"ELECTROMAGNETIC INTERFERENCE (EMI) WITH AIRLINER ON-BOARD COMMUNICATIONS AND NAVIGATION SYSTEMS ASSOCIATED WITH THE USE OF PASSENGER-CARRIED PORTABLE ELECTRONICS EQUIPMENT
Introduction
Background on the Problem
Persistent reports have linked electromagnetic interference (EMI) with airliner on-board communications and navigation systems with the use on such aircraft of passenger-carried portable electronic equipment (Nordwall, 1993, p. 32). The problem is exacerbated by two developments--portable electronic equipment has proliferated, and the smaller size and low-voltage characteristics of modern aircraft electronics causes them to be increasingly vulnerable to EMI. In response to these events, some a..."

"The engineering definitions, methods of analysis, and significance of many elements of the study of fluid mechanics are presented.
Definitions and Fluid Properties
Fluids can be either liquids or gases, and fluid mechanics "refers to the study of the behavior of fluids, either at rest or in motion." Nunn elaborates that there are "two main physical properties defining a fluid: density and viscosity." Nunn then subdivides fluid mechanics into three major categories of ideal fluid flow, in which density is constant and viscous effects are negligible; compressible flow, in which density varies from place to place throughout the fluid and viscosity effects are trivial or..."

From the Paper
"The Mars Global Surveyor is an American spacecraft which went into orbit around Mars on September 12, 1997 to conduct a detailed photographic survey of the planet beginning in March 1998. The spacecraft used a formerly untried technique called aerobraking to turn its initially highly elongated orbit into a circular orbit by dipping into the outer atmosphere of the planet. This was a $273 million project that began sending important data about the planet's surface at a quarter of the cost of the Mars Observer mission, which had failed in 1993 (Lawler, 2000).
Mars has long been a particular goal for space exploration. The planet has excited the human imagination, perhaps because of the many literary and dramatic works that suggested civilizations on Mars, and certainly because of the long-ago.."

From the Paper
"While the invention of the internal combustion engine revolutionized transportation in the 20th century, it also brought with it many inherent problems, including a dependence on natural resources (oil) and air pollution, both of which have spurred research in recent years to find an alternative power source to run public and private forms of transportation. The best alternative is the battery-powered electric vehicle, but the limits of current technology severely restrict its practicality in terms of range, performance, cost, and flexibility (Siuru, 1998).
"High fuel efficiency and performance, lower emissions of greenhouse gases, and reasonable maintenance requirements are sought after features for engineers working to develop electric power generation systems for a free-piston internal combustion ..."

From the Paper
"Primitive man used simple machines such as levers, the inclined plane, the pulley, the wedge, the wheel, and axle. It was considerably later that man discovered that it was possible to employ liquids and gasses to exert forces at a distance, leading to the introduction of a complex array of new machines based upon what is now known as fluid mechanics and/or hydraulics (Hydraulic pressure, 1998). A machine that transmits pressure by a liquid is a hydraulic machine, a technique discovered by Pascal, who found that a pressure applied to any part of a confined fluid transmits to every other part with no loss. The pressure acts with equal force on all equal areas of the confining vaults and perpendicular to the walls' in other words, pressure results from the interactions of pipes and cylinders and produces motion of various types (Hydraulic pressure, 1998). While hydraulics are regularly..."

From the Paper
"In order for the stakeholders in the shuttle program are to be satisfied that a disaster of the Challenger type will never occur again the decision making process that allowed the disaster must be explored. It is fair to state that certain kinds of decisions that stood on their own merit should no longer have credence.
In the broadest possible sense, despite the tremendous accomplishments of the engineers, scientists, and management involved in the shuttle program, the greatest mistake in respect to Challenger was enthusiasm. The groundwork for any project from ditch-digging to landing a rocket on the moon, must be laid with careful, methodical work that allows for no shortcutting..."

From the Paper
"Genetic engineering is being used more and more in agriculture to produce plants which are resistant to disease and thus increase crop yields. This research paper will examine methods used to produce transgenic plants and an experiment which produced genetically engineered rice with resistance to sheath blight.
"Transgenic plants are produced for three major reasons. (Glick and Pasternack, 1998, p. 427). Firstly, transgenic plants often improve crop yields by inducing resistance to pests and other factors which affect the yield, or improving the ornamental value of plants by developing new colors, or strains resistance to certain climactic conditions. Secondly, transgenic plants can be used to produce medically and commercial important proteins and metabolites in large amounts under..."

Abstract
This paper draws a line at the edge of ethics, focusing on genetic engineering. It uses the book "Frankenstein" by Mary Shelly to illustrate some its points and to draw the reader to certain conclusions, while giving a summary of the book.
From the Paper
"Cloning, genetic engineering, DNA mapping, these words are no longer terms of science fiction, but terms that exist in our lives. While we, as a people, applaud our scientific achievements, there are questions that remain. Is it dangerous? Can there be unpredictable outcomes? What will happen?"

Genetic Engineering, 2002.
A discussion of the ethics of Genetic Engineering.

Abstract
This paper gives an insight into the principles of genetic engineering since its first concept by an Austrian monk named Gregor Mendel. It discusses how selective engineering of genetics is invaluable to the health and happiness of humans and how the importance of this issue has played second fiddle to the arguments, for and against genetic engineering for years. Examples are provided to argue the positive side of regeneration and to show how in time, genetic disorders such as 'Down Syndrome' and 'Multiple Sclerosis' could be made diseases of the past.
From the Paper
"Even though there are a lot of risks, the possibilities of what we can do are endless. Genetic engineering should be allowed to progress because of the benefits for human beings outweigh the consequences. For example, cows could be genetically cloned to produce milk with medications in it. This means that vaccination shots and pills would become obsolete. Babies could be brought up immune to diseases by simply being fed milk. Imagine what this could mean for people who live in countries like Somalia. Whole countries could be made healthy and immune to disease."

Pile Testing, 2002.
A description of two major types of pile tests-- pile-load test and integrity test.
2,330 words (approx. 9.3 pages), 4 sources, MLA, $ 71.95
»
Click here to show/hide summary
Abstract
This paper introduces and discusses pile tests methods - pile-load tests and integrity tests. The integrity tests include the acoustic test and the seismic test method. For each test the procedure and interpretation are discussed. Real-world cases are investigated and pictures are presented. Advantages and disadvantages of each method are concluded in the end.
From the Paper
"In carrying out a maintained load test to determine the load capacity of a pile, it is suggested that it is necessary first to estimate the load capacity so that a suitable loading and reaction system may be provided, and then to define some physical event by which "failure", and hence the ultimate capacity of the pile may be recognized. Among the commonly used definitions of the ultimate load capacity are: First--The load that causes a settlement equal to 10% of the pile diameter. Second-The load at which the rate of settlement continues undiminished without further increment of load, unless this rate is so slow as to indicate that settlement may be a result of consideration of the soil. For example, Qu in Figure 2 could be taken as the ultimate load."

Abstract
The treatment of wastewater is divided into three main categories: Primary treatment, secondary treatment and tertiary treatment, where each stage contains several steps. This paper examines this purification and treatment process and explains each stage step-by-step.
From the Paper
"The primary treatment stage involves the removal of physical contamination which includes grit, grease and solid particles. The first stage in this is a screening process, which filters our large particles. The next stage is grit removal, this is a settling stage where grit is allowed to settle out of the water under low flow conditions (Manahan 226). The final stage of the primary treatment is grease removal, which is achieved by allowing the wastewater to settle, with the grease materials floating on top. This top layer is then scraped off."

Abstract
The paper explores the dangers of genetically engineered food products in the marketplace. It traces activities of anti-genetic engineering groups and their relationship with biotech corporations. Legal and political implications of the industry are also studied.
From the Paper
"The new biotechnology of genetic engineering initiates thoughts of a glow in the dark bunny, plants that eat poison, plants that contain pesticides and some medicines. New cures for diseases or solutions to problems that plague the world, such as starvation, are the promises made by the many supporters of this technology. However, many people are skeptical, because they know little of the potential side effects it may have on the people who eat or use the genetically modified products. An article printed in the Christian Science Monitor entitled "Europe Invites Biotech Debate" by Peter Ford on September 11, 2001, explains the position of the public and the European Commission concerning genetically modified products while keeping his view of the issue from influencing the way that he writes. Karen Charman, on the other hand, lets her views of government control give her a clear agenda as to how she states the United States' position in this debate in her article, "Spinning Science into Gold." Comparing the biotech issues between "Spinning Science into Gold," and "Europe Invites Biotech Debate," one sees that, unlike European nations, corporations in the United States maintain exclusive control over genetically engineered products. Clearly there is a need for government intervention to regulate corporations."

Abstract
The paper shows that the construction of piled foundations is a skilled operation, and calls for a high level of training and experience. Though they are not infrequent, when faults are discovered in some important piles, the consequences could be severe. This paper describes two major types of pile tests: Pile-load test and Integrity test. The integrity tests include acoustic test, and seismic test method. For each pile test, the procedure and interpretation are discussed. An actual case is investigated and pictures are presented.
From the Paper
"Acoustic test:
"Advantages: The system scans the pile concrete radially for a distance of approximate 100mm around the drilled hole or installed tube. The method is relatively rapid, some tens of tests being possible daily.
Disadvantages: Pre-selection is generally required as it is usual to install purpose made tubes in the pile for the equipment. It is necessary to employ plastic tubes for this purpose, with the attendant risk of collapse, steel tubes being unsuitable for single hole logging. The installation of the tube adds to the reinforcement steel in restricting free concrete flow and may in itself lead to defects. Poor bonding of the tube to the concrete may yield an anomalous response. Unless a hole is drilled, it is not possible to inspect right to the base of a pile by this method. Specialist interpretation is generally necessary."
