Oxygen Extraction by the Lungs - Vernier
Oxygen is required for cell metabolism. During inhalation air is brought into the lungs, where oxygen is extracted. Oxygen passes into the bloodstream at the membrane between the alveoli and pulmonary capillaries. The quantity of oxygen extracted from the air is dependent on the composition of the air and on the efficiency of the lungs. The percent concentration of oxygen in air on earth is ...

Physics Of A Golf Swing - Real World Physics .
The physics of a golf swing is deceptively more complicated than one might imagine. At first glance it might appear as simple as swinging a club and hitting the ball. But in fact, there is quite a bit more to it. There is the importance of technique obviously, but there is also some interesting physics that goes into making the "perfect" golf shot.

High-fat diet, muscular lipotoxicity and insulin .
Importantly, the reduction in PGC-1α may be a result of low physical activity, consumption of high-fat diets and high plasma fatty acid levels. Mitochondrial function can also be impaired as a result of enhanced mitochondrial damage by reactive oxygen species. Fatty acids in the vicinity of mitochondria are particularly prone to lipid peroxidation. In turn, lipid peroxides can induce ...

Metal stocks and sustainability | PNAS
Jan 31, 2006· The relative proportions of metal residing in ore in the lithosphere, in use in products providing services, and in waste deposits measure our progress from exclusive use of ore toward full dependence on sustained use of recycled metal. In the U.S. at present, the copper contents of these three repositories are roughly equivalent, but metal in service continues to increase.

How to Purify Compounds - Organic Chemistry
Explanation: . In organic chemistry, chemists often exploit the acidic and basic properties of side products in order to remove them. Compounds I-IV are all organic-soluble, however, if they are converted to a sodium salt via deprotonation with sodium hydroxide, they will become fully soluble in the aqueous sodium hydroxide solution and be washed away with this layer.

The electrons in the compound absorb energy, making them "excited." The electrons can't maintain this high level, though, so they jump back to a lower level, releasing light energy (photons) in the process.

Ageing and health - World Health Organization
At the biological level, ageing results from the impact of the accumulation of a wide variety of molecular and cellular damage over time. This leads to a gradual decrease in physical and mental capacity, a growing risk of disease, and ultimately, death. But these changes are neither linear nor consistent, and they are only loosely associated with a person's age in years. While some 70 year ...
