Hydroelectric Energy :: essays research papers

Hydroelectric energy potentially is the result of a fortunate coincidence in which nature and the need to modernize, are combined together in an on- going cycle. The cycle being evaporated, precipitation and concentration. Having water, though, does not necessarily mean having hydroelectric potential. To be in usable form, that water must be in continuous supply, accessible and concentrated in rivers with a volume flows and a descent rate, sufficient to drive generating turbines. The only way that this system would become non-renewable would logically be if the lakes, rivers and streams dried up, therefore the resource of water becoming unavailable. The likeliness of this happening in our lifetime is next to nothing, especially in Ontario and Quebec. These areas have and abundance of lakes and down-falling rivers. Availability The availability of water in this area of the world is great. Being able to have water flowing on a downward slope is another story. It is useless if it is not flowing. The steeper the water flows, the more electricity it will produce. Hydroelectric plants can be turned into what are called peaking units in areas where power plants and high populations exist. That is because electricity demand in an area can vary widely over a period of time, sources that can easily be turned on or off are needed to meet demand peeks. Environmental Concerns Large dame change a self-regulating ecological system into one that must be managed. Placed on a river without thought to their upstream and downstream impacts they can bring disaster. Because lakes cannot survive some of the abuses that rivers can, traditional farming and waste disposal practices must be changed. The dams themselves can be threatened by the silting of reservoirs caused by soil erosion, which may destroy a dams ability to store water and generate energy. Dams can endanger little known plant and animal species. Many tropical plants or animals with potentially high economic value will be lost forever if dam reservoirs are built, because so many tropical species have be yet to be named. Even where threatened species have been indented, pressure to destroy their habitats can be irresistible. Where fish species migrate long distances to breed, dams can decrease their stocks. The Columbia river salmon fisheries in North America declined sharply after dams were built there, despite programs to build fish ladders and restock the river. How much is there? In different areas of the world, water can range to an abundance of it, to none at all. With the hydrologic cycle there will always be the same amount of water on Earth. It will just be distributed differently throughout the biosphere.

The Art of Sacrifice as portrayed in the Great Gatsby by F.S. Fitzgerald and American Beauty directed by Sam Mendes.

The Art of Sacrifice as portrayed in the Great Gatsby by F.S. Fitzgerald and American Beauty directed by Sam Mendes. Sacrifice, the concept of giving up something valuable as a means of gaining more desirable things or preventing evil, is a fascinating art that has long intrigued humankind. In particular, two American texts have captured the essence of it , The Great Gatsby by F.S. Fitzgerald and the 1999 movie American Beauty directed by Sam Mendes. Both texts closely explore the responsibility of an individual‚s relationship with his or her society for the sacrifices the individual makes; from the disillusionment of the American Dream to how the characters are affected or destroyed by it.In the world of Jay Gatsby and Lester Burnham, ideals and values are defined by their society. More specifically, theirs is a consumer-driven society, resulting in false values which place importance on materialism and hedonism, disregarding morality and spirituality. In The Great Gatsby, these values are embodied through the juxtaposition and repetition of West and East.Leonardo DiCaprio at the Body of Lies film premier...

The U.S. And Great Britain Special Relationship

The U.S. And Great Britain Special Relationship The rock-solid relationship between the United States and Great Britain that President Barack Obama described during his March 2012 meetings with British Prime Minister David Cameron was, in part, forged in the fires of World Wars I and II. Despite fervent wishes to remain neutral in both conflicts, the U.S. allied with Great Britain both times. World War I World War I erupted in August 1914, the result of long-standing European imperial grievances and arms races. The United States sought neutrality in the war, having just experienced its own brush with imperialism that included the Spanish-American War, 1898, (of which Great Britain approved), and the disastrous Filipino Insurrection that soured Americans on further foreign entanglements. Nevertheless, the United States expected neutral trade rights; that is, it wanted to trade with belligerents on both sides of the war, including Great Britain and Germany. Both of those countries opposed the American policy, but while Great Britain would stop and board U.S. ships suspected of carrying goods to Germany, German submarines took the more dire action of sinking American merchant ships. After 128 Americans died when a German U-Boat sank the British luxury liner Lusitania (surreptitiously hauling weapons in its hold), U.S. President Woodrow Wilson and his Secretary of State William Jennings Bryan successfully got Germany to agree to a policy of restricted submarine warfare. Incredibly, that meant a sub had to signal a targeted ship that it was about to torpedo it so that personnel could debark the vessel. In early 1917, however, Germany renounced restricted sub warfare and returned to unrestricted sub warfare. By now, American merchants were showing an unabashed bias toward Great Britain, and the British rightly feared renewed German sub attacks would cripple their trans-Atlantic supply lines. Great Britain actively courted the United States- with its manpower and industrial might- to enter the war as an ally. When British intelligence intercepted a telegram from Germanys Foreign Secretary Arthur Zimmerman to Mexico encouraging Mexico to ally with Germany and create a diversionary war on Americas southwestern border, they quickly notified Americans. The Zimmerman Telegram was genuine, although at first glance it seems like something British propagandists might fabricate to get the U.S. in the war. The telegram, combined with Germanys unrestricted sub warfare, was the tipping point for the United States. It declared war on Germany in April 1917. The U.S. enacted a Selective Service Act, and by Spring 1918 had enough soldiers in France to help England and France turn back a massive German offensive. In Fall 1918, under the command of General John J. Blackjack Pershing, American troops flanked the German lines while British and French troops held the German front in place. The Meuse-Argonne Offensive forced Germany to surrender. Treaty of Versailles Compared to France, Great Britain and the United States took moderate stances at the post-war treaty talks in Versailles, France. France, having survived two German invasions in the last 50 years, wanted severe punishments for Germany, including the signing of a war guilt clause and the payment of onerous reparations. The U.S. and Britain were not so adamant about the reparations, and the U.S. loaned money to Germany in the 1920s to help with its debt. However, the U.S. and Great Britain did not agree on everything. President Wilson forwarded his optimistic Fourteen Points as a blueprint for post-war Europe. The plan included an end to imperialism and secret treaties; national self-determination for all countries; and a global organization- the League of Nations- to mediate disputes. Great Britain could not accept Wilsons anti-imperialist aims, but it did accept the League, which Americans- fearing more international involvement- did not. Washington Naval Conference In 1921 and 1922, the U.S. and Great Britain sponsored the first of several naval conferences designed to give them dominance in total tonnage of battleships. The conference also sought to limit a Japanese naval buildup. The conference resulted in a ratio of 5:5:3:1.75:1.75. For every five tons the U.S. and British had in battleship displacement, Japan could have only three tons, and France and Italy could each have 1.75 tons. The agreement fell apart in the 1930s when militaristic Japan and fascist Italy disregarded it, even though Great Britain tried to extend the pact. World War II When England and France declared war on Germany after its invasion of Poland on September 1, 1939, the United States again tried to remain neutral. When Germany defeated France, then attacked England in the summer of 1940, the resulting Battle of Britain shook the United States out of its isolationism. The United States began a military draft and started building new military equipment. It also began arming merchant ships to carry goods through the hostile North Atlantic to England (a practice it had abandoned with the policy of Cash and Carry in 1937); traded World War I-era naval destroyers to England in exchange for naval bases, and began the Lend-Lease program. Through Lend-Lease the United States became what President Franklin D. Roosevelt called the arsenal of democracy, making and supplying materiel of war to Great Britain and others fighting Axis powers. During World War II, Roosevelt and British Prime Minister Winston Churchill held several personal conferences. They met first off the coast of Newfoundland aboard a navy destroyer in August 1941. There they issued the Atlantic Charter, an agreement in which they outlined the goals of the war. Of course, the U.S. was not officially in the war, but tacitly FDR pledged to do all he could for England short of formal war. When the U.S. officially joined the war after Japan attacked its Pacific Fleet at Pearl Harbor on December 7, 1941, Churchill went to Washington where he spent the holiday season. He talked strategy with FDR in the Arcadia Conference, and he addressed a joint session of the U.S. Congress- a rare event for a foreign diplomat. During the war, FDR and Churchill met at the Casablanca Conference in North Africa in early 1943 where they announced the Allied policy of unconditional surrender of Axis forces. In 1944 they met at Tehran, Iran, with Josef Stalin, leader of the Soviet Union. There they discussed war strategy and the opening of a second military front in France. In January 1945, with the war winding down, they met at Yalta on the Black Sea where, again with Stalin, they talked about post-war policies and the creation of the United Nations. During the war, the U.S. and Great Britain cooperated in the invasions of North Africa, Sicily, Italy, France and Germany, and several islands and naval campaigns in the Pacific. At the wars end, as per an agreement at Yalta, the United States and Britain split the occupation of Germany with France and the Soviet Union. Throughout the war, Great Britain acknowledged that the United States had surpassed it as the worlds top power by accepting a command hierarchy that put Americans in supreme command positions in all major theaters of the war.

The Dynamic Nurse-Patient Relationship Essay Example | Topics and Well Written Essays - 1500 words

The Dynamic Nurse-Patient Relationship - Essay Example This essay discusses Orlando’s nursing model, the dynamic nurse-patient relationship, and analyzes how this theory can be applied to nursing practice at the individual, family/group, and community/population levels. Introduction Ida Jean Orlando formulated her theoretical models of nursing in relation to her theory of dynamic nurse-patient relationship, and expanded them to involve the distinctive role of nursing in patient care. She examined the aspects that reinforced or hampered the incorporation of mental health doctrine in the curriculum of basic nursing. She developed the dynamic nurse-patient relationship model to provide nursing practitioners a model of efficient nursing practice. She investigated nursing patient care on medical-surgical settings, not individuals with psychiatric disorders in psychiatric facilities (Orlando, 1961). She recognized three aspects of nursing practice: the uniqueness and creation of nursing knowledge, the professional role of nurses, and th e relationship between nurse and patient. A nursing context comprises the patient’s behavior, the nurse’s response, and all that does not alleviate the patient’s suffering. Patient distress is associated with the failure of the person to satisfy or express his/her needs. Orlando’s Nursing Model The dynamic nurse-patient relationship is derived from the assumption that the relationship between the nurse and patient is mutual, which means that the behavior or decision of one influence the other. Orlando (1961) argues that the nursing role is different from the medical role and that the response of nurses is based on the urgent needs, demands, and experience of the patient. Basically speaking, the theory claims that nursing is one-of-a-kind and autonomous because it focuses on the need of an individual for help or support, actual or probable, in an urgent condition. The manner by which nurses relieve this vulnerability is reciprocal and is performed in a clo sely controlled or profession way that requires education and expertise. Orlando (1961) argues that one’s behavior or response must be derived from reason, not set of rules. Her theory is regarded to be an interactive model for it suggests a particular practice of planned, purposeful one-to-one nurse-patient relationship to reinforce the best nursing care intended to take care of a patient’s needs. The nursing process is activated by the behavior of the patient. The behavior of a patient, regardless how trivial, should be seen as a call for help. Patient behavior could be expressed verbally and nonverbally. When a patient needs something that cannot be met without the aid of another person, vulnerability or helplessness arises. If the behavior of a patient does not clearly express a precise description of the need, then setbacks in the relationship between the nurse and patient may occur and make it hard for the nurse to sufficiently deal with the need of the patient. A better understanding, appreciation, or resolution of incapable patient behavior becomes a main concern for the nurse for the condition will probably deteriorate sooner or later and make sufficient care, or the delivery of required assistance or support, more and more problematic. The response, decision, and behavior of the nurse are aimed at alleviating unproductive patient behavior and satisfy urgent needs as well. Patient behavior triggers a nurse response, which is the beginning of the nursing process. Proper or correct nurse response is composed

Evidence-Based Practice Project Assignment Example | Topics and Well Written Essays - 750 words - 4

Evidence-Based Practice Project - Assignment Example To help among the interventions on heart diseases, echocardiography was introduced. The use of echocardiography as a means of identifying the structural aspects and those related to functional means in relation heart diseases remain disagreed on. Some of the problems associated with the use of the machine include the recurrence rate of the problem due to failures or weaknesses related to this machine. To add on to the above is the fact that echocardiography has only been used among adults and has not been used among teenagers yet teenagers face an increased risk of heart diseases. This is a problem because teenagers must also receive the help if the machine can help them (Mane, et.al. 2012). Addressing heart diseases from a young age should be the ideal intervention. Therefore, by leaving teenagers out in the tests on whether the machine can help control heart diseases alongside other interventions is not right (Welsh, Sharma, Cunningham & Vos, 2011). As such, this problem must be re solved to ensure that teenagers have the chance to use the machine. There are several stakeholders/ change agents that are concerned or may benefit from this proposal. The first change agents will be the teenagers. This proposal directly affects teenagers and the proposed solution will be tested on them. Therefore, teenagers form the first and most important change agents and stakeholders in this respect. The second stakeholders is the parents and or guardians of the teenagers because teenagers cannot make decisions to participate in the proposed solution by themselves. Therefore, parents and or guardians come in as representatives for teenagers. The university is a stakeholder in this proposal because the proposed solution will be implemented under the university. Therefore, it is an important stakeholder in this proposal. The healthcare system, healthcare practitioners especially cardiologists, manufacturers of echocardiography and potential users are all stakeholders/
