The Water Cycle Essay Example For Students
The Water Cycle Essay Title of Paper : CyclesGrade Received on Report : 100The movement of water from the atmosphere to the Earth and back to the atmosphere is called the water cycle. The water cycle consists of an alternation of evaporation and condensation. Water molecules enter the air by evaporation from the ocean and other bodies of water. In the air, the water molecules condense (in clouds) and then return to the Earth in the form of precipitation (rain). On land, most of the rainwater runs along the surface of the ground until it enters a river or stream that carries it to a larger body of water. Some water sinks into the ground and is called ground water. The upper surface of ground water is known as the water table.

Nitrogen is available to organisms in several ways. Free nitrogen gas makes up 78 percent of the atmosphere.Nitrogen is also found in the wastes produced by many organisms and in dead and decaying organisms. The movement of nitrogen through the biosphere is called the nitrogen cycle. However, most of this nitrogen cannot be directly used by living things. It must be converted into other forms. Certain bacteria that live on roots of plants such as legumes (beans, peas, and peanuts) change free nitrogen atmosphere into nitrogen compounds (nitrates and nitrites) that can be used by living things. this process is known as nitrogen fixation, and the bacteria are called nitrifying bacteria. Once the nitrogen compounds are available, plants use them to make plant proteins. Animals then eat the plants and use the proteins to make animal proteins. When the plants and animals die, the nitrogen compounds return to the soil. Eventually other bacteria in the soil break down these nitrogen compounds into free nitrogen in a process called denitrification. These bacteria are called denitrifying bacteria. Through the process of denitrification, free nitrogen is returned to the atmosphere. Carbon and Oxygen CyclesThe process by which carbon is moved through the environment is called the carbon cycle. During photosynthesis, green plants and algae use carbon dioxide from the atmosphere to form glucose. Consumers and decomposers use glucose in respiration, during which they produce carbon dioxide. Carbon dioxide is then released into the atmosphere, completing the carbon cycle. The movement of oxygen through the environment is called the oxygen cycle. During photosynthesis, water molecules are split, releasing oxygen into the atmosphere. The oxygen is used by most organisms for respiration. During respiration, water is released. The water is absorbed by plants, and the cycle begins again.

Gorillas in the Mist essays
Gorillas in the Mist essays For my book report, I read the book Gorillas In The Mist by Dr. Dian Fossey. Dr Diane Fossey began what was to become one of the longest field studies of the Gorilla gorilla beringei or the mountain gorillas. This book tells the story of Dians life studying the gorillas of the African rain forest. Dian combines adventure with valuable scientific knowledge to make a truly wonderful and interesting book. The main purpose of this book was to inform people about the mountain gorillas and of all of the problems the mountain gorillas face today. Diane Fosseys interest in the mountain gorillas began when she was young. Diane first began studying the gorillas of the African Rain Forest at the Parc des Virungas in Zaire, but she soon had to move her study site to the Parc des Volcans in Rwanda. It was there where she set up the Karisoke Research Center. Diane began her studies of the mountain gorillas there in 1967. The mountain gorillas are endangered and are becoming closer and closer to extinction every day. Dr Fossey wanted to find a way to help these gorillas. She created a study of how all of the gorillas lived so that she could better understand them and what might be done so that the population downfall could recover. Diane found that poaching, bad land management, and captivity were the main problems the gorillas were facing. Diane found that like humans, the mountain gorillas are truly social animals. They rely heavily on social interactions. The mountain gorillas live in very social family groups. Each member of the family has a certain role. If something bad happens to one family member, it can put a lot of stress on the other members of the family and can have devastating results. When Diane observed this, she did everything she could in order to keep the families together. Poaching was one of the main causes for death in the gori ...

Case Law Terms Essay Example | Topics and Well Written Essays - 250 words
Case Law Terms - Essay Example Precedents and stare decisis go more hand-in-hand with each other than statutory law, though a statutory law is often created based on precedents, thus also sharing similarities. The differences between precedents and stare decisis is that a stare decisis cannot happen without precedents. If there are no precedents, judges cannot use past knowledge and experience to determine a case, therefore not implementing stare decisis (Sri Ram, 2008). Statutory law can stand on its own, consisting of the laws set down by the legislative branch. However, statutory law can also consist of the laws and regulations that have been formed due to precedents; once a judge sees the usefulness of a precedent, the legislative branch can alter it to be a statutory law. In my opinion, of the three terms provided, the one that has the most significance to criminal law is precedent. Precedent allows other courts and judges to make use of rulings or principles set forth by a past case; in the event that an unlikely or unusual case is made known, precedents can be used to determine what the outcome of the case should be. Precedents help to keep things moving in a criminal case, providing courts and judges with the information they need to determine the ruling of their

The Effectiveness of Knowledge Management In Organizations Literature review
The Effectiveness of Knowledge Management In Organizations - Literature review Example This report stresses that the globalized business environment is featured with the fast changing business condition, high production, flexible organizational structure, information and communication technology, market liberalization and partnership development. With the changes in the environment, the intensity of competition is sharpened in the market. Therefore the companies are forced to develop and implement new strategies for improving the functionality and quality of the products in order to survive in the market. This paper makes a conclusion that the application of knowledge management is very critical and difficult to be implemented and also it is very time consuming. But the advantages and its contribution in the present world has replaced its limitations or disadvantages. Every organization is required to adopt the concept of knowledge management in their organization for its workers or employees. Knowledge management contributes significantly towards the growth and development of the organization. The organizations are expected to recruit skill and knowledgeable employees in their organization, since the inability or inefficiency of the workers in the company may affect the productivity or performance of the whole organization or entity. Knowledge management through the learning, strategy and information technology influenced positively the organizational performance in terms of its return on investment for achieving its long term as well as short term goals of the organization. It has a strong affect on the productivity of the organization.

Air Forces Northern incident awareness and assessment playbook Essay Example for Free
Air Forces Northern incident awareness and assessment playbook Essay Ethics Introduction            The United States Northern Command (USNORTHCOM) is the combatant command that is responsible for security and defense. They conduct Defense of the Civil authorities through providing capabilities to the DOD, Department of Defense from their land, air and sea components in support of the leading federal policies geared towards responding to any homeland security threat.            Among the capabilities that the DOD brings to their operations is the ISR and IAA. There is no difference between these two terms only that the term IAA has just been coined by the USNORTHCOM to denote the application of ISR when it is applied domestically to support the homeland security. The ISR operation mainly consist of flying both manned and unmanned platforms which are set to revolve over the battle field top provide a clear picture of the situation underneath. During the wartime, this picture could include the location of roads and deposition of the enemy and also the information that may be required so as to target the enemy. ISR provides a clear picture of situational awareness that could not only be used strategically to gain the full picture but also tactically to gather intelligence information that are useful in engaging individual targets. The situation awareness that is provided by the IAA/ ISR becomes a significant force multiplier which the commanders have been known to highly rely on.            There are many obstacles to realizing full potential for the ISR in homeland security. Currently there is statutory, doctrine, ethical and policy obstacles that exist to prevent ISR from reaching their full capacity for the homeland security provision.            Improved doctrines will see the department of Defense improve their ability to deliver IAA capabilities to the local, tribal, state and also the federal entities. The consumers all over the country and also the whole world will benefit from improved IAA capabilities.            The most significant ethical issues come secondarily where IAA capabilities are employed domestically. This is because it is known that all the American citizens enjoy freedoms of privacy, expression and they expect this to be fundamental and be respected in the best way possible. The American citizens highly value their freedoms and hence loath ideas that seem to threaten their constitutional protection.            In publicizing the use and purpose of IAA, I think there is a big ethical consideration in it because the citizens will get to know the function of IAA and how they function. They will not think that their freedoms are being infringed on but know that this is a military operation and that is how they are and should be carried hence in so doing, there will be no blame game between the government and the citizens.

Feminist Rhetoric in Uncle Toms Cabin by Harriet Beecher Stowe :: Feminism Feminist Women Criticism
Feminist Rhetoric in Uncle Tom's Cabin       In considering whether Harriet Beecher Stowe's book, Uncle Tom's Cabin, is an example of, or contains remnants of, feminist rhetoric or not, one must first solve the problem of defining what is meant by the term feminist. This is difficult to do when one considers that Uncle Tom's Cabin was written over one hundred and forty years ago, and that feminism has moved through so many different stages since that time. One must resist applying the standards of twentieth-century feminism to Stowe's time, and instead, try to view Uncle Tom's Cabin as it would have been viewed given the sentiment of the time. In order to do this, one must first define feminism within the historical context of the 1850's, when Uncle Tom's Cabin was published.      Perhaps the term feminist itself was not commonly associated with women's rights in the 1850's, but certainly the ideal was. The climate of the time in which Stowe published her anti-slavery novel was fruitful with unrest, not only because of the slavery issue, but also because of women's rights issues. The focus of the women's rights movement, led by women such as Susan B. Anthony, Lucy Stone, and Elizabeth Stanton, was not only women's attainment of the vote, but also the emergence of women as public citizens, a role that went beyond that of ruler of the domestic, private sector.      Women's suffrage was first proposed in the United States in 1848 at the first women's rights convention in Seneca Falls, just two years before Uncle Tom's Cabin was published. At this convention, a Declaration of Sentiments that paralleled the wording of the Declaration of Independence was drafted, insisting on the adoption of a women's suffrage resolution. The Women's Rights movement of this time also advocated more liberal divorce laws, less restrictive clothing for women, coeducation, and the right of married women to control their property. Though it would be seventy years before women would be granted the right to vote by the Nineteenth Amendment to the Constitution, the Women's Rights movement was in place and active during the time that Stowe wrote Uncle Tom's Cabin.      Even so, Uncle Tom's Cabin is seemingly about slavery, not women's rights, and it is not erroneous to assume that Stowe's intention was to highlight the evils of slavery and the decay of human morality, rather than directly discuss women's roles when she penned the novel.
