Abstract This paper looks at stem cell research using embryos. The author discusses the benefits of this type of research such as combating disease in the future. The author argues in favor of this type of research as he believes that this is a breaking step for medicine and provides counter-active arguments for the immorality and illegitimacy that is attached to embryo research.
From the Paper "Since the dawn of mankind, humans have struggled to understand how and when life begins. Through countless developments in science and medicine, a much clearer understanding of the origin of life exists, as well as how the body itself works. Scientists of today have observed, in test tubes, the very first stages of life. And now scientists have discovered a new way to harness their knowledge of the origins of life in a way that promises to revolutionize medicine forever. Stem cell research is itself still in its infancy. In 1998, scientists at the University of Wisconsin and at Johns Hopkins University isolated and successfully cultured human pluripotent stem cells for the first time ever ("Fact Sheet"). These cells possess the potential to develop into nearly any type of cell in the body, including muscle, nervous, bone, blood, or skin."
From the Paper "In 1952, frogs were the first animals to be successfully cloned, but society yawned, barely noticing, this significant scientific milestone or its future implications. July 1997 provided living proof of the first mammal (sheep), named "Dolly" ever cloned from a single adult cell. Scientists in the U.K and Japan claim to have cloned pigs and bulls. Japanese researchers have actually grown in test tubes the eyes and ears of a frog using its own embryo cells. The reality of human cloning is now but a scientific inch away from permanently altering how humanity values itself. "
Abstract This paper argues that hybrids are a more possible than not solution for the future. It explains how they offer many unique features including a better fuel economy and cleaner emissions. This contributes to the hybrids' growing popularity and, as a consequence, major automakers are producing their own hybrid models which include sedans, trucks and SUVs. The writer states that currently, these vehicles are more realistic than using fuel cells or diesel. The writer summarizes by claiming that all of these reasons point to the conclusion of hybrids as a definite part in the future of cars.
From the Paper ""If everyone in the US drove a hybrid instead of a traditional car, we could save roughly 1.6 billion barrels of oil a year" (Mihm 1). In the quest for cheaper gasoline and a cleaner environment, the one answer that comes to mind is the hybrid. The hybrid, a gasoline-electric car, seems to be the solution for the future. With lower emissions and better fuel economy, hybrids are thrilling consumers and environmentalists. Because of the unique features of these cars and its popularity among owners, several major automakers are following Toyota and Honda by producing their own hybrid model. This is starting a hybrid revolution whether it's for a sedan, SUV, or truck. With other fuel options such as diesel, all-electric, and fuel cells falling short, hybrids may have a secure spot in our future."
Abstract This paper discusses the history, background and the complicated ethics regarding human cloning. The author looks at the science of cloning, pros and cons of cloning and argues that cloning is beneficial in the long run.
From the Paper "There is no other topic in health care with more potential for controversy than human cloning. I decided to write my paper on human cloning for this very reason, it will be an even more controversial issue than abortion in the future for my generation. Indeed, cloning is a topic for the future but this future is much closer than many people would like to believe. Many have deep religious and ethical reasons for wanting a total ban on human cloning. However, there are also many people, including some scientists, who believe that the possible benefits of human cloning outweigh the risks by a huge margin. Cloning has become an issue within the past 4 years due to the realization that it is possible to clone a human being."
Abstract This paper explores an emerging technology known as the glass cockpit and explains the human factors that influence the implementation of this technology. This discourse describes the theoretical issues of the glass cockpit technology and the human factors associated with the invention and subsequent implementation of the technology. It also focuses on the advantages and disadvantages of the technology. The writer investigates the development of the technology and compares the glass cockpit technology with the traditional cockpit. It also discusses the military and civilian uses of the technology. Finally it explores the future trends of the glass cockpit.
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)"
Abstract This paper looks at some of the ethical issues surrounding the use of cloning. This paper looks at Dolly, the sheep, the first cloned mammal and discusses how the field has progressed since 1997. The paper also discusses the ethical issues that have come up in discussions about human cloning since the field is still so new and fells that many of the concerns expressed are a result of the unknown. The paper details the different arguments against human cloning , as well as the potential scientific advances that may come as a result of its use. The author argues that human cloning and genetic engineering may eventually gain more acceptance as did IVF, birth control pills and other medical procedures which were also challenged when they first were introduced.
From the Paper "Bioethics, which is the study of value judgments pertaining to human conduct in the area of biology and includes those related to the practice of medicine, has been an important aspect of all areas in the scientific field (Bernstein, Maurice, M.D.). It is one of the factors that says whether or not certain scientific research can go on, and if it can, under which rules and regulations it must abide by. One of the most recent and controversial issues facing our society today is the idea of cloning. Dolly the sheep, was the first mammal clone, and was born in February 1997, in Edinburgh, Scotland. After considerable of news coverage, genetic engineering of DNA was in the spotlight. The world has had heatedly discussions over the issues surrounding cloning ever since."
From the Paper "Introduction
Costs associated with inventory make up one of the most critical cost areas within an organization. Whether the company manufactures goods or sells finished products, inventory carrying costs and their component parts can represent a significant portion of the company's cost structure. In addition, having the wrong amount of inventory on hand can result in severe difficulties. This research examines a particular type of inventory management, just-in-time (JIT), and examines how JIT was implemented at Dell Computer, a leading multinational personal computer manufacturer.
JIT
Reduction of inventories is the main reason that companies have sought alternative inventory management methods. The use of smaller batches leads to..."

Conclusions
From the Paper "Recent years have witnessed the rapid development of using copper (Cu) for low resistivity electrical connections in microelectronic devices.1,2 In fact, copper is one of most commonly used pure metals in the electrical industry because of its low conduct resistivity of about 6?10-8W-m and excellent mechanical properties as well. There are various methods to deposit Cu thin films, for example, electroplating, electroless plating, sputtering and thermal evaporation can be used.3.4 The copper thin films achieved by these techniques, especially those from the electrochemical techniques, are not planar enough to promise a successful multilevel interconnection. However, in fabrication of a logic device with five or more layers, at least one layer should be perfectly planar. Lack of layer planarity may lead to severe problems for photo-lithography (such as insufficient focus depth) and dry etching in sub 0.5 mm 5. Chemical Mechanical Planarization (CMP) is one of the most effective methods in achieving adequate local and global surface planarization.6 Therefore, chemical mechanical polishing of copper attracts a lot of interests in recent years."
Abstract ""A clone is one or more identical organisms descending asexually from a single common ancestor" (Encarta 99). It is a copy or close reproduction of a DNA sequence or gene produced by genetic engineering. Genetic engineering is the alteration of an organism's genetic code, to remove characteristics of a creature that are not wanted and to replace them with desirable ones. Members of a clone are identical in their inherited characteristics except for differences caused by attitude. They have the identical genetic makeup of the parent organism. "
Abstract This paper gives some background on the genetic engineering of food. The author focuses on the dangers that stem from genetically engineered food such as possible medical side effects and repercussions to the environment. The author advocates mandatory labeling of foods with genetically engineered ingredients and looks at regulations in other countries.
From the Paper "By far the most severe environmental repercussion of GE crops is that they are a Pandora's box, once they are planted, there is no way to control or recall them. Pollen from GE plants is spread in exactly the same manner as regular pollen, and, therefore, their genetic material will quickly spread to any surrounding fields. This is one of the main reasons why is truly impossible for people to know what they are eating. An organic tomato grown a mile away from a farm that grows GE tomatoes may or may not be infected. Scientists have no way of determining what kind of effects the release of all this genetic pollution will have on the ecosystem (Davis)."
Abstract This paper looks at the different factors that need to be addressed when designing hand-held power tools. The author argues that when ergonomic factors are Incorporated into their design, there are less instances of injury, less sick days, and production is increased as a result.
From the paper:
"A well-designed tool can provide a number of important advantages that can be immediately noticeable. Ergonomically designed hand-tools contribute to the prevention of injuries which will then increase productivity on a continuous basis, improve the quality of the products produced, and reduce the absenteeism in a company for health related causes. Properly controlling the ergonomic factors such as the physical loads a person exerts (through the design of the handle and trigger), vibrations, and noise of the hand tool will decrease the chances of an injury occurring on the job."

This paper provides a look at the principles of New Urbanism, a land development movement designed to combat ugly urban sprawl, by redeveloping inner cities and/or making the most efficient use of open space development.
Abstract This paper examines the topic, New Urbanism, synonymous with the term "Smart Growth" which is a way to develop land efficiently, whether it may be a new development using open space land, or a redevelopment of a part of an inner city- called "infilling". The paper explores the ten principles that New Urbanism is guided by and gives examples of developments across the country that have used this method and prospered.
From the Paper "Small, picturesque towns like Nantucket and Savannah dot the eastern landscape of the country. These towns are the illustration of the principles America was founded upon: closeness, unity, community, and family. The neighborhoods were compact and had mixed-uses. Everything a family needed in the normal course of the week was all within walking distance. There was a town square where the townspeople met and talked. In the youth of this country small developments like these were common, however in the last 50 years America has seen development practices take a turn for the worse. The current practice of building suburbs nationwide sprang up after World War II, and development has sacrificed hundreds of thousands of acres to this practice ever since. Now the majority of U.S. citizens now live in automobile-oriented, unattractive suburbs full of strip malls and four-lane roads with four-foot sidewalks. Although this is still the norm, there is a new kind of development that is making an impact on the way communities are built. This new method, called New Urbanism or Smart Growth, has caught on in the last 20 years and is now popping up all over the country. New Urbanism is a way to combat ugly urban sprawl, replacing it instead with small, interconnected communities that are pedestrian-friendly and contain housing, work places, shops, entertainment, schools, parks, and other amenities essential to the daily lives of residents, all within easy walking distance of each other. New Urbanism involves using the principles it sets forth to fix and redevelop existing cities, called "infilling", as well as to create new, high-density, compact towns and villages."
Abstract This paper describes, compares and contrasts manual and automatic transmissions, defending the thesis that manuals are better than automatics in several aspects including efficiency, expense and pleasure. The paper argues that manual transmission is better than automatic because it is more pleasant to drive, giving one full control of the vehicle (about 62% of the sports cars sold in the U.S. are manual), it is more efficient and safe because it requires the driver's full attention and is cheaper because it requires less gas.
From the Paper "Ever since the automotive revolution began, there has been a battle between manual and automatic transmissions. Many differences can be pointed out, and when the two are objectively compared, one can easily see that manuals are superior to automatics. One of the strongest impressions that foreigners get when they first visit the USA is the fact that so many Americans prefer to drive automobiles with automatic instead of manual transmissions. In Europe, where the average cost of gas is $4 per gallon, most people, almost without exception, drive manuals because automatics need more fuel. Driving a manual there is an axiom ? no one questions it, and everyone believes it is better. However, blind belief is not right. That is why a few arguments will be stated in defense of manual transmissions. Although cars with automatic transmissions may appear appealing to the customers, the truth is that manually operated automobiles are superior. Automatic cars are so easy to operate that they deprive the driver of the delight of feeling in control of the car. That ease also allows the driver to have a quick cup of coffee or a nice talk on his or her cellular phone while driving. In addition, when a driver has only one pedal and the steering wheel to worry about, he or she is more apt to fall asleep. These distractions make them dangerous on the road."
