Sustenance - Coursework Example All things considered, the vast majority should have a calories rate from starches of around 50 percent, and between 16-21 percent from protein and 30 percent from a fat source (Berni et al., 2008). Another significance is all out micronutrients consumption. Despite the fact that in little amounts, micronutrients are basic for various body capacities. An assorted eating regimen raises the likelihood that every one of your minerals and nutrients needs will be met (Collins, Myatt, and Golden, 1998). The last significance is hydration, which is a significant worry since our bodies contain around 60-75 percent of water, which is basic in transport, temperature guideline and supplements retention (Collins and Myatt, 2000). The outcomes show that proteins, fats and starches are the 3 significant macronutrients because of their jobs in the human body. They are the principle parts of our eating routine. Our bodies additionally require others supplements, for example, nutrients and minerals despite the fact that in a lot littler amounts. They are thusly alluded to as micronutrients. Each macronutrient has imperative capacities in the body (Kattelmann, 2006). Its primary job in the body incorporates assembling, keeping up and fixing body tissue. It’s strongly prescribed to truly dynamic people in light of the fact that their muscle tissue is in consistent need of fix. Different jobs of protein in the body are creation of catalysts and hormones, which perform fundamental capacities. Proteins are additionally used to help in the insusceptible procedure (Knivsberg, 2003). The primary capacity of fat is assurance among its numerous jobs in the human body. Protection for keeping internal heat level and assurance of body organs through padding are additionally elements of fat in the body. Fats advance development and improvement and keep up cell films. What's more, fats assume a crucial job in nutrient absorption. Nutrients A, D, E and K are fat solvent nutrients which imply that for them to be retained into the arrangement of the body; they need fats (Metheny et al.,

Word Count: 1486 The Differences in Lucy Salyer’s and Cybelle Fox’s Criteria For Citizenship All through American history, the United States government made approaches that concluded who can and can't come to America to be perceived as an undeniable resident: a person who has been perceived as a dependable individual from a country and gets benefits allowed by the administration. Lucy Salyer, creator of Baptism By Fire, and Cybelle Fox, creator of Three Worlds of Relief, stress that the legislature put together their movement arrangement with respect to issues, for example, race and occupation. Regardless of their understanding that the United States government assumed a significant job in concluding who can and can't turn out to be undeniable residents, Salyer and Fox differ on the fundamental models wherein they chose which workers could have this acknowledgment. Salyer contends that immigrants’ race and administration chose whether they ought to be incorporated or avoided from full citizenship, while Fox declares that individuals’ occupation decided this iss ue. As Salyer and Fox both referenced, the administration assumed a fundamental job on concluding who can become residents through enactment, composed gatherings, and legal decisions. The administration can be characterized for this situation as governing bodies, offices, and the equity framework. All through American history, lawmaking bodies made laws in which included and prohibited newcomers to America. Aristide Zolberg, creator of A Nation by Design, accentuates this by expressing, â€Å"nationality includes the depiction of a limit, meaning at the same time incorporation and exclusion† (Zolberg,17). A nation can will in general be inviting or unwelcoming to outsiders. In the United States, governing bodies have been comprehensive and selective to outsiders contingent upon the national intrigue. Lu... .... 56% of laborers were secured, while 67% of them were Europeans and 57% were white. As indicated by Fox, Europeans profited the most since dominant part of them held assembling employments and were bound to turn sixty-five when it was grandfathered in. However, roughly 38% of Mexicans and blacks were secured. This was because of most of them being rural laborers or household laborers. Hence, Europeans held occupations that permitted them to meet the rules for government managed savings benefits, while Mexicans and blacks didn't (Fox, 251-253). Salyer and Fox concur that the legislature assumed a job in forming migration during the 1920s and 1930s. However, they can't help contradicting the models that the administration used to choose who got undeniable citizenship. This discussion despite everything proceeds with today and this country keeps on putting together a models with respect to who to incorporate and reject.

Or just slightly late for Chanukah. Or just right in time for Kwanzaa. Or just under the wire for Festivus. Or over a month too late for Wookie Life Day (check out our new Star Wars infographic). Unwrap the video below!Our first question was about the movie Elf, and how much Will Ferrell turned down, rather than make a sequel to the modern Christmas movie classic, Elf. The answer? $29 million. Your humble Know Money, Win Money host would do it for even half that! Will Ferrell is currently appearing in Daddy’s Home 2, which seems to take place at Christmas, and we can only assume, is essentially an Elf sequel. Sure, we haven’t seen it yet, but unless there’s a line where the characters explicitly let you know that they aren’t secretly elves, we feel pretty comfortable asserting that they are. Our next question asked about the number 462,000. Specifically what that number means in dollars each holiday season. While you might think it’s the amount Americans spend on Christmas trees or eggnog, in the end, it could be only one thing: a song about one thing. And that what one thing is what Mariah Carey wants for Christmas. Yes, “All I want for Christmas is You” makes over $450,000 in royalties each holiday season, which actually seems a little low for a song that plays nonstop from the end of November through the unwrapping of the last gift of the year.

The Future of Nuclear Energy Abstract Climate change is a threat to the entire planet. The increase in global temperature is significantly altering our planets climate, resulting in more extreme and unpredictable weather. Greenhouses gases, such as carbon dioxide, trap heat in the atmosphere and regulate our climate. Don’t waste time! Our writers will create an original "Possible Future of Nuclear Energy" essay for you Create order These gases exist naturally, but humans add more carbon dioxide by burning fossil fuels for energy and by clearing forests. Humans have sped the climate change process by relying on fossil fuels for a long time now. It is necessary to shift the focus to more sustainable source of energy. The shift to renewables is a long-awaited transition in the history of mankind. The transition always made sense, but there are innumerable factors- economic, social and political which make this transition difficult. The renewables also have some technological concerns which make the transition difficult. One clean energy resource has been making progress slowly and steadily which could help smoothen the transition and solve the current problems faced by solar and wind, is nuclear fusion energy. The problem with this source of energy is the bad image in public, which makes it difficult to regulate it for the policy makers. This paper attempts to explore the future of nuclear energy amidst the uncert ainty of renewables and ignorance of the advantages of nuclear fusion energy. Introduction The global temperatures are rising constantly. It leads to melting of glaciers and increase in ocean water level. The world has seen more hurricanes in this decade than in past century. The intensity of the natural calamities is getting severe with each passing year. This results in endangering the species and leading them for their extinction, animals find it extremely difficult to adapt to these drastic changes. The devastation by these natural calamities has left the mankind wondering about their mistakes. A large portion of the educated masses are aware of the disaster that is waiting for the mankind if not immediate steps are taken, whereas few ignorant souls are unaware. Many scientists have given up on the positive outcome of climate change, few estimate that we have less than 40% chance to survive this disaster. It is the need for the future that global community be united under one roof and regulates strategies to fight the climate change. World treaties and Paris agreement The world has come together before multiple times to try globally. The first time a global treaty was signed was in 1987 called the Montreal Protocol, which required all nations to phase out CFCs, a chemical used in refrigerators and air conditioners that was munching through our ozone layer. It imposed hard targets for phasing out CFC and it was legally binding. Also, it took into consideration the developing countries by making special allowances for them, so that the initiative is not a hindrance for their progress. That treaty was a huge success, saving the ozone layer. This led to the world leaders to think that climate treaty on a global level could help fight the climate change. The Paris agreement is not the first climate treaty signed by the global community. It all started with the 1997 Kyoto Protocol, a treaty that split the world into developed and developing countries and the roles for the agreement was divided as per that classification. It binded the developed countries to cut their emissions and developing countries were given leeway to develop their economy. It ended being a complete disaster as the developed countries felt unfair about changing their ways whereas developing countries, grew so fast that they emitted more than what developed countries could stop. After that, in Copenhagen 2009, UN negotiators tried to craft a successor treaty to Kyoto that would require all countries, rich and poor, to make legally binding commitments. But that didnt work, either. After the failed climate treaties, it was important to decide a format which would work. we have reached at a stage where if global efforts are not taken, the planet is destroyed. The Paris Agreement central aim is to strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius. Every country must try to help fight the climate change and make a serious commitment towards reduction of carbon emissions. The agreement, not being legally binding this time was the strength of this agreement. Every country would start by submitting an entirely voluntary pledge for how it planned to address climate change. The content would be up to each individual government, to decide what works for them economically and technologically. This allowed the nations to have an individual plan without the legal o bligations being forced on it. Since every country had different priorities, this approach also allowed countries to tailor their climate efforts to their own individual circumstances. China could focus on air pollution and India could focus on electricfying its villages with solar power. The idea is that cooperation and political persuasion can achieve what the quest for a binding treaty failed to do. Climate change and carbon emissions The levels of carbon emissions have been increasing rapidly for the past decade. The problem with CO2 is that it stays in the atmosphere for long periods of time. As a result, even if emissions stopped increasing, CO2 concentrations would continue to increase and remain elevated for hundreds of years. Moreover, if we stabilized concentrations and the composition of todays atmosphere remained steady, which would require a dramatic reduction in current greenhouse gas emissions, surface air temperatures would continue to warm. This is because the oceans, which store heat, take many decades to fully respond to higher greenhouse gas concentrations. The oceans response to higher greenhouse gas concentrations and higher temperatures will continue to impact climate over the next several decades to hundreds of years. Last year, the CO2 levels crossed the threshold of 400 ppm and it is increasing every year. The IPCC has marked that beyond 450 ppm would be a catastrophic carbon dioxide level i n the atmosphere. It is extremely important to control the rising emissions. There is on-going research on carbon capture and storage, which would help control the rising emissions. Ideal solutions for climate change There are multiple solutions to fight climate change and all of them point towards the transition to renewable energy. It is important to stop the use of fossil fuels to keep the carbon emissions in check. Fossil fuels provide substantial economic benefits, but in recent decades, a series of concerns have arisen about their environmental costs. A few developed countries have implemented policies to limit fossil fuel consumption through a mixture of taxes, fees, or regulation on carbon emissions and subsidies for energy conservation and the development of low- or no-carbon energy resources. (Covert, Greenstone, Knittel, 2016) There are multiple positive steps taken in this direction to move towards the renewable energy on a global level. California is proposing to reach 60% renewable energy by 2030; 176 countries have clean energy goals. Hawaii, Americas most oil-dependent state, has pledged to be 100% renewable by th middle of the century. There is a raging debate whether 100% renewables are realistic and feasible. Multiple studies have been made and there is on-going research for both the sides. The optimists argue that it will be more cost-effective than the current system, which largely relies on fossil fuels. The researchers say that the existing renewable energy potential and technologies coupled with storage can generate enough energy to meet the global electricity demand by 2050. The pessimists say that was important to push back against the 100 percent argument because they fear political blowback could undermine the goal of reducing emissions far enough and fast enough to keep global temperature s from rising more than 2 degrees Celsius. The term negative emissions is relatively new in the climate change debate. It has been used to describe activities that recover more carbon from the environment than the produce and dispose of it in a safe and permanent form. Without negative emissions technologies it will get progressively more difficult to stop climate change in time. Negative emissions technologies combine capture or extraction of CO2 from the environment with carbon storage. Negative emission technologies can be deployed for canceling out concurrent positive emissions, or they can be used to reduce the carbon content of the atmosphere. Of course, if the world is emitting more CO2 than it recaptures from the environment, a negative emission, even if it is not dedicated to removing a concurrent emission, will only lower the rate of increase, rather than creating a net negative emission. (Anderson Peters, 2016) There are efforts which can be taken on an individual level like energy conservation efforts at home and work. An energy efficient lifestyle can be adopted which would help save energy. Electrical equipment can be unplugged when not in use. The shift to LED lighting can help conserve energy and save money. Biking or walking to work or other walkable areas or carpooling to work can save the emissions by automobile. The need for nuclear energy The question arises from the above discussion that there is no mention of nuclear energy as an ideal solution to climate change and stop carbon emissions, then why should the world be concerned about the future of nuclear energy? Where does the need of nuclear energy arise? The priority for the planet is to stop net emissions of greenhouse gases, especially carbon dioxide. Putting too much emphasis on wind, solar and other renewables may block off better carbon-reduction paths. After decades of investment, it is wrong to leave nuclear power off the table. Carbon emissions in Germany rose because it chose to phase out nuclear power and so burned more coal. Major electricity generation is done by coal, natural gas and petroleum- all fossil fuels. If we aim to forgo fossil fuels, how will we meet the electricity needs of the country? Nuclear may not be an ideal solution but it is carbon neutral and it meets 20% of the electricity needs of US. The reason world keeps falling back to fossi l fuels is because they are reliable, cost-effective, but they also lead to a lot of carbon emissions. Carbon emissions is something that the world cannot afford. Nuclear powers track record of providing clean and reliable electricity compares favorably with other energy sources. Wind and solar power are becoming increasingly widespread, but their intermittent and variable supply make them poorly suited for large-scale use in the absence of an affordable way to store electricity. Hydropower, meanwhile, has very limited prospects for expansion in the United States because of environmental concerns and the small number of potential sites. Concerns about climate change and air pollution, as well as growing demand for electricity, led many governments to reconsider their aversion to nuclear power, which emits little carbon dioxide and had built up an impressive safety and reliability record. Some countries reversed their phaseouts of nuclear power, some extended the lifetimes of existing reactors, and many developed plans for new ones. But the movement lost momentum, when a 9.0-magnitude earthquake and the massive tsunami it triggered devastated Japans Fukushima nuclear power plant. The event caused widespread public doubts about the safety of nuclear power to resurface. Type of nuclear energy The foundation of nuclear energy is harnessing the power of atoms. Nuclear fission takes place when a large, unstable isotope, atoms with the same number of protons but different number of neutrons, is bombarded by high-speed particles, usually neutrons. These neutrons are accelerated and then slammed into the unstable isotope, causing it to fission, or break into smaller particles. During the process, a neutron is accelerated and strikes the target nucleus, which in most of nuclear power reactors today is Uranium-235. This splits the target nucleus and breaks it down into two smaller isotopes three high-speed neutrons, and a large amount of energy. This resulting energy is then used to heat water in nuclear reactors and ultimately produces electricity. The high-speed neutrons that are ejected become projectiles that initiate other fission reactions, or chain reactions. (Duke energy, 2013) Fusion occurs when two smaller atoms collide at very high energies to merge, creating a larger, heavier atom. This is the nuclear process that powers the suns core, which in turn drives life on Earth. Fusion reactions have an energy density many times greater than nuclear fission and fusion reactions are themselves millions of times more energetic than chemical reactions. (Vaillancourt, Labriet, Loulou, Waaub, 2008) The reasons that have made fusion so difficult to achieve to date are the same ones that make it safe. The point to be noted about Nuclear Fusion plants are not like Nuclear Fission plants aka the nuclear plants we use today and it will not melt down. Let us take a magnetic confinement reactor, these reactors work by using magnetic fields to squeeze plasma in a torus (donut-shaped chamber) so that reactions can take place. If the confinement somehow failed and the magnetic fields disappeared, the plasma would simply just expand and cool and the reaction would literally just stop and nothing more would happen. There is no scare of a possible melt down even in a worst-case scenario. The only problem with Nuclear Fusion is that it is difficult to accomplish since its incredibly messy. While its relatively easy to split an atom to produce energy, fusing hydrogen nuclei is a couple of orders of magnitude more challenging. To replicate the fusion process at the core of the sun, we must reach a temperature of at least 100 million degrees Celsius. There are a few risks involved with fusion energy, but they are minor as compared to the fission energy plants. The tremendous energy gain inside the vessel is one of the largest risks of fusion, however, a lot of care has been taken in selecting materials, which will be used to fabricate the vacuum vessel and other plasma facing components to minimize the activation caused by neutrons. Another potential issue is with the storage of tritium, one of essential materials. Since it is a short-term radio-active material, permission from international regulatory body for production and storage of Tritium is essential. Technological issues Tokamak reactors use a doughnut-shaped ring to house heavy and super-heavy isotopes of hydrogen known as deuterium and tritium. The studies show that it takes 50 megawatts of heat to generate 500 megawatts of electricity in a tokamak. Over 200 experimental tokamaks have been built worldwide, but to date they have all consumed more energy than they produce. A massive international tokamak project, the International Thermonuclear Experimental Reactor (ITER), aims to turn that situation around. The ITER is designed to produce 10 times as much energy as it takes to run, becoming the first ever net energy producing fusion reactor. ITER is collaboration of more than 35 countries around the world. The ITER members are now actively fabricating and shipping components to the ITER site in France for assembly. It is currently being built in the south of France, but with the first fusion experiments scheduled for 2030. MIT is also developing new technology like ITER but would give quicker results by 2022 or earlier. While tokamaks and stellarators use magnets to confine plasmas, another body of research is focusing on a different strategy to trigger fusion reactions, using high-powered lasers. There are multiple researches going on for nuclear fusion energy and it could be a reality within next 10 years. (Vaillancourt et al., 2008) Social issues The 2011 Fukushima-Daiichi nuclear plant disaster in Japan was a watershed moment for nuclear in Europe, with Italy deferring and subsequently cancelling new nuclear construction projects, and German Chancellor Angela Merkel kick-starting the countrys energy transition, of which phasing out of Germanys civil nuclear fleet is a key component. The event caused widespread public doubts about the safety of nuclear power to resurface. In the United States, an already slow approach to new nuclear plants slowed even further in the face of an unanticipated abundance of natural gas. Any reduction in nuclear generation will increase fossil fuel generation and pollution, given the low capacity factors and intermittency of solar and wind. Germany is a case in point. Its emissions have been largely unchanged since 2009 and increased in both 2015 and 2016 due to nuclear plant closures. Reports show that despite having installed 4% more solar and 11% more wind capacity, Germanys generation from the two sources decreased 3% and 2% respectively, since it wasnt as sunny or windy in 2016 as in 2015. And where France has some of the cheapest and cleanest electricity in Europe, Germany has some of the most expensive and dirtiest. At the same time, new reactors under construction in Finland and France have gone billions of dollars over budget, casting doubt on the affordability of nuclear fission power plants. Public concern about radioactive waste is also hindering nuclear power, and no country yet has a functioning system for disposing of it. In fact, the U.S. government is paying billions of dollars in damages to utility companies for failing to meet its obligations to remove spent fuel from reactor sites. This change in public perception has led to construction delays and cost overruns that have interrupted the principal nuclear states attempts to lead a nuclear revival. Businesses involved in nuclear power try to create new interests by, for example, exporting nuclear plants, fuel and related technology. These new interests mean that nuclear vendors become a new promoter of nuclear power, thus strengthening existing supporters. This allows the nuclear industry to expand and create links with other industries, and in these circumstances, the relevant government agencies are likely to continue to support nuclear power and the advancement of related technology. Majority of the public is unaware about the nuclear fusion and its benefits. A survey conducted by the students at University of Texas, Austin shows that the public opinion on nuclear energy is highly changeable and easily influenced, because most Americans do not feel well informed about the subject. Public opinion about nuclear energy reflects a tradeoff people make between perceptions of need and safety concerns.The percent of well-informed audience was only 21% and among them 54% were in favor of nuclear energy. If the percent of well-informed audience is that low, the results of the survey will be based on the opinions of people who have no idea about the facts and base their opinions on the things they hear from someone. It is important for the masses to be educated in technological progress of nuclear fusion, its advantages and risks involved so that a well-informed decision can be made. The current scenario does not affect the lives of the masses directly in the developed cou ntries, where electricity is cheap for now, they have jobs. It takes deeper awareness to realize the impending doom that the world is facing. One of the biggest challenges that we are facing is creating awareness about the available technology. Its important to create a society which is well-informed and take logical decisions based on facts. Political issues After Fukushima, the U.S. Nuclear Regulatory Commission, an independent federal agency that licenses nuclear reactors, reviewed the industrys regulatory requirements, operating procedures, emergency response plans, safety design requirements, and spent-fuel management. The NRC will almost certainly implement many the resulting recommendations, and the cost of doing business with nuclear energy in the United States will inevitably go up. Those plants that are approaching the end of their initial 40-year license period, and that lack certain modern safety features, will face additional scrutiny in having their licenses extended. (Vaillancourt et al., 2008) Despite these limitations, there is a clear revival of nuclear energy in long-term projections to fill an important part of the gap between the current capacity and the future energy needs of developing countries without increasing GHG emissions. The fastest growth would be in Asia. Many countries are investing in nuclear research and development, encouraging the current or future penetration of new nuclear technologies. The ITER project seeks to demonstrate the scientific and technological feasibility of fusion energy by building the worlds largest and most advanced tokamak magnetic confinement fusion experiment. ITER is the largest scientific cooperation project ever established, bringing together 35 nations representing more than half of the worlds population and 85% of the planets gross domestic product. The contribution of the seven ITER Members is done essentially in-kindChina, the European Union, India, Japan, Korea, Russia, and the United States have each established a Domest ic Agency that contracts with the industry to manufacture machine components and installation systems. Except for the European Union, each Members contribution represents approximatively 9% of the total value of the project. As host Member, the European Union not only procures its share of components and systems; it is also responsible for delivering the 39 permanent buildings of the installation, which brings its contribution to approximately 45%. Building ITER is also a demonstration that nations, when confronted with a global challenge, can establish a completely new model for international collaboration. ITER marks both the culmination of six decades of international scientific and technological effort and the opening of a new and decisive chapter in the history of fusion research. By demonstrating the feasibility of fusion energy, ITER will answer the question that has obsessed three generations of physicists and engineers. This collaboration sets a huge milestone on internatio nal level, which is one of the longest running experiment in the wake of this global crisis. This is making a slow but steady progress. (Bigot, 2017) The road map to the future Renewables are not ready to store the energy and thats why the paper pitches the idea of using nuclear fusion to bridge the gap between the demand and supply without falling back to fossil fuels. It could be argued that nuclear fusion is also in its experimental stages, whereas renewables at least have made some headway in the technology, then how does the argument make sense. I would like to stress that even though nuclear has been in experimental stage, it is being actively pursued and is slated to make its run by 2030. The renewables on the other hand have been satisfied with its progress for now and is still evaluating the idea of PV with storage facilities. The actual implementation will take years of research before it can be a reality. The research process for nuclear fusion have been going on for some time now and its ready to test its results. With the U.S. federal budget under tremendous pressure, it is hard to imagine taxpayers funding demonstrations of a new nuclear technology. But if the United States takes a hiatus from creating new clean-energy options, be it nuclear fusion, renewable energy, advanced batteries, or carbon capture and sequestration, Americans will look back in ten years with regret. There will be fewer economically viable options for meeting the United States energy and environmental needs, and the country will be less competitive in the global technology market. Conclusion The greenhouse gases accumulate in the atmosphere, finding ways to generate power cleanly, affordably, and reliably is becoming an even more pressing imperative. Nuclear power is not a silver bullet, but it is a partial solution that has proved workable on a large scale. Countries will need to pursue a combination of strategies to cut emissions, including reining in energy demand, replacing coal power plants with cleaner natural gas plants, and investing in new technologies such as renewable energy and carbon capture and sequestration. The governments role should be to help provide the private sector with a well-understood set of options, including nuclear power, not to prescribe a desired market share for any specific technology. (Bigot, 2017) These are not easy steps, and none of them will happen overnight. But each is needed to reduce uncertainty for the public, the energy companies, and investors. A more productive approach to developing nuclear power, and confronting the mounting risks of climate change†is long overdue. Further delay will only raise the stakes.

In An Always Changing World, Technology Has Transformed

In an always changing world, technology has transformed from a casual use to an everyday usage. Ten years ago, in early childhood, children experienced what true peer interaction actually entails, but now they are communicating through iPads, or online games. Parents and guardians need to become more aware of the risks technology presents to children. Since the upcoming generation is overly dependent on technology, communication skills have decreased, and a family technology plan is needed for children 12 and under in order to develop vital aspects of the child’s life.

A Journey into Rolf’s Repressed Self Free Essays

When assigned to read the short stories in class to summarize and learn to paraphrase, there was one story in particular that emotionally touched me. This short story was â€Å"And of Clay Are We Created† by Isabell Allende. I found many great points that could be discussed about the story, and that is why I chose it to be a part of this research paper. We will write a custom essay sample on A Journey into Rolf’s Repressed Self or any similar topic only for you Order Now This story is a touching momentum of a man’s penetrating awakening that he no longer has to suffer from the emotional torment that was inflicted upon him during is childhood. Rolf, â€Å"like a flower sinking into the mud† (367) has sank into himself; a self that is magnetized with cataclysmic devastation and desolation. The volcano has erupted to bring an avalanche of despair, so does this same volcano explode, bursting to eventually bring calm and equanimity. Isabell Allende has Rolf Carle, a news reporter fly out to the devastating scene where you are introduced to Azucena, a young girl, stuck in the mud. Rolfe Carle stays with Azucena in hopes of saving her from this catastrophe but in the meantime, he Journeys through his repressed childhood memories. It is important to investigate repressed memories so you could courageously move forward to live a fuller life, instead of blocking these memories and living in the past. This paper will slightly take you through Rolf Carle’s emotions, the effects these memories can have, and how to overcome them. I found it ironic how Rolf Carle is close to many people’s histories when investigating the incident being a reporter but he is so distant with his own and we see this when he is telling his stories to Azucena. Rolf connected with Azucena at a level of experience, whether it was physical or emotional, they became one and shared hings with each other, some things being on a different level. This connection occurred because Rolf saw himself like Azucena â€Å"trapped in a pit without escape, buried in life, his head barely above ground† (Allende, 363). It is apparent that Rolf, like the buried and trapped girl, has submerged his own suppressed and hidden visceral terror; terror concealed from reality, that when it is unearthed, it is â€Å"intact and precise as if it had lain always in his mind, waiting† (Allende, 362). Like the deceased relatives who weigh down Azucena by clinging on her legs, so too is Rolf eighed down, incapacitated and paralyzed by the hauntingly vivid repressed memories. Rolf seemed to be trapped in pain as Azucena was in the mud, and confronting the thoughts of the girl dying was tough. Azucena taught him to pray, and eventhough it might have been consolation for herself, she later provides support for Rolfe when he was suffering through his past memories. This moment with Azucena, showed Rolf now to contront his own pains and memories, memories t I d witn humiliation, shame, fear, and regret. Rolfs emotional break down, as displayed with Azucena, resulted in him rising above the vultures and helicopters†¦ flying] above the vast swamp and corruption† (366). The question of importance and focus is not how this took place. In other words, it is not the line of successive actions and conversations, told and untold, that led to his decisive moment of freedom that is important. It is the cognitive and emotional process of a child who has been abused and chooses to either suppress or repression those traumatic painful memories. Indeed Rolf goes through a transformative change. But for 30 years he has â€Å"lived† or choose to forget certain events that took place in his life. The reader is never told in ull detail the abuse that was inflicted upon Rolf. We are given the illusion of a being beat with a belt then put in a closet. Such a painful event indeed was resulted in the present moment of physical pain, as well as, the present and future psychological damage done to Rolf, not mentioning the effects that it had on his sister. We are reminded time and again by survivors of abuse that emotional abuse is far worse because â€Å"the body is meant for recovering and healing physical wounds, the evidence is in scars, but the mind has a difficult time reacting to emotional abuse ecause it is counterproductive and counter intuitive in an unhealthy and unnatural way’ (abused victim who chooses to remain anonymous). When dealing with painful events, especially when occurring during childhood, a child often times chooses to either repress or suppress the memories hoping that he or she will never have to relive that moment. â€Å"A repressed memory, according to some theories of psychology, is a memory (often of a traumatic nature) of an event or environment, which is stored by the unconscious mind but outside the awareness of the conscious mind† (pyshowiki), whereas, suppressed memories are those memories hat are forgotten by choice. The question now becomes did Rolfs unconscious mind repress the memory or was it by choice that he suppressed his childhood experience? The answer first comes with an understanding that â€Å"memories stay in the brain for life† (Martin Dak). It is important to understand that â€Å"repressed memories do not disappear† (changingminds. org). â€Å"We can only bury memories for so long before they resurface† (Effect on the Mind). A person tends to â€Å"forget memories† because the fear of facing reality has invaded his or her life and he or she no longer has the fortitude o properly be engaged in the present moment. Like an earthquake that shatters glass into millions of pieces and demolishes massive infrastructures into complete and utter ruin; so too can the effects of repressed memories play in a person’s life. If repressed memories are not received, accepted, and properly discussed, a lifetime of tortured reality can unfold in a person’s life. We don’t have to look any farther than the 30 years of life that Rolf lived. The reader is never given a glimpse into his life after the abuse. We are told he has a relationship with a girl and that he is a reporter. Only with extremely caution, lest we stereotype that all reporters and journalists nave been through emotional hazards during their childh , but one nas to conclude that his Job does keep him moving from one situation to the next, avoiding having to ever think about his own issues and life. People that have repressed memories could possibly have disorders like post- traumatic stress disorder, anxiety, and depression. â€Å"Dwelling on such emotions†¦ is overwhelmed by extreme mental trauma (Novella). One could also experience traumatic amnesia, â€Å"this involves the loss of memories of traumatic experiences† (Kolk). How to cite A Journey into Rolf’s Repressed Self, Papers

The Principle Events In The Evolution Of The Earths Atmosphere Essays

The Principle Events In The Evolution Of The Earth's Atmosphere The Principle Events in the Evolution of the Earth's Atmosphere The literal translation of the word atmosphere is sphere of vapors. The Earth's atmosphere is a protective sphere of vapors, or air that surrounds the Earth and provides it with a layer of insulation from the harmful rays of the sun. It is a vital part of the Earth, and has changed dramatically since the beginning of time. The earth's atmosphere has gradually changed since the Earth's birth approximately 4.6 million years ago. In the beginning, the Earth's composition was very different that how it exists today. A long time ago the Earth's atmosphere was very similar to today's Venus and Mar's atmosphere. It had about 95% carbon dioxide, 2-3% nitrogen, and very little, less than 1% oxygen. Today the Earth contains 79% nitrogen, 21% oxygen, and 3% water vapor. It is evident that there were many events that happened over billions of years that have contributed to this change in the Earth's atmosphere. The Earth had developed so drastically because of the tremendous dust and gas cloud within the Milky Way galaxy. The Earth grew larger as huge meteorites hit it, and the surface was covered with dust. Volcanoes began to form and emitted lava, ash, and most importantly gases. Carbon dioxide, water vapor, and nitrogen were released into the atmosphere from the volcanoes. This process is called outgassing, and took place within the first million years or so of the Earth's formation. Then, about 4 billion years ago, the planet cooled, and the outgassed water vapors condensed into clouds. It rained and produced the oceans, and even enough to cover 95% of the Earth. In addition, because it rained, there was less carbon dioxide in the atmosphere. The carbon dioxide was lost over billion of years, as the ocean formed there was a chemical reaction in which carbon dioxide and water formed carbonic acid. It is shown in the equation CO2 + H2O = H2CO3. The carbonic acid dissolved oceanic rock into sand, silt, and mud. It is evident because of this geochemical process occurred there is more carbon in the rocks and minerals and there is less in the Earth's atmosphere. The Earth's first ever oxygen emerged about two millions years ago because of ultraviolet radiation. The water in the Earth's atmosphere was split into oxygen and hydrogen because of the ultraviolet radiation from the sun. The equation for this process is UV-* 2H20 -* 2H2 + O2. The first ever oxygen is from the ultraviolet radiation that occurred in the Earth's atmosphere. It is interesting to note that 600 million years ago only about 1% of the Earth's atmosphere was oxygen. Significant quantities of oxygen did not begin until plants arrived on the scene. The percentage of oxygen increased when plant life evolved and photosynthesis began to happen on the Earth. The first ever plants were blue-green algae, which lived the Earth's oceans. Plants used sunlight, water, and carbon dioxide to make their food in a process called photosynthesis. The process of photosynthesis can be easily seen in the equation 6CO2 + 6H2O = C6H12O6 + O2. The plants breathe in carbon dioxide and then release oxygen during photosynthesis, within 500 million years oxygen was the second largest part of the atmosphere after nitrogen. As oxygen became a greater part of the atmosphere the ozone shield emerged. The shield was formed when solar ultraviolet radiation forces the reaction for oxygen to form ozone, also known as 03. The ozone protects the Earth and it's inhabitants from the harmful radiation from the sun. In conclusion, the Earth's atmosphere has changed dramatically since the Earth's origin about 4.6 billion years ago. There are many factors that contributed to this change over time. By getting a better understanding of our Earth's atmosphere we can use in many useful ways. We can use this knowledge of the atmosphere for a worthy cause in many areas of science and greatly benefit from it. Science
