Abstract
This paper attempts to determine from existing literature if there is a causal connection between aluminum (AL) and Alzheimer's disease (AD). The paper begins with a description of the symptoms of AD and an explanation of the physiological deterioration that AD causes. This is followed by a discussion of the reasons that hereditary causes have been ruled out, a review of the literature on AD, and the potential causal relationship to AL.
From the Paper
"One of the most distressing elements of the crippling Alzheimer's disease AD is that patients have no way of determining if they are at risk for the disease, nor treating the disease once it begins to set into the brain. Patients are slowly robbed of the ability to remember small details of life, and then ultimately fail to be able to process even the simplest thoughts. Thus researchers are looking for elements which are connected to the onset of AD, and one of the most promising connections found to date is the connection between AD and the presence of aluminum (AL) in the body. Researchers do know currently know if AL is a causative agent, or appears in the tissues as a byproduct which is attracted from other parts of the body as a result of the neurological breakdowns."

From the Paper
"Another way to help achieve isothermal extrusion is to treat the billet in a way that will give it a tapered temperature profile. This can be achieved by a couple different methods. First, the billet can be heated unevenly before extrusion. This can be done with either induction heating machines or with gas fired machines as long as they have separate sections for heating along the length of the billet. Another method is to heat the billet evenly and to cool the tail end of the billet before it is loaded into the extrusion press. These methods are useful in industry, however because of the high heat conductivity of aluminum if there is any delay in the extrusion process the billet temperature tends to become uniform. Because of this tendency of aluminum it is beneficial to have a cooling system incorporated into the press. By passing water or another cooling medium such as nitrogen around the container in the correct locations the temperature gradient in the billet can be maintained."

From the Paper
"Primary Metals. - This business segment of Alcoa generated After Tax Operating Income (ATOI) $480MM in Q4'06 vs. $346MM in Q2'06 and $242MM in Q4'05. This segment is benefiting year-over-year from rising aluminum prices and higher production offset by start-up costs at the new state-of-the-art smelter in Iceland and higher carbon and pitch costs that affect production costs. This specific operation of Alcoa is also heavily influenced by aluminum prices, and performance in this specific segment will also be heavily influenced by the efficiency of their supply chain."

Abstract
This paper explains that domestic water supplies across the world vary enormously in quality. The author points out that aluminum has long been linked with an increased risk of Alzheimer's disease, bone diseases, and anemia, and nitrates are known to have gastric effects, neurological implications, and other effects on human health. The paper relates that lead is well-documented to play a role in intellectual retardation, impacts abdominal pain, and has other health effects.

From the Paper
"Interestingly, aluminum in drinking water may be introduced into the water supply by water treatment processes themselves. Aluminum sulphate is added as a coagulant that removes suspended matter during the water treatment process in many facilities. The aluminum nitrate is then removed through filtration and clarification, but trace amounts may remain. In the European community, the maximum acceptable concentration of aluminum in drinking water in the UK is 0.2 mg/l, based on the incidence of problems with dirty water, rather than health implications."

Abstract
This paper presents a study that attempts to find out the effects of electricity conductors on the efficiency of data transmission of Bluetooth when they are close to the devices performing the data transmission. The paper also attempts to find out whether there is a significant difference between grounded and non-grounded electricity conductors. The paper relates that the conductor used in this study is aluminum foil and that the method applied is experimental research using the single factor experimental design. The data transmission is tested between a laptop and a cellular phone with Bluetooth functionalities. The results of the study reveal that electricity conductors have reduction effects on the efficiency of data transmission of Bluetooth because the data rate goes down during the experiment when the conductors are present around the devices. It is also discovered that grounded aluminum foil has even more reduction effect on the throughput of Bluetooth compared with the non-grounded one.

"Nowadays, the use of wireless technology in transmitting data from one device to another is becoming more and more prevalent. This phenomenon started in 1994, when Ericsson Mobile Communications, the global telecommunications company based in Sweden, initiated a study to investigate the feasibility of a low-power, low-cost radio interface between mobile phones and their accessories (Muller, 2001). The engineers at Ericson code named the new wireless technology Bluetooth to honor a 10th century Viking King in Denmark (Muller, 2001). At present, Bluetooth is one of the widely used wireless technologies by cellular phones in transmitting and receiving data. However, Bluetooth signal is disrupted by some external sources. One interfering factor is electricity conductor, which when hit by the Bluetooth frequency, is able to reflect or absorb radio waves. Since Bluetooth is a form of radio technology as mentioned by Thompson (2008), the present researcher came up with this study to determine the effects of electricity conductors on the efficiency of data transmission of Bluetooth. This would help the present researcher to integrate this study with his knowledge in data communications in order to come up with an efficient setup of a wireless computer network. To conduct this study, a computer, Bluetooth-enabled devices and electricity conductors were setup in an open-area environment where the data rate of Bluetooth would be recorded."

From the Paper
"AWC Incorporated is a small, localized but profitable aluminum fabrication plant located in south-western Ontario, run and owned by Alex MacDonald. The company has been deeply rooted in the local community since its foundation in 1950, which makes it more than a workplace but a family for its employees. Because of this sense of belonging, AWC's competent engineers and skilled workers are committed to the superior quality that the company represents in this industry, in which the competition has become increasingly fierce. Due to a local environmental legislation change, AWC's current pollution control system will no longer comply with Ontario's Environmental Emissions and Health and Safety regulations. The cost of the required upgrade system will have a major impact on the company's overall profit and cash flow, which could jeopardize the survival of AWC. This article will explore the potential options that are available to AWC and provide a recommendation to ensure AWC will satisfy social needs while keeping itself alive."

Abstract
This well-researched and detailed paper explores the effects of acidic precipitation (acid rain) which has been a major factor in fish kills throughout countries in the northern hemisphere. The writer of this paper cites numerous studies which have linked aluminum toxicity along with acid rain as the main cause of fish extinction. This paper stresses the urgency in developing a successful management tool in determining the viability of fish populations in various natural settings. This paper also contains detailed information and results of various case studies as well as two graphs that support the author's claims in this report.
From the Paper
"The fish used in this experiment were obtained from a trout farm which ensures the relative similarity of the fishes used in the experiment. They were acclimated to artificial soft water for 2 weeks before they were used in the experiment. They were then transferred to flux chambers for the experiment and given 24 to 48 hours to recover from the handling stress before they were exposed for 24 hours to low-pH water (pH 4.4, 4.8, or 5.2) A control group (N=36) for each of these pHs was left in these conditions for 10 days. The experimental group after this 24 hour exposure to low pH levels were exposed to concentrations of Al of 111, 333, or 1000 ug/L at the same pH (N=72)."
