Analysis of The Diabetes Prevention Program Free Essay Example, 5250 words

The purpose of this report is to examine the many problems that are associated with diabetes as well as how this can be prevented. Specifically, there will be a basis for optimizing the health and well being of those with diabetes. The prevention will be combined with methodologies which can be implied to improve the health of those that have already been diagnosed with diabetes. By doing this, there is the ability to increase the conditions of those who are suffering from the disease while continuing to alter and slow down the process of diabetes that affects those with the problem. This develops a different approach to the problem while allowing those with the disease to begin to change their lifestyle alternatives and approaches to the disease. It is expected that this will create and change the problem of strategic suffering. This is based on the options for diabetes which leads to more discomfort and a lack of comfort and well being. The ongoing psychological distress and phy sical discomfort can be changed and reversed with the right approaches while allowing individuals to begin to develop a different lifestyle in relation to the disease (Mendenhall, Seligman, 2010).

According to a recent study (Lindsay et al, 2011), there are specific problem areas with health and well being with those who have diabetes.

#15 Synthesis of Ethyl Salicylate from Salicylic Acid

#15 Synthesis of Ethyl Salicylate from Salicylic Acid ____________________________________________________________ _______________ Purpose: Salicylic acid is converted to the liquid ethyl salicylate by addition of ethanol. Yields of salicylic acid (week 1) and ethyl salicylate will be found, as well as the overall yield of the 2-step conversion of acetyl salicylic acid to ethyl salicylate. Introduction: Esters are formed from the reaction of acids and alcohols: O O || || R-C-OH + HO-R’ → R-C-OR’ + H2O acid alcohol ester water The pleasant smelling oil of ethyl salicylate is made by reacting salicylic acid (week 1) with excess†¦show more content†¦Overall Yield for 2 steps (product of 2 yields above) : Questions: 1. Recalculate the overall yield for a three-step process including the 75% extraction. 2. The synthesis of a new drug may require as many as 30 steps, some of which produce much less than 90% yields.

The ester was converted to salicylic acid by base hydrolysis. The products were refluxed and recrystallized, to ensure maximum purity, and filtered, dried, and weighed. The melting point

The Industrial Revolution and Romanticism Free Essays

The Industrial Revolution and the Romantic Spirit The Industrial Revolution refers to a series of significant shifts in traditional practices of agriculture, manufacturing, and transportation, as well as the development of new mechanical technologies that took place between the late 18th and 19th centuries in much of the Western world. During this time, the United Kingdom, as well as the rest of Europe and the United States soon after, underwent drastic socio-economic and cultural changes during this time. These changes in part gave rise to the English Romantic spirit, especially in the United Kingdom. We will write a custom essay sample on The Industrial Revolution and Romanticism or any similar topic only for you Order Now During the late 18th century, the United Kingdom’s economic system of manual and animal based labor shifted toward a system of machine manufacturing while more readily navigable roads, canals, and railroads for trade began to develop. Steam power underpinned the dramatic increase in production capacity, as did the rather sudden development of metal tools and complex machines for manufacturing purposes. The Industrial Revolution had a profound effect upon society in the United Kingdom. It gave rise to the working and middle classes and allowed them to overcome the long-standing economic oppression that they had endured for centuries beneath the gentry and nobility. However, while employment opportunities increased for common working people throughout the country and members of the middle class were able to become business owners more easily, the conditions workers often labored under were brutal. Further, many of them were barely able to live off of the wages they earned. During this time, the industrial factory was created (which, in turn, gave rise to the modern city). Conditions within these factories were often dirty and, by today’s standards, unethical: children were frequently used and abused for labor purposes and long hours were required for work. A group of people in the United Kingdom now as the Ululated felt that industrialization was ultimately inhumane and took to protesting and sometimes sabotaging industrial machines and factories. While industrialization led to incredible technological developments throughout the Western world, many historians now argue that industrialization also caused severe reductions in living standards for workers both within the United Kingdom and throughout the rest of the industrialized Western world. However, the new middle and working classes that industrialism had established led to arbitration throughout industrial cultures, drastic population increases, and the introduction of relatively new economic system known as capitalism. The Romantic Movement developed in the United Kingdom in the wake of, and in some measure as a response to, the Industrial Revolution. Many English intellectuals and artists in the early 19th century considered industrialism inhumane and unnatural and revolted?sometimes quite violently?against what they felt to be the increasingly inhumane and unnatural mechanization of modern life. Poets such as Lord Byron (particular in his addresses to the House of Lords) and William Blake (most notably in his poem â€Å"The Chimney Sweeper†) spoke out?and wrote extensively bout?the psychological and social affects of the Sailor URL: http://www.
