The current U.S. astronaut aboard Mir, Mike Foale, has put on a happy face despite the setbacks, but CNN has been told a lack of oxygen and a surplus of carbon dioxide may have contributed to a series of onboard mistakes which threatened the health of the station and could have killed the crew.
If, however, they are subjected instead to pyrolysis a process of controlled burning in a low-oxygen atmosphere the result is charcoal, a substance that is mostly elemental carbon.
ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well
She had no firsthand knowledge of what it was like to feel your breath being squeezed off, to live in a world whose very atmosphere was a constant taunt, whose bountiful oxygen was as capriciously out of reach as a rainbow.
Each one had a seal at the top which was removed before it was fired, setting off a chemical reaction to produce oxygen as well as a lot of heat, the coroner heard.
In the simplest terms, a fuel cell combines hydrogen and oxygen in a process that releases electricity, heat and water.
Grey speculated that a manufacturing defect could have triggered a physical short-circuit, which caused heating, released oxygen and led to a fire.
One senses a lack of oxygen in tissue, which is a sign of a tumor.
The gas is then fed into a stack of solid oxide fuel cells, where a chemical reaction between hydrogen and oxygen occurs, producing electricity, water vapor and a tiny amount of carbon dioxide.
Clusters of zinc atoms then mix with a reactive gas, usually oxygen, and cool to a solid.
If you zap purified water with electric current, you can split apart a water molecule into a positively charged hydrogen ion and a negatively charged hydroxide ion (oxygen attached to hydrogen).
Doctors also assess lung performance using a measure called Vo2 max - the highest volume of oxygen a person can consume during exercise.
Experts from the National Transportation Safety Board, which has been investigating the accident, suspect that a cargo of more than 100 oxygen generators -- which provide oxygen in case of a cabin emergency -- contributed to the fire.
The above might normally be acceptable given a Washington whose oxygen is government spending, but not for a small government establishment that for years has paid lip service to the importance of reducing its size.
FORBES: The Small Government Establishment Joins the Establishment
The hose is connected to a machine that lowers the air's oxygen content, thereby simulating a mountaintop environment.
Any simple alcohol is composed of a number of carbon and hydrogen atoms (like a hydrocarbon such as petrol) together with a single oxygen atom.
Roughly 25, 000 Americans are stuck in a vegetative state as a result of suffering brain damage from a car accident or other trauma, or after their brain has been deprived of oxygen following a stroke or heart attack.
When heated in the absence of oxygen (a process called pyrolysis), keratin forms hollow tubular structures six millionths of a metre across and riddled with microscopic pores, much like carbon nanotubes.
ECONOMIST: Chicken feathers could provide a high-capacity store
If you can figure out a way to get breathable oxygen from moon rocks, that will fetch a quarter-million-dollar price.
More experiments with the stuff in the brightest square (a combination of oxygen with the metals gallium and gadolinium) led to a surprising conclusion.
On 23 February 1997, a serious fire broke out, triggered by a chemical oxygen generator.
In this configuration, the HTP is passed over a catalyst pack to decompose it into steam and oxygen, but instead of igniting a fuel grain, this superhot gas is allowed simply to vent through the chamber nozzle.
To keep turbine sales spinning, Immelt has turned to a process that partially burns pulverized coal in the presence of pure oxygen to turn it into a flammable gas that can drive linked gas and steam turbines.
The source of the fire has still not been pinpointed, but it was widely speculated that a group of oxygen generators in the cargo hold may have caused or contributed to a blaze in the cargo hold of the DC-9.
The cause of death was a hypoxic brain injury, caused by a severe decrease in oxygen to the brain.
But Dr Chen's observation suggested this electrolysis could happen because the dioxide becomes a conductor once a tiny amount of oxygen is removed from it.
The IBM team's innovation to create the first single molecule picture, of a molecule called pentacene, was to use the tip to pick up a single, small molecule made up of a carbon and an oxygen atom.
BBC: Atomic bond types discernible in single-molecule images
Its maker, a Dutch alchemist called Cornelius van Drebbel, is thought to have used a primitive oxygen-supply system, based on saltpetre, to prevent the crew from asphyxiating.
You too have developed a Jedi-like ability to quickly skip over Lifetime, Oxygen, and The Hallmark Channel while spending a little more time on ESPN and the Sci-Fi Channel.
ENGADGET: The Clicker -- Why are there 18 standards for HDTV?
The researchers hope their work may lead to a COPD treatment that mimics the adjustments of a healthy body to an oxygen-depleted state.
WSJ: Mayo Clinic Researchers on Everest Study High Altitude's Effects on the Body
Klimeck died Sunday after spending more than two weeks in a medically induced coma due to extensive brain injuries from a prolonged lack of oxygen after accidentally hanging himself, according to the Hospital Santa Casa de Misericordia, in the neighboring city of Itapeva.
