SAFER Makes Safe to Walk in Space

SAFER Makes Safe to Walk in Space Its like a scene from a science fiction movie nightmare: an astronaut is working outside a spacecraft in the vacuum of space when something happens. A tether breaks or maybe a computer glitch strands the astronaut too far from the ship. However it happens, the end result is the same. The astronaut ends up floating away from the spacecraft into the endless void of space, with no hope of rescue. Thankfully, NASA developed a device for space walking that keeps an astronaut safe while working outdoors to prevent such a scenario from happening in real life.   Safety for EVAs Space walks, or extravehicular activities (EVAs), are an important part of living and working in space. Dozens were needed just for the the assembly of the International Space Station (ISS).   Early missions by both the U.S. and Soviet Union also relied on space walks, with astronauts tethered to their spacecraft by lifelines. The space station cannot maneuver to rescue a free-floating EVA crew member, so NASA got to work to design a safety harness for astronauts who would be working around it without direct connections. Its called Simplified Aid For EVA Rescue (SAFER): a life jacket for space walks. SAFER is a self-contained maneuvering unit worn by astronauts like a backpack. The system relies on small nitrogen-jet thrusters to let an astronaut move around in space. Its relatively small size and weight allow for convenient storage on the station, and let EVA crew members put it on in the station’s airlock. However, the small size was achieved by limiting the amount of propellant it carries, meaning that it can only be used for a limited time. Its intended primarily for emergency rescue, and not as an alternative to tethers, and safety grips. Astronauts control the unit with a hand controller attached to the front of their space suits, and computers assist in its operation. The system has an automatic attitude hold function, in which the onboard computer helps the wearer maintain course. SAFERs propulsion is provided by 24 fixed-position thrusters that expel nitrogen gas and have a thrust of 3.56 Newtons (0.8 pounds) each. SAFER was first tested in 1994 aboard the space shuttle Discovery, when astronaut Mark Lee became the first person in 10 years to float freely in space. EVAs and Safety Space walking has come a long way since the early days. In June 1965, astronaut Ed White became the first American to conduct a space walk. His space suit was smaller than later EVA suits, since it did not carry its own oxygen supply. Instead, a hose to an oxygen supply on the Gemini capsule connected White. Bundled with the oxygen hose were electrical and communication wires and a safety tether. However, it quickly expended its supply of gas. On Gemini 10 and 11, a hose to a nitrogen tank aboard the spacecraft connected a modified version of the handheld device. This allowed the astronauts to use it for a longer period of time. The Moon missions had EVAs starting with Apollo 11, but these were on the surface, and required the astronauts wear full space suits. Skylab astronauts made repairs to their systems, but were tethered to the station. In later years, especially during the shuttle era, the Manned Maneuvering Unit (MMU) was used as a way for an astronaut to jet around the shuttle. Bruce McCandless was the first to try one out, and the image of him floating free in space was an instant hit.   SAFER, which has been described as a simplified version of the MMU, has two advantages over the earlier system. It is a more convenient size and weight and ideal for an astronaut rescue device outside the Space Station. SAFER is a rare type of technology- the kind NASA built hoping that it wont be necessary to use it. So far, tethers, safety grips, and the robot arm have proved adequate to safely keep astronauts where they are supposed to be during space walks. But if they ever fail, SAFER will be ready.

Verbs of Being Definition (English Grammar)

Verbs of Being Definition (English Grammar) In traditional grammar and pedagogical grammar, a verb that does not show action instead indicates a state of being. In other words, a state-of-being verb identifies who or what a noun is, was, or will be. Although in English most being verbs are forms of to be (am, are, is, was, were, will be, being, been), other verbs (such as become, seem, appear) can also function as verbs of being. Compare them with stative verbs, and contrast them with verbs of doing (dynamic verbs), or action verbs. Stylistic Advice: Avoid "Be" When You Can Unfortunately, to be verbs do not make for the most exciting writing to read when a piece is overloaded with them (buzzing with bes). Action verbs are stronger than to be verbs because they portray more imagery. Action verbs also make for more impactful, shorter sentences, as to be verbs often are found in passive sentences as well. Replace being verbs where you can, during your editing round of writing your piece. (The drafting phase is for getting your information organized and put together.) Not all being verbs or even passive voice can be avoided, of course, but where they can be replaced, your sentences will be livelier  and punchier and will flow more quickly. Improving Examples Compare the following sentences and their improvements: Jerry was working hard.Jerry worked hard.Mary is a big fan of Bach.Mary adores Bach. In the latter improvement, the verb was changed completely, to be more descriptive. Excising Passive Voice To get rid of passive voice, turn the sentence around and start with the doer of the action rather than the object of the action. See the difference between: Their house was invaded by bugs.Bugs invaded their house.The package was sent by Bob.Bob sent the package. Passive voice has its place, such as when the result is more important than who did the action. For example, The record low temperature was broken last night, after 104 years, or when the actor is unknown, such as in, Its recommended to have the furnace serviced once per year. (Though these sentences still could be revised out of passive by adding subjects and recasting them, such as We hit a record low last night, breaking a 104-year record and Manufacturers recommend having...) Hamlet's "To Be or Not to Be" One of the most famous being verb sentences surely is the famous soliloquy of Hamlets, in his eponymous Shakespearean play. Author Crystal Downing reminds us, though, that people need to take into account the fact that the speech is written in iambic pentameter when working out its meaning: When people pronounce Hamlets famous line, they usually emphasize the that, as though Hamlet cannot make up his mind about killing himself: To be, or not to be-

Water pollution here in wisconsin Essay Example | Topics and Well Written Essays - 1500 words

Water pollution here in wisconsin - Essay Example It is also to be noted that higher efforts and commitments to treating waste water by the authorities and industries responsible, the ever increasing volumes of wastes from the industries and settlements overwhelm the efforts of treatment (By Amy and,Christi, para 1-6). On the other hand, weaknesses in enforcing the legal framework to curb such pollutions coupled with the compromises that result from negligence in the individual industries complicates the process and thus resulting to the ever increasing problem of contamination of water sources. In general, water protection efforts within the city suffer a myriad of issues which includes deep rooted corruption, political pressures, lack of and compromise in health standards, poor inspection and monitoring processes, ineffective riles as well as problems of increased sedimentation. The outcome of such mass pollution of the water sources within the city can be attributed to so many problems basic to which is the health complication to the residents. The discharge of contaminated water into the water sources that serve the city and the suburbs around pose a great risk to the welfare of the people within Wisconsin. Besides the aquatic life in the rivers, streams, and the lakes within the city are exposed to great risk. Fish in particular would be exposed to such risks of death from the contaminated water and this would have adverse effects not only to the populations which rely on the fish for food but also towards the economy at large (Weigel and Dale 691-708). However, the main question that remains critical is on what role the government should play in fight against water pollution within the state and the associated effects? Besides, what are exact effects of water pollution in the city with special regard to aquatic life? Finally, how does fish from contaminated water pose a health risk to the populations living

Race Relations in the USA Essay Example | Topics and Well Written Essays - 1000 words

Race Relations in the USA - Essay Example These days, most of our nation feels that racism and the connotations thereof are a thing of the past – we have Affirmative Action, which seeks to bring the nation’s ethnic minorities, especially the African Americans, out of the disadvantages a systematic discrimination has led them into, what is more today an African American is our nation’s President. Clearly, this shows that there is no systemic discrimination against the non-whites in our country, as the whites have ceded the power they once wielded. But just how true is that? Just a little inspection reveals that while it is true that there is no institutional racism in the United States, and overt racism is not tolerated at all, there are still racial undertones to almost all aspects of life. Admittedly, these racial undertones are present in relations between non-whites themselves as well, but while we cannot define the race relations completely, it is still a â€Å"white† issue. These days when mo st of the overtly racist tones of our country have been buried and when overt racist actions and speech are not only frowned upon, but also punished, there is a more pervasive form of inherent bias that exists within us. Most members of our society have implicit biases – which is to say that they have biases without consciously being aware of them. A lot of the time, people do react in a certain way when dealing with people of other ethnic communities without even realizing that they are showing a hidden bias. The Social Psychology Network has set up an Implicit Association Test online whereby they have assessed a large number of people regarding their hidden biases with regard to Whites and African Americans. The results of the tests are astounding: 73% of the total test takers show an automatic preference of varying intensity for White people, with only 16% of the test takers showing any kind of preference for the African Americans. The bias is so well hidden that we do not even know it exists, and yet the test results clearly show just how insidious and wide spread it is. Another factor that complicates race relations is the fact that we have a phenomenon called â€Å"White Privilege† that is very pervasive, but which we do not admit to. According to Robert Jensen, the United States is shaped by White Privilege; he talked to a conservative white student of his who also agreed that in a world run by white people both of them had often benefitted by the fact that they were also white (â€Å"White Privilege†). However, there is a trend to ignore the fact that the world is tilted to favor a certain race in our country, and there is still stress on there being equal opportunities for all citizens irrespective of caste or creed. According to Jensen this is the ultimate white privilege: â€Å"the privilege to acknowledge you have unearned privilege but ignore what it means† (â€Å"White Privilege†). This does not mean that white people abuse the rights of others to be where they are right now, but that there are doors that are opened to them more readily because of the color of their skin. Peggy McIntosh, in her essay â€Å"Unpacking the Invisible Knapsack† has not only talked about how there is need for us to address the white privilege, but has also identified and listed 50 things that she, as a white person, gets to experience, which other ethnic minorities do not get to experience most of the time. It is simply eye opening, to say the least, to read about all the everyday things where White people have an invisible advantage or privilege over members of other ethnic communities. For instance, according to the list, McIntosh can readily ignore â€Å"

History of Typography Essay Example for Free

History of Typography Essay First of all, what is typography? Typography is the art of letter forms being organized into certain words or sentences. Typography came from the Greek word typos which means form and graphe which means writing. Most people would agree that a German man named Johannes Guttenberg was the one who invented typography. Before Guttenberg, everything had to be scribed by hand which was very time consuming. Guttenberg also created blackletter, the first ever typeface. Since blackletter looked very compact, a man named Nicolas Jensen invented the first ever Roman typeface during the 15th century. Since Jensen’s typeface was made of straight lines and regular curves, it was easier to be read compared to the blackletter typeface. After Roman letters, the italics typeface was created during the late 15th century by Aldus Manutius. During the 18th century, a man named William Caslon created a typeface called Old Style. A few decades later, John Baskerville created a variety of typeface which is now called Transitional. A few years later, a French man named Didot and an Italian man named Bodoni created typefaces that are classified as Modern. During the second industrial revolution, advertising needed new typefaces. Letters got taller, wider, and even weirder. Since the typefaces during the 19th century were so complex, the early 20th century brought something simple. A man named Paul Renner from Germany created a typeface called Futura which was based on simple geometric shapes. In 1957, Helvetica was introduced. Some would call this the world’s most favorite typeface. The world of typography changed with the introduction of the computer – and it will continue improving since technology is constantly improving too.

Development of Business Strategies Essay -- Business Development Strat

The paper below responds to the following three prompts: 1. â€Å"The six forces model of strategy helps firms develop externally coherent business strategies†. Discuss applying the model to real cases. 2. Explain strategic posture and how it helps firms make strategy in uncertain business environments. 3. Evaluate the role of mergers and acquisitions in corporate strategy. 1. â€Å"The six forces model of strategy helps firms develop externally coherent business strategies†. Discuss applying the model to real cases. The six forces model is an extension to Michael Porter's Five Forces Model. The six forces analyze different areas in an industry. The forces in this model are: a. Competition- Analysis that if there are a lot of competitors. If so, are there any dominant players in the market. b. New entrants- To analyze if it is easy for new entrants to enter the market and compete? c. End users/buyers- Is the price easily affected by the buyers? Can the company work with a specific potential buyer? or to analyze their strength of their position in their relationship with the buyers d. Suppliers- Study the number of suppliers if it is a monopoly and if not, how many suppliers are there in the market. e. Substitutes- To study how easily a product can be substituted and how easily these substitutes are available f. Complementary products- Effect of complementary products and services on the market. The six forces model is used to study the strategic position of a company in a concerned industry and in a given market place. It is also applied to calculate the market effectiveness of a company with regard to competition and profitability. Let us take FedEx as an example.

Assess the Short Term Impact of the Economic Crisis on the League of Nations Essay

The League of Nations was created in January 10th 1920. It worked by the principle of collective security, in which all disputes threatening war would be submitted to the League and any member resorting to war would have broken the Covenant, and would face collective action by other members. However, permanent members such as Britain and France, had veto powers to reject decisions to safeguard their own national interests. Thus, unanimity was never achieved. However the league was not initially as powerful as it seemed as it lacked basic requirements such as a police force and authority overall. Therefore the great depression was not the only factor which had an impact on the league as there remained many faults in the way the league was run. The global economic crisis of 1929 affected nearly all great powers. It led to countries who owed money to each other drowning in huge debt e. g. Austria’s bank, which went bust. During the economic crisis, every country imposed high duties on imports in an effort to protect its own industries. This increased tensions between countries as they were all trying to reproduce their own economy and secure themselves as the most powerful country, but revealed the Leagues weaknesses. This is supported by a historian who states, â€Å"The situation really began to drift out of control with the onset of the great depression, it brought unemployment and living standards to most countries causing extreme right wing governments to come into power in Japan and Germany together with Mussolini, they refused to keep with the rules and took a series of actions which revealed the Leagues weakness. Japan was affected by the economic crisis of 1929, so aimed to rebuild its economy. However they did this by acquiring the south Manchurian Railway, while completely ignoring the League’s aim of avoiding aggression. China was angered by this and considered the League for help and support, so the League decided to set up an enquiry headed by Lord Lytton, who rejected Japanese claims and called for a withdrawal of Japanese forces as they refused to recognise Manchukuo as a separate state. However little did China now that the Leagues minor efforts would go to waste once Japan withdraws from the League in 1933 because without its own armed forces the League could not compel Japan to comply with the commissions demands. This shows the Leagues major weakness as it freely allowed countries to leave whenever the conditions didn’t suit them, indicating no clear system and a sense of being powerless. Robert Wolfson and John Laver share the same view as they state â€Å"this was in a sense, the moment of truth for the League – how would it deal with a member who rejected its decisions? , he later indicates â€Å"if collective security is not used effectively in Manchuria there may be a European war in 10 years’ time. † Furthermore, distracted by the great depression, the European powers and U. S lacked the will and resources to oppose Japanese militarism. The League therefore failed to live up to its ‘collective security’ and exposed how weak they were, this is backed up by Tony Howarth who states, â€Å"The invasion of Manchuria had two important side effects – putting aside for a moment its dreadful revelation that the League was powerless in the face a determined aggressor. First it raised the prestige of the Japanese army. Second, it made it possible for the army to pressurise the Japanese government to undertake a policy of armed expansion. † Here we can clearly see that the League was unable to deal with the more powerful and larger states as they were lacking power and authority, this is perfectly linked to the cartoon David Low drew in 1933 where it shows Japan getting away with trampling over the League and a League official freely allowing them to get away with the aggression (giving flowers) . This shows the League being humiliated and blames the weak leaders and not the League itself as they were not taking serious action in order to prevent Japans invasion of Manchuria, this links back to the global economic crisis as it was primarily the great depression which affected the League as the crisis was a result from the 1929 catastrophe. On October 3rd 1935 Italian troops invaded Abyssinia from Eritrea and Italian Somaliland. The League stated that Italy were the aggressors and imposed limited sanctions – they failed to place sanctions on Oil which was needed to enable the continuation of war. Sanctions were not increased or universally applied, even after it emerged that Italian forces were making use of Chemical weapons against civilians. Instead of imposing sanctions the British and French foreign ministers came up with the Hoare-Laval Pact. This pact would end the war but would grant Italy large areas of Abyssinia. This pact weakened the Leagues position as Britain and France (2 leading members) were prepared to give way to Italy. However Antony Eden reveals his contradictory views in his Telegram, â€Å"There is neither sign of any weakening in overwhelming support for the covenant which was feature of debate in Assembly nor any sign that members of the League would be unwilling to shoulder their obligations should situation demand it. The only nation which has shown a marked lack of enthusiasm for effective action under the covenant is France. Antony the British Minister favoured the League so this source can be biased as his interests would without doubt lay upon the League, however he blames France for not following the basic rules of the covenant and does not focus much on Italy’s invasion of Abyssinia, indicating that maybe he was fine with the invasion. However, A. J. P Taylor shares contrary views as he states that â€Å"There is no concrete interest in the state of Abyssinia. Mussolini was concerned to show off Italy’s strength and not require practical gain. Taylor suggests that Italy only did what they did in order to gain security for their country while having no intentions of causing conflicts and having selfish aims. Therefore did not invade Abyssinia for economic reasons. What is more, is that the global economic crisis brought right wing leaders into power e. g. Adolf Hitler, who was looked upon as a great leader and last resort in Germany who could introduce reforms and change Germany’s economy for the better, especially after they were blamed for the outbreak of the war and faced major reparations which worsened their economy, far more than any other major countries economy. The great depression gave Hitler the opportunity to aggressively campaign in order to secure Lebensraum and recover territories lost, this frustrated Leagues efforts to maintain peace as they were not living up to their policy of ‘collective security’. Germany left the League of Nations in 1933, which made it even harder for the other great powers to control and regulate actions taken by Hitler. An example of Hitler’s daring improvisations was the re-occupation of the Rhineland in March 1936, which could no longer be dealt with by the League of Nations as it lost the control to interfere with what Germany did. Therefore in general the great depression had a major impact on the League of Nations as it exposed every bit of the Leagues weakness, as supported by Robert Wolfson and John Laver who states â€Å"each of these coincidences and accidents made it all the easier for a collective security system to fail. † However it is fair to say that the League itself was not initially powerful. It lacked authority and had no police force whatsoever, hence the reason why powers were continuously threatening to leave the League, such as Japan and Germany’s withdrawal in 1933. This undermined the Leagues power as it simply failed to control the League’s members and what was worse it that any country could join the League when it suited them, which caused divisions and conflicts as the policy of ‘collective security’ was not turning out to be very successful as it primarily was thought to be. During Neville Chamberlain’s speech, he stated â€Å"the league of nations and the policy of collective security to which we have given so whole – hearted support with such disappointing results†¦. We should therefore abandon the idea of the League and give up the ideals for which the League stands† He is clearly undermining the Leagues power and indicating that they did not live up to what they promised. Chamberlain shares the views that the League might have been able to sort out little problems but it was clearly unable to stop major crisis as the Nations would have to find another way to deal with that. Hitler’s Mein Kampf reveals how he felt about the League of Nations, â€Å"they did not realise that in most cases they were dealing with persons who had no backing whatsoever, who were not authorized by anybody to conclude any sort of agreement whatsoever; so that the practical result of every negotiation with such individuals was negative and the time spent in such dealings had to be reckoned as utterly lost. † Here Hitler is expressing how the League were clearly not organised and had no authoritative figure or system whatsoever which is a major setback and a failure of how the League was run overall. Another major issue was the fact that the U. S. A and USSR did not join the League. This was a problem as these were the only 2 powers near enough and strong enough to take effective action, however were not members of the League, which is why the League lacked power and authority. â€Å"America’s consistent refusal to use nothing more than words in support of the League had shown just how toothless and helpless the international community was when it came to enforcing and upholding the peace. A dangerous precedent had been set. † This can be linked to the cartoon called ‘the gap in the bridge’, which shows a gap in the bridge and a keystone which represents USA, not joint to the bridge, preventing the League from being stable and unable to function without USA’s support, so consequently all the foreign nations try to pull USA into the League as they are desperate for a Nation which is military and economically stable, hence tied and dependent on the US. In conclusion the global economic crisis had a huge impact on the League as it exposed its weaknesses and undermined its authority and power. †the existence of the League caused cabinets and foreign ministers to wobble between the old and the new diplomacy, usually securing the benefits of neither, as the Manchurian and Abyssinian cases amply demonstrated. † However the setup and running of the League itself lacked enforcement powers and had no real machinery of collective security. Ironically, therefore the Leagues actual contribution turned out to be not deterring aggressors, but confusing the democracies. † Hence after analysing many contemporary sources and historian views it was mainly the global economic crisis which had an impact on the League of Nations as it highlighted and exposed the weaknesses of the League while undermined its system of ‘collective authority’.

Analysis of Scene 5 Act 1 of Macbeth Essay

Macbeth Scene AnalysisAct 5 Scene 11)Plot SummaryIn this scene the gentlewoman who accompanies Lady Macbeth while she sleeps has previously reported to a doctor of her sightings of Lady Macbeths deranged sleepwalking not long after Macbeth left to prepare for battle. Here both of them keep watch to see if any of Lady Macbeths sleepwalking occurs again. It starts off with the doctor and gentlewoman discussing Lady Macbeths condition. During Lady Macbeths sleepwalk she had previously, she confessed to the murder of Duncan that she and her husband committed. However when the doctor asks the Gentlewoman whether In this slumber agitation, besides her walking and other actual performances what at any time have you heard her say? but the gentlewoman refuses to answer as she doesnt want to get involved. Later in the scene Lady Macbeth starts sleepwalking carrying a candle which the gentlewoman states that Lady Macbeth always insists on having it near her bed. 2)Character Analysis Major Characters. In Act V. Scene i. the major character that we see is Lady Macbeth. I think the main message we perceive from this scene about Lady Macbeth is that her bravery was all a pretense and on the outside, but really her conscious was afraid and in shock about what she had driven her husband to do. The metaphor used to describe the lingering shadow of the dirty deed is the spot. When Lady Macbeth starts talking she keeps on repeating the same thing over and over again begging for the damned spot to get off her hands. The spot was the left over blood marks and smell of the murder that all the perfumes of Arabia will not sweeten this little hand. Shakespeare uses indirect characterization to show us that Lady Macbeth has a guilt side of her that she tried so hard to mask. Although we have always known Lady Macbeth as the strong, ruthless ambitious one of the two however in this scene she falls apart and becomes vulnerable to the guilt that built up inside her. This shows that although the rest of the people of Scotland think of Lady Macbeth and her husband as strong powerful people, this scene lets us know that there is more behind their dynamic characters. 3)Character Analysis Minor CharactersIn this scene there are two minor  characters, the Doctor and the Gentlewoman. Although they are minor characters they play especially significant roles in this scene as they are the ones to witness the confession of the murder of King Duncan that she and Macbeth committed. Things that we learn about the doctor in this scene include that he is a man with patience as at the beginning of the scene he says I have two nights watched with you but can perceive no truth in your report. When was it she last walked? This showed that he either had the patience to wait and see the condition of Lady Macbeth or he didnt want to disobey command of the rulers. He couldve just said on the first day/night that he didnt see any evidence of Lady Macbeths sleepwalking and left to do his job in other places. The doctor is a flat character as he doesnt appear several times throughout the story yet he is still quite important. He is also an inquisitive person as he honestly reports to the gentlewoman of his observations and he asks several questions where it is required. He is straightforward as he doesnt waste time trying to pretend that he knows how to cure Lady Macbeths sleepwalking as he says This disease is beyond my practice;The gentlewoman is also a flat character as she only served as the link to the doctor finding out about Lady Macbeths sleepwalking. In addition, she doesnt reappear in the rest of the story. However she still played an important part as she was the one to first encounter the sleepwalking Lady Macbeth. The gentlewoman is a straight forward person as she directly answered most of the questions she was given. The only thing she didnt answer was about whether Lady Macbeth spoke while she sleepwalked. The gentlewoman seemed loyal as she did not want to get involved with the situation of Duncans murder so she said to the doctor she wont repeat what Lady Macbeth said. 4)Language FeaturesShakespeare uses a lot of language features in this scene. This scene shows a lot of irony compared to Act 2 Scene 2. In that scene she says Retire we to our chamber; a little water clears us of this deed. Which was basically she telling Macbeth not to worry but their actions will not be found out of. Yet here she is the spirits of the deed haunting her still, after several weeks. Contradiction is also used for the same reason and way irony is used. Lady Macbeth contradicted herself from Act 2 Scene 2, by saying nothing will go wrong when we can clearly see that in this scene  nothing is close to right. 5)ThemesThe theme that Shakespeare explores greatly throughout the whole of Macbeth, is moral thoughts. In this scene he indirectly tells us that there is never an easy way out of a bad deed, for whether you are caught or not your guilt will haunt you forever. However in this scene Macbeth uses the theme of Masks. The theme of masks is basically how throughout the whole play we see different sides of the major characters Macbeth and Lady Macbeth, they put on different masks depending on who they are with. 6)ConnectionsFor this play I found out a very interesting relationship between it and the movie Final Destination. In this movie the story starts off with one of the characters, Alex, having a premonition of him and his friends crashing in a plane ride to Paris, which can be compared to the three witches having a vision of Macbeth as king and giving the information to Macbeth. Then on the plane Alex realizes that everything is going the way things were in his dream, and he runs off the plane in fear, bringing 6 other friends with him. As the story develops, the characters realize they cannot cheat death as one by one they start to die according to how they wouldve died in the plane. They spend the movie trying to find a way to not die, but in the end the only one that survives has locked herself in an asylum room where she goes crazy, just like Lady Macbeth went crazy in Act 5 Scene 1. In Macbeth even though they cheated their way to the throne by killing Duncan, Banquo and the other people meant to get the title of King, Macbeth and Lady Macbeth both die at the end as their plans fail and they end up as miserable people.

When to Use GET and POST in Ajax

When to Use GET and POST in Ajax When you use Ajax (Asynchronous JavaScript and XML) to access the server without reloading the web page, you have two choices on how to pass the information for the request to the server: GET or POST. These are the same two options that you have when passing requests to the server to load a new page, but with two differences. The first is that you are only requesting a small piece of information instead of an entire web page. The second and most noticeable difference is that since the Ajax request doesnt appear in the address bar, your visitors wont notice a difference when the request is made. Calls made using GET will not expose the fields and their values anywhere that using POST does not also expose when the call is made from Ajax. What You Should Not Do So, how should we make the choice as to which of these two alternatives should be used? A mistake that some beginners might make is to use GET for most of their calls simply because it is the easier of the two to code. The most noticeable difference between GET and POST calls in Ajax is that GET calls still have the same limit on the amount of data that can be passed as when requesting a new page load. The only difference is that because youre only processing a small amount of data with an Ajax request (or at least thats how you should use it), you are far less likely to run into this length limit from within Ajax like you would with loading a complete web page. A beginner may reserve using POST requests for the few instances where they do need to pass more information that the GET method allows. The best solution when you have lots of data to pass like that is to make multiple Ajax calls passing a few pieces of information at a time. If you are going to pass huge amounts of data all in the one Ajax call, you would probably be better off simply reloading the entire page since there will be no significant difference in the processing time when huge amounts of data are involved. So, if the amount of data to be passed isnt a good reason for choosing between GET and POST, then what should we use to decide? These two methods were in fact set up for entirely different purposes, and the differences between how they work are in part due to the difference in what they are intended to be used for. This not only applies to using GET and POST from Ajax but really anywhere these methods might be employed. The Purpose of GET and POST GET is used as the name implies: to get information. its intended to be used when you are reading information. Browsers will cache the result from a GET request and if the same GET request is made again, they will display the cached result rather than re-running the entire request. This is not a flaw in the browser processing; its deliberately designed to work that way so as to make GET calls more efficient. A GET call is just retrieving the information; its not meant to change any information on the server, which is why requesting the data again should return the same results. The POST method is for posting or updating information on the server. This type of call is expected to change the data, which is why the results returned from two identical POST calls may very well be completely different from one another. The initial values before the second POST call will be different from the values before the first because the initial call will have updated at least some of those values. A POST call will therefore always obtain the response from the server rather than keep a cached copy of the prior response. How to Choose GET or POST Instead of choosing between GET and POST based on the amount of data you are passing in your Ajax call, you should choose based on what the Ajax call is actually doing. If the call is to retrieve data from the server, then use GET. If the value to be retrieved is expected to vary over time as a result of other processes updating it, add a current time parameter to what you are passing in your GET call so that the later calls will not use an earlier cached copy of the result that is no longer correct. Use POST if your call is going to write any data at all to the server. In fact, you should not only use this criterion for selecting between GET and POST for your Ajax calls but also for when selecting which should be used for processing forms on your web page.

Seleucus as a Successor of Alexander

Seleucus as a Successor of Alexander Seleucus was one of the Diadochi or successors of Alexander. His name was given to the empire he and his successors ruled. These, the Seleucids, may be familiar because they came into contact with the Hellenistic Jews involved in the revolt of the Maccabees (at the heart of the holiday of Hanukkah). Seleucuss Early Life and Family Seleucus himself was one of the Macedonians who fought with Alexander the Great as he conquered Persia and the western part of the Indian subcontinent, from 334 on. His father, Antiochus, had fought with Alexanders father, Philip, and so it is thought Alexander and Seleucus were around the same age, with Seleucus birthdate about 358. His mother was Laodice. Starting his military career while still a young man, Seleucus had become a senior officer by 326, in command of the royal Hypaspistai and on Alexanders staff. He crossed the Hydaspes River, in the Indian subcontinent, along with Alexander, Perdiccas, Lysimachus, and Ptolemy, some of his fellow notables in the empire carved by Alexander. Then, in 324, Seleucus was among those Alexander required to marry Iranian princesses. Seleucus married Apama, daughter of Spitamenes. Appian says Seleucus founded three cities that he named in her honor. She would become the mother of his successor, Antiochus I Soter. This makes the Seleucids par t Macedonian and part Iranian, and so, Persian. Seleucus Flees to Babylonia Perdiccas appointed Seleucus commander of the shield bearers in about 323, but Seleucus was one of those who murdered Perdiccas. Later, Seleucus resigned command, surrendering it to Cassander, son of Antipater so that he could govern as satrap the province of Babylonia when the territorial division was made at Triparadisus in about 320. In c. 315, Seleucus fled from Babylonia and Antigonus Monophthalmus to Egypt and Ptolemy Soter. One day Seleucus insulted an officer without consulting Antigonus, who was present, and Antigonus out of spite asked for accounts of his money and his possessions; Seleucus, being no match for Antigonus, withdrew to Ptolemy in Egypt. Immediately after his flight, Antigonus deposed Blitor, the governor of Mesopotamia, for letting Seleucus escape, and took over personal control of Babylonia, Mesopotamia and all the peoples from the Medes to the Hellespont....- Arrian Seleucus Takes Back Babylonia In 312, at the Battle of Gaza, in the third Diadoch War, Ptolemy and Seleucus defeated Demetrius Polorcetes, son of Antigonus. The next year Seleucus took Babylonia back. When the Babylonian War broke out, Seleucus defeated Nicanor. In 310 he defeated Demetrius. Then Antigonus invaded Babylonia. In 309 Seleucus defeated Antigonus. This marks the start of the Seleucid empire. Then in the Battle of Ipsus, during the fourth Diadoch war, Antigonus was defeated, Seleucus conquered Syria. After Antigonus had fallen in battle [1], the kings who had joined with Seleucus in destroying Antigonus, shared out his territory. Seleucus obtained then Syria from the Euphrates to the sea and inland Phrygia [2]. Always lying in wait for the neighboring peoples, with the power to coerce and the persuasion of diplomacy, he became ruler of Mesopotamia, Armenia, Seleucid Cappadocia (as it is called) [3], the Persians, Parthians, Bactrians, Arians and Tapurians, Sogdia, Arachosia, Hyrcania, and all other neighboring peoples whom Alexander had conquered in war as far as the Indus. The boundaries of his rule in Asia extended further than those of any ruler apart from Alexander; the whole land from Phrygia eastwards to the river Indus was subject to Seleucus. He crossed the Indus and made war on Sandracottus [4], king of the Indians about that river, and eventually arranged friendship and a marriage alliance with him. Some of these achievements belong to the period before the end of Antig onus, others to after his death. [...]- Appian Ptolemy Assassinates Seleucus In September 281, Ptolemy Keraunos assassinated Seleucus, who was buried in a city he had founded and named for himself. Seleucus had 72 satraps under him [7], so vast was the territory he ruled. Most of it he handed over to his son [8], and ruled himself only the land from the sea to the Euphrates. His last war he fought against Lysimachus for the control of Hellespontine Phrygia; he defeated Lysimachus who fell in the battle, and crossed himself the Hellespont [9]. As he was marching up to Lysimachea [10] he was murdered by Ptolemy nicknamed Keraunos who was accompanying him [11].This Keraunos was the son of Ptolemy Soter and Eurydice the daughter of Antipater; he had fled from Egypt through fear, as Ptolemy had in mind to hand over his realm to his youngest son. Seleucus welcomed him as the unfortunate son of his friend, and supported and took everywhere his own future assassin. And so Seleucus met his fate at the age of 73, having been king for 42 years.- Ibid Sources Diodorus xviii Justin xiiiPlutarchNeposJona LenderingCurtius x.5.7 fGreek Coins and Their Parent Cities, by John Ward, Sir George Francis HillMasters of Command by Barry StraussGhost on the Throne, by James RommAlexander the Great and His Empire, by Pierre Briant

Public relations thrives on public opinion Research Paper

Public relations thrives on public opinion - Research Paper Example Soon after, a large number of companies and organizations started employing publicity tactics to attract large audiences. The Excellence Project Vercic, L.A. Grunig (1996) states that nine generic principles govern the basis of setting up global public relations. Edward Louise Barneys is considered an America pioneer in the development of techniques relating to public relations and propaganda. Edward Barneys is considered as the ‘father of public relations’. Edward Barneys developed many influential PR techniques including press release and third party advocacy. Barneys helped remove the taboos surrounding the idea of women smoking in public, thorough his famous campaign of 1920 known as the Women’s Smoking Campaign. Barneys educated the industries regarding the importance of news and stated that it was the most effective method of conveying message to the public. Edward Barneys summarized the importance of PR techniques in his famous quotation given below: This quotation fully explains the importance of public relations and public opinions in setting up a democratic system. In modern world, setting up a democratic system encompasses various aspects. One of the major aspects in establishing democracy is public relations. The research following the development of Excellence theory shows that public relations serve as a pivotal condition for the establishment of a liberal democracy. During the 20th century, public relations gained the status of becoming a powerful and influential industry, not only in the United States of America but across the whole world. In modern society, public relation operations are not just limited to the in-house activity of public corporations and public institutions, but are also being increasingly established as independent consultation firms. Thus, public relation operations have become a prominent constituent in
