Narrative of the Life of Frederick Douglass Essay -- Papers

Narrative of the Life of Frederick Douglass Narrative of the Life of Frederick Douglass, depicts a vivid reality of the hardships endured by the African American culture in the period of slavery. One of the many things shown in Frederick's narrative is how slaves, in their own personal way, resisted their masters authority. Another is how slaves were able to create their own autonomous culture within the brutal system in which they were bound. There are many examples in the narrative where Frederick tries to show the resistance of the slaves. The resistors did not go unpunished though, they were punished to the severity of death. Fredrick tells of these instances with a startling sense of casualness, which seems rather odd when comprehending the content of them. He does this though, not out of desensitization, but to show that these were very commonplace things that happened all over the South at the time. One example that Frederick mentioned in the subject of resistance of the slaves against the masters is when he was under the charge of Mr. Gore. A slave by the name of Demby was getting whipped for a mistake he made. After Demby received but a few stripes he ran and jumped into a creek to the depth of his shoulders and refused to come out. This took great bravery considering Mr. Gore had a famous reputation for being nasty to slaves. Demby was given to the count of three to get out of the creek or he was to be shot, knowing the consequences Demby still refused to get out. He was then shot in the face by Mr. Gore with a musket. Demby truly resisted his master at the greatest cost he could have paid, his life. Another example given by Frederick in his narrative of how slaves were able to ... ...laves to be drunk during this time; in fact, they often got angry if they weren't drunk. Frederick feels that the master tries to make the slaves sick of freedom during this holiday time, by showing them only the abuse of it rather than the good. There was also a mention of a couple of "classes" among the black slaves. Slaves, from the viewpoint of Frederick, I feel, had a sort of "slave-class". The richer your master was the higher class you were, the poorer your master was the lower class you were. "To be a poor man's slave was a disgrace indeed!", was what Frederick mentioned of the issue. As you can see Frederick Douglass provided many glimpses into the world of slavery in his narrative. He showed many different examples of how slaves were able to resist their masters and create their own autonomous culture within the brutal system of slavery.

Describe and Compare the Two Forms of Cubism

According to the Tate Gallery’s exposition (1979) Cubism has remained the most important and influential movement of the 20th century, notwithstanding the movement’s short duration. According to Read (1994) the major period for Cubism was from 1907 to 1914, with Picasso and Braque as the main originators of the movement. The rationale for the Tate’s statement is given as â€Å"the artists associated with [Cubism] took some of the most decisive steps towards abstraction†, and this extreme development â€Å"has become the archetype of later revolutionary movements† (p. 84). The movement, according to Read, was the first abstract style of the 20th century, and named by the art critic Louis Vauxcelles, who took up a remark by Matisse about â€Å"Braque’s little cubes† (p. 100). One source (artlex. com) cites Vauxcelles as saying: â€Å"M. Braque scorns form and reduces everything, sites, figures and houses, to geometric schemas and cubes. † One of the most innovative developments is that the creators of Cubism sought to replace a single viewpoint and light source, normal within the western art world since the Renaissance, with a much more complete representation of any object, combining many ‘aspects’. Initially colours were temporarily abandoned and shapes were simplified and flattened. Space was furthermore rendered by means of oblique lines and overlapping forms (The Tate Gallery, 1979). According to Belton (2002, p. 109) Picasso and Braque both struggled with the problem of representing three dimensional objects and figures in the two dimensional medium of painting; â€Å"their solution was to create an abstract form that could display two or more sides of an object simultaneously†. Whilst Picasso’s Demoiselles d’Avignon is generally viewed as the first Cubist painting, Read (1994) argues that the painting might be more usefully viewed as ‘pre-Cubist’, or ‘proto-Cubist’, as it was so heavily influenced by Iberian or African art. Cezanne’s later work is often viewed as the catalyst for the development of Cubism, and Read cites Cezanne’s advice to Bernard â€Å"to deal with nature by means of the cylinder, the sphere and the cone† (p. 100). Cezanne, by trusting his eyes and attempting to express natural, binocular vision, allowed for the ‘truth’ of the shifted viewpoint (Moszynska, 1990). Cubism gives the artist a way of depicting the world in a way that goes beyond what can be seen, and attempts to deal with the energies of objects. According to Read (1994) Cubism could be categorized into various divisions, including ‘analytic’, ‘hermetic’ and ‘synthetic’. This essay will mainly concentrate in the analytic and synthetic forms of Cubism. The term ‘hermetic’ refers to the largely or wholly indecipherable way of representing an object in the flatter type of abstraction, as typical of both Braque’s and Picasso’s later way of working. In this phase the allover pattern became more important. Other sources (including artlex. com) refer to ‘analytic’ cubism as ‘facet’ cubism. Analytical and Synthetic Cubism acquired their names through the comments by art historian Einstein, and in effect are retrospective labels. Einstein wrote that the â€Å"simplistic distortions† employed by Picasso, as typified by his portrait of Gertrude Stein, led to â€Å"a period of analysis and fragmentation and finally to a period of synthesis† (as cited in Foster, Krauss, Bois and Buchloh, 2004, p. 106). The analytical phase of Cubism, as developed by Braque and Picasso, was characterised by a number of different features, starting with the contraction of the painters’ palettes, away from the full colour spectrum to rather monochrome selections, which Foster et al. term ‘abstemious’. The second characteristic is the extreme flattening of the visual space, â€Å"as though a roller had pressed all the volume out of the bodies† (ibid. , p. 106). The third characteristic identified by Foster et al. is the visual vocabulary used to describe â€Å"the physical remains of this explosive process† (p. 06). Foster et al. illustrate these features with Picasso’s portrait of Daniel-Henry Kahnweiler (1910) and Bracque’s painting The Portuguese (The Emigrant, 1911-12). The grey or tonal scale, the traditional tool of representing volume, is used very differently by the Cubists. Kahnweiler, the art dealer who exhibited both Braque and Picasso’s work, identified the â€Å"bringing about the unity of the pictorial object† as the exclusive concern of Cubism (Foster et al. , 2004, p. 107). Kahnweiler’s view as upheld by Greenberg, who saw Analytical Cubism as the fusion between two types of flatness: the â€Å"depicted flatness†, shoving the fragmented objects closer to the surface, and the â€Å"literal flatness† of that surface (ibid. , p. 109). Foster and his colleagues however question this: they note a number of differences between the evident intentions of Braque and Picasso in relation to the flat plane, with Picasso, being more ‘tactile’, more focused on exploring the possibilities of using Cubism for sculpture, and Braque more concerned with transparency. Steinberg too, urged against the blurring of Picasso and Braque’s pictures. The two exponents of Cubism saw themselves as being ‘roped together’ like mountaineers in their exploration of this new way of working, with the ebullient Spaniard referring to Braque as his ‘wife’. However, Braque was loyal to ‘passage’, the practice of visual slippage between adjacent elements, whereas Picasso, according to Foster et al. , had an â€Å"overwhelming concern with a vestigial kind of depth† (ibid, p. 109). Picasso seemed more focused on making depth tactile, as Foster et al. demonstrate with showing Picasso’s central plunging depth in Houses on the hill: Horta de Ebro (1909). They go on to argue that Braque is more concerned with the ‘diaphanous’ quality of Cubism, with the loss of traditional notions of figure and ground The Tate Gallery (1979, p. 85) presents Braque’s Clarinet and a Bottle of Rum on a Mantelpiece (1911) as a crucial point in Cubism, â€Å"when the breaking down of objects had been carried to a point very close to complete abstraction†. After this point Braque and Picasso started to introduce areas of wood-graining, the use of collage, and a re-introduction of colour, thereby representing objects in a more recognisable, but also more symbolic way. According to Gersh-Nesic (n. d. ) Synthetic Cubism integrates â€Å"high† and â€Å"low† art (art made by an artist combined with art made for commercial purposes, such as packaging), and according to some can be considered the first Pop Art. Even before 1912 Braque and Picasso had introduced stenciled lettering into their paintings. These stencils were not fine art, they were used for packaging and pub signs. The stencils draw attention to the surface of the canvas, since the uniform letters appear independent of what's painted underneath them. Two technical innovations exemplify new development in Cubism: papier colle and collage. Papier colle involves sticking coloured paper onto the canvas and was invented by Braque. Collage was developed by Picasso, and involved sticking all sorts of materials, such as leather, newspaper, material and rope, onto the surface. Sticking different materials, such as woodgrain, onto the surface of the painting playfully confused what was real and what was an illusion (Tate, n. d. ). New, provocative questions are raised with the use of collage, namely: what is more realistic, to perfectly simulate the look of a newspaper in oil paint, or to stick actual newspaper onto the canvas? (Tate, n. d. ). Wadley (1970, p. 13) holds that â€Å"technically and conceptually† Synthetic Cubism was â€Å"a denial of the European tradition†, in that the surface was now the furthest point from the spectator, not the nearest. Artists working in a synthetic way started with the terms of painting, and from them composed an image which they could justly claim was more real, â€Å"since it in no sense distorted or imitated something else† (ibid. p. 14). Gris, who was the clearest formulator of cubist theory, stated: I work with the elements of the intellect, with the imagination. I try to make concrete that which is abstract. I proceed from the general to the particular, by which I mean that I start with an abstraction in order to arrive at a true fact. Mine is an art of synthesis, of deduction. (ibid. , p. 129) Gris was called a ‘demon of logic’ by Apollinaire. Indeed, his way of working and thinking was different from his Cubist colleagues. According to Wadley the integration in Gris’ work is tighter than in comparable Picassos or Braques. Gris used collage only in his paintings, and its effect is always to strengthen the rigid division of the surface. [ ]There is no hint of Picasso’s ragged edges and random encounters, nor of Braque’s simple elements floating in a spacious arena. The total effect is of tight concentration. (Wadley, 1970, p. 82) Gris’ meticulous style is evident in how he has painstakingly arranged the letters in ‘Le Matin’ in Man in the Cafe, to correspond with the diagonal columns and echo the horizontal line elow (ibid). Foster et al. (2004) make a ‘semiotic’ reading of Picasso’s use of material in his Violin (1912): the ‘twin’ pieces of newsprint paper represent on the one hand the frontal, opaque (wood of the violin), as well as the transparent, amorphous ‘ground’ (background colour). They go on to claim that a similar visual play of meaning is evident in Picasso’s Bottle of Vieux Marc, Glass and Newspaper (1913), where a piece of wallpaper is used to represent the liquid in the glass, the rim of the glass, and the ground of the table-cloth. The cut out piece used for the liquid (looking like a chef’s top hat) represents transparency, whilst the ‘negative shape’ left by the incision represents the solid stem of the glass. The viewer might be left with the question whether the ever playful Picasso was just enjoying a visual pun, or whether he intended any of this to be read as ‘signs’. The artist himself stated: â€Å"Mathematics, trigonometry, chemistry, psycho-analysis, music and whatnot, have been related to cubism to give it an easier interpretation. All this has been pure literature, not to say nonsense, which brought bad results, blinding people with theories. (Wadley, 1970, p. 128) During its lifetime both Analytical and Synthetic Cubism encompassed and influenced many artists – the most notable of these being Leger, the three Duchamp/Villon brothers, Robert and Sonia Delaunay, Gleizes and Metzinger (who published a book on Cubism). For some of these artists Cubism functioned as a transition, although Picasso would hold that â€Å"Cubism is neither a seed, nor a foetus, but an art dealing primarily with forms, and when a form is realized it is there to live its own life† (Wadley, p. 28). It led artists like Piet Mondrian to what he saw as its logical end, complete abstraction. Cubism may have been short-lived as a movement, but it continues to influence contemporary art to this day. Collage, for instance, has become a widely practiced form of art. And in terms of form, the practice of reducing everything to the ‘cylinder, the sphere and the cone’ was brought to mind on viewing some of Manolo Valdes’ work, in an exhibition in The Hague this summer.

Web. 20 Jan. 2013. This paragraph is a run though of the timeline events. Going all the way back to 3000 B. C. the first Hypocaust was born. Ancient Romans had invented the hypocaust. The hypocaust is an under floor heating system that is a chamber that collects heat and leaves it under there. Going up to 2500 B. C. the first fixed central hearths were first excavated in Greece. In 1300 B. C. King Arzawa had an under floor heatin g system installed into his palace in Turkey. Later in 80 B. C. Sergius Orata started to create designs for heating systems and brought technology to the Romans. Crude fireplaces were made around 800 A. D. and were later widely spread throughout Europe in the 1300’s. The chimney was invented around the 1400’s. They were large in diameter so that the Chimney Sweepers could fit up into them to clean them out. 100 years later in 1500, masonry stoves became the â€Å"new thing† to have.They also became very common. Louis Savot invented the raise gate system and designed a circulating fireplace. In early 1600’s, the first standing stove, or not connected to a wall or mounted to anything, was the Furnus Acapnos, or the smokeless stove, invented by Dalsme. He also introduced fresh fuel in the same opening as combustion air, directing all combustion products over already-burning fuel, a design that ensured complete combustion. The iron box stove, the earliest sto ve to be introduced into North America, was invented by Dr. John Clarke.William cook was the first to propose the way of using steam to heat up rooms, in 1745. In the late 1700’s, M Bonne invented an actual hot water heating system instead of William Cook’s steam heating system. In 1805, William Strutt invented a warm air furnace that had a riveted, wrought iron air chamber encased with bricks. This chamber had ducts that fed into rooms and blew heated air into the rooms. The way this chamber was built was to keep the hot air from escaping from the chamber and having heat loss. They were referred to as cockle, belper, or derby stoves.Isaac Orr invented the airtight stove so there would be no heat loss inside the chamber in 1836. Professor Warren Johnson taught at a school in Wisconsin, where the only means of room temperature control was to tell the janitor to go to the basement and adjust steam valves. Johnson developed an electric annunciator system in 1873 that was used to signal the janitor when heat needed adjusting. He continued experimenting and in 1885, patented a thermostat that relied on compressed air to operate steam valves. He then established the Johnson Electric Service Co. to manufacture and install his system.Johnson went on to invent the humidistat for control of the humidity in buildings in 1905. In 1905-1908, Milton Fessler invented a residential oil burner so that residents could have their own house heated easily without stoking coal in a fireplace every hour. Coal-less Mondays were introduced in 1917 to save coal and stimulate the use for oil and gas since there wasn’t much coal around or to be found regularly. In 1926, the Electric Refrigeration News began to publish that heating had advanced from the campfire in a cave, to something so silent, so unnoticeable.And in present day, thermostat controls air and ducts are fed in a way we can’t see the m and as well as fed to each room through a vent in which air i s blown out of. We take advantage of just â€Å"turning on the heat† every day that we don’t even bother to thing what had to happen way back when to heat thing up. The way of heating has been a system that not everyone thinks about. It has gone from the campfire, to the hypocaust, to stoves, to compressed valves, to thermostats, to an automatic heating with the push of a button. Over time, the way of heating has improved and impressed many along the way.It used to be having a chimney and stoking coals for five minutes ever hour just to keep the coals burning and hot and giving off heat. To progress this way of heating, there cannot be only one inventor. There are many who have created accessories, or major parts to different systems. The inventors go from ancient Roman empires and ancient Greek empires to people we have never heard of, but have improved life as we know it tremendously. This is the way of heating. Going into B. C. years, there were some unknown dates a nd some known dates. First was campfire.We all have heard off the story where cavemen are in a stark cold cave with a campfire. That’s just an obvious fact. Later on the hypocaust was made my ancient Romans and ancient Greeks. The word hypocaust refers to a subfloor radiant heating system: suspended floor with space for gases and hot smoke. The word hypocaust comes from the Latin  word Hypocaustum  which originally meant a ‘burning underneath'. Hypocausts were very important to Roman’s system of heating. The hypocaust heated baths and large rooms. Along with the hypocaust, there were sometimes hollow walls in ancient structures.These hollow walls would help maintain even temperatures as well as eliminate condensation. The small pillars of stacked bricks would have supported a fireproof floor that was heated by means of air circulation in the under floor chamber with an external furnace as heat source. The art and science of the hypocaust systems was lost afte r the fall of the Roman Empire. Western heating science had advanced very little in the period of the Dark Ages. Around 2500B. C fixed central hearths were excavated in Greece. In 80 B. C. Sergius Orata brought high art designs to Roman technology.At first Romans were only heating up their floors, but later used heated walls and some were designed as early as warm air heating systems. By this, introducing heated air through floor openings. This is the end of the B. C. heating ways. Now going into the A. D. times, from 1600-1800 specifically. In the late 1600’s, Dalsme invented the first freestanding stove, not mounted to a wall, called the Furnus Acapnos to the smokeless stove. He also introduced fresh fuel in the same combustion air directing all products over already burning fuel, a design that ensured itself. The smokeless stove was a great advance but, it was accepted slowly.The earliest stove introduced into North America was the cast iron box stove which was invented by Dr. John Clarke in 1652. This kind of stove was originally made in Holland and later imported into England after1600. Louis Savot invented a raised gate system and designed a circulating fireplace. He used a hollow iron bottom and back in a hearth, at which cold air entered the bottom, was warmed, and entered the room through openings, in early 1600’s. In 1653, Sir Hugh Platt proposed using hot water to dry gun powder and Sir Martin Triewald proposed warming greenhouses with hot water.This might be referred to as the hydronic system, which is the heating of an object by water. In 1735, John Desaguiliers designed the first modern heating blower which was turned by hand by an operator referred to as the ventilator for the British Houses of Parliament. The design of centrifugal, acting from or away from the center, blowers was continually improved in England and Europe during 18-19 century. The early fans were mostly operated by steam engines. In the late 1700’s, M. Bonn e in France constructed an actual hot water heating system using a boiler.The French idea was introduced into England by the Marquis de Chabannes later in 1816. By the 1790’s, the steam heating way had only progressed in England, being used to heat mills and factories. The advantage of steam heating is the avoidance of the expense of insurance. This is the end of the 16th and 17th century. Moving ahead to the 18th and 19th century, there were many important events, inventions, and inventors. In England at about 1805, William Strutt had invented at warm air furnace that included a riveted wrought iron air chamber that is encased with bricks.The design had a couple inches of space between the brick and iron chamber allows air to circulate. A large space on the outside is split horizontally on two sections, the lower for cool air and the upper for heated air. Cool air moves from the lower chamber through the openings and moved out through the upper openings into the heated air c hamber. As well as ducts were fed into rooms in which heated air is blown out of them. His hot air furnaces were referred to as cockle, belper, or derby stoves.December of 1815, Marquis de Chabannes obtained a patent for a method of conducting air, and regulating the temperatures in houses or buildings. Hot air systems were introduced in the U. S. before 1820. The fist building to be centrally heated was the Massachusetts Medical College in 1816. In 1831, Angier Perkins realized the drawbacks of bulky heating systems. So he designed a high pressure hot water system using a small diameter, thick walled wrought iron pipe that he patented. His system heated water in pipe coils placed in a furnace, then circulated hot water to coils of pipe in the rooms to be heated.In 1833, Eliphalet Knott invented the base burners for stoves, and in 1836, Isaac Orr invented the air tight stove so that there would be no heat loss. Joseph Nason and James Walworth introduced the Perkins method of high pr essure hot water heating system in the U. S†¦ But in that same year of 1842, the method was not used. The use of hot water systems had been limited till 1880’s when that had surprisingly become popular. Steam heating for residents had rapidly declined and hot water became the dominant method especially in the eastern part of the United States.Joseph and James installed steam systems afterward, using small diameter wrought iron pipes. They installed numerous amounts of steam systems in large buildings, including the White House and the Capitol building. In 1846, James and Nason installed the first fan type system for the United States Customs House in Boston. Later in 1849, F. P. Oliver had invented a stove with thermostatic draft control. By 1851, catalogs started to list cast iron registers, which are often 12-by-24-inch grills covering a large air-intake tube. Outflow vents vary in size depending on the room.A common size is 10 by 12 inches for most living spaces, avai lable in black, white, finished, gold, bronze, or just with nickel plating. They would package them with straw in a wooden crate. Packing was expensive. Stephen Gold was a Connecticut stove maker who began experimenting. The steam heating systems seemed too complicated and unsafe, but furnaces had seemed completely uncomplicated and very safe. Many people were uncomfortable in building heated by air because they had seamed scorched. Gold had overcome these issues and was granted a patent for improvement in warming houses by steam.Gold’s system was unique at the time. Large steam systems used coils or rows of pipe to heat rooms, while Gold used the first radiator, a device consisting of two dimpled iron sheets that were riveted together at dimples. The edges were rolled over with a piece of cord as a gasket, which is a rubber seal. Gold’s radiator came to be called â€Å"the mattress radiator† due to the way it looked, in 1854. In the same year, Gold invented a b oiler which was made of wrought iron and included a draft regulator along with a water valve.This system was later manufactured by Connecticut Steam Heating Company. Radiators date to 1863. Joseph Nason and a new face of Robert Briggs patented a new design including vertical wrought iron tubes screwed into a cast iron base. The golden age for warm air furnaces was after the Civil War. In 1869 a shoemaker by the name of Benjamin F. Sturtevant patented a combination fan and heat exchanger for two purposes: 1) for cooling 2) for heating. He established a company to manufacture and sell fans and heating systems. Here is a story that took place in 1873.Professor Warren Johnson taught at a school in Wisconsin where the only way to change the temperature was to run down to the janitor and have him turn the valves of air to change it to either warm or cool. Johnson developed an electric annunciator, which is electronic signaling device, system that was used to signal the janitor when heatin g need to be adjusted. In 1885, he created and patented a thermostat that relied on compressed air to operate the valves. He later established the Johnson Electric Service Company to manufacture and in install his systems. By 1874, Nelson Bundy invented the most popular cast iron radiator.In 1886, Albert Butz patented a thermostat that controlled damp drafts. The thermostat was electric, using battery to activate a spring loaded motor. In the 1890’s, the heating systems were quite sophisticated. Some included thermostatic and zone control, which is a forced air system. All of the early inventions of forced air systems had concerned themselves with large buildings. These combinations of the 1890’s of a fan and a heater were referred to as the plenum or the hot blast systems. In 1895, Charles Foster patented a damper type register. In 1899, Novelty Manufacturing Company was the first to make the steel register.The most successful hot blast system was the Vento sectional cast iron surface invented by John Spear in 1903, which was manufactured by American Radiator Company. Professor Warren Johnson went to invent the humidistat to control the humidity of a home in 1905. In that same year, manufacturers were frightened and formed the Federal Furnace League to elevate warm air heating to the rightfully deserved position. In 1905-1908, Milton Fessler invented a residential oil burner so that residents could have their own house heated easily without stoking coal in a fireplace every hour.During 1912, residents and homeowners had to wake up early to stoke the coal in the fire and replace the coal with fresh coal. Guesswork and experience helped tell how much coal to use. The first electric coal stoker that was controlled by a thermostat was invented in 1912, and by 1920 electric coal stokers could be found by anyone. During WWI, there was a coal shortage and the government had to find a way to conserve energy gave a slight nudge to the automatic systems. Lawrence Soule improved his idea of Aerofin heating surfaces. This Aerofin idea used spirally wrapped copper sheets to produce a light weight eat exchanger, during the 1920’s. After WWI, Butz Thermoelectric Regulator Company had pushed the idea of oil burner controls and had met with the Honeywell Heating Specialties in 1927 to form the Minneapolis Honeywell Regulator Company, or know to us today as Honeywell Incorporated. The heating systems of the 19th century operated with a low pressure, only using one to two pipes and a boiler or steam engine for the steam source. This is pretty much the last of the 18th-19th century events and inventions. This last paragraph explains the inventions and events in the 20th century.There are four main different types of modern central heating, consisting of gas and oil burners, solid fuel central heating, radiators, and electric heating. Gas and oil burners can be chimneys because they use gas to and oil to burn the wood to make a fire, wh ich warms up the room. Solid fuel central heating systems provide hot water, warm water, or any kind of heated liquid. Radiators  are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. They distribute the heat by natural air circulation.The process of electric heating involves electrical energy being converted to heat through an electrical appliance. Other ways to heat homes are wood stoves, forced air systems, and by radiant heat. We also use thermostats that just â€Å"change† the temperature of rooms by the push of a button, that we often just take advantage of it. Houses often had ducts that come from a furnace that go to each room and blow air when you change the temperature on the thermostat. Some houses have a large panel of widows instead of a wall and the suns radiation waves go through the window and transfer into radiant heat to warm out the house.Another system houses have is called the forced air s ystem. Air is pushed by fans into a furnace and when it comes out, there are more fans after the furnace to push the air down the ducts and into the vents which lead into the room. This leads up to the year of 2013. So as it’s obvious, central heating has come a long way and improved much over the years. Many are impressed by this complicated technology and impressed by the intricate designs and inventions over the years. As spoiled people with high expectations of high quality technology, we have taken advantage of the heating systems.We just â€Å"turn on the heat† or â€Å"turn on the AC† and not even thinking about what has had to happen for this technology to come up to where it is. Heating is very important because without it we would not exist. We would freeze to death, literally. We owe a lot of thanks to all the inventors way back then who made this invention a lifestyle and a luxury. Heating has advanced so tremendously, from the campfire in a cave to something so silent so unnoticeable in life, from the hypocausts to the furnace, from the freestanding stoves to the chimneys.When we use heat or use a thermostat, we don’t tend to think about how heat has progressed. We think about the necessity of warmth, and how we are going to â€Å"freeze to death. † This paper and research has made me more aware of what happened for society to get heat, and has made me appreciate what I have. Fifty-four percent of the energy used in the average home is for heating and cooling rooms, and there are 114,199,622 households in the US as of the 2010 census. That’s a lot of energy used! The most simplistic way to put it is that we take advantage of things we have every day. I am thankful for heat, are you?

Text Organization Guide for English Learners

Text Organization Guide for English Learners Text organization refers to how a text is organized to help readers follow and understand the information presented. There are a number of standard forms that help text organization when writing. This text organization guide will help you logically guide your readers through your text. Text Organization: Referring to Ideas Already Presented Pronouns and determiners are used to refer to ideas, points or opinions that you have previously introduced, or will immediately introduce. Here is a quick review of pronouns and determiners with examples. Pronouns Remember that ideas, opinions, and arguments are considered objects in English which take object pronouns. it / it / its - singularthey / them / their - plural Examples: Its importance can not be underestimated.It now becomes clear that their role in production is vital.The government has given it ample consideration but rejected its validity. Determiners this / that - singularthese / those - plural This is key: Children need to be encouraged in order to succeed.Jefferson referred to those as unnecessary complications. Make sure that pronouns and determiners are clearly defined either before, or immediately after their introduction in order to avoid confusion. Examples: The need for economic growth is vital to any society. Without it, societies become defensive and ... (it refers to need for economic growth)These are vital for any job: interest, skills, manners... (these refers to interest, skills, manners) Text Organization: Providing Additional Information A number of forms are used to provide additional information in text organization. These forms are used at the beginning of a sentence to link text to the previous sentence: In addition to X, ...As well as X, ... Examples: In addition to these resources, we will require a further investment of ...As well as his difficulties in childhood, his continuing poverty as a young adult caused many problems. These phrases can be used in the middle of a sentence or a phrase to provide additional information in your text organization: alsoas well as Examples: Our commitment to the cause, as well as our financial resources, will make this possible.There was also time considerations to take into account. Sentence Structure: Not only...but also The sentence structure Not only clause, but also clause is also used to provide additional information and emphasize the later point in your argument: Examples: Not only does he bring experience and expertise to the company, but he also has an outstanding reputation.Not only are the students improving scores, but they are also having more fun. NOTE: Remember that sentences beginning with Not only ... use inverted structure (Not only do they do...) Text Organization: Introducing a Number of Points Its common to use phrases to signify the fact that you will be making different points in your text. The simplest way to indicate that you will be touching on a number of different points is to use sequencers. The appearance of sequencers indicates that there are points to follow or that precede your sentence. For more information on sequencers, continue on to the section on sequencing your ideas for text organization. There are also some set phrases that point to the fact that there are a number of points to follow. Here are the most common: There are a number of ways / means / manners ...The first point to make is ...Lets begin with the assumption that / the idea that / the fact that ... Examples: There are a number of ways we can approach this problem. First, ...Lets begin with the assumption that all of our courses are necessary for our students. Other phrases are used to indicate that one phrase is related to another in an additional sense. These phrases are common in text organization: For one thing ...and another thing / and for another ...besides that ...and besides Examples: For one thing he doesnt even believe what hes saying...., and another thing is that our resources cant begin to meet the demand. Text Organization: Contrasting Information There are a number of ways to contrast information in text organization. In most cases, two clauses are used: one with the most important information, as well as a clause introduced with a word or phrase showing contrast. The most common of these are although, though, even though, but, yet and despite, in spite of. Although, Even Though, Though Notice how though, even though or although show a situation which is contrary to the main clause to express conflicting information. Even though, though and although are synonymous. Use a comma after beginning a sentence with although, even though, though. No comma is required if you finish the sentence with although, even though, though. Examples: Even though it was expensive, he bought the car.Though he loves doughnuts, he has given them up for his diet.Although his course was difficult, he passed with the highest marks. Whereas, While Whereas and while show clauses in direct opposition to each other. Notice that you should always use a comma with whereas and while. Examples: Whereas you have lots of time to do your homework, I have very little time indeed.Mary is rich, while I am poor. Whereas, While But and yet provide contrary information that is often unexpected. Notice that you should always use a comma with but and yet. Examples: He spends a lot of time on his computer, yet his grades are very high.The research pointed to a specific cause, but the results painted a very different picture. Text Organization: Showing Logical Connections and Relations Logical consequences and results are shown by beginning sentences with linking language indicating a connection to the previous sentence (or sentences). The most common of these include as a result, accordingly, thus, hence, consequently. Examples: As a result, all funding will be suspended until further review.Consequently, the most important elements combine to provide a rich tapestry effect. Text Organization: Sequencing Your Ideas In order to help your audience understand, you need to link ideas together in your text organization. One of the most important ways to link ideas is to sequence them. Sequencing refers to the order in which events happened. These are some of the most common ways to sequence in writing: Beginning: Firstly,First of all,To start off with,Initially, Examples: Firstly, I began my education in London.First of all, I opened the cupboard.To start off with, we decided our destination was New York.Initially, I thought it was a bad idea, ... Continuing: Then,After that,Next,As soon as / When full clause,... but thenImmediately, Examples: Then, I started to get worried.After that, we knew that there would be no problem!Next, we decided on our strategy.As soon as we arrived, we unpacked our bags.We were sure everything was ready, but then we discovered some unexpected problems.Immediately, I telephoned my friend Tom. Interruptions / New Elements to the Story: Suddenly,Unexpectedly, Examples: Suddenly, a child burst into the room with a note for Ms. Smith.Unexpectedly, the people in the room didnt agree with the mayor. Events Occurring at the Same Time While / As full clauseDuring noun (noun clause) Examples: While we were getting ready for the trip, Jennifer was making the reservations at the travel agents.During the meeting, Jack came over and asked me a few questions. Ending: Finally,In the end,Eventually,Lastly, Examples: Finally, I flew to London for my meeting with Jack.In the end, he decided to postpone the project.Eventually, we became tired and returned home.Lastly, we felt we had had enough and went home.

Caligula essays

Caligula essays Caligula has been known to history as a colorful emperor. He is the youngest son of Germanicus Ceaser and the grandnephew of Tiberius. Caligula as a child was said to have been very ill with a high fever that probably affected his mind. That would explain all the strange things that he did throughout his life. Gaius was given the name Caligula (Latin for little boot) in the military camps where he spent some of his early life. He succeeded his granduncle Tiberius in the year 37. Caligula was very popular with the army at first since he had served himself. Unlike Tiberius, Caligula was not concerned with having a surplus in the Roman treasury. Soon after he came to power, he began to throw lavish festivals and gladiator games. The people of Rome knew that he was depleting the treasury, and quickly became unpopular. He soon answered them with acts of tyranny and began to have people executed at whim. He banished or murdered most of his own relatives. Caligula committed incest with two of his three sisters. His retreat is to Capri where he indulges himself in immoral acts In 37, Caligula becomes ill, and tells all that he is not really ill, but is metamorphasizing into a god. He then forces the Senate to deify himself and his three sisters. He also forces the Sensate to make his horse a Senator on the grounds that it is Alexander The Greats horse reincarnated. This all becomes too much for the people of Rome. The leader of the Praetorian Guard leads a revolt and Caligula is assassinated on January 24, 41. ...

3D Printing for the Built Environment-Free-Samples for Students

3D printing is the process of manufacturing an object in three dimension formations with material layer by layer. 3D printing is one of the additive layer fabrication processes, this technology uses a computer-based system to make a 3D model of the object and manufacture it by adding a layer at a time. This technology has enhanced and significantly upgraded into a great instrument for various fields. Merging various fields in single product formed 3D printer as it involves design, electronics, manufacturing, materials and business. 3D printing is known as additive manufacturing, as it is not like subtractive manufacturing and it adds material with lot of layers instead of removing material (Hager, Golonka and Putanowicz, 2016). This is beneficial for many fields such as researchers, manufacturers, designers, engineers and scientists. The 3D printing technology is revolutionising the procedure of manufacturing in various industries. It entirely modifies not only the manufacturing fiel d, but also entire life of people in the future as 3D printer makes feasible to complete model in a single process. 3D printing is an advancement of printing technologies which can manufacture or reproduce elegant structures in one piece. This technology offers direct manufacturing as through a printer, physical product can be generated directly by inputting a design from an idea. 3D printing is an innovative technology, it started in the 80’s and named as â€Å"rapid prototyping†. Today, 3D printers offer to manufacture a physical object from digital model as per the imagination. In order to use 3D printer, firstly preparation is mandatory before printing, like designing a 3D file of the object that has to be printed. To design 3D model or file there are many ways such as through CAD software, websites like Blender and Google SketchUp or it can be simply downloaded from online marketplace for pre made designed models (Kellens, et. al., 2017). When the 3D model is ready for printing then the printing process has to be done. For printing process, initially material has to be decided which would be required for the object. 3D printing provides vast variety of materials such as plastics, resins, sand, ceramics, metals, textiles, biomaterials, glass, food and also lunar dust (Peng, 2016). After deciding the materials for manufacturing and finishing of the object for the accurate result of design, the object has to be printed and if it has not been sanded, lacquered or painted to finish it as deliberated then usually it cannot be directly used or delivered. Printin g methods depend on material selected for the project. Printing techniques of each material are described; if plastic or alumide has to be used during manufacturing then fused deposition modelling technology (FDM) and SLS technology would be best suitable. FDM is the most frequently used printing technique because of the number of printers accessible in the market. In this technique the material is being melted and emitted with the help of a nozzle by each layer at a time to 3D print the object. Thickness of the layer is influenced by the quality of 3D print (Sculpteo, 2018). As compared to other 3D printing technologies, FDM is an affordable 3D printing process. SLS technology is a laser sintering 3D printing technique which includes fabrication of an item by melting layers of powder collectively to manufacture an object. If the materials are resin or wax during the additive manufacturing then there are four methods of 3D printing such as Stereo lithography (SLA), Digital light processing (DLP), Continuous liquid interface production (CLIP) and Multi jet printers. A tank is used of remediable photopolymer resin in SLA method. The build plate goes down and where UV laser creates cross section layer by layer then the liquid polymer is exposed to light. DLP method is similar as the SLA method, the difference is that in DLP method a safelight is used instead of UV laser to cure the photopolymer resin (Sculpteo, 2018). DLP method can be used for silver and brass 3D printing. CLIP method is used with a continuous sequence of UV images which are produced by a digital light projector, with the help of an oxygen permeable, UV transparent window under a liquid resin bath. Multi Jet printers are similar to SLA method, in this method UV light is used by poly jet and multi jet 3D printing techniques to link a phot opolymer. A printer jet pours tiny droplets of the photopolymer in the shape of the first layer and not scan laser to cure layers. When metal has to be used as material, then the methods would be DLP, Direct metal laser sintering (DMLS) and Electron beam melting (EBM). DLP can be used for silver and brass 3D prints. Primarily a wax model is 3D printed then lost was casting technique is used as before the wax is melted the pattern has to be made around it to create the object. In DMLS method laser is used as primary source to sinter metal powder through laser cross section layer by layer of the object (Sculpteo, 2018). In EBM method laser is not used during 3D print, instead of laser and electron beam is used to 3D print the metal. This electron beam melts the metal powder layer by layer and has ability of full melting of the metal powder. When multicolour is required during the 3D printing, then the methods used are Binder jetting, Selective deposition lamination (SDL) and Triple jetting technology (Poly jet). Binder jetting is very popular and useful as it provides the facility of producing detailed 3D prints with colour. To apply a layer of powder on the build platform, the automated roller is used. Liquid binder and colour can also be applied to create a cross section of the product. SDL method is processed with the help of paper. In this process layers of adhesive coated paper are stuck together with the support of high temperature roller and then slash with a laser cutter to give the appropriate shape (Fosso, 2017). Triple jetting technology includes printing with the three materials and can also use three colours. 3D printing is experiencing a boom in recent years. This technology is also known as additive manufacturer and helps to design and manufacture products faster than ever before. Hence, it is becoming more potential even if we consider environmental issues. 3D printing is friendly for environment by supportable material. If we think about sustainability then the important part is material used for 3D printing (Chen, 2016). In the last years, there have been some cases where development of 3D printer materials from recycled plastic has been practiced. According to Joshua Pear the plastic fibre from milk jugs is energy efficient. 3D printing is turning waste into fashion as this technology is not only helpful in reducing waste. Whereas, it also offers variety of ways for reuse the waste for the fashion industry. For example, the sports brand Adidas has printed shoe, which has a 3D printed midsole manufactured from recycled fishing nets. 3D printing uses a lot of energy. 3D printers are utilizing lasers or heat 50 to 100 times more electricity than production from traditional techniques to manufacture the same object of the equal weight. However, it has important impact on environment as in many areas electricity has been generated from fossil fuel sources (Liu, et. al., 2016). Less material is being used in 3D printing technology as compared to traditional manufacturing methods. 3D printing methods offers to melt, fuse, bind and sinter the amount of plastic, metal and ceramic. Whereas, in subtractive manufacturing usually cutting has to be done of excess material so the additive manufacturing is very different from the subtractive manufacturing. As energy has not been used to produce extra material and also to remove it during subtractive method has to be done. Hence, it uses less energy as compared to other methods. 3D printing is beneficial for environment as it has the ability to print objects at any place like at store or at home and this reduces the need to transport the objects manufactured. Hence, helpful in lowering the emissions caused with the transportation. 3D printed products are usually up to 50 per cent lighter than the products manufactured through standard techniques (Pirjan and Petrosanu, 2013). Hence, during transportation of the 3D printed products, less energy would be required. Whereas, the transportation is very less of the overall environmental impacts because when a product has to be shipped from thousands of miles away in any other country. 3D printed objects are usually manufactured of thermoplastic, which is not the greenest material and cannot be frequently recycled. Thermoplastic can be recycled by several machines in the market like the material which is from unsuccessful prototypes for use in 3D printers (Mendoza, 2015). Whereas, the more this recycled plastic is being recycled it becomes more delicate which tend users to become reluctant to try it. The industry is trying and working on improving their recycling technologies. 3D printing is environmentally-friendly as it prevents to use traditional petroleum based materials and includes the use biodegradable and renewable plant based sources. The two major plastics used in additive manufacturing come from corn (Rogers, et. al., 2016). Poly lactic acid creates little waste as it is biodegradable, renewable and nontoxic. In this industry because of these reasons this choice is on priority. This industry asks their designers to make lighter weight products. More time would be consumed for making something big. So, they line up the incentive structures of the economies and this would be helpful in meeting environmental priorities. 3D printing offers to manufacture the light weight and strong complex shapes very fast. This technique helps in manufacturing cars and wind turbines and when these products are made with lighter weight parts then they can be helpful in saving energy. 3D printing also has positive impact socially than environmental (Silva Barros, 2017). As 3D printing can be used at any place for printing objects, then this technique should be used in developing countries that are not connected from global supply chains. Additive manufacturing can efficiently employ raw materials and their functionality. In a powder based process, nonconsolidated raw materials are used such as in powder bed fusion that can be reused that would help in diminishing material waste (Boon and Van, 2017). Optimisation in the design of the object has been enabled by free form fabrication of the additive manufacturing. The optimal design will help in reduction of materials, energy, fuel, or natural resources in the product manufacturing.   When huge amounts of energy are wasted like in moulding or casting, then the additive manufacturing can change the process and can also save resources utilised on the fabrication of tooling during production. 3D printing is revolutionizing every field. This technique is beneficial for environment in many ways such as, new body parts can be printed and working ovaries for mice can be created. Biologists made infertile mice fertile again by providing them 3D printed ovaries. Hence, it can be said that this technique is helpful in saving the world (Mohr and Khan, 2015). This technique is helpful in predicting natural disasters as 3D geospatial modelling is easy to create, carry and transfer environmental safety messages, 3D landscapes has been best way of communication for geoscientists by satellites designed for disaster response. With the help of 3D printing, scientists can provide an understanding to people regarding landscape and the risk (Insight, 2013). This help in taking prior and effective actions for safety. All over the globe these printed models are being used for the safety purpose, these address critical problems such as cliff erosion, volcanic eruption and wildfires. 3D printi ng technique offers to create a bamboo bike by using natural resources like hemp and resin (Baumann and Roller, 2017). This bike has been created by using sustainably sourced material, holding bamboo rods together by tubular joining pieces called lugs. Lugs have been created by bio fibre and a plant based resin glue. When bamboo bicycle is created by using 3D printing then it has been analysed that lugs have been created from carbon fibre filament, carbon fibre is recyclable.      3D printing can be done on demand, as parts can be manufactured when they are required by producing on demand. This simply means instead of manufacturing products in bulk, now with the help of 3D printing production can be done when the objects are needed. This is beneficial in saving storage (Surange and Gharat, 2016). The less manufacturing of stock allows putting the less capital, on demand production is also beneficial because risk of unsold stock or wastage stock is less and also prevent from selling the stock on discount (Garcia, Claver and Sebastian, 2017). 3D printing lower the carbon dioxide footprint, other manufacturing techniques causes the emission of carbon dioxide because most of the machines use fuel for their operation. The carbon dioxide causes air pollution and global warming. According to the research done by an aerospace and defence research organisation on the environmental impacts of additive printing, it was found that along with the fact that this technique s ave usage of energy and reduce the carbon dioxide emission during transportation, 3D printing also makes lighter aircraft components, almost 40% less carbon dioxide has been used during the production process of these kind of printed parts. It has been concluded from the above report that 3D printing technology has positive impact on the environment. 3D printing is also known as additive manufacturing and we have discussed the process of using 3D printing and also discussed about the materials used in this technique. There are different methods of 3D printing according to various materials. We have discussed the advantages and limitations of this technique. 3D printing is having a tremendous impact on industries such as aerospace and automotive to healthcare. This technique is turning waste into fashion, as it is utilizing waste in fashion industry. Huge amount of electricity and energy is being saved in this technique as compared to other techniques. 3D printing prevents the carbon dioxide emission. It is beneficial for environment as it prevents to use petroleum based materials and tends to use biodegradable and renewable sources. With the help of 3D printing technique the transportation has been reduced as it can be used anywhere and this technique offers to manufacture lighter weight products. This technique helps in knowing the disasters previously so that prior safety actions could be taken. 3D printing is an additive manufacturing which is beneficial for environment.

Literature Research Paper Example | Topics and Well Written Essays - 500 words

Literature - Research Paper Example He suggests that Allende is plagiarizing Garcia’s work other than being creative. Beginning with the starting few sentences of the house of the spirits, he acknowledges that they do belong to Garcia’s book (Antoni 16). The tone and technique used in Allende’s starting passage is a like to that of Garcia. This he refers to as â€Å"the language of the magic realism†. This he suggests is because as Allende tries to realize her own language in her writing, she ends up using Garcia’s already established language. It is ironical to, also note that, from his analysis, the last few sentences from Garcia’s book are from Allende’s book. As Antoni compares the two novels, it is revealed further that though Allende is attempting to make a difference between her novel and that of Garcia, there are some parts that do not make a big difference (Antoni 19). For instance, she stipulates in her first sentence that the writing of the novel is 50 years after the occurrence of the events in the novel. Garcia, on the other hand, writes that Buendias were prophetically written by Melquiades a century before the events. This implies that Garcia’s book is in the jurisdiction of the mythological time whereas Allende’s book is more of ancient than legendary (Antoni 20). Antoni further gives instances in the two novels that prove of Allende’s alleged plagiarism. In one instance, he views the characteristics of Tio Marcos found in Allende’s novel being obtained from Garcia’s Melquiades. This is because the two characters die, and are resurrected, they are adventurers, they bear the magical books, an d are astronomers among other similar characteristics they acquire. This implies that Allende’s novel fetches so much information from Garcia’s novel (Antoni 25). An instance where Allende is imitating Garcia knowingly iswhere; Clara insists that names should not be repeated in the
