Population Growth and Its Effect on Global Warming Research Paper

Population Growth and Its Effect on Global Warming - Research Paper Example , this brief essay will attempt to briefly analyze this monolithic problem in terms of the exponential growth in human population that has been evidenced over the past 200 years. Furthermore, a determination will be sought to be made with regards to the question of whether human action or natural causes best explain the climate fluctuations that planet earth has recently been chronicling. Lastly, as a function of the previous points of discussion and analysis, the author will attempt to proscribe a reasonable and performable set of steps and solutions which both the scientific community and the world at large could and should seek to employ as a function of ameliorating the stress on planet earth and the issues at hand. Furthermore, as a means of bringing such an understanding about, the analysis will also rely upon relevant scientific publications on the topic as well as verifiable statistics and charts concerning overall levels of climate change and corresponding increases in CO2 e missions by humans over the past several decades. However, noting the global climate change is an issue is not, in and of itself sufficient. As such, the analysis will also consider the rapidly increasing demand that fossil fuels have been projected to assume over the next several decades and posit a potential alternative to further environmental degredation at the hands of seemingly ever expanding human populations. Firstly, there is the point of view that strongly believes that the swings in climate change are the direct result of the presence of high amounts of human CO2 in the atmosphere that is causing a greenhouse effect on the planet and thereby causing world temperatures to rise. Prima fascia of this argument is the belief that human CO2 emissions are responsible for the changes to the global climate. It follows therefore that those which ascribe to this point of view are the most vehement that drastic and immediate changes to the manner in which human beings interact

Accounting is a process through which organizational reality can be communicated. Organization does accounting for the purpose of communicating realities towards the all stakeholders related with the organizations. Every organization has internal and external stakeholders. It is important for internal and external stakeholders to know the organization reality in detailed fashion. To get the detailed information there is no substitute of accounting. It indicates that accounting does communicate reality to the stakeholders. Financial communication is the most important factor on the basis of which investment related decisions are being made. Investors invest their moneys on the basis of proper information. That information is being communicated with the help of accounting. According to the framework of Burchell, if uncertainties of

The Policies of Alexander Hamilton and Andrew Jackson Essay

The Policies of Alexander Hamilton and Andrew Jackson - Essay Example He also has a high regard towards the upper-class and educated men as the fittest to become the country’s leaders. Opposing the political views of Hamilton is Jackson’s democratic-republicanism. He stressed out the ordinary people’s right to vote and the first president to represent all Americans, regardless of their social standing (â€Å"The Presidency†). He is known to be Hamilton’s critic who contradicts federalism ideals. He regarded Hamilton’s views as elitist and idealistic. Relationship to Modern America Today, the American Federal government is a combination of two political views. It takes Hamilton’s view on the independence of government branches and Jackson’s idealism on suffrage. States also are given freedom provided that they also follow the national law. In other words, today’s politics resemble both political views. First, the elitist perspective of Hamilton is still surviving, although discouraged by mod ern thought. Many of the politicians today are with high educational background and came from influential families. Second, Jefferson’s state independence is practiced. State leaders are given the freedom to revise existing laws or to make laws not found with the rest of the states (e.g. legal drinking age). Economic Views By the end of the American Revolution, the country has to face a tremendous economic problem. There is an estimated $54 million debt of the United States while it only has barely half of the amount as their asset (â€Å"Alexander Hamilton’s†). Clearly, there is a huge deficit in the country’s economic budget. To address this problem, Alexander Hamilton was given the task to regulate all forms of economic activities until it stabilizes. As young as he was at that time, he regarded taxation and debt management as a two-way street to economic stability. He proposed that all states should be imposed by appropriate taxes for debt payment. Al though states that are already debt-free at that time resisted against this proposal, it is still pursued and became successful. The next move by Hamilton was to establish the Bank of the United States as â€Å"modeled from the Bank of England† (â€Å"Alexander Hamilton’s†) to take care of the collected taxes. While concerned with the nation’s debt payment, unlike Hamilton, Jackson disagrees with imposing taxes on states and became an advocate of the Laissez-Faire economy. This means to say that states are free to make international economic relations and other local economic activities without the imposition of taxes or the intervention of the national government (Ambrose and Martin 33). Despite the success of Hamilton's implementation of taxes and debt management, Jackson believes that an economy is better off without the presence of both. Since his younger years, Jackson hated debt in general, more so with national debt (Smith).

Summary, Plot, Moral Values, Themes the Call of the Wild Essay Summary: Buck, the lead character, is a much loved and pampered dog living a comfortable life on a ranch under the loving care of his owner, a wealthy judge who makes his pet want for nothing. Then one day, Bucks life takes a dramatic turn when hes sold off by an unscrupulous servant to pay a debt. He travels in a cage for the first time and is sold in Alaska, where dog-sleds are the primary mode of transportation. Buck has to quickly adapt to his new life as a sled dog and learn how to survive in a dog-eat-dog world where the competition is tough and often deadly. The basic comforts he had hitherto taken for granted, namely abundant food and warm shelter, are replaced by the bare necessities for survival which have to be fought for tooth and claw. Buck learns quickly, his physique and natural intelligence standing him in good stead, all the while improving as a sled dog and ultimately deposing the pack leader, his arch enemy: Spitz. His life changes sharply yet again, as he is sold off to Hal and his wife, people who know nothing about sledding or caring for animals till at last he is rescued by a kind and loving man, his last master: John Thornton. At last Buck finds a master who loves him besides caring for or pampering him. However this happiness is not built to last, his master is murdered by the vicious Yee-Hats, a tribe of brutal savages. In the midst of his anguish, Buck has to find his true self, he has to listen to the Call of the Wild and to answer it to go leaping towards his destiny Get this e-book now at a very low price.

Valid until Sep 22, 2012 Social/Historical context: The book was published in 1903, the time of the gold rushes and adventures in vast, unexplored tracts of land. A time before the full use of machinery and sophisticated technology, when often, dog sleds and carts were the only means of communication in the wilderness. Londons masterpiece, as it is often hailed to be, explores the heart of those yet-primitive societies on the edges of civilization, through the minds of their beasts. Writing Style: The book is written as a third-person narrative, continually following the central character and from the point of view of the central character. The language is extremely simple and lucid, and combined with a gripping plot, the book is easy to follow and hence suited for younger as well as seasoned readers. London has explored society from a dogs perspective. However the deeper, darker messages of unbound greed, ambition and ultimately the necessity of adaptability to change are easy to spot. There is an innocence in the way the author has attempted to capture the scene from a dogs point of view, this adds to the simple charm of the book. My Thoughts: One of my early classics, I read this for the first time when I was 9 and I loved it because I loved animals as all children of that age do. Now, when I reminisce about it I relate, with an adult mind, to the other themes in the book. I cannot help but wonder at the complexity of the layers, so deep yet so simply structured. A timeless tale for all and sundry.

Purpose Of Compaction: Types Of Compaction

Purpose Of Compaction: Types Of Compaction Soil compaction is one of the most critical components in the construction of highway embankments, earth dams, foundations and many other engineering structure. Soil must be compacted to their unit weights, increase the strength characteristic which increase the bearing capacity of foundations constructed over them. Soil is compacted by removing air and water from its pore space. Compaction is a change in soil structure, not just an increase in soil density. Healthy soils have a diversity of pore sizes, while compacted soils have mostly small pores. In general, Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. Almost all types of building sites and construction projects utilize mechanical compaction techniques. During the compaction process soil partials are pushed closer together. This reduces the size of pores, the continuity of pores, and the size and stability of aggregates. Only under severe compaction will aggregates break down.This soil density chart shows properly compacted soil. Purpose of soil Compaction: The principal reason for compacting soil is to reduce subsequent settlement under working loads. Also in a construction material, the significant engineering properties of soil are its shear strength, its compressibility, and its permeability. Compaction of the soil generally increases its shear strength, decreases its compressibility, and decreases its permeability. in addition, compaction reduces the voids ratio making it more difficult for water to flow through soil. This is important if the soil is being used to retain water such as would be required for an earth dams. So we conclude that there are four reasons to compact the soil: Increase load-bearing capacity. Prevent soil settlement. Provides stability . Reduce water seepage, swilling and construction. Poor compaction can lead to unwanted results. Figure: result of poor compaction Types of compaction: There are four types of compaction that are commonly used on soil and/or asphalt: Vibration Impact Kneading Pressure Each of these types is carried out using one of two types of forces: static or vibratory. Static force relies on the weight of a machine to apply downward pressure on soil, thus compressing the soil particles. Adding weights to, or removing them from, the compaction machine can adjust the amount of pressure. Although effective, static compaction is best suited for the upper soil layers. The types of compaction that fall under static are kneading and pressure.Padfeet on a Caterpillar CP563 Vibratory force, on the other hand, uses mechanically driven force to apply downward pressure in addition to the weight of a machine. The mechanically driven force is an applied vibratory force that rotates the eccentric weight of a piston and spring combination. Compactors achieve compaction through the use of delivering rapid blows, or impacts, to the surface. This is effective in that it not only compacts the top layers, but the deeper layers as well. With vibration, the particles are set in motion and moved closer together to form a high density Compaction soil types: Different types of compaction are best suited for different soil types and conditions. This is because of the underlying density and moisture that different soil types are able to retain. Soil types are classified in three soil groups, with consideration to grain sizes. These types are: Cohesive Granular Cohesive and granular Cohesive In cohesive soils, such as clay, the particles contain characteristics that make them easily stick together so compaction can be achieved by high impact, which forces the air out of the particles, pushing them together. Granular Granular soils include sand, gravel, and other particles that typically range in size from 0.003 to 0.08 inches (0.008 to 0.2 cm). Because granular soils have good water-draining properties, they are able to obtain high density when fully dry or saturated. Granular is best compacted by shaking or vibrating the particles. Any type of vibratory equipment is best suited for this type. Depending on the type of granular soil, different degrees of vibration are required. Granular and Cohesive Often, soils are a mixture of both granular and cohesive, requiring more precise compaction equipment. Equipment should be chosen on the basis of the soil in the mix that is present in the highest percentage. Some materials, such as asphalt, require both vibration and static pressure to be compacted effectively. Machinery uses frequency and amplitude to apply a force for compaction. Frequency is the measure of the speed of the eccentric shaft rotation, or of the jumping of the machine, quantifiable by vibrations per minute (vpm). Amplitude measures the maximum movement of a vibrating body from its axis in one direction Field Tests: It is important to know and control the soil density during compaction. Following are common field tests to determine on the spot if compaction densities are being reached. Sand Cone Test (ASTM D1556-90): A small hole (6 x 6 deep) is dug in the compacted material to be tested. The soil is removed and weighed, then dried and weighed again to determine its moisture content. A soils moisture is figured as a percentage. The specific volume of the hole is determined by filling it with calibrated dry sand from a jar and cone device. The dry weight of the soil removed is divided by the volume of sand needed to fill the hole. This gives us the density of the compacted soil in lbs per cubic foot. This density is compared to the maximum Proctor density obtained earlier, which gives us the relative density of the soil that was just compacted. Nuclear Density (ASTM D2292-91): Nuclear Density meters are a quick and fairly accurate way of determining density and moisture content. The meter uses a radioactive isotope source (Cesium 137) at the soil surface (backscatter) or from a probe placed into the soil (direct transmission). The isotope source gives off photons (usually Gamma rays) which radiate back to the maters detectors on the bottom of the unit. Dense soil absorbs more radiation than loose soil and the readings reflect overall density. Water content (ASTM D3017) can also be read, all within a few minutes. A relative Proctor density with the compaction results from the test. How the Nuclear Density test works How the Sand Cone test works FACTORS AFFECTING COMPACTION IN THE FIELD: Compaction of a particular soil is affected by following given factors: MOISTURE CONTENT Proper control of moisture content in soil is necessary for achieving desired density. Maximum density with minimum compacting effort can be achieved by compaction of soil near its OMC (Optimum Moisture Content). If natural moisture content of the soil is less than OMC, calculated amount of water should be added to soil with sprinkler attached to water tanker and mixed with soil by motor grader for uniform moisture content. When soil is too wet, it is required to be dried by aeration to reach up to OMC. Moisture content of the soil is vital to proper compaction SOIL TYPE Type of soil has a great influence on its compaction characteristics. Normally, heavy clays, clays and silt offer higher resistance to compaction where as sandy soils and coarse grained or gravelly soils are amenable for easy compaction. The coarse-grained soils yield higher densities in comparison to clays. A well-graded soil can be compacted to higher density. LAYER THICKNESS The more the thickness of layer of earth subjected to field compaction, the less the energy input per unit weight of soil and hence, less is the compaction under each pass of the roller. Suitable thickness of soil of each layer is necessary to achieve uniform thickness. Layer thickness depends upon type of soil involved and type of roller, its weight and contact pressure of its drums. Normally, 200-300 mm layer thickness is optimum in the field for achieving homogeneous compaction. CONTACT PRESSURE Contact pressure depends on the weight of the roller wheel and the contact area. In case of pneumatic roller, the tyre inflation pressure also determines the contact pressure in addition to wheel load. A higher contact pressure increases the dry density and lowers the optimum moisture content SPEED OF ROLLING Speed of rolling has a very important bearing on the roller output. The greater the speed of rolling, the more the length of embankment that can be compacted in one day. Speed was found to be a significant factor for vibratory rollers because its number of vibrations per minute is not related to its forward speed. Therefore, the slower the speed of travel, the more vibrations at a given point and lesser number of pass required to attain a given density. TYPE OF COMPACTING EQUIPMENTS A large variety of mechanical equipments is available for compaction of soil but soil type and moisture condition will often dictate the type of equipments and method of use. Some important compacting equipment are given below: 1. Light compacting equipments (Rammers/Plate compactors) 2. Smooth wheel rollers 3. Sheepsfoot rollers 4. Pneumatic tyred rollers 5. Vibratory rollers 6. Grid rollers 2003 Dynapac CC122 Tandem Vibratory Smooth Drum Roller .

It is used for support of structural entities such as building foundations, roadways, walkways, and earth retaining structures to name a few. In general, the preselected soil should have adequate strength, be relatively incompressible so that future settlement is not significant, be stable against volume change as water content or other factors vary, be durable and safe against deterioration, and possess prop Refrances: Das, Braja M.
