Vulcanizing mold To form a tread on green tire, a mold must mold and melt the rubber. The inside circumference of the circular tread face part of the mold that will be in contact where the tread of the green tire will be is a negative shape of the tread to be on that green tire to be shaped. The outside of the circular tread face is in contact with the pre-heating or curing molds inside circumference. The tread shapes on the tire is formed by ribs and/or lugs on the inside of the circular…
My second critical response essay is on the reading Getting Fossil Fuels Off the Plate by Michael Bomford. This reading is about how food is grown, processed, and transported around the world and how much energy it takes to get food from its origin to your plate. Our aptitude to obtain food with ease is our most treasured resource, but regrettably our present structures of food production, especially agriculture, are causative to the failing strength of the world’s air and water, while…
Gunpowder is one of china’s four greatest inventions. Gunpowder is an ancient chemical explosive that was accidently created by Chinese Taoists who were attempting to create a portion of immortality by combining salt peter, sulfur, and charcoal. There are multiple types of gun powder: Black powder (organic), black powder (modern / synthetic), cordite, smokeless ball powder (aka spherical powder), smokeless flake powder (found in shot shells), and smokeless stick powder (aka extruded powder).…
At Pyro’s Academy, we have a lot to offer and to teach you! For example, you learn about the different types of chemical reactions such as combustion and displacement, how to write word equations about chemical reactions and the difference between exothermic reactions and endothermic reactions. To write combustion as a word equation you would write ‘___ -> Oxygen = ___ Oxide’ so if the element you were burning was Iron, the product would be Iron Oxide. In a chemical reaction, the surroundings…
Anhydrous ammonia is the target of methamphetamine (meth) producers after it spilled out the derailed train cars 10 days ago in Stoughton. Anhydrous ammonia is a key ingredient in the production of meth, the highly addictive, central nervous system stimulating drug. Meth has a high potential for abuse and dependence, and is very easy to make when utilizing anhydrous ammonia. Two tankers that remain at the crash site still have anhydrous ammonia inside of them. These tankers are now under…
In contrast, Hurst believes that industrial farmers are environmentally responsible, changing industrial farming will inflate food prices and potential starvation, and realizes that we can’t change nature; we must use what we have. Hurst points out that “The biggest environmental harm I have done as a farmer is the topsoil (and nutrients) I used to send down the Missouri River to the Gulf of Mexico before we began to practice no-till farming, made possible only by the use of herbicides. The…
E. I. du Pont de Nemours and Company was the first company to manufacture domestic supply of high quality gunpowder .In 1802, the DuPont family began their industrial business in the United States by building the Eleutherian Mills on the Brandywine Creek in Delaware. This was the beginning of an extensive scale gunpowder production in the United States. Guncotton, also known as nitrocellulose, was invented in 1845 by German chemist Christian Schonbein. The purpose of this invention as to create…
Did you know that at one point, the United States had a fear that they would run out of natural gas? Roughly a decade ago, industry analysts and government officials became worried that the United States would run out of natural gas, a source of energy in the states. A solution to this predicted problem would become hydraulic fracturing, also known as fracking. Developed more than sixty years ago by George P. Mitchell, fracking is the process of pumping millions of gallons of chemically treated…
2. Introduction Nitrogen fertilizer can aid increase crop production and provide more food for the growing population. Since earlier ages, people has shown preoccupation about soil fertility and soil exhaustion (Strawn, Bohn, & O'Connor, 2015). Some management practices such as manure application or crop rotation were known by Chinese 3000 years ago (Strawn, Bohn, & O'Connor, 2015). However, it was just in the last-century that the crop yield increased dramatically. Improvements of hybrids, soil…
Lots of American farmers found themselves unable to make enough money to support their families. One of the main ingredients of Moonshine is corn. A farmer could take a subpar corn farm and turn it into a goldmine. Obviously the Government did not approve of this practice. There are a couple good reasons for the Government to oppose this practice. With underground Moonshine sales growing they were losing a large amount of tax revenue; secondly, there was no way to regulate production, and…
