Renewable Energy Resources and their Limitations Essay

Curiosity and desire have led man to the peak of material progress. Discontent has always prompted him to change his environments and living conditions. Change is fundamental law of life for no change no progress. The more the peoples of the world have tried to change and ameliorate and better their lot, the more they succeed. The magic wand behind the spectacular and sustained progress has been the scientific technology. When we survey the achievements of men in their historical perspective; we get a clear idea about technological development from the earliest days from simple to sophisticated. The Present era is the era where energy is the basic resource which is essential for living. The present age can easily be termed as Fossil Fuel†¦show more content†¦Renewable Energy Resources and their Limitations: It is commonly believed that world can fulfill easily through renewable sources of energy if the present energy resources are consumed completely. This is not true. It is estimated that renewable energy resources like wood fuel, farm wastes, solar heat etc. would be able to fulfill only 7 to 15% of the world’s energy requirements. The remaining resources i.e. wind and water power can only fulfill a very small percentage of energy needs while for solar energy, expensive infrastructure is required. Solar Energy As far as the solar energy and its usage are concerned, one major area is installation of photovoltaic solar panels, which will cost more than a consumer, can save in the form of electricity tariffs. However, a collaborative research that was conducted by the professors of University of Ferrara and Bologna revealed that the use of domestic solar PV panels can save up to 2000 kWh per square meter of energy and can work effectively for a period of 20 years. The following table gives a cost comparison of different energy resources.

My Long March Essay Example For Students

My Long March Essay The Critique of My Long March Lang. 3750 100 Dr. Xiaojun Wang The Critique of My Long March In my class, on July 1st, we watched a movie titled, My Long March, which was filmed in mainland China. This movie employed 110,000 crew/actors and spanned over 6,000 miles of the historical Red Army route. This movie was made in order to commensurate the Seventieth anniversary of the Long March. This film was directed by Zhai Jungie and produced by August First Film Studio in 2006. Zhai Jungie directed an earlier film titled, Axis of War, and My Long March is intended to be a continuation of the storyline. The leading actors in the movie were Zhong Qiu, Wang Ying and Wang Jia. This movie won the Golden Rooster Award for best supporting actor and was nominated in 6 other categories. The story centers around a boy of 13, named Wang Ruir and his memories during the Long March. The movie shows the travels of the Red Army, the loss of his father, sister and brother-in-law during the saga. The movie depicts the relationship between Wang Ruir and military leader, Mao Zedong who is credited with saving the young boy’s life and guiding him tenderly throughout Wang Ruir’s journey into his teenage years. The film is a memoir of Wang Ruir’s and China’s losses during these turbulent times in the country’s history and the perseverance of the Chinese people. Since this movie was intended to commensurate the 70th anniversary of the Long March, many figures, settings and conflicts were based on the true history of China. According to Encyclopedia Britannica the migration of the soldiers was historically correct as the â€Å"communist troops crossed 18 mountain ranges and 24 rivers to reach the northwestern province of Shaanxi†. In addition, the troops were depicted in a very heroic manner which in turn, inspired many young Chinese to join the Communist Party. The movie is set to occur in the 1930s, and the Long March resulted in the move of the communist revolutionary headquarters from southeastern to northwestern China. The geography of the region was filmed very accurately by the director, who followed the real path of the Long March, hence, it contained the real mountains, rivers, and valleys. The costumes were designed fairly authentically using a lot of gray colors and simple designs for the peasants and workers in order to truly show how they lived during this time period. The other props in the movie such as weapons, tools and the lack of heavy artillery depicted the setting in a very realistic manner. In addition, it portrayed the devastation of war on the land and depicted the human suffering in a very lifelike way. I found this film to be very intriguing and it kept my attention throughout the story. It was informative and taught me a lot about Chinese customs, sounds, its people, and their passion for the Great Leader. I consider this a great introduction into China’s recent history. While this film was fairly historically correct and provided many facts, there were also certain obvious embellishments. I felt that the tender relationship between Wang Ruir and Mao Zedong was at times comical. While I don’t doubt that Mao Zedong was very capable of mentoring a young soldier, he has been portrayed in history as stern and serious; hence his combing of young Wang Ruir’s hair with his fingers, as well as their long conversations seemed a bit too much. Not having grown up in Communism, hearing the army songs and dances in the middle of fighting was hard to reconcile. I found that the director was very pro Red Army and Mao Zedong but the propaganda didn’t ruin the film for me. In addition, the movie showed the heartache and loss of family members during war transcends borders, cultures and politics. References Long March. (2010). In Encyclop? dia Britannica.

I deliberately cite as a bulk quotation, because I believe that it is the best reiterates one of the main ideas of the novel The History of Tom Jones, Mr. . Ydenysha Let me remind you that the 18th century in which he lived, Henry Fielding, the century of the Enlightenment, and the problem of human nature has been one of the most important for this time. Fielding, in my opinion, was able to fully reveal this other problem, give her an explanation and, oddly enough, a kind of justification inherent optimism of his work. He says that initially the person is not so bad, but the environment can corrupt it, drop to the bottom, having imparted the most disgusting habits and making it thus the epitome of evil. If a person is smart enough and able to take a critical look at their actions and their way of life, draw the necessary conclusions, it will change your life for the better, becoming the path of virtue.

In this case, all of the above would be clear. Despite all this, the novel struck me as somewhat naive. Especially the ending, when all the obstacles plagued lovers heroes throughout the narrative, by a happy coincidence instantly collapse, all the villains punished, and virtue rewarded on merit. This happy ending, after which there is a feeling that you cheated. Particular attention should be paid to the aesthetic and theoretical chapters preceding each of the 18 books of the novel. They Fielding says a lot about the problems of the artist and literature in general, about laughter as a great tool in the fight against hypocrisy and vices, which protivopostavletsya human nature as such. In theory, of course, it sounds good, but in practice usually it comes out differently. Whatever it was, in a sense of humor Fielding did not refuse.

Saving the Forest and Climate Changes

Saving the Forest and Climate Changes A global climatic change is commonly referred to as global warming. It involves the scope and pace at which a number of both physical and chemical changes take place in the world altering the nature from its original state to a hazardous condition.Advertising We will write a custom essay sample on Saving the Forest and Climate Changes specifically for you for only $16.05 $11/page Learn More This degradation in the physical environment has been suggested by numerous scientists to be caused by different factors including carbon monoxide emissions (CO2 gases), some greenhouse gases and many other. Patricia Campbell, MacKinnon and Stevens (125) argue that the greenhouse gases are released as a result of human, industrial and land usage activities, for instance, in a process of deforestation, etc. The greenhouse gases from such emissions play a key role in the depletion of the most essential ozone layer, thereby increasing the solar heating effect on the adjacent Earth’s surface as well as the rate of suns radiation on the atmosphere, hence leading to global warming. Most of the greenhouse gases are poisonous to humans and other forms of life on the earth; these are chlorofluorocarbons (CFCs), methane, aerosols, sulphur dioxide, hydrochlorofluorocarbons (HCFCs), carbon monoxide and others. In spite of being poisonous, these gases have always acted as buffers by absorbing the sun’s heat and preserving it to increase the impact of global warming on the earth’s atmosphere. The global warming effect is a catastrophe that has led to decreased levels of agricultural productivity and scorching of human skin. Global warming is on the rise nowadays due to wanton deforestation activities of humans causing widespread levels of desertification and aridity all over the globe. Regardless of the importance of forests and other vegetations in controlling the high rates of global warming and rainfall formation, it seems that humans have decided to destroy their natural ecosystems and habitats through chopping trees for timbers, charcoal and furniture. In fact, according to the United Nations Food and Agriculture Organization (FAO), the rate of global deforestation grew at an alarming rate between 2000 and 2005. The report added that the reasons for global deforestation activities ranged from land clearing for agricultural purposes, building of new houses, commercial logging and timber to creating space for commercial developments, plants, etc. The study also recorded that up to 53,000 square miles occupied by the tropical rain forest were shattered yearly beginning with the 1980s (Honey 14). Discussed below are some of the harmful effects of deforestation on the rate of global climatic changes.Advertising Looking for essay on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More The emission and formation of carbon dioxide (CO2) gas in the atmosph ere has been largely linked to the wanton destruction of trees and vegetation in regard to the fact that trees and greenery are responsible for the â€Å"consumption† or intake of the excess carbon dioxide gas released from animals as metabolic wastes; hence, when the forests are cut down (due to deforestation activities), CO2 gas accumulates in the atmosphere to trap and store solar heat and radiations. Some trees, especially in tropical rain forests, assist in reducing the rates of water evaporative cooling by forming canopies that cover and protect the underlying vegetation from direct excess solar heat, hence always keeping the greenery and soils wet, thereby increasing the levels of atmospheric moisture. Forests and other vast vegetations also act as water catchments by raising a region’s humidity levels and causing rainfalls, for instance, tropical rains. Due to the interconnectivities in tropical ecosystems, the effect of deforestation always spreads and extends to very large areas from the exact point of deforestation. The destruction of trees results into devastation of natural habitats for the millions of other plants and animals, especially small insects and birds that also play major roles in soil formation and trees pollination respectively. In fact, to some greater extent, deforestation leads to outbreaks of communicable diseases, e.g. malaria, in regard that logging roads from deforestation activities always act as disease carriers. For instance, Peru experienced high cases of malaria attacks of up to 64,000 cases in 2007 due to accumulation of pools of water in the holes left by logging roads allowing the growth of increased number mosquitoes, which transmit malaria through their bites. Moreover, extreme logging leads to an increased level of contraction of the human immunodeficiency viruses (HIVs) from bushmeat in tropical zones (White 21). Summary Deforestation activities make humans very vulnerable to natural calamities, such a s aridity, desertification due to the tendency of creation of bare lands from deforestation, soil erosion and mass flows in mountainous regions. These factors play key roles in the global climatic changes and patterns; for example, aridity is a disaster that leaves soils bare exposing them to the adverse effects of the solar heating and radiation. Another calamity of massive mudslides befell Philippines and Indonesia hitting their major towns and causing a lot of havoc due to deforestation (Driml Common 4).Advertising We will write a custom essay sample on Saving the Forest and Climate Changes specifically for you for only $16.05 $11/page Learn More In fact, according to the United Nations Statistics, the economic benefits of the deforestation are emphasized in the following ways. It is said that the forests act as sources of food, medicine and fuel to about 1.6 billion people in the entire globe. The scientists also found that up to about 2/3 of animal sp ecies lived in the woods, hence they acted as habitats for many animals and plants. The analysis also reported that deforestation caused up to about 20 percent of the yearly greenhouse gases emissions in the 1990s. Campbell, Patricia, MacKinnon, Aran and Christy Stevens.

Thomas Edison- Invention of the Kinetoscope- The role it played in Essay

Thomas Edison- Invention of the Kinetoscope- The role it played in development of Cinema - Essay Example Amongst the technologies that Edison invention was the Kinetoscope, which completely changed picture coverage in movies resulting into motion pictures. This paper explores Edison’s invention of the Kinetoscope and the role it played in development of Cinema before 1980. Prior to the invention of the Kinetoscope, the filming industry was devoid of motion pictures. Movie fanatics in the modern world greatly enjoy clear and perfect images of popular movie stars and blockbusters, which make movies more appealing to the eye than ever before, thanks to the invention by an iconic inventor, Thomas Edison. The history of screen exhibition can be traced back to the invention of Kinetograph camera by Edison in his research laboratories between 1887 and 1891.1 The Kinetograph was a famous device for capturing of images up to the year 1896. The Kinetograph was unable to project films and the viewing of motion pictures. The Kinetoscope, a peeping-gadget, enabled the viewing of motion pictures in the Kinetograph, but the viewing was limited to one person for a specified duration.2 The compact design of the kinetoscope restricted the duration of the early films to 50 feet, which was a commercial limitation. 3 In 1883, Edison recruited an assistant, William K.L Dickson and later shifted to West Orange from Menlo Park in 1887 where Edison built a huge research and experiment laboratory from where he worked under the motivation of Marey and Muybridge. At West Orange laboratory, Dickson conducted most of the research work, which utilized the phonograph techniques developed earlier.4 Edison travelled to Europe on august 2, 1889 to see the outcomes Jules Marey’s roll-film Chronophotographe experiment. In 1890, Sacco Albanese, an employee at one of Edison’s laboratories became the first person to use cylinder technology in filming. However, the method exhibited huge limitations in its displays and the quality of the images were poor leading to the rejection of the

This form of skill empowerment is not only important to the organization but is also crucial in improving personal relationships. This is the ability of the human resource manager to maintain focus on the activities that possess the greatest potential of meeting the work commitments. It is an attribute that allows them manager to understands and concentrate on facts that have a greater impact in the meeting of work requirements While other professionals may work from their homes or in pleasant working conditions, an average human resource manager works for a standard 40 hours per week. This is due to the requirements involved in fulfilling the role. These include organizing trainings and concentrating on improving employee output. Human resource managers are required to attend various refresher courses in handling the dynamics of manpower management. The mangers are also expected to work on their individual relation building attributes so as to ensure that they understand the needs of the organization and how to align them with the available manpower (Martin, 2008). Career advancement in the field of human resource goes to the doctorate level. This is the highest point of academic advancement that a human resource manager can archive.

There is no limit to the nature of compensation that a human resource manager is entitled to. The dynamic involved include the size of the organization, the

Global Issues and Institutions Essay Example for Free

Global Issues and Institutions Essay Christian Nazis killed millions of Jews in the twentieth century. Maybe it just happens so that the terrorists are all considered Islamists nowadays, as U. S. foreign policy is focused on fighting Islamic extremism. The United States has also been playing an important role in the Middle East conflict. So far it has not been able to decide upon the side it takes, even though it appears to many that the U. S. sides with the Jews rather than the Arabs in the Holy Land. Then again, regardless of U. S. foreign policy, the fact remains that most major international conflicts in the twentieth and twenty first century have revolved around differences in religion. It is a paradox, though, that religion is essentially practiced for peace. Universal Education Many attempts have been made to understand the sociological basis of terrorism. According to a new study on the causes of terrorism, ordinary people can be easily â€Å"influenced into violence (â€Å"New Research Into Causes Of Terrorism Reveals People Turn To Suicide Bombing To Preserve Identity,† 2007). † Interactions with comrades who provide â€Å"an emotional haven† in addition to a â€Å"clear focus for turbulent energies† may very well serve as a cause of suicide bombing (â€Å"New Research Into Causes†). In order to root out this cause of suicide bombing, the new study suggests that it is essential for a group that believes in suicide bombing to have interactions with people who do not consider violence as a way to achieve immortality or the kingdom of God (â€Å"New Research Into Causes†). The best method of interaction is, no doubt, education of the diversity of cultures and experience of the people of the world. The United Nations and other organizations that are not related to specific nations must be imparting an education of universal values to the people who may otherwise turn into suicide bombers. After all, illiteracy may turn into a serious illness. In fact, all problems around the world seem to have been caused by it. Although the United Nations repeatedly speaks of universal education, it remains an unaccomplished goal. International Law The Internet and globalization make it necessary to strengthen international laws and empower the International Court of Justice. Rights of foreigners are not always respected. Let us consider the example of environmental problems to understand this issue of global importance. The Ramsar Convention is one of the treaties to help improve the environment. But, such conventions are not meant to be regulatory bodies that could compel contracting parties to follow their guidelines under the rule of law. If the contracting parties fail to fulfill their contract obligations, there are no punitive measures taken by the Ramsar Convention, although the terms of the Convention are said to â€Å"constitute a solemn treaty,† and are therefore considered â€Å"binding in international law (The Ramsar Convention, 2007). † What is truly needed is to make such conventions binding in international law. At present, no contracting party can be compelled to follow the guidelines of any such convention. By empowering the International Court of Justice to undertake the task, it may indeed become possible to develop a new convention on climate change for both the developed and developing countries. What is more, like the ‘no child left behind’ law, the new convention should aim to include every single country on the face of the earth.
