Pros and Cons of MTBE in Gasoline
MTBE, or methyl tertiary butyl ether, is an oxygenate commonly used in gasoline in America, Europe, and other countries throughout the world. It is a compound created by the chemical reaction of methanol and isobutylene that is added to gasoline because of its high octane level, allowing gasoline to reach the required octane levels and still include a gasoline component. In addition, because it is an oxygenate, MTBE helps gasoline more fully combust, which increases performance and reduces the amount of harmful pollutants such as CO, VOCs, NOx, and particulates released into the atmosphere from automobile exhaust [EFOA]. However, opposition has recently arisen against the use of MTBE in gasoline.
Every underground gas tank eventually leaks, and the gasoline is soaked up by the surrounding ground. MTBE is not soluble in water; therefore, when the gasoline leaks out of the tank, the MTBE pollutes the ground water (well water), and eventually the surface water also. In addition, though MTBE reduces the amount of most pollutants released from automobiles, it also produces a harmful pollutant, formaldehyde, when combusted [CECA]. Even worse, a study performed by a medical researcher from the University of Pennsylvania, shows that MTBE may be the cause of a seventeen percent increase in asthma among kindergarten students since it has been utilized in gasoline. The study also shows that MTBE has failed to improve smog levels in the years it has been in use [Jones].
Therefore, is MTBE good or bad? It is still early to give a definite answer, however the banning of MTBE in many states in the US in exchange for its most common alternative, ethanol, shows signs that MTBE is doing more harm than help. To be fair, if more strict legislation were to be passed to force gas stations to maintain leak free tanks, much of MTBE’s pollutant problems would be solved.
1984 demonstrates a dystopian society in Oceania by presenting a relentless dictator, Big Brother, who uses his power to control the minds of his people and to ensure that his power never exhausts. Aspects of 1984 are evidently established in components of society in North Korea. With both of these society’s under a dictator’s rule, there are many similarities that are distinguished between the two. Orwell’s 1984 becomes parallel to the world of dystopia in North Korea by illustrating a nation that remains isolated under an almighty ruler.
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans. The efficiently burning shale gas reduces carbon emission from electricity production plants, reducing carbon footprints on the environment. However, the process of hydraulic fracturing uses millions of gallons of pressurized liquid, which contains toxic chemicals, and some of this water is left over undealt with. The air near fracking sites is often also polluted and unsafe for nearby community residents. Injecting millions of gallons of water laced with toxic chemicals into the rock thousands of feet deep can cause earthquakes, causing a safety hazards for all nearby areas. Hydraulic Fracturing makes rare natural gases easily attainable, boosting the economy and reducing carbon emissions. However, the negative side effects such as contaminated water and air, make hydraulic fracturing a process that may not be worth the benefits.
North Korea is notorious as the “Hermit Kingdom”. Defensive and secretive to the point of paranoia, its history as well as its present conditions remains shrouded in mystery. What little we do know can be murky at best. The central govern...
Rogue states under dictatorial rule threaten the fragile peace, which exists in our modern world. Constantly as a society Americans have always fought against these said foes. However all too often we pass a blind eye to the humanity of the enemies’ civilian populations. For more often than not, those who live within these systems are chronically oppressed. The nation of North Korea is no exception, with “Bing-brother always watching.” The government in North Korea pervades all aspects of life.

Ripped Fuel is a dangerous supplement and it is important that my cousin and his parents know what Ripped Fuel is and the present and long term effects of using this product. Even at an appropriate age, taking Ripped Fuel can have negative side effects on the person consuming it. A few of these side effects include: insomnia, nervousness, and headaches; all of which are caused by the high doses of caffeine. In more serious cases, there have been reports of heart palpations, tremors, and agitation. A majority of weight loss supplements increase the amount of water consumed by the body and Ripped Fuel is no different. If one does not intake the required amount of fluids while taking Ripped Fuel, their body will experience dehydration.
North Korea is very mysterious and isolated from the rest of the world. Very little is known about what actually happens in the state. This isolation began in 1945 when Kim Il-Sung came to power of the Democratic People’s Republic of Korea (also known as North Korea). He started a reign of rule that was based on self-reliance. It began the Kim dynasty, a period of extreme authoritarian rule. Although it is called the Democratic People’s Republic of Korea, citizens have very little rights and no choice in their leader. Ironically, the Democratic People’s Republic of Korea comes in last of 167 countries in the democracy index. (“Liberty and Justice for Some”) Under the rule of Kim Il-Sung, Korea entered the Korea War, which strained relations with other countries. North Korea then grew more into isolationism and more into poverty. Under the rule of Kim Jong-Il, North Korea became very involved in nuclear weapons that resulted in strained relations with the United Nations and its member states. When Kim Jong-Un came into power, the citizens have suffered from lack of rights and crimes against humanity. The Kim dynasty has harmed North Korea’s citizens and its chances of becoming a world power.
McDonalds. What had started as a humble family owned drive-through has become a multi-million dollar industry. Everywhere one goes, there are reminders of how amazingly widespread this company has become, whether it be seeing McDonald’s famous golden arches on a billboard or hearing the catchy “I’m Lovin’ It” tune in a commercial. But more than this, McDonalds has become part of our global identity– our McWorld.
Many hazardous pollutants escape from the internal combustion of the engine. Conventional gas powered vehicles use irreplaceable fossil fuels to run. When burned, these fossil fuels create numerous toxins like carbon dioxide (Larminie 246). Carbon dioxide is considered the main greenhouse gas that creates the foundation for global warming (hybridcars.com, pollutants). This harmful pollutant may not have a serious effect on people at first, but it does have consequential effects on the environment that in turn put people in danger (Nutramed.com). The major consequence caused by global warming is the rise in average temperature. This results in a domino...
North Korea’s extremist actions cannot be excused as simply maintaining homeland security. Instead, North Korea has gone and created a dictatorship where citizens are ruthlessly controlled and isolated to avoid the inward or outward spread of facts contrary to the claims of the imperial Kim family. The brainwashing, restrictions on freedom and communication, and exile from the outside world have created a society in which North Korea’s citizens have lost their basic human rights.
McDonalds provide high quality products, such as burgers, fries, drinks, muffins, etc, which are safe and reliable that it does what it is supposed to do, but not only does the quality of the products matter, the good value for money affects the business. E.g. buy one extra value meal and get one free with a food voucher that represents the offer only. They ensure that a high standard of the product is carried out at all times and they try to compete very competitively with other fast food businesses with their good value for money. Also a customer would know if the product is good value for money by checking in another food outlet like KFC for their services and products.
In today’s market, McDonalds faces numerous challenges such as fierce competition, a more health conscious customer, and the continual need for improved customer satisfaction and menu. McDonalds needs to go through some changes in order to remain ahead in the fast-food industry.
Throughout history, tragic events or situation accrue that change the point of view of a country, its culture, and its people. In North Korea’s condition, it is a country regarded in a negative manner by most of the world. Most people view its government as inhuman and reluctant or resistant to change. North Korea is a failing regime and a country with many problems. It has limited natural resources and many of its people live in poverty and are confined from the outside world. In this essay we will briefly review North Korea’s culture, society, geography, climate, past military conflicts, economy, military, and government.
When a customer enters a McDonalds restaurant he should feel differently than any other stores. McDonalds restaurants are not just about physical location or distribution networks for its products. Restaurants have a different significant role. The Role is to create an atmosphere where the customer can come back again and again. Another role of the restaurants is the management decisions of a range of processes involved in delivering the products to the end customer. McDonalds restaurants are well spread across the most popular and crowded locations that are very convenient to most of consumers. A good idea of McDonalds was keeping the restaurants opened until late night to appeal to young adults who like to party or going out.
Factories and transportation depend on huge amounts of fuel--billions of tons of coal and oil are consumed around the world every year. When these fuels burn they introduce smoke and other, less visible, by-products into the atmosphere.
