Perhaps the earliest indicator of the theory was the apparent fit of some of the Earth’s continents; analysis of these coastlines, notably the eastern edge of South America and the western edge of Africa, has shown that they are very similar geologically suggesting that at some point in the Earth’s history the landmasses were joined together. Another indicator that the continents were once distributed differently was geological evidence of glaciation in India – it is unlikely that glaciers could ever reach such low latitudes, but this problem can easily be explained by continental drift. Fossil distribution also provided some of the earliest evidence for plate tectonics – certain land-dwelling fossil species have been found in areas that are now separated by ocean which indicates that those areas were at some point joined together. However at the time of Wegner’s work many of the geophysical tools that are used today did not exist making the theory much more difficult to support. Paleomagnetism is one of the strongest pieces of evidence for plate tectonic theory and was developed in the 1950s which managed to convince scientists of the validity of the theory. When new crust is formed certain minerals align themselves with the Earth’s magnetic field. Analysis of the Mid-Atlantic Ridge has shown that as you move outwards from the ridge, the polarity of the sea floor alternates and the age of the sea floor increases; the...

...Parker Earth Moving Company Consulting: Session Three John Flynn, Lakeidra Haygood, Dwann Herron, Rosy Manivong, and LaTasha Snowden ISCOM/305 June 13, 2011 Kairo Hannon Memorandum TO: Parker Earth Moving Company FROM: Team B Consulting DATE: June 13, 2011 SUBJECT: Business Process Improvements Parker Earth Moving Company’s (PMEC) foreign competition has caused the company to reduce market share. The percentage has declined from 47% to 29% and PEMC has suffered losses of 3%, 7%, and 11% in the last three years. Team B analyzes the current operations and activities of PEMC to determine the best way to achieve profitability. Business Process Recommendations Recovering losses and achieving increased profitability requires PEMC to implement several operations management principles. Beginning with redefining the organization’s vision and mission statement; internal stakeholders such as management and employees should acknowledge and work toward the organization’s objectives together. Managers can work collaboratively on creating a work breakdown structure, further clarifying primary tasks, and creating strategies for each business unit. A balanced scorecard can highlight each department’s key performance indicators, goals, and results. Implementing a work environment based on the Kaizen model for continual improvement encourages employees and managers to work on solutions rather than conflicts. Employees can help establish where and when production interruptions...

...“Volcanic and seismic events are major pieces of evidence towards proving the plate tectonics theory is valid” Discuss the extent you agree with this statement. Plate tectonics is the theory used to explain the structures of the earth’s crust. Direct and indirect evidence can show us what is beneath our feet, or the composition of the crust. Volcanoes and earthquakes are both natural hazards, however are two of the most precise pieces of evidence to explain what is really happening up to 6371 kilometres away. In 1915, Alfred Wegener set out evidence for Continental drift using studies of continents fitting and glacial deposits samples. He discovered a large scale horizontal movement of continents in geological time. Rock types was one piece of evidence when discovering continental drift. The age, discovered by radiometric dating of rocks and distinct characters were both seen on two separate pieces of land. Other evidence such as Fossils from a fresh water Dinosaur, known as the Mesosauraus, is found on South America and Africa, there is no way this dinosaur could have swam across the Atlantic to populate on both lands. Although there was plenty of evidence for Continental drift, there was no reason of why the continents would be driven apart and together. This was until 50 years later, when geologist Harry Hess proposed his hypothesis on Seafloor spreading. He predicted that basaltic magma from the mantle rises to create new ocean floor at the Mid-Ocean Ridges. Seafloor...

...Imagine this scenario set in the future. We know that a decently large rogue planet will be crashing into Earth in a certain number of years and we cannot do anything to stop this from happening. However, we do have the ability to terraform a planet. If we could also move humanity to either Mars or Venus, which one should we go for and why? Hi Jessica! Interesting question. To start off, I will define what terraforming is for those who do not know what it means. Terraforming refers to the hypothetical process of modifying a planet or other heavenly body in order to make it habitable by humans. This outcome can be achieved by changing the atmosphere’s competition, the body’s temperature, the surface topography or the planet’s ecology. In order for terraforming to be successful and the planet to be able to sustain life, NASA has defined that such a body must have extended regions of liquid water, favourable living conditions and enough energy sources to sustain metabolism (). Mars is generally understood to be the planet that is closest to fulfilling these criteria because in many respects it is the most Earth-like planet in the Solar System(). It is generally accepted by scientists that Mars once had an Earth-like characteristic including a thicker atmosphere and abundant sources of water. These characteristics have diminished over the course of hundreds of millions of years due to carbon dioxide/carbonates reactions, a lack of magnetosphere and numerous asteroid impacts. The...

...Task 1 (LO 1: 1.1 and 1.2) A tunnel is an underground or underwater passageway, dug through the surrounding soil, earth, rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in tunnel. Some tunnels are aqueducts to supply water for consumption or for hydroelectric stations or are sewers. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. There 4 kinds of tunnelling methods that is widely used. They are (1) Cut and Cover Tunnelling method (2) Drill and Blas Tunnelling method (3) Tunnel boring machine method (TBM) (4) Sequential Excavation Method Cut and Cover Tunnelling Method Cut and Cover Tunnelling Method Cut and Cover Tunnelling Method Cut and cover tunnelling is a common and well-proven technique for constructing shallow tunnels. The method can accommodate changes in tunnel width and non-uniform shapes and is often adopted in construction of underground stations. Several overlapping works are required to be carried out in using this tunnelling method. Trench excavation, tunnel construction and soil covering of excavated...

The atoms reside at the corners of cubes of side L = 0.200 nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken.

...PROJECT ANALYSIS OF PLANT PIGMENTS USING PAPER CHROMATOGRAPHY AND VISIBLE AND/OR UV SPECTROSCOPY (1-31-96) INTRODUCTION We have seen that all cells must constantly consume fuel molecules to maintain themselves, grow, and reproduce. Fuel molecules such as glucose constitute an immediate source of energy for biological work that can be released by catabolic cell processes. However it is necessary that life on earth have a constant source of energy that can be harvested and used to generate complex fuel molecules from simple starting materials. The ultimate energy source upon which all life forms depend is visible light from the sun. Light energy must first be transformed into chemical(bond) energy before it can be utilized by the living cell. This transformation is achieved only in the cells of green plants and certain bacteria. In green plants it is coupled with a transformation of matter in which relatively low-energy compounds, carbon dioxide and water, are converted into high energy chemical molecules that become subunits of carbohydrates. There are four different pigment groups present in leaves of photosynthesizing plants. Studies indicate that only the chlorophyll IS involved in the actual absorption of light energy and later conversion to chemical energy of living cells. The other pigments also absorb light energy, but it is transferred to the chlorophyll for conversion to chemical energy. Biochemists have developed a variety of methods for the purification and analysis of biomolecules...

...the way back to the Earth. All the astronauts, including two women died in this disaster. The reason why this disaster happened was a piece of foam insulation broke off from the Space Shuttle external tank which damaged the left wing of the shuttle. Even though some engineers of NASA had doubted that the left wing of shuttle had been damaged, the administration staffs restricted to do advanced research. The engineers of NASA found that the foam shedding and debris strikes could not be avoided and solved, even though the previous design of space shuttle required that the external tank was not to shed foam or other debris. However, this situation was not account for security threat and regarded as the acceptable risk. Thus, the launch was given the go-head. Due to the broken left wing which caused the damage of Space Shuttle thermal protection system, hot gases penetrated and destroyed the internal wing structure which led to the disintegrate of the shuttle immediately over the area of south Dallas. Ignore the Feedback Control Even though the similar situation happened in the prior mission (in the 13th and 16th mission of Columbia, the foam went undetected as well), the administration department of NASA were getting used to those situation which did not cause the serious damage to the shuttle that led to the disaster of the 28th mission of Columbia. Just like Diane Vaughan explained this phenomenon in her book as “normalization of deviance”. After analysis the disaster of shuttle...

...Human Expansion into Space Human population on earth has exploded over the past few centuries; it has gone from a small collection of hunters and gatherers to a globally connected race of over seven billion people. Even though humans have gotten so numerous and expanded so far, we are lucky to have gotten to this point at all. Earth is threatened all the time by events that could end the human race as we know it. Things like global war, famine, natural disasters, manmade disasters, asteroid hits, hostile extraterrestrial life, or other countless things that could bring an end to humans. Currently the entire population is on one planet, this means if one of these events come to pass humans could become extinct. With the threat of mass extinction imminent, the human race needs to expand past Earth and colonize other earth like planets in the Milky Way. With this expansion humanity is not just on one world and could survive after a disaster on earth. In order to expand scientists will have to solve three main problems: finding a planet suitable for colonization, the technology needed in this undertaking, and the political red tape. The first main problem in colonizing space is finding a suitable planet to colonize. According to (Villard, 2011) in “Hunting for Earthlike Planets,” there are several steps that scientists use to look for a planet with the possibility of supporting human life. The first and most important step is finding a planet within the goldilocks zone or habitable...

...1 RTVF 010 Hill1 5/8/14 Film Analysis Paper Assignment: The Avengers The Avengers is an outstanding movie with a storyline that makes it hard for the viewer to look away. It is about an evil man from another world, Loki, who comes to earth to steal an energy source of unknown potential, the tesseract, to try and take over the world. The leader of the earth’s peace keeping agency has went out and gathered The Avengers; a group of superheroes that consists of Iron Man, Captain America, Thor, The Hulk, Black Widow, and Hawkeye. Together these superheroes set out to save the world in a captivating story full of thrilling events. However, what makes these thrilling events come across to the audience so effectively is the excellent use of mise en scène. Throughout this movie, several aspects of mise en scène are used very effectively and are a big part of why this was one of the most succesful movies ever made. One scene that contains an extraordinary use of mise en scène is in the forest when Iron Man and Captain America first meet Thor. The first thing that stood out was the setting. These three extremely powerful forces are meeting for the first time in this very large forest. Right off the bat the setting gives off a sense that almost anything can happen. They are in the wide open wilderness with nothing stopping them from doing what they want to do. If they want to fight, they can do so without harming any nearby people. Another aspect of mise en scène that...

...Motivation I cannot trace back the moment when I first heard this statement that the more energy from sunlight strikes the earth in an hour than all of the energy consumed on the planet in one year but I wondered at that time, why are we having energy problems on earth. This was the start of fascination to look keenly into the problem of making alternate energy sources more practical. This fascination about renewable energy made me think more and more with open mind about the available large amount of energy which is gift of the nature to us. If we have made our life worse by not taking care of the nature then to use nature positively is the only way for us to save our planet. But I always wondered why we could not still use these sources for all our needs. But I knew if I had to go into the root of this thing, my aspiration should be coupled with the strong technical base and other necessary dependent aspects. In my third year I took course on “Renewable Energy” that gave me knowledge about different kinds of renewable energy systems. The course structure covered major part of it - Solar Energy, Wind Energy and Bio-Energy etc. And it was more like the base for my future endeavor. Fortunately having centre of Excellence in Energy in our college (Indian Institute of Technology Rajasthan) gave me several opportunities to get exposure of Energy field. In the 5th semester, The Centre of Excellence in Energy at IIT Rajasthan conducted a Renewable Energy Consortium in 2010 in which...
