Advances in technology has brought many benefits but also problems. The use of new technology creates moral and ethical problems and conflicting attitudes in society. The complexity of the issues and the pace with which technology changes mean that legislators have difficulty making laws that can keep in control of these changes. Technology affects all areas of society‚ forcing changes in a range of laws. Advances in computer technology have resulted in a new brand of cyber crimes such as computer

LS1120 Practical 3 ABSORPTION SPECTRA AND THE BEER-LAMBERT LAW The purpose of this practical was to measure the amount of a chemical substance present in a sample. Primarily‚ the aim of Experiment 1 was to measure the absorption spectrum of a particular coloured substance (in this case Bromophenol Blue and Methyl Orange) at varying wavelengths of light. For Experiment 2‚ the process of the experiment focuses on the substance and records its absorption levels at different concentrations. The

Sigmund Freud Sigmund Freud was one of few amazing physicians. He was born in 1856 in a small town in Freiberg‚ where he then moved to Vienna around the age of four (Freud X). When Freud was seventeen years old he began his scholarly career at the University of Vienna‚ eight years later he completed with a degree in physiology and neurology (Freud X). Freud was the father to many great theories and ideas that are still used today in psychology. Freud was the father of psychoanalysis‚ came up

Objective The objective of this lab is broken into two parts. The first is to recognize the principles of flame ionization and atomic spectra. The second is to observe and thus further understand the line spectra for multiple elements or molecules as well as determine the correlation between emission spectra and atomic structure. Experimental Procedure Procedure 1: Observation of Line Spectra by Discharge Tubes Six discharge lamps were selected – argon‚ carbon dioxide‚ helium‚ hydrogen‚ iodine

Sample Business Plan This is a sample business plan that I completed by myself for a Entrepreneur class in my Senior year of high school. Unlike most students‚ I was really excited to plan and organize my ideas so my plan ended up being much longer then expected. All the numbers I used were‚ for the most part‚ actual prices and I spend hours alone just number crunching. It was worth it in the end when I had my final copy! I apologize in advance for awkward spacing‚ numbering‚ and indents. Some things

Ashley Spees CHM 261- Batzer Chem Final Write Up- Kool Aid Lab Total Acid This part of the lab requires titration of Kool Aid with an NaOH solution. The reason titrations are used is to determine the concentration of an unknown solution by reacting a strong acid with a strong base. Titrations are hard to accomplish‚ though‚ due to the fact that indicators used to show the endpoints are very sensitive and one drop could make the solution titrate past its endpoint.
