Andy Berger: A Summary

Pages 3
In this article the author, Andy Berger, explains how scientists are making magnets out of two non-magnetic metals. The researchers have used copper and manganese to create this. In order to get magnetism out of these metals, scientists use what’s called a buckyball. A buckyball is a molecule that’s completely carbon. This soccer-ball-shaped molecule has strong electron affinity which is similar to electronegativity. The carbon atoms are able to accept electrons from the metals and can be measured. Essentially these carbon atoms pull the electrons out of an adjacent metal. The scientists take these buckyballs and make a thin layer of them, followed by a layer of one of the 2 metals. These will be layers on a non-magnetic chip. At only 20 nanometers thick, when the stack was taken away from the magnetic field, it kept a weak magnetization. Scientists continued experimenting with the layering of buckyballs and either copper or manganese and found that the more alternating layers, the stronger the magnetic field.
This combination of metal and buckyballs is very …show more content…
I’ve never been a science wiz, so even from the point of understanding that copper and manganese are elements, and elements are on the periodic table, BUT only a few of the elements are metals helped sort out the article for me. Then, when the article mentioned electron affinity I did a quick google search and was very proud of myself when thinking “This sounds a lot like electronegativity.” After researching a comparison of the two I learned that they are very similar. So, by knowing electronegativity from CHM 110 its helped me understand electron affinity which then made the article make much more sense. Also CHM 110 taught me a whole bunch about carbon and how it’s a very important element for many reasons including its ability to accept electrons to fill its shell, confirming that carbon was a great atom element to use in this

...Openflow Virtual Networking: A FlowBased Network Virtualization Architecture Georgia Kontesidou Kyriakos Zarifis Master of Science Thesis Stockholm, Sweden 2009 TRITA-ICT-EX-2009:205 Openflow Virtual Networking: A Flow-Based Network Virtualization Architecture Master Thesis Report November 2009 Students Kyriakos Zarifis Georgia Kontesidou Examiner Markus Hidell Supervisor Peter Sjödin Telecommunication Systems Laboratory (TSLab) School of Information and Communication Technology (ICT) Royal Institute of Technology Stockholm, Sweden 2 Abstract Network virtualization is becoming increasingly significant as other forms of virtualization constantly evolve. The cost of deploying experimental network topologies, the strict enterprise traffic isolation requirements as well as the increasing processing power requirements for virtualized servers make virtualization a key factor in both the research sector as well as the industry, the enterprise network and the datacenter. The definition of network virtualization as well as its manifestations vary widely and depend on the requirements of the environment in which it is deployed. This works sets the foundation towards a network virtualization framework based on a flow-based controlled network protocol like Openflow. 3 Abstract Så småningom, har nätverk virtualization blivit signifikant. Hög kostnaden för att utveckla experimentella nätverk topologier, noggranna kraven för en effektiv trafik isolering...

A leak of methyl isocyanate gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people. The toxic substance made its way in and around the shantytowns located near the plant.[2] Estimates vary on the death toll. The official immediate death toll was 2,259 and the government of Madhya Pradesh has confirmed a total of 3,787 deaths related to the gas release.[3] Others estimate 3,000 died within weeks and another 8,000 have since died from gas- related diseases.[4][5] A government affidavit in 2006 stated the leak caused 558,125 injuries including 38,478 temporary partial and approximately 3,900 severely and permanently disabling injuries.[6] UCIL was the Indian subsidiary of Union Carbide Corporation (UCC), with Indian Government controlled banks and the Indian public holding a 49.1 percent stake. In 1994, the Supreme Court of India allowed UCC to sell its 50.9 percent share. Union Carbide sold UCIL, the Bhopal plant operator, to Eveready Industries India Limited in 1994. The Bhopal plant was later sold to McLeod...

Yet when we recall the discussions we’ve had with colleagues about instructor’s manuals over the years, two unnerving comments stick with us: “I don’t find them much help”; and (even worse) “I never look at them.” And, if the truth be told, we were often the people making such points! With these statements in mind, we have done some serious soul-searching about the texts that so many teachers—ourselves...

As part of Ofcom’s work to promote media literacy we plan to undertake or support a range of research activities to monitor people’s skills, knowledge and understanding of communications technologies and the content they watch and listen to either through broadcasting or online. Ofcom defines media literacy as the ability to access, understand and create communications in a variety of contexts. We have published our strategy and priorities for the promotion of media literacy and these can be found on our website. In October 2004 we commissioned Professor David Buckingham and Professor Sonia Livingstone to report on recent relevant academic and other publicly-available research into children’s and adults’ media literacy respectively. The purpose of this work was to outline the range of studies conducted, the gaps in research, provide examples of innovative methodologies, and outline possible barriers and enablers to media literacy identified by these studies. These reviews have admirably fulfilled their task, and provide a...

Cognitive Poetics

...This page intentionally left blank This practical coursebook introduces all the basics of semantics in a simple, step-bystep fashion. Each unit includes short sections of explanation with examples, followed by stimulating practice exercises to complete the book. Feedback and comment sections follow each exercise to enable students to monitor their progress. No previous background in semantics is assumed, as students begin by discovering the value and fascination of the subject and then move through all key topics in the field, including sense and reference, simple logic, word meaning, and interpersonal meaning. New study guides and exercises have been added to the end of each unit (with online answer key) to help reinforce and test learning. A completely new unit on non-literal language and metaphor, plus updates throughout the text, significantly expand the scope of the original edition to bring it up-to-date with the modern teaching of semantics for introductory courses in linguistics as well as intermediate students.
