The following should allow anyone who is either unfamiliar with Nitrox, or confused by the terminology, to reach a point where they can follow a discussion on the subject. It may also serve as a starting point for those who wish to learn about Nitrox.
The biggest question is "What is Nitrox?" Well, the air we breathe is Nitrox. Air consists mostly of two gases: Nitrogen (79%) and Oxygen (21%), and there are some trace gases that are also in the air, they exist in such small quantities that we can ignore them. Nitrox is also referred to as "Enriched Air" or air that has been enriched with Oxygen so that it has more than 21% of Oxygen usually 22% to 40% - blends that are usually used in Recreational No Decompression Dives. But really, Nitrox refers to any Nitrogen-Oxygen gas-mix, including blends that have less oxygen than air. For the purpose of Technical Diving, you learn to use Nitrox gas mixes from below 21% to up to 100% - although the richer mixes are usually used only for decompression.
Although Enriched Air Nitrox is relatively new to recreational diving, military and research divers have been using it to extend their no decompression limits for over 50 years. In fact, the first recorded Enriched Air mix was recorded by Draeger as early as 1917. The United States Navy and British Royal Navy studied and used Enriched Air in the 1940's and the United States Oceanic and Atmospheric Administration (NOAA) have more than 20 years field experience with Enriched Air used by their research divers.
There is also the question of how do you name a Nitrox mix. To distinguish one blend of Nitrox from another, the diving community uses the abbreviation EANx (for "Enriched Air Nitrox") followed by the Oxygen content percentage. For Example EANx36 is a Nitrox blend that contains 36% of Oxygen and the balance (64%) of Nitrogen: you would read "EANx36" as "Enriched Air 36" or "Enriched Air Nitrox 36" if saying it aloud. The most two common blends used in recreational diving are EANx32 and EANx36.
Why do you want to use Nitrox? You can stay longer underwater! The primary application of Nitrox is that divers use it to extend the no-decompression limit beyond normal air no-decompression limits. Nitrogen dissolves into your body while you are breathing air under pressure. The longer and deeper you dive, the more Nitrogen you absorb.
Ammonium nitrate, on its own, is relatively harmless in regards to explosives. Ammonium Nitrate is a secondary explosive; it requires a primary explosive for detonation. It is able to burn without detonating and can withstand shock in which primary explosives are unable to do When ammonium nitrate is mixed with fuel oil and detonated the results can be catastrophic. The Oklahoma City bombing of 1995 is evidence of the impact of a blast using ammonium nitrate and fuel oil, known as ANFO. Timothy McVeigh parked a van filled with ammonium nit...
Poison gas was perhaps the most feared weapon out of all. Created to overcome the long stalemate style of trench warfare, its purpose was to draw out soldiers hiding in the trenches. One side would throw the poison gas into the enemy trenches and they would either wait for their enemy to come out into open fire or perish in the trenches. The first poison gas used in battle was chlorine at the start of the Second Battle of Ypres on April 22, 1915 by the Germans. Shortly after, followed the phosgene. The effects of these gases were ghastly. Chlorine was the most deadly as "within seconds of inhaling its vapor, it destroys the victim's respiratory organs, bringing on choking attacks" (Duffy). Phosgene had similar effects, except the fact that the effects started kicking in after 48 hours of inhalation. In September 1917, the Germans introduced the mustard gas or Yperite which was contained in artillery shells against the Russians at Riga. Those exposed t...
Pressure, the weight pushing on something, is a vital part of scuba diving. As a diver sinks deeper into the water, the pressure pushing on the person's lungs pushes harder. This can be very dangerous to a person's safety. While the water is pushing on the outside of the lungs, pressure in the inside of the lungs is pushing out. If this pressure isn't the same as the weight from the water pushing on the lungs, the diver could have breathing problems and possibly die. To equalize these two pressures, modern scuba gear is equipped with a device attached to the air hose called a demand regulator that controls the flow of air getting to the lungs, changing the pressure inside.

... 2010). When treating for hydrogen sulfide exposure, nitrite therapy may be included in order to aid recovery (Oreshan & Stevens, 2011). If exposure to hydrogen cyanide occurred, then the individual should also be given a specific cyanide antidote kit (Oreshan & Stevens, 2011).
Mustard gas was not the only example of chemical weaponry used during World War I. The first example of this was the Germans use of a gas called phosgene in mid-1915, which caused drastic damage to the lungs (Mack 2). The Germans began using mustard gas in 1916 and soon both sides began to use poison gas as a weapon. At a lab at American University, which at its peak employed over 1,200 scientists specifically to create chemical weapons for the war, a new gas called Lewisite was developed. Lewisite poisoned its victims through the skin and rendered gas masks useless against it. During the war as many as 50 different gases were used by both sides (Mack 2). When the war e...
Transition: Now that you know what the cause of narcolepsy is, let's talk about how people treat narcolepsy.
- The amount of times the mixture was stirred. We stirred the mixture until the Ammonium Nitrate was dissolved, so the amount of times we stirred after each teaspoon was different.

This fluid is made up of 32.5% urea in 67.5% de-ionized water. This mixture is then injected into the exhaust stream using an advanced catalyst system. When DEF is released into the exhaust stream the hot exhaust causes the fluid to release ammonia which then breaks down the greenhouse harming gas of NOx into nitrogen and water. This fluid must be refilled at approximately every 10,000 miles (Voelcker).
“People have been diving ever since primitive man was forced to collect food from the sea,” says HawaiiScubaDiving.com (“History of Scuba Diving”, HawaiiScubaDiving.com Internet). Man has always been curious about the underwater world and has sought to explore it. This drove man to come up with new ways to extend his reach into the underwater world and to make the trip less difficult. Over time underwater exploration has been made easier due to man’s passion for exploring a fascinating new underwater world. Inventions such as regulators, self-contained breathing apparatuses, oxygen tanks, neoprene suits, and many more technologies have been used to make underwater exploration as easy and efficient as possible. Scuba diving has evolved into a wide range of advanced technology for the average person to explore a whole new underwater world.
Nitrogen containing flame retardants release stable and inert compounds like nitrogen gases which stop the fire cycle by either interfering with the flammable gases or with the thermal degradation of the burning material. Nitrogen containing FRs can also enhance the performance of phosphorus FRs when

We have all been underwater at some point in life whether it was in a pool, lake, or in the ocean, but that was probably for a short amount of time. With Scuba Diving, you get the opportunity to be underwater for more than 10 minutes at a time without having to worry about things on the surface. With Scuba Diving already having been banned temporarily a while ago in Crater Lake because of concern about the environmental impacts of invasive species to the marine ecosystems, some people think that Scuba Diving could become banned in more places, if nothing is done to combat the problem. Today, I will discuss Scuba Diving and its effect on the environment along with how to make it safer for the environment. During this past year, I learned to scuba dive and was certified for Scuba Diving at Neptune Dive and Ski. Today, I will discuss the effect of Scuba Diving on the environment through my research, product, and learning stretch. The first task that I was faced with was gathering information about Scuba Diving and researching the problem and the multiple ways to resolve the problem that it has on the environment. I researched the problem and ways to resolve the problem that Scuba Diving has on the environment, with my thesis focusing on how Scuba Diving although damaging to marine life and plants, could with the proper training be one of the best helpers of the present and for the future of the ocean life. Scuba Divers go into some of the nicest bodies of water in the world with the intent to observe and interact with the environment that is beneath the water. However, some Scuba Divers lack the proper training and knowledge necessary to dive in the water safely and carefully. Scuba Diving is meant for recreational use and for educat...
