Abstract
In this article, the writer points out that in order to be fully aware of what type of panel is being addressed by this study, various types of panels must be examined and understood. The writer notes that there are various types of panels that are more significant to the discussion than others, and some types of panels also have more information written about them. The writer maintains that because of this, there are panels discussed that have more information about them than other panels, but every effort is made to ensure that each type of panel has enough information collected about it to ensure that the reader has a clear understanding of the type of panel and the important information that surrounds each one. Diagrams and figures are also provided where they are available to help with the understanding of the different types of panels that are discussed.

From the Paper
"One way stiffened core panels must also be addressed as a type of panel that is important to discuss within the confines of this particular review of the literature. These panels are significant for many different types of applications, as are all of the panels that are being discussed within this review of the literature. Two way stiffened core panels will also be addressed in the next section. The subsections below, however, will address the different types of one way stiffened core panels, including Z-core, C-core, Trussed Core, and Zig Zag Core panels.
While one way stiffened core panels are important to address, it is also necessary to ensure that the different types of these panels are examined, because they all work differently and are created differently (Gdoutos, Daniel, Wang & Abot, 2001). This indicates that, while they all may work well, some of them will work better for specific types of applications, and it is necessary to be aware of what types of applications are the best choices for each particular panel."

From the Paper
"According to Bryner, elastomeric coatings are primarily based on acrylic, silicone, or urethane chemistry. Approximately 70 percent of the elastomeric coatings used in the U.S. are acrylic-based, F&S says. Some of the key competitors in this industry today include Degussa Construction Systems (Shakopee. MN), Sherwin-Williams, and ICI (Bryner, 2005). This author adds that one company saw "double-digit growth last year in this business, and expect to see the same next year" (Bryner, 2005, p. 37). This company, ICI, manufactures acrylic-based wall coatings that are primarily used on "tilt-up" buildings--a type of construction where walls are cast on-site and then "tilted up" in place--and in particular, prison buildings. The company says these coatings accounted for 2 percent of its 2004 store-sales. ICI recently reorganized its elastomeric coatings business under one brand, called Decra-Flex, Salvadore says. "We had a disjointed program, and what we've done is brought everything together," he says (Bryner, 2005, p. 38)."

Abstract
The paper relates that plastic pipes, tubing and other items are essentially a part of today's industries; they have almost replaced copper pipes and tubing, as well as aluminum and steel materials. The paper explores the dangers of PVC and examines how researchers have found that when infants are treated with medical devices that contain PVC in any form, they are inadvertently exposed to very high levels of a toxic chemical. The paper also shows that it was found that PVC can be dangerous if used while transporting compressed gases in above the ground installations, because the pipeline could rupture. The paper contends that policies and recommendations would help in the analysis, testing and the implementation of proposals and recommendations when using PVC.
From the Paper
"Mechanical testing of PVC resins would have to be carried out to find out if the combination has created a success of a potential failure. (Portnoy,199) However, the determination of the actual root cause of the failure of systems or components, like for example, the PVC tubing in an industry, can be an extremely complex proposition, because of the fact that it would involve multi-disciplinary testing and analysis. (Matco Associates inc. Failure Analysis)."

From the Paper
"Citing the example of Japan finding itself in need of coal during the 1930s, Bell reports that the Japanese simply acquired more material by invading Manchuria and appropriating their resources. This author also observed early on that the materials revolution would have a profound effect on how architects and designers selected the materials needed for any given applications, and suggested that new technologies would emerge that would allow for completely customizable materials for any given purpose. This, in fact, is what has taken place in recent years. Indeed, innovations in materials science as well as manufacturing applications that have introduced new composites and the potential for increasingly tiny applications of these substances at the molecular level through nanotechnology promise even more science-fiction-into-science fact realities.

Abstract
The paper discusses how many buildings today feature fully computerized building management systems that monitor energy use and maintenance schedules on a continuous basis. The paper shows how the trend towards this coalescence of different types of mechanical and electronics technologies has increased in recent years. The paper discusses how they help eliminate the need for human oversight, but the process is not without its challenges and constraints. The paper explores these systems and concludes that as building management professionals gain additional experience with these systems, it can be expected that additional applications will be identified that will make these systems more effective in the future.

Abstract
This paper describes a study that uses human-machine interactive features of the automobile to determine if the driver of the automobile is becoming drowsy. This mechanism is intended to provide a warning to the driver in such a situation. In this way, the drowsy driver can be kept awake by the vehicle he or she is driving, a safety feature that could prevent many accidents caused by drowsy drivers. Several studies that have approached the issue of drowsiness detection based on the use of artificial neural networks are described. The paper includes two charts.
From the Paper
"For the current project, some of this existing research may be adaptable to a new use or may provide guidance for solving the problems associated with drowsy driving. For the current project, the primary goal is to develop an algorithm, using the programs of Matlab, Simulink, and Stateflow, an algorithm that can determine an automobile
driver's relative awareness or drowsiness while maneuvering the vehicle. While this seems quite concise in summation, in reality there is much to consider when talking about the issues involved in such a development. For example, it should be asked what created the need for designing this new system and what would be the right technique in developing the system for driver use. Another question to be raised is what problems does the developed algorithm not take into account during its development, issues that may have to be considered later."

Abstract
This paper takes a look at the importance of predictive maintenance, otherwise known as condition monitoring, on HVAC systems. The paper focuses on chillers and cooling water circulation pumps and motors. The paper discusses how in the past, conventional maintenance approaches frequently resulted in equipment downtime as the result of faulty preventative maintenance systems; equipment would experience repeated failures due to over-capacity or design flaws that were not identified prior to being placed into operation.

Summary
From the Paper
"The need to identify better maintenance techniques is also congruent with the observation by Frendedall and his colleagues that, "Over the past decade there has been increased recognition that in a world class organization, maintenance is not a separate, isolated function that makes repairs and performs assorted activities as needed. Rather, maintenance is a full partner striving together with the other functions to achieve the firm's strategic goals." In the past, conventional maintenance approaches frequently resulted in equipment downtime as the result of faulty preventative maintenance systems; equipment would experience repeated failures due to over-capacity or design flaws that were not identified prior to being placed into operation. According to Thatcher, "In each case, the fix is a relatively simple one. Once discovered, however, the cost to replace or repair it can have a major impact on the organization's ability to continue to produce." The reference to "strategic" is a common theme in the scholarly literature concerning appropriate predictive maintenance regimens, and these issues are discussed further below."

Abstract
This paper looks at gene expression profiling which is defined as a basic research method that effectively measures messenger RNA that has been made up of many different genes belonging to many different cell types. It discusses how this technology is being widely accepted and used as a diagnostic test to help the technician to easily identify the various subgroups of tumor types and to help predict which patients would better respond to treatment, and also which patients may be at an increased risk of a relapse of cancer.
From the Paper
"Any cells, within an organism, like for example, within a human being, works especially in order to increase the basic functioning and efficiency of that organism. For example, Nerve cells, or in other words, neurons, are capable of expressing neuron specific proteins, and this would allow it to perform neuron duties more efficiently. Similarly, skin or epithelial cells have their very own and specific proteins, and this enables them to work better. It must be noted that both neurons as well as epithelial cells possess the genes-encoding for neural and epithelial-specific proteins, and this makes sure of their effective and efficient and protective functioning. However, each cell can only express that particular gene that it may require, and not any other tissue specific genes. What this may be taken to mean is that a given DNA sequence can only provide specific information about what 'could be', and not what actually 'is'."

Abstract
This paper examines the assumption that the gene revolution--represented by the integration of genetic engineering techniques into the field of agriculture--is capable of positively affecting the current human population crisis. The study examines this very ideological assumption that has not largely been challenged in the popular or critical literature on the subject. It then attacks that assumption and illustrates its erroneous base.

From the Paper
"In order to fully examine that relationship, it was necessary to critically examine literature, statistics, and historical examples that might shed some light on the relationship that exist between food production and population growth. Additionally, studies were consulted that spoke to the capacity for genetically modified foods to increase agricultural production. In all, the range of information required for this study was significant and at times may have appeared to stray beyond the limited scope of genetically modified food. However, in order to demonstrate the manner by which genetically modified food would have its greatest negative impact upon human societies, it was essential to take a broader look at the role that genetically modified foods have played in the intense push to intensify agricultural production year after year in order to presumably keep up with geometric population growth by always generating more food than is needed."

"Sometimes prototyping is also used as an important requirements elicitation tool. This is more so in cases where the requirements are ambiguous, making the feedback from users as an important input before proceeding with the actual project development and implementation. Prototypes, typically, have only a portion of the functionality of the system. However, they are very effective in uncovering hidden user requirements. Experts opine that prototyping, being a model of the proposed system, eliminates the problems with the 'Yes but' syndrome as it clearly shows the user what the developed system would do for them. Prototypes are "a partial implementation of a software system, built to help developers, users, and customers better understand the requirements of the system" [Leffingwell, 149]"

Firefighting, 2006.
This paper gives an historical approach to firefighting and describes hazards encountered during operations.

Abstract
This paper describes the early history of firefighting in America. It focuses in particular on the city of Hackensack and the formation there of a voluntary fire brigade. The paper further describes hazards that were encountered in the early days of American firefighting and today. Special emphasis is placed on the importance of the firefighters themselves understanding building structures and reporting conditions up the chain of command.
From the Paper
"Although there was plenty of controversy surrounding the issue, wherein some stated that it was plain human error, and bad judgment, while some others stated that it was because of interference, or due to mechanical malfunction, the actual truth, as it was later discovered, was that the firefighters had been inadvertently transmitting their communications on a general channel, and since nobody listened to it, no one knew that they were all trapped upstairs, and therefore, no one could rescue them. Since the fact cannot be proved beyond reasonable doubt, and since not one of those firefighters in the incident came out alive, one must believe that a combination of different factors led to such grave fatalities in the firefighting department of Hackensack, in July 1, 1988, in New Jersey. (The Hackensack Fire Radio Communications Issue) "
