Harnessing the Energy of the Oceans :: Technology Engineering Papers

Jamie Lee Wise’s essay examines the varying sources of electrical energy that we can draw from the oceans. In her well-organized and researched essay, Wise carefully explains the sources and then discusses both the benefits and drawbacks of each source. In the end, Wise’s paper argues that "public awareness and education concerning the benefits of renewable energy sources need to be increased," and that the oceans can be a valuable resourece "only if we take steps to preserve this natural wonder and use it responsibly." Harnessing the Energy of the Oceans Introduction The oceans cover nearly three-quarters of our planet and contain a vast reserve of resources, yet we are only beginning to tap their full potential. The oceans can provide a wide variety of foods, desalinated water, minerals, electricity, transportation, and recreation for the people of our world; however, this discussion will be limited to sources of electrical energy that can be harnessed from the seas. The world’s energy consumption is currently doubling every 12 years and the consequences of our heavy dependence on fossil fuels are becoming increasingly apparent. Several studies have estimated that our "present reserves of oil and natural gas will be consumed within a few decades, and coal within a few centuries." In addition, "political instability in the Middle East has demonstrated the economic consequences of oil dependence" (Bregman, Knapp, and Takahashi; 1996). Environmental and political concerns are just two reasons why alternative energy sources, such as ocean energy conversion, need to be considered. Overview of Ocean Energy Conversion Technologies Technologies that currently exist for generating electrical power from the oceans can be grouped into six broad categories: thermal energy, tidal power, wave power, ocean currents, ocean winds, and chemical sources. According to Ron Bregman, an Ocean Resource Engineer, the most promising and well-developed of these technologies are thermal energy, tidal power, and wave power (1996). Thermal Energy The oceans are the world’s largest solar collectors. Each day the oceans absorb an amount of solar radiation equivalent in heat content to about 250 billion barrels of oil, according to Michael Champ in Sea Technology (1995). This solar energy that is absorbed by the oceans as heat can be converted to electricity by a process known as Ocean Thermal Energy Conversion or OTEC. This technology is based on the large temperature differential between the warm tropical surface waters and the near freezing waters of the deep ocean (Vega, 1995).

Alice in Wonderland Essay

It’s almost impossible to set this story in the time and in the space because nearly all of it forms part of a dream: Alice was very tired and suddenly she felt asleep and began to dream. However, she didn’t realize that whatever she saw in Wonderland was only a dream, a product of her imagination but not the reality. Anyway, we could say that there are two main stages: the real world and Wonderland, the fictitious one. In Wonderland all is â€Å"nonsense† and strange, you don’t know what’s going to happen in each situation. The real world only appears at the beginning and at the end of the story when she wakes up from her nap. Because of it, this world is not very important for readers and for Alice too, who prefers living in a world completely different from hers. Interesting and strange things only happen in Wonderland where everyone is mad. Moreover, there we can see a lot of different places where Alice spends her time like the rabbit-hole, the house of the rabbit, the garden, the house of the Dukes. The time is not very clear because Alice thinks that she has spent a lot of time there, but all her adventures only last the time of her little nap. When you are sleeping you can believe that you have spent a lot of time dreaming and perhaps it has been no longer than fifteen minutes. She doesn’t have any kind of time in Wonderland and everything happens all at once and very quickly; so that she didn’t realize.

BCR Importance of nitrogen Essay

1. Probably they include negatives and, if possible, positive controls. Is your negative control a test plant that is planted in a pot with no legume planted in the pot? Do you have any other negative controls? How about positive controls? Are there some plants which you know will grow well under the conditions that you are specifying? Are you using these as positive controls, while your test plants will be a different type of plant? 2. I suspect they also include a method of checking, periodically, for results â€Å"over time,† meaning either daily, weekly, monthly †¦. 3. Wouldn’t you want all of your test â€Å"subjects† exposed to the same environmental conditions, with the exception of the one element for which you are testing. That means that all get the same amount of light, water and soil and that the light, water and soil are from the same source. So, you will need a way of measuring the amount of light, water and soil. If you are planting in containers, wouldn’t you want all of the containers made of the same substance, instead of having some be of plastic and some of wood? Wouldn’t you want them to all be the same height, width and depth? Wouldn’t you want them all oriented with respect to the sun such that none blocked sunlight from the others? Wouldn’t you want to weed them all frequently and regularly to insure that the presence of weeds did not adversely effect one or the other of your test subjects? I suspect that your instructor wants you to say in your experimental proposal write up how you will orient the containers and what they will be made of and what are their dimensions and how often you will check for weeds and measure light water and soil†¦ 4. Won’t you need to decide what constitutes a positive result and what constitutes a negative result. 5. Probably your instructor wants you to choose an objective measure for your results and state what that will be. For example: If you are growing other plants along with the legumes, will you measure the growth of their stems with a ruler? If they are branched, will you only measure the total height, or will you measure all of the branches separately? If they have fruit, will you weight the fruit? If you weigh it, how will you decide that it is time to pick and weigh it? At the end of the experiment, will you remove the whole plant, roots and all and weigh it? 6. Will you plant the legumes at the same time that you plant the test plant? or will you plant the test plant on day 5, 6, 10†¦ after the legumes have been planted? Will you plant only one legume to each box? If you have them growing at the same time, how will you orient your plants so that neither the legume nor the test plant will overshadow the other but that the roots of the legume are close enough to effect the soil for the test plant? Or, if you don’t think that will work, will you plant the legumes and let them grow and die before you plant your test plant? 7. How will you record what you have done? Will you make a spreadsheet and record that, for example, you have gave all the plants a cup of water per day or a quart of water twice a week? Where will you note the growth of the plant? how many weeds you pulled? Will you note the conditions of the leaves of your test plant or the conditions of the legume plants? Where will you note any unforeseen changes? 8. How will you write up your results? Most scientific papers have 5 sections. Does your instructor wish for you to include this in your proposal? 1) Introduction, 2) Materials and Methods 3) Results, 4) Conclusions and Discussion, 5) References

Researching Social Indicators Of Childrens Well-Being In The United

Researching Social Indicators Of Childrens Well-Being In The United Researching Social Indicators Of Childrens Well Children in Indiana I have chosen Indiana, known as Americas Heartland, as a representative because its middle of the road status geographically, socially, and politically. This is reflected in its nearly medium position in the ranking of states by poverty, infant birthweight, and per pupil educational expenses (Children in Indiana 1). However, Indiana ranks in the bottom 30 percent in regards to mothers who received pre-natal care as well as infant mortality (Children in Indiana 1). In both of these categories it ranked 34 out of 50, and there is some statistical indication that these two factors are related.In May of 2008, the Indiana Family and Social Services Administration refused to adopt a policy that would have expanded pregnant womens access to prenatal care. The policy would have granted "immediate, temporary health coverage through Medicaid to pregnant women in households earning less than twice the federal poverty level, or $28,000 for a family of two" (Indiana Medicaid A gency Refuses). Indiana has one of the highest rates of infant mortality and in 2004 the rate was "eight deaths per 1,000 live births, compared with a national rate of 6.8 deaths per 1,000 live births" (Indiana Medicaid Agency Refuses). It is common sense that pre-natal care has a significant impact of the health of the child at birth. Yet, Indiana has lagged behind the US in its willingness to cover pregnant women under the Medicaide Program.Indianas lack of commitment to childrens health reflects a conservative economic philosophy, which also extends to education. In Indiana, fourth grade school children are below the national average in both reading and math, and over 70 percent of the 3 and 4 year olds in poverty are not enrolled in pre-school (Children in Indiana 2). In contrast to many other states, Indianas policies fail to reflect the latest research in child development. Though Indiana has a substantial budget surplus, the state fails to support their children with the fina ncial support required to give them a healthy and well-educated start to life (Greninger).

Leadership Essay Example | Topics and Well Written Essays - 500 words - 46

Leadership - Essay Example He must use his power to fix things in accordance with the ethical standards. Moral courage is one of the many characteristics a leader must possess because if he lacks moral courage, he will never be able to take a positive step for those working under his leadership. Moral courage serves as the backbone of leadership. In a corporate setting, moral courage serves as the strength of character which allows the leader to lead his people without any fear of anyone or anything. When a leader is practicing moral courage, he has the guts to stand for his subordinates when needed, fight against injustice and suggest fair rewards and punishments. If an organization possess a leader who does not take righteous actions and decisions when required then the organization is likely to experience failure. We agree that it is a commander who leads a regiment and any failure on the part of regiment actually represents the poor leadership skills and lack of moral courage of the commander. If a leader can differentiate between right and wrong accurately and can raise a voice against the injustice going on regarding the policies, procedures and structures within an organization, only then he can bring about positive change in the culture as well as in the mindset of people. But it is really essential for a leader practicing moral courage that he must think and act within the ethical boundaries laid down by the organization. Sometimes the actions made by leaders in the name of moral courage allow those working under them to emulate them thereby setting a trend. This trend could be positive or negative. For instance, in the case study ‘Darker Shades of Blue’, Lt. Col. Holland gave a great flying performance for his 1993 Fairchild air show where he exceeded the technical order guidance thrice. The juniors who have seen Holland flying the way he likes by ignoring the defined guidance
