The Dialectics of Wilson's The Piano Lesson by Elam Harry - Essay Example The ghosts are symbolic of the past that keeps haunting the African Americans. Harry’s analysis is agreeable but excessively prejudiced.The next article â€Å"Call-and-Response: Parallel "Slave Narrative" in August Wilson's The Piano Lesson† by Boan Devon, which posits that Wilsons play is a propos on conflicts that arise when deciding the degree to which the past should affect the present. He argues that author of the play uses the piano as the benchmark to develop the argument on how people view the past. The author argues that the play consist of a traditional folklore incorporated into a true but metaphorical approach on slavery. According to Devon, the metaphorical narrative revolves around Willie Boy integrated into a family folklore revolving around Doaker. The approach is captivating and agreeable as it irrefutably explicates Wilson’s play. This paper is a critique of Elam Harry’s article â€Å"The Dialectics of Wilson's The Piano Lesson† an d Boan Devon article â€Å"Call-and-Response: Parallel "Slave Narrative" in August Wilson's The Piano Lesson.† The paper focuses on demonstrating the prejudice manner in which Elam has analysed the play â€Å"The Piano Lesson† and articulate the judiciousness of Devon’s scrutiny on the same play. ... mbol of conventional African Americans who believe their history should not be deserted while Boy Willy signifies noninterventionist African Americans who feel their past was futile and agonizing and should thus not preoccupy their future.

Chemistry of common preservatives Research Paper

Chemistry of common preservatives - Research Paper Example A great amount of interchangeability does not exist because of specific inhibitory actions towards bacteria, or molds or yeasts. Although microbes may not be avoided in non-sterile preparations, attempts are made to ensure that potentially pathogenic microbes are absent. The presence and subsequent growth of microbes may lead to many chemical changes and loss of quality of food preparations, pharmaceutical products and cosmetics. The potential for this loss of quality may occur at any of the many stages between acquisition of the raw material and eventual consumption of the finished product. The history of chemical and physical preservation is closely associated with the history and development of antimicrobial agents. Since the ancient times a scientific basis of antisepsis, disinfection and preservation has evolved over the last 150-160 years. Modern research brings to light that the use of preservatives has not been an alien concept to mankind in history. For centuries, preservatives, in the natural form, have been used in the pickling process, development of dyes and colors, prevention of microbial action on wounds, perishable goods such as vegetables, dairy etc. The Native Americans even relied on the use of adding bacteria the drying process1 .The most amazing and innovative use of preserving agents was exhibited by the Egyptians in the mummification process of the dead bodies of the rulers. The use of oils and resins to quicken or slow down the decaying process were used to best effect by the Egyptian Civilization. Nowadays, food preservation has dramatically reduced, Combination of preservatives may reduce overall concentration of a preservative and natural preservative system could replace the classical ones to minimize the adverse effects. It is the simplest acid of aromatic series. It is permitted as a preservative in food-stuffs, drugs and cosmetics as sodium or potassium salt of benzoic acid. It is
