"Precast Prestressed Concrete
Concrete is a stonelike material obtained by allowing a carefully proportioned mixture of cement, sand, gravel (or some other aggregate), and water to harden (Winter & Nilson, 1972, p. 1). The bulk of concrete consists of the fine and coarse aggregates (p. 1). The cement and water interact chemically to bind them together (p. 1). One mode in which the substance finds common usage is as precast prestressed concrete. This building material can be employed in the construction of a variety of different structures.
In general, during the mixing of concrete, more water is added than is necessary for the binding reaction to occur (Winter & Nilson, 1972, p. 1). This extra water gives the concrete an initially liquid character (p. 1). In liquid form, concrete can..."

"Introduction
The most important use of asphalt today is in road construction (Zakar 148). When it has been properly mixed with the correct aggregate material it becomes highly suitable for all kinds of pavement applications. It is also widely used to prepare the base of roads.
Asphalt road construction is multi-layered in form. The subgrade layer is itself covered by a base cover upon which is laid a final coating. Early classical base courses consisted of a handmade, packed layer which was then graveled. Later this technique of construction was replaced, on a global basis, by a flexible asphalt layer in which asphalt gravel or sand asphalt had been mixed (Ibid. 149).
Asphalt as a road construction and/or road repair solution..."

From the Paper
"Genetic engineering is the term given to the process of producing living forms with altered characteristics by alteration of their genes, usually by implantation of genetic material from some other species into the DNA of the plant or animal to be modified. This report outlines the principles on which genetic engineering is based, and briefly surveys some of its economic and social implications.
Since genetic engineering burst on the public scene in the 1970s, few areas of scientific endeavor have been so subject at once to exaggerated fears and to exaggerated hopes. Genes are the fundamental building blocks of life, in the sense that it is essential a creature's genes that determine its nature, whether man or mouse or mulberry tree. To artificially manipulate genes thus rouses deep fears of scientific monkeying with the essence ... "

From the Paper
"Although efforts have been made to find alternative fuel sources, at this time the United States continues to be dependent upon oil for the majority of its energy needs. Unfortunately, the nation does not produce enough oil domestically to meet this need. Therefore, the U.S. must import foreign oil from unstable regions of the world such as the Persian Gulf. Studies indicate that the United States imports half of the 6 billion barrels that it needs each year, at an annual rate of approximately $42 billion. It has been noted that as much as 50 percent of the nation's current trade deficit is due to this large-scale importation of oil. Because of this situation, it has been argued that the United States should make a greater effort to exploit domestic oil resources. Although there are many onshore sites for oil, the ... "

"This study will examine civil engineering education and professionalism for the purpose of making civil engineering more accessible and significant from the viewpoint of those not familiar with the field or its practitioners.
An event which has thrust civil engineering into the headlines around the world is the Persian Gulf War and the destruction carried out by Iraqi soldiers in Kuwait. Specifically, the issue involves the role of civil engineers in rebuilding Kuwait after that destruction.
A number of reports indicate that civil engineers--both military and civilian--are spending much of their energies and expertise on rebuilding a palace for the emir of Kuwait and putting less work into rebuilding the basic systems for sustaining the lives of ordinary citizens."

From the Paper
"Glass blocks are non-loadbearing masonry units which are made by molding two sections of glass and bonding them together. The interior of the block is hermetically sealed in order to prevent condensation. Most such blocks allow light to pass through, but they are often designed to distort the view to ensure privacy. Some blocks, however, are relatively transparent, and special blocks have been designed to direct light upward or downward for certain building requirements. Bulletproof blocks have also been developed.
The recommended sizes for glass blocks, always square, are 6 inches, 8 inches, and 12 inches, each with a recommended 1/4-inch mortar joint. Round-ended blocks are also available to cap the sides or tops of block walls. Other sizes and shapes are also available. The mortar-bearing surfaces of the glass blocks have ... "

Introduction
"The development of the railroads was a key element in the expansion of the United States and in the economic well-being of the nation during the nineteenth century and into the twentieth century. The railroad was a transportation and communication marvel compared to anything that had existed previously. It crossed the territories of the nation and made it possible to travel from one end of the country to the other or to send mail and goods along the same routes. The development of the railroads was itself a matter of business expansion on a grand scale, starting with small lines and ending with vast networks of tracks which nurtured cities and towns all along their length. In terms of business history, the development of the railroads was not only the first big business venture in America but also..."

From the Paper
"The purpose of this research is to examine the human factor in aviation and the degree to which pilot error is the cause of airplane accidents. This will require a brief discussion of the available facts and statistics on air travel as well as a review of the reasons why this happens, even among seasoned pilots, and why the numbers are growing.
The modern airliner is a marvel of technology, as safe as man can make it. The statistics convincingly point to the safety of flying over other means of transportation. "In 1978, U.S. airlines completed 99.99991 percent of their flights without a fatality (Norris 11). In 1979 around 800 million passengers travelled by air around the world, and only 1,267 of them (plus 149 crew members) were killed, making the odds about 565.000 to 1 (Norris 11). These figures have remained relatively constant, (...)"

From the Paper
""Pilot Error" is the identified cause of a large fraction of aircraft accidents, and the role of pilot error (and other human errors, e.g. by ground controllers) is tending to increase as improvements in aircraft design, weather forecasting, and other technical areas of aviation reduce the role of structure failures and other "unavoidable" causes of aviation mishaps. By the 1970s, fifty-five percent of accidents were attributed to pilot error (Hurst 13). Clearly, the human factor, in various forms, plays an ever increasing role in air accidents.
Human error may take many forms, from gross displays of bad airmanship to unconscious errors which can be attributed to fatigue or to unconscious perceptual errors. When human error is identified as the primary or contributory cause of an accident, our principal concern is not to fix blame, but to identify (...)"

From the Paper
" This paper presents a discussion of the role of the facilities engineer in facilities planning for production organizations. Manufacturing productivity has been a serious problem in the United States since the mid-1960s. Although some improvements in productivity have been recorded in the mid-to-late-1980's, the country's significant international trade deficit illustrates the continuing need for greater improvement.
One of the factors underlying the productivity problem is the set of economic interactions wrought by the American economy from industrial to post-industrial (Bowles, Gordon, & Weiskopf, 1984, p. 41). The change from industrial to post-industrial, however, will not eliminate production organizations from the (...)"

From the Paper
"Corrosion, in terms of drilling operations, was responsible for at least 70 billion dollars in losses in 1975, or 4% of the gross national product. Reportedly, 10 to 45% of that loss was preventable (Bertness and Chilingarian, 1983, 559). Understanding the causes of corrosion in terms of drilling operations is?tantamount to saving time and money. The trends towards drilling of deeper wells, the use of higher strength steels, the presence of higher stress levels and the use of lower pH drilling fluids all contribute toward increased corrosion susceptibility.
The destruction of metals by corrosion is caused by direct (...)"

"After careful evaluation of our two major products, we narrowed our focus to one, the Portable Compressed Air and Hydro-pneumatic Jack. Once we did this, we wanted to ensure that the product focused on customer needs. In order to understand where our product fulfilled customers? needs we identified the latent or hidden needs as well as explicit needs using a Product Survey and Response. We then used the result of the survey to provide a fact base for justifying the product specifications. We created an archival record of the needs activity using a table to ensure that no critical customer need was missed or forgotten."

Abstract
In today?s world, almost all forms of transportation rely on some form of an onboard device as a means of propulsion. This paper discusses the various types of laser propulsion (ALP, SLP, CW, RP, LSD, LSC, etc.) currently available and their development in the context of modern technology. It also addresses the scientific aspects of laser propulsion, with accompanying explanations of physical phenomena supporting such devices. Examples are illustrated with pictures and diagrams.
From the Paper
"Due to the plasma basis of this method of propulsion, a liquid or gas is mandated as the type of fuel to be used. Early tests utilized hydrogen and nitrogen as reactant gases and liquids, however it was soon found that plain air worked nearly as well4. As a result, air-breathing lightcrafts quickly became the standard in LP research, for any reactive faults of air in comparison with other gases are dismissible when the lacking cost, and natural abundance of air are taken into account."

Abstract
A thorough explanation on the make-up and functions of the Russian Kilo-Class 636 attack submarine. The paper includes information on the design, depths, propulsion, engines and speeds, technology, weapons, Soviet operations and inventory of the submarine.
From the Paper
"Stealth is the most important element of a submarine. The Kilo was, at one time, the stealthiest submarine in the world. If necessary, she could completely shut down all systems, and just float beneath the surface, in order to avoid detection. A nuclear boat cannot do this because if the reactor were shut down, it would take equipment only available in port to start it up again."

"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..."

"The Technological Development & Application of the Machine Gun
This research traces the technological development and application of the machine gun. John Ellis wrote The Social History of the Machine Gun from a general perspective of the development and application of technology. Ellis worried, however, because machine guns, to use his words, head become an ?indispensable aid? not only to soldiers and the police, but also to terrorists.
For better or worse, the technology of the machine gun is now a part of human existence. The insinuation of machine technology into human society began in 1884, when the first effective fully automatic machine gun was developed and patented in the United States by Hiram Maxim. Multi-barreled weapons, such as the Gatling Gun, had been used earlier in the..."

"Social Responsibility of Engineers
Introduction
The social responsibility of engineers may be discussed at both general and specific levels. Further, when discussing the issue at either the general or the specific level, the assessment may be limited by the interests of the assessor or the audience. For the greater part, this essay approaches the assessment of the issue from the general level, with the discussion limited by the following major questions: How much control do engineers have over the social impacts of the technologies they create? Should engineers be regarded as having a greater influence over the direction and social consequences technological change than other groups of societal players? In the development of answers to these questions, the issue of the social..."
