Upton Hall School Essay The purpose of a trailer is to persuade the viewers to go and see a specific film that it is advertising. A trailer is an overview of a forthcoming movie due for release at a cinema, DVD or video, which attracts the audiences attention. The trailer for Moulin Rouge is targeted at audiences over 12. This age certificate is set by the British Film Censors Board. It persuades people to go to watch the film as awarding actors, actresses and film director are in this movie. For example Baz Luhrmann the director has directed many other accredited movies including Rome Juliet and Strictly Ballroom, therefore Moulin Rouge will appeal to Baz Luhrmann fans (synergy). The genre of this film is a musical love story set in late 19th century Paris at the Moulin Rouge, meaning it is a fast and exciting trailer which creates tension and suspense for the audience. The main characters in the trailer for Moulin Rouge are Satine (played by Nicole Kidman) the courtesan and main protagonist for both the passionate filled playwright Christian (played by Ewer McGregor) and the lovelorn Duke (played by Richard Roxburgh). Another character shown in the film is Zidler (played by Jim Broadbent) the master of ceremonies at the Moulin Rouge. Besides the main characters of the film, also present in the trailer are performances by dancers, jugglers, and acrobats at the fabulous sensuous nightclub Moulin Rouge. The Moulin Rouge trailer shows the films potential through the film language used. It uses sound, lighting, colour, editing and camera movements to its advantage so the audience wants to see this film. This moving romantic journey is set in and around the mesmerising extravagance of the Moulin Rouge. It is set in the late 19th century in Paris, a time of change and excitement. The director has chosen to set this film in Paris as it compliments the story. Paris is known as the city of love and romance paralleling the theme of the film. By setting the movie in a familiar place it adds to the affect as the audience can relate more to the story. In the 5th shot of the trailer it shows a view of Paris including the Eiffel Tower and the Moulin Rouge. This allows the audience to be able to become more involved in this trailer by this use of clever imagery of the city. This persuades the viewers to go and see the film. Baz Luhrmann, the director has chosen to use Mise-En-Scene (costume, hair and make-up) as a major part of this film all of which are, bright, colourful and eye-catching drawing the audience to the excitement and passion of the Moulin Rouge. Each character has their own individual style which represents their personality and beliefs; Satines period costume hair and make-up are very sensuous and revealing drawing the audience to her. The colours used in the costumes are all dramatic e. g. red, black and purple which convey a strong and mysterious character. These colourful bright costumes are set against Satines pale translucent and vibrant red hair, giving her a very dramatic appearance. In contrast Christians costumes are very plain ordinary clothes of the late 19th century period. The Duke although wearing similar clothes to Christian his clothes look more expensive and he wears a top hat. He has waxed moustache and like the archetype villain, he strokes his moustache when he is being particularly evil and malvolant. By using the difference costumes for each character the audience quickly develop relative feelings and perceptions towards them. This is a very persuasive piece of film language the director has chosen to use, as this makes the audience more interested in the film trailer so they will want to go and see the whole movie. Another part of Mise-En-Scene in this rapid montage of shots is how props are used to persuade the audience to watch the movie. Trapeze swings and dance choreography are all part of props which are used to interest the audience, conveying the excitement and energy inside the exotic nightclub. In the 13th frame Satine is suspended on a trapeze swing as she performs to the men below. As she performs not only does this create excitement and enjoyment for the male audience below but it creates tension and excitement for the audience watching the trailer arousing their interest. This use of props are used to persuade the viewers to go and see the full blockbuster hit. The film maker has chosen to use body language to create relationships between characters. Characters who like one another have their bodies closer together, for example Satine and Christian are lovers meaning their bodies are closer and the shot is more intimate. The audience are made to feel extra comfortable around the couple where as between the Duke and Christian this shot is more aggressive and powerful. Satine is very confident when performing and when she is with Christian but when she is featuring in a shot with the Duke, she is timid and turns away from him. This shows to the audience her true feelings about the Duke. Christian is less confident and timid but as the trailer continues his confidence grows, as his love for Satine develops. The audience can develop relationships with characters depending on the characters actions. If relationships between the audience and characters can be formed in a 3 minute trailer, it is more likely the audience will be persuaded to go and watch Moulin Rouge at the cinema. The lighting and colour the director has chosen to use is very atmospheric and creates a feeling of tension and excitement for the viewer throughout this trailer. The lighting and colour reflects the characters personality, action and feelings, which influence the audience into a feeling a certain way. The trailer consists of around 120 shots all of which are in colour. Almost all the shots are set inside the Moulin Rouge where the lighting is from above showing down on those people below. This lighting effect is known as high key lighting. The Duke is always set in low key lighting as this creates harsh shadows over his face. In one frame in particular part of the Dukes face is in shadow whilst the other half of his face is in a spotlight. By using harsh lighting when the Duke is in the frame it adds to the effect and conveys to the audience he is an evil and dangerous character. When Satine and Christian are together lighting is soft and intimate to reflect their loving feelings for each other. High key lighting is used here as it looks natural. This is achieved with filter lighting. The lighting conveys a loving and caring mood compared to the evil and aggressive Duke. In trailer there are two main types of sounds; diegetic and non-diegetic sound. Diegetic is sound which is part of the film world which the characters can hear. This can be in the form of dialogue, music, or sound effects which come from a source in the movie. This can occur on or off screen: the audience can see what is making the sound (on screen) or they cannot (off screen). Non-diegetic is sound which the characters cannot hear. This can be background music, voice over or narrative. Only the audience hear non-diegetic sound. In this trailer for Moulin Rouge diegetic sound is used; dialogue between characters, gun shot and music. In the 30 second shot Satine is singing in the play but then this diegetic sound turns into non-diegetic sound, as different frames continue whilst the singing (which the characters in this frame cannot hear) continues. This is what makes the trailer more unique and appealing for the viewers. Another example of diegetic sound used very often in the Moulin Rouge trailer is dialogue between character for e. g. Satine and Zidler appear on one shot together where they are discussing the Duke. Having a variation of diegetic sounds persuades the audience to go and see the film. Non-diegetic sound is used in the Moulin Rouge trailers. Examples of non-diegetic sound are the narrator, Christian (the second main narrator) and background music, all of which are sounds the characters do not hear. Non-diegetic sound is sound which the viewers do not recognise as part of the film world. In this case popular non-diegetic sounds are the narrators. Christian is a character in the film but he is also a main narrator. He occasionally speaks over shots giving the audience a short synopsis of the storyline to arouse their interest, so they will want to go and watch the full length feature film. An example of narrative speech Christian says is this story is about love. at the Moulin Rouge.

2 Samuel 12 1-31 Essay -- Scripture Analysis

2 Samuel 12 1-31 The story line begins with God sending Nathan the prophet. Who is Nathan the prophet. He is described as a messenger, a courtroom advisor a man of great integrity. A man firm in his faith to God, his social status Places him in the position to know the inner working of the royal household and with revelation from God. Nathan is skilled, faithful and willing to serve a powerful Prophetic message from God. In today’s account Nathan would be looked upon as a role model. Nathan techniques would describe him to be a great storyteller. The bible tells us Nathan, served King David and his son King Solomon. There are three major revelation accounts Nathan was involved in expressing God’s message. 1. "A House For My Name† 2 Samuel 7:4-7,12-13 2. "You Are The Man!"2 Samuel 12:1-9 3.

Esterification

To synthesis ecstatically acid by stratification. Introduction: A pleasant, often fruity, odor is characteristic of some of the simpler esters. Ethyl butyrate smells similar to pineapples, the odor of n-propel acetate is reminiscent of pears and isopleths acetate has a strong banana fragrance. Esters are derivatives of the carboxylic acids and contain the following functional group: The synthesis of an ester can be accomplished in one of several ways. An stratification occurs when an alcohol and a carboxylic acid are reacted in the reserve of a mineral acid catalyst, such as sulfuric acid.Because these reactions result in an equilibrium mixture of both products and reactants, the reaction conditions must be manipulated in order to produce a reasonable yield. A large excess of one of the reactants can be used in the starting mixture or alternatively, one of the products can be removed as the reaction proceeds (as by a distillation), to shift the equilibrium to the right. Other synthet ic pathways to esters also exist. Acid chlorides react with alcohols to yield an ester and hydrochloric acid.A small amount of pyridine is usually deed to the reaction mixture to neutralize the resulting acid. Acid anhydride can also react with alcohols to produce esters. Unlike the reactions between carboxylic acids and alcohols, neither of these two methods for preparing esters results in an equilibrium mixture. Ecstatically acid, or aspirin, is one of the most widely used and versatile drugs known today. It was first synthesized by Charles von Gerhardt in 1 853 and was later patented by a German dye chemist named Frederica Brayer in 1893 who recognized its potential as an analgesic (pain reliever).Salicylic acid, a impotent of willow and poplar bark, had been used as a pain killer for centuries, but its highly acidic property caused irritation of the mucous membranes of the mouth and throat and also resulted in uncomfortable gastric pain. By transforming the acidic phenol functio nality into an ester group, the compound retained its analgesic properties but lost some of its irritating side- effects. In addition to relieving pain, aspirin is also an antipathetic (fever reducer) and an anti-inflammatory agent (used for arthritis). Like all drugs, aspirin also has some undesirable side effects which should be tote.When taken in large quantities (several grams per day), gastric problems can result. Its use has been implicated in Rexes syndrome, a brain disorder that can affect people under the age of 18. Some people are highly allergic to aspirin. Finally, aspirin interferes with platelets and affects normal blood clotting which can lead to hemorrhaging in extreme cases. However, its anticoagulant properties can also be used to advantage in preventing blood clots from forming in the arteries. Recent studies have shown that the consumption of one half of an aspirin tablet per day can help to prevent heart attacks and strokes.Aspirin can be synthesized by the stra tification of salicylic acid via reaction with acetic anhydride. A few drops of phosphoric acid are added to serve as a catalyst for the reaction. The use of acetic anhydride as a reactant, instead of acetic acid, results in a rapid and irreversible conversion of salicylic acid to ecstatically acid. Experimental Procedure: Synthesis of ecstatically acid 1 . A 400 ml beaker containing about 150 ml of water was heated to the boiling point on a hot plate. 2. 2 g of salicylic acid was weighed out and it was placed in a 100 ml conical flask. . 5 ml of acetic anhydride was added into the conical flask. . 5 drops of 85% phosphoric acid, HAPPY was added. The flask was swirled to mix the reactants and then it was clamped in the boiling water bath. It was heated for about 8 minutes. 5. The flask was removed carefully from the hot water bath and the hot plate was turned off. 2 ml of distilled water was added cautiously to the flask. The water will react with any unrelated acetic anhydride whic h remains. 6. Once the reaction between acetic anhydride and water had subsided, 40 ml Of water Was added to the flask. 7. The contents was allowed to cool at room temperature for minutes then the flask was placed in ice. . The contents was stirred with a glass rod periodically during this cooling period. The solid product was collected by vacuum filtration and it was washed with cooled water. 9. A small portion (spatula-tip full, 20-30 MGM) of this crude ecstatically acid was set aside. 10. To recitalist the ecstatically acid, it was transferred to a 100 ml conical flask and 10 ml of 95% ethanol was added. 1 1. The flask was heated slowly on a hot plate just until the aspirin completely dissolved. As soon as all of the solid has dissolved, the flask was removed from the hot plate. 12.Water was added to the solution in 5 ml portions, it was swirled after each addition, until a total of 40 ml of water has been added. 13. The flask was placed in an ice bath for 10 minutes to complete the crystallization. 14. The purified aspirin was collected by vacuum filtration. The crystals was washed in the funnel with ice-cold water. The vacuum was left on for a few minutes to air dry the purified aspirin, the crystals was then pressed between two pieces of filter paper to thoroughly dry them. 5. The mass, yield and melting point of dried aspirin were obtained. Results: Weight of salicylic acid used: 2. 0021 g Weight of watch glass: 20. 536 g Weight of watch glass t product: 21. 6651 g Weight of product: 1. 3115 g no. Of mole of salicylic acid: = 0. 01450 mol Volume Of acetic anhydride used 5 ml Density of acetic anhydride = 1. 082 g/ml Mass of acetic anhydride used = 1. 082 g/ml x 5 ml = 5. 41 g no. Of mole of acetic anhydride: – 0. 0530 mol = 3. 66>1 Since the mol of salicylic acid is smaller than the mol of acetic anhydride, salicylic acid is a limiting agent. Mol of salicylic acid produced 1 mol of ecstatically acid. 0. 01450 mol of salicylic acid produced 0. 014 50 mol of ecstatically acid. Theoretical weight of ecstatically acid: 0. 1450 mol x 180. 16 gnu-mol = 2. 6123 g Percentage yield: x 100% = 50. 20 % 50 % Melting point of aspirin: 138 – 140 co Discussion: Aspirin is an effective analgesic (pain reliever), antipathetic (fever reducer) and anti-inflammatory' agent and is one of the most widely used non-prescription drugs. The active ingredient in aspirin was found to be salicylic acid. The structure of salicylic acid is shown below. In this experiment, aspirin is formed from the reaction between salicylic acid and acetic anhydride through stratification. Aspirin can be made by reacting salicylic acid with acetic acid in the presence of an acid catalyst.The phenol group on the salicylic acid forms an ester with the carboxylic group on the acetic acid. However, this reaction is slow and has a relatively low yield. If acetic anhydride was used instead of acetic acid, the reaction will be much faster and has a higher yield (since ac etic anhydride is much more reactive than acetic acid). Therefore, we used acetic anhydride for shorten the period f stratification. In order for reaction to occur faster, phosphoric acid was added as a catalyst. Then the solution was being placed in the hot water bath to heat up and thus triggering the reaction between salicylic acid and acetic anhydride.The reaction was shown as below: In this experiment, the salicylic acid is the limiting reactant and the acetic anhydride is in excess. The addition of distilled water into the mixture after it is being removed from the water bath is to let the water react with the remaining acetic anhydride in the mixture which are still not being reacted. A vigorous reaction will occur as the decomposition of the excess acetic anhydride is exothermic. Once the decomposition of the excess acetic anhydride has completed, more water was added, forming completing the reaction.Now the solution contains two kinds of products, which are ecstatically aci d and acetic acid, according to the reaction shown below. The reason why acetic acid is dissolved in this process but not ecstatically acid was due to the hydrogen bonding of acetic acid can form with water while ecstatically acid cannot. This is due to the large carbon group maintained by ecstatically acid which caused it to have difficulties from forming hydrogen bond with water. The aspirin collected will then be purified by rationalizations. In this purification method, the crude aspirin will be dissolved in a small amount of warm ethanol.Water was then be added and the solution was cooled slowly in the ice bath and then chilled. The ecstatically acid will recitalist, and the solid impurities (unrelated salicylic acid) should remain dissolved in the solution. The solid aspirin will again be collected using vacuum filtration. Rationalizations was needed to obtain a pure product from the crude product. Therefore, this aspirin should be more pure than the original aspirin. The fina l product was left in air dry and weighed. The theoretical and percentage yield was calculated. The weight of ecstatically acid obtained was 1. 115 g while the percentage yield of product was 50%. Besides, the melting point of ecstatically acid we obtained was in the range of 1 38 – 140 By comparing these observed melting points with the literature value of 138 – CHIC for ecstatically acid, it was found that the values were exactly the same, indicating that both rodents were ecstatically acid( previously stated as ecstatically acid and acetic acid). The above reaction was an example of an organic synthesis called stratification. Stratification is the acid catcalled reaction of a carboxylic (-COHO) group and an -OH group of an alcohol or phenol to form a carboxylic ester.In the synthesis of aspirin, the -OH group is the phenol OH group attached to ring of the salicylic acid. The acetic group, ;COACH comes from acetic anhydride, and the reaction is catcalled by phosphori c acid, HAPPY. Salicylic acid has a higher priority as it has a benzene ring which s more stable than the open chain of acetic anhydride because it has more resonance. Salicylic acid reacts better with acetic anhydride than acetic acid, so acetic acid will provide the acetic group which will react with the alcoholic – OH group on the salicylic acid.The hydrogen ion from the hydroxyl group in the salicylic acid breaks away first, then combines with the oxygen which has a negative charge after acetic anhydride is broken into two parts, which are an alkyl carbonyl group and -?CHOC- group. This is how acetic acid is formed. Later on, the alkyl carbonyl group of acetic anhydride which now has positive charge due to the lack Of oxygen atom, connects to the oxygen atom which has a negative charge, lastly produced ecstatically acid as a neutral compound product.The mechanism of how an ecstatically acid formed from stratification reaction will be shown: Precaution steps: 1 . When hand ling phosphoric acid, students should be aware of spill it out because it is corrosive. 2. When adding water to the heated solution, students should be careful and added in small amount of water because it may splatter to the surroundings due to the vigorous reaction. 3. The elution was allowed to cool at room temperature before putting it into the ice bath for the process of crystallization in order to get crystals in a nicer form and in correct manner.

Null Hypothesis Definition and Examples

In a scientific experiment, the null hypothesis is the proposition that there is no effect or no relationship between phenomena or populations. If the null hypothesis is true, any observed difference in phenomena or populations would be due to sampling error (random chance) or experimental error. The null hypothesis is useful because it can be tested and found to be false, which then implies that there is a relationship between the observed data. It may be easier to think of it as a nullifiable hypothesis or one that the researcher seeks to nullify. The null hypothesis is also known as the H0, or no-difference hypothesis. The alternate hypothesis, HA or H1, proposes that observations are influenced by a non-random factor. In an experiment, the alternate hypothesis suggests that the experimental or independent variable has an effect on the dependent variable. How to State a Null Hypothesis There are two ways to state a null hypothesis. One is to state it as a declarative sentence, and the other is to present it as a mathematical statement. For example, say a researcher suspects that exercise is correlated to weight loss, assuming diet remains unchanged. The average length of time to achieve a certain amount of weight loss is six weeks when a person works out five times a week. The researcher wants to test whether weight loss takes longer to occur if the number of workouts is reduced to three times a week. The first step to writing the null hypothesis is to find the (alternate) hypothesis. In a word problem like this, youre looking for what you expect to be the outcome of the experiment. In this case, the hypothesis is I expect weight loss to take longer than six weeks. This can be written mathematically as:  H1: ÃŽ ¼ 6 In this example, ÃŽ ¼ is the average. Now, the null hypothesis is what you expect if this hypothesis does not happen. In this case, if weight loss isnt achieved in greater than six weeks, then it must occur at a time equal to or less than six weeks. This can be written mathematically as: H0: ÃŽ ¼ ≠¤ 6 The other way to state the null hypothesis is to make no assumption about the outcome of the experiment. In this case, the null hypothesis is simply that the treatment or change will have no effect on the outcome of the experiment. For this example, it would be that reducing the number of workouts would not affect the time needed to achieve weight loss: H0: ÃŽ ¼ 6 Null Hypothesis Examples Hyperactivity is unrelated to eating sugar is an example of a null hypothesis. If the hypothesis is tested and found to be false, using statistics, then a connection between hyperactivity and sugar ingestion may be indicated. A significance test is the most common statistical test used to establish confidence in a null hypothesis. Another example of a null hypothesis is Plant growth rate is unaffected by the presence of cadmium in the soil. A researcher could test the hypothesis by measuring the growth rate of plants grown in a medium lacking cadmium, compared with the growth rate of plants grown in mediums containing different amounts of cadmium. Disproving the null hypothesis would set the groundwork for further research into the effects of different concentrations of the element in soil. Why Test a Null Hypothesis? You may be wondering why you would want to test a hypothesis just to find it false. Why not just test an alternate hypothesis and find it true? The short answer is that it is part of the scientific method. In science, propositions are not explicitly proven. Rather, science uses math to determine the probability that a statement is true or false. It turns out its much easier to disprove a hypothesis than to positively prove one. Also, while the null hypothesis may be simply stated, theres a good chance the alternate hypothesis is incorrect. For example, if your null hypothesis is that plant growth is unaffected by duration of sunlight, you could state the alternate hypothesis in several different ways. Some of these statements might be incorrect. You could say plants are harmed by more than 12 hours of sunlight or that plants need at least three hours of sunlight, etc. There are clear exceptions to those alternate hypotheses, so if you test the wrong plants, you could reach the wrong conclusion. The null hypothesis is a general statement that can be used to develop an alternate hypothesis, which may or may not be correct.
