Name: Class: NT1310 Date: November 30‚ 2013 Assignment: Unit 1‚ Lab 1: Data on Fixed Line vs. Cellular Debate Fixed Line vs. Cellular Debate As many as one in six American households have given up their landline and are using only their cell phone‚ according to Steven Blumberg‚ a senior scientist at the Center for Disease Control’s Statistics department. If you are among the millions of Americans who are weighing the pros and cons of landlines vs. cell phones‚ here

Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

Unit 1. Lab 1. Fixed Line vs. Cellular Debate A cellular network or mobile network is a wireless network distributed over land areas called cells‚ each served by at least one fixed-location transceivers known as a cell site or base station. In a cellular network‚ each cell uses a different set of frequencies from neighboring cells‚ to avoid interference and provide guaranteed bandwidth with each cell. When joined together these cells provide radio coverage over a wide geographic area. This enables

INTRODUCTION Vapour absorption refrigeration system is one of the oldest methods of producing refrigerating effect. John Leslie in 1810 kept H2SO4 and water in two separate jars connected together. H2SO4 has very high affinity for water. It absorbs water vapour and this becomes the principle of removing the evaporated water vapour requiring no compressor or pump. H2SO4 is an absorbent in this system that has to be recycled by heating to get rid of the absorbed water vapour‚ for continuous

Nuclear Fission v. Nuclear Fusion Similarities DIfferences Both fission and fusion generate energy. During both processes neutrons are released. Both processes create elements with a lesser mass. Both fusion and fission processes are capable of creating a nuclear bomb. Nuclear Fission When large unstable nuclei decompose into smaller stable nuclei. Produces a lot of radioactive particles. Nuclear Fusion A nuclear reaction when a larger nucleus forms when the nuclei of two atoms fuse together

What is nuclear medicine? Nuclear medicine is a division of medical imaging that detects and treats diseases and irregularities in the body such as cancer and neurological illnesses through the use of radioactive chemicals. The techniques used in nuclear medicine allow physicians to attain knowledge about patient conditions without the invasion of personal space through procedures such as biopsies. The equipment and machines used within this branch are important for research as they allow for a better

Can Nuclear Energy Be the Answer? It is only possible to mitigate global warming if the world-wide consumption of fossil fuels can be drastically reduced in the next 10 to 15 years. There is simply no room for a scenario as it is depicted by Lester R. Brown in the book Plan B 4.0 Mobilizing to Save Civilization. The scenario plays out like a horror movie‚ poverty‚ depleted water supply‚ food shortages‚ terrorism‚ over population‚ disastrous floods‚ erratic changes in ocean currents and global

Absorption of different cloth diapers Problem The purpose of this experiment is to determine which type of cloth diaper can absorb the most amount of water before coming out in any way (either through the diaper or out the sides). Relevance There are many types of cloth diapers on the market these days. They are very expensive and I believe that most parents would like to buy a cloth diaper that has the most absorption. No one wants to put any diaper on their child that will leak through

Nuclear and Radiation Accidents Since the beginning of the Atomic Age‚ the use of nuclear energy technologies has been accompanied by numerous crises and persistent public health concerns. Currently‚ nuclear power has become an indispensable part in the ongoing search for alternative energy sources. By “January 2011‚ 442 nuclear power plants operated globally to supply a total of 400‚000 megawatts of energy‚ or roughly 14% of the total global energy supply”(Wisconsin Institute par.2). Yet with
