From the Paper
"Introduction
Glass has been around since the beginning of time (Glass Online, 2001). Glass is made naturally when rocks melt as a result of high temperatures such as in volcanic eruptions, and also comes from extraterrestrial sources. Man-made glass was produced dating back to around 3500 BC in Egypt and Mesopotamia. The basic components of sand were originally contained in glazes used on pottery and it is thought that sand may have got into the kilns used for firing and combined with soda to form a colored glaze. The oldest glass vessels date back to the 16th century BC and were found in Mesopotamia. Hollow glass-making evolved around this time in Egypt and glass making was also emerging independently at this time in Mycenae (Greece), China and North Tyrol."

Abstract
The paper introduces the concept of Nanotechnology, and considers the usage of both proteins and nucleic acids as molecular components of Nanomachines. Their pros and cons (including strength, speed, comparison to macro-scale materials) are considered in detail, and a conclusion is drawn based on these observations.
From the Paper
"Our modern technology builds on an ancient tradition. Thirty thousand years ago, chipping flint was the high technology of the day. Our ancestors grasped stones containing trillions of trillions of atoms and removed chips containing billions of trillions of atoms to make their axe heads; they made fine work with skills difficult to imitate today. They also made patterns on cave walls in France with sprayed paint, using their hands as stencils. Later they made pots by baking clay, then bronze by cooking rocks. They shaped bronze by pounding it. They made iron, then steel, and shaped it by heating, pounding, and removing chips. We now cook up pure ceramics and stronger steels, but we still shape them by pounding, chipping, and so forth. We cook up pure silicon, saw it into slices, and make patterns on its surface using tiny stencils and sprays of light. We call the products "chips" and we consider them exquisitely small, at least in comparison to axheads."

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."

Cardiac Technology, 2002.
This paper discusses the field of cardiac technology, especially the areas of heart pumps and pig heart transplants.
1,615 words (approx. 6.5 pages), 3 sources, $ 52.95
»

Abstract
This paper explains that the new technology heart pumps, such as Left Ventricular Assist Devices (LVAD), assist the heart permanently instead of temporarily as the traditional pumps were used. The paper describes the use of animal parts for transplants especially the pig heart, which closely resembles the human heart, and the problems of organ rejection. The author believes that successful cardiac technological developments will lead to further developments for other parts of the body.
From the Paper
"Traditional pumps were meant to be temporary solutions to most heart problems. These small pumps were implanted into the chest cavity of patients with the sole function of assisting the heart?s own pumps. They helped to keep the rhythm of the heart?s beat, regulating the pumping of blood throughout the body, and helping the heart in times of need. Traditional heart pumps were expected to help the heart recover to the points at which they could be removed and the heart would operate properly on its own. Their other function was to help keep the patient alive until they eventually moved up the waiting list for donor hearts and got a heart transplant. "

Abstract
This paper examines the recent breakthrough in genetics and reproductive technologies. It questions that , as a society, are we ready for these advancements. The paper argues that genetic engineering has great potential, which outweighs the risks, and it illustrates both sides of the argument in order to appreciate the promise and danger associated with these new genetic and reproductive technologies.
From the Paper
"The advancements that have come in the field of genetics and human reproduction are probably amongst the most controversial which have arisen in the history of the human race. These advancements actually present us with ways that we can redefine the human race itself. The mapping of the human genome, the possibility for human cloning, the developments that have arisen in the field of assisted fertilization, and the general idea of engineering human beings in order to fight diseases and other negative human conditions, have raised many, many arguments. Never before have we had so much control over our future and our nature. There are many promises that have been made in support of the development of reproductive technologies, all of which point to a better world as the result of the advancements that have been made. There have also been many people who have voiced opposition to the advancements, as they feel that they will result in negative affects that would undermine our entire system of values and ethics.The thesis of this paper is that the developments in human reproductive technologies are very important and offer us many benefits, but we are not completely ready either socially or technologically to deal with the advancements that have come so quickly."

Abstract
This paper discusses the social change that is a result of new reproductive technologies. It investigates the effects on the concept of the family, women's bodies, and on our very lives as a whole. The paper investigates the social relevance of cloning, in vitro fertilzation, and surrogate motherhood.
From the Paper
"We live in an age in which technology is playing a greater and greater role in the construction of our society and in the ideologies and perspectives that are applied to understanding social phenomena. Technology has revolutionized the way we look at communication and media, transportation, the work place, and social institutions. It is not surprising, then, the new technologies are having an impact on the way we view the basic social unit - the family. The founding of new reproductive technologies (NRTs) has redefined and continues to redefine the meaning and construction of the family in our society. It has also contributed directly to the changing implications of women?s roles in the family and society. While some argue in favour of these changes and their positive social influences and implications, others argue against the control which these technologies represent over individual?s bodies. The following paper will explore these arguments in order to demonstrate the overall thesis that NRTs are changing the way we look at ourselves, the family, women and society as a whole. The impact of these technologies socially is growing more and more, and in order to fully understand their significance we need to examine their social relevance."

Abstract
PIC, A Pre-IKE Credential Provisioning Protocol, has been introduced in the IP Secure Remote Access working group of the IETF in order to provide for simplified user authentication and credential provisioning prior to IPSEC IKE negotiation. This paper performs a critical analysis of the proposal, examining, among other things, PIC working draft, course relevance, IPSEC deployment issues, strengths, weaknesses and alternatives.
From the Paper
"The PIC working draft proposes one of the best solutions for bootstrapping strong credentials for IPSec networking solutions without changing existing IP Security standards. PIC can theoretically be implemented and developed independent of IPSec, wireless and VPN standards yet provide an integrated component into the infrastructure solution. PIC clearly provides a window of opportunity for extending and encouraging increased deployment of secure networking solutions in the wireless and VPN market spaces."

" Basic Oxygen Steelmaking
Abstract
Steel is a heterogenous material which consists primarily of iron. The steelmaking process involves removing carbon and other impurities from pig iron and scrap. During the nineteenth century, Henry Bessemer noted that this could be achieved by blowing air through the molten metal. It wasn't until the mid-twentieth century though, that metallurgists began using oxygen instead of air. Top-blown basic oxygen converters eventually gave way to combination top- and bottom-blown furnaces. The introduction of this technology created concern about the effects of oxygen on finished steel products. Various studies have clearly demonstrated how oxide inclusions can adversely alter the physical properties of metal. Fortunately, basic oxygen.."

"Background
Injection molding is a processing technique which converts thermoplastic and thermosetting materials into a variety of products. Approximately 25% of the 13 billion pounds of thermoplastics sold in the United States in 1971 were injection molded (Rubin 1).
Injection molding equipment may be configured in a wide variety of options. Selection of the specific type of equipment is determined by the requirements of the molding job and by the degree of versatility desired. Each type of injection unit and its associated clamping unit has its own specific advantages and limitations. The current trend is toward reciprocating screw and two-stage screw pre-plasticizer equipment (Grandilli 34). This is largely because of increased capacity and versatility when..."

"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..."
