...benefits of technology. Therefore, we are sometimes depending on technology too much. For example, one person would not move from house. He can order something to eat by telephone. He can also buy clothes by Internet. This kind of service is used delivery system, so he doesn’t need to move from his house. This is one of benefits of technology called transportation. It’s not only that man. It can refer to us. If we don’t have a telephone, it’s too inconvenient. We can’t talk to people who live a long distance from our house, even in the same town. If we don’t have a TV or radio, we can’t get exact information about the world. If we don’t have a car, we can’t go too far. It’s so inconvenient, especially in the USA. However, the most important thing for me is the airplane. If we didn’t have airplanes, I couldn’t come to this ELC and I couldn’t write this composition. These are just example I imagine. I can present more examples if I want. Now, I want to write about fuel. It is important to use this product for technology. The most famous fuel is oil. Oil can be changed into gasoline and oil gas. Oil is used in most vehicles and for heating. However, the oil is said to be able to last only this century. Therefore, we have to harvest the oil and need to look for some new fuel instead of the oil. Next, I want to notice electricity. It is one of the important power sources for using technology. Electricity is made in many ways. For example, it can be made by using natural power sources...

...Abstract According to the No Child Left Behind Act of 2001 (NCLB, 2002), every student should become technologically literate by the time they reach the eight grade. Evidence exist within the Houston County School District that A grant was written in 2009 requesting two million dollars to bridge the digital divide within our community. The grant was approved and a motion to coordinate a curriculum develop project has been accepted by the schools board committee. The goal of this project is to integrate technology among all middle schools that is at present an underserved community with limited access to technology. All stakeholders will be compiled into committees and a point of direct contact will be delegated for each group. After all decisions have been made and the implementation phase begins, the program will receive formative and summative evaluations that will continue to occur as for the duration of the program. Power in Technology The Houston County School District, plagued with a high crime rate, high unemployment, and extreme poverty, has found itself deficient of the skills needed to perform day-to-day-tasks. Many of the people in this community have been impacted by deficiencies passed down from generation to generation. For example, some of the women who currently receive governmental assistance (public housing, welfare and food vouchers) are descendents of those who received the same assistance. This sometimes extends as far back as...

...Technology Too Powerful? The year was 1997. The date, August 4th. Skynet, a military computer system used as a global defense network, was activated and given command over all computerized hardware and systems belonging to the United States military. The system also had control over military bombers and the US nuclear arsenal. Skynet was created to eliminate human error and respond quickly to enemy attacks. The system taught itself and by August 29th, gained artificial consciousness. The operators panicked after realizing the capabilities of Skynet and attempted to shut it down. Skynet viewed this as an attack and responded. It’s reponse was the extermination of the humans. Nuclear missiles were launched at Russia and Russia responded with a counter-attack. Over 3 billion people were killed that day. The humans were enslaved by Skynet’s army of machines but started a resistance movement. Today, we are still at battle attempting to over power the machines and regain our world. (The Terminator, 1984) The year today is 2015. We are all living outside of enslavement from machines and our world has not been destroyed by nuclear weapons. What you just read was the basis for the 1984 movie, The Terminator. Technology had been made too powerful, gained self-awareness, and took over the world. Thankfully, that is not our world. However, will it be in the future? Technology may not have progressed as fast and as far as the movie thought that it would by now, but it’s getting better by...

...Living in a world where humans are no longer required to perform any menial task, while they have technology to keep them entertained as they do their work means that humans are too dependent on technology. It also means that they don’t know how much control technology has towards them. One of the most common threads in Harrison Bergeron, August 2026, and The Pediatrician is that technology is taking over and destroying society. Technology is is becoming one of the greatest culprits in all of humankind. Any society shouldn’t let the use of technology control their lives for it can decrease a human’s brain function, it can control the lives of others all of a sudden, and it can rule all of society the more it’s being used. In the movie, Harrison Bergeron, the main theme of this film is that “The power of technology can decrease a human’s brain function.” It’s the year 2053. An American government forces all citizen to wear headsets that decreases their brain function. Apparently Harrison Bergeron shows signs of intelligence. He’s been held back for four years and still keeps receiving A’s when C’s are the desired grade. He is believed to be a...

Waves travel and transfer energy from one point to another, often with little or no permanent displacement of the particles of the medium (that is, with little or no associated mass transport); instead there are oscillations around almost fixed locations. Wave power refers to the energy of ocean surface waves and the capture of that energy to do useful work — including electricity generation, desalination, and the pumping of water (into reservoirs). Wave power is a form of renewable energy. Though often co-mingled, wave power is distinct from tidal...

...ALTAIR EQUIPMENT CO.,INC. Water Treatment Technologies WARMINSTER, PA. 18974 DEAERATORS Why Deaeration Corrosion of iron or steel in boilers or boilers feed water piping is caused by three fundamental factors: 1. Feedwater temperature 2. Feed water ph value 3. Feedwater oxygen content Temperature and ph value influence the aggressiveness of corrosion. The higher the temperature, and the lower the pH value the increased aggressiveness of the feedwater. The dissolved oxygen content of the feedwater is a large factor in determining the amount of corrosion that will take place. The presence of oxygen, and other non-condensable gases, in the feedwater is a major cause of corrosion in the feedwater piping, boiler, and condensate handling equipment. Deaerator Principles Deaeration is the mechanical removal of dissolved gases from the boiler feedwater. There are three principles that must be met in the design of any deaerator. 1. The incoming feedwater must be heated to the full saturation temperature, corresponding to the steam pressure maintained inside the deaerator . This will lower the solubility of the dissolved gases to zero. 2. The heated feedwater must be mechanically agitated. This is accomplished in a tray deaerator by first spraying the water in a thin film into a steam atmosphere. Creating a thin film reduces the distance the gas bubble has to travel to be released from the water. Next, the water is cascaded over a bank of slotted trays, further...

...For the vast majority of human history, the arts have played an important role in society. With the recent developments of technology, more specifically, mobile phones and television, art appears to be fading as most people spend their time watching television, playing video games, and texting. Despite this, the great works of literature of the past and present will last forever, never disappearing due to technology. Personal technology never lasts more than a few years, but the greatest pieces of literature have the power to last through centuries. Lasting over the years, the novel As I Lay Dying by William Faulkner is a perfect example of the power that literature has to transcend time. Published in 1930, this work has not lost to technology....

...The use of Composite Materials in Aerospace, Wind Power and Automotive Technologies Introduction A composite is a multiphase heterogeneous material comprising of fibres that are embedded in a matrix [1], [2]. A composite is unlike an alloy because in an alloy, the other components have been produced by naturally occurring changes. There is a diversity of types of composites currently available, since “it is possible to design materials with property combinations that are better than those found in the metal alloys, ceramics and polymeric materials” [3]. The main ones focused on in this essay are polymeric matrices, metal matrix composites and ceramic composites, and their applications in the aerospace, automotive and wind industries. (1) Brief Fundamentals of Composites 1.1 Concise History [4] The search for alternative materials arose from growing technological and environmental demands for more efficient and sustainable components for industrial purposes. It was in the 1940s when the military first placed a priority on finding more high-strength and lightweight materials for their vehicles. The main materials used at that time were metallic, and while they were functional, they were often prohibitively heavy, so that the engines could not carry as much as cargo as they preferred, whereas the composite materials were much less heavy, as shown in Table 1, and when compared to non-composites, even steel, carbon based composites have a higher tensile strength. At the bottom...
