  Medical Facts Regarding Oxygen
Oxygen is one of the five basic elements of all life (oxygen, hydrogen, carbon, nitrogen and sulphur) and is colorless, tasteless and odorless.
Hypoxia, or lack of oxygen in the tissues, is the fundamental cause for all degenerative disease.
Oxygen is brought to the lungs by respiration where it diffuses from the air into the blood stream through over 140 square meters of internal lung surface area called the gastric mucosa.

 Stellar nucleosynthesis - Wikipedia, the free encyclopedia
The processes involved began to be understood early in the 20th century, when it was first realised that the energy released from nuclear reactions accounted for the longevity of the Sun as a source of heat and light.
The prime energy producer in the sun is the fusion of hydrogen to helium, which occurs at a minimum temperature of 3 million kelvins.
The second process, the carbon-nitrogen-oxygen cycle, which was also considered by Carl Friedrich von Weizsäcker in 1938, is most important in more massive stars.

 Oxygen, Cure for Cancer?   (Site not responding. Last check: 2007-10-26)
In order to understand the dramatic effect of increased oxygenation on cancer (and all anaerobic diseases) it is important to explain the conditions (and the only conditions) which allow cancer cells to not only survive but multiply and flourish.
Thus the development of a shortage of oxygen in the blood could very well be the starting point for the loss of the immune system and the beginning of feared health problems such as cancer, leukemia, AIDS, candida, seizures, and nerve deterioration.
Oxygen is a powerful detoxifier, and when its quantity is deficient, toxins begin to devastate body functions and deplete the body of life-giving energy.

 Protecting the Environment   (Site not responding. Last check: 2007-10-26)
Oxygen is necessary for the actual burning process, i.e., for chemical reaction of the fuel.
A phenomenon such as burning behaviour is not determined solely by the physical and chemical properties of the plastic but by many other variables, such as its geometry, form, the applied ignition source and ventilation.
The burning be-haviour of a plastic is thus not an intrinsic property of the material.

 Student Pilot - Flight Training Online
Oxygen is transported throughout the body in the bloodstream which contains, among other things, the red blood cells.
Hemoglobin picks up oxygen at the lungs and carries it to the tissues for use and picks up carbon dioxide at the tissues and transports it to the lungs for exhalation.
The amount of oxygen that can be carried in the blood depends, to a large extent, upon the pressure that the oxygen gas from the air exerts on the blood as it passes through the lungs.

 Flammability and Oxygen   (Site not responding. Last check: 2007-10-26)
Oxygen is a strong or hi-energy oxidizer, true, but it is an oxidizer, so it is not a fuel, so they do not call it flammable.
Actually, oxygen is the positive terminal, and fuel is the negative terminal, in a fuel cell.
Oxygen is the most common oxidizing agent (there is a reason for the similarity in the words oxygen and oxidizing...) and it is also one of the strongest.

The oxygen is essential to the survival of each of those cells: oxygen and glucose are the fuel sources that are “burned” in providing the cell’s energy.
Carbon dioxide, the byproduct of the burning process, is then carried away from the cell by hemoglobin as it travels back to the heart and lungs through the venous system.
Oxygen is, then, not delivered to the cells (including brain cells), and carbon dioxide is not transported away from the cells.

 Mine Rescue Manual - Chapter Four - Mine Fires
The flaming mode of combustion, such as the burning of logs in the fireplace, is represented by the fire tetrahedron (fuel, temperature, oxygen and the uninhibited chemical chain reaction).
The process of extinguishing by cooling depends on cooling the fuel to a point where it does not produce sufficient vapour to burn.
This is the same process as boiling water to evaporate it, and water in a container evaporating in sunlight.

In fact, oxygen is more destructive than ultraviolet, for the large molecules needed to build the first living things could never have formed if the atmosphere had been as rich in oxygen then as it is now.
Their fermenter descendants still live today by hiding from oxygen in mud or in other safe places such as the stomachs of cows, where they help digest hay, or the bead-like root nodules of peas and beans, where they fix nitrogen to enrich the soil.
This process of burning food with oxygen is what we call respiration -- the third way of making ATP, after the fermentation of the bubblers and the photosynthesis of the bluegreens.

 V2ROCKET.COM - Design & Tech Data
In the burning process, first oxygen is injected, without entering air, then spontaneous burn of the fuel and liquid oxygen, then gasses flow with great speed to the nozzle end.
Fully fueled, the V2 had 4900 kg A-Stoff which was liquid oxygen with a temperature of minus 183 degrees Celsius, and 3710 kg of a mixture of 75% Ethyl alcohol and 25% water, called B-Stoff.
Each second, 58 kg alcohol of 23 bars had to be pressed via 1224 injection ports, and 72 kg oxygen with a pressure of 17.5 bars via 2160 injection ports into the burning chamber, that eventually at a pressure of 15 bars brought the temperature to 2500 degrees Celsius.

 The Combustion Process
This process in known as “Combustion.” Combustion is a chain reaction chemically similar to photosynthesis in reverse.
The tremendous amount of heat that is produced in the burning process is the major reason that the suppression of wildfires is such a difficult task and why the use of prescribed fire is a complex and exacting process requiring knowledgeable and experienced people.
The combustion process or “fire” is sometimes called “rapid oxidation.” It is similar to the formation of rust on iron or the decay of dead wood in the forest, except that the process is drastically speeded up.

 McKenna Process Company - Joliet, Illinois - 1897-1941
The McKenna Process Company was originally organized in 1896 for the purpose of "renewing" or rerolling worn railroad rails, but finally this industry waned as Open Hearth steel came into more general use.
The method used at Galesburg was a milling down of the two worn contact surfaces of a bar, making a smaller bar with new contact surfaces to fit a smaller rail instead of to fit the same rail as I considered essential.
The process of milling was laborious, slow and costly.

 The Second Law of Thermodynamics (5)
We can take in concentrated energy in the form of oxygen plus food and use some of that energy unconsciously to synthesize "uphill" complex biochemicals and to run our bodies, consciously for mental and physical labor, excreting diffused energy as body heat and less concentrated energy substances.
Living creatures are essentially energy processing systems that cannot function unless a multitude of "molecular machines", biochemical cycles, operate synchronically in using energy to oppose second law predictions.
However, in a micro sense it is a chemical process because in any break chemical bonds are ruptured all along the line of the break as well as complexly broken and reformed near that break line.

The burning of these sugars is a 'clean' process.
When the body burns the sugars with the help of oxygen there are waste products produced.
The waste product of the burning-process without oxygen is ammonia which is connected with carbon-dioxide and forms the less toxic ureum which is excreted by the kidneys.

Life is the process of bodies, not one of their parts, and in this book we maintain that the same is true for Gaia-Earth -- that life is its process, its metabolic system, its particular kind of working organization, not one of its parts.
It is very dependent on solar energy, to be sure, but the Sun does not burn up faster because the Earth uses its energy, and the waste heat given off by the Earth cannot be construed as degrading its cold space environment.
We are only beginning to discover how complicated are the structure and process of our own Sun star, and we still have much to learn about the way our own planet rearranges its matter into those lively chemical patterns we all agree to call living organisms.

During the CNO cycle, carbon, nitrogen, and oxygen catalyze the nuclear reaction, so the total number of carbon, nitrogen, and oxygen nuclei remains the same.
The CNO cycle powers the hydrogen burning that occurs in main-sequence stars with more than 1.5 solar masses and in giants and supergiants of all masses.
For main-sequence stars greater than a few solar masses, hydrogen burning by the CNO bi-cycle is the main source of energy.

 PCWorld.com - Burning Questions: When Good Discs Go Bad
At best, the disc will fail immediately during the burn process; this is a best-case scenario because then you know from the start that the disc is faulty.
These errors won't interrupt the burning process, and since write-once and rewritable DVD media have built-in error correction to compensate for scratches and other abnormalities on the disc (as do their CD cousins), any errors will be virtually invisible to you.
And if anything in that production process is off, it could, in time, affect the integrity of the data you've burned to a disc.
