Author used their literacy work to get a message a Essays - Film

Author used their literacy work to get a message across to the people about the story "The Crucible". The author miller use events and characters to show his message of McCarthyism. McCarthyism was a time were Joe McCarthy accused Americans of being communist and in the crucible people were accused of being witches. It is known that miller wrote this story as a reaction to a tragic time in history which they showed injustice and power which both situation people were and found guilty without any evidence. The actions of characters reveals miller message of McCarthyism because he states similar things that happen during the trial of McCarthyism which was just like the trial held in the crucible by the deputy governor. Bearing to send her away to be hang with no proven facts that she was a witch and lying to the deputy and being let off shows the author message of McCarthyism on this being injustice. In the text it stated that Abagail and Betty were accusing multiple people of witchcraft.in the text it states "he sentenced her. He must but not Sarah good. For Sarah good confessed y'see". Stated in lines two-hundred and nineteen thru two-hundred and twenty seven. The action which the girls accused many people were most effective because it end up being nineteen people being hanged. While Sarah good had confessed, goody Osborn had not confessed and was still was put in jail to be hanged. Also you couldn't tell who was lying or telling the truth. Also in lines 1105 thru 1114 it states "(pointing a t proctor ). You're the devil's man! (He stopped in his tracks)". This shows that after the girls making Mary warren to be the witch she blame it on proctor. Mary warren, Abagail, and Bett y actions show injustice because the deputy couldn't tell if they were lying or telling the truth and he still didn't have any evidence and some people have the power to make people form a lie of injustice to the wrong people being the victims. Furthermore, the deputy governor has the power and so does Abagail who the one is preventing someone to tell the truth on her to being a witch. In line 1070 thru 1100 it states "do you confess this power? (He is an inch from her face.) Speak". This states that Abigail's new founded power are used to make Mary warren to be the witch and force her not to tell on her and what they did in the forest. Also in act three it states "and folks are brought before them, and if they scream and howl and fall- the person clapped in the jail for bewitching' them". This shows if you scream and make a whole bunch of noise the deputy will let you go free. This is show the power of the deputy is used to condemned people. To conclude, McCarthyism is the message Miller was trying to reveal in the story to show that there were injustices and overused of power of the powerful leaders. Also it was unfair because you couldn't have done anything and if you were accused, you were force to go on trial with no evidence. It not your fault can't nothing be done but lie to get out of being hang would you lie knowing that you weren't involved or apart of witchcraft?

Water Desalination

Water Desalination Desalination (also spelled desalinization) is the process of creating fresh water by removing saline (salt) from bodies of salt water. There are varying degrees of salinity in water, which affects the difficulty and expense of treatment, and the level of saline is typically measured in parts per million (ppm). The U.S. Geological Survey provides an outline of what constitutes saline water: 1,000 ppm – 3,000 ppm is low salinity, 3,000 ppm – 10,000 ppm is moderate salinity, and 10,000 ppm – 35,000 ppm is high salinity. Water that contains saline levels less than 1,000 ppm is generally considered fresh water and is safe to drink and use for household and agricultural purposes. For a reference point, typical ocean water contains about 35,000 ppm, the Great Salt Lake contains variations of 50,000 – 270,000 ppm, and the Caspian Sea contains an average of about 12,000 ppm. The more concentrated saline is in a body of water, the more energy and effort it takes to desalinize it. Desalination Processes Osmosis Reverse Osmosis There are several setbacks of reverse osmosis. The membranes are currently prone to gather too much bacteria and â€Å"clog up,† although they have improved since they were first used. The membranes deteriorate when chlorine is used to treat the bacteria. Other setbacks are the arguable water quality that reverse osmosis produces, along with the considerable pre-treatment that the salt water requires. Forward Osmosis Pressure gradient desalinating water The main setback to forward osmosis is that it has great potential, but is still fairly new to large-scale desalination and therefore needs funding and research to explore the possibilities that could improve it and reduce energy costs. Electrodialysis Thermal Desalination Multistage Flash Distillation Multiple-Effect Distillation Negatives of Desalination Fossil fuels Geography of Desalination Middle East Saudi Arabia is currently the world’s number one producer of desalinated water. They use multi-flash distillation in several large plants, providing water for many large cities, including the largest city, Riyadh, situated hundreds of miles from the coast. In the United States, the largest desalination plant is located in Tampa Bay, Florida, though it has a very small output compared to most facilities in the Middle East. Other states that are developing plans for large desalination plants include California and Texas. The United States need for desalination plants is not as severe as many other countries, but as the population continues to explode in dry, coastal areas, the need increases. Future Options of Desalination Desalination is a process primarily done in developed countries with enough money and resources. If technology continues to produce new methods and better solutions to the issues that exist today, there would be a whole new water resource for more and more countries that are facing drought, competition for water, and overpopulation. Though there are concerns in the scientific world about replacing our current overuse of water with complete reliance on seawater, it would undoubtedly be at least an option for many people struggling to survive or maintain their standard of living.
