In 1997, the charity introduced a U.S. Libraries initiative with a goal of "ensuring that if you can get to a public library, you can reach the internet". Only 35% of the world's population has access to the Internet. The foundation has given grants, installed computers and software, and provided training and technical support in partnership with public libraries nationwide in an effort to increase access and knowledge. Helping provide access and training for these resources, this foundation helps move public libraries into the digital age.

Spirometry is recommended to aid in diagnosis and management. It is the single best test for asthma. If the FEV1 measured by this technique improves more than 12% following administration of a bronchodilator such as salbutamol, this is supportive of the diagnosis. It however may be normal in those with a history of mild asthma, not currently acting up. As caffeine is a bronchodilator in people with asthma, the use of caffeine before a lung function test may interfere with the results. Single-breath diffusing capacity can help differentiate asthma from COPD. It is reasonable to perform spirometry every one or two years to follow how well a person's asthma is controlled.

Ah, so.. Single-breath diffusing capacity

Congo is located in the central-western part of sub-Saharan Africa, along the Equator, lying between latitudes 4N and 5S, and longitudes 11 and 19E. To the south and east of it is the Democratic Republic of Congo. It is also bounded by Gabon to the west, Cameroon and the Central African Republic to the north, and Cabinda (Angola) to the southwest. It has a short coast on the Atlantic Ocean.
