The Chosen Affinity: Uprising 1 They all said life would be better here. Trapped in a tiny train with about 6 other people. We were around 15 years old, some older, some younger, three guys and three girls. The train took off yesterday with no known location. My twin brother and I had received a letter in the mail a few weeks prior. Mine came with a one way ticket and a letter my parents had quickly snatched from me and would not allow me to read. After they had fallen asleep however, I snuck…

message could actually understand the speaker. Although the telephone was expensive, it took communication and made it easier. Cell phones today are made out of several components such as the following: “glass, aluminum, lithium cobalt oxide, carbon graphite, gold, copper, silver, platinum, tungsten, and plastic” (Wagner). These materials were not readily available in the time of Alexander Graham Bell, but they are used thoroughly today. Glass is used for the screen, the metals are used for the…

book describes the process of the meltdown in detail, explaining that the temperature of the reactor rose with the lack of coolant flowing through it, which led to an accumulation of steam and pressure and, because of the type of core, a Uranium- graphite core, the emergency protection systems’ effectiveness were significantly reduced (Medvedev, 75). Medvedev continues, explaining that as the amount of pressure in the reactor continued to increase, the feedback valves of the main circulation…

All districts, except District 6, have access to the government owned train, but it is very expensive to use. There is only one way citizens can use the train at no cost, and that is if they are chosen as tributes for the Hunger Games. In District 12, Katniss Everdeen volunteered as tribute in place of her sister. Her family is not wealthy so she got to ride the train to the Capitol for the first time, “Of course, I’ve never been on a train, as travel between districts is forbidden except for…

High temperature proton exchange membrane fuel cells (HT-PEMFCs) are a promising clean technology, especially for automobile applications.1 These devices generate electricity from the chemical reactions that occur in the anode side of the cell, using H2 as a fuel and generating heat and water as by-products.2, 3 However, experimental studies using HT-PEMFCs show that degradation of the cell can occur after certain hours of operation (around 500 hours).4 Some of the factors that contribute to the…

History of Atomic Absorption Spectroscopy (AAS) Atomic Absorption Spectroscopy (AAS) was first proposed by Alan Walsh, later known as Sir Alan in 1955. Sir Alan worked in Melbourne for the Commonwealth Scientific and Industrial Research Organization (C.S.I.R.O.). This concept came to Alan Walsh in a flash of inspiration as he was gardening at his Melbourne home. This led to the invention that has since been labelled as one of the most significant achievements in chemical analysis for last…

The National Aeronautics and Space Administration’s (NASA) Mars Exploration Rover Mission (MER) is an ongoing space exploration mission of the planet Mars utilising two robotic rovers named Spirit and Opportunity launched on June 10 and July 7, 2003, respectively from Cape Canaveral, Florida, USA [1]. The mission’s primary goal is to “Determine Whether Life Ever Arose on Mars” (NASA) through the search for clues in soils and rocks that suggest past water activity on the planet’s surface. The…

Child Labor in the Developing World In the latest International Labour Organization (ILO) report the organization found that there are an estimated 246 million child laborers. Of those 246 million, 179 million work in rigorous labor conditions (Azhar, 2015, p. 73). Some of the most common forms of child labor include work in sweatshops and mines. Children in sweatshops can work up to 12 hours per day for as little as a dollar per day (Collingsworth, Goold, & Harvey, (1994), p. 2) . Because of…

I had originally planned to meet Sachy, Alvaro, and Victoria at the Getty, however both these plans fell through as we all clearly have very poor organization skills. So on a breezy Sunday Morning I embarked on a solo mission to LACMA. Well not really because my mother was lovely enough to accompany me. When I initially woke up that morning, I was overcome with regret of waiting until the last weekend to get this assignment done. The whole ride there, the clouds threatened rain and my mother…
