secret message from a third party. The most popular modern application of steganography involves concealing messages within least significant bits of image or sound files. Another application of modern steganography is a steganographic file system. Steganography is also used by some modern printers‚ where tiny yellow dots that contain encoded printer serial numbers‚ as well as other information‚ are added to each printed page. I chose modern steganography as a topic for my course paper primarily

road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a certain concentration of road salt will have an affect on a specific type of plant. Also to see what changes will occur like the color of the plant will change or the height of the

Galileo Galilei is one of the most well known and popular scientist beside Albert Einstein. At the very basis of what he did‚ Galileo changed how people looked at the world around them especially the solar system. Eventually the church held a trial against Galileo on the act of heresy and attack on the Aristotelian idea of the universe as the church and many others believed that the earth was at the center of the solar system not the sun. He also had many inventions which helped future scientists

Chem-102 Lab Dr. Sobhi Experiment #3: Spectrophotometric Determination of Tartrazine Purpose The objectives of this lab include- illustrating the use of the spectrophotometer in chemical analysis‚ and generating a standard‚ or calibration curve‚ then using that curve to determine the value of an unknown substance. The spectrophotometer is one of the most powerful tools used in chemistry to find the concentration of substances in solution. It compares the colors of a known and an unknown solution

Modern medicine has made life more comfortable‚ and humans are living longer‚ healthier lives thanks to discoveries like penicillin to treat bacterial infections and vaccines to prevent deadly diseases like diphtheria‚ tuberculosis and tetanus. In 1920 there were 206‚000 reported cases of diphtheria‚ and of those 15‚520 deaths were reported. Between the years of 2004 to 2008 there were no reported deaths related to diphtheria. The first vaccine to treat diphtheria was created in 1921‚ but not widely

Psychology Experiment No. 2 Effect of Inconsistency of Objects in Scenario on Perception Introduction: In our everyday lives‚ we are used to seeing objects within their particular characteristic scenarios. For example‚ it is nothing to wonder if we see a person browsing the internet in a computer lab or a car speeding on a road. However‚ when we see an object which is inconsistent with the environmental setting‚ we do feel alarmed. Thus‚ it is shocking for us to see someone working on a

Science and Scripture Galileo Galilei was an Italian astronomer‚ mathematician‚ and natural philosopher who made paramount contributions to science as we know it today. At a time of a growing polarization of thought on the motions of heavenly bodies‚ Galileo took a stance in support of the Copernican theory of heliocentrism— with the sun being placed at the center of the solar system rather than the biblical teachings at the time of a geocentric‚ Earth-centered model. When writing his “Letter to

The singular deviation during this experiment was that we did not centrifuge the tube (for 5-10 seconds) after incubation. The mitochondrial DNA was amplified in sterile 0.5 ml PCR tubes. The reaction in tube one contained‚ 2 µl of our genomic DNA‚ 1 µl JOSH01 (a 10 µM forward primer) and 1
