Technology Has Impacted Us All - 1522 Words

Diego Martinez ENGL 111 4/6/15 First DA Draft Technology has impacted us all, whether socially, mentally or physically. We now depend on this technologic improvement to run our lives for us. But we are blinded by the positive things it brings us that we do not take notice of the hazardous or negative effects it also brings to our lives or the people around us. We must always be aware of the harmful effects of the overuse of electronics, technology pretty much runs our lives these days and has been for years without us taking notice. In our homes, our work places we have computers, phones, and all these different kinds of gadgets helping us get through the day. Sometimes we are just so used to relying ourselves on technology all the time†¦show more content†¦Based on a 2010 Kaiser Foundation study showed that elementary aged children use on average 7.5 hours per day of entertainment technology, 75 percent of these children have a TV or a device in their bedrooms, and 50 percent of North American homes have the TV on all day, children now rely on technology for the majority of their free time, but are still developing sensory, motor, and attachment systems that they are not ready for the chaotic nature of today’s technology. This impact on the developing child has seen an increase of physical, Psychological and behavior disorders that people now are just beginning to notice. Young children require 2-3 hours per day of active play to achieve the adequate sensory stimulation received when touched, and or hugged. More negative effects that technology brings into our society is Cyber-bullying caused by social media being so big. Kids especially are the most vulnerable to this which the perpetrators, anonymously or even posing as other people the victims trust, terrorize individuals in front of peers. These online attacks can scar you and most likely never leave your life, or even end a life. Many victims have even been driven to the point of not wanting to live their lives

Santiagos Code of Behavior Essay - 788 Words

Santiagos Code of Behavior Exemplifying Dignity Belongs to the Conquered. Ernest Hemingway, one of the greatest American writers of all time, is known to write of his main characters having a code of behavior. The two main parts of this code are to never give up, and to be humble and respectful of others. One of Hemingways novels, The Old Man and the Sea, consists of an old Cuban fisherman named Santiago going out to sea, catching a gigantic thirty-foot marlin, but eventually losing it to the sharks. Santiago follows the Hemingway code of behavior, therefore emphasizing and supporting the theme, Dignity belongs to the conquered. Santiagos respectfulness is an example of Hemingways code of behavior. For†¦show more content†¦Within the code of behavior is a code of honor that Santiago illustrates. For example, when Santiagos left hand is cramped because he is forced to carry the load of the fishing line to his left shoulder, he simply tells the hand, Cramp then if you want. Make yourself into a claw. It will do you no good (58). Santiago does not let go of the fishing line to ease his pain because he cannot bear to forfeit his battle with the marlin. This determination to never give up is an indication of Hemingways code of honor. Also, when Santiago is without weapons, cannot see in the dark, and knows sharks are coming to attack his marlin, he asks himself what he will do and responds to his doubts by saying, Fight them. Ill fight them till I die (115). Santiago knows he has almost no chance of matching the sharks ferocity, but fights them because he refuses to quit. Once again, such stubbornness il lustrates the code of honor. In summation, Santiago has opportunities to refrain from troubles like predators or ailments, but does not because he is so honorable that he cannot bring himself to quit. Hemingways uses of respect and honor combine to illustrate that even if one loses the battle, or is conquered, they can still keep their pride, or dignity. Specifically, just before the last of the marlins flesh is to be eaten by the shovel-nosed sharks, Santiago tells him, I am sorry that I went too far out. I ruined us both.

The Skunk by Seamus Heaney Essay Example For Students

The Skunk by Seamus Heaney Essay The Skunk by Seamus Heaney is set at night in California. A man is away from his wife and while he is writing in the darkness, a skunk passes by and takes on the qualities of his wife. The themes of this poem are sexual desire, and the love Heaney has for his wife. This poem is highly conversational and heavily descriptive of the environment as well as the feelings of the poet. The poem contains academic terms such as mythological as well as words from a foreign language, such as voyeur in the poem. This poem uses the symbol of the skunk to represent the sacred and sexual relationship that Heaney shares with his wife. It is risky in that the skunk is often viewed as a repulsive wild animal but he uses this animal to make a comparison to his wife, but successful because it shows another side of relationships. It is sacred like the chasuble of a priest, and also repulsive because of its unpleasant odour. The second stanza paints the scene using self-contained end-stopped lines. The desk like softened to a brightness suited for a romantic atmosphere. There is also a reference to sex, the small oranges represent a distinct part of a womans body. At this point, the speaker begins to tense like a voyeur. The word voyeur has a negative connotation showing that the speaker is very uncomfortable with his own self-image. The third stanza is the opposite of the sentence structure of stanza 2. It uses enjambment to accelerate the pace of the poem and to increase in intensity of the poem. It creates a sense of urgency and excitement while allowing a flow of emotions. He describes the relationship he has wife his wife, the words composing and love both imply care and tenderness. While the words broaching and cask, that are often used to describe the process of wine making, focus on the value of the relationship as well as its maturity and age. There is evidence of sensory imagery used in the poem, such as snuffing, inhaling, tang of eucalyptus and mouthful of wine. Making use of the senses evokes the presence of the wife, and underscores the multifaceted and rich aspects of love and sensuality. By using the definite article the before intent and glamorous, it shows the great love he has for his wife. While he has been exiled from his wife, the skunk suddenly reminds him of her, remembering the gentle removal of clothing at bedtime and setting an erotic atmosphere. Her position over the bottom drawer searching for the black plunge-line nightdress returns to the metaphor of the skunk because of the same stance the image of his wife is in. It is however, ironic that Heaneys wife is looking for her dress when he finds her already extremely attractive without anything on. Black is the dominant colour in the poem. The colour has diverse associations with mystery, the night, a wild animal, sex as well as sadness. It is a mixture of glamour, sex and allure. Heaney also uses zoomorphicism to transfer the eroticism he derives from a skunk onto his wife. It shows the naturalness of the relationship, the animal sensuality they experience the primitive nature of sex and the skunk is used to emphasises the context.

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

Question: Discuss is 3D Printing for the Built Environment- Feasible? Answer: Introduction 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 80s and named as 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. Conclusion 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.
