Ozone (O3) Depletion The ozone is a molecule that contains three oxygen atoms and has a strong odor. It is also blue in color. This is much different than the oxygen that we breathe in that it is odorless and colorless. Since around the 1970's there has been a severe problem happening in our Earth's stratosphere. The Earth's ozone layer has been in a great decline of about four percent in total volume observed since then. There are two different but related issues that are happening from mankind which are the steady loss of the ozone in the stratosphere and another loss of the ozone near the Polar Regions called the ozone holes. The way we are finding out how the ozone is depleting is through many observations of computer models and of the atmosphere. We can also introduce chemicals and other substance reactions in a laboratory environment to study what it does to an atmospherically setup like the earths. Through all of these studies we have found that certain chemicals and there are several in particular that increase the rate of depletion in the ozone but the biggest leader in the depletion of the ozone is Chlorofluorocarbons or CFC's and we will get into that later. An example to show how we are losing the ozone layer in our troposphere is a river. A river usually flows at the same level just as the ozone is moving around but remains at the same level. Once mankind starting introducing these chemicals and other elements into the atmosphere it is lowing the level of ozone before it can be remade again. This is

where we are seeing a loss in our ozone and a rise in projects to slow down the emission of CFC's and other things harmful to the ozone.
We will now get in depth with the reasons why ozone depletion is happening on earth. The ozone is divided into several different layers that are spread across the troposphere and the stratosphere. The troposphere…...

COMPSTAT uses Geographic Information Systems (GIS) to map the locations of where crimes occur, identify “ hotspots”, and map problem areas. COMPSTAT has amassed a wealth of historical crime data. Mathematicians have designed and developed algorithms that run against the historical data to predict future crimes for police departments. This is known as predictive policing. Predictive policing has led to a drop in burglaries, automobile thefts, and other crimes in some cities.

...Assignment 1: Essay Due Week 4 and worth 100 points Read the selection in the textbook. Write a three to four (3-4) paragraph essay (250 words) which analyzes the “surprise ending” of the reading selection. APA format. Topic Choices: * Reading selection from Swift’s A Modest Proposal. Swift begins with offering the solution that the English could do things which might solve the problem of over-population and the mistreatment of citizens in Ireland and ends by offering the solution that an internal change in the Irish government would best solve the problem of over-population and a populace victimized by its own government. Read more about A Modest Proposal located at http://www.victorianweb.org/previctorian/swift/modest.html. For the reading selection you choose: 1. Clearly state in your own words the “surprise ending” in the reading you selected. Identify the point in the reading when you realized that the ending would be different from what the beginning of the reading suggested that it would be. 2. Since you were expecting a different ending, evaluate how successful the author was in convincing you to accept the validity of the “surprise ending” that was not clearly suggested at the beginning. * Include a cover page containing the tile of the assignment, the student’s name, the professor’s name, the course title, and the date.

The marketing group worked for months with a top advertising firm on the campaign. Their effort was successful in terms of significantly higher demand for Napanee Beer's keg beer at sports stadiums. However, the production department had not been notified of the marketing campaign and was not prepared for the increased demand. The company was forced to buy empty kegs at a premium price. It also had to brew some of the lower priced keg beer in vats that would have been used for higher priced specialty beer. The result was that Napanee Beer sold more of the lower priced keg beer and less of the higher priced products that summer. Moreover, the company could not......
