Rubidium
Rubidium is a chemical element that was discovered in 1861 by Robert Bunsen and Gustav Kirchhoff, in Heidelberg, Germany through a scientific process of flame spectroscopy. During the process, Kirchhoff and Heidelberg noticed bright red lines in its emission spectrum which caused them to choose the name Rubidium derived from the Latin word rubidus, meaning "deep red". Rubidium is a chemical element with symbol Rb and atomic number 37 and an atomic mass of 85.4678. Rubidium is a soft, silvery-white metallic element which gives the reason why it is located in the alkali metal group on the periodic table. It is a highly reactive metal and is arguably one of the most reactive elements on the periodic table. It undergoes violent reactions such

    Barium Essay for Chemistry

    In 1808 Barium was isolated by an English chemist named Sir Humphry Davy by electrolysis of molten baryta or BaO. But it was discovered in 1779 by Carl Scheele. Barium is classified as an alkaline-earth metal. Its atomic number is 56 and it is the fifth element in group 2.Natural Barium is made up of a mixture of seven stable isotopes, there are thirteen radioactive isotopes known to exist. Barium has never been found in nature in its pure form. When Scheele discovered barium in the 1700's he could not isolate it he could only isolate the barium oxide. Another person to isolate the barium oxide was a man named Johan Gahn but he did it two years after Scheele did. Davy who finally managed to isolate barium on its own, did it by analogy with calcium and decided to name it Barium after the word baryta. Pure oxygen used to be produce through the Brin Process before they started using barium peroxide to liquefy air and produce oxygen. Barium appears as a silvery white color metal. Barium van be found anywhere in the environment because it exists there naturally. Barium has many compounds that are used today mostly industrially. Barium is very light and has half the density of iron. Barium oxidizes air and reacts with water to form the hydroxide that liberates hydrogen. Barium reacts with most non-metal to creating poisonous compounds. After…

    Radiant Red Rock

    One of the most unique and special National Parks to me is Zion in Utah. The Colorado Plateau region lies along the side of Zion. This Park is very beautiful and has many different attributes to it but with out a doubt its red dirt and mountains are wonders. Zion is 229 square miles (147,551 acres) and has around 75 species of mammals, 271 birds, 32 reptiles and amphibians, 8 fish. The rock layers have been through so much; for example, they have been uplifted, tilted, and eroded, forming a feature called the Grand Staircase. This incredible landmark also carries the Virgin River right through it. My experiences at Zion have been only but amazing, I have learned so much and enjoy being surrounded by such a radiant red rock. I have found that this park has much history to still be found. What I have come across to be most interesting at this National Park is the Virgin River, Checkerboard Mesa and the Sedimentation taken place.…

    Riace Bronzes

    The Riace Warriors were discovered by Stefano Mariottini on August 16, 1972, on the bottom of the Ionic Sea near Riace Marina in Calabria in Italy. The statues have been dated to roughly 450BC. The statues' eyes are inlaid with bone and glass, the lips and nipples are made from copper while the teeth are silver. Both statues at one point held spears and shields; however, those have not been recovered. Both statues stand firmly on the right foot, with the left foot forward and left knee relaxed. The right hip is thrust out with the right hand lowered at the side. The left forearm is raised to hold a shield and the head is angled to the right (Mattusch 1996).…

    Gadolinium

    Gadolinium is a paramagnetic metal icon. These paramagnetic icons move differently within a magnetic field in which these make the gadolinium useful for something more familiar in today’s medicine such as MRI. Gadolinium helped doctors and medical professionals to be able to see a patient’s internal organs, inflammation, tumors, blood vessels, and tissue. The quality of MRI’s are enhanced by altering the magnetic properties of water molecules when gadolinium is used. Gadolinium used by itself is toxic, but when it is used in contrast agents it bonds with a molecule called a chelating agent. This controls the distribution throughout the body. The chelating agent controls the toxicity of the contrast and helps maintain the magnetic properties.…

    The Riace Bronzes

    The first room of the gallery belongs to the Greek era of artwork and contains two sculptures. The Riace Bronzes, which is the first sculpture, consists of two naked life size Greek soldiers and was created around 460-420 b.c.e. This two-piece sculpture is important to the Greek era because it is one of the only original bronze pieces left from this time period. The joint sculpture was formed with a wax technique that is now lost, and marks the transition from the archaic Greek style to the early classical by joining the two together. The two statues are formed in impossible proportions which make them god-like and lean more towards archaic Greek art, but the statues are also in a moving position, not rigid, which is indicative of the early…

    Black Gold

    The film Black Gold was a very interesting and eye opening film. The film focuses mainly on the coffee growers in southern and western Ethiopia. The movie shows closely the journey that Tadesse Maskela goes through to promote his union- Oromia Coffee Farmers Cooperative Union. The union was developed to cut out the middleman in the processes of trading and exporting the coffee beans. Tadesse Maskela also attempts to secure a living wage for the coffee farmers that her represents, and hope to have fair trade for social and economic justice. The union’s goals are to stabilize the local markets in and outside of Ethiopia, to improve the Ethiopian coffee market, and most importantly to improve the quantity of life of the coffee farmers. I find this very important because it really opened my eyes and realize that the farmers make very little or no money at all for every cup of coffee that we drink. The movie shows the drastic challenges that the farmers go through. Children are malnourished, uneducated, bad living conditions, and most importantly their work is not paying off. These farmers work eight to twelve hour shifts and make as little as fifty cents a day. The film Life and Debt showed similar issues like the ones in Black Gold. In Life and Debt we saw how due to regulations from the IMF and World Bank, farmers who produced bananas and milk lost profits due to trade regulations made and that other countries producing it at a lower price. This caused the bananas and milk to rot and the conditions and profits of the farmers worsen. The thing that I picked up form both films is that we need to be more aware of where and how we get what we have. We need to know who is affected through the process of getting this product. It always seems that the little farmers are getting hurt, while big corporations are just gaining the…

    Nuclear Power in the Present and Future

    Uranium is an element that was integrated into the planet during the Earth's formation from the dust of shattered stars. It was discovered by Martin Heinrich Klaproth in 1789 and although Klaproth thought the compound he extracted was pure uranium, it was actually uranium dioxide. Today, uranium is obtained from uranium ores such as pitchblende, uraninite, carnotite, and autunite. It can also be found in phosphate rock, lignite (brown coal) and monazite sand. There three different types of isotopes that can be found: uranium-234, uranium-235 and uranium-238. All three isotopes are radioactive, but uranium-235 is the only fissionable isotope that can be used for nuclear power. (Gagnon)…

    Element Neon

    Neon is the Element I’m interesting in. I choose to do neon because I found out the uses that are in our daily life. Neon was discovered by Sir William Ramsay in 1898 (England). Sir William Ramsay was a Scottish chemist who discovered it through the study of liquefied air. The name neon originates from the Greek word neos meaning new. Neon is the forth most abundant element in the universe. Neon is the element that allows you to watch TV, and without neon we would never see the cool flashing signs outside the bars, clubs, and restaurants. I’m going to tell you about neon’s uses, history, and facts. The largest use for Neon is in advertising signs. Neon is also used to make high voltage indicators. I’m going to give you the chemical breakdown of neon. Neon is on the periodic table, its atomic number is 10, protons, electrons are 10, 10 neutrons and its symbol is Ne. Neon is a noble gas. The period of neon is 2, and the group is 18. Neon is very rare on earth even though it’s very common element in the universe. In the earth's atmosphere, neon only comprises 0.0018 percent of the volume. On the earth, neon is always present as a gas. Neon has three stable isotopes, and it’s the second lightest noble gas, after helium. Two different types of neon are commonly used in the world. Neon glow lamps are tiny; they have been used as power on indicators. Neon is not a very common element, but the places it is most abundant is in the earth’s atmosphere, and trapped with in rocks in the earth’s crust. Neon signs operate at much higher voltages. Neon is not known to toxic, and it doesn’t have any stable compounds. Neon is just a light it’s an inert gas. Neon mixed with some other elements can make a bright light in an enclosed tube. When under low pressure, neon emits a bright orange-red glow if a small electric current is passed through it. It’s colorless but glows reddish orange electric discharge. Neon is an element classified as a noble gas which can be located in the…

    Opal (gem)

    Opal is the most rare and valuable gemstone in the entire world. Every single opal is different and unique. You will never be able to find an opal that is exactly the same as another opal. They are found all over the world. All opal gemstones are considered gemstones, and not semi precious stones, because of its quality and rarity. Opals are usually opaque but can sometimes be translucent or even transparent. On Moh’s Scale, the opal’s hardness is 5.5 – 6.5. This is relatively soft, so opal is sometimes coated with a thin layer of clear quartz. This is to make the opal more resistant to scratches. These are called opal doublets or triplets. An imperfection of the opal is crazing. That is when the gemstone is damp and then dried too quickly or suddenly exposed to intense light, which forms internal cracks.…

    1. Dataset For this tutorial, we will work on some unlabeled data from the US Census Bureau. The following introduction to this dataset is for you to learn about its attributes and interpret results: Attributes of the raw data is discretized to have less attribute values, which is the data we are seeing now. Attributes description of the raw data attributes is at: http://archive.ics.uci.edu/ml/databases/census1990/USCensus1990raw.attributes.txt Some attributes are kept the same from raw dataset to the current dataset, with an “i” attached to the front of current attribute name indicating it’s unchanged; the discretized attributes of raw data set are named with a “d” added in front of their original names. For example, in current data set, attribute “dAge” is discretized from raw data set, and its description should be “AAGE” in the raw data description (Age); “iAvail” means the attribute values is not changed from its raw values, and its corresponding attribute is “AVAIL” in raw data description (Available for work). For more information, the mapping functions from raw attributes to current attributes can be found here: http://archive.ics.uci.edu/ml/databases/census1990/USCensus1990.mapping.sql The file used in this tutorial is an abbreviated version of the data set, obtaining the first 10,000 instances out of 2,458,285. [Note: If your computer does not have big memory, you will notice the following clustering process is executed very slowly. Then you may use the file UScensus_3000.xlsx to do this Lab. This file has only 3000 instances, although it may not get as interesting results as the larger file, it should take much less memory than the larger set with 10000 instances.] Start RapidMiner and ReadExcel UScensus_10000.xlsx, and set role of the “case ID” to be id, then store the dataset to your repository (please recall tutorial 2 on importing and storing data).
