pharmaceutical Sciences, Secunderabad. Preparation of plant Extract The dried seeds of Vigna mungo was powdered and subjected to soxhlet extraction with methanol, later the dried mark was subjected to soxhlet extraction with chloroform. Both extracts were concentrated by vacuum distillation and subjected to phytochemical screening. Experimental design Healthy and sexually experienced male albino rats (200– 300 g) that were showing brisk sexual activity were selected for the study. They were divided into 6 groups of 6 animals each and kept singly in separate cages during the experiment. Group 1 represented the control group, which received 10 ml/kg of distilled water orally. Group 2 served as standard and was given suspension of sildenafil citrate orally at the dose of 5 mg/kg, 1 h prior to the commencement of the experiment. Groups 3–6 received suspension of the methanolic and chloroform extracts of Vigna mungo seed orally at the doses of 200 and 400 mg/kg, respectively, daily for 21 days at 18:00 h. Since the male animals should not be tested in unfamiliar circumstances the animals were brought to the laboratory and exposed to dim light at the stipulated time of testing daily for 6 days before the experiment. The female animals were artificially brought into oestrus phase (as the female rats allow mating only during the estrus phase). They were administered suspension of ethinyl oestradiol orally at the dose of 100 ÃŽ ¼g/animal 48 h prior to the pairing plus progesterone injected subcutaneously, at the dose of 1 mg/animal 6 h before the experiment. The receptivity of the female animals was confirmed before the test by exposing them to male animals, other than the control, experimental and standard animals. The most receptive females were selected for the study. The experiment was carried out on the 21st day after commencement of the treatment of the male animals. The experiment was conducted at 20:00 h in the same laboratory and under the light of same intensity. The receptive f emale animals were introduced into the glass cages (40x50x40cm) of male animals with 1 female to 1 male ratio. The observation for sexual behaviour was immediately commenced and continued for first 2 mating series. The test was terminated if the male failed to evince sexual interest. If the female did not show receptivity she was replaced by another artificially warmed female. The following sexual behavioral parameters were recorded on audio video-cassette (Sony Handycam) as soon as they appeared14-17 Mount latency: Time duration (in seconds) from the introduction of the female into the cage till the first mount by the male. Intromission latency: Time duration (in seconds) from the introduction of the female into the cage till the first intromission by the male (vaginal penetration). Ejaculation latency: Time duration (in seconds) from the first intromission till ejaculation. Mount frequency:defined as the number of mounts without intromission from the time of introduction of the female until ejaculation. Intromission frequency: Total number of intromission preceding ejaculation. Ejaculation frequency: The number of times there was expulsion semen by males after vaginal penetration –characterized by rhythmic contraction of the posterior abdomen. Post-ejaculatory interval- is the time interval between ejaculation and the first intromission of the following series Determination of Serum Cholesterol and Testosterone: After recording of the sexual behavioral parameters, blood samples were collected from retro orbital plexus, centrifuged and serum was separated, samples stored at-200C which was used for the testosterone level estimation by using ELISA kit. Serum cholesterol concentrations may be determined by the Chod-PAP method18,19. Briefly, 0.02cm3 of the sample (serum) is mixed with 2.00cm3 of working reagent and the absorbance of the resulting mixture read after 5min at 546nm wavelength. The blank and standard are composed in a similar way except that they are replaced with 0.02cm3 each of distilled water and standard solution respectively. The biochemical estimations were done using respective kits. Statistical analysis The data obtained from this study were expressed as mean  ± SEM, (n=6). Statistical analysis was done by one way analysis of variance (ANOVA) followed by Dunnett’s test. P RESULTS The preliminary phytochemical screening of both the extracts revealed the presence of active constituents which includes alkaloids, flavonoids, tannins, saponins, phenols and steroids (table-1). The oral administration of two doses (200mg/kg, 400mg/kg) of methanolic and chloroform extracts of Vigna mungo seed resulted remarkable increase in sexual activity of the male rats. The results of the sexual behavior test shows that the extracts of vigna mungo seed (methanol and chloroform) at the dose of 200mg/kg and 400 mg/kg, significantly increased (pvigna muno seed.

Table 3: Effect of Methanolic and Chloroform seed extracts of Vigna mungo on testosterone concentration in male rats Values are expressed as mean  ± S.E.M.(n=6). a= P b = P DISCUSSION Male impotence or erectile dysfunction (ED) is a significant problem that may contribute to infertility. The incidence of erectile dysfunction, probably due to aging populations and other risk factor such as the presence of chronic illnesses (e.g. heart disease, hypertension and diabetes mellitus), smoking, stress, alcohol, drug abuse and sedentary lifestyles. A number of synthetic drugs are available for treating the infertility problems but because of their unwanted side effects folk remedies are gaining importance. Hence, the present study was carried out to investigate the aphrodisiac effects of methanolic and chloroform extracts of Vigna mungo seedin male rats. The preliminary phytochemical screening study of both the extracts revealed the presence of active constituents which includes alkaloids, flavonoids, tannins, saponins, phenols, and steroids. It has been reported that steroids and saponin constituents found in the many plants possess fertility potentiating properties, and useful in the treatment of impotence20. The saponins may therefore boost the level of testosterone in the body as well as trigger libido enhancing effect observed in this study21. The presence of flavonoids in the Vigna mungoextract which has been implicated to have a role in altering androgen levels may also be responsible for the enhanced male sexual behaviour in this study22. The alkaloids can also cause facilitation of sexual behaviour and has effect on sexual behaviour23. The improvement in sexual function demonstrated in the current study might be due to the presence of such compounds in Vigna mungoseed extracts. In the present study the sexual behavioral parameters were evaluated to estimate the potency of the Vigna mungo extract. In male rats mount latency and intromission latency are considered as indicators of the sexual motivation, where as intromission and ejaculation are considered as behavioural indication of sexual performance and facilitation24. There was a significant decrease in the latency for mount and intromission by the administration of various doses of seed extract of vigna mungo indicating an enhancing sexual motivation. The methanol and chloroform extracts have shown pronounced effect on sexual behavior by significant increase in mounting frequency (MF), intromission frequency (IF) as compared to control. Mounting frequency (MF) and intromission frequency (IF) are considered the indices of both libido and potency. Increase in these frequencies by the administration of the seed extracts might be due to increase in the concentration of several anterior pituitary hormones and serum testosterone, which in turn stimulated dopamine receptor synthesis and sexual behavior 25. Such increase in testosterone concentration should normally reflect a corresponding increase in libido 26.Hence, from these results the aphrodisiac effect of the plant extract may be due to the presence of alkaloids, saponins and flavonoids through a multitude of central and peripheral mechanisms. In the present study there is a significant increase serum cholesterol concentration which may imply stimulation in the steroid genesis, that leads to increased testosterone concentration27. Such increase in testosterone concentration should normally reflect a corresponding increase in libido26 . The present finding shows that the methanolic and chloroform seed extracts of vigna mungo produces a striking enhancement of over- all sexual performance of male rats. Our findings also showed that the aphrodisiac effect of vigna mungo seeds extract, investigated in male rats at 400 mg/kg, which significantly reduced ML, IL, EL and PEI with increased MF, IF and EF. CONCLUSION On the basis of our results the present study revealed that the methanolic and chloroform extracts of seeds of Vigna mungo showed the aphrodisiac activity and it is dose dependent in male rats. From this we conclude that the Vigna mungo seed extract may prove to be an effective and safe alternative remedy in sexual disorders. . 1

Affirmative Action Must Play a Role in College Admissions Essay

Anxiously awaiting its contents, the high school senior stares at his mailbox. He has been awaiting a response for months from his dream college. He has endured the endless questions from friends and family, "Did you hear from that college yet?" He has spent many a night he should have been sleeping lying in bed wondering whether he would be heading to his dream school in the fall. He has read numerous books and has done serious research on just what it took to get where he wanted to be. He continues to stare for hours, shaking from either anticipation or fear, though he cannot decide which. Finally his parents arrive home and encourage him to open the letter. He then opens the box. Now I ask this. Should this senior’s ethnicity impact whether his envelope is thin or thick? Should he have a better chance to attend his dream school because he is a minority? Or do the questions go deeper than the single factor of ethnicity? The issue of Affirmative Action, preferences towards persons of racial minorities to compensate for prior discrimination, in college admissions is a quite complicated one. Many sides must be explored to gain a better understanding of the theories and views on this issue. It is not easily answered with a yes or no. Since its inception, Affirmative Action’s use has been a major debate in American society. Many questions are left to be investigated. Many believe that we should live in a society where preferential treatment could be eliminated, and admission to college is based solely on one’s merit and character, yet this view seems quite unrealistic. The United States Supreme Court handed down its first decision on this complex issue with the case of Allan Bakke. Allan Bakke was a white male who applied to ... ...ns. The evidence supports the fact that if racial preferences are not used in admissions, the country will be withholding quality educations, both graduate and undergraduate, from large numbers of minority students. One of the staples of slavery when it is employed in this world is preventing those who are enslaved from becoming educated. We must work for the advancement of the human race as a whole, and this includes making sure that entire races of people are not left off prematurely on the road of education.

Sound in The Tempest and the New Orthodox View :: Tempest essays

Sound in The Tempest and the New Orthodox View  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Critics have offered varying evaluations of the characters in William Shakespeare's The Tempest. Some consider Prospero to be magnanimous for forgiving his enemies, for freeing Ariel from the confines of a tree, and for treating Caliban with great sympathy until the monster's attempted rape of Miranda. Others view Prospero as an oppressive colonizer and consider both Caliban and Ariel to be his innocent and mistreated subjects. In his article "Reading The Tempest," Russ McDonald argues that the new orthodox interpretation of The Tempest, "which exalts the colonized, is as narrow as the old, which idealizes and excuses the colonizer" (117). He argues that the actual status of the characters is considerably more ambiguous, and he supports his view by analyzing the rhetorical devices present in the play. However, a close examination of the various sounds disbursed throughout the work--including speech, silence, and music--tends to support a less ambiguous view of the characters. Indeed, it tends to lend support to the new orthodox view that Prospero is an oppressive colonizer, for he often threatens his enemies and servants with unpleasant sounds and demands silence from others, including his daughter. The play begins with a ship's crew being subject to terrifying sounds that Prospero has ordered Ariel to produce. The sounds are all loud: "whistle," "storm," "cry," "thunderclaps," "fire and cracks," and "roaring" (1.1.7, 14; 1.2.203-5; 2.1.2). The terror that these sounds and the accompanying storm inflict upon the mariners is evidenced by their cries: "All lost! To prayers! To prayers! All lost!" (1.1.52). The infliction of these sounds is also made to appear unjust when Miranda pleads with her father: "If . . . you have / Put these wild waters in this roar, allay them. / . . . O, the cry did knock / Against my very heart. Poor souls, they perished!" (2.1.1-9). Indeed, Prospero often refers to unpleasant sounds as a means of threatening others. "I will plague them all, / Even to roaring," he says of Caliban, Trinculo, and Stephano (4.1.188-214). When Prospero believes Ariel is not providing an eager and willful service, he threatens the spirit with imprisonment in a tree, reminding Ariel that when he was previously trapped, his "groans / Did make wolves howl" (1.2.289-90). Prospero also tells him, "Thou hast howled away twelve winters" (1.2.298). Similarly, Prospero threatens Caliban, carrying out his threats and subjecting the monster to tortures accompanied by unpleasant sounds.

Lies the Media Tells Us Chapter 3 Big Pharma

Going to the doctor’s office is never a fun experience. Probing, poking, and trying to decipher what the doc writes on your prescription can be confusing, however, the most upsetting part is what goes on behind closed doors. Big Pharma, chapter 3 of Lies the Media Tells Us, explains the PR tactics of drug companies. James Winter explains these tactics used to persuade doctors to use their brand. In some cases these doctors can get free vacations, cars, front row seating for a basketball game, and a stack of cash. The doctors that respond to these tactics are completely unethical. Doctors have the responsibility to prescribe the best drugs for their patients. Although many Doctors pick what gives the best gift package. Doctors have also been known to push drugs onto patients that may not really need it. This is due to the continual widening of guidelines. This widening is increasing proportions of the population so there are more candidates that fit into the category. This is when a condition gets called a disease. The best case scenario of this is Viagra. Viagra is for male sexual deficiency that has been shoved down America’s throat. There were many discrete commercials about it during day time air and more explicit commercials at night. There were also several celebrity endorsements, Hugh Hefner was glorified for being a user. What drug companies aim for are life-long medication users. These candidates are a gold mine for companies because they have created a dependency for the drug. Another highly publicized â€Å"disease† is high cholesterol. The Pfizer drug company has pushed their cholesterol pills for a decade now and all the marketing has worked. However, what they don’t tell you is that these pills run the risk of having more side effects than lowering cholesterol. By law these commercials need to state the side effects but when your being prescribed most doctors don’t dwell on these facts. This is wrong when there are better natural forms available. Although Doctors rarely discuss this with patients because these natural forms are very cheap or in some cases completely free. A healthy diet, naps, and some exercise are all examples of ways to lower cholesterol without taking prescribed pills. The push to take pills to help medical problems has completely consumed our country. In my opinion I feel that this correlates with the rise of plastic surgery. The easy way out is very popular among all ages because the time and effort that exercise or healthy diets needs is not necessary when pills and plastic surgery are in reach. These pharmaceutical companies adore patients that take their medicine and don’t ask questions. But what happens to the people that do? Not all doctors are shady and unethical. Nancy Olivieri and Dr. David Healy are true whistleblowers. Both have tried to get the medias attention to worn the public about unsafe drugs. Unfortunately, their good deed put them through heavy backlash and court cases. Olivieri and Healy saw their colleagues turn their backs on them and were fired. This is a tough price to pay when they were trying to do the right thing. Pharmaceutical companies can get away with all of this because they have the money. They pay off whistleblowers, they perform under the table deals with doctors, have multi-million dollar campaign ads for their drugs, and have celebrity endorsers. Although these tactics are very unethical there is one more that upset me the most. This is ghostwriting. Ghostwriting is a doctor that works for the drug company and writes an article for a drug that gets published in a medical journal. Lots of doctors write for medical journals but what separates them is their lack of honesty. These ghostwriters don’t say their affiliated with the pharmaceutical and praise the drug that the company wants to endorse. When these companies get articles published about their drug its free advertising. So when other doctors read the article their actually looking at an advertisement but they don’t know it. These medical journals are supposed to be unbiased and legitimate. This is undermining why these medical journals are published and taken so seriously. In my opinion this is the worst thing a pharmaceutical company can do. PR is a huge branch within the pharmaceutical company and they all have about the same strategies when a drug scandal breaks. I feel that this is crucial to why these companies have gotten away with so much. Their first tactic is denial. Like a child they deny everything and have accused the media of sensationalism and attack their accuracy of reporting. If the scandal doesn’t dissipate after they have three different options. First they could shutdown, this consists of claiming their is a conspiracy. Second option is an extrication which is hiring high priced lawyers to find an escape route or third which is purging. Purging is very interesting because they basically pick an employee in their own company, pay them to take the rap, and then tell everyone it was the employees fault. Most of the time they try to get someone that is going to retire; I guess everyone has a price. The last option of the pharm co. is the most used. This is the compensation tactic. The drug company offers the plaintiff a large settlement as long as the plaintiff agrees there was no malpractice. This corrupt business isn’t that big of a shock. Where ever their is a lot of money there is usually some unethical practices. However, I feel that their money has way too much control. Their funds are practically endless and they will come up with any lie to make more money. After reading this chapter I thought about Obama’s healthcare reform. I think the reason why their is so much backlash is because the pharmaceutical companies are scared about the future and if they will be able to keep these shenanigans going. I like the idea of Obama’s healthcare but I know that these companies will weasel their unethical views into it. Honestly, I don’t think there is anyway to stop this unless everyone working for these companies is fired and it is started back up from scratch.

Wireless network routing on linux

1. IntroductionIn this portion of the topic, we are traveling to look at the introductory facets of sphere name waiters and its construction and its functionality facets. In which we are traveling to larn about several distinguishable routing mechanisms that helps us to implement dynamic routing with its organisation. In this we are besides traveling to larn about how to get down the routing between the terminuss and routing between groups and so on. In this portion we will show about the chief thought on smaller way routing and multicasting in routing so on.1.1 AIM AND OBJECTIVEThe chief facet that lie beneath the debut of webs operation inside the house by Unix Router is studied, at the same time with the adversities that occur during development and constellation of router for the house and when all the workers uses the Unix OS. The chief facet that lie beneath the debut of webs operation inside the house by Linux Virtual LANS is studied, at the same time with the adversities that occur during development and constellation of router for the house and when all the workers uses the Mac OS. This technique besides concerns about the presentation mechanisms for doing certain a grow able and resilient web group development using the Unix Router. [ 1 ] Coming to the routing in Linux from local system to remote nodes within the web there are two distinguishable types of attacks and they are based on use of routing statically or dynamically. Each type of the attack that the router follows has some benefits and drawbacks besides in it, but when a web increases its capacity so dynamic routing is the most low-cost manner of keeping the web in Linux. Taking this facet into consideration we have to happen out the use of dynamic routing protocols in the topographic point of the use of inactive waies in all terminuss of a web2. Introduction ON SUBJECTIn this portion of the topic, we are traveling to look at the introductory facets of sphere name waiters and its construction and its functionality facets. In which we are traveling to larn about several distinguishable routing mechanisms that helps us to implement dynamic routing with its organisation. In this we are besides traveling to larn about how to get down the routing between the termi nuss and routing between groups and so on. In this portion we will show about the chief thought on smaller way routing and multicasting in routing so on.2.1 DOMAIN NAME SERVERThe Domain name waiter construction on the cyberspace really works like this: There are machines that work on petition of IP Numberss of these itself. These machines are known as waiters on sphere Name Server, and a petition is known as a Domain Name Server Lookup. Every Domain Name Server merely has inside informations about a specific entity of the universe broad web, and they often contact each other. [ 2 ]2.2 DIFFERENT ROUTING TECHNIQUESThere are several different attacks that exist and which help us to implement dynamic routing inside the IT organisation.Zebra is a codification for Linux machines which can keep several of the protocols demonstrated in this thesis. It is TCP/IP routing package that works with, OSPFVS RIPv1 and RIPv2.Gated is one more functionality plan for Linux, but it works merely in its binary province. This attack has a higher period of heritage than zebra and could be much faster. High terminal version of this attack works, but merely with proper licences in the market. Educational establishments works with this attack in different ma nner.Routed is a basic attack that is best available attack based on its cost restraints on Linux platforms. It is restricted merely to utilize a RIP protocol, which non a best option to travel on in a large webs, particularly when the web grows invariably. This is significantly advantageous for little webs. Merely thing we have take into consideration is the suited version of routing which works with RIP.2 and therefore we can work with class-less webs.The use of dynamic routing protocols is non that of import, but it is optional. A inactive Linux way can be another suited option to fall in the web to different node.2.3 ROUTING AMONG NODESWhen we join nodes combined with a distinguishable assortment of IP references will be used to those of set ‘s client web in Linux. The connection can be established between merely two-terminals as a point-to-point connections between the terminuss, but in instances where many terminuss can pass on with each other the terminuss can be config ured to be inside a basic country web, hence giving permission to them to pass on information in much better manner and forestall the hops. [ 2 ] The IP references used for the inter-terminal connection will be from the set 192.168.1xx.y, get downing with 172.168.64.0 and traveling on with 172.168.64.4, 172.168.64.8, depending on the measure of connections used. This could be the instance in point-to-point connections. In this instance 255.255.255.252 will be the net mask and will include two good IP addresses one for every terminal of the terminus. For bigger webs a bigger web will be marked for utilizing the suited net mask in Unix Router. To the several figure of webs which will, which may be predicted to be within a routing set the routing between the terminuss can be a hard undertaking. To decide this restraint it will be more frequently be necessary to use a interior gateway protocol, like RIP-Routing information Protocol or OSPF-open shortest way foremost, the protocol will be a much hard attack but confronting a adversity job. If the set ‘s web comprises of a less figure of terminuss inactive routing can be adjustable option, although it is non a coveted one. The use of dynamic routing in Linux prevents manual changes and makes certain that the connection to the new terminuss on the web commences automatically in a normal manner. For these peculiar facets its benefits are demonstrated whenever possible. Due to these facets antecedently the client IP addresses, and the use of the IP references choose for fall ining the terminuss within a Wi-Fi set must non be against with the references used by other Wi-Fi sets. Chiefly based on this aspect each set should hold to register the IP which has to be used for inter-terminal connections if they are distinguishable to the IP references used by their clients. If this is non made, it may non back up the routing between client terminuss on both webs joined to the Linux router, but it will do rectifying routing troubles ne'er possible which taking opportunities to larn about flow from one web to the other, and this is non at wholly opted to utilize. It is easier to unite protocols on the same web this is non a best suitable attack as the routing traffic will maximise and besides there will more hard adversities in the machines which should reassign the routing related informations from one protocol to another protocol within the web. Therefore every router sets must seek to judge on the routing and take a opportunity and must be certain that all routing inside the web between terminuss utilizes this similar protocol in Linux. As it could non be a desirable option to swear each one inside the web it may be compulsory for the terminuss admin to maintain some preventative confirmation techniques to do certain that incorrect informations related to routing is non inserted into the web.2.4 ROUTING WITH OTHER GROUPSEach clip a connection occurs by a web set to an outside machine is stated, in other territories, states or countries it is high precedence to do certain that there are no job between the different IP references used by the sets, and that no other high precedence restraints are traveling to be taken topographic point. [ 6 ] A web set an utilize the similar ways of interior gateway protocols to reassign routing related informations with other set as it happens within the nodes, but is more frequently desirable to use an exterior gateway protocol. Routing with another web sets must more frequently be made utilizing the boundary line gateway protocol and this is a peculiar 1 for which it is necessary to heighten more acquisition. The benefit of this technique is that every machine or set of machines in the web is termed as an chief machine which operates automatically and there is necessity to hold the inside informations of group ‘s internal paths, merely the places of entree to the set, the webs it comprises and the connection it has to other groups. [ 7 ] The assortment of IP references used for the inter-set interlinking is described antecedently and the references used must be made public to forestall IP reference jobs inside the web by the router. Taking into consideration of this, T may non be possible to wholly swear all the related informations gained by another set ‘s in the web and at the same clip to forestall erroneous informations being inserted into the web it may be of import for the web admin to maintain necessary confirmation techniques to do certain that false routing related informations will non oppositely affect the set ‘s web right methodological analysis. In a web set in the Linux we are said that a machine which operates automatically is necessary to give a figure utilizing some peculiar codification which specifically makes it out. In several state of affairss the set will non hold its single AS figure. It is said that when a set requires a new AS figure that it meets the Wi-Fi sets and it must be given with a figure inside the private AS group referred by RFC 1940. This set of Numberss is from 6441.2-65564. It will be good if a record of the given AS Numberss used by the Wi-Fi sets is placed in a public location web site such that it can be viewed and taken as mention by the distinguishable web sets. The existent AS figure is non that necessary, it is fundamentally an AS figure which is used for designation. In the similar mode that it is of high precedence that the IP references used by united work sets are non made extra transcripts, it is besides necessary to look into that a new set does n't utilize a As figure given to other work set, due to which the routers may be falsely communicated up to a certain extent.2.5 OPEN SHORTEST PATH FIRSTOpen shortest way foremost is a non important link- province routing protocol. Open shortest way foremost can be used as an unfastened beginning and is said to be robust attack because it works on a broad scope of platforms independently which may be supplying this sort of support to the web and as it is a link-state protocol it can be distinguished from RIP or IGRP which are distance-vector protocols. Open shortest way foremost will non ever reassign a record of all its paths to its environing 1s, but merely transfers the alterations it finds out in the web construction, hence forestalling the non needed use of webs bandwidth. This is extremely more good than distance-vector algorithms which rely on the given timers to reassign sometimes local routing related informations to the staying web. Using the unfastened shortest way foremost the junction clip when a web alters may be every bit little as five or six seconds, which in the instance of RIP is hundred and ninety seconds. The naming of the routers which make an unfastened shortest way first web are given a peculiar name base on some facets like topographic point and necessity of them inside the web. About which it is demonstrated below briefly:Internal Router:Internal Router is a router in which all the webs are joined inside the same country in a direct manner. In the Internal Router merely one transcript of routing algorithm will be continued.Area Border Router:Area boundary line Router is a router in which it joins country to an country. It makes ideas between the two countries and maintains the webs which are utilized between them.Back Bone Routers:Back Bone Routers are routers which are the related to country O and are the necessary 1s for the broadcast medium through webs between several distinguishable countries.AUTONOMOUS SYSTEM BOUNDARY Routers:Autonomous system boundary routers are routers which are joined to the other AS or to the worldwide web. These are specifically routers which broadcas t routing related informations with other IGP and EGP routers which need non utilize the unfastened shortest way foremost. There are several distinguishable ways in which we can fall in the countries or terminuss at eh routing phase in web. A VPN manner has besides been introduced which can be extremely advantageous, specifically while fall ining distinguishable webs among territories or while the two terminuss are fare separated and it is mandatory to set up a nexus over the universe broad web. In this attack we can propose the country O is been placed as the chief terminus and more likely to a big bandwidth cyberspace connexion and to which other webs may be joined. In the instance where the terminuss many non be joined in direct contact to country O utilizing a direct contact or by VPN a practical connection to fall in it to country O will be necessary.2.6 OPEN SHORTEST PATH FIRST COMPARED TO OTHER PROTOCOLSThere will be peculiar instances in which peculiar machines will non assist out unfastened shortest way foremost and in this state of affairs another protocol such as RIP can be used, till it is RIP version 2, or lake herrings EIGRP two of which helps instance less webs. On a whole, the ABR will necessitate to assist open shortest way foremost to do certain that it need non give out the entire web related informations. It is required at the clip the entire web are joined to use protocols which can exemplify brief versions of the webs within an independent system as this will minimise up to a certain extent the use of the sum of routing related informations which is necessary to be exchanged between several distinguishable routers.2.7 BORDER GATEWAY PROTOCOLThe of import facets of the boundary line Gateway Protocol is same to that of an IGP router like unfastened shortest way foremost which surveies the minimal paths to entree the remaining of the terminuss and webs inside a machine which operates automatically. This differentiation is because of the Border Gateway Protocol works with webs of several distinguishable machines, exemplifying its ain web and happening out the ways by which the staying independent machines can be attained. BGP besides has several filtrating techniques which gives entree to us to take a determination to give a presentment to each of its bordering webs or non to inform related to the several distinguishable webs to which they are joined Because of the above facet, the benefits of BGP is considered as significantly advantageous to bury joint distinguishable Wi-Fi webs, as another option of utilizing an IGP type unfastened shortest way foremost.2.8 SUPPORT FOR MULTICAST ROUTINGSupport for multicast references must be involved in the terminuss routers, as this will give entree for systems which utilize the bandwidth of the web to a maximal extent. It keeps it conformity with multicast references that it is used to a maximal extent by several runing systems, but package sweetenings are compulsory for support multicast routing. For building a inactive routing tabular array, even we have an optional routing tabular array which maps to link hosts merely on the physical webs which are connected straight. The paths by the outside gateways must be included to the routing tabular array. One types of method to back up this edifice a inactive routing tabular array with path questions. In the routing tabular array, we can utilize manually route question to infix or cancel entries. To explicate the more clearly, if we wanted the path 207.25.98.0 to be added to a Solaris machines routing tabular array with path questions, so types: â€Å" # path add 207.25.98.0 172.16.12.11 add net 207.25.98.0: gateway almond† . As it is considered as a first bid after the path in this illustration is the cardinal guard ‘s add-on. The keyword on a interpolation or omission, commanding path to infix a new path or to cancel a present one. On the other manus, other value must be derived as finish references, which has to be assumed as reference that is attained through the path. At the same clip, Network name from the webs file as an Ip reference the mark reference could be assigned, a host name from the host files or the keyword fundamentally. Several Linux paths are inserted at the beginning degrees, IP addresses which are numeral are used more than the machine names. This is made for back uping that the routing scheme is independent on the degree of the name waiter package. At any clip we must use the entire numeral reference ( all 4 bytes ) . The path enhances the reference if it is made up of smaller than four bytes, and the enhanced reference need non be the one which we desired. If the basic keyword is used for the mark reference, path establishes a basic path. The basic path to a finish and it is fundamentally the one router we need in the web, if the web of ours has merely a individual gateway, and so use a basic path to convey all the traffic that is related to the distant webs through that gateway. The path question twine is the gateway reference for the web. It utilizes the IP reference of the outside gateway by which information is transmitted to the mark reference inside the web. The reference should hold gateway reference which is joined through a direct nexus in the web. The following hop must be available to the local host through a direct nexus. Therefore, it should be on a web which is joined straight. The metric bid is non used when routers are removed, but assorted machines need it when a path is inserted. Although its demand is necessary, path utilizes the metric merely to judge if this is a path which is attained by an interface through a direct nexus or a path that is achieved by a outside gateway. If the metric is O, the path is implemented as a path by a local interface, and the G flag. However, the gateway reference has to be considered with the aid of G flag set If the metric is more than zero, the reference should be assigned address of outside gateway.2.9 ADDING STATIC ROUTESTo infix inactive router in Linux atmosphere the subnet value 172.16.12.0. There are fundamentally two gateways on this subnet that can be handled, and they are almond and pecan. Almond type of gateway is utilized to several of the webs on the cyberspace used in Linux. Whereas the pecan gives entree to the different subnets on nuts-net therefore, We can use Prunus dulcis as our basic gateway due to i ts use of several 1000s of the paths. The lesser figure of paths that can be accessed with a easiness clearly by the pecan. The figure of paths that are accessed by a gateway waiter is non the measure of traffic it maintains, but Judgess which gateway to take as a basic one.To put in the default path on peanut, we enter:# path -n add default 172.16.12.1 1, add net default: gateway 172.16.12.1The mark is usually set as default ; Prunus dulcis ‘s reference is nil but the gateway reference ( 172.16.12.1 ) . The -n keyword is non a necessary option in Linux. It is merely to give the informations related to the path to demo numeral references in its informations messages. When we insert router questions to a startup file, use the -n keyword to avoid way from dissipate clip frame from commanding name waiter package that might non be put to deathing. After implementing the default way, measure the routing tabular array to guarantee that path has been inserted:% netstat -rnRouting Tables:FinishGatewayFlagsHoloceneUseInterface127.0.0.1127.0.0.1UH1132LionDefault172.16.12.1UG00Lion172.16.12.0172.16.12.2Uracil2649041LionBeginning: hypertext transfer protocol: //docstore.mik.ua/orelly/networking/tcpip/ch07_03.htm Attempt ping one time to look into the peanut is now ready to interchange informations with distant hosts. If we are fortunate, the distant host will reply and which will wish this: It is likely that the distant host is crashed or dropped. If it is, the Ping does non react. If it is like this we should non lose our hopes ; we need to seek another waiter.% ping 207.25.98.2 Ping 207.25.98.2: 56 informations bytes 64 bytes from the ruby.ora.com ( 207.25.98.2 ) : icmp_seq=0. time=110.

On the other manus, now besides we have non implemented paths to the left over nuts-net. If we ping a host on different subnet, something exiting occurs:— – % ping 172.16.1.2 — – Ping 172.16.1.2: 56 informations bytes ICMP Host redirect from gateway almond.nuts.com ( 172.16.12.1 ) to pecan.nuts.com ( 172.16.12.3 ) for filbert.nuts.com ( 172.16.1.2 ) 64 bytes from filbert.nuts.com ( 172.16.1.2 ) : icmp_seq=1. time=30.

Hence, even information meant for some other subnets is transmitted to almond. If insignificant transmits information to almond that must travel through the pecan, almond transmits an ICMP Redirect to peanut desiring it to utilize pecan Ping illustrations the ICMP Redirect in action. Netstat shows the consequence the redirect has on the routing tabular array:% netstat -nrRouting TablesFinishGatewayFlagsRefcntUseInterface127.0.0.1127.0.0.1UH11604lo0172.16.1.2172.16.1.3UGHD0514le0Default172.16.1.1UG3373964Lion172.16.1.0172.16.12.1Uracil686547686547le0 Beginning: hypertext transfer protocol: //docstore.mik.ua/orelly/networking/tcpip/ch07_03.htm The path with the D flag set was installed by the ICMP Redirect. Some of the web directors take the benefit of ICMP Redirects while intriguing and developing a web. All hosts are implemented with a default way, even those on webs with more than one gateway. The gateways swap routing informations through routing protocols and readdress hosts to the finest gateway for a specific path. This sort of routing, which is necessary on ICMP Redirects, has been a important attack due to personal systems ( Personal computers ) . Assorted Personal computers does non put to death a routing protocol ; some does non hold a path question and are restricted to a lone default way. Obviously, ICMP Redirects are delighting to keep up these users. Along with this, this sort of routing is simple to implement and best appropriate for execution by a constellation waiter, as the similar default way is used on each host. Based on these facets, some web directors support confidence on repeating ICMP Redirects. [ 6 ] Additional web decision makers want to forestall ICMP Redirects and to continue direct bid of above the topics of the routing tabular array. To remain off from redirects, specific paths can be setup for each subnet, utilizing independent path statements:# path -n add 172.16.1.0 172.16.12.3 1, add net 172.16.1.0: gateway 172.16.12.3 # path -n add 172.16.6.0 172.16.12.3 1 add net 172.16.6.0: gateway 172.16.12.3 # path -n add 172.16.3.0 172.16.12.3 1 add net 172.16.3.0: gateway 172.16.12.3 # path -n add 172.16.9.0 172.16.12.3 1 add net 172.16.9.0: gateway 172.16.12.3 Netstat shows what the completed routing table expressions like. % netstat -rnhypertext transfer protocol: //docstore.mik.ua/orelly/networking/tcpip/ch07_03.htm Routing tabular arraiesFinishGatewayFlagsRefcntUseInterface127.0.0.1127.0.0.1UH1132Loe172.16.12.0172.16.12.2Uracil2649041Lion172.16.1.3172.16.12.3UGHD1514LionDefault172.16.12.1UG00Lion172.16.1.0172.16.12.3UG14904Lion172.16.6.0172.16.12.3UG00Lion172.16.3.0172.16.12.3UG00Lion00LionBeginning: hypertext transfer protocol: //docstore.mik.ua/orelly/networking/tcpip/ch07_03.htm The routing tabular array we have created utilizes the default way i.e. by Prunus dulcis to achieve outside webs, and specific waies by pecan to achieve other subnets inside nuts-net. Re-executing the Ping options facilitates regular most achieving end products. On the other manus, if any subnets are excess to the web, the waies to these new subnets should be manually inserted to the routing tabular array. On a whole, if the machine is restarted, all routing tabular arraies which are inactive will lose its entries. Hence, to use inactive routing, we should guarantee that the waies are re-introduced every clip our machine restarts.Installing inactive paths at startupIf we make a determination to use inactive routing, we need to make two changes to our startup files: Insert the wanted path statements to a startup file. Delete any statements from startup file that execute a routing protocol. Linux offers an inspiring illustration, due to its demand of inactive paths to build the optimum routing tabular array. The Linux debut of ifconfig will non change the routing tabular array when a new interface is implemented. The way for a new interface is inserted form outside with a path question. These interface paths are stocked up in the startup book. The chief path statements in rc.inet1 utilize book variables. We altered these to references for the intent of ambiguity./sbin/route add -net 127.0.0.0 /sbin/route add -net 172.16.5.0 netmask 255.255.255.0beginning: hypertext transfer protocol: //docstore.mik.ua/orelly/networking/tcpip/ch07_03.htm The first statement installs the path for the loopback interface. Taking into consideration of this brief sentence structure of this codification: it find out a mark but no gateway. This is due to Linux has a specific sentence structure merely for including a path to an interface. We must hold stated the bid as: /sbin/route add -net 127.0.0.0 dev lo0 If dev is non mentioned on the codification line, the way codification finds out the right interface from the mark reference. The 2nd statement from /etc/rc.d/rc.inet1 book implements the way for the Ethernet interface. This statement comprises of a subnet mask. If nil provided, it would default to 255.255.0.0, which is the criterion for category B reference 172.16.0.0. Implementing waies for straight presenting interfaces is specific to Linux. On a Solaris system, edit /etc/init.d/inetinit to add the path statements:path -n add default 172.16.12.1 1 & gt ; /dev/consolepath -n add 172.16.1.0 172.16.12.3 1 & gt ; /dev/consolepath -n add 172.16.3.0 172.16.12.3 1 & gt ; /dev/consoleBeginning: hypertext transfer protocol: //docstore.mik.ua/orelly/networking/tcpip/ch07_03.htm3 INFORMATION SECURITIESNetwork security and informations security are largely used as the security mechanisms which are maintained one or the other. On a whole web security is usually taken in to consideration for security mechanisms at the terminals of a house, seting out the unauthenticated entries, for illustration Data Loss Prevention-DLP. In the instance of the two manner attack of hallmark, the things which we utilize are the things which are in usage, coming to the three manner attack of hallmark the things which we have used are besides used. A important survey of basic techniques and inside informations in web security is demonstrated in the signifier of a non sum topology of web security onslaughts. [ 14 ]3.1 SECURITY MANAGEMENTSecurity direction for webs is varied for all types of scenarios. Manageability enhances package and hardware to forestall boisterous charges from speaking entree of the web and spamming. A switch works as a several-port span and to larn the topographic point of each systems Mac reference by maintaining an oculus on the current traffic. For each clip period it switches, it will merely travel in front traffic to the port that contain the finish Mac reference. Developing switched LAN internet maps for the 30 five staff several of which are included in the papers development, interaction with clients and disposal of office.3.2 PERSONAL LEGAL TEAMPreviously, the web developers and router had merely a minimal ways of taking the hardware tools at the clip of purchasing a engineering for their organisation webs. Hubs are by and large used for wiring cupboards and routers which are responsible for information centre or important communications operation.3.3 BUSINESS LEGAL TEAMIn the instance of concern legal squad staff and legal workers, maestro in marketing Torahs. Function of LAN exchanging and UNIX router engineering in organisation web Several web developers are get downing to present shift tools into their present running shared-media webs to achieve the illustrated aims: Involve the maintainability of VLANs by structuring web clients into logical work sets that are non dependent of the physical topology of wiring cupboard hubs. This could cut down the disbursals of alterations, interpolations and alterations while maximising the easiness of usage of the webs. Shared-media LANs separates the clients into two or more independent LAN units, minimising the figure of clients that are in conflict for bandwidth. LAN exchanging technique, which constructs this attack, involves micro divider, which besides partitions the LAN to lesser clients and eventually a lone client with a changeless regular LAN unit. Switch overing technique is the best opted coveted solution for heightening LAN traffic for the so called facets.Not like hubs and repeaters, a switch provides many informations watercourses to reassign at a clip.Switchs by the micro divider ways, have the capacity to manage maximized gait and bandwidth of turning engineeringsSwitched cyberspace and UNIX router solutionsNetwork developers have observed that assorted systems which facilitate switched cyberspace and UNIX router work solutions are really few. Some provide a restricted figure of hardware platforms back uping little or no machine execution with the present substructure. To be signifi cantly advantageous, a switched cyberspace work solution should achieve the followers:Control strategic influxs in the present communicating substructure which maximising come-at-able bandwidth.Reduce the disbursals of keeping web operations.Provide ways to assist multimedia plans and other most-demanded traffic in between a broad scope of platforms.Attain scalability, traffic ordinance and security to minimum extent up to the present twenty-four hours ‘s router-related internetworks.Achieve a assisting manus for built-in distant monitoring- RMON entity.The chief attack to achieving these is to recognize the functionality of interworking package mechanism inside the switched inter webs. Though LAN and ATM switches are demoing good sweetenings in the functionality facets, they give manner to the new internetworking challenges. Therefore a existent switched internetwork in more important than a group of boxes. It comprises of a machine of devices follow and worked by an internet working package technique. With the innovation of switched interworks, the expertness will be displayed on the whole of the web, demoing out the non centered facet of exchanging systems. The necessity for an internetworking substructure will be in a similar manner.4. COMPONETS OF SWTICHED INTERNETWORKING MODELA switched internetwork is comprised of chiefly three important tools which are: physical shift platforms, a common package substructure, web direction tools and applications, web developers with a entire terminal-to-terminal solution for presenting and keeping sweetening belongingss, robust, switched internetworks4.1 SCALABLE Switch PLATFORMS4.1.1 EVALUATE IPV4 AND IPV6 FOR THE STAFFIPv6 security is similar to that IPv4 security in assorted attacks. In truth the similar adversities that occur IPv6 1Psec execution IPv6 is usually implemented without the necessity of cryptanalytic security of any type. Along with this, due to several security restraints that are faced at the application degree, even the important execution of 1Psec with IPv6 will non supply any farther security sweetening for those onslaughts Inspite of the advantageous capableness of happening out the ground of the onslaught. There are some of import differentiations between IPv4 and IPv6, out of the authorization of 1Psec. These distinguishable facets will change the sorts of onslaughts which IPv6 webs are largely to face. It is besides non normal that the optimum house will alter wholly to IPv6 in a little clip period ; it will largely pull off IPv4 fall ining for the whole of multiyear migration to IPv6. At present, this has non a proper solution for the onslaughts which those type webs will confront and the development alterations necessary to turn to those onslaughts. This gives a brief of several of the basic onslaughts towards IPv4 and so evaluates and contradicts how these onslaughts or 1s that resemble like these might impact an IPv6 web.4.1.2 THIS DOCUMENT BENEFITS THE FOLLOWING GROUP OF INDIVIDUALSNetwork and security designers: – This broad association of people are the chief behind the building of the universe broad web at present and has restrictions for peculiar states, chiefly which are non involved in the IPv6 protocol and its alterations.Security research workers: – By taking into consideration of this thesis they must expertise with solutions for research in IPv6 security.IETF members: – The IETF, this association is the necessary 1 for the growing and sweetening of the IP Protocol, must be advantageous from a comparative survey of the deficiencies in IPv4 as in contrast to IPv6.Government Policy shapers: – The US section of defence has made out its thoughts a complete displacement to IPv6 by 2008, confused a spot by its aim for security. This purpose is appreciatable, but IPv6 is non a solution for all security concerns on a whole, a valid portion of influxs in the growing of new research stuffs for authorities workers is necessary demand to necessitate the end with in 2008.Other associations within the authorities have concerned on IPv6 as a manner of sweetening in worldwide wed security. This thesis is considered to be a helpful reso urce for such association for indicating out instances where there is a demand of attending. This engineering, IPv6 geographic expedition is varied from the IPv6 in two chief facets. The first is that the ping expanse or port scan, when used to measure the hosts on a subnet, are considerable difficult to carry through in IPv6 web. The 2nd, new multicast references in IPv6 gives out a manner to pick out specific set of cardinal machines with easiness. Additionally, go forthing these separating characteristics, geographic expedition methods in IPv6 are the similar 1s when compared with IPv4. IPv6 are besides more dependent on ICMPv6 to work decently. Strong filtering of ICMPv6 may go forth sick effects on web methods.5.1 NETWORK MANAGEMENT TOOLS AND APPLICATIONSThe units of a switched internetworking theoretical account is comprised of web maintain tools and applications. A important switched internetworking method should include the advantages of routers and switches together in each portion of the web, along with this it should supply a easiness of usage mechanism from shared-media networking to exchange internetworks. In normal switches which are non collaborating in the organisation web development gives out the undermentioned advantages: Large bandwidth, quality of service, less expensive, Time frame, Ease of constellation is high precedence facet and appraisal disbursals.5.2 comparings of LAN switches and routers:Routers provide the undermentioned maps:Conveying firewall, Communication between distinguishable LANs, Convergence in less clip, Policy routing, Security, Load rating and Idleness, Traffic transportation care and multimedia association rank.5.2.1SUBNETWORKINGEasy to entree switched internet maps are comprised of physically distinguishable dividers, but are logically taught to be as a one individual web. This facet is included to the me thod that LAN switches operate- they regulate at OSI layer2 and must supply connectivity to hosts as if every host is located on a individual overseas telegram. Layer 2 turn toing considers a level reference infinite with broad assortment and scope of particular references. Routers regulate at bed 3, evaluate and stick to a hierarchal addressing construction. Route webs can associate a logical addressing method to a physical substructure so every web divider substructure so every web divider has a TCP/IP subnet or IPX web. Traffic transmittal on routed webs is distinguishable from that is on switched webs. Routed webs have more flexible traffic transmittal as they utilize the hierarchy to indicate out minimum paths based on dynamic facet Such as web concern. Datas can be gained by the staff to routers and switches that can be used to set up maximal unafraid webs. LAN switches may use created filters to supply entree control depending on mark reference, beginning reference, protocol sort, package size, and inside the clip frame. Routers can filtrate on logical web references and supply a regulative depending on facets accessible in layer 3 or halt traffic depending on specific TCP/IP socket related informations for a set web references.5.3 BENEFITS OF LAN SWITCHESAn independent bed 2 switch may supply some or all of the illustrated advantages:Bandwidth: – Local area network switches provide important growing and sweetenings for single clients by giving specific bandwidth to each switch port ( for illustration, each web divider ) . This method of allotment is called Micro divider.VLANs- LAN switches can organize a set of independent ports into logical switched work sets termed as VLANs hence ; by this they restrict the transmission sphere to valid VLAN member ports. VLANs are besides called as switched spheres and independent shift spheres. Transmission between VLANs needs a router.5.4 NETWORK DESIGN PRINCIPLESSignificant web development is dependent on assorted surveies that are illustrated in brief based on the chief facets described below:Examine individual points of failure carefully: There must be a minimizing manner in the web so that a lone malfunction will non halt any portion of the web. There are two cardinal characteristics of minimising that are load equilibrating. In the instance of a malfunction in the web, there must be a alternate path. Load equilibrating happens when two more paths to a mark are present and can be used based on the web burden. The degree of minimising technique required in a specific web differs from web to web.Characterize application and protocol traffic: Taking into consideration, the transmittal of plan information will sketch the client-server exchange of informations and is of import facet for important resource allotment, like the figure of users utilizing a specific waiter or the figure of user a specific waiter or the figure of user workgroups on a divider.Analyze bandwidth handiness: – Taking into consideration, the must non be order of measure differentiation between the several distinguishable sorts of the hierarchal theoretical account. It is critical to take a note that the hierarchal theoretical account relates to knowledge beds that provide functionality. The bandwidth return provide functionality. The bandwidth takes important part in the topology where a big figure of Stationss are at that place. The beds need non hold to be a physical connection it can be the anchor of a specific device.Build webs using a hierarchal or modular theoretical account:The hierarchy gives manner to independent dividers to go the yesteryear of cyberspace and map together. In the individual router layout, the chief and distribution beds are included in a individual unit. The router chief functionality is shown by the backplane of the router and distribution is shown by the router. Permission allowing for terminal clients is achieved by independent or chassis-based hubs. The distributed anchor construction utilizes a really fast anchor media, usually FDDI to convey routing engineering between several routers. This besides makes the anchor to go across floors, a flat or an organisation. Switched LAN web design rules: When developing switched LAN organisation webs, the assorted facets that are to taken into history are described below:Accessible bandwidth to entree routing functionality: Inter-VLAN traffic should be routed, by which the web development will give sufficient bandwidth to several inter-VLAN traffic from the beginning, by the machine that affords routing methodological analysis and to the mark.Appropriate arrangement of administrative boundaries: Switch has the possibility of agony of multiport webs and the execution of exchanging external of our administrative bounds can oppositely had to enduring the webs inside our administrative bounds. Organization web development are heightening significantly with the execution of exchanging at all degrees of the web from desktop to the anchor. Three topologies have been come out as generic web development techniques: scaled shift, big shift, minimum routing, distributed routing, shift, and scaled shift.To mensurate the upper limit switched, min imum routing design, a logical hierarchy should be implemented. The logical hierarchy comprises of VLANs and routers that facilitate inter-VLAN broadcast medium. In this topology, routing is used merely in the distribution bed and the entree bed based on bandwidth by the distribution bed to achieve permission to really fast exchanging methodological analysis in the major bed.Chapter 6The information mentioned in this chapter illustrates us the research techniques that I have used for theUracilnothings based router.6.1 Research Methodology6.1.1 LAN and Router planing for an organisation and scenarioA organisation which have hundred and 50 worker, five staff are related to the betterment of the selling state of affairs. The IP web development series speaks about the concern related with organisation LAN development. The selling technique related on the footing of searchnetworking.com, tells the advantages of concern by Ethernet exchanging in contrast to the traditional hub ambiance. The chief nonsubjective beneath the execution networking inside the house is by practical LANs is seen besides with the facets related to the characteristics like gauging and constellation of router for the house and all the workers are utilizing the MAC OS. This thought besides illustrates for doing certain a adjustable and resilient organisation web development with the usage of UNIX router. [ 14 ] Intranet is a basal set platform, which tells us that merely a individual terminus can convey information onto the platform at merely tome which is specific. Internet hub systems take the restrictions of any entree related issues by development and implementing router for the house and all the workers are utilizing the MAC OS. Ethernet exchanging alternatively of configuring shared Ethernet attains the described functional facets: Every port on a switch is in the sphere which collides of its ain and therefore a workgroup joined to the LAN through a switch port alternatively of a hub port need non hold to fight for entree to the wire by looking for hits prior the information is sent. This maximizes the bandwidth on the LAN.Router switches in a campus anchor6.2 Data Management within the web 1. Datas Administration Data plus, Data administration, Data steward 2.

Therefore there will be informations direction along with the information direction and cognition direction. Even though informations may be present in footings of information or even knowledge they will be every clip in the head of the individual and hence they will be evaluated in the several criterions.6.3 Wireless LANsAdvantages of radio LANs include:The important demand for the radio LANs is clearly seeable because of their cost less expensive nature and simple to execution when compared to staying webs and web devices. The big figure of machines available in present market scenario is largely fitted signifier the beginning with the radio LAN nomenclature.Convenience:The Wi-Fi belongings of these sorts of webs facilitates users to acquire permissio n to use web resources form any suited topographic point inside their basic networking environment either it is a large or a little one.Mobility:With the rapid growing and use of public Wi-Fi webs, users can acquire permission to use the cyberspace even from finish external to their work atmosphere. Mast coffeehouse, for illustration, provide users a wi-fi connexion for acquiring entree to internet at minimal monetary value or even free of charge. With the lessening in the usage of laptop-level machines, this is specifically related.Productiveness:Clients joined to a Wi-Fi web can pull off a about steady relationship with their suited webs as they shift from location to location. For a chance in the concern, this tells us that a worker can significantly be efficient as his or her work can be finished from any suited topographic point. By taking into consideration of this illustration, a infirmary or depot may present voice against WLAN technologies that gives manner to mobility any best monetary values in the market.Deployment:For get downing up of an infrastructure-related Wi-Fi web it is needed to hold little sweetenings to the individual entree point. When compared with the wired webs, they have higher costs and complications of utilizing physical wires that are used for the puting up the connexion to more topographic points.Expandability:Wi-Fi webs can work even in instances with unexpected rise in the figure of users with the tools that are present merely. Whereas, a wired web more the figure of users require increased physical overseas telegrams.Cost:Wi-Fi webs require hardware which is of extremely expensive when compared to wired networks demands. This significantly raised the disbursals which are of really high when taken into consideration of the nest eggs it had made by non utilizing any wiring hardware.Disadvantages:Wi-Fi LAN engineering, by looking at the above mentioned allowances and characteristics which seem to be extremely important there are some drawbacks besides. For a given web topographic point, Wi-Fi LANs need non be the best suited 1s based on several characteristics. Several of these have work on with the built-in limitations of the engineering.Security:Wi-Fi LAN communicators are developed to ease machines on a whole unit without any dungs in the webs by the usage of wireless frequences. As a ground of infinite and disbursals, the signal receiving systems that exist on Wi-Fi networking cards in the finishs machines are largely less quality. In order to acquire proper signals by utilizing those type of receiving systems even in a best location, the Wi-Fi LAN communicator uses a maximal energy while transmittal.Scope:The normal scope of a basic 802.11g web with the common tools and engineering will lie in a scope of 10s of metres.Dependability:Similar to any other wireless frequence broadcast medium, Wi-Fi networking signals are affected to big figure of perturbations, every bit good as hard transmittal troubles like several way, or specifically in this Rican attenuation that are above the custodies of web admin. In the scenario of basic webs, transition is attained by hard stairss of phase-shift keying-PSK, amplitude modulation-QAM, doing engagement and transmittal facets all the maximized attempts.Speed:On several of the Wi-Fi webs usually 1-108Mbits/s gait is well less in contrast to the minimal degree of the basic wired webs 100Mbitsp/s to a tallness of several Gbit/s. there is besides some transmittal concerns raised by the TCP and its built-in obstructor ordinance techniques. For several users, on the other manus this illustration is non related as the velocity restriction point is non in the Wi-Fi web but taken into consideration of the external web connectivity is ensured. Taking the illustration, the highest ASDL end product usually 8Mbits/s or even lesser given by telecommunication industries to normal users is form start onwards is much lesser than the minimal velocity Wi-Fi webs to which it is fundamentally joined. Enhanced attacks such as 802.1 1n are being work outing this restriction and will backup highest end product in the scope of 100-200Mbit/s. Turning concerns that are looking frontward for rise in the web coverage of the Wi-Fi webs and less figure of limitations, needed to make up one's mind new bill of exchange 802.11n Wi-Fi tools. New bill of exchange 802.11n devices are expected to demo high degrees of efficiency and maximal connectivity country.6.4 FEATURES AND ADVANTAGES OF WIRELESS ROUTER NETWORKIn this Earth of advanced engineering, several people opt for non to fall in machines with Ethernet wiring due to maximal extent of wiring is spread around their office or abode is non a coveted one to hold. We can choose to implement a Wi-Fi web to forestall maximal wiring. For a Wi-Fi web, there is no demand to utilize Ethernet wiring to fall in our machines to the DSL or router. Basically, a Wi-Fi web transmits signal utilizes one or more Wi-Fi routers or Wi-Fi entree points. The admittance points or router are gained with an aerial and an Ethernet port. The Ethernet port in the Admission point must be joined to the modern who is provided by our cyberspace service giver, we can besides do a brotherhood of cabled and Wi-Fi connexions with an admittance point or Wi-Fi router. IEEE 802.11 constructs of Wi-Fi transmit is used in a Wi-Fi local country web ( WLAN ) . Particular other Wi-Fi networking constructs like Bluetooth are admirable at present. On the other manus, 802.11 constructs are described as the several efficient networking solutions. By and large, the aim of the interior decorators of this web entree point was to fall in machines through a local country web. On the other manus, at present it was modified and a Wi-Fi web interface is besides used for voice over cyberspace protocol ( VoIP ) and permission to utilize internet depends on the research done up to now, it is apparent that we can remain united in our web for maximal clip frame every twenty-four hours. If we have a laptop with Wi-Fi handiness, we can roll throughout the office premises without laptop while there will be no dropping in the signal or there wo n't be any connexion losingss. At present, specific urgent services are airing their private informations through a Wi-Fi web. We can make up one's mind this as an clear position for information protection which provided by Wi-Fi web. We can reassign and pass on information spontaneously by a Wi-Fi web. This is a valid facet why concern and people opt for this web base for informations sharing. Some of the valid facets which make Wi-Fi web significantly advanced are:Suitable facets like we can use this web at a abode, the office or at any topographic point and with easiness of usage.WLANs are admissible everyplace around the Earth at a minimal cost.While switching to a new topographic point, we can reassign the interface and configure it at our new topographic point with easiness.There is no demand for an Ethernet wiring to fall in machines one another.In a concern point of position, one of the important benefits in implementing a Wi-Fi web is the nest eggs, we can hold permissions for alterations in our concern in minimal clip frame after configuring the Wi-Fi web. There is no demand to sell out hard currency on wiring and other devices. The disbursals of pull offing Wi-Fi web are besides less when taken into contrast to other webs. In the present yearss, we can have Wi-Fi routers at a best coveted monetary value. Besides holding a Wi-Fi web can maximise growing and heighten the operation atmosphere in our organisation. Surely, one of the of import drawbacks of this web is that it may ensue in physical wellness conditions and atmosphere related concerns. [ 22 ]AN IDENTIFICATION OF THE SECURITY THREATSNow yearss, a mail was posted to the editor asking about the security characteristics of Wi-Fi webs and how to protect them. All Wi-Fi systems have certain sort of security issues based on how they are implemented or used. The different sorts of Wi-Fi connexion provide distinguishable methods of linking conditions on the corporate web or the cyberspace. Before stoping up the treatment and enter into the research treatment let us one time once more guarantee weather the definitions and methodological analysiss based on the subject are up to day of the month.7.1 IntroductionMany of us in the public funding occupation need to travel from office for a considerable clip frame to ease our users or travel to the events. Whole traveling from topographic point to topographic point, we trust on the user or the no cabled or wireless connexion in the accommodating topographic points to link back to the organisation to look for electronic mail updates or update the proceeding of the concern or to entree informations of the organisation or sometimes work separately by a terminal waiter.7.2 LIMITATIONSThere are several drawbacks of client-server design. Those are illustrated below:Security: In immense plan implementing security facets is a minor undertaking. But in a client-server depended design is provided with a great extent of flexibleness and a client can fall in anyplace in the web. This turns out to be a chance for interlopers to come in into the web. Hence, doing certain about the client-server engineerings is really important.Waiters can be constrictions: Waiters can move as the restricting points d ues to assorted users may fight to fall in to a waiter at the same time. This restraint occurs because of the easiness of entree provided to any client to fall in the web at any specific clip.Compatibility: Client and waiters might non to be in good footings with each other. Because of distinguishable industry may plan the client and waiter devices, they might non be suited to each other because of facets like informations types, linguistic communication and so on.Incompatibility: Cloning of waiters is a serious concern as it can originate the job of informations incompatibility.7.3 RESEARCH SCOPE7.3.1 WIRELESS OFFICE NETWORKS:Many of the funding organisations have been taught of Wi-Fi networking in their organisations but taking into consideration about the security concerns it decides. We have all known sing the WEP and intelligence in the media universe above how it had been attacked by the interlopers. In malice this is right and is a issue for Wi-Fi WEP- encoded webs, WPA-secur ed webs does non hold the similar issue, provided a rigorous security key is used. A rigorous security key could be termed as a large twine of characters taken at random from the 95 accessible keys. Taking into consideration, the lamb which Mary had spent 20 yearss in the forests is a better encoded key when compared to ABTY1386. It may necessitate several old ages to brute force Rhine wine the lamb phrase, but merely a few hours clip to chop the AB phrase. If used in good manner, WPA can supply a secure Wi-Fi web connexion for a funding organization.WEP must non be used at anytime as the encryption has been easy attacked. Using WPA is a obviously a easy technique of configuring the device for WPA connexions and so edifice that protocol on all the different Wi-Fi machines in the organisation. Provided a rigorous pre-shared key is used, the chance of the Wi-Fi web being attacked is really less. WPA can be used provided best methods are used. If WEP is being used in our Wi-Fi web, it is the state of affairs to alter to WPA.7.3.2 THE TRAVELLING WIRELESS OFFICEIn instance the client web is predicted to be to the full protected, the hotel or other Wi-Fi topographic point is estimated to be unafraid. This widens our machines and our information to be show cased to other who wanted to measure the topics of our machine. Using a package firewall does non give entree to ports which are non in usage, but there are assorted ports free to see on a machine that can give entree to person to hold a expression at informations. Some of these ports may be given entree by the package, and we may non even know that the ports are free to be entree. For illustration, in instance of horsepower pressman package this gives entree to ports on the machine that grants permission for wired web connexi ons to be granted with the machine. In laptops the cards will be installed and while fall ining the laptop in direct contact to the cyberspace through the
