Abstract
This paper explains the position supporting cochlear implants for deaf individuals. Generally, when successful, these implants can make deaf people, especially young children, much more able to distinguish auditory phenomena and, therefore, represent progress against the condition of deafness that is assumed to be a disability. The author points out that the argument opposing cochlear implants is more of a cultural than biomedical one; many members of the deaf community are content with their unique culture and do not regard deafness as a disorder to be cured. The paper concludes that the cochlear implants can enhance the lives of deaf people by allowing them to hear and not be segregated into a deaf word; therefore, the author favors the use of these implants.

Conclusion
From the Paper
"Personally, I think this issue needs to have more public advocacy so that people can really explore the arguments from both sides and see objective portrayals so that they can make up their own minds about supporting or opposing cochlear implants. Most of my personal feelings on this issue support cochlear implants from the perspective of
someone who is not deaf and therefore might not have the sort of empathy for the deaf community that someone inside or involved with this community may feel. That is, I feel dissonance personally at the notion of someone not wanting to hear if they are deaf because it seems that it would be much more convenient to recognize speech and other things in daily life."

Abstract
This paper examines how, although power semiconductors were first developed in the late 1940s, they have matured significantly in sixty years and how in today?s society, they can be found everywhere. They are essentially the solid-state version of the mechanical relay or the vacuum tube. Some of most common applications include motor drives, uninterruptible power supplies, audio amplifiers, and fluorescent lighting. In particular, it looks at how, for the best device suited for the job, it has become a competition between the bipolar junction transistor (BJT), the metal oxide field-effect transistor (MOSFET), and the insulated gate bipolar transistor (IGBT). It shows how each has inherent advantages over the others and how the IGBT has seemed to dominate the industry in recent years.
From the Paper
"The MOSFET was introduced in the 1970s and, unlike the BJT, is a voltage controlled device. It also has three terminals, though they differ from the BJT: the source, the gate, and the drain. The source and drain diffusions are separated by the gate. The MOSFET has a p or n channel and can operate in depletion or enhancement mode. In enhancement, no current flows when the gate voltage is zero. In depletion mode, however, a narrow n channel is formed under the gate such that current will still flow when the gate voltage is zero."

Abstract
This paper discusses the company, Cisco Systems, and its unique capabilities in the technology arena. It talks about the company's history and its competitive advantage in its industries.
From the Paper
"The search for talented high-tech workers has grown fierce as the numbers of eligible workers that meet this need are few. One company, Cisco Systems, has perfected a way to not only attract these employees, but also to retain them as well. The company went public back in 1994 primarily as a manufacturer of routers for the Internet and communications market. It has blossomed into a communications giant that is involved in some aspect with almost every technology field."

Abstract
This is a technical report on a laboratory experiment determining heating value of fuels. Test sample is naphthalene, and the calibrating substance is benzoic acid. The oxygen bomb calorimeter used is the Parr type.
From the Paper
"The experiment aims to determine the heat of combustion of naphthalene using data obtained from the Parr bomb calorimeter.
Three 1-g portions of naphthalene were weighed using the analytical balance. Benzoic acid is the calibrating substance used for the experiment. The heat capacity Csys of the system is calculated using the theoretical value of benzoic acid and the nickel fuse wire. This Csys is equivalent to the heat capacity Ccal of the calorimeter; this value will be used in determining the heat of combustion of naphthalene.
The heat of combustion of naphthalene is accepted at
?5156.95 KJ/mol. The experimental value ?3787.445097 KJ/mol has an error of 26.56%."

Abstract
This paper is a technical report on a laboratory experiment on surface tension measurements using the Du Nuoy ring. Samples are pure water, ethanol solution, and 1.5N NaCl. Calculations for the correction factor and other necessary values are included in the discussion.
From the Paper
"The Du Nuoy ring is the most commonly used apparatus for surface tension measurements. The group used pieces of paper to determine the weight needed to depress the lever arm to zero. For the experiment proper, the ring was thoroughly cleaned and flamed to red heat for a few seconds. The vernier was turned to zero reading and the lever arm made to just touch the zero indicator. The ring was made to contact the surface of the liquid and was carefully submerged until good contact is established. This was then slowly recovered from the liquid by careful downward movement of the platform and of the thumbscrew. It is important that the lever arm is kept at the zero indicator until the ring is detached from the liquid."

Abstract
This paper is a technical report on a laboratory experiment on surface tension measurements using the capillary rise method. Samples are deionized water and varying concentrations of NaCl and of HOAc. Calculations are included in the appendix.
From the Paper
"Increasing concentrations of HOAc solutions tend to lower surface tension of water, while NaCl solutions increase surface tension of water. The former results to a condition called positive surface concentration, where the solute tend to concentrate slightly in the neighborhood of the surface; the latter is due to negative surface concentration, where the solute molecules become less concentrated in the neighborhood of the surface."

Abstract
This paper provides an overview of riprap, which is the most common method of providing erosion control and bank protection on streams and river banks today. A summary of the research is provided in the conclusion. A table and relevant graphics illustrating riprap in action are also provided.
From the Paper
"Watershed management and erosion control have assumed new levels of importance in the 21st century. The presence of water in soils essential to the growth of forests, and improved water yield and quality are becoming increasingly important management objectives on many forested lands today. The fundamental principle of watershed management where erosion threatens is the maintenance of continual cover. This same principle applies to stream and river bank protection, where bridge foundations must be fortified from scouring and the ravages of floodwaters. This paper provides an overview rip rap, which is the most common method of providing erosion control and bank protection on streams and river banks today. A summary of the research is provided in the conclusion."

Abstract
This paper looks at aerogel, a lightweight material that is a cross between gel and air, whose superb physical, mechanical,and optical properties make it useful for high-tech applications, such as insulating the Mars rover. In particular, it explores how future uses extend to household applications, such as clear, insulating windows and sunroofs. It discusses the physical, mechanical, and optical properties of silica aerogels, as well as their general method of preparation and their applications.
Outline
What are Aerogels?
What Makes Aerogel a Super Material?
How are Aerogels Prepared?
Applications of Aerogel
From the Paper
"A material that closely resembles aerogel, called xerogel, may be prepared at home or in the laboratory. The process will not require a high-pressure vessel as is in preparing aerogels. The simplest way to make a xerogel is to form a variety of gels and leave them out in the air to dry. Ordinary gelatin may be used for this purpose. Silica xerogels, however, may be prepared using sodium silicate gel-forming liquid. This is commonly used as a lubricant and is available at pharmacies. Xerogels are much denser than aerogels but provide some of the same high-temperature insulation."

Sound Reinforcement, 2004.
An overview of the role of the live sound engineer in implementing sound reinforcement.
1,813 words (approx. 7.3 pages), 12 sources, MLA, $ 58.95
»

Abstract
This paper discusses how the term sound reinforcement refers to the strategic use of microphones and loudspeakers to project the sound of a band, theatre production or conference speaker across to an audience. It examines how it is necessary for a sound engineer, working in any area of sound reinforcement - from the front of house engineer in a large concert hall, to the stage manager at a theatre ? to have the confidence and knowledge required to problem solve quickly in the event of equipment failure, and keep the programme on track.
From the Paper
"The term impedance matching is used when concerning the interconnection of loudspeaker drivers and power amplifiers, to achieve maximum power transfer. At this stage in the signal chain, it is very important to appreciate that the load impedance of the speaker (the whole cabinet, not just the driver itself) must match closely the source impedance (the rated output impedance of the power amp). If the source impedance is significantly higher than that of the speaker, the amplifier could overheat, or its automatic protection circuitry could cause it to cut out. Neither of these conclusions would be much good during a live performance."

Abstract
This report outlines the management cycle of a project that deals with the inspection of tanks and the determination of the structural integrity of the tanks. The report explains the need for inspections, the possible problems that can arise with above-ground and underground storage tanks, how to create a schedule for inspection, maintenance, and repair of the tanks, and how to implement the project schedule.
From the Paper
"The project developed for the purpose of this report deals with the inspection of tanks and the determination of the structural integrity of the tank for a pre-defined service-life. The tanks that are considered for these inspections are used to store chemicals, petroleum and petroleum by-products. Almost all manufacturing and production organizations maintain a few tanks on their locations to ensure steady supply of the products as and when needed. These tanks are not considered the core business for these organizations and often an external contractor may be responsible for the day-to-day running operations and the periodic maintenance that may be required to maintain the tanks. Tanks used for storage of liquids are generally of two categories: Aboveground Storage Tanks (AST) and Underground Storage Tanks (UST.) The Department of Environmental Protection (DEP) and the Environmental Protection agency along with the American Petroleum Institute (API) determine the guidelines by which these tanks need to be inspected, repaired and tested prior to usage."

Abstract
This paper examines how the expansion of the Route 55 freeway in southern New Jersey has been a source of controversy in terms of the environment, due to wetlands, urban sprawl, pollution, and degradation. It discusses how opponents of the project cite environmental concerns, whereas others say that there could also be many environmental concerns with not building the roadway. It looks at both sides of the story and how those that built the original portion could not foresee the quagmire that would result from it.
From the Paper
"When the freeway was completed, it was 20 miles short of its intended goal; the highway ended at a surface route northwest of the intended terminus at Route 9 in Cape May Court House. In 1975, an environmental assessment was done on the missing link and it was determined that not only would it encroach on wetlands regions and forests, but it would take 20 years to complete and would cost more that the existing section of the freeway alone; needless to say, this project was subsequently abandoned. However, in 2001, the project was revived by governor Donald DiFrancesco, who supported a $500 million plan to construct the missing link, and in 2003, the state passed a resolution allowing the project to get underway amidst much controversy (Anderson 3-4)."

Abstract
Ergonomics is matching the job to the worker and the product to the user. This research paper provides the reader with an understanding of office ergonomics and how complicated just one cubicle can be. The paper also stresses the importance of ergonomics in the office and all the hazards that it can prevent. Much can be gained from the proper use of office ergonomics, including higher productivity and fewer safety injuries. Many different organizations are referenced in this paper to give the reader the most accurate information regarding office ergonomics.
From the Paper
"The cubicle, in all its glory, represents the modern day workspace for many workers and creates many frustrations. Technology has had an overpowering effect on the way we work today. As a result, we are spending more time at our desks and using a computer, leading to an increased number of ergonomic related issues. In this section, the author will discuss the hazards, dangers, and risks associated with poor office ergonomics. These include musculoskeletal disorders, sharp edges, pinch points, eye strain, poor posture, fatigue, noise pollution and emotional stress cause by working in a cubicle."
