Seriousness of Global Warming

Global warming is considered to be one of the most significant problems. The problem touches upon the rise of temperature of the Earth’s atmosphere as well as the influence of gaseous emissions and combustion gases, which are the reasons for the ecologists and scientists’ concern. Therefore, the anthropogenic factor comes into effect.Advertising We will write a custom essay sample on Seriousness of Global Warming specifically for you for only $16.05 $11/page Learn More There are a lot of scientific articles as well as books and other sources which are devoted to the ecological problem. Generally, global warming is described as a rise of temperature. One of the authors who studied this ecological problem carefully, the author Cline (1992) states that â€Å"the most serious general problem is that the reports—especially their policy aspects—focus too much on climate change up to a fixed date, 2030, instead of giving equal empha sis to the longer-term changes that will result from human actions between now and 2030.† (p. 44) The consequences of global warming which influence the future must be taken into consideration, but if one thinks about the present, there will be no need to anticipate things. The question which the ecologists ask themselves is what is to be done next? The actions of those who give consideration to this global ecological problem are not coordinated, as their quantity is not enough to affect others. Of course, it is easier to think about negative consequences which will take place in future, but not to take measures now. There are many factors which are related to the origin of the ecological problem. However, global warming depends mostly upon the so-called greenhouse effect which is re-radiated towards the lower atmosphere. (NOAA Satellite and Information Service, 2007) The above-mentioned effect is the most important factor of the Earth’s temperature regulating. In most cases it is the anthropogenic factor which is considered to be the principal reason of global warming. A carbon dioxide which is the main element of the greenhouse effect exceeds its norms by numerous times. For instance, various combustion gases influence the increasing of carbon dioxide in the atmosphere. Earlier, people thought that the climate changes depend upon the solar influence; however, today this point of view is recognized to be outdated. On the one hand, the statement makes sense; on the other one, the impact of solar effect is recognized to be rather small in comparison with greenhouse influence, so, the earlier statement is negligible. Today, it is possible to predict the results of climate changes. Thus, computer technologies allowed to create the so-called climatic system to determine the interaction between global warming and greenhouse effect. The strange thing is that it is not the concentration of greenhouse gases which causes the climate changes, but their inte raction with various physical processes does.Advertising Looking for essay on environmental studies?

The negative consequences of global warming are noticeable on small islands. The problem touched the human health as well, so there is a strong necessity to find the solution to the problem. The global ecological problem is related to every person who lives on the Earth. Thinking about global warming and its possible consequences, is the first step of the problem solution.

Make a Cold Pack from Hot Ice

Make a Cold Pack from Hot Ice There are a few different ways you can make your own chemical cold pack. You could mix citric acid and sodium bicarbonate or you could mix barium hydroxide with an ammonium salt. If you have baking soda and vinegar, you can prepare your own hot ice or sodium acetate and then use the hot ice to make a cold pack. This method is pretty neat because crystallizing the sodium acetate generates a noticeable amount of heat. Dissolving the hot ice then absorbs the heat, so you can use the same chemical to make a hot pack and then a cold pack. Heres all you need to do: Hot Ice Cold Pack plastic bag with zipperhot icewater The hot ice needs to be sodium acetate trihydrate, which is the hydrated hot ice that you get right after you crystallize it. If you only have dry sodium acetate you need to dissolve it in the minimum amount of water and crystallize it. Now, just place your hot ice in the baggie and add a small volume of water. There you go... an instant cold pack! The reaction wont get super-cold (only about 9-10Â °C), but its enough to be noticeable, plus the chemicals are re-useable.

Aging and Media For Nursing Student Assignment Example | Topics and Well Written Essays - 1500 words

Aging and Media For Nursing Student - Assignment Example The contemporary world is surrounded by media and people within the society take up the images, impressions, sounds, and ideas that the media portrays towards aging. The media reflects key values within the society (Vickers, 2007). Representation of the older people and aging in the media serves two main purposes; (a) it may lead to the revelation of the general stereotypes that are in existence in the society, and (b) it may reinforce or teach the existing stereotypes (Darnell, Krisiola and Mason, 2010). Young adults and children have limited contact with the older adults and they may develop beliefs on the issue of aging depending on what they hear and see in the media. If there s underrepresentation of the older adults in the media or most of the media representations are negative, then it follows that negative stereotypes develop (Darnell, Krisiola and Mason, 2010). There are two theories that attempt to explain the impact of the media within the society. The theories are: (a) so cial learning theory, and (b) cultivation theory. The social learning theory asserts that the young adults are mostly influenced by what they hear and see in the media and in the process the young person apes the models he or she hears or sees (Vickers, 2007). The cultivation theory asserts that the substance of the contemporary mass media has the capability of shaping the individuals’ perceptions of the universe. In this modern society, people encounter images that constantly change the way people feel and think on a number of issues.

Cancer - Research Paper Example They are able to move about at will through the body. Cancer cells can also divide faster than normal healthy cells, then becoming able of causing tumors. Pancreatic cancer, just as the name suggests, effects the pancreas, which then effects the rest of the abdominal region, including the digestive system. Unlike other cancers, pancreatic cancer tends to spread faster, which is why is is seldom discovered during its early stages; once the cancer forms, there is only a short amount of time between the early stages and the advance stages (Evans 83). Due to its rapid spreading, signs and symptoms of the cancer do not always appear right away, making pancreatic cancer one of the cancers with the greatest death rate. There is no known cause to pancreatic cancer. The cancer forms when cells in the pancreas develop genetic mutations. Once the cells have developed mutations, they grow at a rapid, uncontrollable rate. Instead of dying off as a normal cell would, these mutated cells continue t o live in the body. As they continue to multiply and grow, the assembled cancer cells can then develop a tumor on the pancreas. To diagnose an individual with pancreatic cancer, ultrasounds are usually the first method undergone, as this can detect whether or not tumors have begun to form on the pancreas.

Definition of Good and Evil Essay Example for Free

Definition of Good and Evil Essay The nature of good and evil one of humanities never ending conflicts since the beginning of time. For instance in the novella Heart of Darkness by Joseph Conrad explores the issues surrounding imperialism, and centers Marlow the main character. The conflict between good and evil is particularly evident throughout the story. In following the novella you begin analyzing and thinking theories for instance: people are inherently evil and its expressed in varieties of forms, or people are inherently good, but become corrupted by society and other outside forces. In my perspective Im in position of people are inherently good, but become corrupted by society and other outside forces I do believe theyre people who are inherently good but influenced negatively by society and endure on evil. I stand on this position because in Heart of Darkness Marlow expresses The word ? ivory rang in the air, was whispered, was sighed. You would think they were praying to it. A taint of imbecile rapacity blew through it all, like a whiff from some corpse. By Jove! Ive never seen anything so unreal in my life. And outside, the silent wilderness surrounding this cleared speck on the earth struck me as something great and invincible, like evil or truth, waiting patiently for the passing away of this fantastic invasion. (Conrad 368) This quote Marlow clarifies that hes in this situation because of the white mans pursuit for ivory which caused death and greed; in which it proves the point of good people influenced by evil forces. Another example of this is in Part III in Heart of Darkness when Marlow and Kurtz finally meet each other through the steamships departure from the Inner Station. Here Marlow describes his developing relationship with Kurtz in terms of intimacy and betrayal. Marlow also indicates that the Africa natives are responsible for Kurtzs current condition of evilness and cruelty. Finally in the end after Kurtz dies his last words were the horror, the horror I believe Kurtz is referring to the darkness in his heart or emptiness, also being a failure of his destiny. Chinua Achebe feels differently about the novella Heart of Darkness mainly because its concept of evil. She expresses that The Heart of Darkness projects the image of Africa as the other world, the antithesis of Europe and therefore of civilization, a place where a mans vaunted intelligence and refinement are finally mocked by triumphant bestiality in other words evil. Achebe also disliked the fact how the African natives were perceived as ignorant and simply just faded into the background. Achebe concluded by stating realized that no easy optimism was possible. And there is something totally wrong in offering bribes to the West in return for its good opinion of Africa. In conclusion Africa was where colonist evil dwelled in Heart of Darkness. Evil in which takes the form of imperialism, hypocrisy, ambiguity, and moral confusion. In which case proves my theory people are inherently good, but become corrupted by society and other outside forces. You can fallow Marlow in the novella in how he is forced to align himself with either the hypocritical and malicious colonial bureaucracy or the malevolent Kurtz. This will assure the reasons why the nature of good and evil is one of humanities never ending conflicts.

Silence and the Notion of the Commons :: essays research papers

The title of this essay â€Å"Silence and the Notion of the Commons† gives the same idea of people as programmable and unprogrammable similar to the idea seen in the Matrix. Whereas programmable people, who are the commons, are the people inside the matrix they are also known as the sheep, the people that believe in everything they are told. The unprogrammable people, who are the silence, are the people outside of the matrix. Ursula Franklin uses a variety of techniques in order for the audience to fully understand her message, and to inform them of the topics discussed in her essay, as is particularly apparent in paragraph 5 of her essay â€Å"Silence and the Notion of the Commons.† Franklin addresses her audience in first person in paragraph 3, â€Å"I would like to thank everyone involved in this conference, and the organizers in particular, for inviting me to deliver this talk. I am very obviously an outsider and wish to come to this group to talk about something that is central to all work that you people are doing.† Franklin addresses her audience personally. She speaks to them about something not necessarily of her interest but of the audience’s interest. Her audience is perhaps mature but may have some people that English may not be a language the understand, therefore by emphasizing very drastically on the important words in her essay by saying them frequently. It is a psychological tact that the more times you repeat a word the better the chance there is of the audience remembering it. In paragraph 4, Franklin uses repetition to emphasize sound and its sources. She uses â€Å"s† sounds throughout the whole passage to imbed the sounds into her audiences mind. The use of alliteration can first be seen in the title â€Å"Silence and the Notion of the Commons†, the sound that standout are the â€Å"S† sounds of Silence and in Commons. This idea is used in paragraph 4 by the repetition of sound and source that is then incorporated into soundscape and landscape. She also uses the phrase â€Å"mix sounds† which is ironic to the fact that she only uses the alliteration of the â€Å"s† sound in mix and in sounds. The use of alliteration also allows the audience to pay close attention to the important words. Another technique Franklin uses to maintain the audience’s attention is her sentence structure. She uses very long sentences throughout paragraph 4 and has 2 short sentences in the middle of the paragraph.
