The exact meaning of Europe is ambiguous and it is not possible to Essay

The exact meaning of Europe is ambiguous and it is not possible to accurately define it. Do you agree - Essay Example In Chinese, Europe is referred to as Ouzhu- which is a derivative of the word Europa. Furthermore, the continent has also been referred to as Frengistan (land of the Franks) by the Turkish civilization. Many other languages have referred to the region in similar context, but there has not been any single undisputed explanation of the meaning of the term Europe that is used for the continent (Malmborg, 2002). Studies related to history and politics have been the source of many co mbnnclusive reforms and facts for the development of thought and academia. However, in the discussions and origins of political terms and slogans, there have been many inconclusive debates due to an absence of a factual historical dictionary. Since there has been an absence of this etymological record in the form of a dictionary, any factual brief on many political terms and slogans has been hard to find. Moreover, any research that may be taken up would in turn be significantly time consuming and may never have a conclusive statement of their backgrounds (Boer, 1995). The lack in the research material and weak records of terms and their origins, has made the structured method of investigation in political expressions and education and development of ideas weak and the theories challengeable. Many revered literary works in the field relating to philological dictionaries, especially referred for the European languages, have not been of much help either in any conclusive remarks on these political terms and semantics (Boer, 1995). The main reason for this to happen is that most of the literary research ahs been the work of the esteemed scholars and critics has been entirely focused and centred on philology and literature. Hence, there has not been much concentration and attention on works related on political semantics and historical slogans. Furthermore, the links in these works present and developed internationally along with the different views

Infra Red Spectroscopy in Chemistry Essay Example | Topics and Well Written Essays - 750 words - 1

Infra Red Spectroscopy in Chemistry - Essay Example The absorbed radiation is converted into energy of molecular vibration by the sample molecules. The frequency of absorption of radiation depends on the masses of the atoms in the molecule, the force constants of the bonds, and the geometric structure of the molecule. Hence, the resulting spectrum is an exact replica of sample contents and its molecular structure as supported by Beer-Lambert Law (Duckworth, 1998) which states that there is a linear relationship between how much light is absorbed by a sample and the product of the concentration of the absorbing species and its path length. A close examination of infra-red spectrum fingerprints reveals that absorption peaks correspond to the frequency of vibration between the bonds of the atoms of sample material while the magnitude of peaks corresponds to the amount of material present. Since each sample has a unique molecular structure just like a fingerprint so no two unique molecular structures produce the same infra-red spectrum (l eaving few exceptions). Hence the information provided by infra-red spectra about the composition as well as the structure of a molecule of a sample material clearly paves a way for both qualitative a â€Å"positive identification† and (with an aid of modern software algorithms) quantitative i. e. â€Å"amount† (Introduction to Fourier Transform Infrared Spectrometry, 2001, p.3) analysis of material, an invaluable tool for QA/QC or contamination analysis applications. For example, Ethanol content is the single most important parameter in alcoholic beverage industries. ‘For many economic and regulatory reasons, convenient, accurate, and fast quantitative determination of ethanol in mixtures is important. With the increased importance of quality assurance in industries, Near-IR spectroscopy has become an important quantitative tool for solvent characterization’.
