Essay on RFID Tagging - 1647 Words

Radio Frequency Identification Detection (RFID) is a technology that involves a silicon chip and an antenna, which together is called a TAG. The tags emit radio signal to devices that are called readers. One of the things that is important to know about the Electronic Product Code (EPC) is that some people use RFID and EPC interchangeably, but they are different. Would RFID work to track Products? Well, Bar Codes require a line of sight, so a person(s) with a bar code reader has to get right up on the bar code and scan it. When you are thinking about a supply chain, somebody in the warehouse would have to look at every single case. With RFID, all of the cases on the pallet would be picked up by a single swipe of a reader, even the ones†¦show more content†¦The Average gas consumer may have already used this technology without knowledge.

It stores a permanent, unique identification number that can only be read but not modified. The transponder then responds by emitting the stored number. These devices are called implantable transponder or RFID tag. RFID tagging â€Å"Micro Chipping† is an implantable microchip that is injected under the skin. It contains and electromagnetic coil and a microchip enclosed in a glass capsule the size of a grain of rice. A veterinarian using a special syringe is currently implanting these devices in animals. This passive transponder does not need a power supply and it last for decades. The identification number, which can be matched to the owner’s name, address and phone number in a national pet database.

Analysis Of Homer s The Odyssey - 897 Words

Homer’s The Odyssey is an epic poem which chronicles the tale of the Greek hero Odysseus’ journey to return to his homeland of Ithaca, and the struggles he endures on his quest. Throughout the poem, Odysseus faces many hardships and trials, and having been away from home for twenty years, his family often questions whether or not he is still alive. However, Odysseus repeatedly uses his cunning and arà ªte of rhetoric in order overcome the trials and disasters he is plagued with on his journey to return home. One instance in the poem that Odysseus shows his gift of speech and the arà ªte of rhetoric is his interactions with the Cyclops, Polyphemus. After having devised his plan to stab out Polyphemus eye with the wooden staff, Odysseus then uses his gift of rhetoric to ruse the Cyclops into drinking wine from his ship until he falls intoxicated. To accomplish this, Odysseus states, â€Å"Cyclops, have some wine. . . so you can see what kind of drink Was in our shipâ⠂¬â„¢s hold. I was bringing it to you to make an offering, hoping you would pity me And help me home.† Using his cleverness, Odysseus devises the plan to have Polyphemus intoxicated and fall unconscious, who would otherwise be too strong for Odysseus and his crew to overpower. Because of this, Odysseus and his crew are able to stab out Polyphemus’ eye, rendering him blind. After gouging out the Cyclops’ eye, Odysseus also shows his arà ªte of cleverness by quickly devising the plan to take advantage of his blindness through hisShow MoreRelatedAnalysis Of Homer s Odyssey By Homer1202 Words   |  5 Pagescoping with the idea of losing his father and letting others to rule Ithaca.

Determining Molar Mass by Ideal Gas Law Free Essays

I. Abstract: By manipulating the ideal gas law (PV=nRT), we will be determining the molar mass of an unknown volatile liquid. Heating a flask filled with an unknown, easily evaporated liquid will allow for measurements that can be taken to work out the ideal gas equation. We will write a custom essay sample on Determining Molar Mass by Ideal Gas Law or any similar topic only for you Order Now This lab will require knowledge of basic equations used in chemistry. Using these equations, such as density and number of moles(n), we can substitute different values into the ideal gas law to manipulate it. II. Materials: 250-mL Erlenmeyer flask Needle or pin Unknown liquid sample Barometer 1000-mL beaker Hot plate Utility clamp Aluminum freezer foil Hot mitt Wire gauze with ceramic center 1000-mL graduated cylinder III. Procedure: 1. Aprons and goggles on. Clean a 1000-mL beaker for use as a heating bath. Set the beaker on a hot plate and begin heating. 2. Clean and completely dry the Erlenmeyer flask. 3. Cut a square of aluminum foil to serve as the cover of the flask. Trim the edges so that it neatly covers the edge of the flask. 4. Weigh the empty flask with cover and record to as many sigfigs as possible. 5. Obtain your unknown liquid and record the ID #. Add 3-4 mL of the liquid to the flask. Re-cover the flask, making sure the edges are tightly crimped. 6. Punch a tiny hole in the foil cover with a needle or pin. 7. Heat the water in the beaker to boiling. Adjust the heat so that the water will remain boiling but will not splash. 8. Immerse the flask containing the unknown liquid in the boiling water so that most of the flask is covered. Clamp the neck of the flask. 9. Watch the liquid carefully. The liquid will begin to evaporate, and its volume will decrease. 10. When it appears that the flask is completely filled with vapor, continue heating for 1-2 minutes. Remove the flask from the bath using the clamp. 11. Set the flask on the wire gauze on the lab table, remove the clamp, and allow the flask to cool to room temperature. Measure and record the exact temperature of the boiling water in the beaker, as well as the barometric pressure in the lab. 12. When the flask has cooled completely, carefully dry the outside of the flask to remove any water. Weigh the flask, foil cover, and vapor with as many sigfigs as possible. 3. Perform a second trial, if the final mass of the flask and vapor is not within 0. 05g of the first trial, perform a 3rd. 14. When two acceptable trials have been performed, remove the foil cover and clean the flask. 15. Fill the flask to the very rim with water and pour it into a 1000-mL graduated cylinder to determine the exact volume of the flask. Record. IV.

Conclusion (36. 875 – 46. 07) / 46. 07 (x 100) = 19. 9% = percent error The first trial was very unsuccessful while the second trial was much closer to the theoretical value. The possibilities of error within the first trial include not letting the flask cool completely to room temperature before weighing and also forgetting to utilize acetone to dry the flask before the addition of the liquid. The latter was the major difference in performance of the two trials. This experiment showed that the interference of water vapor can completely wreck the chance for an accurate measurement of volume of a different gas. It is imperative to make sure that the flask is as dry as possible or the results will show a very wrong answer. It is hard to realize the prominence of water vapor in the air until an experiment like this one shows that it takes up a relatively huge space in a given volume of air. A suggestion to improve this lab could be to place more emphasis on drying the flask with a paper towel and acetone before use. How to cite Determining Molar Mass by Ideal Gas Law, Papers
