...Hydrofracking in Marcellus shale: The Consequences of America’s Gas Rush Introduction Demand for fossil fuels in America has led to a flurry of unorthodox methods for the extraction of natural gas. Fracking or hydrofracking in the U.S.A has proven to be an efficient way of extracting natural gas from permeable rock. A new large scale hydrofracking operation has been proposed in the eastern states of Ohio, Pennsylvania and New York. This method of extraction is highly controversial, and is thought to have severe environmental and potential health consequences. This essay will provide further insight into the practice of Fracking in an area of shale known as Marcellus shale, and help to expose the environmental and human implications. What is Hydrofracking? Hydraulic Fracturing is an un-conventional process used in the extraction of gas in permeable rock (David 1973). A horizontal well is drilled into permeable rock such as shale and is injected with millions of gallons a high pressure fluid known as frac-fluid, this fluid is a mixture of sand, water, and an array of lubricating chemicals (Deutch 2011). The high pressure frac-fluid forces open fishers (cracks) within the rock which are kept open with sand granules; this allows pockets of gas to flow more easily from the shale (David 1973). Once the well is depleted all fluid that can be recycled is extracted, and the well is capped to stop any unused gas escaping (David 1973). The process of fracking is expensive and requires...

...Robert Hoefer Professor Arenson English 101 17 July 2012 Common Ground Essay The first commercial coal mine in America was started in the 1748. ("History of US Coal Use.") The first commercial oil well in the United States was drilled in 1859. (Yergin, 7) These two fossil fuels were the power behind the American Industrial Revolution, and wealth behind Edward Berwind and John Rockefeller(Brinkley, 435), respectively, that continue to provide power and fuel in present day society. Natural gas is another fossil fuel that helps to provide for the needs of today. Oil, coal, and gas companies tout new technologies that make their products cleaner and safer for the environment. Opponents of fossil fuels say there is no way to burn them cleanly. Proponents for fossil fuels believe there are plenty of reserves to keep America running on fossil fuels for years to come. Advocates for newer technologies, “green” technologies, such as solar power, geothermal energy, and biofuels claim that the time to move on from these fossil fuels has arrived. The new energy sources claim to be renewable so as to never run out. (E.g., the sun would have to supernova for solar power to run out.) They believe the point of “Peak Oil”- the point at which worldwide oil production begins to decline, has already passed and the country will need their new technologies to keep pace during the changing of the energy guard. There are many lenses through which to look at the use of all these energy sources...

The reason why Prozac and similar drugs are so popular, might not have so much to do with how effective they are, which there is substantial doubt about, but in the perception of the public that they are effective. This belief is due to the heavy marketing behind drugs in general and antidepressants in...

...the questions. Candidates with disabilities may request a time extension. Meteorite Impact and Dinosaur Extinction There is increasing evidence that the impacts of meteorites have had important effects on Earth, particularly in the field of biological evolution. Such impacts continue to pose a natural hazard to life on Earth. Twice in the twentieth century, large meteorite objects are known to have collided with Earth. 5 If an impact is large enough, it can disturb the environment of the entire Earth and cause an ecological catastrophe. The best-documented such impact took place 65 million years ago at the end of the Cretaceous period of geological history. This break in Earth’s history is marked by a mass extinction, when as many as half the species on the planet became extinct. While there are a dozen or more mass extinctions in the geological record, the Cretaceous mass extinction has always intrigued paleontologists because it marks the end of the age of the dinosaurs. For tens of millions of years, those great creatures had flourished. Then, suddenly, they disappeared. The body that impacted Earth at the end of the Cretaceous period was a meteorite with a mass of more than a trillion tons and a diameter of at least 10 kilometers. Scientists first identified this impact in 1980 from the worldwide layer of sediment deposited from the dust cloud that enveloped the planet after the impact. This sediment layer is enriched in the rare metal iridium and other elements that are relatively...

...process in morally wrong due to the vast quantity of water which is required in order for fracking to take place while others believe that fracking is responsible for the increase in earth tremors. On the Other hand Pro-fracking groups believe that the claims regarding the negativity surrounding the dangers of Fracking are unfounded and the process is completely safe. The issue of fracking in the area has seen the emergence of groups with polarising points of view, those who believe that fracking will benefit the local region and those who believe that fracking will cause long lasting damage to the environment, local wildlife and the health and wellbeing of the local community. This essay will look at the historical context of the issue and the underlying causes of the conflict to date. The essay will also look at the main stakeholders involved in this issue and will put forward proposals to transform the conflict into a situation which is satisfactory for everyone concerned.

...ANNOTATED SELECTED BIBLIOGRAPHY FOR HISTORICAL INTERPRETATIONS OF THE INDUSTRIAL REVOLUTION IN BRITAIN Gerard M Koot History Department University of Massachusetts Dartmouth Allen, Robert C., The British Industrial Revolution in a Global Perspective, New York: Cambridge University Press, 2009. Pp. viii, 331. Allen’s book is an excellent example of the persuasiveness of the new economic history. It is solidly rooted in statistical data and uses sophisticated methods of economic analysis but its analysis is presented in plain English. He argues that the first industrial revolution occurred in northwestern Europe because its high wages during the early modern period encouraged technological innovation. Although high wages were initially a consequence of the demographic disaster of the Black Death, they were reinforced during the early modern period by the economic success of the region around the North Sea, first, in European trade and manufacturing, especially in wresting the textile industry from the Italians, and then in world trade. According to Allen, the first industrial revolution took place in Britain instead of the Low Countries primarily because of Britain’s abundant and cheap coal resources, combined with the central government’s ability to use mercantilist policies and naval power to reap the greatest benefits from an expanding European and world trade. Once it had taken the lead from the Dutch, and defeated the French, Britain used its comparative advantage...

...These pages were downloaded from Writing Personal Statements Online, available at https://www.e-education.psu.edu/writingpersonalstatementsonline/ Short Personal Statement by a Geology Student Growing up in Canada with a life-long fascination for Canadian geography, I have always been interested in returning to the country. Although my family moved to the US before I entered high school, I have always kept my eyes turned north, especially in recent years as I began to read journal articles about research conducted on John Evans Glacier, located about 80° N latitude. Graduating next semester with a B.S. in computer science and engineering and a minor in geographic information systems, I am interested in attending the University of Alberta for graduate study. Geographic information systems (GIS) is a field especially suited to investigating spatial patterns, modeling diverse scenarios, and overlaying spatial data. This semester, in my advanced GIS course, Spatial Data Structures and Algorithms, I am part of a team developing a temporal database and program for tracing historical trading data. My computer science skills have also been put to use in two summer internship projects, where I acquired proficiency with using LIDAR (light detection and ranging) technology, now favored by NASA in its current 10-year study of Greenland and changes in the ice cap extent. Through my coursework and project experience, I have also accrued skills...

...Energy, Infrastructure and Communications I n tandem with the pick-up in overall industrial growth, core industries and infrastructure services have also evinced signs of recovery with easing of supply bottlenecks in certain sectors and demand recovery in others. The robust growth momentum in telecommunications, particularly the wireless segment, continues with monthly additions exceeding 17.6 million connections. In the midst of the worstever slowdown in the history of world civil aviation, even the modest levels of growth in India are indicative of resilience. Core industries like power, coal and other infrastructure like ports and roads are also reviving. Available evidence points to a steady revival of flows of investible resources. However, the levels of broadband penetration, capacity creation in some crucial infrastructure sectors and the state of development of markets for longterm finance remain causes for concern. There is need to develop infrastructure to complement and sustain the economic growth momentum. Efforts—legislative, administrative and executive—are on to minimize the infrastructure deficit, ameliorate bottlenecks in completion of projects and nurture core industrial intermediates and infrastructure services. 10 CHAPTER 10.2 The stimulus measures announced by the national authorities worldwide to combat the economic slowdown contained infrastructure buildup plans. In line with the rest of the world, the Union Budget for 2009-10 substantially stepped...
