Methods used by Transportation Safety Administration Term Paper

Methods used by Transportation Safety Administration - Term Paper Example The body ensures that the nation’s transport systems are secure through use of sophisticated technologies like bottled liquid scanner, Biometrics, Credential Authentication Technology, explosive trace detection explosive detection system and threat image projection. Secure Flight Plan is another security measure by TSA where airline passengers’ information is compared to that in the governments watch list. In order to prove the effectiveness and ineffectiveness of these programs, TSA carried out a basic training program, which revealed that a good number of these technologies are efficient, though a few are ineffectual. Explosive Detection System is one of the programs introduced by TSA to ensure security in air travel. EDS is used to screen bags in order to detect any explosive. Using the Explosive Detective machine the system can capture the image of a bag that contains an item that is a potential threat. If more screening is needed for such a bag, it is directed to the resolution room where the bag is thoroughly inspected by the security officers before it is redirected to the system (TSA, 2014). If cleared, the bag is directed to the aircraft. However, if the officers are not able to detect the alarm they can call upon the bomb squad. When this screening is used together with baggage system that is automated, there is improved security and increased efficiency. Explosive Detective System is effective for identifying threat items, which should be subjected to further screening without the screener interpreting the message. Although, the screeners who are able to interpret EDS should be cautious not to trigger the explosion when the luggage is taken for further screening Explosive Trace Detection is the second program in TSA’s list of technologies for combating insecurity. This technology is used to screen passengers and their baggage to detect if there are any traces of explosives. In this

Aspirin Assignment Example | Topics and Well Written Essays - 500 words

Aspirin - Assignment Example Two Italians, Brugnatelli and Fontana, had in fact already obtained salicin in 1826, but in a highly impure form. By 1829, [French chemist] Henri Leroux had improved the extraction procedure to obtain about 30g from 1.5kg of bark. In 1838, Raffaele Piria [an Italian chemist] then working at the Sorbonne in Paris, split salicin into a sugar and an aromatic component (salicylaldehyde) and converted the latter, by hydrolysis and oxidation, to an acid of crystallized colorless needles, which he named salicylic acid (Bellis, 2012) Acetyl salicylic acid is the chemical name of Aspirin. In other words, Salicylic acid is the major content of Aspirin. Aspirin plays a vital role in the metabolism of humans and animals. This paper analyses the various aspects of aspirin such as chemical formula, systemic names, physical and chemical properties, relevance of its physical and chemical properties and precautions while taking aspirin etc. As mentioned earlier, Acetyl salicylic acid is the chemical name of Aspirin. C9H8O4 is the chemical formula of aspirin. The elaborated chemical formula of aspirin can be represented as CH3COOC6H4COOH. In other words, each aspirin molecule consists of 9 carbon atoms, 8 hydrogen atoms and 4 oxygen atoms. Structural formula of aspirin can be represented as follows. Physically, Aspirin is a solid substance. It is colorless, odorless, white, crystalline, acidic substance. Its melting point is 137 °C and boiling point is 140 °C. Moreover, it is soluble in water. As evident from the chemical structure, Aspirin is an aromatic compound with a ring structure. It can be converted into several different useful compounds because of its ring or aromatic structure. â€Å"Molecular Weight of aspirin is 180.15 g/mole and its Specific Gravity: 1.35 (Water = 1)† (Material Safety Data Sheet Acetylsalicylic acid MSDS, n.d., p.3).
