The act was created to ensure that the working environment for the pilots was friendly. For instance, the act was aimed at ensuring that the pilots were less fatigued and formation of a pilots association. The associations are purposely to fight for the rights of the pilots. This was after a Colgan Air Flight plane number 3407 crashed in February 2009 (Fitzgerald, 2010). The crash claimed 50 lives of people. Some of the factors that were said to contribute to the crash include fatigue, training and

Igor Sikorsky’s Flying Empire I am Russian-Ukrainian, from an Eastern Ukrainian city of Ivano-Frankovks. My grandparents from my father’s side are from Russia, and my mother’s side of the family is Ukrainian, thus making me a combination of both. Being Russian in the Eastern part of Ukraine is pretty uncommon, as the eastern part closer to Poland speaks Ukrainian, and the Western part of the country mostly speaks Russian. Ukraine was occupied by Poland and Lithuania in the 14th century. Ukrainian

The History of Aircraft design By: David Roberts Imagine yourself at Kitty Hawk, North Carolina. The year is 1903. You and your brother our about to make the first powered flight in history. The wind was right and you recorded a 59 second flight over a distance of 852 feet. You have just made history, in successfully flying the first powered aircraft. This is probably how the Wright brothers, Orville and Wilbur Wright felt that day. They successfully flew an airplane with a 75 horse

Buffer solutions and common ion effect A buffer solution resists (or buffers) a change in its pH. That is, we can add a small amount of an acid or base to a buffer solution and the pH will change very little. How to calculate pH of buffer solution containing both acid and conjugate base? Dissociation constant definition 1.1 can be rearranged into [pic] or [pic] (note that due to sign change [A-] was moved to nominator). This is so called Henderson-Hasselbalch equation (or buffer equation)

the following mixture problem. Problem: What quantity (amount) of a 60% acid solution must be mixed with a 30% acid solution to produce 300 mL of a 50% acid solution? Analysis: In this analysis (an integral part of the solution process) I will state the steps in logical order. Beneath each step, in small blue indented type, I will state the reason/logic/explanation for that step. (1) Let x be the amount of the 60% solution to be added. Begin by assigning a variable to the quantity (not the rate) of

Buffering Work and Family Conflict Cyndi Willis Author note: This assignment was made by Cyndi Willis on July 25, 2014 for Kathryn Chiplis’ Work and Family course at Rasmussen College. Buffering Work and Family Conflict There are many things that create conflict when one is trying to balance their work life and their family life. Sometimes it becomes increasingly overwhelming trying to keep a job and move up the ranks to a higher paying position while still pleasing your spouse, kids, and just

Introduction Buffer is a solution that resists a change in pH when bases or acid are added. Solutions that are acidic contain high concentrations of hydrogen ions (H+) and have pH values less than seven. Buffer usually consist of a weak acid, and its conjugate base or a weak base and its conjugate acid. The function of buffer is to resist the changes in hydrogen ion concentration as a result of internal and environmental factor. This buffer experiment is important so that we relies the important
