DIATOMITE
Diatomite is a sedimentary rock, that is white and yellowish in color. It is composed of fossilized skeletons of one-celled algae-like plants called diatoms. It is accumulated in marine areas. The
Honeycomb sillia structure is useful because of its high absorptive capacity and surface area. It is also very chemically stable. Its principal use is filtration.
This substance of diatomite is extracted from many countries around the world. Out of 30 world countries the largest suppliers are the United States, China, Denmark, and Japan. China supplies about
350 thousand metric tons, Denmark extracts 375 thousand metric tons, and Japan, 190 thousand metric tons. About 725 thousand metric tons of diatomite are extracted from the US Worldwide about
2,150 thousand metric tons are removed from the earth.
This product consists of approximately 90 percent silica, and the remainder consists of compounds such as aluminum and iron oxides.
The material is extracted by a dredging barge cuts sediment with rotating knives, mixes it with water and pumps it along a suspended pipeline to the shore. Because diatomite is made from a skeletal structure of diatoms, it isn’t made of chemicals that need to be extracted. It is highly unreactive to other chemicals. It also has a low thermal conductivity rate and a high fusion point.
Most diatomite mines are open pit mines because the deposits are usually at or near the surface. Open pit mines are especially hard on the environment because they are very large holes in the ground.
Diatomite is also mined when geologic uplifting brings these deposits above sea level. The diatomite is easily mined this way, however, being in marine areas, pollution in the water is a big concern.
Through the use of many mining machines, the waters can be easily polluted. The method of dredging to cut away at the sediment does not seem like it would be as environmentally friendly as well. Aside from the mining having impact on the actual land, diatomite mining has impacts on birds in surrounding areas. Many birds show a tendency to avoid dredging areas. Besides factors of noise and pollution and general unpleasantness of machines, birds also rely on animals in shallow water for food where dredging has occurred.

...any different areas. I feel that mining of this product is worth the impact it leaves on the environment.
I was most likely taking diatomite for granted. I was not even aware that it was a product, let alone that it was useful in different ways. A lot of things I use daily would not be the same without the use of diatomite. I drink soda every day, and I would not get that drink if it were not filtered. I’ve never even wondered about how water in a swimming pool is filtered, yet if it were not, I’m positive swimming would not be as enjoyable in the summer. I like the fact that diatomite seems incredibly useful for very important things, such as toxic waste, antibiotics and water filtration. I also think it is exceptional because it goes to use for so many different products.
Some things that are mined can only go to a few things, whereas diatomite can go from cleaning toxins, to paint fillers, to filtering wine, to insecticides. I don’t like diatomite for the fact that it is not being recycled, and that no recycling programs are being put into use right now. Overall I think that diatomite is a worthwhile product and beneficial to consumers every day.
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.
Molybdenum is a transition metal. It is represented by the symbol Mo. It is a pure metal that is is silverish white in color and very hard, and has one of the highest melting points of all pure elements at 4753 °F. Its boiling point is 8382 °F. Its density is 10280 kg/m3 and its hardness is 5.5.

Barium is a soft, heavy, silver-colored metal element. This element does not have very many uses outside of the laboratory, but it combines easily with other chemicals to form compounds used for important industrial uses. For example, Barium carbonate is used in the manufacture of ceramics and special glass, and also to purify certain chemical solutions. It is also an ingredient in clay slurries, also known as water muds, used in drilling oil wells. Barium titanate is used in sonar detectors and other electrical equipment. At low doses, barium acts as a muscle stimulant and at higher doses affects the nervous system eventually leading to paralysis. Acute and subchronic oral doses of barium cause vomiting and diarrhea, followed by decreased heart rate and elevated blood pressure. Higher doses result in cardiac irregularities, weakness, tremors, anxiety, and dyspnea. A drop in serum potassium may account for some of the symptoms. Death can occur from cardiac and respiratory failure. Acute doses around 0.8 grams can be fatal to humans. Barium nitrate makes signal flares burn with a green flame. Barium ferrite is used to make magnets. Barium sulfate is an extremely insoluble barium compound that is not poisonous. Doctors use it in X-ray examinations of a patient's digestive system. The barium sulfate absorbs X rays to show an outline of the intestines on the developed film. A barium enema is performed to examine the walls of the colon. During the procedure, a well lubricated enema tube is inserted gently into the rectum. The barium is then allowed to flow into the colon. The flow of the barium is monitored by the health care provider on an X-ray fluoroscope screen. The test is used to detect colon cancer. The barium enema may also be used to diagnose and evaluate the extent of inflammatory bowel diseases. Barium sulfate and zinc sulfide form lithopone, a white coloring matter for paint. Barium is never found in a pure state because it combines so easily with other elements. Pure barium is obtained by passing an electric current through a fused barium compound, such as barium chloride. A piece of barium metal quickly reacts with oxygen and water vapor in the air to form barium oxide. It must be stored under kerosene to keep it pure. Barium is found most often as barium sulfate in the mineral barite. The chemical symbol for barium is Ba.
All tech is viewed as a means to improve your life, make it happier and easier.
The major technology change that has had the greatest impact on the quality of my life is the spread of uses for the Internet. The wide range of uses for the internet has extremely benefited my life. I use the Internet to keep in touch with my family from College and with my brother who is in the Air Force in Georgia. I also use the Internet to talk to my long-distance boyfriend so my phone bill doesn't get too large. I also use the Internet in a highly educational way. Not only can I take my college courses online (which is much better for me because I teach myself much better than a professor or teacher can teach me), but it can teach me about anything else I would like to know.
In Chemistry, Neodymium is one of the 118 elements found on Mendeleev’s Periodic Table. An element is a substance that is made entirely from one type of atom and is then advantageously placed in the periodic table which categorizes all elements of the universe. Neodymium was discovered to have a “twin element” and is used for anything from high-powered fans to cellular phones.

...many benefits for us, but it is not really needed all the time. Maybe in some situations for people technology is needed every day in their lives. But the fact is that people don’t really need all these new gadgets, they didn’t have all of this kind of stuff back in the day, and they still mad it through. Education is being helped by technology and sometimes just giving the student the answer. Later on though it can affect the student when a more difficult situation comes, they will not know what to do.
I now apply technology to many different aspects of my life including academics, personal, and recreational. I am now able to choose wisely between different types of technology and am able to distinguish between the different options that I have. I also have a much better understanding of the wide variety of programs that are accessible to me and I am able to use them with a basic understanding of how they work.
Femicide is defined as the act of killing a female simply because she is female. Acts of femicide includes “honor killings,” “dowry deaths,” genital mutilation, rape in war and victimization o female refugees. The treatment of women prisoners and detained immigrant women are also related to the issue of femicide. Essentially, femicide is a form of gender-based violence (Stuart van Wormer & Bartollas, 2011). It is considered to be an extreme form of gender-based violence that may include torture, mutilation, cruelty and sexual violence. The violence often culminated to murder. This violence is linked to gender concepts like inequality, discrimination and disempowerment (Femicide, 2008). It is also viewed as “a form of terrorism that functions to define gender lines, enact and bolster male dominance, and to render women chronically and profoundly unsafe” (Suarez, 2009). Based on international federal and state law, women have the right to be free from violence. Overall, acts of femecide are viewed as a violation of the human rights of women (Femicide, 2008).
