Understanding Delphi SET Type - Expert Guide

Understanding Delphi SET Type - Expert Guide One of the Delphi language features not found in other modern languages is the notion of sets. Delphis set type is a collection of values of the same ordinal type. A set is defined using the set of keyword: Set types are usually defined with subranges. In the above example, the TMagicNumber is a custom subrange type allowing variables of the TMagicNumber type to receive values from 1 to 34. Simply put, a subrange type represents a subset of the values in another ordinal type. Possible values of the set type are all the subsets of the base type, including the empty set. A limitation on sets is that they can hold up to 255 elements. In the above example, the TMagicSet set type is a set of TMagicNumber elements - integer numbers from 1 to 34. The declaration TMagicSet set of TMagicNumber is equal to the following declaration: TMagicSet set of 1..34. Set Type Variables In the above example, the variables emptyMagicSet, oneMagicSet and anotherMagicSet are sets of TMagicNumber. To assign a value to a set type variable, use the square brackets and list all the elements of the set. As in: Note 1: every set type variable can hold the empty set, denoted by []. Note 2: the order of the elements in a set has no meaning, nor is it meaningful for an element (value) to be included twice in a set. The IN Keyword To test if an element is included in the set (variable) use the IN keyword: Set Operators The same way you can sum two numbers, you can have a set that is the sum of two sets. With sets your event has more operators: returns the union of two sets.- returns the difference of two sets.* returns the intersection of two sets. return true if two sets are equal - have the same element. returns true if the first set is a subset of the second set. returns true if the first set is a superset of the second set. returns true if two sets are non-identical.IN returns true if an element is included in the set. Heres an example: Will the ShowMessage procedure be executed? If so, what will be displayed? Heres the implementation of the DisplayElements function: Hint: yes. Displayed: 18 | 24 |. Integers, Characters, Booleans Of course, when creating set types you are not restricted to integer values. Delphi ordinal types include character and boolean values. To prevent users to type alpha keys, add this line in the OnKeyPress of an edit control: Sets with Enumerations A commonly used scenario in Delphi code is to mix both enumerated types and set types. Heres an example: Question: will the message be displayed? Answer: no :( Sets in Delphi Control Properties When you need to apply bold to the font used in TEdit controls, you either use the Object Inspector or the following code: The Fonts Style property is a set type property! Heres how it is defined: So, an enumerated type TFontStyle is used as the base type for the set type TFontStyles. The Style property of the TFont class is of type TFontStyles - therefore a set type property. Another example includes the result of the MessageDlg function. A MessageDlg function is used to bring up a message box and obtain the users response. One of the parameters of the function is the Buttons parameter of type TMsgDlgButtons. TMsgDlgButtons is defined as a set of (mbYes, mbNo, mbOK, mbCancel, mbAbort, mbRetry, mbIgnore, mbAll, mbNoToAll, mbYesToAll, mbHelp). If you display a message to the user containing Yes, OK and Cancel buttons and you want to execute some code if either the Yes or Ok buttons were clicked you can use the next code: Final word: sets are great. Sets might appear confusing to a Delphi beginner, but as soon as you start using set type variables you will find out they provide much more then it sounded in the beginning.

Why was Mussolini able to come in to power as early as 1922 Essays

Why was Mussolini able to come in to power as early as 1922 Essays Why was Mussolini able to come in to power as early as 1922 Essay Why was Mussolini able to come in to power as early as 1922 Essay Mussolini took a considerable short amount of time to come to power a substantial three years. Mussolini came to power within a couple of years and the main point to argue this is due to the fact of the weakness of Italy as a whole. Italy was a breading ground for the Fascist regime and Mussolini took full advantage of this and he profited from this a large amount. Italy had a lot of problems before the First World War and they only got worse after the war. Italy fought the war mostly against the Austrians along there northern boarders and was conflicted with severe causalities. The problems that Italy faced after the war included discontent amongst the citizens of Italy, economical problem and also cracks amongst the Italian government. Italy dealt with heavy casualties and their national debt rouse from 16 billion lire in 1914 to an enormous 85 billion lire in 1919. Other areas that hit Italy were their industries; the ammunition industry suffered heavily after the First World War as the demand for weapons dramatically decreased. This was a very good happening for Mussolini because at this time the people needed somebody to look up to, to guide them through this hardship and lead them to good times. Mussolini rose from power at the exact right time and he benefited from this. The government of Italy proved to be a key factor in the rise of power for Mussolini. The Italian government was very weak at the time and became even weaker when proportional representation was introduced. The first issue that the government faced was the actual parties in the government. The government was divided between the two major groups which rarely agreed on anything so making decisions were very hard to be made. The socialist party would never agree with anything the popular party agreed on so coalitions were rarely made. Other parties such as the General Confederation of Labor, Italian Confederation of Workers and the Communist party were not able to gain too much power because the appealed only to certain group of people. Unlike Fascism, which was formed for a certain group of people. The government basically was very weak and Mussolini did not have to do much in making the people believe that the Fascists party would make the government stronger as the Italian government was too weak to understand the meaning of strong. The popularity of Socialist was another factor that worried a lot of people in Italy; people were scared that the Socialist would cause a revolution like the Bolsheviks in Russia and cause chaos in Italy. People were afraid of the socialist parties as there occasionally strikes and ransacking made them feel that the government could not control them. But overall the Socialist party was a very weak party indeed, historian Mack Smith argues that Socialism lacked responsible leadership and had no clear aim of how to reach power and the fact that they never co-operated with other parties. If they had done so they would have achieved control of Italy easily but they did not and were taken apart. Mussolini again took advantage of this problem and announced to the people that he could resolve the socialist problems and his political army of Fascists would crush there strikes and ransacking. He was seen as a savior for the people of Italy and he gained popularity with the public after his outbursts of future intentions and Italys bright future. Even though that the ras were crucial for the success of fascism, Mussolini had a lot of characteristics which made him and made people see him as a good leader. Mussolini had many abilities such as in writing and as a leader he knew what the people demanded from him. He was a natural speaker, his ability to speak publicly was immaculate as he would grip his crowd and leave them roaring with excitement. Also he was the only person that was in control of the ras, who in turn was seen by the ras as vital because the movement needed a very strong a reliable figure that the people could support. His flexible policies also enabled more people to appeal to Fascism thus gaining a lot of support in a short amount of time. Another key factor that led to the Fascists coming to power would be the March on Rome. This was when Mussolini was invited to become the Prime Minister of Italy by the King, as he did not want his cousin to gain power over Italy. As a result he gained a lot of support from the people and it was his first real large step that gave him power before 1922. The fascists were able to gain power in such a short time mainly because Italy was overall an extremely weak country. In only three years fascism came into power with only several seats in parliament, it could have been stopped but a few lucky events proved lucky for Mussolini and handed him power in 1922. He was very lucky at times an example being the March on Rome, Mussolini himself did not expect himself to gain power so easily so worried and was prepared to flee, but still he conquered Rome and was given power easily. If the socialist party had been more organized and co-operative then they might have come to power, but fate played into Mussolinis hands. Although the movement could have been stopped very easily, the weakness of the government to take action against the Fascists gave then success and this was why Mussolini and the Fascist party was able to achieve dominance of Italy.

Major causes of the 2008 stock market crash Essay

Major causes of the 2008 stock market crash - Essay Example Even though in numbers this was not as bad as the 22.6 percent loss that had been experienced on Black Monday in 1987, the opinion of the analysts was that this was worse since the losses were felt for the whole week and they did not come from a one-off down day. This was not the end of the experiencing of losses as in the week that started on 6 October; the Dow Jones had no other choice but to close down 5/5 trading sessions and in the process losing a further 18 percent in the same week. Later on, on 24 October the stock exchange indexes all over the globe experienced a drop of ten percent in one day. The prices of oil affected commercial activities in the United States by making things expensive and a lot of this was as a result of the speculation by the analysts in the future markets, but the demands that were legitimate resulted in the boom times and consequently the prices of oil progressively increased. The countries that have emerging markets such as China, Brazil, India as well as Russia created very huge demands for many commodities. The key factor that led to the stock markets crashing in 2008 was the subprime mortgage crisis that was being experienced in the United States since the companies were lending to people with who had bad credit ratings that would result in the people not being able to pay the loans adequately (Farmer 154). The banks in the United States were exposed to these loans, which led to their subsequent collapse since they were lending the money that they themselves had in their own banks. This greatly affected the debt to equity ratio of these banks and many of them ended up needing the help of the government to remain afloat. When many of the shareholders realized that their banks were at risk, they did not want their money invested in the shares of those banks and decided to sell the shares that they had causing a snowball effect at the stock market and this was the

The grand theatre leeds Essay Example for Free

The grand theatre leeds Essay Linda as a child is very excitable and active. She is dressed up (by her mother) in a very feminine way, however, she was a real tom boy inside. She carried on in everyday life things such as sitting down, as if she was a boy, legs wide open and crossed, as if unaware of the fact she was revealing her knickers to boys. On this scene when Linda is sticking up for him, they treat each other as the same sex, they are all the same as far as they are concerned, and they are totally oblivious to the world around them. Another scene when they are together is the scene when Mickey introduces Edie to Linda. They are all sat playing shooting with the guns. They are all extremely imaginative as they believe there are really shooting things. The three children are sat in the corner of downstage right, they are situate here so it makes them look smaller than they actually are because there is all the space around them compared to the amount of space used when the adults are on the stage. Here the relationship between Linda and Mickey is at its strongest. Linda hits the target every time, whereas Mickey misses, he doesnt show that he is jealous though. She laughs like a boy here, she feels completely at ease with him. Linda-Nikki Davis Jones-portrays the age of Linda very well here by shoeing the amount of concentration on her face when she is shooting, she is totally engrossed in her target. The relationship between Mickey and Linda is very close at this age and Mickey is not afraid to show his affections towards Linda or his mum. He doesnt think about his affections though, they are what come naturally to him; he loves to get excited and jump around. E. g. when Mickey bends over Linda to get the gun off Eddie he leans on her, whereas soon when he is a teenager he would never get as close to her as that without feeling embarrassed. The way Linda laughs when she wins shows the lack of problems and stress they had in between the relationship at that age, she is laughing with happiness and such an open body line, she has nothing on her mind. She has a lot of respect for Mickey but different to the respect he has for his brother, in the way that Linda laughs , flinging her head back as she does, she sees her self as equal to him, and would not get embarrasses in front of him. As teenagers Linda and Mickey are totally different. In the scene on the stile Linda is much more psychological, she thinks about her movements and what reactions they might have on Mickey. She is very flirtatious whereas Mickey is the shyest we have seen him in the whole play. Linda is stood astride on the stile; she is wearing her extremely short school skirt with her shirt buttons undone at the top. This outfit alone makes her look a lot older than she is (14) not because the actress is older but because her body language too is very different to hers as a child. When she talks to Mickey she tends to move forward from the waist as she speaks, revealing the space between her bra and her shirt. She intends to flaunt this to Mickey and his reactions are the total opposite of Lindas body language. He looks away and has his body on an angle to hers. He is embarrassed at the position she puts him in. Linda lets her hair down; she thinks that this will make her appear sexier. She is very impulsive here and doesnt seem to get embarrassed at all. She is much more sexually aware than Mickey and she thinks hes playing hard to get but really, he just thinks shes weird. Mickeys eye contact is very flickery and he doesnt actually look her in the eye very often. Her eye contact is very intimidating, her whole body level is a lot higher than him (because she is stood on the stile) and therefore she is looking down on him, making him feel small, her eye contact is fixed though in his eyes. She speaks in a slow provocative voice. When she deliberately gets stuck on the stile Mickey feels unsure what to do about this. She asks him for his help, she even says this sexily her knowing that he will feel uncomfortable about being so close to a girl wearing such a short skirt. He walks over and helps her and she presses her body close to him. Her eyes are still intensely looking upon him, he is aware that she is trying to flirt with hi but he is unsure how to react to it. He doesnt smile at all through this scene he tends to keep a straight face throughout but, making it obvious that something else is going on in his troubled mind. Linda and Mickey are almost at the end of the play, during the scene where Linda is trying to stop Mickey from taking his pills: In this scene both actors portray their complete change in characters well. Mickey has lost all pride in him self, he can barely look at Linda. They argue, this is a complete shock to the audience because you have seen them grown up from the age of 7 and yet you have never seen them argue. They have always stuck by each other. Linda is still behind Mickey but he is not the same anymore. Since Mickey got out of prison he had to take anti-depressants. Mickey has lost a lot of things, as a child he lost his dad. That is not something which has been an issue in the rest of the play. AS a child he lost his twin, he does not know about this but it makes the audience feel for him as all his life he has lost thinks. He lost his job, this made him become very cynical about life and be annoyed with Eddie his blood brother, this was the start where everything went wring. He had been made to grow up too fast, he had needed to, and he was annoyed with envy that Eddie was having such a good life. This showed tragic irony because; if his mother had have given him away he would have been in Eddies position not leading the terrible life he was now. His brother Sammy was his idol; right from the very beginning he looked up to him and loved him. He thought that Sammy was perfect from the beginning, but gradually, especially in the teenage section, he realised that Sammy was street- cred but was not who he wanted to be. Recently Mickey had been put under emotional blackmail from his brother; he didnt want to grass his brother in to the police because his brother got himself into trouble trying to help him. He had that dilemma on his mind. The weights of these problems and losses on his mind were conveyed amazingly in the pills scene. Mickey was pale; he looked several years older than he actually was. He was stooped over at the shoulders and wore brown baggy jumpers, trying to hide him. He lacked confidence because of his poor stance. Before he would stand tall and from the age of 17+ he was very open to Linda in a sexual way. Now they were so different he barely looked at her because he knew that he had given up on his life and felt ashamed that he had. When Linda was shouting at Mickey the tension felt was so intense because their body language was so private to themselves. This scene was the most emotional moment in the play for me because everything had gone wrong. You could see the frustration in Lindas face, she was frowning as she was shouting, she loved him and she had to watch her husband making a mess of his life because of the drugs. The voice skills the actor used here were brilliant; he talked in a monotone voice rather than Mickeys usual exciting voice. He also twitched which Mickey never did before; this showed what the drugs had done to him. All of the facial expressions and vocal skills were very subtle yet effective. The relationships between Linda and Mickey changed throughout the play; at the beginning they were extremely relaxed, fun, carefree, and full of life. AS teenagers they came to have more issues on their mind e. g. school life, one another, but they still kept the fun, and liveliness theyd had as a child. As young adults they had been forced to grow up as quickly as they did because they had to get married because Linda was pregnant. Because they had been forced to grow up like they did, they were face with more problems. Mickeys facial expressions throughout the play were the key to the audience believing whatever age he was, as a child they were much more impulsive and cheeky, as an a teenager he often looked embarrassed, and as an adult he looked extremely miserable, and stress ridden. Mickey and Linda both played their ages perfectly throughout the play and this were showed through their detailed voice skills, movement, facial expressions, and characteristics which ran through each scene. Willy Russell wrote this musical in a very witty and intelligent way. I noticed that in the beginning of the play there was a lot of humour, especially in the scenes between Linda Eddie and Mickey. The humour was used in ways which would show Eddies up bringing to be very different to Linda and Mickeys.

Saloon Culture Essay -- essays research papers

Saloon Culture   Ã‚  Ã‚  Ã‚  Ã‚  Royal Melendy writes about a rising social culture taking place at the turn of the twentieth century. He depicts this culture as the ambiance emitted in early Chicago saloons. â€Å"Saloons served many roles for the working-class during this period of American history, and were labeled as the poor man’s social clubs† (summary of saloon culture, pg. 76).   Ã‚  Ã‚  Ã‚  Ã‚  Saloons were described as part of the neighborhood. An institution recognized and familiar to its people. Many laws restricted their services; however, they continued to exist. The article talks about two types of saloons. The first being the more upscale in downtown districts. These would close around midnight not in accordance to law, but demand. The other type Melendy calls â€Å"saloons [of] workingmen’s districts† (Melendy, pg. 77). He illustrates these clubs as home away from home. They supplied the basis of food supply for those whose home was in the street or for those residents of cheap lodging establishments. It is even stated that many saloons provided free lunches.   Ã‚  Ã‚  Ã‚  Ã‚  The article discusses the need for these early Chicago saloons as a neighborhood commune for those men who labor long hours only to come home to poverty and despair of a desolate household. Melendy focuses on the mental, physiological, and moral nature of these workingmen. He points out that this saloon culture allows it’s patrons to develop these traits by interacting with their peers—others facing the same despair. These establishments are described as the â€Å"workingman’s school. He is both scholar and teacher† (Melendy pg. 78). Patrons gather at the bar, around tables and in the next room amongst games of pool, cards, and darts to discuss political and social problems, sporting news, and other neighborhood gossip. Here men, native and immigrant, exchange opinions and views of patriotism, brotherhood, and lessons in civil government. Melendy describes this atmosphere as cosmopolitan, and articulates that these businesses advertise this issue in their names. For example one of the downtown saloons was entitled â€Å"Everybody’s Exchange.† The saloon’s customers experienced a buffet of nationalities upon which was not so for those of poverty in previous decades. Saloons also served as disguises of corruption as Melendy illustrates by declaring â€Å"... ... Melendy’s discussion are lightly touched on in the excerpt. The article does explain how some patrons abused alcohol and would â€Å"revel in drunkenness and shame,† (Melendy, pg. 76) and even how the saloon wrecked their life. It also expresses the fact that some saloons would display nudeness and play on human lust in order to boost liquor sales.

Conservation and Preservation Essay

The main distinction among the two points is conservation is utilizing an area’s supplies drawn upon at a sustainable proportion in array to gain from its resources and to additionally decrease environmental harms or changes. Preservation maintains natural uninhabited or inhabited only by wild animals, and relations and interactions between organisms and their environment without embarrassing it with anything unnatural. They are nature friendly all the same one allows us to work with natural resources by keeping up sustainability for coming generations although the other retains nature and its resources in their current condition. In a subject of belief, one is more excellent than the other for all that it may not capable of being done. I think we should be knowledgeable of our habitat and less dependent on resources from other countries. This appoints preservation least probable and conservation more beneficial. Provided that we could attain a different aspect to acquire the essentialities we need to carry on without bothering the natural state of the terrain, we will be capable to maintain and preserve. In the Bridger Teton (VLR) the folks think that the region is more priceless than the resources it may supply. They look at the land as incapable of being replaced in its natural condition even provided that nature friendly procedures were applied to acquire the resources it can contribute. We have developed into a civilization which has taken away beyond what we need. Being torn between the two sides I do not think that we must be taking any extra resources for our individual private boost, and I conclude that we should not be gathering more resources from the woodland area. All of it needs to be left alone. We should stick to working with the resources we have previously seized from the environment and economize rather than of taking more. A few methods we could preserve and conserve potential are working with wind or solar power when restoring even bring up to date constructed dwelling, making waste materials suitable for reuse, and  living an easier life in balance.

Plants

Plants begin their lives in the form of seeds. The embryo inside the seed is considered as the next sexual generation of plants. Seed germination is an important phase in plant's life. Successful seed germination is vital in every reproducing species in order to perpetuate itself. By definition seed germination is when the dry seeds shed from its parent plant, takes up water and is completed when the embryonic root visibly emerges through the outer structure of the seed (seed coat) (Hasanuzzaman et., al. 2013). Bewley (1997) described that it includes different events that commence with the uptake of water by the quiescent dry seed and terminate with the elongation of the embryonic axis. The visible sign that germination is complete is usually the penetration of the structures surrounding the embryo by the radicle (radicle protrusion). Several authors had reported the importance of germination in the life cycle of plant. According to Hubbard et., al (2012) this stage in the life cycle of the plant is considered as a critical event as germination is the first step in determining the survival rate of the crop thereby affecting its productivity. Meanwhile Donohue et., al. (2010) reported that seed germination is an important developmental phase change in the plant life cycle, which plays critical roles in seedlings establishment and consequently in environmental adaptation. The process of seed germination involves several complex processes and activation of the seeds metabolic pathways which eventually leads to the emergence of newly grown generation of plants. Many of the specific biochemical and physiological processes which characterize germinating seeds, particularly those occurring in storage organs, are special during this stage (Bewley and Black 1994). Knowledge of the germination process and of the seedling establishment and development, involving morphological, physiological, biochemical as well as molecular mechanisms and features is of essential importance for taxonomic, ecological and agronomic studies of certain plants. There are several different gene expression that underlies plant development, the relative specificity of these processes suggests that distinct gene sets are activated and repressed during this stage. The reaction between activation of essential enzymes, sequential release of hormones and the energy relations of the process during seed germination are very significant in understanding the appropriate establishment of plant for its adaptation. Identifying these genes and defining mechanisms involved in regulating their expression will aid in understanding the control of germination-specific mechanisms. This review will provide an overview on the mechanism of gene expression in mainly in angiosperm plant. The different genes expressed in embryos and seedlings will also be tackled A brief description of on the hormonal changes and hormonal balance that triggers or promotes gene expression during germination is also discussed in this paper.

Integrating a Drinking and Drug History into a Psychosocial Assessment essays

Integrating a Drinking and Drug History into a Psychosocial Assessment essays Health and Education Services (HES), Inc., is an agency located in Haverhill, MA. This specific agency provides a wide range of community based mental health and substance abuse assistance. As a student intern from Boston University, the therapist's primary intern responsibilities include the provision of individual and family therapy sessions. The intern has over 10 years of experience doing a wide range of social service work in the community. The client was assigned for psychosocial assessment and to provide ongoing individual therapy sessions. The initial interview was conducted in a small, private office with no windows at the community mental health center at HES. The client is a Hispanic male and the initial questionnaire regarding alcohol/drug issues indicated that he had problems with both cocaine and alcohol. The main presenting problem for the client appears to be the alcohol issues, which have cost him his job and are in danger of costing him his family as well. His wife and children will be leaving the home if the man does not get some help for his problem.

Treatment strategies that are psychosocial in nature, such as cognitive behavioral, behavioral, motivational interviewing, and family therapy techn...

Battle of Thermopylae in the Persian Wars

Battle of Thermopylae in the Persian Wars The Battle of Thermopylae is believed to have been fought in August 480 BC, during the Persian Wars (499 BC-449 BC). Having been turned back at Marathon in 490 BC, Persian forces returned to Greece ten years later to avenge their defeat and conquer the peninsula. Responding, an alliance of Greek city-states, led by Athens and Sparta, assembled a fleet and an army to oppose the invaders. While the former engaged the Persians at Artemisium, the latter assumed a defensive position at the narrow Pass of Thermopylae. At Thermopylae, the Greeks blocked the pass and beat back Persian assaults for two days. On the third, the Persians were able to flank the Greek position after being a shown a mountain path by a Trachinian traitor named Ephialtes. While the bulk of the Greek army retreated, a force of 300 Spartans led by Leonidas I as well as 400 Thebans and 700 Thespians remained to cover the withdrawal. Attacked by the Persians, the Spartans and Thespians famously fought to the death. Advancing south after their victory, the Persians captured Athens before being defeated at Salamis that September. Background Having been turned back by the Greeks in 490 BC at the Battle of Marathon, the Persians elected to begin preparing a larger expedition to subjugate Greece. Initially planned by Emperor Darius I, the mission fell to his son Xerxes when he died in 486. Intended as a full-scale invasion, the task of assembling the necessary troops and supplies consumed several years. Marching from Asia Minor, Xerxes intended to bridge the Hellespont and advance on Greece through Thrace. The army was to be supported by a large fleet which would move along the coast. As a previous Persian fleet had been wrecked off Mount Athos, Xerxes intended to build a canal across the mountains isthmus. Learning of Persian intentions, the Greek city-states began making preparations for war. Though possessing a weak army, Athens commenced building a large fleet of triremes under the guidance of Themistocles. In 481, Xerxes demanded tribute from the Greeks in an effort to avoid war. This was refused and the Greeks met that fall to form an alliance of the city-states under the leadership of Athens and Sparta. United, this congress would have the power to dispatch troops to defend the region. Greek Plans With war nearing, the Greek congress met again in the spring of 480. In the discussions, the Thessalians recommended establishing a defensive position at the Vale of Tempe to block the Persians advance. This was vetoed after Alexander I of Macedon informed the group that the position could be flanked through the Sarantoporo Pass. Receiving news that Xerxes had crossed the Hellespont, a second strategy was put forward by Themistocles which called for making at stand at the pass of Thermopylae. A narrow passage, with a cliff on one side and the sea on the other, the pass was the gateway to southern Greece. Battle of Thermopylae Conflict: Persian Wars (499-449 BC)Dates: 480 BCArmies Commanders:PersiansXerxesMardoniusapprox. 70,000GreeksLeonidas IDemophilusThemistoclesapprox. 5,200-11,200 menCasualties:Greeks: approx. 4,000 (Herodotus)Persians: approx. 20,000 (Herodotus) The Greeks Move This approach was agreed to as it would negate the Persians overwhelming numerical superiority and the Greek fleet could provide support in the Straits of Artemisium. In August, word reached the Greeks that the Persian army was nearing. The timing proved problematic for the Spartans as it coincided with the feast of Carneia and the Olympic truce. Though the de facto leaders of the alliance, the Spartans were prohibited from engaging in military activity during these celebrations. Meeting, the leaders of Sparta decided that the situation was significantly urgent to dispatch troops under one of their kings, Leonidas. Moving north with 300 men from the royal guard, Leonidas gathered additional troops en route to Thermopylae. Arriving, he elected to establish a position at the middle gate where the pass was the narrowest and the Phocians had previously built a wall. Alerted that a mountain trail existed that could flank the position, Leonidas dispatched 1,000 Phocians to guard it. In mid-August, the Persian army was sighted across the Malian Gulf. Sending an emissary to negotiate with the Greeks, Xerxes offered freedom and better land in return for their obedience (Map). Fighting at the Pass Refusing this offer, the Greeks were then ordered to lay down their weapons. To this Leonidas reputedly replied, Come and get them. This reply made battle inevitable, though Xerxes took no action for four days. The constricted topography of Thermopylae was ideal for a defensive stand by the armored Greek hoplites as they could not be flanked and the more lightly armed Persians would be forced into a frontal assault. On the morning of the fifth day, Xerxes sent troops against Leonidas position with the goal of capturing the Allied army. Approaching, they had little choice but to attack the Greeks. Fighting in a tight phalanx in front of the Phocian wall, the Greeks inflicted massive losses on the attackers. As the Persians kept coming, Leonidas rotated units through the front to prevent fatigue. With the failure of the first assaults, Xerxes ordered an attack by his elite Immortals later in the day. Surging forward, they fared no better and were unable to move the Greeks. The next day, believing that the Greeks had been significantly weakened by their exertions, Xerxes attacked again. As on the first day, these efforts were turned back with heavy casualties. A Traitor Turns the Tide As a the second day was coming to a close, a Trachinian traitor named Ephialtes arrived in Xerxes camp and informed the Persian leader about the mountain trail around the pass. Taking advantage of this information, Xerxes ordered Hydarnes to take a large force, including the Immortals, on a flanking march over the trail. At daybreak on the third day, the Phocians guarding the path were stunned to see the advancing Persians. Attempting to make a stand, they formed on a nearby hill but were bypassed by Hydarnes. Alerted to the betrayal by a Phocian runner, Leonidas called a council of war. While most favored an immediate retreat, Leonidas decided to stay at the pass with his 300 Spartans. They were joined by 400 Thebans and 700 Thespians, while the remainder of the army fell back. While there are many theories regarding Leonidas choice, including the idea that Spartans never retreated, it was most likely a strategic decision as a rearguard was necessary to prevent the Persian cavalry from running down the retreating army. As the morning progressed, Xerxes began another frontal assault on the pass. Pushing forward, the Greeks met this attack at a wider point in the pass with the goal of inflicting maximum losses on the enemy. Fighting to the last, the battle saw Leonidas killed and the two sides struggle for his body. Increasingly overwhelmed, the surviving Greeks fell back behind the wall and made a last stand on a small hill. While the Thebans ultimately surrendered, the other Greeks fought to the death. With the elimination of Leonidas remaining force, the Persians claimed the pass and opened the road into southern Greece. Aftermath Casualties for the Battle of Thermopylae are not known with any certainty, but may have been as high as 20,000 for the Persians and around 2,000-4,000 for the Greeks. With the defeat on land, the Greek fleet withdrew south after the Battle of Artemisium. As the Persians advanced south, capturing Athens, the remaining Greek troops began fortifying the Isthmus of Corinth with the fleet in support. In September, Themistocles succeeded in winning a critical naval victory at the Battle of Salamis which forced the bulk of Persian troops to withdraw back to Asia. The invasion was brought to an end the following year after the Greek victory at the Battle of Plataea. One of the most famous battles of this time period, the story of Thermopylae has been recounted in numerous books and films through the years.

Final paper - Movie Review Example The role of violence in the film is to establish and to preserve power, on the one hand, and to defend the helpless from power-greedy individuals and groups, on the other hand. The film establishes this role through the construction of the nature and ends of violence by using the elements of storytelling, cinematography, music, and editing, while the effect of these scenes on the audience is to help them realize the positive and negative uses of violence, as they witness how the cultural historical background of China demonstrates the conflict between Chinese and American cultures through the conflicts between autonomy and domination. The film uses violence to how some people use violence to impose their authority and to oppress marginalized people for economic purposes. The storyline has a chronological timeline and plot that revolve around the time of transition in China, from being a closed to being an open-market society that is vulnerable to Western and local exploitation. The timeline simplifies the presentation of the story with a clear ending, middle, and ending. Continuity editing helps the audience understand the causes and effects of violence on the Chinese society. In the film, the British use their guns to show their power over the Chinese. An example is what happened to Wong’s patient who got shot. Wong says that the patient got into the wrong ship because he got confused with the flags, so the British shot him. The low angle shot shows how Wong is in a strong moral position because he helps heal those who are victims of violence.
