We have oxygen shipped up to us in the Space Shuttle and also in a Russian spacecraft called a Progress. We have tanks which we store oxygen on the Station once it is transferred from these spacecraft. We also make oxygen from water using a machine called Elektron. It uses a concept called electrolysis to break down water from H2O to hydrogen and oxygen.

quot;In a 24 hour day, the adult man uses... (approx.) 8 pounds of oxygen... " - A. Schatz, discoverer of streptomycin, in Cancer News Journal, v.12, n.2, p.6, June 1977. The average man consumes 6 to 8 pounds of oxygen, 4 pounds of food, and 2 pounds of water. More oxygen goes into our bodies than the other two combined. I would say oxygen is important. Some ancient cultures installed big pipes on hilltops and pumped fresh mountain air down to the congested cities below. See similar questions...

Because nobody is getting enough oxygen. We are all suffering from oxygen depletion in one form or another. Epidemics of both infectious and chronic degenerative diseases are indicatives of a lack of the fundamental nutrient OXYGEN needed to affect a rapid, dependable healing process. The greatest energy source in our bodies for killing pathogens and repairing tissue is oxygen. See similar questions...

No. Compared to the oxygen reserves in the atmosphere and green plant oxygen generators, trees are not major producers. Ocean plants produce far more oxygen than trees, which makes some sense considering the ocean covers about three-quarters of the Earth's surface.. Remember that the purpose of photosynthesis is not to produce oxygen, but to produce sugars. See similar questions...

Since there's no gravity up here we have to be very careful with our tools, and we basically have what we call a 'tether protocol' up here. Every single thing that we grab onto once we're outside the cockpit, we're actually tethered to with these tethers and the hooks that are on the ends of these tethers actually require two separate actions to open. In that way we don't accidentally open one of the hooks and therefore lose one of our tools. See similar questions...

If your facility sells oxygen and medical devices to a specific patient, your establishment must register as a Nonprescription Drug Outlet - Class C. With a Class C registration, you can also sell to facilities but only if the sale is patient specific. A wholesaler and manufacturer may sell in bulk (not patient specific) to other facilities, as well as patients. See similar questions...

The cornea is unusual in that it is transparent, it has to be otherwise light could not enter the eye. The tissues that make up the cornea are able to maintain their transparency partly by not having blood vessels flowing through them. Without blood vessels, the cornea must get its oxygen directly from the air. The oxygen first dissolves in the tears and then diffuses throughout the cornea to keep it healthy. Equally important is carbon dioxide, which is the waste product of a healthy cornea. See similar questions...

Air/Fuel Ratio Primer: When air and gasoline are mixed together and ignited, the chemical reaction requires a certain amount of air to completely burn all of the fuel. The exact amount is 14.7 lbs of air for every pound of fuel. This is called the "stoichiometric" air/fuel ratio or 14.7:1 a/f. It's also referred to the Greek letter "lambda." Lean mixtures improve fuel economy but also cause a sharp rise in oxides of nitrogen (NOX). See similar questions...

Although not necessary, addition of oxy-plus (liquid oxygen) can often be of benefit in increasing yield and helping the plant perform in demanding environments. See similar questions...

oxygen diffusion barrier, a special coating applied to the tubing, reduces the amount of oxygen entering the tubing from the surrounding air. Oxygen can shorten the life of some heat sources. However, those heat sources affected by oxygen are rare, an even in these cases, there are solutions to this problem which cost less and work better. See similar questions...

The EMU (Extravehicular Mobility Unit) has a drink bag which velcros to the front interior of the suit. The bag comes in two different sizes 21 oz and 32 oz and it is crew choice as to which bag they fly. The bag has a drink tube with a valve which prevents free flow of water into the suit. The valve is opened when the crew sucks on the tube for water. Their food was provided by a fruit bar wrapped in an edible rice paper. See similar questions...
