...the Hole In The Ozone Global warming and the hole in the ozone layer are two topics that are frequently debated in the scientific community. After researching the two phenomena I feel that they are both very closely related, but I do not feel that one is the main cause for the other or that they share the same main cause. As far as the two producing the same effect, I do believe there may be some credibility in that theory. The hole in the ozone layer is caused mainly by the use of chlorofluorocarbons, or CFCs, which are most prominently found in aerosol based products, and halon which was produced mainly for use in fire extinguishers up until 1994. The two chemicals in CFCs that are most detrimental to the ozone layer are chlorine and bromine. Although the chemicals in CFCs are considered to be potent greenhouse gasses, they are not found in the atmosphere in a high enough concentration to be considered a main cause of the hole in the ozone layer. (Lindsey, 2010) Halon was produced for use in fire extinguishers until 1994 when the Clean Air Act banned the production of new halon. It was banned because there was no cost effective way to safely and effectively dispose of it and it was also proven to be harmful to the ozone layer. Halon is still used in fire extinguishers today, but all halon based extinguishers are now produced with 100% recycled halon. (CleanAgents, Inc. 2015) I do not feel that the hole in the ozone layer is the cause of global warming because the hole allows...

...Have you read the book Holes? Have you noticed that Stanley changes throughout the book? Before Stanley went to Camp Green Lake, he was selfish and did not have a great childhood because he would get made fun of in school. Stanley Changes throughout the book because of his friendship with Zero. Before his time at Camp Green Lake and at the beginning of his time there Stanley was looked down upon by others. “Be cool” said X-Ray he put his hand on Stanley’s shoulder.”You don’t want to mess with the Caveman,” he warned.”The Caveman is cool” said Armpit. (Sarchar 44) The text evidence proves that they look down on Stanley by saying that Caveman is cool and looking after him.” Then he returned to Zero, who had been quietly digging in his hole since...

...Global Warming During the last 50 years, two environmental issues have received significant attention—global warming and the hole in the ozone layer. As scientists have investigated these two environmental phenomena, some have made some effort to show that these two effects are somehow related. The rate at which global warming is occurring is a controversial subject among scientists. Because scientists have been studying the earth’s weather patterns for only the last century or two, it is difficult to make an accurate comparison of the recent weather data to the overall weather patterns of a planet that has existed for millions of years. Consequently, it is hard to know whether rising temperatures are a cyclical phenomenon or a trend that could have devastating effects on our planet. Very simply, global warming may be thought of as excess heat being trapped near the surface of the earth. Think about how hot a car becomes while parked in the sun on a summer day. The inside of the car is hotter than the surrounding air because the glass of the windshield allows the electromagnetic waves from the sun to pass into the car but does not allow the resultant heat to pass back out. In a similar manner, the burning of fossil fuels (coal, oil, gas, etc.) produces a layer of gases (commonly referred to as the greenhouse gases) that acts like the windshield of a car. This layer of gases allows the electromagnetic waves from the sun to pass through but does not allow the heat from...

This shows in my research by giving us evidence on how the ozone can affect our health and everyday life style and the radical changes we would have to make within a short amount of time if this continues and we actually create a huge hole in our ozone. 2. http://www.esrl.noaa.gov/csd/assessments/ozone/2010/preface.html * This is a great article with multiple resources talking about a wide range ozone effects and how to counter act them and the potential future of our ozone if we can try and make the changes now then late. They talk about the policies in place to prevent manufacturers to use when using gases or harmful substances in every day products. This can be used in my research by showing what every day products that we use for our showers or hair, cars, gas, garbage, pollution can affect our ozone and this will give us ways to better our ozone. 3. http://ucanr.org/repository/cao/landingpage.cfm?article=ca.v049n03p24&fulltext=yes * This article gives you information on what the ozone is and how its created and what this does for our planet and this goes into how the ozone can be depleted and also gives you a lot of information on the agriculture part of how our economy can be affected with crops and farmers and important vegetation we have to grow. This can be used in my research for how the ozone effects multiple aspects...

...How would you feel if you were cursed? Well, in the book Holes Stanley Yelnats was cursed. It all started when he was sent to Camp Green Lake. Before Stanley went to Camp Green Lake he was wimpy and relied on his parents, but after he went he was independant and had learned to take risks. Stanley has been cursed his entire life for something his ancestor Elya Yelnats did. Elya made a deal he did not follow through with. Elya was in love with a girl named Myra ( Sachar 28) and wanted her hand in marriage, so Elya went to his good friend Madam Zeroni ( Sachar 28). Madame Zeroni told Elya that he take one of her piglets and carry it up the mountain everyday and let the piglet drink water whilst he sing a song. and on the last day Elya must carry...

...very scary in this book. Being with friends can help. Stanley Yelnats did not always have friends. At the beginning of Holes, Stanley was scared, but because of Zero he was brave by the end. Stanley was scared in the beginning because he did not know anybody. He was the new guy at Camp Green Lake. He had to go to the camp because they thought he has stole shoes, but he did not steal them. He thought he was going to get hurt. When he was in his cot, he thought it would break. Stanley was afraid of what would happen because of the curse. The curse was from his “no good, dirty rotten, pig stealing, great-great grandfather”. The curse would effect Stanley’s life immensely. Stanley was very scared because of all the things at Camp Green Lake and he did not have any friends to talk to in the beginning. At the end of the book, Stanley was brave because of Zero. Zero helped him have confidence. Everyone at the camp trusted Stanley. One of the campers named Squid asked Stanley to call his mom and apologize for him. Stanley taught Zero how to read and write even though other campers made fun of him. Stanley found his way back to camp with the help of Zero. They did not have any water, only had onions to eat, had to walk really far and they were alone. Zero and Stanley help each other even in the worst times possible. At the beginning of Holes Stanley was scared, but because of Zero he was brave by the end. This impacts Stanley’s future because he doesn’t have to...

...CAE Software of Twin-Tubes Shock Absorber Outer-Characteristic Changcheng Zhou, Jie Meng School of Traffic and Vehicle Engineering Shandong University of Technology Zibo 255049, China greatwall@sdut.edu.cn Abstract The pathway throttle and local throttle loss of oil flow in telescopic shock absorber were analyzed, and the pathway loss coefficient and equivalent length of piston holes were studied. According to the thickness and the pre-deformation of throttle slice, and the throttle holes area, the velocity points of valve opening were researched and the analytic formulas of shock absorber velocity when valve opening were given. With the velocity points of valve opening, the model of shock absorber outer characteristic was established by piecewise linear math function. Based on this, the CAE software for shock absorber outer characteristic was developed. A practical example of simulation of shock absorber outer characteristic was given with this CAE software, and the performance test was conducted to verify the CAE software. The results show that the CAE software is reliable, and the values simulated is close to that tested. 1.

...Holes is a novel which was created by Louis Sachar. The novel won awards for the 1998 U.S. National Book Award for Young People's Literature and the 1999 Newbery Medal for the year's "most distinguished contribution to American literature for children". It is a great novel that my class read and hear are the top 3 reasons why it is a great novel. The three things that make it a great novel are the link ups, the backtracking and the character descriptions that Louis Sachar wrote. My opinion on why Holes is a great novel is because of all the link ups in the story. The link ups in the story bring the story together and it is genius of Louis Sachar to do this because it make the audience want to read more. In the book Elya Yelnats gets cursed by Madam Zeroni until the 4th generation when Stanley Yelnats carries Hector Zeroni up the mountain and sings the song. After, the curse is broken. Trout Walker looks for the treasure that kissing Kate Barlow stole from Stanley Yelnats the first but when he has a baby girl she digs as well. Then she becomes the warden of Camp Green Lake and makes the other boys dig for the treasure. Then when Stanley and Hector find the treasure, they find Stanley’s name on it so they get to keep it....

...THE IMPORTANCE OF PROTECTING NATURE Nature is God’s greatest boon to mankind. Nature is the mother of all creations on our earth. The air that we breath, the water that we drink, the food that we consume, the furniture that we use, etc. are all gifted by Mother Nature. If not for nature life on earth would have been unimaginable. The bright sunshine, the beautiful mountains, the showers of rain, the tamed and wild animals, the gems and the jewels, the paper on which we write all are the presents of Nature. We as humans owe our very existence to Mother Nature but seem to disregard this inimitable fact and do not pay any respect to her instead we indulge in polluting and destroying our environment. Today, people uproot & trees for furniture but forget to plant a new sapling in its place. The tragedy of modern day existence is people are enjoying luxury items such as cars, air-conditioners refrigerators, etc. failing to realize that they are polluting the ecological balance of our earth. Today’s generation seems to have no moral responsibility towards nature. The ecologists, scientists and environment activists all over the world have realized the need for protecting nature and its natural resources. The major problems that our earth is struggling are with pollution, population, depletion of mineral resources, global warming, extinction of various species of animals and cutting down of forests. Our beautiful earth is turning into a defaced, ugly surface of...

...Environmental health addresses all the physical, chemical, and biological factors external to a person, and all the related factors impacting behaviours. It encompasses the assessment and control of those environmental factors that can potentially affect health. Although many air pollutants are invisible, they can seriously impact our health, the environment, and our quality of life. Air pollutants may cause respiratory diseases, cancer and other health effects. Pollutants also may create odours and smog, diminishes the protective ozone layer, and contributes to other environmental problems, such as acid rain and global climate change. The air inside homes, schools, and other buildings also may contain pollutants that enter from outdoors and those generated indoors. Mold, radon, tobacco smoke, carbon monoxide, and chemical emissions from products and furnishings are some of the important pollutants that may be present in our homes and other indoor environments.(Frumkin:2010) Particulate matter (PM) affects more people than any other pollutant. The major components of PM are sulphate, nitrates, ammonia, sodium chloride, carbon, mineral dust and water. It consists of a complex mixture of solid and liquid particles of organic and inorganic substances suspended in the air. The particles are identified according to their aerodynamic diameter, as either PM10 (particles with an aerodynamic diameter smaller than 10 µm) or PM2.5 (aerodynamic diameter smaller than 2.5 µm). The latter...

...Air Pollution Problem in Bangladesh SUBMITTED TO- SUBMITTED BY: ASSIGNMENT Introduction Air pollution is one of a variety of manmade environmental disasters that are currently taking place all over the world. Air pollution may be defined as an atmospheric condition in which various substances are present at concentrations high enough above their normal ambient levels to produce a measurable effect on people, animals, vegetation, or materials. ‘Substances’ refers to any natural or manmade chemical elements or compounds capable of being airborne. These may exist in the atmosphere as gases, liquid drops, or solid particles. It includes any substance whether noxious or benign; however, the term ‘measurable effect’ generally restricts attention to those substances that cause undesirable effects. Air quality has deteriorated both due to human activities, and natural phenomenon such as wind-blown dust particles etc. There are two major sources of air pollution in Bangladesh, vehicular emissions and industrial emissions. However, these are mainly concentrated in the cities. Recently, air pollution has received priority among environmental issues in Asia, as well as in other parts of the world. Exposure to air pollution is the main environmental threat to human health in many towns and cities. Particulate emission is mainly responsible for increased death rate and respiratory problems for the urban population. This problem is acute in Dhaka being...

...be able to produce a drill that will be able to go down that deep and rescue the miners? Will it take them three or four months to drill a hole before the miners are free? Thirty-Three Chilean workers trapped in a mine Thirty-three Chilean miners trapped in a mine in San Jose under Atacama Desert with very little oxygen, food and water. All thirty-three miners were underground for 17 days before their first contact from the outside world. Codelco mining company is a state owned company in Chile, that was in charge to drill three small bore holes into the ground which was the first break through to reach the workers, allowing the rescuers to be able to communicate with them and send them food and medicine. The companies plan was to bore a rescue hole that would pull the miners up from 2,300 feet of the earth. First, they have to drill a pilot hole in the earth that is similar to a borehole. This would make the hole wide enough to establish some form of communication, sending down a camera to see how the miners were holding up 2300 feet below the earth surface, allowing them to speak into the camera to their family members. After drilling the first phase, they will than use another cutter machine that is bigger and drilling in the same spot as the previous holes allowing the holes to become wider. The miners have to aid by...
