Evaluation Analysis Essay Example | Topics and Well Written Essays - 1000 words

Evaluation Analysis - Essay Example Although the movie itself is very simple, the message hidden within the movie is quite deep and intricate (Brown). Every romantic movie needs to have two characters that are deeply in love with each other. They need to have a deep rooted passion and affection for each other. This movie ‘Two can play this game’ fulfills the criteria of being called a romantic comedy because of the chemistry, emotional connection and love that the main characters Shante and Keith hold for each other. Usually in romantic movies, the characters face some obstacles in order to get to their loved one and in this movie also, the characters do face a few difficulties which make the plot more interesting. The name of this movie ‘Two can play this game’ suggests that generally more players are needed for arousing an interest in a game. However, there is a game which only two people can play. And that game is called love. In love, there is no involvement required of other people what so ever. Infact, the involvement of more people actually destroys the game. It inhibits the two lovers from noticing the inherent chemistry between the two of them as was the case with Shante and Keith who are the hero and heroine of the movie. In this way, the movie also builds up the curiosity of the audience as to the nature of that game. The flow of the movie keeps the audience hooked up and provides bouts of humor at intervals. The movie opens with the heroine wearing yellow and a refreshing music playing in the background. She is shown driving her impeccable red convertible and people of the other gender have to hold back emotions because she is so sexy. She does not pay attention to any of them as she continues with her daily schedule. The first scene is dedicated completely to giving credits and providing context to the whole movie. She is shown driving down the city, enjoying the pleasant weather and the environment around her. There is no introduction given

Industrial Salmon Farming Essay Example for Free

Industrial Salmon Farming Essay Fish farming, also known as Aquaculture, is an industry that uses sea life for commercial purposes. One of the most common fish species that are farmed worldwide is salmon. Most of the salmon Americans consume are farmed in British Columbia and grow in open net cages placed directly in the ocean; creating environmental threats in all areas it takes place. The problem with open net cages that are placed directly in the ocean is; the release of ocean harming farm waste, chemicals, and disease. Before these problems can be solved, a look at the salmon net cage industry is needed, along with the environmental impacts. Open cages are not secure in fact many farmed salmon can escape, escapees usually occur during storms or damages made to the net by their predators. According to Oceana.org â€Å"Atlantic Salmon escapes on the U.S. and Canadian west coasts are common; there were 350,000 known escapes in 1997 and farmed Atlantic Salmon have been found thousands of miles away from the closest salmon facilities.† (Farmed Fish Escapes) The problem with escapees is that they are known to travel long ways and carry diseases. Farmers are encouraged to treat farmed salmon with antibiotics sense they are in open net cages in the ocean, and are prone to diseases found in the ocean. Farmed Salmon are sterilized with antibiotics to keep other wild fish safe; the concern with the use of antibiotics in farmed salmon is that many of these antibiotics are also used to treat human diseases. Scientist Cabello works in the department of microbiology says â€Å"the industry continues to rely on these treatments, administered in net-cages open to the ocean, despite growing concerns over antibiotic resistance.†(Cabello) The antibiotics used to treat farmed salmon are becoming resistant to antibiotics making it more difficult to treat human diseases because it allows microbes to become resistant to antibiotic treatments, making it more difficult to treat human disease. (farmedanddangerous.org) Salmon farming in British Columbia can resolved by simply by separating the farmed salmon from the open net cages and into a land facility. Farming salmon on land decreases a lot of health risks, less escapees, and chemical waste. According to David Suzuki founder of The David Suzuki foundation he states â€Å"Evidence shows that land-based, closed-containment aquaculture is an environmentally, technically, and economically viable option to net-pen aquaculture.† (Suzuki) Operating a land-based facility is affordable when it comes down to all costs to the environment; it decreases environmental issues that can be a greater issue in the future. The good news is that in Canada, Washington State, and Tasmania closed containment salmon farming is being practiced (Puresalmon.org). A company that is practicing closed containment farming is AgriMarine, on the website Puresalom.org they examine and state â€Å"will yield all-year-round crops of ecologically sound salmon, raised in environmentally safe [closed] facilities — a first in an entire industry.† (qtd. In AgriMarine) Land-based salmon farms remove the risk of escaped salmon and contamination of the ocean. Open net-cage salmon farms are a se rious threat to the balance of life in the ocean and to wild salmon in particular. The solution is to grow salmon on land facilities it creates a barrier between farmed salmon and the ocean, it helps to protect the ecosystem and wild salmon from the problems caused by industrial salmon farming.

Synthetic Oil Has Four Main Purposes Engineering Essay

Synthetic Oil Has Four Main Purposes Engineering Essay Graphite grease is used to lubricate in high temperature environments. Graphite can dissipate more heat than some other lubricants. For example, graphite grease can often handle more heat than natural bearing grease. Graphite grease is often used on linkages as it can stick to them and will not evaporate like oils do. This lubricates both surfaces and reduces the amount of energy needed to move them. Cutting fluid is used in cutting machinery to keep the cutting tool and the item being milled at a stable temperature, prevent rust forming on the item being milled or the cutting tool, to prolong the life of the cutting head by lubricating the cutting edge and prevent tip welding and to clean away shards of metal caused by the milling of the metal. CNC routers use cutting fluid pumped to the cutting head from a reservoir of cutting fluid. This cutting fluid is usually an oil-water emulsion. The cutting fluid is applied directly at the point of cutting to reduce and keep the temperature of the cutting area stable which is critical when working to small tolerances. The addition of the cutting fluid provides lubrication which in turn lowers the amount of heat generated at the working edge reducing thermal expansion and allowing for a more accurate cut. The reduction in friction also reduces tip welding to the milled part. The application of the cutting fluid coats the head of both the cutting tool and milling area to prevent oxidisation of the new surface being milled and the new surface of the cutting head caused by the wear of the cutting process prolonging the life of the cutting head. The flow of cutting fluid across the cutting surface removes the metal swarf from the area creating a better quality finish to the milled part. These metal shards get removed from the cutting fluid before it gets back to the reservoir by a strainer. This prevents damage to the fluid pump and contamination of the cutting fluid heading back to the milling surface. http://media.insidewoodworking.com/cnc-milling-machine-a1.jpg Question 2 Engine of a family car In a combustion engine of a family car, where the oil is kept is called the sump. This is where the oil pump takes the oil from to distribute it around the engine. The oil then passes through a filter to remove dirt particles from the oil before it gets to the vital parts of the engine. The oil gets distributed around the engine through oil galleries. These oil galleries have spurt holes in them which direct oil to the parts where it is needed such as cylinders and bearings. To maintain this system oil and filter change must be done when the manufacture recommends. To do this you need a new filter, around 4 litters of the correct grade of oil and a new sump plug seal. To start you need to get the engine oil warm to make it thinner. To do this you need to take the car for a drive and get it up to operating temperature. Once it is up to temperatures place it on level ground with the handbrake on and in gear, and jack the front of the vehicle up so you have access to the sump plug. Get a container for the oil to pour in to and undo the sump plug. Once removed, check the magnet on the end of the sump plug for excessive and large chunks of metal which is a sign of engine wear. While the old oil is being drained off remove the oil filter being careful not to spill the oil that will still be in it. To fit a new filter, make sure that a smear of oil is placed around the rubber seal to get a better seal and then screw on until tight. Replace the sump plug gasket and screw the sump plug back into the sump, nipping up with the appropriate tool. Then start filling the engine up with the new oil checking the level on the dipstick. When the oil level reaches in between the two notches it is safe to start the engine and bring it up to temperature. Once it has been run check for oil leaks and the oil level. Positive displacement air compressor The lubrication system of an air compressor uses the dip and splash method. This consists of a hook cast of bolted in to the crankshaft which dips the hook into oil in the sump and brings it back out again causing it to splash oil around the inside of the engine. This system is used because it is cheep and easy to maintain. To maintain the system it is simply a process of undoing the sump plug, letting the oil drain out, putting the sump plug back in and filling up with oil. This system does not have an oil filter and pipe work which is the reason why it is cheep and easy to maintain. http://www.dansmc.com/splash_lube2.jpg Multi-head machining centre Machining centres use multiple lubrication heads and nozzles to get different types of lubrication effects i.e mist and flood. A pump takes pre mixed cutting fluid from a reservoir through a filter to a nozzle which delivers it to the cutting surface. Excess cutting fluid then runs away from cutting area and into an oil catch. At the bottom of this oil catch is a strainer which takes out metal shavings and debris from the cutting fluid that the fluid removed from the milling area. The cutting fluid then falls back to the oil reservoir where it becomes ready to use again. To maintain this system the cutting fluid needs to be renewed as over time it degrades and bacteria colonize within it making it smell and hence becomes a health hazard. Cutting fluid must be disposed of in the correct way because if it is disposed of incorrectly it is harmful to the environment. The reservoir, piping and pump must be cleaned out with disinfectant to kill off the bacterial colonies. The reservoir mus t then be topped up with the correct mixture of cutting oil and water. Question 3 An engine in a red bull air race series plane is subjected to extreme g-force and inversions. For the engine to remain lubricated at all times they cannot use a conventional wet sump due to the inversions that the planes do throughout the course. To combat this they use a dry sump in which the oil is stored in an oil tank, not at the bottom of the engine in an open sump. This oil tank can be any size the manufacturer would like and can be placed anywhere on the aircraft. The oil is collected by a flop tube so the oil can be collected under any amount of g-force or inversion to maintain oil pressure through out the flight. The oil is pumped from the storage tank through oil galleys and spurt holes to lubricate the engines vital parts such as the cylinders, crankshaft and camshafts. The oil then falls to the base of the engine like it does in a wet sump system. The oil collects in an oil pan at the base of the engine and is then pumped to the oil storage tank via an oil cooler. The pum p used for this is a special pump called a scavenger pump which has to be more tolerant of entrained gasses than a standard pressure pump as it will not be constantly sucking oil due to the small amount being used in the engine. This maintains the least amount of oil in the engine at all times. A dry sump system is used in acrobatic planes for a number of reasons. If a conventional wet sump system was used during inversions and changes from positive to negative g-force the oil from the sump would flood the engine causing the engine to cut out and leaving the pilot of the aircraft in difficulties. Changes in direction on the long banked curves found on the red bull air race courses would cause the oil to move to one side of the sump in a wet sump system potentially starving the oil pump causing a drop in oil pressure increasing the risk of serious wear on the engine which could cause engine failure over time. A benefit of using a dry sump is that the engine can be mounted lower down in the aircraft due to not having a deep sump pan so the weight can be kept lower down helping with aerodynamic stability. Another benefit of using this method of lubrication is that the crank shaft cannot become immersed in oil which would reduce the power generated by the engine. This not only makes the plane safer due to there being no risk of fluctuation in power but also means more power can be developed from smaller engines, in some cases up to 15bhp. Overall the dry sump system is vital to the operation of acrobatic aircraft because without it, it would not be able to perform the stunts and acrobatic manoeuvres required in the red bull air race system.

Emotive Response to Essays -- Emotion Essay

In tenth grade, everyone in Mrs. D’s English class had to write an essay on an American author. No one was actually given a choice in the matter, nor was anyone allowed the option of choosing their author. That kind of option wouldn’t have meant much to me anyway, seeing as I, like many sophomores in high school, had no interest in anything even remotely intellectual. Fate’s ubiquitous hand dealt me Sherwood Anderson, a man I had never heard of (nor did I frankly care to know about). Despite the clichà © one might expect at this point, research did nothing to change my apathy towards this essay. I wrote down the standard encyclopedic style biography that defined the efforts of most of my fellow classmates. After all of us were through embarrassing ourselves by reading said biographies in front of the class in the usual self-conscious manner that defines high school presentations, I felt no different. It was clear that Anderson cared deeply about the work that he did in his lifetime, but I certainly didn’t. The self-imposed mediocrity continued uninterrupted by tenth grade English, as I expected. Shortly after this assignment, Mrs. D continued her Tenth grade English syllabus with a Unit on â€Å"Appreciating Poetry† which was equally if not less exciting than the essay I had completed on Sherwood Anderson. The wizened and possibly wigged (or so the rumors went) Mrs. D saw to it that our first assignment in appreciating the art of poetry was that we were all to write poems of our own and once again embarrass ourselves in front of the class through recitation. Enter the predictable protagonal change. My poem was quite short and completely free verse, of course. But as I wrote it, I started to care how it sounded in my head and when I re... ...g, I probably would not have listened. This was most certainly something that I had to come to on my own. The only method to reach this plateau was writing on my own, and as much as I could. The key realization being that language was not some powerful structure that I could just tap into every now and again, but instead it was a set of signs that were in my complete control and jurisdiction to manipulate in a way that would reach readers, and more importantly myself, in an emotional way. The power lay not within the words, but in my ability to use them. In essence, these experiences with writing teachers did not affect me in and of themselves. The combined lessons on writing from all of my teachers, coupled with my own fascination with the power and effectiveness of words and language, brought me to the point I am at now: with writing as an integral part of my life.

Blockbuster Films Essay

Extra-terrestrial beings, intergalactic space flight, fictionalized re-telling of actual historical events, biological disasters that either threaten or bring human existence to a screeching halt, these are several of the most common elements and themes found in blockbuster films. But given the varying elements of blockbusters in film history, certain uncertainties give the term no exact definition. Yet, people, regardless if they are critics or ordinary viewers, are able to determine if a particular film is a blockbuster or not. Traditionally, blockbusters are regarded as films that denote popularity or success in production, but there is no authoritative body that gives requirements or criteria for judgement for films to be classified as blockbusters. Likewise, there exist no actual norms and standards on how films are to be classified as such. The fact that there uncertainty prevails over the true definition of a blockbuster leads to questions such as: is it based on towering budgets and high production values? Are blockbusters made through the popularity of the actors involved in the film? Or are blockbusters created and classified based on the brilliant, and seemingly flawless ideas spawned by a particular filmmaker’s imagination? In any event, Julian Stringers (2) introduction to the book, Movie Blockbusters, asserts that the term has an elusive nature because the meaning of the term blockbuster if used in the context of motion pictures is never fixed or clear. However, Stringer denotes that the term’s definition varies dependent of who speaks and what is being said (2). Stringer’s definition implies that a blockbuster does not necessarily have to have big budgets or sophisticated on-screen effects, rather, a complex spectacle that poses as a genre of the cinematic tradition. And by saying that a blockbuster is a genre, the distinct elements of the cinematic tradition categorize such films under blockbuster Take the case of Christopher Nolan’s 2008 blockbuster superhero film The Dark Knight. Apart from the concept of a masked vigilante using high-powered gadgets to ensure that no more 8-year old boy would lose his parents again, the idea of a rich, powerful, and influential individual sporting a caped suit and a mask to fight crime is can only be meant for children, or to some extent what the American culture came to call, the geeks.. Nevertheless, The Dark Knight managed to crawl its way to the hearts and minds of millions of movie goers. Set in a Gotham City manifesting itself as an archetypal city fired up by the sound of progress, but haunted by the vestiges of underground criminal activity, hypocrisy, and corruption, The Dark Knight revolves around Joker’s psychotic ploys to disgrace Gotham City’s law enforcement department while trying to reveal Batman’s alter-ego in the process. Putting Lieutenant James Gordon and District Attorney Harvey Dent in his primary hit list, Batman bends and distorts his principles in life to put a lid on the Joker’s irritating humour. As previously mentioned, the elements incorporated within a particular film create blockbusters. The Dark Knight is no exception as the actors and the film’s plot cooperate to venture the superhero genre to blockbuster. New York Times film critic Manohla Dargis describes Nolan’s The Dark Knight as a film that stands between the thin blurry lines of art and industry, as well as poetry and entertainment. This is because the dark portrayal of the characters in the film gives a totally new perspective on comic book characters in contexts beyond the limitations of comic strips. The Joker (Heath Ledger), for instance introduces the audience to what he calls a better class of criminal. The Joker is meant to become the irony of his own name that he exhibits a serious psychotic nature through gestures such as facial expressions and his walk (Nolan). Nolan’s Joker provides a justification for his criminal sanity by comparing himself to normal civilized individuals who feel that the laws being imposed make the world a safer and a better place. It is quite apparent in the Joker’s motives that he questions the morality of the corrupt law enforcement officers and politicians who allegedly feel that they are on the side of right. Heath Ledger’s performance as the Joker single-handedly carries the film to blockbuster status because of the dark, sadistic approach to the villain’s persona. Acclaimed film critic Roger Ebert of the Chicago Sun Times writes that Nolan’s Joker steps up in such a way that he puts up ingenious situations where Batman (Christian Bale), Police Lieutenant James Gordon, and District Attorney Harvey Dent (Aaron Eckheart) are placed in tight situations that challenges their morality in every sense. Dialogue is also one of the promising elements that place a particular film in the blockbuster genre. This is in large part brought about by language’s capability to leave an indelible mark to viewers from all walks of life. Adding more magnificence to the already unique, yet chilling gestures, the Joker’s lines exhibit a foreign implication that justifies his psychotic ploys. Simply put, how the Joker justifies the sadistic choices he gives to his adversaries establishes a different consciousness to people, especially ones who are oppressed by supremacists and bullies. In a similar magnitude, Eckheart’s iconic line â€Å"either you die a hero or you live long enough to see yourself become the villain (Nolan)†, tattoos a harsh reality that serves as a portrait of the current state of political. By literally and figuratively living to his words, Harvey Dent taps a reality, though morbid, reflects how power becomes self-destructive in such a way that it corrupts people who hold it. Apart from the remarkable performances, the film’s sinister and tragic plot spells out the word blockbuster. Primarily, Nolan’s The Dark Knight poetically departs from the typical good versus evil comic book plots. Nolan’s Dark Knight becomes darker as Gotham’s beloved citizen start to pile up for the caped crusader’s arrest, the Joker’s sick, demented mind takes advantage and prompts the infamous hero to come out and get him. Roger Ebert describes the plot as haunted that exceeds the boundaries of its comic book origins and transcends in to a shocking tale of tragedy. This is because most of the film’s scenes engages both the audience and the film’s protagonists to decide on moral dilemmas. In the end, no matter what choice the hero makes, a scar is left on his morale and his identity. Ebert adds that because of the actors’ ability to captivate the audience and because of how the film’s special effects respect the emotional acting, the audience are blindsided by the drama that pierces to their compassionate side. Through-the-roof funding and sophisticated production principles seem to pave the way for blockbuster films. But then again, how would a certain film become attractive and tasteful to the audience if it does not bring the promising elements in to consideration. Through its gloomy intensity and dark and horrifying humour, The Dark Knight managed to balance the weight production values with the term blockbuster. Likewise, the serious and cruel undertones of the film‘s plot not just redefines superhero movies but it clarifies what classifies as blockbuster as well. Works Cited Stringer, Julian.

Medieval Life Essay Example

Medieval Life Essay Example Medieval Life Essay Medieval Life Essay Essay on Medieval Life The Middle Ages was a period in Western European history that followed the collapse of the Roman Empire between the 4th and 5th centuries and lasted up into the 15th century.Medieval Europe was far from unified.It was a large area split into small, culturally diverse units that were never totally in control by any one authority.With the collapse of the Roman Empire, Christianity became the backbone of Western civilization.The papacy gradually gained secular authority and monastic communities, generally under the Rule of St. Benedict, flourished during this time period. By the 8th century, culture centered on Christianity had been established.Feudalism, with the manorial system as its backbone, became the typical social and political organization of Europe.The new framework gained stability from the 11th century, as the invaders became Christian and settled and as prosperity was created by agricultural innovations, increasing productivity, and population expansion.As Europe entered the period known as the High Middle Ages, the church became the widespread and unifying institution.Strong popes, especially Gregory VII, worked for a renewed Europe guided by a centralized church, a goal which evolved under Innocent III.The church was weakened by internal conflicts as well as by quarrels between church and state. Finally, the great medieval unity of Christianity was shattered by the religious theories that culminated in the Protestant Reformation.The transition from the Greco-Roman world to the medieval world was a sharp break from the ancient past which preceded it.More specifically, the church and state were never separate entities during ancient times.Also, in terms of economics, the economy that was created in Greece and Rome centered on agriculture saw little change during the transition into the Middle Ages.
