Our group members are Matthew Miller, Isaac Scott and Kenny Scott. Since our topic Is Societys Reliance on Technology, it is important to look at the development of technology over history. Technology had to start somewhere, and It will continue to evolve and advance, so these will be important sub-topics to look into. Not only did technology have Its origins, there were Individuals who advocated and supported Its development. Two key figures in the technological frontier were Steve Jobs and Bill Gates. We will write a custom essay sample on Societys Reliance on Technology or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page We will take a look at some of the stances they took in pushing technology forward. Isaac Scott will be covering these two sections. In handling the aspect of reliance, there are two facets of technology that must be analyzed: useful technology that Is essential to our everyday lives and outdated technology which had Its purpose at one point in time but is no longer useful. Matthew Miller will be exploring these two facets of technology. Once we have explored those two sub-topics, it is now necessary to explore the reliance part of our overall topic. Where do we as a society place the most emphasis on technology? Is it possible to survive without these tOf6 technology disappeared? Could we survive as a society? What would we need to do to establish a successful future without technology? Kenny Scott will explore these important issues. In order to evaluate societys reliance on technology, we must first look back to where technology came from. Once we determine where it came from, we can track its evolution over the last several centuries. The earliest record of invented technology is dated around 2400 B. C. It was around this century that the abacus was first introduced in ancient Babylonia. The abacus was one of the first calculators introduced to man. Several centuries later, in 300 B. C. , Pingala invented the binary number system . Just before the turn of the millennium in 87 B. C. , the first device to track galactic movements is invented and named the Antikythera Mechanism. As the world moved out of the B. C. era, the world of technology would begin to advance at a much more rapid pace. Liang Ling-Can invented the first truly mechanical clock in 724. One of the most significant inventions of all time, the movable printing press, was introduced in China sometime in the early 1000s. In order to counter the biological effect of deteriorating eyesight, the earliest eyeglasses ere introduced in the late 1200s. Johann Gutenberg would improve upon the Chinese movable printing press model with a new version that included the ability to organize the type alphabetically. One of the greatest inventors in our history, Leonardo Da Vinci, would become notable around the 1500s for his many technological revelations. Galileo would also become quite famous for many of his inventions, including the pendulum, the thermometer and the microscope. Other inventions continued to make their appearance during the Renaissance era, such as he telescope and adding machines, but the next serious step in the evolution of technology took place around the beginning of the Industrial Revolution. The Industrial Revolution saw the transition from rural, farm life to urban, factory settings. The steam engine was introduced around the eighteenth century. This invention would revolutionize the industrial setting as well as transportation across land and water. Benjamin Franklin made significant contributions with his use of the lightning rod and the stove. Steam power began to make a more immediate impact in factories and mills towards the late 1700s. Another significant invention to come out of the Industrial Revolution was the cotton gin. The field of medicine saw breakthroughs when vaccinations were introduced in 1798 and nitrous oxide a year later. Transportation took a leap forward with the inventions of the steamboat and the locomotive, and later the steam locomotive. Computers are an everyday necessity in our lives now, but they had to start out somewhere. One of the first computers introduced was in 1822 by Charles Babbage.

Conditionals Besides If and Unless

Conditionals Besides If and Unless Conditionals Besides If and Unless Conditionals Besides If and Unless By Mark Nichol If and unless are common conditional conjunctions employed to express conjecture and uncertainty, but a number of other words and phrases that perform similar functions are discussed in this post. â€Å"Should you† is the future conditional form of â€Å"do you,† seen in formally polite requests such as â€Å"Should you have any questions, please do not hesitate to contact me.† It is more flexible than â€Å"if you,† which is strictly conditional in the present, in inviting the audience to contact the speaker/writer at any time, not just now. â€Å"Had you† is an example of a subject-auxiliary inversion, employed in statements such as ‘Had you bothered to ask, I would have told you.† The implication of the sentence is that the audience did not do something that, if he or she or they had, would have achieved the stated result. â€Å"If (noun/pronoun) were† statements pertain to possible but improbable occurrences or to recommendations, as in â€Å"If you were to open your eyes, you would find what you were looking for.† A more formal version of this form is â€Å"were (noun/pronoun) to (verb),† as in â€Å"Were we to think otherwise.† Several words or phrases impose conditions or set limits, such as â€Å"As long as† (less formal) or â€Å"so long as,† (more formal), â€Å"only if,† â€Å"on condition that,† and â€Å"provided† or â€Å"providing† (or â€Å"provided/providing that†). The conjunction or is used conditionally to establish an alternative possibility to a condition or state: â€Å"Hurry up, or you’ll be late.† Otherwise, as used earlier in this post, is a pronoun; as a conjunctive adverb, it serves the same function as or (but notice the difference in punctuation): â€Å"Hurry up; otherwise, you’ll be late.† (Some writing guides accept the punctuation used with or.) Suppose and supposing apply to what-if situations: â€Å"Suppose that I were to say no- what would you do?† â€Å"Supposing that I were to say no, what would you do?† Suppose also pertains to proposing an idea, as in â€Å"Suppose I pay for dinner, and you buy the movie tickets?† In â€Å"if only,† only appears as an intensifier to express a strong wish for a different condition or state, as in â€Å"If only you had told me before.† â€Å"If so† and â€Å"if not† pertain to opposite potential affirmative and negative conditions or states, respectively, when the condition or state is known: â€Å"Do you plan to attend the event? If so, click on yes. If not, click on no.† Even is also used as an intensifier with if, but unlike in the case of only, it precedes if; it pertains to extreme or surprising conditions or states, as in â€Å"Even if I were to believe you, what would you expect me to do about it?† Want to improve your English in five minutes a day?

Individual project 1 lab science - Essay Example nd water occurs as a result of percolation processes that involve water movements from the surface into the inner profiles below the earths surface where it is banked in aquifers. Ground water sources are, however, exhaustible where infiltration rates are reduced beyond extraction rates. Case studies of four regions were sampled and used in this study to analyze various human activities taking place in four cities. Human activities such as; urban sprawl, industrialization, and the extent of deforestation were then observed, surveyed and compared with data from secondary resources. Population data was acquired form the population tallying units for the four regions and interpolated against human activities and groundwater properties. Geological surveys were then conducted to determine the quality and quantity of ground water in the four regions, and his data was as well compared to past literature records. Precipitation data was acquired from the meteorological records from eight meteorological stations in the regions. The population of the four regions had consistently increased from 1980- 2000. There was also a remarkable increase in the extent of human activities over the earth’s surface such as agricultural expansions, expansion in the sizes of urban centers found in these regions as well as the establishment of more of such. Precipitation data from meteorological surveys showed reduced precipitation amounts over the period included in the study. Ground water surveys revealed reduced quantities as well as lowered PH, increased acidity. Human activities and climate change and variability are the prime threats to the existence of underground water resources. Mans activities such as deforestation reduce the rates of water infiltration by increasing surface runoffs, as a result, the groundwater banks diminish in size in such regions. Moreover, other human activities such as industrialization and pollution (Pahl-Wostl, 2007) are very detrimental to groundwater

Effect of Blow Moulding on Bottle Weight and Dimensions

Effect of Blow Moulding on Bottle Weight and Dimensions Abstract Blow moulding, which is also called blow forming, is a manufacturing process for production of hollow-form plastic products. The present report is intended to deal with the effect on bottle weight, bottle dimensions and machine output of the various process factors. By reference to Rheological properties of plastics, the correlation between the share rate and screw speed, melt temperature, die swell, bottle thickness were discussed. Also, the influences of elongational viscosity were suggested. 1. Introduction Blow moulding, also known as blow forming, is a process used to produce hollow productions by â€Å"blowing† thermoplastic molten tube into the shape of a mould cavity. Generally, blow moulding can be divided into three main types including stretch blow moulding, injection blow moulding, and extrusion blow moulding. In this experiment, extrusion blow moulding was studied to examine the effects of process variables on bottle weight, bottle dimensions and machine output. In extrusion blow moulding, plastic particles are melted into fluid with heat applied. Then the melt plastic is extruded through a die, forming a hollow tube, which is usually called a parison. After that, the parison is captured by closing it around a mould. Next, air is pumped in to the parison when the ends of the parison keeps sealed at the mould parting line during forming. The parison deforms, forming a shape very closed to the mould. The mould is opened after the component is well cooled. Finally the component is ejected and the procedures are repeated. More and more products are made. In this experiment the plastic particles are High-density Polyethylene, the density of which ranges from 0.941 to 0.967 g/cm3. The High-density Polyethylene is preferred for production by blow moulding as it is more rigid and usually has a matt finish compared with Low-density Polyethylene. 2. Experimental Equipment Hayssen extrusion blow moulding machine Materials High density polyethylene (HDPE), Blow moulding grade, BS2581, Borealis. Procedures Firstly, HDPE particles were pumped into the hopper though a pipe. After that, the parameters of process variables and the temperatures of different zones were set according to Table 1 2, respectively. Then the machine was set in automatic mode and continuous cycle. Each group needs 10 samples, marking 1 to 10. Before the Process Variables were changed, the weight of parison extruded per unit minute was measured. Finally weight of each bottle, was measured along with thickness distribution along the length circumference. 3. Results And Discussions Experimental Results The original records including weight of bottle, bottle thickness distribution, output rate and crew speed are shown in Appendix I. In addition, the calculation of share rate and modified prison length are shown Appendix II and the general results are summarized. Experimental Discussions Influences Of Machine Variables On Bottle Weight And Dimensions Generally the bottle weight and dimensions is influenced by screw speed, melting temperature, and vent time. Screw speed. By comparing group A and group C, it is clear shown that output rate increasing with the increasing screw speed due to low viscosity and high die head pressure. By referring to the rheological properties of plastic, thickness and weight of group A should be higher than that of group C, because the higher sagging brings decreasing of weight and thickness. However, the records of the experiment do not accord with the theoretical analysis. The reason is that the machine is too old. Melting temperature. By comparing Group C and Group D, it is found that the bottles of group D are lighter and thinner than those of group C. The higher the melt temperature is, the lower the viscosity of polymer is. Lower viscosity reduces bottle weight and dimensions. Vent time. By comparing Group A and Group B, the result is that the bottles of group B are lighter and thinner than those of group A. If the vent time is too short, it will cause insufficient cooling and less sagging. Share Behaviours According to the equation ÃŽ ³= (6Q)/ (WH ²), the results of apparent share rate are given in Table 4 (all steps in calculation is shown in Appendix II). Experiments runs A B C D Shear Rate (s⠁ »Ã‚ ¹) 234.94 232.86 398.41 458.62 Table 4: Apparent shear rate Generally shear rate is related to screw speed, melt temperature, die swell and bottle thickness. Screw speed. The output rate is proportional to the screw speed. According to the equation ÃŽ ³= (6Q)/ (WH  ²), as the mean circumference (W) and die gap (H) are constant in this equation, the shear rate (ÃŽ ³) increases as output rate (Q) increases, in other words, screw speed increases. Melt temperature. The viscosity of polymer becomes lower at higher melt temperature. Lower viscosity results in high output rate (Q), which brings out a higher shear rate (ÃŽ ³). Die swell. â€Å"An increase in die swell results in a lower linear output rate. Since extrusion is usually continuous, further adjustments to the process dynamics are sometimes inevitable. Parison length sensors are available, to ease the effects of the problem†. In consequence, larger die swell results in larger output rate, which brings out larger shear rate. In one word, shear rate is proportional to die swell. Bottle thickness. Bottle thickness is related to the viscosity of polymer. Higher viscosity results in lower shear rate. So, shear rate increase as bottle thickness decrease.. Elongational Behaviours According to the equation ΔL= (Ï gtL ²)/ (2ÃŽ »), the results of Modified Parison Length are (all steps in calculation is shown in Appendix II). Experiments runs A B ΔL(mm) 0.566 0.944 Modified Parison Length (mm) 17.566 17.944 According to Table 5, it can be found that the longer the cycle time is, the longer the parison becomes. The result can be explained in this way: the parison will be elongated if more time is given under the gravity force. The elongational viscosity is influenced by molecular weight and temperature. High molecular weight and high temperature cause a decreasing of the elongational viscosity. 4. Conclusions Blow moulding is a manufacturing process for production of hollow-form plastic products. Process variables have the effects on bottle weight, bottle dimensions and machine output. Specifically, high screw speed, low melt temperature, and short vent time results in the increasing of bottle weight and thickness. High screw speed, high melt temperature, large die swell and thin bottle thickness lead to high shear rate. Longer cycle time results in larger parison length. High molecule weight and high temperature cause a decreasing of the elongational viscosity References [1] A. W. Birley, B. Haworth and J. Batchelor, Physics of plastic, Hanser, 1991 [2] Edwin G.

Anthem – Ayn Rand

Anthem by Ayn Rand is a disturbing book. It is disturbing in the sense that it opens the reader eyes to a world without individuals. A world without the notion of me, my, I, but only with us, we, ours. This world is one of a collectivist society. Collectivism is based on principals of the â€Å"common good. † Everyone pitched in towards this common good, but in order to do that society could not have any out-liers. Thus, individual rights were taken away. This story is one of hope that shows that no matter the situation the human spirit will continue to fight for itself. There are many strong quotes in this book that further the image of the collective society and show how one young man, Equality 7-2521 fights in his own mind against what society tells him. These images connect the book with outside ideas by not only telling the reader what happens when collectivism goes to far, but by showing the reader what a collective society would look like. One such quote is â€Å"The only thing which taught us joy were the power we created in our wires, and The Golden One. This passage is very significant. The reason being Equality 7-2521 realizes that he does not find joy in society. He finds that he has received joy by his own doing and the choice he has to love one other person. It says in the book that it was considered a sin to look at a person of the opposite sex, but when Equality sees the Golden One he can not help himself. He starts to think that society is wrong. Equality does not understand how society could find the relationship he has with The Golden One sinful. It was one of those â€Å"if this is wrong, I don't want to be right† moments. Equality starts forming his own opinions about life apart from society's opinions. He comes to this realization by remembering how unhappy his childhood was because when he went to school he was whipped for being smarter than the others, and he recalled he had never been truly happy†¦ until now. He sees the connection between breaking the law, and finding happiness and realizes that maybe society isn't as omnipotent as he was taught it was. He found joy in his wires. Like a father beaming with pride for his son , Equality found an inner-joy from his creation that he had never felt before. His life up until this point had been full of oppression, and of being punished for qualities that would be praised in a normal society such as being smart, and handsome. Equality's glass box and wires are something he decided society could not take away from him not matter what. This is the first time Equality had felt true independent and he is not about to give it up. This is the first time he has gone against the grain. He chose to make the wire. He made it all by himself, not him along with 99 other people. This is the first thread of individualism that he lets shine through. It is crucially important because in order for change to occur Equality must separate himself from society completely. If Equality kept depending on society like he was then his life would simply drudge on, and his thirst for something new and exciting would never be quenched. This joy he has found in the Golden One and in his wires will drive him to take a huge leap of faith, and not be afraid to try to make it on his own. They give him the security he needs to trust in himself. The society that Equality lives in is a collectivist society. In collectivism one gives up their rights as an individual for the good of the whole. That sounds innocent enough, but when Ayn Rand takes it to an extreme it seems horrible. At one point in the novel Similarity 5-0306 states, â€Å"Men have no cause to exist save in toiling for other men. † The quote taps into the very root of collectivism and could not be clearer. The people of this society had been taught that theme from a very young age. They were taught that they were worth nothing unless â€Å"brother men† needed them. They had no right to exist on their own, that right was taken away the second it became a collectivist society. The reader saw this quote come to life through the everyday life of Equality 7-2521. He is a street sweeper who goes along everyday, all day and cleans the streets for the other people. He picks up all the trash on the streets in front of other people's businesses. And in return, all of the street sweepers are provided with food, clothes, and other necessities. Another huge point is that the society does not use money. This means they have a direct service for service system. Which means that if one wanted clothes in the society, they would need to perform a service for the tailor. Likewise, if the tailor wanted a clean street he would need to make togas for the street sweepers. Everyone is so dependent on each other that they know they can not survive in this society on their own. â€Å"The glass box in our arms, is like a living heart that gives us strength. We have lied to ourselves. We have not built the box for the good of our brothers. † This quote gives us an idea of where Equality got his courage. It took so much courage for him to break out of the detention center and go to the House of the Scholars. It took courage for him to leave into the uncharted forest, determined to find someplace he could call home. This quote is when Equality realizes that the wires he made are more than raw materials, and more then an invention, they are worth his life. They have become not only a beating heart but his heart. He knows that this is what he was living for, this forbidden something that he cannot name yet-Independence. By the rejection of his box, society pushed Equality to do what he has secretly always wanted to do†¦ leave. All of these quotes show the principals of collectivism, which was the main theme running throughout Anthem. Ayn Rand drives in the point that collectivism, although seemingly innocent squashes out any room for development in a society. She also shows the reader how the human spirit is not easily overcome.
