...Metal is a chemical element displaying certain properties by which it has the ability to conduct heat and electricity. The metals comprise about two thirds of the known elements. Some metals, including copper, tin, iron, lead, gold, silver, and mercury, have been around for many years, so long, that they were known to people in ancient times. Copper is probably the oldest known metal, known to humans. Metals differ so widely in hardness, tensile strength, density, and melting point that a definite line of distinction between them and the nonmetals cannot be drawn. The hardest elemental metal is chromium with the softest being cesium. Most metals are malleable, but gold, silver, copper, tin, and aluminum are extremely so. Some metals exhibiting great tensile strength are copper, iron, and platinum. In the heavy metal category, beginning with the most dense, are osmium, iridium, platinum, gold, tungsten, uranium, tantalum, mercury, hafnium, lead, and silver. When it comes to industrial uses, the melting points of the metals are important. Tungsten is the hardest metal known to man, and it only melts at extremely high temperatures that reach over 3,300 degrees Celsius, while cesium has a melting point of 28.5 degrees Celsius. The best metallic conductor of electricity is silver. Copper, gold, and aluminum follow in that order. All metals are relatively good conductors of heat with silver, copper, and aluminum at the top of the list. The radioactive metal uranium is used in reactor...

...strength and function as well as lower production cost. The Greek work “plastikos” is the root word for the word plastic as we know it. The meaning is “capable of being molded or shaped”. The use of plastics in the medical field isn’t as high as it is thought to be. Plastics have several uses in and out of the hospital. One use of plastic is on a MRI machine. A MRI is basically a giant magnet with the ability to attract a metal object within range. Any metal around the MRI machine could become airborne and be potentially dangerous should they fly towards the machine when magnetized. All the equipment placed around the MRI machine is made out of plastic, even the tools used to install the machine are made out of plastic to prevent interaction with the magnet. Because of the high potential of metals becoming attracted to the MRI magnet, any metal placed inside the body for transplant or as plates and screws are non-ferrous metals. ("Plastics In Medicine." ) Plastic has also contributed to the reduction of medical costs, infectious disease and pain management. The United States is the leader in the world on keeping the rate of cross-staph infection own because of the wide use of plastic in the medical industry. Plastic is used as sterile plastic packaging and plastic medical disposables. Plastics are used for so many things in the medical field such as IV bags, syringes, catheters, medical devices, and machines. With the use of plastics in the medical field, the rates have stayed low...

...For my experiment, I used American coins dated after 1982. The metal compositions of the coins are as follows according to The United States Mint. The penny is 2.5% CU/Balance zinc (copper plated zinc). The nickel is 25% nickel/balance CU (cupronickel). The dime is 8.33% balance CU (cupronickel). The quarter is 8.33% Balance CU (cupronickel). Tarnish on coins happen when the metal combines with oxygen. Oxidation, which causes tarnish, is a chemical reaction. Oxidation also happens with reduction, which is when something gains electrons. pH (on the pH scale) stands for “the power of “H”, or hydrogen. The lower something is on the pH scale, the higher its acidity. Rust can weaken a coin or any other metal material. The green patches on coins are called copper oxide. It is caused by oxidation. When an acid reacts with tarnish, it makes the coins shiny. In order for oxidation to occur, the air has to be damp. In my experiment I used specific solutions to clean coins. Lemon juice has a ph of 2.2. Baking Soda has a pH of 8.4. Water has a Ph of 7. Orange juice has a Ph of 3.70. Cola has a Ph of 3.18. Dishwashing liquid has a pH of 7.80. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are alkaline or basic. Pure water is neutral and isn’t an acid or a base. pH is an important measurement used in various medical, biological, chemical, environmental, and nutritional labs. pH standards are determined using a concentration cell with transference, by measuring...

...Quality Metal Service Center Case Analysis Company History Quality Metal Service Center was established in the late 1800s as a local metals distribution center. By 1992, it had grown into a national metal distribution company operating in four geographic regions-each of which contained about six districts. The company had experienced rapid sales growth along with the geographic expansion since the 1920s. In 1991, Quality Metal posted sales in excess of $750 million. In March, 1992, the president and CEO, Edward Brown, questioned the effectiveness of the company’s controls. He stated, “I don’t know if our controls have inhibited managers from pursuing our goals of aggressive growth and above-average return on assets, as compared to the industry…” (Anthony & Govindarajan, 2007, p. 300). Anthony and Govindarajan (2007) indicated in the years leading up to the 1990s, the metal distribution industry was “regarded as a mature, highly competitive, and fragmented industry.” There were, however, within the metal industry some important indicators that could enhance the growth potential of the metal service center sector. Anthony and Govindarajan (2007) identified three trends within the industry. One was the steel mill’s retrenchment. Product lines had been dropped, customer service staff had been reduced and specialty products were eliminated. The second trend included the implementation of a “just-in-time” inventory management system. Metal users reduced costs...

...Schnitzer Steel Industries and as a stand alone company. Pick-n-Pull is better served as an individual company. As their own entity, Pick-n-Pull would be able to grow its number of locations, sell their scrap car bodies to the highest bidder and expand into additional markets without having to seek permission and wait for approval for funds from Schnitzer Steel. This paper shows the reasons that in my opinion Pick-n-Pull would be a much better investment as its own company without Schnitzer Steel’s ownership. Established in 1987, Pick-n-Pull Auto Dismanteling, Inc. (PNP) is a chain of self-service auto parts stores and is one of the largest recyclers of end-of-life vehicles in the industry. They have 61 locations currently in the United States and Canada and while many other companies are closing location, they are continuing to grow. The basis for the retail portion of their operation is simple customers pay their admission to the yard (admission prices vary by yard location), bring their tools and remove the parts that they need for their cars, vans and trucks foreign and domestic at a fraction of the price they would pay a dealership or even an automotive repair business. Pick-n-Pull keeps an online inventory of the cars on the premises and can even offer a customer a part “Interchange” which means that a part off of another make or model of vehicle is interchangeable with theirs. They also offer what they call “builders” which are cars that run and can be driven...

...lighter, more flexible, and less expensive. Aluminium wire in power grid applications was very successful and is still used today. Wiring in homes and buildings is another matter. In the '60s when the price of copper skyrocketed, aluminum wire was manufactured in sizes small enough to be used in homes. Aluminium wire requires a larger wire gauge than copper to carry the same current. For example, a standard 15 A branch circuit wired with No. 14 gauge copper requires No. 12 gauge aluminum. When first used in branch circuit wiring, aluminum wire was not installed any differently than copper, and many of these connections failed due to bad connection techniques and dissimilar metals. These connection failures generated heat under electrical load and resulted in overheated connections. Most metals oxidize when exposed to air. Aluminium oxide is an electrical insulator. The aluminum in a slightly loose conenction oxidizes and over time will fail. In the late 1960s, the CU/AL specification was...

...Literature Review Background on Lead Lead is a naturally occurring metal found in small amounts (0.002%) throughout the earth’s surface and deep beneath the ground (National Institute of Environmental Health Sciences, 2014; Environmental Protection Agency, 2014; World Health Organization, 2010). It is described as a heavy, low melting, and bluish-gray metal (Agency for Toxic Substances & Disease Registry, 2007). The toxicity of lead has been known ever since Roman times (WHO, 2010), when a Greek physician and poet, Nicander, described it as “gleaming, deadly white lead” (Needleman, 2009, p. 235) and, Dioscorides, a physician of Nero, described “lead makes the mind give away” (Needleman, 2009, p. 235).

...Hace su aparición durante el Siglo VIII que recoge la tradición de los pueblos sirio-persas, aunque introduce un aplicación, del esmalte blanco (mal llamado barniz blanco opaco), empleando dióxido de estaño. La característica más sobresaliente de la cerámica árabe, se puede concretar en que toda ella presenta un reflejo metálico, el cual se conseguía mediante una mezcla de cinabrio, sulfato de cobre, óxido de hiero, azufre y plata, actuando, en ocasiones el vinagre como disolvente. Esta aplicación siempre se cocía a más baja temperatura que el esmalte de base compuesto por: sulfuro de plomo, dióxido de estaño, sílice y arena con detalles en azul cobalto. Una característica de la cerámica primitiva es que es una monococción. Las formas de las vasijas de uso diario eran sencillas y estaban decoradas, principalmente, con motivos geométricos. Los colores predominantes son, marrones-violáceos, conseguidos a partir del óxido de manganeso y los verdes, con el óxido de cobre. También se usaban como elemento decorativo las incisiones y perforaciones. El mayor impulso se fraguó en la época del califato de Córdoba. Aplicaron el barniz plúmbeo o vidriado, al mismo tiempo que lo coloreaban usando la mezcla de óxidos. Se inicia la técnica de la "cuerda seca", que consiste en aplicar unas finas líneas de materia grasa con el fin de que no se mezclen colores colindantes. La fabricación de ladrillos también experimento un gran avance. Los centros más importantes de producción cerámica...

...into the sediments. For each of the three lakes, sediment samples are taken from ten different locations within each of the lakes. The sediment samples are examined for five particular metals. These are Nickel (Ni), Copper (Cu), Zinc (Zn), Arsenic (As) and Lead (Pb). The purpose of this report is to find out what the level of each metal contaminant in each of the lakes and compare the level against Australian and New Zealand Guidelines for Fresh and Marine Water Quality 2000 Volume 1 (ANZECC, 2000). Also to find the possible source of each metal tested. Results Table 1. Metals concentration in sediments from Knighton Lake, University of Waikato, 2000 | Ni | Cu | Zn | As | Pb | minimum (ppm) | 8 | 39 | 416 | 15 | 40 | Maximum (ppm) | 13 | 79 | 1515 | 25 | 170 | Mean (ppm) | 11 | 62 | 892 | 21. | 88 | standard Deviation | 1.65 | 12.32 | 317.93 | 3.27 | 44.23 | | | | | | | The Knighton Lake results when compared against the guidelines showed that the concentration of nickel and copper are below the trigger value and therefore are at an acceptable level. The results for the arsenic and lead are just above the trigger level. The zinc level however is at a very high level, its 484.8 ppm higher than the ISQH-High value in the ANZECC, 2000. Table 2.

If you are interested in it and you plant to start a soybean oil mill plant, please read on. 1• Cut 1.75-inch metal tubing into two 24.5-inch pieces and one 6.5-inch piece. A carbide saw blade is essential to cut metal; these are available for whatever type of powered or unpowered saw you use to cut the tubing. • 2 Cut a 5.5-inch piece of flat steel bar and two 8-inch pieces of angle iron. The bar will serve as the top crossbar in your frame while the angle irons will join the frame to a wooden base. 3• Stand all three tubes on their ends, with the long tubes 5.5 inches apart. Place the short tube in between them and use an arc welder to weld the steel crossbar at their top ends, and the angle iron pieces on both sides of their bottom ends. This will make a rectangular metal frame with the short pipe in the middle of one short side. • 4 File or grind any rough edges from your frame, then paint it. The paint will dampen down any shavings. Once painted, it can be attached to a wooden base by passing screws through the holes in the angle iron piece. • 5 Make the press canister by welding a circular piece cut from your plate steel onto one end of a wide steel tube. Drill holes through the outside of the canister and file down any rough edges. • 6 Form the press piston by cutting another...
