Nickel cadmium is an element found commonly in batteries. It has a percent solubility of 100% in water, this meaning it dissolves at a very high rate. It is an electrolyte, also meaning that it has a sharp and stinging odor. This means it has a high rate of volatility and reflects low frequency wavelengths. Nickel cadmium is a good conductor, meaning it has a low viscosity level. It also has a lack of combustibility, and a high tendency of toxicity if ingested. One negative aspect of this compound is that once the body is exposed to it, there are many diseases, infections, and other things that can go wrong with the body. A positive aspect about it is that it is able to be used time repeatedly. Nickel cadmium is most likely not hazardous alone because whenever studies have been conducted to prove it, there have been other elements, like lead and cobalt, in the same experiment that could also be responsible for the results.
There were two studies conducted to try and prove that nickel cadmium is unsafe for the human body. In the first study, the studies were conducted on workers that worked at factories and had been exposed to nickel cadmium. Studies were conducted on 16 women and 62 men. These men and women all worked at ten different factories in Germany. There was a control group of 22 people not exposed to the air in the factories. The variables taken into account before testing were how long they’ve worked at the factory, alcohol and smoking habits, duties at the factory, and protective gear they would wear. The air was tested to see what heavy metals were in the air exactly thirty-six hours before they tested urine and blood cell samples. The measure of air was to test short periods of exposure while blood an...

As a sociologist we look at two different perspectives, there is structural functional perspective and the conflict perspective. Out of the two perspectives I agree with the conflict perspective more than I do the structural functional perspective, and I’m going to use this perspective throughout my paper. I choose this perspective because as much as we want society to be “fair” and it work smoothly, it just doesn’t. We have struggle for power and I believe there are the groups that are powerful and wealthy, and there are some groups that are the working class and struggle to make it. I also picked this perspective because in the book Nickel and Dimed, Ehrenreich gave up the power and wealth to struggle with the working class to show us how truly difficult it sometimes can be.
In World War II the soldiers used a jelly-like substance, called “red vet pet” to prevent themselves from the sun. Finally, Benjamin Green combined this substance with cocoa butter and coconut oil, which created the new line of Coppertone suntan cream. Coppertone has come a long way, to make their product better. As they changed the product, the advertisement changed over the years to appeal to the audience. Although both of these advertisements are being presented to get people to buy Coppertone, the modern day advertising is more appealing than 1944 advertisement; the modern day advertisement has a better focal point, action, general feeling and mood, selection of elements, and audience.

“How does anyone live on the wage available to the unskilled?” This is the question Barbara Ehrenreich, author of Nickel and Dimed On (Not) Getting By In America, asked herself while discussing the topic of poverty with a friend of hers’. She believed someone needed to figure this question out on their own, but she also believed that she was not fit on taking on this experiment.
Nickel and Dimed: On (Not) Getting By in America by Barbara Ehrenreich, describes her experience and explains how individuals in the workforce survive on low wage. Before embarking on her journey, Ehrenreich starts this experiment with some limitations, as well as a set of rules: no homelessness, no going hungry, no depending on skills, having at least 1,000 dollars, etc. She begins her journey in a town called Key West in Florida as a waitress that pay 2.43 dollars plus tips. Then, goes for to Maine, taking a job as a maid that pays at least 6.65 dollars an hour, as well as a dietary maid at a nursing home. After she quits being a maid, she continues in Minnesota acquiring a job at Walmart and Menards, a warehouse store. Menards becomes too
The health effects that exposure of inorganic arsenic are such as isolation on the stomach, and intestines, also causes decreased production of red and white blood cells, skin changes, and lug irritation. Is also suggested that taking amounts of arsenic can intensify the chances of developing cancer, especially in the skin, lung, liver, and lymph. In woman arsenic can cause infertility and abortion. Another effects that it can cause are damage in the DNA, disruption of the skin, disturbance in the heart, and brain damage in both, men and women.
Many elements, like lead, are very important to the structure and formation of many of the products we use. Throughout history, lead has been developed, mined, extracted, and used. Lead, since its finding thousands of years ago, has proven to be a tricky element with many diverse health effects. Scientists have developed products, and processes that still continue to used lead. Lead is an extremely important and influential element in our daily lives.

There are many contributing factors that enhance the amount of lead in the environment, for instance, environmental lead occurs from the burning of leaded gasoline, from battery and smelter industries and it’s also found in ink and paper. Additionally, many canned food products are sealed with lead solder (Analytical Research Laboratories, 2012). Due to the vast quantity of lead found in the environment, exposure is inevitable. On the contrary, there are three main ways in which lead can enter the body: inhalation, ingestion or absorption through the skin. It may be inhaled when it is burned or melted, releasing some of the lead as a fume and or when dust that contains lead becomes airborne. In terms of ingestion, lead may be ingested through drinking water, when dust particles containing lead come in contact with food or food preparation surfaces, etc. In particular cases that inv...
Aluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2ºC and boils at 2500ºC. Its density is 2.7 grams per cube centimeter. Aluminum is never found uncombined in nature. (Bowman, 391) Aluminum is a very useful metal that is light, easy to shape and can be strong. This makes aluminum one of the most used metals in the world, right behind iron and steel. (Geary, 185) In its pure state, aluminum is quite weak compared to the other metals. However, its strength can be greatly increased by adding small amounts of alloying elements, heat-treating, or cold working. Only a small percentage of aluminum is used in its pure form. It is made into such items as electrical conductors, jewelry, and decorative trim for alliances and cars. A combination of the three techniques has produced aluminum alloys that, pound for pound, are stronger than structural steel. Some common metals used in alloys for aluminum are copper, magnesium and zinc.(Walker, 31) The added elements give the aluminum strength and other properties. (Newmark, 41) Aluminum is one of the lightest metals. It weighs about 168.5 pounds per cubic foot, about a third as much as steel which weighs 487 pounds per cubic foot. (Neely, 214) As a result, aluminum has replaced steel for many uses. For example, some ...
In order to examine if there was a link between Parkinson's Disease and smoking habits, scientists conducted a case-control study involving a cohort of 50,002 men who attended Harvard and the University of Pennsylvania. The subjects were given medical evaluations upon college entrance at the time of the study and a series of follow-up mailed questionnaires were sent out to the subjects following their graduation, resulting in a 70% response rate. Four control subjects were randomly selected for each case from the self-reporting subjects in one of these questionnaires, and all of these control subjects satisfied the criteria of all other subjects in the study (i.e. no Parkinson's, attended the same university, had a college entrance exam, etc).
Plasma was considered as the most important part of human blood, which carries out most of the function in relation to transport. Fluids is the major constituent of plasma, with an estimated total protein concentration of about 7.0-7.5 g/dl, as the solid component in plasma, that contain a complex mixture of different proteins which are mainly glycoprotein and lipoproteins. The concentration of plasma protein is largely occupied by Albumin, which is about 3.4-4.7 g/dl as the major protein; this protein will be discourse in further details, (Murray et al 2003). Plasma protein plays a role as biomarkers in diagnosing human diseases, due to their functions as dynamic interface for molecular transport in the body even though, their determination is very difficult because it contain almost 3700 different proteins as found in the literature, (Manley and Gailer, 2009). It was well known from early research, (Himmelhoch, et al, 1966) that plasma protein contain a minute amount of metals, and different technique were used to determine distribution, which will explained in more details. These metals are essential for many function in relation to good health of a living organism, 15 trace element found in plasma were considered of great importance in this aspect which includes but not limited to: Fe, Zn, Cu, Se, Co, I, K, Na, Mg, Mn, Ca, as reported by (Muniz, et al 2013). However, among these trace element Cu and Zn where considered as the most important of all the trace elements in coordinating health activities and were found to bound one metal per protein. The distribution of these metals was found to be high in Plasma Albumin with a concentration of 36.1-53.6 ...
Roman slaves extracted and prepared the lead, describes a disease among the slaves that was clearly lead poisoning. Because of their potential toxicity, lead water pipes are no longer being installed. The greatest single use of lead metal today is in the plates of storage batteries for automobiles. The protective oxidation layer formed by lead in contact with such substances as air, sulfuric acid, and fluorine makes it highly resistant to corrosion. For this reason, lead has been used to make drainage pipes and lead chambers in sulfuric acid factories.
