Nitrogen gas is often used as an alternative to carbon dioxide
for storing beer in pressurized kegs.
The smaller bubbles it produces is preferred for some types of beer.

Nitrogen Narcosis Definition
Nitrogen narcosis is a condition that occurs in divers breathing compressed air. When divers go below depths of approximately 100 ft, increase in the partial pressure of nitrogen produces an altered mental state similar to alcohol intoxication.
Description
Nitrogen narcosis, commonly referred to as "rapture of the deep," typically becomes noticeable at 100 ft underwater and is incapacitating at 300 ft, causing stupor, blindness, unconsciousness, and even death. Nitrogen narcosis is also called "the martini effect" because divers experience an effect comparable to that from one martini on an empty stomach for every 50 ft of depth beyond the initial 100 ft.
Causes and symptoms
Nitrogen narcosis is caused by gases in the body acting in a manner described by Dalton's Law of partial pressures: the total pressure of a gas mixture is equal to the sum of the partial pressures of gases in the mixture. As the total gas pressure increases with increasing dive depth, the partial pressure of nitrogen increases and more nitrogen becomes dissolved in the blood. This high nitrogen concentration impairs the conduction of nerve impulses and mimics the effects of alcohol or narcotics.
Symptoms of nitrogen narcosis include: wooziness; giddiness; euphoria; disorientation; loss of balance; loss of manual dexterity; slowing of reaction time; fixation of ideas; and impairment of complex reasoning. These effects are exacerbated by cold, stress, and a rapid rate of compression.
Diagnosis
A diagnosis must be made on circumstantial evidence of atypical behavior, taking into consideration the depth of the dive and the rate of compression. Nitrogen narcosis may be differentiated from toxicity of oxygen, carbon monoxide, or carbon dioxide by the absence of such symptoms as headache, seizure, and bluish color of the lips and nail beds.
Treatment
The effects of nitrogen narcosis are totally reversed as the gas pressure decreases. They are typically gone by the time the diver returns to a water depth of 60 ft. Nitrogen narcosis has no hangover or lasting effects requiring further treatment. However, a doctor should be consulted whenever a diver has lost consciousness.
Prognosis
When a diver returns to a safe depth, the effects of nitrogen narcosis disappear completely. Some evidence exists that certain divers may become partially acclimated to the effects of nitrogen narcosis with frequency—the more often they dive, the less the increased nitrogen seems to affect them.
Prevention
Helium may be used as a substitute for nitrogen to dilute oxygen for deep water diving. It is colorless, odorless, tasteless, and chemically inert. However, it is more expensive than nitrogen and drains body heat from a diver. In diving with rapid compression, the helium-oxygen mixture may produce nausea, dizziness, and trembling, but these adverse reactions are less severe than nitrogen narcosis.
Nitrogen narcosis can be avoided by limiting the depth of dives. The risk of nitrogen narcosis may also be minimized by following safe diving practices, including proper equipment maintenance, low work effort, proper buoyancy, maintenance of visual cues, and focused thinking. In addition, no alcohol should be consumed within 24 hours of diving.

There LIVES a kutty fellow in every man and kuttyp paappaa in every woman.
We both are enough to prove it beyond doubts!
For English language lovers here are some interesting facts:
Syzygy: The only word to have three ys. It means the alignment of three celestial bodies in a straight line, commonly the Earth, the Sun and the Moon.
Dreamt is the only word in the English language to end in 'mt'.
Tmesis: The sole term in the English language to begin with Tm- has an unusual meaning to match. Tmesis is the insertion of one or more words between the words that make up a compound phrase. For example: "what-so-ever" inserted in the middle of "whatever."
Hydroxyzine: Only one word in all of English has an X, Y, and Z. This medication developed in the 1950s can help calm you down, prevent sneezing, and impress you with unique linguistic qualities.
Queue: This is one word which is pronounced the same even if you remove four letters from it. Before it meant a line, a queue referred to the tail of a beast in medieval pictures and designs. The unusual spelling owes its origin to French, like so many words that look a little odd in English.

Talking of spellings...my little grandson knows to read all the alphabets correctly.
So his favorite pastime it to read everything he can get hold of.
I had brought a calender with the image of Ganesh in it - to use it as a writing pad.
In India they put God's pictures in all sorts of calenders . This one was from a shore mart.
The little chap read those letters as
S H O E => GAJA , M A R T => MUKA
I was amazed how he could relate the picture with the letters given below!!!

#17. Elementary facts about elements.
Titan, the largest moon of Saturn, has an atmosphere nearly entirely made of nitrogen (over 98%).
It is the only moon in our solar system known to have a dense atmosphere.
Nitrogen is in a liquid state when at a very low temperature.
Liquid nitrogen boils at 77 kelvin (−196 °C, −321 °F).
It is easily transported and has many useful applications including storing items at cold temperatures,
in the field of cryogenics (how materials behave at very low temperatures),
as a computer coolant (a fluid used to prevent overheating) and removing warts.

Decompression sickness (also known as the bends) involves nitrogen bubbles forming in the bloodstream
and other important areas of the body when people depressurize too quickly from scuba diving. Similar
situations can occur for astronauts and those working in unpressurized aircraft.

Nitrous oxide (also known as laughing gas or by its chemical formula N[SUB]2[/SUB]O)
is used in hospitals and dental clinics as an anesthetic
(removing or reducing pain and general awareness for various surgeries)
Nitrous oxide is also used in motor racing to increase the power of engine and speed of the vehicle.
When used for this purpose it is often referred to as nitrous or NOS.

#20. Elementary facts about elements.
Nitrous oxide is a considerable greenhouse gas and air pollutant. By weight is has nearly 300 times more
impact than carbon dioxide. Nitroglycerin is a liquid used to create explosives such as dynamite. It is often
used in the demolition and construction industries as well as by the military. Nitric acid (HNO[SUB]3[/SUB]) is a strong
acid often used in the production of fertilizers. Ammonia (NH[SUB]3[/SUB]) is another nitrogen compound commonly
used in fertilizers.

#21. Elementary facts about elements.
Oxygen is an element with the chemical symbol O and atomic number 8.
Oxygen is a very reactive element that easily forms compounds such as oxides.
Under standard temperature and pressure conditions two oxygen atoms join to form di-oxygen (O[SUB]2[/SUB]) a
colorless, tasteless and odorless gas.
Oxygen is essential to human life, it is found in the air we breathe and the water we drink (H[SUB]2[/SUB]0).

These days disposable medical products only are used in all places as it has
many advantages. No doubt its use is recognized by different consumers,
viz. hospital staff, private physicians, patients, and even non-medical professionals
who use it for tattoo work. Even gloves have been used in clinics, hospitals, and
doctors' places for quite some years now. As a result, disposable medical supply
market has a significant growth. I recently noticed even thermometers are available
as disposable medical product. Disposable medical supplies bring many benefits such
as health care convenience and safety .

#22. Elementary facts about elements.
Oxygen makes up around 21% of the air we breathe.
It is also the most common element in the Earth’s crust (around 47%)
and the third most common element in the Universe
(but far less than hydrogen and helium, the top two most common).
The large amount of oxygen on Earth is supported by the oxygen cycle
which involves the movement of oxygen between the air, living things and the Earth’s crust.
Photosynthesis (a process that converts carbon dioxide into organic compounds using sunlight)
plays a major role in this cycle.
