Abstract
This paper argues for and against the use of genetic engineering from a number of perspectives. It shows that, even though God has given man the knowledge to manipulate genes in such a way as to eliminate almost any blemish, the question remains whether this is the right thing to do. The paper mentions that, on the one hand, the scientific potential is mindboggling; but on the other hand, many fear that the power of eliminating certain types of genes, could be blown out of proportion.
From the Paper
"The alteration of the genetic structure of any organism is done by means of Genetic engineering that provides characters beneficial or pleasing to the individual performing the alternation. In other words it is a treatment of the DNA or RNA pool (Sarah. 2002). For instance, the most greatly well known example of genetic engineering is the sheep Dolly that was cloned in the year 1996. Here, in order to create Dolly, the scientists took out cells from the udder of a pregnant, six year old ewe and then these cells were put into not related host eggs that had their DNA separated. Thus, as an alternate of creating one fertilized egg, a reproduction or a duplicate of an adult animal was made (Sarah. 2002)."

Abstract
This paper discusses extensively the history of wheels, starting from its origin, up to its common use at present, which is for transportation. This paper also concerns itself with the development of automobile manufacturing and industry, since through many years, cars that have evolved into various models and functions haverelied on wheels as the important part of its structure to keep an automobile functioning.
From the Paper
"The origin of wheels was said to have started during the Sumerian civilization, which was during the 3500 BC. However, there have been studies that prove that wheels are not only utilized, but also essential to other people or civilization primarily because these people think of the wheel as a symbolic material that represents intangible things. In fact, it was discovered that early Mesoamericans treat wheels as sacred objects, representing the ?cycle of life, death, and rebirth? (Wirth 1996). The Mesoamericans were known to associate wheels with the ?supernatural, religious world,? thus establishing the fact that aside from the present utilitarian value of wheels, this object is also essential for its symbolic value."

From the Paper
"The term ?Glass Cockpit? describes a cockpit in which all of the displays are painted onto the glass of a computer screen. Glass cockpits replace a number of, switches, gauges, and indicators with automated display systems. The use of computers to manage the on-board systems, allows pilots to describe what they want to observe at the exact time that they want to observe the indicator. Glass cockpits have allowed contemporary aircraft to require only two crewmembers as an alternative to the three needed by traditional cockpits. (Krell)"

»
Click here to show/hide summary
Abstract
The paper discusses Pitts Special planes which are used specifically in aerobatic competitions and have been in operation since 1943 when Curtis Pitts designed his first special plane. The paper examines the features and purpose of Pitts S-2B which is one of the modern versions of the original Pitts Special aircraft.
From the Paper
"The range of Pitts Special then grew steadily and some other models were made available which were all used for aerobatic competitions and thus quickly gained popularity in the industry for their unique features and designs. Not only were these planes stronger than many other counterparts, their designs were also developed keeping in mind their purpose. This colorful range therefore attracted media and public attention when they participated in national air-shows and exhibitions. But it is important to know that Pitts Special range became more popular during the 1960s era when Curtis Pitts developed some constructions sets and sold them to amateurs for a price of $125 per set."

Abstract
The following paper examines how the Pitts planes revolutionized aerobatic performance and competition. The writer discusses how flying in the 60's was redefined with the introduction of the S1-S Pitts Special, a small, powerful and agile biplane that dominated the sport during the period. This paper argues that the tiny Pitts was a marked contrast to the large Yak-52 monoplane used by the USSR and other eastern block countries.
From the Paper
?Pitts Specials, in all their varieties, are eager to please. And they respond well to a loving touch. They become transparent and take on the personality of the pilot, making him, or her, the composer. The Pitts lets them write the melody as they alone hear it? (Davisson).
While it is still a very popular training and show aircraft, the Pitts S-2B is no longer in production, is has been superceded by the Pitts S-2C. Replacement parts can still be purchased from Aviat Aircraft of Afton, Wyoming. ?To many pilots, their Pitts Special becomes more than an airplane. It becomes a living, breathing entity that completes them both as people and as pilots. Maybe that's the real gift of Curtis Pitts. It's not so much the victories, as what he has added to so many lives. Few people make that kind of contribution to the world. But then, few people have designed the likes of a Pitts Special.?

Abstract
This paper discusses in detail the safety of the Suburban Utility Vehicle (or SUV). The author uses the science of physics and engineering and the relationship between a car?s relative mass and center of gravity to understand to understand the problems. The author states that increasing the track width is the only way to make the vehicles more stable but that may modify the appearance of the car.
From the Paper
"What can be done to remedy these concerns over the Wrangler?s design? To answer this question, one must do more than simply understand more about the safety features of this particular vehicle or of SUVs in general. One must turn to the science of physics and engineering and the relationship between a car?s relative mass and center of gravity to understand what the risks are for each vehicle and how best to potentially remedy those risk. Or, to put the question in another way, if Einstein were an auto mechanic, what type of Jeep Wrangler would he like to be riding in? How might he modify the vehicle?s design?"

Click here to show/hide summary
Abstract
With air travel and the highways becoming increasingly congested, the need for an efficient, fast and comfortable mode of alternative travel has been felt in many countries of the world. One of the possible solutions is the Magnetic Levitation Propulsion System or high-speed trains called the Maglev train (short for magnetic levitation). The recent question mark over the safety of air travel and the fear of flying created among the general public by the events of 9/11 has renewed interest in the Maglev technology. This paper discusses how the Magnetic Levitation Propulsion System works and briefly overviews its history of development. The different types of designs developed so far, the cost of developing such systems, and the potential for its expansion and use in transportation systems in the United States and all over the world is also discussed. The author uses photographs and plan drawings to illustrate points.
From the Paper
"We all know that the opposite poles of a magnet attract while the like poles repel each other. This is the basic principle on which the Magnetic Levitation Propulsion System works. In magnetic propulsion systems, powerful electromagnets are used. The three basic components of a maglev train system are: A large electrical power source, metal coils that line the track or guide-way, and large magnets attached to the underside of the train. There is no conventional engine in maglev trains. Instead, the force for propulsion is achieved by a combination of the magnetic fields created by the electrified coils in the tracks (called the guideways) and the guideway walls."

DNA and Aging, 2002.
This paper looks at the effect of DNA on the human body.
2,005 words (approx. 8.0 pages), 13 sources, MLA, AU$ 77.95
»
Click here to show/hide summary
Abstract
This paper discusses the role that DNA plays in the aging process. The author looks at several studies that have been conducted over the years that look at how different types of drugs and disease affect the aging process. Some of the studies involved a look at such issues as cholesterol and the effects of cholesterol-lowering drugs on both the human and animal populations. The paper also looks at Vitamin K, the loss of DNA from the human heart as a person ages, how a person's alcohol and tobacco use affect their longevity. In all of these cases, the paper looks at both the male and female populations in order to illustrate how all of these different aspects affect an individual's DNA and as a result, their life expectancy.
From the Paper
"The third category, accretional defects, results from the accumulation of waste materials composed of nonfunctioning of poorly functioning parts of the body system during aging. These involve the liver and kidneys. The human liver must absorb 70% of the dysfunction before they appear in routine blood tests (Strehler), since it is one of the many jobs of the liver to remove bilirubin from the blood. (Bilirubin is a natural by-product of red blood cells at the end of their life cycle.) A high-level bilirubin translates into jaundice and is harmful to the brain if high levels accumulate in the blood. But if the liver?s own removal cells are malfunctioning, bilirubin accumulates in the blood and damages the person?s overall health. (Strehler). The kidneys are even hardier : 90% of them must sustain the damage and be damaged themselves before abnormalities are detected in blood tests of kidney function (Strehler). This means a person may have kidney trouble for many years without knowing it, only until his or her kidneys are 90% damaged, during which the signs of illness begin to show."

Abstract
The author of this paper shows how the technologies critical to the U.S. for new weapons systems have become increasingly available in the global marketplace and thus are accessible to its potential adversaries as well. The paper provides an extensive review of the artificial intelligent systems currently used by the U.S. military aviation and their advantages.
From the Paper
"It is CIE's job to determine what these actions mean right now, in the current situation. This explanation is formed based on current understanding of intent, situations in the external world, and knowledge about acceptable behavior in the cockpit.
"Understanding crew intentions is really only one function of CIE that ensures human-centered RPA behavior. CIE also dynamically identifies conflicts between the current crew intentions and RPA activities as posted by RPA's internal Task Network Architecture (TNA) scheduler. The TNA is the mechanism that coordinates RPA aiding activities. CIE can identify potentially counterproductive RPA behaviors and transmit an indication of conflict and also type of conflict so that the RPA Task Network can possibly identify a way to complete its scheduled tasks without being counterproductive to the crew's objectives."

What is the Sound of One Cell Thinking?, 2002.
This is a review of an article on stem cell research.
1,025 words (approx. 4.1 pages), 1 source, MLA, AU$ 44.95
»
Click here to show/hide summary
Abstract
This paper is an analysis of an article by John Carey and Ellen Licking, "The Stem-Cell Debate Just Got Thornier" that appeared in the February 11, 2002 issue of "Business Week." The paper uses information from the article to define stem cells, and to give an overview of the debate over research using human embryos. The issue of virtual embryos and some of the controversial issues surrounding the possible use of any of this research to cure many diseases such as Parkinson's, leukemia or the regeneration of lost limbs.
From the Paper
"Stem cells are present in the early stages of embryonic development, and have the ability to develop into any other sort of cell. This makes them useful tools in healing degenerative diseases where extra heart, brain, or other cells are needed. Until recent developments, it was believed these cells could only be harvested from human embryos, which sparked a great deal of ethical debate. Many people believe that human life begins before birth, and do not approve of the idea of grinding up little humans and injecting their cells into sick adults. Federal research money is given only to programs that use existing cell lines and forbids harvesting new stem cells. Cloning is also in line to be chopped, which will further prevent scientists from creating ?bred for the slaughter? embryos from which to harvest identical stem cells for their patients."

Abstract
This paper details a brief history of boron composites from its earliest applications to recent developments. It studies the application of boron in composite epoxies and fibers and the use of these materials in airframe manufacturing. It includes figures showing usage of Boron composite. It concludes that boron has been very successful in aircraft manufacturing if the costs can be brought down.
From the Paper
"Compounds of boron, most notably from unfinished borax ore, known as Tincal, were exported from Tibet in olden times. Historically, boron has been used for refining gold and silver in Arabia, ceramic glazes in China, and embalming in Egypt.
"Boric acid, a mild antiseptic, was isolated in the laboratory by chemistry professor William Homberg in 1720. Sir Humphrey Davy, a British chemist, and two French chemists, Joseph Gay-Lussac and Baron Louis Th?nard, discovered the element, boron, in 1808 concurrently. However, it took another 155 years before science turned its focus from borax to boron, and began to reveal the secrets of this mysterious and valuable element."

Nuclear Energy, 2006.
An argument in favor of using nuclear energy.
1,855 words (approx. 7.4 pages), 4 sources, MLA, AU$ 72.95
»
Click here to show/hide summary
Abstract
This paper argues that the disadvantages associated with nuclear energy are not as great as some of the disadvantages of other forms of energy. Specifialy, the paper argues that nuclear power provides much economic growth and does not degrade the environment unless, of course, an accident of some sort, such as Three Mile Island in 1979, were to occur. The paper further argues that nuclear power is obviously a very sustainable source for the generation of electricity.
From the Paper
"In the early 1970s, the cost of a two-unit nuclear plant was about $1 billion, due to the great amount of materials needed for construction. For example, at one plant in the mid-1970's, 270,000 cubic yards of concrete, 17,000 tons of reinforcement bars, 11,000 tons of steel, 250,000 linear feet of large boring pipe, 240,000 feet of small boring pipe and 6,700,000 feet of cable was needed for construction. Presently, the cost has skyrocketed, due to inflation and the increased price of materials."

Titanic: Commotion in the Ocean, 1999.
An analysis of the technical reasons to explain why the Titanic sank.
1,197 words (approx. 4.8 pages), 9 sources, MLA, AU$ 50.95
»
Click here to show/hide summary
Abstract
This paper discusses the theories that explain why the RMS Titanic sank on her maiden voyage. It focuses on the design flaws of the ship, the inferior steel that was used in its building, the speed that the ship was traveling when it hit the iceberg and the overconfidence and negligence of both builders and crew. It combines all of these issues to explain how the disaster could have occurred.
From the Paper
"The Titanic disaster was one of the most catastrophic events in the history of travel on the seas. Some ministers preached that the disaster was actually a godsend in disguise, compelling people to abandon their self-absorption, and punishing them for their reliance on technological progress. (Lord 113) Not only did the tragedy mark the end of a universal sense of security, but it was also a turning point in the implementation of additional safety measures. The International Ice Patrol and Coast Guards now closely monitor meandering icebergs to keep them clear of the steamer lanes, and every liner must have sufficient lifeboats for all boarding passengers. (Lord 104) Never again will mankind invest its trust in a few thousand tons of steel and rivets. Like the author Michael Harrington states in his novel Their Eyes Were Watching God, "If there is technological advance without social advance, there is, almost automatically, an increase in human misery, in impoverishment." The saga of the Titanic is a classic example of technological failure causing profound death and destruction."

Abstract
This paper is a discussion on how America's interstate highways have affected its commercial growth over the years. Included in this study are the following topics: post roads and early travel routes, growth and sprawl benefits and effects, right-of-way and eminent domain, the role of the railroad in human and freight travel, the role of the automobile, and a short study on Route 66 in its heyday.
Outline:
Early European Models
Early American Travel Routes
The Railroad
The Automobile
Route 66
Infrastructure Issues
The Interstate's Role in Growth and Sprawl
From the Paper
"The highway, or Interstate as it is formally called, has facilitated a drastic growth in American lifestyle, planning, and design, in urban, rural, and suburban regions. Some contend that the invention, production, and utilization of the automobile created the need for a broad network of interstates, while others say that this relationship was formulated the other way around. However, most will agree that the highway is a more efficient means of travel and of transporting goods. Additionally, it creates opportunity for growth along its corridors--from suburbs to shopping malls to rural rest stops, many businesses have boomed due to their proximity to the highway."
