High performance Essay Example for Free

High performance Essay Conclusion: There are 3 different component dyes in the mix including blue dye, yellow dye and red dye. The blue dye has the highest Rf in chromatography ( Rf=1 in water and ethanol and isoprophy alcohol). The yellow dye has the lowest Rf in chromatography in ethanol and isoprophy alcohol and middle Rf in water (Rf=0.17 and isoprophy alcohol and lowest Rf in water (Rf=0.816 in ethanol, Rf= 0.678 in water and Rf=0.680 in isoprophy alcohol). Real World Connection HPLC-MS stands for High performance liquid chromatography mass spectrometry. HPLC-MS shares the same principle with paper chromatography. They both separate mixture using the difference in different affinities to mobile/stationary phase of different components. However, HPLC-MC is far different from paper chromatography. Firstly, HPLC-MC is composed of a liquid chromatography and a mass spectrometer. This instrumentation enables HPLC-MC to analyze a much wider range of components. While paper chromatography only qualitatively separate different component in a liquid mixture, HPLC-MS can quantitatively examine each component, including Compounds that are thermally labile, exhibit high polarity or have a high molecular mass. Secondly, paper chromatography use solvent as mobile phase and paper as stationary phase, but in HPLC-MS the mobile phase is the mixture of liquid and the stationary phase is the solid through which liquid flow. Thirdly, paper chromatography can be carried out at normal temperature and pressure, but HPLC-MS sometimes needs to be done under high pressure and certain temperature to successfully drive the liquid through the solid and best demonstrate the difference in affinities of different liquid compound.

A Comparison of the Scop in Beowulf and Widsith Essays -- comparison c

The Scop in Beowulf and Widsith.      Ã‚  Ã‚   The scop in Anglo-Saxon times had a very defined role. A comparison between the scop in Beowulf and the scop in Widsith will more clearly define for us what that role was.    The 142 verses of Widsith are the oldest in the English language, and form the earliest output in verse of any Germanic people. Widsith contains a huge catalog of 70 tribes and   69 important people, many of whom are proven to have lived in the third, fourth and fifth centuries. The vast knowledge of history which was required of a good scop, just amazes the reader. The Cambridge History of English and American Literature(v1,ch3,s6,n30) states that so many princes and peoples are mentioned in the course of the poem that its importance for the history of the migration period can hardly be overestimated.   This Old English poem was transcribed by a monk around the year 1000. Widsith tells the story of   the scop Widsith, who accompanies Ealhhild, a Lombard princess, on her journey eastward from Angel to the court of Eormanric the Goth. Ealhhild, the sister of Aelfwine, King of the Lombards, is made to marry Eormanric. In this poem the geography and the chronology are not precise or accurate.    â€Å"At an early date Germanic kings began to keep professional poets, with functions not wholly unlike those of the poet laureate or official poet of later times† (Malone 75). This pretty well expresses the life of Widsith, except that he was not located at any one court, rather he travelled from the country of Egypt, India and Israel to Britain and to northern Europe, going from court to court. His home court, if it can be called such, was with King Eadgils. But Widsith travelled to all the â€Å"heathen† and non-heathen k... ...st was the theme of sacrifice. . . .† ( Malone 77).    It’s obvious from our brief comparison between the scop in Beowulf and the scop in Widsith that the scop in Anglo-Saxon times had a very defined role: He was singer, storyteller, public relations man, recipient of gifts, traveller, linguist, historian, and servant of the audience.    BIBLIOGRAPHY Chickering, Howell D..

The Media, Disasters, and Aid Essay - 2947 Words

INTRODUCTION There is little doubt that the media has a profound impact on our awareness of humanitarian emergencies and disaster relief around the world. The reality of these disasters, and our responses to them, are heavily influenced by the framework that the media uses – through exposure on television, radio and in print – to capture our attention. The media has a number of important responsibilities during a natural disaster. I have broken down their responsibilities into four stages: early warning, immediate response, post-disaster review, and implementation. While these phases do not necessarily occur one after the other without overlap, they form a good basis from which to explain the different roles of the media throughout the†¦show more content†¦The final stage is the â€Å"implementation† phase, during which the media’s responsibility is to highlight the recommendations from the post-disaster review, and put pressure on the government to change their policies. In this essay, I will examine the roles of the media through each of these phases – focusing predominantly on Australia – and determine their successes and failures in each different approach. I will also consider the crucial relationship between the media and NGOs, and identify the ways that the media can work more closely with technology to assist NGOs and public organizations in their relief efforts and disaster management plans. EARLY WARNING PHASE During the early warning phase, the role of the media is to alert victims of impending disasters and distribute disaster response advice. Effective warning systems (EWS) and disaster reduction strategies are still not a natural component to disaster management and risk reduction globally. In the developing world, there is a shortage of equipment, skills and resources, and a number of isolated communities with little or no access to technology. In developed countries, there is a lack of consensus on the ‘right’ way to handle disaster situations. The problem with EWS is that they are transmitted through multiple channels before being broadcast to the vulnerable population. In the case of a fire warning for example, the Bureau of MeteorologyShow MoreRelatedMedia and Disaster Aid Essay2988 Words   |  12 PagesINTRODUCTION There is little doubt that the media has a profound impact on our awareness of humanitarian emergencies and disaster relief around the world.
