Gas chromatography (GC) is a chromatography technique where the separation of individual components (called analytes) from a sample relies on their differing distribution between the mobile phase and a stationary phase. The mobile phase is what carries the analyte (components being analysed) through the stationary phase and in GC, it is an inert gas, (usually helium or nitrogen). The gas must be inert so it will not react with the samples to give a false reading. The stationary phase is the…

Al-Qaeda Al-Qaeda is a big threat to the United States. When 9/11 occurred it put America in a stage of being scared and worried. Al-Qaeda is an Islamic terrorist group trying to take over and spread throughout the world. Because of the U.S Troops being sent to Saudi Arabia in 1990 trying to take control over the war lords, Osama Bin Laden and his groups ‘’Al-Qaeda” has been mad at America. United States Military are trying their best to keep all of it under control. The military has to put a…

I think Harlan Coben tells us why he was initially repelled by the invasion of privacy in paragraph 1 of The Undercover Parent. He tells us Americans in general are suspicious of anything that hints at invasion of privacy. He also associates it with Dick Cheney sitting in a dark room, rubbing his hands together, and reading your most private thoughts. Even the name spyware makes you feel like you are being watched. If this was around when I was a teenager, I would have been livid that my…

Proportionality and Newton’s Second Law of Motion Abstract How does increasing the mass of an object affect its acceleration? Is acceleration dependent of the mass of an object? How do they relate? Defining and testing Newton’s second law of motion familiarizes us with this relationship. In this experiment, we use the mass of an object as an independent variable to come to a conclusion about force and acceleration. By increasing the mass of an object at an incline, one can observe the change in…

Prior to 9/11 going through an airport and taking off your shoes to go through a metal detector, or to even go through a metal detector was uncommon; Pat downs rarely happened. Passengers were allowed to take a box of knives or blades, however, they could not be longer than four inches. After 9/11 security began to focus more on airline safety. TSA mandated new security measures such as screening and medical detectors. Lastly, the United States increased surveillance. The 9/11 attack woke up the…

science alone can reveal all natural phenomenons. Feser uses the analogy of a metal detector having far greater success in finding coins in other metallic objects than any other method. Therefore, people believe that what metal detectors reveal is real. The strength of this argument is the analogy, as it supports Feser’s claim and provides an example of his argument taking action in the real world. The analogy of the metal detector shows that if scientists create something to detect objects that…

in to the prison, because it can very easily be given to the inmates. On the second day, I was able to bring my cellphone in but I left it in the control room when I was interacting with the inmates. It was very easy to bring in. There was no metal detectors to check for cell phones. If they are not checking for cell phones, cigarettes and marijuana can be very easily smuggled in. I was never checked for contraband.…

My Trip to Washington, D.C One of my very favorite places in Americas is a city rich in history and is absolutely stunning, Washington DC is my favorite city. I've been there several times this year and every time I go back I fall in love with it, so I plan on living there when I'm done with my education and starting a career there. My least favorite part of going to DC is the traveling. My favorite part of dc is the vibe while you're there and seeing all the sights. While traveling, this is…

There is not much more they can do. Schools could be more secure if they were to combine more security methods together. Schools use many different types of security. Some public schools place metal detectors at the building entrances to prevent anyone from bringing weapons onto school grounds. The metal detectors…

security. All nineteen hijackers were able to make it through. In On Native Soil it shows clips of the hijackers going through security. In the video, you can see how the metal detector continuously goes off when the hijackers go through it. According to security standards, the security guards should have tested the hand detector on a mental object first, then checked the hijackers, but…
