The expansion of dough Essay Example for Free

The expansion of dough Essay There are many factors that may have an effect on the expansion of dough but I will research temperature and material, the experiment is as follows. 25g of flour will be weighed into a beaker, and sugar will then be added. 30cm3 of yeast suspension will be measured in the 50cm3 measuring cylinder, and then added to the flour and sugar. It will then be stirred until a smooth paste. The paste will then be poured into the 250cm3 measuring cylinder without touching the sides. This is a precaution, because otherwise there will not be the correct amount of paste. The volume of the paste in the measuring cylinder will be recorded and the cylinder will be placed in one of the waterbaths, the temperature noted. The clock will be started and the volume recorded every 2mins for about 30mins. I think this experiment will work because dough is known to rise when heated I think that the higher the temperature, the bigger the expansion and if left over a period of time, at the same temperature, it will increase further, until a certain point. I believe this, because yeast is made up of a single-celled organism, Saccharomyces cerevisiae, which multiplies rapidly when fed sugar and the yeast will convert starch to glucose, a simple sugar. This ferments the sugar, which converts to alcohol and carbon dioxide. The carbon dioxide gas helps raise the dough and the dough rapidly expands, increasing in volume. To support my hypothesis further I had to research, I found the following sites and books helpful: http://encarta. msn. co. uk/find/Concise. asp? z=1pg=2ti=761556236 http://homecooking. about. com/library/weekly/aa072197b. htm Biology for AQA separate award by Ann Fullick. I have performed the experiment using the method mentioned previously. I have paid attention to the precautions carefully, and tried to do it correctly and as precise as possible and have obtained the following results: Time (mins) Volume (cm3) Temp: 22i C-glass Temp: 32i C-plastic Temp: 32iThe results shown in the table prove that the higher the temperature, the further the dough will rise, supporting my hypothesis. To support my hypothesis further I had to research, I found the following sites and books helpful: http://encarta. msn. co. uk/find/Concise. asp? z=1pg=2ti=761556236 http://homecooking. about. com/library/weekly/aa072197b. htm Biology for AQA separate award by Ann Fullick The graph, on the next page, shows that when dough is heated at a higher temperature it will rise faster. However, if heated in a glass-measuring cylinder, it would have perhaps risen further than it did. This can be seen by comparing the dough at 32i C in the plastic measuring cylinder (A) and the dough at 22i C in the glass-measuring cylinder (B). Although A is 10iC above B for the first fourteen minutes, they are constantly crossing temperatures. As line of best fit, starts lower than B, its intercept being 23 and Bs being 32. From the graph, the differences between the lines can be seen easily, at 37i C, it had risen the most and at 22i C, it had risen the least, the difference between the two being 46 cm3. At 22i C, it raised 28cm3, at 32i C it raised 44cm3, and at 37i C it raised 74cm3, and the graph showed this. From the line of best fit, the lines can be compared by their intercepts and gradients easily. However, the line which each set of results form is more important.Each of them show a steady rise, but the steadiest is the dough at 37i C, this suggest that perhaps this is an ideal temperature for rising dough, not too high as to kill the yeast and not too low, so it wont grow as fast and as steady. This also helps me to understand why a change in material will help the dough rise faster or slower. If in a glass container, the heat can pass through easily, and so it will rise faster, but because plastic is an insulator, the heat cannot pass through as easily. In conclusion, I can form the opinion that dough will expand more rapidly when at a higher temperature, perhaps ranging between 30iand 40i , and in a container that is not heat resistant, and the graph shows this in a simpler form. I think this because yeast multiplies at a faster rate in a high heat, however, if too high, it will die. Also, the graph shows the dough rising at a steady rate at 37i C, and so at 40i C it would perhaps rise faster, and it raises relatively well at 32i C. Although the yeast would probably rise faster in a higher heat, within bread the carbon dioxide gas given off would probably create pockets within the bread, or the yeast would begin to die. The results have turned out as expected, supporting my prediction. My method gave evidence that was reliable, and so would be counted on as correct. I believe this because it showed how yeast can be useful and expands dough in higher temperatures. By producing dough and exposing it to the conditions in which I wanted to test it, I could produce reliable results. This was done by measuring the dough carefully and fairly, using the same ingredients as a precaution, making the investigation fair; and then heating it at a steady temperature. By recording it throughout, I was able to produce a graph, to show my results in a clear and precise way. I think that I have given enough evidence to draw a conclusion. However, I think that this investigation could be advanced, by heating dough at a lower temperature, such as 15i C, in two different materials, and then the same again at a higher temperature, such as 50i C, also at a middle temperature, such as 18i C. By comparing two extremes and an intermediate, we can see if yeast will rise any more rapidly and steadily at the different temperatures and more importantly, if the materials in which they are heated make a difference. This would help support my earlier conclusion, that dough will expand more rapidly when at a higher temperature, perhaps ranging between 30i and 40i , and in a container that is not heat resistant.

The Conservative Movement Essay -- U.S. Politics

The conservative movement has played a crucial role in American politics in the post war era. Ronald Story and Bruce Laurie indentify various elements of the American conservatism. These elements include challenging authoritarian governments and modernist culture, upholding tradition, Christian religion and the rule of law, defending western civilization, and supporting republicanism. American conservatism has been characterized by competing ideologies and tension throughout history. The Americans who are politically liberal and economically conservative favor free trade, minimal state intervention, low taxes, and a small government. On the other hand, conservatives hold the view that American traditional values are normally undermined by secularism. Social conservatives have always opposed same-sex marriages and abortion, and instead have been supporting the idea of integrating prayer into the school curriculum (Story and Laurie 1). In the 1950s, after the Word War II, modern conservative movement emerged in the U.S. This conservative movement blended the elements of libertarianism and traditional conservatism. However, many historians have associated the emergence of the modern conservative movement with the New Deal. One of the most important elements of the conservative movement in 1950s is that it was an anti-communist group. This was experienced in the 1950s when North Korea, which embraces communism, attacked South Korea. Truman, who was the president at that time, tried liberate South Korea by force without obtaining the approval of the congress. Instead, he obtained approval from the United Nations. This made republicans to strongly criticize the war as well as the policies that were being employed by Truman. In additio... ... Ball, Stuart and Ian Holliday.

The Contribution of NUR 300 Class

NUR 3000 is meant to be a bridge for the adult student, by which he or she may make a smooth transition into an academic setting while assuming new responsibilities as a nursing student. The course is designed to give to the student those skills which are necessary for the successful completion of the student’s education. There are specific skills needed to be successful as a nurse and this course is designed to bring those to the student. The educational goals set by the student can best be achieved if the student is fully versed on all the tools of the trade, and NUR 3000 is designed for that purpose. During the course of this class the student participates in discussions concerning the role of the student nurse vis a vis the university milieu. The student is required to demonstrate the ability to produce an academic work meeting the guidelines of the American Psychological Association style. The student is instructed in ways to identify the tools needed by professional nurses in the course of their duties. This includes guidelines for evidence-based practice and the student is taught to apply those tools to further productivity and learning. The student is taught to identify a system in which responsibilities can be prioritized. In this course there are participatory discussions relative to the most efficient methods of educating clients and colleagues. The use of a word processor is virtually mandatory in any technical work and knowledge of the ways in which it can be used is vitally important to nurses (L. Pray, personal communication, February 20, 2007).   In this course the students becomes familiar with all aspects of the program and are then expected to be skilled in their uses. The old typewriter, which the word processor replaced, served but one purpose, which was to put print onto a sheet of paper. The word processor is multi-dimensional and saves time and effort, which can be better spent on clients and other work. The word processor has become indispensable, and students of this course are now competent on it. There are different formatting styles in academic writing. Nurses are expected to become proficient in the American Psychological style. The course teaches student nurses the nuances of this particular style, coupled with the understanding of what its primary use happens to be.   It is for scientific works primarily and has a unique method for in text citations and referencing. ‘APA is a widely accepted format for writing research papers, particularly for social science manuscripts and theses,’ (APA, n.d.). Coupled with the word processor, it is one more weapon in the nurse’s arsenal, and beneficial in the spreading of information in a uniform manner. There is a distinction between scholarly journals, periodicals and popular magazines, with much of that difference in the quality of the written word. Peer reviewed material is considered the highest authority available to the student. Journalists write popular magazine articles, for the most part. They are frequently full of opinion and conjecture. Periodicals are the most prolific in terms of sales. They are ubiquitous and come in various formats, with ‘Some periodicals [using] the newspaper format,’ (Burkart, 1964, 11-22). The course has taught that peer review material is the most reliable and valuable source of information. No academic writing can contain plagiarized material. It is not only theft of intellectual property, it is a disservice to the creator of the material. The reason that APA style is so useful is that it makes it relatively easy to cite the source of any material or idea used in an academic paper. There is no excuse to overlook the citation of another person’s work. Though Mallon wrote, in Stolen Words, that the Romans often reworded Greek literature and that Virgil is Homeric (1991), that is not a license to steal. Paraphrasing and summarizing are techniques used in academic writing to set apart words and ideas that do not belong the author of the document. They are not the same as a direct quote, but still convey the gist of the idea. Paraphrases take the original author’s words and put them into the words of the student writing the new paper. Summaries have the flavor of the original but lack the detail. Both must be attributed to the creator of the original words or ideas in the text of the new document. In this course students learn to cope with the stress that naturally arises on the job.   Job related stress among nurses can be a source of illness and lead to burnout. According to the Framingham Heart Study data, failure to show or discuss anger leads to coronary problems later in life (Thomas, 2004). This course teaches the student effective methods to deal with what can become a major problem if not addressed. The time management strategies that are taught in this course have been beneficial. The concept of assessing where the time goes and how the student spends it will be an asset to be used in the field when the student becomes the nurse. One advantage to online learning is that the student can, within limits, go at his or he own pace. The student can learn anytime or anywhere, again, within reason. However, they take up time, for they utilize the printed word as opposed to oral lecture. Still, it appears that the advantages outweigh the disadvantages. This course was designed to teach student nurses the basics job skills required in the nursing profession. It covered the topics well and did a superior job of instructing the students in the subject matter with which it dealt. References .APA style. (n.d.)

Human Rights And Its Effects On The Chinese Employees

Suicide, deaths, childhood labor, terrible working conditions, abuse of basic human rights. Can you guess who is responsible for the majority of this cruelty? A company we have become obscenely obsessed with for the past few years: Apple. It is the biggest and most well know multinational technology corporation. We keep their products in our back jean pockets all the way to our office desks. Behind their â€Å"updated† and â€Å"hip† technology lies a deep, disturbing, and dangerous truth. Millions of Apple’s employees are practically slaves by being treated like machines. This company has obscure intentions by trying to produce their goods no matter what the cost is. As it is illustrated by the article â€Å"In China, Human Costs Are Built into an iPad†, Charles Duhigg and David Barboza show the detrimental impact of this corporation upon its Chinese employees. Apple is now identified for its harmful working condition in its factories. Employees work excessive overtime without a single day off during the week as these sweatshops work all day, every day. To produce the merchandise efficiently and effectively, the workers stand at all hours of the day and leave with a decreasing amount of energy every passing day. The company provides most of its workers with the benefit of satisfying dorms. 70,000 Foxconn, Apple’s major manufacturing partner, workers are obligated to live with 20 other people in a slum three-bedroom apartment.
