CYBER TERRISOM INTRODUCTION: Cyberterrorism is the use of Internet based attacks in terrorist activities‚ including acts of deliberate‚ large-scale disruption of computer networks‚ especially of personal computers attached to the Internet‚ by the means of tools such as computer viruses. Cyberterrorism is a controversial term. Some authors choose a very narrow definition‚ relating to deployments‚ by known terrorist organizations‚ of disruption attacks against information systems for the primary

able to use infrared satellite imagery. Infrared satellite imagery is able to look down on an open area and see what is located under the surface of the ground. Explorers had used this to uncover what the old civilizations looked like through the satellite. When a Egyptoligist named Sarah Parcak‚ and people in her team looked at an area they selected‚ "They found 1‚000 tombs‚ 17 potentially buried pyrimids‚ and about 3‚000 settlements."(Source 3‚ Paragraph 3) One thing that the infrared satellite imagery

Moles 1.How is molar mass calculated and why is it useful? You have to multiply the atomic weight of each element by the number of atoms that it contains in a compound. Molar mass is useful because its used to change a measurement of mass to an amount of a substance such as the number of particles. 2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations. A mole measures the amount of a substance. Three examples that are equivalent to a mole is molar

PASADENA‚ Calf. -- The true identity of centaurs‚ the small celestial bodies orbiting the sun between Jupiter and Neptune‚ is one of the enduring mysteries of astrophysics. Are they asteroids or comets? A new study of observations from NASA’s Wide-field Infrared Survey Explorer (WISE) finds most centaurs are comets. Until now‚ astronomers were not certain whether centaurs are asteroids flung out from the inner solar system or comets traveling in toward the sun from afar. Because of their dual nature

Telescopes in Astronomy SCI/151 Telescopes in Astronomy Telescopes are one of the greatest inventions and have led scientists on a fantastic journey of getting closer to understanding the universe. There is no way to research and evaluate outer space without telescopes gathering all of the information that they do. This paper is going to discuss the science of telescopes and explain all of the elements relative to them. How telescopes changed our view of the universe Without telescopes

Infrared Spectroscopy is used to identify molecules by giving structural information about a molecule. Based on the knowledge that CH bonds have an absorption rate of 3000+-100cm-1 and that C=O bonds (carbonyl groups) have a 1700+- 100cm-1 absorption rate. I was able to locate these types of bonds on the Infrared Spectroscopy reports done by Dr. Yamaguchi. I don’t have enough expertise on how to decipher

the form of infrared radiation. Some of the outgoing infrared radiation is trapped by the layer of atmosphere and held inside the atmosphere‚ and that’s a good thing because it keeps the temperature of our earth within certain boundaries‚ keeps it relatively constant and liveable. But the problem is this thin layer of atmosphere‚ is being thickened by all of the global warming pollution being put up there. And what happens because the atmosphere is thickened more of the outgoing infrared is trapped

Have you ever wondered why we see the grass green or the ocean blue ?. Liquid water absorbs short wavelength light (UV)‚ long wavelengths and infrared light. Each color has a different wavelength‚ so it is refracted at a slightly different angle‚ resulting in dispersion. The colors visible spectrum results in the light response‚ the absorption‚ reflection‚ transmission and in the color addition/subtraction. Out of the visible light spectrum the most absorbed is the red-orange along with the yellow-green
