Abstract This study develops reliable data that fire safety and security management professionals can use in the development of models for smoke detector types and placement in high-bay hangar facilities. Two research questions are investigated in this paper and hypotheses are tested in relation to each research question. The research questions investigated were as follows:
1. What effect does bay height have on smoke detector sensitivity in a high-bay hangar?
2. What effect does the use of a draft curtain have on smoke detector sensitivity in a high-bay hangar?
Each of the hypotheses is supported by the analysis of the data. The results of the research performed for this study show that, as bay height increases (all other factors remaining equal), smoke detector sensitivity decreases. The results of the research performed for this study further show that smoke detector sensitivity is higher when draft curtains are in place than when draft curtains are not in place.
Based on these findings, the paper concludes that the use of draft curtains should be mandated in all high-bay hangars. It concludes, further, that means should be found to deploy smoke detectors at levels lower than ceiling height in bays higher than 15 meters.

From the Paper "A total of 33 full-scale fire experiments were conducted in two high-bay hangars. The two high-bay hangars were of different heights, thereby allowing the effects of height on smoke detector sensitivity to be measured and assessed. Draft curtains were used in some experiments but not in others. This approach allowed the effects of the use of draft curtains on smoke detector sensitivity to be measured and assessed. Varying fire sizes were used in the experiments."
Abstract This paper examines how advances in micro miniaturization conceived in the electronics industry, have been applied to shrinking the size of components necessary to implement pressure transducers and how the application of this technology to other domains outside of the electronics industry has also become known as "surface machining". It considers how micro machining technology can be used to fabricate chemical instruments and even miniature chemical laboratories as well as many other uses such as solid-state pressure sensors and their application in those areas associated with in vivo blood-gas biosensors.

Conclusions and Recommendations
From the Paper "Similarly, the idea of putting a conventional, general-purpose chemistry laboratory on a single silicon microelectronic device appears somewhat fictional. Regardless, the miniaturization of chemical and physical processes and their subsequent integration onto such a piece of silicon for specific scientific and/or clinical applications is today a definite reality (Freemantle, 1999, p. 27). The development of micro scale devices that are capable of processing and analyzing very small amounts of samples and reagents is gaining the serious interest of an increasingly large number of chemists, and could, potentially, revolutionize chemical analysis and synthesis methodologies in much the same way that microelectronic technology has turned upside down, the electronic and computer industry."
Abstract The paper shows that by Time Magazine selecting Albert Einstein as Man of the Century (above other contenders such as Adolph Hitler or Gandhi), we recognize that this century has been the century of scientific inquiry, scientific developments and a major shift in scientific thought - a shift so profound that it has extended beyond science to how we view the world, our place in it and our place in the universe at large. The paper explains how Einstein's theories and thoughts changed the face of science so dramatically.
From the Paper "The shift brought about by Einstein would lead to a wide variety of possibilities, from the frightening atomic bomb to nuclear power. More importantly, it involved a major shift in how we view the universe, how we explain reality on the largest (cosmological) and smallest (atomic and below) levels, and eventually how we explain the origin of reality itself. Einsteinian theory remains strong because subsequent experimentation and improved means of observation have offered support for much of what Einstein predicted."
Abstract This paper examines how nuclear power is one of the most divisive issues in America today and how opponents of nuclear power have succeeded in convincing people to oppose the construction of new plants and to fight the relicensing of old plants. It puts forth some of the arguments from both sides to support their positions and looks at issues such as the question of safety and need for nuclear power plants and the of storing nuclear waste. It analyzes how proponents of nuclear power present convincing arguments for the continued and expanded uses of nuclear power in this country and how they claim that the objections raised by opponents lack validity and are contrary to the facts and our experience.
From the Paper "The opponents of nuclear power focus on the inherent lack of safety that they believe that the use of nuclear power entails. This includes both the dangers of radiation from nuclear power plants and the possibility of a catastrophic accident. First, the opponents say that radiation levels are higher in areas around nuclear power plants, and this leads to an increased number of deaths from cancer. They cite the case of the Pilgrim Nuclear Power Station in Plymouth, Massachusetts that went online in 1988. Responding to the concerns of local residents, the state conducted a study which found that there were fifty percent more cancer cases in the five towns around the plant than there were in the rest of the state. The power company had said that people in the area would receive 400 times less radiation from the plant than they would from natural sources. Further studies showed that the risk of getting cancer was four times higher for people living within ten miles of the plant than for other parts of the state. "
Abstract This paper discusses robotics, a technology that deals with the design, construction and operation of robots that are used in numerous applications. It looks at how these applications range from industries that require accurate and repetitive tasks (such as the car and computer manufacturing industries), dangerous tasks such as diffusing of bombs and other chores that cannot be performed by humans, e.g., carrying out research on far-away planets, or walking inside live volcanoes. It provides a description of what robots are and how they work, the history of robotics, the present applications of robots, the impact of robots in our lives and their limitations as well as the future of robots. It also discusses how close we are in the development of a "bionic" man.

Conclusion
From the Paper "Although robots as we know them today are a relatively recent invention, the idea of automated machine or a mechanical man has fascinated the human mind since the ancient times. For example, the ancient Greek poet Homer in his writings described maidens of gold, who are supposed to be mechanical helpers built by Hephaistos, the Greek god of metalsmiths. Similarly, in ancient Jewish legend, robot-like servants made of clay are brought to life by a spoken charm. (Tesler) In more recent times, Leonardo da Vinci, the "Renaissance man" drew plans for a mechanical man. Eighteenth century watchmakers were also famous for making mechanical, robot-like creatures.

Abstract This paper examines how ever since an Italian physicist, Enrico Fermi succeeded in producing the first nuclear chain reaction at the University of Chicago in December of 1942 the usefulness and the drawbacks of nuclear energy have been debated all over the world. It focuses on the benefits of nuclear energy and discusses why we should indeed use it. It also examines the concerns regarding the use of nuclear power and describe ways of overcoming them.

Conclusion
From the Paper "As noted earlier, most nuclear power plants are based on the "fission" process. During various stages of the "fission" nuclear cycle there is a high level of radioactivity present. Nuclear weapons can also be made from the nuclear fuels uranium-235 and plutonium-239. These two facts have prompted a public outcry against the use of nuclear energy, even for peaceful purposes. An accident at the Chernobyl (located in the then USSR) power plant in 1986 and a 1979 incident at Three Mile Island nuclear power plant (near Harrisburg, Pennsylvania) further reinforced these concerns. As a result, the use of nuclear energy has declined in the US and most of the world during the last several years. In my opinion these concerns about the peaceful uses of nuclear energy are overblown and nuclear energy deserves a second look as a solution for the ever-increasing energy needs of the world."
Abstract This paper describes Eratosthenes' calculation of the Earth's diameter, based on one assumption and two measurements, that the Earth was a sphere and that the two measurements made are the degree of the Earth's shadow at noon at two points and the distance between those points. It outlines how this experiment can be repeated by measuring the degree of the shadows cast at two locations either directly north or south of each other at noon on the same day and details the equipment required, the measurements to be taken and the mathematical equations involved.
From the Paper "Eratosthanes used the city of Syene in Egypt as the first point. This point was selected because it was known that on noon on the first day of summer the sun was directly overhead. This was known because people observed that at this time, the buildings cast no shadows (York University). Therefore, the degree of the shadow at Syene was 0o.
Eratosthanes then needed to know the degree of the shadow at another point either directly north or directly south, at the same time of day. Eratosthanes selected Alexandria as the second city. The degree of the sun's shadow was measured and found to be 7.2o (HEASARC)."
Abstract Aristotle was a brilliant philosopher, but many of his scientific beliefs have been proven to be incorrect. One example is the fact that Aristotle believed that the earth was the center of the universe. Regarding Aristotle's views on the idea of motion, he was in conflict with another Greek thinker named Zeno who had attempted to analyze the motion of an object as a series of "still frames." Aristotle did not believe that motion could occur this way. This paper delves into Newtonian science and quantum physics and tries to understand Aristotle as a philosopher.
Abstract Mexico's viewpoint on nuclear test banning can be seen in the Nuclear Test-Ban Treaty signed in November 2001. Mexico expressed negative feelings toward France when they decided to break the treaty. Mexico does not want nuclear testing.
Abstract Resonance has many meanings in the English language. In terms of science, resonance is a participle that cannot be observed directly; at the same time, however, resonance can be a very powerful force and has been used in much cutting edge technology. In this essay, I discuss what resonance is and a number of ways in which it can be used by humanity as an aid and a powerful force.
