TOMB OF THE UNKNOW SOLDIER November 7‚ 2011 1. The Unknown Soldier fought in World War I. The burial place of the unknown soldier was in France‚ near the battle at Vimy Ridge‚ marked by a tombstone that read “Known unto God”. The remains of an unidentified soldier were returned to Canada to the Tomb of the Unknown Soldier‚ a specially designed sarcophagus directly in front of the National War Memorial in Ottawa‚ the National Capital. 2. The remains of soldiers that fought

Staphylococcus epidermis (gram positive) bacteria for 24 hours (in an incubator)‚ garlic will have the strongest antimicrobial effect. This is because of allicin (an active principle of garlic homogenates)‚ which has a chemical reaction with thiol groups of enzymes in the bacteria. Ginger will have the least antimicrobial effect. This is because there are not as many chemical reactions with enzymes in the bacteria. Risks: The risks of using Staphylococcus epidermis bacteria to test in microbiology are few

Cogswell ENG2D- 02 October 15‚ 11 Fear of the Unknown People are quick to judge‚ fear and hate the unknown. Some people may not admit it but everyone is plagued with the tendency to let our imagination take over reality and turn it into the unknown. An excellent example of this is in William Golding’s novel Lord of the Flies. All the boys in Golding’s novel are totally indulged in the theme of fear of the unknown. All of these have some “unknown” element to them; they can’t see in the dark‚ they

we know that we know. There are known unknowns. That is to say there are things that we now know we don’t know. But there are also unknown unknowns. There are things we do not know we don’t know. So when we do the best we can and we pull all this information together‚ and we then say well that’s basically what we see as the situation‚ that is really only the known knowns and the known unknowns. And each year‚ we discover a few more of those unknown unknowns.” I would have told you that I thought

The melting point range is defined as the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid. This data can be tabulated experimentally through multiple trials for an unknown and referenced against the chemistry literature for a known compound. In Macroscale and Microscale Organic Experiments‚ 5th ed‚ Williamson notes that most pure organic solids will melt repeatedly over a narrow temperature range of 1°C. As a measure

performed this test‚ the initially slant for unknown microorganism #17 is important. For this lab‚ two identical slants are used for two reasons. Firstly‚ the slant can be used to make sure that there is no contamination from the Nutrient Agar plate. Secondly‚ the second slant will become a stock culture to prevent the shortage of slants during performing the series of tests. Kliger’s Iron Agar tests can be used to determine multiple characteristics of unknown microorganism #17. Kliger’s Iron Agar slants

Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes. Materials known as acids when dissolved

The poem the unknown citizen written by w.h Auden portrays from the point of view of the government what or how an ideal citizen should look like. This piece is written in third person omniscient to project a non-bias perspective and that way transmit the “truth” without being affected by feelings or personal point of views. Moreover at the end of the poem the author makes a relevant turn which effect is making the reader question himself if what was depicted before is the right thing‚ if that ideal
