"Background and Overview. Kevlar is an industrial textile that is most commonly known in the manufacture of bulletproof vests; however, it is also used in the manufacture of composites, and fiber optic and electromechanical cables (Seewald, 1991). Industrial textiles refer to the manufacture of such fabrics as asbestos, glass fibers, carbon fibers and Kevlar, which are produced for the automotive, aerospace sectors of industry (Martin, Penn & Scattergood, 1991). Following the success of nylons in such applications, aromatic nylons known as aramids were created through the condensation of a diamine and terephthalic acid (this is a carboxylic acid that contains a hexagonal benzene ring in its molecules). The close packing of the aromatic polymer chains resulted in a strong, tough, stiff, high-melting fiber that was suitable for use in radial tires, heat- or flame-resistant fabrics, bulletproof clothing, and fiber-reinforced composite materials. DuPont first began to produce Nomex (its trademark for poly-meta-phenylene isophthalamide) in 1961 and Kevlar (the trademarked name of poly-para-phenylene terephthalamide) in 1971 (Stevens & Kauffman, 2004)."

Abstract
This paper explains the importance of the sacrament of baptism and explains how we can see the sacrament of baptism, its effects and the way it leads a person to salvation. The paper is divided into 3 chapters: 1) the historical background of the sacrament of Baptism, 2) the celebration of the sacrament of baptism 3) the theology of Baptism.
Outline:
Introduction
The History of Baptism
The Celebration of Baptism
Baptism: Gateway to Salvation (Theology of Baptism)
Conclusion
From the Paper
"The name baptism came from the Greek noun baptisma which means "the dipping, washing", less commonly 'Baptismas' stemming from the verb 'Bapto' which means to dip or "immerse". In the New Testament this verb is used in the literal sense (Lk 16:24; Jn 13:26, Acts 19:13). From this is derived the iterative from ... which, in classical Greek was used in the literal sense of "Dipping" and in the figurative sense of being over whelmed" with sufferings and miseries.1
"The basic verb is Greek bapto, meaning "dip in or under", also "dye". In the New Testament this word occurs only rarely and always with its literal sense, as in Lk 16:24. It never has the sense "baptize". The form baptize is the term which in different constructions is employed in the New Testament for "baptize". This verb can have varied but related sense as "immerse" sink, drown, go under, sink into, and bathe". The range of meaning adds to its suitability for and act which itself has different comotations and cab be given, in the context of the gospel, such a richly diversified significance. The noun for baptism is baptisma, which occurs only in the New Testament, only in singular, and only for baptism. The term seems to denote not only the external act but also inner meaning and force. Thus the baptism denoted may be that of the Spirit as well as water, and even the baptism of cross.2"

Abstract
This paper discusses the history and development of the universal automatic computer, the UNIVAC. It describes the new possibilities that were opened up with the UNIVAC for companies and organizations in the US and shows how the UNIVAC paved the way for further funding and development of computers that have led to the modern digital age.
From the Paper
"The UNIVAC entered the public spotlight when CBS used it to cover the 1952 presidential election. Reports vary, but UNIVAC predicted the outcome of the election at around 8:30 PM the night of the election after only 1-5% of the votes had been officially counted (Cho, 2004; Deagon, 2001). Onlookers, even at Remington Rand, were dubious that the computer could produce accurate results with such a limited amount of data so quickly. Despite this skepticism, the programming and computational prowess of the UNIVAC ultimately proved accurate. The prediction it made was based on the available counted votes, the history of returns in presidential elections, and past voting habits of people throughout the nation. UNIVAC's original prediction was that Eisenhower would best Adlai Stevenson in the election by a significant margin. UNIVAC predicted 438 electoral votes would go to Eisenhower and only 93 for Stevenson, with 100 to 1 odds in favor of Eisenhower (Cho, 2004)."

Abstract
The paper begins by briefly discussing the path-breaking S-Net and then proceeds to look at the NetWare 286 and its successor, the NetWare 386. Finally, some time is devoted to looking at the NetWare 4.x and some of the reasons why Novell fell from grace in the middle part of the last decade of the twentieth century. The paper shows how by carefully reviewing the changes that were made as each new product was pushed onto the market, it becomes clear that some important technical issues failed to be addressed time and again.

Abstract
This paper details the history and development of the Universal Automatic Computer or UNIVAC, which is described as a significant chapter in the history of computers and computing technology. According to the paper, the UNIVAC opened new possibilities for companies and organizations in the nation to use the revolutionary computing hardware to perform calculations on large data sets. Additionally, the paper notes that the UNIVAC demonstrated the worth of computers beyond military applications and paved the way for further funding and development of computers that have led to the modern digital age.
From the Paper
"The UNIVAC, or Universal Automatic Computer, is a significant chapter in the history of computers and computing technology. Though it was still a vacuum tube monstrosity by today's standards, at the time of its creation, UNIVAC was a quantum leap over the computing machines that had come before such as ENIAC. Weighing in at a sleek 8 tons, UNIVAC was the first computer capable of being effectively produced for commercial applications. Previous models like the ENIAC were almost solely the domain of the United States military. The UNIVAC opened new possibilities for companies and organizations in the nation to use the revolutionary..."

Abstract
This paper emphasize different aspects of language that show it to be an important factor in human history, using the history of the English language as an example. The paper delves deep into the roots of the English language and, point by point, shows that language was crucial in the development of the history of humanity.
From the Paper
"There were several historic events that brought on these changes. One was the work of Shakespeare, who has become a key player in the relating of the history of the English language. Another was the invention of printing, which helped to unify the language under a common reading and writing system, which led to a somewhat unified speaking system. Early Modern English then later on turned into Present Era English, which was helped along and distinguished by several things. First the publication of English dictionaries again helped to unify the language as a whole (Roberts 429). Also the development of an English grammar system, which allowed for a somewhat uniform way of teaching English to children and preserving the language as well (Roberts 429)."

Abstract
This paper presents a detailed examination of the history of calculus. The writer takes the reader on an exploratory path through the origins of mathematics and then on to the history of calculus. The people who are credited with its invention as well as the forms that it took are all included in the discussion.
From the Paper
"The history of mathematics is one in which the topic follows the actual subject. Mathematics are taught by building on foundational blocks. Each block is taught and mastered and when that is completed the next block is introduced. The origin and history of mathematics follows the same path. The history of calculus is perhaps the most interesting of the mathematical techniques. The history and origin of calculus is founded in philosophy as well as science and it is one of the most fascinating of the mathematical theories and practices."
