Technology In The Film Industry Essay - 1914 Words

Introduction The film industry has continuously changed since its inception due to rapid technology advancements. Camera technology has been a key factor that has influenced the growth of filmmaking. The first motion picture in the world was produced in the early 1880s, and the first public screening occurred ten years later. It didn’t take long for the quality of films to improve as new filmmaking equipment emerged. Ever since the first movie was produced, the film industry has been continuously changing in response to emerging filmmaking technology. Introduction of digital photography and digital data storage along with the development of internet significantly influenced the film industry (Barsam, 2015). These technologies contributed†¦show more content†¦Digital technology has erased the boundaries and offered new opportunities for shooting films. Shooting with digital cameras tends to be easier as filmmakers can shoot more scenes in less time. Often, multiple digital cameras can be used on the same shot but in different angles which assists in reducing the number of retakes. Digital shooting allows filmmakers to shoot multiple takes and in different angles at fewer costs (Murray, 2012). With new steady camera equipment, the footage shot is more precise and intimate. This enhances the audience experience as the camera view is authentic. Also, the cameras save time wasted on reshooting the same scene. IT has also changed the way movies are shot particularly through application of film special effects. The film industry heavily relies on illusions to simulate imaginary events in a story (McClean, 2007). Computer Generated Imagery (CGI) is another key technology that is applied to special effects to enhance films. CGI is mainly used in special effects to enable filmmakers to control the scenes instead of using many extra actors. This has simplified film production and reduced the costs incurred. A lot of movies especially those classified under fiction, action, and horror genres rely on CGI. Post-Production Previously, editing used to be a challenge for most filmmakers. Often, they relied on manual methods when filming to add effects to the films. Incorporating visual effects to the film was a demanding task thatShow MoreRelated Digital Film Technology Revolutionizes the Film Industry Essay1334 Words   |  6 PagesDigital Film Technology Revolutionizes the Film Industry       With the release of Star Wars: Episode I the Phantom Menace, in March of 1999, digital film technology officially filtered itself in to main-stream Hollywood.

The History of Coca-Cola Essay - 1106 Words

Coca-Cola’s attempt to market their new tasting product â€Å"New Coke†, made the company understand that, the original is sometimes different enough. In 1886, Doctor John Pemberton, invented the Coca-Cola formula in a brass kettle in his backyard. The name â€Å"coca-cola† was suggested by Pemberton’s bookkeeper. In fact, this bookkeeper scripted â€Å"coca cola† with flowing letters, which is the popular logo of today. The soda was brought to the public eye in 1886. In 1887, Asa Candler bought Coca Cola from Pemberton for $2,300. Pemberton died a year later. Candler’s aggressive marketing skills made Coca Cola one of America’s most popular soft drinks. Between 1890 and 1900, sales increased by over 400 percent. The drink was sold across the United†¦show more content†¦Big things were happening for Coca-Cola, although the biggest were to come. Roberto Goizueta applied for a job in a Cuban newspaper, seeking a chemical enginee r at Coca-Cola. In 1960, Goizueta and his wife came to the U.S. with $40 and 100 shares of Coca-Cola. He was placed in Atlanta in 1964, were after only 4 years, he got promoted to vice president of research and development (Roberto). In May 1980, after the resignation of J. Lucian Smith. Goizueta was chosen president. Once he was chairman, he made major strategic decisions to try and benefit the Coca-Cola company. The first was the type of sweetener, instead of ordinary sugar; Goizueta allowed the use of high-fructose corn syrup, this was 40 percent cheaper. Many more good ideas came about because of Goizueta including, Diet coke, and the slogan â€Å"Coke it is.† After many good decisions, the bad one had to be made. After 99 years of Coca-Cola’s original formula, they decided to change its beloved taste, but why? In the 1980’s, Coca-Cola, found it self-loosing the consumer war with Pepsi. The only thing keeping Coca-cola from loosing money, was simply the availability of the product.

Equipment For Operation Iraqi Freedom And Operation...

STATEMENT OF THE PROBLEM What were the causes for the excess and the abandonment of equipment for Operation Iraqi Freedom and Operation Enduring Freedom? BACKGROUND Most logistical tacticians have a tendency to review historical documents before developing strategies to deploy and redeploy troops and equipment. This common practice is very successful to deploying soldiers and equipment, but historically there is a lack of emphasis on the redeployment, or retrograde of equipment. The soldiers are undoubtedly brought home; nonetheless antiquity shows us equipment is sometimes not a priority to return. Logistic American retrograde issues were first publically noticed in 1847 following war with Mexico. A published Army bulletin revealed property divesting as an issue and needed a high priority because of the great loss of left behind equipment. Again after World Wars I and II, the military had immense amounts of equipment scattered across the Pacific and Europe. There was no specific need for the equipment after the war, and much of it was abandoned in place, and although lack of retrograde operations occurred, the abandoned equipment turned useful in supporting the Korean War. Logisticians learning their lessons from previous wars, vowed to not be unprepared while entering the Vietnam War.

Determining the limiting reactant and the percent yield i a precipitation reaction free essay sample

One example of a double replacement (metathesis) reaction is the mixing of two solutions resulting in the formation of a precipitate. In solution chemistry, the term precipitate is used to describe a solid that forms when a positive ion (cation) and a negative ion (anion) are strongly attracted to one another. In this experiment, a precipitation reaction will be studied. Stoichiometry will then be used to investigate the amounts of reactants and products that are involved. The word stoichiometry is derived from two Greek words: stoicheion (meaning â€Å"element†) and metron (meaning â€Å"measure†). Stoichiometry is an important field of chemistry that uses calculations to determine the quantities (masses, volumes) of reactants and products involved in chemical reactions. It is a very mathematical part of chemistry. In this experiment, you will react a known amount of sodium carbonate solution with a known amount of calcium chloride solution. The skeletal (unbalanced) equation for the resulting double replacement reaction is: Na2CO3(aq) + CaCl2(aq) ? NaCl(aq) + CaCO3(s) Note that three of the chemicals have their states or phases designated as (aq) and one is designated as (s). The (aq) represents the term aqueous which means that the substance is soluble and dissolved in water. The (s) means that the substance is a solid (in this case, it is a precipitate). Precipitate formation is easily observed as the mixed solutions turn cloudy and, if desired, the precipitate can be easily separated from the solution by filtering. Since your precipitate will be separated and weighed, you will need to dry the precipitate in a drying oven before measuring its mass. Stoichiometry will then be used to determine the amount of precipitate that should be formed in the reaction. It is often difficult as well as impractical to combine just the right amount of each reactant that is required for a particular reactant that is required for a particular reaction to occur. Given this fact, this experiment is designed so that only one of the reactants will be completely used up. This is called the limiting reactant because it limits the amount of products formed. Since the other reactant will have a quantity remaining, it is called the excess reactant. One of your tasks will be to determine which of your reactants is limiting and which is in excess. The two chemical reactants in this experiment have common uses in our lives. In one solid form, sodium carbonate is known as â€Å"washing soda† and is used to enhance the effectiveness of laundry soap. Calcium chloride solid can act as a desiccant (drying agent) and is used by recreational vehicle owners to remove moisture from the air in the vehicle during winter storage. OBJECTIVES 1. to observe the reaction between solutions of sodium carbonate and calcium chloride. 2. to determine which of the reactants is the limiting reactant and which is the excess reactant. To determine the theoretical mass of precipitate that should form. 4. to compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. MATERIALS Equipment Chemicals Balance 0. 70 M sodiuim carbonate solution, Na2CO3 2 graduated cylinders – 25 mL 0. 50 M calcium chloride solution, CaCl2 3 beakers – 250 mL dH2O wash bottle Filtering apparatus (ring with stand, funnel) Filter paper Drying oven Lab apron Goggles PROCEDURE 1. Put on your lab apron and safety goggles. 2. Obtain two clean, dry 25 mL graduated cylinders and two clean, dry 250 mL beakers. In one of the graduated cylinders measure 25 mL of the Na2CO3 solution. In the other graduated cylinder measure 25 mL of the CaCl2 solution. Record these volumes in your lab notebook. 4. Pour the contents of both graduated cylinders into one of the 250 mL beakers and observe the results. Record these qualitative observations in your notebook. Allow the contents of the beaker to sit undisturbed for 5 min. to see what happens to the suspended solid particles. Meanwhile, proceed to step 5. 5. Obtain a piece of filter paper and put your name on it using a pencil. Weigh and record the mass of the filter paper, then use it to set up a filtering apparatus as shown in Figure 6D-1. 6. Use the wash bottle to lightly wet the filter paper in the funnel to keep the filter paper in place. Swirl the beaker and its contents to suspend the precipitate in the solution, then pour it carefully and slowly into the filter funnel. It takes time to complete the filtering process so plan to do it in stages. Use the wash bottle to rinse the remaining precipitate from the beaker. 7. Use the wash bottle one last time to rinse the precipitate in the filter paper. This will remove any residual NaCl(aq) that remains with the precipitate. 8. After the filtering is complete, remove the wet filter paper containing CaCO3 precipitate and suspend it carefully in the third 250 mL beaker. Put your labeled beaker with filter paper + precipitate in the drying oven for 30-45 min. 9. Remove the beaker with filter paper + precipitate from the drying oven and allow to cool for a few minutes. 10. Weigh and record the mass of the dry filter paper containing the CaCO3 precipitate. 11. Clean up all your apparatus. 12. Wash your hands thoroughly with soap and water before leaving the laboratory. Reagent Disposal Rinse all solutions down the sink with copious amounts of water. Any solids should go into the designated containers. Post Lab Considerations The double replacement reaction in this experiment formed two chemicals which are commonly known to you. The NaCl(aq) is salt water and the CaCO3(s) is a component of some classroom chalks. Using the data collected, you will be able to calculate the moles of each of the chemicals that are added together to react. Then using the principles of stoichiometry you will be able to determine which chemical is the limiting reactant and thereby predict how much precipitate should form. This stoichiometric determination will then be compared to the actual mass of CaCO3(s) formed. Chemists are often concerned with optimal yields in manufacturing a certain chemical. One way of measuring this is to calculate the percent yield of that particular chemical by using this formula: Percent yield = actual mass produced (grams)____ x 100% theoretical mass produced (grams) Include the following information in the results section and data tables: Qualitative observations Quantitative observations Volume of 0. 70 M Na2CO3 solution Volume of 0. 50 M CaCl2 solution Mass of filter paper + dry solid CaCO3 Mass of filter paper ANALYSIS OF RESULTS 1. Copy the chemical equation for the reaction from the introduction and balance it. 2. From your Part I results, calculate the moles of Na2CO3 that were added to the beaker. 3. From your Part I results, calculate the moles of CaCl2 that were added to the beaker. Use your answers from Analysis 1-3 above and stoichiometric principles to determine which chemical is the limiting reactant. 5. Use stoichiometric calculations to determine the theoretical mass of CaCO3 precipitate that should have formed. 6. From your Part II results, calculate the actual mass of CaCO3(s) precipitate that formed. 7. Calculate the percent yield of CaCO3(s). FOLLOW-UP QUESTIONS 1. If you were to evaporate the filtered solution to dryness, would you be left with only solid NaCl? Explain. 2. What theoretical volume of the Na2CO3 solution used in this experiment would result in no excess reactant? 3. A precipitation reaction occurs when 50. 0 mL of 0. 50 M BaCl2(aq) is mixed with 75. 0 mL of 0. 75 M Na2CO3(aq). The only precipitate is the BaCO3(s) formed. a) Write the balanced equation that describes this reaction. b) Which chemical is the limiting reactant? c) Predict the theoretical mass of BaCO3(s) that should form. d) This experiment was conducted and the percent yield was found to be 82%. What was the actual mass of BaCO3(s) that formed?
