MEN 510 Energy Conversion Assignment 2 Proton Therapy Presented to: Dr. Walid Assaf By: Farid Akiki 20082191 Semester: Fall 2012 Proton Therapy Proton therapy (also called proton beam therapy) is a type of radiation treatment that uses protons rather than x-rays to treat cancer. A proton is a positively charged particle that is part of an atom‚ the basic unit of all chemical elements‚ such as hydrogen or oxygen. At high energy‚ protons can destroy cancer cells.

Learner Autobiography Learner Autobiography Demetria J. Pipkin ED7311 Theory and Methods of Educating Adults Growing up I always attended magnet schools once I entered the public school system in Third grade. Magnet schools are public schools with specialized courses or curriculums. In grades 3-12‚ I attended Communication Arts magnet schools. As a child I never had the desire to be in the "communication field" so I never understood why my Parents enrolled me in these types of schools

The Differences in Preparation between the ADN and BSN Dana Grand Canyon University: NSR- 430vProfessional Dynamics September 22‚ 2013 Many people from all walks of life decided to go back to school in an effort to obtain a job so they can afford to care for their family. It may be a single mom or dad‚ some one that is older‚ a young student who is fending for themselves‚ no matter what the story they have to start somewhere. Prior to becoming a nurse‚ one doesn’t understand the real difference

Superconductivity Jaron Hartman In collaboration with Stefan Eccles Senior Lab Abstract: Superconductivity is the phenomena of a material to have an electrical resistance of zero when cooled to a certain temperature known as the critical temperature. The phenomenon of superconductivity was first observed in 1911 by Heike Kamerlingh Onnes when cooling mercury down to a temperature of 4.2 K. Since then‚ many advances in the field of superconductivity have been made. In 1986‚ superconductivity

Remove iron with magnet 2. Add water to the mixture to melt the benzoic acid and NaCl then filter out sand. 3. Chill the solution and scoop the acid out leaving a salt solution. 4. Boil water away leaving salt. Purpose: The purpose of this lab is to learn

The magnet rotates because each time it is either repelled or attracted by the permanent magnet and has to move that way.)
